Description

Technical Field

[0001] This application relates to the field of polyester fabric production technology, specifically to a frequency-tunable ultrasonic connector machine for polyester fabric production. Background Technology

[0002] In the production and processing of polyester fabric, it is often necessary to splice or join two or more pieces of fabric. Traditional sewing or heat-pressing methods suffer from low efficiency, increased thickness at the joint, uneven strength, and unsightly appearance. With the development of ultrasonic welding technology, its application in the textile industry is gradually increasing, enabling threadless, fast, and strong joints.

[0003] Chinese patent discloses an ultrasonic joint for polyester fabric production (publication number CN222097041U). This patented technology includes a machine base, a power supply box mounted on one outer wall of the base, an internal cavity containing an electric push rod, and an ultrasonic control box mounted on the rear end of the base. It also includes a support base fixed to the upper part of the machine base with screws, a transducer mounted on the upper end of the support base, an amplitude transformer mounted on the lower end of the transducer, and a welding head mounted on the lower end of the amplitude transformer; a movable platform positioned directly below the welding head, with a welding head groove inside the movable platform, and electromagnet plates on both sides of the groove. This technology solves the problem of existing fabric splicing machines using roller mechanisms to assist continuous fabric splicing, where the roller structure only assists fabric movement, leading to poor splice stability when the fabric is long.

[0004] However, it cannot achieve continuous conveying and welding, nor can it trim the edges. Furthermore, existing ultrasonic jointing equipment often has limited functionality in feeding, pressing, and cutting processes, failing to achieve continuous and automated integrated welding and cutting operations. It also has limitations in welding frequency adjustment, fabric edge positioning, and cutting accuracy control, affecting production efficiency and joint quality. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A frequency-adjustable ultrasonic joint machine for polyester fabric production includes a base and a frequency-adjustable control box fixed to the upper rear side of the base.

[0021] Please see Figures 1-5In this embodiment of the invention, a frequency-adjustable ultrasonic joint machine for polyester fabric production includes a base 1 and a frequency-adjustable control box 2 fixed to the upper rear side of the base 1. An electric cylinder 9 is embedded in the upper end of the base 1. The output end of the electric cylinder 9 is located in front of the frequency-adjustable control box 2 and connected to a lifting frame 4. An amplitude transformer 11 is installed through the inner side of the lifting frame 4. A transducer 10 is installed at the upper end of the amplitude transformer 11, and a welding head 7 is installed at the lower end of the amplitude transformer 11. A welding and cutting mechanism 5 is installed on one side of the welding head 7. On the other side, a motor 13 is connected via a feeding roller bracket 12. An active feeding roller 14 is installed at the output end of the motor 13. A welding seat 8 is embedded in the upper end of the base 1 near the welding and cutting mechanism 5 and the lower end of the active feeding roller 14. A set of slide rails 3 is fixedly connected to the front end of the frequency modulation control box 2, and a set of sliding grooves is opened at the rear end of the lifting frame 4 on the outside of the slide rails 3. When the electric cylinder 9 drives the lifting frame 4 to move up and down, the sliding grooves on the lifting frame 4 slide along the slide rails 3, thereby ensuring that the lifting frame 4 moves up and down smoothly.

[0022] exist Figure 1 and Figure 2 In the process, a driven pressure roller 6 is embedded in the lower end of the welding base 8 near the welding and cutting mechanism 5, and a driven feeding roller 15 is embedded in the lower end of the welding base 8 near the active feeding roller 14. The welding edges of the two polyester fabrics to be welded are overlapped and placed on the driven feeding roller 15. When the electric cylinder 9 drives the lifting frame 4, the amplitude rod 11 and the welding head 7 to descend together, the feeding roller bracket 12, the motor 13 and the active feeding roller 14 also descend together. The active feeding roller 14 and the driven feeding roller 15 press the two polyester fabrics down. Then, the motor 13 drives the active feeding roller 14 to rotate, so that the two polyester fabrics can be conveyed to the bottom of the welding head 7 to achieve automatic continuous welding.

