[0002] Fireproof glass is a building material with special properties. It can provide effective protection in the event of a fire, slow the spread of fire, and protect the safety of people and property. In order to enhance its fireproof performance, it is usually necessary to spray a special fireproof coating on its fireproof side to form a heat-insulating protective layer under high temperature conditions, thereby effectively resisting high-temperature heating. When spraying fireproof glass, the existing fireproof glass spraying device usually places the glass on a spraying platform and adopts a single vertical spraying method. This method works better for flat glass, but faces challenges when processing curved glass. Due to the unique curved surface structure of curved glass, during the vertical spraying process, after the high-temperature resistant coating adheres to the curved surface, it is easy to flow under the action of gravity, resulting in difficulty in evenly distributing the coating, especially in areas with larger curvatures, thereby affecting the uniformity of the coating and the consistency of thickness.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] When spraying fire-resistant glass, the existing fire-resistant glass spraying device usually places the glass on a spraying platform and adopts a single vertical spraying method. However, when facing curved glass, due to its unique curved surface, during the vertical spraying process, the high-temperature resistant paint adheres to the curved surface and is easy to flow under the action of gravity. This geometric characteristic makes it difficult to evenly distribute the paint, especially in areas with larger curvatures, thereby affecting the uniformity and thickness consistency of the coating.

[0022] A spraying device for producing single-layer fireproof glass, such as Figure 1 and Figure 2As shown, it includes: a bracket 1; a fixed slide 2, fixedly connected to the bracket 1, and the fixed slide 2 is slidably connected to the electric slide 3; a support frame 4, slidably connected to the electric slide 3; a plurality of nozzles 5, all of which are arranged on the support frame 4; a first servo motor 6, fixedly connected to the bracket 1, and the output shaft of the first servo motor 6 is fixedly connected to a fixed frame 7, the fixed frame 7 is rotatably connected to the bracket 1, and a plurality of fixed components are arranged on the fixed frame 7, and the plurality of fixed components are used to adaptively fix glass of different curvatures, and a locking component for stabilizing the glass is arranged on the fixed frame 7; a first elastic element 8 is arranged between the electric slide 3 and the support frame 4, and the support frame 4 is rotatably connected to a positioning roller 9.

[0023] In the above scheme, a control terminal (not shown in the figure) is arranged on the bracket 1. The bracket 1 and the fixed slide 2 are both made of high-strength steel, have good stability and durability, and bear the dynamic load of the whole 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 the glass by the plurality of nozzles 5, and the plurality of fixed components are evenly spaced and distributed on the fixed frame 7. The fixed frame 7 is initially in a horizontal state, which is convenient for placing 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 the plurality of fixed components on the fixed frame 7. The glass is thinly sprayed by the nozzle 5 in a cycle, and the tangent of the glass spraying position is always in a horizontal state. The coating is vertically attached to the outside of the glass, which reduces the flow probability of the coating attached to the outside of the glass, improves the uniformity of the glass spraying, and improves the spraying quality of the glass.

[0024] 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 nozzle 5 and the glass remains unchanged, thereby improving the quality of glass spraying.

[0025] Specifically, Figure 3 As shown, the correction component includes: a correction shaft 10 slidably connected to the support frame 4; a pressure sensor 11 fixedly connected to the support frame 4, and a second elastic element 12 is arranged between the pressure sensor 11 and the correction shaft 10.

[0026] In the above scheme, the contact point between the correction shaft 10 and the glass plate is coplanar with the central axis of the injection port of several nozzles 5, the pressure sensor 11 is electrically connected to the control terminal, and the second elastic element 12 is a spring used to make the correction shaft 10 fit the glass, and the elastic coefficient of the second elastic element 12 is smaller than the elastic coefficient of the first elastic element 8.

[0027] Specifically, Figure 4 , Figure 6 and Figure 7 As shown, the fixed component includes: a plurality of elastic telescopic sleeves 201, all of which are fixedly connected to the fixed frame 7, the telescopic part of the elastic telescopic sleeve 201 is fixedly connected to the suction cup 202, the telescopic parts of the plurality of elastic telescopic sleeves 201 are commonly fixedly connected to the locking frame 203, and the telescopic parts of the plurality of elastic telescopic sleeves 201 are commonly provided with a blocking component for sealing themselves.

