Description

Technical Field

[0001] The present invention relates to the technical field of aromatic fabric cutting, and particularly relates to an automatic laser cutting device for aromatic fabrics. Background Art

[0002] An aromatic fabric is a fabric with an aromatic smell. During the production of aromatic fabrics, a laser beam emitted from a laser head is used to precisely cut the aromatic fabric, and multiple small-area fabrics of required shapes can be cut from a whole piece of aromatic fabric, improving the cutting efficiency.

[0003] Currently, the height of the laser head during the cutting of aromatic fabrics is fixed. Since the laser beam emitted from the laser head irradiates the high-power density laser beam onto the fabric surface, causing the fabric to vaporize after reaching the melting point or boiling point, for fabrics of different thicknesses, it is necessary to adjust the distance between the laser beam and the fabric surface to ensure the quality of fabric laser cutting. Too high or too low will cause incomplete cutting of the fabric or the phenomenon that the cutting edge is overheated and charred. And after the fabric is cut, some carbonized substances adhering to its surface will remain on the cutting board below it. If not processed in time, it is easy to cause the fabric to wrinkle together during the subsequent fabric conveying process. Summary of the Invention

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Refer to Figure 1 - Fig. 9 , an automatic laser cutting device for aromatic fabric, including a cutting box 1. The cutting box 1 is in an L shape. An opening 2 is provided on the inner wall of the cutting box 1. A conveyor plate 3 is fixedly connected to the inner bottom of the opening 2. An aromatic fabric body 4 is arranged above the conveyor plate 3.

[0021] Cutting mechanism, the cutting mechanism includes two first rectangular rods 5 fixedly connected to the inner wall of the cutting box 1. A first plate 6 is slidably connected to the side walls of the two first rectangular rods 5. A first U-shaped plate 7 is slidably connected through the side wall of the first plate 6. A laser cutting head 8 is fixedly connected to the lower end of the first U-shaped plate 7. The side wall of the first U-shaped plate 7 is elastically connected to the lower end of the first plate 6 through a plurality of first springs 9. A groove 38 is opened at the top of the cutting box 1. A convex plate 39 is elastically connected to the inner wall of the groove 38 through a plurality of second springs 40. A pressing roller 41 is rotatably connected to the side wall of the first U-shaped plate 7 above the first plate 6 through a rotating shaft. The pressing roller 41 is in contact with the side wall of the convex plate 39 during movement (as Figure 3 and Figure 4 shown).

[0022] A moving mechanism is provided on the cutting box 1. The moving mechanism includes a first one-way bearing 16. A first reciprocating lead screw 14 is rotatably connected to the inner wall of the cutting box 1. The side wall of the first reciprocating lead screw 14 is threadedly connected to the side wall of the first plate 6. A first motor 15 is fixedly connected to the side wall of the cutting box 1 through a bracket. The side wall of the movable shaft of the first motor 15 is fixedly connected to the outer side wall of the first one-way bearing 16 through a fixing ring (as Figure 5 shown), and the side wall of the first reciprocating lead screw 14 is fixedly connected to the inner side wall of the first one-way bearing 16.

[0023] As Figure 3 -as Figure 5 shown, when the first motor 15 rotates counterclockwise, at this time the fixing ring drives the outer side wall of the first one-way bearing 16 to rotate counterclockwise. The outer side wall of the first one-way bearing 16 drives its inner ring to rotate, drives the first reciprocating lead screw 14 to rotate counterclockwise, drives the first plate 6 to move. During the movement of the first plate 6, at this time, under the extrusion of the convex plate 39, the pressing roller 41 will drive the first U-shaped plate 7 and the laser cutting head 8 to move downward, and adjust the distance between the laser cutting head 8 and the aromatic fabric body 4. When the first motor 15 rotates clockwise, at this time the outer ring of the first one-way bearing 16 does not drive its inner ring to rotate.

