A belt conveyor anti-deviation device

Abstract

This utility model discloses an anti-deviation device for a belt conveyor, comprising a frame, a rotating plate hinged to the upper left side of the frame, a drive motor fixedly installed on the upper left wall of the rotating plate, a drive shaft fixedly installed on the right wall of the drive motor, a sprocket fixedly installed through the left side of the drive shaft, and a chain meshing with the outside of the sprocket. This anti-deviation device for a belt conveyor detects the raw material using an infrared detection device. When the raw material deviates from the specified track, the drive motor is automatically started, driving two driven pulleys to rotate, which in turn drive two rotating rods to rotate, thereby driving a bevel gear set to rotate. The rotation of the bevel gear set drives a bidirectional lead screw to rotate, thereby driving the slider and connecting rod to move inward, so that the push plate adjusts the position of the raw material. After the work is completed, the rotating plate is rotated by starting a hydraulic cylinder, which facilitates cleaning of the equipment and reduces the labor burden of the user.

Description

Technical Field

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

[0002] A belt conveyor is a common material handling device, mainly used to transport materials from one location to another. It consists of a flexible conveyor belt, a drive system, rollers, etc. Belt conveyors are widely used in various industries such as mining, metallurgy, chemical industry, construction, food processing, and logistics, primarily for conveying bulk materials, finished product packages, granules, etc. By efficiently transporting materials, belt conveyors play a vital role in modern industry. However, existing anti-deviation devices for belt conveyors still have certain shortcomings; for example:

[0003] Application number CN202223410848.0, entitled "Anti-deviation device for a conveyor belt," includes a base. A support column is fixedly connected to the upper surface of the base. A support platform is fixedly connected to the upper surface of the support column. An installation groove is formed on the upper surface of the support platform. An anti-deviation device assembly is fixedly installed inside the installation groove. Auxiliary components are fixedly connected to both sides of the upper surface of the anti-deviation device assembly. A fixing component is fixedly connected to the upper surface of the support platform. Through the arrangement of the anti-deviation device assembly and auxiliary components, the conveyor belt will not deviate from the track when conveying items, preventing unnecessary deviations. The loss is due to the setting of fixed components and limit seats, which allows the conveyor belt to be restricted in position by the stop plate, thereby making the conveyor belt more stable when conveying items and increasing the safety of the device operation. As can be seen from the above, although the anti-deviation device of the belt conveyor can be used well, it cannot automatically adjust the material to return to the designated track according to the position of the material when conveying the material, which increases the labor burden of the user. After the material is conveyed, the belt cannot be cleaned, which makes it easy for the clean material to be dirty during the conveying process, resulting in a decrease in the quality of the material, which often troubles the user. Utility Model Content

[0004] The purpose of this utility model is to provide a belt conveyor anti-deviation device to solve the problems mentioned in the background art, such as the inability to automatically adjust the material back to the designated track according to the position of the material during material transportation, which increases the labor burden of users, and the inability to clean the conveyor belt after the material is transported, which makes it easy for the clean material to be soiled during the transportation process, resulting in a decrease in the quality of the material, which often troubles users.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a belt conveyor anti-deviation device, comprising a frame, a rotating plate hinged to the upper left side of the frame, a drive motor fixedly installed on the upper left wall of the rotating plate, a drive shaft fixedly installed on the right wall of the drive motor, a sprocket fixedly installed through the left side of the drive shaft, and a chain meshing with the outside of the sprocket, a spur gear fixedly installed through the middle section of the drive shaft, and a track meshing with the outside of the spur gear, two spring slide rods evenly fixedly installed on the upper right side of the frame, and a support frame slidably connected to the upper top surface of the rotating plate.

[0006] As a preferred embodiment of this utility model, the drive shaft, sprocket, and spur gear are symmetrically arranged about the center of the track. A drive motor is fixedly installed at the center of the upper top surface of the support frame, and a drive shaft is fixedly installed on the lower bottom surface of the drive motor. A double-headed pulley is fixedly installed through the lower end of the drive shaft, and a rotating rod is connected to a bearing embedded in the left side of the support frame.

[0007] As a preferred embodiment of this utility model, a driven pulley is fixedly installed through the upper end of the rotating rod, a bevel gear set is fixedly installed at the lower end of the rotating rod, a bidirectional lead screw is fixedly installed on the lower front wall of the bevel gear set, and a slider is threadedly connected to the front end of the bidirectional lead screw.

[0008] As a preferred embodiment of this utility model, the right end of the slider is hinged to a connecting rod, the right end of the connecting rod is hinged to a push plate, the slider and the connecting rod are symmetrically arranged about the center of the bidirectional lead screw, and the middle sections of the two connecting rods are hinged together, and the push plate is slidably connected to the track.

