The application provides a long-pending silk unwrapping wire automatic switching device includes: the steel wire loading device comprises a vertical column 1, wherein a first material tray 2 and a second material tray 3 are arranged on the vertical column 1, and the first material tray 2 and the second material tray 3 are used for loading steel wires;

the filament accumulating and withdrawing wheel 20 is arranged on one side of the upright post 1, and the filament accumulating and withdrawing wheel 20 comprises a first wheel part 21, a second wheel part 22 and a filament penetrating part 23.

When one of the first material tray 2 and the second material tray 3 is a working material tray, the other one is a standby material tray. It should be explained that the steel wires on the work material tray are in a use state, and the steel wires are dragged, continuously released from the work material tray and advanced forward, so that the steel wires on the work material tray are less and less. And the steel wire on the standby material tray is in a standby state. When the steel wires on the working material tray are completely placed, the standby material tray can replace the working material tray to place the wires.

It is easy to understand that if the automatic steel wire reel change is not performed by the automatic converting device, when the steel wire on one working material tray is used up, the equipment needs to be shut down first, a new material tray is replaced manually, the head end of the steel wire on the new material tray is connected to the tail end of the used steel wire, and then the equipment is started, so that the continuous running of the steel wire can be realized. The manual operation wastes time and labor, and can also influence the working efficiency of the equipment.

Through the long-pending silk unwrapping wire automatic switching device that this application provided, the steel wire on the work charging tray is put the back, and reserve charging tray can take over the work charging tray automatically, and from this, the steel wire can go on constantly in succession to steel wire production line continuous operation is convenient for.

It should be noted that, when the spare tray takes over the work tray and releases the steel wire, the spare tray becomes a new work tray. Similarly, when the steel wire on the working material tray is completely released, the material tray is empty, so that the material tray is not a 'working material tray', and a new standby material tray can be obtained by loading a new steel wire on the empty material tray or taking down the empty material tray and replacing the new material tray loaded with the steel wire.

For convenience of description, the steel wire on the work tray is referred to as a work steel wire, and the steel wire on the spare tray is referred to as a spare steel wire.

Specifically, the head end of the steel wire on the spare material tray is wound through the wire accumulating and withdrawing wheel 20 and connected with the tail end of the steel wire on the working material tray. So, reserve steel wire with be in work steel wire end to end, along with the work steel wire is constantly being emitted, the end of work steel wire receives the back of drawing, and reserve steel wire can be drawn thereupon.

Optionally, the tail end of the working wire is welded to the head end of the spare wire. Through two coils of welded connection steel wire, can enough guarantee the stability of steel wire end to end connection, can not influence the normal tape transport of steel wire again.

Optionally, the tray (the first tray 2 or the second tray 3) is a spool, and includes a cylindrical mounting portion and blocking portions disposed at two ends of the mounting portion. The steel wire winding is on the installation department, and the stop part can carry out spacing, avoid the steel wire to break away from the installation department from the tip to the steel wire.

When the wires are wound on the tray layer by layer, the ends of the wires are usually pressed downward, and when the wires above are not paid out, the ends of the wires are difficult to be pulled out. Therefore, in one embodiment, only the steel wires on the spare tray are wound through the wire accumulating and withdrawing wheel 20, and the head ends of the steel wires on the spare tray are connected with the tail ends of the steel wires on the working tray after being wound around the wire accumulating and withdrawing wheel 20.

In other embodiments, if the tail end of the steel wire on the work tray can be pulled out, the tail end of the steel wire on the work tray can be connected with the head end of the steel wire on the spare tray after bypassing the wire accumulating and withdrawing wheel 20. Or, after the steel wires on part of the spare material trays are wound through the wire accumulating and withdrawing wheel 20 and the steel wires on part of the working material trays are also wound through the wire accumulating and withdrawing wheel 20, the heads and the tails of the steel wires of the two material trays are connected in the wire accumulating and withdrawing wheel 20. The source of the steel wire in the accumulating and unwinding wheel 20 is not limited in this application.

Further, when the wire is wound on the wire accumulating and withdrawing wheel 20, n turns of the wire are wound on the first wheel part 21, n turns of the wire are also wound on the second wheel part 22, n is greater than 0, the wire wound on the first wheel part 21 passes through the wire penetrating part 23 and then is wound on the second wheel part 22, and the winding direction of the wire on the first wheel part 21 is opposite to the winding direction of the wire on the second wheel part 22.

