Description

Technical Field

[0001] This utility model relates to the field of paper cup processing, specifically to a paper cutting device for processing paper cups. Background Technology

[0002] Paper cup manufacturing is a process that blends traditional craftsmanship with modern technology. It begins with carefully selected environmentally friendly paper materials, which are then cut into pre-defined sizes using precision paper cutting equipment. These pieces are then pressed into a cup shape by forming machinery, and the edges are finely polished to ensure user comfort and safety. To enhance the durability and water resistance of the paper cups, some products also undergo a coating treatment.

[0003] The prior art disclosed in patent publication (announcement) number CN212422318U is a paper cutting device for paper cup processing, including a support frame. A processing table is installed at the top of the support frame. A cylinder and a fixed seat are respectively installed on both sides of the top of the processing table. The output end of the cylinder is connected to a push rod. One end of the push rod is connected to a push plate. A slanted fixing frame is installed at the top of the fixed seat. A hydraulic cylinder is connected to the bottom of one end of the slanted fixing frame. A hydraulic telescopic rod is connected to the output end of the hydraulic cylinder. A movable plate is connected to one end of the hydraulic telescopic rod. A linear guide rail is connected to the bottom end of the movable plate. Three sliding blocks are slidably connected on the linear guide rail. Limit blocks are connected to the sides of the sliding blocks, and cutting tools are connected to the bottom ends of the sliding blocks.

[0004] The aforementioned patent document discloses a paper cutting device for paper cup processing. While it solves the problems of traditional paper cutting devices that use a single blade for cutting, reducing cutting efficiency, and requiring manual pushing to remove the cut paper, posing a safety hazard of blade cuts, its shortcomings are:

[0005] When existing cutting equipment is in use, if the pressure applied by the hydraulic cylinder exceeds the safe range, the excessive pressure will directly act on the cutter. This may not only cause rapid wear of the cutter blade, but also cause deformation or even breakage of the cutter structure, thereby seriously damaging the overall performance and cutting accuracy of the cutting equipment. Furthermore, after the cutting operation is completed, the waste generated by the existing cutting equipment is often scattered all over the ground, which is very troublesome to clean up manually.

[0006] Therefore, we have made improvements to this and proposed a paper cutting device for processing paper cups. Utility Model Content

The rotating disk 603 will drive one end of the connecting rod 604 to make a circular motion, and the other end will be rotatably connected to the sliding rod 601. Then, the connecting rod 604 will drive the sliding rod 601 to slide back and forth in an orderly manner within the mounting frame 3.

[0048] In a preferred embodiment, four limiting rods 607 are fixedly installed on the upper surface of the movable plate 4, and all four limiting rods 607 are slidably connected to the mounting frame 3.

[0049] In this embodiment, a stable and flexible sliding connection is formed between the four limiting rods 607 and the mounting frame 3, which not only ensures the stability and directionality of the movable plate 4 during movement and avoids paper cutting errors caused by shaking or offset, but also greatly improves the smoothness and accuracy of the paper cutting operation.

[0051] In a preferred embodiment, the buffer mechanism 7 includes a sliding block 701, which is slidably connected inside the fixed cylinder 602. The sliding block 701 is fixedly connected to the lower end of the sliding rod 601, and a spring 702 is fixedly installed between the sliding block 701 and the bottom of the fixed cylinder 602.

[0052] In this embodiment, the buffer mechanism 7 is mainly composed of a sliding block 701, which is slidably connected inside the fixed cylinder 602, so that the sliding block 701 can slide flexibly inside the fixed cylinder 602 as the movable plate 4 moves up and down. The lower end of the sliding block 701 is firmly fixed to the sliding rod 601, ensuring their synchronous movement. A spring 702 is installed between the sliding block 701 and the bottom of the fixed cylinder 602. The spring 702 can absorb and disperse the impact force and vibration generated by the cutting action when the cutter 5 contacts and cuts the paper, thereby effectively buffering and protecting the cutter 5.

[0054] In a preferred embodiment, the waste winding mechanism 8 includes a first mounting plate 801 and a second mounting plate 802, and two of each of the first mounting plate 801 and the second mounting plate 802 are provided. The two first mounting plates 801 and the two second mounting plates 802 are fixedly mounted on one side surface of the mounting frame 3. A winding roller 803 is rotatably connected between the two first mounting plates 801, and a guide roller 804 is rotatably connected between the two second mounting plates 802.

These two pulleys are tightly connected by a durable connecting belt 807, ensuring that when the second rotating shaft 202 drives the conveyor belt 203, the take-up roller 803 rotates synchronously through the transmission action of the first pulley 805, the connecting belt 807, and the second pulley 806. This achieves immediate winding of waste material during the cutting process, preventing waste from scattering and accumulating.
