Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, and in particular to a fireproof coating machine and production process for fireproof glass production. Background Technology

[0002] In the production of fire-resistant glass, traditional coating machines often face challenges such as uneven coating thickness and poor adaptability to irregularly shaped glass. Conventional coating rollers have high rigidity and fixed scraper angles, making it difficult to follow the contours of curved or irregularly shaped glass, easily leading to uneven coating thickness, edge buildup, or missed areas, affecting fire resistance and appearance. To address this problem, existing technologies lack flexible coating solutions that can actively adapt to glass morphology, and there is an urgent need for an adaptively adjustable coating mechanism to achieve high-quality, uniform coating of glass with different shapes.

[0003] Patent publication number CN212018393U discloses a coating apparatus for vacuum glass processing, including a frame and a gantry. Multiple material rollers are rotatably connected to the inner sides of the frame via multiple pairs of rotating shafts. The material rollers are arranged laterally, and the rollers are evenly distributed longitudinally. The gantry is vertically fixed to the outer sides of the frame, and an adjustment component is vertically engaged at the top of the gantry. A marker is provided on one side of the adjustment component. This patent allows adjustment of the distance between the bottom edge of the scraper and the highest point of the material tube by rotating the stud. The protrusion and marker provide accurate reference for the number of rotations of the stud, enabling accurate and rapid adjustment of the coating thickness by advancing one thread pitch axially with each rotation of the stud's thread. This facilitates the selection of different thicknesses of protective coating based on the thickness of the vacuum glass, expanding the versatility of the coating apparatus.

[0004] Existing technologies suffer from the following drawbacks: poor adaptability to irregularly shaped glass: Existing coating devices often use rigid coating rollers and scrapers, which cannot conform to curved surfaces and angular contours, resulting in uneven paint transfer gaps. Furthermore, the coating pressure cannot be dynamically adjusted according to the curvature of the surface; excessive pressure at protruding areas causes paint buildup, while insufficient pressure at recessed areas leads to missed areas, excessively thin coatings, or even breakage. These problems directly compromise the continuity and uniformity of the coating, weakening the core heat insulation and flame-retardant properties of fire-resistant glass.

[0005] The inability to synchronously adjust the spacing between the coating roller and scraper and the glass: Existing coating devices use a fixed connection and lack independent servo control. This means that when dealing with irregular curved surfaces, the coating roller and scraper cannot coordinately adjust their spacing according to changes in the glass contour. This directly manifests as misalignment of their gaps, uncontrolled paint transfer, severely reduced coating accuracy, and ultimately uneven coating thickness. This not only weakens the fire resistance of the coating but also leads to appearance defects, reducing the product yield. Summary of the Invention

[0006] In view of the problems of poor adaptability to irregularly shaped glass and inability to synchronously adjust the distance between the coating roller and scraper and the glass in the existing technology, a fireproof coating machine and production process for fireproof glass production is proposed.

[0007] This application provides a fireproof coating machine for fireproof glass production. Its purpose is to provide a stable installation and conveying platform for the coating process through a base frame mechanism, and to enable the coating roller and scraper to follow the curved contour of the irregular glass in real time and synchronously by setting up a coating mechanism with independent servo drive and flexible contour design. This allows for automatic coordinated fine adjustment of the spacing and pressure, ensuring constant coating gap and precise control of coating transfer amount. This fundamentally achieves high uniformity and high precision coating, significantly improving the fireproof performance, appearance quality and production qualification rate of the product.

[0008] The technical solution of the present invention is as follows: a fireproof coating machine for fireproof glass production, comprising an equipment frame and a conveying assembly fixedly installed inside the equipment frame, and further comprising a base frame mechanism and a coating mechanism disposed above the conveying assembly. The base frame mechanism supports a glass sample inside, and the coating mechanism includes a paint supply device, wherein a plurality of support springs are fixedly connected between the paint supply device and the equipment frame.

