Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, and more specifically, to a horseshoe-shaped mesh belt structure for auxiliary reinforcement. Background Technology

[0002] In the production, packaging, and storage of frozen foods, metal conveyor belts serve as the primary material handling structure, widely used in quick-freezing conveyor lines, cold chain sorting systems, and refrigerated packing stations. Traditional conveyor belt structures typically consist of multiple support struts (load-bearing members) and spirals wound around them, secured and limited at the ends by connectors.

[0003] Conventional conveyor belt structures typically use only a single connecting plate at the connection point at the end of the line, which has limited connection strength and resistance to lateral deformation. However, with the continuous increase in conveyor speed, especially under high-speed linear operation, the conveyor belt is subjected to greater longitudinal tension, lateral vibration, and impact loads, making it more prone to stress concentration, which can lead to component deformation or even breakage, greatly affecting the reliability and lifespan of the equipment.

[0004] Therefore, there is an urgent need for a new type of mesh belt structure that can improve the connection strength and resistance to lateral deformation under high linear speed conveying conditions, thereby ensuring the stable and efficient operation of the conveying system. Utility Model Content

[0005] The purpose of this application is to provide an auxiliary reinforcement horseshoe mesh belt structure, which effectively solves the problem of easy breakage of high-speed straight transport mesh belts by setting horseshoe connecting plates in parallel, thereby improving transport safety and reliability.

[0006] A horseshoe-shaped mesh belt structure for auxiliary reinforcement includes:

[0007] Multiple force bones spaced apart along the bandwidth direction;

[0008] A spiral spanning between adjacent force members;

[0009] And a horseshoe-shaped connecting plate that is inserted into and fixed to the force frame and used for end bearing and limiting;

[0010] At least two horseshoe connecting plates are arranged side by side on both sides of the spiral, that is, at both ends of each force bone. The lower end of the horseshoe connecting plate passes through one of the force bones, and the upper end of the horseshoe connecting plate passes through the force bone located above and adjacent to the force bone.

[0011] The parallel horseshoe connecting plates are provided with through holes at the top and bottom for the force-bearing bones to pass through, thereby improving the strength of the directional connection and the resistance to lateral deformation under high linear speed conveying conditions.

[0012] It should be noted that the force frame mentioned in this article refers to the rigid support component arranged along the width of the mesh belt. Its core function is to bear the transport load and maintain the structural rigidity of the mesh belt. The spiral is a flexible component that connects adjacent force frames. It realizes the flexible extension of the mesh belt and the load distribution through the spiral shape. The horseshoe connecting plate is a key component for realizing the connection and limiting of the end of the force frame. Through the unique horseshoe-shaped contour design, it optimizes the stress distribution while ensuring the connection strength.

[0013] In one embodiment, the horseshoe-shaped connecting plate includes an upper crossbeam segment extending along the bandwidth direction, multiple bent leg segments extending downward from the upper crossbeam segment on the left and right sides, and a lower bridging segment located at the bottom through which the force bones pass, the three forming a horseshoe-shaped profile with the opening facing inward. This structure provides lateral support through the upper crossbeam segment, secures the force bones through the lower bridging segment, and the bent leg segments form an elastic buffer structure through a multi-segment bending design, effectively distributing end loads.

[0014] In one embodiment, the multi-segment bending leg section includes, from top to bottom, a narrowing transition section, an outward bulging buffer section, and a vertical guide section, with at least two bending points; the left and right multi-segment bending leg sections are mirror-symmetrical with respect to the longitudinal baseline of the inserted force frame. The narrowing transition section achieves gradual load transfer, the outward bulging buffer section provides elastic deformation space to absorb impact loads, the vertical guide section ensures accurate positioning during force frame insertion, and the mirror-symmetrical structure ensures the balance of forces on both sides, avoiding lateral deformation caused by uneven force distribution.

[0015] In one embodiment, the upper crossbeam segment is a straight segment or a large-radius arc segment; the vertical guide segment and the lower bridging segment are connected by a rounded corner or a bend to reduce stress concentration. The large-radius arc segment of the upper crossbeam segment can reduce the stress concentration area, while the rounded corner or bend transition design avoids the stress concentration problem caused by right-angle connections, thus improving the fatigue resistance of the connecting plate.

[0016] In one embodiment, the upper crossbeam section of the horseshoe-shaped connecting plate is provided with an adjustment hole, which is an elongated oval hole extending along the bandwidth direction, serving as an assembly adjustment structure. Preferably, the long axis of the elongated oval hole is arranged along the bandwidth direction to compensate for assembly tolerances and thermal deformation. The setting of the adjustment hole allows the rigid frame to produce a small displacement in the bandwidth direction, which can both accommodate the accumulation of tolerances during the assembly process and alleviate thermal expansion and contraction deformation caused by temperature changes, avoiding internal stress caused by rigid connections.

