Description

Drench film machine preheat roll device

[technical field]

The utility model relates to a kind of pouring film machine preheat roll device, is specifically related to a kind of pouring film machine preheat roll device with liquid heat, belongs to mechanical equipment technical field.

[background technology]

With the mode of warm-up mill by roll extrusion converted products being heated, is the means of generally taking in rubber, plastics, printing, chemical fibre industry at present.Especially for the product by heating of thin slice class, the mode of more suitable preheat roll heating.

The mode of heating of the preheat roll that uses has several modes such as Steam Heating and electrical heating at present, wherein, Steam Heating is by boiler steam to be sent in the preheat roll, preheat roll is heated, this mode of heating takes place easily that gas leaks and problem such as corrosion, is fewer and fewerily adopted by people.And electrical heating is that electrothermal tube directly is arranged in the preheat roll, heats preheat roll by the heating of electrothermal tube.Because electrical heating has totally, advantage such as noise is little is subjected to increasing employing, becomes the mode that the heating of preheat roll is mainly adopted.

description

1 and 2, it has disclosed a kind of pouring film machine preheat roll device, and this device is made up of first preheat roll 1 ', second preheat roll 2 ', the 3rd preheat roll 3 ', electrothermal tube 4 ', hygrosensor 5 ' and help roll 6 ', 7 '.Wherein, described electrothermal tube 4 ' is positioned at first preheat roll 1 ', can heat first preheat roll 1 ' when electrothermal tube 4 ' energising.

When this drenches the operation of film machine preheat roll device, can at room temperature be heated to 42 ℃ to the composite sheet 8 ' of high-speed motion through first preheat roll 1 ', second preheat roll 2 ', the 3rd preheat roll 3 '.Described hygrosensor 5 ' can be surveyed the variations in temperature of first preheat roll 1 '.When the temperature on first preheat roll, 1 ' surface is lower than 42 ℃, hygrosensor 5 ' will transmit signal and give electrothermal tube 4 ' and heat first preheat roll 1 ', guarantee first preheat roll, 1 ' constant temperature.Yet when electrothermal tube 4 ' began heating or stops to heat, the variations in temperature at its two ends was fast, and middle variations in temperature is slow, thereby the two ends temperature and the medium temperature of first preheat roll 1 ' be there are differences, and then caused the preheating of composite sheet 8 ' inhomogeneous.

Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of project organization more reasonably to drench film machine preheat roll device to overcome described defective of the prior art.

[utility model content]

For addressing the above problem, the purpose of this utility model is to provide a kind of simple in structure, heating-up temperature to drench film machine preheat roll device uniformly.

For achieving the above object, the technical scheme that the utility model is taked is a kind of pouring film machine preheat roll device, it comprises: first preheat roll, second preheat roll, the 3rd preheat roll and hygrosensor, described pouring film machine preheat roll device further has a heater, this heater comprises heating fluid, electrothermal tube, casing, heat-resisting pump and pipeline, wherein, described electrothermal tube is positioned at casing, and can heat the heating fluid of casing, described heating fluid is by the pipeline and first preheat roll, second preheat roll and the 3rd preheat roll are connected and can heat first preheat roll, the surface of second preheat roll and the 3rd preheat roll.

Pouring film machine preheat roll device of the present utility model further is set to: described heating fluid is a conduction oil.

Pouring film machine preheat roll device of the present utility model further is set to: it further comprises a pair of help roll.

Pouring film machine preheat roll device of the present utility model also can be set to: described hygrosensor and electrothermal tube electrically connect, and hygrosensor can transmit signal to electrothermal tube.

Compared with prior art, the utlity model has following beneficial effect: pouring film machine preheat roll device of the present utility model heats heating fluid by electrothermal tube, and then make heating fluid flow through preheat roll, can effectively avoid the uneven phenomenon of preheat roll surface temperature, problems such as thereby the preheat roll variations in temperature that has solved prior art is big, two ends temperature ratio centre is high and inhomogeneous have broad application prospects.
