Description

Technical Field

[0001] This application relates to the field of medicine bottle sealing machine technology, specifically an automatic medicine bottle sealing machine. Background Technology

[0002] Currently, the pharmaceutical industry is booming, and the demand for automated drug packaging is increasing day by day. Among them, the capping process of bottled drugs such as oral liquids and syrups has become a key link in the automation upgrade. Efficient and precise capping automation can not only improve production efficiency, but also ensure the quality of drug packaging and meet the increasingly stringent requirements of the market.

[0003] Traditional capping operations are generally completed manually or by semi-automated mechanical equipment that relies on manual labor. This requires manual capping or manual application of caps, which is highly dependent on manpower, resulting in low efficiency, poor consistency, and high labor intensity. In recent years, automated capping equipment has gradually become more widespread, but most of them use a single capping mechanism, which is difficult to adapt to the sealing requirements of bottle caps of different sizes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an automatic medical bottle capping machine that can automatically complete bottle cap feeding, compaction, and capping operations, saving manpower, improving capping efficiency, ensuring capping quality, and adapting to the sealing requirements of bottle caps of different specifications, thereby improving the flexibility and practicality of the equipment and solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic capping machine for medical bottles, comprising a base, a first conveyor belt inside the base, a lifting platform above the base, two transmission boxes slidably connected to the upper surface of the lifting platform, two rotating shafts rotatably connected inside each transmission box, a rotating block fixedly connected to the bottom of each rotating shaft, a first lead screw rotatably connected inside the lifting platform, the outer circumferential surface of the first lead screw being threadedly connected to the inside of the transmission box, a first cylinder fixedly connected to the top of the lifting platform, and a pressure rod fixedly connected to the output end of the first cylinder.

[0006] A first bracket is fixedly connected to the upper surface of the base. A second cylinder is fixedly connected to the top of the first bracket. A pressure block is fixedly connected to the output end of the second cylinder. Two second brackets are fixedly connected to the outer surface of the base. A second conveyor belt is provided inside each of the first brackets. Two third brackets are fixedly connected to the outer surface of the base. A T-shaped slider is slidably connected to the top of each third bracket through a T-slot. A third cylinder is fixedly connected to one side of the T-shaped slider through a connecting plate. A pneumatic gripper is fixedly connected to the output end of the third cylinder. A fourth cylinder is fixedly connected to the top of each third bracket. The output end of the fourth cylinder is fixedly connected to the outer surface of the T-shaped slider. Two positioning cylinders are installed on the outer surface of the base. A positioning plate is fixedly connected to the output end of each positioning cylinder.

[0007] The above solution addresses the shortcomings of traditional manual capping, which is characterized by low efficiency, poor consistency, and high labor intensity. In recent years, automated capping equipment has largely adopted a single capping mechanism, which is insufficient to meet the sealing requirements of caps of different sizes. By incorporating a second support, a second conveyor belt, a placement trough, a third support, a T-shaped slider, a third cylinder, pneumatic grippers, and a fourth cylinder, the capping operation can be automated. Furthermore, by setting up a first cylinder, a pressure rod, a second cylinder, and a pressure block, the cap compaction operation can be automated. Finally, by setting up a transmission box, a rotating shaft, a rotating block, a positioning cylinder, and a positioning plate, the positioning and capping operations of the caps can be automated. The rotation of the first lead screw drives the transmission box and rotating block to move in opposite directions, allowing for adjustment of the spacing of the rotating blocks according to the size of the caps, thus adapting to the capping and sealing requirements of caps of different sizes.

[0008] Furthermore, the two positioning cylinders are symmetrically arranged based on the base and located directly below the lifting platform. Each of the second brackets has a sensing probe at one end near the base, with a sensing probe located above one of the positioning cylinders and a sensing probe located inside the first bracket.

[0009] With the above scheme, two positioning cylinders are symmetrically arranged on the base and located directly below the lifting platform. They can drive the positioning plate to position the bottle body during the capping process, thereby completing the subsequent capping operation. The second bracket is equipped with a sensor probe at one end near the base, above one of the positioning cylinders, and inside the first bracket. The sensor probe can detect the bottle body, so that the bottle body can accurately stop at the capping, pressing, and screwing positions, thereby completing the automatic capping, pressing, and screwing operations.

