Description

Technical Field

[0001] This invention relates to the field of color-coated sheet slitting technology, and more particularly to a laser cutting device for color-coated rolls. Background Technology

[0002] Color-coated steel sheet is a composite material with an organic coating applied to the surface of a metal substrate (such as cold-rolled steel sheet or galvanized steel sheet). Before further processing, color-coated steel sheets are typically in roll form. Being thin and wide, they require slitting before further processing. This slitting is usually done using color-coated steel sheet cutting equipment, which includes a laser cutter with lateral movement capabilities to cut the coated edges. A transfer frame located below the laser cutter houses transfer rollers. After the color-coated steel sheet roll is released using an uncoiling and leveling device, it is transferred to the transfer frame as a flat sheet. As the flat sheet moves, it passes through the laser cutter's beam, resulting in slitting.

[0003] Currently, common color-coated steel sheet cutting equipment mainly includes two laser cutters. These two laser cutters can move laterally, and the two lateral laser cutters can cut the color-coated steel sheet into three sections. By adjusting the position of the two lateral laser cutters, the width of each of the three sections can be adjusted. The three sections of the cut sheet will be wound by three winding rollers at the front end of the conveyor frame. However, existing laser slitting equipment for color-coated steel sheets has shortcomings in use: it is extremely inconvenient to connect the three strips of color-coated steel sheet to the three winding rollers. The current method is to manually lift the front ends of the three strips so that the front ends of the three strips are attached to the outer wall of the corresponding winding rollers, and then fix the strips to the corresponding winding rollers. The color-coated steel sheet is continuously conveyed, and the three winding rollers are controlled to rotate synchronously to wind the three strips. Because the three strips are manually lifted and attached to the corresponding winding rollers, the strips are prone to skewing after they are attached to the winding rollers. This skewing makes it easy for the three strips to not fit together when they are wound. This state makes it easy for the color-coated steel sheet to shift laterally during transport. This lateral shift will directly affect the accuracy (width dimension) of the three strips after cutting.

[0004] Therefore, the present invention proposes a laser cutting device for color coated rolls. Summary of the Invention

The threaded sleeve and the lead screw are screwed together. A lead screw is provided in the left and right slides. A motor is fixedly connected to one end of the left and right slides. The output shaft of the motor is fixedly connected to one end of the lead screw. A threaded sleeve is fixedly connected to the top wall of the horizontal sleeve through a plate. The threaded sleeve and the lead screw are screwed together.

[0009] As a further description of the above technical solution: The bottom wall of the slotted frame is fixedly connected to two support rods, which are respectively close to the two sides.

A drive shaft is fixedly connected to one side of the U-shaped connecting frame at the free end. The actuating end of the lifting drive is fixedly connected to a connecting sleeve. A rotating sleeve is sleeved inside the connecting sleeve. The rotating sleeve is sleeved on the outside of the drive shaft and the two are axially slidingly engaged.

[0010] As a further description of the above technical solution: A gantry frame is fixedly connected above the transmission frame and located on the upper side behind the horizontal axis. A connecting seat is fixedly connected to the top of the gantry frame. A cantilever is fixedly connected to the front side of the connecting seat. Arm plates located at the adjacent ends of the other two winding rollers are fixedly connected to both sides of the cantilever. A rotating shaft is provided on the arm plate. A docking sleeve is fixedly connected to one end of the rotating shaft. The docking sleeve is inserted into one end of the roller shaft of the winding roller.

The two plates pushed upward will be pressed and adhered to the outer wall of the corresponding winding roller. At this time, when the winding roller and the plate it adheres to are fixedly connected, it can ensure that the winding roller tightly winds the corresponding plate, thereby avoiding the color-coated sheet from being tilted during transportation. This ensures the accuracy (width dimension) of the three plates after the color-coated sheet is cut.

[0015] 2. In this invention, by setting up a vertical shaft, left and right sliding frames, upper and lower sliding frames and connecting rods, the spacing and position of the two U-shaped connecting frames can be adjusted. This setting allows the corresponding plates to be pushed up without interference by the rollers when the width of the three plates cut from the color-coated sheet changes. This setting also ensures that the plates and winding rollers can be accurately wound when the equipment is cut into plates of different specifications.

