Description

Technical Field

[0001] This utility model belongs to the technical field of slitting equipment, and in particular relates to a slitting device. Background Technology

[0002] Slitting equipment, also known as slitting line, slitting machine or stripping machine, is a mechanical device used for cutting metal. Its main function is to process metal coils into strips of the required width by slitting. It is suitable for processing cold-rolled and hot-rolled carbon steel, silicon steel, tinplate, stainless steel and various metal materials with surface coating. Slitting equipment is widely used for longitudinal shearing of metal strips and rewinding the slit narrow strips into coils.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing slitting equipment:

[0004] 1. When there is a large difference in diameter between the upper and lower blades, the larger diameter blade is heavier, making the disassembly and reassembly of the larger diameter blade more laborious and inconvenient to set up a reassembly and reassembly structure on the larger diameter blade.

[0005] 2. The end nut and the tightening cylinder are separate parts. During disassembly and assembly, the end nut and the tightening cylinder need to be removed and placed in turn, which results in low disassembly and assembly efficiency and inconvenience in connecting the end nut and the tightening cylinder. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a slitting device. This addresses the issues of existing devices where, when the diameter difference between the upper and lower blades is significant, the larger diameter blade is heavier, making disassembly and reassembly of the larger diameter blade laborious and inconvenient, and making it difficult to install a reassembly / reassembly structure on the larger diameter blade; the end nut and tightening cylinder are separate components, requiring sequential removal and reassembly during disassembly and assembly, resulting in low efficiency and inconvenience in connecting the end nut and tightening cylinder.

[0007] The purpose and effectiveness of this utility model's longitudinal shearing device are achieved through the following specific technical means:

[0008] A slitting device includes a device body; the device body is provided with circular blades arranged left and right, the circular blades having a through-hole in the center of the circular blades, and three arc-shaped holes through-holes in the left and right are arranged in a ring around the hexagonal holes of the circular blades. Circular spacers are provided between the circular blades, and the circular spacers have through-holes in the center of the circular spacers.

[0009] Furthermore, the threaded hole of the rotary locking cylinder is equipped with an anti-loosening and anti-rotation post in the vertical direction. The outer circumference of the anti-loosening and anti-rotation post is threaded, and the top end face of the anti-loosening and anti-rotation post is provided with a regular hexagonal groove.

[0010] Furthermore, a left-right limiting and tightening cylinder is installed inside the bearing ring groove of the rotary locking cylinder via a bearing. The center of the limiting and tightening cylinder has a through-hole regular hexagonal hole, and the outer circumference of the left end of the limiting and tightening cylinder has a bearing ring groove.

[0011] Furthermore, a left-right rotating locking cylinder is threadedly installed on the threaded post of the blade bearing shaft. The rotating locking cylinder has a threaded inner circumference, a bearing ring groove is formed on the inner circumference of the right end of the rotating locking cylinder, a regular hexagonal structure is provided on the outer circumference of the left side of the rotating locking cylinder, and a threaded hole that runs through the top and bottom is formed on the top wall of the left end of the rotating locking cylinder.

[0012] Furthermore, a regular hexagonal prism is provided on the right end face of the fixing post of the blade bearing shaft, a threaded post is provided on the left end face of the regular hexagonal rod of the blade bearing shaft, and a smooth post is provided on the left end face of the threaded post of the blade bearing shaft.

[0013] Furthermore, a limiting circular plate is provided on the right end face of the regular hexagonal rod of the blade bearing shaft, and a fixing post is provided on the right end face of the limiting circular plate of the blade bearing shaft.

[0014] Furthermore, a blade bearing shaft in the left-right direction is inserted into the regular hexagonal hole of the circular blade plate and the circular spacer plate, and a regular hexagonal rod is provided in the middle of the blade bearing shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] It allows for easy insertion of tools or hands into the arc-shaped slots of the circular blade plate to disassemble and retrieve it, making the disassembly and retrieval process more effortless. This solves the problem that when there is a large difference in diameter between the upper and lower blades, the larger diameter blade is heavier, making the disassembly and retrieval process of the larger diameter blade more laborious and inconvenient to set up a retrieval structure on the larger diameter blade.

[0017] The rotating locking cylinder and the limiting clamping cylinder are connected by bearings, which facilitates the simultaneous disassembly and assembly of the limiting clamping cylinder by rotating the locking cylinder. This solves the problem that the end nut and clamping cylinder are separate parts, which require the end nut and clamping cylinder to be removed and placed in turn during disassembly and assembly, resulting in low disassembly and assembly efficiency and inconvenience in connecting the end nut and clamping cylinder.

