China's polyethylene green house film production almost is to put down to squeeze into blow molding technology, and the traditional way of drip fog dispersal performance of improving the canopy film is to add non-drop fog-eliminating agent in the canopy film; But the drip fog dispersal function lasting period of the canopy film that this method is produced is short and can reduce canopy film strength and weather resisteant energy.It is a kind of effective means that discovered in recent years applies the long-acting anti-dropping antifogging agent at the inner surface of canopy film, not only can prolong the drip fog dispersal lasting period of canopy film significantly and reduces production costs, and can not reduce canopy film strength and weather resisteant energy.Present domestic agricultural canopy film manufacturing enterprise mainly attempts on-line spray technology from following two aspects: extrude the online on-line spray technology of drying rolling again from the outer surface spraying of canopy film of upwards blow molding 1.; 2. extrude downward blow molding, spray pipe is drawn at the place at the blowing head, radially continuously liquid non-drop fog-eliminating agent quantitatively is sprayed on film after the typing with shower nozzle from film bubble inside center on, and make shower nozzle with the film bubble size adjustment on-line spray technology of control automatically.These two kinds of methods or increasing production site increase drying equipment; Or change original production technology fully.Fund input is big, is difficult to promote.
Summary of the invention:
At China's polyethylene green house film production almost is the flat blow molding technology of squeezing into, and on-line spray technology reforming scheme fund input at present is difficult to the present situation promoted greatly, the invention provides a kind of online rotary spraying in films technology and device.It is characterized in that blowing the cross-head upper shaft to the rotary spraying machine host is installed flat squeezing into, mechanical arm radially is installed on the rotary spraying machine host, elevation and subsidence regulating device is installed on the mechanical arm, nozzle is installed on the elevation and subsidence regulating device, outside the film bubble, high pressure airless spray equipment and control device are installed, the function masking liquid are transported to nozzle by pressure piping; Regulate the speed of pressure, spraying swath, flow or the rotation of rotation main frame of the distance of the nozzle be installed on the mechanical arm and film bubble inwall or spray coating liquor respectively, realization is to the even coating functions masking liquid of body surface; The position of nozzle is installed in more than the cooling line of film bubble, and passes through the position of elevation and subsidence regulating device adjustable nozzles, at least one highly pressurised liquid conveyance conduit and at least one group of supply line of installing vertically on the handpiece body of commentaries on classics flush coater main frame.The rotary spraying machine host is made up of swivel joint, variable-frequency motor and turbine and worm transmission case, circuit rotary connector and electric expansion bar.
Be characterized in: 1. fund input is little; Need not change the existing flat blowing production technique of squeezing into; Need not increase production site; 2. under the online production situation, in film bubble inner face Rotating with Uniform coating functions masking liquid on the cooling line.
The technical scheme that technical solution problem of the present invention is adopted is: this device is made up of three parts: 1. rotary spraying machine host, 2. mechanical arm, 3. high pressure airless spray equipment; Original head is if any interior device for cooling, and the post of earlier it being bled blocks suitably exceeding, and builds the platform of a size less than port mould diameter, again with rotary spraying machine host side's mounted thereto central authorities.Do not have interior device for cooling as former head, then the rotary spraying machine host can be installed in the central authorities of mouthful mould.Nozzle height is more than the cooling line of film bubble; Film is extruded the back uniform motion that makes progress under the traction of hauling machine, form columniform airtight film bubble above the mouth mould.Start this device this moment, the nozzle of rotary spraying main frame is in the rotation of film bubble inner face, adjust the flexible of mechanical arm, spray coating liquor is coated in the film surface that moves upward in right amount equably, if any interior device for cooling, utilize the moisture in the waste heat evaporation spray coating liquor in the film bubble, coldly extract hot and humid gas out the film bubble by interior.As do not have interior device for cooling and then the function masking liquid is retained in the film.
Technological core of the present invention is the rotary spraying machine host, and this main frame is made up of swivel joint, variable-frequency motor and turbine and worm transmission case, circuit rotary connector and electric expansion bar.Reasonably solved the technical problem that high pressure painting liquid, circuit line are connected, carry to the high speed round end by stationary end.Rational in infrastructure, rotation is steady, and rotating speed is adjustable.The nearly film end of at least two mechanical arms is respectively installed a shower nozzle that nozzle is outside, and mechanical arm can be flexible simultaneously vertically, and the distance of shower nozzle and film is adjustable arbitrarily.At least one high pressure airless spray equipment is connected with the rotary spraying machine host, and flow is adjustable.Spraying swath is adjustable, adjustable in pressure.
Beneficial effect:
1. owing to flow, spraying swath, the spray distance of rotary speed, hydrojet, all can adjust arbitrarily,, can not produce the spraying dead angle so can satisfy the on-line spray of different specification size film;
2. be the high-pressure airless rotary spraying owing to what invent employing, avoided the problem of spray coating liquor bounce-back fully, coating is more even than other spraying method, can not waste spray coating liquor.Can not change original constant voltage in the film bubble.
3. because 1,2 beneficial effect, effectively solved because the excessive problem that the film bubble can't inflation when the trickling downwards of film bubble inwall surpasses the cooling line of spray coating liquor, so need not change the upwards production technology of blowing, need not increase production site, fund input is less, is particularly suitable for the on-line spray transformation of the existing canopy membrane production equipment of China.
