[0046] As a preferred embodiment of the present invention, the packaging method of the vacuum packaging machine includes the following steps:

[0047] S1: Place the braised duck product to be sealed onto the carrier of the circular turntable;

[0048] S2: Based on the operation of the feeding drive unit, it drives the circular turntable to rotate and transport the carrier to the loading and unloading station;

[0049] S3: The translation drive unit drives the translation seat to move to the loading / unloading station;

[0055] S9: The heat sealing component is working to thoroughly heat seal the packaging bag;

[0056] S10: The negative pressure component and heat sealing component are reset, and the transmission component removes the carrier from the packaging station and moves it to the loading and unloading station for exchange.

[0057] S11: Repeat the above cycle until the packaging of each product is completed.

[0058] The beneficial effects of this invention are as follows:

[0059] This invention, by setting up a packaging mechanism and a feeding mechanism, enables the braised duck product to be sealed to be placed in a carrier during packaging. The rotating ring turntable moves the carrier to the loading and unloading chamber. Based on the operation of the transmission component, the carrier is transported to the packaging station for packaging. During the process, the ring turntable can transport the next carrier, which greatly saves time and improves work efficiency.

[0060] This invention, by setting up a turntable, a central deflector, and a carrier adapted to the shape of the central deflector, can switch the positions of the two carriers on the turntable during the loading and unloading process based on the operation of the rotation control motor. This allows packaged products to be sent to the circular turntable, while unpackaged products are sent to the other side of the turntable for easy transport to the packaging station for packaging.

[0061] This invention, by setting a first arc groove, a second arc groove, and an arc-shaped protrusion, can limit the carrier to a certain extent during the conveying or packaging process, preventing structural swaying. When the carrier is removed from the annular turntable, the turntable extends into the groove. At this time, the carrier, based on the cooperation of the arc-shaped protrusion and the first arc groove, fails to fall onto the turntable, ensuring that the turntable is smoothly inserted into the groove. When the turntable rotates, the central lever is used to push the carrier off the annular turntable, and the turntable provides support for the carrier. Finally, under the movement of the structure, the arc-shaped protrusion of the carrier is pushed into the second arc groove.

[0062] This invention, by setting up a metal proximity sensor and a positioning metal piece, enables the metal proximity sensor to detect the positioning metal piece when the carrier is accurately delivered into the packaging station. Based on the signal transmitted by the metal proximity sensor, the control module controls the operation of the negative pressure component and the heat sealing component.

[0063] By incorporating structures such as ball joints and inclined plates, this invention enables the limiting frame to restrict the carrier during transport on a circular turntable. When the transport assembly is transferring the carrier, the ball joints and inclined plates work together to lift the limiting frame upwards, thereby releasing the structural restriction and facilitating the loading and unloading of the carrier, thus improving reliability.

[0072] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0073] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0074] This invention provides a double-chamber automatic vacuum packaging machine for braised duck, such as... Figure 1-7 As shown, it includes a packaging mechanism and a feeding mechanism. The packaging mechanism includes a packaging mechanism body 1, which is provided with a loading / unloading chamber and a packaging chamber. The position of the feeding mechanism is adapted to the position of the loading / unloading chamber.

[0075] The packaging mechanism also includes:

[0076] Negative pressure components are used for vacuuming.

[0077] Heat sealing components are used for sealing packaging.

[0078] The transfer assembly is used for loading and unloading materials between the feeding mechanism and the packaging chamber;

[0079] The feeding mechanism includes:

[0080] Annular seat 2, on which an annular turntable 4 is rotatably mounted;

[0081] The carrier 5 is detachably mounted on the annular turntable 4 in a circumferential arrangement. The carrier 5 is used to carry the braised duck product to be sealed. Linearly paired spring rods 40 are fixed inside the carrier 5, and a clamping plate 17 is fixed to one end of each spring rod 40.

[0082] The feeding drive unit is used to drive the annular turntable 4 to rotate on the annular seat 2.

[0083] By setting up packaging and feeding mechanisms, the braised duck product to be sealed can be placed in carrier 5 during packaging. The rotating ring turntable 4 drives carrier 5 to the loading and unloading chamber. Based on the operation of the transmission component, carrier 5 is transported to the packaging station for packaging. During the process, the ring turntable 4 can transport the next carrier 5, which greatly saves time and improves work efficiency.

[0084] To facilitate the orderly transport of vehicle 5; such as Figure 2-7 As shown, the transmission component includes:

[0085] Translation seat 9, on which a rotation control motor 16 is installed;

[0086] Turntable 42 is rotatably mounted on translation seat 9 via a shaft. The shaft of turntable 42 is connected to the output end of rotation control motor 16. The annular turntable 4 has a groove 34 for turntable 42 to pass through.

