Abstract
Description
Technical Field
[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to an ultrasonic sewing device for nonwoven fabrics. Background Technology
[0002] Chinese patent application number 202420978657.4 discloses an ultrasonic heat sealing device for non-woven fabric. The device involves rotating a disc, which drives a ball screw to rotate. The nut on the ball screw moves linearly. The position of the limiting plate is precisely adjusted according to the values on the scale. Once the desired position is reached, the limiting plate is rotated towards the work platform. When the limiting plate reaches the top of the work platform, one side of the non-woven fabric is placed against the outer wall of the limiting plate. The sealing edge of the non-woven fabric is positioned on one side of the pattern wheel. The non-woven fabric is pressed down with the palm and pushed along the limiting plate, conveying it to the top of the high-frequency oscillating welding head. The foot pedal on the machine body is pressed down, causing the ultrasonic vibrator to vibrate and transmit the vibration to the high-frequency oscillating welding head. The high-frequency oscillating welding head transmits ultrasonic waves to the non-woven fabric, causing it to heat-melt. After the pattern wheel rotates, the heat-melted area is pressed together, achieving edge sealing of the non-woven fabric.
[0003] The comparative document requires adjusting the dimensions according to a ruler to define the position of the non-woven fabric, then pressing and pushing the fabric forward by hand, and activating the ultrasonic vibrator by stepping on the platform. This sewing equipment, which requires full manual operation, is inefficient, and prolonged work can lead to inaccurate fabric movement, resulting in incorrect sewing dimensions and affecting product quality.
[0004] Therefore, how to improve the effective load capacity of a nonwoven ultrasonic sewing device is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a nonwoven ultrasonic sewing device to improve the sewing efficiency of such a nonwoven ultrasonic sewing device.

[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0038] Please refer to Figures 1 to 8 The present invention discloses an ultrasonic sewing device for nonwoven fabric, comprising: an unwinding roller 2 mounted on a frame 1;
[0039] Tensioning roller 201 is located at the output end of unwinding roller 2;
[0040] The ultrasonic suturing device 3 and the second ultrasonic suturing machine 606 are located at the output end of the tension roller 201. The ultrasonic suturing device 3 includes a rotating rod 301, on which the first ultrasonic suturing machine 302 and the limiting roller 303 are mounted.
[0041] In this application, both the first cutting roller 4 and the second cutting roller 401 are equipped with gears. The second cutting roller 401 is rotated by a motor, and the gears on the first cutting roller 4 drive the first cutting roller 4 to rotate. The gears drive the first cutting roller 4 to rotate.
[0042] The winding device 7 has two conveyor rollers 8 installed on one side. In this application, one of the conveyor rollers 8 is driven to rotate by a motor, and the other conveyor roller 8 is driven to rotate by a gear, which in turn drives the other conveyor roller 8 to rotate.
[0043] The cross-cutting device 5 includes a cutting blade 501, and a cutting plate 502 is installed below the cutting blade 501. The cutting plate 502 has a cutting groove 503 corresponding to the cutting blade 501.
[0044] Pulling device 6 includes a base plate 601. A movable cover 602 is installed on the top of the base plate 601. A cylinder gripper 607 is installed on one end of the cover 602 near the cross-cutting device 5. The cylinder gripper 607 is opened and closed by a cylinder, and the cover 602 is pushed by a cylinder.
[0045] A leather valve plate 603 is installed inside the base plate 601. The leather valve plate 603 is fixedly connected to the movable cover 602 via a connecting rod 604. Several air holes 605 are opened on the top of the base plate 601.
[0046] A conveyor belt 504 is installed at one end of the cutting plate 502. A protrusion 505 is installed on the cutting blade 501. The cutting blade 501 is connected to a pressure plate 506 through the protrusion 505. A slide rail 507 is installed on the pressure plate 506. A spring block 512 is installed inside the slide rail 507. An installation plate 511 is installed on the other side of the conveyor belt 504. A through groove 508 separates the installation plate 511 from the base plate 601.
[0047] A channel 509 is provided at the bottom of the channel 508, and a collection box 510 is installed at the bottom of the channel 509.
[0048] The winding device 7 includes a frame 701, which is mounted on a support frame 702. A winding roller 703 and a screw 704 are mounted on the frame 701, and an auxiliary component 705 is mounted on the screw 704.
[0049] The first cutting roller 4 is located above the second cutting roller 401. A cutting ring 402 is installed on the first cutting roller 4, and an annular groove 403 is provided on the second cutting roller 401.
[0050] Both the first ultrasonic sewing machine 302 and the limiting roller 303 are equipped with support seats 304. The ultrasonic sewing device 3 in this application uses high-frequency oscillation to transmit sound waves from the welding head to the welding surface of the workpiece, instantly causing friction between the molecules of the workpiece, reaching the melting point of the plastic, thereby completing the rapid dissolution of the solid material and completing the welding. When the folded non-woven fabric passes between the support seat 304 and the first ultrasonic sewing machine 302, the motor drives the rotating rod 301 to rotate, and the rotating rod 301 drives the first ultrasonic sewing machine 302 and the limiting roller 303 to rotate, and the first ultrasonic sewing machine 302 sews the non-woven fabric.
[0051] The first cutting roller 4 and the second cutting roller 401 rotate via two gears, and the first cutting roller 4 rotates via a motor.
[0052] The second ultrasonic suture device is installed above the base plate, and the second ultrasonic suture device 606 is driven by a motor.