[0028] In the above scheme, the number of elastic telescopic sleeves 201 is freely set according to the width of the processed glass, the bottoms of the fixed parts of all elastic telescopic sleeves 201 are commonly 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 glass and can maintain good sealing on inclined surfaces or curved surfaces. Initially, the heights of the telescopic parts of all elastic telescopic sleeves 201 are in a flush state, and the fixed part and the telescopic part of the elastic telescopic sleeve 201 cooperate to autonomously adapt to the fixation of glass with different curvatures.

[0029] Specifically, Figure 5-Figure 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; a rack locking frame 206, having two, both slidably connected to the fixed frame 7, the two rack locking frames 206 are used to clamp and lock all the locking frames 203, and the two rack locking frames 206 are both engaged with the first gear 205.

[0030] In the above scheme, the materials of the first gear 205 and the rack locking frame 206 are both high-strength steel, which are used to bear the load of the clamping locking frame 203. The contact surface between the locking frame 203 and the two rack locking frames 206 is a rough surface, which is used to increase the friction between itself and the rack locking frame 206, and improve the tightness of the two rack locking frames 206 to the locking frame 203.

[0031] Specifically, Figure 6 and Figure 7 As shown, the blocking component includes: a blocking piston 301, which is the same in number as the elastic telescopic sleeve 201, a connecting frame is fixedly connected in the telescopic part of the elastic telescopic sleeve 201, the blocking piston 301 is slidably connected to the connecting frame in the telescopic part of the adjacent elastic telescopic sleeve 201, the blocking piston 301 is used to block the adjacent elastic telescopic sleeve 201, a third elastic element 302 is arranged between the connecting frame in the telescopic part of the elastic telescopic sleeve 201 and the adjacent blocking piston 301, and a driving component for driving the adjacent blocking piston 301 to move is arranged on the locking frame 203.

[0032] In the above solution, the blocking piston 301 is located in the telescopic part of the elastic telescopic sleeve 201, and 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.

[0033] Specifically, Figure 6 and Figure 7 As shown, the driving assembly includes: detection cylinders 303, which are the same in number as the blocking pistons 301 and are respectively fixedly connected to adjacent blocking pistons 301; the detection cylinder 303 is sealingly and slidably connected to the telescopic part of the adjacent elastic telescopic sleeve 201; the detection cylinder 303 is communicated with the telescopic part of the adjacent elastic telescopic sleeve 201; a sliding piston 304 is sealingly and slidably connected inside the detection cylinder 303; a fourth elastic element 305 is provided between the detection cylinder 303 and the sliding piston 304; the locking frame 203 is limitedly and slidably connected to the extrusion frame 306; the extrusion frame 306 is slidably connected to any rack locking frame 206; and the extrusion frame 306 is used to extrude the adjacent sliding piston 304.

[0034] In the above scheme, the detection cylinder 303 is connected to the telescopic part of the adjacent elastic telescopic sleeve 201 by sliding up and down. The detection cylinder 303 is composed of a cylinder body and a partition. The partition of the detection cylinder 303 is used to make the detection cylinder 303 slide up and down along the telescopic part of the elastic telescopic sleeve 201 while still maintaining the negative pressure state of the elastic telescopic sleeve 201. The fourth elastic element 305 is a spring, which is used to drive the adjacent sliding piston 304 to reset. Figure 6 The direction is explained as an example, all the extrusion frames 306 are slidably connected to the left rack locking frame 206, the extrusion frame 306 has the same number of inclined surfaces as the adjacent elastic telescopic sleeves 201 (when the number of elastic telescopic sleeves 201 in the fixed assembly is three, the number of inclined surfaces on the extrusion frame 306 is also three), and the direction of the inclined surface on the extrusion frame 306 is toward the lower right, and the elastic telescopic sleeves 201 that fail to be adsorbed are blocked to stabilize the adsorption strength of the remaining suction cups 202 on the glass.

