Blanking and welder expect the importing of mouth when processing, quality of production higher is highly practical.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples：
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the axonometric drawing of the utility model；
Fig. 3 is the structure diagram of packaging bag preheating device in the utility model.
Embodiment
With reference to Fig. 1~Fig. 3, the utility model is a kind of opening welder with the pre- hot function of sack, including, rack 1, the machine
Frame 1 is equipped with conveying device, is equipped with successively along the conveying direction of conveying device in rack 1：
Packaging bag blanking device 2, the packaging bag blanking device 2 are used to carry out packaging bag blanking；
Expect mouth blanking and welder 5, the material mouth blanking and welder 5 are used to carry out material mouth blanking, will expect mouth one
End imports in packaging bag and is welded and fixed；
Closing device, the closing device are used for the openend of heat sealed package bag；
Packaging bag preheating device 4 is equipped between the packaging bag blanking device 2 and material mouth blanking and welder 5, it is described
Packaging bag preheating device 4 is used to heat the material mouth inlet in packaging bag, makes its temperature distortion and opens, in order to expect
Mouth blanking and welder 5 expect the importing of mouth when processing.
In the present embodiment, closing device includes the first heat-sealing device 6, the second heat-sealing device 7 and cold seal device 8, the first heat
Seal apparatus 6 is used to carry out secondary heat-sealing to the junction of material mouth and packaging bag, strengthens connection, and the second heat-sealing device 7 is used to seal
The openend of packaging bag, cold seal device 8 are used to shape by cold water.And the front of packaging bag preheating device 4 is equipped with corner cut
Device 3, for cutting out the bevel edge for importing and installing material mouth in the one of packaging bag jiao.
As shown in the figure, the packaging bag preheating device 4 includes being symmetrically set in two heating of the upper and lower of packaging bag openend
Plate, two heating plates are connected with heating unit, for heating the openend of packaging bag, are allowed to deform and open.
And certain interval is equipped between the heating plate and packaging bag, in order to packaging bag temperature distortion.So it can also prevent directly
By the openend frit seal of packaging bag.And for the packaging bag suitable for unlike material, different size scales, add described in two
Hot plate can in opposite directions or Divergence movement, to adjust the distance between two heating plates.Specifically, two heating plates include upper 33 He of heating plate
Lower heating plate 34, upper heating plate 33 are installed on a lower end length and are longer than the top board 31 of itself, and lower heating plate 34 is installed on one
Hold length to control by cylinder higher than the lower platen 32 of itself, top board 31 and lower platen 32 to move up and down, its opposite end face
It can be bonded to each other.The material mouth inlet of packaging bag is between upper heating plate 33 and lower heating plate 34 by both can be set as wrapping
When pack passes through, top board 31 and 32 relative motion of lower platen make heating plate 33 and lower heating plates 34 reaches and bag to being bonded
The setpoint distance of pack, is heated, this is one of setting means.The two of setting means are to pass through top board 31 and lower platen 32
The distance between heating plate 33 and lower heating plate 34 and packaging bag in control, before processing, set top board 31 and lower platen 32
The distance between reprocessing, and it is used as safe distance beyond the parts of two heating plates, prevents two heating plates from non-control occurs and contacts
And make packaging bag whole frit seal.
In order to preferably realize the effect of heat distortion, the heating region in the present embodiment in two heating plates is horizontal wrong
Open up and put.Its specific sets can set for the horizontal displacement of rectangular block or shift to install vertically.
A kind of opening welder with the pre- hot function of sack of the present embodiment, in packaging bag blanking device 2 and material mouth blanking and weldering
Packaging bag preheating device 4 is set between connection device 5, for being heated to the material mouth inlet in packaging bag, makes it heated
Deform and open, easy to expect the importing of mouth when expecting that mouth blanking and welder 5 are processed, quality of production higher is highly practical.
