The negative pressure head 51 of the variable speed transfer mechanism 5 adsorbs the hollowed-out core body and then transfers at an accelerated speed until the transfer linear speed of the hollowed-out core body is the same as the linear speed of the surface layer material conveyed by the product conveying unit 7, so that the hollowed-out core body is transferred to the surface layer material conveyed by the product conveying unit 7 through the glue spraying port 6, the hollowed-out core body is positioned and adhered to the surface layer material conveyed by the product conveying unit 7, and the positioning is accurate and does not run out.
Referring to fig. 2 and 3, the speed-changing transfer mechanism 5 in this embodiment includes four speed-changing transfer disks, negative pressure adsorption cassettes a, b, c, and d disposed on the speed-changing transfer disks, and a speed-changing mechanism for driving the speed-changing transfer disks to rotate at variable speeds.
