Description

Technical Field

[0001] This invention relates to the field of fabric processing, specifically to a UV-resistant polyester fabric processing equipment and preparation method. Background Technology

[0002] The raw materials used in the preparation of UV-resistant polyester fabrics include powder additives. During transportation and storage, these powders are prone to agglomeration or the introduction of large particles. If these large particles enter the subsequent melt spinning system, they can clog the spinneret orifices, causing yarn breakage and fuzzing, severely affecting spinning stability and fiber quality, and even damaging the equipment. Therefore, it is necessary to screen the raw materials (powder additives) before preparing UV-resistant polyester fabrics.

[0003] Existing patent 201820670215.8 discloses a powder screening device, relating to the field of powder technology. This powder screening device includes an operating table. Supports are fixedly connected to the left and right sides of the upper surface of the operating table. A sliding groove is formed on one side of the upper end of each support. A support column is fixedly connected to the middle of the upper surface of the operating table. A rotating plate is movably connected to the upper end of the support column via a first bearing. A support rod is fixedly connected to one side of the upper end of the rotating plate via a second bearing. A screening box is fixedly connected to one side of the upper end of the support rod.

[0004] After raw material screening, they are usually only divided into qualified and unqualified products. Unqualified products may contain impurities and large particles, but existing technologies cannot quickly and accurately separate and export these impurities and large particles, resulting in poor screening effectiveness. Therefore, those skilled in the art provide a processing equipment and preparation method for UV-resistant polyester fabric to solve the problems mentioned in the background section.

The dual rotatable screening assembly of this application, through the setting of limiting impact components, can not only limit the rotation angle of the first frame and the second frame to avoid excessive rotation angle causing raw material leakage, but also accept the impact from the first frame and the second frame, thereby causing the first screen body and the second screen body to vibrate. The raw material is screened by the vibration generated by repeated inversion and impact, which effectively improves the screening effect.

[0025] 3. The material guiding and buffering mechanism provided in this application can buffer the raw materials falling from the first rotating chamber, avoiding the raw materials from falling directly onto the second screen body and causing a large impact.

[0027] 5. The bulk material assembly of this application uses two strip receiving plates to receive materials alternately in sequence, thereby buffering the raw materials falling directly from the crushing chamber. Then, the scraper is used to evenly and orderly sprinkle the raw materials downward, improving the uniformity of the bulk material and speeding up the screening speed. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] As mentioned in the background section of this application, research has found that the most commonly used screening tool is the sieve body, which is made of metal or plastic and has many small holes at the bottom. It can screen out impurities and lumps in the raw materials. The traditional screening method is to manually shake the sieve body to screen the raw materials. However, the existing screening equipment drives the sieve body to move by external force, which does not require manual intervention. But this screening equipment has certain defects in use. It is not efficient in screening raw materials and it is not easy to separate the screened impurities and large particles, which affects the next use.

[0039] To address the aforementioned shortcomings, this application discloses a UV-resistant polyester fabric processing equipment and preparation method. By incorporating a dual rotatable screening component and a separating material guiding mechanism, the screening effect on raw materials can be improved, facilitating the separate removal of impurities and large particles from the screening process, thus avoiding impact on future use.

[0040] The following will describe in detail, with reference to the accompanying drawings, how the solution of this application solves the above-mentioned technical problems.

[0041] Please see Figures 1-8 In this embodiment of the invention, a UV-resistant polyester fabric processing device includes a machine body 1. A feeding chamber 2 is located on the top surface of the machine body 1, and a crushing chamber 3 communicating with the feeding chamber 2 is located below it. The crushing chamber 3 contains crushing components, and a material dispersing chamber 4 is located below the crushing chamber 3. The material dispersing chamber 4 contains a material dispersing assembly, and a double rotatable screening assembly is located below the material dispersing chamber 4. A separating guide mechanism is located below the double rotatable screening assembly, cooperating with the rotatable screening assembly to separately remove impurities and large particles from the screened material. The double rotatable screening assembly and the separating guide mechanism improve the screening effect of the raw materials, facilitating the separate removal of impurities and large particles from the screened material, thus avoiding impact on future use.

