Description

Technical Field

[0001] This utility model belongs to the field of conveyor belt technology, specifically relating to a light-emitting sidewall conveyor belt. Background Technology

[0002] In industries such as chemical engineering, metallurgy, casting, and cement, as well as in tunnel excavation, sidewall conveyor belts are frequently used when conveying large volumes of large-sized materials. These belts, also known as large-angle corrugated sidewall conveyor belts, can continuously transport materials at any angle from 0° to 90°. They have a large conveying angle, wide applicability, and large conveying capacity. It is particularly important to note that they are often required to operate continuously for 24 hours in harsh outdoor environments, including in dark environments at night.

[0003] The low ambient light and decreased vigilance at night increase the potential risks of conveyor belt operation, such as collisions, entanglement, and difficulty in detecting equipment malfunctions. To address the characteristics of nighttime operation, specific safety measures need to be developed across four dimensions: environmental protection, equipment protection, personnel management, and emergency response. Insufficient light at night is a core risk point, requiring lighting and signage to ensure the work area is "visible and identifiable." The difficulty in timely detection of equipment malfunctions at night necessitates the use of "error prevention + early warning" devices to reduce the probability of accidents.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] This invention addresses the aforementioned problems in the prior art by proposing a light-emitting sidewall conveyor belt that enables visibility at night and in dark environments, increases operational safety, and shortens processing time.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0007] A light-emitting sidewall conveyor belt, comprising:

[0008] Baseband;

[0009] Multiple transverse partitions are spaced apart along the length of the baseband;

[0010] Two edge-blocking modules are located on the left and right sides of the baseband;

[0011] The edge-blocking module is composed of multiple edge-blocking segments connected in sequence. The edge-blocking segments have corrugated edges. The corrugated edges have a reinforcing layer, an inner adhesive layer and an outer adhesive layer disposed on the inner and outer sides of the reinforcing layer. An external light-emitting sealing layer is provided between the outer adhesive layers of two adjacent corrugated edges and / or an internal light-emitting sealing layer is provided between the inner adhesive layers of two adjacent corrugated edges.

[0012] In some embodiments of this application, the reinforcing layers of two adjacent corrugated edges overlap to form an overlap portion, and the outer light-emitting sealing layer is located on the outside of the overlap portion and / or the inner light-emitting sealing layer is located on the inside of the overlap portion.

[0013] In some embodiments of this application, an adhesive is applied between the two reinforcing layers of the overlapping portion.

[0014] In some embodiments of this application, the width of the outer light-emitting sealing layer is greater than the width of the overlapping portion and / or the width of the inner light-emitting sealing layer is greater than the width of the overlapping portion.

[0015] In some embodiments of this application, the edge guard also has a base, the corrugated edge is disposed on the base, and an adhesive is coated between the base and the base strip; the reinforcing layer is a mesh polyester fabric layer.

[0016] In some embodiments of this application, the outer light-emitting sealing layer and / or the inner light-emitting sealing layer are made of rubber raw materials and light-emitting powder.

[0017] In some embodiments of this application, the transverse partition has a partition seat, a partition disposed on the partition seat, and an upper light-emitting part is provided on the upper part of the partition.

[0018] In some embodiments of this application, the partition has a vertical portion disposed perpendicular to the partition seat, and an inclined portion that bends along the end of the vertical portion away from the partition and tilts toward the running direction of the baseband, the inclined portion extending further to form an upper light-emitting portion.

[0019] In some embodiments of this application, the partition has a vertical portion disposed perpendicular to the partition seat, and an upper light-emitting portion that is bent and inclined toward the baseband running direction at one end away from the partition along the vertical portion.

[0020] In some embodiments of this application, the thickness of the partition gradually decreases in the upward direction, the upper light-emitting part is inclined in the upward direction, and the length of the inclined extension of the upper light-emitting part is less than 1 / 2 of the height of the partition.

[0021] Compared with existing technologies, the advantages and positive effects of this utility model are: the outer and inner luminescent sealing layers of the edge-blocking module can actively emit light in dark environments, clearly outlining the edge contour and running trajectory of the conveyor belt, preventing personnel from colliding or approaching due to unclear equipment boundaries. It eliminates the need for additional high-power lighting equipment, allowing visualization of equipment status and material conveying positions within the work area, reducing the risk of misoperation due to decreased personnel vigilance. During normal operation, the sealing layer moves synchronously with the conveyor belt; in case of abnormalities, changes in the luminescence state can be used to identify the anomaly, facilitating a shorter problem-solving cycle.

[0036] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0037] See Figures 1-3 This is an embodiment of a light-emitting sidewall conveyor belt proposed in this utility model. A light-emitting sidewall conveyor belt 100 includes: a base belt 10, sidewall modules and transverse partitions 30. Multiple transverse partitions 30 are spaced apart along the length of the base belt 10, and two sidewall modules are provided on the left and right sides of the base belt 10.

