Abstract
The utility model discloses an automatic temperature detection device for a UV (ultraviolet) lamp of a curved surface offset press. The automatic temperature detection device comprises a lamp box, wherein a suction opening is formed at the top of the lamp box; a reflection cover is arranged in the lamp box; and a UV lamp tube is mounted in the reflection cover. The automatic temperature detection device is characterized in that a thermocouple is arranged on a side wall of the lamp box; a hot electrode of the thermocouple is positioned in the reflection cover; and the thermocouple is connected with a data feedback signal line. According to the automatic temperature detection device, the thermocouple is adopted for detecting the temperature variation of a UV lamp section; the precise rate is high; the response velocity is high; and printed finished products are natural, bright in color and good in effect.
Description
Technical field
The utility model relates to a kind of offset press auxiliary equipment, is specifically related to a kind of curve offset press UV light temperature automatic detection device.
Background technology
Printing ink commonly used in offset press has common ink and UV(UltraViolet, ultraviolet ray) printing ink.Common ink utilizes printing ink nature boiling characteristics to come dry.UV printing ink can't be realized the nature volatile dry, often realizes the drying of UV printing ink in printing machine with air-cooled UV lamp box.Be provided with the UV fluorescent tube in the UV lamp box, the UV fluorescent tube is lighted by the special-purpose special high voltage source that the outside provides.Because fluorescent tube not only penetrates ultraviolet ray, also produce the infrared high-temperature radiation, printed matter below the fluorescent tube or other article are produced high temperature, the adverse effect such as light.
There is the blower fan exhausting at tradition UV lamp box place, reaches the heat radiation purpose, sends out fluorescent tube service time thereby effectively prolong.But because printed document has the difference of material and thickness, the power of UV lamp needs to change thereupon, and the temperature at lamp box place will be along with change simultaneously.Most printed documents need the constant curing warm area of 180 ~ 200 degree, and obviously traditional method can't satisfy the effect that the print surface pattern is natural, gloss is distinct.
Summary of the invention
The purpose of this utility model is to overcome problems of the prior art, provides a kind of and can automatically control UV lamp district temperature, guarantees the curve offset press UV light temperature automatic detection device of printing quality.
Technical solution of the present utility model is: a kind of curve offset press UV light temperature automatic detection device, comprise lamp box, the top of described lamp box is provided with suction opeing, be provided with reflection shield in the lamp box, the UV fluorescent tube is installed in the described reflection shield, it is characterized in that: be provided with thermocouple on the sidewall of described lamp box, the thermode of described thermocouple is positioned at reflection shield, is connected with the data feedback holding wire on the described thermocouple.
The installation site of described thermocouple is positioned at the middle part of lamp box, and thermocouple is 1/3～1/4 of lamp box height apart from the distance at lamp box top.
The utility model is used the temperature that thermocouple comes perception UV lamp district, and the action by PLC system control suction opeing, because the sensitivity of thermocouple is high, slight change that can sense temperature, the reaction speed of PLC system is also very fast, such combination can realize the automatic control of UV lamp district temperature, makes it to keep invariable, makes printed matter reach the effect of nature, gloss distinctness.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: lamp box 1, suction opeing 2, reflection shield 3, UV fluorescent tube 4, thermocouple 5, data feedback holding wire 6.
The specific embodiment
Referring to Fig. 1, a kind of curve offset press UV light temperature automatic detection device, comprise lamp box 1, the top of described lamp box 1 is provided with suction opeing 2, be provided with reflection shield 3 in the lamp box 1, in the described reflection shield 3 UV fluorescent tube 4 is installed, be provided with thermocouple 5 on the sidewall of described lamp box 1, the installation site of described thermocouple 5 is positioned at the middle part of lamp box 1, thermocouple 5 is 1/3～1/4 of lamp box 1 height apart from the distance at lamp box 1 top, and the thermode of described thermocouple 5 is positioned at reflection shield 3, is connected with data feedback holding wire 6 on the described thermocouple 5, data feedback holding wire 6 is connected with backstage PLC system, for the PLC system provides Data support.
The course of work of the present utility model is: the operator sets required temperature value in backstage PLC system first, when whole UV lamp box work, thermocouple 5 can gather the temperature in the reflection shield 3, and send this temperature signal in the PLC system of backstage temperature collect module by data feedback holding wire 6, be converted to digital quantity by analog quantity.In case the temperature that thermocouple 5 collects surpasses setting value, PLC system in backstage can send instruction, with the aperture of raising suction opeing 2, thereby strengthens the exhausting amount, reduces the temperature in the reflection shield 3; Equally, if temperature is lower than setting value, then automatically reduce the aperture of suction opeing 2, reduce the exhausting amount, the temperature in the rising reflection shield 3 is guaranteed the temperature constant in the reflection shield 3.
