Description

Technical Field

[0001] The utility model belongs to a coiler, and in particular relates to an inlet precision edge guide device for a stainless steel coiler. Background Art

[0002] The coiler is an auxiliary equipment in a steel rolling workshop that coils steel into a roll shape; after searching, the prior art announcement number CN221086779U is a coiler with a tail anti-deviation adjustment mechanism for tin-plated steel plate processing. The photoelectric sensor will detect the deviation direction. At this time, the electric push rod pushes or contracts to drive the slider on the first slide to move on the slide rail. The movement of the slider drives the correcting roller to adjust the angle. The deviation of the correcting roller drives the slider installed at the other end to move on the second slide. The deviation between the correcting roller and the galvanized steel plate is adjusted to offset in the opposite direction, so that the galvanized steel plate is corrected by the correcting roller. The correcting roller is pushed and contracted by the electric push rod to adjust the angle of the correcting roller. The disadvantage is that it is impossible to accurately control how many degrees should be adjusted according to the offset of the steel plate so that the correcting roller can just correct the steel plate. Too large and too small angles will cause the steel coil to deviate. At the same time, when the steel coil is rolled up, the feeding is generally offset. If the angle is not adjusted well, the subsequent steel plate tilt angle will become larger.

[0003] After searching, the prior art publication number is CN112207147A, which is a coiler capable of automatic deviation correction. During the opening process of the deviation correction drive member, the power-assisted drive member is opened to drive the abutment sleeve to rotate actively. Since the abutment sleeve is in a truncated cone shape as a whole, the linear speed of the abutment sleeve and the corresponding abuttable position on the side wall of the coiled strip can be close when the abutment sleeve rotates, so that the abutment sleeve and the side wall of the strip can be approximately rotated synchronously when they abut, thereby further reducing the friction generated by the abutment sleeve and the side wall of the strip. The disadvantage is that the spacing between the two abutment sleeves cannot be determined, and the spacing may be too small, causing the strip to be squeezed into an arc shape, affecting the quality. At the same time, the abutment sleeve and the strip are driven to rotate synchronously by abutment, which is achieved by the mutual friction between the two, and cannot reduce wear very well.

[0004] In combination with the above technical scheme, the existing coiler edge guide device has a problem that when the steel plate is offset, the angle of the correction roller cannot be determined according to the offset angle, which makes it impossible for the correction roller to more accurately ensure the steel coil correction operation. At the same time, in the prior art, the guide roller has a short life and is easily worn during use. After a piece of it is rubbed off, the guide roller is deformed and the steel coil cannot be accurately guided and corrected. The utility model provides a stainless steel coiler entrance precision edge guide device to solve the above problems. Summary of the invention

[0038] A precise edge guide device for the entrance of a stainless steel coiler, the working process is as follows:

[0039] When in use, the cut stainless steel is moved to the side guide mechanism 3 at the front end of the conveying roller mechanism 2 through the conveying equipment. When the conveying equipment feeds the side guide mechanism, the steel plate is prone to offset, causing the coil of the coiler to deform. Therefore, when the steel plate moves to the side guide mechanism 3, the anti-warping component 32 is started, and the threaded column Ⅰ321 is driven to rotate by the forward and reverse motor Ⅱ324. The threaded column Ⅰ321 drives the clamping plate Ⅰ322 to move upward, so that the distance between the clamping plate Ⅰ322 and the clamping plate Ⅱ325 is greater than the thickness of the steel plate. After the steel plate moves between the lifting guide rollers 36, the sliding plate driving component 38 is immediately started, and the forward and reverse motor Ⅲ38 is driven to rotate. 2 drives the bidirectional lead screw 383 to rotate, so that the sliding plates 37 are close to each other, and the lifting guide rollers 36 on both sides are driven to squeeze the steel plate toward the middle. The guide rollers 361 on both sides are moved toward the middle to correct the deviation of the steel plate. At the same time, the forward and reverse motor I365 is started to drive the pressing plate I322 to move downward so that it contacts the steel plate. At this time, the forward and reverse motor I365 is started to drive the threaded column II363 to rotate. The threaded column II363 is connected to the cross plate through a thread. When the forward and reverse motor I365 drives the threaded column II363 to rotate, it also drives the guide roller 361 to rotate and lift, so that only one point of the guide roller 361 contacts the side of the steel plate. The guide roller 361 is easily rubbed out of grooves, so that the guide rollers are moved closer to the middle of the guide steel plate position in the later stage. Due to the friction of the guide rollers on both sides, the guide correction is deviated, which affects the use. The threaded column Ⅱ 363 drives the guide roller 361 to rotate and rise and fall, so that the contact point between the guide roller 361 and the steel plate is uniform, which increases the service life of the guide roller. When the guide roller 361 moves up and down, it may cause the edges of the steel plate to warp, affecting the product quality. Therefore, an anti-warping component 32 is also provided on the guide roller 361, which drives the pressing plate Ⅰ 322 to move closer to the middle through the forward and reverse motor Ⅱ 324, so that the pressing plate Ⅰ 322 and the pressing plate Ⅱ 325 clamp the steel plate. At the same time, rollers are provided on the opposite sides of the pressing plate to reduce the friction between the steel plate and the steel plate. At the same time, when the steel plate moves to the lower end of the anti-extrusion component 31, the anti-extrusion component 31 senses whether the steel plate has protrusions through the proximity switch 312 provided at the upper end, thereby preventing the sliding plate 37 from passing through the guide roller 361 and moving too close to the middle, causing the steel plate to be squeezed and deformed. When the three proximity switches 312 detect different distances, the forward and reverse motor III 382 on the sliding plate driving component 38 is controlled to rotate, so that the sliding plate 37 moves a certain distance to the outside to prevent excessive squeezing of the steel plate and deformation of the steel plate.
