Meanwhile, when the corrugated tube assembly body 11 moves to a position between the two shaping rollers 2, the two rotating plates 33 can be controlled to drive the two moving plates 13 to move towards the direction of approaching each other, and the moving plates 13 are pushed to move upwards to a position abutting against the bottom of the corrugated tube assembly body 11 through upward extension of the telescopic ends of the two second electric telescopic rods 34, so that the corrugated tube assembly body 11 keeps a horizontal straight line state in the process of entering the box body 1 and waiting for the two shaping rollers 2 to shape the corrugated tube assembly body; after one section of the bellows assembly body 11 enters the inside of the box body 1, the two clamping plates 28 at the moment are in the state shown in fig. 8, redundant cutting oil can accumulate in the groove 29, at the moment, the telescopic end of the first electric telescopic rod 27 located at the right end can be controlled to stretch upwards, the lower clamping plate 28 is pushed to be in an inclined state upwards, the redundant cutting oil collected in the groove 29 flows downwards to the inside of the rectangular through groove 17 from the low end, the redundant cutting oil is filtered by the gauze 19 arranged at the bottom of the box body 1 and then falls into the collecting box 4 to be collected, then the telescopic end of the first electric telescopic rod 27 is retracted upwards to reset, the telescopic ends of the plurality of first electric telescopic rods 27 are controlled to stretch together, and the two clamping plates 28 are driven to move towards the direction close to each other again, so that the subsequent part to be shaped of the bellows assembly body 11 is shaped and the cutting oil is smeared.
After one section of the corrugated pipe assembly body 11 moves to a position between the two shaping rollers 2, the double-headed screw rod 22 is controlled to rotate to drive the two shaping rollers 2 to move towards the direction of approaching to each other until the corrugations of the outer walls of the two shaping rollers 2 are in one-to-one correspondence with the corrugations of the outer walls of the corrugated pipe assembly body 11, the two shaping rollers 2 are controlled to rotate towards the opposite direction, and rolling shaping treatment is carried out on the outer walls of the corrugated pipe assembly body 11, so that the compressive stress of the corrugated pipe assembly body 11 is increased, and the service life of the corrugated pipe assembly body 11 is prolonged.
After the rolling shaping work of the two shaping rollers 2 on the corrugated pipe assembly body 11 is completed, a small amount of cutting oil and scraps generated by rolling shaping exist on the surface of the corrugated pipe assembly body 11, and as the top ends of the two moving plates 13 are all abutted against the outer wall of the corrugated pipe assembly body 11, the expansion ends of the plurality of first electric expansion rods 27 can be controlled to stretch to drive the two clamping plates 28 to clamp and fix the corrugated pipe assembly body 11, and then the driving motor 9 is controlled to slowly drive the first gear 23 to rotate, so that the third gear 7 and the mounting plate 6 can be driven to synchronously rotate, the mounting plate 6 can drive the corrugated pipe assembly body 11 to rotate by a certain angle through the two clamping plates 28, so that a small amount of cutting oil and scraps existing on the outer wall of the corrugated pipe assembly body 11 in the rotation process can be scraped to the top of the gauze 19 in the friction process with the top of the moving plates 13, and the surface of the corrugated pipe assembly body 11 is convenient to clean.
After taking out the bellows subassembly body 11 from the inside of box 1, control two rotor plates 33 drive two movable plates 13 and rotate to be the state that is shown in fig. 6 towards mutual direction of keeping away from, the one end that two movable plates 13 kept away from rotor plate 33 is in contact with the outer wall of corresponding plastic roller 2 respectively this moment, through controlling two plastic rollers 2 slowly to rotate again for two plastic rollers 2 respectively with the top butt friction of two movable plates 13, make cutting oil and the piece on two plastic roller 2 surfaces can be scraped to the smooth outer wall of two movable plates 13 side that is close to mutually, and guide it to the top of gauze 19, collect the cutting oil filtration in the inside of collecting box 4, the piece can remain at gauze 19 top.
Because after the smooth outer wall of the side, which is close to the two moving plates 13, guides the cutting oil and the chips, part of the cutting oil and the chips are attached to the outer wall of the side, which is close to the two moving plates 13, at this time, the two mounting seats 12 can be controlled to move in the direction away from each other, so that the rectangular through groove 17 is completely exposed, the two rotating plates 33 are controlled to rotate downwards in the direction away from each other to form a horizontal state, the smooth outer wall of the two moving plates 13 is flush with the inner bottom surface of the box body 1, and finally the two mounting seats 12 are controlled to move in the direction close to each other, so that the bottoms of the two mounting seats 12 can scrape the cutting oil and the chips attached to the smooth outer walls of the tops of the two moving plates 13, and the cleanliness of the smooth outer walls of the two moving plates 13 is improved.
And still have part attached to gauze 19 after the filtration of cutting oil through gauze 19, this moment steerable a plurality of first sliders 20 drive two movable rods 10 towards each other near the direction and the butt in the inside of two first spouts 16, make originally be the gauze 19 of tiling expansion state and can buckle and fold down, then control two rotation plates 33 all rotate down and be after the vertical state, make two movable plates 13 keep away from scraper blade 32 of one side and lie in two movable plates 13 and be close to one side mutually after rotating, and with the gauze 19 butt of fold down state, make the gauze 19 of fold state be located between two scraper blades 32, through controlling the extension of the flexible end of second electric telescopic rod 34 upwards, drive two movable plates 13 all move down after, can drive two scraper blades 32 with the situation and scrape down the cutting oil that the gauze 19 is inside adsorbed, make gauze 19 top only leave the piece, avoid the waste of cutting oil.
After cutting oil and scraps on the outer walls of the two shaping rollers 2 are scraped and cleaned through the tops of the two moving plates 13, a small amount of grease still remains on the outer walls of the two shaping rollers 2, at the moment, the output end of the external infusion mechanism is communicated with the connecting end 30 of the two moving plates 13, so that cleaning fluid in the external infusion mechanism can be led into the two moving plates 13, the two rotating plates 33 are controlled to rotate towards the approaching direction to each other to be in a vertical state, the telescopic ends of the second electric telescopic rods 34 are controlled to extend upwards to drive the two moving plates 13 to move upwards to the position close to the shaping rollers 2, the two shaping rollers 2 are driven to move towards the approaching direction to each other through the double-headed screw rod 22 until the two shaping rollers 2 are respectively abutted against the cleaning brushes 31 on the outer walls of the two moving plates 13, then, two second sliding blocks 21 in the two second sliding grooves are controlled to drive the gauze 19 to move to a position far away from the rectangular through groove 17, the other two second sliding blocks 21 drive the plastic cloth 18 to move to a position right below the rectangular through groove 17, at the moment, the plastic cloth 18 right below the rectangular through groove 17 can seal the rectangular through groove 17 and protect the lower collecting box 4, a plurality of liquid discharge ports on one side, far away from the two moving plates 13, of the two moving plates are controlled to discharge cleaning liquid to the surfaces of the two shaping rollers 2, the two shaping rollers 2 are controlled to rotate and rub against the cleaning brush 31, grease on the surfaces of the shaping rollers 2 can be cleaned by means of the cleaning brush 31 and the cleaning liquid, waste liquid generated by cleaning falls down to the top of the plastic cloth 18 through the rectangular through groove 17 and is blocked, and the waste liquid is prevented from polluting cutting oil collected by filtering in the collecting box 4.