[0038] The edge-blocking module is composed of multiple edge-blocking segments 20 connected sequentially. Each edge-blocking segment 20 has a base 21 and a corrugated edge 22. The corrugated edge 22 has a central reinforcing layer 221, an inner adhesive layer 222 and an outer adhesive layer 223 located on both sides of the reinforcing layer 221. An external light-emitting sealing layer 229 is provided between the outer adhesive layers 223 of two adjacent corrugated edge segments 22, and an internal light-emitting sealing layer 228 is provided between the inner adhesive layers 222 of two adjacent corrugated edge segments 22. Figure 2 The inner light-emitting sealing layer 228 and the outer light-emitting sealing layer 229 are shown for easy identification and removal from other parts.

[0039] The outer luminous sealing layer 229 and inner luminous sealing layer 228 of the edge-blocking module can actively emit light in dark environments, clearly outlining the edge contour and running trajectory of the conveyor belt, preventing personnel from colliding or approaching due to unclear equipment boundaries. Without relying on additional high-power lighting equipment, the status of equipment and the location of material conveying within the work area can be visualized, reducing the risk of misoperation due to decreased personnel vigilance. During normal operation, the luminous sealing layer moves synchronously with the conveyor belt; in case of abnormal situations, changes in the luminous state can be used to identify the anomaly, facilitating a shorter problem-solving cycle.

[0040] In some other embodiments, only the internal light-emitting sealing layer 228 or only the external light-emitting sealing layer 229 may be provided.

[0041] In some embodiments of this application, the upper surface of the base belt 10 and the edge 20 are joined and fixed in sections, with each pair of edge 20 sections joined by adhesive. As the core component for blocking material on the side of the conveyor belt, the edge 20's joint is a weak point, prone to cracking and detachment due to material impact. To increase strength, the reinforcing layers 221 of adjacent corrugated edge 22 sections overlap to form an overlap. When material impacts the edge, the impact force can be transmitted through the overlap to the reinforcing layers 221 of the two edge 20 sections, preventing tearing at the joint due to excessive local stress and significantly improving the edge's impact and tensile strength. The outer light-emitting sealing layer 229 is located on the outside of the overlap, and the inner light-emitting sealing layer 229 is located on the inside of the overlap. The light-emitting sealing layer is directly attached to the overlap of the reinforcing layer 221, reducing material friction and direct damage to the light-emitting layer from the external environment, ensuring long-term stable light-emitting function.

[0042] In some embodiments of this application, an adhesive is applied between the two reinforcing layers 221 at the overlap. The adhesive penetrates into the gaps between the reinforcing layers 221, and after curing, tightly bonds the two independent reinforcing layers 221 into a single unit, preventing gaps or relative slippage between the layers. During operation, the reinforcing layers 221 are subjected to complex stresses such as conveyor belt bending and lateral material compression. After the adhesive fills the tiny gaps between the reinforcing layers 221, the stress-bearing area increases significantly, extending the fatigue life of the reinforcing layers 211. The adhesive also possesses a certain degree of flexibility, acting as a buffer between the reinforcing layers 221.

[0043] In some embodiments of this application, the width of the outer light-emitting sealing layer 229 is greater than the width of the overlap portion, and the outer light-emitting sealing layer 229 is fixedly connected to the outer adhesive layer 223. The width of the inner light-emitting sealing layer 228 is greater than the width of the overlap portion. This widened design of the inner and outer light-emitting sealing layers allows for a tighter connection between the overlap portion and the main structure of the edge retainer, significantly improving the overall rigidity of the edge retainer.

[0044] In some embodiments of this application, the corrugated edge 22 is provided on the base 21, and an adhesive is coated between the base 21 and the base strip 10; the reinforcing layer 221 is made of mesh polyester fabric. The outer light-emitting sealing layer 229 and the inner light-emitting sealing layer 228 are made of rubber raw materials and light-emitting powder.

[0045] In some embodiments of this application, the rubber material is molded and vulcanized, then the upper surface of the base strip 10 and the base 21 are polished and coated with adhesive, joined together, and vulcanized again to combine the two. The upper surface of the base strip 10 and the edge 20 are joined in sections, with each pair of edge 20 sections joined by adhesive. When joining each pair of edge 20 sections, the reinforcing layer 221 sandwiched in the middle of the corrugated edge 22 needs to be polished to expose the rubber material, with an exposed width of 15-20mm. Then, the exposed reinforcing layer 221 is coated with adhesive and overlapped with each other. Then, the gap formed by the overlap is filled with a light-emitting rubber material, forming a seal between each pair of edge 20 sections connected by a light-emitting rubber material, namely, an inner light-emitting seal layer 228 and an outer light-emitting seal layer 229; the width of the seal is 20-25mm, and the two edge sections are joined together by a vulcanization process.

