Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer knitting, in particular to a cam device of a flat knitting machine, a glove machine and a knitting method. BACKGROUND

[0002] The needle guide head assembly of the conventional glove knitting machine on the market is involved in three kinds of knitting: 1. knitting from the rubber band cam; 2. knitting from the lifting cam; 3. reverse sealing knitting, and the structure is basically only two kinds, the first kind: only with the function of forward lifting, and the reverse lifting is only used for sealing. In the process of forward lifting, the running track of the needle stitch is: first rising along the slope of the rubber band cam and reaching the highest point, then descending along the slope of the rubber band density cam to the bottom, then rising along the slope of the forward lifting cam to the highest point, then descending along the cam track, and descending to the position of the forward density cam to continue descending along the slope of the forward density cam to the bottom, so as to complete a one-way knitting of weaving into rubber band and then into yarn.

[0003] The second kind: with the functions of forward lifting and reverse lifting, which is called as jacquard glove machine or computer flat knitting machine in the industry. If the reverse lifting is performed after the forward lifting in the same knitting row, the running track of the needle stitch is: after passing through the bottom of the rubber band density cam, it still moves through the bottom of the reverse density cam. Although this working mode can realize the reverse lifting, it will inevitably increase the descending amplitude of the rubber band knitting needle, and then cause the rupture of the rubber band or the uncontrollable size and tightness of the rib part of the glove.

[0004] Therefore, the glove knitting machine in the industry generally does not implement the working mode of reverse lifting when knitting the rib part, and even if the reverse lifting is needed, the following ways will be adopted:

[0005] 1. not knitting the rubber band in the same knitting row of implementing the reverse lifting (industry term is called folding line);

[0006] 2. if the knitting of the rubber band is needed during the reverse lifting, in order to prevent the rupture of the rubber band or affect the knitting quality of the rib part, only the reverse density cam can be greatly adjusted to make the bottom of the reverse density cam and the bottom of the rubber band density cam reach the same height, so that the reverse density cam will not change the descending amplitude of the rubber band knitting needle. However, this will cause the high knitting density of the yarn in the knitting row, which cannot realize normal knitting.

[0007] In summary, the ordinary knitting glove machine or flat knitting machine cannot normally realize both reverse knitting and rubber thread knitting in the same flat knitting row of rib part, and therefore cannot be well applied to the processing mode of bidirectional synchronous knitting. In view of this problem, the Chinese invention patent with application number 202210746452.9 discloses a needle guide machine head assembly suitable for bidirectional knitting of glove rib part, which comprises a mounting plate and a needle guide assembly mounted thereon, the needle guide assembly comprises a rubber thread guide needle structure and a yarn guide needle structure, etc. By improving the needle guide machine head assembly, the knitting glove machine can realize both forward and reverse needle lifting when knitting the rib part of the glove, greatly improving the production capacity of the knitting glove machine.

[0008] However, due to the limitation of its own structure, this technical solution cannot be flexibly converted between bidirectional knitting and single-sided knitting, and still has the problem of not being able to improve the glove processing efficiency well; and the rubber thread woven can only participate in the next row of yarn knitting, which greatly increases the stress path and stress time of the rubber thread, and long-term stress of the rubber thread can easily cause the rubber thread to break and skip, affecting the rubber knitting effect and reducing the knitting efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0144] As attached Figure 1 To be continued Figure 6 As shown, this embodiment of the invention provides a cam device for a horizontal knitting machine. The function of the cam device is to cooperate with the needle bed to knit fabric. When applied in a glove machine, it generally includes two cam devices for the horizontal knitting machine, referred to as the first needle guide head 1 and the second needle guide head 2, respectively. The first needle guide head 1 is used to knit the first side of the glove, and the second needle guide head 2 is used to knit the second side of the glove, as shown in the attached figure. Figure 1As shown, when the first needle guide head 1 and the second needle guide head 2 are mounted on the needle bed, the front of the triangle faces the needle bed, enabling them to perform reciprocating knitting movements in the same direction along the knitting direction to simultaneously knit the first and second sides. The first and second sides are positioned opposite each other during the knitting process, and the corresponding first needle guide head 1 and second needle guide head 2 are also positioned opposite each other. When applied in a knitting device, the device includes two needle beds spaced apart from each other, extending along the knitting direction. The first needle guide head 1 knits the first side corresponding to one needle bed, and the second needle guide head 2 knits the second side corresponding to the other needle bed. The first side includes a plurality of first coil rows connected vertically in sequence, each first coil row including a plurality of first coils connected horizontally in sequence. The second side includes a plurality of second coil rows connected vertically in sequence, each second coil row including a plurality of second coils connected horizontally in sequence. It is worth noting that in this embodiment, the vertical direction can be perpendicular to the horizontal plane or not perpendicular to the horizontal plane, the horizontal direction can be horizontal or not horizontal, and the angle between the vertical and horizontal directions can be a right angle or not a right angle. When the first needle head 1 and the second needle head 2 reciprocate in the same direction along the knitting direction, they can be synchronized to perform the seam knitting. The first needle head 1 and the second needle head 2 sew the ends of the first and second surfaces together. If the first needle head 1 and the second needle head 2 are offset by a set stroke, they can independently knit the corresponding surfaces. The first needle head 1 independently knits the first surface, and the second needle head 2 independently knits the second surface. They then join at the edge, connecting the sides of the first and second surfaces together. The knitting direction includes a parallel and opposite first knitting direction and a second knitting direction. The knitting direction is the knitting direction of the glove machine, generally from left to right or from right to left when the user is facing the glove machine.

[0145] To realize the knitting function of the first needle guide head 1 and the second needle guide head 2, the triangular device includes a triangular base plate 10, a yarn needle guide mechanism and an elastic needle guide mechanism set on one end face of the triangular base plate 10. The yarn needle guide mechanism is used to knit the finger and palm parts of the glove, and the elastic needle guide mechanism and the yarn needle guide mechanism are used to knit the cuff part of the glove. Specifically, the yarn guide needle mechanism includes a central cam 11, a knitting needle cam 19, a first start-up cam 12, a second start-up cam 13, a first density cam 14, and a second density cam 15. The central cam 11 is located in the middle of the cam base plate 10. The first start-up cam 12 is located on one side of the central cam 11, and the second start-up cam 13 is located on the other side of the central cam 11. The central cam 11, also known as the Zhongshan cam, functions as a top needle. The knitting needle cam 19, also known as the herringbone cam, limits the highest position of the knitting needle 40 and guides the knitting needle 40. Both the first start-up cam 12 and the second start-up cam 13 are start-up cams. When the front of the cams in the cam device faces the user, as shown in the attached diagram... Figure 2As shown, the middle triangle 11 is located in the middle of the triangle base plate 10, the needle triangle 19 is located above the middle triangle 11 and is set at intervals, the first starting triangle 12 is located to the left of the middle triangle 11, so it can also be called the left starting triangle, the first density triangle 14 is set at intervals above the first starting triangle 12, so it can also be called the left density triangle, the second starting triangle 13 is located to the right of the middle triangle 11, so it can also be called the right starting triangle, and the second density triangle 15 is set at intervals above the second starting triangle 13, so it can also be called the right density triangle.

[0146] In this embodiment, the first starting triangle 12 can independently extend and retract along the thickness direction of the triangle base plate 10, and has a full-height position and a flush position; the first density triangle 14 can move along the through groove 101 on one side of the middle triangle 11; the second starting triangle 13 can independently extend and retract along the thickness direction of the triangle base plate 10; the second density triangle 15 can move along the through groove 101 on the other side of the middle triangle 11; the middle triangle 11 can independently extend and retract along the thickness direction of the triangle base plate 10, and has a full-height position and a half-height position; thus, a variety of knitting patterns can be combined, and the switching between unidirectional knitting and bidirectional knitting can be easily realized.

[0147] In this embodiment, the elastic band guide needle mechanism in the triangular device is used to cooperate with the yarn guide needle mechanism to realize elastic band weaving. Both the first guide needle head 1 and the second guide needle head 2 have elastic band guide needle mechanisms. The elastic band guide needle mechanism is located on the side of the second starting triangle 13 away from the middle triangle 11, including the elastic band triangle 16 and the elastic band guide triangle 17. The elastic band triangle 16 can independently extend and retract along the thickness direction of the triangle base plate 10, and has a half-height position and a flush position. It can cooperate with the yarn guide needle mechanism to realize more weaving patterns. When elastic band weaving is required, it is a pattern of weaving the elastic band first and then weaving the yarn. The elastic band is not easy to break or skip stitches.

[0148] In this embodiment, the flush position refers to the front face of the triangle being flush with the front face of the triangle base plate 10. It should be noted that during actual installation, due to processing or assembly errors, the front face of the triangle and the front face of the triangle base plate 10 may not be perfectly flush; the actual flush position is a basic flush with acceptable error. It should also be noted that triangles in the flush position do not participate in the weaving process and therefore cannot form a guide needle channel.

[0149] In this embodiment, the half-height position refers to the height at which the triangle protrudes from the triangle base plate 10, allowing the low needle to cross the triangle surface and the high needle to enter the guide needle channel along the guide needle surface (edge) of the triangle. The full-height position refers to the height at which both the high and low needles enter the guide needle channel along the guide needle surface (edge) of the triangle. The full-height positions of the first needle-opening triangle 12 and the middle triangle 11 are basically the same, and the half-height positions of the middle triangle 11 and the elastic band triangle 16 are basically the same. The half-height position is compared to the full-height position, and its height can be 35%-65% of the full-height position. For example, when the full-height position is 4±0.5mm, the half-height position is 2±0.5mm.

