Problems solved by technology

If the temperature of the heating element of the pulse heat sealer is lower than the ideal temperature, it is easy to cause the problem of film sealing; if the temperature of the heating element of the pulse heat sealer is higher than the ideal temperature, it is easy to cause the problem of sealing the film
The bottom temperature of the heating element (that is, the initial temperature of heating) changes greatly when the traditional pulse heat sealing machine is started up or after a long standby time. When heat sealing again, the bottom temperature of the heating element is different, but each time The sealing time is pre-set, so it is difficult to control the ideal temperature during heat sealing, and it is easy to cause the film to be weakly sealed or broken
And at the beginning of heating, because the bottom temperature of the heating element is low, it is not enough to reach the temperature of the sealing film, so it is easy to cause the sealing to be weak

Embodiment 2

[0042] This example is used to illustrate the performance of the impulse heat sealer of the present invention.

[0043] The pulse heat sealer heat-seals the two-layer polypropylene film material, and the pulse heat sealer heats with a heating duty ratio of 1:0.75 when it is turned on. After about 3 minutes, the temperature of the heating element 3 reaches about 160 degrees; the pulse heat sealer switches to the standby state and heats with a heating duty ratio of 1:2.5. The temperature of the heating element 3 is maintained at about 170 degrees; when the pulse heat sealer is heat sealing the polypropylene film, it switches to the heat sealing heating state, and heats with a heating duty ratio of 1:1.5, and the temperature of the heating element 3 is maintained at At about 170 degrees, the heat-sealed parts of the two-layer polypropylene film material are all heat-sealed. Until the heat sealing is completed, the induction element is disconnected and then turned to the standby ...

Abstract

The present invention provides a pulse heat sealing machine heating device and a pulse heat sealing machine with the heating device. The heating device of the pulse heat sealing machine comprises a heating control device (1), a switching device (2), a heating element (3), a heat sealing sensor device (4) and a power supply device (5). When the heating control device (1) receives the signal which is from the heat sealing sensor device (4) and expresses that the pulse heat sealing machine is in the state of heat sealing, the ratio of heating time and cooling time of the heating element (3) is X1, otherwise, the ratio of heating time and cooling time of the heating element (3) is X2 and X1 is more than X2. The pulse heat sealing machine which uses the heating device of the present invention has invariable base heat, stable sealing effect and high production yield.

Description

technical field [0001] The invention relates to a heating device of a pulse heat sealing machine and a pulse heat sealing machine with the heating device. Background technique [0002] The pulse heat sealer is suitable for heat sealing of plastic film and products added in the middle of the film. [0003] Such as figure 1 As shown, the heating device of the existing pulse heat sealer includes a heating control device, a switch device, a heating element, an induction device and a power supply device.
