This device requires minimal manpower, is easy to operate, and improves spraying efficiency.

Description

Technical Field

[0001] This invention relates to the field of fire-resistant glass preparation technology, specifically to an apparatus for preparing a fire-resistant layer by spraying fire-resistant coating on single-layer fire-resistant glass. Background Technology

[0002] Fire-resistant glass primarily functions to control the spread of fire or block smoke during fire prevention. It is a type of fire-resistant material used as a preventative measure, and its fire-resistant effect is evaluated based on its fire resistance performance. It is a special type of glass that has undergone special processing and treatment to maintain its integrity and thermal insulation properties during specified fire resistance tests. The base glass for fire-resistant glass can be float glass, while composite fire-resistant glass can also be made from monolayer fire-resistant glass. Monolayer fire-resistant glass is a type of fire-resistant glass with a single-layer glass structure. It maintains its fire resistance integrity for a certain period, blocking open flames and toxic or harmful gases from the fire-facing surface, but it does not provide thermal insulation.

[0003] In the specific process of preparing single-pane fireproof glass, several pieces of glass are placed at an angle on a glass production rack. The outer surface of the outermost piece of glass is sprayed with a spray bottle. After spraying, two workers lift the sprayed glass to another empty glass production rack. The outermost piece of glass is then sprayed again, and two workers lift it to another empty glass production rack. This process is repeated until all the pieces on a glass production rack are sprayed. However, this method has the following drawbacks: the spraying time is too long, a large amount of manpower is required, the operation is cumbersome, and the spraying efficiency is low.

[0004] In summary, there is a current need for a fire-resistant coating preparation device for single-layer fire-resistant glass. Summary of the Invention

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] To address the technical problems in the background section, the following apparatus for preparing the fireproof layer of single-layer fireproof glass by spraying is provided:

[0036] Combination Figures 1-6 As shown, the present invention includes a frame 1, which includes a base frame 11. A pulley 112 is fixed on the side wall of the base frame 11 perpendicular to the connecting rod 14. A plurality of casters 111 are fixed on the bottom surface of the base frame 11. An outer frame 12 is provided on the outside of the base frame 11. The base frame 11 is fixed to the outer frame 12 by a plurality of connecting rods 14. A top frame 13 is fixed on the top of the outer frame 12. A handle 121 is fixed on the side wall of the outer frame 12 to facilitate the operator to pull the handle 121 to move the frame 1.

[0037] The frame 1 has a first shelf 7 and a second shelf 8 on each side. The first shelf 7 and the second shelf 8 are used to place glass 9. The first shelf 7 and the second shelf 8 each include several horizontal bars 71 and several vertical bars 72. The horizontal bars 71 are all inclined. A straight plate 73 is fixed between two straight bars. The side walls of the first shelf 7 and the second shelf 8 are all fixed with slide rails 74 that cooperate with pulleys 112. The side of the base frame 11 that is parallel to the connecting rod 14 is higher than the horizontal bars 71, so as to ensure that the frame 1 can be moved above the first shelf 7.

[0038] Before the spraying begins: the first rack 7 is filled with unsprayed glass 9, and the second rack 8 is not filled with glass 9. The first rack 7 and the second rack 8 are placed symmetrically so that the pulley 112 of the frame 1 enters the slide rail 74 of the second rack 8. The pulley 112 slides in the slide rail 74 of the second rack 8 until the pulley 112 of the frame 1 slides into the slide rail 74 of the first rack 7. At this time, the two ends of the frame 1 are respectively above the first rack 7 and the second rack 8.

[0039] The bottom surfaces of the two side walls of the base frame 11, which are parallel to the connecting rod 14, are respectively provided with a second vacuum suction cup 5 and a third vacuum suction cup 6. The second vacuum suction cup 5 and the third vacuum suction cup 6 are both fixedly connected to the inlet end of the vacuum pump 29.

[0040] In the above technical solution, the second vacuum suction cup 5, the third vacuum suction cup 6 and the first vacuum suction cup 28 used to adsorb glass 9 are all connected to the vacuum pump 29. When the vacuum pump 29 is turned on, it controls the first vacuum suction cup 28, the second vacuum suction cup 5 and the third vacuum suction cup 6 to work simultaneously. When the first vacuum suction cup 28 adsorbs glass 9, the second vacuum suction cup 5 adsorbs the first mounting frame 7 and the third vacuum suction cup 6 adsorbs the second mounting frame 8 to perform positioning and prevent relative sliding between the first mounting frame 7, the second mounting frame 8 and the frame 1.

