Another purpose of the present utility model, also be to provide a kind of embossed surface device of plastic shaped extrudate, so that roll over the position along design and relative folder by recessed (protruding) that change cylinder, press the processing principle of rolling over segmentation simultaneously, can make it be adapted to any difference " abnormal shape " extrudate, thereby reach the effect that extensively is suitable for.

Above-mentioned purpose realizes by following structure, warm that device and back segment have a group or more disc type power facing each other (or non-power) at least impression cylinder constituted mainly comprising a leading portion high temperature, a kind of embossed surface device of plastic shaped extrudate, be divided into respective side along section in the described side of respectively organizing impression cylinder along week edge according to special-shaped extrudate, and be designed to concavo-convex opposite corresponding or straight correspondence along face, and interior rag with comprehensive Boulez, so that special-shaped extrudate is warmed device by leading portion molten soft ductile bed is baked on the top layer, before being imported into this again, in the embossing rolling group that arrange the back, form the Boulez of comprehensive embossing to carry out sectional splint to roll over.

The embossed surface device of above structure is because of considering the woven design effect of plastic shaped extrudate, no matter make on the performance attractive in appearance or all can be on the feel considerably beyond common level and smooth or the straight line line, therefore, overcome the chilly no wonder sense of user fully to often knowing that the plastic cement extrudate is paid, make the treating apparatus of embossed surface have continuous confession, high-effect, the high processing benefit that goes out, low agency cost and low processing charges, and improve its economic benefit and make product reach advanced.

In order at length to illustrate structure of the present utility model and feature, special with a specific embodiment, cooperate simultaneously following shown in accompanying drawing, illustrate as after, wherein draw accompanying drawing and be respectively:

Fig. 1 is a structural upright view of the present utility model.

Fig. 2 is an enforcement three-dimensional view of the present utility model.

Fig. 3 a, 3b and 3c are single group of the present utility model and two groups of impression cylinder effect flow charts and embossing thereof.

Fig. 4 a, 4b and 4c are single group and two groups of pressureization cylinder effect flow charts and the embossings thereof of another embodiment of the utility model.

Fig. 5 is the cutaway view of the AA ' of Fig. 1.

At first see also shown in Fig. 1 and the 2nd, the utility model comprises that mainly a leading portion provides strip processing extrudate 2 when top moment passes through, through can produce " superficial layer " be subjected to the soft one-tenth of hot melt only have moldable surface can high temperature warm device 3 and back segment according to extrudate 2, the cross section require embossing week edge, and many groups of the segmental machining of the doing design plate-like rolling groups that are provided with of row and front and back relatively in twos, wherein, the segment design principle on all edges of described embossing is, with week of extrudate 2 along the embossed areas that is divided into both sides " all overlaids " every, A1 as shown in Figure 5, A2, A3 and A4 four districts, again respectively with each (certainly) power (or dead axle of non-power) plate-

like cylinder

41,42,43 and 44, make adapt to respectively each section arc along and constitute the cylinder side and have the recessed of style rag Boulez along 411,421,431 and 441, and with location facing each other setting, make and form each tandem through port, and it is soft and by (411 and 431 1 groups on one group recessed edge in twos in extrudate 2 through surface moment baking, 421 and 441 1 groups) time, its surface is pushed by the rag in the recessed edge, the branch preface is rolled spreading and is made line, and after the pressure of each section is rolled over all enforcement, can finish comprehensive woven design of extrudate; In addition, each close cylinder side is along different embossing width must constitute or have the overlapping extrusion in both sides (embossing) in front and back, and it is with being intended to eliminate " lapping defect " that line is rolled in segmentation; Then will be illustrated among what Fig. 3 for one-tenth line process of the present utility model.
