Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, specifically to an injection liquid filling machine. Background Technology

[0002] In the production process of injection vials, the injection solution needs to be filled into the vial, and then a cap needs to be installed at the vial opening. Filling and capping are done in two steps: first, filling is done, and then the cap is screwed on to secure it to the vial. However, current filling and sealing machines have the following problems: they can only fill one vial at a time, and after filling, they can only seal one vial at a time. They cannot fill multiple vials simultaneously, nor can they install caps on multiple vials at the same time, resulting in low filling efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides an injection filling machine to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] An injection filling machine includes a base with wall panels connected to both sides. A Z-shaped top cover is connected to the two wall panels. A first horizontal displacement mechanism is provided on one side of the base, and a first slide is connected to the first horizontal displacement mechanism. The top surface of the first slide has several first placement slots. A fixed seat is fixed on the other side of the base, and the top surface of the fixed seat has several second placement slots. A first cylinder is installed at the lowest point of the top cover, and the telescopic end of the first cylinder is connected to a first lifting seat. A filling mechanism is installed on the first lifting seat. A second horizontal displacement mechanism is provided at the highest point of the top cover. A second slide is connected to a second horizontal displacement mechanism. Two second cylinders are mounted on the bottom surface of the second slide. The telescopic ends of the two second cylinders are connected to a second lifting seat. A bottle cap mounting mechanism is provided on the second lifting seat. The bottle cap mounting mechanism includes several rotating shafts rotatably connected to the second lifting seat. The bottom surface of the rotating shaft is provided with positioning grooves, which correspond one-to-one with the first placement groove and one-to-one with the second placement groove. Clamping mechanisms for fixing the bottle cap in the positioning grooves are provided on both sides of the lower part of the rotating shaft. The bottle cap mounting mechanism also includes a drive mechanism for driving all rotating shafts to rotate simultaneously.

[0006] Preferably, the first horizontal displacement mechanism includes a first bearing seat connected to the base, a first lead screw rotatably connected to the first bearing seat and one of the wall panels, a guide rail on the base, a first motor installed at one end of the base and driven by the first lead screw, a first slide block threadedly connected to the first lead screw, and a first slide block slidably connected to the guide rail.

[0007] The above technical solution involves starting the first motor, which drives the first lead screw to rotate. During the rotation of the first lead screw, the first slide moves along the guide rail, thereby causing the first slide to reach below the filling mechanism and the bottle cap mounting mechanism respectively.

[0008] Preferably, the filling mechanism includes an infusion tube installed in the first lifting seat, with multiple branch tubes connected to the bottom surface of the infusion tube. Each branch tube corresponds to a first storage trough. An injection tube is connected to the branch tube through a flow valve. A filling head is connected to the injection tube. One end of the infusion tube is connected to a flexible tube.

[0009] In the above technical solution, the flexible tubing is connected to the injection storage tank. During filling, the filling head is inserted into the bottle. The injection solution enters the branch tube through the tubing and infusion tube, and then enters the bottle through the filling head. The injection solution is metered by the flow valve. When the set value is reached, the flow valve closes and the filling stops, thus completing the filling of the injection solution.

[0010] Preferably, the second horizontal displacement mechanism includes a second lead screw connected to both sides of the high point of the top cover, a guide rod connected to both sides of the high point of the top cover, and a second motor mounted on the wall panel. The second motor is driven by the second lead screw, the second slide is threadedly connected to the second lead screw, and the second slide is slidably connected to the guide rod.

[0011] The above technical solution involves starting the second motor, which drives the second lead screw to rotate, thereby moving the second slide along the guide rod, allowing the bottle cap mounting mechanism to reach above the fixed seat.

[0012] Preferably, the drive mechanism includes a first bevel gear connected to the upper end of the rotating shaft, a second bearing seat connected to the second lifting seat and located at both ends of each row of rotating shafts, a transmission rod rotatably connected to the two opposing second bearing seats, a plurality of second bevel gears meshing with the first bevel gear connected to the transmission rod, a driven wheel connected to one end of each transmission rod, a third motor installed on one side of the second lifting seat, the third motor connected to a transmission shaft through a coupling, a driving wheel connected to the transmission shaft, and the driven wheel and the driving wheel being connected by a transmission belt.

[0013] The above technical solution involves starting the third motor, which drives the transmission shaft to rotate. Through the cooperation of the driving wheel, driven wheel, and transmission belt, all transmission rods rotate simultaneously. The transmission rods, through the cooperation of the second bevel gear and the first bevel gear, drive all rotating shafts to rotate simultaneously, thereby screwing the bottle caps on all rotating shafts to install the bottle caps on the corresponding bottles.

