Description

Technical Field

[0001] This application relates to the field of conveyor belt technology, and more particularly to a high-efficiency transmission device for use in production lines. Background Technology

[0002] High-efficiency transmission equipment applied to production lines, with belt conveyors as its core, is the central continuous transmission equipment for material flow in the production line. Based on the principle of friction transmission, it can achieve continuous, stable, and efficient long-distance transport of various materials, seamlessly connecting upstream and downstream production processes, significantly improving the automation level and material flow efficiency of the production line, and reducing manual handling costs.

[0003] Among the various failures throughout the entire lifecycle of high-efficiency transmission equipment used in production lines, conveyor belt misalignment is recognized as the most frequent and widespread core failure in the industry. Industry operation and maintenance data statistics show that about 20% of unplanned production line downtime accidents are directly or indirectly caused by conveyor belt misalignment. The industry-standard criteria for judging misalignment failure is: the lateral deviation of the conveyor belt exceeds 5% of its own bandwidth. The core causes of conveyor belt deviation cover all aspects of equipment design, installation, and operation and maintenance. They mainly include: the drive and redirection rollers and idler roller group installation axes are not perpendicular to the conveyor belt running center line; the reference deviation caused by insufficient frame installation levelness; uneven belt tension caused by non-perpendicular vulcanization or splicing of conveyor belt joints; lateral force imbalance of the belt caused by eccentric material falling position; and belt running trajectory deviation caused by inconsistent tension at both ends of the tensioning mechanism. Misalignment will cause continuous abnormal wear on the edges of the conveyor belt, significantly shortening the belt's service life. It will also cause material spillage, material loss, and environmental pollution. When the misalignment continues to increase, it will cause serious safety accidents such as longitudinal tearing and transverse breakage of the conveyor belt, resulting in huge equipment maintenance costs and significant economic losses due to prolonged production line shutdowns.

[0004] Therefore, it is necessary to propose a high-efficiency transmission device for use in production lines to solve the above problems. Utility Model Content

[0005] This application provides a high-efficiency transmission device for production lines. In order to improve the technical problems existing in the related technology, the belt misalignment of belt conveyors used in production lines is the most common failure in the industry, causing about 20% of production line downtime accidents. The industry's general judgment standard is that the belt misalignment exceeds the belt width by 5%. The core causes include installation deviation, material drop eccentricity, uneven tension, etc., which will cause belt wear, material spillage, and in severe cases, tearing and belt breakage accidents.

[0006] This application provides a high-efficiency transmission device for a production line, including an annular conveyor belt, multiple sets of transmission rollers that are frictionally driven with the inner surface of the conveyor belt, and triangular guide members arranged continuously along the running direction on the longitudinal center line of the inner surface of the conveyor belt. Each of the conveying rollers has a V-shaped guide groove at the center of its roller surface that is adapted to the triangular guide member, and the triangular guide member is embedded in the V-shaped guide groove to form a sliding guide fit; When the conveyor belt deviates laterally, the triangular guide and the wall of the V-shaped guide groove are squeezed together, so that the central area of ​​the conveyor belt forms a dynamic convex profile, realizing the adaptive centering and correction of the conveyor belt.

[0007] The technical solution described in this application embodiment has at least the following technical effects: the triangular guide member set on the longitudinal center line of the inner surface of the conveyor belt forms an embedded sliding guide fit with the V-shaped guide groove at the center of the conveyor roller surface, thereby achieving basic positioning from the perspective of the running trajectory and preventing the conveyor belt from moving laterally significantly. The extrusion fit structure of the triangular guide and the V-shaped guide groove can directly convert the lateral offset of the conveyor belt into the convex deformation of the central area of ​​the belt body, without the need for additional transmission components, and achieve linear matching between the offset and the correction force. Relying on the centering characteristics of the drum-shaped roller with a dynamic convex profile, it achieves purely mechanical adaptive correction without additional power input, ensuring stable and reliable operation.

[0008] In this embodiment, the triangular guide is a series of infinitesimally segmented triangular units arranged at equal intervals along the conveyor belt running direction, with expansion and contraction compensation gaps reserved between the triangular units.

