Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to a fabric anti-deviation machine for coating machines. Background Technology

[0002] Coating machines are widely used in surface treatment processes for various materials, such as paper, plastic film, and textiles. To ensure the accurate positioning of these materials during transport and prevent lateral deviation, coating machines are usually used in conjunction with anti-deviation machines (also known as alignment machines). The function of the anti-deviation machine is to ensure the quality of subsequent processing by monitoring and correcting the positional deviation of the substrate in real time.

[0003] Existing fabric misalignment prevention machines primarily employ closed-loop control systems. Sensors (such as photoelectric or ultrasonic sensors) detect the position of the substrate edge or specific markings and feed this information back to the controller. The controller calculates the deviation between the actual and target positions based on set standards and sends adjustment commands to actuators (such as motors or guide rollers) to correct substrate misalignment. This system continuously monitors and corrects the substrate path, ensuring it always travels along the correct trajectory.

[0004] However, in practical applications, it has been found that because the guide roller in the anti-deviation machine directly contacts the substrate surface, if there is an incompletely dried coating on the substrate, the coating material may adhere to the surface of the guide roller, resulting in an uneven surface. In this case, the substrate is more likely to experience new deviation phenomena when passing through the guide roller, which not only affects the coating quality but may also cause equipment failure or increase maintenance costs. To address the above problems, this utility model proposes a fabric anti-deviation machine for coating machines. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0027] Embodiment: please refer to Figures 1 to 6 ​​The utility model discloses a cloth deviation prevention machine for coating machine, which is installed at the discharge end of the coating machine. After the base material is discharged from the coating machine, the deviation prevention machine is installed to help ensure the edge of the finished base material is neat, especially when the base material is wound to avoid deviation. The cloth deviation prevention machine comprises a rack 1, a mounting frame 2, a deflection roller 3, a driving motor 4 and a cleaning knife 5. The mounting frame 2 is rotatably arranged on the rack 1 about an axis X. The deflection roller 3 is rotatably connected to the mounting frame 2 about an axis Y perpendicular to the axis X. The driving motor 4 is used to rotate the mounting frame 2 about the axis X. The driving motor 4 is specifically a servo motor. The cleaning knife 5 is installed on the mounting frame 2 and abuts against the outer wall of the deflection roller 3.

[0028] The cloth deviation prevention machine for coating machine with the above structure can change the transmission direction of the base material by rotating the deflection roller 3 about the axis X controlled by the servo motor, so as to realize the deviation correction effect. Since the deflection roller 3 continuously contacts the base material, the surface of the deflection roller 3 may adhere to the coating material. At this time, the cleaning knife 5 can scrape the coating material adhered to the surface of the deflection roller 3, so as to realize the automatic cleaning effect of the deflection roller 3, so as to avoid the new deviation phenomenon when the base material passes through the deflection roller 3 with a dirty surface. The coating quality is improved, and the equipment failure and maintenance cost are reduced.

[0029] In the example embodiment, the cleaning knife 5 has a blade 50 consistent with the length of the deflection roller 3, and the blade 50 of the cleaning knife 5 abuts against the deflection roller 3. In this way, the blade 50 can clean the full length of the deflection roller 3, and the blade 50 is also more helpful to scrape the coating material adhered to the outer wall of the deflection roller 3.

[0030] In the example embodiment, the cleaning knife 5 is provided with a feeding channel 51, and the side of the cleaning knife 5 facing the deflection roller 3 is provided with a plurality of spray holes 52 arranged along the length direction of the cleaning knife 5. The outside of the rack 1 is provided with a liquid storage tank 6, and the feeding channel 51 is connected with the liquid storage tank 6 through a pump 7. Specifically, the liquid inlet end of the pump 7 is connected with the liquid storage tank 6 through a first pipeline 8, the liquid outlet end of the pump 7 is communicated with the feeding channel 51 of the cleaning knife 5 through a second pipeline 9, the liquid storage tank 6 is provided with a filling port, and a sealable cover 10 is arranged at the filling port. In use, cleaning liquid (water or alcohol) is added into the liquid storage tank 6, and then the cleaning liquid is pumped into the feeding channel 51 by the pump 7, and finally sprayed to the deflection roller 3 through the spray holes 52. The cleaning liquid can soften the coating material adhered to the deflection roller 3, and the cleaning effect can be improved with the cooperation of the cleaning knife 5.

