Description

Technical Field

[0001] The utility model relates to a card mounting machine, in particular to a glue coating roller position regulating device of the card mounting machine. Background Art

[0002] The card mounting machine is a special equipment that can achieve paper mounting. Before the paper is mounted, it is necessary to glue the paper. The gluing mechanism mainly includes a glue box, a gluing roller and a drum. When working, the gluing roller dips the glue in the glue box and cooperates with the drum to achieve the gluing of the paper. The traditional gluing roller is rotatably set on the frame, so its position is fixed, which leads to a fixed gap between the gluing roller and the drum, that is, the amount of gluing of the paper is constant. In actual use, the amount of glue required for paper of different materials or thicknesses may vary to a certain extent. After using the above mechanism for gluing, it will affect the subsequent bonding operation. Utility Model Content

The first and second swing frames are connected by a connecting rod 24. The first swing frame 15 is provided with an arc-shaped tooth 16, which meshes with the adjustment gear 17. Specifically, the first swing frame 15 is provided with a clearance groove 18, and the arc-shaped tooth 16 is provided on the inner wall of the clearance groove 18, and the adjustment gear 17 extends into the clearance groove 18. The adjustment gear 17 is connected to the rotation adjustment component. In this embodiment, the rotation adjustment component includes a first motor 5, and the output end of the first motor 5 is connected to the gear box 12. The output shaft of the gear box 12 is connected to the adjustment gear 17, and the output shaft is also connected to the rotating seat 6. The rotating seat 6 is connected with a sensing cam 9, and a first limit sensor 10 and a second limit sensor 11 are provided corresponding to the sensing cam 9. The first and second sensors can control the action of the first motor 5. The sensing cam 9 is provided with an arc groove 8, and the screw portion of the screw 7 passes through the arc groove 8 and is screwed to the rotating seat 6 to achieve locking of the sensing cam 9 and the rotating seat 6.
