Description

Technical Field

[0001] The present application relates to the technical field of textile equipment, and in particular to a spring steel sizing roller and a sizing machine with the spring steel sizing roller. Background Art

[0002] Sizing rollers are mostly made of stainless steel or rubber. Generally speaking, the performance of rubber sizing rollers is better than that of stainless steel sizing rollers. However, since most of the sizing rollers are immersed in the slurry when they are running, and the bottom is close to the heat source, the service life of the rubber sizing rollers is limited. Usually, the service life of domestic rubber sizing rollers is 1 year, and the service life of foreign ones is 4 years. If rubber sizing rollers are used, the one-time investment cost and subsequent maintenance cost of the equipment are both high. Stainless steel sizing rollers have a long service life and can be left unchanged for life. The uniformity of sizing will not be affected by damage, aging and other problems. However, due to their high thermal conductivity and fast heat transfer, they are prone to sizing spots and slurry stains. On the other hand, due to their inelasticity, their axial non-uniformity will lead to excessive pressure in local positions, which can easily concentrate the pressure on a few yarns and deform the yarn cross section.

[0003] Secondly, in order to adjust the sizing rate during online sizing, the sizing rate can be adjusted by adjusting the slurry flow rate, slurry concentration or the pressure of the sizing roller. Among them, the method of adjusting the sizing rate by adjusting the pressure of the sizing roller has the advantages of high precision, wide application range, good repeatability, automatic control and slurry saving. When the pressure of the sizing roller is adjusted, the extrusion width and extrusion strength between the sizing roller and the sizing roller change, thereby changing the slurry squeezed out of the sizing surface and changing the sizing rate. However, when the pressure is too high, it will affect the quality of some fibers, restrict the adjustment range of the pressure, and limit the adjustment range of the sizing rate. Summary of the invention

[0004] The present application proposes a spring steel sizing roller and a sizing machine with the spring steel sizing roller, wherein the sizing roller has the advantages of both a stainless steel sizing roller and a rubber sizing roller, has a longer service life and better sizing quality, and the sizing machine can flexibly adjust the extrusion strength and extrusion width, thereby increasing the adjustment range of the sizing rate.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a spring steel sizing roller, comprising a horizontally placed seamless steel tube and an outer cylinder, the outer cylinder being made of spring steel, a limiting unit and a support body being arranged between the seamless steel tube and the outer cylinder, the support body having elastic force, the outer wall of the support body being in close contact with the inner wall of the outer cylinder, the inner wall of the support body being in close contact with the outer wall of the seamless steel tube, so that the outer cylinder and the seamless steel tube always remain coaxial, the limiting unit comprising an assembly set, an annular water bag being installed on the assembly set, the annular water bag being filled with hydraulic oil, the annular water bag being not elastic, the annular water bag being connected to a servo valve via a connecting pipe, the filling degree of the hydraulic oil in the annular water bag being controlled by the servo valve, and then the maximum deformation of the upper part of the annular water bag being adjusted.

[0006] Furthermore, the assembly sets and annular water bags are provided in multiple groups and are distributed along the axial direction of the seamless steel pipe.

[0007] Furthermore, the two adjacent annular water bags and the first annular water bag and the servo valve are connected via a connecting pipe, and a control valve is provided on each section of the connecting pipe.

[0008] Furthermore, a water flow cavity is provided inside the seamless steel pipe, and water slip rings are provided at both ends of the water flow cavity. The two ends of the water flow cavity are connected to a constant temperature water circulation system through the water slip rings.

[0009] Furthermore, flanges are provided on both sides of the assembly sleeve, the side surfaces of the annular water bag are closely attached to the assembly sleeve, a heat-conducting film is provided on the surface of the annular water bag, and heat-conducting mud is smeared between the assembly sleeve and the seamless steel pipe.

[0010] Furthermore, both ends of the seamless steel pipe are provided with connecting heads, the inner end surface of the connecting head is tightly attached to the seamless steel pipe, the side wall of the connecting head is tightly attached to the outer tube, the thickness of the side wall is greater than the thickness of the outer tube, the connecting head and the seamless steel pipe are provided with a second sealing gasket, and a first sealing gasket is provided between the connecting head and the outer tube.

