[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0034] Please refer to the following: Figures 1 to 3 As shown, the following describes a film guiding mechanism for surface coating of aluminum profile 6 provided in an embodiment of this application. The film guiding mechanism for surface coating of aluminum profile 6 of this utility model includes a worktable 1, a pressing assembly 2, an unwinding assembly 3, a first guiding assembly 4, a driving assembly 42, and a second guiding assembly 5. The worktable 1 is used to receive the pressing assembly 2, the unwinding assembly 3, and the aluminum profile 6 to be coated. The pressing assembly 2 and the unwinding assembly 3 are respectively arranged on opposite sides of the worktable 1. The pressing assembly 2 can be a prior art coating device used to press the protective film 7 onto the outer side of the aluminum profile 6.

[0035] In this embodiment, the pressing assembly 2 includes a support roller 21 rotatably mounted on the worktable 1 and a pressure roller 22 rotatably mounted above the support roller 21. A lifting assembly for driving the pressure roller 22 to rise and fall is mounted on the worktable 1. Specifically, the lifting assembly includes a frame 23, a square sleeve 24, a slider 25, a U-shaped frame 26, a screw 27, and a second rocker arm 28. The square sleeve 24 is a hollow cylinder with an open bottom, and its interior is square. The square sleeve 24 is fixed to the top of the frame 23. The slider 25 is slidably disposed inside the square sleeve 24. The outer wall of the slider 25 is adapted to the inner wall of the square sleeve. The bottom end of the slider 25 passes through the square sleeve 24. The U-shaped frame 26 is fixed to the bottom end of the slider 25. The pressure roller 22 is rotatably disposed inside the U-shaped frame 26. The screw 27 is vertically disposed in the square sleeve 24 and is rotatably connected to the top end of the square sleeve 24. The slider 25 has a threaded hole for screwing the screw 27 through the threaded hole. The top end of the screw 27 passes through the top surface of the square sleeve 24 and is fixedly connected to the second rocker arm 28.

[0036] During implementation, the aluminum profile 6 is placed on the workbench 1, and the support roller 21 supports the aluminum profile 6. When the protective film 7 passes between the support roller 21 and the pressure roller 22, the rocker arm is rotated. Through the cooperation of the screw 27 and the slider 25, the slider 25 moves closer to the support roller 21, thereby driving the U-shaped frame 26 and the pressure roller 22 to move downward, pressing the protective film 7 onto the surface of the aluminum profile 6. It should be noted that a first motor (not shown in the figure) is provided on one side of the support roller 21 to drive the rotation of the support roller 21. This allows the aluminum profile 6 to move through the support roller 21, and the pressure roller 22 to press the protective film 7. During the movement of the aluminum profile 6, the protective film 7 is pulled to move synchronously, thereby driving the unwinding roller 31 to continuously release the protective film 7. By setting up a lifting assembly, the distance between the pressure roller 22 and the support roller 21 can be easily adjusted, ensuring the stability and reliability of the pressing effect.

[0037] In this embodiment, side plates 11 are fixed on both sides of the workbench 1 in the width direction. The unwinding assembly 3 includes an unwinding roller 31, a guide roller group 32, and a positioning roller 33 rotatably disposed between the two side plates 11. The unwinding roller 31, the guide roller group 32, and the positioning roller 33 are arranged sequentially downward along the upper part of the side plates 11 towards the pressing assembly 2. Specifically, the unwinding roller 31 is used to receive the rolled protective film 7. The guide roller group 32 includes a first rotating roller 321, a second rotating roller 322, and a third rotating roller 323 arranged at intervals from top to bottom. The gap between the first rotating roller 321, the second rotating roller 322, and the third rotating roller 323 is greater than the thickness of the protective film 7. The horizontal height of the bottom end of the positioning roller 33 is the same as the horizontal height of the top end of the support roller 21.

[0038] During implementation, the unwinding roller 31 rotates to release the protective film 7. The protective film 7 passes sequentially through the first rotating roller 321, the second rotating roller 322, and the third rotating roller 323 of the guide roller group 32, and then through the positioning roller 33 before extending towards the pressing assembly 2. The guide roller group 32 and the positioning roller 33 guide the transmission path of the protective film 7, enabling the protective film 7 to be transmitted smoothly and accurately to the pressing assembly 2.

[0039] Preferably, a tensioning assembly 34 is provided between the unwinding roller 31 and the guide roller group 32. Two slide grooves 111 are arranged opposite to each other on the two side plates 11. The tensioning assembly 34 includes bearing seats 341 that are slidably disposed in the two slide grooves 111 and tensioning rollers 342 that are rotatably disposed in the two bearing seats 341. Each slide groove 111 is provided with a compression spring 343, and each compression spring 343 abuts against the bottom surface of the corresponding bearing seat 341 and the bottom surface of the slide groove 111.

[0040] During implementation, the unwinding roller 31 rotates to release the protective film 7. The protective film 7 first passes around the tensioning roller 342 and then enters the guide roller group 32. During the movement of the protective film 7, the tensioning assembly 34 tensions the protective film 7 through the action of the compression spring 343. When the tension of the protective film 7 changes, the bearing seat 341 slides in the slide groove 111, driving the tensioning roller 342 to move up and down. At the same time, the compression spring 343 will generate corresponding elastic deformation according to the movement of the bearing seat 341, always applying an upward elastic force to the bearing seat 341, so that the tensioning roller 342 maintains a certain tension on the protective film 7, so that the protective film 7 always maintains a suitable tension during the transmission process, avoiding the protective film 7 from breaking due to excessive tension or loosening due to insufficient tension, thus ensuring the smooth progress of the coating process and the coating quality.

