Description

Technical Field

[0001] This utility model relates to the field of paper cutter technology, and in particular to a high-speed paper cutter roller structure and its paper cutting mechanism. Background Technology

[0002] Paper cutters are traditional products used to handle paper cutting needs in the later stages of printing. Paper cutting machinery consists of household paper cutters and industrial paper cutters, with a wide variety of types and varying degrees of automation. Most of them use a conveyor platform to transport the paper, and then a related drive mechanism drives the cutting blades to move and cut the paper.

[0003] A search revealed Chinese Patent Publication No. CN220903531U, which discloses a paper cutting mechanism for a paper cutter. This device includes a fixed base, a conveyor platform fixedly connected to the top of the fixed base, a cutting frame fixedly connected to the top of the fixed base, a fixed sliding frame fixedly connected to the bottom of the inner cavity of the cutting frame, a sliding mechanism inside the fixed sliding frame, a cleaning component at the bottom of the sliding mechanism, a cutting blade fixedly connected to the bottom of the fixed sliding frame, and a control box fixedly connected to one side of the fixed sliding frame by bolts. The control box contains a drive mechanism. This application, through the coordinated use of the sliding mechanism, drive mechanism, and related components, offers simple overall operation, allowing for quick cleaning of the cutting blade surface, effectively avoiding the safety hazards of manual cleaning, and eliminating the need to shut down the entire cutting equipment, thus significantly improving its actual working efficiency.

[0004] However, in actual use, the ends of the paper tend to curl up during the cutting process. The curled paper is not easy to position and transport. Moreover, when the paper curls up, it is easy to shift or deviate during the subsequent transport process, which will cause it to stack up and affect the cutting process and quality. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-speed paper cutting roller structure and its cutting mechanism, aiming to improve the problems of unstable conveying and poor directionality in the cutting process of existing devices, which affect the output of materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-speed paper cutting roller structure, comprising a machine body, a feeding chamber fixedly installed on one side of the machine body, a second rotating rod provided on the inner side of the machine body, a roller body fixedly connected to the outer side of the second rotating rod, two first rotating rods rotatably installed on the inner side of the machine body, a plurality of pressure blocks fixedly installed on the outer surface of the two first rotating rods, and a positioning component provided inside the pressure block.

[0007] The above technical solution involves a conveying roller inside the machine body to transport the paperboard. By rotating the roller body, the roller body comes into contact with the surface of the paperboard, thus cutting the paper. The positioning component ensures the stability and directionality of the paperboard during the cutting process.

[0008] As a further description of the above technical solution:

[0009] The positioning component includes a telescopic spring and an arc-shaped block. The arc-shaped block is disposed at the bottom of the pressure block, and the top surface of the arc-shaped block extends into the interior of the pressure block. The telescopic spring is disposed inside the pressure block, and the bottom end of the telescopic spring is fixedly connected to the arc-shaped block.

[0010] Through the above technical solution: when the arc-shaped block rotates and contacts the top surface of the cardboard, the arc-shaped block will expand and contract inside the pressure block, thereby squeezing the telescopic spring. At the same time, the telescopic spring can push the arc-shaped block to move outward. When the arc-shaped block contacts the cardboard, the friction between the arc-shaped block and the cardboard can be increased, thereby positioning it and increasing the stability and directionality of the cardboard during the cutting process.

[0011] As a further description of the above technical solution:

[0012] Multiple first connecting belts are connected between the two first rotating rods via pulleys. A drive motor is fixedly installed on the outer surface of the machine body via a fixing frame, and the output end of the drive motor is connected to one of the first rotating rods.

[0013] Through the above technical solution: when one of the first rotating rods rotates, the other first rotating rod can be driven to rotate through multiple first connecting belts, thereby ensuring that the two first rotating rods rotate synchronously, at the same speed and in the same direction, thus ensuring the stable rotation of the two sets of pressure blocks and ensuring the stability of paper feeding.

[0014] As a further description of the above technical solution:

[0015] Multiple brushes are fixedly installed on the outer surface of the second rotating rod, and a cutting motor is fixedly installed on the outer surface of the machine body through a fixing frame, and the output end of the cutting motor is connected to the second rotating rod.

