Problems solved by technology

At present, injection molding machines generally use nozzles to discharge materials, but the diameter of the nozzles is small, and it is easy to block during the process of extruding materials. The failure of the whole equipment requires large-scale repairs, which seriously delays the operation, and the materials that stay inside the shell for a long time are easy to harden and agglomerate, which brings more trouble to the maintenance work
[0003] In the publication number "CN109664465B" proposed "an injection molding machine nozzle anti-blocking device and its use method", the patent drives the first gear to rotate through the flow of materials, the first gear drives the driving gear to rotate, and the driving gear passes through the chain Drive the driven gear to rotate, and the driven gear drives the second gear to rotate to realize the anti-blocking of the nozzle, but because the transmission structures such as gears and chains are arranged in the shell, they will contact with the material, and the material remains on the transmission structure, not only It causes waste, and if the material is not treated cleanly, it is easy to harden and agglomerate, resulting in the problem of chain breakage, so that the swing frame cannot perform anti-blocking operations, and the use effect is poor. At the same time, the swing frame can only be set in the nozzle. The residual material remaining on the inner wall of the nozzle cannot be removed, and the residual material on the inner wall of the nozzle is likely to affect the discharge of subsequent materials, and the deblocking effect is poor. For this reason, we propose a nozzle for injection molding machines with an anti-blocking device