In this way, in the accumulating and unwinding wheel 20, the same number of turns of the steel wire are wound on the first wheel portion 21 and the second wheel portion 22, and the end of the steel wire in the wire passing portion 23 connected to the first wheel portion 21 and the end connected to the second wheel portion 22 are located on the same side of the accumulating and unwinding wheel 20. Meanwhile, the winding directions of the steel wires on the first wheel part 21 and the second wheel part 22 are opposite, so that the steel wires in the wire penetrating part 23 are not continuously and equidirectionally wound with the steel wires in the first wheel part 21 or continuously and equidirectionally wound with the steel wires in the second wheel part 22.

Thereby, the steel wire in the wire-passing part 23 is separated from the wire-passing part 23, and the steel wire in the wire accumulating and withdrawing wheel 20 can be released. Alternatively, the wire accumulated on the wire withdrawing wheel 20 can be gradually released by moving the wire in the wire feeding portion 23 in the direction opposite to the winding direction of the wire.

In one embodiment, only the wire from the spare reel is wound around the accumulating and unwinding wheel 20. Referring to fig. 2 to 4, in this embodiment, a certain length of steel wire is paid out from a spare tray, the paid-out steel wire is wound on the first wheel 21 clockwise by n turns, the steel wire is then passed through the wire-passing portion 23, the wire is supported by the wire-passing portion 23, and then the steel wire is wound on the second wheel 22 counterclockwise by n turns. At this time, one end of the wire threading part 23, which is connected to the first wheel part 21, is used as a start end of wire winding, and the wire is seen from the first wheel part 21, and the wire wound around the first wheel part 21 is wound counterclockwise; one end of the wire threading part 23, at which the wire is connected to the second wheel part 22, is used as a starting end of wire winding and is seen from the second wheel part 22, and the wire wound around the second wheel part 22 is also wound counterclockwise. When the steel wire on the working material tray is released to the tail end of the working steel wire and is dragged, the head end of the steel wire on the standby material tray is dragged along with the steel wire.

In the first embodiment, after the head end of the spare wire is pulled, the wire on the wire-passing part 23 is separated from the wire-passing part 23, and the wire wound on the accumulating and withdrawing wheel 20 is unsupported. Thus, as the wire on the spare tray continuously advances forward, the wire on the accumulating and withdrawing wheel 20 is gradually pulled out.

In the second embodiment, after the head end of the spare wire is pulled, the wire feeding portion 23 rotates in a direction opposite to the wire winding direction, i.e., counterclockwise as shown in fig. 2 to 4, the wire feeding portion 23 can gradually release the wire on the accumulated wire unwinding wheel 20, and the released wire is gradually pulled out along with the pulling of the head end.

It can be seen that, since the number of turns of the wire on the first wheel portion 21 and the second wheel portion 22 is the same, the wire wound on the accumulated wire unwinding wheel 20 can be completely released, and no wire is left on the accumulated wire unwinding wheel 20 after the reel change is completed.

Through setting up the long-pending head end of withdrawing the wire wheel 20 winding reserve steel wire and the end of work steel wire, the reel change in-process, long-pending withdrawing the wire wheel 20 can carry out tension control to the steel wire through the marching of the head end of supporting reserve steel wire, cooperation steel wire. Especially, when the spare material tray shifts to the work station, the wire accumulating and returning wheel 20 can release the steel wire to compensate the steel wire supply fault when the spare material tray is not in place, thereby avoiding the problem that downstream equipment can not continuously pull the steel wire.

In the first embodiment, in order to facilitate the detachment of the steel wire from the wire-passing portion 23, the wire-passing portion 23 may be movable or deformable in one embodiment. Therefore, during the coil changing, the wire penetrating part 23 is moved, or the wire penetrating part 23 is deformed, so that the steel wire on the wire penetrating part 23 is separated from the wire penetrating part 23, and the steel wire on the accumulating and unwinding wheel 20 is released.

