Description

Technical Field

[0001] This invention belongs to the field of strip steel rolling technology, specifically a galvanized strip steel rolling device for cable tray production. Background Technology

[0002] Cable trays can be installed independently within buildings or attached to various building structures and pipe rack supports. They feature a simple structure, attractive appearance, flexible configuration, and ease of maintenance. All parts are galvanized. Outdoor cable trays consist of various components, including trough-type, tray-type, or ladder-type components, as well as brackets and hangers, providing tight support for cables. Cable trays are primarily made of high-quality cold-rolled steel plates, with surfaces treated by cold galvanizing and hot-dip galvanizing. The galvanized steel strips undergo multiple processing steps.

[0003] A patent with publication number CN115569984A discloses a galvanized strip rolling equipment for cable tray production, including a rolling motor, a drive roller, a driven roller, and a connecting frame. The driven roller has two annular grooves machined on its surface. A reducer is driven to one side of the rolling motor, and a reduction drive shaft is internally located on one side of the reducer. A drive prism is fixedly connected to one end of the reduction drive shaft. Both sides of the connecting frame are fixedly connected to leaf plates, and the two leaf plates at one end are internally connected to the same U-shaped plate. Through the rolling motor and reducer, the reduction drive shaft on one side of the reducer drives the drive prism to rotate, thereby driving the drive roller to rotate via the roller shaft. During the rolling process of the galvanized strip by the drive roller and driven roller, the bottom outer wall of the U-shaped plate inside the two leaf plates connected to one end continuously contacts the surface of the drive roller, preventing the rolled galvanized strip from stretching in the lateral direction.

[0004] However, during the actual rolling process of existing galvanized strip steel rolling equipment for cable tray production, the mechanical vibration generated during equipment operation is difficult to completely eliminate. This vibration is transmitted to the steel plate being rolled. When the steel plate is continuously squeezed and deformed by the rollers, the vibration causes uneven local stress, resulting in abnormal expansion of some steel plates in the width direction. Ultimately, some areas of the rolled steel plate exceed the standard width range. In the subsequent coiling process, these steel plates with excessive width cannot be flatly attached to other parts, resulting in local bulges, wrinkles, or misalignment on the surface of the coiled steel. This not only reduces the overall appearance quality of the coiled steel but also causes fluctuations in coiling tension, resulting in loosening or even collapse of the coil core. This can lead to equipment jamming, shutdown for maintenance, and reduced production efficiency and product qualification rate.

[0005] Therefore, the present invention provides a galvanized strip steel rolling device for cable tray production. Summary of the Invention

A ranging head is fixed to the upper surface of the second rack plate.

[0009] Preferably, a fixing groove is provided on one side of the push plate, and a plurality of rotating wheels are rotatably connected in the fixing groove. The rotating wheels are used to assist the movement of the rolled steel plate.

[0010] Preferably, the collecting assembly includes a first guide rail fixed to one side of the fixed plate, a first guide groove is provided in the first guide rail, a slide rod is slidably connected in the first guide groove, and a cutting wheel is rotatably arranged inside the slide rod, the cutting wheel being used to cut the extended portion of the steel plate.

[0011] Preferably, one end of the slide rod is provided with an auxiliary groove, and a second guide rail is provided inside the auxiliary groove. A first guide block is slidably connected inside the second guide rail. A positioning block is engaged on one side of the first guide block. A motor is built into the positioning block. A connecting electric push rod is fixedly connected to the upper surface of the positioning block. A cutting wheel is fixedly connected to the output end of the connecting motor. The cutting wheel is located on one side of the positioning block and can slide inside the second guide rail.

[0012] Preferably, a storage tank is fixed to the upper surface of the slide bar, the storage tank stores cutting fluid, and the slide bar has several spray holes at the position corresponding to the cutting wheel, the spray holes spray out cutting fluid to assist the cutting wheel in cutting.