[0042] In this embodiment, the dual rotatable screening assembly specifically includes: a first rotating cavity 5 located below the bulk material chamber 4; an intermediate cavity 6 communicating with the first rotating cavity 5 located below it; and a second rotating cavity 7 communicating with the intermediate cavity 6 located below it. A first frame 21 is rotatably connected inside the first rotating cavity 5, and a first screen body 22 is embedded on both sides of the top surface of the first frame 21. A second frame 23 is rotatably connected inside the second rotating cavity 7, and a second screen body 24 is embedded on both sides of the top surface of the second frame 23. A rotary motor 25 is fixedly connected to the outer side of the machine body 1 at positions corresponding to the first frame 21 and the second frame 23, and the output shaft of the rotary motor 25 is fixedly connected to the first frame 21 and the second frame 23. A material guiding buffer mechanism is provided inside the intermediate cavity 6. Limiting impact members are provided inside both the first rotating cavity 5 and the second rotating cavity 7 to limit the rotation angle of the first frame 21 and the second frame 23 and to receive impacts from the first frame 21 and the second frame 23. The dual rotatable screening assembly performs dual screening of raw materials through the first screen body 22 and the second screen body 24. At the same time, after the screening is completed, the first screen body 22 and the second screen body 24 can be flipped over to remove the large particles and impurities trapped on them.

[0043] In this embodiment, the limiting impact component specifically includes: two sets of telescopic grooves 32 arranged side-by-side on the inner walls of the first rotating cavity 5 and the second rotating cavity 7, each set containing four telescopic grooves 32 arranged in a rectangular pattern, and a matching telescopic block 33 movably connected inside each telescopic groove 32. A telescopic motor 34 is embedded on one inner wall of each telescopic groove 32, and the output shaft of the telescopic motor 34 is fixedly connected to the corresponding telescopic block 33. The dual rotatable screening assembly, through the limiting impact component, not only limits the rotation angle of the first frame 21 and the second frame 23 to prevent excessive rotation angle from causing material leakage, but also receives impacts from the first frame 21 and the second frame 23, thereby causing the first screen body 22 and the second screen body 24 to vibrate. The vibration generated by repeated inversion and impact effectively improves the screening effect by screening the raw materials.

[0044] In this embodiment, the material guiding and buffering mechanism specifically includes: several ropes 26 arranged horizontally side by side inside the intermediate cavity 6; slots 27 are provided on the inner walls of both sides of the intermediate cavity 6 corresponding to the positions of the ropes 26; and the two ends of the ropes 26 pass through the corresponding slots 27 and are fixedly connected to the lead weights 28; several evenly distributed sleeves 29 are movably connected to the outside of the ropes 26 inside the intermediate cavity 6; and four evenly distributed fan blades 30 are fixedly connected to the outer side of the sleeves 29; each sleeve 29 has a limiting diaphragm 31 on both sides, and the limiting diaphragm 31 is fixedly connected to the rope 26. Through the material guiding and buffering mechanism, the raw material falling from the first rotating cavity 5 can be buffered, preventing the raw material from directly falling onto the second screen body 24 and causing a large impact. At the same time, the material guiding and buffering mechanism can also disperse the falling raw material, ensuring that the raw material falls evenly into the second rotating cavity 7.

[0045] In this embodiment, the separating feeding mechanism specifically includes: a discharge chamber 8 located below the second rotating chamber 7; a discharge port 9 communicating with the discharge chamber 8 on one lower side; and an impurity outlet 10 communicating with the discharge chamber 8 on the other lower side. A rotating plate 35 is rotatably connected between the discharge port 9 and the impurity outlet 10, and the top edge of the rotating plate 35 contacts the inner wall of the discharge chamber 8. A stepper motor 36 is fixedly connected to the outer side of the machine body 1 at the position corresponding to the rotating plate 35, and the output shaft of the stepper motor 36 is fixedly connected to the rotating plate 35. The separating feeding mechanism can not only separate qualified raw materials and impurities for sequential discharge, but also make the impurity outlet 10 and the discharge port 9 independent of each other through the front and back surfaces of the rotating plate 35, avoiding secondary contamination.

[0046] In this embodiment, a triangular metal plate 37 is fixedly connected to the end of the rotating plate 35, and strong magnets 38 are embedded in the inner walls on both sides of the discharge chamber 8 at positions corresponding to the triangular metal plate 37. This arrangement improves the tightness of the connection between the rotating plate 35 and the inner wall of the discharge chamber 8.