[0016] 3. In this invention, by opening evenly distributed screw holes on the outer peripheral wall of the winding roller, after the three plates of the color-coated sheet are cut and attached to their respective winding rollers, the operator can use self-tapping screws in conjunction with the screw holes to fasten the plates and their respective corresponding winding rollers. This setting can greatly reduce the operation of fastening the plates and their respective corresponding winding rollers and make it more convenient. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-5A laser cutting device for color-coated steel rolls is disclosed. This device is applicable to intelligent welding systems involving metal cutting and welding equipment. Before spraying, the color-coated steel rolls need to be cut into shape using metal cutting equipment. After shaping, they are sprayed and then rolled up. After rolling up, they are transferred to a slitting device to cut the color-coated steel sheet into multiple strips. This device is used to slit the color-coated steel sheet, specifically by laser beam processing of the metal strips. It uses a laser beam emitted by a laser cutter 200 to continuously slit the color-coated steel sheet. After the color-coated steel rolls are slit on the slitting device, the head end of the supplementary color-coated steel roll is welded to the tail end of the previous color-coated steel sheet using welding equipment. In this technical solution, the cutting equipment includes a transmission frame 1, which is a horizontal gantry structure. The transmission frame 1 is equipped with a plate for transporting color-coated sheets. Specifically, the transmission frame 1 is equipped with a row of transmission rollers 180 for supporting the color-coated sheets. The two ends of the transmission rollers 180 are rotatably connected to the opposite side walls inside the transmission frame 1. That is to say, the uncoated color-coated sheet can be transported forward under the support of a row of transmission rollers 180. It should be noted that during use, the open end of the transmission frame 1 on this equipment is fixedly connected to a common color-coated roll unwinding and leveling device in the prior art. The function of the unwinding and leveling device is to transport the color-coated sheet in a flat state onto the transmission frame 1.

[0021] In this technical solution, a vertical shaft 2 is fixedly installed in the middle of the bottom of the transmission frame 1. Specifically, a base plate 21 is fixedly connected to the bottom of the vertical shaft 2, and a channel frame 11 is fixedly connected to the bottom of the transmission frame 1. The bottom of the channel frame 11 is fixedly connected to the bottom wall of the base plate 21, and both ends of the channel frame 11 are fixedly connected to the bottom walls of two parallel beams on the transmission frame 1. A horizontal shaft 3 is fixedly connected to the top of the vertical shaft 2. In specific implementation, the middle of the bottom wall of the horizontal shaft 3 is fixedly connected to the top of the vertical shaft 2.

[0022] A sliding sleeve 4 is fitted onto the horizontal shaft 3, and the sliding sleeve 4 and the horizontal shaft 3 are axially slidingly engaged. A rotating cylinder 5 is fitted onto the outside of the sliding sleeve 4, and the rotating cylinder 5 and the sliding sleeve 4 are rotatably engaged. In use, the rotating cylinder 5 is used to contact the lower wall of the color-coated sheet, and its function is to prevent friction damage to the color-coated sheet. Coaxial support shafts 6 are provided at both ends of the horizontal shaft 3. A U-shaped connecting frame 7 is provided between the horizontal shaft 3 and the sliding sleeve 4. The two ends of the opening of the U-shaped connecting frame 7 are rotatably connected to the opposite ends of the horizontal shaft 3 and the sliding sleeve 4, respectively. In specific implementation, the two ends of the opening of the U-shaped connecting frame 7 are fixedly connected to connecting sleeves respectively fitted onto the outside of the horizontal shaft 3 and the sliding sleeve 4. The connecting sleeves are rotatably connected to the corresponding horizontal shaft 3 and the sliding sleeve 4 through bearings. When the sliding sleeve 4 moves, it can drive the horizontal shaft 3 to move axially through the U-shaped connecting frame 7. A rotating cylinder 220 is fitted onto the support shaft 6, and the rotating cylinder 220 is rotatably connected to the support shaft 6. The function of the rotating cylinder 220 is the same as that of the rotating cylinder 5. In use, the first rotating cylinder 5 supports the middle section of the cut color-coated steel sheet, and the second rotating cylinder 220 supports the two side sections of the cut color-coated steel sheet. In this embodiment, the color-coated steel sheet is laser-cut into three sections (with the same or different widths). It should be noted that the U-shaped connecting frame 7 creates a gap between the horizontal axis 3 and the opposite sliding sleeve 4. This gap is used to allow space when bending adjacent sections of the cut color-coated steel sheet.

