The moving assembly (8) is disposed inside the worktable (1). In the non-woven fabric ultrasonic welding device, by means of the provision of the moving assembly (8), when a non-woven fabric has a too long side and requires welding in two stages, after a single welding operation, a positioning block (804) can be driven to separate from a guide rod (801) simply by loosening a bolt (803), thereby facilitating the left and right movement of a loading plate (802). In addition, since a positioning assembly (9) fixes the non-woven fabric onto the loading plate (802), the position of the non-woven fabric can be quickly adjusted whiling moving the loading plate (802), reducing the time for calibration.

Description

A nonwoven fabric ultrasonic welding device Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, specifically to a nonwoven fabric ultrasonic welding device. Background Technology

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

[0003] For example, utility model application CN202122078465.7 discloses an integrated ultrasonic welding and trimming device for nonwoven fabrics. This utility model has a reasonable structure, combining ultrasonic welding and trimming into a single process, simplifying the process path. However, in actual use, when the width of the nonwoven fabric is greater than the width of the upper die welding head, it is usually necessary to adjust the position of the nonwoven fabric and perform two welding operations to weld one side of the nonwoven fabric. Manually adjusting and aligning the position of the nonwoven fabric is time-consuming, thus affecting the welding efficiency of the nonwoven fabric.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a non-woven fabric ultrasonic welding device.

[0005] Utility Model Content

[0006] The purpose of this invention is to provide a nonwoven fabric ultrasonic welding device to solve the problems mentioned in the background art.

[0007] [Amended according to Rule 26, August 2024] To achieve the above objectives, this utility model provides the following technical solution: A non-woven fabric ultrasonic welding device, comprising a worktable and a moving component. A lower mold is installed at one end of the middle of the worktable, and a frame is fixed on the top of the worktable. An electric cylinder is installed on the top of the frame, and an ultrasonic welding machine body is connected to the bottom of the electric cylinder. An amplitude transformer is installed at the lower end of the ultrasonic welding machine body, and a welding head is installed at the bottom of the amplitude transformer. The moving component is located inside the worktable. The moving component includes a guide rod, a carrying plate, a bolt, a positioning block, and an anti-slip pad. The carrying plate is slidably connected to the outer side of the guide rod, and a bolt is threadedly connected to the middle of one side of the carrying plate. One end of the bolt is rotatably connected to the positioning block, and an anti-slip pad is provided on one side of the positioning block. A positioning component is provided on the top of the carrying plate.

[0008] Furthermore, the positioning block is slidably connected to the carrier plate, and one side of the positioning block is arc-shaped.

[0009] Furthermore, the positioning component includes a spring seat and a connecting ear, with spring seats provided on both sides of the carrier plate and a connecting ear fixed to the top of the spring seat.

[0010] Furthermore, the positioning component also includes a pressure frame and a rubber pad, with the pressure frame positioned between the connecting ears and the rubber pad provided at the bottom of the pressure frame.

[0011] Furthermore, the positioning component also includes side plates and a damping shaft. The side plates are slidably connected to both sides of the pressure frame, and the damping shaft is rotatably connected to the upper end of the side plates.

[0012] Furthermore, the side plate is fixedly connected to the carrier plate, and the side plate is slidably connected to the connecting lug.

[0013] Furthermore, the positioning component also includes a handle and a cam, with the handle connected to the end of the damping shaft and a cam provided on the outer side of the damping shaft.

[0014] Furthermore, the cams are equidistantly distributed about the outer side of the damping shaft, and the cams are slidably connected to the pressure frame.

[0015] This utility model provides a non-woven fabric ultrasonic welding device, which has the following beneficial effects:

[0016] 1. This utility model, through the setting of the moving component, allows the positioning block to separate from the guide rod after the first welding when one side of the non-woven fabric is too long and needs to be welded in two stages. This facilitates the left and right movement of the carrier plate. At the same time, since the positioning component fixes the non-woven fabric to the carrier plate, the position of the non-woven fabric can be quickly adjusted when moving the carrier plate, reducing the calibration time and improving the efficiency of ultrasonic welding of non-woven fabric. Furthermore, during positioning, only the bolt needs to be tightened, and the friction between the positioning block and the guide rod is increased by the anti-slip pad, thereby enhancing the stability after adjustment.

