Description

Technical Field

[0001] This invention relates to the field of plate chain conveying technology, specifically to a plate chain conveying line system. Background Technology

[0002] A complete heavy-duty production line typically consists of multiple functional sections, such as: an assembly section (6 stations); a buffer section (2 stations); a low-pressure testing section (2 stations); a high-pressure testing section (2 stations); and a packaging section (2 stations). These five sections operate independently, requiring "connections" between them for material transfer. The design of these connection points is a critical node in the entire conveying system, directly determining the reliability, stability, and efficiency of the production line. In particular, the following drawbacks exist for heavy-duty plate chain conveyors: First, the load-bearing capacity of the plate chain is insufficient and its stability is poor. Second, since the connecting mechanism and the plate chain are driven by different power sources, slight asynchrony in speed is very likely to occur, which can easily lead to slippage, friction or even jamming between the material and the connecting mechanism. Summary of the Invention

[0003] The purpose of this invention is to provide a plate chain conveyor system. Through the structural design of the plate chain, it can perform heavy-duty conveying with high pressure resistance and high stability. With the synchronous design, it ensures that the cylindrical sleeper assembly and the plate chain are strictly synchronized, so that the movement speed and start-stop time of the sleeper are completely consistent with the plate chain carrying the material. This can eliminate relative displacement and reduce phenomena such as sliding, friction and even jamming caused by the center of gravity shift.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a plate chain conveyor system, comprising: several sets of plate chain conveyors, wherein a connecting transition mechanism is provided in the middle of two adjacent sets of plate chain conveyors for smooth transition conveying of materials between the two sets of plate chain conveyors; the connecting transition mechanism includes a cylindrical sleeper assembly and a transmission sprocket assembly connected to the cylindrical sleeper assembly; and a drive assembly mounted on one set of the plate chain conveyors, the drive assembly being used to drive the plate chain conveyor to run and connecting to the adjacent transmission sprocket assembly, thereby driving the cylindrical sleeper assembly to run in sync with the plate chain conveyor.

[0008] Preferably, the drive assembly includes a mounting frame on which a first motor is mounted, and a mounting shaft fixedly mounted to the output shaft of the first motor. The mounting shaft is used to assemble with each set of wheels to drive the plate roller chain assembly.

[0009] Preferably, the cylindrical sleeper assembly includes two sets of mounting plates, each set of mounting plates having a rotatable roller body mounted laterally via mounting bearings therein; and two sets of support blocks located below the roller body and distributed perpendicularly to the roller body. Each set of support blocks has a support groove to form a receiving groove for accommodating the roller body, and the outer ends of the two support grooves are provided with symmetrical extension grooves, as well as a receiving strip set on the extension groove at a certain angle, and a support crossbar spaced between adjacent support blocks.

[0010] Preferably, the transmission sprocket assembly includes a mounting component and a transmission shaft rotatably mounted to the mounting component. A third transmission wheel is mounted on the inner end of the transmission shaft. The output shaft of the first motor is also mounted with a first transmission wheel.

The transmission sprocket assembly also includes a first end rod, a second end rod, a third end rod, a fourth end rod, a fifth end rod, and a sixth end rod sequentially disposed at the ends of the roller body. Each of the first, second, third, fourth, fifth, and sixth end rods has a second sprocket and a first sprocket distributed internally and externally at its end. A third chain belt, a second chain belt, and a first chain belt are sequentially connected between each pair of first sprockets along the forward direction of the roller chain.

A fourth chain belt is connected between the second sprockets located at the inner ends of the second and third end rods.

[0011] Preferably, the first end rod is positioned at a lower height than the second end rod to form an inclined rolling surface. The receiving strip near the first end rod is tangent to the slat, and the slat is inclined and forms a V-shape with the inclined rolling surface.

A mounting sleeve is vertically mounted on each first mounting block. Each mounting sleeve contains a vertically movable rod, and the top of the vertical rod is provided with an oil box. The oil box contains upwardly extending foam that can contact the roller for lubrication. An oil inlet pipe communicates with each oil box and is connected to an oil pump.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through the structural design of the plate chain conveyor, enables high-pressure resistance and high-stability heavy-duty conveying. Combined with the synchronous design, it ensures that the cylindrical sleeper assembly and the plate chain are strictly synchronized, so that the movement speed and start-stop time of the sleepers are completely consistent with the plate chain conveyor carrying the material. On the one hand, it can eliminate relative displacement, thereby reducing phenomena such as slippage, friction, and even jamming caused by the shift of the center of gravity. On the other hand, when carrying very heavy materials, the weight and friction of the entire moving part are very large. This synchronous design can ensure that the system can start and run smoothly even under heavy loads, without slippage or shaking, protecting the entire mechanical structure from impact.

