[0002] Fasteners are tools that play a fixing role. Their materials include metal, plastic, etc. In the production process of plastic fasteners, plastic particles are transferred to the injection molding machine through the feeding mechanism, and then the injection molding machine melts the plastic particles. After that, the molten plastic material is injected into the mold and solidified under the action of pressurization and cooling, thus forming a plastic fastener with a specific shape.

However, in actual production, the transmitted plastic particles are uneven in size. If they are not screened, it is easy to affect the quality of subsequent plastic parts and reduce the appearance of plastic parts. In view of this, we propose a material feeding mechanism for a fastener production line. Utility Model Content

A bending rod 402 is fixedly connected to the surface of the screening box 401, a movable rod 403 is fixedly connected to the bottom of the bending rod 402, and a spring 404 is connected to the bottom of the movable rod 403, wherein the movable rod 403 and the spring 404 are engaged in the inside of the machine body 1, and the screening box 401 forms an elastic structure with the machine body 1 through the bending rod 402, the movable rod 403, the spring 404, a fixed plate 405 is provided on the side of the movable rod 403, and the movable rod 403 and the fixed plate 405 are connected by a connecting rod 406. The utility model effectively transmits material particles to the interior of the screening box 401 through the auxiliary inclined frame 2, and the filter at the bottom of the screening box 401 effectively screens the material particles, so that the size of the material entering the injection molding machine is uniform, reducing the impact on the finished injection molded buckle. At the same time, under the influence of the driving mechanism 5 and the spring 404, the screening box 401 effectively performs an up and down circulation motion during the screening process, thereby playing a vibrating role and improving the screening efficiency.

[0027] It is worth noting that the adjustment mechanism 3 includes a fixed leg 301, a hydraulic cylinder is embedded inside the fixed leg 301, a hydraulic rod 302 extends from the movable end of the hydraulic cylinder, a movable leg 303 is connected to the top of the hydraulic rod 302, and one end of the movable leg 303 away from the hydraulic rod 302 is connected to a limiting frame 304, wherein the limiting frame 304 is fixedly connected to the machine body 1, and the limiting frame 304 forms a lifting structure through the movable leg 303, the hydraulic rod 302 and the fixed leg 301. The utility model effectively adjusts the height of the movable leg 303 and the limiting frame 304 through the hydraulic rod 302, thereby adjusting the height of the machine body 1, so that the discharge port at the lower end of the machine body 1 can be adapted to the injection molding machine feed port of different heights, thereby improving the practicality of the device.

[0028] It is worth mentioning that the driving mechanism 5 includes a fixed frame 501, which is fixed to the outer wall of the body 1, and a motor 502 is engaged inside the fixed frame 501. The movable end of the motor 502 is connected to a driving wheel 503, and a driven wheel 504 is provided in front of the driving wheel 503.
