Non-woven cloth production line

Abstract

The invention discloses a non-woven cloth production line which comprises an opening device, a combing machine, a lapping machine, a needle-punching device and an uncoiler, wherein the opening device, the combing machine, the lapping machine, the needle punching device and the uncoiler are sequentially connected. The opening device comprises a first opening mechanism and a second opening mechanism, the first opening mechanism comprises a first opening machine and a first cotton conveying fan connected with the first opening machine, the second opening mechanism comprises a second opening machine and a second cotton conveying fan connected with the second opening machine, and a dust proof vibrating cotton box is disposed between the first opening machine and the second opening machine; the needle-punching device comprises a pre-needling machine, a reversing needling machine and at least one main needling machine, the pre-needling machine, the reversing needling machine and the at least one main needling machine are sequentially connected, the pre-needling machine and the main needling machine are respectively provided with an upper fulcrum parking portion, each upper fulcrum parking portion comprises an auxiliary transmission mechanism and a pneumatic mechanism, and the auxiliary transmission mechanism and the pneumatic mechanism of each upper fulcrum parking portion are arranged on one side of the machine frame. The production line is smooth in connection, and the surface of produced non-woven cloth is smooth, uniform in weight and thickness and good in air permeability.

Description

technical field [0001] The invention belongs to the field of textile machinery, in particular to a non-woven fabric production line. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. Low price, recyclable and so on. It is a non-woven fabric formed by directly using polymer chips, short fibers or filaments to form fibers through airflow or mechanically, and then undergo spunlace, needle punching, or hot rolling reinforcement, and finally finish finishing. [0003] The opening machine is an important equipment for the production of non-woven fabrics. Its function is to loosen the compressed raw cotton into smaller cotton blocks or cotton bundles, so as to facilitate the smooth progress of mixing and impurity removal. After the raw cotton is passed through the cotton blending machine, The raw cotton is sent to the cotton box machine through ...

AI Technical Summary

Problems solved by technology

The above-mentioned parking operation brings great inconvenience to the inspection or maintenance of the needle surface of the needle plate, and there will be safety hazards; in addition, the existing needle plate and the needle beam are connected by fastening bolts, which is inconvenient to install. Uneven stress on the needle plate, small contact area, and instability can easily lead to deformation of the needle plate and skewing of the needles, which seriously affects the quality of the needle loom. Moreover, it is necessary to replace the needle plate when the vehicle is parked to check the needle surface of the needle plate. When installing the needles on the needle, it is necessary to remove the fastening bolts one by one to remove the needle plate from the needle beam to complete the replacement of the needles. This disassembly method is time-consuming and laborious, and reduces the efficiency of needle replacement.
