[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] 1. A group of movable placing blocks are provided at the center positions of several edges of the workbench, so that the two placing blocks can be adjusted to clamp the packaging bag placed in the middle firmly, which is conducive to the use of different pre-prepared food packaging bags or packaging boxes. Compared with the existing method of directly clamping the two sides of the packaging bag with two clamping blocks, the placing blocks used here can effectively ensure the stability of clamping, and the clamping area is also increased. It will not fall off in the middle due to the small clamping contact point during the rotation process. The placing blocks can also provide a certain support, and the packaging bag will not be hung on the clamping blocks and shake like in the existing method. At the same time, after the packaging bag is clamped firmly by the placing blocks, it will not shake due to the rotational force during the rotation movement, thereby avoiding the pre-prepared food or juice inside from being thrown out, prompting the packaging bag to remain stationary in the placing blocks, so that it is in a static state when the top opening of the packaging bag is hot-pressed and sealed.

[0018] 2. By providing an intermittent rotating part on the supporting bottom plate, the intermittent rotating part will drive the workbench to realize intermittent rotation after being driven, so as to avoid continuous rotation or excessively fast rotation speed, which will reduce the operation of hot pressing and sealing, and avoid loose sealing. The intermittent rotation generated by the intermittent rotating part provides a certain amount of intermittent rest time for the hot pressing and sealing operation, which is conducive to loading and unloading.

[0019] 3. This device is suitable for the film sealing and packaging of small pre-prepared dishes. Compared with the existing medium and large equipment for packaging, it greatly saves costs and is simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Detailed usage and effects of this embodiment:

[0039] During the film sealing process of pre-prepared dishes, the packaging bag is placed in the placement groove 16, driving the third cylinder 25 and the third gas rod 28 to generate a telescopic movement, the third gas rod 28 drives the support shaft 1 29 to move, and the support shaft 1 29 pulls the T-shaped rotating plate 20 to move through the support shaft 2 31. Since the middle part of the T-shaped rotating plate 20 is movably connected to the bottom of the workbench 13 through the shaft rod 5 21, the T-shaped rotating plate 20 will rotate. After the T-shaped rotating plate 20 rotates, the shaft rod 34 on the other side will move with the side groove 32. The adapter plate 19 is movably connected to the bottom of the workbench 13 through the shaft rod 4 set in the middle. When the adapter plate 19 rotates under the cooperation of the side groove 32 and the limit block 2 33, the adapter plate 19 rotates. The connecting plate 19 and the T-shaped rotating plate 20 will simultaneously pull the upper two side placement blocks 15, so that the track sliders arranged on the inner side of the bottom of the placement blocks 15 will slide on the track plate 14. After the placement blocks 15 on both sides move closer to the middle and collide with each other, the side wall of the placement block 15 on one side will collide with the air inlet nozzle 2 53 on the side wall of the placement block 15 on the other side. After being squeezed, the air inlet nozzle 2 53 extends into the air inlet nozzle 1 52, and the internal piston will telescope and slide in the air inlet nozzle 1 52. The gas generated inside the air inlet nozzle 1 52 enters the connected air bag 51, and the air bag 51 expands and squeezes the packaging bag in the placement groove 16 to clamp the packaging bag firmly. At the same time, after the packaging bag is squeezed by the air bag 51, the gas retained inside is discharged.

[0040] Then the fifth air cylinder 11 and the fifth air rod 10 are driven to generate telescopic movement, and the fifth air rod 10 drives the clamp block 3 9 to move, and the driving arm 8 connected to the side end groove of the clamp block 3 9 will rotate at an angle. When the fifth air rod 10 is extended and retracted into the fifth cylinder 11, the clamp block 3 9 pulls the right end of the driving arm 8 backward, and the angle formed between the driving arm 8 and the clamp block 3 9 becomes larger. The spike 7 connected to the top of the driving arm 8 slides on the side of the ratchet 6 and is embedded in the rear ratchet groove, driving the fifth cylinder 11 and the fifth air rod 10 in the reverse direction, and the spike 7 will push the ratchet 6 rotates, and the rotation cycle just pushes the placement block 15 on the workbench 13 forward one side. Each time it rotates, the placement block 15 will be transported forward one side direction, just pushing the placement block 15 to rotate below the hot pressing head 61. After each push and rotation cycle, the fourth cylinder 47 and the fourth gas rod 48 will be driven at the same time to produce telescopic movement, and the fourth gas rod 48 will drive the clamping block 2 49 to slide, and the clamping block 2 49 will pull the clamping arm 50 to rotate, prompting the clamping arm 50 to be clamped in the corresponding clamping slot 42, thereby achieving a positioning effect.

[0041] Finally, the first cylinder 81 and the first gas rod 80 are driven to produce telescopic motion. The first gas rod 80 drives the side plate 54 to produce lifting motion on the side of the fixed plate 83. The side plate 54 slides downward until the hot pressing head 61 is located at the upper periphery of the packaging bag. Then, the second cylinder 78 and the second gas rod 79 are driven to produce telescopic motion. The second gas rod 79 pushes the lifting plate 64 up and down. When the lifting plate 64 moves upward, it will pull the inner side of the movable block 71 upward. The lower part of the movable block 71 will rotate toward the middle. The lower part of the movable block 71 will pull the fixed block 2 59 to slide toward the middle on the second track 57 at the same time. After the hot pressing heads 61 on both sides move closer to the middle, they will press the upper opening of the packaging bag in the middle and perform hot pressing on the upper opening of the packaging bag. After the sealing and packaging is completed, as the intermittent rotating part 3 below rotates to one side, the corresponding third cylinder 25 and the third gas rod 28 are driven to produce telescopic motion, driving the placement blocks 15 on both sides to separate, so that it will be convenient for the operator to unload the material. The telescopic movement of each third air cylinder 25 and the third air rod 28 is connected and controlled individually.

[0042] The above specific embodiments will allow those skilled in the art to easily implement the present invention.
