Description

Technical Field

[0001] The utility model belongs to the technical field of felt belts, and in particular relates to a single-sided felt belt with a flame-retardant structure. Background Art

[0002] Felt belts are a new type of conveyor belt widely used in the transportation industry. Felt belts are generally made of high-density cotton cloth that is dipped in glue and composited. They have high strength, low ductility, tensile strength, wear resistance and certain toughness. For example, a felt belt with a hidden steel buckle interface is recorded in the Chinese patent application with application number CN201821045828.9. In this patent, the felt belt can be connected by designing a hidden steel buckle.

[0003] The structure of traditional felt belts is relatively simple and their fire retardant properties are average. Once the felt belt is contaminated with a fire source, the entire belt will easily burn rapidly in a short period of time, and it is difficult to control the fire. Therefore, it is necessary to design a composite felt belt to solve this problem. Utility Model Content

[0004] The utility model aims to provide a single-sided felt belt with a flame retardant structure to solve the problem of poor fire retardant performance of the existing single-structure felt belt proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a single-sided felt belt with a flame-retardant structure, comprising a felt belt unit A and a felt belt unit B, wherein an inner core layer is arranged inside the felt belt unit A and the felt belt unit B, wherein the inner core layer comprises an interlayer, a cowhide inner sheet and an asbestos fiber sheet, wherein the interlayer is arranged inside the felt belt unit A and the felt belt unit B, wherein the cowhide inner sheet is fixed to the inner bottom of the interlayer, wherein the asbestos fiber sheet is fixed to the inner top of the interlayer, wherein a connecting component is arranged between the felt belt unit A and the felt belt unit B, wherein the connecting component comprises an extension part A, an extension part B, a nylon cloth, a steel buckle and a buckle groove, wherein the extension part A is fixed to one end of the felt belt unit A, wherein the extension part B is fixed to the end of the felt belt unit B opposite to the felt belt unit A, wherein the extension part A is attached to the extension part B, wherein the steel buckle is connected to the bottom of the extension part A through the nylon cloth, and wherein the steel buckle is hooked with the buckle groove arranged on the extension part B.

[0006] Preferably, the inner core layer further comprises a card block and a card slot, wherein the card block is fixed to the bottom surface of the asbestos fiber sheet and inserted into the card slot provided on the top surface of the cowhide inner sheet.

[0007] Preferably, the inner core layer further comprises a glue layer, and the glue layer is filled between the interlayer and the cowhide inner sheet.

[0008] Preferably, the connecting component also includes a bottom groove A and a bottom groove B, the bottom groove A is opened on the bottom surface of the extension part A, the steel buckle is connected inside the bottom groove A, the bottom groove B is opened on the bottom surface of the extension part B, and the buckle groove is opened on the top of the bottom groove B.

[0009] Preferably, the connecting component also includes an inner groove, which is opened on the inner wall of one end of the bottom groove A, one end of the nylon cloth is fixedly connected to the inside of the inner groove, and the other end is fixedly connected to the steel buckle.

[0010] Preferably, the connecting assembly further comprises a steel ring, the steel ring is fixed inside the buckle groove, and the steel buckle is hooked with the steel ring.

[0011] Preferably, the bottom of the felt belt unit A and the felt belt unit B are both provided with anti-slip components, and the anti-slip components include a rubber base pad and a suction hole, the rubber base pad is fixedly connected to the bottom surface of the felt belt unit A and the felt belt unit B, and the suction hole is opened on the bottom surface of the rubber base pad.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By arranging an inner core layer inside the felt belt unit A, the asbestos fiber sheets contained in the inner core layer have good fire retardant properties. This design improves the overall fire retardant properties of the felt belt, thereby preventing the felt belt from burning too quickly, resulting in a fire that is difficult to control. At the same time, the cowhide inner sheet inside the inner core layer can improve the overall toughness and strength of the felt belt. Compared with a single-structure felt belt, the composite felt belt has significantly improved fire retardant properties and strength and toughness. BRIEF DESCRIPTION OF THE DRAWINGS
