[0002] Laminating machines can be divided into two categories: instant laminating machines and pre-coating laminating machines. They are special equipment used for paper, boards, and mounting films. They are pressurized by rubber rollers and heating rollers and combined to form a paper-plastic product. Laminating machines are needed when laminating paper.

[0003] After searching, a Chinese patent with publication number CN214726499U discloses a laminating device with a positioning structure, which relates to the technical field of laminating machines. The laminating device with a positioning structure includes a laminating machine body and a conveying mechanism. A laminating roller is provided in the laminating cavity of the laminating machine body. The conveying mechanism passes through the laminating cavity and is correspondingly arranged below the laminating roller; it also includes a fixed frame for fixing the conveying mechanism, and a positioning structure arranged on the left and right sides of the fixed frame; the positioning structure includes a support plate fixed to the fixed frame, a positioning plate fixed to the inner side of the support plate, a positioning rod connected to the lower end face of the positioning plate, and a positioning roller connected between the inner side of the support plate and the inner side of the positioning rod.

[0024] In this embodiment, two limit blocks 4 are fixedly connected to the front of the connecting frame 1, and the back of each limit block 4 is fixedly connected to the front of the connecting frame 1. The limit blocks 4 can protect the bearing seat 5 to prevent the bearing seat 5 from being hit. The upper surface of the second control panel 7 is fixedly connected to a holder 15, and the inner wall of the holder 15 is slidably connected to a scale 10. The bottom surface of the scale 10 is fixedly connected to the upper surface of the first control panel 9. The scale 10 can facilitate the measurement of the distance between the first control panel 9 and the second control panel 7, so that the staff can adjust it easily.

[0025] In this embodiment, a linear slide groove 19 is provided on the upper surface of each support plate 8, and a linear slider 18 is slidably connected to the inner wall of each linear slide groove 19. A stepped top plate 11 is fixedly connected to the upper surface of each linear slider 18. The stepped top plate 11 can support the first control plate 9 and the second control plate 7, so that the first control plate 9 and the second control plate 7 can be kept in position after moving upward, so as to avoid friction between the pressure roller 13 and the conveyor belt when the position of the support plate 8 is adjusted. A group of tension springs 17 are fixedly connected to the upper surface of each support plate 8. The top ends of the two groups of tension springs 17 are fixedly connected to the bottom surfaces of the first control panel 9 and the second control panel 7, respectively.

[0026] The working principle of the utility model is:

[0027] When in use, the device is installed at the feeding port of the laminating machine through the mounting holes on both sides of the connecting frame 1, so that the pressure roller 13 is located above the conveyor belt. When the step top plate 11 contacts the first control plate 9 and the second control plate 7, the tension spring 17 is in a stretched state, and the step top plate 11 is moved to the front of the first control plate 9 and the second control plate 7, so that the tension spring 17 pulls the first control plate 9 and the second control plate 7 to move downward, thereby causing the plug plate 12 to push the pressure roller 13 to move downward, and the pressure roller 13 cooperates with the conveyor belt to position the paper to prevent the paper from sliding. When the distance between the pressure rollers 13 needs to be adjusted, the positive and negative threaded rods 6 are rotated so that the positive and negative threaded rods 6 are connected to the perforated positioning block 16 through threads to control the connection block 3 to move, and the connection block 3 can drive the support plate 8 to move, thereby making the two groups of pressure rollers 13 close to each other and positioning papers of different sizes.
