Description

Technical Field

[0001] The invention relates to the technical field of double-cut shears, in particular to a waste output device for double-cut shears. Background Art

[0002] The coiling process in the entrance area of ​​the galvanizing unit is to lift the cold-hardened coil in the cold-rolled intermediate warehouse by a crane to the entrance stepping beam, and then send it to the uncoiler by the coiling trolley, and automatically coil it after measuring the width and diameter. After uncoiling, the strip enters the pinch roller straightening machine to straighten the head, and then enters the double shear for head and tail shearing. The tail of the previous coil and the head of the next coil are welded at the welding machine, and the joint part of the width change is cut into a crescent shape to reduce stress concentration and avoid strip breakage. Then the strip enters the cleaning section and undergoes alkali spraying, electrolytic cleaning, brushing and hot water rinsing in turn to remove the residual iron powder and oil on the surface of the strip. The outlet is equipped with hot air drying. The cleaned strip is the basis for obtaining high-quality coatings, and can also ensure that the strip runs stably, without slipping or scratching in the entrance looper. The entrance vertical looper can ensure that the downstream process can still run normally and continuously when changing coils or welding in the entrance section.

[0003] The double shear is an important equipment in the entrance section of the galvanizing unit. The double shear adopts a double-cut design, usually using concave and convex blade holders to cooperate with each other, and the upper and lower groups of four blades work simultaneously, which improves the shearing efficiency and accuracy. Compared with general shearing machines, the double shear can reduce the accumulation of errors when shearing steel coils. However, due to the special structure of the double shear, the concave blade holder is at the bottom, and the debris generated during shearing is easy to accumulate in the groove of the concave blade holder, causing wear and error of the blade.

[0004] When the hot-dip galvanized strip is produced at the entrance uncoiler, the quality of the head and tail of the steel strip is unstable. In order to ensure the welding quality of the welder, the tail of the current roll needs to be cut in advance to ensure that the tail of the current roll and the head of the next roll can be stably welded at the welder. The double shear at the entrance of the hot-dip galvanizing line is a device specially used to cut the head and tail of the strip, ensuring that the strip can be welded normally at the welder after the head and tail are cut. At the same time, the double shear cuts the plate strip left when the strip tail is swung into broken strip steel. The broken strip steel can be sold as an additional product of the production line after being packaged by professionals to generate economic benefits. Usually after the first knife shearing, the remaining strip tail is about 10m, and then the strip tail is "broken tail" processed, that is, the double shear is used to cut the remaining strip tail into 1m long steel plates.

[0005] When the double-cut shears are shearing, short steel plates of 100-200mm in length will be formed between the upper and lower sets of blades. These shorter scraps will be mixed with the longer scraps. Later, the staff will need to pick out the two lengths of steel plates for recycling. The long steel plates can be stamped into various parts, and the short steel plates can be used to make guardrails, guard plates and other products. Classified recycling increases the recycling value. However, if the accumulated steel plates are only picked and classified for recycling by manual labor, the number of steel plates accumulated on the production line is large, the weight of the steel plates is also large, and manual screening is time-consuming and labor-intensive. Summary of the invention

[0006] The purpose of the present invention is to provide a waste output device for a double shearing machine, aiming to solve the problem in the prior art that it is difficult to screen recyclable steel plates after the double shearing machine shears the strip steel.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A waste material output device for a double-cutting shearing machine comprises an upper knife frame, the vertical section of which is in an inverted "convex" shape, a lower knife frame is arranged directly below the upper knife frame, the lower knife frame comprises two knife-setting plates arranged opposite to each other, blades are arranged on opposite sides of the two knife-setting plates and on both sides of the protruding part of the lower knife frame, a belt conveyor is arranged below the lower knife frame, a plurality of guide rollers are horizontally arranged on one side of the lower knife frame, and the guide rollers away from the lower knife frame are higher than the guide rollers close to the lower knife frame;

[0009] The conveyor belt is provided with adjustment mechanisms for adjusting the position of materials on both sides of the conveyor belt, and the adjustment mechanism comprises a pushing rod horizontally arranged on one side of the conveyor belt, the pushing rod is opposite to the conveyor belt, and a fixing plate is vertically arranged on the side of the conveyor belt away from the pushing rod, and a pushing plate is arranged at one end of the pushing rod facing the conveyor belt, the pushing plate is hinged to the pushing rod, and the axial direction of the movement trajectory of the moving end of the pushing plate is parallel to the transmission direction of the conveyor belt, a torsion spring is arranged at the hinge between the pushing plate and the pushing rod, and an adjustment plate is also arranged on the side of the conveyor belt away from the pushing rod, the adjustment plate comprises four adjustment parts, the four adjustment parts are arranged in a cross shape, a plate placement groove is opened on the side of the adjustment part, a sensor is arranged in the plate placement groove, a rotating shaft is arranged at the bottom of the adjustment plate, and a lifting platform is arranged at the bottom of the rotating shaft;