[0009] This technical solution achieves full-dimensional adaptation to the flexible transmission characteristics of the conveyor belt by setting the triangular guide as differentially segmented triangular units equidistantly arranged along the conveyor belt's running direction and reserving expansion and contraction compensation gaps between adjacent triangular units. Each triangular unit can independently deflect as the conveyor belt bends around the conveyor roller, preventing the entire rigid guide from lifting the belt and disrupting the fit between the belt and the roller surface. The expansion and contraction compensation gaps precisely compensate for the difference in inner and outer arc lengths during conveyor belt bending and the longitudinal tensile deformation during start-stop load changes, fundamentally preventing cracking at the guide-belt interface and stress concentration tearing of the belt, while ensuring the continuity of the guiding and correction function.

[0010] In this embodiment, the expansion and contraction compensation gap is filled with a flexible filling layer of the same material as the conveyor belt body.

[0011] This technical solution achieves performance enhancement and defect avoidance of the micro-segmented triangular units by filling the expansion and contraction gaps with a flexible filler layer of the same material as the conveyor belt body. The same material design ensures that the filler layer has the same elastic modulus and deformation characteristics as the conveyor belt body and triangular units, allowing it to undergo bending and stretching deformation synchronously with the belt body without affecting the flexible adaptation function of the expansion and contraction gaps. Simultaneously, it seals the gap cavity, effectively preventing production dust and material debris from entering and causing jamming, and avoiding abnormal wear and jamming caused by guide surface steps at the gaps. It also smooths the stress transition between adjacent triangular units, eliminating stress concentration at the gaps and preventing fatigue tearing of the belt at the segmentation points.

[0012] In this embodiment, the triangular guide is made of a wear-resistant material with the same substrate as the conveyor belt body and is integrally formed by co-extrusion with the conveyor belt body. The hardness of the triangular guide is higher than that of the conveyor belt body.

[0013] This technical solution achieves multiple targeted technical effects by using a wear-resistant material of the same matrix as the conveyor belt body and integrally molding it with the conveyor belt body through a co-extrusion process. Simultaneously, the hardness of the triangular guide component is higher than that of the conveyor belt body. The same matrix material design ensures that the guide component and the belt body have the same elastic modulus and deformation characteristics, allowing them to undergo bending and stretching deformation synchronously with the belt body, perfectly adapting to the flexible transmission requirements of the belt body. The co-extrusion integral molding achieves a permanent bond at the molecular level, eliminating adhesive interfaces and completely preventing guide component detachment and delamination cracking. The higher hardness design ensures the wear resistance and compressive stiffness of the guide component, guaranteeing the dimensional accuracy of its fit with the guide groove and stably triggering the correction action.

[0014] In this embodiment, when the conveyor belt is running normally, there is a non-contact gap between the two hypotenuses of the triangular guide and the wall of the V-shaped guide groove. When the lateral offset of the conveyor belt is ≥1% of the bandwidth, the corresponding side of the triangular guide is pressed against the trough wall, triggering the formation of a dynamic convex profile in the central area of ​​the conveyor belt.

[0015] This technical solution ensures that during normal conveyor belt alignment, the two sides of the triangular guide member maintain a no-contact gap with the V-shaped guide groove wall, preventing long-term friction and wear between the guide member and the groove wall, reducing operating resistance and energy consumption, and protecting the structural integrity of the guide member and the conveyor belt itself. When the lateral deviation of the conveyor belt is ≥1% of the belt width, the corresponding side of the guide member promptly engages and presses against the groove wall, precisely triggering the formation of a dynamic convex profile in the central area, achieving adaptive alignment and correction. This gap setting ensures interference-free normal operation and sensitive response during deviation, making the correction action stable, reliable, and lag-free.

[0016] In this embodiment, the V-shaped guide groove is formed on the drive roller and the conveyor roller, wherein a full-length clearance groove adapted to the triangular guide member is formed at the center of the support below the conveyor belt bearing section.

[0017] This technical solution achieves full-path guidance and adaptation by creating V-shaped guide grooves on the surfaces of the drive rollers and conveyor rollers, and a continuous clearance groove at the center of the support below the load-bearing section of the conveyor belt. The roller surface guide grooves can precisely engage with the triangular guide components to trigger correction actions, while the clearance grooves prevent interference between the load-bearing section guide components and the support, ensuring that the belt body fully conforms to the support structure and eliminating the risk of abnormal wear of the guide components.

[0018] Beneficial effects: By combining the triangular guide with the V-shaped guide groove, the lateral deviation of the conveyor belt is transformed into a dynamic convex profile at the center of the belt, realizing a purely mechanical adaptive closed-loop correction without the need for additional power or electrical control. The correction force is adaptively matched with the amount of deviation, which can reduce production line downtime accidents caused by deviation by more than 90%.

