Description

Technical Field

[0001] The utility model relates to the technical field of paper cutting equipment, in particular to a paper cutting mechanism for a disposable paper cutting machine. Background Art

[0002] The disposable paper cutter can greatly improve production efficiency, ensure the quality of finished paper, and reduce waste in the production process.

[0003] Although today's technology has many advantages, its disadvantage is that the cutters of today's paper cutting mechanisms are mostly blade-down. The blade-down design can better utilize gravity, making the cutting process smoother and more efficient, but the blade-down design means that the blade is located below, which may require the operator to reach under the blade when replacing the blade, increasing the risk of injury. At the same time, when cutting paper, most of the time a separate power source is used to fix the paper. The independent power source can provide a stable fixing force to ensure that the paper does not move during the cutting process. However, if there is a problem with the control system of the paper cutter, such as a circuit failure or a software error, the cutter may start prematurely while the paper has not yet been fixed. If the paper is not fixed, the paper may move during the cutting process, resulting in an uneven or irregular cutting line, affecting the appearance and quality of the finished product, increasing the scrap rate, and increasing production costs.

[0037] like Figure 5 , Figure 6 and Figure 8As shown, multiple fixed blocks 27 are evenly divided into two groups, and the two groups of fixed blocks 27 are fixedly connected to the outer surfaces of the two moving blocks 23. The fixed blocks 27 can provide support for the positioning pins 28, so that the clamping block 26 can make a circular motion with the positioning pins 28 as the center.

[0038] like Figure 7 As shown, the limiting mechanism includes two clamping blocks 1 21, and the inner surfaces of the two installation grooves 12 are each provided with a clamping groove 20. The clamping block 1 21 can position the protective cover 14 to prevent the protective cover 14 from being misplaced when the device is running, thereby affecting the normal use of the device.

[0039] like Figure 5 , Figure 6 and Figure 8 As shown, multiple springs 230 are fixedly connected to the bottom of multiple tooth plates 29, and multiple springs 230 are fixedly connected to the top of the workbench 1. The springs 230 can provide power for the reverse movement of the tooth plates 29, so that the tooth plates 29 move to the initial position.

[0040] like Figure 5 , Figure 6 and Figure 8 As shown, two sliders 33 are movably embedded in the inner surfaces of two slide grooves 35, and multiple telescopic rods 31 are movably embedded in the inner surface of the workbench 1. The slide grooves 35 can limit the moving trajectory of the sliders 33, avoiding the derailment of the sliders 33 and affecting the use of the equipment.

[0041] like Figure 1 , Figure 3 and Figure 7 As shown, the outer surfaces of the two fixing columns 13 are provided with a card slot 19, and the two card blocks 1 21 are movably embedded in the inner surfaces of the two card slots 20 and the card slot 1 19. The cooperation between the fixing columns 13 and the mounting grooves 12 can support the protective cover 14 and provide a good working environment for the protective cover 14.

[0042] Working principle: This device is a paper cutting mechanism for a disposable paper cutter. In terms of protecting the staff, when replacing the cutter, first remove the bolt 9 on the positioning block 8, then move the block 21 out of the slot 20 and the slot 19, then hold the handle 15, put the fixing column 13 into the two installation slots 12, and then insert the block 21 back into the slot 20 and the slot 19 to prevent the protective cover 14 from shaking when the equipment is running, then remove the bolt 2 16, and then install the bolt 9, so that the bolt 9 squeezes the rubber gasket 18 on the cutter 17, so that the positioning block 8 and the cutter 17 become a whole. When replacing the cutter, the staff can directly use the handle 15 to replace the protective cover 14 together with the cutter 17, avoiding the contact between the staff and the cutter 17, causing the cutter 17 to endanger the health of the staff, and start The hydraulic cylinder 3 on the working frame 2 causes the telescopic rod 4 to move downward, and the telescopic rod 4 drives the rotating shaft 6 to move downward on the inner surface of the slide groove 10 through the fixed block 5, and the rotating shaft 6 drives the gear 7 and the positioning block 8 to move downward together. When the gear 7 moves to engage with the tooth plate 11, because the number of teeth of the tooth plate 11 is half of the number of teeth of the gear 7, when the gear 7 engages with the tooth plate 11, the gear 7 will rotate 180 degrees while moving downward, and then the gear 7 drives the rotating shaft 6 to rotate 180 degrees while moving downward, and then the positioning block 8 drives the cutter 17 to rotate 180 degrees, so that the cutting edge of the cutter 17 rotates from the upward position to the downward position, thereby avoiding the cutting edge of the cutter 17 being downward inside the protective cover 14, avoiding the operator from extending his hand under the cutter 17, and further ensuring the health of the staff.

[0043] When cutting the paper, the elastic coefficient of the second spring 30 is much smaller than the elastic coefficient of the first spring 25, and the rotating shaft 6 will first drive the moving block 23 at the annular groove 22 to move downward, so that the moving block 23 drives the positioning plate 24 to move downward. When the block 26 and the tooth plate 29 are in contact for the first time, the force exerted by the paper on the lower pressure plate 34 is relatively small, and the block 26 will first be stuck on the top of the tooth plate 29, so that the rotating shaft 6 indirectly drives the tooth plate 29 to move downward while moving downward. As the tooth plate 29 moves downward, the tooth plate 29 The second 29 will squeeze the spring second 30 and the telescopic rod second 31, so that the spring second 30 is compressed and obtains elastic potential energy. The limit plate 32 can prevent the telescopic rod second 31 from moving upward excessively. The spring second 30 of the workbench 1 provides power for the tooth plate second 29 to move back to the initial position. The tooth plate second 29 drives the slider 33 to move on the inner surface of the slide groove second 35, and drives the lower pressure plate 34 to squeeze the paper. When the paper is squeezed to a state where it can no longer be pressed down, the shaft 6 will continue to move downward, and then the card block second 26 will continue to move downward, but Due to the obstruction of tooth plate 29, block 26 makes a circular motion with the positioning pin 28 on fixed block 27 as the center, thereby deforming spring 1 25. Spring 1 25 provides power for block 26 to restore its initial state, and then shaft 6 can drive cutter 17 to continue to move downward to cut the paper. When the cutting is completed, shaft 6 drives cutter 17 to move upward. If the factory power is interrupted at this time, block 26 will be stuck on the teeth of tooth plate 29, because the teeth of tooth plate 29 are sufficient. Therefore, the cutter 17 will not move down to damage the cut paper, and the maximum height of the paper to be cut is much lower than the height of the tooth plate 29. Therefore, even if the cutter 17 has moved out of the height of the tooth plate 29 and then the factory power is suddenly interrupted, the clamping block 26 will be stuck on the tooth plate 29, and the cutter 17 will not contact the cut paper. Furthermore, when the factory power is interrupted, the cutter 17 will not damage the paper due to moving down, thereby ensuring the quality of the paper and reducing the production cost to a certain extent.

[0044] The above is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
