Description

Technical Field

[0001] The invention relates to the technical field of spinning equipment, in particular to a testing device for an annular wind tube used for spinning. Background Art

[0002] The spinning ring is an equipment component used in the fiber manufacturing process in the textile industry. It is usually installed on a spinning machine, especially in the production of chemical fibers, such as polyester, nylon, etc. The main function of the spinning ring is to provide a uniform wind field to help cool, straighten and shape the fibers. During the spinning process, the molten polymer is extruded through the small holes of the spinneret to form filaments. When these filaments leave the spinneret holes, they need to be cooled quickly to solidify and form. The spinning ring can generate an airflow around the filaments through the annular air outlets. This airflow not only helps to cool quickly, but also prevents the fibers from entanglement, ensuring fiber quality and production efficiency.

[0003] During the production and transportation processes, the wire mesh air outlet surface of the inner wall of the annular wind tube may be damaged, which will cause the annular wind tube to be unable to provide a uniform wind field, affecting the fiber quality and production efficiency. Therefore, it is necessary to perform a wind pressure test on the annular wind tube after it is assembled. The test device in the prior art is relatively cumbersome to disassemble and assemble the annular wind tube, which affects its detection efficiency. Therefore, a testing device for annular wind tube for spinning is proposed to solve the above problem. Summary of the invention

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] Embodiment 1:

[0020] like Figure 1-Figure 5 As shown, the present invention discloses a spinning annular wind tube testing device, comprising an annular wind tube 2, a columnar shell 1 and a wind pressure detection sensor 3, the bottom of the columnar shell 1 is fixedly connected with a conical guide shell 4 connected thereto, a rectifying assembly 5 is arranged at the bottom of the columnar shell 1, a truncated pedestal seat 6 adapted to the annular wind tube 2 is arranged at the top center of the rectifying assembly 5, the wind pressure detection sensor 3 is arranged on the inner wall of the columnar shell 1, the annular wind tube 2 is arranged inside the columnar shell 1, and the bottom thereof is tightly matched with the truncated pedestal seat 6, and a sealing assembly is arranged at the top of the columnar shell 1 7, the sealing component 7 is used for sealing between the columnar shell 1 and the top of the annular wind tube 2, an annular shell 8 is arranged on the top of the columnar shell 1, a linkage component 9 rotatably connected to the annular shell 8 is arranged inside the annular shell 8, a compression component 10 arranged radially at intervals is arranged inside the annular shell 8, the linkage component 9 drives the compression component 10 to move radially, the compression component 10 is used to fix the sealing component 7, a rectangular shell 11 connected to the annular shell 8 is arranged on the side of the annular shell 8, a driving component 12 is arranged in the rectangular shell 11, and the driving component 12 drives the linkage component 9 to rotate.

[0021] The annular air cylinder 2 is cylindrical, and the air enters from the side wall. The present application mainly detects whether the side wall of the annular air cylinder 2 is blocked or damaged.

[0022] The columnar shell 1 is a hollow cylindrical structure, and its inner diameter needs to be larger than the outer diameter of the annular wind tube 2. A conical guide shell 4 is arranged at the bottom of the columnar shell 1, a rectifier assembly 5 is arranged at the bottom of the columnar shell 1, and a truncated pedestal seat 6 is arranged on the rectifier assembly 5. During the actual detection, the annular wind tube 2 is inserted into the columnar shell 1 from above, and the lower end of the annular wind tube 2 is sealed with the truncated pedestal seat 6, and there is a gap between the annular wind tube 2 and the columnar shell 1. Then the sealing assembly 7 is used to seal the top of the annular wind tube 2 and the top of the columnar shell 1, while the inside of the upper end of the annular wind tube 2 is not sealed. An airflow with a certain air pressure is introduced into the bottom of the conical guide shell 4, and the airflow is evenly sent into the inside of the columnar shell 1 under the action of the rectifier assembly 5 and the conical guide shell 4, and the airflow passes through the annular wind tube 2 and is discharged from the inside of the annular wind tube 2 to the outside. In this process, an air pressure is formed between the columnar shell 1 and the annular wind tube 2, and the wind pressure detection sensor 3 can detect the value of the air pressure. When the annular wind tube 2 is normal and the air pressure value introduced from the bottom of the conical guide shell 4 is determined, the value detected by the wind pressure detection sensor 3 is determined or within a small fluctuation range. Therefore, if the detected wind pressure value is greater than the normal value, it means that there is a blockage in an area of ​​the annular wind tube 2, and if the detected wind pressure value is less than the normal value, it means that there is a damage in an area of ​​the annular wind tube 2.

