Description

Technical Field

[0001] The present invention relates to the technical field of fabric knitting equipment, and in particular to a flat knitting machine and a knitting method. Background Art

[0002] CN201921376257.1 discloses a head drive device for a knitting glove machine, which represents the basic operating principle of all knitting glove machines currently on the market: when knitting the cylindrical portion of the glove, the needle guide head moves from left to right. The needle raising cam on the base plate of the needle guide cam in the rear needle guide head (front and back are defined as the front view of the machine facing the user) pushes up the knitting needles on the rear needle bed and feeds the yarn in a yarn feeder (shuttle) to complete one knitting motion. Conversely, when the needle guide head moves from right to left, the needle raising cam on the base plate of the needle guide cam in the front needle guide head pushes up the knitting needles on the front needle bed and feeds the yarn in the same yarn feeder to complete another knitting motion. Thus, the needle guide head completing a reciprocating motion from left to right and back to the left is called completing one course of stitches (of course, some machines also call starting from the right and returning to the right a round trip and count it as one course of stitches). This cycle continues, and the yarn is woven in a spiral pattern.

[0003] When knitting the fingertips of the seam part of the glove, the front and rear needle guide heads push up the knitting needles on their respective front and rear needle beds at the same time. The front and rear needles are staggered to eat the same yarn. This knitting action is called seaming in the industry, that is, the knitted structure knitted by the front and rear needle beds at this time is sewn together.

[0004] The only way to increase production for all glove knitting machines currently on the market is to increase the speed of the needle guide head, thereby achieving high output. However, this results in accelerated machine wear and increased failure rates, and even more fatally, it does not significantly increase glove knitting machine production capacity.

The front second pushing assembly 81 is driven by an external force to enable the front middle triangle 75 to switch from a full-height position to a half-height position, and then switch from a half-height position to a full-height position. The front second pushing assembly 81 is installed on the back of the front bottom plate body; wherein, the front second pushing assembly 81 includes a second rotating member 811 and a second driving rod 812, the second driving rod 812 is rotatably provided on the front triangle bottom plate 71, one end of the second driving rod 812 is rotatably connected to the second rotating member 811, and a second movable rod 813 that passes through the front triangle bottom plate 71 is provided on the back of the front middle triangle 75, and the second movable rod 813 is located at the end portion on the outer side of the back of the front triangle bottom plate 71 A second protrusion 814 is provided; the second driving rod 812 is provided with a first inclined surface 815 and a first high surface 817 in sequence at one end close to the second protrusion 814, wherein the second driving rod 812 rotates, and the second protrusion 814 rotates relatively to the lowest point of the first inclined surface 815. At this time, the front middle triangle 75 is in the full height position, and then continues to rotate, and the second protrusion 814 rotates relatively to the first high surface 817, and the front middle triangle 75 is in the half height position. At this time, if the other triangles are in the full height position, that is, the front left density triangle 72, the front left needle raising triangle 73, the front middle triangle 75, the front knitting needle triangle 74, the front right needle raising triangle 76 and the front right density triangle 77 form a half needle path, that is, this path is the tuck knitting path.

[0152] Further, such as Figure 8As shown, in order to optimize the driving mechanism, the front middle triangle 75 and the front left needle triangle 73 are linked, and a second inclined surface 816 and a first concave surface 818 are further provided at one end of the second driving rod 812 close to the second protruding rod 814. The first inclined surface 815 and the second inclined surface 816 are arranged opposite to each other, and the first high surface 817 is connected to the highest point of the first inclined surface 815 and the highest point of the second inclined surface 816 to form a first boss 819.

When the third rotating member 823 is subjected to external force, the third rotating member 823 is lifted up and moves upward, and then drives the first rod 821 and the second rod 822. The second rod 822 drives the front right sliding seat 85 to slide in the front right adjustment groove, so that the front right sliding seat 85 is away from the second mounting plate 84, and the second lifting surface 826 is away from the third protruding rod 825 and passes through the sixth reset spring. The positioning spring causes the front elastic triangle 78 to move from the flush position to the semi-high position, forming an elastic guide needle channel; in this embodiment, the knitting needle moves to the left relative to the front guide needle head 4, and the head weaves to the right, the front elastic triangle 78 is to the semi-high position, and the knitting needle enters the elastic guide needle channel, and the high-position knitting needle first hooks the elastic thread, and then during normal full-mesh knitting, the pre-hooked elastic is first forked by the sinker and is not knitted, and is wrapped by the yarn of normal full-mesh knitting to form a cuff structure, and then the knitting needle is in the return stroke, that is, when it moves to the right relative to the front head, the front elastic triangle 78 is to the flush position, and the elastic does not participate in knitting.