[0035] When the curved glass needs to be sprayed, the staff will place the curved glass on all the suction cups 202, and the side that needs to be sprayed with the high temperature resistant paint faces upward. At this time, all the suction cups 202 are fitted to the shape of the curved glass. Here, the convex side of the curved glass is used as the side that needs to be sprayed. At this time, the telescopic part of the elastic telescopic sleeve 201 slides downward along its fixed part under the gravity of the glass, and the elastic telescopic sleeve 201 accumulates force until all the suction cups 202 are fitted to the outside of the glass and stabilized. Figure 1The state shown is then opened, and the external negative pressure extraction device is made to act on the glass through the elastic telescopic sleeve 201 and the suction cup 202, thereby adsorbing and fixing the glass. The telescopic portion of the evenly distributed elastic telescopic sleeve 201 is made to slide along its fixed portion to autonomously adapt to the glass of different curvatures, and the suction cup 202 is attached to the glass to adsorb and fix the glass, thereby adapting to the spraying operation of glass of different curvatures and improving the stability of the glass fixation.

[0036] When all the suction cups 202 have finished sucking the glass, the second servo motor 204 is turned on, and the output shaft of the second servo motor 204 drives the first gear 205 to rotate, and the first gear 205 drives the two rack locking frames 206 to move in opposite directions, so that the two rack locking frames 206 are in contact with all the locking frames 203 and squeeze each other, and the two rack locking frames 206 apply force to all the locking frames 203, and all the locking frames 203 are locked and fixed by friction, thereby improving the fixing degree of the suction cups 202 on all the elastic telescopic sleeves 201 to the glass. At this time, the glass is fixed.

[0037] In the above-mentioned process of fixing the curved glass, the suction cup 202 is very likely to age or wear due to long-term use, resulting in the suction cup 202 being unable to successfully adsorb the glass. Since several suction cups 202 and the elastic telescopic sleeve 201 share a negative pressure system, when a suction cup 202 fails to adsorb the glass, the negative pressure environment cannot be formed in the corresponding elastic telescopic sleeve 201 and connected to the external environment. The gas in the elastic telescopic sleeve 201 is always in a flowing state due to the extraction force, and the flowing gas can easily affect the adsorption strength of the remaining elastic telescopic sleeves 201 and suction cups 202 on the glass.

[0038] To solve the above problem, after the suction cup 202 successfully adsorbs the glass, the corresponding elastic telescopic sleeve 201 forms a negative pressure environment. At this time, the gas under the external normal pressure environment will push the sliding piston 304, and the adjacent fourth elastic element 305 will be compressed, until the sliding piston 304 slides to the limit state. At this time, the sliding piston 304 is separated from the adjacent extrusion frame 306, that is, the extrusion frame 306 cannot drive the blocking piston 301 to move 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 the adsorption directly acts on the glass. On the contrary, the suction cup 202 fails to adsorb the glass successfully, and the corresponding negative pressure environment cannot be formed in the 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 toward each other and lock the locking frame 203, the left rack locking frame 206 ( Figure 6The direction is explained as an example) will drive the extrusion frame 306 thereon to move synchronously, so that the extrusion frame 306 squeezes the sliding piston 304 in the original position. At this time, the sliding piston 304 is driven by the extrusion force to drive the blocking piston 301 to move downward through the detection tube 303. At the same time, the third elastic element 302 is compressed, so that the blocking piston 301 blocks the adjacent elastic telescopic sleeve 201, so that the elastic telescopic sleeve 201 that has not been successfully adsorbed also forms a closed environment, and thus no flowing airflow is formed, thereby improving the adsorption stability of the remaining suction cups 202 on the glass.