[0046] In some embodiments of this application, rubber luminescent powder is added to the rubber compound and a mixed vulcanization process is used to prepare rubber that glows in the dark. Combining inorganic functional materials with organic polymer materials requires balancing the luminescent properties with the mechanical and processing properties of the rubber. Rubber luminescent powder with a particle size of 15-25 μm is used, and its surface is treated with a silane coupling agent to ensure compatibility and dispersibility with the rubber, resulting in a tighter bond with the rubber's molecular chains and preventing agglomeration during mixing. 8%-10% of the sealing compound for the inner luminescent sealing layer 228 and the outer luminescent sealing layer 229 is added by weight, while 2-3% white wax oil is added to improve adhesion.

[0047] In some embodiments of this application, the transverse partition 30, as a core component in the sidewall conveyor belt that prevents materials from sliding down and enables large-angle conveying, must withstand the gravitational compression and impact of the materials. The transverse partition 30 has a partition seat 31 and partitions 32 disposed on the partition seat 31. The upper part of the partition 32 is provided with an upper light-emitting part 321. The upper light-emitting part 321 actively emits light in a dark environment, which can intuitively outline the top height and spacing of the transverse partition 32, allowing the operator to quickly judge the upper limit height and lateral range of material conveying. The visible height of the upper light-emitting part 321 can be used to judge the material filling status. If the upper light-emitting part 321 is completely exposed, it indicates that the material filling rate is low and the feeding speed needs to be increased; if only a small amount of the upper light-emitting part 321 is exposed, it proves that the material filling is full and the current conveying rhythm can be maintained.

[0048] In some embodiments of this application, the partition 32 has a vertical portion 320 disposed perpendicular to the partition seat 31, and an upper light-emitting portion 321 that is bent and inclined toward the running direction of the baseband 10 along one end of the vertical portion 320 away from the partition.

[0049] In some other embodiments of this application, the partition 32 has a vertical portion 320 disposed perpendicular to the partition seat 31, and an inclined portion that is bent at one end of the vertical portion 320 away from the partition and inclined toward the running direction of the baseband 10, and the inclined portion continues to extend to form an upper light-emitting portion 321.

[0050] In some embodiments of this application, the thickness of the partition 32 gradually decreases in the upward direction, the upper light-emitting part 321 is inclined in the upward direction, and the length of the inclined extension of the upper light-emitting part 321 is less than 1 / 2 of the height of the partition 32.

[0051] In some embodiments of this application, the rubber compound is molded and vulcanized using a mold. Then, the upper surface of the base belt 10 and the partition seat 31 of the transverse partition 30 are respectively polished and coated with adhesive compound for mating. The two are then vulcanized again to combine them. The lower part of the transverse partition 30 pushes materials during conveyor belt operation, while the upper part prevents materials from escaping. The lower part of the transverse partition 30 is twice the thickness of the upper part and requires good wear resistance. The transverse partition 30 is molded in a two-stage vulcanization process. After filling the mold to the point where the lower and upper parts of the transverse partition 30 meet, a first stage of vulcanization, or pre-vulcanization, is performed. After pre-vulcanization, a luminescent rubber compound is filled into the upper part of the mold until the mold is full, and the mold is sealed to complete the second stage of vulcanization, followed by demolding.

[0052] In some embodiments of this application, the two-stage vulcanization process is designed for complex structural diaphragms, employing a step-by-step vulcanization technology that divides the vulcanization process into two stages: pre-vulcanization and secondary vulcanization. The lower part of the diaphragm 30 is thicker than the upper part, resulting in slower internal heat dissipation. If vulcanization is performed on both parts in a single step, it is difficult to achieve complete cross-linking of the lower part, leading to "external burnt, internal under-vulcanized" (over-vulcanized surface, under-vulcanized interior). The core objective is to address the uneven vulcanization between the thicker lower part and thinner upper part of the diaphragm during primary vulcanization. In particular, the upper rubber compound, which contains luminescent materials, should be protected against over-vulcanization, as this affects the luminescent function, ultimately ensuring the physical and mechanical properties and operational stability of the diaphragm. Through "step-by-step processing," the lower part of the diaphragm is first shaped and then deeply cross-linked, ultimately achieving uniformity and stability in performance across the different thicknesses of the upper and lower parts of the diaphragm. During the operation of the sidewall belt, the lower part of the diaphragm is buried by materials, rendering its luminescent function largely meaningless, and its formulation requires good wear resistance. The upper part of the diaphragm assumes the luminescent function during the operation of the sidewall belt. Two-stage vulcanization conditions: the first vulcanization temperature is 120~160℃ and the time is 20-25 minutes; the second vulcanization temperature is 180℃ and the time is 120-150 minutes.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
