Description

Technical Field

[0001] The invention relates to the technical field of filling, in particular to a batch filling device for L-carnitine oral solution. Background Art

[0002] L-Carnitine oral liquid is an oral solution. After the L-Carnitine oral liquid is produced, it needs to be filled. The extension tube is inserted into the bottle by moving the nozzle, and then the oral liquid is poured into the bottle through the operation of the nozzle.

[0003] When filling the oral solution, in order to improve the accuracy of injecting the oral liquid into the bottle, the extension tube needs to be inserted into the bottle before injecting the oral liquid. However, during the insertion process, it is very easy for the extension tube to collide and rub against the inner wall of the bottle, which can easily cause damage to the oral liquid bottle. At the same time, it will cause uneven force on the bottle body when spraying the liquid, affecting the overall stability of the bottle. When the injection of oral liquid is stopped and the extension tube is removed from the oral liquid bottle, although the nozzle stops spraying the liquid, some oral liquid will still remain on the inner wall of the extension tube. This will cause the oral liquid on the inner wall of the extension tube to drip onto the surface of the oral liquid bottle and the workbench, thereby affecting the cleanliness of the equipment during use.

As the third connecting plate moves downward, the guide roller will separate from the vertical guide plate, and the V-shaped correction clamping plate will rotate to a position flush with the second connecting plate, so as to prevent the extension tube from contacting the oral liquid bottle, and also prevent the stability of the oral liquid bottle from being affected by uneven force in the bottle when the oral liquid is injected; 2. By setting up the jet discharge part, when the telescopic cylinder pushes the third connecting plate to move downward, the extension tube rotates relative to the conical exhaust bin, and at the same time, the air around the air filter bin enters the air storage box through the air filter bin and the first one-way valve. When the third connecting plate begins to shrink, the nozzle is started. In this process, the rotation of the cross partition plate is driven by the extension tube to reduce the impact force of the oral liquid entering the oral liquid bottle. When the air is injected into the conical exhaust bin through the diversion air pipe, the air blown out of the diversion air pipe impacts the oral liquid on the inner wall of the extension tube through the inclined surface of the inner wall of the conical exhaust bin. The inner wall of the extension tube can be cleaned in all directions in coordination with the rotation of the extension tube, so that the oral liquid remaining on the inner wall of the extension tube is separated from the extension tube, so that the residual oral liquid falls into the oral liquid bottle. This not only improves the accuracy of the oral liquid filling amount, but also prevents the dripping oral liquid from affecting the working environment. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0020] See also Figures 1 to 9 In an embodiment of the present invention, a batch filling device for L-carnitine oral solution includes a mounting frame 1, a second connecting plate 3 is mounted at the bottom of the mounting frame 1, a first connecting plate 2 located above the second connecting plate 3 is arranged on one side of the mounting frame 1, telescopic cylinders 510 are mounted on both sides of the first connecting plate 2, an output end of the telescopic cylinder 510 is connected to a third connecting plate 4 located between the first connecting plate 2 and the second connecting plate 3, a nozzle 503 is fixedly mounted on the top of the third connecting plate 4, a truncated cone type exhaust bin 534 is mounted at the liquid spraying port of the nozzle 503, an extension pipe 531 penetrating the third connecting plate 4 and the second connecting plate 3 is rotatably connected to the bottom end of the truncated cone type exhaust bin 534, a positioning correction piece is arranged on both sides of the second connecting plate 3, and a jet discharge piece connected to the truncated cone type exhaust bin 534 is arranged on the top of the first connecting plate 2.

[0021] In this embodiment, the device is installed above the oral liquid bottle conveying device through the mounting frame 1, and then the nozzle 503 is connected to the oral liquid storage box through the connecting pipe. When the oral liquid bottle moves to the bottom of the second connecting plate 3, the telescopic cylinder 510 is started. When the telescopic cylinder 510 is extended, the third connecting plate 4 drives the nozzle 503 to move downward, so that the extension tube 531 moves downward. During this process, the positioning correction piece operates. Through the operation of the positioning correction piece, the center line of the oral liquid bottle located below the extension tube 531 is aligned with the center line of the extension tube 531, so as to prevent the extension tube 531 from contacting the oral liquid bottle. When the telescopic cylinder 510 is fully extended, the extension tube 531 extends into the interior of the oral liquid bottle. Then, the telescopic cylinder 510 is started to shrink the telescopic cylinder 510. The nozzle 503 is operated to inject the oral liquid into the oral liquid bottle, and the extension tube 531 rises as the oral liquid level in the oral liquid bottle rises, so as to prevent the outer wall of the extension tube 531 from contacting the oral liquid. After the extension tube 531 is moved out of the oral liquid bottle, it continues to move upward, and the nozzle 503 is closed at the same time. At this time, the oral liquid remaining on the inner wall of the extension tube 531 is caused to fall into the oral liquid bottle along the inner wall of the extension tube 531 through the operation of the jet discharge member. This not only improves the accuracy of the oral liquid filling amount, but also prevents the oral liquid remaining on the inner wall of the extension tube 531 from dripping onto the outer wall of the oral liquid bottle during the transportation of the oral liquid bottle. When the telescopic cylinder 510 is fully retracted, the oral liquid bottle containing the oral liquid is moved out from under the second connecting plate 3 by an external conveying device, and the empty bottle is moved to the bottom of the second connecting plate 3 for filling.

