[0002] Sealing the packaging film is a crucial step in the packaging process. Its purpose is to ensure the airtightness of the packaging and protect the contents from external factors.

[0003] Existing sealing equipment takes too long to seal packaging films. This prolonged sealing time causes the packaging film to be continuously heated, absorbing excessive heat and leading to a rise in temperature. Consequently, the packaging film and materials remain at high temperatures for an extended period, exacerbating the temperature rise of the materials and increasing the risk of material adhesion and pipe blockage.

[0009] An ultrasonic transducer is horizontally disposed on one side of the roller, with the welding head at the end of the ultrasonic transducer facing the outer circumferential surface of the roller.

[0010] The second swing seat is parallel to the first swing seat and fixed on the support plate. A second swing assembly is provided on it. The second swing assembly is connected to the ultrasonic transducer and swings under the drive of the drive assembly.

[0013] The first swing plate is horizontally positioned above the first swing seat, with its first end fixedly connected to the upper end of the third rotating shaft. The second end of the first swing plate is provided with a first support plate, which is connected to and passes through the second rotating shaft.

[0014] A first blocking component is disposed on a first swing seat on one side of the first swing plate to limit the swing of the first swing plate.

[0015] A further improvement of this invention is that the second swing component includes:

[0016] The fourth rotating shaft is vertical and mounted on the second swing seat;

[0017] The second swing plate is horizontally positioned above the second swing seat. Its first end is fixedly connected to the upper end of the fourth rotating shaft. The second end of the second swing plate is provided with a second support plate. The first end of the second support plate is fixedly connected to and passes through the ultrasonic transducer.

[0018] The second blocking component is disposed on the second swing seat on one side of the second swing plate and is used to limit the swing of the second swing plate.

[0019] A further improvement of this utility model is that the driving component includes:

[0020] The support is fixed to one side of the second swing seat;

[0021] A cylinder is horizontally fixed on the support platform. A top block is provided at the end of its piston rod. The top block faces the second support plate. When the piston rod extends or retracts, the top block will abut against or disengage from the second support plate.

[0022] A spring is disposed between the second support plate and the support platform. The first end of the spring is fixedly connected to the second end of the second support plate, and the second end of the spring is fixedly connected to the support platform.

[0023] A further improvement of this utility model is that the first blocking component includes:

[0025] The first screw has its first end threadedly connected to and passing through the first baffle plate, and then abuts against the first impact plate at the lower end of the first swing plate. Two first nuts are respectively provided on the first screw on both sides of the first baffle plate.

[0026] A further improvement of this invention is that the second blocking component includes:

[0027] The second baffle plate is fixed on one side of the second swing seat, which is close to the first swing seat;

[0031] This invention provides an ultrasonic rolling friction longitudinal sealing structure. A motor drives a first rotating shaft, which in turn drives a second rotating shaft via a universal coupling. As the second rotating shaft rotates, a roller fixed at its second end also rotates. The rotation of the roller transports the packaging film, moving it within the equipment for sealing. A first oscillating component can fine-tune the position and angle of the second rotating shaft, ensuring good contact between the roller and the packaging film and guaranteeing the stability of the film transport. The drive component drives the second oscillating component to oscillate, allowing the welding head to better adhere to the packaging film. When the packaging film passes between the roller and the welding head, the ultrasonic transducer converts electrical energy into high-frequency mechanical vibration, which is then transmitted to the packaging film through the welding head. This high-frequency vibration causes friction between the molecules of the packaging film, instantly generating heat and achieving rapid sealing. This sealing method is fast, significantly shortening the sealing time compared to existing technologies, reducing the heat absorbed by the packaging film and material, and lowering the degree of material temperature rise, thereby reducing the risk of material adhesion and blockage.

Detailed Implementation

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details.

[0042] The ultrasonic rolling friction longitudinal sealing structure provided by this utility model, in conjunction with the appendix to the instruction manual... Figure 1 To be continued Figure 6 It can be seen that the ultrasonic rolling friction longitudinal sealing structure mainly includes the following parts or components: support plate 10, second rotating shaft 13, first swing seat 14, ultrasonic transducer 15, and second swing seat 16.

[0043] In this invention, a first rotating shaft 111 is horizontally mounted on a support plate 10, and the first rotating shaft 111 rotates under the drive of a motor 11; a second rotating shaft 13 is horizontally mounted, with its first end connected to the end of the first rotating shaft 111 via a universal coupling 12, and a roller 131 fixedly mounted on the second end of the second rotating shaft 13; a first swing seat 14 is fixedly mounted on the support plate 10 below the first rotating shaft 111, and a first swing assembly 20 is mounted on it, which is connected to the second rotating shaft 13; an ultrasonic transducer 15 is horizontally mounted on one side of the roller 131, and the welding head 151 at the end of the ultrasonic transducer 15 is opposite to the outer circumferential surface of the roller 131; a second swing seat 16 is parallel to the first swing seat 14 and fixedly mounted on the support plate 10, and a second swing assembly 40 is mounted on it, which is connected to the ultrasonic transducer 15, and the second swing assembly 40 swings under the drive of a drive assembly 50. A feeding pipe is provided between the roller 131 and the welding head 151, and a packaging film is fitted on the feeding pipe.

