Description

Technical Field

[0001] This invention relates to the field of glass fireproof coating technology, and more particularly to a spraying device for producing single-layer fireproof glass. Background Technology

[0002] Fire-resistant glass is a building material with special properties that can provide effective protection during a fire, delaying the spread of fire and protecting people and property. To enhance its fire resistance, a special fire-resistant coating is usually applied to its fire-resistant side to form a heat-insulating protective layer under high-temperature conditions, thereby effectively resisting high-temperature heating. Existing fire-resistant glass spraying equipment typically places the glass on a spraying platform and uses a single vertical spraying method. This method works well for flat glass, but it faces challenges when dealing with curved glass. Due to the unique curved surface structure of curved glass, the high-temperature resistant coating tends to flow under gravity after adhering to the curved surface during vertical spraying, making it difficult for the coating to be evenly distributed, especially in areas with greater curvature, thus affecting the uniformity and thickness consistency of the coating.

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0046] Existing fire-resistant glass spraying equipment typically places the glass on a spraying platform and uses a single vertical spraying method when spraying fire-resistant glass. However, when dealing with curved glass, due to its unique curved surface, the high-temperature resistant coating tends to flow under gravity after adhering to the curved surface during vertical spraying. This geometric characteristic makes it difficult for the coating to be evenly distributed, especially in areas with large curvature, thus affecting the uniformity and thickness consistency of the coating.

[0047] A spraying device for producing single-layer fireproof glass, such as Figure 1 and Figure 2 As shown, it includes: a bracket 1; a fixed carriage 2, fixedly connected to the bracket 1, with an electric carriage 3 slidably connected to the fixed carriage 2; a support frame 4, slidably connected to the electric carriage 3; several nozzles 5, all mounted on the support frame 4; a first servo motor 6, fixedly connected to the bracket 1, with its output shaft fixedly connected to a fixed frame 7, the fixed frame 7 rotatably connected to the bracket 1, the fixed frame 7 having several fixing components for adaptively fixing glass of different curvatures, and the fixed frame 7 having locking components for stabilizing the glass; a first elastic element 8 between the electric carriage 3 and the support frame 4, and a positioning roller 9 rotatably connected to the support frame 4.

[0048] In the above scheme, a control terminal (not shown in the figure) is set on the bracket 1. Both the bracket 1 and the fixed slide 2 are made of high-strength steel, which has good stability and durability and can bear the dynamic load of the entire device. The electric slide 3 is electrically connected to the control terminal. The electric slide 3 slides laterally along the fixed slide 2 to change the spraying position of several nozzles 5 on the glass. Several fixed components are evenly distributed on the fixed frame 7. The fixed frame 7 is initially in a horizontal state to facilitate the placement of the glass. The first servo motor 6 is electrically connected to the control terminal. The first servo motor 6 can drive the fixed glass to rotate through several fixed components on the fixed frame 7. By making the nozzles 5 cyclically spray the glass in a thin layer, and keeping the tangent of the glass spraying position in a horizontal state, the paint is vertically attached to the outside of the glass, reducing the probability of paint flowing on the outside of the glass, improving the uniformity of glass spraying, and improving the spraying quality of the glass.

[0049] The first elastic element 8 is a spring. After the glass plate is fixed, the first elastic element 8 is in a compressed state to ensure that the positioning roller 9 is always in contact with the lower side of the glass. The positioning roller 9 changes the height of several nozzles 5 synchronously through the support frame 4. The distance between the nozzles 5 and the glass remains unchanged, thereby improving the quality of glass spraying.

[0050] Specifically, such as Figure 3 As shown, the correction assembly includes: a correction shaft 10, which is slidably connected to the support frame 4; a pressure sensor 11, which is fixedly connected to the support frame 4; and a second elastic element 12 is provided between the pressure sensor 11 and the correction shaft 10.

[0051] In the above scheme, the contact point between the correction shaft 10 and the glass plate is coplanar with the central axis of the spray nozzles of several nozzles 5. The pressure sensor 11 is electrically connected to the control terminal. The second elastic element 12 is a spring used to make the correction shaft 10 fit against the glass. The elastic coefficient of the second elastic element 12 is less than the elastic coefficient of the first elastic element 8.

[0052] Specifically, such as Figure 4 , Figure 6 and Figure 7 As shown, the fixing component includes: several elastic telescopic sleeves 201, all of which are fixedly connected to the fixing frame 7. The telescopic part of the elastic telescopic sleeve 201 is fixedly connected to a suction cup 202. The telescopic parts of several elastic telescopic sleeves 201 are jointly fixedly connected to a locking frame 203. The telescopic parts of several elastic telescopic sleeves 201 are jointly provided with a sealing component for sealing themselves.

