Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyors, and specifically to a belt conveyor with adaptive tension dynamic compensation. Background Art

[0002] During the operation of existing belt conveyors, problems such as slipping, deviation, or increased wear often occur due to insufficient or excessive tension of the conveyor belt, affecting the transmission efficiency and service life.

[0003] In the prior art, a conveyor with an adaptive adjustment type tensioning device, with the authorization announcement number of CN111470269B, includes a frame, a conveyor belt, a driving roller, a driven roller, a driving mechanism, and a self-adjusting tensioning device. The self-adjusting tensioning device includes a supporting device and a buffer tensioning device. The supporting device includes a first supporting roller and a second supporting roller. The buffer tensioning device includes a guide post, a guide ring buckle, a buffer spring, a fixed post, a suspension roller, and a suspension box. With the aging and elongation of the conveyor belt, the present invention can automatically reduce the tension force relying on the buffer spring, avoiding the breakage of the conveyor belt due to excessive tension after aging, thus greatly extending the service life of the conveyor belt.

[0004] Although the above solution can adapt to the problem of belt relaxation and aging, the conveyor cannot be adaptively adjusted according to the on-site working conditions, and its belt cannot adjust the conveying distance and conveying angle of the belt according to the conveying point. It is difficult for the belt tension to adapt to dynamic working condition changes, especially in the occasions where the transmission distance or angle needs to be frequently adjusted, lacking the ability of adaptive compensation. In addition, impurities are easily adhered to the surface of the conveyor belt, which requires manual cleaning, increasing the maintenance cost. Summary of the Invention

[0015] Preferably, self-locking universal wheels are fixedly connected to both sides of the bottoms of the front fixing seat, the rear fixing seat, the support seat and the moving seat. The bottoms of the plurality of self-locking universal wheels are flush with each other. During adjustment, the rear fixing seat can move according to the adjusted position.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this application, the rear fixed seat drives the lower roller to move, changing the distance between the lower roller and the upper roller, which facilitates the transmission of materials. At the same time, the rear fixed seat drives the rear bracket to move, the rear bracket drives the limiting plate to move, and the limiting plate slides inside the limiting rail, enabling the rear bracket and the front bracket to remain corresponding. This can adapt to the changed transmission angle and length after the adjustment of the rear fixed seat, and change correspondingly according to the distance between the two transmission points. At the same time, the two first hydraulic cylinders can be started to drive the side frame and the front bracket to rise, thereby driving the upper roller to rise and adjusting the angle of the conveyor belt, changing according to the height difference of different transmission points, adapting to different working environments, and having a wide range of applications.

[0017] 2. When the sliding rod moves in this application, it drives the connecting block to move, so that the connecting block drives the moving plate and the protective cover to move. When the moving plate moves, it drives the rotating shaft to move, and then drives the supporting roller to move. One end of the conveyor belt located outside the supporting roller after adjustment remains in contact under the movement of the supporting roller, so that the conveyor belt remains in a tensioned state, facilitating the transportation of goods. When the connecting block drives the moving plate to move, the supporting spring supports and limits the connecting block. At the same time, the elastic force of the supporting spring supports the connecting block and the moving plate to exert force outward, tensioning and supporting the conveyor belt. At the same time, it can make the fixed frame have elastic movement allowance, protect the conveyor belt, and prevent the conveyor belt from being pulled by a large mechanical force during the adjustment of the conveyor belt, maintaining a good operating state and improving the service life. When the conveyor belt is adjusted, it drives the supporting roller and the moving plate to move, and the moving plate drives the connecting block and the sliding rod to move, thereby limiting the piston plate. When the piston plate moves inside the moving sleeve, the buffer liquid inside the moving sleeve flows through the through hole inside the piston plate, forming a damping effect, so as to cooperate with the elastic force of the supporting spring to buffer the sliding rod, and then buffer the moving plate and the supporting roller, improving the stability of the conveyor belt during the adjustment process.

[0018] 3. In this application, the servo motor is started to drive the transmission gear to rotate. When the transmission gear rotates, it drives the transmission gear ring to rotate, so that the transmission gear ring drives the connecting sleeve to rotate. When the connecting sleeve rotates, it drives the rotating sleeve to rotate, so that the rotating sleeve drives the connecting sleeves and the first bevel gears at both ends to rotate synchronously. The first bevel gear drives the transmission rod to rotate, and drives the rotating rod to rotate through the second bevel gear transmission, thereby driving a plurality of cleaning wheels to rotate. Since the plurality of cleaning wheels are in contact with the surface of the conveyor belt, the cleaning wheels can clean the surface of the conveyor belt at the same time, cleaning the impurities adhered during the transportation process, improving the working environment, and eliminating the need for manual cleaning, which is convenient to use.

[0026] When this solution is in use, when the device is pushed to the working area, the transmission distance and transmission angle are adjusted according to the on-site situation. The motor is started to drive the self-locking lead screw 11 to rotate, and the self-locking lead screw 11 drives the moving seat 12 to move. When the moving seat 12 moves, it drives the moving frame 49 and the rear fixing seat 5 to move, so as to adjust the distance between the rear fixing seat 5 and the front fixing seat 1. After the rear fixing seat 5 moves, the rear fixing seat 5 drives the lower roller 14 to move, and the distance between the lower roller 14 and the upper roller 13 changes, which is convenient for material transmission.

When the connecting block 35 drives the moving plate 17 to move, the supporting spring 47 supports and limits the connecting block 35. At the same time, the elastic force of the supporting spring 47 supports the connecting block 35 and the moving plate 17 to exert force outwards, tension and support the conveyor belt 15. At the same time, it can make the fixed frame 16 have an elastic movement margin, which can protect the conveyor belt 15 and prevent the conveyor belt 15 from being pulled by a large mechanical force during the adjustment of the conveyor belt 15, keep a good operating state, and improve the service life. When the conveyor belt 15 is adjusted, it drives the supporting roller 20 and the moving plate 17 to move. The moving plate 17 drives the connecting block 35 and the slide bar 28 to move, so as to limit the piston plate 37. When the piston plate 37 moves inside the moving sleeve 36, the buffer liquid inside the moving sleeve 36 flows through the through hole inside the piston plate 37 to form a damping effect, so as to cooperate with the elastic force of the supporting spring 47 to buffer the slide bar 28, and then buffer the moving plate 17 and the supporting roller 20, and improve the stability of the conveyor belt 15 during the adjustment process.

[0028] The servo motor 43 is started to drive the transmission gear 44 to rotate.

The first bevel gear 32 drives the transmission rod 27 to rotate, and through the second bevel gear 33, it drives the rotating rod 24 to rotate, thereby driving a plurality of cleaning wheels 25 to rotate. Since the plurality of cleaning wheels 25 are in contact with the surface of the conveyor belt 15, the cleaning wheels 25 can clean the surface of the conveyor belt 15 at the same time, clean the impurities adhered during the transportation process, improve the working environment, and eliminate the need for manual cleaning, which is convenient to use.
