Description
Technical field
The utility model belongs to the manufacturing field of bellows, is specifically related to a kind of thermoplastic extrusion device produced for bellows.
Background technology
Bellows refers to the tubular elastomeric sensing element connected into along folding retractable direction with collapsible wrinkle sheet.Bellows is widely used in instrument and meter, and main application is the measuring cell as pressure measuring instruments, pressure is converted to displacement or power.Bellows tube wall is thinner, and sensitivity is higher, and measurement category is that tens of handkerchief is to tens of MPa.Its openend is fixed, and sealed end is in free state, and utilizes auxiliary helical spring or reed to increase elasticity.Extend along tube length direction under the effect of internal pressure during work, make movable end produce the displacement becoming certain relation with pressure.Movable end drives pointer to get final product the size of direct indicated pressure.Bellows usually combines with displacement transducer the pressure sensor forming and export as electricity, is sometimes also used as isolated component.Stretching, extension due to bellows requires larger volume change, and therefore its response speed is lower than Bourdon tube.Bellows is suitable for measuring low pressure.
Thermoplastic extruder can be used in the manufacturing of bellows, traditional thermoplastic extruder comprises following several situation: application number is: 201410307334.3 disclose a kind of thermoplastic extruder for 3d printer, comprise three-dimensional rack, described three-dimensional rack is provided with can the printing seat of three-dimensional movement, described printing seat is provided with material cylinder, described material cylinder lower end is provided with prints stub bar, discharging pressurizing piston bar is provided with in described material cylinder, described pressurizing piston bar movable upper end connects the middle part of an afterburning rocking bar, described afterburning rocking bar close end is on one side flexibly connected with between described printing seat, the close end of the another side of described afterburning rocking bar is connected with the first drive unit, described first drive unit is arranged on described printing seat.3d printer of the present invention can increase material extrusion pressure, thus ensures the quality of the profiled member such as jewellery, lamp decoration.Application number is: the 201310110666.8 thermoplastic extruders disclosing another kind of 3D printer, comprise frame, the fluid reservoir of upper end open, be located at the first resin cartridge in frame, the second resin cartridge, hoistable platform, line material extrusion device and ultraviolet spot light; The liquid ultraviolet photo-curing resin filled in first resin cartridge, the paste ultraviolet photo-curing resin filled in the second resin cartridge; Second resin cartridge bottom and line material extrusion device are connected, and line material extrusion device is provided with shower nozzle, and the irradiation position of ultraviolet spot light is positioned at below shower nozzle; Hoistable platform comprises that middle part is provided with the flat board of through hole, dull and stereotyped upper surface is provided with wire netting, is dull and stereotypedly slidably connected with two leads be located in frame; Fluid reservoir bottom is connected by the liquid reserve tank of conduit with the upper end open be located on dull and stereotyped lower surface.It is high that the present invention has printing effect; And while guarantee printing effect, can ensure that printed object density is high, non-damageable feature.Above two kinds of Patents have the advantage of himself, but still come with some shortcomings, and thermoplastic extrusion device operationally can be subject to the restriction of heater, can produce and spray uneven phenomenon, are badly in need of improving.
