DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The glass fiber spraying equipment according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figure 2-Figure 8As shown, the glass fiber spraying equipment provided by the embodiment of the present invention includes an outer mask 1, and a glass fiber transmission mechanism 2, a glass fiber coating mechanism 3 and an adhesive coating mechanism 4 arranged on the inner side of the outer mask 1, wherein the glass fiber transmission mechanism 2 is used to transmit the glass fiber to the glass fiber coating mechanism 3, and the adhesive coating mechanism 4 is used to apply adhesive to the glass fiber attachment surface so that the glass fiber is adsorbed to the attachment surface.

[0023] The glass fiber transmission mechanism 2 comprises a distribution tube 23 , which is arranged inside the outer cover 1 . A distribution spiral shaft 232 is arranged inside the distribution tube 23 , and a distribution outlet 234 is opened at the bottom of the distribution tube 23 .

[0024] The glass fiber coating mechanism 3 includes a coating roller 34 , which is disposed below the cloth outlet 234 , has a coating surface of a mesh structure, has a hollow interior, and has a negative pressure fan 36 disposed at one end of the coating roller 34 .

[0025] The adhesive applying mechanism 4 includes an application roller 45 which is provided on the front side of the coating roller 34 .

[0026] Specifically, when spraying glass fiber on the surface of a plate-like board, firstly, the device is placed flat on the upper surface of the board, and then the adhesive is applied to the coating roller 45, and the coating roller 45 applies the adhesive to the board.

[0027] The cut glass fibers are then fed into the distribution tube 23 , and are transmitted through the distribution screw shaft 232 inside the distribution tube 23 . The distribution screw shaft 232 discharges the glass fibers evenly from the distribution outlet 234 at the bottom of the distribution tube 23 , so that the glass fibers are evenly distributed on the surface of the coating roller 34 .

[0028] During the rotation of the coating roller 34, the negative pressure fan 36 causes the coating roller 34 to generate negative pressure, which can firmly adsorb the glass fibers on the surface of the coating roller 34 and reduce the flying of glass fiber debris. As the coating roller 34 continues to rotate, when the coating roller 34 rolls to contact the surface of the plate, the glass fibers on the coating roller 34 come into contact with the adhesive on the surface of the plate and are firmly attached to the surface of the plate. At the same time, the coating roller 34 can also compact the glass fibers coated on the plate to make the glass fibers adhere more evenly and tightly.

[0029] In one embodiment of the present invention, Figure 3 and Figure 5As shown, the other end of the coating roller 34 is provided with a coating motor 31 for driving it to rotate, and the end of the coating roller 34 is provided with a support plate 32, which is used to support the end of the coating roller 34, and the support plate 32 is connected to the power shaft of the coating motor 31, and the air inlet end of the negative pressure fan 36 is provided with a back-suction hood 35, and the back-suction hood 35 and the coating roller 34 are rotatably connected by a rotating seat 351. An isolation baffle 33 is provided inside the coating roller 34, and the top of the isolation baffle 33 is fixedly connected to the back-suction hood 35 by a fixed shaft 331, so that the isolation baffle 33 is fixed and does not rotate, and the isolation baffle 33 is an inverted V-shaped structure, and the opening of the isolation baffle 33 is downward, and the front and rear ends of the isolation baffle 33 are provided with end plates 332, and the bottom edge portion of the end plate 332 is adapted to the inner wall of the coating roller 34, and the isolation baffle 33 is fixedly connected to the back-suction hood 35.

[0030] Specifically, after the glass fiber is adsorbed by negative pressure on the surface of the coating roller 34, the portion of the coating roller 34 located on the upper side of the isolation baffle 33 is connected to the negative pressure fan 36 through the back-suction hood 35. The coating roller 34 on the upper side of the isolation baffle 33 has negative pressure suction, which on the one hand allows the segmented glass fiber to be adsorbed on this portion, and on the other hand, glass fiber debris will enter the interior of the mesh coating roller 34 and be absorbed and transferred by the negative pressure fan 36 to prevent glass fiber debris from splashing.

[0031] Since the lower part of the isolation baffle 33 is isolated from the back-suction hood 35, the coating roller 34 on the lower side of the isolation baffle 33 does not have negative pressure suction. When the glass fibers on the coating roller 34 rotate to the lower side of the isolation baffle 33, the glass fibers are not attracted and are more likely to fall onto the surface of the plate.

[0032] In one embodiment of the present invention, Figure 3 and Figure 5 As shown, an inner mask 27 is provided on the outer side of the coating roller 34, and the inner mask 27 is used to mask the glass fiber debris on the coating roller 34. A pressing roller 281 is provided between the inner mask 27 and the coating roller 34, and the pressing roller 281 corresponds to the isolation baffle 33. A material leveling roller 28 is provided on the coating roller 34. A scraper roller 282 is provided on the side of the coating roller 34 away from the coating roller 45, and a scraper brush is provided on the surface of the scraper roller 282, and the scraper brush is in contact with the coating surface of the coating roller 34.

