Description

Technical Field

[0001] This invention belongs to the field of steel strip grinding technology, specifically, it relates to a multifunctional steel strip edge grinding machine and its usage method. Background Technology

[0002] The prior art discloses an edge processing device for steel strip processing (CN202223126966.9), which includes a support base, a support frame, guide rods and pressure blocks, etc. The support base is connected to the top of the support frame, and guide rods are slidably provided on the left and right sides of the support frame. Pressure blocks for pressing the steel strip are connected between the guide rods.

[0003] In actual use, grinding machines are fixedly installed on both sides of the support frame to grind the two side walls of the steel strip. However, when the grinding machine grinds the steel strip wall, burrs may be generated at the edges of the steel strip. After the grinding machine finishes grinding, the operator may need to deal with the burrs separately. At the same time, dirt may also stick to the surface of the ground steel strip. The surface of the ground steel strip needs to be cleaned before or after grinding.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A multifunctional steel strip edge grinding machine includes an operating table. The top surface of the operating table is equipped with a cleaning and grinding device and a conveying and lifting device. The cleaning and grinding device includes multiple sets of extrusion cleaning plates for clamping the steel strip, multiple sets of arc-shaped guide posts for guiding the steel strip, and multiple sets of scraping blades for cleaning the surface of the steel strip. The extrusion cleaning plates located on the top surface of the operating table are movably connected to the operating table. Identical scraping blades are fixedly connected to both sides of the extrusion cleaning plates. An arc-shaped guide post located on one side of the extrusion cleaning plate is fixedly connected to the extrusion cleaning plate. The conveying and lifting device includes multiple sets of ejector pins and multiple sets of conveying shafts. The ejector pins located on the top surface of the operating table are movably connected to the operating table, and the conveying shafts are rotatably connected to the operating table. The moving extrusion cleaning plates and scraping blades clean and grind the steel strip lifted by the ejector pins.

[0007] In a preferred embodiment of the present invention, the cleaning and polishing device further includes multiple sets of polishing blocks and multiple sets of semi-threaded bolts. The polishing blocks located on the top surface of the operating table are movably connected to the operating table. Multiple sets of limiting sliding grooves are opened on the surface of the polishing blocks. One side of the extrusion cleaning plate passes through the limiting sliding groove and is slidably connected to the polishing blocks. The semi-threaded bolts pass through the polishing blocks and the extrusion cleaning plate and are threadedly connected to the polishing blocks.

[0008] In a preferred embodiment of the present invention, the cleaning and polishing device further includes multiple sets of tension springs, which are embedded in the limiting sliding groove and fixedly connected to the polishing block. One end of the tension spring is fixedly connected to the extrusion cleaning plate, and the semi-threaded bolt passes through the tension spring and is threadedly connected to the polishing block.

[0009] In a preferred embodiment of the present invention, the cleaning and polishing device further includes a positive and negative spiral screw, multiple sets of movable seats, multiple sets of fixed brackets, and multiple sets of polishing machines. The movable seats located on the top surface of the operating table are movably connected to the operating table. The positive and negative spiral screws pass through the movable seats and are rotatably connected to the movable seats. The fixed brackets located on the bottom surface of the movable seats are fixedly connected to the movable seats. The bottom surface of the fixed brackets is provided with an insertion hole adapted to the polishing machine. The polishing machine is inserted into the insertion hole and detachably connected to the fixed bracket.

[0010] In a preferred embodiment of the present invention, the cleaning and polishing device further includes multiple sets of connecting rods, multiple sets of fixing bolts, and multiple sets of springs. The same connecting rods are fixedly connected to both sides of the movable seat. The fixing bolts pass through the connecting rods and springs and are threadedly connected to the polishing block. One end of the spring is fixedly connected to the polishing block, and the other end of the spring is fixedly connected to the connecting rod.

[0011] In a preferred embodiment of the present invention, the cleaning and polishing device further includes multiple sets of guide fixing rods. The guide fixing rod located on the top surface of the operating table is slidably connected to the operating table. The guide fixing rod is L-shaped. The same guide fixing rod is fixedly connected to both sides of the movable seat. The connecting rod located on the bottom surface of the guide fixing rod is fixedly connected to the guide fixing rod. The top surface of the sliding plate is provided with a guide groove adapted to the guide fixing rod. One end of the guide fixing rod is embedded in the guide groove and slidably connected to the sliding plate.

