Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example: Please see Figure 1-5 A raw material mixing and stirring machine for extruded board processing includes a tank body 1. The bottom of the tank body 1 is integrally formed with a feeding pipe 7. A cover 6 is internally threaded to the feeding pipe 7. The cross-section of the cover 6 is mountain-shaped. The protruding part in the middle of the cover 6 is at the same level as the inner wall plane of the bottom of the tank body 1, so that the inner wall of the bottom of the tank body 1 is a closed plane. A feeding port 5 is opened at the bottom of the tank body 1. The feeding port 5 is connected to the feeding pipe 7, and the top of the feeding port 5 is flush with the top of the cover 6 inserted into the feeding pipe 7. When using, first put the raw material into the tank 1. The raw material will be evenly distributed on the closed bottom inner wall, avoiding the accumulation and residue of raw material due to the bottom depression or gap. Since the protruding part in the middle of the cap 6 is flush with the inner wall of the bottom of the tank 1, the raw materials can be smoothly stirred during the stirring process without any dead corners, and the mixing efficiency and uniformity are effectively improved. After mixing, simply unscrew the cap 6, and the mixed raw materials can be smoothly discharged through the discharge pipe 7. The whole process is convenient and can minimize the waste of raw materials. At the same time, the cap 6 can seal the tank 1, making the inside of the tank 1 a sealed space, which can reduce heat loss and make the temperature inside the tank 1 easier to control. This is conducive to maintaining the stable environment required for the raw material mixing reaction and improving the quality stability of the final product.

[0022] In addition, the mountain-shaped cover 6 design enhances its structural strength, making it less prone to deformation or damage during frequent twisting operations, thus extending the overall service life of the equipment. The threaded connection not only ensures a tight fit between the cover 6 and the feed pipe 7 to prevent raw material leakage, but also allows operators to quickly disassemble for cleaning or replacement according to actual needs, further improving the flexibility of equipment use and the convenience of maintenance.

[0023] In this utility model, a motor 4 is fixed to one side of the outer wall of the tank 1 by bolts, and a stirring frame 3 is rotated on the top inner wall of the tank 1 by bearings. The stirring frame 3 and the motor 4 transmit power through a belt and a pulley. After the motor 4 is started, its output shaft drives the stirring frame 3 to rotate at high speed in the tank 1 through the transmission action of the belt and pulley. The stirring blades on the stirring frame 3 then fully stir the raw materials in the tank. By utilizing the shear force and axial thrust generated by the rotation, raw materials with different properties are quickly mixed. During the mixing process, the rotation trajectory of the mixing rack 3 will cover most of the internal space of the tank 1. Combined with the design of the cap 6 being flush with the bottom of the tank 1, it further ensures that the raw materials are mixed without dead corners, improving the uniformity and efficiency of mixing. Meanwhile, the speed of motor 4 can be adjusted according to the characteristics of the raw materials and the mixing requirements. By controlling the speed, it can adapt to the mixing needs of different raw materials, which avoids raw material splashing or excessive shearing caused by excessive speed, and also prevents insufficient mixing caused by excessive speed, thus providing suitable power conditions for the raw material mixing reaction.

[0024] It should be noted that motor 4 is a servo motor with an encoder, and the number of rotations and rotation angle of the motor output shaft are controllable and highly accurate. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0025] Furthermore, multiple feeding pipes 2 are fixed to the outer circumference of the tank body 1 by bolts. Each feeding pipe 2 is equipped with an electric control valve, and the multiple feeding pipes 2 are connected to an external vacuum feeder. When different types of raw materials need to be added to the tank 1, the operator can open the corresponding electric control valve on the feeding pipe 2 through the control system. The external vacuum feeder will then use the negative pressure to transport the raw materials from the storage device to the feeding pipe 2. Subsequently, the raw materials enter the tank 1 under the combined action of their own gravity and vacuum suction. This vacuum feeding method can effectively prevent dust from being generated during the feeding process, maintain a clean operating environment, and reduce material waste. The multiple feeding pipes 2 allow different raw materials to be added simultaneously or at different times. Combined with the stirring action of the stirring rack 3, the newly added raw materials can be quickly integrated into the existing mixing system, shortening the overall mixing cycle. In addition, the precise control of the electronic valve allows for accurate adjustment of the feeding amount. By setting the feeding time and valve opening degree for each feeding, strict control over the ratio of different raw materials can be achieved, meeting the precise requirements of different mixing processes for the amount of raw materials added. This further ensures the stability and consistency of the raw material mixing reaction, and can also seal the feeding pipe 2 of tank 1 to reduce heat loss.

