Abstract
A bedstead with a suction fan mainly comprises a bed frame, a transverse movable frame, a longitudinal movable frame, the suction fan, a movable bed, a power device and a control system. The transverse movable frame drives the movable bed to transversely move on the bed frame under the effect of the power device and the longitudinal movable frame drives the movable bed to longitudinally move on the bed frame under the effect of the power device. When moving to a position suitable for down filling, the movable bed stops moving, and a locking device arranged on the frame locks the movable bed, a down filling machine works to perform down filling on grids on the same row of a down quilt, meanwhile, the suction fan works to suck away excessive air in the down quilt, down is attached to the underneath side of the quilt, a large amount of manual operation is reduced, and down filling is rapider and better.
Description
Technical field
The present invention relates to one to realize quickly filling floss thus improving eiderdown quilt production efficiency and reduce people for eiderdown quilt
The bedstead of the band drawing fan of work cost, belongs to eiderdown quilt and fills the optimisation technique of floss.
Background technology
The structure of eiderdown quilt mainly includes two kinds at present, and a kind of is empty by sewing up the endoporus of eiderdown quilt on eiderdown quilt
Between be separated into the multiple strip grid parallel to each other running through eiderdown quilt endoporus, a kind of by sewing up eiderdown quilt
Endoporus is separated into multiple horizontal and vertical square grid, is reserved for the opening of down filling pipe turnover between square grid.Eider down
By by the separation barrier effect of grid, it is possible to prevent eider down from moving to other positions, prevent some positions from there is no eider down,
Some position eider downs are too much.Therefore, grid is split the most, and the eider down distribution of eiderdown quilt is the most uniform, uses
Comfort level the best.
The floss process of filling of eiderdown quilt, currently mainly by manually needing accordingly to fill the mutual of floss in down filling pipe insertion quilt
In the grid separated mutually, only one of which down filling pipe, need lattice one lattice to fill.When filling floss, typically from
Grid starts, until an outmost grid, to fill an other row the most again, until charging, after down filling pipe is inserted into position,
Start down-filling machine, eider down be charged into this grid, then fill next grid, after being full of, quilt is transferred subsequent processing,
By manually being clapped by quilt, extrude additional air, then fold for filling after the open seam of floss gets togather reserved between grid
Packing.During whole, in addition to filling floss and being to fill floss by down-filling machine, depend on artificial process, when filling floss,
Owing to large quantity of air can be charged into, make eiderdown quilt tympanites, cause a part of eider down can go to it under the effect of gas expansion
He goes by grid, therefore, the situation that the eider down in each grid of eiderdown quilt is uneven often occurs, needs the later stage to be manually bulldozed.
It is, thus, sought for one is less to artificial dependence, fill the equipment that floss is in hgher efficiency.
Summary of the invention
It is an object of the invention to: provide a kind of less to artificial dependence, fill the bedstead that floss is in hgher efficiency.
The technical scheme is that the bedstead of a kind of band drawing fan, mainly include a frame 1, transverse shifting frame 2,
