Description

Technical Field

[0001] This application relates to the field of thin film processing technology, and in particular to an automatic correction friction winding device. Background Technology

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastics processing method. The manufacturing process of blown films is very similar in principle to that of blown hollow products, but it does not use molds. From the perspective of plastics processing technology classification, the forming process of blown films is usually included in extrusion. In the late 1950s, with the advent of high-density polyethylene and the development of blow molding machines, blow molding technology was widely applied. The blown film process involves: plasticizing and extruding the material to form a tube; cooling, traction, and winding.

[0003] Existing friction winding devices struggle to maintain the film in the correct position during winding, making it difficult to correct minor deviations at the film or material edges in a timely manner. This increases the risk of stretching, deformation, and damage to the film during winding, ultimately reducing winding quality. Therefore, this paper proposes an automatic correction friction winding device to address these issues. Utility Model Content

[0004] This embodiment provides an automatic correction friction winding device to solve the problem in the prior art that it is difficult to keep the film in the correct position during the winding process, so that the slight deviation of the film or material edge cannot be corrected in time, which increases the stretching, deformation and damage of the film during the winding process and reduces the winding quality.

[0005] According to one aspect of this application, an automatic correction friction winding device is provided, comprising a base, a mounting plate, a winding roller, and two correction seats. The mounting plate has two movable slots, each containing a lead screw rotatably connected to it via bearings. Two third motors are fixedly mounted on the mounting plate, their output shafts extending into the movable slots and fixedly connected to the lead screws. Movable plates are threaded onto each lead screw, and universal balls are fixedly mounted on each movable plate. Connecting seats are fixedly mounted on each correction seat, and threaded sleeves are threaded onto each connecting seat. Damping pads are provided on both the connecting seat and the threaded sleeves. The universal balls penetrate the threaded sleeves. Multiple equally spaced horizontal and vertical guide rollers are rotatably connected to the interior of each correction seat via bearings.

[0006] Furthermore, two limiting rods are fixedly installed inside each of the two movable slots, and the two movable plates are slidably connected to the two limiting rods.

[0007] Furthermore, a first fixing plate and a second fixing plate are fixedly installed on the base. A second motor is fixedly installed on the second fixing plate. The output shaft of the second motor passes through the second fixing plate and is fixedly installed on a first rotating plate. A second screw is threadedly connected to the inside of the first fixing plate. A second handwheel is fixedly installed at one end of the second screw, and the other end of the second screw is rotatably connected to the second rotating plate through a bearing.

[0008] Furthermore, multiple positioning blocks are fixedly installed on both the first and second rotating plates at equal intervals, and multiple positioning slots are opened on both sides of the winding roller at equal intervals, and the positioning blocks can be inserted into the positioning slots.

[0009] Furthermore, a first motor is fixedly installed on the base, and a threaded rod is fixedly installed through the output shaft of the first motor through the base. A fixed cylinder is threadedly connected to the threaded rod, a lifting plate is fixedly installed on the fixed cylinder, and an installation frame is fixedly installed on the lifting plate.

[0010] Furthermore, the mounting frame is internally threaded with a first screw, on which a first handwheel is fixedly mounted. The bottom end of the first handwheel is rotatably connected to a lifting frame via a bearing, and the inside of the lifting frame is rotatably connected to a pressure roller via a bearing.

[0011] Furthermore, two side plates are fixedly installed on the base, and each of the two side plates is provided with a sliding groove. Two sliders are fixedly installed on the lifting plate, and the sliders are slidably connected to the sliding groove.

[0012] Furthermore, the mounting frame is internally connected to a guide roller via a bearing.

[0013] Furthermore, the mounting frame has two guide grooves inside, and guide rods are fixedly installed inside each of the two guide grooves. Two guide blocks are fixedly installed on the lifting frame, and both guide blocks are slidably connected to the guide rods.

[0014] Furthermore, four support legs are fixedly installed at the bottom of the base.

[0015] In the above embodiments of this application, by activating the third motor, the distance between the two correction seats can be adjusted, which can control the offset of the film during the winding process, improve the winding quality, and adapt to films of different widths. This ensures that the film maintains the correct position and tension during the winding process, thereby meeting diverse production needs. Rotating the threaded sleeve facilitates the adjustment of the rotation damping, allowing the correction seat to rotate freely at multiple angles. This allows for more precise control of the correction force and direction, thereby correcting minor offsets at the edges of the film or material. This helps to meet the precise correction requirements of different materials, widths, and winding requirements, and helps to reduce wrinkles and damage to the material during the winding process, thus improving the winding quality.

