Description

Technical Field

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

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

[0003] In the process of stainless steel strip processing, it is often necessary to convey it and reel the conveyed steel strip. In the process of reeling, in order to ensure the tightness of the steel strip reeling, a roller that can press the steel strip is often set above the reeling roller to press the reeled steel strip. However, if only relying on the pressing during reeling without pretreatment, a certain amount of stress will accumulate inside the steel strip during the reeling process. If the stress is not released or balanced by pretreatment bending, the steel strip may be deformed due to stress release during transportation, thereby reducing its tightness and may not be able to achieve the same high tightness. Summary of the invention

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

[0005] In order to solve the above technical problems, the present invention provides a conveying device for processing stainless steel strips, comprising a frame, a conveying roller and a winding roller connected to the frame, comprising A pretreatment component, wherein the pretreatment component includes a support roller rotatably connected to a frame, wherein an arc-shaped contact plate is provided on the support roller, wherein the arc-shaped contact plate can slide vertically in a direction perpendicular to the central axis of the support roller, wherein the arc-shaped contact plate can be moved vertically to different positions to perform different degrees of pretreatment on the steel strip, wherein a first wedge block is connected to the bottom of the arc-shaped contact plate, wherein a first contact block is provided in the support roller for horizontal sliding, wherein the first contact block can contact the first wedge block by sliding.

[0006] Furthermore, a linkage assembly is provided in the frame, and the linkage assembly includes a first bevel gear that rotates synchronously with the conveying roller, one side of the first bevel gear is meshed and connected with a second bevel gear, one side of the second bevel gear is provided with a first transmission gear that rotates synchronously with the second bevel gear, and one side of the first transmission gear is meshed and connected with the second transmission gear.

[0007] Furthermore, a differential assembly is provided in the frame, and the differential assembly includes a first connecting gear that rotates synchronously with the second transmission gear, one side of the first connecting gear is meshedly connected to the second connecting gear, and the second connecting gear can drive the first contact block to slide horizontally by rotating.

[0008] Furthermore, there are multiple first resistance blocks, which are arranged at equal intervals along the central axis direction of the support roller. A connecting block is slidably connected inside the support roller, and the multiple first resistance blocks are all connected to the connecting block.

[0009] Furthermore, a transmission screw is connected to the second connecting gear, a nut is threadedly connected to the transmission screw, a driving block is connected to the top of the nut, a second interference block is connected to the driving block, a second wedge block is connected to one side of the connecting block, and the second interference block interferes with the second wedge block through horizontal movement.

[0010] Furthermore, a plurality of connection springs are connected to the support roller, and the other ends of the connection springs are connected to the arc-shaped abutment plate.

[0011] Furthermore, 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, and the transmission screw is rotatably connected to the other side of the partition.

[0012] Furthermore, the connecting frame is connected to a guide rod, the driving block is slidably connected to the guide rod, and the driving block is provided with a sliding opening for the guide rod to slide.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. During the conveying process of the steel coil, the first resistance block is slowly moved to make the first resistance block contact with the first wedge block, thereby driving the vertical movement of the arc resistance plate to make the arc resistance plate contact with the steel strip. Since the arc resistance plate has a certain curvature, when the steel strip passes through the arc resistance plate, at least three force points (point a, point b and point c) are arranged on the arc resistance plate. The curvatures of the three force points are different. As the arc resistance plate is continuously lifted, the three force points with different curvatures on the arc resistance plate can contact the conveyed steel strip in turn, thereby pre-treating the conveyed steel strip to different degrees, which is convenient for subsequent winding. This arrangement is convenient for pre-treating the steel strip before winding, and can effectively improve the compactness of the steel strip after winding.

[0014] 2. Through the linkage assembly, the pretreatment assembly can be adjusted to different degrees according to the conveying length and conveying time when pretreatment is performed on the conveyed steel coil, so as to better adapt to the steel belt winding drum with increasing inner diameter.

[0015] 3. By providing 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 be ensured that the conveying roller is used as the driving force of the pretreatment component and the pretreatment component can pretreatment the steel strip slowly.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] During the processing of stainless steel strips, it is often necessary to transport them and reel the transported steel strips. During the reeling process, in order to ensure the tightness of the steel strips, a roller that can press the steel strips is often set above the reeling roller to press the reeled steel strips. However, if the steel strips are only pressed during reeling without pretreatment, certain stresses will accumulate inside the steel strips during the reeling process. If the stresses are not released or balanced by pretreatment bending, the steel strips may be deformed during transportation due to stress release, thereby reducing their tightness and may not be able to achieve the same high tightness. The present invention can be used in conjunction with a pressing roller to pre-treat the stainless steel belt during its transportation, so that the stainless steel belt can be bent to varying degrees as the transportation time increases. The arrangement of the present invention can make the stainless steel belt tighter after winding, thereby avoiding loose deformation due to poor tightness during transportation of the stainless steel belt.

