Product introduction

Hard quick-rolling doors are suitable for external doors, internal doors, access doors and various frequently separated areas with pressure difference, wind resistance and speed requirements in the factory building; The specific departments are logistics area, assembly workshop, painting workshop, body workshop, stamping workshop, engine workshop, etc. It has high temperature insulation performance, sealing, heat insulation, strong anti-theft, long service life, intelligent control, expert/electric opening and closing functions, and good sound insulation effect.

Advantages of main components

Power system:

   SEW motor and frequency conversion control system are adopted, and the power is 0.75~3kw.

   Adopt servo system motor and servo closed-loop control system with power of 0.75kw~2.2kw.

Control system:

Adopt high-performance upgrade control box, which has the characteristics of high performance, high reliability, high stability and high precision positioning; At the same time, it also has the functions of soft start and slow stop to ensure the smooth operation of the door body and increase the service life.

Orbit:

Spiral track, synchronous lifting, non-reel winding, easier to balance, door panels are quickly rolled up along the spiral track under the driving of lifting, and there is zero contact between door panels; The two ends of the door panel are equipped with polymer pulleys, which play an accurate guiding role in the side rails. When the door panels are rolled up, they are not in contact with each other, so the life of sliding friction is longer and the door panels can be better protected. The two ends of the transmission shaft at the top of the door are anti-wear spiral storage tracks. After the door panels are rolled on the top, there is no contact or friction between the door panels, and the door panels will never wear.

High strength spring balance system;：

Use tension spring to balance the weight of the door. The strong lifting belt connects the door panel with the high-strength tension spring group to prevent the door panel from falling suddenly in case of failure. In addition, in the process of door opening, the spring fixed on the ground and the connected hidden lifting belt also provide support for the driver, and the door can still be opened safely when the power is cut off.

Door body:

The door panel is painted with aluminum coil on both sides, filled with polyurethane insulation material, with a standard height of 195mm, and the connection is treated with broken bridge, with a thickness of 40 mm.

Window:

Adopt transparent windows made of acrylic material on both sides, which is not worn and aging.

Sealing performance:

Sealing strips are arranged around the door body to ensure the tightness of the door body.

Safety performance:

    Infrared security: each door is equipped with a set of photoelectric protection system to prevent the rolling door from falling and touching pedestrians or vehicles.

    Airbag: Each door is equipped with a bottom airbag, which can make the door run in the opposite direction when encountering obstacles in the process of rolling down, so as to avoid damage.

Light curtain (optional):

Powerful safety detection function, wide coverage and more comprehensive protection.

Opening and closing speed:

    The opening speed is not less than 1.2m/s. It can be adjusted through program settings.
