Description

Technical Field

[0001] This utility model relates to the technical field of plastic film winding equipment, and in particular to a plastic film winding equipment with tension adjustment function. Background Technology

[0002] A plastic film winding machine with tension adjustment function is a device specifically designed to maintain a constant tension during the plastic film winding process. This device can not only effectively adjust the tension during the winding process, but also reduce damage to the plastic film when cleaning it, thereby improving the practicality and production efficiency of the equipment. A plastic film winding machine with tension adjustment function is a highly efficient and precise device suitable for winding various plastic films. Through its unique tension adjustment mechanism and cleaning protection design, this equipment not only improves production efficiency but also significantly reduces production costs, demonstrating good market prospects and application value.

[0003] According to the patent application published on the Internet, a plastic film winding device with tension adjustment function (authorization announcement number: CN222181303 U) is described as follows: "This utility model relates to the field of plastic film winding technology and discloses a plastic film winding device with tension adjustment function, including a base. Multiple mounting plates are provided on the upper left and right sides of the base. A unwinding roller is rotatably arranged between two mounting plates on the right side, and a winding roller is rotatably arranged between two mounting plates on the left side. A vertical plate is provided on the upper rear side of the base. A rotating rod is rotatably arranged on the upper front end of the vertical plate. A guide mechanism is provided on the front of the rotating rod. A gear is provided through the rear side of the rotating rod and on the vertical plate. A connecting block is provided on the lower rear end of the vertical plate, and an adjustment mechanism that works with the gear is provided on the connecting block."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this invention has several drawbacks. When the operator grips the handle, the threaded rod rotates. This rotation, through the cooperation of the guide groove and guide block, moves the toothed plate. The toothed plate, via gears, drives the rotating rod, which in turn rotates the disc and the first guide roller. Adjusting the position of the first guide roller changes the winding tension on the plastic film. However, the guide roller cannot be positioned according to the width of the plastic film, potentially leading to uneven tension distribution during winding. This uneven tension can cause the plastic film to slip or misalign during winding, resulting in unstable winding and increasing the risk of equipment failure. Therefore, an improved plastic film winding device with tension adjustment function is needed to solve these problems. Utility Model Content

[0006] To overcome the problem that when the guide roller of the plastic film winding equipment with tension adjustment function cannot be limited according to the width of the plastic film, it may lead to uneven tension distribution of the plastic film during the winding process, thus affecting the winding quality of the plastic film. Due to uneven tension, the plastic film may slip or misalign during the winding process, resulting in unstable winding and increasing the risk of equipment failure.

[0007] The technical solution of this utility model is as follows: a plastic film winding device with tension adjustment function, including a device base, a rotating disk and a cleaning component. A first fixed support plate is fixedly connected to the top of the device base, a connecting fixed seat is fixedly connected to the top of the device base, and a second fixed support plate is fixedly connected to the top of the device base. The cleaning component is disposed inside the connecting fixed seat. A rotating disk is rotatably connected inside the connecting fixed seat. A second guide roller is rotatably connected to the inner side of the rotating disk. A support mounting plate is fixedly connected to the outer side of the second guide roller. An electric telescopic rod is fixedly connected to the inner side of the support mounting plate. A limit ring is fixedly connected to the inner side of the electric telescopic rod. The limit ring is slidably connected to the outer side of the second guide roller.

[0008] Preferably, there are two connecting fixing seats, and the two connecting fixing seats are symmetrically fixedly connected to the top of the device base.

[0009] Preferably, the limiting ring has a groove at the corresponding position of the second guide roller, and the limiting ring is slidably connected to the outside of the second guide roller through the groove.

[0010] Preferably, a first rotating shaft is rotatably connected inside the connecting base, a rotating handle is fixedly connected to the right side of the first rotating shaft, a first gear is fixedly connected to the outside of the first rotating shaft, a second rotating shaft is rotatably connected inside the connecting base, a second gear is fixedly connected to the outside of the second rotating shaft, the second gear is meshed with the outside of the first gear, and the second rotating shaft is fixedly connected inside the rotating disk.

