Description

Technical Field

[0001] This invention relates to the field of knitting technology, and more specifically, to a knitting needle assembly having three needle positions: high, low, and no needle. It also relates to a knitting apparatus using the knitting needle assembly. Background Technology

[0002] In the field of knitting equipment, computerized glove machines rely on needle selection mechanisms to control the movement of knitting needles. During the knitting process, the knitting needles need to switch between three needle positions: high, low, and no needle, in order to adapt to the requirements of glove knitting technology.

[0003] Most computerized glove machines currently use a needle selection mode that combines a needle selection roller with a needle selection plate. The outer circumference of the needle selection roller is arranged with needle selection pins of different heights according to the knitting process requirements, with each pin corresponding to a needle selection plate. During operation, the needle selection roller rotates continuously. A high-position needle selection pin can lift the needle selection plate, raising the needle to the high needle position, allowing the needle to enter the corresponding knitting track and complete the knitting. A middle-position needle selection pin can lift the needle selection plate, raising the needle to the low needle position, allowing the needle to enter the corresponding knitting track and complete the knitting. When the needle selection plate is not lifted by the needle selection pin, the needle sinks into the needle groove of the needle bed, disengaging from the cam control and not participating in knitting.

[0004] However, the current needle selection mode, which uses a needle selection roller paired with a needle selection plate, requires the setting of a needle selection roller. On the one hand, the roller has a large volume that limits the miniaturization and simplification of the equipment; on the other hand, the needle selection pin on the needle selection roller is in a fixed state and cannot be flexibly switched, which limits the flexibility of the equipment. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a knitting needle assembly and knitting device with three needle positions: high, low, and no needle. By setting a first platform, a second platform, and a third platform of different heights on the pressure plate, different pressures can be applied to the needle holder, thereby achieving adjustment of the needle height of different positions on the needle holder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A knitting needle assembly with three needle positions (high, low, and no needle) includes a needle bed, a knitting needle, a needle lifter plate, a needle presser plate, and a first pin. The upper end of the needle lifter plate is linked to the knitting needle, and the lower end is provided with an elastic part. The elastic part elastically abuts against the needle bed and can elastically deform toward the needle bed. The needle lifter plate is provided with a needle foot facing away from the needle bed.

[0008] The first pin is laterally disposed on the upper side of the needle bed and fixed relative to the needle bed; the pressure plate is located between the first pin and the first elastic part; the pressure plate includes a pressing part and a limiting part, the pressing part faces and abuts against the first elastic part of the needle ejector, the limiting part faces and abuts against the first pin, the limiting part includes a first platform, a second platform and a third platform distributed sequentially along the length direction of the pressure plate, the first platform, the second platform and the third platform protrude toward the first pin and decrease in a stepped manner;

[0009] The pressure needle plate can slide along the length direction and has a first position, a second position and a third position. The pressure needle plate is abutted against the first pin by the first platform, the second platform and the third platform respectively in the first position, the second position and the third position.

[0010] It also includes a needle selector plate, which is located on the side of the pressure needle plate facing away from the needle bed. The needle selector plate can slide along the length direction, and the upper end of the needle selector plate can abut against and maintain the position of the pressure needle plate.

[0011] It also includes a needle selection mechanism, which includes a needle selector and a lower needle selection triangle. The lower needle selection triangle is provided with a low side protrusion and a high side protrusion on the left and right sides of the needle selector, respectively.

[0012] The needle selection plate is provided with a lower needle selection foot facing away from the needle bed. The lower needle selection foot can abut against the lower needle selection triangle and is guided by the low side protrusion and the high side protrusion. The lower needle selection foot is guided by the low side protrusion, and the needle selection plate is raised and drives the pressure plate to slide to the second position. The lower needle selection foot is guided by the high side protrusion, and the needle selection plate is raised and drives the pressure plate to slide to the third position.

[0013] Furthermore, the height position of the first needle can be adjusted according to the elastic deformation of the first elastic part, and has three height positions; the three height positions are high needle position, low needle position and no needle position; the pressure plate in the first position, the second position and the third position correspond to the no needle position, the low needle position and the high needle position of the first needle, respectively.

