Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of circulating conveying equipment, specifically relating to horizontal circulating conveying mechanisms, systems and devices. Background Technology
[0002] Current circulating conveyor systems include circulating lifting conveyor systems and automated parking system circulating systems. Circulating lifting conveyor systems employ a mirror-symmetrical layout of the feeding and discharging lifting mechanisms, using three sets of chains to drive the roller trays synchronously, achieving continuous material transport, reducing floor space, and improving production line efficiency. Automated parking system circulating systems use lifting guides, centrifugal safety locks, and fixed steel wire ropes to achieve multi-point locking of the lifting platform during vertical circulation, preventing accidental falls, and are suitable for high-density parking lots. Both circulating lifting conveyor systems and automated parking system circulating systems are vertical circulating conveyor systems, suitable for applications with limited floor space and high work heights. However, vertical circulating conveyor systems suffer from a higher center of gravity, higher structural strength requirements, and higher manufacturing costs. For applications with limited floor space and where factory or work height cannot be too high, horizontal circulating conveyor systems are required. Currently, no horizontal circulating conveyor system designs have been found, therefore, there is an urgent need to provide such a system. Utility Model Content

[0004] To achieve the above-mentioned objectives, this application discloses a horizontal circulating conveying mechanism, including a conveying chain and a mounting plate. The two ends of the conveying chain are respectively sleeved on a driving sprocket and a driven sprocket. A main support plate and a secondary support plate are respectively provided on the sides of the driving sprocket and the driven sprocket. The main support plate and the secondary support plate are respectively mounted on the driving shaft and the driven shaft. The mounting plate is provided on the conveying chain, and a bearing member adapted to the upper and lower edges of the main support plate and the secondary support plate is provided at the lower part of the mounting plate.
[0005] Preferably, it includes two sets of conveyor chains, which are symmetrically arranged, and a hanging shaft is provided between the two sets of conveyor chains. The two ends of the hanging shaft are respectively connected to the upper part of the hanging plate on the two sets of conveyor chains.
[0006] Preferably, the conveyor chain is provided with a plurality of mounting plates at intervals.
[0007] Preferably, each set of conveyor chain horizontal sections is provided with a chain track at the lower end, and the chain track is adapted to the conveyor chain horizontal section.
[0008] Preferably, each set of conveyor chain horizontal sections is provided with a chain pressure rail at the upper end, and the chain pressure rail is adapted to the conveyor chain horizontal section.
[0009] Accordingly, this application also discloses a horizontal circulating conveying system, including a material platform and two sets of symmetrically arranged conveying chains. Each set of conveying chains has its two ends respectively fitted onto a driving sprocket and a driven sprocket. A main support plate and a driven support plate are respectively arranged beside the driving sprocket and the driven sprocket. The main support plate and the driven support plate are respectively arranged on the driving shaft and the driven shaft. Multiple hanging plates are arranged at intervals on each set of conveying chains. The lower part of the hanging plate is provided with a bearing member adapted to the upper and lower edges of the main support plate and the driven support plate. A hanging shaft adapted to the suspension part of the material platform is arranged between the two sets of conveying chains. The two ends of the hanging shaft are respectively connected to the upper part of the hanging plates on the two sets of conveying chains. The axis of the hanging shaft is perpendicular to the conveying direction of the conveying chain.
[0010] Preferably, each set of conveyor chain horizontal sections is provided with a chain track at the lower end, the chain track being adapted to the conveyor chain horizontal section; each set of conveyor chain horizontal sections is provided with a chain pressure rail at the upper end, the chain pressure rail being adapted to the conveyor chain horizontal section.
[0011] Preferably, the top of the material platform is symmetrically provided with two suspension parts, and the circumferential sidewall of the hanging shaft is provided with two limiting parts, the distance between the outer sidewalls of the two limiting parts is equal to the distance between the inner sidewalls of the two suspension parts.
[0012] Preferably, a lifting platform is provided below the conveyor chain for loading and unloading materials.
[0013] Accordingly, this application also discloses a horizontal circulating conveying and processing device, including one of a drying chamber, a storage chamber, and a freezing chamber, wherein the above-mentioned circulating conveying system is provided in the drying chamber, storage chamber, or freezing chamber.
