Description

Technical Field

[0001] This invention relates to the field of tank processing and sealing devices, and more specifically, to a metal tank processing, sealing, and shaping device. Background Technology

[0002] In the manufacturing process of metal cans, sealing the can opening is a crucial step in ensuring the can's airtightness and overall quality. Currently, the industry commonly uses a rolling pin to apply pressure to the can's flange, causing plastic deformation in the metal and thus achieving a tight seal at the can opening.

[0003] However, existing metal can sealing devices have many problems that urgently need to be solved. Current sealing operations mostly rely on mechanical control of the sealing device's movement distance to position the device relative to the can opening. But this purely mechanical control method is difficult to accurately adapt to differences in can material, thickness, and flange shape. Because the sealing force and fit cannot be flexibly adjusted according to actual conditions, insufficient adhesion between the metal parts often results in inadequate sealing.

[0004] When the metal seal is insufficient, unevenness can easily occur at the sealing point. This unevenness not only affects the appearance of the can, making its surface rough and reducing the product's aesthetics, but more seriously, it threatens the can's sealing performance. If the can is not properly sealed, the contents may leak during storage or transportation, leading to product loss or even safety accidents. This is especially true for cans containing liquids, flammable, explosive, or toxic and hazardous materials, where the consequences could be disastrous.

[0005] In summary, existing metal can sealing devices have significant shortcomings in terms of sealing accuracy, adaptability, and product quality assurance. Therefore, developing a metal can processing, sealing, and shaping device that can improve sealing stability, ensure a smooth seal, and possess good adaptability is of great practical significance and is crucial for improving the production quality and efficiency of metal cans. Summary of the Invention

[0006] The purpose of this invention is to provide a metal can processing, sealing, and shaping device to solve the problems mentioned in the background art.

[0007] A metal can processing, sealing, and shaping device includes an operating platform. An isolation baffle is fixedly installed on the upper side of the operating platform, and a main control box is fixedly installed on the side of the isolation baffle. A lifting platform is fixedly installed in the middle of the operating platform, and a third electric push rod is fixedly installed at the lower end of the lifting platform. A pair of mounting brackets are fixedly installed on both sides of the operating platform. A side baffle is provided at the upper end of the mounting bracket, and a connecting frame is provided on the inner side of the side baffle. A sliding limiter is fixedly installed at the upper end of the connecting frame.

[0008] A mounting column is fixedly installed on the upper rear side of the operating platform. A support frame is fixedly installed on the front middle of the mounting column. Connecting rods are fixedly installed on both sides of the support frame. Connecting parts are fixedly installed on the sides of the connecting rods. A stabilizing part is provided on the lower side of the connecting part. The lower end of the connecting part is snapped into the stabilizing part.

[0009] A positioning rod is provided in the middle of the stabilizer. One end of the positioning rod is fixedly connected to the fixing ring, and the other end of the positioning rod is provided with a limit sleeve. A constant force spring is fixedly installed between the limit sleeve and the positioning rod.

[0010] A sealing element is fixedly installed in the middle of the fixing ring, and a sealing head is fixedly installed at the lower end of the sealing element. Heat insulation boxes are fixedly installed on both sides of the fixing ring. Heating elements are fixedly installed on the inner side wall of the heat insulation box. A fixing base is provided on the side of the heat insulation box, and a shape memory alloy is provided between the fixing base and the fixing ring.

[0011] Furthermore, the upper end of the stabilizer is provided with a circular through groove, the lower end of the connector is inserted into the circular through groove at the upper end of the stabilizer, a shock-absorbing spring is fixedly installed between the upper end of the stabilizer and the connecting frame, a pair of guide rods are vertically arranged on both sides of the connecting frame at the positions of the shock-absorbing spring, and through grooves corresponding to the guide rods are provided on both sides of the stabilizer.

[0012] By adopting the above technical solution, the stabilizer is suspended in the middle of the connecting frame by a shock-absorbing spring. The guide rod can ensure that the stabilizer remains stable during up-and-down shaking. The suspended stabilizer can ensure that when the sealing head contacts the upper edge of the metal can, it can be automatically locked in the sealing position, thereby sealing the can.