[0033] Specifically, after the distribution tube 23 discharges the glass fibers onto the coating roller 34, the glass fibers on the coating roller 34 are first evenly dispersed on the coating roller 34 through the material leveling roller 28, and then enter the bottom of the isolation baffle 33, and are compressed by the compression roller 281, so that the glass fibers can be formed into thin sheets, so that the glass fibers can be more fully attached to the plate.

[0034] After the glass fiber is attached to the board, Figure 5 As shown, as the coating roller 34 continues to rotate, since the scraper roller 282 and the bottom of the coating roller 34 are in contact with the plate, the scraper roller 282 and the coating roller 34 rotate in the same direction, friction occurs between the scraper roller 282 and the coating roller 34, and the scraper brush on the scraper roller 282 cleans the glass fiber remaining on the coating roller 34, so that the surface of the coating roller 34 remains clean, preventing the glass fiber from clogging the surface of the coating roller 34.

[0035] In addition, since the scraper roller 282 is located on the upper side of the opening of the isolation baffle 33, the glass fibers swept by the scraper roller 282 continue to be adsorbed by the negative pressure suction on the coating roller 34, and the remaining glass fibers are subjected to the next round of coating.

[0036] In one embodiment of the present invention, Figure 3 As shown, a spiral support rib 341 is provided on the circumferential wall of the coating roller 34 to support the shape of the coating roller 34 so that the coating roller 34 is in firm contact with the surface of the plate.

[0037] In one embodiment of the present invention, Figure 2-Figure 7 As shown, the feeding end of the fabric pipe 23 is provided with a transmission pipe 22. The air outlet end of the negative pressure fan 36 is connected to the feeding end of the transmission pipe 22 through the exhaust pipe 361, the spiral edge of the fabric spiral shaft 232 is provided with a fabric brush, the fabric outlet 234 is a strip structure, and the fabric outlet 234 and the spiral blades of the fabric spiral shaft 232 are parallel to each other, and the end of the fabric pipe 23 away from the transmission pipe 22 is provided with a return pipe 26, and the return outlet 261 of the return pipe 26 is connected to the feeding end of the transmission pipe 22.

[0038] Specifically, the transmission tube 22 transmits the glass fiber to the inside of the distribution tube 23. After passing through the distribution spiral shaft 232 inside the distribution tube 23, the distribution brush on the edge of the distribution spiral shaft 232 sweeps the segmented glass fiber into each strip-shaped distribution outlet 234 in parallel, and the glass fiber is evenly discharged onto the coating roller 34 along the strip-shaped distribution outlet 234.

[0039] The remaining glass fibers in the distribution tube 23 enter the return tube 26 through the return air pump 263, and the return tube 26 sends the glass fibers back to the entrance of the distribution tube 23, so that the glass fibers are reused. The negative pressure fan 36 absorbs the glass fibers inside the coating roller 34 and retransmits them to the distribution tube 23 through the transmission tube 22, which greatly reduces the overflow of glass fibers.

[0040] In one embodiment of the present invention, Figure 3-Figure 5As shown, a throat 221 is provided in the middle of the transmission pipe 22, and the diameter of the middle part of the throat 221 is smaller than the diameter of the two sides. A return air pump 263 is provided at the return inlet 262 of the return pipe 26, and an air inlet 24 is provided at the feed end of the distribution pipe 23 corresponding to the return pipe 26, and an exhaust air pump 231 is provided at the feed end of the distribution pipe 23, and a distribution inlet 233 is provided at the feed end of the distribution pipe 23, and the distribution inlet 233 is communicated with the transmission pipe 22.

[0041] Specifically, the throat 221 in the middle of the transmission pipe 22 is a Laval nozzle structure, which plays a role in accelerating the glass fiber and the mixed air, so that the glass fiber is effectively projected into the inside of the distribution pipe 23. The glass fiber is sucked into the transmission pipe 22 through the exhaust air pump 231 and enters the distribution pipe 23, and the air mixed in the glass fiber is filtered out through the exhaust air pump 231. When the return air pump 263 recovers the glass fiber, air is added through the air inlet 24 set at the top of the distribution pipe 23, so that the glass fiber in the distribution pipe 23 can effectively flow out to the return pipe 26 for recycling.

[0042] In one embodiment of the present invention, Figure 2 and Figure 5 As shown, a coating motor 46 for driving a coating roller 45 to rotate is disposed on the outer mask 1, a coating seat 44 is disposed above the coating roller 45, a plurality of diversion hoses 441 are evenly disposed at the entrance end of the coating seat 44, a control valve 43 is disposed at the entrance end of the diversion hose 441, and a glue delivery pump 41 is disposed at the entrance end of the control valve 43.

[0043] Specifically, the adhesive is fed into the adhesive feeding pipe 42 through the adhesive feeding pump 41, the adhesive is released into the diversion hose 441 through the control valve 43, and is transmitted to the coating seat 44 through the diversion hose 441. When the coating motor 46 drives the coating roller 45 to rotate, the coating roller 45 absorbs the adhesive released from the coating seat 44 and transfers the adhesive to the plate along with the coating roller 45.