[0012] In a preferred embodiment of the present invention, the cleaning and polishing device further includes multiple sets of linear guides, lead screws, lead screw seats, and sliding plates. The lead screw located on the side of the operating table is rotatably connected to the operating table, the linear guide located on the top surface of the operating table is fixedly connected to the operating table, the sliding plate located on the top surface of the linear guide is slidably connected to the linear guide, the lead screw located on the bottom surface of the sliding plate is fixedly connected to the sliding plate, and the lead screw passes through the lead screw seat and is rotatably connected to the lead screw seat.

[0013] In a preferred embodiment of the present invention, the conveying and lifting device further includes a cylinder and lifting strips. The cylinder is fixedly connected to the operating table, the lifting strips located on the top surface of the cylinder are fixedly connected to the cylinder, and the ejector pins are located on the top surface of the lifting strips and fixedly connected to the lifting strips. The ejector pins are arranged in a linear array about the lifting strips.

[0014] A method for using a multi-functional steel strip edge grinding machine includes the following steps:

[0015] Step 1: The operator places the steel strip to be ground on the top surface of the conveyor shaft, and the steel strip is transported to the grinding area by multiple sets of rotating conveyor shafts. At this time, the rotating motor stops working, and then gas is introduced into the cylinder. The gas pushes the lifting rod to lift the lifting plate, and the lifted lifting plate pushes multiple sets of ejector pins to lift the steel strip.

[0016] Step 2: Two movable seats are symmetrically arranged. The motor drives the output end to rotate. The output end is fixedly connected to the positive and negative spiral screws. The pushed positive and negative spiral screws push the two movable seats to move closer to each other on the top surface of the sliding plate. The same guide fixing rods are fixedly connected to both sides of the movable seats. One end of the guide fixing rod is embedded in the guide groove. The pushed movable seat pushes the guide fixing rod to move. The guide fixing rod moves along the path of the guide groove on the top surface of the sliding plate. The bottom surface of the movable seat is fixedly connected to the grinding machine. The two movable seats that move closer to each other drive the two grinding machines to move closer to each other. At this time, the grinding machine channel is provided. The output shaft of the grinding machine is fixedly connected to the grinding disc. The rotating output shaft drives the grinding disc to rotate. The grinding disc grinds the wall surface of the steel strip.

[0017] Step 3: Set the two extrusion cleaning plates opposite each other and symmetrically. The two extrusion cleaning plates are pressed close to each other. The arc-shaped guide post is a quarter-circle cylinder, and the chip scraper is a right-angled triangular prism. By setting two grinding blocks opposite each other and symmetrically, the two grinding blocks are pushed close to each other. The pushed extrusion cleaning plates push the arc-shaped guide post towards the edge of the steel strip. Because the arc-shaped guide post facing the edge of the steel strip is an arc surface, the extruded steel strip will be embedded into the gap between the two extrusion cleaning plates along the arc surface of the arc-shaped guide post. At the same time, the steel strip embedded in the extrusion cleaning plates will give a push force to the arc-shaped guide posts on both sides. The arc-shaped guide posts that are pushed drive the extrusion cleaning plates to move away from the steel strip.

[0018] Step 4: Two relatively movable seats drive the grinding machine to move. A drive assembly is also set on the side of the operating table. The output shaft of the drive assembly is fixedly connected to the lead screw. When the output shaft of the drive assembly rotates, it pushes the lead screw to rotate in the lead screw seat. The rotating lead screw pushes the lead screw seat to slide on the linear rail, thereby pushing the sliding plate to slide along the top surface of the linear rail. The pushed sliding plate pushes the grinding machine to move on the operating table to grind the wall surface of the steel strip that is lifted and fixed.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. By setting two grinding blocks opposite and symmetrically, and simultaneously pushing the two grinding blocks closer together, the pushed extrusion cleaning plates push the arc-shaped guide posts towards the edge of the steel strip. Because the arc-shaped guide posts facing the edge of the steel strip are curved, the extruded steel strip will embed itself into the gap between the two extrusion cleaning plates along the arc surface of the arc-shaped guide posts. At the same time, the steel strip embedded in the extrusion cleaning plates will exert a thrust on the arc-shaped guide posts on both sides. The arc-shaped guide posts driven by the thrust will move the extrusion cleaning plates away from the surface of the steel strip. When the gap formed between the two extrusion cleaning plates is consistent with the thickness of the steel strip to be ground, the surfaces of the two extrusion cleaning plates are in close contact with the surface of the steel strip. At this time, the surface of the shaving blades is also in contact with the surface of the steel strip. By pushing the grinding blocks, the shaving blades are pushed. The pushed shaving blades clean the stains adhering to the surface of the steel strip. At the same time, there will be burrs on the edge of the steel strip after the grinding is completed. After the grinding is completed, the burrs on the edge of the steel strip need to be manually treated, which increases the workload of the operators.

