DETAILED DESCRIPTION

[0023] In order to make the purpose, method scheme and advantages of the embodiments of the utility model clearer, the method scheme in the embodiments of the utility model is clearly and completely described. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Example: Figure 1As shown, a web receiving device includes a frame 1, a web curtain 2, an active roller 3, a first driven roller 4, a second driven roller 5, a tensioning roller 6 and a moving mechanism for moving the tensioning roller 6, wherein the active roller 3, the first driven roller 4 and the second driven roller 5 are all connected to the frame 1, and the tensioning roller 6, the active roller 3, the first driven roller 4 and the second driven roller 5 are respectively arranged at the four corners of the longitudinal surface of the frame 1, the web curtain 2 is wound around the active roller 3, the first driven roller 4, the second driven roller 5 and the tensioning roller 6, the moving mechanism is connected to the tensioning roller 6, and the surface of the tensioning roller 6 is provided with a cleaning member for cleaning broken fiber fibers; the moving mechanism includes: a connecting rod 7, one end of which is connected to the tensioning roller 6; a collecting box 8, the other end of which is connected to the collecting box 8; a telescopic mechanism 9, the output shaft of which is hinged to the collecting box 8, and the output shaft of the telescopic mechanism 9 is vertically arranged.

[0025] In the specific implementation process, the cleaning element can be a brush. Figure 1 As shown, the upper nozzle 10 sprays the spinning liquid downward, and the spinning liquid is refined and deposited on the coagulation curtain 2 under the traction of the high-speed airflow. While the nozzle 10 is working, the coagulation curtain 2 is driven by the active roller 3, the first driven roller 4, the second driven roller 5 and the tensioning roller 6 to move, so that the spun fibers are evenly and continuously formed into a web on the coagulation curtain 2. After the web is formed, the non-woven fabric can be peeled and rolled up through existing equipment.

[0026] In order to accelerate the solidification and cooling of the fiber, Figure 1 As shown, a cooling device 11, such as an exhaust device or a blowing device, can be provided below the web-forming area of ​​the coagulating curtain 2. Preferably, an exhaust device can be used to prevent the fibers from falling off the coagulating curtain 2.

[0027] The active roller 3 is connected to a motor, and the motor drives the active roller 3 to rotate. The first driven roller 4 and the second driven roller 5 can be connected to the active roller 3 through a transmission device to achieve synchronous rotation, thereby improving the moving stability of the coagulating curtain 2. The transmission device can be a chain, a belt 20 or a gear.

[0028] The tension roller 6 can also be rotated synchronously with the active roller 3 through the aforementioned transmission device, but in order to improve the cleaning effect, there may be a speed difference between the tension roller 6 and the active roller 3, or the tension roller 6 may not rotate. More preferably, in order to avoid the non-rotation of the tension roller 6 causing a significant obstruction to the movement of the condensing curtain 2, a speed difference between the tension roller 6 and the active roller 3 is adopted, such as the speed of the tension roller 6 is greater than that of the active roller 3. In order to reduce energy consumption, the speed of the tension roller 6 may be less than that of the active roller 3.

[0029] The telescopic mechanism 9 can be a telescopic cylinder or a telescopic oil cylinder. The telescopic mechanism 9 drives the collection box 8 to move, and the collection box 8 drives the tension roller 6 to move. The tightness of the set state of the condensing curtain 2 can be adjusted by adjusting the position of the tension roller 6. Since the cleaning part is directly combined with the tension roller 6, no matter how the position of the tension roller 6 is adjusted, there is no need to adjust the position of the cleaning part additionally.

[0030] In order to realize the multi-purpose of the telescopic mechanism 9, the structure of the device is simpler and the manufacturing cost is lower. Figure 1 As shown, it includes: a slider 12, the slider 12 is hinged to the collection box 8; a slide rail 13, the slider 12 is slidably connected to the slide rail 13, the slide rail 13 extends along the length direction of the collection box 8, and the slide rail 13 and the telescopic mechanism 9 are respectively arranged at both ends of the collection box 8 in the length direction.

