背景技术Background technique
近年来，全球对水刺无纺布需求越来越大，应用越来越广泛，在中国水刺无纺布需求更是高速增长，大众对无纺水刺布的制作工艺、用途等提出了越来越高的要求，促使国内各大无纺水刺布生产厂家对水刺设备提出了更苛刻的要求。抽吸辊筒的具体作用是在水刺头和负压抽吸的共同作用下，将已经梳理、铺网并形成一定工艺要求的纤维网纠缠加固定型，进而初步形成水刺布。In recent years, the global demand for spunlace non-woven fabrics has been increasing and its applications have become more and more extensive. In China, the demand for spunlace non-woven fabrics has grown rapidly. The higher and higher requirements have prompted the major domestic non-woven spunlace manufacturers to put forward more stringent requirements for spunlace equipment. The specific function of the suction roller is to entangle and fix the fiber web that has been carded, laid and formed with certain technological requirements under the joint action of the spunlace head and negative pressure suction, and then initially form the spunlace fabric.
现有技术的直轴式抽吸辊筒主体（即抽吸管9’，参见图1、2所示）为一根完整钢管，此装置虽然结构简单，但是由于工作区域直径小，导致导流板2厚度大，水流经过负压抽吸口的行程长，耗能较高，抽吸效率低、效果差等问题，越来越不能满足高速发展的无纺布行业。The main body of the direct-axis suction roller in the prior art (that is, the suction pipe 9', as shown in Figures 1 and 2) is a complete steel pipe. Although the structure of this device is simple, due to the small diameter of the working area, it leads to diversion The plate 2 has a large thickness, long stroke of water flow through the negative pressure suction port, high energy consumption, low suction efficiency, poor effect and other problems, which are more and more unable to meet the high-speed development of the non-woven fabric industry.

The working area part of the present invention uses a large-diameter stainless steel suction pipe as the cylinder body, and the transmission part and the fixed part still use small-diameter stainless steel suction pipes as the cylinder body. The two parts are connected by flanges, and the rest of the structure is matched around the cylinder , its structure is stable, energy-saving and high-efficiency, safe and stable in operation, its shape and installation size remain unchanged, and it can directly replace the existing technology for installation and use. The outer filter screen part of the present invention adopts a three-layer net structure supported by punched steel net, and the net type can be replaced according to the user's technological needs.
本发明的目的可通过以下措施来实现：The object of the present invention can be achieved through the following measures:
本发明的高效节能分体式抽吸辊筒包括以共轴线方式通过连接法兰对接在一起的大直径不锈钢抽吸圆管和小直径不锈钢抽吸圆管，所述小直径不锈钢抽吸圆管的外延端与负压抽吸装置相连接，所述大直径不锈钢抽吸圆管的外延端与通过密封端板与轴头相固接；所述轴头的外延端通过轴承、轴承座与用于安装外复合圆网的轴端密封端板相固接；在所述小直径不锈钢抽吸圆管与大直径不锈钢抽吸圆管对接端的管壁上的由同步带轮、滚动轴承、环形底座、内侧密封环板（即传动法兰）共同构成套架，所述同步带轮通过滚动轴承与环形底座相结合，并用定位环固定滚动轴承，且所述同步带轮内侧通过连接件与内侧密封环板（即传动法兰）的侧面相结合；所述外复合圆网的两端通过便于拆装的连接件分别与轴端密封端板的外圆面、内侧密封环板（即传动法兰）的外圆面相结合；在所述大直径不锈钢抽吸圆管的管壁上加工有贯穿管壁的作为负压抽吸口的长圆孔，在长圆孔两端、外复合圆网与大直径不锈钢抽吸圆管的外壁之间的环腔内设置有带有抽吸口的导流板。The high-efficiency and energy-saving split suction roller of the present invention includes a large-diameter stainless steel suction pipe and a small-diameter stainless steel suction pipe that are butted together in a coaxial manner through a connecting flange, and the small-diameter stainless steel suction pipe The extension end is connected with the negative pressure suction device, and the extension end of the large-diameter stainless steel suction pipe is fixedly connected to the shaft head through the sealing end plate; the extension end of the shaft head is connected to the shaft head through the bearing and the bearing seat The shaft end sealing end plate of the outer composite cylinder is installed and fixed; on the pipe wall of the butt joint end of the small-diameter stainless steel suction pipe and the large-diameter stainless steel suction pipe, there are synchronous pulleys, rolling bearings, ring bases, inner The sealing ring plate (that is, the transmission flange) together forms a sleeve frame. The synchronous pulley is combined with the annular base through a rolling bearing, and the rolling bearing is fixed with a positioning ring, and the inner side of the synchronous pulley is connected to the inner sealing ring plate (ie The two ends of the outer composite cylinder are respectively connected to the outer circle of the shaft end sealing end plate and the outer circle of the inner sealing ring plate (that is, the transmission flange) through connectors that are easy to disassemble. Surfaces are combined; on the pipe wall of the large-diameter stainless steel suction pipe, there is a long round hole that runs through the pipe wall as a negative pressure suction port. A deflector with a suction port is arranged in the annular cavity between the outer walls of the tube.
