Description

Technical Field

[0001] This utility model relates to the technical field of cold-rolled steel, specifically to a roller rotation alignment device. Background Technology

[0002] Cold-rolled steel is steel produced through cold rolling. Cold rolling involves further thinning No. 1 steel sheet to the target thickness at room temperature. Compared to hot-rolled steel sheet, cold-rolled steel sheet has more precise thickness, a smoother and more attractive surface, and various superior mechanical properties, especially in terms of machinability. Because cold-rolled coils are relatively brittle and hard, making them less suitable for processing, cold-rolled steel sheet typically requires annealing, pickling, and surface leveling.

[0003] When steel is conveyed on the conveyor rollers, the driving force that propels the steel forward is the friction between the drive roller and the steel. During the installation and use of the conveyor rollers, some of the conveyor rollers may partially contact the strip steel without fully adhering to it. The surface contact condition is difficult to identify with the naked eye, which is not conducive to subsequent alignment and adjustment operations. Utility Model Content

[0004] The purpose of this invention is to provide a roller rotation alignment device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The system includes a support frame, on which a drive roller and a transport roller with roller shafts are fixedly and rotatably mounted. Adjustment plates for controlling the height of the transport roller are fixedly mounted at both ends of the transport roller. A mounting bracket is fixedly mounted on the top wall of each adjustment plate. An electric brush aligned with the transport roller is obliquely mounted on the mounting bracket. The brush bristles are made of metal and are connected to an external power source. An insulating and wear-resistant layer is wrapped around the surface of the transport roller. Several sets of detection cables are embedded in the insulating and wear-resistant layer. The detection cables are staggered and have detection resistors fixedly mounted on them. The detection cables are electrically connected to the transport roller shaft, which is electrically connected to a microcontroller. An external indicator light is connected to the microcontroller and is fixedly mounted on the outer wall of the support frame, its position corresponding to the detection cables.

[0007] By adopting the above technical solution, during use, the drive roller drives the strip forward. During the forward movement of the strip, it is smoothly transferred by the rotation of the transport roller. During strip transport, the metal bristles of the brush are connected to an external power source while simultaneously providing an electrical signal input by contacting the strip surface. The strip passes over the surface of the transport roller during transport. In each set of detection cables, one cable end is flush with the outer edge of the insulating wear-resistant layer. Therefore, when the transport roller is fully in contact with the strip, the detection cable can receive a detection signal. Because the detection cables are staggered, only one detection cable is connected at a time. The electrical signal is then transported by the roller shaft through the microcontroller. Since each detection cable is equipped with a detection... The resistance is measured, so the current magnitude of the detected electrical signal will vary. The microcontroller distinguishes the current magnitude of the detected electrical signal to detect which specific detection cable is successfully energized. This indicates that the surface of the transport roller at this point is perfectly in contact with the strip. Conversely, if no electrical signal passes through this point, it means that the strip is not fully in contact. The microcontroller selectively controls the flashing of the indicator light based on the input electrical signal. If no electrical signal is received in a certain area within several rotation cycles, it means that the strip is not in contact at this point, and the indicator light flashes. Therefore, controlling the height of the adjustment plate can adjust the contact degree between the transport roller and the strip surface, which facilitates the subsequent alignment and bonding operation of the transport roller.

[0008] Furthermore, the bracket has adjustment slots on both sides for adjusting the height. The adjustment plate is slidably engaged in the adjustment slots. The adjustment plate is threadedly connected to a lifting bolt. One end of the lifting bolt is rotatably connected to the bracket. A tightening nut is fixedly installed on the outer edge of the lifting bolt. A pair of clamping plates are extended from the side of the adjustment plate near the conveyor roller. A rotating shaft is fixed between the clamping plates. A connecting block is rotatably mounted on the rotating shaft. A sliding groove is opened on one side of the bracket clamping plate for the rotating shaft to slide laterally. A rotating bearing is fitted into the side of the connecting block near the conveyor roller. The conveyor roller shaft is embedded in the rotating bearing.

[0009] By adopting the above technical solution, during use, a wrench is used to turn and tighten the nut, thereby driving the lifting bolt to rotate. When the lifting bolt rotates, the adjusting plate rises or falls under the action of the threaded engagement. The rotating shaft engages with the connecting block, allowing the operator to freely adjust the height of the adjusting plates on both sides to adjust the angle of the conveyor roller without obstructing the circuit connection. When the angle between the conveyor roller and the support changes, the connecting block rotates adaptively relative to the rotating shaft to adjust the angle. At the same time, the rotating shaft on one side adaptively displaces relative to the chute. The conveyor roller can be freely adjusted within a certain angle range to align with the surface of the strip steel.