[0156] The front guide needle head 4 also includes a front fourth pushing assembly 86 for adjusting the front left density cam 72, the front fourth pushing assembly 86 is arranged on the front triangular bottom plate 71, the front fourth pushing assembly 86 includes a fourth driving rod 862 and a fourth rotating member 861, the fourth rotating member 861 is rotatably arranged on the fourth driving rod 862; the front triangular bottom plate 71 is provided with a front left sliding seat 865, the front left sliding seat 865 is slidably arranged in the front left sliding through groove opened on the front triangular bottom plate 71, the front left sliding seat 865 is connected to the front left density cam 72, one end of the fourth driving rod 862 is rotatably arranged on the front triangular bottom plate 71, and the other end is rotatably connected to the front left sliding seat 865; and the front triangular bottom plate 71 is also provided with a front pressing needle cam 98, the front pressing needle cam 98 is arranged on the front left density cam 7 On the left side, the front pressing cam 98 slides vertically in the front vertical through slot provided on the front triangle bottom plate 71; the front fourth pushing assembly 86 also includes a second connecting rod assembly, which includes a third rod 863 and a fourth rod 864. One end of the third rod 863 is rotatably connected to the fourth driving rod 862, and the other end of the third rod 863 is connected to one end of the fourth rod 864. The other end of the fourth rod 864 is connected to the back of the front pressing cam 98. When the fourth rotating member 861 is subjected to an external force, the fourth rotating member 861 is lifted up and then drives the fourth driving rod 862. The fourth driving rod 862 causes the front left sliding seat 865 to slide upward, thereby sliding the front right density cam 77 upward, and the front pressing cam 98 also slides in the front vertical through slot to achieve linkage. Specifically, a thirteenth return spring 90 is provided between the back of the front pressure needle triangle 98 and the back of the front bottom plate body, and a fourteenth return spring 91 is provided between the front left density triangle 72 and the back of the front bottom plate body. After the external force cancels the lifting force on the fourth rotating part 861, the thirteenth return spring 90 is used to reset the front pressure needle triangle 98, and the fourteenth return spring 91 is used to reset the front left density triangle 72.

[0157] Specifically, such as Figure 13-15 As shown, the front triangle bottom plate 71 also includes a front left return needle assembly, and the front left return needle assembly includes a front left return needle cam 93 and a front left blocking cam 92. The front left blocking cam 92 is located above the front left return needle cam 93, and a front left return needle path is formed between the two. The front left return needle cam 93 is installed between the front pressure needle cam 98 and the front left density cam 72. The upper end surface of the front elastic guide cam 79 is provided with a front right return needle surface 94. The front left return needle path and the front right return needle surface 94 are located above the front knitting needle cam 74, and the knitting needle butts are returned to the same height, so that the needle butts of bidirectional knitting can all be returned to the same height to ensure the consistency of coil knitting; the return needle path is as shown in FIG. Figure 15 shown.

[0158] Specifically, the front left return needle triangle 93 includes a front left return needle surface 932, and the front left return needle surface 932 is at the same height as the front right return needle surface 94. The first guide surface 931 and the second guide surface 933 are connected on both sides of the front left return needle surface 932. The first guide surface 931 is tilted upward, and the second guide surface 933 is tilted downward. The front left needle blocking triangle 92 includes a front left needle blocking surface 922, and the first guide surface 921 and the second guide surface 923 are connected on both sides of the front left needle blocking surface 922. The first guide surface 921 is tilted downward, and the second guide surface 923 is tilted upward; thereby, some knitting needles may be Inertia, the tightness of the needle groove, and the strength of the yarn tension will cause the needle to be strung up and down, so that the height of the needle butt will be lower than or higher than the front left return needle surface 932, so that the needle butt will move to the front left return needle surface 932 under the guidance of the first guide surface 921 or the first guide surface 931; when the needle butt moves from right to left relative to the front triangle bottom plate 71, due to the adjustment of the front left density triangle 72, the height of the needle butt will be lower than or higher than the front left return needle surface 932, and the needle butt will move to the front left return needle surface 932 under the guidance of the second guide surface 923 or the second guide surface 933. Preferably, the inclination angle of the first guide surface 921 is set to 30-60°, and the inclination angle of the second guide surface 923 is set to 30-60°. Figure 13 As shown, the inclination angle of the first guide surface 921 is shown as A, and the inclination angle of the second guide surface 923 is shown as B. Because the angle is too small, the butt of the knitting needle is better protected, but the knitting stroke is too long. When the angle is too large, the knitting stroke is short, but when the cam device moves horizontally quickly, the downward pressure on the butt of the knitting needle is small, and the lateral force is large, which will cause needle punching and serious wear problems. Therefore, the above scheme can effectively protect the butt of the knitting needle, extend its service life and shorten the knitting stroke to a certain extent. In this embodiment, the inclination angle of the first guide surface 921 and the second guide surface 923 is set to 45°.

