Description

Technical Field

[0001] The present invention relates to the technical field of steel strip slitting machines, and particularly to a steel strip slitting machine with guiding and adjusting functions. Background Art

[0002] In the prior art, the slitting process of steel strips is usually completed by a decoiler, a slitting machine, and a rewind machine together. That is, the decoiler continuously conveys the steel strip to the slitting machine, the slitting machine cuts the steel strip into slitted steel strips, and then the rewind machine winds up the slitted steel strips. During this process, a buffer tank capable of accommodating a certain length of steel strip is provided between the decoiler and the slitting machine, and between the slitting machine and the rewind machine, respectively, for adjusting the running speed difference between the decoiler, the slitting machine, and the rewind machine to ensure the tension of the steel strip conveying. However, when the steel strip enters the buffer tank, the steel strip entering the buffer tank is in a loose state, and due to the need to increase the unwinding speed of the decoiler, the steel strip in the buffer tank is easily affected by the unwinding speed of the decoiler and shakes, resulting in easy friction between the steel strip and the inner wall of the buffer tank during the steel strip conveying process, causing damage to the surface of the steel strip and reducing the quality of the steel strip.

[0003] In summary, the present application proposes a steel strip slitting machine with guiding and adjusting functions to improve the above-mentioned technical problems. Summary of the Invention

[0045] With Figure 1Based on the perspective orientation, the side where the label of the chassis 1 is located is the front, and the side where the label of the first rotating roller 4 is located is the left. Here, it should be noted that the external unwinder is located on the left side of the chassis 1, and the external rewinder is located on the right side of the chassis 1.

[0046] The following is a detailed description of the slitting process of the stainless steel strip 6:

[0047] For the convenience of description, as Figure 1 shown, the first rotating roller 4 and the second rotating roller 5 connected to the two corresponding fixed frames 3 before and after together form a rotating roller group. There are a total of four rotating roller groups on the chassis 1, which are abbreviated as the first rotating roller group, the second rotating roller group, the third rotating roller group, and the fourth rotating roller group from left to right. Note that the slitting mechanism 2 is located between the second rotating roller group and the third rotating roller group. During slitting, first control all the first electric sliders 202 to drive the corresponding fixed frames 3 to move leftward on the first slide rail 201, so that the corresponding rotating roller groups all move to the leftmost side of the first slide rail 201. At the same time, control the electric push rods on the fixed frames 3 to drive the corresponding sliding plates 3001 and the second rotating rollers 5 to move upward. Then the staff passes the end of the stainless steel strip 6 on the left unwinder through the first rotating roller group and the second rotating roller group in sequence, and the end of the stainless steel strip 6 extends 0.2 m to the right from the second rotating roller group. Then control the electric push rod corresponding to the second rotating roller group to move downward, so that the corresponding second rotating roller 5 in the second rotating roller group moves downward, and cooperate with the corresponding first rotating roller 4 in the second rotating roller group to clamp the stainless steel strip 6. Subsequently, control the first electric slider 202 to drive the second rotating roller group and the stainless steel strip 6 to move rightward, so that the stainless steel strip 6 straddles the left buffer groove 7. During this process, by controlling the electric push rod corresponding to the first rotating roller group to move downward, the corresponding second rotating roller 5 in the first rotating roller group moves downward to fit the upper surface of the stainless steel strip 6 (note that the stainless steel strip 6 is only in contact at this time and not clamped). Thus, when the second rotating roller group drives the stainless steel strip 6 to move rightward, the stainless steel strip 6 drives the corresponding first rotating roller 4 and the second rotating roller 5 in the first rotating roller group to rotate, so as to limit the stainless steel strip 6 through the first rotating roller group, avoid the shaking of the stainless steel strip 6 during rightward conveying, and improve the stability when pulling the stainless steel strip 6;

