[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0026] As Figure 1 , the present application provides a strip steel processing system for preventing strip steel from being scratched, comprising a plurality of strip steel processing devices arranged in sequence, and conveying guide plates arranged between at least some adjacent strip steel processing devices, wherein at least some of the conveying guide plates are scratch-preventing guide plates, and the working plate surface of the scratch-preventing guide plates is provided with a scratch-preventing structure.

[0027] In the embodiment, the scratch-preventing structure provided on the working plate surface of the guide plate can reduce or even avoid the scratch of the contacted head and tail sections of the strip steel, thereby effectively improving the surface quality of the strip steel.

[0028] In one of the embodiments, as Figures 2-6 , at least some of the scratch-preventing guide plates are roller guide plates 1, and the roller guide plate 1 comprises a first guide plate body 12 and a plurality of conveying rollers 11, wherein the plurality of conveying rollers 11 are arranged in sequence along the running direction of the strip steel, each of the conveying rollers 11 is rotatably installed on the working plate surface of the first guide plate body 12 through a roller support, and the axis of the conveying roller 11 is parallel to the horizontal direction and perpendicular to the running direction of the strip steel.

[0029] By providing the conveying roller 11 on the first guide plate body 12, the rolling contact with the head and tail of the strip steel can be achieved, thereby reducing or even avoiding the scratch of the contacted head and tail sections of the strip steel.

[0030] In this case, the conveying roller 11 with a small diameter can be used, and the rotational inertia and inertia are small, so that the conveying roller 11 can smoothly rotate with the movement of the strip steel.

[0031] Preferably, the conveying roller 11 is rubberized on the surface with good hardness and wear resistance, so that the strip steel can be prevented from being scratched.

[0032] In this case, as Figure 6Each conveying roller 11 can include a plurality of roller segments 110 arranged in sequence along the axial direction, which can not only reduce the weight and cost of the roller guide 1, but also reduce the contact area between the conveying roller 11 and the strip, thereby further preventing the strip from being scratched; moreover, since the strip acting force on the roller segments 110 at different positions in the width direction of the strip can be different, the wear degree of different roller segments 110 can also be different, and thus the above design is also beneficial to the maintenance of the conveying roller 11. The roller segments 110 on the first guide body 12 can be arranged in an array or in an irregular manner, for example, the roller segments 110 of two adjacent conveying rollers 11 are staggered in the width direction of the first guide body 12 (parallel to the axial direction of the conveying roller 11), that is, the end faces (end faces are perpendicular to the roller axis) of the roller segments 110 of the two conveying rollers 11 are not coplanar, which can ensure reliable guiding of strips of different width specifications.

[0033] In one embodiment, as Figure 4 and Figure 5 At least part of the roller guide 1 is formed with an inclined conveying section 111, in which the distance between the top end of each conveying roller 11 and the first guide body 12 gradually increases in the running direction of the strip.

[0034] Based on the above-mentioned inclined conveying section 111, a guide slope can be formed, which can reliably guide the strip, especially the strip head, and improve the smoothness and safety of threading. When threading between two adjacent groups of pinch units, the strip head sinks under its own weight after passing through the previous pinch unit and hits the next pinch unit. By arranging the above-mentioned conveying guide, the guide slope based on the inclined conveying section 111 can receive and guide the strip head, so that the strip head enters the next group of pinch units in the tangential direction of the inclined conveying section 111, thereby avoiding damage to the pinch units and the strip head. The above-mentioned roller guide 1 can be a fixed guide, so that the strip head outlet of the inclined conveying section 111 matches and connects with the next pinch unit; when the above-mentioned roller guide 1 is a swing guide, the swing of the roller guide 1 can better realize the connection between the roller guide 1 and the front and rear pinch units.

[0035] For the above-mentioned inclined conveying section 111, as one of the ways, Figure 4 the diameter of each conveying roller 11 gradually increases in the running direction of the strip; wherein the axis of each conveying roller 11 is preferably in the same horizontal plane; this case is particularly suitable for being arranged in a section with short transportation distance and small space.

[0036] For the above-mentioned inclined conveying section 111, as one of the ways, Figure 5The distance between the axis of each conveying roller 11 and the first guide plate body 12 gradually increases along the strip steel running direction; wherein, the diameter of each conveying roller 11 is preferably the same; in this case, the roller specifications are less, and the structure is simple, and it is especially suitable for being arranged in a section with medium transportation distance.

[0037] In one of the embodiments, as shown in Figure 5 At least part of the roller guide plate 1 is formed with a horizontal conveying section 112 and is further formed with the inclined conveying section 111 upstream and / or downstream of the horizontal conveying section 112; in the horizontal conveying section 112, the distance between the top end of each conveying roller 11 and the first guide plate body 12 is the same. The combination of the horizontal conveying section 112 and the inclined conveying section 111 can improve the guiding reliability of the strip steel, especially in a section with long transportation distance, by arranging the inclined conveying section 111 upstream and downstream of the horizontal conveying section 112, the strip head can be reliably and smoothly received from the upstream pinch unit and guided to the downstream pinch unit.

[0038] In one of the embodiments, as shown in Figure 7 and Figure 8 At least part of the anti-scratch guide plate is a hair-planted guide plate 2, which comprises a second guide plate body 22 and a plurality of brush hairs 21 vertically arranged on the working plate surface of the second guide plate body 22.

