Material sucking device and filling equipment

Abstract

The invention discloses a material sucking device and filling equipment, and belongs to the technical field of optical cable manufacturing. The material sucking device is used for sucking a material in a packaging bag into a material filling device and comprises a material sucking head and a balancing weight, wherein the material sucking head is of a hollow structure with the side wall being provided with through holes, is arranged in the material in the packaging bag in a buried mode and communicates with the material filling device through a material sucking pipe, and the balancing weight and the material sucking head are connected through a first rope. The filling equipment comprises the material filling device and the material sucking device. The material sucking head is arranged in the material in the buried mode and balanced through the balancing weight, thus the material sucking head can automatically sink along with continuous reducing of the material in the packaging bag to ensure continuous material supplying to the material filling device, and the phenomenon of material discontinuing is avoided.

Description

technical field [0001] The invention relates to the technical field of optical cable manufacturing, in particular to a material suction device and filling equipment. Background technique [0002] For the central bundle tube optical cable, the longitudinal wrapping structure of water-blocking powder and corrugated steel strip can not only reduce the manufacturing cost of the cable, but also significantly improve the water-blocking effect. When water seeps in, the water-blocking powder can expand to the original Ten times to dozens of times, it blocks the water seepage channel, stops the further diffusion and extension of water or water vapor, and effectively protects the optical cable in the center. [0003] The existing process method manually adds the water blocking powder into the funnel, and then injects the water blocking powder into the corrugated steel strip through the funnel, so that the water blocking powder is tightly stuck on the outer surface of the bundle tube a...

Problems solved by technology

[0003] The existing process method manually adds the water blocking powder into the funnel, and then injects the water blocking powder into the corrugated steel strip through the funnel, so that the water blocking powder is tightly stuck on the outer surface of the bundle tube and the inner surface of the corrugated steel strip; Material breakage, material shortage or insufficient material supply lead to non-blocking water powder or discontinuous distribution of water-blocking powder in the corrugated steel strip, which affects the water-blocking effect of the product. At the same time, there is a micro gap between the bundle tube and the corrugated steel strip. There is relative sliding between the tube and the corrugated steel strip, which affects the attenuation and mechanical properties of the optical cable