[0013] Furthermore, an auxiliary fixing plate is fixedly installed in the middle of the isolation baffle, an auxiliary fixing component is fixedly installed at the lower end of the mounting bracket, circular through slots corresponding to the auxiliary fixing components are opened on both sides of the auxiliary fixing plate, a third electric push rod is fixedly installed on the upper side of the auxiliary fixing plate, and the upper output end of the third electric push rod is fixedly connected to the lifting platform.

[0014] By adopting the above technical solution, the lifting platform can be raised and lowered by the third electric push rod, thereby moving the metal can that is fixedly clamped in the middle of the adjusting fixture upward, so as to perform sealing and shaping processing on the upper end of the can.

[0015] Furthermore, the inner wall of the side baffle is vertically provided with a limiting groove, and a limiting sleeve is slidably provided inside the limiting groove. A circular groove corresponding to the positioning rod is opened in the middle of the limiting sleeve.

[0016] By adopting the above technical solution, one end of the positioning rod is inserted into the inside of the limiting sleeve. When the positioning rod moves up and down slightly, the limiting sleeve moves synchronously inside the limiting groove along with the positioning rod.

[0017] Furthermore, a vibration plate is fixedly installed on the upper side of the sealing component, and a pressure sensor is fixedly installed on the side of the sealing component above the vibration plate.

[0018] By adopting the above technical solution, when the sealing component is sealing and shaping the tank, if a large shaking occurs, the sealing component will cause the vibrating plate to swing. If the shaking is too large, the upper side of the vibrating plate will contact the pressure sensor, thereby triggering an audible alarm to remind the operator that the processing is abnormal.

[0019] Furthermore, three adjusting clamps are fixedly installed on the upper end of the lifting platform. The upper side of the adjusting clamps is a slidable fixed structure. A positioning platform is fixedly installed on the upper side of the mounting bracket. The side baffle and the positioning platform are fixedly connected through the positioning platform.

[0020] By adopting the above technical solution, three adjusting clamps can clamp and fix the metal can, thereby facilitating subsequent processing.

[0021] Furthermore, balance bars are fixedly installed on both sides of the support frame, and auxiliary limiting members are fixedly installed on the side of the sliding limiting member. A circular through groove corresponding to the balance bar is opened in the middle of the auxiliary limiting member.

[0022] By adopting the above technical solution, the balance bar can move horizontally through the auxiliary limiting component, thereby maintaining the stability of the sealing component when it moves horizontally.

[0023] Furthermore, the inner cavity of the side baffle is provided with sliding grooves on both sides corresponding to the fixed base, and a support base is fixedly installed at the lower end of the operating table.

[0024] By adopting the above technical solution, the fixed base can slide up and down inside the sliding groove.

[0025] Furthermore, a second electric push rod is fixedly installed on the upper side of the middle part of the support frame, a damping ring is fixedly installed in the middle part of the support frame, a pressure switch is fixedly installed on the lower output end of the second electric push rod, a first electric push rod is fixedly installed in the middle of the pressure switch, the first electric push rod is a rubber component, and the first electric push rod and the pressure switch constitute a pressure-sensitive device.

[0026] By adopting the above technical solution, the pressure switch can be moved downward as a whole by the second electric push rod, thereby allowing for fine adjustment of the position of the first electric push rod. The through-type damping ring can provide resistance to the pressure switch, keeping the lower first electric push rod stable. When the pressure switch is subjected to pressure from the bottom, the pressure signal can be received through the main control box, which facilitates subsequent processing.

[0027] Furthermore, the main control box is equipped with a main control chip, and the main control box and the main control chip constitute a main control device. The sealing parts and sealing heads on both sides constitute a sealing device. The heat insulation box, heating element and fixed base constitute a sealing device. The fixing ring, shape memory alloy and fixed base constitute an interference fit device.

[0028] By adopting the above technical solution, the main control chip can receive signals from the pressure sensing device and control the start of the connecting rod, thereby sealing the metal can through the sealing device. At the same time, the heating device is activated, and the memory alloy inside the interference fit device returns to its original state, which can continuously provide appropriate force to the sealing device, thereby forming an interference fit between the sealing device and the metal can and improving the sealing effect.

[0029] Compared with the prior art, the advantages of this invention are:

[0030] 1. In this invention, by setting a positioning rod, a constant force spring can provide a stable thrust during the sealing process of metal cans, so that the sealing part can automatically match the sealing height within a certain range, and can quickly seal metal cans of different specifications.

