As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0018] As Figures 1 - 5As shown in the figure, a moving and transporting device for a vacuum packaging machine includes a fixed horizontal translation guide rail 100 at the bottom. A moving and transporting mechanism 200 and a material receiving and conveying mechanism 300 capable of horizontal movement are provided on the translation guide rail. The moving and transporting mechanism 200 is located on the left side, and the material receiving and conveying mechanism 300 is located on the right side. The moving and transporting mechanism 200 includes a transporting frame 210 and a liftable shaping mold 220 with an open top. The material receiving and conveying mechanism 300 includes a material receiving frame 310 and a liftable material receiving conveyor 320. This moving and transporting device is arranged below the material filling mechanism 400 and the vacuum pumping and heat sealing mechanism 500 of the vacuum packaging machine. The material filling mechanism 400 and the vacuum pumping and heat sealing mechanism 500 do not fall within the scope of the present invention, and their structures and principles will not be specifically described here. Existing material filling mechanisms and vacuum pumping and heat sealing mechanisms in the prior art can be adopted. The present invention mechanizes the transportation of the vacuum bag between two workstations on the left and right (i.e., the filling workstation and the heat sealing workstation) and the conveying and discharging of the vacuum bag after heat sealing, which is completed by mechanical control with low manual participation, saving labor costs and improving production efficiency. The entire process flow is smooth and compact, easy to operate, and greatly improves the overall performance of the machine. The vacuum bag filled at the filling workstation falls into the shaping mold, and the vacuum bag is shaped using the inner cavity shape of the shaping mold. Moreover, by the horizontal movement of the shaping mold, the vacuum bag is transported to the heat sealing workstation for vacuum pumping and heat sealing. The vacuum bag after heat sealing is conveyed and discharged by the material receiving and conveying mechanism 300. This moving and transporting device makes the layout of the entire vacuum packaging machine reasonable, occupying a small space and being light in weight.

[0019] In this embodiment, the transporting frame 210 is driven to move horizontally by a translation cylinder 110. A mold lifting frame 240 driven to lift by a mold lifting cylinder 230 is provided on the transporting frame 210. The shaping mold 220 is installed on the mold lifting frame 240. A gate 221 is provided on one side of the shaping mold 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 mold.

[0020] In this embodiment, the shaping mold 220 is cylindrical with a rectangular cross-section, and a vibrator 250 is installed on the outside of the shaping mold 220.

[0021] 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 material filling mechanism 400, so that the vacuum bag drops into the shaping die at a height not too high, avoiding the rupture of the vacuum bag and ensuring that the bag mouth can completely break away from the lower end of the material filling mechanism 400. 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 to perform vacuum pumping and heat sealing on 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 material filling mechanism 400, the material filling mechanism 400 unloads the bag, the vacuum bag drops into the shaping die, and then the shaping die descends. The mobile conveying mechanism 200 is driven by a translation cylinder to move right along the translation guide rail. During the rightward 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 and transports the vacuum bag below 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 stations.

[0022] 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, the receiving and conveying mechanism 300 is driven to move synchronously through the linkage rod 260. The receiving frame 310 is provided with a receiving lifting frame 350 driven by a servo motor 330 through a lead screw 340. A nut seat threadedly engaged 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.

[0023] 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 height setting and the discharging height setting can be carried out according to the different forming heights of different packaging specifications, with strong versatility and good flexibility.

Moreover, the enumerated numerical values should not constitute a limitation on the protection scope of the present invention.

[0025] If the present utility model discloses or involves components or structural members that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), or can also be understood as: a non-detachable fixed connection (for example, riveting, welding).