[0013] Preferably, the collecting assembly further includes a horizontal plate fixed to one side of the first guide rail, a winding box fixed to the upper surface of the horizontal plate, a fixed motor fixed to one side of the winding box, a positioning roller fixed to the output end of the fixed motor, a connecting plate and a baffle fixed to the circumferential surface of the positioning tube, the connecting plate being lower than the baffle, a magnetic plate fixed to the bottom end of the connecting plate and the baffle, a fixing block fixed to the circumferential surface of the winding box, a rotating shaft fixed to the lower surface of the fixing block, rotating covers rotatably connected to both ends of the rotating shaft, and a guide groove provided at the contact point between the winding box and the horizontal plate, the guide groove being used to guide the extended portion of the cut steel plate.

[0014] Preferably, after the steel ingot is fed into the mill inlet via a conveyor chain, it is rolled into a steel plate by several rolls. During the rolling process, two first hydraulic cylinders on one side of the fixed plate are activated. The two first hydraulic cylinders drive the push plate fixed to their output ends. The push plate pushes the steel plate to the limit plate on the other side, so that one side of the steel plate abuts against the limit plate. During the process of the push plate pushing the steel plate, the difference between the actual width and the standard width of the steel plate segment is measured. Specifically, during the push plate pushing process, the first rack plate is pulled. The first rack plate drives the gear to rotate between the support plates. The rotation of the gear drives the second rack plate to move in the opposite direction. The second rack plate drives the measuring head to move. The second rack plate slides under the limit of the auxiliary plate. When the width of the steel plate segment is greater than the standard, the distance between the measuring head and the fixed plate is greater than the standard distance, and the distance difference is measured. After the measurement is completed, the collection component is activated to cut and collect the extended part of the steel plate segment.

[0015] Preferably, after the distance measurement is completed, the first guide rail on one side of the fixed plate is activated, and the slide rod inside the first guide rail slides along the first guide groove. During the sliding process, the slide rod drives the cutting wheel at one end to approach the steel plate, so that the auxiliary groove at one end of the slide rod is inserted into the steel plate. During the insertion process, the initial position of the cutting wheel is higher than the steel plate. After the steel plate is inserted, the second guide rail is activated to drive the first guide block to slide along the second guide rail and adjust the position. According to the distance difference measured by the distance measuring head, the cutting wheel is driven to be directly above the section of the steel plate. Then, the connecting electric push rod is activated to drive the positioning block to slide down a certain distance in the first guide block. At this time, the motor built into the positioning block has been started, driving the cutting wheel to perform the cutting work.

[0016] Preferably, the cut steel plate moves along the horizontal plate to the guide groove in the winding box and slides along the inner wall of the winding drum. During the sliding process, after the steel plate moves to the top, it is blocked by the baffle and then guided by the connecting plate. The steel plate is inserted between the connecting plate and the baffle until it is magnetically attracted to the magnetic plate at the bottom of the connecting plate. Then the connecting plate and the baffle retract. Both the connecting plate and the baffle are telescopic plates. Then the fixed motor on one side of the winding box is started. The fixed motor drives the positioning roller to rotate. The positioning roller drives the connecting plate and the baffle. The steel plate held by the connecting plate and the baffle will be wound up. After the winding is completed, the rotating cover on one side of the winding box is rotated. After the rotating cover is opened, the cut steel coil is taken out, and the rolling work is completed.

[0017] The beneficial effects of this invention are as follows: 1. The galvanized strip steel rolling device for cable tray production described in this invention starts the first guide rail after distance measurement, and the slide rod drives the cutting wheel to smoothly approach the steel plate. The auxiliary groove inserts into the steel plate to provide positioning for cutting and ensure accurate starting position of cutting. The position of the first guide block is adjusted by the second guide rail, so that the cutting wheel can be accurately positioned directly above the steel plate according to the distance difference, which can adapt to the cutting requirements of different width deviations. Finally, the electric push rod drives the positioning block to slide down, and the built-in motor starts the cutting wheel to cut. The whole process is highly automated and precise, effectively improving cutting accuracy, ensuring the quality of steel plate cutting, reducing scrap rate, and improving production efficiency and benefits.

