Abstract
Description
Technical Field
[0001] This utility model belongs to the field of knitting machinery technology, and relates to a novel transfer needle and a novel transfer needle assembly. Background Technology
[0002] In sock production, semi-finished socks are typically produced first in the cylinder of a sock knitting machine. At this stage, the toes of the socks are not sewn shut. A transfer device then removes the semi-finished socks from the cylinder and transfers them to a sewing plate, where a sewing machine sews the toes shut. The transfer device includes transfer needles mounted on the transfer plate. As the transfer needles reciprocate along their axis, they work in conjunction with the vertical needles of the sock knitting machine to transfer the yarn.
[0003] However, existing transfer needles are prone to positional deviations during axial movement due to poor positioning accuracy and precision control, or external influences such as the driving method. This seriously affects product quality, increases the defect rate, increases equipment and material consumption, and requires frequent shutdowns for adjustments, resulting in decreased production efficiency. Summary of the Invention
[0004] The purpose of this invention is to address the above-mentioned problems by providing a novel transfer needle.
[0005] Another objective of this invention is to provide a novel transfer needle assembly.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A novel transfer needle includes a horizontal needle body and a hook tongue disposed at the front end of the horizontal needle body. The horizontal needle body is provided with a return force application part, and the top of the horizontal needle body is provided with a slider for suspending and restricting the horizontal needle body to move only horizontally along the axial direction. The horizontal needle body is also provided with a force receiving part that can drive the horizontal needle body to move along its axial direction when it is subjected to force.
[0008] The slider at the top of the horizontal needle body restricts the horizontal needle body to move only horizontally along its axis. This ensures that no other positional deviations occur during the movement of the horizontal needle body along its axis, thereby achieving precision control. This facilitates precise control of the position of the horizontal needle body, ensures accurate operation, reduces operational complexity, lowers the risk of errors, and guarantees the quality and efficiency of sock thread transfer operations.
[0009] In the aforementioned novel transfer needle, the slider is fixed to the horizontal needle body via a tenon and mortise structure;
[0010] Alternatively, the slider and the horizontal needle body can be fixed by welding or bonding;
[0011] Alternatively, the slider and the horizontal needle body are integrally formed.
[0012] In the aforementioned novel transfer needle, the tenon and mortise structure includes a tenon provided on one end of the slider, the force-bearing part is located on the rear end of the horizontal needle body, the tenon is fitted onto the force-bearing part, and after being fitted, the slider can be axially moved so that one end of it can be inserted into the tenon of the force-bearing part, and the other end of the slider is fixedly connected to the horizontal needle body.
[0013] After the tenon is fitted into the force-bearing part, the slider is moved axially so that one end of the tenon is engaged in the mortise of the force-bearing part. The mortise of the force-bearing part and one end of the tenon cooperate to ensure a stable connection between the slider and the horizontal needle body.
[0014] In the aforementioned novel transfer needle, a reinforcing rib is provided on the side of the force-receiving part away from the mortise, and the reinforcing rib is integrated with the horizontal needle body and the force-receiving part.
[0015] The reinforcing ribs, in conjunction with the tenons, strengthen the connection between the slider and the horizontal needle body, thereby further ensuring a stable connection between them.
[0016] In the aforementioned novel transfer needle, a gap is formed between the tenon and the reinforcing rib, and the reinforcing rib is welded and fixed to the slider and the horizontal needle body within the gap.
[0017] The gap between the tenon and the reinforcing rib facilitates the locking of the mortise and tenon structure. The reinforcing rib is welded and fixed to the slider and the horizontal pin body within the gap, which can ensure the stability of the connection between the slider and the horizontal pin body.
[0018] In the aforementioned novel transfer needle, one end of the slider is fixed to the horizontal needle body by welding, bonding, or snapping.
[0019] One end of the slider is fixed to the horizontal needle body by welding, bonding or snap-fitting to ensure a stable connection.
[0020] In the aforementioned novel transfer needle, the other end of the slider is provided with a slot, and the positioning post at the top of the horizontal needle body passes through the slot. A gap is left between the slot and the positioning post to allow the slider to move axially after the slot is fitted with the positioning post so that the tenon and mortise structure can lock it. The slider, the positioning post, and the horizontal needle body are welded and fixed within the gap.
[0021] The positioning post at the top of the horizontal needle body passes through the slot at the other end of the slider and plays a positioning role by cooperating with the slot. The gap between the slot and the positioning post facilitates the locking of the tenon and mortise structure. The slider, the positioning post and the horizontal needle body are welded and fixed in the gap to ensure a stable connection.
[0022] In the aforementioned novel transfer needle, the force-receiving part includes a protrusion disposed on the rear end of the horizontal needle body.