For example, referring to fig. 3, the wire feeding portion 23 is a round rod, the left end of which is connected to a driving member (e.g., an air cylinder, an electric cylinder, etc.), and the right end of which is a free end. In a normal state, the round bar is positioned above the first wheel portion 21 and the second wheel portion 22; the steel wire is wound on the first wheel part 21 clockwise by n circles, then wound on the wire threading part 23 clockwise, and finally wound on the second wheel part 22 counterclockwise by n circles. When the coil is changed, the driving member drives the wire-passing portion 23 to move from right to left, so that the steel wire on the wire-passing portion 23 is separated from the wire-passing portion 23 from the right end.

The present application does not limit the manner in which the wire is separated from the threading portion 23.

Optionally, n = 1. The number of the winding turns of the steel wires on the accumulated wire withdrawing wheel 20 is small, the control of the belt moving tension of the steel wires is facilitated, and the tension is prevented from being out of control because a large number of steel wires are not tensioned by the accumulated wire withdrawing wheel 20 any more after the steel wires are separated from the wire penetrating part 23.

Optionally, the yarn accumulating and withdrawing wheel 20 is rotatably arranged on one side of the upright post 1; when the wire on the accumulating and unwinding wheel 20 is drawn, the accumulating and unwinding wheel 20 rotates to travel around the wire provided on the accumulating and unwinding wheel 20.

In the embodiment shown in fig. 1, the filament accumulating and withdrawing wheel 20 is arranged at the top of the upright post 1 and above the first wheel part 21 and the second wheel part 22. In other embodiments, the wire accumulating and withdrawing wheel 20 may be disposed on either side surface of the upright post 1 or outside the upright post 1, or may be disposed below or on the side of the first wheel portion 21 and the second wheel portion 22, as long as the normal running of the wire is not hindered.

The accumulated wire withdrawing wheel 20 can rotate, and when the steel wires on the accumulated wire withdrawing wheel 20 are dragged, the accumulated wire withdrawing wheel 20 can reduce the friction force between the accumulated wire withdrawing wheel and the steel wires through rotation and can guide the steel wires to move forwards.

In order to avoid the accumulated wire-withdrawing wheel 20 from being excessively rotated under the influence of factors such as self inertia when being subjected to the reverse traction force of the steel wire, and further influencing the belt tension of the steel wire, optionally, the accumulated wire-withdrawing pay-off automatic switching device further comprises: the rotating shaft 4 and the wire accumulating and withdrawing wheel 20 are rotatably arranged on the rotating shaft 4; the damping elastic sheet is arranged on the rotating shaft 4, can provide friction damping for the accumulated wire withdrawing wheel 20, and is favorable for the rotation balance of the accumulated wire withdrawing wheel 20.

In another embodiment, referring to fig. 1 and 2, the volume filament withdrawing wheel 20 further comprises a connecting part 24 disposed between the first wheel part 21 and the second wheel part 22; the wire-penetrating part 23 is arranged on the connecting part 24, and an opening is arranged on the wire-penetrating part 23; when the steel wire on the wire accumulating and withdrawing wheel 20 is pulled, the wire accumulating and withdrawing wheel 20 rotates, and when the wire penetrating part 23 rotates to the opening downward, the steel wire in the wire penetrating part 23 can be separated from the wire penetrating part 23 through the opening.

In the illustrated embodiment, the steel wire on the spare tray is wound around the second wheel 22 and then connected to the end of the steel wire on the work tray. Therefore, the connecting portion 24 is preferably fixedly connected to the second wheel portion 22. When the spare wire is pulled, the second wheel part 22 rotates around the rotating shaft 4 under the reverse acting force of the wire, and drives the connecting part 24 and the wire penetrating part 23 to rotate along with the second wheel part. When the wire-passing portion 23 rotates to have the opening facing downward, the wire in the wire-passing portion 23 can be separated from the wire-passing portion 23 through the opening by the self weight of the wire and the downward traction force, and the wire on the wire accumulating and unwinding wheel 20 is released.

Alternatively, in this embodiment, the first wheel unit 21 and the second wheel unit 22 are fixedly connected, and at this time, the entire accumulated yarn unwinding wheel 20 rotates in synchronization with the traction of the leading end of the spare wire.

