[0002] Stainless steel tableware is a widely used type of tableware. Due to its unique material properties, it is widely used in many fields such as home, commercial catering, outdoor camping and public places. Stainless steel is not conducive to the growth and reproduction of bacteria, which is conducive to keeping tableware clean and hygienic. Stainless steel tableware contains trace metal elements such as manganese, titanium, cobalt and molybdenum, which are all indispensable trace elements for the human body. Using stainless steel tableware can indirectly supplement these elements.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 10The present invention provides a technical solution: a stainless steel workpiece polishing device, comprising: an equipment box 1 with a polishing liquid box 2 fixedly connected to one side; a rotating disk 9 is rotatably placed on the top of the equipment box 1, a bracket is rotatably installed at the center position of the bottom of the rotating disk 9, the bracket is fixedly connected to the equipment box 1, a plurality of hollow shafts 10 with a negative pressure environment inside are rotatably arranged in the middle of the rotating disk 9, a vacuum suction cup 17 for fixing a stainless steel bowl is installed on the top of the hollow shaft 10, a sealing piston 16 for cutting off the negative pressure of the hollow shaft 10 is arranged inside the hollow shaft 10, and an electromagnetic driving part for driving the sealing piston 16 is arranged below the sealing piston 16; a polishing part is placed on the top of the equipment box 1, and the polishing part includes a vertical polishing cloth wheel 35 and a horizontal polishing cloth wheel 37, and the horizontal polishing cloth wheel 37 A reciprocating power unit is set at one end for driving the horizontal polishing cloth wheel 37 to reciprocate along the axial direction; the feeding mechanism is placed on one side of the equipment box 1, and the feeding mechanism includes a lifting plate 21 that can be raised and lowered, and a vacuum suction cup 26 for taking and releasing materials is rotatably set on the top of the lifting plate 21, and a lifting piston 32 is fixedly connected to the bottom of the lifting plate 21, and a piston cylinder 29 is slidably set on the outer side of the lifting piston 32 for limiting and guiding the lifting plate 21, as well as pressurizing and removing dust. When the vacuum suction cup 26 picks up the stainless steel bowl downward, the electromagnetic drive unit is energized, and the hollow shaft 10 corresponding to the vacuum suction cup 26 closes the negative pressure state, and the piston cylinder 29 pressurizes the polishing liquid box 2. When the vacuum suction cup 26 lifts the stainless steel bowl upward, the negative pressure performs dust removal around the vertical polishing cloth wheel 35.

[0032] It should be noted that the present invention is provided with a controller, and the servo motor 3 19 drives the rotating disk 9 to rotate, so that the hollow shaft 10 is located at the loading position, and the two vacuum suction cups 26 move downward at the same time, and one of the vacuum suction cups 26 moves downward to adsorb the polished workpiece. At this time, the negative pressure of the vacuum suction cup 17 above the corresponding hollow shaft 10 disappears, and the other vacuum suction cup 26 adsorbs the stainless steel bowl to be processed. After the rotating shaft 23 lifts the vacuum suction cup 26, it rotates to remove the processed stainless steel bowl. The stainless steel bowl to be processed is placed on the top of the vacuum suction cup 17. When the rotating shaft 23 moves downward, the piston cylinder 2 9 pressurizes the interior of the polishing liquid tank 2. Under the action of air pressure, the polishing liquid inside the polishing liquid tank 2 is sprayed toward the stainless steel bowl located below through the spray pipe 33, and then the rotating disk 9 rotates counterclockwise so that the workpiece enters the outer side of the vertical polishing cloth wheel 35 and the horizontal polishing cloth wheel 37 after spraying, and is polished by the vertical polishing cloth wheel 35 and the horizontal polishing cloth wheel 37. During polishing, the hollow shaft 10 drives the stainless steel bowl to rotate, the horizontal polishing cloth wheel 37 contacts the bottom of the bowl, the vertical polishing cloth wheel 35 contacts the outer wall of the bowl, and the horizontal polishing cloth wheel 37 reciprocates along the axial direction, thereby performing reciprocating polishing.

[0033] like Figure 1 , 6As shown, it also includes a discharging mechanism, which includes a support seat 4 detachably mounted on one side of the equipment box 1, the top of the support seat 4 is fixedly connected to a limit rod 5, the outer side of the limit rod 5 is slidably connected to a lifting plate, the bottom of the lifting plate and the outer side of the limit rod 5 are sleeved with a spring 6 for setting the height of the top stainless steel bowl to a preset position, the outer side of the limit rod 5 is fixedly connected to a rubber ring 7 for positioning the stainless steel bowl, and the top of the rubber ring 7 is fixedly connected to an annular brush 8 for cleaning and preventing adhesion of the stainless steel bowl.