[0014] This utility model has the following beneficial effects:
[0015] 1. By setting a mounting plate on the conveyor chain, and setting a main support plate and a driven support plate next to the drive sprocket and driven sprocket, the main support plate and driven support plate are set on the periphery of the drive shaft and driven shaft through bearings. The lower part of the mounting plate is set with a bearing component that matches the upper and lower edges of the main support plate and driven support plate. When the mounting plate moves near the drive sprocket and driven sprocket, the conveyor chain will move violently due to the polygon effect and the gravity of the material. By setting the main support plate and driven support plate on the periphery of the drive shaft and driven shaft, the polygon effect of the conveyor chain can be effectively prevented, ensuring smooth operation and preventing up and down fluctuations due to polygon and load.
[0016] 2. Compared to vertical circulating conveyor systems, horizontal circulating conveyor systems have a lower center of gravity, lower strength requirements, and lower manufacturing costs. The conveyor chain drives the hanging shafts to automatically load / unload materials onto the platform, achieving material circulation within the system. It features a compact and reliable structure with high space utilization, making it widely applicable in systems requiring cyclic processing and conveying, such as circulating drying, circulating storage, and circulating freezing. Specifically, the horizontal circulating conveyor system can be placed inside drying chambers, storage chambers, or freezing chambers. The hanging plates on the conveyor chain play a significant role in the conveying process, reducing the size of the conveyor sprockets and lowering costs.
[0017] 3. By setting chain pressure rails and chain tracks on the upper and lower sides of the conveyor chain respectively, even if the material platform and the material have a certain weight, the upper and lower layers of the conveyor chain have support structures, which can effectively prevent the chain from sagging in the horizontal direction, while ensuring that the material platform moves in the horizontal direction.

Detailed Implementation
[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.
[0026] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] It should be noted that, Figure 1-3 The worktable of the middle conveyor chain 1 is not shown. Figure 3 Only one set of conveyor chains 1 is shown, including the chain track 7 and the chain pressure rail 6.
[0028] like Figure 1-5 As shown, this application discloses a horizontal circulating conveying mechanism, including a conveying chain 1 and mounting plates 9. One or more mounting plates 9 are provided on the conveying chain 1. The mounting plates 9 are used to hang the materials to be conveyed. The materials to be conveyed can be placed on a material platform 10, and the material platform 10 can be detachably mounted on the mounting plates 9. The two ends of the conveying chain 1 are respectively sleeved on a driving sprocket 2 and a driven sprocket 3. A motor drives the driving sprocket 2 to rotate, which in turn drives the driven sprocket 3 to rotate under the action of the conveying chain 1. A main support plate 4 and a driven support plate 5 are respectively provided on the side of the wheel 3. The main support plate 4 and the driven support plate 5 are respectively sleeved on the outer periphery of the drive shaft and the driven shaft. The lower part of the mounting plate 9 is provided with a bearing member 8 that is adapted to the upper and lower edges 16 of the main support plate 4 and the driven support plate 5. When the mounting plate 9 moves to the vicinity of the drive sprocket 2 and the driven sprocket 3, the bearing member 8 at the lower part of the mounting plate 9 can contact the upper and lower edges 16 of the main support plate 4 and the driven support plate 5 to prevent the conveyor chain 1 from shaking violently and can effectively prevent the polygonal effect of the conveyor chain 1.
[0029] The carrier 8 can be implemented in various ways, such as as a roller, bearing, or traveling wheel. The carrier 8 is rotatably connected to the lower part of the mounting plate 9. When the carrier 8 contacts the upper and lower edges 16 of the main support plate 4 and the secondary support plate 5, rolling friction occurs between the carrier 8 and the upper and lower edges 16 of the main support plate 4 and the secondary support plate 5. The shape of the mounting plate 9 is not strictly defined and can be triangular, quadrilateral, frustum-shaped, etc. In a preferred embodiment, to improve the stability of the mounting plate 9, it can be made narrow at the top and wide at the bottom. When the mounting plate 9 moves to the arc position of the conveyor chain 1, there is a transmission ratio between the mounting plate 9 and the sprocket, which ensures that the material platform 10 will not collide.
