As shown in fig. 1 and 2, a variable speed bag knocking mechanism 1 includes a rotating portion 10; a telescopic member 20, one end of the telescopic member 20 is eccentrically and fixedly connected with the rotating part 10, and the axis A2 of the telescopic member 20 is parallel to the rotating shaft A1 of the rotating part 10; telescopic member 20 is itself rotatable about axis a 2; a swinging part 30, one end of the swinging part 30 is provided with a driving part 31, the other end of the telescopic component 10 is connected to the driving part 31 in a sliding way, and the sliding axis A3 is vertical to the axis A2 of the telescopic component 20; the other end of the swing portion 30 is a working end 32; the oscillating portion 30 is capable of oscillating movement within a range about an axis of rotation a4 between the drive portion 31 and the working end 32. Through the arrangement, the rotary motion of the motor can be converted into the swinging motion of the swinging part, the speed is variable in the swinging process, and the effect of knocking the soft bag by hands can be simulated.

It should be noted that the rotation axis a4 of the swinging unit 30 may be any direction in a plane perpendicular to the rotation axis a1 of the rotating unit 10, which substantially converts the rotating motion of the telescopic member into swinging motion in a certain direction. Preferably, the rotation axis a4 is a vertical direction or a horizontal direction, and when the rotation axis a4 is a vertical direction, the swing portion swings in a horizontal plane; when the rotation axis a4 is horizontal, the swing portion 30 swings in a vertical plane.

The rotating portion 10 includes a driving source (not shown in the drawings), and a rotating member 11 drivingly connected to the driving source. The power of the drive source is converted into the rotational motion of the rotating member 11.

It is understood that the driving source may be an electric, hydraulic, pneumatic or internal combustion engine, etc. and transmits power to the rotating member 11 to drive the rotating member 11 to rotate around the rotation axis a 1; preferably, the driving source is an electric motor, and the electric motor directly or indirectly drives the rotating member 11 to rotate. The motor directly drives the rotating part means that the output shaft of the motor is directly and fixedly connected with the rotating part 11; the motor indirectly drives the rotating member means that the motor transmits power to the rotating member 11 through a speed reduction mechanism or a transmission mechanism.

The rotating member 11 may be a disk as shown in fig. 1, or may be a rod or other shape as long as it is disposed offset from the rotation axis a1 so that the retractable member 20 can be fixedly coupled to the rotating member 11 eccentrically.

The telescopic component 20, the telescopic component 20 can realize the telescopic motion in the direction of the axis a2, and can realize the relative rotation by itself, the realization mode includes many, preferably, in this embodiment, the telescopic component 20 includes a cylinder part 21 and a telescopic rod 22 connected in the cylinder part 21 in a sliding way, the telescopic rod 22 can not perform the telescopic motion by itself, and the telescopic effect can be realized by cooperating with the cylinder part 21; the barrel part 21 or the telescopic rod 22 is in sliding connection with the driving part 31 through the connecting seat 23 to realize telescopic motion between the barrel part and the driving part; the telescopic part 20 can rotate relatively, and the specific implementation mode comprises: (1) the barrel part 21 is connected with the telescopic rod 22 in a relatively rotatable way; (2) the barrel part 21 or the telescopic rod 22 is rotatably connected with the connecting seat 23; (3) the barrel 21 and the telescopic rod 22 are connected in a relatively rotatable manner, and the barrel 21 or the telescopic rod 22 is connected in a rotatable manner with the connecting seat 23.

The driving portion 31 of the swing portion 30 is a smooth rod, and the mounting base 23 is slidably coupled to the driving portion 31 by a linear bearing or a slide bearing.

The variable speed bag knocking mechanism 1 further comprises a support 40, wherein the support 40 is used for supporting the swinging part 30, so that the swinging part 30 swings in a certain range. In this embodiment, as shown in fig. 1 and 2, the bracket 40 is provided in a "U" shape, and the swing portion 30 is rotatably connected to the U-shaped end portion of the bracket 40. In order to reduce the size of the variable speed bag knocking mechanism 1, the rotating part 10 and the telescopic part 20 are both arranged inside the U-shaped bracket.

The contact portion of the working end 32 of the oscillating portion 30 is smoothly arcuate, it being understood that the contact portion does not have a sharp protruding shape to prevent scratching of the surface of the soft bag, and therefore the contact portion may be smoothly cylindrical or only the contact portion may be arcuate.

The distance between the rotation axis A4 of the swing part 30 and the driving part 31 is smaller than the distance between the rotation axis A4 and the working end 32, and according to the lever principle, the arrangement enables the small swing range of the driving part to realize the large swing range of the working end 32, and simultaneously doubles the movement speed of the working end 32, and increases the knocking force of the working end on the soft bag. The distance between the rotation axis A4 and the driving part 31 is the distance between the rotation axis A4 and the sliding axis A3; the distance between the axis of rotation a4 and the working end 32 refers to the distance between the axis of rotation a4 and the end of the working end 32.

The rotation axis a4 of the swing portion 30 is perpendicular to the rotation axis of the rotating portion 10 and may intersect or may not intersect with each other, and the difference is that the swing range and the position of the maximum swing speed of the swing portion 30 are changed. In the present embodiment, the rotation axis a4 of the swing portion 30 intersects perpendicularly with the rotation axis of the rotating portion 10, and the movement principle under this condition will be described below.

As shown in fig. 3, the rotating member 11 rotates at a constant angular velocity ω, and the distance between the rotation axis a1 of the rotating member 10 and the axis a2 of the extendable member 20 is r; the telescopic member 20 rotates around the rotation axis a1 at ω r. When the moving object moves to the position shown in fig. 3, the angle between the connecting line and the circle center a1 and the vertical direction is a, the velocity component Vy in the vertical direction is wrsin (a), and the velocity component Vx in the horizontal direction is wrcos (a). Therefore, when a is 0 or 180 degrees, the Vy velocity is 0, and the Vx direction velocity is at most wr; when a is 90 degrees, Vy velocity is wr and Vx direction velocity is 0. When the angle a changes from 0 to 180 degrees, the vertical direction velocity Vy increases from 0 to wr and then decreases to 0; the velocity Vx in the horizontal direction decreases from wr to 0 and increases again to wr. When the rotation axis of the swing part 30 is horizontal and is perpendicular to and intersected with the rotation axis of the rotating part 10, the swing part 30 swings in a vertical plane, and at the moment, the vertical motion of the telescopic component 20 is transmitted to the swing part and is converted into the swing motion of the working end 32 after being amplified by leverage; when the telescopic part rotates clockwise and upwards from the lowest position, the speed of the telescopic part a is gradually increased from 0 to 180 degrees, the speed Vy in the vertical direction is increased from 0 to wr and then is reduced to 0, and the speed Vy is maximum at wr when the speed a is 90 degrees; therefore, the effect of simulating manual knocking of the soft bag can be realized.

In another aspect, this embodiment provides a light inspection machine, including any one of the above-mentioned variable speed bag knocking mechanisms.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
