[0013] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0014] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0015] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0016] Please see Figure 1-5 The present invention relates to an automatic pressing vacuum sealing machine, comprising: The machine body 1 has a main control board, a motor 11, a driven component 12 and a hook 13 on its inner wall. The main control board is used to receive signals and control the motor 11 to rotate. One end of the driven component 12 is fixedly connected to the motor 11 and the other end is fixedly connected to the hook 13. The first surface of the machine body 1 is also provided with a vacuuming device 17 and a heating device 18 that are electrically connected to the main control board. The pressure cover 2 is rotatably disposed on the first surface of the body 1, and the side of the pressure cover 2 close to the body 1 is provided with a snap-fit ​​21. The snap-fit ​​21 is movably sleeved with a rotating shaft 212, and the hook 13 is snapped into the rotating shaft 212. The machine body 1 is provided with a slot 14 for the card connector 21 to pass through. When the cover 2 closes the machine body 1, the motor 11 is started. The card connector 21 passes through the slot 14 and is engaged with the hook 13 through the rotating shaft 212. The motor 11 drives the hook 13 to rotate to tighten the card connector 21.

[0017] The following describes the solution of this application in a specific usage scenario: The user places the product to be sealed on the first surface of the machine body 1 and closes the machine body 1 with the pressure cap 2, starts the machine body 1, and after receiving the start signal, the main control board controls the motor 11 to start rotating. The driven component 12, which is fixedly connected to the motor 11, drives the hook 13 to rotate, and the hook 13 then engages with the engaging component 21. As the hook 13 rotates, the engagement between the hook 13 and the engaging component 21 becomes tighter, and the engaging component 21 drives the pressure cap 2 to tightly close the machine body 1. After the pressure cap 2 tightly closes the machine body 1, the vacuum device 17 quickly works, extracting the air from the packaging bag through the vacuum pipeline system inside the machine body 1 to form a vacuum environment, effectively extending the shelf life of the food. The heating device 18 applies appropriate temperature and pressure at the sealing point to ensure that the sealing edge of the packaging bag is tightly adhered, preventing air and moisture from entering and maintaining the freshness and integrity of the items inside the packaging. With the cooperation of the hook 13 and the snap-fit ​​21, the cap 2 is firmly locked onto the first surface of the body 1. This design not only simplifies the sealing operation but also improves sealing efficiency and sealing effect. The user only needs to start the motor, and the entire sealing process can be completed automatically, greatly saving time and effort. The vacuuming device 17 and the heating device 18 both adopt existing technology equipment. For example, the vacuuming device 17 can be a mechanical pump, and the heating device 18 can be an electric heating wire.

[0018] In this embodiment, the driven component 12 includes a rotating gear 121, a driven gear 122, and a driven shaft 123. The rotating gear 121 is fixedly connected to the output shaft of the motor 11 and meshes with the driven gear 122. The driven shaft 123 passes through the driven gear 122 and is fixedly connected to it. Both ends of the driven shaft 123 are fixedly connected to the latches 13. When the rotating gear 121 rotates with the output shaft of the motor 11, its meshing relationship drives the driven gear 122 to rotate synchronously. The rotation of the driven gear 122 then drives the driven shaft 123, which is fixedly connected to it, to rotate. Since both ends of the driven shaft 123 are fixedly connected to the latches 13, the latches 13 also rotate with the driven shaft 123. This precise mechanical linkage design ensures that the latches 13 can rotate accurately and stably, and achieve a tight engagement with the latching member 21 at the appropriate time, thereby effectively locking the pressure cap 2 on the first surface of the body 1. The design of the entire driven component 12 not only improves the automation level of the sealing machine, but also ensures the stability and reliability of the sealing process.

[0019] In this embodiment, the hook 13 includes an abutting end 131 and a fixed end 132. The width of the hook 13 gradually increases from the abutting end 131 to the fixed end 132. The fixed end 132 is fixedly connected to the driven shaft 123, and the abutting end 131 engages with the locking member 21. Specifically, during rotation, the abutting end 131 of the hook 13 gradually approaches the locking member 21 until it is finally tightly engaged. Due to the gradual increase in width of the hook 13, the abutting end 131 provides a larger contact area and a more stable locking force when it contacts the locking member 21, thereby enhancing the locking firmness of the cap 2. In addition, the firm connection between the fixed end 132 and the driven shaft 123 ensures the stability and reliability of the hook 13 during rotation, avoiding sealing problems caused by loosening or displacement, and improving the overall performance of the sealing machine.

[0020] In this embodiment, the pressure cap 2 is provided with a fixed shaft; the snap-fit ​​component 21 forms a connecting end 213 and a snap-fit ​​end 211, the connecting end 213 is hinged to the fixed shaft and the fixed shaft is fitted with a torsion spring, one end of the torsion spring abuts against the pressure cap 2 and the other end abuts against the connecting end 213; the rotating shaft 212 is fitted onto the snap-fit ​​end 211. The snap-fit ​​component 21 has a certain elastic reset function under the action of the torsion spring. When the pressure cap 2 is pressed down, the snap-fit ​​component 21 is subjected to external force, the connecting end 213 rotates around the fixed shaft, and the torsion spring deforms and stores energy; when the external force disappears or weakens, the torsion spring releases the stored energy and pushes the snap-fit ​​component 21 to reset. The setting of the rotating shaft 212 allows the snap-fit ​​end 211 to rotate flexibly when subjected to the thrust of the hook 13, so as to adapt to the rotation and snap-fit ​​action of the hook 13, further improving the stability and reliability of the snap-fit. Overall, this design not only enhances the automation level of the sealing machine, but also significantly improves the stability and efficiency of the sealing process.

[0021] In this embodiment, the inner wall of the body 1 is also provided with a first micro switch 15 and a second micro switch 16 electrically connected to the main control board. The first micro switch 15 is located adjacent to the front of one of the hooks 13, and the second micro switch 16 is located adjacent to the back of the other hook 13. When the hook 13 touches the first micro switch 15 during the process of releasing the latching member 21, the main control board receives a signal and then controls the motor to stop rotating, and the hook 13 also stops rotating. Similarly, when the other hook 13 hooks the latching member 21 and rotates until it touches the second micro switch 16, the main control board also receives a signal and controls the motor to stop rotating, and the hook 13 also stops rotating. The setting of these two micro switches not only realizes the real-time feedback of the position of the hook 13, but also ensures the precise control of the sealing action.

[0022] In this embodiment, the first surface of the machine body 1 is also provided with function buttons electrically connected to the main control board. These function buttons are used to control the motor 11, the vacuum device 17, and the heating device 18. Users can start or stop the motor 11 by operating the function buttons. Once the motor 11 starts, the vacuum device 17 and the heating device 18 are immediately activated. This design makes the operation of the sealing machine more intuitive and convenient, allowing users to use it without complex training. Furthermore, the electrical connection between the function buttons and the main control board ensures rapid and accurate signal transmission, thereby improving the overall response speed and operational precision of the sealing machine.

[0023] The advantages of this utility model are: This invention features a motor that drives the hook to rotate, and the motor is precisely controlled by the main control board, allowing the hook to automatically engage with the fastener. Through the interlocking action between the hook and the fastener, the pressure cap is further tightened and pressed against the machine body, effectively replacing the traditional manual pressing operation, significantly improving ease of operation, and achieving labor-saving results.

[0024] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