[0030] In a further embodiment, when the material platform 10 is large and the material to be conveyed is heavy, the horizontal circulating conveying mechanism includes two sets of conveying chains 1. The two sets of conveying chains 1 are symmetrically arranged in the horizontal direction, and a hanging shaft 15 is provided between the two sets of conveying chains 1. The two ends of the hanging shaft 15 are respectively connected to the upper part of the hanging plate 9 on the two sets of conveying chains 1. The axial direction of the hanging shaft 15 is perpendicular to the conveying direction of the conveying chain 1. The material platform 10, on which the material to be conveyed is placed, is suspended on the hanging shaft 15. The material platform 10 and the hanging shaft 15 are detachably connected, which facilitates easy loading and unloading by the staff.
[0031] In a preferred embodiment, multiple mounting plates 9 are evenly spaced on the two sets of conveyor chains 1, and multiple hanging shafts 15 are arranged between the two sets of conveyor chains 1, which can simultaneously convey multiple batches of materials and improve the utilization rate of the equipment.
[0032] In a further embodiment, a chain track 7 is provided at the lower end of the horizontal section of each set of conveyor chains 1, and the chain track 7 is adapted to the horizontal section of the conveyor chain 1. A chain pressure rail 6 is provided at the upper end of the horizontal section of each set of conveyor chains 1, and the chain pressure rail 6 is adapted to the horizontal section of the conveyor chain 1. The chain track 7 and the chain pressure rail 6 correspond to each other, and the space formed between them allows the conveyor chain 1 to move, and restricts the conveyor chain 1 to always remain horizontal during movement, unaffected by the weight of the material platform 10.
[0033] Specifically, since chain pressure rails 6 and chain tracks 7 are respectively set on the upper and lower sides of the conveyor chain 1, the mounting plate 9 is fixedly set on one side wall of the conveyor chain 1, and the bearing member 8 is installed on the side wall of the mounting plate 9 facing away from the conveyor chain 1 and near the bottom of the mounting plate 9, so that the bearing member 8, the mounting plate 9, the conveyor chain 1, the chain pressure rails 6 and the chain tracks 7 do not interfere with each other.
[0034] like Figure 1-6 As shown, this application also discloses a horizontal circulating conveying system, including a material platform 10 and two sets of symmetrically arranged conveying chains 1. Each set of conveying chains 1 has its two ends respectively fitted onto a driving sprocket 2 and a driven sprocket 3. A main support plate 4 and a driven support plate 5 are respectively arranged on the sides of the driving sprocket 2 and the driven sprocket 3. The main support plate 4 and the driven support plate 5 are respectively arranged on the driving shaft and the driven shaft. Multiple hanging plates 9 are arranged at intervals on each set of conveying chains 1. The lower part of the hanging plate 9 is provided with a bearing member 8 adapted to the upper and lower edges 16 of the main support plate 4 and the driven support plate 5. A hanging shaft 15 adapted to the suspension part 11 of the material platform 10 is arranged between the two sets of conveying chains 1. The two ends of the hanging shaft 15 are respectively connected to the upper part of the hanging plates 9 on the two sets of conveying chains 1. The axial direction of the hanging shaft 15 is perpendicular to the conveying direction of the conveying chain 1.
[0035] The material platform 10, on which the materials to be conveyed are placed, is suspended on the hanging shaft 15. The material platform 10 and the hanging shaft 15 are detachably connected, facilitating easy loading and unloading by workers. This allows for the simultaneous conveying of multiple batches of materials, improving equipment utilization. The structure of the bearing component 8 and the mounting plate 9, as well as the installation structure between the bearing component 8 and the mounting plate 9, are the same as described above (design of a horizontal circulating conveyor mechanism). When the mounting plate 9 moves to the arc position of the conveyor chain 1, there is a transmission ratio between the mounting plate 9 and the sprocket, ensuring that the material platform 10 will not collide.
[0036] In a further embodiment, a chain track 7 is provided at the lower end of the horizontal section of each set of conveyor chains 1, and the chain track 7 is adapted to the horizontal section of the conveyor chain 1. A chain pressure rail 6 is provided at the upper end of the horizontal section of each set of conveyor chains 1, and the chain pressure rail 6 is adapted to the horizontal section of the conveyor chain 1. The chain track 7 and the chain pressure rail 6 correspond to each other, and the space formed between them allows the conveyor chain 1 to move, and restricts the conveyor chain 1 to always remain horizontal during movement, unaffected by the weight of the material platform 10.
