Description

Technical Field

[0001] The invention relates to the technical field of steel strip grinding, in particular to a cold-rolled steel strip grinding device with a dust removal function. Background Art

[0002] During the processing of cold-rolled steel strip, the surface quality has a crucial impact on its subsequent processing and performance. In order to remove the excess amount on the edge due to cold rolling and improve the appearance quality of the product, grinding is an indispensable process.

[0003] In the process of grinding the cold-rolled steel strip, conventional grinding devices are fixed grinding. It is impossible to flexibly change the extra amount of the cold-rolled steel strip edge, and the grinding time is fixed. Therefore, there may be problems such as uneven grinding, low grinding efficiency, and unstable grinding quality during the grinding process. If the extra amount on the edge cannot be completely ground, it may cause inconsistent grinding degrees on the two edges, and one side may be normal and the other side may have excess material, causing the cold-rolled steel strip to deflect, or both sides are not completely ground, and it may get stuck during the subsequent winding process. Summary of the invention

[0004] The purpose of the present invention is to provide a cold-rolled steel strip grinding device with a dust removal function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0007] In the grinding equipment, the equipment is provided with two, which are respectively placed on both sides of the cold-rolled steel strip. The equipment is used to grind the edge of the steel strip after the cold rolling is completed. The main mechanism provides a place for grinding, the conveying mechanism conveys the cold-rolled steel strip, and the steel strip detection mechanism is used to detect the edge of the cold-rolled steel strip to detect the excess amount compared with the normal position. The grinding mechanism is used to grind the excess amount of the edge of the steel strip. The edge of the cold-rolled steel strip is made smooth by grinding to prevent the cold-rolled steel strip from being rolled out due to the excess amount on the edge after grinding and rolling. There is a problem. At the same time, during the winding process, if there is excess material on the edge, since the edges on both sides are not consistent, one side may be normal and the other side may have excess material. If the excess amount is not ground off by grinding, the cold-rolled steel strip will deflect and will not be subjected to only radial force. The grinding adjustment mechanism is used to adjust the grinding angle. By driving the angle of the grinding device and the cold-rolled steel strip, the two are made vertically or parallel to grind the cold-rolled steel strip. The dust removal mechanism is used to remove the ground material to prevent it from falling on the cold-rolled steel strip and affecting the grinding and subsequent winding.

[0008] Furthermore, the main mechanism includes a grinding shell and a mounting base plate. The grinding shell and the mounting base plate are fastened together. A grinding cavity is arranged in the grinding shell. An inlet and an outlet are arranged on the grinding shell. The grinding shell is connected to a conveying mechanism, the mounting base plate is connected to the conveying mechanism, the grinding shell is connected to a steel belt detection mechanism, the grinding shell is connected to a grinding mechanism, the grinding shell is connected to a grinding adjustment mechanism, the grinding shell is connected to a dust removal mechanism, the grinding cavity is connected to a conveying mechanism, the grinding cavity is connected to a steel belt detection mechanism, the grinding cavity is connected to a grinding mechanism, the grinding cavity is connected to a grinding adjustment mechanism, and the grinding cavity is connected to a dust removal mechanism.

[0009] In the main mechanism, this mechanism is used to provide support and grinding space for the grinding device. The installation base plate is used to place the grinding shell and other mechanisms. In the grinding shell, there is also a grinding cavity. The grinding cavity is the specific place where the grinding device works. The cold-rolled steel strip enters the grinding cavity through the feed port, passes through the discharge port after grinding, and is then rolled up.

[0010] Furthermore, the transmission mechanism includes a first drive motor, a winding roller, a support shaft and a first support plate. The first support plate is placed in the grinding chamber, the first support plate is tightly connected to the wall of the grinding chamber, the winding roller and the support shaft are rotatably connected, the end of the support shaft away from the winding roller is tightly connected to the mounting base plate, the output end of the first drive motor is tightly connected to the winding roller, the fixed end of the first drive motor is tightly connected to the support shaft, there is one winding roller, a cold-rolled steel strip is wound on the winding roller, and the first support plate is connected to the steel strip detection mechanism.

