Description

Technical Field

[0001] The invention belongs to the field of glass fiber mesh glue coating, and in particular relates to a glass fiber mesh glue coating machine. Background Art

[0002] Fiberglass mesh is a mesh material formed by weaving or braiding glass fiber filaments and then processing them. This material usually has the characteristics of high strength, light weight and corrosion resistance. Because of these characteristics, fiberglass mesh is widely used in different industries and scenarios.

[0003] In the production process of glass fiber mesh, in order to further improve the performance of the glass fiber mesh after weaving, the glass fiber mesh is generally coated with glue by a coating roller or by immersion in a coating tank.

[0004] Since the surface of the glass fiber mesh is densely covered with holes, when a coating roller is used to apply glue to the surface of the glass fiber mesh, glue can only be applied to the upper and lower surfaces of the glass fiber mesh, and it is difficult to effectively act on the inner wall of the holes of the glass fiber mesh. There is a blind spot for glue application, and the glue cannot be fully applied. If the glass fiber mesh is immersed in a coating tank for glue application, although the glass fiber mesh and the holes on its surface can be fully attached with glue, the glue may be retained in the holes of the glass fiber mesh, causing the holes on the surface of the glass fiber mesh to be blocked due to excessive residual glue, resulting in defects in the glass fiber mesh and affecting the appearance.

[0031] The following is combined with Figure 1-10 The present application is further described in detail.

[0032] Please refer to Figure 1 , Figure 3 and Figure 5A glass fiber mesh gluing machine comprises a box body 1, a sealing door is rotatably provided on the right side of the box body 1, two observation windows are provided on the sealing door, a drying chamber 2 and a gluing chamber 3 are respectively provided in the upper and lower parts of the box body 1, a feed port 10 and a discharge port 11 are provided on the left outer wall of the box body 1, the feed port 10 is connected with the gluing chamber 3, the discharge port 11 is connected with the drying chamber 2, a through hole 12 is provided between the gluing chamber 3 and the drying chamber 2, a glass fiber mesh 19 raw material passes through the feed port 10, the through hole 12 and the discharge port 11 in sequence, and a liquid level detector 9 is fixedly provided on the inner wall of the rear side of the gluing chamber 3. A conveying mechanism 4 for guiding the movement of the glass fiber mesh 19 is provided between the drying chamber 2 and the gluing chamber 3, and a dredging mechanism 5 for preventing the glass fiber mesh 19 soaked in glue is provided inside the gluing chamber 3. The staff opens the sealed door on the right side of the box body 1, and then inserts the glass fiber mesh 19 from the feed port 10. The glass fiber mesh 19 in the glue coating chamber 3 then enters the drying chamber 2 from the through hole 12, and then passes through the discharge port 11 to be connected with the external traction device. The glass fiber mesh 19 is soaked inside the lower end of the glue coating chamber 3 so that the glue can fully penetrate into the interior of the glass fiber mesh 19. At the same time, the dredging mechanism 5 can dredge the glass fiber mesh 19 that has been soaked in the glue coating chamber 3, ensuring sufficient soaking while avoiding blockage of the glass fiber mesh 19. Then, it is sent into the drying chamber 2 through the through hole 12 for drying, and finally sent out from the discharge port 11.