[0044] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, a cutting assembly 21 is provided at the feed end of the transmission tube 22, and the cutting assembly 21 includes a shearing seat 212, a feeding roller 213 and a cutting roller 214, wherein the shearing seat 212 is connected to the feed end of the transmission tube 22, the feeding roller 213 and the cutting roller 214 are arranged inside the shearing seat 212, the feeding roller 213 is arranged at the entrance end of the shearing seat 212, and the cutting roller 214 is arranged at the output end of the shearing seat 212, and both the feeding roller 213 and the cutting roller 214 are provided with two upper and lower ones.

[0045] Specifically, before the glass fibers are fed into the distribution tube 23, the bundled glass fibers will first be rolled by two feeding rollers 213 and gradually fed into the shear seat 212, and then the bundled glass fibers will be cut into segments by two cutting rollers 214. Then, the segmented glass fibers will be sucked into the transmission tube 22 by the action of airflow, and finally fed into the distribution tube 23.

[0046] In order to clearly explain the above embodiments, refer to Figure 1-8 The specific working principle of the chemical waste gas dust treatment device of the present invention is as follows: when spraying glass fiber on the surface of a plate-like plate, first place the equipment flat on the upper surface of the plate, and the adhesive is fed into the adhesive feeding pipe 42 through the adhesive feeding pump 41. The adhesive is released into the diverter hose 441 through the control valve 43, and is transmitted to the coating seat 44 through the diverter hose 441. The coating motor 46 drives the coating roller 45 to rotate, and the coating roller 45 absorbs the adhesive released from the coating seat 44 and transfers the adhesive to the plate along with the coating roller 45.

[0047] Then, the bundled glass fibers will first be fed into the feed roller 213 through the feed nozzle 211. The two feed rollers 213 feed the bundled glass fibers into the shear seat 212. Then, the bundled glass fibers will be cut into segments through two cutting rollers 214. The segmented glass fibers will be sucked into the transmission pipe 22 through the exhaust air pump 231 and finally fed into the cloth pipe 23. Then, the cloth motor 25 drives the cloth spiral shaft 232 to rotate. The cloth spiral shaft 232 will evenly transfer the glass fibers entering the cloth pipe 23 to the left. The cloth brush on the edge of the cloth spiral shaft 232 will sweep the segmented glass fibers into the strip-shaped cloth outlet 234 in parallel. The glass fibers are evenly discharged from each cloth outlet 234. Then, the glass fibers are discharged along the strip-shaped cloth outlet 234 to the coating roller 34.

[0048] In the above process, the remaining glass fibers in the distribution tube 23 enter the return pipe 26 through the return air pump 263, and the return pipe 26 re-transmits the glass fibers to the inlet of the distribution tube 23 for reuse. The negative pressure fan 36 absorbs the glass fibers inside the coating roller 34 and re-transmits them to the distribution tube 23 through the transmission tube 22 for reuse, thereby reducing the overflow of glass fibers.

[0049] Subsequently, the coating motor 31 drives the coating roller 34 to rotate. During the rotation of the coating roller 34, the portion of the coating roller 34 located on the upper side of the isolation baffle 33 is connected to the negative pressure fan 36 through the suction hood 35. The coating roller 34 on the upper side of the isolation baffle 33 has a negative pressure suction force, so that the segmented glass fiber is adsorbed on the surface of this portion of the coating roller 34, and the glass fiber debris will enter the interior of the mesh coating roller 34 and be absorbed and transferred by the negative pressure fan 36 to prevent the glass fiber debris from splashing.

[0050] When the glass fibers on the coating roller 34 rotate to the lower side of the isolation baffle 33, the glass fibers are not attracted and fall onto the surface of the plate. When the coating roller 34 rolls to contact the surface of the plate, the glass fibers on the coating roller 34 come into contact with the adhesive on the surface of the plate and are firmly attached to the surface of the plate. At the same time, the coating roller 34 can also compact the glass fibers coated on the plate, so that the glass fibers adhere more evenly and tightly, and are firmly coated on the surface of the plate.

[0051] In summary, the glass fiber spraying equipment of the embodiment of the present invention applies adhesive to the glass fiber attachment surface through the adhesive coating mechanism, and the glass fiber transmission mechanism evenly distributes the glass fibers, and then the distributed glass fibers are evenly spread on the surface of the coating roller. During the rotation of the coating roller, the negative pressure fan generates suction on the surface of the coating roller, which can make the glass fibers firmly adsorbed on the surface of the coating roller, and as the coating roller rotates, the glass fibers are finally pressed with the adhesive coated on the attachment surface, and the glass fibers are tightly spread on the attachment surface, which reduces the discharge of glass fiber debris and makes the glass fibers adhere more evenly and tightly.

[0052] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and deform the above embodiments within the scope of the present invention.
