Manufacturing method of PVC pellet production cutting device

The utility model relates to the field of pvc pellet production, in particular to a pvc pellet production cutting device.

Background technique:

2. Polyvinyl chloride, abbreviated as pvc in English, is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. Application: PVC pellets are commonly known as plastic rice, which is an intermediate product of PVC processing, which is processed into finished products after hot melting of PVC pellets.

3. At present, the patent number "201821570540.3" and the patent number "201921696869.9" respectively disclose a pvc pellet production and cutting device, but the device is all cut in the molten pvc, which is easy to cause the molten pvc to cut Full or molten pvc adheres to the blade; and the patent number "202020413349.9" discloses a pvc pellet cutting device, which first cools the molten pvc into a solid pvc through a water tank, and then The solid pvc is cut, which effectively prevents the molten pvc from sticking to the blade.

4. However, in the process of realizing the application, the above-mentioned devices still have the following defects and deficiencies:

5. When the pvc cooled into a solid strip by the water tank is transported to the rotating blade and the fixed blade for cutting through the strip conveyor, the rotating blade and the fixed blade are located outside the end of the conveyor belt of the strip conveyor, so the solid strip The PVC is cut in a suspended state, which will easily cause insufficient cutting, that is, it is easy to be incompletely cut into granular PVC.
