Description

Technical Field

[0001] This utility model relates to the technical field of vacuum packaging machines, specifically a vacuum chamber depth adjustment mechanism for a vacuum packaging machine. Background Technology

[0002] Vacuum packaging involves removing all air from a packaging container and sealing it, maintaining a high-pressure state inside the bag. The scarcity of air creates a low-oxygen environment, depriving microorganisms of the conditions for survival, thus ensuring the freshness of fruits and preventing spoilage. It is currently the most common packaging method for some foods. Traditional vacuum packaging machines have a fixed storage capacity, which is insufficient for larger bags, lacking an adjustable storage space mechanism; furthermore, they lack mechanisms for auxiliary vibration to balance the material during packaging. Therefore, we propose a vacuum chamber depth adjustment mechanism for vacuum packaging machines to address these issues. Utility Model Content

[0003] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes a vacuum chamber depth adjustment mechanism for a vacuum packaging machine, including a machine body, an air pump and an electric heating plate. An organic cover is installed on the top of the vacuum chamber of the machine body, the electric heating plate is installed on one side of the vacuum chamber of the machine body, and the air pump is installed in the inner cavity of the machine body.

[0004] The vacuum chamber of the machine body is equipped with a material plate, and the bottom of the material plate is equipped with a cylinder, which is installed through the top of the inner cavity of the machine body;

[0005] The cylinder has a connecting plate at its movable end, and the connecting plate is connected to the material plate by a spring. A vibration motor is installed at the bottom of the material plate.

[0006] Preferably, the connecting plate has a through groove inside, and the vibration motor is located inside the through groove.

[0007] Preferably, the connecting plate and the cylinder are fixedly connected by a bracket, and four springs are configured and respectively set at the four corners of the material plate.

[0008] Preferably, the air pump is connected to the vacuum chamber of the machine body via a connecting pipe, and a pressure plate is provided above the heating plate. The pressure plate is installed at the bottom of the machine cover via an elastic element.

[0009] Preferably, a plurality of vent pipes are provided through the side wall of the machine body, and a filter screen is provided inside the vent pipe.

[0010] The beneficial technical effects of this utility model are as follows: by setting a material plate in the vacuum chamber of the machine body and driving it with a cylinder, the height of the material plate can be controlled. When the food packaging volume is large, the material plate can be moved down; when the food packaging volume is small, the material plate can be moved up, thereby adjusting the space of the vacuum chamber. At the same time, it is convenient for the electric heating plate to heat-press the food packaging, making the application range of this vacuum packaging machine wider.

[0011] By setting a connecting plate between the material plate and the cylinder, and with the spring setting, the material plate can bounce. When the vibration motor works, it can vibrate the packaged food on the top of the material plate evenly, so as to improve the vacuum effect of the packaging, which has certain practicality.

[0014] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0015] This utility model proposes a vacuum chamber depth adjustment mechanism for a vacuum packaging machine, including a machine body 1, an air pump 2, and an electric heating plate 3. A cover 11 is installed above the vacuum chamber of the machine body 1, and the cover 11 is rotatably connected to the machine body 1, thereby enabling the opening and closing of the vacuum chamber at the top of the machine body 1. The electric heating plate 3 is installed on one side of the vacuum chamber of the machine body 1, and a pressure plate 31 is provided above the electric heating plate 3. The pressure plate 31 is installed at the bottom of the cover 11 via an elastic element, which is a spring, to press the sealing end of the packaging bag, thus ensuring the packaging... The gas inside the bag can be discharged here. Air pump 2 is installed inside the machine body 1. Air pump 2 is connected to the vacuum chamber of machine body 1 via a connecting pipe 21. Air pump 2 can supply air into the vacuum chamber through the connecting pipe 21, compressing the gas inside the packaging bag and discharging it. Several permeable pipes 22 are arranged through the side wall of machine body 1. Filters are installed inside the permeable pipes 2. Under the operation of air pump 2, gas can be absorbed at the permeable pipes 22, and the filter design achieves the purpose of filtering air. A material plate 4 is provided inside the vacuum chamber of machine body 1. A cylinder 5 is located at the bottom of the machine body 1, and is installed through the top of the inner cavity. A material plate 4 is placed in the vacuum chamber of the machine body 1. Driven by the cylinder 5, the height of the material plate 4 is controlled, adjusting the space of the vacuum chamber and facilitating the heat pressing of the heating plate 3 for sealing the food packaging. A connecting plate 6 is provided at the movable end of the cylinder 5. The connecting plate 6 is connected to the material plate 4 by springs 7. Four springs 7 are arranged and placed at the four corners of the material plate 4. A vibration motor is installed at the bottom of the material plate 4. A vibration motor is installed between the material plate 4 and the cylinder 5. The connecting plate 6 is placed, and the spring 7 enables the material plate 4 to bounce. When the vibration motor 8 works, it can vibrate the packaged food on the top of the material plate 4 evenly to improve the vacuum effect of the packaging. The connecting plate 6 has a through groove 61 inside, and the vibration motor is located inside the through groove 61. This design can further hide the vibration motor and ensure sufficient space in the vacuum chamber. The connecting plate 6 and the cylinder 5 are fixedly connected by a bracket 62. Since the cylinder 5 is configured as one, the connecting plate 6 can be aligned and connected by the bracket 62.

[0017] Working principle: When vacuum packaging of food is required, the machine cover 11 can be opened and the height of the material plate 4 can be adjusted according to the size of the food and the packaging bag. At this time, the cylinder 5 can be started. The operation of the cylinder 5 can drive the material plate 4 to adjust its height through the bracket 62 and the connecting plate 6, so that when the packaging bag is placed on top of the material plate 4, the sealed end of the packaging bag corresponds to the electric heating plate 3. Then, the packaging bag containing food is placed on top of the material plate 4, and the sealed end of the packaging bag is placed on top of the electric heating plate 3. At this time, the machine cover 11 is closed and the vibration motor is started. Under the operation of the vibration motor, the food inside the packaging bag can be vibrated evenly. Then, the air pump 2 is started, and the air pump 2 can send air into the vacuum chamber through the connecting pipe 21, compressing the gas inside the packaging bag and expelling it. At this time, under the operation of the electric heating plate 3, the heat pressure of the sealed end of the packaging bag is achieved. Then, the machine cover 11 is opened and the vacuum-packed food can be collected.
