Edge sealing apparatus for round tin cans

Abstract

This utility model relates to the field of tinplate drum technology, specifically a sealing device for a round tinplate drum. It includes a fixing mechanism comprising a rotating disc with clamping rods on its inner wall. The inner wall of the rotating disc is rotatably connected to the middle end of the clamping rods. An arc-shaped rod is provided on one side of each clamping rod, and one side of the clamping rod slidably contacts one end of the arc-shaped rod. This sealing device for round tinplate drums extends the length of the telescopic rod, causing the connecting rod and the arc-shaped rod to move synchronously. When the arc-shaped rod moves, external force is increased from one side of the clamping rods, gradually bringing the two clamping rods to a horizontal position and contacting the outer side of the middle end of the drum for a fixing effect. Subsequently, by starting the motor, the rotating disc rotates in stages, bringing the fixed drum below the sealing machine. This method prevents the drum from shifting due to the downward pressure of the sealing machine.

Description

Technical Field

[0001] This utility model relates to the field of tin bucket technology, specifically to a sealing device for round tin buckets. Background Technology

[0002] Tinplate drums are a common type of container widely used in various industries such as food, chemicals, and paint. The main material of these drums is tinplate, also known as tin-plated iron, a metal material with a layer of tin plated onto the surface of iron. Due to their excellent corrosion resistance, airtightness, and lightweight properties, tinplate drums have become the preferred packaging and storage containers for many businesses and households.

[0003] In existing technologies, when sealing tin drums, the sealing process is carried out in an automated production line. This process can achieve full automation of the entire process of feeding, sealing, and unloading the tin drums through continuous operation. By using precise mechanical control and real-time monitoring by sensors, the sealing efficiency and quality consistency can be greatly improved, while reducing errors and labor intensity caused by manual operation. However, the feeding method used is to cut multiple grooves on the disc for fitting and feeding. Although this can achieve the positioning effect, when subjected to the pressure of the edge sealing equipment, the disc and the iron drum only make point-to-surface contact through the grooves, resulting in poor force distribution. This can easily cause the iron drum to deform or shift under pressure, affecting the edge sealing accuracy. Therefore, we propose an edge sealing device for round tin drums. Utility Model Content

[0004] One of the technical problems this application aims to solve is to fix the iron drum immediately during feeding to prevent displacement of the iron drum when subjected to pressure.

[0005] To address the aforementioned technical problems, this application provides a sealing device for a round tin bucket, comprising a fixing mechanism, a closing mechanism at the top of the fixing mechanism, a rotating disc, a clamping rod on the inner wall of the rotating disc, the inner wall of the rotating disc being rotatably connected to the middle end of the clamping rod, an arc-shaped rod on one side of the clamping rod, the side of the clamping rod slidingly contacting one end of the arc-shaped rod, a connecting rod on one side of the arc-shaped rod, the side of the arc-shaped rod being fixedly connected to one end of the connecting rod, a side plate on the other end of the connecting rod, the other end of the connecting rod being fixedly connected to one side of the middle of the side plate, a telescopic rod on the inner side of the top of the side plate, the inner side of the top of the side plate being fixedly connected to one end of the telescopic rod, and the other end of the telescopic rod being fixedly connected to the inner side of the rotating disc.

[0006] In some embodiments, the closing mechanism includes a closing cover, a plug is provided on the bottom edge of the closing cover, the bottom edge of the closing cover is fixedly connected to the top end of the plug, the outer side of the plug is engaged with the inner wall of the rotating tray, and the top end of the rotating tray contacts the bottom edge of the closing cover.

[0007] In some embodiments, a grating sensor is provided at the bottom of the side plate, the bottom of the side plate is fixedly connected to one side of the grating sensor, a receiver is provided at the bottom of the grating sensor, and the bottom of the grating sensor and the top of the receiver are rotatably aligned.

[0008] In some embodiments, the receiver has a platform at its bottom end, the bottom end of the receiver is fixedly connected to the top side of the platform, and the top side of the platform is rotatably connected to the bottom end of the transfer tray.

[0009] In some embodiments, a motor is provided on the inner wall of the platform, and the inner wall of the platform is fixedly connected to the outer side of the motor. A fixed plate is provided at the output end of the motor, and the output end of the motor is fixedly connected to the bottom center of the fixed plate. One side of the fixed plate is fixedly connected to the inner side of the transfer tray. A controller is provided at the top center of the fixed plate, and the top center of the fixed plate is fixedly connected to the bottom end of the controller.

[0010] In some embodiments, one end of the clamping rod is provided with a spring, and one end of the clamping rod is fixedly connected to one end of the spring.

