Floating type film punching device

Abstract

The invention discloses a floating type film punching device. The floating type film punching device comprises a rotating roller and floating type punching assemblies. According to the floating type film punching device, a plurality of floating type punching assemblies are evenly installed on a traditional rotating roller, floating of floating threaded sleeves is driven through rotation of adjusting screw rods, in this way, floating strip-shaped plates are driven to float in containing grooves in the radial direction, finally punching needles are driven to enter or stretch out of the containing grooves, when the punching distance in the length direction of a film is large, the two rows of punching needles which are arranged at intervals can be selected to be adjusted to enter the containing grooves, so that the two rows of punching needles entering the containing grooves lose the punching function, and the punching distance is increased.

Description

technical field [0001] The invention relates to a floating film punching device. Background technique [0002] At present, in the technological process of various plastic film processing, in order to meet the needs of packaging, it is often necessary to punch various plastic films. Earlier, punching was done manually, but the speed of punching holes was slow. , and uneven, the size of the punched holes is different, and it is easy to miss. For this reason, a periodic rotation punching is developed by setting a punching needle on the rotating roller, which greatly improves the automation and efficiency of punching. However, according to the needs of different packaging fields, types, and objects, sometimes the spacing of the holes punched in the length direction of the film needs to be adjusted, and the existing punching needles are generally fixed directly on the rotating roller. The lengthwise spacing of the perforations cannot be adjusted if the film is changed, so it can...

[0002] At present, in the technological process of various plastic film processing, in order to meet the needs of packaging, it is often necessary to punch various plastic films. Earlier, punching was done manually, but the speed of punching holes was slow. , and uneven, the size of the punched holes is different, and it is easy to miss. For this reason, a periodic rotation punching is developed by setting a punching needle on the rotating roller, which greatly improves the automation and efficiency of punching. However, according to the needs of different packaging fields, types, and objects, sometimes the spacing of the holes punched in the length direction of the film needs to be adjusted, and the existing punching needles are generally fixed directly on the rotating roller. The lengthwise spacing of perforations cannot be adjusted if the film changes, so it cannot be adjusted according to the perforation spacing in the film length direction. In addition, it is also necessary to realize the adjustment of the punching spacing in the film width direction.
