Summary of the invention
The object of the invention is the deficiency of at least one overcome described in above-mentioned prior art, propose a kind of tubular membrane bulging mechanism that tubular packaging film bulging is stable that can ensure.
In order to achieve the above object, the technical scheme that the present invention takes: a kind of tubular membrane bulging mechanism, comprises bracket, swollen bagging apparatus, swollen bagging apparatus is placed on bracket, described swollen bagging apparatus comprises pedestal and bag opening mechanism, and bag opening mechanism is arranged on pedestal, and pedestal is connected by magnetic force and bracket are attracting.
Said base is provided with the first roller, and the position of bracket set by corresponding first roller is provided with the second roller, and the first roller can be tangent with the second roller, and in working process, under the attraction of magnetic force, the first roller is tangent with the second roller all the time.
Further, above-mentioned bracket is provided with the first magnet, and the position of pedestal set by corresponding first magnet is provided with the second magnet, and the first magnet can be attracting with the second magnet.
Further, above-mentioned first magnet is positioned at the middle part of bracket, and the second magnet is positioned at the middle part of pedestal.
Above-mentioned bag opening mechanism is umbrella mechanism, and bag opening mechanism is arranged on pedestal wherein one end, and the other end of pedestal is provided with distending frame, packaging film first by distending frame distending, and then by bag opening mechanism strut for.
Above-mentioned distending frame is Eight characters structure.
Above-mentioned tubular membrane bulging mechanism also includes bracket, and bracket is arranged on bracket.
Above-mentioned bracket is also provided with leads film roller, and leads one end that film roller is arranged on bracket, and bracket is arranged on the other end of bracket, and packaging film is being led under film roller guides and can entered into swollen bagging apparatus smoothly.
Conveniently move, above-mentioned tubular membrane bulging mechanism also comprises travelling car, and bracket is arranged on travelling car.
Above-mentioned travelling car being also provided with the bracing frame for placing tubular packaging film volume, stand-by tubular packaging film volume being placed on bracing frame, can realizing continuously for packaging film.
Swollen bagging apparatus of the present invention attracts to be connected with bracket owing to adopting magnetic force, makes the first roller on pedestal keep tangent with the second roller of bracket all the time.During use, first swollen bagging apparatus is put into tubular packaging film, then swollen bagging apparatus is placed on bracket, the first roller and the second roller tangent, under the magnetic interaction of first and second magnet, make swollen bagging apparatus be positioned in certain scope, when clamper pulls packaging film to move, the first roller and the second roller rotate, direction is contrary, packaging film first by front end distending frame distending, and then is strutted by the bag opening mechanism of the other end, and now packaging film is tubular.After clamper mantle terminates, cutter cuts off packaging film, and because also continuing inside packaging film to be strutted by bag opening mechanism after cut-out packaging film, therefore the mouth of packaging film opens all the time, clips for clamper returns the step that packaging film provides key.

Detailed description of the invention
Embodiment
The structure of tubular membrane bulging mechanism of the present invention as shown in Figure 1, 2, comprises bracket 1, swollen bagging apparatus 2, leads film roller 3, travelling car 4 and bracing frame 5.Wherein bracing frame 5 is arranged on travelling car 4, for placing stand-by tubular packaging film volume, bracket 1 is arranged on travelling car 4 by bracket 6, and bracket 1 is positioned at the tail end of bracket 6, swollen bagging apparatus 2 is placed on bracket 1, leads the front end that film roller 3 is arranged on bracket 6.Described swollen bagging apparatus 2 comprises pedestal 21, bag opening mechanism 22 and distending frame 25, bag opening mechanism 22 is arranged on the tail end of pedestal 21, distending frame 25 is arranged on the front end of pedestal 21, the bottom of pedestal 21 is provided with four the first rollers 23, four the first rollers 23 lay respectively at the position of bottom near four angles of pedestal 21, position set by first roller 23 of described bracket 1 bottom corresponding pedestal 21 be respectively equipped with the second roller 11, first roller 23 and the second roller 11 tangent; Described bracket 1 is provided with the first magnet 12, and the position of pedestal 21 set by the first magnet 12 of corresponding bracket 1 is provided with the second magnet 24, first magnet 12 can be attracting with the second magnet 24, as shown in Figure 3,4.
In the present embodiment, above-mentioned first magnet 12 is positioned at the middle part of bracket 1, and the second magnet 24 is positioned at the middle part of pedestal 21.Above-mentioned bag opening mechanism 22 is umbrella mechanism, and the length of every bar support rib 221 of bag opening mechanism 22 is equal, and the distance of the center shaft 222 of the end of support rib 221 and bag opening mechanism 22 is adjustable, so that is suitable for and carries out bulging to the packaging film of varying cross-section size.Above-mentioned distending frame 25 is formed primarily of two connecting rods 251, in Eight characters structure, by the slide block 253 on mobile slide bar 252, the angle between two connecting rods 251 can be changed, cause the distance of change two connecting rod 251 ends, to be suitable for, swollen film is carried out to the packaging bag of varying cross-section size.
The principle of work of tubular membrane bulging mechanism of the present invention: first swollen bagging apparatus 2 is put into tubular packaging film, then swollen bagging apparatus 2 is placed on bracket 1, first roller 23 and the second roller 11 tangent, under the magnetic interaction of first and second magnet 23,11, swollen bagging apparatus 2 is positioned in certain scope.When clamper (attached not shown in FIG.) pulls packaging film 7 to move, packaging film 7 from bracing frame 5 out, first through leading film roller 3, again through swollen bagging apparatus 2, first roller 23 and the second roller 11 rotate simultaneously, and direction is contrary, and packaging film 7 is first by distending frame 25 distending of swollen bagging apparatus 2 front end, and then strutted by the bag opening mechanism 22 of tail end, the packaging film 7 now after swollen bagging apparatus 2 is in tubular.After clamper mantle terminates, cutter cuts off packaging film 7, and because also continuing inside packaging film 7 to be strutted by bag opening mechanism 22 after cut-out packaging film 7, therefore the mouth of packaging film 7 opens all the time, clips for clamper returns the step that packaging film 7 provides key.