Alternatively, in this embodiment, the first wheel part 21 and the second wheel part 22 rotate independently, and at this time, after the head end of the spare wire is pulled, the second wheel part 22 drives the connecting part 24 and the wire threading part 23 to rotate synchronously, but does not affect the first wheel part 21, and the first wheel part 21 does not rotate independently until the wire in the wire threading part 23 is pulled to further drive the wire on the first wheel part 21 to move.

For the second embodiment, in order to facilitate the wire feeding part 23 to discharge the wire in a rotating manner, in one embodiment, the wire feeding part 23 may rotate around the first tray 2 or the second tray 3; the wire-passing part 23 rotates along the winding direction of the steel wire on the second tray 3, and the steel wire on the wire accumulating and withdrawing wheel 20 can be released.

In this embodiment, the threading part 23 may be disposed outside the first tray 2 or the second tray 3; alternatively, referring to fig. 4, in the illustrated embodiment, the accumulating and unwinding wheel 20 further includes a rotating disc 25 disposed between the first wheel portion 21 and the second wheel portion 22; the threading part 23 is provided on the turntable 25. The turntable 25 is connected to a rotary driving member (such as a rotary cylinder, a motor, etc.), and when the head end of the spare wire is pulled, the turntable 25 rotates in a direction opposite to the winding direction of the wire to drive the wire feeding portion 23 to revolve around the axis of the turntable 25, thereby gradually releasing the wire on the accumulated wire unwinding wheel 20.

In the embodiment shown in fig. 4, the spare wire is wound around the second wheel portion 22 and then connected to the end of the working wire; the spare wire is firstly wound on the first wheel part 21 clockwise, passes through the wire-passing part 23 on the turntable 25, and then is wound on the second wheel part 22 anticlockwise. When the accumulated wire withdrawing wheel 20 releases the wire, the rotating disc 25 rotates counterclockwise, the wire threading part 23 drives the steel wire therein to revolve counterclockwise around the axis of the rotating disc 25, the steel wire in the wire threading part 23 further drives the steel wire in the first wheel part 21 and the second wheel part 22 connected with the wire threading part to move counterclockwise, and finally the steel wire in the first wheel part 21 and the second wheel part 22 is separated from the corresponding wheel parts.

Further, in order to avoid the steel wire being retained in the wire passing portion 23 after the steel wire accumulated on the wire accumulating and withdrawing wheel 20 is completely released, the wire passing portion 23 may be configured to be hook-shaped, or an opening may be provided on the wire passing portion 23, so that the steel wire finally breaks away from the wire passing portion 23. Alternatively, the threading part 23 is provided as a jaw, and when the jaw is closed, a passage is provided therein, and when the wire is pulled, the wire can normally travel through the passage, and after the jaw is opened, the wire can be separated from the threading part 23. The application does not limit the specific configuration of the wire threading part 23, as long as the wire can be guided to be unreeled and finally the wire can be separated.

Alternatively, the first wheel portion 21 and/or the second wheel portion 22 may be rotatably provided on the side of the threading portion 23. The active rotation of the threading unit 23 does not interfere with the first and second wheel units 21 and 22, but when the wire is pulled by the first or second wheel unit 21 or 22, the first or second wheel unit 21 or 22 can rotate on its own axis so that the wire can travel.

It should be explained that the wire drawing speed and the wire releasing speed of the wire accumulating and withdrawing wheel 20 are influenced not only by the operation parameters of the equipment but also by various factors during the actual operation of the equipment, and therefore, the tension of the wire needs to be controlled in real time.

Optionally, the automatic accumulated wire-withdrawing and paying-off switching device further comprises: the first wire clamping mechanism 30 is used for fixing the steel wires between the standby material tray and the wire accumulating and withdrawing wheel 20; and/or the second wire clamping mechanism 40 is used for fixing the steel wires between the work material disc and the wire accumulating and withdrawing wheel 20.

In the normal in-process of unreeling at work charging tray, the end of work steel wire and the head end of reserve steel wire need be in relatively fixed state, so, can enough avoid long-pending steel wire on the wire wheel 20 of moving back to influence the normal marcing of work steel wire, can guarantee again when changing a roll, the steel wire that is not pulled out on the reserve charging tray influences the play of steel wire on long-pending wire wheel 20 of moving back.

Through setting up first thread clamping mechanism 30, can fix the one end that the steel wire in long-pending silk wheel 20 links to each other with reserve charging tray to guarantee that the steel wire on the reserve charging tray state is stable, can not cause whole dish steel wire loose because the head end is pulled out.