[0039] When the glass is fixed, the servo motor 6 is turned on, and the output shaft of the servo motor 6 drives the fixing frame 7 to deflect clockwise (by Figure 1 The direction is explained as an example), so that the fixed frame 7 drives the normal line of the leftmost part of the glass to be in a vertical state through all the elastic telescopic sleeves 201 thereon, and at the same time, the electric slide 3 is turned on, so that the electric slide 3 drives the plurality of nozzles 5 to move synchronously through the support frame 4 until the nozzle 5 moves to the upper leftmost part of the glass, and then the electric slide 3 synchronously drives the support frame 4 to start moving from the left side to the right side, and at the same time, the plurality of nozzles 5 are turned on, and the plurality of nozzles 5 begin to spray thinly on the left side of the glass, and at the same time, the output shaft of the servo motor 6 starts to drive the fixed frame 7 to rotate counterclockwise to spray the glass The tangent of the position is always in a horizontal state, even if the paint is vertically attached to the outside of the glass, until the nozzle 5 moves to the upper rightmost part of the glass, and then the output shaft of the servo motor 6 rotates in the opposite direction, and at the same time the electric slide 3 drives several nozzles 5 to move in the opposite direction through the support frame 4, and this cycle is repeated until the glass is sprayed. The glass is thinly sprayed through the cycle, and the tangent of the glass spraying position is always in a horizontal state, even if the paint is vertically attached to the outside of the glass, reducing the flow probability of the paint adhering to the outside of the glass, improving the uniformity of the glass spraying, and improving the spraying quality of the glass.

[0040] When placing the glass, the glass will squeeze the positioning roller 9, so that the positioning roller 9 is always located at the lower side of the glass and in contact with each other, and the positioning roller 9 drives the support frame 4 to slide downward synchronously along the electric slide 3, and the first elastic element 8 is compressed. Later, when the electric slide 3 drives the nozzle 5 to spray the glass from left to right through 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 synchronously in a deflection process, causing the height of the glass spraying position to change, and the positioning roller 9 is always in contact with the lower side of the glass under the action of the first elastic element 8, that is, 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 changes the height of several nozzles 5 synchronously through the support frame 4, so that the distance between the nozzle 5 and the glass remains unchanged, thereby improving the quality of glass spraying.

[0041] When placing the glass, the glass will squeeze 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 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 at a constant value, and the compression degree of the second elastic element 12 is at a constant value, the sensing value of the pressure sensor 11 is at a constant value. When the electric slide 3 and the servo motor 6 are aged or there is an error in the parameter setting of the two, the running speed of the electric slide 3 and the rotation speed of the output shaft of the servo motor 6 are The degree of mismatch 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 of 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 controls the electric slide 3 to slow down or accelerate the electric slide 3, thereby correcting the spraying positions of several nozzles 5, so that the actual spraying positions of several nozzles 5 on the glass coincide with the set spraying positions, thereby ensuring the uniformity of glass spraying, and this continues until the glass spraying is completed.

[0042] When the glass spraying is completed, the servo motor 6 is turned on, so that the output shaft of the servo motor 6 drives the glass to return to the initial state through the several elastic telescopic sleeves 201 on the fixed frame 7, that is, the servo motor 6 is turned off after the fixed frame 7 is in the horizontal state, and the electric slide 3 drives the support frame 4 to reset to the initial state, and then the second servo motor 204 is turned on, so that the output shaft of the second servo motor 204 drives the two rack locking frames 206 to reset to the initial state through the first gear 205, and the clamping force on all locking frames 203 is released. The third elastic element 302 in the compressed state drives the adjacent blocking pistons 301 to reset and releases the blocking of the adjacent elastic telescopic sleeves 201, and then the external negative pressure extraction device is closed. At this time, each elastic telescopic sleeve 201 returns to the normal pressure state, and at the same time, the fourth elastic element 305 in the compressed state drives the sliding piston 304 to reset, and then the glass after spraying is removed. At this time, the telescopic part of the elastic telescopic sleeve 201 is reset to the initial flush state, and when the curved glass needs to be sprayed again, the above steps are repeated.

[0043] In a further embodiment, Figure 8 and Fig. 9 As shown, it also includes: an adjustment component, which is arranged 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 all slidably connected to the support frame 4. The telescopic part of the electric push rod 401 is fixedly connected to any nozzle 5 in the sliding connection with the support frame 4, and all the nozzles 5 are commonly installed with a telescopic frame 402.

[0044] In the above scheme, the number of nozzles 5 is illustrated as five as an example, and Figure 8 The direction is explained, wherein the nozzle 5 located in the middle is fixedly connected to the support frame 4, 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 nozzle 5 on the far left, and the five rotating pins in the middle of the telescopic frame 402 are respectively fixedly connected to the five nozzles 5. By pushing the leftmost nozzle 5 to move, the distance between two adjacent nozzles 5 is changed, and then the overall arrangement length of the nozzles 5 is changed, so as to spray glass of different widths.

