Paper manufacturing cutting device

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] See Figure 1-4 The present invention provides a technical solution: a paper manufacturing cutting device, comprising a swing rod 3, a push-pull rod 8 and a cutting box 17, the inner surface of the cutting box 17 is movably sleeved with a fixed shaft 4 through a bearing 23, so The fixed shaft 4 is fixed at the center of the pendulum rod 3. A positioning pillar 2 is welded on the side of the pendulum rod 3 close to the upper end, and the positioning pillar 2 is sleeved with the pillar groove 6, and the pillar groove 6 is arranged in a circle. On one side of the disc 1, a power shaft 7 is fixed at the center of the disc 1, and a motor 20 is connected to the other side of the power shaft 7, and the motor 20 is fixed to the inner surface of the cutting box 17 through a fixed base 21 The bottom end of the pendulum rod 3 is fixedly connected with a separating sleeve 19, a movable shaft 5 is sleeved at the center of the separating sleeve 19, and a push-pull rod 8 is sleeved on both sides of the movable shaft 5, so The outer surface wall at the center of the push-pull rod 8 is sheathed with a guide post 9, and a cutting board 16 is sheathed on one side of the guide post 9 through the push-pull rod 8. The cutting board 16 is fixed on the inner surface wall of the cutting box 17. The end of the tie rod 8 is welded with a cutter fixing block 13, and the lower end of the cutter fixing block 13 is screwed with a cutting knife 15 through a fastening bolt 14, and the inner surface of the cutting box 17 is sleeved with a power shaft 7 through a bearing 23, A paper roll 10 is fixed on the outer wall of the power shaft 7, a paper 11 is wound on the outer wall of the paper roll 10, and the paper 11 passes through the space between the two push-pull rods 8 and the slot 18 respectively.

[0022] The outer surface wall of the power shaft 7 at the center of the disc 1 is movably sleeved with a bearing 23, a suspension rod 22 is fixed above the bearing 23, and the upper surface wall of the suspension rod 22 is fixed to the upper surface wall of the cutting box 17, Play the role of support. There are two guide posts 9 in total, and push-pull rods 8 are movably sleeved at the centers of the two guide posts 9, and the guide posts 9 are fixed inside the cutting box 17, mainly for guiding and The role of the fixed position, the width of the column slot 6 is equal to the diameter of the positioning column 2, the disk 1 can use the column slot 6 to drive the positioning column 2 to move during the rotation process, the motor 20 and The external power supply is electrically connected, and a return spring 12 is fixed on one side of the cutting board 16, and the return spring 12 is sleeved on the outer wall of the push-pull rod 8.

[0023] Working principle: When the paper cutting device is used, the paper 11 is rolled on the outer wall of the paper roll 10, and then the paper 11 is passed through the middle position of the two push-pull rods 8 and the slot 8, and then the motor 20 is connected to the external power supply. Electrically connected, under the action of the power shaft 7, the paper roll 10 and the disc 1 perform a rotating movement, and the disc 1 drives the pendulum rod 3 to swing through the column slot 6, and under the action of the force, the push-pull rod 8 pushes and pulls Movement, through the guiding action of the guide post 9 and the cutting board 16, the cutting knife 15 moves left and right, and cuts the paper 11 during the movement, and falls out of the slot 18.

[0024] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
