Abstract
Description
Technical Field
[0001] This utility model relates to the field of film roll transport technology, and in particular to a guiding and correction device for film roll transport. Background Technology
[0002] Film rolls are widely used in many fields such as packaging, electronics, optics, and construction. In the packaging industry, films are used for packaging food, medicine, and daily necessities to protect products, extend shelf life, and enhance product display. In the electronics field, optical films and electronic insulating films are indispensable components of electronic products. In the construction industry, building insulation films and decorative films provide buildings with better performance and aesthetics.
[0003] During the unwinding or rewinding process of films and other roll materials, offset may occur during the transmission of the conveyor rollers. During rewinding, the offset of the film will result in uneven edges of the final film roll, which may cause damage to the film at the ends of the roll during transfer and storage. If transmission offset occurs in the printing, slitting and other processing steps, it will affect the accuracy of subsequent slitting and printing, leading to printing deformation and misalignment, incorrect product specifications, increased scrap rate, waste of production materials, increased production costs, and disruption to normal production operations.
[0004] Therefore, how to develop a guiding and correction device for thin film roll transportation is a technical problem that urgently needs to be solved in the industry. Utility Model Content
[0005] The main purpose of this invention is to provide a guiding and correction device for film roll transport, which aims to solve the problem that deviation during film transport can affect normal winding, printing or slitting operations.
[0006] This utility model proposes a guiding and correction device for film roll conveying, including a mounting plate. A second guide roller, a third guide roller and a fourth guide roller are sequentially arranged from one end of the mounting plate to the other end. A detection component is arranged after the fourth guide roller. A correction mechanism that adjusts the angle and direction according to the detection result of the detection component is arranged between the second guide roller and the third guide roller.
[0007] The correction mechanism includes a rotating frame rotatably mounted on a mounting plate via a bracket. A first correction roller and a second correction roller are rotatably mounted at both ends of the rotating frame. The first correction roller and the second correction roller form an angle with the transmission direction and their inclination directions are opposite. When the first correction roller or the second correction roller rotates to the top, it adheres to the film body and guides the film body to achieve correction.
[0008] Preferably, vertical plates are provided on both sides of the mounting plate, and the surface of the vertical plates is provided with a plurality of mounting holes.
[0009] Preferably, two first leveling rollers and second leveling rollers for leveling the film body are rotatably and obliquely disposed between the third guide roller and the fourth guide roller.
[0010] Preferably, the mounting plate is provided with a mounting frame on the top, and the first leveling roller and the second leveling roller are rotatably mounted on the mounting frame. The mounting frame is provided with second motors on both sides at a transverse angle, and the output shaft of each second motor is fixedly connected to one end of the first leveling roller and the second leveling roller.
[0011] Preferably, the rotating frame includes a rotating shaft, a first support plate, and a second support plate. The rotating shaft is rotatably disposed in the middle of the support. The first support plate and the second support plate are respectively fixedly connected to the two ends of the rotating shaft. The first support plate and the second support plate are arranged in a cross configuration, so the first correction roller and the second correction roller are rotatably disposed between the top and bottom of the first support plate and the second support plate, respectively.
[0012] Preferably, a first motor for driving the rotating frame to rotate is arranged laterally on one side of the bracket.
[0013] This invention uses a control system to calculate the offset and direction of the film roll based on signals transmitted from the detection component. The system then controls the rotation of a rotating shaft, which in turn rotates the first and second support plates. This causes the positions of the first and second alignment rollers to change. When the film body tilts to the right, the first alignment roller rotates upwards to bring the film roll into contact with it, gradually adjusting it to the correct transmission position. When the film body tilts to the left, the second alignment roller rotates upwards to bring the film roll into contact with it. This effectively prevents the roll from shifting during transmission, improves the transmission effect and efficiency, and ensures the neatness and aesthetics of the rolled material after winding.

[0022] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0023] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0024] Reference Figure 1-7 This invention proposes an embodiment of a guiding and correcting device for transporting film rolls, comprising a mounting plate 1, wherein a second guide roller 5, a third guide roller 6 and a fourth guide roller 7 are sequentially arranged from one end of the mounting plate 1 to the other end, a detection component 10 is arranged after the fourth guide roller 7, and a correction mechanism is arranged between the second guide roller 5 and the third guide roller 6 to adjust the angle and direction according to the detection result of the detection component 10.
