Description

Technical Field

[0001] The invention relates to the technical field of processing inner covers of electric rice cookers, and more particularly to a trimming and polishing device for the inner covers of electric rice cookers. Background Art

[0002] A rice cooker is a household appliance used to simplify the traditional rice cooking process. It automatically completes functions such as cooking and keeping rice warm through a built-in heating element and temperature control system. The design of a rice cooker usually includes an outer shell, an inner pot, a heating plate, a temperature control device and an insulation layer. Among them, the inner lid of the rice cooker is an important component. It is usually connected to the upper lid and seals the inner pot during the cooking process. The design of the inner lid may include vents that allow steam to escape during the cooking process while maintaining an appropriate internal pressure, which helps to evenly cook and mature the rice. Some rice cookers have removable inner lids, which is a design that facilitates cleaning, especially after steaming or cooking food, as the inner lid may accumulate food residues.

[0003] During the production process, the inner cover of a stainless steel rice cooker is formed by stamping a cut stainless steel plate. Therefore, the edge of the inner cover needs to be polished and trimmed to remove burrs, improve the smoothness of the side of the inner cover, and prepare for subsequent coating treatment. The polishing process is mostly done by mechanical polishing, but mechanical polishing mostly fixes the inner cover of the rice cooker and then polishes it through a grinder. There is a clamping plate on one side of the inner cover. Therefore, when polishing the edge of the inner cover of the rice cooker, the inner cover of the rice cooker needs to be adjusted, thereby reducing the polishing efficiency of the inner cover of the rice cooker.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0030] First embodiment

[0031] As attached Figure 1 , attached Figure 2 , attached Figure 5 To the attached Figure 7 As an embodiment of the present invention, the inner cover plate 6 is placed on the top of the support member 5, and the inner cover plate 6 is rotated by cooperating with the fixing device 2 and the support member 5. The first grinding wheel 114 is pushed to the side of the inner cover plate 6 by the first pushing cylinder 111, and the arc edge of the inner cover plate 6 is trimmed and polished by the first grinding wheel 114. The clip plate grinding device 3 trims and polishes the clip plate of the inner cover plate 6. The grinding device is more suitable for the inner cover of the rice cooker, and there is no need to adjust the inner cover of the rice cooker, thereby improving the production efficiency of the rice cooker.

[0032] A device for trimming and polishing the inner cover of an electric rice cooker comprises a workbench 1, a fixing device 2 being fixedly mounted on one side of the workbench 1, a clamping plate polishing device 3 being fixedly mounted on the top of the workbench 1 near the fixing device 2, a support member 5 being fixedly mounted on the top of the workbench 1, an inner cover plate 6 being placed on top of the support member 5, and a dust removal assembly 4 being fixedly mounted on the bottom of the workbench 1;

[0033] A first fixed rail 110 is fixedly installed on the side of the top of the table 11 away from the fixing device 2, a first pushing cylinder 111 is fixedly installed on one side of the first fixed rail 110, a pushing block 112 is slidably installed on the top of the first fixed rail 110, one end of the first pushing cylinder 111 is fixedly connected to one side of the pushing block 112, a first grinding motor 113 is fixedly installed on the top of the pushing block 112, a first grinding wheel 114 is provided at the bottom of the first grinding motor 113, and the first grinding wheel 114 is rotatably installed inside the pushing block 112.

[0034] As attached Figure 6 As shown, the fixing device 2 includes a fixing frame 21, which is fixedly installed on one side of the table 11. Lifting cylinders 22 are fixedly installed on both sides of the top of the fixing frame 21. A fixing plate 23 is fixedly installed on the bottom of the lifting cylinder 22. A rotating motor 24 is fixedly installed on the top of the fixing plate 23. A pressing plate 25 is provided at the bottom of the rotating motor 24. A first magnet ring 26 is fixedly installed inside the pressing plate 25. The pressing plate 25 is rotatably installed at the bottom of the fixing plate 23.

[0035] The first magnet ring 26 and the second magnet ring 56 are magnetically connected and attracted to each other, thereby increasing the tightness of the inner cover plate 6 and preventing the inner cover plate 6 from deflecting or shaking during the rotation process.

[0036] Among them, the clamping plate grinding device 3 includes two second fixed rails 31, and a second pushing cylinder 32 is fixedly installed on one side of the two second fixed rails 31. A moving block 33 is slidably installed on the top of the second fixed rail 31. One side of the second pushing cylinder 32 is fixedly connected to the side of the moving block 33. A support frame 34 is fixedly installed on the top of the moving block 33, and a moving motor 35 is fixedly installed on one side of the support frame 34. A moving screw 36 is fixedly installed on one side of the moving motor 35, and the moving screw 36 is rotatably installed inside the support frame 34.

