Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and more specifically to a steel coil cutting device with precise positioning function. Background Technology

[0002] The core function of steel coil cutting equipment is to cut rolled metal sheets into flat single sheets after uncoiling, leveling and cutting them to a fixed length.

[0003] In existing steel coil cutting equipment, the steel coil needs to be fed along the top of the equipment during laser cutting. During this process, relative sliding occurs between the bottom of the steel coil and the fixed support structure, which can easily cause friction scratches on the bottom of the steel coil, thus affecting the processing quality. At the same time, a large amount of cutting slag easily adheres to the surface of the support structure, and there is a lack of supporting cleaning structure, resulting in low efficiency for manual cleaning. In addition, the conveying, splash prevention, and slag removal processes are independent of each other, and the actions of each mechanism cannot be coordinated, making the overall operation process cumbersome and the production efficiency low. Summary of the Invention

[0004] The purpose of this invention is to provide a steel coil cutting device with precise positioning function to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel coil cutting device with precise positioning function, comprising a base and a laser cutting host mounted on top of the base, and further comprising: A conveyor, which is installed inside the base, wherein multiple sword-shaped bars are fixedly installed at equal intervals on the surface of the conveyor belt; The protective transfer mechanism includes multiple protective strips set on the top of the conveyor belt, a guide box installed on the back of the base, and a linkage component for driving the multiple protective strips to move synchronously. The protective strips are located between two adjacent scissor strips, and the multiple protective strips slide through the guide box. The anti-splash cleaning mechanism includes multiple scrapers set at the bottom of the conveyor belt and linkage rods fixedly installed on the back of the multiple scrapers. The multiple linkage rods are all connected to the linkage assembly. The scrapers are located between two adjacent scissor bars, and the multiple linkage rods are slidably installed through the guide box.

[0006] Furthermore, the base has an opening at its top, the top slats of the conveyor belt are located inside the opening, and the upper edge of the top slats of the conveyor belt is at the same horizontal level as the upper edge of the opening.

[0007] Furthermore, two positioning mechanisms are installed on the inner wall of one side of the opening. The positioning mechanism includes a first electric push rod installed at the bottom of the opening, a limiting seat fixedly installed at the extended end of the first electric push rod, and a pressure sensor installed on the inner wall of the limiting seat. The inner wall at the bottom of the limiting seat is at the same horizontal height as the upper edge of the top slat of the conveyor belt.

[0008] Furthermore, the linkage assembly includes two second electric push rods installed inside the base and a linkage frame fixedly installed at the extended ends of the two second electric push rods. The linkage frame is located behind the guide box, and the rear ends of multiple protective strips are fixedly connected to the linkage frame.

[0009] Furthermore, the outer walls on both sides of the scraper abut against the outer walls on the opposite side of the two adjacent sword grid bars, and the rear ends of the multiple linkage rods are fixedly connected to the outer wall of the linkage frame.

[0010] Furthermore, the front of the guide box is provided with multiple feeding slots, and the back of the guide box is provided with multiple scraping slots. The protective strip is arranged to pass through the feeding slots and scraping slots in sequence, and the outer wall of the protective strip is adapted to the inner wall of the scraping slot.

[0011] Furthermore, the front of the feed box is provided with multiple storage slots for storing scrapers.

[0012] Furthermore, a slag discharge mechanism is also installed inside the base. The slag discharge mechanism includes a drive shaft that is rotatably installed inside the base along its length, a reciprocating lead screw that is fixedly installed outside the drive shaft, and a motor installed on the outer wall of one side of the base. The output end of the motor is fixedly connected to one end of the drive shaft; The reciprocating lead screw is fitted with a scraper on its external thread, and the bottom of the scraper slides into the inner wall of the base.

[0013] Furthermore, slag discharge ports are provided on both sides of the bottom of the base, and slag collection boxes are provided at the bottom of both slag discharge ports.

[0014] Compared with the prior art, the steel coil cutting device with precise positioning function provided by the present invention has the following beneficial effects: By setting up a positioning mechanism, the steel coil stops moving after contacting the sensor, realizing automated and precise positioning of the steel coil to be cut, effectively avoiding cutting deviation and ensuring the processing accuracy of the workpiece; When feeding steel coils, the drive bar moves at the same speed as the steel coil, and there is no relative slippage between them, which solves the problem of friction and scratches on the bottom of the steel coil and improves the quality of steel coil processing. By setting protective strips between the movable slats, the high-temperature slag generated by laser cutting can be blocked, preventing the slag from directly contacting and damaging the conveyor belt, thus improving the durability of the equipment. By using a conveyor belt to drive the grating bars in two areas to rotate cyclically, the grating bars in the cutting area and the cleaning area can be used alternately. The protective bar and scraper can be operated synchronously by relying on the linkage component. The scraper can scrape off the waste and slag on the protective bar and discharge the waste and slag in a directional manner. The scraper can clean the outer wall of the grating bars in the cleaning area. The operation is continuous and uninterrupted, which greatly improves the overall production efficiency and ensures the safety of operation.

