Chartered plane membrane knife rest film feeding air curtain device in bar shaped
Technical field
The utility model provides chartered plane membrane knife rest film feeding air curtain device in a kind of bar shaped, relates to packing machinery technology.
Background technology
The radical function of membrane knife rest is the process that the volume film in Tuo Mo mechanism is carried accurately and cut off by the length of setting.For stick pack, when film feeding, to overcome the unfavorable factor that film self and lower film working environment bring: as wider in film (300-450 left and right), film very thin (0.035-0.05 left and right) film feeding long (260-330 left and right); Simultaneously the smoothness of film and and film on the unfavorable factor such as electrostatic adherence; The region that film is carried is dynamic irregular fixed air-flow environment, be subject to traditional film feeding guiding device because of (as copper pipe mode is installed) processing and the very difficult control of installation error, thereby being directed at lower film and being also subject to except being subject to packaging film self unfavorable factor cutting membrane knife holder 11 rotations produces air inversions or other friction or static damping and affects, thereby there is producing the smooth more waste product that produces of lower film: as Bales Off, film up and down or the defective products such as left and right drift.
Utility model content
The technical problems to be solved in the utility model is the defect that overcomes prior art, thereby chartered plane membrane knife rest film feeding air curtain device in the bar shaped that a kind of steady quality, production efficiency are high is provided.
For achieving the above object, this practicality provides chartered plane membrane knife rest film feeding air curtain device in a kind of bar shaped, the utility model adopts following technical scheme: chartered plane membrane knife rest film feeding air curtain device in bar shaped, is characterized in that being made up of the film feeding gas curtain assembly, membrane assembly and the cutter assembly that are arranged on knife rest side plate (1); Described film feeding gas curtain is installed on membrane assembly below, forms by leading gas curtain on film (2) and leading gas curtain under film (3); The described gas curtain on film (2) of leading is led lamina membranacea (2-6) by upper gas curtain right supported plate (2-1), two L-type connecting panels (2-2), upper gas curtain horizontal support plate (2-3), upper gas curtain admission port (2-4), upper gas curtain left supported plate (2-5) and upper gas curtain and is formed; The described gas curtain under film (3) of leading is made up of charging pressing plate (3-1), charging pressing plate left supported plate (3-2), lower gas curtain support plate (3-3), charging pressing plate right supported plate (3-4), lower gas curtain admission port (3-5) and lower gas curtain guide plate (3-6); Described membrane assembly is the pressing of being controlled membrane drive roll (4) and membrane driven voller (5) by stitching wheel folding handle (10), then drives operation with membrane motor (6); Described lead gas curtain on film (2) and lead between gas curtain under film (3) cutter assembly is installed; Described cutter assembly is made up of moving cutting knife (7), quiet cutting knife (8), moving cutting knife driving chain wheel (9) and moving knife holder (11), and moving knife drives running with motor.
On the basis of the above, described in, lead gas curtain under film (3) and be positioned at the tangent line below of the moving knife holder (11) that moving cutting knife (7) installs; Workpiece packing passage in described gas curtain under film (3) below of leading.
Advantage of the present utility model: 1, the utility model has solved because of the not smooth more waste product problem that produces of lower film.Production efficiency increases substantially, and product design is stablized, and the processing of applicable conversion plurality of specifications part, highly versatile.
2, the utility model can realize parallel for film, have simple and compact for structure, steady for film, the advantage of dependable performance.

The specific embodiment
With best embodiment, the utility model is described in detail below.
As shown in Fig. 1 and Fig. 6, chartered plane membrane knife rest film feeding air curtain device in bar shaped, is characterized in that being made up of the film feeding gas curtain assembly, membrane assembly and the cutter assembly that are arranged on knife rest side plate (1); Described film feeding gas curtain is installed on membrane assembly below, forms by leading gas curtain on film (2) and leading gas curtain under film (3); The described gas curtain on film (2) of leading is led lamina membranacea (2-6) by upper gas curtain right supported plate (2-1), two L-type connecting panels (2-2), upper gas curtain horizontal support plate (2-3), upper gas curtain admission port (2-4), upper gas curtain left supported plate (2-5) and upper gas curtain and is formed; The described gas curtain under film (3) of leading is made up of charging pressing plate (3-1), charging pressing plate left supported plate (3-2), lower gas curtain support plate (3-3), charging pressing plate right supported plate (3-4), lower gas curtain admission port (3-5) and lower gas curtain guide plate (3-6); Described membrane assembly is the pressing of being controlled membrane drive roll (4) and membrane driven voller (5) by stitching wheel folding handle (10), then drives operation with membrane motor (6); Described lead gas curtain on film (2) and lead between gas curtain under film (3) cutter assembly is installed; Described cutter assembly is made up of moving cutting knife (7), quiet cutting knife (8), moving cutting knife driving chain wheel (9) and moving knife holder (11), drives running with motor.
On the basis of the above, described in, lead gas curtain under film (3) and be positioned at the tangent line below of the moving knife holder (11) that moving cutting knife (7) installs; Workpiece packaging film in described gas curtain under film (3) below of leading.
The utility model principle of work: described in lead gas curtain on film (2) and be positioned at the below of membrane drive roll (4) and the driven press bonding roller of membrane (5), in the time that packaging film is down carried with the traction of press bonding roller (5) by drive roll (4), owing to leading the local cavity of meeting formation between gas curtain on film (2) and packaging film, when upper gas curtain admission port is constantly filled with after stable air-flow, eddy spray gas port produce the same many exhaust streams of gas curtain with in the partial cavity forming by becomes the 90 air guide port b that spend to lead away with air nozzle a, thereby make packaging film and upper gas curtain lead lamina membranacea (3-6) thus between produce relative negative pressure and make attitude that packaging film can keep straight line along leading film under the surface smoothness of lamina membranacea, thereby packaging film is sent under moving cutting knife (7) and quiet cutting knife (8).
Lead gas curtain under film (3) and be positioned at the tangent line below of the moving knife holder (11) that moving cutting knife (7) installs, its function mainly makes logical stable the sending in the packing groove of frame of the packaging film of the cutting knife having led to.Lower gas curtain eddy spray gas port a one-tenth same with eddy current air guide port b structure 90 degree angles, lower gas curtain admission port (3-5) with upper gas curtain admission port (2-4) thus input high pressure gas simultaneously and stablize packaging film is sent into predetermined multiple package position thereby packaging film is accurate when the pattern " supports " that packaging film forms relay baton during through lower gas curtain (3).
Finally it should be noted that: obviously, above-described embodiment is only for the utility model example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all embodiments.And the apparent variation of being amplified out thus or variation are still among protection domain of the present utility model.
