Abstract
The dry tubular fiber gluing process includes conveying fiber with one sealed pressure from the fiber drying material bin to the gluing tube, mixing dry fiber with blower conveyed air, atomizing glue the gluing pump provides with one atomizer to form glue liquid conveyed to the gluing tube, and mixing dry fiber with glue liquid in the tubular gluing machine while conveying. The present invention completes the gluing and conveying simultaneously, and has low glue consumption, low power consumption and no surface glue spot on the plate.
Description
Technical field
The present invention relates to a kind of applying glue to fibers technology on the medium density fiber board assembly line and application apparatus of this technology of being applied to.
Background technology
The adhesive cost of the thermal power consumption in the drying process, applying glue operation is a constituent important in the medium density fibre board (MDF) production cost.
In existing medium density fibre board (MDF) production-line technique, glue-applying technique has two kinds, i.e. wet method pipeline glue-applying technique and glue mixing technology.Wet method pipeline glue-applying technique is " fiber separation-applying glue-drying " technology just, in wet method pipeline applying glue process, there is adhesive precuring problem because of high temperature drying, so can only adopt lower baking temperature, this has just reduced the utilization ratio of dry heat energy and has increased dry power consumption; The problem that all unavoidably can have some precuring and permeate in fiber in the fiber drying process owing to adhesive, so this processes expend glue amount again is generally than the high 15%-20% of glue mixing technology.Glue mixing technology is also referred to as " fiber separation-drying-spray glue mixing " technology, and this mechanical glue mixing mode tends to owing to mechanical agitation the bump of fiber sizing be formed the fiber sizing micelle, produces gum spot at plate surface, causes the production board quality to descend and is difficult to extensive employing.
Summary of the invention
The object of the invention provides a kind of dry tubular gluing process and device, and it can prevent to occur on the fiber sizing gum spot when reducing resin added.
Technical scheme of the present invention is: a kind of dry tubular gluing process, and it comprises the steps,
1., dried fiber is transported to the applying glue pipeline by conveying device;
2., in described applying glue pipeline, carry air, dried fiber is mixed in the applying glue pipeline greater than 1: 1 concentration with mass ratio with the air that transfers out from blower fan by blower fan;
3., adhesive is formed glue by atomising device atomizing, under the effect of described blower fan, dried fiber is mixed formation fiber sizing product on conveying limit, applying glue pipeline the inside with glue.
A kind of dry tubular gluing device, it comprises the conveying device with pressure isolation effect, the applying glue pipeline that is connected with described conveying device, described applying glue pipeline is provided with atomising device.
The present invention compared with prior art has following advantage: the dry tubular gluing The Application of Technology can prevent to produce micelle on the fiber sizing, has avoided reducing problem by the caused quality of the gum spot of plate surface; And solved adhesive precuring problem based on the technology of the dry after dryer sizing of elder generation that dry tubular gluing process adopted, significantly reduced the resin added on the medium density fiber board assembly line, and can solve the precuring problem of adhesive in dry run, baking temperature can increase substantially, reduced the demand of drying medium, the power consumption of dry hear rate and drying medium also greatly descends, thereby reaches the purpose of saving energy and reduce the cost, saving cost that medium density fibre board (MDF) is produced.
Description of drawings
Accompanying drawing 1 is a process flow diagram of the present invention;
Wherein: 1, dried fiber feed bin 2, conveying device 3, blower fan 4, applying glue pipeline 5, atomising device; 6, adhesive 7, applying glue pump.
The specific embodiment
Shown in accompanying drawing 1, a kind of dry tubular gluing process, it comprises the steps,
1., dried fiber is transported to applying glue pipeline 4 by conveying device 2;
2., in described applying glue pipeline 4, carry air, dried fiber is mixed in applying glue pipeline 4 greater than 1: 1 concentration with mass ratio with the air that transfers out from blower fan 3 by blower fan 3;
3., adhesive 6 is formed glue by atomising device 5 atomizings, under the effect of described blower fan 3, dried fiber is mixed formation fiber sizing product on conveying limit, applying glue pipeline 4 the insides with glue.
The present invention also provides a kind of dry tubular gluing device, it comprise conveying device 2 with pressure isolation effect, with the applying glue pipeline 4 that described conveying device 2 is connected, described applying glue pipeline 4 is provided with atomising device 5.
As shown in Figure 1, be transported to air delivery pipe 4 from the dried fiber in the dried fibres feed bin 1 equably by conveying device 2, the air that dried fiber and blower fan 3 carried with high concentration than mixing, the adhesive 6 that is provided by applying glue pump 7 is also sprayed in the applying glue pipeline 4 by the back glue that forms of atomising device 5 atomizings, dried fiber mixes with the glue of being exported by atomising device 5 under the effect of blower fan 3, and in the pipeline sizing applicator, be transferred with the discharge pressure that is higher than 10000Pa, finishing the process of even applying glue of fiber and conveying simultaneously, and the fiber of even applying glue is delivered to subsequent processing.
Conveying device 2 can adopt tube-type spiral conveyer or rotary valve dispenser, because tube-type spiral conveyer and rotary valve dispenser are the equipment that adopts usually in this area, so be not described in detail at this.And in the preferred embodiment that the present invention adopts usually, conveying device 2 adopts tube-type spiral conveyer, it can play the pressure isolation effect in the process of carrying dried fiber, preventing dried fiber, and can realize the purpose of even discharging owing to the high pressure effects in the applying glue pipeline 4 pass back into a kind of fiber feed bin.
