Abstract

The utility model relates to a collective monolayer color film packing and conveying device. The machine frame of the packing machine is equipped with an upper contracting packing film and a lower contracting packing film, and the machine table is connected with the conveying belt and is equipped with a feeding structure, a feeding device, a sealing and cutting knife and a shrinker in turn. The packing film is equipped with an opposite fixing plate on the machine frame, and the bottom of the fixing plate is equipped with a lifting rod for the revolving of the packing film. The side of the lifting rod is equipped with an inching switch. The machine frame is equipped with an inducer relative to the packing film track. The bottom of the packing film is engaged by the conveying roller under the machine frame and pulled in a single direction. As a consequence, the utility model can avoid the repetitive packing and promote the packing benefit.

Description

Individual layer colour film collective packing film feeder

The utility model relates to a kind of individual layer colour film collective packing film feeder, especially refers to a kind ofly coat collective's article, the cuff formula wrapping machine film feeder of shrink wrapping by the individual layer colour film.

Press, as shown in Figure 1, 2, commonly use cuff formula collective wrapping machine 1 and establish upper and lower shrink wrap 2 in frame, and collective's article 3 of being packed are subjected to delivery system 4 to deliver to board when location, mat air cylinder 5 is with piston rod, with these collective's article 3, as beer, beverage etc., push to the board other end, and use support and draw shrink wrap 2 to coat collective's article 3, then, infeed the thermal contraction machine shrink wrapping after cutting with sealing cutter envelope.

But, packed collective's article 3 propelling movement stroke places by upper and lower two relative packing shrink films 2 in board and linked mutually, then, cut packing shrink film 2 with the sealing cutter envelope again, so will produce the following shortcoming of promptly depositing:

One: after the each envelope of sealing cutter is cut, to make packing shrink film 2 produce involution and connect face, the seam that hot melt engages, so produce forward and backward twice seam when being coated on collective's article 3, and with thermal contraction, to this seam line be represented on the collective's article 3 after the packing, have a strong impact on packing aesthetic feeling benefit.

Its two: upper and lower two relative shrink wrap 2 is wayward for film length in each coating stroke, cause the coated length inequality of upper and lower shrink wrap 2, therefore, shrink wrap 2 is only limited to and uses the vegetarian noodles monochrome, be unsuitable for the colored printing pattern, do not show for packing visual sense and identification sign property.

Primary and foremost purpose of the present utility model is to provide a kind of individual layer colour film collective packing film feeder, by the technological means of individual layer for film, the accurate control for the film stroke is provided, be beneficial to the colored printing identification on the shrink wrap, and can reduce the involution seam, promote the packing benefit.

A time purpose of the present utility model is to provide a kind of individual layer colour film collective packing film feeder, establishing inductor by shrink wrap side seal detects a little, induction control board below film drawing device for inductor, after coating envelope is each time cut, film drawing device promptly toward the drop-down shrink wrap of holding up to one stroke, and reach the correction usefulness of joint close is drop-down and each stroke.

The purpose of this utility model is achieved in that a kind of individual layer colour film collective packing film feeder, the frame of wrapping machine is provided with upper and lower shrink wrap, and connect load-transfer device on the board, also on board, be provided with feeding structure, pay-off, sealing cutter and shrinker in regular turn, it is characterized in that: this packaging film is provided with the relative fixed plate in frame, the adapter plate bottom be provided with for packaging film wear around portable bar, and be provided with micro-switch and with respect to the packaging film track in this portable bar side, and the packaging film bottom is held up by the conveying roller engagement and unidirectional the drawing of frame below.

The sealing cutter counterdie side that this packaging film places is provided with an air pipe.

Owing to adopt such scheme: avoid repeated packing, promote the packing benefit.

See also shown in Figure 3, the utility model collective wrapping machine 10 is provided with feeding structure 11 in an end, and to infeed collective's article 110 quantitative then, as 6 bottles, 12 bottles etc., collective sends to pay-off 20, pull over by pay-off 20 again, and coat collective's article 110 with shrink wrap 3 00, and then, send into thermal contraction machine 500 shrink wrappings after cutting with sealing cutter 400 envelopes.

Shown in Fig. 4 to 7, holding up upright frame 15 is provided with sealing cutter 400 device front side top extension one supports 31 and fixes packaging film volume 301, drive with conveying roller 32 engagements that driven by motor 33 again, yet, frame 15 front sides are provided with relative fixed frame 34 and are provided with micro-switch 35 and portable bar 36, make packaging film 300 drawn by collective's article 110 and hold up when coating, pulling portable bar 36 promotes and breaks away from micro-switch 35, starter motor 33 drives conveying roller 32 and conveying and packaging film 300 is supplied with a predetermined length, promptly coats collective's article 110 required packaging film 300 length; In addition, packaging film 300 other ends of frame 15 belows are done unidirectional drawing by motor 38 driving conveying rollers 39 and are held up conveying; So collective's article 110 are sent into by load-transfer device 26, and pull on dull and stereotyped 27, pay-off separate case is filed an application, and then, enclose around these collective's article 110 peripheries by packaging film 300, and work as sealing cutter 400 with these packaging film 300 involutions, after the cut-out, packaging film 300 produces a seam 305, as shown in Figure 7, motor 38 drives conveying rollers 39 at this moment, packaging film 300 is detected a little 302 toward drop-down holding up to packaging film 300 sides, as shown in Figure 8, be subjected to till inductor 37 is responded on the frame 15, and make packaging film 300 reply normal tightness, for the coating packing of next stroke; Also the envelope cut-grafting seam 305 of packaging film 300 can be pulled down, make the seam 305 of the not residual lastrow journey of coating of next stroke, and can coat envelope each time and all have the corrective action of packaging film 300 when cutting, with the pattern sign that provides packaging film 300 surface colors to print, all be the location and be packaged in collective's article 110 same positions, promote the packing benefit.

And then, place the seam place in the packaging film 300 of load-transfer device 26 front ends dull and stereotyped 27 and 400 times intermodes of sealing cutter and can be provided with an air pipe 270, feed is gone into the envelope cut-grafting seam 305 that air blows packaging film 300, quicken its rate of cooling, hold up not loose splitting to guarantee to draw, and between the feedway of sealing cutter bed die and thermal shrinking package machine, establish and be connected load-transfer device 261, use constant speed collective's article 110 are sent into shrink wrapping, coat the tram non-migration of collective's article 110 to keep packaging film 300.

According to last, the utility model is supplied with the technological means of packaging film 300 by individual layer, provides that to coat stroke accurate, can supply printed color pattern or sign, and the benefit attractive in appearance of minimizing seam, all has a usability on progressive and the industry, earnestly asks an ancient unit of weight office explicit example for reference, the favour quasi patent.
