[0029] The proportioning and mixing system for producing PVC cable granules disclosed in this utility model includes the following steps during use:

[0030] When adding raw materials: the operator pours the various raw materials into the corresponding conical raw material bucket 203.

[0031] When coordinating and controlling raw material proportioning equipment and mixing equipment:

[0032] First, the system is initialized: the operator sets the mixing ratio value by using the button panel and display screen according to the mixing ratio and bagging requirements; in the initial state, the rectangular sealing plate 311 is closed on the rectangular connecting frame 317 to prevent unmixed materials from entering the longitudinal conveying auger 308.

[0033] The operator starts the system by pressing the start button on the control panel. When the system starts, the controller first controls the five ratio drive motors 208 to rotate according to the set ratio values ​​through five ratio drive circuits, so that the five raw materials are conveyed to the conveyor belt 225 for unloading according to different conveying times.

[0034] After all the proportioning drive motors 208 have finished working, the controller controls the electric telescopic rod 219 to open the closed rectangular plate 218, and then controls the conveying drive motor 209 and the cleaning motor 210 to rotate, thereby completing one feeding conveyor. After the feeding conveyor is completed, the controller controls the electric telescopic rod 219 to push the closed rectangular plate 218 to close, and then controls the five auger motors 208 to rotate, conveying the five raw materials to the conveyor belt 225 according to different conveying times to wait for the next feeding.

[0035] The mixing process includes: after the raw material proportioning equipment feeds the raw materials to be mixed into the horizontal cylinder 301 through the inclined feeding channel 306, the rectangular sealing plate 218 closes for 3 minutes by default, and the feeding ends. At this time, the controller drives the mixing motor 332 to rotate through the mixing drive circuit to mix the raw materials in the horizontal cylinder 301. After the set mixing time is completed, for example, 20 minutes, the controller controls the sealing motor 314 to pull the rectangular sealing plate 311 to open the rectangular connecting frame 317; then the controller drives the longitudinal drive circuit and the transverse drive circuit to mix the raw materials in the horizontal cylinder 301. The drive circuit drives the longitudinal auger motor 309 and the transverse auger motor 318 to rotate, discharging the mixed raw materials from the vertical discharge pipe 322 and the discharge hose 323. Once all the raw materials in the horizontal cylinder 301 have been discharged, one batch is completed. The controller then controls the sealing motor 314 to push the rectangular sealing plate 311 to close the cylinder. During use, the operator can also temporarily pause and start the longitudinal auger motor 309 and the transverse auger motor 318 using the start and stop buttons to meet temporary manual control needs.
