Description

Technical Field

[0001] This utility model relates to the technology of aluminum foil processing, and in particular to an aluminum foil cutting device. Background Technology

[0002] Aluminum foil, due to its excellent properties, is widely used in food, beverages, cigarettes, pharmaceuticals, photographic negatives, and household goods, typically as packaging material; it is also used as a material for electrolytic capacitors; as insulation material in buildings, vehicles, ships, and houses; and as decorative gold and silver thread, wallpaper, and decorative labels for various stationery printed materials and light industrial products. Among these various uses, packaging material is where aluminum foil's performance characteristics are most effectively utilized. Aluminum foil is a flexible metal film that not only possesses advantages such as moisture resistance, airtightness, light blocking, abrasion resistance, aroma retention, and non-toxicity and odorlessness, but also, due to its elegant silvery-white luster, is easy to process into beautiful patterns and designs of various colors, making it more appealing to consumers. In certain applications, aluminum foil needs to be cut into strips.

[0003] Existing aluminum foil cutting equipment cuts aluminum foil into multiple strips arranged sequentially using a cutter. Two take-up rollers then collect adjacent strips from different directions. Because the cut strips are close together, friction easily occurs between them during collection, especially since aluminum foil is relatively soft. This friction can deform or even damage the foil, affecting the overall cutting quality. Therefore, further improvements to existing aluminum foil cutting equipment are necessary. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide an aluminum foil cutting device that can effectively solve the problems of easy deformation, damage to aluminum foil, and impact on cutting quality when collecting strip aluminum foil cut by existing aluminum foil cutting devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aluminum foil cutting device includes a frame, a controller, a feeding roller, a tension roller, a cutting device, an adjusting roller, and a take-up roller. The controller is mounted on the frame. The feeding roller is rotatably mounted on the frame around its own axis. Multiple tension rollers are rotatably mounted on the frame around their own axes and are arranged in a staggered pattern. The cutting device is mounted on the frame and connected to the controller. Multiple tension rollers are positioned between the feeding roller and the input end of the output cutting device. The adjusting roller is rotatably mounted on the frame around its own axis and located beside the output end of the cutting device. Two take-up rollers are arranged in a front-to-back pattern, each rotatably mounted on the frame under the drive of an external driving mechanism. The two take-up rollers are located on the front and rear sides of the adjusting roller, respectively.

[0007] As a preferred embodiment, there are two feeding rollers, which are arranged vertically and alternately on the frame.

[0008] As a preferred embodiment, pressure sensors are provided at both ends of one of the tension wheels, and the pressure sensors are connected to the controller. A magnetic brake device is provided at one end of the feeding wheel, and the magnetic brake device is connected to the controller.

[0009] As a preferred embodiment, the frame is equipped with a tension adjustment device located beside the input end of the cutting device.

[0010] As a preferred embodiment, the tension adjustment device includes a rotating shaft and an auxiliary roller. The rotating shaft is rotatably mounted on the frame around its own axis. The auxiliary roller is adjustablely mounted on the frame and located beside the rotating shaft. The aluminum foil to be cut passes between the rotating shaft and the auxiliary roller and is pressed between the rotating shaft and the auxiliary roller.

[0011] As a preferred embodiment, the cutting device includes two cooperating cutting blade shafts, both of which are rotatably mounted on the frame and cooperate with each other, wherein one cutting blade shaft can be adjusted back and forth toward the other cutting blade shaft.

[0012] As a preferred embodiment, each take-up roller is installed and connected to the frame via an adjustment component, and the take-up roller is hinged to the frame via the corresponding adjustment component, allowing it to be adjusted back and forth on the frame.

[0013] As a preferred embodiment, the adjustment assembly includes a connecting shaft and a hinge rod. The connecting shaft is mounted on the frame, one end of the hinge rod is hinged to the connecting shaft, the take-up wheel is mounted on the other end of the hinge rod, and the external drive mechanism is mounted on the hinge rod and drives the take-up wheel to rotate back and forth.

[0014] As a preferred embodiment, a guide wheel is provided between the adjusting wheel and each of the two receiving wheels, and the guide wheel is mounted on the frame and can rotate back and forth around its own axis.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0016] The adjusting wheel is mounted on the frame and located next to the output end of the cutting device, allowing it to rotate back and forth around its own axis. Two take-up wheels are arranged in a front-to-back configuration, positioned on either side of the adjusting wheel. This design ensures that after the aluminum foil is cut by the cutting device, the distance between adjacent aluminum foils is increased first through the adjustment wheel's transmission, and then the two take-up wheels collect the foil from different directions. This prevents friction between adjacent aluminum foil strips due to excessive proximity, avoids deformation or damage to the foil, and guarantees the quality of the cutting process.

[0031] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a frame 10, a controller 20, a feeding wheel 30, a tension wheel 40, a cutting device 50, an adjusting wheel 60, and a receiving wheel 70.

