Description

Technical Field

[0002] PVC compound, also known as polyvinyl chloride compound, is a multi-component plastic material. PVC compound is made of polyvinyl chloride resin powder as the base material, and is added with various additives such as plasticizers, stabilizers, lubricants, etc. to meet different processing and performance requirements. When processing and granulating PVC compound, the plasticized compound needs to be extruded into a continuous strip through the die of an extruder, and then the extruded strip is cooled by a cooling device to reduce its temperature and solidify it. Finally, the cooled strip is cut into pellets of a certain length and size by a pelletizer, and the pelletizing of the PVC compound is completed. When cooling the extruded strip, a cooling water tank is often used. When the water in the cooling water tank cools the strip, the water temperature will be uneven due to the heat transfer of the strip. At this time, a temperature gradient will appear in the cooling water, that is, the temperature of the water close to the strip will be higher than the temperature of the water far away from the strip, which will make the cooling efficiency of the strip lower. Therefore, a granulating device for PVC compound processing is needed to solve the above problems. Utility Model Content

When in use, a pelletizer needs to be set behind the cooling water tank 3, and cooling water is put into the cooling water tank 3. During use, the extruder 1 extrude the plasticized rubber material into continuous The extruded rubber strip is then cooled through the cooling water tank 3 to reduce its temperature and solidify it. Finally, the cooled rubber strip is cut into particles of a certain length and size through a pelletizer. At this time, the granulation of the PVC rubber material is completed. When the rubber strip passes through the cooling water in the cooling water tank 3, the drive motor 5 can be started. At this time, the drive motor 5 will drive the reciprocating screw 8 on the rotating spoiler device 7 and the reciprocating spoiler device 6 to rotate in the cooling water. As the reciprocating screw 8 rotates, the reciprocating spoiler 11 will move back and forth in the cooling water tank 3. Finally, by setting the spoiler component 4 and the drive motor 5, the water in the cooling water tank 3 can be disturbed and mixed, thereby enhancing The convective heat exchange of the cooling water in the cooling water trough 3 makes the temperature distribution of the cooling water in the cooling water trough 3 more uniform, reduces the temperature gradient, and thus can increase the rate of heat transfer from the extruded rubber strip to the cooling water, and ultimately can improve the cooling efficiency of the extruded rubber strip.
