Staircase anti-biting bar and forming technology thereof

Abstract

The invention discloses an anti-clip strip for an escalator and a moulding technique thereof. The anti-clip strip comprises a base and an anti-clip component which are arranged on a skirt panel of the escalator, wherein, the anti-clip component is provided with an anti-clip fixing strip which can be tabled with the upper opening of the base and an anti-clip blocking strip which protrudes outwards and extends along one edge of the anti-clip fixing strip; at least one metal green plate which is capable of controlling the contraction of the anti-clip strip component passes through the inner part of the anti-clip fixing strip. The moulding technique comprises steps of mixing granulation, plastic modification, base moulding and the extrusion molding forming, the component and the products finishing of the anti-clip strip component. Both the base and the anti-clip strip component of the invention adopt the moulding technique of plastic extrusion and have low production cost and convenient production; the metal green plate is embedded into the anti-clip fixed strip, thereby further controlling the contraction distortion of the anti-clip strip component in the extrusion process and having higher moulding quality of the extruded anti-clip strip component; both the base and the anti-clip strip component adopt flexible plastic materials, thereby having better bending property and being convenient for the operation of a dismantlement process.

Description

technical field [0001] The invention relates to the technical field of escalator protection, in particular to an escalator anti-pinch strip and a forming process thereof. Background technique [0002] At present, the competition in the elevator and escalator market is increasingly fierce, and the products are constantly updated. On the premise of ensuring quality, major elevator companies intensively simplified and continuously replaced and improved the sealing strips used in elevators; from the perspective of their functions, the anti-pinch strips of escalators are nothing more than anti-pinch, anti-collision, dust-shielding, and decorative functions; the original The anti-trap device is generally assembled with aluminum alloy or hard plastic extruded parts and brushes, which has high processing costs, and the brush structure has the disadvantages of dust accumulation and difficulty in cleaning, and its overall appearance is not beautiful. [0003] Briefly describe the saf...

Problems solved by technology

[0005] 2. Although the anti-trap device is not mentioned in the A17.1 specification of the United States, there are safety requirements in this regard in some state regulations

The structure and the apron board adopt the connection method of bolts and nuts. This connection method is likely to cause the entire anti-pinch bar and the apron board to be uneven, and some clip bars are easy to arch in the middle, forming the entire uneven phenomenon; repairs cause difficulties
