Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to an upper film-walking packaging machine without scratches. Background Art

[0002] With the rapid development of the packaging industry and the increasing attention of humans to environmental pollution, degradable films such as aluminum films and paper films have become the main choice of packaging materials. However, when traditional packaging machines package packaging films such as aluminum films and paper films, it is necessary to use a cylindrical film bag former or a cylindrical film forming and folding mechanism to fold the two sides of the packaging film towards the middle to form a cylindrical film that communicates front and back. Inevitably, scratches will be generated on the packaging film during the operation of the cylindrical film bag former or the cylindrical film forming and folding mechanism, resulting in an unattractive packaging appearance and thus a decline in packaging quality.

[0003] In the existing patent, a Chinese patent document with the application number 202322087486.4 applied by the applicant on August 3, 2023 discloses an automatic bubble bag packaging machine, which includes a conveying mechanism, a folding mechanism, a heat sealing mechanism, a cutting and sealing mechanism, a film feeding mechanism and a workbench. The folding mechanism, the heat sealing mechanism and the cutting and sealing mechanism are sequentially arranged on the workbench along the feeding direction. The conveying mechanism is arranged on one side of the workbench and upstream of the folding mechanism. The film feeding mechanism is arranged on the other side of the workbench and downstream of the cutting and sealing mechanism. The folding mechanism includes a flattening assembly, a film feeding channel and a folding plate. The flattening assembly includes a flattening roller and an alignment roller. The flattening assembly is arranged below the workbench. The alignment roller is located on one side of the flattening roller. The film feeding channel is arranged on the upper end surface of the workbench and is connected to the conveying channel through the folding plate. During the process of folding the packaging film into a cylindrical film by the folding mechanism, the folding plate of the folding mechanism will generate scratches or creases on the packaging film, thus affecting the packaging quality. Therefore, the defect is very obvious and a solution is urgently needed. Summary of the Utility Model

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide an upper film-walking packaging machine without scratches.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An upper film-running non-scratch packaging machine, which comprises a machine table, a support base installed on the machine table, a film feeding mechanism installed on the support base, a film running mechanism installed on the support base and located below the film feeding mechanism, a cylindrical film forming mechanism arranged on the machine table, a middle sealing mechanism installed on the machine table and located below the discharging part of the cylindrical film forming mechanism, a knife sealing mechanism arranged outside the discharging end of the cylindrical film forming mechanism, and a discharging mechanism connected to the knife sealing mechanism. The cylindrical film forming mechanism includes a seat body installed on the machine table, a film folding and forming guide plate installed in the middle of the seat body, a cylindrical film forming channel installed on the seat body and connected to the discharging end of the film folding and forming guide plate, and a film guiding roller rotatably connected to the seat body and horizontally arranged above the feeding end of the film folding and forming guide plate. The film folding and forming guide plate and the cylindrical film forming channel are connected to form a V-shaped folding guide groove. A middle sealing groove communicating with the converging tip of the V-shaped folding guide groove is arranged in the middle of the cylindrical film forming channel. The middle sealing mechanism is located below the middle sealing groove. A through hole is arranged in the middle of the seat body, and the through hole communicates with the V-shaped folding guide groove. The film folding and forming guide plate is located above the through hole.

[0007] Further, a feeding channel is arranged in the middle of the film folding and forming guide plate, and the discharging end of the feeding channel communicates with the cylindrical film forming channel.

[0008] Further, the upper film-running non-scratch packaging machine further includes a feeding mechanism, and the discharging end of the feeding mechanism communicates with the feeding end of the feeding channel.

[0009] Further, an isosceles sharp-angle plate is arranged in the middle of the discharging end of the film folding and forming guide plate, a V-shaped opening is recessed in the middle of the feeding end of the cylindrical film forming channel, the V-shaped opening communicates with the middle sealing groove, and the isosceles sharp-angle plate extends into the V-shaped opening to form a V-shaped folding guide groove.

