A latch limiting block is also installed on the die holder. The vertical distance between the limiting surface of the latch limiting block and the center of the punching hole at the top of the punching bottom die is the distance from the center of the latch hole of the latch to the top of the latch, so as to solve the technical problems of poor processing quality of the latch in the prior art and easy breakage of the punch.

[0003] However, there are some problems in the prior art: The existing device for manufacturing a latch hole of a latch needle usually fixes the knitting needle on the device and then punches one end of it. The knitting needle is only stressed at the latch, and the stress area of the knitting needle is small, which easily causes deformation or fracture at the latch of the knitting needle. Moreover, the punching efficiency of the device is low and the manufacturing speed is slow. Therefore, we propose a fixing device for manufacturing a latch hole of a latch needle. Content of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a fixing device for manufacturing a latch hole of a latch needle, which simultaneously conveys two knitting needles through a screw rod, thereby increasing the stress area of the knitting needle, avoiding deformation or fracture of the knitting needle, and accelerating the punching rate.

[0005] The utility model is realized as follows: A fixing device for manufacturing a latch hole of a latch needle includes a bracket. A housing is fixedly connected to the bracket.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to further understand the content, features and effects of the present utility model, the following embodiments are cited and described in detail in conjunction with the accompanying drawings as follows.

[0026] As Figures 1 to 5 shown, a fixing device for manufacturing a latch hole of a latch provided by an embodiment of the present utility model includes a support 1, which is welded by multiple groups of steel pipes. The main function of the support 1 is to support the entire device.

[0027] An outer shell 2 is fixedly connected to the support 1. The outer shell 2 is made of stainless steel as a whole and is welded by multiple groups of stainless steel plates. Its main function is to protect various components inside it.

[0028] Two screw rods 3 are rotatably connected to the inner wall of the outer shell 2. The two screw rods 3 are symmetrically arranged. A drive chamber 10 is fixedly connected to one side of the outer shell 2. A first motor 11 is fixedly connected to the inner wall of the drive chamber 10, and the screw rod 3 is fixedly connected to the output end of the first motor 11.

[0029] After the first motor 11 starts, it drives the screw rod 3 to rotate on the outer shell 2, so that the knitting needles on the screw rod 3 can move accordingly.

[0030] A limiting rod 4 is fixedly connected to the inner wall of the outer shell 2. The limiting rod 4 is arranged at the upper end of the screw rod 3. The limiting rod 4 is rectangular and made of stainless steel. The main function of the limiting rod 4 is to block the knitting needles on the screw rod 3 and prevent the knitting needles from falling off the screw rod 3 during the conveying or punching process.

[0031] A needle storage hopper 5 is fixedly connected to one end of the outer shell 2. A needle delivery tube 6 is fixedly connected to the lower end of the needle storage hopper 5. The needle storage hopper 5 is funnel-shaped and made of stainless steel. The main function of the needle storage hopper 5 is to store the unpunched knitting needles. The needle delivery tube 6 fixedly connected below the needle storage hopper 5 is sized to fit the knitting needles, and just allows a single knitting needle to pass through the needle delivery tube 6. Thus, the knitting needles can enter the device downward due to their own gravity through the needle delivery tube 6, and a set of knitting needles is added between every two sets of spirals of the screw rod 3, thereby completing the automatic feeding of the knitting needles.

[0032] A punching assembly 7 is arranged in the middle of the outer shell 2. The punching assembly 7 includes a support rod 701. The support rod 701 is fixedly connected to the inner wall of the outer shell 2. A slideway is provided on one side of the support rod 701, and a pressing plate 702 is slidably connected in the slideway.

[0033] A first hydraulic rod 703 is fixedly connected to the inner wall of the outer shell 2. The pressing plate 702 is fixedly connected to the movable end of the first hydraulic rod 703. A pressing block 704 is movably connected to the lower end of the pressing plate 702.

[0034] When the screw rod 3 conveys the knitting needles to be punched above the mold 9, the first hydraulic rod 703 will extend, driving the pressing plate 702 to slide downward in the slideway on the outer shell 2. The pressing plate 702 then drives the pressing block 704 to move downward, so that the pressing block 704 punches the knitting needles. After that, the first hydraulic rod 703 contracts to retract the pressing block 704. When the next set of knitting needles arrives, the above operation is repeated to punch them.