[0024] A conveying mechanism is provided on the cutting box 1. The conveying mechanism includes a first conveying roller 28 and a second conveying roller 30. Two electric push rods 33 are fixedly connected to the upper end of the cutting box 1. A first L-shaped plate 32 is fixedly connected to the upper ends of the two electric push rods 33. A second U-shaped plate 27 is fixedly connected to the lower end of the first L-shaped plate 32. The side wall of the second U-shaped plate 27 is rotatably connected to the side wall of the first conveying roller 28 through a rotating shaft. The side wall of the cutting box 1 below the conveying plate 3 is fixedly connected with a third U-shaped plate 29 through a bracket. The side wall of the third U-shaped plate 29 is rotatably connected to the side wall of the second conveying roller 30 through a rotating shaft. Second motors 31 for driving the rotating shaft to rotate are provided on both the second U-shaped plate 27 and the third U-shaped plate 29. By setting the electric push rods 33, the height of the first conveying roller 28 can be adjusted, so that the first conveying roller 28 and the second conveying roller 30 can convey aromatic fabric bodies 4 with different thicknesses.

[0025] An adjusting mechanism is provided on the cutting box 1. The adjusting mechanism includes a second L-shaped plate 34 fixedly connected to the upper end of the cutting box 1. A chute 35 is opened at the lower end of the second L-shaped plate 34. A wedge-shaped plate 36 is slidably connected to the inner wall of the chute 35. The side wall of the wedge-shaped plate 36 is slidably connected to the inner wall of the chute 35 through a plurality of third springs 37. A sliding plate 42 is fixedly connected to the upper end of the convex plate 39. A first wedge-shaped block 43 (as Figure 2 shown) that cooperates with the lower end of the wedge-shaped plate 36 is fixedly connected to the upper end of the first L-shaped plate 32. A second wedge-shaped block 44 (as Figure 2 shown) that cooperates with the lower end of the wedge-shaped plate 36 is fixedly connected to the upper end of the sliding plate 42.

[0026] As Figure 2 and Figure 3 shown, when conveying a relatively thick aromatic fabric body 4, at this time the two electric push rods 33 extend, and the first L-shaped plate 32 drives the first conveying roller 28 to move upward through the second U-shaped plate 27. When the first L-shaped plate 32 moves upward, at this time the first wedge-shaped block 43 will squeeze the wedge-shaped plate 36 to slide to the right. At this time, the wedge-shaped plate 36 will squeeze the second wedge-shaped block 44 to move downward. Then the second wedge-shaped block 44 drives the convex plate 39 to move downward through the sliding plate 42, reducing the distance between the lower end of the convex plate 39 and the upper end of the aromatic fabric body 4. Then when the first plate 6 moves subsequently, at this time under the squeezing action of the convex plate 39, the pressing roller 41 will drive the first U-shaped plate 7 and the laser cutting head 8 to move downward, so that the distance between the laser cutting head 8 and the aromatic fabric body 4 is shorter; When the thinner aroma cloth body 4 is conveyed, the two electric push rods 33 are retracted, and the first L-shaped plate 32 drives the first conveying roller 28 to move downward through the second L-shaped plate 27. When the first L-shaped plate 32 moves downward, the first wedge block 43 does not squeeze the wedge plate 36. At this time, under the elastic force of the plurality of third springs 37, the wedge plate 36 moves to the left. At this time, under the elastic force of the plurality of second springs 40, the second wedge block 44 drives the raised plate 39 to move upward through the slide plate 42, increasing the lower end of the raised plate 39 and the aroma cloth body 4. The distance between the upper ends, then when the first plate 6 moves subsequently, the squeezing roller 41, under the squeezing effect of the raised plate 39, will drive the first shaped plate 7 and the laser cutting head 8 to move downward, so that the distance between the laser cutting head 8 and the fragrance cloth body 4 is longer. In this way, the height of the laser cutting head 8 can be automatically adjusted according to the thickness of the fragrance cloth body 4, avoiding the problem that the height of the laser head in the prior art is fixed, resulting in incomplete cutting of the fragrance cloth or overheating and burning of the cutting edge when cutting fragrance cloths of different thicknesses.

[0027] The conversion mechanism includes a through slot 10 provided on the conveying plate 3 near the laser cutting head 8. The inner wall of the through slot 10 is rotatably connected to two bearing plates 12 through two first rods 11. A material receiving box 13 is fixedly connected to the bottom of the cutting box 1. Figure 1 As shown, the material receiving box 13 is located below the right side carrying plate 12 , and the material receiving box 13 can collect the cut fragrance cloth body 4 .

