Abstract

The utility model discloses a composite organization structure gumming canvas for a conveyer belt, wherein gumming layers are coated on the surfaces of a longitude line and a latitude line of a canvas, the canvas adopts a straight longitude line and straight latitude line composite structure, the longitude line comprises a main longitude line and a knitting longitude line which are arranged at interval, the latitude line is divided into two layers, the two layers of latitude lines are respectively arranged on two sides of the major longitude lines and are opposite in twos, the knitting longitude line is crossed with the latitude line, and the main longitude line is not crossed with the latitude line. The conveyer belt made of the canvas has the advantages of strong fracture intensity, excellent fatigue, stable operation and long service span, and can not delaminate after long-term running.

Description

Used for conveyer belt complex tissue structure dipped canvas

Technical field

The utility model relates to a kind of canvas in the technical field of textile chemical engineering, specifically, relates to a kind of complex tissue structure dipped canvas that is used as the belt carcass of conveyer belt.

Background technology

Because plain weave or twill-weave structure are weaved simply, traditional used for conveyer belt dipped canvas adopts plain weave or twill-weave structure usually.But the defective of its existence is: because warp and parallel are through repeatedly interweaving, warp loss of strength after interweaving is big, the canvas strength retention that is woven into is low, generally to adopt the multilayer canvas to make the belt carcass of conveyer belt, conveyer belt easily plays the pleat trace, after moving for a long time, easily be elongated, and between each layer canvas slippage take place easily.

The utility model content

Technical problem to be solved in the utility model is: provide a kind of used for conveyer belt complex tissue structure dipped canvas at above-mentioned defective, to solve the easily pleat trace that conveyer belt exists in the prior art, easily be elongated behind the long-play, the problem of slippage easily takes place between each layer canvas.

For solving the problems of the technologies described above, the technical solution of the utility model is: used for conveyer belt complex tissue structure 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 straight through straight latitude complex tissue structure; Described warp comprises main warp line and the braiding warp that is provided with at interval, and described parallel divides two-layer, and described two-layer parallel lays respectively at the both sides of main warp line and relative in twos, and described braiding warp and described parallel interweave, and described main warp line and described parallel do not interweave; It is the polyester thread of 22000dtex～44000dtex that described main warp line adopts line density; It is polyamide fibre 66 industrial filaments of 930dtex～1870dtex that described braiding warp adopts line density; It is polyamide fibre 66 industrial filaments of 6000dtex～12000dtex that described parallel adopts line density.

As optimized technical scheme, the density of described canvas main warp line is 35～60/10cm; The density of described canvas braiding warp is 70～120/10cm; The density of described canvas parallel is 20～50/10cm.

As optimized technical scheme, the twist of the main warp line of described canvas is 3～8 sth. made by twisting/10cm; The twist of the braiding warp of described canvas is 6～12 sth. made by twisting/10cm; The twist of described woof threads is 5～10 sth. made by twisting/10cm.

Owing to adopted technique scheme, compared with prior art, the beneficial effects of the utility model are: because described canvas adopts straight complex tissue structure through straight latitude, described parallel divides two-layer and lays respectively at the both sides of main warp line and relative in twos, the main warp line and the parallel of described canvas do not interweave, have only braiding warp and parallel to interweave, the main warp line does not have loss of strength, the canvas warp-wise ultimate strength conservation rate height that is woven into, be difficult for stretcher strain, good with the bond properties of rubber, needn't adopt the belt carcass of multilayer canvas as conveyer belt; The conveyer belt made from the canvas of this structure have fracture strength height, fatigue durability good, operate steadily, can delamination behind the long-play thereby the advantage of long service life yet.

Description of drawings

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

Fig. 2 is the structure front view of the utility model embodiment;

Among the figure: 1-main warp line; 2-weaves warp; The 3-parallel; A, B, C and D represent to be positioned at one group of parallel with on one deck respectively; A1, B1, C1 and D1 represent to be positioned at one group of parallel on another layer respectively.

The specific embodiment

As shown in Figure 1, used for conveyer belt complex tissue structure dipped canvas, the surface of the warp of described canvas and parallel 3 all is coated with rubber shoe latex layer, and described canvas adopts straight through straight latitude complex tissue structure; Described warp comprises main warp line 1 and the braiding warp 2 that is provided with at interval, described parallel 3 minutes is two-layer, it is also relative in twos that described two-layer parallel 3 lays respectively at the both sides of main warp line 1, and described braiding warp 2 interweaves with described parallel 3, and described main warp line 1 does not interweave with described parallel 3; It is the polyester thread of 22000dtex～44000dtex that described main warp line 1 adopts line density; It is polyamide fibre 66 industrial filaments of 930dtex～1870dtex that described braiding warp 2 adopts line density; It is polyamide fibre 66 industrial filaments of 6000dtex～12000dtex that described parallel 3 adopts line density.Wherein, the density of described canvas main warp line 1 is 35～60/10cm; The density of described canvas braiding warp 2 is 70～120/10cm; The density of described canvas parallel 3 is 20～50/10cm.Wherein, the twist of the main warp line 1 of described canvas is 3～8 sth. made by twisting/10cm; The twist of the braiding warp 2 of described canvas is 6～12 sth. made by twisting/10cm; The twist of described woof threads 3 is 5～10 sth. made by twisting/10cm.

In order further to observe institutional framework of the present utility model, the physical location of one deck parallel is done the skew of globality, thereby obtain front view as shown in Figure 2, wherein, A, B, C and D represent to be positioned at one group of parallel with on one deck respectively; A1, B1, C1 and D1 represent to be positioned at one group of parallel on another layer respectively.

With the straight dipped canvas through straight latitude complex tissue structure of EPP-800 as an embodiment draw materials and the twisted weave structure sees the following form:
