[0027] The objectives, advantages, and features of the present invention are illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of the application of the technical solutions of the present invention. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

[0028] In the description of the solution, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "back," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplification. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] The centering conveyor disclosed by the utility model is described below in conjunction with the accompanying drawings. Figure 1 As shown, it includes a frame 100 and a central roller 200 arranged on the frame 100 , wherein the central rollers 200 are in two groups and are symmetrically distributed on both sides of a middle support rod 300 , and the middle support rod 300 is mounted on the frame 100 .

[0030] As attached Figure 1 , Attachment Figure 2As shown, the frame 100 is further provided with side guards on both sides thereof, and the side guards include at least an oblique side guard assembly 400, and the oblique side guard assembly 400 includes a fixing frame 410 fixed on the frame 100, and the fixing frame 410 is located at one side top corner of the output end of the centered conveyor, so that the two oblique side guard assemblies 400 cooperate to form a bell mouth, and a plurality of roller assemblies 420 are provided on the fixing frame 410, and the roller assembly 420 includes a group of concentric rollers 421 with axes extending in the vertical direction, and the rollers 421 of adjacent rows of roller assemblies 420 are staggered in the vertical direction and the projections of the rollers 421 of adjacent rows of roller assemblies 420 on the horizontal plane partially overlap, and more preferably, the diameter of the roller 421 is slightly smaller than the spacing between the two rotating shafts of adjacent roller assemblies 420, and the thickness of the roller 421 is slightly smaller than the spacing between adjacent rollers 421 on the roller assembly 420, so that the gap between the roller assemblies 420 is as small as possible.

[0031] The roller assembly 420 of the oblique sidewall assembly 400 may be arranged in only one row. Preferably, in order to ensure structural strength, the oblique sidewall assembly 400 is provided with multiple layers of installation space, with a row of roller assemblies 420 installed in each layer of installation space.

[0032] As attached Figure 3 , Attachment Figure 4 As shown, the fixing frame 410 includes vertical side panels, each of which is provided with a vertical connecting plate extending toward the side of the central roller 200. The vertical connecting plate at the outer end is connected to the fixing plate at the output end of the frame 100, and the vertical connecting plate at the inner end is connected to the end of the straight sidewall assembly 700 of the sidewall. The lower side of the vertical side panel is connected to a horizontal fixing plate, which is fixed to the frame 100. A reinforcement plate is provided between the horizontal fixing plate and the vertical side panel. The fixing frame 410 is provided with multiple layers of mounting slots 430, each of which is provided with a row of the roller assemblies 420. In order to facilitate the assembly of the fixing frame 410 and the mounting slot 430, a plurality of one-to-one corresponding waist-shaped connecting holes 440 are provided on the vertical connecting plate of the fixing frame 410 and each mounting slot 430. The fixing frame 410 and the mounting slot 430 are fastened by a T-shaped screw 450 and a nut 460 passed through the waist-shaped connecting hole. One end of the T-shaped screw is a transverse portion. The thickness of the transverse portion is equivalent to the width of the waist-shaped connecting hole 440 so that it can pass through the waist-shaped connecting hole 440. The length of the transverse portion is greater than the width of the waist-shaped connecting hole so that the transverse portion rotates a certain angle, such as 90°, after passing through the waist-shaped connecting hole 440. At this time, the two wings of the transverse portion are stuck on both sides of the waist-shaped connecting hole 440 so that it cannot withdraw from the waist-shaped connecting hole 440. Therefore, the nut 460 and the T-shaped screw 450 can be locked from the outside of the fixing frame 410.

[0033] As attached Figure 4As shown, in order to facilitate the installation of the rotating shaft of the roller assembly 420, the installation groove 430 includes a C-shaped groove main body 431, and the upper and lower ends of the C-shaped groove main body 431 respectively have groove openings facing the C-shaped connecting groove 432 of the C-shaped groove main body 431, and the upper horizontal plate and the lower horizontal plate of the C-shaped connecting groove 432 are respectively provided with a row of connecting holes in opposite positions, and the end of the rotating shaft of the roller assembly can be conveniently connected to the C-shaped connecting groove 432 through the connecting holes in opposite positions.

[0034] Furthermore, to improve the support of the overall structure, the top of the C-shaped groove body 431 is flush with the top of the upper C-shaped connecting groove 432, and the bottom of the C-shaped groove body 431 is flush with the bottom of the lower C-shaped connecting groove 432. After the mounting grooves 430 are assembled on the fixing frame 410, the C-shaped groove bodies 431 of adjacent mounting grooves 430 mate with each other, and the C-shaped connecting grooves of adjacent mounting grooves 430 mate with each other. As a result, the lower mounting grooves 430 can effectively support the upper mounting grooves 430, thereby reducing the shear force on the cross-shaped bolts.

[0035] As attached Figure 1 , Attachment Figure 5 , Attachment Figure 6 As shown, the two groups of the center rollers 200 are driven by friction drive assemblies 500. There are two friction drive assemblies 500, and each friction drive assembly 500 is used to drive a group of center rollers 200 to rotate for conveying. The friction drive assembly 500 includes a frame 510, and a group of equal-height and parallel unpowered rollers 520 are provided on the frame 510. The unpowered rollers 520 are provided with friction drive belts 530, and the friction drive belts 530 are also mounted on a drive roller 540. The drive roller 540 is rotatably connected to the base frame 550 at the bottom of the frame 510. The drive roller 540 is connected to a reducer 560 that drives its rotation. The reducer 560 is connected to the side of the base frame 550 through a flange and the reducer 560 is connected to the motor 570.

[0036] The friction drive belt 530 is also connected to the tensioning roller 570 and the steering roller 580 located on its outside. The tensioning roller 570 and the steering roller 580 are arranged on the base frame 550 and their top heights are similar. They are located on the same side of the drive roller 540 and can be adjusted to a horizontal position on the base frame 550.

[0037] As attached Figure 1 As shown, in order to improve the smoothness of the output of goods, the output end of the central conveyor is provided with an output roller 600 located in the middle position and with an axis extending along the width direction of the central conveyor.
