[0035] Refer to Figures 1-4, A circular knitting machine needle selection mechanism, including an L-shaped adjustment base 1, an adjustment surface 101 is arranged on the inner side of the upper end of the L-shaped adjustment base 1, a T-shaped groove 102 is opened in the middle and one side of the L-shaped adjustment base 1, the bottom of the sliding block 103 is slidably connected to the inside of the T-shaped groove 102, and both sides of the sliding block 103 are slidably connected to the upper surface of the middle part of the L-shaped adjustment base 1, an adjustment mechanism 2, including a first fixing block 201 fixedly connected to the upper surface of the L-shaped adjustment base 1 near one side of the adjustment surface 101, a circular through hole 202 is penetrated through the middle of the first fixing block 201, the middle of the sliding column 203 is slidably connected to the inside of the circular through hole 202, both ends of the sliding column 203 are respectively fixedly connected to one side of the moving block 207 and one side of the square block 206, the bottom of the second fixing block 204 is fixedly connected to the upper surface of the L-shaped adjustment base 1 near one side of the first fixing block 201, a square hole 205 is penetrated through the middle of the second fixing block 204, the middle outer wall of the square block 206 is slidably connected to the inside of the square hole 205, one end of a first spring 208 is respectively fixedly connected to one side of the moving block 207 and one side of the first fixing block 201, and the other end of the first spring 208 is respectively fixedly connected to the other side of the first fixing block 201 and one side of the second fixing block 204.

[0036] The bottom of the U-shaped block 209 is fixedly connected to the middle part and one side of the surface of the sliding block 103, the U-shaped block 209 is used for clamping and fixing the needle selector, one side of two extension blocks 210 is fixedly connected to both sides of the sliding block 103, a first stepped hole 211 is symmetrically penetrated through both sides of the extension block 210, a threaded groove 212 is opened on the inner wall of the upper end of the first stepped hole 211, the lower end of the first threaded column 213 is threadedly connected to the inside of the threaded groove 212, the top of the abutting piece 214 is fixedly connected to the bottom of the first threaded column 213, the outer wall of the abutting piece 214 is slidably connected to the lower end of the first stepped hole 211, and the middle of the detection block 215 is movably penetrated through the middle of the first threaded column 213.

[0037] Second stepped holes 216 are arranged side by side in the middle of one side of the sliding block 103, a movable cavity 217 is opened in the inner part of one side of the sliding block 103 and is located at the lower end of the second stepped hole 216 and is interconnected, the outer wall of the stepped column 218 is slidably connected to the inside of the second stepped hole 216 and is movable inside the movable cavity 217, both ends of the second spring 219 are respectively fixedly connected to one end of the stepped column 218 and the bottom surface of the second stepped hole 216, both sides of the surface of the abutting block 220 are fixedly connected to the bottom of the stepped column 218, the outer wall of the abutting block 220 is slidably connected to the inside of the movable cavity 217, the bottom of the second threaded column 221 is fixedly connected to the middle of the surface of the abutting block 220, and the middle of the second threaded column 221 is threadedly connected to the inner part of one side of the sliding block 103.

[0038] When the accuracy of the adjustment surface 101 is worn and the gap of the selector cannot be adjusted, the operator first aligns the front end of the detection block 215 inside the sliding block 103 with the blade of the selector, and then manually rotates the second threaded column 221. Through the rotation of the second threaded column 221, the abutting block 220 begins to slide inside the movable cavity 217. Through the sliding of the movable cavity 217, the stepped column 218 begins to slide inside the second stepped hole 216, and the second spring 219 begins to contract. When the bottom of the abutting block 220 contacts and abuts against the surface of the detection block 215, the fixation of the detection block 215 can be completed.

[0039] After the fixation of the detection block 215 is completed, the operator manually pushes the sliding block 103, and the sliding block 103 begins to approach the adjustment surface 101. At this time, the detection block 215 will first contact the moving block 207. At this time, according to the requirements, the gap between the blade and the adjustment surface 101 is controlled within 0.3 mm. At this time, through the continuous sliding of the sliding block 103, the moving block 207 is squeezed, and the sliding column 203 begins to slide inside the circular through hole 202. Through the sliding of the sliding column 203, the square block 206 begins to slide inside the square hole 205. The operator can conveniently observe the distance of the gap between the blade and the adjustment surface 101 through the sliding distance of the square block 206. At this time, one of the two first springs 208 begins to contract and the other begins to extend. Through the characteristics of the two first springs 208, it can be ensured that there is no error in the sliding out of the square block 206.

[0040] When the gap between the blade and the adjustment surface 101 is controlled within 0.3 mm, the operator manually rotates the first threaded columns 213 on both sides of the sliding block 103. Through the rotation of the first threaded columns 213, the abutting piece 214 slides in the first stepped hole 211. When the abutting piece 214 abuts against the surface of the L-shaped adjustment seat 1, the sliding block 103 can be fixed. Through the fixation of the sliding block 103, the adjusted gap can be fixed.

[0041] The implementation principle of a needle selection mechanism for a circular knitting machine in an embodiment of the present application is as follows: When the accuracy of the adjustment surface 101 is worn and the clearance of the needle selector cannot be adjusted, the operator aligns the front end of the detection block 215 with the blade of the needle selector, and then rotates the second threaded column 221. The abutting block 220 starts to slide inside the moving cavity 217, and at the same time drives the stepped column 218 to slide inside the second stepped hole 216 until the abutting block 220 abuts against the detection block 215, and the fixation of the detection block 215 can be completed. Subsequently, the operator pushes the sliding block 103 to move the sliding block 103 towards the adjustment surface 101. At this time, the detection block 215 contacts the moving block 207, and the moving block 207 is squeezed to drive the sliding column 203 to move, and the square block 206 starts to slide inside the square hole 205. At this time, the distance between the blade and the adjustment surface 101 can be judged by the sliding distance of the square block 206 on one side of the second fixed block 204 until the specified distance is reached. When the specified distance is reached, the operator rotates the first threaded column 213 to make the abutting piece 214 slide in the first stepped hole 211 and abut against the surface of the L-shaped adjustment seat 1, and the sliding block 103 and the adjusted clearance can be fixed.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
