With special fixtures, it can also laminate products with irregular shapes such as arcs and diamonds, overcoming the shortcomings of bubbles, wrinkles, halo rings, water marks, etc. generated during manual laminating. For the laminating machine, it needs to be able to apply glue and laminate in sequence so that it has a better automation effect, and it needs to have a certain drying effect, so as to improve the stability of the lamination between the two laminated objects and prevent misalignment between the two laminated objects, and the height of the gluing roller and the laminating roller needs to be adjusted.

[0003] In response to the above technical problems, the applicant has retrieved some prior art, such as the Chinese patent with patent publication number CN210257583U, which mainly places the second object to be bonded on the object to be bonded after the glue coating, so that it can be bonded by bonding rollers and rotating rollers. However, in actual operation, it is difficult to place the second object to be bonded completely together with the object to be bonded. When the second object to be bonded is placed on the object to be bonded, the second object to be bonded often has a slight tilt with the object to be bonded. In the subsequent operation of the equipment, the tilt between the second object to be bonded and the object to be bonded becomes larger and larger, resulting in subsequent unqualified products.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that the sensor on the first synchronous roller 15 is connected to the equipment. When the sensor senses that the first synchronous roller 15 is separated from the first bonding material on the first conveyor belt 6, the equipment stops running to avoid the subsequent first bonding material and the second bonding material being unable to be accurately bonded, resulting in unqualified products.

[0026] See also Figure 3-Figure 5 The synchronous plate 13 is L-shaped, and the first synchronous roller 15 and the second synchronous roller 14 are respectively located at the vertical end and the horizontal end of the synchronous plate 13 and are rotatably connected.

[0027] Specifically, the second synchronous roller 14 and the first synchronous roller 15 abut against the second laminating material and the first laminating material respectively.

[0028] It should be noted that when the regulating cylinder 10 is started and the first synchronous roller 15 on the synchronous plate 13 contacts the first bonding material on the first conveyor belt 6, the second synchronous roller 14 on the synchronous plate 13 also contacts the second bonding material on the inclined placement surface 11. At the same time, it can ensure that both ends of the first bonding material and the second bonding material are located in the same vertical plane, preparing for the work before bonding the first bonding material and the second bonding material.

[0029] Specifically, the inclined placement surface 11 is an inclined surface, the second bonding material is placed on the inclined placement surface 11 , and the first bonding material is placed on the first conveyor belt 6 .

[0030] Specifically, the first cylinder 3 is located at the input end of the first conveyor belt 6 , the air supply box 5 is located at the output end of the first conveyor belt 6 , and the second cylinder 16 is located between the air supply box 5 and the first cylinder 3 .

[0031] The implementation principle of the utility model is as follows: when in use, first place the first laminating material on the first conveyor belt 6, start the first cylinder 3, adjust the glue roller 4 to an appropriate distance, then start the first conveyor belt 6, place the second laminating material inside the inclined placement surface 11 on the placement block 7, start the regulating cylinder 10, and the regulating cylinder 10 drives the synchronous plate 13 to move. When the sensor on the first synchronous roller 15 contacts the first laminating material on the first conveyor belt 6, the regulating cylinder 10 is closed. At this time, the second synchronous roller 14 on the synchronous plate 13 is also The second bonding material is contacted with the inclined placement surface 11, and both ends of the first bonding material and the second bonding material are ensured to be located in the same vertical plane. Then the second cylinder 16 is started, and the position of the adjustment block 8 is adjusted to make the second conveyor belt 9 on the driven roller 21 abut against the second bonding material and provide power for it, so that the second bonding material is bonded with the first bonding material through the output port of the inclined placement surface 11. The bonded second bonding material and the first bonding material are pressed together by the active roller 20. At this time, the bonding of the second bonding material and the first bonding material is completed.

[0032] It should be noted that during the operation of the equipment, when the first bonding material tilts during the bonding process, the first bonding material will separate from the sensor on the first synchronous roller 15, and the equipment will stop running to prevent the subsequent first bonding material and the second bonding material from being unable to be accurately bonded, resulting in unqualified products.

[0033] See also Figure 6-Figure 7 The adjusting block 8 is provided with a third cylinder 19, the output end of the third cylinder 19 is connected to the active roller 20, the adjusting block 8 is provided with a support rod 22, and a driven roller 21 is rotatably mounted on the support rod 22. A groove body is provided in the adjusting block 8, and a spring 17 is provided in the groove body. The spring 17 is connected to the adjusting block 8, and the adjusting block 8 is rotatably connected to the adjusting roller 18, and a second conveyor belt 9 is sleeved on the adjusting roller 18, the driven roller 21 and the active roller 20.

[0034] It should be noted that when the second laminating material is an easily stretched material, the second laminating material relies on the second conveyor belt 9 on the driven roller 21 to drag it in a single point contact, so that the first laminating material and the second laminating material are laminated together, which will stretch the second laminating material, resulting in excessive tension after laminating, thereby affecting the laminating quality. Based on this, by starting the third cylinder 19, the third cylinder 19 pushes the active roller 20 to move the active roller 20 downward. At this time, the spring 17 is compressed, and the adjustment roller 18 also moves downward, thereby adjusting the shape of the second conveyor belt 9, so that the second conveyor belt 9 between the driven roller 21 and the active roller 20 contacts the second laminating material, so that the original point contact is improved to surface contact, thereby reducing the probability of the second laminating material being stretched, so that the tension after laminating is maintained within a normal range.
