Four lifting components 202 are fixedly installed at an equal distance on the bottom of the lifting cover 201. The four lifting components 202 are connected to each other through the transmission component 203.

[0040] The positioning mechanism 3 is fixedly installed inside the lifting cover 201. The positioning mechanism 3 includes a servo motor B301 fixedly installed on the inner wall of the lifting cover 201. A spline rod 3011 is fixedly installed on the output end of the servo motor B301.

An expansion component 303 is fixedly installed on the outer side of the bottom of the spline rod 3011 through a threaded sleeve 3012. Four rotating components 304 are evenly spaced and installed on the outer side of the expansion component 303.

[0041] The closed chain is tensioned and positioned by the positioning mechanism 3, and then the closed chain is driven to rotate to adjust the tightening processing position of the tensioned chain. At the same time, the horizontal position of the tightening mechanism 7 is adjusted by the adjusting mechanism 6, so that the processing position of the tightening mechanism 7 can be adjusted according to the chain specifications;

[0042] Among them, when the servo motor B301 is powered on, it drives the toothed disc 302 to rotate through the spline rod 3011, and the rotating toothed disc 302 drives the expansion component 303 to expand and move through the spline groove 3022.

The transmission slide rod 3034 is fixedly mounted on the top of one end of the telescopic rod 3033.

[0044] Among them, the transmission slide rod 3034 extends to the inside of the spline groove 3022. When the rotating toothed disc 302 rotates, the four spline grooves 3022 and the four transmission slide rods 3034 cooperate to push the four telescopic rods 3033 to telescopically move inside the slide rod 3032. The four telescopic rods 3033 that telescopically move drive the four rotating components 304 to perform synchronous horizontal reciprocating movement, which is convenient for adjusting the positions of the four rotating components 304 according to the chain specifications, and the chain is tensioned and positioned by the moving rotating components 304.

When the electric push rod 507 is energized, the closed rectangular frame is driven to fold and move through the linkage shaft arm 506. The folded and moving closed rectangular frame drives the V-shaped material shifting structure composed of the four material shifting pieces 504 and the four mounting angle pieces 503 to reciprocate with the lifting rod 502 as the axis.
