Description

Technical Field

[0001] The invention belongs to the field of belt conveyor supporting equipment, and in particular relates to an over-long conveyor belt bypass processing and retracting device and an operating method thereof. Background Art

[0002] Belt conveyor, also known as rubber belt conveyor, is an economical logistics conveying equipment that is indispensable for rhythmic assembly line. Belt conveyor is mainly composed of two end rollers and a closed conveyor belt tightly sleeved on them. The driving roller is driven by an electric motor through a reducer. The conveyor belt is dragged by the friction between the driving roller and the conveyor belt, which is convenient for programmed control and automatic operation.

[0003] Nylon conveyor belt refers to the middle interlayer canvas is nylon canvas. Nylon conveyor belt has the characteristics of thin belt body, high strength, impact resistance, good troughing, strong interlayer adhesion, excellent flexibility and long service life. It is widely used in mines, coal yards, chemicals, metallurgy, construction, ports and other departments.

[0004] Nylon conveyor belt care and maintenance: 1) During transportation and storage, the conveyor belt should be kept clean and avoid direct sunlight or rain and snow, prevent contact with acids, alkalis, oils, organic solvents and other substances, and be one meter away from heating devices. 2) During storage, the warehouse temperature should be maintained between -18-40°C, and the relative humidity should be maintained between 50-80%. 3) During storage, the product must be placed in a roll and must not be folded. When using a nylon conveyor belt, it is necessary to connect the ends to form a closed tape loop after winding around the rollers at both ends of the conveyor. The bonding methods of nylon conveyor belts mainly include cold vulcanization bonding and hot vulcanization bonding.

[0005] The Chinese invention patent with application number 202323557705.7 discloses a belt conveyor belt winding device, including a belt winding mechanism, the belt winding mechanism includes a fixed frame, the fixed frame includes side brackets arranged on both sides, and belt winding rotors are installed on the side brackets. At least one of the two belt winding rotors is connected to the belt winding motor in a transmission manner. A belt winding bar is detachably connected between the two belt winding rotors. Two belt winding fixing disks are installed on the belt winding bar, at least one of the belt winding fixing disks is detachably connected to the belt winding bar, and can be adjusted and fixed at different positions in the length direction of the belt winding bar.

[0006] The winding mechanism of the existing conveyor tape winding device is generally used to complete the winding of tapes with a length of less than 150 meters. For the winding operation of super-long tapes (more than 300 meters, or even more than 600 meters), the tape roll is very likely to have stacking deviations in the space exceeding the height of the side plate of the winding mechanism, resulting in deformation and damage of the tape, or even collapse after being wound to a certain height, making it impossible to complete the winding. In addition, due to the large weight of the tape itself, the rotational inertia of the tape will cause the winding and unwinding speed of the tape roll to be out of control during the winding and unwinding process, posing a safety hazard and disrupting the normal production order. The existing super-long conveyor tape requires multiple 150-meter standard length tapes to be connected on site one by one when the tape is replaced, and then vulcanized one by one. The conveyor downtime is very long (generally, it takes about a week to change the tape once), which greatly affects production efficiency. Summary of the invention
