Description

Technical Field

[0001] The present invention relates to the technical field of coil leveling devices, in particular to a coil leveling device for a laser cutting machine. Background Art

[0002] After the production of some metal sheets, such as stainless steel and aluminum sheets, they need to be coiled for storage and transportation. These coils are coiled together for a long time. Due to the large number of curling layers, the curling stress on the sheets is relatively high. After uncoiling, the sheets are still in a certain state of bending, which makes it difficult to accurately measure their straight length during the laser cutting process. After cutting, the actual cut size is too long, which not only causes waste but also requires recalibration before cutting again, greatly reducing processing efficiency.

[0003] These coils need to be leveled by a leveling device before being cut. Most existing leveling devices level the coils through rollers or pressure plates, but there are still certain defects in actual operation. Due to the metal stress inside the steel strip, the edge of the plate will be warped under the action of the metal stress after leveling, resulting in deformation of the plate, affecting subsequent measurement, cutting and other operations, which is not conducive to actual use.

The cam 33 is a kind of cam 33 that is fixed on the cam 33 of the lower part of the cam 33. A hot air blower 38 is fixedly installed on the upper end of the concave support seat 12, and air outlet ends are provided on the left and right sides of the hot air blower 38. A hose 39 is fixedly installed on the two air outlet ends on the left and right sides of the hot air blower 38. A through groove is symmetrically opened on the upper end of the concave support seat 12. The lower end of the hose 39 extends downward through the through groove to the inner cavity of the concave support seat 12. The lower end of the hose 39 is connected to the upper end of the inlet pipe 35 through a pipe joint.

[0025] A connecting pipe 36 is fixedly connected to the rear end of the ventilation box 34 on the inner side of the raised part at the lower end of the concave limit seat 3. The inlet pipe 35 and the connecting pipe 36 are both connected to the inner cavity of the ventilation box 34. The rear side of the concave limit seat 3 is fixedly connected to the hot air knife 37 through an L-shaped frame. The rear end of the connecting pipe 36 is fixedly connected to the side of the hot air knife 37, and the connecting pipe 36 is connected to the inner cavity of the hot air knife 37.

[0026] The heating assembly includes a heating roller 4 rotatably mounted in the groove 31. Circular slots are symmetrically provided at the left and right ends of the heating roller 4. A spiral groove 41 is provided on the inner side of the heating roller 4. The two ends of the spiral groove 41 are respectively connected to the two circular slots at the two ends of the heating roller 4. A vent pipe 42 is fixedly inserted into the two circular slots at the two ends of the heating roller 4. The vent pipe 42 is connected to the spiral groove 41 through the circular slot. The vent pipe 42 is inserted into the circular hole 32. A sealing ring 43 is fixedly sleeved on the end of the vent pipe 42 away from the heating roller 4.

[0027] The heating roller 4 is in rolling contact with the upper end of the plate body 13, the vent pipe 42 is rotatably connected to the circular hole 32, the sealing ring 43 is clamped with the annular groove 33, and the sealing ring 43 is rotatably connected to the annular groove 33, and the two ends of the vent pipe 42 are respectively connected to the vent box 34 and the spiral groove 41.

[0028] The hot air blower 38 delivers hot air to the inlet pipe 35 through the hose 39. The hot air flows along the inlet pipe 35 into the ventilation box 34. The hot air flows along the inner cavity of the ventilation box 34 into the ventilation pipe 42, and then flows along the ventilation pipe 42 and the circular slot into the spiral groove 41. The hot air heats the heating roller 4 in the process of flowing along the spiral groove 41. The spiral groove 41 allows the hot air to stay in the heating roller 4 for as long as possible, thereby effectively heating the heating roller 4. Hot air flows in from one end of the spiral groove 41 and flows out from the other end. At this time, the hot air after heating the heating roller 4 flows into the hot air knife 37 through the circular slot, the ventilation pipe 42, the ventilation box 34, and the connecting pipe 36. Finally, the hot air is blown downward along the air outlet at the lower end of the hot air knife 37, thereby heating the plate body 13.

[0029] As the sheet body 13 moves from back to front along the upper end of the lower roller shaft 11, the hot air blown downward from the air outlet at the lower end of the hot air knife 37 first heats the sheet body 13. At the same time, the edges on both sides of the sheet body 13 pass through the lower end of the heating roller 4. At this time, the heating roller 4 rolls along the upper end of the edge of the sheet body 13, and the edge of the sheet body 13 is further heated by the heating roller 4.

[0030] The heated plate body 13 is leveled by the leveling roller 24, and at the same time the edge pressing tube 26 levels the edge of the plate body 13 again to prevent warping at the edge of the plate body 13 as much as possible. The plate body 13 is heated by the set heating mechanism, which greatly improves the effect of subsequent leveling of the plate body 13.

