ELEH Button Pull Tester

Button pull tester

1 Introduction:

The button pull tester can be equipped with various push-pull force meters and special fixtures, which are specially used to measure the button closing force or the breaking force of clothes. Detecting the strength of buttons and buttons is an important criterion, especially in the design and manufacture of baby and children's clothing.

2. Purpose:

The test purpose of the button tester is to define the responsibility of the garment manufacturer to ensure that the buttons, buttons, and fasteners can be properly fixed on the garment to prevent the buttons, etc. from detaching from the garment, posing a risk for the baby to swallow. Therefore, all the buttons, buttons, and fixed decorative parts on the garment (which can be put into the small object measuring device as a whole) need to pass the test of the button tester.

3. Significance and role:

1. The test method of this instrument is used to measure the strength of the vertical tension test on buttons and clothing, and the buttons and buttons are not pulled to get out of the clothing.

2. The button sewing specifications required by this method should be in accordance with the standards set by the button manufacturer.

3. This test method is used to establish the relevance of different wearing environments and to compare the types and brands of different buttons.

4. This standard may include hazardous materials, operations, and instruments, and the standard does not list all safety issues that may arise during use. It is therefore the responsibility of the user of this standard to establish relevant safety and health rules, and to determine appropriate rules before use.

5. All buttons need to be sewn on the fabric with chain stitches.

6. According to the test requirements, when the maximum button size is greater than 6mm or less than / equal to 6mm, the buttons must be able to withstand 90N and 50N tensile forces.

4. Instrument introduction:

· The base of the machine is made of cast steel, which has good stability and is suitable for indoor table testing.

· Gear transmission, stable and accurate displacement, side strong arm handle loading, rapid after-load, convenient testing.

· The side hand wheel adjusts the height of the movable body. During the test process, different clamps can be quickly clamped and adjusted to a reasonable height.

· Standard button clamps on the base can move left and right and back and forth for convenient and accurate clamping.

· The button clamp is loaded by a strong arm, and the pin is pressed tightly with a soft pad to make the button clamp more stable and reliable.

· Length × Width × Height: 292mm × 222mm × 830mm.

· Stroke: 48mm.

· Rated load: 500N.

Five, the installation method of the instrument:

1. Installation method of push-pull force meter:

A. Use M4 wrench to loosen 4 M 4 × 15 hex socket head screws on the dynamometer mounting plate, and remove the dynamometer mounting plate;

B. When installing the digital display push-pull force gauge, use M4 hex wrench to insert 4 M4 × 10 hex screws in the accessory bag through 90 × 40 holes on the dynamometer mounting plate and screw them into 4 dynamometers Install the dynamometer on the dynamometer mounting plate in the threaded hole of M4; or use a Phillips screwdriver to pass the four M3 spring pad two combination screws in the accessory bag through the 145 * 30 mounting holes on the dynamometer mounting plate , Fix and adjust the dynamometer.

C. When the pointer push-pull gauge is installed, use a Phillips screwdriver to remove the four M3 × 10 screws on the back cover of the push-pull gauge, and pass the four M3 spring pad two combination screws in the accessory bag through the dynamometer to install 145 * 30 mounting holes on the board, screw into the 4 M3 threaded holes on the back cover of the dynamometer (remove the screw holes of M3 × 10 screws);

D. After the push-pull gauge is installed, reinstall the dynamometer mounting plate on the rack with an M4 allen wrench.

E. If you use dynamometers from other manufacturers, if they are not 90 * 40 and 145 * 30 mounting holes, please contact the manufacturer first and order the dynamometer mounting plate.

3. Installation method of upper fixture:

Install the female threaded connection hook in the attachment for the upper clamp on the test rod of the push-pull gauge. Hang the upper clamp on the hook.

6. General test operation process:

1. Place the cloth with the button fasteners on the base fixture (under the compression block with round holes), keep the button facing up, press the lever handle to clamp the cloth piece (and ensure that the fabric has been pressed ).

2. Rotate the upper clamp counterclockwise to open its grip.

5. Rotate the hand wheel of the fuselage to make the upper clamp move downwards and be able to grasp the buttons.

6. Raise the handle to move the fixture upwards and pull the button to achieve the test purpose.

Seven, daily maintenance and maintenance:

1. Do not overload the instrument. The rated load of this instrument is 300N.

2. Pay attention to daily maintenance work and keep all parts of the instrument clean.

3. When the operation of the instrument is sluggish and inflexible during use, please apply a small amount of lubricant to the screw in the rack and standpipe. When the machine fails, please contact the manufacturer or the sales point in time (do not disassemble or repair without authorization).
