The first half-tooth ring 14 controls the movement of the first displacement adjustment plate 13 through the first connecting rod 16 and the first docking shaft 15, so that the first displacement adjustment plate 13 and the second displacement adjustment plate 17 can rotate in the opposite direction, so that the food materials can be guided and discharged into the second weighing and separating mechanism 9 through the first displacement adjustment plate 13 and the second displacement adjustment plate 17. The structures of the first weighing and separating mechanism 7 and the second weighing and separating mechanism 9 are the same, and secondary control work is carried out. The support ring 23 is fixed to the import seat 5, and the support ring 23 is supported by the support vertical rod 24, which is convenient for fixing the weighing processing structure 1. The packaging bag carrier 26 is provided with a tube shaft, which can control the guiding and transmission of the packaging bag and introduce it into the packaging processing component 30 through the guiding roller 28. The food can reach the docking cone guide seat 27 through the docking guide block 25 and then be guided into the packaging bag. At this time, the packaging bag reaches the position between the first heating roller 34 and the second heating roller 35 through the guiding roller 28. At this time, the double-headed motor 38 controls the second tooth ring 37 to rotate. The second tooth ring 37 meshes with the first tooth ring 36, so that the first tooth ring 36 and the second tooth ring 37 rotate in the opposite direction, so that the first heating roller 34 and the second heating roller 35 also rotate in the opposite direction, thereby heating and sealing the two layers of packaging bags. Moreover, the double-headed motor 38 can drive the driving block 39 to rotate. The driving block 39 drives the cooperating tooth block 44 to rotate through the toothed belt 41, so that the third tooth ring 45 rotates. When the third tooth ring 45 rotates, it can drive the third tooth ring 45 at the left position to rotate in the opposite direction, so that the lower first heating roller 34 and the second heating roller 35 also rotate for secondary heating and sealing treatment. At the same time, when the first control guide rod 40 rotates, it can drive the second control guide rod 42 to follow and adjust, so that the adapter docking seat 43 performs limit telescopic adjustment under the action of the hydraulic telescopic rod. At this time, the telescopic rod 46 follows the problem and can drive the connecting rod 47 to rotate through the articulated connecting rod 48, and the rotation amplitude is controlled within 60 degrees.At this time, the connecting rod 47 can drive the rotation control rod 49 to move, so that the third heating roller 50 rotates accordingly. The two third heating rollers 50 come into contact to perform transverse hot extrusion work, thereby sealing the packaging bag and enabling continuous packaging production work to be completed.