[0053] In the above scheme, the number of elastic telescopic sleeves 201 is freely set according to the width of the processed glass. The bottom of the fixed part of all elastic telescopic sleeves 201 is connected to the external negative pressure extraction device. The suction cup 202 is made of silicone, which has good deformation ability and is used to improve the sealing strength between the sleeve and the glass. It can maintain good sealing performance on inclined or curved surfaces. Initially, the height of the telescopic parts of all elastic telescopic sleeves 201 is at the same level. The fixed part and telescopic part of the elastic telescopic sleeve 201 cooperate to adapt to the fixing of glass with different curvatures.

[0054] Specifically, such as Figures 5-7 As shown, the locking assembly includes: a second servo motor 204, fixedly connected to the fixed frame 7; a first gear 205, fixedly connected to the output shaft of the second servo motor 204; and two rack locking brackets 206, both of which are slidably connected to the fixed frame 7. The two rack locking brackets 206 are used to lock all locking brackets 203, and both rack locking brackets 206 mesh with the first gear 205.

[0055] In the above scheme, the first gear 205 and the rack locking bracket 206 are both made of high-strength steel to bear the load of the clamping locking bracket 203. The contact surface between the locking bracket 203 and the two rack locking brackets 206 is a rough surface to increase the friction between itself and the rack locking brackets 206 and improve the tightness of the two rack locking brackets 206 on the locking bracket 203.

[0056] Specifically, such as Figure 6 and Figure 7 As shown, the sealing assembly includes: sealing pistons 301, the same number as the elastic telescopic sleeves 201; a connecting frame is fixedly connected inside the telescopic part of the elastic telescopic sleeve 201; the sealing pistons 301 are slidably connected to the connecting frames inside the telescopic parts of adjacent elastic telescopic sleeves 201; the sealing pistons 301 are used to seal adjacent elastic telescopic sleeves 201; a third elastic element 302 is provided between the connecting frame inside the telescopic part of the elastic telescopic sleeve 201 and the adjacent sealing pistons 301; and a driving assembly for driving the adjacent sealing pistons 301 to move is provided on the locking frame 203.

[0057] In the above scheme, the blocking piston 301 is located inside the telescopic part of the elastic telescopic sleeve 201. The blocking piston 301 can move synchronously with the telescopic part. The third elastic element 302 is a tension spring, which is used to drive the adjacent blocking piston 301 to reset.

[0058] Specifically, such as Figure 6 and Figure 7As shown, the drive assembly includes: a detection cylinder 303, the same number as the blocking piston 301, which is fixedly connected to the adjacent blocking piston 301. The detection cylinder 303 is slidably connected to the telescopic part of the adjacent elastic telescopic sleeve 201 and communicates with the telescopic part of the adjacent elastic telescopic sleeve 201. A sliding piston 304 is slidably connected inside the detection cylinder 303. A fourth elastic element 305 is provided between the detection cylinder 303 and the sliding piston 304. A compression frame 306 is slidably connected to the locking frame 203 and is slidably connected to it. The compression frame 306 is slidably connected to any rack locking frame 206 and is used to compress the adjacent sliding piston 304.

[0059] In the above scheme, the detection cylinder 303 is slidably connected vertically to the telescopic part of the adjacent elastic telescopic sleeve 201. The detection cylinder 303 consists of a cylinder body and a partition. The partition of the detection cylinder 303 is used to maintain the negative pressure state of the elastic telescopic sleeve 201 when the detection cylinder 303 slides vertically along the telescopic part of the elastic telescopic sleeve 201. The fourth elastic element 305 is a spring, used to drive the adjacent sliding piston 304 to reset. Figure 6 To illustrate the direction, all the extrusion frames 306 are slidably connected to the left rack and pinion clamping frame 206. The extrusion frame 306 has the same number of inclined surfaces as the adjacent elastic telescopic sleeves 201 (when there are three elastic telescopic sleeves 201 in the fixing assembly, there are also three inclined surfaces on the extrusion frame 306), and the inclined surfaces on the extrusion frame 306 face downward to the right. By blocking the elastic telescopic sleeves 201 that fail to adhere, the adhesion strength of the remaining suction cups 202 to the glass is stabilized.

