Description

Technical Field

[0001] This utility model relates to the field of paper product cutting technology, and in particular to a paper product cutting device that can accurately position the cutting process. Background Technology

[0002] In the printing, production, or handcrafting process, paper often has excess edges or bleed areas (parts beyond the design range). Cutting can remove these excess parts, making the finished product edges neat. After cutting, the paper edges are normal straight lines, which helps to align and even out the printed content and improve print quality. Cutting devices are generally used during cutting, but most paper product cutting devices in the current technology still have problems that need to be solved.

[0003] Most existing paper product cutting devices struggle to pinpoint the exact location where the paper product needs to be cut. Typically, operators manually adjust the cutting blade's position. However, manual adjustments are susceptible to visual judgment, experience, and operational proficiency, leading to cutting position deviations and impacting quality control. Therefore, it is necessary to design a paper product cutting device capable of accurate positioning to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a paper product cutting device that can accurately position the cutting process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A paper product cutting device capable of accurate positioning includes an operating table. A mounting frame is fixedly connected to the top of the operating table. Two fixed seats are fixedly connected to the bottom of the mounting frame. A common drive screw is rotatably connected to the two fixed seats. A screw nut is fitted onto the drive screw, and the screw nut is adapted to the drive screw. A movable seat is fixedly connected to the outer wall of the screw nut. A mounting plate is fixedly connected to the bottom of the movable seat. A signal receiver is fixedly connected to the bottom of one end of the mounting plate. A cutting mechanism is provided at the bottom of the mounting plate. A baffle is fixedly connected to the top of one end of the operating table. Side plates are fixedly connected to the top of both ends of the operating table. Two round rods are fixedly connected to one side of the baffle. A movable block is fitted onto the round rod. The movable block is slidably connected to the round rod. Two fixed rods are fixedly connected to the two movable blocks on their adjacent sides. The four fixed rods are fixedly connected to a common connecting plate. A [missing information - likely a device or mechanism] is fixedly connected to the top of the connecting plate. The laser emitter has a laser marker fixedly connected to the bottom of the connecting plate at the end furthest from the laser emitter. By using the marking line emitted by the laser marker to locate the cutting position, and through the cooperation of the laser emitter and signal receiver to position the cutting blade, the cutting mechanism can be stopped when the signal receiver receives the laser signal emitted by the laser emitter, thus moving the cutting blade to the cutting position. This effectively solves the problem mentioned in the background art that most existing paper product cutting devices struggle to locate the cutting position of the paper product. Generally, the operator manually adjusts the cutting blade position, which is easily affected by visual judgment, experience, and operational proficiency, leading to cutting position deviations and affecting quality control. Therefore, this technology significantly improves the accuracy of the cutting position, enabling the cutting blade to stop precisely at the preset cutting position, effectively reducing deviations caused by operational errors.

[0007] As a further embodiment of this utility model, a guide rod is provided on the movable seat, the guide rod is fixedly connected to two fixed seats, and the movable seat is slidably connected to the guide rod.

[0008] As a further embodiment of this utility model, the cutting mechanism includes a cutting blade, two limiting rods are fixedly connected to the top of the cutting blade, the top of the two limiting rods are fixedly connected to the same lifting plate, a fixing frame is provided on the top of the lifting plate, the fixing frame is fixedly connected to the top of the mounting plate, a cylinder is fixedly connected to the top of the fixing frame, and the output end of the cylinder is fixedly connected to the lifting plate.

[0009] As a further embodiment of this utility model, the limiting rod passes through the mounting plate, and the limiting rod is slidably connected to the mounting plate.

[0010] As a further embodiment of this utility model, a fixed platform is provided on both sides of the connecting plate, and an electric telescopic rod is fixedly connected to the top of the fixed platform. The output end of the electric telescopic rod passes through the fixed platform and is fixedly connected to a pressure plate. The fixed platform is sleeved on the fixed rod, and the fixed platform is fixedly connected to the fixed rod.

[0011] As a further embodiment of this utility model, a movable rod is fixedly connected to the top of both ends of the pressure plate, the movable rod passes through the fixed platform, and the movable rod is slidably connected to the fixed platform.

