Description

Technical Field

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

[0002] Vacuum packaging is a packaging method that removes all or part of the air from the packaging container, creating a near-vacuum state inside.

[0003] In the use of a food vacuum packaging machine, multiple food-filled bags are first placed on the vacuum platform and pressed down with pressure strips. Next, the vacuum pump is started, and the device begins to extract air from the bags, creating a near-vacuum environment that effectively isolates oxygen. Then, the device automatically performs a heat-sealing operation, using high temperature to fuse and seal the bags, ensuring a sustained vacuum. After the seal cools and solidifies, the vacuum packaging machine's door is opened, and the vacuum-packed food is removed, thus completing the vacuum packaging operation for multiple food bags.

[0004] The shortcomings of the existing technical solutions are as follows: In current food vacuum packaging production workshops, workers must manually arrange each packaging bag precisely in its corresponding position on the worktable and then press it with the sealing strip, which is prone to errors. Furthermore, the equipment can only process a small number of packaging bags per batch, making it difficult to meet the needs of large-scale production. After processing a batch, the finished products must be removed one by one. The entire process has low equipment capacity, reducing production efficiency and increasing time costs. Utility Model Content

[0005] This invention provides a food vacuum packaging device that can solve the technical problem of low overall efficiency of existing food vacuum packaging machines.

[0006] A food vacuum packaging device includes a vacuum chamber with a movable cover hinged to its upper end. A negative pressure control component is installed on the vacuum chamber. A conveyor belt platform is fixedly installed inside the vacuum chamber, and a conveyor belt is fitted onto the platform. Side connecting belts are installed on both sides of the conveyor belt. Multiple sets of transversely arranged ceramic pressure plates are equidistantly arranged on the conveyor belt, with each set of ceramic pressure plates fixedly connected to a corresponding side connecting belt at both ends. Multiple sets of heat-sealing plates are equidistantly fixedly arranged on the movable cover, with the gap between adjacent sets of heat-sealing plates being the same as the gap between adjacent sets of ceramic pressure plates.

[0007] As a further embodiment of this utility model: multiple sets of isolation belts are arranged at equal intervals on the conveyor belt, and the extension direction of each set of isolation belts is perpendicular to the extension direction of the ceramic pressure plate. The multiple sets of isolation belts and the multiple sets of ceramic pressure plates form a matrix-distributed space for placing packaging bags.

[0008] As a further embodiment of this utility model: the bottom front side of the vacuum chamber is provided with a receiving cavity that is compatible with the width of the conveyor belt platform.

[0009] As a further embodiment of this utility model: a lower edge plate that cooperates with the lower edge of the movable cover is fixedly provided on the edge of the vacuum box, an upper edge plate is fixedly provided on the front side of the movable cover, and a locking component is provided on the upper edge plate and the lower edge plate.

[0010] As a further embodiment of this utility model: the movable cover is provided with a pad for squeezing the packaging bag, and the heat-sealing plates are all arranged on the pad.

[0011] As a further embodiment of this utility model: the negative pressure control component includes a vacuum pump disposed at the bottom of the vacuum chamber, and the output end of the vacuum pump is connected to the inside of the vacuum chamber.

[0012] As a further embodiment of this invention, the vacuum chamber is also equipped with an electric air valve.

[0013] As a further embodiment of this utility model: the locking component includes a buckle that is movably disposed on the front side of the lower edge plate and cooperates with the upper edge plate.

[0014] As a further embodiment of this utility model, a handle is provided on the front side of the movable cover.

[0015] As a further embodiment of this utility model, the edges of the vacuum chamber are all provided with sealing elements.

[0016] The beneficial effects of this utility model are:

[0017] 1. In use, this utility model utilizes multiple sets of isolation belts on the conveyor belt to form a matrix-style placement space with ceramic pressure plates. Each space corresponds to a placement point, allowing workers to quickly place the bag opening against the ceramic pressure plate. After each row is placed, the conveyor belt platform moves the next set of ceramic pressure plates to the front, achieving continuous and rapid placement. Multiple placement points allow for the placement of a large number of bags in a single batch, effectively increasing production output. During collection, after sealing, the movable cover is opened, and the conveyor belt platform is activated. The bags automatically move to the receiving cavity at the bottom front of the vacuum box. The receiving cavity is adapted to the width of the conveyor belt platform and can hold bags. Workers can directly remove the bags to quickly collect the processed bags, simplifying operation, greatly saving collection time, and improving the overall production efficiency of food vacuum packaging.