[0048] When the second roller group moves to the rightmost side corresponding to the first slide rail 201, the end of the stainless steel strip 6 sequentially passes through the guide plate group 2001 and the pinch roller group 2002 on the left side of the slitting mechanism 2. At this time, control the second roller group to release the stainless steel strip 6 (note that the second roller 5 on the second roller group is in contact with the surface of the stainless steel strip 6 at this time), and continuously convey the stainless steel strip 6 to the right through the pinch roller group 2002, so that the stainless steel strip 6 passes through the cutter group 2003. The cutter group 2003 cuts the stainless steel strip 6 into several strip steel strips 6001. Subsequently, the staff separates all the strip steel strips 6001 into two groups at intervals. One group passes through the lower side of the limit roller 2004, and the other group passes through the upper side of the limit roller 2004. Here, taking the example of cutting into three strip steel strips 6001 for description, the middle strip steel strip 6001 passes through the lower side of the limit roller 2004, and the front and rear strip steel strips 6001 pass through the upper side of the limit roller 2004. Then, the three strip steel strips 6001 sequentially pass through the third roller group and the fourth roller group, and control the electric push rod in the fourth roller group to drive the corresponding second roller 5 to move downward, so that the fourth roller group clamps the three strip steel strips 6001. Then, control the first electric slider 202 to drive the fourth roller group and the strip steel strips 6001 to move to the right, so that the strip steel strips 6001 straddle the buffer groove 7 on the right side. When the fourth roller group moves to the rightmost side corresponding to the first slide rail 201, the staff sequentially fixes the three strip steel strips 6001 on the winding roller of the winder, then controls the fourth roller group to release the strip steel strips 6001, and controls the winder to start continuously winding the strip steel strips 6001. Thus, the traction of the stainless steel strip 6 is completed. Compared with the prior art method of guiding the stainless steel strip 6 through the guide plate provided on the buffer groove 7, the clamping and guiding of the stainless steel strip 6 by the first roller 4 and the second roller 5 can reduce the friction area between the stainless steel strip 6 and the guide plate, avoid long strip scratches on the surface of the stainless steel strip 6 scratched by impurities on the guide plate, and compared with the guide plate, the first roller 4 and the second roller 5 are more convenient for the staff to clean;

[0049] During the traction of the stainless-steel strip 6, it is necessary to adjust the length of the stainless-steel strip 6 cached in the buffer tank 7. The specific operation is to adjust the speed at which the unwinder releases the stainless-steel strip 6, so that a certain length of the stainless-steel strip 6 is cached in the left buffer tank 7. During the adjustment process, due to the instability of the steel strip tension caused by the mismatch between the unwinding speed and the slitting speed, and the excessive length of the stainless-steel strip 6 located in the buffer tank 7, it is easy to cause the stainless-steel strip 6 to sway in the left and right directions in the buffer tank 7, which may easily lead to the collision of the stainless-steel strip 6 with the left and right inner walls of the buffer tank 7, resulting in damage to the stainless-steel strip 6. To avoid the above situation, before adjusting the length of the stainless-steel strip 6 cached in the buffer tank 7, first control the first electric slider 202 to drive the first roller group and the second roller group to move above the left buffer tank 7, so that there is a horizontal safety distance of more than 0.1 m between the first roller group and the left inner wall of the left buffer tank 7, and there is a horizontal safety distance of more than 0.1 m between the second roller group and the right inner wall of the left buffer tank 7. Subsequently, control the second electric slider 204 to drive the corresponding fixed frame 3, the first roller 4 and the second roller 5 in the first roller group to move upward on the second slide rail 203, so that the first roller group is higher than the second roller group, thereby driving the stainless-steel strip 6 to move upward above the buffer tank 7. In this way, it can be avoided that the stainless-steel strip 6 collides with the side wall of the buffer tank 7 due to swaying, ensuring the quality of the stainless-steel strip 6 after slitting. Subsequently, adjust the cached length of the stainless-steel strip 6 again, so that the stainless-steel strip 6 between the first roller group and the second roller group gradually increases. When the unwinder resumes the unwinding speed during normal slitting (note that when adjusting the unwinding speed of the unwinder to adjust the length of the stainless-steel strip 6 cached in the buffer tank 7, the unwinding speed of the unwinder is preset by the program. For example, when the length of the stainless-steel strip 6 cached in the buffer tank 7 needs to be 5 m, the corresponding unwinding speed and unwinding time of the unwinder are controlled by the program, and the rates of the corresponding rewinder and the slitting mechanism 2 are also controlled by the program), then control the second electric slider 204 to drive the first roller group to move downward to the initial position, and the stainless-steel strip 6 finally Figure 2 is located in the buffer tank 7 in the V-shaped state as shown. Similarly, following the same steps as above, the slitting steel strip 6001 can be driven by the fourth roller group to move upward, so that the slitting steel strip 6001 is located above the right buffer tank 7, thereby avoiding the collision of the slitting steel strip 6001 with the side wall of the right buffer tank 7 when adjusting the cached length of the slitting steel strip 6001 and improving the quality of the slitting steel strip 6001.