[0012] In some embodiments, a can sealing machine is provided on the top side of the platform, and the top side of the platform is fixedly connected to the connecting end of the can sealing machine.

[0013] This utility model has at least the following beneficial effects: 1. By extending the telescopic rod, the side plate moves a short distance, while the connecting rod and the arc rod move synchronously. When the arc rod moves, it increases the external force from one side of the clamping rod, gradually making the two clamping rods horizontal and contacting the outer side of the middle of the iron drum to achieve a fixing effect. Then, by starting the motor, the material transfer plate rotates in stages, bringing the fixed iron drum to the bottom of the sealing machine. In this way, the iron drum will not be displaced due to the downward pressure when it is subjected to the pressure of the sealing machine. 2. By aligning the closed cover vertically with the top of the transfer tray and fitting the insert rod into the transfer tray, the inner structure of the transfer tray is covered, thus enclosing and protecting the moving parts such as the clamping rod and arc rod inside the transfer tray. This prevents iron filings, oil stains, and other debris generated during the sealing process of the iron drum from falling into the mechanism, reducing component wear and the risk of failure. At the same time, the closed cover can also serve as a protective barrier to prevent operators from accidentally contacting the moving parts inside the transfer tray. Attached Figure Description

[0016] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a sealing device for a round tin bucket, including a fixing mechanism 1, a closing mechanism 2 at the top of the fixing mechanism 1, a rotating material tray 12, a clamping rod 13 on the inner wall of the rotating material tray 12, the inner wall of the rotating material tray 12 being rotatably connected to the middle end of the clamping rod 13, an arc-shaped rod 14 on one side of the clamping rod 13, the side of the clamping rod 13 being slidably in contact with one end of the arc-shaped rod 14, a connecting rod 15 on one side of the arc-shaped rod 14, and one side of the arc-shaped rod 14 being fixed to one end of the connecting rod 15. The connecting rod 15 has a side plate 16 at one end, which is fixedly connected to one side of the middle of the side plate 16. A telescopic rod 17 is located on the inner side of the top of the side plate 16, with one end fixedly connected to the inner side of the telescopic rod 17. The other end of the telescopic rod 17 is fixedly connected to the inner side of the transfer tray 12. A grating sensor 19 is located at the bottom of the side plate 16, with one side fixedly connected to the bottom of the grating sensor 19. A receiver 110 is located at the bottom of the grating sensor 19. The bottom end of the receiver 110 rotatably corresponds to the top end of the receiver 110. A platform 11 is provided at the bottom end of the receiver 110, and the bottom end of the receiver 110 is fixedly connected to the top side of the platform 11. The top side of the platform 11 is rotatably connected to the bottom end of the rotating tray 12. A motor 113 is provided on the inner wall of the platform 11, and the inner wall of the platform 11 is fixedly connected to the outer side of the motor 113. A fixed plate 112 is provided at the output end of the motor 113, and the output end of the motor 113 is fixedly connected to the center of the bottom side of the fixed plate 112. One side end of the fixed plate 112 is connected to the rotating tray. The inner side of the fixed plate 112 is fixedly connected. A controller 114 is provided at the center of the top side of the fixed plate 112. The center of the top side of the fixed plate 112 is fixedly connected to the bottom end of the controller 114. A spring 18 is provided at one end of the clamping rod 13. One end of the clamping rod 13 is fixedly connected to one end of the spring 18. A rubber pad 111 is provided on the inner side of one end of the clamping rod 13. The inner side of one end of the clamping rod 13 is fixedly connected to the outer side of the rubber pad 111. A can sealing machine 116 is provided on the top side of the platform 11. The top side of the platform 11 is fixedly connected to the connecting end of the can sealing machine 116.