[0018] 2. The galvanized strip steel rolling device for cable tray production described in this invention involves the cut steel plate moving to the guide groove of the winding box via a horizontal plate, sliding along the inner wall of the winding drum and being blocked by a baffle. After being guided by a connecting plate, it is magnetically attracted to a magnetic plate to achieve positioning and stable fixation. The connecting plate and the baffle are retractable to facilitate smooth winding of the steel plate. The starting fixed motor drives the positioning roller to efficiently complete the winding of the steel plate. After winding, the rotating cover can be opened for easy removal of the steel coil. The entire process is highly automated, with orderly winding, improving production efficiency, ensuring product quality, and reducing the difficulty and cost of manual operation.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 8 As shown in the embodiment of the present invention, a galvanized strip steel rolling device for cable tray production includes a plurality of rollers 11 arranged above the machine body 1. A common fixing plate 2 is fitted around the circumference of each roller 11. The fixing plate 2 is fixedly connected to the machine body 1. A limit plate 231 is provided on one side of the machine body 1 corresponding to the position of the fixing plate 2. A processing component is provided on the upper surface of the fixing plate 2. The processing component includes two first hydraulic cylinders 21 fixedly connected to one side of the fixing plate 2. A common push plate 22 is fixedly connected to the output end of the two first hydraulic cylinders 21. The push plate 22 is used to push the rolled steel plate. The upper surface of the fixing plate 2 is also provided with… The ranging component is used to measure the length of the extended portion of the rolled steel plate; a collecting component is provided on the upper surface of the fixed plate 2, which is used to collect the extended portion of the cut steel plate; the ranging component includes two support plates 25 fixed to the upper surface of the fixed plate 2, a gear 26 rotatably connected between the two support plates 25, a first rack plate 27 fixed to one side of the push plate 22, the first rack plate 27 penetrating the fixed plate 2, an auxiliary plate 28 fixed to one side of the fixed plate 2, a second rack plate 29 slidably connected to the lower surface of the auxiliary plate 28, and a ranging head 210 fixed to the upper surface of the second rack plate 29.

[0023] Specifically, in the actual use of existing galvanized strip steel rolling equipment for cable tray production, the mechanical vibration during equipment operation is difficult to completely eliminate. This vibration is transmitted to the steel plate being rolled. When the steel plate is continuously squeezed and deformed by the rolls 11, the vibration causes uneven local stress, resulting in abnormal expansion of some steel plates in the width direction. As a result, the width of some areas of the rolled steel plate exceeds the standard range. In the subsequent coiling process, these steel plates with excessive width cannot be flat and attached to other parts, resulting in local bulges, wrinkles or misalignment on the surface of the coiled steel. This not only reduces the overall appearance quality of the coiled steel, but also causes fluctuations in coiling tension, causing the core to loosen or even collapse. This can lead to equipment jamming, shutdown for maintenance, and reduced production efficiency and product qualification rate. Therefore, the present invention solves the above problems by setting the above structure. First, after the steel ingot is fed into the mill inlet by the conveyor chain, it is rolled into a steel plate by several rolls 11. During the rolling process, two first hydraulic cylinders 21 on one side of the fixed plate 2 are activated. The two first hydraulic cylinders 21 drive the push plate 22 fixed to their output ends. The push plate 22 pushes the steel plate to the limiting plate 231 on the other side, so that one side of the steel plate abuts against the limiting plate 231. During the process of the push plate 22 pushing the steel plate, the difference between the actual width and the standard width of the steel plate segment is measured. Specifically, the push plate 22... During the pushing process, the first rack plate 27 is pulled, and the first rack plate 27 drives the gear 26 to rotate between the support plates 25. The rotation of the gear 26 drives the second rack plate 29 to move in the opposite direction. The second rack plate 29 drives the measuring head 210 to move. The second rack plate 29 slides under the limit of the auxiliary plate 28. When the width of this section of steel plate is greater than the standard, the distance between the measuring head 210 and the fixed plate 2 is greater than the standard distance, and the distance difference is measured. After the measurement is completed, the collection component is started to cut and collect the extended part of the steel plate. By activating the first hydraulic cylinder 21 to drive the push plate 22, the steel plate can be pushed to the limit plate 231 for positioning. At the same time, by utilizing the linkage of the first rack plate 27, the gear 26, and the second rack plate 29, the measuring head 210 is moved to measure the difference between the actual width and the standard width of the steel plate. Once the width exceeds the standard, the collection component can be activated to cut and collect the extended part. The whole process is highly automated, effectively ensuring the quality of the steel plate width, reducing manual intervention, improving production efficiency and product qualification rate, and reducing production costs.

