A conveying device for stainless steel strip processing

Abstract

The present invention discloses a conveying device for stainless steel strip processing, which relates to the technical field of stainless steel strip processing equipment and includes a frame, a conveying roller and a winding roller connected to the frame, and a pretreatment assembly. The pretreatment assembly includes a support roller rotatably connected to the frame, and an arc-shaped contact plate is arranged on the support roller. In the present invention, during the process of steel coil conveying, the first contact block is slowly moved to contact the first wedge block, driving the vertical movement of the arc-shaped contact plate, so that the arc-shaped contact plate contacts the steel strip. Since the arc-shaped contact plate has a certain curvature, when the steel strip passes through the arc-shaped contact plate, the force points with curvature on the arc-shaped contact plate can sequentially contact the conveyed steel strip, thereby performing different degrees of pretreatment on the conveyed steel strip, which is convenient for subsequent winding. The present invention is convenient for pretreating the steel strip before winding and can effectively improve the tightness of the steel strip after winding.

Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel strip processing equipment, and particularly to a conveying device for processing stainless steel strips. Background Art

[0002] Simply put, a stainless steel strip is an extension of an ultra-thin stainless steel plate. It is mainly a narrow and long steel plate produced to meet the needs of different industrial sectors for industrial production of various metal or mechanical products. As an important industrial material, it is widely used in various industries, including machinery manufacturing, chemical industry, food processing, etc.

[0003] During the processing of stainless steel strips, it is often necessary to convey them and wind the conveyed strips. During the winding process, in order to ensure the tightness of the wound strip, a roller that can press the strip is usually arranged above the winding roller to press the wound strip. However, only relying on the pressing during winding without pre-treating it, during the winding process of the strip, certain stress will accumulate inside it. If these stresses are not released or balanced through pre-treating bending, the strip may deform due to stress release during transportation, thereby reducing its tightness and may not achieve the same high tightness. Summary of the Invention

[0004] The purpose of the present invention is to provide a conveying device for processing stainless steel strips to solve the problems raised in the above background art.

[0005] To solve the above technical problems, a conveying device for processing stainless steel strips provided by the present invention includes a frame, a conveying roller and a winding roller connected to the frame, and includes

[0006] a pre-treatment component. The pre-treatment component includes a support roller rotatably connected to the frame. An arc-shaped contact plate is arranged on the support roller. The arc-shaped contact plate can vertically slide in a direction perpendicular to the central axis of the support roller. The arc-shaped contact plate can perform different degrees of pre-treatment on the strip when vertically moving to different positions. A first wedge block is connected to the bottom of the arc-shaped contact plate. A first contact block is horizontally slidably arranged in the support roller. The first contact block can be in contact with the first wedge block through sliding.

[0007] Further, a linkage component is also arranged in the frame. The linkage component includes a first bevel gear that rotates synchronously with the conveying roller. A second bevel gear is meshed and connected to one side of the first bevel gear. A first transmission gear that rotates synchronously with the second bevel gear is arranged on one side of the second bevel gear. A second transmission gear is meshed and connected to one side of the first transmission gear.

[0008] Further, a differential assembly is also provided inside the frame. The differential assembly includes a first connecting gear that rotates synchronously with the second transmission gear. A second connecting gear is meshed and connected to one side of the first connecting gear. The second connecting gear can drive the first abutting block to slide horizontally through rotation.

[0009] Further, the number of the first abutting blocks is multiple. The multiple first abutting blocks are arranged at equal intervals along the central axis direction of the support roller. A connecting block is slidably connected inside the support roller. All the multiple first abutting blocks are connected to the connecting block.

[0010] Further, a transmission lead screw is connected to the second connecting gear. A nut is threadedly connected to the transmission lead screw. A driving block is connected to the top of the nut. A second abutting block is connected to the driving block. A second wedge-shaped block is connected to one side of the connecting block. The second abutting block abuts against the second wedge-shaped block through horizontal movement.

[0011] Further, a plurality of connecting springs are connected to the support roller. The other ends of the connecting springs are connected to the arc-shaped abutting plate.

