Description

Technical Field

[0001] This utility model relates to the field of aluminum sheet and strip technology, and specifically to an automatic aluminum sheet and strip slitting device. Background Technology

[0002] Aluminum sheet and strip refer to aluminum sheets or strips made primarily from aluminum and mixed with other alloying elements. Aluminum sheet and strip are important basic materials for the development of my country's national economy. Aluminum sheet and strip are cut from aluminum sheets and then spun into coils by aluminum sheet and strip slitting devices before being put into practical applications. The quality of aluminum sheet and strip slitting determines the quality and performance of the aluminum sheet and strip products.

[0003] An automatic aluminum strip slitting device, as described in application number CN202021393351.0 and authorized announcement date 20210615, includes a base, a second rotating shaft, and slitting wheels. A first rotating shaft is connected between the base components. A second rotating shaft is positioned above the first rotating shaft. A third rotating shaft is positioned to one side of the second rotating shaft. A fourth rotating shaft is positioned below the third rotating shaft. Slitting wheels are positioned on the outer sides of the first, second, third, and fourth rotating shafts. Support columns are positioned below the base, and partitions are positioned between the support columns. A motor is positioned above the partitions. The advantages are: by incorporating a motor, first, second, third, and fourth rotating shafts, and slitting wheels, this device can automatically slit aluminum strips, avoiding the low slitting efficiency caused by slow manual operation and improving the overall efficiency of the aluminum strip slitting device.

[0004] In aluminum sheet and strip slitting machines, the slitting cutters are mostly fixed with bolts. When it is necessary to adjust the distance between each slitting cutter, the adjustment is difficult, which makes it impossible to quickly adjust the slitting cutters during slitting and affects the processing efficiency of the slitting machine. Therefore, it is urgent to design an automatic aluminum sheet and strip slitting device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic aluminum strip slitting device to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic aluminum sheet and strip slitting device includes a frame assembly. The frame assembly includes a frame, and a slitting component is disposed inside the frame. The slitting component includes two mounting cylinders, which are mounted inside the frame via bearings. A piston block is slidably connected inside each mounting cylinder. An adjusting screw is mounted on one end of each mounting cylinder via a bearing, and the adjusting screw extends into the interior of the mounting cylinder. The adjusting screw and the piston block are threadedly connected. A transmission gear is mounted on one end of each mounting cylinder via a key, and the two transmission gears mesh with each other. Five cutting blades are disposed on the outside of each mounting cylinder, one of which is a cutting blade. The cutting blade is bolted to the outside of the mounting cylinder. Four other cutting blades are slidably connected to the outside of the mounting cylinder. Three cylinders are provided on one side of the outer wall of each cutting blade, and a cylinder rod is slidably inserted into one end of each cylinder. One end of the cylinder rod is set on an adjacent cutting blade. The mounting cylinder is connected to the cylinders through a pipe. Each cutting blade includes a mounting plate. Three threaded holes are opened on both sides of the outer wall of the mounting plate. One end of each cylinder and cylinder rod is threaded into the threaded holes. Cutters are snapped into both sides of the mounting plate. Three fixing bolts are inserted into one side of the outer wall of the mounting plate, and one end of each fixing bolt passes through the cutting blade.

[0008] Furthermore, multiple guide rollers are installed inside the box frame via bearings, and a housing is installed on one side of the outer wall of the box frame via bolts, with the transmission gear located inside the housing.

[0009] Furthermore, a drive motor is bolted to one side of the outer wall of the housing, and the output end of the drive motor is fixedly connected to one of the mounting cylinders via a flat key.

[0010] Furthermore, the box frame assembly is provided with two leveling components on the outside. The leveling components include mounting brackets. The mounting brackets have placement grooves on both outer walls, and a telescopic cylinder is installed on one side of the inner wall of the placement groove by bolts.

[0011] Furthermore, two sliding rods are bolted inside the mounting groove, and a slider is slidably connected between the two sliding rods. The slider is fixedly connected to the output end of the telescopic cylinder by bolts, and a guide roller is installed between the two sliders by bearings.

[0012] Furthermore, the mounting frame has a storage area inside, and both the storage area and the mounting cylinder are filled with hydraulic oil. The storage area is connected to the telescopic cylinder through a pipe. A piston plate is slidably connected inside the storage area. An adjusting screw is installed at the center of the outer wall on one side of the top of the mounting frame through a bearing, and the adjusting screw is threadedly connected to the piston plate.

