Description

TECHNICAL FIELD

[0001] The application relates to the technical field of yarn textile, and in particular to a cotton yarn textile yarn surface cleaning process. BACKGROUND

[0002] Yarn is a kind of textile product processed from various textile fibers to a certain fineness, and is used for weaving, rope making, thread making, knitting and embroidery, etc., and is classified into short fiber yarn and continuous filament, etc.

[0003] In the weaving process, the residual yarn in the production process is reused in the production process, and the surface of the residual yarn is covered with knots, dust, impurities and other defects in the previous use and storage process, which directly affects the stability of the subsequent weaving process. Therefore, the surface of the yarn needs to be cleaned by a yarn cleaning machine before being put into the production line again.

[0004] The existing yarn cleaning technology mainly relies on single straight-line passing through the cleaning mechanism, which leads to insufficient contact time of the yarn and easy missed detection of small points. SUMMARY

[0005] The application discloses a cotton yarn textile yarn surface cleaning process, which aims to solve the technical problems that the existing yarn cleaning technology mainly relies on single straight-line passing through the cleaning mechanism, which leads to insufficient contact time of the yarn and easy missed detection of small points.

[0006] In order to achieve the above purpose, the application adopts the following technical scheme: A cotton yarn textile yarn surface cleaning process, comprising a yarn cleaning machine, wherein the yarn cleaning machine comprises: a supporting table, the top end of which is fixedly connected with a yarn cleaning mechanism and a top suction mechanism, and the top end and the bottom end of which are simultaneously provided with a bottom supporting mechanism; a first supporting plate, which is fixedly connected to the outer walls on both sides of the supporting table; a second supporting plate, which is fixedly connected to the outer walls on both sides of the yarn cleaning mechanism, and the first supporting plate and the second supporting plate at the corresponding positions are simultaneously fixedly provided with a cross-type elevator; an electric sliding rail, which is simultaneously provided on the inner wall of the top end of the supporting table and is arranged in a staggered manner; and a coil, which is movably connected to the electric sliding rail. The yarn cleaning mechanism comprises: a roller brush one and a roller brush two, which are arranged perpendicular to each other, and the roller brush one is arranged at the two ends of the roller brush two, and the position of the roller brush one is higher than that of the roller brush two; a motor one, which is fixed to one end of one of the roller brushes one and is used for driving the roller brush one to rotate; and a motor two, which is used for driving the roller brush two to rotate. A tension monitor is fixedly installed on the supporting table and is used for monitoring the tension values of the plurality of coils, and the bottom end outer wall of each coil is fixedly connected with a sliding block, and the sliding block is movably connected to the electric sliding rail. The yarn cleaning mechanism further comprises a support frame movably connected to the top outer wall of the support table, two support plates fixedly connected to the outer wall of the support frame, and two rolling brushes simultaneously rotatably connected to the support frame; a synchronous wheel one fixedly connected to one end of the rolling brush one, and simultaneously sleeved with a synchronous belt one; The yarn cleaning mechanism further comprises two synchronous wheels fixedly connected to one end of the rolling brush two, and simultaneously staggered with a synchronous belt two; a gear two fixedly connected to one end of one of the rolling brush two; a gear one movably engaged with one side of the gear two and rotatably connected to the support frame, and the output end of the motor two is fixedly connected with the gear one.

[0007] By arranging a plurality of staggered coils, the yarn can pass through the coils to form a multi-stage loop line. At this time, the yarn cleaning mechanism contacts the surface of the yarn through the vertically arranged and continuously rotating rolling brush one and rolling brush two to clean the yarn. The rolling brush one is used for cleaning large lint impurities, and the rolling brush two is used for extruding on the yarn to clean small impurities. Thus, multi-stage cleaning, multi-directional cleaning, and long cleaning path during the yarn cleaning process are integrated, thereby effectively ensuring the cleaning effect of the yarn.