[0150] Based on the above structure, in the cam device of this embodiment, the first starting cam 12, the first density cam 14, the knitting needle cam 19, the second starting cam 13, the second density cam 15, and the middle cam 11 at full height form a first bidirectional needle guide channel. Specifically, taking the first needle guide head 1 as an example, as shown in the attached diagram... Figure 1 As shown, when the first needle guide head 1 moves along the first knitting direction, the heel of the knitting needle 40 enters the needle guide channel between the first start-up triangle 12 and the first density triangle 14, rises along the needle guide surface of the first start-up triangle 12, then passes through the apex of the middle triangle 11, and is then controlled and guided by the needle triangle 19, causing the heel of the knitting needle 40 to descend along the needle triangle 19, and then continue to descend along the second density triangle 15. Adjusting the height of the second density triangle 15 adjusts the stitch count. Finally, the heel of the knitting needle 40 passes through the bottom of the second density triangle 15 and exits the needle guide channel, which is a full-stitch needle guide channel in one direction. When the first needle guide head 1 moves along the second knitting direction, the heel of the knitting needle 40 rises from the second start-up triangle 12, passes through the apex of the middle triangle 11, and is then controlled and guided by the needle triangle 19, causing the heel of the knitting needle 40 to descend along the needle triangle 19, and then continue to descend along the second density triangle 15. Adjusting the height of the second density triangle 15 adjusts the stitch count. Finally, the heel of the knitting needle 40 passes through the bottom of the second density triangle 15 and exits the needle guide channel, which is a full-stitch needle guide channel in one direction. The needle enters the guide needle channel between angle 13 and the second density triangle 15, rises along the guide needle surface of the second starting triangle 13, then passes through the apex of the middle triangle 11, and is then controlled and guided by the needle triangle 19, causing the heel of the needle 40 to descend along the needle triangle 19, and then continue to descend along the first density triangle 14. Adjusting the height of the first density triangle 14 adjusts the needle gauge value. Finally, the heel of the needle 40 passes through the bottom of the first density triangle 14 and exits the guide needle channel, which is a full-gauge guide needle channel in another direction; thus, the first guide needle head 1 can knit in both the first knitting direction and the second knitting direction. Therefore, the first guide needle head 1 has a first bidirectional guide needle channel, that is, a bidirectional full-gauge guide needle channel, as shown in the attached figure. Figure 2 As shown, at this time, the elastic band triangle 16 is in a flush position and does not participate in the knitting, and the needle heel passes directly over the elastic band triangle 16.

[0151] Based on the above structure, the first starting triangle 12, the first density triangle 14, the needle triangle 19, the second starting triangle 13, the second density triangle 15, and the middle triangle 11 at half-height position form a second bidirectional needle guide channel; the second bidirectional needle guide channel can be a bidirectional hanging needle guide channel. Taking the first needle guide head 1 as an example, specifically, when the first needle guide head 1 moves along the first knitting direction, the heel of the needle 40 enters the needle guide channel between the first starting triangle 12 and the first density triangle 14, rises along the needle guide surface of the first starting triangle 12, and since the middle triangle 11 is at half-height position, the heel of the low-needle needle 40 is not obstructed, crosses the middle triangle 11, and then continues to descend along the second density triangle 15. Adjusting the height of the second density triangle 15 can adjust the needle gauge value. Finally, the heel of the needle 40 passes through the bottom of the second density triangle 15 and exits the needle guide channel, which is a unidirectional hanging needle guide channel; when the first needle guide head 1 moves along the second knitting direction, the heel of the needle 40 enters the needle guide channel between the first starting triangle 12 and the first density triangle 14, rises along the needle guide surface of the first starting triangle 12 ... The needle enters the guide channel between the second starting triangle 13 and the second density triangle 15, rising along the guide surface of the second starting triangle 13. Since the middle triangle 11 is at half its height, the heel of the low-needle needle 40 is unobstructed, crossing the middle triangle 11 and continuing to descend along the first density triangle 14. Adjusting the height of the first density triangle 14 adjusts the stitch value. Finally, the heel of the needle 40 passes through the bottom of the first density triangle 14 and exits the guide channel, which is a needle guide channel for hanging stitches in another direction. Thus, the first guide needle head 1 can perform hanging stitch knitting in both the first and second knitting directions. Therefore, the first guide needle head 1 has a second bidirectional guide needle channel, i.e., a bidirectional hanging stitch guide channel, as shown in the attached diagram. Figure 2 As shown, at this time, the elastic band triangle 16 is in a flush position and does not participate in the knitting, and the needle heel passes directly over the elastic band triangle 16.

[0152] In the above structure, both the first starting triangle 12 and the second starting triangle 13 can independently extend and retract along the thickness direction of the triangular base plate 10. The first starting triangle 12 (left starting triangle) can actively move from its full height position to its flush position, and the second starting triangle 13 (right starting triangle) can actively move from its full height position to its flush position, or it can be passively moved from its full height position to its flush position by the action of the needle heel. To simplify the structure of the triangle device, in this embodiment, the second starting triangle 13 is passively moved from its full height position to its flush position by the action of the needle heel. The specific structure is the same as conventional technology and will not be described again here.

[0153] Based on the above structure, the second starting triangle 13, the middle triangle 11 at full height, the needle triangle 19, and the first density triangle 14 form the first unidirectional needle guide channel. The first starting triangle 12 is actively in a flush position and does not participate in knitting. Taking the first needle guide head 1 as an example, specifically, when the first needle guide head 1 moves along the second knitting direction, the heel of the needle 40 enters the needle guide channel between the second starting triangle 13 and the second density triangle 15, and rises along the needle guide surface of the second starting triangle 13. Since the middle triangle 11 is at half height, the heel of the low-needle needle 40 is not obstructed, crosses the middle triangle 11, and continues to descend along the first density triangle 14, adjusting the first density triangle 19. The height of 4 can be adjusted to the gauge value. Finally, the heel of the needle 40 passes through the bottom of the first density triangle 14 and exits the guide needle channel. At this time, the elastic triangle 16 is in a flush position and does not participate in knitting. The heel directly passes over the elastic triangle 16. Since the first starting triangle 12 is in a flush position, when the first guide needle head 1 moves along the first knitting direction, it cannot start the needle. The heel presses over the inclined surface of the second starting triangle 13, moving the second starting triangle 13 from the full height position to the flush position. Then the heel directly passes over the elastic triangle 16. After the first guide needle head 1 changes direction, it continues to move and knit along the second knitting direction. Repeat the above steps. The first unidirectional guide needle channel is the unidirectional full gauge guide needle channel.

[0154] Based on the above structure, the elastic band triangle 16 at half-height position, together with the second starting triangle 13, the middle triangle 11, and the first density triangle 14, forms a second unidirectional needle guide channel where the elastic band is woven in first, followed by the yarn. Taking the second needle guide head 2 as an example, as shown in the attached diagram... Figure 4 As shown, the elastic band triangle 16 is in a half-height position. The second guide needle head 2 moves along the second knitting direction. The heel of the knitting needle 40 enters the guide needle channel between the elastic band triangle 16 and the elastic band guide triangle 17, and rises along the starting surface of the elastic band triangle 16. After reaching the apex of the elastic band triangle 16, it descends along the second density triangle 15 and enters between the second starting triangle 13 and the second density triangle 15. It rises along the starting surface of the second starting triangle 13, and then passes through the apex of the middle triangle 11. The needle 40 is then controlled and guided by the knitting needle triangle 19, causing the heel of the knitting needle 40 to descend along the knitting needle triangle 19 and then continue to descend along the first density triangle 14. Adjusting the height of the first density triangle 14 can adjust the gauge value. Finally, the heel of the knitting needle 40 passes through the bottom of the first density triangle 14 and exits the guide needle channel. The second unidirectional guide needle channel is the unidirectional elastic band knitting channel. At this time, if the second guide needle head 2 moves along the first knitting direction, the elastic band triangle 16 can be controlled to actively be in a flush position to avoid the needle heel hitting the elastic band triangle 16.

[0155] In summary, the cam device of this embodiment can not only perform bidirectional full-mesh knitting and bidirectional hanging-mesh knitting, but also unidirectional full-mesh knitting and unidirectional elastic band knitting, making the knitting function more diverse and the knitting efficiency higher. Furthermore, when elastic band knitting is not needed, the needle heel of the knitting needle 40 will not contact the elastic band cam 16, avoiding wear and wasted stroke on the needle heel and reducing the impact on the knitted fabric. On the other hand, when the elastic band cam 16 is in a half-height position, when the first guide needle head 1 or the second guide needle head 2 moves along the second knitting direction, the needle heel of the knitting needle 40 corresponding to the elastic band will first enter between the elastic band cam 16 and the elastic band guide cam 17, and then enter between the second start-up cam 13 and the second density cam 15. This achieves the first guide needle channel where the elastic band is knitted in first and the yarn is knitted in later. Therefore, the elastic band can be directly knitted into the yarn loop in the current row, instead of waiting to be knitted into the yarn loop in the next row, making the elastic band less prone to breakage or skipped stitches. When the elastic band triangle 16 is in a half-height position for elastic band weaving, the second density triangle 15 can also be used to adjust the height of the elastic band needle, so that the elastic band can be precisely matched with the insertion port of the sinker, avoiding the elastic band from hitting the insertion pin of the sinker and breaking, thereby reducing the probability of elastic band breakage from multiple aspects.

[0156] Preferably, as shown in the appendix Figure 2 As shown, when the elastic band triangle 16 is in a flush position, the projection of the second density triangle 15 in the thickness direction of the triangle base plate 10 partially overlaps with the projection of the elastic band triangle 16 in the thickness direction of the triangle base plate 10. The second density triangle 15 can move along the through groove on the triangle base plate 10, causing the projection of the second density triangle 15 in the thickness direction of the triangle base plate 10 to be misaligned with the projection of the elastic band triangle 16 in the thickness direction of the triangle base plate 10. The elastic band triangle 16 can rise to a half-height position. After the second density triangle 15 moves up, a portion of its structure is spaced apart from the elastic band triangle 16 in the height direction of the triangle base plate 10, forming part of the elastic band guide needle channel. This also allows the second density triangle 15 to adjust the height of the elastic band needle movement. In this embodiment, without increasing the size of the triangle base plate 10, the elastic band triangle 16 is placed near the second density triangle 15, thus not increasing the existing knitting stroke. The structure of the first guide needle head 1 and the second guide needle head 2 is more compact, improving knitting efficiency.

[0157] Preferably, a pressure pin triangle 18 is provided on the side of the triangular base plate 10 near the first density triangle 14 or on the other side near the elastic band guide triangle 17. The pressure pin triangle 18 is raised and lowered along the pressure pin groove 102 vertically opened on the triangular base plate 10 and abuts against the side wall of the first density triangle 14 or the elastic band guide triangle 17. (See attached diagram) Figure 2 In the first needle guide head 1 shown, the pressure needle triangle 18 is disposed on the side of the triangle base plate 10 near the first density triangle 14 and abuts against the first density triangle 14; as shown in the attached figure. Figure 4In the second needle guide head 2 shown, the pressure needle triangle 18 is located on the side of the triangle base plate 10 near the elastic band guide triangle 17 and abuts against the elastic band guide triangle 17. Then, as shown in the attached diagram... Figure 1 As shown, when the first needle guide head 1 and the second needle guide head 2 are installed in the glove machine, the pressure needle triangle 18 faces the same direction as the phone case.

