[0025] Please see Figures 1 to 4 The present invention provides an embodiment of a seamless underwear piece bonding device, which includes an ultrasonic seamless underwear machine 1 and a disassembly / assembly component 2, the disassembly / assembly component 2 being disposed inside the ultrasonic seamless underwear machine 1.

[0026] The assembly / disassembly component 2 includes an installation groove 21, a fixing post 22, a fixing tube 23, a connecting plate 24, and an elastic band 25. The fixing post 22 is fixed on one side of the installation groove 21. The fixing posts 22 are evenly distributed along the width of the installation groove 21, and there are three sets of fixing posts 22. The fixing tube 23 is sleeved on the outside of any set of fixing posts 22. The connecting plate 24 is fixed on the outer surface of the fixing tube 23, and the elastic band 25 is sleeved on the outside of the fixing tube 23.

[0027] The mounting slot 21 provides a spatial layout framework, the fixing column 22 forms a stable support node, and provides a positioning reference for the fixing tube 23. The fixing tube 23 is detachably sleeved on the outside of the fixing column 22, carries the elastic band 25 and enables its quick replacement. The connecting plate 24 is fixed to the outer surface of the fixing tube 23 and transmits the operating torque to drive subsequent actions. The elastic band 25 is a key elastic element, which works with the pressure roller 14 to clamp the fabric and ensure uniform pressure during ultrasonic bonding.

[0028] A fixing frame 26 is fixed to the surface of the connecting plate 24 away from the fixing post 22. The fixing frames 26 are arranged opposite to each other. A rotating post 27 is rotatably connected inside the fixing frame 26.

[0029] The fixed frame 26 limits the movement trajectory of the rotating column 27 to ensure the stability of the flipping action. The rotating column 27 unlocks or locks the connecting plate 24 by flipping, forming a core transmission mechanism for quick assembly and disassembly.

[0030] A limiting plate 28 is fixed on the side of the mounting groove away from the fixed column 22, and the surface of the limiting plate 28 is in contact with the surfaces of both ends of the rotating column 27.

[0031] The limiting plate 28 restricts the axial displacement of the rotating column 27 and together with the screw 29 forms an anti-disengagement locking structure;

[0032] Screws 29 are threadedly connected to the internal parts of the limiting plate 28 and the rotating column 27.

[0033] Screw 29 passes through the limiting plate 28 and the rotating column 27, and achieves double-safety fastening through the thread;

[0034] An inclined plate 291 is fixed on the side of the mounting slot 21 near the fixed column 22. The inclined plate 291 gradually increases in height from the rotating column 27 toward the fixed column 22.

[0035] The inclined plate 291 can easily guide fallen debris out of the mounting slot 21;

[0036] The ultrasonic seamless underwear machine 1 includes a support platform 11 and a machine head 12. The mounting groove 21 is opened inside the support platform 11, and the machine head 12 is fixed to the top of the support platform 11.

[0037] The support platform 11 is the basic platform of the equipment, used to support and fix the built-in disassembly and assembly parts 2, and to provide a processing plane for the underwear cutting pieces. The machine head 12 is the power and execution core of the equipment, which contains an ultrasonic generator, transducer, etc., to convert electrical energy into high-frequency mechanical vibration.

[0038] The bottom of the machine head 12 is provided with a mounting base 13, and a pressure roller 14 is installed inside the mounting base 13. The pressure roller 14 is located on the top of the elastic band 25. The bottom of the machine head 12 is provided with a knife holder 15, and a knife 16 is installed and fixed at the bottom of the knife holder 15.

[0039] Mounting base 13 is used to fix pressure roller 14, which is the output end of ultrasonic energy. It applies high-frequency vibration and pressure to the underwear fabric piece and cooperates with elastic band 25 below to complete bonding and pressing. Blade holder 15 is used to install and fix blade 16 in the required position. Blade 16 is used to perform precise cutting while bonding, realizing integrated bonding and cutting operation and improving production efficiency.

[0040] Working principle: When it is necessary to process the underwear, first align the underwear and place it in place. Then place the underwear on the top of the support platform 11 and adjust and move the support platform 11 to the bottom of the pressure roller 14 to apply a pushing force to the underwear, so that the underwear moves between the pressure roller 14 and the elastic band 25. Ultrasonic waves are used to achieve adhesion of the underwear. During this process, the cutter 16 will move back and forth to cut the underwear.

[0041] When the elastic band 25 needs to be replaced, apply a rotational force to the screw 29 to remove it from inside the limiting plate 28. Then, apply a flipping force to the rotating column 27 to make it flip towards the connecting plate 24. Next, apply a pulling force to the connecting plate 24 to remove the fixing tube 23 from the outside of the fixing column 22. Pull the old elastic band 25 off the outside of the fixing tube 23 and put the new elastic band 25 on the outside of the fixing tube 23. Then, insert the fixing tube 23 into the outside of the fixing column 22. Apply a rotational force to the rotating column 27 so that it is inserted between the two sets of limiting plates 28. Finally, put the screw 29 into the limiting plate 28 and apply a rotational force to the screw 29.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
