Two opposing guide rails 15 are also provided on the outer side of the frame 1, and sliders 16 are slidably installed inside each guide rail 15. The two sliders 16 are fixedly installed on both sides of the platform 2. The sliders 16 on both sides of the platform 2 slide along the guide rails 15 on the outer side of the frame 1 to ensure that the lifting process is vertical and without deviation. A conveying roller assembly for material conveying is provided on the top of the platform 2, and a baffle plate 3 is also provided on the top of the platform 2. The drive motor 9 and the connecting block 10 drive the baffle plate 3 to rotate. The drive motor 9 is fixedly installed on one side of the bracket 4, and the output end of the drive motor 9 is fixedly connected to one end of the connecting block 10. One side of the connecting block 10 is fixedly connected to one end of the baffle plate 3. By starting the drive motor 9, the connecting block 10 is driven to rotate. The connecting block 10 is fixedly connected to the baffle plate 3. The drive motor 9 can rotate the baffle plate 3 to a vertical or horizontal position by rotating it forward or backward. In the vertical position, it can prevent the material from sliding down. It is suitable for fixing the material when the platform 2 is raised and lowered. In the horizontal position, it can release the material and allow it to slide out along the roller shaft 8 to the designated position.

[0023] In one specific implementation, the conveyor roller assembly includes a support 4, a power motor 5, a gear 6, a gear 7, and multiple roller shafts 8. The support 4 is fixedly installed on the top of the platform 2, the power motor 5 is fixedly installed on the platform 2, the output end of the power motor 5 is fixedly connected to the gear 6, the gear 7 is fixedly connected to one end of one of the roller shafts 8, and the gear 7 meshes with the gear 6. The two ends of the multiple roller shafts 8 are respectively rotatably installed on both sides of the support 4, and the ends of the roller shafts 8 are connected to each other through multiple chain mechanisms. The output end of the power motor 5 fixed on the platform 2 drives the gear 6 to rotate, and the gear 6 meshes with the gear 7 fixed to the end of one of the roller shafts 8, driving the roller shaft 8 to rotate. The other roller shafts 8 are connected through chain mechanisms and rotate synchronously.

[0024] It should be noted that the chain mechanism, such as the timing belt or metal chain, is connected to the end of each roller 8 to ensure that all rollers 8 rotate at the same speed and to avoid material jamming.

[0025] In one specific implementation, the lifting assembly includes a horizontal shaft 11, two opposing mounting seats 12, a second power motor 17, a transmission chain 18, and two opposing transmission sprockets 19.

The other transmission sprocket 19 is fixedly mounted on the outer surface of the horizontal shaft 11. The two transmission sprockets 19 are connected by a transmission chain 18. After the power motor 17 fixed on the top of the frame 1 is powered on, its output end drives one of the transmission sprockets 19 to rotate. The two transmission sprockets 19 are connected by the transmission chain 18. The power is transmitted to the sprocket on the outer surface of the horizontal shaft 11, driving the horizontal shaft 11 to rotate.

[0026] The working principle of this utility model is as follows: When the device is in use, the material is placed in the conveyor roller group and blocked by the baffle plate 3. After the power motor 17 is powered on, its output end drives one of the conveyor sprockets 19 to rotate. The two conveyor sprockets 19 are connected by the conveyor chain 18. The power is transmitted to the sprocket on the outer surface of the horizontal shaft 11, driving the horizontal shaft 11 to rotate. When the horizontal shaft 11 rotates, the feeding tray 13 fixed on it rotates synchronously. The feeding tray 13 releases the rope 14, and the platform 2 is unfolded by the lowering rope 14. The feeding tray 13 winds the rope 14, and the platform 2 is retracted by the lifting rope 14. One end of the rope 14 is fixed to the top of the platform 2, and the other end is wound around the feeding tray 13. The lifting and lowering of the platform 2 is achieved by controlling the rotation direction of the feeding tray 13. The drive motor 9 is started to drive the connecting block 10 to rotate. The connecting block 10 is fixedly connected to the baffle plate 3. The drive motor 9 can rotate the baffle plate 3 to a vertical or horizontal position by rotating it forward or backward. In the vertical position, it prevents the material from sliding down. It is suitable for fixing the material when the platform 2 is lifted and lowered. In the horizontal position, it releases the material and allows it to slide out along the roller shaft 8 to a designated position. The output end of the power motor 5 drives the gear 6 to rotate. The gear 6 meshes with the gear 7 fixed at the end of one of the roller shafts 8, driving the roller shaft 8 to rotate. The other roller shafts 8 are connected by a chain mechanism and rotate synchronously to transport the material.