[0050] It should be noted that during the process of the first roller group driving the stainless steel strip 6 to move downward, the position of the lowest point of the stainless steel strip 6 is monitored in real time through the infrared sensor in the buffer groove 7 to prevent the stainless steel strip 6 from contacting the bottom of the buffer groove 7. If the lowest point of the stainless steel strip 6 reaches the sensing threshold of the infrared sensor and the first roller group has not moved to the initial position, it indicates that the buffer length of the stainless steel strip 6 is too long. At this time, it is necessary to pause the uncoiler from continuing to unwind and control the slitting mechanism 2 to continue cutting, so that the buffer length of the stainless steel strip 6 gradually decreases, and then control the first roller group to move downward to the initial position, and make the lowest point of the stainless steel strip 6 within the sensing threshold of the infrared sensor.

[0051] On this basis, debris generated by the slitting process and dust in the air are likely to adhere to the infrared sensor in the buffer tank 7, resulting in the infrared sensor being unable to accurately measure the buffer length of the stainless steel strip 6 or the slitting steel strip 6001. When the buffer length is too long, it is easy to cause the stainless steel strip 6 or the slitting steel strip 6001 to rub against the bottom of the buffer tank 7, resulting in scratches on the stainless steel strip 6 or the slitting steel strip 6001. To avoid the occurrence of the above situation, the electric push rod on the fixed frame 3 is controlled to drive the corresponding slide plate 3001 to move downward, so that the first roller 4 and the second roller 5 in all roller groups are in contact with the stainless steel strip 6 or the slitting steel strip 6001. In this way, it can be ensured that the first roller 4 and the second roller 5 rotate as the stainless steel strip 6 or the slitting steel strip 6001 is conveyed. The number of rotations of the first roller 4 is monitored by the rotary encoder on the first roller 4. At the same time, combined with the diameter of the first roller 4, the conveying length of the stainless steel strip 6 or the slitting steel strip 6001 passing through the first roller 4 can be calculated. Taking the left buffer tank 7 as an example, the conveying length calculated by the first roller group minus the conveying length calculated by the second roller group, and the result is zero, indicating that the buffer length in the buffer tank 7 remains unchanged. If the result is greater than zero, it indicates that the buffer length in the buffer tank 7 increases. In this way, the buffer length in the buffer tank 7 can be monitored by the rotary encoder, thereby avoiding the situation where the stainless steel strip 6 or the slitting steel strip 6001 rubs against the bottom of the buffer tank 7 due to a malfunction of the infrared sensor, thus improving the reliability of its monitoring. When the rotary encoder monitors that the buffer length in the buffer tank 7 exceeds the set threshold, the first roller group is controlled to clamp the stainless steel strip 6, and at the same time, the second electric slider 204 is controlled to drive the first roller group to move upward on the corresponding second slide rail 203, thereby driving the stainless steel strip 6 in the buffer tank 7 to move upward. In this way, it can be avoided that the stainless steel strip 6 rubs against the bottom of the buffer tank 7. At the same time, the uncoiler is controlled to pause releasing the stainless steel strip 6, so that the buffer length of the stainless steel strip 6 in the buffer tank 7 is reduced. When the buffer length returns to within the safe value, the first roller group is controlled to move downward to the initial position and cancel the clamping of the stainless steel strip 6, and at the same time, the uncoiler is controlled to continue releasing the stainless steel strip 6. In this way, the protection of the stainless steel strip 6 is completed. Similarly, the protection of the slitting steel strip 6001 in the right buffer tank 7 can be achieved according to the above steps.

