The working principle is as follows: the plastic raw materials to be processed and degraded are added into the extruder 51 through the feeding hopper 53, in the feeding process, as the interior of the plastic raw materials is doped with metal materials, the rotating chassis 531 is opened at this time, the internal steel balls 5312 interact with the rotating inner ring 5313 to drive the rotating outer ring 5311 to rotate, so as to ensure that the adsorption disc 532 rotates at a constant speed, the internal iron sucking rod 537 is driven to rotate in the feeding bin 533 in an all-around manner, the iron sucking rod 537 contacts with the added plastic raw materials in the rotating process, so as to adsorb the metal impurities in the plastic raw materials, the plastic raw materials enter the processing box 52 through the screen 534, are primarily processed through the processing box 52, then are conveyed into the tank 22 through the feed valve 45 and the lead-in valve 44 to be blown into the film, the film cavity is heated by the external heating equipment in the tank 22 to gradually melt the plastic raw materials, after the molten plastic is cooled by the blowing cavity 27 and is blown and cooled, the cooling liquid is added into the liquid adding hole 261, the condensing pipe 263 in the condensing cavity 262 enables the die head 26 to be in a condensing state, the cooling efficiency of the plastic molten film is accelerated, the plastic molten film is blown to pass through the herringbone plate 25 and is finally conveyed outwards by the traction roller 31;
in the process that the plastic raw material passes through the screen 534, because the surface of the screen 534 is also provided with the magnetic paste, metal impurities on the surface of the plastic raw material are further adsorbed, at the moment, the iron-pulling block 538 can be pulled, the iron-pulling rod 537 can pass through the extraction cavity 5364 in the movable hole 536, the metal scraper 5363 on the surface of the movable surface 5361 can scrape off the metal impurities adsorbed on the surface of the iron-pulling rod 537 while the iron-pulling rod 537 is extracted, the scraped metal materials can fall into the discharge bin 533, a lot of metal impurities exist on the surface of the screen 534, the movable pull tabs 535 at two ends of the screen 534 are pulled, the screen 534 is pulled out of the discharge bin 533, and the metal impurities are concentrated;
the film 33 after the film blowing treatment is conveyed to the surface of the conveying roller 34 through the traction roller 31, the winding roller 35 is used for winding, the hydraulic cylinder 362 is opened in the winding process of the winding roller 35, the flattening rod 363 is driven to move back and forth, and the flattening rod 363 can flatten the film 33 on the surface of the winding roller 35 due to the fact that the radian of the flattening rod 363 is consistent with that of the surface of the winding roller 35, folds on the surface are paved, and the processing effect of the film 33 is guaranteed.
In the above scheme, the iron absorbing rod 537 is matched with the adsorption disc 532, so that the problem that when the existing film blowing mechanism 2 is used and large quantities of plastic particles are poured into the hopper at one time, metal impurities doped in the plastic particles are difficult to be processed in time and can be mixed in the plastic master batches to affect the production quality of the master batches is solved, when the rotary base disc 531 is opened, the internal steel balls 5312 interact with the rotary inner ring 5313 to drive the rotary outer ring 5311 to rotate, so that the adsorption disc 532 is ensured to rotate at a constant speed, the internal iron absorbing rod 537 is driven to rotate in the discharge bin 533 in an all-around manner, and in the rotating process of the iron absorbing rod 537, the iron absorbing rod can contact with the added plastic raw materials, so that the metal impurities in the plastic raw materials can be adsorbed, and the purity of the master batch raw materials is ensured; the screen 534 is matched with the metal scraper 5363, so that the problem that metal impurities in master batch raw materials are difficult to treat is solved, in the process that plastic raw materials pass through the screen 534, as the surface of the screen 534 is also provided with the magnetic paste, the metal impurities on the surface of the plastic raw materials are further adsorbed, at the moment, the iron pulling block 538 can be pulled, the iron absorbing rod 537 can pass through the pulling cavity 5364 in the movable hole 536, the metal scraper 5363 on the surface of the movable surface 5361 can scrape the metal impurities adsorbed on the surface of the iron absorbing rod 537 while the iron absorbing rod 537 is pulled out, the scraped metal materials can fall into the discharging bin 533, so that a lot of metal impurities exist on the surface of the screen 534, the movable pull tabs 535 at two ends of the screen 534 are pulled, the screen 534 is pulled out of the discharging bin 533, the metal impurities are intensively treated, and the working efficiency is improved; the cooperation of wind-up roll 35 and flattening stick 363, the in-process of having avoided current blown film mechanism 2 to use, the processing of can't flattening in the surface of rolling plastic film 33, there is the fold in film 33 surface, be difficult to guarantee processingquality's problem, film 33 after carrying out blown film processing passes through carry out the surface to transfer roller 34 through carry out the carry-over pinch rolls 31, roll through wind-up roll 35 at last, at the in-process that wind-up roll 35 carries out the rolling, open pneumatic cylinder 362, then drive the push rod seesaw, flattening stick 363 links along with the push rod, because flattening stick 363's radian is unanimous with the radian on wind-up roll 35 surface, flattening stick 363 can flatten the processing with the film 33 on wind-up roll 35 surface, lay the fold on surface, the machining effect of film 33 has been guaranteed, the practicality of device has been improved.
