[0023] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-6 As shown, this embodiment discloses a circular knitting needle cylinder testing device, which is used to measure the qualification of the needle groove 102 and the deformation of the outer wall of the circular knitting needle cylinder 101 after grooving.

[0025] This embodiment includes a platform 1, a rotating platform 2, a first detection device 3, and a second detection device 4. The rotating platform 2, the first detection device 3, and the second detection device 4 are mounted on the platform 1. The rotating platform 2 includes a three-jaw chuck 21 and a motor 22. The motor 22 is connected to the three-jaw chuck 21 through a reducer to drive it to rotate. The upper end face of the three-jaw chuck 21 is fixed with a circular knitting needle cylinder 101. The circular knitting needle cylinder 101 and the three-jaw chuck 21 are concentrically arranged. The three jaws of the three-jaw chuck 21 expand radially outward and abut against the inner wall of the circular knitting needle cylinder 101 to fix the circular knitting needle cylinder 101. The circular knitting needle cylinder 101 includes a plurality of needle grooves 102, and a partition 103 is formed between two adjacent needle grooves 102.

[0026] The first detection device 3 is located in the rotation direction of the three-jaw chuck 21. The first detection device 3 includes a first lifting device 31, a first connecting rod 32, a first support member 33, and a displacement sensor 34. The first lifting device 31 is an electric lifting device. The upper end of the lifting rod of the first lifting device 31 passes through the platform 1. The first connecting rod 32 is installed on the upper end of the first lifting device 31. The first lifting device 31 can drive the first connecting rod 32 to move up and down. The first connecting rod 32 can be adjusted according to the height of the circular knitting machine syringe 101. It can also adjust the position of the outer wall of the circular knitting machine syringe 101. The upper end of the part of the circular knitting machine syringe 101 with the needle groove 102 is the most prone to deformation. The position of the outer wall of the circular knitting machine syringe 101 is generally measured at a relatively high position. The upper end of the first lifting device 31 has an opening that can be locked with bolts. The first connecting rod 32 is adjusted radially along the first lifting device 31 along the circular knitting machine syringe 101. The pressure of the first rotating wheel 331 against the circular knitting machine syringe 101 can be adjusted according to the diameter of the circular knitting machine syringe 101.

[0027] A first connecting rod 32 extends radially along the circular knitting machine syringe 101. A telescopic first support member 33 is mounted on the first connecting rod 32. The first support member 33 includes a guide rod 332, part of which is located within the first connecting rod 32. A first spring 333 is mounted on the guide rod 332. A first rotating wheel 331 is mounted on one end of the first support member 33 facing the circular knitting machine syringe 101. The first rotating wheel 331 abuts against the outer wall of the circular knitting machine syringe 101. The first spring 333 supports the first rotating wheel 331 abutting against the circular knitting machine syringe 101. The first rotating wheel 331 can rotate with the rotation of the circular knitting machine syringe 101. A displacement sensor 34 is mounted on the first connecting rod 32. The displacement sensor 34 includes a telescopic connecting rod 341, one end of which is fixedly connected to the first support member 33. The displacement sensor 34 measures the circumferential changes and fluctuations of the outer wall of the circular knitting machine syringe 101. Figure 5 As shown, when the first rotating wheel 331 is located at the needle groove 102, the first rotating wheel 331 will be closer to the center of the circular knitting machine syringe 101 than when the first rotating wheel 331 is located at the partition 103. That is, the connecting rod 341 of the displacement sensor 34 extends. When the first rotating wheel 331 is located at the partition 103, the connecting rod 341 of the displacement sensor 34 extends and retracts. As the circular knitting machine syringe 101 rotates, the connecting rod 341 will continuously extend and retract. The displacement sensor 34 can record the displacement change curve. If the needle groove 102 is deformed and the width changes, the displacement change curve recorded by the displacement sensor 34 will show an abnormality and an alarm will be triggered. It can comprehensively measure the quality of the needle groove 102 of the circular knitting machine syringe 101.

[0028] The second detection device 4 is located in the rotation direction of the three-jaw chuck 21. The second detection device 4 includes a second lifting device 41, a second connecting rod 42, a second support member 43, and an angle sensor 44. The second connecting rod 42 is installed on the upper end of the second lifting device 41. The second lifting device 41 can drive the second connecting rod 42 to move up and down. The second connecting rod 42 can be adjusted radially along the circular knitting machine cylinder 101 in the second lifting device 41. The second lifting device 41 has the same structure as the first lifting device 31. The second lifting device 41 can adjust the height of the second connecting rod 42. The upper end of the second lifting device 41 is provided with an opening that can be locked with bolts. The distance between the second support member 43 and the circular knitting machine cylinder 101 can be adjusted according to the diameter of the circular knitting machine cylinder 101.

[0029] The second connecting rod 42 extends radially along the cylindrical syringe 101 and is rotatably connected to the second support member 43. The second support member 43 includes a mounting plate 432, which extends axially along the cylindrical syringe 101. The mounting plate 432 mounts a roller assembly and a fourth roller 435, which are spaced apart along the length of the mounting plate 432. The second connecting rod 42 is provided with a connecting plate 421, which mounts two second springs 422. The second support member 43 includes a third connecting rod 431, which is hinged to the second connecting rod 42. The two second springs 422 are located on the upper and lower sides of the third connecting rod 431 and are connected to the mounting plate 432. The mounting plate 432 is supported by two second springs 422 and remains vertical in the initial state. The rotating wheel assembly and the fourth rotating wheel 435 abut against the circular knitting machine syringe 101. The angle sensor 44 is mounted on the second connecting rod 42. The angle sensor 44 includes a rotating rod 441, one end of which is fixed to the second support member 43. When the circular knitting machine syringe 101 rotates, if the outer wall of the circular knitting machine syringe 101 protrudes or dents, the mounting plate 432 will deviate at an angle, and the rotating rod 441 of the angle sensor 44 will rotate. The angle of rotation is recorded numerically, which can detect the unqualified parts of the outer wall of the circular knitting machine syringe 101. The angle sensor 44 measures the axial changes of the outer wall of the circular knitting machine syringe 101.

[0030] like Figure 4 , Figure 6 The outer wall portion of the circular knitting machine syringe 101 with needle groove 102 is a slotted area 1011, and the outer wall portion without needle groove 102 is a smooth area 1012. The second rotating wheel 433 and the third rotating wheel 434 are located in the slotted area 1011, and the fourth rotating wheel 435 is located in the smooth area 1012. Since the outer wall of the slotted area 1011 will have unevenness due to the presence of needle groove 102, the rotating wheel group is set with the second rotating wheel 433 and the third rotating wheel 434. The second rotating wheel 433 and the third rotating wheel 434 are distributed vertically. When the second rotating wheel 433 is located in needle groove 102, the third rotating wheel 434 is located in partition 103. Similarly, when the second rotating wheel 433 is located in partition 103, the third rotating wheel 434 is located in needle groove 102, so that the rotating wheel group can initially abut against the outer wall of partition 103, eliminating the interference of needle groove 102 on measurement.
