[0027] refer to Figure 1-7 The following describes a back roller adjustment mechanism for a coating machine used in film production, provided by an embodiment of the present invention. The back roller adjustment mechanism for a coating machine used in film production includes a frame 1. A coating roller 7 is rotatably connected inside the frame 1. A power mechanism 2 is provided at the upper end of the frame 1. Adjustment mechanisms 3 are provided on both sides of the frame 1. The power mechanism 2 provides power to the adjustment mechanisms 3. Movable seats 4 are provided on both sides inside the frame 1. A connecting component 5 is provided on the side of the movable seat 4 away from the frame 1. A back roller 6 is provided between the two connecting components 5, and the back roller 6 is located above the coating roller 7.
[0028] In use, the back roller 6 is installed between the two movable seats 4 using the connecting component 5. When the back roller 6 needs to be adjusted, the power mechanism 2 works, and there are two adjustment mechanisms 3, which can provide power to the two adjustment mechanisms 3 at the same time. With the cooperation of the adjustment mechanisms 3, the back roller 6 can be adjusted, thereby changing the distance between the back roller 6 and the coating roller 7, which is beneficial for coating different thicknesses on the film surface.
[0029] The power mechanism 2 includes a support base 201, a rotating shaft 202, a first bevel gear 203, a second bevel gear 204, and a handle 205. The support base 201 is fixedly connected to both sides of the frame 1. The rotating shaft 202 is rotatably connected inside the support base 201. The first bevel gear 203 is fixedly connected to the circumferential surface of the rotating shaft 202. There are two first bevel gears 203, which are symmetrically distributed on the rotating shaft 202. The lower end of the first bevel gear 203 meshes with the second bevel gear 204. The handle 205 is fixedly connected to both ends of the rotating shaft 202. When working, rotating the handle 205 drives the two first bevel gears 203 to rotate under the action of the rotating shaft 202, thereby driving the second bevel gear 204 to rotate, and thus providing power to the adjustment mechanism 3.
[0030] The adjusting mechanism 3 includes a fixed plate 301, a threaded rod 302, and a moving block 303. Fixed plates 301 are fixedly connected to both sides of the frame 1. Threaded rods 302 are rotatably connected inside the fixed plates 301. Two threaded rods 302 are provided and symmetrically distributed on both sides of the frame 1. The external threads of the two threaded rods 302 have opposite directions. Driven by the same rotating shaft 202, the two threaded rods 302 can rotate synchronously, thereby causing the two moving blocks 303 to move in the same direction. The upper end of the threaded rod 302 passes through the support base 201 and is rotatably connected to it. The upper end of the threaded rod 302 is fixedly connected to the second bevel gear 204. The circumferential surface of the threaded rod 302 is threadedly connected to the moving block 303, which is fixedly connected to the moving seat 4. During operation, the rotation of the second bevel gear 204 drives the threaded rod 302 to rotate, thereby driving the moving block 303 to move, which in turn drives the moving seat 4 to move, thus driving the back roller 6 to move, thereby adjusting the position of the back roller 6.
[0031] Square holes 8 are provided on both sides of the frame 1. The end of the moving block 303 away from the threaded rod 302 is located inside the square hole 8 and is slidably connected with the square hole 8. By setting the square hole 8, the moving block 303 can move easily under the action of the square hole 8 during operation.
[0032] The frame 1 has slide rails 9 fixedly connected to both sides inside, and sliders 10 are slidably connected to the slide rails 9. The sliders 10 are slidably connected to the movable seat 4. By setting the slide rails 9 and sliders 10, the movement of the movable seat 4 can be limited under the action of the slide rails 9 and sliders 10 during operation, so that the movable seat 4 can move vertically smoothly.
[0033] The connecting assembly 5 includes a support cylinder 501, a rotating cylinder 502, a locking screw 503, a moving plate 504, and a spring 505. The support cylinder 501 is fixedly connected to the side of the movable seat 4 away from the frame 1. The moving plate 504 and the rotating cylinder 502 are slidably connected inside the support cylinder 501, and the rotating cylinder 502 is rotatably connected to the moving plate 504. The locking screw 503 is threaded inside the rotating cylinder 502. The end of the back roller 6 is located inside the rotating cylinder 502. The spring 505 is fixedly connected inside the support cylinder 501. 5. Spring 505 is fixedly connected to movable plate 504. When it is necessary to disassemble back roller 6, first loosen locking screw 503, and then push rotating cylinder 502 to move rotating cylinder 502 into support cylinder 501. As rotating cylinder 502 moves, the end of back roller 6 is disengaged from rotating cylinder 502, thereby realizing the disassembly of back roller 6. At the same time, when rotating cylinder 502 moves into support cylinder 501, it can compress spring 505 with the cooperation of movable plate 504 so that rotating cylinder 502 can be reset.
[0034] A retaining plate 11 is fixedly connected to the circumferential surface of the support cylinder 501, and a retaining block 12 is fixedly connected to the circumferential surface of the rotating cylinder 502. The retaining block 12 cooperates with the retaining plate 11. By setting the retaining plate 11 and the retaining block 12, when the rotating cylinder 502 moves into the interior of the support cylinder 501 during operation, the retaining block 12 passes over the retaining plate 11. After the retaining block 12 passes over the retaining plate 11, the rotating cylinder 502 is rotated, so that the retaining block 12 is locked into the retaining hole of the retaining plate 11, thereby realizing the limitation of the rotating cylinder 502 and facilitating the disassembly of the back roller 6.
[0035] 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.