Specifically, after a certain length of steel wire is pulled out from the spare tray, the steel wire is wound on the first wheel portion 21, and then the steel wire between the first wheel portion 21 and the spare tray can be fixed by the first wire clamping mechanism 30, so that the situation that the steel wire in the spare tray is further pulled out or is off-line is avoided. Of course, after a certain length of steel wire is pulled out from the spare material tray, the first wire clamping mechanism 30 can fix the part between the section of steel wire and the spare material tray. Alternatively, after the spare wire is wound around the wire accumulating and withdrawing wheel 20, the first wire clamping mechanism 30 may fix the wire between the wire accumulating and withdrawing wheel 20 and the spare material tray.

Optionally, in order to avoid that the steel wires in the accumulated wire unwinding wheel 20 are dragged to drive the steel wires in the standby material tray during the coil changing process, the first wire clamping mechanism 30 clamps the steel wires and then the steel wires are completely separated from the accumulated wire unwinding wheel 20 until the coil changing process is completed, the standby material tray arrives at the station, and the first wire clamping mechanism 30 releases the steel wires again so that the standby material tray is converted into a new working material tray and starts to normally unwind the wires.

Through setting up second wire clamping mechanism 40, can fix the one end that the steel wire in long-pending silk wheel 20 links to each other with the work charging tray to guarantee the steel wire on the work charging tray stable state.

Specifically, the head end of the standby steel wire is wound through the accumulated wire returning wheel 20 and is connected with the tail end of the working steel wire, and then the steel wire between the accumulated wire returning wheel 20 and the working material disc is clamped through the second wire clamping mechanism 40, so that the influence of the working material disc on the steel wire in the accumulated wire returning wheel 20 in the wire returning process is avoided, or the wrong wire returning of the accumulated wire returning wheel 20, the influence of the normal wire returning of the working material disc or the influence of the belt tension of the steel wire is avoided.

Different from the first wire clamping mechanism 30, when the tail end of the working steel wire is or is about to be drawn, the second wire clamping mechanism 4 needs to immediately release the steel wire, so that the wire accumulating and releasing wheel 20 is matched with the wire releasing to realize the coil changing.

Alternatively, the first wire clamping mechanism 30 and/or the second wire clamping mechanism 40 may employ clamping jaws, including two clamping jaws and a clamping driving member (e.g., pneumatic claw, pneumatic cylinder, etc.), which can drive the two clamping jaws toward each other to clamp the fixed wire, or alternatively, the clamping driving member can drive the two clamping jaws away from each other to release the wire.

Optionally, the first wire clamping mechanism 30 and/or the second wire clamping mechanism 40 employ electromagnets, and when the electromagnets are powered on, the electromagnets can attract the steel wire and further fix the steel wire, and after the electromagnets are powered off, the steel wire is released.

Optionally, the first wire clamping mechanism 30 and/or the second wire clamping mechanism 40 are/is a manual clamp, and an operator acts on the manual clamp to open the manual clamp so as to put in or take out the steel wire, and after releasing the manual clamp, the manual clamp can clamp the steel wire.

The present application is not limited to a specific configuration of the first wire clamping mechanism 30 and the second wire clamping mechanism 40.

Further, the automatic accumulated wire-withdrawing and paying-off conversion device further comprises a rotary driving mechanism 10, wherein the rotary driving mechanism is used for driving the upright post 1 to rotate, so that the first material tray 2 and the second material tray 3 can reach the working station alternately.

At the moment, the material tray at the working station is the working material tray. The wire is discharged after the material tray reaches the uniform working station, so that the discharged steel wires have uniform wire traveling paths, and the normal operation of downstream equipment is further facilitated.

In the embodiment shown in fig. 1, only the first tray 2 and the second tray 3 are arranged on the upright post 1, and the two trays are arranged oppositely. When changing coils, the rotary driving mechanism 10 drives the upright post 1 to rotate 180 degrees, so that the standby material tray can reach the working station and be converted into a new working material tray. At the moment, the original working material tray rotates to the feeding and discharging station, the steel wire is wound again, or the empty material tray is replaced by a new material tray filled with the steel wire, so that the feeding and discharging station is configured with a spare material tray again. After the new working material tray finishes the wire releasing, the rotary driving mechanism 10 drives the upright post 1 to continuously rotate for 180 degrees, or the rotary driving mechanism 10 drives the upright post 1 to reversely rotate for 180 degrees, so that the stations of the two material trays can be alternated again, one material tray is positioned at the working station for wire releasing, and the other material tray is positioned at the feeding and discharging station for reconfiguring the standby material tray.

