[0031] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0032] Implementation 1, such as Figure 1 and Figure 2 As shown in the embodiment of this disclosure, a floating grinding device for removing burrs and sharp edges from cookware is proposed. The device includes: a grinding mechanism 100 for grinding burrs and sharp edges from the surface of the cookware to be treated; X, Y, and Z axis adjustment mechanisms 200 for moving the grinding mechanism 100 in the X, Y, and Z axis directions, respectively; and a floating compensation mechanism 300, one end of which is slidably connected to the X, Y, and Z axis adjustment mechanism 200, and the other end of which is rotatably connected to the grinding mechanism 100, for causing the grinding mechanism 100 to float so that the working surface of the grinding wheel 130 of the grinding mechanism 100 adaptively abuts against the surface of the cookware to be treated, thereby achieving continuous and stable grinding processing.

[0033] The device of this embodiment is mounted on a frame and housing 600, or other worktables. The frame and housing are equipped with a rotating mechanism 610, which uses vacuum to hold the cookware 800 in place. A grinding device is positioned on one side of the cookware to be ground. The cookware rotates at low speed under the action of the rotating mechanism. The grinding mechanism is adjusted via X, Y, and Z axis adjustment mechanisms to ensure that the corresponding working surface of the grinding wheel abuts against the surface of the cookware 800 to be processed, which is of the corresponding size. When the cookware rotates, a floating compensation mechanism compensates for unevenness at the end face, maintaining constant contact between the grinding wheel working surface and the surface to be processed. The high-speed rotation of the grinding wheel achieves uniform grinding of the surface to be processed, removing burrs and roughness. This device can be used on the edge of the cookware, and is also applicable to other surfaces that can be ground using the grinding device of this embodiment. Figure 2 As shown, the grinding wheel of the grinding mechanism can have multiple grinding surfaces. After one surface wears out, a new surface can be replaced by changing the end face or adjusting the direction of the grinding mechanism to continue grinding the surface of the cookware, improving the utilization rate of the grinding wheel and saving costs. The grinding mechanism can be rotated to different positions via the X, Y, and Z axis adjustment mechanism to adjust its position on the radial side of the cookware to accommodate cookware of different sizes. The grinding mechanism can rotate 360° along the end of the floating compensation mechanism to flexibly adjust the direction of the grinding wheel and utilize different working surfaces of the grinding wheel.

[0034] like Figure 3 As shown, when the grinding mechanism is adjusted to be vertical, the grinding wheel is in a horizontal state, and the circumferential edge of the bottom surface of the grinding wheel is used to grind the upper surface of the cookware edge to be treated; as shown Figure 4 As shown, when the grinding mechanism is adjusted to be horizontal, the grinding wheel is in a vertical position, and the circumferential side end face of the grinding wheel is used to grind the circumferential edge of the cookware to be treated. Figure 5 As shown, before polishing, there were burrs and rough edges on the edge of the pot. After polishing by the polishing mechanism, the burrs and rough edges were removed, forming a smooth chamfer, as shown. Figure 6 As shown, the X, Y, and Z axis adjustment mechanisms allow the grinding mechanism to be finely adjusted along the X, Y, and Z axes respectively, achieving their respective adjustment functions. The floating mechanism, through adaptive adjustment, compensates for unevenness of the end face caused by deformation, burrs, or tilting of the cookware itself, thereby ensuring stable grinding pressure. Specifically, this results in: improved chamfer uniformity: avoiding inconsistent grinding depth caused by undulations in the cookware edge; and extended grinding wheel life: reducing abnormal wear caused by localized hard contact. In other words, the design of the floating mechanism indirectly reduces abnormal stress or displacement of the grinding wheel caused by external forces, thereby protecting the grinding wheel and improving grinding uniformity.

[0035] The polishing apparatus, frame and housing, and rotating mechanism of this disclosure constitute a floating polishing system.

[0036] like Figure 2As shown, the X, Y, and Z axis adjustment mechanism 200 includes: grinding mechanisms that adjust the grinding mechanism from the x-axis, z-axis, and y-axis directions respectively, and are sequentially connected to the X-axis adjustment mechanism 200-1, the Z-axis adjustment mechanism 200-2, and the Y-axis adjustment mechanism 200-3. The three adjustment mechanisms—X-axis adjustment mechanism, Y-axis adjustment mechanism, and Z-axis adjustment mechanism—are closely connected, resulting in a compact structure.

