Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, and more specifically to an automatic paper aligning adjustment structure of a die-cutting machine. Background Art

[0002] Die-cutting machine is also called die-cutting machine, cutting machine, CNC punching machine, mainly used for die-cutting, creasing and hot stamping operations, laminating, automatic waste discharge of some corresponding non-metallic materials, self-adhesive, EVA, double-sided tape, electronics, mobile phone pads, etc. Die-cutting machine uses steel knife, hardware mold, steel wire, and applies a certain pressure through the stamping plate to roll and cut the printed product or cardboard into a certain shape. It is an important equipment for post-printing packaging processing. After using the die-cutting machine to process the paper, it is necessary to align and organize the paper for subsequent operations.

[0003] After searching, the utility model patent with the announcement number CN210162882U discloses an automatic paper alignment adjustment structure of a die-cutting machine, including a paper collection wall panel and an automatic paper alignment adjustment unit, each of which includes a paper alignment cylinder, a slide rail, a slide seat, a motor and a gear matching part. A fixed seat is fixed on the paper collection wall panel, the slide seat is installed below the fixed seat, the slide rail is installed in the slide seat, the gear matching part includes a rack and a gear, a gear is installed at the shaft end of the motor, the gear is meshed with the upper rack, the rack is installed below the slide rail, and the paper alignment cylinder is installed on the slide rail. At the end of the paper aligning cylinder, an aligning paper board is installed, and a paper collecting wooden board is arranged between the automatic paper aligning adjustment parts on the left and right sides, and the paper collecting wooden board is located below the aligning paper board; when the die-cutting machine collects paper, the paper needs to be aligned left and right. In order to adapt to the size of the paper, the paper aligning cylinders on the left and right sides of the paper collecting wall board move to drive the position adjustment of the aligning paper board. The movement of the paper aligning cylinder is coordinated through the gear rack. When the gear rotates, the slide rail on the rack also moves accordingly. The movement of the slide rail causes the paper aligning cylinder to move, and finally the left and right aligning paper boards are pushed and adjusted to the appropriate position to adapt to the size of the paper.

[0004] However, the above patent still has the following shortcomings: when the paper receiving platform and the paper receiving wooden board are adjusted up and down by the sprocket and the chain, the paper receiving platform and the paper receiving wooden board are prone to shake, affecting the collection of paper; in addition, only the paper aligning boards on both sides can align only the two sides of the paper, and the paper aligning effect is poor. For this reason, we propose an automatic paper aligning adjustment structure for a die-cutting machine. Utility Model Content
