Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

The first embodiment is as follows:

of course, for a more complete processing, the range covered by the workpiece 31 can be extended to feed rollers used in the feed unit 2 for feeding, also for the processing of the sliver and requiring cleaning operations; the opening positions of the upper air suction hopper 41 and the lower air suction hopper 42 can completely cover the part of the machine body 1 provided with the drafting unit 3, and the upper air suction hopper 41 and the lower air suction hopper 42 can collect and treat fallen flying flower dust and other impurities;

in the production and processing process, slivers in the textile raw materials enter a drawing frame for drawing treatment after being formed in a sliver-making mode, the feeding unit 2 feeds slivers in a sliver can into the machine body 1, and meanwhile, a plurality of slivers can enter in parallel; subsequently, the processing piece 31 in the drafting unit 3 performs drafting and straightening processing on the sliver, and finally, a buncher and other devices in the sliver forming unit 5 perform drawing on the parallel sliver, so that the evenness of the sliver is improved; in the existing textile technology, the leftover materials of the clothes are recycled, and after the leftover materials are loosened, the strips with different colors and different materials are mixed to obtain the strips with different colors and different material requirements, so that the color of the textile raw materials is adjusted without excessive dyeing, the clothes with ideal colors are prepared, the cost is saved, and the pollution is reduced;

in the existing production process, various impurities in the sliver are easily attached to the workpiece 31 in the processing process of the workpiece 31 in the extension unit, so that the normal operation of the workpiece 31 is affected, and therefore, in the prior art, the surface of the workpiece 31 is often directly contacted by arranging a wiping structure such as a roller wiper or a rotary fluff sleeve and the like, so as to clean the surface of the workpiece 31; however, in the actual production process, workers find that in the preparation process of the polyester part in the sliver, in order to increase the spinnability of the polyester fiber, an oiling agent with a smoothing and antistatic effect is added in the process of delivery of the polyester, and in the cotton carding stage, because the sliver of the polyester part is rubbed on a sliver coiling disc, the oiling agent in the sliver is gradually concentrated on the surface of the sliver, so that the combination of various impurities and the surface oiling agent is also caused, even hardening and caking are caused, the impurities are more tightly combined, the impurities are difficult to effectively clean only through the wiping effect, and the caking impurity blocks also influence the drawing and straightening processing of the entering sliver in the production process, and even fall off and enter the sliver to influence the quality of the sliver;

therefore, in order to effectively solve the above problems, the cleaning unit 4 is further modified, wherein the baffle plates 43 are slidably mounted at two side portions of the lower air draft scoop 42, the telescopic module 431 is mounted at the bottom of the baffle plates 43, and the telescopic module 431 here can be an electric telescopic rod or the like which can play a role of telescopic pushing; mounting grooves 432 are formed in the positions, corresponding to the tops of the baffles 43, of the two sides of the upper air suction hopper 41, so that after the telescopic module 431 is controlled by an external controller to start, the baffles 43 can be pushed to move upwards, the baffles 43 at the positions, corresponding to the tops, of the two sides of the lower air suction hopper 42 can move upwards and are combined with the mounting grooves 432 corresponding to the tops, and the area between the upper air suction hopper 41 and the lower air suction hopper 42 is in an approximately closed state; the cleaning unit 4 further comprises a hot air module 44, and the hot air module 44 comprises a hot air blower for supplying hot air to the part where the drafting unit 3 is located to clean the workpiece 31.

in the process, in the processing of the drawing processing stage, impurities such as flying flowers, short fibers, dust and the like on the slivers can be adhered to the contacted processing pieces 31; in order to avoid the influence on the processing of the slivers, the upper air suction hopper 41 and the lower air suction hopper 42 which are positioned at the upper side and the lower side can be started through external control, so that part of impurities which are easy to separate are fallen off under the adsorption action through the air suction action and are sucked into the upper air suction hopper 41 and the lower air suction hopper 42 to be processed; after working for a period of time, the impurities adhered to the workpiece 31 are accumulated to a certain degree, and then the feeding of the sliver is stopped at the processing gap, and the telescopic module 431 is started to move the baffle 43 upwards and combine with the mounting groove 432 corresponding to the top, so that the area between the upper air suction hopper 41 and the lower air suction hopper 42 is in an approximately closed state; then, the hot air module 44 is started to inject hot air into the interior, so that the temperature of the interior area is increased, the mobility of the oiling agent on the surface of the workpiece 31 is increased under the action of the temperature increase, a possibly formed agglomeration is also melted, the tightness of the combination of impurities in the agglomeration is reduced, so that under the action of air draft, the separation of the impurities is accelerated, more adhered oiling agent is also taken away, the cleaning degree of the workpiece 31 is further improved, and the processing quality of the strip is ensured;