[0009] The base frame mechanism includes a conveyor frame disposed on top of the conveying assembly, a bonding frame mounted on top of the conveyor frame, a bonding groove formed on the inner wall of the bonding frame, the inner wall of the bonding groove fitting the bottom contour of the glass sample, and an arc-shaped baffle fixedly connected to the outer wall of the bonding frame.

[0010] The paint supply device is internally equipped with a roller assembly and a scraper. The roller assembly includes a coating roller rotatably connected to the inner wall of the paint supply device. The coating roller is used to coat the surface of the glass sample.

[0011] Using the above scheme, the glass sample is fed in by the conveying component through the set base frame mechanism and coating mechanism, and is stably positioned and transported in the bonding groove of the base frame mechanism. The coating mechanism suspended above by the support spring is then started. The coating roller rolls the coating onto the glass surface, and the scraper performs fine scraping. The entire coating head can be passively and finely adjusted according to the glass contour. Combined with the precise positioning at the bottom, it achieves high adaptability and high uniformity of coating on irregularly shaped glass, directly improving the performance consistency of the fireproof coating and the product qualification rate.

[0012] Furthermore, both ends of the coating roller are rotatably connected to sliding bearings, and the outer walls of the sliding bearings are sequentially slidably connected to a first sliding sleeve, a second sliding sleeve, and a third sliding sleeve. The tops of the first sliding sleeve, the second sliding sleeve, and the third sliding sleeve are all fixedly connected to sliding frames. The outer walls of the multiple sliding frames are slidably connected to the inner walls of the paint supply device, and the inner walls of the multiple sliding frames are threaded with threaded rods. The multiple threaded rods are rotatably connected to the paint supply device, and the tops of the multiple sliding frames are fixedly connected to trapezoidal support blocks.

[0013] By adopting the above scheme, the coating roller is provided with multi-degree-of-freedom fine-tuning capability through the setting of sliding bearings and multi-stage sliding sleeve pairs. The sliding bearings ensure smooth rotation of the coating roller, while the precise nested structure formed by the first, second, and third sliding sleeves allows the two ends of the coating roller to generate slight radial floating and angular sway. This enables the coating roller to achieve local self-alignment when there are local unevenness or irregular contours on the glass surface, dynamically maintaining uniform and flexible contact with the glass surface along its entire length. This significantly improves the uniformity and consistency of the coating and effectively avoids uneven pressure or glass damage caused by rigid contact.

[0014] Furthermore, two symmetrically arranged lifting blocks are fixedly connected to the top of the scraper, and multiple telescopic springs are fixedly connected between the bottom of the two lifting blocks and the inner wall of the paint supply device. The outer walls of the two lifting blocks respectively abut against the top of the corresponding trapezoidal support block.

[0015] Furthermore, the roller assembly also includes a second servo motor fixedly mounted on the outer wall of the paint supply device, and the output shaft of the second servo motor is fixedly connected to the coating roller.

[0016] By adopting the above scheme, a closed-loop feedback linkage adjustment system is formed by the set scraper and trapezoidal support block, which ensures the gap between the scraper and the coating roller. Thus, while the coating roller self-aligns, the scraping effect is optimized simultaneously, ensuring the uniformity and stability of the paint supply, and ultimately improving the overall quality of the coating. At the same time, the output shaft of the second servo motor is fixedly connected to the coating roller, providing a precise and adjustable power source for the coating roller, ensuring that it rotates actively at a constant or preset variable speed, thereby stably picking up paint from the paint tank and transferring it to the glass surface.

[0017] Furthermore, the bottom of the conveyor frame is provided with a sliding groove, the inner wall of the sliding groove is slidably connected with a gravity block, and the bottom of the conveyor frame is fixedly connected with a plurality of equally spaced clips.

[0018] Furthermore, the conveying assembly includes two conveyor belts symmetrically arranged inside the equipment frame. The outer walls of the two conveyor belts are provided with multiple equally spaced slots, which are respectively engaged with corresponding clips. A cavity is formed between the two conveyor belts, and the gravity block is located inside the cavity.

