Description

Technical Field

[0001] This utility model relates to the field of conveyor roller technology, specifically to a conveyor roller assembly mechanism for a nonwoven fabric winding machine. Background Technology

[0002] After the nonwoven fabric is produced, it needs to be wound and packaged by a winding machine. Throughout the entire process from the nonwoven fabric production equipment to the winding machine, conveyor rollers are required for transport. During the conveying process, to ensure that the nonwoven fabric is neatly and attractively wound up by the winding machine, it is necessary to ensure that the nonwoven fabric is transported along the centerline of the conveyor route.

[0003] Existing technologies include relatively advanced silicone strip spreading rollers, used to stretch nonwoven fabric to both sides during conveying, preventing lateral wrinkles that could lead to uneven winding and internal creases in the nonwoven product. However, these rollers have complex internal structures and processes, requiring computer control and parameter adjustments for different nonwoven fabric models. Furthermore, they are expensive, require a large number of rollers throughout the conveying process, and are costly to replace. To address these issues, our company has designed a nonwoven fabric conveying roller assembly with a simple structure and lower cost. Utility Model Content

The upper pressure roller and the front pressure roller are both stainless steel smooth rollers, and the support roller is a rubber-coated roller with a rubber sleeve on its surface, and the rubber sleeve is also provided with guide grooves inclined to both sides symmetrically on the left and right.

[0007] Preferably, the idler roller is mounted on the fixed frame via a fixed shaft seat one, the upper pressure roller is mounted on the fixed frame via a vertically sliding movable shaft seat, and the front pressure roller is mounted on the front of the fixed frame via a fixed shaft seat two.

[0008] Preferably, a vertical guide rod is installed between the top of the movable shaft seat and the fixed frame, and a compression spring sleeved on the outside of the guide rod is also installed between the top of the movable shaft seat and the fixed frame.

[0009] Preferably, a guide sleeve is installed on the fixing frame at the position corresponding to the guide rod.

[0010] Preferably, the corresponding included angle between the upper compression roller and the front compression roller and the roller shaft of the supporting roller is 90-100°.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The upper compression roller and the front compression roller are used for pressing the non-woven fabric on the surface of the supporting roller, the friction between the upper compression roller and the front compression roller and the non-woven fabric is small, the friction between the supporting roller and the non-woven fabric is large, the non-woven fabric is stretched to two sides through the left-right symmetrical guide grooves of the rubber sleeve during the conveying of the non-woven fabric and the rotation of the supporting roller, the upper compression roller and the front compression roller, so that the two sides of the non-woven fabric are subjected to transverse tension at the same time to eliminate internal wrinkles, the effect of smoothing the non-woven fabric during conveying is achieved, and the utility model has the advantages of simple structure, convenient use, low cost and suitability for popularization and use.
