[0026] Reference Figures 1-4 According to an embodiment of the present invention, a multi-station air permeability testing machine includes a machine base 11, a turntable 12 rotatably connected to the machine base 11, a plurality of clamping components distributed circumferentially on the turntable 12, and a rotary motor 13 for driving the turntable 12 to rotate inside the machine base 11.

[0027] In addition, it includes a lifting base 21, in which an upper slide plate 22 and a lower slide plate 23 are slidably connected. An upper fixed cylinder 24 and a lower fixed cylinder 25 are respectively installed on the sides of the upper slide plate 22 and the lower slide plate 23 that are close to each other. It also includes a control mechanism for controlling the upper fixed cylinder 24 and the lower fixed cylinder 25 to move towards each other to engage with the clamping assembly. The upper side of the machine base 11 is provided with a mounting groove, and the lifting base 21 is fixed in the mounting groove so that the upper fixed cylinder 24 and the lower fixed cylinder 25 are located on the upper and lower sides of the turntable 12.

[0028] It also includes a pump (not shown in the figure) for supplying air to the upper fixed cylinder 24, and the lower fixed cylinder 25 is provided with an air outlet and a gas flow sensor.

[0029] Workers can load different types of fabric to be tested into each of the clamping components. The turntable 12 will rotate so that the upper fixing cylinder 24 and the lower fixing cylinder 25 are sequentially connected to the rightmost clamping component, and the air permeability of the fabric inside is tested.

[0030] like Figure 3 As shown, the clamping assembly includes a boss 31 on the turntable 12 and a pressure ring 32 that can cover the upper side of the boss 31. It also includes a locking mechanism for locking the pressure ring 32 onto the boss 31. The upper side of the boss 31 is provided with a vent hole 33 that penetrates the turntable 12 downward. The diameter of the vent hole 33 is adapted to the inner diameter of the pressure ring 32. The fabric can be clamped between the pressure ring 32 and the boss 31.

[0031] To increase airtightness, an inner convex ring 34 is integrally formed on the lower side of the pressure ring 32. The function of the inner convex ring 34 is to press the fabric. A first sealing ring is installed inside the lower side of the pressure ring 32 outside the inner convex ring 34. An outer convex ring that can press against the first sealing ring is provided on the upper side of the boss 31.

[0032] The lower side of the upper fixed cylinder 24 is equipped with a second sealing ring that can press against the upper side of the pressure ring 32, and the upper side of the lower fixed cylinder 25 is equipped with a third sealing ring that can press against the lower side of the turntable 12 and is fitted outside the vent hole 33.

[0033] In this embodiment, the locking mechanism includes an arc panel 35 disposed on the lower side of the pressure ring 32. The arc panel 35 is provided with two symmetrically distributed members, and a rotating ring 36 is rotatably connected to the outside of the boss 31. A threaded ring 37 is fixedly provided on the upper side of the rotating ring 36, and the arc panel 35 can be threadedly connected to the threaded ring 37.

[0034] In the fabric clamping process, the worker first places the fabric on the boss 31, then covers the boss 31 with the pressure ring 32. The worker then holds the pressure ring 32 with one hand to prevent it from rotating, and rotates the rotating ring 36 or the threaded ring 37 with the other hand. At this time, the arc panel 35 is threaded into the threaded ring 37 until the pressure ring 32 presses the fabric tightly onto the boss 31. At this time, the fabric clamping work of one clamping assembly is completed.

[0035] The control mechanism includes a lifting motor 41 mounted on the lifting seat 21. A bidirectional threaded shaft 42 driven and controlled by the lifting motor 41 is rotatably connected inside the lifting seat 21. The upper slide plate 22 and the lower slide plate 23 are respectively threaded to two sections of threads inside the bidirectional threaded shaft 42. That is, when the lifting motor 41 drives the bidirectional threaded shaft 42 to rotate, the upper slide plate 22 and the lower slide plate 23 will move towards each other until the upper fixed cylinder 24 and the lower fixed cylinder 25 abut against the upper side of the rightmost pressure ring 32 and the lower side of the turntable 12 (at this time, the lower fixed cylinder 25 is sleeved outside the vent hole 33).

[0036] To prevent the upper slide plate 22 from descending when the arc panel 35 is in a high position and not tightened, which could damage the lifting seat 21 or the threaded shaft 42, a rangefinder is installed on the side of the upper slide plate 22, and an alarm light (not shown in the figure) is installed on the lifting seat 21. When the upper slide plate 22 is in the highest position and the turntable 12 has rotated to its position, if the rangefinder senses that the distance between it and the rightmost pressure ring 32 does not meet the standard, the alarm light will sound an alarm, and the lifting motor 41 will not be powered on at this time to protect the equipment.

[0037] In the second embodiment of the multi-station air permeability testing machine, in order to further improve the testing accuracy, pressure sensors 26 are respectively provided in the upper fixed cylinder 24 and the lower fixed cylinder 25. When the pump is working, the operator can judge the relative value of the air permeability of the batch of fabric by the pressure difference between the two pressure sensors 26 and the reading of the flow sensor. This is the prior art and will not be described in detail here.

[0038] Testing process:

[0039] First, the staff clamps the different types of fabric between the protrusions 31 and the pressure rings 32. After clamping, without alarming, the lifting motor 41 is powered on and drives the upper slide plate 22 and the lower slide plate 23 to move closer to each other until the upper fixing cylinder 24 and the lower fixing cylinder 25 are connected to the rightmost clamping assembly. Then, the air pump works and blows air downward into the pressure rings 32. The air then penetrates the fabric and enters the lower fixing cylinder 25 through the vent 33. At this time, the data in the gas flow sensor and the pressure sensor 26 can be recorded.

[0040] After the fabric test in one of the clamping components is completed, the upper slide plate 22 and the lower slide plate 23 move away from each other and reset. Then, the rotary motor 13 drives the turntable 12 to rotate a certain angle so that the other clamping component moves to the far right and is tested again.

[0041] After the turntable 12 rotates once, the fabrics in each of the clamping components have been tested, and the staff can remove the fabrics and compare the data to compare the airtightness of each fabric.

[0042] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
