Description

Technical Field

[0001] This invention belongs to the field of winding machine technology, and in particular relates to a winding traction device for a waterproof membrane production line. Background Technology

[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, etc., to resist external rainwater and groundwater seepage. As the first step in waterproofing projects, waterproof membranes play a crucial role. During the production of waterproof membranes, the raw materials need to be rolled and stretched.

[0003] According to a search, patent document CN211254645U discloses a winding and traction device for a waterproof membrane production line, including a hopper, a support base, a first rubber roller, and a second rubber roller. The hopper has a feeding port for the waterproof membrane to pass through. The support base is vertically and parallelly arranged on both sides of the feeding port. The second rubber roller and the first rubber roller are respectively arranged parallel to the width direction of the feeding port, above and below the outer side of the feeding port. The two ends of the first rubber roller are rotatably connected to the lower end of the support base. The second rubber roller is horizontal... The second and second rubber rollers are arranged at intervals above the first rubber roller. The gap between the first and second rubber rollers forms a conveying channel for the waterproof membrane to pass through. The two ends of the second rubber roller are rotatably connected to the upper end of the support base, and the two ends of the second rubber roller are slidably disposed on the upper end of the support base in a vertical direction. The support base also includes a slider. The support base has a recessed mounting groove extending in a vertical direction in the middle. The slider is slidably embedded in the mounting groove, and the two ends of the second rubber roller are rotatably connected to the slider.

[0004] Existing coiling and traction devices for waterproof membrane production lines still have the following shortcomings: The existing equipment lacks a roll winding mechanism for waterproof membranes of different sizes and models. If the membrane is wound on a large winding roller, it is very easy for the membrane to deviate on the winding roller during unwinding, causing winding errors or irreversible deformation of the membrane surface, affecting the overall winding quality of the membrane, and also posing a certain challenge to the overall operational stability of the equipment.

[0005] When the existing device is winding up waterproof membrane, the traction rollers are too close together, making it inconvenient to insert one end of the waterproof membrane into the two traction rollers. The existing device does not offer a reasonable solution to this problem. Furthermore, since different types of waterproof membranes have different thicknesses, if the distance between the two traction rollers cannot be adjusted, it cannot wind up waterproof membranes of various thicknesses. The device as a whole can only wind up waterproof membranes of a specified thickness, which greatly limits the application scenarios of the device and significantly reduces its cost-effectiveness.

[0006] In existing devices, the drive source is often directly mounted on the traction roller shaft. When the traction roller shaft needs to be replaced or maintained, the entire shaft needs to be disassembled and replaced, which is time-consuming and labor-intensive. Furthermore, the drive source needs to be powered off during operation, which is inconvenient and increases the risk. Summary of the Invention

[0007] The purpose of this invention is to address the problems mentioned in the background art, such as the inability to wind up rolls of different widths, the inability to adjust the spacing between traction rollers, and the unreasonable driving method of the traction rollers, and to provide a winding and traction device for a waterproof roll production line that can wind up rolls of different widths, has adjustable traction roller spacing, a reasonable traction roller driving method, and is easy to maintain.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a winding and traction device for a waterproof membrane production line, comprising a base plate, a winding control plate fixedly connected to the base plate, a winding control housing provided on the winding control plate, and a membrane adapter mechanism provided inside the winding control housing; A first clamping plate and a second clamping plate are fixedly connected to the base plate. Both the first and second clamping plates have square notches. Support plates are fixedly connected to the top and bottom of the square notches. A retraction spring is fixedly connected to the end of each support plate that is close to each other. A rotating seat is fixedly connected to the end of each retraction spring that is away from the corresponding support plate. The rotating seat is slidably connected within the square notch. A control housing is provided on the first clamping plate, and a protective housing is provided on the second clamping plate. A rotating shaft is rotatably connected between the two rotating seats on the corresponding side. A traction roller shaft is coaxially fixedly connected to the rotating shaft. An adjustable roller shaft drive mechanism is provided inside the control housing.

[0009] Furthermore, the roll material adapter mechanism includes two threaded rods rotatably connected to the inner wall of the winding control housing. The two threaded rods rotate in opposite directions. Servo motors are provided at the top and bottom of the winding control housing. The output end of the servo motor passes through the winding control housing and is coaxially and fixedly connected to the threaded rod on the corresponding side.