[0023] In order to facilitate the fixing of the sealing component 7 on the top of the columnar housing 1, an annular shell 8 is arranged on the top of the columnar housing 1, and the linkage component 9 in the annular shell 8 is driven by the driving component 12 in the rectangular shell 11 to rotate. When the linkage component 9 rotates, the pressing component 10 moves radially to press the sealing component 7 to maintain the sealing of the sealing component 7 and the ends of the columnar housing 1 and the annular wind tube 2. This form can realize the rapid pressing and release of the sealing component 7, thereby facilitating the replacement of the annular wind tube 2 and improving the test efficiency.

[0024] In order to allow the airflow entering from the conical guide shell 4 to enter the cylindrical shell 1 stably and evenly, a rectifying assembly 5 is provided. The rectifying assembly 5 comprises an outer ring 501, spokes 502, an inner ring 503, a flow splitting cone head 504 and a non-woven fabric 505. The inner wall of the cylindrical shell 1 near its bottom end is fixedly connected with the outer ring 501, the inner part of the outer ring 501 is fixedly connected with spokes 502 distributed in an annular manner at equal distances, the ends of the spokes 502 are connected with the inner ring 503, the inner part of the inner ring 503 is fixedly connected with a flow splitting cone head 504 extending into the conical guide shell 4 and adapted to the conical guide shell 4, non-woven fabrics 505 bonded to both the outer ring 501 and the inner ring 503 are bonded between adjacent spokes 502, and the truncated cone seat 6 is arranged on the top of the flow splitting cone head 504.

[0025] The outer ring 501 and the inner ring 503 are connected by evenly distributed spokes 502, and the overall structure is stable. The outer ring 501 is connected to the lower end of the cylindrical shell 1, and the two are sealed. A diverter cone 504 is arranged inside the inner ring 503, and the diverter cone 504 extends downward into the conical guide shell 4, and the inner ring 503 and the diverter cone 504 are sealed. Then a non-woven fabric 505 is arranged in the area formed by the inner ring 503, the outer ring 501, and the spokes 502. After the airflow enters from the bottom of the conical guide shell 4, it is evenly diffused to the periphery under the action of the diverter cone 504, so that the airflow outside the diverter cone 504 is uniform and stable. Under the action of pressure, the airflow passes through the non-woven fabric 505, enters the cylindrical shell 1, and then passes through the annular wind tube 2. This form can make the airflow entering the cylindrical shell 1 more stable and uniform, and make the detection of wind pressure more stable.

[0026] The truncated pedestal seat 6 is made of rubber. The truncated pedestal seat 6 is made of rubber and can seal the bottom of the annular wind tube 2, with a better sealing effect. At the same time, an annular groove can be provided on the truncated pedestal seat 6, and the end of the annular wind tube 2 can be embedded in the annular groove, so that the annular wind tube 2 can be positioned in the cylindrical housing 1 to ensure that the annular wind tube 2 is at the center of the cylindrical housing 1.

[0027] The sealing assembly 7 includes a clamping ring 701, a first sealing gasket 702 and a second sealing gasket 703. The clamping ring 701 is adapted to the circular hole at the top of the columnar housing 1 and the top of the annular wind tube 2. The first sealing gasket 702 is arranged between the outer bottom of the clamping ring 701 and the top of the columnar housing 1, and the second sealing gasket 703 is arranged between the inner bottom of the clamping ring 701 and the top of the annular wind tube 2. A wedge-shaped chamfer is arranged at the outer edge of the clamping ring 701.

