DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 A plastic packaging sealing device in this embodiment includes a base 1, a support frame 3 is fixedly connected to the top of the base 1, a working hole 17 is opened in the base 1, a support leg 2 is fixedly connected to the bottom of the base 1, and adjustment structures are provided on the support leg 2 and the base 1.

[0021] The adjustment structure includes a connecting frame 8, a servo motor 7, a limiting rod 9, a threaded rod 10 and a sleeve 11. The connecting frame 8 is fixedly connected to the supporting leg 2, the servo motor 7 is fixedly connected in the connecting frame 8, the output end of the servo motor 7 is on the left side, the threaded rod 10 is fixedly connected to the output end of the servo motor 7, the sleeve 11 is threadedly connected to the outside of the threaded rod 10, and the limiting rod 9 passes through the sleeve 11 and is fixedly connected to the supporting leg 2.

[0022] The adjusting structure is movably displaced on the base 1 through the working hole 17 .

[0023] In this embodiment, a cylinder 4 is arranged on the support frame 3 , the output end of the cylinder 4 is in the downward direction, a mounting seat 5 is fixedly connected to the output end of the cylinder 4 , and a hot pressing sealing plate 6 is arranged at the bottom of the mounting seat 5 .

[0024] The hot-pressed sealing plate 6 is a plate used to seal and seal containers, and is usually used in the food, pharmaceutical, chemical and other industries. This sealing plate completes the sealing through two processes of heating and pressure, ensuring the safety, hygiene and integrity of the products in the closed container during storage and transportation.

[0025] The specific working principle is to fit the container mouth tightly with the hot press sealing plate 6, and then heat the sealing plate through a heating device to soften its material or melt the sealing material. At the same time, pressure is applied to make the sealing plate and the container mouth bond together to form a strong sealing layer. After cooling, the sealing plate solidifies, providing a tough, sealed seal to prevent the intrusion of external substances such as air, moisture, bacteria, etc.

[0026] The hot-pressed sealing plate 6 is usually made of polymer materials, such as polypropylene, polyethylene, etc. These materials have good heat resistance, chemical resistance and corrosion resistance, and can meet the packaging requirements of different products. The design of the sealing plate should take into account the size and shape of the container and the requirements of the sealing material to ensure that the sealing effect is firm and reliable.

[0027] During the sealing process, operators need to strictly follow the operating procedures to ensure the quality of sealing. In addition, hot press sealing equipment also needs regular maintenance and calibration to ensure the consistency and stability of the sealing effect.

[0028] In short, the hot-pressing sealing plate 6 is an important component for achieving container sealing, which achieves sealing through heating and pressure to ensure product quality and safety.

[0029] In this embodiment, a through hole 12 is opened inside the sleeve 11 , and the limiting rod 9 passes through the sleeve 11 through the through hole 12 .

[0031] In this embodiment, a protective cover 14 is fixedly connected to the upper end of the sleeve 11 , and a driving motor 15 is fixedly connected inside the protective cover 14 .

[0032] In this embodiment, the output end of the driving motor 15 is directed upward, and the output end of the driving motor 15 is fixedly connected to the workbench 16 .

[0033] Among them, the plastic packaging to be processed is placed on the workbench 16.

[0035] There are eight adsorption holes 20 .

[0036] The working principle of the above embodiment is:

[0037] First, the cylinder 4 drives the mounting seat 5 and the hot-pressing sealing plate 6 to move and perform hot-pressing sealing on the plastic package.

[0038] Secondly, the plastic package is placed on the workbench 16 , and the workbench 16 is adsorbed by the adsorption box 19 in cooperation with the fan 22 , and the plastic package placed on the workbench 16 is adsorbed and limited by the adsorption holes 20 on the workbench 16 .

[0039] Finally, the threaded rod 10 is driven to rotate through the operation of the servo motor 7, and the rotation of the threaded rod 10 drives the sleeve 11 to move. The sleeve 11 is limited by the limit rod 9, and the sleeve 11 drives the protective cover 14 to move. The protective cover 14 drives the driving motor 15 to move. The driving motor 15 can drive the workbench 16 to move and adjust the processing direction. After the driving motor 15 drives the workbench 16 to rotate, the direction of the plastic packaging sealing processing can be increased, thereby enhancing the sealing efficiency of the plastic packaging sealing device and other advantages.
