Description

Technical Field

[0001] The utility model belongs to the technical field of plastic fitting processing, and particularly relates to an extrusion device for plastic fitting processing. Background Technique

[0002] Vehicle fittings refer to each unit that constitutes an entire vehicle and a product for vehicle services. These fittings cover various systems of the vehicle, including but not limited to the braking system, running system, engine system, body accessories, etc. Among vehicle fittings, plastic fittings are an important component. The processing and production of plastic pipes, rods, and plates usually require the use of an extrusion device to form through a die. Before the extrusion device processes plastic fittings, a feeding cylinder is usually used to achieve the feeding of raw materials.

[0003] The utility model patent with the publication number 201621181054.3 discloses a plastic extruder, which includes a processing box, a buffer chamber, and an installation chamber. The processing box is composed of a buffer chamber and an installation chamber. A partition is provided between the installation chamber and the buffer chamber. A transmission cylinder is horizontally arranged in the installation chamber. The left end of the transmission cylinder passes through the partition. A transmission rod is arranged in the transmission cylinder. A driving shaft is arranged at the right end of the transmission rod. The right end of the driving shaft passes through the right side wall of the processing box and is connected to a driving motor. A motor seat is arranged outside the driving motor. A gasket is arranged between the motor seat and the processing box. A feeding hopper is arranged at the upper right end of the processing box. The lower port of the feeding hopper is communicated with the transmission cylinder. An aggregate chamber is arranged at the lower end of the buffer chamber. A first extrusion chamber and a second extrusion chamber are respectively arranged on both sides of the aggregate chamber. The bottoms of the first extrusion chamber and the second extrusion chamber are flush with the bottom of the aggregate chamber. It is simple, reasonable, has good sealing performance, eliminates the problem of material transportation lag existing in the existing device, ensures the processing speed of the device, and has strong practicability.

[0004] According to the above patent, there is an extrusion device for plastic fitting processing. When actually used, there are still disadvantages. The more obvious one is that due to the adhesiveness of plastic raw materials, when the raw materials are fed through the feeding cylinder, they are easily adhered to the inner wall of the feeding cylinder, which is not convenient for cleaning the raw materials on the inner wall of the feeding cylinder, resulting in waste of raw materials and reducing the processing efficiency of the extrusion device. For this reason, we propose an extrusion device for plastic fitting processing. Content of the Utility Model