[0158] Based on the above-mentioned bidirectional knitting mode, the cam device in this embodiment further includes a first return needle assembly 20 and a second return needle assembly 30, which are located on both sides of the yarn guide needle mechanism. The first return needle assembly 20 forms a first return needle path 21, and the second return needle assembly 30 forms a second return needle path 31. The highest points of both the first return needle path 21 and the second return needle path 31 are higher than the knitting needle cam 19, and the height of the heel of the knitting needle 40 is the same. This ensures that when the cam device knits along the first knitting direction or the second knitting direction, the heel of the knitting needle 40 can be corrected by the first return needle assembly 20 or the second return needle assembly 30 before entering the guide needle channel or after leaving the guide needle channel, so that the heel of the knitting needle 40 returns to a certain height and remains uniform, thereby ensuring the consistency of the knitting loops and the knitting quality of the fabric.

[0159] In this embodiment, both the first return needle path 21 and the second return needle path 31 are located above the needle triangle 19. Therefore, the first return needle assembly 20 and the second return needle assembly 30 forming the first return needle path 21 and the second return needle path 31 are installed on the upper sides of the triangle base plate 10, rather than on the middle sides of the triangle base plate 10. This shortens the lateral volume of the triangle base plate 10, and the structure of the triangle device can be more compact. The needle 40 has two needle heels, one is the lower needle plate needle heel 41, and the other is the upper return needle heel 42. In this embodiment, the needle heel that contacts the first return needle assembly 20 and the second return needle assembly 30 is not the needle plate needle heel 41 that enters the needle guide channel, but the return needle heel 42 located above the needle plate. The return needle heel 42 is used less frequently in the entire knitting process, and therefore receives less impact. Using the return needle heel 42 for return needles can reduce the collision between the needle plate needle heel 41 and the triangle device, reduce the damage to the needle plate needle heel 41, and increase the service life of the needle 40.

[0160] As attached Figure 2In the specific example shown, the first return needle assembly 20 on the first guide needle head 1 is located between the pressure needle triangle 18 and the first density triangle 14. Specifically, the first return needle assembly 20 includes a first return needle triangle 22 and a first needle blocking triangle 23. The lower end of the first needle blocking triangle 23 has a first needle blocking surface 231, and the upper end of the first return needle triangle 22 has a guide surface and a first return needle surface 221. The guide surface is inclined, and its high end is connected to the first return needle surface 221. The guide surface is used to guide the return needle heel 42 so that it can move stably onto the first return needle surface 221. However, after the return needle heel 42 moves through the guide surface, it will continue to move along the guide surface due to inertia. The needle moves in the tangential direction of the surface, and then the return needle heel 42 will come into contact with the first needle blocking surface 231, thereby preventing the return needle heel 42 from continuing to move along the direction of the guide surface, so that the return needle heel 42 reaches the height of the first return needle surface 221 and moves horizontally along the first return needle surface 221 for a certain distance, so that the knitting needles 40 participating in the knitting can be stably at a consistent height after entering or leaving the knitting area, ensuring the consistency of the knitting loops; wherein the first return needle surface 221 in the first return needle assembly 20 is higher than the highest point of the knitting needle triangle 19, that is, the return needle path is located above the knitting needle triangle 19, thereby reducing the lateral volume of the triangle base plate 10 to a certain extent.

[0161] Specifically, the guide surface includes a first guide surface 222 and a second guide surface 223. The first guide surface 222 is inclined upward, and the second guide surface 223 is inclined downward. The first guide surface 222, the first return needle surface 221, and the second guide surface 223 are connected sequentially from left to right. In use, when the return needle heel 42 moves from left to right or from right to left relative to the first return needle triangle 22, if the height of part of the return needle heel 42 is lower than the height of the first return needle surface 221 due to other factors, its needle heel will be guided by the first guide surface 222 or the second guide surface 223, and then blocked by the first needle blocking surface 231, and finally move to the first return needle surface 221. Then it moves stably along the first return needle surface 221, so that the knitting needles 40 entering or leaving the knitting area are all at the same height, ensuring the consistency of the knitted loops.

[0162] Specifically, the lower end of the first needle-blocking triangle 23 also has a first guide surface 232 and a second guide surface 233. The first guide surface 232 is inclined downward, and the second guide surface 233 is inclined upward. The first guide surface 232, the first needle-blocking surface 231, and the second guide surface 233 are connected sequentially from left to right. Whether the return needle heel 42 moves from left to right or from right to left relative to the first return needle triangle 22, even if, due to other factors, part of the return needle heel 42 is at a height higher than the height of the first return needle surface 221, it can still be guided downward by the first guide surface 232 and the second guide surface 233, thus allowing the return needle heel 42 to stably enter the first return needle path 21, eventually contacting the first return needle surface 221 and moving along it. For example, as... Figure 2 As shown, when the first return needle assembly 20 is located to the left of the first density triangle 14, when the return needle heel 42 moves from left to right relative to the triangle base plate 10, some needles 40 will cause cross-stitching due to inertia, needle groove tightness, and yarn tension. As a result, the height of the return needle heel 42 will be lower or higher than the first return needle surface 221. Thus, the return needle heel 42 will move to the first return needle surface 221 under the guidance of the first guide surface 232 or the first guide surface 222. When the return needle heel 42 moves from right to left relative to the triangle base plate 10, due to the density adjustment of the first density triangle 14, the height of the needles 40 that walk out of the guide needle channel is lower or higher. The height of the return needle heel 42 will be lower or higher than the first return needle surface 221. The return needle heel 42 will move to the first return needle surface 221 under the guidance of the second guide surface 233 or the second guide surface 223.

[0163] Preferably, as shown in the appendix Figure 2 As shown, the tilt angle A of the first guide surface 232 is set to 30-60°, and the tilt angle B of the second guide surface 233 is set to 30-60°. If the tilt angles of the first guide surface 232 and the second guide surface 233 are too small, the first guide surface 232 and the second guide surface 233 are relatively gentle, which provides good protection for the return needle heel 42, but will result in an excessively long overall knitting stroke. If the tilt angles of the first guide surface 232 and the second guide surface 233 are too large, although the overall knitting stroke can be reduced, it will also cause the return needle heel 42 to rise or fall rapidly when the cam device moves quickly along the knitting direction, resulting in a greater lateral impact force, which may easily cause problems such as needle punching and severe wear of the needle heel. Therefore, the tilt angles within the above range can protect the return needle heel 42, ensure its service life, and appropriately shorten the overall knitting stroke. More preferably, the tilt angles of the first guide surface 232 and the second guide surface 233 are set to 45°.

[0164] The structure of the second return needle assembly 30 can vary. In one embodiment, in the attached... Figure 2In the first guide needle head 1 shown, the second return needle assembly 30 includes a second return needle structure disposed on the top surface of the elastic guide triangle 17. When the second density triangle 15 is at its highest point, the height of its top surface is not higher than the height of the second return needle structure, to prevent the return needle heel 42 from impacting the second density triangle 15. The setting principle of the second return needle assembly 30 is the same as that of the first return needle assembly 20. Furthermore, due to the larger space on the right side of the second density triangle 15, the lateral width of the second return needle structure of the second return needle assembly 30 is larger, and the slope is gentler.

[0165] Specifically, the second backstitch structure includes a first needle lifting surface 32, a second backstitch surface 33, and a second needle lifting surface 34. The second backstitch surface 33 is a plane with the same height. Both the first needle lifting surface 32 and the second needle lifting surface 34 have a high end and a low end. The high end of the first needle lifting surface 32 and the high end of the second needle lifting surface 34 are respectively connected to the two ends of the second backstitch surface 33. The height of the second backstitch surface 33 is the same as the height of the first backstitch surface 221. Due to the setting of the first needle lifting surface 32 and the second needle lifting surface 34, no matter whether the first needle guide head 1 moves along the first knitting direction or along the second knitting direction, it will be guided to the second backstitch surface 33, thereby ensuring that the backstitch height is consistent.

[0166] Preferably, as shown in the appendix Figure 2 As shown, the angle C between the line connecting the high and low ends of the first lifting surface 32 and the second return surface 33 ranges from 15 to 40°, and the angle D between the line connecting the high and low ends of the second lifting surface 34 and the second return surface 33 ranges from 15 to 40°. Within this angle range, the slopes of the first lifting surface 32 and the second lifting surface 34 are relatively gentle, preventing the return needle heel 42 from having excessive inertia after the first lifting surface 32 or the second lifting surface 34 has moved, which could lead to a large skipped needle amplitude. Accordingly, the first lifting surface 32 can be a sloping surface or an arc surface. In this embodiment, the angle C between the line connecting the high and low ends of the first lifting surface 32 and the second return structure is 20°, and the angle D between the line connecting the high and low ends of the second lifting surface 34 and the second return structure is 20°. The first lifting surface 32 and the second lifting surface 34 are arc surfaces, which can play a certain buffering role.

[0167] In this embodiment, no needle-blocking component is provided. To prevent the return needle heel 42 from continuing to rise along the tangential direction of the first needle-lifting surface 32 or the second needle-lifting surface 34, the vertical distance L between the lower edge of the elastic guide triangle 17 and the second return needle surface 33 is approximately equal to the distance between the return needle heel 42 and the needle-lifting plate heel 41. The difference in distance is 1-1.5mm, which can prevent the needle 40 from having excessively large up-and-down needle movement during operation, while also leaving a margin to ensure stable operation of the needle 40. Thus, when the return needle heel 42 continues to rise along the tangential direction of the first needle-lifting surface 32 or the second needle-lifting surface 34, the needle-lifting plate heel 41 abuts against the lower edge of the elastic guide triangle 17, pulling the return needle heel 42 back into the second return needle path 31. In a specific example, the distance between the back needle heel 42 and the needle tip heel 41 is 22mm, and the vertical distance L between the lower edge of the elastic guide triangle 17 and the second back needle surface 33 is 20.5-21mm.

[0168] Another structure of the second return needle assembly 30 is shown in the appendix. Figure 4 In a specific example, the second backstitch assembly 30 includes a second backstitch structure disposed on the top surface of the elastic guide triangle 17 and a second needle-blocking triangle 35 disposed above the second backstitch structure. At this time, since the second backstitch assembly 30 is disposed between the second density triangle 15 and the presser triangle 18, the space is small, the lateral length of the second backstitch structure is small, and the slope is large. Therefore, it is necessary to set the second needle-blocking triangle 35 to prevent the knitting needle 40 from skipping stitches. The function of the second needle-blocking triangle 35 is the same as that of the first needle-blocking triangle 23, and the structure is also basically the same, so it will not be described in detail here.