[0031] In order to further improve the cleaning effect, in the present exemplary embodiment, the spray hole 52 is directly opposite the position where the blade edge 50 of the cleaning knife 5 abuts against the deflection roller 3. Such arrangement enables the cleaning liquid to be accurately sprayed at the cleaning position, ensuring the cleaning effect, while avoiding waste of the cleaning liquid.

[0032] In the present exemplary embodiment, two positioning rods 11 are fixedly arranged at the two ends of the bottom of the cleaning knife 5, the positioning rods 11 are slidably arranged through the mounting frame 2 along the radial direction of the deflection roller 3, and a spring 12 is sleeved on the positioning rod 11 between the cleaning knife 5 and the mounting frame 2. Such arrangement enables the cleaning knife 5 to be tightly attached to the deflection roller 3 by the elastic force of the spring 12, and when there is coating material on the outer wall of the deflection roller 3 that cannot be cleaned, the cleaning knife 5 can be retracted to avoid affecting the normal rotation of the deflection roller 3 around the axis Y.

[0033] In the present exemplary embodiment, one pressing roller 13 is arranged on the mounting frame 1 on the front side and the rear side of the deflection roller 3, and the pressing roller 13 is rotationally connected to the mounting frame 1. Specifically, the height of the two pressing rollers 13 is lower than the height of the deflection roller 3. Such arrangement enables the substrate to pass from below the pressing roller 13 on the front side of the deflection roller 3, then pass above the deflection roller 3, and finally pass from below the pressing roller 13 on the rear side of the deflection roller 3, which ensures that the substrate is attached to the deflection roller 3, thereby ensuring the normal guiding function of the deflection roller 3.

[0034] In the present exemplary embodiment, the fabric deviation prevention machine for the coating machine further comprises groove-type photoelectric sensors 14, and the two photoelectric sensors 14 are mounted on the two sides of the mounting frame 1 through adjusting supports 15. The adjusting support 15 comprises an adjusting round rod 150, a fixed seat 151, and a hand screw 152. The fixed seat 151 is fixed to the mounting frame 1, one end of the adjusting round rod 150 is fixed to the photoelectric sensor 14, the other end of the adjusting round rod 150 is movably penetrated through the fixed seat 151, and the hand screw 152 is threadedly connected to the fixed seat 151 along the radial direction of the adjusting round rod 150. It can be understood that the photoelectric sensor 14 needs to be used in conjunction with a controller and a driving motor 4. Specifically, the photoelectric sensor 14 is used to detect the position information of the edge of the substrate and feed back the information to the controller. The controller calculates the deviation between the actual position of the substrate and the target position according to the set standard and sends an adjusting instruction to the driving motor 4 to correct the deviation of the substrate. In addition, the adjusting support 15 can adjust the position and angle of the photoelectric sensor 14 in the width direction of the mounting frame 1, which can be suitable for deviation correction of substrates of different widths. Specifically, by loosening the hand screw 152, the adjusting round rod 150 can rotate and slide on the fixed seat 151, so that the position and angle of the photoelectric sensor 14 can be adjusted. After the adjustment is completed, the hand screw 152 is tightened to fix the position and angle of the photoelectric sensor 14.

[0035] In this exemplary embodiment, guide wheels 16 are mounted at both ends of the mounting frame 2, and a guide rail 17 is provided on the inner side of the frame 1. The guide rail 17 has an arc-shaped guide surface 170 that slides with the guide wheels 16, and the center of the circle containing the guide surface 170 is located on the axis X. With this configuration, when the mounting frame 2 rotates around the axis X, the guide wheels 16 can slide along the guide surface 170 of the guide rail 17, which can improve the rotational stability of the mounting frame 2, and thus improve the rotational stability of the steering roller 3.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
