Description

Technical Field

[0001] This utility model belongs to the field of knitting machinery technology, specifically relating to a novel transfer needle and transfer device. Background Technology

[0002] In the sock production process, semi-finished socks are first produced in the cylinder of a sock knitting machine. At this stage, the toes of the socks are not sewn. Then, a transfer device removes the semi-finished socks from the cylinder and transfers them to the sewing head plate. Finally, a sewing machine sews the toes of the socks. The transfer device usually has a transfer needle, which works with the vertical needles of the sock knitting machine during radial movement to transfer the sock yarn.

[0003] Existing transfer needles are prone to instability during movement due to external factors such as vibration; therefore, there is an urgent need in this field to improve the structure of the transfer needle. Summary of the Invention

[0004] Based on the aforementioned shortcomings and deficiencies in the prior art, one of the objectives of this utility model is to at least solve one or more of the aforementioned problems in the prior art. In other words, one of the objectives of this utility model is to provide a novel transfer needle and transfer device that meets one or more of the aforementioned requirements.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0006] A novel transfer needle includes a needle body with a hook tongue at the front end of the needle body. The novel transfer needle also includes a needle seat, which extends along the axial direction of the needle body and is connected to the needle body by at least two tenon and mortise structures. The positions of the tenon and mortise structures are distributed at intervals along the axial direction of the needle body so that the needle body is suspended and connected to the needle seat.

[0007] In the mortise and tenon structure, the direction of the mating of the tenon and the mortise is the axial direction of the tenon body.

[0008] This invention uses at least two mortise and tenon structures to fix the needle body under the needle holder, and the direction of the tenon and mortise joint of the mortise and tenon structure is the axial direction of the needle body, thereby limiting the needle body in the vertical direction of its axial direction and ensuring that the needle body will not detach from the needle holder.

[0009] As a preferred embodiment, the needle body and needle holder are further secured by welding, bonding, or riveting. This further enhances the stability of the connection between the needle body and needle holder.

[0010] As a preferred embodiment, the needle seat and the needle body slide along their axial direction to form a mortise and tenon structure.

[0011] As a preferred embodiment, the front and rear parts of the needle body are respectively provided with lugs, and correspondingly, the needle seat is provided with lug through holes that correspond one-to-one with the lugs;

[0012] Among them, the sides of the lugs have mortises, and the openings of the mortises of the two lugs face the same direction;

[0013] The lugs of the needle body are inserted into the lug through hole of the needle base, and the two tenons are mortised and tenoned with the needle base synchronously by sliding.

[0014] As a preferred embodiment, the needle holder and the needle body form a mortise and tenon structure through the elastic deformation of the needle body.

[0015] As a preferred embodiment, the front and rear parts of the needle body are respectively provided with lugs, and correspondingly, the needle seat is provided with lug through holes that correspond one-to-one with the lugs;

[0016] Among them, the sides of the lugs have mortises, and the openings of the mortises of the two lugs face opposite directions;

[0017] The lugs of the needle body are inserted into the lug through hole of the needle base, and the two tenons are tenoned with the needle base by sliding and elastic deformation of one of the lugs.

[0018] As a preferred embodiment, the needle body has a relief groove to accommodate the elastic deformation of the lug, and the relief groove is located on the back side of the tenon groove of the elastically deformable lug. This facilitates the installation and mating of the needle body and the needle holder.

[0019] As a preferred embodiment, the rear end of the needle body has a driving force receiving part, which is one of the lugs.

[0020] As a preferred embodiment, the rear end of the needle body has a reset force application section. This facilitates connection with the reset drive component of the transfer device to achieve needle body reset.

[0021] This utility model also provides a transfer device, including a claw disk having a groove extending radially therefrom, and a novel transfer needle as described in any of the preceding embodiments, the needle seat being slidably fitted into the groove to allow the needle body to move radially along the claw disk.