[0010] Furthermore, a motor is provided at the top of one of the rotating shafts, and the two rotating shafts are connected by a pulley and a belt drive.

[0011] The above scheme achieves synchronous rotation of the two rotating shafts, which in turn drives the rotating block to rotate synchronously, thereby automatically performing the capping operation and ensuring that the force applied to the cap during the capping process is uniform and consistent, thus improving the consistency and sealing performance of the capping.

[0012] Furthermore, a base plate is fixedly connected to one side of the base, and two columns are fixedly connected to the upper surface of the base plate. The interior of the lifting platform is slidably sleeved with the outer circumferential surface of the columns. A top plate is fixedly connected to the top of the two columns, and a second lead screw is rotatably connected to the interior of the top plate. The outer circumferential surface of the second lead screw is threadedly connected to the interior of the lifting platform.

[0013] The above solution allows the rotatable second lead screw to drive the lifting platform to move stably up and down along the column, providing precise height adjustment for the capping operation to meet the capping needs of medicine bottles of different heights, thus enhancing the versatility and flexibility of the equipment.

[0014] Furthermore, a limit rod is fixedly connected inside the lifting platform, and the inside of the transmission box is slidably connected to the outer circumferential surface of the limit rod.

[0015] The above solution guides and limits the sliding of the transmission box, preventing it from shifting during the sliding process, ensuring the stability and accuracy of the transmission box's movement, and thus ensuring the smooth progress of the sealing operation.

[0016] Furthermore, the first lead screw is a bidirectional threaded rod, the second lead screw is a unidirectional threaded rod, and a motor is provided at one end of the first lead screw.

[0017] The above scheme allows two transmission boxes to move simultaneously in opposite directions, enabling rapid adjustment, while a unidirectional threaded rod can precisely control the lifting height of the lifting platform.

[0018] Furthermore, the two second supports are located on the same side and are symmetrically arranged based on the first support, the two third supports are symmetrically arranged based on the first support, and the third supports and the second supports are symmetrically arranged based on the base. One side of the base is provided with a motor that drives the first conveyor belt to run, and one side of each second support is provided with a motor that drives the second conveyor belt to run. The outer surface of the second conveyor belt is provided with equidistantly arranged placement grooves.

[0019] With the above scheme, the second supports set on both sides of the first support can transport the inner cap and the outer cap separately by the conveyor belt, and complete the capping operation of the inner cap and the outer cap in sequence. The placement groove can limit the bottle cap, which is convenient for the bottle cap to be grasped and improves the stability of the capping operation.

[0020] Furthermore, a fixing plate is fixedly connected to one side of the base, a support rod is fixedly connected inside the fixing plate, and a control panel is fixedly connected to the top of the support rod.

[0021] The above solution facilitates the operator's monitoring and operation of the equipment, improving the convenience and comfort of operation.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This automatic medical bottle capping machine, equipped with a second support, a second conveyor belt, a placement trough, a third support, a T-shaped slider, a third cylinder, pneumatic grippers, and a fourth cylinder, can automatically complete the capping operation. With a first cylinder, a pressure rod, a second cylinder, and a pressure block, it can automatically complete the cap compaction operation. A transmission box, a rotating shaft, a rotating block, a positioning cylinder, and a positioning plate can automatically complete the cap positioning and screwing operations. The rotation of the first lead screw drives the transmission box and rotating block to move in opposite directions, and the rotation of the second lead screw drives the lifting platform to rise and fall. The spacing and height of the rotating blocks can be adjusted according to the size of the bottle cap, thus adapting to the capping and sealing requirements of different bottle cap sizes. The entire machine can automatically complete bottle cap feeding, compaction, and capping operations, saving manpower, improving capping efficiency, ensuring capping quality, and can cap bottle caps of different sizes, making it highly practical.

[0037] Please see Figure 2 , Figure 8 and Figure 9A first bracket 15 is fixedly connected to the upper surface of the base 1. A second cylinder 16 is fixedly connected to the top of the first bracket 15. A pressure block 17 is fixedly connected to the output end of the second cylinder 16. Two second brackets 18 are fixedly connected to the outer surface of the base 1. A second conveyor belt 19 is provided inside each first bracket 15. Two third brackets 21 are fixedly connected to the outer surface of the base 1. A T-shaped slider 23 is slidably connected to the top of each third bracket 21 through a T-slot. A third cylinder 24 is fixedly connected to one side of the T-shaped slider 23 through a connecting plate. A pneumatic gripper 25 is fixedly connected to the output end of the third cylinder 24. A fourth cylinder 26 is fixedly connected to the top of each third bracket 21. The output end of the fourth cylinder 26 is fixedly connected to the outer surface of the T-shaped slider 23. Two positioning cylinders 30 are installed on the outer surface of the base 1. A positioning plate 31 is fixedly connected to the output end of each positioning cylinder 30.

[0038] Please see Figure 1 , Figure 7 and Figure 8 The two positioning cylinders 30 are symmetrically arranged based on the base 1 and located directly below the lifting platform 3. Each of the second brackets 18 is equipped with a sensor probe 22 at one end near the base 1. A sensor probe 22 is located above one of the positioning cylinders 30 and inside the first bracket 15. The two positioning cylinders 30 are symmetrically arranged based on the base 1 and located directly below the lifting platform 3. They can drive the positioning plate 31 to position the bottle body during the capping process, thereby completing the subsequent capping operation. A sensor probe 22 is provided at one end of the second bracket 18 near the base 1, above one of the positioning cylinders 30, and inside the first bracket 15. The sensor probe 22 can detect the bottle body, so that the bottle body can accurately stop at the capping, pressing, and screwing positions, thereby completing the automatic capping, pressing, and screwing operations.

[0039] Please see Figure 1 , Figure 4 and Figure 5 One of the rotating shafts 5 has a motor at its top. The two rotating shafts 5 are connected by a pulley and belt drive, which realizes the synchronous rotation of the two rotating shafts 5, thereby driving the rotating block 6 to rotate synchronously, thus automatically performing the capping operation, and ensuring that the force applied to the cap during the capping process is uniform and consistent, improving the consistency and sealing of the capping.

[0040] Please see Figure 1 and Figure 3A base plate 11 is fixedly connected to one side of the base 1. Two columns 12 are fixedly connected to the upper surface of the base plate 11. The interior of the lifting platform 3 is slidably sleeved with the outer circumferential surface of the columns 12. A top plate 13 is fixedly connected to the top of the two columns 12. A second lead screw 14 is rotatably connected inside the top plate 13. The outer circumferential surface of the second lead screw 14 is threadedly connected to the interior of the lifting platform 3. The second lead screw 14 can be rotated to drive the lifting platform 3 to move up and down stably along the columns 12, providing precise height adjustment for the capping operation to adapt to the capping requirements of medicine bottles of different heights, and enhancing the versatility and flexibility of the equipment.

[0041] Please see Figure 4 The lifting platform 3 is internally fixedly connected to a limit rod 8, and the inside of the transmission box 4 is slidably connected to the outer circumferential surface of the limit rod 8. This plays a guiding and limiting role in the sliding of the transmission box 4, preventing the transmission box 4 from deviating during the sliding process, ensuring the stability and accuracy of the movement of the transmission box 4, and thus ensuring the smooth progress of the sealing operation.

[0042] Please see Figure 1 , Figure 3 and Figure 4 The first lead screw 7 is a bidirectional threaded rod, and the second lead screw 14 is a unidirectional threaded rod. One end of the first lead screw 7 is equipped with a motor. The bidirectional threaded rod can make the two transmission boxes 4 move in opposite directions at the same time to achieve rapid adjustment. The unidirectional threaded rod can precisely control the lifting height of the lifting platform 3.

[0043] Please see Figure 1 , Figure 6 and Figure 7 Two second supports 18 are located on the same side and are symmetrically arranged based on the first support 15. Two third supports 21 are symmetrically arranged based on the first support 15. The third supports 21 and the second supports 18 are symmetrically arranged based on the base 1. A motor for driving the first conveyor belt 2 is provided on one side of the base 1. A motor for driving the second conveyor belt 19 is provided on one side of each second support 18. The outer surface of the second conveyor belt 19 is provided with equidistantly arranged placement grooves 20. The second supports 18 arranged on both sides of the first support 15 allow the inner cap and the outer cap to be conveyed through the second conveyor belt 19 respectively, and the inner cap and the outer cap are put on in sequence. The placement grooves 20 can limit the bottle cap, facilitate the gripping of the bottle cap, and improve the stability of the capping operation.

