Description

Technical Field

[0001] This invention relates to the field of metal sheet cutting technology, specifically to a cutting and preparation equipment for antibacterial aluminum alloy sheets with maternal and infant safety grade. Background Technology

[0002] The core of cutting maternal and infant-safe antibacterial aluminum alloy sheets is to maintain the integrity of the antibacterial layer, dimensional accuracy, and no harmful residues. Cold cutting technology is preferred, and dust and secondary pollution are strictly controlled.

[0003] In the existing technology, when preparing antibacterial aluminum alloy sheets for mother and baby safety, an electric circular saw is used to cut the sheets. This results in a slow saw blade cutting speed when cutting thicker sheets, which leads to excessive local instability of the sheet, causing deformation and damage to the antibacterial layer. When cutting thin sheets, stress deformation is likely to occur, requiring high cutting quality. Summary of the Invention

During the cutting of aluminum alloy sheets by the circular saw blade and circular cutter, symmetrical rollers support the aluminum alloy sheets, preventing deformation during cutting. The storage compartment collects debris generated during cutting. When the aluminum alloy sheet is thick, a secondary cut with the circular saw blade completes the cutting while reducing blade wear and preventing breakage. The cutting method is automatically determined based on the thickness of the aluminum alloy sheet, eliminating the need for multiple manual adjustments and enabling rapid cutting. When the aluminum alloy sheet is thin, the drive motor rotates the mounting plate to switch blades. The circular cutter generates less heat during rotation, preventing deformation of thin aluminum alloy sheets due to localized overheating. Attached Figure Description

[0031] Please see Figure 1-3In this embodiment of the invention, a cutting and preparation equipment for antibacterial aluminum alloy sheets with maternal and infant safety grade includes symmetrical worktables 1. A positioning cavity 2 for placing and fixing aluminum alloy sheets is opened in the middle of the worktables 1. A fixing plate 3 is slidably connected to the upper end of one side of the worktables 1. A cutting groove 6 is opened between the symmetrical worktables 1. A cutting mechanism is provided on the side of the fixing plate 3 near the cutting groove 6. An adjustment mechanism for adjusting the position and movement state of the cutting mechanism is provided in the middle of the upper end of the worktable 1 connected to the fixing plate 3. The adjustment mechanism includes an adjustment plate 26 and a guide rod 29. When the cutting mechanism approaches the adjustment plate 26, after the guide rod 29 deflects downward, the lower part of the cutting mechanism moves away from the bottom of the inner cavity of the cutting groove 6.

[0032] A positioning plate 14 is vertically slidably connected to the inner cavity of the positioning cavity 2 near the cutting groove 6. A symmetrical electric push rod 15 is driven to the lower end of the worktable 1 near the cutting groove 6. The output end of the electric push rod 15 passes through the bottom of the worktable 1 and is fixedly connected to the lower end face of the positioning plate 14. The positioning plate 14 can be driven to move vertically in the inner cavity of the positioning cavity 2 by the symmetrical electric push rod 15, thereby clamping and fixing the maternal and infant safety grade antibacterial aluminum alloy sheet placed in the inner cavity of the positioning cavity 2. This ensures that the aluminum alloy sheet maintains a fixed position during the cutting process and avoids displacement of the aluminum alloy sheet during the cutting process, which would affect the cutting quality. Guide rails 11 are fixedly connected to both the upper and lower ends of the worktable 1 connected to the fixing plate 3. A moving block 10 is slidably connected to the middle of the side of the guide rail 11 away from the worktable 1.

[0033] A screw 12 is threadedly connected to the middle of the side of the movable block 10 away from the guide rail 11. The screw 12 is rotatably connected to the middle of both ends of the guide rail 11. Servo motors are driven to both the upper and lower ends of the worktable 1 connected to the fixed plate 3. The output end of the servo motor is fixedly connected to the end of the screw 12 near the fixed plate 3. By driving the screw 12 to rotate through the servo motor, the movable block 10 can be driven to move horizontally back and forth on the guide rail 11. The movable block 10 located at the top is fixedly connected to the side of the fixed plate 3 away from the cutting groove 6. Therefore, when the movable block 10 located at the top moves, it will drive the fixed plate 3 and the cutting mechanism to move synchronously, thereby completing the positioning of the positioning cavity 2. The aluminum alloy sheet in the inner cavity is cut, and the lower end of the moving block 10 is fixedly connected to the connecting rod 13. The lower end of the connecting rod 13 is fixedly connected to the storage compartment 9. The bottom of the electric push rod 15 is higher than the lower end of the connecting rod 13. Therefore, during the horizontal movement of the moving block 10 and the connecting rod 13, the connecting rod 13 will not come into contact with the electric push rod 15. The upper two sides of the storage compartment 9 are slidably connected to the lower ends of the two worktables 1 respectively. The horizontal width of the storage compartment 9 is greater than the width of the cutting groove 6. So when the symmetrical servo motors drive the symmetrical screws to rotate at the same time, the fixed plate 3 and the storage compartment 9 will move at the same time and the same distance.

