The first conveying roller and the second conveying roller are provided with guide grooves, and the guide grooves are provided with sliding and adjustable baffles. By adjusting the position of the baffle 15 according to the coating width, it is used to prevent side deviation during coating feeding. However, when side deviation occurs during coating feeding, the coating will only squeeze the inner side of the baffle, and will not reset the side-deviated coating; when drying the coating, the coating will wrinkle due to uneven temperature distribution on the coating, reducing the quality of coating drying.

Inside the drying box, a drying component for drying the coating of the DBEF fixing adhesive film is installed. At the feeding end of the drying box, a fixing frame is fixedly installed. The bottom end and the top end of the fixing frame are respectively rotatably installed with a first feeding roller and a second feeding roller. In the middle of the fixing frame, an inclination adjustment roller is installed. The inclination adjustment roller is arranged higher than the second feeding roller and can be tilted left and right for performing an inclination reset operation on the coating. At the discharging end of the drying box, motors are symmetrically installed. The output ends of the motors are fixedly installed with friction wheels. The friction wheels are inclined for frictionally pushing the coating to both sides. At the discharging end of the drying box, a flattening roller for squeezing the coating is installed. On one side of the drying box, a controller is fixedly installed.

[0006] As a further preferred of this technical solution, a mounting plate is fixedly installed in the middle of the fixing frame.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The present invention provides a technical solution: As Figures 1 to 5 shown, in this embodiment, a coating and drying device for DBEF fixing film includes a drying oven 1. A drying component for drying the coating of the DBEF fixing film is installed inside the drying oven 1. A fixing rack 2 is fixedly installed at the feeding end of the drying oven 1. A first feeding roller 3 and a second feeding roller 4 are respectively rotatably installed at the bottom end and the top end of the fixing rack 2. An inclined adjusting roller 5 is installed in the middle of the fixing rack 2. The inclined adjusting roller 5 is arranged higher than the second feeding roller 4. The inclined adjusting roller 5 can be tilted left and right for performing an inclined reset operation on the coating. Motors 6 are symmetrically installed at the discharging end of the drying oven 1. A friction wheel 7 is fixedly installed at the output end of the motor 6. The friction wheel 7 is inclined for frictionally pushing the coating to both sides. A flattening roller 8 capable of extruding the coating is installed at the discharging end of the drying oven 1. A controller 9 is fixedly installed on one side of the drying oven 1.

[0022] As Figures 1 to 5 shown, a mounting plate 10 is fixedly installed in the middle of the fixing rack 2. Electric push rods 11 are symmetrically and fixedly installed at the bottom of the mounting plate 10. The moving ends of the two electric push rods 11 pass through the mounting plate 10 and are rotatably installed with a mounting frame 12. The inclined adjusting roller 5 is rotatably installed in the middle of the mounting frame 12. Infrared sensors 13 are symmetrically and fixedly installed at both ends of the top of the mounting frame 12. The infrared sensors 13 are electrically connected to the controller 9.

[0023] The positions on both sides of the coating are monitored by the infrared sensors 13. When the coating is laterally offset, the controller 9 controls the moving end of the electric push rod 11 on the side where the coating is offset to extend, driving this side of the mounting frame 12 to rise, driving the inclined adjusting roller 5 to be inclined, and further driving the coating on this side to be in a tensioned state. Therefore, the coating will displace to the lower side, driving the coating to move to a position within the normal range.

[0024] As Figures 1 to 5As shown in the figure, fixed plates 14 are symmetrically and fixedly installed at the discharge end of the drying box 1. The motor 6 is installed inside the fixed plates 14. The friction wheel 7 is located above the coating, and is in extrusion contact with and tangent to the coating.

[0025] When the friction wheel 7 rotates, it prevents the problem that the extrusion of the coating downward by the friction wheel 7 causes the dried coating to be extruded and deformed.

[0026] As Figures 1 to 5 shown in the figure, a first support roller 15 is rotatably installed at the position directly below the friction wheel 7 between the two fixed plates 14.

[0027] When the friction wheel 7 is in frictional contact with and pulls the coating, the coating is placed between the friction wheel 7 and the first support roller 15, which is used to control the feeding direction of the coating and ensure that the friction wheel 7 can be in close frictional contact with the coating.

[0028] As Figures 1 to 5 shown in the figure, the flattening roller 8 is installed at one end of the fixed plate 14 away from the drying box 1. The flattening roller 8 is arranged below the coating. A second support roller 16 is rotatably installed at the position directly below the flattening roller 8 on the fixed plate 14.

[0029] The gravity of the flattening roller 8 restricts the coating between the flattening roller 8 and the second support roller 16, and the two sides of the coating can be flattened.

[0030] As Figures 1 to 5 shown in the figure, mounting seats 17 are symmetrically and rotatably installed at both ends of the flattening roller 8. Limit holes 18 are symmetrically opened at both ends of the mounting seats 17. Limit rods 19 are fixedly installed at the positions corresponding to the limit holes 18 on the fixed plate 14, and the limit rods 19 are slidably connected to the limit holes 18.

[0031] When the flattening roller 8 exerts gravity extrusion on the coating, the flattening roller 8 is set to be liftable to prevent permanent extrusion fold marks on the coating caused by the extrusion of the coating when it is wrinkled.

[0032] The present invention provides a coating and drying device for DBEF fixed adhesive film, and the specific working principle is as follows:

[0033] When the device is in use, the coating of the DBEF fixing film is sequentially attached to the first feeding roller 3, the second feeding roller 4, the inclined adjusting roller 5, the first supporting roller 15 and the flattening roller 8. The coating of the DBEF fixing film is dried by the drying component in the drying oven 1. The positions on both sides of the coating are monitored by the infrared sensor 13. When the coating is laterally offset, the mobile end of the electric push rod 11 on the side where the coating is offset is controlled by the controller 9 to extend, driving the elevation of this side of the mounting frame 12, which will drive the inclined adjusting roller 5 to incline, and then drive the coating on this side to be in a tension state. Therefore, the coating will displace to the lower side, driving the coating to move and driving the coating to move to a position within the normal range;

[0034] When discharging the dried coating, the motor 6 drives the friction wheel 7 to rotate. The friction wheel 7 will frictionally pull the coating on both sides, pulling the coating to restore the tension state of the coating surface. Then the coating will pass between the flattening roller 8 and the second supporting roller 16, and the tensioned coating can be gravity-extruded to keep the coating flat.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