[0159] Specifically, a first needle lifting surface 95 and a second needle lifting surface 96 are provided on both sides of the front right return needle surface 94, so that when the needle butt of the knitting needle moves from right to left relative to the front triangle bottom plate 71, some needles will cause the needles to be strung up and down due to inertia, the tightness of the needle groove, and the tension of the yarn, so that the height of the needle butt will be lower than the front left return needle surface 932, so that the needle butt of the knitting needle will move to the front right return needle surface 94 under the guidance of the second needle lifting surface 96; when the needle butt of the knitting needle moves from left to right relative to the front triangle bottom plate 71, due to the adjustment of the front right density triangle 77, the height of the needle butt will be lower than the front right return needle surface 94, and the needle butt of the knitting needle will move to the front right return needle surface 94 under the guidance of the first needle lifting surface 95.

[0160] Preferably, the angle between the line between the high end and the low end of the first needle lifting surface 95 and the front right return needle surface 94 is E, and the value range is 15-40 degrees. The angle between the line between the high end and the low end of the second needle lifting surface 96 and the front right return needle surface 94 is F, and the value range is 15-40 degrees. Within this angle range, the slopes of the first needle lifting surface 95 and the second needle lifting surface 96 will be relatively gentle, so as to avoid the needle butt of the knitting needle from being inertial after the first needle lifting surface 95 or the second needle lifting surface 96 has finished moving. The first needle lifting surface 95 can be a bevel or an arc surface. In this embodiment, the angle between the line between the high end and the low end of the first needle lifting surface 95 and the front right return needle surface 94 is 20 degrees, and the angle between the line between the high end and the low end of the second needle lifting surface 96 and the front right return needle surface 94 is 20 degrees. The first needle lifting surface 95 is an arc surface, and the center angle range of the first needle lifting surface 95 and the front right needle lifting surface is 20-30 degrees. Figure 14 In the figure, the central angle of the first needle lifting surface 95 is shown as C, and the central angle of the second needle lifting surface 96 is shown as D. The radius setting range is 25-30 mm. Within this range, the first needle lifting surface 95 and the second needle lifting surface 96 are more stable.

[0161] The lower end of the second guide surface 933 is also provided with a first guide surface 934 that cooperates with the guide surface of the lower part of the front left density triangle 72. When the front left density triangle 72 drops to the extreme position, the butt of the knitting needle will move to the first guide surface 934, and then cooperate with the guide surface of the lower part of the front left density triangle 72, so that there is a sufficiently long guide path for the coil to be formed into a loop, and then it is directly lifted through the second guide surface 933, moved to the front left return needle surface 932, and returned to a certain height. Furthermore, the first guide surface 934 is set on the front left return needle triangle 93, which can further reduce the volume of the front left density triangle 72, and can further reduce the space occupied by the sliding of the front left density triangle 72. Preferably, the lower end of the first needle lifting surface 95 is provided with a second guide needle surface 97 for use with the guide needle surface at the bottom of the density triangle. When the density triangle drops to the extreme position, the butt of the knitting needle will move to the second guide needle surface 97 and then cooperate with the guide needle surface at the bottom of the density triangle, so that there is a sufficiently long guide needle path to enable the coil to form a loop, and then it is directly lifted through the first needle lifting surface 95 or the second needle lifting surface 96, moved to the front right return needle surface 94, and returned to a certain height. Furthermore, the second guide needle surface 97 is set on the front right return needle triangle, which can further reduce the volume of the front right density triangle 77 and further reduce the space occupied by the sliding of the front right density triangle 77. Moreover, the lower end of the first needle lifting surface 95 or the second needle lifting surface 96 is provided with a convex portion, and the second guide needle surface 97 is the upper end surface of the convex portion.

