Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, specifically a water-based synthetic leather winding device. Background Technology

[0002] Water-based synthetic leather is a new type of polyurethane synthetic leather that uses water instead of organic solvents as the dispersion medium. It is characterized by being environmentally friendly and healthy, having excellent performance, and being widely used.

[0003] Currently, water-based synthetic leather requires a winding device for winding during production. However, commonly used winding devices are inconvenient to adjust tension and are not convenient to connect to one end of the water-based synthetic leather. For example, a water-based synthetic leather winding device disclosed in CN212981887U includes a base plate. Two first fixed columns are fixedly installed on the top left side of the base plate, and a first roller is rotatably installed between the two first fixed columns. Leather is wrapped around the first roller. Two first hydraulic rods are fixedly installed in the top middle of the base plate, and a second roller is installed between the two first hydraulic rods. A limit component, a cleaner, and a second fixed column are fixedly installed on the top right side of the base plate.

[0004] As can be seen from the above-disclosed scheme, the winding device controls the tension of the water-based synthetic leather during the winding process by extending and lowering the first hydraulic rod. However, the lifting height of the first hydraulic rod cannot be precisely controlled, making it inconvenient to adjust the appropriate tension. Furthermore, when one end of the water-based synthetic leather is fixed to the surface of the roll, it is mostly glued with double-sided adhesive, which is cumbersome and time-consuming. Moreover, the glued wrinkles are not easy to adjust, which brings inconvenience to the installation of the water-based synthetic leather and the winding device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water-based synthetic leather winding device to solve the problems of inconvenient installation of existing water-based synthetic leather and winding devices, as well as inconvenient tension adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-based synthetic leather winding device, including a winding device base, a support plate fixedly connected to the surface of the winding device base, a rotating mechanism rotatably connected to the side of the support plate, the rotating mechanism including a rotating shaft, a rotary motor fixedly connected to one end of the rotating shaft, a rotary motor fixedly connected to one end of the rotary motor and the surface of the support plate, an air shaft fixedly connected to the other end of the rotating shaft, an air nozzle provided at one end of the air shaft, and a tensioning mechanism slidably connected to the side of the support plate. Through the provided first baffle, clamping plate, second baffle, and slot, one end of the water-based synthetic leather to be wound can be firmly clamped onto the surface of the core tube, improving the ease of installation between the water-based synthetic leather end and the core tube. Furthermore, through the provided connecting arm, slider, spring, and adjusting rod, the tension force of the tensioning shaft on the wound water-based synthetic leather can be easily and quickly adjusted, making operation simple and convenient.

[0007] Preferably, the tensioning mechanism includes a tensioning shaft, one end of which is rotatably connected to a connecting arm via a bearing, one end of which is fixedly connected to a limiting seat, a rubber pad and a slider are fixedly connected to the side of the limiting seat, a central column is fixedly connected to the bottom of the slider, and a spring is sleeved on one end of the central column. The spring is located at the bottom of the groove, and the connecting arm drives the tensioning shaft to move upward by compressing the elastic force.

[0008] Preferably, the surface of the air shaft is movably connected to a first baffle, a core tube, and a second baffle. The surface of the first baffle is movably connected to a limiting ring, which is fixedly sleeved on the surface of the rotating shaft. The surface of the first baffle is fixedly connected to a clamping plate, which is made of spring steel plate and is used to fix the installation position of one end of the water-based synthetic leather on the surface of the core tube by clamping force.

[0009] Preferably, the support plate has a sliding groove on its side and a threaded hole at the top of the sliding groove. An adjusting rod is threadedly connected to the inner wall of the threaded hole. A knob is fixedly connected to one end of the adjusting rod, and a manual locking nut is threadedly connected to the surface of the adjusting rod. One end of the adjusting rod presses against the top of the slider, which can limit the height of the tensioning shaft. The higher the height of the tensioning shaft, the smaller the tension force.

[0010] Preferably, the surface of the second baffle has a slot and a sleeve hole. The inner wall of the slot is slidably connected to one end of the clamping plate, and the bottom of the clamping plate is movably connected to the surface of the core tube. The slot can restrict the position of one end of the clamping plate and improve its clamping stability.

[0011] Preferably, one end of the adjusting rod is fixedly connected to a pressing block, the side of the pressing block is slidably connected to the inner wall of the groove, and the pressing block is made of elastic rubber to prevent the adjusting rod from rotating arbitrarily.

[0012] Preferably, a retaining ring is movably connected to the surface of the tensioning shaft, and a screw is threadedly connected to the surface of the retaining ring. The retaining ring can limit the movement of both sides of the water-based synthetic leather being wound, ensuring neat winding.

[0013] Compared with the prior art, the present invention provides a water-based synthetic leather winding device, which has the following beneficial effects:

[0014] The first baffle, clamp, second baffle, and slot can firmly clamp one end of the water-based synthetic leather to be wound onto the surface of the core tube, improving the ease of installation between the water-based synthetic leather and the core tube.