[0021] 2. By symmetrically setting two adjustable grinding blocks, the spacing between the two grinding blocks can be adjusted to accommodate steel strips of different specifications. This increases the range of steel strips that the grinding machine can grind, improves the efficiency of the grinding machine, and reduces enterprise costs. However, by setting two symmetrical extrusion cleaning plates that slide relative to the grinding blocks, when the grinding blocks approach each other, they push the arc-shaped guide post to squeeze the steel strip. The center of the steel strip's thickness aligns with the center of the gap formed by the two arc-shaped guide posts, causing the steel strip to embed between the two extrusion cleaning plates. This clamps the steel strip tightly. When grinding the wall surface of the steel strip, if the steel strip is not clamped and fixed, the edge of the ground steel strip will be tilted and not level, resulting in scrapped steel strips and increased enterprise costs.

[0022] 3. By fixing identical guide rods to both sides of the movable seat, with one end of the guide rod embedded in a guide groove, the moved movable seat pushes the guide rod to move. The guide rod moves along the path of the guide groove on the top surface of the sliding plate. The bottom surface of the movable seat is fixedly connected to a grinding machine. The two movable seats that are close to each other drive the two grinding machines to move closer to each other, thus providing a channel for the grinding machines. The output shaft of the grinding machine is fixedly connected to a grinding disc. The rotating output shaft drives the grinding disc to rotate. When the grinding disc is in contact with the wall of the steel strip, the grinding disc grinds the wall of the steel strip. By setting two movable seats that move relative to each other to drive the grinding machine to move, the required grinding size can be adjusted according to product needs, thus improving the applicability of the machine.

[0023] 4. The output shaft of the drive assembly is fixedly connected to the lead screw. When the output shaft of the drive assembly rotates, it pushes the lead screw to rotate in the lead screw holder. The rotating lead screw pushes the lead screw holder to slide on the linear rail, thereby pushing the sliding plate to slide along the top surface of the linear rail. The pushed sliding plate pushes the grinding machine to move on the operating table to grind the wall surface of the steel strip that is lifted and fixed. This ensures that the ground edge is a horizontal straight line when grinding the steel strip wall, avoiding the appearance of arcs on the steel strip wall. This would require the operator to perform secondary grinding and correction of the arc edges, increasing the operator's workload. At the same time, it improves the grinding efficiency of the machine and increases the company's revenue.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0035] A multi-functional steel strip edge grinding machine and its usage method, such as Figure 1 - Figure 7 As shown, the system includes an operating table 10. The top surface of the operating table 10 is equipped with a cleaning and grinding device and a conveying and lifting device. The cleaning and grinding device includes multiple sets of extrusion cleaning plates 23 for clamping the steel strip, multiple sets of arc-shaped guide posts 24 for guiding the steel strip, and multiple sets of scraper plates 25 for cleaning the surface of the steel strip. The extrusion cleaning plates 23 located on the top surface of the operating table 10 are movably connected to the operating table 10. Identical scraper plates 25 are fixedly connected to both sides of the extrusion cleaning plates 23. The arc-shaped guide posts 24 located on one side of the extrusion cleaning plates 23 are fixedly connected to the extrusion cleaning plates 23. The conveying and lifting device includes multiple sets of ejector pins 33 and multiple sets of conveyor shafts 34. The ejector pins 33 located on the top surface of the operating table 10 are movably connected to the operating table 10, and the conveyor shafts 34 are rotatably connected to the operating table 10. The moving extrusion cleaning plates 23 and scraper plates 25 clean and grind the steel strip lifted by the ejector pins 33. The cleaning and grinding device also includes multiple sets of grinding blocks 22 and multiple sets of semi-threaded bolts 26. The grinding block 22 on the top surface of the platform 10 is movably connected to the operating platform 10. Multiple sets of limiting sliding grooves 27 are formed on the surface of the grinding block 22. One side of the extrusion cleaning plate 23 passes through the limiting sliding groove 27 and is slidably connected to the grinding block 22. A semi-threaded bolt 26 passes through the grinding block 22 and the extrusion cleaning plate 23 and is threadedly connected to the grinding block 22. The cleaning and grinding device also includes multiple sets of tension springs 30, which are embedded in the limiting sliding grooves 27 and fixedly connected to the grinding block 22. Next, one end of the tension spring 30 is fixedly connected to the extrusion cleaning plate 23, and the semi-threaded bolt 26 also passes through the tension spring 30 and is threadedly connected to the grinding block 22. The conveying lifting device also includes a cylinder 31 and a lifting strip 32. The cylinder 31 is fixedly connected to the operating table 10, and the lifting strip 32 located on the top surface of the cylinder 31 is fixedly connected to the cylinder 31. The ejector pin 33 is located on the top surface of the lifting strip 32 and is fixedly connected to the lifting strip 32. The ejector pin 33 is arranged in a linear array about the lifting strip 32.

