[0003] When the existing high-efficiency automatic laminating mechanism is in use, it is difficult to keep the laminating roller in a stable dynamic balance at all times, which increases the possibility of uneven force and damage to the film, reduces the integrity of the laminating film, and easily causes wrinkles in the laminating film or local loose lamination, making it difficult for the film to fit the plastic surface, and at the same time increases the load of the laminating roller motor; when the existing high-efficiency automatic laminating mechanism is in use, it is difficult to adjust according to different film width requirements, and usually it is necessary to replace laminating rollers of different sizes, which reduces the versatility and flexibility of the equipment, resulting in the film not maintaining the correct position and tension during the winding process, resulting in uneven laminating, wrinkles and other problems, and reducing the quality and stability of the laminating film; when the existing high-efficiency automatic laminating mechanism is in use, it is difficult to adjust the tension of the film, resulting in the film being easily damaged or deformed due to improper tension, increasing the waste of the film, and at the same time it is difficult to flexibly adapt to the laminating requirements of different materials;

The following is an explanation of the embodiments of the present invention based on its overall structure.

[0031] Embodiment 1:

[0032] See also Figure 1~Figure 3 , an efficient automatic laminating mechanism of a double-sided laminating machine of the present invention comprises a conveying member 1, the left end and the top left end of the conveying member 1 are both slidably connected with a first mounting plate 2, a rotating shaft 3 is rotatably connected inside the first mounting plate 2, a counterweight mechanism 4 is rotatably connected to the outer wall of the rotating shaft 3, two groups of rotating shafts 3 are provided, and laminating rollers 5 are fixedly connected inside the two groups of rotating shafts 3, two groups of tensioning mechanisms 6 are fixedly connected to the left side of the front end of the conveying member 1, a third mounting plate 7 is fixedly connected to the right end of the back of the conveying member 1, a preheating mechanism 8 is fixedly connected to the center of the top rear end of the third mounting plate 7, a cooling mechanism 9 is fixedly connected to the top right rear end of the third mounting plate 7, and a cutting member 10 is fixedly connected to the center of the top of the conveying member 1;

[0033] The counterweight mechanism 4 includes a mounting ring 41 , the outer wall of the rotating shaft 3 is rotatably connected with the mounting ring 41 , and the right end at the bottom of the mounting ring 41 is fixedly connected with a mounting rod 42 , so that the mounting ring 41 is convenient for mounting and fixing the mounting rod 42 .

[0034] The bottom of the mounting rod 42 is magnetically attracted to the outer wall of the first electromagnetic block 43 , and a placement shell 44 is fixedly connected to the bottom of the first electromagnetic block 43 . The placement shell 44 is convenient for placing the counterweight 45 .

[0035] A counterweight block 45 is provided in the placement shell 44, and two sets of film width adjustment mechanisms 46 are slidably connected to the outer wall of the coating roller 5. An electric spring 47 is fixedly connected to the left end of the bottom of the mounting ring 41, and resistance strain gauges 48 are glued and connected to the spring wire axis of the electric spring 47 in the ±45° direction. The resistance strain gauges 48 facilitate the calculation of the length change of the electric spring 47.

[0036] The bottom of the electric spring 47 is fixedly connected to the left end of the top of the placement shell 44, the first electromagnetic block 43 is electrically connected to the external current output device, and the first electromagnetic block 43 passes through the bottom of the installation rod 42 and is slidably connected to the inside thereof.

[0037] The working principle of a high-efficiency automatic laminating mechanism of a double-sided laminating machine based on the first embodiment is:

[0038] First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation;

[0039] Second, the staff places the plastic part on the third mounting plate 7, and preheats the plastic part through the preheating mechanism 8, and then controls the two sets of laminating rollers 5 to work, and then conveys the two sets of films through the laminating rollers 5, and then places the preheated plastic part between the two sets of films on the conveying part 1 through an external manipulator, and realizes double-sided lamination through the movement of the plastic part and the conveyance of the two sets of films, and cuts the excess film after lamination through the cutting part 10;