[0037] After the first grinding wheel 114 completes grinding of the arc surface of the inner cover plate 6, the second grinding wheel 312 positions the inner cover plate 6. Subsequently, the lateral movement of the second grinding wheel 312 is controlled by moving the screw 36, and the longitudinal movement of the second grinding wheel 312 is controlled by the second pushing cylinder 32, thereby grinding the clamping plate of the inner cover plate 6.

[0038] Among them, the outer surface of the movable screw 36 is threadedly installed with a movable base 37, and the movable base 37 is slidably installed inside the support frame 34. The top of the movable base 37 is fixedly installed with a limit frame 38, and the top of the limit frame 38 is slidably installed with a movable rod 310. A buffer spring 39 is provided on one side of the inner wall of the limit frame 38, one side of the buffer spring 39 is fixedly connected to the movable rod 310, and the other side of the buffer spring 39 is fixedly connected to the inner wall of the limit frame 38. A second grinding motor 311 is fixedly installed on one side of the movable rod 310, and a second grinding wheel 312 is provided at the bottom of the second grinding motor 311, and the second grinding wheel 312 is rotatably installed at the bottom of the movable rod 310.

[0039] A buffer spring 39 is provided between the limit frame 38 and the movable rod 310 to prevent the second grinding wheel 312 from colliding with the inner cover plate 6 during movement, causing the second grinding wheel 312 to grind the inner cover plate 6 with excessive force, thereby affecting the grinding effect on the inner cover plate 6 at the junction plate.

[0040] As attached Figure 7 In one embodiment of the invention, the support member 5 includes a fixed ring 51, which is fixedly mounted on the top of the table 11. A circular groove 52 is provided on the inner wall of the fixed ring 51. A rotating frame 53 is rotatably mounted on the top of the fixed ring 51. A support rod 54 is fixedly mounted on the bottom of the rotating frame 53. A rolling wheel 55 is rotatably mounted on one side of the support rod 54. The rolling wheel 55 is rotatably mounted inside the circular groove 52. A second magnet ring 56 is embedded in the top of the rotating frame 53.

[0041] As the rolling wheel 55 rotates inside the annular groove 52, the rotating frame 53 rotates on the top of the fixed ring 51. When the pressing plate 25 squeezes the inner cover plate 6 on the top of the rotating frame 53, the pressing plate 25 is controlled to rotate by the rotating motor 24, which will cause the rotating frame 53 and the inner cover plate 6 between the rotating frame 53 and the pressing plate 25 to rotate synchronously, thereby facilitating the first grinding wheel 114 to grind the arc surface of the inner cover plate 6.

[0042] The position of the fixing ring 51 corresponds to that of the pressing plate 25 , the second magnet ring 56 is magnetically connected to the first magnet ring 26 , the inner cover plate 6 is placed on top of the rotating frame 53 , and the diameter of the rotating frame 53 is smaller than that of the inner cover plate 6 .

[0043] Second embodiment

[0044] As attached Figure 1 To the attached Figure 3 , attached Figure 5 To the attached Figure 7This is an embodiment of the present invention. On the basis of the first embodiment, due to the lack of positioning at the top of the rotating frame 53, when the inner cover plate 6 is placed on the top of the rotating frame 53, the position of the inner cover plate 6 cannot be confirmed. Therefore, when the pressing plate 25 drives the rotating frame 53 and the top inner cover plate 6 to rotate, the arc surface will have an impact. By setting the positioning rollers 19, the positioning rollers 19 at both ends are moved to both sides of the inner cover plate 6, which can achieve the limitation of the inner cover plate 6, thereby improving the accuracy of the trimming of the inner cover plate 6 and improving the production quality of the inner cover plate 6.

[0045] As attached Figure 3 As shown, the workbench 1 includes a table top 11, a supporting foot 12 is fixedly installed at the bottom of the table top 11, connecting grooves 13 are provided on both sides of the table top 11, and a sliding groove 14 is provided on the top of the table top 11. A bidirectional motor 15 is fixedly installed inside the sliding groove 14, and a bidirectional screw 16 is provided inside the bidirectional motor 15. The bidirectional screw 16 is rotatably installed inside the sliding groove 14, and the outer surfaces of both ends of the bidirectional screw 16 are threadedly connected with sliding blocks 17, and a pushing frame 18 is fixedly installed on the top of the sliding block 17, and positioning rollers 19 are rotatably installed on both sides of the top of the pushing frame 18.