[0012] Further, a connecting frame is connected to the frame. A partition is connected inside the connecting frame. The first transmission gear and the second transmission gear are both rotatably connected to one side of the partition. The transmission lead screw is rotatably connected to the other side of the partition.

[0013] Further, a guide rod is connected to the connecting frame. The driving block is slidably connected to the guide rod. A sliding opening for the guide rod to slide is formed on the driving block.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. During the transportation of the steel coil, the first abutting block is slowly moved to abut against the first wedge-shaped block, driving the vertical movement of the arc-shaped abutting plate, so that the arc-shaped abutting plate abuts against the steel strip. Since the arc-shaped abutting plate has a certain curvature, when the steel strip passes through the arc-shaped abutting plate, at least three stress points (point a, point b, and point c) are provided on the arc-shaped abutting plate. The curvatures of the three stress points are different. As the arc-shaped abutting plate is continuously lifted, the three stress points with different curvatures on the arc-shaped abutting plate can sequentially contact the transported steel strip, thereby performing different degrees of pretreatment on the transported steel strip, facilitating subsequent winding. This setting facilitates the pretreatment of the steel strip before winding and can effectively improve the tightness of the steel strip after winding.

[0016] 2. By setting the linkage assembly, the pretreatment assembly can be adjusted to different degrees according to the transportation length and transportation time during the pretreatment of the transported steel coil, so as to better adapt to the steel strip winding drum with an increasing inner diameter.

[0017] 3. By setting the first transmission gear and the second transmission gear with different inner diameters, and the first connecting gear and the second connecting gear with different numbers of teeth, it can ensure that while using the conveying roller as the driving force of the pretreatment component, the pretreatment component can slowly preprocess the steel strip.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] During the processing of stainless steel strips, it is often necessary to convey them and wind the conveyed steel strips. During the winding process, in order to ensure the tightness of the wound steel strips, a roller that can press the steel strip is usually arranged above the winding roller to press the wound steel strip. However, relying solely on the pressing during winding without pre-treatment, certain stress will accumulate inside the steel strip during the winding process. If these stresses are not released or balanced through pre-treatment bending, the steel strip may deform due to stress release during transportation, thereby reducing its tightness and may not achieve the same high tightness.

[0029] In the present invention, it can be used in cooperation with the pressing roller for pressing, and pre-treat the stainless steel strip during the transportation of the stainless steel strip, so that the stainless steel strip can be bent to different degrees as the transportation time increases. Through the setting of the present invention, the stainless steel strip can be made more compact after winding, avoiding the situation of loose deformation that may occur due to poor tightness during the transportation of the stainless steel strip.

[0030] Please refer to Figures 1-8 , the present invention provides a technical solution: including a frame 1, a conveying roller 2 and a winding roller 3 connected to the frame 1, including a pre-treatment assembly 400. The pre-treatment assembly 400 includes a support roller 401 rotatably connected to the frame 1. An arc-shaped contact plate 402 is arranged on the support roller 401. The arc-shaped contact plate 402 can slide vertically along the direction perpendicular to the central axis of the support roller 401. The arc-shaped contact plate 402 moving vertically to different positions can perform different degrees of pre-treatment on the steel strip. A first wedge-shaped block 404 is connected to the bottom of the arc-shaped contact plate 402. A first contact block 403 is horizontally slidably arranged in the support roller 401. The first contact block 403 can be in contact with the first wedge-shaped block 404 through sliding.

[0031] To facilitate the arc-shaped contact plate 402 to rebound and return to its original position, a plurality of connecting springs 17 are connected to the support roller 401. The other ends of the connecting springs 17 are connected to the arc-shaped contact plate 402. The arranged connecting springs 17 can utilize their elastic potential energy to assist the arc-shaped contact plate 402 to return to its original position.

[0032] It should be noted that, please refer to Figure 1, the conveying roller 2 and the winding roller 3 connected to the frame 1 are fixedly arranged in sequence along the conveying direction of the stainless steel steel strip (the fixing method can be selected as bolts or welding). In this embodiment, it is fixed by bolts. On the frame 1 and at the bottom of the winding roller 3, a blanking cart 15 is slidably arranged. The blanking cart 15 is used to receive the wound steel strip and transport it. The blanking cart 15 is provided with a damper and a spring. The cooperation of the damper and the spring is convenient for buffering the steel strip falling on the blanking cart 15 and avoiding damage to the steel strip.