through the action of the baffle 43, on one hand, impurities on the workpiece 31 are prevented from being scattered under the action of flowing air flow, so that the impurities are prevented from entering other tight parts of the machine body 1 to cause faults, on the other hand, the impurities possibly existing in an external area can be prevented from being sucked under the action of air draft, so that dust and impurities in the external area are lifted under the action of air flow, and the working environment of workers is influenced; in addition, the baffle 43 can be made of heat insulation material, such as high temperature resistant rubber, so as to avoid heat loss, and prevent the flowing heat from causing overhigh temperature in other areas and influencing the operation of electronic equipment at other parts;

there are many possible embodiments of the hot air module 44, for example, the hot air is directly introduced by a hot air blower connected to the outside through a pipeline, so that the embodiments that can achieve the above-described functions and be favorably applied to the drawing frame can be applied to the present application.

The second embodiment:

on the basis of the first embodiment, as shown in fig. 4 and 7 of the drawings of the specification, an embodiment of the hot air module 44 is provided herein, specifically, the hot air module 44 includes a blowing cavity 441, the blowing cavity 441 is disposed inside the baffle 43, and the inside of the blowing cavity 441 is communicated with a hot air blower installed outside the machine body 1 through a blowing duct 443; the side wall of the air supply cavity 441 close to the drafting unit 3 is uniformly provided with air supply holes 442, the air supply holes 442 are communicated with the inside of the air supply cavity 441, and therefore the workpiece 31 located in the closed area is uniformly subjected to the action of hot air through the action of the air supply cavity 441 and the air supply holes 442, and the removal efficiency of impurities on the workpiece 31 is improved.

The specific working process is as follows: on the basis of a specific working process of the embodiment, when the impurities adhered to the workpiece 31 need to be cleaned, the baffle plate 43 moves upwards to enable one surface of the baffle plate 43 close to the drafting unit 3 to face the area where the workpiece 31 is located, so that the air supply holes 442 on the baffle plate 43 also face the area where the workpiece 31 is located, the hot air blower outside the machine body 1 is started by starting the hot air module 44, hot air enters the air supply cavity 441 through the air supply pipeline 443 and flows out through the air supply holes 442 which are uniformly distributed, because the air supply holes 442 are uniformly distributed and completely cover the area where the workpiece 31 is located, the hot air can be dispersed and uniformly applied to different parts of the workpiece 31 through the action of the air supply holes 442, so that different parts on the workpiece 31 receive more uniform hot air impact action and heating action, a mixture of oil and impurities possibly existing on the surface of the workpiece 31 is melted under the heating action and separated from the workpiece 31 under the impact of air flow, and the cleaning efficiency of the workpiece 31 is further improved.

Example three:

in the practical process of the wiping and cleaning technical scheme in the prior art, it is found that impurities are adhered tightly and difficult to clean due to the action of the oil agent when the wiping piece is in contact with the surface of the workpiece 31, so that the impurities are accumulated in the gap and turned over along with the wiping action, and the surface of the workpiece 31 in contact is easily scratched; therefore, the cleaning roller 451 cleans impurities on the surface of the workpiece 31 through adhesion, and a more comprehensive cleaning effect on the surface of the workpiece 31 is realized;

