Description

Technical Field

[0001] This utility model relates to the technical field of circular needle surface inspection tools, and in particular to a device for detecting surface defects of circular needles. Background Technology

[0002] Circular knitting needles are special-shaped needles used on circular knitting machines for reciprocating motion. They are usually made of metal or plastic. The shape of the circular knitting needle is designed very precisely to ensure that it can pass smoothly through the needle barrel and needle plate during the knitting process and accurately perform operations such as yarn suction and weaving. There are many types of circular knitting needles, including plain knitting needles, reciprocating needles, and tongue needles for circular knitting machines. Each type of needle has its unique function and use. In textile production, circular knitting needles are one of the most critical tools. They are widely used and can play a role in the production of knitted products such as socks, sweaters, and knitted hats. During the production process, defects such as cracks, burrs, and rust may appear on the surface of the circular knitting needles. Therefore, it is necessary to inspect the surface of the circular knitting needles for defects.

[0003] Existing testing devices mostly involve placing a circular needle on a conveyor belt and then moving it to the testing area. The testing area often uses a single light source or a fixed viewing angle, and can only test one side of the circular needle at a time, which cannot fully cover the complex curved surface of the circular needle. Therefore, the above problems need to be solved. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example: See Figure 1-8 This utility model discloses a surface defect detection device for round needles, comprising a lower detection box 1, a turntable 2 mounted on the upper end of the lower detection box 1, and an upper detection box 3 mounted on the top surface of the turntable 2. The lower and upper detection boxes 1 and 3 facilitate the installation of detection heads 17. A transparent glass observation door 4 is hinged to the upper detection box 3, allowing for easy observation of the device's internal operation. A flipping mechanism is mounted on the turntable 2, and a positioning mechanism is mounted on the flipping mechanism. Multiple detection heads 17 are mounted on the inner sides of both the lower and upper detection boxes 1 and 3, facilitating the detection of round needles. The flipping mechanism includes a servo motor 6 mounted on one side of the bottom surface of the turntable 2 and a rotating plate 5 rotatably mounted inside the turntable 2. The servo motor 6, in conjunction with a lead screw 7, drives a moving block 8 on the rotating plate 5. Sliding; Rotary shafts are installed at both the connection points of the rotating plate 5 and the turntable 2. A lead screw 7 is installed at the output end of the servo motor 6 through a coupling. The lead screw 7 facilitates the movement of the moving block 8 to change the gravity distribution area of ​​the rotating plate 5. The moving block 8 is threadedly connected to the lead screw 7, which facilitates the installation of the limit block 9. A turntable 13 is rotatably installed in the middle of the rotating plate 5, which facilitates the movement of the counterweight block 16. The moving block 8 has an installation groove inside, and a spring 11 is installed in the installation groove. The spring 11 facilitates the movement of the limit block 9 to change the tilt angle of the rotating plate 5. The other end of the spring 11 is equipped with a limit block 9, which facilitates the fixation of the protrusion 10. The protrusion 10 is fixed on the limit block 9, which facilitates the movement of the moving block 8 within the first sliding groove 12. The protrusion 10 is inserted into the installation groove.

[0025] In this utility model, a first sliding groove 12 is provided at the lower end of the rotating plate 5, and one end of the limiting block 9 is slidably inserted into the first sliding groove 12. A second sliding groove is provided on one inner side of the first sliding groove 12, and the protrusion 10 is slidably installed in the second sliding groove. A counterweight 16 is installed on the periphery of the turntable 13, which facilitates the rotation of the turntable 13 by gravity. The rotating shaft is located at the center of both sides of the rotating plate 5. A positioning groove 14 is provided in the turntable 13, which facilitates the installation of the positioning clamp 15. The positioning groove 14 is inverted conical, and the positioning clamp 15 is inserted into the positioning groove 14, which facilitates the positioning of the circular needle. The positioning clamp 15 consists of a circular base and four annular plates equidistantly installed on the periphery of the base. The annular plates are made of rubber.

[0026] Working principle: When using this utility model, firstly, the positioning clamp 15 is pulled out from the positioning groove 14, and the detection piece is inserted into the positioning clamp 15. Then, the positioning clamp 15 is inserted back into the positioning groove 14. Since the positioning groove 14 is inverted conical and the positioning clamp 15 is malleable, the bottom of the positioning clamp 15 gradually narrows during insertion, and the upper end clamps the detection piece. The power is turned on, and the detection head 17 and servo motor 6 are turned on. The servo motor 6 drives the lead screw 7 to rotate forward and reverse, thereby driving the moving block 8 to slide in the first slide groove 12. When the protrusion 10 is located at the center of the second slide, the rotating plate 5 remains in a balanced state. When the moving block 8 drives the limiting block 9 to move, the weight in the moving direction increases, and the rotating plate 5 tilts in the moving direction. When the rotating plate 5 tilts, the counterweight block 16 located at the highest point of the turntable 13 drives the turntable 13 to rotate, and the highest point becomes the lowest point. Similarly, when the moving block 8 moves to the other direction, the turntable 13 rotates again, thereby realizing the all-round detection of the test piece. After the detection is completed, disconnect the power supply, pull out the positioning clamp 15, and take out the test piece.
