[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figures 1 to 3The present invention provides an embodiment of an automatic paper cutting device for roll paper production, comprising a mounting plate 1, which primarily supports the entire device and provides a stable foundation. Support plates 2 are fixedly connected to the top and left and right sides of the mounting plate 1. Support plates 2 are mounted on the top and left sides of the mounting plate 1 to support and stabilize the entire device, ensuring the balance of all components during operation.
[0033] The top right edge of the right support plate 2 is fixedly connected to a mounting bracket 3. This bracket 3 is secured to the top edge of the right support plate 2, providing a secure mounting position for the motor 4. This enhances the overall structural strength of the device. The top edge of the mounting bracket 3 is fixedly connected to the motor 4. The drive end of the motor 4 is fixedly connected to a guide roller 5, the core component that drives the entire system. Through its connection to the guide roller 5, the motor 4 controls the transmission and cutting of the paper roll. The left and right outer edges of the guide roller 5 are rotatably connected to the center of the top edges of the two support plates 2, defining the rotational position of the guide roller 5.
[0034] refer to Figure 2 、 Figure 3 The two support plates 2 are fixedly connected to adjacent sides with a limit rod 6. This limit rod 6 is installed between the two support plates 2, limiting the range of motion of the lower pressure plate 7, ensuring that it can only slide up and down to achieve a precise cutting effect. The two limit rods 6 are externally slidably connected to the lower pressure plate 7. The left and right sides of the lower pressure plate 7 are slidably connected to the adjacent sides of the two support plates 2. The bottom end of the lower pressure plate 7 is detachably connected to the cutter 8. The lower pressure plate 7 is connected to the cutter 8 and is responsible for driving the cutter 8 to move downward steadily and press it against the support plates 2, ensuring the stability of the paper during the cutting process. Its up and down movement directly affects the cutting effect of the cutter 8.
[0035] The top and left and right sides of the lower pressing plate 7 are fixedly connected to positioning blocks 9, and the middle of the positioning blocks 9 is rotatably connected to a gravity disk 10. The positioning blocks 9 are fixed to the top of the lower pressing plate 7 and are rotatably connected to the gravity disk 10, so that it can float up and down through centrifugal force, driving the cutting process. The gravity disk 10 has a chute 11 inside, and an eccentric disk 12 is rotatably connected inside the chute 11. The eccentric disk 12 has a through groove 13 in the middle and a chute 11 inside. The gravity disk 10 is connected to the eccentric disk 12 and floats up and down through the action of centrifugal force, directly affecting the movement of the lower pressing plate 7.
[0036] The left and right exteriors of the guide roller 5 are fixedly connected to the inner walls of the through-slot 13. The through-slot 13 connects the eccentric disc 12 to the guide roller 5, securing the guide roller through its inner walls and ensuring stable operation of the entire device. Auxiliary plates 14 are slidably connected to the exteriors of the two limit rods 6. Mounted beneath the lower pressure plate 7 and cutter 8, these plates provide a fixed platform to stabilize the paper during cutting. The left and right sides of the auxiliary plates 14 are slidably connected to adjacent sides of the two support plates 2, allowing for adjustable positioning of the auxiliary plates 14.
[0037] A cutting groove 15 is defined at the top of the auxiliary plate 14. The bottom end of the cutter 8 engages with the inner wall of the cutting groove 15. The cutting groove 15, located at the top of the auxiliary plate 14, provides a precise cutting position for the cutter 8, ensuring a neat cut. Mounting holes 23 are defined on both the left and right sides of the mounting plate 1. Multiple mounting holes 23 are defined on the mounting plate 1 to facilitate securing the device at a specific location on the paper roll production line.
[0038] refer to Figure 4 , and 5, auxiliary components are fixedly connected to the front and rear sides of the lower pressing plate 7. The auxiliary components include four positioning sleeves 16, which are fixedly connected to the four outer corners of the lower pressing plate 7. A positioning sleeve 16 is fixed to the left and right ends of the front and rear sides of the lower pressing plate 7. A positioning shaft 17 is fixedly connected to the middle of the positioning sleeve 16. The outer portion of the positioning shaft 17 is rotatably connected to the telescopic rod 18. The positioning shaft 17 is connected to the telescopic rod 18 and is responsible for guiding the up and down movement of the telescopic rod 18, helping to control the movement of the pressing rod 22.
[0039] The top of telescopic rod 18 is slidably connected to the inner wall of positioning sleeve 16. Spring 19 is mounted on the outer sleeve of telescopic rod 18. Spring 20 is fixedly connected to the top of positioning shaft 17. Positioning sleeve 16 and spring 20 cooperate to limit the rotational angle of the top of telescopic rod 18. The top of spring 20 is fixedly connected to the top of the inner wall of positioning sleeve 16. A fixing ring 21 is fixedly connected to the bottom of telescopic rod 18. One end of spring 19 is fixedly connected to the outside of positioning shaft 17, and the other end of spring 19 is fixedly connected to the outside of fixing ring 21. The action of springs 19 and 20 adjusts the vertical movement of pressure rod 22 to accommodate paper of varying thicknesses. A pressure rod 22 is fixedly connected to the middle of the two fixing rings 21. Positioning rod 22 is located below lower pressure plate 7 and is responsible for supporting both sides of the paper, ensuring paper stability during cutting and preventing deformation and damage.
[0040] Working principle: When in use, the device is installed at a suitable position on the paper roll production line through the mounting hole 23 of the mounting plate 1. When the paper roll is rolled to a suitable thickness, the motor 4 can be controlled to start, and the motor 4 drives the guide roller 5 to drive the eccentric disk 12 to rotate with the through slot 13 as the center to generate centrifugal force, and the centrifugal force of the through slot 13 will drive the attraction disk 10 to float up and down, and because the top of the attraction disk 10 is connected to the lower pressure plate 7 and the cutter 8 through the positioning block 9, and the lower pressure plate 7 is limited by the limit rod 6 to only slide up and down in a straight line, the attraction disk 10 will drive the lower pressure plate 7 and the cutter 8 through the positioning block 9 to cut the paper sliding between the lower pressure plate 7 and the auxiliary plate 14, thereby replacing the manual cutting method in the traditional process and effectively reducing the risk of manual injury.
[0041] As the lower pressure plate 7 and cutter 8 press downward, the pressure rod 22, which is lower than the lower pressure plate 7, is driven to press against the two sides of the paper roll, allowing the paper roll to fit the top of the auxiliary plate 14. As the pressure rod 22 contacts the paper, it is driven by the paper to cause the top of the telescopic rod 18 to press against the spring 2 20, causing it to tilt slightly. The telescopic rod 18 and spring 1 19 then slightly expand and contract. The elastic potential energy of springs 19 and 20 then resets the pressure rod 22 to press against the two sides of the paper, allowing the paper to fit the top surface of the auxiliary plate 14. This assists the cutter 8 fixed to the lower pressure plate 7 to press down and overlap the cutting groove 15 to cut the paper, ensuring the integrity of the paper roll cut. This process ensures that the paper is not damaged by pulling through the expansion and contraction of the pressure rod 22.
[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