[0037] like Figure 1 As shown, the three adjustment mechanisms, namely X-axis adjustment mechanism 200-1, Z-axis adjustment mechanism 200-2, and Y-axis adjustment mechanism 200-3, each include: a base plate 240 with a hollow groove in the central area, a sliding plate 250, a transmission slider (not shown in the figure), and a lead screw (not shown in the figure); the lead screw passes through the hollow groove and the transmission slider along the length direction of the base plate 240, and the transmission slider is threadedly connected to the lead screw; one end of the lead screw passes through the side wall of the hollow groove, and a manual wheel is provided at the end; the other end of the lead screw is rotatably connected to the other side wall of the hollow groove through a bearing or other structure.

[0038] like Figure 3 As shown, the base plate 240 has limiting grooves 241 extending along the length direction on both sides of its width direction, and the sliding plate 250 has limiting sliders 251 extending along the length direction on both sides of its width direction. The limiting sliders 251 slide in cooperation with the corresponding limiting grooves. The sidewalls of the limiting grooves 241 and the bottom wall form acute angles. The cooperation between the limiting grooves 241 and the limiting sliders 251 allows the sliding plate 250 and the base plate 240 to slide relative to each other while also providing a limiting function, making the connection between the sliding plate and the base plate more stable in the width direction. The transmission slider is disposed in the hollow groove, and the first surface of the transmission slider is connected to the sliding plate. There is a gap between the second surface of the transmission slider and the bottom surface of the hollow groove, that is, the second surface of the transmission slider does not contact the bottom surface of the hollow groove; the transmission slider has a cuboid structure, and the size of the transmission slider is slightly smaller than the size of the hollow groove, so that when the lead screw rotates, the transmission slider can move in the hollow groove to drive the sliding plate to move; the second surface of the transmission slider is suspended, and if the base plate has a bottom surface, friction can be reduced; the base plate of the Z-axis adjustment mechanism 200-2 is connected to the sliding plate 250 of the X-axis adjustment mechanism 200-1 through the connecting assembly 230; the sliding plate of the Z-axis adjustment mechanism 200-2 is connected to the base plate of the Y-axis adjustment mechanism 200-3 through the pneumatic lifting limit mechanism 260.

[0039] The X-axis adjustment mechanism 200-1 is a horizontal adjustment mechanism. The connecting component is vertically perpendicular to the X-axis adjustment mechanism, or the connecting component forms an obtuse angle with the X-axis adjustment mechanism in the direction of cookware movement. The Z-axis adjustment mechanism, through the angle adjustment of the connecting component, causes the plane of the Z-axis adjustment mechanism's movement direction to change angle with the horizontal adjustment direction of the X-axis adjustment mechanism. The Y-axis adjustment mechanism allows for fine-tuning of the grinding wheel along the Y-axis direction, quickly locating and aligning it with the cookware's quadrant points for grinding. The Z-axis adjustment mechanism allows for fine-tuning of the grinding wheel along the Z-axis direction, adjusting the grinding wheel's feed rate to the cookware.

[0040] The first surface of the cylinder in the pneumatic lifting and limiting mechanism can be connected to the sliding plate of the Z-axis adjustment mechanism. The second surface of the cylinder is provided with outwardly protruding guide rails, which are located on both sides of the second surface of the cylinder along its width and length. A movable plate is connected to the telescopic end of the pneumatic lifting and limiting mechanism. The movable plate includes a base plate and an extension plate, both L-shaped. The base plate is connected to the telescopic end of the pneumatic lifting and limiting mechanism. Two receiving grooves are provided in the central area of ​​the extension plate, accommodating corresponding guide rails on the cylinder. The side of the extension plate facing the cylinder is clearance-fitted with the second surface of the cylinder, allowing the extension plate to move along the guide rails for limitation when the telescopic end of the pneumatic lifting and limiting mechanism moves. The sliding plate of the Z-axis adjustment mechanism and the cylinder can be detachably connected. The base plate of the Y-axis adjustment mechanism and the extension plate can be detachably connected.

[0041] The Y-axis adjustment mechanism, under the action of the pneumatic lifting and limiting mechanism, increases the movement range in the Z-axis adjustment direction. The movement direction of the Y-axis adjustment mechanism is horizontal and perpendicular to the adjustment direction of the X-axis adjustment mechanism. The pneumatic lifting and limiting mechanism drives the grinding wheel to move up and down within a specified range. The cylinder drives the grinding wheel downward for grinding. After the grinding is completed, the cylinder drives the grinding wheel upward to facilitate the removal of the pot from the mold.