[0035] A chute is provided at the lower end of the pressing plate 702. The pressing block 704 is slidably connected in the chute. A threaded rod 12 is rotatably connected to the inner wall of the chute. A threaded hole is provided in the middle of the pressing block 704, and the threaded rod 12 is rotatably connected in the threaded hole. A second motor 13 is fixedly connected to one side of the pressing block 704, and the threaded rod 12 is fixedly connected to the output end of the second motor 13.

[0036] After the second motor 13 starts, it drives the threaded rod 12 to rotate. After the threaded rod 12 rotates, it will drive the pressing block 704 to slide in the chute on the pressing plate 702, so that the pressing block 704 changes its position corresponding to the pressing hole on the mold 9, and thus changes the size of the holes punched in the knitting needles.

[0037] At the other end of the outer shell 2, a cutting assembly 8 is provided. The cutting assembly 8 includes a cutting plate 801 which is slidably connected to the outer shell 2. A second hydraulic rod 802 is fixedly connected to the upper end of the outer shell 2, and the cutting plate 801 is fixedly connected to the movable end of the second hydraulic rod 802. A blade 803 is fixedly connected to the middle of the lower end of the cutting plate 801.

[0038] When the knitting needle after punching is moved to below the cutting plate 801 by the screw rod 3, the second hydraulic rod 802 will extend outwards, causing the cutting plate 801 to move downwards, so that the blade 803 moves downwards to cut the knitting needle after punching. After cutting, the second hydraulic rod 802 will contract, causing the cutting plate 801 to move upwards. When the next group of knitting needles moves to below the cutting plate 801, the above operation is repeated to cut the knitting needles.

[0039] In the middle of the inner wall of the outer shell 2, a mold 9 is movably connected. A number of pressing holes of different sizes are provided at the upper end of the mold 9, and the pressing holes correspond to the pressing blocks 704. Different pressing holes can be selected according to the size of the tongue hole of the required knitting needle.

[0040] An outlet is provided on the outer wall of the outer shell 2. A discharge chute 14 is fixedly connected to the inner wall of the outlet. A storage box 15 is fixedly connected to the support 1, and the storage box 15 is located below the discharge chute 14. The cut knitting needles will flow out from the discharge chutes 14 on both sides of the outer shell 2 and be concentrated in the storage box 15 for collection.

[0041] On one side of the support 1, a control console 16 is also fixedly connected. A display screen, control buttons, etc. are fixedly connected to the control console 16. A control unit, electronic circuits, etc. are also provided on the control console 16. The main function of the control console 16 is to control the operation of the entire device.

[0042] The working principle of the present utility model is as follows:

[0043] The present utility model can simultaneously convey two groups of knitting needles to be punched through the screw rod 3. When the knitting needles move above the mold 9, the first hydraulic rod 703 will drive the pressing plate 702 downwards, so that the pressing block 704 moves downwards to press and punch the middle of the knitting needles. In this way, the stress area of the knitting needles increases, avoiding the situation that one end of the knitting needle is subjected to greater force and is prone to deformation or breakage.

[0044] The present utility model uses a screw rod 3 for conveying. The distance of the helix on the screw rod 3 is adapted to the knitting needles, and limiting rods 4 are fixedly connected to the screw rod 3. While the fixed structure is simple, the knitting needles will not easily be displaced or dropped during conveying and punching.

[0045] The utility model is provided with multiple pressing holes of different sizes on a mold 9, and the rotation of a threaded rod 12 can be driven by a second motor 13, so that a pressing block 704 moves. When the pressing block 704 moves to different pressing holes, the sizes of the holes punched by the latch of a knitting needle are different, and the size of the latch hole of the knitting needle can be adjusted according to the needs of the user.

[0046] The utility model can punch two groups of knitting needles simultaneously, and the knitting needles in a needle storage hopper 5 can enter the device orderly and automatically through a needle conveying pipe 6, improving the punching efficiency.

[0047] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
