Description

Technical Field

[0001] The utility model relates to the field of spinneret inspection, in particular to a spinneret microscopy instrument. Background Technique

[0002] The spinneret is an important device on a chemical fiber spinning machine. There are numerous spinneret holes with different shapes and sizes on the spinneret. The diameter of the spinneret holes is relatively small and the processing difficulty is relatively large. Detecting the spinneret holes to determine whether they meet the quality requirements is very important for the quality of the spun fiber products. In addition, during the chemical spinning process, the polymer spinning solution or melt passes through the spinneret holes on the spinneret and then solidifies through a coagulation medium such as air or a coagulation bath to form fibers with a specific cross-sectional shape. The spinneret may have problems such as blocked or eroded spinneret holes during use, resulting in faulty holes, which will affect the spinning quality. Therefore, before and during use, it is necessary to use a detection instrument to detect the spinneret holes of the spinneret and unclog the faulty holes. Currently, most detections of the spinneret are carried out by irradiating from the bottom with a strong light source or by magnifying detection with a microscope. However, the number of spinneret holes on the spinneret reaches thousands, the detection workload is huge, the detection efficiency is low, and the situation of missed detection is extremely likely to occur.

[0003] According to the disclosed patent CN215574727U, a spinneret microscopy instrument includes a workbench, a support column fixed at the rear side of the workbench, an image acquisition device connected to the support column, a display screen, and a position adjustment mechanism. The image acquisition device includes a CCD camera, an eyepiece, a main objective lens, an annular light source, and a secondary objective lens coaxially arranged from top to bottom. The CCD camera is connected to the display screen to display the image collected by the image acquisition device on the display screen. The spinneret tray for installing the spinneret is arranged above the workbench and connected to the position adjustment mechanism. The position of the spinneret tray in the horizontal direction is adjusted through the position adjustment mechanism. In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. There is a gap between the traditional spinneret push plate and the bottom light source, so when the bottom light source is used, it will irradiate the outside of the spinneret, which not only affects the light transmission effect of the spinneret holes on the spinneret, but also interferes with the detection of the spinneret holes on the spinneret. Moreover, the spinneret lacks fixation in the spinneret push plate during detection, so it is easy to move when adjusting the position of the spinneret, which will lead to repeated detection of the spinneret holes or missed detection of the spinneret holes on the spinneret, thereby affecting the detection efficiency and quality of the spinneret. Therefore, a new technical solution needs to be designed to solve this problem. Content of the Utility Model

[0017] 2. Through the combination of the air pump, the one-way valve, the exhaust pipe, and the electromagnetic valve, when the air pump inflates the inflatable sealing airbag, the one-way valve can cooperate to avoid the gas in the inflatable sealing airbag from being discharged. After the inspection of the spinneret, the gas in the inflatable sealing airbag is discharged through the exhaust pipe by starting the electromagnetic valve, thereby facilitating the removal of the spinneret from the inner cavity of the inflatable sealing airbag.

Detailed implementation manners

[0023] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0024] Embodiment 1: A spinneret microscope, see Figures 1 to 4 , including:

[0025] Adjustment mechanism, the adjustment mechanism includes a bottom plate 101, an adjustment groove 102 is opened in the middle of the surface of the bottom plate 101, a screw 103 is rotatably connected between the two sides of the inner cavity of the adjustment groove 102, an adjustment block 104 is slidably connected in the adjustment groove 102, and the adjustment block 104 is threadedly sleeved on the outside of the screw 103;

[0026] Light source mechanism, the light source mechanism includes a conical cylinder 201 installed on the adjustment block 104, the conical cylinder 201 is an opaque cylinder, a light source lamp 214 is installed at the bottom end of the inner cavity of the conical cylinder 201, and the light source lamp 214 is placed in the middle of the bottom end of the inner cavity of the conical cylinder 201;

[0027] Sealing mechanism, the sealing mechanism includes a mounting plate 202 installed on the outside of the conical cylinder 201, the surface of the mounting plate 202 and the surface of the conical cylinder 201 are on the same horizontal plane, an air pump 303 is installed at the bottom of the mounting plate 202, an inflatable sealing airbag 301 is installed on the inner wall of the conical cylinder 201, the inflatable sealing airbag 301 is an opaque airbag, and an inflation pipe 302 is communicated between the air outlet end of the air pump 303 and the inflatable sealing airbag 301;

