[0019] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0022] This invention discloses a quartz mesh preparation device, which can solve the technical problem of large differences in the longitudinal and transverse mechanical properties of fibers in the existing quartz fiber mesh production process, thereby improving the mechanical properties of the product.

[0023] The technical solution of this application will be described in detail below through specific embodiments: See Figure 1 , Figure 2 and Figure 3In a first aspect embodiment of this application, a quartz mesh fabrication apparatus is disclosed, comprising a cutting and conveying structure 2, a carding structure 3, a web-laying structure 4, a needle punching machine 5, and a winding machine 6. The cutting and conveying structure 2 is used to cut long fibers to a fixed length and convey the resulting short fibers. The carding structure 3 includes a fan 31 and a negative pressure adsorption machine 32 arranged sequentially. The fan 31 receives the short fibers and blows them into the air, while the negative pressure adsorption machine 32 adsorbs the blown short fibers. The web-laying structure 4 includes an input curtain 41, a compensation curtain 42, a web-laying curtain 43, and an output curtain 44 arranged sequentially along the conveying direction of the short fibers. The compensation curtain 42 is disposed between the input curtain 41 and the web-laying curtain 43, and is used to control the direction in which the short fibers enter the web-laying curtain 43. The cutting and conveying structure 2, the carding structure 3, the web-laying structure 4, the needle punching machine 5, and the winding machine 6 are arranged sequentially along the conveying direction of the short fibers.

[0024] The quartz mesh fabrication apparatus disclosed in this embodiment blows the received short fibers into the air using a fan 31, and then uses a negative pressure adsorption machine 32 to adsorb the short fibers in the air, causing the short fibers to form a randomly arranged fiber web in three-dimensional space. This combing method fundamentally eliminates the orientation caused by the longitudinal arrangement of fibers in traditional mechanical combing, so that the fiber web has similar mechanical properties in both the longitudinal and transverse directions.

[0025] Compared to traditional mechanical carding methods, this carding structure 3 reduces direct frictional contact between metal components and brittle quartz fibers. In traditional processes, friction between metal components and fibers easily introduces metal particle contamination, severely affecting the purity and reliability of the product. The carding method of this device effectively reduces this contamination risk, improving product quality and performance.

[0026] Furthermore, by adjusting the intensity of the airflow and the strength of the negative pressure adsorption to disperse the short fibers after combing, the uniformity and fineness of the thin fiber web can be controlled. By synergistically adjusting the rotational speed of the impeller 31 and the intensity of the negative pressure adsorption, the dispersion and distribution of fibers during the web formation process can be precisely controlled.

[0027] Increasing the speed of impeller 31 can enhance the centrifugal force of the thrown airflow, allowing the fibers to be more fully dispersed and thrown to a farther area, forming a thinner fiber web with a wider width and more dispersed fiber distribution; decreasing the speed of impeller 31 will cause the fibers to be deposited more concentrated in the middle of the net curtain, which is suitable for producing nets with a narrower width or special structure.

[0028] The negative pressure adsorption intensity can be controlled by adjusting the working frequency of the negative pressure fan or the opening of the damper. Increasing the negative pressure adsorption intensity allows the fibers to be more tightly adsorbed onto the surface of the mesh curtain, forming a dense and flat thin fiber mesh. Decreasing the negative pressure adsorption intensity allows the fibers to form a more fluffy and three-dimensional structure on the mesh curtain. This adjustment method significantly improves the flexibility of the production process and the adaptability of the products, enabling the same equipment to produce high-quality quartz mesh products of various specifications.

[0029] By controlling the frequency of the reciprocating oscillation and the conveying speed of the thin fiber web, the areal density of the final fiber web can be adjusted. The stacked fiber web is composed of continuous triangles when viewed from above.

[0030] When the reciprocating frequency of the netting curtain 43 increases or the conveying speed of the thin fiber net decreases, more layers of thin fiber net will be stacked within the same length, thereby significantly increasing the thickness and areal density of the fiber net; conversely, if the reciprocating frequency of the netting curtain 43 is reduced or the conveying speed of the thin fiber net is increased, the fiber net will become thinner and its areal density will be reduced.