[0009] As a preferred technical solution of this utility model, the rotating rod, driven pulley, bevel gear set, double-acting screw, slider, connecting rod and push plate are symmetrically arranged about the center of the frame, and the two driven pulleys are staggered. An infrared detection device is fixedly installed at the center of the lower bottom surface of the support frame.

[0010] As a preferred embodiment of this utility model, a hydraulic cylinder is hinged to the right side of the inner top surface of the frame, the upper end of the hydraulic cylinder is hinged to the upper top surface of the rotating plate, and four support legs are evenly fixedly installed on the lower bottom surface of the frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This belt conveyor anti-deviation device detects the raw material using an infrared detection device. When the raw material deviates from the specified track, the drive motor is automatically started. The drive motor drives the rotation of two driven pulleys, which in turn drive the rotation of two rotating rods, thereby driving the rotation of a bevel gear set. The rotation of the bevel gear set drives the rotation of a bidirectional lead screw, which in turn drives the slider and connecting rod to move inward, thus adjusting the position of the push plate relative to the raw material. After the work is completed, the hydraulic cylinder is started to drive the rotating plate to rotate, which facilitates the cleaning of the equipment and reduces the labor burden of the user.

[0018] Please see Figure 1-4This utility model provides a technical solution: a belt conveyor anti-deviation device, comprising a frame 1, a rotating plate 2 hinged to the upper left side of the frame 1, a drive motor 3 fixedly installed on the upper left wall of the rotating plate 2, a drive shaft 4 fixedly installed on the right wall of the drive motor 3, a sprocket 5 fixedly installed through the left side of the drive shaft 4, and a chain 6 meshing with the outside of the sprocket 5, a spur gear 7 fixedly installed through the middle section of the drive shaft 4, and a track 8 meshing with the outside of the spur gear 7, two spring slide rods 9 evenly fixedly installed on the upper right side of the frame 1, and a support frame 10 slidably connected to the upper top surface of the rotating plate 2.

[0019] The drive shaft 4, sprocket 5 and spur gear 7 are arranged symmetrically about the center of the track 8. The drive motor 11 is fixedly installed at the center of the upper top surface of the support frame 10. The drive shaft 12 is fixedly installed on the lower bottom surface of the drive motor 11. The lower end of the drive shaft 12 is fixedly installed with a double-headed pulley 13. The left side of the support frame 10 is inlaid with a bearing and connected to a rotating rod 15.

[0020] A driven pulley 14 is fixedly installed through the upper end of the rotating rod 15, a bevel gear set 16 is fixedly installed at the lower end of the rotating rod 15, a double-acting screw 17 is fixedly installed on the lower front wall of the bevel gear set 16, and a slider 18 is threadedly connected to the front end of the double-acting screw 17.

[0021] The right end of the slider 18 is hinged to the connecting rod 19, and the right end of the connecting rod 19 is hinged to the push plate 20. The slider 18 and the connecting rod 19 are symmetrically arranged about the center of the two-way lead screw 17, and the middle sections of the two connecting rods 19 are hinged. The push plate 20 is slidably connected to the track 8.

[0022] The rotating rod 15, driven pulley 14, bevel gear set 16, double-acting screw 17, slider 18, connecting rod 19 and push plate 20 are arranged symmetrically about the center of frame 1, and the two driven pulleys 14 are staggered. An infrared detection device 21 is fixedly installed at the center of the lower bottom surface of the support frame 10.

[0023] A hydraulic cylinder 22 is hinged to the right side of the inner top surface of frame 1. The upper end of the hydraulic cylinder 22 is hinged to the upper top surface of the rotating plate 2. Four support legs 23 are evenly fixedly installed on the lower bottom surface of frame 1.

[0024] Working principle: When using a belt conveyor anti-deviation device, the user first places the raw material on the track 8, then starts the drive motor 3 to rotate and drive the track 8 to move, conveying the raw material. The infrared detection device 21 then detects the position of the raw material. When the raw material deviates from its designated path, the drive motor 11 automatically starts and rotates, driving the drive shaft 12 to rotate. The rotation of the drive shaft 12 drives the double-headed pulley 13 to rotate, which in turn drives the two driven pulleys 14 to rotate. This causes the rotating rod 15 to drive the bevel gear set 16 to rotate. 6 drives the bidirectional lead screw 17 to rotate. Through the meshing of the bidirectional lead screw 17 and the slider 18, the two connecting rods 19 are adjusted inward, thereby driving the push plate 20 to move inward and push the raw material back to the specified position. After the raw material is conveyed, the hydraulic cylinder 22 is activated to drive the rotating plate 2 to rotate, which facilitates the cleaning of the track 8. When the hydraulic cylinder 22 drives the rotating plate 2 to reset, the spring slide rod 9 can buffer the rotating plate 2, thereby completing a series of tasks.
