Abstract
The utility model relates to the production of nonwoven fabric spinneret with a melt blown method, in particular to a spinneret applicable for a broad body module combination. The utility model comprises a broad body module combination, and at least two or more than two air distribution adjusting devices with even numbers, which are mounted on a relative position of both sides of the broad body module combination. The air distribution adjusting device comprises an air inlet chamber, at least one annular air channel and an air outlet channel, which is communicated with a spinneret spout. A plurality of micropores are opened between the air inlet chamber and the annular air channel, and between the annular air channel and the air outlet channel. The spinneret of the utility model is adopted to solve an uneven air flow problem on the whole width of the broad body melt blown spinneret, and to improve the performance and the quality of the finished products.
Description
Technical field
The utility model relates to meltblown and produces nonwoven fabric spinning head, especially a kind of spinning head that is applicable to the expanded letter module combinations.
Background technology
Spinning head is the vitals in the meltblown nonwoven production equipment.Usually, melt is extruded or spinning by a kind of suitable die assembly, comprises a spinning head of producing moulding material in the die assembly.The effect of spinning head is a row spray orifice of the runner of the macromolecule material under the molten condition in modular assembly being distributed to the die head word order, under pressure, melt is sprayed through this row hole, under the effect of high-temperature high-pressure air flow, form fibre bundle, on receiving system, form nonwoven cloth material at last.So the structure of spinning head and performance directly have influence on the technical merit of producing nonwoven fabric.
At present, the spinning head of existing spinning head, especially expanded letter, gas in process of production exists the uneven common problem of die head integral width overdraught amount in distributing.Since the gas flow maldistribution, thus cause the silk footpath on the product view picture width inhomogeneous, finally cause at the bottom of the qualification rate of finished product.The invention of a lot of raising equipment performances is arranged in the prior art, thereby and do not see have by adjusting the technical scheme that the gas distributing uniformity improves product quality.
Summary of the invention
It is a kind of by adjusting the uniformity of gas flow on the expanded letter module width that the purpose of this utility model is to provide, thereby can enhance product performance and the improved spinning head of quality.
The purpose of this utility model is achieved in that it comprises the expanded letter module, and two or more become the gas of even numbers to distribute adjusting device at least to be arranged on this expanded letter module both sides relative position.Described gas distributes adjusting device to comprise an inlet plenum, at least one annular gas passage and an outlet passageway that communicates with spinning head spout place, has several micropores between wherein said inlet plenum and annular gas passage, annular gas passage and the outlet passageway.Wherein, the aperture of described micropore is 4mm-12mm.The spacing of described adjacent two annular gas passage is 6mm-20mm.
Further, described gas distributes adjusting device also to comprise a gas carding apparatus that is arranged in the outlet passageway.Described gas carding apparatus is arranged on the airway of the S-type or undaform in the outlet passageway.
Described gas distributes adjusting device also to comprise an attemperating unit that is arranged on the outlet passageway outside.Described attemperating unit is the electrical heating attemperating unit.
Adopt spinning head of the present utility model, adopted gas to distribute adjusting device, solved the uneven problem of gas flow on the expanded letter meltblown spray silk die head integral width, improved end properties and quality.Because it is simple in structure, easy operating not only improved the output and the quality of finished product greatly, and manufacturing cost can not increase.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to accompanying drawing, the utility model comprises expanded letter module 1, and two or more become the gas of even numbers to distribute adjusting device 2 at least to be arranged on this expanded letter module both sides relative position.Described gas distributes adjusting device 2 to comprise an inlet plenum 21, at least one annular gas passage 22 and an outlet passageway 23 that communicates with spinning head spout place, have several micropores 24 between wherein said inlet plenum 21 and annular gas passage 22, annular gas passage 22 and the outlet passageway 23, the aperture of described micropore 24 is 4mm-12mm.Preferred scheme is that such aperture will be opened a row, and diameter get in the middle of for well.Technical scheme shown in the figure is to be provided with two gases at module both sides relative position to distribute adjusting device 2, also can be provided with four.Annular gas passage 22 wherein is two, so that gas flow is able to fully evenly.Certainly also can adopt three annular gas passage.The spacing of described adjacent two annular gas passage 22 is 6mm-20mm, the excessive or too small uniformity that can influence gas.Outlet passageway 23 is a long and narrow passage, and the one end communicates with micropore 24 on the annular gas passage 22, and the other end communicates with spinning head spout place.Further, gas carding apparatus 3 is set in outlet passageway 23, makes air-flow obtain further combing.Gas carding apparatus 3 shown in the figure is arranged on the S-type airway in the outlet passageway 23, can certainly be the airway of undaform.
In order to control the uniformity of air-flow, also comprise an attemperating unit 4 that is arranged on outlet passageway 23 outsides, attemperating unit 4 can be the electrical heating attemperating unit, also can be the control mode of other prior art.
In the work, after air-flow enters inlet plenum 21 from the shower nozzle both sides, micropore 24 by a row enters first annular gas passage 22 after with the gas combing, flow to again the row's micropore 24 be provided with below ', gas is all pressed in process of flowing, and just gas flows to the low place of pressure by the high place of pressure.Gas from the micropore 24 of first annular gas passage 22 ' flow to second annular gas passage 22 ', second annular gas passage 22 ' in obtain the effect identical with first annular gas passage 22.Arrive the gas spout place of spinning head after gas is through combing several times, gas flow reaches even, consistent on the feasible spray silk die head integral width.
For the better effects if that makes that gas distributes, the utility model also is provided with gas carding apparatus 3 in outlet passageway 23, and the attemperating unit 4 that is arranged on outlet passageway 23 outsides.Like this, behind the airway of gas, believe that gas can be more evenly, steadily through the S type.
Though above the utility model has been made detailed description, those of ordinary skill obviously can be recognized in the art, and previous embodiment only is for the present invention is described, and non-limiting the present invention.Multiple variation or modification to previous embodiment is made all should belong to protection domain of the present utility model.
