Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor belt correction equipment, and more specifically, to a belt correction device for belt conveyor transportation. Background Technology

[0002] A belt conveyor is a continuous conveying machine that uses a flexible conveyor belt as the material carrying and traction component. The material is placed on the upper branch, and the friction between the drive drum and the belt is used to traction the conveyor belt and the material. It is suitable for conveying bulk materials and packaged goods in horizontal and inclined directions, and can also be used in assembly lines for certain process operations. During operation, factors such as material drop point deviation, improper component installation, inflexible idler roller operation, uneven drum wear, and material remaining between the drum and the belt can cause belt deviation, requiring the use of a belt correction device to correct the belt deviation.

[0003] The existing belt alignment devices have the following problems in actual use: First, each idler support of the belt conveyor is designed with an independent alignment device, and the adjacent idler supports are not linked. However, belt deviation is a continuous process from top to bottom. The independent adjustment angles and positions of each independent alignment device are independent and unrelated, which cannot achieve a good alignment effect. Second, the existing alignment devices directly adjust the angles of the three idlers above each idler support (left, center, and right) for alignment, which actually changes the preset idler angle position. After the alignment is completed, it is necessary to manually adjust back to the initial position. On the one hand, the reset accuracy cannot be guaranteed, and on the other hand, the operation is cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a belt conveyor correction device. This correction device uses a linkage rod to connect all correction components from top to bottom, resulting in good overall adjustment consistency. Each correction component can be reasonably adjusted according to its own position, resulting in a good correction effect. At the same time, the correction device is independent of each idler bracket and can be directly retracted after correction without changing the position of the idler, making the operation simple and quick.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A belt-aligning device for conveyor belt transportation includes a frame arranged parallel to both sides, with several idler roller supports installed at equal intervals between the frames. Each idler roller support is provided with three idlers (left, center, and right). The upper surface of the frame arranged parallel to both sides is provided with a double-layer alignment support. Several support plates are provided at equal intervals between the double-layer alignment supports. A through groove is opened on both sides of the double-layer alignment support, and a support column passes through the through groove. Limiting baffles are fixed on the left and right sides of the support column. A piston rod of an electrically controlled cylinder is fixedly connected to the lower surface of the support column. Several L-shaped push rods are installed at intervals on the inner side of the double-layer alignment support through threaded connecting pieces. A rotating bearing seat is installed at the outer end of the vertical section of each L-shaped push rod. A double-layer alignment roller is rotatably connected to the rotating part of the rotating bearing seat. The double-layer alignment roller extends into the area between adjacent left and right idlers through the L-shaped push rods.

[0007] As a further optimization of this solution, several inverted concave connecting rods are fixedly installed on the upper outer edge of the double-layer correction bracket by several concave clamps. The concave clamps are fixed to the edge of the double-layer correction bracket by screws on the outer side. An ultrasonic distance sensor is fixedly installed on the outer end of the inverted concave connecting rod by a sleeve. The probe of the ultrasonic distance sensor is located above the outer end of the left and right idler rollers on both sides.

[0008] As a further optimization of this solution, one of the racks arranged in parallel on both sides has a control box and a hub on its upper surface, and the other rack has a hub on its upper surface. The hub connects the wiring of all ultrasonic distance sensors and electric cylinders on that side. The hub is connected to the control box via wiring, and the control box is connected to the factory's power supply.

[0009] As a further optimization of this solution, the vertical section of the L-shaped top rod is inclined and the inclination angle is the same as that of the left and right side rollers.

