1) Dvojni valj lepilo premaz stroj.
The double-roll glue coating machine is mainly composed of upper and lower glue coating rollers and glue tanks. The lower part of the lower glue coating roller is immersed in the glue tank, and the glue of the upper glue coating roller is transferred by the lower glue coating roller. When the veneer passes between the two glue coating rollers, it contacts the glue coating roller so that the glue on the roller is coated on the upper and lower surfaces of the veneer. The amount of glue coating mainly depends on adjusting the gap between the upper and lower glue coating rollers and the pressure of the upper glue coating roller. The thicker and narrower the veneer, the greater the pressure of the roller on the veneer, and the smaller the amount of glue coating; conversely, the greater the amount of glue coating. The shape and number of grooves on the roller also affect the amount of glue applied. The height of the glue liquid in the glue tank should be 1/3 of the diameter of the lower glue coating roller. Too large or too small will affect the amount of glue coating.
2) trivaljni lepilo premaz stroj.
Slika spodaj prikazuje videz BS3313 trivalj lepilo premaz stroj. trivalj lepilo premaz stroj je dodati a stiskanje valj naslednji zgornji ali spodnji lepilo premaz valjček. količina lepila nanesena je določena z vrzeljo med lepilom premazom valjem in stiskanje valj. A stiskanje valj je nastavljeno z zgornje lepilo premaz valjček, in lepilo je dobavljeno z z lepilo črpalka skozi prez guma cev, in lepilo je shranjeno v utoru oblikovano v med lepilom premazom valjčkom in stiskalno valjčkom; a stiskalno valjčkom nastavljeno na naslednje spodnje lepilo premaz valj za dobava lepilo iz lepilo iz lepilo, in količina lepila uporabljena ni prizadeta po višini tekočine ravni v lepilu rezervoarju. Čeprav trivalj lepilo premaz stroj ima dobro lepilo premaz kakovost % 2c to lahko samo nadzor količina lepilo naneseno na eno stran% 2c tako to ni široko uporabljeno.
3) Štiri valje lepilo premaz stroj.
The figure below shows the appearance of the BS3426B four-roller glue coating machine. The four-roller glue coating machine is to add a squeeze roller next to the upper and lower glue coating rollers to control the amount of glue applied on the upper and lower surfaces of the single board respectively. The linear speed of the squeeze roller is 15% to 20% lower than that of the glue coating roller, which plays a role in scraping glue, and the gap with the glue coating roller is adjustable to ensure that the thickness of the upper and lower glue layers is uniform. The upper and lower glue rollers supply glue at the same time without interfering with each other. It is not easy to jump when applying glue. It is a widely used glue coating equipment.
Obstajata dva načina urediti lepilo stiskanje valji štiri valje lepilo premaz stroj. 1) zgornji in spodnji lepilo stiskanje valji so razporejeni na obe strani strani lepila premaza valja, in lepilo črpalka zaloge lepilo lepilo skozi skozi guma cev; 2) zgornji in spodnji lepilo stiskanje valji so oboje nameščeni na strani strani lepilu prevleki valju, in zgornji lepilo premaz valj je dobavljen z lepilo z lepilo, in spodnji lepilo premaz valj valj je dobavljeno z z lepilo za z lepilo rezervoar spodaj. Z drugačna razporeditev in lepilo dobava metode valji, njihove funkcije so tudi različne. Prvi ima enakomerno lepilo premaz in lahko shrani lepilo; slednji je primeren za situacije z relativno visoko produktivnostjo.