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 6 As shown:

[0028] This utility model provides a slitting device, including a device body 1. The device body 1 is provided with circular blade plates 2 arranged left and right for convenient slitting operations. The circular blade plates 2 have a through-hole regular hexagonal hole in the center for easy insertion and synchronous rotation of the blade support shaft 4. The outer periphery of the regular hexagonal hole of the circular blade plates 2 has three through-hole arc-shaped strip holes for easy insertion and removal of tools or hands. Circular spacers 3 are provided between the circular blade plates 2 to facilitate the placement of the upper blade between the circular blade plates 2. The circular spacers 3 have a through-hole regular hexagonal hole in the center for easy insertion and synchronous rotation of the blade support shaft 4. Blades in the left and right directions are inserted into the regular hexagonal holes of the circular blade plates 2 and the circular spacers 3. The blade support shaft 4 facilitates the rotation of the circular blade plate 2 and the circular spacer plate 3. A regular hexagonal rod is provided in the middle of the blade support shaft 4 to facilitate the synchronous assembly of the circular blade plate 2 and the circular spacer plate 3. A limiting circular plate is provided on the right end face of the regular hexagonal rod of the blade support shaft 4 to facilitate the limiting of the circular blade plate 2. A fixing post is provided on the right end face of the limiting circular plate of the blade support shaft 4 to facilitate installation via bearings. A regular hexagonal prism is provided on the right end face of the fixing post of the blade support shaft 4 to facilitate synchronous rotation with an external power device. A threaded post is provided on the left end face of the regular hexagonal rod of the blade support shaft 4 to facilitate the installation of the rotating locking cylinder 5 via threads. A smooth post is provided on the left end face of the threaded post of the blade support shaft 4 to facilitate contact with an external support device.

[0029] The blade bearing shaft 4 has a threaded post on which a left-right rotating locking cylinder 5 is threadedly installed, facilitating left-right movement of the rotating locking cylinder 5 through thread engagement. The rotating locking cylinder 5 has threads on its inner circumference for easy threaded installation. A bearing ring groove is formed on the inner circumference of the right end of the rotating locking cylinder 5, facilitating the installation of a limiting and tightening cylinder 6 via a bearing. A regular hexagonal structure is provided on the outer circumference of the left side of the rotating locking cylinder 5, facilitating rotation using a tool. A through-hole threaded hole is formed on the top wall of the left end of the rotating locking cylinder 5, facilitating the threaded installation of an anti-loosening and anti-rotation post 7. A left-right limiting and tightening cylinder is installed inside the bearing ring groove of the rotating locking cylinder 5 via a bearing. 6. The rotating locking cylinder 5 moves synchronously with the limiting and tightening cylinder 6 via the bearing. The limiting and tightening cylinder 6 has a through-hole regular hexagonal hole in the center, which facilitates its fitting onto the regular hexagonal rod of the blade bearing shaft 4. The outer circumference of the left end of the limiting and tightening cylinder 6 has a bearing ring groove, which facilitates the installation of the rotating locking cylinder 5 via the bearing. The threaded hole of the rotating locking cylinder 5 has an anti-loosening and anti-rotation post 7 installed in the vertical direction, which facilitates the anti-loosening and anti-rotation post 7 to tighten the blade bearing shaft 4 to prevent the rotating locking cylinder 5 from loosening. The outer circumference of the anti-loosening and anti-rotation post 7 has threads, which facilitates threaded installation. The top end face of the anti-loosening and anti-rotation post 7 has a regular hexagonal groove, which facilitates rotation and disassembly using tools.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In this utility model, such as Figure 1 As shown, the top of the equipment body 1 is an upper cutter roller. When longitudinally shearing the metal coil, the metal coil passes between the equipment body 1 and the upper cutter roller, thereby achieving longitudinal shearing of the metal coil. Figure 1 As shown, when disassembling the circular blade plate 2, the anti-loosening anti-rotation post 7 is rotated with a tool to engage with the rotating locking cylinder 5 through thread engagement. This causes the anti-loosening anti-rotation post 7 to rise through thread engagement and loosen its clamping on the blade bearing shaft 4. Consequently, the anti-loosening anti-rotation post 7 releases its anti-rotation function on the rotating locking cylinder 5. The rotating locking cylinder 5 is then rotated with a tool to engage with the rotating locking cylinder 4 through thread engagement. This causes the rotating locking cylinder 5 to move to the left through the thread engagement. The rotating locking cylinder 5 drives the limiting clamping cylinder 6 to move to the left simultaneously. This causes the rotating locking cylinder 5 and the limiting clamping cylinder 6 to move to the left and disengage from the blade bearing shaft 4. Consequently, the rotating locking cylinder 5 and the limiting clamping cylinder 6 release their restraint on the circular blade plate 2. Then, a tool or hand is inserted into the arc-shaped slot of the circular blade plate 2 to move the circular blade plate 2 to the left and disengage it from the blade bearing shaft 4. This completes the disassembly of the circular blade plate 2.

[0032] Example 2:

[0033] The difference from Embodiment 1 is that the hexagonal structure of the rotary locking cylinder 5 can also be set as a regular heptagonal structure, which makes the rotary locking cylinder 5 require a special tool that works with the regular heptagonal structure to rotate, thus preventing non-staff members from rotating and disassembling the rotary locking cylinder 5.

[0034] Example 3:

[0035] The difference from Embodiment 1 is that the regular hexagonal groove of the anti-loosening anti-rotation post 7 can also be set as a regular heptagonal groove, so that the anti-loosening anti-rotation post 7 can only be rotated by a special tool that cooperates with the regular heptagonal groove, thus preventing non-workers from rotating and disassembling the anti-loosening anti-rotation post 7.