[0011] In the transmission mechanism, the mechanism is used to transmit the cold-rolled steel strip, and the first driving motor is used to drive the winding roller to rotate to wind the cold-rolled steel strip. The winding roller is fixedly connected to the first section of the cold-rolled steel strip, and the cold-rolled steel strip is wound by the motor driving rotation. During the winding process, the cold-rolled steel strip is in a tensioned state, and the unwound part is basically parallel to the ground. The supporting shaft is used to support the winding roller to raise its position for easy winding. The first supporting plate is placed under the cold-rolled steel strip, and its width is smaller than the cold-rolled steel strip. It is used to install other mechanisms. After the device is started, the beginning of the cold-rolled steel strip after cold rolling is tightly connected to the winding roller, and the first driving motor is started to drive the winding roller to rotate to wind the cold-rolled steel strip. The winding roller is placed outside the grinding shell and will not be wound until the cold-rolled steel strip is ground. During the winding process, the cold-rolled steel strip is always in a tensioned state, and finally the grinding operation and winding can be better performed.

[0012] Furthermore, the steel strip detection mechanism includes a detection electric needle, a fixed bracket and a movable bracket. The steel strip detection mechanism is placed in the grinding chamber. There are four detection electric needles, which are divided into two groups. The first group of detection electric needles is connected to the fixed bracket, and the second group of detection electric needles is connected to the movable bracket. One end of the fixed bracket is tightly connected to the side wall of the first support plate, and the other two ends of the fixed bracket are tightly connected to the two detection electric needles of the first group respectively. The movable bracket is tightly connected to the two detection electric needles of the second group respectively. The needle tips of the same group of detection electric needles are relatively facing the cold-rolled steel strip. The two groups of detection electric needles The needle is placed on the edge of the cold-rolled steel strip, and the distance between two detection electric needles in the same group is the thickness of one cold-rolled steel strip. The steel strip detection mechanism also includes a rotating rod, a driven block and a second drive motor. The fixed end of the second drive motor is tightly connected to the wall of the grinding chamber, the output end of the second drive motor is tightly connected to the rotating rod, and the end of the rotating rod away from the second drive motor is rotatably connected to the inner wall of the grinding chamber. The rotating rod is provided with a thread, the driven block is provided with a circular through hole, and the circular through hole of the driven block is provided with a thread. The rotating rod and the driven block are connected by threads, and the driven block is tightly connected to one end of the movable bracket.

