Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0025] like Figures 1-8 As shown, a winding device for a coating machine according to one embodiment of this application includes a frame 1. In actual use, the frame 1 can be installed on the coating machine. Two guide rollers 2 and a rotating frame 3 are rotatably arranged on the frame 1. Both the guide rollers 2 and the rotating frame 3 are horizontal, and the two guide rollers 2 are distributed vertically at intervals. A transverse frame 4 is slidably arranged on the frame 1. The transverse frame 4 slides horizontally. A horizontally oriented cylinder push rod is fixedly arranged on the frame 1. The movable end of the cylinder push rod is fixedly connected to the transverse frame 4. By extending or retracting the movable end of the cylinder push rod, the transverse frame 4 is driven to slide from the initial position to the limit position, or from the extreme position to the limit position. The limited position slides to the initial position. Two take-up rollers 5 and two tension rollers 6 are rotatably arranged on the rotating frame 3. Both the take-up rollers 5 and the tension rollers 6 are horizontal. The two take-up rollers 5 and the two tension rollers 6 are arranged in a circular array and are staggered. A take-up drum 7 is movably sleeved on the take-up roller 5. The take-up drum 7 is horizontal. The take-up roller 5 is provided with a fixing member for fixing or unfixing the take-up drum 7. A first limiting roller 8 and a second limiting roller 9 are rotatably arranged on the transverse frame 4. Both the first limiting roller 8 and the second limiting roller 9 are horizontal and are distributed vertically at intervals. A cutting member for cutting the material is provided on the transverse frame 4.
[0026] In the initial state, the transverse frame 4 is in its initial position, and neither of the two take-up drums 7 is installed. During use, one take-up drum 7 is first movably fitted onto one of the take-up rollers 5 and secured with fasteners. The rotating frame 3 is then driven to rotate 180 degrees, allowing the free end of the material to pass between the two guide rollers 2 and be fixed onto the take-up drum 7. In actual use, the surface of the take-up drum 7 is usually coated with adhesive to facilitate material fixation. Then, one of the take-up rollers 5 is driven to rotate, causing the take-up drum 7 to rotate, thereby winding the material into a roll. During the winding process, the other take-up drum 7 is movably fitted onto the other take-up roller 5 and secured with fasteners. After the previous take-up drum 7 has finished winding, the rotating frame 3 is driven to rotate 180 degrees. During this process, one of the take-up drums... The tension roller 6 rolls and overlaps with the material, then drives the transverse frame 4 to slide to its limit position. The first limit roller 8 and the second limit roller 9 roll and overlap with the material, making the material adhere to another take-up drum 7. The material is then cut by the cutting component, with the cut point located between the second limit roller 9 and the tension roller 6. Subsequently, the other take-up roller 5 is driven to rotate, causing the take-up drum 7 to rotate and wind the material into a roll. At the same time, the transverse frame 4 slides to its initial position. When the other take-up drum 7 is winding the material, the take-up drum 7 that has been wound up is released by the fixing component. The wound take-up drum 7 is then removed from the take-up roller 5, and a new take-up drum 7 is movably fitted onto the take-up roller 5 and fixed by the fixing component to complete a single operation. The operation is then repeated to achieve roll changing without stopping the machine.
[0027] In summary, this application allows for roll changing without stopping the machine when rewinding materials, which is not only convenient to operate but also ensures production efficiency, thus making it more practical.
[0028] like Figures 2-7 As shown, in some embodiments, the fixing member includes a receiving cavity 10 and a plurality of receiving grooves 11, which are all opened on the take-up roller 5 and are connected. The receiving cavity 10 and the plurality of receiving grooves 11 are all horizontal. The plurality of receiving grooves 11 are arranged in a ring array. An air inlet pipe 12, a main air bag 13 and an air outlet pipe 14 are arranged in sequence and connected in the receiving cavity 10. The air inlet pipe 12, the main air bag 13 and the air outlet pipe 14 are all horizontal and fixed in the receiving cavity 10. An exhaust valve 15 is provided on the air outlet pipe 14 and is fixed on the air outlet pipe 14. A secondary air bag 16 is provided in the receiving groove 11, which is connected to the main air bag 13 and abuts against the take-up drum 7. An air pump 17 is provided on the rotating frame 3 and is fixed on the rotating frame 3. The output end of the air pump 17 is provided with a rotary joint 18 connected to the air inlet pipe 12.
[0029] Referring to the above, in the initial state, all the auxiliary airbags 16 are in a deflated state, and the exhaust valve 15 is closed. During use, the air pump 17 works, and the gas enters the rotary joint 18, the air inlet pipe 12, the main airbag 13, and the multiple auxiliary airbags 16 in sequence. All the auxiliary airbags 16 are in an inflated state and are in contact with and overlap the inner wall of the take-up drum 7, thereby fixing the take-up drum 7. Conversely, when the exhaust valve 15 is opened, the gas is discharged from the air outlet pipe 14, and all the auxiliary airbags 16 are in a deflated state, thereby releasing the fixation of the take-up drum 7. When the take-up roller 5 rotates, the normal flow of gas can be ensured by the setting of the rotary joint 18.
