[0038] When in use, the lifting drive mechanism 7 drives the lifting door 1 to move upward or downward via the lifting plate 70 to switch the open and closed states; the connecting assembly 8 between the lifting plate 70 and the top surface of the lifting door 1 combined with the guide groove 31 on the vertical beam 3 provides a free margin for the lifting door 1 to fit toward the sealing box when closing, effectively ensuring the reliable fit between the lifting door 1 and the sealing box, and enabling rapid opening and closing while ensuring sealing performance.

[0039] like Figure 3 and Figure 4 As shown, the structure of the connecting component 8 is: it includes a vertically arranged connecting rod 83, an L-shaped plate 81 is installed on the side of the lifting plate 70, a support 85 is installed on the top surface of the lifting door 1, a rotating structure 1 82 is installed between the top end of the connecting rod 83 and the L-shaped plate 81, and a rotating structure 2 84 is installed between the bottom end of the connecting rod 83 and the support 85; the axes of the rotating structure 1 82 and the rotating structure 2 84 are parallel and are arranged along the width direction of the corresponding lifting door 1.

[0040] In this embodiment, the upper and lower ends of the connecting component 8 respectively form a rotating mounting structure with the lifting plate 70 and the lifting door 1, that is, the lifting plate 70 can be lifted and lowered to pull the lifting door 1 synchronously, and sufficient space can be provided during the lifting process, which not only ensures the smooth and stable lifting process, but also helps to ensure the reliable fit between the lifting door 1 and the sealing box.

[0041] like Figure 5 As shown, guide wheel groups 9 are respectively installed at the four corners of the lifting door 1, and two sets of upper and lower identical guide grooves 31 are opened on the single vertical beam 3, so that the upper and lower sets of guide wheel groups 9 on the same vertical side of the lifting door 1 can be matched and matched, effectively ensuring the reliable matching between the lifting door 1 and the vertical beams 3 on both sides, and ensuring the stability and smoothness of the lifting door 1 during the lifting, opening and closing process.

[0042] In this embodiment, the guide wheel set 9 is combined with the guide groove 31 to limit the lifting path of the lifting door 1, effectively ensuring that the opening and closing switching of the lifting door 1 is smooth, reliable, stable and controllable.

[0043] like Figure 6 As shown, the structure of the single guide wheel group 9 is: including a wheel group 1 91 extending vertically into the guide groove 31, and a wheel group 2 92 arranged perpendicular to the plane of the lifting door 1; the circumferential wall surface of the wheel group 1 91 is tangent to the side wall surface of the guide groove 31 to form a guide structure, and the circumferential wall surface of the wheel group 2 92 is in contact with the side surface of the vertical beam 3 to form a guide structure; the axes of the wheel group 1 91 and the wheel group 2 92 are perpendicular.

[0044] When in use, the wheel set 1 91 moves along the guide groove 31 , and the wheel set 2 92 is tangentially attached to the wall surface of the vertical beam 3 , which effectively ensures that the lifting door 1 is smooth and stable during the lifting process.

[0045] The bottom end of the single guide groove 31 is bent and extended toward the sealing box to form an inner curved portion 32 , and the lifting door 1 is urged to fit toward the sealing box via the inner curved portion 32 .

[0046] By providing the inner curved portion 32 on the guide groove 31 in combination with the connecting assembly 8, the lifting door 1 can be fitted toward the sealing box when it is lowered into position relative to the sealing box, thereby helping to ensure the sealing performance of the fitting.

[0047] In this embodiment, the deadweight of the lifting door 1 is cleverly utilized, combined with the inward guidance of the inner curved portion 32, to effectively ensure the reliability of the fitting of the lifting door 1 toward the sealing box.

[0048] In this embodiment, sealing strips and other sealing members can be installed between the sides of the lifting door 1 facing the sealing box according to actual use requirements, so as to further ensure the sealing performance while fitting.

