[0024] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0025] A solution dispensing, sealing, positioning and clamping device, such as Figure 1-6 As shown, it includes a frame 1, a turntable 2, a turntable drive motor, a bottle rubbing mechanism 3 and a flame spraying mechanism 5. The flame spraying mechanism 5 and the turntable drive motor are relatively fixed to the frame 1. The turntable 2 is installed on the frame 1, and the turntable 2 is drivingly connected to the drive shaft of the turntable drive motor.

[0026] The turntable 2 is provided with a placement hole 21, and the placement hole 21 is provided with a positioning portion 211, the positioning portion 211 includes an opening large end 213 and an opening small end 212, and the opening distance of the positioning portion 211 gradually decreases from the opening large end 213 to the opening distance of the opening small end 212, and the opening small end 212 is located at the muzzle side of the flamethrower 51 close to the flamethrower mechanism 5.

[0027] The bottle rubbing mechanism 3 is used to squeeze the ampoule bottle 7 toward the open small end 212 of the positioning portion 211 , apply a pre-tightening force to the ampoule bottle 7 , and drive the ampoule bottle 7 to rotate.

[0028] like Figure 2 and 3 As shown, the bottle rubbing mechanism 3 includes a driving wheel 31, a driven wheel 32, and an extrusion rotating belt 33. The extrusion rotating belt 33 is a rubber track. The driving wheel 31 and the driven wheel 32 are mounted on the frame 1. The driving wheel 31 and the driven wheel 32 are connected by the extrusion rotating belt 33. The extrusion rotating belt 33 is used to squeeze the ampoule bottle 7 toward the open small end 212 of the positioning portion 211 under the drive of the driving wheel 31, and apply a pre-tightening force to the ampoule bottle 7. At the same time, the extrusion rotating belt 33 drives the ampoule bottle 7 to rotate.

[0029] like Figure 1 , 3 As shown, the flame spray gun 51 is located at the center of the turntable 2, the small end of the opening points to the inner side of the turntable 2, and the large end of the opening points to the outer side of the turntable 2, and the extrusion rotating belt 33 squeezes the ampoule bottle 7 from the outer side of the turntable 2 to the center of the turntable 2. In another embodiment, the flame spray gun 51 is located outside the turntable 2, the small end of the opening points to the outer side of the turntable 2, and the large end of the opening points to the inner side of the turntable 2. The extrusion rotating belt 33 squeezes the ampoule bottle 7 from the center of the turntable 2 to the outer side of the turntable 2.

[0030] When sealing is required, the turntable 2 rotates to move the ampoule bottle 7 to be sealed to the sealing station. At this time, the ampoule bottle 7 is positioned by the interaction between the positioning portion 211 of the placement hole 21 and the extrusion rotating belt 33. At the same time, the outermost end of the positioned ampoule bottle 7 extends into the area surrounded by the tangents on both sides of the driving wheel 31 and the driven wheel 32, as shown in FIG. Figure 3 As shown, the positioned ampoule bottle 7 squeezes the adjacent extrusion rotating belt 33 outward, so that the extrusion rotating belt 33 is V-shaped. On the one hand, the positioning of the ampoule bottle 7 is more stable. On the other hand, the friction force 1 between the ampoule bottle 7 and the extrusion rotating belt 33 is increased, so that the friction force 1 is much greater than the friction force 2 between the ampoule bottle 7 and the positioning portion 211. Under the drive of the driving wheel 31, the extrusion rotating belt 33 can drive the ampoule bottle 7 to rotate through the friction force 1.

[0031] When the sealing is completed, the turntable 2 rotates to move the sealed ampoule bottle 7 so that the ampoule bottle 7 is separated from the extrusion rotating belt 33 .

[0032] like Figure 4 and 5 As shown, in another embodiment of the present utility model, a straightening mechanism 4 is provided, and the straightening mechanism 4 is used for straightening the ampoule bottle 7 during filling.

[0033] like Figure 4 and 5 As shown, the righting mechanism 4 includes a righting arm 41, a righting bracket 1 42, and a preload spring 1. The righting bracket 1 42 is mounted on the frame 1. The righting arm 41 is rotatably mounted on the righting bracket 1 42 via a righting shaft 421. One end of the preload spring 1 is connected to the righting bracket 1 42, and the other end is connected to the righting arm 41. The righting arm 41 is used to squeeze the ampoule bottle 7 toward the open small end 212 of the positioning portion 211 under the action of the preload spring 1.

[0034] The said righting arm 41 is provided with a pre-tensioning spring first mounting column 412 and a rotating hole 413, the said righting bracket 42 is provided with a pre-tensioning spring first mounting column 422, the said righting shaft 421 passes through the rotating hole 413, and the righting shaft 421 is rotatably connected with the rotating hole 413. One end of the said pre-tensioning spring first is installed on the pre-tensioning spring first mounting column 412, and the other end is installed on the pre-tensioning spring first mounting column 422.