[0010] A first black box is arranged on the side of the adjustment mechanism away from the lower tool holder, a first ultraviolet lamp is arranged on the top of the inner wall of the first black box, two long strip-shaped first conveying plates are arranged in the first black box, the two first conveying plates are arranged opposite to each other, movable grooves are opened on the two first conveying plates, movable plates are arranged in the movable grooves, both ends of the movable plates are hinged to the first conveying plates, torsion springs are arranged at the hinges between the movable plates and the first conveying plates, first conveying wheels are arranged on the opposite sides of the two first conveying plates and the opposite sides of the two movable plates, the axial direction of the motion trajectory of the moving end of the movable plate is parallel to the conveying direction of the first conveying wheel, a lower pressing plate is arranged at the bottom of the movable plate, a first blocking plate is arranged on the side of the first conveying plate away from the lower tool holder, a first lifting cylinder is arranged at the bottom of the first blocking plate, an electric push rod is also arranged on the first blocking plate, a screening conveyor belt is arranged below the first conveying wheel, a fluorescent sheet is arranged below the first conveying wheel, and a first camera is also arranged in the first black box.

[0011] Through the above technical solution, when the steel strip needs to undergo the "tail breaking" process, the upper knife holder moves downward, and two sets of blades shear the steel strip into thin steel plates. The steel plates on the side of the lower knife holder are longer, and the steel plates directly below the upper knife holder are shorter. The short steel plates fall from the middle of the two knife plates onto the belt conveyor, and the long steel plates fall onto the guide rollers and are guided to the belt conveyor by the guide rollers. After the short and long steel plates fall onto the belt conveyor, the push rod moves forward to push the steel plate to one side of the fixed plate. One side of the steel plate collides with the fixed plate, and the initial adjustment of the steel plate is completed. When the long steel plate is transmitted on the conveyor belt, since the four sides of the long steel plate are long, it will not enter the plate placement groove. , the sensor cannot be triggered. At this time, the lifting platform controls the adjustment plate to rise, and the long steel plate moves from under the adjustment plate to the next section; in the process of the short steel plate falling from the double-cut shear to the belt conveyor, it is easy to be skewed. Since the short steel plate has two sides that are shorter, if the short steel plate is in a horizontal state on the conveyor belt, one end of the short steel plate will be inserted into the plate placement slot, triggering the sensor. The sensor sends an electrical signal to the rotating shaft, and the rotating shaft controls the adjustment plate to rotate 90°, so that the short steel plate is separated from the belt conveyor and cannot enter the next process. If the short steel plate is in a vertical state on the conveyor belt, the side in contact with the plate placement slot is longer, and the end of the short steel plate cannot enter the plate placement slot. At this time, the lifting platform controls the adjustment plate to rise, and the long steel plate moves from the bottom of the adjustment plate to the next section; in the process of the short steel plate falling from the double-cut shear to the belt conveyor, it is easy to be skewed. Since the short steel plate has two sides that are shorter, if the short steel plate is in a horizontal state on the conveyor belt, one end of the short steel plate will be inserted into the plate placement slot, triggering the sensor. The sensor sends an electrical signal to the rotating shaft, and the rotating shaft controls the adjustment plate to rotate 90°, so that the short steel plate is separated from the belt conveyor and cannot enter the next process. The lowering platform controls the adjustment plate to rise, and the long steel plate moves from under the adjustment plate to the next work section. The long steel plate and the short steel plate are adjusted to the same width direction for transportation through the adjustment of the adjustment mechanism, which is convenient for detecting and screening the length of the steel plate in the subsequent work section; then the long steel plate and the short steel plate are conveyed to the first black box by the belt conveyor, and the steel plate falls on the first conveying wheel for transportation. At this time, the first lifting cylinder controls the first blocking plate to rise to block the position of the steel plate, and the first ultraviolet lamp is turned on to irradiate the steel plate. When the first ultraviolet lamp irradiates the long steel plate, the shadow of the long steel plate is longer, which covers and blocks the fluorescent sheet, and the fluorescent sheet does not emit light. At this time, the first blocking plate drops to the first height, and the long The steel plate is conveyed to the next work section under the action of the first conveyor wheel. When the first ultraviolet lamp irradiates the short steel plate, the shadow of the short steel plate is shorter and cannot cover the fluorescent sheet. The fluorescent sheet emits light. The first camera captures it and transmits a signal to the electric push rod. The electric push rod extends and the end is located directly above the lower pressure plate. Then the first blocking plate drops to the second height, pressing the lower pressure plate downward, and the two movable plates start to rotate. The short steel plate on the first conveyor wheel falls from between the two movable plates onto the screening conveyor belt and is transported to the short steel plate collection box for collection for subsequent recycling processing, thereby completing the screening of long steel plates and short steel plates. After the short steel plate falls, the movable plate is reset under the action of the torsion spring.

