The specific embodiment
Now 1 to 11 couple of the utility model embodiment is described further in conjunction with the accompanying drawings.
Fig. 1 and Fig. 3 show two embodiment of the heat-sealing limit device of microwave food packaging bag, comprise support 7, lower bolster 6, cope match-plate pattern 3, electro-heat equipment 2, pilot bar 1, retracing spring 5, actuating device 8; Cope match-plate pattern 3 is close to electro-heat equipment 2 and is connected firmly together; Cope match-plate pattern 3 baseplanes are provided with the recess 31 that laterally runs through this plane; Be provided with the concordant pressure pad 4 in baseplane with it in the recess 31; Lower bolster 6 and actuating device 8 are installed on the support 7; The upper end of two pilot bars 1 connects firmly the both ends on electro-heat equipment 2 respectively, and the middle part is with retracing spring 5, and bottom kink respectively is inserted through lower bolster 6 both ends through holes, and lower end and actuating device 8 power connect; Under the power driven of actuating device 8, cope match-plate pattern 3 moves up and down, thereby make the state that the plane is contact or separates on cope match-plate pattern 3 baseplanes and the lower bolster 6, to realize the hot-forming of heat-sealing plastic sheeting heat-sealing frame 91 shown in Fig. 9, Figure 10 or Figure 11 and gas safe release mouth 92.
Fig. 2, Fig. 4, Fig. 5 and Fig. 6 illustrate the recess 31 that laterally runs through cope match-plate pattern 3 baseplanes that rectangle, trapezoidal and arcuate shape are set respectively, and the shape suitable pressure pad 4 that matches is set respectively in the recess 31 with it.The coefficient of thermal conductivity of the material of pressure pad 4 is lower than the material coefficient of thermal conductivity of cope match-plate pattern 3 bodies, with the temperature on cope match-plate pattern 3 bodies at the bottom of the temperature value of guaranteeing pressure pad 4 places, make the anchoring strength of its molten plastic film far below the anchoring strength of cope match-plate pattern 3 body place molten plastic films.
Fig. 7 illustrates the pressure pad of being made by the polytetrafluoroethylene cloth 4, and this is the corresponding high temperature of a kind of ability, again suitable coefficient of thermal conductivity and elastomeric material is arranged, and its hardness is far below the hardness of cope match-plate pattern 3 bodies made from steel.
Fig. 8 illustrates pressure pad 4 and is single layer polytetrafluoroethylene cloth, comprises basic unit 41, adhesive-layer 42, is keeping good adhibit quality in the serviceability temperature scope.
The pressure pad 4 that recess 31 places that Fig. 2, Fig. 4, Fig. 5 and Fig. 6 illustrate respectively are provided with has one deck at least, to guarantee that pressure pad 4 places act on the positive pressure of heat-sealing on the plastic sheeting and are lower than cope match-plate pattern 3 body places and act on positive pressure on the heat-sealing plastic sheeting, to form gas safety liberation port 92; When the lower gas safety liberation port place intensity of needs, increase the number of plies of pressure pad 4; Otherwise, during higher if desired gas safety liberation port place intensity, reduce the number of plies of pressure pad 4.Set recess 31 has one at least on cope match-plate pattern 3 baseplanes, to guarantee forming at least one gas safety liberation port 92 when sealing compression moulding.The pressure pad 4 at recess 31 places acts on the pressure intensity at food pack heat-sealing gas safety liberation port 92 places less than 5N/15mm, to guarantee that when heating, the water vapours that produced in the food pack 9 can come out in safe releases.When the size of food pack 9 was big, gas was more in the bag, can suitably increase the quantity of gas safety liberation port 92 at the edge sealing place.
The operating process of as shown in figures 1 and 3 packaging bag heat-sealing limit device is such: after heat-sealing limit 91 alignment with the food pack 9 of Fig. 9, Figure 10 or Figure 11, be put between the cope match-plate pattern 3 and lower bolster 6 that installs pressure pad 4, the cope match-plate pattern 3 that will heat is then depressed and is stopped and moments later rises cope match-plate pattern 3.Cope match-plate pattern 3 and pressure pad 4 had both formed heat-sealing limit 91 and gas safe release mouth 92 simultaneously at the hot pressing trace place of food pack 9 like this.Take out the food pack 9 that has sealed at last.
Use as the packaging bag heat-sealing limit device of Fig. 1 or Fig. 3 can or install in the process that encapsulates after the food at manufacturing food pack 9, disposablely will seal limit 91 and gas safe release mouth 92 processes simultaneously.Thereby simplified operation, reduced cost, improved production efficiency.
Food pack heat-sealing of the present utility model limit device is not only applicable to the heat-sealing limit of microwave food packaging bag and uses, be applicable to that also other material is that use on the heat-sealing limit of the packaging bag of plastic sheeting class, as be applicable to the heat-sealing limit use etc. of steamer based food packaging bag.