[0023] When subjected to force, the bump can drive the horizontal needle body to move along its axial direction.
[0024] In the above-mentioned novel transfer needle, the horizontal needle body is sheet-shaped, the maximum width of the slider is greater than the width of the horizontal needle body, one side of the slider is flush with the side of the horizontal needle body, and the other side protrudes from the side wall of the horizontal needle body.
[0025] Alternatively, both sides of the slider protrude from the sidewalls of the horizontal needle body.
[0026] One side of the slider is flush with the side of the horizontal needle body, and the other side protrudes from the side wall of the horizontal needle body. The cross-section of the slider and the horizontal needle body is inverted L-shaped. Both sides of the slider protrude from the side walls of the horizontal needle body, and the cross-section of the slider and the horizontal needle body is T-shaped.
[0027] In the aforementioned novel transfer needle, the opening and force-receiving part of the hook tongue are both located at the top of the horizontal needle body, and a clearance groove is provided on the outer end of the hook tongue; the return force-applying part is located on the rear end of the horizontal needle body.
[0028] The relief groove on the outer end of the hook tongue makes it easier for the loop on the knitting needle to enter the traction surface of the hook tongue when the hook tongue approaches the knitting needle.
[0029] A novel transfer needle assembly includes a novel transfer needle and a gripper disc. The gripper disc has a groove extending radially therefrom, and a slider is disposed in the groove. The slider can slide within the groove under the action of an external force applied along the axial direction of the horizontal needle body.
[0030] After being subjected to force, the force-bearing part on the horizontal needle body applies an outward force along the axial direction of the horizontal needle body, and the slider can slide in the groove under the action of the outward force along the axial direction of the horizontal needle body.
[0031] In the aforementioned novel transfer needle assembly, a needle anti-sway groove is provided between the slide and the bottom of the claw disk for accommodating the horizontal needle body and allowing it to move radially along the claw disk.
[0032] The needle anti-sway groove is used to accommodate the horizontal needle and allow it to move radially along the gripper disc. It can effectively prevent the horizontal needle from swaying during the radial movement of the horizontal needle along the gripper disc, so as to achieve precision control and ensure that the position of the horizontal needle does not deviate.
[0033] In the aforementioned novel transfer needle assembly, the rear end of the slide groove is connected to the vertical groove of the claw hand plate, the vertical groove passes through both ends of the claw hand plate, and the force-bearing part passes through the vertical groove and extends to the upper part.
[0034] The force-receiving part cooperates with the vertical groove. After being subjected to force, the force-receiving part slides in the vertical groove and applies a force along the axial direction of the horizontal needle body to the horizontal needle body. The slider can slide in the groove under the action of the applied force along the axial direction of the horizontal needle body.
[0035] Compared with existing technologies, the advantages of this utility model are: the horizontal needle body can only move horizontally along its axis, and there will be no deviation in other positions during the axial movement of the horizontal needle body, so as to achieve precision control, facilitate precise control of the position of the horizontal needle body, ensure accurate operation, reduce the complexity of operation, reduce the risk of error, and ensure the quality and efficiency of sock thread transfer operation.

[0045] Example 1
[0046] like Figures 1-6As shown, a novel transfer needle includes a horizontal needle body 1 and a hook tongue 2 disposed at the front end of the horizontal needle body 1. The horizontal needle body 1 is provided with a return force application part 3. The top of the horizontal needle body 1 is provided with a slider 4 for suspending and restricting the horizontal needle body 1 so that it can only move horizontally along the axial direction. The horizontal needle body 1 is also provided with a force receiving part 5 that can drive the horizontal needle body 1 to move along its axial direction when it is subjected to force.
[0047] In this invention, the force-receiving part 5 on the horizontal needle body 1 can drive the horizontal needle body 1 to move along its axial direction after being subjected to force. The return force-applying part 3 on the horizontal needle body 1 is used to reset the horizontal needle body 1 so that the horizontal needle body 1 moves and resets along its axial direction. During the reciprocating movement of the horizontal needle body 1 along its axial direction, the hook tongue 2 at the front end of the horizontal needle body 1 cooperates with the vertical knitting needle of the sock machine to perform the sock thread transfer operation. Furthermore, the slider 4 at the top of the horizontal needle body 1 can restrict the horizontal needle body 1 to move horizontally along its axial direction only, which can ensure that no other positional deviations occur during the movement of the horizontal needle body 1 along its axial direction, thereby achieving precision control. This facilitates precise control of the position of the horizontal needle body 1, ensures accurate operation, reduces the complexity of operation, lowers the risk of error, and guarantees the quality and efficiency of the sock thread transfer operation.