[0012] The present invention is further configured as follows: a flipping mechanism for turning over the material is provided on the side of the first black box away from the lower tool holder, a second black box is provided on the side of the flipping mechanism away from the first black box, a second ultraviolet lamp and a second camera are provided on the top of the inner wall of the second black box, two second long strip conveying plates are provided in the second black box, second conveying wheels are provided on the opposite sides of the two first conveying plates, a second blocking plate is provided on the side of the second conveying plate away from the first black box, and a second lifting cylinder is provided at the bottom of the second blocking plate.

[0013] Through the above technical scheme, while the steel plate is being inspected and screened for length in the first black box, the first ultraviolet lamp can also detect oil stains on the surface of the steel plate. When the first camera captures oil stains on the front of the steel plate, the staff can take out the steel plate for cleaning. The steel plate without oil stains on the front is turned over by the flip mechanism and enters the second black box. The second lifting cylinder controls the second blocking plate to rise to block the steel plate. Then the second ultraviolet lamp is turned on to detect oil stains on the turned over steel plate. When the second camera captures oil stains on the back of the steel plate, the staff can take out the steel plate for cleaning for subsequent processing. If there is no oil stain on both sides, the steel plate will be conveyed to the next work section by the second conveyor wheel.

[0014] The present invention is further configured as follows: a marking liquid nozzle is provided on the first baffle plate and the second baffle plate, a receiving cavity is provided inside the first baffle plate and the second baffle plate, a liquid storage box is provided inside the receiving cavity, the marking liquid nozzle is connected to the liquid storage box, and a liquid injection hole is provided on the first baffle plate and the second baffle plate, and the liquid injection hole is communicated with the interior of the liquid storage box.

[0015] Through the above technical scheme, the staff injects the marking liquid into the liquid storage box from the injection hole. When oil stains are detected on the front of the steel plate, the marking liquid nozzle on the first blocking plate sprays the marking liquid on the side of the steel plate. When the steel plate is turned over and oil stains are detected on the other side, the marking liquid nozzle on the second blocking plate sprays the marking liquid on the other side of the steel plate. The subsequent work section can judge which side of the steel plate has oil stains according to the position of the marking liquid. The marking liquid can be any liquid such as fluorescent liquid, washable pigment, etc.

[0016] The present invention is further configured as follows: a plurality of groups of conveying rollers are arranged on the side of the second baffle plate away from the second black box, two cleaning cylinders are arranged in sequence from top to bottom on the side of the conveying roller away from the second baffle plate, a plurality of cleaning holes are opened on the cleaning cylinder, a liquid inlet pipe and a solenoid valve are also arranged on the cleaning cylinder, a third camera is also arranged on both sides of the conveying roller, and a cleaning sponge is arranged on the outer wall of the cleaning cylinder.

[0017] Through the above technical scheme, the steel plate enters between multiple groups of conveyor rollers, and the conveyor rollers control the steel plate to move forward. When passing through the cleaning cylinder, the third camera shoots and judges the two sides of the steel plate. If one side of the steel plate is photographed to be coated with marking liquid, it means that one side of the steel plate corresponding to the side has oil stains. The corresponding solenoid valve is started by controlling the electric signal, and the cleaning liquid is injected into the cleaning cylinder. The cleaning liquid leaks out of the cleaning hole and is absorbed by the cleaning sponge to clean the side of the steel plate with oil stains. If the marking liquid is photographed on both sides, the electronic valves on the two cleaning cylinders are opened, and both sides are cleaned at the same time.

