[0001]

[Industrial applications]

 The present invention relates to a kind of dental impression material stirrer, and more particularly to a stirrer which can stir materials uniformly, do not generate bubbles in the materials, and can stir in a short time by high speed rotation.

[0002]

[Prior art]

 The impression is a negative shape in the mouth taken for making a denture in dentistry, but the material is generally used after adding water to the impression powder and stirring it by hand to make it viscous. Since this material solidifies within a fixed time, the user can stir for a limited time, and therefore the impression material cannot be stirred uniformly. In addition, the method of stirring by hand was force-consuming, tended to generate bubbles in the material, and pores were formed in the manufactured impression to roughen the surface, greatly affecting the quality of the denture.

【Example】

 1 is a perspective view of the present invention. The rectangular hollow seat 1 of the present invention supports all the constituent members, and the hollow seat 1 has a cylindrical hollow at the center, and a cylindrical single motor housing 2 is installed therein. The four corners of the hollow seat body 1 are vertically vertically extended to provide columns 11, and between the top end of each column 11 and the peripheral edge of the motor housing seat 2, the motor housing seat 2 and each member on the upper surface thereof. A tension spring 3 for suspending the hollow seat 1 in the hollow portion of the hollow seat 1 is provided. The purpose of such a hanging structure is to eliminate the vibration of the hanging member by the elasticity of the tension springs 3 installed in four averages, and to provide the stability when using the stirrer. Is like a dehydration tub of a washing machine, and since the present invention agitates materials by high-speed eccentric rotation, such a seismic design is indispensable structurally. An electric motor is provided inside the electric motor housing 2, and a cylinder 4 and a V-shaped frame 5 that rotate in synchronization with the electric motor are provided at the upper end of the electric motor. Above the V-shaped rack 5, a conical storage tank 7 and a similar planetary gear system are provided. A cylindrical accommodating cup 6 used for accommodating a dental impression material is fixed on the end wheel of the similar planetary gear system. The accommodating cup 6 obliquely penetrates through the conical accommodating tank 7 described above, the opening is inclined upward, and the accommodating cup 6 is revolved and revolved in rotation while the stirrer is in operation, in conjunction with the similar planetary gear system. The revolution and rotation proceed in opposite directions (see arrow in the figure). With this type of design in the direction of rotation, the dental impression material is sufficiently evenly stirred, and the dental impression material is subjected to centrifugal force at high speed to fly outward. However, since the dental impression material is blocked by the inclination design of the inclined storage cup 6 and does not scatter to the outside, air bubbles in the dental impression material that are blown outward and concentrate on the outside of the storage cup 6 are generated. The dental impression material is discharged and is not mixed with the storage cup 6 so as not to continuously leave the outside due to the rotation of the storage cup 6, so that the dental impression material is uniformly mixed. Stirring by this type of method has the effect that the materials can be mixed uniformly and that it is dense and free of bubbles, and the high-speed rotation shortens the stirring time required, while other dental impressions are made. It can be applied to the manufacturing process.

The detailed structure of the aforementioned components is shown in FIG. A single electric motor 8 is tightly installed inside the electric motor accommodating seat 2, a shaft 81 of the electric motor 8 is hollow and is installed vertically upward, and its shaft end is exposed from the upper end of the electric motor accommodating seat 2. The bearing seat 21 used for positioning the shaft 81 of the electric motor 8 is provided at the interface of the shaft 81 that is protruded from the electric motor housing seat 2, and the cylinder 4 is provided at the exposed shaft end of the electric motor 8. The V-shaped rack 5 is fixed to the upper edge of the cylinder 4. The cylinder 4 and the V-shaped frame 5 are synchronously rotated by the transmission of the electric motor, and one sun gear 51 is provided as an axis at the center of the upper edge of the V-shaped frame 5. The sun gear 51 is a bevel gear and has a gear shaft 511 which vertically extends downward and penetrates the hollow shaft 81 of the electric motor 8 described above. The end of the gear shaft 511 is fixed to the center of the bottom edge of the electric motor housing 2. The bearing seat 50 fixed to the upper edge of the V-shaped frame 5 is used for passing the gear shaft 511, and is fixed to the bottom edge of the electric motor housing seat 2 without the sun gear 51 being affected by the rotation of the V-shaped frame 5. . The V-shaped frame 5 has two upwardly sloping arms 56, 56 ', of which one arm 56 is provided with an adjustable weight 55 used to balance the rotating members and the other one. A similar planetary gear system is fixed to one arm 56 '(see FIG. 3). The first planetary gear 52 is a linear bevel gear that meshes with the sun gear 51, and the center line of the first planetary gear 52 is perpendicular to the arm 56 ′ of the V-shaped frame 5 and coaxially with one inertia. A wheel 53 is provided. The inertia wheel 53 is a positive gear and is axially mounted on the arm 56 ', and a second planetary gear 54 meshing with the inertia wheel 53 is further axially mounted on the arm 56' on one side of the inertia wheel 53. The second planetary gear 54 is used for transmitting to the receiving cup 6 for rotation. The relative interlocking relationship of such one similar planetary gear system is shown in the arrow direction in the figure. Further, as shown in FIG. 4, when the V-shaped frame 5 driven by the electric motor rotates clockwise, the dental impression material is rotated and stirred around the sun gear 51, and the first planetary gear on the V-shaped frame 5 is agitated. 52 also receives this rotation and is interlocked, rotates clockwise, and rotates in synchronization with it. The inertia wheel 53 is also transmitted to the second planetary gear 54 to rotate counterclockwise, and the second planetary gear 54 is rotated. The driven dental impression material revolves clockwise and rotates counterclockwise, achieving the above-mentioned request to stir the dental impression material, and through this type of rapid and highly efficient stirring method, The stirring time is shorter than manual. When the set rotation time of the electric motor is reached, the electric motor stops rotating, but the driven members continue to rotate due to inertia, so they rotate together with the rotating member in order to stop them quickly and save time. As shown in FIG. 5, a one-belt type braking device 41 is provided by a shaft in the electric motor housing seat 2 outside the circular cylinder 4, which is fixed at the shaft contact end 40 and is applied by the force 41 to the movable end. It is a member that controls the friction between the brake 41 and the cylinder 4 and thus stops the rotation.

The mechanical structure of the present invention is operated and controlled by the control circuit, and the user simply puts the powdery dental impression material and water into the receiving cup 6, and then controls the rotation time by the control face plate to start. As a result, the present invention enhances the efficiency of the dental impression material agitation work, and eliminates the drawback that the agitation by the conventional driving tends to generate bubbles and is not uniform.

[0009]

[Effect of device]

 The dental impression material agitator of the present invention can uniformly agitate the dental impression material without generating bubbles in the material, and its high speed rotation can shorten the required agitation time.