[0033] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The conveying mechanism 4 includes a plurality of first conveying rollers 41 rotatably arranged in the drying chamber 2, and the plurality of first conveying rollers 41 are staggered up and down. A plurality of second conveying rollers 42 are rotatably arranged at the upper end of the interior of the gluing chamber 3. Two buffer components 43 are arranged on the front and rear inner walls of the lower end of the gluing chamber 3. A tensioning roller 44 is rotatably connected between the two corresponding front and rear buffer components 43. An adjusting component 45 is connected to each of the two buffer components 43 on the left side, and the two buffer components 43 on the right side are fixedly arranged on the front and rear inner walls of the gluing chamber 3 respectively. The buffer assembly 43 includes a mounting seat 431, on which two third guide rods 432 are fixedly provided, and a mounting block 433 is movably inserted into the two third guide rods 432 on the same mounting seat 431. The surfaces of the third guide rods 432 are located on the upper and lower sides of the mounting block 433 and are sleeved with third springs 434. The ends of the two third springs 434 on the same third guide rod 432 that are away from each other are fixedly connected to the mounting seat 431. The tensioning roller 44 is rotatably arranged between the two corresponding front and rear mounting blocks 433. The two mounting seats 431 on the left are respectively connected to the corresponding adjustment assemblies 45 above them, and the two mounting seats 431 on the right are respectively fixedly connected to the front and rear inner walls of the glue coating chamber 3. After the glass fiber mesh enters the glue coating chamber 3 from the feed port 10, it is sequentially mounted on the second conveying roller 42 on the left, the two tensioning rollers 44 below, and the two second conveying rollers 42 on the upper right side, and then enters the drying chamber 2 through the through hole 12, and is sequentially mounted on multiple first conveying rollers 41, and then sent out from the discharge port 11. During the conveying process, the buffer component 43 can effectively buffer and protect the glass fiber mesh 19 to prevent the glass fiber mesh 19 from breaking and deforming due to a sudden increase in tension.

[0034] See also Figure 3 , Figure 4 and Figure 6 , the front and rear inner walls of the left end of the glue coating chamber 3 are both provided with sliding grooves, the adjusting component 45 includes a screw rod 451 rotatably set in the sliding groove, a slider 452 is threadedly connected to the screw rod 451, and two second guide rods 453 movably connected to the slider 452 are fixedly set in the sliding groove, and two third motors 454 are fixedly set on the left outer wall of the box body 1, and the output shaft of the third motor 454 is fixedly connected to the left end of the screw rod 451.

[0035] In order to facilitate the control of the wetting time of the glass fiber mesh 19 and the glue, the third motor 454 drives the screw 451 to rotate so that the slider 452 can move left and right, so that the tensioning roller 44 on the left can approach or move away from the tensioning roller 44 on the right, and the distance between the two tensioning rollers 44 is controlled. In this way, when the conveying rate remains unchanged, the wetting time of the glass fiber mesh 19 in the glue can be controlled according to different types of glass fiber mesh 19, so as to avoid the problem that the glass fiber mesh has too little wetting time, resulting in uneven glue coating, or too long wetting time, increasing the risk of clogging of the mesh of the glass fiber mesh 19.

[0036] See also Figure 1 and Figure 3 The dredging mechanism 5 includes a beating assembly 51 disposed on the front and rear side walls of the glue coating chamber 3 and capable of cyclically beating the glass fiber mesh 19, and a plurality of licker-in rollers 52 are rotatably disposed on the front and rear side walls of the glue coating chamber 3, and a scraping assembly 53 is disposed below the plurality of licker-in rollers 52 in the glue coating chamber 3. The beating assembly 51 and the licker-in rollers 52 work together to dredge the glue liquid accumulated inside the mesh of the glass fiber mesh 19, and at the same time, the scraping assembly 53 is used to scrape off the glue liquid pounded out from the mesh.

[0037] See also Figure 2 , Figure 3 , Figure 5 and Figure 8 The beating component 51 includes a rotating shaft 511 rotatably arranged on the front and rear side walls of the glue coating chamber 3, spring telescopic rods 512 are fixedly arranged on the front and rear end surfaces of the rotating shaft 511, and the two spring telescopic rods 512 are fixedly connected to a connecting rod 513 at one end away from the rotating shaft 511, and a plurality of beating wheels 514 are rotatably arranged on the surface of the connecting rod 513, and the front and rear ends of the connecting rod 513 are rotatably connected to guide wheels 515, and a guide seat 516 is fixedly arranged on the front and rear inner walls of the glue coating chamber 3 above the rotating shaft 511, and the lower left end of the guide seat 516 is set as a slope 5161, and the guide wheel 515 is rollingly arranged on the slope 5161 of the guide seat 516, and a second motor 517 is arranged on the front outer wall of the box body 1, and the output shaft of the second motor 517 is fixedly connected to the front end of the rotating shaft 511.