[0014] Furthermore, it also includes a second pin, which is laterally disposed on the upper side of the needle bed and fixed relative to the needle bed;

[0015] The pressure needle plate includes a limiting part two, which has a limiting groove one, a limiting groove two and a limiting groove three. The pressure needle plate is engaged and limited by the limiting groove one, the limiting groove two and the limiting groove three at the first position, the second position and the third position respectively.

[0016] Furthermore, it also includes a third pin, which is laterally disposed on the upper side of the needle bed and fixed relative to the needle bed; the pressure plate also includes a limiting part three, and the second pin and the third pin are located between the limiting part two and the limiting part three.

[0017] Furthermore, the adjacent connections of the first platform, the second platform, and the third platform are transitioned by a slope.

[0018] Furthermore, the pressure needle plate is provided with two needle feet facing away from the needle bed;

[0019] It also includes a needle selector plate, which is located on the side of the pressure needle plate facing away from the needle bed. The needle selector plate can slide along the length direction, and the upper end of the needle selector plate can abut against the second needle foot upwards and maintain the position of the pressure needle plate.

[0020] Furthermore, the needle selection plate has a fourth position, a fifth position, and a sixth position within its sliding stroke. The needle selection plate can maintain the pressure plate in the first position, the second position, and the third position, respectively, in the fourth position, the fifth position, and the sixth position.

[0021] Furthermore, it also includes a fifth pin, which is laterally disposed on the upper side of the needle bed and fixed relative to the needle bed. The fifth pin is located between the needle pressing plate and the needle selecting plate. The needle selecting plate includes a guide portion, which abuts against the fifth pin. A rotating groove is provided on the upper side of the guide portion. When the needle selecting plate is in the fourth position, the rotating groove and the fifth pin are fitted together, and the needle selecting plate can deflect around the fifth pin.

[0022] Furthermore, the lower selection needle pin is guided by the low-side protrusion, allowing the selection plate to slide to the fifth position; the lower selection needle pin is guided by the high-side protrusion, allowing the selection plate to slide to the sixth position.

[0023] Furthermore, it also includes a needle lifting triangle and a movable needle clearing triangle. When the needle selection plate is in the fourth position, the lower end of the needle selection plate is linked with the needle lifting triangle.

[0024] When the selected needle plate is in the sixth position and the pressing needle plate is in the third position, the second needle foot of the pressing needle plate is linked with the movable needle clearing triangle to achieve needle clearing.

[0025] The present invention also provides a knitting apparatus, including the above-described needle assembly having three needle positions: high, low, and no needle.

[0026] In summary, the present invention has the following beneficial effects:

[0027] By setting a pressure plate and a first pin, the pressure plate is located between the first pin and the elastic part of the needle ejector plate. The pressure plate can transmit elastic pressure between the first pin and the needle ejector plate, thereby pressing down the needle ejector plate to adjust the needle position height of the needle foot on the needle ejector plate. Moreover, three platforms of different heights are formed at the limiting part of the pressure plate, namely the first platform, the second platform and the third platform. By adjusting the sliding of the pressure plate up and down, the relative position between the limiting part and the first pin can be adjusted. The first platform, the second platform and the third platform can respectively abut against the first pin, thereby forming different elastic pressure states on the needle ejector plate, realizing the switching adjustment of the high needle position, low needle position and no needle position of the needle foot on the needle ejector plate. The traditional needle selection roller can be eliminated, the size of the equipment is reduced and the flexibility of the equipment is improved.

[0028] By setting the needle selector plate, the upper end of the needle selector plate can be linked with the needle foot two of the pressure needle plate. Thus, during the upward movement of the needle selector plate, the pressure needle plate can be driven. By switching the high and low positions of the needle selector plate, the height position of the pressure needle plate can be switched, thereby adjusting the different needle positions of the needle foot one of the needle ejector plate.

