Description

TECHNICAL FIELD

[0001] The utility model relates to sanitary product core body processing equipment technical field, concretely relates to a sanitary product core body slitting and coating integrated equipment. BACKGROUND

[0002] The absorbent core is an important structure inside paper diapers, pull-ups, sanitary napkins and other sanitary products, which usually needs to be processed through multiple processes, including compounding absorbent material and non-woven fabric into an absorbent body, slitting the absorbent body into a long strip of a set width, wrapping a layer of non-woven fabric on the surface of the long strip of absorbent body to obtain an absorbent core, and then cutting the absorbent core to a set length to be compounded into paper sanitary products. During the processing of the absorbent core, the width of the slitting of the absorbent body needs to be determined according to the absorption performance and type of the sanitary product, and the number of slitting will also change with the change of the width, so the slitted absorbent body is usually wound or stacked for storage, and then transferred to the coating equipment for coating non-woven fabric on the surface of the absorbent body. The process of storage and transfer between slitting and coating increases the processing efficiency of the absorbent core.

[0003] Based on the above situation, the Chinese patent with publication number CN208259850U discloses a paper diaper core slitting device with adjustable spacing, which includes a mounting frame, a servo motor, a shaft, a cutter, a mounting rail, a clamping wrench, a cylinder and a blade. The servo motor is fixedly installed on the mounting frame and connected with the shaft. Two mounting rails are fixedly installed on the mounting frame in a V-shaped structure. The cutter is fixedly installed on the mounting rail through the clamping wrench. The Chinese patent with publication number CN213098802U discloses a coating forming device for core production, which includes a protective shell, a processing box fixedly installed on one side of one end of the protective shell, a processing roller movably connected to the inside of the processing box, and a transmission belt movably connected to one end of the protective shell.

[0004] At present, the sanitary product core is usually slitted and coated by the slitting device and the coating forming device disclosed above. Since the slitting device can slitting into multiple long strips of absorbent body, if the slitting and coating of the core are to be performed on the same production line, multiple coating forming devices need to be arranged, which makes it difficult to arrange the equipment and increases the occupied area of the production line. Therefore, the slitted absorbent body is transferred to another production line for non-woven fabric coating operation after being wound or stacked, which easily affects the efficiency of core production, and the absorbent material at the edge position of the absorbent body is easy to fall off during winding or stacking and transfer, affecting the absorption performance of the core. Therefore, there is still room for improvement in the above-mentioned core processing equipment. UTILITY MODEL CONTENTS
