Abstract

The utility model discloses a double-side hot melt pressure-sensitive adhesive tape coating device. The double-side hot melt pressure-sensitive adhesive tape coating device comprises two groups of single side coating device (20 and 50) with same structures, positioning rolling wheel (2 and 10), releasing shaft (1 and 9), a coiling shaft (8), cooling rolling wheels (6 and 11), wherein, a low temperature slot (12), a compound rolling wheel (30) and a low temperature (4) are in turn arranged between the coating devices (20 and 50). A cooling slot (7) is arranged between the coating device (50) and the coiling shaft (8). The double-side hot melt pressure-sensitive adhesive tape coating device which is used can simultaneously complete coating hot melt pressure-sensitive adhesive liquid and covering anti-sticking paper on double sides of a double-side adhesive tape, and the technology is simple. The production efficiency of the double-side adhesive tape is improved.

Description

Double-side hot melt pressure-sensitive rubber coating device

The utility model relates to the device that the surface evenly is coated with the glue body, refers to that especially a kind of two-sided heat melts the pressure sensitive adhesive tape apparatus for coating.

In packaging industry and daily life, two-sided tape is narrowed by user's green grass or young crops more and more, making with regard to the single face adhesive tape, traditional single face adhesive tape manufacture method is at first to be coated on water based emulsion or solvent borne glue body on the base material equably, then to scribbling the base material heating, drying of glue body, in the heating, drying process, certainly will cause environmental pollution and easily breaking out of fire, also want a large amount of consumes energy simultaneously with harmful inflammable gas evaporation.People adopt heat to melt pressure sensitive adhesive as being coated with the glue body and having adopted die head chamber apparatus for coating thereupon, after melting pressure sensitive adhesive liquid, heat need not dry heating with this kind coating process being coated with, the diffusion that has solved the pernicious gas that preceding kind of coating process cause because of heating, drying and the easy phenomenon of breaking out of fire, but this kind of production two-sided tape method also still must be carried out coated heat to single face respectively with the single face apparatus for coating and be melted pressure sensitive adhesive liquid, treat glue body cooling and be stained be fixed on the base material after, finished the manufacturing of single face adhesive tape, basal surface to another not coated glue body is coated with the glue body and covers separate paper simultaneously again, after treating the cooling of glue body, with it rolling, finish the making of two-sided tape, find out thus with the single face apparatus for coating and make the two-sided tape complex process, operating process repeats, and causes the waste of the manpower and the energy.

The purpose of this utility model is to overcome the shortcoming that above-mentioned apparatus for coating exists, provide a kind of two-sided heat to melt the pressure sensitive adhesive tape apparatus for coating, use this device to be coated with the glue body and to cover separate paper the two-sided of base material successively simultaneously, finish the making of two-sided tape.

The utility model is to realize above-mentioned purpose by following technical solution: in this device, be provided with two identical by on end face have opening, the V-shaped colloid chamber of bottom surface, retaining rubber-surfaced roll wheel and the not tangent single spreading device that maintains a gap of second wheel that the below is respectively arranged with rotating gluing roller and maintains static, also be provided with a pair of compound roller, protect heat tracing groove, a cooling bath and four locating wheels for two.Separate paper guides by one group of single face apparatus for coating coating glue body and through heat tracing groove insulation and from discharging a base material that discharges through guide wheel and is fitted by compound roller, make glue body on the separate paper be coated in the inner surface of base material, by another single face apparatus for coating the outer surface of base material is coated with the glue body again through another heat tracing groove then, base material after the coating and separate paper are through the cooling bath cooling, the double spread glue body of base material and the overwrite procedure of separate paper have so just been finished, move in circles, at last by Scroll with the two-sided tape rolling, complete.

Be coated on simultaneously base material two-sided of adhesive tape successively and finish the covering separate paper because the utility model melts pressure sensitive adhesive liquid with heat, make that the production technology of two-sided tape is simple, avoided the repetition of operating process, improved the efficient of producing two-sided tape.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is an existing die head chamber apparatus for coating schematic perspective view.

Fig. 2 is a transverse plane schematic diagram of the present utility model.

Existing as shown in Figure 1 die head chamber apparatus for coating is to set up the roll bottom in rod 2, colloid chamber 1 of a cylinder in the fluid sealant body cavity 1 that digs arc groove, the groove several sebific ducts that communicate with cavity 3 are housed, heat is melted pressure sensitive adhesive liquid and is pumped into colloid chamber 1 by making the glue pump, and hot melt adhesive liquid is coated on the base material of adhesive tape by the rod 2 that rolls.

As shown in Figure 2, two-sided heat is melted pressure sensitive adhesive coating device and is contained two groups of 6,11, two positioning rollers 2,10 of 7, two pressure rollers of 4,12, one cooling baths of 30, two heat tracing grooves of single face apparatus for coating 20,50, one compound rollers that structure is identical.Single face apparatus for coating 20, by V-shaped colloid chamber 23 of placing the glue body, top opening below with and the V-type both sides place 22 compositions of heating retaining rubber-surfaced roll wheel that 21, one of a rotating heating coating roller maintains static respectively.Gluing roller 21 and stopping roller 22 are not tangent and a gap is arranged, and apparatus for coating 50 and apparatus for coating 20 have same structure.Coating process to two-sided tape is as follows:

The base material 14 of two-sided tape discharges via positioning roller 2 to compound roller 30 by discharging axle 1, meanwhile separate paper 13 discharges through positioning roller 10 by discharging axle 9, cooperate pressure rollers 11 to carry out coated heat by the coating roller 21 of single face apparatus for coating 20 and melt pressure sensitive adhesive liquid, the separate paper 13 of applied glue body is extruded applying when the 31 and 32 tangent places of compound roller 30 simultaneously through an insulation groove 12 and base material 14, make glue body on the separate paper shift inner surface at base material 14, and then pass through another heat tracing groove 4 and cooperate outer surface of 6 pairs of base materials 14 of pressure rollers to be coated with the glue body by another coating roller 51 of organizing single face apparatus for coating 50, base material 14 and separate paper 13 through surfaces externally and internally coating glue body are common through cooling bath 7 coolings, promptly finished the overwrite procedure of the double spread and the separate paper 13 of base material 14, at last by Scroll 8 with the two-sided tape rolling, making finishes.
