Multi-film heat seal cutting machine

Abstract

The invention discloses a multi-film heat seal cutting machine. The multi-film heat seal cutting machine comprises a support, a base plate, a slide rail, an electrothermal mechanism and a transmission device. A cutting disk and a metal anvil are arranged on the electrothermal mechanism, the openings for respectively passing each metal anvil through are arranged on the cutting disk, a vertical and downward cutting knife is arranged on edge of each opening; a downwardly and deeply-recessed knife groove corresponding to the cutting knife and a heat seal bench corresponding to the metal anvil are arranged on a base plate, each metal anvil is arranged on a substrate, and an elastic component capable of keeping a maximum limit distance between the substrate and the electrothermal mechanism is arranged between the substrate and the electrothermal mechanism. The multi-film heat seal cutting machine realizes batch thermocompression and cutting for a filter composite membrane, through a recess design of the heat seal bench and a spacing plate apparatus, multiple groups of multilayer films are completely overlapped, the overlapping precision is high, sidesway is not generated, production precision for automatic heat sealing is increased; automatic high frequency hot pressing is carried out, fusion is generated between the membrane and the membrane, corrugation is not carried out, heat sealing is carried out while cutting is carried out, so that production efficiency is greatly increased.

Description

technical field [0001] The invention relates to the field of medical and sanitary products production equipment, in particular to a multi-film heat-sealing cutting machine. Background technique [0002] Due to the excellent hydrophilicity of the inorganic membrane, it is easy to deform and diverge when treated with water or treatment liquid. Therefore, before the dipping treatment, it must be covered with an organic membrane up and down, and the periphery is heat sealed. The specific operation is to flatten the three layers of film together, place the organic film on the top and bottom, and the inorganic film in the middle, and manually heat and press with an electric iron to make the upper and lower organic films coated on the inorganic film thermally bonded together. Generally between 150°C and 180°C. Inorganic film heat sealing adopts edge heat sealing, which is required to be resistant to water, alcohol, etc. After being treated with polymer organic solution and dried, ...

AI Technical Summary

Problems solved by technology

At present, there is no device for automatic heat-sealing of inorganic films. Using traditional methods to produce heat-sealing inorganic film products requires high labor costs, long-term use of electric irons, high power consumption, and insufficient stability of manual operation, resulting in uneven composite films. , easy to wrinkle, resulting in high scrap rate

[0003] After the multi-film is heat-sealed, it is necessary to cut the excess film on the outer periphery of the heat-sealing surface. The existing cutting is done manually. If the film has a special shape, it will greatly increase the labor cost.

However, the traditional cutting equipment cannot meet the precision requirements, and the product yield is affected