[0031] This flexible control method not only enables precise control over the thickness and areal density of the fiber web, but also ensures the uniformity and consistency of the fiber web under different production conditions, meeting the requirements of various product specifications. Furthermore, the stacked fiber web exhibits a continuous triangular structure when viewed from above. This structural feature further enhances the overall stability and strength of the fiber web, enabling it to better maintain its shape and performance during subsequent needle-punching reinforcement.

[0032] By adjusting the fiber feeding amount and the output speed of the fiber web after laying, the final areal density of the web can be controlled. Increasing the fiber feeding amount or decreasing the output speed of the fiber web will cause more fibers to accumulate in the unit area of ​​the web, thereby increasing the areal density. Conversely, decreasing the fiber feeding amount or increasing the output speed of the fiber web will make the web thinner and reduce the areal density. This achieves online, dynamic and precise control of the areal density of the fiber web, ensuring the high consistency and stability of the product.

[0033] In one embodiment, the cutting and conveying structure 2 includes a cutting component and a conveying component. Along the conveying direction of the short fibers, the cutting component is positioned in front of the conveying component, and the impeller 31 is positioned behind the conveying component.

[0034] First, the long fibers are cut into specified lengths using a cutting component. The cut short fibers then fall directly onto the conveyor component behind, which avoids the accumulation of short fibers.

[0035] In one embodiment, the cutting assembly includes a first guide wheel 23, a second guide wheel 24, a third guide wheel 21, and a roller cutter 22. The first guide wheel 23 and the second guide wheel 24 are spaced apart to form a first conveying channel, and the third guide wheel 21 is spaced apart from the first guide wheel 23 to form a second conveying channel. Along the conveying direction of the short fibers, the roller cutter 22 is located behind the second conveying channel and in front of the conveying assembly. The roller cutter 22 is used to cut the long fibers and guide the resulting short fibers into the conveying assembly.

[0036] During the production process, the long fibers are constrained by the guide wheels from the moment they enter the first conveyor channel, preventing fiber deviation and entanglement. Furthermore, the first guide wheel 23, the second guide wheel 24, and the third guide wheel 21 can tighten the long fibers, thus facilitating subsequent cutting.

[0037] In one embodiment, the roller cutter 22 includes a main shaft 221 and a plurality of dividing blades 222. The plurality of dividing blades 222 are spaced apart along the axial direction of the main shaft 221. The main shaft 221 is spaced apart from the third guide wheel 21 to form a cutting space, and the main shaft 221 is rotated so that the dividing blades 222 on the main shaft 221 cut the long fibers in the cutting space.

[0038] Multiple dividing plates 222 are arranged equidistantly along the axial direction of the main shaft 221, and the dividing plates 222 are circular in design. The arrangement of multiple dividing plates 222 along the axial direction of the main shaft 221 ensures that the fibers are evenly divided and combed as they pass through, effectively avoiding fiber aggregation and entanglement. Furthermore, the circular design of the dividing plates 222 further optimizes the fiber's passability, reduces fiber damage and breakage during the dividing process, and thus ensures the integrity and uniformity of the fibers.

[0039] A rotary cutting method is used to achieve fixed-length cutting, and fine division ensures uniform distribution of short fibers. This process, achieved through a combination of rotary cutting and uniform fiber feeding, ensures precise consistency in fiber cutting length. The cut short fibers are not simply collected; instead, a homogenizing mechanism distributes them evenly and loosely across the entire width of the machine, laying a solid foundation for the uniform areal density of the final product from the outset.

[0040] Compared to the traditional straight-blade cutting method followed by manual collection and even distribution, the rotary cutting method is not only more efficient but also allows for appropriate design of the number of blades to accommodate different fiber lengths. It also avoids contamination and unevenness that may result from manual intervention, enabling continuous and automated production and significantly improving production efficiency and product consistency.

[0041] In one embodiment, the conveying assembly includes a conveyor belt 25 and a plurality of baffles 26, the plurality of baffles 26 being spaced apart on the conveyor belt 25, and a grid 27 being formed between two adjacent baffles 26.

