Description

TECHNICAL FIELD

[0001] The utility model relates to a steel ring detection technical field especially a kind of steel ring air permeability detection device. BACKGROUND

[0002] In the production of glass fiber yarn, when the twisting process is carried out, the yarn is spun through the limiting and conditioning of the ring. Due to the continuous contact and friction of the yarn with the ring through the traction of the nylon hook, some quality-enhancing solvents carried on the yarn will seep into the tiny gaps inside the ring, causing problems with the oil permeability of the ring, resulting in insufficient lubrication when the nylon hook and the ring rotate, and ultimately leading to yarn fuzzing and quality defects such as hairiness.

[0003] The previous solution is to replace new spare parts or, but this method is costly. The second solution is to use an ultrasonic cleaning machine for heating and cleaning. However, since the effect of the steel ring after cleaning cannot be determined, only trial production can be carried out, and the product quality after production is qualitatively determined, which leads to unpredictable risks and long cycles, and the verification measures are lagging behind.

[0004] In the prior art, for example, Chinese patent CN201464333U granted on May 12, 2010, and Chinese patent CN212872118U granted on April 2, 2021, the steel ring is first immersed in oil to allow the oil to seep into the pores, then the steel ring filled with oil is taken out to allow the oil to escape from the pores of the steel ring to form bubbles, and the air permeability of the steel ring is observed.

[0005] However, in this method, the bubbles escaping from the steel ring only form near the steel ring, the bubbles exist for a short time and the phenomenon caused is not obvious, making observation inconvenient. For example, CN212872118U requires a turntable to rotate the steel ring to make it easier to observe the bubble situation comprehensively.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Example 1

[0032] like Figs. 1-2 As shown, this utility model provides a steel collar air permeability testing device, including: a box 1 containing oil 5; a fixing device 2 fixing the steel collar below the surface of the oil 5 in the box 1; a sealing device 3 sealing both ends of the inner ring of the steel collar; and a compressed air device 4 passing through the sealing device 3 and communicating with the inner ring of the steel collar to introduce compressed air into the steel collar.

[0033] Specifically, the box 1 includes at least a bottom wall and four side walls, which can hold oil 5; the box 1 can be made of tempered glass, making the side walls transparent so that it is easier to observe the bubbles escaping from the steel collar; of course, the box 1 can also be made of welded steel plates, because the fixing device 2 is a frame structure composed of a bottom plate 205, a column 206 and a top plate 201, which is open on all sides and not closed, so the bubbles escaping to the surface of the oil 5 can still be observed from the top of the box 1.

[0034] Steel collars are ring-shaped objects formed by smelting metal. The tiny gaps in their internal structure are oil channels. This is existing technology and can be purchased directly. Therefore, we will not go into the details of their structural principles.

[0035] In the working process, the fixing device 2 fixes the ring in the box 1, so that the ring is stable when the compressed gas device 4 supplies compressed gas into the ring. The oil 5 is higher than the ring. The compressed gas device 4 passes through the sealing device 3 to supply compressed gas into the inner ring of the ring. Since the two ends of the inner ring of the ring are sealed by the sealing device 3, the compressed gas can only enter the pores (i.e. oil channels) in the inner wall of the ring and escape from other positions of the ring through the pores. After escaping, these gases enter the oil 5 outside the ring to form bubbles and float and disperse, so that the number of bubbles on the surface of the oil 5 in the box 1 can be observed to determine the pore condition in the ring and further determine the air permeability state of the ring, thereby realizing the detection of the air permeability of the ring.

[0036] Compared with the prior art, the device can form bubbles in the oil 5 as long as the compressed gas device 4 supplies compressed gas. The bubbles exist for a longer time, and the phenomenon caused by the dispersion of the bubbles in the oil 5 is obvious and easy to observe.

