Description

Technical Field

[0001] This utility model relates to the field of vacuum equipment technology, specifically a vacuum device for food production and processing. Background Technology

[0002] Vacuum packaging, also known as depressurized packaging, involves removing all the air from the packaging container and sealing it to maintain a high depressurization state inside the bag. The scarcity of air is equivalent to a low-oxygen effect, which eliminates the conditions for microorganisms to survive, thereby ensuring the freshness of the fruit and preventing disease and rot.

[0003] Utility model patent application number: CN202121655045.4 discloses a vacuuming device for food processing, relating to the field of vacuuming technology. The device includes a cabinet with an upward-opening sealing cover on top. Multiple vacuum machines are installed on the upper surface of the upward-opening sealing cover. Multiple vacuuming slots are installed inside the cabinet. The vacuum tubes of the vacuum machines pass through the upward-opening sealing cover and extend into the vacuuming slots. Each vacuuming slot is equipped with a heating element, and each heating element is equipped with a pressing mechanism that cooperates with the upward-opening sealing cover. Each vacuuming slot is equipped with a sliding plate that is adapted to it. The sliding plate is slidably connected to the inner side wall of the vacuuming slot. A telescopic component is installed at the bottom of the sliding plate, and the telescopic shaft of the telescopic component is connected to the sliding plate.

[0004] The aforementioned patent uses an upward-opening sealing cap to press the clamping mechanism downwards during the closing process, causing the clamping mechanism to come into contact with the heating element. The heating element heat-seals the opening of the packaging bag to be vacuumed, and the vacuum machine removes the air from the packaging bag. Since the heating element is directly installed under the pressure bar in an exposed state, users are prone to touching the heating element and causing injury when placing the packaging bag between the heating element and the pressure bar. Furthermore, the entire cycle from the sealing cap contacting the packaging bag to complete clamping and the formal completion of the vacuuming operation is relatively long. During this waiting period, operators cannot perform pre-processing of the next batch of packaging bags and are in an idle state, reducing overall work efficiency. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please refer to Figures 1 to 7 This utility model provides a technical solution: a vacuuming device for food production and processing, including a cabinet 1, with two vacuuming slots 2 opened on the top of the cabinet 1, and a sealing cover 3 that cooperates with the vacuuming slots 2 on the top of the cabinet 1. Two connecting frames 11 are provided between the two sides of the sealing cover 3 and the two sides of the cabinet 1. A fixing frame 4 is fixedly connected to the bottom wall of each of the two vacuuming slots 2. A heating element 5 is slidably fitted inside the fixing frame 4. A pressure rod 6 is provided at the opening at the top of the fixing frame 4. A connecting component 7 is provided between the pressure rod 6 and the heating element 5. An installation chamber 8 is provided inside the cabinet 1. A vacuum machine 9 is fixedly installed on the bottom wall of the installation chamber 8. Two vacuum tubes 10 are fixedly connected to the air intake of the vacuum machine 9. The air inlets of the two vacuum tubes 10 respectively penetrate into the two vacuuming slots 2.

[0027] In this embodiment, an operation panel 12 is fixedly installed on the outside of the cabinet 1. Sealing grooves 13 are provided around the openings above the two vacuum tanks 2. A sealing strip 14 that mates with the sealing groove 13 is fixedly connected to the bottom of the sealing cover 3. Two first connecting posts 21 are fixedly connected to both sides of the sealing cover 3. Second connecting posts 22 are fixedly connected to the outer sides of both side panels in the middle of the cabinet 1. The upper end of the connecting frame 11 is rotatably engaged with the first connecting post 21, and the lower end of the connecting frame 11 is rotatably engaged with the second connecting post 22. Four connecting frames 11... The components are arranged in pairs parallel to each other on both sides of the cabinet 1 and the sealing cover 3, allowing the sealing cover 3 to be adjusted above two different vacuum slots 2. The sealing cover 3 has a storage slot 16 extending to the outside, and a baffle plate 17 is slidably fitted inside the storage slot 16. An insert 18 is fixedly connected to the bottom of the baffle plate 17 away from the sealing cover 3. The insert 18 cooperates with the sealing slot 13. A fixing bolt 19 is threaded on the top of the sealing cover 3, extending into the storage slot 16 and overlapping with the baffle plate 17. Two handles 20 are fixedly connected to the top of the sealing cover 3.

[0028] Specifically, the sealing cover 3 is lifted by the handle 20. Using the rotational engagement of the connecting frame 11 with the first connecting column 21 and the second connecting column 22, the sealing cover 3 is moved to the side of one of the vacuum chambers 2. The food packaging bag to be processed is placed above the fixing frame 4 inside the vacuum chamber 2, so that the bag opening is between the pressure rod 6 and the heating element 5. Then, the sealing cover 3 is lowered, and its bottom sealing strip 14 is embedded into the sealing groove 13 at the opening of the vacuum chamber 2 to complete the initial seal. The vacuum machine 9 is started via the operation panel 12, and the vacuum machine 9 evacuates the inside of the vacuum chamber 2 through the vacuum tube 10. After evacuation, the heating element 5 is energized and heats up, heat-sealing the compressed packaging bag opening. The sealing cover 3 can be switched to another vacuum chamber 2 via the connecting frame 11, and the above operation is repeated. Simultaneously, the previous vacuum chamber 2 is used for the pre-processing of the next batch of packaging bags.