[0169] The second guide surface 223 and the first lifting surface 32 in the first return needle assembly 20 and the second return needle assembly 30 are arranged opposite each other, and the first guide surface 222 and the second lifting surface 34 are arranged opposite to each other. In this embodiment, the distance between the first return needle assembly 20 and the second return needle assembly 30 and the first density triangle 14 or the elastic band guide triangle 17 is shortened, so that the distance between the first return needle path 21 and the second return needle path 31 and the exit of the guide needle channel is shortened or even partially overlapped. This may cause the needle heel 41 of the needle ejector piece to be guided back by the return needle assembly before it has left the guide needle channel, and thus the needle heel 41 of the needle ejector piece collides with the first density triangle 14 or the second density triangle 15. Therefore, in the first return needle assembly 20 and the second return needle assembly 30, the second guide surface 223 and the first lifting surface 32 are arranged opposite to each other, and the first guide surface 222 and the second lifting surface 34 are arranged opposite to each other. The lower end of the second guide surface 223 and the first needle lifting surface 32 of the double-back needle assembly 30 is provided with a concave surface 24. The concave surface 24 corresponds to the exit of the guide needle channel when the first density triangle 14 or the second density triangle 15 is at its lowest point. The concave surface 24 is lower than the lower end of the second guide surface 223 and the first needle lifting surface 32, so that when the needle heel 41 of the needle lifter moves down along the guide needle surface of the first density triangle 14 or the second density triangle 15 out of the guide needle channel and forms a loop, the upper back needle heel 42 is located in the concave surface 24, avoiding collision between the back needle heel 42 and the first back needle assembly 20 or the second back needle assembly 30. The needle 40 can return to its position along the first back needle assembly 20 or the second back needle assembly 30 after the yarn has formed a loop. See attached. Figure 2 As shown, in this embodiment, the first return needle assembly 20 is located to the left of the first density triangle 14, and the second return needle assembly 30 is located to the right of the second density triangle 15, so that the concave surface 24 is located at the lower end of the second guide surface 223 and the first needle lifting surface 32.

[0170] As attached Figure 3 and attached Figure 5 As shown, the triangular device in this embodiment also includes a triangular control mechanism disposed on the other end face of the triangular base plate 10. To simplify the structure, this embodiment links multiple triangular devices together to reduce the number of control mechanisms. Specifically, the triangular control mechanism includes a first control component 50 that links and controls the first needle-starting triangular device 12 and the middle triangular device 11, a second control component 60 that links and controls the first density triangular device 14 and the pressing triangular device 18, and a third control component 70 that links and controls the second density triangular device 15 and the elastic band triangular device 16.

[0171] In order to achieve independent control of the first needle guide head 1 and the second needle guide head 2, the first needle guide head 1 in this embodiment is provided with a triangular control mechanism, and the second needle guide head 2 is provided with another triangular control mechanism. Thus, each triangle of the first needle guide head 1 and the second needle guide head 2 can move independently, and the first needle guide head 1 and the second needle guide head 2 have different knitting patterns, thereby cooperating to achieve more knitting methods.

[0172] Since the positions of the pressure triangles 18 on the first needle guide head 1 and the second needle guide head 2 are different, the triangle control mechanisms are also somewhat different. In this embodiment, the common parts of the two triangle control mechanisms are described first, taking the first needle guide head 1 as an example.

[0173] For details, see attached. Figure 3 As shown, the first starting triangle 12 includes a first pin 121 located on the back and penetrating the triangle base plate 10. The first control assembly 50 includes a first starting push foot 51, which is rotatably connected to the back of the triangle base plate 10. The first starting push foot 51 has a first inclined surface 511 at one end near the first pin 121. The first pin 121 includes a first abutment portion 122 that can extend onto the first starting push foot 51.

[0174] The first needle-starting foot 51 rotates, allowing the first inclined surface 511 to be inserted between the first abutment 122 and the back of the triangular base plate 10, and pushing the first abutment 122 to the highest point of the first needle-starting foot 51, so that the first needle-starting triangle 12 is in a flush position.

[0175] The first needle-starting foot 51 is also provided with a first pusher 512. The first pusher 512 is rotatably connected to the first needle-starting foot 51. When the first pusher 512 is pushed by an external force, it drives the first needle-starting foot 51 to rotate. The first inclined surface 511 can be inserted between the first abutting part 122 and the back of the triangular base plate 10, so that the first abutting part 122 moves to the highest point of the first inclined surface 511, and the first needle-starting triangle 12 is in a flush position, with its front side flush with the front side of the triangular base plate 10.

[0176] In a preferred embodiment, the first starting triangle 12 and the middle triangle 11 are linked. Specifically, the middle triangle 11 includes a second pin 111 located on the back and penetrating the triangle base plate 10. The first control component 50 includes a half-needle push foot 52. The half-needle push foot 52 is rotatably connected to the back of the triangle base plate 10. A second pushing member 521 is provided on the half-needle push foot 52. The second pushing member 521 is pushed by an external force, thereby driving the half-needle push foot 52 to rotate. The half-needle push foot 52 has a second inclined surface 522 and a first high surface 523 at one end near the second pin 111. The second pin 111 includes a second abutment portion 112 that can extend to the half-needle push foot 52. When the half-needle push foot 52 rotates, such that when the second abutment portion 112 is tangent to or separate from the second inclined surface 522, the middle triangle 11 is in the full height position. When the second abutment portion 112 contacts the first high surface 523, the middle triangle 11 is in the half-height position.

[0177] To achieve the linkage between the first starting triangle 12 and the middle triangle 11, more structures need to be provided on the half-needle pusher foot 52. Specifically, the half-needle pusher foot 52 also includes a third inclined surface 524 and a first concave surface 525. The second inclined surface 522 and the third inclined surface 524 are arranged opposite to each other. The first high surface 523 is connected to the highest point of the second inclined surface 522 and the highest point of the third inclined surface 524 to form a first boss. The lowest point of the third inclined surface 524 is connected to the first concave surface 525 to form a first groove. When the second abutment part 112 is located in the first groove, the middle triangle 11 is located at full height. When the second abutment part 112 is located in the first boss, the middle triangle 11 is located at half height.

[0178] The rotation of the first needle pusher foot 51 is achieved by the first pusher member 512 being lifted or lowered under the action of an external force, and the rotation of the half needle pusher foot 52 is achieved by the second pusher member 521 being lifted or lowered under the action of an external force. Therefore, the first pusher member 512 and the second pusher member 521 will contact components other than the triangular device (such as the push rod mentioned below). Since the triangular device will reciprocate in the glove machine, the first pusher member 512 and the second pusher member 521 can be bearings or rollers to reduce the friction between the first pusher member 512 and the second pusher member 521 and the corresponding push rod when the first needle guide head 1 and the second needle guide head 2 are reciprocating.

[0179] Therefore, the first needle guide head 1 has the following state: when the first pusher 512 and the second pusher 521 are not pushed up, the first needle pusher foot 51 and the half-needle pusher foot 52 are in the initial position, as shown in the attached figure. Figure 3 As shown, when the first abutting part 122 separates from the first inclined surface 511, and the second abutting part 112 is tangent to or separate from the second inclined surface 522, the first starting needle triangle 12 is at full height, and the middle triangle 11 is at full height, corresponding to a bidirectional full-needle knitting pattern; when the first pusher 512 and the second pusher 521 are pushed up to a first set height (corresponding to the second drive position of the first drive assembly 80), the first starting needle pusher foot 51 rotates at a certain angle, the first abutting part 122 is tangent to or separate from the first inclined surface 511, the half-needle pusher foot 52 rotates at a certain angle, and when the second abutting part 112 abuts against the first high surface 523, the first starting needle triangle 12 is at full height. At the high position, the middle triangle 11 is at half-height, corresponding to the bidirectional hanging stitch knitting mode; when the first pusher 512 and the second pusher 521 are pushed up to the second set height (corresponding to the first drive position of the first drive assembly 80), the first needle pusher 51 continues to rotate at a certain angle, the first abutting part 122 abuts against the highest point of the first needle pusher 51, the half-needle pusher 52 continues to rotate at a certain angle, when the second abutting part 112 abuts against the first concave surface 525, the front of the first needle pusher triangle 12 is flush with the front of the triangle base plate 10, and the middle triangle 11 is at full height, corresponding to the unidirectional full stitch knitting mode in which the first needle pusher triangle 12 does not participate in knitting.

[0180] Since the first control component 50, the first needle-starting triangle 12, and the middle triangle 11 are not powered themselves, they require external force from the first drive component 80 or the needle heel. Therefore, a first return spring 123 is provided between the first pin 121 and the back of the triangle base plate 10 to tend to reset the first needle-starting triangle 12 from the flush position to the full height position. This spring 123 is used to reset the first needle-starting triangle 12 from the flush position to the full height position after the external force is lost. Figure 23 As shown; the first needle-starting foot 51 in the first control assembly 50 is also unpowered. Therefore, a second return spring 513 is connected to the back of the triangular base plate 10, which tends to return the first needle-starting foot 51 to its initial position, as shown in the attached figure. Figure 3 As shown, this is used to pull the first inclined surface 511 away from the first abutting part 122 after the first pushing member 512 loses its external pushing force. Similarly, the half-needle push foot 52 also needs to be reset. The initial position of the half-needle push foot 52 is the position when the third abutting part 162 is tangent to or separated from the third inclined surface 524; a fourth return spring 526 is connected between the half-needle push foot 52 and the back of the triangular base plate 10, which tends to make the half-needle push foot 52 return to its initial position. When the external pushing force on the half-needle push foot 52 disappears, the half-needle push foot 52 rotates to its initial position under the action of the fourth return spring 526; while the second A third return spring 113 is provided between the pin 111 and the back of the triangular base plate 10, which tends to reset the middle triangle 11 from the half-height position to the full-height position. When the half-pin push foot 52 rotates back to the initial position, or when the second abutment part 112 corresponds to the first groove, the third pin 161 moves closer to the back of the triangular base plate 10 under the action of the second return spring 513, and the second abutment part 112 abuts against the first concave surface 525, and the middle triangle 11 resets from the half-height position to the full-height position.

[0181] As attached Figure 3 and attached Figure 5 As shown, in order to achieve the linkage between the first density triangle 14 and the pressure needle triangle 18, the back of the triangle base plate 10 is provided with a first sliding seat 103 connected to the first density triangle 14 for driving the first density triangle 14 to move along the through inclined groove 101. A second sliding seat 104 is also provided connected to the pressure needle triangle 18 for driving the pressure needle triangle 18 to move along the pressure needle slide groove 102. The second control component 60 includes a first density push foot 61 and a third connecting rod 62. One end of the first density push foot 61 is rotatably connected to the triangle base plate 10, and the other end is rotatably connected to the first sliding seat 103. One end of the third connecting rod 62 is rotatably connected to the first density push foot 61, and the other end is rotatably connected to the second sliding seat 104.

