Description

Technical Field

[0001] The present invention belongs to the technical field of metal sheet processing, and particularly relates to a flattening and cutting device for processing galvanized sheets. Background Art

[0002] At present, modern flattening and cutting devices can significantly improve the cutting accuracy through automated control and high-precision mechanical design, reduce errors caused by manual operation, and the automated cutting device can achieve continuous operation, reduce manual intervention, thereby improving production efficiency. Some devices have improved the shearing efficiency of the circular shear by increasing the number of cutter head installations. Precise cutting can reduce material waste, improve the utilization rate of galvanized sheets, and thus reduce costs. The flattening and cutting device can reduce burrs and defects on the sheet surface, improve the surface quality. At the same time, by optimizing the cutting process, damage to the galvanized layer can be avoided, and the overall quality of the product can be improved. The application of automated equipment reduces the physical labor intensity of workers and improves work safety.

[0003] However, some problems are likely to occur during the processing of galvanized sheets. For example, linear dark lines or black spots may appear on the surface. Especially in subsequent processing, the purity and uniformity of the galvanized layer will also affect the processing quality. During the cutting process, if the process is improper, it may cause damage to the galvanized layer and affect its anti-corrosion performance. Laser cutting may cause the cutting section to rust, requiring additional protective measures. Some traditional equipment is not flexible enough in adjusting the cutting shape and size, making it difficult to meet diverse processing requirements, and environmental protection measures need to be taken for treatment.

[0004] In summary, we propose a flattening and cutting device for processing galvanized sheets. By optimizing the layout of internal components and the design of functional modules, the protection performance and reliability are further improved. Through the coordinated operation of the pinch roller system, elliptical pinch roller system, cutting system, and support and buffer system, efficient flattening and cutting of galvanized sheets are achieved. The pinch roller system and the elliptical pinch roller system ensure the flat conveying and flattening of the sheet through precise gear transmission. The cutting system realizes precise cutting through the drive of hydraulic rods. The support and buffer system provides a stable operating environment and protection function for the equipment. The design of the entire device is efficient, stable, and versatile, capable of meeting the processing requirements of different specifications of galvanized sheets, while reducing the maintenance cost and operation difficulty of the equipment.

