Abstract
Description
Technical Field
[0001] This invention relates to the field of strip steel processing technology, and in particular to a strip steel tension leveling and cross-cutting device. Background Technology
[0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of different industrial sectors for the industrialized production of various metal or mechanical products. Strip steel is generally supplied in coils and has advantages such as high dimensional accuracy, good surface quality, easy processing, and material saving.
[0003] Cross-cutting of strip steel is one of the most common and conventional methods of strip steel processing. It involves continuously stretching the coiled strip steel and then cutting it into equally spaced strip steel sheets. This process requires the cooperation of various structures to complete.
[0004] Traditional strip steel cross-cutting equipment typically just continuously feeds the strip steel to the bottom of the cutting blade before cross-cutting. However, the strip steel is prone to tilting during the feeding process, which not only results in uneven cuts after cross-cutting but also causes a chain reaction, leading to problems in subsequent strip steel cutting and reducing the quality of the finished product. Summary of the Invention
[0005] Therefore, the technical problem to be solved by the present invention is to overcome the fact that in the prior art, the strip steel is prone to tilting during the conveying process, which not only leads to uneven cuts of the strip steel after cross-cutting, but also causes a chain reaction, resulting in problems with subsequent strip steel cutting and reducing the quality of the finished product.
[0006] To solve the above-mentioned technical problems, the present invention provides a strip steel tensioning and cross-cutting device, comprising: a straightening box for straightening the bending of the strip steel surface; a detection table disposed at the output end of the straightening box for detecting the transport path of the strip steel; a first transmission table disposed behind the detection table for pulling and transporting the strip steel, receiving and correcting the transport path of the strip steel according to the detection information of the detection table; a cross-cutting table disposed behind the first transmission table for cross-cutting the strip steel into equidistant strip steel sheets; and a recycling box disposed below the output end of the cross-cutting table.
[0007] By setting up an inspection station, the strip steel is fed into the straightening box from the input end. The straightening box straightens the strip steel, correcting any bends and wrinkles on its surface to a flat state. The strip steel then passes through the straightening box and the inspection station, which detects whether the strip steel maintains its original neatness during its forward movement. When a deviation is detected during transport, the information is transmitted to the first transfer station. The first transfer station not only corrects the transport deviation but also pulls the strip steel, transporting it to the cross-cutting station. The flat strip steel then passes through the cross-cutting station and is stably cut to produce steel sheets of equal length. The cut steel sheets are received by the recycling box, completing the manufacturing process. This setup effectively improves the quality of the cross-cut products and ensures the stability of the strip steel's transport during the cross-cutting process.
[0008] In one embodiment of the present invention, the straightening box includes: a support base, two support bases arranged in parallel, the middle of the support base being hollow; an upper movable base, the two sides of the upper movable base being connected to the two support bases; a lower fixed cover, the two ends of the lower fixed cover being fixedly connected to the inner walls of the two support bases; a plurality of extrusion rollers, the plurality of extrusion rollers being divided into two groups, the two groups of extrusion rollers being arranged vertically with a gap between the two groups of extrusion rollers, the plurality of extrusion rollers in each group being equidistantly arranged; and a driving assembly, the driving assembly being disposed on one side of the extrusion rollers, the driving assembly being used to drive the plurality of extrusion rollers. The extrusion rollers rotate, supporting the upper moving seat and the lower fixed cover via a support base. The strip steel passes through the middle of multiple extrusion rollers, and multiple extrusion tubes operate synchronously, continuously extruding the strip steel as it enters. Utilizing the "Bauschinger effect" of the material, the strip steel is repeatedly bent multiple times. The extrusion effect gradually weakens from the inlet to the outlet end, causing multiple original curvatures to gradually become a single curvature. After passing through the last two extrusion rollers, the wrinkles on the surface of the strip steel are removed, ensuring the flatness of the strip steel surface, thereby further ensuring the quality of the finished strip steel sheets prepared by subsequent cutting.
