The present invention relates to a rolling device for producing insulation pipes, and in particular, when the glass fiber mat is wound in multiple layers, the binder is automatically immersed in the contact surface of the glass fiber mat, so that the binder process and the winding process of the insulation pipe are easily made. It relates to a rolling device for manufacturing.

In general, pipes such as cooling and heating facilities of power generation and petrochemical plants, cooling and heating facilities of industrial equipment, cooling and heating facilities of various manufacturing equipment, and heating and cooling facilities of air conditioning equipment are used for insulating materials of various sizes and materials. Insulation materials (hereinafter referred to as 'insulation pipes') are installed to block heat exchange with the outside through the pipe to achieve energy savings and cost reduction.

In recent years, in order to reduce manpower and improve productivity, the insulation pipes are made through automation lines when installing (installing) these pipes. The insulation pipes can be automatically inserted into the pipes. Standardization is required.

Accordingly, a method for automatically manufacturing the insulation pipe as described above has been published, and the insulation pipe production method includes a supply step of supplying raw materials, that is, glass fibers in a mat form, and a glass fiber mat supplied in the supply step. And a binder spraying step of spraying a binder on the surface, a winding step of winding up a glass fiber mat sprayed with a binder, and a drying step of drying the wound glass fiber mat.

The insulation pipe manufactured by the insulation pipe manufacturing step as described above is formed by winding a glass fiber mat in multiple layers, and each glass fiber mat is bonded to each other by a binder applied to the surface thereof to produce one insulation pipe. .

However, since the binder spraying step of applying the binder to bond the glass fiber mat is made by spraying the binder on the glass fiber mat, the amount of binder applied on the surface of the glass fiber mat cannot be controlled so that the binder is sprayed excessively. As the shape of the fiber mat is deformed or the consumption of the binder is increased, the production cost is increased, and the injection amount of the binder is small, so that the glass fiber mat is not properly adhered and thus loses the adhesive force, and thus, each fiber mat layer is separated and peeled off. Insulation pipes manufactured as described above have a problem that heat is leaked when they are installed on cooling and heating pipes due to loss of insulation function, resulting in waste of energy and risk of accidents. There was a problem that occurred.