[0032] The controller 20 is mounted on the frame 10. In this embodiment, a tension adjusting device 11 is mounted on the frame 10 and is located beside the input end of the cutting device 50. The tension adjusting device 11 includes a rotating shaft 111 and an auxiliary roller 112. The rotating shaft 111 is rotatably mounted on the frame 10 around its own axis. The auxiliary roller 112 is adjustable towards the rotating shaft 111 and is mounted on the frame 10 beside the rotating shaft 111. The aluminum foil to be cut passes between the rotating shaft 111 and the auxiliary roller 112 and is pressed between the rotating shaft 111 and the auxiliary roller 112, thereby ensuring the tension of the aluminum foil when it enters the cutting device 50 and preventing deformation of the aluminum foil during cutting.

[0033] The feeding roller 30 is rotatably mounted on the frame 10 around its own axis. The feeding roller 30 is used to feed aluminum foil raw materials. In this embodiment, there are two feeding rollers 30, arranged vertically and alternately on the frame 10, allowing two aluminum foils to be fed simultaneously. The tension roller 40 then bonds the two aluminum foils together, and they are cut together, effectively improving the efficiency of the cutting process. A magnetic brake device 31 is provided at one end of the feeding roller 30. The magnetic brake device 31 is connected to the controller 20. The magnetic brake device 31 is existing technology, so its specific structure will not be described in detail.

[0034] The tension rollers 40 are rotatably mounted on the frame 10 around their own axis. Multiple tension rollers 40 are arranged at staggered intervals. The aluminum foil is wound sequentially around these rollers, ensuring tension during the cutting process. In this embodiment, pressure sensors 41 are installed at both ends of one tension roller 40. These sensors are connected to the controller 20 and sense the pressure applied to the tension rollers 40 by the aluminum foil as it passes over them. In conjunction with the magnetic brake device 31, the resistance of the feeding roller 30 as it rotates is adjusted. When the pressure sensed by the pressure sensor 41 is too high, the magnetic brake device 31 adaptively reduces the resistance of the receiving roller 30 to ensure proper feeding of the aluminum foil. When the pressure sensed by the pressure sensor 41 is too low, the magnetic brake device 31 adaptively increases the resistance of the receiving roller 30 to maintain the tension of the aluminum foil on the tension rollers 40, ensuring the aluminum foil remains taut and guaranteeing the cutting effect.

[0035] The cutting device 50 is mounted on the frame 10 and connected to the controller 20; multiple tension wheels 40 are mounted between the feeding wheel 30 and the input end of the output cutting device 50; in this embodiment, the cutting device 50 includes two cooperating cutting blade shafts 51, both of which are rotatably mounted on the frame 10 and cooperate with each other, wherein one cutting blade shaft 51 can be adjusted back and forth toward the other cutting blade shaft 51, thereby adjusting the cutting depth according to the thickness of different aluminum foils to meet the cutting process of aluminum foils of different thicknesses.

[0036] The adjusting wheel 60 is rotatable around its own axis and is mounted on the frame 10 and located next to the output end of the cutting device 50.

[0037] The take-up rollers 70 are arranged in two rows, one in front of the other. Each take-up roller 70 is rotatably mounted on the frame 10 under the drive of an external drive mechanism. The two take-up rollers 70 are located on the front and rear sides of the adjusting roller 60, respectively. During take-up, the winding interval of adjacent cut strips of aluminum foil on the take-up rollers 70 is manually adjusted, and the spacing between adjacent strips of aluminum foil on the adjusting roller 60 is adjusted in conjunction with the setting of the adjusting roller 60, thereby preventing the spacing between adjacent aluminum foils from being too close during take-up. In this embodiment, each take-up roller 70 is installed and connected to the frame 10 through an adjusting component 71. The take-up roller 70 is hinged to the frame 10 and can be adjusted back and forth on the frame 10 through the corresponding adjusting component 71. The adjusting assembly 71 includes a connecting shaft 711 and a hinge rod 712. The connecting shaft 711 is mounted on the frame, and one end of the hinge rod 712 is hinged to the connecting shaft 711. The take-up wheel 70 is mounted on the other end of the hinge rod 712. The external drive mechanism is mounted on the hinge rod 712 and drives the take-up wheel 70 to rotate back and forth. A guide wheel 72 is provided between the adjusting wheel 60 and each of the two take-up wheels 70. The guide wheel 72 is rotatably mounted on the frame 10 around its own axis. By adjusting the take-up wheel 70 back and forth, the aluminum foil after take-up is always in contact with the guide wheel 71 during the take-up process, ensuring the flatness of the aluminum foil during take-up and preventing deformation.

[0038] The key design feature of this invention is that the adjusting wheel is rotatably mounted on the frame and located beside the output end of the cutting device. Two take-up wheels are arranged in a front-to-back configuration, one on each side of the adjusting wheel. This design ensures that after the aluminum foil is cut by the cutting device, the distance between adjacent aluminum foils is increased by the adjusting wheel, and then the two take-up wheels collect the foil from different directions. This prevents friction between adjacent aluminum foil strips due to excessive proximity, avoids deformation or damage to the foil, and guarantees the quality of the cutting process.

[0039] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