[0038] In order to reduce the risk of clogging of the glass fiber mesh 19, after being transported and soaked between the two tensioning rollers 44, the glass fiber mesh 19 will gradually approach the flapping assembly 51. At this time, the second motor 517 drives the rotating shaft 511 to rotate, so that the spring telescopic rod 512 and the connecting rod 513 rotate. The rotation of the connecting rod 513 rotates the guide wheel 515. When the guide wheel 515 rotates and contacts the slope 5161 of the guide seat 516, the guide wheel 515 is squeezed by the slope 5161 of the guide seat 516, causing the spring telescopic rod 512 to contract. As the spring telescopic rod 512 rotates, the guide wheel 515 will separate from the guide seat 516. At this time, the pressure of the spring telescopic rod 512 is released and reset, driving the rotating connecting rod 513 to move quickly toward the glass fiber mesh 19 in the conveying process. The beating wheel 514 on the connecting rod 513 collides and beats the glass fiber mesh 19, causing the surface of the glass fiber mesh 19 to shake, shaking off the glue that may be accumulated in its mesh, reducing the glue that may exist in the mesh on the surface of the glass fiber mesh 19, and reducing the risk of blockage of the glass fiber mesh 19 after infiltration.

[0039] See also Figure 3 , Figure 5 , Figure 7 , Fig. 9 and Fig.10 The licker-in roller 52 includes a roller body 521 rotatably arranged on the front and rear side walls of the glue coating chamber 3, the rear ends of two adjacent roller bodies 521 are connected by a first pulley group, a plurality of grooves are provided on the surface of the roller body 521, a first spring 522 is fixedly arranged in the groove, an end of the first spring 522 close to the groove port is fixedly connected with a dredging needle 523, one end of the dredging needle 523 is slidably arranged in the groove, and the end of the dredging needle 523 away from the groove is set as a semicircular structure. Two stirring racks 6 are rotatably arranged inside the glue coating chamber 3 below the licker-in roller 52, the rear ends of the two stirring racks 6 are connected by a gear group, the rear end of the right stirring rack 6 is connected by a second pulley group, a first motor 7 is fixedly arranged on the front outer wall of the box body 1, and the output shaft of the first motor 7 is fixedly connected to the front end of the right stirring rack 6.

[0040] In order to further dredge the mesh holes on the surface of the glass fiber mesh 19, the first motor 7 drives the stirring frame 6 to rotate, stirs the glue in the glue coating chamber 3, and improves the fluidity of the glue. The stirring frame 6 can also flexibly abut against the glass fiber mesh 19, forcing the glue to quickly penetrate into the glass fiber mesh 19. At the same time, the stirring frame 6 rotates to cooperate with the second pulley group to rotate the roller body 521. The roller bodies 521 are connected by the first pulley group, so that multiple roller bodies 521 rotate counterclockwise at the same time, and some dredging needles on the surface of the roller body 521 are As 523 rotates, it will be directly inserted into the mesh holes on the surface of the glass fiber mesh 19 to dredge the mesh holes, and the dredging needle 523 is connected to the first spring 522, which can provide a certain buffer when the dredging needle 523 abuts against the solid area on the surface of the glass fiber mesh 19 to avoid hard contact. Multiple rollers 52 work together to ensure that most of the mesh holes on the surface of the glass fiber mesh 19 can be dredged by the dredging needle 523, thereby cooperating with the beating component 51 to greatly reduce the risk of clogging of the mesh holes on the surface of the glass fiber mesh 19.

[0041] See also Figure 3 , Figure 7 , Fig. 9 and Fig.10 The front and rear side walls of the glue coating chamber 3 and below the licker-in roller 52 are provided with sliding holes, the scraper assembly 53 includes a first guide rod 531 fixedly arranged in the sliding hole, a slide plate 532 is movably inserted on the first guide rod 531, a plurality of scrapers 533 are fixedly arranged between the opposite sides of the front and rear slide plates 532, the left and right end surfaces of the first guide rod 531 are sleeved with second springs 534, and a transmission assembly 8 is arranged between the roller body 521 near the second pulley group and the two slide plates 532. The transmission assembly 8 includes a rack 81 fixedly arranged on the slide plate 532, and a transmission gear 82 is fixedly arranged at both the front and rear ends of the roller body 521 near the second pulley group, and the transmission gear 82 is a notched gear, and the transmission gear 82 meshes with the corresponding rack 81 below.