[0035] The straightening arm 41 is provided with a straightening snap-on 411 , which is an arc-shaped snap-on. The arc-shaped snap-on cooperates with the open small end 212 of the positioning portion 211 to straighten and clamp the ampoule bottle 7 .

[0036] When filling is required, the turntable 2 rotates to move the ampoule bottle 7 to be filled to the filling position. During the process of the ampoule bottle 7 moving to the filling position, the turntable 2 drives the ampoule bottle 7 to contact the arc-shaped bayonet first, and pushes the straightening shaft 421 to rotate. The preloaded spring produces a tensile deformation and generates an elastic force. Under the action of the elastic force, the straightening arm 41 squeezes the ampoule bottle 7 toward the open small end 212 through the arc-shaped bayonet until the ampoule bottle 7 cannot move toward the open small end 212. When the ampoule bottle 7 moves to the filling position, the turntable 2 stops rotating. At this time, the ampoule bottle 7 is fixed between the straightening bayonet 411 and the positioning portion 211.

[0037] When the filling is completed, the turntable 2 rotates to move the filled ampoule 7 to the next station. During the movement of the ampoule 7 driven by the turntable 2, the ampoule 7 pushes the righting clip 411 to rotate, and the righting clip 411 pushes the righting arm 41 to rotate around the righting rotation axis 421, and the preload spring is stretched and deformed until the ampoule 7 is separated from the righting clip 411. At this time, the preload spring is reset, driving the righting arm 41 to rotate, so that the righting arm 41 returns to the initial position.

[0038] In another embodiment, the righting mechanism 4 includes a telescopic rod, a righting bracket two, and a pre-tensioning spring two. The righting bracket two is provided with a slide groove, the telescopic rod is installed in the slide groove, and the telescopic rod is slidably connected along the slide groove. One end of the pre-tensioning spring two is installed on the righting bracket two, and the other end is installed on the telescopic rod. The free end of the telescopic rod is provided with an arc-shaped bayonet two.

[0039] When filling is required, the turntable 2 rotates to move the ampoule bottle 7 to be filled to the filling position. During the process of the ampoule bottle 7 moving to the filling position, the turntable 2 drives the ampoule bottle 7 to contact the arc-shaped bayonet 2 first, pushing the telescopic rod to move outward, and the preloaded spring 2 produces a tensile deformation to generate an elastic force. Under the action of the elastic force, the telescopic rod squeezes the ampoule bottle 7 toward the open small end 212 through the arc-shaped bayonet 2 until the ampoule bottle 7 cannot move toward the open small end 212. When the ampoule bottle 7 moves to the filling position, the turntable 2 stops rotating. At this time, the ampoule bottle 7 is fixed between the arc-shaped bayonet 2 and the positioning portion 211.

[0040] When the filling is completed, the turntable 2 rotates to move the filled ampoule 7 to the next station. During the movement of the ampoule 7 driven by the turntable 2, the ampoule 7 pushes the arc-shaped bayonet 2 to move, and the arc-shaped bayonet 2 pushes the telescopic rod to move outward, and the preload spring 1 produces a tensile deformation until the ampoule 7 is separated from the arc-shaped bayonet 2. At this time, the preload spring 2 is reset, driving the telescopic rod to move inward, so that the telescopic rod returns to the initial position.

[0041] In another embodiment, if Figure 2 and 6As shown, the turntable 2 includes a first turntable 22, a second turntable 23, and a third turntable arranged in sequence from top to bottom, the placement hole 21 passes through the first turntable 22 and the second turntable 23, and the first turntable 22 and the second turntable 23 are provided with a turntable gap, and the extrusion rotating belt 33 squeezes the ampoule bottle 7 toward the open small end 212 of the positioning portion 211 through the turntable gap, and the extrusion rotating belt 33 drives the ampoule bottle 7 to rotate. The straightening mechanism 4 straightens the ampoule bottle 7 through the turntable gap.

[0042] In another embodiment, if Figure 1 As shown, it includes a filling system 6, and the filling system 6 is driven by three screw drive motors to drive the screws to realize movement in three directions of XYZ. The filling system 6 includes a column 61, a cross bar 62, a vertical rod 63, an injection needle mounting head 64 and a medicine bag. The column 61 is installed on the frame 1, and the column 61 is provided with a first screw drive motor, a first screw, and a first screw nut. The first screw drive motor is connected to the first screw by transmission, and the first screw nut is installed on the first screw. The cross bar 62 is slidably installed on the column 61 through a slide groove, and the cross bar 62 is fixedly connected to the first screw nut. The cross bar 62 is provided with a second screw drive motor, a second screw, and a second screw nut.
