Description

The temperature-control circuit that is used for gluing machine

Technical field

The utility model relates to the control or the regulating system of non electrical quantity, relates in particular to sensing element and has the temperature control that varies with temperature resistance, particularly relates to the heating and temperature control of gluing machine rubber roll assembly and overtimely adds thermal protection.

Background technology

The temperature regulation mechanism of prior art gluing machine is that the power switch that adopts a double-pole to throw is finished temperature adjustment work more, and such circuit can only have two thermoregulation ranges, one when being low temperature 108 ℃ ± 5 ℃, and one when being high temperature 125 ℃ ± 5 ℃.It is the glued membrane of 75 μ m～150 μ m that these two temperature ranges can only be selected thickness, and thickness just can't have been crossed glue less than glued membrane or the cold glued membrane of mounting of needs of 75 μ m.And the gluing machine of prior art does not all have timing function, can not get back to holding state automatically when not using gluing machine, not only wastes electric energy, but accident such as fire hazard also.

Summary of the invention

The technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of can effectively enlarge the thickness range of glue glued membrane and can do cold paperhanging machine, also have clocking capability, not only saves energy also can be avoided the temperature-control circuit that is used for gluing machine that overheat accident takes place.

The utility model solves the problems of the technologies described above the technical scheme that is adopted, manufacture and design a kind of temperature-control circuit that is used for gluing machine, be included as the power switching device that heats rubber roll and connect and regulate the heater primary power, especially also comprise temperature-sensing element, comparing element and timing mechanism; The feedback output end f of described temperature-sensing element is electrically connected one of first input end of comparing element, two of the first input end of this comparing element connects the first reference voltage Uref1, and first output terminal of described comparing element then is electrically connected the control end of described power switching device behind resistance; Described timing mechanism comprises timing circuit DT1 and the relay K of being controlled by this circuit DT1 1, and described relay K 1 is switched on or switched off the control power Vcc of comparing element and sensing element.

Compare with prior art, the technique effect that the utility model is used for the temperature-control circuit of gluing machine is: simple in structure, with low cost, but can effectively enlarge glue film thickness range of choice, and can do cold paperhanging machine, also have clocking capability, not only saves energy also can avoid overheat accident to take place.