[0060] When spraying curved glass, the operator places the curved glass onto all the suction cups 202, with the side to be sprayed with the high-temperature resistant coating facing upwards. At this point, all the suction cups 202 conform to the shape of the curved glass. Here, we will describe the side of the curved glass that needs to be sprayed as the convex side. The telescopic part of the elastic telescopic sleeve 201 slides downwards along its fixed part under the force of the glass's gravity, storing force. This continues until all the suction cups 202 are adhered to the outside of the glass and stabilized. Figure 1 As shown in the diagram, the external negative pressure extraction device is then activated, allowing the negative pressure extraction force to act on the glass through the elastic telescopic sleeve 201 and the suction cup 202, thereby adsorbing and fixing the glass. By allowing the telescopic part of the evenly distributed elastic telescopic sleeve 201 to slide along its fixed part, it can autonomously adapt to glass with different curvatures, and the suction cup 202 is attached to the glass to adsorb and fix the glass, thus adapting to glass spraying operations with different curvatures and improving the stability of glass fixation.

[0061] Once all the suction cups 202 have adsorbed the glass, the second servo motor 204 is activated. The output shaft of the second servo motor 204 drives the first gear 205 to rotate. The first gear 205 drives the two rack locking brackets 206 to move in opposite directions, so that the two rack locking brackets 206 contact all the locking brackets 203 and press against each other. The two rack locking brackets 206 apply force to all the locking brackets 203, locking all the locking brackets 203 through friction, thereby improving the stability of the glass fixation by the suction cups 202 on all the elastic telescopic sleeves 201. At this point, the glass fixation is complete.

[0062] During the aforementioned process of fixing curved glass, the suction cup 202 is prone to aging or wear due to prolonged use, which may cause it to fail to successfully adsorb the glass. Since several suction cups 202 and elastic telescopic sleeves 201 share a negative pressure system, when one suction cup 202 fails to adsorb the glass, the corresponding elastic telescopic sleeve 201 cannot form a negative pressure environment and connect with the external environment. The gas inside the elastic telescopic sleeve 201 is constantly in a state of flow due to the suction force, and the flowing gas can easily affect the adsorption strength of the other elastic telescopic sleeves 201 and suction cups 202 on the glass.

[0063] To solve the above problems, when the suction cup 202 successfully adsorbs the glass, the corresponding elastic telescopic sleeve 201 forms a negative pressure environment. At this time, the gas in the external normal pressure environment will push the sliding piston 304, and at the same time, the adjacent fourth elastic element 305 is compressed. This continues until the sliding piston 304 slides to its limit. At this time, the sliding piston 304 separates from the adjacent extrusion frame 306. That is, the extrusion frame 306 cannot drive the sealing piston 301 downward through the sliding piston 304 and the detection cylinder 303, so that the negative pressure extraction force in the elastic telescopic sleeve 201 that has completed adsorption directly acts on the glass. Conversely, if the suction cup 202 fails to adsorb the glass, a negative pressure environment cannot be formed in the corresponding elastic telescopic sleeve 201, and the adjacent sliding piston 304 cannot slide along the adjacent detection cylinder 303. When the two rack locking frames 206 move in opposite directions to lock the locking frame 203, the left rack locking frame 206 ( Figure 6 (The direction is illustrated by example) It will drive the squeezing frame 306 to move synchronously, so that the squeezing frame 306 squeezes the sliding piston 304 in place. At this time, the sliding piston 304 is squeezed by the squeezing force and drives the sealing piston 301 to move downward through the detection cylinder 303. At the same time, the third elastic element 302 is compressed, so that the sealing piston 301 seals the adjacent elastic telescopic sleeve 201, so that the elastic telescopic sleeve 201 that has not been successfully adsorbed also forms a sealed environment, thereby preventing the formation of airflow and improving the adsorption stability of the other suction cups 202 on the glass.

[0064] Once the glass is fixed, servo motor 6 is activated. The output shaft of servo motor 6 drives the fixing frame 7 to rotate clockwise (to...). Figure 1(Using the direction as an example), the fixed frame 7, through all its elastic telescopic sleeves 201, causes the normal at the leftmost point of the glass to be in a vertical state. Simultaneously, the electric slide 3 is activated, causing the electric slide 3 to drive several nozzles 5 to move synchronously through the support frame 4 until the nozzles 5 move to the top left of the glass. Then, the electric slide 3 synchronously drives the support frame 4 to move from left to right, simultaneously activating several nozzles 5, which begin to perform a thin spray on the left side of the glass. At the same time, the output shaft of the servo motor 6 begins to drive the fixed frame 7 to rotate counterclockwise, causing the glass to be sprayed. The tangent at the spray position remains horizontal, even if the paint adheres vertically to the outside of the glass. This continues until the nozzle 5 moves to the upper right side of the glass. Then, the output shaft of the servo motor 6 rotates in the opposite direction, and the electric carriage 3 drives several nozzles 5 to move in the opposite direction through the support frame 4. This cycle continues until the glass is coated. By cyclically spraying the glass with a thin layer and keeping the tangent at the spray position horizontal, even if the paint adheres vertically to the outside of the glass, the probability of paint flowing on the outside of the glass is reduced, the uniformity of the glass coating is improved, and the quality of the glass coating is enhanced.