[0013] Furthermore, the box frame assembly is provided with an anti-displacement component, which includes a mounting shell. Two fixing plates are installed inside the mounting shell by bolts, and a lead screw is installed between one side of the outer wall of the fixing plate and one side of the inner wall of the mounting shell through a bearing. A sliding plate is externally threaded to the lead screw and is slidably connected inside the mounting shell. A roller is installed on one side of the outer wall of the sliding plate through a bearing.

[0014] Furthermore, an adjusting rod is mounted on one side of the outer wall of the mounting housing via a bearing, and a bevel gear two is mounted on one end of the adjusting rod via a flat key. A bevel gear one is mounted on one end of the lead screw via a flat key, and bevel gear one and bevel gear two mesh with each other.

[0015] In the above technical solution, the automatic aluminum strip slitting device provided by this utility model has the following advantages:

[0016] (1) When it is necessary to cut aluminum strips of different widths by using the set slitting assembly, the adjusting screw can be turned with a tool. The adjusting screw will slide the piston block inside the mounting cylinder. The sliding piston block will squeeze the hydraulic oil inside the mounting cylinder. Then the hydraulic oil will flow into the cylinder through the pipe and apply force to the cylinder rod inside the cylinder. The structure formed by the cylinder rod and the cylinder will unfold, so that the distance between multiple cutting blades changes synchronously. The above steps can be repeated to complete the adjustment of the cutting blade on another mounting cylinder. Moreover, the adjustment is relatively easy and the slitting blade structure can be quickly adjusted.

[0017] (2) When the aluminum strip is introduced into the box frame assembly for slitting by the anti-deviation component, the adjusting rod can be rotated. Then the adjusting rod will drive the second bevel gear to rotate. The rotating second bevel gear will drive the two first bevel gears to rotate. The first bevel gear will drive the lead screw to rotate. The lead screw will drive the sliding plate to slide inside the mounting shell, so that the two rollers move towards each other, so as to restrict the two sides of the aluminum strip to be slitting and avoid the aluminum strip deviation problem during unwinding.

[0018] (3) The aluminum strip is introduced into the device during the slitting process through the leveling component and guide roller one. The adjusting screw can be operated to rotate, and then the adjusting screw will slide the piston plate inside the storage area. The sliding piston plate will squeeze the hydraulic oil inside the storage area. The hydraulic oil will flow into the two telescopic cylinders through the pipe. Then the telescopic cylinders will unfold, so that the guide roller two position will drop close to the guide roller one, and work with the guide roller one to squeeze the aluminum strip. Subsequently, as the aluminum strip is wound up and unwound, the structure formed by the guide roller one and the guide roller two can level the aluminum strip, so as to avoid the wrinkles of the aluminum strip affecting the slitting component during slitting. At the same time, it can also prevent wrinkles from appearing on the cut of the slitting aluminum strip. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-8 As shown in the figure, an automatic aluminum strip slitting device provided by this utility model includes a frame assembly 1, which includes a frame 4. A slitting assembly 8 is provided inside the frame 4. The slitting assembly 8 includes two mounting cylinders 9, which are mounted inside the frame 4 via bearings. A piston block 13 is slidably connected inside the mounting cylinder 9. An adjusting screw 12 is mounted on one end of the mounting cylinder 9 via a bearing, and the adjusting screw 12 extends into the mounting cylinder 9. The adjusting screw 12 and the piston block 13 are threadedly connected. A transmission gear 10 is mounted on one end of the mounting cylinder 9 via a flat key, and the two transmission gears 10 mesh with each other. Five cutting blades 11 are provided on the outside of the mounting cylinder 9, one of which is a cutting blade... Component 11 is bolted to the outside of the mounting cylinder 9. Four other cutting components 11 are slidably connected to the outside of the mounting cylinder 9. Three cylinders 14 are provided on one side of the outer wall of the cutting component 11, and a cylinder rod 15 is slidably inserted into one end of the cylinder 14. One end of the cylinder rod 15 is set on the adjacent cutting component 11. The mounting cylinder 9 is connected to the cylinder 14 through a pipe. The cutting component 11 includes a mounting plate 17. Three threaded holes 16 are opened on both sides of the outer wall of the mounting plate 17. One end of the cylinder 14 and the cylinder rod 15 is threaded into the threaded hole 16. Cutters 18 are snapped into both sides of the mounting plate 17. Three fixing bolts 19 are inserted into one side of the outer wall of the mounting plate 17, and one end of the fixing bolts 19 passes through the cutter 18.

