Telescopic belt conveyor

Abstract

According to the telescopic belt conveyor, the sliding groove is formed in the inner wall of the fixed supporting frame, the sliding block is arranged on the outer side of the telescopic supporting frame, and the sliding block is in sliding connection with the sliding groove in a matched mode, when the telescopic conveying assembly needs to be stretched, the first driven wheel is detached from the fixed supporting frame, then the telescopic supporting frame is dragged to stretch, and the telescopic conveying assembly is fixed. When the conveying belt is stretched to the needed length, the conveying belt is tightened, then the first driven wheel is installed on the fixed supporting frame, the first driven wheel is far away from the driving wheel at the moment, then the motor is started to rotate forwards, so that objects to be conveyed can move from the bottom of the fixed supporting frame to the top of the telescopic supporting frame, and the transition slope plays a transition role; the risk that the articles to be conveyed fall due to the height difference of the two conveying surfaces is avoided; the length ratio of the fixed supporting frame to the telescopic supporting frame is 2: 1, so that the conveying distance can be prolonged, and the multi-length conveying requirement is met; on the contrary, when the motor is started to turn over, the objects to be conveyed can move from the top of the telescopic supporting frame to the bottom of the fixed supporting frame, and reverse conveying is achieved.

When it is necessary to extend the telescopic conveying assembly 2, the first driven wheel 14 is removed from the fixed support frame 11, and then the telescopic support frame 21 is dragged to extend. When it is extended to the required length, the conveyor belt 15 is tightened, and then the first driven wheel 14 is installed on the fixed support frame 11. At this time, the first driven wheel 14 is away from the driving wheel 13 (compared to the attached Figure 3 The distance between the two is shown), the conveyor belt 15 is tightened again by using the first driven wheel 14 and the second driven wheel 22, and then when the starting motor 12 rotates forward, the items to be transported can be moved from the bottom of the fixed support frame 11 to the top of the telescopic support frame 21, wherein the transition slope 16 plays a transition role to avoid the risk of the items to be transported falling due to the height difference between the two transport surfaces; the length ratio of the fixed support frame 11 to the telescopic support frame 21 is 2:1, which can extend the conveying distance and meet the needs of multi-length conveying; on the contrary, when the starting motor 12 is flipped, the items to be transported can be moved from the top of the telescopic support frame 21 to the bottom of the fixed support frame 11 to achieve reverse conveying.
