Description

Technical Field

[0001] This utility model relates to the field of stainless steel rolling processing technology, and in particular to an automatic unloading edge trimming device for stainless steel rolling processing. Background Technology

[0002] In the production and processing of stainless steel strip, rolling is one of the key processes. After multiple rolling passes, stainless steel strip often suffers from uneven edges and inconsistent widths, affecting subsequent processing and product quality. Therefore, after the rolling process, the strip is usually trimmed on both sides using edge trimming equipment to ensure dimensional accuracy and surface quality.

[0003] Stainless steel strip often exhibits irregular deformations such as localized warping and wrinkling after rolling. Traditional edge-cutting equipment lacks an effective dynamic tension compensation structure, leading to problems such as strip misalignment, blade jamming, or uneven cutting edges during the cutting process, affecting cutting accuracy and production continuity. Furthermore, in actual production, the waste edge collection tray frequently needs replacement when it is full. However, traditional structures often use bolt fixing or overall disassembly methods, resulting in time-consuming and labor-intensive replacement processes that severely impact equipment operating efficiency and automation levels, and hinder rapid response to production demands.

[0012] Preferably, a trapezoidal locking block is fixedly connected to the outer wall of the guide rod, the trapezoidal locking block passes through the receiving rod and extends to the outside, a locking groove is opened on the outer wall of the receiving tray, and a convex sliding plate is fixedly connected to the inner wall of the mounting cavity, the side wall of the convex sliding plate is slidably connected to the inner wall of the trapezoidal locking block.

[0013] Preferably, a placement plate is fixedly connected to the inner side of the fixing frame, and a waste trough is provided on the top of the placement plate.

[0014] The beneficial effects of this application are:

[0015] 1. This stainless steel rolling processing automatic feeding and edge trimming device allows the stainless steel strip to pass through the tensioning wheel after rolling. A helical spring, through its elastic action, pushes the connecting seat, causing it to slide downwards along the limiting slide bar. This drives the tensioning wheel to press down and contact the surface of the stainless steel strip, applying a constant tension force to the material. This effectively eliminates slack caused by uneven tension or external disturbances during strip operation, achieving flat and tight compression of the strip. Simultaneously, if the strip experiences localized warping or wrinkling during cutting, the helical spring, through its elastic adaptive adjustment mechanism, drives the tensioning wheel to press down accordingly, compensating for strip deformation in real time and maintaining a continuous and stable tension state, further ensuring the stability and reliability of the entire edge trimming process.

[0016] 2. This stainless steel rolling processing automatic feeding and trimming device, after completing the trimming process, ensures that the stainless steel strip maintains good flatness and operational stability during subsequent processing or coiling. The operator can drive the double-ended threaded rod to rotate by rotating the handle, causing two L-shaped positioning plates meshing with it to move synchronously in opposite directions along the slide rail. This achieves precise positioning and guiding adjustment of stainless steel strips of different widths, ensuring that the centerline of the stainless steel strip remains consistent with the axis of the trimming device during conveying. Simultaneously, the L-shaped positioning plates guide and straighten the strip edges, preventing bending or wavy deformation from affecting subsequent cutting accuracy and coiling quality.

[0017] 3. This stainless steel rolling processing automatic unloading trimming device, when it is necessary to replace a fully loaded take-up reel, the operator first presses the pressing plate, causing the guide chute plate to move synchronously. The guide rod slides within the limiting groove of the guide chute plate, and is guided by its inclined surface to retract radially into the mounting cavity, thereby driving the trapezoidal locking block to move synchronously inward. As the trapezoidal locking block disengages from the locking groove, the locking state between the take-up reel and the take-up rod is released. At this time, the take-up reel can be removed axially from the take-up rod to complete the disassembly operation. When replacing with a new take-up reel... The tray is fitted onto the end of the receiving rod and pushed axially. The front end of the receiving tray first contacts the inclined surface of the trapezoidal locking block. Under the action of thrust, the trapezoidal locking block is forced to retract further into the mounting cavity. When the receiving tray is fully in place, the return spring pushes the pressing plate back to the initial position, and at the same time drives the guide inclined plate, guide rod and trapezoidal locking block to reset, so that the trapezoidal locking block automatically inserts into the corresponding slot, realizing reliable locking and positioning of the new receiving tray. This realizes the quick loading and unloading function of the receiving tray, which significantly improves the efficiency of equipment use and the convenience of maintenance.