[0032] Specifically, in this embodiment, a box frame assembly 1 is included, which includes a box frame 4. A winding assembly 8 is provided inside the box frame 4. The winding assembly 8 includes two mounting cylinders 9, which are mounted inside the box frame 4 via bearings. A piston block 13 is slidably connected inside the mounting cylinder 9. An adjusting screw 12 is mounted on one end of the mounting cylinder 9 via a bearing. Rotating the adjusting screw 12 causes the piston block 13 to slide inside the mounting cylinder 9. The sliding piston block 13 compresses the hydraulic oil inside the mounting cylinder 9, and then the hydraulic oil flows into a cylinder 14 through a pipe, applying force to the cylinder rod 15 inside the cylinder 14. This allows the structure formed by the cylinder rod 15 and cylinder barrel 14 to unfold, and the adjusting screw 12 extends into the mounting cylinder 9. The adjusting screw 12 and the piston block 13 are connected by a thread. One end of the mounting cylinder 9 is equipped with a transmission gear 10 via a flat key. The transmission between the two transmission gears 10 facilitates the synchronous rotation between the two mounting cylinders 9, and the two transmission gears 10 mesh with each other. Five cutting blades 11 are provided on the outside of the mounting cylinder 9. The middle cutting blade 11 is fixed to the mounting cylinder 9 by bolts, and one of the cutting blades 11 is bolted to the outside of the mounting cylinder 9. The other four... Each cutting blade 11 is slidably connected to the outside of the mounting cylinder 9. Three cylinders 14 are provided on one side of the outer wall of each cutting blade 11, and a cylinder rod 15 is slidably inserted into one end of each cylinder 14. The cylinder rod 15 and the cylinder 14 can form a telescopic hydraulic cylinder structure. When the structure formed by the cylinder rod 15 and the cylinder 14 is extended or retracted, the distance between the multiple cutting blades 11 can be changed. One end of the cylinder rod 15 is set on an adjacent cutting blade 11. The mounting cylinder 9 is connected to the cylinder 14 via a pipe. Each cutting blade 11 includes a mounting plate 17, and three threaded holes 16 are provided on both sides of the outer wall of the mounting plate 17. The threaded holes 16 facilitate... The cylinder barrel 14 and cylinder rod 15 are mounted on the mounting plate 17. One end of the cylinder barrel 14 and cylinder rod 15 is threaded into the threaded hole 16. Both sides of the mounting plate 17 are clamped with cutters 18. As the mounting cylinder 9 rotates, the cutters 18 can separate the aluminum strip that is being wound up and unwound. Three fixing bolts 19 are inserted into the outer wall of one side of the mounting plate 17, and one end of the fixing bolts 19 passes through the cutter 18. The cutter 18 is semi-circular. When it is necessary to remove the cutter 18, the fixing bolts 19 can be unscrewed to release the restriction between the cutter 18 and the mounting plate 17, so that workers can quickly remove the cutter 18 and replace it with a new one.

[0033] This utility model provides an automatic aluminum sheet and strip slitting device. By rotating the adjusting screw 12 with a tool, the adjusting screw 12 will slide the piston block 13 inside the mounting cylinder 9. The sliding piston block 13 will squeeze the hydraulic oil inside the mounting cylinder 9, and then the hydraulic oil will flow into the cylinder 14 through the pipe, applying force to the cylinder rod 15 inside the cylinder 14. The structure formed by the cylinder rod 15 and the cylinder 14 will unfold, so that the distance between multiple cutting blades 11 changes synchronously. The above steps can be repeated to complete the adjustment of the cutting blades 11 on another mounting cylinder 9. Moreover, the adjustment is relatively easy and can achieve rapid adjustment of the slitting blade structure.

[0034] In one embodiment provided by this utility model, such as Figure 2 As shown, multiple guide rollers 5 are installed inside the frame 4 via bearings. A housing 6 is bolted to one side of the outer wall of the frame 4. A transmission gear 10 is located inside the housing 6. A drive motor 7 is bolted to one side of the outer wall of the housing 6. The preferred model of the drive motor 7 is 57BL06. When the drive motor 7 moves, one of the mounting cylinders 9 will rotate with the cutting blade 11. At the same time, under the transmission action of the two transmission gears 10, the two mounting cylinders 9 will rotate simultaneously. The two sets of cutting blades 11 can realize the cutting of aluminum strip. The output end of the drive motor 7 is fixedly connected to one of the mounting cylinders 9 via a flat key.