[0028] like Figure 3 As shown, the aromatic cloth body 4 is located on two supporting plates 12. When the laser cutting head 8 cuts the aromatic cloth body 4 and the laser cutting head 8 moves up to the initial position, the two supporting plates 12 rotate half a circle clockwise, which not only allows the cut aromatic cloth body 4 to flow out automatically, but also allows the cutting surfaces of the two supporting plates 12 to be replaced, which is convenient for the subsequent cleaning of the cutting surfaces of the supporting plates 12.

[0029] The first motor 15 is provided with a rotating mechanism, which includes a second one-way bearing 17. The inner ring of the second one-way bearing 17 is fixedly connected to the side wall of the movable shaft of the first motor 15, and the side wall of the outer ring of the second one-way bearing 17 is fixedly connected to the first wheel 18. The ends on the same side of the two first rods 11 penetrate the side wall of the cutting box 1 and are fixedly connected to the second wheel 19. A synchronous belt is connected between the first wheel 18 and the two second wheels 19.

[0030] like Figure 3 - Figure 5As shown in the figure, when the first motor 15 rotates clockwise, the inner ring of the second one-way bearing 17 drives its outer ring to rotate at this time. Then, through the first wheel 18, the synchronous belt and the two second wheels 19, the two first rods 11 are driven to rotate clockwise, driving the two bearing plates 12 to rotate clockwise by half a turn. When the first motor 15 rotates counterclockwise, the inner ring of the second one-way bearing 17 does not drive its outer ring to rotate at this time.

[0031] A cleaning mechanism is provided in the cutting box 1. The cleaning mechanism includes a second rectangular rod 20 fixedly connected to the inner wall of the cutting box 1 below the conveying plate 3. A second plate 21 is slidably connected to the side wall of the second rectangular rod 20. A collecting groove 22 is opened at the upper end of the second plate 21. A scraping plate 23 is fixedly connected to the bottom of the collecting groove 22 through a bracket. The upper surface of the scraping plate 23 is at the same height as the lower surfaces of the two bearing plates 12.

[0032] A second reciprocating lead screw 24 is rotatably connected to the side wall of the cutting box 1. The side wall of the second reciprocating lead screw 24 is threadedly connected to the side wall of the second plate 21. A third wheel 25 is fixedly connected to the side wall of the first reciprocating lead screw 14. A fourth wheel 26 is fixedly connected to the side wall of the second reciprocating lead screw 24. A synchronous belt is connected between the third wheel 25 and the fourth wheel 26.

[0033] As Figure 3 - Figure 6 As shown in the figure, when the first reciprocating lead screw 14 rotates counterclockwise, at this time, the second reciprocating lead screw 24 is driven to rotate through the third wheel 25, the synchronous belt and the fourth wheel 26, driving the second plate 21 and the scraping plate 23 to move. At this time, the scraping plate 23 can scrape off some carbonized substances adhering to the lower surfaces of the two bearing plates 12 due to laser cutting, avoiding the presence of carbonized substances that easily cause wrinkles in the subsequent fabric conveying process.

[0034] A deviation rectifying mechanism is provided on the cutting box 1. The deviation rectifying mechanism includes a slider 45 slidably connected to the top of the cutting box 1. The upper end of the slider 45 is fixedly connected to the lower end of the first L-shaped plate 32. The lower end of the slider 45 is fixedly connected to a cross plate 46. Two fourth U-shaped plates 47 are fixedly connected to the lower end of the cross plate 46. A deviation rectifying roller 50 is rotatably connected to the side wall of one of the fourth U-shaped plates 47 through a second rod 48. A deviation rectifying roller 50 is rotatably connected to the side wall of the other fourth U-shaped plate 47 through a third rod 49. A third L-shaped plate 51 is fixedly connected to the side wall of the second U-shaped plate 27. A fourth rod 52 and a fifth rod 53 are rotatably connected to the side wall of the third L-shaped plate 51. A universal joint 54 is connected between the second rod 48 and the fourth rod 52. A universal joint 54 is connected between the third rod 49 and the fifth rod 53.