The first push rod 103 is in contact with the first rotating member 801 and the second rotating member 811 at the same time under the action of the first driving mechanism, and is used to control the working positions of the front middle cam 75 and the front left needle raising cam 73. When the first push rod 103 is in the first rest position, the front left needle raising cam 73 and the front middle cam 75 are in full height, protruding from the plane of the front cam bottom plate 71, and a bidirectional The needle guide path is a bidirectional full-mesh knitting mode.

The front middle triangle 75 is in a full-high position and participates in the needle path. A unidirectional needle guide path is formed in the front guide needle head 4, which is a unidirectional knitting mode.

[0164] 8 and the front pressing cam 98 are in the non-density adjustment mode.

[0165] Specifically, the first push rod 103 and the second push rod 106 are both controlled by the first driving mechanism. Specifically, the first driving mechanism includes a first motor 101, a first cam 102 corresponding to the first push rod 103 and a second cam 105 corresponding to the second push rod 106. The first cam 102 and the second cam 105 are both transmission-connected to the first output shaft of the first motor 101. The first cam 102 is provided with a first curved groove capable of enabling the first push rod 103 to reach the first rest position, the first driving position and the second driving position; the second cam 105 is provided with a second curved groove capable of enabling the second push rod 106 to reach the second rest position, the first driving range and the second driving range; in order to achieve the relative movement of the first cam 102 and the first push rod 103, the first push rod 103 is provided with a first inclined groove 1031 and a first protrusion 1032, and the first output shaft passes through the first output shaft 101. A bevel groove 1031 and a first protrusion 1032 are placed in the first curved groove, and the first motor 101 rotates to make the first protrusion 1032 move along the first curved groove to change the relative position of the first protrusion 1032 and the first output shaft, and drive the first push rod 103 to move between the first rest position, the first driving position and the second driving position; in order to realize the relative movement of the second cam 105 and the second push rod 106, the second push rod 106 is provided with a second bevel groove 1061 and a second protrusion 1062, the first output shaft passes through the second bevel groove 1061 and the second protrusion 1062 is placed in the second curved groove, and the first motor 101 rotates to make the second protrusion 1062 move along the second curved groove to change the relative position of the second protrusion 1062 and the first output shaft, and drive the second push rod 106 to move between the second rest position, the first driving range and the second driving range.

[0166] Specifically, such as Figure 18As shown, the first curved groove includes a curved segment a1 1022, a curved segment a2 1023, a curved segment a3 1024, a curved segment a4 1025, and a curved segment a5 1026, which are sequentially connected from the starting end to the end. The starting end of the curved segment a1 1022 is the starting end of the first curved groove, and the distance from the starting end to the end to the center A of the first cam 102 is La1. The curved segment a2 1023 is smoothly connected between the curved segment a1 1022 and the curved segment a3 1024. From the connection end with the curved segment a1 1022 to the connection end with the curved segment a3 1024, the distance between the curved segment a2 1023 and the center A of the first cam 102 gradually decreases, with the maximum distance being La1 and the minimum distance being La2. The distance from the curved segment a3 1024 to the center A of the first cam 102 is La2 from the starting end to the end. The curved segment a4 1025 is smoothly connected to the curved segment a3 1024. 1024 and the curved segment a5 1026, and from the connection end with the curved segment a3 1024 to the connection end with the curved segment a5 1026, the distance from the center A of the first cam 102 gradually decreases, the maximum distance is La2, and the minimum distance is La3.

Therefore, the height of the first driving position is lower than the height of the second driving position.

