Description

Technical Field

[0002] XPE is chemically cross-linked polyethylene foam material, which is made of low-density polyethylene resin, cross-linking agent and foaming agent through high-temperature continuous foaming. It has stable chemical properties, is not easy to decompose, has no odor, and has good elasticity. Therefore, XPE material is widely used in various fields. The processing of XPE sheet needs to go through the processes of foaming, molding, cooling, deviation correction, edge trimming, traction, static electricity removal, and winding in sequence.

[0003] Chinese patent CN221756629U discloses an environmentally friendly XPE foam material cooling device, including a main body, a control mechanism and an auxiliary mechanism, wherein the control mechanism is located at the front end of the main body, and the auxiliary mechanism is located at the lower end of the main body, and the main body includes a fixed base, a cooling box and a movable door. The device places the foam material on a foam material placement plate, and then starts a refrigerator, which generates cold air, which is guided to the air guide plate through a guide pipe, and the air guide plate is used to guide the cold air to be evenly distributed on the entire cross section of the cooling box, thereby ensuring uniform contact between the foam material and the cold air, and thus the foam material can be quickly cooled.

The second driving motor drives the driving conveying roller to rotate. With the cooperation of the second transmission sprocket, the third transmission sprocket and the second transmission chain, the second cooling transmission roller follows the rotation, so that after the XPE sheet is initially cooled on the inner side of the first feed rack, it enters the inner side of the second feed rack, and the lifting device and the water pump are controlled to start working, driving the lifting support mounting plate to lift, so that the first cooling transmission roller contacts the top of the XPE sheet.
