Background technology
Carding machine is for processing cotton fiber and chemical fibre, belong to textile machine, its operation principle is that the fiber preceding working procedure sent here carries out shredding via the sheet cotton layer that hopper supplies and divides comb and removal of impurities, all sheet cottons in curling bulk are made to become the filament shape substantially stretched, and in the process, remove impurity and short flannel that cotton cleaning process carries over, then integrated certain specification sliver, be stored in cotton cylinder, for mixing in doubling step.
Carding machine structure is divided into preparing, main comb and slivering three parts, and preparing part comprises the parts such as licker-in, feed roll motor, feed plate, mote knife and taker-in grid; There are axial direct type groove or tooth bar in feed roll motor surface, and end is provided with pressue device.The cambered surface of feed plate front end coordinates with feed roll motor, mineralization pressure Pliers mouth, is beneficial to grip to cotton.Licker-in is the critical piece of preparing part, is hollow cylinder, and surperficial bag pad saw tooth bar, rotating speed is higher.Mote knife below licker-in and with mesh or dirt rod or the arc bottom drain of combing plate, in order to holding fiber and despumation and short flannel.
Current feed plate pressing mechanism pressue device adopts spring-weighted structure, it comprises upper bush, lower sleeve, adjusting screw(rod) and spring, upper bush is sleeved on lower sleeve, spring is set between the two, the upper end of upper bush connects adjusting screw(rod), adjusting screw(rod) is threaded with feed plate, lower sleeve and frame hinged.When carrying out regulating to cotton pressurization value, driving upper bush move on lower sleeve and then compress or pull-off spring by adjusting screw(rod), realizing the adjustment of pressurization value.Its shortcoming is: due to deformation quantity and the spring deformation power direct proportionality of spring, when sheet cotton thickens, cause pressing spring compression, plus-pressure also increases thereupon, because plus-pressure is not a constant, equal proportion accurately can not reflect the amount of swelling of cotton layer and react to the displacement transducer detected when causing sheet cotton to thicken.In addition difference between spring, it is consistent that feed plate both sides plus-pressure is difficult to adjustment, more reduces the accuracy that displacement transducer detects.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to adjust, consistent and can the feed plate of cotton carding machine pressing mechanism of accurate quantification to cotton pressurization value.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of feed plate of cotton carding machine pressing mechanism, comprise feed roll motor, feed plate, pressue device and frame, middle part and the frame of described feed plate are hinged, the front end of feed plate is provided with the arc groove coordinating mineralization pressure jaw with feed roll motor, pressue device is provided with between the rear end of feed plate and frame, its innovative point is: described pressue device comprises cylinder block, piston, piston rod and spring, described piston is built in cylinder block, the lower end of piston rod connects piston, cylinder block is stretched out in the upper end of piston rod, the inner chamber of cylinder block is divided into rod chamber and rodless cavity by described piston and piston rod, described upper cover of piston rod is equipped with spring, the upper end of spring props up the cavity upper surface of cylinder block, the lower end of spring props up piston upper surface, and the bottom of cylinder block arranges the air inlet be communicated with cylinder block rodless cavity, and the top of cylinder block arranges the atmospheric equilibrium mouth be communicated with cylinder block rod chamber, lower end and the frame of cylinder block are hinged, and upper end and the feed plate end of piston rod are hinged.
Preferably, the cylinder block air inlet of described pressue device is communicated with steam line, and on steam line, arrange definite value valve and Pressure gauge.
Preferably, described feed plate is provided with displacement transducer vertically downward, arc groove side is close to by this displacement transducer.
The utility model has the advantage of:
Adopt single air inlet cylinder as pressue device in the utility model, single air inlet cylinder is utilized to realize pressurization to drive feed plate around fulcrum as power, because cylinder carries out pressure adjustment by definite value valve and pressure-regulating valve, the quantification that can realize force value is given, it is accurate, consistent that pressure regulates, and without the need to carrying out single manual adjustment, reduce labour intensity, increase work efficiency; More importantly on the sheet cotton between be applied to feed roll motor and feed plate, pressurization value is a steady state value, accurate response feed plate can arrange displacement transducer, so that carding machine Auto-alignment machine carries out neat and well spaced auto-control.