[0182] The first density push foot 61 is provided with a third push member 611. The rotation of the first density push foot 61 is achieved by the third push member 611 rising or falling under the action of an external force. Therefore, the third push member 611 will contact components other than the triangular device (such as the push rod mentioned below). Since the triangular device will reciprocate in the glove machine, the third push member 611 can be a bearing or a roller to reduce the friction between the third push member 611 and the corresponding push rod when the first needle guide head 1 and the second needle guide head 2 are reciprocating.

[0183] The main difference between the first control component 50 on the first needle guide head 1 and the second needle guide head 2 lies in the structure of the connecting rod that drives the second sliding seat 104, as shown in the attached figure. Figure 3 In the first needle guide head 1 shown, the pressure needle triangle 18 and the first density triangle 14 are on the same side of the triangle base plate 10 and are relatively close. Therefore, the length of the third connecting rod 62 is relatively short, and it is bent. The pivot is located at the bend. When one end of the third connecting rod 62 connected to the first density push foot 61 rises, the other end falls, thereby driving the pressure needle triangle 18 to fall; as shown in the attached... Figure 5 In the second guide needle head 2 shown, the pressure needle triangle 18 and the first density triangle 14 are located on both sides of the triangle base plate 10 and are far apart. Therefore, the third connecting rod 62 is relatively long and is a seesaw type. One end can abut against the top of the first sliding seat 103, and the other end is connected to the second sliding seat 104. The first density push foot 61 drives the first sliding seat 103 to move upward. The top of the first sliding seat 103 abuts against one end of the connecting rod, and the other end of the third connecting rod 62 descends, thereby driving the second sliding seat 104 and the pressure needle triangle 18 to descend.

[0184] The first density triangle 14 and the pressure needle triangle 18 are not powered by themselves. Therefore, the back of the first sliding seat 103 and the triangle base plate 10 are provided with a fifth return spring 105 that tends to return the first sliding seat 103 to its initial position. The initial position of the first sliding seat 103 is when the first density triangle 14 is at the bottom of the through groove 101. The back of the second sliding seat 104 and the triangle base plate 10 are provided with a sixth return spring 106 that tends to return the second sliding seat 104 to its initial position. The initial position of the second sliding seat 104 is when the pressure needle triangle 18 is at the top of the pressure needle groove 102.

[0185] There are many ways to move the elastic band triangle 16 to the flush position and half-height position. For example, a cylinder can be installed on the back of the elastic band triangle 16 to drive it. However, due to the compact internal structure and limited space of the braiding equipment, and the fact that the triangle device should not be too heavy as this would affect its reciprocating braiding motion, the preferred method is as follows (see attached diagram). Figure 8As shown, in this embodiment, both the second density triangle 15 and the elastic band triangle 16 are controlled by the third control component 70. Considering that the second density triangle 15 needs to move along the through groove on the triangle base plate 10, and the elastic band triangle 16 moves along the thickness direction of the triangle base plate 10, the back of the triangle base plate 10 is provided with a third sliding seat 107 connected to the second density triangle 15 to drive the second density triangle 15 to move along the through groove. The end of the third sliding seat 107 near the mounting base 109 is connected to a pressure block 72 with a fourth inclined surface 721. The third sliding seat 107 and the pressure block 72 can be an integral structure or fixedly installed, as shown in the attached figure. Figure 9 As shown.

[0186] As attached Figure 8 As shown, a mounting base 109 is fixed to the back of the triangular base plate 10. Its function is to mount the elastic triangle 16, ensuring its stable placement in the corresponding through groove of the triangular base plate 10. A third pin 161 protrudes from the mounting base 109 on the back of the elastic triangle 16. The axial direction of the third pin 161 is perpendicular to the back of the triangular base plate 10. A third abutment portion 162 extends from the side of the third pin 161, and its extension direction is parallel to the radial direction of the third pin 161. The third abutment portion 162 can move along the surface of the pressure block 72. Specifically, when the third sliding seat 107 moves away from the mounting base 109, the third abutment portion 162 moves from a high position to a low position on the fourth inclined surface 721, and the elastic triangle 16 moves from a flush position to a half-height position; when the third sliding seat 107 moves closer to the mounting base 109, the third abutment portion 162 moves from a low position to a high position on the fourth inclined surface 721, and the elastic triangle 16 moves from a half-height position to a flush position.

[0187] This embodiment can also be modified by setting the height length of the pressure block 72, the length and angle of the fourth inclined surface 721, so that the second density triangle 15 moves upward a certain distance from its initial position, the third abutment part 162 remains on the height surface of the pressure block 72, the elastic band triangle 16 remains in the flush position, and the fourth inclined surface 721 is shorter and has a larger angle, so that the third abutment part 162 can quickly move from the low position to the high position or from the high position to the low position of the fourth inclined surface 721, realizing the rapid switching of the elastic band triangle 16 between the flush position and the half-height position; the advantage of this setting is that, on the one hand, the second density triangle 15 can maintain its original function and realize the degree adjustment, when the elastic band triangle 16 is in the flush position The second density triangle 15 can normally adjust the gauge of the second starting triangle 13. When the elastic band triangle 16 is in the half-height position, the second density triangle 15 can adjust the gauge of the elastic band guide triangle 17. On the other hand, when the second density triangle 15 moves upward to a certain position, the elastic band triangle 16 can be raised to the half-height position. When knitting with elastic band, the needle heel first rises to a certain height along the elastic band triangle 16, and then descends into the space between the second density triangle 15 and the second starting triangle 13. After the second density triangle 15 moves upward, the descent of the needle heel can be shortened, which shortens the overall travel of the needle heel, improves knitting efficiency, and also helps to maintain the stability of the needle heel and improves the knitting quality.

[0188] To simplify the triangular control mechanism and reduce the power source, this embodiment uses an elastic element to reset the rubber band triangle 16 and the second density triangle 15. Specifically, see attached... Figure 3 As shown, a seventh return spring 108 is connected to the third sliding seat 107, which tends to return the third sliding seat 107 to its initial position. The initial position of the third sliding seat 107 is the position when the second density triangle 15 is located at the lowest end of the through-slot 101. The seventh return spring 108 can connect the third sliding seat 107 and the triangular base plate 10, or it can connect the third sliding seat 107 and the mounting base 109. When the third sliding seat 107 is pushed away from the mounting base 109 by an external force, the seventh return spring 108 is stretched. When the external force disappears, the third sliding seat 107 moves closer to the mounting base 109 under the pull of the seventh return spring 108. (See attached...) Figure 18 As shown, an eighth return spring 163 is provided between the elastic band triangle 16 and the mounting base 109, which tends to push the elastic band triangle 16 from the flush position to the half-height position. When the third abutment part 162 is in the high position of the pressure block 72, the eighth return spring 163 is in the compressed state. When the third abutment part 162 moves from the high position of the fourth inclined surface 721 to the low position, the eighth return spring 163 pushes the elastic band triangle 16 from the flush position to the half-height position.

[0189] The third control component 70 includes a second density push foot 71, on which a fourth push member 711 is provided. One end of the second density push foot 71 is rotatably connected to the triangular base plate 10, and the other end is connected to the pressure block 72 or the third sliding seat 107. Under the action of the fourth push member 711, the second density push foot 71 rotates relative to the triangular base plate 10 to drive the third sliding seat 107 to move closer to or away from the mounting base 109. Specifically, the second density push foot 71 includes a first connecting rod 712 with a fourth push member 711 and a second connecting rod 713 connecting the pressure block 72. A rotating shaft is fixed to the back of the triangular base plate 10. One end of the first connecting rod 712 is rotatably connected to the rotating shaft, and the other end is rotatably connected to the second connecting rod 713. The other end of the second connecting rod 713 is rotatably connected to the pressure block 72. The first connecting rod 712 is bent and protrudes towards the bottom of the triangular base plate 10. The fourth push member 711 is located at the bend. Thus, when the fourth push member 711 is subjected to an upward force, it drives the first connecting rod 712 to rotate and pushes the second connecting rod 713 upward. The second connecting rod 713 drives the pressure block 72 and the third sliding seat 107 to move upward away from the mounting base 109. When the force on the fourth push member 711 disappears, the seventh return spring 108 drives the pressure block 72 and the third sliding seat 107 to return to their original positions. The first connecting rod 712, the second connecting rod 713, and the fourth push member 711 are all driven to return to their original positions.

[0190] Since the first needle guide head 1 and the second needle guide head 2 need to move back and forth along the knitting direction, the fourth pusher 711 is rotatably connected to the second density pusher foot 71, and can be a bearing or a roller to reduce the friction between the fourth pusher 711 and other drive mechanisms.

[0191] As attached Figure 10 As shown, the elastic band triangle 16 in this embodiment also includes a body 164 and a triangular portion 165 protruding from the front of the body 164. A third pin 161 is disposed on the back of the body 164. The triangular portion 165 includes a needle-feeding sidewall 167 facing the elastic band guide triangle 17. The body 164 includes an outer edge portion 166 that protrudes from the needle-feeding sidewall 167 facing the elastic band guide triangle 17. The reason for the formation of the outer edge portion 166 is that, in the initial stage of processing, the elastic band triangle 16 is made into a blank with the largest size, and then the triangular portion 165 is cut as needed. Therefore, the side dimension of the outer edge portion 166 is the original size of the blank. It should be noted that the triangular portion 165 of the largest size elastic band triangle 16 is the original size of the blank, and there is no outer edge portion 166. With this structure, all elastic band triangles 16 use the same blank in the initial stage of processing, reducing the number of molds and reducing processing costs.

[0192] As attached Figure 10As shown, the elastic band triangle 16 also includes a limiting block 168, which is protruding from the bottom of the body 164 and can abut against the back of the triangle base plate 10 when the elastic band triangle 16 is in a half-height position, so as to limit the height of the elastic band triangle 16 protruding from the front of the triangle base plate 10.

[0193] In the previous text, it was described that the heel of the 40-stitch needle corresponding to the elastic band rises along the starting face of the elastic band triangle 16, reaches the apex of the elastic band triangle 16, and then descends along the second density triangle 15. For details, please refer to the attached document. Figure 4 As shown, the second density triangle 15 includes a first guide block 151 extending from the side towards the elastic band guide triangle 17. When the elastic band triangle 16 is in the half-height position, the front of the triangle portion 165 protrudes from the front of the triangle base plate 10, and the outer edge portion 166 is flush with the front of the triangle base plate 10. The needle-running sidewall 167, the sidewall of the elastic band guide triangle 17, and the first guide block 151 form an elastic band needle-running groove. The first guide block 151 can limit the height of the knitting needle 40 corresponding to the elastic band, and is used to adjust the height of the elastic band needle-running. If the height of the elastic band needle-running is too high... If the height of the elastic band is too high or too low, the elastic band will collide with the pin of the sinker when it is inserted, which increases the probability of the elastic band breaking. It may also cause the sinker to be unable to insert the elastic band, the yarn loop to be unable to loop the elastic band, and the elastic band weaving failure. By moving the position of the second density triangle 15 in the through groove, the distance between the first guide block 151 and the elastic band triangle 16 changes, thereby changing the height of the knitting needle 40 corresponding to the elastic band, so that the elastic band can be precisely matched with the insertion port of the sinker, and the elastic band weaving effect is better.

