Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller sleeve technology, specifically to a high-friction, torsion-resistant roller sleeve. Background Technology
[0002] Traditional roller sleeves are typically designed with a flat surface, resulting in low friction between the sleeve and the fabric, leading to poor drafting performance. To address this insufficient friction, some roller sleeves employ a surface with an uneven texture to increase friction. However, in actual production, the roller sleeve inevitably twists during operation. After twisting, the surface morphology of different sections of the sleeve in contact with the fabric changes, causing significant differences in friction across different parts of the sleeve. This inconsistency in friction interferes with uniform fabric drafting, affecting the drafting quality of the yarn. Therefore, this invention provides a high-friction, torsion-resistant roller sleeve. Utility Model Content
[0003] The purpose of this invention is to provide a high-friction, torsion-resistant roller sheath.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A high-friction, torsion-resistant roller sleeve includes: a roller sleeve body; the surface of the roller sleeve body is provided with a plurality of parallelogram grooves; the parallelogram grooves are evenly distributed along the circumferential direction of the roller sleeve body and spirally distributed along the axial direction of the roller sleeve body. The parallelogram groove is provided with diagonal protrusions; the diagonal protrusions are arranged along the diagonal of the parallelogram groove, and the diagonal protrusions in the parallelogram groove are connected as a whole to form a rib structure that is spirally distributed along the axial direction of the roller sleeve body.
[0005] Based on the above scheme and as a preferred embodiment of the above scheme, the width of the diagonal protrusion is smaller than the width of the protrusion between two adjacent parallelogram grooves.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme, the protrusion height of the diagonal protrusion is less than or equal to the depth of the parallelogram groove.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme, the edge of the parallelogram groove has an inclined structure.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme, the diagonally protruding edge has an inclined structure.
[0009] The beneficial effects of this utility model are: 1. This utility model has several evenly distributed parallelogram grooves on the surface of the roller sleeve, which can improve the friction of the roller sleeve, thereby increasing the stretching force on the fabric and ensuring the stability of the stretching.
[0010] 2. The parallelogram grooves on the surface of the roller sleeve of this utility model are spirally distributed along the axial direction of the roller sleeve body. At the same time, the diagonal protrusions are also spirally distributed along the axial direction of the roller sleeve body. When the roller sleeve is twisted under the action of force, the spirally distributed parallelogram grooves and diagonal protrusions can ensure that the surface structure of the roller sleeve changes little and ensure that its surface friction is stable. This avoids the situation where the stretching force of different sections of the roller sleeve is different, resulting in the fabric pieces being of different lengths, and reduces the impact of torsion on the stretching of the roller sleeve.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0015] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0016] like Figure 1 and Figure 2 As shown, a high-friction, torsion-resistant roller sleeve includes: a roller sleeve body 1, on the surface of which are formed a plurality of parallelogram-shaped grooves 2. The parallelogram-shaped grooves 2 are evenly distributed along the circumference of the roller sleeve body 1, and are also spirally distributed along the axial direction of the roller sleeve body 1.
[0017] A diagonal protrusion 3 is provided in the parallelogram groove 2. The diagonal protrusion 3 is arranged along the diagonal of the parallelogram groove 2 and is spirally distributed along the axis of the roller sleeve body 1. A group of diagonal protrusions 3 in the parallelogram groove 2 are connected as one, forming a rib structure spirally distributed along the axis of the roller sleeve body 1.
[0018] The width of the diagonal protrusion 3 is less than the width of the protrusion between two adjacent parallelogram grooves 2.
[0019] The height of the diagonal protrusion 3 is less than or equal to the depth of the parallelogram groove 2, so as to ensure that the top surface of the diagonal protrusion 3 does not protrude from the surface of the roller sleeve body 1.
[0020] The edges of the parallelogram groove 2 are inclined, and the edges of the diagonal protrusion 3 are also inclined. The inclined structure design makes the concave-convex junction of the roller sleeve body 1 surface have a gradient change, ensuring that the change from contact to non-contact between the roller sleeve body 1 surface and the fabric is gradient, making the change of force received by the fabric linear and the stretching more stable.
[0021] The parallelogram grooves 2 on the surface of the roller sleeve body 1 of this utility model are spirally distributed along the axial direction of the roller sleeve body 1. At the same time, the diagonal protrusions 3 are also spirally distributed along the axial direction of the roller sleeve body 1. When the roller sleeve is twisted during use, the spirally distributed parallelogram grooves 2 and diagonal protrusions 3 can ensure that the surface structure of the roller sleeve changes little, thereby ensuring that its surface friction is relatively stable. This avoids the situation where the stretching force of different sections of the roller sleeve is different, resulting in the stretching of the fabric pieces being of different lengths, and reduces the impact of torsion on the stretching of the roller sleeve.
[0022] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
[0023] Finally, it should be understood that some technical features in the embodiments may not be necessary for solving specific technical problems, and thus these technical features may be omitted or omitted without affecting the solution to the technical problem or the formation of the technical solution; moreover, the features, elements and / or functions of one embodiment may be appropriately combined, combined or coordinated with the features, elements and / or functions of one or more other embodiments, unless such combination, combination or coordination is obviously not feasible.
