When installing the brush roller, the brush roller is embedded in the connecting groove, and the baffle passes through the two mounting holes along its length direction so that the baffle contacts the brush roller. The locking block is moved along the length direction of the baffle so that the locking block is away from the baffle, driving the first spring to stretch and deform. After the locking block is away from the mounting hole, the locking block is rotated and embedded in the locking groove. At the same time, the spring is stretched and deformed, and under the influence of the elastic force of the first spring, the locking block is pressed against the locking groove, thereby driving the baffle to be stably connected in the connecting groove, so that the brush roller is stably connected in the connecting groove.

[0013] Optionally, a limiting rod is connected to the inner wall of the connecting groove along its length direction and away from one end of the connecting port, and the length direction of the limiting rod is consistent with the length direction of the connecting groove.

The length direction of the mounting block 310 is consistent with the radial direction of the rotating disk 300, and the mounting block 310 is provided with a connecting groove 320. The length direction of the connecting groove 320 is consistent with the length direction of the mounting block 310. The connecting groove 320 is provided with a connecting port 330 along its length and away from the center of the rotating disk 300. The inner wall of the connecting groove 320 along its length and away from the connecting port 330 is arranged in a circular arc surface, and the concave arc surface is arranged toward the bristle roller 200. When in use, the outer circumferential wall of the bristle roller 200 contacts the circular arc surface. The mounting block 310 is connected to an opening and closing assembly 400, which is used to open or close the connecting port 330 and lock the bristle roller 200 in the connecting groove 320. When replacing the brush roller 200, the opening and closing component 400 opens the connection port 330, so that the brush roller 200 can be taken out from the connection groove 320, and the brush roller 200 can be replaced in time, thereby avoiding the situation where impurities are stuck on the surface of the brush roller 200 and affecting the cleaning effect, improving the cleaning effect, reducing impurities on the surface of the guide belt, and improving the printing quality.

[0040] Reference Figure 1 and Figure 3 The frame 100 is rotatably connected to a first support roller 110 and a first pressure roller 120. Both the first support roller 110 and the first pressure roller 120 are used to contact the guide belt. The first support roller 110, the first pressure roller 120, and the bristle roller 200 are sequentially spaced along the conveying direction of the guide belt. The length of the first pressure roller 120 is consistent with the length of the bristle roller 200, and the length of the first support roller 110 is consistent with the length of the first pressure roller 120.

The length of the mounting rods 411 is consistent with the length of the baffle 410, and the mounting rods 411 are slidably connected to the mounting holes 350 along their length. The end of the mounting rods 411 away from the baffle 410 is connected to a partition 412. The partition 412 is arranged in a disc shape. The diameter of the partition 412 is larger than the inner diameter of the cylinder 424 and smaller than the width of the mounting hole 350.

[0048] Reference Figure 3 and Figure 7 Two locking members 420 are provided, one corresponding to each mounting rod 411. The locking members 420 are positioned between the partition 412 and the baffle 410. The locking member 420 comprises a locking block 421 and a first spring 422. The locking block 421 defines a rotation hole 423, the depth of which coincides with the length of the mounting rod 411. A cylinder 424 is rotatably coupled within the rotation hole 423. The central axis of the cylinder 424 coincides with the central axis of the rotation hole 423, and the outer circumferential wall of the cylinder 424 contacts the inner wall of the rotation hole 423.

A first magnetic block 361 is embedded in the inner wall of the locking groove 360 ​​near the connecting groove 320, and a second magnetic block 425 is embedded in the locking block 421 near the baffle 410. When the locking block 421 is embedded in the locking groove 360, the first magnetic block 361 and the second magnetic block 425 are attracted to each other, and the first spring 422 is stretched and deformed, and the baffle 410 contacts the bristle roller 200. When removing the bristle roller 200, move the locking block 421 along the length direction of the baffle 410 so that the locking block 421 is away from the locking groove 360, and rotate the locking block 421 to facilitate the locking block 421 to pass through the mounting hole 350, and then remove the baffle 410 from the connecting groove 320, thereby opening the connecting port 330, making it easier for the bristle roller 200 to be removed from the connecting groove 320 and easier to replace the bristle roller 200.

[0051] The implementation principle of the guide belt cleaning device of the rotary screen printing machine of the present application is as follows: when cleaning the guide belt, the guide belt passes through the first support roller, the first pressure roller 120, the bristle roller 200, the second pressure roller 160, and the second support roller 170 in sequence. Under the guidance of the first pressure roller 120 and the second pressure roller 160, the guide belt is pressed against the bristle roller 200. When replacing the bristle roller 200, the locking block 421 is pulled along the length direction of the baffle 410 and is moved away from the locking groove 360. After the locking block 421 is moved away from the locking groove 360, the locking block 421 is rotated so that the length direction of the locking block 421 is consistent with the width direction of the baffle 410, thereby facilitating the locking block 421 to pass through the mounting hole 350. The locking block 421 and the baffle 410 pass through the mounting hole 350 and move away from the mounting block 310, so that the connecting port 330 is opened, thereby facilitating the removal of the bristle roller 200 from the connecting groove 320.

[0052] When replacing the new brush roller 200, the brush roller 200 moves along the length direction of the connecting groove 320, and the brush roller 200 is embedded in the connecting groove 320. At the same time, the limiting rod 340 is embedded in the limiting groove 210, so that the brush roller 200 is stably connected to the connecting groove 320. The baffle 410 passes through the mounting hole 350 along the width direction of the connecting groove 320, so that two locking blocks 421 are respectively arranged on both sides of the connecting groove 320 along its width direction. When the baffle 410 is arranged in the connecting groove 320, the locking block 421 is moved along the length direction of the baffle 410 so that the locking block 421 is away from the mounting hole 350, and the first spring 422 is stretched and deformed. The locking block 421 is rotated so that the locking block 421 is embedded in the locking groove 360. Under the elastic influence of the first spring 422, the locking block 421 is tightly pressed against the locking groove 360, thereby stably connecting the baffle 410 to the connecting groove 320, and stably connecting the bristle roller 200 to the connecting groove 320. This facilitates the replacement of the bristle roller 200, minimizes the impact of impurities adhering to the surface of the bristle roller 200 on the cleaning effect, improves the cleaning effect, reduces impurities on the surface of the guide belt, and improves the printing quality.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