[0028] Positioning mechanism. The positioning mechanism includes chutes 206 opened on both sides of the surface of the mounting plate 202. Sliders 207 are slidably connected in both chutes 206. Support plates 203 are fixedly connected to the tops of both sliders 207. Connecting rods 204 are fixedly connected to the opposite ends of both support plates 203. V-shaped clamping plates 205 are fixedly connected to the opposite ends of both connecting rods 204. A limiting groove 210 is opened at the front end of the mounting plate 202. Adjusting chambers 209 are opened on both sides of the inner cavity of the limiting groove 210. The two adjusting chambers 209 are respectively communicated with the two chutes 206. A bidirectional lead screw 211 is rotatably connected between the two sides of the inner cavity of the limiting groove 210. Limiting blocks 212 are slidably connected to both sides of the inner cavity of the limiting groove 210. And the two limiting blocks 212 are respectively thread sleeved on the outer sides of both sides of the bidirectional lead screw 211. Guide rods 208 are fixedly connected between the two limiting blocks 212 and the two sliders 207 respectively. During operation, a part of the spinneret to be detected is placed at the opening at the top of the conical cylinder 201. Then, the bidirectional lead screw 211 is rotated. In cooperation with the limiting block 212 guiding and moving in the limiting groove 210 and the guide rod 208, the two V-shaped plates are simultaneously driven to move towards the spinneret to limit spinnerets of different sizes. Since the two V-shaped plates move synchronously, the spinneret can be positioned in the middle of the inner side of the conical cylinder 201. Then, the air pump 303 is started to inflate the inflatable sealing airbag 301 with gas to expand and fit on the outer side of the spinneret, thereby increasing the connection tightness between the inner side of the conical cylinder 201 and the outer sides of spinnerets of different sizes, and thus avoiding the light source irradiated by the light source lamp 214 during the detection of the spinneret from shining on the outer side of the spinneret. This not only improves the light transmission effect of the spinneret holes on the spinneret, but also avoids the light source outside the spinneret interfering with the detection of the spinneret holes. And during the detection, by rotating the screw rod 103, the detection position of the spinneret can be adjusted. At the same time, since the spinneret is positioned during the detection, it is avoided that the spinneret moves repeatedly during the adjustment of the spinneret position to detect the spinneret holes on the spinneret or miss the detection of the spinneret holes on the spinneret, thereby improving the detection efficiency and quality of the spinneret.

[0029] Specifically, refer to Figure 4 , a one-way valve 304 is installed on the air charging pipe 302. An exhaust pipe 305 is communicated with the air charging pipe 302 on one side of the one-way valve 304. An electromagnetic valve 306 is installed on the exhaust pipe 305. When the air pump 303 inflates the inflatable sealing airbag 301, in cooperation with the one-way valve 304, it can avoid the gas in the inflatable sealing airbag 301 from being discharged. When the spinneret is detected, by starting the electromagnetic valve 306, the gas in the inflatable sealing airbag 301 is discharged through the exhaust pipe 305, so as to facilitate taking out the spinneret from the inner cavity of the inflatable sealing airbag 301.

[0030] Further, refer to Figure 1, a rectangular column 401 is installed on one side of the bottom plate 101. A rectangular frame 402 is sleeved outside the rectangular column 401. A fixing rod is installed on one side of the rectangular frame 402, and the other end of the fixing rod is installed with an image acquisition device 501. The image acquisition device 501 includes a CCD camera 502, an eyepiece 503, a main objective lens 504, an annular light source 505, and an auxiliary objective lens 506. The CCD camera 502, the eyepiece 503, the main objective lens 504, the annular light source 505, and the auxiliary objective lens 506 are installed in sequence from top to bottom. One end of the rectangular frame 402 is penetrated by a fixing bolt 403. The fixing bolt 403 is threadedly connected to the rectangular frame 402 and contacts the surface of the rectangular column 401. The CCD camera 502 is connected to a display screen (prior art, not marked in the figure) through a data cable, and the situation of the spinneret holes can be directly and clearly displayed on the display screen, thereby improving the effect of spinneret hole detection. And by turning the fixing bolt 403, it is convenient to adjust the position of the rectangular frame 402 on the rectangular column 401, and thus it is convenient to adjust the height of the image acquisition device 501 when in use.

[0031] It should be noted that, referring to Figure 2 and Figure 3 , one end of the screw rod 103 penetrates through the adjustment groove 102 and is placed on one side of the bottom plate 101. A first handwheel is fixedly connected to the screw rod 103 outside the bottom plate 101. One end of the bidirectional lead screw 211 penetrates through the limit groove 210 and is placed on one side of the mounting plate 202. A second handwheel 213 is fixedly connected to the bidirectional lead screw 211 outside the mounting plate 202. Through the settings of the first handwheel and the second handwheel 213, it is convenient for personnel to hold by hand, and thus it is convenient for personnel to manually rotate the screw rod 103 and the bidirectional lead screw 211 to adjust the spinneret plate and position and disassemble the spinneret plate.

[0032] It should be noted that, referring to Figure 1 , anti-slip pads 601 are fixedly connected to the opposite ends of the two V-shaped clamping plates 205. The anti-slip pads 601 are used to increase the friction force between the V-shaped clamping plates 205 and the outside of the spinneret plate, thereby improving the stability of positioning during spinneret plate detection.

Their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.
