Reinforcing-bar binding machine
Technical field
The present invention relates to a kind of building implement, the reinforcing-bar binding machine of the long-time efficiency operation of especially a kind of energy.
Background technology
In the middle of building engineering, often need tie up with metal filament the reinforcing bar of arranged crosswise, wiretie labour intensity is big, and depend merely on manual tying up and often be difficult to increase work efficiency, but also waste great amount of manpower resource.Binding reinforcing bars tool construction in the market is comparatively complicated, and the glitch common laborer is difficult to maintenance, uses inconvenient.As Chinese patent ZL200720059148.8 disclosed reinforcing-bar binding machine in its background technology, mainly lean on the arc guiding device with metal filament coiled arc when it is tied up, thereby tie reinforcing bar.After tying reinforcing bar, device for screwing up also will be served in its right side, and metal filament is tightened.Because the turnover of device for screwing up needs the space, so this arc guiding device is open, does not surround reinforcing bar to be tied up fully, so can not guarantee that metal filament ties up reinforcing bar fully, result of use is bad.And the bundle silk dish of this reinforcing-bar binding machine is usually because the inertia rotation causes metal filament to overflow and coils phenomenon.In addition, other can not high efficiency work not with the binder complicated operation of pricking the silk dish.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, the long-time efficiency operation of a kind of energy is provided and can not produces the reinforcing-bar binding machine of metal filament spillover.
The present invention solves the technical scheme that its technical matters adopts: this reinforcing-bar binding machine, comprise the frame of being with work top, frame is provided with wire agency, winding mechanism, wire agency comprise its upper end can connect together the line sending arm, be subjected to the line arm, the line sending arm, be subjected to the line arm to lay respectively at the work top both sides, and be respectively equipped with guide rail in it, be provided with the line sending chain that is bearing fit with it in the guide rail, the head end of this line sending chain is provided with hook the end of a thread, is connected with the line sending actuating device on the line sending chain; Described winding mechanism comprises the wire spool that is coupling on work top, and a side of this wire spool is provided with can hook grab wiry on hook the end of a thread, and this grab is over against being subjected to the line arm; The opposite side of wire spool is provided with and can hooks bobbin winding head wiry on the line sending arm, and this bobbin winding head is positioned at the rear side of line sending arm; Wire spool also is provided with at the rear side of bobbin winding head and is used to cut off blade wiry; Be connected with the coiling actuating device on the wire spool.During use, the line sending arm, opened by the line arm, two reinforcing bars to be tied up placed the line sending arm, be subjected to (top of wire spool) between the line arm, then with the line sending arm, be subjected to line arm closure, the upper end of the two is linked together, the two in-to-in guide rail is communicated with.Start the machine, the hook the end of a thread on the line sending chain hooks metal bundle silk and move to the bottom that is subjected to the line arm on guide rail, and at this moment, hook the end of a thread is run into the grab on the wire spool, the last metal of hook the end of a thread is pricked silk deliver to the grab place.The line sending chain drives hook the end of a thread and comes from the grab disengaging, and the grab place is stayed in end wiry along guide rail toward rollback then.Hook the end of a thread is finally along with the line sending chain back retreats to reference position.Meanwhile, wire spool clickwise, grab drive end wiry rotation.At this moment, the bobbin winding head of wire spool opposite side hooks the metal filament at line sending arm place, and is being with this metal filament to rotate, and blade subsequently cuts off the metal filament of pulling out.Like this, the grab at wire spool two ends, bobbin winding head are held two ends wiry rotation respectively, thereby two reinforcing bars are bound.
Further, the line sending actuating device comprises motor, is fixed with worm gear in the rotating shaft of motor, is connected with worm screw on this worm gear, is fixed with the miniature gears that is used to drive the line sending chain on the worm screw.Like this, the motor-driven pinion rotation, miniature gears drives the line sending chain then and moves.
The line sending actuating device also comprises the metal filament conveying mechanism, and this metal filament conveying mechanism comprises wire feeding gear, the line ball pulley that cooperatively interacts, and wherein, wire feeding gear is fixed in the rotating shaft of motor, and the line ball pulley is provided with holddown spring; Work top is having wire hole with line sending arm intersection; Also be provided with defeated spool on the frame, the exit of this defeated spool is over against between wire feeding gear, the line ball pulley.Like this, metal filament is sent into from defeated spool, and between wire feeding gear, line ball pulley, passed, pass from wire hole again, can extend on hook the end of a thread.This metal filament conveying mechanism can guarantee that metal filament carries reposefully.
The rotating shaft that compresses pulley is fixed on the strut bar, and this strut bar is coupling on work top, and holddown spring is connected between strut bar and the work top.Like this, compressing pulley can open, and allows metal filament pass between itself and the wire feeding gear.By the effect of holddown spring, guarantee that wire feeding gear, line ball pulley compress, guarantee that line sending is smooth.
The coiling actuating device comprises motor, is fixed with ratchet in the rotating shaft of motor, and this ratchet is connected with the coiling gear, and the coiling gear is fixed in the rotating shaft of wire spool.Like this, when motor reverses, can drive the coiling gear and rotate, rotate thereby drive wire spool.And when motor just changeed, because the effect of ratchet, the coiling gear can not rotate, and is motionless thereby wire spool keeps.
Be subjected to the line arm being provided with travel switch with the grab corresponding position, work top is provided with halt switch at itself and line sending arm intersection, and travel switch, halt switch are connected with journey controller, and the trip controller is connected with motor.Like this, when hook the end of a thread was delivered to the grab place with metal filament, travel switch was just run in its lower end, made the motor counter-rotating, thereby drove the line sending chain toward swivel motion, and wire spool begins to rotate.When hook the end of a thread was got back to reference position, halt switch was just run in its lower end, and at this moment, motor stops operating, and wire spool just rotates a circle, gets back to reference position, and the work of tying up is finished.
The opening part of bobbin winding head and grab is provided with and is subjected to the ply-yarn drill spring.In a single day be subjected to the ply-yarn drill spring to be similar to the structure of spring pin, can guarantee that metal filament snaps in smoothly, and snap in, just can not come off easily.
Be connected on the frame by the line arm axle, be subjected to line arm bottom to connect a connecting rod, the other end of this connecting rod connects one handle, and Handle axis is connected on the frame.Push handle, by connecting rod, can drive and moved inward by the upper end of line arm, thereby link together, the line sending rail closure with the line sending arm.
The start button of motor is arranged on the handle.Like this, in the line sending rail closure, can press start button, easy to operate.
It is pullover to be subjected to the upper end of line arm to be provided with the socket joint that is complementary with the line sending arm.Like this, can be easily with the line sending arm, linked together by the line arm.
The effect that the present invention is useful is: of the present invention rational in infrastructure, simple and clear, can operate conveniently binding reinforcing bars automatically together, be fit to the common laborer, can also work long hours and the line phenomenon that can not occur overflowing, effectively raise work efficiency, suitable for large-scale promotion.
