Description

Technical Field

[0001] The utility model relates to the technical field of feeding and stirring of injection molding machines, in particular to a feeding and stirring mechanism of an injection molding machine with a dredging effect. Background Art

[0002] The injection molding machine with a feeding and stirring mechanism is an indispensable production equipment in production. Automatically transporting and stirring raw materials during the production process not only improves production efficiency, but also facilitates workers' operation and saves more labor costs for the company. However, the existing injection molding machine feeding and stirring mechanism still has some shortcomings.

[0003] For example, an injection molding machine feeding and stirring mechanism with publication number CN213648425U includes a stirring box, a feeding funnel, a material guide funnel and a spiral blade. The top of the stirring box is fixedly provided with a feeding funnel, and the inside of the feeding funnel is provided with a material discharge plate and a filter screen in sequence from top to bottom. The bottom of the stirring box is fixedly provided with a material guide funnel, and one side of the stirring box is provided with a mounting box, and the inside of the mounting box is fixedly provided with a motor. The output shaft of the motor is fixedly provided with a rotating shaft that penetrates and extends to the stirring box, and the surface of the rotating shaft is fixedly provided with spiral blades located inside the stirring box. In the feeding and stirring mechanism of the injection molding machine, the raw materials enter the stirring box through the feeding funnel, and the motor is used to drive the rotating shaft to rotate, thereby driving the spiral blades to rotate and feed the materials, so as to achieve the purpose of stirring and feeding the materials evenly. The structure is simple, which is conducive to avoiding the phenomenon of raw material blockage, but the following problems still exist:

[0004] 1. The screening device cannot effectively screen the raw materials, and the screening efficiency is low. When the material enters the device, it intermittently screens the raw materials through the action of the spring and the filter. The screening speed is not high, which affects the production efficiency of the equipment. At the same time, as the raw materials are continuously added to the screening device, the gravity borne by the spring becomes greater and greater as the raw materials are added. At this time, the elastic effect of the spring becomes worse, thereby reducing the working efficiency of the filter, and there are certain usage defects.

[0005] 2. A discharge port is arranged at the lower end of the filter screen. The screened raw materials are prone to bridge at the discharge port. As more and more raw materials pass through the filter screen, the raw materials are prone to accidental bridge at the discharge port, blocking the outlet. The spiral blades arranged at the lower end of the outlet cannot transport the raw materials that have bridged at the discharge port, and there are certain defects in use. Utility Model Content

The gear transmission rod is rotatably connected to the upper surface of the pulverizer, and a pulley is fixedly installed at the lower end of the gear transmission rod.
