Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a small-sized retractable belt conveying device. Background Art

[0002] Belt conveyor is also called belt conveyor, and belt conveyor is the abbreviation of belt conveyor. It has fixed and mobile types, simple structure and high efficiency. It is a continuous conveying machine with flexible conveyor belt as material carrying and traction component. An endless conveyor belt surrounds the driving roller and the redirecting roller. The upper and lower branches between the two rollers are supported by several rollers. The material is placed on the upper branch, and the friction between the driving roller and the belt is used to drag the conveyor belt and the material to run. It is suitable for conveying bulk materials and finished items in horizontal and inclined directions, and can also be used in assembly lines for certain process operations.

[0024] The driving member 3 comprises a servo motor 3.1 fixed to the top surface of the support plate 1.8 and a gear 3.2 fixedly mounted on the power output shaft of the servo motor 3.1 and meshing with the rack 1.6.2.

[0025] The conveyor belt assembly 2 includes a row of upper rollers 2.1, a row of lower rollers 2.2 arranged parallel to the lower side of the upper rollers 2.1, a plurality of connecting beams 2.3, a guide roller 2.4 arranged just below the upper roller 2.1 at one end, a guide roller 2.5 arranged just above the inner side of the guide roller 2.4, a storage roller 2.7 arranged inside the guide roller 2.4, and an adhesive belt 2.6 which passes through the upper roller 2.1, the guide roller 2.4, the storage roller 2.7, the guide roller 2.5 and the lower roller 2.2 in sequence. The two ends of the connecting beam 2.3 are respectively rotatably mounted on the central axis ends of the lower roller 2.2 and the upper roller 2.1 adjacent thereto, and the central axis of the upper roller 2.1 at one end is connected to the upper roller 2.1. The front and rear ends are rotatably mounted on the front and rear walls of the groove-shaped member 1.1, and the front and rear ends of the central axis of the upper roller 2.1 at the other end are rotatably mounted in the support hole 1.6.1 on the support beam 1.6. One end of the rear wall of the groove-shaped member 1.1 corresponding to the guide roller 2.4 is provided with a conveying motor 1.3 for driving the upper roller 2.1 at the corresponding end to rotate.
