[0001] The utility model relates to the technical field of paper cup production, and specifically relates to a paper cup die-cutting machine. Background Technique

[0002] With the acceleration of the pace of life, the usage rate of disposable items has increased year by year. However, disposable items made of plastic are extremely difficult to degrade in nature. With the country's strong promotion of environmentally friendly materials, paper disposable items have gradually become popular. When producing paper cups, the bottom paper and the body paper of the paper cup are generally processed separately and then bonded. During the processing of the body paper, the printed cardboard needs to be cut into a fan shape that meets the process requirements.

[0003] The existing die-cutting machines have obvious deficiencies in terms of cutting efficiency. For example, in the utility model with the patent number CN214925086U, the designed cutting device can only achieve the single-cutting function during operation. This limitation has led to a significant extension of the overall production cycle during large-scale or continuous production. Since only single cutting can be performed, it cannot meet the needs of rapid production. This not only increases production costs but also may affect the progress arrangement of subsequent processes and the overall delivery time. Content of the Utility Model

[0024] Please refer to Figure 1-7, the present utility model provides a technical solution: a paper cup die-cutting machine, including a first housing 1. Inside the first housing 1, there is a pressure wheel 8. A number of bumps 16 are annularly arranged on the side of the pressure wheel 8. And a cardboard 3 is attached to the side of the pressure wheel 8. On the side of the cardboard 3 away from the pressure wheel 8, there is a cutting wheel 6 attached. A number of first sliding grooves 13 are annularly formed inside the cutting wheel 6. In each first sliding groove 13, there is a top block 9. On one side of each top block 9, there is a connecting rod 12 fixed. On the side of each connecting rod 12, there is a spring 10. One end of each connecting rod 12 away from the top block 9 is fixed with a limit block 23. On the side of the limit block 23 close to the spring 10, there is a loop buckle 14. On the same side of the pressure wheel 8 and the cutting wheel 6, there is a first limit ring 20. On the side of the pressure wheel 8 and the cutting wheel 6 away from the first limit ring 20, there is a second limit ring 22 sleeved. Inside the first housing 1, there is a motor 11. The output end of the motor 11 is sleeved with a driving gear 18. On the side of the driving gear 18, there is a first transmission gear 17 meshed. The first transmission gear 17 is sleeved on one end of the cutting wheel 6 close to the first limit ring 20. On the side of the first transmission gear 17, there is a second transmission gear 19 meshed. The driving gear 18 drives the first transmission gear 17 to rotate, thereby pushing the second transmission gear 19 to rotate. The first transmission gear 17 and the second transmission gear 19 drive the cutting wheel 6 and the pressure wheel 8 to rotate respectively.

[0025] Further, at both ends of the cardboard 3 inside the first housing 1, there are a number of guide rollers 7 for assisting the movement of the cardboard 3.

[0026] Further, there is an annular groove 24 inside the cutting wheel 6. On the annular groove 24, a number of second sliding grooves 15 are annularly formed inside the cutting wheel 6. The annular groove 24 is used to fix the snap ring, and the second sliding grooves 15 provide a moving space for the connecting rods 12.

[0027] Further, on one side of the first housing 1, there is a second housing 2 for protecting the first transmission gear 17 and the second transmission gear 19.

[0028] Further, on one side of the first housing 1 beside the cutting wheel 6, there is a guiding groove 4. On both opposite sides of the guiding groove 4, there are a number of fixing blocks 21 fixed. The guiding groove 4 is used to guide the cut cardboard 3 to the collection place, and the fixing blocks 21 fix the guiding groove 4 on the first housing 1.

[0029] Further, on the side of the first housing 1 away from the second housing 2, there is a side plate 5 for facilitating the maintenance of the device.

[0030] Working principle: Before the starting device starts, pass the cardboard 3 through between a number of material guiding rollers 7, and finally press it between the pressing wheel 8 and the cutting wheel 6. Then start the motor 11. The rotation of the motor 11 drives the rotation of the driving gear 18. The rotation of the driving gear 18 pushes the first transmission gear 17 to rotate. The rotation of the first transmission gear 17 drives the rotation of the cutting wheel 6. At the same time, the first transmission gear 17 drives the second transmission gear 19 to rotate, and the second transmission gear 19 drives the pressing wheel 8 to rotate. The cardboard 3 arranged between the pressing wheel 8 and the cutting wheel 6 moves along with the rotation of the pressing wheel 8 and the cutting wheel 6.

[0031] The bump 16 located on the pressing wheel 8 cooperates with the first chute 13 on the cutting wheel 6 to cut the cardboard 3. When the bump 16 enters the inside of the first chute 13, it pushes the top block 9 downward. The cut cardboard 3 is pressed by the bump 16 inside the first chute 13. When the bump 16 leaves the first chute 13, the spring 10 on one side of the top block 9 pushes the top block 9 upward until the surface of the top block 9 is flush with the surface of the cutting wheel 6. At this time, the cardboard 3 leaves the cutting wheel 6 and slides out of the first housing 1 through the guiding groove 4. At the same time, the limiting block 23 arranged at the end of the connecting rod 12 fixed to the side surface of the top block 9 is blocked by the snap ring, and finally the top block 9 is restricted from being pushed upward by the spring 10 continuously, preventing the top block 9 from being pushed away from the cutting wheel 6.

[0032] It should be noted that: The entire device is controlled by the total control device. Since the devices matched with the control device are common devices and belong to the existing mature technologies, the electrical connection relationship and the specific circuit structure are not described in detail here.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
