[0046] like Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 As shown:

[0047] The mixing device includes a slide rail 101 and a magnetic separation plate 501. A movable seat 102 is connected to the slide rail 101, and an adding part 103 is rotatably connected to the movable seat 102. A sliding ring 104 is fixedly connected to the adding part 103, and a baffle plate 301 is slidably connected to the sliding ring 104. A contact head 302 is connected to the baffle plate 301, and an arc-shaped spring is fixedly connected between the baffle plate 301 and the sliding ring 104. A filter part 406 is slidably connected to the magnetic separation plate 501, and a mixing arc plate 401 is slidably connected to the filter part 406. The filter part 406 has multiple through holes, and two side baffles 402 are fixedly connected to the filter part 406. The front side baffle 402 has an arc-shaped groove 403, through which the mixing arc plate 401 can slide out. A transmission block 404 is fixedly connected to the filter part 406. A mating gear ring is rotatably connected to the seat 102, a transmission gear is fixedly connected to the adding part 103, an agitator 105 is rotatably connected to the moving seat 102, and an auxiliary gear ring is fixedly connected to the agitator 105. The mating gear ring, the transmission gear, and the auxiliary gear ring are all in a meshing state. The contact head 302 can contact the transmission block 404. A first motor that can drive the adding part 103 to rotate is fixedly connected to the moving seat 102. A second motor is fixedly connected to the filtering part 406. A first lead screw is fixedly connected to the output shaft of the second motor. The first lead screw is threadedly connected to the mixing arc plate 401. An agitator is detachably connected to the agitator 105 by bolts. A first compression spring is fixedly connected between the filtering part 406 and the magnetic separation plate 501. A through groove is provided on the adding part 103. Under normal conditions, the baffle plate 301 can block the through groove.

[0048] The slide rail 101 is fixed to a hydraulic cylinder by screwing bolts into it, and the magnetic separation plate 501 is fixed by screwing bolts into it. The hydraulic cylinder can push the slide rail 101 up and down, thereby adjusting the initial height of the adding section 103 according to the different material weights and the height of the filter section 406. When using this equipment, the antioxidant material powder is added to the adding section 103, and then the mixing arc plate 401 is slid to... Figure 9 As shown, the mixing arc plate 401 blocks multiple filter holes on the filter section 406. Then, glaze raw material fragments are added to the upper side of the mixing arc plate 401, causing the fragments to automatically accumulate at the center of the mixing arc plate 401. The adding unit 103 then rotates on the moving seat 102, causing the stirring unit 105 to rotate via meshing gear rings, transmission gears, and auxiliary gear rings, thereby agitating the material on the mixing arc plate 401. During the rotation of the adding unit 103, the blocking plate 301 rotates synchronously with the adding unit 103. Figure 6It is known that the transmission block 404 has an arc-shaped edge and a straight edge. When the baffle plate 301 rotates clockwise until the contact head 302 contacts the transmission block 404, it will be pushed by the transmission block 404, causing the baffle plate 301 to slide on the sliding ring 104 against the elastic force of the arc-shaped spring, thereby exposing the through groove on the adding part 103, and then some of the antioxidant material fragments will be sprinkled out from the adding part 103. Then, in conjunction with the rotating stirring part 105, the falling antioxidant material fragments and the original glaze raw material fragments will be continuously stirred, thereby completing the effect of automatically adding solid materials in batches for mixing, and improving the mixing efficiency.

[0049] When there is no need to add antioxidant material powder, the operable addition part 103 can be continuously rotated clockwise, so that the contact head 302 contacts the arc-shaped edge of the transmission block 404. Since the force effect of the arc-shaped edge is different from that of the straight edge, after the contact head 302 contacts the arc-shaped edge of the transmission block 404, it can gradually push the transmission block 404 upward through the arc-shaped edge, so that the filter part 406 overcomes its own weight and the elastic force of the first compression spring and slides upward. Then, by operating the continuous rotation of the addition part 103, the mixing arc plate 401 can be intermittently slid up and down, so that the material on the mixing arc plate 401 is constantly shaking, which, together with the continuous stirring of the stirring part 105, improves the material mixing efficiency. At the same time, the stirring depth of the stirring part 105 can be continuously changed to further improve the mixing efficiency.

[0050] When all the antioxidant material fragments in the addition section 103 fall down and are evenly mixed with the glaze raw material fragments, the operable mixing arc plate 401 slides on the filter section 406, thereby sliding the filter section 406 out of the arc groove 403, exposing multiple through holes. This allows the material on the filter section 406 to fall through the multiple through holes to the contact position with the magnetic separation plate 501, and the material rolls down naturally along the magnetic separation plate 501. The magnetic separation plate 501 then adsorbs the magnetic metals in the material, achieving an automatic magnetic separation effect and improving preparation efficiency.

