Description

Technical Field

[0002] Belt edge anti-chewing devices are important components used to protect the edges of conveyor belts in belt conveyors. They aim to prevent edge chewing during operation, thereby extending the belt's service life and improving conveying efficiency. Existing belt edge anti-chewing devices generally utilize guide wheels or guide plates installed on both sides of the conveyor belt to help guide its movement and prevent deviation. However, when deviation occurs due to external lateral forces, they lack the ability to actively adjust, still requiring downtime for maintenance, reducing production efficiency and posing production risks.

[0015] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] like Figures 1-2As shown, a belt edge anti-chewing device includes: several base frames, two channel steels 1, several idler roller supports 2, and anti-chewing brackets; each base frame includes two support legs 3 and a crossbeam 4, the two support legs 3 are arranged opposite each other, and the two ends of the crossbeam 4 are fixedly connected to the two support legs 3; the several base frames are arranged in parallel; the two channel steels 1 are respectively arranged on the top of the support legs 3 on both sides and fixedly connected to the support legs 3; the several idler roller supports 2 are arranged in parallel with the base frames, and the two ends of the idler roller supports 2 are respectively fixedly installed on the top of the two channel steels 1. An anti-chewing bracket is installed between two sets of idler roller brackets 2. The anti-chewing bracket includes a support rod 5. The bottom of the support rod 5 is fixedly installed on the top of the channel steel 1. The top of the support rod 5 is fixedly connected to an inclined rod 6 that tilts inward toward the device. A limit block 7 is fixedly installed on the top of the inclined rod 6. An infrared detection device 8 is installed on the limit block 7. An electric push rod 9 is fixedly installed on the inclined rod 6. The fixed end of the electric push rod 9 is fixedly installed on the outside of the inclined rod 6. The telescopic end of the electric push rod 9 passes through the inclined rod 6 and is fixedly connected to a roller frame 10.

[0018] Specifically, the belt is laid above the idler bracket 2, and the roller frame 10 guides the belt along a predetermined track and protects the belt edge. The infrared detection device 8 detects the position of the belt edge. When the belt is detected to be deviating, the electric push rod 9 extends and retracts to push the roller frame 10 to correct the belt. When the belt is detected to return to its original position, the electric push rod 9 extends and retracts back to its original position.

[0019] A pair of roller frames 10 are mounted opposite each other on the crossbeam 4. The return belt passes over the crossbeam 4, and the roller frames 10 on the crossbeam 4 guide and protect the belt.

[0020] The roller frame 10 includes a support plate 101, with mounting plates 102 fixedly installed at both ends of the support plate 101. Mounting holes are fixedly formed on the mounting plates 102, and bearings 103 are fixedly installed in the mounting holes. A rotating rod 104 is rotatably connected to the bearings 103, and an anti-wear roller 105 is fixedly installed on the outer side of the rotating rod 104. The anti-wear roller 105 rotates when in contact with the belt, reducing friction and minimizing belt wear.

[0021] The anti-wear roller 105 is a hyperboloid, which facilitates the limiting of the belt.

[0022] The limiting block 7 has several limiting holes 70, and the infrared detection device 8 is inserted into any one of the limiting holes 70. The infrared detection device 8 can be placed in different limiting holes 70 according to the width of the belt, improving the adaptability of the device.

[0023] A controller 11 is fixedly installed on the anti-chewing bracket. The controller 11 is electrically connected to the infrared detection device 8 and the electric push rod 9. The controller 11 is a brushless DC motor controller, and the model number WKBC170-30 can be selected.

[0024] The working principle of this utility model is as follows: the belt is laid above the idler bracket 2, and the roller frame 10 guides the belt to travel along a predetermined track; the anti-wear roller 105 rotates when in contact with the belt to reduce friction and reduce wear on the belt; the infrared detection device 8 detects the position of the belt edge, and when the belt is detected to be deviated, the infrared detection device 8 sends a signal to the controller 11, and the controller controls the electric push rod 9 to extend and retract to push the roller frame 10 to correct the belt.

[0025] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
