Description
Technical Field
[0001] This utility model relates to the field of can sealing machine technology, and in particular to a can sealing machine testing device. Background Technology
[0002] A can sealing machine inspection device is an automated equipment used to inspect the quality of cans after they have been sealed by the can sealing machine. Its core function is to use a variety of technical means to identify defects that may occur in the can during the sealing process in real time and accurately, thereby ensuring the sealing performance, appearance quality and safety of the product. It is an indispensable quality control link in the pharmaceutical production line.
[0003] Taking the precision positioning structure as an example, when the tank is transported, the motor drives the rotating rod to rotate, which in turn drives the connecting rod. The fixed shaft on the connecting rod drives the upper and lower clamping plates to retract inward through the slide bar, clamping the tank. Then the cover is put on. After the cover is put on, the drive motor drives the entire structure to stretch outward, transporting the installed tank out.
[0004] Inaccurate positioning of a can-sealing machine detection device can lead to misalignment of the device with the can's sealing area, resulting in deviations in the sealing performance test. For example, it may miss micro-gap areas or incomplete seals at the can opening, causing substandard sealed cans to flow into subsequent stages. Ultimately, this can cause the medicine to become damp, contaminated, or deteriorate, affecting its stability and efficacy. Medicines have extremely high requirements for sealing; substandard sealing can lead to microbial contamination and volatile components. If these substandard products enter the market and are used by patients, it can cause medication safety incidents, threatening patients' health and exposing companies to regulatory penalties and legal risks. Therefore, a can-sealing machine detection device is proposed to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1 to 2This utility model provides an embodiment comprising a conveyor belt 1, with fixed plates 2 fixedly connected to both the front and rear sides of the conveyor belt 1. The fixed plates 2 are securely connected to the support of the conveyor belt 1 by welding. Through their rigid structure, they drive the conveyor belt 1 to maintain a straight and stable shape, thereby limiting the lateral displacement of the conveyor belt 1 to prevent it from deviating during operation and ensuring the accuracy of the tank conveying path. Bases 3 are fixedly connected to the bottom of both fixed plates 2. The bases 3 have a large bottom area, providing solid support and ensuring the entire device stands stably on the work site. This enhances the overall stability of the device, preventing vibration from affecting the tank conveying and processing accuracy. A support plate 4 is fixedly connected to the top of the base 3. The support plate 4 is vertically welded to the base 3 and has a certain height and strength. Through its upward extension structure, it drives the upper extension plate 5, motor 6, and other components to a suitable working height, thereby providing reliable vertical support to support the weight of the equipment above and maintain the normal operation of the device. The support plate 4 has an extension plate 5 fixedly connected to its left side. The extension plate 5 is bolted to the side of the support plate 4 and extends horizontally towards the conveyor belt 1. By expanding the installation space, the motor 6 extends to a suitable position directly above the conveyor belt 1. Through a reasonable layout design, the motor 6 is provided with an installation platform to facilitate its driving of the main shaft 7 to operate the tank. The motor 6 is fixedly connected to the top of the extension plate 5 and fastened to the extension plate 5 with bolts. By converting electrical energy into rotational power, the motor 7 drives the main shaft 7 to rotate at high speed according to the set speed and torque. Through stable power output, the motor 6 provides the core driving force for the capping and assembly operations of the tank. The drive end of the motor 6 is fixedly connected to the main shaft 7. The main shaft 7 and the drive end of the motor 6 are tightly connected through a coupling. By transmitting the rotational power output by the motor 6, the assembly column 8 connected at the lower end rotates synchronously and stably. Through precise power transmission, the assembly column 8 can accurately perform capping, clamping and other actions.
