Polyurethane plastic film two-way stretching processing system

Abstract

The invention relates to a polyurethane plastic film two-way stretching processing system. The polyurethane plastic film two-way stretching processing system comprises a feeding roller, a placing platform, a first stretching mechanism, a second stretching mechanism, a discharging roller and a driving mechanism, wherein the first stretching mechanism and the second stretching mechanism are respectively mounted on two sides of the placing platform, and are fixed to the placing platform through bolts; the first stretching mechanism and the second stretching mechanism are two components of which the structures are completely the same; the driving mechanism is arranged on the top of the first stretching mechanism; the feeding roller is mounted at one end of the placing platform; the dischargingroller is mounted at the other end of the placing platform; a first protective shell and a second protective shell are respectively and correspondingly mounted on the upper end surface of the secondstretching mechanism and the upper end surface of the first stretching mechanism through bolts; and a driving motor is mounted on the top of the second protective shell. By the polyurethane plastic film two-way stretching processing system, continuous two-way stretching work on a coiled thick film can be carried out, the stretching efficiency is high, and the stretching effect is good.

Description

technical field [0001] The invention relates to the technical field of polyurethane plastic film processing, in particular to a polyurethane plastic film bidirectional stretch processing system. Background technique [0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging, and as a coating layer. Polyurethane plastic film is one of many plastic films. There are many ways to form and process polyurethane plastic films, and biaxially stretched films have become the focus of attention. The biaxially stretched film is to heat and melt the high-plant resin through an extruder to extrude a thick sheet, and then stretch the thick sheet by a certain multiple under the action of an external force to make it an ideal plastic film. [0003] However, the polyurethane plastic film biaxial stretching processing system in the current market has the following problems in the operation process: a. when the tr...

Problems solved by technology

[0003] However, the polyurethane plastic film biaxial stretching processing system in the current market has the following problems in the operation process: a. when the traditional polyurethane plastic film biaxial stretching processing system stretches the extruded thick sheet film, the stretching process Independent setting is adopted, that is, the rolled thick film needs to be cut separately and then stretched independently, that is, the continuous processing of the rolled thick film cannot be effectively performed, resulting in low stretching efficiency of the processing system; b. due to polyurethane When the plastic film biaxial stretching processing system stretches the thick film, the contact area between the clamping device and the film is small, that is, the clamping device cannot effectively cover the surface of the film completely, resulting in When the thick film is stretched, the force on both sides of the film is uneven, resulting in insufficient stretching of the local area on the surface of the thick film, and the stretching effect of the film is poor.
