Sealing machine for food processing

Abstract

The invention relates to the technical field of food processing, and discloses a sealing machine for food processing. The sealing machine comprises four driving wheels, wherein the exteriors of every two driving wheels are movably sleeved with an annular thin belt, heating blocks are movably mounted at one ends of the inner sides of the annular thin belts, and heat transfer sheets are movably mounted at the top ends of the heating blocks. According to the sealing machine, gas in gas bags expands when heated, then the heating blocks extrude the annular thin belts downwards, then the contact area between packaging bag films is increased, heat energy conduction is effectively promoted, and the film melting degree is better; the gas bags are subjected to heat conduction and cooling in time through heat conduction sheets, the influence of excessive expansion of the gas bags on sealing is avoided, heat dissipation of the heating blocks can also be promoted, and mechanical damage caused by overheating of heating parts is avoided; and wind energy used by cooling mechanisms is conducted and conveyed again through air conveying belts, the heat dissipation effect of parts in a heating mechanism in the sealing machine is enhanced, and the stability of equipment and the sealing quality are effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a sealing machine for food processing. Background technique [0002] The sealing machine is a kind of processing equipment that seals the opening end of the packaging bag through automatic equipment after the food packaging bag is filled with food. Through a pair of relatively rotating shaft wheels, the annular thin belt is driven to clamp and transport the food packaging bag, and then through the heating block, the film at the opening end of the packaging bag is heated to make it bond, and then it is embossed with an embossing roller. Rolling, and then through the cooling mechanism, the seal is cooled and solidified. This heat-sealing method is suitable for various composite film materials, and the sealing speed is high, so it is widely used. [0003] In the existing components, because the structure of the heating block is fixed, its position is controlled by the adjus...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the use of the existing sealing machine proposed in the background technology, the present invention provides a sealing machine for food processing, which is equipped with a heating block that can actively press down when heating the film to increase the pressure and promote the sealing of the film. The advantages of heat conduction between them, avoiding incomplete melting of the film, and improving the qualified rate of sealing, solve the technical problems raised in the above-mentioned background technology
