The surfaces of the extended shafts on the upper and lower sides are provided with transmission gears for meshing with each other. The mutual meshing between the transmission gears is used to realize the rotational drive of the lower side placement cylinder to the upper side placement cylinder, so as to realize the relative rotation between the slitting circular knife and the matching knife groove, and slitting the aluminum alloy plate that is about to enter. During the slitting process, the winding equipment needs to be used to separately wind up the aluminum alloy plate at both ends.

[0016] 2. By rotating the adjustment knob, the rotating shaft can be rotated and the rotation angle of the worm can be adjusted.

Under the limit cooperation between the adjusting groove 3 and the mobile platform 9, the threaded cooperation between the adjusting screw 10 and the mobile platform 9 is utilized to realize the up and down movement of the mobile platform 9 inside the adjusting groove 3, so that the distance between the supporting components 5 on both sides is adjusted.

[0030] In the present application, the bearing assembly 5 includes a bearing ring 501, a limiting connecting column 502 is fixedly installed on the inner wall of the bearing ring 501, a combination plate 503 is fixedly installed on the lower end of the limiting connecting column 502, the limiting connecting column 502 is located inside the limiting slide groove 402, and the combination plate 503 is located inside the installation channel 403; A slitting circular knife 6 is installed on the outer side of the upper side bearing ring 501, and an extension seat 7 is installed on the outer side of the lower side bearing ring 501; A through sleeve 504 is rotatably arranged in the middle of the combined plate 503, and the through sleeve 504 is sleeved on the rod body of the driving rod 406.

A supporting protrusion 5051 is arranged on one side of the swing wheel 505.

[0031] In the specific configuration, a matching groove 5021 is provided inside the limiting connecting column 502, and extending through holes 5023 are provided on both sides of the matching groove 5021. Matching inclined blocks 5025 are movably installed on both sides of the matching groove 5021, and locking protrusions 5024 are fixedly installed on the outer sides of the matching inclined blocks 5025. The locking protrusions 5024 pass through the adjacent extending through holes 5023. A connecting bottom plate 5022 is provided at the bottom of the limiting connecting column 502, and a supporting protrusion 5026 is movably installed inside the connecting bottom plate 5022. The bottom of the supporting protrusion 5026 is limitedly matched with the supporting protrusion 5051, and an extension rod 5027 is fixedly installed on the upper end of the supporting protrusion 5026. A locking top plate 5029 is sleeved on the outer side of the extension rod 5027, and the locking top plate 5029 is limitedly matched with the matching inclined block 5025. The extension rod 5027 is provided with a return spring 5028, and the return spring 5028 is located between the extension rod 5027 and the locking top plate 5029.

[0032] When the supporting protrusion 5051 moves upward, it will contact the supporting protrusion rod 5026 and push the supporting protrusion rod 5026 upward. When pushing up, the extension rod 5027 and the locking top plate 5029 will also be pushed up, so that the locking top plate 5029 and the matching inclined blocks 5025 on both sides are limited and matched, and the matching inclined blocks 5025 on both sides move outward under the support of the locking top plate 5029, and the locking protrusions 5024 on both sides are extended outward and locked with the current limiting slide groove 402. The above structure can be used to lock a single bearing component 5, wherein the above structure can be used to uniformly cooperate with the driving rod 406, so that a single driving rod 406 can control the locking of multiple bearing components 5, so that the disassembly and assembly efficiency is improved.

[0033] In the specific setting, a limiting slide rail 5052 is arranged inside the swing wheel 505, and a matching arc plate 5053 is slidably installed inside the limiting slide rail 5052 on each side. A plurality of second right-angle teeth 5054 are arranged on the inner wall of the matching arc plate 5053, and the second right-angle teeth 5054 are meshed with the first right-angle teeth 4061.

[0034] Among them, grooves 5055 are respectively opened on both sides of the inner wall of the swing wheel 505, and a movable rod 5056 is movably installed inside the groove 5055. The movable rod 5056 is fixedly connected to the adjacent matching arc plate 5053. A support spring 5057 is arranged between the matching arc plate 5053 and the inner wall of the swing wheel 505, and the support spring 5057 is sleeved on the rod body of the movable rod 5056.