[0015] By centrally collecting waste and slag from different locations, the cleanliness of the working environment has been effectively improved. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example: Please refer to Figure 1 , Figure 3 and Figure 4 A steel coil cutting device with precise positioning function includes a base 1 and a laser cutting host 2 installed on the top of the base 1. The laser cutting host 2 is existing technology and can move along the length and width directions of the base 1 to flexibly cut the steel coil. It also includes a conveyor 3 installed inside the base 1. Multiple sword bars 4 are fixedly installed at equal intervals on the surface of the conveyor belt in the conveyor 3. The top of the base 1 is provided with an opening 9. The top sword bars 4 of the conveyor belt are located inside the opening 9, and the upper edge of the top sword bars 4 of the conveyor belt is at the same horizontal height as the upper edge of the opening 9. In this embodiment, the maximum outer diameter of the waste material cut off from the steel coil is set to be less than two-thirds of the distance between two adjacent sword bars 4. After passing through the leveling machine, the steel coil reaches the top of the base 1. At the same time, the conveyor 3 is controlled to run, driving the sword strips 4 on the surface of the conveyor belt to move synchronously to the right. The sword strips 4 move at the same speed as the steel coil to prevent the steel coil from moving on the stationary sword strips 4 and causing the bottom to be scratched by friction. After the steel coil is laid flat on top of the scissor bar 4, the laser cutting host 2 is controlled to cut the steel coil according to the design path. After cutting, it is reset, and the conveyor 3 is controlled to continue running. The scissor bar 4 at the top of the conveyor belt moves to the right, thereby conveying the multiple workpieces obtained by cutting to the right. There is also a conveying device on the right side of the base 1. After the workpiece at the top of the scissor bar 4 is conveyed to the top of the conveying device, it continues to be conveyed to the next station.

[0021] See Figure 1-2 Two positioning mechanisms are installed on the inner wall of one side of the opening 9. The positioning mechanism includes a first electric push rod 10 installed at the bottom of the opening 9, a limiting seat 11 fixedly installed at the extended end of the first electric push rod 10, and a pressure sensor 12 installed on the inner wall of the limiting seat 11. The inner wall at the bottom of the limiting seat 11 is at the same horizontal height as the upper edge of the top sword bar 4 of the conveyor belt. When one end of the steel coil moves to the right and reaches the top of the limit seat 11 and contacts the pressure sensor 12, the steel coil reaches the set position. The pressure sensor 12 sends a signal to the controller, which controls the leveling machine and the slitting machine used to rewind the steel coil to stop running. The steel coil at the top of the slat 4 stops moving, achieving precise positioning of the steel coil to be cut. After the steel coil is cut, the first electric push rod 10 is controlled to drive the limit seat 11 to move downward. At this time, the upper edge of the limit seat 11 is lower than the upper edge of the opening 9, so it does not affect the rightward movement of the cut workpiece. After the workpiece at the top of the slat 4 is completely removed, the first electric push rod 10 is controlled to drive the limit seat 11 to move upward and reset.

