Description

Technical Field

[0001] This utility model belongs to the technical field of sheet production equipment, and particularly relates to a PET sheet production equipment. Background Technology

[0002] PET sheet is a type of plastic sheet made of polyethylene terephthalate. It has good transparency, gloss, mechanical properties and chemical stability, and is widely used in packaging, electronics, medical and other fields. PET sheet production equipment is a series of equipment used to produce PET sheets, mainly including mixers, extruders, dies, three-roll calenders, cooling devices and cutting machines.

[0003] Existing PET sheet cooling devices generally adopt a single-sided cooling method, which results in uneven heating on both sides of the PET sheet during cooling. Due to the difference in heat transfer, uneven stress is generated inside the sheet, which in turn makes the PET sheet prone to quality problems such as deformation and warping, affecting the product qualification rate and performance. Moreover, the single-sided cooling method is inefficient and has a slow cooling rate, which also limits the improvement of production efficiency. Therefore, it is necessary to improve this method. To this end, a PET sheet production equipment is proposed. Utility Model Content

[0010] As a further description of the above scheme: the temperature sensors arranged in the box and on the cooling table respectively can monitor the temperature in the box and on the cooling table respectively.
