Description

technical field [0001] The invention belongs to the technical field of finishing machinery after textile printing and dyeing, and in particular relates to an ironing roller for an ironing machine. Background technique [0002] In the textile printing and dyeing industry, it is usually necessary to iron the fabric in the finishing process, so as to improve the surface gloss, handle and appearance of the fabric, so as to improve the quality of the fabric. The ironing roller is an important part of the ironing machine, because whether the temperature of the ironing roller is uniform or not has a direct impact on the quality of the ironing effect of the fabric. [0003] The technical information about the ironing roller can be found in the published Chinese patent documents, such as document A), the authorized announcement number CN201473762U recommends "a new type of structure ironing roller body", which is an electric heater installed in the roller shell Tube support, a group...

AI Technical Summary

Problems solved by technology

[0004] The above document A) because the ironing roller is directly heated by a group of electric heating tubes distributed at intervals, there is a lack of uniformity in the temperature of the roller surface, and the temperature difference is about ±10°C. The temperature difference mentioned here refers to the ironing roller. The temperature at both ends is low and the temperature in the middle is high, and the electric heating tube directly heats the ironing roller, which consumes a lot of energy

[0005] Although the above-mentioned document B) can embody the technical effect mentioned in paragraph 0009 of its specification, it has the following shortcomings: First, the overall structure is relatively complicated, for example, in addition to the complex structure of the rotary power-connecting device itself, it is necessary to install the ironing roller (the patent name A core tube is added in the roller body), and multiple groups of coils are arranged between the core tube and the ironing roller, and a heat-insulating tube is set in the core tube, and the capacitor is set in the lumen of the heat-insulating tube and will be formed by The lines drawn from the coil (patents are called the starting wire and the end wire) are connected in series with the capacitor in the heat insulation tube, so it is not only troublesome to manufacture, but also complicated to assemble; second, it is prone to failure and affects the working efficiency of the ironing roller. Because once any of the coils and / or capacitors in the multiple groups (the patent cites three groups) of coils and the plurality of capacitors (the patent cites three) is damaged, the ironing roller will not be able to show the overall heating effect, and when it is necessary When replacing the faulty coil and / or capacitor, all the coils and capacitors can only be replaced together, or even the entire heat insulation tube is replaced together, which will not only cause lengthy downtime, but also increase the cost of equipment maintenance and use; The surface temperature of the smooth roller (usually around 170-180°C) is difficult to control; Fourth, it consumes a lot of energy

[0006] The above document C) has positive significance for improving the temperature uniformity of the ironing roller, but it is not safe because the connection between the oil circuit mechanism and the ironing roller is realized through a rotary joint, and the sealing effect of the rotary joint Generally relatively fragile, once the oil leaks, it is very easy to cause a fire, so the application of the ironing roller with this structure on the ironing machine is often avoided by the industry

In addition, it can be seen from the specification and drawings of this patent that it is often difficult to meet the desired effect of uniform temperature on the surface of the ironing roller by using an electric heating tube, and the energy consumption is large

[0007] The above-mentioned document D) because of the use of gas, although it has the effect of uniform temperature on the surface of the ironing roller, it is difficult to guarantee the safety, that is, it is inconvenient to be valued by the textile printing and dyeing industry due to the high risk. In particular, the competent departments of the textile industry and technical transformation management departments Even the fire department has a tendency to prohibit the use of gas to heat the ironing roller

[0008] The "ironing mechanism of the ironing machine" disclosed by the Chinese utility model patent authorization announcement number CN202969046U and the "ironing device of the ironing machine" disclosed by CN202969049U both have a significant effect of improving the temperature uniformity of the surface of the ironing roller body, and can also Energy saving is realized by reusing heat energy, but the overall structure of the ironing machine tends to be complicated due to the need for a hot air circulation device, and the overall structure of the heating device installed in the roller chamber of the ironing roller is also relatively complicated
