Description

Technical Field

[0001] This utility model relates to the field of electric iron soleplate processing technology, specifically a device for grinding and smoothing cast iron soleplates of electric irons. Background Technology

[0002] An electric iron is a household appliance that uses electric heat to iron clothes. It converts electrical energy into heat energy through the thermal effect of electric current, which heats the soleplate and smooths out wrinkles. During the casting process, the soleplate may have uneven or bumpy surfaces. These uneven surfaces can affect the ironing effect. By polishing, the surface of the soleplate can be smoothed to achieve the ideal flatness, thus ensuring even contact with the clothes during ironing and achieving a good ironing effect.

[0003] The existing cast iron soleplate grinding device mainly consists of a worktable, a clamp, and a grinding mechanism. When grinding the soleplate, the cast iron soleplate is first placed on the worktable and fixed by a clamp to ensure that the soleplate will not move during the grinding process. Then, the drive motor is started to make the grinding head rotate at high speed. The grinding head contacts the surface of the soleplate, thereby grinding the soleplate flat.

[0004] Existing cast iron soleplate grinding devices rely solely on unidirectional grinding, failing to combine rolling and lateral movement grinding simultaneously. This results in incomplete surface coverage, leading to either insufficient or excessive grinding in certain areas. Furthermore, existing grinding devices lack flatness detection capabilities, making it impossible to assess the flatness of the ground surface during grinding. Reliance on operator experience and visual inspection further contributes to incomplete or excessive grinding, impacting both quality and efficiency. Therefore, this paper proposes a new cast iron soleplate grinding device to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a device for grinding the cast iron soleplate of an electric iron.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A grinding device for cast iron soleplate of an electric iron, comprising a worktable, a fixed groove on the worktable, two U-shaped frames fixedly connected to the top side of the worktable, each U-shaped frame having a sliding groove, a sliding rod slidably mounted in each sliding groove, a fixed collar fixedly connected between the two sliding rods, a movable rod slidably mounted within the fixed collar, an anti-detachment cap fixedly connected to the top of the movable rod, a mounting frame fixedly connected to the bottom of the movable rod, a spring fixedly connected between the mounting frame and the fixed collar, and the spring sleeved on the movable rod, a grinding wheel mounted within the mounting frame via a rotating shaft, a motor mounted on one side wall of the mounting frame, the output end of the motor connected to one end of the rotating shaft, a fixed electrode post mounted on the top side of the fixed collar, and a movable electrode post mounted on the bottom side of the anti-detachment cap. The electrode post has an indicator light installed on the top side of the anti-slip cap, and the indicator light, fixed electrode post, and movable electrode post are electrically connected. Two connecting plates are fixed between the two U-shaped frames, and a pneumatic cylinder is installed on one of the connecting plates. The working end of the pneumatic cylinder is equipped with a pneumatic rod, and the end of the pneumatic rod is fixed to a fixed collar. When grinding the cast iron soleplate of the electric iron, the grinding wheel is driven to rotate by the motor to achieve rolling grinding. At the same time, the pneumatic cylinder pushes the fixed collar to move laterally, so that the grinding wheel moves laterally while rolling itself, which can better cover the grinding surface of the soleplate, ensuring the comprehensiveness and uniformity of grinding and improving the grinding quality. During the grinding process, the preload of the spring causes the mounting frame to move the grinding wheel downward, ensuring that the grinding wheel has a good contact state with the grinding surface, which is conducive to improving grinding efficiency and effect, and making it easier to achieve the flatness requirement of the soleplate surface.

[0007] Through the reaction force of the spring and the contact mechanism of the electrode post, the indicator light can provide real-time feedback on whether the polished surface is flat. When the indicator light flashes continuously, it means that the polishing is complete; when the flashing is intermittent, polishing can continue until the flatness requirement is met. It can detect the flatness of the surface of the base plate in real time and accurately, so as to make timely adjustments to the polishing operation and ensure the polishing quality.