[0011] Preferably, the connecting fixing seat has a groove at the corresponding position of the second rotating shaft, and the second rotating shaft is rotatably connected inside the connecting fixing seat.

[0012] Preferably, the cleaning assembly includes a drive motor, a drive motor is fixedly connected to the left side of the first fixed support plate, a take-up roller is fixedly connected to the output end of the drive motor, the take-up roller rotates to the inside of the first fixed support plate, a first guide roller is rotatably connected to the inside of the connecting fixed seat, an unwinding roller is rotatably connected to the inside of the second fixed support plate, a support connecting column is fixedly connected to the inside of the connecting fixed seat, a sliding connecting block is slidably connected to the outside of the support connecting column, a return spring is fixedly connected between the sliding connecting block and the connecting fixed seat, a first cleaning roller is rotatably connected to the inside of the sliding connecting block, and a second cleaning roller is rotatably connected to the inside of the connecting fixed seat.

[0013] Preferably, the connecting fixing seat has a groove at the corresponding position of the sliding connecting block, and the sliding connecting block slides inside the groove.

[0014] The beneficial effects of this utility model are as follows: Compared with plastic film winding equipment that cannot limit the tension of the plastic film during transmission, this device uses an electric telescopic rod on a support mounting plate to push a limiting ring to slide outside the second guide roller. The limiting ring is adjusted and limited according to the width of the plastic film being guided on the second guide roller, allowing it to limit the transmission according to the width of the plastic film. This ensures that the tension of the plastic film is evenly distributed during winding, making the winding more stable and guaranteeing the safety of the equipment. It effectively prevents uneven tension distribution of the plastic film and unstable winding caused by the guide roller's inability to limit the width of the plastic film during use, which increases the risk of equipment failure.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5This utility model provides an embodiment: a plastic film winding device with tension adjustment function, including a device base 1, a rotating disk 906, and a cleaning component. A first fixed support plate 2 is fixedly connected to the top of the device base 1, a connecting fixed seat 3 is fixedly connected to the top of the device base 1, and a second fixed support plate 4 is fixedly connected to the top of the device base 1. The cleaning component is disposed inside the connecting fixed seat 3. The rotating disk 906 is rotatably connected inside the connecting fixed seat 3. A second guide roller 907 is rotatably connected to the inner side of the rotating disk 906. A support mounting plate 908 is fixedly connected to the outer side of the second guide roller 907. An electric telescopic rod 909 is fixedly connected to the inner side of the support mounting plate 908. A limit ring 910 is fixedly connected to the inner side of the electric telescopic rod 909. The limit ring 910 is slidably connected to the outer side of the second guide roller 907. The device base 1 provides support for the device. The electric telescopic rod 909 on the support mounting plate 908 pushes the limiting ring 910 to slide outside the second guide roller 907. The limiting ring 910 is adjusted and limited according to the width of the plastic film that drives and guides the second guide roller 907. Two connecting fixing seats 3 are provided and symmetrically fixed to the top of the device base 1. The two connecting fixing seats 3 provide support for the second guide roller 907. The limiting ring 910 has a groove at the corresponding position of the second guide roller 907. The limiting ring 910 is slidably connected to the outside of the second guide roller 907 through the groove. The groove at the corresponding position of the second guide roller 907 inside the limiting ring 910 limits the limiting ring 910 when it slides outside the second guide roller 907.

[0023] Please see Figure 2 - Figure 3In this embodiment, a first rotating shaft 901 is rotatably connected inside the connecting base 3. A rotating handle 902 is fixedly connected to the right side of the first rotating shaft 901. A first gear 903 is fixedly connected to the outside of the first rotating shaft 901. A second rotating shaft 904 is rotatably connected inside the connecting base 3. A second gear 905 is fixedly connected to the outside of the second rotating shaft 904. The second gear 905 meshes with the outside of the first gear 903. The second rotating shaft 904 is fixedly connected inside the rotating disk 906. When the user rotates the rotating handle 902 by hand, the first gear 903 outside the first rotating shaft 901 is driven. The second rotating shaft 904 rotates inside the connecting base 3, which in turn drives the second rotating shaft 904 to rotate inside the connecting base 3. The rotation of the second rotating shaft 904 drives the second guide roller 907 on the rotating disk 906 to rotate inside the connecting base 3, thus adjusting the tension of the plastic film. The connecting base 3 has a groove at the corresponding position of the second rotating shaft 904. The second rotating shaft 904 is rotatably connected inside the connecting base 3. The groove at the corresponding position of the second rotating shaft 904 inside the connecting base 3 makes the sliding of the second rotating shaft 904 more stable.

