Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Please refer to fig. 1-2, which are a reciprocating swing mechanism for dispensing application with a fixed width, and the reciprocating swing mechanism comprises a main gear 2 driven by a servo motor 1 to rotate, wherein both sides of the main gear 2 are engaged with auxiliary gears 3, the servo motor 1 drives the main gear 2 to rotate, and the main gear 2 thereby drives the auxiliary gears 3 to rotate, so that the auxiliary gears 3 keep the same direction to rotate. Preferably, in the present embodiment, two of the meshing-gear sub-wheels 3 are provided on the upper side and the lower side of the meshing-gear main wheel 2, respectively.

Each meshing gear auxiliary wheel 3 is fixedly connected with a gear shaft 4, each gear shaft 4 is detachably provided with a linkage swing rod 5, the two linkage swing rods 5 are connected through a swing rod connecting plate 6, and each linkage swing rod 5 is rotatably connected with the swing rod connecting plate 6. Because two meshing gear auxiliary wheels 3 are arranged in the vertical direction, namely, the swing rod connecting plate 6 is in a vertical state, and the two linkage swing rods 5 are respectively connected to the upper end and the lower end of the swing rod connecting plate 6. And the swing rod connecting plate 6 is detachably connected with an external dispensing valve body 7.
