Each weighing platform comprises a weighing tube 62, a movable plate 63 and a plurality of weighing sensors 61. The plurality of weighing sensors 61 are annularly arranged at the outer edge of the accommodation hole 210 and are arranged at intervals. The outer wall of the weighing tube 62 is fixedly provided with a flash 620. After the weighing tube 62 penetrates into the accommodation hole 210, the flash 620 on the weighing tube 62 abuts against the top of the plurality of weighing sensors 61. The weighing tube 62 is arranged on the partition plate 21 under the support and limiting action of the flash 620 and is not in contact with the partition plate 21. The movable plate 63 is movably arranged in the weighing tube 62. When the raw material is poured into the weighing tube 62, the weight change of the weighing tube 62 will be transmitted to the weighing sensor through the flash 620, so that the value collected by the weighing sensor changes, and the weighing of the poured raw material is realized. Under the control of the first motor 51 and the limiting action of the connecting plate 54, when the left end of the material taking pipe 4 is inserted into the left raw material tank 3, the right end of the material taking pipe 4 will be located above the right weighing tube 62. When the right end of the material taking pipe 4 is inserted into the raw material tank 3, the left side of the material taking pipe 4 will be located above the left weighing tube 62.

[0057] Figure 6 is an enlarged structural schematic view of B in Figure 3 . Referring to Figure 6 and combining Figure 3The top of the weighing tube 62 is provided with a guide wheel 67, the outer side of the shell 1 is further provided with a second motor 66, the output shaft of the second motor 66 is provided with a winding roller 65, one end of the traction rope 64 is connected with the top of the movable plate 63, the other end of the traction rope 64 extends to the top of the weighing tube 62 and is wound on the winding roller 65 after passing through the shell 1, the second motor 66 rotates forward, the other end of the traction rope 64 will be unwound from the winding roller 65, the movable plate 63 will move downward under the action of gravity, the second motor 66 reverses rotation, the other end of the traction rope 64 will continue to be wound on the winding roller 65, and the movable plate 63 will be pulled upward by the traction rope 64, and the movable plate 63 comprises an integral tapered portion 632 and a cylindrical portion 631, the traction rope 64 is connected with the top of the tapered portion 632, the height of the tapered portion 632 is greater than the height of the cylindrical portion 631, and when the movable plate 63 moves downward to the position that the cylindrical portion 631 is completely below the weighing tube 62, the top of the tapered portion 632 is still located in the weighing tube 62.

[0058] Referring to Figure 2 When the left end of the taking pipe 4 is inserted into the left raw material tank 3 and the right end of the taking pipe 4 is pulled out of the right raw material tank 3 and displaced into the shell 1, the right end face of the taking pipe 4 is located above the right weighing tube 62, and the movable plate 63 is located in the inside of the weighing tube 62, and the weighing tube 62 is in a semi-closed state with the top open, at this time, one hydraulic push rod 42 in the taking pipe 4 acts and pushes the right slider 41 to slide towards the right end face of the taking pipe 4, so that the raw material located between the right slider 41 and the right end face of the taking pipe 4 can be pushed into the right weighing tube 62 and located on the top of the tapered portion 632 of the movable plate 63, so that the value collected by the weighing sensor 61 changes, and the weighing operation of the raw material pushed into the right weighing tube 62 is realized, and the feeding and weighing operation of the raw material in the left weighing tube 62 are consistent with the feeding and weighing operation of the raw material in the right weighing tube 62.

[0060] Further, when one end of the taking pipe 4 finishes taking the raw material and the other end still needs to continue taking the raw material, the end face of the end of the taking pipe 4 that finishes taking the raw material will be closed by the sliding block 41, so that after the end of the taking pipe 4 is inserted into the raw material tank 3, the raw material in the raw material tank 3 cannot enter the taking pipe 4, which ensures that the total amount of the raw material in the corresponding weighing tube 62 will not change, that is, after the sliding block 41 pushes the raw material into the weighing tube 62, if the weight of the raw material in the weighing tube 62 reaches the preset value, the hydraulic push rod 42 will not drive the sliding block 41 to reset, and then the sliding block 41 realizes the closing effect on the end face of the taking pipe 4, and after the sliding block 41 closes the end face of the end of the taking pipe 4 that finishes taking the raw material, it will not affect the taking operation of the other end of the taking pipe 4 that does not finish taking the raw material, that is, the sliding block 41 in the other end of the taking pipe 4 that does not finish taking the raw material will reset under the drive of the hydraulic push rod 42, leaving space for the raw material to enter.

[0061] Referring to Figure 2 and Figure 6The application realizes linear reciprocating driving of the material taking pipe 4 in the horizontal direction through driving of the first motor 51 and cooperation of the screw rod 52, the sliding rod 53 and the connecting plate 54, and then realizes the operation of taking materials in two raw material tanks 3 filled with different raw materials by inserting and pulling out a material taking pipe 4 into the raw material tank 3 reciprocatingly, and respectively weighing after the material taking is completed, and then adjusting the position of the movable plate 63 through adjustment of the winding amount of the traction rope 64 on the winding roller 65 by the second motor 66, that is, when the movable plate 63 is located below the weighing pipe 62, the raw material can be put into the stirring tank through the hopper 2, and when the movable plate 63 is located in the weighing pipe 62, the raw material can be continuously put into the weighing pipe 62 for weighing operation, which effectively improves the weighing and putting efficiency of the raw material; and a plurality of material taking pipes 4 can be arranged in the shell 1, and a plurality of raw material tanks 3 are correspondingly arranged, through staggered arrangement of the plurality of material taking pipes 4 in the shell 1, more kinds of raw materials can be taken, weighed and put without interference between adjacent material taking pipes 4.
