[0028] Referring to Figures 1 and 2, a stainless steel kettle trimming device according to this utility model includes a machine base 100, a rotating device, a pressing device, and a cutting device. The rotating device includes a first frame 210, a driving shaft 220, a driven shaft 230, and a first drive mechanism. The first frame 210 is fixedly connected to the machine base 100. The driving shaft 220 is horizontally arranged and rotatably connected to the first frame 210. One end of the driving shaft 220 is fixedly connected to a first flange 240. The first drive mechanism is connected to the other end of the driving shaft 220 and can drive the driving shaft 220 to rotate. The driven shaft 230 is used to mount stainless steel kettles and has different specifications. One end of the driven shaft 230 is fixedly connected to a second flange 250. The first flange 240 and the second flange 250 are detachably fixedly connected by bolts. The pressing device is used to press the stainless steel kettle onto the driven shaft 230. The cutting device is used to cut the stainless steel kettle.

[0029] It is understood that the stainless steel kettle trimming device provided in this embodiment of the invention, through the detachable connection between the first flange 240 and the second flange 250, facilitates the quick replacement and adjustment of driven shafts 230 with different diameters, thereby adapting to stainless steel kettles with different inner diameters. This greatly improves the versatility and flexibility of the equipment and reduces equipment investment costs. The first drive mechanism drives the active shaft 220 to rotate, which in turn drives the driven shaft 230 and the stainless steel kettle to rotate synchronously. Cutting is performed while rotating, resulting in more uniform and stable cutting with smooth, burr-free edges, improving the product's appearance quality and dimensional accuracy. Simultaneously, a clamping device presses the stainless steel kettle firmly onto the driven shaft 230, preventing displacement or vibration during rotation and cutting, thus effectively ensuring trimming quality and reducing the scrap rate.

[0030] Further, referring to Figures 1 and 2, according to some embodiments of the present invention, the pressing device includes a second frame 310, a second drive mechanism, and a pressure plate 320. The second frame 310 is fixedly connected to the machine base 100, and the second drive mechanism is mounted on the second frame 310. The second drive mechanism is connected to the pressure plate 320 and can drive the pressure plate 320 to move toward the end of the driven shaft 230 to press the stainless steel kettle, or drive the pressure plate 320 away from the driven shaft 230.

[0031] Understandably, by setting up a second frame 310, a second drive mechanism, and a pressure plate 320, and enabling the second drive mechanism to move the pressure plate 320 toward or away from the end of the driven shaft 230, automatic clamping and releasing of the stainless steel kettle is achieved, effectively improving clamping efficiency and processing stability. This structure not only enhances the automation level of the equipment but also ensures that the stainless steel kettle does not shift or loosen during the cutting process, thereby guaranteeing the consistency of cutting quality and the yield rate.

[0032] Furthermore, referring to Figures 1 and 2, according to some embodiments of the present invention, the pressing device further includes a connecting seat 330, a pressure plate 320 is rotatably connected to one end of the connecting seat 330, and a second driving mechanism is connected to the other end of the connecting seat 330. The second driving mechanism can drive the connecting seat 330 to move closer to or away from the driven rotating shaft 230.

[0033] Understandably, the rotatable connection of the pressure plate 320 to the connecting seat 330 allows the pressure plate 320 to axially press the stainless steel pot while rotating with it when in contact with the end face of the stainless steel pot. This avoids damage to the surface of the stainless steel pot caused by friction due to rigid contact, thereby improving the flexibility and safety of clamping, and also helps to improve the stability and reliability of the pressing process.

[0034] Furthermore, referring to Figures 1 and 2, according to some embodiments of the present invention, the second drive mechanism includes a first cylinder 340, which is fixedly mounted on the second frame 310. The end of the piston rod of the first cylinder 340 is fixedly connected to the connecting seat 330, and the piston rod of the first cylinder 340 is coaxially arranged with the driven rotating shaft 230.

[0035] Understandably, cylinders offer advantages such as fast response, high control precision, and stable thrust, enabling the pressure plate 320 to quickly and accurately press the stainless steel kettle. Simultaneously, the coaxial arrangement helps reduce eccentric loads, decrease mechanical wear, extend equipment lifespan, and improve overall operational stability and work efficiency.

[0036] Furthermore, referring to Figures 1 and 2, according to some embodiments of the present invention, the cutting device includes a third frame 410, a third drive mechanism, and a cutting disc 420. The third frame 410 is fixedly connected to the machine base 100, and the third drive mechanism is installed on the third frame 410. The third drive mechanism is connected to the cutting disc 420 and can drive the cutting disc 420 closer to the driven shaft 230 to cut the stainless steel kettle, or drive the cutting disc 420 away from the driven shaft 230, thereby realizing the cutting operation on the edge of the stainless steel kettle.

