Especially in the sofa manufacturing industry, laser cutting machines have become an indispensable equipment. There are various types of sofa fabrics, including polyester, cotton, linen and other materials. These fabrics need to be precisely cut before use to meet the needs of sofa design. Traditional mechanical tool cutting methods have some shortcomings, such as slow cutting speed, low precision and limited processing capabilities for complex patterns. Laser cutting machines can achieve fast and accurate cutting of various materials by using high-energy laser beams to replace traditional tools. At the same time, they can effectively reduce material waste and improve production efficiency.

The conveying net 201 on the laser cutting machine 2 is used to support the fabric to be laid flat and to convey the fabric to move. When the fabric is laid on the conveying net 201, the laser on the laser cutting machine 2 can be used to automatically cut the fabric, so that the fabric is cut into a desired shape. After the fabric is cut, the conveying net 201 on the laser cutting machine 2 conveys the cut fabric, so that the cut fabric is discharged and the next section of the fabric is prepared for cutting.

When the fabric in the feeding mechanism is conveyed to the conveying net 201 between the electric roller Ⅰ5 and the electric roller Ⅱ7, the rotating sponge strip 8 is used to push the wrinkles in the middle area of ​​the fabric to both sides, so that the wrinkles in the middle area of ​​the fabric can be prevented from affecting the subsequent cutting; telescopic short rods 9 are symmetrically arranged on the laser cutting machine 2, and the number of the telescopic short rods 9 is four. The upper end of the telescopic short rod 9 is connected to the inner wall of the laser cutting machine 2, and the lower end of the telescopic short rod 9 is connected There is a sliding frame 10 with a hollow structure, and the telescopic short rod 9 and the sliding frame 10 are both located on the inner side of the conveying net 201; a spring 11 is arranged between the upper end of the telescopic short rod 9 and the sliding frame 10; cones 12 are arranged at intervals at the bottom of the sliding frame 10, and the cones 12 extend into the grid of the conveying net 201, so that the cones 12 can squeeze out the fine fabrics stuck on the conveying net 201, thereby preventing the fine fabrics from remaining on the conveying net 201; the blowing mechanism is used to blow off the fine fabrics adhered to the conveying net 201.

[0034] See also Figure 4 and Figure 5 As shown, the blowing mechanism includes an air pump Ⅰ13 and an air pipe Ⅰ14; the two air pumps Ⅰ13 are symmetrically arranged on the inner wall of the laser cutting machine 2, and the two air pumps Ⅰ13 are both located on the inner side of the conveying net 201; two air outlet holes 1301 are opened at the bottom of the sliding frame 10, and the air outlet of the air pump Ⅰ13 is connected with the sliding frame 10 through the air pipe Ⅰ14, so that the air pump Ⅰ13 can draw external air into the sliding frame 10, so that the air in the sliding frame 10 is blown from the air outlet holes 1301 to the conveying net 201, and then the fine fabrics adhered to the conveying net 201 are blown off.

[0035] See also Figure 6As shown, the feeding mechanism includes a support frame 15, a servo motor 16 and a friction wheel 17; the two support frames 15 are symmetrically arranged at the upper left side of the laser cutting machine 2, and the support frame 15 is provided with a Y-shaped structure for placing a reel with fabric wound around it; the support frame 15 is connected to the servo motor 16; the output shaft of the servo motor 16 is connected to the friction wheel 17, and the friction wheel 17 is driven to rotate by the servo motor 16, so that the friction wheel 17 drives the reel with fabric wound around it to rotate through the friction force, thereby unwinding the fabric on the reel.

[0036] When in use, place the roll with fabric wound around it between the Y-shaped structures of the two support frames 15, place the front and rear ends of the rotating shaft in the middle of the roll on the Y-shaped structures respectively, and make the outer wall of the rotating shaft in the middle of the roll contact with the friction wheel 17, then pull the leading end of the fabric to move to the right from the top of the support platform 3 until the leading end of the fabric passes between the electric roller Ⅰ5 and the electric roller Ⅱ7 and reaches the top surface of the conveying net 201, then slowly release the leading end of the fabric so that the leading end of the fabric contacts the top surface of the conveying net 201, and the bottom surface of the fabric contacts the sponge strip 8 on the electric roller Ⅰ5, then drive the electric roller Ⅱ7 to move downward through the electric push rod Ⅰ6 until the sponge strip 8 on the electric roller Ⅱ7 contacts the top surface of the fabric, and then convey the leading end of the fabric through the conveying net 201 on the laser cutting machine 2 Move to the right until the conveying net 201 on the laser cutting machine 2 conveys the head end of the fabric to the specified position, and at the same time drives the friction wheel 17 to rotate through the servo motor 16, so that the friction wheel 17 drives the roll with the fabric to rotate through the friction force, thereby unwinding the fabric on the roll, and at the same time controls the electric roller Ⅰ5 to rotate counterclockwise and the electric roller Ⅱ7 to rotate clockwise, so that the sponge strips 8 on the electric rollers Ⅰ5 and Ⅱ7 move the wrinkles in the middle area of ​​the fabric to the front and rear sides, so as to eliminate the wrinkles in the middle area of ​​the fabric, thereby preventing the wrinkles in the middle area of ​​the fabric from affecting the subsequent laser cutting. During the operation of the conveying net 201 on the laser cutting machine 2, the outside air is drawn in through the air pump Ⅰ13 In the sliding frame 10, the air in the sliding frame 10 can be blown from the air outlet 1301 to the conveying net 201, so that the fine fabrics adhered to the conveying net 201 are blown off, and when the conveying net 201 contacts the cone 12, the conveying net 201 will squeeze the cone surface of the cone 12, so that the cone 12 and the sliding frame 10 move upward, the telescopic short rod 9 contracts, and the spring 11 is compressed. When the conveying net 201 is separated from the cone 12, the spring 11 returns to its original state, and the spring 11 drives the telescopic short rod 9 to extend, so that the cone 12 and the sliding frame 10 move downward and reset, so that the cone 12 re-extends into the grid of the conveying net 201, so that the cone 12 can squeeze out the fine fabrics stuck on the conveying net 201, thereby preventing the fine fabrics from being stuck. The remaining fabric remains on the conveyor net 201. When the conveyor net 201 on the laser cutting machine 2 conveys the fabric to the specified position, the servo motor 16 stops driving the friction wheel 17 to rotate, and the electric roller Ⅰ5 and the electric roller Ⅱ7 are controlled to stop rotating. Then the laser cutting machine 2 uses laser to cut the fabric into the required shape (usually, in order to ensure the quality, only the middle area of ​​the fabric is cut into the required shape, and the front and back sides are used as waste). After the fabric is cut, the above-mentioned operation of conveying the fabric by the conveyor net 201 is repeated, so that the conveyor net 201 continues to convey the cut fabric and the remaining waste to the right. After that, the cut fabric is taken away from the conveyor net 201 manually.The next section of fabric to be cut is transported to a designated location through the conveyor net 201, and the operation is repeated to repeatedly cut the fabric into a desired shape; When all the fabrics on the roll are cut, the empty roll is removed from the Y-shaped structure of the two support frames 15, and then the electric push rod I6 drives the electric roller II7 to move upward and reset.

