Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyor belt joint technology, specifically a high-strength connection structure for preventing loosening of conveyor belts. Background Technology
[0002] In today's industrial production and logistics transportation, conveyor belts play a crucial role. They are widely used in many scenarios such as mining, port loading and unloading, and factory assembly lines, undertaking the important task of continuously and efficiently transporting various materials. On the one hand, the types of materials transported are becoming increasingly complex, including not only conventional block ores and coal, but also some corrosive chemical raw materials, as well as irregularly shaped, hard metal scraps that can easily impact the conveyor belt. Conveyor belts are characterized by thin belts, light weight, low drive power, good troughing properties, high production efficiency, and low cost.
[0003] With the continuous development of industry, the requirements for conveyor belt performance are becoming increasingly stringent. However, existing conveyor belt connection structures are unable to meet these new demands. Traditional connection methods, such as mechanical snap-fit connections, are relatively convenient to install, but when faced with the impact of heavy materials, the snaps are prone to loosening and deformation, resulting in a sharp drop in the strength of the conveyor belt connection and frequent breakage failures, which greatly affects production efficiency. The connection convenience of the joint is also insufficient, and the strength of direct vulcanization bonding is low, affecting the normal service life and operating performance of the conveyor belt. To address these issues, we propose a high-strength, anti-loosening connection structure for conveyor belts. Utility Model Content

This solves the problem that conveyor belt joints are usually connected by punching and buckling, which reduces tensile strength and service life.
