Embodiment Construction

[0024] Combine the following figure 1 , to describe preferred embodiments of the present invention in detail.

[0025] Such as figure 1 as shown, figure 1 It is a schematic diagram of the overall structure of the present invention. An automatic temperature-controlled cooling device for plastic granulation, comprising a water tank 5 engraved with a safety water level line 4 , a water inlet component 6 , a safe water level outlet component 7 , a temperature control component 8 and a drainage component 9 .

[0026] The inside of the water tank 5 is provided with a pressure roller 51 fixedly connected to the water tank 5 by welding, and the safety water level 4 is 5 to 20 cm higher than the position of the pressure roller 51 in the water tank 5, so as to ensure that the material strip 2 is immersed in the water tank during normal production. 5 in the cooling water. The pressure roller 51 arranged in the water tank 5 immerses the molten plastic strip 2 extruded by the extruder ...

Abstract

The invention relates to an automatic temperature control cooling device for plastic granulation. The device comprises a trough engraved with a safety water line, an inflow assembly, an outflow assembly at the safety water line and a temperature control assembly. Wherein, the inflow assembly includes an inflow pipe communicated with the trough and an electromagnetic valve disposed on the inflow pipe. The outflow assembly at the safety water line includes an outflow pipe located at the safety water line and communicated with the inside of the trough by an outlet at the safety water line. And the outlet at the safety water line is abreast with the safety water line. The temperature control assembly contains a temperature control module outside the trough, an input module and a test module fixed in the trough and below the safety water line, with the temperature control module, the input module, the test module and the electromagnetic valve connected by circuits. In the plastic granulation process of the invention, plastic particles with a shrinkage hole in the center can be decreased to meet the requirements of injection molding. Besides, the amount of cooling water in the trough can be reduced, thus saving energy, protecting the environment and indirectly improving economic benefits.

Description

technical field [0001] The invention relates to an automatic temperature-control cooling device for plastic granulation, in particular to an automatic temperature-control cooling device for cold-cut granulation of modified plastic granulation. Background technique [0002] In the prior art, the granulation of modified plastics by cold cutting requires water as a medium to cool the molten plastic strips. The water temperature of the cooling water tank will affect the appearance of the plastic pellets. If the water temperature is too high, the heat exchange efficiency of the molten plastic strips in the plastic granulation cooling water tank is low, the plastic strips are not easy to cool, and the granulation is easy to produce a large number of joint granules; Shrinkage voids, particles with hollow shrinkage holes are prone to product defects during injection molding, and waste water resources. Contents of the invention [0003] The purpose of the present invention is to ...
