A kind of compounding machine for the preparation of hot melt adhesive wall paper
The present invention relates to the composite production device of a kind of fabric and hot melt net, refer in particular to a kind of gum compounding machine of hot melt adhesion wall cloth.
along with the raising of environmental requirement, in fabric field of compounding, solvent-free hot melt adhesive material is more and more accepted and is applied.Hot melt adhesive film and hot melt net, as the staple product of hot melt adhesion material, because of the convenience of its application, are more subject to the welcome in market.Current hot melt adhesive film or hot melt net and fabric carry out the common method of compound, are face cloth fabric and hot melt adhesive film or hot melt net material to be transported to the thermal treatment zone simultaneously carry out heating pressurization compound.But due to PUR product be heated after hot sticky performance, when carrying out the independent laminating production of face cloth and hot melt adhesive film or hot melt net (we are referred to as two-in-one), while there will be hot melt adhesive film or hot melt net one side and adhering fabric, another side can the problem of bonding parts.For solving it, existing equipment de-sign is taked with being with the antiseized conduction band of Teflon or band release liners to isolate.In actual production, hot melt adhesive film and hot melt net contact with the Teflon conduction band of heat also has bonding force.So on the one hand for making nethike embrane melting produce bonding force, Teflon band is heated, on the other hand, for making the nethike embrane of hot melt state be separated with Teflon band, a Teflon band also to be had to force cooling procedure.Like this, not only increase the length of Teflon conduction band, the contradiction of heating and cooling simultaneously, makes speed of production be restricted, also wastes energy.Add the restriction of the problem such as the width of the joint of conduction band, conduction band, the sideslip of conduction band, speed of production and product quality are greatly affected.As isolated by release liners, solving bonding parts problem, but adding cost, also increasing operation easier, especially to the hot melt net product not with release liners base, a kind of waste and the disagreeableness mode of production of environment especially.
The hot melt adhesion wall cloth of wide cut is produced, because of the particularity of used hot melt adhesive film or hot melt net performance, and wide cut Teflon conduction band cause equipment and technology bottleneck, do not have the release liners of more than 1.6 meters of wide cuts to splice in the market, make above-mentioned phenomenon more serious.

detailed description of the invention
technical solution of the present invention is: the face cloth as drapery passes through debatching deviation correcting device and front operating platform, be coated on after expander flattens with certain speed running, be in advance passed into heat-conducting oil heating to the first preheat roll of design temperature and the second preheat roll surperficial, face cloth is preheating to uniform temperature.Then by the contraction of bracket action cylinder, bracket is rotated counterclockwise around carriage turns axle, form bracket to tilt to the second preheat roll, make to be placed in nethike embrane spool on bracket and nethike embrane volume under gravity, roll along carrier tilt direction, until the nethike embrane volume on nethike embrane spool is close to the second preheat roll that Surface coating has face cloth.Under the frictional force of face cloth being coated on the second preheating roll surface and the effect of heat bonding power, drive nethike embrane spool to rotate, realize the automatic debatching of nethike embrane volume, and nethike embrane is flattened be layed onto cloth surface, face in advance.With the running of the second preheat roll, face cloth and the pre-combination product of nethike embrane are transported to the pressor areas that the chill roll that pressurizeed by pressurized cylinder and the second preheat roll formed and carry out pressurization compound, form hot melt adhesion wall cloth.Finished product wall cloth, through rear operating platform, enters winding system and carries out rolling.
Face cloth is first heated by preheat roll by the present invention, then by the temperature conduction of face cloth, carries out pressurization compound by after the nethike embrane be layed onto on the cloth of face progressively melting.
Nethike embrane spool of the present invention is laid on bracket, and bracket can carry out clockwise with the action of bracket action cylinder around bracket axle and rotate counterclockwise, and the nethike embrane volume be enclosed within nethike embrane spool can be contacting and separating with the second preheat roll.Under improper production status, state is stretched out at bracket action cylinder place, and nethike embrane is separated with the second preheat roll.During normal production, bracket action cylinder place contraction state, makes nethike embrane roll up and directly contacts with the face cloth being coated on the second preheat roll surface, realize the smooth debatching of nethike embrane.The advantage directly contacting debatching with face cloth is that nethike embrane and face cloth realize zero distance conveying, avoids the tension force produced in the nethike embrane long-distance sand transport process to strain sensitive and shrinks and wrinkling problem.
Chill roll of the present invention passes into cooling water and forces cooling, and during to solve continuous seepage, chill roll is caused temperature rise by the second preheat roll heat transfer, produces udnesion o omentum pressure roller phenomenon.For reinforced anti-adhesion effect, chill roll is also by surface treatment, and these process comprise: mirror process, painting Teflon, coated Si glue-line.
When the present invention considers that wall cloth is constructed, metope is hackly, more firmly bond to make wall cloth and wall paper, the surface of chill roll can be passed through exasperate process or engraving reticulate pattern, concave point, salient point or other decorative patterns, the surface with glue of the thermal bonding wall cloth produced is made to have certain roughness, when guaranteeing thermal-adhering, PUR more firmly can infiltrate metope, increases firmness.
