Granulator

Abstract

The granulator comprises a granulator lower shell and a granulator upper shell which are distributed up and down, the granulator upper shell is fixedly installed on the upper surface of the granulator lower shell, a conveying structure and a granulating device are distributed in the granulator upper shell in a front-back mode, and a feeding port is formed in the side wall of the front face of the granulator upper shell. A cover plate is arranged on the upper surface of the granulator upper shell, and a rotating shaft is rotationally connected between the cover plate and the granulator upper shell. Through the conveying structure and the pelletizing device, when the TPEE strip feeding device is used, the first driving motor is started, the first driving motor can drive the second connecting shaft and the second conveying roller to rotate, then a TPEE strip is stuffed between the first conveying roller and the second conveying roller along the feeding plate, and due to the fact that the pressure spring can apply pressure to the second conveying roller close to the first conveying roller, the TPEE strip can be cut into the second conveying roller. Therefore, the second conveying roller and the first conveying roller can be used for conveying and limiting the TPEE strips, so that the situation that the uniformity of TPEE particles is low due to the fact that the TPEE strips deviate in the pelletizing process is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of pelletizers, in particular to a pelletizer. Background Art

[0002] Thermoplastic polyester elastomer (TPEE), also known as polyester rubber, is a type of linear block copolymer containing PBT (polybutylene terephthalate) polyester hard segment and aliphatic polyester or polyether soft segment. TPEE combines the excellent elasticity of rubber and the easy processing of thermoplastics. It has adjustable hardness and design freedom. It is a new variety of thermoplastic elastomer that has attracted much attention.

[0003] During the production process, the molten material of TPEE is plasticized by an extruder and then formed into the desired shape by a mold. In order to obtain granular TPEE, the formed material is sent to a pelletizer and cut into particles of uniform size by a rotating blade or cutting device.

[0004] At present, due to the large elasticity of TPEE bars during the pelletizing process, when a pelletizer is used to pelletize TPEE bars, the TPEE bars are prone to deviation, resulting in low uniformity in the size of the finished TPEE particles.

[0005] Therefore, in response to the above problems, we propose a pelletizer. Utility Model Content
