Abstract
The invention provides a self-controlled speed-regulating and pressure-regulating drawing frame, which comprises a cotton storage mechanism, a feeding mechanism, a drawing mechanism, a slivering mechanism and a creeling mechanism sequentially connected, wherein the feeding mechanism comprises a creel, a yarn guide rod and a traversing device are connected successively; the drawing mechanism comprises a drawing roller, a rubber roller, a rubber ring and a collector; the slivering mechanism comprises a large pressing roller and a strip guide frame; the cotton storage mechanism comprises a negative pressure box, a cotton conveying pipe and a cotton storage box; and the negative pressure box is connected with a motor, a display and a sensor. The invention has the advantages that 1) a pressure value in the negative pressure box is displayed through a display device, when short cotton in the negative pressure box is increased, the negative pressure value deviates from the standard, and the rotating speed of the motor is regulated to increase through the sensor, so that the negative pressure is increased, and self-controlled speed regulation and pressure regulation are realized; and 2) the rotating speed of the motor is increased through the sensor, the negative pressure value in the negative pressure box is kept, the power utilization is saved, the yield is improved, the motor and other equipment are protected, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of drawing frame, specifically, relate to a kind of drawing frame of autocontrol speed and pressure-regulating, belong to the Weaving device technical field.
Background technology
Drafting is one important procedure in the spinning process, and effect is an internal structure of improving strip, thereby improves its long segment uniformity; Reduce weight unevenness simultaneously; Make the straightening of fibers in the strip parallel, reduce crotch, make fineness up to specification; Make the raw material of variety classes or different qualities evenly mixed, reach the mixing ratio of regulation.Mixing in doubling step mainly comprises: 1) drafting: with the 6-8 one thread and close, the long segment of improving sliver is irregular; 2) drawing-off: the sliver after will and closing is taken out long drawing-down, makes straightening of fibers parallel, and makes little flock be separated into fiber; 3) evenly mix: through each road drawing frame and close and drawing-off, the fiber of various different performances is fully mixed, to prevent to produce " aberration "; 4) slivering: with the sliver that drawing frame is processed, regular geosphere is placed in the sliver can.
Mixing in doubling step is accomplished through drawing frame; Drawing frame mainly comprises following mechanism: storage cotton machine structure, feed mechanism, drafter, slivering machine and creeling mechanism; Wherein the storage cotton is the slubbing operation of drawing frame, seems particularly important, and it is determining the fluency and the production efficiency of whole drawing process.Wherein, utilize negative pressure that cotton is imported cotton storage tank, but, occur the short flannel of cotton in the negative pressure box along with the increase of service time; And more and more, make defeated cotton resistance increasing, influenced production efficiency; Increase power consumption, increased production cost, the service life of also having reduced equipment simultaneously.
Summary of the invention
In order to overcome the weak point of prior art, the invention provides a kind of drawing frame of autocontrol speed and pressure-regulating.
The drawing frame of autocontrol speed and pressure-regulating of the present invention; Comprise the storage cotton machine structure, feed mechanism, drafter, slivering machine and the creeling mechanism that link to each other successively, wherein, described feed mechanism comprises creel, lever jack and the traversing gear that links to each other successively; Described drafter comprises drawing rollers, rubber roll, cushion rubber and collector; Described slivering machine comprises large pressuring roller and guide strip rack, and described storage cotton machine structure comprises negative pressure box, defeated cotton pipe and cotton storage tank, wherein; Described negative pressure box is connected with motor, display and sensor, and described display is arranged on described negative pressure box casing one side.
Described sensor is electrically connected with described motor.
The present invention has following beneficial effect:
1) show the force value in the negative pressure box through display unit, the short flannel in negative pressure box increases, and negative pressure value departs from standard, and sensor is promptly regulated and control the motor rev up, thereby increases negative pressure, realizes the autocontrol speed and pressure-regulating.
2) sensor increases motor speed, keeps the negative pressure value in the negative pressure box, and save electricity improves productive rate, and equipment such as protection motor increase service life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein, 1 is creel, and 2 is lever jack, and 3 is traversing gear, and 4 is drawing rollers; 5 is rubber roll, and 6 is collector, and 7 is large pressuring roller, and 8 is guide strip rack, and 9 is negative pressure box; 10 are defeated cotton pipe, and 11 is cotton storage tank, and 12 is motor, and 13 is display, and 14 is sensor; 15 are storage cotton machine structure, and 16 is feed mechanism, and 17 is drafter, and 18 is slivering machine, and 19 are creeling mechanism.
The specific embodiment
As shown in Figure 1; The drawing frame of autocontrol speed and pressure-regulating of the present invention; Comprise the storage cotton machine structure 15, feed mechanism 16, drafter 17, slivering machine 18 and the creeling mechanism 19 that link to each other successively, wherein, described feed mechanism comprises creel 1, lever jack 2 and the traversing gear 3 that links to each other successively; Described drafter comprises drawing rollers 4, rubber roll 5, cushion rubber and collector 6; Described slivering machine comprises large pressuring roller 8 and guide strip rack 9, and described storage cotton machine structure comprises negative pressure box 10, defeated cotton pipe 11 and cotton storage tank 12, wherein; Described negative pressure box 10 is connected with motor 13, display 14 and sensor 15, and described display 14 is arranged on described negative pressure box 10 casings one side.Described sensor 15 is electrically connected with described motor 13.
The present invention is in when work, through the negative pressure value in the instant demonstration negative pressure box 10 of display 14, when the increase of negative pressure box 10 along with service time; Short flannel increases, and it is big that resistance becomes, the negative pressure value step-down; At this moment, sensor 15 is regulated motor 13, improves rotating speed; With this negative pressure value that guarantees negative pressure box 10, make drawing frame save 1/3 electric weight approximately in the past.
Claims (2)
1. the drawing frame of an autocontrol speed and pressure-regulating is characterized in that, comprises the storage cotton machine structure, feed mechanism, drafter, slivering machine and the creeling mechanism that link to each other successively; Wherein, Described feed mechanism comprises creel, lever jack and the traversing gear that links to each other successively, and described drafter comprises drawing rollers, rubber roll, cushion rubber and collector, and described slivering machine comprises large pressuring roller and guide strip rack; Described storage cotton machine structure comprises negative pressure box, defeated cotton pipe and cotton storage tank; Wherein, described negative pressure box is connected with motor, display and sensor, and described display is arranged on described negative pressure box casing one side.