[0038] By providing the connecting frame Ⅰ18 and the screen frame 19, the fine fabrics squeezed and blown off the conveying net 201 can be made to fall downward through the connecting frame Ⅰ18 into the screen frame 19, so that the screen frame 19 can collect the fine fabrics. After that, the operator only needs to pull the screen frame 19 forward to process the fine fabrics in the screen frame 19. After the fine fabrics in the screen frame 19 are processed cleanly, the screen frame 19 can be pushed back into the connecting frame Ⅰ18.

[0039] See also Figure 7-Figure 9 As shown, it also includes a discharging mechanism, and the centralized mechanism includes a connecting frame Ⅱ20, a discharging hopper 21 and an electric roller III22.

By designing in this way, it is possible to prevent the closed frame 23 from leaking. The pipe opening of this section of the connecting pipe 26 in the closed frame 23 is wrapped by the fabric; a filter screen 27 is provided at the pipe opening of this section of the connecting pipe 26 in the closed frame 23, and the filter screen 27 is used to prevent the fabric from being sucked into the connecting pipe 26 to avoid clogging inside the connecting pipe 26; an electric slide rail 28 is installed on the upper right side of the connecting frame II 20, and three sliders are provided on the electric slide rail 28; a suction pipe 29 is provided through the three sliders of the electric slide rail 28, one end of the suction pipe 29 faces the conveying net 201 and is used to suck away the fabric, and the other end of the suction pipe 29 is connected to the closed frame 23, so that the suction pipe 29 can suck the fabric into the closed frame 23 for collection; a collection frame 30 for collecting fabrics is placed at the bottom of the closed frame 23, so that subsequent operators can centrally process the fabrics.

[0042] When the cut fabric needs to be taken away from the conveying net 201 manually, the electric slide rail 28 can be used to drive one end of the suction pipe 29 to move, so as to adjust the direction of one end of the suction pipe 29 so that one end of the suction pipe 29 is directed toward the cut fabric on the conveying net 201, and then the air pump III 25 is used to evacuate the closed frame 23 through the connecting pipe 26 to form a negative pressure in the closed frame 23, so that the closed frame 23 sucks the cut fabric on the conveying net 201 through the suction pipe 29, so that the cut fabric is sucked out through the suction pipe 29.

Then, the electric push rod Ⅲ33 is used to drive the connecting frame Ⅱ34 to move downward until the bottom of the connecting frame Ⅱ34 contacts with the head end of the fabric. Then, the air pump Ⅱ35 is used to evacuate the inside of the connecting frame Ⅱ34 through the air pipe Ⅱ36 to form a negative pressure in the connecting frame Ⅱ34, so that the head end of the fabric is adsorbed through the vent 3401 in the connecting frame Ⅱ34. Then, the electric push rod Ⅲ33 is used to drive the connecting frame Ⅱ34 to move upward. The connecting frame Ⅱ34 is automatically reset, and then the electric push rod Ⅱ31 drives the connecting frame Ⅲ32, the electric push rod Ⅲ33 and the connecting frame Ⅱ34 to move right and reset, so that the connecting frame Ⅱ34 absorbs the head end of the fabric and moves right, until the head end of the fabric is driven to move right from the top of the support platform 3 to the top of the conveying net 201, and then the electric push rod Ⅲ33 drives the connecting frame Ⅱ34 to move downward, so that the connecting frame Ⅱ34 drives the head end of the fabric to contact the conveying net 201, and then the ventilation valve 37 is opened to ventilate the connecting frame Ⅱ34, so that the air pressure in the connecting frame Ⅱ34 is restored, thereby loosening the head end of the fabric in the connecting frame Ⅱ34, and then the electric push rod Ⅲ33 drives the connecting frame Ⅱ34 to move upward and reset, so that the connecting frame Ⅱ34 is separated from the head end of the fabric, and then the ventilation valve 37 is closed. In this way, the head end of the fabric can be automatically pulled onto the conveying net 201 for laying.