[0194] As attached Figure 4 As shown, the elastic band guide triangle 17 is fixed to the front of the triangular base plate 10. Another function of the elastic band guide triangle 17 is to stabilize the second density triangle 15, forming a seamless needle guide channel and preventing the needle heel from getting stuck in the second density triangle 15 and the elastic band guide triangle 17. Specifically, the inclination angle of the side of the elastic band guide triangle 17 is consistent with the inclination angle of the through groove. The second density triangle 15 includes a first guide block 151 extending towards the elastic band guide triangle 17 on the side. The first guide block 151 abuts against the side of the elastic band guide triangle 17. The elastic band guide triangle 17 includes a first guide block 151 extending towards the elastic band guide triangle 17 on the side. The second guide block 171 extends towards the second density triangle 15 and abuts against the side of the second density triangle 15. There is a space between the first guide block 151 and the second guide block 171, so that when the second density triangle 15 moves upward, the first guide block 151 and the second guide block 171 will not interfere with each other. During the movement, the second density triangle 15 abuts against the side wall of the elastic band guide triangle 17, which improves the stability of the second density triangle 15 in the through inclined groove 101, thereby ensuring that the elastic band triangle 16 can be stably lifted from the flush position to the half-height position.

[0195] This invention also discloses a glove machine, comprising two needle beds (not shown) spaced apart along the knitting direction and at least two yarn feeders (not shown) positioned above the needle beds. It also includes the cam devices described in the above embodiments, one cam device corresponding to one needle bed and the other corresponding to the other needle bed. Each cam device can reciprocate along the same knitting direction on the needle bed, cooperating with at least one yarn feeder for knitting. Below the needle beds is a cam control drive mechanism corresponding to the cam control mechanism in the cam device. Each cam device is equipped with one cam control drive mechanism, thereby enabling independent control of the first needle guide head 1 and the second needle guide head 2. Based on the multiple knitting modes of each cam device, the glove machine can achieve multiple knitting methods through the cooperation of the two cam devices and the yarn feeders.

[0196] Based on this, the present invention also discloses a knitting method using the glove machine of the above embodiment, wherein the first guide needle head 1 and the second guide needle head 2 both have a bidirectional full-mesh knitting mode, a bidirectional hanging mesh knitting mode, a unidirectional elastic band knitting mode, a unidirectional full-mesh knitting mode, a unidirectional hanging mesh knitting mode, and a mesh adjustment knitting mode. Specifically, the knitting method includes the following steps:

[0197] Two-way full-eye knitting mode: control the first starting triangle 12 to be in the full height position, the second starting triangle 13 to be in the full height position, control the middle triangle 11 to be in the full height position, and control the elastic triangle 16 to be in the flush position.

[0198] Two-way drop stitch knitting mode: control the first starting triangle 12 to be at full height, the second starting triangle 13 to be at full height, control the middle triangle 11 to be at half height, and control the elastic triangle 16 to be at the same level.

[0199] One-way elastic band knitting mode: control the first starting triangle 12 to be at full height, the second starting triangle 13 to be at full height, control the middle triangle 11 to be at full height, and control the elastic band triangle 16 to be at half height.

[0200] One-way full-eye knitting mode: control the first starting triangle 12 to be at the same level, the second starting triangle 13 to be at full height, control the middle triangle 11 to be at full height, and control the elastic triangle 16 to be at the same level.

[0201] One-way drop stitch knitting mode: control the first starting triangle 12 to be at the same level, the second starting triangle 13 to be at full height, control the middle triangle 11 to be at half height, and control the elastic triangle 16 to be at the same level.

[0202] Adjustable weaving mode: Based on the two-way full-mesh weaving mode, two-way hanging mesh weaving mode or one-way weaving mode, control the first density triangle 14 or the second density triangle 15 to move a set distance along the through oblique groove 101 on the triangle base plate 10.

[0203] Users can set the weaving pattern of each triangle at a certain point in time according to their own needs, thereby realizing a variety of weaving methods.

[0204] Specifically, when both the first needle head 1 and the second needle head 2 are in bidirectional full-mesh knitting mode, the first needle head 1 performs reciprocating knitting motion on a needle bed with a corresponding yarn feeder. At the same time, the second needle head 2 is offset from the first needle head 1 in the same direction and performs reciprocating knitting motion with another yarn feeder on another needle bed. The first needle head 1 independently knits the first side of the glove, and the second needle head 2 independently knits the second side of the glove. Then, the edges of the first and second sides meet at the junction, connecting the sides of the first and second sides together. The offset in the same direction refers to the offset of the highest point of the middle triangle 11 in the first needle head 1 and the second needle head 2, so that the knitting needles 40 in the corresponding needle beds extend one after another.

[0205] When both the first needle head 1 and the second needle head 2 are in bidirectional full-mesh knitting mode and are making synchronous unidirectional knitting movements along the same knitting direction, one of the yarn feeders will simultaneously cooperate with the first needle head 1 and the second needle head 2 to realize the seam knitting along the first knitting direction or the second knitting direction. The synchronous state means that the first needle head 1 and the second needle head 2 respectively control the knitting needles 40 in the corresponding needle beds to extend and hook the same strand of yarn. The first needle head 1 and the second needle head 2 sew the ends of the first and second sides of the glove together.

[0206] When both the first needle head 1 and the second needle head 2 are in bidirectional hanging knitting mode, the first needle head 1 performs reciprocating knitting motion on a needle bed with a corresponding yarn feeder. At the same time, the second needle head 2 is offset from the first needle head 1 in the same direction and performs reciprocating knitting motion on another needle bed with another yarn feeder. The first needle head 1 independently knits the first side of the glove, and the second needle head 2 independently knits the second side of the glove. Then, the edges of the first and second sides are joined together, connecting the sides of the first and second sides together. Both the first and second sides are knitted with hanging knitting.

[0207] When the first needle head 1 is in bidirectional hanging mesh knitting mode and the second needle head 2 is in bidirectional full mesh knitting mode, the first needle head 1 performs reciprocating knitting motion on a needle bed with a corresponding yarn feeder. At the same time, the second needle head 2 is offset from the first needle head 1 in the same direction and performs reciprocating knitting motion on another needle bed with another yarn feeder. The first needle head 1 independently knits the first side of the glove, and the second needle head 2 independently knits the second side of the glove. Then, the edges of the first and second sides are joined together, connecting the sides of the first and second sides. The first side is knitted with hanging mesh, and the second side is knitted with full mesh.

[0208] When the second guide needle head 2 is in the bidirectional hanging mesh knitting mode and the first guide needle head 1 is in the bidirectional full mesh knitting mode, the first guide needle head 1 performs reciprocating knitting motion on a needle bed with a corresponding yarn feeder. At the same time, the second guide needle head 2 is offset from the first guide needle head 1 in the same direction and performs reciprocating knitting motion on another needle bed with another yarn feeder. The first guide needle head 1 independently knits the first side of the glove, and the second guide needle head 2 independently knits the second side of the glove. Then, the edges of the first side and the second side are joined together, connecting the sides of the first side and the second side together. The second side is knitted with hanging mesh, and the first side is knitted with full mesh.

[0209] In this embodiment, the unidirectional elastic band knitting mode of the first guide needle head 1 and the second guide needle head 2 can be combined with the bidirectional full-mesh knitting mode or the bidirectional hanging-mesh knitting mode. An elastic band yarn feeder is also added. In the first knitting direction, one yarn feeder and the elastic band yarn feeder cooperate with the second guide needle head 2, with the elastic band triangle 16 on the second guide needle head 2 at a half-height position. On the second side, the elastic band is woven in first, followed by the yarn. The first guide needle head 1 cooperates with another yarn feeder to knit the first side. In the second knitting direction, one yarn feeder and the elastic band yarn feeder cooperate with the first guide needle head 1, with the elastic band triangle 16 on the first guide needle head 1 at a half-height position. On the first side, the elastic band is woven in first, followed by the yarn. The second guide needle head 2 cooperates with another yarn feeder to knit the second side, thus achieving unidirectional elastic band knitting. Elastic band knitting is generally used in the cuffs of gloves and is usually used in conjunction with hanging-mesh knitting.

[0210] When both the first guide needle head 1 and the second guide needle head 2 are in unidirectional full-mesh knitting mode, in the first knitting direction, the first guide needle head 1 works with the yarn feeder to knit the first side, while the second guide needle head 2 runs idle. In the second knitting direction, the second guide needle head 2 works with the yarn feeder to knit the second side, while the first guide needle head 1 runs idle. This is a conventional spiral knitting method. The unidirectional hanging-mesh knitting mode is basically the same and is a conventional knitting method, which will not be described in detail here.

[0211] Based on the above knitting method, the first guide needle head 1 and the second guide needle head 2 can also adjust the knitting mode by adjusting the mesh size: based on the bidirectional full mesh knitting mode, bidirectional hanging mesh knitting mode or unidirectional knitting mode, the first density triangle 14 or the second density triangle 15 is controlled to move a set distance along the through oblique groove 101 on the triangle base plate 10.

[0212] To achieve control of the triangles in each triangle device, the triangle control mechanism includes a first control component 50 for linkage control of the first starting triangle 12 and the middle triangle 11, a second control component 60 for linkage control of the first density triangle 14 and the pressing triangle 18, and a third control component 70 for linkage control of the second density triangle 15 and the elastic band triangle 16; as shown in the attached diagram. Figure 11 and attached Figure 12 As shown, the triangular control drive mechanism includes a first drive component 80 and a second drive component 90. The first drive component 80 is drive-connected to the first control component 50 and the third control component 70; the second drive component 90 is drive-connected to the second control component 60.

[0213] As attached Figure 17 As shown, the first drive assembly 80 includes a first motor 81, a first push rod 84, a second push rod 85, a first cam 82, and a second cam 83. The first motor 81 drives the first cam 82 to rotate, so that the first push rod 84 has a first rest position and at least one drive position. When the first push rod 84 is in the drive position, it can drive the first needle push foot 51 and the half needle push foot 52 of the first control assembly 50. The first motor 81 drives the second cam 83 to rotate, so that the second push rod 85 has a second rest position and at least one drive range. When the second push rod 85 is in the drive range, it can drive the first density push foot 61 of the second control assembly 60.

