[0040] The raw material mixing system for producing PVC cable materials disclosed in the present invention comprises the following steps during operation:

[0041] When the raw material lifting equipment is in operation: the operator places the raw material bag on the lifting supporting plate 105. If the raw material in a conical raw material barrel 203 is insufficient, the rear side of the feeding extension plate 122 is lifted by the U-shaped handle rod 124, and the feeding extension plate 122 is slid together with the sliding seat 107 to the corresponding conical raw material barrel 203, and then the feeding extension plate 122 is lowered so that the rear side of the feeding extension plate 122 extends into the upper opening of the conical raw material barrel 203. The height of the lifting supporting plate 105 is controlled by the lifting button 112 and the lowering button 113 according to the lifting needs. The operator can easily insert the opening of the raw material bag into the limiting ring formed by the U-shaped handle rod 124, the material blocking flange 123 and the feeding extension plate 122, and push the raw material bag to pour the raw material onto the feeding extension plate 122, so that the raw material slides along the feeding extension plate 122 into the corresponding conical raw material barrel 203 for raw material replenishment.

[0042] When the raw material proportioning equipment and the stirring and mixing equipment are coordinated and controlled: first, the system is initialized: the operator sets the proportioning ratio and weighing value according to the proportioning and bagging requirements through the cooperation of the key panel and the display screen; the operator then clamps the upper mouth of the raw material bag between the upper side of the bag support ring 331 and the L-shaped clamping rod 327; in the initial state, the rectangular closing plate 311 is closed on the rectangular connecting frame 317 to prevent unmixed materials from entering the longitudinal conveying auger 308.

[0043] The operator starts the system by pressing the start button on the key panel. When the system starts, the controller first controls the five proportioning drive motors 208 to rotate according to the set proportions through the five proportioning drive circuits, and transports the five kinds of raw materials to the conveyor belt 225 according to different conveying times to wait for unloading.

[0044] 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 material unloading and conveying. After the unloading and conveying is completed, the controller controls the electric telescopic rod 219 to push the closed rectangular plate 218 to close it, and then controls the five auger motors 208 to rotate, and conveys the five kinds of raw materials to the conveyor belt 225 according to different conveying times to wait for the next unloading.

[0045] The stirring process includes: after the raw material proportioning equipment conveys the raw materials to be stirred into the horizontal cylinder 301 through the inclined feeding channel 306, the closed rectangular plate 218 is closed for 3 minutes by default and the material feeding is completed. At this time, the controller drives the stirring motor 332 to rotate through the stirring driving circuit to stir the raw materials in the horizontal cylinder 301. After the set stirring time is completed, for example, 20 minutes, the controller controls the closed motor 314 to pull the rectangular closed plate 311 to open the rectangular connecting frame 317; the controller then drives the longitudinal auger motor 309 and the transverse auger motor 318 to rotate through the longitudinal driving circuit and the transverse driving circuit respectively, and the three weighing sensors 324 perform real-time weighing. The controller then uses the weighing increment values ​​of the three weighing sensors 324 as the actual raw material bagging weight. When the raw material bagging weight reaches the set weighing value, the controller controls the longitudinal auger motor 309 and the transverse auger motor 318 to stop working, and then the operator removes the seal of the bag to complete the single bag discharging process; the above-mentioned single bag discharging process is repeated until the set number of repetitions is completed, that is, a batch is completed, and the controller controls the closing motor 314 to push the rectangular closing plate 311 for closing; during use, the operator can also use the start button and the stop button to temporarily pause and start the longitudinal auger motor 309 and the transverse auger motor 318 to meet the temporary manual control needs.
