[0031] In actual application, the beef automatic packaging machine has a first station a1, a second station a2, a third station a3 and a fourth station a4 in the circumferential direction. The turntable 201 is fixedly mounted on the main shaft 103. By controlling the rotation angle of the main shaft 103 in the xoy plane, the turntable 201 can be driven to rotate in the xoy plane. The plurality of positioning grooves 202 on the turntable 201 are fixedly provided with a shell base 301. The shell base 301 is fixedly mounted on the main shaft 103. The side slide grooves 302 on both sides are equipped with side tooth plates 303 that slide along the first direction x, and the side tooth plates 303 are meshed with the transmission gear 304. When the transmission gear 304 rotates under the drive of an external force, the side tooth plates 303 can be driven to move in the first direction x. Since the support plate 307 is fixedly connected to the side tooth plates 303, the support plate 307 can be synchronously pulled to move in the first direction x. The top of the support plate 307 is rotatably equipped with two sets of flaps 309, and the two sets of flaps 309 are mirror images. A rotating shaft is arranged on the support plate 307 and close to one side of the middle of the support plate 307. Trigger rods 401 are rotatably arranged at both ends of the support plate 307. L-shaped rods 402 at both ends of the trigger rod 401 are fixedly connected by a detection rod 403. A feeding mechanism 6 is arranged on one side of the first station a1. The feeding mechanism 6 is used to push the beef vacuum bag to be packaged to the first station a1. When the vacuum bag to be packaged is pushed to the side of the first station a1, the vacuum bag rotated to the second station a2 enters the vacuum chamber for vacuuming and hot pressing packaging at the same time, and the vacuum bag rotated to the third station a3 enters the high-pressure chamber for pressurization to detect the air tightness of the vacuum bag. At the same time, the vacuum bag that has been packaged and has passed the air tightness test is synchronously unloaded from the fourth station a4, so that the four groups of stations in the packaging machine are operated synchronously. While improving the packaging efficiency, it can also automatically screen and pick according to the sealing state of the vacuum bag, so as to screen out the vacuum bag with insufficient air tightness, and further improve the product yield.

[0032] Furthermore, the spindle 103 is preferably driven by a stepper motor to accurately control the rotation angle of the turntable 201 in the xoy plane, thereby switching to different workstations.

[0033] See also Figure 5 and Figure 7 In a preferred embodiment of the present invention, the carrier assembly 3 also includes a reset plate 305, a guide rod 306, a recovery groove 308, a hot pressing groove 310 and a limit pin 311, the reset plate 305 is fixedly connected between the two sets of side tooth plates 303, the guide rod 306 is fixedly assembled in the shell base 301 and a spring is sleeved thereon, one end of the reset plate 305 is slidably connected to the guide rod 306, and the other end of the reset plate 305 is movably abutted against the spring, the recovery groove 308 is arranged in the middle of the support plate 307, the hot pressing groove 310 is arranged on the surface of the flap 309, and the limit pin 311 is slidably inserted on one side of the flap 309.

[0034] In actual application of this embodiment, the recovery groove 308 is arranged in the middle of the support plate 307 and is arranged between the two groups of flaps 309. One end of the flap 309 is slidably equipped with a limit pin 311, and the limit pin 311 is movably buckled with one end of the support plate 307 to keep the upper surface of the flap 309 horizontal, and the spring between the flap 309 and the support plate 307 is in a compressed state. When the vacuum bag loaded on the flap 309 enters the airtightness detection chamber, if the vacuum bag on any group of flaps 309 is sealed, When there is a problem of insufficient airtightness of the vacuum bag on the group of flaps 309, the limit pin 311 on the side of the group of flaps 309 retracts into the flap 309 under the pushing action, so that the spring at the bottom of the flap 309 pushes the flap 309 to rotate around the fixed axis, and then the flap 309 is switched to a tilted state, so that the vacuum bag loaded on it slides into the recovery groove 308 under the action of gravity. If the vacuum bag on the group of flaps 309 does not have the problem of insufficient airtightness, the group of flaps 309 remains in a horizontal state and the vacuum bag is unloaded after rotating to the fourth station a4.