[0034] It should be noted that, in the present invention, under the elastic force of spring 1 6, the stainless steel bowl at the top is placed in the rubber ring 7, and the inner ring of the rubber ring 7 cooperates with the stainless steel bowl to position the stainless steel bowl. When the stainless steel bowl at the top is taken away, under the elastic force of spring 1 6, the stainless steel bowl at the second layer enters the rubber ring 7, and one side of the bottom of the equipment box 1 is provided with a placement groove that cooperates with the support seat 4 for positioning the support seat 4. When the vacuum suction cup 26 adsorbs the stainless steel bowl at the top of the support seat 4, the vacuum suction cup 26 pulls the stainless steel bowl at the top out of the middle of the rubber ring 7 and the annular brush 8, and the annular brush 8 cleans the outside of the stainless steel bowl. The friction between the rubber ring 7 and the annular brush 8 can prevent the stainless steel bowl at the second layer from being lifted up along with the stainless steel bowl at the top layer.

[0035] like Figure 3 , 4 As shown in Figure 5, a servo motor 19 for driving the rotating disk 9 to rotate is fixedly connected inside the equipment box 1, a hollow fixed ring 11 is fixedly connected to the top of the rotating disk 9, a hollow shaft 10 is rotatably connected to the fixed ring 11, a plurality of through holes are provided at positions of the hollow shaft 10 corresponding to the fixed ring 11, the fixed ring 11 is connected to the rotating joint in the middle of the rotating disk 9 through an air duct, and the rotating joint is connected to the vacuum pump through the air duct.

[0036] It should be noted that the vacuum pump of the present invention draws negative pressure into the fixed ring 11 through the air duct and the rotary joint. The fixed ring 11 is connected with the hollow shaft 10 through the through hole, so that the inside of the hollow shaft 10 is reset. The hollow shaft 10 is connected to the vacuum suction cup 17, so that the vacuum suction cup 17 can perform adsorption work. When the rotating disk 9 rotates, the hollow shaft 10 rotates according to the rotating disk 9 or the hollow shaft 10 needs to rotate by itself, under the cooperation of the fixed ring 11, the hollow shaft 10 and the vacuum suction cup 17 can be in a negative pressure state.

[0037] like Figure 2 , 4As shown in , 5 and 10, a driven bevel gear 12 is fixedly connected to the outside of the hollow shaft 10 and located below the rotating disk 9, a sliding rod is fixedly connected to the bottom of the sealing piston 16, the sliding rod passes through the bottom of the hollow shaft 10 and is fixedly connected to a magnet 14, a spring 15 is sleeved on the outside of the sliding rod and located between the hollow shaft 10 and the magnet 14, the electromagnetic drive unit includes an electromagnet 18, an electromagnet 18 is fixedly connected to one side of the equipment box 1 and close to the lifting plate 21, when loading and unloading, the magnet 14 is located directly above the electromagnet 18, and the magnetic pole of the electromagnet 18 when energized is the same as the magnetic pole at the bottom of the magnet 14, and the repulsive force thereof is greater than the friction force between the sealing piston 16 and the hollow shaft 10.

[0038] It should be noted that the outer side of the rotating disk 9 of the present invention corresponds to the outer side of the hollow shaft 10, and a permanent magnet is provided on the top of the equipment box 1. The magnetic switch is electrically connected to the servo motor three 19. When the permanent magnet corresponds to the magnetic switch, the driven bevel gear 12 is meshed with the driving bevel gear 36, and one of the hollow shafts 10 is located at the loading position. The hollow shaft 10 with the stainless steel bowl is located below the transverse polishing cloth wheel 37. At this time, the driven bevel gear 12 and the driving bevel gear 36 are docked and meshed after rotation. The servo motor two 13 drives the driven bevel gear 12 to rotate through the driving bevel gear 36, and the driven bevel gear 12 drives the hollow shaft 10 and the vacuum suction cup one 17 to rotate. A single-axis cylinder is provided inside the equipment box 1, and an arc-shaped rubber pad is fixed to the output end of the single-axis cylinder. When the hollow shaft 10 rotates to the loading position, the single-axis cylinder extends to squeeze and brake the hollow shaft 10 through the arc-shaped rubber pad to prevent the hollow shaft 10 from being empty. The spindle 10 rotates when the workpiece is replaced. When the vacuum suction cup 26 unloads the workpiece on the top of the hollow shaft 10, the pressure plate 28 contacts the touch switch 27 to control the electromagnet 18 to be energized. Under the action of repulsive force, the electromagnet 18 drives the driving magnet 14 to move upward, and the magnet 14 drives the sealing piston 16 to move upward inside the hollow shaft 10. The sealing piston 16 blocks the through hole of the corresponding fixing ring 11 of the hollow shaft 10, thereby blocking the negative pressure generated by the vacuum pump on the inside of the hollow shaft 10. At this time, the vacuum suction cup 26 can smoothly lift the workpiece on the top of the vacuum suction cup 17. When the touch switch 27 is separated from the pressure plate 28, the spring 2 15 drives the sealing piston 16 to slowly reset through the magnet 14. When the other vacuum suction cup 26 places the workpiece to be processed on the top of the vacuum suction cup 17, the vacuum suction cup 17 is under negative pressure at this time, and the vacuum suction cup 17 processes the workpiece for adsorption and fixation.

