Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-6 This utility model provides a technical solution for a one-bath dyeing equipment.
[0029] A one-bath staining apparatus, comprising:
[0030] The dyeing box 1 has an upward-facing dyeing chamber 2. The dyeing chamber 2 has a dyeing inlet 3 and a dyeing outlet 4 at both ends. Several guide rollers 5 are rotatably connected inside the dyeing chamber 2.
[0031] Vertical rod 6 is fixed inside the dyeing chamber 2, and upper fixing plate 7 and lower fixing plate 8 are fixed at both ends of vertical rod 6 respectively;
[0032] The first vertical shaft 9 is rotatably connected between the upper fixed plate 7 and the lower fixed plate 8, and a drive pulley 10 is fixed on the first vertical shaft 9.
[0033] The second vertical shaft 11 is rotatably connected to the lower fixed plate 8. A driven pulley 12 is fixed on the second vertical shaft 11, and a stirring blade 13 is fixed on the second vertical shaft 11.
[0034] Connecting belt 14 connects the drive pulley 10 and the driven pulley 12;
[0035] The drive motor 15 is used to drive the first vertical shaft 9 to rotate. An outer bracket 16 is fixed on the dyeing box 1, and the drive motor 15 is fixed on the outer bracket 16. The drive motor 15 is located above the first vertical shaft 9, and the rotating shaft of the drive motor 15 is connected to the first vertical shaft 9.
[0036] The fabric enters the dyeing chamber 2 through the dyeing inlet 3, and then exits through the dyeing outlet 4 via the guide roller 5. The drive motor 15 drives the first vertical shaft 9 to rotate, which in turn drives the drive pulley 10 to rotate. The drive pulley 10 drives the second vertical shaft 11 to rotate through the connecting belt 14 and the driven pulley 12, which in turn drives the stirring blade 13 to rotate, thus ensuring uniform mixing of the dye liquor. Since the drive motor 15 is located above the first vertical shaft 9, the dye liquor will not come into contact with the drive motor 15, preventing leakage of dye liquor into the drive motor 15.
[0037] Below is one method of fixing the vertical rod 6, such as... Figure 6 As shown, a connecting rod 25 is fixed to the vertical rod 6. The connecting rod 25 has a downward-facing connecting groove 26. The side wall of the dyeing box 1 is inserted into the connecting groove 26. The side wall of the connecting groove 26 has several threaded holes, and fastening bolts 27 are threaded into the threaded holes. By tightening the fastening bolts 27, the end of the fastening bolt 27 abuts against the outer wall of the dyeing box 1, thereby fixing the vertical rod 6 to the dyeing box 1 together.
[0038] The following is one connection method between the drive motor 15 and the first vertical axis 9, such as... Figure 5 As shown, an upper fixing block 17 is fixed to the upper end of the first vertical axis 9. The upper fixing block 17 is provided with an upper insertion groove 18 with the opening facing upward. An insertion rod 19 is inserted into the insertion groove. A limit spring 20 is installed in the insertion groove. The limit spring 20 is located between the bottom surface of the insertion groove and the insertion rod 19. A connecting block 21 is fixed on the rotating shaft of the drive motor 15. The connecting block 21 is provided with a limit groove 22 for the insertion rod 19 to be inserted. The cross sections of the insertion rod 19 and the limit groove 22 are both rectangular.
[0039] When the drive motor 15 needs to drive the first vertical shaft 9 to rotate normally, the upper end of the plug rod 19 is inserted into the limiting groove 22. The drive motor 15 drives the connecting block 21 to rotate, and the connecting block 21 drives the first vertical shaft 9 to rotate through the plug rod 19. When it is necessary to remove the stirring blade 13 for cleaning, first loosen the fastening bolt 27, and then pull down the plug rod 19 so that the upper end of the plug rod 19 moves out of the limiting groove 22. At this time, the stirring blade 13 and other parts can be removed from the dyeing chamber 2 for cleaning, which is very convenient.
[0040] like Figure 5 As shown, a side groove 23 is provided on the side wall of the insertion slot, and a pressing rod 24 extending out of the side groove 23 is fixed on the insertion rod 19. By pressing down the pressing rod 24, the insertion rod 19 can be moved downward, making it more convenient to move the insertion rod 19 downward.
[0041] like Figure 5 As shown, the plug rod 19 is provided with a downward-facing mounting groove 28, and one end of the limiting spring 20 is plugged into the mounting groove 28 to limit the position of the limiting spring 20.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