[0024] like Figure 3 As shown, in this embodiment, a fixing groove 23 is provided on one side of the push plate 22, and a number of rotating wheels 24 are rotatably connected in the fixing groove 23. The rotating wheels 24 are used to assist the movement of the rolled steel plate.

[0025] Specifically, by rotating a number of rollers 24 on one side of the push plate 22, the rollers 24 can reduce friction with the end of the steel plate during the alignment and positioning process, without affecting the normal movement of the steel plate.

[0026] Example 2: Figures 1 to 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the collecting component includes a first guide rail 211 fixed to one side of the fixed plate 2, a first guide groove 216 is provided in the first guide rail 211, a slide rod 217 is slidably connected in the first guide groove 216, a cutting wheel 223 is rotatably arranged inside the slide rod 217, the cutting wheel 223 is used to cut the extended part of the steel plate; an auxiliary groove 218 is provided at one end of the slide rod 217, a second guide rail 219 is provided inside the auxiliary groove 218, a first guide block 220 is slidably connected in the second guide rail 219, a positioning block 221 is snapped into one side of the first guide block 220, a motor is built into the positioning block 221, a connecting electric push rod 222 is fixedly connected to the upper surface of the positioning block 221, a cutting wheel 223 is fixedly connected to the output end of the connecting motor, the cutting wheel 223 is located on one side of the positioning block 221, and the cutting wheel 223 can slide in the second guide rail 219; Specifically, after the distance measurement is completed, the first guide rail 211 on one side of the fixed plate 2 is activated. The slide rod 217 in the first guide rail 211 will slide along the first guide groove 216. During the sliding process, the slide rod 217 drives the cutting wheel 223 set at one end to approach the steel plate, so that the auxiliary groove 218 opened at one end of the slide rod 217 is inserted into the steel plate. During the insertion process, the initial position of the cutting wheel 223 is higher than the steel plate. After the steel plate is inserted, the second guide rail 219 is activated to drive the first guide block 220 to slide along the second guide rail 219 and adjust the position. According to the distance difference measured by the distance measuring head 210, the cutting wheel 223 is driven to be directly above the section of steel plate. Then the connecting electric push rod 222 is activated to drive the positioning block 221 to slide down a certain distance in the first guide block 220. At this time, the motor built into the positioning block 221 has been started, driving the cutting wheel 223 to perform cutting work. After distance measurement is completed, the first guide rail 211 is activated, and the slide bar 217 drives the cutting wheel 223 to smoothly approach the steel plate. The auxiliary groove 218 inserts into the steel plate to provide positioning for cutting and ensures accurate starting position of cutting. The position of the first guide block 220 is adjusted by the second guide rail 219, so that the cutting wheel 223 can be precisely positioned above the steel plate according to the distance difference, which can adapt to the cutting requirements of different width deviations. Finally, the electric push rod 222 is connected to drive the positioning block 221 to slide down, and the built-in motor starts the cutting wheel 223 to cut. The whole process is highly automated and precise, effectively improving cutting accuracy, ensuring steel plate cutting quality, reducing scrap rate, and improving production efficiency and benefits.

