Description

Technical Field

[0001] This utility model relates to the field of dyeing and finishing equipment, and in particular to a guide roller for a washing machine. Background Technology

[0002] In textile dyeing and finishing, thorough washing with a washing machine is necessary to remove residual decomposition products, impurities, floating dyes, and other chemicals from scouring, dyeing, printing, and finishing processes. Taking cotton and linen fabrics as an example, during washing, the fibers absorb water and swell, and mechanical friction causes wrinkles and creases to easily form in the middle of the fabric. Wrinkling not only affects the quality of the finished product but can also lead to deviations in subsequent dyeing and printing processes. The guide roller in the washing machine, used for traction and fabric guidance, is a core component for fabric transport. Its performance directly affects the fabric's smoothness, abrasion resistance, and washing efficiency. Therefore, how to prevent wrinkling during washing by modifying the guide roller has become an important research topic. Utility Model Content

[0003] The purpose of this invention is to provide a guide roller for a washing machine.

[0004] The technical solution to achieve the purpose of this utility model is: a guide roller for a washing machine, which includes a roller body. Several rows of expansion units are arranged parallel and equally spaced along the circumference of the roller body on the outer wall of the roller body. The expansion units are located in the middle section of the roller body. The expansion unit includes a first convex ridge segment and a second convex ridge segment. The first convex ridge segment and the second convex ridge segment are both oblique lines. When the roller body is unfolded into a plane, the first convex ridge segment and the second convex ridge segment are mirror-symmetrical with respect to the outer wall line of the roller circumference corresponding to the axial center of the roller body. The first convex ridge segment and the second convex ridge segment are connected. The roller body on both sides of the expansion unit is a smooth cylindrical surface.

[0005] Furthermore, a third convex rib unit is provided on each side of the widening unit. Each third convex rib unit includes several third convex ribs arranged parallel to each other along the circumference of the roller body. The third convex ribs are parallel to the axial direction of the roller body, and each third convex rib connects to a first convex rib and a second convex rib on the same side. This novel wave pattern structure, with a central oblique spiral and straight sides, can prevent wrinkling while enhancing the washing effect of cotton and linen fabrics.

[0006] Furthermore, the first convex segment and the second convex segment are arc-shaped spiral segments, and the size of the spiral segment is limited to the effect of the fabric being peeled apart in the width direction when the fabric passes through the guide roller of the washing machine.

[0007] The expansion unit of the guide roller for the washing machine implemented in this utility model forms a new oblique mirror symmetric structure in the middle section of the roller body. In the washing machine, when the fabric passes through the guide roller and the guide roller rotates in the direction of expansion, the first convex section and the second convex section form an angle difference with the axial direction of the guide roller, which can peel the wrinkle-prone part in the middle of the fabric to both sides. The smooth roller part can avoid the formation of frilly edges on sensitive fabrics, making the fabric surface smooth and improving the washing quality. Attached Figure Description

[0008] Figure 1 This is a three-dimensional structural diagram of the guide roller for the washing machine described in Embodiment 1 of this utility model;

[0009] Figure 2 This is a schematic diagram of the main structure of the guide roller for the washing machine according to Embodiment 2 of this utility model. Detailed Implementation

[0010] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0011] like Figure 1 As shown, a guide roller for a washing machine includes a roller body 1. Several rows of expansion units 2 are arranged parallel and evenly spaced along the circumference of the outer wall 11 of the roller body 1. The expansion units 2 are located in the middle section of the roller body 1. The expansion unit 2 includes a first convex ridge segment 21 and a second convex ridge segment 22. The first convex ridge segment 21 and the second convex ridge segment 22 are both oblique lines. When the roller body 1 is unfolded into a plane, the first convex ridge segment 21 and the second convex ridge segment 22 are mirror-symmetrical with respect to the outer wall line of the roller circumference corresponding to the axial center of the roller body 1. The first convex ridge segment 21 and the second convex ridge segment 22 are connected. The roller body 1 on both sides of the expansion unit 2 is a smooth cylindrical surface.

[0012] In a washing machine, when the fabric passes through the guide roller of the washing machine and the guide roller rotates in an expanding direction, the first convex section and the second convex section form an angle difference with the axial direction of the guide roller of the washing machine, which can peel off the wrinkle-prone part in the middle of the fabric to both sides. The smooth roller part can prevent sensitive fabrics from forming frayed edges, making the fabric surface smooth and improving the washing quality of sensitive fabrics. Example 2

[0013] like Figure 2As shown, the difference between Embodiment 2 and Embodiment 1 is that the expansion unit 2 is provided with a third protruding rib unit 3 on both sides. The third protruding rib unit 3 includes several third protruding ribs 31 arranged parallel to each other along the circumference of the roller body. The third protruding ribs 31 are arranged parallel to the axial direction of the roller body 1, and each third protruding rib 31 is connected to the first protruding rib 21 and the second protruding rib 22 on the same side as the third protruding rib 31.

[0014] The new wave pattern structure with a diagonal spiral in the middle and straight lines on both sides can enhance the washing effect of cotton and linen fabrics while preventing wrinkles.

[0015] The first and second convex segments of this invention are not limited to oblique lines, but can also be arc-shaped spiral segments. The size of the spiral segments is limited to the effect of the fabric being peeled apart in the width direction when the fabric passes through the guide roller of the washing machine.

[0016] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent process transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
