Description

Technical Field

[0001] The present invention relates to the technical field of galvanized air duct cutting devices, and particularly to a cutting and processing device for the production of galvanized air ducts. Background Art

[0002] Galvanized air ducts are widely used in ventilation and air conditioning systems, and cutting is an important link in the production process of air ducts. Various saw blades or laser cutting devices are commonly used.

[0003] After retrieval, the invention patent with the publication number CN116689860A, titled "A Cutting and Processing Method and Device for the Production of Galvanized Air Ducts", achieves the effect of shielding the cutting space by setting a second motor, a connecting rope, and a protective cover, avoiding the phenomenon of high-temperature debris splashing during the cutting of pipes, improving the safety during the pipe cutting process, and enhancing the work safety of the staff.

[0004] However, due to the jumping and misalignment between the waste material and the galvanized sheet during the cutting of the galvanized sheet by this patented device, the cutting surface of the galvanized sheet is uneven, resulting in burrs or cracks, which affects the cutting effect of the device on the galvanized sheet. Summary of the Invention

[0005] Based on the technical problems existing in the prior art, the present invention proposes a cutting and processing device for the production of galvanized air ducts.

[0006] A cutting and processing device for the production of galvanized air ducts proposed by the present invention includes a moving block. An auxiliary mechanism is arranged inside the moving block, a cutting mechanism is arranged on the side of the auxiliary mechanism, and a transmission mechanism is arranged inside the moving block. The auxiliary mechanism includes a slot opened between two sides of the moving block. At least four lifting frames are fixedly connected to both the top inner wall and the bottom inner wall of the slot. A movable slot is opened on one side of the lifting frame. A limiting column is fixedly connected between the top inner wall and the bottom inner wall of the movable slot. A movable block is slidably connected to the circumferential side of the limiting column. A lifting block is fixedly connected between the sides of two opposite movable blocks. A rotating slot is opened at the bottom of the lifting block. A rolling column is rotatably connected between the two inner walls of the rotating slot. A spring surrounding the limiting column is fixedly connected between the top of the movable block and the top inner wall of the movable slot. A handle is fixedly connected to the outer wall of the top of the moving block.

[0007] Preferably, the cutting mechanism includes fixing plates fixedly connected to both ends of the top inner wall of the slot. A motor two is fixedly connected to one side of one of the fixing plates. The output shaft of the motor two is fixedly connected to a rotating shaft two, and the other end of the rotating shaft two is rotatably connected to one side of the other fixing plate.

[0008] Preferably, a rotating ring is slidably connected to the circumferential side surface of the second rotating shaft. A saw blade is fixedly connected to the outer wall of the circumferential side surface of the rotating ring. At least two limiting rings are rotatably connected to the outer wall of the circumferential side surface of the rotating ring, and one side of the limiting ring abuts against one side of the saw blade.

[0009] Preferably, limiting grooves are evenly formed in the circumferential side surface of the second rotating shaft. Limiting blocks aligned with the limiting grooves are evenly and fixedly connected to the inner wall of the circumferential side surface of the rotating ring, and the side surface of the limiting block is slidably connected to the inner wall of the side surface of the limiting groove.

[0010] Preferably, a lead screw aligned with the second rotating shaft is rotatably connected between the tops of the two sides of the moving block. At least two sliders are evenly threadedly connected to the circumferential side surface of the lead screw, and the top of the slider is slidably connected to the inner wall of the top of the moving block.

[0011] Preferably, a connecting block is fixedly connected to the bottom of the slider. A moving ring surrounding the second rotating shaft is fixedly connected between the two sides of the connecting block. A moving sleeve surrounding the second rotating shaft is rotatably connected to the inner wall of the circumferential side surface of the moving ring. The inner wall of the circumferential side surface of the moving sleeve is slidably connected to the circumferential side surface of the second rotating shaft, and one side of the moving sleeve is fixedly connected to one side of the rotating ring.

[0012] Preferably, a connecting frame is fixedly connected to the side surface of the connecting block. A support plate aligned with the saw blade is fixedly connected to one side of the connecting frame, and the bottom of the support plate is slidably connected to the inner wall of the bottom of the slotted opening.

[0013] Preferably, the transmission mechanism includes transmission grooves formed in the top interior and bottom interior of the moving block. At least two lifting grooves are evenly formed between the top of the transmission groove and the inner wall of the bottom of the moving block. A pressing block is slidably connected between the inner walls of the two sides of the lifting groove. At least two threaded columns aligned with the pressing block are evenly rotatably connected to the bottom of the transmission groove, and the circumferential side surface of the threaded column is threadedly connected to the inside of the pressing block.