[0031] As Figures 1 to 6 shown, an embodiment of the present invention provides a flattening and cutting device for galvanized sheet processing, which includes a housing 1, a workbench 2, and an equipment slot 3. The middle of the bottom end of the housing 1 is fixedly installed with the workbench 2, and an equipment slot 3 with the same width as the housing 1 is opened at the bottom end of one side of the housing 1. It includes a workbench 2 provided in the middle of the bottom end of the outer shell 1, and a device slot 3 is provided at the top of the outer shell 1. A first pinch roller 4 is movably installed at the top of the device slot 3. The first pinch roller 4 is fixedly connected to both sides of the inner wall of the outer shell 1. The first pinch roller 4 is composed of two and arranged vertically. The first pinch roller 4 and the second pinch roller 5 form a set of transmission components. The second pinch roller 5 is movably connected below the first pinch roller 4. The galvanized sheet 18 is wound inside the first pinch roller 4. The second pinch roller 5 is installed adjacent to the first pinch roller 4. A first driving gear 6 is movably installed on both sides of the first pinch roller 4, and a second driven gear 7 is movably installed on both sides of the second pinch roller 5. The first driving gear 6 and the second driven gear 7 are meshed. On the outer side of the outer shell 1, a first motor 8 is fixedly connected to one side of the first pinch roller 4. The output shaft of the first motor 8 is fixedly connected to the top of the first pinch roller 4. The output end of the first motor 8 passes through the housing of the outer shell 1 and is connected to the first driving gear 6. Connecting blocks 9 are movably installed at positions close to the housing of the outer shell 1 on both sides of the first driving gear 6 and the second driven gear 7. When the first motor 8 rotates, the first motor 8 drives the first driving gear 6 to rotate, and the first driving gear 6 drives the second driven gear 7 to rotate, thereby driving the first pinch roller 4 and the second pinch roller 5 to rotate synchronously. The connecting blocks 9 protect the first driving gear 6 and the second driven gear 7 from damaging the inside of the housing of the outer shell 1 and prevent ink from splashing into the inside of the outer shell 1; At the front ends of the first pinch roll 4 and the second pinch roll 5, a first elliptical pinch roll 10 is movably connected. Below the first elliptical pinch roll 10, a second elliptical pinch roll 11 is movably connected. On both sides of the first elliptical pinch roll 10, third driving gears 12 are movably installed. On both sides of the second elliptical pinch roll 11, fourth driven gears 13 are installed. The third driving gears 12 and the fourth driven gears 13 also form a set of transmission components. The third driving gears 12 and the fourth driven gears 13 are meshed and connected to each other. On one side of the first elliptical pinch roll 10 outside the housing 1, a second motor 14 is fixedly connected. The output shaft of the second motor 14 is fixedly connected to the top of one side of the first elliptical pinch roll 10. When the second motor 14 drives the third driving gears 12 to rotate, due to the meshing connection of the teeth of the third driving gears 12 and the fourth driven gears 13, when the third driving gears 12 and the fourth driven gears 13 rotate, affected by the tooth resistance, the second motor 14 moves in a circular motion, driving the third driving gears 12 and the fourth driven gears 13 to rotate as a whole, and then pulling one end of the galvanized sheet 18 inside the first elliptical pinch roll 10 and the second elliptical pinch roll 11. When the galvanized sheet 18 passes through the first pinch roll 4 and the second pinch roll 5 and reaches the inside of the first elliptical pinch roll 10 and the second elliptical pinch roll 11, it is flattened again by the elliptical rollers. The galvanized sheet passing through the first pinch roll 4 and the second pinch roll 5 enters the inside of the first elliptical pinch roll 10 and the second elliptical pinch roll 11. The special shape of the elliptical pinch rolls can apply uniform pressure when the sheet passes through, further flatten the sheet, avoid damage to the sheet caused by excessive local pressure, and at the same time can better remove the minute unevenness on the surface of the sheet and ensure the flatness of the sheet, ensuring that the sheet will not have problems such as stretching, wrinkling or other deformations during the processing in each stage; At the top of the workbench 2 inside the housing 1, the machine body 15 is fixedly installed. At the front end of the machine body 15, a cutting blade 16 is fixedly connected. There are multiple cutting blades 16. A partition block 17 is fixedly connected in the middle of the multiple cutting blades 16. The design of the multiple cutting blades 16 can cut multiple layers of galvanized sheets 18 simultaneously, improving work efficiency. The partition block 17 is located in the middle of the multiple cutting blades 16, which can ensure that the distance between the cutting blades 16 is fixed, thus achieving precise cutting, avoiding the offset or dislocation of the galvanized sheet 18 during the cutting process. The partition block 17 can also play a certain guiding role, keeping the cutting blade 16 stable during the cutting process, reducing the vibration of the blade, thereby improving the cutting quality and making the edge of the cut material neater and smoother. The partition block 17 can prevent the cutting blades 16 from colliding or rubbing against each other, reducing the wear of the cutting blades 16, thus prolonging the service life of the cutting blades 16 and reducing the maintenance cost