[0167] More preferably, the curve segment a2 1023 includes a first buffer arc segment 10231, a first lifting arc segment 10232 and a second buffer arc segment 10233 connected in sequence, the center of the first buffer arc segment 10231 is located on the side close to the center A of the first cam 102, and the corresponding radius is Ra1, the center of the first lifting arc segment 10232 is located on the side close to the center A of the first cam 102, and the corresponding radius is Ra2, and the center of the second buffer arc segment 10233 is located on the side away from the center A of the first cam 102, and the corresponding radius is Ra3, satisfying the following relationship: Ra2>Ra1>Ra3, so that the transition between the curve segment a1 1022 and the curve segment a2 1023, and the transition between the curve segment a2 1023 and the curve segment a3 1024 are smoother, and the first push rod 103 can be smoothly and steadily lifted or lowered, and move between the first limit position and the second limit position; the curve segment a4 1025 includes a third buffer arc segment 10251, a second lifting arc segment 10252 and a fourth buffer arc segment 10253 connected in sequence. The center of the third buffer arc segment 10251 is located on the side close to the center A of the first cam 102, and the corresponding radius is Rb1. The center of the second lifting arc segment 10252 is located on the side close to the center A of the first cam 102, and the corresponding radius is Rb2. The center of the fourth buffer arc segment 10253 is located on the side away from the center A of the first cam 102, and the corresponding radius is Rb3, satisfying the following relationship: Rb2>Rb1>Rb3, so that the transition between the curve segment a3 1024 and the curve segment a4 1025, and the transition between the curve segment a4 1025 and the curve segment a5 1026 are smoother, and the first push rod 103 can be lifted or lowered smoothly and steadily, and move between the first limit position and the first rest position.

[0168] like Figure 19As shown, the second curved groove includes a curved segment b1 1052, a curved segment b2 1053, a curved segment b3 1054, a curved segment b4 1055, and a curved segment b5 1056, which are sequentially connected from the starting end to the end. The starting end of the curved segment b1 1052 is the starting end of the second curved groove, and the distance from the center B of the second cam 105 to the end gradually increases, with a maximum distance of Lb1 and a minimum distance of Lb2. The curved segment b2 1053 is smoothly connected between the curved segment b1 1052 and the curved segment b3 1054, and the distance from the curved segment b2 1053 to the center B of the second cam 105 from the connection end with the curved segment b1 1052 to the connection end with the curved segment b3 1054 is Lb2. The distance from the curved segment b3 1054 to the center B of the second cam 105 from the starting end to the end is Lb2. The curved segment b4 1053 is Lb2. 1055 smoothly connects between curved segment b3 1054 and curved segment b5 1056. From its connection with curved segment a3 1024 to its connection with curved segment a5 1026, the distance from the center B of the second cam 105 is Lb2. The end of curved segment b5 1056 is aligned with the end of the second curved groove. Due to the increasing distance from the connection end to the end of curved segment b4 1055, the distance from the center B of the second cam 1055 gradually increases, reaching a minimum distance of Lb2 and a maximum distance of Lb3, satisfying the following relationship: Lb2 < Lb1 < Lb3. As a result, the maximum height of the first drive range is higher than that of the second drive range. This arrangement is based on the structure of the corresponding triangular push assembly.

[0169] As attached Figure 21 As shown, the starting end of the first curved groove is provided with a first alignment hole 1021, and the starting end of the second curved groove is provided with a second alignment hole 1051. The center line connecting the first alignment hole 1021 and the first cam 102 and the center line connecting the second alignment hole 1051 and the second cam 105 are collinear, so that the reference of the first curved groove and the second curved groove are the same. When the first motor 101 is in the initial state, the center line connecting the first alignment hole 1021 and the first cam 102 is the same. Figure 21 In the vertical state, the center line between the second alignment hole 1051 and the second cam 105 is also attached. Figure 21In the vertical state, the first protrusion is located at the end of the curve segment a1 1022, the first push rod 103 is located at the second driving position, the second protrusion is located at the intersection of the curve segment b1 1052 and the curve segment b2 1053, and the curve segment b1 The distance between the end of 1052 and the center B of the second cam 105 is Lb2, and the second push rod 106 is in the second rest position. At this time, the front left needle-raising triangle 73 moves toward the inside of the triangle base plate and is flush with the plane of the triangle base plate, and does not participate in the needle path. The front middle triangle 75 is in the full height position, protruding from the plane of the front triangle base plate 71, and participates in the needle path. The leading needle head 4 can perform one-way weaving. When the front right needle-raising triangle 76 is in the full height position and serves as a seam triangle, the leading needle head 4 is in the sealing weaving mode. At the same time, the front left density triangle 72 is in the initial position, the front pressure triangle 98 does not work, and the leading needle head 4 is in the non-density adjustment mode. In summary, the leading needle head 4 is in the sealing weaving mode without density adjustment.

