[0036] The principle of this invention:
[0037] First test mode: At this time, the sofa armrest frame 22 is moved to both sides, which is slid by the installation slide plate 13 and the slide groove 12. Then, the fabric to be tested is laid horizontally on the surface of the sofa body 21, and the two sides are spread into the gap holes of the sofa armrest frame 22. Then, the sofa armrest frame 22 is slid towards the sofa body 21. After the limit is completed, different pressing heads are taken out and installed at the bottom of multiple top material rods 48 through the installation thread 485.
[0038] Next, the motor 414 on one side is turned on, causing the drive gear 415 to rotate. The drive gear 415 drives the passive gear 416 connected to the bottom roller 417 to rotate, thereby causing the roller 417 to start rolling. The rolling of the roller 417 causes multiple first eccentric wheels 419 on the surface to start rotating. The first eccentric wheels 419 squeeze the corresponding pusher seat 482, causing the pusher seat 482 to drive the top rod 48 connected to the bottom to press down on the sofa fabric multiple times. At the same time, the pusher seat 482 achieves a reset effect after being pressed down through the limit rods 483 and springs 484 on both sides of the limit plate 481. During the pressing process, the roller 417 and the first crossbar 47, which are synchronously connected through the side mounting bracket 418, are activated. The first crossbar 47 slides left and right through the electric slides 45 on both sides. The roller 417 slides left and right on the longitudinal rod 412 through the third sliding sleeves 413 on both sides. By repeatedly pressing on multiple positions, the actual effect after a person sits on the sofa multiple times is compared.
[0039] The controller controls the number of presses and the frequency of motor 414 rotation. After the press test is completed, the small cylinder 57 is activated, which pushes the second horizontal bar 52 at the output end to move forward along the longitudinal rods 412 on both sides. At this time, the sensing plate 62 on one side contacts the diffuse reflection sensor 61 on the third sliding sleeve 413 on the other side. The electric valve is then opened, and the electrically controlled valve 55 drips the detection liquid in the detection liquid tank through the first water outlet pipe 54 and multiple water outlet holes on both sides onto the detection fabric on the surface of the sofa body 21 to detect the fabric. If the fabric leaks water, it will drip along the gap created by the press into the detection chamber 23 at the bottom. The detection paper is installed between the two clamping frames 31 in the detection chamber 23 to detect the dripping. At the same time, the detection structure 3 can be pulled out as a whole by the handle 35 to replace the detection paper.
[0040] Second test mode: The electric slide table 45 drives the roller shaft 417 connected to the side mounting bracket 418 to slide back and forth. The two second eccentric wheels 73 sleeved on the surface of the roller shaft 417 are longer than the first eccentric wheel 419, so that the second eccentric wheels 73 can squeeze the pressure roller 710 backward when moving backward. This allows the pressure roller 710 to move backward through the mounting slide 76 within the limit frame 711. At the same time, the pressure roller 710 is rotatably set in the mounting slide 76 through the connecting block 79 on one side, so that the pressure roller 710 is pressed down at the force end, thereby squeezing the second test liquid tank 71. This squeezes the hard film at the multiple outlets of the second water outlet pipe 72, resulting in water discharge. This can achieve real-time testing every time the top rod 48 punches the fabric. When testing is not required, the connection between the pressure roller 710 and the connecting block 79 can be pulled out, so that the second eccentric wheels 73 are not squeezed, thus allowing testing in the first test mode.
[0041] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
