Thickness setting device of continuous foaming material

Abstract

The invention belongs to the technical field of production equipment of foaming materials, and particularly discloses a thickness setting device of a continuous foaming material. The thickness settingdevice comprises a foaming cavity and a thickness locking part, wherein the two ends of the foaming cavity are provided with a feeding port and a discharging port respectively, several heating elements are arranged on the inner wall of the foaming cavity in the conveying direction of the foaming material, the thickness locking part is arranged outside the discharging port, and comprises a pressure roll and a steering roll which are oppositely arranged and communicate with a cooling medium pipeline, the surface of at least one of the pressure roll and the steering roll is provided with a cooling structure, at least one of the pressure roll and the steering roll is a driving roll driven by power equipment to rotate, and the foaming material is conveyed out in a way of fitting the surface ofthe steering roll after passing by a pressing area between the pressure roll and the steering roll. By means of the thickness setting device, precise and quick thickness setting of the foaming material can be achieved, dimensional deviation of the finished product is effectively lowered, and the quality of the finished product is improved.

Description

technical field [0001] The invention belongs to the technical field of foaming material production equipment, and in particular relates to a thickness setting device for continuous foaming materials. Background technique [0002] Sheet foaming refers to the process of heating a strip-shaped polymer material in a foaming furnace, and the foaming agent decomposes at high temperature to generate gas, fills the inside of the polymer material, and produces a foaming material with closed pores. In production, after the foaming is completed, the foaming material needs to be cooled and shaped by a cooling device, and then rolled directly or after some post-processing procedures (such as edge trimming, embossing, cutting, etc.) to obtain the finished product. In the above-mentioned process, the cooling and shaping process is particularly important, which directly determines the quality of the finished product. Most of the shaping devices of the existing foaming material production li...

In the above-mentioned process, the cooling and shaping process is particularly important, which directly determines the quality of the finished product. Most of the shaping devices of the existing foaming material production line are cooling roller groups (such as CN105599210B, CN209111359U) located outside the foaming furnace, and have the following defects: one is The cooling speed is slow, although it can be improved by increasing the number of cooling roller groups or increasing the pressure on the rollers, but the former consumes a lot of energy and the latter is easy to over-extrude or even break the sheet; more importantly, the
