Description

Technical Field

[0001] This invention relates to the field of hot-dip galvanized steel strip cutting, and in particular to an automatic cutting device and method for hot-dip galvanized steel strip. Background Technology

[0002] Hot-dip galvanized steel strip is a steel product processed using a special technique. During production, ordinary steel strip is first pickled to remove surface rust and impurities. Then, it is immersed in molten zinc, causing a uniform layer of zinc to adhere to the surface. This zinc layer forms a protective film on the steel strip surface, effectively preventing oxidation during use and extending its service life. For ease of use, the steel strip needs to be cut.

[0003] However, existing steel strip cutting devices are inconvenient to clean before use. During production, the steel strip may become contaminated with impurities such as grease, dust, and oxides, which can affect the cutting effect and product quality, and increase cutting costs. Therefore, it is necessary to develop new functions for automatic cutting devices and methods for hot-dip galvanized steel strip. Summary of the Invention

A return spring is mounted on the upper right side of the hydraulic rod. Two matching wheels are mounted inside the side moving slots. The moving wheels are equipped with upper transmission gears on their outer sides, and bottom drive gears are installed at the bottom of the two upper transmission gears. The bottom drive gears mesh with the two upper transmission gears. A front drive motor is installed in front of the bottom drive gear. A mounting groove is provided inside the front mounting plate on the side away from the top rotating shaft. A rack is installed on the inner wall of the mounting groove. A moving gear that meshes with the rack is installed inside the mounting groove. A stepper motor is installed on the top of the moving gear. A laser cutting head is installed on the bottom of the moving gear. Guide plates are arrayed on the left end of the pointed block.

[0010] Preferably, the front plate forms a detachable structure with the rear plate through the cooperation between the mounting base plate, the slider and the slot, and the mounting base plate forms a locking structure with the sliding groove through the cooperation between the slot and the hole, and the dimensions between the slot and the hole match each other.

[0011] Preferably, the supporting connecting plate forms a rotating structure with the outer supporting plate through a top connecting shaft, the supporting connecting plates form a rotating structure through a middle connecting shaft, the supporting connecting plate forms a rotating structure with the rear fixed wheel through a bottom connecting shaft, and the supporting connecting plate forms a rotating structure with the outer sleeve rod through a bottom connecting shaft.

[0012] Preferably, the outer sleeve rod forms a forward and backward translation structure with the outer rod via a threaded rod, and the drive shaft forms a detachable structure with the threaded rod via an adjusting groove, with the dimensions of the drive shaft and the adjusting groove matching each other.

[0013] Preferably, the pointed blocks are arranged in an array inside the side plate, the bottom of the cleaning brush is at the same horizontal level as the top of the pointed blocks, and the cleaning brush is rotatably connected to the central mounting base.

[0014] Preferably, the upper drive wheel forms a rotating structure through the cooperation between the lower driven gear and the upper drive gear, the lower driven gear and the upper drive gear are perpendicular to each other, the transmission shaft and the lower driven gear are fixed to each other, the rear drive gear forms a rotating structure through the transmission shaft, and the lower drive wheel forms a rotating structure through the cooperation between the rear driven gear and the rear drive gear.

[0015] Preferably, the suction cup forms a lifting structure via a hydraulic rod, the hydraulic rod forms a rotating structure with the front mounting plate via a top pivot, and the hydraulic rod forms a pressing structure with the front mounting plate via a return spring.

[0016] Preferably, the upper transmission gear forms a rotating structure through the cooperation between the bottom drive gear and the front drive motor, the moving wheel forms a rotating structure through the upper transmission gear, and the front mounting plate forms a translational structure through the cooperation between the moving wheel and the side moving groove and the side plate.

[0017] Preferably, the laser cutting head forms a translation structure with the mounting groove through the cooperation between the moving gear and the rack, and the width of the mounting groove is equal to the width between the side plates.

