Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic fusion, and in particular to an ultrasonic fusion device. Background Technology

[0002] Ultrasonic fusion converts 50 or 60 Hz current into 15, 20, 30, or 40 kHz electrical energy using an ultrasonic generator. This high-frequency electrical energy is then converted into mechanical motion of the same frequency by a transducer. This mechanical motion is then transmitted to the welding head via an amplitude converter. The welding head transfers the received vibrational energy to the joint of the workpieces to be welded. In this region, the vibrational energy is converted into heat energy through friction. This method can be used not only to weld hard thermoplastics but also to process fabrics and films.

[0003] Waterproof clothing requires high waterproof performance and must be made of specific waterproof fabrics and leathers. At the junction of two pieces of material, ultrasonic fusion is typically used to achieve the connection. Current ultrasonic fusion equipment usually uses an ultrasonic generator to produce vibrations, with a pressure roller on top for pressure and a support plate on the bottom for support, fusing the two pieces of material together. The surface of the pressure roller typically has raised textures. During the fusion process, the pressure roller rolls over the material surface, creating a texture at the fusion joint that matches these raised textures; the texture at the fusion joint is directly determined by the outer surface of the pressure roller.

[0004] If the texture style at the fusion point needs to be changed, the upper pressure roller needs to be disassembled and replaced, which is a relatively complicated and difficult operation.

[0005] Therefore, this utility model provides a new technical solution to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an ultrasonic fusion device that can select different extrusion patterns for fusion according to fusion requirements and material properties, thereby improving replacement efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The drive roller is adjustablely mounted on the upper end of the frame and located below the ultrasonic welding assembly. The drive roller can be driven to rotate by a driver.

[0010] The ultrasonic welding assembly includes a vibrating element, and a pressure roller is rolled at the lower end of the vibrating element. The pressure roller can press against the outer periphery of the transmission roller.

[0011] The present invention is further configured such that a connecting seat is fixedly installed on the upper end of the frame and directly below the pressure roller, a movable part is slidably installed on the upper end of the connecting seat, and a telescopic rod is fixedly connected to the movable part.

[0012] The present invention is further configured such that a support platform is fixedly installed on the upper end of the frame, and a clearance groove is provided on the upper end of the support platform at a position matching the movable part. The movable part can be embedded in the clearance groove and can slide and adjust laterally along the clearance groove. The upper end surface of the movable part and the upper end of the support platform are located on the same plane.

[0013] The present invention is further configured such that the transmission roller is positioned directly below the pressure roller and is rotatably mounted on the movable part along the axis of the pressure roller, and the outer periphery of the transmission roller protrudes from the upper end surface of the movable part and can abut against the pressure roller.

[0014] The present invention is further configured such that the outer periphery of the transmission roller is provided with a plurality of annular grooves, the annular grooves being able to divide the outer periphery of the transmission roller into a plurality of transmission zones, each transmission zone being able to abut against the pressure roller through a sliding adjustment movable part.

The transmission roller and the pressure roller are arranged axially parallel to each other. The pressure roller can slide and abut against the outer circumference of the transmission roller in the vertical direction, so that the material joint is placed between the transmission roller and the pressure roller to complete ultrasonic fusion. The outer circumference of the transmission roller is divided into several transmission zones by an annular groove.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This embodiment discloses an ultrasonic fusion device, referring to... Figures 1-6As shown, the assembly mainly includes a frame 1, an ultrasonic welding component 2, and a drive roller 3. A support frame 12 is fixedly installed on the upper end of the frame 1, and the ultrasonic welding component 2 is vertically adjustable and installed on the support frame 12. The ultrasonic welding component 2 mainly includes an ultrasonic generator 22, a vibrating element 23 is fixedly installed on the lower end of the ultrasonic generator 22, and a pressure roller 24 is rolled on the lower end of the vibrating element 23. A drive roller 3 is adjustablely installed on the upper end of the frame 1 and directly below the ultrasonic welding component 2. The drive roller 3 can rotate, and its axis is parallel to the pressure roller 24. By adjusting the ultrasonic welding component 2 vertically, the pressure roller 24 and the outer periphery of the drive roller 3 can be brought into contact and driven. The material to be ultrasonically fused passes between the pressure roller 24 and the drive roller 3, achieving ultrasonic bonding.

[0029] Reference Figure 3 and Figure 4 As shown, a connecting seat 31 is fixedly installed at the upper end of the frame 1 and directly below the pressure roller 24. A movable part 32 is slidably installed on the upper end of the connecting seat. The movable part 32 is arranged laterally along the axis of the pressure roller 24 and is fixedly connected to the telescopic actuator 34 via a telescopic rod 33. The telescopic actuator 34 is fixedly installed on the frame 1. Under the driving action of the telescopic actuator 34, the telescopic rod 33 extends and retracts, driving the movable part 32 to move laterally. The transmission roller 3 is located directly below the pressure roller 24 and is rotatably installed on the movable part 32 along the axis of the pressure roller 24. The outer periphery of the transmission roller 3 protrudes from the upper end face 321 of the movable part 32. It can transmit the material at the upper end of the transmission roller 3 and also support the material, facilitating the pressure roller 24 to press the material for ultrasonic fusion. The transmission roller 3 can rotate axially relative to the movable part 32 and can also move synchronously with the movable part 32 under the driving action of the telescopic actuator 34.

[0030] Reference Figure 5 and Figure 6 As shown, several annular grooves 35 are formed on the outer periphery of the transmission roller 3, dividing the outer periphery of the transmission roller 3 into several transmission zones 36, each of which is spaced apart along the axial direction. By adjusting the movable part 32, the positional relationship between different transmission zones 36 and the upper pressure roller 24 can be adjusted. When the transmission zone 36 is adjusted to be directly below the pressure roller 24, the two can achieve upper and lower pressing.

[0031] The axial dimension of the transmission zone 36 is larger than that of the pressure roller 24. Different textures are provided in each transmission zone 36. The appropriate texture can be selected according to the material fusion requirements or the material material. Under the pressure of the pressure roller 24, ultrasonic fusion is carried out, which can effectively improve the connection strength between materials after fusion and improve the fusion quality.

[0032] Reference Figure 2 As shown, the ultrasonic welding assembly 2 also includes a connector 21, which is fixedly installed on the upper end of the ultrasonic generator 22. A fixed seat 13 is fixedly installed on one end of the support frame 12 facing the connector 21. Guide rails 14 are fixedly installed on both sides of the fixed seat 13 in the vertical direction. The ultrasonic generator 22 is slidably connected to the guide rails 14 on both sides through the connector 21 and driven by the telescopic driver 15, so that the ultrasonic generator 22 can slide and adjust in the vertical direction. This allows the pressure roller 24, which is rolled at the end of the vibrating element 23, to bring the material abutting against the outer periphery of the transmission roller 3. Under the action of the ultrasonic generator, the material is welded and fused.

[0033] Reference Figure 1 and Figure 2 As shown, a support platform 11 is fixedly installed on the upper end of the frame 1. A relief groove 111 is provided on the upper end of the support platform 11 at the position that matches the movable part 32. The movable part 32 can be embedded in the relief groove 11 and can slide and adjust laterally along the relief groove 111. The upper end surface 321 of the movable part 32 is on the same plane as the upper end of the support platform 11, and can be used to support the material so that it can be laid horizontally on the upper end of the transmission roller 3. The material is pressed against the upper end of the transmission roller 3 by the pressure roller 24 for fusion.
