Description

Technical Field

[0001] This utility model relates to belt conveyors, specifically to an automatic belt correction conveyor. Background Technology

[0002] A belt conveyor, also known as a rubber belt conveyor or belt conveyor, is a machine that uses friction to continuously transport materials. It mainly consists of a frame, conveyor belt, idlers, rollers, tensioning devices, and transmission devices. During use, the conveyor belt may deviate, requiring correction.

[0003] Patent CN211418627U discloses a belt correction device for a belt conveyor, including multiple belt correction mechanisms. Each belt correction mechanism includes a bracket vertically fixed to the intermediate frame of the belt conveyor. Rotatable upper and lower idlers are respectively installed at the upper and lower ends of the bracket. The middle part of the upper idler is positioned opposite to the edge of the upper belt of the belt conveyor to block the upper belt from deviating and to provide friction to drive the upper belt back to center. The middle part of the lower idler is positioned opposite to the edge of the lower belt of the belt conveyor to block the lower belt from deviating and to provide friction to drive the lower belt back to center.

[0004] The belt correction device of this belt conveyor relies on the frictional force of contact with the lower belt to drive the lower belt back to center. When the deviation is more serious, it is difficult to complete the correction requirement by relying on this method alone. Utility Model Content

[0006] To achieve the above objectives, this utility model provides an automatic belt-aligning conveyor, including a frame and a drive roller and a driven roller mounted at both ends of the frame. A transmission belt is fitted over the drive roller and the driven roller. A drive motor unit connected to the drive roller is mounted on the frame. A sliding tension seat is mounted on the bottom of one end of the driven roller on the frame. One end of the sliding tension seat is provided with a first U-shaped seat, and the other end is provided with a second U-shaped seat. Movable blocks are provided inside both the first and second U-shaped seats. The upper and lower ends of the movable blocks... The first U-shaped seat has a rotating shaft at one end.

An extension plate is provided at the end of the second U-shaped seat facing the driving roller shaft. The extension plate is hinged to the movable block on the same side by a first hydraulic cylinder. The center of the movable block has a roller shaft hole. The end shaft of the driven roller shaft passes through the frame and the first or second U-shaped seat and is installed into the roller shaft hole by a bearing.

[0007] Preferably, the frame has elongated holes on both sides for the driven roller shaft end to pass through, and the inner sides of the first U-shaped seat and the second U-shaped seat are both provided with U-shaped clearance openings for the driven roller shaft end to pass through.

[0008] Preferably, the inner sides of both the first U-shaped seat and the second U-shaped seat are provided with guide rails, and both sides of the frame are provided with guide rail grooves that slide in cooperation with the guide rails.

[0009] Preferably, the end of the extension plate facing the drive roller on the same side as the extension plate has a notch, a pin is provided in the notch, and the head of the first cylinder is provided with a sleeve that is rotatably connected to the pin.

[0010] Preferably, a U-shaped frame plate is provided at the bottom of the frame, and a second hydraulic cylinder is installed on the U-shaped frame plate. The shaft end of the second hydraulic cylinder is connected to a connecting block provided on the bottom surface of the sliding tension seat.

[0011] Preferably, the drive motor assembly includes at least one geared motor axially connected to the drive roller shaft, and the two ends of the drive roller shaft are connected to the frame via bearings.

[0012] According to the above technical solution, this utility model provides an automatic belt-aligning conveyor, including a frame and a drive roller and a driven roller mounted at both ends of the frame. A transmission belt is fitted over the drive roller and the driven roller. A drive motor unit connected to the drive roller is mounted on the frame. A sliding tension seat is mounted on the bottom of one end of the driven roller on the frame. One end of the sliding tension seat is provided with a first U-shaped seat, and the other end is provided with a second U-shaped seat. Movable blocks are provided inside both the first and second U-shaped seats. The upper and lower ends of the movable blocks... The first U-shaped seat has a rotating shaft at one end. The upper and lower ends of the first U-shaped seat have shaft holes corresponding to the rotating shaft. The upper and lower ends of the second U-shaped seat have arc-shaped holes corresponding to the rotating shaft. The arc-shaped holes are concentric with the shaft holes. An extension plate is provided at the end of the second U-shaped seat facing the driving roller shaft.

The end shaft of the driven roller shaft passes through the frame and the first or second U-shaped seat and is installed into the roller shaft hole by a bearing.

[0013] The automatic belt-aligning conveyor works as follows: First, a sliding tensioning seat drives the first and second U-shaped seats at both ends to move synchronously, thus synchronizing the movement of the driven roller shaft installed between them and achieving tensioning. When the conveyor belt deviates from its designated path, a first hydraulic cylinder drives an adjacent movable block to swing around the shaft hole, causing the driven roller shaft to swing. The swinging of the driven roller shaft changes the force distribution on the conveyor belt's surface, thereby correcting the belt's deviation. Users can select the swing position and distance of the driven roller shaft according to the direction of belt deviation. If necessary, the sliding tensioning seat can be moved outward to provide greater tension and improve the corrective effect.

