Description

Notching device of bag closing machine

The utility model relates to a kind of notching device of wrapping machine envelope.

Used high-intensity compound package material in the world widely,, and cut in the limit portion of sealing of bag and to stay an osculum, torn when making things convenient for the user to break seal by the continuous packing envelope of wrapping machine.Now, this processing all is to beat a mouthful device by the fly-cutter type on the wrapping machine to finish.As: Komack three or two Network that Japanese Xiao Song Co., Ltd. produces The High-Speed Automatic powder filling wrapping machine of formula is a kind of typical case's type.This machine is that a circular beater plate is set outside the vertically sealed roller system is moving knife with the clamping cutting knife, makes cutterhead together with the moving knife rotation of being held by driving system, cooperates with dead knife and bag sealing device system on being in relative position, is implemented to beat mouth and processes.This kind beaten a mouthful device, owing to must set up a cover driving system, thereby complex structure, envelope with beat mouthful cooperates synchronously adjust inconvenient, also increased the manufacturing cost of wrapping machine,, constituted the difficulty of introducing otch processing for the type of machine accessory compact in design and divided dose forms may bag.

The purpose of this utility model is: overcome above-mentioned weak point of the prior art, provide a kind of relative cutting knife pair of cutting edge of on two vertically sealed rollers, setting up to society, implement carrying out of packing envelope thereby the vertically sealed roller of realizing accompanying rotates, shear the notching device of finishing the otch processing of envelope by being periodically clutch with the incorporate cutting knife pair of vertically sealed roller.

Task of the present invention is to finish according to following technical scheme: the notching device of this kind wrapping machine envelope, formed by parts such as roller driving system, a pair of vertically sealed roller and cutting knife pairs, its unique distinction is that said a pair of vertically sealed roller is the roll surface that keeps the arc of symmetry along cylindrical axis parallel cut-out, its roller end is with one heart two shapes of external integrated roll shaft and vertically sealed roller (1) and the vertically sealed roller (2) that size is identical, roll surface rotates pressing relatively again, fixedly is pasted with the cutting knife pair again on the roll body of the same side of roll surface.

The secondary system of the every pair of cutting knife is made of cutting knife assembly two cuboid, square and other geometrical bodies that fixedly are attached at the straight and sword appearance of two cutting edges on the vertically sealed roller etc. respectively, that the cutting edge cross section is the plane again respectively and is the inclination angle.

Two cutting knifes all are with cutting edge parallel alignment roll surface, in roll body contraposition place of two roll surface homonymies pressing close to roller end.

Two vertically sealed rollers can make respectively two groups, three groups and many groups equidistantly and etc. arc length and roll surface one to one.

The roller end cross section can be same as the geometric configuration that roll surface and roll body cross section are constituted, and also can be the circle of cylinder own.

Description of drawings of the present utility model:

Fig. 1 is a notching device major part constructional drawing

Fig. 2 is the constitution diagram of vertically sealed roller half-twist

Fig. 3 is a scheme drawing of setting up two pairs of cutting knife pairs

Fig. 4 is a scheme drawing of setting up three pairs of cutting knife pairs

The utility model will elaborate embodiment in conjunction with the accompanying drawings:

Embodiment 1:

The notching device of the wrapping machine envelope of the utility model, shown in Fig. 1,2 and 3: adopting a pair of vertically sealed roller is vertically sealed roller (1) and vertically sealed roller (2), they are respectively the roll surfaces (3) that keep the arc of its radial symmetry along the parallel cut-out of cylindrical direction of axis line, at roller end (4) external incorporate roll shaft (5) with one heart, the shape of two vertically sealed rollers and identical, the rotatable relatively pressing of roll surface (3) of size fixedly are pasted with the cutting knife pair again on the roll body (8) of the same side of roll surface (3).

The every pair of cutting knife pair all is to be made of two cutting knife (6) and cutting knifes (7) that are individually fixed in the straight and sword appearance of cutting edge on vertically sealed roller (1) and the vertically sealed roller (2) etc., they can make cuboid, square and other geometrical body, and used material can be the material that Triple steel, alloy steel and hard alloy etc. have higher hardness and abrasion test

Two cutting knifes, promptly cutting knife (6) is respectively with its cutting edge cross section of cutting knife (7) and is the plane and is the inclination angle shape, and clutch is sheared in rotation.

Cutting knife (6) and cutting knife (7) all are the contrapositions of being fixed in the homonymy roll body of roller end (4) with cutting edge parallel alignment roll surface (3), its fixed form can be welding, bonding, preferably then be to screw in fixed orifice (11) on the roll body (8) and fastening cutting knife in its vertical displacement aperture (9) of offering two parallel strips of cutting knife (6) and cutting knife (7) upper edge with fix screw (10) respectively with roll body (8) attaching face, so that the secondary easy disassembly sharpening of cutting knife and adjust and shear.

The notching device of the utility model is in implementing otch processing, when strip of wrapping material is imported counterrotating vertically sealed roller (1) and vertically sealed roller (2) through indulging envelope, a pair of vertically sealed roller is with its cooresponding roll surface (3) rotation pressing horizontal sealing, then with the involutory shearing of the secondary cutting edge of the incorporate cutting knife of vertically sealed roller, thereby finish under the horizontal sealing limit of envelope, cut the processing of staying an osculum on the vertical edge sealing.Along with envelope carries out continuously, a pair of vertically sealed roller rotation of accompanying, the cutting knife pair is periodically clutch and realizes that each envelope cuts the processing of staying an osculum.

Embodiment 2:

State with reference to accompanying drawing 3 and 4.Look the packaging bag size, vertically sealed roller (1) and vertically sealed roller (2) can be made have two groups, three groups or many groups equidistantly with etc. arc length cooresponding roll surface (3) and set corresponding cutting knife pair, thereby a pair of vertically sealed roller is whenever rotated a circle can corresponding envelope cut two, three or a plurality of envelope.

Roller end (4) can be made the cross section according to condition of service and be same as roll surface (3) and roll body (8) geometric configuration that the cross section constituted, the circle of trilobal cross as shown in Figure 4 and cylinder shown in Figure 3 itself.

The notching device of the packing machine envelope of the utility model is compared with prior art, has remarkable advantage:

Set up the cutting knife that a pair of cutting edge is split on two vertically sealed rollers, consist of and the integrated cutting knife pair of vertically sealed roller, thereby be implemented in vertically sealed roller and rotate enforcement packing envelope simultaneously, be periodically clutch by the cutting knife pair with roller and shear the otch processing of finishing envelope, thereby save the transmission system of beating mouthful device, reduce to take up space, simplify the structure, reduced the complete machine manufacturing cost, simultaneously because envelope cooperates synchronously with otch, easy to adjust, easy operating and maintenance have also guaranteed crudy. This kind notching device, the type that is particularly suitable for machine accessory compact in design and divided dose forms may bag is introduced, and has popularizing value.