[0018] The present invention is further configured as follows: two mounting plates are vertically arranged on both sides of the cleaning cylinder, two pressure pieces are arranged between the two mounting plates from top to bottom, both ends of the pressure pieces are hinged to the mounting plates, the axial direction of the motion trajectory of the moving end of the pressure piece is parallel to the axial direction of the cleaning cylinder, the pressure piece is rotatably connected to the cleaning cylinder, and a torsion spring is arranged at the hinge between the pressure piece and the mounting plate.

[0019] Through the above technical scheme, the steel plate is clamped by the conveying roller and conveyed forward. When the steel plate enters between the two cleaning cylinders, the end of the steel plate contacts the pressure piece, the upper pressure piece rotates upward, and the cleaning cylinder on the pressure piece moves downward. The lower pressure piece rotates downward, and the cleaning cylinder on the pressure piece moves upward, clamping the steel plate at the same time, thereby enhancing the cleaning effect of the cleaning cylinder and the cleaning sponge on the steel plate.

[0020] The present invention is further configured as follows: a stacking plate is horizontally arranged on the side of the cleaning cylinder away from the second blocking plate, and two alignment plates are vertically arranged on the stacking plate, the two alignment plates are arranged in a "∟" shape, a pushing plate is arranged on one side of the stacking plate, the cross-section of the pushing plate is in the shape of "┐", a sliding groove is opened on the stacking plate, the sliding groove is a dovetail groove, a sliding block matching the sliding groove is arranged at the bottom of the pushing plate, a reset spring is arranged between the sliding block and the inner wall of the sliding groove, a pull rope is arranged on the pushing plate, a rope winding wheel is arranged on the end of the pull rope away from the pushing plate, one end of the pull rope is wound around the rope winding wheel, and the rope winding wheel is connected to one of the two cleaning cylinders through a coupling.

[0021] Through the above technical scheme, when the steel plate moves between the two cleaning cylinders, the friction force will drive the two cleaning cylinders to rotate, and the cleaning cylinders and the coupling will drive the rope wheel to rotate the rod, and the rope wheel will wind the pulley, and the sliding block will slide in the sliding groove, and the pushing plate will move away from the alignment plate, and the reset spring will be compressed. When the steel plate moves to the end and falls on the stacking plate from above, the pressure piece will reset under the action of the torsion spring, and the two cleaning cylinders will separate. The reset spring will push the sliding block and the pushing plate to slide along the sliding groove, and the pushing plate will push the steel plate in the direction of the alignment plate, so that the steel plates can be stacked neatly.

[0022] The present invention is further configured as follows: the flipping mechanism includes a horizontally arranged rotating shaft, and the axial direction of the rotating shaft is perpendicular to the conveying direction of the first conveying wheel, a plurality of rotating plates are radially arranged on the rotating shaft, and the plurality of rotating plates are grouped in pairs, and the angle between the two rotating plates in the same group is an acute angle.

[0023] Through the above technical solution, the steel plate enters between the two rotating plates in the same group under the action of the first transmission wheel, the rotating shaft starts to rotate, flips the steel plate 180°, completes the flip, and then enters the second black box.

[0024] It should be understood that the principles and structures for controlling the rotation of the belt conveyor, the first conveyor wheel, the second conveyor wheel, the screening conveyor belt, the conveyor roller, the rotating shaft, the rotating shaft and other mechanisms are common technologies in the field and will not be elaborated on here.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The technology of the present invention changes the concave lower knife holder in the prior art into two knife plates. The short steel plates generated in the process of strip tail breaking can fall directly from between the two knife plates onto the belt conveyor to enter the next process. At the same time, the debris generated during shearing will not stay on the lower knife holder and will not get stuck in the blade, thereby extending the service life of the blade.

[0027] 2. The technology of the present invention sets up a first black box and then uses a purple light to illuminate the surface of the steel plate. It can not only detect stains on the surface of the steel plate, but also judge the length of the steel plate by whether the length of the shadow of the steel plate can cover the fluorescent sheet. When detecting a long steel plate, the shadow of the long steel plate can cover the fluorescent sheet. The fluorescent sheet will not emit light in the shadow, and the movable plate will not move. After the long steel plate is detected, it will be transported to the next process for subsequent cleaning, stacking, stamping and other treatments, thereby increasing the recycling value of the long steel plate. When there is a short steel plate, the shadow of the short steel plate under light is too short to cover the fluorescent sheet. The fluorescent sheet is outside the shadow and glows after being irradiated by the ultraviolet lamp. After the first camera captures the glow of the fluorescent sheet, it sends an electrical signal to the electric push rod. The electric push rod extends, and when the first blocking plate descends, the movable plate is driven to rotate through the lower pressure plate, and the short steel plate falls onto the screening conveyor belt. The short steel plate is transported to a separate collection box for collection, which is convenient for the subsequent separate recycling of the short steel plate. The whole process does not require human intervention, and the judgment and screening are fully automatic, which saves manpower and has high screening efficiency.

