Description

Technical Field

[0001] This utility model relates to the field of packaging container manufacturing technology, specifically to a bottom-mounted coiled stamping structure for can bodies. Background Technology

[0002] In the field of packaging container manufacturing, especially in the production of metal cans (such as aluminum cans and iron cans), the connection structure between the can body and the can bottom is crucial. Traditional methods for connecting the can body and the can bottom often involve welding, riveting, or threaded connections, but these methods have certain limitations in terms of production efficiency, cost control, and finished product quality.

[0003] First, while welding provides high connection strength, it is prone to thermal deformation during the process, affecting the overall aesthetics and dimensional accuracy of the tank. Furthermore, the fumes and spatter generated during welding pollute the production environment. In addition, welding equipment has high maintenance costs and relatively slow welding speeds, making it unsuitable for large-scale production.

[0004] Secondly, while riveting is simple to operate, the riveting points are prone to becoming stress concentration points, reducing the overall strength of the tank. Furthermore, the noise and vibration generated during riveting pose a potential threat to the health of operators. Additionally, the use of riveted components increases material costs.

[0005] Threaded connections are primarily suitable for tanks used in special applications, such as those requiring frequent disassembly and cleaning. However, for most disposable metal cans, the complexity and high cost of threaded connections are clearly unnecessary.

[0006] To overcome the shortcomings of traditional connection methods, automated tank body and bottom fastening technology has emerged in recent years. This technology uses a mechanical device to fasten the tank body and bottom together under certain pressure, forming a tight and robust connection structure without the need for additional welding, riveting, or threaded connections. This fastening structure not only improves production efficiency and reduces production costs but also reduces environmental and noise pollution during the production process. Furthermore, since no heat processing is involved in the fastening process, it avoids the impact of thermal deformation on the dimensional accuracy and aesthetics of the tank. Summary of the Invention

[0007] In order to overcome the shortcomings of existing technical solutions, this utility model provides a tank body bottom coil stamping structure, which can effectively solve the problem of low efficiency in the connection method between the tank body and the tank bottom mentioned in the background technology.

[0008] The technical solution adopted by this utility model to solve its technical problem is: a tank body bottom-mounted coiled stamping structure, including: A frame plate is provided below which a chain steering device with its movable end facing upward is provided. The movable end of the chain steering device passes through the frame plate and is fixedly connected to one end of the crankshaft. The curved section of the crankshaft is movably connected to one end of the transmission rod via a hinge, and the other end of the transmission rod is fixedly connected to the mounting plate. A pressure head is fixedly installed on the upper surface of the mounting plate. The top of the pressure head has a filling port for the bottom plate of the tank to enter. A discharge trough is provided above the mounting plate, and the lower outlet of the discharge trough corresponds to the position of the filling port. A movable plate is provided on the rear side of the mounting plate, and a slider is fixedly connected to the lower surface of the movable plate. A second frame is fixedly installed on the frame plate, and a slide rail is installed on the second frame. The slider slides in cooperation with the slide rail, so that the movable plate reciprocates along the second frame in a straight line.

[0009] Furthermore, a fixing plate is fixedly connected to the rear side of the second frame, and a circular groove is opened on the fixing plate. The other end of the crankshaft is installed in the circular groove through a bearing.

[0010] Furthermore, the chain steering gear is installed vertically, with its rotor output shaft directly fixedly connected to the crankshaft.

[0011] Furthermore, it also includes a vibratory feeder and a base for supporting the vibratory feeder, wherein the discharge port of the vibratory feeder is connected to the discharge trough via a slide.

[0012] Furthermore, it also includes a first frame on which a rotatable shaft is mounted. A first toothed disc is fixedly sleeved on the shaft, and a second toothed disc is fixedly sleeved on the input shaft of the chain steering gear. The first toothed disc and the second toothed disc are connected by a chain drive, and power is transmitted to the chain steering gear through the shaft via the chain drive.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model relates to a tank bottom coil stamping structure, which achieves efficient production and high-quality assurance through optimized structural design. In the tank bottom processing section, a chain steering mechanism drives the crankshaft and transmission rod, causing the mounting plate to move back and forth, allowing the pressure head and discharge chute to flexibly process and replenish material to the tank bottom. The pressure head ensures a tight fit between the tank bottom and the tank body, while the filling port design improves processing efficiency. The movable connection between the column and the second frame forms a stable sliding structure, ensuring the stability and directional accuracy of the mounting plate during movement, improving processing precision, extending equipment life, and reducing errors and damage.

