C, under the filtration members 18 of drum paper trunk molding machine 10 and the collective effect of high-pressure plaster-spraying implement 12, relative to tradition Drum paper trunk formation system made of layer structure drum paper trunk, this programme drum paper trunk formation system made of drum paper trunk Body is because high pressure effect is dispersed structure, and since the aperture of the filter opening of filtration members is very small, most of staple fiber can not Outflow with water, but be stranded in forming cavity across filter opening, can connection between long fibre put up a bridge so that the toughness of drum paper Increased with rigidity.

D, since the aperture of the filter opening of filtration members 18 is very small, so that the surface of molding bulging paper trunk nor ordinary light are sliding, Increase the aesthetics of bulging paper trunk.

E, the smart filtration of filtration members 18 makes without solid suspension and pigment in waste water, so that the waste water generated is not required to By any purified treatment, reduce the processing cost of waste water.

F, because the wood fiber material for making drum paper trunk needs stringent selection in severe cold area by growing all the year round, cell The timber of concentration is not easy to cultivate as paper pulp raw material, this timber, if largely cutting down the timber for making bulging paper trunk, no Ecological environment can be only destroyed, and is unable to satisfy the lasting supply of timber.Because the drum paper trunk of the utility model forms system System can make slurry save 30% or more, therefore may make the felling quantity of the trees for manufacturing slurry also reaches to greatly reduce, Environment is protected, and enables and continues to supply for making the trees of slurry.

Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