[0028] 3. The technology of the present invention sets a marking liquid nozzle. When oil stains are detected on the front side of the steel plate, the marking liquid nozzle marks one side of the steel plate. After turning over, when oil stains are detected on the other side of the steel plate, the marking liquid nozzle marks the other side of the steel plate. Then, in the cleaning process, the side of the steel plate is photographed and judged by the third camera. The two marked side edges correspond to the two sides of the steel plate respectively, so as to judge whether there are oil stains on the two sides of the steel plate; when it is detected that one side of the steel plate is marked, the cleaning cylinder on the side of the steel plate corresponding to the marked side needs to clean the steel plate, then the control The solenoid valve of the corresponding cleaning cylinder is opened, and the cleaning liquid is transported into the cleaning cylinder. Only the side of the steel plate with oil stains is cleaned, and the side without oil stains does not need to be cleaned; when it is detected that the two sides of the steel plate are marked, the solenoid valves of the two cleaning cylinders are controlled to open at the same time, and both sides of the steel plate are cleaned at the same time; when it is detected that neither of the two sides of the steel plate is marked, the solenoid valve does not need to be opened; the steel plate is marked with marking liquid, so that it is possible to directly judge whether there is oil stain on the surface of the steel plate during the cleaning process, so that only the side with oil stains is cleaned, and the side without oil stains does not need to be cleaned, thereby saving cleaning costs.

[0029] 4. The technology of the present invention sets a pressure piece. When the steel plate passes between the two cleaning cylinders under the action of the conveying roller, the steel plate pushes the two pressure pieces to rotate, and the two cleaning cylinders move relative to each other, thereby clamping the steel plate, increasing the friction between the steel plate and the cleaning sponge, and enhancing the cleaning effect. At the same time, it can drive the cleaning cylinder to rotate, and the cleaning cylinder and the coupling drive the rope wheel to rotate the rod, and the rope wheel is wound around the pulley. The sliding block slides in the sliding groove, and the pushing plate moves away from the alignment plate. The reset spring is compressed. When the steel plate moves to the end and falls on the stacking plate from above, the pressure piece is reset under the action of the torsion spring, and the two cleaning cylinders are separated. The reset spring pushes the sliding block and the pushing plate to slide along the sliding groove, and the pushing plate pushes the steel plate in the direction of the alignment plate, so that the steel plates can be stacked neatly.

[0046] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The waste output device of the double shearing machine provided by the present invention is as follows: Figures 1 to 12 As shown, it includes an upper tool holder 1, the vertical section of which is in an inverted "convex" shape, a lower tool holder 2 is arranged directly below the upper tool holder 1, and the lower tool holder 2 includes two knife-setting plates 2a arranged opposite to each other, blades 3 are arranged on the opposite sides of the two knife-setting plates 2a and on both sides of the protruding part of the lower tool holder 2, a belt conveyor 4 is arranged below the lower tool holder 2, and a plurality of guide rollers 5 are horizontally arranged on one side of the lower tool holder 2, and the guide rollers 5 away from the lower tool holder 2 are higher than the guide rollers 5 close to the lower tool holder 2;

[0048] When the steel strip needs to undergo the "tail cutting" process, the upper tool holder 1 moves downward, and the two sets of blades 3 shear the steel strip into thin steel plates. The steel plates on the sides of the lower tool holder 2 are longer, and the steel plates directly below the upper tool holder 1 are shorter. The short steel plates fall from the middle of the two knife plates 2a onto the belt conveyor 4, and the long steel plates fall onto the guide rollers 5 and are guided by the guide rollers 5 onto the belt conveyor 4.

