Description

Technical Field

[0001] This invention relates to the field of fiber processing technology, and in particular to a pretreatment mixing and processing equipment for the production of aramid fibers. Background Technology

[0002] The function of a drawing frame is to improve the internal structure of the sliver, thereby increasing the uniformity of its long segments, reducing weight unevenness, straightening and paralleling the fibers in the sliver, reducing hooks, ensuring the fineness meets the specifications, and mixing different types or qualities of raw materials evenly to achieve the specified mixing ratio. Drawing frames are divided into two main categories according to the form of the drafting mechanism: roller drafting drawing frames and carding frames.

[0003] For fiber mixing pretreatment, multiple fiber bundles need to be guided into the drawing frame. The fiber bundles enter through the feed inlet to facilitate entry and prevent scratching damage from contact with the feed inlet sidewall. Generally, guide rings are installed at the feed inlet to guide the fiber bundles through. However, guide rings are ineffective for mixing multiple fiber bundles. Even after the fiber bundles enter the drawing frame, they may still scrape against the feed inlet sidewall. Furthermore, they lack the function of mixing and combing the fiber bundles to prevent them from becoming scattered during the mixing process.

[0004] To address these issues, this invention proposes a pretreatment mixing and processing equipment for aramid fiber production. Summary of the Invention

Detailed Implementation

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-9A pretreatment mixing and processing equipment for aramid fiber production includes a V-shaped inverted plate frame 1 and a front support plate 2 disposed at the front end of the V-shaped inverted plate frame 1. Mounting seats 3 are symmetrically fixed at the bottom end of the V-shaped inverted plate frame 1, and a window 11 is disposed on the back side of the V-shaped inverted plate frame 1. A top plate 4 is disposed at the top of the V-shaped inverted plate frame 1, and an arc-shaped carrier plate 6 is disposed on the top plate 4. Guide iron rings 7 are fixedly disposed at equal intervals on the front side of the arc-shaped carrier plate 6, and fiber bundles pass through the guide iron rings 7.

[0035] Please refer to the appendix to this plan. Figure 1 Appendix Figure 3 and attached Figure 7 This is the core of the technical problem solved by this solution. In this solution, front support frames 8 are symmetrically arranged on both sides of the front side of the V-shaped inverted plate frame 1 near the bottom. The front support frames 8 are connected to the auxiliary rotating shaft 9. A guide cylinder 92 is arranged on the auxiliary rotating shaft 9. Limiting discs 91 are symmetrically fixed at both ends of the guide cylinder 92. Mixing limiting grooves 93 are equidistantly arranged on the outer circumferential surface of the guide cylinder 92. The mixing limiting grooves 93 and the mixing auxiliary mechanism work together to perform mixing pretreatment on the fiber bundles. The mixing auxiliary mechanism includes a fiber bundle guide plate 1004, which is arranged on the front support plate 2.

[0036] During the pre-treatment of the fiber bundles, the fiber bundles pass through the guide ring 7 on the front side of the top plate 4, then through the fiber bundle guide plate 1004 at the corresponding position on the front support plate 2. Here, the fiber bundle guide plate 1004 and the guide ring 7 are set in the same number of sets. Then, the fiber bundles pass through the mixing limiting groove 93 at the corresponding position on the outer wall of the guide cylinder 92, and finally enter from the feed port of the drawing frame to carry out the mixing treatment of the fiber bundles.

[0037] Therefore, this solution uses the guide iron ring 7 in conjunction with the mixing limiting groove 93 on the outer side of the guide cylinder 92 and the mixing auxiliary mechanism on the front support plate 2 to perform mixing pretreatment on the fiber bundles. That is, through the cooperation of the fiber bundle guide plate 1004 and the mixing limiting groove 93, a binding effect can be provided on the fiber bundle guide during the mixing process to avoid scraping damage when the fiber bundle guide passes through the feed inlet of the drawing frame. It also has a mixing and combing effect on the fiber bundles to avoid the problem of multiple fiber bundles becoming scattered during the mixing process.

