[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0029] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0030] Example 1

[0031] For easier understanding, see Figures 1 to 7 A water injection filling machine provided in an embodiment of the present application includes a bottle feeding mechanism, a front nitrogen filling mechanism 20, a filling mechanism 30, a rear nitrogen filling mechanism 40, a wire drawing sealing mechanism 50 and a nitrogen air curtain exhaust 60.

[0032] The bottle feeding mechanism comprises a bottle feeding conveyor belt 10, and a front nitrogen filling mechanism 20, a filling mechanism 30, a rear nitrogen filling mechanism 40 and a wire drawing and sealing mechanism 50 are sequentially arranged in the conveying direction of the bottle feeding conveyor belt 10; the bottle feeding conveyor belt 10 performs intermittent rotational motion, and the bottle feeding conveyor belt 10 drives the ampoule bottles to sequentially pass through the front nitrogen filling mechanism 20, the filling mechanism 30, the rear nitrogen filling mechanism 40 and the wire drawing and sealing mechanism 50. A nitrogen gas curtain row 60 is arranged above the bottle feeding conveyor belt 10 between the entrance of the bottle feeding mechanism and the front nitrogen filling mechanism 20, and a nitrogen gas curtain row 60 is arranged above the bottle feeding conveyor belt 10 between the rear nitrogen filling mechanism 40 and the wire drawing and sealing mechanism 50.

[0033] The interior of the nitrogen gas curtain row 60 is a hollow air cavity 61, and the cross-section of the air cavity 61 in the width direction is an inverted trapezoid. An air inlet pipe 62 connected to the air cavity 61 is provided on the outer wall of the nitrogen gas curtain row 60, and the air cavity 61 can temporarily accommodate the nitrogen flowing in from the air inlet pipe 62.

[0034] like Figure 3 As shown, a strip-shaped gas outlet 63 is provided at the bottom of the nitrogen gas curtain row 60 in the extending direction. The gas outlet 63 is parallel to the conveying direction of the bottle conveyor belt 10. The gas outlet 63 is connected to the air cavity 61. Nitrogen gas flows from the air cavity 61 through the strip-shaped gas outlet 63 to form a nitrogen gas curtain. In this embodiment, as shown in FIG. Figure 2 As shown, the shape of the air cavity 61 in the width direction is set to be an inverted trapezoid, a through air outlet 63 is set at the bottom of the inverted trapezoidal air cavity 61, and a through air inlet pipe 62 is set on the side wall or the upper wall of the inverted trapezoidal air cavity 61. The nitrogen gas that continuously enters the inverted trapezoidal air cavity 61 obtains a larger flow rate when flowing out from the air outlet 63 due to the inverted trapezoidal shape, so that the air in the ampoule bottle below the nitrogen air curtain row 60 is better replaced.

[0035] The shape of the air cavity 61 is not limited to an inverted trapezoid, but can also be an inverted triangle or a semicircle. The air outlet 63 and the air inlet pipe 62 are adaptively arranged to connect the air cavity 61, so that the nitrogen gas can obtain a higher flow rate when it comes out of the air outlet 63. In order to obtain a higher flow rate for the nitrogen gas flowing out of the air outlet 63, the air inlet pipe 62 and the air outlet 63 can also be modified, such as setting the width of the air outlet 63 to be smaller than the diameter of the air inlet pipe 62, and the air inlet pipe 62 continuously transports nitrogen gas to the air cavity 61, which also allows the nitrogen gas flowing out of the air outlet 63 to obtain a higher flow rate.

[0036] Baffles 64 are provided on both sides of the air outlet 63, and the baffles 64 form a passage for the mouth of the ampoule bottle to pass through.

[0037] It can be seen from the above technical solution that the intermittent rotation of the bottle conveyor belt 10 drives the ampoule bottle to intermittently move forward from the entrance of the bottle feeding mechanism. The ampoule bottle is always in the nitrogen air curtain formed by the narrow and long strip-shaped air outlet 63 of the nitrogen air curtain row 60 when reaching the front nitrogen filling mechanism 20 or the wire drawing and sealing mechanism 50. The nitrogen air curtain enters the ampoule bottle to replace the air in the bottle. The baffles 64 on both sides of the air outlet 63 form a channel for the bottle mouth of the ampoule bottle to pass through. The continuously sprayed nitrogen air curtain and the excess nitrogen overflowing from the ampoule bottle form a nitrogen protection area in the channel. The bottle mouth of the ampoule bottle is always in the nitrogen protection area, which solves the technical problem that the ampoule bottle lacks nitrogen protection throughout the process from the bottle feeding process to the wire drawing and sealing process.