[0035] As Figure 7As shown, the two correcting rollers 50 are symmetrically inclined. The correcting roller 50 connected to the second rod 48 rotates counterclockwise, and the correcting roller 50 connected to the third rod 49 rotates clockwise, which can continuously pull and move the fragrance cloth body 4 to both sides during the conveying process, not only can the fragrance cloth body 4 be kept centered during conveying to avoid deviation of the fragrance cloth body 4 during conveying, but also the fragrance cloth body 4 can be leveled to improve the cutting quality of the fragrance cloth body 4.

[0036] The third L-shaped plate 51 is rotatably connected to the side wall close to the fourth rod 52, and the side wall of the sixth rod 55 is fixedly connected to the first gear 58, and the side wall of the fourth rod 52 is fixedly connected to the second gear 59, and the first gear 58 and the second gear 59 are meshed. The side walls of the fifth rod 53 and the sixth rod 55 are both fixedly connected to the sixth wheel 60, and a synchronous belt is connected between the two sixth wheels 60. One end of the rotating shaft on the second L-shaped plate 27 is fixedly connected to the first bevel gear 56, and the side wall of the sixth rod 55 away from the third L-shaped plate 51 is fixedly connected to the second bevel gear 57, and the first bevel gear 56 and the second bevel gear 57 are meshed.

[0037] like Figure 7 and Figure 8 As shown, when the first conveying roller 28 rotates counterclockwise, the sixth rod 55 is driven to rotate clockwise through the first bevel gear 56 and the second bevel gear 57. At this time, the sixth rod 55 drives the fourth rod 52 to rotate counterclockwise through the first gear 58 and the second gear 59, and then the fourth rod 52 drives the second rod 48 to rotate counterclockwise through the universal joint 54. At this time, the sixth rod 55 drives the fifth rod 53 to rotate clockwise through the two sixth wheels 60 and the synchronous belt, and then the fifth rod 53 drives the third rod 49 to rotate clockwise through the universal joint 54.

