Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle processing, in particular to a feeding device for preventing material sticking in plastic particle processing. Background Technique

[0002] Plastic particles are formed by mixing and extruding a variety of powder and granular materials. After the various materials are evenly mixed, it is convenient to improve the overall performance of the plastic particles. When mixing various materials, a feeding device is required for feeding.

[0003] The Chinese patent discloses an intermittent anti-sticking feeding device for plastic particle processing, with the publication number CN111055471B, which includes a detachable feeding cylinder. A bearing plate is arranged on the inner wall of the detachable feeding cylinder, and a plug is inserted on the surface of the bearing plate. The plug is fixed at the bottom end of the driving shaft of the driving motor, and the driving motor is fixed inside the frame. A collar is sleeved on the outer wall of the frame, and a guiding groove is opened on the bottom surface of the collar; the beneficial effect is that: the intermittent anti-sticking feeding device for plastic particle processing proposed by the present invention is provided with a plug in the material conveying port. The plug can rise synchronously with the stirring structure. When feeding is required, the plug is pulled up to separate the plug from the material conveying port. When the material conveying port needs to be closed, the plug is pushed down to insert into the material conveying port. Since the plug is composed of two frustum cones and cooperates with the spiral plate to reduce the resistance during movement, and the blockage at the material conveying port is avoided.

[0004] However, it still has the following disadvantages: the device horizontally stirs the raw materials through the paddle and the material deflecting plate to mix the raw materials. However, the density of different raw material particles is different, which may cause the raw materials to be stratified up and down, resulting in insufficient mixing of the raw materials. For this reason, we propose a feeding device for preventing material sticking in plastic particle processing to solve this problem. Content of the Utility Model