[0038] Example 2

[0039] For easier understanding, see Figure 1 and Figure 4 The embodiment of the present application is a further improvement on embodiment 1. In the present embodiment, it also includes an air curtain lifting mechanism for installing the nitrogen gas curtain row 60. The air curtain lifting mechanism includes a lifting rod 90, a locking device 92 and a fixing plate 91. The lifting rod 90 is arranged on one side of the bottle conveyor belt 10. The fixing plate 91 is slidably arranged on the lifting rod 90. One end of the fixing plate 91 is fixedly connected to the nitrogen gas curtain row 60. The lifting rod 90 is provided with a thread. The locking device 92 includes two nuts located at the upper and lower ends of the fixing plate 91. The two nuts cooperate with the lifting rod 90 thread to clamp the fixing plate 91 to lock and fix the nitrogen gas curtain row 60 on the lifting rod 90.

[0040] It should be noted that in the production of water injection filling, the bottle mouth heights of ampoules of different specifications are different, and the height of the nitrogen gas curtain row 60 needs to be adjusted according to the specifications of the ampoule bottle, so that the nitrogen gas curtain sprayed by the nitrogen gas curtain row 60 can replace the air in the ampoule bottle to achieve the best effect. When the height of the nitrogen gas curtain row 60 needs to be increased, first loosen the nut above the fixed plate 91, move it upward along the lifting rod 90 to a predetermined height, and then raise the nitrogen gas curtain row 60 along the lifting rod 90 to the position of the nut above the fixed plate 91, rotate the nut below the fixed plate 91 and move it upward along the lifting rod 90 until it cooperates with the nut above the fixed plate 91 to clamp the fixed plate 91, so that the nitrogen gas curtain row 60 is locked and fixed at a predetermined height. If the height of the nitrogen gas curtain row 60 needs to be lowered, first loosen the nut under the fixed plate 91, move it downward along the lifting rod 90 to a predetermined height, and then lower the nitrogen gas curtain row 60 along the lifting rod 90 to the position of the nut under the fixed plate 91, rotate the nut above the fixed plate 91 and move it downward along the lifting rod 90 until it cooperates with the nut under the fixed plate 91 to clamp the fixed plate 91, so that the nitrogen gas curtain row 60 is locked and fixed at a predetermined height.

[0041] Example 3

[0042] For easier understanding, see Figure 1 and Figure 5 The embodiment of the present application is a further improvement on the embodiment 1 or 2. The bottle conveyor belt 10 includes a conveyor block 11, which is arranged on the bottle conveyor belt 10. The outer side of the conveyor block 11 has an arc-shaped notch 12. The arc-shaped notch 12 matches the shape of the bottle body of the ampoule bottle. The bottle conveyor belt 10 is evenly provided with a plurality of conveyor blocks 11. The arc-shaped notch 12 of the conveyor block 11 accommodates the ampoule bottle. The bottle conveyor belt 10 rotates intermittently, driving the transmission block 11 to move forward, so that the ampoule bottle passes through the front nitrogen filling mechanism 20, the filling mechanism 30, the rear nitrogen filling mechanism 40 and the wire drawing and sealing mechanism 50 in sequence. The front nitrogen filling mechanism 20, the filling mechanism 30, the rear nitrogen filling mechanism 40 and the wire drawing and sealing mechanism 50 are also arranged at the same intervals, and the distance between every two conveyor blocks 11 is equal to the interval between each mechanism. That is, at the same time, the front nitrogen filling mechanism 20, the filling mechanism 30, the rear nitrogen filling mechanism 40 and the wire drawing sealing mechanism 50 respectively correspond to a conveying block 11, and perform corresponding operations on the ampoule bottle at the same time to improve the working efficiency of the water injection filling and sealing machine.

[0043] Furthermore, a side plate 13 is provided on the outer side of the straight section of the bottle conveyor belt 10 , and when the conveying block 11 drives the ampoule bottle to move forward, the side plate 13 restricts the ampoule bottle from escaping from the arc-shaped notch 12 .

