Baking oven: promptly enter drying tunnel behind the present automatic double surface gluer base material gluing and toast processing, bake out temperature can not be higher than the base material deformation temperature, so it produces the restriction that mainly is subjected to stoving time.
The mode of heating of baking oven has three kinds at present: 1) vapor line heating; 2) electrical heating (heating of far infrared plate or iodine-tungsten lamp heating); 3) send hot dry wind to baking oven.In order to discharge the steam that volatilizes in the glue, exhaust apparatus all is equipped with on drying tunnel top, generally is to adopt aerofoil fan outwards to bleed.Its objective is and utilize thermal convection principle to take away moisture content, and its process nature is together to discharge with cool ambient air heating back and with hot-air and steam that heat utilization efficiency is low, energy consumption is big.
Purpose of design of the present utility model is: avoid weak point of the prior art, design a kind of gluing evenly, rubberised layer is easy to control and heat utilization efficiency height, the little novel pressure sensitive adhesive tape production equipment of energy consumption loss.
Design of the present utility model is: novel pressure sensitive adhesive tape production equipment, it comprises and unreels glue spreader 1, gives hot frame 5, baking oven 9 and winder 11, unreel left end, the winder 11 that glue spreader 1 is positioned at baking oven 9 and be positioned at the right-hand member of baking oven 9 and all separable, and be equipped with one between glue spreader 1 and the baking oven 9 and give hot frame 5 unreeling, give hot frame and be the open frame structure, be equipped with 1～10 Far-infrared Heating plate 7 in the upper frame bottom of giving hot frame, be equipped with 1～5 exhaust fan 17 on the underframe of hot frame giving, support stick is positioned at and gives hot frame top, and adhesive tape 6 is positioned on the backing roll; The rubber-coated mechanism 4 that unreels in the glue spreader 1 is made of glue box 18, glue scraping plate 19, smoothing roller 20, back flow roll 21 and glue spreader 24, smoothing roller 20 and glue spreader 24 laterally are positioned on the frame that unreels glue spreader 1 and laterally are positioned on the same axis, back flow roll 21 is positioned to be put on the glue spreader frame, back flow roll 21 is positioned at the top of glue spreader 24 and vertically is positioned on the same axis with glue spreader, the frictioning face of glue scraping plate 19 touches mutually with the roll surface of even glue rod 20, and the glue in the glue box 18 soaks the roll surface of bag glue spreader 24; The direction of rotation of smoothing roller 20, back flow roll 21 and glue spreader 24 is identical and linear velocity is identical.Clearance t between back flow roll 21 and the glue spreader 24 is 0.5mm～3mm; The gap delta that smoothing roller 20 and glue spreader are 24 is 0.02mm～0.2mm; Base material 23 is 15 °～40 ° with the wrap angle sigma of glue spreader 24.The top of the Far-infrared Heating frame of baking oven 9 and below are equipped with 2～10 aerofoil fans 10.
1, glue spreader:
The painting method that this machine adopted as shown in Figure 2, glue spreader, back flow roll and smoothing roller are dragged by a cover transmission system by motor, the linear velocity on equidirectional rotation of three rollers and three roller surfaces is identical, regulate the gap delta between glue spreader and the smoothing roller, can control the thickness of rubberised layer, base material is having a wrap angle sigma (promptly coincide angle) to regulate the size that clearance t between back flow roll and the glue spreader can change the angle α that coincide on the glue spreader.The glue spreader rotation is taken glue on the roll surface to during gluing, because the reverse rotation effect of smoothing roller can make glue by δ uniformly attached on the glue spreader, base material is with the linear velocity reverse movement identical with glue spreader, because identical angle α is arranged, add certain force of strain, can will all be coated onto on the base material uniformly attached to the glue on the glue spreader.With the not influence of base material thickness variation of thickness of this gluing way rubberised layer, as long as three rollers are processed by required precision, the thickness of rubberised layer can be transferred to below 0.02 millimeter, and the unevenness of bondline thickness also can be controlled to below 0.005.
General standard adhesive tape bondline thickness is 0.02～0.03 millimeter, and the δ value can be adjusted to 0.06～0.08 according to gelatin concentration, and the inconsistency of δ value (being the depth of parallelism of glue spreader and smoothing roller bus) need be transferred in 0.01.To thickness is 0.03 millimeter base material, and the optimum value of the angle α that coincide is 20 °～30 °, and when base material thickness changes greatly, when both sides tension force was inhomogeneous, the angle can be suitably greatly, and when the base material mass ratio was better, the α angle can be suitably littler.Glue can be residual cause coating inhomogeneous to glue spreader when the α angle was too small, because the reverse gluing to excessive the causing of reverse resistance of the base material phenomenon of " skidding ", also can cause local bondline thickness to change, influenced the gluing quality when α angle is excessive.
This three rollers counter-rotating coincide and has overcome the various disadvantages in the coating technique against being coated with method, can obtain desirable coating effect.