[0014] 2. As another embodiment of the present invention, the plate roller chain assembly can be provided with forward driving force by the meshing of the rollers and the transmission groove, and the plate roller chain assembly can be provided with horizontal internal support by the rollers rolling on the guide rail frame, thereby meeting the needs of conveying heavy materials.

[0015] 3. The transmission sprocket assembly ensures that the rotation of all rollers is completely synchronized, providing uniform and stable support for material transfer and preventing wear, jamming or noise caused by asynchrony. On the other hand, the flexibility of roller arrangement can also be met.

[0016] 4. An inclined rolling surface is formed by the first end rod and the second end rod. This inclined rolling surface and the receiving strip form a V-shaped downward and upward slope structure. This design can ensure that the pallet can be smoothly connected if it is tilted during the transition, and can prevent the pallet from getting stuck when the center of gravity changes.

Detailed Implementation

[0019] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, 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, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0020] Example 1 Please see Figures 1 to 14 The present invention preferably provides the following technical solution: a plate chain conveyor system, comprising: several sets of plate chain conveyors 1, wherein a connecting transition mechanism is provided in the middle of two adjacent sets of plate chain conveyors 1 for smooth transition conveying of materials between the two sets of plate chain conveyors 1; the connecting transition mechanism includes a cylindrical sleeper assembly and a transmission sprocket assembly connected to the cylindrical sleeper assembly; and a drive assembly mounted on one set of plate chain conveyors 1, the drive assembly being used to drive the plate chain conveyor 1 to run and connect to the adjacent transmission sprocket assembly, thereby driving the cylindrical sleeper assembly to run in sync with the plate chain conveyor 1.

[0021] In this embodiment, a plate chain conveyor 1 and a connecting transition mechanism used in combination with the plate chain conveyor 1 are provided, mainly for conveying heavy materials, such as... Figure 10 , 11 As shown in Figure 14, the material can be a pallet, tray, material support, or logistics trolley, etc. The plate chain conveyor 1 can provide high stability and pressure resistance for conveying heavy materials, while the connecting transition mechanism is located between adjacent plate chain conveyors 1 to receive and smoothly transition the material. Under the action of the drive assembly and the transmission sprocket assembly, such as... Figure 1 , 4 As shown, the drive component serves as the power source for operation. On the one hand, it can drive the plate chain conveyor 1 to run. On the other hand, combined with the transmission action of the transmission sprocket assembly, it drives the cylindrical sleeper assembly to run in sync with the plate chain conveyor 1. When the plate chain conveyor 1 is fast, the connecting transition mechanism automatically speeds up to stably receive materials and pass through quickly. When the plate chain conveyor 1 is slow, the connecting transition mechanism automatically slows down to reduce the center of gravity of the pallet from shifting and improve the stability of the conveying transition. This design, through the structural design of the plate chain conveyor 1, can bear very heavy materials. Combined with the synchronous design, it ensures that the cylindrical sleeper assembly and the plate chain are strictly synchronized, so that the movement speed and start-stop time of the sleeper are completely consistent with the plate chain conveyor 1 carrying the material. On the one hand, it can eliminate relative displacement, thereby reducing phenomena such as slippage, friction, and even jamming caused by the shift of the center of gravity. On the other hand, when carrying very heavy materials, the weight and friction of the entire moving part are very large. This synchronous design can ensure that the system can start and run smoothly even under heavy loads, without slippage or shaking, protecting the entire mechanical structure from impact.

[0022] Example 2 In another embodiment of the present invention, each set of plate chain line 1 includes a guide rail frame 1011 and a plate roller chain assembly mounted on the guide rail frame 1011 and distributed in a ring along the guide rail frame 1011. The plate roller chain assembly includes two sets of wheels 920, which are distributed at both ends of the guide rail frame 1011 and are connected to the roller chain body for transmission. The guide rail frame 1011 is placed inside the roller chain body to provide internal support for conveying the roller chain body.

[0023] Furthermore, the roller chain includes several sets of chain links 912 connected end to end, and a pin 914 is provided at the bottom between two adjacent chain links 912, and a roller 913 is mounted on the pin 914. The outer side of the wheel body 920 is provided with a transmission groove 921 that matches the roller 913. Each chain link 912 has a vertical extension 915 at the end away from the wheel body 920, and a slat 911 is horizontally mounted with each extension 915. The slats 911 are sequentially mounted on each set of chain links 912 to form a complete slat chain structure. When the roller 913 travels on the guide rail frame 1011, it can roll forward with the guide rail frame 1011 itself as the support surface.