[0016] By starting the first motor, the fixed cylinder is raised and lowered via the lifting plate, ensuring that the film maintains the correct position and tension before entering the winding area. This helps reduce film offset and wrinkles during winding, improving winding accuracy. It also reduces friction and wear between the film and the rollers, thereby reducing the risk of scratches and damage to the film surface. Turning the first handwheel causes the lifting roller to move closer to the film, which helps reduce stretching, deformation, and damage to the film during winding, thus improving winding quality.

[0030] Please see Figure 1-5 As shown, an automatic correction friction winding device includes a base 20, a mounting plate 14, a winding roller 19, and two correction seats 11. The mounting plate 14 has two movable slots 15, each containing a lead screw 16 rotatably connected via bearings. Two third motors 31 are fixedly mounted on the mounting plate 14, with their output shafts extending into the movable slots 15 and fixedly connected to the lead screws 16. Movable plates 10 are threaded onto each lead screw 16, allowing adjustment of the distance between the two correction seats 11. This controls the film's offset during winding, helping to reduce wrinkles and offset during winding, improving winding quality, and adapting to different widths and thicknesses. The film has a high degree of elasticity, which ensures that the film maintains the correct position and tension during the winding process, thereby meeting diverse production needs. Universal balls 34 are fixedly installed on both movable plates 10, and connecting seats 33 are fixedly installed on both correction seats 11. Threaded sleeves 32 are threadedly connected to the connecting seats 33. Damping pads are provided on both the connecting seats 33 and the threaded sleeves 32. The universal balls 34 pass through the threaded sleeves 32. Multiple horizontal guide rollers 13 and vertical guide rollers 12 are rotatably connected inside the two correction seats 11 through bearings. This reduces the frictional resistance between the rollers and the material, making the material transfer smoother and helping to improve the stability and reliability of the correction system.

[0031] Two limiting rods 17 are fixedly installed inside each of the two movable slots 15, and the two movable plates 10 are slidably connected to the two limiting rods 17 to prevent the lead screw 16 from rotating and causing the movable plate 10 to rotate.

[0032] A first fixing plate 18 and a second fixing plate 23 are fixedly installed on the base 20. A second motor 24 is fixedly installed on the second fixing plate 23. The output shaft of the second motor 24 passes through the second fixing plate 23 and a first rotating plate 25 is fixedly installed thereon. A second screw 29 is threadedly connected to the inside of the first fixing plate 18. A second handwheel 30 is fixedly installed at one end of the second screw 29, and the other end of the second screw 29 is rotatably connected to the second rotating plate 28 through a bearing.

[0033] Multiple positioning blocks 27 are fixedly installed on the first rotating plate 25 and the second rotating plate 28 at equal intervals. Multiple positioning slots 26 are provided on both sides of the take-up roller 19 at equal intervals. The positioning blocks 27 can be inserted into the positioning slots 26, which can install and remove take-up rollers of different sizes, thereby meeting diverse production needs. At the same time, it reduces the time and labor costs of replacing the take-up roller 19, helps to reduce production costs, improve overall production efficiency, and ensure the continuity and stability of the production line.

[0034] A first motor 22 is fixedly installed on the base 20. The output shaft of the first motor 22 passes through the base 20 and is fixedly installed with a threaded rod 2. A fixed cylinder 3 is threadedly connected to the threaded rod 2. A lifting plate 4 is fixedly installed on the fixed cylinder 3. An installation bracket 8 is fixedly installed on the lifting plate 4.

[0035] The mounting bracket 8 is internally threaded with a first screw 35, and a first handwheel 9 is fixedly mounted on the first screw 35. The bottom end of the first handwheel 9 is rotatably connected to a lifting frame 7 via a bearing, and a pressure roller 6 is rotatably connected to the inside of the lifting frame 7 via a bearing.

[0036] Two side plates 1 are fixedly installed on the base 20. Each of the two side plates 1 has a sliding groove 39. Two sliders 40 are fixedly installed on the lifting plate 4. The sliders 40 are slidably connected to the sliding groove 39 to prevent the threaded rod 2 from rotating and causing the fixed cylinder 3 and the lifting plate 4 to rotate.

[0037] The mounting frame 8 is internally connected to a guide roller 5 via a bearing.

[0038] The mounting frame 8 has two guide grooves 38 inside, and guide rods 36 are fixedly installed inside each of the two guide grooves 38. Two guide blocks 37 are fixedly installed on the lifting frame 7. Both guide blocks 37 are slidably connected to the guide rods 36 to prevent the first screw 35 from rotating and causing the lifting frame 7 to rotate.

