[0002] Laminating machines can be divided into two categories: instant laminating machines and pre-coating laminating machines. It is a special equipment for paper, board and film mounting. After being pressurized by rubber rollers and heating rollers, they are combined together to form a paper-plastic product.

[0003] When laminating paper products, it is usually done continuously, that is, the paper is rolled on a paper roll in advance, and then the paper is fed into the laminating machine at a uniform speed for lamination. In order to ensure the continuous, efficient and uninterrupted operation of the laminating machine, a large amount of paper is usually rolled into the paper roll, which makes the diameter, length and weight of the paper roll very large, making it difficult to load and unload directly by hand, and usually requires the assistance of lifting equipment, and the operation process is also relatively cumbersome. It is necessary to remove the used paper roll first, and then rotate the shaft hole of the paper roll and insert it after the shaft is rotated. The whole process seems simple, but under the premise of large size and heavy weight of the paper roll, each step is very troublesome, and it has considerable labor intensity requirements for workers. Therefore, it is necessary to design a paper roll installation device with high efficiency and low labor intensity. Utility Model Content

[0027] Example

[0028] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 8 As shown, the paper roll installation structure of the laminating machine of this embodiment includes a horizontally arranged bottom plate 11, and a pair of support components respectively arranged at the two ends of the bottom plate 11; the support component includes a vertically arranged support plate 12, a through hole arranged at the upper end of the support plate 12, a sleeve 13 horizontally arranged at the through hole, a top block 21 slidably arranged in the sleeve 13, and a driving device for driving the top block 21 to move along the axial direction of the sleeve 13; the driving device is rotatably connected to the top block 21; the end of the top block 21 away from the driving device is conical. Specifically, when in use, the paper roll 14 is transported between the pair of support components (such as the attached) by a transportation device such as a cart. Figure 2 The top block 21 is pushed toward the paper roll 14 by the driving device in the support assembly and inserted into the central axis hole 15 of the paper roll 14 (as shown in the attached figure). Figure 3 As shown in the figure, since the end of the top block 21 is conical, the top block 21 can be well inserted into the paper roll 14, and as the top block 21 goes deeper, the top block 21 can directly position the paper roll 14, so that when placing the paper roll 14, it is not necessary to completely align the paper roll 14 with the top block 21, and it can also be installed normally. In this way, the paper roll 14 can be slightly lower than the height of the top block 21, and the paper roll 14 can be lifted by the top block 21, and then the cart can be taken out from under the paper roll 14. The reverse operation can be performed for disassembly. In this way, for paper rolls 14 with large diameters, long lengths, and heavy weights, the installation and disassembly are very efficient and convenient, and the labor intensity of workers can be reduced to a certain extent. It should be noted that the paper roll 14 needs to rotate during use, so the drive device needs to be rotatably connected to the top block 21 to prevent the drive device from affecting the normal rotation of the paper roll 14.

[0029] The top block 21 in this embodiment is a hollow structure, and a first slide plate 24 is slidably arranged inside the top block 21, a spring 25 is arranged between the first slide plate 24 and the end of the top block 21 away from the driving device, and a second slide plate 27 is arranged at the end of the first slide plate 24 away from the spring 25; the second slide plate 27 is connected to the driving device, and the first slide plate 24 and the second slide plate 27 are connected by magnetic attraction. A plane bearing 28 is arranged between the first slide plate 24 and the second slide plate 27, and the plane bearing 28 is made of ceramic material. Specifically, the driving device pushes the top block 21 to move through the second slide plate 27, the first slide plate 24 and the spring 25. The plane bearing 28 made of ceramic material is arranged between the first slide plate 24 and the second slide plate 27, which can not only make the sliding of the first slide plate 24 and the second slide plate 27 smoother, but also can keep a certain magnetic attraction between the first slide plate 24 and the second slide plate 27, so that the second slide plate 27 can not only push the first slide plate 24 to move, but also pull the first slide plate 24 to move.

[0030] The top block 21 in this embodiment is provided with a plurality of sliding holes 22 at one end away from the driving device, and a slider 23 is slidingly provided in the sliding hole 22, and one end of the slider 23 provided in the top block 21 is fixedly connected to the first slide plate 24. A groove 26 is provided at one end of the inner wall of the top block 21 close to the spring 25, and the end of the spring 25 is provided in the groove 26. Specifically, the slider 23 can abut against the inner wall of the shaft hole 15 of the paper roll 14, thereby better supporting the paper roll 14. The driving device first drives the end of the top block 21 to be inserted into the shaft hole 15 of the paper roll 14, and then compresses the spring 25 after the position is fixed, and pushes the slider 23 out of the sliding hole 22 through the first slide plate 24, and enters the shaft hole 15 of the paper roll 14 (as shown in the attached figure). Figure 4 As shown), a better fixing and supporting effect of the paper roll 14 is achieved.

[0031] The driving device in this embodiment includes a horizontally arranged hydraulic cylinder 29 and a bracket 210 for connecting the hydraulic cylinder 29 and the support plate 12 ; the output end of the hydraulic cylinder 29 is fixedly connected to the second slide plate 27 .

[0032] In summary, the paper roll installation structure of the laminating machine of the present embodiment is used to transport the paper roll 14 between a pair of supporting components by a transport device such as a cart, and the top block 21 is pushed toward the paper roll 14 by the driving device in the supporting component, and inserted into the central axis hole 15 of the paper roll 14. Since the end of the top block 21 is conical, the top block 21 can be well inserted into the paper roll 14, and as the top block 21 goes deeper, the top block 21 can directly position the paper roll 14, so that when placing the paper roll 14, it is not necessary to completely align the paper roll 14 with the top block 21, and it can also be installed normally. In this way, the paper roll 14 can be slightly lower than the height of the top block 21, and the paper roll 14 can be lifted by the top block 21, and then the cart can be taken out from under the paper roll 14. The reverse operation can be performed when disassembling. In this way, for paper rolls 14 with large diameters, large lengths, and large weights, the installation and disassembly are very efficient and convenient, which can reduce the labor intensity of workers to a certain extent.