[0023] A support arm 8 is fixedly connected to the upper side of the U-shaped connecting frame 7 at the non-open end. The support arm 8 is perpendicular to the U-shaped connecting frame 7. A roller 9 is rotatably connected to one side of the support arm 8 and is located on the side of the adjacent support shaft 6 and parallel to the support shaft 6. The function of the roller 9 is also to support the cut color-coated plate. When the U-shaped connecting frame 7 swings up and down, the roller 9 can lift the two outermost plates on the left and right sides after the color-coated plate is cut. A lifting driver 108 is set at the bottom of the transmission frame 1, located below the roller 9. The top of the lifting driver 108 is movably connected to one side of the adjacent U-shaped connecting frame 7. The lifting driver 108 is one of a hydraulic cylinder, an electric push rod, or a pneumatic cylinder. The bottom of the lifting driver 108 is rotatably connected to the bottom wall of the trough frame 11. One U-shaped connecting frame 7 corresponds to one lifting driver 108. When the lifting driver 108 extends or retracts, it can control the corresponding U-shaped connecting frame 7 to rotate up and down, thereby lifting the cut plate through the roller 9.

[0024] In this embodiment, an upper and lower slide frame 101 is sleeved on the vertical shaft 2, and a left and right slide frame 102 is provided on the upper and lower slide frame 101. When the upper and lower slide frame 101 moves up and down, it can drive the left and right slide frames 102 to move up and down together. The top of the left and right slide frames 102 is hinged to the bottom of the slide sleeves 4 on both sides of the vertical shaft 2 through two connecting rods 103 respectively. When the left and right slide frames 102 move left and right, they can drive the corresponding two slide sleeves 4 to move synchronously and in the same direction through the two connecting rods 103. When the upper and lower slide frame 101 moves up and down, it can indirectly adjust the distance between the two slide sleeves 4 through the two connecting rods 103. The distance between the two slide sleeves 4 is determined according to the width of the plate body supported by the corresponding rotating drum 5. The position of the two slide sleeves 4 in the axial direction on the horizontal shaft 3 is also determined according to the width of each plate body after the color-coated plate is cut.

[0025] Specifically, the upper and lower slides 101 include a vertical sleeve 1011 and a horizontal sleeve 1012 fixedly disposed on one side of the vertical sleeve 1011. The vertical sleeve 1011 is sleeved on the vertical shaft 2 and the two slide in a sliding fit. The left and right slides 102 are rectangular frame structures and the crossbeam 1021 at the bottom of the slides is sleeved in the horizontal sleeve 1012. The crossbeam 1021 and the horizontal sleeve 1012 are slidably connected. A motor 105, a servo motor, is fixedly connected to the top wall of the base plate 21. The output shaft of the motor 105 is fixedly connected to a lead screw 1051, which provides driving force to the rotation of the lead screw 1051. A threaded sleeve 10111, fitted around the lead screw 1051, is fixedly connected to the outer wall of the vertical sleeve 1011 via a plate. The threaded sleeve 10111 and the lead screw 1051 are screwed together. When the lead screw 1051 rotates, it can drive the vertical sleeve 1011 to move up and down along the vertical shaft 2 via the threaded sleeve 10111. The left and right slides 102 are equipped with threaded... The second rod 106 has a motor 107 fixedly connected to one end inside the left and right slides 102. The second motor 107 is a servo motor. The output shaft of the second motor 107 is fixedly connected to one end of the lead screw 106. The second motor 107 provides driving force to the rotation of the lead screw 106. The top wall of the transverse sleeve 1012 is fixedly connected to the second plate 101, and the second sleeve 10121 is screwed to the lead screw 106. When the lead screw 106 rotates, it can drive the entire left and right slides 102 to move laterally relative to the transverse sleeve 1012 through the second sleeve 10121.

