Three-dimensional packaging machine

Abstract

The invention discloses a three-dimensional packaging machine. The three-dimensional packaging machine is characterized in that a thin film conveyed by a film conveying part passes through a float guide rail, and is downwards conveyed out by a traction guide roll at fixed length; a film cutting part is arranged under the traction guide roll, and is used for cutting the thin film at fixed length; a box feeding platform is arranged under the film cutting part, and a material push part is arranged at the back side of the box feeding platform, and is used for forwards pushing a row of paper boxes on the box feeding platform into a package forming passage; a left edge folding part, a right edge folding part, an upper edge folding part and a lower edge folding part are arranged on the package forming passage, the left edge folding part and right edge folding part are used for folding the left and right edges of a thin film package, and the upper edge folding part and lower edge folding part are used for folding the upper and lower edges of the thin film package; bottom sealing parts are arranged at the bottom parts of the left edge folding part and right edge folding part, and are used for sealing the bottom seals of the thin film package; side sealing parts are arranged at the front sides of the upper edge folding part and lower edge folding part and are used for sealing the side seals of the thin film package; a traction part is arranged at the bottom part of the package forming passage, and is used for forwards pushing and conveying the paper boxes in the package forming passage. The three-dimensional packaging machine has the advantages that the package quality is good, and the production speed is high; the problem of shutdown and material storage in the prior art is solved.

Description

technical field [0001] The invention relates to a three-dimensional packaging machine for film packaging a fixed number of cartons. Background technique [0002] The three-dimensional packaging machine is used for film packaging of a fixed number of cartons. The working principle of the three-dimensional packaging machine in the prior art is: the fixed number of cartons are stacked horizontally in a row and pushed into the packaging forming channel in the packaging machine by the pushing parts. When the box is pushed, the film blocking the front of the carton is cut to a fixed length and wraps the carton. At the same time, the film forms left and right hems under the action of the left and right hemming parts, and then the bottom sealing part seals the film packaging. , and then, the pushing part pushes the rear row of cartons and pushes the front row of cartons forward through the rear row of cartons, so the film packaging of the front row of cartons forms the upper and low...

AI Technical Summary

Problems solved by technology

[0003] The three-dimensional packaging machine of the prior art mainly has the following deficiencies: 1. In the three-dimensional packaging machine of the prior art, the forward action of the front row of cartons in the film packaging process is promoted by the rear row of cartons, so After the equipment is shut down, there will always be many rows of cartons still left in the packaging machine because there are no rear cartons to push them, so the packaging machine has the problem of stopping and storing materials. The cartons left in the packaging machine need to be taken out manually, which is troublesome to operate. The degree of automation is not high; in addition, since the forward movement of the front row of cartons during the film packaging process is driven by the rear row of cartons, the front and rear rows of cartons are close to each other, so that the packaging When the side sealing part of the machine performs side sealing on the film packaging of the front row of cartons, the film packaging of the front row of cartons and the film packaging of the rear row of cartons are prone to adhesion, so the packaging machine has side sealing Sticking problems, not only affect the quality of packaging, but also affect the speed of production

2. The three-dimensional packaging machine in the prior art generally performs the film unwinding action with a single unwinding reel, because it cannot realize the fast splicing action, so it cannot meet the high-speed production requirements of the three-dimensional packaging machine. In addition, the reel unwinds the film. The tension of the film is not easy to control stably when unwinding, so the packaging quality cannot be well guaranteed

3. In the existing three-dimensional packaging machine, the cut-to-length film is unwound on the film unwinding shaft, but when a roll of film is used up and needs to be docked with a new film, it cannot be spliced ​​quickly. film action, so it cannot meet the high-speed production requirements of three-dimensional packaging machines

4. In the existing three-dimensional packaging machine, the fixed-length cutting of the film is completed by the rolling cutting action of the upper and lower hobs. The cutting length of the film is not easy to control and adjust, the working noise is large, and the tool life is short, which cannot meet the requirements of the three-dimensional packaging machine. high-speed production requirements

5. In the three-dimensional packaging machine of the prior art, the pushing head of the pushing part must push the front row of cartons forward in the first half of the pushing action, and return according to the original path in the second half of the pushing action. During the entire pushing action time of the material head, the rear row of cartons cannot be filled in place, so the pushing time is longer, which cannot better meet the high-speed production requirements of the three-dimensional packaging machine

6. In the three-dimensional packaging machine of the prior art, the bottom sealing head of the bottom sealing part only moves up and down, and because the film is generally in a loose state before the bottom sealing of the film packaging, the bottom sealing The thin film packaging is often not tight, and the film at the bottom sealing part is also easy to wrinkle, which affects the packaging quality, and also limits the further improvement of the production speed of the three-dimensional packaging machine