[0009] In one embodiment of the present invention, the drive assembly includes: a geared motor, two geared motors respectively fixedly connected to an upper movable seat and a lower fixed cover; a gear ring, two gear rings fixedly connected to one end of the outer side of the extrusion roller, with the gear rings installed on the same end of each extrusion roller; a gear, the gear being installed at the output end of the geared motor; and a transmission chain, multiple transmission chains sleeved on the outer side of the gear rings for simultaneously driving multiple extrusion rollers to rotate synchronously, with adjacent transmission chains staggered from each other; the transmission chain is also sleeved on the outer side of the gear and gear ring for transmission. Power is transmitted to one or two extrusion rollers via the transmission chain through the rotation of the geared motor gear, and the extrusion rollers then transmit power to other extrusion rollers via the transmission chain, ensuring synchronous rotation of the extrusion rollers in the same row. This effectively extrudes and transports the strip steel. With this arrangement, multiple transmission chains cooperate with each other, and short-distance transmission chains do not experience tooth skipping, ensuring the stability of power transmission.
[0010] In one embodiment of the present invention, the cross-cutting table includes: hydraulic rods 2, four hydraulic rods 2 are divided into two groups, each group including two hydraulic rods 2 arranged in parallel, the two groups of hydraulic rods 2 are arranged in parallel; a fixed seat, the two ends of the fixed seat are fixedly connected to the top of two hydraulic rods 2 in one group, the bottom of the fixed seat is flat; a pressure receiving table, the pressure receiving table is disposed below the fixed seat; a gate, the gate is disposed on one side of the fixed seat, the two ends of the gate are fixedly connected to the top of two hydraulic rods 2 in the other group. When the strip steel is transported to the cross-cutting table, the bottom of the strip steel will adhere to the pressure receiving table, and then the strip steel will continue to be pushed forward by the first transmission table. After being pushed out to a predetermined length, the two hydraulic rods 2 first drive the fixed seat to press down and hold the strip steel, and then the other two hydraulic rods 2 drive the gate to press down and cut the strip steel. The surface of the pressure receiving table is provided with a cutting groove for the gate to pass through. After that, the cut strip steel sheet will fall into the recycling box, completing the processing process.
[0011] In one embodiment of the present invention, the detection table includes: a conveyor belt disposed at the output end of the straightening box, with the top surface of the conveyor belt flush with the output port of the straightening box; two electrically operated telescopic rods symmetrically arranged, their bottoms fixedly connected by a bracket, and the electric telescopic rods positioned above the conveyor belt; a displacement sensor fixedly connected to the moving end of the electric telescopic rod, the displacement sensor shortening under pressure and transmitting the pressure information outward, and returning to its original position via a built-in spring after the pressure is removed; and a contact plate fixedly connected to the end of the displacement sensor, the bottom of the contact plate abutting against the top surface of the conveyor belt. The straightened strip will first contact the conveyor belt. At the start of processing, it is necessary to first... The end of the strip is manually connected to the first transmission table. When the first transmission table is in operation, fully automatic processing is achieved. The distance between the two contact plates is the same as the width of the strip. When the strip moves between the two contact plates, it proves that the strip has not deviated during the transportation process. When the strip deviates, it will squeeze one of the contact plates, causing the displacement sensor to contract, thereby determining the direction of the deviation. This information is then transmitted to the first transmission table, which adjusts the pulling direction to return the strip to its original position. The two electric telescopic rods can adjust the distance between the two contact plates to accommodate different strips. At the same time, since the detection process is ongoing, there will be no problem of large-angle deviation of the strip, further ensuring the cutting quality of the strip.
[0012] In one embodiment of the present invention, the first transmission platform includes: two electric rollers arranged vertically with a gap between them; two hydraulic rods disposed between the ends of the two electric rollers for controlling the gap between them; a servo motor disposed below the two electric rollers for receiving signals from a displacement sensor and controlling the rotation angle of the first transmission platform; and a second transmission platform disposed at the entrance end of the cross-cutting platform. The second transmission platform lacks the servo motor compared to the first transmission platform. The two electric rollers clamp the strip steel, and the rollers rotate to pull the strip steel for movement. When a strip steel offset signal is received, the servo motor drives the two electric rollers to rotate as a whole. For example, if the strip steel offsets to the left, the electric rollers are adjusted to rotate slightly to the right, thus allowing the subsequent strip steel to return to its original position. The hydraulic rods control the gap between the two electric rollers, facilitating the entry and exit of the strip steel.