[0018] 2. In use, when the movable cover is fastened onto the vacuum chamber, the distance between the pad and the upper surface of the conveyor belt is close. Before heat sealing, the pad will compact the food inside the packaging bag. This results in a flat packaging bag after vacuum packaging, ensuring the consistency of the output products. The flat packaging bags can be stacked more tightly, making full use of storage space and further reducing storage and transportation costs. Attached Figure Description

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0025] like Figures 1 to 3 As shown in the figure, this utility model provides a food vacuum packaging device, including a vacuum box 1, a movable cover 2 hinged to the upper end of the vacuum box 1, and a conveyor belt platform 3 fixedly installed inside the vacuum box 1. Side connecting belts 301 are provided on both sides of the conveyor belt 304 on the conveyor belt platform 3, as shown in the figure. Figure 2 As shown, multiple sets of transversely arranged ceramic pressure plates 303 are equidistantly arranged on the conveyor belt 304, and both ends of each set of ceramic pressure plates 303 are fixedly connected to the corresponding side connecting belts 301. Multiple sets of heat-sealing plates 5 are equidistantly and fixedly arranged on the movable cover 2, and the gap between two adjacent sets of heat-sealing plates 5 is the same as the gap between two adjacent sets of ceramic pressure plates 303. Furthermore, multiple sets of isolation belts 302 are equidistantly arranged on the conveyor belt 304, and the extending direction of each isolation belt 302 is perpendicular to the extending direction of the ceramic pressure plates 303. The multiple sets of isolation belts 302 and the multiple sets of ceramic pressure plates 303 form a matrix-distributed space for placing packaging bags.

[0026] During use, workers simply place the packaging bags sequentially into the corresponding spaces, ensuring the bag opening rests against the corresponding ceramic pressure plate 303. Since each ceramic pressure plate 303 corresponds to a row of packaging bags, and after each row is placed, the conveyor belt platform 3 moves the next set of ceramic pressure plates 303 to the front of the conveyor belt platform 3, a rapid placement effect is achieved. Furthermore, due to the multiple placement points, many packaging bags can be placed in each operation, ensuring production efficiency. After placement, the worker closes the movable cover 2, at which point the bag opening is located between the heat-sealing plate 5 and the ceramic pressure plate 303. Heating by the heat-sealing plate 5 melts and solidifies the bag opening, completing the sealing operation.

[0027] In another specific embodiment, the interior of the movable cover 2 is provided with a pad 203 for compressing the packaging bag, and the heat-sealing plates 5 are all disposed on the pad 203. When the movable cover 2 is fastened onto the vacuum chamber 1, the pad 203 is close to the upper surface of the conveyor belt 304, which facilitates the compaction of the food inside the packaging bag, making the packaging bag as flat as possible after vacuum packaging, thereby ensuring the consistency of the output products, preventing inconsistent shapes, and facilitating storage and transportation.

[0028] The vacuum chamber 1 has a receiving cavity 103 at its front bottom that is adapted to the width of the conveyor platform 3. After sealing, the operator can open the movable cover 2, moving the heat-sealing plate 5 away from the ceramic pressure plate 303, and then start the conveyor platform 3 to move the packaging bags on the conveyor belt 304 into the receiving cavity 103, thus completing the collection operation. Bags can be placed inside the receiving cavity 103 for quickly collecting the processed packaging bags.

[0029] A handle 202 is provided on the front side of the movable cover 2 for easy opening by the operator. A lower edge plate 101, which mates with the lower edge of the movable cover 2, is fixedly provided on the edge of the vacuum chamber 1. An upper edge plate 201 is fixedly provided on the front side of the movable cover 2. Buckles 102 are fitted onto the upper edge plate 201 and the lower edge plate 101. When the movable cover 2 is fastened onto the vacuum chamber 1, the upper edge plate 201 presses against the lower edge plate 101. The operator then engages the buckles 102 to secure the upper edge plate 201 and the lower edge plate 101 together. Sealing elements are provided on the edges of the vacuum chamber 1 to ensure a tight seal inside.

