Technical Field

[0001] This invention relates to the field of mechanical motion mechanism technology, and in particular to a circular oscillation mechanism design, which has application and promotion value in the field of stirring (fully mixing) fine particulate materials. Background Technology

[0002] There are various designs for material mixing mechanisms, but most achieve this through the rotation of a mixing plate (block) within a container. Some also use vibration, tilting, or rotation. In certain special applications where a non-touch method is required, and where thorough mixing is still necessary, a new mechanism motion design is needed to fulfill this functional requirement. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention discloses a circular oscillation mechanism design. In order to meet the requirements of non-contact operation and thorough mixing of materials, this motion is achieved through structural designs such as a motor, motor output shaft, eccentric sleeve, oscillating disk, elastic barrel sleeve, and outer shell.

[0004] This invention is achieved through the following technical solution:

[0005] A circular oscillating mechanism design includes a motor and an oscillating disk. An eccentric sleeve is fitted onto the end of the output shaft of the motor. The eccentric sleeve is assembled into the bearing cavity of the oscillating disk via a bearing. An elastic barrel sleeve is detachably locked to the circumferential edge of the oscillating disk by screws. A housing is detachably locked to the upper circumferential edge of the elastic barrel sleeve by screws. The lower end of the housing is detachably locked to the upper end face of the motor by screws.

[0006] There is an eccentric angle between the inner hole axis of the eccentric sleeve and the output shaft axis of the motor, and the upper end face of the eccentric sleeve is set in a wedge structure, the angle between the wedge surface and the horizontal plane and the eccentric angle are both 3-5°.

[0007] Preferably, the oscillating disk includes a bearing sleeve and an oscillating disk. The oscillating disk is integrally formed on the outer wall of the bearing sleeve and is set at an inclined angle. The bearing sleeve has a bearing cavity inside, a stop ring is provided at the bottom of the bearing cavity, and an annular groove is provided at the upper part of the bearing cavity.

[0008] Preferably, the bottom of the eccentric sleeve is provided with a keying groove, the upper part of the outer wall of the eccentric sleeve is provided with an annular groove, and the bottom of the outer wall of the eccentric sleeve is provided with a retaining ring.

[0009] Preferably, the output shaft of the motor is connected to the keyway via a connecting key, the eccentric sleeve is keyed to the output shaft, the inner wall of the bearing cavity abuts against the outer ring of the bearing, the outer wall of the eccentric sleeve abuts against the inner ring of the bearing, the bottom of the outer ring of the bearing abuts against the first retaining ring, the inner ring of the bearing abuts against the second retaining ring, a first shaft retaining ring is embedded in the first annular groove, the bottom of the first shaft retaining ring abuts against the inner and outer rings of the bearing, a second shaft retaining ring is embedded in the annular groove, and the bottom of the second shaft retaining ring abuts against and presses against the top of the first shaft retaining ring.

[0010] Preferably, the top of the eccentric sleeve also includes a locking clamping washer, which is detachably locked to the upper end of the output shaft by screws.

[0011] Preferably, the top of the bearing sleeve also includes a threaded protective cover.

[0012] Preferably, the lower part of the barrel wall of the elastic barrel sleeve is provided with wave-shaped folds, which can absorb the expansion and contraction of the swing disk when it swings up and down.

[0013] Preferably, the elastic barrel sleeve is made of silicone rubber material, which has elasticity and a certain tension.

[0014] The present invention has the following beneficial effects:

[0015] When the motor rotates, the eccentric sleeve, due to the connecting key, becomes integrated with the motor output shaft and rotates synchronously. If the end face of the swing disk is not connected to the lower end face of the elastic barrel sleeve, the swing disk and the motor output shaft will rotate together. Now, the lower end face of the elastic barrel sleeve is fixed to the end face of the swing disk. Because the elastic barrel sleeve is made of silicone rubber, it has elasticity and a certain tension. After the swing disk deflects at a small angle, it stops the rotation of the swing disk. Moreover, the overall structure of this invention is simple and ingenious, and the selection of components, connection methods, and overall working principle are reasonable and clear. It can realize the circular oscillation of the swing disk and has application and promotion value in the material mixing industry. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-4 This invention provides a circular oscillation mechanism design, including a motor 1 and an oscillating disk 2. An eccentric sleeve 3 is fitted onto the end of the output shaft 11 of the motor 1. The eccentric sleeve 3 is assembled into the bearing cavity of the oscillating disk 2 via a bearing 4. An elastic barrel-shaped sleeve 5 is detachably locked to the circumference of the oscillating disk 2 by screws. A housing 6 is detachably locked to the upper circumference of the elastic barrel-shaped sleeve 5 by screws. The lower end of the housing 6 is detachably locked to the upper end face of the motor 1 by screws. An eccentric angle exists between the inner hole axis of the eccentric sleeve 3 and the axis of the output shaft 11 of the motor 1. The upper end face of the eccentric sleeve 3 is set with a wedge-shaped structure, with the angle between the wedge-shaped surface and the horizontal plane, and the eccentric angle, both being 3-5°, specifically set to 3°. This special design of the eccentric sleeve 3, through the small-angle eccentricity of the inner hole and the outer surface (i.e., the wedge-shaped structure of the upper end face of the eccentric sleeve 3), enables the oscillation of the oscillating disk 2. By adjusting the value of the eccentric angle, the amplitude of the oscillation of the oscillating disk 2 can be changed.