[0031] See also Figure 2 、 Figure 3 、 Figures 8 to 12The detection mechanism includes an L-shaped plate 5 fixedly mounted on the front end of the lifting adjustment plate 21. The lower end of the L-shaped plate 5 is recessed upward to form a movable groove 51. The front and rear inner walls of the movable groove 51 are symmetrically provided with lifting grooves 52. The lifting grooves 52 on the front and rear inner walls of the movable groove 51 are symmetrically distributed front to back. A transmission gear 53 is connected to the movable groove 51 through a rotating shaft. The left and right sides of the transmission gear 53 are symmetrically meshed with a first tooth plate 6 and a second tooth plate 7. The lower ends of the first tooth plate 6 and the second tooth plate 7 extend downward to the movable groove. On the outside of 51, the lower end of the first tooth plate 6 is fixedly connected to a roller bracket 61, and a detection roller 62 is rotatably connected to the roller bracket 61 through a rotating shaft. The detection roller 62 is in rolling contact with the upper end of the plate body 13, and a reset spring 63 is fixedly installed on the upper end of the first tooth plate 6. The upper end of the reset spring 63 abuts against the upper end of the inner cavity of the movable groove 51. The lower end of the second tooth plate 7 is recessed upward to form a circular groove 71, and the inner front end of the circular groove 71 is symmetrically penetrated by a sliding groove 72, and a marking mechanism is installed at the lower end of the circular groove 71.

[0032] The first tooth plate 6 and the second tooth plate 7 are both in sliding contact with the movable groove 51 , and the front and rear sides of the first tooth plate 6 and the second tooth plate 7 are symmetrically fixedly connected with lifting blocks 73 , which are slidably connected with the lifting groove 52 .

[0033] The moving directions of the first tooth plate 6 and the second tooth plate 7 are opposite. When the first tooth plate 6 and the second tooth plate 7 move up and down, the first tooth plate 6 and the second tooth plate 7 both drive the lifting block 73 to slide up and down along the lifting slot 52, so that the first tooth plate 6 and the second tooth plate 7 can move up and down stably.

[0034] The marking mechanism includes a telescopic cylinder 8 that is slidably installed in a circular groove 71 up and down. The lower end of the telescopic cylinder 8 extends downward through the circular groove 71 to the outside. A mounting groove 81 is provided at the lower end of the telescopic cylinder 8. The upper end of the telescopic cylinder 8 is symmetrically fixed with a slider 82 front and back. A buffer spring 83 is inserted into the upper end of the telescopic cylinder 8. A marking pen 84 is inserted into the mounting groove 81. The marking head of the marking pen 84 extends downward to the outside of the mounting groove 81. A locking bolt 85 is threadedly installed on the lower end of the side surface of the telescopic cylinder 8. The end of the locking bolt 85 extends into the mounting groove 81, and the end of the locking bolt 85 abuts against the side surface of the marking pen 84.

[0035] The slider 82 is connected to the slide groove 72 for upward and downward sliding. The two ends of the buffer spring 83 are respectively plugged into the upper end of the telescopic cylinder 8 and the upper end of the inner cavity of the circular groove 71. The buffer spring 83 applies a downward elastic force to the telescopic cylinder 8. The marking head of the marking pen 84 is set above the plate body 13. There is a gap between the marking pen 84 and the plate body 13. When the edge of the plate body 13 is not curled up, the marking pen 84 will not contact the upper end of the plate body 13.

[0036] The distance between the L-shaped plate 5 and the lifting adjustment plate 21 can be adjusted as needed. If the distance between the L-shaped plate 5 and the lifting adjustment plate 21 is required to be farther, a bracket such as an extension plate can be added to connect them. As long as the L-shaped plate 5 and the lifting adjustment plate 21 are relatively fixed, the lifting adjustment plate 21 can drive the L-shaped plate 5 to move up and down synchronously when it moves up and down. The L-shaped plate 5 and the lifting adjustment plate 21 are detachably connected, and the distance between the two L-shaped plates 5 can be adjusted as needed, thereby changing the detection position of the detection mechanism.

[0037] When the sheet body 13 moves, the detection roller 62 rolls along the upper end of the sheet body 13. If the edge of the sheet body 13 does not warp, the detection roller 62 rolls steadily along the upper end of the sheet body 13, and the marking pen 84 does not move to mark. If the edge of the plate body 13 is warped, when the warped edge of the plate body 13 moves to the bottom of the detection roller 62, the warped edge of the plate body 13 will push the detection roller 62 to move upward, and the detection roller 62 drives the first tooth plate 6 to slide upward along the movable groove 51 through the roller bracket 61. The first tooth plate 6 squeezes the reset spring piece 63, and at the same time, the first tooth plate 6 drives the transmission gear 53 to rotate, and the transmission gear 53 drives the second tooth plate 7 to move downward, and the second tooth plate 7 drives the marking mechanism to move downward, so that the marking head of the marking pen 84 in the marking mechanism contacts the upper end of the plate body 13, thereby marking the plate body 13, so that the staff can clearly see the position of the warped edge of the plate body 13.

