PP decorative film casting machine

Abstract

The invention relates to the technical field of casting machines, in particular to a PP decorative film casting machine. The PP decorative film casting machine comprises a feeding platform frame, a drying mixer, a screw feeder, a variable-frequency drive motor, an extruder base, a rim charge recovering and forced feeding device, a PP raw material plasticizing screw charging barrel, an oil pressurefilter screen replacing device, a hanger type special die head, a 90-degree elbow device, a complete machine console, a film forming table device, an adjustable auxiliary cooling roller, a forming steel roller, a forming rubber roller, a secondary cooling traction device, a water chilling unit and a water die temperature unit, the feeding platform frame is fixedly installed on the right side of the drying mixer, and the screw feeder is fixedly installed on the left side of the drying mixer. According to the PP decorative film casting machine, the purposes of reducing energy consumption, improving the automatic control process, reducing the production cost and improving the product quality are achieved, the automatic feeding process of raw materials can be more stable, the transparency, gloss and thickness uniformity of the film are improved, and the effect of obviously reducing the labor cost is achieved.

Description

technical field [0001] The invention relates to the technical field of casting machines, in particular to a PP decorative film casting machine. Background technique [0002] PP decorative film is a kind of decorative film applied on the surface of paint-free furniture made of polypropylene. Its visual effect is comparable to that of wood veneer. It can be coated with back glue. The treatment of back glue can make the film and various workpieces play a more sticky role, making the product more durable; the biggest advantage of the environmentally friendly PP film is that it can be degraded when recycled, and only water and carbon dioxide are released when burned. , does not produce any toxic gas, which brings good news to the protection of the environment.

Due to the competition of product prices in the market, this model is still equipped ...

AI Technical Summary

Problems solved by technology

[0003] In the use of tape casting machine, its own manufacturing process requirements are complicated, and assembly precision is high. Due to the competition of product prices in the market, this model is still equipped with traditional three-phase different motors for transmission, and energy saving is not very prominent. , waste energy to a great extent, and at the same time, the efficiency of the automatic control process is low, and the production of the machine still needs to be equipped with two people to cooperate in the operation of the machine. The cooling effect of the water channel designed by the forming roller and the forming silicone rubber roller due to the rigidity requirements is poor, and In the past, the method of vacuum suction feeding will change the proportion of raw materials, which will affect the performance of the product, such as flatness and shrinkage.
