Implementation principle of the present invention is as follows:

When carrying out using wrap-up, by four stabilizer blades 1 respectively according on the side of main body 10 bottom four, two are received Drum 5 locks the both ends for being mounted on rotary shaft 3, and rotary shaft 3 is mutually chimeric with motor 6, manipulates 7 driving motor 6 of electric cabinet, motor 6 Rotary shaft 3 is driven to be rotated, electric cabinet 7 controls three wind-up rolls 9 and rotary shaft 3 is assisted to carry out winding freshness protection package.

In winding, collet 452 is adjusted, the inwardly activity of fixture block 4521 is driven by telescopic rod 4525, with two elasticity members Paper tube 43 is clamped connection and is transported to inside delivery chute 455 by part 4522, is adjusted by adjustable plate 453 according to the diameter of paper tube 43 The distance between whole two pieces of slide strips 451, paper tube 43 is put into inside delivery chute 455, by slide strips 451 and sliding rail 454 by paper tube 43 are transported to inside rotary shaft 3, by paper tube 43 be adjusted to using position on, adjust two pieces of limit plates 42, rotate turning rod 47 Rotor magnet 46, the principle mutually attracted using the different machine magnetic pole of magnet 46, magnet 46 will carry out on the inside of two pieces of limit plate 42 phases it is attracting, Paper tube 43 is fixedly clamped on the position used, prevents paper tube 43 from occurring offset phenomena when winding work, reduces work people The labor intensity of member, can be improved the winding efficiency of freshness protection package.

When being wound, freshness protection package is rolled on the levelling device 2 on wind-up roll 9, rubber pad 234 and freshness protection package are mutual Friction generates electrostatic and is adjusted between two pieces of pulling plates 233 so that freshness protection package is attached on wind-up roll 9 according to the width of freshness protection package Distance, sliding block 235 drive two pieces of pulling plates 233 be adjusted fixation on movable plate 231, freshness protection package is carried out with pulling plate 233 Flattening, is connected to 234 bottom of rubber pad for air inlet 24, air inlet 24 is connected in air inlet pipe 22, and air inlet pipe 22, which runs through, stretches Enter inside suction chamber 26, pushes push plate 265, entrance 266 is mutually chimeric with treatment trough 262, drive the air draught inside air draught chamber 264 Machine siphons away the air of freshness protection package lower end, so that freshness protection package and wind-up roll 9 fit closely together, the air after sucking is led to It crosses interface 2622 to be flowed into inside separation partition 2623, the impurity dust in air and air is subjected to separating treatment, prevents from growing Time uses, and air draught chamber 264 is caused to be blocked by the impurity dust in air, then uses 2624 purified treatment of purifying board, passes through four Air moment around freshness protection package is drawn into air draught chamber 264 by a air inlet 24, allows freshness protection package by four 24 winks of air inlet Between even up winding after winding processing is carried out on being transmitted to paper tube 43, by pulling plate 233 and air inlet 24 work in coordination reduction protect The buckling phenomena occurred in fresh bag wrapup procedure improves the flatness on freshness protection package surface, accelerates subsequent freshness protection package packaging processing work Make.

Problems solved by the invention is to solve existing freshness protection package when starting to be wound, can not will be inside freshness protection package Paper tube is fixed on the position of winding, and paper tube is caused offset phenomena occur, is needed artificial adjustment in real time, is increased the labor of staff Fatigue resistance, and reduce the winding efficiency of freshness protection package；And freshness protection package is in tensioned state between wind-up roll, the guarantor of wrinkle will occurs Fresh bag is involved in paper tube, and buckling phenomena can all be occurred by causing to overlap the freshness protection package surface for being involved in paper tube later, finally influences freshness protection package The flatness on surface influences subsequent freshness protection package packaging processing work.The present invention is combined with each other by above-mentioned component, makes the present invention It is able to achieve, by using the principle that the different machine magnetic pole of magnet mutually attracts, will carry out on the inside of two pieces of limit plate phases attracting, paper tube is clamped It is fixed on the position used, prevents paper tube from offset phenomena occur, reduce the labor intensity of staff, and improve freshness protection package Wind efficiency；It is worked in coordination again by pulling plate and air inlet and flattens freshness protection package, reduce the pleat that freshness protection package occurs in wrapup procedure Wrinkle phenomenon, improves the flatness on freshness protection package surface, accelerates subsequent freshness protection package packaging processing work.