[0052] It should be noted here that the rubber layer on the surfaces of the first roller 4 and the second roller 5 can increase the friction force between them and the stainless steel strip 6 or the slitting steel strip 6001, avoiding the situation where the stainless steel strip 6 or the slitting steel strip 6001 slips when moving to the right, resulting in the first roller 4 and the second roller 5 not rotating, so as to ensure the monitoring accuracy of the rotary encoder on the first roller 4.

[0053] It is also considered that when the three slit steel strips 6001 are conveyed in the right buffer groove 7, since the length of the slit steel strip 6001 in the buffer groove 7 is relatively long and its moving space is not restricted, and at the same time, since the width of the slit steel strip 6001 is relatively narrow, it is easy to shake in the front-back direction, so that adjacent two slit steel strips 6001 are prone to friction, resulting in scratches on their surfaces. To solve the above problems, after the fourth roller group pulls the slit steel strip 6001 through the right buffer groove 7, the staff respectively insert the two limiting rods 401 into the corresponding fixed sockets 1001, and then insert the new limiting rods 401 into the insertion holes 40102 of the left limiting rod 401 and the right limiting rod 401 respectively. Its final state is as Figure 6 shown in the stacked state. Then, with the front-to-back view as the reference, control the second motor 402 on the left to drive the left limiting rod 401 to rotate clockwise, and control the second motor 402 on the right to drive the right limiting rod 401 to rotate counterclockwise until the limiting rod 401 fits with the slit steel strip 6001. Its state diagram is as Figure 7 shown. With the front-to-back count as the reference, the odd-numbered slit steel strips 6001 are located between the two first collars 40103, while the even-numbered slit steel strips 6001 are in contact with the corresponding first collars 40103, so that the bending amplitude of the even-numbered slit steel strips 6001 is greater than that of the odd-numbered slit steel strips 6001, as Figure 7 and Figure 8 shown, so that the slit steel strips 6001 are separated and misaligned from each other, and the slit steel strips 6001 are restricted to avoid the situation that adjacent two slit steel strips 6001 are prone to friction and cause scratches on their surfaces, thereby improving the slitting quality of the slit steel strips 6001.

[0054] Furthermore, second collars 4001 and third collars 5001 are respectively added to the first rollers 4 and the second rollers 5 on the third roller group and the fourth roller group. When the slit steel strip 6001 passes through the third roller group and the fourth roller group, the odd-numbered slit steel strips 6001 are supported on the second collars 4001, the even-numbered slit steel strips 6001 are supported on the first rollers 4, and the second rollers 5 restrict the odd-numbered slit steel strips 6001, and the third collars 5001 restrict the even-numbered slit steel strips 6001 to cooperate with the limiting rods 401 and the first collars 40103 thereon to comprehensively restrict the slit steel strips 6001 after slitting and completely avoid the problem of surface scratches caused by the shaking of the slit steel strips 6001.

[0055] It is also considered that, for the reasons of increasing friction and protecting the surface of the stainless steel strip 6, the surfaces of the second set of rings 4001 and the third set of rings 5001 are both covered with rubber layers. After the slitting steel strip 6001 is cut by the cutter group 2003, burrs will inevitably be generated at the edges of the slitting steel strip 6001. When the burrs continuously pass through the second set of rings 4001 and the third set of rings 5001, it is easy to scratch the rubber layers on their surfaces. Therefore, in order to ensure the service life of the rubber layer and the surface quality of the stainless steel strip 6, it is necessary to clean the burrs at the edges of the slitting steel strip 6001; the specific cleaning operation is as follows: when the three slitting steel strips 6001 are divided into upper and lower layers by the limiting roller 2004, control the driving member 301 to drive the corresponding mounting plate 302 to move towards each other. It should be noted that the position of the scraper 303 on the mounting plate 302 has been adjusted according to the width of the slitting steel strip 6001 as required before use. There are corresponding scrapers 303 on the front and rear edges of each slitting steel strip 6001. When the mounting plate 302 fits on the surface of the corresponding slitting steel strip 6001, the scraper 303 fits on the corresponding edge part, and the burrs at the edges of the slitting steel strip 6001 are shaved off by the scraper 303, so as to avoid the situation that the burrs contact the rubber layer for a long time and reduce the service life of the rubber layer, and ensure the surface quality of the slitting steel strip 6001; it is hereby stated that the shaved burrs fall down into the collection box 304, and the staff regularly cleans the burrs in the collection box 304.