In other embodiments, three or more than three trays are arranged on the upright post 1, and a plurality of trays are arranged at equal intervals along the circumference. When three trays are arranged on the upright post 1, the rotary driving mechanism 10 drives the upright post 1 to rotate 120 degrees at a time. When four trays are arranged on the upright post 1, the rotary driving mechanism 10 drives the upright post 1 to rotate 90 degrees … … every time, and so on.

The rotary drive mechanism 10 may be a rotary drive member such as a rotary cylinder or a motor.

In one embodiment, referring to fig. 1, the rotary drive mechanism 10 includes: the base 11, the pillar 1 is set up on the base 11 rotatably; a drive cylinder 12, the drive cylinder 12 being swingably provided on the mounting bracket 13; a first connecting rod 14 connected to a piston rod of the driving cylinder 12; a second connecting rod 15 connecting the column 1 and the first connecting rod 14; wherein, base 11 and mounting bracket 13 are fixed to be set up, and first connecting rod 14 rotates with second connecting rod 15 to be connected, and when the piston rod that drives actuating cylinder 12 was linear motion, through the rotation of second connecting rod 15 and the swing of actuating cylinder 12, can realize the rotation of stand 1.

Optionally, a support rod is arranged on the base 11, and the upright post 1 is rotatably sleeved outside the support rod through a bearing; the base 11 and the mounting frame 13 are fixedly arranged on the same working platform.

It is easy to understand that the piston rod of the driving cylinder 12 can only do linear motion, but the upright post 1 does rotational motion, and the motion directions of the two are not uniform, so compensation is needed. Therefore, when the first link 14 moves linearly by rotationally connecting the first link 14 and the second link 15, the second link 15 can be supplied with a force to the left or right, and the second link 15 further applies a force to the column 1; since the column 1 can only rotate, the second link 15 will revolve around the axis of the column 1 while moving to the left or right; when the second link 15 revolves, the first link 14 is driven to rotate in the opposite direction, so that the driving cylinder 12 swings relative to the mounting frame 13. The direction difference of the linear motion and the rotary motion is compensated in two directions by the rotation of the two connecting rods 15 and the swing of the driving cylinder 12, so that the stable rotation of the upright post 1 is realized.

Optionally, in order to ensure that the material tray is accurately stopped at the working station or the feeding and discharging station, the working station and/or the feeding and discharging station is provided with a first stop dog, the stand column 1 is provided with a second stop dog, and when the stand column 1 rotates to the point where the first stop dog contacts the second stop dog, the first stop dog can prevent the second stop dog from continuing to move, so that the stand column 1 is ensured to reach the preset position.

Further, the automatic accumulated wire unwinding and paying-off conversion device provided by the application further comprises a detection mechanism 50 for detecting whether the steel wires on the accumulated wire unwinding wheel 20 are completely unwound or not so as to conveniently confirm whether the reel change is completed or not.

The detection mechanism 50 may be a photoelectric sensor. The photoelectric sensor can be arranged on a traveling path of the steel wires in the accumulated wire withdrawing wheel 20, and after the steel wires in the accumulated wire withdrawing wheel 20 are completely released, no steel wires exist on the traveling path any more, and the photoelectric sensor can detect that no steel wires exist in the accumulated wire withdrawing wheel 20. Alternatively, a photoelectric sensor may be provided in the accumulating and unwinding wheel 20 for detecting whether the accumulating and unwinding wheel 20 has a steel wire thereon.

Alternatively, the detection mechanism 50 may be a CCD camera (charge coupled device), and it is possible to directly determine whether the accumulating/unwinding wheel 20 has a steel wire by photographing.

