[0002] Food packaging is an integral part of food products and a major engineering process in the food industry. It protects food from biological, chemical, and physical damage during its journey from the factory to the consumer. It also helps maintain the food's stable quality, facilitates consumption, and enhances the food's appearance to attract consumers. Beyond material costs, food packaging is an integral part of the food manufacturing systems engineering. The versatility of food packaging processes also gives it a relatively independent system, with vacuum sealing machines required for the sealing of food packaging bags.

[0003] Existing vacuum sealing machines mainly seal packaging bags by using a cover plate, then starting a vacuum pump to evacuate the packaging bag inside the cover plate, and then heating it with electricity to fuse and seal the bag opening to ensure airtightness. During the sealing process, the cover plate needs to be manually rotated to fit against the top of the sealing machine's operating table. There will be gaps at the fit between the cover plate and the sealing machine, allowing external air to enter the inside of the cover plate, thus affecting the vacuum sealing operation inside the cover plate. Utility Model Content

The reinforcing part is disposed on both sides of the cover plate. The reinforcing part has a fixing frame connected to both sides of the cover plate. A spring is connected inside the fixing frame, and a fixing block is connected to the other end of the spring. The fixing block is slidably connected to the fixing frame, and the fixing block is embedded in the limiting groove on the outer side of the packaging machine body. The horizontal movement of the fixing block inside the fixing frame causes the spring to deform.

[0006] By adopting the above technical solution, during the process of placing the cover plate above the main body of the packaging machine, the fixing block will fit against the outer wall of the main body of the packaging machine and move into the fixed frame, causing the spring to deform. After the cover plate is placed, the spring will restore its deformation and push the fixing block to move in the limiting groove of the main body of the packaging machine, causing the cover plate to move downward, thereby improving the sealing performance after the cover plate is placed.

[0007] Preferably, the reinforcing part further includes a connecting plate hinged above the fixing block, and a pull plate is hinged above the connecting plate.

[0010] By adopting the above technical solution, the fixed block will move downwards due to the influence of the inclined plane during horizontal movement, which will drive the entire fixed frame to move downwards.

[0011] Preferably, the bottom of the fixing block has a smooth curved shape, and the fixing block is made of stainless steel.

[0012] By adopting the above technical solution, after the fixing block is attached to the outer wall of the packaging machine body, it will move inward to the inside of the fixing frame due to the influence of the curved surface, causing the spring to deform.

[0015] Preferably, the sliding rod is a cylinder, and the sliding rod passes through the hole formed in the center of the spring.

[0016] By adopting the above technical solution, the spring can be limited by the sliding rod, reducing the occurrence of spring deformation and misalignment.

[0017] Preferably, a limiting block is fixedly connected to the bottom of the pull plate, and the limiting block is slidably connected to the cover plate.

[0018] By adopting the above technical solution, the stability of the pull plate during vertical movement can be improved by using the limiting block, and the limiting block can drive the cover plate to move during vertical movement.

[0019] Preferably, a sealing ring is provided at the bottom of the cover plate, and the sealing ring at the bottom of the cover plate is in close contact with the main operating table of the packaging machine.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0033] Example 1

[0034] Please see Figure 1-6 This embodiment provides a technical solution: a packaging device with dual independent vacuum chambers, including a packaging machine body 1, a cover plate 2, and a reinforcing part 3. The outer wall of the packaging machine body 1 has a limiting groove. The packaging machine body 1 starts a vacuum pump and draws out the air in the bag through the air circuit system to reach a preset vacuum degree. At this time, the oxygen in the bag is removed, inhibiting the growth of microorganisms. After the vacuum is completed, the heat sealing device is energized and heated, and the bag mouth is fused and sealed by pressurization to ensure airtightness. Air is introduced into the vacuum chamber to release the negative pressure, and the cover is opened to take out the packaged items. The above is the existing disclosed technology. The cover plate 2 is connected to the top of the packaging machine body 1. The cover plate 2 is connected to the outer shell of the packaging machine body 1 through four sets of connecting rods, and the cover plate 2 is connected to the vacuum pump inside the packaging machine body 1 through a connecting pipe.

