Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a food vacuum packaging device. Background Technology

[0002] In the food processing and storage field, vacuum packaging technology is widely used because it can effectively extend the shelf life of food and prevent food oxidation and spoilage. Existing food vacuum packaging equipment usually uses a vacuum pump to evacuate the vacuum chamber to achieve vacuum sealing of food. However, traditional vacuum packaging equipment has many problems in the evacuation process: on the one hand, the opening and closing of the evacuation channel is mostly controlled by manual valves or complex pneumatic valves, which are inconvenient to operate, have slow response speed, and insufficient vacuum control precision, affecting the vacuuming efficiency and the stability of packaging quality; on the other hand, most devices only have a single evacuation port and a corresponding filter component, which limits the evacuation rate, and the single filter component is prone to rapid failure due to excessive load, requiring frequent cleaning or replacement. Especially when processing foods containing soup or crumbs, liquids and impurities can easily break through the filter and enter subsequent equipment, increasing maintenance costs and the risk of equipment failure.

[0003] Therefore, we propose a food vacuum packaging device. Utility Model Content

[0004] The main objective of this invention is to provide a food vacuum packaging device that addresses the problems of inconvenient control of the air extraction channel, slow response, insufficient vacuum precision, low extraction rate, easy failure of the filter component, and the entry of liquid and impurities into subsequent equipment caused by a single air extraction hole and filter component in traditional vacuum packaging devices. This invention improves vacuum efficiency, vacuum control precision, and packaging quality stability, while also enhancing filtration effect, extending equipment lifespan, and reducing maintenance costs. It can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A food vacuum packaging device includes a body with a vacuum chamber inside. Two suction holes are provided on the rear side wall of the vacuum chamber. Two suction pipes are provided inside the body and connected to the two suction holes. An air inlet pipe is connected to the rear end of each suction pipe. A rotating shaft is rotatably connected to the top end of each suction pipe. Two valve plates are fixedly connected to the bottom ends of the two rotating shafts, passing through the two suction pipes respectively. A motor is fixedly installed on the outer wall of the top end of each suction pipe. The output shaft of the motor is fixedly connected to the top end of the rotating shaft. A filter mechanism is slidably connected to the front part of each suction pipe.

[0007] By adopting the above technical solution, when it is necessary to vacuum the food in the vacuum chamber, the equipment is started through the control panel. The motor drives the rotating shaft to rotate, which in turn drives the valve plate to rotate to the open state, so that the suction pipe is connected to the suction port. At this time, the external vacuum pump evacuates the vacuum chamber through the air inlet pipe and the suction pipe, and then through the suction port. When the vacuum chamber reaches the set vacuum level, the motor drives the valve plate to rotate to the closed state again, stopping the evacuation, thus completing the vacuuming process.

[0008] Furthermore, the filtration mechanism includes filter cylinders that are slidably connected to two suction pipes respectively. A pull rod is fixedly connected to the inner wall of the front end of the filter cylinder, and a pull plate is fixedly connected to the front end of the pull rod. An absorbent sponge is fixedly installed on the inner circumference of the filter cylinder.

[0009] By adopting the above technical solution, when the vacuum packaging device performs air extraction, the gas enters the extraction pipe from the vacuum chamber through the extraction port. It first passes through the filtration mechanism, where the liquid-absorbing sponge can absorb small amounts of liquid mixed in the gas, such as soup seeping out of food, while the filter screen can filter out solid impurities in the gas, such as food scraps. This effectively prevents liquids and impurities from entering the subsequent extraction pipe and vacuum pump, ensuring the normal operation of the equipment. When it is necessary to clean or replace the filtration mechanism, the user can pull the pull plate and pull the pull rod to pull the filter screen out of the extraction pipe, which is convenient to operate.

[0010] Furthermore, a filter screen plate is fixedly installed at the front end of each of the two air extraction holes. The aperture of the filter screen plate is larger than that of the filter screen cylinder. A sealing strip is fixedly connected to each of the two valve plates.

