[0001] This utility model relates to the field of iron teapot lid processing technology, and in particular to a grinding device for processing iron teapot lids. Background Technology
[0002] As people's pursuit of quality of life increases, iron teapots are widely welcomed due to their good thermal conductivity and heat retention. As an important part of iron teapots, iron teapot lids often have problems such as burrs, flash, and incomplete fit between the iron lid and the iron teapot body after casting or stamping, which affect the product's appearance and user experience.
[0003] Currently, the polishing of iron teapot lids mostly relies on manually operated polishing machines, which is not only labor-intensive and inefficient, but also results in inconsistent polishing quality, easily causing workpiece deformation or damage, which is detrimental to industrial production.
[0004] Therefore, it is necessary to design a grinding device for processing iron teapot lids to solve the above-mentioned technical problems. Utility Model Content
[0005] In order to overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a grinding device for processing iron teapot lids.
[0006] The technical solution is as follows: A grinding device for processing iron teapot lids includes a support frame, a motor, a grinding wheel, an electric slide rail, a first slider, a sliding frame, a bidirectional screw, a knob, a second slider, a pulley, a rubber belt, and a limiting mechanism. A motor is fixedly connected to the right side of the middle of the support frame, and a grinding wheel is fixedly connected to the motor's output shaft. Electric slide rails are fixedly connected to both the upper left and right sides of the support frame. First sliders are slidably connected to both electric slide rails. A sliding frame is fixedly connected to the front of each first slider. A bidirectional screw is rotatably connected to the lower part of both sliding frames. A knob is fixedly connected to the left end of each bidirectional screw. A second slider is threadedly connected to both the left and right sides of each bidirectional screw. Each second slider is located inside the sliding frame. A pulley is fixedly connected to the motor's output shaft. Another pulley is rotatably connected to the left side of the support frame. A rubber belt is wound between the two pulleys. A limiting mechanism is provided on the left pulley.
[0007] As a further preferred embodiment, the limiting mechanism includes a limiting frame, guide rods, springs, limiting posts, and a turntable. The limiting frame is fixedly connected to the middle of the pulley and rotates on the support frame. Three guide rods are arranged in a circular array on the limiting frame, and each guide rod is slidably connected to the limiting frame. A stop is provided inside the limiting frame, and each guide rod abuts against the stop. A spring is wound around the inside of each guide rod and the end of each guide rod that is close to each other is fixedly connected to a limiting post. The left pulley is rotatably connected to the turntable, and the turntable rotates on the support frame. The turntable has grooves that cooperate with the guide rods.
[0008] As a further preferred embodiment, a vacuuming mechanism is also included. The vacuuming mechanism includes a retaining ring, a vacuum tube, a storage box, a fan, and a handle. A retaining ring is fixedly connected to the right side of the middle of the support frame, and the retaining ring surrounds the grinding wheel. A vacuum tube is fixedly connected to the upper part of the retaining ring. Multiple vacuum ports are arranged in a ring array inside the vacuum tube. A storage box is slidably placed on the right side of the middle of the support frame. A fan is connected to the right side of the vacuum tube, and the output end of the fan extends into the storage box. A handle is fixedly connected to the right side of the storage box.
[0009] As a further preferred option, it also includes a handle, which is fixedly connected to the turntable.
[0010] As a further preferred option, a protective cover is also included, with the protective cover fixedly connected to the middle of the support frame, covering the two pulleys and other locations.
[0011] As a further preferred option, the limiting post is made of rubber.
[0012] This utility model has the following advantages: 1. This utility model uses a motor to drive the grinding wheel, which is combined with an electric slide rail to control the lifting and lowering, a bidirectional screw, and a second slider to achieve the fixing and precise positioning of the iron kettle lid and automatic grinding. Compared with manual grinding, the efficiency is significantly improved, and problems such as workpiece deformation caused by uneven operating force can be avoided. The iron kettle is fixed by simple components such as guide rods and turntables. Compared with traditional manual fixing, the stability is better and the efficiency is higher.
[0013] 2. This utility model uses a suction pipe with multiple fan-shaped suction ports evenly distributed along the outer circumference of the grinding wheel. Each suction port adopts a tapered horn shape, which can form a negative pressure adsorption area when the grinding wheel rotates at high speed, accurately capturing splashed metal fragments and dust. The suction power can be automatically adjusted according to the grinding intensity. When the grinding wheel is started, the fan runs synchronously, forming a stable airflow channel in the suction pipe, which sucks the dust generated by grinding into the storage box in real time.
[0014] 3. This utility model uses a rubber limiting post to effectively buffer mechanical vibration during the grinding process, avoiding indentations or scratches on the surface of the pot body caused by rigid clamping. In the production process, it can reduce product quality problems such as product defects caused by rigid clamping. Attached Figure Description

Detailed Implementation
[0021] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] Example: A grinding device for processing iron teapot lids, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the system includes a support frame 1, a motor 2, a grinding wheel 3, an electric slide rail 4, a first slider 5, a sliding frame 6, a bidirectional screw 7, a knob 8, a second slider 9, a pulley 10, a rubber belt 11, and a limiting mechanism. The motor 2 is bolted to the right side of the middle of the support frame 1. The grinding wheel 3 is fixedly connected to the output shaft of the motor 2. Electric slide rails 4 are bolted to both the upper left and right sides of the support frame 1. First sliders 5 are slidably connected to both electric slide rails 4. A sliding frame 6 is bolted to the front of each first slider 5. A bidirectional screw 7 is rotatably connected to the lower part of both sliding frames 6. A knob 8 is welded to the left end of each bidirectional screw 7. Second sliders 9 are threaded to both the left and right sides of each bidirectional screw 7. Each second slider 9 is located inside the sliding frame 6. A pulley 10 is fixedly connected to the output shaft of the motor 2. Another pulley 10 is rotatably connected to the left side of the support frame 1. A rubber belt 11 is wound between the two pulleys 10. A limiting mechanism is provided on the left pulley 10.