[0049] The belt conveyor 4 is provided with adjustment mechanisms 40 for adjusting the material position on both sides thereof, the adjustment mechanisms 40 comprising a push rod 40a horizontally arranged on one side of the belt conveyor 4, the push rod 40a facing the belt conveyor 4, a fixing plate 40b vertically arranged on the side of the belt conveyor 4 away from the push rod 40a, a push plate 40c is arranged at one end of the push rod 40a facing the belt conveyor 4, the push plate 40c is hinged to the push rod 40a, and the axial direction of the motion trajectory of the motion end of the push plate 40c is aligned with the direction of the axis of the motion trajectory of the belt conveyor 4. The conveying direction of the conveying belt 4 is parallel, and a torsion spring is arranged at the hinge of the pushing plate 40c and the pushing rod 40a. An adjustment plate 40d is also arranged on the side of the belt conveyor 4 away from the pushing rod 40a. The adjustment plate 40d includes four adjustment parts 40d1, and the four adjustment parts 40d1 are arranged in a cross shape. A plate placement groove 40d2 is opened on the side of the adjustment part 40d1, and a sensor 40d3 is arranged in the plate placement groove 40d2. A rotating shaft 40e is arranged at the bottom of the adjustment plate 40d, and a lifting platform 40f is arranged at the bottom of the rotating shaft 40e.

[0050] The short steel plate and the long steel plate fall on the belt conveyor 4, and the push rod 40a moves forward to push the steel plate to one side of the fixed plate 40b. One side of the steel plate conflicts with the fixed plate 40b, and the initial adjustment of the steel plate is completed. When the long steel plate is transmitted on the conveyor belt, since the four sides of the long steel plate are long, it will not enter the plate placement groove 40d2 and cannot trigger the sensor 40d3. At this time, the lifting platform 40f controls the adjustment plate 40d to rise, and the long steel plate moves from under the adjustment plate 40d to the next section. When the short steel plate is transmitted on the conveyor belt, since the short steel plate has two sides that are shorter, if the short steel plate is in a horizontal state on the conveyor belt, one end of the short steel plate will be inserted into the plate placement groove 40d2 , triggering sensor 40d3, sensor 40d3 sends an electrical signal to the rotating shaft 40e, and the rotating shaft 40e controls the adjustment plate 40d to rotate 90°, so that the short steel plate is separated from the belt conveyor 4 and cannot enter the next process. If the short steel plate is in a vertical state on the conveyor belt, the side in contact with the plate placement groove 40d2 is longer, and the end of the short steel plate cannot enter the plate placement groove 40d2. At this time, the lifting platform 40f controls the adjustment plate 40d to rise, and the long steel plate moves from under the adjustment plate 40d to the next work section.

[0053] The steel plate is conveyed to the first black box 6 by the belt conveyor 4 and falls on the first conveying wheel 10 for conveying. At this time, the first lifting cylinder 13 controls the first blocking plate 12 to rise to block the position of the steel plate. The first ultraviolet lamp 7 is turned on to irradiate the steel plate. When the first ultraviolet lamp 7 irradiates the long steel plate, the shadow of the long steel plate is long, covering and blocking the fluorescent sheet 16, and the fluorescent sheet 16 does not emit light.

One end of the electric push rod 14 is located directly above the lower pressure plate 11, and then the first blocking plate 12 drops to a second height, pressing the lower pressure plate 11 downward, and the two movable plates 9 start to rotate. The first conveying wheel 10 tilts accordingly, and the short steel plate on the first conveying wheel 10 falls from between the two movable plates 9 onto the screening conveyor belt 15 and is transported to the waste collection box for collection, thereby completing the screening of the long steel plates and the short steel plates. After the short steel plate falls, the movable plate 9 is reset under the action of the torsion spring. While the steel plate is being length-detected and screened in the first black box 6, the first ultraviolet lamp can also detect oil stains on the surface of the steel plate. When the first camera 17 captures oil stains on the front of the steel plate, the staff can take out the steel plate for cleaning. The steel plate without oil stains on the front is turned over by the flipping mechanism 39 and enters the second black box 18. The second lifting cylinder 24 controls the second blocking plate 23 to rise to block the steel plate, and then the second ultraviolet lamp 19 is turned on to detect oil stains on the turned over steel plate. When the second camera 20 captures oil stains on the back of the steel plate, the staff can take out the steel plate for cleaning. If there is no oil stain on both sides, the steel plate will be conveyed to the next work section by the second conveying wheel 22.

