Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 , this embodiment provides a technical solution: a feeding mechanism for an injection molding machine for producing vinyl, comprising a storage hopper 1 and an anti-blocking component 3;

[0021] Storage hopper 1: A feed pipe 2 is provided at the discharge port at its lower end, and the transported raw materials are poured into the storage hopper 1. Under the guidance of the conical inner arc surface at the lower end of the storage hopper 1, the raw materials pass through the feed pipe 2 into the injection molding machine for the production of enamel rubber, and supply the working material for the injection molding machine of the enamel rubber production. The storage hopper 1 also includes a control switch 7, which is located on the left side of the storage hopper 1. The input end of the control switch 7 is electrically connected to an external power supply to control the start and stop of the anti-blocking component 3.

[0022] The anti-blocking component 3 includes a cylinder 31, a rotating tube 32, a limiting plate 33, a reciprocating slide 34, a top pressure plate 35 and a fixed plate 37. The fixed plate 37 is arranged at the upper end of the interior of the storage hopper 1. The middle part of the fixed plate 37 is provided with a cylinder 31. The inner arc surface of the cylinder 31 is provided with a reciprocating slide 34. The interior of the cylinder 31 is slidably connected to the limiting plate 33. The sliding column on the outer arc surface of the limiting plate 33 is slidably connected to the reciprocating slide 34. The lower surface of the limiting plate 33 is provided with a rotating tube 32. The lower end of the rotating tube 32 passes through the interior of the cylinder 31 and is provided with a top pressure plate 35. The top pressure plate 35 is installed in conjunction with the feed pipe 2. When the rotating tube 32 rotates, the outer surface of the limiting plate 33 The cambered sliding column slides in the reciprocating slide groove 34. Under the guidance of the reciprocating slide groove 34, the limit plate 33 drives the rotating tube 32 and the top pressure plate 35 to move back and forth in the process of self-rotation. When the top pressure plate 35 moves downward, the top pressure plate 35 is inserted from the storage hopper 1 into the feed pipe 2, pushing the raw materials in the storage hopper 1 into the feed pipe 2 accurately; when the top pressure plate 35 moves upward, the top pressure plate 35 leaves the feed pipe 2. In the process of the top pressure plate 35 moving upward in the feed pipe 2, it will drive part of the raw materials at the upper end of the feed pipe 2 to move upward. At the same time, the air vents on the surface of the top pressure plate 35 can ensure smooth flow of air, avoiding the feed pipe 2 from leaking. Negative pressure is generated inside to prevent the accumulation of raw materials from affecting the discharge of raw materials at the lower end of the feed pipe 2, thereby ensuring smooth feeding of raw materials.
