Description

Technical Field

[0001] This utility model relates to the field of plastic granulation technology, and in particular to an engineering plastic granulator with rapid cooling function. Background Technology

[0002] An engineering plastics granulator is a mechanical device used to process engineering plastic raw materials into granular products. Through heating, pressurization, and shearing, the engineering plastic raw materials are melted and plasticized in the barrel, and then extruded into strips or filaments through a die. After cooling and pelletizing, they are made into granules with certain specifications and shapes. The core parts of the plastic granulator are the screw and the barrel. The screw rotates in the barrel, conveying the plastic raw materials forward and compressing, melting, and mixing them. The barrel is usually equipped with heating and cooling devices to control the temperature of the plastic at different stages.

[0003] Existing engineering plastic granulators often encounter problems such as poor cooling, excessively high granule surface temperature, and high humidity in the production environment. These factors cause plastic granules to stick together or clump during collection and storage, affecting not only the flowability and dispersibility of the granules but also clogging the feed into subsequent processing equipment. Therefore, the current improvement method is to combine spray cooling with air cooling to ensure that the temperature of the plastic granules drops evenly during the cooling process, avoiding granule deformation or performance differences caused by uneven cooling. However, this design leads to an increase in equipment size, increased installation and debugging difficulty, and higher requirements for granule surface quality and energy consumption.

[0038] Working principle: After the motor 310 is started, the belt pulley transmission mechanism 212 starts to rotate, which drives the gear 13 to rotate.

There is a fixed plate 9 inside the roller 26. When the plastic extruded into strips enters the roller 26, it will be driven by the rotation of the roller 26, thus achieving rapid cooling.

[0039] When the granulator is working, the melted plastic is stirred inside the barrel 3. A lot of plastic will stick to the inner wall of the barrel 3, affecting the quality of the plastic. Therefore, after the motor 202 is turned on, it will drive the belt pulley transmission mechanism 210, which will drive the transmission shaft 204, gear set 205, rotating rod 206, and screw 209 to rotate. There is a scraper 207 on the outside of the screw 209, so the plastic on the inner wall of the barrel 3 can be scraped off during the granulation process.
