The limiting block 212 can limit the downward movement of the sliding seat 210, so as to limit the downward movement of the second needle tube, thereby preventing the second needle tube from being poked to the product to be threaded. When in use, the first driving member 27 pushes the sliding seat 210 to move downwards along the guide rail, the sliding seat 210 drives the second needle tube 219 to move downwards, the touch block 211 on the sliding seat 210 touches the limiting block 212, and the first driving member 27 stops pushing the sliding seat to move downwards, so that the second needle tube can be prevented from moving downwards continuously to be poked on a product to be threaded. It can be understood that the limiting block 212 limits the maximum displacement of the sliding seat 210, and the first driving member can drive the sliding seat 210 to move to a desired position within the maximum displacement range.

The first driving member 27 may be a pneumatic cylinder structure.

A second needle cannula support 217 is mounted to the slide mount 210 at an end remote from the first drive member 27, the second needle cannula support 217 being adapted to mount a second needle cannula 219.

As shown in fig. 4, a structure of the wire cutting mechanism is given. The wire cutting mechanism 3 comprises a second drive 38, a slider 36 and a cutter portion. The slide 36 is in driving connection with a second driving member 38; one end of the cutter portion is mounted on the slider 36, and the other end extends to the bottom of the pushing portion of the threading straightening mechanism 2.

The second driving member 38 may be a pneumatic cylinder structure. Providing power to the slider.

The second driving member 38 is mounted on the driving support 39, the driving support 39 is mounted on the supporting base 310, and the supporting base 310 can be connected with the supporting frame 218.

To facilitate the sliding of the slider support, a slide mount 37 and a push rod 315 are added. The slide mount 37 is mounted to the support base 310. The push rod 315 penetrates the sliding support 37, one end of the push rod is in transmission connection with the first driving piece 27, and the other end of the push rod is connected with the sliding block 36. The push rod 315 is slidably coupled to the slide mount 37. The first driving member 27 drives the pushing rod 315, and the pushing rod 315 drives the sliding block 36 to move.

When in use, the utility model is characterized in that:

the second driving member 38 drives the slider 36 to reciprocate, and the slider 36 drives the cutter portion to rotate to cut the fuse wire 4.

As shown in fig. 4, one configuration of the cutter portion. The cutter portion includes two rotary cutters and a blade holder 34. The cutter holder 34 is provided with two rotary cutters. As can be seen in fig. 1 and 4, two rotary cutters are used. The fuse wire passes vertically through the gap between the two rotary cutters.

The tool apron 34 and the supporting plate 35 can be movably and fixedly connected through bolts 314. The support plate 35 is connected with the support riser in a mosaic.

The rotary cutter includes a cutter shaft 32, a cutter 33, a rotary joint 311, and a cam follower 312.

The slide 36 is provided with a slide slot in which the cam follower 312 is mounted. The cam follower can roll along the chute.

As shown in fig. 4, the mounting directions of the two rotary joints 311 are different, and the turning directions of the two cutter shafts 32 are also different, so that the cutters 33 on the two cutter shafts 32 turn in opposite directions to each other, thereby facilitating the cutting of the fuse wire.

The second driving member 38 drives the slider 36 to extend outwards, and one of the rotary joints 311 is pushed counterclockwise by the cam follower connected thereto, so that the cutter shaft connected to the rotary joint 311 rotates counterclockwise, and the cutter on the cutter shaft rotates counterclockwise. The other rotary joint is pushed clockwise by a cam follower connected with the rotary joint, a cutter shaft connected with the rotary joint rotates clockwise, and a cutter on the cutter shaft rotates clockwise. It can be seen that the two cutters are engaged in reverse rotation to cut the fuse wire between the two cutters.

The working modes of the utility model are as follows:

the fuse wire 4 is led out through the fuse wire reel 13 and sequentially penetrates through the porcelain eye 21, the first straightening guide wheel set 24 of the first straightening part, the second straightening guide wheel set 26 of the second straightening part, the first needle tube 213, the space between the pinch roller 216 and the rubber wheel 215 and the second needle tube 219; the fuse 4 extends outwardly through the second needle cannula 219 and is operable by threading. After threading is completed, a rotary cutter on the thread cutting mechanism cuts off the fuse wire 4. After cutting, the fuse may extend from the second needle cannula 219 by a length of 1 to 2mm.

The first straightening roller set 24 of the first straightening section and the second straightening roller set 26 of the second straightening section straighten the fuse 4 extending from the fuse reel 13, and the first needle tube 213 interacts with the second needle tube 219 to further keep the straightened fuse vertically downward.

The driving motor 28 drives the pinch roller 216 to rotate, the pinch roller 216 and the rubber roller 215 mutually squeeze the fuse wire, and the pinch roller 216 can drive the fuse wire to move downwards and simultaneously the rubber roller 215 rotates after the pinch roller 216 rotates.

In the threading working process, whether fuse wire blocking occurs or not is monitored through the second sensor, and if the fuse wire blocking occurs, the fuse wire cannot be threaded normally. Because the pushing part on the threading straightening mechanism pushes the fuse wire, when the fuse wire is blocked, the fuse wire shakes, and then touches the second sensor, an alarm is triggered, and the pushing part stops working.

The first sensor monitoring 16 also monitors whether the fuse reel 13 rotates normally, if the fuse reel 13 does not rotate, it is judged that the fuse is exhausted or the wire feeding slips, at this time, an alarm is triggered as well, and the driving motor 28 of the pushing part stops working. After a new fuse reel is replaced or overhauled, the work can be restarted.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being within the scope of the utility model, obvious variations or modifications may be made thereto.