[0170] When the first motor 101 is Figure 21 The first protrusion 1032 moves from the end of the curve segment a1 1022 to the starting end relative to the first cam 102, and the second protrusion 1062 moves from the end of the curve segment a2 1023 to the starting end relative to the second cam 105. The curve segment a1 1022 corresponds to the curve segment b1 1052, so that when the first push rod 103 is in the second driving position, the second push rod 106 is in the second driving range. The starting end of the curve segment a1 1022 is the starting end of the first curved groove, and the distance from the starting end to the end to the center A of the first cam 102 is La1. When the first protrusion 1032 is in the curve segment a1 1022, the first push rod 103 is in the second driving position; the curve segment b1 The starting end of 1052 is the starting end of the second curved groove, and the distance from the starting end to the end to the center B of the second cam 105 gradually increases, with the maximum distance being Lb1 and the minimum distance being Lb2. When the second protrusion 1062 is located in the curved segment b1 1052, the second push rod 106 is located in the second driving range, as shown in the attached figure. Figure 22In the specific example shown, the second protrusion 1062 is at the starting end of the curved segment b1 1052, and the second push rod 106 is at the highest height in the second drive range. At this time, the front left cast-on cam 73 moves toward the inside of the cam base plate, flush with the plane of the cam base plate, and does not participate in the needle path. The front middle cam 75 is at its full height, protruding above the plane of the cam base plate and participating in the needle path. The front guide needle head 4 is capable of unidirectional knitting. When the front right cast-on cam 76 is at its full height and functions as a seam cam, the front guide needle head 4 is in a closed knitting mode. Simultaneously, the front left density cam 72 moves along the density adjustment slot on the cam base plate to adjust the knitting density of the front right cast-on cam 76. The front presser cam 98 is inactive, and the front guide needle head 4 is in a density adjustment mode. In summary, the front guide needle head 4 is in a closed knitting mode with density adjustment. The position of the second protrusion 1062 in the curved segment b1 1052 corresponds to the position of the second push rod 106 in the second drive range and can be adjusted according to the desired knitting density.

[0171] The curve segment a2 1023 corresponds to the curve segment b2 1053, so that when the first push rod 103 moves between the second driving position and the first driving position, the second push rod 106 is located in the second rest position. Specifically, the curve segment a2 1023 is smoothly connected between the curve segment a1 1022 and the curve segment a3 1024, and the distance between the curve segment a2 1023 and the center A of the first cam 102 gradually decreases from the connection end with the curve segment a1 1022 to the connection end with the curve segment a3 1024, with the maximum distance being La1 and the minimum distance being La2. The curve segment b2 1053 is smoothly connected between the curve segment b1 1052 and the curve segment b3 1054, and the distance between the curve segment b2 1053 and the center B of the second cam 105 is Lb2 from the connection end with the curve segment b1 1052 to the connection end with the curve segment b3 1054. The first motor 101 is provided by the attached Figure 21 The first projection moves relative to the first cam 102 from the connection end of the curve segment a2 1023 and the curve segment a1 1022 to the connection end of the curve segment a2 1023 and the curve segment a3 1024, and the first push rod 103 moves from the second driving position to the first driving position until the first push rod 103 is in the state shown in the figure. Figure 23As shown, the first protrusion reaches the connection end of the curved segment a2 1023 and the curved segment a3 1024, and the first push rod 103 is in the first driving position. During this process, the second protrusion moves relative to the second cam 105 from the connection end of the curved segment b2 1053 and the curved segment b1 1052 to the connection end of the curved segment b2 1053 and the curved segment b3 1054, and the second push rod 106 is always in the second rest position. At this time, the front middle cam 75 moves toward the inside of the cam base plate and is in a half-height position. The front left needle raising cam 73 is in a full-height position, protruding from the plane of the cam base plate and participating in the needle path. The leading needle head 4 can perform tuck knitting in the tuck knitting mode. The front left density cam 72 is in the initial position, the front press cam 98 is not working, and the leading needle head 4 is in the non-density adjustment mode. In summary, the leading needle head 4 is in the tuck knitting mode without density adjustment.