[0023] like Figure 1 and Figure 4 As shown, the limiting mechanism includes a limiting frame 12, guide rods 13, springs 14, limiting posts 15, and a turntable 16. The limiting frame 12 is fixedly connected to the middle of the pulley 10. The limiting frame 12 rotates on the support frame 1. Three guide rods 13 are arranged in a ring on the limiting frame 12. Each guide rod 13 is slidably connected to the limiting frame 12. A stop is provided inside the limiting frame 12. Each guide rod 13 abuts against the stop. A spring 14 is wound around the inside of each guide rod 13 and the limiting frame 12. Each guide rod 13 has a limiting post 15 glued to one end of each guide rod 13. The limiting post 15 is made of rubber. The left pulley 10 is rotatably connected to the turntable 16, and the turntable 16 rotates on the support frame 1. The turntable 16 has a groove that cooperates with the guide rods 13.
[0024] When using this device, first place it on a flat surface, then turn the knob 8 clockwise. The knob 8 drives the bidirectional screw 7 to rotate. Because the two second sliders 9 are threadedly engaged with the bidirectional screw 7, the two second sliders 9 will move on the bidirectional screw 7 and move away from each other. Place the iron teapot lid that needs to be deburred between the two second sliders 9. Then turn the knob 8 counterclockwise. The knob 8 drives the second sliders 9 to move closer to each other on the bidirectional screw 7. Rotate the knob 8 until the two second sliders 9 clamp the iron teapot lid that needs to be deburred, thus fixing the iron teapot lid. Then start the motor 2. The output shaft of the motor 2 drives the grinding wheel 3 to rotate rapidly, and uses the electric slide rail 4 to move the first slider 5 and the sliding frame 6 downwards until the iron teapot lid that needs to be deburred comes into contact with the grinding wheel 3. The burrs on the iron teapot lid are ground smooth under the rapid rotation of the grinding wheel 3.
[0025] When it is necessary to process the iron teapot lid to fit the body of the iron teapot more closely, rotate the turntable 16 clockwise. The turntable 16 drives the three guide rods 13 and the three limiting posts 15 to move within the groove. At the same time, each spring 14 is compressed, and each limiting post 15 is no longer in contact with the stop block. Rotate the turntable 16 to a certain position, place the teapot body on the stop block, and then release the turntable 16. At this time, the springs 14 return to their original position and drive the limiting posts 15 to firmly fix the teapot body. Then, repeat the above process to fix the iron teapot lid to the second slider 9. The operation involves fixing the iron teapot lid between the two second sliders 9 on the left side, then evenly applying fine diamond powder around the iron teapot lid. The iron teapot lid is then moved into the body of the iron teapot via the electric slide rail 4. When the motor 2 is started, the output shaft of the motor 2 drives the limiting frame 12 and the body of the iron teapot to rotate through the transmission of the pulley 10 and the rubber belt 11. Through the high-speed rotation, the body of the iron teapot and the diamond powder on the iron teapot lid continuously come into contact and rub against each other, achieving a proper fit between the iron teapot lid and the iron teapot.
[0026] like Figure 1 and Figure 5 As shown, it also includes a vacuuming mechanism, which includes a fixing ring 17, a vacuum pipe 1701, a storage frame 18, a fan 19, and a handle 20. The fixing ring 17 is welded to the right side of the middle of the support frame 1. The fixing ring 17 surrounds the grinding wheel 3. The vacuum pipe 1701 is bolted to the upper part of the fixing ring 17. The vacuum pipe 1701 has multiple vacuum ports arranged in a ring array in the inner circle. The storage frame 18 is slidably placed on the right side of the middle of the support frame 1. The fan 19 is connected to and communicates with the right side of the vacuum pipe 1701. The output end of the fan 19 extends into the storage frame 18. The handle 20 is fixedly connected to the right side of the storage frame 18.
[0027] When removing burrs from an iron teapot lid, a lot of dust and waste is usually generated. At this time, the dust is sucked into the suction pipe 1701 through the suction port and the fan 19 and discharged into the storage box 18, which is specially used to collect dust. When the storage box is full of dust, pull the handle 20 to pull out the storage box 18, clean the dust, and put the storage box 18 back in its original position.
[0028] like Figure 1 Figure 4 As shown, it also includes a handle 1601, which is fixedly connected to the turntable 16. The handle 1601 on the turntable 16 makes it easier to rotate the turntable 16, and the rubber limiting post 15 makes it more secure to fix the body of the iron teapot.
[0029] like Figure 1 As shown, it also includes a protective cover 21. The protective cover 21 is fixedly connected to the middle of the support frame 1, and the protective cover 21 covers the two pulleys 10 and other positions.
