The directional terms used are for better and clearer explanation and understanding of the present invention, rather than indicating or implying the orientation that the present invention must have, and therefore cannot be understood as limitations on the present invention.
[0026] The utility model is implemented as follows Figures 1 to 7As shown in the figure, a mixing barrel comprises a barrel body 1 of a cylindrical structure, the barrel body 1 adopts a cylindrical structure, a top cover 2 is arranged at the upper end of the barrel body 1, a bottom plate 3 is arranged at the lower end of the barrel body 1, the top cover 2 or the bottom plate 3 is sealed and arranged in the barrel body 1 and can slide along the axial direction of the barrel body in the barrel body; that is, in one case, the top cover 2 is sealed and arranged in the barrel body 1 and slides in the barrel body 1, and the bottom plate 3 is integrally formed with the barrel body 1, such as Figures 1 to 6 Another case is that the top cover 2 and the cylinder 1 are integrally formed, and the bottom plate 3 is sealed and arranged in the cylinder 1 and slides in the cylinder 1, such as Figure 7As shown in ; a top cover through hole 20 is provided at the center of the top cover 2, and the top cover through hole 20 is provided as a countersunk through hole. The countersunk through hole is a through hole whose upper diameter is larger than the lower diameter, and a step is formed between the upper and lower parts. The top cover through hole 20 and the cylinder 1 are coaxial. For example, the top surface of the top cover 2 is provided as a concave spherical top surface, and a column perpendicular to the top surface of the top cover 2 is extended upward from the center of the top cover 2. The center of the column is provided with a top cover through hole 20 that passes through the top surface of the column and the bottom surface of the top cover 2, so that the top cover through hole 20 has a certain length, thereby making the connection structure between the shaftless spiral blade 4 and the top cover 2 more stable, and a cavity with a top cover through hole 20 at the top is formed between the bottom plate 3, the inner wall of the cylinder 1 and the top cover 2. As the top cover 2 descends in the cylinder 1 or the bottom plate 3 rises in the cylinder 1, the volume of the cavity becomes smaller, and the material contained in the cavity can be discharged from the top cover through hole 20. When the bottom plate 2 is sealed in the cylinder 1, the bottom plate 3 can be sealed in the cylinder 1 by a liquid seal or a side wall groove is provided on the side wall of the bottom plate 3 around the side wall of the bottom plate 3, and a sealing ring that partially protrudes from the side wall groove is matched and installed in the side wall groove. At the same time, a bottom surface groove is provided on the bottom surface of the bottom plate 3, and a pushing device that can be matched and inserted into the bottom surface groove can be used to push the bottom plate 3 to slide in the cylinder 1. If the top cover 2 is sealed in the cylinder 1, a liquid seal is adopted between the top cover 2 and the inner wall of the cylinder 1, or a side wall groove is provided on the side wall of the top cover 2, and a sealing ring is provided in the side wall groove.The cylinder 1 is provided with an elastically retractable shaftless spiral blade 4 coaxial with the top cover through hole 20. The shaftless spiral blade 4 is retracted in a manner similar to a telescopic spring. The shaftless spiral blade 4 can use one or more blades. The bottom plate 3 slides upward in the cylinder 1 to exert a force on the shaftless spiral blade 4, and the shaftless spiral blade 4 is compressed accordingly. When the shaftless spiral blade 4 is compressed to the minimum, an annular structure is formed. The outer diameter of the shaftless spiral blade 4 is slightly smaller than the inner diameter of the cylinder 1, that is, there is a small gap between the inner wall of the cylinder 1, so that the shaftless spiral blade 4 rotates in the diameter. The stamping material in the cylinder 1 can be stirred upward without causing the stamping material to accumulate in the cylinder 1. The pitch matches the spacing between the bottom plate 3 and the top cover 2. The lower end of the shaftless spiral blade 4 is pivotally connected to the top surface of the bottom plate 3. The upper end of the shaftless spiral blade 4 is provided with a rotating member 5 with a circular ring structure. The rotating member 5 and the shaftless spiral blade 4 are integrally formed. The rotating member 5 is matched and installed in the through hole 20 of the top cover and can rotate in the through hole 20 of the top cover. The shaftless spiral blade 4 is located between the bottom plate 