Description

Technical Field

[0001] The invention relates to the technical field of lace detection, in particular to a lace detection device. Background Art

[0002] Lace inspection includes appearance inspection, physical property inspection and chemical property inspection. Appearance inspection refers to the inspection of patterns, designs, colors and sizes on lace to ensure the integrity, clarity, symmetry, color uniformity, color fastness and size accuracy of lace. Physical property inspection refers to the tensile strength, tear strength and elastic recovery of lace. Chemical property inspection refers to the fiber composition inspection and harmful substance inspection of lace. The appearance inspection of lace is usually carried out by workers' naked eye inspection. The tensile, tear and elastic recovery in the physical property inspection can be tested by tensile testing machine and tear strength tester respectively. The fiber composition inspection in the chemical property inspection of lace is carried out by combustion method or chemical dissolution method. The harmful substance detection is carried out by formaldehyde detector, heavy metal detector and azo dye detector.

[0003] In the current existing technology, the tensile performance test of lace is carried out by using a tensile testing machine, which requires workers to cut the lace samples into standard samples of a certain length and width, place the two ends of the lace samples in the clamps respectively, and then manually adjust the clamps to clamp the lace samples, which makes the labor intensity of the workers higher. In addition, due to the material of the lace itself, the upward pulling force acts too quickly during the tensile test, causing the lace samples to break, thereby affecting the accuracy of the test data. Therefore, a lace detection device is proposed to solve the above problems. Summary of the invention

[0025] See also Figure 1-4 A lace detection device includes a tensile testing machine 1. A detection frame 2 and a data display platform 3 are arranged on the top of the tensile testing machine 1. A lifting structure, a clamp structure and a driving structure are arranged on the detection frame 2. The detection frame 2 is fixedly installed on the top of the tensile testing machine 1. The data display platform 3 is fixedly installed on the top of the tensile testing machine 1 and is located on the right side of the detection frame 2.

[0026] In this embodiment, the lifting structure includes a tension detection plate 41 fixedly installed on the inner bottom wall of the detection frame 2, a threaded sleeve 42 is rotatably installed on the top of the detection frame 2, and a support component 43 for supporting the rotation of the threaded sleeve 42 is installed on the top of the detection frame 2. The support component 43 includes a circular groove and a bearing. The circular groove is opened at the top of the detection frame 2, and the bearing is fixedly installed inside the circular groove. One end of the threaded sleeve 42 passes through the bearing and is fixedly connected to the inner circumferential wall of the bearing, so as to facilitate the use of the bearing to support the rotation of the threaded sleeve 42. The internal thread of the threaded sleeve 42 is connected to a threaded column 44 with one end passing through and extending to the inside of the detection frame 2. An anti-slip component 45 is fixedly installed on the top of the threaded column 44. A guide component 46 for limiting the moving trajectory of the threaded column 44 is provided inside the detection frame 2. A mounting plate 47 for connecting a fixture structure is fixedly installed on the top of the tension detection plate 41 and the bottom of the threaded column 44.

[0027] Among them, the guide component 46 includes a guide rod and two guide frames, the two guide frames are fixedly installed on the inner top wall of the detection frame 2, the guide rod is fixedly connected to the threaded column 44, and the two ends of the guide rod respectively penetrate and extend into the interior of the two guide frames, and the outer surfaces of the guide rod are respectively slidably connected to the inner walls of the two guide frames to limit the directional trajectory of the threaded column 44 moving up and down.

[0028] By adopting the above technical solution, it is possible to control the rotation of the threaded sleeve 42 by using the driving structure, so that the threaded column 44 connected to the internal thread of the threaded sleeve 42 moves upward, and the moving threaded column 44 drives the top clamp structure and one end of the lace sample to move upward synchronously, thereby applying a slow pulling force to the lace sample, and the pulling force detection board 41 displays the pulling force accuracy data in real time on the data display machine 3.

[0029] In this embodiment, the clamp structure includes two clamp frames 48 fixedly mounted on opposite sides of two mounting plates 47, and the two clamp frames 48 are respectively slidably mounted with two clamps 49 for fixing the lace samples, and the four clamps 49 include a connecting rod and a tooth plate, the connecting rod is fixedly connected to one end of the connecting rod, one end of the connecting rod passes through and extends to the outside of the clamp frame 48, and the clamp frame 48 is slidably connected to the outer surface of the connecting rod, and the two tooth plates inside the clamp frame 48 are meshed with each other, so as to firmly fix and clamp the lace samples, and the two clamp frames 48 are provided with a propulsion component 50 for controlling the movement of the clamp 49.

[0030] In addition, the two propulsion components 50 each include two electric push rods, which are fixedly mounted on the clamp frame 48. The telescopic ends of the two electric push rods are respectively fixedly connected to the two tooth plates, so that the movement of the clamp 49 can be automatically controlled by the telescopic movement of the electric push rods, thereby automatically clamping and fixing one end of the lace sample.

[0031] By adopting the above technical solution, one end of the lace sample is placed between the opposite sides of the two clamps 49, and then the two electric push rods in the propulsion component 50 are started, and the two clamps 49 are moved to the opposite side by extending the two electric push rods, so that the lace sample is firmly clamped and fixed by the tooth plates in the two clamps 49, and then the other end of the lace sample is fixed in the same way.

[0032] In this embodiment, the driving structure includes an asynchronous motor 51 fixedly mounted on the top of the detection frame 2. A transmission component 52 for driving the threaded sleeve 42 to rotate is provided on one side of the asynchronous motor 51. The transmission component 52 includes two bevel gears, and the outer surfaces of the two bevel gears are meshed with each other. The two bevel gears are respectively fixedly mounted on the output shaft of the asynchronous motor 51 and the outer surface of the threaded sleeve 42, so as to facilitate the rotation of the output shaft and utilize the two meshing bevel gears to drive the threaded sleeve 42 to rotate. A clamp for fixing the asynchronous motor 51 is fixedly mounted on the top of the detection frame 2.