[0012] As a further embodiment of this utility model, a mounting platform is fixedly connected to the bottom of one end of the mounting bracket, and a servo motor is fixedly connected to the mounting platform. The output end of the servo motor and the drive screw are connected by a coupling.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes a laser marker to position the cutting location using a marking line emitted by a laser marker. By coordinating the laser emitter and signal receiver to position the cutting blade, the cutting mechanism stops moving when the signal receiver receives the laser signal, allowing the cutting blade to be moved to the cutting position. This effectively solves the problem mentioned in the background art where most existing paper product cutting devices struggle to accurately position the cutting location. Typically, operators manually adjust the cutting blade position, which is susceptible to errors due to visual judgment, experience, and skill level, leading to deviations in the cutting position and affecting quality control. This invention significantly improves the accuracy of the cutting position, ensuring the cutting blade stops precisely at the preset cutting position and effectively reducing deviations caused by operational errors.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1 - Figure 5A paper product cutting device capable of accurate positioning includes an operating table 1. A mounting frame 2 is fixedly connected to the top of the operating table 1. Two fixed seats 3 are fixedly connected to the bottom of the mounting frame 2. A single drive screw 4 is rotatably connected to the two fixed seats 3. A screw nut 5 is fitted onto the drive screw 4, and the screw nut 5 is adapted to the drive screw 4. A movable seat 6 is fixedly connected to the outer wall of the screw nut 5. A mounting plate 7 is fixedly connected to the bottom of the movable seat 6. A signal receiver 8 is fixedly connected to the bottom of one end of the mounting plate 7. A cutting mechanism 9 is provided at the bottom of the mounting plate 7. A baffle 10 is fixedly connected to the top of one end of the operating table 1. Side plates 20 are fixedly connected to the top of both ends of the operating table 1. Two round rods 11 are fixedly connected to one side of the baffle 10. A movable block 12 is fitted onto the round rod 11, and the movable block 12 is slidably connected to the round rod 11. Two fixed rods 13 are fixedly connected to the two movable blocks 12 on their adjacent sides. The four fixed rods 13 are fixedly connected to the same connecting plate 14. The top of the connecting plate 14 is fixedly... A laser emitter 15 is fixedly connected, and a laser marker 16 is fixedly connected to the bottom of the connecting plate 14 at the end away from the laser emitter 15. Because the laser marker emits a marking line to locate the cutting position, and the laser emitter and signal receiver work together to position the cutting blade, the cutting mechanism can stop moving when the signal receiver receives the laser signal emitted by the laser emitter, thus moving the cutting blade to the cutting position. This effectively solves the problem mentioned in the background art that most existing paper product cutting devices struggle to locate the cutting position of the paper product. Generally, the operator manually adjusts the cutting blade position, which is easily affected by visual judgment, experience, and operational proficiency, leading to cutting position deviations and affecting quality control. Therefore, this method significantly improves the accuracy of the cutting position, enabling the cutting blade to stop precisely at the preset cutting position, effectively reducing deviations caused by operational errors.

[0024] In this embodiment, a guide rod 601 is provided on the movable seat 6. The guide rod 601 is fixedly connected to two fixed seats 3, and the movable seat 6 is slidably connected to the guide rod 601.

[0025] In this embodiment, the cutting mechanism 9 includes a cutting blade 901. Two limiting rods 902 are fixedly connected to the top of the cutting blade 901. The top of the two limiting rods 902 is fixedly connected to the same lifting plate 903. A fixing frame 904 is provided on the top of the lifting plate 903. The fixing frame 904 is fixedly connected to the top of the mounting plate 7. A cylinder 905 is fixedly connected to the top of the fixing frame 904. The output end of the cylinder 905 is fixedly connected to the lifting plate 903.

[0026] In this embodiment, the limiting rod 902 passes through the mounting plate 7 and is slidably connected to the mounting plate 7. When the cutting blade 901 moves up and down, it will drive the limiting rod 902 to move along the mounting plate 7, ensuring the stability of the cutting blade 901 when it moves.

[0027] In this embodiment, a fixed platform 18 is provided on both sides of the connecting plate 14. An electric telescopic rod 17 is fixedly connected to the top of the fixed platform 18. The output end of the electric telescopic rod 17 passes through the fixed platform 18 and is fixedly connected to a pressure plate 19. The fixed platform 18 is sleeved on the fixed rod 13. The fixed platform 18 is fixedly connected to the fixed rod 13. When passing through, the pressure plate 19 descends to press down on the paper product, ensuring the stability of the paper product when it is cut.

[0028] In this embodiment, both ends of the pressure plate 19 are fixedly connected to a movable rod 23. The movable rod 23 passes through the fixed platform 18 and is slidably connected to the fixed platform 18. When the pressure plate 19 moves, it will drive the movable rod 23 to move along the fixed platform 18, ensuring the stability of the pressure plate 19 when it moves up and down.

[0029] In this embodiment, a mounting platform 21 is fixedly connected to the bottom of one end of the mounting bracket 2, and a servo motor 22 is fixedly connected to the mounting platform 21. The output end of the servo motor 22 and the drive screw 4 are connected by a coupling.

[0030] Working Principle: During use, place the paper product to be cut on the operating table 1, between the two side plates 20, with the side of the paper product not to be cut against the baffle 10. Activate the laser emitter 15, signal receiver 8, and laser marker 16. The signal receiver 8 is connected to the external PLC controller via a wire. The laser marking line emitted by the laser marker 16 determines the position. Move the laser marking line of the laser marker 16 to the position on the paper product where it needs to be cut. The lateral distance between the marking line of the laser marker 16 and the laser signal emitted by the laser emitter 15 is the same as the distance between the receiver of the signal receiver 8 and the cutting blade 901. Activate the laser emitter 15, causing it to emit a laser signal. This activates the servo motor 22 via the external PLC controller. The output of the servo motor 22 drives the coupling to rotate, which in turn drives the drive screw 4 to rotate. The drive screw 4 then moves the screw nut 5, which in turn moves the moving seat 6 along the guide rod 601. The movement of the moving seat 6... Moving the mounting plate 7 causes the limit rod 902 to move, which in turn moves the cutting blade 901. The movement of the mounting plate 7 also moves the signal receiver 8. When the signal receiver 8 receives the laser signal from the laser emitter 15, its built-in processor processes the signal and feeds it back to the PLC controller. The PLC controller then stops the servo motor 22, moving the cutting mechanism 9 directly above the area of ​​the paper product that needs to be cut, thus activating the output of the electric telescopic rod 17. When the end of the electric telescopic rod 17 extends, it will drive the pressure plate 19 to move, causing the pressure plate 19 to descend and press down on the paper product, ensuring stability during cutting. When the output end of the cylinder 905 extends, the lifting plate 903 will descend, which will drive the limit rod 902 to descend. The limit rod 902 will drive the cutting blade 901 to descend, thus cutting the paper product. After cutting, the cutting blade 901 will be moved back to the initial position, causing the pressure plate 19 to rise and not contact the paper product, so that the cut paper product can be taken out.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
