Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric rolling, in particular to a large-width non-woven fabric rolling and pressing mechanism. Background Art

[0002] In the existing non-woven fabric production and winding process, a tensioning device is often added to increase the tightness of the non-woven fabric winding. A certain tension is required under the tensioning device, and the non-woven fabric can withstand a certain deformation. However, the non-woven fabric has low elasticity, and if the tension applied to it is too large or too small, there will be various problems affecting the quality of the non-woven fabric winding. Therefore, the tension of the tensioning device needs to be adjusted, which is more troublesome and not suitable for the winding of large and wide non-woven fabrics.

[0003] In order to make the large-width non-woven fabric appear tight and not loose during the winding process, a certain uniform pressure must be applied to the non-woven fabric when it is rolled up, and the fabric should not be pulled while pressing the material, so as to ensure that the non-woven fabric is flat and does not deform. For this purpose, we provide a large-width non-woven fabric rolling and pressing mechanism. Utility Model Content