[0013] In the steel strip detection mechanism, the mechanism is used to detect the specific amount of excess material at the edge of the cold-rolled steel strip. The detection electric needle is used for detection. There are four detection electric needles, which are divided into two groups. The first group of detection electric needles is tightly connected to the fixed bracket, and the needle tips are opposite to each other. The distance is the thickness of a cold-rolled steel strip. The first group of detection electric needles is attached to the edge of the cold-rolled steel strip at the normal edge, but the two detection electric needles are not conductive with the cold-rolled steel strip at the normal edge. The fixed bracket is tightly connected to the first support plate, so that the fixed bracket and the first group of detection electric needles are fixed. The fixed end of the second drive motor is tightly connected to the inner wall of the grinding chamber, and the output end is tightly connected to the rotating rod. A driven block is threadedly connected to the rotating rod, and the driven block is tightly connected to the moving bracket. After the second drive motor is started, the rotating rod will rotate under the action of the second drive motor, and the rotating rod and the driven block are threadedly connected, so the driven block will move along the direction of the rotating rod, so as to control the movement of the moving bracket. The two detection electric needles of the second group are tightly connected to the moving bracket, and the detection electric needles of the second group and the detection electric needles of the first group are in the same straight line parallel to the rotating rod. In this way, the excess amount of the edge of the cold-rolled steel strip can be measured. The first group of detection electric needles and the second group of detection electric needles are fitted together to make the distance between the two groups of detection electric needles as small as possible. When the cold-rolled steel strip with no excess material on the edge passes, there is no medium between the two groups of detection electric needles, and the two groups of detection electric needles are not energized; if there is no excess amount on the edge of the cold-rolled steel strip, both groups of detection electric needles are not energized; when the cold-rolled steel strip with excess material on the edge passes, both groups of detection electric needles are energized because of contact with the cold-rolled steel strip, and the second drive motor is started to rotate the rotating rod, and the rotating rod rotates. The moving rod carries the driven block to move toward the direction of the second drive motor, so that the moving bracket carries the second group of detection electric needles away from the first group of detection electric needles. If there is continued excess amount during the movement, the second group of detection electric needles will continue to be energized, and the second drive motor will continue to drive the second group of detection electric needles to move until there is no cold-rolled steel strip in the middle of the second group of detection electric needles. The second detection electric needles stop being energized, and the second drive motor stops driving. The distance moved is used to reflect the specific amount of excess cold-rolled steel strip at that location, which is convenient for subsequent adjustment of the grinding device for grinding.

[0014] Furthermore, the grinding mechanism includes a grinding head, a third drive motor and a fixed base. The grinding mechanism is placed in a grinding chamber. The grinding head is cylindrical. One end of the grinding head is fastened to the output end of the third drive motor. The fixed end of the third drive motor is fastened to the fixed base. The fixed base is connected to the grinding adjustment mechanism.

[0015] In the grinding mechanism, the mechanism is used to grind the cold-rolled steel strip and remove the excess part of the edge of the cold-rolled steel strip. The fixed base is tightly connected to the third drive motor to provide support. The grinding head is tightly connected to the output end of the third drive motor. The grinding head fits the normal edge of the cold-rolled steel strip, that is, fits the side wall of the cold-rolled steel strip without the excess part. Not only can the cold-rolled steel strip be better ground, but also the cold-rolled steel strip can be limited. If the cold-rolled steel strip is not completely ground, the grinding is stopped. During the process of the cold-rolled steel strip being wound, the excess part of the cold-rolled steel strip will be stuck with the grinding head, causing the cold-rolled steel strip to deviate, affecting the winding and subsequent grinding; the cold-rolled steel strip after being completely ground has no excess amount on its edge and can be wound normally without deviation.

[0016] Further, the grinding adjustment mechanism includes an angle adjustment device, which includes an arc plate, a telescopic rod, a first driving hydraulic cylinder and a second supporting plate. The angle adjustment device is connected to the grinding chamber, and the angle adjustment device is connected to the fixed base. The arc plate is a plate with an arc greater than 1 / 4, and a track is provided on the arc plate. A sliding groove is provided at the bottom of the fixed base. The arc plate is slidably connected to the fixed base, the arc plate and the second supporting plate are tightly connected, the second supporting plate is slidably connected to the wall of the grinding chamber, and a moving groove is provided on the second supporting plate. The first driving hydraulic cylinder and the second supporting plate are connected, the fixed end of the first driving hydraulic cylinder is tightly connected to the wall of the moving groove, the telescopic rod is connected to the second supporting plate, the telescopic rod is slidably connected to the bottom wall of the moving groove, the first driving hydraulic cylinder and the telescopic rod are tightly connected, and one end of the telescopic rod away from the moving groove is hinged to the side wall of the fixed base, the angle adjustment device is connected to the dust removal mechanism, and the second supporting plate is connected to the dust removal mechanism. The grinding adjustment mechanism also includes a second driving hydraulic cylinder, the second driving hydraulic cylinder is connected to the angle adjustment device, the output end of the second driving hydraulic cylinder is tightly connected to the second support plate, and the second driving hydraulic cylinder is tightly connected to the wall of the grinding chamber.