[0034] To more clearly illustrate the embodiments of this utility model, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0035] Example 1:

[0036] like Figures 1 to 3 As shown, the novel transfer needle of this embodiment includes a needle body 1 extending in a horizontal direction (i.e., the axial direction of the needle body 1 is horizontal) and a hook tongue 2 provided at the front end of the needle body 1. A reset force application part 3 is provided at the rear end of the needle body 1. A needle seat 4 is provided at the top of the needle body 1 for suspending and restricting the needle body 1 so that it can only move horizontally in the axial direction. The needle seat 4 extends along the axial direction of the needle body. A drive force receiving part 5 is also provided on the needle body 1, which can drive the needle body 1 to move horizontally in the axial direction when it is subjected to force.

[0037] In this embodiment, the driving force receiving part 5 on the needle body 1 can drive the needle body 1 to move horizontally along its axis after being subjected to force. The reset force applying part 3 on the needle body 1 is used to reset the needle body 1 so that the needle body 1 moves and resets along its axis. During the reciprocating movement of the needle body 1 along its axis, the hook tongue 2 at the front end of the needle body 1 cooperates with the vertical knitting needle of the sock machine to perform the sock thread transfer operation. Furthermore, the needle seat 4 at the top of the needle body 1 can restrict the needle body 1 to move horizontally along its axis, which can ensure that no other positional deviation occurs during the movement of the needle body 1 along its axis, so as to achieve precision control, facilitate precise control of the position of the needle body 1, ensure accurate operation, reduce the complexity of operation, reduce the risk of error, and ensure the quality and efficiency of the sock thread transfer operation.

[0038] In this embodiment, the needle body 1 is suspended and fixed under the needle base 4 by two mortise and tenon structures 6. The positions of the two mortise and tenon structures are distributed at intervals along the axial direction of the needle body, and the mating direction of the tenon and the mortise groove of the mortise and tenon structure is the axial direction of the needle body. This design can realize the movement limit of the needle body and the needle base in the horizontal direction, as well as the movement limit of the needle body and the needle base in the vertical direction, ensuring the stability of the fixed connection between the needle body 1 and the needle base 4.

[0039] Specifically, the front and rear parts of the needle body 1 have vertically extending front lugs 11 and rear lugs 12, respectively. Correspondingly, the needle base 4 has front lug through holes 41 and rear lug through holes 42, each corresponding to a lug. The rear sides of the front lugs 11 and 12 are respectively provided with front tenons 110 and rear tenons 120, with the openings of the front tenons 110 and 120 facing the same direction, i.e., towards the rear of the needle body. Furthermore, the front sides of the front lugs 11 and 12 each have guide ramp structures X, which facilitate the assembly of the needle body 1 and the needle base 4 and also serve as reinforcing ribs. The rear lug 12 is integrated with the driving force-receiving part 5, enabling the needle body 1 to move along its axial direction after being subjected to force.

[0040] The front lug 11 and rear lug 12 of the needle body are respectively inserted into the front lug through hole 41 and the rear lug through hole 42 of the needle seat, and the front lug 11 and the rear lug 12 can move in the front lug through hole 41 and the rear lug through hole 42 respectively. Through the relative sliding between the needle body and the needle seat, the front tenon 110 and the rear tenon 120 are simultaneously tenoned with the needle seat 4. Specifically, they are tenoned with the needle seat 4 behind the front lug through hole 41 and the rear lug through hole 42 respectively. That is, the needle seat part area behind the front lug through hole 41 and the rear lug through hole 42 respectively serves as tenon, thus obtaining two mortise and tenon structures 6.

[0041] In this embodiment, the needle body 1 is sheet-shaped, and the needle seat 4 is a long rectangular parallelepiped structure. The maximum width of the needle seat 4 is greater than the width of the needle body 1. The two sides of the needle seat 4 protrude from the side walls of the needle body 1, forming a T-shaped structure.

[0042] In this embodiment, the opening of the hook tongue 2 is located at the top of the needle body 1, and a relief groove 20 is provided at the front end of the hook tongue 2. The design of the relief groove 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.

