Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a laser cutting machine for wrinkle-free fabrics. Background Art

[0002] Non-iron fabric, also known as permanent wrinkle fabric or easy-care fabric, refers to fabric that can maintain a certain shape stability after special treatment, is not prone to wrinkles, and can easily restore to flatness after encountering wrinkles. Non-iron fabric includes coated non-iron fabric. Coated non-iron fabric refers to a layer of special coating applied on the surface of ordinary fabric, which makes it waterproof, oil-proof, wrinkle-resistant and other properties on the basis of reducing costs. Coated non-iron fabric is generally cut by laser cutting. When cutting the fabric, the cutting trajectory is generally a straight line or an arc with a large curvature.

[0003] When the existing laser cutting device cuts the coated wrinkle-free fabric, the laser beam will irradiate the surface of the fabric, thereby cutting the fabric. The laser beam will generate more heat when cutting the fabric, causing the coating at the cutting point of the fabric to melt. After the coating cools down, it will cause uneven burrs to appear at the cutting point of the fabric, and there will be no coating on the side of the fabric after cutting, which reduces the quality of the fabric. The existing fabric is generally fixed by a number of buckles. When the laser cutting head cuts the fabric, the tension of the fabric at the cutting point will be reduced, which will easily cause wrinkles on the fabric, reducing the quality of laser cutting.

[0020] In this embodiment, the cutting and trimming mechanism 2 includes a first limiting groove 25 opened at the upper end of the main body plate 1, and a first empty groove 26 in contact with the first limiting groove 25 is opened at the upper end of the main body plate 1.

[0021] A second limiting groove 210 is opened at the lower end of the first fixed body 21, and a third motor 222 is fixedly connected in the second limiting groove 210. The transmission shaft end of the third motor 222 is fixedly connected in the second limiting groove 210 with a second threaded rod 211. The side of the second threaded rod 211 is provided with a second limiting body 212 through threaded cooperation, and the side of the second limiting body 212 is slidably cooperated with the second limiting groove 210.

[0022] A third slot 216 is provided at the lower end of the second limiting body 212, and a second motor 217 is fixedly connected to the second limiting body 212 in the third slot 216. A third electric telescopic rod 218 is fixedly connected to the transmission shaft end of the second motor 217, and a pressure sensor 219 is fixedly connected to the telescopic end of the third electric telescopic rod 218. The lower end of the pressure sensor 219 is fixedly connected to a second fixed body 220, and the lower end of the second fixed body 220 is an open structure, and a pressure wheel 221 is rotatably connected to the lower end opening structure of the second fixed body 220.

[0023] The side surface of the pressing wheel 221 is a rotating body structure with radius gradually increasing towards the center line at both ends, and the cross section of the second fixed body 220 is smaller than the cross section of the third slot 216 .

[0024] A second slot 213 is formed at the lower end of the second limiting body 212, and a second electric telescopic rod 214 is fixedly connected to the second limiting body 212 in the second slot 213. A laser cutting head 215 for cutting coated wrinkle-free fabrics is fixedly connected to the telescopic end of the second electric telescopic rod 214.

[0025] A first motor 28 is fixedly connected to the side surface of the main body plate 1 at a position close to the first limiting groove 25, and a transmission shaft end of the first motor 28 is fixedly connected to a first threaded rod 24 in the first limiting groove 25, and a side surface of the first threaded rod 24 is threadedly matched with the first limiting body 22.

[0026] The upper end of the main body plate 1 is provided with a slide groove 29 at a position close to one side, and the lower end of the first fixed body 21 is fixedly connected with a third fixed body 223 at a position close to the slide groove 29.

[0027] Specifically, the second electric telescopic rod 214 extends, driving the laser cutting head 215 to perform laser cutting on the surface of the cloth. During cutting, the cutting trajectory is generally a straight line or an arc with an arc angle. Therefore, after the second limiting body 212 drives the laser cutting head 215 to cut, the second limiting body 212 continues to drive the second motor 217 to the cutting area. At the same time, the second motor 217 drives the third electric telescopic rod 218 to rotate, so that the pressure wheel 221 at the telescopic end of the third electric telescopic rod 218 rotates to the same angle as the moving trajectory of the second limiting body 212. In the process of the pressure wheel 221 supporting the cloth to rotate, since the side surface of the pressure wheel 221 is an arc surface gradually expressed toward the center radius at both ends, the melted coating can be extruded toward the cloth, so that the melted coating re-covers the side surface of the cloth where the cut is located.

[0028] In this embodiment, a fixing mechanism 3 for supporting the cutting area of ​​the coated non-ironing fabric is fixedly connected to the side surface of the first limiting body 22 .

[0029] The fixing mechanism 3 includes four fourth empty slots 31 symmetrically opened at the upper end of the main body plate 1, and fourth electric telescopic rods 32 are fixedly connected in the four fourth empty slots 31 respectively, and the telescopic ends of two adjacent fourth electric telescopic rods 32 are fixedly connected to a pressing plate 33, and the upper end of the main body plate 1 is fixedly connected to an anti-skid plate 34 below the two pressing plates 33.

