[0001] The utility model relates to the technical field of cables, in particular to a feeding device for a plastic extruder. Background Art

[0002] Cable refers to conductive metal wires and their products used to transmit electrical energy, transfer information and manufacture various motors. A plastic extruder is required for cable processing. Its main function is to heat the plastic or rubber material to a molten state and then extrude it through a mold. When the plastic extruder is in use, a feeding device is required to add plastic particles into the extruder.

[0003] After searching, the patent number is CN207825426U, and the name is a utility model of a plastic extruder feeding device, including a base. Through research and analysis, it is found that although the hydraulic cylinder has the advantage of facilitating the adjustment of the height of the feeding box, there are still the following disadvantages to a certain extent.

[0004] For example, because it does not have the function of controlling the amount of material fed during use, when the material is injected into the extruder, it is easy to feed the material too quickly, resulting in too much material fed, causing the feed port to be blocked, affecting production efficiency, and it does not have the function of screening the material, so when feeding, larger materials will enter the extruder, which is easy to affect the cable production and reduce the quality of the cable. In order to solve the above technical problems, we have designed a plastic extruder feeding device. Utility Model Content

[0023] See also Figure 1 , Figure 2 and Figure 4 The material discharging assembly 3 includes a rotating roller 305, the left and right ends of which are movably connected to the inner wall of the square tube 7 through bearings, a connecting rod 303 is welded to the left end of the rotating roller 305, and the left end of the connecting rod 303 penetrates to the left side of the square tube 7, and the left end of the connecting rod 303 and the left end of the first rotating rod 805 are both fixedly sleeved with a belt pulley 301;

[0024] See also Figure 1 , Figure 2 and Figure 4 The surface of the belt pulley 301 is connected with a belt 302 for transmission. By setting the belt pulley 301 and the belt 302, when the first rotating rod 805 rotates, the connecting rod 303 can drive the rotating roller 305 to rotate, so that the material is quantitatively discharged. The surface of the rotating roller 305 is welded with a partition plate 304;

[0025] See also Figure 2 , Figure 3 and Figure 5 The screening assembly 8 includes a supporting short plate 806. By setting the supporting short plate 806, the connecting spring 802 can be supported, so that the screening mesh plate 801 can squeeze and vibrate the connecting spring 802. One side of the supporting short plate 806 is fixedly connected to the inner wall of the feed shell 1 by bolts. The right side of the feed shell 1 is connected to the second motor 803 by bolts. The left end of the rotating shaft of the second motor 803 passes through the inner cavity of the feed shell 1 and is welded to the right end of the first rotating rod 805. The top of the supporting short plate 806 is welded with the connecting spring 802;

[0026] See also Figure 2 , Figure 3 and Figure 5 , a screening mesh plate 801 is welded to the top of the connecting spring 802, and a cam 804 is fixedly sleeved on the surface of the first rotating rod 805;