[0020] See also Figure 1-8 The present invention provides a technical solution: it includes a frame 1, a conveying roller 2 and a winding roller 3 connected to the frame 1, and a pretreatment component 400. The pretreatment component 400 includes a supporting roller 401 rotatably connected to the frame 1, and an arc-shaped contact plate 402 is provided on the supporting roller 401. The arc-shaped contact plate 402 can slide vertically in a direction perpendicular to the central axis of the supporting roller 401. The arc-shaped contact plate 402 can be moved vertically to different positions to perform different degrees of pretreatment on the steel strip. The bottom of the arc-shaped contact plate 402 is connected to a first wedge block 404. A first contact block 403 is horizontally slidably provided in the supporting roller 401, and the first contact block 403 can contact the first wedge block 404 by sliding.

[0021] In order to facilitate the arc-shaped resistance plate 402 to rebound to its original position, a plurality of connecting springs 17 are connected to the support roller 401, and the other end of the connecting spring 17 is connected to the arc-shaped resistance plate 402. The set connecting spring 17 can use its elastic potential energy to assist the arc-shaped resistance plate 402 to return to its original position.

[0022] Please note 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 strip (the fixing method can be selected to be fixed by bolts or welding). In this embodiment, it is fixed with bolts. A feeding trolley 15 is slidably arranged on the frame 1 and located at the bottom of the winding roller 3. The feeding trolley 15 is used to receive the wound steel strip and transport it. A damper and a spring are arranged in the feeding trolley 15. The coordinated use of the damper and the spring facilitates the buffering of the steel strip falling on the feeding trolley 15 to avoid damage to the steel strip.

[0023] Furthermore, since the wound steel strip is in a cylindrical shape after being wound, and as the conveyed steel coil is continuously wound, the inner diameter of the wound cylindrical steel strip continues to increase. At this time, the conveyed steel strip needs to be preprocessed into different curvatures to adapt to the steel strip cylinder with an increasing inner diameter. Therefore, at least three force points (point a, point b and point c) are provided on the arc-shaped contact plate 402. The curvatures of the three force points are different. As the arc-shaped contact plate 402 is continuously lifted, the three force points with different curvatures on the arc-shaped contact plate 402 can contact the conveyed steel strip in turn, thereby preprocessing the conveyed steel strip to different degrees.

[0024] For details, please refer to Figures 2 to 8 In this embodiment, the steel strip is pre-treated during transportation before being wound, so as to facilitate the pre-treatment of the steel strip before being rolled, thereby improving the compactness of the steel strip after being rolled. During the transportation of the steel coil, the first resistance block 403 is slowly moved to make the first resistance block 403 collide with the first wedge block 404, thereby driving the arc-shaped resistance plate 402 to move vertically, so that the arc-shaped resistance plate 402 conflicts with the steel strip. Since the arc-shaped resistance plate 402 has a certain curvature, when the steel strip passes through the arc-shaped resistance plate 402, the arc-shaped resistance plate 402 can bend the steel strip to a certain extent, so as to facilitate subsequent rolling.

[0025] Further, in order to ensure that the entire steel coil can be pre-processed, please continue to refer to Figure 2 The number of the first resistance block 403 and the arc-shaped resistance plate 402 are both multiple, and the multiple first resistance blocks 403 are arranged at equal intervals along the central axis direction of the support roller 401. The support roller 401 is slidably connected with a connecting block 12, and the multiple first resistance blocks 403 are all connected to the connecting block 12; There are multiple first resistance blocks 403 and arc-shaped resistance plates 402 corresponding to the first resistance blocks 403, which is convenient for comprehensive pretreatment of the steel strip. The connection block 12 is provided to facilitate synchronous driving of multiple first resistance blocks 403 to move synchronously.

