[0026] An automatic homogenizing device in a rotary screen printing machine comprises a connecting frame body 1, both ends of the connecting frame body 1 are slidably connected with a moving plate 2, a homogenizing assembly 3 is arranged inside the moving plate 2 and at one end away from the connecting frame body 1, a connecting frame 4 is arranged at the bottom of the connecting frame body 1 and between two groups of moving plates 2, a driving rack 5 is arranged at one end of the moving plate 2 close to the connecting frame 4, and a first driving gear 6 is rotatably connected inside the connecting frame 4;

[0027] The homogenizing component 3 is used to evenly stir the color paste inside the round screen cylinder.

[0028] Furthermore, the homogenization assembly 3 is composed of a fixed frame 7, an engaging disk 8, a second driving gear 9, a connecting rod 10 and a stirring rod 11. The fixed frame 7 is located at the end of the movable plate 2 away from the connecting frame body 1, the engaging disk 8 is rotatably connected to the inside of the fixed frame 7, and two groups of second driving gears 9 are respectively engaged and connected to the two ends of the engaging disk 8. The connecting rod 10 is fixedly connected to the outside of the second driving gear 9 and extends to the outside of the fixed frame 7. The stirring rod 11 is fixedly connected to the end of the connecting rod 10 away from the fixed frame 7. The homogenization assembly 3 can be used to evenly stir the color paste inside the circular mesh cylinder, thereby preventing the color paste from being unevenly stored in the length direction of the circular mesh cylinder. The color printed on the fabric is easily formed into uneven color strips at the junction of the pattern, which is commonly known as "white strips", affecting product quality.

[0029] Among them, a driving motor is provided inside the fixed frame 7, and the driving end of the driving motor is fixedly connected to the meshing disk 8. When the driving motor is started, the meshing disk 8 is driven to rotate, so that the second driving gear 9 meshingly connected thereto can rotate, driving the connecting rod 10 to rotate, thereby enabling the stirring rod 11 to rotate.

[0030] Secondly, the fixed frame 7 is connected to the connecting rod 10 through the fixed block 12. The connecting rod 10 and the fixed block 12 are rotationally connected. The connecting rod 10 and the fixed block 12 are rotationally connected so that the connecting rod 10 can be connected to the fixed frame 7.

[0035] Furthermore, a movable groove 19 is opened inside the connecting frame body 1, and the internal structure size of the movable groove 19 is designed to correspond to the external structure size of the driving block 18. The driving block 18 passes through the movable groove 19 and is fixedly connected to the movable plate 2. The driving block 18 is fixedly connected to the movable plate 2. When the driving block 18 is displaced, it can drive the movable plate 2 to be displaced, so that the driving rack 5 can be displaced, and the first driving gear 6 can be rotated, so that another group of driving racks 5 can be displaced, driving another group of movable plates 2 to be displaced, so that the two groups of movable plates 2 can be displaced, driving the stirring rod 11 to be displaced.

[0036] In this embodiment, the implementation scenario is specifically as follows: in actual use, the telescopic cylinder 16 is started to drive the moving rod 17 to move, so that the driving block 18 can move, and when the driving block 18 moves, it can drive the moving plate 2 to move, so that the driving rack 5 can move, and drive the first driving gear 6 to rotate, so that another set of driving racks 5 can move, and drive another set of moving plates 2 to move, so that the two sets of moving plates 2 can move, drive the stirring rod 11 to move back and forth, start the driving motor, and drive the meshing disk 8 It rotates so that the second driving gear 9 meshing with it can rotate, driving the connecting rod 10 to rotate, thereby allowing the stirring rod 11 to rotate. The color paste inside the round mesh cylinder can be evenly stirred through the homogenizing component 3, thereby preventing the color paste from being stored unevenly in the length direction of the round mesh cylinder. The color printed on the fabric can easily form uneven color strips at the junction of the pattern, which are commonly known as "white strips", affecting the product quality. Compared with the existing homogenizing device, the utility model can improve the overall practicality of the homogenizing device through design.