[0031] 2. In this invention, by setting a structure with a heat insulation box, when the sealing head is attached to the upper sealing end of the tank for sealing, the instant heat memory alloy can provide additional interference force after the sealing head is attached to the tank, thereby enabling the tank to be processed.

[0048] An auxiliary fixing plate 14 is fixedly installed in the middle of the isolation baffle 4, and an auxiliary fixing component 13 is fixedly installed at the lower end of the mounting bracket 2. Circular through slots corresponding to the auxiliary fixing component 13 are opened on both sides of the auxiliary fixing plate 14. A third electric push rod 15 is fixedly installed on the upper side of the auxiliary fixing plate 14. The upper output end of the third electric push rod 15 is fixedly connected to the lifting platform 12. The lifting platform 12 can be raised and lowered by the third electric push rod 15, so that the metal can body fixedly clamped in the middle of the adjusting clamp 11 can be moved upward, thereby sealing and shaping the upper end of the can body.

[0049] A limiting groove 35 is vertically provided on the inner side wall of the side baffle 1. A limiting sleeve 28 is slidably provided inside the limiting groove 35. A circular groove corresponding to the positioning rod 27 is opened in the middle of the limiting sleeve 28. One end of the positioning rod 27 is inserted into the inside of the limiting sleeve 28. When the positioning rod 27 moves up and down slightly, the limiting sleeve 28 moves synchronously inside the limiting groove 35 with the positioning rod 27.

[0050] A vibrating plate 16 is fixedly installed on the upper side of the sealing component 18. A pressure sensor 1801 is fixedly installed on the side of the sealing component 18 above the vibrating plate 16. When the sealing component 18 seals and shapes the tank, if a large shaking occurs, the sealing component 18 will drive the vibrating plate 16 to swing. If the shaking is too large, the upper side of the vibrating plate 16 will contact the pressure sensor 1801, thereby triggering an audible alarm to remind the operator that there is an abnormality in the processing.

[0051] Three adjusting clamps 11 are fixedly installed on the upper end of the lifting platform 12. The upper side of the adjusting clamps 11 is a sliding fixed structure. A positioning platform 7 is fixedly installed on the upper side of the mounting bracket 2. The side baffle 1 and the positioning platform 7 are fixedly connected through the positioning platform 7. The three adjusting clamps 11 can clamp and fix the metal tank, thereby facilitating subsequent processing.

[0052] Balance bars 30 are fixedly installed on both sides of the support frame 9, and auxiliary limiting members 29 are fixedly installed on the side of the sliding limiting member 23. A circular through groove corresponding to the balance bar 30 is opened in the middle of the auxiliary limiting member 29. The balance bar 30 can move horizontally through the auxiliary limiting member 29, so as to keep the sealing member 18 moving stably when it moves horizontally.

[0053] The inner cavity of the side baffle 1 is provided with sliding grooves 34 corresponding to the fixed base 33 on both sides. The lower end of the operating table body 3 is fixedly installed with a support base 5. The fixed base 33 can slide up and down inside the sliding groove 34.

[0054] A second electric push rod 8 is fixedly installed on the upper side of the middle part of the support frame 9. A damping ring 803 is fixedly installed in the middle of the support frame 9. A pressure switch 801 is fixedly installed at the lower output end of the second electric push rod 8. A first electric push rod 802 is fixedly installed in the middle of the pressure switch 801. The first electric push rod 802 is a rubber component. The first electric push rod 802 and the pressure switch 801 form a pressure sensing device. The pressure switch 801 can be moved downward as a whole by the second electric push rod 8, so that the position of the first electric push rod 802 can be finely adjusted. The through-type damping ring 803 can provide resistance to the pressure switch 801, so that the first electric push rod 802 on the lower side remains stable. When the pressure switch 801 is subjected to pressure from the bottom, the pressure signal can be received through the main control box 401, which facilitates subsequent processing.

