The specific structures of the wire breaking mechanism 700 and the feeding and discharging mechanism 800 are known technologies, and they can adopt the structures disclosed in the chinese patent application No. 201921497319.4. Of course, the wire-wheel clamping jaw 802 may be replaced by a chuck, and the wire-picking and grabbing assembly 803 may also be constructed as disclosed in the chinese patent with the publication number CN 212197937U.

Further, the structure of the wire breaking mechanism 700 is slightly different from the structure of the guiding fusing device in the prior art with the application number 201921497319.4, and the difference is that: as shown in fig. 11, in this embodiment, the upper spacing wheel 701 is replaced by an upper spacing wheel 701 and the lower spacing wheel 703 is replaced by a lower spacing wheel 703, the upper spacing wheel 701 is rotatably disposed on a first cylinder 702 driving the upper spacing wheel 701 to move along a first horizontal direction Y, the lower spacing wheel 703 is rotatably disposed on a second cylinder 704 driving the lower spacing wheel 703 to move along the first horizontal direction Y, and the spacing of the wires can be achieved by using the wheel grooves of the upper spacing wheel 701 and the lower spacing wheel 703 better, so that the deflection of the wires along the first horizontal direction Y is avoided.

When the cylinder shafts of the first cylinder 702 and the second cylinder 704 extend, the wheel grooves of the upper limit wheel 701 and the lower limit wheel 703 are opposite to the wire inlet 706 between the two fuse blocks of the wire breaker 705 in the first horizontal direction Y; when the cylinder shafts of the first cylinder 702 and the second cylinder 704 are retracted, the upper limit wheel 701 and the lower limit wheel 703 are positioned at the side of the wire inlet 706 of the fuse.

As shown in fig. 11, the wire breaking mechanism 700 of the present utility model further includes a diameter measuring sensor 707 for measuring the diameter of the wire, and the wire reel can be conveniently classified by measuring the diameter of the wire, and the specific structure of the diameter measuring sensor 707 is not limited herein. The diameter measuring sensor 707 is located below or above the wire breaker, preferably, the diameter measuring sensor 707 is located below the wire breaker, so that the structure can be more compact. Above the wire breaker is arranged a wire clamping jaw 308.

Example 3

The implementation discloses a wire twisting method of the wire twisting machine, which comprises the following steps:

s1, as shown in FIG. 12, placing a full wheel b on a full wheel fixing assembly 201 and enabling a thread end to be in a position which can be clamped by a thread end fixing mechanism 300, and starting the full wheel fixing assembly 201 to fix the full wheel; the thread end fixing mechanism 300 starts to clamp the thread end of the full wheel; after manually placing the full wheel onto the full wheel securing assembly 201 and pulling the wire end between the two jaws of the wire end clamp 301, the full wheel securing assembly 201 may then be activated by manually pressing an activation button to secure the full wheel while the two jaws of the wire end clamp 301 are closed to clamp the wire end.

S2, then, the thread take-up mechanism 400 starts to enable the thread take-up lever 401 to rotate along the winding direction of the thread on the full wheel, and then continuously rotate for more than one circle after contacting with the thread between the full wheel and the thread end fixing mechanism and stop between two clamping blocks of the thread twisting component, and in the thread take-up process of the thread take-up lever, the full wheel fixing component drives the full wheel to take off thread in cooperation with the action of the thread take-up lever.

Specifically, the horizontal moving component 404 of the thread take-up mechanism 400 drives the rotating component 403 to move from the second position to the first position, then the longitudinal moving component 405 drives the thread take-up lever 401 to move downward, then the rotating driving mechanism 514 drives the thread take-up lever 401 to rotate counterclockwise, as shown in fig. 13-15, the thread take-up lever 401 contacts the first thread from the upper side of the first thread c1 between the thread end clamping component and the full wheel and drives the first thread to rotate around the full wheel for one turn until the thread take-up lever 401 is located between the two chucks, at this time, a coil c2 is formed on the thread take-up lever 401, and simultaneously the thread take-up lever 401 bends the second thread c3 between the full wheel and the thread end clamping component into a V-shaped first segment c4 and a second segment c5, and the coil, the first segment c4 and the second segment c5 are the thread taken up by the thread take-up lever. In the process of continuing revolution after the thread take-up lever 401 contacts with the thread, the full-wheel rotating mechanism 200 drives the full-wheel to rotate for paying-off, and the paying-off speed is matched with the rotating speed of the thread take-up lever 401 so as to keep the thread to be picked up in a tensioning state.

