Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt conveyor technology, and in particular to a reversible anti-deviation belt conveyor. Background Technology
[0002] Belt conveyors, also known as belt conveyors, are a type of high-efficiency continuous conveying equipment. The conveyor belt acts like a transportation "artery," continuously operating under the drive mechanism. It can stably and efficiently transport various bulk materials or packaged goods from one location to another. With its advantages such as large conveying capacity, stable operation, long conveying distance, simple operation, and convenient maintenance, belt conveyors are widely used in many industries such as mining, ports, factories, and logistics. They greatly improve material handling efficiency and reduce labor costs, making them an indispensable and important piece of equipment in modern industrial production and logistics transportation.
[0003] However, most existing belt conveyors are unable to effectively prevent belt misalignment, often resulting in uneven driving force at both ends. This leads to belt imbalance and misalignment, making it difficult to adjust belt tension accurately in real time according to complex working conditions. Consequently, the belt tension varies erratically under different loads, seriously affecting the stability of material conveying and causing frequent material spillage and blockages during the conveying process. Utility Model Content
[0004] The purpose of this invention is to solve the problem that most existing belt conveyors are unable to effectively prevent belt misalignment, often resulting in uneven driving forces at both ends, leading to belt imbalance and misalignment. Consequently, it is difficult to adjust the belt tension accurately in real time according to complex working conditions, causing the belt tension to change erratically under different loads, which seriously affects the stability of material conveying and causes frequent material spillage and blockage during the conveying process. Therefore, a reversible anti-misalignment belt conveyor is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a reversible anti-deviation belt conveyor, comprising an intermediate frame, a first leg and a second leg fixedly connected to the lower surface of the intermediate frame, a plow-type unloader fixedly installed on the upper surface of the intermediate frame, a head funnel installed at one end of the intermediate frame near the plow-type unloader, a drive roller installed on one side of the head funnel, a cleaner fixedly installed at one end of the intermediate frame near the drive roller, a head frame fixedly installed at one end of the intermediate frame near the cleaner, a redirecting roller installed on the lower surface of the head frame, and a tape installed at one end of the intermediate frame near the redirecting roller, the tape being sleeved with the redirecting roller.
[0006] Preferably, guardrails are fixedly connected to both ends of the intermediate frame, and the guardrails are respectively set on both sides of the intermediate frame.
[0007] Preferably, a tensioning device is fixedly connected to the lower surface of the intermediate frame, and a friction self-aligning idler roller is installed on the side of the intermediate frame near the tensioning device. By setting the tensioning device and adopting a bidirectional tensioning design, the tension can be adjusted bidirectionally according to the actual situation to ensure that the belt tension is appropriate.
[0008] Preferably, a bidirectional pull rope switch is installed on the side of the intermediate frame near the friction self-aligning idler, and a parallel lower idler is installed at the end of the intermediate frame near the bidirectional pull rope switch. By setting the parallel lower idler, it is mainly used to support the return belt, so that the belt maintains a certain shape and position during operation, prevents the belt from sagging excessively due to its own weight and the weight of the material, and ensures that the belt can run smoothly on the predetermined track.
[0009] Preferably, a friction upper self-aligning roller is rotatably mounted on one end of the intermediate frame near the parallel lower roller, and a grooved roller is rotatably mounted on the side of the intermediate frame near the friction upper self-aligning roller.
[0010] Preferably, a two-stage deviation switch is installed at one end of the intermediate frame near the trough-shaped idler roller, and there are multiple first and second legs, all of which are located below the intermediate frame.
[0011] Preferably, the inner wall of the intermediate frame is equipped with a drive mechanism. There are two drive mechanisms, which are symmetrically arranged. The drive end of the drive mechanism is sleeved with the belt. By setting the drive mechanism, the head and tail dual drive structure ensures that the belt can be provided with uniform and stable driving force in both forward and reverse conveying. This solves the problem of the belt being loose at the top and tight at the bottom and prone to deviation when conveying in reverse, and keeps the working surface in a taut state at all times.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] In this invention, during operation, the drive mechanism works simultaneously to provide power for the conveyor belt to circulate, thereby achieving material conveying. The dual-drive structure at both the head and tail ensures a uniform and stable driving force for the belt during both forward and reverse conveying, solving the problem of belt slippage during reverse conveying due to looseness at the top and tightness at the bottom. This keeps the working surface taut at all times. The plow-type unloader unloads material from the conveyor belt, the head funnel collects and guides the material, the drive roller transmits power to drive the conveyor belt, the cleaner removes residual material from the belt, and the tensioning device, located at the return belt, employs a bidirectional tensioning design, allowing for bidirectional adjustment of the tension according to actual conditions to ensure proper belt tension and further prevent belt slippage. Various idlers, such as friction self-aligning idlers and friction rollers, are also included. Self-aligning idlers, trough idlers, and parallel lower idlers support and guide the belt's movement. They automatically adjust when the belt tends to deviate. Two-stage deviation switches and bidirectional pull rope switches serve as safety protection devices, which can be triggered in time to stop the equipment in case of severe belt deviation or emergency, ensuring stable material transport throughout the entire process. By incorporating this invention, the continuity and stability of material transport are greatly guaranteed. Regardless of the complex working conditions, it can efficiently meet the material transport needs, significantly improving transport efficiency. At the same time, it keeps the belt in optimal working condition at all times, effectively preventing deviation caused by improper tension and greatly extending the belt's service life, reducing downtime and high costs caused by frequent belt replacements.

[0027] Specifically, the inner wall of the intermediate frame 1 is equipped with a drive mechanism 16. There are two drive mechanisms 16, which are arranged symmetrically. The drive end of the drive mechanism 16 is sleeved with the tape 9.
[0028] Working principle: During operation, the drive mechanism 16 simultaneously provides power to make the conveyor belt 9 circulate, thereby realizing material conveying.

No matter what complex working conditions, it can efficiently meet the material transportation needs and significantly improve the conveying efficiency.