Detailed Implementation

[0016] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0017] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0018] like Figure 1-4 As shown, the tank body bottom coil stamping structure 2 includes: The frame plate 33 has a chain guide 21 with its movable end facing upward below it. The movable end of the chain guide 21 passes through the frame plate 33 and is fixedly connected to one end of the crankshaft 22. The bent section of the crankshaft 22 is movably connected to one end of the transmission rod 23 via a hinge, and the other end of the transmission rod 23 is fixedly connected to the mounting plate 24. A pressure head 26 is fixedly installed on the upper surface of the mounting plate 24. The top of the pressure head 26 is provided with a feeding port 29 for the bottom plate of the tank to enter. A discharge trough 27 is provided above the mounting plate 24. The lower outlet of the discharge trough 27 corresponds to the position of the feeding port 29. A movable plate 32 is provided on the rear side of the mounting plate 24. A slider 31 is fixedly connected to the lower surface of the movable plate 32. A second frame 25 is fixedly installed on the frame plate 33. A slide rail 28 is installed on the second frame 25. The slider 31 slides in cooperation with the slide rail 28, so that the movable plate 32 moves back and forth in a straight line along the second frame 25.

[0019] The frame plate 33 serves as the base for the entire tank body bottom coil stamping structure 2, providing a stable mounting surface and support for the various components set above and below it, ensuring that the entire structure maintains a relatively fixed position during operation without shaking or displacement, thereby guaranteeing the accuracy and quality of processing.

[0020] The chain steering gear 21 is located below the frame plate 33, and its movable end passes through the frame plate 33 and connects to the crankshaft 22. The frame plate 33 provides the necessary space and structural support for this connection, enabling the chain steering gear 21 to work normally and transmit power to the crankshaft 22.

[0021] The chain steering mechanism 21 receives external power input and changes the direction of power transmission through its internal transmission mechanism, transmitting the motion of its moving end to the crankshaft 22. This steering function enables power to be transmitted to subsequent transmission components according to design requirements, achieving complex motion transformations and providing the power foundation for the entire tank bottom coil stamping structure 2. The chain steering mechanism 21 can adjust the output speed and torque, controlling the rotation speed and force of the crankshaft 22 according to the actual needs of tank bottom sheet conveying and processing, thereby achieving control over the rhythm and force of the entire processing process.

[0022] The crankshaft 22 converts the rotational motion transmitted by the chain steering gear 21 into irregular reciprocating motion. Its curved section design allows the point connected to the transmission rod 23 to undergo a complex up-down and left-right motion during rotation. This motion is transmitted to the mounting plate 24 via the transmission rod 23, thereby driving components such as the pressure head 26 on the mounting plate 24 to perform specific processing actions. This satisfies the different motion requirements during the processing of the can bottom sheet. The crankshaft 22 can rationally distribute the power of the chain steering gear 21 to the transmission rod 23 and the mounting plate 24, ensuring that all components work together to achieve the conveying and processing of the can bottom sheet.

[0023] The transmission rod 23 is movably connected to the bent section of the crankshaft 22 via a hinge, and its other end is fixedly connected to the mounting plate 24. Its function is to accurately transmit the irregular reciprocating motion of the crankshaft 22 to the mounting plate 24, so that the mounting plate 24 can move according to a predetermined trajectory and manner, ensuring that components such as the pressure head 26 can correctly process the bottom plate of the tank.

[0024] The transmission rod 23 serves to connect the crankshaft 22 and the mounting plate 24, and at the same time bears and transmits the force generated during the movement to a certain extent, providing stable support for the movement of the mounting plate 24 and ensuring the smoothness and reliability of the movement.

[0025] Mounting plate 24 serves as the mounting carrier for key processing components such as pressing head 26, providing these components with a fixed position and stable support. This ensures that they maintain the correct relative position and posture during operation, guaranteeing the processing accuracy of the can bottom sheet. Driven by transmission rod 23, mounting plate 24 reciprocates, thereby driving components such as pressing head 26 to perform processing actions such as conveying and pressing the can bottom sheet. It is a crucial link in the motion execution process throughout the entire processing.

[0026] The pressure head 26 is a component that directly processes the bottom sheet of the can. It receives the bottom sheet falling from the discharge trough 27 through the feeding port 29 at its top, and then uses its own pressure and movement to perform processing operations such as pressing and shaping on the bottom sheet, realizing the transformation of the bottom sheet from raw material to finished product. The shape and size of the pressure head 26 determine the final processed shape and size of the bottom sheet. Different shapes of pressure heads 26 can be designed according to different processing requirements to meet diverse production needs.

[0027] The feeding port 29 provides a channel for the can bottom sheet to enter the pressing head 26, allowing the can bottom sheet to fall accurately into the processing position of the pressing head 26 and ensuring the smooth progress of the processing. Its position and size design need to match the lower outlet of the discharge chute 27 to ensure that the can bottom sheet can enter the feeding port 29 smoothly and accurately.

[0028] The discharge trough 27 is used to store the can bottom sheets to be processed, and conveys the can bottom sheets one by one or in a certain pattern to the feeding port 29 of the pressure head 26 through its lower outlet. The design of the discharge trough 27 can ensure the orderly supply of can bottom sheets, avoid material accumulation or chaos, and improve processing efficiency and product quality.