[0035] When the driving rod 406 rotates forward, the first right-angled tooth 4061 on the rod body of the driving rod 406 will mesh with the second right-angled tooth 5054 on the inner wall of the matching arc plate 5053. When fixed, the first right-angled tooth 4061 and the second right-angled tooth 5054 cooperate through the inclined surface. Through the above structure, the swing wheel 505 can be rotated and the supporting protrusion 5051 can be moved upward to realize the transmission of locking power. Since there is a certain error between each slitting circular knife 6, in order to be able to lock different slitting circular knives 6 and avoid loosening of individual slitting circular knives 6, during the rotation of the driving rod 406, the first right-angled tooth 4061 and the second right-angled tooth 5054 cooperate through the inclined surface. After one of the slitting circular knives 6 is locked, the support spring 5057 can be used to shrink to achieve continued locking of the remaining slitting circular knives 6, ensuring that each slitting circular knife 6 can be stably fixed; When the driving rod 406 reverses, the first right-angle tooth 4061 cooperates with the second right-angle tooth 5054 through the right-angle surface, so that the support spring 5057 will not shrink and will not affect the rotation of the swing wheel 505, so that the swing wheel 505 can be reversed and the support protrusion 5051 moves downward, thereby achieving the release of the locking fixation.

[0036] The working principle of this automatic cutting device for aluminum alloy plates: When in use, the aluminum alloy plate is first stored in the winding machine, and then the aluminum alloy plate passes through the slitting circular knife 6 and the matching knife groove 8, and the driving motor 2 is started to drive the connecting shaft 13 on one side to rotate, so as to realize the rotation of the lower end placement cylinder 401, wherein the surfaces of the extension shafts 404 on the upper and lower sides are provided with transmission gears 405 for meshing with each other, and the mutual meshing between the transmission gears 405 is used to realize the lower side placement cylinder 401 to rotate and drive the upper side placement cylinder 401, so as to realize the relative rotation between the slitting circular knife 6 and the matching knife groove 8, and the aluminum alloy plate that is about to enter is slit, and the slit aluminum alloy plate is stored in the other end of the winding machine; When adjusting the position of the slitting circular knife 6 and the matching knife groove 8, firstly, the adjusting motor 11 is started to drive the adjusting screw rod 10 to rotate, and under the limit cooperation between the adjusting groove 3 and the moving platform 9, the thread cooperation between the adjusting screw rod 10 and the moving platform 9 is utilized to realize the up and down movement of the moving platform 9 inside the adjusting groove 3, so that the spacing between the bearing components 5 on both sides is adjusted; Then, the rotating shaft 4071 can be rotated and the rotating angle of the worm 4072 can be adjusted by rotating the adjusting knob 4073. When the worm 4072 rotates, it will mesh with the outer side of the worm wheel 4062, thereby driving the worm wheel 4062 to rotate and causing the driving rod 406 to rotate. When the driving rod 406 reverses, the first right-angle tooth 4061 and the second right-angle tooth 5054 cooperate through the right-angle surface, so that the support spring 5057 will not shrink and will not affect the rotation of the swing wheel 505, so that the swing wheel 505 can reverse and the support protrusion 5051 moves downward, thereby realizing the release of the locking and fixing and adjusting the position. After adjusting the position, the driving rod 406 is rotated forward, and when the driving rod 406 is rotated forward, the first right-angle tooth 4061 on the rod body of the driving rod 406 will mesh with the second right-angle tooth 5054 on the inner wall of the matching arc plate 5053, wherein when fixed, the first right-angle tooth 4061 and the second right-angle tooth 5054 are matched through the inclined surface, and the above structure can make the swing wheel 505 rotate, and the supporting protrusion 5051 moves upward, so as to realize the transmission of locking power; When locking, when the support protrusion 5051 moves upward, it will contact the support protrusion rod 5026 and push the support protrusion rod 5026 upward. When pushing up, the extension rod 5027 and the locking top plate 5029 will also push up, so that the locking top plate 5029 and the matching inclined blocks 5025 on both sides are limited and matched, and the matching inclined blocks 5025 on both sides move outward under the support of the locking top plate 5029, and the locking protrusions 5024 on both sides are extended outward and locked with the current limited sliding groove 402, thereby completing synchronous locking; During the locking process, the first right-angle tooth 4061 and the second right-angle tooth 5054 are matched through the inclined surface. After one of the slitting circular knives 6 is locked, the contraction of the support spring 5057 can be used to continue locking the remaining slitting circular knives 6, ensuring that each slitting circular knife 6 can be stably fixed.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