[0024] The oscillating disk 2 includes a bearing sleeve 21 and an oscillating disk 22. The outer wall of the bearing sleeve 21 is integrally formed with the oscillating disk 22, and the oscillating disk 22 is set at an inclined angle. The bearing sleeve 21 has a bearing cavity inside, and a retaining ring 41 is provided at the bottom of the bearing cavity. An annular groove 42 is also provided at the upper part of the bearing cavity.

[0025] The bottom of the eccentric sleeve 3 is provided with a keyway groove 31, the upper part of the outer wall of the eccentric sleeve 3 is provided with an annular groove 32, and the bottom of the outer wall of the eccentric sleeve 3 is provided with a stop ring 33.

[0026] The output shaft 11 of motor 1 is connected to keyway 31 via key 12. Eccentric sleeve 3 is keyed to output shaft 11. The inner wall of bearing cavity abuts against outer ring of bearing 4. The outer wall of eccentric sleeve 3 abuts against inner ring of bearing 4. The bottom of outer ring of bearing 4 abuts against first retaining ring 41. Inner ring of bearing 4 abuts against second retaining ring 33. Shaft retaining ring 43 is embedded in annular groove 42. The bottom of shaft retaining ring 43 abuts against inner and outer rings of bearing 4. Shaft retaining ring 34 is embedded in annular groove. The bottom of shaft retaining ring 34 abuts against and presses against top of shaft retaining ring 43.

[0027] The top of the eccentric sleeve 3 also includes a locking clamping washer 7, which is removably locked to the upper end of the output shaft 11 by screws.

[0028] The top of the bearing sleeve 21 also includes a threaded protective cover 8.

[0029] The lower part of the barrel wall of the elastic barrel sleeve 5 is provided with wave-shaped wrinkles 51. The elastic barrel sleeve 5 is made of silicone rubber material, which has elasticity and a certain tension. The silicone rubber elastomer material serves two purposes: firstly, it prevents the rotation of the swing disk 2 after a small deflection angle; secondly, the wave-shaped wrinkles 51 on the barrel wall can absorb the expansion and contraction of the swing disk 2 when it swings up and down.

[0030] Embodiments of the present invention also include the following assembly process:

[0031] (1) As Figure 1 As shown, the motor 1 is assembled into place using bearing 4, wave spring washer, washer, locking washer, locking nut, and screw.

[0032] (2) Figure 4As shown, the connecting key 12 is embedded in the keyway of the output shaft 11 of the motor 1; the bearing 4 is installed in the bearing cavity of the swing disk 2 and fixed with a shaft retaining ring; the eccentric sleeve 3 is pressed into the inner ring of the bearing 4 of the swing disk 2 and fixed with a clamping washer 7, a shaft retaining ring 43, and a shaft retaining ring 34. At this time, the swing disk 2, the eccentric sleeve 3, and the bearing 4 are assembled into one unit; the upper end of the output shaft 11 of the motor 1 is inserted into the inner hole of the eccentric sleeve 3, and the connecting key 12 is embedded in the keyway groove 31 at the end of the eccentric sleeve 3. Then, the clamping washer 7 is used to axially fix the eccentric sleeve 3 on the output shaft 11 of the motor 1, and the protective cover 8 is assembled onto the swing disk 2 (threaded engagement).

[0033] (3) Install the housing 6 onto the end face of the motor 1 with corresponding screws (multiple); connect one end face of the elastic barrel sleeve 5 to the end face of the swing disk 2 with corresponding screws (multiple), and connect the other end face to the end face of the housing 6 with corresponding screws (multiple).

[0034] Embodiments of the present invention also include the following motion process:

[0035] When motor 1 rotates, the eccentric sleeve 3, due to the connection key 12, becomes integrated with the output shaft 11 of motor 1 and rotates synchronously. If the end face of the swing disk 2 is not connected to the lower end face of the elastic barrel sleeve 5, the swing disk 2 and the output shaft 11 of motor 1 will rotate together. Now, the lower end face of the elastic barrel sleeve 5 is fixed to the end face of the swing disk 2. Because the elastic barrel sleeve 5 is made of silicone rubber, it has elasticity and a certain tension. After the swing disk 2 deflects at a small angle, it prevents the rotation of the swing disk 2. Under the action of the eccentric sleeve 3 and the output shaft 11 of motor 1, the end face A of the swing disk 2 is forcibly pushed to swing up and down. Figure 1 Point A moves up and down with the same angular velocity as the output shaft 11 of motor 1 (e.g.) Figure 2 After rotating 180°, it swings to the lowest point (the process is gradual); at the same time, the highest point moves in a circle with the output shaft 11 of motor 1, realizing the design of a circular swing mechanism. The circular points with the same radius as point A all swing up and down, but with different timing, and the changing angular velocity is the same as above.

[0036] During the process, the elastic barrel sleeve 5 prevents the swing disk 2 from rotating with the output shaft 11 of the motor 1, but the eccentric sleeve 3 rotates with the output shaft 11 of the motor 1. The outer circle of the eccentric sleeve 3 (i.e., the upper end face of the eccentric sleeve 3 is set with a wedge structure), the axis of the inner hole, and the axis of the output shaft 11 of the motor 1 have an eccentric angle, which causes the swing disk connected to the outer ring of the bearing 4 to swing up and down (axially).

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
