Description

Technical Field

[0001] This utility model relates to the field of food vacuum packaging, specifically to a vacuum packaging device for ready-to-eat food. Background Technology

[0002] Against the backdrop of rapid development in the food industry, ready-to-eat foods are highly favored by consumers due to their convenience. To extend the shelf life of ready-to-eat foods and maintain their taste and quality, vacuum packaging technology has been widely used. However, traditional vacuum packaging methods still have some problems in their use.

[0003] Existing vacuum packaging equipment may leave some small impurities and debris inside the packaging bag during the process of putting food into the bag. These foreign objects may be sucked into the vacuum pump during vacuuming, damaging the equipment and affecting the hygiene and quality of the food.

[0004] Furthermore, during the sealing process, the uneven surface of the packaging bag may cause localized incomplete sealing, affecting the airtightness and shelf life of the vacuum packaging.

[0005] Therefore, we have made improvements to this and proposed a vacuum packaging device for ready-to-eat foods. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. Through the use of the filtering mechanism, the connecting block and the fixed block are engaged with the connecting groove, and a fixed frame is set between them, with a filter screen installed inside the fixed frame.

[0034] To address the technical problems in the background section, the following vacuum packaging device for ready-to-eat foods is provided:

[0035] Combination Figure 1 - Figure 6As shown, the ready-to-eat food vacuum packaging device provided by this utility model includes a base box 1. A vacuum pump 2 is fixedly installed inside the base box 1, and a fixing block 3 is fixedly installed on the upper surface of the vacuum pump 2. An air extraction pipe 4 is provided on one side of the fixing block 3, and the air extraction pipe 4 is connected to the fixing block 3. A filter mechanism 5 is provided between the air extraction pipe 4 and the fixing block 3. An installation block 6 is fixedly installed on the upper surface of the base box 1, and a heating block 7 is fixedly installed inside the upper end of the installation block 6. A pressure frame 8 is provided on the upper side of the installation block 6, and the pressure frame 8 is slidably connected to the base box 1. Furthermore, a compaction mechanism 9 is provided inside the pressure frame 8; the filter mechanism 5 includes a connecting block 501, which is fixedly installed on one side surface of the suction pipe 4 and is connected to the suction pipe 4. A connecting groove 502 is provided on one side surface of the fixing block 3, and the connecting block 501 and the connecting groove 502 are engaged and connected. A fixing frame 503 is provided between the connecting block 501 and the connecting groove 502, and a filter screen 504 is fixedly installed inside the fixing frame 503. Rubber pads 505 are fixedly installed on both sides of the fixing frame 503.

[0036] In this embodiment: the base box 1 serves as the basic support structure for the entire device, with a vacuum pump 2 securely installed inside to provide power for the vacuuming operation. The fixing block 3 above the vacuum pump 2 provides connection and support. The suction pipe 4 is connected to the fixing block 3, and a filter mechanism 5 is provided between them. In the filter mechanism 5, the connecting block 501 fixed on one side of the suction pipe 4 engages with the connecting groove 502 on the fixing block 3. A fixing frame 503 is provided between them, and the filter screen 504 installed inside the fixing frame 503 can effectively intercept small impurities and debris extracted from the packaging bag during the vacuuming process. The rubber gaskets 505 on both sides enhance the sealing performance, prevent impurities from leaking out, and avoid impurities entering the vacuum pump 2 and damaging the equipment, thus ensuring the hygienic quality of the food packaging. A heating block 7 is provided inside the upper end of the mounting block 6 on the upper surface of the base box 1 for sealing and heating the packaging bag. The pressing frame 8, which is slidably connected to the bottom box 1 on the upper side of the mounting block 6, has a compaction mechanism 9 inside. When pressing down to seal, it can work with the heating block 7 to apply uniform and stable pressure to the sealed part of the packaging bag, ensuring the sealing effect and providing a reliable guarantee for the vacuum packaging of ready-to-eat foods.

[0037] In a preferred embodiment, the upper and lower surfaces of the connecting block 501 are provided with first sliding grooves 506, and a sliding plate 507 is slidably connected inside the first sliding groove 506. A pressing block 508 and a locking block 509 are fixedly installed on both sides of one side surface of the sliding plate 507. The upper and lower surfaces of the connecting groove 502 are provided with locking grooves 510, and the locking block 509 is locked to the locking groove 510. A first spring 511 is fixedly installed between the sliding plate 507 and the inner wall of the first sliding groove 506.

[0038] In this embodiment, first grooves 506 are carefully formed on the upper and lower surfaces of the connecting block 501, providing a precise track for the stable sliding of the sliding plate 507. The sliding plate 507, slidably connected inside the first groove 506, has a button 508 and a locking block 509 cleverly installed on both sides of one side surface. When installing the filter mechanism 5, simply press the button 508 to push the sliding plate 507 to compress the first spring 511, causing the locking block 509 to retract. After the connecting block 501 is engaged in the connecting groove 502 of the fixing block 3, releasing the button 508 causes the spring force generated by the resetting of the first spring 511 to push the sliding plate 507 back to its original position, thereby causing the locking block 509 to engage in the locking grooves 510 formed on the upper and lower surfaces of the connecting groove 502, achieving a secure engagement. This makes the installation and disassembly of the filter mechanism 5 simple and quick, facilitating the periodic cleaning or replacement of the filter screen 504 to maintain its good filtration performance.

[0039] In a preferred embodiment, the compaction mechanism 9 includes a second slide groove 901, which is formed inside the lower pressure frame 8. A movable plate 902 is slidably connected inside the second slide groove 901, and a compaction block 903 is fixedly installed on the lower surface of the movable plate 902. The compaction block 903 is made of silicone material.

