Novel drying cylinder for producing PVC rolling film

Abstract

The invention provides a novel drying cylinder for producing a PVC rolling film. The novel drying cylinder comprises a cylinder body, the cylinder body is arranged on a supporting frame, a storage hopper, a material adjusting mechanism and a discharging mechanism are sequentially arranged in the cylinder body from top to bottom, a filter screen is arranged at a storage outlet in the lower end of the storage hopper, the material adjusting mechanism comprises a movable plate and an air cylinder, the discharging mechanism comprises a material distributing barrel and a disc, the disc is arranged below the movable plate, the edge of the disc is fixed to the inner wall of the cylinder body, the material distributing barrel can rotate along the disc, a plurality of material distributing cavitiesare formed in the outer wall of the material distributing barrel, drying bodies are arranged on the left side and the right side of the interior of the cylinder body and are arranged close to the material distributing barrel, and each drying body comprises a drying fan and an air outlet pipe. The novel drying cylinder has the beneficial effects that the material adjusting mechanism and the discharging mechanism are arranged, so that the uniform drying effect on raw materials can be rapidly realized, the processing quality of the raw materials can be improved, and the working efficiency can beimproved.

Description

technical field [0001] The invention belongs to the technical field of producing PVC calendering films, in particular to a novel drying cylinder for producing PVC calendering films. Background technique [0002] PVC calendered film is made by calendering process. Calendering is to pass the heated polyvinyl chloride plastic through the gap between one or more pairs of horizontal rollers rotating in opposite directions, so that the material is subjected to extrusion and extension, and becomes a film with a certain thickness. Process for thin products with smooth width and surface. During the processing of raw materials, raw materials need to be dried before they can be put into subsequent operations. At present, the drying of raw materials is mainly carried out by placing raw materials in industrial drying boxes, but there are problems with the drying of raw materials. Uniformity, the raw materials cannot be dried quickly and thoroughly, which directly affects the subsequent ...
