Description
Technical field
The present invention relates to the production equipment of non-weaving cloth, relate in particular to the structure of dust cage formula random web-laying equipment.
Background technology
Dust cage formula random web-laying equipment is the important equipment that is used for thick and heavy non-woven fibrofelt, pad production; The one-tenth net that is particularly suitable for various waste and old recovery and is difficult to or is inappropriate for the specialty fibers of combing is like cotton, fiber crops, hair on the neck, coconut palm and glass fibre, carbon fiber, basalt fibre and stainless steel fibre etc.
The basic principle structure of dust cage formula random web-laying equipment is as shown in Figure 1.Its course of work is: the fibrous raw material through shredding mixes is sent here by input curtain 1; Grip feeding through a pair of roller 2; By the meticulous tearing of cylinder 3 pin teeth of at a high speed rotation, grasp, peel off and become to be bordering on the filament shape; Under action of centrifugal force, fly away from cylinder then, and air inlet 4 places between roller 2 and water conservancy diversion roller 5, disperseed, deliver by the high velocity air of big flow; Dust cage 8 surfaces that condense upon inner chamber at last and be the cylinder structure of negative pressure form certain thickness fibrage, and this fibrage is seen off by the output curtain and supplied follow-up operation to carry out fixed processed.
Under many circumstances, need evenly mix into net with two or more different types of fiber.And different fibers is different because of its proportion, and fiber number is different, and specific area is different, and crimpness is also inequality, and after they broke away from from cylinder pin tooth, the speed that obtains was consistent, but the kinetic energy that obtains is not wait.When blended fiber is flown in the Venturi tube air channel of flaring; Air velocity is because of long-pending gradually greatly gradually slow of duct cross-section; And fiber is because inertia and to be higher than the speed flight of air-flow, therefore receive the retardance of air-flow simultaneously and slow down and discharges kinetic energy, but owing to their physics and the difference of geometrical properties; It is inconsistent that the variation of its kinetic energy discharges; So the speed of in air-flow, flying also is different, and flight path all is different, and this trends towards same sex gathering phenomenon gradually when just having caused different fibers in the air channel, to fly.And the fibrage that changes in gradient because of cohesion absorption thickness of the surface of dust cage shows negative pressure and also is corresponding distribution, thereby different types of fiber condenses upon trend the zones of different of dust cage and demonstrates tangible lamination.The property difference of blended fiber is big more, becomes the net lamination just obvious more.Become the net layering directly to influence the performance of products quality, and serious layering even feasible production are meaningless.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of prior art, provide a kind of heterogeneity fiber mixing that prevents to become net the dust cage formula random web-laying equipment of lamination to occur.
The objective of the invention is to realize like this: a kind of dust cage formula random web-laying equipment, comprise frame, connect the up-small and down-big Venturi tube of cross sectional shape in the frame; The upper end of Venturi tube is provided with cylinder and air inlet, and a side of cylinder is provided with the input curtain, between input curtain and cylinder, a pair of roller is set; A pair of roller is arranged on the top of air inlet; The lower end of said Venturi tube is provided with dust cage and cotton roller, and a side of dust cage is provided with the suction airduct, and the outlet side of dust cage is provided with the output curtain; Said dust cage random web-laying equipment also comprises anti-decker; Anti-decker comprises the power transmission shaft of horizontally set; Power transmission shaft is arranged in the Venturi tube; The periphery of the power transmission shaft in the Venturi tube connects blade, and the power transmission shaft two ends are passed through bearing and bearing block support respectively on frame, and an end of power transmission shaft connects transmission device.
Blade of the present invention is three, and three blades are distributed on the periphery of power transmission shaft.
The present invention can produce several like this effects:
1. the impeller periodic variation of this rotation the channel cross-section shape and the sectional position in air channel, and just periodic variation the speed and the flow direction of air-flow.Conversion is ceaselessly swept along the left and right sides of impeller in main flow field in the air channel.
2. triplicate blade impeller when rotation, the complicacy that all can produce alternation at surfaces externally and internally and the root area of blade and strong airflow field, this airflow field Zhou Erfu ground disturbance and impact main flow field.
3. triplicate blade impeller when being in first and second quadrants between the adjacent blades, from left to right intercept and capture the fiber that flies in the air-flow, and when third and fourth quadrant, these fibers is pulled out away from out impeller again in the process of turning clockwise.
Because several kinds of strong effects more than the triplicate blade impeller; Make the fiber of different specific weight and character in changeable airflow field with the attitude sporting flying of complicacy; And ceaselessly hand over to mix collision and remain the state that mixes each other, thereby make various fibers condense upon the surface of dust cage with evenly mixing and form thick and heavy fibrage.
Triplicate blade impeller of the present invention can solve the dust cage lapper effectively and handle the problem that the heterogeneity fiber mixing becomes the net layering; Greatly improved the raw material adaptability and the machine performance of dust cage lapper, had important Practical significance for the production of thick and heavy non-woven mat, cushion class product.