[0016] Through the above technical solution: when the second rotating rod rotates, it can drive the brush to rotate, and the brush rotates and contacts the cut cardboard, thereby increasing the friction between the brush and the cardboard, which in turn further increases the stability and directionality of the cardboard conveying.

[0017] As a further description of the above technical solution:

[0018] The inner side of the machine body is provided with a feeding roller, and the two sides of the feeding roller are symmetrically provided with transmission rods. One end of the two transmission rods is connected to a second connecting belt through a pulley. The outer side of the machine body is fixedly installed with a feeding motor through a fixing frame, and the output end of the feeding motor is connected to one of the transmission rods.

[0019] The above technical solution ensures that the two transmission rods rotate in the same direction and at the same speed through the second connecting belt. The transmission rods are in contact with the feeding rollers. When the transmission rods rotate, they can drive the feeding rollers to rotate. The feeding rollers make calendering contact with the paperboard, thereby ensuring the guidance of the paperboard during transportation.

[0020] As a further description of the above technical solution:

[0021] A conveyor motor is fixedly installed on the outside of the machine body via a mounting bracket, and a control panel is fixedly installed on the outer surface of the machine body.

[0022] The above technical solution allows for the control of opening and closing of various components via a control panel, and the conveyor motor can activate the internal conveyor rollers, ensuring the coordinated operation of the machine.

[0023] As a further description of the above technical solution:

[0024] A high-speed paper cutter with a roller structure further includes a fixed frame, two screws symmetrically arranged inside the fixed frame, a movable block passing through the screws, a connecting rod fixedly connected between the two movable blocks, and a pressure roller rotatably connected to the outer surface of the connecting rod.

[0025] Through the above technical solution: when the two screws rotate, they can drive the two moving blocks to move synchronously. The moving blocks can drive the connecting rod to rise and fall, and the connecting rod can drive the pressure roller to rise and fall. In this way, the height of the pressure roller can be adjusted, thereby controlling the pressure of the pressure roller on the paperboard, and thus adjusting the speed of paperboard conveying.

[0026] As a further description of the above technical solution:

[0027] Worm gears are fixedly connected to the top ends of the two screws, and a double-segment worm gear is meshed with one side of the two worm gears. A lifting motor is fixedly installed on the outside of the fixed frame through a fixing bracket, and the output end of the lifting motor is connected to the double-segment worm gear.

[0028] The above technical solution involves two sections of threaded double-segment worm gear meshing with two worm wheels. When the double-segment worm gear rotates, it ensures that the two worm wheels rotate synchronously in the same direction and at the same speed. When the two worm wheels rotate synchronously, it ensures that the two screws rotate synchronously, thereby ensuring the synchronicity of the movement of the two moving blocks.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, through the positioning component, when the first rotating rod rotates, the first rotating rod can drive the pressure block to rotate, and the pressure block drives the arc-shaped block at its bottom to rotate. The arc-shaped block can then contact the top surface of the cardboard. When the arc-shaped block contacts the cardboard, it will squeeze the telescopic spring inward, and at the same time, the telescopic spring will push the arc-shaped block outward. This allows the arc-shaped block to have sufficient friction with the cardboard. The rotation of the arc-shaped block can ensure stable paper feeding and can also position the direction of paper feeding, preventing deviation during paper feeding.

[0031] 2. This utility model utilizes a double-segment worm gear. The double-segment worm gear drives two worm wheels to rotate, which in turn drives two screws to rotate. The screws then drive two moving blocks to move, which in turn drive a connecting rod to rise and fall. This connecting rod can then drive the pressure roller to rise and fall, thereby adjusting the height of the pressure roller and, consequently, the pressure of the pressure roller on the paperboard. This, in turn, allows for the adjustment of the paperboard conveying speed, thus increasing the practicality of the device. Attached Figure Description

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a high-speed paper cutting roller structure, including a machine body 1, a feeding chamber 6 fixedly installed on one side of the machine body 1, a second rotating rod 10 provided on the inner side of the machine body 1, a roller body 16 fixedly connected to the outer side of the second rotating rod 10, two first rotating rods 9 rotatably installed on the inner side of the machine body 1, and a plurality of pressure blocks 18 fixedly installed on the outer surface of the two first rotating rods 9, with a positioning component 25 provided inside the pressure block 18;