[0014] Preferably, a first motor is fixedly connected to the top of the moving block. A first rotating shaft is fixedly connected to the output shaft of the first motor. The other end of the first rotating shaft passes through the two transmission grooves, and a chain is meshed between the circumferential side surface of the first rotating shaft and the circumferential side surface of the threaded column.

[0015] The beneficial effects of the present invention are: By means of the provided lifting block, hold the handle and move the device onto the galvanized sheet. Insert one end of the galvanized sheet between the slots. The spring pushes the movable block to move, the movable block drives the lifting block to move, and the lifting block drives the rolling column to move, causing the rolling column to press against the galvanized sheet to be cut. Start the second motor, which drives the second rotating shaft to rotate. The second rotating shaft drives the limiting block to rotate, the limiting block drives the rotating ring to rotate, and the rotating ring drives the saw blade to rotate. When the saw blade cuts the galvanized sheet, the rolling column supports the cut waste and the galvanized sheet, enabling the cut waste to remain horizontally aligned when separating from the galvanized sheet. This helps prevent the waste and the galvanized sheet from bouncing and misaligning during the cutting process by the device, which could otherwise result in an uneven cutting surface of the galvanized sheet with burrs or cracks, affecting the cutting effect of the device on the galvanized sheet.

[0016] By means of the provided moving ring, before using the device, rotate the screw rod. The screw rod drives the slider to move, the slider drives the connecting block to move, the connecting block drives the moving ring to move, the moving ring drives the moving sleeve to move, the moving sleeve drives the rotating ring to move, and the rotating ring drives the saw blade to move, enabling the device to adjust the distance between the two saw blades, thereby adjusting the cutting width when the device cuts the galvanized sheet. This is beneficial for the device to adjust according to the cutting width required when cutting the galvanized sheet, expanding the working range of the device and improving its applicability. When the connecting block moves, it drives the connecting frame to move, and the connecting frame drives the support plate to move along with the saw blade, causing the waste cut by the saw blade to move between the two support plates. The waste contacts the arc surface of the moving block at the end of the support plate, deflects, and is discharged from the device. This helps prevent the waste generated and discharged during the cutting process by the device from contacting structures such as the saw blade, which could otherwise damage the internal structure of the device and improve the safety of the device.

[0017] By means of the provided extrusion block, start the first motor. The first motor drives the first rotating shaft to rotate. The first rotating shaft drives the threaded column to rotate through a chain. The threaded column drives the extrusion block to move along the lifting groove. The extrusion block presses against the bottom of the lifting block, causing the extrusion block to push the rolling column to tightly press against the galvanized sheet. This is beneficial for the device to further avoid the bouncing and misalignment between the waste and the galvanized sheet during the cutting process of the galvanized sheet, preventing burrs on the cut galvanized sheet or breakage of the saw blade, and improving the production effect and safety of the device.

An auxiliary mechanism is arranged inside the moving block 1, a cutting mechanism is arranged on the side of the auxiliary mechanism, and a transmission mechanism is arranged inside the moving block 1. The auxiliary mechanism includes a slot 10 opened between the two sides of the moving block 1. At least four lifting frames 31 are fixedly connected to the top inner wall and the bottom inner wall of the slot 10. A movable groove 30 is opened on one side of the lifting frame 31.

A rotating groove is opened at the bottom of the lifting block 2. A rolling column 3 is rotatably connected between the two inner walls of the rotating groove. A spring 27 surrounding the limiting column 28 is fixedly connected between the top of the movable block 29 and the top inner wall of the movable groove 30.

[0021] In the present invention, the cutting mechanism includes fixing plates 9 fixedly connected to both ends of the top inner wall of the slot 10.

[0022] A rotating ring 25 is slidably connected to the circumferential side surface of the second rotating shaft 15. A saw blade 4 is fixedly connected to the outer wall of the circumferential side surface of the rotating ring 25. At least two limiting rings 26 are rotatably connected to the outer wall of the circumferential side surface of the rotating ring 25, and one side of the limiting ring 26 abuts against one side of the saw blade 4.

[0023] Limiting grooves 17 are evenly formed in the circumferential side surface of the second rotating shaft 15. Limiting blocks 24 aligned with the limiting grooves 17 are evenly and fixedly connected to the inner wall of the circumferential side surface of the rotating ring 25, and the side surface of the limiting block 24 is slidably connected to the inner wall of the side surface of the limiting groove 17.