[0017] In one embodiment, the lower bridging section is provided with a fixing hole coaxial with the axis of the force frame. The fixing hole is a circular hole used as a fixing and positioning structure. The interference fit or clearance fit design between the fixing hole and the force frame ensures accurate positioning and reliable fixation between the connecting plate and the force frame, forming a stable force transmission path.

[0018] In one embodiment, the lower circular hole of each horseshoe-shaped connecting plate is inserted into a support frame, and the upper adjustment hole is inserted into an adjacent support frame located above it; multiple horseshoe-shaped connecting plates arranged side by side are symmetrically arranged about the axis of the support frames through which they are inserted. This cross-layer insertion method allows adjacent support frames to form a rigid connection unit through the connecting plates, and the symmetrical arrangement of the connecting plates ensures uniform transmission of loads on both sides, preventing skewing during the operation of the conveyor belt.

[0019] In one embodiment, the helical end is fixedly connected to the force frame in the end region adjacent to the horseshoe connecting plate, and the fixing method is at least one of welding, riveting, or mechanical locking; preferably, welding is used. The fixed connection between the helical end and the force frame ensures the effective transmission of the lateral load of the conveyor belt, and the welding connection method provides high-strength connection reliability and avoids loosening during high-speed operation.

[0020] In one embodiment, the upper crossbeam segments of the horseshoe-shaped connecting plates arranged side by side are parallel to each other, with their openings facing inwards to enhance the consistency of stress and lateral stability at the ends of both rows. The parallel upper crossbeam segments form a uniform load-bearing surface, and the design of the openings facing inwards to the rows allows the connecting plates to form a mutually supporting mechanical system when subjected to lateral forces, significantly improving the deformation resistance of both sides of the conveyor belt.

[0021] In one embodiment, the horseshoe-shaped connecting plate is formed by integral stamping of a metal sheet and multiple bending processes, with the edges deburred. The integral stamping process ensures the structural strength and dimensional accuracy of the connecting plate, the complex contour formed by multiple bending processes meets the mechanical design requirements, and the deburring process avoids stress concentration and wear problems caused by sharp edges, thereby improving the overall service life of the conveyor belt.

[0022] In one embodiment, the helix is ​​a left-handed helix, a right-handed helix, or a combination of left-handed and right-handed helices; preferably, adjacent rows along the conveying direction are alternately arranged with left-handed and right-handed helices. The alternation of left and right helices can balance the torque load during the operation of the conveyor belt, avoid the problem of conveyor belt deviation caused by a single helix direction, and improve the stability of the conveying system.

[0023] The beneficial effects of this utility model are as follows: This utility model proposes an auxiliary reinforcement horseshoe mesh belt structure, which includes multiple stiffeners spaced apart along the belt width direction, a spiral strut spanning between adjacent stiffeners, and horseshoe connecting plates that pass through and are fixed to the stiffeners for end bearing and limiting. At least two horseshoe connecting plates are arranged side by side on both sides of the spiral, i.e., at both ends of each stiffener. The lower end of the horseshoe connecting plate passes through one of the stiffeners, and the upper end passes through the stiffener located above and adjacent to the stiffener. By arranging at least two horseshoe connecting plates side by side at both ends of multiple stiffeners and staggering them between adjacent stiffeners, the directional connection strength and integrity of the mesh belt are significantly improved, and the ability to resist lateral deformation and torsion is effectively enhanced. This ensures that it can maintain stable operation under harsh conveying conditions of high speed and heavy load, and extends its service life. Attached Figure Description

[0034] The following embodiments are described to aid in understanding this application. These embodiments are not, and should not be, construed in any way as limiting the scope of protection of this application.

[0035] In the following description, those skilled in the art will recognize that throughout this discussion, components may be described as individual functional units (which may include subunits), but those skilled in the art will recognize that various components or portions thereof may be divided into individual components or may be integrated together (including integrated within a single system or component).

[0036] Furthermore, the connection between components or systems is not intended to be limited to a direct connection; on the contrary, data between these components may be modified, reformatted, or otherwise altered by intermediate components. Additionally, other or fewer connections may be used. It should also be noted that the terms "connection," "link," or "input" should be understood to include direct connections, indirect connections via one or more intermediate devices, and wireless connections. Example 1:

[0037] In existing technologies, traditional horseshoe-shaped conveyor belt structures suffer from insufficient longitudinal connection strength and are prone to lateral deformation under high linear speed conveying conditions, resulting in poor belt operation stability and short service life. For example, some conveyor belts use a single connecting plate structure, which experiences uneven stress at the ends during high-speed operation, causing the connecting plate to loosen and affecting overall conveying performance. To address these issues, this application proposes an auxiliary reinforcement horseshoe-shaped conveyor belt structure. By optimizing the layout and structural design of the connecting plates, the reliability of the conveyor belt in high-speed conveying scenarios is significantly improved.