[0026] In this embodiment, two support rods 111 are fixedly connected to the bottom wall of the slot frame 11, respectively close to both sides. The top of the support rod 111 is fixedly connected to a limiting sleeve 1111 sleeved on the outside of the support shaft 6. The limiting sleeve 1111 and the support shaft 6 are axially slidingly engaged. A transmission shaft 71 is fixedly connected to one side of the U-shaped connecting frame 7 at the free end. A connecting sleeve 1081 is fixedly connected to the actuating end of the lifting drive 108. A rotating sleeve 10811 is sleeved inside the connecting sleeve 1081. The rotating sleeve 10811 is sleeved on the outside of the transmission shaft 71 and the two are axially slidingly engaged. The function of the support rod 111 is to support the support shaft 6 and ensure that the support shaft 6 is in a horizontal state.

[0027] In this technical solution, the transmission frame 1 is provided with three winding rollers 104 near one end. One winding roller 104 is located in the middle of the upper part of the transmission frame 1. This winding roller 104 is used to wind the middle plate after the color-coated plate is cut. The other two winding rollers 104 are located behind the two ends of the above-mentioned winding roller 104. The other two winding rollers 104 are staggered and are used to wind the other two plates formed after cutting. The staggered arrangement of the three winding rollers 104 facilitates the individual winding of the three plates.

[0028] Specifically, a gantry 109 is fixedly connected above the transmission frame 1, located on the upper side behind the horizontal axis 3. The two ends of the bottom of the gantry 109 are fixedly connected to the top walls of the two parallel beams on the transmission frame 1, respectively. A connecting seat 1091 is fixedly connected to the top of the gantry 109. A cantilever 110 is fixedly connected to the front side of the connecting seat 1091. Arm plates 1101 located at the adjacent ends of the other two winding rollers 104 are fixedly connected to both sides of the cantilever 110. A rotating shaft 120 is provided on the arm plate 1101. A mating sleeve 1201 is fixedly connected to one end of the rotating shaft 120. The mating sleeve 1201 is inserted into one end of the roller shaft of the winding roller 104. The insertion here is a spline insertion. When the rotating shaft 120 rotates, it can drive the roller shaft to rotate. A drive motor is fixedly installed on the outer side of the cantilever 110. The output shaft of the drive motor is fixedly connected to one end of the rotating shaft 120. The drive motor is a servo motor. A left support plate 130 and a right support plate 140 are fixedly connected to the top and near the sides of the transmission frame 1. The bottom ends of the left support plate 130 and the right support plate 140 are fixedly connected to the top walls of the two parallel beams, respectively. The top of the left support plate 130 and the right support plate 140 are each provided with an axially sliding rotating shaft 150. Specifically, a positioning sleeve is welded to the top of the left support plate 130 and the right support plate 140. A guide sleeve is fitted inside the positioning sleeve. The guide sleeve and the positioning sleeve are rotatably connected. The guide sleeve is fitted outside the rotating shaft 150 and the two are axially slidingly engaged. One end of the rotating shaft 150 is fixedly connected to a mating sleeve 1501 that is inserted into and engaged with the other end of the roller shaft of the winding roller 104. The outer walls of the left support plate 130 and the right support plate 140 are fixedly connected to an electric push rod through a machine base. The output shaft of the electric push rod is rotatably connected to one end of the rotating shaft 150. The electric push rod provides driving force for the axial movement of the rotating shaft 150. It should be noted that two vertical beams are fixedly connected to the front end of the top wall of the transmission frame 1. The transmission and assembly / disassembly operation of the two vertical beams and the foremost winding roller 104 are the same as the assembly / disassembly operation of the other winding rollers 104. The insertion method of the aforementioned docking sleeve 1201 and docking sleeve 2 1501 with the roller shaft makes the assembly / disassembly of the winding roller 104 more convenient.

