When the lead is sheared, the lower surface of the upper blade is contacted with the upper surface of the lower blade, and the staggered structure design of the upper blade and the lower blade not only provides a larger relative movement space for the shearing blade, but also avoids the impact problem between the upper blade and the lower blade to a greater extent, effectively protects the cutting edge and the transmission mechanism of the cutter, reduces the noise and prolongs the service life of the device; the staggered structure design of the upper blade and the lower blade can ensure that the upper blade and the lower blade obtain larger relative movement speed at the shearing moment, improve the shearing efficiency and the lead shearing rate and ensure the working efficiency of the firecracker lead inserting equipment.

The shearing system is a spatial four-bar mechanism formed by matching a plurality of middle sliding guide rods, middle guide rod connecting rods and middle pressing plates, and the quick return characteristic of the four-bar mechanism is reasonably utilized in design, so that on one hand, the relative movement speed of a cutter during working is improved, and the working efficiency of system operation is improved; on the other hand, the stability of system operation is improved, and the service life and service performance of the device are improved.

The automatic lead inserting device adopts pure mechanical parts for transmission, endows a mechanical automation function, and has the advantages of simple structure, relatively low requirements on manufacturing and assembling precision and the like. The mechanism adopts the kinematic pair connection relation mainly comprising a low pair, has higher operation stability, lower requirement on the working environment and longer service life.

The invention relates to an automatic insertion device and an insertion method thereof, wherein a lower support frame is driven by a driving mechanism to intermittently reciprocate along the vertical direction, and the automatic insertion device has three advantages that: firstly, after the lead is cut, a cutter of the cutting system is opened, the lower clamping rubber block is immediately opened, the lead falls, and meanwhile, the lower clamping rubber block moves upwards until the lower clamping rubber block passes through the movement horizontal plane of the cutting mechanism to clamp the upper lead, at the moment, the upper clamping plate is opened, meanwhile, the lower clamping rubber block pulls the lead to move downwards, and therefore, the tension force provided for cutting the lead is continuously maintained. Secondly, before the lead is cut off, the movement process in the vertical direction is completed under the continuous traction action of the lower clamping rubber block, the state that the traditional lead inserting device falls only through the gravity of the lead is changed (because the lead is a light flexible body, the gravity can not completely meet the requirement of the accuracy of inserting the lead), and the accuracy of the movement of the lead in the vertical direction is ensured. After the lead is cut off, the lead inserting can be finished under the auxiliary guide of the lower positioning piece, so that the accuracy and the effectiveness of inserting the lead into the firework barrel can be obviously improved. Thirdly, the lead finishes the shearing process under the traction action of the lower clamping rubber block, so that the controllability is very high, the uniformity of the length cut by the lead is higher, and the manufacturing quality of the firework lead part is ensured.
