[0033] In this embodiment, a heavy-duty plate chain conveyor line is provided, such as Figure 1 As shown, the main body consists of a sprocket drive assembly and a guide rail frame. Through the structural design of the plate roller chain assembly, such as... Figure 3 , 4 As shown in Figures 5 and 6, through several sets of chain link units 211 connected end to end, and rollers 215 installed at the bottom of the chain link units 211, combined with the structural design of the driving sprocket and driven sprocket, the rollers 215 can mesh with the driving sprocket and driven sprocket during meshing transmission to achieve power transmission. When moving to the guide rail frame, the rollers 215 can roll freely on the guide rail frame, thus enabling the plate moving forward stably and orderly on the guide rail frame. Figure 3 As shown, the heavy-duty plate chain conveyor line constructed with the above structure has a highly stable and pressure-resistant plate chain conveying function.
[0034] Furthermore, the drive sprocket and the driven sprocket have the same structure.

[0035] Provided are a type of driving sprocket and driven sprocket, such as Figure 4 , 5 As shown, the chain groove 313 is perfectly matched with the roller 215. When the sprocket body 311 is in motion, the chain groove 313 and the roller 215 can mesh, thereby pushing the plate forward.
[0036] Furthermore, the loop assembly includes extensions 213 that are laterally connected to the top of the chain link unit 211 and distributed at four corners, with each extension 213 having a screw hole 212.
[0037] Furthermore, the plate body includes a strip 111, on which a plurality of through holes 112 are provided. The lug assembly also includes a bolt 220, which passes through the through holes 112 from top to bottom and is fixedly assembled with a screw hole 212.

Figure 3 , 4 As shown, the top of the connecting shaft 214 of a single group can be fitted with the corresponding strip 111 by bolts 220. When several plates are assembled on several sets of chain link units 211 connected at the beginning and end, they are used to form a plate chain.

[0040] In this embodiment, a guide rail frame is provided, such as Figure 1 , 3 As shown, each set of long rails 511 is arranged vertically opposite each other and placed inside the plate roller chain assembly. When the rollers 215 engage and move close to the guide rail frame, the guide slope 512 guides the rollers 215 to transition onto the long rails 511 for subsequent smooth support and conveying.
[0041] Furthermore, the sprocket drive assembly consists of three sets, located on both sides and in the middle of the support beam 811.
[0042] Furthermore, a number of support beams 811 are symmetrically fixed with transversely arranged support rails 611 in the middle, and rollers 612 are assembled on the lower surface of each strip 111 and correspond one-to-one with the support rails 611. The rollers 612 can roll on the support rails 611.
[0043] By distributing the sprocket drive components and further configuring the support rails 611, the conveying stability and load-bearing capacity of the plate chain can be further improved.

Each slide rail 712 has a movable block 715 slidably mounted inside. A rotatable drive shaft 713 is laterally connected between the two movable blocks 715. The drive shaft 713 is fixedly positioned with the mounting hole 312 in the middle of each sprocket body 311. A bushing 718 is mounted at the end of the movable block 715, and a threaded sleeve 716 is rotatably mounted with the bushing 718. The end of the threaded sleeve 716 away from the bushing 718 passes through the through groove on the mounting bracket 711 and is threadedly connected to the threaded sleeve 716 fixed on the inner wall of the mounting bracket 711.
[0046] In this embodiment, the screw-adjusted frame is further configured, such as... Figure 1 , 7 As shown, when the adjusting screw 714 is manually rotated, the movable block 715 is pushed to slide within the slide rail 712, which adjusts the horizontal position of the slide rail 712, thereby driving the driven sprocket to be horizontal, and thus adjusting the distance between it and the driving sprocket to adjust the tension of the plate chain.
[0047] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part. Among these, there are various ways to install detachably, such as by using a combination of plug-in and snap-fit, or by using bolts for connection, etc.
[0048] 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.
