Description

Technical Field

[0001] This utility model relates to the field of stretch film winding technology, specifically a high-viscosity stretch film winding device with adaptive tension winding. Background Technology

[0002] In the modern packaging industry, high-adhesion stretch film is widely used for bundling, securing and protecting goods due to its good tensile strength, self-adhesion and puncture resistance. As a key step in the production and processing of stretch film, the quality of winding directly affects the subsequent performance and packaging effect of the stretch film.

[0003] Traditional high-viscosity stretch film winding devices typically employ fixed tension control during the winding process. This method cannot automatically adjust the tension based on changes in the winding diameter. As the winding diameter gradually increases from the empty roll diameter to the full roll diameter during winding, if the tension remains constant, the actual tension acting on the film material will rise sharply with the diameter increase. This leads to large gaps between film layers during the initial winding stage, causing the finished roll to become loose, misaligned, or even unravel during transport. Later, excessive tension causes overstretching and wrinkles in the stretch film, severely impacting the winding quality. Therefore, an adaptive tension winding device for high-viscosity stretch film is needed to address the problems existing in current technology. Utility Model Content

[0004] The purpose of this invention is to provide a high-viscosity winding device for adaptive tension winding to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-viscosity winding device for adaptive tension winding, comprising:

[0006] A take-up roller for mounting a roll of winding film;

[0007] A winding thickness sensing component is disposed at the edge of the area above the winding roller, and the winding thickness sensing component is used to detect the winding thickness of the stretch film.

[0008] An elasticity adaptation mechanism is slidably connected to the winding thickness sensing component, and the elasticity adaptation mechanism is used to adapt to the height change of the winding thickness sensing component;

[0009] An automatic gear shifting mechanism is fixed to one end of an elastic adaptation mechanism and is used to switch the torque gear of a servo motor.

[0010] Preferably, a lifting support is provided on one side of the take-up roller, one end of the take-up roller is rotatably connected to the surface of the lifting support, a servo motor is fixed on one side of the lifting support, and the output end of the servo motor passes through the bearing seat on the lifting support and is fixed to one end of the take-up roller.

[0011] Preferably, a motor torque control mechanism is embedded in one side surface of the raised support. The motor torque control mechanism includes a motor torque controller, which has a circuit board and a motor torque control module inside. A first gear button is provided on one side surface of the motor torque controller, a second gear button is provided on one side surface of the motor torque controller above the first gear button, and a third gear button is provided on one side surface of the motor torque controller above the second gear button.

[0012] Preferably, the elastic adaptation mechanism includes a spring sleeve, which is fixed to one side surface of the raised support. A lifting slide plate is slidably connected inside the spring sleeve, and a telescopic slide arm is slidably passed through inside the spring sleeve. The lifting slide plate is sleeved and fixed outside the telescopic slide arm.

[0013] Preferably, a spring is fixed between the lifting slide plate and the inner bottom wall of the spring sleeve, and the spring is sleeved on the outside of the telescopic sliding arm.

[0014] Preferably, the winding thickness sensing component includes a rotating frame and a compression guide wheel. The rotating frame is fixed to one end of the telescopic sliding arm, and the compression guide wheel is rotatably connected to the rotating frame.

[0015] Preferably, the automatic shifting mechanism includes a lifting seat, which is fixed to the other end of the telescopic sliding arm. A compression roller is rotatably connected inside the lifting seat, and a rotating groove adapted to the rotation of the compression roller is opened inside the lifting seat. A buffer rubber sleeve is fixedly fitted on the surface of the compression roller.

[0016] Preferably, one end of the take-up roller is fixed with an adjusting stud, and a side baffle is threaded onto the surface of the adjusting stud.

[0017] This invention provides a high-viscosity winding device for adaptive tension winding, which has the following advantages compared with the prior art:

[0018] Through the designed elastic adaptation mechanism and winding thickness sensing component, the elastic force generated by the spring ensures that the pressure guide roller always maintains a moderate contact pressure with the stretch film. This accurately senses changes in winding thickness without damaging the stretch film due to excessive pressure. Furthermore, the pressure guide roller moderately squeezes the edges of the stretch film, effectively correcting any deviation that may occur during winding. This results in neat edges on the wound roll, preventing unevenness and ensuring the accuracy of automatic winding thickness detection and the quality of the stretch film.

