Description

Technical Field

[0001] This invention relates to the field of coating, and in particular to a gluing device for the production of quartz glass fiber cloth. Background Technology

[0002] In the production of quartz glass fiber cloth, coating (or impregnation) is a crucial step, used to impart specific properties to the fiber cloth, such as increased strength, improved weather resistance, enhanced adhesion to the matrix resin, or special functions (such as flame retardancy and insulation). Currently, the impregnation method is a widely adopted and highly efficient coating method in the industry. The equipment typically includes an impregnation tank containing the adhesive solution, a set of guide rollers, and extrusion rollers (or a scraper). The quartz glass fiber cloth continuously passes through the impregnation tank under tension control, completely immersing itself in the adhesive solution for thorough wetting. Excess adhesive is then precisely removed by the extrusion rollers, resulting in a uniform adhesive layer with controllable thickness on its surface. This method offers advantages such as continuous operation, high efficiency, and thorough wetting.

[0003] However, the aforementioned impregnation equipment has a significant drawback in actual operation: during discontinuous production or temporary shutdowns (such as changing fabric rolls, maintenance, or adjustments), the adhesive in the impregnation tank (especially those containing fillers or solid components) will gradually settle and stratify due to gravity. At this time, if some sections of the quartz glass fiber fabric remain immersed in the static adhesive, these sections will continue to absorb the adhesive and lose the dynamic control of the extrusion rollers, resulting in localized adhesive application that significantly exceeds process requirements (i.e., "over-impregnation"). Over-impregnation significantly reduces the inherent flexibility and drape of the fiber fabric, making it brittle. During subsequent curing, an excessively thick adhesive layer is prone to internal stress due to uneven curing, leading to cracking, warping, and weakening the interfacial bonding with the fibers. Simultaneously, uneven adhesive composition caused by settling (such as an imbalanced resin / filler ratio) will cause the adhesive layer properties (such as heat resistance, insulation, and bonding strength) in that area to deviate from standards, compromising product performance uniformity and batch stability. This not only wastes materials (which need to be scrapped or downgraded), but may also become a point of failure in subsequent processes, seriously affecting product quality and production efficiency. Summary of the Invention

[0004] Therefore, the technical problem this invention aims to solve is that when existing impregnation equipment stops, the settling of the adhesive solution can cause the soaked fiber cloth to absorb excessive adhesive, leading to problems such as adhesive layer cracking and uneven performance, which seriously affects product quality and production efficiency. This process defect not only increases the scrap rate but also causes subsequent process failures, making it a key bottleneck restricting production.

[0005] The above-mentioned technical problems are solved by the following technical solution: This invention proposes a gluing device for the production of quartz glass fiber cloth, including a feeding component, a glue-impregnating component, and a processing and winding component.

[0006] The impregnation component includes an adhesive tank and a support mounted above the adhesive tank. The support is equipped with a first roller and a second roller for guiding quartz glass fiber cloth into the adhesive tank. The first roller and the second roller are connected to both ends of the adhesive tank by connectors, which drive the two ends of the adhesive tank to rise asynchronously and descend automatically.

[0007] In a preferred embodiment of the gluing equipment for producing quartz glass fiber cloth according to the present invention: the connecting component includes a first gear and a first rack that cooperate with the first roller, and a second gear and a second rack that cooperate with the second roller.

[0008] The first rack and the second rack are not synchronized.

[0009] In a preferred embodiment of the gluing equipment for producing quartz glass fiber cloth according to the present invention: the lifting speed of the first rack is greater than that of the second rack, and the number of teeth between the first gear and the first rack and the second gear and the second rack is greater.

[0010] In a preferred embodiment of the gluing equipment for producing quartz glass fiber cloth according to the present invention: the first gear and the first rack are provided in two symmetrical sets, wherein the two first gears are respectively installed at the two ends of the first roller through electromagnetic clutches, and the first rack of each set meshes with the first gear.

[0011] In a preferred embodiment of the gluing equipment for producing quartz glass fiber cloth according to the present invention: the second gear and the second rack are provided in two symmetrical sets, wherein the two second gears are respectively installed at the two ends of the second roller through electromagnetic clutches, and the second rack of each set meshes with the second gear.