[0046] Third embodiment

[0047] As attached Figure 1 To the attached Figure 4 , attached Figure 8 As an embodiment of the present invention, a dust removal component 4 is provided. When the inner cover plate 6 is polished, a negative pressure is generated inside the gas hood 41 through the operation of the fan component 48, and the waste chips from the polishing of the inner cover plate 6 are cleaned and intercepted by the filter 47 and fall into the interior of the dust box 44, making the working environment cleaner. At the same time, the waste chips are prevented from staying at the edge of the inner cover plate 6 and affecting the processing effect of the inner cover plate 6.

[0048] As attached Figure 8 As shown, the dust removal component 4 includes a gas hood 41, which is fixedly installed at the bottom of the table 11, and dust suction ports 42 are fixedly installed on both sides of the top of the gas hood 41, and a bottom frame 43 is fixedly installed at the bottom of the gas hood 41. A fan frame 46 is fixedly installed on one side of the gas hood 41, and a filter 47 is fixedly installed on the inside of the fan frame 46 close to the gas hood 41. Fan assemblies 48 are fixedly installed on both sides of the inside of the fan frame 46, and an air outlet 49 is fixedly installed on the side of the inside of the fan frame 46 away from the filter 47.

[0049] A dust box 44 is slidably mounted inside the bottom frame 43 , a fixed handle 45 is fixedly mounted on one side of the dust box 44 , and the dust suction port 42 is fixedly mounted inside the connecting groove 13 .

[0050] The two sides of the interior of the gas cover 41 are inclined surfaces, and the two dust suction ports 42 are respectively located on one side of the second grinding wheel 312 and the first grinding wheel 114 .

[0051] The working principle of the present invention is as follows: when in use, the inner cover plate 6 is placed on the top of the rotating frame 53, the bidirectional motor 15 controls the bidirectional screw 16 to rotate, the pushing frames 18 on both sides move toward each other, the positioning rollers 19 position the two sides of the inner cover plate 6 so that the center of the inner cover plate 6 stays on the top of the rotating frame 53, and the pressing plate 25 is controlled to descend by the lifting cylinder 22. A magnetic connection is generated between the first magnet ring 26 and the second magnet ring 56, and the pressing plate 25 presses the rotating frame 53 to fix the inner cover plate 6;

[0052] The first push cylinder 111 controls the push block 112 to push to the side of the inner cover plate 6, and the first grinding motor 113 is started. The first grinding wheel 114 rotates to grind the edge of the inner cover plate 6. The rotation motor 24 controls the angle at which the pressing plate 25 drives the inner cover plate 6 to rotate. The first grinding wheel 114 grinds the arc surface of the inner cover plate 6.

[0053] After the first grinding wheel 114 finishes grinding the arc surface of the inner cover plate 6, the second pushing cylinder 32 extends, and the second grinding wheel 312 moves to the connection point of the clamping plate of the inner cover plate 6. At this time, the rotating motor 24 drives the pressing plate 25 to rotate, and the clamping plate of the inner cover plate 6 stays on one side of the second grinding wheel 312. The second grinding wheel 312 positions the inner cover plate 6. Subsequently, the second grinding motor 311 controls the second grinding wheel 312 to rotate, grinds the side edge of the clamping plate of the inner cover plate 6, and moves out of the side edge of the clamping plate by controlling the longitudinal movement of the second grinding wheel 312. The moving screw 36 is controlled to rotate by the moving motor 35, and the second grinding wheel 312 moves horizontally, so that the second grinding wheel 312 grinds the other side edge of the clamping plate.

[0054] During the grinding process, negative pressure is generated inside the gas hood 41 through the operation of the fan assembly 48, and the waste chips generated by the grinding of the inner cover plate 6 are cleaned up. The chips are intercepted by the filter 47 and fall into the inside of the dust box 44, making the working environment cleaner. At the same time, the waste chips are prevented from staying at the edge of the inner cover plate 6 and affecting the processing effect of the inner cover plate 6.

[0055] Finally, a few points should be noted: the drawings of the embodiments disclosed in the present invention only involve structures related to the embodiments disclosed in the present invention. Other structures can refer to conventional designs. In the absence of conflicts, the same embodiment and different embodiments of the present invention can be combined with each other.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
