[0044] Processing mechanism 5, which is used to cut sofa fabric, is installed in the middle of gantry frame 3;

[0045] The processing mechanism 5 comprises a cylindrical barrel 51, both ends of the cylindrical barrel 51 are rotatably installed at positions corresponding to the inner side of the gantry 3, the edges of both ends of the cylindrical barrel 51 are fixedly installed with a poking tooth 52, the outer circular surface of the cylindrical barrel 51 is fixedly installed with anti-skid protruding blocks 53, a one-word-shaped hole 54 is formed in the middle of the bottom of the outer circular surface of the cylindrical barrel 51, the top of the inner cavity of the cylindrical barrel 51 is fixedly installed with an electric telescopic rod 55, the output end of the electric telescopic rod 55 is fixedly installed with a cutting blade 56, the position of the cutting blade 56 corresponds to the position of the one-word-shaped hole 54, the bottom of the outer circular surface of the cylindrical barrel 51 and close to the position of the one-word-shaped hole 54 is installed with a tensioning assembly 57, the staff starts the servo motor 4 to work, the output end of the servo motor 4 is rotated to drive the cylindrical barrel 51 to rotate, when the one-word-shaped hole 54 is rotated to the top of the strip-shaped hole 2, the work of the servo motor 4 is paused, the output end of the electric telescopic rod 55 is extended to push the cutting blade 56 downward, so that the cutting edge at the bottom of the cutting blade 56 passes through the one-word-shaped hole 54 and extends into the strip-shaped hole 2, and under the interaction between the cutting blade 56 and the inner wall of the strip-shaped hole 2, and combined with the inclined cutting edge at the bottom of the cutting blade 56, the cutting blade 56 cuts the sofa fabric in the form of scissors;

[0046] When the sofa fabric cutting is completed, the output end of the electric telescopic rod 55 is retracted to lift the cutting blade 56, and the cutting blade 56 is retracted into the inside of the cylindrical barrel 51;

[0047] The cylindrical barrel 51 and the servo motor 4 are installed at the same height, so that the output end of the servo motor 4 drives the cylindrical barrel 51 to rotate, and the anti-skid protruding blocks 53 are uniformly distributed on the outer circular surface of the cylindrical barrel 51.

[0048] The poking tooth 52 is arc-shaped, the poking tooth 52 is uniformly distributed on the edges of both ends of the cylindrical barrel 51, and the cutting edge at the bottom of the cutting blade 56 is inclined, so as to cut the sofa fabric in the form of scissors.

[0049] When the cylindrical barrel 51 rotates, the anti-skid protruding blocks 53 are rotated to the bottom to contact the sofa fabric to be cut on the top of the rack 1, and as the cylindrical barrel 51 continues to rotate, the sofa fabric is subjected to a poking force towards the cylindrical barrel 51, so as to automatically feed the sofa fabric for continuous cutting.

[0050] The tensioning assembly 57 includes a guide rod 571, which is slidably mounted on the bottom of the outer surface of the cylindrical tube 51 and near the slotted hole 54. The guide rod 571 is installed at an angle, and a circular plate 572 is fixedly mounted on the top end of the guide rod 571. The circular plate 572 is installed inside the cylindrical tube 51, and a pressure bar 573 is fixedly mounted on the bottom end of the guide rod 571. A spring 574 is fixedly mounted between the bottom of the circular plate 572 and the bottom of the inner cavity of the cylindrical tube 51. When the cylindrical tube 51 rotates, the tensioning assembly 57... The entire unit rotates together with the cylindrical tube 51. The bottom of the pressure bar 573 contacts the sofa fabric, and under the sliding guidance of the guide rod 571, the spring 574 is stretched.

[0051] The guide rod 571 passes through the center of the spring 574, and the spring 574 is not easy to bend when stretched. There are two pressure rods 573, and the two pressure rods 573 are symmetrically installed along the straight hole 54, which makes it easy for the symmetrical pressure rods 573 on both sides to tension the sofa fabric.

[0052] Second embodiment, such as Figures 1-7 As shown, based on the first embodiment:

[0053] A pretreatment mechanism 6 is installed at the top of the frame 1 and near the cylindrical tube 51. The pretreatment mechanism 6 includes a frame 61. The bottom of the frame 61 is fixedly installed at the side of the top of the frame 1. A connecting slider 62 is slidably installed on the outside of the frame 61 and near the top. A force-bearing rod 63 is fixedly installed on the top of the connecting slider 62 and near the actuating tooth 52. A reset elastic strip 64 is fixedly installed between the outside of the connecting slider 62 and the outside of the frame 61. An arched scraper 65 is fixedly installed at the bottom of the connecting slider 62 through a bend rod. A rolling pressure roller 66 is rolled inside the arched scraper 65. The sofa fabric passes through the bottom of the arched scraper 65 and contacts the sofa fabric through the bottom edge of the arched scraper 65, which can flatten the sofa fabric and prevent wrinkles. At the same time, the rolling pressure roller 66 rolls and presses the sofa fabric.

[0054] There are two frames 61, and the two frames 61 are symmetrically installed along the arched scraper 65. The end of the force rod 63 away from the connecting slider 62 is arc-shaped. The rolling pressure roller 66 is installed in the middle of the arched scraper 65. As the cylindrical tube 51 drives the actuating tooth 52 to rotate in a circle, the actuating tooth 52 contacts the force rod 63.

Under the sliding connection of the connecting slider 62, the entire arched scraper 65 is driven to move away from the cylindrical tube 51, and the reset elastic strip 64 is compressed.

[0055] When the actuating tooth 52 separates from the force-bearing rod 63, the actuating force on the force-bearing rod 63 disappears. Under the elastic force of the reset elastic strip 64, the connecting slider 62 drives the arched scraper 65 to move in the opposite direction to reset.