[0036] Specifically, during use, a rotary motor is fixedly connected to the side of the operating table 10. The output shaft of the rotary motor is fixedly connected to one end of one of the conveyor shafts 34. Multiple adjacent conveyor shafts 34 are connected by a transmission belt. When the rotary motor is powered, it drives the output shaft to rotate, which in turn drives multiple conveyor shafts 34 to rotate. The operator places the steel strip to be ground on the top surface of the conveyor shaft 34, and the steel strip is conveyed to the grinding area by the rotating multiple sets of conveyor shafts 34. At this time, the rotary motor stops working, and then gas is introduced into the cylinder 31. The gas pushes the lifting rod to lift the lifting plate 32. The lifted lifting plate 32 pushes multiple sets of ejector pins 33 to lift the steel strip, thereby cleaning the steel strip through two compressions. The opposing surfaces of the plates 23 are arranged symmetrically. The two opposing extrusion cleaning plates 23 press against each other. The arc-shaped guide post 24 is a quarter-circle cylinder, and the chip scraper 25 is a right-angled triangular prism. Two grinding blocks 22 are arranged symmetrically opposite each other. When the two grinding blocks 22 are pushed together, the pushed extrusion cleaning plates 23 push the arc-shaped guide post 24 toward the edge of the steel strip. Because the arc-shaped guide post 24 toward the edge of the steel strip is arc-shaped, the extruded steel strip will embed itself into the gap between the two extrusion cleaning plates 23 along the arc surface of the arc-shaped guide post 24. At the same time, the steel strip embedded in the extrusion cleaning plate 23 will exert a pushing force on the arc-shaped guide post 24 on both sides. 24 drives the extrusion cleaning plates 23 to move away from the surface of the steel strip. When the gap between the two extrusion cleaning plates 23 is consistent with the thickness of the steel strip to be ground, the surfaces of the two extrusion cleaning plates 23 are in close contact with the surface of the steel strip. At this time, the surface of the chip scraper 25 is also in contact with the surface of the steel strip. By pushing the grinding block 22, the chip scraper 25 is pushed. The pushed chip scraper 25 cleans the dirt adhering to the surface of the steel strip. At the same time, there will be burrs on the edge of the steel strip after the grinding. After the grinding is completed, the burrs on the edge of the steel strip need to be manually removed, which increases the workload of the operator. By symmetrically setting two adjustable grinding blocks 22, the chip scraper 25 can be adjusted to remove the burrs. The spacing between the two grinding blocks 22 is adjusted to accommodate steel strips of different specifications, increasing the range of steel strips that the grinding machine can grind, improving the efficiency of the grinding machine, and reducing enterprise costs. By setting two extrusion cleaning plates 23 that are symmetrical to each other and slide relative to the grinding blocks 22, when the grinding blocks 22 approach each other, they push the arc-shaped guide post 24 to squeeze the steel strip. The center of the steel strip thickness is aligned with the center of the gap formed by the two arc-shaped guide posts 24, and the steel strip is embedded between the two extrusion cleaning plates 23, which clamp the steel strip. When grinding the wall surface of the steel strip, if the steel strip is not clamped and fixed, the edge of the ground steel strip will be tilted and not level, resulting in the scrapping of the steel strip and thus increasing the enterprise's cost expenditure.