[0018] Preferably, the steel strip coil is placed outside the outer support plate, and then the front plate is installed in front of the fixed rear plate. During this process, as the threaded rod drives the outer sleeve rod to move horizontally, the drive shaft enters the adjusting groove. Because the drive shaft and the adjusting groove are sized to match, when the drive shaft is rotated by the drive component, it drives the threaded rod behind the adjusting groove to rotate. As the threaded rod rotates, the externally engaged adjusting groove moves horizontally outside the threaded rod. During this horizontal movement, the distance between the outer sleeve rod and the rear fixed wheel changes. The central rotating shaft rotates with the outer sleeve rod via the front bottom connecting rotating shaft, and simultaneously rotates with the rear fixed wheel via the rear bottom connecting rotating shaft. At this time, the distance between the bottom connecting rotating shaft and the outer sleeve rod... This change alters the height between the top of the central shaft and the outer rod. Since the outer support plate is connected to the top of the central shaft, it can rise and fall within the device to adjust the distance to the outer rod, facilitating adjustment of the overall diameter of the outer support plates. This allows for the installation and fixing of hot-dip galvanized steel strip coils of different sizes, simplifying the uncoiling and securing of the steel strip. The steel strip is then guided into the left side of the device via the top connecting shaft. The top drive motor drives the upper drive gear to rotate, which in turn drives the lower driven gear. Because the lower driven gear is fixed to the transmission shaft, the transmission shaft also rotates within the device. This rotation of the transmission shaft drives the upper drive wheel... The drive shaft rotates, and because a rear drive gear is installed behind it, the rear drive gear rotates in the same direction as the drive shaft. Simultaneously, the rear driven gear meshes with the rear drive gear, causing it to rotate in the opposite direction. This driven gear then drives the lower drive wheel to rotate, and the lower drive wheel rotates in the same direction as the rear driven gear, but opposite to the direction of the upper drive wheel. This propels the steel belt between the upper and lower drive wheels forward, facilitating feeding. The steel belt then enters the bottom of the front mounting plate, where a stepper motor drives a moving gear to rotate inside the device. Because the moving gear meshes with a rack, it... By translating the external part, the left and right position of the laser cutting head connected at the bottom inside the device can be adjusted, facilitating the cutting of the steel strip. After the steel strip is cut once, a break is formed between the cut part and the uncut part. At this time, the suction cup moves downward under the drive of the hydraulic rod, and then the suction cup adsorbs the steel strip. After being sucked in, the break of the steel strip is lifted, and then the upper and lower drive wheels at the rear rotate to feed the material. At this time, the suction cup will rotate under the action of the top hydraulic rod, which will stretch the return spring, placing the uncut head on top of the cut steel strip. Then the suction cup is lowered, and the hydraulic rod returns to its original position under the elastic action of the return spring for the next use.

[0019] The present invention has the following beneficial effects:

[0020] During use, the user pushes the front plate, which is then installed into the slot inside the fixed rear plate via the rear mounting base plate. During the pushing process, the sliders on both sides of the mounting base plate slide in the grooves opened on the inner wall of the fixed rear plate, thereby improving the stability and smoothness of the installation process between the mounting base plate and the fixed rear plate. After installation at a suitable distance, the locking hole will engage with the inside of the locking groove to fix the position of the mounting base plate, preventing the mounting base plate from falling off the inside of the device and affecting the use of the device.

[0021] This invention uses a cleaning brush to clean the steel strip. During use, the user places the steel strip on top of the pointed block. This ensures support for the steel strip while preventing the steel strip from sticking to the support surface due to insufficient gap, which would affect the use of the device. It also prevents the steel strip from sticking to the support surface due to high temperature during the cutting process, which would also affect its use. At the same time, the cleaning brush installed on top of the pointed block can also clean the steel strip that enters the device to be cut, preventing dirt or other impurities from affecting the cutting quality.

[0022] This invention uses a suction cup to lift the steel strip. After the steel strip is cut, the cut part and the uncut part form a break. At this time, the suction cup moves downward under the drive of the hydraulic rod and then adsorbs the steel strip. After being sucked in, the break point of the steel strip is lifted. Then, the upper and lower drive wheels at the rear rotate to feed the material. At this time, the suction cup rotates under the action of the top hydraulic rod, which stretches the return spring, placing the uncut head on top of the cut steel strip. Then the suction cup is lowered, and the hydraulic rod returns to its original position under the elastic action of the return spring for the next use.