3 and the top cover 2 and rotates in the cylinder 1. In this way, the material barrel and the stirring blade are combined together, and the shaftless The spiral blades 4 can make the impression material rise up under the action of the shaftless spiral blades 4 and spread and press downward along the barrel 1 to form an 8-shaped spreading and pressing method to blend the impression material. The blending is more uniform and no accumulation occurs at the axis. The impression material is blended in the barrel to avoid the problem of material exposure and dust pollution. Then, the power drive mechanism is connected through the rotating member 5 to realize automatic operation. The driving mechanism can conveniently adjust the stirring speed, pressure and stirring time. The time is short, the stirring efficiency and stirring uniformity are improved, and it can be used without operating experience. At this time, the outer surface of the rotating member 5 The wall extends with an abutment portion 50 that abuts against the step surface in the top cover through hole 20. The abutment portion 50 is arranged on the upper part of the outer wall of the rotating member 5 and forms a T-shaped structure with the rotating member 5. The upper part of the rotating member 5 is matched and sleeved in the upper part of the top cover through hole 20, and the lower part of the rotating member 5 is matched and sleeved in the lower part of the top cover through hole 20. The bottom surface of the abutment portion 50 presses on the step in the top cover through hole 20, preventing the rotating member 5 from falling into the cylinder 1 from the top cover through hole 20. In this way, the upper end of the shaftless spiral blade 4 rotates with the rotation of the rotating member 5, and the lower end of the shaftless spiral blade 4 can rotate relative to the bottom plate 3.When in use, a certain amount of impression material can be pre-loaded into the cylinder 1, and then pure water in a certain proportion to the impression material can be added. The rotating member 5 is connected to an external driving motor, and the cylinder 1 is fixed on a bracket. The driving motor drives the rotating member 5 to rotate, and the rotating member 5 drives the shaftless spiral blades 4 to rotate in the cylinder 1 to achieve the blending of the impression material. During the blending process, the rotation of the shaftless spiral blades 4 makes the impression material rotate in the cylinder 1 and move upward along the axial direction of the cylinder 1. At the same time, the shaftless spiral blades 4 have a downward smearing and pressing effect on the inner wall of the cylinder 1, so that the impression material is mixed more evenly. After the impression material is mixed, the mixed impression material can be pushed out of the barrel by sliding the bottom plate 3. During the sliding process of the bottom plate 3 or the top cover 2, the shaftless spiral blades 4 are compressed and will not affect the sliding of the bottom plate 3 or the top cover 2. It is more convenient to use and there will be no impression material remaining on the inner wall of the cylinder 1.
[0027] Further improvements, such as Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown in , for the pivot connection between the shaftless spiral blade 4 and the bottom plate 3, the lower end of the shaftless spiral blade 4 has a lower extension arm 40 extending toward the axis, and a collar 400 is extended at one end of the lower extension arm 40 away from the shaftless spiral blade 4. A cylinder 30 perpendicular to the top surface of the bottom plate 3 is arranged at the center of the top surface of the bottom plate 3. The collar 400 is matched and sleeved on the cylinder 30 and can rotate relative to the cylinder 30. The collar 400 and the rotating member 5 are coaxial. At this time, a protruding block 401 perpendicular to the top surface of the lower extension arm 40 is extended on the top surface of the lower extension arm 40. The protruding block 401 pushes the mold material on the top surface of the bottom plate 3 and lifts the mold material during the rotation of the shaftless spiral blade 4, so that it will not gather on the top surface of the bottom plate 3, which is more conducive to stirring and mixing, and the mixing is more uniform. The protruding block 401 is a strip-shaped protruding block with a long side perpendicular to the axis of the shaftless spiral blade 4. The side wall of the protruding block 401 in the long side direction is a side wall of an arc-shaped structure concave with an axis perpendicular to the axis of the shaftless spiral blade 4. When the impression material hits the protruding block 401 during the rotation process, it will flow downward along the arc-shaped side wall and turn to reduce the resistance to rotation.