[0010] Furthermore, a nut is threaded onto the threaded rod, a rotating shaft seat is provided on the nut, and a support arm is rotatably connected inside the rotating shaft seat. A take-up roller is slidably connected through the middle of the take-up control housing. The take-up roller passes through and is slidably connected to the take-up control plate. Two pressure plates are slidably connected to the take-up roller. A pressure buckle is threaded onto the end of the take-up roller away from the take-up control plate. A take-up circular plate is slidably connected to the take-up roller, and the take-up circular plate is located between the two pressure plates and the pressure buckle. The end of the take-up roller away from the pressure buckle is rotatably connected to the two support arms. Corresponding notches are provided on the take-up control housing for the movement positions of the two support arms and the position of the take-up roller.

[0011] Furthermore, the adjustable roller drive mechanism includes a drive plate fixedly connected to the side wall of the second clamping plate. A notch is provided in the control housing corresponding to the position of the drive plate. Two rotating shafts are coaxially fixedly connected to transmission pulleys on one side of the control housing. Two prismatic grooves are provided on the drive plate. Sliding ports are slidably connected in the two prismatic grooves. Two transmission gears are rotatably connected to one side of the sliding port. The two transmission gears mesh with each other.

[0012] Furthermore, a sliding assembly is slidably connected to the side of the drive board away from the sliding port, and a drive motor is provided on the sliding assembly.

[0013] Furthermore, the output end of the drive motor passes through the sliding port and is coaxially and fixedly connected to a transmission gear shaft on the corresponding side. The transmission gear is coaxially and fixedly connected to a drive pulley, and the drive pulley and the transmission pulley on the corresponding side are connected by a transmission belt sleeve.

[0014] Furthermore, two snap-fit ​​rotating seats are fixedly connected to the drive plate, and a lead screw is rotatably connected between the two snap-fit ​​rotating seats. A cross-shaped rotating knob is coaxially fixedly connected to one end of the lead screw, and the sliding port is threadedly connected to the lead screw.

[0015] Furthermore, the drive board has a strip-shaped opening corresponding to the sliding trajectory of the drive motor.

[0016] Compared with existing technologies, the advantages of this invention are: This invention, by setting up a roll material adaptation mechanism, allows for the disassembly of the pressure plate and the take-up plate slidably connected to the take-up roller by rotating the pressure buckle. This makes it easier to fit the waterproof roll material onto the take-up roller. For waterproof rolls of different widths, the threaded rod can be rotated by controlling the servo motor, thereby causing the two support arms to rotate at a certain angle and the take-up roller to slide, thus adapting to waterproof rolls of different widths.

[0017] This invention features an adjustable roller drive mechanism. By incorporating a retraction spring, the two traction rollers are kept at a distance from each other without any external force. Furthermore, by using transmission gears and a belt to restrict the two traction rollers, the distance between them can be adjusted while the traction rollers rotate. This allows the invention to be adapted to waterproof membranes of different thicknesses and sizes, greatly improving the compatibility of the device.

[0018] This invention, by setting two meshing transmission gears and using a transmission belt, ensures that the two traction roller shafts rotate in opposite directions. It also allows for safe and stable operation by simply removing the transmission belt when the traction roller shafts need to be disassembled for maintenance. This design also ensures the safety of the device to a certain extent. Attached Figure Description

