Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, specifically to a transport roller conveyor for rough-rolled strip steel processing. Background Technology

[0002] Strip steel is a narrow and long steel plate, also known as steel strip. It is a type of steel produced by steel rolling mills to meet the needs of industrialized production in different industrial sectors for various metal or mechanical products. It is a steel plate formed by multiple rolling processes from heated steel billets. The processing involves multiple rolling steps, including roughing, intermediate rolling, and finishing rolling. Roughing begins by side rolling the steel billet to obtain an intermediate billet with a consistent width and neat edges. Then, the intermediate rolling mill uses a rolling mill to adjust the size and thickness of the strip steel. Finally, finishing rolling further reduces the thickness of the strip steel and adjusts its dimensions to meet the specifications of the final product.

[0003] However, strip steel faces many problems during its transport after multiple rolling processes. After rough rolling, the strip becomes thinner and narrower, making it prone to sagging or edge deformation during subsequent transport. Furthermore, its larger surface area increases the likelihood of surface scratches during contact with the rollers. It is also more sensitive to changes in temperature and humidity; the strip surface may oxidize, and even stress deformation due to temperature fluctuations can affect further processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a transport roller conveyor for rough-rolled strip steel processing, which avoids the problems of scratches, oxidation, and contamination of the rough-rolled strip steel during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveyor roller conveyor for rough-rolled strip steel processing, comprising symmetrically arranged frames and roller conveyors arranged between the frames. The frames are arranged in three groups. A constant temperature shell that completely encloses the frames is arranged on the outer side of the frames. The constant temperature shell has conveying ports with heat insulation curtains at both ends. Multiple heat-spreading plates are evenly arranged on the top surface of the inner wall of the constant temperature shell. A first temperature sensor is arranged on the front and rear sides of the inner wall of the constant temperature shell. A return component is arranged in the middle of the inner side of each set of frames. A leveling component is arranged above the gap between each pair of adjacent sets of frames on the inner wall of the constant temperature shell.

[0006] Furthermore, smoothing components are also provided on the inner edges of the front and rear transport ports.

[0007] Furthermore, the return assembly includes return telescopic rods symmetrically arranged inside the frame, with the fixed end of the return telescopic rod fixed to the outside of the frame. A return plate is provided at the telescopic end of the return telescopic rod, and a detachable arc-shaped guide plate is connected to the return plate. The top surface of the arc-shaped guide plate is close to the upper surface of the roller conveyor.

[0008] Furthermore, the leveling component includes a placement plate spanning above the frame, with two leveling telescopic rods symmetrically arranged on the placement plate. A leveling arc plate with the same width as the roller conveyor is arranged between the leveling telescopic rods. A second temperature sensor is arranged in the middle of the leveling arc plate, and the detection end of the second temperature sensor extends to 2-3 mm above the lower surface of the leveling arc plate.

[0009] Furthermore, observation windows are provided on both sides of the upper end of the constant temperature shell.

[0010] Furthermore, the constant temperature shell has maintenance openings on both sides that fit against the outer side of the frame, and a telescopic support frame is provided on the bottom surface of the inner wall of the constant temperature shell. When the telescopic support frame is extended, it can abut against the bottom of the roller conveyor.

[0011] Furthermore, a maintenance opening is provided on the side of the constant temperature shell between the frame maintenance port and the observation window, and a sealing plate is rotatably connected to the outside of the maintenance opening.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting a fully enclosed constant-temperature shell outside the conveyor rollers, along with a heat spreader and a primary temperature sensor, the strip steel on the conveyor rollers can maintain a constant or uniform temperature, preventing oxidation or stress deformation of the strip steel. It can also prevent foreign matter from contaminating the strip steel. By setting a return component, the direction of the strip steel during transport can be guided, preventing hard collisions between the strip steel and the frame. By setting a leveling component, the strip steel during transport can be flattened, preventing bulging during return and ensuring the flatness of the strip steel during transport.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4 As shown, a conveyor roller conveyor for rough-rolled strip steel processing includes symmetrically arranged frames (1) and roller conveyors 2 arranged between the frames 1. The frames 1 are arranged in three groups. A constant temperature shell 3 that completely covers the frames 1 is arranged on the outside of the frames 1. The constant temperature shell 3 has a conveyor opening 301 with heat insulation curtain at both ends. Multiple heat-spreading plates 302 are evenly arranged on the top surface of the inner wall of the constant temperature shell 3. A first temperature sensor 303 is arranged on the front and back sides of the inner wall of the constant temperature shell 3. A positioning component 4 is arranged in the middle of the inner side of each set of frames 1. A leveling component 5 is arranged above the gap between each two adjacent sets of frames 1 on the inner wall of the constant temperature shell 3.

