Embodiment 1

[0024] Embodiment 1: as figure 1 , figure 2 and image 3 As shown, a spinneret detection device related to the present invention includes a base 1, a linear motion base, a rotating base 4, a turntable 44, a support cylinder 5, a light source 7, a light detection device, a transmission device and a computer. The base 1 is provided with a support arm 6; the linear motion base is movably mounted on the base 1; the rotating base 4 is mounted on the linear motion base; the The turntable 44 is installed on the rotating base 4; the support cylinder 5 is installed on the turntable 44; the support cylinder 5 has a through hole 54, and the end of the through hole 54 is provided with Accommodate the grooved hole 55 of the spinneret 9 to be tested; the light source 7 is installed in the middle of the support arm 6 using a cantilever structure, and passes between the rotating base 4 and the linear motion base. The gap is located below the support cylinder 5; the rotating base 4 is prov...

Embodiment 2

[0043] 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 first detection piece 23, the second detection piece 36; also omitted the executive mechanism of automatic control, namely the first servomotor 41, the second servomotor (24, 31) and the third servomotor 82. Compared with embodiment 1, embodiment 2 adopts manual operation mode. The first linear motion base 2 and the second linear motion base 3 are manually operated by inspectors to rotate the rotary base 4 to move the spinneret 9 to detect each spinneret respectively.

[0044] It is not difficult to find that the present invention effectively prevents the motion base from exceeding the allowable movement range through the function of the detection sheet and the proximity switch, and avoids jamming o...

Abstract

The invention relates to a spinneret plate detecting device, which comprises a linear motion base, a rotary base, a rotary table, a support cylinder and a light source, wherein the linear motion base can be arranged in a linear motion mode, and is connected with a second transmission device; the rotary table can be relatively rotationally arranged on the rotary base which is arranged on the linear motion base; the rotary table is connected with a first transmission device; the support cylinder is provided with the through hole; the end part of the through hole is provided with a slot hole capable of accommodating a spinneret plate; the support cylinder is arranged on the rotary table; the light source is used for emitting light and is positioned under the support cylinder; the rotary baseis provided with a channel allowing the light emitted by the light source to pass through; and the channel is communicated with the through hole of the support cylinder. The spinneret plate detectingdevice has high detection precision and stable and accurate detection actions, and can detect the spinneret plate with small diameter; and one set of device can detect spinneret plates with differentdiameters.

Description

technical field [0001] The invention relates to the field of spinneret detection, in particular to a spinneret detection device. 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 th...
