Embodiment 1

[0057] see figure 1 ― Figure 9, a device for improving the quality of aramid non-woven fabric cotton web, including a hopper 71, a horizontal feeding curtain 70, a feeding roller 72, a humidifying roller 2 and a lower driving roller 20, the horizontal feeding curtain 70 The two ends are respectively provided with a front curtain roller 701 and a rear curtain roller 702. The feeding roller 72 includes an upper feeding roller 721, a lower feeding roller 722 and a feeding port 723 sandwiched between them. The feeding port of 70 and the bottom end of the hopper 71 are set facing each other. 7 are connected; the humidifying roller 2 includes a humidifying roller 21 and a roller shaft 22 passing through the middle thereof, and the humidifying roller 21 includes a middle rolling portion 24 and a left roller end connected to both ends thereof. 23. Right roller end portion 25, the middle roller pressing portion 24 includes a roller outer body 26 and a roller middle cavity 27, the ro...

Embodiment 2

[0060] The basic content is the same as that of Example 1, except that:

[0061] The hollow fan block 262 is a fan-shaped structure with a narrow top and a wide bottom; the cross section of the movable block 3 is a trapezoidal structure with a wide top and a narrow bottom, including the top side 31 of the block, the bottom side 32 of the block, and the top side of the block. The widths of the side 31 , the inner port 263 , the bottom side 32 of the block, the contact head 52 , and the upper top rod 51 are successively reduced.

Embodiment 3

[0063] The basic content is the same as that of Example 1, except that:

[0064] The two sides of the movable block 3 are respectively connected with the top end of the telescopic bar 4 , and the bottom end of the telescopic bar 4 is connected with the top of the solid sector block 261 on the side of the movable block 3 . The side part of the movable block 3 is provided with a movable ball cavity 42 with a one-way opening. The movable ball 41 set in the movable ball cavity 42 is connected with the top end of the telescopic strip 4, and the bottom end of the telescopic strip 4 passes through the ball cavity opening. After 43, it is connected to the top of the solid sector block 261, and the diameters of the movable ball cavity 42, the movable ball 41, the ball cavity opening 43, and the telescopic strip 4 are successively reduced.

Abstract

A device for improving the quality of aramid nonwoven cotton web, including a hopper, a horizontal feeding curtain, a feeding roller, a humidifying roller and a lower driving roller, the feeding port of the horizontal feeding curtain is directly opposite to the bottom end of the hopper Setting, the discharge port of the horizontal feeding curtain is connected with the net conveying curtain after passing through the feeding port, humidifying roller, opening roller, licker-in roller, cylinder and doffer in turn, and the humidifying roller includes a humidifying roller and a The roller shaft passing through the upper part, the outer body of the roller in the rolling part of the humidifying roller includes a solid fan block and a hollow fan block arranged at intervals one by one, wherein a movable block is embedded in the inner port of the hollow fan block , the top of the movable block is connected with the side wall of the roller shaft through the telescopic rod, and the bottom end of the movable block is connected with the contact head through the upper top rod, and the contact head is located outside the outer port of the hollow fan block. This design not only has a better effect of removing static electricity, but also is not easy to damage the product quality, which is beneficial to the smooth progress of fiber web formation.

Description

technical field [0001] The invention relates to a non-woven fabric manufacturing device, belonging to the technical field of textiles, in particular to a device and a using process for improving the quality of aramid non-woven fabric cotton webs, which are particularly suitable for enhancing the effect of removing static electricity, and are not easy to damage product quality. Background technique [0002] Aramid is a high-tech new material with high temperature resistance, flame retardant and insulating properties. It is currently the fastest growing high temperature resistant fiber variety in the world. It is widely used in high temperature filter materials and special protective clothing. However, since the aramid fiber is very fluffy, has high elasticity and high elongation, it is easy to accumulate static electricity during the weaving process. It will be easily entangled and easily blocked, increasing the difficulty of spinning, affecting the quality of the product, an...
