[0029] As Figures 1 to 10 shown, a vacuum packaging machine includes a material filling mechanism 400 and a vacuum pumping and heat sealing mechanism 500 located beside the material filling mechanism. The material filling mechanism 400 is located on the left side, and the vacuum pumping and heat sealing mechanism 500 is located on the right side. A translation guide rail 100 is provided below the material filling mechanism and the vacuum pumping and heat sealing mechanism. A movable transport mechanism 200 and a material receiving and conveying mechanism 300 capable of horizontal movement are provided on the translation guide rail. The movable transport mechanism 200 is located on the left side, and the material receiving and conveying mechanism 300 is located on the right side; the movable transport mechanism 200 includes a transport frame 210 and a liftable shaping die 220 with an open top, and the material receiving and conveying mechanism 300 includes a material receiving frame 310 and a liftable material receiving conveyor 320. This vacuum packaging machine only requires manual bag loading. After that, metering, filling, vacuum pumping, heat sealing, bag unloading, and conveying are all mechanized and completed by mechanical control, with low manual participation. The entire process flow is smooth and compact, easy to operate, greatly improving the overall performance of the machine, achieving efficient and accurate automatic quantitative packaging, saving labor costs, and improving production efficiency. The vacuum bag after filling falls into the shaping die, and the vacuum bag is shaped using the inner cavity shape of the shaping die. And by using the horizontal movement of the shaping die, the vacuum bag is transported to the vacuum pumping and heat sealing mechanism 500 for vacuum pumping and heat sealing. The vacuum bag after heat sealing is conveyed out by the material receiving and conveying mechanism 300; this vacuum packaging machine has a reasonable layout, occupies a small space, and is light in weight.

[0030] In this embodiment, the transport frame 210 is driven to move horizontally by a translation cylinder 110. A die lifting frame 240 driven to lift by a die lifting cylinder 230 is provided on the transport frame 210. The shaping die 220 is installed on the die lifting frame 240. A gate 221 is provided on the side of the shaping die facing the material receiving and conveying mechanism, and a gate cylinder 222 for controlling the opening and closing of the gate is provided on the side of the shaping die.

[0031] In this embodiment, the shaping die 220 is cylindrical and has a rectangular cross-section. A vibrator 250 is installed outside the shaping die 220.

[0032] The mobile conveying mechanism 200 consists of a horizontal left - right movement and a lifting movement of the shaping die. The lifting movement of the shaping die is driven by a lifting cylinder 230. When the shaping die moves to the left station and rises, it docks with the bag - sleeving cylinder, so that when the vacuum bag falls into the shaping die, its height is not too high, avoiding the rupture of the vacuum bag and ensuring that the bag mouth can completely break away from the bag - sleeving cylinder. When the shaping die moves to the right station and rises, it transports the vacuum bag to the vacuum - pumping and heat - sealing mechanism 500 for vacuum - pumping and heat - sealing of the vacuum bag. The specific movement process of the mobile conveying mechanism 200: The mobile conveying mechanism 200 reaches the left station, the shaping die rises and docks with the bag - sleeving cylinder. After reaching the position, the bag clamp automatically opens to unload the bag, and the vacuum bag falls into the shaping die. Then the shaping die descends, and the mobile conveying mechanism 200 is driven by a translation cylinder to move right along the translation guide rail. During the right - hand movement, the vibrator 250 vibrates the bag of materials to compact them. After the mobile conveying mechanism 200 reaches the right station, the shaping die rises again, transporting the vacuum bag to the lower part of the vacuum - pumping and heat - sealing mechanism. The entire conveying process is smoothly connected, effectively shortening the waiting time between each working step, improving the vacuum - packaging speed of the overall vacuum packaging machine, and enabling efficient and coordinated operation of multiple workstations.

[0033] In this embodiment, the receiving frame 310 and the bottom of the conveying frame 210 are connected by a linkage rod 260. The two ends of the linkage rod 260 are respectively hinged to the bottom of the receiving frame 310 and the conveying frame 210. When the translation cylinder 110 drives the mobile conveying mechanism 200 to move horizontally, it drives the receiving and conveying mechanism 300 to move synchronously through the linkage rod 260. On the receiving frame 310, there is a receiving lifting frame 350 driven by a servo motor 330 through a lead screw 340. A nut seat that is thread - fitted with the lead screw 340 is connected to the receiving lifting frame 350. The receiving conveyor 320 is installed on the receiving lifting frame 350, and guard plates are provided on both sides of the receiving conveyor 320.

[0034] The receiving and conveying mechanism 300 moves horizontally synchronously with the mobile conveying mechanism 200. When the mobile conveying mechanism 200 is located below the material filling mechanism, the receiving and conveying mechanism 300 is located below the vacuum - pumping and heat - sealing mechanism. When the mobile conveying mechanism 200 is located below the vacuum - pumping and heat - sealing mechanism, the receiving and conveying mechanism 300 moves right and exits from below the vacuum - pumping and heat - sealing mechanism. The receiving and conveying mechanism 300 consists of a horizontal movement and a lifting movement of the receiving conveyor. When the receiving and conveying mechanism 300 rises, it receives the vacuum bag that has completed vacuum - pumping and heat - sealing and transports it out. The lifting movement of the receiving conveyor is driven by a servo motor, and the receiving - bag height setting and discharging - height setting can be carried out according to the different forming heights of different packaging specifications, with strong versatility and good flexibility.

