Description

Technical Field

[0001] This invention relates to the field of metal polishing technology, specifically to a device for polishing the rough edges of round metal sheets used in air fryer production. Background Technology

[0002] As people's living standards improve, the market demand for air fryers is increasing. Air fryers utilize high-speed air circulation technology, combining rapidly circulating hot air with a unique internal spiral pattern to achieve the cooking effect and taste of fried food. Specifically, during heating, high-temperature hot air is generated inside the fryer, creating a crispy surface on the food while locking in internal moisture, resulting in a fragrant and crispy texture similar to regular fried food.

[0003] Patent application CN201921129612.5 discloses a device for polishing the rough edges of circular metal sheets used in air fryer production. A rotating shaft is fixed to the other end of a guide rod. A water tank is located on the top of a support platform, and rollers are evenly rotated within the tank. A polishing belt in a closed loop is wound around the outside of the rollers. Air jets and water jets are fixed sequentially on the left and right sides of the water tank. The device uses a cylinder to lower a partition frame, keeping the three rotating rollers locked to the circular metal sheet. A tension spring pulls the rollers to prevent them from loosening. A motor is started to rotate the polishing belt, causing the circular metal sheet to rotate accordingly. The high-speed rotating polishing belt and the low-speed rotating circular metal sheet create a polishing effect, polishing the burrs on the edges of the circular metal sheet. During polishing, water from the water jets washes the bottom surface of the polishing belt, and high-pressure gas from the air jets dries the surface of the polishing belt, improving the polishing effect.

[0004] When using existing equipment, it is difficult to make flexible adjustments according to the actual situation of the board material, which can easily create blind spots in the grinding or cause uneven grinding of the edges. At the same time, the clamping structure is not stable enough for the board material. When rotating at high speed, the board material is prone to jumping and moving, resulting in grinding marks of varying depths and affecting the surface finish. This in turn reduces processing efficiency and the yield rate of finished products. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for polishing the rough edges of circular metal sheets used in air fryer production, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for polishing the rough edges of circular metal sheets used in the production of air fryers, comprising a worktable, a baffle fixedly connected to the top of the worktable, a first track fixedly connected to the inner wall of the baffle, a positioning column fixedly connected to the top of the worktable, a driving mechanism movably connected to the outer wall of the first track, and a placement mechanism fixedly connected to the top of the worktable. The placement mechanism includes: A base is provided, with its bottom fixedly connected to a worktable and its top fixedly connected to a rotating seat. A turntable is rotatably connected to the top of the rotating seat via a bearing. A base plate is fixedly connected to the rear side of the base, with its bottom fixedly connected to the worktable and its top fixedly connected to a first connecting column. A first frame is fixedly connected to the top of the base plate, with a grinding assembly fixedly connected to the inner wall of the first frame and a second track fixedly connected to the outer wall of the first frame. An auxiliary assembly is movably connected to the outer wall of the first frame. The top of the turntable is used to place a circular metal sheet to be processed.

[0007] According to the above technical solution, the driving mechanism includes a first connecting plate, with a first right-angle plate fixedly connected to both the left and right sides of the first connecting plate, a first slider fixedly connected to the outer side of the first right-angle plate, the inner wall of the first slider being movably connected to a first track, and a first push rod fixedly connected to the bottom of the first right-angle plate, the bottom of the first push rod being fixedly connected to the worktable, wherein the first push rod is used to control the height of the first connecting plate.

[0008] According to the above technical solution, a pressure plate is rotatably connected to the bottom of the first connecting plate via a bearing, and a first motor is fixedly connected to the top of the first connecting plate. The output end of the first motor is fixedly connected to the pressure plate. The first motor is used to drive the circular metal sheet being processed to rotate through the pressure plate.

