[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an automatic laminating mechanism for a laminating machine, comprising a body 1. The body 1 is the main body of the laminating machine and serves as the mounting foundation and frame for the entire automatic laminating mechanism. All components are directly or indirectly mounted on the body 1, providing a stable support structure for the coordinated work of each component and ensuring the overall stability of the mechanism during operation. A pressing component 2 is provided on the upper left surface of the body 1, used to press the substrate and the laminating material together during the laminating process, ensuring that they maintain a stable positional relationship during conveying and laminating, and preventing wrinkles caused by loosening. To prevent wrinkles, misalignment, and other issues, thus ensuring the quality of the coating, the clamping assembly 2 includes two sets of mounting plates 23 and two sets of clamping sleeves 21. The mounting plates 23 provide support, and the two sets of clamping sleeves 21 can tighten the coating by rotating, preventing loosening from affecting the coating quality. The two sets of mounting plates 23 are respectively located on the inner left side of the machine body 1, near the front and rear sides. The two sets of mounting plates 23 are rotatably connected to a turntable 22 through a positioning rod 210. The two sets of positioning rods 210 are rotatably connected to the middle of the two sets of mounting plates 23 to support the turntable 22, and the front positioning rod 210 passes through the mounting plate 23 and is connected to the ratchet 25.

[0031] Furthermore, two sets of fixing rods 26 are fixedly connected between the two sets of turntables 22 to support the clamping sleeves 21 and allow the two sets of clamping sleeves 21 to rotate. A ratchet 25 is rotatably connected to the front surface of the front mounting plate 23. The ratchet 25 is fixedly connected to the front surface of the positioning rod 210. A fixing block 24 providing support is fixedly connected to the front surface of the front mounting plate 23 near the ratchet 25. A pawl 211 is slidably connected to the bottom end of the fixing block 24. The ratchet 25 and the pawl 211 cooperate to achieve unidirectional rotation and positioning of the turntables 22 and the two sets of clamping sleeves 21, preventing... During the pressing process, the position of the pressing sleeve 21 changes due to reverse rotation. Therefore, after the two sets of pressing sleeves 21 rotate to tighten the film, the film can always be kept taut and cannot be loosened by reverse rotation, thereby improving the tightening effect. The upper surface of the pawl 211 is fixedly connected to the slider 212, and the inner wall of the fixing block 24 is slidably connected to the groove 213. The upper surface of the slider 212 and the fixing block 24 are elastically connected by the return spring 214. The upper surface of the slider 212 is fixedly connected to the pull rod 215, which drives the pawl 211 to move upward to release the limit of the ratchet 25.

[0032] Furthermore, the pull rod 215 penetrates the upper surface of the fixing block 24 and is slidably connected to it, the pawl 211 penetrates the lower surface of the fixing block 24 and is engaged with the outer wall of the ratchet 25, and the clamping assembly 2 also includes a positioning ring 27, which is fixedly connected to the middle outer wall of the fixing rod 26, and a positioning groove 28 is provided on the middle inner wall of the clamping sleeve 21, and the positioning ring 27 is rotatably connected to the inner wall of the positioning groove 28. The positioning ring 27 and the positioning groove 28 cooperate to keep the clamping sleeve 21 always positioned in the center position to further increase the clamping effect, and the two sets of fixing rods 26 are located at the top and bottom respectively. Two sets of clamping sleeves 21 are rotatably connected to the outer walls of two sets of fixed rods 26 respectively. The slider 212 is slidably connected to the inner wall of the slide groove 213. The return spring 214 is set inside the slide groove 213. The pawl 211 is engaged in the tooth groove of the ratchet 25 under the action of the return spring 214, restricting the reverse rotation of the ratchet 25, thereby braking the positioning rod 210 and the turntable 22, ensuring that the clamping sleeve 21 clamps the material stably. The front surface of the ratchet 25 is fixedly connected to a rotating frame 29 that drives the ratchet 25, the turntable 22 and the two sets of clamping sleeves 21 to rotate.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The mounting plate 23 is fixedly installed to the body 1 via a mounting assembly 3. The mounting assembly 3 includes a plug 32 and a slot 33. The plug 32 is inserted into the slot 33 to stably support the mounting plate 23. Two sets of plugs 32 are provided and are fixedly connected to the opposite sides of the two sets of mounting plates 23. Two sets of slots 33 are provided and are respectively opened on the front and rear inner sides of the left side of the body 1. A second groove 34 is opened on the front and rear inner sides of the left side of the body 1 near the two sets of slots 33. The second slide 34 provides space for the mounting plate 23 to slide into. The mounting plate 23 is inserted into the inner wall of the second slide 34, and the insert block 32 is inserted into the inner wall of the slot 33. The left front and rear outer walls of the body 1 are threaded with locking screws 31. The locking screws 31 are threaded with the body 1 and the insert block 32, so that the mounting plate 23 can be stably installed and limited. The two sets of locking screws 31 pass through the left side of the body 1 and are threaded with the two sets of insert blocks 32 on opposite sides.

[0034] Working principle: When in use, the two sets of mounting plates 23 are inserted into the two sets of sliding grooves 34 on the front and rear inner sides of the left side of the machine body 1, respectively. At the same time, the inserts 32 on the mounting plates 23 are inserted into the slots 33 on the machine body 1. Then, the mounting plates 23 are stably installed and limited by the locking screws 31 that penetrate the front and rear surfaces of the left side of the machine body 1 and are threaded to the inserts 32. At this time, the two sets of mounting plates 23 and the two sets of clamping sleeves 21 can be installed quickly.

[0035] By passing the coating material between the two sets of clamping sleeves 21, the rotating frame 29 drives the ratchet 25, the turntable 22, and the two sets of clamping sleeves 21 to rotate. The rotation of the two sets of clamping sleeves 21 tightens the coating material. The pawl 211, under the action of the return spring 214, engages in the tooth groove of the ratchet 25, restricting the ratchet 25 from rotating in the opposite direction. This brakes the positioning rod 210 and the turntable 22, ensuring that the clamping sleeves 21 maintain a stable clamping state on the material. This prevents the clamping sleeves 21 from changing position due to reverse rotation during the clamping process, keeping the coating under tension at all times. This avoids problems such as wrinkles and displacement caused by loosening, thereby ensuring the coating quality.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