[0029] In the needle selection mechanism, the lower needle selection triangle is equipped with two triangular protrusions of different heights: a low-side protrusion and a high-side protrusion. The low-side protrusion and the high-side protrusion can interact with the needle selection plate, thereby driving the needle selection plate to rise to different positions and heights, thus enabling three position states and allowing switching and adjustment between high needle position, low needle position, and no needle position.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] This embodiment discloses a knitting needle assembly with three needle positions: high, low, and no needle. (Refer to...) Figures 1-7 As shown, it includes a needle bed 1, knitting needles 2, needle lifters 3, needle pressers 4, and a first pin 61. The needle bed 1 provides support, and the knitting needles 2, needle lifters 3, and needle pressers 4 are mounted on the needle bed 1. Specifically, several inserts are mounted parallel to each other on the upper side of the needle bed 1, and needle grooves 11 are formed between adjacent inserts.

[0044] Reference Figure 1As shown, in this embodiment, the knitting needle 2, the needle guide plate 3, and the needle presser plate 4 are respectively embedded in the needle groove 11 and are guided and limited by the needle groove 11. The knitting needle 2 is located at the top of the knitting needle assembly and plays the role of knitting; the upper end of the needle guide plate 3 is linked with the knitting needle 2, which can be achieved through the structure of the linkage groove and the linkage block. In this way, the needle guide plate 3 can drive the knitting needle 2 to move up and down to realize the knitting action.

[0045] An elastic part 32 is provided at the lower end of the needle plate 3. The elastic part 32 elastically abuts against the needle bed 1 and can elastically deform toward the needle bed 1 when subjected to pressure.

[0046] Furthermore, the needle ejector plate 3 is provided with a needle foot 31 facing away from the needle bed 1. The needle foot 31 can protrude from the needle groove 11 to form different needle foot heights. By applying different elastic pressures to the elastic part 32 of the needle ejector plate 3, the needle ejector plate 3 can be elastically deformed, thereby adjusting the position and height of the needle foot 31.

[0047] The height of pin 31 can be adjusted according to the elastic deformation of elastic part 32, and has three height positions, namely high pin position (refer to...). Figure 4 ), low needle position (refer to) Figure 5 ) and the needle-free position (refer to Figure 6 The three different needle heights of needle 31 can form three different knitting states. When the needle is not in the exit position, the knitting needle 2 does not participate in the knitting action. When the needle is in the high needle position and the needle is in the low needle position, the knitting needle 2 can be guided and matched with the corresponding triangles respectively, thus having two different needle exit actions to adapt to two different knitting requirements.

[0048] Reference Figure 1 , Figure 2 As shown, the first pin 61 is horizontally disposed on the upper side of the needle bed 1 and fixed relative to the needle bed 1. Specifically, a hole can be made in the insert to allow the first pin 61 to be inserted and fixed, thereby realizing the installation of the first pin 61.

[0049] The upper part of the pressure needle plate 4 is roughly in the shape of a "7". The pressure needle plate 4 is located between the first pin 61 and the elastic part 32, and can transmit pressure load between the first pin 61 and the elastic part 32 of the ejector plate 3.

[0050] The pressure needle plate 4 has a pressing portion 42 and a limiting portion 43 formed on both sides. The pressing portion 42 faces and directly abuts against the elastic portion 32 of the ejector pin plate 3. The limiting portion 43 faces and abuts against the first pin 61. The limiting portion 43 includes a first platform 431, a second platform 432, and a third platform 433 distributed sequentially along the length of the pressure needle plate 4. The first platform 431, the second platform 432, and the third platform 433 protrude towards the first pin 61 and decrease in a stepped manner. The first platform 431 protrudes the most, the third platform 433 protrudes the least, and the second platform 432 is located between the first platform 431 and the third platform 433.

[0051] Furthermore, the adjacent connections of the first platform 431, the second platform 432, and the third platform 433 are transitioned by a slope, thereby enabling the first pin 61 to be guided at the three positions of the first platform 431, the second platform 432, and the third platform 433. The sloped surface enables guided climbing, and the different platform positions abut against the first pin 61 can adjust the pressure of the pressing part 42 on the elastic part 32, thereby adjusting the deformation of the elastic part 32 of the ejector pin 3.