[0039] like Figure 2 , 3As shown in , 7, 8, 9, and 10, an L-shaped spray pipe 33 is fixedly connected to the top of the equipment box 1, and the spray pipe 33 is connected to the polishing liquid tank 2. Two support frames 34 are fixedly connected to the top of the equipment box 1. A vertical polishing cloth wheel 35 is rotatably installed in the middle of the support frame 34, and a transverse polishing cloth wheel 37 is rotatably connected to the top of the support frame 34. An active bevel gear 38 is fixedly connected to the top of the double-axis cylinder 25, and a driven bevel gear 39 is meshedly connected to the outer side of the active bevel gear 38. The driven bevel gear 39 is fixed to the support frame 34, and the transverse polishing cloth wheel 37 is slidably connected to the driven bevel gear 39 along the axial direction of the driven bevel gear 39. A sliding groove is provided at the end of the transverse polishing cloth wheel 37. The inner wall of the wheel 39 is provided with a sliding block that cooperates with the slide groove, and the reciprocating power unit includes an inclined circular plate 41. One end of the horizontal polishing cloth wheel 37 is obliquely fixedly connected to the inclined circular plate 41, and a spring three 40 is sleeved on the outer side of the horizontal polishing cloth wheel 37 and between the inclined circular plate 41 and the driven bevel gear 39. An extrusion roller 42 is installed on one side of the support frame 34 and is slidably connected to the inclined circular plate 41. It is used to drive the horizontal polishing cloth wheel 37 to rotate and reciprocate at the same time. A servo motor two 13 is fixedly connected inside the equipment box 1 and below the spray pipe 33 and below the support frame 34. The output end of the servo motor two 13 is fixedly connected to the active bevel gear 36, and the vertical polishing cloth wheel 35 is fixedly connected to the corresponding active bevel gear 36.

[0040] It should be noted that the vertical polishing cloth wheel 35 and the horizontal polishing cloth wheel 37 of the present invention are provided with two groups, one for rough polishing and the other for fine polishing. The servo motor three 19 drives the rotating disk 9 to rotate. When the magnetic switch corresponds to the permanent magnet, the hollow shaft 10 drives the workpiece to correspond to the vertical polishing cloth wheel 35. At this time, the driven bevel gear 12 is meshed with the active bevel gear 36. The servo motor two 13 drives the driven bevel gear 12 to rotate through the active bevel gear 36. The driven bevel gear 12 drives the workpiece to rotate through the vacuum suction cup one 17 of the hollow shaft 10. At the same time, the active bevel gear 36 drives the vertical polishing cloth wheel 35 rotates, and the vertical polishing cloth wheel 35 polishes the outer wall of the workpiece. The vertical polishing cloth wheel 35 drives the driven bevel gear 39 to rotate through the active bevel gear 38, and the driven bevel gear 39 drives the horizontal polishing cloth wheel 37 to rotate. During the rotation, the horizontal polishing cloth wheel 37 drives the inclined circular plate 41 to rotate. Because the inclined circular plate 41 is inclined, the inclined circular plate 41 is squeezed by the squeezing roller 42 and the spring three 40 pushes, the inclined circular plate 41 rotates and drives the horizontal polishing cloth wheel 37 to slide back and forth in the middle of the active bevel gear 38, thereby realizing the reciprocating pulling polishing of the bottom of the stainless steel bowl.