[0014] Preferably, the clamping mechanism includes a third cylinder installed on both sides of the rotating shaft, and the telescopic ends of the two third cylinders are connected to arc-shaped clamping plates. The two clamping plates are located in the positioning groove and are arranged opposite to each other.

[0015] In the above technical solution, after the second lifting seat is aligned with the fixed seat, the second cylinder is controlled to extend, driving the second lifting seat to descend so that the positioning groove fits onto the bottle cap. Then, the third cylinder is controlled to extend, and the bottle cap is fixed by the clamping plate, thereby realizing the gripping of the bottle cap.

[0016] Preferably, a first position sensor is installed on the first slide, a second position sensor that cooperates with the first position sensor is installed on the first lifting seat, a third position sensor that cooperates with the first position sensor is installed on the second lifting seat, and a fourth position sensor that cooperates with the third position sensor is installed on the fixed seat.

[0017] The above technical solution, through the cooperation of the first and second position sensors, aligns the first slide with the first lifting seat, thereby aligning the filling head with the bottle in the first storage slot. Through the cooperation of the third and fourth position sensors, the second lifting seat aligns with the fixed seat, thereby aligning the positioning slot with the bottle cap in the second storage slot. Through the cooperation of the first and third position sensors, the first slide and the second lifting seat are aligned, thereby aligning the bottle on the first slide with the bottle cap on the second lifting seat.

[0018] Preferably, a control cabinet is provided on one side of the base, and a controller is provided inside the control cabinet. A display is installed on the control cabinet. The display, the first cylinder, the second cylinder, the third cylinder, the first motor, the second motor, the third motor, the flow valve, the first position sensor, the second position sensor, the third position sensor, and the fourth position sensor are all electrically connected to the controller.

[0019] The above technical solution includes a control program written into the controller, which is used to control the opening or closing of the first cylinder, the second cylinder, the third cylinder, the first motor, the second motor, the third motor, and the flow valve.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] Several bottles can be placed in the first slot on the first slide, and several bottle caps can be placed in the second slot on the fixed seat. While the filling mechanism fills the bottles with the injection solution, the bottle cap mounting mechanism picks up the bottle caps from the fixed seat. After filling, the first horizontal displacement mechanism drives the first slide towards the fixed seat, and then the second horizontal displacement mechanism drives the second slide towards the first slide until the second lifting seat aligns with the first slide. Finally, the bottle cap mounting mechanism simultaneously mounts the picked-up bottle caps onto all the bottles, greatly improving the filling efficiency of the injection solution.

After the second lifting seat 12 is aligned with the fixed seat 6, the second cylinder 11 is controlled to extend, driving the second lifting seat 12 to descend, so that the positioning groove 7 is fitted onto the bottle cap. Then the third cylinder 34 is controlled to extend, and the bottle cap is fixed by the clamping plate 35, thereby realizing the gripping of the bottle cap.

The transmission rods, through the cooperation of the second bevel gears 30 and the first bevel gear 27, drive all the rotating shafts 13 to rotate simultaneously, thereby screwing the bottle caps on all the rotating shafts to install the bottle caps onto the corresponding bottles.

[0035] A first position sensor 36 is installed on the first slide 4, a second position sensor 37 cooperating with the first position sensor is installed on the first lifting seat 9, a third position sensor 38 cooperating with the first position sensor is installed on the second lifting seat 12, and a fourth position sensor 39 cooperating with the third position sensor is installed on the fixed seat 6.

[0037] The working principle of this embodiment is as follows: Bottles 42 are placed one by one into the first storage slot 5 on the first slide 4, and bottle caps 43 are placed into the second storage slot 7 on the fixed seat 6. The first cylinder 8 is extended, driving the first lifting seat 9 to descend, so that the filling head 22 is inserted into the bottle and filling begins. The flow valve 20 measures the volume, and when the set value is reached, the flow valve closes. Then, the first cylinder 8 is retracted, so that the filling head 22 leaves the bottle. Then, the first horizontal displacement mechanism drives the first slide 4 to move towards the fixed seat 6 until the first slide 4 abuts against the first bearing seat 15.

[0038] During filling, the second cylinder 10 extends, causing the second lifting seat 12 to descend, so that the positioning groove 14 fits around the bottle cap 43. Then, the third cylinder 34 is controlled to extend, causing the two clamping plates 35 to move relative to each other to clamp the bottle cap. Then, the second cylinder 10 retracts, causing the bottle cap 43 to leave the fixed seat 6. Next, the second horizontal displacement mechanism drives the second slide 10 to reach above the first slide 4. Then, the second cylinder 10 is controlled to extend, so that the bottle cap 43 fits onto the bottle body 42. Then, the third motor 32 is started, driving all the rotating shafts 13 to rotate simultaneously, thereby screwing the bottle cap on the corresponding bottle body, completing the bottle sealing.