[0055] The main control box 401 contains a main control chip. The main control box 401 and the main control chip together form the main control device. The sealing parts 18 on both sides and the sealing head 19 together form the sealing device. The heat insulation box 20, the heating element 32 and the fixed base 33 together form the sealing device. The fixing ring 17, the shape memory alloy 31 and the fixed base 33 together form the interference fit device. The main control chip can receive the signal from the pressure sensing device. At the same time, the main control chip can control the start of the connecting rod 10, so that the metal can is sealed by the sealing device. During the process, the heating device is started, and the shape memory alloy 31 inside the interference fit device returns to its original state, which can continuously provide appropriate force to the sealing device, so that the sealing device and the metal can form an interference fit and improve the sealing effect.

[0056] Working principle of the invention: The operator places the metal can on the three adjusting clamps 11 on the upper end of the lifting platform 12. The upper side of these three adjusting clamps 11 is a sliding fixed structure, which can firmly fix the metal can and provide a stable foundation for subsequent processing. The main control box 401 controls the third electric push rod 15 to start. The third electric push rod 15 will push the lifting platform 12 upward as a whole until the top of the metal can contacts the first electric push rod 802, so that the upper end of the can reaches the appropriate sealing and shaping position. At this time, the first electric push rod 802 is subjected to upward force and triggers the pressure switch 801. The support frame 9 in the middle of the front side of the mounting column 6 is connected to the connecting parts 24 on both sides by connecting rods 10. The lower end of the connecting parts 24 is snapped into the stabilizer 2101. One end of the positioning rod 27 in the middle of the stabilizer 2101 is fixed to the fixing ring 17, and the other end is inserted into the limiting tube sleeve 28. A constant force spring 26 is provided between the two. At the same time, the stabilizer 2101 is suspended in the connecting frame 2 by the shock absorption spring 22. In the middle of the connecting frame 21, the guide rods 25 vertically arranged on both sides pass through the corresponding through slots on both sides of the stabilizer 2101. The horizontal movement of the connecting member 24 can be controlled by the connecting rod 10, thereby controlling the sealing member 18 to move closer to the metal can. When the sealing head 19 contacts the upper edge of the metal can, the suspended structure of the stabilizer 2101 and the shock-absorbing spring 22 can make the sealing head 19 adaptively lock in the sealing position. The guide rods 25 ensure the stability of the stabilizer 2101 during the up and down shaking process and ensure the accuracy of the sealing operation. The limiting sleeve 28 is slidably set in the limiting slide groove 35 on the inner side wall of the side baffle 1. When the positioning rod 27 shakes slightly up and down, the limiting sleeve 28 will shake synchronously in the limiting slide groove 35, further assisting in stabilizing the position of the sealing member 18. The balance rods 30 fixed on both sides of the support frame 9 pass through the corresponding circular through slots in the middle of the auxiliary limiting member 29 on the side of the sliding limiting member 23. When the sealing member 18 moves horizontally, the balance rods 30 can maintain the stability of its movement.

[0057] The sealing component 18 installed in the middle of the fixing ring 17 is connected to the sealing head 19 at its lower end. Under the control of the main control chip in the main control box 401, the sealing device is driven by the connecting rod 10 to perform sealing processing on the metal can. The vibration plate 16 installed on the upper side of the sealing component 18 and the pressure sensor 1801 located on the upper side of the vibration plate 16 together constitute a monitoring structure. If the sealing component 18 causes a large shaking when sealing and shaping the can, the sealing component 18 will drive the vibration plate 16 to swing. If the shaking is too large, the upper side of the vibration plate 16 will contact the pressure sensor 1801, thereby triggering an audible alarm to remind the operator that the processing is abnormal.

[0058] Heating elements 32 are installed on the inner walls of the heat insulation box 20 on both sides of the fixing ring 17. A shape memory alloy 31 is set between the fixing base 33 on the side of the heat insulation box 20 and the fixing ring 17. Together, they form an interference fit device and a sealing device. When the sealing head 19 is in contact with the can opening, the constant force spring 26 is in its natural state. When the sealing head 19 is in contact with the can opening, the constant force spring 26 is pushed and compressed by the pressure at the metal can opening. At this time, the shape memory alloy 31 absorbs the pressure and deforms. During the sealing process, the heating elements 32 are activated, which restores the shape memory alloy 31 to its original state, thereby generating a force in the direction of the metal can. This continuously provides a suitable force to the sealing device, so that the sealing device and the metal can form an interference fit, improve the sealing effect, and ensure the sealing performance of the can.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