[0041] When the first vacuum suction cup 28 fails to hold the glass 9, the second vacuum suction cup 5 fails to hold the first mounting frame 7, and the third vacuum suction cup 6 fails to hold the column second mounting frame 8, the frame 1 can be moved to adjust its position between the first mounting frame 7 and the second mounting frame 8.

[0042] Example 2

[0043] like Figures 1-10 As shown, based on the above embodiments, this embodiment further provides the following:

[0044] To enable the glass 9 to be transferred from the first shelf 7 to the second shelf 8, this embodiment provides the following design: It also includes a transfer assembly 2, which is mounted on the top frame 13. The transfer assembly 2 includes a first movable seat 21 and symmetrically arranged first vacuum suction cups 28. The first movable seat 21 is provided with a first driving assembly 24, which is used to drive the first vacuum suction cups 28 to move in parallel. Guide plates 26 are symmetrically fixed below the top frame 13. A second driving assembly 25 is provided between the two guide plates 26, which is used to drive the first movable seat 21 to move along the guide plates 26.

[0045] A second movable seat 22 is provided above the first movable seat 21. The first movable seat 21 is fixedly connected to the second movable seat 22 through a number of connecting posts 23. The second drive assembly 25 includes a sliding post 251, a third lead screw 252, and a second motor 253. The bottom end of the sliding post 251 is slidably located in the middle of the second movable seat 22. The third lead screw 252 passes through the sliding post 251 and is threadedly connected to the sliding post 251. A second motor 253 for driving the third lead screw 252 to rotate is installed below the top frame 13.

[0046] A fixing rod 27 is fixedly provided at the inner end of the first vacuum suction cup 28. The top end of the fixing rod 27 is slidably located in the first movable seat 21. The first drive assembly 24 includes a first lead screw 241 and a second lead screw 242. Both the first lead screw 241 and the second lead screw 242 are rotatably located in the first movable seat 21. A first passive bevel tooth 243 is fixed at the inner end of the first lead screw 241, and a second passive bevel tooth 244 is fixed at the inner end of the second lead screw 242. An active bevel tooth 245 meshes between the first passive bevel tooth 243 and the second passive bevel tooth 244. A first motor 246 for driving the active bevel tooth 245 to rotate is installed on the outer wall of the first movable seat 21.

[0047] The first movable seat 21 is symmetrically fixed with a first limiting plate 211 inside. A second limiting plate 212 is provided between the two first limiting plates 211. The second limiting plate 212 is fixed to the inner side wall of the first movable seat 21. The first lead screw 241 and the second lead screw 242 pass through the two first limiting plates 211 respectively. The ends of the first lead screw 241 and the second lead screw 242 are respectively rotated into the second limiting plate 212. The fixing rod 27 is located between the first limiting plate 211 and the inner side wall of the first movable seat 21. The top of the top plate is provided with a vacuum pump 29. The inlet end of the vacuum pump 29 is connected to the first vacuum suction cup 28.

[0048] The inner sidewall of the guide plate 26 is provided with an inclined guide groove 262 and a straight guide groove 261. Both ends of the straight guide groove 261 are provided with inclined guide grooves 262. The height of the end of the inclined guide groove 262 is lower than the height of the straight guide groove 261. Both ends of the second movable seat 22 are fixed with guide posts 221. The guide posts 221 slide on the guide plate 26. The inclined guide grooves 262 cause the first movable seat 21 to move in parallel while its height increases, so that the glass 9 can rise to a certain height when moving in parallel, preventing the base frame 11 from obstructing the movement of the glass 9.

[0049] In the above technical solution, the vacuum pump 29 is turned on. Under the action of the vacuum pump 29, the first vacuum suction cup 28 picks up the glass 9 on the first mounting frame 7. The second motor 253 is turned on, and the second motor 253 drives the third lead screw 252 to rotate. The third lead screw 252 drives the sliding column 251 to move. The sliding column 251 drives the second moving seat 22 and the first moving seat 21 to move. The second moving seat 22 moves obliquely upward along the inclined guide groove 262 and then moves parallel along the straight guide groove 261. The movement of the second moving seat 22 causes the bottom end of the sliding column 251 to extend into the second moving seat 22. The second moving seat 22 drives the first moving seat 21 to move obliquely upward. The first moving seat 21, through the fixed rod 27 and the first vacuum suction cup 28, drives the glass 9 to move obliquely upward and then move parallel. 9 gradually approaches the second mounting frame 8 until the second movable seat 22 moves again to the inclined guide groove 262. The second movable seat 22 moves diagonally downward. The movement of the second movable seat 22 causes the bottom end of the sliding column 251 to extend into the second movable seat 22. The second movable seat 22 drives the first movable seat 21 to move diagonally downward. The first movable seat 21 drives the glass 9 to move diagonally downward through the fixed rod 27 and the first vacuum suction cup 28. The bottom end of the glass 9 approaches the horizontal rod 71 of the second mounting frame 8. The lever 43 assembly is activated. When the lever 43 contacts the top of the glass 9, the vacuum pump 29 is turned off. The glass 9 is then placed on the second mounting frame 8. The lever 43 causes the glass 9 to tilt towards the vertical rod 72 of the second vacuum glass 9 until it contacts the vertical plate. The glass 9 is then smoothly transferred to the second mounting frame 8.