[0039] The brush hair 21 has a small friction with the strip steel, which can reduce or even avoid the scratch on the contacted strip steel head and tail section.

[0040] Preferably, the brush hair 21 is made of carbon fiber, which has a small friction coefficient and a large rigidity, can reliably support the strip steel and prevent the strip steel from being scratched. Further, a plurality of brush hairs 21 are twisted into a brush hair strand, and a plurality of brush hair strands are twisted into a brush hair column, which can increase the rigidity of the brush hair 21, and a plurality of brush hair columns arranged on the second guide plate body 22 can reliably support the strip steel.

[0041] Wherein, the brush hair 21 is fixedly installed on the second guide plate body 22.

[0042] Further, the brush hair columns are arranged at intervals, and the second guide plate body 22 is provided with blowing holes 23, that is, the blowing holes 23 are distributed between the brush hair columns, and the blowing holes 23 can remove the dirt falling on the second guide plate body 22 and adhering to the brush hair 21, further reducing the factors of scratching the strip steel.

[0043] Optionally, as shown in Figure 8A plurality of bristle planting areas 20 are arranged along the width direction of the second guide plate body 22 in sequence and at intervals, and the bristle planting areas 20 are preferably arranged along the length direction of the second guide plate body 22. In this way, the weight and cost of the bristle planting guide plate 2 can be reduced, and the contact area between the bristles 21 and the strip can be reduced, thereby further preventing the strip from being scratched.

[0044] In one embodiment, as shown in Figures 9-11 , the upstream side and the downstream side of the bristle planting guide plate 2 are adjacent to the roller guide plate 1, which can be the aforementioned roller guide plate 1, and the specific structure is not described here. The rolling of the conveying roller 11 can make the strip head smoothly enter the bristle planting guide plate 2 and prevent the strip head from being cut by the bristles 21. When the downstream side of the roller guide plate 1 is provided with the roller guide plate 1 having the inclined conveying section 111, the strip head can also be smoothly guided to the downstream pinch unit. In this scheme, the second guide plate body 22 of the bristle planting guide plate 2 and the first guide plate body 12 of the roller guide plate 1 are preferably an integral structure, that is, the bristles 21 and the conveying roller 11 are arranged on the same guide plate body.

[0045] When the roller guide plate 1 is arranged between two adjacent bristle planting guide plates 2, the load bearing capacity of the bristles 21 can be reduced, thereby prolonging the service life of the bristles 21. Similarly, in this scheme, the second guide plate body 22 of the bristle planting guide plate 2 and the first guide plate body 12 of the roller guide plate 1 are preferably an integral structure, that is, the front bristle planting section, the conveying roller 11 section and the rear bristle planting section are arranged in sequence on the same guide plate body.

[0046] In one embodiment, at least part of the scratch-preventing guide plate is a phenolic laminated cloth plate. The phenolic laminated cloth plate has a small friction coefficient and can reduce the scratching of the strip. Preferably, the phenolic laminated cloth plate can be used in the sampling guide plate, the tail end waste cutting guide plate and other areas where the surface quality of the strip is not high.

[0047] In one embodiment, as shown in Figure 1 , at least part of the scratch-preventing guide plate is a magnetic belt 3. The strip is attracted to the belt by a magnet, the belt is driven by a motor, and the strip is conveyed over a long distance by the belt. The belt can also climb or swing. Since there is no relative movement between the strip and the belt, the strip can be prevented from being scratched. The aforementioned magnetic belt 3 includes but is not limited to an electromagnet.

[0048] In one embodiment, the strip processing system is used for processing automobile plates. In the production process of automobile plates, the galvanizing unit and the recoiling unit are the finished product production line, and the local unqualified strip is cut off without scratches. Scratch-preventing design is required at the inlet section and the outlet section of the galvanizing unit and the entire line of the recoiling unit. A typical scheme is as shown in Figure 1 :

[0049] The magnetic belt 3 is arranged between the uncoiler 41 and the entry pinch roll 42, and can deliver the strip to the entry pinch roll 42 without scratch;

[0050] The entry pinch roll 42 is preferably provided with an encoder and a frequency converter, and the linear speed of the roll is consistent with the speed of the strip through the frequency control system, and there is no relative movement trend to avoid scratching the strip;

[0051] The roller guide plate 1 is arranged between the entry pinch roll 42 and the straightening machine 43;

[0052] The roller guide plate 1 is arranged between the straightening machine 43 and the head and tail cutting shear 44;

[0053] The roller guide plate 1 is arranged between the head and tail cutting shear 44 and the deviation correction roll 45;

[0054] The roller guide plate 1 is arranged between the deviation correction roll 45 and the disc shear 46;

[0055] The roller guide plate 1 is arranged between the disc shear 46 and the adjacent intermediate pinch roll 47 downstream;

[0056] The hair guide plate 2 or the hair roller combination guide plate is arranged between the subsequent finished product section 48, the inspection table 49 and the slitting shear 50;

[0057] The magnetic belt 3 is used between the slitting shear 50 and the coiler 51;

[0058] The phenolic laminated cloth board is used in the waste channel of the head and tail cutting shear 44 and the slitting shear 50.

[0059] Based on the above arrangement, different guide plates are arranged in different sections according to local conditions, which can better protect the strip and significantly improve the surface quality of the strip.

[0060] The above only describes the preferred embodiments of the present application, and does not limit the present application, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the protection scope of the present application.
