Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, and more specifically, to a horseshoe-shaped conveyor belt that can transport multiple materials in parallel. Background Technology

[0002] As a conveyor for frozen products, refrigerated conveyor belts are typically installed by winding them onto the hubs of refrigeration equipment within a cold storage facility. As the hub rotates, the belt moves upwards to freeze the items. Its standard structure consists of parallel reinforcing ribs, alternating left-hand and right-hand spirals wound between the ribs, and horseshoe-shaped connecting plates that connect the two ends of the ribs and close the force transmission path. This weaving method gives the conveyor belt excellent longitudinal flexibility to bypass sprockets, as well as good lateral rigidity and planar load-bearing capacity, meeting the needs of continuous high-volume production.

[0003] However, in the actual production of frozen foods, there is often a need to process multiple different types, specifications, or batches of products (such as dumplings with different fillings, shrimp of different sizes, and chicken nuggets of different flavors) on the same freezing or cooling line. If traditional unseparated conveyor belts are used, different materials are easily subject to lateral rolling, sliding, or splashing due to vibration and inertia during dynamic transport, leading to material mixing and cross-contamination, affecting product quality and safety. Furthermore, the finished product sorting process also faces significant challenges, increasing labor costs and losses.

[0004] Currently, the industry mainly uses two methods to achieve separate conveying: one is to install multiple independent conveyor lines in parallel, but this method requires large equipment footprint, high cost, high energy consumption, and complex operation and maintenance; the other is to install fixed partitions on the mesh belt, but this method is difficult to adapt to the contraction and bending of the mesh belt during dynamic operation, which can easily lead to stress concentration and component damage.

[0005] In view of this, the present invention proposes a horseshoe-shaped conveyor belt with a stable structure, suitable for materials of multiple specifications, and capable of transporting multiple materials simultaneously. Utility Model Content

[0006] The purpose of this application is to provide a horseshoe-shaped conveyor belt that can transport multiple materials simultaneously. By setting multiple upright baffles at intervals along the conveying direction in either the row containing the left spiral or the row containing the right spiral, multiple materials can be transported simultaneously, smoothly and efficiently.

[0007] A horseshoe-shaped conveyor belt capable of transporting multiple materials simultaneously includes:

[0008] Multiple reinforcing ribs spaced apart along the width of the mesh belt;

[0009] The left and right spirals are alternately wound between adjacent force bones;

[0010] And the horseshoe-shaped connecting plates set at both ends of each force frame;

[0011] In the spiral row formed between two adjacent force bones, multiple upright baffles are provided only in either the row containing the left spiral or the row containing the right spiral, arranged at intervals along the conveying direction, so as to separate the left spiral or the right spiral of the row into at least two parallel transport areas.

[0012] Each of the upright baffles is provided with a round hole and a waist-shaped hole. One of the two adjacent force bars is fixedly connected to the upright baffle through the round hole, and the other bar passes through the waist-shaped hole and forms a sliding fit with it, so as to realize the avoidance and stroke compensation during the tensioning and contraction of the mesh belt, and to restrict the lateral movement of the material through the upright baffle.

[0013] It is important to note that the reinforcing members discussed in this article are the main load-bearing components of the conveyor belt. They are made of stainless steel or corrosion-resistant high-strength steel and are spaced apart along the width to provide structural support. The left and right spirals are elastic metal wires that are alternately wound to form a material-bearing surface. Their elastic deformation capability, combined with the reinforcing members, enables tension adjustment. The horseshoe connecting plate spans both ends of the reinforcing members, not only stabilizing the ends of the spirals but also forming a closed tension loop, ensuring uniform tension distribution during conveyor belt operation. The core function of the upright baffle is to divide a single spiral line into multiple independent transport areas. Its combination of round and oblong holes overcomes the stress limitations of traditional fixed connection structures during thermal expansion and contraction or tension adjustment, achieving dynamic compensation through sliding fit.

