Top electrode 341 is pressed to from the top position using middle packaging film 811 by bottom electrode 342 by electrode drive mechanism, So that Top electrode 341 is separated by packaging film 811 with bottom electrode 342 in use, and Top electrode 341 and bottom electrode 342 are guaranteeing to make With middle packaging film 811 can normal through on the premise of to having certain clamping force using middle packaging film 811, now, due to upper Electrode 341 is off in electrical characteristic with bottom electrode 342, and the control device of film-wrapping machine receives the off-state letter Number, i.e., can judge that packaging film 811 is not run out in use；When in use, 811 rear of packaging film is pulled by film-wrapping machine 9, depart from After the clamping of Top electrode 341 and bottom electrode 342, Top electrode 341 is no longer used middle packaging film 811 with bottom electrode 342 and separates, Now, due to Top electrode 341 and bottom electrode 342 in electrical characteristic in an ON state, master controller receives the connection shape State signal, i.e., can judge that packaging film roll 81 has been used up in use.Also, master controller can pass through coordination electrode driving machine Top electrode 341 is removed from bottom electrode 342 by structure, so as to control packaging film testing agency 3 to stop detection；And in Tui Mo mechanism 7 After promoting packaging film roll 82 to be replaced to be rolled on the first station 2A, packed, by be replaced, the packaging to be replaced that film roll 82 is unreeled out Film 821 is pulled the interstitial site reached between Top electrode 341 and bottom electrode 342, and now, master controller can be by controlling electricity Pole drive mechanism is pressed in Top electrode 341 on bottom electrode 342 again so that packaging film to be replaced 821 is by Top electrode 341 and lower electricity Pole 342 separates, so that packaging film testing agency 3 re-starts detection.

Referring to Fig. 4, above-mentioned buffer gear 5 is provided with front transition rotating shaft 51, buffering rotating shaft 52, rear transition rotating shaft 53 and skate machine Structure 54；Front transition rotating shaft 51, buffering rotating shaft 52 and rear transition rotating shaft 53 are sequentially arranged and they by rear to front in the horizontal direction Shaft axis be all horizontally disposed with and be parallel to each other, buffering rotating shaft 52 is by vertically free skating on the slide mechanism 54 Dynamic；Film device 4 is connect through hot melten type and connect packaging film 811 in the use after film mouth 4a and through the mode of buffer gear 5 be：Successively from The top at the top of front transition rotating shaft 51, the bottom of buffering rotating shaft 52 and rear transition rotating shaft 53 passes through.

Referring to Figure 13 and Figure 14, above-mentioned auxiliary film placing mechanism 6 mainly includes film head stationary fixture and guide rail, and guide rail is fixed on Above-mentioned frame 1 is internal and extends along the longitudinal direction, and film head stationary fixture on guide rail and can connect film location along guide rail And put between film location and move, connect that film location i.e. hot melten type connects film device 4 meets film mouth 4a, puts the film location i.e. rear end face of frame 1 Position, the film head 8211 of packaging film to be replaced 821 can be installed on film head stationary fixture.

The film head stationary fixture of film to be put is hot melten type from narrow thermal welding film station using guide rail by the utility model Connect film device 4 connects film mouth 4a removal, film head stationary fixture is placed in openr, it is easy to which what film was put in operation puts film location, can Simplify and membrane operations are put, improve and put membrane efficiency.

Above-mentioned film head stationary fixture includes base plate 61 and press mold component 62, and press mold component 62 is arranged on 61 upper surface of base plate, Coordinate the film head 8211 for clamping packaging film to be replaced 821 with base plate 61.

Wherein, base plate 61 may be selected shaggy friction base plate, be the abjection of the film head 8211 of packaging film to be replaced 821 Bigger resistance is provided.

Above-mentioned press mold component 62 includes fixed block 21, gravity rod 622, hinge plate 623 and hinge 624, and gravity rod 622 laterally sets On bottom set plate 61, specially：622 two ends of gravity rod connect a hinge plate 623 respectively, and the other end of two hinge plates 623 passes through hinge 624 It is articulated with the side of two fixed blocks 21 being fixed on base plate 61.

The utility model relies on the film head 8211 of the deadweight fixation of gravity rod 622 packaging film 821 to be replaced.

622 two ends of above-mentioned gravity rod are by unilateral bearing 625 on hinge plate 623.When putting film, 625 turns of unilateral bearing Enter direction to film head depth, easily film head is put into so as to the rotation along bearing 25.And the one-directional rotation of unilateral bearing 625 is special Property, can be the larger resistance of offer that comes off of the film head 8211 of packaging film to be replaced 821 again, prevent the film of packaging film to be replaced 821 8211 come off under deadweight.

Above-mentioned auxiliary film placing mechanism 6 arranges two guide rails, and they be arranged in parallel.Guide rail is by slide block 641 and 642 structure of track Become, specifically constitute by linear bearing and as the cylinder axis of track.Wherein, the two ends of track 642 are designed with for guide rails assembling Hold-down support 643, and two ends further respectively have magnet 644.

Above-mentioned base plate 61 is connected with slide block 641, across on two tracks 642, and make press mold component 62 be located at two tracks 1 it Between.Auxiliary film placing mechanism also includes for pulling out base plate 61 along track 642, to put the handle 65 of film.Handle 65 by The rod of one bending is constituted, and the two ends of rod are connected with the both sides of base plate 61, forms an annular element with base plate 61, the annular element Interior annular distance constituted membrane channels.The structure of handle 65 is compared to the hand for arranging shape such as 642 structure of track in 61 both sides of base plate For pull handle, be conducive to the pull-out of user's one-handed performance or propulsion base plate 61.Handle 65 is with base plate 61 generally within same parallel In the plane of two tracks, preferably to adapt to the narrow thermal welding film station of vertical direction spatial.

The course of action of above-mentioned auxiliary film placing mechanism 6 is：

When film is put, base plate 61 is pulled out by handle 65, base plate 61 is made along track 642 from the narrow thermal welding of vertical direction spatial Skid off in film station, when 641 adhesive in rail of slide block, 642 outer end is on the magnet 644 of rearward end, film head stationary fixture is reached relatively Film station is put for open, now, the film head 8211 of the packaging film to be replaced 821 that puts in order is hauled both sides are exceptionally straight to fill in gravity Under bar 622, it is readily achieved and puts membrane operations；After completing to put film, in the bag to be replaced that will be fixed by press mold component 62 along track 642 The film head 8211 of dress film 821 advances the setting position of thermal welding film station, and 641 adhesive in rail of slide block, 642 inner end is leading section Magnet 644 on, film head stationary fixture returns to space-constrained and connects film location, waits film waiting.642 inner end of track be leading section also Detection switch 5 is fixed with, after film head stationary fixture reaches and connects film location, is sent a signal to hot melten type and film device 4 is connect, to notify Which can start to connect membrane operations.

The utility model is not limited to above-mentioned specific embodiment, according to the above, according to the ordinary skill of this area Knowledge and customary means, under the premise of without departing from the above-mentioned basic fundamental thought of the utility model, the utility model can also be made The equivalent modifications of other various ways, replacement or change, all fall among protection domain of the present utility model.