[0027] like Figure 8As shown, the collecting assembly in this embodiment also includes a horizontal plate 212 fixed to one side of the first guide rail 211. A winding box 213 is fixed to the upper surface of the horizontal plate 212. A fixed motor 214 is fixed to one side of the winding box 213. A positioning roller 224 is fixed to the output end of the fixed motor 214. A connecting plate 225 and a baffle 226 are fixed to the circumferential surface of the positioning tube. The height of the connecting plate 225 is lower than that of the baffle 226. A magnetic plate is fixed to the bottom end of the connecting plate 225 and the baffle 226. A fixing block 227 is fixed to the circumferential surface of the winding box 213. A rotating shaft 228 is fixed to the lower surface of the fixing block 227. A rotating cover 215 is rotatably connected to both ends of the rotating shaft 228. A guide groove 232 is provided at the contact point between the winding box 213 and the horizontal plate 212. The guide groove 232 is used to guide the extended part of the cut steel plate.

[0028] Specifically, the cut steel plate moves along the horizontal plate 212 to the guide groove 232 opened in the winding box 213, and slides along the inner wall of the winding drum. During the sliding process, after the steel plate moves to the top, it is blocked by the baffle 226, and then guided by the connecting plate 225. The steel plate is inserted between the connecting plate 225 and the baffle 226 until it is magnetically attracted to the magnetic plate at the bottom of the connecting plate 225. Then the connecting plate 225 and the baffle 226 retract. Both the connecting plate 225 and the baffle 226 are telescopic plates. Then the fixed motor 214 on one side of the winding box 213 is started. The fixed motor 214 drives the positioning roller 224 to rotate. The positioning roller 224 drives the connecting plate 225 and the baffle 226. The steel plate held by the connecting plate 225 and the baffle 226 will be wound up. After the winding is completed, the rotating cover 215 on one side of the winding box 213 is rotated. After the rotating cover 215 is opened, the cut steel coil is taken out, and the rolling work is completed. After cutting, the steel plate can be moved to the guide groove 232 of the winding box 213 by means of the horizontal plate 212. It slides along the inner wall of the winding drum and is blocked by the baffle 226. After being guided by the connecting plate 225, it is magnetically attracted to the magnetic plate to achieve positioning and stable fixation. The connecting plate 225 and the baffle 226 can be retracted to facilitate the smooth winding of the steel plate. The starting fixed motor 214 drives the positioning roller 224 to efficiently complete the winding of the steel plate. After winding, the rotating cover 215 can be opened to facilitate the removal of the steel coil. The whole process is highly automated, the winding is orderly, which improves production efficiency, ensures product quality, and reduces the difficulty and cost of manual operation.

