Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to an automatic correction roller. Background Technology

[0002] A belt conveyor is a conveyor that uses a belt to transport materials.

[0003] Existing conveyors have the following shortcomings in use:

[0004] In the belt conveyor industry, belt misalignment is a common problem. The usual solution is to adjust the tail roller with a screw, which requires manual adjustment, increases the workload of on-site staff, and must be done while the conveyor is stopped, which will delay the customer's production schedule. Utility Model Content

[0005] The purpose of this invention is to solve the problem of conveyor belt misalignment, a common issue in the belt conveyor industry. The usual solution is to adjust the tail roller with a screw, which requires manual adjustment, increases the workload of on-site personnel, and must be done while the conveyor is stopped, which delays the customer's production schedule. Therefore, this invention proposes an automatic misalignment roller.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic alignment roller includes a base, a rotating rod rotatably connected to the top of the base via a bearing, an adjusting frame fixedly mounted on the top of the rotating rod, and fixing plates fixed to both sides of the top of the adjusting frame via bolts. The same alignment roller is rotatably connected to one side of the two fixing plates.

[0008] The alignment mechanism, mounted on the base, is used to adjust the alignment roller left and right.

[0009] The sensing mechanism is mounted on the fixed plate and is used to sense the conveyor belt.

[0010] In one possible design, the correction mechanism includes a frame, a correction motor, a gear, and an arc-shaped rack. The bottom of the frame is fixedly connected to one side of the top of the base. The top of the correction motor is fixedly connected to the inner wall of the top of the frame. The output end of the correction motor passes through the top of the frame and is fixedly connected to the bottom of the gear. One side of the arc-shaped rack is fixedly connected to one side of the inner wall of the adjustment frame. The gear meshes with the arc-shaped rack. The correction motor is a stepper motor.

[0011] In one possible design, the sensing mechanism includes a right deviation switch and a left deviation switch. A first short plate and a second short plate are fixedly mounted on the top of the two fixed plates, respectively. One side of the right deviation switch is fixedly connected to one side of the first short plate, and one side of the left deviation switch is fixedly connected to one side of the second short plate.

[0012] In one possible design, a triangular plate for improving the stability of the arc-shaped rack is welded to one side of the adjustment frame, and one side of the triangular plate is fixedly connected to one side of the arc-shaped rack.

[0013] In one possible design, a control box for controlling the correction motor is fixedly mounted on one side of the base.

[0014] In one possible design, a U-shaped mounting bracket is fixed to one side of each of the two mounting plates. A cleaning brush for cleaning dust from the surface of the alignment roller is fixed to the inner wall of one side of the mounting bracket, with the bristles of the cleaning brush fitting against the alignment roller. Dust hoods are fixed to the top and bottom of the mounting bracket, with a dust inlet on one side of each dust hood. A dust collection box is fixed to one side of one of the mounting plates, with a second fan for dust collection fixed to one side of the dust collection box. The dust inlet of the second fan is connected to the dust collection box. A sealing plate is bolted to one side of the dust collection box, with a sealing ring on one side of the sealing plate to improve sealing. Slots are provided on the top and bottom inner walls of the dust collection box, with the same filter screen inserted into both slots. A suction pipe is fixed to and connected to one side of the dust hood, with the other end of the suction pipe fixedly connected to and connected to one side of the dust collection box.

[0015] In one possible design, blower boxes are fixedly installed on both sides of the top of the base. A fan for blowing away small debris from the top of the base is fixedly installed on one side of the blower box. The air outlet of the fan is connected to the blower box. An air outlet is opened at the bottom of one side of the blower box.

[0016] In one possible design, grooves are provided at the bottom of both ends of the adjustment frame, and a universal sleeve is fixedly provided on the top inner wall of the groove. A universal ball is movably provided on the inner wall of the universal sleeve to improve the stability of the adjustment frame, and the universal ball rolls with the top of the base.

[0017] In this application, before use, the adjusting roller is placed below the belt and in contact with it. At this time, the belt is positioned between the left and right misalignment switches. When the belt deviates and hits either the left or right misalignment switch, the switch sends a signal to the control box. The control box then supplies power to the correction motor, which operates. The output shaft of the correction motor drives the gears to rotate. As the gears rotate, the arc-shaped rack moves the adjusting frame left and right, thereby adjusting the position of the adjusting roller and causing it to deflect at an angle. The control box can automatically adjust the offset angle of the adjusting roller according to the travel of the misalignment switch. After the adjusting roller deflects, it begins to correct the belt, bringing it back to the center direction. This allows for automatic belt adjustment to prevent misalignment, eliminating the need for manual adjustment, reducing the labor intensity and number of workers required on-site, and protecting workers from on-site work, thus reducing labor costs. Furthermore, belt adjustment can be performed without stopping the machine, and the system continuously monitors belt misalignment, improving the company's production efficiency. During the rotation of the adjustment frame, the omnidirectional ball will roll on the base, supporting both ends of the adjustment frame. When there are small debris at the bottom of both ends of the adjustment frame (on the base), the fan is activated. The fan generates airflow, which blows through the nozzle onto the surface of the base, thus removing the small debris and allowing the omnidirectional ball to roll on the base. Since the alignment roller is in contact with the belt, the belt will drive the alignment roller to rotate. During rotation, the surface of the alignment roller can be cleaned with a cleaning brush. The second fan is activated, generating suction. The cleaned dust is sucked into the dust collection box through the dust hood and suction pipe, filtered and intercepted by the filter screen in the dust collection box, and discharged through the outlet of the second fan. It should be noted that the fan and the second fan need to be controlled by an external controller and powered by an external power source. The power of the fan and the second fan can be selected according to actual needs. The cleaning brush can be made of wool, and the specific material can be selected according to actual needs.

[0018] The beneficial effects of this utility model are as follows:

[0019] In this utility model, the automatic belt-aligning roller, through a belt-aligning mechanism, operates a belt-aligning motor. The output shaft of the belt-aligning motor drives a gear to rotate. As the gear rotates, the arc-shaped rack moves the adjusting frame left and right, thereby adjusting the position of the belt-aligning roller and causing the roller to deflect at an angle. The control box can automatically adjust the offset angle of the belt-aligning roller according to the travel of the belt deviation switch. After the belt-aligning roller deflects, it begins to correct the belt, bringing the belt back to the center direction. This allows for automatic belt adjustment to prevent belt deviation, eliminating the need for manual adjustment, reducing the labor intensity and number of workers on site, and protecting workers from on-site work, thus reducing labor costs for the enterprise. At the same time, belt adjustment can be performed without stopping the machine, and belt deviation can be monitored at all times, improving the enterprise's production efficiency.

[0020] In this utility model, the automatic belt-correcting roller, through a sensing mechanism, when the belt deviates and encounters the left or right belt deviation switch, the belt deviation switch sends a signal to our control box, thereby sensing the belt.

[0021] In this invention, the belt can be automatically adjusted through the correction mechanism and the sensing mechanism to prevent deviation, eliminating the need for manual adjustment, reducing the labor intensity and number of workers on site, and also protecting workers by eliminating the need to work on site, thus reducing the company's labor costs. At the same time, the belt can be adjusted without stopping the machine, and the belt deviation can be monitored at all times, improving the company's production efficiency.
