Technical Field

[0001] This utility model relates to the field of vacuum packaging machine technology, specifically a vacuum packaging machine with a screw fastening device. Background Technology

[0002] Vacuum packaging refers to a packaging method in which the product is placed in an airtight packaging container, the air inside the container is removed, and the sealed container reaches a predetermined vacuum level.

[0003] Most vacuum sealing machines on the market use a double-sided independent snap-fit ​​structure. Before vacuum sealing, the top cover needs to be pressed once on each side to fully snap it onto the machine body, which leads to complicated operation and low work efficiency. In addition, after the existing vacuum packaging machine finishes working, the top cover needs to be opened by pressing the opening buttons on both sides of the machine body to release the pressure and exhaust air from the internal pipelines.

[0004] To address the aforementioned issues, a vacuum packaging machine with a screw-locking device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a vacuum packaging machine with a screw fastener, which solves the problems of complex operation and low work efficiency in the prior art. In addition, the existing vacuum packaging machine requires pressing the cover opening buttons on both sides of the machine body to release the pressure and exhaust air from the internal pipelines before opening the top cover after the work is finished.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vacuum packaging machine with a screw fastener, comprising a base, a top cover rotatably connected to the rear end of the base, a middle upper shell fixedly connected to the bottom of the top cover, a slot opened at the front end of the top cover, a rotating shaft rod passing through and rotatably connected in the slot, a screw fastener cover fixedly connected to the middle of the outer ring of the rotating shaft rod, two limiting brackets fixedly connected to both sides of the top of the middle upper shell, buckles fixedly connected to both ends of both sides of the outer ring of the rotating shaft rod, an air pump fixedly connected to the rear of the top of the middle upper shell, and the air pump is located inside the top cover, hooks fixedly connected to both sides of the top of the base, a lower vacuum groove opened at the top of the base, an upper vacuum groove opened at the bottom of the middle upper shell, the upper vacuum groove corresponding to the lower vacuum groove, an installation groove opened at the bottom of the middle upper shell, an exhaust groove opened on the left side of the upper vacuum groove, an exhaust through hole passing through and opened on the outer side of the exhaust groove, and a circuit board fixedly connected to the top of the middle upper shell, the circuit board being located inside the top cover.

[0007] By adopting the above technical solution, when the rotating shaft rotates, the latches at both ends of its shaft engage with the hooks at the top of the base, tightly locking the upper cover and the base together. The swivel cover, in conjunction with the swivel seat, completes the locking process. At this time, the vacuum chamber (the space formed by the upper vacuum groove and the lower vacuum groove) is completely sealed, preventing air leakage during vacuuming.

[0008] As a further description of the above technical solution: both ends of the rotating shaft are set inside the upper cover, and the rotating shaft passes through and is rotatably connected to the limiting frame.

[0009] By adopting the above technical solution, the limiting frame plays a role in supporting and limiting the rotating shaft.

[0021] By adopting the above technical solution, the working time can be displayed on the screen when the packaging machine is working.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This utility model provides a vacuum packaging machine with a screw-locking device. By pressing down the screw-locking cover, the latches at both ends of the rotating shaft engage with the hooks on both sides of the base, thus locking the machine. By prying the screw-locking cover upwards, the latches at both ends of the rotating shaft disengage from the hooks on both sides of the base, allowing the top cover to be opened. Simultaneously, when the screw-locking cover is closed, the venting silicone moves downwards, blocking the vent hole of the venting groove, thus sealing the vacuum chamber. When the screw-locking cover is pried open upwards, the venting silicone moves upwards, separating from the vent hole of the venting groove, achieving the effect of pressure relief and venting.

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.