[0214] The drive positions of the first push rod 84 include a first drive position and a second drive position.

[0215] As attached Figure 22 and attached Figure 23 As shown, when the first push rod 84 is in the first rest position, it contacts the first start-up push foot 51 and the half-needle push foot 52 and puts the first start-up push foot 51 and the half-needle push foot 52 in the initial position, the first start-up triangle 12 is in the full height position, and the middle triangle 11 is in the full height position.

[0216] As attached Figure 20 and attached Figure 21 As shown, when the first push rod 84 is in the first driving position, it pushes the first needle-starting push foot 51 and the half-needle push foot 52, and brings the first needle-starting push foot 51 close to the first abutting part 122. The first high surface 523 of the half-needle push foot 52 abuts against the second abutting part 112. The first needle-starting triangle 12 is in the full height position, and the middle triangle 11 is in the half height position.

[0217] As attached Figure 17 and attached Figure 18 As shown, when the first push rod 84 is in the second driving position, it pushes the first needle-starting push foot 51 and the half-needle push foot 52, and makes the high surface of the first needle-starting push foot 51 abut against the first abutting part 122, and the first concave surface 525 of the half-needle push foot 52 abut against the second abutting part 112. The first needle-starting triangle 12 is in the flush position, and the middle triangle 11 is in the full height position.

[0218] As attached Figure 13 and attached Figure 14 As shown, the first cam 82 is provided with a first curved groove 821 that enables the first push rod 84 to reach the first rest position, the first drive position and the second drive position;

[0219] The first push rod 84 is provided with a first inclined groove 842 and a first protrusion 841. The central axis of the first cam 82 passes through the first inclined groove 842 and the first protrusion 841 is placed in the first curved groove 821. The first motor 81 rotates to make the first protrusion 841 move along the first curved groove 821 to change the relative position of the first protrusion 841 and the central axis of the first cam 82, thereby driving the first push rod 84 to move between the first rest position, the first driving position and the second driving position.

[0220] The driving range of the second push rod 85 includes the first driving range and the second driving range, as shown in the attached figure. Figure 22 As shown, when the second push rod 85 is in the second rest position, it contacts the first density push foot 61 and puts the first density push foot 61 in the initial position, while the first density triangle 14 and the pressure needle triangle 18 are in their original positions.

[0221] As attached Figure 19 As shown, when the second push rod 85 is in the first driving range, it pushes the first density push foot 61, the first density triangle 14 moves along the through inclined groove 101, and the pressure needle triangle 18 moves in the non-working range.

[0222] As attached Figure 24 As shown, when the second push rod 85 is in the second driving range, it pushes the first density push foot 61, the first density triangle 14 moves along the through inclined groove 101, and the pressure needle triangle 18 moves within the working range.

[0223] As attached Figure 15 and attached Figure 16As shown, the second cam 83 is provided with a second curved groove 831 that enables the second push rod 85 to reach the second rest position, the first driving range, and the second driving range. The second push rod 85 is provided with a second inclined groove 852 and a second protrusion 851. The central axis of the second cam 83 passes through the second inclined groove 852 and the second protrusion 851 is placed in the second curved groove 831. The first motor 81 rotates to make the second protrusion 851 move along the second curved groove 831 to change the relative position of the second protrusion 851 and the central axis of the second cam 83, thereby driving the second push rod 85 to move between the second rest position, the first driving range, and the second driving range.

[0224] As attached Figure 17 As shown, the first curved groove 821 has a first alignment hole 822 at its starting end, and the second curved groove 831 has a second alignment hole 832 at its starting end. The line connecting the center of the first alignment hole 822 and the center of the first cam 82 and the line connecting the center of the second alignment hole 832 and the center of the second cam 83 are collinear.

[0225] The first curved groove 821 includes curved segments a1, a2, a3, a4, and a5 connected sequentially from the starting end to the ending end. The second curved groove 831 includes curved segments b1, b2, b3, b4, and b5 connected sequentially from the starting end to the ending end. Curve segment a1 corresponds to curve segment b1, such that when the first push rod 84 is in the second driving position, the second push rod 85 is in the second driving range. Curve segment a2 corresponds to curve segment b2, such that when the first push rod 84 is in the second driving position, the second push rod 85 is in the second driving range. When moving between the first driving position and the first rest position, the second push rod 85 is located in the second rest position; curve segment a3 corresponds to curve segment b3, such that when the first push rod 84 is located in the first driving position, the second push rod 85 is located in the second rest position; curve segment a4 corresponds to curve segment b4, such that when the first push rod 84 moves between the first driving position and the first rest position, the second push rod 85 is located in the second rest position; curve segment a5 corresponds to curve segment b5, such that when the first push rod 84 is located in the first rest position, the second push rod 85 is located within the first driving range.

[0226] Thus, the first push rod 84 corresponds to both the first needle-starting triangle 12 (left needle-starting triangle) and the middle triangle 11, and the second push rod 85 corresponds to both the first density triangle 14 (left density triangle) and the pressure triangle 18. The first motor 81 can control the first needle-starting triangle 12, the middle triangle 11, the first density triangle 14 and the pressure triangle 18, reducing the number of drive components, lowering costs, saving installation space, making the triangle device lighter and faster.

[0227] As attached Figure 17As shown, the first curved groove 821 has a first alignment hole 822 at its starting end, and the second curved groove 831 has a second alignment hole 832 at its starting end. The line connecting the center of the first alignment hole 822 and the center of the first cam 82, and the line connecting the center of the second alignment hole 832 and the center of the second cam 83, are collinear, making the references of the first curved groove 821 and the second curved groove 831 the same. When the first motor 81 is in the initial state, the line connecting the center of the first alignment hole 822 and the center of the first cam 82 is adjacent to the center of the first cam 83. Figure 17 In the vertical position, the center line connecting the second alignment hole 832 and the center line of the second cam 83 is also attached. Figure 17 In the vertical state, the first protrusion is located at the end of curve segment a1, the first push rod 84 is located in the second drive position, the second protrusion is located at the intersection of curve segment b1 and curve segment b2, the distance between the end of curve segment b1 and the center B of the second cam 83 is Lb2, and the second push rod 85 is in the second rest position. At this time, the first starting triangle 12 moves inward to the inside of the triangle base plate 10 and is flush with the plane of the triangle base plate 10. It does not participate in the needle guide channel. The middle triangle 11 is in the full height position, protruding from the plane of the triangle base plate 10 and participating in the needle guide channel. The corresponding knitting method can be such as unidirectional knitting method or closing knitting method. At the same time, the first density triangle 14 is in the initial position, the presser triangle 18 does not work, and the triangle device is in a non-density adjustment mode. In summary, the triangle device is a unidirectional knitting mode without density adjustment.

[0228] When the first motor 81 is attached Figure 17 The initial position is rotated clockwise. The first protrusion 841 moves from the end of curve segment a1 to the beginning relative to the first cam 82, and the second protrusion 851 moves from the end of curve segment a2 to the beginning relative to the second cam 83. Curve segment a1 corresponds to curve segment b1, such that when the first push rod 84 is in the second driving position, the second push rod 85 is in the second driving range. The beginning end of curve segment a1 is the beginning end of the first curved groove 821, and the distance from the beginning end to the end of the first cam 82 to the center A of the first cam 82 is La1. When the first protrusion 841 is in curve segment a1, the first push rod 84 is in the second driving position. The beginning end of curve segment b1 is the beginning end of the second curved groove 831, and the distance from the beginning end to the end of the second cam 83 to the center B of the second cam 83 gradually increases, with a maximum distance of Lb1 and a minimum distance of Lb2. When the second protrusion 851 is in curve segment b1, the second push rod 85 is in the second driving range, as shown in the attached figure. Figure 19In the specific example shown, the second protrusion 851 is located at the beginning of the curve segment b1, and the second push rod 85 is at the highest point of the second drive range. At this time, the first starting triangle 12 moves inward toward the triangle base plate 10, becoming flush with the plane of the triangle base plate 10, and does not participate in the needle guide channel. The middle triangle 11 is at full height, protruding from the plane of the triangle base plate 10, and participates in the needle guide channel. The corresponding knitting method can be a unidirectional knitting method or a closed knitting method. At the same time, the first density triangle 14 moves along the through groove 101 on the triangle base plate 10 to adjust the knitting density of the second starting triangle 13. The presser triangle 18 is not working, and the triangle device is in density adjustment mode. In summary, the triangle device is a single-line knitting mode with density adjustment. The position of the second protrusion 851 in the curve segment b1 corresponds to the position of the second push rod 85 in the second drive range, and can be adjusted according to the required knitting density.

[0229] Curve segment a2 corresponds to curve segment b2, such that when the first push rod 84 moves between the second driving position and the first driving position, the second push rod 85 is located in the second rest position; specifically, see attached... Figure 14 As shown, curve segment a2 smoothly connects curve segments a1 and a3. From the connection end with curve segment a1 to the connection end with curve segment a3, the distance between curve segment a2 and the center A of the first cam 82 gradually decreases, with a maximum distance of La1 and a minimum distance of La2, as shown in the attached figure. Figure 16 As shown, curve segment b2 smoothly connects curve segments b1 and b3, and the distance between curve segment b2 and the center B of the second cam 83 is Lb2 from the connection end with curve segment b1 to the connection end with curve segment b3. The first motor 81 is attached... Figure 17 In the initial state, the first protrusion rotates counterclockwise relative to the first cam 82 from the connection end of curve segment a2 and curve segment a1 to the connection end of curve segment a2 and curve segment a3. The first push rod 84 moves from the second driving position to the first driving position until it reaches the position shown in the attached figure. Figure 20 As shown, the first protrusion reaches the connection end of curve segment a2 and curve segment a3, and the first push rod 84 is in the first driving position. During this process, the second protrusion moves relative to the second cam 83 from the connection end of curve segment b2 and curve segment b1 to the connection end of curve segment b2 and curve segment b3. The second push rod 85 is always in the second rest position. At this time, the middle triangle 11 moves to the inside of the triangle base plate 10 and is in the half-height position. The first starting triangle 12 is in the full-height position, protruding from the plane of the triangle base plate 10 and participating in the needle guide channel. The triangle device can perform hanging knitting, which is the hanging knitting mode. The left density triangle is in the initial position, the presser triangle 18 does not work, and the triangle device is in the non-density adjustment mode. In summary, the triangle device is the hanging knitting mode without density adjustment.

