the second rotating rod 418 penetrates through the protective frame 401, and a fourth spur gear 417 is fixedly sleeved on the surface of one penetrating end; the fourth spur gear 417 is positioned in the transmission groove 13 and is meshed with the toothed ring 14; when the device works, when the steel bars start to be conveyed to the right end, the metal flexible shaft 31 starts to rotate under the acting force, namely the first bevel gear 402 rotates anticlockwise, the second bevel gear 403 starts to move clockwise, the third bevel gear 405 starts to move anticlockwise, the third bevel gear 405 moves anticlockwise to drive the first rotating rod 406 to rotate, namely the first straight gear 409 rotates, the second straight gear 410 starts to rotate under the action of rotating connection, the brush 412 on the inner wall of the second straight gear rotates and rubs on the outer surface of the steel bars, burrs on the outer surface of the steel bars can be preliminarily cleaned in the rotating process of the brush 412, and the burrs also have rotating force under the influence of the rotating force of the brush 412 to accelerate the burrs to be separated from the outer surface of the steel bars, the extrusion ring 413 is driven to rotate in the rotating process of the second straight gear 410, the surface waves are intermittently extruded and the air bag 414 is loosened through the wave, the air bag 414 is pressed to spray out the internal air through the nozzle 419 at the lower end to blow away the burr remaining in the brush 412, so that the burr is prevented from staying on the upper surface of the reinforcing steel bar for a long time to be scraped, and simultaneously, the second spur gear 410 rotates and simultaneously drives the third spur gear 416 to rotate, thereby driving the fourth spur gear 417 to rotate through the second rotating rod 418, and driving the fixing ring 12 to rotate through the engagement of the fourth spur gear 417 and the toothed ring 14.

The inner side of the brush 412 is attached to the outer surface of the steel bar, and the brush 412 is mainly used for cleaning burrs on the outer surface of the steel bar; when the brush 412 works, bristles in the common brush 412 are distributed densely, and burrs are difficult to clean due to layer-by-layer blocking when entering the brush 412, so that more and more burrs are left after a long time, and meanwhile, a plurality of burrs are left on the upper surface of the steel bar at the left end of the brush 412 and cannot be cleaned at the first time, so that the outer surface of the steel bar is scraped; according to the invention, the bristles are arranged in a spiral shape, and a gap is reserved in the middle, so that when the bristles 412 brush down burrs, the burrs inside the bristles are blown to the outside of the bristles 412 by blowing of the air bag 414, thereby solving the problem of residues inside the bristles 412, and meanwhile, when the bristles are brushed out by the spiral bristles 412, the bristles can give a rotating force to the burrs to spirally fall, thereby preventing the bristles from being remained on the upper surface of the reinforcing steel bar and rolling into the bristles 412 again to scrape the outer surface of the reinforcing steel bar along with the advancement of the reinforcing steel bar.

When the pneumatic conveying device works, when reinforcing steel bars are conveyed to the right end, the metal flexible shaft 31 starts to rotate under the acting force, namely the first bevel gear 402 starts to rotate anticlockwise, the second bevel gear 403 starts to move clockwise, the third bevel gear 405 starts to move anticlockwise, the third bevel gear 405 moves anticlockwise to drive the first rotating rod 406 to rotate, namely the first straight gear 409 starts to rotate, the second straight gear 410 starts to rotate under the action of rotational connection, the hairbrush 412 on the inner wall of the second straight gear 412 rotates and rubs on the outer surface of the reinforcing steel bars, the extrusion ring 413 is driven to rotate in the rotating process of the second straight gear 410, the air bag 414 is intermittently extruded and loosened through the surface wave shape design of the extrusion ring 413, the air bag 414 is extruded to spray out internal air through the spray nozzle 419 at the lower end to blow away burrs remained in the hairbrush 412 under the extrusion effect, and meanwhile, the second straight gear 410 drives the, thereby driving the fourth spur gear 417 to rotate through the second rotating rod 418, and thus driving the fixed ring 12 to rotate through the engagement of the fourth spur gear 417 with the toothed ring 14; meanwhile, the controller controls the servo motor to rotate along the moving direction of the steel bars, the turntable 11 is driven to start to do high-speed rotation motion, under the action of the rotating force of the turntable 11, the string rubber strips 15 rotate at a high speed, namely, the string rubber strips 15 are continuously attached to the lower surfaces of the steel bars, the surfaces of the steel bars are flapped and rubbed, and in the process that the string rubber strips 15 contact the surfaces of the steel bars, the burr cleaning mechanism 4 drives the fixing ring 12 to rotate through the toothed ring 14, so that the string rubber strips 15 are driven to rotate by the turntable 11 and simultaneously drive the string rubber strips 15 to rotate around the surfaces of the steel; the burrs slide into the absorbing groove 5 in the sliding process of the string rubber strip 15, the burrs are contacted with the cutting angle at the left end of the absorbing groove 5 when the string rubber strip 15 continuously slides, so that the burrs are scraped by the cutting angle and fall into the bottom of the absorbing groove 5, the burrs on the surface of the steel bar are easily adhered to the bottom of the absorbing groove 5 when being scraped, when the string rubber strip 15 is about to be separated from the lower surface of the steel bar, the bending angle of the string rubber strip 15 is larger, so that the air pressure groove 7 is bent, due to the fact that the inner walls of the upper end and the lower end of the air pressure groove 7 are thick, the air pressure groove 7 has the fixing effect of the positioning metal strip 8, the air pressure groove 7 cannot be contracted and stretched, namely the inner space is enlarged, when the string rubber strip 15 is completely separated from the lower surface of the steel bar, the string rubber strip is straightened under the elastic force, the air pressure groove 7 is instantaneously contracted, the inner space is reduced, the air pressure is enlarged and finally released outwards through, blow off the adhesion and realize cleanly at the burr of its bottom, make the reinforcing bar play flexible fixed action to it when coming out through extrusion molding machine 2 through installation metal flexible axle 31, its surface mounting's foam circle 32 can not cause the damage to the surface of reinforcing bar when playing fixed action simultaneously, at the in-process that the reinforcing bar was advanced towards the right end, foam circle 32 is turned towards the left end and is rotated, because metal flexible axle 31 rotates and installs and can ensure that metal flexible axle 31 remains convenient work at a certain fixed position all the time on fixed link 33, the reinforcing bar has been avoided taking place the vertical runout and has produced deformation.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