[0017] In the grinding adjustment mechanism, the mechanism is used to adjust the position of the grinding mechanism, the angle adjustment device is used to adjust the angle of the grinding mechanism, the arc plate is a plate with an arc greater than 1 / 4, the grinding mechanism moves on the arc plate through a fixed base, the second support plate fixedly supports the arc plate, the first driving hydraulic cylinder is tightly connected to the inner wall of the moving groove, one end of the telescopic rod is slidably connected to the bottom wall of the moving groove, and the other end is hinged to the fixed base, the second driving hydraulic cylinder is tightly connected to the second support plate, and is used to push the second support plate to move along the wall of the grinding chamber. After the device is started, the fixed base is placed at the bottom of the arc plate in the initial state, and the grinding head is in a vertical state at this time. The grinding head is perpendicular to the cold-rolled steel strip and is used to grind the part with more excess. At this time, the contact area between the grinding head and the cold-rolled steel strip is the smallest. The third driving motor drives the grinding head to rotate, the speed of the grinding head increases, and the grinding amount of the cold-rolled steel strip by the grinding head becomes larger. More cold-rolled steel strips at the same position can be ground at the same time. For the situation where there is a lot of excess at the edge of the cold-rolled steel strip, the angle adjustment device is driven to move by the second driving hydraulic cylinder, so that the grinding head can move with the cold-rolled steel strip to extend the grinding time. In another state, the first driving hydraulic cylinder is started, pushing the telescopic rod to move along the moving groove. During the movement, the telescopic rod is extended, and the telescopic rod and the fixed bottom The seat is hinged, and the fixed base is also slidably connected to the arc plate. During the movement of the telescopic rod, the telescopic rod will push the fixed base toward the other end of the arc plate until it reaches the top. At this time, the grinding head is horizontal and parallel to the cold-rolled steel strip, which is used to grind the part with less excess. The contact area between the grinding head and the cold-rolled steel strip is the largest. The third drive motor drives the grinding head to rotate. The grinding head has a normal speed and can grind a wider range of cold-rolled steel strips of the same amount in the same time. After the device is started, the angle of the grinding head is adjusted according to the steel strip detection mechanism. If both sets of detection electric needles are not energized, the angle adjustment device and the grinding mechanism will not start; if only the first set When the detection electric needles are energized or both groups are energized, but the second group is energized for a shorter time, the first drive hydraulic cylinder pushes the telescopic rod to move, and the third drive motor is started, so that the fixed base moves along the arc plate to the uppermost end. At this time, the grinding head and the cold-rolled steel strip are ground in parallel, the grinding amount is small, and the grinding range is large; if both groups of detection electric needles are energized and the duration is long, the angle adjustment device is not started, only the grinding mechanism is started, and the grinding head accelerates to grind the cold-rolled steel strip, the grinding range is small but the grinding amount is large. Grinding with adjusted angles in this way can not only improve the grinding efficiency and quality, but also extend the service life of the grinding head through angle changes.

[0018] Furthermore, the dust removal mechanism includes a dust removal fan and a dust removal nozzle. The dust removal mechanism is placed in the grinding chamber. The dust removal fan and the dust removal nozzle are connected through a pipeline. The dust removal fan is fastened to the second support plate, and the dust removal nozzle faces between the grinding head and the cold-rolled steel strip.

