Abstract
The utility model relates to an air-actuated negative pressure end generating device of a drawing frame, which has the characteristics of simple structure and low requirement of the technique index of compressed air. So long as the atmospheric pressure of compressed air is between 0.3 to 0.6 Mpa, the need of end generating technique can be met. The air-actuated negative pressure end generating device of a drawing frame comprises a buncher, a seal element, a compressed air nozzle, a horn opening and an air jetting hole, the gap between a sealing member with a spherical surface, which is arranged at the front end of a pipe of the buncher and the horn opening is sealed. A sealing ring is installed under an installing plate of the horn opening, and the compressed air nozzle is installed on the sealing ring. The lower part of the horn opening is provided with air jetting via hole. The air-actuated negative pressure end generating device of a drawing frame is suitable for automatically end generation of cotton web drawing technology. Compared with the prior art, the utility model can greatly raise the end generating success ratio.
Description
Technical field:
The utility model relates to technical field of textile machine, the pneumatic negative pressure carded sliver of specifically a kind of drawing frame device.
Technical background:
" repiece " is one of operation indispensable in some textile technology process, and the repiece method is had nothing in common with each other.The innovation and creation of Chinese patent aspect spinning-in system are few in number, wherein: Italian Savio S.p.A, Germany Palitex Project-Company GmbH, Czech Rieter Elitex A.S, 92104418.6 of Tyke Si Qieerwei Knicks Tai Lai joint-stock company of Czech Erie and the application of Czech Rieter Elitex A.S., 95116221.7,96121172.5,02120658.9 and 03121768.0 patent of invention, disclosed respectively several spinning-in systems are in weaving, spinning, spin the spinning-in system that uses in the sth. made by twisting process, and do not see the record of the spinning-in system that is applicable to the cotton spinning drawing process.At present, employed drawing frame spinning-in system has two kinds in actual production, and a kind of is manual repiece, and another kind is the blast injection repiece.Manual repiece operation is many, the time is long, efficient is low, in the automated production process, especially seems clumsy; Though and the blast injection repiece solved manual repiece many drawbacks, reduced operation link, improved efficient, but very strict to the requirement of compressed-air actuated pressure and flow, compressed-air actuated pressure and flow slightly greatly, all can't finish the repiece action slightly for a short time.So the difficulty that equipment is adjusted in the production process is very big, and the repiece success rate is lower.
Summary of the invention:
The purpose of this utility model is exactly to solve the deficiency that exists in the aerojet spinning-in system, and a kind of compact conformation, the pneumatic negative pressure spinning-in system of drawing frame that the repiece success rate is high are provided.
The purpose of this utility model is to realize like this, the pneumatic negative pressure spinning-in system of drawing frame comprises buncher, seal, compressed-air atomizer and the horn mouth that has fumarole, boundling organ pipe (3) is contained in the below of buncher (2) central authorities, it is characterized in that: the front end of boundling organ pipe (3) is ball face sealing structure (4), horn mouth (5) is installed on the horn mouth installing plate (6), sealing ring (7) be installed in horn mouth installing plate (6) below, compressed-air atomizer (9) is installed on the sealing ring (7), the annular seal space that forms between compressed-air atomizer (9) one ends and sealing ring (7) and the horn mouth (5) communicates, another termination air supply pipe (8), horn mouth (5) bottom has more than one jet through hole (10), number 〉=2 of jet through hole (10) o'clock, the perforate exit position is evenly arranged on the aperture circumferential section of horn mouth (5) bottom, the annular seal space that forms between jet through hole (10) one ends and sealing ring (7) and the horn mouth (5) communicates, and the other end communicates with the outlet duct of horn mouth (5).
The utility model has the advantages that: simple in structure, low to the compressed air technique index request, as long as compressed air air pressure between 0.3-0.6Mpa, can both satisfy the needs of spinning-in process, compared with prior art, can increase substantially the repiece success rate.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a course of work schematic diagram of the present utility model.
The specific embodiment:
Embodiment 1:
The sealing of pneumatic negative pressure spinning-in system between assembling the time will guarantee the ball face sealing structure 4 and horn mouth 5 of boundling organ pipe 3 front ends, between sealing ring 7 and horn mouth 5 and the horn mouth installing plate 6.During spinning-in operation, roller 1 rotates slowly output web 11 (seeing accompanying drawing 1), opens compressed air air supply pipe 8 simultaneously, and compressed air is in nozzle 9 is sprayed onto the annular seal space that forms between sealing ring 7 and the horn mouth 5, pass through the jet through hole 10 of horn mouth 5 bottoms again, from the outlet duct ejection of horn mouth 5.Because this air flows, just in boundling organ pipe 3 and boundling organ pipe 3 above certain zone in form negative pressure, the web 11 of roller 1 output is inhaled in the boundling organ pipe 3 under the effect of negative pressure, and under the drive of air-flow, draw from the outlet duct of horn mouth 5 belows, finish repiece operation (seeing accompanying drawing 2).
Embodiment 2:
By adjusting the number of the jet through hole 10 in horn mouth 5 bottoms, can change in the boundling organ pipe 3 and the size of the negative pressure that forms in certain zone of the top of boundling organ pipe 3; Position of opening is evenly arranged on horn mouth 5 bottom aperture circumferential sections, can be guaranteed the even, smooth of compressed air.
Claims (3)
1, the pneumatic negative pressure spinning-in system of a kind of drawing frame, comprise buncher, seal, compressed-air atomizer and the horn mouth that has fumarole, boundling organ pipe (3) is contained in the below of buncher (2) central authorities, it is characterized in that: the front end of boundling organ pipe (3) is ball face sealing structure (4), horn mouth (5) is installed on the horn mouth installing plate (6), sealing ring (7) be installed in horn mouth installing plate (6) below, compressed-air atomizer (9) is installed on the sealing ring (7), the annular seal space that forms between compressed-air atomizer (9) one ends and sealing ring (7) and the horn mouth (5) communicates, another termination air supply pipe (8), horn mouth (5) bottom has jet through hole (10), the annular seal space that forms between jet through hole (10) one ends and sealing ring (7) and the horn mouth (5) communicates, and the other end communicates with the outlet duct of horn mouth (5).