[0013] In one embodiment of the present invention, the straightening box further includes: a fixed spring seat, two symmetrically arranged fixed spring seats fixedly connected between the upper movable seat and the support seat; the fixed spring seat includes two vertically symmetrically arranged connecting plates; a telescopic sleeve, the telescopic sleeve fixedly connected between the two connecting plates; and a vertical spring, the vertical spring fixedly connected between the two connecting plates and sleeved on the outside of the telescopic sleeve. Because different strips have different strengths, hardnesses, and other properties, when encountering strips with higher hardness, the forceful compression can easily damage the strip and the compression rollers. By setting the fixed spring seats, when the strip enters the straightening box, the mass of the multiple compression rollers above will press against the strip. When the strip has high hardness, it will push against the entire upper movable seat, deforming the vertical spring. This prevents excessive compression that could damage the compression rollers. Combined with the repeated compression of multiple compression rollers, the surface of the exiting strip can also be ensured to be flat.
[0014] In one embodiment of the present invention, the straightening box further includes: an adjusting spring seat, the adjusting spring seat being based on a fixed spring seat, with a mating sleeve installed on the top of the upper connecting plate and a mating sleeve installed on the bottom of the lower connecting plate, the two mating sleeves being arranged perpendicularly to each other; a drive motor, multiple drive motors being fixedly connected in a support base, the output end of the drive motor being fixedly connected to the mating sleeve located above; a connecting groove, multiple connecting grooves being formed on the top surface of the upper movable seat, and the multiple connecting grooves being adapted to the bottom of multiple adjusting spring seats; and a hydraulic rod, multiple hydraulic rods being fixedly connected in the upper movable seat, and the hydraulic rods... The output end of the upper moving seat is located in the connecting groove; the two sides of the upper moving seat are slidably engaged with the two support seats. In order to improve the applicability of the straightening box, multiple adjusting spring seats are added. The adjusting spring seats are driven by the drive motor to rotate from horizontal to vertical, so that the bottom docking sleeve slides into the connecting groove. The hydraulic rod pushes out and docks with the bottom docking sleeve, which increases the force required to push the upper moving seat upward. In this way, the force of squeezing the strip can be adjusted when straightening different strips, so that the equipment can be used for more types of strips. It should be noted that the multiple adjusting spring seats need to be driven synchronously in groups to ensure the force balance of the upper moving seat.
[0015] In one embodiment of the present invention, a lead screw and nut mechanism is disposed above the recycling bin and is inclined; a gripping plate is fixedly connected to the moving end of the lead screw and nut mechanism, and the bottom surface of the gripping plate is horizontal. The bottom of the gripping plate is made of magnetic material. The traditional method of directly pushing the strip steel outward can easily cause the strip steel to bend, leading to problems in the cutting process. By using the lead screw and nut mechanism to drive the inclined gripping plate to move, the bottom of the gripping plate is made to fit against the top surface of the strip steel. With the help of the magnet, the strip steel is attracted and then pulled out. This ensures the cutting quality of the strip steel without bending it. The inclined setting of the lead screw and nut mechanism allows the strip steel to be moved at an angle upward, so that both the fixing and cutting processes provide a downward pulling force to the strip steel, causing the other end of the strip steel to detach from the gripping plate. When the strip steel material is not magnetically attractive, a negative pressure adsorption structure can be installed at the bottom of the gripping plate to complete this operation.
[0016] In one embodiment of the present invention, the recycling bin consists of two parcel boxes that slide and engage with each other, one of which is fixedly connected to two hydraulic rods; two electric telescopic rods are fixedly connected to the outside of the hydraulic rods, and the moving end of the electric telescopic rod is fixedly connected to the other parcel box. The electric telescopic rod can move the parcel box outward, thereby expanding the bottom area of the recycling bin and accommodating steel strips of different lengths.
