Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to a feeding device for producing high-density antistatic foam particles, belonging to the technical field of feeding devices. Background Art

[0002] Foam board is also called Chevron board and Andy board. Its chemical composition is polyvinyl chloride, also known as foam polyvinyl chloride board. It is widely used in buses, train compartment ceilings, box core layers, etc. The production of foam particles requires a feeding device for foam particle production. In actual use, the existing feeding device for foam particle production is not convenient for staff to clean the inside of the device, which is easy to cause pollution to the foam production. In addition, the current feeding structure lacks a corresponding mixing structure, which greatly limits the feeding efficiency, thereby affecting the production efficiency of the foam.

[0003] Chinese patent application number: CN202022571204.4 discloses a high-pressure pellet feeding device for EPS foam raw materials, including a shell, a top cover is fixedly installed on the top of the shell, a stirring motor is fixedly installed on the top of the top cover, a stirring assembly is fixedly installed on the output end of the stirring motor, a fixed bracket is sleeved and installed on the surface of the shell, a conveying assembly is fixedly installed on the bottom of the shell, a conveying motor is fixedly installed on one side of the conveying assembly, and an electric push rod is fixedly installed on one side of the bottom of the conveying assembly. The upper fixing frame fixedly installed at the bottom of the top cover, the fixing screws equidistantly arranged on both sides of the upper fixing frame are sleeved and installed with the threaded holes equidistantly arranged on both sides of the lower fixing frame fixedly installed at the top of the shell, the fixing screws are tightened to fix the top cover and the shell, and the fixing screws are loosened to separate the top cover from the shell, so that the staff can clean the inside of the device conveniently to avoid contamination of EPS foam production.

[0004] When the device is mixing and stirring the foam, the position of the stirring rod is fixed, and it can only mix and stir the foam particles in the middle, but not the foam particles at the bottom, which leads to uneven stirring. At the same time, the device needs to manually loosen the fixing screws to separate the top cover from the shell and clean the inside of the shell, which is time-consuming and laborious. Therefore, we propose a feeding device for the production of high-density antistatic foam particles. Utility Model Content