[0037] Further referring to Figures 1 and 2, according to some embodiments of the present invention, the third drive mechanism includes a second cylinder 430, a crank handle 440, and a swing arm 450. The second cylinder 430 is fixedly mounted on the third frame 410. The piston rod of the second cylinder 430 is fixedly connected to one end of the crank handle 440. One end of the crank handle 440 is fixedly connected to one side of the swing arm 450. The other side of the swing arm 450 is rotatably connected to the third frame 410. The axial direction of the swing arm 450 is the same as the axial direction of the active rotating shaft 220. One end of the swing arm 450 is fixedly connected to the cutting disc 420.

[0038] It is understandable that the cutting disc 420 is driven to move by a linkage mechanism consisting of a second cylinder 430, a crank handle 440, and a swing arm 450. This linkage structure drives the crank handle 440 to swing the swing arm 450 through the cylinder, thereby driving the cutting disc 420 to cut into or out of the edge of the stainless steel kettle. It has the characteristics of simple structure, reliable operation, and high transmission efficiency. It can achieve a large stroke cutting action in a limited space, and it is easy to adjust the cutting angle and force to meet the edge cutting requirements of stainless steel kettles of different thicknesses and materials.

[0039] Furthermore, referring to Figures 1 and 2, according to some embodiments of the present invention, a groove 460 extending along the swing path of the swing arm 450 is provided on the third frame 410. One end of the swing arm 450 extends out of the groove 460 and is fixedly connected to the cutting disc 420. The width of the groove 460 is adapted to the diameter of the swing arm 450.

[0040] Understandably, the chute 460 guides and limits the movement trajectory of the swing arm 450, ensuring that the cutting disc 420 maintains a stable path during cutting and preventing uneven cutting or workpiece damage due to deviation. Simultaneously, the width of the chute 460 matches the diameter of the swing arm 450, ensuring smooth movement and enhancing the overall structural rigidity and vibration resistance, thus improving cutting accuracy and equipment operational stability.

[0041] Furthermore, referring to Figures 1 and 2, according to some embodiments of the present invention, the first driving mechanism includes a drive motor 260 and a gearbox 270. The drive motor 260 is fixedly installed on the bottom of the machine base 100, and the gearbox 270 is installed on the side of the machine base 100. The drive motor 260 is connected to the drive shaft 220 through the gearbox 270.

[0042] Understandably, the drive motor 260 and gearbox 270 provide stable and controllable power output, ensuring that the stainless steel pot rotates at a constant speed during the cutting process, thereby improving the uniformity of the cut and the surface quality. Furthermore, the drive motor 260 is mounted at the bottom of the machine base 100, and the gearbox 270 is located on the side, resulting in a rational overall layout that saves space, facilitates maintenance, lowers the center of gravity of the equipment, and enhances operational stability and safety.

[0043] Furthermore, referring to Figures 1 and 2, according to some embodiments of the present invention, an electrical control box 500 is installed on the side of the machine base 100, and the drive motor 260, the first cylinder 340 and the second cylinder 430 are all electrically connected to the electrical control box 500.

[0044] Understandably, by using the electrical control box 500 to uniformly control the drive motor 260, the first cylinder 340, and the second cylinder 430, the coordinated and programmed operation of the various actuators of the equipment is achieved, improving the overall automation level, reducing manual intervention, and facilitating continuous and efficient processing of the stainless steel kettle trimming process. The electrical control box 500 is located on the side of the machine base 100, saving space and facilitating daily inspection and maintenance; at the same time, the electrical control system has safety functions such as overload protection and emergency stop control, effectively ensuring the stability of equipment operation and the safety of operators.

[0045] Furthermore, in some embodiments of this utility model, the driven rotating shaft 230 can be an air shaft. The air shaft is connected to an air passage. It is understood that after compressed air is introduced, the outer surface of the air shaft expands, thus tightly fitting against the inner wall of the stainless steel kettle, achieving rapid and reliable clamping and positioning. Compared to traditional mechanical clamping methods, the air shaft provides uniform contact pressure, avoiding deformation or damage to the stainless steel kettle due to uneven clamping force, effectively improving the stability and reliability of workpiece clamping. The air shaft has a compact overall structure, is easy to install, and experiences uniform force during rotation, making it less prone to eccentric vibration. This helps improve the smoothness of the rotation process and cutting accuracy, thereby improving the edge quality of the stainless steel kettle. The air shaft provides flexible contact during clamping, reducing damage to the inner wall of the stainless steel kettle and minimizing mechanical wear, which helps extend the service life of the equipment and related components, reducing the failure rate.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
