Description

Technical Field

[0001] The invention relates to the technical field of XPE foam sheet molding and processing, in particular to an XPE foam sheet thinning and molding device. Background Art

[0002] XPE is chemically cross-linked polyethylene foam material, which is made by continuous foaming of low-density polyethylene resin, cross-linking agent and foaming agent at high temperature. Compared with EPE, it has higher tensile strength and finer pores. XPE foam sheet is hot-pressed by molding equipment.

[0003] When existing equipment conveys XPE foam sheets, it realizes conveyance through the contact friction between the conveying roller and the XPE foam sheets, and the XPE foam sheets are stored in rolls. Therefore, during transportation, the XPE foam sheets are prone to bending, undulations and fluctuations. At the same time, in the early stage of transportation, it is necessary to manually pass the ends of the XPE foam sheets through the pressing rollers and the equipment in turn, and the initial feeding work needs to be completed through manual operation; when working through the hot pressing mold, during the gap in the feeding of the XPE foam sheets, the hot pressing mold emits a large amount of heat that cannot be utilized, and when processing in cold weather, the surface temperature of the XPE foam sheets is low due to the external environment, and then during the hot pressing molding process, the temperature of the XPE foam sheets rises slowly, resulting in low processing efficiency. Summary of the invention

[0004] The problem solved by the present invention is to provide an XPE foam sheet thinning and molding equipment, which solves the technical problem that the existing equipment realizes the conveying of XPE foam sheets by the contact friction between the conveying roller and the XPE foam sheets when conveying the XPE foam sheets, and the XPE foam sheets are stored in rolls, so the XPE foam sheets are prone to bending, undulation and fluctuation during conveying, and at the same time, in the early stage of conveying, the ends of the XPE foam sheets need to be manually passed through the pressing rollers and the equipment in sequence, and the initial feeding work needs to be completed by manual operation; when working through the hot pressing mold, during the XPE foam sheet feeding gap, the hot pressing mold emits a large amount of heat that cannot be used, and in cold weather processing, the surface temperature of the XPE foam sheets is low due to the external environment, and then during the hot pressing molding process, the temperature of the XPE foam sheets rises slowly, resulting in low processing efficiency.

Then, when the XPE foam sheet is transported by the preheating roller, the XPE foam sheet is preheated, the efficiency of subsequent hot pressing and thinning is improved, the heat of the hot pressing upper mold and the hot pressing lower mold is recovered and reused, resources are saved, heat loss is reduced, and production costs are reduced.
