[0017] This utility model provides a guiding device for preventing coating rolls from deviating.

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A guide device for preventing coating roll from deviating includes a fixed frame 1 and a take-up roller 2 rotatably mounted on the fixed frame 1. The fixed frame 1 is provided with a motor 21 that drives the take-up roller 2 to rotate. The take-up roller 2 is driven to rotate by starting the motor 21 to take up the substrate. The start and stop of the motor 21 are controlled by an external control device.

[0019] Please refer to it again. Figure 1 and Figure 2 The fixed frame 1 is equipped with a guide mechanism, which includes two limiting plates 3 that slide inside the fixed frame 1. The limiting plates 3 have a rotating groove 31. The take-up roller 2 is located inside the rotating groove 31. A fixed box 4 is fixedly connected to the fixed frame 1. The top of the rotating groove 31 is open. After the take-up roller 2 is finished winding, it can be taken out from the open end of the rotating groove 31. The two limiting plates 3 limit the two ends of the substrate. The rotating groove 31 does not affect the normal rotation of the take-up roller 2. The distance between the two limiting plates 3 can be manually measured by a measuring tool.

[0020] Please refer to it again. Figure 1 and Figure 2 The fixed box 4 is equipped with an adjustment mechanism for adjusting the distance between the two limiting plates 3. The adjustment mechanism includes a connecting rod 6 that rotates inside the fixed box 4. A drive gear 7 is fixedly connected to the connecting rod 6. A connecting rack plate 5 is fixedly connected to the bottom of the limiting plate 3. One end of the connecting rack plate 5 extends into the interior of the fixed box 4. There are two connecting rack plates 5. The two connecting rack plates 5 are symmetrically arranged about the drive gear 7. Both connecting rack plates 5 are meshed with the drive gear 7. The connecting rod 6 is driven to rotate. Under the meshing action of the drive gear 7 and the two connecting rack plates 5, the two limiting plates 3 are driven to slide closer or further apart. The fixed box 4 has through slots on both sides for the connecting rack plates 5 to pass through.

[0021] Please refer to it again. Figure 1 and Figure 2 A fixed sliding rod 51 is fixedly connected between the fixed box 4 and the inner side wall of the fixed frame 1. A connecting slider 52 is fixedly connected to the bottom of the connecting rack plate 5. The connecting slider 52 is slidably connected to the fixed sliding rod 51. Under the action of the fixed sliding rod 51 and the connecting slider 52, the limiting plate 3 is supported to slide horizontally inside the fixed frame 1.

[0022] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4One end of the connecting rod 6 extends to the front of the fixed box 4. A movable locking block 63 is rotatably connected to the fixed box 4. A connecting turntable 61 is fixedly connected to one end of the connecting rod 6. A limiting groove 62 is provided on the connecting turntable 61. The movable locking block 63 is engaged inside the limiting groove 62. The connecting turntable 61 facilitates the rotation of the drive gear 7 inside the fixed box 4. After adjustment, the movable locking block 63 is rotated to engage inside the limiting groove 62 to limit the rotation of the connecting turntable 61.

[0023] Please refer to it again. Figure 1 , Figure 2 and Figure 5 The limiting plate 3 has a sliding groove 32 that communicates with the rotating groove 31. A leveling rod 9 is placed inside the sliding groove 32. The leveling rod 9 is located directly below the take-up roller 2. The leveling rod 9 is connected to the fixed box 4 through an elastic telescopic mechanism 8. The leveling rod 9 is used to level the substrate wound on the take-up roller 2.

[0024] Please refer to it again. Figure 1 , Figure 2 and Figure 5 The elastic telescopic mechanism 8 includes a fixed sleeve 81 fixed on the fixed box 4. A sliding rod 82 is slidably connected to the top of the fixed sleeve 81. A leveling rod 9 is fixedly connected to the top of the sliding rod 82. A fixed plate 83 is fixedly connected inside the fixed sleeve 81. The bottom of the sliding rod 82 and the fixed plate 83 are connected by a spring 84. Under the action of the spring 84, the leveling rod 9 is kept in a tight abutment with the bottom of the take-up roller 2. As the substrate is wound up, the outer diameter of the take-up roller 2 gradually expands, thereby pushing the leveling rod 9 down inside the sliding groove 32. The sliding rod 82 slides into the fixed sleeve 81.

[0025] Please refer to it again. Figure 1 , Figure 2 and Figure 5 The fixed plate 83 is provided with a through hole. The bottom of the sliding rod 82 is fixedly connected to a pressing block 86 corresponding to the through hole. The inner bottom wall of the fixed sleeve 81 is fixedly connected to a pressing switch 85. When the sliding rod 82 slides down a certain distance, the pressing block 86 presses the pressing end of the pressing switch 85. The pressing switch 85 transmits an electrical signal to the external control device, and the control device stops the rotation of the winding roller 2 to prevent over-winding.

[0026] Working principle: After the device is installed in a suitable position and connected to the municipal power supply, one end of the substrate is fixed to the outer surface of the take-up roller 2. Then, by rotating the connecting turntable 61, the drive gear 7 is driven to rotate inside the fixed box 4. The distance between the two limiting plates 3 is adjusted by the two connecting rack plates 5, so that the two limiting plates 3 guide and limit the two ends of the substrate. After adjustment, the movable locking block 63 is rotated to lock into the limiting groove 62 to limit the rotation of the connecting turntable 61. Then, the leveling rod 9 is pulled down to lower the leveling rod. One end of the leveling rod 9 is pressed against the surface of the substrate. As the substrate is wound up, the outer diameter of the winding roller 2 gradually expands, thereby pushing the leveling rod 9 down inside the sliding groove 32. The sliding rod 82 slides into the fixed sleeve 81. Under the action of the spring 84, the leveling rod 9 and the substrate surface are kept in a tight state. After one end of the sliding rod 82 slides a certain distance into the fixed sleeve 81, the pressing block 86 at the bottom of the sliding rod 82 presses the pressing end of the pressing switch 85. The pressing switch 85 transmits an electrical signal to the external control device, and the control device stops the rotation of the winding roller 2 to prevent over-winding.