[0035] Furthermore, the spring installed on the guide rod 306 can push the reset plate 305 to automatically reset, so that when the driving source at one end of the transmission gear 304 disappears, the support plate 307 can automatically reset and shrink.

[0036] Furthermore, a heat pressing sealer is provided in the vacuum box assembly 5, and the welding head position of the heat pressing sealer matches the heat pressing groove 310, so that the vacuum bag to be packaged is sealed by the heat pressing sealer after entering the vacuum chamber and being evacuated.

[0037] See also Figure 3 In a preferred embodiment of the present invention, the detection component 4 also includes a central tooth 404, a first bevel gear 405, a second bevel gear 406, a first trigger tooth group 407 and a second trigger tooth group 408, the central tooth 404, the first bevel gear 405 and the second bevel gear 406 are all fixedly arranged on the trigger rod 401, the first trigger tooth group 407 and the second trigger tooth group 408 are both fixedly assembled on one side of the support plate 307, and the first trigger tooth group 407 and the second trigger tooth group 408 are respectively connected to the first bevel gear 405 and the second bevel gear 406 in transmission.

[0038] In actual application of this embodiment, the trigger rod 401 is fixedly provided with a central tooth 404, a first bevel gear 405 and a second bevel gear 406. When the carrier assembly 3 is located at the first station a1 for loading the vacuum bag, the vacuum bag to be packaged is pushed to the two sets of flaps 309, and the packaging port is located on the hot pressing groove 310. At this time, the trigger rod 401 is driven to rotate counterclockwise along the yoz plane, so that the detection rod 403 assembled at the end of the L-shaped rod 402 abuts against the surface of the vacuum bag. At this time, the turntable 201 is driven to rotate clockwise along the xoy plane, so that the vacuum bag at the first station a1 is rotated to the second station a2 for vacuuming and hot pressing sealing. During the sealing process, since the air in the vacuum bag is continuously extracted, the volume of the vacuum bag is continuously reduced, so that the detection rod 403 abutting against the surface of the vacuum bag drives the trigger rod 401 to move counterclockwise in the yoz plane.

[0039] Furthermore, the trigger rod 401, the L-shaped rod 402 and the detection rod 403 are all lightweight rods, and the effect of their own mass on the pressure of the vacuum bag is negligible.

[0040] Furthermore, the detection component 4 also includes a first ratchet tooth plate 409 and a second ratchet tooth plate 410, the first ratchet tooth plate 409 and the second ratchet tooth plate 410 are both fixedly assembled on one side of the shell base 301, and the first ratchet tooth plate 409 and the second ratchet tooth plate 410 are respectively connected to the first trigger tooth group 407 and the second trigger tooth group 408 for transmission, the first ratchet tooth plate 409 and the second ratchet tooth plate 410 are provided with reverse elastic plates for limiting the rotation direction of the first trigger tooth group 407 and the second trigger tooth group 408 in the first direction x, the first ratchet tooth plate 409 is only transmitted with the first trigger tooth group 407 in the negative direction of the first direction x, and the second ratchet tooth plate 410 is only transmitted with the second trigger tooth group 408 in the positive direction of the first direction x, when the support plate 307 slides in the positive direction of the first direction x, the support plate 307 moves toward the end away from the shell base 301, and when the second When the trigger tooth group 408 contacts the second ratchet tooth plate 410, the second trigger tooth group 408 and the second ratchet tooth plate 410 further drive the second bevel gear 406 to rotate during the transmission process, and drive the trigger rod 401 to rotate clockwise in the yoz plane through the second bevel gear 406, so that the detection rod 403 abutting against the surface of the vacuum bag rotates toward the side away from the vacuum bag, and the detection rod 403 is separated from the surface of the vacuum bag under the action of inertia, and when the support plate 307 slides along the negative direction of the first direction x, the support plate 307 moves toward the end close to the shell base 301, and when the first trigger tooth group 407 contacts the first ratchet tooth plate 409, the first trigger tooth group 407 and the first ratchet tooth plate 409 further drive the first bevel gear 405 to rotate during the transmission process, and drive the trigger rod 401 to rotate counterclockwise in the yoz plane through the first bevel gear 405, so that the detection rod 403 rotates toward the vacuum bag side.