[0031] In the specific implementation process, the telescopic mechanism 9 can not only adjust the position of the tension roller 6, but also make the collection box 8 rotate around the slider 12 by telescoping to adjust the inclination degree and inclination direction of the collection box 8, so as to facilitate the discharge of the broken fibers in the box. The slide rail 13 and the telescopic mechanism 9 can be arranged on the frame 1, and the sliding connection method between the slider 12 and the slide rail 13 is the existing technology, which can be referred to Figure 2 In order to make the tension roller 6 have a larger displacement during the rotation of the collecting box 8, the connection position of the connecting rod 7 should be as far away from the slider 12 as possible.

[0032] The positional relationship among the slider 12, the slide rail 13 and the collection box 8 can be implemented in the following two ways.

[0033] Implementation method 1: Figure 2 As shown, the slide block 12 is connected to the bottom wall of the collection box 8 , and a space is reserved between the collection box 8 and the slide rail 13 for the collection box 8 to rotate.

[0034] During the specific implementation, it should be noted that if the bottom wall of the collection box 8 is too close to the slide rail 13 , the slide rail 13 will hinder the rotation of the collection box 8 . The distance between the collection box 8 and the slide rail 13 can be increased by increasing the height of the slider 12 .

[0035] Implementation method 2: Figure 3 As shown, the slide block 12 is connected to the side wall of the collection box 8 , and the vertical downward projection of the collection box 8 does not overlap with the slide rail 13 .

[0036] During the specific implementation process, the slider 12 is arranged on the side wall of the collection box 8, and at the same time controls the width of the slide rail 13, which makes it easier to achieve unimpeded rotation of the collection box 8 by the slide rail 13, without increasing the height of the slider 12 and wasting too much space. The device structure is more compact and smaller in size.

[0037] On the basis of implementation mode 1-2, in order to achieve the rotation speed difference between the tensioning roller 6 and the active roller 3, etc., this embodiment includes: a reducer, and any one of the active roller 3, the first driven roller 4, and the second driven roller 5 is connected to the tensioning roller 6 through the reducer.

[0038] In the specific implementation process, the speed of the tension roller 6 can be made smaller than the active roller 3, etc. through the speed reducer, so that the linear speed of the tension roller 6 is smaller than the linear speed of the coagulation curtain 2, which can improve the cleaning effect. In theory, the speed difference between the tension roller 6 and the active roller 3, etc. can also be achieved through an additional rotating motor, but the additional driving device will increase the manufacturing cost.

[0039] In this embodiment, a slag discharge door 19 is provided at one end of the collecting box 8 away from the sliding block 12 .

[0040] In the specific implementation process, the slag discharge door 19 can be an automatic door or a manual door. The collection box 8 can be made of a transparent material, such as hard PVC. When the collection box 8 is observed to be almost full, the collection box 8 is rotated by the telescopic mechanism 9 to tilt the collection box 8, and then the slag discharge door 19 is opened to discharge the slag.

[0041] like Figure 1 As shown, in this embodiment, it includes: a belt 20, and the active roller 3, the first driven roller 4 and the second driven roller 5 are connected by the belt 20 to achieve synchronous rotation.

[0042] During the specific implementation process, the chain, gears and belt 20 can all realize the synchronous rotation of the three rollers, but the fiber breakage in the working environment has a greater impact on the movement of the chain and gears. Therefore, the utility model selects the belt 20 to reduce the impact of fiber breakage and reduce the maintenance rate.

[0043] like Figure 1 As shown, in this embodiment, it includes: a lifting device 21, and the lifting device 21 is connected to the frame 1.

[0044] In the specific implementation process, the lifting device 21 can adopt a cylinder, and the distance between the coagulation curtain 2 and the nozzle 10 can be adjusted by the lifting device 21. The performance of the finished product can be adjusted by adjusting the receiving distance to meet different needs.

[0045] like Figure 1 As shown, in this embodiment, it includes: a base 22, and the lifting device 21 is arranged on the base 22; and a universal wheel 23, and the base 22 is provided with the universal wheel 23.

[0046] In the specific implementation process, the universal wheel 23 can be used to realize simple movement of the device.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