[0008] Preferably, U-shaped tubes are fixedly connected to both sides of the mounting frame, and multiple nozzles are connected to the U-shaped tubes. A horizontal plate is fixed to one side wall of the workbench, and a pump body is installed on the bottom side of the horizontal plate. A liquid extraction pipe is connected between the inlet of the pump body and the collection tank, and a filter screen is installed inside the port of the liquid extraction pipe, which is located inside the collection tank. A delivery pipe is connected to the outlet of the pump body, and the other end of the delivery pipe is connected to the U-shaped tube. Multiple leakage outlets are provided on the workbench, and a collection tank is installed on the bottom side of the workbench. A drain hole is provided at the bottom, and a drain pipe is fixedly connected to the end of the drain hole. During the grinding process, the water in the collection tank is transported to the nozzle by the pump body to spray the grinding surface. This can effectively reduce the dust generated during the grinding process, improve the working environment, and at the same time, the sprayed water can also cool the grinding surface and grinding wheel, preventing the base plate from deforming or the grinding wheel from being damaged due to high temperature, and further improving the grinding quality. A filter screen is installed at the end of the liquid extraction pipe to filter the return water, realize the recycling of water, reduce water waste, and prevent impurities from entering the system, ensuring the spraying effect.

[0009] Preferably, a control panel is installed on one side wall of the workbench. The control panel is used to control the start and stop of the motor, pneumatic cylinder and pump body. When using this device, by setting up the control panel, the drive equipment can be integrated into one control panel. Operators do not need to operate these devices separately in multiple locations, which greatly simplifies the operation process and improves work efficiency.

[0010] The advantages of this utility model are:

[0011] 1. This utility model achieves rolling grinding by driving the grinding wheel to rotate with an electric motor, while a pneumatic cylinder pushes the fixed collar to move laterally, so that the grinding wheel moves laterally while rolling, which can better cover the grinding surface of the base plate, ensuring the comprehensiveness and uniformity of grinding and improving the grinding quality; during the grinding process, the preload of the spring causes the mounting bracket to move the grinding wheel downward, ensuring that the grinding wheel has a good contact state with the grinding surface, which is conducive to improving grinding efficiency and effect, and making it easier for the base plate surface to achieve the required flatness;

[0012] 2. This utility model uses the reaction force of the spring and the contact mechanism of the electrode post to provide real-time feedback on whether the polished surface is flat. When the indicator light flashes continuously, it means that the polishing is complete; when the flashing is intermittent, polishing can continue until the flatness requirement is met. It can detect the flatness of the surface of the base plate in real time and accurately, which facilitates timely adjustment of the polishing operation and ensures the polishing quality.