本发明中所述导流板与大直径不锈钢抽吸圆管管壁相固接，并用密封胶密封。所述外复合圆网为采用冲孔钢板网作为支撑的三层网结构。In the present invention, the guide plate is fixedly connected with the wall of the large-diameter stainless steel suction pipe, and is sealed with a sealant. The outer composite cylinder is a three-layer mesh structure supported by punched steel mesh.
本发明采用的导流板厚度小，回收的水可快速通过导流板的抽吸口，进入负压腔内，减少抽吸口壁对能量的损耗。The deflector used in the present invention has a small thickness, and the recovered water can quickly pass through the suction port of the deflector and enter the negative pressure cavity, thereby reducing energy loss on the wall of the suction port.
本发明的工作原理如下：The working principle of the present invention is as follows:
纤网在经过水刺头时，通过高压产生的高速水针首次穿过纤网，撞击到抽吸辊筒表面上的外复合圆网，会产生各个角度、各个方向、多次的反射，形成的高速水流带动纤网中的纤维缠结加固初步成布，能量耗尽的水流，在辊筒负压的作用下，通过抽吸口进入辊筒被抽离进入水处理系统，循环利用。与此同时，纤网贴在辊筒外复合圆网上，随之一起转动，到达第二个水刺头，水针再次通过纤网撞击外网，进一步带动纤维缠结，均匀地对布面加固。以此类推，不断经过水刺头，通过水针加固布面，达到客户所需要的质量。三只水刺头围绕一只抽吸辊筒配装，换而言之，纤网通过一个辊筒最多可以被水针加固三次，一台水刺机可以根据需要装配配多只抽吸辊筒。另外，根据不同的外网网格形状、材料，可以产生不同的布面花型。辊筒的外网可以根据需要进行更换，以达到所需要的布面花型。When the fiber web passes through the hydroentanglement head, the high-speed water needle generated by high pressure passes through the fiber web for the first time, and hits the outer composite cylinder on the surface of the suction roller, which will produce multiple reflections at various angles and directions, forming The high-speed water flow drives the fiber entanglement and reinforcement in the fiber web to initially form a cloth, and the energy-exhausted water flow, under the action of the negative pressure of the roller, enters the roller through the suction port and is drawn into the water treatment system for recycling. At the same time, the fiber web is attached to the composite circular net outside the roller, and rotates together with it to reach the second spunlace head. The water needles pass through the fiber web and hit the outer web again, further driving the fiber entanglement, and evenly reinforcing the cloth surface. . By analogy, through the spunlace head continuously, the cloth surface is reinforced by water needles to achieve the quality required by customers. Three hydroentanglement heads are assembled around one suction roller. In other words, the fiber web can be reinforced by water needles three times at most through one roller. One hydroentanglement machine can be equipped with multiple suction rollers as required. . In addition, different fabric patterns can be produced according to different mesh shapes and materials. The outer net of the roller can be replaced as needed to achieve the desired fabric pattern.
本发明的有益效果如下：The beneficial effects of the present invention are as follows:
本发明配合高压水刺头成布质量强度更高，抽吸效率更高，其结构更稳定，加工简单，节能性能更高，废水回收更便捷，精度容易保证，封闭性能良好，运行安全可靠。它的推广，可在一定程度上进一步降低能耗，提高布面花型清晰度，增加拉伸强度，延长辊筒使用寿命，降低设备的维护成本。提高生产效率和产品品质，从而提升整条水刺生产线的技术水平。The invention cooperates with the high-pressure water thorn head to form cloth with higher quality strength, higher suction efficiency, more stable structure, simple processing, higher energy-saving performance, more convenient waste water recovery, easy guarantee of precision, good sealing performance, and safe and reliable operation. Its promotion can further reduce energy consumption to a certain extent, improve the clarity of cloth patterns, increase tensile strength, prolong the service life of rollers, and reduce equipment maintenance costs. Improve production efficiency and product quality, thereby improving the technical level of the entire spunlace production line.
