[0031] Specifically, the starting motor 4 drives the gear 6 to rotate. Because the two gears 6 are meshed, the gear 6 drives the other gear 6 to rotate, and the gear 6 drives the eccentric shaft 7 to rotate together. The eccentric shaft 7 drives the connecting rod 8 and drives the push rod 11 through the support rod 9. The push rod 11 slides inside the bracket 10, and the push rod 11 drives the push plate 12 to slide on the top of the conveyor belt 2 and gathers the materials in the center of the conveyor belt 2, so as to avoid collisions between the materials, causing the materials to fall and be damaged, and affecting their quality. The workbench 1 plays the role of installing the remaining parts, the conveyor belt 2 plays the role of transporting materials to the CNC machine tool, and the bracket 10 plays the role of limiting the push rod 11.

[0032] Reference Figure 1 and Figure 3 The lifting assembly includes a base 14, and both sides of the top of the base 14 are provided with sliding grooves 15. A slider 16 is slidably connected to one side of the sliding groove 15, and a fixed block 17 is fixedly connected to the other side of the sliding groove 15. A bracket group 18 is arranged on the top of the lower sliding groove 15 and the lower fixed block 17. A cylinder 19 is fixedly connected to the top of the base 14, and a sliding rod 20 is fixedly connected to the output end of the cylinder 19, and both ends of the sliding rod 20 are fixedly connected between the two lower sliders 16.

[0033] Specifically, the slide bar 20 is driven to slide on the top of the base 14 by starting the cylinder 19. When the slide bar 20 slides on the top of the base 14, it will drive the lower slide bar 16 to slide inside the lower groove 15, and then drive the upper slide bar 16 to slide inside the upper groove 13 through the rotating shaft in the middle of the bracket group 18. At the same time, the fixed blocks 17 inside the upper groove 13 and the lower groove 15 have the effect of fixing and stabilizing the bracket group 18. Finally, the workbench 1 is pushed through the bracket group 18, so as to raise the workbench 1 to a suitable position.

[0034] Reference Figure 1 - Figure 3The connecting assembly includes an eccentric shaft 7, the bottom of the eccentric shaft 7 is fixedly connected to the top edge of the gear 6, a connecting rod 8 is fixedly connected to the outside of the eccentric shaft 7, one end of the connecting rod 8 is rotatably connected to the support rod 9, the push plate 12 is slidably connected to the top of the conveyor belt 2, the bottom of the upper slider 16 is slidably connected to one side of the upper slide groove 13, the upper fixed block 17 is fixedly connected to the other side of the upper slide groove 13, the lower slider 16 and the fixed block 17 are externally rotatably connected to the bottom of the bracket group 18, the upper slider 16 and the fixed block 17 are externally rotatably connected to the top of the bracket group 18, a rotating shaft is provided in the middle of the bracket group 18, the bottom of the slide rod 20 is slidably connected to the top of the base 14, and the side of the support rod 9 away from the connecting rod 8 is rotatably connected to the end of the push rod 11 away from the push plate 12.

[0035] Specifically, the eccentric shaft 7 drives the connecting rod 8, the connecting rod 8 drives the support rod 9 to move together, the support rod 9 drives the push rod 11, the push rod 11 slides inside the bracket 10 to drive the movement of the push plate 12, and the push plate 12 gathers the materials on the top of the conveyor belt 2, so as to avoid collision between the materials and cause the materials to fall and be damaged.

[0036] The upper slide groove 13 serves to facilitate the upper slider 16 to slide inside it, the slider 16 serves to slide inside the upper slide groove 13 and the lower slide groove 15, and the lower slider 16 drives the upper slider 16 to slide through the bracket group 18. The fixed block 17 serves to support and stabilize the bracket group 18 when the slider 16 slides. The bracket group 18 cooperates with the slider 16 and the fixed block 17, thereby allowing the workbench 1 to be raised and lowered through the bracket group 18. The lower slide groove 15 serves to facilitate the slider 16 to slide and drive the bracket group 18, and the fixed block 17 is fixed inside the lower slide groove 15 to provide fixed support for the bracket group 18.

[0037] Working principle: When the CNC machine tool is feeding, the workbench 1 is first adjusted to a reasonable position according to the feeding position, and the cylinder 19 is first started to drive the slide bar 20 to slide on the top of the base 14. When the slide bar 20 slides, it drives the bottom slide block 16 to slide inside the lower slide groove 15, and then drives the upper slide block 16 to slide inside the upper slide groove 13 through the rotating shaft in the middle of the bracket group 18, and then pushes the workbench 1 through the bracket group 18, so as to raise the workbench 1 to a suitable position, and then starts the motor 4 to drive the gear 6 to rotate. Because the two gears 6 are meshed, the gear 6 drives another gear 6 to rotate, and the gear 6 drives the eccentric shaft 7 to rotate together. The eccentric shaft 7 drives the connecting rod 8 and drives the push rod 11 together through the support rod 9. The push rod 11 slides inside the bracket 10, and the push rod 11 drives the push plate 12 to slide on the top of the conveyor belt 2, thereby gathering the materials in the center of the conveyor belt 2.
