Background technique
LNG is the abbreviation of English LNG Liquefied natural gas (liquefied natural gas).Main component is methane.Colourless, tasteless, the nontoxic and non-corrosiveness of LNG, the critical temperature between its volume is about with 1/600, LNG gas-liquid of amount gaseous natural gas volume is-186 DEG C, belongs to ultralow temperature.
LNG vapour vehicle gas cylinder is as a kind of low-temperature heat-insulation pressure container, be generally double-layer vacuum structure, inner bag is used for storing the LNG Liquefied natural gas of low temperature liquid, multilayer heat insulation composite bed is wound around at its outer wall, make it have superpower heat-shielding performance, chuck simultaneously between inner bag and urceolus is pumped into high vacuum, the adiabatic system that common formation is good.Wall wound insulation composite bed operation is with regard to key very so outside the tank, and too tight easily fracture, too pine is easily wrinkling, does not reach the requirement of insulated heat.At present, the overwhelming majority adopts manual wound insulation material, and efficiency is low, and man-hour is long, is unfavorable for industrialized production.
Summary of the invention
The invention solves the problem that the adiabatic composite bed of a kind of LNG mounted gas cylinder inner bag is wound around, technological scheme is: the adiabatic composite bed wind of a kind of LNG mounted gas cylinder, comprises frame 1, cylinder liner automatic feeding 2, winding layer automatic feeding 3, automatic winding apparatus 4, inductor 5, transition roller 6 form; Adiabatic composite bed carries out feeding by winding layer automatic feeding 3, carries out rewinding by automatic winding apparatus 4, and inductor 5 is positioned over adiabatic composite bed bottom and detects sag, increases transition roller 6 in the middle of winding layer automatic feeding 3 and automatic winding apparatus 4.
Described frame 1 establishes 2-5 layer from top to bottom, the winding of the adiabatic composite bed of different lengths can be realized simultaneously, eliminate the trouble not stopping to change several adiabatic composite bed, a material loading can be realized, complete the winding of the adiabatic composite bed of inner bag of multiple length, save the time of reloading, alleviate labor strength.

embodiment:
A kind of LNG mounted gas cylinder isolation layer wind, comprise frame 1, cylinder liner automatic feeding 2, winding layer automatic feeding 3, automatic winding apparatus 4, inductor 5 form, adiabatic composite bed carries out feeding by winding layer automatic feeding 3, rewinding is carried out by automatic winding apparatus 4, inductor 5 is positioned over adiabatic composite bed bottom and detects sag, increases transition roller 6 in the middle of winding layer automatic feeding 3 and automatic winding apparatus 4.Transition roller 6 makes winding layer produce sag, forms tension force by the deadweight of winding layer.
Specific operation mode: the first step, is placed in frame by adiabatic composite bed, is placed on automatic winding apparatus by cylinder liner by inner bag automatic feeding; Second step, is undertaken adiabatic composite bed to carry out feeding by winding layer automatic feeding; 3rd step, detects the sag of material by inductor, and feeds back to winding layer automatic feeding and carry out speed adjustment; 4th step, cylinder liner is rotated by automatic winding apparatus and carries out rewinding.
Cylinder liner automatic feeding: the Rationality relationship of this apparatus design is to winding mass, first motor selects adjustable speed motor to carry out feeding, transition roller is increased in the middle of feeder and wind, winding material produces certain sag between feeder and transition roller, the sagging how many deadweight of winding material is utilized to produce the elasticity that certain tension force controls winding, the winding material sag detected by tunable optical electric switch, control tension force, owing to exceeding optoelectronic switch detection range when sag, illustrate that tension force is too small or excessive, thus it is too fast or excessively slow to reflect feeding, now photoswitc provides signal, control program carries out speed governing to feeding motor immediately, it is made to reach state of equilibrium.Ensure that isolation layer is wound around evenly.
Winding layer automatic feeding: the adiabatic composite bed of rolling is fixed on mandrel, pneumatic Quick-clamped chuck and top tail top clamping mandrel, because winding layer raw material are middle porose wound roll materials, must be fixed by mandrel, mandrel detachably and must be connected fast with automatic feeding, and adopt stepless time adjustment motor to provide power source, this device handling speed is fast, feeding speed adjustability is good, for ensureing that winding mass serves key effect.
Automatic winding apparatus
This mechanism drives cylinder liner to rotate, and this mechanism motor selects stepper motor, and this motor characteristic feature is that on off control is convenient, and starting stopping does not have inertia, and motion speed is even, strong to winding layer uniformity guarantee property.Make itself and feeding mechanism harmony good.Gas cylinder clamping adopts pneumatic chuck, and fast, return precision is high, and clamping and release controllability is strong in clamping.
Controllability of the present invention is strong, and operation achieves to be simplified most, and constant product quality, automaticity is high, and noise is low, and energy consumption is little.
