Description

Thick tectorial membrane roller of accuse of pitch coiled material

Technical Field

The utility model relates to the field of asphalt waterproof coiled material production equipment, in particular to a thickness-control film-coating roller of an asphalt coiled material.

Background

In the production process of the existing asphalt waterproof coiled material, a film coating process is a common coiled material packaging process and is usually arranged before cooling and forming. Because the thickness control of current pitch waterproofing membrane generally sets up before the tectorial membrane, what the tectorial membrane structure on most pitch waterproofing membrane production line adopted is passive form motion, and tectorial membrane roller self need not loading power promptly, only relies on the friction drive its rotation when the coiled material passes through. Therefore, the existing laminating roller has low requirement on the strength of the structure, and the rotating shaft of the laminating roller usually adopts two short shafts which are respectively arranged at two ends of the laminating roller, so that once the laminating roller needs to apply pressure to control the thickness, the rotating shaft is easy to have the problem of stress concentration, is easy to deform after being used for a long time, and cannot adapt to the requirement of accurate thickness control.

The traditional asphalt coiled material can be coated without heat dissipation after being coated, but with the development of technology, in order to meet the requirements of more performances, a new asphalt material and more films are introduced in the production of the asphalt waterproof coiled material, and with various combinations of the new asphalt material and the new films, when the traditional process is applied to some asphalt materials with higher coating temperature requirements and films with relatively lower coating temperature requirements, the coating structure which is lack of cooling in the existing production process cannot be applied; on the other hand, as the thickness of the laminating roller needs to be controlled, the rotating speed is slowed down, and the heat transferred to the laminating roller by the asphalt coiled material is increased. The prior art lacks a laminating roller which can be simultaneously suitable for controlling thickness and temperature so as to meet the requirement of new production.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome at least one defect (deficiency) of the prior art and provides a thickness-control laminating roller for asphalt coiled materials, which is used for solving the problem that the existing laminating roller cannot be applied to thickness control and temperature control.

The technical scheme adopted by the utility model is that the thickness-control laminating roller for the asphalt coiled material comprises: the cooling device comprises a roller, a main shaft and a rotary joint, wherein one end of the roller is provided with a closed plate, the other end of the roller is an open surface, and a cooling cavity is arranged inside the roller; the main shaft penetrates through the cooling cavity and is connected with the sealing plate; the rotary joint is arranged on the sealing plate and connected with the main shaft; one end of the cooling cavity is communicated with the outside of the roller through the main shaft and the rotary joint, and the other end of the cooling cavity is communicated with the outside of the roller through the open surface.
