Abstract

The invention discloses a chemically cross-linked polyethylene foam device which comprises a feed apparatus, a horizontal foaming apparatus, a front-back press polish apparatus and a roll apparatus sequentially arranged, wherein the horizontal foaming apparatus is sequentially provides with a horizontal foaming furnace with three heating areas, three cyclic heating mechanisms arranged above the horizontal foaming furnace and correspondingly communicated with heating areas, the cyclic heating mechanisms comprises a box body fixed on and communicated with the horizontal foaming furnace, a gas combustion machine fixed on the box body, a heat exchange system located in the box body and connected with the gas combustion machine, and a hot air circulation fan used for transferring the heat in the box body to the foaming areas; the heat exchange system comprises a combustion cylinder with one opened end and one closed end, the opened end of the combustion cylinder is communicated with a flame port of the gas combustion machine, and sidewalls of the combustion cylinder is provided with a plurality of output holes in intervals. The device is advantageous by preventing entry of the flames into impellers to deform and damage the impellers, and improving service life of the hot air circulation fan.

Description

technical field [0001] The invention relates to a polyethylene foaming device, in particular to a chemically cross-linked polyethylene foaming device. Background technique [0002] The existing chemically cross-linked polyethylene foaming equipment includes a feeding device, a horizontal foaming device, a front and back calendering device, and a winding device arranged in sequence. In the foaming device, the polyethylene master sheet is chemically cross-linked and foamed in the foaming device to obtain a semi-finished product of chemically cross-linked polyethylene foam sheet, and then the chemically cross-linked polyethylene is foamed by the front and back calendering devices. The semi-finished foam sheet is calendered to obtain a finished chemically cross-linked polyethylene foam sheet, and finally the finished chemically cross-linked polyethylene foam sheet is wound up by a winding device. [0003] The horizontal foaming device in the chemically cross-linked polyethylene...
