Description

Technical Field

[0001] The utility model belongs to the technical field of rubber rollers, and particularly relates to a polyurethane rubber roller for textile use. Background Art

[0002] The rubber roller is an important component in industries such as textile and printing. The rubber roller generally includes a metal shaft and a rubber layer coated on the surface of the metal shaft. The metal shaft is usually a solid metal shaft. Therefore, in the case of a relatively large outer diameter of the rubber roller, such as greater than 15 mm, using a solid metal shaft has the following defects: the total weight of the relatively large metal shaft makes the rotational torque relatively large. Therefore, a relatively large power is required to drive the rubber roller to operate during the work of the rubber roller, resulting in relatively large power loss of the equipment. Moreover, the relatively large weight leads to relatively high logistics costs, and the relatively thick rubber layer causes excessive waste of this non-renewable material.

[0041] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present application.

[0042] Embodiment 1:

[0043] This embodiment provides a polyurethane rubber roller for textile use, including:

[0044] Roller shaft 1;

[0045] Rubber roller layer 2, and the rubber roller layer 2 is sleeved in the middle of the roller shaft 1;

[0046] Inner support plate 3, the inner support plate 3 is sleeved in the middle of the roller shaft 1, and the rubber roller layer 2 is fixedly arranged outside the inner support plate 3;

[0047] Inner support ring 4, several inner support rings 4 are axially equidistantly distributed on the roller shaft 1, and there is a gap formed between adjacent inner support rings 4;

[0048] Wherein the outer wall of the inner support ring 4 abuts against the inner support plate 3.

[0049] In this technical solution, the inner support ring 4 plays a good supporting role for the inner support plate 3 on the rubber roller, and the gap formed between the inner support rings 4 reduces the overall weight of the metal roller core of the rubber roller while ensuring the diameter of the roller core, so that it is both convenient for the handling and maintenance of the rubber roller and can reduce the power loss of the equipment. And the inner support plate 3 is supported by a metal material, and while ensuring the stability of the rubber roller layer 2 through the inner support layer, the thickness of the polyurethane rubber roller layer 2 is reduced to ensure the stable operation of the overall rubber roller.

[0050] Embodiment 2:

[0051] This embodiment provides a polyurethane rubber roller for textile use, in addition to including the technical solutions of the above embodiment, further having the following technical features.

[0054] The outer supporting portion 4b is integrally formed on the outer side of the inner supporting portion 4a, and the outer supporting portion 4b is in an isosceles trapezoid.

[0055] In this technical solution, the setting of the inner support portion 4a facilitates the connection between the inner support ring 4 and the roller shaft 1, while the setting of the outer support portion 4b can ensure that the inner support ring 4 can better support the inner support plate 3, and the outer support portion 4b is an isosceles trapezoid with a larger inner portion and a smaller outer portion, thereby ensuring that the inner support ring 4 can provide good support while reducing the mass brought by the inner support ring 4.

[0060] In this technical solution, the setting of the cut-in groove 4c can further reduce the mass of the inner support ring 4, and since the inner support ring 4 is set in the middle of the end face of the inner support ring 4 and extends inward, it ensures that the inner support ring 4 has a good support effect on the inner support plate 3 and greatly reduces the mass of the rubber roller core.

[0061] Example 4:
