Description

Technical Field

[0001] This utility model relates to the field of drug packaging technology, specifically a sealing mechanism for drug packaging. Background Technology

[0002] Creams are ointment-like preparations made by adding dispersants to one or more liquid agents that are poorly soluble in water or solid agents that are soluble in a suitable organic solvent. After being made, creams need to be bottled for easy sale.

[0003] A search revealed a sealing device for cream-type drugs with application number 202121338748.4. This device, consisting of a motor, turntable, circular groove, bottle body, pump body, extraction pipe, discharge pipe, filling head, hydraulic cylinder, and sealing machine, facilitates the filling and sealing of bottles. The filling and sealing operation is simple and convenient, improving the processing efficiency of creams. However, this device can only seal a single product and cannot clamp bottles of other sizes, resulting in limited applicability. Furthermore, during the filling process, empty bottles need to be manually placed one by one into the groove on the turntable, and then removed one by one after filling, leading to low production efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a sealing mechanism for drug packaging to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing mechanism for drug packaging, comprising a base, a drug filling mechanism, and a capping mechanism. The top of the base is connected to an mounting plate and a support plate. First magnets are provided on both sides of the mounting plate. A fixing plate is connected to the top of the support plate. A motor is provided at the bottom of the base. A rotating shaft is connected to the output end of the motor. A rotating disk is connected to one end of the rotating shaft. A guide groove is formed on the outer surface of the rotating disk. A sliding groove is provided on the inner wall of the guide groove. A clamping plate is connected to the inner wall of the guide groove via a damping rod and a spring. Slider blocks are connected to both sides of the clamping plate. A second magnet is provided on the back of the clamping plate.

[0006] Furthermore, the rotating disk is slidably connected to the fixed plate and the bearing plate respectively.

[0007] By adopting the above technical solution, the rotating shaft drives the rotating disk to rotate under the drive of the motor. The medicine bottle is detached from the conveyor belt and enters the carrier plate through the guide groove. The carrier plate supports the medicine bottle. When the second magnet loses its attraction to the first magnet, the damping rod drives the clamping plate to move under the action of the spring force. The clamping plate cooperates with the fixed plate to clamp the medicine bottle for subsequent processing.

[0008] Furthermore, both the first magnet and the second magnet are neodymium magnets, and the first magnet and the second magnet have different magnetic properties.

[0009] By adopting the above technical solution, when the second magnet rotates above the conveyor belt, the magnetic attraction between the first magnet and the second magnet causes the second magnet to move the clamping plate, thereby squeezing the spring and the damping rod, so that the clamping plate moves to one side of the guide groove, so that the medicine bottle can enter or leave the guide groove.

[0010] Furthermore, the two first magnets are symmetrically distributed, and one side of each first magnet is arc-shaped.

[0011] By adopting the above technical solution, two first magnets are respectively located at one end of the two sets of conveyor belts. The clamping plate is fixed to one side of the guide groove by magnetic attraction between the first magnet and the second magnet, so that the medicine bottle can enter or leave the guide groove. The arc-shaped setting can avoid interference between the first magnet and the rotating disk when the rotating disk rotates.

[0012] Furthermore, there are multiple guide slots, clamping plates, second magnets, springs and damping rods, and these multiple guide slots, clamping plates, second magnets, springs and damping rods are arranged in a circular array.

[0013] By adopting the above technical solution, the rotating shaft drives the rotating disk to rotate under the drive of the motor output. During the rotation, the magnetism between the second magnet and the first magnet weakens until they separate. Under the action of the spring force, the clamping plate is slowly moved by the damping rod, so that the clamping plate pushes the medicine bottle to abut against the fixed plate, thereby clamping medicine bottles of different sizes and improving the practicality of the device.

[0014] Furthermore, the slider is slidably connected to the groove.

[0015] By adopting the above technical solution, the clamping plate is limited by the cooperation of the sliding groove and the slider, which prevents the clamping plate from popping out of the guide groove under the action of the spring force. At the same time, the sliding groove limits the maximum distance of movement of the clamping plate, which prevents the second magnet and the first magnet from being too far apart, so that their magnetism weakens and they can no longer attract each other, thus affecting the practicality of the device.

[0016] Furthermore, the outer surface of the clamping plate has a notch, and the notch is V-shaped.

[0017] By adopting the above technical solution, when clamping medicine bottles of different sizes, the "V" shape setting ensures that there are always two or more support points between the clamping plate and the medicine bottle, thereby enhancing the clamping effect and preventing the medicine bottle from sliding left and right on the outer surface of the clamping plate.