[0017] 2. This utility model, through the setting of the positioning component, will drive the cam to rotate through the damping shaft when the handle is pushed upward. At this time, the spring seat will push the connecting ear, causing the pressure frame to move upward, thus making it convenient to place the non-woven fabric between the pressure frame and the carrier plate. After alignment, simply press down the handle to drive the cam to rotate through the damping shaft. The cam will then squeeze the pressure frame, which can quickly press and position the non-woven fabric, thereby improving the convenience of positioning. The setting of multiple cams can make the force applied more even, and the rubber pad can be used to prevent the non-woven fabric from slipping after positioning. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] [Revised according to Rule 26, August 2024] As shown in Figures 1 and 2, a nonwoven fabric ultrasonic welding device includes a worktable 1 and a moving assembly 8. A lower mold 2 is installed at one end of the middle of the worktable 1, and a frame 3 is fixed on the top of the worktable 1. An electric cylinder 4 is installed on the top of the frame 3, and an ultrasonic welding machine body 5 is connected to the bottom of the electric cylinder 4. An amplitude transformer 6 is installed at the lower end of the ultrasonic welding machine body 5, and a welding head 7 is installed at the bottom of the amplitude transformer 6. The vibration is transmitted to the welding head 7 through the ultrasonic generator and ultrasonic transducer inside the ultrasonic welding machine body 5 via the amplitude transformer 6, thereby performing ultrasonic welding on the nonwoven fabric. The moving assembly 8 is located inside the worktable 1 and includes a guide rod 801, a carrying plate 802, bolts 803, positioning blocks 804, and anti-slip pads 805. 05. A carrying plate 802 is slidably connected to the outer side of the guide rod 801, and a bolt 803 is threadedly connected to the middle of one side of the carrying plate 802. When the carrying plate 802 is moved, the position of the non-woven fabric can be quickly adjusted, reducing the calibration time and thus improving the efficiency of ultrasonic welding of non-woven fabric. One end of the bolt 803 is rotatably connected to a positioning block 804, and an anti-slip pad 805 is provided on one side of the positioning block 804. By simply tightening the bolt 803 and increasing the friction between the positioning block 804 and the guide rod 801 through the anti-slip pad 805, the stability after adjustment is enhanced. The positioning block 804 is slidably connected to the carrying plate 802, and one side of the positioning block 804 is arc-shaped. Loosening the bolt 803 can cause the positioning block 804 to separate from the guide rod 801, thus facilitating the adjustment of the position of the carrying plate 802.

[0024] As shown in Figure 3, a positioning component 9 is provided on the top of the carrier plate 802. 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 picking up or placing non-woven fabric, the spring seat 901 pushes the connecting ear 902, causing the pressure frame 903 to move upward, thereby facilitating the placement of non-woven fabric between the pressure frame 903 and the carrier plate 802. The positioning component 9 also includes a pressure frame 903 and a rubber pad 904. The pressure frame 903 is placed between the connecting ears 902, and the bottom of the pressure frame 903 is provided with a rubber pad 904 to prevent the non-woven fabric from slipping after positioning. The positioning component 9 also includes a side plate 905 and a damping pivot 906. The side plates 905 are slidably connected to both sides of the pressure frame 903, and the upper end of the side plate 905... The positioning assembly 9 includes a damping shaft 906, a side plate 905 fixedly connected to a carrier plate 802, and a sliding connection between the side plate 905 and a connecting ear 902. The side plate 905 limits and guides the connecting ear 902, keeping the pressure frame 903 horizontal. The positioning assembly 9 also includes a handle 907 and a cam 908. The handle 907 is connected to the end of the damping shaft 906, and a cam 908 is provided on the outer side of the damping shaft 906. Pressing down the handle 907 causes the cam 908 to rotate through the damping shaft 906. The cam 908 then presses the pressure frame 903, which can quickly press and position the non-woven fabric, thereby improving the convenience of positioning. The cams 908 are equidistantly distributed on the outer side of the damping shaft 906, and the cams 908 are slidably connected to the pressure frame 903. The arrangement of multiple cams 908 makes the force applied more even.

[0025] [Revised according to Rule 26, August 20, 2024] In summary, when using this non-woven fabric ultrasonic welding device, firstly, according to the structure shown in Figures 1, 2, and 3, push the handle 907 upwards. The damping shaft 906 will drive the cam 908 to rotate. At this time, the spring seat 901 will push the connecting ear 902, causing the pressure frame 903 to move upwards. Secondly, place the non-woven fabric between the pressure frame 903 and the carrier plate 802. After alignment, press down the handle 907, causing it to drive the cam 908 to rotate through the damping shaft 906. The cam 908 will then squeeze the pressure frame 903, quickly pressing and positioning the non-woven fabric. The rubber pad 904 further increases the friction during positioning. Next, start the electric cylinder 4 to drive the ultrasonic welding machine body 5 (and the type...) The ultrasonic welding machine (model 5000IQ, using the same welding principle) moves downward, causing the welding head 7 and lower mold 2 to press against the non-woven fabric. Simultaneously, the ultrasonic generator and ultrasonic transducer inside the main body 5 of the ultrasonic welding machine transmit the vibration through the amplitude transformer 6 to the welding head 7, thereby welding the non-woven fabric. Then, when the position needs to be adjusted, loosening the bolt 803 will cause the positioning block 804 to separate from the guide rod 801. Therefore, the position of the non-woven fabric can be quickly adjusted when moving the carrier plate 802. Finally, after adjusting the position, simply tighten the bolt 803 and use the anti-slip pad 805 to increase the friction between the positioning block 804 and the guide rod 801, thereby enhancing the stability after adjustment, so that the non-woven fabric can be ultrasonically welded again.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