[0041] Furthermore, the sliding abutment between the first ratchet tooth plate 409 and the second ratchet tooth plate 410 and the first trigger tooth group 407 and the second trigger tooth group 408 is regarded as an instantaneous action, so that the detection rod 403 switches from the abutment state to the open state, or from the open state to the abutment state under the action of inertia.

[0042] See also Figure 6 In a preferred embodiment of the present invention, the detection component 4 also includes an unlocking block 411, a single tooth groove 412, a pressure plate 413 and a locking groove 414. The unlocking block 411 is elastically slidably assembled on one side of the support plate 307, and a single tooth groove 412 is provided at one end of the unlocking block 411. The single tooth groove 412 is movably abutted against the middle tooth 404. A pressure plate 413 is also fixedly provided at one end of the unlocking block 411. The locking groove 414 is provided on one side of the support plate 307 and is movably engaged with the limit pin 311.

[0043] When the present embodiment is actually applied, the unlocking block 411 is elastically slidably assembled on the supporting plate 307 along the third direction z. When the trigger rod 401 rotates clockwise in the yoz plane, the middle tooth 404 pushes the single tooth groove 412 to the negative direction of the third direction z. At this time, the pressure plate 413 on one side of the unlocking block 411 does not contact the limit pin 311. When the trigger rod 401 rotates counterclockwise in the yoz plane, the middle tooth 404 pushes the single tooth groove 412 and the unlocking block 411 to move in the positive direction of the third direction z during the rotation process, so that the unlocking block 411 drives the pressure plate 413 to move synchronously in the positive direction of the third direction z. When the pressure plate 413 abuts against one end of the limit pin 311, the limit pin 311 is retracted into the inside of the flap 309, so that the limit pin 311 slides out from one end of the locking groove 414, thereby causing the flap 309 to tilt and rotate after being released from the limit.

[0044] Furthermore, when the vacuum bag is evacuated in the vacuum chamber, if there are obvious air holes at the sealing port of the vacuum bag, the interior of the vacuum bag begins to be filled with air during the process of restoring the vacuum chamber to normal pressure, so that the inner cavity volume of the vacuum bag increases, thereby expanding the vacuum bag body, thereby pushing the detection rod 403 to move in the positive direction of the third direction z. When the vacuum bag after screening enters the pressurized chamber, if there are hidden air holes on the sealing port side of the vacuum bag, the pressurized chamber can break through the hidden air holes during the pressurization process to fill the air back into the vacuum bag, so that the vacuum bag pushes the detection rod 403 to move in the positive direction of the third direction z during the expansion process, and further controls the flap 309 to tilt and rotate, so as to transport the vacuum bag with insufficient sealing to the recovery tank 308.

[0045] See also Figure 4 In a preferred embodiment of the present invention, the vacuum box assembly 5 includes a vacuum chamber 501, a high-pressure chamber 502, a lifter 503, a first conduit 504 and a second conduit 505.

One end of the lifter 503 is fixedly assembled on the top plate 102, and the movable shaft at the other end of the lifter 503 is fixedly connected to the vacuum chamber 501 and the high-pressure chamber 502. The vacuum chamber 501 and the high-pressure chamber 502 are also respectively provided with a first conduit 504 and a second conduit 505.

[0046] In actual application of this embodiment, the vacuum chamber 501 and the high-pressure chamber 502 are both assembled on the top plate 102 for limited sliding along the third direction z. The lifter 503 can drive the vacuum chamber 501 and the high-pressure chamber 502 to reciprocate in the third direction z when driven. The vacuum chamber 501 and the high-pressure chamber 502 are respectively provided with a first duct 504 and a second duct 505. During the vacuuming process, the vacuum chamber 501 can transport the evacuated air to the high-pressure chamber 502 for pressurization, so that the second station a2 and the third station a3 where the vacuum chamber 501 and the high-pressure chamber 502 are located can work synchronously.