[0018] Furthermore, the base is provided with two sets of conveyor belts at the top, and the two sets of conveyor belts are symmetrically distributed.

[0019] By adopting the above technical solution, the two sets of conveyor belts transmit in opposite directions. One set of conveyor belts continuously feeds the medicine bottles into the guide trough, while the other set of conveyor belts continuously removes the sealed medicine bottles from the guide trough, thereby realizing streamlined production and improving production efficiency.

[0020] Furthermore, both the fixing plate and the clamping plate have soft pads on their outer surfaces, and the soft pads are made of sponge material.

[0021] By adopting the above technical solution, when the medicine bottle rotates with the rotating disk, the soft pad cushions the medicine bottle, preventing the clamping plate and fixing plate from scratching the medicine bottle and affecting its appearance.

[0022] Furthermore, baffles are connected to both sides of the conveyor belt.

[0023] By adopting the above technical solution, baffles are used to block both sides of the conveyor belt, preventing medicine bottles from slipping off the conveyor belt during transportation and affecting production efficiency.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model is equipped with a guide groove, a clamping plate, a second magnet, a first magnet, a spring, and a damping rod. Driven by the output of a motor, the rotating shaft drives the rotating disk to rotate. During the rotation, the magnetism between the second magnet and the first magnet weakens until they separate. Under the action of the spring force, the clamping plate is slowly moved by the damping rod, so that the clamping plate pushes the medicine bottle to abut against the fixed plate, thereby clamping medicine bottles of different sizes and improving the practicality of the device.

[0026] 2. This utility model, by setting up a conveyor belt and baffles, allows for production by continuously feeding medicine bottles into the guide trough via one set of conveyor belts. Under the drive of the rotating disc, the medicine filling and capping process is completed, and the bottles fall into another set of conveyor belts. The other set of conveyor belts continuously removes the sealed medicine bottles from the guide trough, realizing streamlined production and thus improving production efficiency. The baffles shield both sides of the conveyor belt to prevent the medicine bottles from slipping off the conveyor belt during transportation. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1: A sealing mechanism for drug packaging, such as Figures 1-4 As shown, the device includes a base 1, a filling mechanism 17, and a capping mechanism 18. The top of the base 1 is connected to a mounting plate 6 and a support plate 14. First magnets 13 are provided on both sides of the mounting plate 6. A fixing plate 15 is connected to the top of the support plate 14. A motor 3 is located at the bottom of the base 1. A rotating shaft 4 is connected to the output end of the motor 3. A rotating disk 5 is connected to one end of the rotating shaft 4. A guide groove 7 is provided on the outer surface of the rotating disk 5. A sliding groove 8 is provided on the inner wall of the guide groove 7. A clamping plate 10 is connected to the inner wall of the guide groove 7 via a damping rod 11 and a spring 12. A notch is provided on the outer surface of the clamping plate 10, and the notch is "V"-shaped. When clamping medicine bottles of different sizes, the "V" shape ensures that there are always two or more support points between the clamping plate 10 and the medicine bottle, enhancing the clamping effect and preventing the medicine bottle from sliding left and right on the outer surface of the clamping plate 10. Slider blocks 9 are connected to both sides of the clamping plate 10, and a second magnet 16 is provided on the back of the clamping plate 10.

[0036] See Figure 1 , Figure 2 and Figure 5 In the above embodiment, the rotating disk 5 is slidably connected to the fixed plate 15 and the bearing plate 14 respectively. Driven by the motor 3, the rotating shaft 4 drives the rotating disk 5 to rotate. The medicine bottle is separated from the conveyor belt 2 and enters the bearing plate 14 through the guide groove 7. The bearing plate 14 supports the medicine bottle. When the second magnet 16 loses its attraction to the first magnet 13, the damping rod 11 drives the clamping plate 10 to move under the action of the spring 12. The clamping plate 10 cooperates with the fixed plate 15 to clamp the medicine bottle for subsequent processing.

[0037] See Figure 2 and Figure 3 In the above embodiment, both the first magnet 13 and the second magnet 16 are neodymium magnets, and the first magnet 13 and the second magnet 16 have different magnetic properties. When the second magnet 16 rotates above the conveyor belt 2, the magnetic attraction between the first magnet 13 and the second magnet 16 causes the second magnet 16 to drive the clamping plate 10 to move, thereby squeezing the spring 12 and the damping rod 11, so that the clamping plate 10 moves to one side of the guide groove 7 so that the medicine bottle can enter or leave the guide groove 7.

