Description

Technical area

The present utility model relates to a roller door, in particular an automatic safety roller door.

State of the art

As an automatic safety roller door is often referred to a driven by a gear and mounted in a gutter door, which consists of several parallel connected door leaves, which rises along the winding shaft up there and goes down. Such security doors are often used in shops, garages, department stores, hospitals, factories, factories and other public places or in private households. Because of the huge door opening, the automatic security roller door can be conveniently opened and closed in places where the general doors are not simply placed or mounted on the floor. When used as a door for garage, fire door for department stores or door for aircraft hangar climbing, holding or sinking of the automatic roller door can be realized by a control unit.

Today, no manual operation for the roller doors on the market is required, but there is still much doubt about their fire-proof property despite the smooth operation. Especially at the application sites such as in warehouses such roller doors without fire resistance in fire accidents can lead to major damage. Even with current use loud noises between roller blind and gutter are not ignorable.

Content of the utility model

The object of the present utility model is to provide an automatic safety roller door to solve the present problems.

For this purpose, technical solution of the present utility model is as follows: automatic safety roller door, comprising a winding shaft, which is arranged in a fireproof ceiling, wherein the fireproof ceiling is still equipped with a gear, also comprising a roller blind, which coincides with the length of the winding shaft , wherein a roller is arranged respectively on the left and right sides of the roller blind, wherein a groove is arranged respectively at the left and right end of the floor of the fireproof ceiling, wherein a high polymer composite layer is disposed respectively in each groove, which in a U-shape wherein the rollers slidably mate with the high polymer composite layer, the roller blind comprising a first fire protective layer and a second fire protective layer, wherein a soundproofing layer is interposed between the first fire protective layer and the second fire protective layer, comprising one more Power module and a controller, wherein the power module is connected by lines and the control unit to the transmission.

Furthermore, the first fire protection layer and the second fire protection layer consist of inorganic composite fiber.

Furthermore, the soundproofing layer consists of rigid polyurethane foam.

Furthermore, an anti-oxidation layer is placed on the outer wall of the roller blind.

Compared with the prior art, the advantages of the present utility model are in the fire-proof properties of the automatic roller door except its expediency. In this case, the first fire protection layer and the second fire protection layer for effective fire protection and thermal insulation are still arranged to ensure safety. In addition, the soundproofing layer is still arranged for effective noise reduction. The rollers and high polymer composite layer are also arranged, thereby the friction can be reduced by the rollers, so do not cause so loud noises when rolling up the roller blind. Because of the use of the high polymer compound layer, with which the rollers fit together smoothly, the noise can be further reduced.

Detailed embodiment

Connected to the following drawing, the preferred embodiment of the present utility model can be explained.

Embodiment 1: with respect to 1 . 2 and 3 shows an automatic safety roller door, comprising a winding shaft 1 which are in a fireproof ceiling 7 is arranged, the fireproof ceiling 7 still with a gearbox 2 equipped, including a roller blind 5 , which with the length of the winding shaft 1 coincides with a roller 6 each on the left and right side of the roller blind 5 is arranged, with a channel 4 respectively at the left and right end of the floor of the fireproof ceiling 7 is arranged, wherein a high polymer composite layer 401 each in each gutter 4 is arranged, which is configured in a U-shape, wherein the rollers 6 with the high polymer composite layer 401 Sliding match, with the roller blind 5 a first fire protection layer 501 and a second fire protection layer 503 includes, wherein still a soundproofing layer 502 between the first fire protection layer 501 and the second fire protection layer 503 is arranged, still comprising a power supply module and a control unit 3 , wherein the power supply module through lines and the control unit 3 connected to the transmission 2. The power supply module is plugged into the fireproof cover 7 and drives the rotation of the winding shaft 1 through the transmission 2 , so the roller blind 5 ascend and go down. During the ascent is the winding shaft 1 from the roller blind 5 rolled up and the roller blind slips when sinking 5 along the inside of the gutter 4 down. By controlling the control device, the curtain can rise, hold and go down. The high polymer composite layer 401 is made of polymer composites, which has the advantages such as high strength, light weight, temperature resistance, corrosion resistance, thermal insulation, electrical insulation, this allows the rollers 6 smoothly with the high polymer composite layer 401 so that the noise can be reduced properly. The first fire protection layer 501 , the soundproofing layer 502 and the second fire protection layer 503 are arranged to realize fire protection, thermal insulation and noise insulation.

In the present embodiment, preferably, the first fire protection layer 501 and the second fire protection layer 503 of inorganic composite fiber, which has good properties such as temperature resistance, high compressive strength, good elastic modulus and strong oxidation resistance.

In the present embodiment, preferably, the soundproofing layer 502 made of rigid polyurethane foam, which has the properties such as effective insulation and soundproofing, waterproofness and moisture resistance after solidification.

In the present embodiment, it is preferable to have an antioxidant layer on the outer wall of the roller blind 5 applied to the life of the roller blind 5 to extend and to avoid corrosion.