[0028] Further improvements, such as Figures 1 to 3 , Figure 5 and Figure 6As shown in the figure, a plurality of protrusions 51 are arranged at intervals on the inner wall of the rotating member 5, and two adjacent protrusions 51 form a slot, and a notch 52 is arranged on the top surface of the rotating member 5 between two adjacent protrusions 51, and the opening of the notch 52 faces upward, or a notch 52 with an opening facing upward is arranged on the top surface of the rotating member 5 corresponding to each protrusion 51, so that an elastic snap-fit structure is formed, which facilitates the connection between the rotating member 5 and the driving motor. The two are connected by connecting a card block on the output shaft of the driving motor, and a matching snap-fitting portion between two adjacent protrusions 51 is provided on the card block. The notch 52 facilitates the card block to be snapped into the ring of the rotating member 5. At this time, the relative surfaces of the two adjacent protrusions 51 can also be set as a concave arc surface, so that the structure after snapping is more solid.
[0029] Further improvements, such as Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown in the figure, the upper end of the shaftless spiral blade 4 is extended toward the axis with an upper extension arm 41, and the rotating member 5 is arranged at the end of the upper extension arm 41 away from the shaftless spiral blade 4. The upper extension arm 41 shears the stamping material stirred above and presses it downward back into the cylinder 1. When the lower end of the shaftless spiral blade 4 is extended with a lower extension arm 40, the upper extension arm 41 is in a perpendicular state to the lower extension arm 40.
[0030] Further improvements, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown in , the edge of the top of the cylinder 1 is provided with multiple connection mechanisms at intervals along the circumference of the cylinder 1. When the bottom plate 3 is slidably provided in the cylinder 1, the connection mechanism can also be provided at the edge of the top cover 2, or multiple connection mechanisms can be provided at intervals along the circumference of the top cover on the top surface of the top cover 2. Through the connection mechanism, the mixing barrel can be conveniently fixed on the external bracket to facilitate the external drive motor to drive the shaftless spiral blade 4. For the connection mechanism, one case is that the connection mechanism is a block 6 extending from the top edge of the cylinder 1 or the edge of the top cover 2. The block 6 is provided at equal intervals along the circumference of the cylinder 1 at the top edge of the cylinder 1, such as two, three or four blocks 6. The structure is simple and convenient to use. The shape of the block 6 can be a strip block or a U-shaped block; another case is that the connection mechanism is a block 6 extending upward from the top surface of the top cover 1. The block 6 is an inverted L-shaped structure. Also, multiple blocks are provided at equal intervals along the circumference of the top cover 1, such as two or three.
[0031] Further improvements, such as Figure 5 and Figure 6As shown in the figure, two shaftless spiral blades 4 are provided, and the two shaftless spiral blades 4 are symmetrically arranged in the cylinder 1, which is more conducive to the 8-shaped spreading and pressing of the impression material. The lower ends of the two shaftless spiral blades 4 are symmetrically pivoted on the bottom plate 3 along the radial direction, and the upper ends of the two shaftless spiral blades 4 are symmetrically connected to the rotating member 5 along the radial direction. When the lower end of the shaftless spiral blade 4 is extended with a lower end extension arm 40 and the upper end is extended with an upper end extension arm 41, the two lower end extension arms 40 are symmetrically arranged on the outer wall of the collar 400 along the radial direction of the collar 400, and the two upper end extension arms 41 are symmetrically arranged at the lower position of the outer wall of the rotating member 5 along the radial direction of the rotating member 5. The two lower end extension arms 40 and the two upper end extension arms 41 form a staggered structure, which is more conducive to the spreading, pressing, stirring and mixing of the impression material.
