Three-roll welding equipment and welding method for adult incontinence pants and baby pull-up pants production line

Abstract

The invention relates to three-roller welding equipment in the production line of adult diapers and baby training pants and a welding method. According to the invention, two ends of a lower roller are in running fit with the lower end of a griff plate; six lower heating module strips are equidistantly mounted on the surface of the lower roller; three upper rollers are equidistantly mounted above the surface of the lower roller, and the two ends of the three upper rollers are respectively in running fit with the upper part of the griff plate through bearing supports; the three upper rollers are respectively driven by an upper servo-driven synchronization control mechanism to rotate in the same direction via a shaft coupling; upper heating module strips are symmetrically mounted on the surfaces of the upper rollers; conducting wire grooves are respectively formed on central spindles of the upper and the lower rollers, output ends of power cords in the conducting wire grooves power the electric heating tubes in the upper heating module strips, and the input ends are connected with a power source output end of a rotary electricity collecting ring fixed on the griff plate; the power source input end of the rotary electricity collecting ring is connected with a power source; and hydraulic cylinders are mounted on the griff plate, and the piston end faces of the hydraulic cylinders are connected with the bearing supports at the two ends of the upper rollers through connection blocks.

Description

technical field [0001] The invention relates to a multi-layer sheet-shaped material used for multiple effective welding of the same part in adult incontinence pants and baby pull-up pants, and on the premise that the surface layer of the welded part will not be overheated, hardened and other adverse effects, ensuring multiple The invention relates to a three-roll welding equipment and welding method for a production line of adult incontinence pants and baby pull-up pants fully bonded with thin sheet materials, and belongs to the field of non-woven fabric welding equipment manufacturing. Background technique [0002] CN101508186A, titled "full automatic control non-woven hot-press welding equipment and welding method", including a PLC controller, a groove structure on the upper part of the frame, and holes in the lower part, and the lower electric heating welding wheel axle passes through the lower slider and is located at the lower part of the frame In the hole and the lower...

AI Technical Summary

Problems solved by technology

However, since baby pull-up pants and adult incontinence pants are made of multi-layer materials before welding, local welding is not firm and the seal is not good. If artificially to improve the welding quality, it is necessary to increase the contact time of the upper and lower embossing, which will affect the host. Production speed, if the pressing temperature is set too high, the surface material will be partially overheated, and it will be burned through or hardened, which will affect the use function and appearance quality
