Description

Technical Field

[0001] This utility model relates to the field of paper printing technology, specifically a novel paper printing position control device. Background Technology

[0002] In the fields of cigarette packaging, hygiene product packaging, and roll label printing, roll paper (i.e., roll-shaped substrate) is the core printing carrier. Its printing quality directly determines the appearance consistency, information integrity, and market acceptance of the end product. Among them, the accuracy of printing position is a key indicator of roll paper printing. If the pattern, text, or positioning mark is misaligned, it will result in visual defects of the product, or even cause subsequent cutting misalignment, packaging seal failure, batch scrapping, and significantly increase production costs.

[0003] Traditional disc printing involves long-term conveying and printing, which can easily cause the disc to loosen during transport, leading to the deviation of the printed pattern. Furthermore, manual correction is inefficient and inaccurate. Relying on operators to manually adjust the pattern by visually observing the deviation is slow to respond and the adjustment accuracy depends entirely on experience, making it difficult to adapt to high-speed production. At the same time, it is prone to errors due to fatigue.

[0004] Therefore, this utility model provides a novel paper roll printing position control device to solve the above problems. Utility Model Content

[0024] 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.

[0025] This utility model provides a novel paper roll printing position control device, such as... Figure 1-6As shown, the novel paper roll printing position control device includes two sets of frames 1, with a base 2 fixedly installed between the two sets of frames 1. A drive assembly 3 is fixedly installed on the upper side of each of the two sets of frames 1, and a take-up and release roller 4 is installed between each of the two sets of drive assemblies 3. A printing assembly 5 is fixedly installed on the upper side of the base 2. Two sets of tension rollers 6 are rotatably installed inside the right end of the base 2. A turntable 7 is rotatably installed inside the right end of the base 2. A first drive motor 8 is fixedly installed on the rear side of the base 2. The output shaft of the first drive motor 8 is fixedly connected to the turntable 7. Slide grooves 14 are symmetrically opened at the front and rear ends of the turntable 7. Adjusting sliders 17 are slidably installed in the left and right ends of the two sets of slide grooves 14. Two sets of tension adjusting rollers 18 are rotatably installed between the adjusting sliders 17 in the left and right ends of the two sets of slide grooves 14. An adjusting assembly is provided inside the turntable 7.

[0026] In actual operation, when the device is started, the first drive motor 8 drives the turntable 7 to rotate, which in turn drives the two sets of tension adjusting rollers 18 to rotate. Through the operation of the adjustment component, the distance between the two sets of tension adjusting rollers 18 is finely adjusted, thereby achieving precise control of the tension during the paper conveying process. Through the fine adjustment of the adjustment component, it is ensured that the paper maintains an appropriate tension during the conveying process, effectively preventing the printing pattern offset problem caused by loose conveying.

[0027] The adjustment assembly includes a second drive motor 9, which is fixedly mounted on a turntable 7. Rotary shafts 10 are rotatably mounted on the upper sides of both ends of the turntable 7. Synchronous pulleys 11 are fixedly mounted on the upper ends of both sets of rotating shafts 10, and synchronous belts 12 are sleeved on the two sets of synchronous pulleys 11. First bevel gears 13 are fixedly mounted on the lower ends of both sets of rotating shafts 10. First bidirectional screws 15 are rotatably mounted in both sets of sliding grooves 14. Second bevel gears 16 are fixedly mounted on both sets of first bidirectional screws 15, and the two sets of second bevel gears 16 mesh with the two sets of first bevel gears 13. The left and right ends of the two sets of first bidirectional screws 15 are connected to four sets of adjusting sliders 17 via threads.

[0028] The output shaft of the second drive motor 9 drives two sets of rotating shafts 10, two sets of synchronous pulleys 11 and synchronous belts 12 to rotate, which in turn drives two sets of first bevel gears 13 and two sets of second bevel gears 16 meshing with the two sets of first bevel gears 13 to rotate, which in turn drives two sets of first bidirectional screws 15 to rotate. At the same time, the adjusting sliders 17 sleeved at the left and right ends of the two sets of first bidirectional screws 15 slide in the two sets of sliding grooves 14, which in turn drives two sets of tension adjusting rollers 18 to move. As components that are in direct contact with the paper roll, the fine adjustment of the position of the two sets of tension adjusting rollers 18 can achieve precise control of the tension of the paper roll.

