Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically an automatic self-aligning support for belt conveyors. Background Technology

[0002] Belt conveyors, also known as belt conveyors or rubber belt conveyors, are continuous conveying equipment widely used in industrial production. They mainly consist of a frame, conveyor belt, idlers, rollers, tensioning devices, and transmission devices. Belt conveyors transport materials along a specific conveying line from the initial feeding point to the final unloading point, forming a material conveying process. To improve the operational stability and production efficiency of belt conveyors, an automatic self-aligning support system is required.

[0003] In the existing technology, belt conveyors often run off-track during use. This running off-track can lead to abnormal wear between the various components of the belt conveyor, causing frequent belt conveyor failures. It can also cause the materials being transported by the belt to deviate and fall off. To correct the running off-track, it is usually necessary to stop the machine and make manual adjustments, which reduces work efficiency and affects production progress.

[0004] To address these issues, this invention provides an automatic self-aligning support for belt conveyors. Utility Model Content

The front side of the servo motor is fixedly connected to the rear side of the rear support frame, and the front side of the fixed base is fixedly connected to the rear side of the rear support frame. A cam is fixedly connected to the output end of the servo motor. Slider blocks are slidably connected to both outer sides of the fixed base. A push block is fixedly connected between the two sliders. A roller is rotatably connected to the rear side of the push block. A moving rod is fixedly connected to the front side of the push block. A brush is fixedly connected to the front side of the moving rod. A spring is sleeved on the outer side of the moving rod.

[0014] Beneficial effects

[0015] This utility model provides an automatic self-aligning support for a belt conveyor. Compared with the prior art, it has the following advantages:

[0016] (1) The automatic self-aligning bracket for belt conveyors drives the conveyor roller to rotate via a motor, and at the same time drives the turntable to rotate via the transmission roller. The turntable drives the connecting rod, and the connecting rod and the connecting rod work together to pull the rack back and forth. Then the transmission gear rotates, and at the same time drives the bidirectional threaded rod to rotate, so that the threaded sleeves at both ends move towards the middle. Then, the connecting bracket drives the mounting plate and guide wheel to move, thereby limiting the conveyor belt, avoiding deviation, and improving the overall work efficiency.

[0017] (2) The automatic self-aligning bracket for belt conveyors drives the cam to rotate by starting the servo motor. The cam intermittently pushes the roller, the roller drives the push block, the push block drives the slider to slide inside the fixed seat, and then pushes the moving rod. The moving rod pushes the brush. When the brush moves, it cleans the transmission belt and compresses the spring, thus realizing automatic cleaning of the conveyor belt and improving the practicality of the device.