[0019] By adopting the above scheme, the coordinated design of the conveyor frame and conveyor components achieves the dual effects of precise synchronous conveying and dynamic self-stabilization. The rigid engagement of the clamp and the groove ensures high-precision synchronous linear motion between the conveyor frame and the conveyor belt without slippage, providing a reliable positioning reference for processes such as coating. At the same time, the gravity block suspended in the chute and placed in the cavity utilizes its gravity and inertia to form a passive dynamic stabilization system, which can effectively suppress vibration and sway during the conveying process and significantly improve the stability and reliability of the equipment operation.

[0020] Furthermore, the conveying assembly also includes two drive rollers and two buffer rollers symmetrically arranged inside the equipment frame. The two drive rollers and two buffer rollers are rotatably connected to the inner wall of the equipment frame, and the two conveyor belts are respectively connected to the two drive rollers and two buffer rollers.

[0021] Furthermore, a first servo motor is fixedly connected to the outer wall of one of the transmission rollers, and the first servo motor is fixedly connected to the equipment frame. Low-friction plastic sleeves are fixedly connected to the outer walls of both buffer rollers, and both low-friction plastic sleeves are located inside the cavity.

[0022] By adopting the above scheme, the conveying components enable efficient, stable and controllable flexible material conveying. The first servo motor drives the transmission roller, providing precise and adjustable power to the conveyor belt and enabling precise control of start, stop and speed change. When the gravity block at the bottom of the conveyor frame contacts the low-friction plastic sleeve, the low-friction plastic sleeve blocks the movement of the gravity block. During the continuous movement of the conveyor frame, the gravity block slides along the chute, so that the conveyor frame always remains stable.

[0023] Another aspect of this application provides a production process for a fireproof coating machine for fireproof glass production, which includes the following steps: Step 1: When the glass sample is slightly curved glass, a corresponding bonding frame is installed on the conveyor frame and the glass sample is placed.

[0024] Step 2: Place the conveyor frame onto the conveyor assembly manually or with a robotic arm.

[0025] Step 3: Adjust the distance between the coating roller and scraper and the bonding frame using the roller assembly to control the coating thickness.

[0026] Step 4: Operate the conveyor assembly to transport the glass sample to the bottom of the coating roller via the conveyor frame.

[0027] Step 5: The coating roller moves along the curve of the bonding frame surface to coat the surface of the glass sample.

[0028] Step 6: Coating complete, remove the conveyor.

[0029] Step 7: When the glass sample is a flat glass, simply place the glass sample on the conveyor frame.

[0030] The beneficial effects of this invention are as follows: The three-level nested floating structure composed of the first, second, and third sliding sleeves provides the coating roller with multi-degree-of-freedom self-aligning capability. When irregularly shaped glass passes through, the coating roller can passively and adaptively float along its curved contour, always conforming to the glass surface. At the same time, the entire coating head is flexibly suspended by multiple support springs, providing overall buffering. This structure enables the coating pressure to be dynamically and evenly distributed along the glass contour, solving the problems of accumulation at protrusions and missed coating at depressions. It ensures the uniform transfer of fire-retardant coating on irregularly shaped surfaces, ultimately obtaining a high-quality coating with consistent thickness and continuous integrity.

[0031] By using the inclined surface abutment structure of the lifting blocks at both ends of the scraper and the trapezoidal support block of the coating roller, a mechanical closed-loop feedback is formed. When the sliding sleeve is adjusted, the displacement of the trapezoidal block drives the lifting block through the inclined surface, which in turn drives the scraper to rise and fall synchronously. This linkage mechanism enables the scraper gap to automatically and finely adjust in real time to follow the position of the coating roller, maintaining the coordination between the two. The structure solves the problem of fixed gap and inability to follow the movement of traditional devices, realizes accurate secondary metering after coating transfer, achieves ultra-high precision control of coating thickness, and significantly improves the product qualification rate.