[0053] The first rotating roller 101, the second rotating roller 102 and the third rotating roller 103 are installed sequentially on the frame 1.
[0054] like Figure 1As shown, in this application, the folded nonwoven fabric roll is placed into the unwinding roller 2, and then unwound. The folded nonwoven fabric is then manually conveyed through the first rotating roller 101, the tensioning roller 201, and the second rotating roller 102. The folded nonwoven fabric is then placed on two support seats 304. At this point, the side of the nonwoven fabric to be sewn is directly below the first ultrasonic sewing machine 302, and the folded side is below the limiting roller 303. The motor is started, driving the rotating rod 301 to rotate. The rotating rod 301 drives the first ultrasonic sewing machine 302 and the limiting roller 303 to rotate. The first ultrasonic sewing machine 302 then sews the nonwoven fabric. Simultaneously, the nonwoven fabric is manually pulled through the third rotating roller 103 and then fed between the first cutting roller 4 and the second cutting roller 401. The motor is then started, driving the second cutting roller 401 to rotate. The second cutting roller 401 drives another gear through a gear, and the other gear then drives the first cutting roller 401 to rotate. As roller 4 rotates, the first cutting roller 4, through the cooperation of the cutting ring 402 and the annular groove 403, performs edge trimming on the sewn nonwoven fabric. At this time, the nonwoven fabric is divided into two parts: one part is the cut nonwoven fabric, and the other part is the sewn nonwoven fabric. The cut nonwoven fabric passes through the auxiliary component 705 and is then fixed on the winding roller 703. The winding roller 703 and the screw 704 rotate simultaneously. The winding roller 703 winds up the cut nonwoven fabric, and the screw 704 drives the auxiliary component 705 to move back and forth, making the winding roller 703 wind up more neatly. The sewn nonwoven fabric passes through two conveying rollers 8. While the cut nonwoven fabric is being wound up by the winding roller 703, the auxiliary component 705 drives the cut nonwoven fabric to move left and right. The winding roller 703 winds up the nonwoven fabric, and the nonwoven fabric will be wound up in sequence from right to left and then from left to right along the surface of the winding roller 703. In this way, the wound nonwoven fabric is more flat and orderly.
[0055] Two conveyor rollers 8 transport the sewn nonwoven fabric to the cutting plate 502, and then the nonwoven fabric is transported to the conveyor belt 504, as shown below. Figure 2As shown, at this time, the cylinder starts, driving the cutting blade 501 to descend. The cutting blade 501 moves downward within the slide rail 507 via the protrusion 505, simultaneously pressing down the spring block 512, which in turn drives the pressure plate 506 to descend. The pressure plate 506 presses the non-woven fabric firmly. At this time, the cutting blade 501 continues to move downward via the cylinder. Simultaneously, the spring block 512 is under pressure and moves downward via the spring until the cutting blade 501 completes the cutting of the non-woven fabric. The spring block 512 then stops moving, and the cut non-woven fabric is conveyed by the conveyor belt 504. When the cutting blade 501 drives the pressure plate 506 downward via the spring block 512, there is no support point below the pressure plate 506, so the spring block 512 will not experience significant pressure and will not move completely downward. When the pressure plate 506 presses down on the non-woven fabric on the cutting plate 502, the cutting plate 502 becomes the support point for the pressure plate 506. At this time, the cutting blade 501 moves downward, and the spring block 512... When the nonwoven fabric is conveyed to the end of the mounting plate 511, it will be under pressure. The spring block 512 will start to move downward through the spring. At this time, the moving cover is located at the end and clamps the nonwoven fabric through 607. The cylinder is started to drive the moving cover 602 to move to the right. The cylinder jaws 607 close to clamp the nonwoven fabric. The moving cover 602 drives the cylinder jaws 607 and the nonwoven fabric to move to the right. When the nonwoven fabric moves to the bottom plate 601, the cylinder stops moving. The cylinder drives the second ultrasonic sewing machine 606 to descend and sew the other end of the nonwoven fabric. When the moving cover 602 moves to the right, it drives the leather valve plate 603 to move to the right through the connecting rod 604. When the leather valve plate 603 moves to the right, it discharges the air hole into the bottom plate 601 through the through hole. At this time, the air hole 605 starts to suck air into the bottom plate 601. At the same time as sucking air, it will adsorb and fix the nonwoven fabric. The adsorption and fixation of the nonwoven fabric is to ensure that the nonwoven fabric can be stably sewn when the second ultrasonic sewing machine 606 sews, and to prevent displacement.
[0056] like Figure 8 As shown, after the nonwoven fabric is sewn, the second ultrasonic sewing machine 606 rises, the cylinder starts and pushes the moving cover 602 to the left. The moving cover 602 drives the cylinder gripper 607 and the connecting rod 604 to move. The connecting rod 604 drives the valve plate 603 to move to the left, and the air hole 605 releases air. The nonwoven fabric is no longer attracted. At the same time, the moving cover 602 pushes the cylinder gripper 607 and the nonwoven fabric to move. When the cylinder gripper 607 moves above the channel 508, the cylinder gripper 607 opens. At this time, the nonwoven fabric falls down and falls into the collection box 510 along the through groove 508 and the channel 509. After the nonwoven fabric falls down, the cylinder drives the moving cover 602 to move to the right. The cylinder gripper 607 resets and clamps the nonwoven fabric, and then drives the nonwoven fabric to move for sewing. The above steps are repeated.
