[0026] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the invention. After reading this invention, any modifications of the invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0027] A fully automatic solution dispensing and sealing machine, such as Figure 1-6 As shown, the machine includes a frame 1, a turntable 2, a turntable drive motor, a bottle-rubbing mechanism 3, a flame-spraying mechanism 5, and a filling system 6. The turntable drive motor, the flame-spraying mechanism 5, and the filling system 6 are fixed relative to the frame 1. The turntable 2 is mounted on the frame 1, and the turntable 2 is connected to the drive shaft of the turntable drive motor.

[0028] The turntable 2 is provided with a placement hole 21, and the placement hole 21 is provided with a positioning part 211. The positioning part 211 includes a large opening end 213 and a small opening end 212. The opening distance of the positioning part 211 gradually decreases from the opening distance of the large opening end 213 to the opening distance of the small opening end 212. The small opening end 212 is located on the side of the nozzle of the flame gun 51 near the flame spraying mechanism 5.

[0029] The bottle-rubbing mechanism 3 is used to squeeze the ampoule 7 towards the small opening end 212 of the positioning part 211, and apply a pre-tightening force to the ampoule 7, while driving the ampoule 7 to rotate.

[0030] like Figure 2 and 3 As shown, the bottle-rubbing mechanism 3 includes a driving wheel 31, a driven wheel 32, and a compression rotating belt 33. The compression rotating belt 33 is a rubber track. The driving wheel 31 and the driven wheel 32 are mounted on the frame 1 and are connected by transmission through the compression rotating belt 33. The compression rotating belt 33 is used to squeeze the ampoule 7 towards the small opening end 212 of the positioning part 211 under the drive of the driving wheel 31, and to apply a pre-tightening force to the ampoule 7. At the same time, the compression rotating belt 33 drives the ampoule 7 to rotate.

[0031] like Figure 1 , 3As shown, the flame gun 51 is located at the center of the turntable 2, with the smaller end of its opening pointing towards the inner side of the turntable 2 and the larger end pointing towards the outer side of the turntable 2. The compression rotating belt 33 compresses the ampoule 7 from the outer side of the turntable 2 towards the center of the turntable 2. In another embodiment, the flame gun 51 is located on the outer side of the turntable 2, with the smaller end pointing towards the outer side of the turntable 2 and the larger end pointing towards the inner side of the turntable 2. The compression rotating belt 33 compresses the ampoule 7 from the center of the turntable 2 towards the outer side of the turntable 2.

[0032] When sealing is required, the turntable 2 rotates, moving the ampoule 7 to be sealed to the sealing station. At this time, the ampoule 7 is positioned by the interaction of the positioning part 211 of the placement hole 21 and the squeezing rotating belt 33. Simultaneously, the outermost end of the positioned ampoule 7 extends into the area enclosed by the tangents on both sides of the driving wheel 31 and the driven wheel 32. Figure 3 As shown, after positioning, the ampoule 7 squeezes the adjacent compression rotating belt 33 outward, making the compression rotating belt 33 V-shaped. On the one hand, this makes the positioning of the ampoule 7 more stable, and on the other hand, it increases the friction force between the ampoule 7 and the compression rotating belt 33. This friction force is much greater than the friction force between the ampoule 7 and the positioning part 211. Driven by the drive wheel 31, the compression rotating belt 33 can drive the ampoule 7 to rotate through the friction force.

[0033] Once the sealing process is complete, the turntable 2 rotates, moving the sealed ampoule 7 so that the ampoule 7 separates from the compression rotating belt 33.

[0034] like Figure 4 and 5 As shown, in another embodiment of the present invention, a straightening mechanism 4 is provided, which is used to straighten the ampoule 7 during filling.

[0035] like Figure 4 and 5 As shown, the straightening mechanism 4 includes a straightening arm 41, a straightening bracket 42, and a pre-tensioning spring. The straightening bracket 42 is mounted on the frame 1. The straightening arm 41 is rotatably mounted on the straightening bracket 42 via a straightening shaft 421. One end of the pre-tensioning spring is connected to the straightening bracket 42, and the other end is connected to the straightening arm 41. The straightening arm 41 is used to press the ampoule 7 towards the small opening end 212 of the positioning part 211 under the action of the pre-tensioning spring.

[0036] The straightening arm 41 is provided with a pre-tension spring mounting post 412 and a rotating hole 413. The straightening bracket 42 is provided with a pre-tension spring mounting post 422. The straightening shaft 421 passes through the rotating hole 413 and is rotatably connected to the rotating hole 413. One end of the pre-tension spring is mounted on the pre-tension spring mounting post 412, and the other end is mounted on the pre-tension spring mounting post 422.

[0037] The straightening arm 41 is provided with a straightening slot 411, which is an arc-shaped slot. The arc-shaped slot cooperates with the small opening end 212 of the positioning part 211 to straighten and hold the ampoule 7.