[0054] The first blocking plate 12 and the second blocking plate 23 are both provided with a marking liquid nozzle 25, and the first blocking plate 12 and the second blocking plate 23 are both provided with a accommodating chamber 26 inside, and a liquid storage box 27 is provided in the accommodating chamber 26, and the marking liquid nozzle 25 is connected to the liquid storage box 27, and the first blocking plate 12 and the second blocking plate 23 are both provided with a liquid injection hole 28, and the liquid injection hole 28 is communicated with the interior of the liquid storage box 27, and a plurality of groups of conveying rollers 29 are provided on the side of the second blocking plate 23 away from the second black box 18, and two cleaning cylinders 30 are sequentially provided from top to bottom on the side of the conveying roller 29 away from the second blocking plate 23, and a plurality of cleaning holes 30a are provided on the cleaning cylinder 30, and a liquid inlet pipe 30b and a solenoid valve 30c are also provided on the cleaning cylinder 30, and a third camera 31 is also provided on both sides of the conveying roller 29, and a third camera 31 is provided on the outer wall of the cleaning cylinder 30. A cleaning sponge 30d is provided, and a stacking plate 34 is horizontally provided on the side of the cleaning cylinder 30 away from the second blocking plate 23, and two alignment plates 35 are vertically provided on the stacking plate 34, and the two alignment plates 35 are arranged in a "∟" shape. A pushing plate 36 is provided on one side of the stacking plate 34, and the cross-section of the pushing plate 36 is in a "┐" shape. A sliding groove 34a is opened on the stacking plate 34, and the sliding groove 34a is a dovetail groove. A sliding block 36a that cooperates with the sliding groove 34a is provided at the bottom of the pushing plate 36, and a return spring is provided between the sliding block 36a and the inner wall of the sliding groove 34a. A pull rope 37 is provided on the pushing plate 36, and a rope pulley 38 is provided at one end of the pull rope 37 away from the pushing plate 36, and one end of the pull rope 37 is wound around the rope pulley 38, and the rope pulley 38 is connected to one of the two cleaning cylinders 30 through a coupling.

[0055] Through the above technical solution, the staff injects the marking liquid into the liquid storage box 27 from the injection hole 28. When oil stains are detected on the front of the steel plate, the marking liquid nozzle 25 on the first blocking plate 12 sprays the marking liquid on the side of the steel plate. When the steel plate is turned over and oil stains are detected on the other side, the marking liquid nozzle 25 of the second blocking plate 23 sprays the marking liquid on the other side of the steel plate. The subsequent process can determine which side of the steel plate has oil stains according to the position of the marking liquid. Then the steel plate enters between the multiple groups of conveying rollers 29. The steel plate is moved forward by the conveying roller 29, and the end of the steel plate contacts the counter-pressing piece 33. The upper counter-pressing piece 33 rotates upward, and the cleaning cylinder 30 on the counter-pressing piece 33 moves downward. The lower counter-pressing piece 33 rotates downward, and the cleaning cylinder 30 on the counter-pressing piece 33 moves upward, and the steel plate is clamped at the same time. At this time, the third camera 31 shoots and judges the two sides of the steel plate. If one side of the steel plate is photographed to be coated with marking liquid, it means that one side of the steel plate corresponding to the side has oil stains. The over-voltage signal controls the corresponding electromagnetic valve 30c to start, and the cleaning liquid is injected into the cleaning cylinder 30. The cleaning liquid leaks out from the cleaning hole 30a and is absorbed by the cleaning sponge 30d to clean the side of the steel plate with oil stains. If the marking liquid is photographed on both sides, the electronic valves on the two cleaning cylinders 30 are opened, and both sides are cleaned at the same time. When the steel plate moves between the two cleaning cylinders 30, the friction force will drive the two cleaning cylinders 30 to rotate, and the cleaning cylinder 30 and the coupling drive the rope pulley 38 to rotate the rod, and the rope pulley 38 rotates. The rope wheel 38 winds the pull rope 37, the sliding block 36a slides in the sliding groove 34a, the pushing plate 36 moves away from the alignment plate 35, the reset spring is compressed, and when the steel plate moves to the end and falls on the stacking plate 34 from above, the pressure piece 33 is reset under the action of the torsion spring, the two cleaning cylinders 30 are separated, and the reset spring pushes the sliding block 36a and the pushing plate 36 to slide along the sliding groove 34a, and the pushing plate 36 pushes the steel plate toward the alignment plate 35, so that the steel plates can be stacked neatly.