[0023] This invention uses an upper transmission gear to translate the front mounting plate. A front drive motor drives a bottom drive gear to rotate inside the device. The bottom drive gear then drives the upper transmission gears meshing on both sides to rotate. Simultaneously, the two upper transmission gears rotate in the same direction. Since a movable wheel is installed behind the upper transmission gear, the movable wheel also rotates inside the device. Therefore, the movable wheel translates inside the side movable groove, which facilitates the adjustment of the left and right position of the front mounting plate inside the device and the adjustment of the position for cutting the steel strip.

[0043] Example 2

[0044] This embodiment is based on the previous embodiment, but differs from the previous embodiment in that it provides an uncoiling assembly for an automatic cutting device for hot-dip galvanized steel strip.

[0045] The front plate 1, through the cooperation of the mounting base plate 4, slider 5, and slot 9, forms a detachable structure with the fixed rear plate 7. The mounting base plate 4, through the cooperation of the slot 9 and the slot 6, forms a locking structure with the sliding groove 8. The dimensions between the slot 6 and the slot 9 are mutually matched. During use, the user pushes the front plate 1, and then the front plate 1 is installed into the hollow groove inside the fixed rear plate 7 through the mounting base plate 4. During the pushing process, the sliders 5 on both sides of the mounting base plate 4 slide in the sliding groove 8 opened in the inner wall of the fixed rear plate 7, thereby improving the stability and smoothness of the installation process between the mounting base plate 4 and the fixed rear plate 7. After being installed at a suitable distance, the slot 6 will lock into the inside of the slot 9 to fix the position of the mounting base plate 4, preventing the mounting base plate 4 from falling out of the device and affecting the use of the device.

[0046] The supporting connecting plate 14 forms a rotating structure with the outer supporting plate 12 via the top connecting shaft 13. The supporting connecting plates 14 also form a rotating structure via the middle connecting shaft 15. Furthermore, the supporting connecting plate 14 forms a rotating structure with the rear fixed wheel 17 via the bottom connecting shaft 16. Finally, the supporting connecting plate 14 forms a rotating structure with the outer sleeve rod 20 via the bottom connecting shaft 16. After the front plate 1 and the fixed rear plate 7 are installed, the drive shaft 3 will enter the adjusting groove 21. During the translation of the outer sleeve rod 20 by the threaded rod 19, the middle connecting shaft 15 will connect with the outer sleeve rod via the front bottom connecting shaft 16. When the rod 20 rotates, it will also rotate through the bottom connecting shaft 16 and the rear fixed wheel 17. At this time, the distance between the bottom connecting shaft 16 and the outer rod 20 changes, which will change the height between the top of the middle shaft 15 and the outer rod 18. Since the outer support plate 12 is connected to the top of the middle shaft 15, the outer support plate 12 will rise and fall inside the device to adjust the distance between it and the outer rod 18. This makes it easy to adjust the overall diameter of the outer support plate 12, which can install and fix hot-dip galvanized steel strip coils of different sizes and facilitate the uncoiling of the steel strip.

[0047] The outer rod 20 forms a forward and backward translational structure with the threaded rod 19 and the outer rod 18. The drive shaft 3 forms a detachable structure with the threaded rod 19 through the adjustment groove 21. The dimensions of the drive shaft 3 and the adjustment groove 21 are matched. After the front plate 1 and the fixed rear plate 7 are installed, the drive shaft 3 will enter the interior of the adjustment groove 21. Since the dimensions of the drive shaft 3 and the adjustment groove 21 are matched, when the drive shaft 3 is driven to rotate by the drive component 2, it will drive the threaded rod 19 behind the adjustment groove 21 to rotate. When the threaded rod 19 rotates, the externally engaged adjustment groove 21 will translate outside the threaded rod 19. When the outer rod 20 translates, it will change the distance between itself and the rear fixed wheel 17, thereby adjusting the distance between the outer support plate 12 and the outer rod 18, which facilitates the adjustment of the overall diameter of the device.