[0033] Furthermore, since the wound steel strip is in a cylindrical shape after being wound, and as the continuously wound steel coils are transported, the inner diameter of the wound cylindrical steel strip continuously increases. At this time, the transported steel strip needs to be pre-treated to different arcs to adapt to the steel strip cylinder with an increasing inner diameter. Therefore, at least three stress points (point a, point b, and point c) are provided on the arc-shaped contact plate 402. The arcs of the three stress points are different. As the arc-shaped contact plate 402 continuously rises, the three stress points with different arcs on the arc-shaped contact plate 402 can sequentially contact the transported steel strip, thereby pre-treating the transported steel strip to different degrees.

[0034] Specifically, please refer to Figures 2 to 8 , in this embodiment, before the steel strip is wound, the steel strip is pre-treated during transportation, which is convenient for pre-treating the steel strip before winding, thereby improving the tightness of the wound steel strip. During the transportation of the steel coil, the first contact block 403 is slowly moved to make the first contact block 403 contact the first wedge block 404, driving the vertical movement of the arc-shaped contact plate 402, so that the arc-shaped contact plate 402 contacts the steel strip. Since the arc-shaped contact plate 402 has a certain arc, when the steel strip passes through the arc-shaped contact plate 402, the arc-shaped contact plate 402 can bend the steel strip to a certain extent, which is convenient for subsequent winding.

[0035] Furthermore, to ensure that the whole steel coil can be pre-treated, please continue to refer to Figure 2 , the number of the first contact blocks 403 and the arc-shaped contact plates 402 is multiple. The multiple first contact blocks 403 are equidistantly arranged along the central axis direction of the support roller 401. A connecting block 12 is slidably connected in the support roller 401, and the multiple first contact blocks 403 are all connected to the connecting block 12;

[0036] The set first contact blocks 403 and the arc-shaped contact plates 402 corresponding to the first contact blocks 403 are both multiple, which is convenient for comprehensively pre-treating the steel strip. The provided connecting block 12 is convenient for synchronously driving the multiple first contact blocks 403 to move synchronously.

[0037] On the basis that the pre-treatment assembly 400 pre-treats the steel strip, to facilitate the adjustment of the transported steel coil to different degrees with the transportation length and time, please refer toFigure 2 , a linkage assembly 500 is further provided inside the frame 1. The linkage assembly 500 includes a first bevel gear 501 that rotates synchronously with the conveying roller 2. A second bevel gear 502 is meshed and connected to one side of the first bevel gear 501. A first transmission gear 503 that rotates synchronously with the second bevel gear 502 is provided on one side of the second bevel gear 502. A second transmission gear 504 is meshed and connected to one side of the first transmission gear 503;

[0038] It should be noted that since the conveying roller 2 is a conveying device for the conveying steel belt, its rotation speed is relatively fast. During the winding process of the winding roller 3, the inner diameter of the steel belt reel changes relatively slowly. Therefore, it is necessary to adjust the driving rotation speed of the conveying roller 2. For this reason, the inner diameter of the first transmission gear 503 is smaller than the inner diameter of the second transmission gear 504;

[0039] Specifically, the first bevel gear 501 and the second bevel gear 502 are first set up to drive the first transmission gear 503 to rotate during the rotation of the conveying roller 2. During the rotation of the first transmission gear 503, the second transmission gear 504 can be driven to rotate synchronously. When the second transmission gear 504 rotates, the arc-shaped abutting plate 402 can gradually rise to preprocess the steel belt.

