B.ZJ-I automatic shoulder injection machine is a high-tech new type of hose injection special machine for shoulder injection independently developed by our company. All actions of this type of shoulder injection machine are controlled by large-scale PL.C intelligent control touch screen man-machine actual operation, integrating machine, electricity and gas, with high production efficiency, low energy consumption, easy operation, automatic fault alarm, It has the advantages of stable performance and no three wastes. Using the methods of injection, spit, extrusion and welding, plastic shoulders can be injected into aluminum-plastic composite pipes and plastic pipes. The shoulders produced have no clamping stitches, and the appearance is elegant and stable.

This equipment can be matched with the B.GLS-II composite hose pipe-making machine produced by our company to form a fully automatic pipe-making production line, and can also be matched with other pipe-making machines to produce plastic hoses. Compared with the shoulder injection machine used in my country today, this equipment has the characteristics of higher material utilization rate and lower labor intensity.

The equipment mainly includes: full servo operation mechanism, automatic pipe feeding mechanism, quantitative plastic injection mechanism, mold clamping and forming mechanism, mold release separation mechanism, automatic pipe unloading mechanism, automatic feeding mechanism, etc.

The device has been awarded two patents. respectively：

Patent No. ZL200420027317.6 The plastic injection mechanism of the shoulder injection machine；

Patent No. ZL200420027315.7 Mould overturning locking device of shoulder injection machine.