[0026] A mounting column 8 is fixedly connected to the bottom of the main shaft 7. The mounting column 8 is a hollow columnar structure, fixed to the lower end of the main shaft 7 by welding. By receiving the rotational motion transmitted by the main shaft 7, it drives the internally installed cylinder 9, gripper 11, and other components to rotate together. Then, by acting as a carrier of the actuator, it achieves the effect of transmitting power to the end effector, realizing the processing operation of the tank. The cylinder 9 is fixedly connected to the inside of the mounting column 8. The cylinder 9 is bolted to the inner wall of the mounting column 8. By connecting to a compressed air pipeline, the gas pressure generates a telescopic motion, driving the top-connected pad 10 to move up and down vertically. Then, by precisely controlling the telescopic stroke and speed of the cylinder 9, the gripper 11 is driven to clamp. To tighten or loosen the can, a pad 10 is fixedly connected to the top of the cylinder 9. The pad 10 is a flat metal plate and is connected to the top of the piston rod of the cylinder 9 by bolts. By evenly distributing the thrust generated by the cylinder 9, multiple grippers 11 are driven to rise and fall synchronously and smoothly. Through stable force transmission, the grippers 11 can reliably hold the can and avoid uneven force causing the can to slip. Multiple rotating shafts 12 are fixedly connected to the inner wall of the assembly column 8. The multiple rotating shafts 12 are evenly distributed on the inner wall of the assembly column 8. Synchronous lifting and centripetal movement are achieved by the rotation of the rotating shafts 12. Then, through the enveloping effect when clamping, the can is firmly gripped to complete the purpose of screwing on the cap, handling and other operations.
[0027] Multiple rotating shafts 12 are rotatably connected to grippers 11 on their exterior. The rotating shafts 12 are mounted on the hinged parts of the grippers 11 via bearings. Through their own rotational characteristics, the grippers 11 can adaptively adjust their angle when clamping the can. This flexible rotational freedom allows the grippers 11 to tightly fit the can walls of different shapes and sizes, improving clamping stability and versatility. Precision positioning components are fixedly connected to the inner sides of multiple fixing plates 2. These components consist of mechanical limiting structures and are bolted to the inner sides of the fixing plates 2. Anti-collision springs 25 are fixedly connected to the tops of multiple grippers 11. These anti-collision springs 25 are compression springs, with one end welded to the top of the gripper 11 and the other end fixed to the inner wall of the assembly column 8. Through their elastic deformation capability, they drive the grippers 11... 1. When subjected to external impact, a buffer displacement is generated, and then the collision energy is absorbed to prevent the gripper 11 from rigidly colliding with the tank or other components, thus protecting the device and the tank from damage. The tops of multiple anti-collision springs 25 are fixedly connected to the inside of the assembly column 8. The inner wall of the assembly column 8 provides a fixed support point for the anti-collision springs 25. By limiting the displacement direction of the springs, the anti-collision springs 25 can stably play a buffering role. Then, through reasonable structural design, the reliability of the device operation and the service life can be enhanced. Multiple sliding grooves 26 are opened inside the assembly column 8. The sliding grooves 26 are formed on the inner wall of the assembly column 8 by machining. This allows the gripper 11 to reliably complete the clamping and releasing action of the tank, improving the accuracy of the sealing operation.
[0028] Reference Figures 3 to 5 The precision positioning component includes multiple sliders 13, each employing a high-precision linear optical axis. These sliders are fixed to the inner side of the fixing plate 2 via welding, and their smooth cylindrical surfaces provide a stable linear motion track for the sliders 14. Multiple sliders 14 are slidably connected to the exterior of each slider 13. Linear bearings are embedded within each slider 14, forming a sliding pair with the sliders 13. The rolling of the bearing balls and the low frictional resistance enable the sliders 14 to slide quickly and smoothly along the sliders 13. Each slider 14 is fixedly connected to an upper clamping plate 15, which is bolted to the slider 14. The rigid structure, by following the movement of the slider 14, achieves the effect of limiting and fixing the upper surface of the tank. The bottom of each slider 14 is fixedly connected to a lower clamping plate 16, which is also connected to the slider 14 by bolts, forming an upper and lower clamping structure with the upper clamping plate 15. Then, by moving synchronously, the tank is accurately positioned from the top and bottom. Each adjacent side of the lower clamping plate 16 is fixedly connected to a clamp 19. The clamp 19 is made of elastic rubber and is installed on the lower clamping plate 16 by bolts. Through the soft clamping surface, it adaptively conforms to the side of the tank, thus preventing scratches on the tank during positioning and providing reliable friction.