It also includes:

[0028] A cutting frame 21 is fixedly connected to the top of the support 101. A cutting motor 201 is fixedly connected to the side wall of the cutting frame 21. A drive rod 202 is fixedly connected to the output end of the cutting motor 201. An upper disc cutter 203 is fixedly connected to the outer wall of the drive rod 202.

A lower disc cutter 207 is fixedly connected to the outer wall of the driven roller 206. This arrangement is so that the cutting motor 201 drives the upper disc cutter 203 to rotate at high speed through the drive rod 202. At the same time, the drive gear 204 on the drive rod 202 rotates accordingly and meshes with the driven gear 205 for transmission. Driven gear 205 is fixedly connected to the shaft end of driven roller 206, thereby driving the lower disc cutter 207 to rotate synchronously, forming an upper and lower shearing cooperation structure. When the stainless steel strip runs between the lower disc cutter 207 and the upper disc cutter 203, the two cutters rotate in opposite directions and form a shearing action.

[0029] A fixed frame 301 is fixedly connected to the side wall of the trimming frame 21. A limiting slide rod 302 is fixedly connected to the bottom of the fixed frame 301. A connecting seat 303 is slidably connected to the outer wall of the limiting slide rod 302. A helical spring 304 is fixedly connected to the top of the connecting seat 303.

A tensioning wheel 305 is rotatably connected to the through hole of the connecting seat 303. This is designed so that the tensioning wheel 305 can apply tension to the stainless steel strip to prevent it from deviating. A placement plate 31 is fixedly connected to the inner side of the fixed frame 301. A waste trough 32 is opened on the top of the placement plate 31. This is designed so that the waste trough 32 can guide the waste edge material for easy subsequent cleaning and recycling.

[0030] The inner side of the trimming frame 21 is fixedly connected to a slide rail 401. Two L-shaped positioning plates 402 are slidably connected to the side wall of the slide rail 401. A double-threaded rod 403 is meshed through the side wall of the two L-shaped positioning plates 402. A throttle 404 is fixedly connected to one end of the double-threaded rod 403. This arrangement drives the double-threaded rod 403 to rotate by rotating the throttle 404, which in turn drives the two L-shaped positioning plates 402 that mesh with it to move synchronously in opposite directions along the slide rail 401.

[0031] A support frame 501 is fixedly connected to the top of the support base 101. A receiving motor 502 is fixedly connected to the inner wall of the support frame 501. A receiving rod 503 is fixedly connected to the output end of the receiving motor 502. A receiving tray 504 is sleeved on the outer wall of the receiving rod 503.

[0032] The receiving rod 503 has an installation cavity 51 at the end away from the receiving motor 502. A return spring 52 is fixedly connected to the inner wall of the installation cavity 51. A pressing plate 53 is fixedly connected to the right end of the return spring 52. A guide inclined plate 54 is fixedly connected to the inner side of the pressing plate 53. A guide rod 55 is slidably connected to the inner wall of the guide inclined plate 54. This is designed so that the guide inclined plate 54 guides the guide rod 55. A trapezoidal locking block 56 is fixedly connected to the outer wall of the guide rod 55. The trapezoidal locking block 56 passes through the receiving rod 503 and extends to the outside. A slot 57 is opened on the outer wall of the receiving tray 504. This is designed so that the trapezoidal locking block 56 can be engaged in the slot 57. A convex sliding plate 58 is fixedly connected to the inner wall of the installation cavity 51. The side wall of the convex sliding plate 58 is slidably connected to the inner wall of the trapezoidal locking block 56.