[0026] As a further embodiment of this utility model, the outer circumferential wall of the tank 1 is fixed with a frame by bolts, the bottom inner wall of the frame is slidably connected with a movable frame 8 by a guide rail, the top of the movable frame 8 is provided with a rotatable support column 9, and the top of the support column 9 is fixed with a guide frame 10 by bolts. When discharging the raw material in tank 1, move the moving frame 8 to below the discharge port 5, unscrew the cover 6, and the raw material will fall into the guide frame 10 through the discharge port 5 under the action of gravity. Then, the operator can rotate the support column 9 as needed to adjust the orientation of the guide frame 10 so that the raw material can be accurately guided into the collection container. The design of the movable frame 8 and the guide rail allows the guide frame 10 to be flexibly adjusted in position, which can accurately connect with the discharge port 5 and is easy to remove after the raw material is discharged, making it convenient for the installation and removal of the cover 6. Meanwhile, the rotatable structure of the support column 9 increases the flexibility of material guiding, can adapt to different container placement positions, and improves the operational convenience and efficiency in the raw material discharge process.

[0027] Furthermore, U-shaped frames 14 are welded to both ends of the top of the mobile frame 8. An installation groove is provided on one side of the inner wall of the U-shaped frame 14, and an elastic ball 13 is bonded in the installation groove. Multiple support blocks 11 are welded to both sides of the frame. An arc-shaped groove 12 is provided on one side of the support block 11, and the elastic ball 13 is located in the arc-shaped groove 12. When the movable frame 8 slides on the guide rail, the U-shaped frame 14 will move synchronously with the movable frame 8. At this time, the elastic ball 13 contacts the arc groove 12 of the support block 11 and generates compression. The elastic ball 13 deforms under the compression and its surface is tightly attached to the inner wall of the arc groove 12. The position of the movable frame 8 can be fixed by the friction between the two and the rebound force of the elastic ball 13. When the position of the movable frame 8 needs to be adjusted, the operator only needs to apply a certain pushing or pulling force to make the elastic ball 13 disengage from the current arc groove 12 and be squeezed and deformed, which can drive the movable frame 8 to slide on the guide rail. When it slides to the arc groove 12 of the target support block 11, the elastic ball 13 will be re-inserted into the arc groove 12 under its own elasticity, thus completing the fixation of the new position. This structural design eliminates the need for additional locking devices. The movable frame 8 can be quickly positioned at different locations by the cooperation of the elastic ball 13 and the arc-shaped groove 12. This not only avoids the deviation of the material guide caused by accidental sliding of the movable frame 8 during the material discharge process, but also simplifies the operation steps of position adjustment, further improving the stability and convenience of the equipment. The multiple support blocks 11 provide multiple fixed points for the movable frame 8, allowing the guide frame 10 to be fixed in different positions according to actual operation requirements, thus enhancing the overall adaptability of the equipment.

[0028] Furthermore, a fixing ring 15 is welded to the top of the movable frame 8, and one end of the support column 9 is located between the fixing ring 15 and the movable frame 8. A threaded hole is opened on the top of the fixing ring 15, and a fixing screw 16 is threaded into the threaded hole. By rotating the fixing screw 16, its bottom end can be tightly abutted against the top end of the support column 9, thereby firmly clamping the support column 9 between the fixing ring 15 and the movable frame 8. This detachable connection method simply requires loosening the fixing screw 16 to release the support column 9 from the fixation, making the operation simple and efficient, and further optimizing the connection stability and structural flexibility between the support column 9 and the movable frame 8.

[0029] The guide frame 10 is inclined, and the bottom of the guide frame 10 is higher than the bottom inner wall of the frame. This inclined angle design can accelerate the downward speed of the raw material by using gravity and avoid the raw material from accumulating and lingering on the surface of the guide frame 10. The height difference between the bottom of the guide frame 10 and the bottom inner wall of the frame provides sufficient buffer space for the raw material to fall into the subsequent processing area, which can facilitate the placement of the subsequent receiving device directly under the guide frame 10, further improving the continuity and reliability of the entire raw material conveying process.

[0030] The specific steps for using this utility model are as follows: The operator opens the corresponding electric valve on the feeding pipe 2 through the control system. The external vacuum feeder will then use the negative pressure to transport the raw material from the storage device to the feeding pipe 2. The raw material then enters the tank 1 under the combined action of its own gravity and vacuum suction. When the motor 4 is started, its output shaft drives the stirring frame 3 to rotate at high speed inside the tank 1 through the transmission action of the belt and pulley. The stirring blades on the stirring frame 3 then fully agitate the raw materials in the tank. By utilizing the shearing force and axial thrust generated by the rotation, raw materials with different properties are quickly mixed. The cap 6, in conjunction with the electronically controlled valve, seals the tank 1, creating a sealed space inside the tank 1. This reduces heat loss and makes it easier to control the temperature inside the tank 1, which helps maintain the stable environment required for the raw material mixing reaction and improves the quality stability of the final product.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