[0019] By incorporating an elastic adaptation mechanism, a winding thickness sensing component, an automatic shifting mechanism, and a motor torque control mechanism, the servo motor operates at a lower torque during the initial winding stage when the wrapping film is thinner. This prevents excessive tension caused by excessive torque, which could lead to overstretching of the wrapping film. As the winding thickness increases, the servo motor automatically switches to a suitable higher torque setting, ensuring stable tension throughout the winding process. This results in a tight and neat wrapping film, effectively preventing loosening and wrinkling during winding. This significantly improves the winding quality and efficiency of the wrapping film, meeting the needs of different packaging scenarios for high-viscosity wrapping film winding. This method of monitoring tension and automatically shifting gears reduces manual intervention, lowers labor costs, and increases winding efficiency and automation, making the wrapping film winding process more efficient and stable.

Detailed Implementation

[0028] 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.

[0029] Please see Figure 1-7 This utility model provides a high-viscosity winding device for adaptive tension winding, comprising:

[0030] Take-up roller 2, which is used to mount the roll of winding film;

[0031] The winding thickness sensing component 9 is located at the edge of the area above the winding roller 2. The winding thickness sensing component 9 is used to detect the winding thickness of the wrapping film. The winding thickness sensing component 9 includes a rotating frame 12 and a pressing guide wheel 13. The rotating frame 12 is fixed to one end of the telescopic sliding arm 11, and the pressing guide wheel 13 is rotatably connected to the rotating frame 12.

[0032] The elastic force generated by the spring 15 ensures that the coiling guide roller 13 maintains appropriate contact pressure with the stretch film, guaranteeing accurate sensing of changes in winding thickness while preventing damage to the stretch film due to excessive pressure. Meanwhile...

[0033] The elasticity adaptation mechanism 6 is slidably connected to the winding thickness sensing component 9. The elasticity adaptation mechanism 6 is used to adapt to the height change of the winding thickness sensing component 9. The elasticity adaptation mechanism 6 includes a spring sleeve 10, which is fixed to one side surface of the lifting support 1. A lifting slide plate 14 is slidably connected inside the spring sleeve 10. A telescopic slide arm 11 is slidably passed through inside the spring sleeve 10. The lifting slide plate 14 is sleeved and fixed to the outside of the telescopic slide arm 11. A spring 15 is fixed between the lifting slide plate 14 and the inner bottom wall of the spring sleeve 10. The spring 15 is sleeved to the outside of the telescopic slide arm 11. The winding thickness sensing component 9 located at the edge of the area above the winding roller 2 starts to work, and its pressure guide wheel 13 keeps in contact with the wrapping film. As the stretch film continues to roll up, its thickness gradually increases. The pressure guide wheel 13 is subjected to an upward force, which drives the telescopic sliding arm 11 to slide upward inside the spring sleeve 10. During this process, the lifting slide plate 14, which is sleeved on the outside of the telescopic sliding arm 11, moves synchronously, compressing the spring 15 between the lifting slide plate 14 and the inner bottom wall of the spring sleeve 10. The pressure guide wheel 13 moderately squeezes the edge of the stretch film to correct any deviation that may occur during winding, ensuring that the edge of the rolled roll is neat after winding.

[0034] An automatic gear shifting mechanism 7 is fixed to one end of the elastic adaptation mechanism 6. The automatic gear shifting mechanism 7 is used to switch the torque gear of the servo motor 5. A motor torque control mechanism 8 is embedded in one side surface of the lifting support 1. The motor torque control mechanism 8 includes a motor torque controller 20. The motor torque controller 20 has a circuit board and a motor torque control module inside. A first gear button 21 is provided on one side surface of the motor torque controller 20. A second gear button 22 is provided on one side surface of the motor torque controller 20 above the first gear button 21. A third gear button 23 is provided on one side surface of the motor torque controller 20 above the second gear button 22.

[0035] As the telescopic sliding arm 11 rises, the lifting seat 16 in the automatic shifting mechanism 7 fixed at its other end rises accordingly, and the extrusion roller 18 inside the lifting seat 16 also rises synchronously. When the extrusion roller 18 rises to a certain height, it contacts and extrudes the gear button in the motor torque controller 20. The motor torque controller 20 is equipped with a first gear button 21, a second gear button 22, and a third gear button 23. The extrusion roller 18 triggers the corresponding gear button in sequence according to the different winding thickness. After the button is triggered, it transmits the signal to the motor torque control module. After receiving the signal, the module adjusts the output current, voltage, and other control signals according to the preset gear parameters, so that the servo motor 5 switches to the corresponding set torque operation, realizing the automatic switching of the torque gear of the servo motor 5. In the early stage of winding, the servo motor 5 operates at a lower torque to prevent the wrapping film from being overstretched due to excessive torque. As the winding thickness increases, the servo motor 5 automatically switches to a suitable higher torque gear to ensure that the tension remains stable throughout the winding process, so that the wrapping film is wound tightly and neatly, avoiding problems such as looseness and wrinkles.