[0042] like Figure 1 As shown, the X-axis adjustment mechanism further includes: a T-slot connecting plate 210, one side of which is provided with a concave and inverted T-slot slide rail, and the other side is used to be mounted on the worktable 700; a transition connecting plate 220, one side of which is provided with a T-nut (not shown in the figure), the shape of which matches the T-slot, and the T-nut can be slidably engaged with the T-slot slide rail, and the other side is connected to the base plate 240 of the X-axis adjustment mechanism.

[0043] The first surface of the T-slot connecting plate has inverted T-slots extending through the length direction on both sides along the width direction. The second surface is used for mounting on the workbench, frame, or cabinet 600. The first surface can be the front, and the second surface can be the bottom. The transition connecting plate has multiple symmetrical positioning holes along the length direction on both sides along the width direction. One set of the first two sets of symmetrical positioning holes near the end is connected to a T-nut by screws. The remaining positioning holes are detachably connected to the base plate of the X-axis adjustment mechanism by screws. In other words, the T-nut has two selectable installation positions on the transition connecting plate 220. The T-nut is detachably connected to the transition connecting plate by screws. The T-nut is set in the T-slot and slides with the T-slot. The shape of the T-nut matches the T-slot, achieving both snap-fit ​​and sliding.

[0044] The X-axis adjustment mechanism and T-slot mounting plate of this embodiment can adjust the grinding mechanism horizontally. The T-slot mounting plate can adjust for cookware of different diameters. The X-axis adjustment mechanism allows for fine adjustment of the grinding wheel along the X-axis, dividing the grinding surface into N small segments to save on grinding wheel usage and reduce grinding wheel costs. The segmentation accuracy can be set according to actual conditions.

[0045] like Figure 1 As shown, the connecting assembly includes: a support frame 231, which includes two support plates (not shown in the figure) spaced apart, one end of the two support plates being fixedly connected to the sliding plate 250 of the X-axis adjustment mechanism, and the other end of the two support plates being symmetrically provided with arc-shaped grooves; and an angle adjustment block 232, which is disposed between the two support plates, one end of which is rotatably connected to the two support plates, the rotation axis being concentric with the arc of the positioning hole, and the other end face of the angle adjustment block 232 being connected to the base plate of the Z-axis adjustment mechanism 200-2. The angle adjustment block 232 is symmetrically provided with multiple threaded holes arranged along an arc on both sides near the other end, and the corresponding threaded holes and any position of the arc-shaped groove are fastened to the angle adjustment block and the support frame by bolts.

[0046] It should be noted that one end of the support frame can be tilted at a certain angle in the vertical direction to connect with the sliding plate of the X-axis adjustment mechanism; the other end can be provided with an end that bends towards the cookware. The end is provided with an arc-shaped groove. The angle adjustment block can be an isosceles triangular block structure. The apex of the angle adjustment block is hinged to the two support plates through a pivot. The pivot is concentric with the arc of the positioning hole. The two opposite triangular sides of the angle adjustment block are provided with multiple threaded holes arranged along the arc, which can be three. Bolts are fastened through the arc-shaped groove and the corresponding threaded holes, which can fix the angle adjustment block at any position in the arc-shaped groove. The arc-shaped threaded holes match the arc-shaped groove. The bolts fix the corresponding threaded holes at different positions in the arc-shaped groove to adjust the rotation angle of the angle adjustment block, thereby adjusting the pitch rotation of the Z-axis adjustment mechanism. The connecting component is the angle adjustment and locking mechanism. The angle adjustment and locking mechanism works together with the X-axis adjustment mechanism to realize the free switching and adjustment of different sizes and various types of cookware.

[0047] like Figure 1 and Figure 2 As shown, the floating compensation mechanism includes: a central connecting plate 310, the first surface of which is connected to the X, Y, and Z axis adjustment mechanism 200, and a linear limiting guide rail 311 arranged along the length direction in the central area of ​​the second surface of the central connecting plate 310; a linear slider 320, which is slidably connected to the linear limiting guide rail 311; two linear sliders can be separately provided to increase the rigidity of the structure in other directions and prevent lateral vibration; and a floating component 330, one end of which is fixed to the central connecting plate 310, and the other end can reciprocate along the length direction of the linear limiting guide rail 311 under the action of the linear slider.

