Plastic dicing device with good radiation

Abstract

The invention discloses a plastic dicing device with good radiation. The plastic dicing device comprises a cutting room, a rubber roller, a traction roller, a slicer, a conveyer belt, an air blower and an exhaust hood, wherein the rubber roller and the traction roller are arranged in an upper position in the cutting room through a bracket; the rubber roller comprises a steel core and a rubber layer coated on the outer side face of the steel core; ventilating holes penetrating through the steel core are formed on two end faces of the steel core; the conveyer belt is arranged in a bottom position in the cutting room; a feed inlet and the exhaust hood are formed above the cutting room; the air blower which blows towards the rubber roller and the traction roller are arranged on one side in the cutting room; a discharge opening is formed below the right side of the cutting room. The plastic dicing device with good radiation disclosed by the invention can be used for effectively avoiding roller explosion induced by over-high temperature in the using and production processes of the rubber roller and effectively and immediately discharging heat and water vapor in the cutting room so as to avoid a series of equipment failure.

Description

technical field [0001] The invention relates to the technical field of plastic product production, in particular to a plastic pelletizing device with good heat dissipation. Background technique [0002] In the production process of plastic products, the plastic strips extruded by the extruder need to be cooled in a water tank and then cut into granular particles. Most of the current granulation devices use the double-drum mechanism to pull the material, and then cut it through the rotating cutter head. However, due to the long-term conveying of the material strip, the friction between the material strip and the double-drum for a long time will cause a large amount of friction on the rubber roller. In severe cases, it will cause the roll to burst; and the existing granulation devices are all closed cutting chambers, leaving only one inlet and outlet, and when engineering plastics enter the granulator through water cooling, there is still a certain temperature, which will last...

Problems solved by technology

Most of the current pelletizing devices use the double-drum mechanism to pull the material, and then cut it through the rotating cutter head. However, due to the long-term conveying of the material strip, the friction between the material strip and the double-drum for a long time will cause a large amount of friction on the rubber roller. In severe cases, it will cause the roller to explode; and the existing granulation devices are all closed cutting chambers, leaving only one inlet and one outlet, and when engineering plastics enter the granulator through water cooling, there is still a certain temperature, which will last for a long time. After work, the heat is not dissipated in time, resulting in high temperature and water vapor in the cutting room, which will cause a series of equipment failures, such as premature aging of rubber rollers, shortening service life, water vapor causing rust inside the equipment, cutting The rust layer will adhere to the raw material, resulting in insufficient cleanliness of the finished material and affecting the quality of the finished product
