Problems solved by technology

Since the pressing roller is a bare roller, it is easy to cause collision between the pressing roller and the drafting roller during the process of spinning the yarn, which will cause scratches on the surface of the drafting roller, making it easy to entangle
The collision between the two rollers is likely to generate sparks, causing unsafe factors; there are small circular grooves on the outer surface of the drafting rollers, which increase the friction between the tow and the drafting rollers, increase the cohesion, and can be used in the drafting process. When the roller is wound, it is easy to remove the waste silk on the roller with the help of small grooves; but because there are small circular grooves on the surface of the drafting roller, when the silk sheet is thin, there will be vibration between the drafting roller and the pressing roller, which will affect the bearing and Service life of the drafting shaft

Embodiment Construction

[0009] The present invention will now be further described in conjunction with specific examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.

[0010] like figure 1 The pressure roller structure shown includes a roller body 1, the surface of the roller body 1 is covered with an acid and alkali resistant rubber layer 2, and the hardness of the acid and alkali resistant rubber layer 2 is Shore hardness A85±5. The hardness of the rubber roller increases the contact area between the pressing roller and the drawing roller, and can protect the filament sheet when the fiber filament sheet is thin, remove moisture, and also play a role in shock absorption. The wear of the drafting roller is reduced, the winding of the drafting roller is reduced, and the quality of the silk sheet is improved.

[0011] Inspired by the above-mentioned ideal embodiment according to the present invention, through the above-me...

Abstract

The invention relates to a compression roller structure. The structure includes a roller body, and the roller body is coated with an acid-base resisting rubber layer with a Shore A value of 85 + / - 5.The compression roller structure has the advantages that wear of a drafting roller is reduced, wire wrapping of the drafting roller is decreased, and the quality of silk sheets is improved.

Description

technical field [0001] The invention relates to a pressure roller structure. Background technique [0002] The pressure roller of the viscose drafting machine is usually in the form of a bare roller (without glue), and its main function is to remove the moisture of the silk sheet and ensure the position of the drawing point of the silk sheet. The pressure roller is pressurized by the cylinder to ensure the pressure. Because the pressing roller is a bare roller, it is easy to cause the pressing roller to collide with the drafting roller during the thread spinning process, which will cause scratches on the surface of the drafting roller and cause it to be easily wound. The collision between the two rollers is likely to generate sparks, causing unsafe factors; there are small circular grooves on the outer surface of the drafting rollers, which increase the friction between the tow and the drafting rollers, increase the cohesion, and can be used in the drafting process. When th...
