Description

Technical Field

[0001] The utility model belongs to the technical field of ultrasonic heat sealing, and particularly relates to a non-woven fabric ultrasonic heat sealing device. Background Art

[0002] Ultrasonic heat sealing uses high-frequency oscillation to transmit sound waves from the welding head to the welding surface of the workpiece. Instantly, the molecules of the workpiece generate friction, reaching the melting point of the plastic, so as to complete the rapid dissolution of solid materials and complete the welding. Most non-woven fabrics use ultrasonic heat sealing for edge sealing.

[0003] In the prior art, a Chinese patent with the publication number CN 212099598 U can be referred to. It discloses a new non-woven fabric ultrasonic heat sealing device, including a workbench and a column. The column is fixed on the workbench, and a control box is fixedly arranged on the workbench. A cylinder is arranged in the control box. It also includes a support roller, a rubber roller, a pressure roller and a fixed column. The fixed column is fixedly connected to the column through an annular sleeve. A heat sealing device is connected to the fixed column. The ultrasonic pressing gear and the pressing device are embedded on the rubber roller. The utility model eliminates the equipment of the previous sewing machine. First, the non-woven fabric bag is heated to the melting point, and then the ultrasonic pressing gear is used for sealing, making the seal more firm.

[0004] This comparative document provides a device for non-woven fabric ultrasonic heat sealing and edge sealing. However, when the above patent is used, it is difficult to ensure that the non-woven fabric is transported and moved according to the heat sealing position, and it is easy to have a position deviation, thus causing the problem of inclination at the sealed edge.

[0005] Therefore, a non-woven fabric ultrasonic heat sealing device is proposed. Summary of the Utility Model

[0008] Preferably, a non-woven fabric ultrasonic heat-sealing device further includes a non-woven fabric cooling plate embedded at a position on the top of the working platform near the high-frequency oscillating welding head, and heat dissipation fins provided at the bottom of the non-woven fabric cooling plate.

[0009] Preferably, the ultrasonic vibrator and the high-frequency oscillating welding head are connected by a horn.

[0010] Preferably, the tops of the fixed seat, the non-woven fabric cooling plate, and the working platform are all on the same horizontal plane.

[0011] Preferably, both the non-woven fabric cooling plate and the heat dissipation fins are integrally cast from aluminum alloy.

[0012] Preferably, one end of the ball screw penetrates through the fixed seat, and the disc is located outside the fixed seat.

[0013] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects:

[0014] Through the non-woven fabric conveying and limiting assembly, the position of the limiting plate can be adjusted according to the position of the non-woven fabric edge sealing, so that the non-woven fabric moves along a straight line during the pushing and conveying process, thereby ensuring the accuracy of the subsequent non-woven fabric heat-sealing part, avoiding the inclination of the heat-sealing part, ensuring the quality of the edge sealing, reducing the generation of defective products. Through the non-woven fabric cooling plate, the heat on the non-woven fabric after heat-sealing can be absorbed, so that the non-woven fabric is quickly cooled and solidified, improving the quality of the non-woven fabric after heat-sealing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "comprising" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] An embodiment of the present utility model provides a non-woven fabric ultrasonic heat-sealing device, as Figures 1-4 shown, which includes a working platform 1. The bottom of the working platform 1 is fixedly connected to the fuselage 2 by bolts, and the top of the working platform 1 is fixedly connected to the machine head 3 by bolts. A flower wheel 4 is rotatably connected to the bottom of the machine head 3. An ultrasonic vibrator 5 is fixedly connected to the inner wall of one side of the fuselage 2 by bolts. A high-frequency oscillating welding head 6 is provided at the output end of the ultrasonic vibrator 5. The ultrasonic vibrator 5 and the high-frequency oscillating welding head 6 are connected by a horn. A fixed seat 71 in the non-woven fabric conveying and limiting assembly 7 is fixedly connected to the outer wall of one side of the working platform 1 by bolts. And a scale line 72 is drawn at a position on the top of the working platform 1 close to the fixed seat 71. A ball screw 73 is rotatably connected to the inner wall of one side of the fixed seat 71. A disc 74 is welded to one end of the ball screw 73. One end of the ball screw 73 penetrates through the fixed seat 71. The disc 74 is located outside the fixed seat 71. A nut seat on the ball screw 73 is fixedly connected to a moving table 75 by a nut. A limiting plate 76 is rotatably connected to the inner wall of one side of the moving table 75.