[0030] The vacuum chamber 1 is equipped with a negative pressure control component, which includes a vacuum pump 4 located at the bottom of the vacuum chamber 1, with the output end of the vacuum pump 4 connected to the interior of the vacuum chamber 1. Additionally, the vacuum chamber 1 is equipped with an electric air valve 6 for controlling the air pressure inside the vacuum chamber 1. The vacuum pump 4 creates a negative pressure environment inside the vacuum chamber 1. After a period of time, the bag opening is heat-sealed, and then the electric air valve 6 opens, allowing outside air to enter the vacuum chamber 1, thus eliminating the negative pressure inside the vacuum chamber 1 and facilitating the opening of the movable cover 2 by the operator.

[0031] In the conveyor belt platform 3, multiple sets of support steel are provided in the middle of the conveyor belt 304, and the position of the support steel corresponds to the hot-press sealing plate 5 to ensure the support effect on the conveyor belt and the items on it.

[0032] Working Principle: Before starting work, the movable cover 2 is in the open state, and the conveyor platform 3 is stationary. Workers place the packaging bags sequentially onto the conveyor belt 304. Multiple sets of isolation strips 302 are evenly spaced on the conveyor belt 304, and these isolation strips 302 are perpendicular to the ceramic pressure plates 303, forming a matrix-like placement space. Each space corresponds to one packaging bag placement point. Workers place the opening of the packaging bag against the corresponding ceramic pressure plate 303. After each row of packaging bags is placed, the conveyor platform 3 starts, moving the next set of ceramic pressure plates 303 to the front of the conveyor platform 3 to continue placing new packaging bags. This cycle continues until all placement points are full of packaging bags. Because there are multiple placement points, a large number of packaging bags can be placed simultaneously, effectively improving placement efficiency.

[0033] After the packaging bag is placed, the worker uses handle 202 to fasten the movable cover 2 onto the vacuum chamber 1. At this time, the upper edge plate 201 presses against the lower edge plate 101, and the worker fastens the buckle 102 to fix the upper edge plate 201 and the lower edge plate 101 together, ensuring that the vacuum chamber 1 is sealed. At this time, the opening of the packaging bag is located between the heat-sealing plate 5 and the ceramic pressure plate 303.

[0034] Because the top of the movable cover 2 is equipped with a pad 203, and the pad 203 is close to the upper surface of the conveyor belt 304, the pad 203 will compact the food inside the packaging bag, making the packaging bag flat, ensuring that the output product has a consistent shape, and facilitating storage and transportation.

[0035] Next, vacuum pump 4 is started. Vacuum pump 4 begins to work, extracting the air from vacuum chamber 1 and gradually creating a negative pressure state inside vacuum chamber 1. Under negative pressure, the air inside the packaging bag is extracted, achieving preliminary vacuum packaging.

[0036] After a period of time, when the preset negative pressure value is reached inside the vacuum chamber 1, the heat-sealing plate 5 begins to heat up. The heat from the heat-sealing plate 5 melts and solidifies the opening of the packaging bag, completing the sealing operation. After the sealing operation is completed, the electric air valve 6 opens, and outside air enters the vacuum chamber 1 through the electric air valve 6, causing the negative pressure inside the vacuum chamber 1 to gradually disappear until it returns to normal atmospheric pressure.

[0037] After the negative pressure disappears, the staff releases the buckle 102 and lifts the movable cover 2 using the handle 202, moving the heat-sealing plate 5 away from the ceramic pressure plate 303. The conveyor belt platform 3 is restarted, and the conveyor belt 304 moves the vacuum-packed and sealed bags forward until they enter the receiving cavity 103 at the bottom front of the vacuum chamber 1, which is adapted to the width of the conveyor belt platform 3. Bags can be placed in the receiving cavity 103, allowing staff to easily remove the bags and quickly collect the processed packaging bags, completing the entire food vacuum packaging process.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