[0048] Specifically, combining Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the slider 4 is fixed to the horizontal needle body 1 by the tenon structure 6. The tenon structure 6 includes a tenon 7 set on one end of the slider 4. The force-bearing part 5 is located on the rear end of the horizontal needle body 1. The tenon 7 is sleeved on the force-bearing part 5. After being sleeved, the slider 4 can be moved axially so that one end of it can be inserted into the mortise 8 of the force-bearing part 5. The other end of the slider 4 is fixedly connected to the horizontal needle body 1.
[0049] The tenon 7 on one end of the slider 4 is fitted onto the force-receiving part 5 of the horizontal needle body 1. After the tenon 7 is fitted into the force-receiving part 5, the slider 4 is moved axially so that one end of the tenon 7 is inserted into the mortise 8 of the force-receiving part 5. The mortise 8 of the force-receiving part 5 and one end of the tenon 7 cooperate to ensure a stable connection between the slider 4 and the horizontal needle body 1.
[0050] Specifically, combining Figures 2-4 As shown, a reinforcing rib 19 is provided on the side of the force-bearing part 5 away from the mortise 8. The reinforcing rib 19 is integrated with the horizontal needle body 1 and the force-bearing part 5.
[0051] The reinforcing rib 19 can be rectangular, triangular, or diagonally braced. In this embodiment, the reinforcing rib 19 is rectangular and its top end is flush with the top end of the slider 4.
[0052] The reinforcing rib 19 on the force-bearing part 5, in conjunction with the tenon 7 of the slider 4, can strengthen the connection between the slider 4 and the horizontal needle body 1, thereby further ensuring a stable connection between the slider 4 and the horizontal needle body 1.
[0053] Specifically, combining Figures 2-4 As shown, a gap 20 is formed between the tenon 7 and the reinforcing rib 19, and the reinforcing rib 19 is welded and fixed to the slider 4 and the horizontal pin body 1 within the gap 20.
[0054] The gap 20 between the tenon 7 and the reinforcing rib 19 allows the slider 4 to move axially after the tenon 7 is fitted into the reinforcing rib 19 and the force-bearing part 5 so that the tenon structure 6 can be locked. The reinforcing rib 19 is welded and fixed to the slider 4 and the horizontal needle body 1 within the gap 20, which can ensure the stability of the connection between the slider 4 and the horizontal needle body 1.
[0055] Specifically, combining Figure 2 As shown, one end of the slider 4 is fixed to the horizontal needle body 1 by welding, bonding or snapping.
[0056] One end of the slider 4 is fixed to the horizontal needle body 1 by welding, bonding or snapping to ensure a stable connection.
[0057] Specifically, combining Figures 2-4 As shown, the other end of the slider 4 is provided with a slot 9. The positioning post 10 at the top of the horizontal needle body 1 passes through the slot 9. A gap 11 is left between the slot 9 and the positioning post 10 to allow the slider 4 to move axially after the slot 9 is fitted into the positioning post 10 so that the tenon and mortise structure 6 can be locked. The slider 4, the positioning post 10 and the horizontal needle body 1 are welded and fixed in the gap 11.
[0058] The positioning post 10 at the top of the horizontal needle body 1 passes through the slot 9 at the other end of the slider 4 and cooperates with the slot 9 to play a positioning role. The gap 11 left between the slot 9 and the positioning post 10 facilitates the locking of the tenon and mortise structure 6. The slider 4, the positioning post 10 and the horizontal needle body 1 are welded and fixed in the gap 11 to ensure a stable connection.
[0059] Specifically, combining Figure 2 and Figure 3 As shown, the force-receiving part 5 includes a protrusion 12 provided on the rear end of the horizontal needle body 1.
[0060] The protrusion 12 on the rear end of the horizontal needle body 1 can drive the horizontal needle body 1 to move along its axial direction after being subjected to force.
[0061] Preferably, combined with Figure 2 and Figure 4 As shown, the horizontal needle body 1 is sheet-shaped, the maximum width of the slider 4 is greater than the width of the horizontal needle body 1, one side of the slider 4 is flush with the side of the horizontal needle body 1, and the other side protrudes from the side wall of the horizontal needle body 1.
[0062] Alternatively, both sides of slider 4 protrude from the sidewalls of the horizontal needle body 1.
[0063] One side of the slider 4 is flush with the side of the horizontal needle body 1, and the other side protrudes from the side wall of the horizontal needle body 1. The cross-section of the slider 4 and the horizontal needle body 1 is inverted L-shaped; or both sides of the slider 4 protrude from the side walls of the horizontal needle body 1 respectively. The cross-section of the slider 4 and the horizontal needle body 1 is T-shaped. In this embodiment, the cross-section of the slider 4 and the horizontal needle body 1 is T-shaped.