[0032] The rigid meshing structure between the bottom clamp of the conveyor frame and the conveyor belt groove enables zero-slip synchronous transmission, providing a precise linear motion reference for the glass. At the same time, the passive damping system formed by the gravity block in the chute and the conveyor belt cavity utilizes the inertia of the gravity block to generate an anti-phase damping force, absorbing equipment vibration. This combination of structures not only ensures the accuracy of the conveying path but also effectively suppresses swaying and impact during operation, achieving absolutely stable operation in the coating area. This provides a key guarantee for obtaining a coating with clear edges and uniform thickness. Attached Figure Description

Detailed Implementation

[0048] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0049] Reference Figure 1- Figure 14 The first embodiment of the present invention provides a fireproof coating machine for fireproof glass production, including a frame 1 and a conveying assembly 2 fixedly installed inside the frame 1. It also includes a base frame mechanism 3 and a coating mechanism 5 disposed above the conveying assembly 2. The base frame mechanism 3 supports a glass sample 4. The coating mechanism 5 includes a paint supply device 52. A plurality of support springs 51 are fixedly connected between the paint supply device 52 and the frame 1.

[0050] Reference Figure 5 - Figure 14 The base frame mechanism 3 includes a conveyor frame 31 mounted on top of the conveyor assembly 2. A bonding frame 34 is mounted on top of the conveyor frame 31. A bonding groove 341 is provided on the inner wall of the bonding frame 34. The inner wall of the bonding groove 341 is fitted with the bottom contour of the glass sample 4. An arc-shaped baffle 342 is fixedly connected to the outer wall of the bonding frame 34. The paint supply device 52 is equipped with a roller assembly 53 and a scraper 54. The roller assembly 53 includes a coating roller 532 rotatably connected to the inner wall of the paint supply device 52. The coating roller 532 is used to coat the surface of the glass sample 4.

[0051] Specifically, the bonding groove 341 ensures that the glass is stably supported and positioned during transport, maintaining a consistent relative position with the upper coating mechanism 5, thus laying a stable foundation for subsequent uniform coating. The arc-shaped baffle 342 on the outer wall of the bonding frame 34 acts as a buffer, providing a smooth transition during the initial contact between the coating roller 532 and the glass sample 4, preventing rigid impact. The surface of the coating roller 532 is coated with a flexible microporous material, continuously contacting the fire-retardant coating from the supply device. When the glass sample 4 passes through the coating roller 532 under the transport of the base frame mechanism 3, the rotating coating roller 532... 32. A fixed amount of coating is evenly transferred to the glass surface. Immediately afterwards, the scraper 54 acts on the glass surface with a precisely adjustable angle and spacing to scrape off excess coating, thereby accurately controlling the thickness of the final coating. The coating supply device 52 is elastically suspended on the equipment frame 1 by multiple support springs 51, forming a passive adaptive system. When encountering slight undulations or irregular contours on the glass surface, the entire coating head composed of the coating roller 532 and the scraper 54 can float up and down slightly under the buffering effect of the springs, thereby dynamically maintaining a constant contact pressure or gap with the glass surface.

[0052] Through the base frame mechanism 3 and coating mechanism 5, the glass sample 4 is fed in by the conveying component 2 and stably positioned in the bonding groove 341 of the base frame mechanism 3. The coating mechanism 5, which is suspended above by the support spring 51, is then activated. The coating roller 532 rolls the coating onto the glass surface, and the scraper 54 performs fine scraping. The entire coating head can be passively and slightly adjusted according to the glass contour. Combined with the precise positioning at the bottom, it achieves high adaptability and high uniformity of coating on irregularly shaped glass, directly improving the performance consistency and product qualification rate of the fireproof coating.

[0053] Reference Figure 9 - Figure 14 Both ends of the coating roller 532 are rotatably connected to sliding bearings 533. The outer walls of the sliding bearings 533 are sequentially slidably connected to a first sliding sleeve 534, a second sliding sleeve 535, and a third sliding sleeve 536. The tops of the first sliding sleeve 534, the second sliding sleeve 535, and the third sliding sleeve 536 are all fixedly connected to sliding frames 537. The outer walls of the multiple sliding frames 537 are slidably connected to the inner walls of the paint supply device 52. The inner walls of the multiple sliding frames 537 are threadedly connected to threaded rods 538. The multiple threaded rods 538 are rotatably connected to the paint supply device 52. The tops of the multiple sliding frames 537 are all fixedly connected to trapezoidal support blocks 539.

