Description

TECHNICAL FIELD

[0001] The present application relates to the field of firework production, in particular to a firework and a medicine machine capable of ensuring the uniformity of particles. BACKGROUND

[0002] Nowadays, the mixing of medicines in the firework industry is mostly done manually, which is not only low in efficiency but also difficult to guarantee the quality of products, and more importantly, it is relatively dangerous. In recent years, some medicine mixing machines have appeared, but there are still many problems. For example, when the medicines are crushed, the forces acting on the medicines are inconsistent, resulting in some large particles and some small particles. Another major problem is that the uniformity of the mixed medicines is poor, and it is impossible to mix the medicines uniformly when the content of the medicines is small, which greatly affects the quality of products and even causes safety accidents.

[0003] Chinese patent CN108061482B discloses a firework composite medicine mixing machine. The medicines in the circular groove body are crushed and ground by the roller, and then the medicine mixing work is performed by the medicine mixing plate moving in a circular motion around the axis of the circular groove body. The mixed medicines are discharged through the discharge holes formed on the circular groove body. In the use process, the medicines in the circular groove body are mixed by relying on the circular motion of the medicine mixing plate. During the movement of the medicine mixing plate, some medicines of the same kind are accumulated on the medicine mixing plate and move with it, so that the other medicines can only be sequentially accumulated and cannot be mixed, resulting in low uniformity of the particles of the produced fireworks. Moreover, the medicine mixing speed is slow due to the circular motion of the medicine mixing plate. After one rotation of the roller for grinding, the medicine mixing plate needs to be idle for several rotations, which results in low overall working efficiency of the equipment. SUMMARY

[0050] The servo motor 24 rotates the rotating cross 2, causing the two rollers 21 and a pusher plate 22 to move in a circular motion around the output shaft of the servo motor. At the same time, the second gear 25 rotates, which in turn causes the gear shaft 26 to rotate. The gear shaft 26 drives all the stirring rods 32 to work through the transmission belt 27 and the third gear 321. Compared with the prior art, the servo motor 24 of the present invention drives all the stirring rods 32 to work, thereby ensuring that the internal stirring effect is the same when all the fixed cylinders 31 are opened in an orderly manner.