[0021] 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.

[0022] This utility model provides a technical solution: a water-based synthetic leather winding device, including a winding device base 1. A support plate 11 is fixedly connected to the surface of the winding device base 1. A rotating mechanism 2 is rotatably connected to the side of the support plate 11. The rotating mechanism 2 includes a rotating shaft 21, which is rotatably connected to the support plate 11 via bearings, thereby driving an air-expanding shaft 22 to rotate. A rotary motor is fixedly connected to one end of the rotating shaft 21, and one end of the rotary motor is fixedly connected to the surface of the support plate 11. The air-expanding shaft 22 is fixedly connected to the other end of the rotating shaft 21. An air-expanding key is provided on the surface of the air-expanding shaft 22, which, after inflation, can quickly fix the installation of the first baffle 25, the core tube 24, and the second baffle 27. The position facilitates the installation of the first baffle 25, core tube 24 and second baffle 27, as well as the disassembly of the rolled water-based synthetic leather after winding. One end of the air shaft 22 is provided with an air nozzle 23. The side of the support plate 11 is slidably connected to a tensioning mechanism 3. The tensioning mechanism 3 includes a tensioning shaft 31. One end of the tensioning shaft 31 is rotatably connected to a connecting arm 34 through a bearing. One end of the connecting arm 34 is fixedly connected to a limit seat 35. The side of the limit seat 35 is fixedly connected to a rubber pad 36 and a slider 37. The bottom of the slider 37 is fixedly connected to a central column 38. One end of the central column 38 is sleeved with a spring 39. The spring 39 is located at the bottom of the slide groove 12. The compression force causes the connecting arm 34 to drive the tensioning shaft 31 to move upward.

[0023] The surface of the air shaft 22 is movably connected to a first baffle 25, a core tube 24, and a second baffle 27. A limit ring is movably connected to the surface of the first baffle 25, and the limit ring is fixedly sleeved on the surface of the rotating shaft 21. A clamping plate 26, made of spring steel, is fixedly connected to the surface of the first baffle 25. The clamping plate 26, through clamping force, fixes the installation position of the water-based synthetic leather end on the surface of the core tube 24. A sliding groove 12 is opened on the side of the support plate 11, and a threaded hole is opened at the top of the sliding groove 12. An adjusting rod 13 is threadedly connected to the inner wall of the threaded hole. A knob 14 is fixedly connected to one end of the adjusting rod 13. A manual locking nut 16 is threadedly connected to the surface of the adjusting rod 13. One end of the adjusting rod 13 presses against the top of the slider 37, which can limit the height of the tensioning shaft 31. The higher the height of the tensioning shaft 31, the smaller the tension force. The surface of the second baffle 27 has a slot 28 and a sleeve hole 29. The inner wall of the slot 28 is slidably connected to one end of the clamping plate 26. The bottom of the clamping plate 26 is movably connected to the surface of the core tube 24. The slot 28 can limit the position of one end of the clamping plate 26 and improve its clamping stability.

[0024] One end of the adjusting rod 13 is fixedly connected to a pressing block 15. The side of the pressing block 15 is slidably connected to the inner wall of the slide groove 12. The pressing block 15 is made of elastic rubber to prevent the adjusting rod 13 from rotating arbitrarily. A retaining ring 32 is movably connected to the surface of the tensioning shaft 31. A screw 33 is threadedly connected to the surface of the retaining ring 32. The retaining ring 32 can limit the two sides of the water-based synthetic leather being wound up, ensuring neat winding.

[0025] The working principle of this device is as follows: When winding water-based synthetic leather, the first baffle 25 and the core tube 24 are first sequentially fitted onto the surface of the air shaft 22. Then, one end of the water-based synthetic leather is passed through the bottom of the tensioning shaft 31. Next, the clamping plate 26 is bent so that the bottom of the clamping plate 26 forms a clamping gap with the surface of the core tube 24. Then, one end of the water-based synthetic leather is passed through the gap. Next, the clamping plate 26 is released, and the clamping plate 26 clamps one end of the water-based synthetic leather onto the surface of the core tube 24. Then, the second baffle 27 is fitted so that one end of the clamping plate 26 is inserted into the slot 28. Then, the air shaft 22 is inflated through the air nozzle 23. The air expansion shaft 22 is inflated and expanded by the air expansion key to fix the installation positions of the first baffle 25, the core tube 24 and the second baffle 27. Then the rotary motor is turned on, so that the rotary shaft 21 drives the air expansion shaft 22 to rotate, which in turn drives the core tube 24 to rotate and wind up the water-based synthetic leather. When the water-based synthetic leather is wound up, it is squeezed and tensioned downward by the tension shaft 31. When it is necessary to adjust the downward squeezing position of the tension shaft 31, it can be done by manually rotating the adjusting rod 13 counterclockwise. If the adjusting rod 13 is rotated counterclockwise, the tension shaft 31 moves upward. If the adjusting rod 13 is rotated clockwise, the tension shaft 31 moves downward.
