Besides, a refining slot 30 and a feeding channel 29 are arranged between the coater lower body 23 and the coater upper body 26. The coater lower body 23 is provided with a feed inlet 21. Vertical to the feed inlet 21, a refining hole 33 is provided along the coater lower body 23 with both ends plugged. Branch channels connected with the feeding channel 29 are provided along the refining hole 33 with equal interval. The closed shim plate 24 is door or comb shaped, and can be made into articles of different width or with interval strips coasting. The utility model can make use of thermoplastic material to coat products of high quality directly without drying, and it is energy saving and of simple structure.
Description
The utility model relates to the coating apparatus of adhesive material and coating, especially a kind of spreader of thermoplastic material-coated machine.
Adhesive material and coating are widely used in all kinds of printings such as paper, cloth, plastic sheeting, paper tinsel, pack, build the coated of chemical product, as adhesive label, adhesive tape, composite membrane etc.
Traditional coating machine mainly uses the coating and the adhesive of solvent-borne type and water-based, uses roll-type, scraper type spreader to carry out opening coating, have toxicity, high energy consumption, equipment volume greatly, problem such as inefficiency.The coating material that the thermoplastic material-coated machine uses is thermoplastic.Thermoplastic normal temperature for solid, is flow regime down during heating, thereby need not the technology that heating, drying is removed solvent after the coating.Only need to add necessary plasticising, tackifier.Thereby the thermoplasticity coating machine to have a coating process easy, reasonable, drying-free equipment is saved energy consumption, and is pollution-free, do not have advantages such as inflammable and explosive danger.The thermoplastic material-coated machine primary structure and the course of work and traditional coating machine basically identical, as shown in Figure 1, one of its main distinction is spreader.The primary structure of thermoplastic material-coated machine as shown in Figure 1 and Figure 2.Need substrates coated 2 to be contained on the unwinding device 1, through guide roller 3, adjust roller 4, on coating backing roll 6, be wrapped on the wrap-up 14 through reverse anti-sticking roller 8, carry-over pinch rolls 10, adjustment roller 13 then, need laminated base material 11 to be contained on two unwinding devices 12 through guide roller 3.Adjust spiral shell 9, walk around laminated roller 7 and to be coated with gum base materials 2 laminated and finally on wrap-up 14.The spreader 5 of coating thermoplastic material is installed in a side of coating backing roll 6.
The purpose of this utility model provides a kind of spreader that is applicable to the thermoplastic material-coated machine.
The utility model is achieved in that the spreader of thermoplastic material-coated machine comprises spreader lower body, spreader upper body.Spreader lower body and spreader upper body are long prism.The spreader lower body have one with vertical vertical charging aperture.Vertical with charging aperture, the spreader lower body longitudinally has a refining hole.The two ends shutoff of refining hole is communicated with charging aperture.Equidistantly have the branched bottom that communicates with the refining hole along the refining hole.Branched bottom be opened on spreader upper body adjacent planar on.The flow adjusting lever is housed on the branched bottom.Be processed with feeding channel and refining groove longitudinally between coating body upper body and coating body lower body.One end of feeding channel is connected with branched bottom, and the other end is connected with the refining groove.The two ends shutoff of refining groove.The spreader lower body is connected with body and function fastening bolt on the spreader.A sealing backing plate is arranged between spreader lower body and the coating upper body.
Spreader lower body and spreader upper body can be two bodies, connect and compose with screw.
Feeding channel and refining groove can be opened on the spreader upper body, or open on the spreader lower body.
The flow adjusting lever can with the coaxial setting of branched bottom, also can vertically with branched bottom be provided with.Be equipped with the O RunddichtringO on the flow adjusting lever.The size of the degree of depth control branched bottom opening that screws in by the flow adjusting lever with the flow adjusting lever of the coaxial setting of branched bottom, the flow that how much changes branched bottom that overlaps with branched bottom by the passage of change on it with the vertically disposed flow adjusting lever of branched bottom.
The sealing backing plate is shape or comb shape.
During work, melt in the glue case under the pressure effect of high viscosity thermoplastic fluid at delivery pump of fusion and enter charging aperture and refining hole through flexible pipe, preliminary therein even the pressure.Branched bottom and the feeding channel of thermoplastic after preliminary even pressure the through being equally spaced enters the refining groove and carries out even pressure of second step.In the opening that twice even sizing material of pressing just can be formed by the sealing backing plate equably, extrude and be coated with backing roll and cooperate and finish coating process.
