A forming and sealing device for food packaging machine

Abstract

The invention discloses a forming and sealing device used for a hollow packaging machine of food. The forming and sealing device comprises a rack, a cutter sealing angle component and a bag forming component, wherein the cutter sealing angle component comprises a bracket, a first expansion link, a second expansion link, an upper fixing plate, a lower fixing plate, an upper heat sealing seat, a lower heat sealing seat, a first angle plate and a second angle plate, wherein the upper fixing plate and the lower fixing plate penetrate through the first expansion link and the second expansion link; the upper heat sealing seat is fixedly arranged on the upper fixing plate; the lower heat sealing seat is fixedly arranged on the lower fixing plate; the first angle plate and the second angle plate are positioned between the upper heat sealing seat and the lower heat sealing seat; the upper heat sealing seat and the lower heat sealing seat are driven by an air cylinder assembly installed on the bottom of the bracket; the first angle plate is driven by a first angle air cylinder sheathing the first expansion link; the second angle plate is driven by a second angle air cylinder sheathing the second expansion link; the first angle plate and the second angle plate are symmetrically arranged. According to the forming and sealing device used for the hollow packaging machine, the cutter sealing angle component can be used for carrying out continuous end surface angle and sealing on a vertical sealing square bag, so that the forming and sealing efficiency of whole package is improved so as to improve the packaging efficiency of a finished product.

Description

technical field [0001] The invention relates to the technical field of food packaging, in particular to a forming and sealing device for a food packaging machine. Background technique [0002] With the continuous progress and development of technology, many of the food circulating on the market are packaged into bags by packaging machines, and the food packaged into bags has many advantages. It is mainly reflected in three aspects: packaged food is convenient for circulation; some packaging is a container for food circulation. Such as bottled wine, beverages, canned food, field-packed milk powder, etc., these packaging bottles, cans and bags are not only packaging containers. It is also a moving tool for food circulation and sales. It brings great convenience to food circulation. Protecting food and prolonging the shelf life of food; protecting the appearance quality of food produces certain economic benefits. In the whole circulation process, food has to go through handl...

Problems solved by technology

[0004] In the food packaging machine disclosed in this patent document, when the food is packaged, the lapel type hollow former first folds the packaging film to form an unsealed packaging bag, then conducts longitudinal sealing through the longitudinal sealer, and then passes through the transverse sealer to seal the bag. After the longitudinal seal, the bottom of the packaging bag is sealed horizontally, and then the horizontal sealer is used to seal the top horizontally after the food is loaded. The lapel hollow former, the vertical sealer and the horizontal sealer have strict coordination requirements, and the entire forming and sealing is more complicated. , two horizontal seals are required successively, resulting in low efficiency of the entire forming and sealing, and the sealing effect is not good
