Description

Technical Field

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

[0002] Vacuum packaging equipment is a specialized machine that removes air from a packaging container and seals it. It uses core components such as vacuum pumps to evacuate the air inside the packaging to a predetermined vacuum level, and then seals the packaging opening through methods such as heat sealing, achieving the effects of isolating air, preventing moisture, and preventing oxidation. It is widely used in the food, pharmaceutical, and electronics industries, extending product shelf life and preventing mold and spoilage. Based on structure, it is divided into tabletop, vertical, and rolling types, and improves packaging efficiency and sealing through automated or semi-automatic operation.

[0003] In related technologies, existing vacuum packaging equipment often experiences displacement of the vacuum bag during vacuum extraction when vacuum sealing marinated fish, which leads to heat seal misalignment and affects the sealing process. Furthermore, existing heat sealing structures are mostly top-down heat sealing, and the pressure decreases with the thickness of the packaging bag. Thin areas may be punctured due to excessive pressure, while thick areas may not be sealed properly due to insufficient pressure.

[0004] Therefore, we propose a vacuum packaging device for marinated fish to solve the above problems. Utility Model Content

A limiting groove is opened on the bottom inner wall of the working chamber, and two threaded sliders 8 are slidably installed on the bottom inner wall of the limiting groove. A positioning metal strip 6 is fixedly installed on the top of each of the two threaded sliders 8.

[0034] In this embodiment, a sealing cover 2 is rotatably installed on one side of the vacuum packaging machine 1. After closing, the working chamber becomes a sealed space, which facilitates vacuum extraction.

[0035] In this embodiment, the vacuum packaging machine 1 has a vacuum chamber inside. A vacuum pump 4 is fixedly installed on the bottom inner wall of the vacuum chamber. An air intake is opened at the top of the vacuum chamber and is connected to the working chamber. An air extraction head 3 is fixedly installed inside the air intake. An air pipe 5 is fixedly installed on the output end of the vacuum pump 4. The other end of the air pipe 5 is fixedly connected to the air extraction head 3, so that the air in the working chamber can be extracted through the air extraction head 3.

[0036] In this embodiment, a forward and reverse toothed ball screw 9 is rotatably installed on one inner wall of the limiting groove. A telescopic dust cover 10 is sleeved on the outer side of the forward and reverse toothed ball screw 9. Two threaded sliders 8 are threadedly sleeved on the same forward and reverse toothed ball screw 9, which facilitates the movement of the two threaded sliders 8 by the forward and reverse toothed ball screw 9.

[0037] In this embodiment, silicone strips 7 are fixedly installed on the side of the two positioning metal strips 6 that are close to each other, which can prevent the positioning metal strips 6 from damaging the vacuum bag.

[0038] In this embodiment, a motor slot is provided inside the vacuum packaging machine 1. A servo motor 11 is fixedly installed on the inner wall of one side of the motor slot. The output shaft of the servo motor 11 is fixedly connected to the forward and reverse toothed ball screw 9. The servo motor 11 can drive the forward and reverse toothed ball screw 9 to rotate.

[0039] In this embodiment, four rising positioning blocks 15 and four falling positioning blocks 19 are fixedly installed on one inner wall of the hot pressing tank. Two rising rods 14 are fixedly installed at the bottom of the rising base 13. The two rising rods 14 slide through the corresponding two rising positioning blocks 15, so as to drive the same rising base 13 to move through the two rising rods 14.

[0040] In this embodiment, the tops of two of the four descending positioning blocks 19 located on the same side are slidably connected to the same descending rod 18. The tops of the two descending rods 18 are fixedly installed with the same descending base 21. The two descending rods 18 slidably connect to the same ascending base 13. The two descending rods 18 can drive the same descending base 21 to move.

[0041] In this embodiment, two gears 17 are rotatably mounted on one inner wall of the hot press groove. An upward rack 16 is fixedly sleeved on the outer side of each of the two rising rods 14, and a downward rack 20 is fixedly sleeved on the outer side of each of the two descending rods 18. The two rising racks 16 and the two descending racks 20 respectively mesh with the corresponding gears 17, so that the corresponding descending racks 20 can be moved by the gears 17 in conjunction with the gears 17.

[0042] In this embodiment, hot pressing strips 22 are fixedly installed on the sides of the rising base 13 and the descending base 21 that are close to each other. Heating wires 23 are fixedly installed inside the two hot pressing strips 22. When the two hot pressing strips 22 move towards the middle at the same time, pressure is applied synchronously from both sides. The influence of local thickness difference can be effectively offset by symmetrical force.

[0043] Working principle: During the vacuum packaging of marinated fish, the operator places the vacuum bag containing the marinated fish into the working chamber of the vacuum packaging machine 1, passes the sealed end of the vacuum bag through two heat-pressing strips 22, and then starts the servo motor 11. The servo motor 11 drives the positive and negative threaded ball screw 9 to rotate, which in turn drives the two threaded sliders 8 to move closer together. The two threaded sliders 8 moving closer together drive the corresponding positioning metal strips 6 to move closer together. The silicone strip 7 on one side of the two positioning metal strips 6 comes into contact with the vacuum bag, limiting its position and reducing the area of ​​the working chamber, thus accelerating the vacuum extraction speed. After the vacuum bag is positioned, the operator closes the sealing cover 2 and starts the vacuum pump 4. The vacuum pump 4 extracts air from the working chamber through the air pipe 5 and the suction head 3. The air in the chamber is removed, and the air between the vacuum bag and the marinated fish is removed. After the air is removed, the electric push rod 12 is activated. The electric push rod 12 drives the rising base 13 to move upward. The rising base 13 drives the two rising rods 14 to move upward. The rising rods 14 drive the corresponding rising racks 16 to move upward. The rising racks 16 drive the corresponding gears 17 to rotate. The rotating gears 17 drive the corresponding descending racks 20 to move downward. The moving descending racks 20 drive the corresponding descending rods 18 to move. The moving descending rods 18 drive the same descending base 21 to move downward. At this time, the two heat-pressing strips 22 squeeze the vacuum bag, and the two heating wires 23 generate heat to heat-seal the vacuum bag, completing the packaging.

[0044] The technological advancements of this invention compared to existing technologies are as follows: during vacuum extraction, the vacuum bag and marinated fish can be positioned to prevent displacement while reducing the effective vacuum extraction volume, thereby accelerating the vacuuming process and improving work efficiency. Furthermore, when the two heat-pressing strips 22 move towards the center simultaneously, pressure is applied synchronously from both sides. The symmetrical force offsets the effects of local thickness differences, ensuring consistent pressure across the sealing edge and preventing damage to thin areas or leakage in thick areas, thus increasing the stability of the sealing process.
