Embodiment Construction

[0048] see image 3 As shown in the schematic cross-sectional structure of the conveyor belt of the present invention, a conveyor belt with a warp-knitted biaxial fabric as the skeleton includes a fabric reinforced skeleton, a covering layer and a covering layer, wherein the reinforced skeleton includes a warp-knitted Biaxial fabric and woven fabric, the conveyor belt is sequentially composed of woven fabric 4, polyvinyl chloride bonding layer 3, warp-knitted biaxial fabric 2 and polyvinyl chloride 1 surface layer from bottom to top.

[0049]In the woven fabric, the weft yarns are polyester monofilaments with a diameter of 0.3 mm to ensure the lateral stability of the conveyor belt, and the weft weaving density is 35 to 40 strands / inch; the warp yarns are polyester monofilaments The yarn has a weaving density of 20-25 strands / inch in the warp direction, and the filament is an ultra-low shrinkage filament with a shrinkage rate of 2.0-3.5%, and its linear density is 950-1500dtex...

Abstract

The invention relates to a conveyer belt taking a warp-knitted bi-axial fabric as a framework and a manufacturing method thereof. The conveyer belt sequentially comprises a woven fabric, a polyvinyl chloride laminated layer, the warp-knitted bi-axial fabric and a polyvinyl chloride surface layer from bottom to top. The manufacturing method comprises the following steps of: finalizing the design of the woven fabric, carrying out primary coat, and coating polyvinyl chloride paste resin to form the laminated layer; finalizing the design of the warp-knitted bi-axial fabric, jointing with the woven fabric of the bottom layer; and carrying out surface layer coating on the warp-knitted bi-axial fabric to form the conveyer belt structure of a double-framework double- polyvinyl chloride layer. The utilization rate of the intensity of warp in the warp-knitted bi-axial fabric reaches the highest, and the warp is always in a straight state and does not have creep relaxation. Self-cementing between the PVC (polyvinyl chloride) surface layer and the PVC laminated layer can be formed, the primary coat process is left out, the racking strength is greatly enhanced, the requirements on roll diameter and tension length of a conveyer are reduced, the service life is improved, and the cost is 40% lower than the woven fabric.

Description

technical field [0001] The invention relates to a new type of reinforced skeleton of a conveyor belt. The light conveyor belt woven with the reinforced skeleton not only meets the requirement of higher elongation force, but also greatly reduces its production cost, and has great development space and prospects. Background technique [0002] The conveyor belt is mainly composed of a reinforced skeleton and a surface covering material. The reinforced skeleton occupies an important position and bears the joint force from the surface covering material and the outside world, which plays a role in improving the breaking strength of the conveyor belt and limiting its deformation. Therefore, the reinforced skeleton determines the performance, service life and value of the finished conveyor belt to a large extent. [0003] During the long-term use of the conveyor belt, there will be a "phenomenon" of running long. The reason is that the conveyor belt is pre-tensioned so that the len...
