The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] In this embodiment, the first lifting mechanism 20 is used to drive the pressing frame 30 up and down. When the pressing frame 30 descends, it presses the sleeve and body fabric. The transverse movement mechanism 40 is used to drive the second lifting mechanism 60 to move back and forth. The second lifting mechanism 60 is used to drive the ultrasonic welding mechanism 90 up and down. When the ultrasonic welding mechanism 90 descends, the welding roller 91 of the ultrasonic welding mechanism 90 abuts against the fabric. The output shaft of the motor 100 is in transmission connection with the central shaft 92, thereby driving the welding roller 91 to rotate synchronously during welding to prevent holes in the fabric and poor welds during welding. In addition, the synchronous rotation of the welding roller 91 makes the pattern less susceptible to wear, thereby extending the service life.

[0038] exist Figure 2 In the embodiment, if the ultrasonic welding mechanism 90 moves to the left, the welding roller 91 rotates synchronously counterclockwise, and the translation speed of the welding roller 91 is adapted to the rotation speed.

[0039] In this embodiment, the transverse movement mechanism 40 may adopt a linear module, the slider of the linear module faces downward, and the connecting plate 50 is connected to the slider of the linear module by screws.

[0040] Example 2:

[0041] In this embodiment, see Figure 2The pressing frame 30 includes an extension frame 31, a pressing rod 32 and a connecting rod 33. There are two extension frames 31. The lower sides of the two extension frames 31 are fixedly installed with the pressing rod 32 below the welding roller 91, and the upper sides of the two extension frames 31 are fixedly installed with the connecting rod 33.

[0042] In this embodiment, the extension frame 31 is L-shaped or triangular, which facilitates avoiding the support 80 .

[0043] Furthermore, two pressing rods 32 are provided, with a gap 321 provided between the two pressing rods 32. The gap 321 is located directly below the welding roller 91. The two pressing rods 32 compress the fabric, and the welding roller 91 welds the fabric through the gap 321 between the two pressing rods 32, further preventing fabric holes and cold welds during welding, and achieving a better welding effect.

The first lugs 11 and the extension frame 31 are slidably connected via the linear guide 21 and the slider 22. The second lug 12 is connected to the connecting rod 33 via the first push rod assembly 23. This structure drives the compression frame 30 to reciprocate longitudinally when the first push rod assembly 23 is extended or retracted.

[0046] In this embodiment, the first push rod device 23 can be a pneumatic cylinder, an electric push rod, or an electric cylinder.

[0047] Example 4:

[0048] In this embodiment, see Figure 3 The second lifting mechanism 60 includes a guide structure and a second push rod device 63. The guide structure is used to guide the lifting plate 70. The second push rod device 63 is installed on the connecting plate 50. The telescopic end of the second push rod device 63 is connected to the lifting plate 70. Through the above structure, when the second push rod device 63 is extended or retracted, it drives the lifting plate 70 to reciprocate longitudinally, thereby driving the ultrasonic welding mechanism 90 to move up and down.

[0049] In this embodiment, the guide structure includes multiple guide sleeves 61 and multiple guide shafts 62. One end of each guide sleeve 61 and guide shaft 62 is respectively connected and fixed to the connecting plate 50 and the lifting plate 70, and the other end of each guide shaft 62 and guide sleeve 61 is respectively plugged into correspondingly, and the guide shaft 62 and guide sleeve 61 slide together to guide.

[0050] In this embodiment, the second push rod device 63 can be a pneumatic cylinder or an electric push rod or an electric cylinder.

[0051] Further, referring to Figure 3 , the telescopic end of the second push rod device 63 is provided with a floating joint 64, and the floating joint 64 is connected with the lifting plate 70. The floating joint 64 is a prior art, and one end of the floating joint 64 is provided with an internal thread for threaded connection with the telescopic end of the second push rod device 63, and the other end is provided with a screw rod.

The body of the floating joint is elastic rubber, which has a buffering effect. When the second push rod device 63 is too long, the body of the floating joint is extruded and shrunk.

[0052] When the height of the second push rod device 63 is high, the second push rod device 63 is stretched out to support the plate 10, and the plate 10 is provided with a channel 13 for avoiding the second push rod device 63.

[0053] Embodiment 5:

[0054] In this embodiment, the passive wheel 94 is installed on the center shaft 92, and the driving wheel is installed on the output shaft of the motor 100.

[0055] When the passive wheel 94 and the driving wheel are gears respectively, the passive wheel 94 and the driving wheel are engaged for transmission;

[0056] When the passive wheel 94 and the driving wheel are pulleys respectively, the passive wheel 94 and the driving wheel are transmitted through a belt;

[0057] When the passive wheel 94 and the driving wheel are sprockets respectively, the passive wheel 94 and the driving wheel are transmitted through a chain.

[0058] Specifically, in this embodiment, referring to Figure 2 , 3 The support 80 is a double-ear support of a door frame structure, the two ends of the center shaft 92 of the welded roller 91 are rotatably connected with the support 80 through bearings respectively, the passive wheel 94 is installed on the center shaft 92 on the side away from the horizontal moving mechanism 40, and the end of the center shaft 92 on this side is provided with an internal thread hole, and the ultrasonic transducer 93 is screwed and fixed with the internal thread hole. Since the tail end of the ultrasonic transducer 93 is provided with an electric slip ring, the cable will not be wound when the welded roller 91 rotates.

[0059] In order to facilitate the transmission connection between the passive wheel 94 and the driving wheel, the lifting plate 70 and the support 80 are provided with holes penetrating the positions corresponding to the passive wheel 94 and the driving wheel.

[0060] The working principle or action process of the utility model is as follows:

[0061] In use, referring to Figure 2After the sleeve and body fabrics are delivered to the designated workbench, the first lifting mechanism 20 drives the pressing frame 30 downward, pressing the sleeve and body fabrics. The second lifting mechanism 60 drives the ultrasonic welding mechanism 90 downward. The welding roller 91 of the ultrasonic welding mechanism 90 passes through the gap 321 and rests on the fabric. The transverse movement mechanism 40 drives the second lifting mechanism 60 to the left, while the motor 100 simultaneously rotates the welding roller 91 counterclockwise. This prevents fabric tears and cold welds during welding. Because the welding roller 91 rotates synchronously, the pattern is less susceptible to wear, extending its service life.
