In the production process, after the processing of the needle cylinder of the circular knitting machine is completed, each needle groove must be cleaned before the subsequent processes such as needle pieces and knitting needles can be installed.

[0003] For example, the patent with application number CN202020622458.1 discloses a cleaning device for the needle cylinder of a large circular knitting machine, which is used to clean the needle cylinder of the circular knitting machine, including a base, a circular cleaning table, a motor, a clamping mechanism, a cylinder, a connecting plate, a cleaning block, a water tank, a water pump and a nozzle. The cleaning table is pivotally connected to the top of the base, the motor is arranged at the bottom of the base and connected to the rotating shaft of the cleaning table, the clamping mechanism is arranged on the cleaning table and can clamp the needle cylinder on the cleaning table, the cylinder is vertically arranged on the base, the connecting plate is arranged on the output end of the cylinder, and the cleaning block is detachably rotatably connected to the connecting plate and corresponds to the inner and outer walls of the needle cylinder. The syringe is clamped on the cleaning table by a clamping mechanism, and the cleaning block is attached to the inner or outer wall of the syringe. Then, the driving motor drives the syringe to rotate, so that the inner or outer wall of the syringe can be quickly cleaned. Compared with traditional manual cleaning, the efficiency is greatly improved, and it is ready for use. However, this patent clamps the syringe by a clamping mechanism and then drives the syringe to rotate by a driving motor to cooperate with the cleaning block to achieve the purpose of cleaning. However, the slider and the clamping block are small, and the syringe is easy to fall out during high-speed rotation, causing damage to it.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below through the drawings and embodiments.

[0022] like Figure 1-4 As shown: a cleaning device for the needle cylinder of a large circular knitting machine, comprising a base 1, a cleaning table 2, a motor 3, and a needle cylinder 4. A clamping mechanism is provided on the cleaning table 2, and the clamping mechanism comprises a fixed box 9, a rotating rod 10, a first connecting rod 11, a fixed block 12, a limit plate 13, and a clamping plate 14. There are multiple clamping mechanisms, and multiple clamping mechanisms are circumferentially arranged on the cleaning table 2. The needle cylinder 4 is located between the two clamping plates 14. When cleaning, the needle cylinder 4 is placed between the clamping plates 14, and then the telescopic rod 15 is extended by the hydraulic rod 20, and the second cross bar of the rotating rod 10 is pushed outward. The first cross bar on the rotating rod 10 moves downward during rotation, driving the displacement sleeve 17 to move downward along the cylinder 16. At this time, the upper half of the rotating rod 10 rotates inward, pushing the clamping plate 14 and the limit plate 13 to move inward, so as to achieve clamping and limiting of the needle cylinder 4.

[0023] Two limit plates 13 are provided on the fixed box 9, and the inner sides of the two limit plates 13 are fixedly connected with clamping plates 14 respectively, and the other sides of the two limit plates 13 are fixedly connected with one end of the fixed plate 12. The height of the clamping plate 14 is the same as the height of the syringe 4. The inner wall where the clamping plate 14 contacts the syringe 4 can be covered with a layer of soft material to prevent slight damage to the syringe wall during cleaning.

[0024] The other end of the fixed plate 12 is fixedly connected to the first connecting rod 11, and the other single end of the first connecting rod 11 is rotatably connected to the rotating rod 10. The rotating rod 10 is in the shape of a "dagger" with two horizontal bars from top to bottom.

[0025] The end of the first cross bar on the rotating rod 10 is connected to the second connecting rod 19, and the other end of the second connecting rod 19 is rotatably connected to the extension column 18. The extension column 18 is fixed on both sides of the displacement sleeve 17. The displacement sleeve 17 is sleeved on the cylinder 16. The top of the cylinder 16 is fixedly connected to the inner wall of the fixed box 9. The displacement sleeve 17 moves up and down on the cylinder 16 as the rotating rod 10 rotates, and the up and down movement distance is less than the length of the cylinder 16 itself.

[0026] The end of the second cross bar on the left rotating rod 10 is connected to the telescopic rod 15, the other end of the telescopic rod 15 is connected to the end of the hydraulic rod 20, the other end of the hydraulic rod 20 is fixedly connected to the connecting rod fixing block 21, the connecting rod fixing block 21 is connected to the end of the second cross bar on the right rotating rod 10. When cleaning is completed, the telescopic column 15 is shortened to the initial state, and the second cross bar and the first cross bar of the rotating rod are restored to the initial state downward, the displacement sleeve 17 moves up on the cylinder 16, and the limit plate 13 and the clamping plate 14 are separated outward.
