[0015] Beneficial effects

[0016] Compared with the prior art, this utility model provides a roller changing device for a coating machine, which has the following advantages:

[0017] 1. In this solution, the frame is used to support the roller changing mechanism. The casters facilitate the relocation of the frame, and the handrails facilitate the movement of the frame. The pallets and their arc-shaped placement grooves facilitate the lifting of the coating machine rollers. The support rod slides inside the limiting grooves on the two support plates, which facilitates the height adjustment of the two pallets, thereby facilitating the height adjustment of the lifted rollers.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4 A coating machine roller changing device, comprising:

[0028] Frame 1, with multiple casters 2 fixedly installed at the bottom of frame 1, and handrails 3 fixedly installed on both outer walls of frame 1; and

[0029] The roller changing mechanism 4 includes two support plates 401. Each support plate 401 is fixedly installed on the top of the frame 1. Each support plate 401 has a limit groove on its outer wall. A support rod 402 is movably embedded between the two limit grooves. Two support plates 403 are slidably sleeved on the outer surface of the support rod 402. Each support plate 403 has an arc-shaped placement groove on its top.

[0030] In this embodiment, the frame 1 is used to support the roller changing mechanism 4. The universal wheels 2 facilitate the position transfer of the frame 1, and the handrail 3 facilitates the movement of the frame 1. The support plate 403 and its surface arc-shaped placement groove facilitate the lifting of the coating machine roller. The support rod 402 slides inside the limiting groove on the two support plates 401, which facilitates the height adjustment of the two support plates 403, thereby facilitating the height adjustment of the lifted roller, avoiding the time and effort of manual lifting, and improving the convenience of roller changing in the coating machine.

[0031] Please refer to the specific details. Figure 2-3As shown, a drive shaft 404 is rotatably embedded between the outer walls of the two support plates 401. Two gears 405 are fixedly sleeved on the outer surface of the drive shaft 404. A reinforcing plate 406 is fixedly connected between the outer walls of the two support plates 401. Two limiting plates 407 are fixedly installed on one side of the outer wall of the reinforcing plate 406. A toothed plate 408 is movably embedded between the inner walls of each limiting plate 407. Each toothed plate 408 meshes with the corresponding gear 405. The top of each toothed plate 408 is fixedly connected to the support rod 402.

[0032] In this embodiment, the rotation of the drive shaft 404 facilitates the rotation of the gear 405. Since the gear 405 meshes with the toothed plate 408, it facilitates the sliding of the toothed plate 408 inside the limiting plate 407, which in turn facilitates the lifting and lowering of the support rod 402, making it convenient to use the roller changing mechanism 4. The limiting plate 407 is fixed to the outer wall of the reinforcing plate 406, improving the stability of the toothed plate 408's movement.

[0033] Please refer to the specific details. Figure 3-4 As shown, a drive housing 5 is fixedly installed on the outer wall of one of the support plates 401. A mounting shaft 6 is rotatably connected between the drive housing 5 and the corresponding support plate 401. The mounting shaft 6 and the transmission shaft 404 are connected by a sprocket and a chain drive. A worm gear 7 is fixedly sleeved on the outer surface of the mounting shaft 6. A worm 8 is rotatably embedded on the outer wall of the drive housing 5, and the worm 8 and the worm gear 7 mesh. A handle 9 is fixedly sleeved on the outer surface of the worm 8.

[0034] In this embodiment, the handle 9 facilitates the rotation of the worm gear 8 on the drive housing 5, which in turn facilitates the rotation of the worm wheel 7, which in turn facilitates the rotation of the mounting shaft 6. Together with the chain and sprocket, it facilitates the rotation of the transmission shaft 404, thereby improving the ease of use of the roller changing mechanism 4. The worm wheel and worm gear have a self-locking function, which facilitates the adjustment of the positioning of the rear support rod 402, thereby facilitating the roller changing of the coating machine.

[0035] Please refer to the specific details. Figure 1-3 As shown, the support rod 402 consists of multiple square rods and two round rods.

[0036] In this embodiment, the pallet 403 and the limiting groove are both adapted to the square rod portion on the support rod 402. The square rod portion of the support rod 402 and the limiting groove cooperate to improve the stability of the lifting and lowering of the support rod 402. When the pallet 403 moves to the square rod portion, it is convenient to keep the pallet 403 perpendicular to the support rod 402, thereby facilitating the lifting of the coating machine roller. When the pallet 403 moves to the round rod portion on the support rod 402, it is convenient to flip it over, thereby improving the use effect of the pallet 403.

[0037] Please refer to the specific details. Figure 2 As shown, two stabilizers 10 are rotatably mounted on the outer surface of the drive shaft 404, and each stabilizer 10 is fixedly connected to the frame 1 and the reinforcing plate 406.

[0038] In this embodiment, the installation stability of the drive shaft 404 is further improved by the stabilizer 10.

[0039] Please refer to the specific details. Figure 1 As shown, a counterweight 11 is fixedly installed on the top of the frame 1.

[0040] In this embodiment, the support stability of the frame 1 is improved by using counterweight 11.

[0041] Working principle: In use, place the roller to be installed in the arc-shaped placement slot on the two support plates 403, push the handle 3, and with the universal wheels 2, move the frame 1 to the bottom of the coating machine roller. Turn the handle 9, which drives the worm gear 8 on the drive housing 5 to rotate, which in turn drives the worm wheel 7 to rotate, which in turn drives the mounting shaft 6 to rotate. With the help of the chain and sprocket, the drive shaft 404 rotates, which drives the gear 405 to rotate. Since the gear 405 meshes with the corresponding toothed plate 408, the toothed plate 408 is driven to rise inside the limiting plate 407, which drives the support rod 401 to lift upward, and drives the support plate 403 and the roller above it to the coating machine roller installation position for roller replacement.

[0042] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