[0017] The technical solution of the present invention has the following advantages over the prior art:
[0018] The present invention discloses a strip steel straightening and cross-cutting device. Through the setting of a detection table, strip steel is fed from the input end of a straightening box. The straightening box straightens the strip steel, correcting the bending and wrinkles on its surface to a flat state. The strip steel then passes through the straightening box and through the detection table, which detects whether the strip steel maintains its original straightness during its forward movement. When a deviation is detected during the transport of the strip steel, the information is transmitted to a first transmission table. The first transmission table not only corrects the transport deviation of the strip steel but also pulls the strip steel, transporting it to the cross-cutting table. The flat strip steel then passes through the cross-cutting table and is stably cut to produce steel sheets of the same length. The cut steel sheets are received by a recycling box, completing the preparation process. This setup effectively improves the quality of the cross-cut products and ensures the transport stability of the strip steel during the cross-cutting process.
[0019] The upper moving seat and lower fixed cover are supported by the support base. The strip steel passes through the middle of multiple extrusion rollers. Multiple extrusion tubes operate synchronously and continuously extrude the strip steel entering them. The "Bauschinger effect" of the material is used to repeatedly bend the plate. The extrusion effect gradually weakens from the inlet end to the outlet end, so that multiple original curvatures are gradually transformed into a single curvature. After passing through the last two extrusion rollers, the wrinkles on the surface of the strip steel can be removed to ensure the flatness of the strip steel surface, thereby further ensuring the quality of the finished strip steel sheet produced by subsequent cutting.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.
[0031] Reference Figures 1 to 5 As shown, a strip steel straightening and cross-cutting device of the present invention includes: a straightening box 1, which is used to straighten the bends on the surface of the strip steel; a detection table 2, which is disposed at the output end of the straightening box 1 and is used to detect the transport path of the strip steel; a first transmission table 4, which is disposed behind the detection table 2 and is used to pull and transport the strip steel, receive and correct the transport path of the strip steel according to the detection information of the detection table 2; a cross-cutting table 6, which is disposed behind the first transmission table 4 and is used to cross-cut the strip steel into equidistant strip steel sheets; and a recycling box 8, which is disposed below the output end of the cross-cutting table 6.
[0032] During operation, traditional strip steel cross-cutting equipment generally just continuously feeds the strip steel to the bottom of the cutting blade and then performs cross-cutting. However, the strip steel is prone to tilting during the feeding process, which not only results in uneven cuts after cross-cutting, but also causes a chain reaction, causing problems in subsequent strip steel cutting and reducing the quality of the finished product.
[0033] With the setting of the inspection station 2, the strip steel is fed into the input end of the straightening box 1. The straightening box 1 straightens the strip steel, correcting the bending and wrinkles on the surface of the strip steel to a flat state. Then the strip steel passes through the straightening box 1 and passes through the inspection station 2. The inspection station 2 can detect whether the strip steel maintains its original neat state during the forward movement. When the strip steel is detected to have deviated during transportation, the information is transmitted to the first transmission station 4. The first transmission station 4 is not only used to correct the transportation deviation of the strip steel, but also to pull the strip steel and transport it to the cross-cutting station 6. Then the flat strip steel passes through the cross-cutting station 6 and is stably cut by the cross-cutting station 6 to produce steel sheets of the same length. The cut steel sheets are received by the recycling box 8, completing the preparation process. Through this setting, the quality of the cross-cut product is effectively improved and the transportation stability of the strip steel during the cross-cutting process is guaranteed.
[0034] Reference Figures 1 to 5 As shown, the straightening box 1 includes: a support base 9, two support bases 9 arranged in parallel, the middle of the support base 9 being hollow; an upper movable base 11, the two sides of the upper movable base 11 being connected to the two support bases 9; a lower fixed cover 12, the two ends of the lower fixed cover 12 being fixedly connected to the inner walls of the two support bases 9; a plurality of extrusion rollers 15, the plurality of extrusion rollers 15 being divided into two groups, the two groups of extrusion rollers 15 being arranged vertically, with a gap between the two groups of extrusion rollers 15, the plurality of extrusion rollers 15 in each group being equidistantly arranged; and a drive assembly, the drive assembly being disposed on one side of the extrusion rollers 15, the drive assembly being used to drive the plurality of extrusion rollers 15 to rotate.
