Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of web-laying machine, specifically to a web-laying machine with flow guiding effect. BACKGROUND

[0002] The production equipment of non-woven fabric mainly includes an opener, a carding machine, a web-laying machine, and a needle punching machine or a water jet machine. The non-woven fabric is opened by the opener and supplied to the carding machine. The non-woven fabric after being carded by the carding machine is supplied to the web-laying machine for web laying. The web-laying machine transports the web through a screen curtain. After the web is well laid, it is transported to the needle punching machine or the water jet machine for needle punching or water jetting to form a non-woven product.

[0003] The web-laying device of the web-laying machine in the prior art includes an inclined curtain and a flat curtain for transporting the web. A compensation curtain is arranged at the lower side of the discharge end of the flat curtain. A ring curtain is arranged at the upper and lower sides of the compensation curtain. A pair of guide rollers is arranged below the discharge end of the ring curtain. The screen curtain moves onto the bottom curtain below the guide rollers after passing between the guide rollers. Finally, the web is transported to the next station through the bottom curtain. The device further arranges a guide roller between the ring curtain and the bottom curtain, which results in an excessively large distance between the ring curtain and the bottom curtain. The quality of the web is relatively light. When the web is rapidly transported, the web is easily lifted and wrinkled. When the web is reciprocally laid, the web is easily pulled by the web-laying device, which results in uneven ends of the laid web and unstable connection between the two layers of the web, and the forming effect is poor.

[0004] Due to the natural flow of fibers and the influence of aerodynamics, the fibers are unevenly distributed on the screen surface. This can cause some areas to be densely packed with fibers, while other areas are relatively sparse, which affects the uniformity of the subsequent processing process and the product.

[0005] Therefore, we propose a web-laying machine with flow guiding effect to solve the above problems. CONTENT OF THE UTILITY MODEL

The two groups of pressing units in the middle ensure that the web remains stable on the main transmission path, while the pressing units on the right side help to make the final arrangement after the web enters the fifth conveying belt, reducing wrinkles and deviation, improving the accuracy and quality of the laying.

[0011] Preferably, the surface of the pressing wheel is covered with a layer of polyurethane material, which has good wear resistance, elasticity and self-lubricating properties, can reduce the friction damage to the web, and at the same time increase the buffering effect during the pressing process, prevent the web from being deformed or damaged by excessive extrusion.

[0013] Preferably, the contact layer is made of rubber material, which has good elasticity and can effectively limit the movement range of the web without damaging it.

[0014] Preferably, the gas cylinder has two, respectively arranged at both ends of one side of the limiting plate, the double-cylinder design makes the movement of the limiting plate more stable and controllable, and can apply pressure more evenly to the web.

EMBODIMENT

[0029] On the basis of embodiment one, the flow guide mechanism further comprises a limiting unit, the limiting unit comprising a feeding roller 8, a limiting plate 9, a gas cylinder 901 and a contact layer 902, the feeding roller 8 being arranged above the left side of the conveying belt one 2 to assist the feeding process of the fiber web and ensure the stable entry of the fiber web into the conveying belt one 2. The limiting plate 9 is fixedly connected to the output end of the gas cylinder 901 on one side, and can be flexibly adjusted in the gap between the conveying belt one 2 and the limiting plate 9 by driving the gas cylinder 901, so as to limit the width of the fiber web and prevent deviation. The gas cylinder 901 is fixedly connected to the inner side of the connecting seat 301 to provide power and drive the limiting plate 9 to move, so as to adapt to fiber web materials of different widths. The contact layer 902 is fixedly connected to the other side of the limiting plate 9. The contact layer 902 is made of rubber material and can effectively limit the movement range of the fiber web without damaging the fiber web.

[0031] Working principle: place the fiber web on the conveying belt one 2, start the conveying belt, and the fiber web starts to be transmitted. The conveying belt one 2 serves as the initial transmission device of the fiber web, and is responsible for conveying the fiber web from the starting position to the subsequent processing area. In the transmission process, the pressing unit drives the bidirectional threaded rod 304 to rotate through the motor 302, so that the two screw nuts 305 drive the damping rods 306 and the pressing wheels 307 to move, thereby pressing the fiber web and ensuring the stability of the fiber web during the transmission process. The pressing wheel 307 made of polyurethane material reduces the damage to the fiber web.

[0032] Meanwhile, the limiting plate 9 in the limiting unit is driven by the gas cylinder 901 to flexibly adjust the gap between the limiting plate 9 and the conveying belt one 2, limit the width of the fiber web and prevent deviation. The contact layer 902 made of rubber material effectively limits the movement range of the fiber web without damaging the fiber web.