[0044] Example 4

[0045] For easier understanding, see Figure 5 The embodiment of the present application is a further improvement of the embodiment 1, 2 or 3. In the embodiment, it also includes a bottle unscrambling mechanism, which includes a bottle feeding mesh belt 70, an auger 71 and a bottle-pushing wheel 72. The auger 71 is arranged at the end of the bottle feeding mesh belt 70 in the moving direction, and the bottle-pushing wheel 72 is arranged at the end of the auger 71 in the rotating conveying direction. The bottle-pushing wheel 72 has a plurality of bottle-pushing grooves 73 along its circumference. The bottle-pushing wheel 72 is connected to the entrance of the bottle-feeding conveyor belt 10. The periphery of the bottle-pushing wheel 72 is provided with an arc-shaped guard plate 74. When the bottle-pushing wheel 72 and the bottle-feeding conveyor belt 10 rotate at the same time, the bottle-pushing grooves 73 correspond to the conveying block 11 one by one. A guide rod is arranged at the entrance of the bottle-feeding conveyor belt 10. When the bottle-pushing grooves 73 rotate to the entrance of the bottle-feeding conveyor belt 10, the guide rod guides the ampoule bottles in the bottle-pushing grooves 73 into the conveying block 11.

[0046] It should be noted that a large number of ampoules are piled on the bottle feeding mesh belt 70. The bottle feeding mesh belt 70 moves forward and drives the ampoules to the auger 71 at the end of the moving direction of the bottle feeding mesh belt 70. The auger 71 rotates intermittently to move the disordered ampoules in an orderly manner along the axial direction of the auger 71, and intermittently enters the bottle-moving groove 73 of the bottle-moving wheel 72. The bottle-moving wheel 72 also rotates intermittently, driving the ampoules that have entered the bottle-moving groove 73 to move toward the bottle-feeding conveyor belt 10. When the ampoules reach the entrance of the bottle-feeding conveyor belt 10, they are transferred to the arc-shaped recess 12 of the conveying block 11. The outer periphery of the bottle-moving wheel 72 is provided with an arc-shaped guard plate 74. On the arc-shaped route from the auger 71 to the bottle-feeding conveyor belt 10, when the bottle-moving wheel 72 transfers the ampoules, the arc-shaped guard plate 74 prevents the ampoules from being thrown out of the bottle-moving groove 73 due to centrifugal force.

[0047] Example 5

[0048] For easier understanding, see Figure 1 The embodiment of the present application is a further improvement of embodiment 1 or 2 or 3 or 4. In this embodiment, the wire drawing sealing mechanism 50 includes a high temperature flame spray nozzle, a wire drawing clamp 51 and a second lifting mechanism. The high temperature flame spray nozzle is arranged on one side of the bottle conveyor belt 10. The wire drawing clamp 51 is installed on the second lifting mechanism. The second lifting mechanism is on one side of the bottle conveyor belt 10. The wire drawing clamp 51 is located above the bottle conveyor belt 10. After the ampoule bottle is filled with liquid medicine, it is transferred to the wire drawing sealing mechanism 50 by the bottle conveyor belt 10 for sealing. The high temperature flame spray nozzle arranged on one side of the bottle conveyor belt 10 sprays fire and heats the bottleneck of the ampoule bottle. The bottleneck of the ampoule bottle is heated to a molten state. The wire drawing clamp 51 located above the bottle conveyor belt 10 descends to the bottleneck position of the ampoule bottle through the second lifting mechanism to clamp the molten bottleneck, and then rises through the second lifting mechanism to perform wire drawing sealing of the ampoule bottle.

[0049] Specifically, the second lifting mechanism includes a mounting plate, a slide rail 80, a lead screw 81, a lead screw nut and a driving motor. The wire drawing clamp 51 is fixed on the mounting plate, the mounting plate is slidably connected to the slide rail 80, the mounting plate is connected to the lead screw 81 through the lead screw nut, and the lead screw 81 is connected to the driving motor. The mounting plate is slidably arranged on the slide rail 80, the driving motor drives the lead screw 81 to rotate in forward and reverse rotation, the lead screw nut moves up and down along the lead screw 81, and the mounting plate also moves up and down accordingly, so that the wire drawing clamp 51 can move up and down to approach or move away from the bottleneck of the ampoule bottle.

[0050] Example 6

[0051] For easier understanding, see Figure 1 and Figure 6 The embodiment of the present application is a further improvement on embodiment 1 or 2 or 3 or 4 or 5.

The front nitrogen filling mechanism 20, the filling mechanism 30 and the rear nitrogen filling mechanism 40 are all arranged on the first lifting mechanism, and they are lifted and lowered together with the first lifting mechanism.