[0052] The pressure needle plate 4 is embedded in the needle groove 11 and can slide along the length direction of the pressure needle plate 4. During the sliding stroke, the pressure needle plate 4 has a first position, a second position and a third position. In the first position, the pressure needle plate 4 is abutted against the first pin 61 by the first platform 431, the second platform 432 and the third platform 433, respectively.

[0053] Specifically, when the pressure needle plate 4 slides to the first position (refer to...) Figure 6 As shown), the first platform 431 of the pressure needle plate 4 abuts against the first pin 61. Moreover, since the first platform 431 protrudes to the maximum extent, it can apply greater pressure to the elastic part 32 of the needle ejector plate 3, thereby allowing the needle foot 31 to be completely embedded in the needle groove 11 and the needle foot 31 to be in the non-needle position.

[0054] When the pressure plate 4 slides to the second position (refer to...) Figure 5 As shown), the second platform 432 of the pressure needle plate 4 abuts against the first pin 61. Since the protrusion of the second platform 432 is slightly lower than that of the first platform 431, the pressure applied to the elastic part 32 of the needle ejector plate 3 is reduced, thereby allowing the needle 31 to be partially exposed outside the needle groove 11. The height of the exposed needle 31 is H2, which is approximately 1.7mm. The needle 31 is in the low needle position.

[0055] When the pressure plate 4 slides to the third position (refer to...) Figure 4As shown), the third platform 433 of the pressure plate 4 abuts against the first pin 61. Moreover, since the third platform 433 protrudes less, the pressure applied to the elastic part 32 of the needle ejector plate 3 continues to decrease, thereby allowing more of the needle 31 to be partially exposed outside the needle groove 11. The height of the exposed needle 31 is H1, which is approximately 3.2 mm. The needle 31 is in the high needle position.

[0056] Furthermore, referring to Figure 1 As shown, in order to limit the pressure plate 4 and the ejector plate 3, a fourth pin 64 is also provided on the needle bed 1. The fourth pin 64 is also fitted with an insert to maintain a horizontal state. After installation, the fourth pin 64 can maintain a relatively fixed state with the needle bed 1.

[0057] The elastic portion 32 of the needle ejector plate 3 passes between the fourth pin 64 and the needle bed 1. The fourth pin 64 can abut and limit the elastic portion 32 of the needle ejector plate 3, thereby limiting the protrusion height of the needle foot 31 of the needle ejector plate 3, that is, limiting the maximum protrusion state of the high needle position. In addition, the fourth pin 64 can also block the upper end of the pressure plate 4, thereby limiting the upward sliding stroke of the pressure plate 4.

[0058] During the sliding motion of the pressure needle plate 4, the first, second, and third positions of the pressure needle plate 4 need to be accurately positioned. In this embodiment, a second pin 62 is also installed on the needle bed 1. Similar to the first pin 61, the second pin 62 is also installed through the insert and remains relatively fixed to the needle bed 1 after installation.

[0059] The pressure needle plate 4 includes a limiting part 2 44, which is specifically located at the lower end of the pressure needle plate 4. The surface of the limiting part 2 44 abuts and matches with the second pin 62, which can limit and guide the operation of the pressure needle plate 4, so that the pressure needle plate 4 can slide along a predetermined trajectory.

[0060] Three limiting grooves, namely 441, 442, and 443, are formed on the pressure needle plate 4, creating three limiting openings on the surface of the limiting part 44. These openings are engaged with the corresponding openings by the second pin 62, thereby accurately positioning the pressure needle plate 4 at its first, second, and third positions and maintaining it precisely in these three positions. The pressure needle plate 4 is respectively limited in its first, second, and third positions by the engagement of the limiting grooves 441, 442, and 443 with the second pin 62.

[0061] Furthermore, in order to maintain the sliding stability of the pressure needle plate 4, a third pin 63 and a fifth pin 65 are provided on the needle bed 1 for guiding and limiting, so that the pressure needle plate 4 can achieve stable sliding.

