Middle sealing mechanism for cylindrical forming of non-woven fabric

Abstract

The invention discloses a middle sealing mechanism for cylindrical forming of a non-woven fabric. The middle sealing mechanism is characterized by comprising a feeding table, a feeding guide wheel, a middle sealing table, an ultrasonic scalding and welding device and a discharging guide wheel, wherein the feeding table and the middle sealing table are arranged in tandem in the feeding direction; the feeding guide wheel is arranged above the feeding table in a rolling manner; the ultrasonic scalding and welding device is arranged above the middle sealing table; the middle sealing table is an independent element and comprises a die frame, a left supporting plate, a right supporting plate and a scalding and welding bottom wheel; the left and the right supporting plates are connected with the left and the right sides of the die frame; the distance between the left and the right supporting plates is adjustable; the left and the right supporting plates are used for propping a passing non-woven fabric cylindrical model open; the propping size is the cylindrical forming size of the non-woven fabric; and the scalding and welding bottom wheel is arranged in the middle of the die frame in a rolling manner and is arranged over against a scalding and welding head of the ultrasonic scalding and welding device. The middle sealing mechanism solves the technical difficult forming problems in single-side middle sealing for cylindrical forming of thin type non-woven fabrics and can be used for production of non-woven fabric decontamination funnel anti-clogging bags.

Description

technical field [0001] The invention relates to a non-woven fabric bag-making equipment which can be used for the production of non-woven fabric type scrubbing funnel anti-blocking bags, in particular to a non-woven fabric cylindrical forming middle sealing mechanism. Background technique [0002] The non-woven bags produced by the existing non-woven bag-making equipment generally have side seals and bottom seals, and the cloth is thicker (the weight is generally more than 30g per square meter), while the non-woven scrubbing funnel anti-blocking bag is a kind of Bags made of very thin non-woven sheets (generally weighing less than 15g per square meter) have a square shape with middle and bottom seals. They are mainly used in household products and hotel products, and are more popular abroad. Generally, there is basically no application in China. If the existing domestic non-woven fabric bag-making equipment is used for production, because the non-woven fabric sheet is very ...

AI Technical Summary

Problems solved by technology

If the existing domestic non-woven fabric bag-making equipment is used for production, because the non-woven fabric sheet is very thin, the non-woven fabric will appear in the forming process of the non-woven fabric from the sheet material to the single-sided middle seal of the cylindrical material. Poor sealing quality, easy tearing of the bag, and poor appearance quality of the scrubbing funnel anti-blocking bag made

Therefore, in order to produce non-woven scour funnel anti-blocking bags on the existing domestic non-woven bag-making equipment, the first problem is to solve the technical problem of forming thin non-woven fabrics from sheet materials to single-sided middle seals.