[0054] Specifically, the sliding bearing 533 allows the coating roller 532 to rotate freely in its inner hole; a first sliding sleeve 534, a second sliding sleeve 535 and a third sliding sleeve 536 are sequentially fitted on the outer wall of the sliding bearing 533, forming a multi-level nested sliding pair; the sliding frame 537 at the top of each sliding sleeve is connected to an independent threaded rod 538 by threads, and the two ends of the threaded rod 538 are supported by the housing of the paint supply device 52 and can be rotated by a handwheel.

[0055] The sliding bearing 533 and the multi-stage sliding sleeve pair provide the coating roller 532 with multi-degree-of-freedom fine-tuning capability. The sliding bearing 533 ensures the smooth rotation of the coating roller 532, while the precise nested structure formed by the first sliding sleeve 534, the second sliding sleeve 535 and the third sliding sleeve 536 allows the coating roller 532 to generate slight radial floating and angular sway at both ends. This enables the coating roller 532 to achieve local self-alignment when there are local unevenness or irregular contours on the glass surface, and dynamically maintain uniform and flexible contact with the glass surface along its entire length. This significantly improves the uniformity and consistency of the coating and effectively avoids uneven pressure or glass damage caused by rigid contact.

[0056] Reference Figure 10 - Figure 14The top of the scraper 54 is fixedly connected to two symmetrically arranged lifting blocks 541. The bottom of the two lifting blocks 541 is fixedly connected to the inner wall of the paint supply device 52, and the outer walls of the two lifting blocks 541 respectively abut against the top of the corresponding trapezoidal support block 539. The roller assembly 53 also includes a second servo motor 531 fixedly installed on the outer wall of the paint supply device 52. The output shaft of the second servo motor 531 is fixedly connected to the coating roller 532.

[0057] Specifically, two lifting blocks 541 are fixed to the top of the scraper 54, and their bottoms are elastically connected to the inner wall of the paint supply device 52 through multiple telescopic springs 542, so that they can obtain an upward elastic preload. At the same time, the outer wall slope of the lifting block 541 continuously abuts against the top slope of the corresponding trapezoidal support block 539. When the trapezoidal support block 539 moves with the sliding frame 537, it transmits the pressure to the lifting block 541 through the slope, thereby compressing or releasing the telescopic springs 542 below it, so that the scraper 54 produces relative displacement.

[0058] The scraper 54 and trapezoidal support block 539 form a closed-loop feedback linkage adjustment system, which ensures the gap between the scraper 54 and the coating roller 532. This allows the coating roller 532 to self-align and optimize the scraping effect simultaneously, ensuring uniform and stable paint supply and ultimately improving the overall coating quality. At the same time, the output shaft of the second servo motor 531 is fixedly connected to the coating roller 532, providing a precise and adjustable power source for the coating roller 532. This ensures that the roller rotates actively at a constant or preset speed, thereby stably picking up paint from the paint tank and transferring it to the glass surface.

[0059] Reference Figure 2 - Figure 6 The bottom of the conveyor frame 31 is provided with a groove 311, and a gravity block 33 is slidably connected to the inner wall of the groove 311. Multiple equally spaced locking strips 32 are fixedly connected to the bottom of the conveyor frame 31. The conveyor assembly 2 includes two conveyor belts 24 symmetrically arranged inside the equipment frame 1. Multiple equally spaced locking slots 25 are provided on the outer wall of each of the two conveyor belts 24. The multiple locking slots 25 are respectively engaged with the corresponding locking strips 32. A cavity 26 is formed between the two conveyor belts 24, and the gravity block 33 is located inside the cavity 26.