[0023] It should be noted that since it is difficult for the existing non-woven fabric ultrasonic heat-sealing device to ensure that the non-woven fabric is conveyed and moved according to the heat-sealing position, it is easy to have a position deviation, which will cause the problem of inclination at the sealing edge. In this embodiment, the non-woven fabric conveying and limiting assembly 7 can adjust the position of the limiting plate 76 according to the position of the non-woven fabric sealing edge (the interval between the heat-sealing edge and the side of the non-woven fabric), so that the non-woven fabric moves linearly when being pushed and conveyed, thereby ensuring the accuracy of the subsequent heat-sealing part of the non-woven fabric, avoiding inclination at the heat-sealing part, ensuring the quality of the sealing edge, and reducing the generation of defective products.

[0024] Specifically, in this embodiment, the solution mainly includes a non-woven fabric conveying and limiting assembly 7. When performing the heat-sealing edge operation on the non-woven fabric, the position of the limiting plate 76 is adjusted according to the width of the heat-sealing edge of the non-woven fabric. The disc 74 is rotated, the disc 74 drives the ball screw 73 to rotate, the nut seat on the ball screw 73 moves linearly, and the moving table 75 on the nut seat moves linearly synchronously. The position of the limiting plate 76 is accurately adjusted according to the value on the scale line 72. After reaching the required position, the limiting plate 76 is rotated 90 degrees towards the working platform 1, and the limiting plate 76 rotates to the top of the working platform 1. At this time, one side edge of the non-woven fabric is attached to the outer side wall of the limiting plate 76, and the edge-sealing position on the non-woven fabric is on one side of the flower wheel 4. After pressing the non-woven fabric with the palm and pushing it along the limiting plate 76, the non-woven fabric is conveyed above the high-frequency oscillating welding head 6. The pedal on the fuselage 2 is stepped on to make the ultrasonic vibrator 5 work to generate vibration and transmit it to the high-frequency oscillating welding head 6. The high-frequency oscillating welding head 6 transmits ultrasonic waves to the non-woven fabric to make it heat-melt, and the flower wheel 4 rotates to squeeze the heat-melted parts together to achieve the edge-sealing of the non-woven fabric.

[0025] An embodiment of the utility model provides a non-woven fabric ultrasonic heat-sealing device, as Figure 1 and Figure 3 shown, which includes a working platform 1. A non-woven fabric cooling plate 8 is embedded at a position on the top of the working platform 1 close to one side of the high-frequency oscillating welding head 6. Heat dissipation fins 9 are arranged at the bottom of the non-woven fabric cooling plate 8. Both the non-woven fabric cooling plate 8 and the heat dissipation fins 9 are integrally cast from aluminum alloy.

[0026] Specifically, in this embodiment, when the heat-melted and fixed non-woven fabric moves to the non-woven fabric cooling plate 8, heat exchange occurs between the non-woven fabric cooling plate 8 and the non-woven fabric. The non-woven fabric cooling plate 8 absorbs heat, and the non-woven fabric is quickly cooled and solidified, and the heat absorbed by the non-woven fabric cooling plate 8 is quickly transferred to the air through the heat dissipation fins 9.

[0027] In a further preferred embodiment of the utility model, as Figure 1 shown, the top surfaces of the fixed seat 71, the non-woven fabric cooling plate 8, and the working platform 1 are all on the same horizontal plane.

[0028] In this embodiment, the limiting plate 76 can be rotated to the top of the working platform 1, and the non-woven fabric cooling plate 8 and the non-woven fabric can be effectively contacted to achieve the cooling of the non-woven fabric.
