Embodiment 1

[0023] Embodiment 1: as figure 1 , figure 2 with image 3 As shown, a spinneret detector related to the present invention includes a base 1, a support device, a light source 7, a light detection device, a drive device, a transmission device and a computer, and the base 1 is provided with a support arm 6; The support device described above is movably installed on the base 1 for fixing the spinneret 9 to be detected; the light source 7 is installed below the support arm 6 through a cantilever beam structure; the light detection device is installed on The light path emitted by the light source 7 is opposite to the position of the light source 7, and is used to detect the light emitted by the light source; the transmission device is connected with the support device; the drive device is connected with the Transmission device is connected, is used to drive the supporting device that is connected with described transmission device; Described computer comprises host computer 15 an...

Embodiment 2

[0040] Embodiment 2: This embodiment is roughly the same as Embodiment 1, and the difference is that the automatic control system in Embodiment 1 is omitted, that is, the drive device control card 14, the driver 17, the first proximity switch 51, the second proximity switch 52, the second proximity switch A detection piece 23 , a second detection piece 36 ; the automatic control actuators, that is, the first servo motor 41 , the second servo motors 24 and 31 , and the third servo motor 82 are also omitted. Compared with embodiment 1, embodiment 2 adopts manual operation mode. The inspection personnel manually move the first linear motion base 2 and the second linear motion base 3 to rotate the rotary base 4 to move the spinneret 9 to detect each spinneret hole.

[0041] It is not difficult to find that the present invention can not only manually detect the spinneret, but also automatically detect the spinneret. Through the function of the detection sheet and the proximity swit...

Abstract

The invention relates to a spinning plate detector, which comprises a supporting device and a light source, wherein the supporting device is used for fixing a detected spinning plate and is movably arranged; the light source is used for emitting light; the supporting device is connected with a first transmission device; a driving force transferred to the supporting device through the first transmission device enables the supporting device to move or rotate to move the spinning plate so that the light emitted by the light source is aligned with a spinning hole on the spinning plate, and whether the spinning hole is normal is judged according to whether the light emitted by the light source can pass through the spinning hole or according to the condition of the light passing through the spinning hole. The spinning plate detector has the advantages of convenient use, high detection efficiency, capability of automatically detecting the spinning plate, high detection precision and stable and accurate motion.

Description

technical field [0001] The invention relates to the field of spinneret detection, in particular to a spinneret detector. Background technique [0002] The function of the spinneret is to transform the viscous polymer melt or solution into a fine flow with a specific cross-section through the micropores, and solidify through a coagulation medium such as air or a coagulation bath to form filaments. [0003] The shape of the spinneret used in wet spinning is generally hat-shaped, disc-shaped or plate-shaped. The spinneret is provided with a through hole for connecting a filter or a fixed shaft, generally a central through hole is provided, and spinneret holes are arranged around the through hole. The spinneret works under higher temperature and pressure. It requires pressure resistance, corrosion resistance and sufficient mechanical strength, and is generally made of gold-platinum alloy or titanium, niobium, tantalum, stainless steel and other metals. Depending on the type o...
