Abstract

The utility model discloses an impregnated canvas for a heavy-duty conveyor belt. Warp and weft surfaces of the canvas are coated with impregnated layers, the canvas adopts a 'two up and two down' broken-twill-weave structure, warps of the canvas adopt industrial polyester filaments, and wefts of the canvas adopt nylon 66 industrial filaments. Compared with a regular plain-weave structure, the utility model has the advantages as follows: since the interweaving times of warps and wefts are reduced, the strength loss of warps is little, the wrap-direction breaking strength is greatly improved, the strength keeping rate is over 90 percent after fibers are weaved into a fabric, warp-direction curvature is great, dry weight for each square meter is light, and the canvas is bonded with rubber perfectly; and the heavy-duty conveyor belt made of the canvas as the belt core is characterized by high breaking strength, good fatigue durability, stable running, and low possibility of crease generation and rubber layer shedding.

Description

The heavy-duty conveyor belt dipped canvas

Technical field

The utility model relates to a kind of canvas in the technical field of textile chemical engineering, specifically, is a kind of dipped canvas that is used as the belt carcass of heavy-duty conveyor belt.

Background technology

At present, Chang Gui heavy-duty conveyor belt mainly adopts plain weave structure with dipped canvas.The defective that adopts plain weave structure to exist is: because the interleaving degress of warp and parallel is many, thereby the strength loss of warp is big, fracture strength is low, the canvas that is woven into is harder, and warp-wise curvature is little, and every square metre of dry weight is big, bonding firm inadequately with rubber, the conveyer belt of finally making easily plays the pleat trace, and behind the conveyer belt long-play, rubber layer easily comes off.

The utility model content

Technical problem to be solved in the utility model is: at the defective of above-mentioned prior art, provide a kind of heavy-duty conveyor belt dipped canvas, fracture strength is low, warp-wise curvature is little, every square metre of problem that dry weight is big to solve.

For solving the problems of the technologies described above, the technical solution of the utility model is: the heavy-duty conveyor belt dipped canvas, and the warp of described canvas and the surface of parallel all are coated with rubber shoe latex layer, and described canvas adopts twice disconnected twill-weave structures on two; The warp of described canvas adopts polyester industrial filament yarn; Described woof threads adopts nylon 66 industrial filaments.

As preferably stating technical scheme, the warp-wise density of described canvas is 100～190/cm; The latitudinal density of described canvas is 30～65/cm.

As preferably stating technical scheme, the twisting twist of the warp of described canvas and parallel is 6～15 sth. made by twisting/10cm.

Owing to adopted technique scheme, compared with prior art, the beneficial effects of the utility model are: adopt twice disconnected twill-weave structures on two, compare with the plain weave structure of routine, because it is many to have reduced the interleaving degress of cellular organization's middle longitude and parallel, the warp strength loss is little, the warp-wise fracture strength significantly improves, and makes fiber be made into strength retention behind the fabric more than 90%, and warp-wise curvature is big, every square metre of dry weight is little, and is good with the cohesiveness of rubber; The heavy-duty conveyor belt of finally making as belt carcass with this canvas has the advantages that fracture strength height, fatigue durability are good, operate steadily, be difficult for pleat trace, rubber layer difficult drop-off.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

Among the figure: the 1-warp; The 2-parallel.

The specific embodiment

Shown in Fig. 1, Fig. 2 and Fig. 3 are common, the heavy-duty conveyor belt dipped canvas, the warp 1 of described canvas and the surface of parallel 2 all are coated with rubber shoe latex layer, twice disconnected twill-weave structures in the described canvas employing two, the crow leg structure that this structure promptly is commonly called as; The warp 1 of described canvas adopts polyester industrial filament yarn; Described woof threads 2 adopts nylon 66 industrial filaments.Wherein, the warp-wise density of described canvas is 100～190/cm, and the latitudinal density of described canvas is 30～65/cm; The warp 1 of described canvas and the twisting twist of parallel 2 are 6～15 sth. made by twisting/10cm, and the sth. made by twisting of described warp 1 and parallel 2 is to adopting Z to twist with the fingers or the S sth. made by twisting.

With the heavy-duty conveyor belt of twice disconnected twill-weave structures on two with the EP-400 dipped canvas as embodiment draw materials and the twisted weave structure sees the following form:

Claims

1. heavy-duty conveyor belt dipped canvas, the warp of described canvas and the surface of parallel all are coated with rubber shoe latex layer, it is characterized in that: described canvas adopts twice disconnected twill-weave structures on two; The warp of described canvas adopts polyester industrial filament yarn; Described woof threads adopts nylon 66 industrial filaments.

2. heavy-duty conveyor belt dipped canvas as claimed in claim 1 is characterized in that: the warp-wise density of described canvas is 100～190/cm; The latitudinal density of described canvas is 30～65/cm.