[0044] Specifically, the machine body 1 is equipped with a conveyor roller for transporting cardboard. The conveyor roller consists of multiple rollers and is connected by a conveyor belt. The rotation of the conveyor belt drives the multiple conveyor rollers to rotate, thereby transporting the cardboard. Transporting items by conveyor rollers is a common technique in the industry, so it will not be described in detail here. In use, the cardboard can be placed inside the feeding chamber 6, and then the cardboard can be pulled out from inside the feeding chamber 6 for cutting.

[0045] Reference Figure 3 , Figure 6 and Figure 7The positioning component 25 includes a telescopic spring 2501 and an arc-shaped block 2502. The arc-shaped block 2502 is located at the bottom of the pressure block 18, and the top surface of the arc-shaped block 2502 extends into the interior of the pressure block 18. The telescopic spring 2501 is located inside the pressure block 18, and the bottom end of the telescopic spring 2501 is fixedly connected to the arc-shaped block 2502. Multiple first connecting belts 13 are connected between the two first rotating rods 9 through pulleys. A drive motor 3 is fixedly installed on the outer surface of the machine body 1 through a fixing frame, and the output end of the drive motor 3 is connected to one of the first rotating rods 9.

[0046] Specifically, the arc-shaped block 2502 is movably installed inside the pressure block 18. When one of the first rotating rods 9 rotates, it can drive the other first rotating rod 9 to rotate through multiple first connecting belts 13. The two first rotating rods 9 can drive the two sets of pressure blocks 18 to rotate synchronously, in the same direction, and at the same speed. When the pressure block 18 rotates, it can drive the arc-shaped block 2502 at the bottom to rotate. When the arc-shaped block 2502 rotates to the bottom, it will contact the top surface of the cardboard. When the arc-shaped block 2502 contacts the cardboard, its top will press the telescopic spring 2501 inward. At the same time, the telescopic spring 2501 can push the arc-shaped block 2502 outward through the reaction force. This can ensure that the arc-shaped block 2502 applies a certain friction force to the cardboard. When the arc frame rotates quickly, it can transport and position the cardboard, increasing the stability and directionality of the cardboard during transport and preventing the cardboard from deviating during transport, which would affect the cutting process.

[0047] Reference Figure 4 Multiple brushes 15 are fixedly installed on the outer surface of the second rotating rod 10, and a cutting motor 11 is fixedly installed on the outer surface of the machine body 1 through a fixing frame, and the output end of the cutting motor 11 is connected to the second rotating rod 10.

[0048] Specifically, when the second rotating rod 10 rotates, it can drive the brush and the roller body 16 on its surface to rotate. Both the roller body 16 and the brush 15 are in contact with the cardboard. The roller body 16 can cut the cardboard, and the brush 15 can increase the friction with the surface of the cardboard. When rotating, it can pull the cardboard out, which increases the stability of the cardboard output.

[0049] Reference Figure 5 The inner side of the machine body 1 is provided with a feeding roller 7, and the two sides of the feeding roller 7 are symmetrically provided with transmission rods 8. One end of the two transmission rods 8 is connected to a second connecting belt 17 through a pulley. The outer side of the machine body 1 is fixedly installed with a feeding motor 12 through a fixing frame, and the output end of the feeding motor 12 is connected to one of the transmission rods 8.

[0050] Specifically, the two transmission rods 8 are in contact with both sides of the conveyor roller. By rotating one of the transmission rods 8, the transmission rod 8 can drive the other transmission rod 8 to rotate via the second connecting belt 17. The two transmission rods 8 rotate synchronously, in the same direction and at the same speed, which can drive the conveyor roller 7 to rotate. The conveyor roller 7 performs calendering and conveying of the paperboard, ensuring the stability and directionality of the paperboard during conveying after cutting.

[0051] Reference Figure 1 and Figure 2 A conveyor motor 4 is fixedly installed on the outside of the machine body 1 via a fixing frame, and a control panel 2 is fixedly installed on the outer surface of the machine body 1.

