Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0023] Reference Figure 1-3 The figure shows a preferred embodiment of the present invention.

[0024] The ultrasonic transverse seal welding structure includes a first welder 10 and a second welder 20 that are arranged in a movable manner. The first welder 10 includes a welding head 11, which is connected to a horn 14. The horn 14 is connected to an ultrasonic vibrator 12. The ultrasonic vibrator 12 drives the welding head 11 to vibrate through the horn 14. The welding head 11 and the second welder 20 are arranged opposite each other, and a welding gap 13 is formed between the welding head 11 and the second welder 20.

[0025] When the material to be horizontally sealed passes through the welding gap 13, the first welder 10 moves toward the second welder 20, clamping and contacting the material, and horizontally sealing the material through vibration.

[0026] In the ultrasonic transverse sealing welding structure provided above, the first welder 10 moves relative to the second welder 20 to perform abutment welding on the material passing through the welding gap 13. The first welder 10 vibrates at a high frequency through the ultrasonic vibrator 12, thereby driving the welding head 11 to perform abutment welding on the material, which can increase the temperature at the sealing point to reach the sealing temperature. This not only improves the transverse sealing efficiency, but also simplifies the operation, meets the requirements of automated production, and solves the problem of low efficiency in the packaging of the transverse sealing structure.

[0027] In this embodiment, the second welder 20 is a fixed base.

[0028] When the material is thin, the second welder 20 can be directly a fixed base, and the one-way welding of the first welder 10 can ensure a firm welding, thereby improving welding efficiency and reducing costs.

[0029] In this embodiment, when the structure of the second welder 20 is the same as that of the first welder 10 , the first welder 10 and the second welder 20 move toward each other to clamp and vibrate weld the material, or move away from each other to facilitate the material to pass through the welding gap 13 .

[0030] When the thickness of the material is large, the structure of the second welder 20 is the same as that of the first welder 10. At this time, the first welder 10 and the second welder 20 move toward each other to clamp and vibrate weld the material, or move away from each other to facilitate the material to pass through the welding gap 13; in this way, bidirectional vibration welding can achieve better welding effects, thereby improving welding efficiency and realizing automated welding.

[0031] In this embodiment, the bottom of the horn 14 abuts against the top of the welding head 11, and the top of the horn 14 abuts against the bottom of the ultrasonic vibrator 12. The bottom of the welding head 11 forms a welding bottom surface 113, and the outer periphery of the welding head 11 forms a mounting surface 111, and a mounting structure 114 is provided on the mounting surface 111.

[0032] In the prior art, during installation, the mounting structure 114 is often mounted on the vibrator. In this way, the distance between the mounting position and the welding surface of the welding head 11 is too far, resulting in excessive shaking of the welding head 11. The mounting structure 114 is provided on the mounting surface 111 of the welding head 11, thereby reducing the distance between the welding bottom surface 113 and the mounting structure 114, thereby reducing the shaking amplitude of the welding head 11.

[0033] In this embodiment, a plurality of mounting structures 114 are provided on the mounting surface 111, and the plurality of mounting structures 114 are spaced apart along the length direction of the mounting surface 111. In this way, the stability of the welding head 11 during welding can be increased, and the shaking amplitude of the welding head 11 can be reduced.

[0034] In this embodiment, the mounting structure 114 includes a connecting section 115 connected to the mounting surface 111, the connecting section 115 has a longitudinal section 116 extending upward, the top of the longitudinal section 116 has a transverse section 117 extending outward away from the mounting surface 111, the connecting section 115, the longitudinal section 116 and the transverse section 117 are an integrated structure, so that the mounting structure 114 can be connected to the outside through the connecting section 115, the longitudinal section 116 and the transverse section 117 to reduce the shaking amplitude of the welding head 11.

[0035] In this embodiment, a mounting gap is formed between the longitudinal section 116 and the mounting surface 111, and the longitudinal section 116 is arranged perpendicular to the transverse section 117. In this way, better mounting can be achieved through the mounting gap.

[0036] A transversely arranged connecting surface 112 is formed on the top of the welding head 11 , and the ultrasonic vibrator 12 is mounted on the connecting surface 112 from top to bottom.

[0037] In this embodiment, a plurality of ultrasonic vibrators 12 are connected to the connection surface 112, and the plurality of ultrasonic vibrators 12 are sequentially spaced apart along the length direction of the connection surface 112. In this way, the stability of the welding process of the welding head 11 can be increased.

[0038] When the length of the transverse seal needs to be adjusted, multiple ultrasonic transverse seal welding structures are arranged in parallel to increase the transverse seal length. This can improve the applicable range of transverse seal welding.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
