In order to be able to put in a sufficient amount of clay material at a time, the space above the mixing component is large. During the mixing process, the additives need to be fully stirred in the mixing component before they can come into contact with the clay material in other positions, which leads to low mixing and blending efficiency.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1-9 , the present invention provides the following technical solutions:

[0030] Example 1: The solution disclosed in this example is to solve the problems existing in the prior art, such as Figure 1-Figure 2As shown, it includes a body 1 and two rotating shafts 2 symmetrically distributed inside it, wherein the right end of one rotating shaft 2 is connected to the motor, and the left ends of the two rotating shafts 2 are connected by two mutually meshing transmission gears 3, and the rotating shaft 2 is used to install a stirring component, and the stirring component includes a hollow plate 4 and an extension portion arranged in the hollow plate 4, wherein the extension portion increases the stirring range by deforming the stirring component as a whole and deforming the stirring component when it rotates above the rotating shaft 2, and the extension portion includes a deformable layer structure covering the opening at the outer end of the hollow plate 4, and the internal structure of the hollow plate 4 covered by the layer structure is connected to the air supply portion, and the air supply portion includes a hollow structure in the rotating shaft 2 connected to the hollow structure inside the hollow plate 4, and the hollow structure is connected to the air supply and air intake pipes rotatably installed at the left end of the rotating shaft 2, wherein the hollow plate 4 is distributed with its outer end facing downward in the initial state, and the layer structure covering its outer end opening In this state, it is a normal or retracted state. During the mixing process of clay, pigment or other materials, the operation of the motor will drive the rotating shaft 2 to rotate and make the hollow plate 4 rotate synchronously along the axis and hit the mixed clay material. The hitting effect can be achieved by existing means such as intermittent control of the motor operation effect. When the hollow plate 4 rotates to the outer end facing upward or tilted upward, air can be supplied to the inside of the rotating shaft 2 through a pipeline through equipment such as an air pump. The air flow directly enters the hollow plate 4 and expands the layer structure, thereby increasing the mixing working range when the hollow plate 4 rotates to the upper material accumulation position, thereby greatly improving the mixing effect. The fixed-point triggering of the air pump air supply can be achieved by a sensor. A sensor or magnetic piece with the same direction as the hollow plate 4 is installed at the end of the rotating shaft 2. After being aligned with the sensor at the corresponding position, an electrical signal is triggered to start or stop the air pump, or the air pump is started and stopped regularly by the rotation speed of the rotating shaft 2.

[0031] Example 2: This embodiment discloses another extension scheme. Compared with the scheme in Example 1, this scheme is more stable in operation and has higher structural strength. At the same time, the extended stirring range generated is larger. Figure 3-Figure 7As shown, the extension portion includes an extension plate 5 that is slidably nested and connected to the inside of the hollow plate 4, wherein the top end of the extension plate 5 can slide through the outer end opening of the hollow plate 4, and the inner end of the extension plate 5 is connected to a driving mechanism, wherein the driving mechanism is used to drive the extension plate 5 to extend or retract when the hollow plate 4 rotates to a specified position, and the driving mechanism includes a vertical shaft 6 rotatably installed in the hollow plate 4 and the rotating shaft 2, the outer end of the vertical shaft 6 is threadedly connected to the extension plate 5 through a single-rotation reciprocating thread set on the surface, and the vertical shaft 6 rotates at a specified position when the hollow plate 4 rotates around the axis of the rotating shaft 2, and the bottom end of the vertical shaft 6 is installed with a main gear 7 located in the rotating shaft 2, which rotates around the axis of the rotating shaft 2 to the upper side and engages with the tooth groove on the fan-shaped bevel gear 8, wherein the fan-shaped bevel gear 8 is fixed on the horizontal shaft 9, and the horizontal shaft 9 is rotatably connected to the rotating shaft 2, and the left end of the horizontal shaft 9 passes through the rotating shaft 2 and is fixed in the body 1. The operation of the motor will drive the rotating shaft 2 to rotate. At this time, the vertical shaft 6 can be regarded as a part of the rotating shaft 2 and revolve around the axis. Therefore, the main gear 7 of the bevel gear structure installed at the bottom end of the vertical shaft 6 will revolve synchronously. When the vertical shaft 6 rotates to a position above the axis of the rotating shaft 2, the main gear 7 at its bottom end will begin to engage with the tooth structure of the fan-shaped bevel gear 8. Therefore, continued revolution will cause the vertical shaft 6 to be in a rotating state under the action of the gear meshing transmission. At this time, under the transmission action of the threaded structure on its surface, the extension plate 5 will move and extend out in the hollow plate 4, and in the second half of the engagement of the main gear 7 and the fan-shaped bevel gear 8, the vertical shaft 6 will drive the extension plate 5 to retract, thereby preventing the stirring component from affecting the bottom wall structure of the body 1.