[0052] Specifically, the conveyor motor 4 can control the switching of the conveyor rollers inside the machine body 1. The control panel 2 of this device is electrically connected to the drive equipment of this device, and the switch of the drive equipment can be controlled through the control panel 2. Since controlling the drive equipment through the control panel 2 is a common technical means used by industry professionals, its specific structure and electrical connection relationship will not be described in detail here.

[0053] Reference Figure 1 and Figure 8 A high-speed paper cutting mechanism with a roller blade structure further includes a fixed frame 5. Two screws 19 are symmetrically arranged inside the fixed frame 5. The screws 19 are connected to moving blocks 20. A connecting rod 23 is fixedly connected between the two moving blocks 20. A pressure roller 24 is rotatably connected to the outer surface of the connecting rod 23. Worm gears 22 are fixedly connected to the top ends of the two screws 19. A double-segment worm gear 21 is meshed with one side of the two worm gears 22. A lifting motor 14 is fixedly installed on the outer side of the fixed frame 5 through a fixing bracket, and the output end of the lifting motor 14 is connected to the double-segment worm gear 21.

[0054] Specifically, the movable block 20 is connected to the screw 19 by a thread, so that when the screw 19 rotates, it can drive the movable block 20 to move on the screw 19. The inner walls of the machine body 1 and the fixed frame 5 are provided with slots, and the movable block 20 and the screw 19 are set inside the slots, so as to ensure the stable rotation of the screw 19 and the stable movement of the movable block 20. When the movable block 20 moves, it can drive the connecting rod 23 to rise and fall. The rise and fall of the connecting rod 23 can adjust the height of the pressure roller 24, thereby adjusting the pressure of the pressure roller 24 on the paperboard. By adjusting the pressure of the pressure roller 24 on the paperboard, the output speed of the paperboard can be controlled, which increases the practicality of the device.

[0055] Working Principle: When using this device, place it in the designated position, put the paper to be cut inside the feeding chamber 6, and extend one side of the paper out of the discharge end of the machine body 1. Turn on the conveyor motor 4, which provides basic feeding of the paper. Turn on the cutting motor 11, which drives the second rotating rod 10 to rotate. The second rotating rod 10 drives the brush 15 and the roller body 16 to rotate. The roller body 16 can cut the paperboard, and the brush 15 can increase the friction with the paperboard, thereby ensuring stable paperboard discharge. Turn on the feeding motor 12, which drives the transmission rod 8 to rotate. The transmission rod 8 drives another transmission rod 8 to rotate through the second connecting belt 17. The two transmission rods 8 drive the feeding roller 7 to rotate, which performs calendering and feeding of the paperboard, ensuring the stability and directionality of the paperboard feeding. Turn on the drive motor 3, which drives the first rotating rod 9 to rotate. The first rotating rod 9 can drive another first rotating rod 9 to rotate through multiple first connecting belts 13. The two first rotating rods 9 drive the pressure block 18. The rotating pressure block 18 drives the arc-shaped block 2502 to rotate. When the arc-shaped block 2502 rotates to the bottom, it contacts the cardboard and simultaneously compresses the telescopic spring 2501 inward. The telescopic spring 2501 pushes the arc-shaped block 2502 in the opposite direction, thus ensuring the friction and pressure between the arc-shaped block 2502 and the cardboard. When the arc-shaped block 2502 rotates, it further increases the stability and directionality of the cardboard conveying, preventing the cardboard from deviating during conveying and affecting the cutting process. This is achieved by turning on the lifting motor. 14. The lifting motor 14 drives the double-section worm gear 21 to rotate, the double-section worm gear 21 drives the two worm wheels 22 to rotate, the worm wheels 22 drive the screw 19 to rotate, the screw 19 drives the moving block 20 to move, the moving block 20 drives the connecting rod 23 to rise and fall, and the connecting rod 23 drives the pressure roller 24 to rise and fall. This can adjust the pressure of the pressure roller 24 on the paperboard. By adjusting the pressure, the speed of paperboard conveying can be adjusted. When using this device, the stability and directionality of paperboard conveying are increased, and the speed of paperboard conveying can also be adjusted.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