[0056] On this basis, it is also considered that after the slitting steel strip 6001 passes through the cutter group 2003 and the third roller group, the slitting steel strip 6001 immediately enters the buffer groove 7 on the right side, and the slitting steel strip 6001 in the buffer groove 7 is in a relaxed state. Therefore, the slitting steel strip 6001 between the cutter group 2003 and the third roller group is also in a relaxed state. Thus, when the relaxed slitting steel strip 6001 passes through the scraper 303, it is easy to shake, which is not conducive to the fitting of the scraper 303 with the edge of the slitting steel strip 6001 and reduces the quality of deburring. For this reason, during the conveying process of the slitting steel strip 6001, control the electric push rod on the fixed frame 3 to drive the corresponding second roller 5 of the third roller group to press the slitting steel strip 6001 downward, and at the same time, with the front-to-back view as the reference, control the first motor 205 to drive the corresponding second roller 5 to rotate counterclockwise, so as to continuously convey the slitting steel strip 6001 to the right actively through the third roller group, keep the slitting steel strip 6001 between the cutter group 2003 and the third roller group under tension, so as to ensure that the slitting steel strip 6001 is in a stable state when passing through the scraper 303 and ensure the deburring effect.

[0057] Example 2: On the basis of Example 1, referring to Figure 1 and Figures 12-14As shown in the figure, further, to avoid creases in the slitting steel strip 6001 and improve the quality of the slitting steel strip 6001, the diameter of the limiting rod 401 is set to be greater than the minimum bending radius of the slitting steel strip 6001.

[0058] Considering that during the winding process of the slitting steel strip 6001 by the winder, due to improper operation and unstable equipment operation, etc., it is easy to cause the set winding tension and slitting speed to not match, resulting in insufficient winding tension and then the situation of loose winding. At this time, it is necessary to control the winder to unwind, release the loose slitting steel strip 6001, and then wind it again. However, the released slitting steel strip 6001 is likely to fall to the ground or overlap with each other, causing damage to the surface of the slitting steel strip 6001 and reducing the winding quality. Therefore, before the winder unwinds, first control the second motor 402 to drive the limiting rod 401 to rotate to the initial position, and then the staff removes the two limiting rods 401 on the upper side from the corresponding limiting rods 401 respectively. As Figure 12 shown, keep the lowermost limiting rod 401. At this time, the slitting steel strip 6001 is located below the limiting rod 401, and the fourth roller group is located above the right limiting rod 401. Then control the fourth roller group to clamp the slitting steel strip 6001, and drive the fourth roller group to pass above the right limiting rod 401 through the first electric slider 202, so that the slitting steel strip 6001 continuously moves to the left, thereby tightening the slitting steel strip 6001 located in the buffer groove 7, and control the winder to release the slitting steel strip 6001 synchronously. When the fourth roller group moves to the upper left of the left limiting rod 401, at this time, the slitting steel strip 6001 forms a U shape with the opening facing to the right on the first roller 4 corresponding to the fourth roller group. Then insert another limiting rod 401 through the middle of the U shape, and insert the insertion part 40101 of the limiting rod 401 into the corresponding jack 40102 of the lower limiting rod 401. Then control the fourth roller group to release the slitting steel strip 6001, and control the second electric slider 204 to drive the fourth roller group to move to the upper right of the right limiting rod 401, and insert the new limiting rod 401 on the right limiting rod 401 according to the same steps as above. Repeat the operation like this. As Figure 14 shown, wind the slitting steel strip 6001 released by the winder around the limiting rod 401 through the fourth roller group, so that the slitting steel strip 6001 is distributed in a Z shape between the limiting rods 401, thereby realizing the temporary storage of the slitting steel strip 6001 released by the winder, avoiding the situation that the slitting steel strip 6001 falls to the ground or overlaps with each other, and thus improving the winding quality of the slitting steel strip 6001. It should be noted that since the diameter of the limiting rod 401 is set to be greater than the minimum bending radius of the slitting steel strip 6001, it is ensured that the slitting steel strip 6001 will not be excessively bent when passing through the limiting rod 401, thereby avoiding creases in the slitting steel strip 6001 and improving the quality of the slitting steel strip 6001.