[0037] like Figure 2 - Figure 4As shown, the cleaning and polishing device also includes multiple sets of movable seats 17, multiple sets of fixed brackets 20, and multiple sets of polishing machines 21. The movable seats 17 located on the top surface of the operating table 10 are movably connected to the operating table 10. The fixed brackets 20 located on the bottom surface of the movable seats 17 are fixedly connected to the movable seats 17. The bottom surface of the fixed brackets 20 has an insertion hole adapted to the polishing machine 21. The polishing machine 21 is inserted into the insertion hole and detachably connected to the fixed brackets 20. The cleaning and polishing device also includes multiple sets of connecting rods 19, multiple sets of fixing bolts 28, and multiple sets of springs 29. The same connecting rods 19 are fixedly connected to both sides of the movable seats 17. The fixing bolts 28 pass through the connecting rods 19 and springs 29 and are threadedly connected to the polishing block 22. One end of the spring 29 is fixedly connected to the polishing block 22, and the other end of the spring 29 is fixedly connected to the connecting rod 19. The device also includes multiple sets of guide fixing rods 18. The guide fixing rod 18 located on the top surface of the operating table 10 is slidably connected to the operating table 10. The guide fixing rod 18 is L-shaped. The same guide fixing rod 18 is fixedly connected to both sides of the movable seat 17. The connecting rod 19 located on the bottom surface of the guide fixing rod 18 is fixedly connected to the guide fixing rod 18. The cleaning and polishing device also includes multiple sets of linear rails 11, lead screws 12, lead screw seats 13 and sliding plates 14. The lead screw 12 located on the side of the operating table 10 is rotatably connected to the operating table 10. The linear rail 11 located on the top surface of the operating table 10 is fixedly connected to the operating table 10. The sliding plate 14 located on the top surface of the linear rail 11 is slidably connected to the linear rail 11. The lead screw seat 13 located on the bottom surface of the sliding plate 14 is fixedly connected to the sliding plate 14. The lead screw 12 passes through the lead screw seat 13 and is rotatably connected to the lead screw seat 13.

[0038] Specifically, in use, a motor is fixedly connected to the top surface of the sliding plate 14. The output end of the motor is fixedly connected to the positive and negative spiral screw 16, dividing the positive and negative spiral screw 16 into two equal parts. One part of the surface of the positive and negative spiral screw 16 is provided with a left-hand thread, and the other part of the surface of the positive and negative spiral screw 16 is provided with a right-hand thread. The positive and negative spiral screw 16 passes through two movable seats 17 and is rotatably connected to the movable seats 17. The two movable seats 17 are symmetrically arranged. At this time, when the motor is powered on, the motor drives the output end to rotate, and the output end is fixedly connected to the positive and negative spiral screw. 16. The pushed forward and reverse spiral screws 16 push two movable seats 17 to move closer to each other on the top surface of the sliding plate 14. Identical guide rods 18 are fixedly connected to both sides of the movable seats 17, with one end of each guide rod 18 embedded in a guide groove 15. The pushed movable seats 17 push the guide rods 18 to move, and the guide rods 18 move along the path of the guide grooves 15 on the top surface of the sliding plate 14. A grinding machine 21 is fixedly connected to the bottom surface of the movable seats 17. The two moving seats 17 moving closer to each other drive the two grinding machines 21 to move closer together. The grinding machine 21 has a channel, and the output shaft of the grinding machine 21 is fixedly connected to a grinding disc. The rotating output shaft drives the grinding disc to rotate. When the grinding disc is in contact with the wall of the steel strip, the grinding disc grinds the wall of the steel strip. The grinding machine 21 is moved by two relatively movable seats 17. The grinding size can be adjusted according to the product needs, thus improving the applicability of the machine. The side of the operating table 10 is also equipped with a drive assembly. The output shaft of the drive assembly is fixedly connected to the lead screw 12. The rotation of the output shaft of the drive assembly pushes the lead screw 12 to rotate in the lead screw seat 13. The rotating lead screw 12 pushes the lead seat 13 to slide on the linear rail 11, thereby pushing the sliding plate 14 to slide along the top surface of the linear rail 11. The pushed sliding plate 14 pushes the grinding machine 21 to move on the operating table 10 to grind the wall of the steel strip that is lifted and fixed. This ensures that the grinding edge is a horizontal straight line when grinding the steel strip wall, avoiding the appearance of arcs on the steel strip wall. This would require the operator to perform secondary grinding and correction of the arc edges, increasing the operator's workload. At the same time, it improves the grinding efficiency of the machine and increases the company's revenue.

