Description
Technical Field
The utility model relates to a weaving roller washs technical field, especially relates to a sealed water spray cleaning device of weaving roller.
Background
The roller is a member for tensioning the yarn on the textile machine, a cylindrical rotating part in the textile machine which acts as a feed, draw, take-off thread, etc., and is a transliteration of the english word "roller", with the meaning of a roller and a shaft. Widely used for mechanisms of drafting, carding, conveying and the like of silk threads; the functions of the roller are divided into a drawing roller, a feeding roller, a compacting roller, a working roller and the like.
The drafting rollers are the main parts of the drafting mechanism of the spinning machine, and are paired by an upper roller and a lower roller to form a roller clamping opening for holding the sliver for drafting; the quality of the roller affects the uniformity of the output yarn, and the roller is usually referred to as a drafting bottom roller, which is a steel slender shaft with a groove, a knurling or a smooth surface on the excircle, and a plurality of single sections are connected into a whole column along the full length of the spinning machine and are actively driven by a driving mechanism.
The diameter of the spinning roller is suitable for the length of the spun fiber, the pressure of the upper roller and the bearing distance of the roller, and the spinning roller has enough bending resistance and torsional rigidity. Has correct groove tooth shape and specified surface finish, can effectively hold the fiber and does not damage or hook the fiber. The spinning device has high manufacturing precision and interchangeability, so that the spinning quality is ensured, and uneven sliver caused by mechanical factors such as roller eccentricity and bending is reduced. The surface is wear-resistant and tough in the center, is usually hardened by carburizing and hardening with steel No. 20 or steel No. 45, is made of chromium-molybdenum steel, and is sometimes subjected to surface treatment such as corrosion resistance and rust resistance.
The roller needs to be lubricated when the operation, and the initiative pivot needs to be lubricated, and in order to for the silk thread lubrication when the silk thread is towed simultaneously, also there is lubricating oil on the silk thread, and these lubricating oil can splash around in the arrangement box of roller under the high-speed rotation of roller, lead to the inside oil stain of roller box more, and these lubricating oil are all transparent, can not influence the rotation of roller by the clearance yet, also can influence the traction force and the direction of pulling to the silk thread to the roller.
Therefore, in the actual operation of equipment, need often to wash inside the roller box, generally 24 hours wash once, and oil stain adhesive force is stronger, need wash with the water of stronger pressure, can wash with high-pressure water beam again with the greasy dirt splash to farther scope, cause secondary pollution easily, need the clearance scope wider.