[0230] As attached Figure 20As shown, curve segment a3 corresponds to curve segment b3, such that when the first push rod 84 is in the first driving position, the second push rod 85 is in the second resting position; specifically, see attached... Figure 14 As shown, the distance from the starting end to the ending end of curve segment a3 to the center A of the first cam 82 is La2. Because curve segment a3 is relatively short, the first motor 8111 basically maintains its position relative to the center A of the first cam 82. Figure 20 In the current state, the first protrusion is located in curve segment a3, and the first push rod 843 is always in the first driving position. Meanwhile, as shown in the attached... Figure 16 As shown, the distance from the starting end to the end of curve segment b3 and the center B of the second cam 83 is Lb2. When the second protrusion 851 is located in curve segment b3, the second push rod 85 is always in the second rest position. At this time, the middle triangle 11 moves inward to the inside of the triangle base plate 10 and is in a half-height position. The first starting triangle 12 is in a full-height position, protruding from the plane of the triangle base plate 10 and participating in the needle guide channel. The triangle device can perform hanging knitting, which is a hanging knitting mode. The left density triangle is in the initial position, and the presser triangle 18 does not work. The triangle device is in a non-density adjustment mode. In summary, the triangle device is a hanging knitting mode without density adjustment. Curve segment a3 can keep the first push rod 84 in the first driving position, ensuring the stability of the hanging knitting mode and avoiding the situation where the first protrusion and the first cam 82 are not accurately matched, causing the first push rod 84 to fail to stay in the first driving position.

[0231] Curve segment a4 corresponds to curve segment b4, such that when the first push rod 84 moves between the first driving position and the first rest position, the second push rod 85 is located in the second rest position; specifically, see attached... Figure 14 As shown, curve segment a4 smoothly connects curve segments a3 and a5, and the distance between the curve segment a4 and the center A of the first cam 82 gradually decreases from the connection end with curve segment a3 to the connection end with curve segment a5, with a maximum distance of La2 and a minimum distance of La3; as shown in the attached figure. Figure 16 As shown, curve segment b4 smoothly connects curve segments b3 and b5, and the distance from the connection end with curve segment b3 to the connection end with curve segment b5 and the center B of the second cam 83 is Lb2. The first motor 81 is attached... Figure 20 The first protrusion rotates counterclockwise relative to the first cam 82 from the connection end of curve segment a4 and curve segment a3 to the connection end of curve segment a4 and curve segment a5. The first push rod 84 moves from the first driving position to the first rest position until it reaches the position shown in the attached figure. Figure 22 As shown, the first protrusion reaches the connection end of curve segment a4 and curve segment a5, and the first push rod 84 is in the first rest position. At the same time, the second protrusion moves relative to the second cam 83 from the connection end of curve segment b4 and curve segment b3 to the connection end of curve segment b4 and curve segment b5. The second push rod 85 is always in the second rest position. At this time, as shown in the attached figure...Figure 23 As shown, the first starting triangle 12 and the middle triangle 11 are in full height position, protruding from the plane of the triangle base plate 10, and participate in the needle guide channel, which is a full-mesh knitting mode. The left density triangle is in the initial position, the presser triangle 18 is not working, and the triangle device is in a non-density adjustment mode. In summary, the triangle device is a bidirectional full-mesh knitting mode without density adjustment.

[0232] As attached Figure 24 As shown, curve segment a5 corresponds to curve segment b5, such that when the first push rod 84 is in the first rest position, the second push rod 85 is in the first driving range. Specifically, the end of curve segment a5 is the end of the first curved groove 82113, and from the connection end with curve segment a4 to the end, the distance between curve segment a5 and the center A of the first cam 82 is La3. When the first protrusion 841 is in curve segment a5, the first push rod 84 is in the first rest position. The end of curve segment b5 is the end of the second curved groove 831, and due to the connection end with curve segment b4, the distance between curve segment b5 and the center B of the second cam 83 gradually increases, with a minimum distance of Lb2 and a maximum distance of Lb3. When the second protrusion 851 is in curve segment b5, the second push rod 85 is in the first driving range. The first motor 8111 is attached... Figure 22 The state continues to rotate counterclockwise. The first protrusion moves relative to the first cam 8212 from the connection end of curve segment a5 and curve segment a4 to the end. During this process, the first push rod 84 is in the first rest position. At the same time, the second protrusion moves relative to the second cam 83 from the connection end of curve segment b5 and curve segment b4 to the end. During this process, the second push rod 85 is in the first driving range. At this time, the first starting triangle 12 and the middle triangle 11 are in the full height position, protruding from the plane of the triangle base plate 10, and participate in the needle guide channel, which is a full-mesh knitting mode. The first density triangle 14 moves along the density adjustment groove on the triangle base plate 10, and the pressure triangle 18 descends to the required height to participate in the work. The triangle device is a pressure adjustment mode with adjustable pressure needle height. In summary, the triangle device is a full-mesh knitting mode with adjustable pressure needle height. If the triangle device in this embodiment is a bidirectional knitting triangle device, its full-mesh knitting mode is a bidirectional knitting mode. The position of the second protrusion 851 in curve segment b5 corresponds to the position of the second push rod 85 in the first driving range, and can be adjusted according to the required pressure needle height.

[0233] It should be noted that the distance between the curved segment b5 and the center B of the second cam 83 is relatively large, requiring a large motor torque. Therefore, the curved segment b5 needs to be set to be relatively smooth. Specifically, the central angle corresponding to the curved segment b5 is 125°-145°, preferably 135°, so that the second protrusion can move normally in the longer curved segment b5 under the action of the second motor 91, avoiding the second protrusion from being unable to move relative to the second cam 83 due to insufficient torque of the second motor 91.

[0234] As attached Figure 25 and attached Figure 26 As shown, the second drive assembly 90 includes a second motor 91, a third push rod 93 and a third cam 92. The second motor 91 drives the third cam 92 to rotate, so that the third push rod 93 has a third rest position and at least one working position. When the third push rod 93 is in the working position, it can drive the second density push foot 71 of the third control assembly 70.

[0235] As attached Figure 26 As shown, the working positions of the third push rod 93 include a first working range, a first working position, and a second working position. When the third push rod 93 is in the third rest position, it contacts the second density push foot 71 and puts the second density push foot 71 in its initial position. The second density triangle 15 is in its original position, and the elastic band triangle 16 is in a flush position. When the third push rod 93 is in the first working range, it pushes the second density push foot 71, causing the second density push foot 71 to move along the through inclined groove 101. The second density triangle 15 moves within the density adjustment range, and the elastic band triangle 16 is in a flush position. When the third push rod 93 is in the first working position, it pushes the second density push foot 71. The second density push foot 71 moves along the through groove 101, causing the second density triangle 15 to exceed the density adjustment range, and the elastic band triangle 16 to be in a half-height position. When the third push rod 93 is in the second working position, the elastic band triangle 16 is in a half-height position. The second density triangle 15 and the elastic band triangle 16 form an elastic band guide needle channel that limits the height of the elastic band. As can be seen from the above, the distance between the first guide block 151 of the second density triangle 15 and the elastic band triangle 16 can limit the height of the knitting needle 40 corresponding to the elastic band, so that the elastic band can accurately match the insertion port of the sinker, reducing the probability of elastic band breakage or skipped stitches.

[0236] Specifically, the third cam 92 is provided with a third curved groove 921 that allows the third push rod 93 to be guided to the third rest position, the first working range, the first working position, and the second working position. The third push rod 93 is provided with a third inclined groove 932 and a third protrusion 931. The central axis of the third cam 92 passes through the third inclined groove 932 and the third protrusion 931 is placed in the third curved groove 921. The rotation of the second motor 91 causes the third protrusion 931 to move along the third curved groove 921 to change the relative position of the third protrusion 931 and the central axis of the third cam 92, thereby driving the third push rod 93 to move between the third rest position, the first working range, the first working position, and the second working position.

[0237] As attached Figure 25As shown, the third curved groove 921 includes curved segments c1, c2, and c3. The starting end of curved segment c1 is the starting end of the third curved groove 921. The distance from the starting end to the end of curved segment c1 and the center C of the third cam 92 is Lc1, which corresponds to the third rest position of the third push rod 93. At this time, the second density triangle 15 is in the initial position, which is the lowest end of the through inclined groove 101, and the elastic band triangle 16 is in the flush position. The triangle device cannot perform elastic band weaving.

[0238] Curved segment c2 smoothly connects curved segment c1 and curved segment c3. From the connection end of curved segment c2 with curved segment c1 to the connection end with curved segment c3, the distance between curved segment c2 and the center C of the third cam 92 gradually increases. The distance between the connection end of curved segment c2 and curved segment c1 and the center C of the third cam 92 is Lc1, and the distance between the connection end of curved segment c2 and curved segment c3 and the center C of the third cam 92 is Lc2. When the third protrusion moves relative to the third cam 92 in curved segment c2 but does not reach the connection end of curved segment c2 and curved segment c3, the third push rod 93 is in the first working range, pushing the second density push foot 71 so that the second density push foot 71 moves along the through inclined groove 101. The second density triangle 15 moves within the density adjustment range, which can adjust the density of the first needle-starting triangle 12. The elastic band triangle 16 is in the flush position.

[0239] When the third protrusion moves relative to the third cam 92 to the connection end of the curve segment c2 and the curve segment c3, the third push rod 93 is in the first working position, the second density triangle 15 is out of the density adjustment range, and the elastic band triangle 16 is in the half-height position.

[0240] The end of curve segment c3 is the end of the third curved groove 921. From the connection end with curve segment c2 to the end, the distance between curve segment c3 and the center C of the third cam 92 gradually increases. The distance between the end of curve segment c3 and the center C of the third cam 92 is Lc3, where Lc3 > Lc2 > Lc1. When the third protrusion moves towards the end of curve segment c3 relative to the third cam 92, the third push rod 93 moves from the first working position to the second working position. The distance between the first guide block 151 on the second density triangle 15 and the elastic triangle 16 gradually increases until the third protrusion moves to the end of curve segment c3 relative to the third cam 92, and the third push rod 93 reaches the second working position. The height of the second density triangle 15 within the through groove 101 allows the first guide block 151 to limit the height of the knitting needle 40 corresponding to the elastic, enabling the elastic to precisely match the insertion port of the sinker.

[0241] Since the third push rod 93 is controlled by the second drive mechanism and is independent of the first drive mechanism, it can cooperate with the first push rod 84 and the second push rod 85, and the triangular device can realize the various weaving patterns mentioned above.

[0242] Compared to the two push rods in the prior art, the triangular control drive mechanism in the glove machine of this embodiment, through the first push rod 84, the second push rod 85 and the third push rod 93, has multiple different positions under the control of the first drive mechanism and the second drive mechanism respectively. It can cooperate with the triangular device to realize multiple different weaving patterns and has the advantages of simple structure and multiple combination methods.

[0243] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
