Abstract
The utility model relates to a random web -laying equipment field, concretely relates to random web -laying equipment fibre conveyor. The scheme is: include fan, tin forest, pipeline, pipeline vertical layout, the fan is connected at the pipeline lower extreme, last the opening of pipeline has the feed port, the tin forest is located feed port department, the pipeline inner wall is equipped with the arch. An object of the utility model is to provide an unable random web -laying equipment conveyor who adsorbs at the pipeline inner wall of fibre.
Description
Technical field
The utility model relates to random web-laying equipment field, is specifically related to a kind of random web-laying equipment fiber transporting device.
Background technology
The on-woven fiber through preliminary shredding in the effect Shi Jiangyouqian road of random web-laying equipment is to deliver to output curtain under the state forming uniform web layer, and the modular system being given rear road by output curtain makes on-woven product as nonwoven fabric.
Air lay principle: fiber through shredding, removal of impurities, mixed after feed main carding mechanism, be filament state after obtaining further combing, under the centrifugal force of cylinder high speed rotary generation and the acting in conjunction of air-flow, fiber comes off from pin cloth sawtooth, condense upon on lace curtaining (or dust cage) by pneumatic convey, form the fibre web of fibre three-dimensional disordered arrangements.
Boundary layer is the flowing thin layer that the viscous force being close to object plane during high reynolds number streams be can not ignore, also known as flow boundary layer, boundary-layer.If the fluid that viscosity is very little (as water, air etc.) is when large Reynold number and object contact have relative motion, then near the thin fluid layer of object plane because making speed reduce by viscosity shear stress; The fluid sticks being close to object plane, on object plane, equals zero with the relative velocity of object plane; By object plane upwards, the speed of each layer increases gradually, until equal with free flow velocity.L-Prandtl is called boundary layer from object plane this fluid down thin layer upwards.
But the conveying pipeline inner wall of existing random web-laying equipment is smooth, because fluid exists boundary layer, some fibre can be adjacent to and stop motion with inwall, can reduce fiber efficiency into the net like this.
Utility model content
The purpose of this utility model is the random web-laying equipment transport providing a kind of fiber cannot be adsorbed on conveying pipeline inner wall.
The utility model provides base case to be: random web-laying equipment fiber transporting device, comprises, blower fan, cylinder, conveyance conduit; Described conveyance conduit is vertically arranged, described blower fan is connected to conveyance conduit lower end; Described conveyance conduit has charging hole, and described cylinder is positioned at charging hole place; Described conveying pipeline inner wall is provided with projection.
The beneficial effect of base case is: in prior art, and conveying pipeline inner wall is smooth, and because fluid exists boundary layer, the fiber on conveying pipeline inner wall can stop motion.In this programme, be provided with projection at conveying pipeline inner wall, when fiber one end is near conveying pipeline inner wall, the other end due to the obstruction of projection cannot be close, make fiber entirety cannot press close to conveying pipeline inner wall, thus make fiber can not stop motion.Improve fiber efficiency into the net.
Scheme two: based on scheme preferred, described blower fan is air blast.Beneficial effect: the range of choice of air blast pressure is very wide, can adjust as required.
Scheme three: based on scheme preferred, described conveyance conduit lower end takes the shape of the letter U.Beneficial effect: when after closedown air blast, because the fiber in conveyance conduit runs out of steam, fall under gravity, the bottom of U-shaped pipeline can be fallen into, can continue to move to into lace curtaining place after starting air blast next time.Avoid and fall into air blast and affect air blast work.
Scheme four: based on scheme preferred, described projection is hemispherical.Beneficial effect: protruding employing is hemispherical is that what fabric integer cannot be vertical presses close to conveying pipeline inner wall because the stroke of its surperficial any two points is not vertical.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model structure random web-laying equipment fiber transporting device embodiment.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, comprise, blower fan 10, cylinder 30, conveyance conduit 20; Described conveyance conduit 20 is vertically arranged, described blower fan 10 is connected to conveyance conduit 20 lower end; Described conveyance conduit 20 has charging hole, and described cylinder 30 is positioned at charging hole place; Described conveyance conduit 20 inwall is provided with protruding 21.In addition, air blast selected by blower fan 10, and the range of choice of air blast pressure is very wide, can adjust as required.Conveyance conduit 20 bottom takes the shape of the letter U, and fiber can be avoided to fall into air blast affects air blast work.Protruding 21 is hemispherical, because the stroke of its surperficial any two points is not vertical, what fabric integer cannot be vertical presses close to conveyance conduit 20 inwall.
During work, the double action that the fiber that cylinder 30 captures blows due to centrifugal force and air-flow departs from cylinder 30.After fiber enters conveyance conduit 20, continue to move upward because air-flow blows, when one end of fiber is near conveyance conduit 20 inwall, the other end due to the obstruction of protruding 21 cannot be close, make fiber entirety cannot press close to conveyance conduit 20 inwall, thus make fiber can not stop motion.Improve fiber efficiency into the net.