[0040] Third, when the coating roller 5 needs to be dynamically balanced, the first electromagnetic block 43 is driven to stop working through the external current output device, and then the staff places the counterweight block 45 in the placement shell 44, and powers the electric spring 47 through the external power supply. At this time, the electric spring 47 is affected by the gravity of the counterweight block 45 to stretch and generate a stress field around it. This stress field will affect the resistance value of the resistance strain gauge 48, and then the resistance strain element inside the resistance strain gauge 48 will be deformed by the stress, so that the staff can calculate the length change of the electric spring 47 through the resistance value of the resistance strain gauge 48, and then indirectly calculate the length change of the electric spring 47. The weight of the counterweight 45 is calculated. When the weight reaches the required value, the first electromagnetic block 43 is driven to work through the external current output device, so that the first electromagnetic block 43 and the mounting rod 42 are magnetically adsorbed to prevent the counterweight 45 in the placement shell 44 from falling due to external factors. By increasing the counterweight and detecting the counterweight weight, the coating roller 5 always maintains a stable dynamic balance, reduces the uneven force on the film, reduces the possibility of film damage, improves the integrity of the coating, prevents the coating from wrinkles or local loose fitting, makes the film fit perfectly with the plastic surface, and at the same time reduces the additional load brought to the drive motor by the unbalanced coating roller 5.

[0041] Embodiment 2:

[0042] See also Figure 4 Compared with the first embodiment, the present invention further includes a film width adjustment mechanism 46, which includes a second electromagnetic block 461.

A transmission member 464 is fixedly connected to the right end of the mounting frame 463, and a moving rod 465 is fixedly connected to the left end of the transmission member 464.

[0044] The outer wall of the moving rod 465 is slidably connected with a sliding block 466 on both the front and rear sides, the top of the sliding block 466 is rotatably connected with a first rotating rod 467, and the bottom of the sliding block 466 is rotatably connected with a second rotating rod 468. The front and rear ends of the bottom of the mounting frame 463 are fixedly connected with a support frame 469, and the bottom of the support frame 469 is fixedly connected to the top of the first mounting plate 2, so that the support frame 469 facilitates the installation and fixation of the mounting frame 463.

[0045] The second electromagnetic block 461 is electrically connected to the external current output device, and the transmission member 464 is composed of a motor fixedly connected to the right end of the mounting frame 463, a screw fixedly connected to the left end of the motor, a limit rod fixedly connected to the inner side of the right end of the mounting frame 463, a moving block slidably connected to the limit rod and threadedly connected to the screw, and an installation sliding rod fixedly connected to the left end of the moving block.

Two groups of second rotating rods 468 are provided, and the two groups of second rotating rods 468 are rotatably connected to the bottoms of the two groups of first L-shaped rods 462 respectively.

[0047] In this embodiment:

[0048] When the width of the coating roller 5 needs to be adjusted according to the film width, the second electromagnetic block 461 is stopped through the external current output device, and then the motor in the transmission member 464 is started, and the motor in the transmission member 464 drives the screw in the transmission member 464 to rotate. The moving block in the transmission member 464 moves left and right under the influence of the cooperation between the screw in the transmission member 464 and the limit rod, and the moving block in the transmission member 464 drives the sliding rod installed in the transmission member 464 to move left and right. The sliding rod installed in the transmission member 464 drives the moving rod 465 to move left and right, and the moving rod 465 drives the two groups of sliding blocks 466 to move toward or relative to each other, so that the distance between the two groups of sliding blocks 466 gradually shortens or increases, and then the two groups of sliding blocks 466 drive the two groups of first L-shaped rods 462 to move toward or relative to each other through the rotation connection with the first rotating rod 467 and the second rotating rod 468, so that the two groups of first L-shaped The distance between the rods 462 is gradually shortened or enlarged, and the two groups of first L-shaped rods 462 drive the two groups of second electromagnetic blocks 461 to move toward or relative to each other on the outer wall of the coating roller 5, so that the distance between the two groups of second electromagnetic blocks 461 is gradually shortened or enlarged. When the two groups of second electromagnetic blocks 461 move to appropriate positions, the two groups of second electromagnetic blocks 461 are driven to work through external current output devices, so that the two groups of second electromagnetic blocks 461 and the coating roller 5 are magnetically adsorbed, and the second electromagnetic blocks 461 and the coating roller 5 are fixed. Therefore, the coating roller 5 can adapt to various specifications of films through the movement of the two groups of second electromagnetic blocks 461, without replacing coating rollers 5 of different sizes, thereby improving the versatility and flexibility of the coating roller 5, ensuring that the film always maintains the correct position and tension during the winding process, avoiding problems such as uneven coating and wrinkles caused by film width mismatch, and improving the quality and stability of the coating.