[0056] The complete workflow of this technical solution is as follows:

[0057] When the steel strip needs to undergo the "tail-chopping" process, the upper knife holder 1 moves downward, and the two sets of blades 3 shear the steel strip into thin steel plates. The steel plates on the side of the lower knife holder 2 are longer, and the steel plates directly below the upper knife holder 1 are shorter. The short steel plates fall from the middle of the two knife plates 2a onto the belt conveyor 4, and the long steel plates fall onto the guide rollers 5 and are guided to the belt conveyor 4 by the guide rollers 5. The adjustment mechanism 40 adjusts the directions of the long and short steel plates to be consistent, and then they are conveyed to the first black box 6 by the belt conveyor 4. The steel plates fall on the first conveying wheel 10 for conveyance. At this time, the first lifting cylinder 13 controls the first blocking plate 12 to rise, blocking the position of the steel plate, and the first ultraviolet lamp 7 is turned on to irradiate the steel plate. When the first ultraviolet lamp 7 irradiates the long steel plate, the shadow of the long steel plate is longer, and the fluorescent sheet 16 covers the blocking plate. The fluorescent sheet 16 will not emit light. At this time, the first blocking plate 12 drops to the first height. The long steel plate is transmitted to the next section under the action of the first conveying wheel 10. When the first ultraviolet lamp 7 irradiates the short steel plate, the shadow of the short steel plate is short and cannot cover the fluorescent sheet 16. The fluorescent sheet 16 emits light. The first camera 17 captures it and transmits a signal to the electric push rod 14. The electric push rod 14 extends and the end is located directly above the lower pressing plate 11. Then the first blocking plate 12 drops to the second height, pressing the lower pressing plate 11 downward, and the two movable plates 9 start to rotate. The short steel plate on the first conveying wheel 10 falls from between the two movable plates 9 onto the screening conveyor belt 15 and is transported to the waste collection box for collection, thereby completing the screening of the long steel plate and the short steel plate. After the short steel plate falls, the movable plate 9 is reset under the action of the torsion spring;

[0058] While the steel plate is being length-detected and screened in the first black box 6, the first ultraviolet lamp can also detect oil stains on the surface of the steel plate. When the first camera 17 captures oil stains on the front of the steel plate, the marking liquid nozzle 25 on the first blocking plate 12 sprays marking liquid on the side of the steel plate. The steel plate without oil stains on the front enters between the two rotating plates 39b of the same group under the action of the first conveying wheel 10, and the rotating shaft 39a starts to rotate, turning the steel plate 180°, completing the turning over, and entering the second black box 18. The second lifting cylinder 24 controls the second blocking plate 23 to rise to block the steel plate, and then the second ultraviolet lamp 19 is turned on to detect oil stains on the turned over of the steel plate. When the second camera 20 captures oil stains on the back of the steel plate, the marking liquid nozzle 25 of the second blocking plate 23 sprays marking liquid on the other side of the steel plate. If there are no oil stains on both sides, the steel plate will not be marked and directly sent to the next section.

[0059] The steel plate enters between the multiple groups of conveying rollers 29, which control the steel plate to move forward. The end of the steel plate contacts the counter-pressure piece 33, and the upper counter-pressure piece 33 rotates upward. The cleaning cylinder 30 on the counter-pressure piece 33 moves downward. The lower counter-pressure piece 33 rotates downward, and the cleaning cylinder 30 on the counter-pressure piece 33 moves upward, clamping the steel plate at the same time. The third camera 31 shoots and judges the two side edges of the steel plate. If one side of the steel plate is photographed to be coated with marking liquid, it means that one side of the steel plate corresponding to the side has oil stains. The corresponding solenoid valve 30c is started by controlling the electric signal, and the cleaning liquid is injected into the cleaning cylinder 30. The cleaning liquid leaks from the cleaning hole 30a and is absorbed by the cleaning sponge 30d. The side of the steel plate with oil stains is cleaned. If both sides are photographed Marking liquid, the electronic valves on the two cleaning cylinders 30 are opened, and both sides are cleaned at the same time. At the same time, when the steel plate moves between the two cleaning cylinders 30, the friction force will drive the two cleaning cylinders 30 to rotate, and the cleaning cylinders 30 and the coupling drive the rope wheel 38 to rotate the rod, and the rope wheel 38 winds the pull rope 37, and the sliding block 36a slides in the sliding groove 34a, and the pushing plate 36 moves away from the alignment plate 35, and the reset spring is compressed. When the steel plate moves to the end and falls on the stacking plate 34 from above, the pressure piece 33 is reset under the action of the torsion spring, and the two cleaning cylinders 30 are separated. The reset spring pushes the sliding block 36a and the pushing plate 36 to slide along the sliding groove 34a, and the pushing plate 36 pushes the steel plate in the direction of the alignment plate 35, so that the steel plates can be stacked neatly.
