Description

Technical Field

[0001] The present invention relates to the technical field of instruments and equipment, in particular to a double-axis mixer. Background Art

[0002] Currently, in the field of cosmetic preparation, in order to ensure that the various components of the cosmetics are mixed evenly, a double-axis mixer is generally used for mixing.

[0003] The structure of a dual-axis mixer generally includes a first rotating shaft driven by a motor, etc., and a second rotating shaft driven by the first rotating shaft to rotate around the first rotating shaft. The second rotating shaft is at a certain angle to the first rotating shaft. At the same time, the second rotating shaft is also driven by a motor or other means to rotate around its own axis. A carrying assembly for carrying a cosmetic container is fixed on the second rotating shaft, so that the dual-axis mixer can drive the cosmetic container (packaging material) set on the carrying assembly to rotate around two axes (first rotating shaft and second rotating shaft) at the same time to achieve a better mixing effect.

[0004] With the development of technology, dual-axis mixers are often used as a module in automated equipment. This requires the dual-axis mixer to be able to accurately stop at a preset position so that a robotic arm can grab a container from a carrying component or place a container into a carrying component.

[0005] Currently, the solution for stopping a dual-axis mixer at a preset position is mainly achieved through visual recognition. However, since the mixer requires the dual axes to rotate at a relatively high speed, the motors used are generally high-speed motors. Therefore, it is difficult for the current solution to achieve the purpose of accurately stopping at the preset position, and it is difficult to cooperate with a robotic arm to realize automated production.

Therefore, the above terms cannot be understood as limiting this application.

[0039] Existing dual-axis mixers include:

[0040] A dual-axis rotation assembly includes: a first rotation axis and a second rotation axis, wherein the first rotation axis can drive the second rotation axis to rotate around the first rotation axis; wherein the first rotation axis and the second rotation axis can independently be driving axes or driven axes rotating around their own axes. When they are driving axes, the first rotation axis and the second rotation axis can be, for example, the rotation axes of a motor and / or a pneumatic motor, etc.; when they are driven shafts, the first rotation axis and the second rotation axis can be, for example, driven to rotate by a motor and / or a pneumatic motor, etc. through a transmission member (such as a belt, chain, etc.). Specifically, for example, the first rotation axis is the rotation axis (driving axis) of the first motor 51, and the second rotation axis is the rotation axis (driving axis) of the second motor 52; and,

[0041] The bearing assembly is fixed (directly or indirectly) on the second rotating shaft. The solution of this embodiment is a further improvement of the above solution, such as Figures 1 to 3 As shown, it also includes:

[0042] Rotating assembly 20;

[0043] A driven assembly 30, the driven assembly 30 being fixed (directly or indirectly) to the first rotating shaft (in this embodiment, the fixed portion (housing) of the driven assembly 30 and the second motor 52 are both fixed to the V-shaped frame, thereby achieving indirect fixation of the two);

[0044] a clutch assembly 40 , wherein the clutch assembly 40 is capable of driving the rotating assembly 20 to contact or move away from the driven assembly 30 , and when the rotating assembly 20 is in contact with the driven assembly 30 , the rotating assembly 20 is capable of driving the first rotating shaft to rotate via the driven assembly 30 ;

[0045] A limiting component, which can directly or indirectly detect whether the driven component 30 moves to a preset position.

[0046] The technical solution of this embodiment is based on the existing technical solution, and further adds a rotating component 20, a driven component 30, a clutch component 40, and a limit component, so that after the mixing of the mixer is completed, its dual shafts stop rotating, and the clutch component 40 can drive the rotating component 20 to contact the driven component 30. The rotating component 20 drives the first rotating shaft to rotate through the driven component 30. When the limit component detects that it has rotated to a preset position, it stops rotating, thereby realizing that the carrying component is stopped at the preset position, making it convenient for automated equipment (such as the robotic arm therein) to take and place packaging materials.

