Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to an ultrasonic sealing packaging machine. Background Technology

[0002] An ultrasonic sealing and packaging machine is a device that uses the frictional heat energy generated by high-frequency vibration (usually 20~40kHz) to partially fuse plastic films. It achieves rapid and pollution-free sealing through a combination of mechanical pressure and ultrasonic energy. Its core components include an ultrasonic generator, transducer, amplitude transformer, and sealing head. No additional heating elements are required during operation. It is suitable for continuous sealing of thermoplastic materials such as PE, PP, and PET, and is particularly suitable for industries with high cleanliness requirements, such as food and medical industries. It offers advantages such as high sealing strength, low energy consumption, and no smoke or dust.

[0003] Traditional ultrasonic sealing machines generally use a rigid pressure plate design, using cylinders or mechanical drives to press down the pressure head and perform ultrasonic sealing. However, in actual operation, due to the lack of a pre-positioning mechanism, operators must continuously manually fix the packaging bag to prevent displacement or deformation during the sealing process. This not only increases the complexity of operation but also affects production efficiency and sealing accuracy. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic sealing and packaging machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic sealing and packaging machine, including a control console, and further comprising: A control panel fixed to the front of the console has a support base fixedly connected to the rear side of the top of the console, a fixing plate fixedly connected to the top of the support base, a hydraulic rod fixedly connected to the top of the fixing plate, a support leg fixedly connected to one side of the bottom of the console, and a positioning plate fixedly connected to the top of the hydraulic rod. An ultrasonic sealing machine is fixed to the bottom of a positioning plate. A pressing block is installed at the bottom of the ultrasonic sealing machine. A connecting frame is provided on one side of the pressing block. A positioning component is fixedly connected to the bottom of the connecting frame. The positioning component includes a guide plate.

[0006] Preferably, a limiting plate is fixedly connected to the top of the fixing plate, and the surface of the limiting plate is slidably connected to the interior of the positioning plate.

[0007] Preferably, a first clamping plate and a second clamping plate are respectively provided on the front and rear sides of the pressing block. A lead screw is rotatably connected to both sides inside the first clamping plate. A torsion block is fixedly connected to one end of the lead screw, and a retaining ring is fixedly connected to the other end of the lead screw. A limiting groove for use with the retaining ring is opened inside the second clamping plate.

[0008] Preferably, a rubber plate is fixedly connected between the opposite sides of the first and second plates to increase the friction between them and the pressing block, and one side of the first plate is fixedly connected to the connecting frame.

[0009] Preferably, the guide plate is fixed to one side of the connecting frame, a plurality of springs are fixedly arranged in an array at the bottom of the guide plate, a pressure plate is fixedly connected to the bottom of the springs, and a limiting post is fixedly connected to the top of the pressure plate and slidably connected to the inside of the guide plate.

[0010] Preferably, the bottom array of the pressure plate is fixed with multiple rubber strips, and the top of the limiting post is fixedly connected with a connecting ring for limiting the stroke of the pressure plate.

[0011] Preferably, a reinforcing rib is fixedly connected to one side of the guide plate, and one side of the reinforcing rib is fixedly connected to the connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When the pressing block moves downward, the first and second clamping plates work together to drive the connecting frame and guide plate to descend synchronously. During this process, the pressure plate contacts the item to be sealed before the pressing block and applies pre-pressure. As the pressing block continues to press down, the spring gradually compresses and generates increasing buffering force. This progressive pressurization mechanism can ensure the accurate positioning of the item to be sealed and effectively prevent displacement during the sealing process, thereby significantly improving sealing quality and operational stability.

Detailed Implementation

[0015] 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.

[0016] Please see Figures 1-4 As shown, an ultrasonic sealing and packaging machine includes a control console 1, and also includes: A control panel 2 is fixed to the front side of the control panel 1. A support base 3 is fixedly connected to the rear side of the top of the control panel 1. A fixing plate 4 is fixedly connected to the top of the support base 3. A hydraulic rod 5 is fixedly connected to the top of the fixing plate 4. A support leg 6 is fixedly connected to one side of the bottom of the control panel 1. A positioning plate 7 is fixedly connected to the top of the hydraulic rod 5. An ultrasonic sealing machine 8 is fixed to the bottom of the positioning plate 7. A pressing block 9 is installed at the bottom of the ultrasonic sealing machine 8. A connecting frame 10 is provided on one side of the pressing block 9. A positioning component 11 is fixedly connected to the bottom of the connecting frame 10. The positioning component 11 includes a guide plate 1101. The control console 1 establishes an electrical connection with the ultrasonic sealing machine 8 and the hydraulic rod 5 through the integrated control panel 2, forming a complete intelligent control system. The operator can accurately adjust the downward stroke of the hydraulic rod 5 and the working parameters of the ultrasonic sealing machine 8, such as frequency, power and sealing time, through the control panel 2 to achieve one-button automated sealing operation. This is existing technology, which is clearly known to those skilled in the art and will not be described in detail here. The hydraulic rod 5 is supported by the support base 3 and the fixing plate 4. The fixing of the hydraulic rod 5 to the positioning plate 7 facilitates the up and down adjustment of the ultrasonic sealing machine 8 and the sealing with the pressing block 9. The connecting frame 10 facilitates the installation of the positioning component 11. The positioning component 11 is conveniently pressed against the surface of the item to be sealed before the sealing operation to prevent movement during the sealing process.

