[0003]传统裁切装置中的送料机构依赖普通辊轴传动，因此铝箔易会因张力不均(波动±5N)出现横向偏移，导致裁切后成品宽度误差达±3mm，无法满足高精度包装(误差要求≤±0.5mm)，不符合产品生产规范
[0019] The aluminum foil can be cut with a cutting blade. During the process, the operator can turn the knob to move the U-shaped frame up and down via the screw. The U-shaped frame will then adjust the height of the guide rollers through the rotating rod to tighten the aluminum foil and prevent wrinkles from forming during movement. It can also adjust the tension of the aluminum foil to make it taut, which is beneficial for cutting the aluminum foil. In addition, the position of the two limit rings can be adjusted according to the width of the aluminum foil to prevent the aluminum foil from tilting or skewing during the transmission process, which would affect the cutting accuracy and cutting effect.

Abstract
Description
Technical Field
[0001] This application relates to the field of aluminum foil processing equipment technology, and more specifically, to an adjustable cutting device for aluminum foil production. Background Technology
[0002] Aluminum foil is widely used in industrial and civilian fields due to its lightness, thinness, and good ductility. In the final process of aluminum foil production, large rolls of aluminum foil need to be cut into finished rolls or sheets of specific widths (100-2000 mm) and lengths (500-5000 mm) according to downstream needs.
[0003] Traditional cutting devices rely on ordinary roller drives for feeding mechanisms. As a result, aluminum foil is prone to lateral shift due to uneven tension (fluctuation ±5N), leading to a finished product width error of ±3mm after cutting. This cannot meet the requirements for high-precision packaging (error requirement ≤ ±0.5mm) and does not comply with product manufacturing specifications.
[0004] To address the aforementioned problems, this application provides an adjustable cutting device for aluminum foil production. Utility Model Content
[0005] The adjustable cutting device for aluminum foil production provided in this application adopts the following technical solution:
[0006] An adjustable cutting device for aluminum foil production includes an upper frame and a lower frame, wherein an auxiliary mechanism is provided inside the upper frame and the lower frame, and the auxiliary mechanism extends to the outside of the upper frame and the lower frame.
[0007] The auxiliary mechanism includes two connecting blocks, both of which are fixedly embedded between the upper frame and the lower frame. A fixing plate is fixedly connected to the inner wall of one side of the lower frame. A screw is threaded into the fixing plate. A U-shaped frame is fitted at the top of the screw. A rotating rod is embedded inside the U-shaped frame. A guide roller is fixedly fitted to the outside of the rotating rod. Two limiting rings are fitted to the outside of the guide roller. The two limiting rings are symmetrically arranged about the center line of the guide roller. Two guide rods are fixedly connected to the bottom of the U-shaped frame. The bottom ends of the two guide rods penetrate the fixing plate and extend to the bottom of the fixing plate. A knob is fixedly connected to the bottom end of the screw. A through groove is opened on one side of the lower frame. A connecting component is provided on the outside of the through groove.
[0008] Furthermore, the connecting point between the rotating rod and the U-shaped frame is movably connected by a bearing, the connecting point between the U-shaped frame and the screw is movably connected by a bearing, and the inner walls of both limiting rings are made of anti-slip material.
[0009] With the above technical solution, since the inner walls of the two limiting rings are made of anti-slip material, the friction between the two limiting rings and the guide roller can be strengthened, and external forces can be avoided to prevent the two fiber rings from moving.
[0010] Furthermore, the connecting component includes two electric push rods, which are respectively fixedly connected to the inner walls of the upper frame and the lower frame, and each of the two electric push rods has a lifting plate fixedly connected to its bottom end.
[0011] By using the above technical solution and setting two electric push rods, it is easy to adjust the distance between multiple limit rollers in the later stage.
[0012] Furthermore, four spring telescopic rods are fixedly connected to the inner sides of both lifting plates, and four horizontal plates are fixedly connected to the inner ends of the multiple spring telescopic rods.
[0013] By using the above technical solution and setting a spring telescopic rod, a relatively gentle clamping force can be applied to the aluminum foil, thereby improving the stability of the aluminum foil during the transmission process.
[0014] Furthermore, multiple movable rods are movably embedded inside the four horizontal plates, and limit rollers are fixedly sleeved on the outer side of each of the multiple movable rods. Motors are fixedly connected to the front sides of the two front horizontal plates, and the output shafts of the two motors are respectively fixedly connected to two of the movable rods.
[0015] With the above technical solution, the two motors rotate in opposite directions, thus achieving the purpose of transporting aluminum foil.
[0016] Furthermore, an L-shaped rod is fixedly connected to one side of the bottom lifting plate, and a placement plate is fixedly connected to the top of the L-shaped rod. A cutting blade is provided on the top of the placement plate, and the cutting blade is fixedly connected to the upper frame through an electric push rod.
[0017] By using the above technical solution and setting an L-shaped rod, the placement plate can always be kept horizontal with the multiple limiting rollers located at the bottom.