[0049] Guide pillars 6 are vertically installed at intervals on the top surface of the working platform 2, and support plates 61 are installed on the top of the guide pillars 6, and a base plate is installed on the bottom ends of the guide pillars 6 located at the working platform 2; the lifting plate 70 is slidably assembled with the guide pillars 6 on both sides to form a guide structure that moves up and down, and the lifting drive mechanism 7 is installed between the base plate and the support plate 61.

[0050] In this embodiment, the guide pillar 6 not only realizes the overhead layout and installation of the lifting drive mechanism 7, which helps to realize the lifting, opening and closing switching of the lifting door 1, but also provides a stable and reliable structural guide for the up and down movement of the lifting plate 70.

[0051] The structure of the lifting drive mechanism 7 is as follows: it includes a motor 73 installed on the support plate 61, the output end of the motor 73 is arranged horizontally and connected to a driving wheel, which is rotatably installed on the side of the support plate 61; a driven wheel is rotatably installed on the side of the bottom plate, and the driving wheel and the driven wheel are jointly wound with a synchronous belt to form a synchronous belt transmission assembly 72; the lifting plate 70 is fixed on the synchronous belt via the pressure plate assembly 71. When in use, the synchronous belt transmission assembly 72 is driven by the operation of the motor 73, and the lifting plate 70 moves up or down with the different transmission directions of the synchronous belt.

[0052] In this embodiment, the pressure plate assembly 71 is a commercially available standard product, which is used to fix the lifting plate 70 relative to the synchronous belt to move synchronously.

[0053] Two adjacent sides of the sealed box are equipped with lifting doors 1 , and the lifting doors 1 on both sides are symmetrically installed on the two ends of the lifting plate 70 via connecting components 8 . The lifting doors 1 on both sides are driven by the lifting drive mechanism 7 to rise and fall synchronously.

[0054] In this embodiment, the lifting drive mechanism 7 synchronously drives the lifting doors 1 on both sides to open and close, achieving a one-drive-two effect, making it convenient to load and unload materials inside the sealed box from different side doors.

[0055] The working platform 2 is equipped with a vacuum pumping assembly 5 and a vacuum breaking tube 40 which are connected to the inside of the sealing box, and also includes a pressing mechanism 4 which switches the on and off state of the vacuum breaking tube 40 .

[0056] In this embodiment, the vacuum pumping assembly 5 is used to extract the air in the sealed box to achieve a preset vacuum state to ensure the preset vacuum requirement in packaging production; the vacuum breaking tube 40 is used to connect the inside and outside of the sealed box to break the vacuum in the box.

[0057] In this embodiment, when the sealed box is in a vacuum state, the vacuum breaking tube 40 is pressed by the pressing mechanism 4 to disconnect the connection with the outside air. In actual use, a hose portion can be provided in the vacuum breaking tube 40 to facilitate the action of the pressing mechanism 4. When the vacuum is broken, the pressing mechanism 4 releases the pressure on the vacuum breaking tube 40, so that the sealed box is connected with the outside air.

[0058] The sealing box is equipped with an observation window 10 in the middle of each side including the lifting door 1.

[0059] The usage of the utility model is:

[0060] The motor 73 works, the synchronous belt drive assembly 72 starts to drive, and the lifting plate 70 moves upward or downward with the synchronous belt, and drives the lifting doors 1 on both sides to move upward or downward synchronously guided by the guide grooves 31 on the corresponding vertical beams 3 through the connecting assembly 8 to achieve opening and closing switching.

[0061] When the lifting door 1 is closed downward, the lifting door 1 will be guided by the inner curved portion 32 at the lower end of the guide groove 31, and will move downward toward the sealing box. The weight of the lifting door 1 and the guidance of the inner curved portion 32 can effectively ensure the reliability of the lifting door 1 fitting toward the sealing box.

[0062] The utility model has a compact and reasonable structure, effectively ensures the reliable fit between the lifting door and the sealing box, can be quickly opened and closed and ensures the sealing performance, and is particularly suitable for automated production.
