When processing plastics, it is necessary to lift and transport the granular ingredients of various plastics to the processing equipment through a spiral feeder for processing. The granular ingredients are placed in the hopper, and the rotating column drives the spiral blade to rotate, thereby lifting and transporting the plastic ingredients, and then out through the discharge pipe into the processing equipment for processing. The Chinese patent application number is 202320755927.0, which discloses a feeding mechanism for plastic granule processing. It can be seen that the content describes a plastic processing ingredient feeding mechanism.

[0025] See also Figure 1-Figure 7The utility model provides a technical solution: a plastic processing batching feeding mechanism, including a bottom plate 100, a hopper 101, a cylinder 102 and a discharge pipe 103, the cylinder 102 is provided with a feed port and a discharge port, the discharge pipe 103 is connected with the discharge port, the discharge pipe 103 is fixed on the cylinder 102, a rotating column 104 is provided inside the cylinder 102, a spiral blade 105 is fixedly provided outside the rotating column 104, a protective component is provided on the inner wall of the cylinder 102, the protective component includes a protective member and two sets of fixing members, the protective member The protective tube 204 includes a protective tube 204 and two groups of limiting rods 202. When in use, the protective tube 204 can protect the inner wall of the cylinder 102. The outer wall of the protective tube 204 is provided with two groups of arc grooves 205. The limiting rods 202 can be embedded in the arc grooves 205. The fixing parts include an L-shaped plate 201 and a side block 203. The limiting rods 202 are fixed to the inner wall of the cylinder 102. The bottom of the protective tube 204 penetrates into the interior of the cylinder 102. The interior of the L-shaped plate 201 is provided with a threaded opening. When in use, the screw 200 is connected to the threaded opening by a thread. The screw 200 is arranged inside the threaded opening, and the working end of the screw 200 extends to the surface of the side block 203. The screw 200 is connected to the threaded opening by a thread. The side block 203 is fixed on the protective tube 204, and the L-shaped plate 201 is fixed on the cylinder 102. The protective tube 204 is provided with a lower opening and an upper opening inside. The lower opening is connected to the feed port, and the upper opening is connected to the discharge port. When in use, the ingredients in the hopper 101 enter the protective tube 204 through the feed port and the lower opening, and then are discharged from the upper opening and the discharge port through the discharge pipe 103. It can be seen that through the designed protection component, the protection tube 204 is installed on the inner wall of the cylinder 102 during use. When the rotating spiral blades 105 lift and transport the granular ingredients of the plastic, it can play a protective effect. The granular ingredients directly contact the inner wall of the protection tube 204, and the protection effect is played through the protection tube 204, which prevents the granular ingredients from directly contacting the inner wall of the cylinder 102 and causing wear on the inner wall of the cylinder 102, thereby reducing the probability of the cylinder 102 becoming thinner and the strength reduced, making it convenient to use the spiral feeder.

[0026] In the present embodiment, preferably, an internal threaded ring 302 is fixedly provided on the inner wall at the top of the cylinder 102, and an external threaded disk 300 is threadedly connected to the inner wall of the internal threaded ring 302, and a handle 301 is fixedly provided on the top of the external threaded disk 300.

[0027] In this embodiment, preferably, the cylinder 102 is fixed on the hopper 101 and the bottom plate 100 , and a reduction motor is fixedly provided on the bottom plate 100 .

[0028] The working principle and use process of this utility model:

[0029] When the utility model is in use, the protective tube 204 is placed at a suitable position on the top of the cylinder 102, so that the arc groove 205 on the protective tube 204 is aligned with the top of the limiting rod 202 in the cylinder 102 below, and then the protective tube 204 is moved downward, and then the bottom of the protective tube 204 is inserted into the interior of the cylinder 102, and then the top of the limiting rod 202 is inserted into the arc groove 205 located in the protective tube 204. After the bottom of the protective tube 204 is placed into the interior of the cylinder 102, the screw 200 is rotated in the direction close to the side block 203, and then the working end of the screw 200 contacts and clamps the side block 203, and the protective tube 204 can be fixed. At this time, during use, the granular ingredients will contact the inner wall of the protective tube 204 to avoid direct contact with the inner wall of the cylinder 102. When the protective tube 204 is worn out after being used for a long time, the protective tube 204 can be removed and replaced with a new protective tube 204 according to the above-mentioned reverse principle.

[0030] During use, hold the handle 301 and tighten the external threaded disk 300 into the internal threaded ring 302 on the top inner wall of the protective tube 204. This can prevent the granular ingredients inside the protective tube 204 from splashing out from the top of the protective tube 204 during use. The external threaded disk 300 can be removed by operating according to the reverse principle mentioned above.