[0034] Please see Figure 4-7 The cutting mechanism includes a mounting plate 5, with a rotating rod 4 fixedly connected to the middle of the mounting plate 5. The rotating rod 4 is rotatably connected to the upper part of the fixed plate 3. A drive motor is connected to the upper part of the fixed plate 3 away from the cutting groove 6. The output end of the drive motor is fixedly connected to the rotating rod 4. When the drive motor is working, it can drive the mounting plate 5 to rotate. A circular cutter 8 is rotatably connected to one end of the mounting plate 5, and a circular saw blade 7 is slidably connected to the other end of the mounting plate 5. Different cutters can be selected for cutting according to the thickness of the aluminum alloy sheet. At this time, the drive motor rotates the mounting plate 5 180° to complete the cutting tool switching. The self-locking of the motor can prevent the cutting tool from being used. The rotating mounting plate 5 remains fixed to ensure that the position of the cutter does not change during the cutting of aluminum alloy sheets. A transmission rod 23 is rotatably connected to one end of the mounting plate 5. A circular cutter 8 is fixedly connected to the end of the transmission rod 23 away from the mounting plate 5. A moving groove 19 is opened at the end of the mounting plate 5 away from the transmission rod 23. A fixed rod 17 is slidably connected to the inner cavity of the moving groove 19. A circular saw housing 16 is fixedly connected to the end of the fixed rod 17 away from the mounting plate 5. A circular saw blade 7 is rotatably connected to the inner cavity of the circular saw housing 16 near the cutting groove 6. The circular saw housing 16 and the circular saw blade 7 together form an electric circular saw. The electric circular saw is a commonly used technical means in the prior art.

[0035] A sliding groove 21 is provided in the middle of the inner cavity of the moving groove 19. A slider 20 is slidably connected to the inner cavity of the sliding groove 21. The slider 20 and the side of the inner cavity of the sliding groove 21 near the rotating rod 4 are elastically connected by a spring 22. The spring 22 keeps the slider 20 away from the rotating rod 4. When the device is in the initial state, the circular saw blade 7 is located directly below the circular cutter 8. The center of the circular saw blade 7 coincides with the center of the storage compartment 9. The size of the circular saw blade 7 is the same as the size of the circular cutter 8. When the fixed rod 17 is located at the bottom of the inner cavity of the moving groove 19, the lower end face of the circular saw blade 7 is lower than the lower end face of the workbench 1, while the plane at the bottom of the inner cavity of the positioning cavity 2 is higher than the lower end face of the workbench 1. Therefore, after the aluminum alloy plate is placed and fixed in the inner cavity of the positioning cavity 2, the circular saw blade 7 can be moved horizontally to complete the cutting of the aluminum alloy plate.

[0036] The inner cavity of the storage compartment 9 is rotatably connected to symmetrical rollers 25. The spacing between the symmetrical rollers 25 is greater than the width of the circular saw blade 7. The top plane of the rollers 25 coincides with the bottom plane of the inner cavity of the positioning cavity 2. As the storage compartment 9 moves horizontally with the rollers 25, the symmetrical rollers 25 simultaneously contact the lower end face of the aluminum alloy sheet. While supporting the cutting edge of the aluminum alloy sheet, the rollers 25 also rotate, causing them to roll continuously along the lower end face of the sheet. Symmetrical protrusions are fixedly connected to the side walls of the rollers 25. As the storage compartment 9 cuts the sheet with the circular saw blade 7, the metal debris generated during cutting falls into the inner cavity of the storage compartment 9, thus preventing debris from flying during the rotation of the circular saw blade 7. During the rotation of the rollers 25, the protrusions come into contact with the debris accumulated in the inner cavity of the storage compartment 9, thereby agitating the debris and distributing it more evenly within the inner cavity of the storage compartment 9, improving the collection capacity of the storage compartment 9.

