This application provides a device for preventing material misalignment in a binary packaging valve of a
color mixing machine and its usage method. The device includes a tank, a bag
assembly disposed within the tank, a valve body disposed on the bag
assembly, a
discharge assembly disposed on the valve body, and a
discharge component disposed between the valve body and the
discharge assembly. The discharge assembly includes a
valve seat disposed on the tank and a discharge
nozzle disposed on the
valve seat. The discharge component includes a first spring disposed between the discharge
nozzle and the valve body. This device drives the discharge
nozzle to approach the valve body and compress the first spring. The spring's elasticity, combined with the material's
inertia, actively discharges residual material from the discharge nozzle, effectively preventing
viscous material residue from adhering to the valve wall and solidifying, thus preventing material misalignment. It avoids the drawbacks of cumbersome, inefficient, and unstable manual cleaning procedures, improves the adaptability of the binary packaging valve to high-
viscosity materials, and ensures the accuracy of material proportioning in the
color mixing machine. It has the advantages of simple structure, high
raw material utilization, convenient operation, and ease of promotion and implementation.
