Description

A kind of godet

Technical field

This utility model relates to electromagnetic heater, in particular it relates to a kind of godet adopting Electromagnetic Heating.

Background technology

In the Conductivity of Fiber roll dies of prior art, there are employing electrical heating, steam heating, heat kerosene heating and electromagnetic induction heating mode. Electrical heating is low because of its temperature accuracy, so being only used for using under the at a fairly low process conditions of temperature accuracy. The heating of steam mode of heating is by its steam pressure reason, and temperature is normally no higher than 130 DEG C. It is not applied for the process condition of high-temperature. Equally, conduction oil godet equally exists roll surface maximum operation (service) temperature and is normally no higher than 200 DEG C, there is also leakage of oil, oil return line that coking effect is brought is on fire and the potential safety hazard such as blast simultaneously. Therefore this less seal wire for macromolecular material fiber of mode of heating. For meeting the Product Process demand that under existing godet high-temperature and high-temperature, thermograde difference is little. Increasing user adopts the godet of Electromagnetic Heating mode. For ensureing that product quality, particularly setting process are more and more higher to the dependence of high precision roller.

In fiber seal wire, especially staple fiber, in production line, be generally divided into two panels wire harness or three wire harness, this tow through between roll surface working area, every tow at regular intervals from, usual its spacing at 30-50mm not etc. And along with the silk speed of high-speed motion has the skew of about 10mm. Its roller is internal adopts a coil, and during heating, whole roller is heated together, and the tow of roll surface distribution is in working area non-uniform Distribution, and its heat consumes uneven, and it has the heat consumption of tow region big, it does not have tow place heat consumes little. Cause that roll surface presents temperature difference difference, in the place not having tow, namely the fore side clear area of roller, transmission side clear area, clear area between silk sheet will with the passage of production time, bigger temperature difference occurs, and drum structure has one end have end cap, its heat radiation is in asymmetric heat radiation, and transmission side heat radiation is many, and fore side heat radiation is few. The same temperature difference aggravating clear area, both sides, and temperature difference can accumulation in time, there is the change more than more than 10 DEG C, when tow edge temperature is too high, the chemical property of tow own can be destroyed, when having any different because of charging tow moisture, the temperature difference of every tow can be aggravated, cause the technological temperature generation very big difference between its product, it is understood that there may be non-defective unit mixes with defective products. Finally affect its qualification rate.

Detailed description of the invention

It is described more fully with example embodiment referring now to accompanying drawing. But, example embodiment can be implemented in a variety of forms, and is not understood as limited to embodiment set forth herein; On the contrary, it is provided that these embodiments make this utility model will fully and completely, and the design of example embodiment is conveyed to those skilled in the art all sidedly. Accompanying drawing labelling identical in the drawings represents same or similar structure, thus will omit repetition thereof.

Figure 1A and Fig. 2 A illustrates two embodiments of background technology godet. Godet 100 generally adopts the silk sheet 300 that a load coil 130 comes on pair roller barrel 110 to be heated. Godet 100 arranges groove 113 at roller wall 111 transmission side of its roller 110 can detect the temperature at roller wall 111 place for temperature probe 140, and then by controlling the heating-up temperature of device 150 (such as integrated with instrument control device) control coil 130. But the thermometric sampling that temperature probe 140 carries out is to take the air themperature in its groove 113. The accuracy of its sample temperature can be subject to environmental factors, as air flowing, ambient humidity, ambient temperature, roller rotating speed etc. affect. Accuracy can have a significant impact. Roll surface actual temperature curve is referring to Figure 1B and Fig. 2 B, and the position of temperature curve transverse axis roll surface is corresponding (position of such as corresponding silk sheet and width a, b, c), and the longitudinal axis represents measurement temperature. Wherein, 1. curve represents that godet works the temperature curve after a period of time, and 2. curve represents temperature curve when godet is just started working.

For Figure 1B, referring first to curve 2., owing to coil heats is overall heating, roll surface dispels the heat in lack of balance mode. Silk sheet operates after a period of time on roller, a local temperature for sheet contact is had to be slightly decreased (a, b region in figure), and white space radiating mode can only lean on the mode with air contact to dispel the heat between two sheets, compared with a, b region having a sheet, temperature is higher, and transmission side (this side, b tow region), dispels the heat inconsistent with fore side (side, a tow region). Fore side heat dissipation capacity is far from transmission side greatly, and work (referring to curve 1.) will cause that the roll surface temperature in territory, fore side non-material area is higher than operation lateral filament panel region for a long time. In this case, owing to the variations in temperature of roller 110 roll surface diverse location is relatively big, if the motion of silk sheet offsets, arrive the region of high-temperature, will scald with regard to tow disconnected. So can cause the technological temperature generation very big difference between its product, it is understood that there may be non-defective unit mixes with defective products. Finally affect its qualification rate.