[0060] Specifically, the bottom of the conveyor frame 31 is fixed with multiple clips 32, and the surfaces of the two parallel conveyor belts 24 are provided with matching slots 25. The clips 32 and the slots 25 correspond one to one and mesh with each other. The bottom of the conveyor frame 31 is provided with a chute 311, in which a gravity block 33 that can slide along the chute is suspended. A cavity 26 is reserved between the two conveyor belts 24, and the gravity block 33 is suspended in this cavity 26.

[0061] Through the coordinated design of the conveyor frame 31 and the conveyor assembly 2, the dual effects of precise synchronous conveying and dynamic self-stabilization are achieved. The rigid engagement of the clip 32 and the slot 25 ensures high-precision synchronous linear motion between the conveyor frame 31 and the conveyor belt 24 without slippage, providing a reliable positioning reference for processes such as coating. At the same time, the gravity block 33, suspended in the chute 311 and placed in the cavity 26, uses its gravity and inertia to form a passive dynamic stabilization system, which can effectively suppress vibration and sway during the conveying process and significantly improve the stability and reliability of the equipment operation.

[0062] Reference Figure 2 - Figure 4 The conveying assembly 2 also includes two drive rollers 22 and two buffer rollers 23 symmetrically arranged inside the equipment frame 1. The two drive rollers 22 and the two buffer rollers 23 are rotatably connected to the inner wall of the equipment frame 1. The two conveyor belts 24 are respectively connected to the two drive rollers 22 and the two buffer rollers 23. A first servo motor 21 is fixedly connected to the outer wall of one of the drive rollers 22. The first servo motor 21 is fixedly connected to the equipment frame 1. Low-friction plastic sleeves 231 are fixedly connected to the outer walls of the two buffer rollers 23. The two low-friction plastic sleeves 231 are located inside the cavity 26.

[0063] The conveying component 2 enables efficient, stable, and controllable flexible material conveying. The first servo motor 21 drives the transmission roller 22, providing precise and adjustable power to the conveyor belt 24, and achieving precise control of start-stop and speed change. When the gravity block 33 at the bottom of the conveyor frame 31 contacts the low-friction plastic sleeve 231, the low-friction plastic sleeve 231 blocks the movement of the gravity block 33. During the continuous movement of the conveyor frame 31, the gravity block 33 slides along the chute 311, so that the conveyor frame 31 always remains stable.

[0064] Reference Figure 1 - Figure 14 The second embodiment of the present invention provides a production process for a fireproof coating machine for fireproof glass production. The fireproof coating machine for fireproof glass production includes the following steps: Step 1: When the glass sample 4 is slightly curved glass, a corresponding bonding frame 34 is installed on the conveyor frame 31 and the glass sample 4 is placed thereon.

[0065] Step 2: Place the conveyor frame 31 onto the conveyor assembly 2 manually or with a robotic arm.

[0066] Step 3: Adjust the distance between the coating roller 532 and the scraper 54 and the bonding frame 34 by using the roller assembly 53 to control the coating thickness.

[0067] Step 4: Operate the conveyor assembly 2 to convey the glass sample 4 to the bottom of the coating roller 532 via the conveyor frame 31.

[0068] Step 5: The coating roller 532 moves along the surface curve of the bonding frame 34 to coat the surface of the glass sample 4.

[0069] Step 6: Coating complete, remove conveyor 31.

[0070] Step 7: When the glass sample 4 is a flat glass, simply place the glass sample 4 directly on the conveyor frame 31.

[0071] The working principle of the present invention is as follows: When the glass sample 4 is a micro-curved glass, the operator first installs the corresponding bonding frame 34 on the conveyor frame 31. The inner wall of the bonding frame 34 is provided with a bonding groove 341, the shape of which is precisely matched with the bottom contour of the micro-curved glass, so that the glass sample 4 can be stably embedded therein, thereby realizing the rapid adaptation of the micro-curved glass and providing a bearing foundation for subsequent uniform coating.

