[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0017] like Figure 1-Figure 2As shown, a needle cylinder cleaning device for a large circular knitting machine includes a chassis 32, a workbench 1 is arranged on the upper part of the chassis 32, a driving motor 3 is arranged inside the chassis 32, a supporting mechanism 2 is drivingly connected to the driving motor 3, and the supporting mechanism 2 includes a rotating disk 4. The upper end of the motor shaft of the driving motor 3 passes through the workbench 1 and is connected to the bottom of the rotating disk 4. A plurality of fixed frames 5 are evenly distributed on the upper part of the rotating disk 4, and a driving mechanism 6 is fixedly installed on the fixed frame 5. The driving mechanism 6 is drivingly connected to a moving block 9, and the end of the moving block 9 away from the driving mechanism 6 is connected to a supporting block 7, and a positioning block 8 is connected to the upper part of the supporting block 7. According to the diameter of the needle cylinder to be cleaned, the position of the supporting block 7 is pre-adjusted to a suitable position so that the needle cylinder can be placed on the supporting block 7 for support. The driving mechanism 6 then drives the supporting block 7 to move outward, so that the positioning block 8 abuts against the inner side of the needle cylinder, thereby completing the positioning and fixing of the needle cylinder.

[0018] At least three fixed frames 5 are provided, and when each driving mechanism 6 synchronously drives the moving block 9 to move outward, it can play a self-centering role to position the placed syringe.

[0019] The workbench 1 is provided with a mounting frame 12 on the top of the mounting frame 12. A screw motor 33 is provided on the top of the mounting frame 12. The screw motor 33 is connected to the screw 23. The screw nut 24 is provided on the screw 23. The screw nut 24 is connected to a support plate 25 on the side close to the support mechanism 2. A driving mechanism 26 is provided on the bottom of the support plate 25. The driving mechanism 26 is connected to the moving block 27. A nozzle 21 is provided on the bottom of the moving block 27. A mounting seat 28 is connected on the bottom of the moving block 27. The nozzle 21 is installed on the mounting seat 28. The nozzle 21 is arranged toward the syringe and tilted downward, so that the sprayed liquid tilts downward, which can better clean the needle groove of the syringe and remove the dirt in the needle groove. A liquid supply box 15 is provided in the chassis 32. A liquid supply pump 19 is provided on the top of the liquid supply box 15. A liquid supply pipe 20 is connected to the liquid supply pump 19. The other end of the liquid supply pipe 20 is connected to the nozzle 21. The upper portion of the liquid supply box 15 is also connected to a liquid replenishing tube 22 . When the liquid in the liquid supply box 15 is less, liquid can be replenished into the liquid supply box 15 through the liquid replenishing tube 22 .

[0020] A notch 13 is provided on the workbench 1, and a funnel 10 is provided in the notch 13. The funnel 10 is located below the contact between the liquid sprayed from the nozzle 21 and the syringe, so as to catch the liquid flowing down after flushing. A baffle 11 is provided on the upper part of the workbench 1 at the outer periphery of the upper opening of the funnel 10, and the baffle 11 can block the liquid, so as to better collect the liquid. A liquid collecting box 14 is provided in the chassis 32, and the lower end of the funnel 10 is connected to the liquid collecting box 14 through a pipeline, and the liquid flows down along the liquid collecting box 14 and falls into the liquid collecting box 14 below for collection.

[0021] In order to better rinse the syringe, the nozzle 21 needs to be raised and lowered and moved laterally to get close to the syringe. A telescopic section 31 is provided on the liquid supply tube 20, which can be telescoped when the nozzle 21 moves, thereby preventing the liquid supply tube 20 from being damaged due to folding.

[0022] A liquid pump 16 is provided on the side of the liquid supply tank 15, and a liquid extraction pipe 17 is connected to the liquid pump 16. The other end of the liquid extraction pipe 17 is connected to the lower side of the liquid collection tank 14, and a filter 18 is provided at the connection between the liquid extraction pipe 17 and the liquid collection tank 14. The liquid extraction pump 16 extracts the liquid in the liquid collection tank 14 into the liquid supply tank 15 through the liquid extraction pipe 17 for reuse. By providing the filter 18, the liquid in the liquid collection tank 14 can be filtered to intercept impurities.

[0023] A fixing sleeve 1 29 is provided at the lower part of the moving block 27, and a fixing sleeve 2 30 is provided on the workbench 1. The liquid supply pipe 20 passes through the fixing sleeve 1 29 and the fixing sleeve 2 30. The fixing sleeve 1 29 and the fixing sleeve 2 30 fix the liquid supply pipe 20 to prevent the liquid supply pipe 20 from shaking.

[0024] Among them, the driving mechanism 1 6 and the driving mechanism 2 26 are cylinders or hydraulic cylinders.