[0039] Four support legs 21 are fixedly installed at the bottom of the base 20.

[0040] When this application is used, all electrical components mentioned in this application are connected to an external power supply and control switch. When the first motor 22 is started, the output shaft of the first motor 22 rotates, which drives the threaded rod 2 to rotate. With the cooperation of the slide groove 39 and the slider 40, the fixed cylinder 3 drives the mounting frame 8 to rise and fall through the lifting plate 4. This can ensure that the film maintains the correct position and tension before entering the winding area, which helps to reduce the film's offset and wrinkles during the winding process, improve the winding accuracy, and at the same time reduce the friction and wear between the film and the roller, thereby reducing the risk of scratches and damage to the film surface.

[0041] Rotating the first handwheel 9 drives the first screw 35 to rotate. With the cooperation of the guide rod 36 and the guide block 37, the lifting frame 7 moves the pressure roller 6 closer to the film, which helps to reduce the stretching, deformation and damage of the film during the winding process, thereby improving the winding quality. By making the multiple positioning slots 26 on the right side of the winding roller 19 insert into the multiple positioning blocks 27 on the first rotating plate 25, and then rotating the second handwheel 30, the second handwheel 30 drives the second screw 29 to rotate and move at the same time, so that the second rotating plate 28 moves closer to the winding roller 19 until the multiple positioning blocks 27 are all inserted into the positioning slots 26, winding rollers 19 of different sizes can be installed and removed, thereby meeting diverse production needs. At the same time, it reduces the time and labor costs of replacing the winding roller 19, which helps to reduce production costs, improve overall production efficiency, and ensure the continuity and stability of the production line.

[0042] When the third motor 31 is started, the output shaft of the third motor 31 rotates, driving the lead screw 16 to rotate. With the cooperation of the two limit rods 17, the movable plate 10 moves along the surface of the lead screw 16, which can adjust the distance between the two correction seats 11. This can control the offset of the film during the winding process, which helps to reduce wrinkles and offset of the film during winding, improve the winding quality, and adapt to films of different widths and thicknesses. It can ensure that the film always maintains the correct position and tension during the winding process, thereby meeting diverse production needs.

[0043] Rotating the threaded sleeve 32 causes it to move up and down simultaneously, bringing the damping pad and the universal ball 34 closer together or further apart. This increases or decreases the friction between the damping pad and the universal ball 34, allowing for easy adjustment of the rotational damping. This enables the alignment seat 11 to rotate freely at multiple angles, allowing for more precise control of the alignment force and direction. This corrects minute deviations at the edges of films or materials, helping to meet precise alignment requirements for different materials, widths, and winding processes. It also helps reduce wrinkles and damage to materials during winding, improving winding quality. By incorporating multiple horizontal guide rollers 13 and vertical guide rollers 12 inside the alignment seat 11, frictional resistance between the alignment seat and the material is reduced, resulting in smoother material transport and improved stability and reliability of the alignment system.

[0044] The advantages of this application are:

[0045] 1. By activating the third motor 31, the distance between the two correction seats 11 can be adjusted, which can control the offset of the film during the winding process. This helps to reduce wrinkles and offsets of the film during winding, improves winding quality, and can adapt to films of different widths and thicknesses. It can ensure that the film maintains the correct position and tension during winding, thereby meeting diverse production needs. Rotating the threaded sleeve 32 makes it easy to adjust the damping of the rotation, allowing the correction seat 11 to rotate freely at multiple angles. This allows for more precise control of the correction force and direction, thereby correcting minor offsets at the edges of the film or material. This helps to meet the precise correction requirements of different materials, widths, and winding requirements, and helps to reduce wrinkles and damage to the material during winding, improving winding quality.

[0046] 2. By starting the first motor 22, the output shaft of the first motor 22 rotates, driving the threaded rod 2 to rotate. With the cooperation of the slide groove 39 and the slider 40, the fixed cylinder 3 moves up and down through the lifting plate 4 and the mounting frame 8. This ensures that the film maintains the correct position and tension before entering the winding area, which helps to reduce the film's offset and wrinkles during the winding process, improves winding accuracy, and reduces friction and wear between the film and the roller, thereby reducing the risk of scratches and damage to the film surface. Rotating the first handwheel 9 causes the lifting frame 7 to drive the pressure roller 6 closer to the film, which helps to reduce the stretching, deformation and damage of the film during the winding process, thereby improving the winding quality.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