[0041] In this embodiment, the first guide assembly 4 is disposed between the pressing assembly 2 and the unwinding assembly 3, and is used to limit and guide the protective film 7. The first guide assembly 4 includes two guide rollers 41 and a drive assembly 42. The two guide rollers 41 are vertically arranged and spaced apart on both sides of the width direction of the protective film 7 to limit the protective film 7 and prevent the protective film 7 from shifting. The drive assembly 42 is used to drive the two guide rollers 41 to move towards each other or away from each other, so that by adjusting the position of the two stops 53, it can better adapt to protective films 7 of different widths.

[0042] Specifically, the drive assembly 42 includes a box 421 with an open top, two first moving blocks 422 slidably disposed within the box 421, and a first left and right helical screw 423 rotatably disposed within the box 421. The two first moving blocks 422 are respectively screwed to the two ends of the first left and right helical screw 423, and the bottom ends of two guide rollers 41 are respectively fixedly connected to the two first moving blocks 422. In implementation, when the first left and right helical screw 423 is rotated, since the two first moving blocks 422 are respectively screwed to the two ends of the first left and right helical screw 423, when the first left and right helical screw 423 rotates, the two first moving blocks 422 will move linearly towards or away from each other within the box 421 along the first left and right helical screw 423, thereby driving the two guide rollers 41 to move synchronously. This allows for convenient adjustment of the distance between the two guide rollers 41 according to the width of the protective film 7, improving the accuracy of the limiting guidance and the ease of operation.

[0043] In this embodiment, the second guide assembly 5 is disposed between the two side plates 11. The second guide assembly 5 includes a second left and right helical screw 51, a second moving block 52, a stop block 53, and a connecting rod 54. The second left and right helical screw 51 is rotatably disposed between the two side plates 11 and located on one side of the second rotating roller 322. There are two second moving blocks 52, which are respectively screwed to the two ends of the second left and right helical screw 51. The two stop blocks 53 are slidably sleeved on the outside of the second rotating roller 322, and the two stop blocks 53 can rotate relative to the second rotating roller 322. The two stop blocks 53 are respectively fixedly connected to the two second moving blocks 52 through the connecting rod 54.

[0044] In practice, rotating the second left and right helical screws 51 causes the two second moving blocks 52 to move linearly closer to or further away from each other along the second left and right helical screws 51. This, in turn, drives the two stop blocks 53 to slide on the second rotating roller 322 via the connecting rod 54. This, combined with the second guiding assembly 5, further limits and guides the protective film 7, ensuring that the protective film 7 does not shift during transport and improving the accuracy and quality of the coating process.

[0045] It should be noted that the two stops 53 are located on opposite sides of the protective film 7 in the width direction. Preferably, each stop 53 has a conical structure, with the end of the two stops 53 that is closer to each other having a smaller diameter. It should be noted that when the protective film 7 shifts during transmission, because the two stops 53 have a conical structure, the protective film 7 will move from the end of the stop 53 with a larger diameter to the end with a smaller diameter, thus better limiting the edge of the protective film 7.

[0046] In this embodiment, one end of the first left-right helical screw 423 and the second left-right helical screw 51 extends outward through the side plate 11 and is respectively fixedly fitted with a sprocket 43. A chain 44 is fitted around the outside of the two sprockets 43. The two sprockets 43 are connected by the chain 44. When the first left-right helical screw 423 or the second left-right helical screw 51 is rotated, the corresponding sprocket 43 will rotate accordingly. Through the transmission of the chain 44, the other sprocket 43 will rotate, thereby realizing the synchronous adjustment of the first guide component 4 and the second guide component 5, ensuring the consistency of the limiting and guiding effect of the first guide component 4 and the second guide component 5 on the protective film 7. Preferably, one end of one of the left-right helical screws is fixedly provided with a first rocker arm 45 to facilitate the operator to manually rotate the first left-right helical screw 423 or the second left-right helical screw 51.

[0047] In a specific implementation of this utility model, the aluminum profile 6 is placed on the workbench 1, and the rolled protective film 7 is mounted on the unwinding roller 31. The protective film 7 passes sequentially around the tension roller 342, the first rotating roller 321, the second rotating roller 322 and the third rotating roller 323, the positioning roller 33, then passes between the two stop rollers 41 of the first guide assembly 4, and finally extends to between the support roller 21 and the pressure roller 22 of the pressing assembly 2, so as to press the protective film 7 onto the surface of the aluminum profile 6.

[0048] Then, the first rocker arm 45 is rotated so that the first left and right helical screws 423 and the second left and right helical screws 51 rotate synchronously through the sprocket 43 and the chain 44. In this way, the distance between the two stop rollers 41 and the two stop blocks 53 can be adjusted according to the width of the protective film 7 to limit and guide the protective film 7 and prevent it from deviating.

[0049] Next, the second rocker arm 28 is rotated, causing the slider 25 to descend via the screw 27. This moves the U-shaped frame 26 and the pressure roller 22 downwards, pressing the protective film 7 onto the surface of the aluminum profile 6. Then, the first motor is started to drive the support roller 21 to rotate, moving the aluminum profile 6. Simultaneously, as the aluminum profile 6 moves, the protective film 7 is pulled to move synchronously, which in turn drives the unwinding roller 31 to continuously release the protective film 7, completing the film coating. During this process, the tensioning assembly 34 uses the compression spring 343 to tension the tensioning roller 342 on the protective film 7. When the tension of the protective film 7 changes, the bearing seat 341 slides within the groove 111, causing the tensioning roller 342 to move up and down. The compression spring 343 then undergoes corresponding elastic deformation, maintaining the protective film 7 in a suitable tension state.

[0050] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