[0062] Reference Figure 1 , Figure 2 As shown, the third pin 63 and the fifth pin 65 are respectively arranged horizontally on the upper side of the needle bed 1. Similarly, they are also installed through the insert and can be fixed relative to the needle bed 1 after installation.

[0063] The pressure needle plate 4 also includes a third limiting part 45, which forms a clamp-like structure with the second limiting part 44. A limiting guide groove 46 can be formed between the third limiting part 45 and the second limiting part 44. The second pin 62 and the third pin 63 are located between the second limiting part 44 and the third limiting part 45. The second pin 62 abuts against the second limiting part 44 for guidance, and the third pin 63 abuts against the third limiting part 45 for guidance, thereby controlling the pressure needle plate 4 to have a stable movement trajectory.

[0064] Furthermore, the limiting part 3 45 can also undergo elastic deformation, and the limiting part 3 45 can elastically press against the needle bed 1 to maintain the position of the pressure needle plate 4. On the side of the pressure needle plate 4 facing away from the needle bed 1, it can be limited by the fifth pin 65. The fifth pin 65 is in a straight state, which can maintain the smooth sliding operation of the pressure needle plate 4.

[0065] Reference Figure 1 , Figure 2 As shown, a needle foot 41 is provided on the pressure needle plate 4 in the direction away from the needle bed 1. The needle foot 41 can protrude from the needle groove 11. The needle foot 41 is used as the part to be loaded with force. An upward or downward force can be applied to the needle foot 41, which can drive the entire pressure needle plate 4 to slide up and down. It can slide and adjust in the first position, the second position and the third position.

[0066] Reference Figure 1 , Figure 3 As shown, the knitting needle assembly in this embodiment also includes a needle selector plate 5, which is also embedded in the needle groove 11. Furthermore, the needle selector plate 5 is located on the side of the pressure plate 4 facing away from the needle bed 1, and the needle selector plate 5 can slide along its length. The upper end of the needle selector plate 5 can abut against the second needle 41 upwards. During the upward movement of the needle selector plate 5, the upper end of the needle selector plate 5 pushes the pressure plate 4 upwards and can abut against and maintain the pressure plate 4 at the corresponding height position.

[0067] Specifically, the needle selector 5 has a fourth, fifth, and sixth position within its sliding stroke. In the fourth, fifth, and sixth positions, the needle selector 5 can maintain the pressure plate 4 in the first, second, and third positions, respectively. A lower needle selector foot 51 and an upper needle selector foot 52 are provided on the needle selector 5 in the direction opposite to the needle bed 1. Through the interaction and cooperation between the lower and upper needle selector feet 51 and the needle selection mechanism, the needle selector 5 can be moved to the corresponding position. Simultaneously, the needle selector 5 will also move the pressure plate 4 to the corresponding position. The needle ejector 3 will also be affected by the pressure plate 4, switching to a high needle position, a low needle position, or a needle-out position, ultimately achieving the switching between the three needle positions.

[0068] Specifically, refer to Figure 6 As shown, the needle selector 5 is in the fourth position, at which point it is at its lowest point formed by the sliding motion. Correspondingly, the needle presser 4 is in the first position, also at its lowest point of travel. The first platform 431 of the needle presser 4 abuts against the first pin 61. Since the first platform 431 has the greatest protrusion, it can apply significant pressure to the elastic part 32 of the needle ejector 3, allowing the needle foot 31 to be completely embedded in the needle groove 11, and the needle foot 31 to be in the non-needle-out position. At this time, the needle foot 31 of the needle ejector 3 does not engage with the triangular mechanism of the needle selector.

[0069] Reference Figure 5 As shown, the lower needle selection pin 51 of the needle selection plate 5 is pushed upward by the needle selection mechanism, causing the needle selection plate 5 to move upward a certain distance to the fifth position. Simultaneously, the upper end of the needle selection plate 5 presses against and pushes the second needle pin 41 of the pressure plate 4, causing the pressure plate 4 to move to the second position. The second platform 432 of the pressure plate 4 abuts against the first pin 61, reducing the pressure applied to the elastic part 32 of the needle ejector plate 3. This allows the first needle pin 31 to partially protrude from the needle groove 11, with an exposed height of approximately 1.7 mm, placing the first needle pin 31 in the low needle position. At this time, the first needle pin 31 of the needle ejector plate 3 can be linked with the triangle corresponding to the low needle position.