Detailed Implementation

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0025] See Figure 1-5 The automatic belt alignment conveyor shown includes a frame 1 and a drive roller 3 and a driven roller 11 mounted at both ends of the frame 1. A transmission belt 2 is fitted over the drive roller 3 and driven roller 11. A drive motor 4 connected to the drive roller 3 is mounted on the frame 1. A sliding tension seat 5 is mounted on the bottom of one end of the driven roller 11 on the frame 1. One end of the sliding tension seat 5 is provided with a first U-shaped seat 21, and the other end is provided with a second U-shaped seat 6. Movable blocks 7 are provided inside both the first U-shaped seat 21 and the second U-shaped seat 6. A rotating shaft 13 is provided at the upper and lower ends of the movable block 7. The upper and lower ends of the first U-shaped seat 21 are provided with shaft holes corresponding to the rotating shaft 13. The upper and lower ends of the second U-shaped seat 6 are provided with arc-shaped holes 12 corresponding to the rotating shaft 13. The arc-shaped holes 12 are concentric with the shaft holes. An extension plate 14 is provided at the end of the second U-shaped seat 6 facing the driving roller shaft 3. The extension plate 14 is hinged to the movable block 7 on the same side through a first oil cylinder 15. A roller shaft hole is provided at the center of the movable block 7. The end shaft 19 of the driven roller shaft 11 passes through the frame 1 and the first U-shaped seat 21 or the second U-shaped seat 6 and is installed into the roller shaft hole through a bearing 18.

[0026] By implementing the above technical solution, the sliding tensioning seat 5 first drives the first U-shaped seat 21 and the second U-shaped seat 6 at both ends to move synchronously, thereby achieving the synchronous movement of the driven roller shaft 11 installed between them, thus completing the tensioning purpose. When the transmission belt 2 deviates, the first hydraulic cylinder 15 drives the adjacent movable block 7 to swing around the shaft hole, causing the driven roller shaft 11 to swing. Due to the swing of the driven roller shaft 11, the force distribution on the surface of the transmission belt 2 on the driven roller shaft 11 changes, thereby achieving the purpose of correction. The user can select the swing position and distance of the driven roller shaft 11 according to the direction of deviation of the transmission belt 2. If necessary, the sliding tensioning seat 5 can be moved outward to provide greater tension and improve the correction effect.

[0027] In this embodiment, the frame 1 has elongated holes 9 on both sides for the end of the driven roller shaft 11 to pass through, and the inner sides of the first U-shaped seat 21 and the second U-shaped seat 6 are both provided with U-shaped clearance openings 8 for the end of the driven roller shaft 11 to pass through. With this arrangement, the elongated holes 9 and U-shaped clearance openings 8 are provided for the end shaft 19 to pass through in order to install the end shaft 19 of the driven roller shaft 11 into the movable blocks 7 at both ends. The elongated holes 9 and U-shaped clearance openings 8 also provide clearance when the driven roller shaft 11 swings.

[0028] In this embodiment, guide rails 22 are provided on the inner sides of both the first U-shaped seat 21 and the second U-shaped seat 6, and guide rail grooves 10 that slide in cooperation with the guide rails 22 are provided on both sides of the frame 1. This arrangement provides guidance for the first U-shaped seat 21 and the second U-shaped seat 6 during tensioning.

[0029] In this embodiment, the end of the extension plate 14 facing the drive roller 3 on the same side as the extension plate 14 has a notch, and a pin 17 is disposed in the notch. The head of the first hydraulic cylinder 15 is provided with a sleeve 16 that is rotatably connected to the pin 17. With this arrangement, a rotatable connection is achieved between the head of the first hydraulic cylinder 15 and the movable block 7 on the same side. The extension plate 14 is also provided with a hinge seat for mounting the bottom of the first hydraulic cylinder 15.

[0030] In this embodiment, a U-shaped frame plate 23 is provided at the bottom of the frame 1, and a second hydraulic cylinder 24 is mounted on the U-shaped frame plate 23. The shaft end of the second hydraulic cylinder 24 is connected to a connecting block 20 provided on the bottom surface of the sliding tensioning seat 5. With this arrangement, the second hydraulic cylinder 24 drives the sliding tensioning seat 5 to move back and forth.

[0031] In this embodiment, to further provide a drive motor assembly 4, the drive motor assembly 4 includes at least one reduction motor axially connected to the drive roller 3, and the two ends of the drive roller 3 are connected and installed to the frame 1 through bearings 18.

[0032] The automatic belt straightening conveyor of this utility model does not require manual tightening of bolts to adjust the swing of the driven roller shaft 11 for belt straightening. Instead, it uses the tensioning of the sliding tensioning seat 5 and the pushing of the first oil cylinder 15 to achieve the deflection and swing of the driven roller shaft 11, thereby achieving belt straightening of the transmission belt 2.
