Description

Technical Field

[0001] This application relates to the field of conveyor belts, and more particularly to conveyor belt drive tensioning devices. Background Technology

[0002] Conveyor belts, also known as transport belts, are rubber and fiber / metal composite products, or plastic and fabric composite products, used in belt conveyors to carry and transport materials. Conveyor belts are widely used in industries such as cement, coking, metallurgy, chemicals, and steel for short-distance and small-capacity conveying applications.

[0003] Conveyor belts need to be tightened during use, but in actual use, the toughness of the conveyor belt makes it easy to loosen, so it needs to be tightened to prevent slippage. However, in actual use, the conveyor rollers of existing conveyor belts are fixed, making it inconvenient to adjust them. Utility Model Content

[0004] To address the problem of inconvenient tension adjustment in existing conveyor belts, this application provides a conveyor belt drive tensioning device.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application provides an adjustment component on the conveyor seat.

[0022] 2. In this application, the servo motor drives the worm gear in the adjustment assembly to rotate the worm wheel, which facilitates the rotation of the bidirectional screw. When the bidirectional screw rotates, it works with the threaded sleeve and connecting plate to adjust the position of the drive column. Then, the position of the second conveyor roller is adjusted by moving the sliding frame, thereby adjusting the tension of the conveyor belt. Attached Figure Description

Symmetrically arranged threaded sleeves 15, with one end of each of the two connecting plates 13 rotatably connected to the two threaded sleeves 15 respectively. When the bidirectional screw 14 rotates, it drives the two threaded sleeves 15 to move towards or away from each other. When the two threaded sleeves 15 move towards each other, they directly cooperate with the connecting plates 13 to drive the drive column 12 to extend. Conversely, when the two threaded sleeves 15 move away from each other, they directly cooperate with the connecting plates 13 to pull the drive column 12 back into the adjusting seat 10.