[0044] Please see Figure 1 and Figure 2 A fixing plate 27 is fixedly connected to one side of the base 1. A support rod 28 is fixedly connected inside the fixing plate 27. A control panel 29 is fixedly connected to the top of the support rod 28. The setting of the control panel 29 facilitates the operator to monitor and operate the equipment, improving the convenience and comfort of operation.

[0045] This embodiment of an automatic medical bottle capping machine, by setting up a second support 18, a second conveyor belt 19, a placement groove 20, a third support 21, a T-shaped slider 23, a third cylinder 24, a pneumatic gripper 25, and a fourth cylinder 26, can automatically complete the capping operation. By setting up a first cylinder 9, a pressure rod 10, a second cylinder 16, and a pressure block 17, it can automatically complete the bottle cap compaction operation. By setting up a transmission box 4, a rotating shaft 5, a rotating block 6, a positioning cylinder 30, and a positioning plate 31, it can automatically complete the positioning and rotation of the bottle cap. In the capping operation, the first lead screw 7 rotates, driving the transmission box 4 and the rotating block 6 to move in opposite directions. The second lead screw 14 rotates, driving the lifting platform 3 to rise and fall. The spacing and height of the rotating block 6 can be adjusted according to the size of the bottle cap, thus adapting to the capping and sealing requirements of different bottle cap sizes. The entire equipment can automatically complete the bottle cap feeding, compaction, and capping operations, saving manpower, improving capping efficiency, ensuring capping quality, and can cap bottle caps of different sizes, making it highly practical.

[0046] It should be noted that a handwheel is provided at the top of the second lead screw 14, which facilitates the rotation of the second lead screw 14 via the handwheel.

[0047] It should be noted that both the positioning plate 31 and the pneumatic gripper 25 have V-shaped grooves, which can center and position the bottle cap and bottle body respectively, improving the stability of the capping and screwing process.

[0048] The working principle of the above embodiments is as follows:

[0049] The bottle body can be conveyed via the first conveyor belt 2, and the inner and outer caps can be conveyed via the second conveyor belt 19. When the bottle cap passes the second support 18, the sensor 22 detects the bottle body, and the bottle body stops moving. The pneumatic gripper 25 can be raised, lowered, and translated under the action of the third cylinder 24 and the fourth cylinder 26, thereby grabbing the inner cap in the placement slot 20 and placing it on the bottle body. Then the bottle body continues to move forward. When the bottle body moves to below the first support 15, the sensor 22 detects the bottle body, and the bottle body stops moving. The second cylinder 16 drives the pressing block 17 to move down to press the inner cap firmly. Then the bottle body continues to move forward. When the bottle body moves to the second support 18 at the rear, the sensor 22 detects the bottle body, and the bottle body stops moving. The pneumatic gripper 25 at the rear grabs the corresponding outer cap in the placement slot 20 and places it on the bottle body. Then the bottle body continues to move forward. When the bottle moves to below the lifting platform 3, the sensor 22 detects the bottle and stops moving. The positioning cylinder 30 drives the positioning plate 31 to clamp and position the bottle. Then, the first cylinder 9 drives the pressure rod 10 to move down and press the outer cap. Then, the motor at one end of the first lead screw 7 drives the first lead screw 7 to rotate, which drives the transmission box 4 to move in the opposite direction, so that the rotating block 6 clamps the bottle cap. The motor on the rotating shaft 5 drives the rotating shaft 5 to rotate. The rotating shaft 5 rotates synchronously under the action of the belt and pulley, which in turn drives the bottle cap to rotate and tightens the bottle cap, completing the capping operation. Finally, the rotating block 6 and the positioning plate 31 move back, and the first conveyor belt 2 transports the capped bottle to the next process. The second lead screw 14 can be rotated to drive the lifting platform 3 to rise and fall, thereby adjusting the height of the rotating block 6 to complete the capping operation of bottle caps of different heights.