[0065] When the glass is placed, it presses against the positioning roller 9, ensuring that the positioning roller 9 remains on the lower side of the glass and in close contact with it. The positioning roller 9 drives the support frame 4 to slide synchronously downwards along the electric slide 3, while the first elastic element 8 is compressed. Subsequently, when the electric slide 3 drives the nozzles 5 to spray the glass from left to right via the support frame 4, the support frame 4 drives the positioning roller 9 to move synchronously. During the movement of the positioning roller 9, the glass is simultaneously deflected, causing the height of the glass spraying position to change. Under the action of the first elastic element 8, the positioning roller 9 remains in contact with the lower side of the glass, meaning that the height of the positioning roller 9 changes synchronously under the action of the first elastic element 8. At this time, the positioning roller 9 synchronously changes the height of several nozzles 5 via the support frame 4, keeping the distance between the nozzles 5 and the glass constant, thus improving the quality of glass spraying.

[0066] When placing the glass, the glass will press against the correction shaft 10, causing the correction shaft 10 to slide along the support frame 4. At the same time, the second elastic element 12 is compressed, and the pressure sensor 11 senses the pressure change. This continues until the glass is placed and fixed. Since the positioning roller 9 is in contact with the glass, the sliding distance of the correction shaft 10 along the support frame 4 is constant. Similarly, the degree of compression of the second elastic element 12 is constant, and the sensing value of the pressure sensor 11 is constant. When the electric carriage 3 and the servo motor 6 show signs of aging or when there are errors in their parameter settings, the running speed of the electric carriage 3 and the rotation speed of the output shaft of the servo motor 6 will be affected. The mismatch in spraying position causes the actual spraying position of several nozzles 5 on the glass to be misaligned with the set spraying position. At this time, the positioning roller 9 is not below the set spraying position on the glass, and the correction shaft 10 rises. At this time, the compression degree of the second elastic element 12 changes, the pressure sensor 11 senses the pressure change and sends a signal to the control terminal, so that the control terminal operates the electric slide 3 to decelerate or accelerate, thereby correcting the spraying position of several nozzles 5, so that the actual spraying position of several nozzles 5 on the glass coincides with the set spraying position, ensuring the uniformity of glass spraying. This continues until the glass spraying is completed.

[0067] After the glass is coated, the servo motor 6 is turned on, causing its output shaft to drive the glass back to its initial state via several elastic telescopic sleeves 201 on the fixed frame 7. Once the fixed frame 7 is in a horizontal state, the servo motor 6 is turned off. At the same time, the electric slide 3 drives the support frame 4 to reset to its initial state. Then, the second servo motor 204 is turned on, causing its output shaft to drive two rack-and-pinion locking frames 206 back to their initial state via the first gear 205. This releases the clamping force on all locking frames 203. The compressed third elastic element 302 drives the adjacent sealing piston 301 to reset and releases the sealing of the adjacent elastic telescopic sleeves 201. Then, the external negative pressure extraction device is turned off, and each elastic telescopic sleeve 201 returns to normal pressure. At the same time, the compressed fourth elastic element 305 drives the sliding piston 304 to reset. The coated glass is then removed, and the telescopic parts of the elastic telescopic sleeves 201 return to their initial flush state. When it is necessary to coat curved glass again, the above steps are repeated.

[0068] In a further embodiment, such as Figure 8 and Figure 9 As shown, it also includes: an adjustment component, which is set on the support frame 4 and is used to adjust the spraying range of several nozzles 5. The adjustment component includes: an electric push rod 401, which is fixedly connected to the support frame 4. Any nozzle 5 is fixedly connected to the support frame 4, and the remaining nozzles 5 are slidably connected to the support frame 4. The telescopic part of the electric push rod 401 is slidably connected to any nozzle 5 and fixedly connected to the support frame 4. All nozzles 5 are mounted on a telescopic frame 402.