[0048] Specifically, the first surface of the connecting plate is connected to the sliding plate of the Y-axis adjustment mechanism 200-3. The linear limiting guide rail 311 has an outwardly protruding protrusion structure, and the central area on both sides of the protrusion along the width direction is provided with a limiting groove that extends inward along the length direction. The central area of ​​the linear slider is provided with a sliding groove, and the two side walls opposite to the sliding groove are provided with relatively outwardly protruding protrusions. The protrusions cooperate with the limiting grooves, and the side of the linear slider facing the connecting plate is in clearance fit with the connecting plate. One end of the floating component is fixedly connected to the connecting plate, and the middle part of the structure is connected to the linear slider, so that the other end of the floating component reciprocates along the length direction of the linear limiting guide rail under the guidance of the linear limiting guide rail.

[0049] like Figure 1As shown, the floating component 330 includes: a U-shaped connecting plate 331 spanning the linear slider 320 and connected to the central connecting plate 310 at both ends; two elastic elements 332, each disposed on one side of the linear slider 320, with one end of each elastic element connected to the U-shaped connecting plate 331; a floating connecting plate 333 disposed at the other end of each elastic element 332; a sliding connecting plate 334 passing through the floating connecting plate 333 and the U-shaped connecting plate 331 and connected to the floating connecting plate 333, with one side of the sliding connecting plate connected to the linear slider 320; and two connecting rods 335, each disposed at a distance from one end of the sliding connecting plate 334 at both ends, with a grinding mechanism 100 rotatably disposed between the other ends of the two connecting rods 335.

[0050] It should be noted that the U-shaped groove of the U-shaped connecting plate accommodates the linear slider, and the side wall end face of the U-shaped groove is connected to the central connecting plate. The two ends of the elastic element 332 are respectively connected to the bottom surface of the U-shaped connecting plate 331 and the first surface of the floating connecting plate 333. The floating connecting plate 333 and the central connecting plate 310 have a gap and do not contact each other. The elastic element can be a hollow cylindrical elastic rubber, with a central column passing through it. One end of the central column passes through and connects to the central connecting plate. One end of the elastic element is connected to the bottom surface of the central connecting plate, and the other end of the central column passes through the floating connecting plate 333. A limit plate is provided at the other end of the central column, and the floating connecting plate 333 is positioned above the limit plate. The other end of the elastic element is connected to the floating connecting plate 333. When the floating connecting plate moves, it floats under the buffering effect of the elastic element, and large floating movements are avoided under the action of the limit plate, maintaining the stability of the device. The floating connecting plate can also be a U-shaped structure.

[0051] The sliding connecting plate 334 has a T-shaped structure. The vertical plate of the T-shaped structure passes through the U-shaped groove of the floating connecting plate 333 and the U-shaped connecting plate 331. The vertical plate of the sliding connecting plate is connected to the floating connecting plate, and the movement of the floating connecting plate drives the movement of the sliding connecting plate. The width of the vertical plate is the same as that of the linear slider. The U-shaped groove has a slightly larger capacity than the vertical plate and the linear slider, allowing the linear slider 320 to slide along the linear limiting guide rail. The horizontal plates of the sliding connecting plate 334 are connected to one end of a connecting rod, with the two connecting rods spaced apart. The grinding mechanism is located between the other ends of the two connecting rods. The grinding wheel floating compensation mechanism consists of a central connecting plate, linear guide rail and linear slider, fixed connecting plate, floating connecting plate, sliding connecting plate, and cylindrical elastic rubber, etc. Its function is to ensure that when the workpiece undergoes deformation and circular runout, the grinding wheel can float up and down, always ensuring that the working surface of the grinding wheel can contact the workpiece surface for grinding.

[0052] like Figure 1 As shown, the grinding mechanism 100 includes: a grinding wheel rotation and locking mechanism 110, one end of which is provided with a clamping flange 111, the clamping flange 111 is rotatable and laterally movable and is provided with a connecting column 112, both ends of the connecting column 112 are respectively connected to the other end of the corresponding connecting rod 335; a motor 120, which is provided on one side of the grinding wheel rotation and locking mechanism 110; and a grinding wheel 130, which is provided on the other side of the grinding wheel rotation and locking mechanism 110 and connected to the output shaft of the motor 120.