[0025] The mounting plate 1 is provided with a first guide roller 4 and a fifth guide roller 8 at one end and the other end, respectively. The film body 17 passes from below the first guide roller 4 to above the second guide roller 5, then passes above the third guide roller 6, the height of the third guide roller 6 being lower than the height of the second guide roller 5, then passes below the fourth guide roller 7, and finally passes above the fifth guide roller 8.
[0026] All the guide rollers are rotating, and can be driven by a drive motor to rotate the multiple guide rollers.
[0027] The detection component 10 is typically equipped with high-precision position sensors, such as photoelectric sensors, ultrasonic sensors, or CCD vision systems. These sensors are installed at critical locations along the film transport path, such as the unwinding end, the rewinding end, or during transport. The sensors monitor the position of the film edge or specific marking lines in real time by emitting light beams, ultrasonic waves, or using image capture technology. When the film shifts, the sensors can detect this change and convert the position deviation information into an electrical signal.
[0028] The correction mechanism includes a rotating frame mounted on the mounting plate 1. A first correction roller 14 and a second correction roller 15 are rotatably mounted at both ends of the rotating frame. The first correction roller 14 and the second correction roller 15 form an angle with the transmission direction and their inclination directions are opposite. When the first correction roller 14 or the second correction roller 15 rotates to the top, it adheres to the film body 17 and guides the film body 17 to achieve correction.
[0029] A first motor 16 for driving the rotating frame to rotate is arranged laterally on one side of the bracket 9.
[0030] The first motor 16 is a DC motor.
[0031] exist Figure 1 From the perspective shown, in the initial state, the rotating frame is in a horizontal position, and both the first and second straightening rollers 14 and 15 are in standby positions. When the first motor 16 rotates clockwise, it drives the rotating frame to rotate clockwise, rotating the first straightening roller 14 to the working position directly above. When rotating counterclockwise, it drives the rotating frame to rotate counterclockwise, rotating the first straightening roller 14 back to the standby state. Figure 1 The state shown;
[0032] When the first motor 16 reverses, it drives the rotating frame to rotate clockwise, which rotates the second correction roller 15 to the top and puts it in the working position. When it rotates back, it drives the rotating frame to rotate counterclockwise, which rotates the second correction roller 15 to the standby state.
[0033] Please refer to Figure 4 and Figure 5 The tilting directions of the first correction roller 14 and the second correction roller 15 form an angle with the standard transmission direction of the film body 17, which can be 15-30°. When the first correction roller 14 and the second correction roller 15 are at their highest points, they are in a horizontal state. The left end of the first correction roller 14 is in front and the right end is behind, forming an tilted state. The left end of the first correction roller 14 is in front and the right end is behind, forming an tilted state. The first correction roller 14 can correct the film body 17 that is tilted to the right, so that it tilts to the left while being transmitted. The second correction roller 15 can correct the film body 17 that is tilted to the left, so that it tilts to the right while being transmitted, thereby reducing the tilt angle and bringing the film body 17 back to the standard transmission direction.
[0034] When no correction is required, the rotating frame rotates to a lateral position, and neither the first correction roller 14 nor the second correction roller 15 contacts the film body 17. When correction is required using the first correction roller 14 or the second correction roller 15, the first motor 16 drives the rotating frame to rotate forward or backward by 90°, and drives the first correction roller 14 or the second correction roller 15 to rotate directly upward for correction. After correction is completed, the first motor 16 drives the rotating frame to rotate backward or forward by 90° and resets it to the standby state.
[0035] The device is also equipped with a processor (not shown in the figure), which transmits signals to the detection component 10 and the first motor 16 in the correction mechanism via a line. It can receive and process the data detected by the detection component 10, determine the deflection direction of the film body 17, and then send a control signal to the first motor 16 to control the first motor 16 to rotate forward or backward, thereby rotating the first correction roller 14 or the second correction roller 15 to the top. The upper edge slightly lifts the film body 17, thus making close contact with the film body 17. Under the transmission of the film body 17, the first correction roller 14 or the second correction roller 15 is driven to rotate by the film body 17, thereby guiding the film body 17 in an inclined posture in the horizontal plane, so that the deflected film body 17 moves in the direction of reducing deflection.
