The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figures 1-3 As shown, in one embodiment of the mixing mechanism, the mixing mechanism includes a main body 1, a driving component 2, a guide component 3, and a mixing component 4. The driving component 2, the guide component 3, and the mixing component 4 are all mounted on the main body 1. The driving end of the driving component 2 is connected to the mixing component 4 and is used to drive the mixing component 4 to move along a first direction. The extending direction of the guide component 3 is parallel to the first direction. The mixing component 4 includes a sliding seat 41, a support component 42, a first bearing 46, and a second bearing 47. The sliding seat 41 is connected to the driving end of the driving component 2. The support component 42 is mounted on the sliding seat 41 and is used to support the reaction cup 5. The first bearing 46 passes through the sliding seat 41 and is engaged with the guide component 3 so that it can rotate during the movement of the mixing component 4 along the first direction. The second bearing 47 is eccentrically mounted on the first bearing 46 and connected to the support component 42 so that it can drive the support component 42 to shake during the rotation of the first bearing 46.

[0028] In this embodiment, by engaging the guide member 3 with the first bearing 46, the first bearing 46 can rotate during the process of the driving component 2 driving the mixing component 4 to move along the first direction. The rotation of the first bearing 46 can drive the second bearing 47, which is eccentrically connected to the first bearing 46, to make a circular motion relative to the first bearing 46. This can shake the support member 42, thereby achieving the technical effect of mixing the reaction cup 5 on the support member 42. It only requires a single power source and has a simple structure, solving the technical problems of high cost and complex structure of existing mobile mixing mechanisms that use two sets of power sources.

[0029] Specifically, the driving assembly 2 can be in various structural forms, and the driving force capable of providing linear motion can be provided, for example, can be a cylinder, an oil cylinder, a linear motor, etc., and can also be a combination of a motor and a transmission belt, a chain, etc. The guide 3 can be in a plate-shaped structure. It can be understood that the guide 3 is a rack or a structure having a rack with linearly arranged sawteeth. The part of the first bearing 46 engaged with the guide 3 can be a gear, that is, can be provided with teeth on the circumference, or can be provided with teeth only on part of the circumference.

[0030] In an embodiment of the mixing mechanism, the guide 3 is further provided with a guide portion 31 extending in the first direction and used for guiding the movement of the sliding seat 41.

[0031] In this embodiment, specifically, the guide portion 31 can be a sliding rail type structure provided on the guide 3, and can also be a sliding groove type structure provided on the guide 3. By providing the guide portion 31, the movement accuracy of the sliding seat 41 can be improved, and deviation can be avoided. By providing the guide portion 31, the first bearing 46 and the guide 3 can be closely engaged, and engagement failure can be avoided.

[0032] In an embodiment of the mixing mechanism, the sliding seat 41 is further provided with a protruding portion 411 on one side opposite to the support 42. The support 42 is further provided with a first protrusion 422 and a second protrusion 423 arranged at intervals. The first protrusion 422 and the second protrusion 423 are respectively located on two sides of the protruding portion 411, so as to respectively abut against the protruding portion 411 during the shaking of the support 42.

[0033] In combination with the foregoing embodiments, it can be understood that the second bearing 47 arranged eccentrically is also a reciprocating motion relative to the circumferential motion of the first bearing 46. Thus, by providing the protruding portion 411 on the sliding seat 41 and the first protrusion 422 and the second protrusion 423 arranged at intervals on the support 42, the first protrusion 422 or the second protrusion 423 can abut against the protruding portion 411 during the circumferential motion of the support 42 relative to the sliding seat 41, and can cooperate to limit the position.

[0034] Specifically, the protruding portion 411 can be a block-shaped or plate-shaped structure.

[0035] In an embodiment of the mixing mechanism, the side wall of the support 42 is provided with an extension portion 421. The first protrusion 422 and the second protrusion 423 are arranged on one side of the extension portion 421 opposite to the sliding seat 41. By providing the extension portion 421, the extension portion 421 can be conveniently extended to the position of the protruding portion 411. Thus, the freedom degree of the position of the protruding portion 411 is improved, and the protruding portion 411 can be arranged outside the movement range of the support 42, so as to avoid interfering with the movement of the support 42.

[0036] Specifically, in combination with the foregoing embodiments, the extension 421 can be in the form of a block or a plate, and the first protrusion 422 and the second protrusion 423 can be in the form of a rod or a shaft. Preferably, the extension direction of the extension 421 is parallel to a horizontal plane. The extension direction of the first protrusion 422 or the second protrusion 423 is perpendicular to the extension direction of the extension 421.

[0037] In an embodiment of the mixing mechanism, two grooves are formed on the side of the support 42 facing away from the sliding seat 41, the two grooves are spaced apart, and the second bearing 47 is arranged between the two grooves at the connection of the support 42.

[0038] In this embodiment, it can be understood that the groove bottom can be used to support the reaction cup 5, and the sidewall of the groove can be used to limit and block the reaction cup 5. By arranging the second bearing 47 between the two grooves, the movement amplitudes of the reaction cups 5 on both sides of the second bearing 47 are substantially the same during the circular motion, and the mixing degree is substantially the same, thereby avoiding the situation that one is mixed and the other is not mixed.

[0039] In an embodiment of the mixing mechanism, a first through hole 412 is formed on the sliding seat 41 to allow the first bearing 46 to pass through, and the mixing assembly 4 further comprises a first bearing 46 support that is at least partially accommodated in the first through hole 412 and connected with the sliding seat 41, and the first bearing 46 support is sleeved on the first bearing 46.

[0041] In an embodiment of the mixing mechanism, the mixing assembly 4 further comprises a second bearing 47 support and a third bearing 48, the second bearing 47 support is sleeved on the first protrusion 422, and the third bearing 48 is sleeved on the second protrusion 423.

[0042] In this embodiment, by arranging the second bearing 47 support and the third bearing 48, the collision between the first protrusion 422 and the second protrusion 423 and the protruding portion 411 can be reduced, thereby prolonging the service life of the first protrusion 422 and the second protrusion 423, and the second bearing 47 support and the third bearing 48 can also function as rolling on the protruding portion 411, thereby making the circular motion smoother.

[0043] In an embodiment of the mixing mechanism, the end of the first bearing 46 away from the second bearing 47 is sleeved on the annular member 45, and the outer wall of the annular member 45 is provided with a toothed portion to be able to engage with the guide 3.

[0044] In combination with the foregoing embodiments, the annular member 45 in the present embodiment can be a gear, which is arranged to mesh with the teeth on the side wall of the guide member 3, and the meshing connection mode can enable the mixing assembly 4 to rotate during the overall linear movement, thereby achieving the effect of mixing the reaction cup 5 while moving.

[0045] In an embodiment of the mixing mechanism, the support member 42 is provided with a second through hole 424 for the second shaft 44 to pass through, and the mixing mechanism further comprises a fourth bearing 49, which is sleeved on the second shaft 44 and accommodated in the second through hole 424.

[0046] In the present embodiment, the fourth bearing 49 is arranged in the same way as in the foregoing embodiments, which can reduce the friction of the second shaft 44, thereby reducing the wear of the second shaft 44, prolonging the service life of the second shaft 44, and reducing the energy consumption.