[0041] like Figure 7 , 8As shown in Figure 9, the feeding mechanism also includes a fixed frame 20 fixedly connected to one side of the equipment box body 1, two piston cylinders 29 are provided and fixedly connected to the fixed frame 20, the top of the lifting piston 32 is fixedly connected to the lifting plate 21, the top of the lifting plate 21 is rotatably connected to the rotating shaft 23, the rotating shaft 23 is movably connected to the fixed frame 20, the bottom of the lifting plate 21 is fixedly connected to a servo motor 3 for driving the rotating shaft 23 to rotate, the bottom of the lifting plate 21 is fixedly connected to a lifting cylinder 22, and the output end of the lifting cylinder 22 is connected to the fixed frame 20. The fixed frame 20 is fixed, and a cross bar 24 is fixedly connected to the top of the rotating shaft 23. A double-axis cylinder 25 is fixedly connected to one end of the top of the cross bar 24. A vacuum suction cup 26 is fixedly connected to the output end of the double-axis cylinder 25 and one end of the cross bar 24. The vacuum suction cup 26 is connected to a negative pressure generator. A pressure plate 28 is fixedly connected to the outside of the rotating shaft 23 and below the double-axis cylinder 25. A touch switch 27 is fixedly connected to the top of the fixed frame 20 and close to the side of the equipment box 1. The touch switch 27 is electrically connected to the electromagnet 18.

[0042] It should be noted that a bag conveyor is provided on one side of the support seat 4 of the present invention for conveying polished stainless steel bowls. An infrared sensor is fixedly connected to the top of the fixed frame 20 and one side close to the support seat 4. Two vacuum suction cups 26 are provided. The vacuum suction cup 26 for unloading is connected to the double-axis cylinder 25, and the vacuum suction cup 26 for loading is fixedly connected to the cross bar 24. When the hollow shaft 10 rotates to one side of the fixed frame 20, the single-axis cylinder brakes the hollow shaft 10, and the lifting cylinder 22 extends to drive the lifting plate 21 to move downward, and the lifting plate 21 drives the cross bar 24 to move downward through the rotating shaft 23. The vacuum suction cup 26 for loading contacts with the workpiece above the support seat 4 and then adsorbs it. The vacuum suction cup 26 for unloading contacts with the polished workpiece on the top of the vacuum suction cup 17 and adsorbs it, and the pressure plate 28 is equipped with a touch switch 27. When the lifting cylinder 22 is closed, the electromagnet 18 and the magnet 14 make the hollow shaft 10 to be unloaded have no negative pressure, and then the lifting cylinder 22 contracts to drive the rotating shaft 23 to rise. When the lifting cylinder 22 reaches the limit position, the servo motor 3 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the cross bar 24 to rotate so that the positions of the two vacuum suction cups 26 are swapped. When the pressure plate 28 rotates to correspond to the infrared sensor, the controller controls the double-axis cylinder 25 to extend so that the vacuum suction cup 26 for unloading is located above the conveyor. The lifting cylinder 22 drives the vacuum suction cup 26 to descend through the rotating shaft 23, so that the workpiece to be processed cooperates with the vacuum suction cup 17 for adsorption, and the polished stainless steel bowl is placed above the conveyor. Then the controller controls the vacuum suction cup 26 to separate from the workpiece, rise, and then rotate and reset, so that the double-axis cylinder 25 is located on one side above the rotating disk 9.

[0043] like Figure 7 , 8As shown in Figure 9, two one-way valves are fixed to the bottom of the piston cylinder 29, which are used for air intake and air exhaust respectively. The one-way valve for air exhaust is connected to the polishing liquid tank 2 through an air duct, and the one-way valve for air intake is connected to a filter box 30 through an air duct. The air inlet end of the filter box 30 is connected to a dust suction pipe 31, and the dust suction pipe 31 is directed toward the position of the vertical polishing cloth wheel 35.

[0044] It should be noted that, in the present invention, when the lifting plate 21 moves up and down, the lifting plate 21 drives the lifting piston 32 to move up and down inside the piston cylinder 29. The lifting piston 32 cooperates with the piston cylinder 29 to ensure the stability of the lifting of the lifting plate 21. When the lifting piston 32 moves downward, the lifting piston 32 blows the gas inside the piston cylinder 29 into the polishing liquid tank 2 through the air outlet one-way valve. Under the action of air pressure, the polishing liquid inside the polishing liquid tank 2 is sprayed onto the workpiece through the spray pipe 33. During the spraying process, the servo motor 13 drives the hollow shaft 10 below the spray pipe 33 to rotate through the active bevel gear 36. , so as to evenly spray the polishing liquid. When the lifting plate 21 drives the lifting piston 32 to move upward, the air intake check valve draws negative pressure into the filter box 30. Under the action of negative pressure, the polishing dust passes through the dust suction pipe 31 to the filter box 30. Because the filter box 30 is equipped with an air filter, the air filter purifies the internal air entering the filter box 30.
