Abstract

The utility model discloses an anti-adhesion foil roller used in an automatic hot stamping die-cutting machine, wherein, the external surface of the anti-adhesion foil roller is coated with a Teflon coating. The anti-adhesion foil roller solves the problem that the high temperature generated by a heater and the heat generated due to the friction between a clamping roller and a drum during a high-speed hot stamping cause an adhesion to the aluminum foils under hot stamping to affect the hot stamping speed and accuracy severely. The foil roller is coated with a Teflon coating and the Teflon coating is notably characterized by anti-adhesion, abrasion resistance and high temperature resistance, therefore, the hot stamping quality problem due to atheroma is overcome obviously, the operation is convenient and the hot stamping speed and accuracy are accelerated.

Description

A kind of antiseized paper tinsel roller of crossing

Technical field

The utility model relates to automatic hot stamping die cutting machine field, relates in particular to the paper tinsel roller excessively that is used for automatic hot stamping die cutting machine.

Technical background

See also Fig. 1, for automatic hot stamping die cutting machine vertically send the paper tinsel stamping systems to move towards schematic diagram, after sending paper tinsel roller 1 to rotate, with stamping systems 2 after put paper tinsel dish 3 and pull out, cross paper tinsel roller 4, second through first and cross paper tinsel roller 5, enter the hot stamping unit of forming by heating plate 6, cellular board 7, thermoprint plate 8 and printing plate 9 etc., after the pattern transfer of stamping systems 10 is to the printing paper, by receiving the rotation of paper tinsel roller, the stamping systems that will give up is crossed paper tinsel roller the 11, the 4th through the 3rd and is crossed that paper tinsel roller the 12, the 5th is crossed paper tinsel roller 13 and some transition rollers 14 are delivered to useless paper tinsel case.As can be seen from Figure 1, because second cross paper tinsel roller the 5, the 3rd and cross paper tinsel roller the 11, the 4th to cross paper tinsel roller 12 nearer apart from hot stamping unit, heating plate 6 can heat the outer surface that these cross the paper tinsel roller equally, and through measuring, the outer surface heat of crossing the paper tinsel roller tends to reach 850-1000C.In addition, when stamping systems 10 nuzzles up at a high speed, also can produce very high heat from the outer surface of crossing the paper tinsel roller.

Please Figure 2 shows that the structural representation of stamping systems 10: the structure of stamping systems 10 is complicated, generally is made up of PE film 101, peel ply 102, transfer printing layer (dye layer 103 and aluminium coated 104) and adhesive-layer 105.During thermoprint, at printing plate and stamping systems in 10 contacted several milliseconds of times, peel ply 102 oxidations, adhesive-layer 105 fusings, after the pressurization, transfer printing layer with bonding by printing paper, is realized the transfer printing of stamping systems by the effect of adhesive-layer 105.Because stamping systems 10 often exists the too quality problems of pine of peel ply 102, the bronze of thermoprint after stain chromatograph 103 occurs falling from (also claiming firkin) phenomenon easily, in a single day these bronzes combine through a small amount of glue that first to the 5th very high mistake paper tinsel roller of surface temperatures was overflowed by adhesive-layer 105 in 4,5,11,12,13 o'clock with stamping systems 10, can form as shown in Figure 3 " sebaceous cyst " shape.These " sebaceous cysts " the lighter can make the pattern edge of thermoprint on printing paper adhere to some powder, influences the thermoprint quality; Heavy person's stamping systems 10 can be broken because of colloid " sebaceous cyst " in sending the paper tinsel process.Traditional paper tinsel roller surface general employing chromium plating of crossing is handled, and the generation of colloid " sebaceous cyst " can't be avoided in this surface.In case formation " sebaceous cyst " just must be stopped, carry out cleaning to crossing paper tinsel roller surface in the thermoprint process, owing to the space of hot stamping unit is often very narrow and small, therefore cleaning is got up time-consuming bothersome again.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art and a kind of antiseized paper tinsel roller of crossing is provided, it has solved because of the heat of friction generation between the high heat of the generation of heater in the high speed thermoprint process and pinch roller and the roller makes by the aluminium foil of thermoprint and has sticked together, and has a strong impact on the problem of thermoprint speed and precision.

The technical scheme that realizes above-mentioned purpose is: a kind of antiseized paper tinsel roller of crossing, be used for automatic hot stamping die cutting machine, and wherein, this antiseized outer surface of crossing the paper tinsel roller scribbles teflon coatings.

The above-mentioned antiseized paper tinsel roller of crossing, wherein, described teflon coatings is at least one deck.

The beneficial effects of the utility model are: the utility model has been coated with teflon coatings to crossing paper tinsel roller surface, because a distinguishing feature of teflon coatings is antiseized, second characteristic is wear-resisting, the 3rd characteristics are high temperature resistant, and its price equates with the chromium plating processing, after the method that is coated with teflon coatings has been adopted on paper tinsel roller surface excessively, has obviously overcome the thermoprint quality problems that produce because of " sebaceous cyst ", easy to operate, accelerated thermoprint speed and precision.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

See also Fig. 4, there is shown a kind of antiseized paper tinsel roller 1 ' of crossing of the present utility model, be used for automatic hot stamping die cutting machine, this antiseized outer surface of crossing paper tinsel roller 1 ' scribbles teflon coatings 11 ', and this teflon coatings 11 ' is at least one deck.A distinguishing feature of teflon coatings 11 ' is antiseized, and second characteristic is wear-resisting, and the 3rd characteristics are high temperature resistant, have overcome the thermoprint quality problems that produce because of " sebaceous cyst ".

Though through the utility model is described in conjunction with specific embodiments, for the skilled personage in present technique field, according to substituting of making of narration above, revise with variation will be conspicuous.Therefore, such substituting, in the spirit and scope that modifications and variations fall into attached claim the time, should be included in the utility model.

Claims

1. the antiseized paper tinsel roller of crossing is used for automatic hot stamping die cutting machine, it is characterized in that, this antiseized outer surface of crossing the paper tinsel roller scribbles teflon coatings.