[0008] In a preferred scheme, the top adsorption mechanism comprises a negative pressure suction machine one fixedly installed on one side of the outer wall of the support frame; a conveying elbow fixedly communicated with the input end of the negative pressure suction machine one, and the output end thereof is fixedly communicated with a conveying main pipe; The top adsorption mechanism further comprises an inclined pipe fixedly communicated with the bottom inner wall of the conveying main pipe and located on one side of each rolling brush two, and the end of the inclined pipe is provided with a gap from the outer periphery of the rolling brush two; a plurality of needles movably attached to the outer wall of the rolling brush two.

[0009] By arranging the top adsorption mechanism, the impurities on the rolling brush two during rotation can be intercepted by arranging a plurality of needles. The intercepted impurities are just located in the range of the inclined pipe. At this time, based on the suction force of the negative pressure suction machine one and the conveying of the conveying main pipe and the inclined pipe, the impurities in the range of the inclined pipe can be adsorbed, thereby ensuring the continuous cleaning effect of the rolling brush two on the surface of the yarn.

[0010] In a preferred scheme, the bottom support mechanism comprises a hollow support seat fixedly connected to the top outer wall of the support table; a support frame symmetrically fixedly connected to the inner wall of the hollow support seat; a plurality of thin metal sheets equidistantly fixedly connected to the opposite inner walls of the hollow support seat, and the two support frames are located at the bottom outer wall of the plurality of thin metal sheets, and the surface of the thin metal sheet is higher than the top outer wall of the hollow support seat; The bottom support mechanism further comprises a bottom support bin fixedly connected to the bottom end outer wall of the support table, and the support table, the bottom support bin and the hollow support seat are simultaneously provided with square through slots; a negative pressure suction machine II is fixedly installed in the bottom support bin, and the input end of the negative pressure suction machine II is fixedly communicated with the square through slot.

[0011] By arranging the bottom support mechanism, the yarn height can be limited to ensure that the yarn cleaning mechanism can contact the surface of the yarn for cleaning. When the yarn is moved on the top end of the thin metal sheet, the thin metal sheet will vibrate slightly, which can make the dust on the yarn fall off and be sucked by the bottom, thereby achieving the dual effects of support and cleaning.

[0012] In a preferred scheme, the following specific steps are included: S1: threading: control the cross-type elevator to rise, leak out the coil position, and sequentially thread one end of the yarn through the coil and fix it on the winding device, and then control the cross-type elevator to descend; S2: tension adjustment: ensure that the bottom of the coil is attached to the top end of the plurality of thin metal sheets, and real-time monitor the tension by the tension monitor and adjust by the electric slide rail; S3: winding: start the winding device to move the yarn; S4: yarn cleaning: start the motor I and the motor II to drive the roller brush I and the roller brush II to clean the surface of the yarn; S5: winding end.

[0013] As can be seen from the above, a cotton yarn textile yarn surface cleaning process includes a yarn cleaning machine, which includes: a support table having a yarn cleaning mechanism and a top suction mechanism fixedly connected to the top end thereof, and a bottom support mechanism fixedly installed at the top end and the bottom end thereof; a support plate I fixedly connected to the outer walls on both sides of the support table; a support plate II fixedly connected to the outer walls on both sides of the yarn cleaning mechanism, and a cross-type elevator fixedly installed between the support plate I and the support plate II at the corresponding positions; a plurality of electric slide rails arranged in the top inner wall of the support table in a staggered manner; a plurality of coils movably connected to the electric slide rails; the yarn cleaning mechanism includes: two roller brushes I and a plurality of roller brushes II, the roller brushes I and the roller brushes II are arranged perpendicular to each other, the two roller brushes I are arranged at the two ends of the plurality of roller brushes II, and the position of the roller brush I is higher than that of the roller brush II; a motor I fixedly connected to one end of one of the roller brushes I for driving the two roller brushes I to rotate; and a motor II for driving the plurality of roller brushes II to rotate. The cotton yarn textile yarn surface cleaning process provided by the present application can realize multi-stage cleaning, multi-directional cleaning and long cleaning path during the yarn cleaning process, thereby effectively ensuring the cleaning effect of the yarn.