[0024] In this embodiment, the structure of the plate chain line 1 is specifically described, such as... Figure 2 and 3 As shown, through the structural design of the plate roller chain assembly, the strips 911 are sequentially assembled on each set of chain pieces 912 to form a complete plate chain structure. The rollers 913 can not only mesh with the transmission groove 921 where the wheel body 920 is located, but also roll on the guide rail frame 1011. Through the meshing of the rollers 913 with the transmission groove 921, the plate roller chain assembly can be provided with forward motion. Through the rolling of the rollers 913 on the guide rail frame 1011, the plate roller chain assembly can be provided with horizontal internal support for conveying, thereby meeting the needs of conveying heavy materials.

[0025] Furthermore, the slats 911 have a U-shaped structure, which is inverted and wrapped around the outer wall of each set of slats 911.

[0026] like Figure 3 , 4 As shown in Figure 5, the structural design of slat 911 can further improve its support capacity.

[0027] Furthermore, the drive assembly includes a mounting bracket 511 on which a first motor 512 is mounted, and a mounting shaft 590 fixedly mounted to the output shaft of the first motor 512. The mounting shaft 590 is used to assemble with each set of wheel bodies 920 to drive the plate roller chain assembly.

[0028] By configuring the driver components, such as Figure 1 , 4 As shown in Figure 5, when the mounting sleeve 812 is working, it can drive the mounting shaft 590 to rotate at high speed, thereby driving the wheel 920 on it to rotate, and then engaging the transmission to drive the chain 912 to move forward in an orderly manner.

[0029] Example 3 In another embodiment of the present invention, the cylindrical sleeper assembly includes two sets of mounting plates 312, each of which has a rotatable roller body 311 mounted laterally via mounting bearings 313; and two sets of support blocks 614 located below the roller body 311 and perpendicularly distributed to the roller body 311. Each set of support blocks 614 has a support groove 612 to form a receiving groove for accommodating the roller body 311. The outer ends of the two support grooves 612 are provided with symmetrical extension grooves 615, and a receiving strip 611 is provided on the extension groove 615 at a certain angle, and a support crossbar 613 is provided at intervals between two adjacent support blocks 614.

[0030] In this embodiment, the connection transition is provided by a cylindrical sleeper assembly, such as... Figure 1 , 6 As shown in Figures 7, 8, and 9, a support structure is designed at the lower part of the roller body 311, including a support block 614 and a support crossbar 613, to provide bottom support for the roller body 311 and prevent it from deforming and sinking. Figure 3 , 5 As shown, the receiving strip 611 is inclined and interacts with the strips 911 on the roller chain to provide stability for the connection.

[0031] Furthermore, the transmission sprocket assembly includes a mounting member 527 and a transmission shaft 528 rotatably mounted to the mounting member 527. A third transmission wheel 591 is mounted on the inner end of the transmission shaft 528. A first transmission wheel 513 is also mounted on the output shaft of the first motor 512, and a first transmission chain 514 is driveably connected between the first transmission wheel 513 and the third transmission wheel 591. A second transmission wheel 515 is fixedly mounted on the outer end of the transmission shaft 528. The transmission sprocket assembly also includes a first end rod 518, a second end rod 519, a third end rod 520, a fourth end rod 521, a fifth end rod 522, and a sixth end rod 523 sequentially disposed at the ends of the roller body 311. Each of the following end rods is provided with a second sprocket 581 and a first sprocket 580 distributed internally and externally at the end of one end rod 518, the second end rod 519, the third end rod 520, the fourth end rod 521, the fifth end rod 522, and the sixth end rod 523. A third chain belt 526, a second chain belt 525, and a first chain belt 524 are sequentially connected between each pair of first sprockets 580 along the forward direction of the roller chain. A second transmission chain 516 is connected between the second sprocket 581 at the inner end of the fourth end rod 521 and the fifth end rod 522 and the second transmission wheel 515. A fourth chain belt 529 is also connected between the second sprocket 581 at the inner end of the second end rod 519 and the third end rod 520.

