Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically to a conveyor belt anti-deviation device. Background Technology

[0002] Belt conveyors, also known as conveyor belts, are characterized by their high conveying capacity, long conveying distance, simple structure, ease of maintenance, and convenient programmable control and automated operation. They utilize the continuous or intermittent movement of the conveyor belt to transport items weighing less than 100 kg or powdery or granular materials. They operate at high speeds, smoothly, and with low noise, and can transport items uphill and downhill.

[0003] Currently, after a period of use, conveyor belts may age and deform, leading to a decrease in their elasticity, reduced tension, and belt loosening, which in turn causes belt misalignment. When the conveyor belt misaligns, it can cause excessive friction or even tearing of the conveyor belt edges, and in severe cases, it can even damage components such as rollers and idlers. Utility Model Content

[0004] The purpose of this invention is to provide a conveyor belt anti-deviation device to solve the problem of conveyor belts going off-track after prolonged use.

[0006] Preferably, both the fixed correcting roller and the movable correcting roller are composed of a roller body and a guide plate, with the roller body mounted on one end of the guide plate, and the guide plate being circular.

[0007] Preferably, L-shaped plates are symmetrically installed at the front and rear of one end of the fixed plate below the fixed correction roller, and the moving block is T-shaped and is slidably installed between the two L-shaped plates.

[0008] Preferably, a movable groove is provided through one end of the fixed plate, and the lifting plate is located inside the movable groove.

[0009] Preferably, the pressure detection assembly includes guide rods, springs, pressure sensors, and a controller. Four guide rods are mounted in a rectangular array on the upper end of the lifting plate. The upper ends of the four guide rods all pass through the connecting plate via through holes. Springs are installed on the surfaces of the guide rods between the connecting plate and the lifting plate. A pressure sensor is installed on the upper end of the lifting plate between the four guide rods. A controller is installed on the upper end of the mounting plate.

[0010] Preferably, a clamping plate is installed below the mounting plate, and the mounting plate and the clamping plate are connected by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This conveyor belt anti-deviation device corrects and guides the upper and lower conveyor belts by setting fixed and movable correcting rollers, and uses an electric push rod to adjust the distance between the fixed and movable correcting rollers. It is suitable for correcting the deviation of various types of conveyor belts and effectively prevents the conveyor belt from being damaged due to deviation.

[0013] This conveyor belt anti-deviation device, through the installation of a pressure detection component, ensures that when the electric push rod drives the movable correcting roller to move, the movable correcting roller contacts the conveyor belt. The movable correcting roller, via the moving block and lifting plate, drives the guide rod to move upward.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, a conveyor belt anti-deviation device includes a conveyor belt body 1 and a conveyor belt frame 2. The conveyor belt body 1 is located inside the conveyor belt frame 2. An mounting plate 3 is installed on the conveyor belt frame 2. A fixing plate 4 is installed on one side of the lower end of the mounting plate 3. A fixed correction roller 5 is rotatably mounted on one end of the fixing plate 4 via a rotating shaft. The fixed correction roller 5 is used to contact the upper conveyor belt body 1. A movable block 6 is movably installed below the fixed correction roller 5. A movable correction roller 7 is rotatably mounted on one end of the movable block 6 via a rotating shaft. The movable block 6 can drive the movable correction roller 7 to rise and fall, and can adjust the distance between the fixed correction roller 5 and the movable correction roller 7. It is suitable for various types of conveyor belts. A lifting plate 8 is installed on the other end of the movable block 6. An electric push rod 9 is installed on the lower end of the mounting plate 3 on one side of the fixing plate 4. When the electric push rod 9 rises and falls, it drives the movable correction roller 7 to rise and fall through the lifting plate 8. A connecting plate 10 is installed at the output end of the electric push rod 9. A pressure detection component is installed between the connecting plate 10 and the lifting plate 8. The pressure detection component is used to detect the contact pressure between the movable correction roller 7 and the lower conveyor belt body 1.