[0038] In actual operation, the use of the fiber bundle guide plate 1004 in the hybrid auxiliary mechanism is based on the attached... Figure 3-4As shown, the mixing auxiliary mechanism also includes a loading channel 1001 and auxiliary components; here, the loading channel 1001 is disposed in the front support plate 2, wherein an externally threaded tube 1002 is inserted into the loading channel 1001, and the externally threaded tube 1002 is fixedly disposed at one end of the fiber bundle guide plate 1004. The externally threaded tube 1002 is threadedly connected to an internally threaded positioning cap 1003, and the position of the fiber bundle guide plate 1004 is positioned by tightening the internally threaded positioning cap 1003, thereby adjusting the position of the fiber bundle guide plate 1004; that is, the fiber bundle guide plate 1004... One end of the externally threaded tube 1002 is inserted into the loading slot 1001 on the front support plate 2. The loading slot 1001 is rectangular and parallel to the upper and lower ends of the front support plate 2. The purpose of setting the loading slot 1001 is to control the parallel movement of the fiber bundle guide plate 1004. After the fiber bundle guide plate 1004 is moved to a certain position, the internally threaded positioning cap 1003 is tightened. That is, the tightened internally threaded positioning cap 1003 is pressed tightly against the inner wall of the front support plate 2, thereby realizing the positioning of the fiber bundle guide plate 1004.

[0039] In order to facilitate the mixing and conveying of the fiber bundles, the fiber bundle guide plate 1004 needs to be rotated to ensure that the auxiliary roller 1007 in the cavity 1005 of the fiber bundle guide plate 1004 comes into contact with the fiber bundles. In other words, the fiber bundles need to pass through the auxiliary roller 1007. Therefore, combined with the attached... Figure 5 and attached Figure 7 As shown, a receiving cavity 1005 is provided in the fiber bundle guide plate 1004; the receiving cavity 1005 is connected to the external threaded tube 1002, and the receiving cavity 1005 extends to one side of the fiber bundle guide plate 1004 and to one end of the fiber bundle guide plate 1004. An auxiliary roller 1007 is provided in the receiving cavity 1005; a docking slot 1008 is provided at the center of both ends of the auxiliary roller 1007, and the auxiliary roller 1007 is installed by a bearing threaded pin 1006, which provides support and rotation for the auxiliary roller 1007.

[0040] Therefore, after translating and adjusting the position of the fiber bundle guide plate 1004, the fiber bundle guide plate 1004 is then rotated and adjusted to a suitable position. The position of the fiber bundle guide plate 1004 is then locked by tightening the internal thread positioning cap 1003. Here, the fiber bundle passes through one side of the fiber bundle guide plate 1004 equipped with auxiliary rollers 1007, and the auxiliary rollers 1007 are equidistantly arranged in the receiving cavity 1005, with gaps between adjacent auxiliary rollers 1007. The 007 monomer can be rotated. The purpose of this is to allow the fiber bundle to have more contact with the outer axial surface of the auxiliary roller 1007 when it passes through the fiber bundle guide plate 1004. In other words, during the guiding and conveying of the fiber bundle, excessive frictional contact between the fiber bundle and the fiber bundle guide plate 1004 is minimized. The rotatable auxiliary roller 1007 of the monomer can also minimize frictional damage. This ensures the quality of the fiber bundle during the premixing process and the product quality during the subsequent mixing process through the drawing frame.

[0041] This solution addresses the use of the auxiliary roller 1007, and further details are provided in the appendix. Figure 7 and attached Figure 9 As shown, receiving grooves are evenly arranged on the outer ring surface of the auxiliary roller 1007, and auxiliary balls 1009 are movably embedded in the receiving grooves. The reason for evenly arranging auxiliary balls 1009 on the axial side of the auxiliary roller 1007 is that when the fiber bundle passes through the auxiliary roller 1007, it is possible that the fiber bundle may move along the axis of the auxiliary roller 1007 or move repeatedly when passing through the side wall of the auxiliary roller 1007. That is, when the fiber bundle is offset and shakes along the axis of the auxiliary roller 1007, the evenly arranged auxiliary balls 1009 in the opposite direction of its axis can also reduce friction damage to the fiber bundle and provide protection for the fiber bundle. In addition, the auxiliary roller 1007 is installed by the provided bearing threaded pin 1006, which makes the auxiliary roller 1007 easy to disassemble and facilitates the subsequent replacement and maintenance of the auxiliary roller 1007.

