Olive-shaped fuzzing roller

Abstract

The utility model discloses an olive-shaped fuzzing roller which comprises an oval roller body with a large middle and two small ends and roller shafts arranged at the two ends of the oval roller body, the long axis of the oval roller body is arranged along the axis of the roller body, and spiral grooves used for guiding cloth to unfold from the middle to the two ends are symmetrically formed in the two ends of the oval roller body. Due to the fact that the oval roller body with the large middle and the two small ends is arranged, the edge center difference is effectively improved, and fuzzing narrowing is reduced; by arranging the spiral groove, the fluffing effect is achieved, cloth can be prevented from being stacked in the fluffing process, and the fluffing efficiency is further improved.

Description

Technical Field

[0001] The utility model relates to a textile processing machine, in particular to an olive-shaped raising roller. Background Art

[0002] The existing raising roller is a cylindrical roller body, and multiple raising is achieved through the groove body on the outer surface of the roller body. After multiple raising, due to the warp tension of the fabric and the action of the raising roller, there is a tendency to shrink, and the raising uniformity is lacking. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an olive-shaped raising roller with reasonable design, simple structure, reduced shrinkage and good raising uniformity in view of the deficiencies of the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An olive-shaped raising roller is characterized in that it includes an elliptical roller body which is large in the middle and small at both ends and roller shafts arranged at both ends of the elliptical roller body, the major axis of the elliptical roller body is arranged along the axis of the roller body, and spiral grooves for guiding cloth to unfold along the two ends are symmetrically arranged at both ends of the elliptical roller body, and the rotation directions of the two spiral grooves are opposite.

[0006] The technical problem to be solved by the utility model can also be achieved through the following technical solution: the spiral groove extends from the middle position of the elliptical roller body to both ends, thereby improving the spreading effect during the raising process.

[0007] The technical problem to be solved by the utility model can also be achieved through the following technical solution, in which the pitch of the spiral groove gradually decreases from the center position of the elliptical roller body to both ends to ensure the anti-shrinkage effect of the cloth at both ends of the roller body.

[0008] The technical problem to be solved by the utility model can also be achieved through the following technical scheme: the eccentricity of the elliptical roller body is 0.7-0.95, the larger the eccentricity, the flatter the ellipse is, so as to avoid the elliptical roller body being too round and making it difficult to accurately control the raising effect; the width of the spiral groove is 20-30mm, so as to ensure the raising and spreading effects.

[0009] Compared with the prior art, the utility model provides an elliptical roller body that is large in the middle and small at both ends, which effectively improves the edge-to-center difference and reduces the nap shrinkage; by providing a spiral groove, it not only has a napping effect, but also can avoid the stacking of cloth during the napping process, further improving the napping efficiency.

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0013] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0014] Reference Figure 1 An olive-shaped raising roller comprises an elliptical roller body 1 which is large in the middle and small at both ends and roller shafts 2 arranged at both ends of the elliptical roller body 1, the major axis of the elliptical roller body 1 is arranged along the axis of the roller body, and spiral grooves 3 for guiding the cloth to unfold along the two ends are symmetrically arranged at both ends of the elliptical roller body 1, and the spiral directions of the two spiral grooves 3 are opposite; the spiral groove 3 extends from the middle position of the elliptical roller body 1 to both ends; the pitch of the spiral groove 3 gradually decreases from the center position of the elliptical roller body to both ends, the angles at both ends of the elliptical roller body are 0.05°-0.3°, the width of the spiral groove is 20-30mm, and the groove width of the overall spiral groove is equal.

[0015] The olive-shaped raising roller of the utility model is provided with an elliptical roller body which is large in the middle and small at both ends. During the raising process, different forces are applied to the fabric from the middle to the two sides, thereby improving the edge-to-center difference and reducing the raising shrinkage. That is, according to the different pressures between the fabric and the roller body, the tension of the fabric in the warp direction is different, thereby avoiding the shrinkage tendency on both sides after the raising, thereby ensuring the uniformity of the raising and further improving the raising effect.

[0016] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