[0024] Please see Figure 4 - Figure 5 In this embodiment, the cleaning component includes a drive motor 801. The drive motor 801 is fixedly connected to the left side of the first fixed support plate 2. A take-up roller 802 is fixedly connected to the output end of the drive motor 801. The take-up roller 802 rotates to the inside of the first fixed support plate 2. A first guide roller 803 is rotatably connected to the inside of the connecting fixed base 3. An unwind roller 804 is rotatably connected to the inside of the second fixed support plate 4. A support connecting column 805 is fixedly connected to the inside of the connecting fixed base 3. A sliding connecting block 806 is slidably connected to the outside of the support connecting column 805. A return spring 807 is fixedly connected between the sliding connecting block 806 and the connecting fixed base 3. The inner side of the 6 is rotatably connected to a first cleaning roller 808, and the inner side of the connecting fixing seat 3 is rotatably connected to a second cleaning roller 809. When the plastic film passes between the second cleaning roller 809 and the first cleaning roller 808, the return spring 807 will push the first cleaning roller 808 on the sliding connecting block 806 to push the plastic film to contact the second cleaning roller 809. During transmission, the surface of the plastic film is cleaned. The connecting fixing seat 3 is provided with a sliding groove at the corresponding position of the sliding connecting block 806. The sliding connecting block 806 slides inside the sliding groove. By opening the sliding groove inside the connecting fixing seat 3 at the position corresponding to the sliding connecting block 806, the sliding connecting block 806 is limited when sliding inside the sliding groove.

[0025] During operation, the plastic film on the unwinding roller 804 passes sequentially between the second cleaning roller 809 and the first cleaning roller 808, through the first guide roller 803, and is fixed onto the take-up roller 802 via the second guide roller 907. The take-up roller 802 is driven to rotate by the drive motor 801, pulling the plastic film to wind it up. The electric telescopic rod 909 on the support mounting plate 908 pushes the limiting ring 910 to slide outside the second guide roller 907. The limiting ring 910 is adjusted according to the width of the plastic film guided on the second guide roller 907 to limit its movement. The user manually rotates the rotating handle 902, driving the first rotating shaft... The first gear 903 and the second gear 905 on the outside of 901 mesh and rotate. The rotation of the second gear 905 drives the second rotating shaft 904 to rotate inside the connecting fixed base 3. The rotation of the second rotating shaft 904 drives the second guide roller 907 on the rotating disk 906 to rotate inside the connecting fixed base 3, which plays a role in tension adjustment of the plastic film. When cleaning, when the plastic film passes between the second cleaning roller 809 and the first cleaning roller 808, the return spring 807 pushes the first cleaning roller 808 on the sliding connecting block 806 to push the plastic film to contact the second cleaning roller 809, thus cleaning the surface of the plastic film during transmission.

[0026] Through the above steps, the electric telescopic rod 909 on the support mounting plate 908 pushes the limiting ring 910 to slide outside the second guide roller 907. The limiting ring 910 is adjusted and limited according to the width of the plastic film guided by the second guide roller 907. This solves the problem that when the plastic film winding equipment with tension adjustment function is used, the guide roller cannot be limited according to the width of the plastic film, which may lead to uneven tension distribution of the plastic film during the winding process, thus affecting the winding quality of the plastic film. Due to uneven tension, the plastic film may slip or misalign during the winding process, resulting in unstable winding and increasing the risk of equipment failure.