[0018] In summary, this application includes the following beneficial technical effects:
[0019] The aluminum foil can be cut with a cutting blade. During the process, the operator can turn the knob to move the U-shaped frame up and down via the screw. The U-shaped frame will then adjust the height of the guide rollers through the rotating rod to tighten the aluminum foil and prevent wrinkles from forming during movement. It can also adjust the tension of the aluminum foil to make it taut, which is beneficial for cutting the aluminum foil. In addition, the position of the two limit rings can be adjusted according to the width of the aluminum foil to prevent the aluminum foil from tilting or skewing during the transmission process, which would affect the cutting accuracy and cutting effect.

[0029] Example:
[0030] This application discloses an adjustable cutting device for aluminum foil production. Please refer to [link to relevant documentation]. Figures 1 to 4 It includes an upper frame 1 and a lower frame 2. The upper frame 1 and the lower frame 2 are equipped with auxiliary mechanisms inside, and the auxiliary mechanisms extend to the outside of the upper frame 1 and the lower frame 2.
[0031] The auxiliary mechanism includes two connecting blocks 3, which are fixedly embedded between the upper frame 1 and the lower frame 2. A fixing plate 4 is fixedly connected to the inner wall of one side of the lower frame 2. A screw 5 is threaded into the fixing plate 4. A U-shaped frame 6 is fitted at the top of the screw 5. A rotating rod 7 is embedded inside the U-shaped frame 6. A guide roller 8 is fixedly fitted to the outside of the rotating rod 7. Two limiting rings 9 are fitted to the outside of the guide roller 8. The two limiting rings 9 are symmetrically arranged about the center line of the guide roller 8. Two guide rods 10 are fixedly connected to the bottom of the U-shaped frame 6. The bottom ends of the two guide rods 10 pass through the fixing plate 4 and extend to the bottom of the fixing plate 4. A knob 11 is fixedly connected to the bottom of the screw 5. A through groove is opened on one side of the lower frame 2. The rotating rod 7 and the U-shaped frame 6 are connected by a bearing. The U-shaped frame 6 and the screw 5 are connected by a bearing. The inner walls of the two limiting rings 9 are made of anti-slip material.
[0032] Please see Figure 2 The outside of the through groove is provided with a connecting component, which includes two electric push rods 12. The two electric push rods 12 are fixedly connected to the inner walls of the upper frame 1 and the lower frame 2 respectively. The bottom ends of the two electric push rods 12 are fixedly connected to lifting plates 14.
[0033] Please see Figure 2 and Figure 4 Four spring telescopic rods 15 are fixedly connected to the inner side of each of the two lifting plates 14. Four horizontal plates 16 are fixedly connected to the inner ends of the multiple spring telescopic rods 15. Multiple movable rods 17 are movably embedded inside the four horizontal plates 16. Limiting rollers 18 are fixedly sleeved on the outer side of the multiple movable rods 17. Motors 19 are fixedly connected to the front side of the two front horizontal plates 16. The output shafts of the two motors 19 are fixedly connected to two of the movable rods 17 respectively.
[0034] Please see Figure 2 An L-shaped rod 20 is fixedly connected to one side of the bottom lifting plate 14. A placement plate 21 is fixedly connected to the top of the L-shaped rod 20. A cutting blade 22 is provided on the top of the placement plate 21. The cutting blade 22 is fixedly connected to the upper frame 1 through an electric push rod 13.
[0035] The implementation principle of this embodiment is as follows: When in use, two electric push rods 12 can be started simultaneously, so that the telescopic ends of the two electric push rods 12 are in a stretched state. At this time, the two lifting plates 14 will drive the four horizontal plates 16 to move in opposite directions through multiple spring telescopic rods 15. When the distance between the multiple limiting rollers 18 is suitable for the aluminum foil, the power of the two electric push rods 12 can be turned off. Then, the two motors 19 are started. The output shafts of the two motors 19 drive two of the movable rods 17 to rotate in the opposite direction. The two movable rods 17 are made of anti-slip material, so they can drive the aluminum foil to move. At the same time, the multiple limiting rollers 18 can also apply a relatively gentle clamping force to the aluminum foil, further improving the stability of the aluminum foil during the transmission process.
[0036] While the aluminum foil moves, the electric push rod 13 intermittently drives the cutting blade 22 downward (this can be programmed and is a known technology, so it will not be described in detail here). The cutting blade 22 cuts the aluminum foil. During this time, the operator can turn the knob 11 to drive the U-shaped frame 6 to move up and down through the screw 5. The U-shaped frame 6 will then adjust the height of the guide roller 8 through the rotating rod 7 to tighten the aluminum foil and prevent wrinkles from forming during movement. It can also adjust the tension of the aluminum foil to make it taut, which is beneficial for cutting the aluminum foil. At the same time, the position of the two limiting rings 9 can be adjusted according to the width of the aluminum foil to prevent the aluminum foil from tilting or skewing during transmission, which would affect the cutting accuracy and cutting effect.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