[0029] In this embodiment, a liftable portal frame 160 is provided inside the gantry frame 109. Specifically, a control cylinder is fixedly connected to the top of the gantry frame 109, and the output shaft of the control cylinder is fixedly connected to the top wall of the portal frame 160. When the control cylinder is activated, it can control the portal frame 160 to move up and down. A pressure roller 170 is rotatably connected to the bottom of the portal frame 160. A row of transmission rollers 180 is provided inside the transmission frame 1, and one of the transmission rollers 180 is located directly below the pressure roller 170. During use, the color-coated plate will pass between the pressure roller 170 and the transmission roller 180 above it. After the pressure roller 170 moves down to a certain position, it can lightly press the color-coated plate onto the transmission roller 180 below, so as to prevent the color-coated plate from deforming.

[0030] In this embodiment, a positioning frame 190 located behind the pressure roller 170 is fixedly connected to the top of the transmission frame 1. The positioning frame 190 is also a gate-shaped structure. Two transverse slides 210 distributed front and back are provided inside the positioning frame 190. Specifically, two guide rails are fixedly connected between the two side walls inside the positioning frame 190. The two transverse slides 210 are slidably connected to the two guide rails respectively. The bottom of the transverse slides 210 is connected to a laser cutter 200 through a hanger. When the transverse slides 210 slides, it can drive the laser cutter 200 to move laterally, thereby changing the position for cutting the color-coated plate. When the two laser cutters 200 move laterally with a large stroke, they can cut the color-coated plate. The positioning frame 190 is equipped with two lead screws, the two ends of which are rotatably connected to opposite sides of the positioning frame 190. Drive motors are fixedly installed on both sides of the positioning frame 190. One end of each lead screw is fixedly connected to the output shaft of the two drive motors. The drive motors are servo motors. The two drive motors provide driving force to the rotation of the corresponding lead screws. The top walls of the two transverse slides 210 are fixedly connected with threaded sleeves that are screwed into the two lead screws. Thus, when the lead screws rotate, they can drive the corresponding transverse slides 210 to move laterally.

[0031] In this embodiment, the outer peripheral wall of the winding roller 104 is fixedly connected with circumferentially evenly distributed screw holes 1041. The screw holes 1041 on the winding roller 104 are also arranged along the axial direction of the winding roller 104. These screw holes 1041 are used to fix the three plates formed by the cut color-coated plate. When the three plates are respectively attached to the three winding rollers 104, a tool is used to screw the self-tapping screw into the screw hole 1041. When screwing in, the self-tapping screw passes through the plate, so that the plate is tightly attached to the corresponding winding roller 104.

[0032] Working principle: In use, the processed and uncoiled color-coated sheet is placed on the transmission roller 180 on the transmission frame 1. Then, the two transverse slides 210 are controlled to move left and right to adjust the position of the laser cutter 200, controlling the color-coated sheet to move forward. Then, the two laser cutters 200 are started, and the two laser cutters 200 cut the color-coated sheet. The cut color-coated sheet will form three strips of the same or different widths (depending on requirements). Then, according to the width of the three strips, motor 105 is started, the lead screw 1051 rotates, the vertical sleeve 1011 moves, and then through the two connecting rods 103, it drives the two sliding sleeves 4 to move axially, so that the distance between the opposite ends of the two sliding sleeves 4 changes. This distance is approximately the same as the middle strip after the color-coated sheet is cut. Then, motor 2 107 is started, the lead screw 2 106 is driven to rotate, and under the restriction of the lead sleeve 2 10121, the left and right slides 102 move laterally. Driven by the connecting rod 103, the two sliding sleeves 4 and the two horizontal shafts 3 will shift as a whole, so that the two cutting seams in the three plates are respectively aligned with the inner grooves of the two U-shaped connecting frames 7. Then, the two lifting drivers 108 are controlled to move. The two lifting drivers 108 have different strokes. At this time, the two U-shaped connecting frames 7 will swing up with different swing amplitudes. As a result, the rollers 9 corresponding to the two U-shaped connecting frames 7 will push the two plates passing above to tilt upward. The two plates will adhere to the outer peripheral walls of the two rear winding rollers 104. Then, the plates are fixed to the corresponding winding rollers 104 through the screw holes 1041 using self-tapping screws. Then, the middle plate is fixed to the outer wall of the frontmost winding roller 104 using self-tapping screws. Then, the color-coated plates on the transfer frame 1 continue to be transferred. By controlling the three winding rollers 104 to rotate synchronously, the winding process of the three plates can be achieved.