[0038] like Figure 1 As shown, the horseshoe-shaped conveyor belt structure for auxiliary reinforcement proposed in this application includes multiple stiffeners 10 spaced apart along the belt width direction, a spiral 20 spanning between adjacent stiffeners 10, and horseshoe-shaped connecting plates 30 passing through and fixed to the stiffeners 10 for end bearing and limiting. At least two horseshoe-shaped connecting plates 30 are arranged side-by-side on both sides of the spiral 20, i.e., at both ends of each stiffener 10. The lower end of each horseshoe-shaped connecting plate 30 passes through one of the stiffeners 10, and the upper end passes through an adjacent stiffener 10 located above it. The side-by-side horseshoe-shaped connecting plates 30 have through holes at both the top and bottom for the stiffeners 10 to pass through. This structural design effectively improves the longitudinal connection strength and resistance to lateral deformation under high linear speed conveying conditions.

[0039] Specifically, such as Figure 3 As shown, the horseshoe-shaped connecting plate 30 includes an upper crossbeam segment 31 extending along the bandwidth, left and right multi-segment bent leg segments 32 extending downward from the upper crossbeam segment 31, and a lower bridging segment 33 located at the bottom through which the force rib 10 passes. These three segments form a horseshoe-shaped profile with the opening facing inwards. The multi-segment bent leg segments 32, from top to bottom, include a narrowing transition segment 321, an outward bulging buffer segment 322, and a vertical guide segment 323, with at least two bending points. The left and right multi-segment bent leg segments 32 are mirror-symmetrical with respect to the longitudinal baseline through which the force rib 10 passes. This bending structure design achieves a smooth force transition through the narrowing transition segment 321, provides elastic buffer space through the outward bulging buffer segment 322, and ensures the accuracy of the force rib 10's insertion through the vertical guide segment 323, thereby enhancing the structural strength and buffering performance of the connecting plate.

[0040] Compared to existing technologies, traditional connecting plate bending legs are mostly single straight sections or simple bends, lacking segmented structures, resulting in uneven force transmission and poor buffering capacity. For example, traditional leg sections lack a tapering transition design, easily causing stress concentration during sudden load changes; without an outer bulge buffer section 322, they cannot absorb vibration energy during high-speed operation, leading to fatigue damage to the connecting plate. This application forms a segmented structure through at least two bending points, utilizing a mirror-symmetric layout to achieve smooth force transition and vibration buffering.

[0041] The upper crossbeam segment 31 can be a straight segment or a large-radius arc segment. The vertical guide segment 323 and the lower bridge segment 33 are connected by a rounded corner or a bend to reduce stress concentration and prevent the connecting plate from breaking due to stress concentration during high-speed operation.

[0042] like Figure 2 As shown, the upper crossbeam section 31 of the horseshoe connecting plate 30 is provided with an adjustment hole 311, which is an elongated oval hole extending along the width direction. It serves as an assembly adjustment structure, facilitating the adjustment of the relative position of the connecting plate and the support frame 10 according to actual working conditions during installation, thereby improving assembly flexibility. The lower bridging section 33 is provided with a fixing hole 331 coaxial with the axis of the support frame 10. The fixing hole 331 is a round hole, which serves as a fixing and positioning structure to ensure the positional accuracy of the support frame 10 after it is installed, and to prevent displacement during operation.

[0043] Each horseshoe-shaped connecting plate 30 has a lower circular hole that passes through a support rib 10, and an upper adjustment hole 311 that passes through an adjacent support rib 10 located above it. Multiple horseshoe-shaped connecting plates 30 arranged side-by-side are symmetrically positioned about the axis of the support ribs 10 through which they pass. This symmetrical layout ensures even force distribution on both sides of the conveyor belt, further enhancing lateral stability. The end of the spiral 20 is fixedly connected to the support rib 10 in the end region adjacent to the horseshoe-shaped connecting plate 30. The fixing method is at least one of welding, riveting, or mechanical locking, ensuring reliable connection between the spiral and the support rib 10 and preventing loosening during high-speed operation.

[0044] The upper crossbeam sections 31 of the horseshoe connecting plates 30 arranged side by side are parallel to each other, and their openings all face inwards to enhance the consistency of force and lateral stability at the ends of the two rows. The helix 20 can be a left helix 21, a right helix 22, or a combination of the left helix 21 and the right helix 22. Different helix combinations can adapt to the needs of different conveying conditions and improve the flexibility and adaptability of the mesh belt operation.

[0045] Through the above technical solution, this application improves the reliability of the horseshoe-shaped mesh belt structure under high linear speed conveying conditions, solves the problems of insufficient connection strength and easy deformation in existing structures, and provides a better mesh belt solution for the industrial conveying field. The distributed connection plate layout and refined structural design not only enhance the mechanical properties of the mesh belt, but also improve the convenience of assembly and maintenance, and have significant practical value and market application prospects.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