[0069] In the above scheme, the number of nozzles 5 is illustrated using the example of five nozzles shown in the diagram, and is further explained using... Figure 8 The following description is provided, showing that the nozzle 5 in the middle is fixedly connected to the support frame 4, and the four nozzles 5 on both sides are slidably connected to the support frame 4. The telescopic part of the electric push rod 401 is fixedly connected to the leftmost nozzle 5. The five rotating pins in the middle of the telescopic frame 402 are fixedly connected to the five nozzles 5 respectively. By pushing the leftmost nozzle 5 to move, the distance between two adjacent nozzles 5 is changed, thereby changing the overall arrangement length of several nozzles 5, so as to spray glass of different widths.

[0070] Specifically, such as Figure 8 and Figure 9 As shown, the nozzle 5 is provided with an adjustment end for adjusting its own spraying range. The adjustment end of the nozzle 5 is fixedly connected to a second gear 403. The nozzle 5 is slidably connected to a rack frame 404. The second gear 403 meshes with the rack frame 404. The support frame 4 is provided with a push component for driving all rack frames 404 to move.

[0071] In the above scheme, with Figure 8 The direction shown is explained. The nozzle 5 is an adjustable nozzle, which can change the spraying range of the nozzle 5. The spraying range of the nozzle 5 is increased by rotating the adjustment end of the nozzle 5 clockwise and decreased by rotating it counterclockwise. The vertical movement of the rack and pinion 404 drives the adjacent second gear 403 to rotate, so that the second gear 403 drives the adjustment end of the nozzle 5 to rotate and change its own spraying range.

[0072] Specifically, such as Figure 8 and Figure 9 As shown, the pushing assembly includes: a pull rod 405, which is slidably connected to the support frame 4, and all the rack frames 404 are slidably connected to the pull rod 405; and a pressing plate 406, which is fixedly connected to the telescopic part of the electric push rod 401, and the pressing plate 406 is provided with a groove 407, in which the pull rod 405 is located.

[0073] In the above scheme, the slide 407 is inclined. When the telescopic part of the electric push rod 401 changes the position of the nozzle 5, it causes the extrusion plate 406 to move synchronously. The extrusion plate 406 drives the pull rod 405 to slide up and down by sliding along the inclined slide 407, thereby synchronously adjusting the spray range of all nozzles 5, ensuring that the high-temperature resistant coating is evenly sprayed on the outside of the glass, and reducing resource waste.

[0074] When spraying high-temperature resistant coatings onto curved glass, different widths of curved glass are available. Changing the glass type alters the spray width. When the spray width increases, nozzle 5 struggles to fully cover the glass, resulting in spray dead zones at the edges. Conversely, when the spray width decreases, nozzle 5 covers an area larger than the glass, causing a significant amount of high-temperature resistant coating to be sprayed onto the exterior, wasting a large amount of the coating. Therefore, when the glass width changes (taking an increased width as an example), the spray width becomes crucial. Figure 8 The following describes the process: Activate the electric push rod 401. The telescopic part of the electric push rod 401 drives the leftmost nozzle 5 to slide to the left along the support frame 4. The leftmost nozzle 5 drives the telescopic frame 402 to gradually lengthen. Using the middle nozzle 5 as a reference, the telescopic frame 402 drives the nozzles 5 on both sides of the middle nozzle 5 to move in opposite directions. Due to the characteristics of the telescopic frame 402, the nozzles 5 remain at equal intervals throughout this process, extending the overall length of the nozzles 5 to adapt to the width of the glass. This continues until the overall length of the nozzles 5 reaches the required length. Then, the electric push rod 401 is closed, and the nozzles 5 are no longer pulled.

[0075] As the overall length of the nozzles 5 is extended, the spraying area of ​​each nozzle 5 increases synchronously. Therefore, when the telescopic part of the electric push rod 401 drives the leftmost nozzle 5 to slide to the left along the support frame 4, the telescopic part of the electric push rod 401 drives the extrusion plate 406 to move synchronously. The extrusion plate 406 drives the sliding groove 407 on it to move synchronously, causing the sliding groove 407 to press the pulling rod 405. The pulling rod 405 slides downward along the support frame 4 under the extrusion force. The pulling rod 405 pulls several rack frames 404 to move downward synchronously. The downward movement of the rack frames 404 drives the adjacent second gear 403 to rotate clockwise, which drives the adjusting end of the nozzle 5 to rotate clockwise synchronously, increasing the spraying range of the nozzle 5. This allows the high-temperature resistant coating sprayed by several nozzles 5 to be evenly sprayed onto the glass, improving the uniformity of the glass spraying. When the glass needs to be replaced again, the above steps are repeated according to the glass spraying width.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