[0037] In a further embodiment, the top of the material platform 10 is provided with one or more suspension parts 11, each suspension part 11 having an arc-shaped hole adapted to the hanging shaft 15. The suspension part 11 can take the form of a hook, a ring buckle, a U-shaped hanging ring, or other embodiments.
[0038] In a preferred embodiment, two suspension parts 11 are symmetrically arranged on the top of the material platform 10. Each suspension part 11 preferably has a hook. Two limiting parts 13 are provided on the circumferential sidewall of the hanging shaft 15. The distance between the outer walls of the two limiting parts 13 (the sides of the limiting parts 13 facing away from each other) is equal to the distance between the inner walls of the two suspension parts 11 (the sides of the suspension parts 11 facing each other). By setting the limiting parts 13, the position between the two suspension parts 11 is restricted, preventing the two suspension parts 11 from sliding back and forth along the axial direction of the hanging shaft 15. The limiting parts 13 can be an annular block, a square block, or a polygonal block arranged around the hanging shaft 15. Alternatively, as... Figure 1-3 As shown, a sleeve rod 14 is fixedly installed on the outside of the hanging shaft 15. The diameter of the outer circle of the sleeve rod 14 is larger than the diameter of the hanging shaft 15. The length of the sleeve rod 14 is equal to the distance between the inner side walls of the two suspension parts 11. At this time, the end of the sleeve rod 14 has a limiting function, and the end of the sleeve rod 14 is the limiting part 13.
[0039] In a further embodiment, a lifting platform 12 is provided below the conveyor chain 1 for loading and unloading materials.
[0040] Working principle of horizontal circulating conveyor mechanism and system: Figure 1Taking this as an example, the motor drives the drive sprocket 2 to rotate, and the conveyor chain 1 can move clockwise and counterclockwise inside the conveying system under the drive of the drive sprocket 2. The hanging plate 9 moves with the conveyor chain 1, thereby causing the material platform 10 to move with the conveyor chain 1, realizing horizontal circulating conveying.
[0041] Feeding: The drive sprocket 2 moves clockwise, driving the conveyor chain 1 to move clockwise within the system. The material platform 10 is raised to a suitable position by the lifting platform 12. The hanging shaft 15 on the hanging plate 9 on the moving conveyor chain 1 hangs the material platform 10 on the lifting platform 12 through the hook, driving the material platform 10 to circulate within the system.
[0042] Unloading: The drive sprocket 2 moves counterclockwise, driving the conveyor chain 1 to move counterclockwise within the system, raising the lifting platform 12 to a suitable position. When the material table 10 moves counterclockwise under the drive of the hanging shaft 15 to the bottom of the material table 10 and contact the lifting platform 12, the hook of the hanging shaft 15 and the material table 10 are successfully disengaged.
[0043] In addition to the above-mentioned working mode, the horizontal circulating conveying system of this application can also work in the following way: whether it is loading or unloading, the drive sprocket 2 always maintains clockwise motion or always maintains counterclockwise motion.
[0044] The horizontal circulating conveyor system disclosed in this application uses a lifting platform 12 for loading / unloading, and two sets of conveyor chains 1 are symmetrically arranged. The conveyor chains 1 drive the hanging shafts 15 on them to automatically load / unload the material platform 10, realizing the circulating conveying of materials within the system. It has a compact and reliable structure, high space utilization, and can be widely used in systems requiring circulating processing and conveying, such as circulating drying, circulating storage, and circulating freezing. Specifically, the horizontal circulating conveyor system is placed inside a drying chamber, storage chamber, or freezing chamber, and the materials to be dried or frozen circulate within the chamber, ensuring uniform drying and freezing, and dynamic heating and cooling. The hanging plate 9 on the conveyor chain 1 plays a significant role in the conveying process. It can reduce the size of the conveyor sprocket, lowering costs. Simultaneously, in the arc-shaped section of the conveyor chain 1, it has a transmission ratio i with the conveyor sprocket, effectively preventing collisions between the horizontally moving material platform 10 and the arc-shaped moving material platform 10. The magnitude of the transmission ratio i is related to the sprocket size, load, and platform size, and is a variable value.
[0045] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
