Description

Technical Field

[0001] This utility model belongs to the technical field of paper product processing equipment, specifically relating to a high-efficiency paper winding device. Background Technology

[0002] In the paper production, processing, and subsequent handling processes, winding is a crucial step. Its quality directly affects the efficiency and effectiveness of paper storage, transportation, and subsequent secondary processing. However, paper winding devices are prone to loosening during the winding process. In traditional devices, due to factors such as fluctuations in paper tension and unstable winding roller speed, gaps easily form between paper layers, resulting in a loosely structured paper roll. Such loose paper rolls are highly susceptible to deformation and collapse during handling and stacking, affecting not only the paper's appearance quality but also potentially causing paper waste and increasing production costs for the company.

[0003] Secondly, the paper surface is easily damaged during the winding process. Some winding devices have poorly designed components that come into contact with the paper. Either the surface is not smooth enough, causing sliding friction between the component and the paper, resulting in scratches and wear on the paper surface; or the contact pressure is not properly controlled. Excessive pressure will cause wrinkles and indentations in the paper, while insufficient pressure will not ensure tight winding, seriously affecting the quality of the paper. This damage is especially unacceptable for some specialty papers that require high surface flatness. Utility Model Content

[0015] Compared with the prior art, this utility model provides a high-efficiency paper winding device, which has the following features:

[0016] Beneficial effects:

[0017] This invention features a novel pressing and anti-loosening device added parallel to and below the winding roller. The left end of this device is fixed to the outer wall of the right side of the machine housing. This device effectively prevents the paper from loosening during winding. The top of the pressing roller protrudes from the pressing support plate and, under the action of a pressure spring, consistently applies stable pressure to the paper on the winding roller, ensuring a tight fit during winding. This prevents gaps between layers due to unstable tension or external interference, ensuring a compact paper roll structure after winding and reducing the risk of loosening or deformation during transportation or subsequent processing. Furthermore, this device can adapt to thickness changes during winding; as winding progresses, the paper roll diameter gradually increases. This will push the pressure roller downwards, and the square lifting block will slide down along the lifting guide column within the return-shaped base. The pressure spring will then compress, maintaining a suitable clamping force at all times. This adaptive adjustment requires no manual intervention, ensuring the continuity and stability of pressure throughout the entire winding process. It is suitable for winding paper of different lengths and thicknesses. The device has a compact structure and is set parallel to the winding roller, so it does not affect the normal paper conveying path. Its automatic adjustment of clamping force reduces the frequency of manual monitoring and adjustment. Combined with the stable drive of the winding motor, it makes the winding process smoother, reduces downtime caused by loose paper, and indirectly improves the overall winding efficiency.

[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, for example Figure 1-5The high-efficiency paper winding device shown includes a base 2 and a device housing 5 located at the top left end of the base 2. Foot blocks 1 are provided at each of the four corners of the bottom of the base 2. This design increases the contact area with the placement surface, distributing the overall weight of the device and reducing pressure on the placement surface. Simultaneously, the friction between the foot blocks and the ground effectively improves the stability of the device during operation, preventing displacement caused by vibrations from the winding motor. A winding bearing seat 8 is located near the upper rear corner of the right end of the device housing 5. A winding roller 10 is inserted and fixed in the bearing inside the winding bearing seat 8. The winding roller 10 extends horizontally to the right. The winding bearing seat 8 cooperates with the winding roller 10 through the internal bearing. Utilizing the rolling friction characteristics of the bearing, the frictional resistance of the winding roller 10 during rotation is significantly reduced, making the rotation of the winding roller 10 smoother, reducing energy loss, and ensuring a smooth winding process. For stability, a winding motor is fixed inside the rear side of the center of the device housing 5 via a frame. Both the left end of the winding roller 10 and the left end of the motor shaft of the winding motor are equipped with transmission gears, which are connected by a transmission chain. This gear and chain combination transmission method, compared to belt drive, has the advantages of accurate transmission ratio, large power transmission, and high efficiency. It ensures that the power of the winding motor is stably transmitted to the winding roller 10, maintaining a constant speed and ensuring the uniformity of paper winding. The upper half of the front outer wall of the device housing 5 is sloped, and a controller 6 is fixed in the sloped outer wall of the front of the device housing 5. The sloped design conforms to ergonomics, allowing operators to more easily and clearly observe the display information and operation buttons on the controller 6 while standing, reducing bending or looking up during operation, improving operational convenience, and increasing work efficiency.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, a limit stop 9 is provided on the right side of the take-up bearing housing 8, and the limit stop 9 is sleeved and fixed to the outside of the take-up roller 10. A fixing screw 13 is welded to the right end of the take-up roller 10, and a take-up drum fixing nut 12 is threaded onto the outside of the fixing screw 13. After the take-up drum is sleeved onto the outside of the take-up roller 10 and the take-up drum fixing nut 12 is tightened, the take-up drum can be clamped and fixed between the take-up drum fixing nut 12 and the limit stop 9. Through the clamping action of the nut and the stop 9, the take-up drum can be quickly and firmly fixed on the take-up roller 10. The installation and disassembly process is simple and convenient, suitable for replacing take-up drums of different specifications, and meeting diverse take-up needs. A guide bearing housing 7 is provided in front of the take-up bearing housing 8, and the guide bearing housing 7 is symmetrically arranged on the front and rear sides below it. There are two additional guide bearing seats 7, and the three guide bearing seats 7 are arranged in an equilateral triangle angle. This arrangement can create stable tension in the paper during the conveying process. Through the guiding action in three directions, it can correct any possible deviation of the paper and ensure that the paper enters the take-up roller 10 in the correct posture. Guide rollers 4 are inserted and fixed in each of the three guide bearing seats 7, and the three guide rollers 4 are parallel to the take-up roller 10. The parallel arrangement of the guide rollers 4 and the take-up roller 10 can ensure that the paper is subjected to uniform force during the conveying and winding process, and avoid wrinkles or stretching deformation of the paper edges due to angular deviation. Anti-detachment blocks 3 are fixed to the right end of the three guide rollers 4, which can effectively prevent the paper from falling off the end of the guide roller 4 during the conveying process and ensure the continuity of the winding process.

