[0020] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0021] See also Figure 1 and Figure 2The utility model provides a needle cylinder fixing assembly for a large circular knitting machine, comprising a mounting plate 1, on which a bolt hole 2 is opened. The mounting plate 1 is placed on a supporting platform of the large circular knitting machine, and then the bolt is passed through the bolt hole 2 to connect with the supporting platform to fix the mounting plate 1 on the supporting platform. A pressing sleeve 3 is provided on the mounting plate 1, and the pressing sleeve 3 can push and fix the needle cylinder fixed inside, thereby fixing the needle cylinder. A reinforcement structure 4 is provided on the surface of the pressing sleeve 3.

[0022] See also Figure 1 、 Figure 3 and Figure 4 The utility model provides a needle cylinder fixing assembly for a large circular knitting machine. The reinforcement structure 4 includes a fixing block 41, which is welded to the outer surface of the pressing sleeve 3 and the top surface of the mounting plate 1. The fixing block 41 is provided with a screw 42 in a vertical state, and the screw 42 is rotatably connected to the fixing block 41. A knob 43 is integrally formed on the top of the screw 42, and the knob 43 protrudes from the top surface of the fixing block 41.

[0023] The screw rod 42 is provided with threads at both ends, and the threads at both ends are symmetrical. At the same time, the screw rod 42 is equipped with thread blocks 44 at both ends, which are threadedly connected to the threads at both ends. When the screw rod 42 is rotated, the thread blocks 44 at both ends will slide up and down together in a vertical state. The thread blocks 44 at both ends have the same structure and are symmetrical. Two top plates 45 are integrally formed on the surface of the thread blocks 44.

[0024] The interior of the pressing sleeve 3 is equipped with a push frame 46 that is connected in a horizontal sliding manner, and a filling pad 471 is installed in the push frame 46, and a pressure plate 47 that is connected in a horizontal sliding manner is installed in the push frame 46. The filling pad 471 is located between the push frame 46 and the pressure plate 47. The push frame 46 is in contact with the top plate 45. When the top plate 45 slides, it slides along the surface of the push frame 46, and a positioning frame 461 is integrally formed on the surface of the push frame 46 that contacts the top plate 45. The top plate 45 is located in the positioning frame 461. The positioning frame 461 can limit the top plate 45, thereby improving the sliding stability of the top plate 45, and the surface of the positioning frame 461 is in contact with the surface of the threaded block 44 to support the push frame 46 and avoid skewness. The number of positioning frames 461 is the same as the number of the top plate 45.

[0025] After the pressing sleeve 3 fixes the needle cylinder, the knob 43 is turned to drive the screw 42 to rotate. While the screw 42 rotates, the threaded block 44 moves along the surface of the screw 42, and the threaded block 44 slides along the inner wall of the fixed block 41. When the threaded block 44 slides, the top plate 45 slides therewith and slides along the surface of the push frame 46. At the same time, the top plate 45 pushes the push frame 46, so that the push frame 46 slides horizontally along the inner wall of the pressing sleeve 3, and then pushes the pressing plate 47 to make the pressing plate 47 fit against the surface of the needle cylinder. Under continuous pushing, the needle cylinder in the pressing sleeve 3 is reinforced. Under the continuous pushing of the pressing plate 47, the filling pad 471 will be compressed and generate elastic force. Under the action of the elastic force, the pressing plate 47 will fit more closely against the surface of the needle cylinder, so as to achieve reinforcement and fixation of the needle cylinder after it is fixed, making it less likely to vibrate during work, thereby improving the stability of the needle cylinder.
