[0038] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0039] First, combine Figures 1-6 The long roller sorting chain according to an embodiment of the present invention is used for sorting and conveying express delivery, and its application scenarios are very wide.

[0040] like Figures 1-6 As shown, the long roller sorting chain of this utility model embodiment includes: roller conveyor chain plate 1 and drive module 2.

[0041] Specifically, such as Figures 1-6As shown, in this embodiment, the roller conveyor chain 1 transports express packages to be sorted. The roller conveyor chain 1 has several rotatable rollers 112. The length direction of the rollers 112 is parallel to the conveying direction of the roller conveyor chain 1. When the rollers 112 rotate, they will drive the express packages on the rollers 112 to move perpendicular to the conveying direction. The roller conveyor chain 1 includes several rows of chain plate assemblies 11. The several rows of chain plate assemblies 11 are connected end to end in sequence. The chain plate assemblies 11 of adjacent rows are staggered and arranged in a centrally symmetrical manner. The staggered connection can improve the connection stability and structural strength, and reduce the risk of tearing of the chain plate assemblies 11.

[0042] Furthermore, such as Figures 1-6 As shown, in this embodiment, the chain plate assembly 11 includes at least two chain plates with different numbers of rollers 112. That is, the chain plate assembly 11 includes at least two chain plates, which are located in the same row, and each chain plate has a different number of rollers 112 and a different length. In this embodiment, three chain plates are used, and the chain plate in the middle has the most rollers 112.

[0043] Furthermore, such as Figures 1-6 As shown, in this embodiment, the chain plate includes: a chain plate body 111, a plurality of rollers 112, and a plurality of mounting components; the plurality of rollers 112 are arranged at equal intervals on the chain plate body 111, improving aesthetics and the uniformity of the force applied to the express delivery; each of the rollers 112 corresponds to one of the mounting components, and the rollers 112 are rotatably mounted on the chain plate body 111 through the mounting components; the rollers 112 protrude from the top and bottom surfaces of the chain plate body 111, so when the rollers 112 rub against the drive module 2, it does not affect the movement of the chain plate body 111, and at the same time, it is convenient for the rollers 112 to drive the express delivery to change its direction of movement, thereby realizing sorting. Compared with belt conveyors, the chain plate is easy to disassemble and assemble, and only one part needs to be replaced when damaged, effectively reducing production costs.

[0044] Furthermore, such as Figures 1-6 As shown, in this embodiment, the mounting assembly includes: a connecting shaft 113 and a pair of bearings 114; both ends of the connecting shaft 113 are fixed to the chain plate body 111; a roller 112 is sleeved on the connecting shaft 113, and both ends of the roller 112 are rotatably connected to the connecting shaft 113 via a pair of bearings 114. In this embodiment, the connecting shaft 113 is made of metal, and the roller 112 is made of plastic with a high coefficient of friction to prevent the express packages to be sorted from slipping. Since the roller 112 generates friction when rotating relative to the connecting shaft 113, causing wear, the use of bearings 114 can reduce wear.

[0045] Furthermore, such as Figures 1-6 As shown, in this embodiment, the bearing 114 is a stepped bearing 114, and the stepped surface of the bearing 114 is in contact with the end face of the roller 112, thereby reducing the wear of both ends of the roller 112.

[0046] Furthermore, such as Figures 1-6 As shown, in this embodiment, connecting sleeves are fixed on both sides of the chain plate body 111. The connecting sleeves of adjacent rows of chain plate bodies 111 mesh with each other. The external chain plate connecting shaft 113 is inserted and fixed in the connecting sleeve, which realizes the connection of adjacent rows of chain plate bodies 111. The installation is quick, easy to replace, and low in cost. The connecting sleeve includes: a pair of first connecting sleeves 115 and a plurality of second connecting sleeves 116. The pair of first connecting sleeves 115 are fixed at both ends of the chain plate body 111, and the plurality of second connecting sleeves 116 are fixed at equal intervals between the pair of first connecting sleeves 115. The pair of first connecting sleeves 115 and the plurality of second connecting sleeves 116 are concentrically arranged. The thickness h of the first connecting sleeve 115 is half the thickness of the second connecting sleeve 116. The interlaced connection greatly enhances the structural strength.

[0047] Specifically, such as Figures 1-6 As shown, in this embodiment, the drive module 2 is located in the sorting area and below the roller conveyor chain plate 1. The drive module 2 drives the rollers 112 on the roller conveyor chain plate 1 to rotate, thereby changing the conveying direction of the express packages. Further, the drive module 2 includes: a drive mechanism and several rotary drive components; the output end of the drive mechanism is connected to the several rotary drive components; the several rotary drive components are equally spaced below the roller conveyor chain plate 1, each rotary drive component is positioned between four adjacent rollers 112, and the four adjacent rollers 112 are arranged at four corners; the drive mechanism drives the several rotary drive components to rotate at a certain angle, causing the rotary drive components to rub against the adjacent diagonally arranged rollers 112, thereby driving the rollers 112 to rotate, realizing automated sorting of express packages.

[0048] Furthermore, such as Figures 1-6 As shown, in this embodiment, the rotary drive assembly includes: a rotating shaft 21, a connecting rod 22, a mounting shell 23, a pair of rollers 24, and a pair of fixed shafts 25; the mounting shell 23 is fixed to the top of the rotating shaft 21, and the connecting rod 22 is fixed to the bottom of the rotating shaft 21, and the connecting rod 22 is hinged to the drive mechanism; the pair of rollers 24 are respectively fixed inside the mounting shell 23 through the pair of fixed shafts 25, the length direction of the fixed shafts 25 is perpendicular to the length direction of the roller 112, and the rollers 24 protrude from the mounting shell 23; the drive mechanism drives the connecting rod 22 to rotate, thereby driving the rotating shaft 21 and the mounting shell 23 to rotate, thereby driving the rollers 24 to rotate. The drive mechanism can be a linkage drive mechanism to drive several rotary drive assemblies to rotate simultaneously by a certain angle.

[0049] Working principle: An external drive device drives the roller conveyor chain 1 to move along the length of the roller 112, conveying the express packages to be sorted. When the express package moves to the sorting area, the linkage drive mechanism drives a pair of rollers 24 on several rotary drive components to rotate at a certain angle, so that the pair of rollers 24 respectively connect with the adjacent diagonally opposite rollers 112. When the roller 112 moves along its length, it will generate friction with the rollers 24, causing the roller 112 to rotate. Under the action of inertia and the driving action of the roller 112, the express package to be sorted will move to the grid perpendicular to the roller conveyor chain 1, realizing the automated sorting of express packages.

[0050] Above, refer to Figures 1-6 The present invention describes a long roller sorting chain according to an embodiment of the present invention, which can realize automated and rapid sorting of express delivery, with a simple and compact structure; the chain plates are easy to disassemble and replace, and the cost is low.