[0027] like Figure 1 , Figure 4 and Figure 5As shown, a pressing and anti-loosening device 11 is arranged parallel to and below the winding roller 10. This arrangement allows the pressing and anti-loosening device 11 to act precisely on the paper during the winding process, providing stable pressure from below. It cooperates with the winding roller 10 to ensure that the paper is wound tightly. The pressing and anti-loosening device 11 includes a spiral base 14, a square lifting block 15, a pressing support plate 16, and a prism-type horizontal support 17. The spiral base 14 is vertically fixed to the outer wall of the right end of the device housing 5, and the spiral base 14 is located at the bottom of the winding bearing seat 8. This fixing method makes the entire pressing and anti-loosening device 11 firmly connected to the main body of the device. It relies on the stability of the device housing 5 to provide reliable support for itself, ensuring that it will not shake during operation. The spiral base 14 is equipped with a square lifting block 15, which can... The circular lifting block 15 moves up and down inside the U-shaped base 14. The square structure of the U-shaped base 14 plays a good guiding and limiting role for the circular lifting block, preventing the square lifting block 15 from rotating or shifting during the movement, and ensuring that it can only move in the vertical direction. A prism-type horizontal support 17 is welded to the right end of the square lifting block 15. The prism-type horizontal support 17 is parallel to the take-up roller 10. The parallel design can ensure that the pressure distribution of the subsequent pressing component on the paper on the take-up roller 10 is uniform, avoiding excessive or insufficient local pressure due to angular deviation. A pressing support plate 16 is welded to the top of the prism-type horizontal support 17. The pressing support plate 16 and the prism-type horizontal support 17 have the same thickness. The equal thickness makes the force at the connection between the two more balanced, reduces stress concentration caused by thickness difference, and extends the service life of the component.

[0028] like Figure 1 , Figure 4 and Figure 5 As shown, the clamping and anti-loosening device 11 also includes a roller groove 18 and a clamping roller 19. The upper half of the clamping support plate 16 has a downwardly recessed roller groove 18. Shaft holes are provided at the center of both ends of the roller groove 18. A clamping roller 19 is installed in the roller groove 18. Metal shafts are provided at the center of both ends of the clamping roller 19, and these metal shafts are inserted into the shaft holes. This shaft hole and metal shaft mating structure provides stable rotational support for the clamping roller 19, allowing it to rotate flexibly and clamp tightly. The pressure roller 19 can rotate clockwise and counterclockwise via a metal shaft inserted into the shaft hole. The rotational characteristics create rolling friction between the pressure roller 19 and the paper, which greatly reduces wear on the paper surface compared to sliding friction, thus protecting the paper quality. The outer wall of the pressure roller 19 is smooth and burr-free, further avoiding the risk of scratching the paper. The top of the pressure roller 19 is exposed on the upper side of the outer wall of the top of the pressure support plate 16. The exposed design allows it to directly contact and apply pressure to the paper on the take-up roller 10, achieving the core function of pressing and preventing loosening.

[0029] like Figure 1 , Figure 4 and Figure 5As shown, the compression and anti-loosening device 11 also includes a pressure spring 20, a lifting guide column 21, and a lifting guide hole 22. The lifting guide column 21 is welded and fixed at the center of the inner wall of both the upper and lower ends of the U-shaped base 14. A lifting guide hole 22 is provided inside the center of the square lifting block 15, and the square lifting block 15 is sleeved on the outside of the lifting guide column 21 through the lifting guide hole 22. The cooperation between the lifting guide column 21 and the lifting guide hole 22 provides precise guidance for the up and down movement of the square lifting block 15, ensuring its stable movement trajectory. The outer wall of the lifting guide column 21 and the inner wall of the lifting guide hole 22 are both smooth. The burr-free, smooth surface reduces the frictional resistance between the two, making the square lifting block 15 move more smoothly and reducing energy loss. A pressure spring 20 is also provided between the outer wall of the bottom end of the square lifting block 15 and the inner wall of the bottom end of the U-shaped base 14. The pressure spring 20 is sleeved on the outside of the lifting guide column 21. The elastic force of the pressure spring 20 will push the square lifting block 15 upward, thereby ensuring that the pressure roller 19 always maintains a certain pressure on the paper on the take-up roller 10. As the thickness of the paper roll increases, the pressure spring 20 will be compressed, automatically adjusting the pressure to maintain stable pressure.

[0030] 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.