[0048] Example 3

[0049] This embodiment is based on the previous embodiment, but differs from the previous embodiment in that it provides a feeding component for the automatic cutting device of hot-dip galvanized steel strip.

[0050] The pointed blocks 24 are arrayed inside the side plate 22. The bottom of the cleaning brush 26 is at the same horizontal level as the top of the pointed blocks 24. The cleaning brush 26 is rotatably connected to the central mounting base 25. During use, the user places the steel strip on the top of the pointed blocks 24. This ensures support for the steel strip while preventing the steel strip from sticking to the plane due to insufficient gap between the steel strip and the support plane, which would affect the use of the device. It also prevents the steel strip from being fixed to the support plane due to high temperature during the cutting process, which would affect its use. At the same time, the cleaning brush 26 installed on the top of the pointed blocks 24 can also clean the steel strip that enters the device to be cut, so as to prevent dirt or other impurities from affecting the cutting quality.

[0051] The upper drive wheel 31 forms a rotating structure through the engagement of the lower driven gear 29 and the upper drive gear 28. The lower driven gear 29 and the upper drive gear 28 are perpendicular to each other. The transmission shaft 30 is fixed to the lower driven gear 29. The rear drive gear 32 forms a rotating structure through the transmission shaft 30. The lower drive wheel 34 forms a rotating structure through the engagement of the rear driven gear 33 and the rear drive gear 32. During use, the top drive motor 27 drives the upper drive gear 28 to rotate, and then the upper drive gear 28 drives the lower driven gear 29 to rotate. Since the lower driven gear 29 is fixed to the transmission shaft 30, the transmission shaft 30 also rotates inside the device. When the drive shaft 30 rotates, it drives the upper drive wheel 31 to rotate. Since the rear drive gear 32 is installed behind the drive shaft 30, the rear drive gear 32 will rotate in the same direction as the drive shaft 30. At the same time, the rear driven gear 33 meshes with the rear drive gear 32, so the rear driven gear 33 will rotate in the opposite direction to the rear drive gear 32. The rear driven gear 33 then drives the lower drive wheel 34 to rotate. The rotation direction of the lower drive wheel 34 is the same as that of the rear driven gear 33, but opposite to the rotation direction of the upper drive wheel 31. This allows the steel belt that enters the position between the upper drive wheel 31 and the lower drive wheel 34 to be pushed forward, facilitating the feeding of materials by the device.

[0052] Example 4

[0053] This embodiment is based on the previous embodiment, but differs from the previous embodiment in that it provides a cutting component for an automatic hot-dip galvanized steel strip cutting device.

[0054] The suction cup 38 forms a lifting structure via the hydraulic rod 37. The hydraulic rod 37 forms a rotating structure with the front mounting plate 35 via the top rotating shaft 36. The hydraulic rod 37 forms a pressing structure with the front mounting plate 35 via the return spring 39. After the device completes the cutting of the steel strip, the cut part and the uncut part form a break. At this time, the suction cup 38 moves downward under the drive of the hydraulic rod 37 and then adsorbs the steel strip. After being sucked in, the break of the steel strip is lifted. Then, the upper drive wheel 31 and the lower drive wheel 34 at the rear rotate to feed the material. At this time, the suction cup 38 will rotate under the action of the top hydraulic rod 37. At this time, the return spring 39 will be stretched, and the uncut head will be placed above the cut steel strip. Then the suction cup 38 is lowered, and the hydraulic rod 37 returns to its original position under the elastic action of the return spring 39 for the next use.