[0172] As attached Figure 22 As shown, the curve segment a3 1024 corresponds to the curve segment b3 1054, so that when the first push rod 103 is in the first driving position, the second push rod 106 is in the second resting position; specifically, the distance between the starting end and the end of the curve segment a3 1024 and the center A of the first cam 102 is La2. Since the length of the curve segment a3 1024 is short, the first motor 101 is kept in the vicinity. Figure 23 In the state of or slightly rotated counterclockwise by a corresponding angle, the first protrusion is in the curved segment a3 1024, and the first push rod 103 is always in the first driving position. At the same time, the distance between the curved segment b3 1054 from the starting end to the end and the center B of the second cam 105 is Lb2. When the second protrusion 1062 is in the curved segment b3 1054, the second push rod 106 is always in the second rest position. At this time, the front middle cam 75 moves toward the inside of the cam base plate and is in a half-height position. The front left needle raising cam 73 is in a full-height position, protruding from the plane of the cam base plate and participating in the needle path. The leading needle head 4 can perform tuck knitting in the tuck knitting mode. The front left density cam 72 is in the initial position, the front press cam 98 is not working, and the leading needle head 4 is in the non-density adjustment mode. In summary, the leading needle head 4 is in the tuck knitting mode without density adjustment. The curved segment a3 1024 can keep the first push rod 103 in the first driving position, ensuring the stability of the tuck knitting pattern and avoiding the situation where the first push rod 103 cannot be kept in the first driving position due to inaccurate cooperation between the first protrusion and the first cam 102.

[0173] Curve segment a4 1025 corresponds to curve segment b4 1055, so that when the first push rod 103 moves between the first driving position and the first rest position, the second push rod 106 is located at the second rest position. Specifically, curve segment a4 1025 is smoothly connected between curve segment a3 1024 and curve segment a5 1026, and the distance from the center A of the first cam 102 gradually decreases from the connection end with curve segment a3 1024 to the connection end with curve segment a5 1026, with the maximum distance being La2 and the minimum distance being La3.

Figure 24 As shown, the first projection reaches the connecting end of the curved segment a4 1025 and the curved segment a5 1026, and the first push rod 103 is in the first rest position. At the same time, the second projection moves relative to the second cam 105 from the connecting end of the curved segment b4 1055 and the curved segment b3 1054 to the connecting end of the curved segment b4 1055 and the curved segment b5 1056, and the second push rod 106 is always in the second rest position. At this time, the front left needle raising cam 73 and the front middle cam 75 are in full height positions, protruding from the plane of the cam bottom plate, participating in the needle path, and are in full mesh knitting mode. The front left density cam 72 is in the initial position, the front pressure cam 98 does not work, and the leading needle head 4 is in the non-density adjustment mode. In summary, the leading needle head 4 is a full mesh knitting mode without density adjustment.

[0174] Curve segment a5 1026 corresponds to curve segment b5 1056, so that when the first push rod 103 is in the first rest position, the second push rod 106 is in the first driving range. Specifically, the end of curve segment a5 1026 is the end of the first curved groove 13, and from the connection end with curve segment a4 1025 to the end, the distance between curve segment a5 1026 and the center A of the first cam 102 is La3. When the first protrusion 1032 is in curve segment a5 1026, the first push rod 103 is in the first rest position; the end of curve segment b5 1056 is at the end of the second curved groove, and due to the connection end to the end of curve segment b4 1055, the distance between curve segment b5 1056 and the center B of the second cam 105 gradually increases, with a minimum distance of Lb2 and a maximum distance of Lb3. When the second protrusion 1062 is in curve segment b5 1056, the second push rod 106 is in the first driving range. The first motor 101 is provided by Figure 24 Continuing to rotate counterclockwise in the state in which the first projection moves relative to the first cam 102 from the connection end of the curved segment a5 1026 and the curved segment a4 1025 to the end, during which the first push rod 103 is located in the first rest position. Simultaneously, the second projection moves relative to the second cam 105 from the connection end of the curved segment b5 1056 and the curved segment b4 1055 to the end, during which the second push rod 106 is located in the first driving range, as shown in the attached figure. Figure 25 As shown, at this time, the front left needle cam 73 and the front middle cam 75 are at full height, participating in the needle path, in the full mesh knitting mode, the front left density cam 72 moves along the density adjustment groove on the cam base, and the front presser cam 98 drops to the required height and participates in the work. The front guide needle head 4 is in the presser adjustment mode with adjustable presser height. In summary, the front guide needle head 4 is in the full mesh knitting mode with adjustable presser height. If the front guide needle head 4 of this embodiment is a front guide needle head 4 that can knit bidirectionally, its full mesh knitting mode is a bidirectional knitting mode. The position of the second protrusion 1062 in the curve segment b5 1056 corresponds to the position of the second push rod 106 in the first driving range, and can be adjusted according to the required presser height.

