Nonwoven fabrics, also known as nonwovens, are composed of oriented or random fibers. It is referred to as a cloth because of its appearance and certain properties. The non-woven fabric has the characteristics of moisture resistance, air permeability, flexibility, light weight, no combustion supporting, easy decomposition, no toxicity or irritation, rich colors, low price, recycling and the like. For example, the polypropylene (pp material) granules are mostly adopted as raw materials and are produced by a continuous one-step method of high-temperature melting, spinning, laying a line and hot-pressing coiling.
For example, patent application 2017100251910 discloses a method for preparing a melt-blown composite nonwoven fabric for electrical conductivity-toughening, which comprises the steps of compounding polymer melts in an extrusion stage to obtain differentiated spun fibers, and forming a fiber web on a web forming roller or a web forming curtain.
Still like the preparation of a melt-blown polyphenylene sulfide non-woven fabrics/aramid nanofiber composite diaphragm that patent application 201610171658.8 disclosed, through preparing into the suspension dispersion with the para-aramid nanofiber, the upper surface of coating melt-blown polyphenylene sulfide non-woven fabrics, the preparation melts the polyphenylene sulfide non-woven fabrics/para-aramid nanofiber composite diaphragm, the compound mode of coating of adoption.
Also, as disclosed in patent application 201310128380.2, a bacteriostatic non-woven fabric and a preparation method thereof are disclosed, wherein a polymer film-forming agent is coated on the non-woven fabric after the non-woven fabric is formed, so that the bacteriostatic effect of the non-woven fabric is improved, the bacteriostatic time is prolonged, and the real long-acting antibacterial effect is achieved. The adopted polymer film forming agent comprises the following raw materials in percentage by mass: 80-94% of high molecular polymer emulsion, 1-10% of bacteriostatic agent and 5-10% of auxiliary agent.
Further, as disclosed in patent application 201510251982.6, an electrostatic flocking type high-elastic sound-absorbing flame-retardant melt-blown nonwoven fabric and a manufacturing method thereof are disclosed, wherein an upper adhesive film and a lower adhesive film are coated on the opposite surfaces of an upper melt-blown base fabric and a lower melt-blown base fabric, and are dried and wound to prepare the electrostatic flocking type high-elastic sound-absorbing flame-retardant melt-blown nonwoven fabric, wherein a plurality of layers of fabrics are glued and compounded. Therefore, how to provide the functions of the non-woven fabric and improve the performance of the non-woven fabric has great market value.
The processing method of the composite fabric in the prior art generally comprises the steps of feeding the fabric through a feeding device, conveying the fabric to a rear path under the guidance of a material guide roller and a traction roller until the fabric is fed to a gluing roller or a coating device to be compounded or coated on the surface layer of the fabric, drying the fabric, and winding and discharging the fabric in a winding device.
At present, the traditional fabric feeding mode is to lift a fabric roll with an air expansion shaft to a feeding rack, and air flow is introduced into the air expansion shaft after the air expansion shaft is bonded with an output shaft of a motor or the air expansion shaft is rotationally connected with the rack, so that the air expansion shaft tensions a paper tube in the fabric roll, and the fastening of the fabric roll is realized. The patent application 201611142933.X discloses a synchronous initiative unwinding device of carbon fiber cloth, wears cloth on the inflatable shaft, and the inflatable shaft is connected in the frame through the inflatable shaft support at both ends, and the initiative unwinding servo motor is arranged at one end of the inflatable shaft side, and the initiative unwinding servo motor can drive the inflatable shaft to rotate through the gear transmission of the inflatable shaft.
The feeding and unreeling mode in the prior art has the following defects: because the feeding end of the feeding frame (unwinding frame) has a certain height, when the fabric is fed into the feeding frame, workers are required to lift the fabric roll into a feeding station, and the technical problem of labor-consuming operation exists; if the air expansion shaft is always inserted into the fabric wound in the previous process, and each cloth roll needs to be provided with the air expansion shaft, the cost is high, the self weight of the air expansion shaft is large, and the operation difficulty of lifting the worker is increased undoubtedly, if the air expansion shaft is firstly inserted into a paper tube of the cloth roll and then fed into a feeding station, the technical problem of high cost caused by the fact that each cloth roll needs to be provided with the air expansion shaft is solved, but the process of inserting the air expansion shaft is added before the cloth roll is fed into the feeding station, and the technical problem of high operation difficulty caused by the fact that the worker lifts the cloth roll is not solved; because the inflatable shaft and the frame are separated, after the cloth roll is fed to the feeding station, fixed-point matching operation between the inflatable shaft and the frame needs to be carried out manually, the inflatable shaft can be in running fit with the frame or linked with a motor, and the operation of high-position heavy load undoubtedly leads to poor convenience of operation.
In addition, when the fabric is conveyed, especially in a dry environment or an air conditioning system which is conventionally arranged in a factory cannot meet the requirement of specially eliminating static electricity in the processing process of a certain fabric, a humidifying device needs to be arranged on a conveying path of the fabric. At present, a mode of humidifying towels on a conveying path is mostly adopted in a factory to humidify fabrics. In this way, the towel needs to be replaced frequently, and because the width of the rack is large, the towel is particularly inconvenient to replace without stopping the machine.

By utilizing the flexible deformability of the rubber layer, on one hand, the friction coefficient between the paper tube and the cam is improved after the convex part is pressed against the inner wall of the paper tube; on the other hand, rigid or pointed contact between the convex part and the inner wall of the paper tube is avoided. The rubber layer at the end part of the extrusion movable block can reduce the impact force when the two extrusion movable blocks are contacted.
Furthermore, a splicing structure or a mortise and tenon matching structure is formed by utilizing concave-convex structures which are matched with each other, so that the firmness of the two closing roller bodies which form a whole body after closing is ensured, and the movement synchronism of the two closing roller bodies is further realized. When the closing roller bodies are used as the driving source, the consistency that the two closing roller bodies synchronously rotate can be met only by arranging the motor on one of the closing roller bodies.
Further, when the cloth roll needs to be unwound by taking the closing roller body as an active driving source or by taking the closing roller body as an active driving source to assist in being matched with winding of a subsequent winding device to unwind the cloth roll, the closing roller rotation driving device is arranged, after the closing roller body extends out to a closing position, a second discharging gear is fixedly sleeved on the closing roller body and moves to a position meshed with the first discharging gear, and the discharging driving motor is started to rotate to drive the first discharging gear to rotate so as to drive the second discharging gear to rotate, so that the closing roller body rotates. Therefore, the additional operation of bonding or interference fit of the roller and the output end of the motor is completely eliminated when the active unwinding of the cloth roll is required to be realized as in the prior art.
