[0033] First, place the device on the belt bracket and make the cross plate 5 under the upper belt, then start the servo motor 82 to rotate forward, the servo motor 82 rotates forward to drive the driving screw 81 to rotate forward, the driving screw 81 rotates forward to drive the left splint 8 to move right, the left splint 8 moves right to drive the left rack 83 to move right, the left rack 83 moves right to drive the spur gear 84 to rotate forward, the spur gear 84 rotates forward to drive the right rack 83 to move left, the right rack 83 moves left to drive the right splint 8 to move left, when the right splint 8 moves left and the left splint 8 moves right and both contact with the belt bracket, the splints 8 on the left and right sides cooperate to make the fixed seat 2 directly under the upper belt, which also makes the cross plate 5 directly under the upper belt, turn off the servo motor 82, and the left and right splints 8 cooperates to fix the fixed seat 2 on the belt bracket, making the whole device more stable to use, and then start the stepper motor 63 to drive the screw rod 64 to rotate alternately forward and reverse, the screw rod 64 drives the left and right movable seats 6 to move synchronously inward and outward, and the movable seat 6 drives the left and right swing arms 61 to move synchronously inward and outward. When the left and right swing arms 61 move to a position suitable for the upper belt width support, turn off the stepper motor 63, and then twist the circular frame 78 to rotate and drive the second spline shaft 76 to rotate, the second spline shaft 76 rotates to drive the spline shaft sleeve 77 to rotate, the spline shaft sleeve 77 rotates through the bevel gear assembly to drive the first spline shaft 721 to rotate, the first spline shaft 721 rotates to drive the inner spline cylinder 72 to rotate, the inner spline cylinder 72 rotates to drive the worm 73 to rotate, and the worm 73 drives The movable worm gear 7 rotates, and the rotation of the worm gear 7 drives the left and right side swing arms 61 to swing upward. When the left and right side swing arms 61 swing upward to an angle adapted to the upper belt support, the twisting of the circular frame 78 is stopped, the second spline shaft 76 stops driving the spline shaft sleeve 77 to rotate, the worm 73 stops driving the worm gear 7 to rotate, and the worm gear 7 stops driving the swing arm 61 to swing. The swing arm 61 and the cross plate 5 form a V-shaped groove structure and are adapted to the upper belt of the belt conveyor, and the driving motor 33 can be started to drive the bidirectional screw 32 to rotate. The rotation of the bidirectional screw 32 drives the left and right side drive blocks 31 to move in a direction close to each other, and the movement of the driving block 31 drives the scissor-type lifting frame 3 to extend, and the extension of the scissor-type lifting frame 3 drives the guide frame 4 to move upward, and the guide frame 4 moves upward to drive the cross plate 5 to rotate. The plate 5 moves upward, and the cross plate 5 drives the movable seat 6 to move upward through the fixed frame 62. The movable seat 6 drives the swing arm 61 and the L-shaped plate 71 to move upward, and the L-shaped plate 71 drives the inner spline cylinder 72 to move upward and slide on the first spline shaft 721. At the same time, when the swing arm 61 and the cross plate 5 move upward and contact the upper belt, the swing arm 61 cooperates with the cross plate 5 to quickly lift the upper belt, so that the upper belt is out of contact with the roller, and the drive motor 33 is turned off. Then the roller can be replaced. When the roller is replaced, the drive motor 33 is started to drive the bidirectional screw 32 to rotate in the opposite direction. The bidirectional screw 32 rotates in the opposite direction to drive the scissor-type lifting frame 3 to retract and reset. The scissor-type lifting frame 3 is reset to drive the guide frame 4 to move downward and reset, and the guide frame 4 drives the cross plate 5 to move downward and reset.The horizontal plate 5 drives the swing arm 61 to move downward and reset through the fixed frame 62 and the movable seat 6. The swing arm 61 and the horizontal plate 5 are reset and both disengage from the upper belt. The upper belt stops being supported, and the upper belt moves and resets to contact the replaced roller. The drive motor 33 is turned off, and the circular frame 78 is twisted to rotate in the opposite direction. The circular frame 78 drives the second spline shaft 76 to rotate in the opposite direction, which makes the swing arm 61 swing downward and reset. Then the servo motor 82 is started to drive the drive screw 81 to reverse. The drive screw 81 reverses and drives the left clamping plate 8 to move to the left and reset. The left clamping plate 8 drives the right clamping plate 8 to move to the right and reset through the rack 83 and the spur gear 84.