[0035] In another embodiment provided by this utility model, such as Figure 1 and Figure 8As shown, the frame assembly 1 has two leveling components 2 on its exterior. Each leveling component 2 includes a mounting frame 20. The outer walls of both sides of the mounting frame 20 have mounting grooves 24. A telescopic cylinder 25 is bolted to one side of the top of the inner wall of each mounting groove 24. The preferred model of the telescopic cylinder 25 is MOB30*50. Two sliding rods 26 are bolted inside the mounting grooves 24. The sliding rods 26 guide the movement of the slider 27, and a slider 27 is slidably connected between the two sliding rods 26. The slider 27 is fixedly connected to the output end of the telescopic cylinder 25 by bolts. A second guide roller 28 is mounted between the two sliders 27 via a bearing. The second guide roller 28, in conjunction with the first guide roller 5, can extrude the aluminum strip. The mounting frame 20 has a storage area 22 inside. The storage area 22 and the mounting frame 20... The cylinder 9 is filled with hydraulic oil. The storage area 22 is connected to the telescopic cylinder 25 through a pipe. A piston plate 23 is slidably connected inside the storage area 22. An adjusting screw 21 is installed at the center of the outer wall on one side of the top of the mounting frame 20 through a bearing. When the adjusting screw 21 is rotated, it will slide the piston plate 23 inside the storage area 22. The sliding piston plate 23 will squeeze the hydraulic oil inside the storage area 22. The hydraulic oil will flow into the two telescopic cylinders 25 through the pipe. Then the telescopic cylinders 25 will unfold, causing the guide roller 28 to descend and approach the guide roller 5. The guide roller 5 will then squeeze the aluminum strip. With the movement of the aluminum strip, the flattening of the aluminum strip is achieved. The adjusting screw 21 and the piston plate 23 are threadedly connected.

[0036] In another embodiment provided by this utility model, such as Figure 1 and 7 As shown, the frame assembly 1 has an anti-displacement component 3 inside. The anti-displacement component 3 includes a mounting shell 29. Two fixing plates 30 are bolted to the inside of the mounting shell 29. A lead screw 36 is mounted between one outer wall of the fixing plate 30 and one inner wall of the mounting shell 29 via a bearing. A sliding plate 31 is threaded to the outside of the lead screw 36. When the lead screw 36 rotates, the sliding plate 31 slides inside the mounting shell 29 and is slidably connected inside the mounting shell 29. A roller 32 is mounted to one outer wall of the sliding plate 31 via a bearing, and an adjusting rod 34 is mounted to one outer wall of the mounting shell 29 via a bearing. One end of the lever 34 is fitted with a bevel gear 35 via a flat key. Rotating the adjusting lever 34 causes the bevel gear 35 to rotate. One end of the lead screw 36 is fitted with a bevel gear 33 via a flat key. The rotating bevel gear 35 drives the two bevel gears 33 to rotate, which in turn drives the lead screw 36 to rotate. The lead screw 36 then slides the sliding plate 31 inside the mounting housing 29, causing the two rollers 32 to move towards each other. This helps to restrict the two sides of the aluminum strip to be slit, preventing the aluminum strip from shifting during unwinding. The bevel gears 33 and 35 mesh with each other.

[0037] Working principle: When the aluminum strip is introduced into the frame assembly 1 for slitting, the adjusting screw 21 can be rotated first. The adjusting screw 21 then slides the piston plate 23 inside the storage area 22. The sliding piston plate 23 squeezes the hydraulic oil inside the storage area 22. The hydraulic oil flows into the two telescopic cylinders 25 through pipes. The telescopic cylinders 25 then expand, causing the guide roller 28 to descend and approach the guide roller 5, thus squeezing the aluminum strip. Next, the adjusting rod 34 can be rotated, which drives the bevel gear 25 to rotate. The rotating bevel gear 25 drives the two bevel gears 33 to rotate, which in turn drives the screw 36 to rotate. The screw 36 then slides the sliding plate 31 inside the mounting housing 29, causing the two rollers 32 to move towards each other, facilitating the sliding of the aluminum strip. Side-mounted restrictions prevent aluminum strip misalignment during unwinding. During slitting, as the aluminum strip is unwound and rewound, the cutters 18 on the two sets of cutters 11 slit the strip. The slit strip moves out of the housing 4 as it is rewound. During slitting, the adjusting screw 12 can be rotated, causing the piston block 13 to slide inside the mounting cylinder 9. The sliding piston block 13 compresses the hydraulic oil inside the mounting cylinder 9, which then flows through a pipe into the cylinder 14, applying force to the cylinder rod 15 inside. The structure formed by the cylinder rod 15 and the cylinder 14 unfolds, causing the distance between the multiple cutters 11 to change synchronously. Repeating these steps allows adjustment of the cutter 11 on another mounting cylinder 9, meeting the requirements of the slitting assembly 8 to slit aluminum strips of different widths.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
