[0020] The driving mechanism 4 further comprises two first three-leaf plates 32, two second three-leaf plates 33 and a driving telescopic joint 30.

[0021] The gap between the adjacent leaves on the first three-leaf plate 32 and the second three-leaf plate 33 is matched with the opening 23.

[0022] The driving mechanism 4 further comprises two connecting rods 24 and a telescopic electric clamp 31. The connecting rod 24 is pivoted on the inner side of the second three-leaf plate 33, and the telescopic end of the telescopic electric clamp 31 is connected with the connecting rod 24.

[0026] Working principle: when in use, the plurality of auxiliary slide seats 5 and the dismounting mechanism 10 are moved and fixed at equal intervals on the track 2. Then the cloth is sent into the workbench 1 and contacted with the plurality of circular net drum mechanisms 7. Then the driving wheel 12 is controlled to drive the belt 13 to force the drum shell 8 to rotate, and the electromagnet 27 is controlled to be attracted to the magnetic segment assembly 15, so that the magnetic segment assembly 15 extrudes the drum shell 8 to force the drum shell 8 to extrude the cloth.

[0027] When the work is completed, the plurality of drum shells 8 are controlled to be close to each other and contacted, then the first driving sliding block 25 and the second driving sliding block 29 are controlled to move the circular net drum mechanism 7 to the position of the opening 23, then the first three-leaf plate 32 is rotated, so that the second three-leaf plate 33 overlaps the first three-leaf plate 32, thereby the outlet hole corresponds to the opening 23, then the telescopic electric clamp 31 close to the first driving sliding block 25 is separated from the magnetic rod end body 21, and the clamping seat 20 is magnetically connected with the end of the magnetic rod end body 21, and the above operation is repeated to magnetically connect the magnetic rod assembly 17 in the plurality of circular net drum mechanisms 7 with the clamping seat 20. Then the connecting rope 19 is pulled to force the magnetic segment assembly 15 to be elongated, so that the universal seat 22 and the linkage rod 14 in the magnetic rod segment 16 leak out, at this time the plurality of magnetic segment assemblies 15 can be bent by themselves. Then the connecting rope 19 is passed through the folding limiting ring 18, so that part of the magnetic rod segments 16 in the plurality of magnetic rod assemblies 17 are magnetically adsorbed with each other, then the other telescopic electric clamp 31 is loosened, and the whole magnetic rod assembly 17 is released. Then the connecting rope 19 is continuously pulled out, a plurality of magnetic rod assemblies 17 can be pulled out at a time, and since the magnetic rod assembly 17 in the application is in a chain shape after stretching, the adjacent two magnetic rod assemblies 17 are forced to contact and adsorb together, like Figure 9As shown, this can pull out a plurality of magnetic rod components 17 at a time and also attract a plurality of magnetic rod components 17 to each other to form a plane, compared with the traditional columnar magnetic rod, the magnetic rod of the application will not roll, and it is also convenient to place and store multiple magnetic rods.

[0028] In summary, the magnetic force pressing device on the rotary screen printing machine is matched with the workbench 1, the two telescopic plates 3, the two tracks 2, the plurality of driving mechanisms 4, the plurality of electromagnets 27, the plurality of dismounting mechanisms 10 and the rotary screen cylinder mechanism 7. The original integral magnetic rod is set to be segmented, and the printing cylinder is slidingly arranged. In this way, multiple magnetic rods can be pulled out at a time, and multiple magnetic rods attract each other to form a plane. Compared with the original cylindrical magnetic rod which is prone to rolling, the magnetic rod structure greatly limits the rolling of the magnetic rod.
