Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging technology, specifically a vacuum packaging machine with a high-efficiency sterilization function. Background Technology

[0002] Vacuum packaging machines are packaging equipment widely used in the food, pharmaceutical, chemical, and electronics industries. Their main function is to remove air from the packaging bag to create a vacuum, thereby extending the shelf life of the product and maintaining its freshness and taste.

[0003] For example, Chinese Patent (Announcement No.: CN213083582U) discloses a vacuum packaging machine for food packaging, including a packaging box, a sealing cap, an ultraviolet germicidal lamp, an electric sealing device, a bracket, a slider, a rotating shaft, a limiting plate, a vacuum pump, a vacuum tube, and a control switch. This utility model, by adjusting the distance between two sets of sliders on the bracket, facilitates the fixing of the two ends of the food packaging bag placed in the placement slot, avoiding leakage or skewed sealing caused by instability of the food packaging bag during sealing, thus ensuring the quality of packaging. The rotating shaft can rotate the limiting plate to adjust its angle, making it suitable for packaging bags of different specifications and models, ensuring the stability of the packaging bag during placement, and making packaging more convenient. When the food bag is manually placed in for vacuuming and sealing, the ultraviolet germicidal lamp sterilizes the food to be packaged and maintains the hygiene inside the packaging machine, ensuring the food safety of consumption and making the packaging more hygienic.

[0026] 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.

[0027] Please see Figures 1 to 2 and Figures 5 to 6This embodiment of a vacuum packaging machine with high-efficiency sterilization function includes a housing 1, a vacuum chamber 2 extending through the housing 1 and fixed inside the housing 1, an input box 17 located inside the housing 1 is fixed at the bottom of the vacuum chamber 2, and a sealing assembly 7 for heat sealing is provided at the left end of the bottom wall of the vacuum chamber 2. The sealing assembly 7 consists of a heat insulation pad, a heating block, and a nickel-chromium strip. The bottom of the heat insulation pad is fixed to the left side of the bottom wall of the vacuum chamber 2, and a flow channel is formed between the sealing assembly 7 and the front and rear side walls of the inner cavity of the vacuum chamber 2, so that the gas in the inner cavity of the vacuum chamber 2 can flow, ensuring the stability and uniformity of the vacuum environment, thereby improving the efficiency of vacuuming and maintaining the vacuum state. A heating block is fixed at the top of the heat insulation pad, and a nickel-chromium strip is fixed at the top of the heating block. The heating block is fixed at the top of the heat insulation pad to ensure that heat can be effectively transferred to the sealed items during the heating process, and the nickel-chromium strip achieves the purpose of heat sealing of the items in the vacuum chamber 2 by conducting heat, thereby achieving an effective sealing function and ensuring the sealing and stability of the packaged items.

[0028] An air box 3 is fixed to the bottom wall of the inner cavity of the box 1. A vacuum pump 4 is fixed to the inner cavity of the air box 3. An air intake pipe 18 is fixedly connected to the air inlet of the vacuum pump 4, passing through the air box 3 and the input box 17 and extending into the vacuum box 2. Exhaust vents 5 are opened on both the left and right sides of the box 1. A filter plate is fixed in the exhaust vent 5, which can effectively prevent dust and other impurities in the outside air from entering the interior of the box 1 and keep the environment inside the box clean. Two bases 6 are fixed on the front and rear sides of the bottom of the box 1.

[0029] Telescopic components 8 are hinged to both the front and rear sides of the box body 1. The end of each telescopic component 8 away from the box body 1 is hinged to a fixed rod 9 located on both the front and rear sides of the box body 1 and hinged to the box body 1. There are two telescopic components 8. Each telescopic component 8 consists of a first stabilizing block, a second stabilizing block, and a telescopic part. The two first stabilizing blocks are fixed to the front and rear side walls of the box body 1, respectively. The two second stabilizing blocks are fixed to the opposite side of the two fixed rods 9, respectively. A telescopic part is hinged between the first stabilizing block and the second stabilizing block. The telescopic components 8 on the front and rear sides of the box body 1 can adjust their length as needed. At the same time, the telescopic part hinged between the first stabilizing block and the second stabilizing block can provide sufficient support.