[0014] By constructing an innovative architecture of single-row baffle separation and elastic compensation connection, this application achieves a dual breakthrough in parallel multi-material conveying and structural adaptive adjustment. Specifically, the upright baffles are selectively set in either the left or right spiral row, dividing a single conveying channel into at least two independent transport areas. Each area can simultaneously convey materials of different specifications and shapes, overcoming the limitation of traditional mesh belts that can only convey single materials. The connection method of fixing the support frame with a circular hole and sliding the waist-shaped hole between the support frame and the upright baffle allows the support frame to be rigidly positioned with the baffle through the circular hole when the mesh belt is tensioned. When there is thermal expansion and contraction or changes in tension stroke, the other support frame can slide along the waist-shaped hole, driving the spiral to follow, avoiding structural deformation or stress concentration caused by rigid connection. This design not only ensures the lateral constraint accuracy of the baffle on the material during transportation, but also gives the mesh belt adaptive compensation capability, overcoming the problem of insufficient conveying adaptability caused by the structural rigidity of traditional mesh belts.

[0015] In one embodiment, the left and right spirals are staggered and continuously arranged between rows along the conveying direction; the left or right spiral located in the row where the upright baffle is located and the spirals in the adjacent rows above and below are respectively constrained at the end and the force transmission closure is achieved through adjacent force bones and horseshoe connecting plates.

[0016] By continuously arranging the spirals in a staggered pattern, a three-dimensional force transmission network is formed. This allows the force on the spirals in the row containing the baffles to be quickly transmitted to the entire conveyor belt structure through the force frame and the horseshoe-shaped connecting plate, avoiding localized stress concentration. Specifically, when material acts on the transport area separated by the baffles, the lateral force on the spirals is transmitted to the horseshoe-shaped connecting plate through the force frame, forming a closed force transmission path and ensuring balanced force distribution across the entire conveyor belt. This arrangement not only ensures the structural strength of the row containing the baffles but also improves the stability of the conveyor belt during operation through the synergistic effect of adjacent rows of spirals, solving the problem of insufficient local stiffness caused by traditional single-row baffle installations.

[0017] In one embodiment, multiple upright baffles are arranged at equal intervals or predetermined pitches along the conveying direction; the transverse width of the transport area enclosed by adjacent upright baffles and the left or right spiral of the row is consistent or varies according to a preset rule to adapt to the parallel conveying of materials of different specifications.

[0018] The flexible design of baffle spacing and transport area width enables modular material adaptation. Equal-distance layout is suitable for batch conveying materials of uniform specifications, while predetermined pitch layout can be adjusted according to material size variations. For example, a wider area can be set at the beginning of the conveyor line to convey large-sized materials, while the spacing can be reduced at the end to convey smaller-sized materials. The consistent lateral width of the transport area facilitates the positioning and sorting of standardized materials, while the progressive design allows for dynamic size adjustments of materials during transport, such as directional arrangement of round materials through gradually narrowing areas. This design breaks through the limitations of fixed areas in traditional mesh belt conveyors, allowing the same mesh belt to flexibly adapt to the conveying needs of various materials, significantly improving the equipment's versatility.

[0019] In one embodiment, the circular hole is used to fix and weld to one of the two adjacent force bones for positioning; the waist-shaped hole is arranged along the conveying direction to compensate for thermal expansion and contraction and tension stroke, and the relative displacement of the other force bone passing through it is used to drive the left and right spirals connected to it to follow.

[0020] In one embodiment, to avoid interference with the left or right spiral and horseshoe connecting plate on the side without baffles, a limiting gap is reserved between the row where the upright baffle is located and the adjacent row. When the mesh belt shrinks, the force rib with waist-shaped holes forms a forward feeding clearance trajectory relative to the upright baffle along the conveying direction.

[0021] Furthermore, the upright baffle is a plate-shaped or integrally formed bent rib structure, with its lower edge tangent to or in a clearance fit with the left or right spiral of the row, and its upper edge maintaining a safe clearance with the material during operation to limit the lateral rolling of the material and reduce wear.

[0022] In one embodiment, the upright baffle and the support frame positioned by the circular hole are connected by at least one of welding, riveting, or snap-fitting; the other support frame with the waist-shaped hole is in a sliding fit with the waist-shaped hole.

[0023] In one embodiment, horseshoe connecting plates are respectively disposed at both ends of each force bone and bridging adjacent force bones, for stabilizing the connection between the ends of the left helix and the right helix and forming a tension closed loop.

[0024] In one embodiment, the force frame, upright baffle, and horseshoe connecting plate are made of stainless steel or corrosion-resistant high-strength steel; the left and right spirals are made of elastic metal wire.