[0010] As a further optimization of this solution, the width of the through groove is greater than the diameter of the support column.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a double-layered belt-correcting support structure with adjustable tilt angle and height, combined with a double-layered belt-correcting roller structure located between adjacent left and right idlers. This enables belt-correcting operations on conveyor belts. Several ultrasonic distance sensors located above the outer ends of the left and right idlers detect belt deviation. When one side of the conveyor belt deviates, the control unit activates the electrically controlled cylinders at both ends of that side, tilting and lifting the double-layered belt-correcting support on that side. The double-layered belt-correcting rollers then support the conveyor belt inward for correction. The overall adjustment consistency is good, and each correction component can be adjusted at a reasonable angle according to its position, resulting in a good correction effect. Furthermore, this correction device is independent of each idler support and can be retracted directly by the electrically controlled cylinder after correction, without changing the idler position, making the operation simple and quick.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0019] To address the issues that existing belt conveyors have independent correction devices at each idler bracket, and that adjacent idler brackets are not linked, while belt misalignment is a continuous process from top to bottom, the independent correction devices adjust angles and positions independently and unrelatedly, which cannot achieve good correction results. Furthermore, the existing correction devices directly adjust the angles of the three idlers above each idler bracket (left, center, and right) for correction, which actually changes the preset idler angle positions. After correction, manual adjustment back to the initial position is required, which not only fails to guarantee reset accuracy but also makes the operation cumbersome.

[0020] like Figure 1 As shown, this application includes a frame 1 arranged in parallel on both sides and a plurality of roller brackets 2 installed at equal intervals between the frame 1. Each roller bracket 2 is assumed to have three rollers 3 on the left, middle and right. The upper surface of the frame 1 arranged in parallel on both sides is provided with double-layer correction brackets 7. A plurality of support plates 8 are provided at equal intervals between the double-layer correction brackets 7.

[0021] like Figure 2 As shown, the double-layer correction bracket 7 has through slots on both sides and the support column 9 passes through the through slots. Limiting baffles 10 are fixed on both sides of the support column 9. The piston rod of the electric control cylinder 11 is fixedly connected to the lower surface of the support column 9. Several L-shaped top rods 13 are installed at intervals on the inner side of the double-layer correction bracket 7 through threaded connecting pieces 12. A rotating bearing seat is installed at the outer end of the vertical section of each L-shaped top rod 13. A double-layer correction roller 14 is rotatably connected to the rotating part of the rotating bearing seat. The double-layer correction roller 14 extends into the area between the adjacent left and right support rollers 3 through the L-shaped top rod 13.

[0022] Several inverted concave connecting rods 16 are fixedly installed on the upper outer edge of the double-layer correction bracket 7 through several concave clamps 15. The concave clamps 15 are fixed to the edge of the double-layer correction bracket 7 by screws on the outer side. An ultrasonic distance sensor 17 is fixedly installed on the outer end of the inverted concave connecting rod 16 through a clamp. The probe of the ultrasonic distance sensor 17 is located above the outer end of the left and right rollers 3 on both sides.

[0023] like Figure 3 As shown, one side of the rack 1, which is arranged in parallel on both sides, has a control box 4 and a hub 5 on its upper surface, and the other side of the rack 1 has a hub 5 on its upper surface. The hub 5 connects the lines 6 of all the ultrasonic distance sensors 17 and the electric cylinder 11 on that side. The hub 5 is connected to the control box 4 through the lines 6. The control box 4 is connected to the power supply of the factory area.

[0024] Specifically, the vertical section of the L-shaped top rod 13 is inclined at the same angle as the left and right side rollers 3, and the width of the through groove is greater than the diameter of the support column 9, such as... Figure 4As shown, when the conveyor belt above the idler roller 3 on one side deviates, simulated parameters are input in advance through the control panel of the control box 4. The control box 4 controls the electric cylinders 11 at both ends of that side to work, tilting and lifting the double-layer correction bracket 7 on that side. During the process, the support column 9 moves left and right between the through grooves. The double-layer correction rollers 14, which are tilted and lifted upwards, support the conveyor belt on that side inwards to correct the deviation. During the process, each double-layer correction roller 14 on the double-layer correction bracket 7 is linked through the double-layer correction bracket 7, so that the double-layer correction at each position is achieved. The tilt angle of the roller 14 decreases sequentially along the straight line of the double-layer correction bracket 7, conforming to the misalignment of the conveyor belt from front to back. The overall adjustment consistency is good. Each correction component can make reasonable angle adjustments according to its own position, resulting in a good correction effect. At the same time, the double-layer correction bracket 7 of this correction device is independent of each idler roller 3 bracket. After the correction is completed, the piston rod of the electric cylinder 11 of the control box 4 is lowered directly, so that the double-layer correction bracket 7 returns to the initial position without changing the position of the idler roller 3. The operation is relatively simple and quick.