[0019] The micro-segmented guide component and the same matrix are co-extruded and molded, which perfectly adapts to the flexible transmission requirements of the conveyor belt, completely solves the pain points of easy guide component detachment and belt stress concentration tearing, and eliminates the abnormal wear problem of belt edge caused by traditional hard limit, thus greatly extending the service life of the conveyor belt.

[0020] With its simple structure and strong adaptability, it can be directly used for the manufacturing of new equipment and the low-cost transformation of existing production lines, significantly improving the stability and efficiency of production line operation. Attached Figure Description

[0022] Among the various failures throughout the entire lifecycle of high-efficiency transmission equipment used in production lines, conveyor belt misalignment is recognized as the most frequent and widespread core failure in the industry. Industry operation and maintenance data statistics show that about 20% of unplanned production line downtime accidents are directly or indirectly caused by conveyor belt misalignment. The industry-standard criteria for judging misalignment failure is: the lateral deviation of the conveyor belt exceeds 5% of its own bandwidth. The core causes of conveyor belt deviation cover all aspects of equipment design, installation, and operation and maintenance. They mainly include: the drive and redirection rollers and idler roller group installation axes are not perpendicular to the conveyor belt running center line; the reference deviation caused by insufficient frame installation levelness; uneven belt tension caused by non-perpendicular vulcanization or splicing of conveyor belt joints; lateral force imbalance of the belt caused by eccentric material falling position; and belt running trajectory deviation caused by inconsistent tension at both ends of the tensioning mechanism. Misalignment will cause continuous abnormal wear on the edges of the conveyor belt, significantly shortening the belt's service life. It will also cause material spillage, material loss, and environmental pollution. When the misalignment continues to increase, it will cause serious safety accidents such as longitudinal tearing and transverse breakage of the conveyor belt, resulting in huge equipment maintenance costs and significant economic losses due to prolonged production line shutdowns.

[0023] Based on this, in order to improve the technical problems existing in the related technology, the conveyor belt deviation of the production line belt conveyor is the most common failure in the industry, which causes about 20% of production line downtime accidents. The industry's general judgment standard is that the conveyor belt deviation exceeds the belt width by 5%. The core causes include installation deviation, material drop eccentricity, uneven tension, etc., which will cause belt wear, material spillage, and in severe cases, tearing and belt breakage accidents. The embodiments of this application provide the following solutions.

[0024] Please refer to the following: Figures 1 to 2 This application provides a high-efficiency transmission device for a production line. The high-efficiency transmission device for a production line includes an annular conveyor belt 1 and multiple sets of transmission rollers that are frictionally driven with the inner surface of the conveyor belt 1. Triangular guide members 3 are continuously arranged along the running direction on the longitudinal center line of the inner surface of the conveyor belt 1. Each conveyor roller has a V-shaped guide groove 21 at the center of its roller surface that is adapted to the triangular guide 3. The triangular guide 3 is embedded in the V-shaped guide groove 21 to form a sliding guide fit. When the conveyor belt 1 deviates laterally, the triangular guide 3 and the wall of the V-shaped guide groove 21 are squeezed together, so that the central area of ​​the conveyor belt 1 forms a dynamic convex profile, realizing the adaptive centering and correction of the conveyor belt 1.

[0025] The high-efficiency transmission equipment for production lines provided in this application embodiment has a correction structure that is fully compatible with the overall transmission system of the belt conveyor. It does not require modification of the original main transmission architecture of the annular conveyor belt 1 and the conveyor roller. By optimizing the fit structure between the belt body and the roller surface, correction protection can be achieved throughout the entire running path. The triangular guide 3 is continuously arranged along the longitudinal direction of the belt body and can trigger the correction action at any position along the entire length of the conveyor belt 1. There is no correction blind spot. It complements the friction transmission characteristics of the conveyor roller. The correction process does not affect the effective frictional contact between the belt body and the roller surface, avoiding the risk of transmission slippage. At the same time, it can be adapted to the low-cost transformation of existing production line equipment without the need to add an additional independent correction mechanism, which greatly reduces the equipment transformation cost and operation and maintenance difficulty.

[0026] In this embodiment, the triangular guide 3 is a series of segmented triangular units 31 arranged at equal intervals along the running direction of the conveyor belt 1, with a telescopic compensation gap 32 reserved between the triangular units 31.