[0026] On the basis of the pretreatment of the steel strip by the pretreatment component 400, in order to facilitate the conveying of the steel coil, the conveying length and conveying time can be adjusted to different degrees. Please refer to Figure 2 The frame 1 is also provided with a linkage assembly 500, which includes a first bevel gear 501 that rotates synchronously with the conveying roller 2, one side of the first bevel gear 501 is meshedly connected with a second bevel gear 502, one side of the second bevel gear 502 is provided with a first transmission gear 503 that rotates synchronously with the second bevel gear 502, and one side of the first transmission gear 503 is meshedly connected with a second transmission gear 504; It should be noted that, since the conveying roller 2 is used as a conveying device for conveying the steel strip, its rotation speed is relatively fast, and the inner diameter of the steel strip reel changes relatively slowly during the winding process of the winding roller 3, so it is necessary to adjust the driving speed of the conveying roller 2, and for this purpose, the inner diameter of the first transmission gear 503 is smaller than the inner diameter of the second transmission gear 504; Specifically, the first bevel gear 501 and the second bevel gear 502 that are first set can be used in conjunction to drive the first transmission gear 503 to rotate during the rotation of the conveying roller 2, and the first transmission gear 503 can drive the second transmission gear 504 to rotate synchronously during the rotation process. When the second transmission gear 504 rotates, the arc-shaped contact plate 402 can gradually rise to pre-treat the steel strip.

[0027] Specifically, in order to further adjust the force of the conveying roller 2 driving the arc-shaped contact plate 402 to move, please continue to refer to Figure 3 A differential assembly 600 is also provided in the frame 1, and the differential assembly 600 includes a first connecting gear 601 that rotates synchronously with the second transmission gear 504, and a second connecting gear 602 is meshedly connected to one side of the first connecting gear 601, and the second connecting gear 602 can drive the first contact block 403 to slide horizontally by rotating; It should be noted that the first connecting gear 601 is a special-shaped gear (its teeth occupy a range of one-third, one-half or three-quarters of the circumference of the first connecting gear 601). In this embodiment, it is preferably one-half. The inner diameter of the first connecting gear 601 is the same as that of the second connecting gear 602, that is, the first connecting gear 601 rotates one circle, and the second connecting gear 602 rotates half a circle, which further adjusts the driving force of the conveying roller 2. First, the second transmission gear 504 can drive the first connecting gear 601 to rotate during the rotation process, and the first connecting gear 601 can drive the second connecting gear 602 to rotate synchronously during the rotation process.

[0028] In order to facilitate the horizontal movement of the first resistance block 403 and the vertical movement of the arc resistance plate 402, please continue to refer to Figure 6 The second connecting gear 602 is connected with a transmission screw 7, the transmission screw 7 is threadedly connected with a nut 8, the top of the nut 8 is connected with a driving block 9, the driving block 9 is connected with a second abutting block 10, one side of the connecting block 12 is connected with a second wedge block 11, and the second abutting block 10 abuts against the second wedge block 11 by horizontal movement; When the second connecting gear 602 rotates, the transmission screw 7 can rotate synchronously. At this time, the nut 8 threadedly connected to the transmission screw 7 can drive the driving block 9 and the second contact block 10 to move horizontally. As the second contact block 10 moves, it can gradually contact the second wedge block 11 and drive the connecting block 12 to slide horizontally. During the sliding process, the connecting block 12 can drive the first contact block 403 to slide, so that the first contact block 403 and the first wedge block 404 contact each other, thereby driving the arc-shaped contact plate 402 to rise slowly. Furthermore, in order 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, and a sliding opening for the guide rod 13 to slide is opened on the driving block 9; The guide rod 13 can provide a limiting and guiding effect on the sliding of the driving block 9, thereby improving the stability of the driving block 9 during the sliding process.

[0029] To facilitate the installation of the components in 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 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 16, and the transmission screw 7 is rotatably connected to the other side of the partition 16; The connection frame 14 is provided to facilitate installation of components in the linkage assembly 500 and the differential assembly 600 .

[0030] Working principle: When the stainless steel strip needs to be pre-treated: The first bevel gear 501 and the second bevel gear 502 that are first set can be used in conjunction with each other to drive the first transmission gear 503 to rotate during the rotation of the conveying roller 2, and the first transmission gear 503 can drive the second transmission gear 504 to rotate synchronously during the rotation process, and the second transmission gear 504 can drive the first connecting gear 601 to rotate during the rotation process, and the first connecting gear 601 can drive the second connecting gear 602 to rotate synchronously during the rotation process, and when the second connecting gear 602 rotates, the transmission screw 7 can rotate synchronously. At this time The nut 8 threadedly connected on the transmission screw 7 can drive the driving block 9 and the second contact block 10 to move horizontally. As the second contact block 10 moves, it can gradually contact the second wedge block 11 and drive the connecting block 12 to slide horizontally. During the sliding process, the connecting block 12 can drive the first contact block 403 to slide, so that the first contact block 403 and the first wedge block 404 contact each other, thereby driving the arc-shaped contact plate 402 to rise slowly. This arrangement is convenient for pre-processing of the stainless steel strip, convenient for winding of the stainless steel strip, and ensures the tightness of the stainless steel strip after winding.
