[0031] Example 2

[0032] See also Figures 1 to 5 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.

[0036] Example 3

[0037] See also Figures 1 to 5A telescopic lifting cage structure for woodworking machinery is disclosed, wherein the base frame 1 has an upwardly extending lifting frame 2 at its corners. The lifting frame 2 has lifting chain seats 4 respectively installed on its outer side via a base body. The lifting chain seats 4 are located at the top and bottom ends of the lifting frame 2 base body. Lifting guide wheels 3 are also installed on the outer side of the lifting frame 2 base body.

[0039] In the technical solution described in this embodiment, the lifting chain seat 4 can be connected with the lifting chain, thereby enabling the bottom frame 1 to follow the movement of a single lifting cage. The lifting guide wheel 3 can be slidably connected with the guide rail on the outer frame to ensure the stability of the bottom frame 1 during the lifting process.

[0040] 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. The conveyor belt 11 can adjust the extension length of the conveyor belt 11 relative to the bottom frame 1 with the cooperation of the telescopic idler 21, the moving idler 15, the guide idler 14, the drive idler 10, the forward cylinder 25, the reverse cylinder 26, the forward push plate 27 and the rod connecting rod 28, so as to stably realize the smooth transmission between equipment and the stable conveying of the board and pad to the loading position.

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.