[0017] A limiting plate 12 is fixedly connected to the top of the fixed plate 4. The surface of the limiting plate 12 is slidably connected to the interior of the positioning plate 7. A first clamping plate 13 and a second clamping plate 14 are respectively provided on the front and rear sides of the pressing block 9. A screw rod 15 is rotatably connected to both sides inside the first clamping plate 13. A torsion block 16 is fixedly connected to one end of the screw rod 15, and a retaining ring 17 is fixedly connected to the other end of the screw rod 15. A limiting groove 18 is opened inside the second clamping plate 14 to cooperate with the retaining ring 17. A rubber plate 19 is fixedly connected between the opposite sides of the first clamping plate 13 and the second clamping plate 14 to increase the friction between them and the pressing block 9. One side of the first clamping plate 13 is fixedly connected to the connecting frame 10. Through the sliding connection between the limiting plate 12 and the positioning plate 7, the positioning plate 7 is driven by the hydraulic rod 5 to cooperate with the ultrasonic sealing machine 8 to perform sealing work. During the up-and-down movement, the positioning plate 7 will limit the movement on the surface of the limiting plate 12, thereby improving the stability of the ultrasonic sealing machine 8 when it moves up and down. When the user needs to fix the first clamping plate 13 and the second clamping plate 14 on the pressing block 9 to install the positioning component 11, the screw 15 inside the first clamping plate 13 is engaged with the inside of the limiting groove 18, and the first clamping plate 13 and the second clamping plate 14 are framed on the surface of the pressing block 9 with the rubber plate 19. Then, the torsion block 16 is rotated to make the screw 15 rotate to drive the retaining ring 17 to move. When the retaining ring 17 moves to the moving distance, it will press against the inside of the limiting groove 18, thereby achieving the effect of tight installation. Similarly, it is also convenient to install on pressing blocks 9 of different specifications. It should be noted that it can be installed on pressing blocks 9 smaller than those shown in the figure.

[0018] A guide plate 1101 is fixed to one side of the connecting frame 10. Multiple springs 1102 are arrayed and fixed to the bottom of the guide plate 1101. A pressure plate 1103 is fixedly connected to the bottom of each spring 1102. A limiting post 1104, which slides inside the guide plate 1101, is fixedly connected to the top of the pressure plate 1103. Multiple rubber strips 1105 are arrayed and fixed to the bottom of the pressure plate 1103. A connecting ring 1106, used to limit the stroke of the pressure plate 1103, is fixedly connected to the top of the limiting post 1104. A reinforcing rib 1107 is fixedly connected to one side of the guide plate 1101. One side of the reinforcing rib 1107 is fixedly connected to the connecting frame 10. The guide plate 1101 is fixed to one side of the connecting frame 10, facilitating its engagement with the first clamping plate 13 to fix it onto the pressing block 9. Then, during the descent of the pressing block 9... The pressure plate 1103 contacts the item to be sealed before the pressing block 9 and applies pre-pressure. The rubber strip 1105 reduces friction damage during pressure. As the pressing block 9 continues to press down, the spring 1102 gradually compresses and generates increasing buffering force. This progressive pressurization mechanism ensures accurate positioning of the item to be sealed and effectively prevents displacement during the sealing process, thereby significantly improving sealing quality and operational stability. During the movement of the pressure plate 1103, the limiting post 1104 slides within the guide plate 1101, thereby increasing the temperature of the pressure plate 1103 during movement. The reinforcing rib 1107 is fixed between the connecting frame 10 and the guide plate 1101, which improves the connection strength between the two and ensures stability and durability after long-term use.

[0019] Working principle: First, when the user needs to fix the first clamping plate 13 and the second clamping plate 14 onto the pressing block 9 to install the positioning component 11, the screw 15 inside the first clamping plate 13 is engaged inside the limiting groove 18, and the first clamping plate 13 and the second clamping plate 14 are framed on the surface of the pressing block 9 with the rubber plate 19. Then, the torsion block 16 is rotated to make the screw 15 rotate, thereby driving the retaining ring 17 to move. When the retaining ring 17 moves to the moving distance, it will press against the inside of the limiting groove 18, thereby achieving the effect of fastening the installation. Then, when performing the sealing work, the hydraulic rod 5 is opened to drive the positioning plate 7 to descend. At this time, the positioning plate 7 will be limited during the up and down movement. The surface of the positioning plate 12 is limited to move, thereby improving the stability of the ultrasonic sealing machine 8 when it moves up and down. During the descent of the ultrasonic sealing machine 8, it moves in conjunction with the pressing block 9. When the pressing block 9 descends, the pressure plate 1103 contacts the item to be sealed before the pressing block 9 and applies pre-pressure. The rubber strip 1105 can reduce friction damage caused by pressure. As the pressing block 9 continues to press down, the spring 1102 is gradually compressed and generates an increasing buffer force. This progressive pressurization mechanism can ensure the accurate positioning of the sealed item and effectively prevent displacement during the sealing process, thereby significantly improving the sealing quality and operational stability.