[0035] During operation, the upper movable seat 11 and the lower fixed cover 12 are supported by the support seat 9. The strip passes through the middle of multiple extrusion rollers 15. Multiple extrusion tubes 15 operate synchronously, continuously extruding the strip that enters them. The material is repeatedly bent by the "Bauschinger effect". The extrusion effect gradually weakens from the inlet end to the outlet end, so that multiple original curvatures are gradually transformed into a single curvature. After passing through the last two extrusion rollers 15, the wrinkles on the surface of the strip can be removed, ensuring the flatness of the strip surface, thereby further ensuring the quality of the finished strip sheet produced by subsequent cutting.
[0036] Reference Figures 1 to 5 As shown, the drive assembly includes: a reduction motor 16, two reduction motors 16 being fixedly connected to the upper movable seat 11 and the lower fixed cover 12 respectively; a gear ring 17, two gear rings 17 being fixedly connected to one end of the outer side of the extrusion roller 15, with the gear rings 17 mounted on the same end of each extrusion roller 15; a gear, the gear being mounted on the output end of the reduction motor 16; and a transmission chain 18, multiple transmission chains 18 being sleeved on the outer side of the gear rings 17 for simultaneously driving multiple extrusion rollers 15 to rotate synchronously, with adjacent transmission chains 18 being staggered; the transmission chains 18 are also sleeved on the outer side of the gears and gear rings 17 for transmission.
[0037] During operation, the geared motor 16 rotates, and the power is transmitted to one or two extrusion rollers 15 through the transmission chain 18. The extrusion rollers 15 then transmit the power to other extrusion rollers 15 through the transmission chain 18, ensuring the synchronous rotation of the extrusion rollers in the same row. This effectively extrudes and transports the strip steel. With this setup, multiple transmission chains 18 cooperate with each other, and the short-distance transmission of the transmission chains 18 will not cause the problem of skipping teeth, thus ensuring the stability of power transmission.
[0038] Reference Figures 1 to 7 As shown, the cross-cutting platform 6 includes: hydraulic rods 29, four hydraulic rods 29 are divided into two groups, each group including two hydraulic rods 29 arranged in parallel, the two groups of hydraulic rods 29 are arranged in parallel; a fixed base 30, the two ends of the fixed base 30 are fixedly connected to the top of two hydraulic rods 29 in one group, the bottom of the fixed base 30 is flat; a pressure receiving platform 32, the pressure receiving platform 32 is disposed below the fixed base 30; a gate 31, the gate 31 is disposed on one side of the fixed base 30, the two ends of the gate 31 are fixedly connected to the top of two hydraulic rods 29 in the other group;
[0039] During operation, when the strip is transported to the cross-cutting table 6, the bottom of the strip will adhere to the pressure table 32. Then, the strip continues to be pushed forward by the first transfer table 4. After being pushed out to a predetermined length, the two hydraulic rods 29 drive the fixed seat 30 to press down and hold the strip in place. Then, the other two hydraulic rods 29 drive the gate 31 to press down and cut the strip. The surface of the pressure table 32 has a cutting groove for the gate 31 to pass through. After that, the cut strip will fall into the recycling box 8, completing the processing.
[0040] Reference Figures 1 to 7 As shown, the testing platform 2 includes: a conveyor belt 3, which is located at the output end of the straightening box 1, and the top surface of the conveyor belt 3 is flush with the output port of the straightening box 1; two electric telescopic rods 24, which are symmetrically arranged, and the bottom of the two electric telescopic rods 24 are fixedly connected by a bracket, and the electric telescopic rods 24 are located above the conveyor belt 3; a displacement sensor 26, which is fixedly connected to the moving end of the electric telescopic rod 24, and the displacement sensor 26 will shorten under pressure and transmit the pressure information outward, and return to its original position by a built-in spring after the pressure is removed; and a contact plate 25, which is fixedly connected to the end of the displacement sensor 26, and the bottom of the contact plate 25 is in contact with the top surface of the conveyor belt 3.