[0012] In a preferred embodiment of the gluing equipment for producing quartz glass fiber cloth according to the present invention: the bottom of the first rack and the second rack are configured as ball heads, and the side of the glue pool is provided with corresponding first receiving groove and second receiving groove. The ball head of the first rack is in the first receiving groove, and the ball head of the second rack is in the second receiving groove. The cross-sectional area of ​​the upper opening of the first receiving groove and the second receiving groove is larger than the cross-sectional area of ​​the first rack and the second rack, but smaller than the maximum cross-sectional area of ​​the ball head.

[0013] In a preferred embodiment of the gluing equipment for producing quartz glass fiber cloth according to the present invention: a first limiting groove and a second limiting groove are provided on the bracket, the first rack moves up and down in the first limiting groove, and the second rack moves up and down in the second limiting groove.

[0014] In a preferred embodiment of the gluing equipment for producing quartz glass fiber cloth according to the present invention: an elastic support is provided at the bottom of the glue tank, and multiple sets of the elastic support are provided, wherein the elastic support is a pneumatic cylinder or a spring.

[0015] In a preferred embodiment of the gluing equipment for producing quartz glass fiber cloth according to the present invention: the quartz glass fiber cloth extends into the glue pool through the first roller and exits from the glue pool along the second roller, and the first roller and the second roller rotate as the quartz glass fiber cloth moves.

[0016] In a preferred embodiment of the gluing equipment for producing quartz glass fiber cloth according to the present invention: the feeding component includes a detachable feeding cylinder to feed out the quartz glass fiber cloth, the processing and winding component includes various processing rollers and a winding cylinder, each of the processing rollers is used to guide the quartz glass fiber cloth and perform glue extrusion operation, and the winding cylinder winds up the glue-impregnated quartz glass fiber cloth.

[0017] The beneficial effects of this invention are as follows: it effectively solves the technical problems in traditional impregnation processes without the need for external power. When the equipment stops, the adhesive pool automatically descends under its own weight, separating from the quartz glass fiber cloth, thus avoiding the problem of excessively thick adhesive layers caused by prolonged immersion. This process is achieved through gears, racks, and the reversal of the first and second rollers.

[0018] When the equipment restarts, the glue tank rises at an angle due to the difference in the number of teeth between the two sets of gears. This movement causes the glue to slosh, effectively mixing any precipitated colloid. During normal operation, the gears continuously mesh with the rack to generate minute vibrations, preventing the glue from settling. The entire system relies entirely on mechanical structures to achieve its functions, which is not only simple and reliable but also avoids the energy consumption problems of traditional electric stirring solutions.

[0019] Furthermore, this design can be directly applied to existing equipment, requiring only the addition of a gear and rack linkage mechanism, making modification convenient. Compared to traditional solutions, this design significantly improves the reliability and economy of the equipment while ensuring the quality of the adhesive impregnation, providing a superior solution for the adhesive application process of quartz glass fiber cloth.

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0030] Reference Figures 1-5 This embodiment provides a gluing device for the production of quartz glass fiber cloth, including a feeding component 1, a glue-impregnating component 2, and a processing and winding component 3. The glue-impregnating component 2 includes a glue tank 21 and a support 22 installed above the glue tank 21. The support 22 is equipped with a first roller 23 and a second roller 24 for guiding the quartz glass fiber cloth into the glue tank 21. The first roller 23 and the second roller 24 are respectively connected to the two ends of the glue tank 21 through a connector 25, which is used to drive the two ends of the glue tank 21 to rise asynchronously and descend automatically.

[0031] In normal production, the substrate of this quartz glass fiber cloth coating equipment is continuously conveyed by the feeding component 1, enters the glue tank 21 through the first roller 23 for impregnation, and is then discharged by the second roller 24 into the subsequent processing stage. During this process, the movement of the substrate synchronously drives the rotation of the first roller 23 and the second roller 24, maintaining the glue tank 21 in a stable impregnation position through the connecting component 25. When the equipment stops, the substrate stops moving, causing the rollers to stop rotating. The glue tank 21 descends smoothly under its own weight, and the connecting component 25 reverses the rotation, allowing the substrate in the impregnation section to promptly detach from the glue solution, avoiding problems such as excessive glue layer thickness and uneven composition caused by prolonged static placement. This process is entirely achieved through the self-feedback of the mechanical structure, requiring no additional power intervention. When the equipment restarts, due to the difference between the two sets of connecting components 25, the glue tank 21 rises asynchronously, exhibiting a tilted upward movement. This asynchronous lifting and lowering generates liquid surface fluctuations that effectively agitate and flush away sediment at the bottom of the tank, completing the remixing of the glue solution in a short time. The entire workflow cleverly utilizes the characteristics of mechanical transmission, achieving integrated control of shutdown protection, restart mixing, and anti-sedimentation operation.

