Description

TECHNICAL FIELD

[0001] The utility model belongs to paper bag machine technical field, especially relate to a coiled material cutting device. BACKGROUND

[0002] In the process of realizing the utility model, the utility model person found that prior art at least has following problem:

[0003] The existing roll paper slitting machine technology is mostly the cutting principle of the plate cutting machine, and the upper cutter and the lower cutter form a certain angle. Unlike the plate cutting machine, the upper cutting knife rotates, and the lower cutting knife is fixed. During cutting, the contact process of the upper and lower cutting edges is that one side is cut off first, and the other side has not contacted the edge. With the progress of the cutting process, the position of the cut gradually changes from one side to the other side until it is completely cut off, which is similar to the process of cutting paper with scissors. This method will make the cutting time of the left and right sides of the cut roll inconsistent, which will easily lead to the cutting of the sheet being a parallelogram, and the four sides are not perpendicular. At the same time, due to the rotation of the upper cutter and the fixation of the lower cutter, the cutting gap between the two cutters is used for cutting, which requires precise adjustment of the cutting gap between the upper and lower cutters. If the adjustment is not proper, the cutter is easy to be hit. It needs certain experience and technology to adjust it well.

[0004] The existing tooth cutting technology is mostly that the upper cutter is a tooth cutter, and the lower cutter seat has a groove. The upper tooth cutter and the lower cutter seat are respectively fixed on the upper cutting knife shaft and the lower cutting knife shaft. During the cutting process, the upper and lower cutting knife shafts run synchronously to ensure that the upper tooth cutter can be accurately inserted into the groove of the lower cutter seat, and the cutting speed is faster than the running speed of the roll material. The cutting process is that the roll material is first pierced by the tooth cutter, and then the roll material is pulled apart due to the faster cutting speed than the running speed of the roll material. In this way, the cutting edge of the cut sheet is serrated.

[0005] CN206840275U-Roll paper slitting machine and swing combination for roll paper slitting machine discloses a roll paper slitting machine and swing combination for roll paper slitting machine, solves the problem that the sheet paper is easy to bend and fold irregularly during conveying to the paper collecting part, and the technical scheme is that the swing combination for roll paper slitting machine comprises a machine frame, a swing rod rotatably connected to the machine frame, a power source for controlling the swing rod to swing back and forth, and a plurality of swing plates uniformly fixed on the swing rod and swinging back and forth with the swing rod to beat the paper and prevent the middle part of the paper from hanging down and bending.

[0047] One of the technical solutions in the above technical scheme has the following advantages or beneficial effects: it is a sheeting technology for cutting a roll material into sheets, which can be used for both flat cutting and tooth cutting; when flat cutting, the gap between the upper cutter and the lower cutter does not need to be adjusted, and the upper cutter can be directly cut on the lower cutter shaft or the lower cutter seat, which is simple and convenient to use.

[0048] After adopting the above scheme, it is a sheeting technology for cutting a roll material into sheets, which can be used for both flat cutting and tooth cutting. When flat cutting, the gap between the upper cutter and the lower cutter does not need to be adjusted, and the upper cutter can be directly cut on the lower cutter shaft or the lower cutter seat, which is simple and convenient to use. At the same time, when cutting, the whole cutter is directly cut on the roll material, and there is no situation that the left and right sides are not cut synchronously, and the cut material is a neat rectangle. When a tooth-shaped cut is needed, only the tooth cutter and the lower tooth cutter seat need to be replaced. Align the recesses of the upper cutter and the lower cutter seat. If you want to be simpler, first align the tooth cutter and the tooth cutter seat, lock the phase of the upper and lower cutter shafts, replace the flat cutter with the flat cutter cutting on the flat cutter seat, and then replace the tooth cutter. Since the recesses of the tooth cutter and the tooth cutter seat were aligned the first time, the tooth cutter can be used directly after being replaced again. The whole mechanism only needs to be aligned once, and the flat cutter and the tooth cutter can be switched freely.