[0036] When the detection component 10 detects that the film body 17 is in the correct position, it sends a signal to the first motor 16. The first motor 16 drives the rotating frame to rotate, thereby driving the first correction roller 14 or the second correction roller 15 to rotate downwards and disengage from the film body 17, and no longer perform correction.
[0037] Considering that when the detection component 10 detects that the film body 17 is in the correct position, the film body 17 at that position has already moved a certain distance backward from the correction mechanism. The film body 17 between that position and the correction mechanism has also been corrected to one side by the correction mechanism at a certain angle. At this time, if the detection component 10 detects that the film body 17 is in the correct position, it will control the correction mechanism to disengage after overcorrection, causing the subsequent film body 17 to deflect in the opposite direction. Therefore, in actual use, the setting can be made according to the transmission speed of the film body 17 and the distance between the correction mechanism and the detection component 10. When the detection component 10 detects that the film body 17 has a certain deflection angle, at this time point, the film body 17 at the contact position with the correction mechanism is exactly in the correct position. At this time, the correction mechanism is controlled to disengage to avoid overcorrection.
[0038] Please refer to Figure 2 , 67. The rotating frame includes a rotating shaft 13, a first support plate 11 and a second support plate 12. The rotating shaft 13 is rotatably disposed in the middle of the bracket 9. The first support plate 11 and the second support plate 12 are respectively fixedly connected to the two ends of the rotating shaft 13. The first support plate 11 and the second support plate 12 are arranged in a cross pattern. Therefore, the first correction roller 14 and the second correction roller 15 are rotatably disposed between the top and bottom of the first support plate 11 and the second support plate 12, respectively.
[0039] Furthermore, vertical plates 2 are respectively provided on both sides of the mounting plate 1, and a plurality of mounting holes 3 are provided on the surface of the vertical plates 2.
[0040] The device can be installed in different locations as needed using the vertical plate 2.
[0041] Furthermore, two first flattening rollers 18 and second flattening rollers 20 are rotatably and obliquely disposed between the third guide roller 6 and the fourth guide roller 7 for flattening the film body 17.
[0042] During the transport of the film body 17, due to various reasons (such as uneven film winding, tension changes after correction, etc. during transport), the film body 17 may develop unevenness such as wrinkles and arching. This will not only affect the transport stability of the film, but may also lead to quality problems in subsequent processing (such as printing, coating, etc.). The first leveling roller 18 and the second leveling roller 20 are rotatably and inclined between the third guide roller 6 and the fourth guide roller 7 in order to solve this problem.
[0043] Furthermore, the top of the mounting plate 1 is provided with a mounting frame, and the first leveling roller 18 and the second leveling roller 20 are rotatably mounted on the mounting frame. The mounting frame is provided with second motors 19 on both sides at a transverse angle, and the output shaft of each second motor 19 is fixedly connected to one end of the first leveling roller 18 and the second leveling roller 20.
[0044] The output shafts of the two second motors 19 rotate in opposite directions, ensuring that the rotation direction of the first flattening roller 18 and the second flattening roller 20 is outward, which can flatten the film body 17 and solve the problem of wrinkles.
[0045] By starting the second motor 19, the first leveling roller 18 and the second leveling roller 20 are driven to rotate, thereby smoothing out the wrinkles on the surface of the film body 17.
[0046] During operation, when the detection component 10 detects the offset of the film body 17, the control system calculates the offset amount and offset direction based on the offset signal, and then controls the first motor 16 to rotate. The output shaft of the first motor 16 is fixedly connected to one end of the rotating shaft 13. A reducer is provided on its output shaft, which can precisely control the rotation angle of the rotating shaft 13. The rotating shaft 13 drives the first support plate 11 and the second support plate 12 to rotate together, thereby changing the position of the first correction roller 14 and the second correction roller 15. When the film body 17 tilts to the right, the first correction roller 14 rotates to the top so that the film body 17 is in contact with the first correction roller 14, gradually adjusting to the correct transmission position. When the film body 17 tilts to the left, the second correction roller 15 rotates to the top so that the film body 17 is in contact with the second correction roller 15, thereby realizing the correction of the transmission direction of the film roll.

Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
