Abstract
The utility model relates to the technical field of film-blowing die heads, in particular to a film-blowing die head of a bone clamp type sealing bag, which comprises a die head body, a die and a die core, wherein the die is arranged in an inner cavity of the die head body, the die core is arranged on the die, a clearance is remained between the outer edge of the die core and the inner cavity of the die head body, two groups of female grooves and two groups of male grooves, which are used for forming the shape of a bone belt, are arranged on the die core and are respectively arranged at a position close to the position of the outer edge of the die core, and two groups of concave bone belts and two groups of convex bone belts, which are adjacent, can be arranged on a long cylindrical bag body extruded on the die core. After the long cylindrical bag body is cut in an equidistant way and sealed hotly into two halves, the two halves are cut between each group of concave bone belts and each group of convex bone belts in a way of penetrating through the center of a circle and are divided into two small bags. In this way, the production efficiency is greatly enhanced, the yield is enhanced by one time, and bags with different specifications can be simultaneously produced.
Description
Technical field:
The utility model relates to blown film die head technical field, refers in particular to a kind of bone folder formula sealing bag blown film die head.
Background technology:
At present, the bone folder formula sealing bag that occurs on the market is the elongate recessed bone band that has groove in sealing part one side, and opposite side should be the elongated protruding bone band that has salient angle relatively, and the two cooperates the sealing bag involution.In the prior art, make this bone folder formula sealing bag and mostly adopt single air pressure blown film, blown film die head form is: the outer ring is the annular die body, inner chamber at the die head body is provided with column core rod and mould, leave uniform gap between core rod and the die head body, at adjacent a pair of cloudy groove and the positive groove of having in the place, outer of core rod, bone folder formula sealing bag is extruded from the space of die head, cutting heat-sealing then forms a bone folder formula sealing bag.But the deficiency that existing blown film die head exists is: production efficiency is low, and each cutting heat-sealing only produces a sealing bag, can not satisfy the growing demand of people.In addition, the cloudy groove of existing blown film die head and positive groove are out the place, outer at core rod, cloudy groove, positive groove directly with core rod, die head body between the gap be communicated with, because thickness is bigger, bag easy deformation and generation wrinkle are not attractive in appearance during cooling in the place that the bone band is arranged for the sealing bag of extruding, the shape instability, speed of production is slow, and bone band and bag can only be used with a kind of raw material production, color dullness.
The utility model content:
The purpose of this utility model be exactly the deficiency that exists at prior art and provide a kind of can two sealing bags of disposable production, dimensionally stable, good looking appearance, the fast bone folder formula sealing bag blown film die head of speed of production.
To achieve these goals, the technical solution adopted in the utility model is: it includes the die head body, be arranged on mould in the die head chamber body, be located at the core rod on the mould, leave the gap between the outer of core rod and the die head chamber body, offer two groups of cloudy groove and positive grooves that are used to form the bone belt shape on the core rod, cloudy groove and positive groove are separately positioned on the position near the core rod outer.
Described cloudy groove, positive groove respectively with the core rod outer mutually across a certain distance.
Described spacing is 2～20mm.
Described spacing is preferably 7～8mm.
Position near the left and right sides on the described core rod respectively is provided with one group of adjacent cloudy groove and positive groove, and the one-tenth center, center with respect to core rod between two groups of cloudy grooves of the left and right sides and the positive groove is symmetrically distributed.
Also can be provided with two adjacent cloudy grooves in the position near a side on core rod, the position near opposite side on core rod is provided with two adjacent positive grooves.
Described mould inside offers the defeated material passage that is communicated with cloudy groove and positive groove, and the bottom of die head body is provided with two charging apertures, and one of them charging aperture is communicated with the inner chamber of die head body, another charging aperture and defeated material channel connection.
The utility model beneficial effect is: the utility model includes the die head body, be arranged on the mould in the die head chamber body, be located at the core rod on the mould, leave the gap between the outer of core rod and the die head chamber body, offer two groups of cloudy groove and positive grooves that are used to form the bone belt shape on the core rod, cloudy groove and positive groove are separately positioned on the position near the core rod outer, have two groups of adjacent recessed bone bands and protruding bone band on the long tube bag of extruding on the core rod, after long tube bag is equidistantly cut heat-sealing into two, organize from each again and pass center of circle cutting between recessed bone band and the protruding bone band, be divided into two pouches, improved production efficiency so greatly, output doubles, and can produce the bag of different size simultaneously.
In addition, cloudy groove, positive groove respectively with the core rod outer mutually across a certain distance, bone band and bag are separately extruded, and the formation sealing bag that just is bonded together after extruding certain altitude is then separately extruded in cooling procedure between bone band and the bag and can not be influenced each other, bag can not be out of shape and produce wrinkle, good looking appearance, dimensionally stable, speed of production is fast, and bone band and bag can be with two kinds of different raw material productions, and color is various.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the vertical view of another embodiment of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1,2, the utility model includes die head body 1, be arranged on mould 2 in die head body 1 inner chamber, be located at the core rod 3 on the mould 2, leave the gap between the outer of core rod 3 and die head body 1 inner chamber, offer two groups of cloudy groove 4 and positive grooves 5 that are used to form the bone belt shape on the core rod 3, wherein, respectively be provided with one group of adjacent cloudy groove 4 and positive groove 5 near the position of the left and right sides on the core rod 3, the one-tenth center, center with respect to core rod 3 between two groups of cloudy grooves 4 of the left and right sides and the positive groove 5 is symmetrically distributed.Have two groups of adjacent recessed bone bands and protruding bone band on the long tube bag of extruding on the core rod, after long tube bag is equidistantly cut heat-sealing into two, organize from each again and pass center of circle cutting between recessed bone band and the protruding bone band, be divided into two pouches, improved production efficiency so greatly, output doubles, and can produce the bag of different size simultaneously.
