[0020] 2) During operation, when the end clamping piece at one end of the baffle is clamped in the second clamping groove, the positioning rod is clamped in the positioning groove, so that the first motor can drive the stirring shaft to rotate for mixing. When the baffle moves toward the connecting sleeve to clamp the end clamping piece at the other end into the first clamping groove, the first motor can drive the rotating circular plate to rotate. At the same time, the end clamping piece generates a thrust on the bottom end of the longitudinal rod, so that the positioning rod moves upward and disengages from the positioning groove, thereby preventing the stirring rod from affecting the uniform entry of the powdered raw materials into each material box when the powdered raw materials in each material box can be fed evenly.

[0021] 3) During operation, when the baffle moves to the point where the material trough corresponds to the inner cavity of the material box, the round rod is stuck in the round groove, and under the action of the pressure sensor, the transverse plate can accurately move to the top of the powdered raw material in the material box, and during the movement, the transverse sleeve is driven to move downward to push the two rotating plates to rotate and open. The more powdered raw materials in the material box, the greater the downward rotation angle of the rotating plate, and the greater the width of the material discharge gap, so that the material discharge amount per unit time is greater, which is convenient for various powdered raw materials to be fed evenly in proportion;

[0022] 4) During operation, when the top cylinder enters the inner cavity of the material box, the movable block moves upward under the elastic force of the second spring, and when the material trough corresponds to the inner cavity of the material box, the round rod is inserted into the round groove, which facilitates the driving of the two rotating plates to open, and facilitates the discharge of powdered raw materials, and a pressure inclined surface is opened on one side of the movable block to facilitate the return movement;

[0023] 5) During operation, when the set material trough corresponds to the inner cavity of the material box, the two ends of the conductive rod are respectively in contact with the two contacts, so that the electromagnet is energized to drive the clamping rod to disengage from the clamping groove, release the limit on the rotating plate, so that the rotating plate can be rotated and opened, and when the baffle moves back, the clamping rod and the clamping groove are re-engaged, so that after the feeding is completed, the two rotating plates are in a horizontal state to close the material trough, which is convenient for the lateral movement of the baffle inside the plate trough to adjust the position.

Under the action of the pressure sensor 7073, the transverse plate 7072 can accurately move to the top of the powdered raw material in the material box 703, and during the movement, it drives the transverse sleeve 70713 to move downward to push the two rotating plates 7061 to rotate and open. The more powdered raw materials in the material box 703, the greater the downward rotation angle of the rotating plate 7061, and the larger the width of the material discharge gap, so that the material discharge amount per unit time is greater, which is convenient for various powdered raw materials to be fed evenly in proportion.When the top cylinder 7062 enters the inner cavity of the material box 703, the movable block 7063 moves upward under the elastic force of the second spring 7066, and when the material passage 7054 corresponds to the inner cavity of the material box 703, the circular rod 70715 is inserted into the circular groove 7065, which facilitates the driving of the two rotating plates 7061 to open and facilitate the discharge of powdered raw materials, and a pressure inclined surface 7064 is provided on one side of the movable block 7063 to facilitate the return movement.

[0044] Working principle: In the original state, the baffle 7053 is located in a state where the material trough 7054 does not correspond to the inner cavity of the material box 703, and the end clamping piece 7059 of the baffle 7053 away from the connecting sleeve 603 is clamped into the second clamping groove 704, so that the rotating circular plate 702 is fixed to the mixing barrel 1, and then various powdered raw materials that need to be mixed for coating production are respectively put into each material box 703 to complete the loading, and then the mixing pretreatment is carried out;

[0045] Each second motor 7058 is turned on to rotate the first screw 7057. Since the first screw 7057 is threadedly connected to the slider 7056 on the baffle 7053, the baffle 7053 is driven to move toward the side of the connecting sleeve 603. When the material passage 7054 on the baffle 7053 corresponds to the inner cavity of the material box 703, the end clamping piece 7059 on one side of the baffle 7053 is disengaged from the second clamping groove 704, and the end clamping piece 7059 on the other side of the baffle 7053 is clamped into the first clamping groove 605.

[0046] In the original state, the positioning rod 611 at the bottom end of the top plate 608 passes through the through slot 609 and is inserted into the positioning slot 610 at the top end of the top rod 604. When the first motor 5 is turned on, it can drive the stirring shaft 601 to rotate, so that the stirring rod 602 mixes the raw materials. When the end clamping piece 7059 is inserted into the first clamping slot 605, the end of the clamping block 70592 and the bottom end of the longitudinal rod 607 are both hemispherical, thereby pushing the longitudinal rod 607 to move upward, so that the positioning rod 611 moves upward and disengages from the positioning slot 610. At this time, when the first motor 5 is turned on, the rotating circular plate 702 is driven to rotate, while the stirring shaft 601 does not rotate, thereby preventing the stirring rod 602 from affecting the uniform feeding of various powders.

