Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum foil coil processing, and particularly relates to a cutting device for aluminum foil coil processing. Background Technique

[0002] Aluminum foil is a hot stamping material directly rolled from metal aluminum into thin sheets. Its hot stamping effect is similar to that of pure silver foil stamping, so it is also called false silver foil. Due to the soft texture and good ductility of aluminum, it has a silver-white luster. Aluminum foil is widely used in food, beverages, cigarettes, pharmaceuticals, photographic plates, household daily necessities, etc.

[0003] During the cutting process of aluminum foil coils, sometimes it is necessary to cut the aluminum foil coils into strips, that is, to cut the aluminum foil in the mother roll into long strips that meet the width requirements. The existing aluminum foil coil cutting devices cannot quickly adjust the spacing between each cutting knife during cutting, and the adjustment range is small, and the operation is cumbersome. Content of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present utility model is to provide a cutting device for aluminum foil coil processing, which effectively solves the problem that the spacing between each cutting knife is not easy to adjust.

[0005] The technical solution for solving its technical problems is: it includes a workbench, an aluminum foil coil is conveyed on the workbench, a frame is arranged on the right side of the workbench, a frame body is arranged above the frame, a first rotating shaft and a second rotating shaft arranged in the front-back direction are rotatably connected to the frame body, the second rotating shaft is located on the left side of the first rotating shaft, a driving roller in contact with the upper surface of the aluminum foil coil is coaxially fixed to the second rotating shaft, and a transmission component is arranged between the first rotating shaft and the second rotating shaft;

[0006] A spline shaft is coaxially fixed to the first rotating shaft, a plurality of cutting discs are spline-connected to the spline shaft, a limiting block corresponding to the cutting disc is slidably connected in the front-back direction in the frame body, a fixed shaft located on both the front and back sides of the cutting disc is fixed to the lower end of the limiting block, the fixed shaft is arranged in the vertical direction, a roller is rotatably connected to the fixed shaft, the roller is in rolling connection with the surface of the cutting disc, a screw rod is fixed to the upper end of the limiting block, and a nut located outside the frame body is threadedly connected to the screw rod.

[0007] Preferably, a motor is fixed to the frame body, and the motor is coaxially fixedly connected to the first rotating shaft.

[0008] Preferably, the upper end of the cutting disc is located inside the limiting block, and the limiting block is not in contact with the cutting disc.

[0009] Preferably, a scale line is arranged on the upper surface of the frame body.

[0010] Preferably, sliders are fixed to both the left and right ends of the screw rod, and a sliding groove in the front-back direction is arranged in the frame body, and the sliders slide in the front-back direction in the sliding groove.

[0011] Preferably, the transmission assembly includes a first pulley coaxially and fixedly connected to a first rotating shaft, a second pulley coaxially fixed to a second rotating shaft, and the first pulley and the second pulley are connected by a belt.

[0012] The utility model has the following advantages compared with traditional equipment: 1) Good linkage. The spline shaft and the transmission roller are linked together through a belt, with a clever structure and low cost. The transmission roller can not only position the aluminum foil coil, but also drive the aluminum foil coil to move towards the cutting disc, which is convenient and practical; 2) Adopting a spline structure, each cutting disc can not only rotate and cut synchronously with the spline shaft, but also slide back and forth on the spline shaft to quickly adjust the distance between each cutting disc to meet the requirements of aluminum foil slitting with different widths, and has a wide range of applications; 3) The limiting block and roller structure. The roller does not affect the rotation of the cutting disc, and can also limit the cutting disc. The rolling connection has a small friction force, which improves the stability of the cutting disc during the cutting process. The combination of the screw and the nut is convenient to loosen or tighten, and can adjust the positions of the limiting block and the cutting disc at any time, with simple operation, good flexibility and high working efficiency.

Detailed Description of the Invention

[0019] The following further describes in detail the specific embodiments of the utility model with reference to the accompanying drawings.