[0022] Please refer to Figure 5 , Figure 6 A bearing is provided at the portion where the outer wall of the extension tube 531 is connected to the third connecting plate 4, and the extension tube 531 is rotatably connected to the third connecting plate 4 through the bearing.

[0023] In this embodiment, this structure is provided to provide a rotation space for the extension tube 531 , and also increases the stability of the connection between the extension tube 531 and the third connecting plate 4 , thereby preventing the extension tube 531 from shifting left and right relative to the third connecting plate 4 .

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4The positioning correction member includes a V-shaped correction clamping plate 509 rotatably connected to both sides of the second connecting plate 3 through a rotating shaft, and first transmission spur gears 512 are installed at both ends of the rotating shaft connecting the V-shaped correction clamping plate 509 and the second connecting plate 3. A second side connecting sleeve 513 located on one side of the second connecting plate 3 is provided on the mounting frame 1, and a first piston rod 518 extending to the outside of the second side connecting sleeve 513 is inserted in the interior of the second side connecting sleeve 513, and an end of the first piston rod 518 away from the second side connecting sleeve 513 is rotatably connected to an extrusion rod 519 through a rotating shaft. A guide seat 520 located between the second side connecting sleeve 513 and the second connecting plate 3 is provided on the mounting frame 1, and movable racks 521 meshing with the first transmission spur gear 512 are movably sleeved on both sides of the guide seat 520, and an end of the extrusion rod 519 away from the first piston rod 518 is rotatably connected to the movable rack 521 through a rotating shaft. A side connecting frame 517 is installed, and a vertical guide plate 516 is fixedly installed on the inner side of the side connecting frame 517. The top of the vertical guide plate 516 is rotatably connected to the inclined guide plate 515 through a rotating shaft. The outer side of the rotating shaft connecting the inclined guide plate 515 and the vertical guide plate 516 is clamped with a torsion spring 525 connected to the inclined guide plate 515 through a clamping groove. A limiting clamping block 526 is provided on the side of the inclined guide plate 515 close to the side connecting frame 517. The first side connecting sleeve 501 is installed on both sides of the third connecting plate 4. The interior of the first side connecting sleeve 501 is plugged with a second piston rod 524 extending to the outside of the first side connecting sleeve 501. The second piston rod 524 is provided with a first return spring 522 connected to the first side connecting sleeve 501. Guide rollers 523 located above the inclined guide plate 515 are provided on both sides of the second piston rod 524. A second hose 514 connected to the second side connecting sleeve 513 is provided at the bottom of the first side connecting sleeve 501.

[0025] In this embodiment, when the third connecting plate 4 moves downward relative to the second connecting plate 3, due to the blocking of the limiting block 526 by the side connecting frame 517, the guide roller 523 will move toward the first side connecting sleeve 501 under the inclined guidance of the inclined guide plate 515, so that the second piston rod 524 squeezes the aqueous solution inside the first side connecting sleeve 501. At this time, the aqueous solution inside the first side connecting sleeve 501 enters the second side connecting sleeve 513 through the second hose 514, so that the first piston rod 518 moves away from the second side connecting sleeve 501. The side connecting sleeve 513 moves in the direction of the first piston rod 518, so that the first piston rod 518 squeezes the squeezing rod 519 to make the movable rack 521 move in the direction away from the guide seat 520, so that the movable rack 521 drives the V-shaped correction clamping plate 509 to swing by toggling the first transmission spur gear 512, so that the V-shaped correction clamping plate 509 is buckled on the outer wall of the oral liquid bottle, so as to correct the oral liquid bottle, so that the center of the oral liquid bottle is aligned with the center of the extension tube 531, and as the third connecting plate 4 moves downward, the guide roller 523 When the telescopic cylinder 510 is fully extended, the guide roller 523 is separated from the vertical guide plate 516. At this time, the second piston rod 524 is extended and restored under the elastic restoring force of the first return spring 522, and the guide roller 523 is moved from the bottom of the vertical guide plate 516 to the bottom of the oblique guide plate 515, so that the aqueous solution in the second side connecting sleeve 513 enters the first side connecting sleeve 501, and the movable rack 521 is restored, so that the V-shaped correction clamp 5 09 turns to a position flush with the second connecting plate 3. When the telescopic cylinder 510 drives the third connecting plate 4 to move upward, the guide roller 523 will move toward the inclined guide plate 515. When the guide roller 523 contacts the bottom of the inclined guide plate 515, the third connecting plate 4 continues to shrink. At this time, the guide roller 523 will push the inclined guide plate 515, causing the inclined guide plate 515 to rotate clockwise relative to the side connecting frame 517. When the guide roller 523 separates from the inclined guide plate 515, the inclined guide plate 515 will restore under the action of the elastic restoring force of the torsion spring 525.

