Four mounting shafts 20 are horizontally and rotatably mounted in the mounting column 4 through a bracket, and the axial direction of the mounting shafts 20 is consistent with the sliding direction of the square column 5. A second bevel gear 21 meshed with the first bevel gear 19 is fixedly arranged at the inner end of the mounting shaft 20, and a second gear 22 is fixedly arranged at the outer end of the mounting shaft 20. The inner end of the square column 5 is rotatably provided with a threaded rod 23 positioned inside the mounting column 4, and the inner end of the threaded rod 23 is fixedly provided with a gear column 24 which is coaxial with the threaded rod and is mutually meshed with the second gear 22. The axis of the threaded rod 23 is parallel to the axis of the mounting shaft 20, and the threaded rod 23 is in threaded rotation fit with the inside of the mounting column 4. The first bevel gear 19 is driven to rotate in the forward direction by rotating the rotating shaft 18 in the forward direction, and the second bevel gear 21, the mounting shaft 20 and the second gear 22 are driven to rotate by the first bevel gear 19. Second gear 22 rotates the in-process and drives gear post 24 and threaded rod 23 and rotate, and threaded rod 23 rotates the horizontal outside removal of process promotion square post 5 to ensure the horizontal synchronous motion of four rubber slabs 6, further make aseptic plastic packaging box primary processing article can reach the state coaxial with erection column 4. The first bevel gear 19 is driven to rotate reversely by the reverse rotation rotating shaft 18, the square column 5 is driven to move horizontally inwards, and the horizontal support of the primary processed product of the sterile plastic packaging box is removed.
In this embodiment, the bottom end of the rotating shaft 18 is fixedly connected with a second lead screw 25 coaxial therewith, the lower surface of the gear plate 3 is vertically and fixedly provided with a limiting rod 26 around the second lead screw 25, and the limiting rod 26 is vertically and slidably fitted with a mounting block 27. The second lead screw 25 extends through the mounting block 27 and is in threaded rotational engagement with the mounting block 27. Four air grooves 28 which are communicated up and down are uniformly formed in the gear disc 3 along the circumferential direction of the gear disc, the middle parts of the air grooves 28 are horizontal, and the middle parts of the air grooves 28 are horizontally matched with an iron sealing block 29 in a sliding manner. The magnet piece 30 is installed along the horizontal slidable of air duct 28 middle part direction to the lower surface of toothed disc 3, and leading wheel 31 is installed through the support to the lower surface of toothed disc 3, and the one end of fixed connection haulage rope 32 on the magnet piece 30, the other end of haulage rope 32 is fixed connection on installation piece 27 behind leading wheel 31. A supporting block 33 is fixedly arranged on the lower surface of the gear plate 3, and a spring 34 is horizontally arranged between the supporting block 33 and the magnet block 30 along the sliding direction of the magnet block 30. When the rotating shaft 18 is rotated in the forward direction, the second lead screw 25 synchronously rotates in the forward direction, so that the mounting block 27 is driven to move vertically downwards along the limiting rod 26, and the magnet block 30 is pulled to slide inwards through the traction rope 32. When the magnet block 30 slides inward, the seal block 29 is moved by magnetic force to slide horizontally inward along the air groove 28, thereby stretching the spring 34. The inside atmospheric pressure of aseptic plastic packaging box primary processing article has been reduced to the inboard slip in-process along the gas tank 28 level to sealing block 29 for the inside atmospheric pressure of aseptic plastic packaging box primary processing article is less than external atmospheric pressure, supports aseptic plastic packaging box primary processing article through the atmospheric pressure effect and presses at the toothed disc 3 upper surface, has further avoided the piece of the in-process of polishing to get into inside aseptic plastic packaging box primary processing article. After cutting and polishing are finished, the second lead screw 25 is rotated reversely to drive the mounting block 27 to move vertically upwards, the magnet block 30 is pulled to slide outwards by the elastic force of the spring 34, and the sealing block 29 is driven to slide outwards horizontally along the air groove 28 by the magnetic force when the magnet block 30 slides outwards. The sealing block 29 has increased the inside atmospheric pressure of aseptic plastic packaging box primary processing article along the horizontal outside slip in-process of air duct 28 for the inside atmospheric pressure of aseptic plastic packaging box primary processing article resumes to initial numerical value, thereby has contacted the pressure effect and has compressed tightly the effect to aseptic plastic packaging box primary processing article.
