Problems solved by technology

Most of the traditional conveyor belts use cotton canvas or polyester cotton canvas as the skeleton material. Due to the low strength, high quality and short service life, the adhesive strength with rubber is not high, and the cloth is easy to peel off or fall off. The quality of the product is poor and the service life is short. , bringing necessary troubles to production and affecting production efficiency

Embodiment Construction

[0016] Specific implementation examples

[0017] The technical solution of the present invention will be further specifically described below through specific examples. A production process for the skeleton of a flame-retardant conveyor belt, the specific steps are as follows:

[0018] (1) Twisting: select high-quality polyester industrial filaments, and use direct twisting method on Alma direct twisting machine;

[0019] (2) Warping: Warp the twisted polyester on SHGA21C warping machine;

[0020] (3) Warp reeding: use G177-300 automatic reeding machine;

[0021] (4) Weaving: Polyester fiber is used as warp yarn, nylon is used as weft yarn, and mat weave is used to weave cloth. The density of warp yarn is 140 / cm, the weft density is 60 / cm, and the warp tightness is 85.4 %, weft tightness 79.9%, total tightness 97%, back beam height 95mm, warp stop height 190mm, opening time 300s;

[0022] (5) Dipping: The dipping is divided into two dippings, the first dipping the primer i...

Abstract

The invention relates to the technical field of conveying bands, in particular to a production technology for a flame-retardant conveying band framework. The production technology comprises the production steps of (1) twisting; (2) beaming; (3) reeding; (4) weaving; (5) gum dipping; (6) drying; (7) sizing; (8) finished product forming. The optimal technical condition is adopted in twisting in the step (1); an OptiMax gripper loom produced by the Picanol Company is adopted in the weaving technology in the step (4); the formula of gum dipping liquid used in a gumming technology in the step (5) consists of a solvent system, an adhesive system and a flame-retardant system, and the gum dipping liquid respectively comprises a mixed solvent, a primer component, a rubber compound component and a chelate resin component. By the adoption of the production technology, the production efficiency is high, and the rejection rate of products is low; the labor cost and the economic cost can be reduced. A conveying band framework material produced by the technology is extremely high in adhesion strength and flame retardancy, and a conveying band has the advantages of high intensity, low quality, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, in particular to a production process for a frame of a flame-retardant conveyor belt. technical background [0002] To convey a large amount of blocky, granular materials and whole materials to the designated position for a long distance, continuously, smoothly and effectively, the solid material conveyor came into being. Conveyor belt plays the role of traction and carrying, and is an important part of solid material conveyor. It has the advantages of safe operation, convenient use, easy maintenance, and low freight. It is widely used in chemical industry, metallurgy, automobile, light industry, textile, agriculture, etc. , coal mines, mines, ports and other industries. The conveyor belt industry contributes to the continuous and efficient production of industry and agriculture and the improvement of people's living standards, and to a certain extent promotes the development of the natio...