[0032] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0033] Reference Figure 1-6This utility model discloses a vacuum packaging machine with a screw-locking device, comprising a base 10, a top cover 1 rotatably connected to the rear end of the base 10, and a middle upper shell 4 fixedly connected to the bottom of the top cover 1. Through holes are provided on both sides of the bottom of the middle upper shell 4 to facilitate the insertion of hooks 11. A slot 2 is provided at the front end of the top cover 1, allowing the screw-locking cover 6 to be easily pried up or down. A rotating shaft 3 is rotatably connected through the slot 2, and the screw-locking cover 6 is fixedly connected to the middle of the outer ring of the rotating shaft 3, enabling the rotating shaft 3 to rotate. Two limiting brackets 5 are fixedly connected to both sides of the top of the middle upper shell 4, serving a limiting function. Buckles 8 are fixedly connected to both ends of the outer ring of the rotating shaft 3, with limiting blocks on the outer side of the buckles 8. One side of the buckle 8 has a through hole through which the rotating shaft 3 passes, while the other side is blocked by the limiting block, facilitating limiting during installation and making the buckle 8 and hook 11 more stable when engaged. An air pump 9 is fixedly connected to the rear top of the upper shell 4, and the air pump 9 is located inside the upper cover 1. Hooks 11 are fixedly connected to both sides of the top of the base 10, serving as limiters. A lower vacuum groove 13 is formed at the top of the base 10, and an upper vacuum groove 15 is formed at the bottom of the upper shell 4. A vacuum chamber is formed between the lower vacuum groove 13 and the upper vacuum groove 15, and a sealing ring is provided at the edge of the vacuum groove to improve the sealing effect. The upper vacuum groove 15 corresponds to the lower vacuum groove 13. An installation groove 21 is formed at the bottom of the upper shell 4 to facilitate the installation of the heating wire 16. An exhaust groove 17 is formed on the left side inside the upper vacuum groove 15, and the exhaust groove 17 communicates with the upper vacuum groove 15. An exhaust vent 18 is formed through the outer side of the exhaust groove 17 to facilitate venting. A circuit board 19 is fixedly connected to the top of the upper shell 4, and the circuit board 19 is located inside the upper cover 1.

[0034] Reference Figure 1-5 Both ends of the rotating shaft 3 are located inside the upper cover 1, and the rotating shaft 3 passes through and is rotatably connected to the limiting frame 5. The limiting frame 5 serves to support and limit the rotating shaft 3. A rotary buckle seat 22 is fixedly connected inside the slot 2, and the rotary buckle seat 22 is located below the rotary buckle cover 6. The rotary buckle seat 22, in conjunction with the rotary buckle cover 6, allows for easy locking of the upper cover 1. An exhaust silicone 7 is fixedly connected to the left side of the outer ring of the rotating shaft 3, and the exhaust silicone 7 is located outside the exhaust hole 18. When the rotary buckle cover 6 is pulled upward, the rotary buckle cover 6 moves the exhaust silicone 7 through the rotating shaft 3, causing it to separate from the exhaust hole 18, thus depressurizing the vacuum chamber and facilitating the opening of the upper cover 1. Two bag clips 14 are fixedly connected inside the lower vacuum groove 13, which can be used to clip the bag opening, preventing it from slipping out. The mounting slot 21 is located in front of the upper vacuum slot 15, and a heating wire 16 is fixedly connected inside the mounting slot 21. A bag-pressing silicone 12 is fixedly connected to the top of the base 10, and the bag-pressing silicone 12 is located in front of the lower vacuum slot 13. The heating wire 16 cooperates with the bag-pressing silicone 12 below to heat the film at the bag opening sandwiched in the middle for easy sealing. A display screen 20 is fixedly connected through the top of the upper cover 1.

[0035] Working principle: Rotate the top cover 1 downwards so that the middle upper shell 4 at the bottom of the top cover 1 fits into the base 10. At this time, the upper vacuum groove 15 at the bottom of the middle upper shell 4 aligns with the lower vacuum groove 13 of the base 10, forming a relatively closed cavity, i.e., a vacuum chamber; the mounting groove 21 of the middle upper shell 4 corresponds to the bag-pressing silicone 12 of the base 10, pressing the bag opening between the two. By pressing down the screw cap 6, the buckles 8 at both ends of the rotating shaft 3 engage with the hooks 11 on both sides of the base 10, thereby locking the machine. When the screw cap 6 is closed, the exhaust silicone 7 will move downwards, blocking the exhaust hole 18 of the exhaust groove 17, so that the vacuum chamber is in a sealed state. At this time, the vacuum chamber is completely sealed to prevent air leakage during vacuuming. The air pump 9 is started. The air pump 9 is connected to the vacuum chamber (the space formed by the upper vacuum groove 15 and the lower vacuum groove 13) through a pipe (not shown in the figure) and begins to extract the air in the chamber and the packaging bag. After the vacuuming is completed, the circuit board 19 controls the heating wire 16 in the mounting groove 21 to be energized and heated. Heating wire 16 works in conjunction with the lower pressure silicone 12 to heat the bag opening film sandwiched in the middle to a molten state. The heating temperature and time are adjusted by circuit board 19 according to the film material to ensure sufficient melting. After heating, heating wire 16 is de-energized, and the pressure between the upper cover 1 and the base 10 is maintained, allowing the molten bag opening film to cool and solidify under pressure, forming a firmly sealed opening to prevent air backflow. After sealing, the screw cap 6 is turned upwards, and the latches 8 at both ends of the rotating shaft 3 separate from the hooks 11 on both sides of the base 10, thereby opening the upper cover 1. When the screw cap 6 is turned upwards, the venting silicone 7 moves upwards, separating from the vent hole 18 of the vent groove 17 to achieve the effect of pressure relief and venting.
