Description

Technical Field

[0001] The utility model relates to the field of conveyor belts, in particular to a conveyor belt mechanism. Background Art

[0002] Conveyor belts are a vital piece of conveying equipment. They serve as the carrier medium of a conveyor system and consist of one or more endless belts, typically made of materials such as rubber, plastic, and metal. These belts are mounted between two or more rollers to form a continuous conveyor line. Conveyor belts can be categorized into various types, depending on their material and intended use, such as rubber, plastic, and metal. Each type of belt offers distinct characteristics, such as wear and corrosion resistance from rubber belts, lightweight and easy-to-clean plastic belts, and high strength and load-bearing capacity from metal belts. Furthermore, depending on the application, conveyor belts can be customized with various patterns and thicknesses to meet diverse conveying and safety requirements. Conveyor belts typically consist of one or more layers of material. Tension is typically provided by industrial polyester fabric, while coatings may be made of materials such as PVC, PU, PE, and SIR to ensure stability and mechanical performance. Conveyor belts have a wide range of applications, covering nearly every industry requiring material transportation. In industrial production, conveyor belts are used to transport raw materials, transport semi-finished and finished products during production, and dispose of waste.

[0003] The operating principles of a conveyor belt are based on power transmission, motion control, and object handling. It primarily consists of a conveyor belt, a drive unit, a tensioning device, rollers, a support frame, and safety devices. The drive unit, typically consisting of a motor, a reducer, and bearings, provides power to the conveyor belt. The tensioning device adjusts the belt's tightness to ensure proper operation. Rollers support and guide the conveyor belt, while the support frame secures it. Safety devices ensure safety during transportation.

[0004] The conveyor belt mechanism on the bag unscrambler is equipped with sensors such as photoelectric sensors, weight sensors, and visual recognition systems. These sensors detect key parameters such as product size, weight, and appearance, and compare them with preset standard values. The sensors transmit the detected data to the control system, which processes and analyzes the data. Existing conveyor belt mechanisms are often equipped with mechanical devices for waste removal, such as pneumatic push rods, electric slides, and robotic arms, to separate defective products from the main production line. These devices are complex, difficult to maintain, and prone to failure. Utility Model Content
