Description

Technical Field

[0001] This utility model relates to the field of oscillating wire mechanisms, specifically an oscillating wire mechanism. Background Technology

[0002] Existing nonwoven fibers have poor transverse strength and insufficient uniformity due to their web-forming structure, and therefore need to be improved. Utility Model Content

[0003] The purpose of this invention is to provide a yarn-swinging mechanism to solve the problems mentioned in the background art, which has the advantages of effectively increasing the transverse strength of nonwoven fabric and the uniformity of the entire fabric surface.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a yarn swinging mechanism, including a nonwoven fabric stretcher, wherein multiple central pins are provided on the side of the nonwoven fabric stretcher, each central pin is sleeved with a connecting rod, the multiple connecting rods are connected to the same pull rod, one end of the pull rod is provided with a linkage mechanism for driving the pull rod to swing, and the lower end of the connecting rod is connected to a swing plate through a central pin.

[0005] By adopting the above technical solution, the linkage mechanism drives the pull rod to swing. The swing of the pull rod will drive the connecting rod to rotate around the central pin, which in turn drives the swing plate to swing. The swing plate causes the fibers to move laterally and overlap. This process is as follows: After the nonwoven fibers are stretched, they will move laterally and overlap after passing through the swing plate that swings back and forth. After the fibers move laterally and overlap, the lateral strength of the nonwoven fabric and the uniformity of the entire fabric surface are effectively increased.

[0006] As a further embodiment of this utility model: the linkage mechanism includes a motor, the output shaft of the motor is connected to an output disk, the output disk is connected to a first connecting rod, the end of the first connecting rod away from the output disk is connected to a second connecting rod, and the second connecting rod is connected to a pull rod.

[0007] By adopting the above technical solution, the output shaft of the motor rotates, which drives the output disk to rotate. After the output disk rotates, it drives the first connecting rod to rotate, which in turn drives the second connecting rod to rotate. The rotation of the second connecting rod will cause the pull rod to swing left and right.

[0008] Preferably, the nonwoven fabric fibers are drawn on the nonwoven fabric stretcher.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The linkage mechanism drives the pull rod to swing, and the swing of the pull rod will drive the connecting rod to rotate around the central pin, which in turn drives the swing plate to swing. The swing plate causes the fibers to move laterally and overlap. This process is as follows: After the nonwoven fibers are stretched, they will move laterally and overlap after passing through the swing plate. After the fibers move laterally and overlap, the lateral strength of the nonwoven fabric and the uniformity of the entire fabric surface are effectively increased. Attached Figure Description

[0016] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In this embodiment of the utility model,

[0018] A type of oscillating wire mechanism, such as Figures 1-4 As shown, it includes a nonwoven fabric stretcher 2. The nonwoven fabric stretcher 2 has multiple central pins 5 passing through its side. Each central pin 5 is sleeved with a connecting rod 4. The multiple connecting rods 4 are connected to the same pull rod 3. One end of the pull rod 3 is provided with a linkage mechanism 7 that drives the pull rod 3 to swing. The lower end of the connecting rod 4 is connected to a swing plate 6 through the central pin 5.

[0019] The linkage mechanism 7 includes a motor (not shown), the output shaft of which is connected to an output disk 8, the output disk 8 is connected to a first connecting rod 9, and the end of the first connecting rod 9 away from the output disk 8 is connected to a second connecting rod 10, which is connected to a pull rod 3.

[0020] The nonwoven fabric stretcher 2 stretches the nonwoven fabric fibers 1.

[0021] Working principle:

[0022] The linkage mechanism 7 drives the pull rod 3 to swing. The swing of the pull rod 3 will drive the connecting rod 4 to rotate around the central pin 5, which in turn drives the swing plate 6 to swing. The swing of the swing plate 6 allows the fibers to move laterally and overlap. This process is as follows: After the nonwoven fabric fibers 1 are stretched, they will move laterally and overlap after passing through the swing plate 6. After the fibers move laterally and overlap, the lateral strength of the nonwoven fabric and the uniformity of the entire fabric surface are effectively increased.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
