Abstract
The utility model discloses an upper air duct of a lapping machine. A pressing plate strip corresponding to an upper air duct side plate and connected to a fastening piece is arranged on the lower part of the edge of the upper end of the upper air duct side plate of the existing lapping machine, and the upper air duct side plate points towards a pre-pressing roller; a fiber hair felt strip is sandwiched between the edge of the upper end of the side plate and the pressing plate strip; the external extension part of the hair felt strip protruding out of the pressing plate strip is jointed to a lower pre-pressing roller. Therefore, the angle of the upper air duct side plate is changed, the space of the upper air duct is enlarged, the air suction flow before entering into the pre-pressing rollers is developed from nothing, the phenomena of web-turning and pleating of the surface of the web curtain are reduced or avoided, the energy is saved, and the cost is reduced; the upper air duct of the lapping machine is conductive to reconstruction of the prior art.
Description
Technical field
The utility model relates to the lapping machine in a kind of chemical fibre Spunlaid Nonwoven Line.
Background technology
Lapping machine is the visual plant of chemical fibre Spunlaid Nonwoven Line, especially pass through high speed drawing-off, the fiber of pendulum wire sub-wire becomes net through lapping machine, along lapping machine lace curtaining and under the traction of pony press, to next process, carry, the static that need to overcome fiber under high-speed friction and produce, reduce or avoid course of conveying to produce and turn over net, the phenomenon such as folded, for fibre web is entirely attached on lace curtaining, must under lapping machine lace curtaining, air channel be set, attraction through induced-draught fan penetrates (vertically) in lace curtaining suction upper air duct by the wind of lace curtaining periphery, lower air duct, return air ditch is to fan house, draining into workshop recycles again.Existing upper air duct has two closure plates, and it is the flat board being parallel to each other, and this rectangular top, flat board bottom is the inverted trapezoidal that two waists do not wait.Two closure plates are connected by side plate, and the side plate corresponding with closure plate bottom is vertical plate, and the side plate corresponding with closure plate top is swash plate, and it is straight tube below that above-mentioned closure plate and side plate form, be the upper air duct of shape tube above.Two of this upper air ducts are located in the lapping machine framework being comprised of channel-section steel, square steel and I-steel side by side.The straight tube place of being in the wind establishes the porous plate of level, and it is placed in shelf with on angle steel, and these shelf are connected with wind path wall with angle steel.Its weak point is: upper air duct side plate upper end and lace curtaining framework overlap joint, there is no ventilation gap, and be zone of silence before causing lace curtaining to enter pony press, cause lace curtaining surface to turn over net and folded.
Summary of the invention
Order of the present utility model is being that providing one can solve lace curtaining surface turns over net and folded, makes the lapping machine upper air duct of the smooth conveying of fibre web.The utility model is mainly to increase by a fiber hair felt rug at the upper air duct side plate upper end-face edge place towards pony press, and it directly rides over lower pony press surface.
Upper air duct of the present utility model has two closure plates, and it is the flat board being parallel to each other, and this rectangular top, flat board bottom is the inverted trapezoidal that two waists do not wait.Two closure plates are connected by side plate, and the side plate corresponding with closure plate bottom is vertical shape, and the side plate corresponding with closure plate top is skewed, and it is straight tube below that above-mentioned closure plate and side plate form, be the upper air duct of shape tube above.This upper air duct is two, is located at side by side in the lapping machine framework being comprised of channel-section steel, square steel and I-steel.The straight tube place of being in the wind establishes the porous plate of level, and it is placed in shelf with on angle steel, and these shelf are connected with wind path wall with angle steel.The above-mentioned upper air duct side plate upper end-face edge bottom towards pony press is provided with pressing article corresponding with it and that be connected by securing member, in the middle of side plate upper end-face edge and pressing article, accompany a fiber hair felt rug, the epitaxial part that this felt bar exceeds pressing article rides on the lower pony press in two pony presses, so just, changed the angle of upper air duct side plate, expanded upper air duct space, before making lace curtaining enter pony press, air draught flow grows out of nothing, and this connected mode can seal again simultaneously.
The utility model compared with prior art tool has the following advantages:
1, the utility model has changed the connected mode of upper air duct side end, makes lapping machine lace curtaining surface wind speed even, and net is turned on lace curtaining surface and folded phenomenon takes a turn for the better.
2, save the energy, reduce costs.
3, simple in structure, be conducive to the transformation to prior art.
accompanying drawing explanation
Fig. 1 is that the utility model is used state master to look schematic diagram.
Fig. 2 is the local enlarged diagram of Fig. 1.
In figure: 1, upper air duct I, 2, upper air duct II, 2-1 side plate, 2-2 closure plate, 2-3 porous plate, 2-4 shelf angle steel, 2-5 vertical plate, 2-6 air channel trip bolt, 2-7 sealing strip, 2-8 pressing article, 2-9 felt bar, 3, support channel-section steel, 4, square steel, 5, channel-section steel, 6, rubber blanket, 7, pony press.
the specific embodiment?
?at the lapping machine upper air duct shown in Fig. 1 and Fig. 2, use in view, upper air duct has two closure plates, and it is the flat board being parallel to each other, and this rectangular top, flat board bottom is the inverted trapezoidal that two waists do not wait.Two closure plates are connected by side plate, and the side plate corresponding with closure plate bottom is vertical shape, and the side plate corresponding with closure plate top is skewed, and it is straight tube below that above-mentioned closure plate and side plate form, be the upper air duct of shape tube above.This upper air duct is two, is located at side by side in the lapping machine framework being comprised of channel-section steel, square steel and I-steel, and between two upper air ducts, rubber blanket is established in connection place, and fastening with tapping screw.Lapping machine framework is located on lower air duct casing.Be in the wind every closure plate, side plate and lapping machine framework connection place all adds sealing strip, then uses screw fastening.The straight tube place of being in the wind establishes the porous plate of level, and it is placed in shelf with on angle steel, and these shelf are connected with wind path wall with angle steel.The above-mentioned upper air duct side plate upper end-face edge bottom towards pony press is provided with pressing article corresponding with it and that be connected by bolt, in the middle of side plate upper end-face edge and pressing article, accompany a fiber hair felt rug, the epitaxial part that this felt bar exceeds pressing article rides on the lower pony press in two pony presses.