[0011] By adopting the above technical solution, when the vacuum chamber is evacuated, the filter screen plate at the front end of the evacuation port will first perform preliminary filtration of the incoming gas, intercepting larger particles of impurities such as large food fragments, preventing them from entering the evacuation pipe and clogging the pipe. Since its aperture is larger than that of the filter screen cylinder, it can form a multi-stage filtration with the filter screen cylinder, improving the filtration effect. At the same time, the sealing strip on the valve plate can tightly fit the inner wall of the evacuation pipe when the valve plate is closed, enhancing the sealing performance of the valve plate, avoiding air leakage during the evacuation process, and ensuring that the vacuum chamber can reach the required vacuum level.

[0012] Furthermore, a sealing cover is hinged to the rear side of the machine body, a sealing ring is fixedly connected to the inner wall of the sealing cover, and a high-temperature resistant silicone strip is fixedly connected to the inner wall of the sealing cover, with the high-temperature resistant silicone strip located inside the sealing ring.

[0013] By adopting the above technical solution, when food needs to be vacuum packaged, after the food is placed in the vacuum chamber and the sealing cover is closed, the sealing ring on the inner wall of the sealing cover will fit tightly against the edge of the machine body, playing a first-level sealing role to prevent outside air from entering the vacuum chamber. The high-temperature resistant silicone strip located inside the sealing ring will further enhance the sealing effect. At the same time, in the subsequent sealing process, due to its high-temperature resistant properties, it can remain stable when the sealing strip is heated, avoiding damage due to high temperature, and ensuring that the sealing performance between the sealing cover and the vacuum chamber is always good.

[0014] Furthermore, a sealing strip that works in conjunction with a high-temperature resistant silicone strip is fixedly connected to the inner wall of the bottom end of the vacuum chamber.

[0015] By adopting the above technical solution, after the vacuuming operation is completed in the vacuum chamber, the food packaging bag needs to be sealed. At this time, the high-temperature resistant silicone strip on the sealing cap will cooperate with the sealing strip on the inner wall of the bottom of the vacuum chamber to press the sealed part of the packaging bag tightly between the two. Subsequently, the sealing strip is energized and heated to heat the sealed part of the packaging bag, causing the packaging material to melt and stick together, thus completing the sealing operation. The high-temperature resistant silicone strip can not only ensure uniform pressure during the pressurization process, but also withstand the high temperature during sealing, ensuring that the seal is firm and tight.

[0016] Furthermore, the front end of the machine body is equipped with a control panel and a vacuum gauge, and the bottom of the machine body is equipped with support legs at the four corners.

[0017] By adopting the above technical solution, users can set various parameters of the vacuum packaging device through the control panel at the front of the machine, such as vacuuming time, sealing temperature, and sealing time. The operation is simple and intuitive. During the operation of the equipment, the vacuum gauge can display the vacuum level in the vacuum chamber in real time, making it convenient for users to observe and monitor the progress and effect of vacuuming. At the same time, the support legs at the four corners of the bottom of the machine can make the device stand stably on the ground or workbench, preventing the equipment from shaking or shifting during operation and ensuring the safety and stability of operation.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This utility model provides a food vacuum packaging device, which adopts a design with two suction holes and two suction pipes. Compared with the traditional single suction hole structure, it significantly increases the total cross-sectional area of ​​the suction channel, accelerates the exhaust speed of the gas inside the vacuum chamber, greatly shortens the vacuuming time, and improves the overall operating efficiency. At the same time, each suction pipe is controlled by a motor-driven valve plate. The motor responds quickly and controls precisely, and can immediately close the valve plate when the vacuum chamber reaches the set vacuum level, avoiding over-vacuuming or under-vacuuming, ensuring the consistency of vacuum control, and guaranteeing the quality of food packaging.

[0020] (2) This utility model provides a food vacuum packaging device, in which two independent filtration mechanisms are set in the two suction pipes, forming a one-to-one filtration path with the two suction holes. When gas enters the suction pipe from the vacuum chamber through the suction hole, the liquid-absorbing sponge and filter screen in each filtration mechanism can intercept liquid and solid impurities in the corresponding path respectively, thus dispersing the filtration load and improving the overall filtration efficiency and effect. In addition, the independent filtration mechanism design allows a single filtration component to be extracted for cleaning or replacement without affecting the temporary use of the other suction pipe, reducing equipment downtime for maintenance. This structure effectively prevents liquid and impurities from entering the subsequent suction pipe and vacuum pump, reducing the probability of equipment failure and maintenance costs, and significantly extending the service life of the equipment.

