DETAILED DESCRIPTION

[0062] The application will be further described below in conjunction with the drawings.

[0063] The specific embodiments are only an explanation of the application, and are not a limitation of the application. Those skilled in the art can make modifications to the embodiments without creative contribution, as long as the modifications are within the scope of the claims of the application.

[0064] Embodiment

[0065] An infusion bag intelligent water needle dispensing machine, comprising a rack, a bottle box pushing and medicine feeding mechanism, an ampoule bottle turntable mechanism, a liquid extraction and injection mechanism, and a liquid discharge mechanism.

[0066] As shown in Figures 1 to 5 , the bottle box pushing and medicine feeding mechanism comprises a bottle box 1, a containing sliding groove 11, and an elastic pushing part. The elastic pushing part pushes the ampoule bottle 0 in the containing sliding groove 11 forward under the elastic action of an upper bottle spring.

[0067] As shown in Figures 2 to 5 , one end of the containing sliding groove 11 in the length direction is an upper bottle position 111, which extends along the length direction of the bottle box 1. The containing sliding groove 11 is arranged on the bottle box 1, and is arranged on the upper surface of the bottle box 1 for the convenience of placing the ampoule bottle 0. The containing sliding groove 11 extends upward to form an upper bottle opening 115 for the ampoule bottle 0 to enter and exit the containing sliding groove 11. The ampoule bottle 0 can be placed downward from the position of the upper bottle opening 115. In the design process, the containing sliding groove 11 is designed to contain one ampoule bottle 0 in the width direction, but two or more ampoule bottles 0 can be arranged in the width direction, or one ampoule bottle 0 can be arranged between adjacent ampoule bottles 0 in the width direction, which all belong to the concept range and the patent protection range.

[0068] As Figures 1 to 5 shown, the elastic pushing part includes a pushing plate 121 and an upper bottle spring, the pushing plate 121 abuts against the side of the ampoule 0, one end of the upper bottle spring in the length direction is connected with the bottle box 1, the other end of the upper bottle spring in the length direction is connected with the pushing plate 121, and the upper bottle spring drives the pushing plate 121 to move in the length direction of the containing sliding groove 11 to the upper bottle position 111.

[0069] As Figure 2 , Figure 3 and Figure 4 shown, the upper bottle spring is arranged in a manner that the elastic pushing part further includes a guide ring 123, both ends of the guide ring 123 in the length direction are fixed with the bottle box 1, the pushing plate 121 is provided with a guide hole 124 matched with the guide ring 123, the upper bottle spring is sleeved on the guide ring 123, and the guide ring 123 is a structure in a transverse U shape. The guide ring 123 plays a guiding role on the pushing plate 121. It is also known that the upper bottle spring is not shown in the embodiment, because the upper bottle spring can drive the pushing plate 121 to move in a stretching manner within the technical concept, for example, one end of the upper bottle spring is connected near the upper bottle position 111, and the other end of the upper bottle spring is connected with the pushing plate 121. Similarly, the pushing plate 121 can also be driven to move in a pushing manner, that is, in the present example, a limiting block 125 is arranged in the bottle box 1, the guide ring 123 includes an upper horizontal section 126, a lower horizontal section 127 and an arc transition section 128, one end of the lower horizontal section 127 is connected with the limiting block 125, the other end of the lower horizontal section 127 is connected with one end of the arc transition section 128, the other end of the arc transition section 128 is connected with one end of the upper horizontal section 126, the other end of the upper horizontal section 126 is connected with one end of the upper bottle position 111 of the bottle box 1, one end of the upper bottle spring abuts against the limiting block 125, and the other end of the upper bottle spring abuts against the pushing block. A guide rail 129 is arranged in the bottle box 1 along the length direction of the containing sliding groove 11, the pushing plate 121 is slidingly connected with the guide rail 129, the friction between the pushing plate 121 and the bottle box 1 is reduced, and the service life of the pushing plate 121 is improved.

[0070] As Figure 2 , Figure 4 and Figure 5 shown, in order to facilitate external pushing of the pushing plate 121, the further structural improvement is that the bottle box 1 is provided with a return channel 112 on the side wall of the containing sliding groove 11, the return channel 112 extends along the length direction of the bottle box 1, the return channel 112 is arranged through the side wall of the bottle box 1, the pushing plate 121 extends outward along the width direction of the return channel 112 to form a return block 113, and at the same time, the side wall of the bottle box 1 in the width direction is recessed to form a return groove 114 for the movement of the return block 113, that is, the operator can drive the pushing plate 121 to move by moving the return block 113 externally.

[0071] When the ampoule 0 needs to be loaded in the bottle box 1, the push plate 121 is pushed backward by the return block 113, the ampoule 0 is placed in the empty slot between the push plate 121 and the containing sliding slot 11, and the bottle loading spring is compressed by the push plate 121. After the placement is completed, the push plate 121 is driven to push the ampoule 0 to move forward under the elastic force of the bottle loading spring, and is in abutment with the side wall of the bottle loading position 111 of the containing sliding slot 11. In the process of loading the ampoule 0 in the bottle box 1, when the ampoule 0 in the bottle loading position 111 is taken out, a space is formed in the containing sliding slot 11. At this time, the push plate 121 pushes the ampoule 0 forward under the elastic force of the compressed bottle loading spring, and pushes the ampoule 0 behind the bottle loading position 111 to the bottle loading position 111, thereby satisfying the one-by-one loading of the ampoule 0 in the bottle box 1.