[0023] exist Figure 3 and Figure 4 In the welding and cutting mechanism 5, a pressure roller bracket 55 is fixed to the outside of the welding head 7. A motor 52 is fixedly connected to the lower side of one end of the pressure roller bracket 55. An active pressure roller 51 is fixedly connected to the output end of the motor 52. The active pressure roller 51 corresponds to the driven pressure roller 6. When the electric cylinder 9 drives the welding head 7 to move down and welds two pieces of polyester fabric through the welding head 7, the welded polyester fabric enters between the driven pressure roller 6 and the active pressure roller 51. The active pressure roller 51 is rotated by the motor 52, and the weld joint is continuously squeezed by the driven pressure roller 6 and the active pressure roller 51, so that the joint is firmly and reliably bonded.

[0024] exist Figure 3 , Figure 4 and Figure 5In the middle, a connecting frame 53 is fixedly connected to the upper front side of the pressure roller bracket 55. A cylinder 54 is fixedly connected to the connecting frame 53. A cylinder 56 is fixedly connected to the output end of the cylinder 54. A connecting frame 57 is fixedly connected to the output end of the cylinder 56. A motor 58 is fixedly connected to the lower end of the connecting frame 57. A cutting disc 59 is fixedly connected to the output end of the motor 58. When two pieces of polyester fabric are fused together, and it is necessary to cut off the excess edges, firstly, the cylinder 54 drives the cylinder 56, the connecting frame 57, the motor 58, and the cutting disc 59 to move back and forth together, adjusting the position of the cutting disc 59 in the back and forth direction, thereby adjusting the cutting width of the polyester fabric; then, the cylinder 56 drives the connecting frame 57, the motor 58, and the cutting disc 59 to move up and down, so that the cutting disc 59 reaches the polyester fabric; then, the motor 58 drives the cutting disc 59 to rotate, and the cutting disc 59 cuts off the excess edges of the polyester fabric.

[0025] A set of guide sleeves 511 are fixedly connected to both ends of the outer side of cylinder 54. A guide rod 510 is slidably connected through the inner side of each guide sleeve 511. The front end of the guide rod 510 is fixedly connected to cylinder 56. Therefore, when the output end of cylinder 54 drives cylinder 56 to move, the guide rod 510 slides along the inner side of the guide sleeve 511, thereby ensuring the stability of the movement of cylinder 56.

[0026] A set of guide sleeves 513 are fixedly connected to both ends of the outer side of cylinder 2 56. A guide rod 512 is slidably connected through the inner side of each guide sleeve 513. The lower end of the guide rod 512 is fixedly connected to the connecting frame 2 57. Therefore, when the output end of cylinder 2 56 drives the connecting frame 2 57 to move, the guide rod 512 slides along the inner side of the guide sleeve 513, thereby ensuring the stability of the movement of the connecting frame 2 57.

[0027] Working principle: When two pieces of polyester fabric need to be welded together, firstly, the welding edges of the two pieces of polyester fabric to be welded are overlapped and placed on the driven feeding roller 15; when the electric cylinder 9 drives the lifting frame 4, the amplitude rod 11 and the welding head 7 to descend together, the feeding roller support 12, the motor 13 and the active feeding roller 14 also descend together; the active feeding roller 14 and the driven feeding roller 15 press the two pieces of polyester fabric down; then the motor 13 drives the active feeding roller 14 to rotate, conveying the two pieces of polyester fabric downwards from the welding head 7;

[0028] When the two pieces of polyester fabric move the bottom of the welding head 7 at the same time, the resonant frequency of the transducer 10 is first adjusted by the frequency control box 2. The frequency range is 15kHz-40kHz. The power supply frequency is then adjusted by the transducer 10 to convert high-frequency electrical energy into mechanical vibration. The amplitude of the transducer 10 is amplified by the amplitude transformer 11 and transmitted to the welding head 7. The welding head 7 then welds the joint of the two pieces of polyester fabric together.

[0029] After the welding is completed, the polyester fabric is fed between the active pressure roller 51 and the driven pressure roller 6. The motor 52 is started and drives the active pressure roller 51 to rotate. The driven pressure roller 6 and the active pressure roller 51 continuously squeeze the weld joint, making the joint firmly and reliably bonded.

[0030] When it is necessary to trim excess edges, cylinder 54 drives cylinder 56, connecting frame 57, motor 58 and cutting disc 59 to move back and forth; adjust the cutting width of polyester fabric; then cylinder 56 drives connecting frame 57, motor 58 and cutting disc 59 to move up and down, so that cutting disc 59 reaches the polyester fabric, and then motor 58 drives cutting disc 59 to rotate, and cutting disc 59 trims excess edges of polyester fabric.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
