Abstract

The invention provides a nonwoven forming press roller, which comprises a roller and a roller shaft, wherein the roller shaft penetrates through the axle center of the roller to form pivot lugs at two ends of the roller. A small roller is coaxially arranged in the roller, and spiral electric heating pipes and temperature sensors are evenly distributed on the small roller and electrically connected with a temperature controller arranged on the outer portion of the roller. Heat-conducting oil is filled in a space between the small roller and the roller and evenly heated through the electric heating pipes evenly distributed on the small roller, additional pipelines and oil supply pumps are not needed, production cost is reduced, and nonexistence of oil supply pipelines enables heat dissipation to be reduced simultaneously.

Description

The on-woven forming press-roller

Affiliated technical field

The present invention relates to tight Weaving device field, especially, is a kind of on-woven forming press-roller.

Background technology

Nonwoven fabric is a kind of non-weaving cloth, and it is directly to utilize high polymer section, staple fibre or long filament that fiber is become net through air-flow or machinery, then through the water thorn; Acupuncture, thermoforming is reinforced, the cloth of the nothing braiding that the arrangement later of last warp forms; Non-woven fabrics fiber intensity after thermoforming is reinforced improves, and retractility reduces, and makes nonwoven fabric have good DIMENSIONAL STABILITY; If do not carry out the thermoforming reinforcing or the thermoforming effect is bad, can have a strong impact on the quality of nonwoven fabric.

Granted publication CN 101581020A discloses a kind of heating roller of papermaking felt setting machine; The heated oils loop mechanism that employing goes with each other all the time; Though better solved the even problem of heat of heating roller, its inner and outside pipeline is complicated, production cost is high; Simultaneously, its outside oil feed line causes heat leakage bigger.

Granted publication CN101250795A discloses a kind of non-woven feather, hemp felt forming mechanism; Its same oil that adopts is as heat-conducting medium heating roller, and its internal structure and exterior line equipment all can the labor production costs, simultaneously; Outside oil feed line causes heat leakage bigger, and operating cost is high.

Summary of the invention

In order to address the above problem, the object of the present invention is to provide a kind of on-woven forming press-roller, this on-woven forming press-roller tool cost is low, and heating is even, the characteristics that heat leakage is little.

The technical solution adopted for the present invention to solve the technical problems is: this on-woven forming press-roller comprises roller and roll shaft; Said roll shaft passes the roller axle center and forms the pivot ear at the roller two ends; The inner coaxial small roller that is provided with of said roller; Be evenly equipped with electrothermal tube and temperature inductor on the said small roller, said electrothermal tube and temperature inductor and be arranged on the outside temperature controller of roller and be electrically connected are filled with conduction oil in the space between said small roller and the said roller.

As preferably, the electrothermal tube on the said doffer is a helical form.

As preferably, during said on-woven forming press-roller horizontal, said conduction oil pasta had not just had said small roller fully.

As preferably; The electric connecting mode of said electrothermal tube and temperature inductor and said temperature controller is: the electrical connection terminal of said heat pipe and temperature inductor is arranged on the circle of four on said roller one side pivot ear slip ring, and said slip ring cooperates with four brushes four road circuit are led to temperature controller.

The invention has the advantages that: the conduction oil in the space in this on-woven forming press-roller between small roller and the said roller does not flow out roller; Electrothermal tube by being distributed on the small roller evenly heats conduction oil; Need not other pipeline and oil feed pump, reduced production cost, simultaneously; The existence of no oil feed line has reduced heat leakage.

Description of drawings

Fig. 1 is the structural representation of this on-woven forming press-roller.

Fig. 2 is the electrical structure sketch map of Fig. 1 embodiment.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

Shown in Figure 1 is the planform sketch map of an embodiment of this on-woven forming press-roller; Shown in Figure 2 is the electrical structure sketch map of an embodiment of this on-woven forming press-roller; For the ease of saying something, Fig. 1, Fig. 2 are set forth the present invention as same embodiment at present.

In the present embodiment; This on-woven forming press-roller comprises roller 1 and roll shaft 4; Said roll shaft 4 passes roller 1 axle center and forms pivot ear 41 at roller 1 two ends, and the said roller 1 inner coaxial small roller 2 that is provided with is evenly equipped with electrothermal tube 31 and temperature inductor 32 on the said small roller 2; Said electrothermal tube 31 and temperature inductor 32 are electrically connected with being arranged on roller 1 outside temperature controller 3, are filled with conduction oil in the space between said small roller 2 and the said roller 1.

Above-mentioned on-woven forming press-roller, the electrothermal tube 31 on the said doffer 2 is a helical form.

When above-mentioned on-woven forming press-roller, said on-woven forming press-roller horizontal, said conduction oil pasta had not just had said small roller 2 fully; Because the effect of gravity; When roller 1 rotated, its inner conduction oil kept original position, and conduction oil moves with electrothermal tube 31 and contacts; Make the conduction oil more uniform temperature, thereby make roller 1 surface temperature more even.

Above-mentioned on-woven forming press-roller; Said electrothermal tube 31 and temperature inductor 32 with the electric connecting mode of said temperature controller 3 are: the electrical connection terminal of said electrothermal tube 31 and temperature inductor 32 is arranged on the circle of four on the said roller 1 one side pivot ears 41 slip ring 33, and said slip ring 33 cooperates with four brushes four road circuit are led to temperature controller 3.

When above-mentioned on-woven forming press-roller was worked, roller 1 rotated, and its inner conduction oil keeps original position, and conduction oil moves with electrothermal tube 31 and contacts; Electrothermal tube 31 by being distributed on the small roller 2 evenly heats conduction oil, after conduction oil reaches predetermined temperature, and the power supply that temperature controller 3 breaks off electrothermal tubes 31, conduction oil conducts to heat on roller 1 wall; Roller 1 carries out operations for forming, and when the conduction oil temperature descended, temperature controller 3 connected the power supply of electrothermal tube 31; Because the conduction oil in the roller 1 is heated by inside, need not other pipeline and oil feed pump, has reduced production cost; Simultaneously, the existence of no oil feed line has reduced heat leakage.

The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
