Now each roller and each machine design feature are done specific descriptions.

Upper and lower corrugation roller is 45 ^#The thick-walled pipe of steel, tube wall upper edge axis direction is milled with C type corrugation, and the spindle nose at two ends is coaxial welded together with pipe, and suspending by rocking arm on the frame and eccentric shaft is fixed on the frame, and this structure is convenient to adjust the depth of parallelism and gap.

Upper and lower hold-down roller roller footpath below the corrugation roller is identical, structure is identical, all formed by spindle nose, roller, sleeve, two spindle noses of each roller are coaxial welded together with a roller, spindle nose is hollow, there is the step cylindrical of the diameter that varies in size the outside, and installation graphite bearing, travelling gear, sprocket wheel are used; Electrothermal tube is equipped with in the centre of hold-down roller, in order to corrugated board is heated in bonding process, plays the oven dry effect; It is triangle or 30 strip grooves of circular arc that the outer surface upper edge axis direction of roller is carved with bottom of trench, and an end of groove opens near till the roller end; The other end then opens to end face always, and the outside of roller is close to the roller face and is with one deck Steel Thin-Wall sleeve, and three sections of this status of sleeve left, center, right, every section contact position are to utilize different radius cylindrical steps and be plugged on together; The tube face is along having 270 through holes on nine circumferences perpendicular to axis direction, be evenly distributed with 30 holes on each circumference, this hole is a circular hole in the part near roller, the center, hole faces the groove on the roller, by sleeve then is the slot of semicircle for two here, with this spline structure the hole area on contact corrugated board surface is strengthened, air-breathing air blowing effect is more remarkable.

Then be to be square bar-shaped trough on the roller outer surface for preheat roll along the end that axis direction has ten millimeters of 24 dark eight mm wides equably, one end of groove only opens to apart from the end face of roller a distance, the other end is then one till the termination of roller, form gas circuit so that cooperate with the graphite distribution bearing of installing on the spindle nose, the roller outer surface divides three sections suits the sleeve that sheet metal is formed along axis direction; Have 24 through holes altogether on the surface on perpendicular to the circumference of axis, amounting on nine circumferences has 216 holes, and on the sleeve surface is that 2 millimeters hole is that two is the semicircle slot deeply; Toward deeply then being small sircle hole, the hole heart faces groove on the roller again, communicates with bar-shaped trough on the roller, forms gas circuit.

Sprocket wheel all is housed one end spindle nose of hold-down roller and preheat roll or gear carries out transmission; And the other end also all is equipped with graphite distribution bearing, and it is a cylinder, and is middle porose, coaxial being enclosed within on the spindle nose, with bearing face that the roller end face contacts on, with the corresponding place of roller groove, the bottom of trench that along the circumferential direction has certain depth is square groove; And the groove with 270 ° of angle of release length is an one, perpendicular to axis direction the straight-through groove of a vacuum noz(zle) is installed in the bearing outside; Be another body with the groove of 60 ° of length of angle of release equally, though the groove of it and 270 ° of length is not connected each other all on same circumference along circumference; This groove also is equipped with a suction nozzle on the direction perpendicular to axis of bearing outside, directly communicate with groove, and gas through the groove on the bearing, the eyelet of strip groove to the sleeve on the roller, has formed gas circuit by valve.In the course of work, vacuum noz(zle) is carrying out air-breathing with suction nozzle because of the pipeline that is being connected air pump always and is blowing, and graphite distribution bearing is motionless; Hold-down roller and preheat roll are in rotation process, when strip groove termination on the roller touches 270 ° of air-breathing grooves of length of graphite distribution bearing, cardboard and paper begin to be attracted on the roll surface, after covering air-breathing section of this section, can contact with the air inlet groove of 60 ° of length of graphite distribution bearing with that, suction nozzle is blown in gas circuit, blows the surface that corrugated board or paper break away from roller, continues to subsequent processing.

Glue spreader has two, and structure is identical.Glue is contained in the rectangular glue groove that sheet metal makes, and an end margin of trough has tabular hook and sliver, is convenient to trough is hung on the side plate.Parallel successively glue spreader, spreading roller and the glue scraping plate of being placed with in the groove; Glue spreader is that a heavy wall round steel pipe is done roller and two spindle nose coaxial welding form, roll surface is pressed with decorative pattern, be convenient to the glue coated on roll surface, and to be uniform-distribution with perpendicular to 22 of the axis of roller, bottom be square annular ditch groove on the surface, roll surface just is with into strips by the many annulars of cut-off rule like this, just can occurrence of large-area when gluing glue be pushed through the phenomenon at a place.Glue spreader is partly to be immersed in the glue groove, in rotation process, glue is taken up attached on the roll surface, for making glue evenly hang on the roll surface, with the parallel spreading roller that a light face is installed of glue spreader contact, it and the equidirectional rotation of glue spreader, but the rotating ratio glue spreader fast again about, it has played the glue-line that makes glue spreader and has acted on more uniformly; The rubber block of red copper long strip-board shape is housed in the middle of every groove of glue spreader simultaneously, and this plate all is through on the axle between glue spreader and spreading roller, and the glue that it can block in the glue spreader groove overflows.For the glue on the spreading roller can be scraped off in time, other establishes one and tightly contacts the glue scraping plate of parallel placement with it, it is a rectangular vulcanite plate, both sides accompany one wide one narrow supporting plate and baffle plate, with bolt the vulcanite plate fixedly is clipped in the middle, the parallel contact of glue scraping plate and against direction of rotation frictioning in following groove of roller with spreading roller, the glue scraping plate two ends are fixed on the frame; Spreading roller and glue spreader are chain gear transmission, middle adjusted with distend wheel, preventing in the time dead of glue spreader between two corrugated papers or paper because and the gap between hold-down roller or lower corrugated roller improper and glue is coated on hold-down roller and the lower corrugated roller; Simultaneously also be that elimination is improper because of the gap of glue spreader and spreading roller, and it is inhomogeneous that the kiss-coating layer takes place, thereby influence product gluing inequality, bonding not firm phenomenon.