[0044] Motor 11 drives the first rotating shaft 111. When the first rotating shaft 111 rotates, it drives the second rotating shaft 13 to rotate via the universal coupling 12. As the second rotating shaft 13 rotates, the roller 131 fixed at its second end also rotates. The rotation of the roller 131 can be used to transport the packaging film, allowing the packaging film to move within the equipment for sealing operations. The first swing assembly 20 can fine-tune the position and angle of the second rotating shaft 13 to ensure good contact between the roller 131 and the packaging film, guaranteeing the stability of the packaging film transport. The drive assembly 50 drives the second swing assembly 40 to swing, allowing the welding head 151 to better adhere to the packaging film. When the packaging film passes between the roller 131 and the welding head 151, the ultrasonic transducer 15 converts electrical energy into high-frequency mechanical vibration, which is then transmitted to the packaging film through the welding head 151. The high-frequency vibration causes friction between the molecules of the packaging film, instantly generating heat and achieving rapid sealing. This sealing method is fast, greatly shortening the sealing time, reducing the heat absorbed by the packaging film and materials, and lowering the degree of material temperature rise, thereby reducing the risk of material sticking and pipe blockage.

[0045] Specifically, the feeding tube can position and guide the packaging film, ensuring that the packaging film is accurately delivered to the sealing position between the roller 131 and the welding head 151.

[0046] As one embodiment, in conjunction with the appendix to the specification Figure 2It is known that the first swing assembly 20 includes a third rotating shaft 21, which is vertically mounted on the first swing seat 14; the first swing plate 22 is horizontally mounted above the first swing seat 14, with its first end fixedly connected to the upper end of the third rotating shaft 21, and the second end of the first swing plate 22 is provided with a first support plate 23, which is connected to and passes through the second rotating shaft 13; the first blocking assembly 30 is provided on the first swing seat 14 on one side of the first swing plate 22 to limit the swing of the first swing plate 22. The first blocking assembly 30 includes a first blocking plate 31, which is fixedly mounted on the side of the first swing seat 14 away from the welding head 151; the first end of the first screw 32 is threadedly connected to and passes through the first blocking plate 31, and abuts against the first impact plate 33 at the lower end of the first swing plate 22; two first nuts 321 are respectively provided on the first screw 32 on both sides of the first blocking plate 31.

[0047] When dealing with packaging films of different diameters, the two first nuts 321 are rotated to move them away from each other. Then, the first screw 32 is rotated to move it away from or closer to the first impact plate 33. After rotating to the appropriate position, the two first nuts 321 are moved closer to each other until the first screw 32 is locked. Then, the first impact plate 33 can swing. When the first impact plate 33 abuts against the first end of the first screw 32, the first impact plate 33 will drive the first swing plate 22, the first support plate 23, the second rotating shaft 13, and the roller 131 to swing to a certain angle, thereby changing the distance between the roller 131 and the welding head 151, thus adapting to packaging films of different diameters.

[0048] Specifically, the feed tube will also change when the diameter of the packaging film changes.

[0049] As one embodiment, in conjunction with the appendix to the specification Figure 2 It is understood that the second swing assembly 40 includes a fourth rotating shaft 41, which is vertically mounted on the second swing seat 16; a second swing plate 42 is horizontally mounted above the second swing seat 16, with its first end fixedly connected to the upper end of the fourth rotating shaft 41, and a second support plate 43 is provided at the second end of the second swing plate 42, with the first end of the second support plate 43 fixedly connected to and passing through the ultrasonic transducer 15; a second blocking assembly is mounted on the second swing seat 16 on one side of the second swing plate 42 to limit the swing of the second swing plate 42. The second blocking assembly includes: a second blocking plate 44 fixedly mounted on one side of the second swing seat 16 near the first swing seat 14; and a first impact rod 451 horizontally fixedly mounted on the second impact plate 45 at the lower end of the second swing plate 42, with one end of the first impact rod 451 abutting against or moving away from the second blocking plate 44.

[0050] During sealing, the drive assembly 50 drives the second support plate 43 and the second swing plate 42 to swing. The second support plate 43 drives the ultrasonic transducer 15 and its welding head 151 to move closer to or away from the packaging film. The ultrasonic transducer 15 converts electrical energy into high-frequency mechanical vibration, which is then transmitted to the packaging film through the welding head 151. The high-frequency vibration causes friction between the molecules of the packaging film, generating heat instantaneously, thus achieving rapid sealing. After sealing, the film quickly leaves the packaging film. During swinging, the first impact rod 451 on the second impact plate 45 impacts the second blocking plate 44, effectively limiting the movement.

[0051] As one embodiment, in conjunction with the appendix to the specification Figure 3 It is known that the drive assembly 50 includes a support 51, which is fixedly mounted on one side of the second swing seat 16; the cylinder 52 is horizontally fixed on the support 51, and its piston rod end is provided with a top block 521, which faces the second support plate 43. When the piston rod extends or retracts, the top block 521 will abut against or disengage from the second support plate 43; the spring 53 is located between the second support plate 43 and the support 51, and the first end of the spring 53 is fixedly connected to the second end of the second support plate 43, and the second end of the spring 53 is fixedly connected to the support 51.

[0052] The piston rod of cylinder 52 extends until the top block 521 abuts against the second support plate 43. The top block 521 drives the second support plate 43 and the second swing plate 42 to approach the first support plate 23. The ultrasonic transducer 15 and its welding head 151 on the second support plate 43 gradually approach the packaging film until the welding head 151 seals the packaging film. At this time, the spring 53 is stretched. Subsequently, the piston rod of cylinder 52 retracts, and the spring 53 also retracts. The spring 53 drives the second support plate 43 to return to its original position. The second support plate 43 drives the second swing plate 42, the ultrasonic transducer 15 and its welding head 151 to return to their original positions simultaneously. This cycle is repeated to continuously seal the packaging.