[0040] Specifically, in order to further adjust the force for the conveying roller 2 to drive the arc-shaped abutting plate 402 to move, please continue to refer to Figure 3 , a differential assembly 600 is further provided inside the frame 1. The differential assembly 600 includes a first connecting gear 601 that rotates synchronously with the second transmission gear 504. A second connecting gear 602 is meshed and connected to one side of the first connecting gear 601. The second connecting gear 602 can drive the first abutting block 403 to slide horizontally through rotation;

[0041] It should be noted that the first connecting gear 601 is a special-shaped gear (the range of its teeth accounts for one-third or one-half or three-fourths of the circumference of the first connecting gear 601). In this embodiment, it is preferably one-half. The inner diameters of the first connecting gear 601 and the second connecting gear 602 are the same, that is, when the first connecting gear 601 rotates one circle, the second connecting gear 602 rotates half a circle, further adjusting the driving force of the conveying roller 2;

[0042] First, during the rotation of the second transmission gear 504, the first connecting gear 601 can be driven to rotate. As the first connecting gear 601 rotates, the second connecting gear 602 can be driven to rotate synchronously.

[0043] In order to facilitate the horizontal movement of the first abutting block 403 and make the arc-shaped abutting plate 402 move vertically, please continue to refer to Figure 6, a transmission lead screw 7 is connected to the second connecting gear 602. A nut 8 is threadedly connected to the transmission lead screw 7. A driving block 9 is connected to the top of the nut 8. A second abutting block 10 is connected to the driving block 9. A second wedge block 11 is connected to one side of the connecting block 12. The second abutting block 10 abuts against the second wedge block 11 through horizontal movement;

[0044] When the second connecting gear 602 rotates, the transmission lead screw 7 can rotate synchronously. At this time, the nut 8 threadedly connected to the transmission lead screw 7 can drive the driving block 9 and the second abutting block 10 to move horizontally. As the second abutting block 10 moves, it can gradually abut against the second wedge block 11 and drive the connecting block 12 to slide horizontally. During the sliding process of the connecting block 12, it can drive the first abutting block 403 to slide, so that the first abutting block 403 abuts against the first wedge block 404, thereby driving the arc-shaped abutting plate 402 to rise slowly;

[0045] Furthermore, to facilitate the stability of the movement of the driving block 9 and the second abutting block 10, a guide rod 13 is connected to the connecting frame 14. The driving block 9 is slidably connected to the guide rod 13. A sliding opening for the guide rod 13 to slide is formed in the driving block 9;

[0046] The provided guide rod 13 can provide a limiting and guiding effect on the sliding of the driving block 9, improving the stability of the driving block 9 during the sliding process.

[0047] For the convenience of installing the components inside the linkage assembly 500 and the differential assembly 600, please refer to Figure 1 , a connecting frame 14 is connected to the frame 1. A partition plate 16 is connected inside the connecting frame 14. The first transmission gear 503 and the second transmission gear 504 are both rotatably connected to one side of the partition plate 16. The transmission lead screw 7 is rotatably connected to the other side of the partition plate 16;

[0048] The provided connecting frame 14 facilitates the installation of the components inside the linkage assembly 500 and the differential assembly 600.

[0049] Working principle: When it is necessary to pre-treat the stainless steel strip:

[0050] First, the first bevel gear 501 and the second bevel gear 502 which are initially set can be used in cooperation to drive the first transmission gear 503 to rotate during the rotation of the conveying roller 2. During the rotation of the first transmission gear 503, it can drive the second transmission gear 504 to rotate synchronously. During the rotation of the second transmission gear 504, it can drive the first connecting gear 601 to rotate. As the first connecting gear 601 rotates, it can drive the second connecting gear 602 to rotate synchronously. When the second connecting gear 602 rotates, the transmission lead screw 7 can rotate synchronously. At this time, the nut 8 threadedly connected to the transmission lead screw 7 can drive the driving block 9 and the second abutting block 10 to move horizontally. As the second abutting block 10 moves, it can gradually abut against the second wedge-shaped block 11 and drive the connecting block 12 to slide horizontally. During the sliding of the connecting block 12, it can drive the first abutting block 403 to slide, so that the first abutting block 403 abuts against the first wedge-shaped block 404, thereby driving the arc-shaped abutting plate 402 to rise slowly. This setting facilitates the pretreatment of the stainless steel strip, facilitates the winding of the stainless steel strip, and ensures the tightness of the stainless steel strip after winding.
