DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0044] Embodiment 1

[0045] The embodiment provides an oil-resistant puncture-resistant conveying belt, comprising:

[0046] a fabric core 1;

[0047] a cover glue outer sleeve 2, the cover glue outer sleeve 2 is arranged outside the fabric core 1;

[0048] a protective structure 3, the protective structure 3 is arranged on the cover glue outer sleeve 2, the protective structure 3 comprises a cover glue plate 31 and an oil absorbing cotton pad 32, the oil absorbing cotton layer is arranged inside the cover glue plate 31, and the cover glue plate 31 is densely covered with fine holes 4;

[0049] wherein, the cover glue end face is formed with a mounting groove 5, the cover glue plate 31 and the oil absorbing cotton pad 32 are arranged in the mounting groove 5, and the end face of the mounting groove 5 is protruded to the outside.

[0050] The embodiment can be seen that an oil-resistant puncture-resistant conveying belt comprises a fabric core 1, a cover glue outer sleeve 2 and a protective structure 3;

[0051] The cover glue outer sleeve 2 is connected outside the fabric core 1, the cover glue outer sleeve 2 is used for protecting the fabric core 1, so that the fabric core 1 can be prevented from being damaged by materials in the process of conveying materials, the cover glue outer sleeve 2 is formed with a protrusion extending to the outside at the port and narrowing the port of the mounting groove 5, and the end face of the mounting groove 5 is slightly raised to form an arched surface, and the protective structure 3 is mounted on the mounting groove 5;

[0052] The protective structure 3 includes a cover rubber plate 31 and an oil absorption cotton pad 32, the cover rubber plate 31 and the oil absorption cotton pad 32 are consumables, the cover rubber plate 31 is densely provided with fine holes 4 (the two ends of the fine holes 4 are provided with large ports to facilitate oil absorption), the cover rubber plate 31 is connected in the mounting groove 5, the two sides of the cover rubber plate 31 are provided with extension edges, the extension edges are limited and fixed between the closing port of the mounting groove 5, the oil absorption cotton pad 32 is arranged between the cover rubber plate 31 and the end surface of the mounting groove 5 and is fixed when the cover rubber plate 31 is connected with the mounting groove 5.

[0053] The conveying belt is usually used in cooperation with rollers, wheels and the like, and is often bent in the use process. The cover rubber plate 31 directly contacts the material, thereby avoiding damage to the cover rubber sleeve 2 and protecting the fabric core 1 from damage by the material. In the use process, the upper side of the conveying belt is provided as the A surface, and the lower side is provided as the B surface. The cover rubber plate 31 on the A surface directly contacts the material, and the oil on the material falls into the mounting groove 5 through the fine holes 4 densely arranged on the cover rubber plate 31 and is absorbed by the oil absorption surface. By controlling the flow direction of the oil, the splashing of the oil is prevented. After the conveying belt passes through the rollers and is bent, the A surface faces downward, and the B surface faces upward. The raised arched surface of the mounting groove 5 on the A surface side extrudes the oil absorption cotton pad 32 in the bending process, so that the oil is extruded from the oil absorption cotton pad 32 and flows out through the fine holes 4. The B surface faces upward and contacts the material to absorb oil, thereby achieving the effects of oil absorption and oil control and achieving the purpose of oil resistance.

[0054] The protective structure 3 achieves the purpose of puncture resistance by arranging the cover rubber plate 31. The oil absorption cotton pad 32 arranged between the cover rubber plate 31 and the end surface of the mounting groove 5 absorbs the oil, and the raised end surface of the mounting groove 5 extrudes the oil in the bending process of the conveying belt, thereby achieving the effect of controlling the flow direction of the oil and achieving the purpose of oil resistance.
