The technical effect of positioning and fixing the core body of a diaper.

Further, a slideway is provided on the top of the workbench, the positioning block is slidably connected to the slideway, an end of the slideway away from the conveyor belt is provided with a through hole, and one end of the positioning block away from the conveyor belt is rotatably connected There is a screw, and the outer wall of the screw is screwed on the through hole.

Beneficial effects: The technical solution realizes the adjustment of the position of the positioning block relative to the sliding seat by rotating the screw.

Further, a handle is welded and fixed at one end of the screw rod away from the positioning block.

Beneficial effects: The technical solution adds a handle to facilitate the operator to rotate the screw.

Further, the worktable is also fixedly connected with a hole-cutting mechanism for cutting holes for the core body of the diaper on the conveyor belt.

Beneficial effects: In this technical solution, a hole-cutting mechanism is added on the worktable to realize the opening of the surface of the core body of the diaper during the conveying process, which greatly improves the processing efficiency of the core structure of the diaper.

Further, the hole cutting mechanism includes a cutting roller, a driving motor is fixedly connected to the cutting roller coaxially, and a plurality of blades for opening holes are fixedly connected to the outer wall of the cutting roller.

Beneficial effect: The technical solution adopts the cutting roller to realize the opening of the core structure of the diaper. As the driving motor drives the cutting roller to rotate, each diaper core will be cut by the blade on the surface of the cutting roller when passing through the cutting roller. cut.

Further, the side of the chute close to the outside communicates with the outside.

Beneficial effects: The technical solution makes the outer wall of the chute communicate with the outside, so that the operator can disassemble or replace the slide plate in the chute, and it is convenient for the operator to install the slide plate.
