The present application sets the fixed plate, the movable plate and the cylinder. It solves the problem that the current slitting machine is more troublesome when replacing the roll paper shaft, which affects the working efficiency of the slitting machine. Although the present application and the comparative document both use the cutting knife and the circular knife to cooperate with the paper cutting mode, the specific paper cutting and adjusting mode are different. SUMMARY
[0004] In order to overcome the above problems, the present application provides a roll paper slitting machine fixing device, which can realize the position adjustment of the slitting knife and the maximum locking and fixing of the slitting knife, so as to realize the complete cutting of the roll paper.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a paper roll slitting machine fixing device, comprising a frame, the frame including a base and support plates disposed on both sides of the base, a paper feeding mechanism disposed between the two support plates, the paper feeding mechanism including a drive motor disposed on the frame and a paper feeding roller fixedly disposed on the output shaft of the drive motor; a slitting device disposed on the frame in front of the paper feeding roller, the slitting device including a sleeve disposed on the support plate, a fixing mechanism disposed inside the sleeve, a cutter bracket disposed on the sleeve and a cutter mechanism disposed on the cutter bracket; the fixing mechanism including a lead screw disposed on the sleeve, a mounting bracket fixedly disposed on the frame, and the lead screw connected to the mounting bracket, and a fixing handwheel and an adjusting handwheel respectively disposed on the lead screw on both sides of the mounting bracket.
[0006] This invention provides a fixing device for a roll paper slitting machine. This solution focuses on describing a portion of the structure of the roll paper slitting machine; other specific structures not involved in this technical solution are not described in detail (these structures belong to the prior art). The sleeve passes through the two support plates on the frame. The sleeve can be adjusted left and right relative to the support plates, and it can also be rotated to adjust the position of the cutting mechanism on the cutting blade bracket towards the paper feeding roller. The distance between the two can be adjusted according to the thickness of the roll paper. The mounting bracket is fixed to the right side wall of the support plate on the right side. When the left and right position of the cutting mechanism needs to be adjusted, the adjusting handwheel is manually rotated, thereby driving the lead screw to rotate. The rotation of the lead screw drives the sleeve, the cutting blade bracket, and the cutting mechanism to adjust their positions synchronously. When the adjustment is complete, the adjusting handwheel is manually fixed, and the fixing handwheel on the other side is rotated and tightened to completely lock the lead screw. This achieves maximum locking and fixing of the cutting blade while adjusting its position, thus achieving complete cutting of the roll paper.
[0007] Preferably, the cutter bracket includes two connecting rods disposed on the sleeve, a connecting post disposed between the two connecting rods, and a cutting mechanism including a plurality of circular blade holders disposed on the connecting post and circular blades disposed on the circular blade holders, with the circular blade holders arranged at equal intervals. The circular blade holders are fixedly disposed on the connecting post, and there are six in total. The circular blades are rotatably disposed on the circular blade holders and can rotate as the paper roll moves, simultaneously cutting the paper roll into multiple segments.
[0008] Preferably, a rotating shaft is rotatably provided between the two support plates located below the circular cutter, and a plurality of downward cutting circular cutters are equidistantly provided on the rotating shaft.
[0009] As preferred, the paper feeding rotating wheel is provided with a plurality of annular cutting grooves, which are arranged at equal intervals, and a protrusion is arranged in each cutting groove. The design of the protrusion can reduce the possibility of cutting paper scraps being rolled into the cutting groove and being difficult to clean.

The opening of the collecting box has a width greater than the diameter of the paper feeding rotating wheel and a length greater than the linear distance between the cutting grooves on the two sides of the paper feeding rotating wheel. The auxiliary support is arranged on the lower side of the paper feeding rotating wheel. When the paper feeding rotating wheel rotates to feed paper, the protrusion is driven to rotate and contact the stationary slide rod, and then moves relatively. The process is that the slide rod is gradually compressed to the maximum compression position and then gradually returns to the original position. This process can cut the rolled paper scraps in the paper feeding rotating wheel and then feed them into the collecting box for collection. The two side walls of the auxiliary support are provided with guide slopes, so that the paper scraps can be conveniently fed into the collecting box from the opening.
[0011] As preferred, the end of the protrusion is provided with a plurality of arc-shaped surfaces one, and the end of the slide rod is provided with a plurality of arc-shaped surfaces two.