[0042] Multiple baffles 26 are spaced apart on the conveyor belt 25 to form grids 27, each grid 27 capable of holding a certain amount of short fibers. This structure provides relatively independent conveying space for the short fibers, keeping them in a relatively fixed position during conveying and preventing them from scattering, piling up, or tangling on the conveyor belt 25. For example, during high-speed conveying, without the constraint of the grids 27, the short fibers might scatter due to airflow or equipment vibration, resulting in uneven fiber reception in subsequent processes.

[0043] In one embodiment, the combing structure 3 further includes a cylinder 33, a plurality of working rollers 34, and a plurality of stripping rollers 35. The cylinder 33 is disposed between the cutting conveyor structure 2 and the impeller 31, and the diameter of the cylinder 33 is larger than the diameter of the impeller 31. The plurality of working rollers 34 and the plurality of stripping rollers 35 are all spaced apart on the working section, and at least one stripping roller 35 is disposed between two adjacent working rollers 34.

[0044] The fibers are initially combed and dispersed by the high-speed rotation of cylinder 33. Then, the working roller 34 further combs the fibers, making them smoother and more neatly arranged. The stripping roller 35 removes impurities and substandard fibers from the fibers, ensuring the purity and uniformity of the fibers. This not only improves the combing quality of the fibers but also enhances the mixing effect between the fibers.

[0045] In one embodiment, both the working roller 34 and the peeling roller 35 are configured in groups of five.

[0046] Five sets of working rollers 34 and stripping rollers 35 are used to comb the fibers. This number has been optimized to balance the combing effect and production efficiency. Too few rollers will result in the fiber bundles not being completely broken up and remaining in the fibers, while too many rollers may cause the fibers to be over-combed, damaged in length, and occupy too much installation space.

[0047] In one embodiment, the quartz mesh fabrication apparatus further includes a yarn storage structure 1, which comprises a warp density positioner 12 and a plurality of yarn bobbins 11. The warp density positioner 12 is provided with a plurality of through holes, each corresponding to one of the plurality of yarn bobbins 11. Long fibers are wound on the yarn bobbins 11 and pass through the corresponding through holes so that the long fibers enter the cutting and conveying structure 2.

[0048] By guiding the long fibers through the through holes, we can prevent the long fibers from tangling or crossing. The orderly arrangement of the fibers is conducive to the subsequent processing of the combing structure 3, making the combing process smoother and enabling the short fibers to be combed into a uniform fiber web more effectively.

[0049] By setting the spacing and number of through holes appropriately, the density of the warp fibers can be accurately adjusted according to product requirements, thereby ensuring that the warp density of the final quartz mesh meets the design standards.

[0050] In one embodiment, the yarn storage structure 1 further includes a guide roller 13, which is disposed between the yarn bobbin 11 and the warp density positioner 12. Along the conveying direction of the short fibers, the projection of the guide roller 13 falls on the warp density positioner 12.

[0051] During the conveying process, friction between long fibers and stationary components can easily lead to surface wear, fuzzing, and even breakage, affecting the integrity and performance of the fibers. However, the guide roller 13 can rotate, transforming the friction between the long fibers and the guide roller 13 into rolling friction as the fibers pass through it. Compared to sliding friction, rolling friction offers less resistance, significantly reducing wear on the contact surface between the long fibers and the guide roller 13. This effectively prevents damage to the long fibers caused by friction, ensuring their quality and strength.

[0052] By raising the position of the long fibers entering the through-hole using the guide roller 13, the long fibers can enter the through-hole of the warp-fitting positioner 12 at a more suitable angle and height. This avoids strong friction between the long fibers and the warp-fitting positioner 12 at the through-hole opening due to the mismatch in height between the long fibers and the through-hole. Strong friction can not only damage the long fibers but may also cause them to become blocked or entangled at the through-hole opening, affecting the normal transport of the long fibers.

[0053] In one embodiment, the through holes on the precision positioner 12 are arranged in multiple rows along the height direction, and multiple guide rollers 13 can be provided. The multiple guide rollers 13 are arranged one-to-one with the multiple rows of through holes, that is, each guide roller 13 guides the long fibers into the through holes of the corresponding height, thereby making the multiple long fibers more orderly.

[0054] This ensures that each long fiber accurately enters the designated through-hole along the predetermined path, preventing the fibers from crossing, tangling, or accidentally entering other through-holes during transport. For example, in a high-speed production environment, without this precise guidance, long fibers can easily deviate from their track due to airflow, equipment vibration, or other factors, leading to transport chaos and affecting the normal operation of subsequent processes.