[0070] Reference Figure 4 As shown, the lower needle selection pin 51 of the needle selection plate 5 is pushed upward by the needle selection mechanism, causing the needle selection plate 5 to move upward a certain distance to the sixth position. Simultaneously, the upper end of the needle selection plate 5 presses against and pushes the second needle pin 41 of the pressure plate 4, causing the pressure plate 4 to move to the third position. The third platform 433 of the pressure plate 4 abuts against the first pin 61, further reducing the pressure applied to the elastic part 32 of the needle ejector plate 3. This allows more of the first needle pin 31 to protrude from the needle groove 11, with an exposed height of approximately 3.2 mm, placing the first needle pin 31 in the high needle position. At this time, the first needle pin 31 of the needle ejector plate 3 can be linked with the triangle corresponding to the high needle position.

[0071] Furthermore, the fifth pin 65 is laterally disposed on the upper side of the needle bed 1 and fixed relative to the needle bed 1. Moreover, the fifth pin 65 is located between the needle pressing plate 4 and the needle selecting plate 5. The needle selecting plate 5 can rotate in conjunction with the fifth pin 65. Thus, during the needle selection process, the needle selecting plate 5 can be deflected into the needle groove 11 by the action of the needle selector 73, so that the lower needle selection needle foot 51 is inserted into the needle groove 11, which can keep the needle pressing plate 4 in the first position and keep the needle foot 31 in the non-needle position.

[0072] Reference Figure 1 , Figure 3 As shown, the needle selector 5 includes a guide portion 53, which abuts against the fifth pin 65. The guide portion 53 has a flat structure, which enables the needle selector 5 to slide and guide. Furthermore, a rotating groove 54 is provided on the upper side of the guide portion 53, which can be rotatably adapted to the fifth pin 65.

[0073] Reference Figure 6 , Figure 7 As shown, when the needle selector 5 is in the fourth position and is subjected to the force of the needle selector 73, the lower end of the needle selector 5 can deflect toward the needle groove 11, so that the lower needle selector 51 of the needle selector 5 can be inserted into the needle groove 11 and will not be linked with the corresponding lower needle selector triangle 71. Thus, the needle selector 5 will remain in the fourth position and will not slide upward. At this time, the needle presser 4 remains in the first position, keeping the needle 31 in the non-needle position.

[0074] Example 2

[0075] This embodiment discloses a knitting needle assembly with three needle positions: high, low, and no needle. Based on Embodiment 1, and further referring to... Figure 8 , Figure 9 Please provide a detailed explanation.

[0076] The knitting needle assembly with three needle positions (high, low, and no needle) in this embodiment also includes a needle selection mechanism.

[0077] Reference Figure 8 As shown, the needle selection mechanism is supported by a mountain plate and is laterally slidably installed on the upper side of the needle bed 1, enabling it to slide laterally back and forth.

[0078] The needle selection mechanism includes a needle selector 73 and upper needle selection triangles 72 and lower needle selection triangles 71 located on the upper and lower sides of the needle selector 73. Lower needle selection pins 51 and upper needle selection pins 52 are provided on the needle selection plate 5 facing away from the needle bed 1. The lower needle selection pin 51 works in conjunction with the lower needle selection triangle 71 to lift the needle on the needle selection plate 5 upwards; the upper needle selection pin 52 works in conjunction with the upper needle selection triangle 72 to press the needle on the needle selection plate 5 downwards, thereby switching the needle selection plate 5 to achieve vertical guiding drive.

[0079] The lower needle selection triangle 71 is provided with a low side protrusion 711 and a high side protrusion 712 on the left and right sides of the needle selector 73, respectively. Both the low side protrusion 711 and the high side protrusion 712 are triangular structures. The low side protrusion 711 and the high side protrusion 712 can form different track heights, which can cooperate with the lower needle selection pin 51 and drive the needle selection plate 5 to move from the fourth position to the fifth position or the sixth position, thereby realizing the switching of different needle positions.