[0042] In order to facilitate the scraping of the glue at the bottom of the glass fiber mesh 19 after the dredging treatment, when the roller body 521 rotates, the transmission gear 82 will rotate accordingly, and the transmission gear 82 will cooperate with the rack 81 to make the slide plate 532 move in the slide hole, so that the slide plate 532 drives the scraper 533 to move at the bottom of the glass fiber mesh 19 to scrape off the excess glue at the bottom of the glass fiber mesh 19. At the same time, since the transmission gear 82 is a notched gear, when the notch on the transmission gear 82 is aligned with the rack 81, the slide plate 532 will be reset under the action of the second spring 534, so that the scraper 533 on the slide plate 532 will quickly retreat. During the retreat process, the glue on the scraper 533 will quickly slide off the scraper 533. Compared with the traditional fixed scraper 533, the movable scraper 533 can make the glue slide off more easily after scraping the glue, and the scraping effect is better.

[0043] See also Figure 3 and Figure 6 A material storage box 13 is arranged on the left outer wall of the box body 1, and the material storage box 13 also has an observation window. A material delivery pipe 14 is fixedly connected between the bottom of the material storage box 13 and the glue coating chamber 3, and a solenoid valve is arranged on the material delivery pipe 14. A gas heater 15 is fixedly arranged on the top of the box body 1, and a first gas delivery pipe 16 is fixedly connected between the gas heater 15 and the drying chamber 2. A plurality of serpentine heat exchange tubes 17 are arranged inside the material storage box 13, one end of the serpentine heat exchange tube 17 is connected to the interior of the drying chamber 2, and a one-way valve is arranged on the end of the serpentine heat exchange tube 17 close to the drying chamber 2, and the other ends of the plurality of serpentine heat exchange tubes 17 pass through the bottom of the material storage box 13 and are commonly connected to a second gas delivery pipe 18, and the second gas delivery pipe 18 is connected to an external air pump. The depth of the glue liquid in the glue coating chamber 3 is higher than the liquid level detector 9 and lower than the lower end surface of the slider 452. The use of the glue liquid in the glue coating chamber 3 is detected by the liquid level detector 9. When the height of the glue liquid is lower than the liquid level detector 9, the solenoid valve on the feeding pipe 14 is controlled by the external controller to open to replenish the glue liquid in the glue coating chamber 3. The gas heater 15 heats the external air and sends it into the drying chamber 2 through the first gas pipe 16 to dry the glass fiber mesh 19 after the glue is coated. The hot air in the drying chamber 2 is extracted by the external air pump in conjunction with the serpentine heat exchange tube 17. The serpentine heat exchange tube 17 transfers the heat in the hot air to the glue liquid in the storage box 13 to preheat the glue liquid, thereby avoiding the problem of low temperature of the glue liquid when it enters the glue coating chamber 3, which leads to poor fluidity.

[0044] During specific operation, the glass fiber mesh 19 cooperates with the conveying mechanism 4 under the traction of the external traction device, first enters the inside of the gluing chamber 3 from the feed port 10, enters the glue solution after being guided by the second conveying roller 42 on the left, and then is conveyed by two tensioning rollers 44. During the conveying process, the glass fiber mesh 19 is fully infiltrated with the glue solution, and at the same time, the beating component 51 in the dredging mechanism 5 can cyclically beat the infiltrated glass fiber mesh 19, so that the glue solution accumulated in the mesh holes on the surface of the glass fiber mesh 19 is shaken off, and at the same time, multiple licker-in rollers 52 roll on the upper surface of the glass fiber mesh 19, and some dredging needles 523 on the surface of the licker-in roller 52 will be inserted into the mesh holes on the surface of the glass fiber mesh 19 for further dredging. The beating component 51 cooperates with multiple licker-in rollers 52 to ensure that the glass fiber mesh 19 is fully infiltrated while avoiding blockage of the glass fiber mesh 19. The glass fiber mesh 19 is then sent into the drying chamber 2 through the through hole 12 for drying treatment, and finally sent out from the discharge port 11.