[0025] The beneficial effects of this utility model are as follows: This utility model proposes a horseshoe-shaped conveyor belt capable of transporting multiple materials simultaneously, including a support frame, a left spiral, a right spiral, a horseshoe connecting plate, and upright baffles. By setting upright baffles in a single row between adjacent support frames, such as a row of left spirals or a row of right spirals, the conveying surface is divided into multiple independent channels, realizing the function of simultaneously conveying multiple materials on a single conveyor belt. This greatly improves space utilization and conveying efficiency, and avoids the equipment cost and energy consumption problems caused by multiple parallel conveyor lines. The upright baffles are fixedly connected to and slidably engaged with adjacent support frames through round holes and oblong holes, respectively. They can automatically compensate for stroke changes when the conveyor belt is tensioned, contracted, or thermally expanded and contracted, effectively avoiding problems such as stress concentration, structural interference, or baffle detachment, and significantly improving the reliability and lifespan of the conveyor belt in frozen environments.

[0036] The following embodiments are described to aid in understanding this application. These embodiments are not, and should not be construed as, limiting the scope of protection of this application.

[0037] 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).

[0038] 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:

[0039] While existing conveyor belt structures possess flexibility and tensile strength, the lack of internal separation mechanisms makes them prone to lateral rolling, mixing, or cross-contamination of different materials during transport. This affects finished product quality and increases sorting difficulty and labor costs. To address these shortcomings, this invention achieves anti-slip conveying capability without the need for additional baffles through optimized structural design.

[0040] like Figure 1-3 As shown, this embodiment provides a horseshoe-shaped conveyor belt capable of transporting multiple materials simultaneously. It includes multiple reinforcing members 10 spaced apart along the width of the conveyor belt, a left spiral 20 and a right spiral 30 alternately wound between adjacent reinforcing members 10, horseshoe connecting plates 40 disposed at both ends of the reinforcing members 10, and multiple upright baffles 50 disposed in the row of the left spiral 20 or the row of the right spiral 30. The multiple upright baffles 50 are spaced apart along the conveying direction to divide the spiral of the row into at least two parallel transport areas, thereby realizing the synchronous transport of materials of multiple specifications.

[0041] Compared with existing technologies, traditional mesh belts cannot effectively limit and classify materials for transport. Materials are prone to lateral rolling or stacking misalignment during transport. In this embodiment, by setting an upright baffle 50 on one side to physically separate the material channels, multiple channels can be transported in parallel, which improves the loading efficiency and adaptability of the conveying system.

[0042] like Figure 4As shown, the upright baffle 50 is provided with a round hole 51 and an oblong hole 52, which are used to fix and connect to one of the two adjacent force bars 10, respectively, and to slide and engage with the other. Specifically, the round hole 51 achieves a rigid connection, and the oblong hole 52 is arranged along the conveying direction to form a sliding compensation channel to adapt to the dimensional changes caused by the tensioning and contraction of the mesh belt.

[0043] Compared with existing technologies, the rigid fixed structure of traditional mesh belts is difficult to cope with changes in shrinkage stroke, and is prone to stress concentration or fatigue fracture. This application adopts a combination connection method of one fixed and one sliding, which enables the structure to maintain rigidity while having a certain degree of elasticity. The clearance compensation significantly improves the service life and system stability.

[0044] The left spiral 20 and the right spiral 30 are continuously and interspersed between each row along the conveying direction; the left spiral 20 or the right spiral 30 located in the row where the upright baffle 50 is located and the spirals of the adjacent rows above and below are respectively constrained at the end and the force transmission is closed through the adjacent force frame 10 and the horseshoe connecting plate 40, so as to realize the tension closed loop and structural self-locking of each transport section.

[0045] Compared with existing technologies, conventional spiral conveyor belts are prone to breaking the continuity of tension transmission after the installation of the partition structure, resulting in local loosening or swaying. This application maintains the rigidity and flexibility of the entire conveyor belt by staggering the arrangement and matching the connecting plates, so that the force transmission path between the spirals is logically closed, and the conveying stability is significantly improved.

[0046] Multiple upright baffles 50 are arranged at equal intervals or predetermined pitches along the conveying direction; the transverse width of the transport area enclosed by adjacent upright baffles 50 and the left spiral 20 or right spiral 30 of the same row is consistent or varies according to a preset rule to adapt to the parallel conveying of materials of different specifications.

[0047] Compared to existing technologies, traditional conveyor belts have fixed transport areas and channels, making them difficult to accommodate materials of various sizes. This application, through its adjustable spacing and gradual separation design, enables the conveyor belt to achieve versatility and compatibility with different types of products, making it suitable for simultaneous operation of multiple batches of irregularly shaped products.