of the equipment. On the top of the workbench 2, two support bars 19 are movably installed respectively, providing a stable supporting force for the galvanized sheet 18. This design can ensure that the galvanized sheet 18 remains flat during the continuous forward processing operation through multiple groups of pinch rollers, avoiding the deformation or displacement of the galvanized sheet 18 due to its own weight or external force during the processing. Since the support bars 19 are movably installed, they can be flexibly adjusted according to the size and shape of the galvanized sheet 18, thus adapting to the processing requirements of different specifications of galvanized sheets 18 and improving the versatility and applicability of the equipment. At the top of the machine body 15, a hydraulic rod 20 is movably installed. The top of the hydraulic rod 20 is fixedly installed at the bottom end inside the housing 1. The hydraulic rod 20 can make the machine body 15 drive the cutting blade 16 to move downward to cut the transmitted galvanized sheet 18, and at the same time can provide power support for the equipment. The hydraulic system has the advantages of large output force, stable movement, easy control, etc., and can meet the power requirements of the equipment during processing such as cutting and pressing. The hydraulic rod 20 can achieve precise stroke control through the hydraulic control system, thereby precisely controlling the cutting depth of the cutting blade 16, which is particularly important when processing materials of different thicknesses or materials, and can ensure the consistency and accuracy of the cutting effect. The installation position and structural design of the hydraulic rod 20 can enhance the overall stability of the equipment. During the working process, the hydraulic rod 20 can withstand large pressures and impact forces, reduce the vibration and shaking of the equipment, improve the running stability of the equipment, and prolong the service life of the equipment. At the rear end of one side of the machine body 15, a support block 21 is fixedly connected. A support rod 22 passes through the inside of the support block 21. A spring 23 is wound and sleeved inside the support rod 22, forming a buffering and shock-absorbing effect. When the equipment is impacted or vibrated by external forces during operation, the spring 23 can play a buffering and shock-absorbing role, reducing the impact of external forces on the internal structure and components of the equipment and protecting the equipment from damage. The spring 23 has an elastic restoring force. When the external force disappears, the spring 23 can automatically return to its original state, thereby driving the support rod 22 and the support block 21 back to the initial position.Implementing the automatic reset function of the device can prevent the structural position of the device from shifting due to external forces, which may affect the processing accuracy and device performance, thus ensuring the processing quality and device reliability; On both sides of the middle end inside the housing of the outer shell 1, there are sliding grooves 24 opened. Inside the two sliding grooves 24, two sliding rails 25 are fixedly installed. Inside the two sliding rails 25, a limiting rod 26 is snap-connected. At the tail end inside the outer shell 1, a support plate 27 is movably connected. At the top of the support plate 27, a support rod 22 and a spring 23 sleeved outside it are fixedly connected. Outside the cutting blade 16, a blade protective shell 28 is movably installed. The setting of the blade protective shell 28 provides safety protection for the multiple cutting blades 16 and facilitates subsequent maintenance. It is also convenient for subsequent workers to maintain and repair mechanical devices such as the machine body 15 and the cutting blade 16; At the same time, a plurality of brackets 29 are respectively fixedly installed at the device groove 3 and the bottom end of the support plate 27, providing a stable support platform for the device that flattens and cuts the galvanized sheet 18. When carrying out load-bearing operations, the stability of the machine is not affected, thus ensuring the processing quality; In summary, through the coordinated work of the pinch roller system, the elliptical pinch roller system, the cutting system, and the support and buffer system, this device realizes the efficient flattening and cutting of the galvanized sheet 18. The pinch roller system and the elliptical pinch roller system ensure the flat conveying and flattening of the sheet through precise gear transmission. The cutting system realizes precise cutting through the drive of the hydraulic rod. The support and buffer system provides a stable operating environment and protection function for the device. The design of the entire device is efficient, stable, and versatile, capable of meeting the processing requirements of different specifications of galvanized sheets 18. At the same time, it reduces the maintenance cost and operation difficulty of the device, realizes the flattening and cutting of the galvanized sheet 18, improves the efficient processing, high-quality processing, safety, modularization degree, and service life of the device. This design not only meets the high requirements for the reliability of the flattening and cutting device but also provides a strong guarantee for the long-term stable operation of the device.

[0032] It should be noted that the control of the above-mentioned first motor 8, second motor 14, and hydraulic rod 20 mechanical devices can be carried out through the controller and sensor in the existing technology to control the motion logic, facilitating the cutting and flattening operation functions of the flattening and cutting device for the galvanized sheet 18.
