Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing machinery and equipment, and in particular to a medium-high guide roller. Background Technology

[0002] Traditional guide rollers are made by tightly fitting a rolled stainless steel outer layer to a rolled carbon steel inner layer. These rollers are relatively heavy, resulting in high resistance and energy consumption when used in flat-width washing machines. They are only suitable for washing general fabrics. When used with high-count, high-density, lightweight, or elastic fabrics, they easily cause wrinkling, stretching, and misalignment. Therefore, the development of guide rollers has become an important issue for improving fabric washing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a medium-high guide roller.

[0004] The technical solution to achieve the purpose of this utility model is: a medium-high guide roller, which is olive-shaped and includes a roller body. The surface of the roller body is provided with several long strip-shaped protrusions to form an undulating wave shape. Each of the protrusions is rotationally symmetrical about the central axis of the roller body. The two ends of the length direction of each protrusion extend to the two ends of the roller body. The vertical distance between the protrusion and the central axis of the roller body gradually decreases from the middle to the two ends.

[0005] Furthermore, the roller body is olive-shaped with the horizontal position in the middle slightly higher than the horizontal positions at both ends, and the curvature of each of the arc-shaped protrusions matches the curvature of the surface of the roller body.

[0006] Furthermore, the distance between the protrusion and the central axis of the roller gradually decreases from the middle to both ends of the roller.

[0007] Furthermore, the protrusion is arc-shaped.

[0008] Furthermore, the protrusion is V-shaped, and the included angle of the V-shape is obtuse.

[0009] The medium-high guide roller of this invention has an olive-shaped design with a high center and low ends, which allows the fabric to stay in the middle during washing, reducing the likelihood of the fabric shifting to one side and causing machine stoppage. When used as a guide roller under a water tank, the protrusions form waves in the water, impacting the fabric with the water flow, which can improve the washing effect and make the washed fabric cleaner. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the main structure of the high-pressure guide roller described in an embodiment of the present invention;

[0011] Figure 2 for Figure 1 Schematic diagram of the cross-sectional structure along the AA direction. Detailed Implementation

[0012] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0013] like Figure 1 and Figure 2 As shown, a medium-high guide roller includes a roller body 1. The roller body 1 is olive-shaped with the horizontal position in the middle slightly higher than the horizontal positions at both ends. The surface 11 of the roller body 1 is provided with several long strip-shaped protrusions 2 to form an undulating wave shape. Each of the protrusions 2 is rotationally symmetrical about the central axis of the roller body 1. The two ends of the length direction of each of the protrusions 2 extend to the two ends of the roller body 1. The vertical distance between the protrusions 2 and the central axis of the roller body 1 gradually decreases from the middle to both ends.

[0014] The medium-high guide roller is installed in the washing tank. Its olive-shaped design, with a high center and low ends, allows the fabric to stay in the middle during washing, reducing the likelihood of the fabric shifting to one side and causing machine downtime. When used as a guide roller under the tank, the protrusions create waves in the water, impacting the fabric and improving the washing effect, resulting in cleaner fabrics. Furthermore, fabrics prone to shrinkage and wrinkling are spread outwards by the medium-high roller, reducing the number of defective products caused by wrinkling.

[0015] When processing the medium-high guide roller, the stainless steel plate can first be pressed into an undulating wavy pattern, and then rolled into an olive shape with the horizontal position slightly lower than the horizontal positions at both ends through processes such as rolling. The medium-high guide roller obtained by this method weighs only 60% of that of the traditional guide roller, and the bending strength of the multi-directional wavy strips is not in one direction, so it is stronger and less prone to deformation than the traditional guide roller. However, the processing method of the medium-high guide roller of this utility model is not limited to this. Alternatively, the olive-shaped roller body can be made first, and then the strip-shaped protrusions can be welded and fixed to the surface of the roller body.

[0016] The roller body described in this invention is not limited to an olive shape, but can also be cylindrical. The outer contour of the medium-high guide roller is formed into an olive shape with the middle horizontal position slightly higher than the horizontal positions at both ends by the raised inclined shape.

[0017] The protrusion can be arc-shaped or V-shaped. When the protrusion is V-shaped, the included angle of the V-shape is obtuse, and it is preferable that the included angle is slightly less than 180°.

[0018] 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.