[0037] Please see Figure 2 , Figure 8 Because the aluminum alloy sheet placed in the inner cavity of the positioning cavity 2 is clamped and fixed by the simultaneous downward movement of the symmetrical positioning plates 14, the distance between the lower end face of the positioning plate 14 and the bottom of the inner cavity of the positioning cavity 2 will be different after clamping and fixing aluminum alloy sheets of different thicknesses. The adjusting plate 26 is fixedly connected to the workbench 1 near the 3. The adjusting plate 26 is located between the mounting plate 5 and the fixing plate 3, and its height is lower than the lower end face of the rotating rod 4. The adjusting plate 26 has a first groove 27 and a second groove 28 on the side near the cutting groove 6. The first groove 27 and the second groove 28 are parallel to each other. The length of the first groove 27 is greater than the length of the second groove 28. The vertical height of the inner cavity of the first groove 27 is the same as the vertical height of the inner cavity of the second groove 28. The length of the second groove 28 is the same as the length of the positioning cavity 2. The two ends of the first groove 27 pass through the adjusting plate 26.

[0038] Please see Figure 7-8 When the circular saw blade 7 is located below, a driven rod 18 is fixedly connected to the middle of the end of the fixed rod 17 away from the circular saw blade 7. The center of the driven rod 18 coincides with the center of the first groove 27. As the fixed plate 3 moves horizontally, the driven rod 18 enters the first groove 27 and slides along the first groove 27. The top of the inner cavity of the first groove 27 is in contact with the top of the driven rod 18, thereby restricting the position of the driven rod 18 in the vertical direction. This restricts the vertical position of the circular saw blade 7, ensuring that the circular saw blade 7 will not move in the vertical direction when cutting aluminum alloy plates, and can perform stable cutting of aluminum alloy plates. When the driven rod 18 enters the inner cavity of the second groove 28 under the guidance of the guide rod 29, the second groove 28 will also limit the position of the circular saw blade 7 after it moves upward.

[0039] Please see Figure 8-10The second slot 28 has rectangular slots at both ends, connecting the ends of the first slot 27 and the second slot 28. The upper end of the guide rod 29 is rotatably connected to the side of the inner cavity of the second slot 28 near the fixed plate 3. The guide rod 29 is located inside the rectangular slot, and its length is less than the length of the rectangular slot, and its width is less than the width of the second slot 28. The guide rod 29 is in contact with the side wall of the rectangular slot. Since the guide rod 29 can rotate within the rectangular slot to a certain extent, when the lower end of the guide rod 29 is in contact with the bottom of the inner cavity of the first slot 27, the driven rod 18, after entering the inner cavity of the first slot 27, will approach and contact the guide rod 29. At this time, because the guide rod 29 cannot continue... When the driven rod 18 rotates, it will contact the guide rod 29 and enter the inner cavity of the second slot 28 under the guidance of the guide rod 29. When the driven rod 18 enters the second slot 28, it will drive the slider 20, the circular saw housing 16 and the circular saw blade to move upward synchronously. At this time, the spring 22 is compressed and moves along the second slot 28 to the other end. The end of the second slot 28 away from the guide rod 29 has an inclined surface 31. After the driven rod 18 disengages from the inner cavity of the second slot 28, it will move downward under the action of the spring 22 and return to the inner cavity of the first slot 27 along the inclined surface 31. During the reset process, the driven rod 18 will only slide along the inner cavity of the first slot 27.

[0040] Therefore, when the driven rod 18 moves toward the inclined plane 31, it will move along the inner cavity of slot 27 or slot 28 depending on the position of the guide rod 29. During the reset process, the driven rod 18 can only move along the inner cavity of slot 27. During the reset process of the driven rod 18 along slot 27, it will contact the side of the guide rod 29 near the inclined plane 31. At this time, the driven rod 18 will push the guide rod 29 to rotate clockwise upwards without hindering the reset process of the driven rod 18. A moving rod 30 is attached to the lower part of the guide rod 29. The side away from the guide rod 29 is slidably connected to the adjusting plate 26. The inner cavity of the adjusting plate 26 is vertically slidably connected to the side near the fixed plate 3. The lower end of the guide plate 32 passes through the top of the workbench 1 and extends into the positioning cavity 2. The side of the positioning plate 14 near the guide rod 29 is fixedly connected to the horizontal rod 33. The horizontal rod 33 is fixedly connected to the guide plate 32. So when the positioning plate 14 moves vertically, it will drive the guide plate 32 to move vertically through the horizontal rod 33. The distance between the lower end face of the positioning plate 14 and the bottom of the inner cavity of the positioning cavity 2 is referred to as the movement distance of the positioning plate 14.