[0013] 3. This utility model uses a pump to deliver water from the collection tank to the spray nozzle, spraying the grinding surface. This effectively reduces dust generated during grinding, improves the working environment, and cools the grinding surface and grinding wheel, preventing deformation of the base plate or damage to the grinding wheel due to high temperatures, thus further improving grinding quality. A filter screen is installed at the end of the liquid extraction pipe to filter the return water, enabling water recycling, reducing water waste, and preventing impurities from entering the system, ensuring the spraying effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 As shown, a device for grinding the cast iron soleplate of an electric iron includes a worktable 1 with a fixed groove 2. Two U-shaped frames 3 are fixedly connected to the top side of the worktable 1. Each U-shaped frame 3 has a sliding groove 4, and a sliding rod 5 is slidably fitted into each of the two sliding grooves 4. A fixed collar 6 is fixedly connected between the two sliding rods 5, and a movable rod 7 is slidably fitted into the fixed collar 6. An anti-detachment cap 8 is fixedly connected to the top of the movable rod 7, and a mounting frame 9 is fixedly connected to the bottom of the movable rod 7. A spring 10 is fixedly connected between the mounting frame 9 and the fixed collar 6, and the spring 10 is sleeved on the movable rod 7. A grinding wheel 11 is mounted inside the mounting frame 9 via a rotating shaft. A motor 12 is mounted on one side wall of the mounting frame 9, and the output end of the motor 12 is connected to one end of the rotating shaft. A fixed electrode post 14 is mounted on the top side of the fixed collar 6. A movable electrode post 13 is installed on the bottom side of the cap removal 8, and an indicator light 15 is installed on the top side of the anti-cap removal 8. The indicator light 15, the fixed electrode post 14 and the movable electrode post 13 are electrically connected. Two connecting plates 16 are fixedly connected between the two U-shaped frames 3. A pneumatic cylinder 17 is installed on one of the connecting plates 16. The working end of the pneumatic cylinder 17 is equipped with a pneumatic rod, and the end of the pneumatic rod is fixedly connected to the fixed collar 6. When working, when grinding the cast iron soleplate of the electric iron to make it flat, in order to improve the grinding effect of the soleplate, the cast iron soleplate is placed in the stepped fixed groove 2, so that the surface to be ground of the cast iron soleplate of the electric iron is facing upward. When grinding, since the spring 10 has a certain preload, under the rebound force of the spring 10, its reaction force can push the mounting frame 9 downward.

[0023] During the grinding process, the motor 12 rotates, driving the grinding wheel 11 to rotate, thus achieving rolling grinding of the base plate surface to be ground. At the same time, the pneumatic cylinder 17 operates, and the extension and retraction of the pneumatic cylinder 17 can push the fixed collar 6 to move laterally. With the cooperation of the slide rod 5, the fixed collar 6 ensures stable lateral sliding operation. This enables the mounting frame 9 and the grinding wheel 11 to move laterally, so that the grinding wheel 11 can achieve lateral grinding while rolling itself. During the grinding process, as the grinding wheel 11 moves, the surface of the base plate to be ground can be gradually ground.

[0024] Since grinding the bottom of cast iron is generally done for the manufacturing of standard parts, when grinding the upper surface of the cast iron base plate to make it flat, it means that the distance between the central axis of the grinding wheel 11 and the surface of the cast iron base plate through which the grinding wheel 11 passes is the same.

[0025] In this case, after the surface of the cast iron base plate is polished to a smooth surface, under the reaction force of the spring 10, the movable rod 7 slides downward relative to the fixed collar 6, so that the movable electrode post 13 on the bottom side of the anti-detachment cap 8 and the fixed electrode post 14 on the top side of the fixed collar 6 come into contact, which enables the indicator light 15 to be powered on and flash.

[0026] When the indicator light 15 is powered on and flashes continuously as the grinding wheel 11 slides horizontally across the upper surface of the base plate, it indicates that the grinding is complete.

[0027] When the flashing of indicator light 15 is intermittent, it means that the surface of the base plate has not been polished smooth. You can continue polishing to polish the surface of the base plate.

[0028] Please see Figure 1-2 and Figure 4-5 As shown, U-shaped tubes 18 are fixedly connected to both sides of the mounting bracket 9, and multiple nozzles 19 are connected to the U-shaped tubes 18. A horizontal plate 22 is fixedly connected to one side wall of the workbench 1, and a pump body 23 is installed on the bottom side of the horizontal plate 22. A liquid extraction pipe 24 is connected between the inlet of the pump body 23 and the collection box 20, and a filter screen is installed in the port of the liquid extraction pipe 24. The filter screen is installed in the collection box 20. The outlet of the pump body 23 is connected to a delivery pipe 25, and the other end of the delivery pipe 25 is connected to the U-shaped tube 18. Multiple drain outlets 21 are opened on the workbench 1. A collection box 20 is installed, with a drain hole at one bottom side. A drain pipe 26 is fixedly connected to the drain hole. During operation, the pump 23 draws water from the collection box 20 through the suction pipe 24 and transports it through the conveying pipe 25 to the U-shaped pipe 18. The water is then sprayed through the nozzle 19 to wet the grinding surface, reduce dust, and cool the grinding process. A filter screen is installed at the end of the suction pipe 24 to filter and circulate the returning water for better grinding results.

