Energy-saving and environment-friendly plastic cold pelletizing system

Abstract

The invention relates to the technical field of plastic processing, and in particular relates to an energy-saving and environment-friendly plastic cold pelletizing system. The energy-saving and environment-friendly plastic cold pelletizing system comprises a rack, as well as a water cooling mechanism, a screening mechanism and a pelletizing mechanism which are sequentially arranged on the rack inthe first direction, wherein the water cooling mechanism comprises a water cooling tank, a separation roll, a first guide roll and a draining roll, and a water inlet pipe and a water outlet pipe whichcommunicate with an inner cavity of the water cooling tank are respectively arranged on the side wall of the water cooling tank; the screening mechanism comprises a screening plate, first pressing rolls, second pressing rolls, second guide rolls, lifting bearings, cams, servo motors, a gear chain assembly, third pressing rolls and fourth pressing rolls, flow guide holes are formed in the first pressing rolls and the second pressing rolls along the axes, and the water outlet pipe communicates with the first pressing rolls and the second pressing rolls through a universal joint; and the pelletizing mechanism comprises a hydraulic cylinder and a cutting die. According to the energy-saving and environment-friendly plastic cold pelletizing system, the cooling and drying effects of the plasticpelletizing system are improved, and the energy-saving and environment-protecting development concept is met.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to an energy-saving and environment-friendly plastic cold pelletizing system. Background technique [0002] With the progress of society, plastic products are gradually replacing wooden and metal products. Plastic products are mainly made of plastic particles through injection molding, blow molding and other processes. At present, in the process of preparing plastic granules, the raw materials are generally put into the melt extruder, and the plastic strips continuously extruded from the extrusion die enter the cooling tank filled with water for cooling, and finally enter the granulator to cut into granules. . However, since the plastic strips entering the granulator contain too much moisture, after directly entering the granulator, the excess moisture will seriously affect the use of the granulator and shorten the life of the granulator. The advanced pelletizing syste...

Problems solved by technology

However, since the plastic strips entering the granulator contain too much moisture, after directly entering the granulator, the excess moisture will seriously affect the use of the granulator and shorten the life of the granulator. The pelletizing system consumes a lot of energy during drying and cooling operations, and it does not conform to the production concept of energy saving and environmental protection