[0072] As shown in Figures 6 to 9 , the bottle box pushing medicine loading mechanism further comprises a rack 01 and a bottle box 1. The bottle box 1 can be formed by plastic injection molding. The rack 01 is provided with a mounting slot 13. The mounting slot 13 is rectangular. The side wall of the mounting slot 13 in the width direction is in abutment with the side wall of the bottle box 1, so that the mounting slot 13 limits the movement of the bottle box 1 in the width direction by abutting with the side wall of the bottle box 1 in the width direction.

[0073] As shown in Figure 8 and Figure 9 , the mounting slot 13 is provided with a front limiting slot 131 and a rear limiting slot 132. The front limiting slot 131 is rectangular and communicates with the rear limiting slot 132. The front limiting slot 131 is provided downward. A blocking position is formed between the front limiting slot 131 and the mounting slot 13. The bottle box 1 is provided with a limiting clamping plate 141 and a limiting column 142. The limiting clamping plate 141 is provided at one end of the bottle box 1 in the length direction and extends outward. The limiting clamping plate 141 is provided at the bottom of the bottle box 1, and the two sides of the limiting clamping plate 141 in the width direction extend to the two sides of the bottle box 1 in the width direction. An inclined surface 143 is provided on the side of the limiting clamping plate 141 close to the limiting column 142. The limiting column 142 is provided at the bottom of the bottle box 1. The rear limiting slot 132 is provided with two. The rear limiting slot 132 is provided at the two sides of the front limiting slot 131 in the width direction. The cross-sectional shape of the limiting column 142 is circular. The bottom of the limiting column 142 is provided with an inclined surface for reducing the collision between the limiting column 142 and the rear limiting slot 132. The side wall of the rear limiting slot 132 is arc-shaped. The top of the front limiting slot 131 is in abutment with the upper surface of the limiting clamping plate 141, limiting the upward movement of the bottle box 1. The side wall of the front limiting slot 131 is in abutment with the front end of the limiting clamping plate 141, limiting the horizontal movement of the bottle box 1 towards the center of the rack 01. The rear limiting slot 132 cooperates with the limiting column 142 to limit the horizontal movement of the bottle box 1 away from the rack 01.

[0074] As shown in Figure 7As shown, the inner side of the front limiting groove 131 is provided with a sensor 133, and the front end of the bottle box 1 is provided with a detection block made of metal for the sensor 133 to detect. When the sensor 133 detects the detection block, it is determined that the bottle box 1 has been installed in place.

[0075] An ampoule is installed in the bottle box 1. The operator holds the rear end of the bottle box 1, and after the front end of the bottle box 1 enters the installation groove 13, the limiting clamping plate 141 is located directly below the front limiting groove 131. By rotating the bottle box 1 upward, the upper side of the limiting clamping plate 141 abuts against the bottom of the front limiting groove 131. At this time, the limiting column 142 also abuts against the rear limiting groove 132. After being fixed, the front limiting groove 131 restricts the upward movement or rotation of the bottle box 1. The side wall of the bottle box 1 cooperates with the installation groove 13 to restrict the movement or rotation of the bottle box 1 in the width direction. At the same time, the rear limiting groove 132 cooperates with the limiting column 142 to restrict the movement of the bottle box 1 in the horizontal direction away from the rack 01, thereby achieving the effect of quickly fixing the bottle box 1.

[0076] As shown in Figures 10 to 11 , the rack 01 is provided with a horizontal pushing part 15 and a lifting part 16, and the horizontal pushing part 15 is located below the lifting device.

[0077] As shown in Figure 8 , the bottle box 1 is recessed along the length direction to form a containing sliding groove 11, and the containing sliding groove 11 is arranged with ampoules. The ampoules move forward by gravity or spring.

The first cam follower 562 is rotationally connected to the first cam connecting plate 563 through a bearing.

[0123] As shown in Figures 28 to 30 The second cam mechanism 57 includes a second cam motor 571, a second cam follower 572, a third cam follower 573, a second cam connecting plate 574, and a third cam connecting plate 575.

At the same time, the right clamping jaw 52 is driven to open synchronously due to the meshing position, and then the ampoule bottle is moved downward to between the left clamping jaw 51 and the right clamping jaw 52. The first cam motor 561 stops, that is, the first cam follower 562 is not in contact with the curved arm 515. At this time, under the action of the left torsional spring 514 and the right torsional spring 524, the left clamping jaw 51 and the right clamping jaw 52 move to the center, and the crank rotates synchronously until the ampoule bottle is clamped. Then the rotating disc 35 rotates until the curved arm 515 passes the light shielding sensor 58.