[0055] In one embodiment, the transport and forming components in contact with the fibers are made of a contamination-resistant material. These components include a transport curtain made of leather or bamboo, and pressure rollers and needle cloth made of rust-resistant metal materials. By using these contamination-resistant materials, the present invention eliminates the risk of introducing metal impurities or foreign matter during the production process due to component wear, ensuring extremely high internal cleanliness of the quartz mesh product.

[0056] Through the above embodiments, this application has the following beneficial effects or advantages: The quartz mesh preparation device disclosed in this application achieves uniform spreading, three-dimensional arrangement, extreme uniformity and stable structure of quartz mesh by optimizing the cutting, meshing, stacking and reinforcement methods, which significantly improves production efficiency, product consistency and mechanical properties, enhances the flexibility of production process and product adaptability, and can produce high-quality quartz mesh in various specifications.

[0057] The technical solution adopted to achieve the purpose of this application is as follows: In the second aspect of this application, the present invention also discloses a method for preparing quartz mesh based on the quartz mesh preparation apparatus of any embodiment of the first aspect, comprising the following steps: The long fibers are cut using the cutting and conveying structure 2, and the resulting short fibers are conveyed to the combing structure 3 at the rear. The short fibers are thrown by the wind turbine 31 and then the short fibers in the air are adsorbed by the negative pressure adsorption machine 32 to form a three-dimensional random fiber web. The total thickness and areal density of the final fiber web are controlled by adjusting the ratio of the reciprocating speed of the web laying curtain 43 to the running speed of the output curtain 44. The fiber web of a specified thickness is reinforced by needle punching machine 5, and then wound up to a fixed length by winding machine 6.

[0058] The quartz mesh preparation method disclosed in this application uses a fan 31 to blow received short fibers into the air, and then uses a negative pressure adsorption machine 32 to adsorb the short fibers in the air, so that the short fibers form a randomly arranged fiber web in three-dimensional space. This combing method fundamentally eliminates the orientation caused by the longitudinal arrangement of fibers in traditional mechanical combing, so that the fiber web has similar mechanical properties in both the longitudinal and transverse directions.

[0059] In one embodiment, the method for preparing quartz mesh further includes the steps of: using the cylinder 33 of the combing structure 3 to drive the short fibers to rotate at high speed for preliminary combing and dispersion, then using the working roller 34 to further comb the fibers, and then using the stripping roller 35 to remove impurities from the short fibers.

[0060] On the one hand, the working roller 34 further refines the short fibers, making them smoother and more neatly arranged; on the other hand, the peeling roller 35 removes impurities and substandard fibers from the short fibers, thus ensuring the purity of the short fibers.

[0061] Specifically, the quartz fiber long yarn is drawn out from the yarn bobbin 11 on the yarn rack, and after being uniformly guided by the warp locator 12, it enters the cutting machine and is cut to a fixed length by the roller cutter 22. The cut short fibers are then evenly distributed through the fine grid drawer 27.

[0062] The fibers are initially combed and dispersed by the high-speed rotation of cylinder 33. Then, the working roller 34 further finely combs the short fibers, making them smoother and more neatly arranged. Impurities and substandard fibers are removed from the fibers by the stripping roller 35, ensuring the purity and uniformity of the short fibers. This not only improves the combing quality of the short fibers but also enhances the mixing effect between them. The short fibers are then conveyed to the carding and web forming machine, where they are thrown and dispersed by the impeller 31 and simultaneously adsorbed by the negative pressure adsorption machine 32, forming a three-dimensional randomly arranged thin fiber web.

[0063] The thin fiber web is conveyed to the web laying machine via the input curtain 41 and the compensation curtain 42. The web laying curtain 43 reciprocates and folds the thin fiber web onto the output curtain 44. The areal density of the fiber web is precisely controlled by adjusting the reciprocating frequency of the web laying curtain 43 and the conveying speed of the output curtain 44.

[0064] The laid-up fiber web is reinforced by the needle punching machine 5 to form a web with a certain strength; finally, the reinforced web is wound up to a fixed length by the winding machine 6 to complete the entire production process.
