[0019] Preferably, a round rod is fixedly connected in the adjustment groove, and the round rod is slidably connected to the two adjustment blocks.
[0020] The effects achieved by the above components are: the two adjustment blocks slide on the upper limit of the round rod, which can make the adjustment process of the transmission roller more stable, and the round rod and the second motor do not contact each other.
[0021] Compared with the prior art, the advantages and positive effects of the utility model are that, in the utility model, by setting the installation structure, if multiple coils of wire are to be cut off at the same time, it is only necessary to clamp multiple winding drums on the rotating shaft, and slide the slide rod so that the slide rod is clamped into the corresponding slot, and the winding drum is limited. The two magnetic blocks are attracted together under the action of magnetic force, which can make the connection between the slide rod and the slot more stable. When the slide rod is clamped into the slot, the spring is in a stretched state, so the rebound elastic force of the spring acts on the slide rod, which can further enhance the stability of the connection, and slide the slide rod so that the slide rod is away from the rotating shaft. The shaft is convenient for installing the winding drum. After the winding drum is installed, the sliding rod is slid to make the rotating block fit into the rectangular groove, which can make the rotation of the rotating shaft more stable.

The two adjusting blocks 5 and the two sliders can be sliding. 93 is used to adjust the distance between the two transmission rollers 6 so as to adapt to packaging wires of different sizes. Since the slider 93 slides in the slide groove 92, rotating the crank 95 can drive the bidirectional screw 94 to rotate, thereby driving the two sliders 93 to slide. Since the two sections of the thread on the bidirectional screw 94 are in opposite directions, rotating the bidirectional screw 94 can drive the two sliders 93 to move closer to or away from each other, making the operation more convenient.
