The three cloth rolls 17 are respectively sleeved on the surfaces of the three polished rods 6, and a clamping mechanism 19 is provided on the side of each slot 3. The clamping mechanism 19 cooperates with the polished rod 6 in front of the cross bar 1, and the rotating rod is driven by the stepping motor 2 to rotate 180 degrees. The rotating bracket 4 will also rotate 180 degrees at the same time, and the positions of the two polished rods 6 will be interchanged. The new cloth roll 17 will move to the front of the cross bar 1 to replace the cloth roll 17. At the same time, under the action of the clamping mechanism 19, the cloth roll 17 can be clamped, and the stability of the polished rod 6 during use can be guaranteed.

[0025] The middle end surface of the polished rod 6 is movably sleeved with a first locking block 7, and a matching disk 11 is provided at the rear of the first locking block 7, and a positioning disk 10 is fixedly provided at the rear of the matching disk 11. The positioning disk 10 and the matching disk 11 are both fixedly installed on the surface of the polished rod 6, and the first locking block 7 is close to One end of the matching disk 11 is provided with a guide rod 14, and the surface of the guide rod 14 movably passes through the positioning disk 10 and the matching disk 11, and a tension spring 15 is installed on the surface of the guide rod 14 behind the positioning disk 10. At this time, the pushing surface 13 at the end of the first locking block 7 can push the inner wall of the sleeve surface 16, so that the end of the cloth winding drum 18 is separated from the surface of the matching disk 11, making it convenient for the staff to remove the cloth winding drum 18.

[0026] A second locking block 8 is provided in front of the first locking block 7. The second locking block 8 is movably sleeved on the surface of the light rod 6. The end of the second locking block 8 away from the first locking block 7 is set as a pushing surface 13, and the end of the second locking block 8 close to the first locking block 7 is set as an inclined surface 12. The second locking block 8 corresponds to the first locking block 7. When the second locking block 8 moves toward the center axis 5, the second locking block 8 can be inserted into the inside of the cloth winding drum 18. At this time, the second locking block 8 and the first locking block 7 have a squeezing and fixing effect on the cloth winding drum 18.

[0027] A fixed block 20 is provided on the side of the slot 3, and the clamping mechanism 19 includes a cylinder 21. The cylinder 21 is mounted behind the fixed block 20 by bolts. A telescopic rod 22 is movably provided in front of the fixed block 20. The output end of the cylinder 21 is fixedly connected to the telescopic rod 22. An L-shaped rod 23 is fixedly installed in front of the telescopic rod 22. A mounting ring 24 is fixedly provided at the end of the L-shaped rod 23. A rotating ring is installed on the surface of the mounting ring 24 close to the second fixing block 8. The surface of the rotating ring is fixedly connected to the second fixing block 8, and the diameter of the rotating ring is the same as the diameter of the matching disk 11. The cylinder 21 drives the telescopic rod 2 2 moves, the telescopic rod 22 drives the L-shaped rod 23 to move, and the L-shaped rod 23 can also drive the mounting ring 24 and the second locking block 8 to move. When the cylinder 21 extends, the telescopic rod 22 moves toward the front of the cross bar 1, and at the same time, the L-shaped rod 23 drives the mounting ring 24 and the second locking block 8 to move forward, and the surface of the second locking block 8 will be separated from the interior of the cloth winding drum 18. Then, when the cylinder 21 contracts, the telescopic rod 22 moves toward the rear of the cross bar 1, and at the same time, the L-shaped rod 23 drives the mounting ring 24 and the second locking block 8 to move backward, and the surface of the second locking block 8 can be inserted into the interior of the cloth winding drum 18.

[0028] Three positioning blocks 25 are evenly installed in front of the cross bar 1. The three positioning blocks 25 correspond to the three fixed blocks 20 respectively. A limiting groove 26 is provided on the surface of the positioning block 25. A sliding block 27 is slidably installed inside the limiting groove 26. A snap-fit groove 28 is provided at one end of the sliding block 27 close to the light rod 6. A positioning surface 9 is provided on the surface of the light rod 6 close to the central axis 5. The snap-fit groove 28 is sleeved on the outer surface of the positioning surface 9. A second positioning pin 31 is installed at the middle end of the top of the sliding block 27. A first positioning pin 30 is installed in the middle of the telescopic rod 22. A connecting rod 29 is installed between the second positioning pin 31 and the first positioning pin 30 through a rotating shaft. 1 and the first positioning pin 30. When the telescopic rod 22 moves, the first positioning pin 30 can pull the connecting rod 29 and the second positioning pin 31, and the second positioning pin 31 can drive the sliding block 27 to move. When the cylinder 21 drives the telescopic rod 22 to extend outward, the telescopic rod 22 can pull the sliding block 27 through the connecting rod 29, so that the sliding block 27 slides parallel to the surface. At this time, the engaging groove 28 will be out of the surface of the positioning surface 9. When the cylinder 21 drives the telescopic rod 22 to retract, the telescopic rod 22 can push the sliding block 27 through the connecting rod 29, so that the sliding block 27 slides parallel to the surface. At this time, the engaging groove 28 will be engaged with the surface of the positioning surface 9, thereby ensuring the stability of the polished rod 6 during operation.

[0029] Four legs are evenly installed at the bottom of the crossbar 1. The four legs evenly divide the bottom of the crossbar 1 into three bottom frames. The three bottom frames are respectively installed directly below the three slots 3. The legs can support the crossbar 1 to ensure the stability of the device when in use.

[0030] A collecting frame 32 is provided inside the bottom frame, and an arc-shaped surface 33 is fixedly installed in front of the collecting frame 32. The collecting frame 32 can store the cloth reel 18. When the central axis 5 rotates and the light rod 6 is perpendicular to the ground, the gravity of the cloth reel 18 will cause the cloth reel 18 to fall off from the surface of the matching disk 11 and the first locking block 7, and the cloth reel 18 can fall into the collecting frame 32.

[0031] Working principle: First, after the cloth on the cloth roll 17 is used up, the staff will sleeve a new cloth roll 17 on the surface of the light rod 6 behind the cross bar 1, sleeve the cloth winding drum 18 on the surface of the first locking block 7, and make the sleeve surface 16 clamped on the surface of the matching disk 11, then the cylinder 21 drives the telescopic rod 22 to extend forward, the telescopic rod 22 will move toward the front of the cross bar 1, and the L-shaped rod 23 drives the mounting ring 24 and the second locking block 8 to move forward, the surface of the second locking block 8 will disengage from the inside of the cloth winding drum 18, and the second locking block 8 will move out from the surface of the light rod 6. When the telescopic rod 22 is extended forward, the telescopic rod 22 can pull the sliding block 27 through the connecting rod 29 to make the sliding block 27 slide parallel to the cloth winding drum. At this time, the engaging groove 28 will disengage from the surface of the positioning surface 9. Since the second locking block 8 does not exert an extruding force on the cloth winding drum 18, the elastic force of the tension spring 15 can push the first locking block 7 forward. At this time, the pushing surface 13 at the end of the first locking block 7 can When the cloth roll 18 is in the forward position, the cloth roll 17 is moved to the front of the drawer 32 and the cloth roll 18 is moved to the front of the drawer 32.
