Problems solved by technology

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 top is sealed by the horizontal sealer after the food is loaded. The lapel hollow former, the vertical sealer and the horizontal sealer have strict requirements for cooperation. For food packaging, the entire forming and sealing in the packaging process is relatively complicated, and two horizontal sealings need to be carried out successively, resulting in low efficiency of the entire forming and sealing, and the sealing effect is not good

Embodiment 1

[0035] see figure 1 , a method for forming and sealing food packaging, comprising successively a bag forming step, a longitudinal sealing step and a horizontal sealing step, the bag forming step is to fold the whole roll of packaging film into a square film bag by the bag forming part 1; the horizontal sealing step The front end of the vertically sealed square film bag filled with materials is cornered and heat-sealed through the knife-sealing corner part 2, and the rear end of the square film bag is cut off first, and then corners are cornered and heat-sealed to obtain the finished product.

[0036] This embodiment is the most basic implementation mode. In the bag forming step and the longitudinal sealing step, the bag forming parts and the longitudinal sealing parts of the prior art can be used, and the film bag conveying parts of the prior art can be used in the film bag conveying process. The whole roll of packaging film is folded into a square film bag by the bag form...

Embodiment 2

[0038] see figure 1 , a method for forming and sealing food packaging, comprising successively a bag forming step, a longitudinal sealing step and a horizontal sealing step, the bag forming step is to fold the whole roll of packaging film into a square film bag by the bag forming part 1; the horizontal sealing step The front end of the vertically sealed square film bag filled with materials is cornered and heat-sealed through the knife-sealing corner part 2, and the rear end of the square film bag is cut off first, and then corners are cornered and heat-sealed to obtain the finished product.

[0039] In the longitudinal sealing step, the middle sealing part 3 is used to seal the square film bag containing the materials in the middle.

[0040] This embodiment is a preferred implementation mode. The longitudinal sealing step is to seal the square film bag containing the material in the middle through the middle sealing part, which can adjust the regularity of the packaging mater...

Embodiment 3

[0042] see figure 1 , a method for forming and sealing food packaging, comprising successively a bag forming step, a longitudinal sealing step and a horizontal sealing step, the bag forming step is to fold the whole roll of packaging film into a square film bag by the bag forming part 1; the horizontal sealing step The front end of the vertically sealed square film bag filled with materials is cornered and heat-sealed through the knife-sealing corner part 2, and the rear end of the square film bag is cut off first, and then corners are cornered and heat-sealed to obtain the finished product.

[0043] In the longitudinal sealing step, the middle sealing part 3 is used to seal the square film bag containing the materials in the middle.

[0044] A film bag conveying step is also arranged between the longitudinal sealing step and the horizontal sealing step. The film bag conveying step is to form an adsorption on the square film bag containing materials after the film bag negative...

Abstract

The invention discloses a form-seal method for food packaging. The method sequentially includes the steps of a bag forming process, a vertical sealing process and a transversal sealing process, wherein the bag forming process includes folding an entire roll of packaging film into square film bags through a bag forming unit, the transversal sealing process includes performing corner inserting and heat-sealing to the front ends of the square fill bags filled with food after being vertically sealed, by a knife-sealing corner-inserting unit, cutting the rear ends of the square film bags in advance, then performing corner inserting and heat-sealing to obtain the finished products. During the transversal sealing process, the vertically sealed square film bags can be successively subjected to end corner inserting and sealing by adopting the knife-sealing corner-inserting unit, and thereby the efficiency of forming and sealing of a whole package is improved and the sealing effect is better.

Description

technical field [0001] The invention relates to a food packaging method, in particular to a food packaging forming and sealing method. 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 handling, loading and unloading, ...