[0080] Correspondingly, the upper needle selection triangle 72 is provided with a low side guide groove 721 and a high side guide groove 722. The movement of the low side guide groove 721, the high side guide groove 722 and the upper needle selection needle foot 52 can meet the height of the needle selection plate 5 moving upward.

[0081] Reference Figure 8 , Figure 9 As shown, when the needle selection mechanism moves to the left, during the upward movement of the needle selection plate 5, the lower protrusion 711 of the lower needle selection triangle 71 is linked with the lower needle selection pin 51 of the needle selection plate 5, which can drive the needle selection plate 5 to move upward from the fourth position to the fifth position. Correspondingly, the needle pressing plate 4 moves to the second position, and the pin 31 of the needle lifting plate 3 is in the low needle position. (Refer to...) Figure 5 The state shown.

[0082] Reference Figure 8 , Figure 9 As shown, when the needle selection mechanism moves to the right, during the upward movement of the needle selection plate 5, the high side protrusion 712 of the lower needle selection triangle 71 is linked with the lower needle selection pin 51 of the needle selection plate 5, which can drive the needle selection plate 5 to move upward from the fourth position to the sixth position. Correspondingly, the needle pressing plate 4 moves to the third position, and the pin 31 of the needle lifting plate 3 is in the high needle position. (Refer to...) Figure 4 The state shown.

[0083] Reference Figure 3 , Figure 8 , Figure 9 As shown, the needle selection plate 5 is provided with a needle selection part 55, which corresponds one-to-one with the corresponding cutter head of the needle selector 73. When the needle selector 73 applies a downward pressure force to the needle selection part 55 of the needle selection plate 5, the lower needle selection pin 51 of the needle selection plate 5 does not form a linkage with the lower side protrusion 711 and the higher side protrusion 712 of the lower needle selection triangle 71. The needle selection plate 5 will remain in the fourth state, the needle pressing plate 4 will remain in the first position, and the needle pin 31 of the needle ejector plate 3 will be in the needle-out position. (Refer to...) Figure 6 , Figure 7 The state shown.

[0084] The needle selection mechanism in this embodiment further includes a needle lifting triangle 74 and a movable needle clearing triangle 75. The needle lifting triangle 74 is located between the lower side protrusion 711 and the higher side protrusion 712, and can be linked and adapted to the lower end of the needle selection plate 5. When the needle selection plate 5 passes the needle lifting triangle 74, the lower end of the needle selection plate 5 is linked with the needle lifting triangle 74, and the lower end of the needle selection plate 5 can deflect around the fifth pin 65 toward the needle bed 1. The needle selection plate 5 deflects back to its original position, that is, it deflects inward from the lower end of the needle selection plate 5 and the lower needle selection needle foot 51 is embedded in the needle groove 11 (refer to...). Figure 7 ), to achieve reset.

[0085] The movable needle-cleaning triangle 75 is located above the upper needle-selecting triangle 72, specifically between the lower guide groove 721 and the higher guide groove 722. The movable needle-cleaning triangle 75 can cooperate with the second needle foot 41 of the pressure plate 4, pressing the pressure plate 4 downwards to clean the needle. When the pressure plate 4 passes the movable needle-cleaning triangle 75, the triangle is subjected to downward pressure, allowing it to return from a higher second or third state to the first state, thus achieving needle cleaning reset.

[0086] Furthermore, referring to Figure 10 As shown, the needle selection mechanism in this embodiment also adopts a dual-system structure, with two independent needle selectors 73 installed side by side along the horizontal direction on the cap plate, and two corresponding triangular structures installed in conjunction with them; the two sets of needle selectors 73 and triangular structures are arranged symmetrically from left to right, which can simultaneously control the independent operation of two knitting needle assemblies, thereby improving knitting efficiency.

[0087] This embodiment also discloses a knitting device, including a knitting needle assembly with three needle positions: high, low, and no needle, as described in the above embodiment.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
