Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to a non-woven fabric ultrasonic welding device. Background Art

[0002] Non-woven fabric is a kind of non-woven fabric. It is a new type of fiber product with soft, breathable and planar structure formed directly from polymer chips, short fibers or filaments through various fiber web forming methods and consolidation technologies. In the process of non-woven fabric processing, ultrasonic welding equipment is needed to weld non-woven fabric.

[0003] For example, the utility model with application number CN202122078465.7 discloses an integrated ultrasonic welding and trimming device for non-woven fabrics. The utility model has a reasonable structure, and the provided integrated ultrasonic welding and trimming device for non-woven fabrics combines the two processes of ultrasonic welding and trimming into one integrated process, simplifying the process path. However, in the actual use of such devices, when the width of the non-woven fabric is greater than the width of the upper mold welding head, it is usually necessary to adjust the position of the non-woven fabric and perform two weldings to weld one side of the non-woven fabric. In the process of manually adjusting the position and aligning the non-woven fabric, it is relatively time-consuming, resulting in the problem of affecting the welding efficiency of the non-woven fabric.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a non-woven fabric ultrasonic welding device is provided. Utility Model Content

[0007] Furthermore, the positioning block is slidably connected to the loading plate, and one side of the positioning block is in an arc shape.

[0008] Furthermore, the positioning assembly includes a spring seat and a connecting ear. The spring seats are arranged on both sides of the loading plate, and the connecting ear is fixed on the top of the spring seat.

[0009] Furthermore, the positioning assembly also includes a pressing frame and a rubber pad. The pressing frame is arranged between the connecting ears, and the rubber pad is arranged at the bottom of the pressing frame.

[0010] Furthermore, the positioning assembly also includes side plates and a damping shaft. The two sides of the pressure frame are slidably connected to the side plates, and the upper ends of the side plates are rotatably connected to the damping shaft.

[0014] The utility model provides a non-woven fabric ultrasonic welding device, which has the following beneficial effects:

[0015] 1. The utility model sets a moving component. When one side of the non-woven fabric is too long and needs to be welded twice, after welding once, it is only necessary to loosen the bolt to drive the positioning block to separate from the guide rod, so as to facilitate the left and right movement of the carrier plate. At the same time, since the positioning component fixes the non-woven fabric on the carrier plate, the position of the non-woven fabric can be quickly adjusted when the carrier plate is moved, reducing the calibration time, thereby improving the efficiency of ultrasonic welding of the non-woven fabric. When positioning, it is only necessary to tighten the bolt and increase the friction between the positioning block and the guide rod through the anti-slip pad, thereby enhancing the stability after adjustment.

[0016] 2. The utility model is provided with a positioning component. When the handle is pushed upward, the cam will be driven to rotate through the damping shaft. At this time, the spring seat will push the connecting ear and drive the pressure frame to move upward, so as to facilitate the placement of the non-woven fabric between the pressure frame and the loading plate. After alignment, it is only necessary to press the handle downward to drive the cam to rotate through the damping shaft. The cam will squeeze the pressure frame and the non-woven fabric can be quickly pressed and positioned, thereby improving the convenience of positioning. The provision of multiple cams can make the force application more uniform, and cooperate with the rubber pad to prevent the non-woven fabric from slipping after positioning.

When the carrier plate 802 is moved, the position of the non-woven fabric can be quickly adjusted to reduce the calibration time, thereby improving the efficiency of ultrasonic welding of the non-woven fabric. One end of the bolt 803 is rotatably connected with a positioning block 804, and an anti-skid pad 805 is provided on one side of the positioning block 804. It only needs to tighten the bolt 803 and increase the friction between the positioning block 804 and the guide rod 801 through the anti-skid pad 805, thereby enhancing the stability after adjustment. The positioning block 804 is slidably connected to the carrier plate 802, and one side of the positioning block 804 is in an arc shape. Loosening the bolt 803 can drive the positioning block 804 to separate from the guide rod 801, thereby facilitating the adjustment of the position of the carrier plate 802.

[0023] like Figure 3As shown, a positioning component 9 is provided on the top of the carrier plate 802, and the positioning component 9 includes a spring seat 901 and a connecting ear 902. Spring seats 901 are provided on both sides of the carrier plate 802, and the connecting ear 902 is fixed on the top of the spring seat 901. When taking and placing the non-woven fabric, the spring seat 901 will push the connecting ear 902, driving the pressing frame 903 to move up, so as to facilitate the placement of the non-woven fabric between the pressing frame 903 and the carrier plate 802. The positioning component 9 also includes a pressing frame 903 and a rubber pad 904. The pressing frame 903 is arranged between the connecting ears 902, and the rubber pad 904 is provided at the bottom of the pressing frame 903.

After alignment, press the handle 907 downward to drive the cam 908 to rotate through the damping shaft 906, and the cam 908 will squeeze the pressing frame 903, so that the non-woven fabric can be quickly pressed and positioned, and the friction force during positioning is increased with the rubber pad 904. Next, start the electric cylinder 4 to drive the ultrasonic welding machine body 5 (the same welding principle as the ultrasonic welding machine of model 5000IQ) to move downward , so that the welding head 7 and the lower mold 2 press the non-woven fabric, and at the same time, the ultrasonic generator and ultrasonic transducer inside the ultrasonic welding machine body 5 transmit the vibration to the welding head 7 through the amplitude rod 6, so as to weld the non-woven fabric. Then, when it is necessary to adjust the position, loosen the bolt 803, which can drive the positioning block 804 to separate from the guide rod 801, so that the position of the non-woven fabric can be quickly adjusted when the carrier plate 802 is moved. Finally, after adjusting the position, it is only necessary to tighten the bolt 803 and increase the friction between the positioning block 804 and the guide rod 801 through the anti-slip pad 805, so as to enhance the stability after adjustment, so as to ultrasonically weld the non-woven fabric again.