the specific working process is as follows: on the basis of a specific working process of the embodiment, when impurities accumulated on the surface of the workpiece 31 need to be cleaned, the telescopic device connected with the cleaning arc plate 45 is started, so that the telescopic device drives the cleaning arc plate 45 to move towards the direction close to the workpiece 31 until the cleaning roller 451 on the cleaning arc plate 45 contacts with the surface of the workpiece 31, and the telescopic device stops moving; the cleaning roller 451 which is contacted with the workpiece 31 is driven to rotate along with the rotation of the workpiece 31 in the machining process, and along with the relative rotation between the workpiece 31 and the cleaning roller 451, the mixture of oil solution and impurities possibly existing on the surface of the workpiece 31 is adhered to the cleaning roller 451 in the contact process; then, with the rotation of the cleaning roller 451, the surface where the adhered foreign matters are located contacts with the scraping blade 452, the foreign matters are scraped by the scraping blade 452, and the process is repeated, so that the foreign matters on the surface of the workpiece 31 are effectively cleaned; and different from the prior art that the relative friction in the wiping and cleaning process may cause scratches on the surface of the workpiece 31, the contact between the workpiece 31 and the cleaning roller 451 in the application has less relative friction, thereby effectively reducing the scratches that may be caused on the surface of the workpiece 31.

Example four:

on the basis of the third embodiment, as shown in fig. 4-6 and fig. 8 of the attached drawings of the specification, the side wall of the mounting groove 432 is provided with an impurity removing groove 454, and the impurity removing groove 454 is a through groove and penetrates through the cleaning arc plate 45, so that a gap region between the workpiece 31 and the cleaning arc plate 45 can be communicated with the outside through the impurity removing groove 454; the scraping blade 452 is positioned on the side wall of the impurity removing groove 454, and the contact part between the scraping blade 452 and the cleaning roller 451 faces the impurity removing groove 454;

the specific working process is as follows: on the basis of the third specific working procedure of the embodiment, when the upper air draft scoop 41 starts to work, the impurity removing groove 454 facing the upper air draft scoop 41 is subjected to air suction, so that the air in the gap region between the workpiece 31 and the cleaning arc plate 45 is sucked in the direction of the upper air draft scoop 41 through the impurity removing groove 454; the scraping blade 452 is positioned on the side wall of the impurity removing groove 454, and in the working process of the scraping blade 452, impurities on the workpiece 31 are scraped, and under the flowing action of air in the impurity removing groove 454, the impurities further accelerate to be separated from the scraping blade 452 and are brought to the air suction hopper 41 along with the air flow to be effectively treated, so that the cleaning efficiency of the impurities on the scraping blade 452 is accelerated, and the impurities on the workpiece 31 can be effectively treated; when the lower air draft 42 starts to work, the working process and the technical effect of the matched cleaning arc plate 45 are basically the same.

Example five:

on the basis of the fourth embodiment, as shown in fig. 4-6 and 8 in the attached drawings of the specification, a first cleaning rod 455 is uniformly arranged at the end of the scraping blade 452, the end of the first cleaning rod 455 is in contact with the surface of the cleaning roller 451, and the end of the first cleaning rod 455 is bent away from the central axis of the cleaning roller 451; the uniformly arranged first cleaning rods 455 are in a comb shape, and can effectively scrape off impurities on the cleaning roller 451;

the specific working process comprises the following steps: on the basis of the specific working flow of the fourth embodiment, the surface of the cleaning roller 451 is made of an oleophilic material, such as a polypropylene fiber; therefore, the oil possibly existing on the surface of the workpiece 31 can be effectively adsorbed in the contact process of the cleaning roller 451 and the impurities on the workpiece 31 can be strongly adsorbed after the oil is adsorbed on the surface of the cleaning roller, so that the impurities on the surface of the workpiece 31 can be more effectively cleaned; the first cleaning rod 455 with the comb-tooth-shaped end part of the scraping blade 452 can effectively clean the impurities on the surface of the cleaning roller 451, and can not excessively scrape off the oil adsorbed on the surface of the cleaning roller 451, so that the oil is prevented from being adhered to the first cleaning rod 455 and not beneficial to the separation of the impurities; the part of the surface of the cleaning roller 451 that can adsorb the oil agent is periodically replaced after a period of operation, thereby ensuring its normal operation.

Example six:

Example seven:

on the basis of the fifth embodiment, as shown in fig. 4-6 and 8 in the attached drawings of the specification, a cleaning piece 458 is arranged at a position, opposite to the scraper 452, of the side wall of the impurity removing groove 454, a second cleaning rod 459 is uniformly arranged at a position, above the first cleaning rod 455, of the end of the cleaning piece 458, the second cleaning rods 459 are uniformly arranged, the second cleaning rods 459 are also in a comb-tooth shape, and the width of gaps between the second cleaning rods 459 is larger than that of the first cleaning rod 455;