[0064] Specifically, combining Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the opening of the hook tongue 2 and the force-receiving part 5 are both located at the top of the horizontal needle body 1, and a relief groove 13 is provided on the outer end of the hook tongue 2; the return force-applying part 3 is provided on the rear end of the horizontal needle body 1.
[0065] The return force application part 3 includes a return force application half hole 14 provided on the rear end of the horizontal needle body 1. A tension spring is provided in the return force application half hole 14. When the horizontal needle body 1 moves outward axially, the tension spring is pulled outward and deformed, which can apply an axial inward force to the horizontal needle body 1, thereby causing the horizontal needle body 1 to move and reset along its axial direction.
[0066] The relief groove 13 on the outer end of the hook tongue 2 makes it easier for the coil on the knitting needle to enter the traction surface of the hook tongue 2 when the hook tongue 2 approaches the knitting needle.
[0067] like Figures 1-6 As shown, a novel transfer needle assembly includes a novel transfer needle and a claw disk 15. The claw disk 15 is provided with a groove 16 extending radially thereon. The slider 4 is provided in the groove 16. The slider 4 can slide in the groove 16 under the action of an external force applied to the horizontal needle body 1 along the axial direction of the horizontal needle body 1.
[0068] After being subjected to force, the force-bearing part 5 on the horizontal needle body 1 applies an outward force along the axial direction of the horizontal needle body 1, and the slider 4 can slide in the groove 16 under the action of the outward force along the axial direction of the horizontal needle body 1.
[0069] Specifically, combining Figure 1 , Figure 5 and Figure 6 As shown, a needle anti-sway groove 17 is provided between the slide groove 16 and the bottom of the claw hand plate 15 for accommodating the horizontal needle body 1 and allowing it to move radially along the claw hand plate 15.
[0070] The needle anti-sway groove 17 between the slide groove 16 and the bottom of the claw disk 15 is used to accommodate the horizontal needle 1 and allow it to move radially along the claw disk 15. It can effectively prevent the horizontal needle 1 from shaking during the radial movement of the claw disk 15, so as to achieve precision control and ensure that the position of the horizontal needle 1 will not deviate.
[0071] Specifically, combining Figure 1 , Figure 5 and Figure 6 As shown, the cross-sections of the sliding groove 16 and the needle anti-sway groove 17 on the claw hand plate 15 are inverted L-shaped or T-shaped, which are adapted to the slider 4 and the horizontal needle body 1.
[0072] In this embodiment, the cross-sections of the slide groove 16 and the needle anti-sway groove 17 are T-shaped, which are adapted to the cross-sections of the slide groove 16 and the needle anti-sway groove 17.
[0073] Specifically, combining Figure 1 , Figure 5 and Figure 6 As shown, the rear end of the slide groove 16 is connected to the vertical groove 18 of the claw hand plate 15. The vertical groove 18 passes through both ends of the claw hand plate 15, and the force-bearing part 5 passes through the vertical groove 18 and extends to the upper part.
[0074] The force-receiving part 5 of the horizontal needle body 1 passes through the vertical groove 18 and extends to the upper part. The force-receiving part 5 cooperates with the vertical groove 18. After being subjected to force, the force-receiving part 5 slides in the vertical groove 18 and applies an outward force along the axial direction of the horizontal needle body 1 to the horizontal needle body 1. The slider 4 can slide in the slide groove 16 under the action of the outward force along the axial direction of the horizontal needle body 1.
[0075] The working principle of this utility model is as follows: the slider 4 at the top of the horizontal needle body 1 is set in the groove 16 of the claw hand plate 15, the horizontal needle body 1 is set in the needle anti-sway groove 17 of the claw hand plate 15, and the protrusion 12 of the horizontal needle body 1 passes through the vertical groove 18 of the claw hand plate 15 and extends to the upper part.
[0076] After being subjected to force, the protrusion 12 of the horizontal needle body 1 moves radially outward along the claw hand plate 15 within the vertical groove 18, and applies an outward force along the axial direction of the horizontal needle body 1. The slider 4 can move radially outward along the claw hand plate 15 within the sliding groove 16 under the action of the outward force along the axial direction of the horizontal needle body 1, so that the horizontal needle body 1 moves radially outward along the claw hand plate 15 within the needle anti-sway groove 17. When the horizontal needle body 1 moves radially outward along the claw hand plate 15, the tension spring is pulled outward and deformed, which can apply a radial inward force along the claw hand plate 15 to the horizontal needle body 1, thereby causing the horizontal needle body 1 to move and reset along its axial direction. During the radial movement of the horizontal needle body 1 along the claw hand plate 15, the hook tongue 2 at the front end cooperates with the vertical knitting needle of the sock machine to perform the sock thread transfer operation.
