Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to a high-speed ultrasonic sealing mechanism. Background Art

[0002] The sealing mechanism is an important part of packaging equipment. The sealing mechanism is mainly used for sealing two layers of packaging base materials, and then sealing the packaged materials in the packaging base materials. The traditional sealing mechanism mainly adopts a heat-sealing component. By the actions of the upper and lower heat-sealing plates, the packaging base materials are tightly pressed between them to achieve the heat-sealing and pressing of the packaging base materials. The defect of this structure is that when performing heat-sealing and pressing, it is necessary to stop the traction of the packaging base materials and wait for the upper and lower heat-sealing plates to complete the heat-sealing process before continuing the traction of the packaging base materials, resulting in an impact on the overall production efficiency of the equipment. Content of the Utility Model

[0003] In view of the deficiencies of the background art, the technical problem to be solved by the utility model is to provide a high-speed ultrasonic sealing mechanism for solving the above problems.

[0004] To this end, the utility model is implemented as follows:

[0005] A high-speed ultrasonic sealing mechanism, including a front traction roller group, is characterized in that: an ultrasonic die head is arranged at the discharge end of the front traction roller group. The ultrasonic die head is connected with a lifting drive assembly. A roller is cooperatively arranged above the ultrasonic die head. Two vertical sealing strips are arranged on the outer side wall of the roller in a circumferential annular arrangement along it, and a transverse sealing strip is arranged along the axial extension of the roller. The transverse sealing strip is located between the two vertical sealing strips. The roller is rotatably arranged on a lifting seat. The lifting seat is connected with a lifting adjustment assembly. A first motor is installed on the lifting seat. The first motor is in transmission connection with the roller.

[0006] A plurality of the transverse sealing strips are arranged at intervals along the circumference of the roller.

[0007] The output end of the first motor is connected with a first gear. The first gear meshes with a second gear. The second gear is connected with the roller.

[0008] The lifting seat is slidably arranged on the frame. The lifting adjustment assembly includes an adjustment screw rod. The adjustment screw rod is rotatably arranged on the frame. One end of the adjustment screw rod presses against the lifting seat. A spring is pressed against the other end of the lifting seat.

[0009] The ultrasonic die head is arranged on a lifting plate. The lifting drive assembly includes a first cylinder. The piston rod of the first cylinder is connected with the lifting plate.

[0010] The high-speed ultrasonic sealing mechanism of the above technical solution performs the sealing operation of the packaging substrate by setting the ultrasonic die head to cooperate with the sealing strip on the roller. During the sealing process, the roller rotates continuously and the packaging substrate can complete the entire sealing operation during continuous traction, replacing the traditional structure of the hot sealing plate for heat sealing. It can effectively achieve high-speed sealing operation, improving the overall packaging efficiency of the equipment and the smoothness of the work. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present utility model has the following drawings:

[0012] Figure 1 It is a schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] As shown in the figure, the high-speed ultrasonic sealing mechanism disclosed by the present utility model includes a front traction roller group 1. An ultrasonic die head 12 is provided at the discharge end of the front traction roller group 1. The ultrasonic die head 12 is connected to a lifting drive assembly. A roller 8 is disposed above the ultrasonic die head 12 in a cooperative manner. There are two vertical sealing strips 10 disposed circumferentially on the outer sidewall of the roller 8, and a horizontal sealing strip 11 disposed axially along it. The horizontal sealing strip 11 is located between the two vertical sealing strips 10. Further, multiple horizontal sealing strips 11 are circumferentially spaced along the roller 8, which can meet the transverse sealing requirements with a reduced interval length. The roller 8 is rotatably disposed on a lifting seat 4. The lifting seat 4 is connected to a lifting adjustment assembly. The lifting seat 4 is slidably disposed on the frame 2. The lifting adjustment assembly includes an adjustment screw 5. The adjustment screw 5 is rotatably disposed on the frame. One end of the adjustment screw 5 presses against the lifting seat 4, and a spring 15 is pressed against the other end of the lifting seat 4. By controlling the rotation of the adjustment screw 5, the lifting seat 4 can be driven to lift or lower under the cooperative action of the spring 15 to adjust the height of the roller 8, thereby adapting to different thicknesses of packaging substrates. A first motor 7 is installed on the lifting seat 4. The first motor 7 is drivingly connected to the roller 8. The output end of the first motor 7 is connected to a first gear 9. The first gear 9 meshes with a second gear 6. The second gear 6 is connected to the roller 8. The ultrasonic die head 12 is disposed on a lifting plate 14. The lifting drive assembly includes a first cylinder 13. The piston rod of the first cylinder 13 is connected to the lifting plate 14. By controlling the first cylinder 13, the lifting plate 14 and the ultrasonic die head 12 can be driven to lift, so that the ultrasonic die head can be lifted to the working height or lowered to the shutdown height.

[0014] The working principle of the present utility model is as follows: The front traction roller group 1 drives the packaging substrate with materials to the ultrasonic die head 12. At this time, the ultrasonic die head 12 cooperates with the vertical sealing strip 10 on the rotating drum 8 to achieve the sealing of the left and right sides of the packaging substrate. The ultrasonic die head 12 cooperates with the horizontal sealing strip 11 on the rotating drum 8 to achieve the sealing of the front and back sides of the packaging substrate. Moreover, the above-mentioned sealing operation can be completed during the continuous backward traction of the packaging substrate.

[0015] With this structure of the present utility model, by setting the ultrasonic die head to cooperate with the sealing strip on the drum for the sealing operation of the packaging substrate, during the sealing process, the drum continuously rotates and the packaging substrate can complete the entire sealing operation during the continuous traction process, replacing the traditional structure of using a heat sealing plate for heat sealing. It can effectively achieve high-speed sealing operation, improving the overall packaging efficiency of the equipment and the smoothness of the work.