[0041] During operation, the straightened strip first contacts the conveyor belt 3. At the start of processing, the end of the strip needs to be manually connected to the first transmission table 4. When the first transmission table 4 operates, fully automatic processing is achieved. The distance between the two contact plates 25 is the same as the width of the strip. When the strip moves between the two contact plates 25, it indicates that there is no deviation during transport. If deviation occurs, the strip will press against one of the contact plates 25, causing the displacement sensor 26 to contract, thus determining the direction of deviation. This information is then transmitted to the first transmission table 4, which adjusts the pulling direction to return the strip to its original position. Two electric telescopic rods 24 can adjust the distance between the two contact plates 25 to accommodate different strips. Since the detection process is continuous, large-angle deviations of the strip are prevented, further ensuring the cutting quality of the strip.
[0042] Reference Figures 1 to 7 As shown, the first transmission platform 4 includes: two electric rollers arranged vertically with a gap between them; two hydraulic rods arranged between the ends of the two electric rollers to control the gap between them; a servo motor 28 located below the two electric rollers, which receives signals from the displacement sensor 26 and controls the rotation angle of the first transmission platform 4; and a second transmission platform 5 located at the entrance of the cross-cutting platform 6, which lacks the servo motor 28 compared to the first transmission platform 4.
[0043] During operation, two electric rollers clamp the strip steel and rotate to pull the strip steel to move it. When a strip steel offset signal is received, the servo motor 28 drives the two electric rollers to rotate as a whole. For example, if the strip steel offsets to the left, the electric rollers are adjusted to rotate slightly to the right, so that the subsequent strip steel can be returned to its original position. The hydraulic rod 3 controls the distance between the two electric rollers to facilitate the entry and exit of the strip steel.
[0044] Reference Figures 1 to 7 As shown, the straightening box 1 further includes: a fixed spring seat 10, two symmetrically arranged fixed spring seats 10 fixedly connected between the upper movable seat 11 and the support seat 9; the fixed spring seat 10 includes two vertically symmetrically arranged connecting plates 19; a telescopic sleeve 22, the telescopic sleeve 22 fixedly connected between the two connecting plates 19; and a vertical spring 21, the vertical spring 21 fixedly connected between the two connecting plates 19, and the vertical spring 21 sleeved on the outside of the telescopic sleeve 22;
[0045] During operation, due to the different strengths, hardness, and other properties of different strips, when encountering strips with higher hardness, the strong compression of the strip can easily damage the strip and the compression rollers 15. By setting the fixed spring seat 10, when the strip enters the straightening box 1, the mass of the multiple compression rollers 15 above will compress the strip. When the strip has high hardness, it will push against the entire upper moving seat 11, causing the vertical spring 21 to deform. This will prevent excessive compression that could damage the compression rollers 15. With the repeated compression of multiple compression rollers 15, the surface of the strip at the exit can also be kept flat.
[0046] Reference Figures 1 to 7 As shown, the straightening box 1 further includes: an adjusting spring seat 13, which is based on the fixed spring seat 10, and has a docking sleeve 20 installed on the top of the upper connecting plate 19 and a docking sleeve 20 installed on the bottom of the lower connecting plate 19, with the two docking sleeves 20 arranged perpendicularly to each other; a drive motor, with multiple drive motors fixedly connected in the support seat 9, and the output end of the drive motor fixedly connected to the docking sleeve 20 located above; a connecting groove 14, with multiple connecting grooves 14 opened on the top surface of the upper moving seat 11, and the multiple connecting grooves 14 being adapted to the bottom of multiple adjusting spring seats 13; a hydraulic rod 23, with multiple hydraulic rods 23 fixedly connected in the upper moving seat 11, and the output end of the hydraulic rod 23 located in the connecting groove 14; the two sides of the upper moving seat 11 are slidably engaged with the two support seats 9;
[0047] During operation, in order to improve the applicability of the straightening box 1, multiple adjusting spring seats 13 are added. The adjusting spring seats 13 are driven by the drive motor to rotate from a horizontal to a vertical state, so that the bottom docking sleeve 20 slides into the connecting groove 14. The hydraulic rod 23 pushes out and docks with the bottom docking sleeve 20, which increases the force required to push the upper moving seat 11. This allows for adjustment of the squeezing force of the strip when straightening different strips, so that the equipment can be used for more types of strips. It should be noted that the multiple adjusting spring seats 13 need to be driven synchronously in groups to ensure the force balance of the upper moving seat 11.
