Heating roller body for spandex spinning machine

Abstract

The invention discloses a heating roller body for a spandex spinning machine. The heating roller body comprises a roller shaft and a roller connected to the roller shaft through a fixing member, openings are formed in both ends of the roller, the roller shaft is screwed into the openings through the fixing member, a groove is formed in the outer surface of the roller and internally provided with athermal conduction buffer layer and a soft brush layer, and a steam channel is formed in the roller and includes an air intake passage, an air outlet passage and a heating passage for communicating the air intake passage with the air outlet passage, wherein the air intake passage and the air outlet passage are located at the openings; the heating passage is located on the inner surface of the roller and used for providing heat to the thermal conduction buffer layer and is parallel to the thermal conduction buffer layer; a constant-temperature heating plate is arranged on the surface of the side, away from the thermal conduction buffer layer, of the heating passage and used for controlling the temperature of steam in the heating passage. The heating roller body has a simple structure and high heating efficiency.

Description

technical field [0001] The invention relates to the technical field of spandex yarn production, in particular to a heating roller body for a spandex spinning machine. Background technique [0002] At present, during the spinning process, the spinning machine often processes the spandex yarn through heating rollers, so as to improve the quality, smoothness and softness of the spandex yarn. In traditional spinning equipment, the surface of the press roll is usually heated outside it. However, when people use it, it is found that this type of equipment usually has the following defects: one, only the local heating of the surface of the pressing roller is very easy to make the temperature of the pressing roller at the processing place of the yarn too low or unstable; The rollers are in a non-uniform heating state for a long time, so that the service life of the pressure rollers is greatly reduced, thereby increasing the production cost. [0003] In addition, in the prior art, ...

Problems solved by technology

However, when people use it, it is found that this type of equipment usually has the following defects: one, only the local heating of the surface of the pressing roller is very easy to make the temperature of the pressing roller at the processing place of the yarn too low or unstable; The rollers are in the uneven heating state for a long time, which greatly reduces the service life of the pressure rollers, which leads to an increase in production costs

[0003] In addition, in the prior art, the roller body of the spandex spinning machine usually does not have the elastic cushioning function

Therefore, in the actual manufacturing process of the spandex spinning machine, the spandex yarn on the surface of the roller body of the textile machine will often cause the problem of spandex yarn breakage due to excessive tension, and the spandex yarn on the surface of the roller body will be difficult to obtain due to excessive tension. take it down