[0041] Please see Figure 8-12An adjusting rod 34 is fixedly connected to the middle of the end of the moving rod 30 away from the guide rod 29. A second balance groove 37 is provided at the end of the guide plate 32 near the moving rod 30. A guide groove 36 is provided at the lower end of the second balance groove 37, and a first balance groove 35 is provided at the lower end of the guide groove 36. The end of the adjusting rod 34 away from the moving rod 30 slides within the inner cavities of the first balance groove 35, the guide groove 36, and the second balance groove 37. Therefore, when the guide plate 32 moves vertically, it will drive the moving rod 30 to move horizontally via the adjusting rod 34. The horizontal movement of the moving rod 30 will... The rotation angle of the guide rod 29 is affected by the thickness of the aluminum alloy plate 14 after it is fixed. The thickness of the plate directly affects the rotation angle of the guide rod 29. Based on the thickness of the aluminum alloy plate, it can be automatically determined whether the driven rod 18 slides in the cavity of the first slot 27 or moves in the cavity of the second slot 28. The vertical distance between the top of the cavity of the second balance slot 37 and the bottom of the cavity of the first balance slot 35 is the same as the movement distance of the positioning plate 14, and this distance is equal to twice the height of the cavity of the first balance slot 35, which is half the movement distance of the positioning plate 14.

[0042] When the positioning plate 14 moves downward to clamp and fix the aluminum alloy sheet, if the thickness of the aluminum alloy sheet is greater than half of the moving distance of the positioning plate 14, then the downward movement distance of the positioning plate 14 will be less than half of its moving distance. At this time, as the guide plate 32 moves downward with the positioning plate 14, the adjusting rod 34 will always be located in the inner cavity of the balance groove 35. At this time, the bottom of the guide rod 29 will contact the bottom of the inner cavity of the first groove 27, causing the driven rod 18 to enter the inner cavity of the second groove 28. As the circular saw blade 7 moves upward, its lower end face is higher than the bottom of the aluminum alloy sheet. At this point, the circular saw blade 7 will not cut the sheet directly, but will make a single cut on the upper part of the sheet. After the driven rod 18 returns to the inner cavity of the first slot 27 through the inclined surface 31, the lower end face of the circular saw blade 7 is lower than the lower end face of the worktable 1, and similarly lower than the lower surface of the aluminum alloy sheet. During the reset process of the circular saw blade 7, the aluminum alloy sheet will be cut a second time to complete the cutting process.

[0043] Therefore, when the aluminum alloy sheet is thick, the circular saw blade 7 can be used to perform a secondary cut, which can reduce the wear of the circular saw blade 7 while completing the cutting of the aluminum alloy sheet, thereby avoiding the breakage of the circular saw blade 7. At the same time, the cutting method of the circular saw blade 7 can be automatically determined according to the thickness of the aluminum alloy sheet, without the need for multiple manual adjustments, and the cutting of the sheet can be completed quickly. When the thickness of the sheet is less than half of the moving distance of the positioning plate 14, the adjusting rod 34 is located in the inner cavity of the guide groove 36 or the balance groove 37. Then the moving rod 30 will move horizontally in the direction of the guide rod 29, thereby pushing the guide rod 29 to rotate, so that the bottom of the guide rod 29 is away from the lower end face of the first groove 27, thus losing its guiding effect on the driven rod 18. Then the driven rod 18 will move horizontally back and forth in the inner cavity of the first groove 27. During this process, the lower end face of the circular saw blade 7 is always lower than the lower end face of the aluminum alloy sheet, so that the circular saw blade 7 can complete the cutting process in a single cut.

[0044] Please see Figure 5-8 When the aluminum alloy sheet is thin, cutting it with a circular saw blade 7 may cause localized overheating and deformation, as well as stress deformation due to the high-speed rotation of the circular saw blade 7, thus affecting the quality of the cut aluminum alloy sheet. In this case, the mounting plate 5 can be rotated 180° by a drive motor to switch the cutting tools. A gear 24 is fixedly connected to the end of the transmission rod 23 away from the circular cutter 8, and a rack 38 is fixedly connected to the side of the adjusting plate 26 near the cutting groove 6. The length of the gear 24 is less than the length of the driven rod 18, so the gear 24 moves horizontally... It will not touch the adjusting plate 26. The length of the rack 38 is the same as the horizontal length of the inner cavity of the positioning cavity 2. So, as the circular cutter 8 moves horizontally with the fixed plate 3, the gear 24 and the rack 38 can drive the transmission rod 23 to rotate clockwise, thereby driving the circular cutter 8 to rotate clockwise. In the process of the circular cutter 8 cutting the thin aluminum alloy sheet, the symmetrical rollers 25 will support the lower end of the thin aluminum alloy sheet, further reducing the possibility of deformation of the aluminum alloy sheet. In addition, the heat generated by the circular cutter 8 during the rotation cutting process is also low, thus avoiding deformation of the thin aluminum alloy sheet due to local overheating.
