DETAILED DESCRIPTION

[0020] The following is combined with Figure 1 -Attached Figure 5 The embodiments of the present utility model are described in detail.

[0021] A large circular knitting machine turntable, comprising a turntable body 1, a plurality of wear-resistant blocks 2 are arranged on the turntable body 1, a vertical channel 6 is opened on the turntable body 1 in the vertical direction, a mounting block 4 is arranged in the vertical channel 6, the mounting block 4 can slide up and down and is arranged in the vertical channel 6, a mounting frame 7 is arranged on the upper part of the mounting block 4, the wear-resistant block 2 is installed in the mounting frame 7, the height of the upper end of the wear-resistant block 2 is higher than the height of the upper end of the mounting frame 7, an opening 5 for exposing the wear-resistant block 2 and the mounting frame 7 is opened at the upper end of the vertical channel 6, and a through hole 1 is opened on the mounting block 4 at a position below the wear-resistant block 2 8, the through hole 18 is located within the range enclosed by the mounting frame 7, a rotating seat 15 is installed at a position below the vertical channel 6 in the turntable body 1, an adjusting screw 16 is connected to the rotating seat 15 through an internal thread, a push block 14 is connected to the upper portion of the adjusting screw 16, a through hole 3 17 is opened inside the adjusting screw 16 along its axial direction, a rotating seat 2 19 is arranged inside the through hole 3 17, an adjusting screw 2 20 is connected to the rotating seat 2 19 through an internal thread, the adjusting screw 2 20 is located directly below the through hole 18, and the diameter of the adjusting screw 20 is slightly smaller than the diameter of the through hole 18.

[0022] By rotating the adjusting screw 16 in the rotating seat 15, the adjusting screw 16 drives the push block 14 to rise. The push block 14 moves upward against the mounting block 4, so that the wear-resistant block 2 and the mounting frame 7 are exposed from the opening 5. The size of the mounting block 4 is adapted to the size of the vertical channel 6, thereby guiding the lifting and lowering of the mounting block 4 to ensure that the opening 5 is lifted and lowered vertically. The cross-sectional size of the opening 5 is smaller than the cross-sectional size of the vertical channel 6, and the mounting block 4 will be stuck in the vertical channel 6, and only the wear-resistant block 2 and the mounting frame 7 are exposed from the opening 5. After the wear-resistant block 2 is worn during use, the adjusting screw 20 can be rotated to make the adjusting screw 20 rise in the adjusting screw 16, and the upper end of the adjusting screw 20 passes through the through hole 18 and is pressed under the wear-resistant block 2, so that the wear-resistant block 2 is lifted a certain distance in the mounting frame 7 to compensate for the reduced height of the wear-resistant block 2 after wear.

[0023] Preferably, the turntable body 1 is provided with a transverse channel 3 in the horizontal direction, the transverse channel 3 is connected with the vertical channel 6, the transverse channel 3 is provided on the peripheral side of the turntable body 1, and a driving mechanism capable of driving the wear-resistant block 2 to move along the transverse channel 3 is provided in the transverse channel 3. By providing the transverse channel 3 connected with the vertical channel 6 and providing a driving mechanism to move the mounting block 4 and the wear-resistant block 2, the mounting block 4 and the wear-resistant block 2 can be conveniently replaced.

[0024] Preferably, the driving mechanism includes a moving rod 25, the inner end of which is connected to an insertion rod 13, the size of the insertion rod 13 is smaller than that of the moving rod 25, the lower part of the mounting block 4 is connected to a linkage plate 9, the linkage plate 9 is provided with a through hole 11 for inserting the insertion rod 13, the lower part of the insertion rod 13 is provided with a mounting groove 22, a clamping block 23 is arranged in the mounting groove 22, a spring 24 is connected to the top of the clamping block 23, and the other end of the spring 24 is connected to the top wall of the mounting groove 22.

[0025] When the wear-resistant block 2 is pushed inward, the insertion rod 13 is inserted into the second through hole 11, and the moving rod 25 is pressed against the linkage plate 9. During the insertion process, the block 23 on the insertion rod 13 is retracted into the installation groove 22. After the block 23 passes through the second through hole 11, the block 23 is re-popped out under the action of the spring 24, and the moving rod 25 is pushed into the vertical channel 6, thereby driving the linkage plate 9 to move inward. When the push block 14 moves upward under the action of the adjusting screw 16, it will press against the block 23 and push it back into the installation groove 22. At this time, the insertion rod 13 can be pulled out of the second through hole 11 without affecting the subsequent lifting of the installation block 4 by the push block 14.

[0026] After the push block 14 drives the mounting block 4 to descend to the bottom of the vertical channel 6, the moving rod 25 is pushed again to insert the insertion rod 13 into the second through hole 11, and then the moving rod 25 is pulled outward, and the clamping block 23 acts on the linkage plate 9 to drive the mounting block 4 and the wear-resistant block 2 to move outward, thereby completing the replacement.

[0027] Preferably, an introduction slope 12 is provided on the side of the through hole 11 close to the movable rod 25, and the introduction slope 12 is inclined downward and outward. The setting of the introduction slope 12 is conducive to squeezing the block 23 when the insertion rod 13 is inserted into the through hole 11, so that the block 23 can be better retracted into the installation groove 22, thereby allowing the insertion rod 13 to be smoothly inserted into the through hole 11.

[0028] Preferably, the lower part of the outer periphery of the adjusting screw 16 is connected with a limiting ring 18. The setting of the limiting ring 18 is conducive to the rotation of the adjusting screw 16, and can cooperate with the rotating seat 15 to limit the rise of the adjusting screw 16, thereby limiting the rising position of the adjusting screw 16.

[0029] Preferably, the lower part of the outer periphery of the adjusting screw 20 is connected with a limiting ring 21. The setting of the limiting ring 21 can facilitate the rotation of the adjusting screw 20. At the same time, the setting of the limiting ring 21 can limit the rising height of the adjusting screw 20 in the adjusting screw 1 16, thereby preventing the adjusting screw 20 from pushing the wear-resistant block 2 out of the mounting frame 7 when lifting the wear-resistant block 2.

[0030] Preferably, the front and rear sides of the linkage plate 9 are connected with side plates 26 , and the side plates 26 are arranged to fit the front and rear side walls of the transverse channel 3 , so that the mounting block 4 will not deviate when moving along the transverse channel 3 .

[0031] Preferably, in order to prevent the installation block 4 from getting stuck at the upper end of the vertical channel 6 and being unable to synchronously descend with the push block 14, a clamping strip 10 is connected to the lower part of the inner side of the side plate 26, and the distance between the front and rear clamping strips 10 is greater than the diameter of the adjusting screw 16, so that the installation block 4 will not collide with the adjusting screw 16 when it moves from the vertical channel 6 to the vertical channel 6. The push block 14 is circular, and the distance between the front and rear clamping strips 10 is less than the diameter of the push block 14. When the adjusting screw 16 is rotated to move the push block 14 downward, the lower end of the push block 14 abuts against the upper part of the clamping strip 10, thereby driving the installation block 4 to descend through the clamping strip 10.

[0032] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