[0020] From Figures 1 to 5Provided is a cutting device for processing aluminum foil coils, including a workbench 1. An aluminum foil coil 2 is conveyed on the workbench 1. A frame 3 is provided on the right side of the workbench 1. Above the frame 3 is a frame body 4. The frame body 4 is rotatably connected with a first rotating shaft 5 and a second rotating shaft 6 arranged in the front-back direction. The second rotating shaft 6 is located on the left side of the first rotating shaft 5. A driving roller 7 in contact with the upper surface of the aluminum foil coil 2 is coaxially fixed to the second rotating shaft 6. A transmission assembly is provided between the first rotating shaft 5 and the second rotating shaft 6.

[0021] A spline shaft 8 is coaxially fixed to the first rotating shaft 5. The spline shaft 8 is spline-connected with a plurality of cutting discs 9. A limiting block 10 corresponding to the cutting discs 9 is slidably connected in the front-back direction in the frame body 4. A fixing shaft 11 located on both the front and back sides of the cutting disc 9 is fixed to the lower end of the limiting block 10. The fixing shaft 11 is arranged in the vertical direction. A roller 12 is rotatably connected to the fixing shaft 11. The roller 12 is in rolling connection with the surface of the cutting disc 9. A screw rod 13 is fixed to the upper end of the limiting block 10. A nut 14 located outside the frame body 4 is threadedly connected to the screw rod 13.

[0022] A motor 15 is fixed to the frame body 4. The motor 15 is coaxially fixedly connected to the first rotating shaft 5.

[0023] In order to prevent the limiting block 10 from interfering with the rotation of the cutting disc 9, the upper end of the cutting disc 9 is located inside the limiting block 10, and the limiting block 10 is not in contact with the cutting disc 9.

[0024] In order to observe the distances between the cutting discs 9, a scale line 16 is provided on the upper surface of the frame body 4.

[0025] In order to ensure the stability of the left-right sliding of the limiting block 10 in the frame body 4, sliding blocks 17 are fixed to both the left and right ends of the screw rod 13. A sliding groove 18 in the front-back direction is provided in the frame body 4. The sliding blocks 17 slide in the front-back direction in the sliding groove 18.

[0026] The transmission assembly includes a first pulley 19. The first pulley 19 is coaxially fixedly connected to the first rotating shaft 5. A second pulley 20 is coaxially fixed to the second rotating shaft 6. The first pulley 19 and the second pulley 20 are connected by a belt.

[0027] When the present utility model is in use, the aluminum foil coil 2 is conveyed from left to right on the workbench 1. A hydraulic cylinder is installed on the frame 3. The hydraulic cylinder controls the lifting movement of the frame body 4. The frame body 4 is lifted to an appropriate height so that the driving roller 7 can be in contact with the upper surface of the aluminum foil coil 2, and the cutting disc 9 can cut the aluminum foil coil 2 on the workbench 1. The motor 15 is started. The motor 15 drives the first rotating shaft 5 to rotate coaxially. The first rotating shaft 5 drives the spline shaft 8 and the first pulley 19 to rotate coaxially. The first pulley 19 drives the second pulley 20 through a belt. The second pulley 20 drives the second rotating shaft 6 to rotate coaxially. The second rotating shaft 6 drives the driving roller 7 to rotate coaxially. The driving roller 7 drives the aluminum foil coil 2 to move from left to right.

[0028] The spline shaft 8 drives multiple cutting discs 9 to rotate coaxially. The multiple cutting discs 9 can simultaneously cut the aluminum foil coil 2, with high cutting efficiency. The limiting block 10 is rotatably connected to rollers 12 located on the front and rear sides of the cutting disc 9. The rollers 12 are in rolling connection with the cutting disc 9. The rollers 12 neither affect the rotation and cutting of the cutting disc 9 nor can limit the cutting disc 9 in the front and rear directions, improving the stability of the cutting disc 9. When it is necessary to adjust the distance between each cutting disc 9, turn off the motor 15, loosen the nut 14, and the screw rod 13 drives the slider 17 to slide back and forth in the sliding groove 18. The screw rod 13 drives the limiting block 10, the rollers 12, and the cutting disc 9 to slide back and forth together. The cutting disc 9 slides back and forth along the spline shaft 8. The upper surface of the frame body 4 is provided with a scale line 16, and the distance between each cutting disc 9 can be adjusted arbitrarily, with flexible operation. After adjustment, tighten the nut 14. The structure is ingenious, with low cost and convenient to use.