[0021] like Figure 1 As shown, the main improvement of this utility model lies in avoiding the problems of scratches, oxidation, and contamination of the strip steel after rough rolling during transportation. Figures 1 to 4 As shown, in the conveyor roller conveyor for rough-rolled strip steel processing of this utility model, during use, the heating plate 302 is first controlled according to the transportation requirements. With the cooperation of the first temperature sensor 303, the temperature inside the constant temperature shell 3 is adjusted to a suitable range. Then, the strip steel is introduced onto the roller conveyor 2 from the front end and allowed to move forward along the conveyor roller conveyor 2. During the forward movement, the arc-shaped guide plate 403 will clamp and guide the strip steel under the extension and retraction of the return telescopic rod 401, and the position of the strip steel will be corrected. At the same time, the flattening arc-shaped plate 503 will be flattened by the flattening telescopic rod. Driven by 502, it moves downwards and approaches the strip steel without contacting it, avoiding heat generation due to friction between the flat arc plate 503 and the strip steel. Simultaneously, it restricts the strip steel during transport, preventing bulging during repositioning and ensuring its flatness during transport. Meanwhile, the second temperature sensor 504 installed in the middle of the flat arc plate 503 will detect the temperature of the strip steel. Multiple sets of second temperature sensors 504 on the flattening components 5 will work together to monitor the temperature at different locations on the strip steel in real time, achieving real-time control of strip steel temperature changes.

[0022] like Figure 4 As shown, the front and rear transport ports 301 are also provided with flattening components 5 on their inner edges.

[0023] Specifically, by setting leveling components 5 at the front and rear transport ports 301, the strip steel is leveled before it is transported in and after it is transported out, preventing the strip steel from bulging.

[0024] like Figure 4 As shown, the return assembly 4 includes return telescopic rods 401 symmetrically arranged inside the frame 1. The fixed end of the return telescopic rod 401 is fixed to the outside of the frame 1. A return plate 402 is provided at the telescopic end of the return telescopic rod 401. A detachable arc-shaped guide plate 403 is connected to the return plate 402. The top surface of the arc-shaped guide plate 403 is close to the upper surface of the roller conveyor 2.

[0025] Specifically, as the return telescopic rod 401 extends and retracts, the return plate 402 will drive the arc-shaped guide plate 403 to move left and right, thereby pushing the two sides of the strip. Under the guidance of the arc-shaped guide plate 403, the position of the strip will be corrected, and at the same time, it can prevent the strip from having a hard collision with the frame.

[0026] like Figure 4 As shown, the leveling component 5 includes a placement plate 501 spanning above the frame 1. Two leveling telescopic rods 502 are symmetrically arranged on the bottom surface of the placement plate 501. A leveling arc plate 503 with the same width as the roller conveyor 2 is arranged between the bottom surfaces of the leveling telescopic rods 502. A second temperature sensor 504 is arranged in the middle of the leveling arc plate 503. The detection end of the second temperature sensor 504 extends to 2-3 mm above the lower surface of the leveling arc plate 503.

[0027] Specifically, by extending and retracting the flattening telescopic rod 502, the flattening arc plate 503 on the bottom surface of the placement plate 501 will move up and down. When the strip passes through the entire device, the flattening arc plate 503 moves downward and gets close to the strip without contacting it, so as to avoid the flattening arc plate 503 and the strip generating heat due to friction. At the same time, the second temperature sensor 504 set in the middle of the flattening arc plate 503 will detect the temperature of the strip. With the help of multiple sets of flattening components 5, the real-time control of the temperature change of the strip can be achieved.

[0028] like Figures 1 to 3 As shown, observation windows 304 are provided on both sides of the upper end of the constant temperature shell 3. This arrangement allows staff to observe the transportation of the strip steel.

[0029] like Figure 2 and Figure 3 As shown, the constant temperature shell 3 has maintenance openings 305 on both sides that fit against the outer side of the frame 1. The bottom surface of the inner wall of the constant temperature shell 3 is provided with a telescopic support frame 306, which can abut against the bottom of the roller conveyor 2 when extended.

[0030] Specifically, by setting up a frame maintenance port 305, the frame 1 can be disassembled from the slot of the frame maintenance port 305 when maintenance is required, so as to realize the maintenance of the device; at the same time, by setting up a telescopic support frame 306, the roller conveyor 2 can be supported when the frame 1 is maintained, so as to prevent the roller conveyor 2 from sagging and deforming due to the lack of support at one end. At the same time, when the roller conveyor 2 needs maintenance, it provides necessary support for the disassembly of the frame 1 at both ends, thereby improving work efficiency.

[0031] like Figures 1 to 3 As shown, a maintenance port 307 is provided on the side of the constant temperature shell 3 between the frame maintenance port 305 and the observation window 304, and a sealing plate 308 is rotatably connected to the outside of the maintenance port 307.

[0032] Specifically, by setting up maintenance port 307, staff can maintain the components of the device without disassembling the thermostatic shell 3. At the same time, when maintenance is not required, the shell 308 can be closed to ensure the integrity of the thermostatic shell 3.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