[0021] Specifically, both the fixed correction roller 5 and the movable correction roller 7 are composed of a roller body 12 and a guide plate 13. The roller body 12 is installed at one end of the guide plate 13, which is circular. When the conveyor belt body 1 rotates, it drives the roller body 12 to rotate. The guide plate 13 plays a limiting role at both ends of the conveyor belt body 1, preventing the conveyor belt body 1 from rotating off-center.

[0022] Furthermore, L-shaped plates 14 are symmetrically installed at the front and rear of one end of the fixed plate 4 below the fixed correction roller 5. The moving block 6 is T-shaped and is slidably installed between the two L-shaped plates 14. The L-shaped plates 14 play a guiding role in the movement of the moving block 6.

[0023] Furthermore, a movable groove 15 is provided through one end of the fixed plate 4, and the lifting plate 8 is located inside the movable groove 15. The movable groove 15 provides space for the lifting plate 8 to rise and fall, and at the same time plays a guiding role in the movement of the lifting plate 8.

[0024] Furthermore, the pressure detection assembly includes guide rods 1101, springs 1102, pressure sensors 1103, and controllers 1104. Four guide rods 1101 are mounted in a rectangular array on the upper end of the lifting plate 8. The upper ends of all four guide rods 1101 pass through the connecting plate 10 via through holes. Springs 1102 are installed on the surfaces of the guide rods 1101 between the connecting plate 10 and the lifting plate 8. A pressure sensor 1103 is installed on the upper end of the lifting plate 8 between the four guide rods 1101. A controller 1104 is installed on the upper end of the mounting plate 3. When the electric push rod 9 drives the movable correcting roller 7 to move downwards, the movable correcting roller 7 contacts the lower conveyor belt body 1 with a certain pressure. The correcting roller 7 moves the guide rod 1101 upward via the moving block 6 and the lifting plate 8. At the same time, the lifting plate 8 compresses the elastic spring 1102. The pressure sensor 1103 contacts the connecting plate 10. The pressure sensor 1103 detects the contact pressure between the movable correcting roller 7 and the conveyor belt body 1 and transmits the data to the controller 1104. The controller 1104 controls the electric push rod 9 to perform real-time action, so that the conveyor belt body 1 can always maintain a suitable tension for rotation, realizing automatic adjustment. The pressure sensor 1103 is a piezoelectric pressure sensor (such as: POx7 triaxial force sensor). The specific working principle of the piezoelectric sensor is known existing technology, so it will not be described in detail.

[0025] Furthermore, a clamping plate 16 is installed below the mounting plate 3. The mounting plate 3 and the clamping plate 16 are connected by bolts and are used together to install the mounting plate 3 and the clamping plate 16 on the conveyor belt frame 2.

[0026] The usage method of this embodiment is as follows: First, there can be multiple devices. The mounting plate 3 and the clamping plate 16 cooperate to clamp the conveyor belt frame 2, so that the fixed correcting roller 5 contacts the upper conveyor belt. Then, the electric push rod 9 is controlled to extend. The extension of the electric push rod 9 drives the movable correcting roller 7 to contact the lower conveyor belt. During this process, the movable correcting roller 7 contacts the lower conveyor belt body 1 with a certain pressure. The movable correcting roller 7 drives the guide rod 1101 to move upward through the moving block 6 and the lifting plate 8. At the same time, the lifting plate 8 compresses the elastic spring 1102. The pressure sensor 1103 contacts the connecting plate 10. The pressure sensor 1103 detects the contact pressure between the movable correcting roller 7 and the conveyor belt body 1 and transmits the data to the controller 1104. The controller 1104 controls the electric push rod 9 to perform real-time action, so that the conveyor belt body 1 can always maintain a suitable tension for rotation, so that the conveyor belt can maintain tension and avoid the conveyor belt from running off-center due to insufficient tension.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
