Description

Technical Field

[0001] This utility model relates to the field of foil rolling mill technology, specifically a novel aluminum foil cutting knife. Background Technology

[0002] Aluminum foil rolling mills produce aluminum foil rolls of various thicknesses and widths by rolling aluminum foil blanks with a maximum thickness of 6mm through multiple passes. The finished products can be used for deep processing of aluminum foil, such as stamping, embossing, printing and coating, lamination, food and beverage packaging containers, packaging for pharmaceuticals, cosmetics and certain special materials, as well as raw materials for the manufacture of cables, heat exchangers, capacitors, building insulation and decoration materials, etc. In order to avoid strip breakage during the processing, foil cutting knives are often used to break the incoming aluminum coil strip to prevent a large amount of strip from quickly clogging the roll gap and causing accidents.

[0003] Chinese Utility Model Patent Publication No. CN 222519524 U discloses a foil-cutting device for an aluminum alloy foil rolling mill. This device uses a safety component with pins inserted into pin holes on a moving frame and a guard plate to prevent the moving frame and foil-cutting blade from falling downwards when the aluminum foil rolling mill is stopped. Furthermore, the device uses a limiting block and a limiting component to restrict the position of the moving frame, allowing it to stop rising after reaching a specified height. However, this foil-cutting device is not convenient for quick disassembly and installation of the foil blade, making maintenance and component replacement difficult, resulting in low equipment maintenance efficiency and high overall maintenance costs for the foil rolling mill, thus reducing its practicality. Summary of the Invention

An installation seat 4 is fixedly installed at the other end of the machine frame 1 far from the extension seat 3. A reinforcing block 5 with a "triangle" cross-section structure is fixedly installed at one end of the installation seat 4 close to the machine frame 1. The other end of the installation seat 4 far from the reinforcing block 5 is fixedly installed with a first fixing frame 6. The advantage is that the extension seat 3 and the installation seat 4 installed on the machine frame 1 provide a stable support structure for the equipment. The "triangle" structure design of the reinforcing block 5 can enhance the stability and strength of the connection between the installation seat 4 and the machine frame 1, and improve the stability of the overall machine.

The advantage is that in the lifting component 8, the first cylinder 802 is fixed on the fixing plate 801 through the first mounting frame 803 with a "U" cross-section structure. When receiving the signal of tape breakage, the first cylinder 802 can stably drive the foil cutting knife component 9 to perform the foil cutting operation, ensuring the accuracy and timeliness of the foil cutting action, avoiding the influence on the foil cutting effect due to the unstable installation of the cylinder, and preventing a large amount of strip materials from blocking the roll gap.

[0036] Specifically, the foil cutter assembly 9 includes a foil cutter base frame 901. A slot 902 is formed on the inner surface of the foil cutter base frame 901, and a threaded groove 903 is formed through the outer surface of the foil cutter base frame 901. A foil cutter mounting frame 904 is inserted into the foil cutter base frame 901 via the slot 902. The foil cutter base frame 901 is slidably connected to the second slide rail 12. The advantage is that the foil cutter base frame 901 in the foil cutter assembly 9 is inserted into the foil cutter mounting frame 904 via the slot 902 and slidably connected to the second slide rail 12. This design facilitates the installation and disassembly of the foil cutter assembly 9, making maintenance and replacement easier. Simultaneously, during foil cutting, the foil cutter base frame 901 can slide stably along the second slide rail 12, ensuring that the foil cutter assembly 9 accurately reaches the foil cutting position, quickly cutting the inlet aluminum coil strip and preventing the strip from clogging the roll gap.

[0037] Specifically, the outer surface of the foil knife mounting frame 904 has a second threaded groove 905, and a foil knife fixing frame 906 is inserted and installed on the inner surface of the foil knife mounting frame 904. The outer surface of the foil knife fixing frame 906 has a fixing groove 907, and the foil knife body 908 is inserted and installed on the inner surface of the foil knife fixing frame 906. A fixing bolt 909 is provided on the outer surface of the foil knife body 908. The lifting component 8 passes through the first threaded groove 903 and the second threaded groove 905 and extends to their outer surfaces. The fixing bolt 909 passes through the fixing groove 907 and the foil knife body 908 and extends to their outer surfaces. The advantage is that the foil... The foil knife mounting frame 904, foil knife fixing frame 906, and foil knife body 908 are connected and fixed through threaded groove 905, fixing groove 907, and fixing bolt 909, etc., and the lifting component 8 passes through threaded groove 903 and threaded groove 905. This structure makes the installation of foil knife body 908 more secure, and it can withstand greater shearing force during foil cutting operation, ensuring the foil cutting effect. Moreover, the installation method of foil knife body 908 can be selected according to the actual situation, and foil knife mounting frame 904 and foil knife body 908 can be quickly replaced, thereby improving its practicality.

[0038] Specifically, the moving roller assembly 11 includes a second cylinder 1101. A second mounting bracket 1102 is provided on the outer surface of the second cylinder 1101. A fixed seat 1103 and a bearing seat 1104 are fixedly mounted on the output shaft of the second cylinder 1101. The moving roller body 1105 is provided on the outer surface of the bearing seat 1104. A slider 1106 that is slidably connected to the first slide rail 7 is fixedly mounted on the outer surface of the fixed seat 1103. The advantage is that the second cylinder 1101 in the moving roller assembly 11 is mounted through the second mounting bracket 1102. The fixed seat 1103 and the bearing seat 1104 on its output shaft drive the moving roller body 1105 to move. The slider 1106 is slidably connected to the first slide rail 7, so that the moving roller body 1105 can be flexibly raised, lowered and moved to cooperate with the operation of the entire foil cutting knife device.

[0039] Working Principle: During operation, the frame 1 serves as the basic support structure for the entire device. It is equipped with a fixed roller 2, a first slide rail 7, a second slide rail 12, an extension seat 3, a mounting seat 4, and two fixing frames 6 and 10. The extension seat 3 and mounting seat 4, together with the reinforcing block 5, stabilize the frame 1, providing a stable mounting foundation for each component. When strip breakage occurs during strip rolling, the system receives a breakage signal. At this time, the first cylinder 802 in the lifting assembly 8 is activated. The first cylinder 802 is securely fixed to the fixing plate 801 via the first mounting frame 803. Its output shaft, through the mounting sleeve 804 and the limiting sleeve 805, drives the foil knife assembly 9 to descend rapidly along the second slide rail 12. In the foil knife assembly 9, the foil knife bottom frame 901 is connected to the foil knife mounting plate via the slot 902. The foil knife mounting frame 904 is connected, and the foil knife mounting frame 904 is further connected to the foil knife fixing frame 906 and the foil knife body 908 through the second threaded groove 905, the fixing groove 907 and the fixing bolt 909. The lifting component 8 passes through the first threaded groove 903 and the second threaded groove 905 to ensure that the foil knife body 908 descends stably to the foil cutting position, quickly cutting the inlet aluminum coil strip and preventing the strip from clogging the roller gap in large quantities. The second cylinder 1101 in the moving roller assembly 11 is installed through the second mounting bracket 1102. Its output shaft drives the fixing seat 1103 and the bearing seat 1104, so that the moving roller body 1105 can flexibly rise, fall and move on the first slide rail 7 through the slider 1106. During the foil cutting process, the moving roller assembly 11 adjusts the position and tension of the strip and cooperates with the foil knife assembly 9 to complete the foil cutting operation.