[0028] Because there needs to be a certain gap between the columnar shell 1 and the annular wind tube 2, and the gap is relatively large. However, the larger the gap, the more difficult it is to seal the sealing component 7 at the top. Therefore, the top of the columnar shell 1 is extended inward to form an annular step, and the inner diameter of the step is slightly larger than the outer diameter of the annular wind tube 2. Therefore, a stepped structure is formed between the top of the annular wind tube 2 and the upper surface of the step. Therefore, the clamping ring 701 of the sealing component 7 also presents a matching stepped structure. The outer lower surface of the clamping ring 701 is sealed with the step through the first sealing gasket 702, and the inner lower surface of the clamping ring 701 is sealed and connected to the top of the annular wind tube 2 through the second sealing gasket 703. A wedge-shaped chamfer is set on the outer side of the clamping ring 701, and this structure can facilitate the compression component 10 to hold it and improve the stability of the fit.

[0029] The linkage assembly 9 includes a worm gear ring and an arc-shaped hole 902. The annular shell 8 is internally rotatably connected to the worm gear ring. The surface of the worm gear ring is provided with arc-shaped holes 902 distributed in a circular shape and at equal distances. The distance between the arc-shaped holes and the center of the worm gear ring gradually decreases from one end to the other.

[0030] The compression assembly 10 includes a sliding rod 1001 and a linkage shaft 1002. The inner side of the annular shell 8 is radially slidably connected with the sliding rods 1001 which are distributed in an annular shape at equal distances and extend therein. One end of the sliding rod 1001 is fixedly connected with the linkage shaft 1002. The linkage shaft 1002 extends into the corresponding arc-shaped hole 902. The sliding rod 1001 is provided with a chamfer structure matching the wedge-shaped chamfer on the outer side of the clamping ring 701 at one end thereof close to the clamping ring 701.

[0031] The driving assembly 12 includes a handwheel shaft 1201 and a worm sleeve 1202. The handwheel shaft 1201 is rotatably connected inside the rectangular shell 11, and the handwheel shaft 1201 extends to the outside of the rectangular shell 11. The worm sleeve 1202 meshing with the worm gear ring is fixedly connected to the handwheel shaft 1201 inside the rectangular shell 11.

[0032] The linkage assembly 9 realizes movement under the power of the driving assembly 12, and finally drives the pressing assembly 10 to move. The handwheel shaft 1201 of the driving assembly 12 extends to the outside of the rectangular shell 11, and a handwheel can be set on the handwheel shaft 1201 to rotate the handwheel shaft 1201. When the worm sleeve 1202 on the handwheel shaft 1201 rotates with the handwheel shaft 1201, it drives the worm gear ring meshed with it, thereby realizing the rotation of the worm gear ring. When the worm gear ring rotates, the relative position of the arc-shaped hole 902 is changed, and when the position of the arc-shaped hole 902 changes. Since the slide bar 1001 of the compression assembly 10 is radially arranged on the annular shell 8, it can only slide radially on the annular shell 8, and the linkage shaft 1002 at the end of the slide bar 1001 is arranged in the arc hole 902, when the worm gear ring rotates and causes the arc hole 902 to change its position, since the linkage shaft 1002 cannot rotate with the arc hole 902, it can only change the position of the linkage shaft 1002 in the arc hole 902, and finally change the radial position of the linkage shaft 1002, so as to realize the radial movement of the slide bar 1001. When the slide bar 1001 moves toward the inside of the worm gear ring, the chamfered structure at the end of the slide bar 1001 cooperates with the wedge-shaped chamfer of the clamping ring 701, and the clamping ring 701 is pressed and held on the upper end of the columnar housing 1 and the annular wind tube 2, so as to realize the fixed connection of the clamping ring 701. When the worm moves toward the outside of the turbine gear ring 901, the sliding end is released from the clamping ring 701, so that the clamping ring 701 and the annular wind tube 2 can be disassembled, which makes the assembly and disassembly of the annular wind tube 2 simple and efficient, and greatly improves the detection efficiency.