[0048] Reference Figures 1 to 8 As shown, there is a lead screw and nut mechanism 7, which is located above the recycling bin 8 and is inclined; and a gripping plate 33, which is fixedly connected to the moving end of the lead screw and nut mechanism 7, with the bottom surface of the gripping plate 33 being horizontal and the bottom of the gripping plate 33 being made of magnetic material.
[0049] During operation, the traditional method of directly pushing the strip outwards can easily cause the strip to bend, leading to problems in the cutting process. By using the screw and nut mechanism 7 to drive the inclined gripping plate 33 to move, the bottom of the gripping plate 33 is brought into contact with the top surface of the strip. With the help of magnets, the strip is attracted and then pulled out. This ensures the cutting quality of the strip while preventing it from bending. The inclined setting of the screw and nut mechanism 7 causes the strip to move at an upward angle, providing a downward pulling force to the strip during both the fixing and cutting processes, allowing the other end of the strip to detach from the gripping plate 33. When the strip material is not magnetically pleasing, a negative pressure adsorption structure can be installed at the bottom of the gripping plate 33. This structure can be an electrically driven negative pressure suction cup to complete this operation.
[0050] Reference Figures 1 to 8 As shown, the recycling bin 8 consists of two parcel boxes that slide and engage with each other. One parcel box is fixedly connected to two hydraulic rods 29. Two electric telescopic rods 27 are fixedly connected to the outside of the hydraulic rods 29. The moving end of the electric telescopic rods 27 is fixedly connected to the other parcel box. During operation, the parcel box can be moved outward by the electric telescopic rods 27, which can expand the bottom area of the recycling bin 8 and accommodate steel strips of different lengths.
[0051] During operation, the strip steel is fed into the straightening box 1 from the input end through the detection table 2. The straightening box 1 straightens the strip steel, correcting the bending and wrinkles on the surface of the strip steel to a flat state. Then the strip steel passes through the straightening box 1 and through the detection table 2. The detection table 2 can detect whether the strip steel maintains its original neat state during the forward movement. When the strip steel is detected to have deviated during transportation, the information is transmitted to the first transmission table 4. The first transmission table 4 is not only used to correct the transportation deviation of the strip steel, but also to pull the strip steel and transport it to the cross-cutting table 6. Then the flat strip steel passes through the cross-cutting table 6 and is stably cut by the cross-cutting table 6 to produce steel sheets of the same length. The cut steel sheets are received by the recycling box 8 to complete the preparation process. Through this setting, the quality of the cross-cut product is effectively improved and the transportation stability of the strip steel during the cross-cutting process is guaranteed.
[0052] The upper movable seat 11 and the lower fixed cover 12 are supported by the support seat 9. The strip passes through the middle of multiple extrusion rollers 15. Multiple extrusion tubes 15 operate synchronously and continuously extrude the strip entering them. The material is repeatedly bent by the "Bauschinger effect". The extrusion effect gradually weakens from the inlet end to the outlet end, so that multiple original curvatures are gradually transformed into a single curvature. After passing through the last two extrusion rollers 15, the wrinkles on the surface of the strip can be removed to ensure the flatness of the strip surface, thereby further ensuring the quality of the finished strip sheet produced by subsequent cutting.
[0053] The power is transmitted to one or two extrusion rollers 15 through the rotation of the geared motor 16 and the transmission chain 18. The extrusion rollers 15 then transmit the power to other extrusion rollers 15 through the transmission chain 18, ensuring the synchronous rotation of the extrusion rollers in the same row. This can effectively extrude and transport the strip steel. With this configuration, multiple transmission chains 18 cooperate with each other, and the short-distance transmission of the transmission chains 18 will not cause the problem of skipping teeth, thus ensuring the stability of power transmission.
