A film cutting and pulling method suitable for material packaging

Abstract

The present invention discloses a film cutting and pulling method suitable for material packaging, and relates to the technical field of material packing techniques. The film cutting and pulling method comprises cutting a packaging film in a transportation process of the packaging film. In comparison with the conventional packaging methods, film cutting time is saved, and the packaging speed is thus raised. When the method is used for packaging materials of different specifications, the position of a film cutting mechanism does not need to be adjusted, the length of the packaging film only needs to be set in the system, and thus precision cutting of the packaging film can be carried out; and during packaging of materials of different specifications, time for adjusting machinery equipment is saved, and thus the efficiency of the whole packaging process is raised.

Description

technical field [0001] The invention relates to the technical field of material packaging technology, and more specifically relates to a film cutting and pulling method suitable for material packaging. Background technique [0002] The material packaging machine replaces the traditional manual packaging. It has the characteristics of fast speed, neat and beautiful packaging, which not only saves manpower but also improves production efficiency. However, with the continuous acceleration of people's life rhythm, the packaging speed of the existing material packaging machine can no longer meet people's needs. It is necessary to improve the packaging speed of the material packaging machine on the premise of ensuring the packaging quality, and the existing material packaging machine For materials of one specification, when packaging materials of different specifications, it is necessary to adjust the structure of the material packaging machine, and then pack materials of differen...

Problems solved by technology

[0005] Another example is that the film cutting mechanism of an existing material packaging machine adopts the structure of a gantry frame. The packaging film is transported from the film releasing station to the film cutting station, and then transported to the pushing bag mechanism through the vacuum film pulling mechanism. The structural film cutting mechanism is fixed on the gantry, and the gantry is equipped with an adjusting screw to adjust the height of the film cutting mechanism. When changing the packaging specification material, the position of the film cutting mechanism needs to be readjusted to ensure that the pattern on the packaging film is complete. Coated on the material so that the film cutting mechanism will not cut the pattern on the packaging film, but to achieve accurate cutting and accurately adjust the position of the film cutting mechanism, this adjustment process takes a lot of time and energy for workers. In some market competition environments, the packaging principle flow is: film conveying→film stop for the first time→cut the film→continue to convey to the top of the pushing mechanism→second stop→push the bag to push the material and packaging film to the forming cavity →Push the bag back to the initial position→Convey the second cut packaging film to the top of the pushing head. When the packaging specification needs to be changed, adjust the position of the film cutting mechanism→Find the film cutting point→Film conveying→The film stops for the first time→Cut off the film →Continue conveying to the top of the push bag mechanism→Second stop→Push the bag to push the material and packaging film to the forming cavity→Push the bag back to the initial position→Transfer the second cut packaging film to the top of the pushing head, reciprocating in turn

This kind of packaging machine not only has the problem that the packaging film transportation stops when the packaging film is cut, but also cannot meet the requirements of packaging materials with different specifications, and the adjustment time is too long, which reduces the packaging efficiency; at the same time, the existing structural form needs to be cut To adjust the position of the film mechanism, the gantry is required to fix the film cutting mechanism, and at the same time adjust the position of the film cutting mechanism through the adjusting screw on the gantry, the structure is complex

[0006] From the above situation, it can be known that the existing material packaging machines have low packaging speed and materials that cannot meet various specifications. When packaging materials with diverse specifications, the packaging efficiency is low, which brings inconvenience to the entire packaging process and affects the progress of the entire packaging process.