[0029] Each of the multiple lower clamping plates 16 has a fixed shaft 20 fixedly connected inside. The fixed shaft 20 is installed in the shaft hole of the lower clamping plate 16 by interference fit. Through its fixed state, it provides a rotation fulcrum for the connecting rod 21, thus forming the basis of the linkage transmission mechanism. Each of the multiple fixed shafts 20 has a connecting rod 21 fixedly connected to its exterior. One end of the connecting rod 21 is keyed to the fixed shaft 20, and the other end is hinged to the rotating shaft 22. Through the lever principle, the rotational motion of the rotating shaft 22 is converted into the linear motion of the slider 14. The other end of each rod 21 is rotatably connected to a rotating shaft 22. The rotating shaft 22 is mounted on the frame via a deep groove ball bearing, forming a rotating pair with the connecting rod 21. Through its own rotational freedom, it transmits the rotation of the rotating rod 23 to the connecting rod 21, thereby achieving the effect of force and motion conversion. Multiple rotating shafts 22 are externally fixedly connected to rotating rods 23. The rotating rods 23 are connected to the rotating shafts 22 via flat keys and driven to rotate by motor 18. In turn, they drive the rotating shafts 22 to rotate synchronously, thereby providing power to the entire positioning mechanism.
[0030] A drive shaft 24 is fixedly connected internally to the rotating rod 23. The drive shaft 24 is welded to the rotating rod 23. By transmitting the torque of the motor 18, the rotating rod 23 is rotated, thus driving the positioning mechanism. Multiple fixed shafts 20 are externally fixedly connected to fixed rings 28. The fixed rings 28 are installed on the fixed shafts 20 using a heat-shrink process. By limiting the axial displacement of the connecting rod 21, the motion accuracy of the linkage mechanism is ensured, thereby improving positioning stability. One limiting ring 17 is fixedly connected to the top of the drive shaft 24, and another limiting ring 17 is fixedly connected to the bottom of the drive shaft 24. The two limiting rings 17 are connected by threads. Installed at both ends of the drive shaft 24, the axial movement of the rotating rod 23 is restricted, thereby ensuring rotational accuracy and thus achieving accurate positioning. A second motor 18 is fixedly connected to the bottom of the drive shaft 24. The second motor 18 is rigidly connected to the drive shaft 24 through a coupling. By outputting rotational power, it drives the drive shaft 24 to rotate, thus providing a power source for the entire precision positioning assembly. The bottom of the second motor 18 is fixedly connected to the top of the base 3. The second motor 18 is fastened to the base 3 with bolts. Through the stable support of the base 3, the stability of the second motor 18 during operation is ensured, thereby ensuring a smooth and reliable power output of the positioning assembly.
[0031] Working principle: When the conveyor belt 1 smoothly transports the can to be processed to the designated station, the motor 6 receives the signal and drives the main shaft 7 to start rotating precisely. The main shaft 7 drives the assembly column 8 to operate synchronously through the transmission structure, providing stable power for the subsequent capping action. At the same time, the cylinder 9 quickly pushes upward, which is transmitted to the gripper 11 through the connecting rod, so that the gripper 11 slides smoothly along the slide groove 26, accurately wrapping around the side wall of the can and achieving a firm grip, preventing the can from shifting or shaking during the capping process. While the gripper fixes the can, the main shaft 7 continues to rotate and drives the capping mechanism downward, accurately aligning the can cap with the can body and completing the tightening operation. After the capping is completed, the cylinder 9 immediately returns to its downward position, and the gripper 11 resets upward along the slide groove 26 and releases the can body. The can body is then transported to the next stage by the conveyor belt 1.
[0032] When the can is transported to the capping station by conveyor belt 1, motor 218 starts and drives rotating rod 23 to rotate. Rotating rod 23 drives connecting rod 21 to retract inward through rotating shaft 22. The other end of connecting rod 21 is connected to fixed shaft 20. Under the action of contraction force, fixed shaft 20 drives upper clamping plate 15 and lower clamping plate 16 to slide smoothly inward along slide bar 14. The clamp 19 connected to the bottom of lower clamping plate 16 moves synchronously and precisely fits the side wall of the can, firmly fixing it in the preset position of the conveyor belt. This avoids misalignment of the cap due to can displacement during capping. After the capping process is completed, motor 21 rotates in reverse, driving rotating rod 23 and connecting rod 21 to stretch outward. Upper clamping plate 15 and lower clamping plate 16 reset along slide bar 14. Clamp 19 releases the can, allowing it to be smoothly transported to the next stage by the conveyor belt.