[0009] According to the above technical solution, the grinding assembly includes a connecting frame, the inner wall of which is fixedly connected to a first connecting column, and second connecting plates fixedly connected to both the upper and lower sides of the connecting frame. The outer wall of the second connecting plate is fixedly connected to a first frame. An arc-shaped groove is provided on the outer wall of the connecting frame, and an adjustment assembly is movably connected to the inner wall of the arc-shaped groove. A second frame is fixedly connected to the outer wall of the connecting frame, and a threaded column is rotatably connected to the inner wall of the second frame via a bearing. A second motor is fixedly connected to the top of the second frame, and the output end of the second motor is fixedly connected to the threaded column. The second motor controls the position of the adjustment assembly by rotating the threaded column. By setting the grinding assembly, the grinding angle can be flexibly adjusted, avoiding grinding blind spots or uneven edges caused by a fixed angle. This allows the grinding roller to conform to the edge of the circular board, ensuring that the burrs are completely removed without missed grinding or over-grinding, thus improving the grinding consistency of the board.

[0010] According to the above technical solution, a second connecting column is fixedly connected to the front side of the connecting frame. There are two second connecting columns, and each of the two second connecting columns has a through groove on its outer wall. A first elastic component is fixedly connected to the inner wall of the through groove. A force-bearing plate is fixedly connected to the movable end of the first elastic component. A connecting block is provided on the outer wall of the force-bearing plate. There are two connecting blocks. The inner wall of the connecting block closest to the connecting frame is movably connected to the second connecting column, and the outer wall of the connecting block closest to the connecting frame is fixedly connected to an auxiliary component. The inner wall of the connecting block furthest from the connecting frame is fixedly connected to the second connecting column. The outer wall of each connecting block is fixedly connected to a second elastic component. A third connecting plate is fixedly connected to the end of the second elastic component away from the connecting block. A pressure ball is fixedly connected to the side of the third connecting plate away from the second elastic component. The surface of the pressure ball is in contact with the circular metal plate. When the circular metal plate rotates, it will roll along with it. By setting the grinding component, the pressure ball stabilizes the area near the grinding point and provides multiple flexible supports in the area near the grinding point. This can effectively suppress the jumping and swaying of the plate during rotation, reduce uneven grinding marks caused by vibration, and thus improve the stability and pass rate of grinding.

[0011] According to the above technical solution, the auxiliary component includes a fourth connecting plate. The bottom of the fourth connecting plate is fixedly connected to the connecting block. Both sides of the connecting block are rotatably connected to connecting rods via bearings. The end of the connecting rod away from the fourth connecting plate is rotatably connected to a force-bearing block via a bearing. A second slider is fixedly connected to the outer wall of the force-bearing block. The inner wall of the second slider is movably connected to the first frame. The change in the position of the force-bearing block is used to adjust the position of the connecting block. By setting the auxiliary component, the position of the connecting block can be adjusted when adjusting the angle, ensuring that the grinding roller can smoothly reach the predetermined deflection position, avoiding incomplete adjustment or jamming caused by interference, thereby further enhancing the smoothness of angle adjustment and the overall reliability of the device.

[0012] According to the above technical solution, the adjustment component includes a third frame, with third sliders fixedly connected to both the left and right sides of the outer wall of the third frame. The outer wall of the third slider is movably connected to an arc-shaped groove, and a sliding plate is movably connected to the outer wall of the third slider. A fourth slider is fixedly connected to the outer wall of the sliding plate. A push rod is fixedly connected to the side of the third slider away from the third frame, and the inner wall of the fourth slider is threadedly connected to a threaded column. The rotation of the threaded column is used to adjust the height of the sliding plate. By setting the adjustment component, when the grinding roller contacts the circular metal plate, the third elastic component can absorb the impact force caused by the unevenness of the plate surface, keeping the grinding roller with a flexible clamping force; it can make the grinding force evenly distributed, avoiding local overheating or excessive grinding, thereby improving the grinding quality.

[0013] According to the above technical solution, a third elastic component is fixedly connected to the inner wall of the third frame, a second right-angle plate is fixedly connected to the movable end of the third elastic component, a slot is opened at the top of the second right-angle plate, a sixth slider is fixedly connected to the top of the third frame, the outer wall of the sixth slider is movably connected to the slot, a fifth connecting plate is fixedly connected to the side of the second right-angle plate away from the third elastic component, wherein there are two fifth connecting plates, and a grinding roller is rotatably connected between the two fifth connecting plates through a bearing, a third motor is fixedly connected to the bottom of the lower fifth connecting plate, and the output end of the third motor is fixedly connected to the grinding roller, wherein the third motor is used to drive the grinding roller to rotate.

