The chassis assembly 1 is preferably made of metal and has a rectangular frame structure design, and a plurality of fixed pads 13 are provided on the left and right sides of the upper end of the chassis assembly 1 for symmetrically fixing and connecting the roller conveyor assembly 2 by bolts. The roller conveyor assembly 2 is divided into two parts, left and right, specifically including a left crossbeam 21 and a right crossbeam 22, and the left and right crossbeams are opposite. A row of cantilever roller assemblies 23 are fixedly connected, and the cantilever roller assembly 23 includes a transmission shaft 26. A cylinder 24 is fixed to the inner surface of the transmission shaft 26, and a transmission sprocket 27 is installed on the side of the transmission shaft 26 facing away from the cylinder 24, and a bearing 25 is provided on the outside of the transmission shaft 26. The cylinder 24 can be keyed or bolted to the transmission shaft 26, and the transmission sprocket 27 can be keyed or bolted to the transmission shaft 26. The transmission sprocket 27 is driven by a chain to rotate the cylinder 24 through the transmission shaft 26 to perform forward and reverse motion to achieve the purpose of reciprocating transportation. The guide assembly 3 is symmetrically fixed to the front end of the left beam 21 and the right beam 22 of the roller conveyor assembly 2 by bolts.

[0031] The transmission assembly 4 is also included. The transmission assembly 4 is arranged in the base assembly 1 and drives the roller cantilever roller assembly 23 to move forward and reverse through the transmission assembly 4.

[0032] Among them, the transmission assembly 4 includes a drive motor 41 and a transmission chain 42. The drive motor 41 is fixed in the base assembly 1 and drives the cantilever roller assembly 23 to move forward and reverse through the transmission chain 42. Among them, the drive motor 41 rotates alternately counterclockwise and clockwise.

[0033] It is understandable that the specific functions of the drive motor 41 and the transmission chain 42 in this embodiment can be obtained by those skilled in the art based on the existing technology, and the structure and working principle of the drive motor 41 and the transmission chain 42 will not be described in detail here.

[0034] In the specific implementation process, the chassis assembly 1 is supported, the driving motor 41 drives the transmission chain 42, and the chain then rotates the cantilever roller assembly 23 through the transmission sprocket 27 to perform forward and reverse motion to achieve the transportation purpose.

[0036] It should be noted that the outer side of the cylinder 24 of the cantilever roller assembly 23 is designed with a Z-shaped groove structure, which corresponds to the Z-shaped groove of the opposite cylinder 24, forming a high-precision limiting structure for the material to improve working accuracy.

[0037] The transmission sprockets 27 are designed with a double-row sprocket structure, and every three adjacent transmission sprockets 27 are staggeredly connected by two annular chains for transmission.

[0039] Furthermore, the guide plate 31 is designed with an inverted bevel structure, and the guide wheel assemblies 33 are arranged in sequence according to the inverted bevel of the guide plate 31, forming a trumpet-shaped structure corresponding to the opposite guide assembly 3, which gradually narrows from the outside to the inside to improve the docking accuracy with other equipment.

[0040] In summary, when the present invention is used, the entire device is supported by the chassis assembly 1. A plurality of fixed pads 13 are provided on the left and right sides of the upper end of the chassis assembly 1, and are symmetrically fixedly connected to the roller conveyor assembly 2 by bolts to ensure that the roller conveyor assembly 2 works stably on the chassis assembly 1. The left crossbeam 21 and the right crossbeam 22 extend to the front and rear ends of the chassis assembly 1, and are symmetrically fixedly connected to a row of cantilever roller assemblies 23 on the left and right sides. The transmission shaft 26 passes through the left crossbeam 21 and the right crossbeam 22 horizontally, and the other end is connected to the transmission sprocket 27. A double-row sprocket structure design is used, and every three adjacent transmission sprockets 27 Two annular chains are staggered and connected for transmission to improve the stability of the roller conveyor assembly 2 during the conveying process and ensure the load-bearing capacity of the entire equipment; at the same time, the outer side of the cylinder 24 is designed with a Z-shaped groove structure and the guide plate 31 in the guide assembly 3 is designed with an inverted bevel structure. The two sides of the guide plate 31 are symmetrically formed into a trumpet structure that gradually narrows from the outside to the inside to improve the working accuracy of the equipment and the docking accuracy with other equipment, so that the conveying equipment has a larger load capacity, is more stable, and has higher working accuracy. During installation or maintenance and replacement, the entire roller conveyor assembly 2 and the drive motor 41 can be installed and replaced, which is highly practical.