S3, the thread twisting mechanism 500 is started to enable the thread twisting clamping jaw 515 to clamp the thread lifted by the thread taking-up lever 401, and then the thread taking-up lever 401 moves upwards and is separated from the coil, the first section and the second section.

Specifically, the raising assembly 504 of the threading mechanism 500 moves the threading jaw 515 to a predetermined height, at which point the notches of the two clamping blocks of the threading jaw 515 face upward, as shown in fig. 5. As shown in fig. 15, the linear translation assembly 503 drives the thread twisting assembly 502 to move toward the thread take-up lever 401, the two clamping blocks 525 of the thread twisting clamp 515 are contacted with the first segment C4 and the second segment C5 and continue to pay out and move toward the full wheel until the clamping mouths 304 of the two clamping blocks 525 are positioned at two sides of the coil, and the thread take-up lever 401 is positioned at the C-shaped notch of the two clamping blocks 525, as shown in fig. 16. Subsequently, the jaw cylinder 524 of the threading jaw 515 drives the two clamping blocks 525 closed to clamp the first segment c4, the second segment c5 and the coil c 2. The longitudinally moving component 405 then drives the take-up lever 401 upward to disengage it from the coil, first segment and second segment.

And S4, the wire twisting mechanism 500 is started to enable the wire twisting clamping jaw 515 to rotate for a preset number of turns to screw the wire end, and specifically, the second motor of the rotary driving mechanism 514 is started to drive the wire twisting clamping jaw 515 to rotate so as to screw the first section, the second section and the coil which are grabbed by the wire twisting clamping jaw 515 into a bundle. Of course, in the twisting process, the full wheels can carry out paying-off synchronously, or can not pay-off, and meanwhile, the thread end fixing mechanism can loosen thread ends, or can not loosen thread ends.

After the twisting is completed, each mechanism is reset, and the full wheel can be taken down from the full wheel fixing mechanism through the feeding and discharging mechanism 800. The feeding and discharging mechanism 800 may install the empty reel to the winding machine and wind the thread end to the empty reel while twisting the thread.

When the twisting machine is arranged on the moving trolley 600 and the wire breaking mechanism 700 and the feeding and discharging mechanism 800 are arranged on the moving trolley 600, and when a full wheel is required to be twisted after a blank wheel on one winding machine completes winding, the moving trolley 600 moves to the winding machine, and in the step S1, the full wheel is taken off from the winding machine a by the feeding and discharging mechanism 800 and placed on the full wheel rotating assembly 403, meanwhile, a wire head of the full wheel is synchronously moved to a position which can be clamped by the wire head fixing mechanism 300 by a wire picking and grabbing assembly of the feeding and discharging mechanism 800, at this time, whether a full wheel exists on the full wheel rotating assembly 403 or not can be determined by a sensor, if the full wheel exists, the full wheel fixing assembly 201 fixes the full wheel, meanwhile, the linear moving device 302 drives the wire head clamping jaw 301 to move towards the full wheel direction until two clamping jaws of the wire head clamping jaw 301 are positioned on the upper side and the lower side of the wire head, and then, the two clamping jaws are driven to clamp the wire head pneumatically.

Of course, before the loading and unloading mechanism 800 performs the full-wheel unloading, the wire between the full-wheel and the paying-off mechanism 900 needs to be fused, and the process of driving the thread picking and grabbing assembly 803 to pick the wire between the full-wheel and the paying-off mechanism 900 to the fusing mechanism by the loading and unloading mechanism 800 is a known technology, which is not described herein.

Before the wire between its two fuse blocks is fused by the wire breaker 705, the wire clamping jaw on the wire breaker clamps the wire between its two jaws, and the take-up gripping assembly 803 grips the wire between the full wheel and the lower limit wheel 703, of course, the wire wheel clamping jaw 802 grips the full wheel when the take-up gripping assembly 803 grips the wire. Then, the wire breaker can fuse the wire between two fusing blocks, and after fusing, the feeding and discharging mechanism 800 can synchronously move the full wheel and the wire head.

The process of installing the idle wheel on the spool of the winding machine a and winding the thread end at the fusing mechanism on the idle wheel by the feeding and discharging mechanism 800 is also known and will not be described herein.

The utility model has various embodiments, and all technical schemes formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
