Abstract
Description
Technical Field
[0001] This utility model relates to the field of rewinding machine technology, specifically a paper-bearing device for a paper rewinding machine. Background Technology
[0002] A rewinding machine is a mechanical device used to process large-diameter flexible materials such as paper, film, and non-woven fabric into small-diameter finished products that meet specifications through processes such as slitting and winding. It is widely used in industries such as papermaking, printing, packaging, and plastics processing, and is one of the core equipment in the post-processing of flexible materials.
[0003] An investigation revealed that a Chinese utility model patent (publication number: CN218319721U) discloses a paper-bearing device for a paper rewinding machine. The device includes a frame, a paper-bearing roller mounted on the frame, racks on both sides of the frame, and a sliding plate slidably connected to the frame. A first driving device is fixedly mounted on one side of the sliding plate, and a main gear is fixedly connected to the output end of the first driving device via a shaft. A driven gear is rotatably connected to the other side of the sliding plate via a shaft. The first driving device drives the main gear to rotate, which in turn drives the driven gear to rotate via the racks. The main gear and driven gear together cause the sliding plate to slide on the frame. A second driving device drives a rotating shaft to rotate, which rewinds the paper on the paper-bearing roller. A leveling device can level any uneven paper, enabling the paper to be leveled during the rewinding process.
[0004] Although the aforementioned patent improves the efficiency of paper transmission through the arrangement of the paper receiving roller, rack, and first drive device, and enhances the flatness of paper rewinding through the cooperation of the rotating shaft and the paper receiving roller, the diameter of the paper roll gradually shrinks as the outer paper sheet of the feeding roller is continuously conveyed during the paper rewinding process. As the outer surface diameter of the paper decreases, the tension of the paper changes accordingly, making it very easy for the paper to break. This is very detrimental to improving the quality and efficiency of paper rewinding.
[0005] Therefore, this utility model provides a paper-bearing device for a paper rewinding machine to solve the above-mentioned problems. Utility Model Content

[0018] (III) Beneficial Effects

[0026] 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.
[0027] This utility model provides a paper-bearing device for a paper rewinding machine, such as... Figures 1-4As shown, a paper-bearing device for a paper rewinding machine includes a support platform 1, a support column fixedly connected to the lower bottom end of the support platform 1, and an adjustment component provided at the upper top end of the support platform 1.
[0028] The adjustment assembly includes a cylinder 2, with a rotating seat 3 fixedly sleeved at the output end of the cylinder 2. Two rotating seats 3 are rotatably connected to the inner walls of a rotating roller 4. The rotating roller 4 is hollow and has a tensioning strip 5 slidably connected to its outer wall. The inner walls of multiple tensioning strips 5 are fixedly connected by coil springs 6. The inner wall of the rotating roller 4 is rotatably connected to a bearing 7, and the inner wall of the bearing 7 is fixedly connected to a conductive strip 8.
[0029] The adjustment assembly also includes a grounding base 9 mounted on the top of the support platform 1, and the inner wall of the grounding base 9 is fixedly connected to the end of the conductive strip 8 via a conductive rod 10.
[0030] The adjustment assembly also includes a slide 11 fixedly connected to the top of the support platform 1. A bidirectional lead screw 12 is rotatably connected to the outer wall of the slide 11. A displacement seat 13 is threaded onto the outer wall of the bidirectional lead screw 12. The displacement seat 13 slides on the inner wall of the slide 11. The top of the displacement seat 13 is fixedly connected to the bottom of the cylinder 2. A material placement assembly is provided at the top of the support platform 1.
[0031] The material feeding assembly includes a lifting cylinder 14 mounted on the top of the support platform 1. An installation sleeve 15 is installed at the output end of the lifting cylinder 14, and a turntable 16 is snapped into the inner wall of the installation sleeve 15.
[0032] The inner walls of the two turntables 16 are fixedly connected with feeding rollers 17, and the outer wall of the mounting sleeve 15 is connected to the internal thread of the turntable 16 by locking bolts 18. The upper top of the support platform 1 is provided with a drive assembly.
[0033] The drive assembly includes an air pump 19 mounted on the top of the support platform 1. One of the output ends of the air pump 19 is fixedly connected to the input end of the lifting cylinder 14 via an air pipe 20, and the other output end of the air pump 19 is fixedly connected to the input end of one of the cylinders 2 via a hose 21.
[0034] Specifically, by adjusting the component settings, the stability and quality of paper rewinding can be improved through the cooperation of various parts, avoiding breakage or loosening during the rewinding process. The cylinder 2 allows for easy adjustment of the height of the roller 4, adjusting as the diameter of the outer surface of the paper on the feeding roller 17 decreases, preventing paper breakage due to excessive tension caused by a large angle difference between the paper and the roller 4. The operation of the air pump 19 allows for adjustment of the longitudinal height of the cylinder 2. An external PLC controller and other equipment can ensure that the operating frequency of the lifting cylinder 14 matches that of the cylinder 2. The input of compressed gas can also adjust the position of multiple tension bars 5, resulting in a tighter contact between them and the paper, preventing slippage. When the roller 4 conveys paper, static electricity is easily generated due to friction, which can cause the paper to adhere or stick. Therefore, the static electricity on the paper can be transferred through the cooperation of bearing 7, conductive strip 8, grounding seat 9 and conductive rod 10, thereby improving the quality of paper rewinding. Through the cooperation of bidirectional lead screw 12 and displacement seat 13, the position of the two cylinders 2 can be changed by rotating bidirectional lead screw 12, thereby adapting to paper of different widths and improving the applicability of the device. With the setting of lifting cylinder 14, mounting sleeve 15 and turntable 16, the turntable 16 can be easily disassembled for roll changing, improving the paper rewinding efficiency. After replacing the feeding roller 17, the turntable 16 can be connected by rotating locking bolt 18 to ensure its stability during operation with the internal rotating feeding roller 17. With the cooperation of air pump 19, air pipe 20 and hose 21, the operation of air pump 19 can supply compressed gas to the operation of lifting cylinder 14 and cylinder 2, ensuring the stability of their operation.
[0035] A driven platform 22 is fixedly connected to the top of the support platform 1. A driven roller 23 is rotatably connected to the inner wall of the driven platform 22. An anti-slip groove is provided on the outer wall of the driven roller 23.
[0036] Specifically, the driven stage 22 at the top of the support platform 1 facilitates the rotation of the driven roller 23, thereby facilitating the conveying of paper and ensuring its conveying efficiency.
