[0026] Refer to Figures 1 to 5As shown in the figure, a movable base of a belt slip switch of the present utility model includes a bracket 1; two first chutes 11 are provided at the top of the bracket 1; a plurality of fixing grooves 12 are provided in the middle of the first chute 11; a fixing plate 13 is slidably connected in the middle of the two first chutes 11; a fixing frame 14 is slidably connected to the side wall of the fixing plate 13; a deviation switch 15 is installed on the side wall of the fixing frame 14; two first screws 16 are threadedly connected in the middle of the fixing plate 13; the ends of the two first screws 16 are threaded in the middle of the fixing frame 14; two second screws 17 are threadedly connected to the bottom of the fixing plate 13; the two second screws 17 are threadedly connected inside two of the fixing grooves 12; during operation, the bracket 1 is installed beside the conveyor belt roller, the deviation switch 15 is slid on the side wall of the fixing plate 13 to adjust the position of the deviation switch 15 up and down, the two first screws 16 are turned, and the fixing frame 14 and the fixing plate 13 are connected and fixed by the two first screws 16. Then, the fixing plate 13 is moved to make the fixing plate 13 slide inside the first chute 11, and the fixing plate 13 is moved to the designated position. The two second screws 17 on the fixing plate 13 are inserted into the middle of the corresponding fixing grooves 12, and the second screws 17 are turned to connect and fix the fixing plate 13 to the bracket 1. When the roller is replaced, the second screws 17 and the first screws 16 are loosened to move the deviation switch 15 up, down, left and right, so as to adjust the position of the deviation switch 15. When the roller is replaced and installed, the fixing plate 13 is moved back to its original position and fixed by the first screws 16 and the second screws 17. The position of the deviation switch 15 can be flexibly adjusted through the fixing plate 13, which can effectively reduce the problem that the bracket 1 needs to be cut off for disassembly when the roller is replaced. There is no need to use a cutter to cut off the bracket 1 for roller replacement work, which can effectively save the time for roller installation and disassembly, effectively improve the efficiency of roller installation and disassembly, reduce the time and effort caused by the cutting method, and can effectively reduce the risk of dangerous accidents caused by high-temperature spark splashing due to frequent ignition during the roller replacement process. It can effectively reduce the physical damage such as scratches and deformation of the bracket 1 caused by the cutting work, and effectively improve the integrity and service life of the bracket 1.

[0027] Refer to Figures 1 to 5As shown, a groove 2 is formed at the top of the bracket 1; the groove 2 is formed at one end of the bracket 1; a sliding plate 21 is slidably connected to the side wall of the groove 2; two springs 22 are fixedly connected to the middle of the sliding plate 21; the end of the spring 22 is fixedly connected to a top plate 23; during operation, after the position of the fixing frame 14 is fixed, the sliding plate 21 is slid upward from the inside of the groove 2. When the sliding plate 21 slides out of the inside of the groove 2, the spring 22 is elastically stretched after being released from extrusion. The top plate 23 contacts the side wall of the fixing frame 14, and the top plate 23 presses against the side wall of the fixing frame 14. When the fixing frame 14 moves, the spring 22 contracts and the sliding plate 21 is slid into the inside of the groove 2. The top plate 23 can provide an additional support point for the fixing frame 14, effectively reducing the shaking of the fixing frame 14 during the operation of the equipment, effectively reducing the stability and accuracy of the deviation switch 15 during operation.

The suction cup 3 can make the top plate 23 closely fit on the side wall of the fixing frame 14, effectively increasing the connection strength between the top plate 23 and the fixing frame 14, effectively reducing the problem of loosening or falling off of the top plate 23 during the operation of the equipment, and making the installation and disassembly process simple and fast, effectively improving the flexibility and convenience of the connection.

[0029] Refer to Figure 1 and Figure 4As shown, a support plate 4 is fixedly connected to the top of the support 1; two second sliding grooves 41 are formed in the top of the support 1; the two second sliding grooves 41 are formed on both sides of the two first sliding grooves 11; a slider 42 is slidably connected to the middle of the first sliding groove 11; a support frame 43 is fixedly connected to the tops of the two sliders 42; an elastic cloth 44 is fixedly connected to the side wall of the support frame 43; the other end of the elastic cloth 44 is fixedly connected to the middle of the support plate 4; during operation, when the position of the fixing frame 14 is fixed, the support frame 43 is moved towards the fixing frame 14, so that the slider 42 slides inside the second sliding groove 41, and the top of the support 1 is protected by the elastic cloth 44. When the fixing frame 14 moves, the support frame 43 is moved towards the support plate 4. The elastic cloth 44 can effectively prevent dust and sundries in the working environment from falling into the first sliding groove 11, effectively reduce the accumulation of dust and impurities in the first sliding groove 11, effectively reduce the problem of blockage of the fixing groove 12 caused by the accumulation of dust and impurities, and effectively reduce the resistance suffered by the fixing plate 13 during the sliding process due to the accumulation of dust and impurities, reduce the problem of jamming or unsmooth sliding of the fixing plate 13 caused by dust and impurities, and effectively reduce the difficulty of cleaning the accumulated dust and impurities.