[0038] When the second tooth plate 7 moves downward, it drives the buffer spring 83 downward, and the buffer spring 83 drives the marking pen 84 downward through the telescopic cylinder 8, so that the marking head of the marking pen 84 contacts the upper end of the sheet body 13 to mark. At this time, if the edge of the sheet body 13 is tilted higher, the second tooth plate 7 will continue to move downward. Since the lower end of the marking pen 84 contacts the upper end of the sheet body 13, the marking mechanism will not move further downward. At this time, when the second tooth plate 7 continues to move downward, the circular groove 71 of the second tooth plate 7 slides downward along the telescopic cylinder 8, causing the telescopic cylinder 8 to shrink into the circular groove 71. At the same time, the slide groove 72 slides downward along the slider 82, and the circular groove 71 cooperates with the telescopic cylinder 8 to squeeze the buffer spring 83.

[0039] When the raised edge of the plate body 13 is removed, and the edge of the plate body 13 below the detection mechanism is not raised, the first tooth plate 6 moves downward under the action of the elastic force of the reset spring piece 63, and the first tooth plate 6 drives the second tooth plate 7 to move upward through the transmission gear 53. The circular groove 71 of the second tooth plate 7 first slides upward along the telescopic cylinder 8. At this time, the second tooth plate 7 continues to move upward. When the slider 82 slides to the bottom of the slide groove 72, the second tooth plate 7 continues to move upward and will drive the slider 82 to move upward. The slider 82 drives the marking pen 84 to move upward through the telescopic cylinder 8, thereby separating the marking head of the marking pen 84 from the upper end of the plate body 13.

[0040] When the marking pen 84 needs to be replaced, first unscrew the locking bolt 85 outward along the telescopic cylinder 8 to separate the end of the locking bolt 85 from the marking pen 84. At this time, the marking pen 84 can be easily removed from the mounting groove 81, and then a new marking pen 84 is inserted into the mounting groove 81, and the locking bolt 85 is screwed inward along the telescopic cylinder 8 until the end of the locking bolt 85 abuts against the side of the marking pen 84, thereby completing the locking of the marking pen 84.

[0041] Working principle: During operation, the sheet body 13 moves from back to front along the upper end of the lower roller 11, and the sheet body 13 passes through the bottom of the hot air knife 37, the heating roller 4, the smoothing roller 24, and the edge pressing tube 26 in sequence; The hot air blower 38 is sent into the ventilation box 34 through the hose 39 and the inlet pipe 35. The hot air flows along the ventilation pipe 42 and the circular slot into the spiral groove 41. The hot air heats the heating roller 4 while flowing along the spiral groove 41, and the heating roller 4 heats the edge of the plate body 13. Hot air flows in from one end of the spiral groove 41 and flows out from the other end. At this time, the hot air after heating the heating roller 4 flows into the hot air knife 37 through the circular slot, the ventilation pipe 42, the ventilation box 34, and the connecting pipe 36. Finally, the hot air is blown downward along the air outlet at the lower end of the hot air knife 37, thereby heating the plate body 13.

[0042] The hot air knife 37 and the heating roller 4 cooperate to heat the plate body 13 , especially the edges of the plate body 13 .

[0043] The heated plate body 13 is leveled by the leveling roller 24, and at the same time the edge pressing tube 26 levels the edge of the plate body 13 again to prevent warping at the edge of the plate body 13 as much as possible. The plate body 13 is heated by the set heating mechanism, which greatly improves the effect of subsequent leveling of the plate body 13.

[0044] The flattened plate body 13 passes through the bottom of the detection mechanism, and the detection roller 62 rolls along the upper end of the plate body 13; At this time, if the edge of the plate body 13 does not show any warping phenomenon, the detection roller 62 rolls steadily along the upper end of the plate body 13, and the marking pen 84 does not believe that it moves to mark; If the edge of the plate body 13 is warped, when the warped edge of the plate body 13 moves to the bottom of the detection roller 62, the warped edge of the plate body 13 will push the detection roller 62 to move upward, and the detection roller 62 drives the first tooth plate 6 to move upward through the roller bracket 61, and the first tooth plate 6 drives the second tooth plate 7 to move downward through the transmission gear 53, and the second tooth plate 7 drives the marking mechanism to move downward, so that the marking head of the marking pen 84 in the marking mechanism contacts the upper end of the plate body 13, thereby marking the plate body 13, so that the staff can clearly see the position of the warped edge of the plate body 13, which is convenient for subsequent repair or re-leveling.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
