Description

Technical Field

[0001] The utility model relates to the technical field of paper cutting, in particular to a paper cutting device for paper printing. Background Art

[0002] Paper is a thin sheet made of plant fiber, used for writing, printing books and newspapers, packaging, etc., such as printing paper, carbon paper, toilet paper, facial tissue, etc. When paper is produced and printed, a slitting device is needed to cut the paper for later printing. A slitting machine is a mechanical device that cuts wide paper into multiple narrow papers of a certain width as required.

[0003] At present, when the slitting device is in use, it is necessary to change the position and number of the cutters according to the width requirements of the paper. The cutters of the existing slitting device are generally fixed to the shaft sleeve by bolts. It is necessary to use tools to dismantle the bolts corresponding to each cutter before the corresponding cutter can be removed or the position can be adjusted. The whole process is relatively cumbersome, especially when multiple cutters on the shaft sleeve need to be adjusted in position, it takes a long time, which affects the paper slitting efficiency.

[0035] Reference Figure 1-5 , a paper slitting device for paper printing, used for paper slitting, in order to facilitate the adjustment of the circular cutter position.

[0036] The paper-printed paper slitting device comprises a bracket 1, two rotating shafts 4, a rotating rod 5, a clamping strip 13, a circular cutter 6 and two fasteners 12;

[0037] A rotating box 3 is rotatably connected to both sides of the top of the bracket 1. Two rotating shafts 4 are rotatably connected to the two rotating boxes 3 respectively and their axes coincide. A clamping block 401 is provided at one end of the two rotating shafts 4 close to each other. The rotating rod 5 is arranged between the two rotating shafts 4 and has a clamping slot at both ends. Each clamping block 401 is adapted to a clamping slot so that each clamping block 401 can be inserted into a clamping slot, so that the two rotating shafts 4 are connected to the rotating rod 5 and can rotate together. A strip groove is provided on one side of the rotating rod 5. One side of the clamping strip 13 is arranged in the strip groove and the other side is provided with a plurality of fixed grooves 1301 arranged at intervals along the length direction. A through hole is provided in the middle of the circular cutter 6, and the circular cutter 6 is sleeved on the outside of the rotating rod 5 through the through hole.

[0038] A threaded through hole is provided on one side of the rotating rod 5, and the threaded through hole is connected to the strip groove. The fastener 12 is a fastening screw and is threadedly connected to the rotating rod 5 at the threaded through hole. A fixing hole is provided in the middle of the clamping block 401. One end of the fastener 12 passes through the fixing hole, and is inserted into the strip groove to press against one side of the clamping strip 13 and push the other side of the clamping strip 13 out of the strip groove. A fastening groove is provided on the side wall of the through hole of the circular cutter 6, and the fastening groove is adapted to the fixing groove 1301. When one end of the fastener 12 pushes the other side of the clamping strip 13 out of the strip groove, the fastening groove and the fixing groove 1301 are interlocked with each other, so that the clamping strip 13 and the circular cutter 6 are fixed. The rotating shaft 4 can drive the rotating rod 5 to rotate, thereby driving the circular cutter 6 to rotate together.

[0039] A driving motor 2 is provided on one side of the rotating box 3, and the output shaft of the driving motor 2 is connected to the rotating shaft 4. A rotating roller 7 is rotatably connected between the two rotating boxes 3. A toothed disc is provided on the rotating roller 7 and the rotating shaft 4. A chain is provided on the outside of the two toothed discs. The toothed disc and the chain are both located inside the rotating box 3. Two supporting rollers 11 are rotatably connected to the bracket 1. The two supporting rollers 11 are respectively located below the circular cutter 6 and the rotating roller 7. The driving motor 2 can drive the rotating shaft 4 to rotate, thereby driving the rotating rod 5 to rotate, so that the circular cutter 6 rotates, and the paper on the bracket is cut into widths. The rotating roller 7 can be driven to rotate through the transmission of the toothed disc and the chain. The paper is clamped between the supporting roller 11 and the rotating roller 7, which is convenient for the transportation of the paper, thereby facilitating the cutting of the paper.

[0040] In addition, in order to facilitate the length cutting of paper, an electric push rod 8 is provided on the bracket 1, and a movable plate 10 is provided on the top of the push rod of the electric push rod 8, and a cross-cutting knife 9 is provided at the bottom of the movable plate 10. The movable plate 10 is driven to rise and fall by the electric push rod 8, thereby driving the cross-cutting knife 9 to move up and down to cross-cut the paper on the bracket 1.

[0041] The working principle of the paper slitting device for paper printing is as follows: when in use, the two rotating boxes 3 are rotated upward to drive the circular cutter 6 and the rotating roller 7 to move upward away from the bracket 1, and then the paper to be cut is placed on the bracket 1, and the rotating box 3 is reset. At this time, the paper is clamped between the circular cutter 6 and the supporting roller 11 and the rotating roller 7 and another supporting roller 11. The rotating shaft 4 is driven by the driving motor 2 to rotate, so that the rotating rod 5 can be rotated, thereby driving the circular cutter 6 to rotate together to cut the paper, and the rotating roller 7 can be driven to rotate through the transmission of the toothed disk and the chain, so as to facilitate the transportation and cutting of the paper;

[0042] When the position of the circular cutter 6 needs to be adjusted, the two fasteners 12 are loosened to make one end of the fasteners 12 leave the strip groove of the rotating rod 5. At this time, the clamping strip 13 can enter the strip groove, so that the clamping strip 13 is separated from the circular cutter 6, and all the circular cutters 6 can be moved on the rotating rod 5 to adjust the position of each circular cutter 6. After the position adjustment is completed, the two fasteners 12 are tightened to make one end of the fasteners 12 enter the strip groove of the rotating rod 5, so that one side of the clamping strip 13 is pushed out of the strip groove, and the clamping strip 13 is pressed. Since one side of the clamping strip 13 is pushed out, the fastening groove on the circular cutter 6 and the fixing groove 1301 are mutually embedded, so that the clamping strip 13 and the circular cutter 6 are fixed;

[0043] When the number of circular cutters 6 needs to be replaced, the two fasteners 12 are loosened and removed. At this time, the fastener 12 leaves the fixing hole of the block 401, the block 401 can be separated from the slot of the rotating rod 5, and the rotating rod 5 can be directly removed. At this time, the circular cutters 6 are added or reduced on the rotating rod 5, and after the position is adjusted, the block 401 is inserted into the slot of the rotating rod 5 again, and finally the fastener 12 is tightened. One end of the fastener 12 passes through the fixing hole, so that the block 401 is fixed, so that the rotating shaft 4 is fixedly connected to the rotating rod 5.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
