Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Fig. 1 is integral structure schematic top plan view of the present utility model.

Fig. 2 is the A-A cross-sectional schematic of Fig. 1.

Fig. 3 is the schematic diagram of optional crank motion structure of the present utility model.

In figure: heating sealing device 1, housing 11, thermal insulation layer 12, heater element 13, weld tabs 14, heat storage blocks 15, frame 16, spring 17, cam 18, push rod 19, thermal transmitter 101, eccentric wheel 102, connecting rod 103, slide rail 104, feedway 2, contact roller 3, packaging bag 4.

The specific embodiment

In Fig. 1 ~ 2, a kind of closing device, comprises the feedway 2 for delivery of packaging bag 4, for compressing the contact roller 3 of sack, the contact roller in this example adopts the structure of positioned opposite, but adopts a side, for example upside is arranged contact roller, and opposite side arranges that the structure of guide rail or deflector roll is also feasible.Position near contact roller 3, is furnished with reciprocating heating sealing device 1 in opposite directions.Structure, in course of conveying, is compressed the sack of packaging bag 4 by contact roller 3 thus, and by reciprocating heating sealing device 1, sack is tamping, thereby realize, continuously packaging bag 4 is sealed.In the process compressing in opposite directions at heating sealing device 1, can cause the instantaneous stopping of packaging bag 4, it is useful therefore adopting step feedway 2, and this is common in the prior art, for example adopt sheave, half gear drive to drive, or adopt stepping motor to drive.

Preferred as in Fig. 2, in described heating sealing device 1, be provided with thermal insulation layer 12 in housing 11, thermal insulation layer 12 adopts the materials such as asbestos, the heater element 13 being arranged in thermal insulation layer 12 is connected with weld tabs 14, weld tabs 14 crank motion process discontinuous contact with the sack of packaging bag 4.The heat loss that thermal insulation layer 12 can reduce heater element 13 is set, thereby reduces the operating temperature of heater element 13, or work-hours, to extend the service life of heater element 13.Conventionally the operating temperature of heater element 13 is at 110 ℃.Heater element 13 adopts resistor wire conventionally, and it is also feasible adopting graphite rod.
