Description

A device for detecting the winding and unwinding of acupuncture needle springs Technical Field

[0001] This utility model belongs to the field of acupuncture needle testing devices, specifically relating to a device for testing the winding and unwinding of acupuncture needle springs. Background Technology

[0002] Acupuncture, as an ancient and effective traditional Chinese medicine therapy, relies heavily on the quality of acupuncture needles for its therapeutic effect. Acupuncture needles are usually made of metal, and the design of the spring part is crucial to the flexibility of the needle and the insertion effect. Therefore, the quality of the spring winding becomes a key control point in the production process of acupuncture needles.

[0003] Traditional acupuncture needle spring winding processes mostly rely on manual or semi-automatic equipment. However, during the winding process, it is usually difficult to quickly and accurately detect the winding quality of the spring. Current wire feeding detection devices are generally unable to accurately detect the tension and stability of acupuncture needle springs, which needs further improvement.

[0004] Therefore, an acupuncture needle spring winding and unwinding detection device is proposed, which can accurately detect the tension and stability of the acupuncture needle spring. Summary of the Invention

[0005] To overcome the problem that existing wire-laying testing devices are usually unable to accurately detect the tension and stability of acupuncture needle springs, an acupuncture needle spring winding wire-laying testing device is proposed.

Directly below the two guide components, a limiting component is provided on the upper left side of the testing platform. The inner wall of the limiting component is provided with the acupuncture needle body. One end of the acupuncture needle body is a pointed tip. Two third grooves are opened on the side wall of the acupuncture needle body near the other end. A fixing mechanism for fixing the acupuncture needle body is provided on the upper right side of the testing platform. The first test rope is pulled together on the third winding component, the first guide component, the third guide component, and the first winding component. The second test rope is pulled together on the fourth winding component, the second guide component, the fourth guide component, and the second winding component. The first test rope and the second test rope are respectively located between the gaps of the springs on the side wall of the acupuncture needle body.

[0038] Please refer to Figures 1 and 6. In this embodiment, the first guide assembly 7 includes a third U-shaped frame 701, a first rotating roller 702, and a second take-up reel 703. The upper end of the test platform 1 is fixedly connected to a second bracket, and the side end of the second bracket is fixedly connected to the third U-shaped frame 701. The first rotating roller 702 is rotatably mounted on the inner walls of both sides of the third U-shaped frame 701. The middle of the side wall of the first rotating roller 702 is fixedly connected to a second take-up reel 703 for limiting the first test rope 22, which is conducive to the stable placement of the first test rope 22.

[0039] Working principle: First, the first electric cylinder 801 is activated to move the moving block 802, and the inner wall of the first through hole 803 is used to limit the side wall of the acupuncture needle body 19.

[0040] Next, the mounting plate 904 is placed on both sides of the inner wall of the U-shaped plate 902. Then, the second electric cylinder 901 is turned on to move the extrusion block 903 to the left, pressing and fixing the mounting plate 904 to the inner wall of the U-shaped plate 902. Then, the side wall of the other end of the acupuncture needle body 19 is placed on the inner wall of the second through hole 905. The two micro cylinders 906 are turned on so that the output shaft of the micro cylinder 906 passes through the third through hole 907 and enters the inner wall of the third groove 20, thereby pressing and fixing the acupuncture needle body 19.

[0041] Then, the first test rope 22 and the second test rope 23 are placed in the gaps of the springs on the side wall of the acupuncture needle body 19, respectively. Then, the third winding assembly 6 and the first winding assembly 4 are simultaneously activated to wind up the first test rope 22, and the second winding assembly 5 and the fourth winding assembly 11 are simultaneously activated to wind up the second test rope 23. The first test rope 22 and the second test rope 23 will pull the springs on the side wall of the acupuncture needle body 19, respectively. After the first test rope 22 and the second test rope 23 are pulled in opposite directions for a certain distance, the pulling on the first test rope 22 and the second test rope 23 is released. At this time, the spring will rebound. If the spring can rebound completely after being pulled a certain distance, it proves that the quality is good. If it cannot rebound completely, it indicates that the tension and stability of the spring are insufficient.

[0042] Alternatively, the test block 18 can be attached to the spring of the acupuncture needle body 19, and the third electric cylinder 21 can be activated so that the output shaft of the third electric cylinder 21 abuts against the support block 17, thereby positioning the test block 18. In this way, during the tensile test, the spring pulled by the first test rope 22 will only undergo a small range of compression, which can achieve another form of tension testing. The spring returning to its original position indicates that the spring's rebound ability is intact.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