[0038] When the aroma cloth body 4 is laser cut, the aroma cloth body 4 is first passed between the first conveying roller 28 and the second conveying roller 30, and then the aroma cloth body 4 is placed on the conveying plate 3 through the opening 2, and then the two electric push rods 33 are adjusted so that the first L-shaped plate 32 adjusts the height of the first conveying roller 28 through the second L-shaped plate 27, so that the first conveying roller 28 and the second conveying roller 30 clamp the aroma cloth body 4, and then the two second motors 31 are started so that the first conveying roller 28 rotates counterclockwise and the second conveying roller 30 rotates clockwise to convey the aroma cloth body 4; When the first conveying roller 28 rotates counterclockwise, the first bevel gear 56 connected to the rotating shaft of the first conveying roller 28 drives the sixth rod 55 to rotate clockwise through the second bevel gear 57. At this time, the sixth rod 55 drives the fourth rod 52 to rotate counterclockwise through the first gear 58 and the second gear 59. Further, the fourth rod 52 drives the second rod 48 to rotate counterclockwise through the universal joint 54. And at this time, the sixth rod 55 drives the fifth rod 53 to rotate clockwise through the two sixth wheels 60 and the synchronous belt. Further, the fifth rod 53 drives the third rod 49 to rotate clockwise through the universal joint 54; At this time, the deviation rectifying roller 50 connected to the second rod 48 rotates counterclockwise, and the deviation rectifying roller 50 connected to the third rod 49 rotates clockwise, which can continuously pull and move the aromatic fabric body 4 to both sides during the conveying process. It can not only keep the aromatic fabric body 4 centered during conveying, avoid the deviation of the aromatic fabric body 4 during the conveying process, but also flatten the aromatic fabric body 4 to improve the cutting quality of the aromatic fabric body 4; Subsequently, the aromatic fabric body 4 is moved onto the two bearing plates 12 until it reaches the appropriate cutting length; The height adjustment of the first conveying roller 28 is carried out according to the thickness of the aromatic fabric body 4. When conveying the thicker aromatic fabric body 4, at this time, the two electric push rods 33 extend, and the first L-shaped plate 32 drives the first conveying roller 28 to move upward through the second U-shaped plate 27. When the first L-shaped plate 32 moves upward, at this time, the first wedge block 43 will squeeze the wedge plate 36 to slide to the right. At this time, the wedge plate 36 will squeeze the second wedge block 44 to move downward. Further, the second wedge block 44 drives the convex plate 39 to move downward through the slide plate 42, reducing the distance between the lower end of the convex plate 39 and the upper end of the aromatic fabric body 4. Then when the subsequent first plate 6 moves, at this time, under the extrusion of the convex plate 39, the extrusion roller 41 will drive the first U-shaped plate 7 and the laser cutting head 8 to move downward, so that the distance between the laser cutting head 8 and the aromatic fabric body 4 is shorter; When the thinner aroma cloth body 4 is conveyed, the two electric push rods 33 are retracted, and the first L-shaped plate 32 drives the first conveying roller 28 to move downward through the second L-shaped plate 27. When the first L-shaped plate 32 moves downward, the first wedge block 43 does not squeeze the wedge plate 36. At this time, under the elastic force of the plurality of third springs 37, the wedge plate 36 moves to the left. At this time, under the elastic force of the plurality of second springs 40, the second wedge block 44 drives the raised plate 39 to move upward through the slide plate 42, increasing the lower end of the raised plate 39 and the aroma cloth body 4. The distance between the upper ends, when the first plate 6 is subsequently moved, the squeezing roller 41, under the squeezing effect of the raised plate 39, will drive the first shaped plate 7 and the laser cutting head 8 to move downward, so that the distance between the laser cutting head 8 and the aroma cloth body 4 is longer. In this way, the height of the laser cutting head 8 can be automatically adjusted according to the thickness of the aroma cloth body 4, avoiding the problem that the height of the laser head in the prior art is fixed, resulting in incomplete cutting of the aroma cloth or overheating and burning of the cutting edge when cutting aroma cloths of different thicknesses; Then, the first motor 15 is started to rotate counterclockwise, and the laser cutting head 8 is started. At this time, the fixing ring drives the outer ring side wall of the first one-way bearing 16 to rotate counterclockwise, and the outer ring side wall of the first one-way bearing 16 drives its inner ring to rotate, driving the first reciprocating screw 14 to rotate counterclockwise, and driving the first plate 6 to move. During the movement of the first plate 6, the squeezing roller 41, under the squeezing effect of the raised plate 39, drives the first shaped plate 7 and the laser cutting head 8 to move downward, and adjusts the distance between the laser cutting head 8 and the fragrance cloth body 4, so as to complete the laser cutting of the fragrance cloth body 4; When the first reciprocating screw 14 rotates counterclockwise, the second reciprocating screw 24 is driven to rotate by the third wheel 25, the synchronous belt and the fourth wheel 26, and the second plate 21 and the scraper 23 are driven to move. At this time, the scraper 23 can scrape off some carbonized materials adhering to the surface of the lower surface of the two supporting plates 12 due to laser cutting, so as to avoid the existence of carbonized materials that easily cause wrinkles in the subsequent cloth conveying process; It should be noted that when the aromatic cloth body 4 is cut, the first plate 6 and the second plate 21 are both moved once, that is, after the first plate 6 and the second plate 21 are moved, the first plate 6 is located at the edge of the first reciprocating screw 14, and the second plate 21 is located at the edge of the second reciprocating screw 24, which will not affect the subsequent movement of the first plate 6 and the second plate 21, and at this time, the laser cutting head 8 and the second plate 21 are both away from the aromatic cloth body 4 and the carrying plate 12; After cutting, the laser cutting head 8 and the second plate 21 are away from the aromatic cloth body 4 and the carrying plate 12, and then the first motor 15 is started to rotate clockwise. At this time, the inner ring of the second one-way bearing 17 drives its outer ring to rotate, and then drives the two first rods 11 to rotate clockwise through the first wheel 18, the synchronous belt and the two second wheels 19, and drives the two carrying plates 12 to rotate half a circle clockwise, which not only automatically flows out the cut aromatic cloth body 4 into the receiving box 13, but also can replace the cutting surfaces of the two carrying plates 12, which is convenient for the subsequent cleaning of the cutting surfaces of the carrying plates 12, and then repeats the above steps to cut a whole sheet of aromatic cloth into multiple small-area cloths of desired shapes.

[0039] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