[0087] Translation drive unit, which is used to drive translation seat 9 to move between the packaging station in the packaging chamber and the loading / unloading station in the loading / unloading chamber;

[0088] The center lever 15 is fixed to the top of the turntable 42 and has a symmetrical structure. One side of the outer wall of the carrier 5 has a first arc surface structure that matches the annular turntable 4, and the two symmetrical surfaces of the center lever 15 have an arc-shaped structure that matches the first arc surface structure of the carrier 5. The other side of the outer wall of the center lever 15 has a second arc surface structure, and the center of the arc of the second arc surface structure coincides with the rotation center of the turntable 42 at the loading and unloading station. The two carriers 5 can cooperate with the center lever 15 to form a circular structure.

[0089] By setting up a turntable 42, a center lever 15, and a carrier 5 that is adapted to the shape of the center lever 15, the positions of the two carriers 5 on the turntable 42 can be switched based on the operation of the rotation control motor 16 during the loading and unloading process. This allows the packaged products to be sent to the circular turntable 4, while the unpackaged products are sent to the other side of the turntable 42 for easy transport to the packaging station for packaging.

[0090] To improve reliability; such as Figure 6 As shown, the annular turntable 4 is provided with a first arc groove, and the outer wall of the second arc surface structure of the carrier 5 is provided with an arc-shaped protrusion 39, which is adapted to the first arc groove.

[0091] A positioning seat 14 is fixed to one side of the inner wall of the packaging chamber, and a second arc groove 30 adapted to the arc-shaped protrusion 39 is opened on one side of the positioning seat 14.

[0092] By setting the first arc groove, the second arc groove 30, and the arc-shaped protrusion 39, the carrier 5 can be limited to a certain extent during the conveying or packaging process to avoid structural shaking. When the carrier 5 is taken off from the annular turntable 4, the turntable 42 extends into the groove 34. At this time, the carrier 5 fails to fall onto the turntable 42 due to the cooperation of the arc-shaped protrusion 39 and the first arc groove, ensuring that the turntable 42 is smoothly inserted into the groove 34. At this time, the distance between the top surface of the turntable 42 and the bottom surface of the carrier 5 should be designed to be as small as possible. When the turntable 42 rotates, the center lever 15 is used to push the carrier 5 off the annular turntable 4. The turntable 42 provides support for the carrier 5. Finally, under the movement of the structure, the arc-shaped protrusion 39 of the carrier 5 is pushed into the second arc groove 30.

[0093] For ease of automatic control; such as Figure 4 , Figure 6 As shown, the main body 1 of the packaging mechanism is also equipped with a control module. A positioning metal piece 33 is embedded in one side of the arc-shaped protrusion 39, and a metal proximity sensor 29 adapted to the positioning metal piece 33 is embedded in the inner side of the second arc groove 30. The metal proximity sensor 29, the negative pressure component, and the heat sealing component are all connected to the control module.

[0094] By setting up a metal proximity sensor 29 and a positioning metal piece 33, when the carrier 5 is accurately delivered into the packaging station, the metal proximity sensor 29 senses the positioning metal piece 33, and the control module controls the negative pressure component and the heat sealing component to work based on the signal transmitted by the metal proximity sensor 29.

[0095] To improve structural stability; such as Figure 5 , Figure 6 As shown, a pair of limiting components are fixed on the annular turntable 4. The limiting components are used to prevent the carrier 5 from detaching from the annular turntable 4. The limiting components include:

[0096] Guide rod 36, guide rod 36 is fixed to the top outer wall of the annular turntable 4;

[0097] The limiting frame 37 is slidably connected to the outer wall of the guide rod 36. The limiting frame 37 and the annular turntable 4 are connected by a spring 35. The bottom end of the limiting frame 37 has an arc surface structure, and the position of the bottom end of the limiting frame 37 is adapted to the arc-shaped protrusion 39.

[0098] Inclined plate 38, the inclined plate 38 is fixed on the limiting frame 37;

[0099] Based on the force of the spring 35, the bottom of the limiting frame 37 of the two limiting components blocks and limits the two ends of the arc-shaped protrusion 39.

[0100] Ball-head rods 10 are mounted on both sides of the translation seat 9 via side brackets. The top of the ball-head rods 10 has a spherical structure, and the inclined plate 38 is located on the moving path of the top of the ball-head rods 10.

[0101] By setting up structures such as ball head rod 10 and inclined plate 38, the carrier 5 can be limited by the limiting frame 37 when the annular turntable 4 is conveying. When the transmission component is transmitting the carrier 5, the limiting frame 37 can be lifted upward by the cooperation of ball head rod 10 and inclined plate 38, thereby releasing the limitation of the structure, so as to facilitate the loading and unloading of the carrier 5 and improve reliability.

[0102] To facilitate vacuum packaging; such as Figure 2 , Figure 4 As shown, the negative pressure component includes:

[0103] Negative pressure generating device 12 is installed inside the main body 1 of the packaging mechanism;

[0104] Mounting frame 23 is installed on the top inner wall of the main body 1 of the packaging mechanism;
