the adsorption component comprises an adsorption hole arranged on the surface of the material clamping roller, an air source through hole arranged on the roller shaft and negative pressure suction equipment;

the air source through hole is connected with the negative pressure suction equipment, and a negative pressure cavity is formed between the air source through hole and the material clamping roller.

Particularly, the utility model provides a negative pressure suction equipment, its trachea are fixed in on the crossbeam of pressing from both sides the material roller, and press from both sides the material roller and be fixed in the crossbeam through the bearing, so press from both sides the rotation of material roller and can not drive crossbeam pivoted, so can not take place trachea winding phenomenon.

The utility model discloses an automatic paper receiving mechanism utilizes negative pressure suction to firmly adsorb the adhesive layer in pressing from both sides material roller surface, and material is rolled up when conveying to pressing from both sides material conveyer department via transfer apparatus after the section, and two clamp material roller centre grippings of material book incision, incision positive and negative both sides are all pasted by the adhesive layer, have increased the thickness and the intensity of incision department, have avoided the cross cutting to arrange the paper fault absolutely when useless.

Furthermore, the adsorption holes are uniformly arrayed along the axial direction of the material clamping roller.

Furthermore, the adsorption holes are uniformly arrayed along the circumferential direction of the material clamping roller.

Specifically, the adsorption holes are double exhaust holes. The arrangement of the double exhaust holes can be beneficial to adsorbing the upper end and the lower end of the adhesive layer so as to prevent tilting.

The adsorption holes of the uniform array can ensure the plane adsorption of the adhesive layer, and the phenomenon that the adhesive layer is wrinkled or warped on the surface of the roller due to uneven adsorption to influence the smooth adhesion at the material roll cutting opening is avoided.

The utility model also provides a roll change equipment does not shut down, it includes material and rolls up conveyer and aforementioned automatic paper receiving mechanism, material is rolled up material after the material conveyer with the incision and is rolled up material conveying to automatic paper receiving mechanism department, and it is attached by the adhesive layer at the paper receiving station to roll up the material interface.

Compared with the prior art, the utility model provides an automatic paper receiving mechanism and do not shut down the equipment of changing a roll have following advantage:

when the material roll is conveyed to the paper receiving station, the automatic paper receiving mechanism automatically attaches the adhesive layers to the two side surfaces of the cut of the material roll so as to improve the strength and toughness of the cut and avoid the paper breaking fault of the cut during the overmould cutting;

the adhesive adsorption device of the automatic paper receiving mechanism adsorbs the adhesive-free surface of the adhesive layer to the material clamping roller by utilizing negative pressure, the structure is simple, the operation and the maintenance are convenient, and the automatic roll change can be realized without stopping the machine;

the non-stop roll changing equipment with the automatic paper receiving mechanism can realize non-stop automatic roll changing of the web-shaped material, and the automatic roll changing and winding and unwinding processes of the material roll can protect the automatic gluing of the material roll notch so as to smoothly realize the cross die cutting of the material roll notch and greatly reduce the paper breaking waste paper rate.