[0072] The conveyor frame 31 carrying the glass sample 4 is moved onto the conveyor assembly 2 by manual labor or a robotic arm. The bottom of the conveyor frame 31 is provided with multiple equidistant locking strips 32, and the outer surface of the conveyor belt 24 is provided with corresponding locking grooves 25. When the locking strips 32 are embedded in the locking grooves 25, the conveyor frame 31 and the conveyor belt 24 form a stable meshing connection, avoiding relative slippage during the conveying process. At the same time, a gravity block 33 is provided in the slide groove 311 at the bottom of the conveyor frame 31. The gravity block 33 provides an additional vertical downward stabilizing force for the conveyor frame 31 by gravity, ensuring that the conveyor frame 31 can maintain stable operation even when subjected to the pressure of the coating roller 532 when passing through the coating area.

[0073] Before coating, first rotate the threaded rod 538 corresponding to the third sliding sleeve 536, and drive the third sliding sleeve 536 to slide on the outer wall of the sliding bearing 533 through the corresponding sliding bracket 537 to obtain the first level of thickness; then rotate the threaded rod 538 corresponding to the second sliding sleeve 535, and drive the second sliding sleeve 535 to slide on the outer wall of the third sliding sleeve 536 through the corresponding sliding bracket 537 to obtain the second level of thickness; then rotate the threaded rod 538 corresponding to the first sliding sleeve 534, and drive the first sliding sleeve 534 to slide on the outer wall of the second sliding sleeve 535 through the corresponding sliding bracket 537 to obtain the third level of thickness; thus, the thickness can be adjusted according to different coating thickness requirements.

[0074] Meanwhile, in its natural state, the telescopic spring 542 keeps the scraper 54 in the lower position. When the sliding frame 537 moves horizontally towards the center of the coating roller 532, the inclined surface of the trapezoidal support block 539 contacts the lifting block 541 and gradually lifts it upward, thereby overcoming the elastic force of the telescopic spring 542 and lifting the scraper 54 to a position that matches the thickness of each grade. By moving the sliding frame 537 horizontally to different positions, the gap between the scraper 54 and the coating roller 532 and the bonding frame 34 can be set in a coordinated manner, realizing the integrated preset of coatings of different thicknesses.

[0075] After the parameters are set, the first servo motor 21 is started. The first servo motor 21 drives the transmission roller 22 to rotate, which drives the two conveyor belts 24 to operate synchronously. The conveyor belts 24 smoothly transport the conveyor frame 31 and the glass sample 4 it carries, so that it enters the working area of ​​the coating mechanism 5 directly below, that is, the coating roller 532.

[0076] When the glass sample 4 is conveyed to the area directly below the coating roller 532, the second servo motor 531 starts and drives the coating roller 532 to rotate at high speed. The paint supply device 52 continuously supplies fire-retardant paint to the surface of the coating roller 532. Under the support of the support spring 51, the arc-shaped baffle 342 at the front end of the bonding frame 34 lifts the coating roller 532, so that the coating roller 532 moves on the upper surface of the bonding frame 34 at a preset interval to coat the glass sample 4. The scraper 54 that follows can evenly scrape off the excess paint on the surface of the glass sample 4, thereby forming a fire-retardant coating with a uniform thickness and conforming to the preset thickness on the surface of the glass sample 4.

[0077] After the coating operation is completed, the conveyor belt 24 continues to transport the conveyor frame 31 and the coated glass sample 4 out of the coating area. When the gravity block 33 at the bottom of the conveyor frame 31 comes into contact with the low-friction plastic sleeve 231, the low-friction plastic sleeve 231 blocks the movement of the gravity block 33. During the continuous movement of the conveyor frame 31, the gravity block 33 slides along the slide groove 311, so that the conveyor frame 31 always remains stable. Then, the operator removes the conveyor frame 31 from the conveyor belt 24.

[0078] When the glass sample 4 is a flat glass, the installation of the bonding frame 34 can be omitted, and the flat glass can be placed directly on the flat top surface of the conveyor frame 31.

[0079] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