[0014] Compared with the prior art, the present invention provides a device for polishing the rough edges of circular metal sheets used in air fryer production, which has the following advantages: 1. By setting an adjustment component, when the grinding roller comes into contact with the circular metal plate, the third elastic component can absorb the impact force caused by the unevenness of the plate surface, so that the grinding roller maintains a flexible clamping force; it can make the grinding force evenly distributed, avoid local overheating or excessive grinding, thereby improving the grinding quality.

[0015] 2. By setting up a grinding component, the present invention can flexibly adjust the grinding angle, avoiding grinding blind spots or uneven edges caused by a fixed angle, so that the grinding roller can fit the edge of the round board, ensuring that the burrs are completely removed and there is no missed grinding or over-grinding, thus improving the grinding consistency of the board.

[0016] 3. By setting up a grinding component, the present invention stabilizes the area near the grinding point with pressure balls and provides multiple flexible supports in the vicinity of the grinding point. This can effectively suppress the jumping and swaying of the board during rotation, reduce uneven grinding marks caused by vibration, and thus improve the stability and pass rate of grinding.

[0017] 4. By setting up auxiliary components, the present invention can adjust the position of the connecting block when adjusting the angle, ensuring that the grinding roller can smoothly reach the predetermined deflection position, avoiding the phenomenon of incomplete adjustment or jamming caused by interference, thereby further enhancing the smoothness of angle adjustment and the overall reliability of the device.

A first push rod 204 is fixedly connected to the bottom of the first right-angle plate 202. The bottom of the first push rod 204 is fixedly connected to the worktable 1. The first push rod 204 is used to control the height of the first connecting plate 201. A pressure plate 205 is rotatably connected to the bottom of the first connecting plate 201 through a bearing. A first motor 206 is fixedly connected to the top of the first connecting plate 201. The output end of the first motor 206 is fixedly connected to the pressure plate 205. The first motor 206 is used to drive the circular metal plate to be processed to rotate through the pressure plate 205. When the circular metal plate needs to be processed, the circular metal plate is first placed on the turntable 303 and the outer wall of the circular metal plate is made to fit against the positioning post 103. Then, the first push rod 204 is activated, which drives the drive mechanism 2 to descend as a whole until the lower surface of the pressure plate 205 is in close contact with the circular metal plate. Next, the first motor 206 is activated to drive the pressure plate 205 to rotate, and the rotating pressure plate 205 drives the circular metal plate to rotate together. At this time, the grinding component 31 in the placement mechanism 3 performs burr grinding on the rotating circular metal plate.

[0024] The placement mechanism 3 includes: a base 301, the bottom of which is fixedly connected to the worktable 1; a rotating seat 302 is fixedly connected to the top of the base 301; a turntable 303 is rotatably connected to the top of the rotating seat 302 via a bearing; a base plate 304 is fixedly connected to the rear side of the base 301; the bottom of the base plate 304 is fixedly connected to the worktable 1; a first connecting column 305 is fixedly connected to the top of the base plate 304; a first frame 306 is fixedly connected to the top of the base plate 304; a grinding component 31 is fixedly connected to the inner wall of the first frame 306; a second track 307 is fixedly connected to the outer wall of the first frame 306; and an auxiliary component 32 is movably connected to the outer wall of the first frame 306. The top of the turntable 303 is used to place the circular metal sheet to be processed.