[0048] The round hole 51 is used to fix it to the force frame 10 by welding or equivalent means. The long axis of the waist-shaped hole 52 is arranged along the conveying direction, so that the sliding force frame 10 can be adjusted by micro-displacement during the tensioning stage of operation, which drives the extension and contraction response of the connected spiral.

[0049] Compared with existing technologies, traditional welded rigid structures are prone to failure or damage to the connection points under temperature changes. This application introduces a sliding tolerance structure, which uses a waist-shaped hole to form a natural buffer for thermal expansion and contraction and dynamic loads, effectively reducing structural damage and maintenance frequency.

[0050] To prevent structural interference between the upright baffle 50 and the spiral or horseshoe connecting plate 40 on the side without a baffle, a gap is provided between the row containing the upright baffle 50 and its adjacent rows. When the conveyor belt contracts, the force ribs 10 with waist-shaped holes can be moved forward along the conveying direction to avoid spatial interference.

[0051] Compared with existing technologies, existing structures are prone to structural conflicts or jamming under thermal shrinkage or rapid loading in asymmetrical arrangements. This embodiment avoids such problems by pre-setting clearance trajectories and limiting gap layout, making the operation smoother and the failure rate lower.

[0052] The upright baffle 50 can be a plate-shaped or rib-shaped integral structure. Its lower edge is tangent to the adjacent spiral or maintains a limited clearance fit. During operation, the upper edge maintains a safe gap with the material, effectively preventing the material from falling off laterally and reducing structural wear.

[0053] Compared with existing technologies, traditional baffle designs either fail due to insufficient height or cause material scraping due to excessive height. This application, while ensuring the limiting function, avoids wear and debris accumulation through reasonable gap design, thus achieving structural stability in high-frequency use scenarios.

[0054] The connection between the baffle 50 and the rib 10 aligned with the circular hole can be welding, riveting, or snap-fitting, adapting to different manufacturing and maintenance requirements. The slotted hole 52 that mates with it forms a sliding fit connection with another rib 10, achieving reliable positioning and dynamic adjustment of the structure.

[0055] Compared with existing technologies, traditional integrated welded structures are not conducive to later replacement or component maintenance. This application improves the modularity and ease of maintenance of equipment through a combination of detachable and sliding structures, which is particularly suitable for high-frequency replacement scenarios in mass customization and industrialized production lines.

[0056] Horseshoe connecting plates 40 are respectively straddled at both ends of each force frame 10, connecting the ends of the left spiral 20 and the right spiral 30, forming a complete tension closed loop, so that the tension distribution is uniform and the transmission is continuous during the operation of the mesh belt.

[0057] Compared with existing technologies, some existing conveyor belts are only fixedly connected by welding at the ends, resulting in concentrated stress. This application adopts a multi-point closed structure and distributes the force through the horseshoe connecting plate 40, achieving low fatigue and high stability continuous operation capability.

[0058] The materials selected for each structural component are as follows: the stiffener 10, the upright baffle 50 and the horseshoe connecting plate 40 are made of stainless steel or corrosion-resistant high-strength steel to ensure high strength and corrosion resistance; the left spiral 20 and the right spiral 30 are made of elastic metal wire to balance the requirements of rigidity and flexibility.

[0059] Compared with existing technologies, conventional conveyor belts are prone to failure in high temperature, high humidity or strong corrosive environments. This application, through differentiated material selection and structural adaptation design, can still operate stably in extreme environments and meet the needs of various material processing scenarios such as freezing, hot drying, and pickling.

[0060] Through the above technical solution, this application divides the conveying surface into multiple independent channels by setting an upright baffle 50 in a single row between adjacent force frames 10, such as 20 rows of left spirals or 30 rows of right spirals. This enables a single mesh belt to simultaneously convey multiple materials, greatly improving space utilization and conveying efficiency, and avoiding the equipment cost and energy consumption problems caused by multiple parallel conveying lines. The upright baffle 50 is fixedly connected to and slidably engaged with adjacent force frames 10 through round holes 51 and oblong holes 52, respectively. It can automatically compensate for stroke changes when the mesh belt is tensioned, contracted, or thermally expanded and contracted, effectively avoiding problems such as stress concentration, structural interference, or baffle detachment, and significantly improving the reliability and lifespan of the mesh belt in freezing environments.

[0061] 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.