[0032] The feeding component 1 includes a detachable feeding cylinder 11 to feed the quartz glass fiber cloth. The processing and winding component 3 includes various processing rollers 31 and a winding drum 32. The processing rollers 31 are used for guiding the quartz glass fiber cloth and performing glue extrusion operations. The winding drum 32 winds up the glue-impregnated quartz glass fiber cloth. The quartz glass fiber cloth enters the glue tank 21 through the first roller 23 and exits from the glue tank 21 along the second roller 24. The first roller 23 and the second roller 24 rotate as the quartz glass fiber cloth moves.

[0033] This quartz glass fiber cloth coating equipment adopts a modular design, mainly consisting of three parts: feeding, dipping, and processing / winding, forming a continuous production line. The feeding component 1 uses a detachable feeding cylinder 11 for easy and quick replacement of raw material rolls, ensuring continuous production. The processing / winding component 3 is equipped with multiple sets of functional processing rollers 31, including guide rollers to ensure precise cloth positioning, extrusion rollers to control the adhesive layer thickness, and a winding cylinder 32 to automatically wind up the finished product, forming a complete post-processing procedure. In the dipping stage, the quartz glass fiber cloth is immersed in the adhesive pool 21 via the first roller 23, and after being fully soaked, it is discharged by the second roller 24, forming a stable dipping path. It is particularly noteworthy that the first roller 23 and the second roller 24 adopt a passive transmission design, with their rotation driven entirely by the friction of the moving cloth. This design simplifies the transmission structure and ensures strict synchronization between the roller speed and the cloth speed.

[0034] The connecting component 25 includes a first gear 251 and a first rack 252 that cooperate with the first roller 23, and a second gear 253 and a second rack 254 that cooperate with the second roller 24. The first rack 252 and the second rack 254 are not synchronized. The lifting speed of the first rack 252 is greater than that of the second rack 254, and the number of teeth between the first gear 251 and the first rack 252 and the second gear 253 and the second rack 254 is greater.

[0035] This section describes the crucial mechanical linkage connector 25 in the gluing equipment, which controls the lifting and lowering of the glue tank 21. Firstly, this connector 25 mainly consists of two sets: one set comprises a first gear 251 and a first rack 252 that mesh with the first roller 23; the other set comprises a second gear 253 and a second rack 254 that mesh with the second roller 24. These two sets of gears and racks look very similar, but there is a very important difference: they have different numbers of teeth.

[0036] When the equipment is running, the quartz fiberglass cloth drives the first roller 23 and the second roller 24 to rotate. Since both rollers are connected to gears via an electromagnetic clutch 26, each rotation of the rollers drives the gears to rotate. The key point here is that the first gear 251 has more teeth than the second gear 253. This means that at the same rotational speed, the gear with more teeth will drive the rack to move faster. Specifically, assuming the first gear 251 has 30 teeth and the second gear 253 has only 20 teeth, when both gears rotate once, the first rack 252 will be driven to move a distance of 30 teeth, while the second rack 254 will only move 20 teeth. Therefore, the upward speed of the first rack 252 is naturally faster than that of the second rack 254. This speed difference produces a clever effect: when the equipment restarts, the glue tank 21 does not rise flat, but rather rises to one side and falls to the other, forming a tilted state. This tilting action is particularly important because it causes the glue in the glue tank 21 to shake, just like shaking a bottle, which can re-stir the glue that has settled at the bottom.

[0037] After the first rack 252 rises to its highest position, the second rack 254 will continue to rise until the glue tank 21 returns to a horizontal position. This transition from tilted to horizontal will cause another sloshing of the glue, which is equivalent to a second stirring. The entire rising process is quick and will not affect normal production.

[0038] During normal production, the gear will gently "push" against the bottom tooth of the rack. Because the cloth is constantly moving and the roller is constantly rotating, the gear is constantly making this "push" motion. This causes the rack to move up and down slightly, causing the glue tank 21 to vibrate slightly. Although this vibration is very small, it is enough to prevent the glue from settling and keep the glue solution uniform.

[0039] In summary, this connector 25 achieves three important functions through two sets of gears and racks with different speeds: first, it automatically separates the glue pool 21 and the fabric when the machine stops; second, it automatically stirs the glue when the machine restarts; and third, it continuously prevents sedimentation during production. Moreover, the entire process is completed automatically by the mechanical structure without the need for additional motors or control systems, which is both reliable and cost-effective.