[0030] Furthermore, the telescopic part consists of a piston, a cavity, a pressure box, and a movable rod. The bottom of the second stabilizing block is hinged to the top of the cavity. A pressure box is fixed to the outside of the cavity. A movable rod that penetrates into the inner cavity is hinged to the top of the first stabilizing block. A piston located inside the cavity is fixed to the top of the movable rod. Multiple air vents are provided on both the left and right sides of the cavity. Sealing sleeves are fixed at the connection between the movable rod and the cavity, and at the connection between the pressure box and the cavity. By filling the cavity with inert gas and utilizing the telescopic movement of the movable rod, the piston moves up and down within the cavity, thereby achieving gas compression and reflux. This balances the pressure inside the cavity and the pressure box, allowing the gas to be discharged into the pressure box through the air vents when pressed down and to flow back into the cavity through the air vents when pulled back up. At the same time, the use of sealing sleeves further ensures the sealing and reliability between the cavity and the pressure box. The overall telescopic function of the cavity is realized, and the stability and safety of the telescopic part are ensured.

[0031] A handrail 19 is fixed to the left side between the two fixed rods 9. A sterilization box 10 is fixed between the two fixed rods 9. A sealing ring is fixed to the bottom of the sterilization box 10. A sealing gasket matching the sealing ring is fixed to the top of the vacuum box 2, so that the sealing gasket at the top of the vacuum box 2 can fit tightly with the sealing ring, thereby ensuring the airtightness between the sterilization box 10 and the vacuum box 2. A sealing strip located inside the sealing ring and matching the nickel-chromium strip is fixed to the bottom of the sterilization box 10. The sealing strip at the bottom of the sterilization box 10 matches the nickel-chromium strip, further... The sealing effect is enhanced, effectively preventing the exchange of internal and external gases, ensuring the vacuum environment and sterilization effect inside the sterilization box 10, and improving the safety and reliability of the product. The top of the sterilization box 10 is fixed with a control panel 16. The left and right sides of the top wall of the inner cavity of the sterilization box 10 are respectively fixed with a first sterilization lamp 11 and a fixed box 12. The inner cavity of the fixed box 12 is provided with a moving mechanism 13. The bottom of the moving mechanism 13 is fixed with a second sterilization lamp 14 and a third sterilization lamp 15 that penetrate the fixed box 12 and extend into the sterilization box 10.

[0032] In this embodiment, when the item is placed in the vacuum chamber 2 and the bag opening is placed on the sealing assembly 7, the sealing ring and sealing gasket are completely closed by pressing down the handle 19, thereby creating a low vacuum environment inside the vacuum chamber 2. At this time, the vacuum pump 4 is started to perform air extraction, and multiple germicidal lamps are turned on. The first germicidal lamp 11 is turned on to irradiate the sealed area for sterilization. At the same time, the moving mechanism 13 will drive the second germicidal lamp 14 and the third germicidal lamp 15 to adjust their positions so as to perform targeted sterilization according to the size of the item. During this period, the sealing strip is pressed down and comes into close contact with the sealing assembly 7. Under the action of the sealing assembly 7, the heating and sealing step is completed, thereby effectively improving the sterilization efficiency and ensuring the high quality of the product.

[0033] Please see Figures 3 to 4To achieve efficient sterilization of items, the moving mechanism 13 in this embodiment includes a drive motor 1301 fixed to the back of the fixed box 12. The output shaft of the drive motor 1301 is fixed with a transmission rod 1302 that extends through the front of the fixed box 12 and is rotatably connected to the front side wall of the fixed box 12 via bearings. A drive wheel 1303 is fixed to the outer surface of the transmission rod 1302, and a driven wheel 1304 meshes with the right side of the drive wheel 1303. The front and rear side walls of the fixed box 12... A driven rod is rotatably connected to the fixed box 12 via a bearing. The driven wheel 1304 is fixed to the driven rod at its axis. The bottom of the driving wheel 1303 and the driven wheel 1304 are respectively engaged with a first sliding tooth 1305 and a second sliding tooth 1306. Sliding holes are provided on both the left and right sides of the fixed box 12 for the first sliding tooth 1305 and the second sliding tooth 1306 to slide. A second germicidal lamp 14 and a third germicidal lamp 15 that penetrate to the outside of the fixed box 12 are respectively fixed to the bottom of the first sliding tooth 1305 and the second sliding tooth 1306.