[0038] See Figure 2 and Figure 3 In the above embodiment, the two first magnets 13 are symmetrically distributed, and one side of the two first magnets 13 is arc-shaped. The two first magnets 13 are respectively located at one end of the two sets of conveyor belts 2. The clamping plate 10 is fixed to one side of the guide groove 7 by magnetic attraction between the first magnet 13 and the second magnet 16, so that the medicine bottle can enter or leave the guide groove 7. The arc-shaped setting can avoid interference between the first magnet 13 and the rotating disk 5 when the rotating disk 5 rotates.

[0039] See Figure 1 and Figure 5 In the above embodiment, there are several guide grooves 7, clamping plates 10, second magnets 16, springs 12 and damping rods 11, and several guide grooves 7, clamping plates 10, second magnets 16, springs 12 and damping rods 11 are arranged in a circular array. Driven by the output end of motor 3, the rotating shaft 4 drives the rotating disk 5 to rotate. During the rotation, the magnetism between the second magnet 16 and the first magnet 13 weakens until they separate. Under the elastic force of spring 12, the clamping plate 10 is slowly moved by the damping rod 11, so that the clamping plate 10 pushes the medicine bottle to abut against the fixed plate 15, thereby clamping medicine bottles of different sizes and improving the practicality of the device.

[0040] See Figures 1-5 In the above embodiment, the slider 9 is slidably connected to the slide groove 8. The slide groove 8 and the slider 9 cooperate to limit the clamping plate 10, so as to prevent the clamping plate 10 from popping out of the guide groove 7 under the elastic force of the spring 12. At the same time, the slide groove 8 limits the maximum distance of movement of the clamping plate 10, so as to prevent the second magnet 16 and the first magnet 13 from being too far apart, which would weaken their magnetism and prevent them from attracting each other, thus affecting the practicality of the device.

[0041] See Figure 1 and Figure 5In the above embodiment, the base 1 is provided with two sets of conveyor belts 2 at the top, and the two sets of conveyor belts 2 are symmetrically distributed. Baffles 20 are connected to both sides of the conveyor belts 2. The two sets of conveyor belts 2 have opposite transmission directions. One set of conveyor belts 2 continuously feeds the medicine bottles into the guide groove 7, while the other set of conveyor belts 2 continuously removes the packaged medicine bottles from the guide groove 7, realizing streamlined production and thus improving production efficiency. The baffles 20 block the two sides of the conveyor belts 2 to prevent the medicine bottles from sliding out of the conveyor belts 2 during transmission.

[0042] Example 2: To prevent the outer surface of the medicine bottle from being scratched during rotation, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 5 Both the fixing plate 15 and the clamping plate 10 have soft pads 19 on their outer surfaces. The soft pads 19 are made of sponge material. When the medicine bottle rotates with the rotating disk 5, the soft pads 19 cushion the medicine bottle and prevent the clamping plate 10 and the fixing plate 15 from scratching the medicine bottle and affecting its appearance.

[0043] The implementation principle of this utility model is as follows: During the filling process, the empty medicine bottle enters the guide groove 7 under the transmission drive of the conveyor belt 2. The operator starts the motor 3, and under the drive of the output end of the motor 3, the rotating shaft 4 drives the rotating disk 5 to rotate, so that the guide groove 7 drives the empty bottle to rotate. At this time, the magnetism between the second magnet 16 and the first magnet 13 weakens. Under the action of the spring force of the spring 12, the damping rod 11 slowly drives the clamping plate 10 to push the empty bottle to move. At the same time, the slider 9 moves in the slide groove 8 to guide the clamping plate 10 until the empty bottle contacts the fixed plate 15. The fixed plate 15 and the clamping plate 10 cooperate to clamp the medicine bottle, so that the medicine bottle moves on the carrier plate 14. When the medicine bottle moves to the filling mechanism 17, the bottle moves to the filling mechanism 17. When the medicine is placed below, the ointment is squeezed into the medicine bottle through the filling mechanism 17. Then, the staff puts the cap on the mouth of the medicine bottle. When the medicine bottle with the cap is moved below the capping mechanism 18, the capping mechanism 18 tightens the cap, and the processing is completed. (The filling mechanism 17 and the capping mechanism 18 mentioned above are existing technologies and will not be described in detail in this case.) When the processed product is rotated to the top of the conveyor belt 2 on the other side, at this time, under the action of magnetic force, the first magnet 13 and the second magnet 16 attract each other, so that the second magnet 16 drives the clamping plate 10 to squeeze and contract the spring 12 and the damping rod 11, so that the clamping plate 10 and the fixing plate 15 are separated from the medicine bottle, and the conveyor belt 2 transfers the processed medicine bottle out of the guide groove 7.