[0039] A method for using a multi-functional steel strip edge grinding machine includes the following steps:

[0040] Step 1: The operator places the steel strip to be ground on the top surface of the conveyor shaft 34 and transports the steel strip to the grinding area through the rotating multiple sets of conveyor shafts 34. At this time, the rotating motor stops working, and then gas is introduced into the cylinder 31. The gas pushes the lifting rod to lift the lifting plate 32. The lifted lifting plate 32 pushes multiple sets of ejector pins 33 to lift the steel strip.

[0041] Step 2: Two movable seats 17 are symmetrically arranged. The motor drives the output end to rotate. The output end is fixedly connected to the positive and negative spiral screws 16. The pushed positive and negative spiral screws 16 push the two movable seats 17 to move closer to each other on the top surface of the sliding plate 14. By fixing the same guide fixing rods 18 on both sides of the movable seats 17, one end of the guide fixing rod 18 is embedded in the guide groove 15. The pushed movable seats 17 push the guide fixing rods 18 to move. The guide fixing rods 18 move along the path of the guide groove 15 on the top surface of the sliding plate 14. The bottom surface of the movable seats 17 is fixedly connected to the grinding machine 21. The two movable seats 17 that are close to each other drive the two grinding machines 21 to move closer to each other. At this time, a channel is provided for the grinding machine 21. The output shaft of the grinding machine 21 is fixedly connected to the grinding disc. The rotating output shaft drives the grinding disc to rotate. When the grinding disc is in contact with the steel strip wall, the grinding disc grinds the steel strip wall.

[0042] Step 3: The two extrusion cleaning plates 23 are arranged symmetrically with their opposite faces facing each other. The two extrusion cleaning plates 23 are pressed close to each other. The arc-shaped guide post 24 is a quarter-circle cylinder, and the chip scraper 25 is a right-angled triangular prism. By setting two grinding blocks 22 symmetrically with their opposite faces, the two grinding blocks 22 are pushed close to each other. The pushed extrusion cleaning plates 23 push the arc-shaped guide post 24 toward the edge of the steel strip. Because the arc-shaped guide post 24 toward the edge of the steel strip is an arc surface, the extruded steel strip will be embedded into the gap between the two extrusion cleaning plates 23 along the arc surface of the arc-shaped guide post 24. At the same time, the steel strip embedded in the extrusion cleaning plates 23 will give a pushing force to the arc-shaped guide posts 24 on both sides. The arc-shaped guide posts 24 that are pushed will drive the extrusion cleaning plates 23 to move away from the surface of the steel strip.

[0043] Step 4: Two relatively movable seats 17 drive the grinding machine 21 to move. The grinding size can be adjusted according to the product needs, thus expanding the machine's applicability. The side of the operating table 10 is also equipped with a connecting drive assembly. The output shaft of the drive assembly is fixedly connected to the lead screw 12. When the output shaft of the drive assembly rotates, it pushes the lead screw 12 to rotate in the lead screw seat 13. The rotating lead screw 12 pushes the lead screw seat 13 to slide on the linear rail 11, thereby pushing the sliding plate 14 to slide along the linear rail 11 on the top surface of the linear rail 11. The pushed sliding plate 14 pushes the grinding machine 21 to move on the operating table 10, grinding the wall surface of the steel strip that is lifted and fixed.

