Abstract
The invention discloses a constant temperature control cabinet for a cooling roller for a printing unit, relating to the technical field of printing equipment. A circulating water pump internally exchanges heat with the interior of a control cabinet body through a pipe wall; a circulating fan is primarily cooled; a desired constant temperature is set autonomously; a control device can be used for comparing the acquired real-time temperature with the set desired temperature after being adjusted; if the real-time temperature is higher than the set temperature, a refrigerator is powered on, and the real-time temperature, namely the temperature acquired by a temperature sensor is generally displayed on a Nixie tube display circuit; the temperature can be subjected to display switching if people want to display the set expected temperature, and the desired temperature can be displayed on a display. According to the constant temperature control cabinet for the cooling roller of the printing unit, the electric energy can be saved via effluent cooling, and online temperature detection and automatic constant temperature adjustment can be achieved.
Description
Technical field
The present invention relates to printing equipment technical field, be specifically related to printing unit chill roll constant temperature control box.
Background technology
Blown film printing unit is applicable to the plastic sheetings such as blown low density polyethylene (LDPE) high density polyethylene (HDPE) (HDPE) linear low density polyethylene (LLDPE) (LLDPE), is widely used in the civilian and industrial packagings such as food, clothes, refuse bag, plastic bag.Low-density polyethylene film generally adopts blowing and curtain coating two kinds of techniques to make.The thickness of curtain coating polyethylene film is even, but due to price higher, there be limited evidence currently of uses.High density polyethylene (HDPE) is high, the nonpolar thermoplastic resin of a kind of degree of crystallinity.Linear low density polyethylene (LLDPE) is true qualities, cylindric or oblate shape particle, and the size any direction of particle should be 2-5mm, and tramp metal, mechanical admixture are not structurally different from general low density polyethylene (LDPE), because there is not long-chain branch.
When calendered film or sticking tape coating, when finished product rolling in order to shrink the distortion caused when reducing hot material cooling, before rolling, making it lower the temperature by chill roll material reach the distortion reducing material.Chill roll is positioned at the roller of roll web drying device back, for the temperature of roll web being reduced to the solidification temperature of heat fixed type ink.
Along with making constant progress of World Science technology, the advanced technology such as electrical control and automation is in the application of printing machinery technical field, domestic printing mechanism manufacturing technology, mode obtain develop rapidly, this service behaviour of printing machine and scientific and technological content are had significant raising, and the scope of application and cited field have also been obtained expansion.
Because print speed printing speed is very fast, material film surface printing ink does not have drying, so printing rear material film must be allowed again before lower printing of the same colour to carry out drying through high temperature oven, but, because any material all exists the characteristic of expanding with heat and contract with cold, material film surface temperature after drying baker improves to cause expects that film heat rises, if now carry out printing the appearance that will cause the problem such as register trouble, picture and text distortion.After oven drying device, need installation cooling device for this reason, for cooling the material film with higher temperature of drying, make high temperature material film carry out lower printing of the same colour before be returned to of the same colour printing time temperature, i.e. room temperature.Chill roll is the important composition parts of printing machine, and its effect cools the material film after oven drying with high surfaces temperature.The cooling performance of chill roll directly has influence on the quality of printing, the tension stability of chill roll structural behaviour impact material film and chromatography precision.
Temperature controls the process control making often to run in industrial processes, and particularly in the industry such as metallurgy, chemical industry, building materials, food, machinery, oil, have very important effect, the control effects of its temperature have impact on product quality.Microcomputer is utilized to carry out the technology of observing and controlling to temperature, also just thereupon raw, and obtain growing and perfect, more and more reality goes out its superiority.
The outer chill roll of Current Domestic generally adopts the traditional structure of water injection type, and the shortcoming of this kind of structure is that water content is many, and temperature is constant temperature not, and heat transfer efficiency is low, and water resource waste, causes register trouble, printing images distortion.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, the printing unit chill roll constant temperature control box providing a kind of structure simple, reasonable in design, easy to use.
For achieving the above object, the technical solution used in the present invention is: it comprises control box-like body, water tank, circulating water pipe, circulating fan, refrigeration machine, temperature sensor, control device; The top of described control box-like body is provided with water tank and control device; The inner side edge of described control box-like body is provided with some circulating water pipes; Described circulating water pipe one end is connected with water tank; Described control casing bodies top is provided with circulating fan; Described control box-like body inner bottom part is provided with refrigeration machine; The described intrinsic chill roll of control casing is provided with temperature sensor; Described temperature sensor is connected with control device; Described control device comprises, single-chip microcomputer, digital pipe display circuit, temperature cooling circuit, reset circuit, temperature setting circuit, temperature collection circuit, clock oscillator are connected with single-chip microcomputer respectively; Described single-chip microcomputer is connected with digital pipe display circuit and temperature cooling circuit respectively; Described temperature cooling circuit is connected with refrigeration machine, and temperature collection circuit is connected with temperature sensor.
As preferably, described temperature sensor is digital sensor.
As preferably, described control device is also provided with warning device; Described warning device is connected with single-chip microcomputer.
When the present invention operates, first, by tube wall and the heat exchange of control casing body interior in circulating water pipe, and the preliminary cooling of circulating fan, the thermostat temperature of sets itself expection, regulate rear control device the expection temperature gathering real time temperature and the setting come to be compared, if real time temperature opens refrigeration machine than design temperature higher position, what digital pipe display circuit showed usually is real time temperature, namely the temperature that temperature sensor collection is next, if want the desired temperature showing people's setting can carry out display to switch, at this moment display will show desired temperature.
After adopting said structure, the beneficial effect that the present invention produces is: printing unit chill roll constant temperature control box of the present invention, through going out cooling, electric energy can be saved, realize on-line checkingi and the automatic regulating thermostatic of temperature, the present invention have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
