[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Existing technologies often suffer from the problem of slowed-down production rates due to difficulties in safely and conveniently collecting stamped hooks. This embodiment addresses this issue by providing a hook stamping device for circular looms. Please refer to [link / reference needed]. Figures 1-5 This device automatically and safely collects stamped hooks, thereby improving the production quality and stamping speed of the hooks. The circular knitting machine hook stamping device includes a stamping table 1 and a needle mold 2. The needle mold 2 is located at the top of a collecting cover 41, facilitating the accumulation of hooks inside the collecting cover 41. The stamping table 1 is equipped with a stamping mechanism 3 for fixing the needle mold 2, and a material collection and protection mechanism 4 for collecting the hooks. The stamping mechanism 3 can fix the mold, thereby improving the stability of the stamping process. The material collection and protection mechanism 4 can safely and conveniently collect the stamped hooks, improving the production efficiency of the hooks and reducing the labor intensity of the workers.

[0028] The existing stamping equipment has poor hook collection efficiency, with hooks scattering on the worktable after stamping and requiring manual collection of each piece. This is not only labor-intensive and time-consuming, but manual operation can also damage the hooks, affecting product quality and performance. To solve the above problems... The material collection and protection mechanism 4 includes a collection cover 41 installed on the stamping table 1. The top of the collection cover 41 has a needle groove with the same shape as the needle mold 2, which facilitates the hook needles to fall from the needle groove into the collection cover 41, thus improving the production efficiency of the hook needles. An electric push rod 42 is installed on the rear side of the collection cover 41. The output end of the electric push rod 42 is equipped with a push plate 43 that is adapted to the inside of the collection cover 41. The bottom end of the push plate 43 abuts against the bottom end of the inside of the stamping table 1, so that the stamped hook needles can be pushed out of the collection cover 41 for easy collection. Dust suction heads 44 are installed on both sides of the stamping table 1. The dust suction heads 44 are symmetrically distributed on both sides of the needle mold 2, which plays a certain role in dust removal. A protective plate 45 is installed on the rear side of the stamping table 1. A sound insulation plate 46 is installed inside the protective plate 45. After the stamping structure completes the stamping of the hook needle, the hook needle falls from the needle groove into the collection cover 41 due to gravity. Then, under the extension and retraction of the electric push rod 42, the push plate 43 pushes the fallen hook needle out of the collection cover 41, thus safely collecting the hook needle and providing a certain level of safety. In addition, the protective plate 45 and the internal sound insulation plate 46 play a protective and noise reduction role, improving the stamping environment. By connecting the dust suction head 44 to a vacuum cleaner, dust can be absorbed and eliminated, which has a certain level of practicality.

[0029] Example 2

[0030] Based on Example 1, such as Figures 1-5 As shown, the existing technology does not allow for safe and convenient collection of stamped hooks, which reduces the production rate of hooks. However, most existing stamping devices use simple bolts to fasten the hook mold. During the stamping process, the mold is prone to displacement due to impact force, resulting in stamping position deviation. The dimensional accuracy of the produced hooks is difficult to guarantee, affecting the production quality of hooks. Therefore, this device is also equipped with a structure to stabilize the mold.

[0031] Existing stamping equipment often uses simple bolts to fasten hook needle dies. During the stamping process, the die is displaced by impact force, causing the stamping position to deviate, making it difficult to meet hook needle size standards and ensuring product quality. To solve these problems, the stamping mechanism 3 includes a cylinder 31 mounted on the top of the stamping table 1. A connecting plate 32 is mounted on the bottom of the cylinder 31, and a needle with the same shape as the needle groove on the needle die 2 is movably mounted on the bottom of the connecting plate 32, facilitating the stamping of hook needles of different sizes. A support rod 33 is mounted on the top of the connecting plate 32, penetrating the top of the stamping table 1. The support rods 33 are symmetrically distributed on both sides of the cylinder 31, improving the stability of the stamping process. The buffer component 34 consists of multiple sets of buffer springs and abutment rings, with the abutment rings made of silicone material, thus giving the entire device a certain buffering effect. This improves the stamping effect. A buffer 34 is installed on the support rod 33, and clamping claws 35 are installed on both sides of the bottom end of the connecting plate 32. An arc-shaped groove adapted to the slide rod 36 is opened on the inner side of the clamping claw 35, so that the needle mold 2 can be smoothly limited and fixed, improving the stability of stamping. The slide rod 36 is slidably connected to the side of the stamping table 1. A compression spring 37 connected to the stamping table 1 is connected to the outer end of the slide rod 36. A support 38 is installed on the bottom inner side of the stamping table 1. A linkage block 39 connected to the inner end of the slide rod 36 is slidably connected to the support 38. With the operation of cylinder 31 and supported by support rod 33 and buffer 34, connecting plate 32 can be raised and lowered stably, which initially improves the stability of stamping. During the descent of connecting plate 32, clamping claw 35 descends, which causes linkage block 39 to move laterally under the limiting support of support 38, slide rod 36 and compression spring 37, thereby synchronously limiting and fixing needle mold 2, further improving the production stability of hook needle.
