Three-shuttle circular weaving machine for high pressure resistant large-caliber hose fabric

Abstract

The invention discloses a three-shuttle circular weaving machine for a high pressure resistant large-caliber hose fabric. The three-shuttle circular weaving machine is characterized by comprising a machine body supporting device, a transmission device, a weaving device and a motor, wherein the transmission device and the weaving device are fixed on the machine body supporting device; the machine body supporting device comprises a rack, a large base plate, a central seat, seat rings, pressure ring sleeves and cylinder port seats; the large base plate is arranged on the rack; the central seat is arranged on the large base seat; the pressure ring sleeves are arranged on two sides of the upper end of the central seat; cylinder port seats are arranged on the pressure ring sleeve; and the seat rings are arranged on two sides of the cylinder port seats. The three-shuttle circular weaving machine has the advantages that the machine is high in reliability, simple in structure and convenient to maintain, more warp positions are provided, the weavable density is high, a large-caliber hose strip with a larger size can be produced, a traction device is fixed on the rack, the height of the central seats is shortened, the traction distance is increased effectively, the traction uniformity is kept, the machine height is controlled at the same time, the operation stability is improved, and the machine is easy to assemble and maintain and simple in structure.

Description

technical field [0001] The invention relates to a circular loom, in particular to a three-shuttle circular loom for high-pressure-resistant large-diameter hose fabrics. Background technique [0002] With the rapid development of the petrochemical industry, etc., it provides a solid technical foundation and material foundation for the research and development of fire protection and water delivery hoses. Require. The new national standard: "Fire Hose Performance Requirements and Test Methods GB6246-2001" puts forward the requirements for fire hoses with diameters above Φ80mm, including inner diameters of Φ100mm, Φ125mm, Φ150mm, Φ200mm, Φ250mm, and Φ300m. However, hoses with a diameter of more than 250mm cannot be braided with circular looms such as our company’s model FH250A / B and Mandel HM604. Even if weaving 200-250mm, it is necessary to add special accessories to modify the machine and weave. Inconvenient; and the air palm circular loom that can weave large-caliber hose f...

Problems solved by technology

However, hoses with a diameter of more than 250mm cannot be braided with circular looms such as our company’s model FH250A / B and Mandel HM604. Even if weaving 200-250mm, it is necessary to add special accessories to modify the machine and weave. Inconvenient; and the air palm circular loom that can weave large-diameter hose fabrics has the disadvantages of complex structure, high failure rate, difficult debugging, unstable weft density and insufficient weaving layer
