Description

Technical Field

[0001] This utility model relates to the technical field of seafood processing, and in particular to a vacuum packaging device for seafood. Background Technology

[0002] Vacuum packaging, also known as depressurized packaging, involves removing all the air from the packaging container and sealing it to maintain a high depressurization state inside the bag. The scarcity of air is equivalent to a low-oxygen effect, which eliminates the conditions for microorganisms to survive, thereby ensuring the freshness of the fruit and preventing disease and rot.

[0003] Existing vacuum packaging equipment for seafood, such as the one disclosed in utility model patent application number 201721557552.8, mainly includes a movable support, a main body, and a vacuum cover. The movable support is located on top of the main body and is movably connected to the main body. The vacuum cover is located on top of the main body and is movably connected to the main body via the movable support. The vacuum pump has an internal waterproof layer. In use, the vacuum packaging equipment is moved to the desired position, then the power supply is turned on. The vacuum cover is then placed on the right working platform, and the packaging bag containing the seafood is placed on the left working platform. The opening of the seafood packaging bag is placed on the heating strip. The vacuum cover is then moved to the left working platform via the movable support, so that the vacuum cover is tightly connected to the left working platform. Finally, the switch is pressed.

[0004] However, seafood usually contains a lot of water, blood, or mucus. Existing vacuum equipment can easily extract these liquids along with the seafood, causing equipment failure. Moreover, after packaging, manual depressurization and removal of the packaging are required, which is very troublesome and inefficient. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a vacuum packaging device for seafood that not only prevents liquid leakage from the seafood packaging and ensures stable operation of the device, but also facilitates the discharge of materials after packaging, thereby improving work efficiency.

The sealing mechanism is installed on the working box to enhance the sealing effect of the device. Both sets of discharge mechanisms are installed on the working box to facilitate the discharge of seafood packaging. The sealing mechanism is installed on the working box to seal the seafood packaging. The vacuuming mechanism is installed on the working box to extract air from the device. The operator places the seafood packaging vertically in the working box, then closes the sealing mechanism to ensure the airtightness of the device, activates the vacuuming mechanism to create a vacuum inside the packaging bag, the sealing mechanism seals the seafood packaging, and the two sets of discharge mechanisms open to allow the seafood packaging to fall out.

[0007] Preferably, the working box includes a box body, a controller, and a conveyor belt. The bottom of the box body is connected to the ground, and the inside of the box body is provided with a cavity. The controller is installed on the box body, and the conveyor belt is installed on the box body. The worker places the seafood packaging in the cavity of the box body, and controls the vacuuming and discharging process through the controller. After vacuuming, the seafood packaging falls onto the conveyor belt, and the conveyor belt drives the seafood packaging out.

[0008] Preferably, the sealing mechanism includes a first hinge, a sealing cover, a sealing gasket, a handle, and a pressure gauge. The first hinge is mounted on the box body, the sealing cover is mounted on the first hinge, the sealing gasket is mounted on the sealing cover, the handle is mounted on the sealing cover, and the pressure gauge is mounted on the sealing cover.

Then, the sealing cover is closed, and the sealing gasket is used to seal the top of the cavity of the box body to prevent gas flow. The pressure gauge is used to detect the air pressure inside the cavity of the box body to check the vacuuming effect.

[0009] Preferably, the discharge mechanism includes a second hinge, a support plate, a cylinder, two sets of electric cylinders, and a clamping plate. The second hinge is installed inside the cavity of the box, and the support plate is installed on the second hinge. The two ends of the cylinder are respectively rotatably installed on the inner wall of the box and the bottom end of the support plate. Both sets of electric cylinders are installed inside the cavity of the box, and the clamping plate is installed on the two sets of electric cylinders. The two discharge mechanisms are installed opposite each other inside the cavity of the box. The two sets of support plates support the seafood packaging, and the two sets of electric cylinders push the clamping plate to squeeze the seafood packaging, so that the air inside the seafood packaging is initially discharged and the bottom end of the seafood packaging is fixed to ensure the vertical state of the seafood packaging. After the vacuum is completed, the cylinder pulls the support plate to flip downward, and the two sets of electric cylinders drive the clamping plate to retract, so that the seafood packaging falls naturally under the action of gravity.

[0010] Preferably, the edges of both sets of support plates are covered with sealing strips; by applying sealing strips, the sealing effect of the two sets of support plates when they are closed is enhanced, and air leakage is prevented from affecting the vacuuming effect.

The servo motor drives the lead screw to rotate via the reducer, and the lead screw drives the slider to rise and fall, adjusting the height of the heat sealer to ensure it is positioned at the appropriate packaging height for the seafood packaging. After vacuuming, the heat sealer heat seals the seafood packaging.

[0012] Preferably, the air extraction mechanism includes two sets of air extraction filters, an air extraction pipe, two sets of check valves, and a vacuum pump.
