Background technique

LNG is the abbreviation of English LNG Liquefied natural gas (liquefied natural gas).Main component is methane.LNG is colourless, tasteless, nontoxic and non-corrosiveness, and its volume is about with 1/600 of amount gaseous natural gas volume, and the critical temperature between the LNG gas-liquid is-186 ℃, belongs to ultralow temperature.

LNG automobile gas cylinder is as a kind of low-temperature heat-insulation pressure container, be generally the double-layer vacuum structure, inner bag is used for storing the LNG Liquefied natural gas of low temperature liquid, be wound around the multilayer heat insulation composite bed at its outer wall, make it have superpower heat-shielding performance, chuck between inner bag and urceolus is pumped into high vacuum simultaneously, jointly forms good adiabatic system.Wall wound insulation composite bed operation unusual key just so outside the tank, too tight easily fracture, too pine is easily wrinkling, does not reach the heat insulation requirement of insulation.At present, the overwhelming majority adopts manual wound insulation material, and efficient 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 that 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 detection sag, winding layer automatic feeding 3 and the middle transition roller 6 that increases of automatic winding apparatus 4.

Described frame 1 is established the 2-5 layer from top to bottom, can realize simultaneously the winding of the adiabatic composite bed of different lengths, saved the trouble of not stopping to change several adiabatic composite beds, can realize material loading No. one time, complete the winding of the adiabatic composite bed of inner bag of a plurality of length, save the time of reloading, alleviated labor strength.

It is the thin-wall stainless steel pipe manufacturer of long 2 meters of 20mm that described transition wheel adopts diameter, and two ends are supported by bearing support, and transition roller is close to adiabatic composite bed placement, is driven by adiabatic composite bed and rotates.

Embodiment:

A kind of LNG mounted gas cylinder isolation layer wind, comprise that 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, carry out rewinding by automatic winding apparatus 4, inductor 5 is positioned over adiabatic composite bed bottom detection sag, winding layer automatic feeding 3 and the middle transition roller 6 that increases of automatic winding apparatus 4.Transition roller 6 makes winding layer produce sag, forms tension force by the deadweight of winding layer.

The specific operation mode: the first step, adiabatic composite bed is placed on frame, cylinder liner is placed on automatic winding apparatus by the inner bag automatic feeding; Second step is undertaken adiabatic composite bed is carried out feeding by the winding layer automatic feeding; In the 3rd step, detect the sag of material by inductor, and feed back to the winding layer automatic feeding and carry out the speed adjustment; In the 4th step, cylinder liner rotates by automatic winding apparatus and carries out rewinding.

the cylinder liner automatic feeding: the Rationality relationship of this device design is to winding mass, at first motor selects adjustable speed motor to carry out feeding, increase transition roller in the middle of feeder and wind, winding material produces certain sag between feeder and transition roller, utilize sagging how many deadweights of winding material to produce the elasticity that certain tension force is controlled winding, winding material sag by the detection of tunable optical electric switch, control tension force, owing to surpassing the optoelectronic switch detection range when sag, illustrate that tension force is too small or excessive, thereby it is too fast or excessively slow to reflect feeding, this moment, photoswitc provided signal, control program carries out speed governing to the feeding motor immediately, make it reach state of equilibrium.Guarantee 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 the winding layer raw material are middle porose wound roll materials, must fix by mandrel, mandrel is detachably and must be connected fast with automatic feeding, adopts the stepless time adjustment motor that power source is provided, and this device handling speed is fast, the feeding speed adjustability is good, has played key effect for guaranteeing winding mass.

Automatic winding apparatus

This mechanism drives the cylinder liner rotation, and this mechanism's motor is selected stepper motor, and this motor characteristic feature is that on off control is convenient, starts and stops there is no inertia, and motion speed is even, and is strong to winding layer uniformity assurance property.Make itself and feeding mechanism harmony good.Gas cylinder clamps and adopts pneumatic chuck, clamps fast, and the return precision is high, and the clamping and release controllability is strong.

Controllability of the present invention is strong, and operation has realized oversimplifying most, constant product quality, and automaticity is high, and noise is low, and energy consumption is little.