[0011] A sizing machine with a spring steel sizing roller comprises a machine body, on which a sizing roller, a sizing groove and a guide roller are mounted, and also comprises a spring steel sizing roller as claimed in claim 1.

[0012] Furthermore, two groups of lifting rollers are installed on the machine body, both groups of lifting rollers are closely attached to the surface of the outer cylinder, one group of lifting rollers is located directly below the outer cylinder, and the other group of lifting rollers is located on the side facing away from the sizing yarn.

[0013] Beneficial effects of this application:

[0014] The present application provides a spring steel sizing roller, the outer cylinder of which is made of metal, and has excellent aging resistance, high pressure resistance, wear resistance, corrosion resistance and other characteristics. It has a long service life and can maintain the stability of sizing for a long time. At the same time, due to its deformability and small temperature change, it can improve the uniformity of pressure distribution while reducing the generation of sizing spots and sizing stains, thereby improving the sizing quality and taking into account the advantages of stainless steel sizing rollers and rubber sizing rollers.

[0015] The present application provides a sizing machine with a spring steel sizing roller, which limits the deformation of the outer cylinder by the filling degree of hydraulic oil in the annular water bag, thereby limiting the extrusion width between the sizing roller and the squeezing roller, so that the extrusion width and extrusion strength under the same pressure can be flexibly adjusted, thereby increasing the adjustment range of the sizing rate.

The annular water bag 22 is connected to the servo valve 24 through the connecting pipe 23. The filling degree of the hydraulic oil in the annular water bag 22 is controlled by the servo valve 24. The inner wall of the annular water bag 22 is fixedly connected to the assembly sleeve 21, and the outer wall of the annular water bag 22 is fixedly connected to the inner wall of the outer tube 4.

The annular water bag 22 plays a role in limiting the deformation direction of the outer tube 4. The assembly sleeve 21 and the annular water bag 22 are provided with multiple groups, which are distributed along the axial direction of the seamless steel pipe 1. Multiple smaller annular water bags 22 limit the axial flow to avoid excessive deformation at local positions and excessive deformation at some positions.

[0028] See also Figure 5 The two adjacent annular water bags 22 and the annular water bags 22 and the servo valve 24 are connected through a connecting pipe 23. A control valve 25 is provided on each section of the connecting pipe 23.

[0032] Embodiment 2

[0033] See also Figure 6 A sizing machine with a spring steel sizing roller includes a body 14, on which a sizing roller 10, a sizing tank 11, a guide roller 12 and a spring steel sizing roller as in Example 1 are installed. A portion of an outer cylinder 4 is immersed in the sizing tank 11. After being immersed, the sizing yarn reaches between the sizing roller 10 and the spring steel sizing roller as in Example 1. The downward pressure of the sizing roller 10 can be adjusted to adjust the squeezed slurry, thereby adjusting the sizing rate.

[0034] Two groups of lifting rollers 13 are also installed on the machine body 14. The two groups of lifting rollers 13 are both in close contact with the surface of the outer cylinder 4 to provide support for the outer cylinder 4. One group of lifting rollers 13 is located directly below the outer cylinder 4, and the other group of lifting rollers 13 is located on the side facing away from the sizing yarn. The lifting rollers 13 are as close to the extrusion position as possible. If too many support bodies 3 are set, the deformation of the outer cylinder 4 will be affected. If the interval between the two support bodies 3 is too large, the degree of misalignment between the outer cylinder 4 and the seamless steel pipe 1 will increase in the local position. By setting the lifting rollers 13, the number of support bodies 3 used can be reduced while ensuring the coaxiality. The length of the outer cylinder 4 is greater than the length of the slurrying roller 10.

[0035] See also Figure 5 and Figure 6 By changing the filling degree of the hydraulic oil in the annular water bag 22, the maximum deformation of the annular water bag 22 is controlled, and then the deformation of the outer cylinder 4 is controlled, so that the maximum deformation of the outer cylinder 4 is consistent with the annular water bag 22. When the slurry squeezing roller 10 and the outer cylinder 4 are squeezed against each other, the deformation of the slurry squeezing roller 10 matches the deformation of the outer cylinder 4, and the extrusion width can be kept unchanged even if the pressure increases. When controlling the sizing rate, the extrusion strength and extrusion width can be adjusted independently, which improves the flexibility of adjustment.
