Description

Technical Field

[0001] The invention relates to the technical field of belt conveyors, in particular to a belt conveyor with adaptive tensioning force dynamic compensation. Background Art

[0002] During operation, existing belt conveyors often experience problems such as slipping, deviation, or increased wear due to insufficient or excessive belt tension, which affects transmission efficiency and service life.

[0003] Prior art discloses a conveyor with an adaptively adjustable tensioning device, with authorization publication number CN111470269B. The device comprises a frame, a conveyor belt, a driving roller, a driven roller, a drive mechanism, and a self-adjusting tensioning device. The self-adjusting tensioning device includes a support device and a buffer tensioning device. The support device comprises a first support roller and a second support roller. The buffer tensioning device comprises a guide post, a guide ring buckle, a buffer spring, a fixing post, a suspension roller, and a suspension box. As the conveyor belt ages and elongates, the buffer spring automatically reduces the tension, preventing the belt from breaking due to overtensioning and significantly extending its life.

Furthermore, the belt's conveying distance and angle cannot be adjusted based on the conveying point. Belt tensioning struggles to adapt to dynamic operating conditions, especially when the conveying distance or angle requires frequent adjustments. This lacks adaptive compensation capabilities. Furthermore, impurities easily adhere to the conveyor belt surface, requiring manual cleaning and increasing maintenance costs. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This application enables the rear fixed seat to drive the lower roller to move, and the distance between the lower roller and the upper roller to change, which is convenient for material transmission. At the same time, the rear fixed seat drives the rear bracket to move, and the rear bracket drives the limit plate to move. The limit plate slides inside the limit rail, so that the rear bracket and the front bracket remain corresponding, which can adapt to the transmission angle and length changes after the rear fixed seat is adjusted, and make corresponding changes according to the distance between the two transmission points.

[0018] 2. The sliding rod of the present application drives the connecting block to move when it moves, 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, thereby moving the support roller. After adjustment, the end of the conveyor belt located on the outside of the support roller remains in contact with the movement of the support roller, thereby keeping the conveyor belt in a tensioned state, which is convenient for transporting 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 to tension and support the conveyor belt, and at the same time, it can make the fixed frame have elastic movement margin, which can be used for It can protect the conveyor belt and prevent the conveyor belt from being pulled by a large mechanical force when adjusting the conveyor belt, thereby maintaining a good operating state and increasing its service life. When adjusting, the conveyor belt drives the support roller and the movable plate to move, and the movable plate drives the connecting block and the slide rod to move, thereby limiting the piston plate. When the piston plate moves inside the movable sleeve, the buffer inside the movable sleeve flows through the through hole inside the piston plate, forming a damping effect, thereby cooperating with the elastic force of the support spring to buffer the slide rod, and then buffer the movable plate and the support roller, thereby improving the stability of the conveyor belt during the adjustment process.

[0019] 3. The present application starts the transmission gear through a servo motor to rotate. When the transmission gear rotates, it drives the transmission ring gear to rotate, so that the transmission ring gear 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 at both ends and the first bevel gear 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, thereby driving multiple cleaning wheels to rotate.
