Embodiment Construction

[0037] see figure 1 As shown in the schematic cross-sectional structure of the present invention, a seamless coiler belt is used to wrap cold-rolled metal sheets, such as steel plates or aluminum plates, wherein the coiler belt is made of endless polyester fabric felt 2 It is a skeleton material, and the front side of the skeleton material is a TPU material layer 1, and the reverse side is an oil-resistant PVC material layer 3.

[0038] The base fabric of the polyester fabric felt is ultra-low shrinkage polyester multifilament in the warp direction and polyester yarn in the weft direction, and the structure is a plain weave structure with one up and one down. , the needle-punched yarn is polyester yarn.

[0039] The Shore hardness of the thermoplastic polyurethane elastomer material is 88-90A.

[0040] The formula of the oil-resistant polyvinyl chloride layer includes the following components in parts by weight:

[0041] 100 parts by weight of polyvinyl chloride paste resin...

Abstract

The invention relates to a seamless wrapper belt which is used for packing a cold rolled sheet metal. The wrapper belt takes an annular polyester fabric felt as a framework material, the front side of the framework material is a thermoplastic polyurethane elastomer material layer, and the back side of the framework material is an oil-resistant polrvinyl chloride material layer. A preparation method of the seamless wrapper belt comprises the following steps of: shaping the felt; firstly coating polyurethane (PU) glue at the front side of the framework material, thenand coating thermoplastic polyurethane elastomer (TPU) materials; firstly coating polyvinyl chloride (PVC) at the back side of the framework material, thenand coating oil-resistant PVC materials; and plastifying and shaping by means of far infrared heating, so that the seamless wrapper belt is manufactured. The invention has the advantages that an annular seamless conveyer belt is offered to a wrapper in a cold rolled sheet metal industry, so that not only can the characteristics of oil resistance and impact resistance of the surface be met, but also various problems caused by a seam can be basically avoided; and the seamless wrapper belt can be customized according to different perimeter sizes required by a customer, so that the personalized requirement of the customer can be met.

Description

technical field [0001] The invention belongs to the technical field of manufacturing a seamless light-duty conveyor belt. The product is mainly used for coiling aid in the cold-rolled metal sheet industry, and in particular relates to a seamless coiling aid belt and a manufacturing method thereof. Background technique [0002] Coiler belts are mainly used in steel mills and aluminum factories. By wrapping the thin plates, the steel plates and aluminum plates are wound on the rollers. During the coiling process, the surface of the belt body of the coiler belts will bear the reaction force exerted by the thin plates. , At the same time, when wrapping, the thin plate and the surface of the coiler belt will slide relative to each other, and the sharp edge on the edge of the thin plate will cause damage to the surface of the belt. Therefore, it is required that the belt body of the coiler belt should be stressed > 30N / mm at 1% extension, and the consistency of extension at eac...
