Electronic irradiating crosslinked polyethylene foaming machine

Abstract

The invention relates to an electronic irradiating crosslinked polyethylene foaming machine, which comprises a horizontal conveying device, a horizontal preheating device, a vertical foaming device, an unfolding device, a positive and negative calendaring device and a coiling device which are successively arranged. The electronic irradiating crosslinked polyethylene foaming machine is characterized in that the vertical foaming device comprises a vertical foaming furnace; the vertical foaming furnace is provided with a transition area, a pre-foaming area and a foaming area; a plurality of first electric heating tubes, a plurality of second electric heating tubes, a plurality of third electric heating tubes, a plurality of first hot air circulating fans, a plurality of second hot air circulating fans and a plurality of third hot air circulating fans are arranged in the vertical foaming furnace; the first electric heating tubes and the first hot air circulating fans are located in the transition area; the second electric heating tubes and the second hot air circulating fans are located in the pre-foaming area; and the third electric heating tubes and the third hot air circulating fans are located in the foaming area. After the electronic irradiating crosslinked polyethylene foaming machine provided by the invention is adopted, the production efficiency and yield of the polyethylene foamed products are greatly increased.

Description

Technical field [0001] The invention relates to a polyethylene foaming equipment, in particular to an electronic radiation cross-linked polyethylene foaming equipment. Background technique [0002] Polyethylene foam materials have excellent physical, chemical and mechanical properties and are widely used in automotive, sports, construction engineering, electronics, packaging, transportation and other fields. Electronically irradiated cross-linked polyethylene foamed products (IXPE for short) have the advantages of reducing environmental pollution, easy process control, improving product quality, improving production efficiency, and reducing mass production costs. [0003] The electronic radiation cross-linked polyethylene foaming equipment generally includes a horizontal conveying device, a horizontal preheating device, a vertical foaming device, an unfolding device, a front and back calendering device, and a winding device arranged in sequence. The working process is: first horizo...

AI Technical Summary

Problems solved by technology

Since 2006, some domestic enterprises have begun to design and manufacture the equipment by themselves, but the results are not ideal, and the failure rate of the manufactured equipment is high and the production efficiency is low.

The existing vertical foaming device for cross-linked polyethylene foamed by electron irradiation generally adopts the direct radiation heating method of the heating tube. , resulting in unqualified products, low production efficiency and yield
