Description

Technical Field

[0001] This utility model discloses a high-efficiency vacuum packaging machine, which belongs to the field of food packaging. Background Technology

[0002] Vacuum packaging machines can automatically extract air from packaging bags and seal them after reaching a predetermined vacuum level. They are commonly used in the food industry because vacuum packaging helps food resist oxidation and thus achieves long-term preservation.

[0003] When using a vacuum packaging machine, the packaged food is placed into the vacuum chamber of the machine. Then, the pressure strip is opened, and the opening edge of the packaging bag is overlapped with the heat sealer used for sealing. The pressure strip is then closed to press down on the edge of the packaging bag to ensure a stable seal. During this process, opening and closing the pressure strip is done manually, which is not only inefficient but also may result in forgetting to close the pressure strip, causing the seal to fail.

[0004] In response to the above problems, a new improvement plan is proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0023] like Figure 1 , Figure 2 As shown, a high-efficiency vacuum packaging machine includes a machine base 1. A heat-sealing component 2 is fixedly installed inside the machine base 1, and a pressure strip 4 is rotatably mounted on the heat-sealing component 2. A sealing cover 3 is rotatably mounted on the machine base 1. When using this product, the material to be vacuum-packaged is placed inside the machine base 1. Then, the pressure strip 4 is manually rotated to lift it. Next, the open side of the packaging bag is placed on the hot air component. Then, the pressure strip 4 is rotated again to press down on the open side of the packaging bag. Finally, the sealing cover 3 is closed. The machine base 1 automatically sucks up the sealing cover 3, and then automatically performs vacuuming and sealing operations on the packaging bag. This is the working process of existing vacuum packaging machines. The machine base of this product... The device is equipped with a transmission mechanism 5, which includes an adjusting belt 51. One end of the adjusting belt 51 is detachably connected to the sealing cover 3. The sealing cover 3 can drive the transmission mechanism 5 to drive the pressure strip 4 through the adjusting belt 51. By setting up the transmission mechanism 5, the movement of the sealing cover 3 is transmitted to the pressure strip 4 through the adjusting belt 51 in the transmission mechanism 5. This allows the pressure strip 4 to be automatically lifted when the sealing cover 3 is opened and automatically rotated when the sealing cover 3 is closed, so that the pressure strip 4 presses down on the packaging bag. This improves the work efficiency and also ensures that the pressure strip 4 will not be forgotten to be closed, resulting in poor sealing. This improves the sealing effect and ensures that the material will not deteriorate prematurely due to air leakage.

[0024] For example Figure 4 and Figure 5As shown, the transmission mechanism 5 also includes a housing 52, a rotating component 53, and a spring 54. The housing 52 is detachably connected to the machine base 1. The end of the adjusting belt 51 away from the sealing cover 3 is fixedly connected to the rotating component 53 and can be wound around the rotating component 53. One end of the rotating component 53 is connected to the pressure strip 4, and the other end of the rotating component 53 is connected to the housing 52 via the spring 54. When no work is being performed or when the work is finished, the machine base 1 will automatically pop up the sealing cover 3. At this time, the sealing cover 3 is suspended at a specific angle and will not rotate due to its own weight. Since the sealing cover 3 is open at a large angle at this time, the adjusting belt 51 is pulled out by the sealing cover 3 to a longer length. During the pulling process, the adjusting belt 51 will drive the rotating part 53 to rotate and release the adjusting belt 51. During the rotation of the rotating part 53, one end of the rotating part 53 will drive the pressure strip 4 to rotate synchronously, that is, lift the pressure strip 4. At the same time, the other end of the rotating part 53 will drive the spring 54 to store power. When the material is placed, during the process of closing the sealing cover 3, the opening angle of the sealing cover 3 gradually decreases, that is, the adjusting belt 51 is no longer subjected to the outward pulling force of the sealing cover 3. At this time, the spring 54 begins to reset, driving the rotating part 53 to reverse and wind the adjusting belt 51. At the same time, it drives the pressure strip 4 to reverse and press the edge of the packaging bag to ensure the sealing effect and avoid air leakage that could cause the material to deteriorate prematurely.

[0025] For example Figure 6 As shown, the rotating component 53 includes a transmission part 531, a winding part 532, and a reset part 533. A protrusion 6 is fixedly connected to the side of the pressure strip 4 near the rotating component 53. A groove 534 is provided on the transmission part 531, and the protrusion 6 can be embedded in the groove 534 and abut against the transmission part 531 for transmission. The adjusting belt 51 is wound on the winding part 532. Baffles 535 are formed on both sides of the winding part 532. The reset part 533 is rotatably connected to the housing 52 through a spring 54. When installing the transmission mechanism 5, the connection can be completed by aligning the groove 534 of the transmission part 531 with the protrusion 6 on the pressure strip 4. At the same time, since the baffles 535 are formed on both sides of the winding part 532, it can be ensured that the adjusting belt 51 will not slip.

[0026] like Figure 3 and Figure 6As shown, mounting plates 7 are fixedly connected to both sides of the housing 52. Mounting plates 7 have mounting holes 71. The machine base 1 has threaded holes that match the mounting holes 71. The housing 52 and the machine base 1 are detachably connected by bolts. After the transmission mechanism 5 and the pressure bar 4 are connected, the housing 52 can be locked onto the machine base 1 by bolts to ensure stability during operation. Similarly, when the transmission mechanism 5 malfunctions, it can be removed from the machine base 1 for easy maintenance. In addition, the machine base 1 has a sliding groove 11. A slider 8 is fixedly connected to the bottom of the housing 52. The slider 8 can extend into the sliding groove 11 and slide therewith. By setting the sliding groove 11 and the slider 8, when installing the transmission mechanism 5, the slider 8 on the housing 52 is first extended into the sliding groove 11, and then the housing 52 is pushed along the sliding groove 11 to move closer to the pressure bar 4. This allows the groove 534 on the transmission part 531 to align with the protrusion 6 on the pressure bar 4, which facilitates the installation process.

[0027] For example Figure 1 As shown, a mounting base 9 is fixedly connected to the sealing cover 3, and a nut is fixedly connected to the mounting base 9. A through hole 511 is opened at one end of the adjusting band 51 near the sealing cover 3. The adjusting band 51 and the mounting base 9 are detachably connected by bolts. Not only are the housing 52 and the machine base 1 detachable, but the adjusting band 51 and the sealing cover 3 are also detachably connected. This design is beneficial for later maintenance and replacement of parts.

[0028] Finally, a bearing 10 is installed between the transmission part 531 and the housing 52, which can improve the smoothness of the rotation process of the rotating part 53.