[0029] In this embodiment, the connecting assembly 7 includes upright blocks 701 fixedly connected to both ends of the pressure rod 6. The bottom walls of the two vacuum grooves 2 are provided with downward-facing sliding grooves 702 on both sides of the fixing frame 4. The upright blocks 701 are slidably fitted within the sliding grooves 702. The slot of the fixing frame 4 extends downwards and communicates with the sliding grooves 702. Two pressure blocks 15 that cooperate with the pressure rod 6 are fixedly connected to the bottom of the sealing cover 3. Fixing blocks 705 are fixedly connected to the outer sides of the upright blocks 701 on both sides. A spring 706 is fixedly connected between the bottom of the fixing block 705 and the bottom wall of the vacuum groove 2. A fixing post 703 is fixedly connected between the inner wall of the slot of the fixing frame 4 and the inner wall of the sliding groove 702. A connecting strip 7 is rotatably fitted around the periphery of the fixing post 703. 04. The heating element 5 is fixedly connected to both sides with a first connecting shaft 707, and the bottom of the two upright blocks 701 is fixedly connected to a second connecting shaft 708. The connecting strip 704 has a strip-shaped groove 709 on both sides. The first connecting shaft 707 rotates and slides in the lower strip-shaped groove 709, and the second connecting shaft 708 rotates and slides in the upper strip-shaped groove 709. When the sealing cover 3 is closed, the pressure block 15 moves downward and abuts against the pressure rod 6. As the pressure rod 6 moves downward, it drives the heating element 5 to move upward through the connecting strip 704, so that the food packaging bag is located between the pressure rod 6 and the heating element 5 and heat-sealed. When the sealing cover 3 is opened, the heating element 5 retracts into the fixing frame 4 by the force of the spring 706.

[0030] Specifically, when the sealing cap 3 is closed, the bottom pressure block 15 abuts against the pressure rod 6 and pushes it downward. The upright blocks 701 at both ends of the pressure rod 6 slide along the slide groove 702, causing the fixing block 705 to compress the spring 706. At the same time, the second connecting shaft 708 at the bottom of the upright block 701 pushes the first connecting shaft 707 on both sides of the heating element 5 through the connecting strip 704 (rotating around the fixing column 703), so that the heating element 5 moves upward from inside the fixing frame 4 and cooperates with the pressure rod 6 to press the opening of the packaging bag. After the heat sealing is completed, the sealing cap 3 is lifted, the spring 706 returns to its original position and pushes the fixing block 705, the upright block 701 and the pressure rod 6 upward. Through the reverse linkage of the connecting strip 704, the heating element 5 retracts into the fixing frame 4.

[0031] When using the device, the operator lifts the sealing cover 3 using the handle 20. Utilizing the rotational cooperation of the connecting frame 11 with the first connecting column 21 and the second connecting column 22, the sealing cover 3 is moved to the side of one of the vacuum chambers 2. The food packaging bag to be processed is placed above the fixed frame 4 within the vacuum chamber 2, so that the bag opening is between the pressure rod 6 and the heating element 5. Then, the sealing cover 3 is lowered, and its bottom sealing strip 14 embeds into the sealing groove 13 at the opening of the vacuum chamber 2 to complete the initial seal. During the closing process of the sealing cover 3, the pressure block 15 presses down on the pressure rod 6, causing the upright block 701 to slide along the slide groove 702 and compress the spring 706. Simultaneously, the connecting strip 704 drives the heating element 5 to move upward from the fixed frame 4, cooperating with the pressure rod 6 to press... Tighten the opening of the packaging bag; start the vacuum machine 9 through the operation panel 12. The vacuum machine 9 evacuates the vacuum tank 2 through the vacuum tube 10. After the vacuuming is completed, the heating element 5 is energized to heat seal the opening of the packaging bag; after the heat sealing is completed, lift the sealing cover 3. The spring 706 returns to its original position, causing the heating element 5 to retract into the fixed frame 4. Take out the packaged food. Then switch the sealing cover 3 to another vacuum tank 2 and repeat the operation. At the same time, the previous vacuum tank 2 can be pre-treated for the next batch of packaging bags. After use, the baffle 17 in the storage slot 16 can be slid to allow the insert 18 to be inserted into the sealing slot 13. Then fix the baffle 17 with the fixing bolt 19 to cover the vacuum tank 2 that does not have a sealing cover 3, thus providing protection.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
