Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-Figure 11 , the utility model provides a technical solution for a dye mixing device.

[0034] A dye mixing device, comprising:

[0035] A stirring barrel 1, wherein a stirring chamber 2 is provided in the stirring barrel 1;

[0036] A stirring shaft 3, the stirring shaft 3 is rotatably connected to the upper side wall of the stirring barrel 1, a plurality of stirring paddles 4 are arranged on the stirring shaft 3, the stirring paddles 4 are located in the stirring chamber 2, two fixed cross bars 5 are fixed on the stirring paddles 4, and the two fixed cross bars 5 are both provided with telescopic grooves 6, and the two telescopic grooves 6 are connected;

[0037] The scraper rod 9 assembly includes two telescopic rods 7, a connecting spring 8 and a limiting structure. The two telescopic rods 7 are respectively plugged into the two telescopic grooves 6. The end of the telescopic rod 7 extending out of the telescopic groove 6 is fixed with a scraper rod 9. The adjacent ends of the two telescopic rods 7 are provided with grooves 10. The two ends of the connecting spring 8 are respectively plugged into the two grooves 10. The upper end of the stirring shaft 3 is provided with a connecting groove 11, which is connected to the telescopic groove 6. A vertical rod 12 is fixed on the adjacent ends of the two telescopic rods 7. The vertical rod 12 is located in the connecting groove 11. The limiting structure includes an unlocked state and a limited state. In the unlocked state, the scraper rod 9 abuts against the inner wall of the stirring chamber 2. In the limited state, the scraper rod 9 leaves the side wall of the stirring chamber 2.

[0038] The driving device is used to drive the stirring shaft 3 to rotate.

[0039] During normal stirring, the limiting structure is in a limiting state, at which time the scraper rod 9 leaves the side wall of the stirring chamber 2, the connecting spring 8 is in a compressed state, the driving device drives the stirring shaft 3 to rotate, and the stirring paddle 4 on the stirring shaft 3 stirs. At this time, since the scraper rod 9 does not touch the inner wall of the stirring chamber 2, no wear will occur. When the inner wall of the stirring chamber 2 needs to be cleaned, the limiting structure is switched to an unlocked state, at which time the connecting spring 8 rebounds, driving the telescopic rod 7 to move outward, the scraper rod 9 abuts against the inner wall of the stirring chamber 2, and then the stirring shaft 3 rotates, and the scraper rod 9 can clean the dye liquid stuck in the stirring chamber 2. During the cleaning process, cleaning liquid can be added to the stirring chamber 2 to increase the cleaning effect.

[0040] The following is an implementation method of the limiting structure. Figure 5 As shown, the limiting structure includes two limiting bolts 13, and the two limiting bolts 13 correspond to the two vertical rods 12 one by one. Two internal threaded holes 14 are provided on the side wall of the connecting groove 11, and the two internal threaded holes 14 are respectively located on the outside of the two vertical rods 12. The two limiting bolts 13 are respectively threadedly connected with the two internal threaded holes 14, and the ends of the limiting bolts 13 abut against the outer side surfaces of the corresponding vertical rods 12. During the process of switching from the unlocked state to the limited state, the limiting bolts 13 drive the corresponding vertical rods 12 to move toward the middle of the connecting groove 11, and the scraper rod 9 will gradually leave the inner wall of the stirring chamber 2 during the movement. When the limiting bolts 13 are rotated in the opposite direction, the vertical rod 12 will move away from the middle of the connecting groove 11, and the connecting spring 8 will drive the telescopic rod 7 to move outward, so that the scraper rod 9 abuts against the inner wall of the stirring chamber 2. The position of the scraper rod 9 can be adjusted by simply rotating the limiting bolts 13, and the adjustment is very convenient.

[0041] like Figure 5 As shown, a fastening nut 15 is threadedly connected to the limit bolt 13, and a plane 16 corresponding to the fastening nut 15 is provided on the outer wall of the stirring shaft 3. When the limit bolt 13 is rotated to a desired position, the fastening nut 15 is rotated to make the fastening nut 15 collide with the plane 16, and the fastening nut 15 can play a role in fastening the limit bolt 13 to prevent the limit bolt 13 from rotating.

[0042] The following is another embodiment of the limiting structure. Figure 7-Figure 11As shown, the limiting structure includes two extrusion rods 17, a cross bar 18 fixed between the two extrusion rods 17 and a connecting bolt 19 passing through the cross bar 18. Two slots 20 are provided at the upper end of the connecting groove 11. The two slots 20 are located on opposite sides of the connecting groove 11. The two slots 20 are located on both sides of the two vertical rods 12. The two extrusion rods 17 are plugged into the two slots 20. The two extrusion rods 17 correspond to the two vertical rods 12 one by one. A first inclined surface 21 is provided at the upper end of the vertical rod 12. A second inclined surface 22 that fits the first inclined surface 21 is provided on the extrusion rod 17. A threaded block 23 is fixed in the connecting groove 11. A connecting threaded hole 24 is provided on the threaded block 23. The connecting bolt 19 is threadedly connected to the connecting threaded hole 24. During the process of converting the unlocking state to the limiting state, the connecting bolt 19 is gradually screwed into the connecting threaded hole 24.

[0043] When the connecting bolt 19 is gradually screwed into the connecting threaded hole 24, the cross bar 18 can be driven to move toward the connecting groove 11, and the second inclined surface 22 on the extrusion rod 17 squeezes the first inclined surface 21, driving the vertical rod 12 to move toward the middle of the connecting groove 11, thereby driving the scraper rod 9 to leave the inner wall of the stirring chamber 2, and the limiting structure is in a limited state. Reverse rotation of the connecting bolt 19 can drive the scraper rod 9 to abut against the inner wall of the stirring chamber 2, and the limiting structure is in an unlocked state.