[0043] The reset force application part 3 of this embodiment includes a return force application half hole 30 provided on the rear end of the needle body 1. A tension spring can be provided in the return force application half hole 30, similar to the ring tension spring in the lip seal, and the specific details can be found in the prior art. When the needle body 1 moves outward along its axis, the tension spring is pulled outward and deformed, which can apply an axial inward reset force to the needle body 1, thereby causing the needle body 1 to move and reset along its axis.

[0044] like Figure 4 As shown, the transfer device of this embodiment includes a claw disk 15 and a plurality of novel transfer needles arranged in an array along its circumference. The claw disk 15 has a radially extending groove 16 and a needle anti-sway groove 17. The groove 16 is slidably connected to the needle seat 4 of the novel transfer needle. The needle seat 4 can slide within the groove 16 under the action of an external force applied along the axial direction of the needle body 1. The needle anti-sway groove 17 is used to accommodate the needle body 1 and allow it to move radially along the claw disk 15, which can effectively prevent the needle body 1 from swaying during radial movement along the claw disk 15, so as to achieve precision control and ensure that the position of the needle body 1 does not deviate. The groove 16 and the needle anti-sway groove 17 are connected and adapted to the structure of the needle seat 4 and the needle body 1, respectively, and also form a T-shaped structure.

[0045] In addition, the claw hand plate 15 has stroke avoidance strip grooves that match the front lug 11 and rear lug 12 of the needle body respectively at the top of the front end and the rear end of the slide groove 16. The stroke avoidance strip groove 18 that matches the rear lug 12 runs through the upper and lower sides of the claw hand plate 15, which makes it easier for the driving force receiving part 5 to be forceped after insertion.

[0046] The driving force receiving part 5 of the needle body 1 passes through the travel avoidance strip groove 18 and extends to the upper part. After being subjected to force, the driving force receiving part 5 slides in the travel avoidance strip groove 18 and applies an outward force along the axial direction of the needle body 1 to the needle body 1. The needle seat 4 can slide in the slide groove 16 under the action of the outward force along the axial direction of the needle body 1.

[0047] The assembly and operation process of the transfer device in this embodiment is as follows: The needle seat 4 at the top of the needle body 1 is set in the slide groove 16 of the claw hand plate 15, the needle body 1 is set in the needle anti-sway groove 17 of the claw hand plate 15, the driving force receiving part 5 of the needle body 1 passes through the stroke avoidance strip groove 18 of the claw hand plate 15 and extends to the upper part; after being subjected to force, the driving force receiving part 5 of the needle body 1 moves radially outward along the claw hand plate 15 in the stroke avoidance strip groove 18, the needle seat 4 moves radially outward along the claw hand plate 15 in the slide groove 16, and the needle body 1 moves radially outward along the claw hand plate 15 in the needle anti-sway groove 17. When the needle body 1 moves radially outward along the claw hand plate 15, the tension spring deforms and can apply a restoring force radially inward along the claw hand plate 15 to the needle body 1, thereby causing the needle body 1 to move and reset along its axial direction. During the radial movement of the 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.

[0048] Example 2:

[0049] The difference between the novel transfer pin in this embodiment and that in Embodiment 1 is that the position of the tenon groove is different;

[0050] like Figures 5 to 7 As shown, the front and rear parts of the needle body have vertically extending front lugs 11' and rear lugs 12', respectively. Correspondingly, the needle base has front lug through holes 41' and rear lug through holes 42' that correspond one-to-one with each lug. Front lugs 11' and rear lugs 12' are respectively provided with front tenons 110' and rear tenons 120', with the openings of the front tenons 110' and rear tenons 120' facing the same direction, i.e., both facing the front of the needle body. In addition, the rear side of the front lug 11' has a guide ramp structure X', which facilitates the assembly of the needle body and the needle base and also serves as a reinforcing rib. The driving force-receiving part 5' can drive the needle body to move along its axial direction after being subjected to force.

[0060] The transfer device in this embodiment uses the novel transfer needle of this embodiment;

[0061] Other structures can be found in Embodiment 1, Embodiment 2 or Embodiment 3.
