Control system and control method for die wheel

Abstract

The invention discloses a control system and control method for a die wheel. Two sides of the die wheel are each provided with a plurality of die shoes; a forming cavity for a cotton core is formed between the die shoes at the two sides; the control system comprises a width detecting device, a depth detecting device, a width adjusting device and a depth adjusting device, wherein the width detecting device detects the forming width of the cotton core; the depth detecting device detects the forming depth of the cotton core in the forming cavity; the width adjusting device correspondingly adjuststhe die shoes according to the detection signal of the width detecting device so as to adjust the width of the forming cavity; and the depth adjusting device correspondingly adjusts the die shoes according to the detection signal of the depth detecting device so as to adjust the depth of the forming cavity to further adjust the forming thickness of the cotton core. According to the control system, the width of the forming cavity is automatically adjusted by detecting the forming width of the cotton core so as to adapt to forming of cotton cores different in width, so that the die wheel is prevented from being disassembled; the depth of the forming cavity is adjusted by adjusting the die shoes so as to adapt to forming of the cotton cores different in thickness, and the depth of the forming cavity is automatically adjusted by detecting the forming thickness of the cotton core, so that not only is the die wheel prevented from being disassembled, but also overflowing of filler of the cotton core is avoided.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a mold wheel control system and a control method thereof. Background technique [0002] Disposable absorbent articles such as baby diapers, adult incontinence products, and sanitary napkins are well known. Such absorbent articles mainly include a liquid-permeable surface layer, an absorbent body, and a liquid-impermeable bottom layer that are stacked sequentially from top to bottom. , the absorbent body is used to absorb and retain human excretion fluid, such as urine, menstrual blood, and the liquid-permeable surface layer is used to provide a comfortable and dry feeling when in contact with the body, while allowing liquid to pass freely and enter the lower absorbent body without The liquid-permeable backsheet serves to retain absorbed liquid within the absorbent body, thereby preventing the absorbed liquid from soiling the wearer's pants. [0003] Traditional absor...

AI Technical Summary

Problems solved by technology

[0003] Traditional absorbent cores are generally molded on a mold wheel, and there are usually mold tiles inside the mold wheel, and the mold tiles are fixed on the mold wheel. When adjustment is required, the mold wheel needs to be disassembled for manual adjustment. The production efficiency Low, and the weight of the mold wheel is heavy, requiring at least 4 operators to disassemble, which increases labor costs and is easy to cause work-related injuries