[0035] In this embodiment, the material filling mechanism 400 includes a feeding cylinder 410, a metering cylinder 420, a transition hopper 430, and a bagging cylinder 440, which are arranged in sequence from top to bottom. The lower opening of the metering cylinder is provided with a metering gate 460 driven by a metering gate cylinder 450. The metering gate 460 adopts a split design and is composed of left and right parts. Two metering gate cylinders 450 are provided on the left and right. One end of the metering gate cylinder 450 is hinged to the outer side wall of the metering cylinder, and the other end is hinged to the metering gate 460. Bag clamps driven by a bag clamping cylinder 470 are provided on both sides of the bagging cylinder. A blanking gate is provided at the bottom feeding port of the feeding cylinder 410, and the blanking gate is driven by a blanking gate cylinder to open and close. When the system is started, the blanking gate of the feeding cylinder opens to automatically feed the metering cylinder, and the feeding stops after reaching the target value. After manually putting the vacuum bag on the bagging cylinder, the bag clamping cylinder 470 drives the bag clamps to clamp and fix the vacuum bag on the bagging cylinder. The metering gate cylinder drives the metering gate to open and discharge the material, and the material is filled into the vacuum bag through the transition hopper and the bagging cylinder.

[0036] In this embodiment, the vacuum pumping and heat sealing mechanism 500 includes a heat sealing frame 510. Two sealing clamping plates 520 for clamping the bag mouth of the vacuum bag are provided on the lower side of the heat sealing frame 510, one in front and the other behind. A heat sealing plate 522 driven by a heat sealing cylinder 521 to expand and contract is provided on the sealing clamping plate. A pair of liftable bag arranging forks 530 that can move synchronously towards or away from each other are provided in the middle of the lower side of the heat sealing frame 510. A liftable vacuum pumping tube 582 is provided between the two bag arranging forks, and the lower part of the vacuum pumping tube is flat. When the shaping die rises at the right working station, the bag mouth of the vacuum bag is sent between the front and rear sealing clamping plates. Then, the vacuum pumping tube and the bag arranging forks descend, and the two bag arranging forks move away from each other synchronously to arrange the bag. The two sealing clamping plates clamp and seal the bag mouth. Then, the vacuum pumping tube starts to pump vacuum. After the vacuum degree reaches the preset value, the heat sealing plates on the two sealing clamping plates extend to perform heat sealing treatment on the bag mouth. After the sealing clamping plates clamp the bag mouth of the vacuum bag, the shaping die can descend and move to the left working station to transport the next vacuum bag, while the receiving conveyor moves to the lower part of the vacuum pumping and heat sealing mechanism 500 and rises to support the vacuum bag. During this process, the vacuum bag is suspended by the clamping of the sealing clamping plates.

[0037] In this embodiment, a pair of fork mounting seats 560 driven by a synchronous belt 550 to move synchronously towards or away from each other are provided above the heat sealing frame 510. Fork lifting cylinders 561 for driving the bag arranging forks to lift are respectively installed on the two fork mounting seats. The bag arranging forks are connected to the driving ends of the fork lifting cylinders. The synchronous belt is driven by a bag arranging cylinder 570. The two fork mounting seats are respectively connected to one end of the upper side belt and the other end of the lower side belt of the synchronous belt. The bag arranging cylinder drives the bag arranging forks to arrange the bag through the synchronous belt, and the lifting cylinder 561 drives the bag arranging forks to descend and rise to realize the actions of inserting into the bag mouth and withdrawing from the bag mouth.

[0038] In this embodiment, a vacuum tube lifting cylinder 580 for driving the lifting of the vacuum extraction tube is installed in the middle of the heat-sealing machine frame. The driving end of the vacuum tube lifting cylinder faces upward and is connected with a connecting bracket 581, and the upper end of the vacuum extraction tube 582 is connected to the connecting bracket. The vacuum tube lifting cylinder 580 drives the vacuum extraction tube to descend and ascend, realizing the actions of inserting into and withdrawing from the bag mouth.

[0039] In this embodiment, a rotating shaft 540 is rotatably connected to the rear part of the heat-sealing machine frame. A sealing cylinder 590 for driving the rotation of the rotating shaft is arranged below the rear side of the heat-sealing machine frame. A swing arm 541 hinged to the upper end of the sealing cylinder is fixedly connected to the middle of the rotating shaft 540. Rotating plates 542 are respectively and fixedly connected to both ends of the rotating shaft. One end of each rotating plate is connected to the corresponding end of the rear sealing clamp plate through a first connecting rod 543, and the other end is connected to the corresponding end of the front sealing clamp plate through a second connecting rod 544, so that when the sealing cylinder drives the rotating shaft to rotate, it drives the front and rear sealing clamp plates to move synchronously towards or away from each other to realize clamping or loosening. The heat-sealing plates 522 can be slidably installed on the upper sides of the corresponding sealing clamp plates. When the two sealing clamp plates clamp the bag mouth, after the vacuum extraction tube completes vacuum extraction and withdraws, the front and rear heat-sealing plates are driven by their respective heat-sealing cylinders to move towards each other in the middle and extend to heat-seal the bag mouth. After the heat-sealing is completed, the two heat-sealing plates move away from each other synchronously and separate from the bag mouth.