[0019] In the dust removal mechanism, this mechanism is used to continue to remove the debris generated during the grinding process to prevent it from affecting normal grinding, and if the debris falls on the cold-rolled steel strip, it may affect the winding. The dust removal fan is equipped with fan blades, and the fan blades are driven to rotate by a servo motor, so that a negative pressure difference is generated between the inside of the dust removal fan and the outside world. The external air carries the debris and dust into the dust removal fan from the dust removal nozzle. Therefore, the debris and dust generated by grinding can be sucked into the fan through the dust removal fan and the dust removal nozzle to prevent it from falling on the cold-rolled steel strip and affecting subsequent operations.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: after the present invention is started, the cold-rolled steel strip after cold rolling enters the grinding chamber from the feeding port, and the winding roller is driven by the first driving motor to slowly move the cold-rolled steel strip. During this process, the cold-rolled steel strip is in a tightened state, and two groups of detection electric needles are used to detect the excess amount at the edge of the cold-rolled steel strip. When the cold-rolled steel strip without excess material at the edge passes, there is no medium between the two groups of detection electric needles, the two groups of detection electric needles are not energized, the angle adjustment device and the grinding mechanism are not started, and the cold-rolled steel strip passes normally; if only the first detection electric needle is energized or both groups are energized, but the second group is energized for a shorter time, the first driving hydraulic cylinder pushes the telescopic rod to move, and the third driving motor is started, so that the fixed base moves along the arc plate, and the moving Move to the uppermost end, at this time, the grinding head and the cold-rolled steel strip are grinding in parallel, the grinding amount is small, and the grinding range is large; if both sets of detection electric needles are energized and the duration is long, the angle adjustment device will not start, only the grinding mechanism will start, the grinding head will accelerate to grind the cold-rolled steel strip, the grinding range is small but the grinding amount is large, at the same time, for the situation where there is a lot of excess on the edge of the cold-rolled steel strip, the second driving hydraulic cylinder drives the angle adjustment device to move, so that the grinding head can move with the cold-rolled steel strip, the grinding time is extended, and the cold-rolled steel strip can be better polished. After completion, the grinding head is driven to grind in parallel, and the second driving hydraulic cylinder returns to the original position to continue grinding. The debris generated by grinding is cleaned by the dust removal mechanism, and the cold-rolled steel strip after grinding is wound up by the winding roller. BRIEF DESCRIPTION OF THE DRAWINGS

When the cold-rolled steel strip with no excess material on the edge passes, there is no medium between the two groups of detection electric needles 31, and the two groups of detection electric needles 31 are not energized; if there is no excess amount on the edge of the cold-rolled steel strip, the two groups of detection electric needles 31 are not energized; when the cold-rolled steel strip with excess material on the edge passes, the two groups of detection electric needles 31 are energized because of contact with the cold-rolled steel strip, and the second drive motor 36 is started, so that the rotating rod 34 rotates The rotating rod 34 moves with the driven block 35 toward the second drive motor 36, so that the moving bracket 33 moves the second group of detection electric needles 31 away from the first group of detection electric needles 31. If there is a continuous excess amount during the movement, the second group of detection electric needles 31 will continue to be energized, and the second drive motor 36 will continue to drive the second group of detection electric needles 31 to move until there is no cold-rolled steel strip in the middle of the second group of detection electric needles 31. The second detection electric needles 31 stop being energized, and the second drive motor 36 stops driving. The distance moved is used to reflect the specific amount of excess cold-rolled steel strip at this location, which is convenient for subsequent adjustment of the grinding device for grinding.

The fixed end of the third drive motor 42 is fastened to the fixed base 43. The fixed base 43 is connected to the grinding adjustment mechanism 5.

[0041] In the grinding mechanism 4, the mechanism is used to grind the cold-rolled steel strip and remove the excess part of the edge of the cold-rolled steel strip. The fixed base 43 and the third drive motor 42 are tightly connected to provide support. The grinding head 41 and the output end of the third drive motor 42 are tightly connected. The grinding head 41 fits the normal edge of the cold-rolled steel strip, that is, fits the side wall of the cold-rolled steel strip without the excess part. Not only can the cold-rolled steel strip be better ground, but also the cold-rolled steel strip can be limited. If the cold-rolled steel strip is not completely ground, the grinding is stopped. During the process of the cold-rolled steel strip being wound, the excess part of the cold-rolled steel strip will be stuck with the grinding head 41, causing the cold-rolled steel strip to deviate, affecting the winding and subsequent grinding; the cold-rolled steel strip after being completely ground has no excess at its edge and can be wound normally without deviation.