[0024] When the present invention is in use: Hold the handle 14, move the device to the galvanized sheet, send one end of the galvanized sheet between the slots 10. The spring 27 pushes the movable block 29 to move. The movable block 29 drives the lifting block 2 to move. The lifting block 2 drives the rolling column 3 to move, so that the rolling column 3 presses against the galvanized sheet to be cut. Start the second motor 16. The second motor 16 drives the second rotating shaft 15 to rotate. The second rotating shaft 15 drives the limiting block 24 to rotate. The limiting block 24 drives the rotating ring 25 to rotate. The rotating ring 25 drives the saw blade 4 to rotate. When the saw blade 4 cuts the galvanized sheet, the rolling column 3 supports the cut waste and the galvanized sheet, so that the cut waste remains horizontally aligned when separating from the galvanized sheet, which is beneficial to preventing the waste and the galvanized sheet from jumping and misaligning during the cutting of the galvanized sheet by the device, resulting in an uneven cutting surface of the galvanized sheet and generating burrs or cracks, affecting the cutting effect of the device on the galvanized sheet.

[0025] Example 2, refer to Figures 1-4 and Figure 6 A cutting and processing device for producing galvanized air ducts, between the tops of both sides of the moving block 1, a lead screw 23 aligned with the second rotating shaft 15 is rotatably connected. At least two sliders 21 are evenly threadedly connected to the circumferential side surface of the lead screw 23, and the tops of the sliders 21 are slidably connected to the inner wall of the top of the moving block 1.

[0026] In the present invention, a connecting block 22 is fixedly connected to the bottom of the slider 21. A moving ring 19 surrounding the second rotating shaft 15 is fixedly connected between both sides of the connecting block 22. A moving sleeve 18 surrounding the second rotating shaft 15 is rotatably connected to the inner wall of the circumferential side surface of the moving ring 19. The inner wall of the circumferential side surface of the moving sleeve 18 is slidably connected to the circumferential side surface of the second rotating shaft 15. One side of the moving sleeve 18 is fixedly connected to one side of the rotating ring 25.

[0027] A connecting frame 20 is fixedly connected to the side surface of the connecting block 22. A support plate 8 aligned with the saw blade 4 is fixedly connected to one side of the connecting frame 20. The bottom of the support plate 8 is slidably connected to the inner wall of the bottom of the slot 10.

[0028] When the present invention is in use: Before using the device, rotate the lead screw 23. The lead screw 23 drives the slider 21 to move. The slider 21 drives the connecting block 22 to move. The connecting block 22 drives the moving ring 19 to move. The moving ring 19 drives the moving sleeve 18 to move. The moving sleeve 18 drives the rotating ring 25 to move. The rotating ring 25 drives the saw blade 4 to move, enabling the device to adjust the distance between the two saw blades 4, thereby adjusting the cutting width when the device cuts galvanized sheets. This is beneficial for the device to adjust according to the cutting width required when cutting galvanized sheets, expanding the working range of the device and improving the applicability of the device. When the connecting block 22 moves, it drives the connecting frame 20 to move. The connecting frame 20 drives the support plate 8 to move along with the saw blade 4, causing the waste generated by the saw blade 4 to move along between the two support plates 8. The waste contacts the arc surface of the moving block 1 at the end of the support plate 8, deflects, and is discharged from the device. This is beneficial for preventing the waste generated and discharged during the cutting of the device from contacting structures such as the saw blade 4, resulting in damage to the internal structure of the device and improving the safety of the device.

At least two threaded columns 6 aligned with the pressing block 5 are evenly rotatably connected to the bottom of the transmission groove 11. The circumferential side surface of the threaded column 6 is threadedly connected to the inside of the pressing block 5.

[0030] In the present invention, a first motor 13 is fixedly connected to the top of the moving block 1. The output shaft of the first motor 13 is fixedly connected to a first rotating shaft 12. The other end of the first rotating shaft 12 passes through the two transmission grooves 11. A chain 32 is meshed and connected between the circumferential side surface of the first rotating shaft 12 and the circumferential side surface of the threaded column 6.

[0031] When the present invention is in use: Start the first motor 13. The first motor 13 drives the first rotating shaft 12 to rotate. The first rotating shaft 12 drives the threaded column 6 to rotate through the chain 32. The threaded column 6 drives the pressing block 5 to move along the lifting groove 7. The pressing block 5 presses against the bottom of the lifting block 2, causing the pressing block 5 to push the rolling column 3 to closely abut against the galvanized sheet. This is beneficial for the device to further avoid the occurrence of jumping misalignment between the waste and the galvanized sheet when cutting the galvanized sheet, preventing burrs from appearing on the cut galvanized sheet or the saw blade 4 from breaking, and improving the production effect and safety of the device.
