Mechanism preventing middle portion of bearing surface of flat belt conveyer from deviating

Abstract

The invention discloses a mechanism preventing middle portion of the bearing surface of a flat belt conveyer from deviating. The mechanism is arranged on the bearing surface (11) and comprises a machine frame (8) and a conveying belt (1). The machine frame is provided with a first belt pressing cylinder (2), a second belt pressing cylinder (3), a third belt pressing cylinder (4) and a tension cylinder (7). The first belt pressing cylinder and the second belt pressing cylinder are located above the third belt pressing cylinder and the tension cylinder, the conveying belt sequentially passes the first belt pressing cylinder, the second belt pressing cylinder, the third belt pressing cylinder and the tension cylinder, and a tensioning and deviation correcting device is further disposed on the machine frame between the third belt pressing cylinder and the tension cylinder. The tensioning and deviation correcting device is arranged on the bearing surface of the conveying belt in the middle of the belt conveyer, so that transverse friction of the conveying belt and the cylinders is increased, the conveying belt can not be influenced of conveying belt deviation caused by inclined upward loading impact during operation, deviation can be corrected at any time, and accordingly the aim that materials operate normally on the belt conveyer is achieved.

Description

technical field [0001] The invention relates to the field of belt conveyors, in particular to a mechanism for preventing deviation in the middle of the bearing surface of a flat belt conveyor. Background technique [0002] Belt conveyor is currently the most common material conveying method in the logistics transportation industry. The speed of the belt conveyor is stable, and the material is not easy to slip and shift during the conveying process. In the middle and high speed sorting and conveying, the positioning is accurate and reliable, and it is not affected by the shape and size of the material. , weight limit, wide applicability, and can be inclined ≤ 15 ° up and down slope transportation, widely used in IT, medicine, clothing, hardware, department stores, tires, food, e-commerce and other distribution centers.

Problems solved by technology

[0003] Existing long belt conveyors are prone to conveyor belt deviation. In actual use, the material is more prominent in the oblique upward movement in the middle of the conveyor belt, and the position and direction of the material loading at the reloading point have deviations from the conveyor belt. It has a very large impact. The larger the angle between the loading direction of the material and the transfer surface, the greater the side impact on the conveyor belt, especially for heavy boxes above 15KG, several places on the same conveyor belt machine are oblique or parallel at the same time. When loading goods horizontally, it is difficult to avoid the deviation of the conveyor belt, which will cause the side of the conveyor belt to rub against the frame or other parts, increase the load, and reduce the service life. More importantly, the material cannot run in the middle of the conveyor belt as designed , which directly affects the conveying and sorting effect

[0004] At present, the deviation correcting devices of the belt conveyor are designed at both ends of the conveyor belt, or in the middle of the return section, which cannot effectively prevent and correct the deviation of the conveyor belt in the middle of the long belt conveyor’s bearing surface, and the conveyor belt below the bearing surface Only rollers or pallets are installed, which do not have any restraint on the lateral drift of the conveyor belt