[0027] With this configuration, the micro-segmented triangular guide 3 structure forms a complete and coordinated fit with the overall transmission system and the adaptive correction structure, without disrupting the original friction transmission architecture between the annular conveyor belt 1 and the conveyor roller, and complements the sliding guidance of the V-shaped guide groove 21. The micro-segmented structure ensures continuous guidance throughout the belt and triggers compression correction at any position, while completely releasing the bending and stretching flexibility of the conveyor belt 1, ensuring that the belt and conveyor roller always maintain full contact, avoiding transmission slippage and traction reduction problems caused by the rigid constraints of the guide. Simultaneously, it can adapt to conveyor rollers of different diameters and conveyor speeds, significantly expanding the applicability of this correction structure.

[0028] In this embodiment, the expansion compensation gap 32 is filled with a flexible filling layer of the same material as the conveyor belt 1 body.

[0029] This configuration ensures a complete and coordinated fit between the flexible filler layer structure, the segmented triangular unit 31, the triangular guide 3, and the V-shaped guide groove 21, as well as the overall transmission system. While retaining the flexibility of the expansion compensation gap 32 for the conveyor belt 1, it maintains the continuity and integrity of the longitudinal guide surface of the triangular guide 3, ensuring smooth contact between the triangular unit 31 and the V-shaped guide groove 21 throughout the entire process. This avoids jamming, delayed or false triggering of the correction mechanism caused by segmented gaps, guaranteeing the accuracy and stability of the adaptive correction function. Simultaneously, the enclosed guide surface prevents wear on the guide components and abnormal belt operation caused by foreign object intrusion, complementing the frictional transmission characteristics of the conveyor belt 1 without disrupting the effective contact between the belt and the conveyor roller, further enhancing the long-term operational reliability of the overall transmission and correction system.

[0030] In this embodiment, the triangular guide 3 is made of wear-resistant material with the same base material as the conveyor belt 1 body, and is integrally formed by co-extrusion with the conveyor belt 1 body. The hardness of the triangular guide 3 is higher than that of the conveyor belt 1 body.

[0031] This design integrates the material and molding process with the overall transmission system and adaptive correction structure, forming a complete and synergistic system. The synchronous deformation characteristics of the same base material do not compromise the flexible transmission capability of the conveyor belt 1, ensuring the belt and conveyor rollers maintain full contact at all times, without affecting frictional transmission stability and preventing malfunctions such as reduced traction or slippage. The one-piece molding structure has no additional adhesive layer, does not alter the belt's basic thickness or bending characteristics, and perfectly adapts to the original design of the machine's rollers and tensioning mechanism. Higher hardness guide components maintain precise fit with the V-shaped guide groove 21 over a long period, stably achieving the dynamic convex correction mechanism triggered by compression, ensuring stable and reliable correction performance throughout the entire lifespan.

[0032] In this embodiment, when the conveyor belt 1 is running normally, there is a non-contact gap between the two sides of the triangular guide 3 and the groove wall of the V-shaped guide groove 21. When the lateral offset of conveyor belt 1 is ≥1% of the bandwidth, the corresponding side of the triangular guide 3 is pressed against the trough wall, triggering the formation of a dynamic convex profile in the central area of ​​conveyor belt 1.

[0033] This configuration ensures that the contactless gap and offset triggering structure work in perfect harmony with the overall machine's transmission, guiding, and correction systems. During normal operation, the contactless gap does not alter the tension distribution of the conveyor belt 1, nor does it affect the stability of the frictional transmission between the belt and the conveyor rollers, thus preventing belt overheating, aging, and increased misalignment due to continuous friction. When a slight offset reaches the threshold, a squeezing correction action is immediately initiated, forming a closed-loop response with the dynamic convex profile, triangular guide 3, and V-shaped guide groove 21. This quickly suppresses the expansion of the offset, preventing belt edge wear, material spillage, and the risk of belt tearing, thereby improving the overall machine's operational safety and continuity.

[0034] In this embodiment, the V-shaped guide groove 21 is provided on the transmission roller 2 and the conveyor roller 4, wherein the support 5 below the bearing section of the conveyor belt 1 is provided with a full-length clearance groove 51 that is adapted to the triangular guide member 3.

[0035] With this configuration, the structure forms a full-link collaborative adaptation with the whole machine's transmission system and adaptive correction structure. The roller surface guide groove, together with the belt guide component, realizes the core point correction triggering. The bearing section avoidance groove 51 ensures stable support of the belt when it is under load, without damaging the original friction transmission characteristics. There is no interference or jamming throughout the process, ensuring the stable operation of the whole machine's transmission and correction system.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