[0029] A control panel 27 is installed on one side wall of the workbench 1. The control panel 27 is used to control the start and stop of the motor 12, the pneumatic cylinder 17 and the pump body 23. When using the device, by setting up the control panel 27, the drive equipment can be integrated into one control panel 27. The operator does not need to operate these devices in multiple positions, which greatly simplifies the operation process and improves work efficiency.

[0030] Working Principle: Existing cast iron soleplate grinding devices rely solely on grinding in one direction, failing to combine rolling and lateral movement grinding simultaneously. This results in incomplete coverage of the grinding surface, leading to insufficient or excessive grinding in certain areas. Furthermore, existing grinding devices lack flatness detection capabilities, making it impossible to assess the flatness of the grinding surface during the grinding process. Reliance on operator experience and visual inspection further contributes to incomplete or excessive grinding, impacting grinding quality and efficiency. Therefore, this invention addresses these issues by proposing a new cast iron soleplate grinding device. To enhance the grinding effect on the cast iron soleplate, it is placed within a stepped fixing groove 2, with the grinding surface facing upwards. During grinding, the preload of spring 10 allows its rebound force to push the mounting bracket 9 downwards.

[0031] During the grinding process, the motor 12 rotates, driving the grinding wheel 11 to rotate, thus achieving rolling grinding of the base plate surface to be ground. At the same time, the pneumatic cylinder 17 operates, and the extension and retraction of the pneumatic cylinder 17 can push the fixed collar 6 to move laterally. With the cooperation of the slide rod 5, the fixed collar 6 ensures stable lateral sliding operation. This enables the mounting frame 9 and the grinding wheel 11 to move laterally, so that the grinding wheel 11 can achieve lateral grinding while rolling itself. During the grinding process, as the grinding wheel 11 moves, the surface of the base plate to be ground can be gradually ground.

[0032] Since grinding the bottom of cast iron is generally done for the manufacturing of standard parts, when grinding the upper surface of the cast iron base plate to make it flat, it means that the distance between the central axis of the grinding wheel 11 and the surface of the cast iron base plate through which the grinding wheel 11 passes is the same.

[0033] In this case, after the surface of the cast iron base plate is polished to a smooth surface, under the reaction force of the spring 10, the movable rod 7 slides downward relative to the fixed collar 6, so that the movable electrode post 13 on the bottom side of the anti-detachment cap 8 and the fixed electrode post 14 on the top side of the fixed collar 6 come into contact, which enables the indicator light 15 to be powered on and flash.

[0034] When indicator light 15 is powered on and flashes continuously as the grinding wheel 11 slides horizontally across the upper surface of the base plate, it indicates that the grinding is complete. When the flashing of indicator light 15 is intermittent, it indicates that the surface is still not smooth and the grinding operation can be continued to grind the upper surface of the base plate.

[0035] During the polishing process, under the preload of the spring 10, the polishing wheel 11 can maintain a good contact polishing state with the polishing surface, while avoiding excessive wear of the polishing wheel 11.

[0036] Mobile sanding allows for better coverage of the sanding surface of the base plate. At the same time, the flatness can be checked after sanding during the sanding process, resulting in a better sanding effect.

[0037] During the polishing process, the pump body 23 operates to draw water from the collection tank 20 through the extraction pipe 24 and transport it through the delivery pipe 25 to the U-shaped pipe 18. The water is then sprayed through the nozzle 19 to wet the polished surface and reduce polishing dust.

[0038] Simultaneously, the grinding process is cooled down. A filter screen is installed at the end of the liquid extraction pipe 24 to achieve the filtration and circulation of the return water, so as to achieve a better grinding effect.