[0055] The upper drive gear 41 forms a rotating structure through the cooperation between the bottom drive gear 42 and the front drive motor 43. The moving wheel 40 forms a rotating structure through the upper drive gear 41. The front mounting plate 35 forms a translational structure with the side plate 22 through the cooperation between the moving wheel 40 and the side moving groove 50. The front drive motor 43 drives the bottom drive gear 42 to rotate inside the device. Then, the bottom drive gear 42 drives the upper drive gear 41 meshing on both sides to rotate. At the same time, the two upper drive gears 41 rotate in the same direction. Since the moving wheel 40 is installed behind the upper drive gear 41, the moving wheel 40 also rotates inside the device. Therefore, the moving wheel 40 will translate inside the side moving groove 50, which facilitates the adjustment of the left and right position of the front mounting plate 35 inside the device and the adjustment of the position for cutting the steel strip.

[0056] The laser cutting head 47 forms a translation structure with the mounting groove 44 through the cooperation between the moving gear 46 and the rack 45. The width of the mounting groove 44 is equal to the width between the side plates 22. During use, the stepper motor 49 drives the moving gear 46 to rotate inside the device. Since the moving gear 46 and the rack 45 mesh with each other, the moving gear 46 will translate outside the rack 45, which can adjust the left and right position of the laser cutting head 47 connected at the bottom inside the device, making it convenient to cut the steel strip.

[0057] Example 5

[0058] This embodiment is based on the previous embodiment, but differs from the previous embodiment in that it provides a method for an automatic cutting device for hot-dip galvanized steel strip.

[0059] The steel strip coil is placed outside the outer support plate 12, and then the front plate 1 is installed in front of the fixed rear plate 7. At this time, as the threaded rod 19 drives the outer sleeve rod 20 to move horizontally, the drive shaft 3 will enter the interior of the adjustment groove 21. Since the dimensions of the drive shaft 3 and the adjustment groove 21 match, when the drive shaft 3 is driven to rotate by the drive component 2, it will drive the threaded rod 19 behind the adjustment groove 21 to rotate. When the threaded rod 19 rotates, the externally engaged adjustment groove 21 will move horizontally outside the threaded rod 19. When the outer sleeve rod 20 moves horizontally, it will change the distance between itself and the rear fixed wheel 17. The middle rotating shaft 15 will rotate with the outer sleeve rod 20 through the front bottom connecting rotating shaft 16, and at the same time, it will rotate with the rear fixed wheel 17 through the rear bottom connecting rotating shaft 16. When the device moves, the distance between the bottom connecting shaft 16 and the outer rod 20 changes, thus changing the height between the top of the middle shaft 15 and the outer rod 18. Since the outer support plate 12 is connected to the top of the middle shaft 15, the outer support plate 12 will rise and fall inside the device to adjust the distance between itself and the outer rod 18. This facilitates adjustment of the overall diameter of the outer support plate 12, enabling the installation and fixing of hot-dip galvanized steel strip coils of different sizes. It also facilitates the fixing and uncoiling of the steel strip. Afterward, the steel strip is guided into the left side of the device through the top connecting shaft 13. The top drive motor 27 drives the upper drive gear 28 to rotate, and then the upper drive gear 28 drives the lower driven gear 29 to rotate. Since the lower driven gear 29 is fixed to the transmission shaft 30, therefore... The drive shaft 30 also rotates inside the device. When the drive shaft 30 rotates, it drives the upper drive wheel 31 to rotate. Since a rear drive gear 32 is installed behind the drive shaft 30, the rear drive gear 32 rotates in the same direction as the drive shaft 30. Simultaneously, the rear driven gear 33 meshes with the rear drive gear 32, causing the rear driven gear 33 to rotate in the opposite direction to the rear drive gear 32. The rear driven gear 33 then drives the lower drive wheel 34 to rotate. The lower drive wheel 34 rotates in the same direction as the rear driven gear 33, but in the opposite direction to the upper drive wheel 31. This propels the steel belt between the upper drive wheel 31 and the lower drive wheel 34 forward, facilitating feeding. The steel belt then enters... Once inserted into the bottom of the front mounting plate 35, the stepper motor 49 drives the moving gear 46 to rotate inside the device. Since the moving gear 46 meshes with the rack 45, it translates outside the rack 45, adjusting the left-right position of the bottom-connected laser cutting head 47 within the device for easier cutting of the steel strip. After one cut, a break is formed between the cut and uncut portions. At this point, the suction cup 38 moves downwards under the drive of the hydraulic rod 37, adsorbing the steel strip and lifting the break. The upper drive wheel 31 and lower drive wheel 34 at the rear then rotate to feed the strip. Meanwhile, the suction cup 38 rotates under the action of the top hydraulic rod 37.At this point, the return spring 39 will be stretched, placing the uncut head above the cut steel strip. The suction cup 38 will then be lowered, and the hydraulic rod 37 will return to its original position under the elastic action of the return spring 39, ready for the next use.