The lower parts of the left and right side slides 9 are symmetrically slidably connected with the slide rod 91 front and back, and a clamping block 92 is fixed between the outer ends of the slide rod 91 on each side. When the clamping block 92 contacts the belt bracket, the clamping block 92 can further fix the fixed seat 2 to make the device more stable. The sides of the left and right side clamping blocks 92 that are close to each other are respectively symmetrically connected to the lower parts of the left and right side slides 9 with connecting springs 93 front and back, and the connecting spring 93 is sleeved on the slide rod 91. Electric screws 94 are installed on the left and right sides of the fixed seat 2, and the left and right side electric screws 94 are respectively threadedly connected to the left and right side slides 9.

[0035] When the clamping plates 8 on both sides are in contact with the belt bracket to clamp the fixed seat 2, the electric screw 94 is started to rotate, and the electric screw 94 rotates to drive the left and right slides 9 to move away from each other. The slide 9 drives the left and right clamping blocks 92 to move away from each other through the connecting spring 93. When the left and right clamping blocks 92 move away from each other and contact the inner side of the belt bracket, the clamping blocks 92 stop moving, and the slide 9 continues to move to compress the connecting spring 93, and the electric screw 94 is closed. The slide 9 stops moving, and the left and right clamping blocks 92 cooperate to further fix the fixed seat 2 on the belt bracket. When the roller is replaced, the electric screw 94 is started to rotate in the opposite direction. The electric screw 94 rotates in the opposite direction to drive the left and right slides 9 to move and reset in the direction of approaching each other. The left and right slides 9 move in the direction of approaching each other to reset the connecting spring 93 first, and then the left and right slides 9 drive the left and right clamping blocks 92 to move and reset in the direction of approaching each other through the connecting spring 93. The clamping blocks 92 are reset and disengaged from the belt bracket, and the electric screw 94 is closed. In this way, the fixing seat 2 can be further fixed on the belt bracket, so that the device can more stably support and hold up the upper belt.

[0037] See also Fig.11 As shown, the belt conveyor roller auxiliary replacement device also includes a rubber sleeve 11. The outer side surfaces of all guide rollers 10 are fixedly sleeved with the rubber sleeve 11 along the circumferential direction. The rubber sleeve 11 can increase the friction between the upper belt and the guide roller 10.

[0038] When the swing arm 61 and the cross plate 5 move upward, the swing arm 61 and the cross plate 5 drive the guide roller 10 to move upward, and the guide roller 10 moves upward to contact the upper belt. The swing arm 61 and the cross plate 5 support and lift the upper belt through the guide roller 10. In this way, the upper belt can be supported and lifted without stopping the belt conveyor. The rotation of the upper belt drives the guide roller 10 to rotate, and the guide roller 10 supports and guides the upper belt. When the roller is replaced, the swing arm 61 and the cross plate 5 move downward to reset and drive the guide roller 10 to move downward to reset. The guide roller 10 resets and disengages from the upper belt. In this way, the upper belt can be replaced without stopping the machine, so as not to affect the use of the belt conveyor.

[0039] When the guide roller 10 moves upward, the guide roller 10 moves upward and drives the rubber sleeve 11 to move upward and contact the upper belt. The guide roller 10 guides the upper belt through the rubber sleeve 11. The rubber sleeve 11 increases the friction between the upper belt and the upper belt, so that the guide roller 10 guides the upper belt more stably, thereby improving the stability of the upper belt guidance. When the guide roller 10 moves downward to reset, the guide roller 10 drives the rubber sleeve 11 to move downward to reset.
