[0039] Example 3

[0040] See also Figures 1 to 8 A telescopic structure for a single-sheet lifting cage in woodworking machinery is disclosed. The movable idler roller 15 is mounted on an idler roller slide 16 via a bearing structure. The idler roller slide 16 is slidably mounted on an idler roller rail 17, which is located on a base frame 1. The idler roller slide 16 is connected to the telescopic end of a reverse cylinder 26. One end of the drive idler roller 10 is equipped with a drive sprocket 13, which is connected to an idler roller drive motor 18 via a drive chain 12. The idler roller drive motor 18 is located on the base frame 1.

[0041] The structure and connection relationships of the remaining parts are the same as those described in the foregoing embodiments.

[0042] In the technical solution described in this embodiment, in order to ensure the stability of the movement of the movable roller 15, the movable roller 15 is set on the roller slide 16, and the roller slide 16 is slidably set on the roller slide rail 17. The roller slide rail 17 is arranged parallel to the telescopic frame 19 and is fixedly connected to the bottom frame 1.

[0043] In the technical solution described in this embodiment, the idler slide 16 is connected to the reverse cylinder 26, which is located on the bottom frame 1 and arranged along the length direction of the idler slide rail 17, thereby realizing the adjustment of the conveying length of the conveyor belt 11. The reverse cylinder 26 is a hydraulic cylinder or a pneumatic cylinder.

[0044] In this application, individual boards and pads can be conveyed to the conveyor belt 11 in the single lifting cage by the front-end transmission platform. The bottom frame 1 can realize the loading layer at the rear end under the action of the lifting chain, and the position height is the same as that of the single board to be loaded.

Specifically, firstly, the telescopic end of the reverse cylinder 26 drives the moving idler 15 and the idler slide 16 to move along the idler slide rail 17 in the opposite direction to the telescopic idler 21, so that the conveyor belt 11 has a forward extension margin; secondly, in the process of the telescopic rod 22 driving the telescopic idler 21 to extend out of the telescopic frame 19, it needs to rely on the telescopic end of the forward cylinder 25 to move. Since the telescopic end of the forward cylinder 25 is connected to the bottom frame 1, the bottom end of the forward cylinder 25 drives the forward push plate 27 and the rod connecting rod 28 to move. The rod connecting rod 28 is connected to the telescopic rod 22, which in turn drives the telescopic rod 22 and the telescopic idler 21 to move. After the above actions are completed, the conveyor belt 11 can extend towards the feeding position. After extension, the idler drive motor 18 can drive the drive chain 12 and drive sprocket 13 to rotate. The drive sprocket 13 drives the drive idler 10 to rotate. The drive idler 10, guide idler 14, moving idler 15, and telescopic idler 21 enable the conveyor belt 11 to complete the conveying of the plate. After the plate is conveyed, the plate push rod 6 is aligned with the plate by the push cylinder 7.
