Abstract

A long segment self adjusting neat device for cotton carding part has a lower pressing roller transmission mechanism which is fixed in box body(16), and an upper pressing roller(1) is fixed at right end of an upper pressing roller axis(3) by a bearing(2), while contacting a lower pressing roller(12); the utility model is characterized in that a pressing roller seat(17) is fixed at the left side of the upper pressing roller seat, the middle part of the roller seat has a spring(5), a supporting axis(15) is arranged in the right end hole of the pressing roller seat, the left side has an outside extending section, the left end lower part of which is contact with the upper part of the mandrill(18), a sensor(19) is fixed at the lower part of the mandrill, a sensor seat(21) is arranged on bottom of the box. The utility model has the advantages that: via the mechanical force arm amplified function of the pressing roller machine, the amplified time is A2 or A1, because the displacement amount of the mandrill(18) is amplified, the displacement signal of the sensor is amplified, the signal is sent back to the feeding mechanism, which makes the feeding amount adjusted at once, so as to ensure the cotton strip has the equal and neat thickness and accord with preset requirements.

Description

The long segment evereven

Technical field

The utility model belongs to textile machine, particularly parts in the carding machine.

Background technology

At present, carding machine both domestic and external is made of a plurality of parts, is provided with evereven at the rear portion of carding machine to the cotton roller place, adjusts feed quantity by signal, realizes short autoleveller, but the sliver that generates still has the gage distortion phenomenon.Recently, carding machine both domestic and external is provided with test point at the horn mouth place, and to realize the long segment autoleveller, desired processing of this test point and assembly precision are higher, and the output signal amount is little, though the irregular phenomenon of sliver thickness is made moderate progress, but still not ideal enough.For this reason, the utility model is set up one by the test point after the mechanical type amplification at the horn mouth of carding machine and the press-roller device place that leads between the cotton stalk of can coiler, thereby adjusts feed quantity, makes the sliver thickness neat and well spaced, meets the setting requirement.

Summary of the invention

The utility model is that the press-roller device between the cotton stalk of leading to carding machine horn mouth (14) and can coiler improves and forms, so it has the casing of being installed in (16) below, by motor (8), shaft coupling (7), (6), press down roll shaft (10), bearing (9), (11) and the lower compression roller transmission mechanism formed of lower compression roller (12), last pressure roller (1) is installed in the right-hand member of pressure roller shaft (3) by bearing (2), and contact with lower compression roller, roller seat (17) is equipped with in the left side that it is characterized in that pressure roller shaft, the roller seat middle part is provided with spring base, and the spring of packing into (5), spring top is equipped with pressurizing nut (4), and be screwed on the casing (16) by screw thread, fulcrum (15) is housed in the right hole of roller seat, the fulcrum two ends are contained on the casing, the roller seat left part extends left, end in contact on below, its overhanging section left side and push rod (18) head, push rod is installed in the endoporus top of sensor holder (21), spring (13) and sensor (19) are equipped with in the below of push rod, sensor holder is installed in the inner hole of casing (16), its top cylindrical is provided with locating slot, make it circumferentially fixing by screw (20), the sensor bottom is by pack into vernier knob (22) and be fixed on the bottom of casing by back-up ring of screw.The sensing mechanism that push rod (18), sensor holder (21) and sensor (19) are formed can be installed in the top of the overhanging section left end symmetrical placement in roller seat (17) left side, then contacts with push rod (18) lower head.

The utility model has the advantages that the mechanical type arm of force amplification by roller seat (17), its amplification multiple is A ₂/ A ₁, owing to the displacement of push rod (18) is exaggerated, thereby cause the displacement signal of sensor (19) to amplify, this signal feedback adjusts feed quantity to feed mechanism immediately, has guaranteed that the sliver thickness is neat and well spaced, meets the requirement of setting.

The specific embodiment

At first adjust pressurizing nut (4), make spring force give pressure roller (1) with initial pressure, next adjusts vernier knob (22), make the output signal of sensor (19) be setting value, then, with motor (8) energising work, lower compression roller (12) is rotated, drive pressure roller (1) backward rotation by friction, when sliver enters from horn mouth (14), in the time of between the lower compression roller, because the thickness of sliver self, make pressure roller (1), last pressure roller shaft (3) and roller seat (17) upwards lift direction around fulcrum (15) to be changeed, spring (5) is compressed, push rod (18) moves under the effect of spring (13) power, when meeting, the sliver thickness of input sets when requiring, then the output signal of sensor (19) is compared comparatively zero with setting value, as the thickness of sliver greater than setting value, then signal is compared with setting value greater than zero, feeds back to feed mechanism, and feed quantity is reduced, otherwise, then feed quantity increases, because the adjustment of feed quantity finally makes the sliver thickness neat and well spaced, meet the requirement of setting value, thereby realize the long segment autoleveller.Between upper and lower pressure roller during no sliver, end-of-job, motor (8) stall at this moment, under the elastic force effect of spring (5), makes roller seat, goes up pressure roller shaft, goes up pressure roller around the rotation of fulcrum downward direction, resets, and push rod resets.Motor (8) stops with full machine.
