Cooling box at outlet of adhesive tape extruder

Abstract

The invention discloses a rubber strip extruder outlet cooling box which comprises a box body, the inner wall of the box body is of a hollow structure, a heat insulation plate is installed in the inner wall of the box body, a supporting plate is installed in the box body, a main cooling structure is installed in the box body, a plurality of rubber strip pipes are arranged on the upper side of the supporting plate and penetrate through the box body, and a drying structure is inserted in the right side of the box body. According to the outlet cooling box of the adhesive tape extruder, an adhesive tape is output outwards through the adhesive tape pipe and is cooled when passing through the interior of the box body, under the general condition, the main cooling structure is used for lowering the interior of the box body, the main cooling structure is used for cooling the interior of the box body, and the auxiliary cooling structure is connected with the main cooling structure. The temperature of an inner cavity of the upper portion of the box body is reduced through the temperature of the upper portion divided by the supporting plate, rubber strips passing through rubber strip pipes can be cooled to a certain degree, different rubber strip pipes can be further cooled by starting the auxiliary cooling structure, and the cooling degree is controlled.

Description

technical field [0001] The invention relates to the technical field of PE product manufacturing, in particular to an outlet cooling box of a rubber strip extruder. Background technique [0002] Polyethylene (PE) is one of the five major synthetic resins, and it is the variety with the largest production capacity and the largest import volume among synthetic resins in my country. Polyethylene is mainly divided into three categories: linear low density polyethylene (LLDPE), low density polyethylene (LDPE) and high density polyethylene (HDPE). [0003] In the production process of PE products, a rubber strip extruder is essential. After some rubber strips are extruded, a cooling device needs to be set at the outlet of the rubber strip to facilitate the faster export of the rubber strip. The existing cooling device The cooling capacity cannot be controlled, so that the performance is poor for different products, and there is a large amount of water vapor in the box after long-t...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a cooling box at the outlet of the strip extruder, which solves the problem that the existing cooling capacity cannot be controlled, and a large amount of water vapor in the box affects the cooling work.