Referring to fig. 1, a work material tray (in the illustrated embodiment, the first material tray 2 disposed on the right side is a work material tray) at a work station is used for releasing wires to the tail end of the steel wires thereon and is dragged, the second wire clamping mechanism 40 releases the steel wires between the accumulated wire withdrawing wheel 20 and the work material tray, the steel wires in the accumulated wire withdrawing wheel 20 are dragged, the accumulated wire withdrawing wheel 20 rotates to drive the wire threading part 23 to rotate, and meanwhile, the rotary driving mechanism 10 drives the upright post 1 to rotate; after the opening of the wire feeding part 23 faces downwards, the steel wire is separated from the wire feeding part 23 from the opening, the steel wire on the wire accumulating and withdrawing wheel 20 is gradually pulled out, and the wire is discharged by the wire accumulating and withdrawing wheel 20 so as to regulate and control the tension of the steel wire in the process that a standby material tray (in the embodiment shown in the figure, the second material tray 3 arranged on the left is the standby material tray) moves to a working station; when the detection mechanism 50 cannot detect the steel wire, the standby material tray reaches the working station to become a new working material tray; the first wire clamping mechanism 30 loosens the steel wire between the standby tray and the wire accumulating and withdrawing wheel 20, so that the steel wire on the standby tray is normally released. The manual adjustment accumulation withdrawing wheel 20 is reset, so that the opening of the wire penetrating part 23 faces upwards. The empty tray arrives at the loading and unloading station, and after a new spare tray is replaced, a steel wire with a certain length is pulled out and wound through the wire accumulating and withdrawing wheel 20, so that the head end of the spare steel wire is connected with the tail end of the working steel wire.

The automatic accumulated wire-withdrawing and paying-off conversion device further comprises a traction device 60, and the traction device is used for traction steel wires to advance.

Because the automatic conversion device for accumulated wire unwinding and paying-off enables the coil changing of the steel wire to be automatically carried out, the traction device 60 can continuously carry out traction work so as to facilitate continuous operation of equipment.

Specifically, after the steel wire on the work material tray is discharged, the tail end of the work steel wire is drawn by the drawing device 60 to further draw the steel wire on the accumulated wire withdrawing wheel 20, and the steel wire can stably run along with the gradual wire discharge of the accumulated wire withdrawing wheel 20 until the standby material tray moves to a work station and is converted into a new work material tray.

Wherein, draw gear 60 can adopt the clamping jaw, can grasp the steel wire of front end, and then draw the steel wire and constantly advance forward, reach the downstream processing station.

Because the quality of charging tray is great, it is difficult to make the charging tray rotatory, initiatively release the steel wire, for this reason, in an embodiment, draw gear 60 includes: a swing arm 61, wherein a guide wheel 62 is arranged on the swing arm 61, and a steel wire is wound through the guide wheel 62; the balancing weights 63 are arranged on two sides of the turntable 64 opposite to the swing arm 61; the rotary mounting base 65 is provided, and the rotary disc 64 is rotatably arranged on the rotary mounting base 65; when the steel wire advances, the swing arm 61 makes circular motion around the work material disc.

Specifically, referring to fig. 1, the swing arm 61 is provided with two guide wheels 62, the steel wire sequentially winds behind the guide wheels 62 and leads to the downstream, the guide wheels 62 can support and tension the steel wire, the unwinding stability of the steel wire is ensured, and the guide wheels 62 can also guide the traveling direction of the steel wire, so that the steel wire travels according to a preset route.

Optionally, the swing arm 61 is further provided with a guide block 66, a guide channel is arranged in the guide block 66, the steel wire passes through the guide channel and then leads to the downstream, and the guide block 66 can further adjust the running direction of the steel wire and also has the functions of smoothing and straightening.

When the steel wire was walked through swing arm 61, swing arm 61 can receive the counter-acting force of steel wire, consequently, set up balancing weight 63 relative with swing arm 61 on carousel 64, was favorable to swing arm 61's rotation and balance.

Because carousel 64 rotationally sets up on rotating mount pad 65, when the steel wire was advanced, the tension reverse action on the steel wire was in swing arm 61 for swing arm 61 has the trend of motion, and swing arm 61 drives the motion of carousel 64, and carousel 64 receives self and the restriction of being connected of rotating mount pad 65, can only be rotary motion, and simultaneously, balancing weight 63 can balance the atress of carousel 64, avoids swing arm 61 to stop all the time in the below of carousel 64.
