Abstract

This utility model relates to a self-balancing anti-deviation conveyor, comprising a frame and a conveyor belt mounted on top of the frame. Guide wheels are located below the conveyor belt, and a guide drive unit is also located below the conveyor belt. The guide drive unit rotates as the conveyor belt deviates, driving the guide wheels to rotate in the opposite direction to the conveyor belt's deviation. By placing guide wheels at the bottom of the conveyor belt, the guide wheels rotate in the opposite direction to the conveyor belt's deviation, providing a guiding force to return the conveyor belt to its normal position. This design provides good self-balancing and anti-deviation effects when dealing with minor deviations caused by uneven material loading.

Description

Technical Field

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

[0002] Conveyors are mechanical equipment used to transport materials. According to their operation mode, they can be divided into belt conveyors, screw conveyors, bucket elevators, roller conveyors, etc. Among them, belt conveyors are the most widely used type of conveyor in various industries. They can be used to transport packaged materials as well as bulk materials.

[0003] Belt conveyors may experience belt misalignment during actual use. This can be caused by several factors, including the misalignment of the drive roller axis with the conveyor's centerline. The distribution of goods on the conveyor belt also affects its conveying performance. When materials are biased to one side of the belt, the uneven pressure exerted by the material's center of gravity on the belt causes misalignment. In this case, adjusting the drive roller angle is not necessary, but prolonged misalignment can cause wear and tear on the conveyor belt. Solving this misalignment problem would be beneficial for the protection of the equipment. Summary of the Invention

[0004] This utility model is a self-balancing anti-deviation conveyor. It has a guide wheel at the bottom of the conveyor belt. The guide wheel rotates in the opposite direction according to the deviation of the conveyor belt, giving the conveyor belt a certain guiding force and making the conveyor belt return to the normal state. It can achieve a good self-balancing anti-deviation effect when dealing with slight deviation caused by uneven material loading.

[0005] The present invention adopts the following technical solution:

It should be understood that the following embodiments are only one or more manifestations of the present invention and are not a complete limitation on the invention content recorded in this application. Any improvements made based on the invention content or technical solution recorded in this application that are known to those skilled in the art should fall within the scope of protection claimed in this application.

[0019] Furthermore, the descriptions of directions such as up, down, left, right, front, and back presented in the specific embodiments are merely for the purpose of describing the technical solutions and are not absolute limitations unless otherwise stated.

[0020] like Figures 1-4 The self-balancing anti-deviation conveyor shown includes a frame 1 and a conveyor belt 2 located on top of the frame 1. A guide wheel 3 is provided below the conveyor belt 2, and a guide drive unit 4 is also provided below the conveyor belt 2. The guide drive unit 4 rotates as the conveyor belt 2 deviates, and the rotation of the guide drive unit 4 drives the guide wheel 3 to rotate in the opposite direction to the deviation direction of the conveyor belt 2.

[0021] The conveyor belt 2 is generally in the form of a ring structure. The top of the frame 1 is provided with a drive roller 101 and a support roller 102. The conveyor belt 2 is wrapped around the outside of the drive roller 101 and the support roller 102. The guide wheel 3 is located between the ring conveyor belt 2 and is attached to the upper inner wall of the conveyor belt 2.

[0022] The frame 1 is provided with a transverse bracket 103, which passes through the conveyor belts 2. A rotating guide wheel compartment 301 is provided above the bracket 103. The guide wheel compartment 301 is provided with evenly distributed axles 302. Multiple guide wheels 3 are evenly distributed on the axles 302. The guide wheels 3 are aligned with the conveying direction of the conveyor belts 2. A guide rod 303 is provided at the rear of the guide wheel compartment 301.

[0023] The guide drive unit 4 includes a guide frame 401 and a transverse frame 402. The guide frame 401 is mounted on the frame 1 below the conveyor belt 2. The transverse frame 402 corresponds to the tail of the guide rod 303. The transverse frame 402 has a ring structure. The lower half of the conveyor belt 2 passes through the transverse frame 402. The guide frame 401 corresponds to the bottom of the transverse frame 402, and the guide rod 303 corresponds to the top of the transverse frame 402.

[0024] A slide rail 104 is provided on the frame 1 at a position corresponding to the transverse frame 402, and the transverse frame 402 slides within the slide rail 104; a limiting post 304 is provided below the tail of the guide rod 303, and a horizontally arranged strip-shaped sliding hole 403 is provided on the top of the transverse frame 402, and the limiting post 304 is guided and driven through the sliding hole 403.

[0025] The guide frame 401 is generally X-shaped. The center of the guide frame 401 is hinged above the frame 1. Vertical sliding columns 404 are provided at the four corners of the guide frame 401. The inner side of the sliding column 404 is attached to both sides of the conveyor belt 2. The front part of the guide frame 401 is provided with a forward-extending connecting rod 405. The front end of the connecting rod 405 is hinged to the bottom center of the transverse frame 402.

[0026] When the conveyor belt deviates during use, the conveyor belt drives the sliding column, causing the guide frame to deflect on the frame in the direction of the conveyor belt deviation. The deflection of the guide frame drives the connecting rod to rotate, which in turn causes the transverse frame to move laterally. The movement of the transverse frame causes the tail of the guide rod to move, causing the guide wheel to deflect in the opposite direction. After the deflection, the guide wheel guides the conveyor belt in the opposite direction of deviation, bringing it back to its normal state.

[0027] This device guides the conveyor belt back to its normal state in the event of uneven load distribution, and can achieve a self-balancing anti-deviation effect in actual use.