[0034] It should be noted that both the second germicidal lamp 14 and the third germicidal lamp 15 are composed of a reflector, a germicidal lamp, and a slider. The tops of the two sliders are fixed to the bottoms of the first sliding tooth 1305 and the second sliding tooth 1306, respectively. The bottom of the slider extends through to the outside of the fixed box 12 and is fixed with a germicidal lamp. The outer side of the germicidal lamp is threaded with a reflector. The first sliding tooth 1305 and the second sliding tooth 1306 are respectively fixed with a stop block on the side of the rear side wall and the front side wall of the inner cavity of the fixed box 12 to prevent the first sliding tooth 1305 and the second sliding tooth 1306 from sliding out of the fixed box 12, thereby ensuring safety and stability.

[0035] Furthermore, the bottom of the fixed box 12 is provided with a long through hole for the slider to slide, and the opposite sides of the two stops respectively penetrate into the front and rear side walls of the inner cavity of the fixed box 12. The inner walls of the front and rear sides of the fixed box 12 are provided with long sliding grooves for the stops to slide, and the second sliding tooth 1306 is located on the front side of the first sliding tooth 1305.

[0036] In addition, the back of the second sliding tooth 1306 is provided with a rear half groove that meshes with the driven wheel 1304, and the front of the first sliding tooth 1305 is provided with a front half groove that meshes with the driving wheel 1303. The driving wheel 1303 and the driven wheel 1304 are the same size. The driving wheel 1303 and the driven wheel 1304 need to drive the first sliding tooth 1305 and the second sliding tooth 1306, which are misaligned, to move. By opening a tooth groove in the shape of a half tooth, the misalignment of the first sliding tooth 1305 and the second sliding tooth 1306 during the meshing process with the corresponding gear can be prevented.

[0037] In this embodiment, after the drive motor 1301 is started, the drive transmission rod 1302 rotates, which in turn causes the drive wheel 1303 to rotate. This causes the drive wheel 1303 to mesh with the driven wheel 1304, driving the first sliding tooth 1305 and the second sliding tooth 1306 to move relative to or away from each other. This adjusts the position between the second germicidal lamp 14 and the third germicidal lamp 15 to accommodate items of different sizes, thereby improving the sterilization effect. Simultaneously, after the sealing strip is pressed down, it is heated and sealed by the sealing assembly 7, further improving sterilization efficiency and ensuring the high quality of the product.

[0038] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0039] The working principle of the above embodiments is as follows:

[0040] When the item is placed in the vacuum chamber 2, the bag opening is placed on the sealing assembly 7, and the handle 19 is pressed down, the sealing ring and sealing gasket are closed, creating a low vacuum state inside the vacuum chamber 2. The vacuum pump 4 is started to draw air into the vacuum chamber 2, and multiple germicidal lamps are turned on. The first germicidal lamp 11 sterilizes the sealed area. The drive motor 1301 starts and drives the transmission rod 1302 to rotate, causing the drive wheel 1303 to rotate. The drive wheel 1303 then meshes with the driven wheel 1304, thereby engaging the first sliding tooth 1305 and the second sliding tooth 1306 to move relative to or away from each other. This allows for adjustment of the position between the second germicidal lamp 14 and the third germicidal lamp 15, enabling targeted sterilization based on the size of the item. At the same time, the sealing strip is pressed down and tightened, and the sealing assembly 7 heats and seals the item, improving sterilization efficiency and ensuring high product quality.