[0029] The movable plate 32 is located behind the mounting plate 24 and slides along the slide rail 28 on the second frame 25 via the slider 31, enabling it to reciprocate linearly along the second frame 25. It provides additional support for the can bottom sheet during transport and processing, preventing it from shifting or deforming during movement. It can also participate in auxiliary processing operations such as positioning and clamping. The movement of the movable plate 32 coordinates with the movement of the mounting plate 24 to jointly complete the transport and processing of the can bottom sheet.

[0030] The slider 31 is fixed to the lower surface of the movable plate 32 and slides in engagement with the slide rail 28 mounted on the second frame 25, providing precise guidance for the linear reciprocating motion of the movable plate 32. This ensures that the movable plate 32 always moves along the predetermined trajectory during movement without deviation or jamming, guaranteeing the smoothness and accuracy of the movement. The engagement between the slider 31 and the slide rail 28 uses low-friction materials and a design that reduces friction during movement, lowers energy loss, extends the service life of components, and also helps improve the sensitivity and response speed of the movable plate 32's movement.

[0031] The second frame 25 provides a stable mounting base for the slide rail 28. At the same time, through its connection with the frame plate 33, it connects the movable plate 32 and other related components with the entire tank bottom coil stamping structure 2 into a whole, enhancing the stability and rigidity of the structure and ensuring that each component can maintain a relatively fixed position and posture during operation. The second frame 25 restricts the movement range of the movable plate 32 to a certain extent, ensuring that the movable plate 32 can perform linear reciprocating motion within a safe area, preventing the movable plate 32 from colliding or interfering with other components due to excessive movement, and ensuring the safety and reliability of the entire processing process.

[0032] See Figure 2 and Figure 3 The second frame 25 is fixedly connected to a fixing plate 20 on the rear side. The fixing plate 20 has a circular groove 30. The other end of the crankshaft 22 is installed in the circular groove 30 through a bearing.

[0033] During operation, the crankshaft 22 is subjected to power from the chain steering gear 21 and various forces generated by its own transmission. The fixed plate 20 provides a stable support point for the other end of the crankshaft 22, forming a bidirectional constraint with the end of the crankshaft 22 connected to the chain steering gear 21. This allows the crankshaft 22 to maintain a relatively fixed position during operation, reducing swaying and offset caused by forces, thereby ensuring the stability of the entire tank bottom coil stamping structure 2. When the crankshaft 22 rotates, its various parts will bear different stresses. By installing the other end of the crankshaft 22 in the circular groove 30 of the fixed plate 20, the stress borne by the crankshaft 22 can be distributed to the fixed plate 20 and the second frame 25, avoiding stress concentration in a certain part of the crankshaft 22, reducing the risk of breakage or damage to the crankshaft 22 due to stress concentration, and extending the service life of the crankshaft 22.

[0034] See Figure 2 and Figure 3 The chain steering gear 21 is installed vertically, and its rotor output shaft is directly fixedly connected to the crankshaft 22.

[0035] See Figure 1 It also includes a vibratory feeder 4 and a base 3 for supporting the vibratory feeder 4. The discharge port of the vibratory feeder 4 is connected to the discharge trough 27 via a slide 5.

[0036] The vibratory feeder 4, utilizing its unique disc structure and vibration principle, can automatically arrange the can bottom sheets. By adjusting the vibration frequency and amplitude of the vibratory feeder 4, the can bottom sheets are aligned in a specific direction and posture, ensuring neat edges and an upward-facing surface, preparing them for accurate subsequent conveying and processing. After being arranged, the can bottom sheets move orderly towards the discharge port along a preset track under the action of the vibratory feeder 4. This orderly output method ensures that the can bottom sheets enter the subsequent conveying system with a stable rhythm and regularity, avoiding problems such as uneven or intermittent feeding that may occur with manual feeding, thus improving the continuity and stability of the production process.

[0037] The vibratory feeder 4 can provide continuous 24-hour feeding without the need for frequent manual material addition. Compared with manual feeding, it greatly reduces downtime caused by manual operation, improves equipment utilization and production efficiency. The vibration of the vibratory feeder 4 enables the tank bottom plates to move and arrange rapidly on the plate surface, thus achieving a fast feeding speed.

[0038] See Figure 4 It also includes a first frame 1, on which a rotatable shaft 6 is mounted, and a first toothed disc 7 is fixedly sleeved on the shaft 6. A second toothed disc 9 is fixedly sleeved on the input shaft of the chain steering gear 21. The first toothed disc 7 and the second toothed disc 9 are connected by a chain 8. Power is transmitted to the chain steering gear 21 through the shaft 6 and the chain 8.
