Abstract
Description
Technical Field
[0001] This utility model relates to the field of coated paper technology, specifically a wrinkle removal device for coated paper processing. Background Technology
[0002] Coated paper is a paper material that achieves bonding, sealing, and protection by mechanically or manually applying adhesive to its surface. During processing, coated paper requires the use of a wrinkle-removing device to prevent wrinkles from forming on the finished paper surface.
[0003] Existing adhesive paper wrinkling removal devices have a complex structure and unreasonable design. During heating and pressing, they typically only heat the side containing the film, which is then pressed onto the paper surface. However, the side containing the paper is not heated, leading to uneven heating and excessive temperature differences between the film and paper, causing wrinkles. Furthermore, misalignment between the paper and film during transport can also result in incomplete bonding, wrinkles, and a reduced yield. Therefore, the inventors have improved the structure of the adhesive paper wrinkling removal device. Utility Model Content

[0013] 1. This utility model provides a wrinkle removal device for coated paper processing. The wrinkle removal device includes a frame and a wrinkle removal mechanism set on the frame. A calibration mechanism is set on the wrinkle removal mechanism. The overall structure is simple and reasonably designed. The wrinkle removal mechanism includes a first conveying roller, a second conveying roller set below the first conveying roller, and a center roller set below the second conveying roller.

The main calibration blocks can limit the paper, and the slave calibration blocks can limit the film, so that the two are always aligned during the transportation process, avoiding wrinkles caused by incomplete connection between the two. Since the positions of the main calibration blocks and slave calibration blocks are adjustable, it can adapt to the processing of coated paper of different widths, thus increasing the scope of application.

[0025] Please see Figure 1 One embodiment of this utility model is a wrinkle removal device for coated paper processing. The wrinkle removal device for coated paper processing includes a frame 1 and a wrinkle removal mechanism 2 disposed on the frame 1. A calibration mechanism 3 is disposed on the wrinkle removal mechanism 2.
[0026] Please see Figures 2 to 3 The frame 1 includes a processing table 11, on which two symmetrically arranged side panels 12 are fixed. The wrinkle removal mechanism 2 includes a first conveying roller 21, a second conveying roller 22 disposed below the first conveying roller 21, and a center roller 23 disposed below the second conveying roller 22. A lowering roller 24 is disposed below the center roller 23, and a receiving roller 25 is disposed below the lowering roller 24. The first conveying roller 21, the second conveying roller 22, the center roller 23, the lowering roller 24, and the receiving roller 25 are also present. The first conveying roller 21, the second conveying roller 22, and the receiving roller 25 are all horizontally arranged between the two side panels 12. The structure and working principle of the first conveying roller 21, the second conveying roller 22, and the receiving roller 25 are all existing technologies and will not be described in detail here. A roll 26 is sleeved on the receiving roller 25. The roll 26 is in the shape of a ring and rotates with the rotation of the receiving roller 25, so that the film and paper are bonded together after being heated and pressed. The calibration mechanism 3 includes a motor 31, which is fixed on one of the side panels 12 and is horizontally arranged.
[0027] Please see Figure 4The calibration mechanism 3 also includes a lead screw 32 connected to the output end of the motor 31. A first guide rod 33 is provided above the lead screw 32, and the threads at both ends of the lead screw 32 have opposite directions. A set of main calibration blocks 34 are provided on the lead screw 32. The set of main calibration blocks 34 are slidably disposed on the first guide rod 33 and are disposed on one side of the second conveying roller 22. A second guide rod 35 is provided above the set of main calibration blocks 34. A set of secondary calibration blocks 36 are slidably disposed on the second guide rod 35. The set of secondary calibration blocks 36 are disposed on one side of the first conveying roller 21 and are located above the main calibration blocks 34. In this embodiment, there are two main calibration blocks 34, and the two main calibration blocks 34 are symmetrical about the two ends of the first guide rod 33. Similarly, there are also two secondary calibration blocks 36, and they are symmetrical about the two ends of the second guide rod 35. The main calibration block 34 is positioned above the two slave calibration blocks 36, and is connected to the slave calibration blocks 36 via a vertically arranged connecting rod 37. Therefore, the main calibration block 34 can drive the slave calibration blocks 36 to move together. A first arc surface 341 is formed at the end of the main calibration block 34 near the second conveying roller 22, and a second arc surface 361 is formed at the end of the slave calibration block 36 near the first conveying roller 21. The first arc surface 341 is close to the second conveying roller 22, and the second arc surface 361 is close to the first conveying roller 21. The main calibration block 34 can limit the movement range of the paper, and the slave calibration block 36 can limit the movement range of the film. The lead screw 32, the first guide rod 33, and the second guide rod 35 are all horizontally arranged. Both ends of the lead screw 32 are rotatably connected to the mounting base 38. The first guide rod 33 and the second guide rod 35 are fixed between the two side panels 12. Both ends of the mounting base 38 are fixed to the two side panels 12 respectively.
[0028] Please see Figures 5 to 6 The center roller 23 includes an inner heating roller 231 and a first heating ring 232 fixed inside the inner heating roller 231. A first electric heating tube 233 is installed inside the first heating ring 232. The lowering roller 24 includes an outer heating roller 241 and a second heating ring 242 fixed inside the outer heating roller 241. A second electric heating tube 243 is installed inside the second heating ring 242.
[0029] Working principle: Please refer to the following again. Figures 1 to 6In this invention, after determining the width values of the film and paper, the drive motor 31 drives the lead screw 32 to move, causing the two main calibration blocks 34 to move closer together. This confines the paper between the two main calibration blocks 34 during movement. Simultaneously, the two secondary calibration blocks 36 also move closer together, confining the film between the two secondary calibration blocks 36 during movement. This ensures that the two are always aligned during transport, preventing wrinkles caused by incomplete connection. Since the positions of the main calibration blocks 34 and secondary calibration blocks 36 are adjustable, it adapts to the processing of coated paper of different widths. The film is input from the first conveying roller 21, causing... The film undergoes heat treatment via the center roller 23 and the lower roller 24. The paper is fed in from the second conveyor roller 22 and undergoes heat treatment after passing through the center roller 23 and the lower roller 24. At the same time, the paper is pressed together with the film. After the two are pressed together, they are stored on the roll 26. The film is heated by the first electric heating tube 233 and the paper is heated by the second electric heating tube 243. During heating, the ambient temperature is controlled between 18℃ and 22℃ and the humidity is between 60% and 70%. The surface temperature of the inner heating roller 231 and the outer heating roller 241 is controlled between 50℃ and 60℃, thereby avoiding the paper from being exposed to a high temperature and high humidity environment for a long time and causing wrinkles.
[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
