High-molecular coiled material extrusion composite device

Abstract

The invention relates to a high-molecular coiled material production device, and concretely provides a high-molecular coiled material extrusion composite device. The high-molecular coiled material extrusion composite device is composed of composite rollers, high-molecular extrusion dies, regulating screws and a hot air blowing and melting machine. The two removable high-molecular extrusion dies are respectively arranged at two sides of the device. The high-molecular extrusion dies have a tapered structure. Adjusting screws are arranged at both the upper part and the lower part of each high-molecular extrusion die. At least three composite rollers are arranged at the right side of the device from up to down. At least two composite rollers are arranged at the left side of the device from up to down. A hot air blowing and melting machine is arranged at the upper part of the left side of the device and above the composite rollers. A support bar is arranged on the hot air blowing and melting machine. A wind-up roller is arranged under the left high-molecular extrusion dies. Output rollers are arranged above right composite rollers. The output rollers are connected with a grid cloth roller.

Description

technical field [0001] The invention relates to high polymer roll production equipment, in particular to a high polymer coil extrusion composite device. Background technique [0002] The non-rolling lamination machine is a commonly used composite material production equipment, mainly used for the two-layer or multi-layer lamination production process of various types of cloth, leather, film, paper, sponge, etc., especially for polymer waterproof membranes. , the existing extrusion compounding device mainly has the following two types, see the attached figure 1 and attached figure 2 , with figure 1 The extrusion composite device in the product has firm compounding and high peel strength, but it is also inconvenient to adjust the thickness of the product. The lower mold is almost impossible to adjust, and it is easy to burn the arm. The pass rate is very low.

[0002] The non-rolling lamination machine is a commonly used composite material production equipment, mainly used for the two-layer or multi-layer lamination production process of various types of cloth, leather, film, paper, sponge, etc., especially for polymer waterproof membranes. , the existing extrusion compounding device mainly has the following two types, see the attached figure 1 and attached figure 2 , with figure 1 The extrusion composite device in the product has firm compounding and high peel strength, but it is also inconvenient to adjust the thickness of the product. The lower mold is almost impossible to adjust, and it is easy to burn the arm. The pass rate is very low. When the mold is disassembled and cleaned, it is very inconvenient to disassemble the mold. , the two molds must use hoisting equipment to lift the molds away from the production line, and disassemble them squarely on a special bracket. It will take 6-8 hours to resume production after the two molds are cleaned, and there are hidden dangers to personal safety and equipment. Due to the mold The adjustment is extremely inconvenient, and even impossible to adjust. The required thickness of the produced product cannot be guaranteed, so the pass rate of the product is very low

[0003] Existing extrusion compounding equipment sees attached figure 2 , the thickness adjustment required by the product is better than the attached figure 1 The structure of the device is not ideal, and there is a set of disassembled molds with attached figure 1 The devices are the same, and one can be disassembled and cleaned online. Due to the problems in the equipment structure, the installation position of the hot air blowing melting machine cannot be close to the compound point of the two films, and it is difficult for the hot air blowing melting machine to heat the first layer of film by radiation. The surface is plasticized at the moment of compounding, and the surface of the film is deformed when the temperature is too high, so the compounding of the product is not firm enough, and the peel strength is unqualified