[0010] Advantages of the present utility model: In practical applications, after the packaging film supplied by the film feeding mechanism passes around the film guiding mechanism, the cylindrical film forming mechanism folds the two sides of the packaging film in half to form a cylindrical film. The middle sealing mechanism seals the folded part of the cylindrical film to complete the middle sealing of the cylindrical film. At the same time, the feeding mechanism conveys materials into the feeding channel, and the materials move along the feeding channel to the cylindrical film forming channel, so that the materials enter the formed cylindrical film. The middle-sealed cylindrical film and the materials enter the blade sealing mechanism together. The blade sealing mechanism seals and cuts the cylindrical film to form individual packaging bags and seals the materials in the packaging bags. The discharging mechanism outputs the packaging bags. During the process of the cylindrical film forming mechanism folding the packaging film in half, the packaging film output by the film guiding mechanism passes around the film guiding roller and moves along the film folding forming guide plate. Since during machine adjustment, the two sides of the packaging film at the film folding forming guide plate are bent downward and gradually folded in half in advance, and enter the middle sealing groove along the V-shaped folding guiding groove, during the movement of the packaging film along the film folding forming guide plate, using the flexibility of the packaging film itself, the two sides of the subsequent packaging film will bend downward and gradually approach and fold until the packaging film enters the middle sealing groove through the V-shaped folding guiding groove to form the packaging film into a cylindrical film, and the middle sealing mechanism seals the folded part of the cylindrical film. By improving the structure of the cylindrical film forming mechanism, the present utility model makes it difficult or impossible for the formed cylindrical film to have creases or scratches, improving the packaging quality.

[0017] As Figures 1 to 3As shown in the figure, the utility model provides an upper film - walking non - scratch packaging machine, which includes a machine table 1, a support base 2 installed on the machine table 1, a film - feeding mechanism 3 installed on the support base 2, a film - walking mechanism 4 installed on the support base 2 and located below the film - feeding mechanism 3, a cylindrical film forming mechanism 5 arranged on the machine table 1, a middle - sealing mechanism 6 installed on the machine table 1 and located below the discharging part of the cylindrical film forming mechanism 5, a knife - sealing mechanism 7 arranged outside the discharging end of the cylindrical film forming mechanism 5, and a discharging mechanism 8 connected to the knife - sealing mechanism 7. The cylindrical film forming mechanism 5 includes a seat body 9 installed on the machine table 1, a film folding and forming guide plate 10 installed in the middle of the seat body 9, a cylindrical film forming channel 11 installed on the seat body 9 and connected to the discharging end of the film folding and forming guide plate 10, and a film guiding roller 12 rotatably connected to the seat body 9 and horizontally spanning above the feeding end of the film folding and forming guide plate 10. The film folding and forming guide plate 10 and the cylindrical film forming channel 11 are connected to form a V - shaped folding guide groove 13. A middle - sealing groove 14 communicating with the converging tip of the V - shaped folding guide groove 13 is arranged in the middle of the cylindrical film forming channel 11. The middle - sealing mechanism 6 is located below the middle - sealing groove 14. A through - hole 15 is arranged in the middle of the seat body 9, and the through - hole 15 communicates with the V - shaped folding guide groove 13. The film folding and forming guide plate 10 is located above the through - hole 15.

[0018] Specifically, a feeding channel 16 is arranged in the middle of the film folding and forming guide plate 10, and the discharging end of the feeding channel 16 communicates with the cylindrical film forming channel 11. The upper film - walking non - scratch packaging machine further includes a feeding mechanism 17, and the discharging end of the feeding mechanism 17 is connected to the feeding end of the feeding channel 16.

[0019] In practical applications, after the packaging film supplied by the film feeding mechanism 3 passes around the film guiding mechanism 4, the cylindrical film forming mechanism 5 folds the two sides of the packaging film in half to form a cylindrical film.

The middle sealing mechanism 6 seals the folded part of the cylindrical film. The present utility model improves the structure of the cylindrical film forming mechanism 5, so that the formed cylindrical film is not easy to or will not generate creases or scratches, improving the packaging quality.

A V-shaped opening 19 is recessed in the middle of the feeding end of the cylindrical film forming channel 11. The V-shaped opening 19 is communicated with the middle sealing groove 14. The isosceles pointed angle plate 18 extends into the V-shaped opening 19 to form the V-shaped folding guiding groove 13. This structural design is conducive to forming the V-shaped folding guiding groove 13.

[0021] Specifically, the film feeding mechanism 3, the middle sealing mechanism 6, the knife sealing mechanism 7, and the discharging mechanism 8 can all adopt corresponding existing devices, which will not be elaborated here.

[0022] Specifically, the film guiding mechanism 4 can adopt a paper guiding mechanism, which will not be elaborated here.

[0023] All technical features in this embodiment can be freely combined according to actual needs.

[0024] The above embodiments are preferred implementation schemes of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