[0047] In this embodiment, the bulk material assembly specifically includes: an upper strip-shaped receiving plate 15 located inside the bulk material chamber 4; first linear guide rails 13 are symmetrically fixedly connected to the inner walls of both sides of the bulk material chamber 4 below the upper strip-shaped receiving plate 15; and first linear motors 14 are movably connected to the outer surfaces of the first linear guide rails 13. Two first linear motors 14 are fixedly connected to the upper strip-shaped receiving plate 15, and a set of upper scrapers 16 are fixedly connected to one side of the upper strip-shaped receiving plate 15. The number of upper scrapers 16 is five, and the height of the bottom end face of the upper scrapers 16 gradually decreases from the side closest to the upper strip-shaped receiving plate 15 to the other side. The bottom end face of the upper scraper 16 furthest from the upper strip-shaped receiving plate 15 is perpendicular to the upper strip-shaped receiving plate 15. The top surface of the upper strip receiving plate 15 is flush with the top surface of the lower strip receiving plate 17. A lower strip receiving plate 17 is located below the upper strip receiving plate 15. Second linear guide rails 18 are symmetrically fixed to the inner walls of both sides of the material distribution chamber 4 below the lower strip receiving plate 17. Second linear motors 19 are movably connected to the outer surfaces of the second linear guide rails 18. Two second linear motors 19 are fixedly connected to the lower strip receiving plate 17. A set of five lower scrapers 20 are fixedly connected to one side of the lower strip receiving plate 17. The height of the bottom surface of each lower scraper 20 gradually decreases from the side closest to the lower strip receiving plate 17 to the other side. The bottom surface of the lower scraper 20 furthest from the lower strip receiving plate 17 is flush with the top surface of the lower strip receiving plate 17. The material distribution assembly receives material sequentially and alternately through the two strip receiving plates, thus buffering the raw materials falling directly from the crushing chamber 3. The scrapers then evenly and orderly sprinkle the raw materials downwards, improving the uniformity of the material distribution and accelerating the screening speed.

[0048] In this embodiment, the pulverizing component specifically includes a pulverizing roller 11 rotatably connected inside the pulverizing chamber 3. A drive motor 12 is embedded on one side of the pulverizing chamber 3, and the output shaft of the drive motor 12 is fixedly connected to the pulverizing roller 11. The pulverizing component can pulverize the raw materials to be screened, thereby breaking up large lumps and facilitating subsequent screening.

[0049] This application also discloses a method for preparing UV-resistant polyester fabric, which uses UV-resistant polyester fabric processing equipment and includes the following steps:

[0050] The raw materials to be screened are poured into the feed hopper 2, and the raw materials enter the crushing chamber 3 along the feed hopper 2;

[0051] The crushing component in the crushing chamber 3 breaks down the lumpy raw materials that are clumped together. The crushed raw materials fall into the material dispersing chamber 4. The specific working process of the crushing component is as follows: the drive motor 12 drives the crushing roller 11 to rotate. The crushing roller 11 crushes the falling raw materials, thereby breaking down the large lumps, which facilitates subsequent screening.

[0052] The material distribution assembly in the material distribution chamber 4 disperses the falling raw materials evenly downwards, and the raw materials enter the double rotatable screening assembly. The specific working process of the material distribution assembly is as follows: the raw materials fall along the crushing chamber 3 onto the upper strip receiving plate 15 of the material distribution chamber 4. After a preset time, the first linear motor 14 moves to the right along the first linear guide rail 13 according to a preset program. During this process, the upper strip receiving plate 15 passes the upper scraper 16, which scrapes down the raw materials above its bottom surface and scatters them below. At the same time, as the upper strip receiving plate 15 moves away, the raw materials falling from the crushing chamber 3 begin to fall onto the lower strip receiving plate 17. After the upper strip receiving plate 15 reaches the preset position on the right and is scraped off by the upper scraper 16, the upper strip receiving plate 15 begins to return to the initial position. After the upper strip receiving plate 15 returns to its initial position, it receives the material. Meanwhile, the second linear motor 19 moves to the left along the second linear guide rail 18. During this process, the lower strip receiving plate 17 passes the lower scraper 20, which scrapes off any material above its bottom surface and scatters it downwards. After the lower strip receiving plate 17 reaches a preset position on the left and has its material scraped off by the lower scraper 20, it begins its return journey to its initial position. Once the lower strip receiving plate 17 returns to its initial position, the upper strip receiving plate 15 begins to move to the right, and so on. This sequential alternating receiving by the upper and lower strip receiving plates 15 and 17 buffers the material falling directly from the crushing chamber 3. The scraper then evenly and orderly scatters the material downwards, improving the uniformity of the material and accelerating the screening speed. The entire process operates continuously and with high stability.

[0053] The dual rotatable screening assembly uses vibrations generated by repeated inversion and impact to screen raw materials, ultimately separating qualified materials from impurities. The specific workflow of the dual rotatable screening assembly is as follows: Raw materials enter the first rotating chamber 5 from the dispensing chamber 4 and fall onto the first frame 21. The corresponding rotary motor 25 of the first frame 21 operates, driving the first frame 21 to repeatedly rotate forward and backward within the first rotating chamber 5. During this process, the first screen 22 on the first frame 21 performs the first screening of the raw materials. The screened raw materials enter the second rotating chamber 7 along the intermediate chamber 6. It should be noted that the rotation of the first frame 21 is restricted by the telescopic block 33 of the limiting impact component, preventing it from rotating at a large angle. Furthermore, each time the first frame 21 rotates to its limit position, it collides with the telescopic block 33, and the vibration generated by the collision accelerates the screening speed of the first screen 22. After the raw materials enter the second rotating chamber 7, the rotary motor 25 drives the second frame 23 to repeatedly rotate forward and backward. During this process, the second frame 23 collides with the corresponding telescopic block 33, generating vibrations. The second screen 24 performs the second screening of the raw materials, and the screened raw materials fall into the discharge chamber 8 of the distribution guide mechanism.