The bristles 5 can effectively clean the dust and impurities on the top of the support 1, can penetrate into the tiny gaps on the surface of the support 1, can effectively reduce the formation of scale due to the long-term accumulation of dirt not being cleaned in time on the surface of the support 1, effectively reduce the friction between the dust and impurities on the surface of the support 1 and the support 1 and the fixing plate 13, and effectively reduce the aggravation of wear caused by friction.

[0031] Refer to Figure 1 As shown, two first magnetic blocks 6 are fixedly connected to the side wall of the support frame 43; two second magnetic blocks 61 are fixedly connected to the side wall of the fixing plate 13; the two second magnetic blocks 61 correspond to the positions of the first magnetic blocks 6; the first magnetic blocks 6 and the second magnetic blocks 61 attract each other when approaching; during operation, when the support frame 43 approaches the surface of the fixing plate 13, the support frame 43 is attached to the fixing plate 13 by the attraction of the first magnetic blocks 6 and the second magnetic blocks 61 when approaching. When separation is required, the support frame 43 is pulled to make the first magnetic blocks 6 away from the second magnetic blocks 61. The first magnetic blocks 6 and the second magnetic blocks 61 can effectively and quickly fix the support frame 43 on the fixing plate 13, can effectively make the support frame 43 and the fixing plate 13 fit firmly, effectively reduce the sliding of the support frame 43 in the second sliding groove 41 due to vibration during the operation of the equipment, can keep the stable position of the support frame 43, reduce the problem of sliding of the support frame 43, and can realize the quick disassembly of the support frame 43 and the fixing plate 13, which is effectively convenient for maintenance and management.

[0032] Referring to Figure 4 As shown, two sponge blocks 7 are fixedly connected to the end of the support frame 43; the ends of the two sponge blocks 7 are arranged inside the first chute 11; during operation, when the support frame 43 is moving, since the ends of the sponge blocks 7 are arranged inside the first chute 11, the inside of the first chute 11 is cleaned by the sponge blocks 7. The sponge blocks 7 can penetrate into the first chute 11 to effectively remove dirt and dust adhering to the inside of the first chute 11. Moreover, the sponge blocks 7 have mobile adsorption and friction, which can effectively remove stubborn stains inside the first chute 11.

[0033] Referring to Figure 4 As shown, a drying box 8 is installed on the top of the bracket 1; the drying box 8 is arranged close to the support plate 4; during operation, the drying box 8 is placed on the bracket 1 so that the drying box 8 is stored inside the elastic cloth 44. The drying box 8 can effectively absorb moisture in the air, effectively reducing the humidity around the bracket 1, thereby effectively reducing the problem of metal components getting damp and rusty, effectively reducing damage to metal components caused by moisture, effectively keeping the bracket 1 in a dry state during operation, and effectively improving the detection accuracy and reliability of the deviation switch 15.

[0034] Working principle: Install the bracket 1 beside the conveyor belt roller. Slide the deviation switch 15 on the side wall of the fixed plate 13 and adjust the position of the deviation switch 15 up and down. Turn the two first screws 16 to connect and fix the fixing frame 14 to the fixed plate 13 through the two first screws 16. Then move the fixed plate 13 so that the fixed plate 13 slides inside the first chute 11. Move the fixed plate 13 to the specified position. Insert the two second screws 17 on the fixed plate 13 into the middle of the corresponding fixing slots 12. Turn the second screws 17 to connect and fix the fixed plate 13 to the bracket 1. When the roller is replaced, loosen the second screws 17 and the first screws 16 and move the deviation switch 15 up, down, left, and right to adjust the position of the deviation switch 15. After the roller is replaced and installed, move the fixed plate 13 back to its original position and fix it through the first screws 16 and the second screws 17. After the position of the fixing frame 14 is fixed, slide the sliding plate 21 upward from inside the groove 2. When the sliding plate 21 slides out of the inside of the groove 2, the spring 22 is elastically stretched after being released from extrusion. The top plate 23 contacts the side wall of the fixing frame 14, and the top plate 23 presses against the side wall of the fixing frame 14. When the fixing frame 14 moves, the spring 22 contracts and the sliding plate 21 slides into the inside of the groove 2. When the groove 2 slides out, when the spring 22 is elastically stretched towards the side wall of the fixing frame 14, the suction cup 3 contacts the surface of the fixing frame 14 and sucks the side wall of the fixing frame 14. After the position of the fixing frame 14 is fixed, move the support frame 43 towards one side of the fixing frame 14 so that the slider 42 slides inside the second chute 41. Protect the top of the bracket 1 through the elastic cloth 44. When the fixing frame 14 moves, move the support frame 43 towards the support plate 4. During the movement of the support frame 43, clean the top of the bracket 1 through the brush 5. When the support frame 43 approaches the surface of the fixed plate 13, the first magnet 6 and the second magnet 61 attract each other when approaching, so that the support frame 43 fits with the fixed plate 13. When separation is required, pull the support frame 43 to make the first magnet 6 away from the second magnet 61. During the movement of the support frame 43, the end of the sponge block 7 is arranged inside the first chute 11, and the inside of the first chute 11 is cleaned through the sponge block 7. Place the drying box 8 on the bracket 1 so that the drying box 8 is stored inside the elastic cloth 44.