[0060] Working principle: First, the steel strip coil is placed outside the outer support plate 12. Then, the front plate 1 is installed in front of the fixed rear plate 7. At this time, as the threaded rod 19 drives the outer sleeve rod 20 to move horizontally, the drive shaft 3 enters the interior of the adjustment groove 21. Since the dimensions of the drive shaft 3 and the adjustment groove 21 match, when the drive shaft 3 is driven to rotate by the drive component 2, it will drive the threaded rod 19 behind the adjustment groove 21 to rotate. When the threaded rod 19 rotates, the externally engaged adjustment groove 21 will move horizontally outside the threaded rod 19. The outer sleeve rod 20 will change during the horizontal movement. The distance between the central pivot 15 and the rear fixed wheel 17 is adjusted. The central pivot 15 rotates via the front bottom connecting pivot 16 and the outer rod 20, and simultaneously rotates via the rear bottom connecting pivot 16 and the rear fixed wheel 17. This change in the distance between the bottom connecting pivot 16 and the outer rod 20 alters the height between the top of the central pivot 15 and the outer rod 18. Since the outer support plate 12 is connected to the top of the central pivot 15, it can rise and fall within the device, adjusting the distance between itself and the outer rod 18 for easy adjustment. The overall diameter allows for the installation and fixing of hot-dip galvanized steel strip coils of different sizes, facilitating the fixing and uncoiling of the steel strip. The steel strip is then guided into the left side of the device via the top connecting shaft 13. The top drive motor 27 drives the upper drive gear 28 to rotate, which in turn drives the lower driven gear 29. Since the lower driven gear 29 is fixed to the drive shaft 30, the drive shaft 30 also rotates inside the device. When the drive shaft 30 rotates, it drives the upper drive wheel 31 to rotate. Because the drive shaft 30 is mounted at the rear... With a rear drive gear 32, the rear drive gear 32 will rotate in the same direction as the drive shaft 30. At the same time, the rear driven gear 33 meshes with the rear drive gear 32, so the rear driven gear 33 will rotate in the opposite direction to the rear drive gear 32. The rear driven gear 33 will then drive the lower drive wheel 34 to rotate. The lower drive wheel 34 rotates in the same direction as the rear driven gear 33, but in the opposite direction to the upper drive wheel 31. This will push the steel belt that enters between the upper drive wheel 31 and the lower drive wheel 34 forward, making it convenient for the device to feed materials.

[0061] Then the steel strip enters the bottom of the front mounting plate 35. The stepper motor 49 drives the moving gear 46 to rotate inside the device. Since the moving gear 46 meshes with the rack 45, the moving gear 46 will translate outside the rack 45, which can adjust the left and right position of the laser cutting head 47 connected at the bottom inside the device, making it convenient to cut the steel strip. After the steel strip is cut once, the cut part and the uncut part form a break. At this time, the suction cup 38 moves downward under the drive of the hydraulic rod 37, and then the suction cup 38 adsorbs the steel strip. After being sucked in, the break of the steel strip is lifted, and then the upper drive wheel 31 and the lower drive wheel 34 at the rear rotate to feed the material. At this time, the suction cup 38 will rotate under the action of the top hydraulic rod 37, which will stretch the return spring 39, placing the uncut head on top of the cut steel strip. Then the suction cup 38 is lowered, and the hydraulic rod 37 returns to its original position under the elastic action of the return spring 39 for the next use.
