A plurality of mesh belt strips 1 are connected in sequence to form a complete mesh belt chain. When conveying materials, a belt conveyor is arranged on the lower side of the mesh belt chain to contact the lower part of the ball 3, thereby driving the ball 3 to rotate, and the upper part of the ball 3 is used to drive the material to be conveyed along the rotation direction of the ball 3. By arranging the sliding bar 6, the surface of the ball 3 can be attached. When the ball 3 rotates, the plurality of sliding bars 6 cooperate to make the ball 3 more stable when rotating without shaking. At the same time, since the contact area between the sliding bar 6 and the ball 3 is small, the sliding friction between each other is small, so the ball 3 rotates more smoothly. The conveyor below adopts different structural forms, which can realize: normal straight conveying, buffer conveying, double speed conveying, lateral alignment, rotation during travel, automatic sorting conveying and other applications. The ball mesh belt + belt friction drive roller is adopted to realize the automatic sorting function. The lower belt is driven by an electric roller, which is convenient for the host computer to control the direction, speed, etc. In practical applications, there are many different application modes of the mesh belt chain in the utility model.

[0027] The upper side of the mesh belt strip 1 is recessed with an installation groove 7, the bottom of the installation groove 7 is recessed with a lower groove body 8, the lower driving hole 5 is connected to the bottom of the lower groove body 8, a mounting plate 9 is installed in the installation groove 7, the lower side of the mounting plate 9 is provided with an upper groove body 10 aligned with the lower groove body 8, one end of the upper driving hole 4 is connected to the upper side of the mounting plate 9, and the other end is connected to the bottom of the upper groove body 10, the upper groove body 10 and the lower groove body 8 cooperate to form a rotating cavity 2; the sliding bar 6 includes an upper section 11 and a lower section 12, the upper section 11 is arranged on the groove wall of the upper groove body 10, and the lower section 12 is arranged on the groove wall of the lower groove body 8. Such a setting facilitates the installation of the ball 3. During installation, the ball 3 is first installed in the lower groove body 8, and then the mounting plate 9 is installed into the mounting groove 7 from the groove position of the mounting groove 7, so that the upper groove body 10 on the mounting plate 9 covers the upper part of the ball 3, thereby allowing the ball 3 to be installed in the rotating cavity 2 formed by the upper groove body 10 and the lower groove body 8.

[0028] The mounting plate 9 is fixed in the mounting groove 7 by ultrasonic welding. Compared with the traditional snap-fit ​​installation, the mounting plate 9 can be more firmly installed in the mounting groove 7 by ultrasonic welding, and the mounting plate 9 is integrated with the mounting groove 7, so that the structure is more solid, and the mounting plate 9 is not likely to fall out of the mounting groove 7 during use, causing the problem of the ball 3 falling off.

[0029] The groove wall of the installation groove 7 gradually tilts and approaches from the groove opening to the groove bottom, and the side of the installation plate 9 and the groove wall of the installation groove 7 are tilted in coordination. In the tilted setting, during the ultrasonic welding process, the installation plate 9 is continuously pushed toward the groove bottom of the installation groove 7 by the welding equipment, and is squeezed by two inclined surfaces and melted under the action of ultrasonic waves, so that the two inclined surfaces are gradually melted and welded together, guiding the lower side of the installation plate 9 and the groove bottom of the installation groove 7 to fit.

When the latch 17 is inserted, the support rod 20 is first pulled out of the mounting hole 19 to make the mounting hole 19 vacant. When the latch 17 is inserted into the first fixing hole 15 and the second fixing hole 16, the block 21 squeezes the block 21 through the hole wall of the second fixing hole 16 when entering the second fixing hole 16, so that the position of the latch 17 at the block 21 can be squeezed toward the middle of the latch 17 by means of the gap generated by the mounting hole 19 and the long hole 22, so that the outermost end of the block 21 can enter the second fixing hole 16, and when it is pushed to the position of the annular groove 18 of the first fixing hole 15, the elasticity of the latch 17 itself pushes the block 21 into the annular groove 18, so that the block 21 and the annular groove 18 are buckled and connected, which can prevent the latch 17 from falling off. Furthermore, after the latch 17 is installed, the support rod 20 is inserted into the installation hole 19, so that the position of the block 21 can be supported to prevent the block 21 from falling out of the annular groove 18 due to the depression of the position of the block 21 during use.