Detailed Implementation

[0021] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0022] like Figures 1-6 As shown, a winding and traction device for a waterproof membrane production line includes: A base plate 1 is provided, and a winding control plate 2 is fixedly connected to the base plate 1. A winding control housing 3 is provided on the winding control plate 2, and a roll material adapter mechanism is provided inside the winding control housing 3. A first clamping plate 4 and a second clamping plate 5 are fixedly connected to the base plate 1. Both the first clamping plate 4 and the second clamping plate 5 have square notches. Support plates 6 are fixedly connected to the top and bottom of the square notches. A retraction spring 7 is fixedly connected to the end of the two support plates 6 that is close to each other. A rotating seat 8 is fixedly connected to the end of the retraction spring 7 that is away from the support plate 6 on the corresponding side. The rotating seat 8 is slidably connected in the square notch. A control housing 9 is provided on the first clamping plate 4, and a protective housing 10 is provided on the second clamping plate 5. A rotating shaft is rotatably connected between the two rotating seats 8 on the corresponding side. A traction roller shaft 11 is coaxially fixedly connected to the rotating shaft. An adjustable roller shaft drive mechanism is provided in the control housing 9. When the traction roller shaft 11 is not affected by other external forces, the elastic force of the retraction spring 7 is greater than the weight of the rotating seat 8, the traction roller shaft 11 and the rotating shaft. At this time, the two traction roller shafts 11 should be in a state of being far away from each other and at the farthest distance. The roll material adapter mechanism includes two threaded rods 12 rotatably connected to the inner wall of the winding control housing 3. The two threaded rods 12 rotate in opposite directions. Servo motors 13 are provided at the top and bottom of the winding control housing 3. The output end of the servo motor 13 passes through the winding control housing 3 and is coaxially and fixedly connected to the threaded rod 12 on the corresponding side. Nuts 14 are threadedly connected to the threaded rods 12. Rotating shaft seats 15 are provided on the nuts 14. A support arm 16 is rotatably connected inside the rotating shaft seats 15. A winding roller 17 is slidably connected through the middle of the winding control housing 3. The winding roller 17 passes through the winding control plate 2 and is connected to the winding control plate 2. The control plate 2 is slidably connected, and two pressure plates 18 are slidably connected to the take-up roller 17. A pressure buckle 19 is threadedly connected to the end of the take-up roller 17 away from the take-up control plate 2. A take-up plate 20 is slidably connected to the take-up roller 17, positioned between the two pressure plates 18 and the pressure buckle 19. The end of the take-up roller 17 away from the pressure buckle 19 is rotatably connected to two support arms 16. Corresponding notches are provided on the take-up control housing 3 corresponding to the movement positions of the two support arms 16 and the position of the take-up roller 17. When the two servo motors 13 are working normally, the threaded rod 12, coaxially fixedly connected to the output end of the servo motor 13... The two threaded rods 12 can rotate, with their threads running in opposite directions. When the two threaded rods 12 rotate, the nuts 14 and rotating shaft seats 15, which are threadedly connected to the threaded rods 12, can move along the axial direction of the threaded rods 12. When the two nuts 14 move closer to or further away from each other, the included angle between the support arms 16 rotatably connected to the rotating shaft seat 15 decreases or increases. At this time, the take-up roller 17, which is rotatably connected to the two support arms 16, can move towards or away from the take-up control plate 2. When the take-up roller 17 moves, the waterproof membrane material is fitted into the machine by removing the pressure buckle 19 and the pressure plate 18 threadedly connected to the take-up roller 17. After reaching the take-up roller 17, the movement of the take-up roller 17 is controlled so that the two pressure plates 18 abut against the waterproof membrane. By setting up a membrane adaptation mechanism, the pressure plates 18 and take-up plates 20 that are slidably connected to the take-up roller 17 can be disassembled by rotating the pressure buckle 19. This makes it easier to put the waterproof membrane material onto the take-up roller 17. For waterproof membranes of different widths, the threaded rod 12 can be rotated by controlling the servo motor 13, so that the two support arms 16 rotate at a certain angle and the take-up roller 17 slides, thereby adapting to waterproof membranes of different widths. The adjustable roller drive mechanism includes a drive plate 21 fixedly connected to the side wall of the second clamping plate 5. A notch is provided inside the control housing 9 corresponding to the position of the drive plate 21. Two rotating shafts are coaxially fixedly connected to transmission pulleys 22 on one side of the control housing 9. Two prismatic grooves are provided on the drive plate 21, and sliding ports 23 are slidably connected within these grooves. Two transmission gears 24 are rotatably connected to one side of the sliding ports 23, and the two transmission gears 24 mesh with each other. A sliding assembly 25 is slidably connected to the side of the drive plate 21 away from the sliding ports 23. A drive motor 26 is mounted on the sliding assembly 25, and the output end of the drive motor 26 passes through the sliding ports 23 and is coaxially fixed to the shaft of one of the transmission gears 24 on the corresponding side. The drive gear 24 is coaxially fixedly connected to a drive pulley 27. The drive pulley 27 is connected to the corresponding drive pulley 22 via a drive belt. Two locking rotating seats 28 are fixedly connected to the drive plate 21. A lead screw 29 is rotatably connected between the two locking rotating seats 28. A cross-shaped rotating knob 30 is coaxially fixedly connected to one end of the lead screw 29. The sliding port 23 is threadedly connected to the lead screw 29. A strip-shaped opening is provided on the drive plate 21 corresponding to the sliding trajectory of the drive motor 26. When the drive motor 26 is working normally, the drive gear 24, which is coaxially fixedly connected to the output end of the drive motor 26, can rotate. The two drive gears 24 mesh with each other, and at this time, the two drive gears 24 can rotate in opposite directions. The drive pulley 27, coaxially fixedly connected to the drive gear 24, can rotate. Driven by the transmission belt, the transmission pulley 22 rotates, and the traction roller shaft 11, coaxially fixedly connected to the transmission pulley 22, rotates. When it is necessary to adjust the distance between the two traction roller shafts 11, the cross-shaped rotation knob 30 can be manually rotated. The lead screw 29, coaxially fixedly connected to the cross-shaped rotation knob 30, rotates, and the sliding port 23, threadedly connected to the lead screw 29, moves the two transmission gears 24. Since the length of the transmission belt is fixed, the distance between the two traction roller shafts 11 can be adjusted. By setting an adjustable roller shaft drive mechanism and by setting a contraction spring 7, the two traction rollers... When not subjected to any external force, the shafts 11 are always in a position far apart from each other. By setting transmission gears 24 and restricting the two traction roller shafts 11 by means of belt sleeves, the distance between the traction roller shafts 11 can be adjusted while the traction roller shafts 11 are rotating. This allows it to be adapted to waterproof membranes of different thicknesses and greatly improves the compatibility of the device. By setting two transmission gears 24 to mesh with each other and by setting transmission belts, the two traction roller shafts 11 are ensured to rotate in opposite directions. At the same time, when the traction roller shafts 11 need to be disassembled for maintenance, the transmission belt can be removed for safe and stable operation. This setting also ensures the safety of the device to a certain extent.