[0037] Embodiment 2

[0038] The fixing device 2 includes a bottom plate 205, which is arranged in the box 1, and the ring is placed on the bottom plate 205. The fixing device 2 further includes a telescopic device and a gland 204, and the gland 204 is located above the bottom plate 205 and is connected with the telescopic device. The fixing device 2 further includes a top plate 201, which is connected above the bottom plate 205 through a stand column 206, and the telescopic device is connected to the top plate 201. The telescopic device includes a pneumatic cylinder 202 and a telescopic rod 203.

[0039] Specifically, in this embodiment, the bottom plate 205, the top plate 201 and the stand column 206 form a four-side open retainer. The telescopic rod 203 is controlled to extend by the pneumatic cylinder 202, so that the gland 204 presses down to clamp and fix the ring between the gland 204 and the bottom plate 205, and the sealing between the upper and lower end faces of the ring and the sealing pads 301 is improved by increasing the pressure. After the telescopic rod 203 is controlled to retract by the pneumatic cylinder 202, the detected ring can be taken out and replaced with a new ring to be detected.

[0040] Embodiment 3

[0041] The sealing device 3 includes sealing pads 301. The profile surface of the sealing pad 301 is larger than the inner ring of the ring. The top of the bottom plate 205 and the bottom of the gland 204 are respectively connected with the sealing pads 301. The top of the bottom plate 205 and the bottom of the gland 204 are respectively provided with grooves 207, and a part of the sealing pads 301 along the thickness direction is embedded in the grooves 207, and the other part is located outside the grooves 207.

[0042] Specifically, the sealing gasket 301 plays a protective and sealing role. The profile of the sealing gasket 301 is larger than the inner ring of the steel ring to completely cover and seal the inner ring of the steel ring. By providing a groove 207 on the end surface adjacent to the bottom plate 205 and the gland 204, and embedding a part of the sealing gasket 301 in the groove 207, the connection (such as gluing) between the sealing gasket 301 and the bottom plate 205 and the gland 204 is the bottom / top surface and a part of the four surrounding side surfaces. Compared with the prior art, the connection strength of the sealing gasket 301 can be increased.

[0043] Embodiment 4

[0044] The compressed gas device 4 includes a compressed gas source 401 and a pipeline 402. One end of the pipeline 402 is in communication with the compressed gas source 401, and the other end of the pipeline 402 passes through the gland 204 and the sealing gasket 301 to communicate with the inner ring of the steel ring.

[0045] Specifically, the compressed gas source 401 can be an air compressor or the like, which is connected to the top plate 201 or placed outside the box body 1. The pipeline 402 can be a hose that passes through the gland 204 and the sealing gasket 301 to communicate with the inner ring of the steel ring. During the rising and falling of the gland 204, the pipeline 402 composed of the hose can be bent accordingly to adapt to the position change of the gland 204.

[0046] Working mode and principle of the device:

[0047] In operation, the air cylinder 202 is ventilated to extend the telescopic rod 203 to press down the gland 204, fix the steel ring between the gland 204 and the bottom plate 205 in the box body 1, and make the oil liquid 5 liquid surface higher than the steel ring, and the upper and lower end surfaces of the steel ring are respectively provided with the sealing gasket 301 between the gland 204 and the bottom plate 205 to seal, and then the compressed gas source 401 is opened to pass the compressed gas to the inner ring of the steel ring through the pipeline 402. Since the upper and lower ends of the inner ring of the steel ring are sealed by the sealing gasket 301, the compressed gas can only enter the pores (i.e. oil channels) in the inner ring wall of the steel ring, and escape from other positions of the steel ring through the pores. After escaping, these gases enter the oil liquid 5 outside the steel ring, form bubbles and float to dissipate, so that the number of bubbles on the surface of the oil liquid 5 in the box body 1 can be observed to judge the pore condition in the steel ring, and then judge the air permeability state of the steel ring, so as to realize the detection of the air permeability of the steel ring.

[0048] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for part or all of the technical features. Such modifications or substitutions do not change the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
