[0002] An automatic film laminating machine is a device used to automatically apply thin films or protective films to surfaces. It is widely used in industries such as electronics, glass, sheet metal, and plastics. The operation process includes preparation, equipment commissioning, film application, quality inspection, and equipment cleaning. During the film application process, the automatic film laminating machine achieves accurate and stable application through the coordinated application of glue and film, improving the production efficiency and accuracy of the applied products.

[0003] When applying the film, the product is placed in the limiting structure, and the protective film is placed on the product. The protective film is attached to the surface of the product using a pressure roller. However, the protective film needs to be aligned with the product before attachment before subsequent operations are performed. After replacing the product, the protective film needs to be placed on the product again. The operation process is relatively cumbersome, which reduces the working efficiency of the automatic film applying machine. Utility Model Content

[0023] By placing the protective film into the feed plate 301 and fixing its position with the limit plates on both sides, after the sensor at the bottom of the feed plate 301 detects the product, the electric push rod 306 is started to move the rotating block 305 and rotate in the rotating seat 304. The rotating seat 304 drives the push plate 303 to slide in the feed plate 301 and limits the push plate 303 through the limit plates. The push plate 303 pushes the protective film on the bottom side out of the discharge chute 302 and installs it on the product, thereby facilitating pressure attachment. The size of the push plate 303 is adjusted according to the actual size of the protective film, which facilitates the complete pushing out of the protective film. At the same time, as the bottom protective film is moved out, the upper protective film slides to the bottom due to gravity, which facilitates the subsequent installation of the protective film.

[0024] A limit plate is provided on the inner wall of the feeding plate 301 , the bottom end of the limit plate is in contact with the push plate 303 , and the electric push rod 306 passes through the mounting frame 2 and extends to the outside thereof.

[0025] The top of the mounting frame 2 is fixedly connected to a cylinder 4, the bottom end of the cylinder 4 is fixedly connected to a connecting plate 5, the top of the connecting plate 5 is fixedly connected to a guide rod 6, the bottom end of the connecting plate 5 is fixedly connected to an adjusting rod 7, the surface of the adjusting rod 7 is movably sleeved with an adjusting spring 8, and the middle part of the adjusting rod 7 is rotatably connected to a pressure roller 9.

[0026] By starting the cylinder 4, the connecting plate 5 drives the pressure roller 9 to move downward, and at the same time the guide rod 6 slides in the mounting frame 2 to ensure stability during movement. After the pressure roller 9 moves down to a certain height, it contacts the protective film. The adjusting rod 7 and the adjusting spring 8 are compressed to give the pressure roller 9 a certain displacement to prevent damage to the product caused by excessive pressure. The pressure roller 9 presses the protective film, and the moving frame 16 drives the product to move, thereby completing the automatic film application of the product.

[0027] The top of the base plate 1 is fixedly connected to a support base 10, and a slide groove 11 is provided on the front and rear sides of the support base 10. The inner wall of the slide groove 11 is fixedly connected to a first limiting rod 12. The side of the support base 10 away from the mounting frame 2 is fixedly connected to a first motor 13, and the output end of the first motor 13 is fixedly connected to a first screw 14. The surface of the first screw 14 is threadedly connected to a sliding block 15, and the top of the sliding block 15 is fixedly connected to a moving frame 16.

[0028] The back of the movable frame 16 is fixedly connected to a second motor 17 , the output end of the second motor 17 is fixedly connected to a second screw 18 , the surface of the second screw 18 is threadedly connected to a sliding seat 19 , and the middle of the sliding seat 19 is slidably connected to a second limiting rod 20 .

[0029] By starting the second motor 17, the second screw 18 rotates, and the sliding seat 19 slides on the surface of the second limiting rod 20, thereby adjusting the position of the support plate 22 and the product to correspond to the position of the discharge chute 302, facilitating the precise installation of the protective film.

[0030] The top of the sliding seat 19 is fixedly connected to a support rod 21, the top of the support rod 21 is fixedly connected to a support plate 22, the left and right sides of the support plate 22 are fixedly connected to telescopic rods 23, the surface of the telescopic rod 23 is movably sleeved with a return spring 24, and the side of the telescopic rod 23 away from the support plate 22 is fixedly connected to a fixed plate 25.

[0031] There are four support rods 21 distributed at the four corners of the sliding seat 19 , two telescopic rods 23 are provided, and the two telescopic rods 23 are composed of two sliding rods. A limiting groove is provided on the top of the fixing plate 25 .

[0032] The utility model provides an automatic film laminating machine with a limiting structure, and the specific working principle is as follows:

[0033] When in use, the product is placed on the support plate 22, and the left and right sides thereof squeeze the fixing plates 25 to change the length of the telescopic rod 23 and the return spring 24 and adapt to the size of the product, thereby limiting and fixing products of different sizes, placing the protective film in the feeding plate 301, and fixing its position by the limiting plates on both sides, starting the first motor 13, rotating the first screw 14, and the sliding block 15 drives the movable frame 16 to move left and right, thereby conveying the product, and waiting for the product to move away from one side of the mounting frame 2 to the lower side of the feeding plate 301. On the other hand, the sensor on the feeding plate 301 detects the position of the product and starts the electric push rod 306 to move the rotating block 305 and rotate it in the rotating seat 304. The rotating seat 304 drives the push plate 303 to slide in the feeding plate 301 and limits the push plate 303 by the limit plate. The push plate 303 pushes the protective film on the bottom side out of the discharge chute 302 and installs it on the product. The cylinder 4 is started to make the connecting plate 5 drive the pressure roller 9 to move downward, contact the protective film and press it, thereby completing the automatic film application of the product.
