Equipment for splicing waistlines of pull-ups

Abstract

The invention discloses equipment for splicing waistlines of pull-ups. The equipment comprises a frame body, a first compression roller body and a second compression roller body, wherein the frame body is of a rectangular frame structure; the first compression roller body is located above the second compression roller body; each of the first compression roller body and the second compression roller body is provided with a center pipe and a solid cylinder wall fixedly arranged outside the center pipe in a sleeving mode; a plurality of first compression tooth pieces are detachably installed on the cylinder wall of the first compression roller body; second compression tooth pieces used for being matched with the first compression tooth pieces are detachably installed on the second compressionroller body; a first driving device is installed on the frame body; the two ends of the center pipe of the first pressing roller body are in sliding connection with the frame body through connectingassemblies; and the two ends of the central pipe of the second compression roller body rotationally penetrate out of the frame body respectively. The equipment for splicing the waistlines of the pull-ups is simple in structure and stable in work, can improve efficiency and lower a defective rate, allows the joints of the waistlines of the pull-ups to be stably connected, saves material, and is reduced in cost.

Description

technical field [0001] The invention relates to the field of pull-up pants manufacturing equipment, in particular to a device for joining waists of pull-up pants. Background technique [0002] With the progress of society, personal hygiene is also gradually improved. Diapers and pull-up pants have become common personal hygiene products in daily life. Pull-up pants are loved by people because they look exactly like underwear and are easy to wear. Pull-up pants include baby pull-up pants and adult pull-up pants. Whether a pull-up pants is comfortable to wear mainly depends on the water-absorbing material of the pull-up pants and the circular waist part. During the production process of pull-up pants, the ring-shaped waist part is formed by hot pressing, so there will be two irons on the waist part of the finished pull-up pants, which correspond to the two sides of the waist of the human body. indentation. [0003] However, in the existing pull-up trousers production line,...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing pull-up trousers production line, the structure of the hot pressing equipment for the connection of the waistline of the pull-up trousers is complex, the work is unstable, and the pressure is often biased or not tight, resulting in an increase in the rate of defective products and increased cost input. , but also restricts the development of enterprises

[0004] In addition, in the existing pull-up trousers production line, the ironing teeth used to form the ironing marks on the joints of the waistline of the pull-up trousers are all arranged in a single row, so the connection of the joints of the waistline of the pull-up trousers is not stable. The tensile force that can withstand is limited, so it often breaks, causing the pull-up pants to be scrapped, especially for adult pull-up pants

In order to ensure a stable connection, the usual practice is to widen the width of the single row of hot indentations at the joints of the waistline of the pull-up pants. However, the surface of the indentations on the joints of the widened waistline is relatively hard, which is easy to scratch the waist of the human body.

At the same time, resulting in increased materials and increased cost input
