Description
Technical field
The present invention relates to electromagnetic heater, particularly, relate to a kind of godet roller adopting Electromagnetic Heating.
Background technology
In the Conductivity of Fiber roll dies of prior art, have and adopt the heating of electro heat, steam heating, heat kerosene and electromagnetic induction heating mode.Electro heat because of its temperature accuracy low, so can only be used for using under the quite low technological condition of temperature accuracy.Steam heating mode heats by its steam pressure reason, and temperature is not usually higher than 130 DEG C.The process condition of high-temperature can not be applicable to.Equally, there is roll surface maximum operation (service) temperature equally usually not higher than 200 DEG C in conduction oil godet roller, also there is leakage of oil, the potential safety hazard such as the on fire and blast of oil return line that coking effect is brought simultaneously.Therefore the less seal wire for High molecular material fiber of this type of heating.For meeting the little Product Process demand of thermal drop difference under existing godet roller high-temperature and high-temperature.Increasing user adopts the godet roller of Electromagnetic Heating mode.More and more higher for ensureing the dependence to high precision roller of product design, particularly setting process.
In fiber seal wire, especially staple fiber, is divided into two panels wire harness or three wire harness usually in manufacturing line, this tow through roll surface work area, between every sheet tow at regular intervals from, usual its spacing at 30-50mm not etc.And have the skew of about 10mm along with the silk speed of high-speed motion.Its roller inside adopts a coil, and during heating, whole roller is heated together, and the tow of roll surface distribution is in work area and non-uniform Distribution, and its heat exhaustion is uneven, and it has the heat exhaustion of tow region large, does not have the local heat exhaustion of tow little.Roll surface is caused to present heal differential difference, in the place not having tow, namely the clear area between the fore side clear area of roller, transmission side clear area, silk sheet will with the passing of production time, there is larger heal differential, and in drum structure, have one end to 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 heal differential of clear area, same aggravation both sides, and heal differential can accumulation in time, be greater than the change of more than 10 DEG C, when tow edge temperature is too high, can destroy the chemical nature of tow own, because of charging tow moisture have any different time, the heal differential of every sheet tow can be aggravated, cause the technological temperature generation very big difference between its product, non-defective unit may be there is and mix with defective products.Finally affect its qualification rate.

Detailed description of the invention
More fully example embodiment is described referring now to accompanying drawing.But example embodiment can be implemented in a variety of forms, and should not be understood to be limited to embodiment set forth herein; On the contrary, these embodiments are provided to make the present invention comprehensively with complete, and the design of example embodiment will be conveyed to those skilled in the art all sidedly.Reference numeral identical in the drawings represents same or similar structure, thus will omit the repeated description to them.
Figure 1A and Fig. 2 A illustrates two embodiments of background technology godet roller.The silk sheet 300 that godet roller 100 adopts a load coil 130 to come on pair roller barrel 110 usually heats.Godet roller 100 arranges groove 113 at roller wall 111 transmission side of its roller 110 and supplies temperature probe 140 can detect the temperature at roller wall 111 place, and then passes through the heating-up temperature of control setup 150 (such as integrated with instrument control setup) control coil 130.But the air themperature in its groove 113 is got in the thermometric sampling that temperature probe 140 carries out.The accuracy of its sample temperature can be subject to environmental factor, as impacts such as air flowing, ambient humidity, ambient temperature, roller rotating speeds.Accuracy can have a significant impact.Roll surface actual temperature curve is see Figure 1B and Fig. 2 B, and the position of temperature curve transverse axis roll surface is corresponding, and (position and width a, the b of such as corresponding silk sheet, c), the longitudinal axis represents measuring tempeature.Wherein, 1. curve represents the temperature curve after godet roller work a period of time, temperature curve when 2. curve represents that godet roller is just started working.
For Figure 1B, first see curve 2., because 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 slightly to decline (a, b region as in figure), and white space radiating mode can only lean on the mode contacted with air 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 (see curve 1.) just can cause the roll surface temperature in territory, fore side non-material area to be higher than operation lateral filament panel region for a long time.Under these circumstances, because the temperature traverse of roller 110 roll surface diverse location is comparatively large, if offset in the motion of silk sheet, arrive the region of high-temperature, will scald with regard to tow disconnected.The technological temperature generation very big difference between its product can be caused like this, non-defective unit may be there is and mix with defective products.Finally affect its qualification rate.
In order to solve the above-mentioned defect in background technology, the invention provides a kind of godet roller.Below in conjunction with four embodiments shown by Fig. 3 A to Fig. 4 B, godet roller provided by the invention is described.
First embodiment
See Fig. 3 A, Fig. 3 A, godet roller 200 is shown.Godet roller 200 comprises roller 210, axle 220, heating arrangement, temperature measuring equipment 240 and control setup 250.
