DETAILED DESCRIPTION

[0021] The embodiments of the present application will be described below by specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in the present specification. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] In combination with the description of the drawings Figures 1-4 The present application provides a longitudinal shearing machine convenient for replacing the cutter, which comprises a machine table 1, the machine table 1 is provided with a pair of supports 2, and the pair of supports 2 are rotationally connected with upper cutter shafts 3.

[0023] The upper cutter shafts 3 can provide longitudinal shearing power by the transmission system of the longitudinal shearing machine in the prior art.

[0024] In the present embodiment, the outer side of the upper cutter shaft 3 is provided with an assembly plate 4, the assembly plate 4 is provided with a through slot, and the size of the through slot is greater than that of the upper cutter shaft 3.

[0025] The through slot is arranged to facilitate the movement of the assembly plate 4 outside the upper blade shaft 3.

[0026] In the embodiment, the assembly plate 4 is provided with a longitudinal shearing transmission assembly 5, the longitudinal shearing transmission assembly 5 includes a gear one 51 rotatably connected to the side of the assembly plate 4, the gear one 51 is sequentially connected with a gear two 52 and a gear three 53, the gear two 52 is rotatably connected to the side of the assembly plate 4, and the assembly plate 4 is further rotatably connected with a mounting disc 54, the mounting disc 54 is fixedly connected to one end of the gear three 53.

[0027] The gear one 51 can obtain the rotating power of the upper blade shaft 3 to sequentially transmit the power to the gear two 52 and the gear three 53, so that the mounting disc 54 can make longitudinal shearing rotating movement, and the mounting disc 54 is arranged in a T-shaped structure in the application and penetrates through the assembly plate 4 at both ends, and one end of the mounting disc 54 can provide a mounting surface.

[0028] In the embodiment, the outer surface of the upper blade shaft 3 is fixedly connected with a key bar 9, and the gear one 51 is provided with a key groove, and the gear one 51 is movably connected to the upper blade shaft 3 and the key bar 9 through the key groove.

[0029] Since the gear one 51 is rotatably arranged on the assembly plate 4, the movement of the assembly plate 4 can drive the gear one 51 to move in the axial direction of the upper blade shaft 3, and the arrangement of the key bar 9 can conveniently drive the gear one 51 to rotate on the assembly plate 4 when the upper blade shaft 3 rotates.

[0030] In the embodiment, the longitudinal shearing transmission assembly 5 is connected with a longitudinal shearing blade 6 through bolts, and the longitudinal shearing blade 6 is connected to the mounting disc 54 through bolts.

[0031] After the mounting disc 54 obtains the rotating power, the longitudinal shearing blade 6 can perform longitudinal shearing processing on the material, and since the longitudinal shearing blade 6 and the upper blade shaft 3 are connected in different shafts in the application, the longitudinal shearing blade 6 is driven effectively, and the longitudinal shearing blade 6 is arranged to be directly connected by bolts to satisfy the disassembly and assembly of the longitudinal shearing blade 6 in an independent position, and since the traditional blade is coaxially assembled on the blade shaft, when a single blade needs to be replaced, the blade shaft needs to be disassembled and assembled, which is more troublesome.

[0032] It is worth noting that the gear one 51, the gear two 52 and the gear three 53 are arranged in three levels, so that the size of the gear can be restricted to prevent the size of the local gear from being greater than the size of the longitudinal shearing blade 6 and affecting the passing of the longitudinal shearing material.

[0033] In the embodiment, the assembly plate 4 is provided with a guide assembly, the guide assembly includes a pair of light rods 7, the pair of light rods 7 are fixedly connected to the pair of supports 2, a moving plate one 71 and a moving plate two 72 are slidably connected to the pair of light rods 7 respectively, and the moving plate one 71 and the moving plate two 72 are fixedly connected to the assembly plate 4.

[0034] The arrangement of the guide assembly can make the assembly plate 4 move along the axis of the light pole 7, so as to drive the assembly plate 4 and the structure thereon to move to facilitate adjustment of the slitting position of the slitting blade 6.

[0035] In the embodiment, the pair of supports 2 are provided with a fixing plate 8 for bolt connection with the guide assembly, the fixing plate 8 and the moving plate 71 are connected by bolts, and the fixing plate 8 is provided with a plurality of threaded grooves for bolt connection.

[0036] In order to stabilize the working position of the slitting blade 6 after adjustment, the guide assembly is locked by bolts, so as to limit the position of the slitting blade 6 on the assembly plate 4, and the arrangement of the plurality of threaded grooves can make the guide assembly be fixed by bolts at multiple points in the length direction of the fixing plate 8.

[0037] It is worth noting that the existing longitudinal slitting machine is provided with double knife shafts, i.e. the upper and lower longitudinal slitting cutters slitting the material, and only the cooperation of the upper knife shaft 3 and the slitting blade 6 is partially drawn and described in the present application, so that all the structures arranged between the pair of supports 2 can be mirror-imaged without affecting the technical improvement.