[0040] In this embodiment: when vacuum packaging and sealing ready-to-eat foods, the lower pressure frame 8 presses down, and the moving plate 902 drives the compaction block 903 to move downwards accordingly, applying uniform and stable pressure to the sealing part of the packaging bag to ensure the sealing effect. It is particularly worth mentioning that the compaction block 903 is made of silicone material, which has the characteristics of being soft, elastic, and heat-resistant. Its soft texture prevents damage to the packaging bag when in contact with it, avoiding damage to the packaging bag due to excessive pressure and affecting the seal; its good elasticity allows it to better conform to the surface of the packaging bag, making the pressure distribution uniform and further improving the sealing quality; its heat-resistant properties allow it to cooperate with the heating block 7, maintaining stable performance during the heating and sealing process, without deforming or being damaged due to high temperatures, providing reliable protection for the vacuum packaging of ready-to-eat foods and effectively extending the shelf life of the food.

[0041] In a preferred embodiment, a second spring 904 is fixedly installed between the upper surface of the movable plate 902 and the inner wall of the second slide groove 901, and a fixing cylinder 905 is provided inside the second spring 904. A fixing rod 906 is slidably connected inside the fixing cylinder 905. The bottom end of the fixing cylinder 905 is fixedly installed on the upper surface of the movable plate 902, and the top end of the fixing rod 906 is fixedly installed on the top of the second slide groove 901.

[0042] In this embodiment, the second spring 904, fixedly installed between the upper surface of the moving plate 902 and the inner wall of the second slide groove 901, plays a crucial role in buffering and resetting during the packaging operation. When the pressing frame 8 is pressed down and the compaction block 903 applies pressure to the packaging bag for sealing, the second spring 904 is compressed as the moving plate 902 moves downward. The elastic force generated by the spring can evenly distribute the pressure, preventing damage to the packaging bag due to excessive instantaneous pressure. At the same time, it also allows the compaction block 903 to apply more continuous and stable pressure to the packaging bag, ensuring a sealing effect.

[0043] The combination structure of the fixed cylinder 905 and the fixed rod 906 inside the second spring 904 provides precise guidance for the extension and retraction of the second spring 904, effectively preventing the second spring 904 from deviating or twisting during the extension and retraction process, ensuring the normal operation and service life of the second spring 904, and thus improving the reliability and stability of the entire compaction mechanism 9.

[0044] In a preferred embodiment, hydraulic rods 10 are fixedly installed on both sides inside the bottom box 1, and the telescopic ends of the two hydraulic rods 10 are fixedly connected to both sides of the lower pressure frame 8.

[0045] In this embodiment: Hydraulic rods 10 are installed on both sides inside the bottom box 1, and their telescopic ends are connected to both sides of the lower pressure frame 8. During packaging, the hydraulic rods 10 retract, pushing the lower pressure frame 8 downward. The compaction mechanism 9, in conjunction with the heating block 7, completes the sealing, ensuring a uniform and firm seal. After sealing, the hydraulic rods 10 extend, causing the lower pressure frame 8 to rise and reset, allowing the food to be removed.

[0046] In a preferred embodiment, limit rods 11 are provided on both sides of the hydraulic rod 10, and the limit rods 11 are fixedly installed inside the bottom box 1. Limit grooves 12 are provided inside both sides of the pressure frame 8, and the limit rods 11 and the limit grooves 12 are slidably connected.

[0047] In this embodiment: when the hydraulic rod 10 drives the lower pressure frame 8 to move up and down, the limiting rod 11 slides synchronously in the limiting groove 12, which can effectively limit the movement trajectory of the lower pressure frame 8, prevent it from deviating, shaking or tilting during movement, and ensure that the lower pressure frame 8 always maintains a vertical and stable lifting state, which helps the compaction mechanism 9 to apply pressure to the sealing part of the packaging bag and ensure a uniform sealing effect.

[0048] Specifically, the working principle of this solution is as follows:

[0049] During use, the vacuum pump 2 inside the base box 1 provides the power to draw a vacuum. When the air extraction pipe 4 draws air, the filter mechanism 5 plays its role. The connecting block 501 is inserted into the connecting groove 502 of the fixing block 3. The filter screen 504 inside the fixing frame 503 intercepts impurities. The rubber gasket 505 enhances the sealing performance and prevents impurities from entering the vacuum pump 2.

[0050] The hydraulic rod 10 extends and retracts, causing the lower pressure frame 8 to move. The limiting rod 11 slides within the limiting groove 12, ensuring the lower pressure frame 8 rises and falls vertically and smoothly. When the lower pressure frame 8 presses down, the moving plate 902 of the compaction mechanism 9 moves the silicone compaction block 903 downward, applying pressure to the sealed area of ​​the packaging bag. The silicone is soft and does not damage the bag, has good elasticity to ensure uniform pressure, and is heat-resistant, working in conjunction with the heating block 7 for sealing. When the moving plate 902 moves downward, the second spring 904 is compressed. Its internal fixed cylinder 905 and fixed rod 906 guide the spring's extension and retraction, dispersing pressure and ensuring a sealing effect. After sealing, the hydraulic rod 10 extends, causing the lower pressure frame 8 to rise and reset. The entire device, through the coordinated work of its components, first evacuates the air from the packaging bag, then uses the compaction mechanism 9 and the heating block 7 to apply uniform and stable pressure and heat the sealed area of ​​the packaging bag, achieving efficient and reliable vacuum packaging and effectively extending the shelf life of ready-to-eat foods.

[0051] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0052] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