[0023] The working principle of this invention is as follows: When the traction roller shaft 11 is not affected by other external forces, the elastic force of the contraction spring 7 is greater than the weight of the rotating seat 8, the traction roller shaft 11 and the rotating shaft. At this time, the two traction roller shafts 11 should be in a state of being far away from each other, and the distance between them should be the greatest. When the two servo motors 13 are working normally, the threaded rods 12, which are coaxially fixedly connected to the output end of the servo motors 13, can rotate. The threads of the two threaded rods 12 run in opposite directions. When the two threaded rods 12 rotate, the nuts 14 and the rotating shaft seat 15, which are threadedly connected to the threaded rods 12, can move along the axial direction of the threaded rods 12. When the two nuts 14 move closer to each other or further away, the included angle between the support arms 16 rotatably connected to the rotating shaft seat 15 decreases or increases. At this time, the take-up roller 17, which is rotatably connected to the two support arms 16, can move towards or away from one end of the take-up control plate 2. When the take-up roller 17 moves, the pressure buckle 19, which is threadedly connected to the take-up roller 17, and a... After removing the pressure plate 18 and putting the waterproof membrane material onto the take-up roller 17, the movement of the take-up roller 17 is controlled so that the two pressure plates 18 abut against the waterproof membrane. By setting up a membrane adaptation mechanism, the pressure plate 18 and the take-up plate 20 that are slidably connected to the take-up roller 17 can be disassembled by rotating the pressure buckle 19. This makes it easier to put the waterproof membrane material onto the take-up roller 17. For waterproof membranes of different widths, the threaded rod 12 can be rotated by controlling the servo motor 13, so that the two support arms 16 rotate at a certain angle and the take-up roller 17 slides, thereby adapting to waterproof membranes of different widths. When the drive motor 26 is working normally, the transmission gear 24, which is coaxially fixedly connected to the output end of the drive motor 26, will rotate. The two transmission gears 24 mesh with each other, allowing them to rotate in opposite directions. The drive pulley 27, coaxially fixedly connected to the transmission gear 24, will then rotate. Through the transmission belt, the transmission pulley 22 will rotate, causing the traction roller shaft 11, coaxially fixedly connected to the transmission pulley 22, to rotate. When it is necessary to adjust the distance between the two traction roller shafts 11, the cross-shaped rotation knob 30 can be manually rotated. The lead screw 29, coaxially fixedly connected to the cross-shaped rotation knob 30, will then rotate. The sliding port 23, threadedly connected to the lead screw 29, will then move the two transmission gears 24. Since the length of the transmission belt is fixed, the distance between the two traction roller shafts 11 will be adjusted accordingly. The distance between the two traction rollers 11 can be adjusted by setting an adjustable roller drive mechanism and a contraction spring 7 to keep them always far apart without any external force. By setting a transmission gear 24 and restricting the two traction rollers 11 by a belt, the distance between the traction rollers 11 can be adjusted while they are rotating. This allows the device to be adapted to waterproof membranes of different thicknesses, greatly improving its compatibility. By setting two transmission gears 24 to mesh with each other and by setting a transmission belt, the two traction rollers 11 can rotate in opposite directions. This also allows for safe and stable operation when the traction rollers 11 need to be disassembled for maintenance by simply removing the transmission belt. This design also ensures the safety of the device to a certain extent.
