Functional composite non-woven fabric preparation method and feeding method and device

Abstract

The invention discloses an inclined fastening feeding device. The top of a turnover feeding platform is a placing surface, the turnover feeding platform is rotated towards a lifting platform so that the lifting platform can move downwards, and a cloth roll on the placing surface can fall to the top of the lifting platform; the turnover feeding platform is rotated back to the lifting platform so that the lifting platform can move upwards until the cloth roll on the top of the lifting platform is opposite to aligning and fastening devices; and the two aligning and fastening devices are symmetrically distributed on two sides of the lifting platform, when two aligning roller bodies extend out to be aligned oppositely, two extrusion movable blocks extrude each other to move into inner cavitiesof the corresponding aligning roller bodies, and thus, a fastener partially extends out of the aligning roller bodies and abuts against the inner wall of a paper tube. The invention further disclosesa functional composite non-woven fabric preparation method, a feeding method and a feeding and conveying device. The inclined fastening feeding device has the advantage of improving the cloth production and processing efficiency.

Description

technical field [0001] The invention relates to the technical field of production and processing of non-woven fabrics, in particular to a preparation method of functional composite non-woven fabrics, a material feeding method and a device. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. [0003] As disclosed in patent application 2017100251910, a method for preparing a conductive-toughened melt-blown composite non-woven fa...

Problems solved by technology

[0009] The feeding and unwinding method of the prior art has the following disadvantages: since the feeding end of the feeding frame (unwinding frame) has a certain height, when the fabric is fed to the feeding frame, workers are required to put the cloth into place. There is a technical problem of laborious operation when the roll is lifted into the feeding station; for example, the air shaft is always inserted into the fabric after winding in the previous process, and each fabric roll needs to be equipped with an air shaft, resulting in high cost , and the weight of the air shaft itself is relatively large, which will undoubtedly increase the difficulty of the operation for workers to lift in. For example, insert the air shaft into the paper tube of the fabric roll, and then feed it into the feeding station. Although it overcomes the need for each fabric All rolls need to be equipped with an air-expanding shaft, which leads to high cost technical problems, but before feeding to the feeding station, there is an additional process of inserting the air-expanding shaft, and the technical problem of difficult operation for workers to carry in is not overcome ; Since the inflatable shaft and the frame are separated, after the fabric roll is fed to the feeding station, it is necessary to manually carry out fixed-point cooperation between the inflatable shaft and the frame to realize the inflatable shaft and the frame. The frame is rotated and coordinated or linked with the motor, and this high-position and heavy-load operation will undoubtedly further lead to poor operation convenience.

In this way, towels need to be changed frequently. Due to the large width of the rack, it is especially inconvenient to change towels without stopping the machine.
