The specific embodiment
Like Fig. 1,2, shown in 3, a kind of solar energy backboard diaphragm coating apparatus comprises and introduces pressure roller 1, draw roll 3, guide roller 4, applicator roll 10 and coating lining roller 9; Applicator roll 10 lower ends are provided with and pass rubber roll 8, pass rubber roll 8 lower ends and are arranged in the glue groove 11, and the roll shaft 18 of said applicator roll 10 is provided with vibrations generator 16; One side of applicator roll 10 is provided with metering roll 12; Metering roll 12 limits are provided with metering roll cleaning scraper 13, and the opposite side of applicator roll 10 is provided with dodges guide roller 17, dodge guide roller 17 and connect cylinder 6; Cylinder 6 connects magnetic valve 120; Magnetic valve 120 jointing detecting sensors 40, joint detecting sensor 40 are used for detecting the coating joint signal and are transferred to magnetic valve 120, and said guide roller 17 two ends of dodging are fixed on the slide block 140; Slide block 140 is arranged on the line slideway 100, and line slideway 100 is fixed on the frame 19.Joint detecting sensor 40 adopts the ultrasound examination sensor.Applicator roll 10 limits are provided with the doctor roll 5 that is used to clear up glue.Vibrations generator 16 adopts the vibrations generator of frequency adjustable.
Coated substrate 2 is wherein introduced pressure roller 1 and draw roll 3 mutual extrusion coated substrates according to the operation of arrow direction indication, and draw roll 3 is active rotation when operate as normal, drives coated substrate and steadily sends into coating station.Coated substrate 2 through guide roller 4, dodge guide roller 17 and be pressed in and carry out gluing on the applicator roll 10, go out the entering next process through coating lining roller 9 then.
Because the required precision of coated product face coat must be evenly; So necessary stable and uniform of the speed of service of base material; In this structure,, reduced the base material speed of service error that driving-chain caused, can improve coating uniformity through adopting the structure of motor direct connection draw roll.Guide roller 4 mainly act as the guiding coated substrate move along the traffic direction that requires.
Pass rubber roll 8 and mainly act as the glue 7 in the glue groove that stirs, intercept the bubble in the glue simultaneously, uniform ingredients and bubble-free glue evenly are delivered to coating roll on 10 surfaces.
Rotating speed through gap between precision adjustment metering roll 12 and the applicator roll 10 and adjustment metering roll 12 makes the glue distribution layer thickness on the applicator roll 10 even.Metering roll 12 remained on surface glue are cleared up in mainly acting as of metering roll cleaning scraper 13, avoid residual glue to use influence and cured granulate to transfer to formed coating striped of substrate surface and particle point repeatedly.
After the joint 30 operation processes that produced when the coated substrate change of lap later stage are introduced pressure roller 1 and draw roll 3; Be installed in and send signal to magnetic valve 120 after draw roll 3 ultrasonic wave joint detecting sensor 40 afterwards detects joint; Magnetic valve 12 0 switches pressure directions; Control cylinder 6 pistons pulling joint is dodged guide roller 17 and is moved up, and makes coated substrate 2 away from applicator roll 10, thereby dodges automatically with realizing the adhesive tape position; The slide block 140 of dodging guide roller 17 two ends slides along line slideway 100, makes to dodge guide roller 17 and move up and down comparatively smooth.
Like Fig. 4, shown in 5; Drying baker comprises the casing of being made up of top box 510 and nowel 511, is provided with the coated substrate passage in the casing, symmetrical air inlet 55, intake stack 59, static pressure chamber 54, air supporting nozzle 56, far infrared lamp tube cover 57 and the far infrared fluorescent tube 58 of being provided with in top box 510 and the nowel 511; Air inlet 55 connects intake stack 59; Intake stack 59 connects static pressure chamber 54, and static pressure chamber 54 connects air supporting nozzle 56, and far infrared lamp tube cover 57 is set in the air supporting nozzle 56; Air supporting nozzle 56 forms gap nozzle with far infrared lamp tube cover 57 sidewalls, is provided with far infrared fluorescent tube 58 in the far infrared lamp tube cover 57.Top box 510 is provided with waste discharge mouth 53.Air supporting nozzle 56, far infrared lamp tube cover 57 and far infrared fluorescent tube 58 all are provided with 55 groups in top box and nowel.
Coated substrate 2 is by the operation of the diagram direction of arrow, and wherein the upper surface at coated substrate is attached with the solution (glue) that needs drying.Coated substrate 2 gets in the casing of being made up of top box 510 and nowel 511 under guiding roller guiding function; The solvent that is comprised in the solution of base material upper surface (glue) carries out volatile dry in drying baker; The part that the needs that comprised in the glue simultaneously solidify is evenly distributed on substrate surface, accomplishes the dry run of coating.
Air is about outside blower fan pressurization back gets into respectively through intake stack 59 in the static pressure chamber 54 in the drying baker; Wind forms to get into respectively behind the certain pressure in static pressure chamber 54 and forms pressure in the air supporting nozzle 56 once more; Because air supporting nozzle 56 forms gap nozzle with far infrared lamp tube cover 57 sidewalls in this structure, so wind evenly sprays from the air supporting nozzle under the effect of pressure.In the middle of this structure mid and far infrared fluorescent tube 58 is arranged on air supporting nozzle 56, therefore at the acting in conjunction of waiting to receive simultaneously after drying coated substrate gets into drying baker two kinds of drying modes, i.e. Far-infrared Heating and air-dry dual mode.Distinguished and admirable outer surface through the far-infrared lamp shroud has played the effect of cooling far infrared fluorescent tube and lampshade simultaneously, again air at room temperature is heated.The heating of far infrared fluorescent tube adopts upper and lower surface to heat simultaneously in the design, promotes drying efficiency.Air-flow from the slit ejection in the nowel plays the effect that holds up coated substrate simultaneously, has reduced material and has drawn wiping with other surfaces of solids, improves the surface quality of coated product.
Coated product a large amount of solvent vapo(u)r that after super-dry, volatilizees; If solvent vapo(u)r can not in time be drained the drying effect that greatly influences product; Therefore in the design, adopt and 53 pairs of solvent vapo(u)rs that volatilized of drying baker waste discharge mouth are set carry out continuous exhaust pneumatic wallop; Improve drying effect, cool off the lampshade of far-infrared tube simultaneously.