[0054] The separating feeding mechanism sequentially discharges qualified raw materials and impurities. Specifically, after the screened raw materials enter the discharge chamber 8, they are fed out of the machine body 1 through the front of the rotating plate 35 along the discharge port 9. Once the qualified raw materials have been fed, the stepper motor 36 drives the rotating plate 35 to rotate. The rotating plate 35, originally attached to one side of the inner wall of the discharge chamber 8, rotates to attach to the other side of the inner wall. At this point, the discharge port 9 is blocked by the rotating plate 35, while the impurity outlet 10 is exposed. This design ensures that the impurity outlet 10 and the discharge port 9 are independent of each other through the front and back of the rotating plate 35, preventing secondary contamination. Furthermore, the triangular metal plate 37 and the corresponding strong magnet 38 are magnetically attracted together, which not only improves the tightness of the connection between the rotating plate 35 and the inner wall of the discharge chamber 8 but also enhances the structural stability of the rotating plate 35. Subsequently, the telescopic motor 34 of the limiting impact member in the first rotating cavity 5 retracts its output shaft, causing the telescopic block 33 to retract into the telescopic groove 32. Immediately afterward, the rotating motor 25 rotates the first frame 21 180 degrees, turning the originally upward-facing first screen body 22 downward, causing impurities and large particles on the first screen body 22 to fall into the second rotating cavity 7. Then, the telescopic motor 34 extends its output shaft again, returning the limiting impact member in the first rotating cavity 5 to its initial position. Next, the rotating motor 25 rotates the first frame 21 repeatedly in both directions. During this process, the first frame 21 collides with the corresponding telescopic block 33, generating vibrations that shake off stubborn impurities attached to the first screen body 22, causing them to fall into the second rotating cavity 7. After a period of time, the telescopic motor 34 of the limiting impact member in the second rotating chamber 7 retracts its output shaft, causing the telescopic block 33 to retract into the telescopic groove 32. Immediately afterwards, the rotating motor 25 drives the second frame 23 to rotate 180 degrees, turning the originally upward-facing second screen body 24 downwards, and the impurities and large particles on the second screen body 24 fall into the discharge chamber 8. Subsequently, the telescopic motor 34 extends its output shaft again, causing the limiting impact member in the second rotating chamber 7 to return to its initial position. Then, the rotating motor 25 drives the second frame 23 to rotate repeatedly in both directions. During this process, the second frame 23 collides with the corresponding telescopic block 33, generating vibrations, and the stubborn impurities attached to the second screen body 24 are shaken off and fall into the discharge chamber 8. Finally, the impurities that fall into the discharge chamber 8 are sent out of the machine body 1 through the impurity outlet 10.

[0055] It should be noted that when raw materials and impurities pass through the intermediate cavity 6, the material guiding and buffering mechanism inside the intermediate cavity 6 buffers the falling raw materials and impurities, preventing them from directly falling onto the second screen body 24 and causing a large impact. At the same time, the material guiding and buffering mechanism can also disperse the falling raw materials and impurities, ensuring that they fall evenly into the second rotating cavity 7. The specific working process of the material guiding and buffering mechanism is as follows: when the raw materials or impurities fall into the intermediate cavity 6, they first come into contact with the rope 26 and the sleeve 29 and fan blade 30 on the rope 26. The rope 26 and the sleeve 29 and fan blade 30 on the rope 26 receive the impact of the raw materials or impurities. If the impact force is too large, the rope 26 in the intermediate cavity 6 will shift downward and move along the slot 27 into the intermediate cavity 6. The external plumb bob 28 will rise. After the impact force disappears, the gravity of the plumb bob 28 will once again straighten and tighten the rope 26 in the intermediate cavity 6. This setting effectively avoids excessive impact force from causing a large burden on the rope 26. In addition, the impact force of raw materials or impurities will also drive the fan blades 30 to rotate, so that the corresponding sleeves 29 rotate synchronously between the limiting diaphragms 31 on both sides. During the rotation of the fan blades 30, the raw materials can be dispersed to ensure that the raw materials fall evenly into the second rotating cavity 7.

[0056] This invention, through its dual rotatable screening components and separating feed mechanism, improves the screening effect of raw materials, facilitating the separate removal of impurities and large particles from the screened material, thus preventing them from affecting future use. Furthermore, after screening, the first screen body 22 and the second screen body 24 can be flipped over to remove the large particles and impurities trapped on them.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