[0044] Working principle: A rotary motor is fixedly connected to the side of the operating table 10. The output shaft of the rotary motor is fixedly connected to one end of one of the conveyor shafts 34. Multiple adjacent conveyor shafts 34 are connected by a transmission belt. When the rotary motor is powered, it drives the output shaft to rotate, which in turn drives multiple conveyor shafts 34 to rotate. The operator places the steel strip to be ground on the top surface of the conveyor shaft 34, and the steel strip is conveyed to the grinding area by the rotating multiple sets of conveyor shafts 34. At this time, the rotary motor stops working, and then gas is introduced into the cylinder 31. The gas pushes the lifting rod to lift the lifting plate 32. The lifted lifting plate 32 pushes multiple sets of ejector pins 33 to lift the steel strip. By setting the opposite faces of the two extrusion cleaning plates 23 to face each other and symmetrically, the opposite two... The extrusion cleaning plates 23 are pressed close to each other. The arc-shaped guide post 24 is a quarter-circle cylinder, and the chip scraper 25 is a right-angled triangular prism. Two grinding blocks 22 are set opposite and symmetrically. When the two grinding blocks 22 are pushed close to each other, the pushed extrusion cleaning plates 23 push the arc-shaped guide post 24 towards the edge of the steel strip. Because the arc-shaped guide post 24 facing the edge of the steel strip is arc-shaped, the extruded steel strip will embed into the gap between the two extrusion cleaning plates 23 along the arc surface of the arc-shaped guide post 24. At the same time, the steel strip embedded in the extrusion cleaning plates 23 will exert a pushing force on the arc-shaped guide post 24 on both sides. The arc-shaped guide post 24, which is pushed, drives the extrusion cleaning plates 23 to move away from the surface of the steel strip. When the two extrusion cleaning plates 23 are pressed close to each other, the extrusion cleaning plates 23 are pressed close to each other. When the gap formed between the two extrusion cleaning plates 23 is consistent with the thickness of the steel strip to be ground, the surfaces of the two extrusion cleaning plates 23 are in close contact with the surface of the steel strip. At this time, the surface of the chip scraper 25 is also in contact with the surface of the steel strip. By pushing the grinding block 22, the chip scraper 25 is pushed. The pushed chip scraper 25 cleans the dirt adhering to the surface of the steel strip. At the same time, there will be burrs on the edge of the steel strip being cleaned and ground. By symmetrically setting two adjustable grinding blocks 22, the distance between the two grinding blocks 22 can be adjusted to accommodate steel strips of different specifications. This can increase the specifications of steel strips that the grinding machine can grind, improve the efficiency of the grinding machine, and reduce the cost of the enterprise. By setting the two extrusion cleaning plates 23 to slide symmetrically relative to the grinding block 22, when The grinding blocks 22, which are brought close together, push the arc-shaped guide posts 24 to squeeze the steel strip. The center of the steel strip's thickness is aligned with the center of the gap formed by the two arc-shaped guide posts 24. The steel strip is embedded between the two extrusion cleaning plates 23.

When the motor is powered on, the motor drives the output end to rotate. The output end is fixedly connected to the positive and negative spiral screws 16.The pushed forward and reverse spiral screws 16 push two movable seats 17 to move closer to each other on the top surface of the sliding plate 14. Identical guide rods 18 are fixedly connected to both sides of the movable seats 17, with one end of each guide rod 18 embedded in a guide groove 15. The pushed movable seats 17 push the guide rods 18 to move, and the guide rods 18 move along the path of the guide groove 15 on the top surface of the sliding plate 14. A grinding machine 21 is fixedly connected to the bottom surface of the movable seats 17. The two moving seats 17 moving closer together drive the two grinding machines 21 to move closer together, providing a channel for the grinding machines 21. A grinding disc is fixedly connected to the output shaft of the grinding machine 21. The rotating output shaft drives the grinding disc to rotate. When the grinding disc... When in contact with the steel strip wall, the grinding disc grinds the steel strip wall. Two relatively movable seats 17 drive the grinding machine 21 to move. The grinding dimensions can be adjusted according to product requirements. The output shaft of the drive assembly is fixedly connected to the lead screw 12. Rotation of the drive assembly's output shaft pushes the lead screw 12 to rotate within the lead screw seat 13. The rotating lead screw 12 pushes the lead screw seat 13 to slide on the linear guide 11, thereby pushing the sliding plate 14 to slide along the top surface of the linear guide 11. The pushed sliding plate 14 then moves the grinding machine 21 on the operating table 10, grinding the wall of the steel strip that is lifted and fixed, ensuring that the ground edge is a horizontal straight line during grinding.
