Description
Technical field
The present invention relates to a kind of mouth-sealing method sealing two layers of edge curling seal of aluminium foil cutlery box, belong to aluminium foil cutlery box with
The technical field of automatic rolling sealing of aluminium foil cutlery box lid.
Background technology
Existing aluminium foil cutlery box sealing mode typically has three kinds:
The first is to coat heat-seal adhesive at cutlery box aluminum foil cover, is reached the purpose of sealing by machinery heating, this
The defect of sealing mode is heat-seal adhesive under aluminium foil cutlery box contains food or heating state, easily makes heat-seal adhesive melt,
Cause not reaching sealing effectiveness and even cause food spoilage；
The second sealing is aluminium foil cutlery box lid in bulk, individual sealing manual, easily causes when Manual Packaging food
Thing secondary pollution, it is often more important that do not reach sealing effectiveness.
The third sealing is to use mould press seal, utilizes aluminum sealing lid crimping, it is achieved the sealing of aluminium foil cutlery box,
But the mode of existing mould press seal, the poor flatness of aluminum foil cover, difficulty of labelling on aluminum foil cover, seal
Poor effect, causes the food shelf-life shorter.
Summary of the invention
The technical issues that need to address of the present invention are: the sealing mode of existing sealing aluminium foil cutlery box, do not reach
Sealing effectiveness causes food spoilage or shortened shelf life, and food easily causes secondary pollution, covers flatness
Low, aesthetic measure is low, and is difficult to label thereon.
The present invention takes techniques below scheme:
A kind of compacting tool set sealing two layers of edge curling seal of aluminium foil cutlery box, including: part of the upper die, described upper mold
Part include decking 1, cope match-plate pattern 3, upper piston 2, upper clip seat 4, upper clip 6, upper cavity die 7, on
Die installing plate 5；Part of the lower die, described part of the lower die includes at the bottom of lower blank holder 8, lower cavity die 9, lower cavity die

Targeting part includes guide pillar guide pin bushing；Upper cavity die 7 profile guides with upper clip 6 inner hole, and upper cavity die is installed
Plate 5 connects upper cavity die 7 from top to bottom, and upper piston 2 acts on upper cavity die installing plate 5, and upper clip seat 4 is certainly
Upper and clip 6 in lower connection, cope match-plate pattern 3 connects clip seat 4 from top to bottom, and the forcing press of outside is from upper
Lower connection cope match-plate pattern 3, drives whole part of the upper die, moves up and down；Outside lower blank holder 8 endoporus is with lower cavity die 9
Shape coordinates guiding, and lower blank holder 8 is provided with crimping groove, under lower cylinder 14 is promoted by lower cylinder push rod 11
Blank holder 8 back springing type moves, and lower cavity die 9 is fixed on lower cavity die base 10, and lower cavity die base 10 is fixed
On lower bolster 12.
Further, described part of the lower die also includes lower piston 13, described lower piston 13 and lower cylinder push rod
11 connect.
The mouth-sealing method of a kind of above-mentioned compacting tool set, comprises the following steps: forcing press drives part of the upper die whole
Body down moves, and on upper cavity die 7 lower plane and lower cavity die 9 during plane contact, upper cavity die stops fortune downwards
Dynamic, the stroke of a press drives part of the upper die to make clip 6, upper clip seat 4 continue to move down, lower blank holder
On 8, aluminium foil is compressed under lower cylinder 14 acts on by plane with upper clip 6 lower plane, continues to move downward generation
Stretching；Meanwhile, the aluminium foil of plane on lower cavity die 9, under upper piston 2 acts on, is compressed by upper cavity die 7, on
Clip 6 endoporus makes the aluminium foil being stretched pull down along the profile of lower cavity die 9 with lower cavity die 9 gap
Stretching motion, when forcing press continues to be moved downwardly to minimum point, upstanding edge has stretched；The stroke of a press is gone to
After minimum point, upper cavity die stroke is covered, and drives part of the upper die up to move, and moves at upper cavity die 7 in part of the upper die
Before lower plane is separated from plane on lower cavity die 9, upper piston 2 is relatively gone up clip 6 and is moved downward, lower cylinder
The lower blank holder 8 upwards resilience of push rod 11 effect, the aluminium foil of the upstanding edge being stretched is at upper clip 6 and lower cavity die
In 9 spaces, on lower blank holder 8 during resilience, the aluminium foil edge that the crimping groove effect of lower blank holder is stretched
Crimping groove to Rolldown hem molding, when lower cylinder 14 stroke is to peak, on lower blank holder 8, plane is with recessed
Planar horizontal on mould 9, two layers of edge curling seal complete；Forcing press continues up, and upper and lower mould disengages.
The feature of the technical program is: utilizes the relative motion of part of the upper die and part of the lower die, is continuously finished
Two layers of crimping procedures of aluminium foil cutlery box, it is achieved that pressurizing window, seal degree can hold liquid and not leak,
, being realized to Rolldown hem by the crimping groove on lower blank holder, aluminium foil is opened by outside when Rolldown hem meanwhile
Power, can make aluminum sealing lid extend smooth, and upper surface can be made without protrusion to Rolldown hem, it is simple to heat
The label of envelope food.
The beneficial effects of the present invention is:
1, good sealing effect, effective period of food quality is long.
2, aluminium foil expends few, low cost.
3, upper surface is smooth, it is simple to heat-sealing food label.
4, Sealed dining box profile is smooth, attractive in appearance.