[0022] See Figures 3-7The protective transfer mechanism includes multiple protective strips 5 set on the top of the conveyor belt, a guide box 6 installed on the back of the base 1, and a linkage assembly for driving the multiple protective strips 5 to move synchronously. A door is installed at the bottom of the guide box 6 to discharge collected slag and waste. The protective strips 5 are located between two adjacent slat bars 4, and the outer walls on both sides of the protective strips 5 abut against the outer walls of the opposite sides of the two adjacent slat bars 4. Multiple protective strips 5 are slidably installed through the guide box 6. The linkage assembly includes two second electric push rods 13 installed inside the base 1 and two second electric push rods 13 fixedly installed on the base 1. The linkage frame 14 at the extended end of the push rod 13, the extended end of the second electric push rod 13 is slidably engaged with the outer wall of the base 1, the linkage frame 14 is located behind the guide box 6, the rear ends of multiple protective strips 5 are fixedly connected to the linkage frame 14, multiple feeding slots 15 are opened on the front of the guide box 6, and multiple feeding slots 15 are correspondingly opened on the back of the base 1 for passing through the protective strips 5 and the waste and slag on their tops, multiple scraping grooves 16 are opened on the back of the guide box 6, the protective strips 5 are arranged to pass through the feeding slots 15 and scraping grooves 16 in sequence, and the outer wall of the protective strips 5 is adapted to the inner wall of the scraping grooves 16; When cutting the steel coil, protective strips 5 are installed between adjacent scimitar bars 4 in the cutting area. Therefore, the slag splashed during laser cutting is blocked by the protective strips 5, preventing high-temperature slag from splashing onto the conveyor belt surface. The cut waste also falls onto the top of the protective strips 5. After the steel coil at the top of the scimitar bars 4 is cut, the two second electric push rods 13 are controlled to extend synchronously, driving the linkage frame 14 to move backward, thereby driving each protective strip 5 to move backward synchronously. During this process, the scraper grooves 16 scrape away the slag splashed onto the top of the protective strips 5 and the collected waste. Slag and waste fall along the guide box 6 and are collected. After the protective strip 5 moves backward and separates from the sword strips 4, the conveyor 3 is controlled to run. The sword strips 4 at the top of the conveyor belt move, and at the same time, the new steel coil moves to the top of the sword strips 4. The sword strips 4 in the cutting area move to the bottom of the conveyor belt, that is, the sword strips 4 in the cutting area move to the cleaning area. This realizes the alternating change of the position of the sword strips 4 in the two areas. Then, the second electric push rod 13 is controlled to drive the linkage frame 14 to move forward, and the protective strips 5 move forward and reset along the space between two adjacent sword strips 4.

[0023] In this embodiment, the conveyor belt drives the sword bar 4 a certain distance each time the conveyor 3 starts and stops. Therefore, in the design, since the distance the conveyor belt drives the sword bar 4 is greater than the actual distance the steel coil moves on the top of the base 1, the conveyor belt first drives a set distance before driving the steel coil to the right. This ensures that the conveyor belt stops moving after the steel coil moves to the set position (position of pressure sensor 12). A position sensor is installed inside the base 1 to monitor the distance the conveyor belt drives.

[0024] See Figure 3 , Figure 6 and Figure 7 The anti-splash cleaning mechanism includes multiple scrapers 7 set at the bottom of the conveyor belt and linkage rods 8 fixedly installed on the back of the multiple scrapers 7. The multiple scrapers 7 are located below multiple protective strips 5. The multiple linkage rods 8 are all connected to the linkage assembly. The scrapers 7 are located between two adjacent sword strips 4. The multiple linkage rods 8 are all slidably installed through the guide box 6. The outer walls on both sides of the scrapers 7 abut against the outer walls on the opposite side of the two adjacent sword strips 4. The rear ends of the multiple linkage rods 8 are all fixedly connected to the outer wall of the linkage frame 14. The front of the guide box 6 is also provided with multiple storage slots 17 for storing the scrapers 7. A support plate is installed inside the conveyor 3. The support plate is located at the top of the conveyor belt below the conveyor 3 to prevent the conveyor belt from deforming when cleaning the sword strips 4 below. After each of the scissor bars 4 in the cutting area moves to the cleaning area, the second electric push rod 13 is controlled to drive the linkage frame 14 to move forward. Through each linkage rod 8, each scraper 7 is driven to move forward along the space between two adjacent scissor bars 4 in the cleaning area to clean the material residue splashed on the outer wall of the scissor bars 4. When the linkage frame 14 moves backward, the scraper 7 moves backward synchronously through each linkage rod 8 until the scraper 7 is completely inside the storage groove 17, so as not to affect the movement of the subsequent sword bar 4.

[0025] See 1 and Figure 3 The base 1 is also equipped with a slag discharge mechanism. The slag discharge mechanism includes a drive shaft 18 that is rotatably installed inside the base 1 along its length, a reciprocating screw 19 that is fixedly installed outside the drive shaft 18, and a motor 20 that is installed on the outer wall of one side of the base 1. The output end of the motor 20 is fixedly connected to one end of the drive shaft 18. A scraper 21 is installed on the external thread of the reciprocating screw 19. The bottom of the scraper 21 is slidably fitted with the inner wall of the bottom of the base 1. Slag discharge ports 22 are opened on both sides of the bottom of the base 1. A slag collection box 23 is provided at the bottom of each of the two slag discharge ports 22. The slag removed from the surface of the cleaning area's slats 4 falls onto the inner wall of the bottom of the base 1, between the two slag discharge ports 22. By controlling the motor 20 to drive the transmission shaft 18 to rotate, the reciprocating screw 19 rotates accordingly, causing the scraper 21 to move back and forth along the inner wall of the bottom of the base 1. During this process, when the scraper 21 moves to the top area of ​​the slag discharge port 22, the slag on one side of the scraper 21 is cleaned into the slag collection box 23, thus achieving centralized collection of the slag.
