When the workstation switching disk 103 drives the packaging lower shell 104 to move above the blanking hole 111, the flipping mechanism 3 drives the transfer push plate 108 to rotate downward and open the blanking slot 107. A support frame 105 is fixed to the upper end of the workbench 101, and the packaging upper shell 106 is connected to the lower part of the support frame 105 through a lifting mechanism 6. The blanking hole 111 is not located below the packaging upper shell 106. The lifting mechanism 6 is used to drive the packaging upper shell 106 to move up and down; when the packaging upper shell 106 moves downward, the packaging upper shell 106, the packaging lower shell 104 and the bottom surface of the transfer trough 102 form an enclosed space, and the packaging upper shell 106 is connected to a vacuum generating device through an air pipe; a sealing component 5 is arranged in the packaging upper shell 106, and the sealing component 5 is used to perform hot pressure sealing on the packaging bag.

[0045] In the embodiment of the present invention, when in use, a packaging bag containing low GI baked food is placed in the packaging lower shell 104 farthest from the support frame 105, and the bag mouth of the packaging bag is placed on the support rod 110. At this time, the flip mechanism 3 drives the transfer push plate 108 to rotate to a horizontal state and blocks the drop slot 107. The transfer push plate 108 holds the packaging bag, and the rotating mechanism 8 drives the station switching disk 103 to rotate, and the station switching disk 103 drives the four packaging lower shells 104 to rotate, so that the packaging lower shell 104 containing low GI baked food moves to the bottom of the packaging upper shell 106, and the lifting mechanism 6 drives the packaging The upper shell 106 is installed and moved downward, and the lower end of the upper shell 106 of the packaging is against the upper end of the lower shell 104 of the packaging, so that the upper shell 106 of the packaging, the lower shell 104 of the packaging and the bottom surface of the transfer sink 102 form a closed space, and the vacuum generating device draws vacuum into the upper shell 106 of the packaging through the air pipe, and then the packaging bag is vacuumed, and then the sealing component 5 performs hot pressure sealing on the packaging bag, and the vacuum generating device breaks the vacuum in the upper shell 106 of the packaging, and the upper shell 106 of the packaging, the lower shell 104 of the packaging and the bottom surface of the transfer sink 102 form a closed space to break the vacuum, and the lifting mechanism 6 drives the upper shell 106 of the packaging to move upward The rotating mechanism 8 drives the station switching disk 103 to rotate, and the station switching disk 103 drives the four packaging lower shells 104 to rotate, so that the packaging lower shell 104 containing the low GI baked food moves to above the drop hole 111. When the station switching disk 103 drives the packaging lower shell 104 to move above the drop hole 111, the flipping mechanism 3 drives the transfer push plate 108 to rotate downward and open the drop chute 107, and the vacuum-packed low GI baked food falls from the drop chute 107 and the drop hole 111, thereby realizing the automatic unloading of the vacuum-packed low GI baked food. The station switching disk 103 rotates, and the station switching disk 103 drives the four packaging lower shells 104 to rotate, so that the packaging lower shell 104 containing low GI baked food is away from the top of the blanking hole 111, and the flip mechanism 3 drives the transfer push plate 108 to rotate to a horizontal state and blocks the blanking slot 107. By switching the four packaging lower shells 104 stations, the feeding position of the vacuum packaging remains unchanged, which is convenient for feeding, and the GI baked food is automatically unloaded after vacuum packaging, avoiding manual unloading. Workers only need to load the materials, thereby reducing the labor intensity of workers and improving the efficiency of vacuum packaging of GI baked food.

[0056] The above embodiment of the present invention provides a vacuum packaging device for producing low GI baked food. When in use, a packaging bag containing low GI baked food is placed in the packaging lower shell 104 farthest from the support frame 105. Under the guiding action of the guide shaft 112, the elastic force of the compression spring 2 113 is overcome and the auxiliary pressure rod 109 is pulled upward to place the bag mouth of the packaging bag on the support rod 110.

The sliding push block 304 overcomes the elastic force of the tension spring 2 303 and pushes the transfer push plate 108 to a horizontal state. The transfer push plate 108 rotates upward, and the transfer push plate 108 drives the cam 402 to reverse and reset. The compression spring 2 113 pushes the auxiliary pressure rod 109 downward to reset the auxiliary pressure rod 109. By switching the four packaging lower shell 104 stations, the feeding position of the vacuum packaging remains unchanged, which is convenient for feeding. After the GI baked food is vacuum-packed, the material is automatically unloaded, avoiding manual unloading.