[0042] The fiber bundles passing through the guide plate 1004 finally enter the drawing frame through the mixing and limiting groove 93 outside the guide cylinder 92, according to the attached... Figure 1-2As shown, the fiber bundle guide plate 1004 and the mixing limiting groove 93 on the outer ring surface of the guide cylinder 92 have the same number of sets. The fiber bundle passes through the guide iron ring 7, then through the fiber bundle guide plate 1004 set on the front support plate 2, and finally through the mixing limiting groove 93 at the corresponding position on the outer ring surface of the guide cylinder 92. When the fiber bundle passes through the mixing limiting groove 93 on the guide cylinder 92, the equidistantly arranged mixing limiting groove 93 can correspond to multiple fiber bundles, that is, one fiber bundle passes through one mixing limiting groove 93, which provides a binding effect on the fiber bundle. On the one hand, when multiple fiber bundles are guided and mixed, they can be accurately entered into the feed port of the drawing frame, and the problem of scratching damage to the side wall of the feed port is avoided. On the other hand, the multi-strand guided and mixed fiber bundles can be combed to avoid the problem of adjacent fiber bundles becoming messy or even knotted during subsequent mixing.

[0043] Here, when the fiber bundles pass through the fiber bundle guide plate 1004 in the mixing auxiliary mechanism, dust and other impurities easily adhere to the fiber bundles during the guiding, mixing, and conveying process. To ensure the quality of subsequent mixing and processing, this solution uses an auxiliary component to provide a corresponding cleaning and absorption function for the dust and other impurities on the fiber bundles; and then, according to the attached... Figure 3-4 and appendix Figure 7-8 As can be seen, in this solution, the connection is made at the pipe opening of the externally threaded pipe body 1002 and the connecting pipe head 1101 at one end of the exhaust hose 1102. The auxiliary components include the exhaust hose 1102, the filter screen 1103, and the flow channel 1106. The exhaust hose 1102 is provided with a connecting pipe head 1101 at one end, and the connecting pipe head 1101 is threadedly connected to the externally threaded pipe body 1002. The exhaust hose 1102 extends outward from the window 11 on the back side of the V-shaped inverted plate frame 1. The filter screen 1103 is fixedly installed on the mounting plate 110. The inner wall of 4 is fixedly connected to the fiber bundle guide plate 1004 by mounting screws 1105, and is located at the cavity opening of the receiving cavity 1005 at one end of the fiber bundle guide plate 1004 to block the cavity opening of the receiving cavity 1005 at the end of the fiber bundle guide plate 1004; that is, when the fiber bundle passes the position of the auxiliary roller 1007 on the fiber bundle guide plate 1004, the exhaust hose 1102 has a cleaning and absorption function for dust and other impurities on the fiber bundle during the exhaust process.

[0044] The filter screen plate 1103 is disposed in the receiving cavity 1005. The side of the filter screen plate 1103 contacts the inner wall of the receiving cavity 1005. A set of filter screen plates is provided so that impurities absorbed from the fiber bundles enter the receiving cavity 1005 of the fiber bundle guide plate 1004 from the space between adjacent auxiliary rollers 1007, and then pass through the filter screen plate 1103 in the receiving cavity 1005 for filtration, so that the absorbed impurities adhere to the filter screen plate 1103 as much as possible. The filter screen plate 1103 is fixed to the inner wall of the mounting plate 1104, and the mounting plate 1104 is fixed to the end of the fiber bundle guide plate 1004 by mounting screws 1105, which allows the filter screen plate 1103 to be disassembled for easy disassembly and cleaning.

[0045] To minimize the impact of the auxiliary roller 1007 on the cleaning of the fiber bundles, according to the attached... Figure 9 As shown, this solution also uniformly provides flow channels 1106 in the auxiliary roller 1007. The flow channels 1106 are uniformly provided in the auxiliary roller 1007, and the openings of the flow channels 1106 are located on the side wall of the auxiliary roller 1007. The flow channels 1106 and the auxiliary balls 1009 are staggered. That is, the flow channels 1106 can provide gas flow for the cleaning of the fiber bundle, so that the auxiliary roller 1007 also has the function of gas flow, which ensures the adsorption and cleaning of the fiber bundle.