[0030] Specifically, the four fourth electric telescopic rods 32 are retracted at the same time, and the four fourth electric telescopic rods 32 drive the two pressing plates 33 to move downward, and the pressing plates 33 and the anti-slip plate 34 squeeze and fix the end surface of the fabric.

[0031] In this embodiment, a support mechanism 4 for clamping and limiting the coated wrinkle-free fabric is provided at the upper end of the main body plate 1 .

[0032] The supporting mechanism 4 includes a fourth fixed body 41 fixedly connected to the side of the first limiting body 22, a fifth slot 42 is provided at the center of the upper end of the fourth fixed body 41, a plurality of through holes 43 are symmetrically provided at the upper end of the fourth fixed body 41, two cavities 44 communicating with the plurality of through holes 43 are provided inside the fourth fixed body 41, two air pipes 45 communicating with the cavities 44 are fixedly connected to the lower end of the fourth fixed body 41, the two air pipes 45 are communicated with an external air pump, and the length of the fourth fixed body 41 is the same as the width of the first slot 26 at the upper end of the main plate 1.

[0033] The lower end of the fourth fixing body 41 is fixedly connected to a supporting column 27 . The lower end of the supporting column 27 is a rounded structure. The lower end of the supporting column 27 is in contact with the main plate 1 .

[0034] Specifically, the fourth fixed body 41 moves along with the first limiting body 22, the upper end of the fourth fixed body 41 contacts the cloth, and the fourth fixed body 41 is a heat-conducting material, which can quickly cool the cloth. At the same time, the air pipe 45 is connected to the air pump, and the air pipe 45 is connected to a plurality of through holes 43 through the cavity 44. Slow air suction is performed through the through holes 43, which can provide a smaller suction effect for the cloth.

[0035] When in use, the lower end of the main plate 1 is placed on a horizontal plane. First, the square coated non-ironing fabric to be cut is placed on the upper end of the main plate 1 through the first fixed body 21 and the fourth fixed body 41. Then, the four fourth electric telescopic rods 32 are retracted at the same time. The four fourth electric telescopic rods 32 drive the two pressing plates 33 to move downward. The pressing plates 33 and the anti-slip plate 34 squeeze and fix the end surface of the fabric. Then, the first motor 28 is started. The first motor 28 drives the first threaded rod 24 to rotate. The first threaded rod 24 cooperates to drive the first limiting body 22 to move along the first limiting groove 25. While the first limiting body 22 moves, the third motor 222 is started. The third motor 222 drives the second threaded rod 211 to rotate. The second threaded rod 211 cooperates to drive the second limiting body 212 to move along the second limiting groove 210, thereby driving the second limiting body 212 to move to any position above the fabric. Then, the second electric telescopic rod 214 extends, driving the laser cutting head 215 to The surface of the fabric is laser cut. While moving, the pulley 224 of the third fixed body 223 at the lower end of the first fixed body 21 rolls with the slide groove 29, which can increase the supporting force for the first fixed body 21 and improve the stability of the device. During cutting, the cutting trajectory is generally a straight line or an arc with an arc angle. Therefore, after the second limiting body 212 drives the laser cutting head 215 to cut, the second limiting body 212 continues to drive the second motor 217 to the cutting area. At the same time, the second motor 217 drives the third electric telescopic rod 218 to rotate, so that the pressure wheel 221 at the telescopic end of the third electric telescopic rod 218 rotates to the same angle as the moving trajectory of the second limiting body 212. In the process of the pressure wheel 221 supporting the fabric to rotate, since the side of the pressure wheel 221 is an arc surface gradually expressed toward the center radius at both ends, the melted coating can be extruded toward the fabric, so that the melted coating re-covers the side of the fabric where the fabric is cut, thereby improving the performance of the non-ironing fabric after cutting.

[0036] During the process of the laser cutting head 215 cutting the fabric and the pressure wheel 221 trimming the cut fabric, the fourth fixed body 41 moves along with the first limiting body 22, the upper end of the fourth fixed body 41 contacts the fabric, and the fourth fixed body 41 is a heat-conducting material, which can quickly cool the fabric. At the same time, the air supply pipe 45 is connected to the air pump, and the air supply pipe 45 is connected to a plurality of through holes 43 through the cavity 44. Slow air suction is performed through the through holes 43, which can provide a smaller suction effect for the fabric. When the laser cutting head 215 cuts the fabric, the connection force between the cut fabric and the previous fabric disappears. At this time, the through holes 43 can provide a suction force for the cut fabric, thereby preventing the fabric from shifting during the continuous cutting process of the laser cutting head 215, preventing fabric wrinkles, and improving the quality of the cut fabric.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