[0054] When the strip is transported to the cross-cutting table 6, the bottom of the strip will adhere to the pressure table 32. Then the strip continues to be pushed forward by the first transfer table 4. After being pushed out to a predetermined length, the two hydraulic rods 29 drive the fixed seat 30 to press down and hold the strip. Then the other two hydraulic rods 29 drive the gate 31 to press down and cut the strip. The surface of the pressure table 32 has a cutting groove for the gate 31 to pass through. After that, the cut strip will fall into the recycling box 8, completing the processing.
[0055] After being straightened, the strip steel will first contact the conveyor belt 3. When processing begins, the end of the strip steel needs to be manually connected to the first transmission table 4. When the first transmission table 4 is in operation, fully automatic processing is achieved. The distance between the two contact plates 25 is the same as the width of the strip steel. When the strip steel moves between the two contact plates 25, it proves that the strip steel has not deviated during the transportation process. When the strip steel deviates, the strip steel will squeeze one of the contact plates 25, causing the displacement sensor 26 to contract, thereby knowing which direction the strip steel deviated in. At this time, this information is transmitted to the first transmission table 4, and the first transmission table 4 adjusts the pulling direction to return the strip steel to its original position. The two electric telescopic rods 24 can adjust the distance between the two contact plates 25 to adapt to different strip steels. At the same time, since the detection process is ongoing, there will be no problem of large-angle deviation of the strip steel, further ensuring the cutting quality of the strip steel.
[0056] Two electric rollers clamp the strip steel. The electric rollers rotate and pull the strip steel to move it. When a strip steel offset signal is received, the servo motor 28 drives the two electric rollers to rotate as a whole. For example, if the strip steel offsets to the left, the electric rollers are adjusted to rotate slightly to the right so that the strip steel can return to its original position. The hydraulic rod three controls the distance between the two electric rollers to facilitate the entry and exit of the strip steel.
[0057] Because different strips have different strengths, hardness and other properties, when encountering strips with higher hardness, the strong extrusion of the strip can easily damage the strip and the extrusion rollers 15. By setting the fixed spring seat 10, when the strip enters the straightening box 1, the mass of the multiple extrusion rollers 15 above will press on the strip. When the strip has high hardness, it will push against the entire upper moving seat 11, causing the vertical spring 21 to deform. This will prevent the problem of excessive extrusion that could damage the extrusion rollers 15. With the repeated extrusion of multiple extrusion rollers 15, the surface of the strip at the exit can also be kept flat.
[0058] To improve the applicability of the straightening box 1, multiple adjusting spring seats 13 are added. The adjusting spring seats 13 are rotated from horizontal to vertical by the drive motor, allowing the bottom docking sleeve 20 to slide into the connecting groove 14. The hydraulic rod 23 pushes out and docks with the bottom docking sleeve 20, which increases the force required to push the upper moving seat 11. This allows for adjustment of the squeezing force on the strip when straightening different strips, so that the equipment can be used for more types of strips. It should be noted that the multiple adjusting spring seats 13 need to be driven synchronously in groups to ensure the force balance of the upper moving seat 11.
[0059] The traditional method of directly pushing the strip outwards can easily cause the strip to bend, leading to problems in the cutting process. By using the screw and nut mechanism 7 to drive the inclined gripping plate 33 to move, the bottom of the gripping plate 33 is made to fit against the top surface of the strip. With the help of magnets, the strip is attracted and then pulled out. This ensures the cutting quality of the strip while preventing it from bending. The inclined setting of the screw and nut mechanism 7 makes the strip move at an angle upwards, so that both the fixing and cutting processes provide downward pulling force to the strip, causing the other end of the strip to detach from the gripping plate 33. When the strip material is not magnetically attractive, a negative pressure adsorption structure can be installed at the bottom of the gripping plate 33 to complete this operation.
[0060] The electric telescopic rod 27 can move the package box outward, thus expanding the bottom area of the recycling box 8 to accommodate steel strips of different lengths.
[0061] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