[0010] Furthermore, the detection cable includes a first cable, a second cable, a third cable, and a fourth cable. The first cable is flush with the outer edge of the insulating and wear-resistant layer. The lengths of the second, third, and fourth cables decrease sequentially. The second, third, and fourth cables are embedded inside the transport roller.

[0011] By adopting the above technical solution, the first cable is flush with the outer edge of the insulating wear-resistant layer, used to detect whether the surface of the insulating wear-resistant layer, i.e., the conveyor roller, is flush with the strip steel. The lengths of the second, third, and fourth cables are successively shortened, thus being embedded in the insulating wear-resistant layer. When the insulating wear-resistant layer wears, the second, third, and fourth cables will be exposed in sequence. Because the exposed cables have different detection resistances, the microcontroller can analyze the different wear levels at different positions on the conveyor roller based on the received electrical signals. Furthermore, based on the different wear levels, it can select different colors to control the indicator lights to flash. For example, when the signal of the first cable is detected... A flashing green indicator light corresponding to a given location indicates that the conveyor roller is operating normally. Simultaneous detection of signals from the first and second cables indicates slight wear in that area of ​​the conveyor roller, and the indicator light flashes blue. Simultaneous detection of signals from the first, second, and third cables indicates moderate wear in that area, and the indicator light flashes yellow. Simultaneous detection of signals from the first, second, third, and fourth cables indicates severe wear in that area, and the indicator light flashes red. Users can monitor the wear level of different areas of different conveyor rollers in real time based on the indicator light colors, facilitating future maintenance.

[0012] In summary, the beneficial technical effects of this utility model are as follows:

[0013] 1. It adopts an adjustment plate, brush, insulating wear-resistant layer, detection cable, detection resistor, microcontroller and signal light. When the electrical signal is not received in a certain area within several rotation cycles, it means that the area is not in contact with the strip steel, and the signal light in that area flashes. Therefore, controlling the height of the adjustment plate can adjust the contact degree between the conveyor roller and the surface of the strip steel, thereby facilitating the subsequent alignment and bonding operation of the conveyor roller.

[0014] 2. It adopts adjustment, adjustment, lifting screw, tightening nut, clamp plate, rotating shaft, connecting block and slide. The connecting block adaptively rotates and adjusts the angle relative to the rotating shaft. At the same time, the rotating shaft on one side adaptively displaces relative to the slide. The conveyor roller can be freely adjusted within a certain angle range to align with the surface of the strip steel.

[0015] 3. The system employs a first cable, a second cable, a third cable, and a fourth cable, which allows users to monitor the wear level of different areas of different conveyor rollers in real time based on the color of the signal lights, facilitating subsequent maintenance.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 The present invention provides the following technical solution:

[0025] The system includes a bracket 1, with a drive roller 2 and a transport roller 3 fixedly and rotatably mounted between the brackets 1. Adjustment plates 4, each controlling the height of the transport roller 3, are fixedly mounted at both ends of the transport roller 3. A mounting frame 5 is fixedly mounted on the top wall of the adjustment plate 4. An electric brush 51, aligned with the transport roller 3, is obliquely mounted on the mounting frame 5. The brush bristles 52 of the electric brush 51 are made of metal and are connected to an external power source. An insulating and wear-resistant layer 31 covers the surface of the transport roller 3. Several sets of detection cables 6 are embedded in the insulating and wear-resistant layer 31, and the detection cables 6 are staggered and fixed. A detection resistor 61 is fixedly installed, and a detection cable 6 is electrically connected to the shaft of a transport roller 3. The shaft of the transport roller 3 is electrically connected to a microcontroller 62. The microcontroller 62 is equipped with an externally connected signal light 63, which is fixedly installed on the outer wall of the bracket 1 and its position corresponds to the detection cable 6. In use, the drive roller 2 drives the strip forward. During the forward movement of the strip, it is smoothly transferred by the rotation of the transport roller 3. During the transport of the strip, the metal bristles 52 of the brush 51 are connected to an external power source, and the bristles 52 contact the surface of the strip to provide an electrical signal input. The strip is then transported... During the process, the strip will pass over the surface of the conveyor roller 3. One cable end in each set of detection cables 6 is flush with the outer edge of the insulating wear-resistant layer 31. Therefore, when the conveyor roller 3 is fully in contact with the strip, the detection cable 6 can receive a detection signal. Because the detection cables 6 are staggered, only one detection cable 6 is connected at a time. The signal is then transported by the roller shaft to the microcontroller 62. Since each detection cable 6 has a detection resistor 61 installed, the current magnitude of the detection signal will differ. The microcontroller 62 distinguishes the current magnitude of the detection signal from... If a specific detection cable 6 is successfully energized, it indicates that the surface of the transport roller 3 is perfectly bonded to the strip. Conversely, if no electrical signal passes through a certain area, it means that the strip is not fully bonded. The microcontroller 62 selectively controls the indicator light 63 to flash based on the input electrical signal. If no electrical signal is received in a certain area within several rotation cycles, it means that the strip is not bonded to that area, and the indicator light 63 will flash. Therefore, the height of the adjustment plate 4 is controlled to adjust the bonding degree between the transport roller 3 and the strip surface, which facilitates the subsequent alignment and bonding operation of the transport roller 3.