[0042] The grinding adjustment mechanism 5 includes an angle adjustment device 51, which includes an arc plate 511, a telescopic rod 512, a first driving hydraulic cylinder 513 and a second supporting plate 514.

The fixed end of the first driving hydraulic cylinder 513 is tightly connected to the wall of the movable groove 5141, the telescopic rod 512 is connected to the second support plate 514, the telescopic rod 512 is slidably connected to the bottom wall of the movable groove 5141, the first driving hydraulic cylinder 513 is tightly connected to the telescopic rod 512, the end of the telescopic rod 512 away from the movable groove 5141 is hinged to the side wall of the fixed base 43, the angle adjustment device 51 is connected to the dust removal mechanism 6, the second support plate 514 is connected to the dust removal mechanism 6, the grinding adjustment mechanism 5 also includes a second driving hydraulic cylinder 52, the second driving hydraulic cylinder 52 is connected to the angle adjustment device 51, the output end of the second driving hydraulic cylinder 52 is tightly connected to the second support plate 514, and the second driving hydraulic cylinder 52 is tightly connected to the wall of the grinding chamber 111.

[0043] In the grinding adjustment mechanism 5, the mechanism is used to adjust the position of the grinding mechanism 4, the angle adjustment device 51 is used to adjust the angle of the grinding mechanism 4, the arc plate 511 is a plate greater than 1 / 4 arc, the grinding mechanism 4 moves on the arc plate 511 through the fixed base 43, the second support plate 514 fixedly supports the arc plate 511, the first driving hydraulic cylinder 513 is fastened to the inner wall of the moving groove 5141, one end of the telescopic rod 512 is slidably connected to the bottom wall of the moving groove 5141, and the other end is hinged to the fixed base 43, the second driving hydraulic cylinder 52 is fastened to the second support plate 514, and is used to push the second support plate 514 to move along the wall of the grinding chamber 111. After the device is started, the fixed base 43 is placed on the arc plate 511 in the initial state. At the bottom, the grinding head 41 is in a vertical state, perpendicular to the cold-rolled steel strip, and is used to grind the part with more excess. At this time, the contact area between the grinding head 41 and the cold-rolled steel strip is the smallest, and the third driving motor 42 drives the grinding head 41 to rotate. The rotation speed of the grinding head 41 increases, and the grinding amount of the cold-rolled steel strip by the grinding head 41 becomes larger. More cold-rolled steel strips can be ground at the same position in the same time. For the situation where there is a lot of excess at the edge of the cold-rolled steel strip, the angle adjustment device 51 is driven to move by the second driving hydraulic cylinder 52, so that the grinding head 41 can move with the cold-rolled steel strip to extend the grinding time; in another state, the first driving hydraulic cylinder 513 is started, pushing the telescopic rod 512 to move along the moving groove 5141. During the movement, the telescopic rod 512 is extended. , and the telescopic rod 512 and the fixed base 43 are hinged, and the fixed base 43 is also slidably connected to the arc plate 511. During the movement of the telescopic rod 512, the telescopic rod 512 will push the fixed base 43 toward the other end of the arc plate 511 until it reaches the top. At this time, the grinding head 41 is in a horizontal state and parallel to the cold-rolled steel strip, which is used to grind the part with less excess. The contact area between the grinding head 41 and the cold-rolled steel strip is the largest. The third drive motor 42 drives the grinding head 41 to rotate. The grinding head 41 has a normal speed and can grind a larger range of cold-rolled steel strips of the same amount in the same time. After the device is started, the angle of the grinding head 41 is adjusted according to the steel strip detection mechanism 3. If both sets of detection electric needles 31 are not energized, the angle adjustment device 51 and the grinding mechanism 4 are not started; if only the first detection electric needle 31 is energized or both groups are energized, but the second group is energized for a shorter time, the first driving hydraulic cylinder 513 pushes the telescopic rod 512 to move, and the third driving motor 42 is started, so that the fixed base 43 moves along the arc plate 511 to the uppermost end. At this time, the grinding head 41 and the cold-rolled steel strip are ground in parallel, the grinding amount is small, and the grinding range is large; if both groups of detection electric needles 31 are energized and the duration is long, the angle adjustment device 51 is not started, only the grinding mechanism 4 is started, and the grinding head 41 accelerates the grinding of the cold-rolled steel strip, the grinding range is small but the grinding amount is large, so that the grinding with adjusted angle can not only improve the grinding efficiency and quality, but also extend the service life of the grinding head 41 through the change of angle.

