Description

Technical Field

[0001] The utility model relates to the technical field of ultrasound, in particular to a vertically vibrating ultrasonic transverse sealing welder and a transverse sealing welding structure. Background Art

[0002] Ultrasonic welding utilizes a generator to generate a high-voltage, high-frequency signal. This signal is converted into high-frequency mechanical vibrations through a transducer system. This vibration is then applied to the plastic workpiece. Friction between the workpiece surface and internal molecules causes the temperature of the weld to rise. When the temperature reaches the melting point of the workpiece itself, the workpiece interface rapidly melts, filling the gap between the interfaces. When the vibration stops, the workpiece cools and sets under a certain pressure, completing the weld.

[0003] In the prior art, ultrasonic transverse sealing welding is completed by moving the welding surface of an ultrasonic welding head relative to a welding base to complete ultrasonic welding, or by moving the welding surfaces of two ultrasonic welding heads relative to each other to complete ultrasonic welding. This working process is too cumbersome and inefficient, and cannot meet the application requirements of the production market. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. 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.

[0026] Reference Figure 1-3 The figure shows a preferred embodiment of the present invention.

[0027] The vertical vibration ultrasonic transverse seal welder includes a plate-shaped welding head 10, with welding surfaces 20 formed on the front and rear sides of the welding head 10, and connecting structures 60 for connecting ultrasonic vibrators formed at both ends of the welding head 10. The welding head 10 is provided with a plurality of hollow areas 40, which are arranged in strips extending between the two welding surfaces 20.

[0028] When the ultrasonic vibrator drives the welding head 10 to vibrate, the welding surface 20 is vibrated up and down.

[0029] The above-mentioned up-and-down vibration ultrasonic transverse sealing welder, the welding head 10 can reduce the overall weight of the welding head 10 and reduce the air resistance during the rotation welding process of the welding head 10 through multiple hollow areas 40, thereby improving the working efficiency of the ultrasonic transverse sealing welding, and improving the stability of the welding head 10 during the up-and-down vibration process, making the ultrasonic transverse sealing welding process simple, and solving the problem that the working process of the ultrasonic transverse sealing welding is too complicated and the working efficiency is low.

[0030] In this embodiment, multiple hollow areas 40 are sequentially spaced apart in the welding head 10 along the length of the welding surface 20. This can reduce the overall weight of the welding head 10, reduce air resistance during the welding process of the welding head 10 during rotation, and increase the stability of the welding head 10 during the up and down vibration process.

[0031] In this embodiment, the front and rear sides of the welding head 10 respectively have convex side portions 30, and the outer ends of the side portions 30 are formed with flat welding surfaces 20. In this way, the welding head 10 can be prevented from interfering with the material during rotation.

[0032] In this embodiment, along the direction in which the side portion 30 bulges outward, the upper and lower sides of the side portion 30 gradually converge inward. In this way, the welding head 10 designed in this way has the characteristics of overall structural stability and uniform force at all positions when the welding surface 20 is pressed down.

[0033] In this embodiment, the hollow area 40 extends from top to bottom through the welding head 10 and the two side portions 30. This can reduce the overall weight of the welding head 10, reduce air resistance during the welding process of the welding head 10, and increase the stability of the welding head 10 during the up and down vibration process.

[0034] The multiple hollow areas 40 are two first hollow grooves 41 and two second hollow grooves 42. The length of the first hollow groove 41 is greater than that of the second hollow groove 42. The two second hollow grooves 42 are arranged adjacent to each other, and the two first hollow grooves 41 are respectively located on the left and right sides of the two second hollow grooves 42.

[0035] In this embodiment, the side portion 30 has outer end surfaces 11 at both ends, with a welding surface 20 connecting the two outer end surfaces 11. The outer end surfaces 11 are recessed inward to form a groove 12, which extends vertically through the side portion 30. This enhances structural stability and makes the side portion 30 more stable when subjected to stress.

[0036] The groove 12 has an inner wall surface 13 , and both sides of the inner wall surface 13 are arc-shaped curved surfaces.

[0037] In this embodiment, transition sections 50 are provided on both ends of the welding head 10, projecting outward. The transition sections 50 and the welding head 10 are integrated into one structure, and the connecting structure 60 is located within one of the transition sections 50. This allows the ultrasonic transducer to be connected to the connecting structure 60, and the connecting structure 60 and the welding head 10 to achieve structural strength through the transition sections 50, while also improving heat dissipation performance.

[0038] The utility model also provides a transverse sealing welding structure, comprising the above-mentioned upper and lower vibration ultrasonic transverse sealing welder, comprising two upper and lower vibration ultrasonic transverse sealing welders, the two welders being arranged in a rotational manner;

[0039] When the welding surfaces 20 of the two welders are arranged facing each other, a welding gap is formed for the material to pass through. When the welding surfaces 20 of the welding heads 10 rotate and separate, the material passes through the welding gap.

[0040] Compared with the prior art, the transverse sealing welding structure provided by the present invention can improve the welding efficiency of continuous transverse sealing welding and optimize the overall structure of transverse sealing welding, thereby reducing welding costs.

[0041] 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.