[0030] like Figure 5 As shown, in some embodiments, two fixed motors 19 are provided on the rotating frame 3. The fixed motors 19 are fixed on the rotating frame 3. The output shaft of the fixed motor 19 is connected to the take-up roller 5 through a gear pair 20. The gear pair 20 includes two meshing gears, which are respectively fixed on the output shaft of the fixed motor 19 and the take-up roller 5.
[0031] Referring to the above, when in use, the fixed motor 19 is turned on, the output shaft rotates, and the take-up roller 5 is driven to rotate together through the gear pair 20.
[0032] like Figure 3 As shown, in some embodiments, the cutting component includes a slider 21 slidably disposed on the transverse frame 4, the slider 21 sliding in the horizontal direction, a screw 22 threaded through the slider 21 rotatably disposed on the transverse frame 4, the screw 22 being in the horizontal direction, and an inclined cutter 23 disposed on the slider 21, the cutter 23 being fixed on the slider 21.
[0033] Referring to the above, in the initial state, the slider 21 is located in the initial position. When in use, first, the lead screw 22 is rotated forward, and the slider 21 will slide to the limit position due to the thread action, driving the cutter 23 to move together. The cutter 23 contacts the material and cuts the material. Then, the lead screw 22 is driven to rotate in reverse, and the slider 21 will slide to the initial position due to the thread action, driving the cutter 23 to move together.
[0034] like Figure 8 As shown, in some embodiments, an adjusting frame 24 is slidably disposed on the transverse frame 4, the adjusting frame 24 slides in the circumferential direction, the second limiting roller 9 is rotatably disposed on the adjusting frame 24, and a driving member for driving the adjusting frame 24 to rotate is disposed on the transverse frame 4;
[0035] Referring to the above, in the initial state, the second limiting roller 9 is located directly below the first limiting roller 8, and the adjusting frame 24 is in the initial position. After the material is cut, the adjusting frame 24 is driven to slide to the limit position by the driving component, which drives the second limiting roller 9 to move together. The second limiting roller 9 makes the excess material adhere to the winding drum 7, thereby ensuring the subsequent winding process. Then, the adjusting frame 24 can be driven to slide to the initial position by the driving component.
[0036] like Figure 8 As shown, in some embodiments, the driving component includes a drive motor 25 mounted on the transverse frame 4, the drive motor 25 being fixed on the transverse frame 4, a toothed ring 26 being mounted on the adjusting frame 24, the toothed ring 26 being vertical and fixed on the adjusting frame 24, and a drive gear 27 being mounted on the output shaft of the drive motor 25 and meshing with the toothed ring 26, the drive gear 27 being vertical and fixed on the output shaft of the drive motor 25;
[0037] Referring to the above, when in use, the drive motor 25 is turned on and the output shaft rotates forward, driving the drive gear 27 to rotate together. Through the meshing action of the toothed ring 26 and the drive gear 27, the adjusting bracket 24 is driven to slide to the limit position. Conversely, when the output shaft of the drive motor 25 is reversed, the adjusting bracket 24 will be driven to slide to the initial position.
[0038] like Figure 2 As shown, in some embodiments, the rotating frame 3 is provided with two support members, which respectively provide rolling support for the two take-up rollers 5 or release the rolling support.
[0039] Referring to the above, in the initial state, the support does not provide rolling support for the take-up roller 5. When the take-up drum 7 is winding up the material, the support provides rolling support for the take-up roller 5 to improve the stability of use. Conversely, when the take-up drum 7 is disassembled, the support releases the rolling support for the take-up drum 7 to avoid obstructing the disassembly of the take-up drum 7.
[0040] like Figure 2 As shown, in some embodiments, the support member includes a support plate 28 slidably disposed on the rotating frame 3. The sliding direction of the support plate 28 is perpendicular to the axis of the rotating frame 3. A screw 29 threaded through the support plate 28 is rotatably disposed on the rotating frame 3. The screw 29 is distributed along the sliding direction of the support plate 28. Two support wheels 30 are rotatably disposed on the support plate 28, both of which are in rolling contact with the take-up roller 5. The two support wheels 30 are both horizontal and spaced apart.
[0041] Referring to the above, in the initial state, the support plate 28 is in the initial position, and both support wheels 30 are far away from the take-up roller 5. When in use, the screw 29 is driven to rotate forward, and the support plate 28 will slide to the limit position due to the thread action until both support wheels 30 roll and overlap with the take-up roller 5. When the take-up roller 5 rotates, the two support wheels 30 together roll and support the take-up roller 5. Conversely, the screw 29 is driven to rotate in reverse, and the support plate 28 will slide to the initial position due to the thread action, and both support wheels 30 will be far away from the take-up roller 5 to avoid obstructing the disassembly of the take-up drum 7.
[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
