Novel construction of a conveyor belt with visual monitoring of wear

Abstract

This utility model discloses a novel conveyor belt structure for visually monitoring wear, comprising visually enhanced colored rubber sheets that are fixedly spaced and wrapped around the top, bottom, and sides of the conveyor belt. The conveyor belt consists of a cover layer, a visually enhanced colored adhesive, a belt core layer, and a lower cover layer. The cover layer includes an upper cover layer and a colored upper cover layer, with the colored upper cover layer located between the upper cover layer and the visually enhanced colored adhesive. The visually enhanced colored adhesive is located between the colored upper cover layer and the belt core layer. The lower cover layer is located below the belt core layer, serving as the non-working surface of the conveyor belt, while the upper cover layer serves as the working surface. This utility model, by laying visually enhanced colored rubber sheets, effectively troubleshoots conveyor belt misalignment and slippage, making daily conveyor belt management more visual and simplified. This method also saves on conveyor belt usage costs and, to a certain extent, improves the accuracy of on-site conveyor belt management and reduces the difficulty of on-site management.

Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, and specifically to a new structure conveyor belt for visually monitoring wear. Background Technology

[0002] Commonly used conveyor belts in daily production and life include white, colored, and black conveyor belts. Food-grade conveyor belts typically use white and colored belts, while black conveyor belts are widely used in industrial environments such as cement, coking, metallurgy, chemicals, and steel. The complexity of the on-site operating conditions varies for different types of conveyor belts, resulting in varying degrees of difficulty in on-site management.

[0003] The main challenges in on-site management of conveyor belts lie in the following four aspects:

[0004] 1. The upper cover layer of a typical conveyor belt is the working surface, and its wear level determines the belt's service life. The materials transported by conveyor belts vary greatly under different working conditions, such as material properties, particle size, and hardness, resulting in conveyor belt lifespans ranging from a few months to several years. Currently, most users rely on on-site management personnel to visually assess the wear of the cover layer for conveyor belt inventory and replacement management, a method with a high error rate. Furthermore, investing in wear monitoring devices would increase the operating costs of the conveyor belt.

[0005] 2. The working environment of conveyor belts varies greatly. Especially for industrial conveyor belts, the different working environments such as open-air, corridor, and underground result in different levels of difficulty in on-site management. The dark and confined working environment, the black color of the conveyor belt itself, and the dark color of the materials being transported all increase the difficulty of troubleshooting conveyor belt deviation, slippage, and other faults.

[0006] 3. The operating speed and carrying capacity of the conveyor have a great impact on the on-site management of the conveyor belt. The faster the operating speed and the larger the carrying capacity, the more difficult the on-site management of the conveyor belt becomes.

[0007] 4. The preparation and replacement of conveyor belts all require a certain amount of time from the user to the manufacturer and then to the raw material supplier. Preparing inventory too early may cause the conveyor belts to age due to prolonged storage, affecting their service life; preparing inventory too late may result in untimely replacement of conveyor belts, affecting production progress.

[0008] Existing technologies include some patents that use colored warning adhesive layers to judge the degree of wear, but there is no technical solution that comprehensively judges conveyor belt misalignment, slippage, or wear.

[0009] In order to solve the above problems, this utility model is hereby proposed. Utility Model Content

[0010] The purpose of this invention is to provide a new type of conveyor belt with visible wear monitoring.

[0011] The objective of this utility model can be achieved through the following technical solutions:

[0012] A novel conveyor belt structure for visually monitoring wear includes visually enhanced colored rubber sheets that are fixedly spaced around the top, bottom, and sides of the conveyor belt.

[0013] Preferably, the conveyor belt comprises a cover layer, a visible colored adhesive, a belt core layer, and a lower cover layer; the cover layer includes an upper cover layer and a colored upper cover layer, with the colored upper cover layer located between the upper cover layer and the visible colored adhesive; the visible colored adhesive is located between the colored upper cover layer and the belt core layer; the lower cover layer is located below the belt core layer, the lower cover layer is the non-working surface of the conveyor belt, and the upper cover layer is the working surface of the conveyor belt.

[0014] Furthermore, both the upper and lower cover adhesives are the colors required by the conveyor belt user, and the colored upper cover adhesive, the visible colored adhesive, and the visible enhanced colored adhesive sheet are all colored.

[0015] Preferably, the color of the visible colored adhesive is different from the color of the colored overlay adhesive, and the thickness of the visible colored adhesive is less than the thickness of the colored overlay adhesive.

[0016] Beneficial technical effects:

[0017] This utility model effectively troubleshoots conveyor belt misalignment and slippage by laying a visibility-enhancing colored rubber sheet, making the daily management of the conveyor belt more visual and simple. This method can also save on the cost of using the conveyor belt and improve the accuracy of on-site management and reduce the difficulty of on-site management to a certain extent.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1-2 As shown, a novel conveyor belt structure for visually monitoring wear includes a visually enhanced colored adhesive sheet 6, which is fixedly spaced and wrapped around the top, bottom, and sides of the conveyor belt. The visually enhanced colored adhesive sheet 6 uses small-sized colored adhesive, with a color clearly distinguishable from the overall appearance of the conveyor belt. By laying the visually enhanced colored adhesive sheet 6, using thin, brightly colored adhesive and wrapping it around the top, bottom, and sides of the conveyor belt at fixed intervals, the user can more clearly locate the belt during operation, even in dark environments and at high speeds. This allows for easy detection of faults such as belt misalignment and slippage, reducing the difficulty of on-site conveyor belt management and improving its accuracy.