[0026] Please refer to Figure 3 The distance between the bottom end of the vertical guide plate 516 and the bottom of the mounting frame 1 is greater than the diameter of the guide roller 523 , and the horizontal height of the inclined guide plate 515 away from one end of the first side connecting sleeve 501 is greater than the horizontal height of the inclined guide plate 515 close to one end of the first side connecting sleeve 501 .

[0027] In this embodiment, this structure is provided to enable the inclined guide plate 515 to guide the guide roller 523 when the first side connecting sleeve 501 moves downward along with the third connecting plate 4. At the same time, when the guide roller 523 moves to the lowest point, the guide roller 523 moves to the bottom of the inclined guide plate 515 under the action of the elastic restoring force of the first return spring 522, thereby realizing the one-way limiting of the guide roller 523 by the inclined guide plate 515.

[0028] Please refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The jet discharge part includes an air storage box 504 installed on the top of the first connecting plate 2, a first non-return valve 505 is installed on the top of the air storage box 504, an air filter compartment 506 is installed on the top of the first non-return valve 505, and a second non-return valve 507 located on both sides of the first non-return valve 505 is installed on the top of the air storage box 504. A piston plate 540 is slidably connected to the inside of the air storage box 504, and a first pull rod 502 that passes through the first connecting plate 2 is installed at the bottom of the piston plate 540. A cavity 536 is opened at the bottom of the first pull rod 502, and a second pull rod 533 extending to the outside of the cavity 536 and connected to the top of the third connecting plate 4 is inserted into the cavity 536. A second return spring 537 connected to the second pull rod 533 is installed in the cavity 536, and the outer wall of the extension tube 531 is installed with A worm gear 528 is located above the third connecting plate 4, and a synchronous wheel 529 located above the worm gear 528 is installed on the outer wall of the extension tube 531, and a synchronous belt 530 is arranged on the outer side of the synchronous wheel 529. The top of the third connecting plate 4 is rotatably connected to a worm 527 meshing with the worm gear 528, and second transmission spur gears 539 are installed at both ends of the worm 527. Positioning racks 511 meshing with the second transmission spur gears 539 are fixedly installed on both sides of the second connecting plate 3. A diverter air pipe 538 is connected to the outer side of the truncated cone exhaust chamber 534, and an exhaust connecting pipe 532 is installed at one end of the diverter air pipe 538 away from the truncated cone exhaust chamber 534. A first hose 508 connected to the second one-way valve 507 is arranged on the top of the exhaust connecting pipe 532, and a cross partition plate 535 is installed on the inner wall of the bottom end of the extension tube 531.

[0029] In this embodiment, when the telescopic cylinder 510 pushes the third connecting plate 4 to move downward, the second transmission spur gear 539 will rotate along the positioning rack 511, so that the worm 527 drives the extension pipe 531 to rotate through the worm gear 528, so that the extension pipe 531 rotates relative to the frustum-shaped exhaust chamber 534. In the process of the third connecting plate 4 moving downward, the first pull rod 502 moves downward synchronously with the second pull rod 533, so that the air around the air filter chamber 506 passes through the air filter chamber 506 and the first one-way valve 5 05 enters the air storage box 504. When the bottom of the piston plate 540 fits against the inner wall of the air storage box 504, the third connecting plate 4 continues to move downward. At this time, the second pull rod 533 will move downward relative to the first pull rod 502, so that the cavity 536 is squeezed. When the third connecting plate 4 begins to shrink, the nozzle 503 is started. The operation of the nozzle 503 is used to inject the oral liquid into the oral liquid bottle through the truncated cone exhaust chamber 534 and the extension tube 531. In this process, the rotation of the cross partition plate 535 is driven by the extension tube 531 to reduce the oral liquid entering the oral The impact force of the liquid bottle is released, and the cavity 536 stretches and recovers, so that the top of the second pull rod 533 fits with the cavity 536, and the injection of oral liquid is stopped. At this time, when the third connecting plate 4 continues to move upward, the second pull rod 533 will push the first pull rod 502 to move upward, so that the purified air inside the air storage box 504 is injected into the frustum-shaped exhaust chamber 534 through the second one-way valve 507, the first hose 508, the exhaust connecting pipe 532, and the shunt air pipe 538. At this time, the shunt air pipe 538 blows out through the inclined surface of the inner wall of the frustum-shaped exhaust chamber 534. The air released impacts the oral liquid on the inner wall of the extension tube 531, and the inner wall of the extension tube 531 can be cleaned in all directions in coordination with the rotation of the extension tube 531, so that the oral liquid remaining on the inner wall of the extension tube 531 is separated from the extension tube 531, so that the remaining oral liquid falls into the oral liquid bottle, and then the oral liquid bottle containing the oral liquid can be transported, so as to prevent the remaining oral liquid from dripping to the outside of the oral liquid bottle, which not only improves the accuracy of the oral liquid filling amount, but also prevents the dripping oral liquid from affecting the working environment.