[0053] The grinding mechanism of this embodiment further includes a flange with lugs for connecting the motor and the grinding wheel rotation and locking mechanism, facilitating their installation. One end of the grinding wheel rotation and locking mechanism has a through transverse circular opening near its end. A cutout extends from the circular opening to the end, dividing the end into an upper flange and a lower flange. The circular opening and the two flanges form a clamping flange. A connecting column passes through the circular opening. The upper and lower flanges are adjusted with bolts to lock the grinding wheel rotation and locking mechanism. When loosened, the grinding wheel rotation and locking mechanism can rotate around the connecting column and move laterally along it. The other end of the two connecting rods can also have a clamping flange, and the connecting column is secured with bolts. The motor can be mounted on one side of the grinding wheel rotation and locking mechanism via the flange with lugs. The motor's output shaft passes through the central circular hole of the grinding wheel rotation and locking mechanism and the central hole of the flange with lugs. The grinding wheel shaft passes through the circular hole of the grinding wheel rotation and locking mechanism, and the motor's output shaft is located in the central hole of the grinding wheel shaft. The grinding wheel rotation and locking mechanism allows for horizontal and vertical installation of the grinding wheel and enables multi-directional grinding.

[0054] like Figure 3 and 4 As shown, the grinding wheel includes: a first working surface 131, which is the circumferential surface of the grinding wheel 130 facing the motor, i.e., the top surface; a second working surface 132, which is the circumferential surface of the grinding wheel 130 away from the motor, i.e., the bottom surface; and a second working surface 133, which is the circumferential side end face of the grinding wheel 130.

[0055] The grinding wheel is made of CBN material, and both end faces and the circumferential side can be used as grinding surfaces. The first working surface: When the grinding device is working, adjust the grinding mechanism so that the first working surface faces the surface to be treated on the workpiece below. The first working surface abuts against the edge of the cookware, and the cookware rotates at a low speed while the grinding wheel rotates at a high speed, achieving grinding of the cookware's edge surface; the second working surface: When the grinding device is working, if... Figure 3 As shown, the grinding mechanism is adjusted so that the second working surface faces the surface of the workpiece to be ground, and the second working surface abuts against the surface of the cookware edge to be treated. The cookware rotates, thus grinding the surface of the cookware edge. Figure 4As shown, the grinding mechanism is adjusted so that the third working surface faces the workpiece surface to be ground, and the second working surface abuts against the edge of the cookware. The cookware rotates, thus grinding the edge surface. The grinding wheel has three working surfaces for grinding the cookware: the top and bottom surfaces and the outer cylindrical side. After one working surface wears out, a new processing surface can be obtained by changing the end face or adjusting the direction of the grinding mechanism, improving the utilization rate of the grinding wheel and extending its service life. The specific working surfaces of the grinding mechanism can be adjusted according to actual conditions to achieve the grinding treatment of the cookware edge.

[0056] The floating grinding device of this disclosure has many advantages, such as a wide range of applicable cookware types and specifications, good grinding quality and efficiency, convenient adjustment, and good stability.

[0057] Example 2, as follows Figure 7 and 8 As shown, the polishing device in Embodiment 1 further includes: at least one pot edge pressing mechanism 400, which is at least disposed on one side of the polishing mechanism 100. One end of the pot edge pressing mechanism 400 is rotatably disposed on the floating compensation mechanism 300, and the other end is retractable. When the other end is extended, the other end is used to contact the upper surface of the edge of the pot 800 to press the pot edge.

[0058] In this embodiment, a pressure-plate mechanism can be provided on each side of the grinding mechanism. The pressure-plate mechanism is rotatably mounted on the floating compensation mechanism to adjust the pitch direction of the pressure-plate mechanism to regulate the contact force. The other end is telescopic to adjust the x-axis direction of the other end, thereby adjusting the contact range between the pressure-plate mechanism and the edge of the pot. When the pot rotates, the pressure-plate mechanism maintains the stability of the pot rotation process by pressing down on the edge of the pot.

[0059] like Figure 7 As shown, specifically, the pot edge pressing mechanism includes: a rotating block 410, rotatably disposed at one end of the floating compensation mechanism 300 near the grinding mechanism 100; a telescopic rod 420, one end of which is telescopically disposed on the rotating block 410; an adjusting block 430, rotatably disposed at the other end of the telescopic rod 420, and movable on the telescopic rod 420; and a pot edge pressing plate 440, rotatably disposed on the adjusting block 430, which, when the telescopic rod 420 is extended, contacts the upper surface of the edge of the pot 800 to press the pot edge.