[0025] Example 2: Please refer to Figure 7 Figure 10 Based on Embodiment 1, the present invention provides a technical solution: the grinding component 31 includes a connecting frame 311, the inner wall of the connecting frame 311 is fixedly connected to a first connecting post 305, and second connecting plates 312 are fixedly connected to both the upper and lower sides of the connecting frame 311. The outer wall of the second connecting plate 312 is fixedly connected to a first frame 306. An arc-shaped groove 313 is formed on the outer wall of the connecting frame 311, and an adjustment component 33 is movably connected to the inner wall of the arc-shaped groove 313. A second frame 318 is fixedly connected to the outer wall of the connecting frame 311, and a threaded post 319 is rotatably connected to the inner wall of the second frame 318 via a bearing. A second motor 3110 is fixedly connected to the top of the second frame 318, and the output end of the second motor 3110 is fixedly connected to the threaded post 319. The second motor 3110 controls the position of the adjustment component 33 by rotating the threaded post 319. Two second connecting posts 314 are fixedly connected to the front side of the connecting frame 311. Each of the outer walls of 314 has a through groove 315. The inner wall of the through groove 315 is fixedly connected to a first elastic component 316. The movable end of the first elastic component 316 is fixedly connected to a force-bearing plate 317. The outer wall of the force-bearing plate 317 is provided with two connecting blocks 3111. The inner wall of the connecting block 3111 near the connecting frame 311 is movably connected to the second connecting column 314. The outer wall of the connecting block 3111 near the connecting frame 311 is fixedly connected to the auxiliary component 32. The outer wall of the connecting block 3111 away from the connecting frame 314 is fixedly connected to the auxiliary component 32. The inner wall of the connecting block 3111 is fixedly connected to the second connecting post 314. The outer walls of both connecting blocks 3111 are fixedly connected to the second elastic component 3112. The end of the second elastic component 3112 away from the connecting block 3111 is fixedly connected to the third connecting plate 3113. The side of the third connecting plate 3113 away from the second elastic component 3112 is fixedly connected to the pressure ball 3114. The surface of the pressure ball 3114 is in contact with the circular metal plate and will roll when the circular metal plate is rotated.

[0026] The auxiliary component 32 includes a fourth connecting plate 321. The bottom of the fourth connecting plate 321 is fixedly connected to the connecting block 3111. Both sides of the connecting block 3111 are rotatably connected to connecting rods 322 via bearings. The end of the connecting rod 322 away from the fourth connecting plate 321 is rotatably connected to a force-bearing block 323 via a bearing. The outer wall of the force-bearing block 323 is fixedly connected to a second slider 324. The inner wall of the second slider 324 is movably connected to the first frame 306. The change in the position of the force-bearing block 323 is used to adjust the position of the connecting block 3111. When the force-bearing block 323 is pushed by the push rod 333, the force-bearing block 323 slides along the first frame 306 via the second slider 324. The movement of the force-bearing block 323 pushes the fourth connecting plate 321 to move via the connecting rod 322, thereby causing the connecting block 3111 to move axially along the second connecting column 314, thus changing its position.

[0027] The adjustment component 33 includes a third frame 331. Third sliders 332 are fixedly connected to both the left and right sides of the outer wall of the third frame 331. The outer wall of the third sliders 332 is movably connected to an arc-shaped groove 313. A sliding plate 334 is movably connected to the outer wall of the third sliders 332. A fourth slider 335 is fixedly connected to the outer wall of the sliding plate 334. A push rod 333 is fixedly connected to the side of the third slider 332 away from the third frame 331. The inner wall of the fourth slider 335 is threadedly connected to a threaded post 319. The rotation of the threaded post 319 is used to adjust the height of the sliding plate 334. A third elastic component 336 is fixedly connected to the inner wall of the third frame 331. A second right-angle plate 337 is fixedly connected to the movable end of the third elastic component 336. A slot 3311 is opened at the top of the second right-angle plate 337. A third elastic component 335 is fixedly connected to the top of the third frame 331. The sixth slider 3312 is movably connected to the slot 3311 via its outer wall. A fifth connecting plate 338 is fixedly connected to the side of the second right-angle plate 337 away from the third elastic component 336. There are two fifth connecting plates 338, and a grinding roller 339 is rotatably connected between them via a bearing. A third motor 3310 is fixedly connected to the bottom of the lower fifth connecting plate 338. The output end of the third motor 3310 is fixedly connected to the grinding roller 339, which drives the grinding roller 339 to rotate. When the deflection angle of the adjusting component 33 needs adjustment, the second motor 3110 is activated, driving the threaded column 319 to rotate. The rotation of the threaded column 319 causes the fourth slider 335 to move up and down along its axial direction. The movement of the fourth slider 335, in turn, causes the sliding plate 334 to rise and fall. When the sliding plate 334 rises and falls, the third slider 332 slides along the arcuate groove 313 on the connecting frame 311 via the push rod 333. Therefore, the grinding roller 339 on the third frame 331 moves along the arc trajectory with the third slider 332, thereby changing the tilt angle of the grinding roller 339.