[0047] To ensure that the supporting assembly rotates around the two axes during operation, the first and second rotation axes are non-coaxial. Preferably, the angle between the first and second rotation axes is less than 90 degrees, or the two are skewed, thereby improving mixing efficiency.

[0048] In addition, in this embodiment, the carrying component is a storage tube, and the storage tube is coaxially arranged with the second rotating shaft, so as to facilitate the placement of cosmetic packaging materials such as lotion bottles and essence bottles.

[0049] The present application does not specify any specific form of the driven component, as long as it facilitates the rotation of the first rotating shaft by the rotating component. For example, it can be spherical, disc-shaped, etc. In this embodiment, the driven component is a first rotating disk (disc-shaped), which helps reduce the volume of the entire dual-axis mixer.

[0050] At this time, regarding the structure of the rotating assembly, it can include a first moving unit and a second rotating disk 21 provided on the rotating shaft of the first moving unit.

[0051] Preferably, the first turntable has a contact point when in contact with the second turntable 21, and the distance between the contact point and the rotating axis of the first motion unit is smaller than the distance between the contact point and the first rotating axis, thereby realizing a deceleration scheme through the first turntable and the second turntable 21, facilitating more precise stopping at a preset position.

[0052] As for the first motion unit, for example, a motor (preferably a reduction motor) or a pneumatic motor may be cited.

[0053] The present application has no specific limitation on the transmission form of the first turntable and the second turntable 21. For example, the rotation can be driven by static friction. In this case, rubber is preferably provided on the outer peripheral surface of the second turntable 21 to increase friction.

[0054] In this embodiment, Figures 1 to 3As shown, the first turntable is provided with a first tooth surface; the second turntable 21 is provided with a second tooth surface meshing with the first tooth surface; the second turntable drives the first turntable to rotate through the meshing of the second tooth surface with the first tooth surface, thereby making the transmission of the two more stable.

[0055] This application does not specifically limit the position where the first tooth surface is set on the first turntable and the second tooth surface is set on the second turntable, as long as the first tooth surface and the second tooth surface can be easily engaged. For example, the first tooth surface is set on the outer circumference of the first turntable, or the first tooth surface is set on the upper surface or lower surface of the first turntable; the second tooth surface is set on the outer circumference of the second turntable, or the second tooth surface is set on the upper surface or lower surface of the second turntable. In this embodiment, to facilitate contact and separation between the two, the tooth surfaces are both set on the outer circumference of the turntable.

[0056] Regarding the clutch assembly, in this embodiment, as Figure 3 As shown, it includes:

[0057] A second motion unit 41 , which is capable of driving the rotating assembly 20 to contact or move away from the driven assembly 30 ;

[0058] a slide rail 42 , the slide rail 42 being directly or indirectly fixed to a fixed end of the second motion unit 41 ;

[0059] The slider 43 is provided on the fixed end of the rotating assembly 20 , and the slider 43 can slide on the slide rail 42 .

[0060] Therefore, the second moving unit 41 , the slide rail 42 , and the slider 43 can ensure stable contact between the rotating component and the driven component.

[0061] As for the second motion unit, for example, a cylinder or an electric push rod can be cited.

[0062] Regarding the limiting component, it can include: a limiting mark 60, which is directly or indirectly fixed on the driven component; and a sensor 70, which can detect the limiting mark.

[0063] The limiting mark can be implemented as a positioning protrusion or a positioning hole, and in this embodiment, it is specifically a limiting protrusion.

[0064] An existing photoelectric sensor can be used as the sensor 70. Regarding the location of the sensor 70, it can be directly or indirectly fixed on the first motor 51, or fixed on the clutch assembly 40. In this embodiment, the sensor 70 is specifically fixed on the clutch assembly 40.

[0065] Although the embodiments of the present application are described above, the present application is not limited to the above-mentioned specific embodiments and application fields. The above-mentioned specific embodiments are merely illustrative and instructive, and not restrictive. A person of ordinary skill in the art, guided by this specification and without departing from the scope of protection of the claims of this application, may also devise various forms, all of which fall within the scope of protection claimed in this application.