[0040] Two symmetrical sets of first gears 251 and first racks 252 are provided, wherein each of the two first gears 251 is mounted on the two ends of the first roller 23 via an electromagnetic clutch 26, and the first rack 252 in each set meshes with the first gear 251. Two symmetrical sets of second gears 253 and second racks 254 are provided, wherein each of the two second gears 253 is mounted on the two ends of the second roller 24 via an electromagnetic clutch 26, and the second rack 254 in each set meshes with the second gear 253.

[0041] This section describes the specific arrangement of the gear and rack mechanism in the connecting piece 25. First, this mechanism employs a symmetrical design. At each end of the first roller 23, there is an identical first gear 251, mounted on the first roller 23 via an electromagnetic clutch 26. Each first gear 251 is paired with a first rack 252. Similarly, at each end of the second roller 24, there is a second gear 253, also mounted via an electromagnetic clutch 26. Each second gear 253 is paired with a second rack 254.

[0042] The two sets of symmetrically arranged gears and racks are mainly to ensure that the force on both ends of the glue pool 21 is even. If only one side is equipped with gears and racks, the glue pool 21 may tilt and get stuck when it is raised and lowered. Equipping both sides can maintain balance and allow the glue pool 21 to move up and down smoothly.

[0043] Regarding the electromagnetic clutch 26: When the first roller 23 or the second roller 24 rotates forward (in the direction the fabric is moving forward), the clutch locks, transmitting the roller's rotation to the gears. This allows the gears to drive the rack upwards. However, when the rack needs to descend, the machine stops, de-energizing the electromagnetic clutch, causing it to slip and allowing the gears to idle. This allows the glue tank 21 to slowly descend under its own weight. The advantage of this design is that it reliably lifts the glue tank 21 during operation and allows it to descend freely when the machine stops. It operates completely automatically without additional control, with both sides moving synchronously to ensure the glue tank 21 remains stable. Both sets of gears and racks use the same design, but it's important to note that the first gear 251 has more teeth than the second gear 253 to create a speed difference, achieving the aforementioned effect of the glue tank 21 tilting upwards.

[0044] The bracket 22 has a first limiting groove 221 and a second limiting groove 222. The first rack 252 moves up and down in the first limiting groove 221, and the second rack 254 moves up and down in the second limiting groove 222.

[0045] The design of the first limiting groove 221 and the second limiting groove 222 is a key structure to ensure the smooth lifting and lowering of the glue tank 21. The first limiting groove 221 and the second limiting groove 222, which are set on the bracket 22, are vertical guide rails tailored for the rack, so that the first rack 252 and the second rack 254 can only move up and down within the set track. This guiding design not only ensures the verticality of the rack movement and avoids jamming caused by skew, but also prevents mechanical overload by limiting the stroke range. When the glue tank 21 performs a special tilting and rising action, the limiting grooves on both sides ensure that the rack moves synchronously and accurately, so that the glue tank 21 tilts at a predetermined angle and then returns to horizontal, thereby achieving effective mixing of the glue. This simple and reliable structural design maintains the operational stability of the equipment and ensures the precise execution of the process actions.

[0046] An elastic support 28 is provided at the bottom of the glue tank 21. Multiple sets of elastic support 28 are provided. The elastic support 28 is a pneumatic cylinder or a spring.

[0047] The elastic support components 28 at the bottom of the glue tank 21 are the key buffer device for achieving smooth lifting and lowering of this equipment. Multiple sets of pneumatic cylinders or springs are evenly distributed at the bottom of the glue tank 21, acting like a "shock absorption system" for the glue tank 21. When the equipment stops, these elastic support components 28 slowly release pressure, allowing the glue tank 21 to descend smoothly under its own weight, avoiding sudden drops that could damage the mechanical structure. When restarting, they provide progressive support force, working in conjunction with the lifting action of the gear rack to ensure the glue tank 21 rises smoothly. This design specifically considers the sloshing characteristics of the glue liquid, effectively absorbing the vibrations generated during the movement of the glue tank 21 through elastic buffering. This protects the mechanical structure and maintains the stability of the glue liquid, much like a car suspension, making the entire lifting process both smooth and controllable.