[0032] The solution disclosed in this embodiment is to improve the mixing efficiency of clay materials and materials with good fluidity such as pigments. Specifically, in order to control time and economic costs, the mixing of such materials in the prior art is often done by directly pouring them before mixing, so as to coordinate with the operation of the subsequent stirring component for mixing and blending. However, clay materials are different from other fluids and have greater stirring resistance. Therefore, the pigments and other mixed materials initially stay on the surface of the clay materials in the mixer, and the efficiency during the mixing process is low. Therefore, Figure 8-Figure 9As shown, an opening is provided at the end of the extension plate 5, which is connected to the output end of the one-way channel 12 arranged in the extension plate 5, and the output end of the one-way channel 12 is connected to the output end of the conveying space 13. The conveying space 13 is formed between the inner end of the extension plate 5 and the inner end of the hollow plate 4. The space changes with the movement of the extension plate 5, and the input end of the conveying space 13 is connected to the through hole 14 opened on the vertical shaft 6, wherein the through hole 14 is connected to the ring body 15 through the internal hollow structure of the vertical shaft 6, and the ring body 15 is rotatably nested on the vertical shaft 6, wherein the vertical shaft 6 is also rotatably connected to the ring body 15, and the output end of the internal hollow structure of the vertical shaft 6 is connected to the ring body 15 through the opening, and the input end is connected to the pipeline rotatably installed at the left end of the rotating shaft 2. The space corresponding to the inner end of the extension plate 5 is designed as a transit space for fluid material transportation. The specific form is that the extension plate 5 is vertical When the shaft 6 moves outward under the drive, the space will be in a negative pressure state, so the pipe containing a one-way valve connected to the left end of the rotating shaft 2 is synchronously in a negative pressure state. The pipe is connected to a container for containing a quantitative fluid, so the fluid in the container, such as pigment, will pass through the rotating shaft 2, the ring body 15, the vertical shaft 6 and the through hole 14 during the extension and movement of the extension plate 5 and enter the conveying space 13. When the main gear 7 and the rear half of the fan-shaped bevel gear 8 are engaged for transmission, the rotating vertical shaft 6 will drive the extension plate 5 to move back, so the fluid in the conveying space 13 will enter the one-way channel 12 which also has a one-way flow restriction and flow out from the opening at the end of the extension plate 5. The advantage of this design is that the fluid contacts the material from the inside of the material from the beginning of the mixing process. The resulting timed and quantitative feeding effect, combined with the rolling of the clay material during the mixing process, can produce better mixing effects and higher efficiency.

[0033] This solution is a further expansion of the above content, specifically Figure 8 As shown, the output end of the conveying space 13 is a counterweight block 10 with a through-channel structure, and the counterweight block 10 is connected to the one-way channel 12 through an elastic connecting tube 11. The extension plate 5 will perform the fluid conveying function in the retracted state, and in this process, the fluid will also produce a flow effect following the rotation of the stirring component. Therefore, the conventional circulation design may cause the input end of the one-way channel 12 to be unable to fully contact with the fluid when the single fluid conveyance is small, thereby affecting the mixing efficiency. Figure 8 and Figure 9 As shown, on the one hand, the counterweight block 10 is the same as the fluid, and will produce the effect of gravity self-movement following the change of the rotation position. Therefore, the counterweight block 10 can maintain contact with the fluid in more cases to ensure the suction and delivery effect. At the same time, the counterweight block 10 can also drive the hollow plate 4 through the motor to produce a variable speed rotation effect and a collision and vibration effect between the counterweight block 10 and the hollow plate 4, thereby improving the mixing effect.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
