Problems solved by technology
The disadvantage of the above-mentioned production equipment is: when the lower armor layer 25, the material 23 and the upper armor layer 21 are rolled together by the upper and lower molding rollers 22 and 26, the materials are easy to enter and stick to the upper armor layer 21 The edge parts on both sides of the upper and lower armor layers—that is, the part that is bonded to the flanging of the lower armor layer 25 during edge wrapping, resulting in weak bonding between the upper and lower armor layers 21 and 25, thus affecting the quality of the edge wrapping

Embodiment Construction
[0014] As shown in Fig. 1, Fig. 2 and Fig. 3, the specific structure of the isolating device in the decorative plate production equipment according to the present invention is: above the side of the feeding direction of the upper forming pressure roller 22, two smooth Isolating strips 12, in actual production, two isolating strips 12 can be suspended on a crossbar 11 arranged in the frame 1, and the distance between the two isolating strips 12 is the same as the width of the decorative plate 28 produced. Correspondingly, the lower ends of the two isolation strips 12 can be respectively arranged on the insides of the edge sticking parts on both sides of the upper armor layer 21 to be hemmed. Moreover, in this embodiment, as shown in FIG. 5 and FIG. 6 , the width of the isolation strip 12 is consistent with the width of the flange 251 of the lower armor layer 25 , and its thickness is consistent with the thickness of the lower armor layer 25 .

The invention relates to a separator which can avoid adhering material on two side edges of upper protective layer. Wherein, it comprises two smooth separating bands inside the frame; the separating band is at the material feeding direction of upper compressing roller; one end of separating band is at the inner side of said edge; when producing, the lower side of separating bands are at the inner side of upper protective layer and at two side edge of upper protective layer; therefore, when the upper and lower shaping compressing rollers roll, the edges of middle material and upper protective layer will not contact, to avoid adhering material on the upper protective layer.
Description
technical field [0001] The invention relates to a production equipment of a fireproof decorative plate with a protective surface layer, in particular to an isolation device in the production equipment. Background technique [0002] In the building decoration industry, all kinds of plates made of inorganic substances as the main raw materials have been more and more widely used. It has many advantages such as flame retardancy and saving natural resources. Among them, the gypsum board made of gypsum as the main raw material is used in a large amount. At present, a decorative board made of magnesium oxychloride, magnesium oxysulfate, and modified gypsum as the main raw material is also being used more and more widely. The structure of the above-mentioned building decoration boards is similar, and usually includes at least one intermediate material layer and the protective surface layer on both sides. The intermediate material layer is made of gypsum, or magnesium oxychloride, m...