[0029] Working principle: First, after the steel ingot is fed into the mill inlet via the conveyor chain, it is rolled into a steel plate by several rolls 11. During the rolling process, two first hydraulic cylinders 21 on one side of the fixed plate 2 are activated. The two first hydraulic cylinders 21 drive the push plate 22 fixed to their output ends. The push plate 22 pushes the steel plate to the limit plate 231 on the other side, so that one side of the steel plate abuts against the limit plate 231. During the process of the push plate 22 pushing the steel plate, the difference between the actual width and the standard width of the steel plate segment is measured. Specifically, the push plate 22 pulls during the pushing process. The first rack plate 27 drives the gear 26 to rotate between the support plates 25. The rotation of the gear 26 drives the second rack plate 29 to move in the opposite direction. The second rack plate 29 drives the measuring head 210 to move. The second rack plate 29 slides under the limit of the auxiliary plate 28. When the width of this section of steel plate is greater than the standard, the distance between the measuring head 210 and the fixed plate 2 is greater than the standard distance, and the distance difference is measured. After the measurement is completed, the collection component is started to cut and collect the extended part of the section of steel plate. By activating the first hydraulic cylinder 21 to drive the push plate 22, the steel plate can be pushed to the limit plate 231 for positioning. At the same time, by utilizing the linkage of the first rack plate 27, gear 26, and second rack plate 29, the measuring head 210 is moved to measure the difference between the actual width and the standard width of the steel plate. Once the width exceeds the standard, the collection component can be activated to cut and collect the extended part. The whole process is highly automated, effectively ensuring the quality of the steel plate width, reducing manual intervention, improving production efficiency and product qualification rate, and reducing production costs. After the distance measurement is completed, the first guide rail 211 on one side of the fixed plate 2 is activated. The slide rod 217 in the first guide rail 211 will slide along the first guide groove 216. During the sliding process, the slide rod 217 drives the cutting wheel 223 set at one end to approach the steel plate, so that the auxiliary groove 218 opened at one end of the slide rod 217 is inserted into the steel plate. During the insertion process, the initial position of the cutting wheel 223 is higher than the steel plate. After the steel plate is inserted, the second guide rail 219 is activated to drive the first guide block 220 to slide along the second guide rail 219 and adjust the position. According to the distance difference measured by the distance measuring head 210, the cutting wheel 223 is driven to be directly above the section of steel plate. Then the connecting electric push rod 222 is activated to drive the positioning block 221 to slide down a certain distance in the first guide block 220. At this time, the motor built into the positioning block 221 has been started, driving the cutting wheel 223 to perform cutting work. After distance measurement is completed, the first guide rail 211 is activated, and the slide bar 217 drives the cutting wheel 223 to smoothly approach the steel plate. The auxiliary groove 218 inserts into the steel plate to provide positioning for cutting and ensures accurate starting position of cutting. The position of the first guide block 220 is adjusted by the second guide rail 219, so that the cutting wheel 223 can be precisely positioned above the steel plate according to the distance difference, which can adapt to the cutting requirements of different width deviations. Finally, the electric push rod 222 is connected to drive the positioning block 221 to slide down, and the built-in motor starts the cutting wheel 223 to cut. The whole process is highly automated and precise, effectively improving cutting accuracy, ensuring steel plate cutting quality, reducing scrap rate, and improving production efficiency and benefits. Finally, the cut steel plate moves along the horizontal plate 212 to the guide groove 232 opened in the winding box 213, and slides along the inner wall of the winding drum. During the sliding process, after the steel plate moves to the top, it is blocked by the baffle 226, and then guided by the connecting plate 225. The steel plate is inserted between the connecting plate 225 and the baffle 226 until it is magnetically attracted to the magnetic plate at the bottom of the connecting plate 225. Then the connecting plate 225 and the baffle 226 retract. The connecting plate 225 and the baffle 226 are both telescopic plates. Then the fixed motor 214 on one side of the winding box 213 is started. The fixed motor 214 drives the positioning roller 224 to rotate. The positioning roller 224 drives the connecting plate 225 and the baffle 226. The steel plate held by the connecting plate 225 and the baffle 226 will be wound up. After the winding is completed, the rotating cover 215 on one side of the winding box 213 is rotated. After opening the rotating cover 215, the cut steel coil is taken out, and the rolling work is completed. After cutting, the steel plate can be moved to the guide groove 232 of the winding box 213 by means of the horizontal plate 212. It slides along the inner wall of the winding drum and is blocked by the baffle 226. After being guided by the connecting plate 225, it is magnetically attracted to the magnetic plate to achieve positioning and stable fixation. The connecting plate 225 and the baffle 226 can be retracted to facilitate the smooth winding of the steel plate. The starting fixed motor 214 drives the positioning roller 224 to efficiently complete the winding of the steel plate. After winding, the rotating cover 215 can be opened to facilitate the removal of the steel coil. The whole process is highly automated, the winding is orderly, which improves production efficiency, ensures product quality, and reduces the difficulty and cost of manual operation.
