[0002] Aquatic feed is a crucial material basis for aquatic animal farming, and its preservation quality directly impacts farming efficiency. Because aquatic feed is rich in nutrients such as protein and fat, it is highly susceptible to moisture absorption and oxidation during storage, leading to a decline in nutritional value and even the formation of harmful substances. Vacuum packaging technology, by removing air from the packaging bag, effectively inhibits the growth of aerobic microorganisms, prevents feed oxidation and spoilage, and thus significantly extends the shelf life of the feed.

[0017] Furthermore, the internal support assembly 22 includes a motor 221, a lead screw 222, a slider 223, a vertical plate 224, a plug rod 225, a first spring 226, a support plate 227, and an arc-shaped variable track slide 228; Motor 221 is fixed on support frame 4; The lead screw 222 is coaxially and fixedly connected to the output end of the motor 221, and the two ends of the lead screw 222 are respectively provided with forward and reverse threads; Two sliders 223 are threadedly connected to both ends of the lead screw 222. The sliders 223 are slidably inserted into the through slots 41 opened on the top surface of the support frame 4, and the sliders 223 extend to the bottom of the through slots 41. One end of the insertion rod 225 is fixed on the vertical plate 224, and the insertion rod 225 is non-removable but slidably inserted into the slider 223; The first spring 226 is sleeved on the outside of the insert rod 225, and the two ends of the first spring 226 abut against the vertical plate 224 and the slider 223 respectively. The vertical plate 224 is mounted on the slider 223 via the insert rod 225; The support plate 227 is fixed to the bottom of the vertical plate 224. A vertically extending sub-plate 2271 is fixed to the top surface of the end of the support plate 227 away from the middle of the workbench 1.

[0019] In use, place the packaging bag on the workbench 1 with the opening of the bag facing the support plate 227. Activate the electric actuator 211, which moves the mounting plate 212 downwards. The mounting plate 212 then moves the suction cup 214 downwards until the suction cup 214 contacts the upper surface of the packaging bag. Activate the air pump connected to the suction cup 214 to provide negative pressure inside the suction cup 214. The electric actuator 211 shortens, and the suction cup 214 lifts the upper layer of the packaging bag. The lower layer remains on the workbench 1 under the action of gravity and electrostatic force, thus separating the upper and lower layers of the packaging bag and opening the bag opening.

[0020] Subsequently, the motor 221 is started, which drives the lead screw 222 to rotate, further driving the two sliders 223 to move away from each other. The two sliders 223 drive the two vertical plates 224 to move away from each other. Under the push of the arc-shaped variable track slide 228, the vertical plates 224 gradually enter the packaging bag until the auxiliary plate 2271 contacts the edges on both sides of the packaging bag. At this time, the inside of the packaging bag is supported by the auxiliary plate 2271, which facilitates the entry of block aquatic feed into the packaging bag.

[0021] Place the block-shaped aquatic feed on workbench 1, with one side close to push plate 34. Start drive cylinder 31, which moves push plate 32 closer to the packaging bag, further moving push plate 34 and the block-shaped aquatic feed closer to the bag. Continue until push plate 34 contacts limit plate 37, at which point part of the aquatic feed is inside the packaging bag. Drive cylinder 31 extends further, moving push plate 32, and vacuum extraction pipe 36 extends from push plate 34, its end pushing the aquatic feed into the packaging bag. Motor 221 reverses, allowing support plate 227 to move out of the packaging bag, at which point vacuuming can begin.

[0022] It should be noted that this device can be used with commercially available heat sealing knives. The installation position of the heat knife can be adjusted according to the actual situation, which will not be elaborated in this application.
