Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to a cutting device for film processing, belonging to the technical field of film cutting. Background Technique

[0002] When packing large items or when there are high requirements for the cleanliness of the material storage surface, it is necessary to first lay a film and then package the items. In this case, it is usually necessary to manually cut the film. When cutting manually, the dimensional error is large, resulting in waste of the film. At the same time, the efficiency of manual cutting is low.

[0003] In the existing film cutting equipment, the film cannot be limited. When the film cutting is completed, the film will stick to the surface of the cutting blade and move up and down together with the cutting blade, thus affecting the subsequent film cutting work. This requires the operator to clean and peel off the film stuck to the surface of the cutting blade from the cutting blade after the film is cut to ensure the normal progress of the subsequent cutting work. This greatly reduces the work efficiency, and because the cutting blade is sharp, there is a safety hazard when the operator cleans it.

[0004] In summary, how to propose a cutting device for the above technical problems has become an urgent problem for those skilled in the art at present. Content of the Utility Model

[0046] Working Principle

[0047] Combined with Figures 1 to 7 The working principle of the present utility model is described as follows:

[0048] The operator pulls one end of the film, and the film on the unwinding roller 2 passes through the dust cleaning roller 3, the guiding roller 4 and the driving roller 5 in sequence, and then the stepping motor is started. The driving roller 5 transports the film towards the cutting unit. During the transportation of the film, under the action of the dust cleaning roller 3, the dust on the surface of the film is adsorbed, ensuring the discharging effect of the film.

[0049] The cutter 8 slides along the vertical section of the gantry 6 driven by the cylinder 7 to cut the film. When the cutter 8 rises and falls, the driving roller 5 stops transporting the film.

[0050] As Figure 1 , Figure 2 and Figure 7 shown, when the cutter 8 feeds towards the workbench 1, the piston rod 10 descends together with the slider 9. The piston rod 10 compresses the air in the piston cylinder 16, and then the air in the piston cylinder 16 is discharged through the first one-way valve. At the same time, the second one-way valve blocks the air in the piston cylinder 16 from entering the longitudinal pipe 11. After the cutter 8 cuts the film, the operator puts the cut film into the film collection box 21.

[0051] When the cutter 8 moves away from the workbench 1, the first one-way valve blocks the outside air from entering the piston cylinder 16. As the cutter 8 rises, the piston cylinder 16 extracts air from the one-way air guide cylinder 16-1, the longitudinal pipe 11 and each adsorption pipe 200, so that the ventilation holes form an adsorption force on the lower surface of the film, ensuring that when the cutter 8 rises, the film can be separated from the cutter 8, avoiding the situation that the film sticks to the cutter 8 and improving the stability of the cutting work.

[0052] When the cutter 8 rises to the highest point, the lever 10-1 abuts against the adjusting nut 410, and the lever 10-1 lifts the valve core of the second one-way valve upwards. At the same time, the piston cylinder 16 is communicated with the external atmosphere through the air leakage hole 300. The external atmosphere flows through the piston cylinder 16, the one-way air guide cylinder 16-1 and the longitudinal pipe 11 in sequence and then enters the adsorption pipe 200, so that the ventilation holes stop adsorbing the film. Then the driving roller 5 continues to transport the film towards the cutting unit, and so on, realizing the continuous cutting of the film.

[0053] The present utility model has been disclosed in the above preferred embodiment, but it is not intended to limit the present utility model. Any person skilled in the relevant art, without departing from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
