The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Example 1, please refer to Figure 1 、 Figure 2 and Figure 3The output end of the mixing box 4 is connected to the feeding end of the molding machine 5, and the output end of the mixing box 4 is connected to the feeding end of the molding machine 5. The movable frame 8 is located above the discharge end of the molding machine 5, and the walking frame 7 can be moved back and forth on the movable frame 8. The clamp is used to clamp and fix the door core board after molding, and the clamp is fixedly installed at the bottom of the walking frame 7. A rotatable stirring shaft 45 is provided in the mixing box 4, and a plurality of fixedly connected stirring rods 46 are provided on the stirring shaft 45. A plurality of reflux holes 451 are provided on the upper end of the stirring shaft 45. A conveying mechanism for conveying the bottom material to the reflux holes 451 is provided at the bottom of the mixing box 4. A discharge pipe 44 is provided at the bottom of the mixing box 4, and the output end of the conveying mechanism is communicated with the discharge pipe 44. The discharge end of the raw material bin 1 is equipped with a screw feeder 2, which is connected to the feed end of a metering box 6. The metering box 6 is equipped with a powder and water counting chamber. The screw feeder 2 delivers the required amount of gypsum powder for each mold into the powder counting chamber of the metering box 6 for accurate weighing and measurement to ensure no deviation. The metering system is controlled by a PLC. Water is pumped into the water counting chamber of the metering box 6 to ensure no deviation. A dust removal system 3 is also installed on one side of the mixing box 4.

[0029] The design of the stirring shaft 45 and the stirring rod 46 can fully mix and stir the gypsum powder and water in the mixing box 4. The design of the conveying mechanism and the reflux hole 451 can convey the material at the bottom to the reflux hole 451 through the conveying mechanism, and then convey it to the top of the stirring shaft 45 of the mixing box 4 through the reflux hole 451, thereby realizing up and down circulation stirring. Such a stirring design can more fully improve the stirring efficiency of the gypsum powder and make the stirring more uniform. At the same time, the design of the conveying mechanism being connected to the discharge pipe 44 can enable the conveying mechanism to realize material circulation stirring while also realizing automatic discharge of the material through the discharge pipe 44 through the conveying mechanism.

[0030] See also Figure 2 、 Figure 3 and Figure 4In this embodiment, the conveying mechanism includes a conveying pipe 47, which is fixedly connected to the bottom of the mixing box 4, and a prismatic conveying trough is provided in the conveying pipe 47, a rotating shaft 472 is provided in the conveying pipe 47, and the conveying pipe 47 and the stirring shaft 45 are rotated and sealed. A conveying plate 473 that can move up and down is provided in the conveying trough, and the conveying plate 473 and the conveying trough are slidably and sealed. The rotating shaft 472 is connected to the bottom of the stirring shaft 45. A guide hole 453 is provided in the center of the agitator shaft 45, communicating with the reflux hole 451. A connecting hole 476 is provided in the center of the rotating shaft 472, communicating with the guide hole 453. The conveying pipe 47, located at the upper and lower ends of the conveying plate 473, is provided with multiple feed holes, each equipped with a one-way feed valve 471. The rotating shaft 472, located at the upper and lower ends of the conveying plate 473, is provided with multiple discharge holes, communicating with the connecting hole 476, each equipped with a one-way discharge valve 475. The conveying plate 473 is slidably and hermetically connected to the conveying trough.

[0031] The design of the conveying trough, conveying plate 473, one-way feed valve 471, and one-way discharge valve 475 can realize the transportation of materials in the mixing box 4 through the up and down movement of the conveying plate 473. The design of the discharge hole, connecting hole 476 and reflux hole 451 can convey the material at the bottom of the mixing box 4 to the reflux hole 451, thereby realizing the up and down circulation stirring of the material in the mixing box 4.

[0032] See also Figure 3 and Figure 4 In this embodiment, the upper and lower ends of the rotating shaft 472 are rotatably and hermetically connected to the corresponding stirring shaft 45 and mixing box 4. A first control valve 452 is installed in the guide hole 453, and a second control valve 441 is installed in the discharge pipe 44. The discharge pipe 44 is connected to the other end of the communication hole 476. The first control valve 452 and the second control valve 441 are both solenoid valves.

[0033] The design of the first control valve 452 and the second control valve 441 can realize selective material transportation through the first control valve 452 and the second control valve 441, which can realize automatic material discharge and circular stirring.