[0060] Two pressure-plate mechanisms can be provided in this embodiment, respectively located on both sides of the grinding mechanism. The rotating block in this embodiment can have clamping flanges in different directions at both ends. An extension rod is also provided at the other end of each of the two connecting rods, with a clamping flange at the end of the extension rod. The clamping flange of the extension rod is connected to the clamping flange at one end of the rotating block via a connecting column. Each clamping flange can be fastened with bolts. By adjusting the corresponding bolts, the rotating block can rotate, and the pressure-plate can be adjusted in the pitch direction to adjust the contact force. The clamping flange at the other end of the rotating block passes through one end of the telescopic rod. The telescopic rod's extension and retraction can be adjusted via bolts, allowing the pressure-plate to be adjusted in the x-axis direction, thus adjusting the contact range between the pressure-plate mechanism and the edge of the pot. The rotating adjustment block 430 also has two clamping flanges, one of which passes through the other end of the telescopic rod. The rotating adjustment block 430 can be adjusted via corresponding bolts, allowing the adjustment block to rotate around the telescopic rod and move horizontally along it. The rotating adjustment block can adjust the horizontal position of the pressure-plate. The connecting shaft of the pressure plate can be fastened to another clamping flange of the adjusting block with corresponding bolts, and the pressure plate can rotate around the connecting shaft. When the telescopic rod extends to the preset position, the pressure plate can be adjusted by tilting the rotating block to ensure that the pressure plate can press firmly against the edge surface of the cookware. Specifically, the position of the pressure plate can be adjusted according to the actual situation, and a corresponding clamping force can be applied. Figure 8 As shown, the pressure plate can rotate with the edge of the pot. The pressure plate is mainly used to apply pressure to the edge of the pot to balance centrifugal force or vibration, prevent the pot from shifting or jumping, keep the pot stable, and also has a certain grinding and flattening effect on small protruding burrs.

[0061] The device in this embodiment of the disclosure is equipped with a pot-side pressing mechanism, which presses down the pot side by adding flange bearings on both sides of the floating mechanism. The floating adjustment mechanism and the pot-side pressing mechanism do not affect each other and can adjust their respective positions according to the actual situation to achieve their own operation; the two are independent of each other.

[0062] Example 3, as follows Figure 9 As shown, based on Embodiment 1 or Embodiment 2, the device further includes: a flattening component 500, which is disposed upstream of the polishing mechanism 100 to pre-flatten the burrs and roughness on the surface of the cookware 800 to be treated.

[0063] The position of the flattening component can be adjusted according to the actual situation. The flattening component can be set directly on one side of the connecting rod, or it can be set upstream of the pressure pot side mechanism.

[0064] Specifically, the flattening assembly 500 includes: a mounting platform 530 connected to the floating compensation mechanism 300; a support rod 510, one end of which is connected to the mounting platform 530 via a torsion spring, and the other end of which is positioned above the cookware 800; and a pressure roller 520 rotatably mounted on the other end of the support rod 510 for contacting the surface of the cookware 800 to be treated, so that when the cookware rotates, it can flatten the burrs and roughness on the surface of the cookware 800 to be treated.

[0065] It should be noted that the mounting platform can have a built-in groove to accommodate a torsion spring. One end of the torsion spring is connected to the support rod, and the torsion spring applies pressure to the support rod, causing the pressure roller to abut against the upper surface of the cookware to be treated. The mounting platform can also be directly connected to the connecting rod via a rotating block, adjusting block, and telescopic rod to adjust the position of the pressure roller. When the cookware rotates, under the action of friction or burrs and sharp edges, the pressure roller can rotate with the cookware. Under the action of the pressure roller, the burrs and sharp edges are pre-rolled, reducing their height and smoothing out the sharp points. Figure 10 As shown, burrs and roughness increase friction, and the pressure roller rotates with the edge of the pot, without affecting its pressure on the burrs and roughness. Unlike grinding, this flattening method causes virtually no wear on the pressure roller. The mounting platform can also be connected to one side of the pot-side pressing mechanism via a rotating block, adjusting block, and telescopic rod. The positions of the flattening component and the pot-side pressing mechanism can be set according to actual conditions. Specifically, the rotating block can be connected to one side of the rotating block of the pot-side pressing mechanism, sharing a common pivot pin, without affecting the positional adjustment of the flattening mechanism and the pot-side pressing mechanism. The flattening mechanism pre-flattens the burrs and roughness, making them smooth and reducing height differences. This reduces repeated grinding by the grinding mechanism, and the smooth burrs and roughness reduce wear on the grinding wheel, thereby improving the efficiency and quality of subsequent grinding, shortening grinding time, and reducing grinding wheel wear.

[0066] The above description is only a preferred embodiment of the present disclosure. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present disclosure, and these improvements and modifications should also be considered within the protection scope of the present disclosure.