[0044] The dust removal mechanism 6 includes a dust removal fan 61 and a dust removal nozzle 62. The dust removal mechanism 6 is placed in the grinding chamber 111. The dust removal fan 61 and the dust removal nozzle 62 are connected through a pipeline. The dust removal fan 61 is fastened to the second support plate 514, and the dust removal nozzle 62 faces between the grinding head 41 and the cold-rolled steel strip.

[0045] In the dust removal mechanism 6, the mechanism is used to continue to remove the debris generated during the grinding process to prevent it from affecting normal grinding, and if the debris falls on the cold-rolled steel strip, it may affect the winding. The dust removal fan 61 is provided with fan blades inside, and the fan blades are driven to rotate by a servo motor to create a negative pressure difference between the inside of the dust removal fan 61 and the outside world. The external air carries the debris and dust into the dust removal fan 61 from the dust removal nozzle 62. Therefore, the debris and dust generated by grinding can be sucked into the fan through the dust removal fan 61 and the dust removal nozzle 62 to prevent it from falling on the cold-rolled steel strip and affecting subsequent operations.

[0046] Working principle of the present invention: after the present invention is started, the cold-rolled steel strip after cold rolling enters the grinding chamber 111 from the feed port 112, and the winding roller 22 is driven by the first drive motor 21 to slowly move with the cold-rolled steel strip. During this process, the cold-rolled steel strip is in a tightened state, and the two groups of detection electric needles 31 are used to detect the excess amount of the edge of the cold-rolled steel strip. When the cold-rolled steel strip without excess material on the edge passes, there is no medium between the two groups of detection electric needles 31, and the two groups of detection electric needles 31 are not powered, the angle adjustment device 51 and the grinding mechanism 4 are not started, and the cold-rolled steel strip passes normally; if only the first group of detection electric needles 31 is powered or both groups are powered, but the second group is powered on for a shorter time, the first drive hydraulic cylinder 513 pushes the telescopic rod 512 to move, and the third drive motor 42 is started, so that the fixed base 43 moves along the arc plate 511, Move to the uppermost end, at which time the grinding head 41 and the cold-rolled steel strip are grinding in parallel, with a small grinding amount and a large grinding range; if both sets of detection electric needles 31 are energized and the duration is long, the angle adjustment device 51 will not be started, and only the grinding mechanism 4 will be started, and the grinding head 41 will accelerate the grinding of the cold-rolled steel strip, with a small grinding range but a large grinding amount. At the same time, for the case where there is a lot of excess at the edge of the cold-rolled steel strip, the angle adjustment device 51 is driven to move by the second driving hydraulic cylinder 52, so that the grinding head 41 can move with the cold-rolled steel strip, extending the grinding time and being able to better grind the cold-rolled steel strip. After completion, the grinding head 41 is driven to grind in parallel, and the second driving hydraulic cylinder 52 returns to its original position to continue grinding. The debris generated by grinding is cleaned by the dust removal mechanism 6, and the cold-rolled steel strip after grinding is wound up by the winding roller 22.
