Abstract
The invention discloses a kind of new type hot-melt adhesive coating blade, be characterized mainly in that and have employed scraper and thermal source in the design of one, there is simple in construction, easy and simple to handle, integrate melten gel, insulation, defeated glue, the feature of frictioning.Owing to this is designed with the heat-conducting oil heating of flowing, scraper left and right temperature can be made consistent, PUR melts evenly, thus it is the most permanent to reach glue supply, the coating requirement that coating weight is consistent.Meanwhile, the PUR that electric-heating-wire-heating method can be avoided to cause because of overtemperature is aging and Yellowing.
Description
Technical field
The present invention relates to a kind of PUR coating blade integrating melten gel, insulation, defeated glue, frictioning.
Background technology
Along with improving constantly of people's environmental consciousness, in a lot of two interfaces needing bonding, the PUR of environmental protection is used the most widely.Especially in industries such as weaving face fabric, underwear material, footwear material, automotive trims, a kind of directly by the short route mode (can be described as thermal transfer coating) that is coated with after hotmelt melts in fast development.At present in this coating way, the heating and melting of glue, conveying, scraper coating are separate: PUR is transported to the glue conveying box with electric heating system by Melt Pump or extruder, again by glue conveying box along the axial back and forth movement of scraper, the PUR of fusing is transported between scraper and coated article, with the movement of coated article, PUR scratches on coated article.Present invention employs scraper and thermal source in one design, there is simple in construction, easy and simple to handle, integrate melten gel, insulation, defeated glue, the feature of frictioning.The conduction oil being designed with flowing heats scraping cutter hub, and dispensing area temperature can be made consistent, and PUR melts evenly, thus it is the most permanent to reach glue supply, and coating weight is coated with requirement uniformly.Simultaneously, it is to avoid electric-heating-wire-heating method, cause local overheating because heating wire surface temperature is too high, cause PUR aging and the phenomenon of xanthochromia.
Summary of the invention
The invention discloses a kind of PUR coating blade, its simple in construction, easy and simple to handle, integrate melten gel, insulation, defeated glue, frictioning, it is characterised in that mainly include following 8 big parts: scraper body, PUR input hole, heat conduction oilhole, PUR delivery outlet, wing, wing clamping plate, screw installing hole and screw.As shown in Figure 1, heat conduction oilhole is comprised on described scraper body, PUR input hole, PUR delivery outlet and screw installing hole, scraper body is processed into by special alloy steel 1Cr13, its external form is for carving type body, upper wide 30-40mm, lower wide 25-35mm, highly 50-70mm, depending on the visual coating width of length, Rhizoma Sparganii rounding.
Described heat conduction oilhole is through along the length direction left and right of scraper body, the diameter 10-15mm in hole.
Described PUR input hole, through along scraper body length direction left and right, parallel with heat conduction oilhole, a diameter of 15-25mm in hole, described PUR input hole is 25-35mm with the centre-to-centre spacing of described heat conduction oilhole.
. described PUR delivery outlet and input hole are through, the kernel of section horizontal line of its center and PUR input hole is in-30～30 ° of angles, a diameter of the 2 of PUR delivery outlet～3.5mm, uniform along the length direction of scraper body, cloth hole width determines depending on coating width, and the centre-to-centre spacing of adjacent holes is 30-60mm.
Described wing clamping plate are fixed on scraper body by screw；Described screw installing hole is uniform along scraper body length direction, cloth hole width determines depending on coating width, centre-to-centre spacing 60-120mm of adjacent holes, thread size is M4～M6*10, described screw mounting hole site is in the centre position of two adjacent PUR delivery outlets, to avoid PUR to form resistance after PUR delivery outlet exports during flow down, affect the uniformity of coating.
Its operation principle is:
The conduction oil of constant temperature is pumped into the circulation of conduction oil hole, improve the temperature of scraper and applying area to certain value, make residual heat melten gel in scraper melt, and guarantee to carry through extruder or Melt Pump that the PUR come is unlikely cooled makes colloid viscosity improve, cause application difficulties and irregular.The temperature of conduction oil determines according to the performance using PUR.
After the PUR in scraper is completely melted, by extruder or the pressure of Melt Pump, PUR is exported by PUR delivery outlet, under pressure and action of gravity, the PUR of fusing is downward to wing with the contact area of coated article, along with the movement of coated article, under the incision pressure of wing, PUR is applied to coated article surface uniformly.
Accompanying drawing illustrates:
The construction features of the present invention is described below in conjunction with the accompanying drawings.
Wherein:
Fig. 1 is PUR coating blade assembling figure.
Fig. 2 is that PUR coating blade embodiment attempts.
Detailed description of the invention
Examples below is used for further illustrating the present invention, it is to be understood that this embodiment cannot be used for limiting the scope of the invention.