[0051] like Figure 5-8 As shown:

[0052] The device also includes an inclined plate 405 fixedly connected to the transmission block 404, the contact head 302 is slidably connected to the baffle plate 301, and a second compression spring is fixedly connected between the contact head 302 and the baffle plate 301.

[0053] When it is necessary for the antioxidant material fragments in the adding part 103 to fall, the adding part 103 can be rotated counterclockwise, causing the baffle plate 301 to gradually rotate synchronously with the adding part 103. When the contact head 302 moves to the contact position with the inclined plate 405, the contact head 302 will be gradually pushed by the mixing arc plate 401, causing the baffle plate 301 to gradually slide on the sliding ring 104 against the elastic force of the arc spring, thereby gradually exposing the through groove and performing the feeding of the antioxidant material fragments. At this time, the slide rail 101 can be operated to move upward, causing the contact head 302 to be pushed by the inclined plate 405 and gradually retract into the baffle plate 301. The contact head 302 slides in the 01 direction, allowing it to gradually separate from the mixing arc plate 401. Once the contact head 302 is completely separated from the mixing arc plate 401, the arc spring gradually pushes the baffle plate 301 back to its original position, thus blocking the channel again and achieving the effect of periodically adding antioxidant material fragments. The sliding arrangement of the inclined plate 405 and the contact head 302 allows the operation adding part 103 to rotate counterclockwise continuously and move upward in conjunction with the slide rail 101 to complete the periodic feeding operation. The opening time of each channel can be adjusted by adjusting the upward movement speed of the slide rail 101, thus facilitating efficient mixing according to production needs.

[0054] like Figure 8 As shown:

[0055] The device also includes a rotating plate 502 rotatably connected to the magnetic separation plate 501, two side plates 503 fixedly connected to the rotating plate 502, a third motor fixedly connected to the magnetic separation plate 501, the output shaft of the third motor fixedly connected to the rotating plate 502, the movable seat 102 slidably connected to the slide rail 101, a fourth motor fixedly connected to the slide rail 101, a second lead screw fixedly connected to the output shaft of the fourth motor, and the second lead screw threadedly connected to the movable seat 102.

[0056] The rotating plate 502 is designed so that during the actual operation of this equipment, the rotating plate 502 can be rotated to... Figure 8 The posture shown allows the material falling from the multiple through holes on the filter section 406 to be guided by the rotating plate 502 and slide down only from the right side of the magnetic separation plate 501. Thus, only the right half of the magnetic separation plate 501 is used for magnetic separation of the material. At this time, the operator can collect and remove the remaining magnetic metal powder on the left half of the magnetic separation plate 501. After the collection is completed, the rotating plate 502 is rotated 90° to use the left half of the magnetic separation plate 501 to collect the magnetic metal powder. This allows the accumulated magnetic metal powder to be cleaned without stopping the equipment, providing convenience for the operator.

[0057] During the process of the material falling through the through hole on the filter section 406, the rotating plate 502 can be periodically moved to a position where it can contact the mixing arc plate 401. Then, by operating the moving seat 102 to slide on the slide rail 101, the contact head 302 moves the arc edge of the transmission block 404, thereby gradually pushing the filter section 406 upward. When the contact head 302 is displaced from the transmission block 404, the mixing arc plate 401 can be quickly reset downward by the elastic force of the first compression spring, thereby causing the lower side of the filter section 406 to contact the rotating plate 502, causing the filter section 406 to impact and vibrate slightly, thereby shaking down the material adhering in the through hole, thus avoiding the situation where some material is blocked in the through hole and cannot be discharged, and facilitating the complete discharge of the material.

[0058] Before performing the power-charging and striking operation, the adding part 103 can be rotated to a certain angle to adjust the starting angle of the contact head 302, thereby adjusting the power-charging and striking force, which further facilitates the full shaking of the material.

[0059] like Figure 4 , Figure 10 As shown:

[0060] The device also includes a slide block 201 slidably connected to the movable seat 102, a cleaning brush 202 rotatably connected to the slide block 201, a third compression spring fixed between the slide block 201 and the movable seat 102, and a fifth motor capable of driving the cleaning brush 202 to rotate fixedly connected to the slide block 201.

[0061] When the movable seat 102 slides on the slide rail 101 and works with the rotating plate 502 to strike the filter section 406, the slide 201 slides synchronously with the movable seat 102. With the help of the spring force of the third compression spring, the cleaning brush 202 is pressed tightly against the lower side of the filter section 406. As the movable seat 102 moves, the cleaning brush 202 gradually brushes different through-hole positions on the lower side of the filter section 406. At the same time, the cleaning brush 202 rotates continuously on the slide 201, thereby improving the brushing effect and further removing the material adhering to multiple through-holes. This prevents some material from blocking the through-holes and being unable to be discharged, and facilitates the complete discharge of material.