[0047] During the movement of the baffle 7053, when the top cylinder 7062 enters the inner cavity of the material box 703, the movable block 7063 moves upward under the elastic force of the second spring 7066, and when the material trough 7054 corresponds to the inner cavity of the material box 703, the circular rods 70715 on the two horizontal slides 70714 are respectively inserted into the circular grooves 7065 on the two movable blocks 7063, so as to facilitate the opening of the two rotating plates 7061, and a pressure inclined surface 7064 is provided on one side of the movable block 7063, so as to facilitate the movable block 7063 to move downward back to the inside of the top cylinder 7062 under the action of pressure when the baffle 7053 moves back;

[0048] When the material trough 7054 corresponds to the inner cavity of the material box 703, the slider 7056 moves to the position where the two ends of the conductive rod 70614 are in contact with the two contacts 70615 respectively, so that the electromagnet 70613 is energized to generate an attraction force on the magnetic block 70612, thereby driving the clamping rod 70610 to disengage from the clamping groove 7067, releasing the limit on the rotating plate 7061, and when the baffle 7053 moves back, when the circular rod 70715 is still partially inserted in the circular groove 7065, the conductive rod 70614 is separated from the contact 70615, and at this time, the clamping rod 70610 moves back and is clamped into the clamping groove 7067 under the elastic force of the third spring 70611, ensuring that when no material is needed, the two rotating plates 7061 are in a horizontal state to close the material trough 7054, facilitating the lateral movement of the baffle 7053 in the plate groove 7052;

[0049] Then, the third motor 7076 is turned on to rotate the second screw 7075. Since the second screw 7075 is threadedly connected to the end of the hanger 7074, the transverse plate 7072 is driven to move upward. When the powdered raw material is put into the material box 703, the powdered raw material above the transverse plate 7072 generates pressure on the pressure sensor 7073, so that the controller controls the third motor 7076 to remain in the turned-on state. When the transverse plate 7072 moves to the top position of the powdered raw material, the pressure on the top of the pressure sensor 7073 disappears. At this time, the controller controls the third motor 7076 to power off and stop, so as to facilitate the calculation of the amount of powdered raw material in each material box 703. When the transverse plate 7072 moves upward, it drives the first rack 7077 to move upward, and then drives the large gear 7078 to rotate, so that the small gear 70710 rotates synchronously, and the small gear 70710 and the second rack on the side wall of the longitudinal plate 70711 70712 are meshed with each other, and the longitudinal plate 70711 and the first rack 7077 are respectively arranged on both sides of the shaft rod 7079, so that the transverse plate 7072 moves upward to drive the longitudinal plate 70711 to move downward, and the circular rod 70715 at the bottom end of the longitudinal plate 70711 is respectively inserted into the circular groove 7065 on the movable block 7063 above the rotating plate 7061, and the longitudinal plate 70711 moves downward, pushing the two rotating plates 7061 to rotate downward, so that a material discharge gap is formed between the two rotating plates 7061, and the more powdery raw materials in the material box 703, the greater the downward rotation angle of the rotating plate 7061, and the greater the width of the material discharge gap, so that the material discharge amount per unit time is greater, which is convenient for various powdery raw materials to be fed evenly in proportion. At the same time, the diameter of the large gear 7078 is greater than the diameter of the small gear 70710, so that the rotation opening angle of the rotating plate 7061 is adapted to the upward movement of the transverse plate 7072;

[0050] The first motor 5 is turned on to rotate the connecting sleeve 603, driving the rotating circular plate 702 to rotate, and then the powdered raw materials in each material box 703 are fed at a feeding speed adapted to the amount of each powdered raw material, and each material box 703 rotates along with the rotating circular plate 702, so that the powdered raw materials in each material box 703 can be uniformly fed into the mixing barrel 1 at various positions in the circumferential direction of the stirring shaft 601, further improving the feeding uniformity of the powdered raw materials, performing mixing pretreatment on the raw materials, and improving the mixing efficiency and uniformity;

[0051] After the feeding is completed, each component structure is controlled to move back. After the baffle 7053 moves back, the end clamping piece 7059 at one end is disengaged from the first clamping groove 605, and the end clamping piece 7059 at the other end is clamped with the second clamping groove 704. When the end clamping piece 7059 leaves the first clamping groove 605, the top plate 608 moves downward under its own gravity to make the positioning rod 611 clamped into the positioning groove 610. At this time, the first motor 5 is turned on to drive the connecting sleeve 603 to rotate, and then drive the stirring shaft 601 to rotate, so that the stirring rod 602 mixes the raw materials.

[0052] The end clamping member 7059 is composed of a fixed cylinder 70591, a clamping block 70592 and a first spring 70593. When the second clamping slot 704 or the first clamping slot 605 is not in a position corresponding to the end clamping member 7059, the clamping block 70592 can enter the fixed cylinder 70591 under the action of pressure. When the second clamping slot 704 or the first clamping slot 605 corresponds to the end clamping member 7059, the clamping block 70592 is clamped into the second clamping slot 704 or the first clamping slot 605 under the elastic force of the first spring 70593, which is convenient for clamping.