[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] To prevent problems in traditional vacuum packaging equipment, such as inconvenient control of the air extraction channel, slow response, insufficient vacuum accuracy, and low extraction rate, easy filter failure, and the entry of liquids and impurities into subsequent equipment due to a single extraction port and filter components, this device aims to improve vacuum efficiency, vacuum control accuracy, and packaging quality stability, while also enhancing filtration effect, extending equipment lifespan, and reducing maintenance costs. Figure 1 , Figure 2 , Figure 3As shown, a food vacuum packaging device includes a body 1, a vacuum chamber 2 inside the body 1, two air extraction holes 3 on the rear side wall of the vacuum chamber 2, two air extraction pipes 4 inside the body 1, and the two air extraction pipes 4 are connected to the two air extraction holes 3. The rear ends of the two air extraction pipes 4 are connected to air inlet pipes 5. The top ends of the two air extraction pipes 4 are rotatably connected to rotating shafts 6. The bottom ends of the two rotating shafts 6 pass through the two air extraction pipes 4 and are fixedly connected to two valve plates 7. Motors 8 are fixedly installed on the outer walls of the top ends of the two air extraction pipes 4. The output shaft of the motor 8 is fixedly connected to the top end of the rotating shaft 6. Filter mechanisms 21 are slidably connected to the front of the two air extraction pipes 4.

[0027] When it is necessary to vacuum the food in the vacuum chamber 2, the device is started through the control panel 18. The motor 8 drives the rotating shaft 6 to rotate, which in turn drives the valve plate 7 to rotate to the open state, so that the suction pipe 4 is connected to the suction port 3. At this time, the external vacuum pump evacuates the inside of the vacuum chamber 2 through the air inlet pipe 5 and the suction pipe 4, and through the suction port 3. When the vacuum chamber 2 reaches the set vacuum level, the motor 8 drives the valve plate 7 to rotate to the closed state again, stopping the evacuation, thus completing the vacuuming process.

[0028] For example, such as Figure 3 As shown, the present invention also includes a filter mechanism 21 comprising a filter cylinder 9 slidably connected to two suction pipes 4 respectively, a pull rod 11 fixedly connected to the inner wall of the front end of the filter cylinder 9, a pull plate 12 fixedly connected to the front end of the pull rod 11, and an absorbent sponge 10 fixedly installed on the inner circumference of the filter cylinder 9.

[0029] When the vacuum packaging device is in use, the gas enters the suction pipe 4 from the vacuum chamber 2 through the suction port 3. It first passes through the filter mechanism 21, where the liquid-absorbing sponge 10 can absorb small amounts of liquid mixed in the gas, such as soup seeping out of food, while the filter screen 9 filters out solid impurities in the gas, such as food scraps. This effectively prevents liquids and impurities from entering the subsequent suction pipe and vacuum pump, ensuring the normal operation of the equipment. When the filter mechanism 21 needs to be cleaned or replaced, the user can pull the pull plate 12 to drive the pull rod 11 to pull the filter screen 9 out of the suction pipe 4. The operation is convenient.

[0030] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes a filter screen plate 13 fixedly installed at the front end of each of the two air extraction holes 3, the aperture of the filter screen plate 13 being larger than the aperture of the filter screen cylinder 9, and a sealing strip fixedly connected to each of the two valve plates 7.

[0031] During use, when the vacuum chamber 2 is evacuated, the filter plate 13 at the front end of the evacuation port 3 will first perform preliminary filtration on the incoming gas, intercepting larger particles of impurities such as large food fragments, preventing them from entering the evacuation pipe 4 and clogging the pipe. Since its aperture is larger than that of the filter cylinder 9, it can form a multi-stage filtration with the filter cylinder 9, improving the filtration effect. At the same time, when the valve plate 7 is closed, the sealing strip on the valve plate 7 can fit tightly against the inner wall of the evacuation pipe 4, enhancing the sealing performance of the valve plate 7, avoiding air leakage during the evacuation process, and ensuring that the vacuum chamber 2 can reach the required vacuum level.