[0017] When using this type of sealing equipment for round tin buckets, firstly, a rotating disc 12 is mounted on a platform 11, which can rotate on the platform 11. The rotating disc 12 has six notches that fit into the outer side of the tin bucket. Two clamping rods 13 are installed in each notch. The middle end of the clamping rods 13 can rotate within the inner wall of the rotating disc 12 via a connector. When the clamping rods 13 are not subjected to external force, they are in an inclined state. Then, an arc-shaped rod 14 is designed between the two clamping rods 13, which can slide on one side of the two clamping rods 13. A connecting rod 15 is fixed to one side of the arc-shaped rod 14, connecting... One end of the rod 15 is fixed to the middle of the side plate 16. Therefore, when the transfer plate 12 receives the iron drum, the extension rod 17 is extended to make the side plate 16 move a short distance. At the same time, the connecting rod 15 and the arc rod 14 move synchronously. When the arc rod 14 moves, it will increase the external force from one side of the clamping rod 13, so that the two clamping rods 13 gradually become horizontal and contact the outer side of the middle of the iron drum to achieve a fixing effect. Then, by starting the motor 113, the transfer plate 12 rotates in stages, so that the fixed iron drum comes to the bottom of the sealing machine 116. In this way, the iron drum is less likely to shake when subjected to the pressure of the sealing machine 116. Two receivers 110 are designed on the top side of the platform 11. When the transfer plate 12 moves in stages, the receiver 110 in the feeding direction first aligns vertically with the grating sensor 19. The controller 114 drives the telescopic rod 17 to move the side plate 16, connecting rod 15, and arc rod 14. The arc rod 14 pushes the clamping rod 13 from an inclined state to a horizontal state to fix the iron drum. After the iron drum rotates with the transfer plate 12 to the bottom of the sealing machine 116 and the edge is sealed, the transfer plate 12 continues to rotate. When the receiver 110 in the discharge direction aligns with the grating sensor 19, the controller 114 drives the telescopic rod 17 to retract. The clamping rod 13 loses external force and returns to an inclined state. The iron drum is discharged from the notch. The automatic control of fixing and discharging the iron drum is achieved through the cooperation of the receiver 110 and the grating sensor 19. A rubber pad 111 is designed on the clamping surface of the clamping rod 13. The rubber pad 111 contacts the iron bucket, making it less likely for the iron bucket to be scratched due to rigid contact during clamping. At the same time, the elastic deformation of the rubber pad 111 enhances the clamping friction, ensuring the stability of the iron bucket when it is fixed.

[0018] Example 2: Please refer to Figure 1-4 The closing mechanism 2 includes a closing cover 21. A rod 22 is provided on the bottom edge of the closing cover 21. The bottom edge of the closing cover 21 is fixedly connected to the top end of the rod 22. The outer side of the rod 22 fits and engages with the inner wall of the rotating material tray 12. The top end of the rotating material tray 12 contacts the bottom edge of the closing cover 21.

[0019] A closing cover 21 is installed on the top side of the platform 11. Multiple insert rods 22 are designed on the bottom edge of the closing cover 21. Therefore, by aligning the closing cover 21 vertically with the top of the transfer tray 12 and fitting the insert rods 22 into the transfer tray 12, the structure inside the transfer tray 12 is covered. This encloses and protects the moving parts such as the clamping rod 13 and the arc rod 14 inside the transfer tray 12, preventing iron filings, oil stains and other debris generated during the sealing process of the iron drum from falling into the mechanism, reducing component wear and the risk of failure. At the same time, the closing cover 21 can also serve as a protective barrier to prevent operators from accidentally contacting the moving parts inside the transfer tray 12, thereby improving the safety of equipment use.

[0020] Please see Figure 1-4 By extending the telescopic rod 17, the side plate 16 moves a short distance. Simultaneously, the connecting rod 15 and the arc-shaped rod 14 move synchronously. When the arc-shaped rod 14 moves, it increases external force from one side of the clamping rod 13, gradually bringing the two clamping rods 13 into a horizontal state and contacting the outer side of the middle of the iron drum to achieve a fixing effect. Then, by starting the motor 113, the rotating disc 12 rotates in stages, bringing the fixed iron drum below the sealing machine 116. This method prevents the iron drum from shaking when subjected to the pressure of the sealing machine 116. Furthermore, when the rotating disc 1... 2. During the phased movement, the receiver 110 in the feeding direction first aligns perpendicularly with the grating sensor 19. The controller 114 drives the telescopic rod 17 to move the side plate 16, which in turn moves the connecting rod 15 and the arc rod 14. The arc rod 14 pushes the clamping rod 13 from an inclined state to a horizontal state to fix the iron drum. After the iron drum rotates with the transfer plate 12 to the bottom of the sealing machine 116 and the edge is sealed, the transfer plate 12 continues to rotate. When the receiver 110 in the discharge direction aligns with the grating sensor 19, the controller 114 drives the telescopic rod 17 to retract. The clamping rod 13 loses external force and returns to an inclined state. The iron drum is discharged from the notch, realizing automated edge sealing. By aligning the closed cover 21 vertically with the top of the transfer tray 12 and fitting the insert rod 22 into the transfer tray 12, the inner structure of the transfer tray 12 is covered, thereby enclosing and protecting the moving parts such as the clamping rod 13 and the arc rod 14 inside the transfer tray 12, preventing iron filings, oil stains and other debris generated during the sealing process of the iron drum from falling into the mechanism.