[0035] The reinforcing part 3 is disposed on both sides of the cover plate 2. The reinforcing part 3 has a fixing frame 301 connected to both sides of the cover plate 2. The fixing frame 301 is connected to the cover plate 2 by multiple sets of bolts to ensure the stability of the fixing frame 301 after installation. A spring 302 is connected inside the fixing frame 301. The inner wall of the fixing frame 301 is connected to one end of the spring 302 by a buckle. The spring 302 is as follows: Figure 3 The diagram shows the compressed deformation state, with the other end of the spring 302 connected to a fixing block 303. The spring 302 is connected to the fixing block 303 via a buckle. During the recovery deformation process, the spring 302 can push the fixing block 303 to move horizontally. The fixing block 303 is slidably connected to the fixing frame 301. One end of the fixing block 303 passes through the fixing frame 301, and the fixing block 303 is embedded in the limiting groove on the outside of the packaging machine body 1. By embedding the fixing block 303 into the limiting groove of the packaging machine body 1, the sealing performance of the cover plate 2 after it fits against the top of the packaging machine body 1 is improved. The horizontal movement of the fixing block 303 inside the fixing frame 301 causes the spring 302 to deform.

[0036] Example 2

[0037] Please see Figure 1-6The reinforcing part 3 also includes a connecting plate 305 hinged above the fixing block 303. Rotation of the connecting plate 305 can cause the fixing block 303 to move horizontally. A pull plate 306 is hinged above the connecting plate 305. Vertical movement of the pull plate 306 can cause the connecting plate 305 to rotate. Pulling the pull plate 306 can quickly release the fixing block 303, making it convenient for workers to open the cover plate 2 to seal the packaging bag. The packaging machine body 1 has a beveled groove inside, and the fixing block... 303 is located on one side of the main body 1 of the packaging machine and has a sloping shape. The sloping side of the fixing block 303 is in contact with the sloping side of the limiting groove of the main body 1 of the packaging machine. During horizontal movement, the fixing block 303 will move downward due to the influence of the sloping surface, which will drive the fixing frame 301 to move downward as a whole. The bottom of the fixing block 303 has a smooth curved shape and is made of stainless steel. After the fixing block 303 is in contact with the outer wall of the main body 1 of the packaging machine, it will move inward towards the fixing frame 301 due to the influence of the curved surface, causing the spring 302 to deform.

[0038] A sliding rod 304 is fixedly connected to the inner wall of the fixed frame 301, and the sliding rod 304 is slidably connected to the fixed block 303. The sliding rod 304 can limit the fixed block 303 to prevent it from shifting during horizontal movement. The sliding rod 304 is cylindrical and passes through the hole formed in the center of the spring 302. The sliding rod 304 can limit the spring 302 to reduce the occurrence of deformation and misalignment of the spring 302. The bottom of the pull plate 306 is fixedly connected to... A limiting block 307 is connected and slidably connected to the cover plate 2. The limiting block 307 can improve the stability of the pull plate 306 during vertical movement. The limiting block 307 also allows the pull plate 306 to drive the cover plate 2 to move during vertical movement. A sealing ring is provided at the bottom of the cover plate 2, and the sealing ring at the bottom of the cover plate 2 is tightly fitted with the operating table of the packaging machine body 1. The sealing ring will deform after the cover plate 2 is fitted with the packaging machine body 1, thereby improving the airtightness of the cover plate 2.

[0039] Working principle: First, when it is necessary to release the cover plate 2, manually pull the pull plate 306 upward. Since the pull plate 306 is hinged to the connecting plate 305, and the connecting plate 305 is hinged to the fixing block 303, and the fixing block 303 is slidably connected to the sliding rod 304, the pull plate 306 will drive the fixing block 303 to move horizontally under the action of the connecting plate 305 during the upward movement. The fixing block 303 gradually retracts into the fixing frame 301 during the horizontal movement, releasing the cover plate 2. During the movement of the pull plate 306, it will also drive the limiting block 307 to move downward. The limiting block 307 will move upward and fit against the inner wall of the groove above the cover plate 2. Therefore, after the pull plate 306 moves upward to a certain height, it will also drive the cover plate 2 to move, improving the efficiency of the cover plate 2 flipping and switching.

[0040] Secondly, when it is necessary to fix the cover plate 2, manually push the cover plate 2 to move diagonally downward. During the movement of the cover plate 2, the curved surface at the bottom of the fixing block 303 will fit against the outer wall of the packaging machine body 1. Under the influence of the curved surface shape, the fixing block 303 will be stored inside the fixing frame 301. During the storage process of the fixing block 303, the spring 302 will deform. When the fixing block 303 moves downward to the limiting groove point of the packaging machine body 1, the spring 302 will gradually restore its deformation and push the fixing block 303 to move horizontally and embed into the limiting groove. Since the inner wall of the inclined groove is inclined, the fixing block 303 will drive the fixing frame 301 to move downward as a whole during the embedding process. The movement of the fixing frame 301 will drive the cover plate 2 to move. The movement of the cover plate 2 will cause the sealing ring at the bottom to deform, improving the sealing performance of the cover plate 2 after it is closed.