[0175] like Figure 20 、 26 As shown in Figure 27, the third push rod 109 has a third rest position, a first working range, a first working position and a second working position under the action of the second driving mechanism.

[0176] The third curved groove includes curved segment c1 1081, curved segment c2 1082 and curved segment c3 1083. The starting end of curved segment c1 1081 is the starting end of the third curved groove. The distance from the starting end to the end of curved segment c1 1081 and the center C of the third cam 108 is Lc1, corresponding to the third rest position of the third push rod 109. At this time, the front right density triangle 77 is in the initial position, that is, the lowest end of the front right sliding groove, the front elastic triangle 78 is in the flush position, and the four front guide needle heads cannot weave elastic.

[0177] The curve segment c2 1082 smoothly connects the curve segment c1 1081 and the curve segment c3 1083. The distance between the curve segment c2 1082 and the center C of the third cam 108 gradually increases from the connection end with the curve segment c1 1081 to the connection end with the curve segment c3 1083. The distance between the connection end of the curve segment c2 1082 and the curve segment c1 1081 and the center C of the third cam 108 is Lc1, and the distance between the connection end of the curve segment c2 1082 and the curve segment c3 1083 and the center C of the third cam 108 is Lc2. When the third protrusion moves relative to the third cam 108 in the curve segment c2 1082 and has not reached the intersection between the curve segment c2 1082 and the curve segment c3 1083, the third push rod 109 is located in the first working range, pushing the third rotating member 823 to make the front right sliding seat 85 move along the front right sliding groove, and the front right density triangle 77 moves within the density adjustment range, which can adjust the density of the front left needle triangle 73, and the front rubber triangle 78 is in the flush position.

The distance between the end of curved segment c3 1083 and the center C of the third cam 108 is Lc3, where Lc3>Lc2>Lc1. As the third projection moves toward the end relative to the third cam 108 in curved segment c3 1083, the third push rod 109 moves from the first working position to the second working position, and the distance between the front right density cam 77 and the front elastic cam 78 gradually increases. This occurs until the third projection moves relative to the third cam 108 to the end of curved segment c3 1083, and the third push rod 109 reaches the second working position.

[0190] Specifically, a fifteenth return spring is provided between the back of the rear pressure needle triangle 124 and the back of the rear bottom plate body 111, and a sixteenth return spring is provided between the rear right density triangle 117 and the back of the rear bottom plate body 111.

[0191] Specifically, the rear triangle bottom plate is also equipped with a rear left return needle assembly, which includes a rear left return needle triangle 121 and a rear left blocking triangle 120. The rear left blocking triangle 120 is located above the rear left return needle triangle 121, and a rear left return needle path is formed between the two.

The two sides of the rear left return needle surface 1211 are connected with a third guide surface and a fourth guide surface, the third guide surface is tilted upward, and the fourth guide surface is tilted downward. The rear left intercepting cam 120 includes a rear left intercepting needle surface, and the two sides of the rear left intercepting needle surface are connected with a third guide surface and a fourth guide surface, the third guide surface is tilted downward, and the fourth guide surface is tilted upward; thereby, some knitting needles will be loose due to inertia and the looseness of the needle groove The tightness and strength of the yarn tension will cause the needle to be strung up and down, so that the height of the needle butt will be lower than or higher than the rear left return needle surface 1211, so that the needle butt will move to the rear left return needle surface 1211 under the guidance of the third guide surface or the third guide surface; when the needle butt moves from right to left relative to the rear triangle bottom plate, due to the adjustment of the rear left density triangle 112, the height of the needle butt will be lower than or higher than the rear left return needle surface 1211, and the needle butt will move to the rear left return needle surface 1211 under the guidance of the fourth guide surface or the fourth guide surface. Preferably, the inclination angle of the third guide surface is set to 30-60°, and the inclination angle of the fourth guide surface is set to 30-60°. The inclination angle of the third guide surface is shown in A, and the inclination angle of the fourth guide surface is shown in B. Because the angle is too small, the butt of the knitting needle is better protected, but the knitting stroke is too long. When the angle is too large, the knitting stroke is short, but when the cam device moves horizontally quickly, the downward pressure on the butt of the knitting needle is small, and the lateral force is large, which will cause needle punching and serious wear problems. Therefore, the above scheme can effectively protect the butt of the knitting needle, extend its service life and shorten the knitting stroke to a certain extent. In this embodiment, the inclination angles of the third guide surface and the fourth guide surface are set to 45°.