[0032] For example, such as Figure 1 As shown, the present invention also includes a sealing cover 14 hinged to the rear side of the body 1, a sealing ring 16 fixedly connected to the inner wall of the sealing cover 14, and a high-temperature resistant silicone strip 15 fixedly connected to the inner wall of the sealing cover 14, with the high-temperature resistant silicone strip 15 located inside the sealing ring 16.

[0033] When vacuum packaging food is required, the food is placed in the vacuum chamber 2 and the sealing cover 14 is closed. At this time, the sealing ring 16 on the inner wall of the sealing cover 14 will fit tightly against the edge of the body 1, playing a first-level sealing role to prevent outside air from entering the vacuum chamber 2. The high-temperature resistant silicone strip 15 located inside the sealing ring 16 will further enhance the sealing effect. At the same time, in the subsequent sealing process, due to its high-temperature resistant properties, it can remain stable when the sealing strip 17 is heated, avoiding damage due to high temperature, and ensuring that the sealing cover 14 and the vacuum chamber 2 always have good sealing performance.

[0034] For example, such as Figure 1 As shown, the present invention also includes a sealing strip 17 fixedly connected to the bottom inner wall of the vacuum chamber 2 for use in conjunction with the high-temperature resistant silicone strip 15.

[0035] During use, after the vacuuming operation is completed in the vacuum chamber 2, the food packaging bag needs to be sealed. At this time, the high-temperature resistant silicone strip 15 on the sealing cap 14 will cooperate with the sealing strip 17 on the inner wall of the bottom of the vacuum chamber 2 to press the sealed part of the packaging bag tightly between the two. Then, the sealing strip 17 is energized and heated to heat the sealed part of the packaging bag, so that the packaging material melts and sticks together to complete the sealing operation. The high-temperature resistant silicone strip 15 can not only ensure uniform pressure during the pressurization process, but also withstand the high temperature during sealing to ensure that the seal is firm and tight.

[0036] For example, such as Figure 1 As shown, the present invention also includes a control panel 18 and a vacuum gauge 19 respectively provided at the front end of the body 1, and support legs 20 provided at the four corners of the bottom end of the body 1.

[0037] During use, users can set various parameters of the vacuum packaging device, such as vacuuming time, sealing temperature, and sealing time, through the control panel 18 at the front of the machine body 1. The operation is simple and intuitive. During the operation of the equipment, the vacuum gauge 19 can display the vacuum level in the vacuum chamber 2 in real time, which makes it convenient for users to observe and monitor the progress and effect of vacuuming. At the same time, the support legs 20 at the four corners of the bottom of the machine body 1 can make the device stand stably on the ground or workbench, preventing the equipment from shaking or shifting during operation and ensuring the safety and stability of operation.

[0038] It should be noted that this utility model is a food vacuum packaging device. First, the device is placed stably by the support legs 20 at the four corners of the bottom. After connecting the power, the sealing cover 14 is opened, and the food to be packaged is placed into the vacuum chamber 2, so that the open end of the packaging bag is aligned with the top of the sealing strip 17. Then, the sealing cover 14 is closed, and the sealing ring 16 and the high-temperature resistant silicone strip 15 are used to enhance the sealing. The parameters are set through the control panel 18 and the device is started. The motor 8 drives the valve plate 7 to open, and the vacuum pump draws air from the vacuum chamber 2 through the suction pipe 4 and the suction hole 3. During the suction, the filter screen plate 13 and the filter mechanism 21 perform multi-stage filtration, and the vacuum gauge 19 displays the vacuum degree in real time. After the set vacuum degree is reached, the motor 8 drives the valve plate 7 to close, and the sealing strip ensures the seal. At the same time, the sealing strip 17 heats up and cooperates with the high-temperature resistant silicone strip 15 to press the packaging bag tightly and complete the sealing. After sealing, the vacuum chamber 2 returns air to balance the pressure. The sealing cover 14 is opened and the food is taken out. If packaging is required, the operation is repeated. When stopping use, the power is turned off. If necessary, the filter screen cylinder 9 can be removed for cleaning or replacement.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
