Description

Technical Field

[0001] The utility model relates to the technical field of nonwoven fabric production, in particular to a spunlace double-sided jacquard device. Background Art

[0002] Spunlace nonwoven fabrics are made by spraying high-pressure fine water jets onto one or more layers of fiber webs, so that the fibers are entangled with each other, thereby reinforcing the fiber web and giving it a certain strength. The resulting fabric is a spunlace nonwoven fabric. The principle of reinforcing the fiber web by spunlace is similar to the needle punching process, but instead of using needles, multiple fine water jets generated by high pressure are used. Single-sided ordinary jacquard spunlace fabrics do not have a strong three-dimensional effect, and require double-sided jacquard spunlace to enhance the three-dimensional effect and improve the cleaning and wiping effect.

[0003] A Chinese patent with announcement number CN209468572U discloses a spunlace double-sided jacquard device, which has the function of fixing the non-woven fabric to be processed by means of the clamping mechanisms arranged at the ends of the two rotating shafts. In addition, the two clamping mechanisms are connected by a connecting rod, so that the two clamping mechanisms can be rotated by the operation of the driving mechanism. After the non-woven fabric to be processed rotates 180 degrees, the driving motor is turned off to achieve the effect of turning over the non-woven fabric, thereby solving the technical problem that the double-sided jacquard spunlace non-woven fabric cannot be produced in the prior art.

[0004] However, the above patent has the following shortcomings:

[0005] This device requires that the driving motor be manually turned off after the non-woven fabric rotates 180 degrees. There will be an error when shutting down, causing the rotation angle of the non-woven fabric to not be 180 degrees, thus affecting the jacquard effect. Utility Model Content