[0026] The support frame 1 has adjustment slots 41 on both sides for adjusting the height. Adjustment plate 4 is slidably engaged in the adjustment slots 41. Adjustment plate 4 is threadedly connected to lifting bolts 42, one end of which is rotatably connected to the support frame 1. A tightening nut 43 is fixed to the outer edge of the lifting bolt 42. A pair of clamping plates 44 extend from the side of the adjustment plate 4 near the conveyor roller 3. A rotating shaft 45 is fixed between the clamping plates 44. A connecting block 46 is rotatably mounted on the rotating shaft 45. A sliding groove 47 is provided on one side of the clamping plate 44 of the support frame 1 for the lateral sliding of the rotating shaft 45. A rotating bearing 48 is fitted onto the side of the connecting block 46 near the conveyor roller 3, and the roller shaft of the conveyor roller 3 is embedded in the rotating bearing 48. The moving bearing 48 is installed. In use, the nut 43 is turned with a wrench, which drives the lifting bolt 42 to rotate. When the lifting bolt 42 rotates, the adjusting plate 4 rises or falls under the action of the threaded engagement. The rotating shaft 45 cooperates with the connecting block 46. Without hindering the circuit connection, the operator can freely adjust the height of the adjusting plates 4 on both sides to adjust the angle of the conveyor roller 3. When the angle between the conveyor roller 3 and the bracket 1 changes, the connecting block 46 rotates adaptively relative to the rotating shaft 45 to adjust the angle. At the same time, the rotating shaft 45 on one side adaptively displaces relative to the slide 47. The conveyor roller 3 can be freely adjusted within a certain angle range to align with the surface of the strip steel.

[0027] The detection cable 6 includes a first cable 71, a second cable 72, a third cable 73, and a fourth cable 74. The first cable 71 is flush with the outer edge of the insulating wear-resistant layer 31. The lengths of the second, third, and fourth cables 72, 73, and 74 decrease sequentially. These cables are embedded inside the transport roller 3. The first cable 71, flush with the outer edge of the insulating wear-resistant layer 31, is used to detect whether the surface of the insulating wear-resistant layer 31, i.e., the transport roller 3, is flush with the strip steel. The second, third, and fourth cables 74, being sequentially shorter and thus embedded within the insulating wear-resistant layer 31, will expose the second, third, and fourth cables 72 in sequence when the insulating wear-resistant layer 31 wears down. Since the exposed cables have different detection resistances 61, the microcontroller 62 can analyze the different electrical signals received to determine whether the transport roller 3... The degree of wear at different locations is determined by the color of the control indicator 63. For example, when the signal of the first cable 71 is detected, the indicator 63 corresponding to that location flashes green, indicating that the conveyor roller 3 is operating normally. When the signals of the first cable 71 and the second cable 72 are detected simultaneously, it indicates that there is slight wear in this area of ​​the conveyor roller 3, and the indicator 63 flashes blue. When the signals of the first cable 71, the second cable 72, and the third cable 73 are detected simultaneously, it indicates that there is moderate wear in this area of ​​the conveyor roller 3, and the indicator 63 flashes yellow. When the signals of the first cable 71, the second cable 72, the third cable 73, and the fourth cable 74 are detected simultaneously, it indicates that there is severe wear in this area of ​​the conveyor roller 3, and the indicator 63 flashes red. Users can monitor the degree of wear in different areas of the conveyor roller 3 in real time according to the color of the indicator 63, which facilitates later maintenance.
