When the telescopic conveying mechanism operates, the fixed roller 1 is fixed, and the movable roller 2 can move along the front-back direction, so that the telescopic conveying mechanism can be switched between an extending state and a retracting state, and the joint gap between the telescopic conveying mechanism and an upstream mechanism and a downstream mechanism can be conveniently adjusted.
As one of the installation modes of the movable roller 2, the telescopic transmission mechanism further comprises a movable roller installation frame 6, the movable roller 2 is installed on the movable roller installation frame 6, and the movable end of the telescopic driving mechanism 4 is connected with the movable roller installation frame 6.
In order to enhance the stability of the traveling roller 2 during traveling, the traveling roller mount 6 is mounted on the frame 5 by a slide mechanism 7.
The telescopic driving mechanism 4 can be various conventional telescopic mechanisms such as an air cylinder, a hydraulic cylinder, an electric cylinder, a motor belt transmission mechanism, a motor chain transmission mechanism, a nut screw rod transmission mechanism, a gear rack transmission mechanism or a linear motor, and the telescopic driving mechanism 4 is an air cylinder in the embodiment.
The telescopic conveying mechanism causes the conveying belt 3 to be stretched and slackened when switched between the extended state and the retracted state, and if the retracted distance is excessively long, the slackened state may cause the conveying belt 3 to be displaced or fall off from the fixed roller 1 and the moving roller 2. The problem can be solved with the following two solutions:
the first scheme is as follows: the transmission band can adopt the elasticity transmission band, and the elasticity transmission band is elongated when telescopic conveying mechanism stretches out the state, and the elasticity transmission band resumes former length when telescopic conveying mechanism retracts the state.
The second scheme is as follows: as shown in the figure of the present embodiment, the telescopic conveying mechanism further includes a secondary fixed roller 17 and a secondary movable roller 18, the secondary fixed roller 17 and the secondary movable roller 18 are arranged in parallel with the fixed roller 1 and the movable roller 2, the secondary fixed roller 17 is installed on the frame 5, the telescopic driving mechanism 4 is used for driving the movable roller 2 and the secondary movable roller 18 to synchronously move in the front-back direction, the fixed roller 1 is located in front of the movable roller 2, the secondary fixed roller 17 is located behind the secondary movable roller 18, and the conveying belt 3 bypasses the fixed roller 1 and the movable roller 2 and then bypasses the secondary movable roller 18 and the secondary fixed roller 17.