[0024] The conveyor belt consists of a cover layer 7, a visible colored adhesive 5, a belt core layer 4, and a lower cover adhesive 3. The cover layer 7 includes an upper cover adhesive 1 and a colored upper cover adhesive 2, with the colored upper cover adhesive 2 located between the upper cover adhesive 1 and the visible colored adhesive 5. The visible colored adhesive 5 is located between the colored upper cover adhesive 2 and the belt core layer 4. The lower cover adhesive 3 is located below the belt core layer 4. The lower cover adhesive 3 is the non-working surface of the conveyor belt, and the upper cover adhesive 1 is the working surface of the conveyor belt.

[0025] The colored top cover adhesive 2 is clearly different in color from the top cover adhesive 1. The colored top cover adhesive 2 has the same physical performance indicators as the top cover adhesive 1. The width and length of the colored top cover adhesive 2 are consistent with those of the top cover adhesive 1. It is laid between the top cover adhesive 1 and the visible colored adhesive 5. The visible colored adhesive 5 is a different color from the colored top cover adhesive 2. The width and length of the visible colored adhesive 5 are consistent with those of the colored top cover adhesive 2, but the thickness is less than that of the colored top cover adhesive. It is laid between the colored top cover adhesive 2 and the core layer 4. The core layer 4 is a fabric core, a steel wire rope core, or other materials. A tear-resistant reinforcement layer can also be added as needed.

[0026] If users find that the working surface of the conveyor belt is colored differently from the belt's appearance, they should pay close attention to that area and carry out local repairs according to the production schedule. At the same time, the conveyor belt preparation process should be initiated.

[0027] When the visible colored adhesive 5 is found exposed on the conveyor belt working surface during routine inspections, the process of replacing the old belt with a new one needs to be initiated. Normally, the top cover adhesive 1 is black. In contrast, the colored top cover adhesive 2 and the visible colored adhesive 5, due to their vibrant colors, enhance the visibility of on-site conveyor belt management (especially in dark and confined environments), thereby reducing the difficulty and increasing the accuracy of on-site management. Furthermore, the different colors of the colored top cover adhesive 2 and the visible colored adhesive 5 visualize the user's stock preparation and replacement initiation markers, making management simpler and more convenient.

[0028] This invention does not require additional devices or systems for monitoring wear. Instead, it achieves effective visual monitoring of conveyor belt wear by simply changing the color of the conveyor belt cover rubber and adding a colored adhesive layer. This also enables visible management of conveyor belt preparation and replacement phases. Users do not need to make any additional investment in the conveyor belt, and the monitoring of conveyor belt wear is highly visible and accurate.

[0029] All colored adhesives are produced using conventional raw materials and will not increase the manufacturing cost of the conveyor belt.

[0030] Of these, the upper cover adhesive 1 and lower cover adhesive 3 are the colors required by the conveyor belt user. The colored upper cover adhesive 2, the visible colored adhesive 5, and the visible reinforced colored adhesive sheet 6 are all colored, with a significant difference in color from the conveyor belt body. The color of the visible colored adhesive 5 differs from the color of the colored upper cover adhesive 2, and the thickness of the visible colored adhesive 5 is less than the thickness of the colored upper cover adhesive 2. The thickness of the colored upper cover adhesive 2 is less than the thickness of the upper cover adhesive 1; the sum of their thicknesses is the thickness of the upper cover layer 7. Since the colored upper cover adhesive 2 and the upper cover adhesive 1 both belong to the upper cover layer 7, the physical performance parameters of the colored upper cover adhesive 2 must be consistent with those of the upper cover adhesive 1 to meet the user's requirements.

[0031] The skeleton material of the core layer 4 involved in this utility model is fabric, steel wire rope or other materials. A tear-resistant reinforcement layer can also be added as needed. Its structure is not limited by other colored adhesives.

[0032] Here is a suggested conveyor belt structure for this utility model: Taking a black industrial conveyor belt as an example, if the upper cover layer is required to be 5mm thick, the thickness of the colored upper cover adhesive can be 2mm and the color can be blue, the thickness of the visible colored adhesive adhesive can be 1mm and the color can be yellow, and the thickness of the visible enhancement colored adhesive sheet can be 1mm and the color can be yellow, with a laying spacing of 2m. Users record the date the conveyor belt turns blue in their inspection logbook and initiate the conveyor belt repair and replenishment process. If yellow is found on the conveyor belt during routine inspections, the old belt should be immediately removed from the production line and replaced with a new belt. The time difference between these two events can serve as a safe time for replenishing and replacing conveyor belts for this production line. The visible enhancement yellow adhesive sheet effectively assists on-site management personnel in troubleshooting. Other similar structural embodiments also fall within the scope of protection of this utility model.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