[0036] It is worth noting that a lifting support 1 is provided on one side of the take-up roller 2, and one end of the take-up roller 2 is rotatably connected to the surface of the lifting support 1. A servo motor 5 is fixed on one side of the lifting support 1, and the output end of the servo motor 5 passes through the bearing seat on the lifting support 1 and is fixed to one end of the take-up roller 2.

[0037] It is worth noting that the automatic shifting mechanism 7 includes a lifting seat 16, which is fixed to the other end of the telescopic sliding arm 11. The lifting seat 16 is rotatably connected to a compression roller 18. The lifting seat 16 has a rotating groove 17 that is adapted to the rotation of the compression roller 18. A buffer rubber sleeve 19 is fixedly fitted on the surface of the compression roller 18.

[0038] It is worth noting that one end of the take-up roller 2 is fixed with an adjusting stud 3, and the surface of the adjusting stud 3 is threaded with a side baffle 4.

[0039] The purpose of this solution is to provide a high-viscosity stretch film winding device with adaptive tension winding, which has the following working process: Before winding, the roll for winding the stretch film is installed on the winding roller 2. The movement of the roll can be restricted by the adjusting stud 3 at one end of the winding roller 2 and the side baffle 4. The servo motor 5 is fixed on one side of the lifting support 1, and its output end passes through the bearing seat and is connected to the winding roller 2 to provide power for the winding process.

[0040] During the winding process, the winding diameter gradually increases from the initial empty roll diameter to the full roll diameter. If the tension remains constant, the actual tension acting on the membrane material will increase sharply as the diameter increases. The physical principle is: tension = torque / winding radius. This change must be counteracted by "adaptive adjustment".

[0041] When winding begins, the winding roller 2 rotates under the drive of the servo motor 5 to wind up the wrapping film. Since there is less material on the winding roller 2 at the beginning, that is, the diameter of the material on the winding roller 2 is small, the automatic shifting mechanism 7 is in the first gear position button 21 on the motor torque controller 20. In this gear position, the speed and torque of the servo motor 5 are at their maximum to keep the tension at the standard value of the initial winding, so as to prevent the problem of large gaps between film layers during winding, easy loosening and deviation of the finished roll, or even unwinding during transportation.

[0042] During the winding process, the winding thickness sensing component 9, located at the edge of the area above the winding roller 2, monitors the thickness of the film. The pressure guide roller 13 contacts the stretch film. As the stretch film is continuously wound, its thickness gradually increases, and the pressure guide roller 13 is subjected to an upward force, which in turn drives the telescopic sliding arm 11 to slide upward within the spring sleeve 10. During this process, the lifting slide plate 14 is sleeved on the outside of the telescopic sliding arm 11, and the spring 15 between it and the inner bottom wall of the spring sleeve 10 is compressed. The elastic force generated by the spring 15 can keep the pressure guide roller 13 in contact with the stretch film at an appropriate level. This can accurately sense changes in winding thickness without damaging the stretch film due to excessive pressure. In addition, the pressure guide roller 13 moderately squeezes the edge of the stretch film, effectively correcting the problem of the stretch film going off track during winding, making the edge of the wound roll neat and avoiding unevenness. This ensures the accuracy of automatic detection of winding thickness and the quality of the stretch film.

[0043] As the telescopic sliding arm 11 rises, the lifting seat 16 in the automatic shifting mechanism 7 fixed at its other end also rises. The lifting seat 16 has a rotatably connected pressing roller 18 inside, and its surface is covered with a buffer sleeve 19. When the pressing roller 18 rises to a certain height, it contacts and presses against the gear button in the motor torque controller 20. The motor torque controller 20 is equipped with a first gear button 21, a second gear button 22, and a third gear button 23. Depending on the winding thickness, the pressing roller 18 will sequentially trigger different gear buttons, transmitting signals to the motor torque control module. After receiving the signals, the module adjusts the output current, voltage, and other control signals according to the preset gear parameters, causing the servo motor 5 to operate at the set... The torque operation mode enables automatic switching of the torque level of the servo motor 5. In the initial stage of winding, when the wrapping film is thin, the servo motor 5 operates at a lower torque to avoid excessive tension and overstretching of the wrapping film due to excessive torque. As the winding thickness increases, the servo motor 5 automatically switches to a suitable higher torque level to ensure stable tension throughout the winding process. This results in a tight and neat winding of the wrapping film, effectively preventing problems such as looseness and wrinkles during winding. This significantly improves the winding quality and efficiency of the wrapping film, meeting the needs of different packaging scenarios for winding high-viscosity wrapping film. This method of monitoring tension and automatically switching gears reduces manual intervention, lowers labor costs, improves winding efficiency and automation, and makes the wrapping film winding process more efficient and stable.