[0029] Two sets of guide rods 19 are fixedly installed in the lower end of the base 2. A second bidirectional screw 20 is rotatably installed in the lower end of the base 2. Limiting brackets 21 are sleeved on the two sets of guide rods 19. The two sets of limiting brackets 21 are connected to the second bidirectional screw 20 by threads. Limiting plates 22 are provided on the upper ends of the left and right sides of the two sets of limiting brackets 21.

[0030] By rotating the second bidirectional screw 20, the two sets of limiting frames 21 slide on the two sets of guide rods 19. The limiting plates 22 at the upper left and right sides of the two sets of limiting frames 21 limit the width of the paper roll, thereby achieving precise control over the left and right positions of the paper roll and preventing lateral deviation during transport, further improving the accuracy of the printing position. Simultaneously, the limiting plates 22 increase the contact area with the paper roll, improving the stability of the device's support for the paper roll and ensuring its smooth transport.

[0031] The limiting plates 22 on the upper left and right sides of the two sets of limiting frames 21 are flush with the two sets of tension rollers 6, and the limiting plates 22 on the upper left and right sides of the two sets of limiting frames 21 are respectively located on opposite sides of the two sets of tension rollers 6.

[0032] Two sets of tension rollers 6 flatten the paper roll during the tension adjustment by rotating the turntable 7 and two sets of tension adjusting rollers 18 driven by the output shaft of the first drive motor 8, ensuring that the paper roll passes smoothly through the printing assembly 5.

[0033] Two sets of high-definition industrial cameras are installed on the front and rear sides of the right end of the base 2, and the two sets of high-definition industrial cameras are connected to two sets of limit frames 21.

[0034] High-definition industrial cameras are used to monitor the position of the paper roll during the real-time feeding process. Through image recognition technology, they can accurately capture the offset of the paper roll and transmit the signal to the control system. Based on the information fed back by the high-definition industrial camera, the control system automatically controls the adjustment components to fine-tune the feeding tension of the paper roll, thereby achieving precise control of the printing position of the paper roll.

[0035] The surfaces of the two sets of tension rollers 6 are covered with a rubber anti-slip layer, and the surfaces of the two sets of tension adjusting rollers 18 are mirror polished.

[0036] The rubber anti-slip layer design enhances the friction between the two sets of tension rollers 6 and the paper disc, effectively preventing the paper disc from sliding during adjustment and ensuring the accuracy and stability of the adjustment. The surfaces of the two sets of tension adjusting rollers 18 are mirror polished, which not only reduces the frictional resistance between them and the paper disc, allowing the paper disc to pass through smoothly, but also improves the overall aesthetics of the device.

[0037] Working principle: In use, the paper roll is first placed on the device. The paper roll passes between the turntable 7 and the two sets of tension adjusting rollers 18, and is flattened by the two sets of tension pressure rollers 6. The paper roll is then connected to the two sets of take-up and untake-down rollers 4 on the frame 1. The two sets of drive components 3 drive the two sets of take-up and untake-down rollers 4 to rotate and wind up the paper roll. The paper roll also moves left and right within the printing component 5. The output shaft of the first drive motor 8 drives the turntable 7 and the two sets of tension adjusting rollers 18 to rotate, and the output shaft of the second drive motor 9 drives the two sets of rotating shafts 10... Two sets of synchronous pulleys 11 and synchronous belts 12 rotate, two sets of rotating shafts 10 drive two sets of first bevel gears 13 to rotate, two sets of first bevel gears 13 drive two sets of second bevel gears 16 meshing with them to rotate, two sets of second bevel gears 16 drive two sets of first bidirectional screws 15 to rotate in turntable 7. At the same time, the left and right ends of the two sets of first bidirectional screws 15 slide in the grooves 14 of turntable 7 through threaded adjusting sliders 17, further driving two sets of tension adjusting rollers 18 to make fine adjustments to adapt to the tension changes during the paper conveying process.

[0038] 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.