[0032] With further modifications to the transmission sprocket assembly, preferably, the gaps between the receiving strip 611 and the plate roller chain assembly, and between each roller body 311, are all less than 70mm. For example... Figure 4 , 5As shown in Figures 6, 7, and 8, when the first motor 512 is working, on the one hand, it can drive the mounting shaft 590 to rotate, thereby driving the chain segments 912 on the plate roller chain assembly to move forward in an orderly manner. On the other hand, through the transmission action of the first transmission wheel 513, the first transmission chain 514, and the third transmission wheel 591, it can further drive the second transmission wheel 515 to rotate. When the second transmission wheel 515 rotates, under the transmission action of the second transmission chain 516, it can drive the roller body 311 where the fourth end rod 521 and the fifth end rod 522 are located to rotate. Under the action of the second chain belt 525 and the first chain belt 524, it can also drive the third end rod 520 and the sixth end rod 522 to rotate. The roller 311 containing the end rod 523 rotates, and under the transmission action of the fourth chain belt 529 and the second transmission chain 516, it further drives the second end rod 519 and the first end rod 518 to run. This allows the first end rod 518, the second end rod 519, the third end rod 520, the fourth end rod 521, the fifth end rod 522, and the sixth end rod 523 to complete multi-point drive with a single power source. On the one hand, this ensures that the rotational movement of all rollers 311 is completely synchronized, providing uniform and stable support for material connection and preventing wear, jamming, or noise caused by asynchrony. On the other hand, the flexibility of the arrangement of rollers 311 can also be satisfied.

[0033] Furthermore, the height of the first end rod 518 is lower than that of the second end rod 519 to form an inclined rolling surface. The receiving strip 611 near the first end rod 518 is tangent to the plate 911, and the plate 911 is inclined and forms a V-shaped structure with the inclined rolling surface.

[0034] like Figure 4 , 5 As shown in Figure 8, the first end rod 518 and the second end rod 519 form an inclined rolling surface. This inclined rolling surface and the receiving strip 611 form a V-shaped downward and upward slope structure. This design can ensure that the pallet can be smoothly connected if it tilts during the transition, and can prevent jamming when the center of gravity of the pallet changes. The V-shaped design means that if the load running on it, such as the material trolley, deviates laterally, it will generate a force that automatically returns to the center of the V-shaped groove. Moreover, when the weight distribution of the conveyed material is uneven, the two sides of the V-shaped groove can effectively restrain this torsional tendency, ensuring absolute smooth operation. It is especially suitable for heavy load and high-speed operation conditions.

[0035] Example 4 As another embodiment of the present invention, a lifting and lubrication mechanism is also provided in the guide rail frame 1011. The lifting and lubrication mechanism includes a plurality of third mounting blocks 821 and a plurality of first mounting blocks 813 fixed sequentially on the guide rail frame 1011. A rotatable rotating rod 816 is horizontally mounted between the plurality of third mounting blocks 821. A cam 815 is fixed below each of the rotating rods 816 corresponding to the third mounting blocks 821. A meshing transmission assembly is provided at the end of the rotating rod 816 and is connected to it. The meshing transmission assembly includes a second mounting block 820 and a second motor 824 mounted on the side wall of the second mounting block 820. The output shaft of the second motor 824 passes through a through hole in the second mounting block 820 and is provided with a fourth sprocket 819. A third sprocket 817 is provided at the end of the rotating rod 816. A chain 818 is connected to the fourth sprocket 819 and the third sprocket 817. The mounting sleeve 812 is vertically mounted on each first mounting block 813. Each mounting sleeve 812 has a vertically movable vertical rod 822 installed inside, and a circular plate 814 located at the bottom of the vertical rod 822 and acting on the top of the cam 815. An oil box 830 is provided at the top of the vertical rod 822. The oil box 830 has an upwardly extending foam 811 inside, which can contact the roller 913 for lubrication. An oil inlet pipe 831 is connected to each oil box 830 and each oil inlet pipe 831 is connected to an oil pump. In this embodiment, through a further lifting and lubrication mechanism, when the second motor 824 is working, the chain 818 between the fourth sprocket 819 and the third sprocket 817 can further drive the rotating rod 816, which in turn drives several cams 815 to drive, thereby slightly displacing and lifting the height of the foam 811 so that it contacts the roller 913, thereby achieving a lubrication effect.

[0036] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part of a unit. Detachable installation can take many forms, such as through a combination of plug-in and snap-fit ​​connections, or through bolt connections.

[0037] In addition, all the connections / connections mentioned in the article do not refer to direct connection of components, but rather to the formation of a better connection structure by adding or removing connecting accessories according to the specific implementation situation.
