[0031] Please refer to Figure 1 , Figure 2 , the present utility model provides a technical solution for the upper and lower cut blocks of an improved weft knitting large circular knitting machine, including a large circular knitting machine body, an upper needle disc and a lower needle cylinder arranged on the large circular knitting machine body, and further including:

[0032] Upper and lower cut blocks, the upper and lower cut blocks are composed of an upper disk cut - block 2 and a lower ring cut - block 1, and the structures between them are the same. Both include a triangular seat 11. A plurality of groups of sliding structures 12 are vertically opened at the rear side of the triangular seat 11. An adjusting structure 13 for adjustment is opened on the front end face of the triangular seat 11 corresponding to the sliding structure 12. A plurality of groups of positioning structures 14 for fixed installation are arranged at the front end of the triangular seat 11;

[0033] Among them, the upper disk cutting block 2 is installed on the upper needle plate, and the lower ring cutting block 1 is installed on one side of the lower needle cylinder.

[0034] Please refer to Figure 2 and Figure 5 , in order to adapt to more complex adjustment accuracy, the sliding structure 12 includes several groups of sliding grooves 121 that communicate up and down. A number of vertically sliding sliders 122 are movably arranged in the sliding grooves 121. The sliders 122 are arranged at equal intervals vertically along the sliding grooves 121. A receiving cavity 123 is provided on one side of the slider 122 facing the inner wall of the sliding groove 121.

[0035] Please refer to Figure 2 and Figure 5 , in order to accurately adjust the slider 122, the adjusting structure 13 includes several vertically spaced installation grooves 131. A scale 132 for adjusting the vertical sliding of the corresponding slider 122 is embedded in the installation groove 131. The scale 132 is in threaded cooperation with the installation groove 131. A screw is horizontally embedded in the scale 132. Internal threads for threaded cooperation with the screw are provided on the inner wall of the installation groove 131. A wavy wire groove is provided along the circumference on the back of the scale 132. The installation groove 131 communicates with the sliding groove 121. The scale 132 corresponds to the slider 122 and shares the same slider track. The structure is simple and the installation is convenient, achieving independent adjustment and not increasing additional space occupation.

[0036] Please refer to Figure 2 , in order to fix the triangular seat 11, the positioning structure 14 includes a positioning hole 141 and a positioning groove 142, and the positioning hole 141 communicates with the positioning groove 142.

[0037] Please refer to Figure 2 , Figure 5 , in order to limit the lifting movement of the slider 122, a lifting spring 124 for realizing lifting and resetting is embedded in the receiving cavity 123. Limit strips 125 for restricting the movement of the slider 122 are provided at both the upper and lower ends of the slider 122. Necessary resistance is provided during the adjustment process, friction is reduced, positioning accuracy is improved, and structural stability is enhanced, so as to ensure that the circular knitting machine can perform high-precision knitting operations. A number of first positioning grooves 126 corresponding to the limit strips 125 are horizontally opened on the inner side of the sliding groove 121. The limit strips 125 are embedded in the first positioning grooves 126 to limit the lifting movement of the slider 122.

[0038] Please refer to Figure 5, in order to lift and reset the slider 122, the lifting spring 124 is embedded in the accommodating cavity 123, one end abuts against the upper wall of the accommodating cavity 123, and the other end abuts against the limiting strip 125. When the slider 122 moves downward, the limiting strip 125 can limit its movement. When the slider 122 moves upward, the lifting spring 124 can provide a restoring elastic force to make it move upward and reset faster.

[0039] Please refer to Figure 3 , Figure 4 , in order to improve the rotation accuracy and stability, a second positioning groove 133 is provided inside the installation groove 131. A ball spring 134 and a ball 135 are embedded in the second positioning groove 133. The ball 135 is placed at the front end of the ball spring 134. When the adjustment scale 132 is rotated clockwise or counterclockwise, the ball 135 will be stuck in the wavy wire groove behind the scale 132. For each rotation of one grid, the ball 135 jumps from one wavy wire groove to another wavy wire groove. When adjusting, the ball spring 134 can reset the ball 135 (when adjusting, the ball spring 134 is compressed into the second positioning groove 133 under extrusion. Continue to rotate. When the ball spring 134 is again aligned with the center of the wavy wire groove, it is pushed by the ball spring 134 to reset and be stuck in the wavy wire groove). When the ball 135 adjusts and rebounds, there will be a sound feedback to indicate the accuracy of the current adjustment of the scale 132.

[0040] Please refer to Figure 6 , in order to meet the requirements for knitting complex patterns, the number of scales 132 on the upper disk segment 2 is four, and the number of scales 132 on the lower ring segment 1 is six. By adding two more scales 132 on the triangular base 11, the positions of multiple triangles can be adjusted simultaneously, improving the selectivity of the triangle arrangement and meeting the requirements for knitting complex patterns.

[0041] Please refer to Figure 6 , in order to precisely control the movement of the knitting needles, the upper disk segment 2 includes a triangular base 11. A set of sliding structures 12 and a set of adjusting structures 13 for adjusting the sliding structures 12 are specifically provided on the triangular base 11. A set of positioning structures 14 for fixed installation are provided at the bottom of the triangular base 11. Among them, the sliding structure 12 specifically includes a set of vertically arranged sliding grooves 121. Four sliders 122 are movably arranged on the sliding grooves 121. The installation groove 131 corresponds to the scale 132 and the slider 122 installed therein.

[0042] Embodiment 2

[0043] For the sake of simplicity of description, the parts that are the same as those in Embodiment 1 will not be described again. Now, the structures different from those in Embodiment 1 of the present utility model will be mainly described. The difference between Embodiment 2 and Embodiment 1 lies only in the upper disk segment 2.

[0044] Please refer toFigure 7 In this embodiment, the upper plate cutting block 2 includes a triangular seat 11. Specifically, two sets of sliding structures 12 and two sets of adjusting structures 13 for adjusting the sliding structures 12 are provided on the triangular seat 11. A set of positioning structures 14 for fixed installation are provided at the bottom of the triangular seat 11. Among them, the sliding structure 12 specifically includes two sets of sliding grooves 121 arranged vertically in parallel. Four sliders 122 are respectively movably provided on the sliding grooves 121. The installation groove 131 corresponds to the scale 132 and the slider 122 installed therein.

[0045] The operator drives the corresponding slider 122 for fine adjustment by rotating the scale 132 in the installation groove 131 (there are four on the upper plate cutting block 2 and six on the lower ring cutting block), so that each slider 122 moves up and down in the sliding groove 121. During the adjustment process, the lifting spring 124 forms a reset function for lifting in the accommodating cavity 123. The nested structure of the limiting strip 125 and the second positioning groove 133 ensures the stability of the vertical movement track of the slider 122 and enables the sliders 122 to be independent of each other without interference. The ball spring 134 improves the adjustment stability and accuracy through the rolling of the balls 135 with the scale 132. Through this multi-level independent adjustment of the upper needle plate and the lower needle cylinder, the butt height of the knitting needles and the timing of needle retraction can be set differently. Six different density coil combinations can be knitted through six adjustment points on the lower ring, and the special structures such as tuck stitches and floats can be accurately controlled in cooperation with the four adjustment points on the upper plate. Finally, dozens of permutations and combinations of the movement tracks of the knitting needles are formed. This adjustment mechanism enables the upper and lower cutting blocks to flexibly adjust the position and angle of the cams according to different pattern designs, so as to achieve precise control of the knitting needles and meet the knitting requirements of complex patterns.