[0045] Specifically, Figure 8 and Fig. 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 with the second gear 403, the nozzle 5 is slidably connected with the spur rack 404, the second gear 403 is meshed with the spur rack 404, and the support frame 4 is provided with a pushing component for driving all the spur racks 404 to move.

[0046] In the above scheme, Figure 8 The direction shown is explained, the nozzle 5 is an adjustable nozzle, and the spraying range of the nozzle 5 can be changed. The adjusting end of the nozzle 5 rotates clockwise to increase the spraying range of the nozzle 5, and rotates counterclockwise to reduce the spraying range of the nozzle 5. The spur rack 404 moves up and down to drive the adjacent second gear 403 to rotate, so that the second gear 403 drives the adjusting end of the nozzle 5 to rotate to change its own spraying range.

[0047] Specifically, Figure 8 and Fig. 9 As shown, the pushing assembly includes: a pulling rod 405, which is slidably connected to the supporting frame 4, and all the spur rack frames 404 are slidably connected to the pulling rod 405; an extrusion plate 406, which is fixedly connected to the telescopic part of the electric push rod 401, and the extrusion plate 406 is provided with a slide groove 407, and the pulling rod 405 is located in the slide groove 407.

[0048] In the above scheme, the slide groove 407 is arranged at an angle, and the telescopic part of the electric push rod 401 causes the extrusion plate 406 to move synchronously when changing the position of the nozzle 5. The extrusion plate 406 drives the pulling rod 405 to slide up and down by sliding along the inclined slide groove 407, thereby synchronously adjusting the spraying range of all nozzles 5, ensuring that the high temperature resistant paint is evenly sprayed on the outside of the glass and reducing resource waste.

[0049] When spraying high temperature resistant coating on curved glass, there are models of curved glass with different widths. After changing the model of curved glass, the spraying width changes. When the spraying width increases, it is difficult for the nozzle 5 to fully cover the glass, resulting in a spraying dead angle at the edge of the curved glass. When the spraying width decreases, the coverage area of ​​the nozzle 5 is larger than the glass, resulting in a large amount of high temperature resistant coating being sprayed to the outside, wasting a large amount of high temperature resistant coating. Therefore, when the width of the glass changes, the increase in the width of the glass is taken as an example, and Figure 8 The direction shown is explained, the electric push rod 401 is turned on, and the telescopic part of the electric push rod 401 drives the leftmost nozzle 5 to slide to the left along the support frame 4, and the leftmost nozzle 5 drives the telescopic frame 402 to gradually lengthen, and the middle nozzle 5 is taken as a reference, so that the telescopic frame 402 drives the nozzles 5 on both sides of the middle nozzle 5 to move backwards, and due to the characteristics of the telescopic frame 402, a number of nozzles 5 are always in an equidistant change during this process, and the overall arrangement length of a number of nozzles 5 is extended to adapt to the width of the glass, until the overall arrangement length of a number of nozzles 5 reaches the required length, and then the electric push rod 401 is turned off, and the pulling of the nozzle 5 is stopped.

[0050] After the overall arrangement length of the plurality of nozzles 5 is extended, the spraying area responsible for a single nozzle 5 is synchronously increased, so when the telescopic portion of the electric push rod 401 drives the leftmost nozzle 5 to slide to the left along the support frame 4, the telescopic portion of the electric push rod 401 drives the extrusion plate 406 to move synchronously, and the extrusion plate 406 drives the upper slide groove 407 to move synchronously, so that the slide groove 407 squeezes the pulling rod 405, and the pulling rod 405 slides downward along the support frame 4 under the extrusion force, and the pulling rod 405 pulls the plurality of spur racks 404 to move downward synchronously, and the downward movement of the spur rack 404 drives the adjacent second gear 403 to rotate clockwise, and drives the adjusting end of the nozzle 5 to rotate clockwise synchronously, thereby increasing the spraying range of the nozzle 5, so that the high-temperature resistant paint sprayed by the plurality of nozzles 5 is evenly sprayed onto the glass, thereby improving the uniformity of the glass spraying, and when the glass needs to be replaced again, the above steps are repeated according to the glass spraying width.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