[0033] In summary, the working principle of the automatic unloading trimming device for stainless steel rolling processing according to this utility model embodiment is as follows: the stainless steel coil is unwound by the unwinding roller 102 and sequentially conveyed to the rolling mill 104 for rolling and forming. After rolling, the stainless steel strip falls flat onto the placement plate 31, providing stable support for the subsequent trimming process. Subsequently, the cutting motor 201 starts and drives the upper disc cutter 203 to rotate at high speed through the drive rod 202. At the same time, the drive gear 204 on the drive rod 202 rotates accordingly and meshes with the driven gear 205 for transmission. Driven gear 205 is fixedly connected to the shaft end of driven roller 206, thereby driving the lower disc cutter 207 to rotate synchronously, forming an upper and lower shearing cooperation structure. When the stainless steel strip runs between the lower disc cutter 207 and the upper disc cutter 203, the two cutters rotate in opposite directions and form a shearing action to trim the strip, remove irregular edges, and improve the dimensional accuracy and appearance quality of the finished product. The waste edge material generated during the cutting process slides down along the waste trough 32 and is collected in a concentrated manner, achieving the purpose of clean production and automated unloading. The stainless steel strip that has completed the edge trimming process continues to be conveyed and is finally automatically wound up by the winding roller 103 to complete the entire processing flow.

[0034] After the stainless steel strip undergoes rolling, it passes under the tensioning wheel 305. The helical spring 304, through its elastic action, pushes the connecting seat 303, causing it to slide downwards along the limiting slide bar 302. This causes the tensioning wheel 305 to press down and contact the surface of the stainless steel strip, thereby applying a constant tension force to the material. This effectively eliminates slack caused by uneven tension or external disturbances during strip operation, achieving flat and tight clamping of the strip. Simultaneously, if the strip experiences local warping or wrinkling during cutting, the helical spring 304 can drive the tensioning wheel 305 downwards through an elastic adaptive adjustment mechanism, compensating for strip deformation in real time and maintaining a continuous and stable tension state, further ensuring the stability and reliability of the entire edge-cutting process.

[0035] After the edge trimming process is completed, to ensure that the stainless steel strip maintains good flatness and operational stability during subsequent processing or coiling, the operator can drive the double-ended threaded rod 403 to rotate by rotating the throttle 404. This causes the two L-shaped positioning plates 402 meshing with it to move synchronously in opposite directions along the slide rail 401. This achieves precise positioning and guiding adjustment of stainless steel strips of different widths, ensuring that the centerline of the stainless steel strip remains consistent with the axis of the edge trimming device during the conveying process. At the same time, the L-shaped positioning plates 402 guide and straighten the edges of the strip, preventing bending or wavy deformation from affecting subsequent cutting accuracy and coiling quality.

[0036] During the edge trimming process, the metal scrap edges generated slide down the scrap groove 32 on the placement plate 31. The workers embed the scrap edges into the slots 505 opened on the outer wall of the receiving tray 504 to achieve initial positioning and guidance. When the receiving motor 502 drives the receiving rod 503 to rotate, the receiving rod 503 drives the receiving tray 504 to rotate synchronously. Since the slots 505 have a limiting and guiding effect on the scrap edges, as the receiving tray 504 rotates continuously, the scrap edges are gradually wrapped and rolled up on its surface, forming an orderly accumulation. This realizes the automatic collection and centralized sorting of edge trimming scrap, effectively avoiding the messy working environment and safety hazards caused by the scattering of scrap.

[0037] When it is necessary to replace the fully loaded take-up reel 504, the operator first presses the pressing plate 53, causing the guide sloping plate 54 to move synchronously. The guide rod 55 slides in the limiting groove of the guide sloping plate 54 and is guided by its inclined surface to retract radially into the mounting cavity 51, thereby driving the trapezoidal locking block 56 to move inward synchronously. As the trapezoidal locking block 56 disengages from the locking groove 57, the locking state between the take-up reel 504 and the take-up rod 503 is released. At this time, the take-up reel 504 can be removed from the take-up rod 503 axially to complete the disassembly operation.

[0038] When replacing the new receiving tray 504, it is fitted onto the end of the receiving rod 503 and pushed axially. The front end of the receiving tray 504 first contacts the inclined surface of the trapezoidal locking block 56. Under the action of the thrust, the trapezoidal locking block 56 is forced to further retract into the mounting cavity 51. When the receiving tray 504 is fully in place, the return spring 52 pushes the pressing plate 53 back to the initial position, and at the same time drives the guide inclined plate 54, guide rod 55 and trapezoidal locking block 56 to reset, so that the trapezoidal locking block 56 automatically inserts into the corresponding slot 57, realizing reliable locking and positioning of the new receiving tray 504, realizing the quick loading and unloading function of the receiving tray 504, and significantly improving the efficiency of equipment use and the convenience of maintenance.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
