Description

Technical Field

[0001] The invention relates to the technical field of button tension testing equipment, in particular to a digital button tension testing instrument. Background Art

[0002] In ancient Rome, buttons were originally used as decorations, while brooches were used to fasten clothes. In the 13th century, buttons played the same role as they do today. At that time, people knew how to make buttonholes on clothes, which greatly improved the practical value of buttons. In the 16th century, buttons became popular. With the rise of fast fashion, buttons have changed from functional to creative, and have begun to be used as clothing decorations. After buttons are sewn on clothes, the firmness of the buttons needs to be tested, which requires the use of a button tensile tester.

[0003] The existing button tension testing equipment requires the operator to manually fix the clothing at the bottom of the button and then pull the button upward to test the tension. However, the button needs to be manually fixed by the operator before it can be lifted, which increases the workload of the operator.

[0004] At the same time, when fixing the buttons, due to the different sizes of buttons, the detection head needs to be replaced frequently. When replacing it, the tester needs to be turned off and can continue to work after the replacement is completed. This is inconvenient for operators to test the tensile force of buttons of different sizes.

[0005] At the same time, after the detection head is used for a long time, the buttons may break during the test, which will cause damage to the detection head and make it impossible for the detection head to hold the buttons, which makes it impossible to test the tensile force of the buttons, thus reducing the working efficiency of the button tensile tester. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that buttons need to be manually fixed by operators before they can be lifted, which increases the workload of operators, and because the sizes of buttons are different, the detection head needs to be frequently replaced. When replacing them, the tester needs to be turned off and can only continue to work after the replacement is completed, which is inconvenient for operators to use. In addition, buttons may break during testing, which will cause damage to the detection head, resulting in the detection head being unable to hold the button, which makes it impossible to test the tension of the button, which reduces the working efficiency of the button tension tester.

The damaged detection head can be replaced in the above manner, so that the button tension tester can continue to work, which improves the working efficiency of the button tension tester.

[0043] Working principle:

[0044] When a button's tensile force needs to be digitally tested:

[0045] Button fixing stage:

[0046] First, connect the external power supply of the third motor 12 and start the third motor 12. The third motor 12 drives the second lead screw 14 to rotate through the first belt 13. The second lead screw 14 drives the first lead screw 3 to rotate through the second belt 15. This makes the first lead screw 3 and the second lead screw 14 rotate synchronously. The first lead screw 3 and the second lead screw 14 drive the horizontal plate 4 to move. The horizontal plate 4 drives the square plate 5 to move. The square plate 5 drives the detection head 908 to move in the above manner. After the detection head 908 moves to a suitable height above the workbench 2, the third motor 12 stops working. Then, connect the external power supply of the first motor 601 and start the first motor 601. The first motor 601 drives the cam 602 to rotate. The cam 602 pushes the first vertical plate 604 to move through the roller 603 on the surface. The first vertical plate 604 drives the circular plate 908 to move. The rod 605 moves, and at the same time drives the first spring 606 to be compressed. At the same time, the first vertical plate 604 drives the cylinder 608 to move. The cylinder 608 drives the detection head rotation adjustment mechanism 7 below to move backward. The detection head rotation adjustment mechanism 7 drives the disk 8 to move backward. The disk 8 drives the detection head 908 fixed below to move. After the detection head 908 moves to a suitable position and moves the detection head 908 away from the upper surface of the workbench 2, the first motor 601 stops working. Then the operator places the clothes at the lower end of the button on the workbench 2 and fixes it through an external fixing device. Then the first motor 601 continues to work. In the above manner, the detection head 908 is moved to the workbench 2, and the button is fixed by the groove on the surface of the detection head 908. Then the first motor 601 stops working.

[0047] Button tension testing stage;

[0048] The third motor 12 drives the detection head 908 to rise in the above manner, and the detection head 908 drives the button to rise, and the pulling force of the button is recorded through the digital display screen 11, so as to know the pulling force when the button is separated from the clothing, and then the third motor 12 drives the button to reset in the above manner, and then the third motor 12 stops working, and then the first motor 601 moves the detection head 908 backward in the above manner, and then the first motor 601 stops working.

[0049] When buttons of different sizes need to be fixed:

[0050] The external power supply of the third motor 703 is turned on, the third motor 703 is started, the third motor 703 drives the circular plate 704 to rotate, the circular plate 704 drives the column 705 to rotate, the column 705 is inserted into the groove in the groove wheel 706 when rotating, so that the column 705 drives the groove wheel 706 to rotate intermittently, the groove wheel 706 drives the disc 8 to rotate in the above manner, thereby driving the detection head 908 to rotate, so that the detection head 908 of different sizes moves to the top of the workbench 2, and then the third motor 703 stops working. Then, buttons of different sizes can be fixed and tested in the above manner.

[0051] When the sensor head is damaged due to long-term use:

[0052] The operator pushes the handle 909, which drives the slider 905 to move. The slider 905 compresses the second spring 904 and also drives the extension rod 903 to move. The slider 905 pulls the conical block 906 out of the vertical rod 907. Then the operator removes the detection head 908 with the other hand and inserts the new detection head 908 into the disc 8. The operator releases the handle 909, and the second spring 904 rebounds to insert the conical block 906 into the vertical rod 907 to fix the new detection head 908. The replacement of the detection head 908 is completed.

[0053] Although the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