[0038] When filling is required, the turntable 2 rotates, moving the ampoule 7 to the filling position. During the process of moving the ampoule 7 to the filling position, the turntable 2 drives the ampoule 7 to contact the arc-shaped latch first, pushing the straightening shaft 421 to rotate. The pre-tension spring 1 is stretched and deformed, generating elastic force. Under the action of elastic force, the straightening arm 41 squeezes the ampoule 7 towards the small opening end 212 through the arc-shaped latch until the ampoule 7 can no longer move towards the small opening end 212. When the ampoule 7 moves to the filling position, the turntable 2 stops rotating. At this time, the ampoule 7 is fixed between the straightening latch 411 and the positioning part 211.

[0039] After filling is completed, the turntable 2 rotates, moving the filled ampoules 7 to the next station. During the movement of the ampoules 7 by the turntable 2, the ampoules 7 push the straightening latch 411 to rotate. The straightening latch 411 pushes the straightening arm 41 to rotate around the straightening shaft 421, causing the pre-tension spring to stretch until the ampoule 7 disengages from the straightening latch 411. At this point, the pre-tension spring returns to its original position, causing the straightening arm 41 to rotate back to its initial position.

[0040] In another embodiment, the straightening mechanism 4 includes a telescopic rod, a second straightening bracket, and a second pre-tensioning spring. The second straightening bracket is provided with a sliding groove, the telescopic rod is installed in the sliding groove, and the telescopic rod is slidably connected along the sliding groove. One end of the second pre-tensioning spring is installed on the second straightening bracket, and the other end is installed on the telescopic rod. An arc-shaped latch is provided on the free end of the telescopic rod.

[0041] When filling is required, the turntable 2 rotates, moving the ampoule 7 to the filling position. During the process of moving the ampoule 7 to the filling position, the turntable 2 causes the ampoule 7 to first contact the arc-shaped latch 2, pushing the telescopic rod to move outward. The pre-tension spring 2 is stretched and deformed, generating elastic force. Under the action of elastic force, the telescopic rod squeezes the ampoule 7 towards the small opening end 212 through the arc-shaped latch 2 until the ampoule 7 can no longer move towards the small opening end 212. When the ampoule 7 moves to the filling position, the turntable 2 stops rotating. At this time, the ampoule 7 is fixed between the arc-shaped latch 2 and the positioning part 211.

[0042] After filling is complete, turntable 2 rotates, moving the filled ampoules 7 to the next station. As turntable 2 moves the ampoules 7, they push the arc-shaped latch 2, which in turn pushes the telescopic rod outwards. This causes the pre-tension spring 1 to stretch until the ampoule 7 disengages from the arc-shaped latch 2. At this point, the pre-tension spring 2 resets, causing the telescopic rod to move inwards, returning it to its initial position.

[0043] In another embodiment, such as Figure 2 and 6 As shown, the turntable 2 includes a first turntable 22, a second turntable 23, and a third turntable arranged sequentially from top to bottom. The placement hole 21 passes through the first turntable 22 and the second turntable 23. A gap is provided between the first turntable 22 and the second turntable 23. The squeezing rotating belt 33 squeezes the ampoule 7 towards the small opening end 212 of the positioning part 211 through the gap between the turntables. At the same time, the squeezing rotating belt 33 drives the ampoule 7 to rotate. The straightening mechanism 4 straightens the ampoule 7 through the gap between the turntables.

[0044] In another embodiment, such as Figure 1 As shown, the system includes a filling system 6, which is driven by three lead screw motors to move the lead screws in the X, Y, and Z directions. The filling system 6 includes a column 61, a horizontal bar 62, a vertical bar 63, an injection needle mounting head 64, and a medicine bag. The column 61 is mounted on a frame 1. A first lead screw drive motor, a first lead screw, and a first lead screw nut are disposed within the column 61. The first lead screw drive motor is connected to the first lead screw, and the first lead screw nut is mounted on the first lead screw. The horizontal bar 62 is slidably mounted on the column 61 via a groove, and is fixedly connected to the first lead screw nut. A second lead screw drive motor, a second lead screw, and a second lead screw nut are disposed within the horizontal bar 62. The second lead screw drive motor is connected to the second lead screw, and the second lead screw nut is mounted on the second lead screw. The vertical bar 63 is slidably mounted on the horizontal bar 62 via a groove, and is fixedly connected to the second lead screw nut. The vertical rod 63 houses a third lead screw drive motor, a third lead screw, and a third lead screw nut. The third lead screw drive motor is connected to the third lead screw in a transmission manner. The third lead screw nut is mounted on the third lead screw. The injection needle mounting head 64 is slidably mounted on the vertical rod 63 via a sliding groove, and the injection needle mounting head 64 is fixedly connected to the third lead screw nut. The medicine bag is mounted on the frame 1, and the medicine bag is connected to the injection needle mounting head 64 via a pipe.

[0045] In another embodiment, such as Figure 1As shown, the flame-spraying mechanism 5 includes a flame gun 51, a nozzle mounting rod 52, and a fuel tank. The nozzle mounting rod 52 is mounted on the frame 1, and the flame gun 51 is mounted on the nozzle mounting rod 52. The flame gun 51 and the fuel tank are connected by a fuel pipe. The frame 1 is provided with a baffle plate 53, which is located in the direction of the flame spray from the nozzle of the flame gun 51.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