[0034] See also Figure 4 In this embodiment, a reciprocating thread 474 is provided on the rotating shaft 472 , the rotating shaft 472 passes through the middle of the conveying plate 473 , and the rotating shaft 472 and the conveying plate 473 are connected by the reciprocating thread 474 .

[0035] The design of the reciprocating thread 474 can utilize the characteristics of the reciprocating thread 474 to achieve the up and down periodic movement of the conveying plate 473.

[0036] In this embodiment, the rotating shaft 472 and the stirring shaft 45 are connected to each other in a one-way rotation manner.

[0037] The design of the one-way rotation connection between the rotating shaft 472 and the stirring shaft 45 can prevent the rotating shaft 472 from rotating when the stirring shaft 45 rotates forward. In this way, in the initial stage, the conveying plate 473 will not be driven to move up and down. After stirring for a certain period of time, when the stirring shaft 45 rotates in the reverse direction, the stirring shaft 45 drives the rotating shaft 472 to rotate synchronously. At this time, the reciprocating thread 474 can drive the conveying plate 473 to move up and down. At this time, the material at the bottom of the mixing box 4 can be transported to the top. Through the up and down circulation stirring, the stirring efficiency can be further improved, and a part of the material deposited at the bottom can be transported to the upper end to realize up and down circulation stirring, making the stirring more uniform. The design of combining forward and reverse rotation can better improve the stirring efficiency and make the stirring more uniform.

[0038] See also Figure 4 In this embodiment, the conveying plate 473 is provided with fixedly connected telescopic hoses 477 at both the upper and lower ends. The rotating shaft 472 passes through the middle of the telescopic hose 477. The extended end of the telescopic hose 477 is rotatably and tightly connected to the rotating shaft 472. The design of the telescopic hose 477 improves the sealing between the reciprocating thread 474 and the conveying plate 473.

[0039] See also Figure 1 In this embodiment, a feed pipe 42 and a water inlet pipe 43 are provided at the upper end of the mixing box 4, and a fixedly connected drive motor 41 is provided at the upper end of the mixing box 4, and the output end of the drive motor 41 is fixedly connected to the stirring rod 46.

[0040] When this embodiment is used:

[0041] First, the gypsum powder in the raw material bin 1 is transported to the powder counting chamber in the metering box 6 by the screw feeder 2 for accurate weighing. Water is transported to the water counting chamber in the metering box 6 by the water pump. Then, the gypsum powder and water are sent into the mixing box 4 through the feed pipe 42 and the water inlet pipe 43 through the pipeline.

[0042] Then, the driving motor 41 drives the stirring shaft 45 to rotate in the forward direction, so that the stirring rod 46 drives the gypsum powder and water to be fully stirred. At this time, due to the one-way rotation connection design between the stirring shaft 45 and the rotating shaft 472, the stirring shaft 45 does not drive the rotating shaft 472 to rotate.

[0043] After stirring for a certain period of time, the stirring shaft 45 is driven by the driving motor 41 to rotate in the opposite direction, so that the stirring rod 46 stirs the material in the mixing chamber. At this time, the stirring shaft 45 drives the rotating shaft 472 to rotate synchronously. The rotation of the rotating shaft 472 can drive the conveying plate 473 to move up and down periodically through the characteristics of the reciprocating thread 474, cooperate with the one-way feed valve 471 and the one-way discharge valve 475, and then open the first control valve 452 and close the second control valve 441, so that the material in the mixing box 4 can be conveyed to the reflux hole 451, thereby realizing the up and down circulation conveying of the material, which can more fully stir the material.

[0044] After mixing is complete, the first control valve 452 is closed and the second control valve 441 is opened, allowing the material in the mixing box 4 to be transported to the molding machine 5 through the discharge pipe 44. After the initial setting of the gypsum, the top of the mold is scraped flat using the scraping system. After the final setting of the gypsum, the door core panel formed in the mold is ejected using the hydraulic system. The scraping system and hydraulic system are prior art in the field of the molding machine 5. Their specific structure and principles are prior art, and therefore, this application does not provide a detailed description thereof.

[0045] Then control the walking frame 7 to move above the discharge end of the forming machine 5, and then clamp the door core board with the clamp. After clamping and fixing, move the walking frame 7 to the other end of the mobile frame 8 and place it. After the placement is completed, the workers need to merge the door core boards together and pack them.