[0048] The bottom of the first rack 252 and the second rack 254 is set as a ball head 27. The side of the glue pool 21 is provided with a corresponding first receiving groove 211 and a second receiving groove 212. The ball head 27 of the first rack 252 is in the first receiving groove 211, and the ball head 27 of the second rack 254 is in the second receiving groove 212. The cross-sectional area of ​​the upper opening of the first receiving groove 211 and the second receiving groove 212 is larger than the cross-sectional area of ​​the first rack 252 and the second rack 254, but smaller than the maximum cross-sectional area of ​​the ball head 27.

[0049] The design of the ball joint 27 and the receiving groove is to allow the glue tank 21 to flexibly adjust its angle during lifting. Specifically, the ball joint 27 at the bottom of the rack can rotate freely within the receiving groove. When one end of the glue tank 21 rises to its highest point (e.g., the end of the first rack 252), while the other end (the end of the second rack 254) continues to rise, this ball joint 27 structure can automatically adjust its angle. The dimensions of the upper opening of the receiving groove are carefully designed: slightly thicker than the rack rod, allowing the rack to tilt slightly; but smaller than the maximum diameter of the ball joint 27, preventing it from dislodging. This is similar to the principle of a universal joint, allowing the glue tank 21 to generate the necessary tilt angle during lifting, ensuring smooth operation even if the lifting speeds on both sides are different. This design ensures that the glue tank 21 can complete the crucial tilting and mixing motions while preventing the mechanism from jamming, making it key to the reliable operation of the entire lifting system.

[0050] Reference Figures 1-5 The working process of the quartz glass fiber cloth coating equipment:

[0051] Normal processing: In the continuous production of quartz glass fiber cloth, the substrate is released from the feeding cylinder 11, enters the glue tank 21 for glue impregnation via the guide roller and the first roller 23, and is then discharged by the second roller 24. After being guided by the guide rollers of each processing roller 31 of the subsequent winding component 3 or the glue layer thickness is adjusted by the extrusion roller, it is then wound up. The glue tank 21 is suspended on the support 22 of the equipment by the first rack 252 and the second rack 254, and is buffered and supported by the bottom elastic support 28 (such as a pneumatic cylinder or spring). During normal operation, the movement of the substrate drives the first roller 23 and the second roller 24 to rotate, and drives the first gear 251 and the second gear 253 to rotate forward, keeping the first rack 252 and the second rack 254 in a high position, and the glue tank 21 is stably impregnated with glue. At the same time, because the teeth of the gears continuously mesh with the lowest teeth of the rack and are slightly lifted, the glue tank 21 generates high-frequency micro-amplitude vibration, which effectively prevents glue sedimentation.

[0052] Shutdown protection separated from glue tank 21: When processing stops, the substrate stops, and the first roller 23 and the second roller 24 stop rotating. At this time, the glue tank 21 slowly descends under its own weight, and the rack drives the gear to rotate in the opposite direction, which in turn drives the electromagnetic clutch 26 to rotate. The elastic support 28 provides cushioning to ensure that the glue tank 21 descends smoothly, allowing the quartz glass fiber cloth in the soaking section to quickly detach from the glue solution, avoiding local over-soaking, glue layer thickening, or component segregation caused by prolonged static placement. This mechanism requires no additional power and relies entirely on mechanical self-feedback to achieve shutdown protection, significantly improving product consistency.

[0053] Restarting Mixing and Anti-Sedimentation Control: Upon restarting, when the substrate drives the first roller 23 and the second roller 24 to rotate, it drives the first gear 251 and the second gear 253 to rotate. Since the first gear 251 has more teeth than the second gear 253, the first rack 252 rises faster, causing the glue pool 21 to be tilted (the first rack 252 end is higher and the second rack 254 end is lower). The glue liquid forms turbulence in the pool to wash away the sediment. When the first rack 252 reaches the upper limit position, the second rack 254 will continue to rise until the glue pool 21 returns to a horizontal position. At this time, the glue liquid in the glue pool 21 will roll from the second rack 254 end to the first rack 252 end in the opposite direction to impact, shaking again to avoid sedimentation. The entire lifting process is completed in a short time. It is necessary to achieve remixing of the adhesive and avoid the risk of adhesive breakage. After normal operation, the first gear 251 and the second gear 253 continuously lift the lowest teeth of the first rack 252 and the second rack 254 to maintain micro-vibration of the adhesive pool 21, further suppress filler sedimentation, and ensure the uniformity of the adhesive.

[0054] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