[0050] When the first motor 246 is turned on, its output shaft drives the active bevel gear 245 to rotate. The active bevel gear 245 drives the first passive bevel gear 243 and the second passive bevel gear 244 to rotate simultaneously and in opposite directions. The first passive bevel gear 243 and the second passive bevel gear 244 drive the first lead screw 241 and the second lead screw 242 to rotate, respectively. The first lead screw 241 and the second lead screw 242 drive the two fixed rods 27 to move in opposite directions, respectively. The two fixed rods 27 drive the two first vacuum suction cups 28 to move in opposite directions until the first vacuum suction cups 28 move to the outermost edge of the first moving seat 21. At this time, the second motor 253 is started again, causing it to drive the third lead screw 252 to rotate in the opposite direction. The sliding column 251 moves towards the first mounting frame 7, thereby resetting the first vacuum suction cups 28.

[0051] Example 3

[0052] like Figures 1-5As shown, based on the above embodiments, this embodiment further provides the following: A spraying assembly 3 is provided, mounted on a top frame 13. The spraying assembly 3 includes a movable main pipe 31, with several nozzles 32 fixedly connected to the inner wall of the movable main pipe 31. A third motor 37 for driving the movable main pipe 31 to move vertically is provided on the top frame 13. A fourth lead screw 33 and a slide rod 34 are respectively provided at both ends of the movable main pipe 31. The fourth lead screw 33 passes through the movable main pipe 31 and is threadedly connected to it. The slide rod 34 slides through the movable main pipe 31. A liquid storage tank 36 and a high-pressure pump 35 are provided at the top of the top frame 13. The inlet end of the high-pressure pump 35 is connected to the liquid storage tank 36, and the outlet end of the high-pressure pump 35 is connected to the movable main pipe 31.

[0053] In the above technical solution, the third motor 37 and the high-pressure pump 35 are turned on. The output shaft of the third motor 37 drives the fourth lead screw 33 to rotate. The fourth lead screw 33 drives the moving main pipe 31 to move downward. The end of the moving main pipe 31 slides downward along the slide bar 34. The high-pressure pump 35 causes the fireproof coating in the liquid storage tank 36 to be sprayed onto the surface of the glass 9 through several nozzles 32. The moving main pipe 31 moves from the top frame 13 to the bottom frame 11, so that the several nozzles 32 coat the entire glass 9 from top to bottom.

[0054] To ensure that the glass 9 can rest stably against the vertical rod 72 of the second shelf 8 when the transfer assembly 2 transfers the glass 9 to the second shelf 8, this embodiment provides the following design: The bottom surface of the top frame 13 is provided with a toggle assembly 4, which includes a mounting base 41, an electric cylinder 42, and a toggle rod 43. The toggle rod 43 is used to tilt the glass 9 towards the second shelf 8. The mounting base 41 is fixed to the bottom surface of the top frame 13. The cylinder body of the electric cylinder 42 is rotatably connected to the mounting base 41. The upper end of the toggle rod 43 is rotatably connected to the mounting base 41. The piston rod of the electric cylinder 42 is rotatably connected to the toggle rod 43. When the electric cylinder 42 is activated, the piston rod of the electric cylinder 42 pushes the toggle rod 43 to rotate. The cylinder body of the electric cylinder 42 rotates simultaneously. When the toggle rod 43 rotates to contact the glass 9, it tilts the glass 9 so that the glass 9 moves closer to the vertical rod 72 of the second shelf 8, allowing the glass 9 to be placed stably on the second shelf 8.

[0055] Working principle and usage process of this invention:

[0056] Step 1:

[0057] The first rack 7 is filled with uncoated glass 9, and the second rack 8 is not filled with glass 9. The first rack 7 and the second rack 8 are placed symmetrically so that the pulley 112 of the frame 1 enters the slide rail 74 of the second rack 8. The pulley 112 slides in the slide rail 74 of the second rack 8 until the pulley 112 of the frame 1 slides into the slide rail 74 of the first rack 7. At this time, the two ends of the frame 1 are respectively above the first rack 7 and the second rack 8.

[0058] Step Two:

[0059] Turn on vacuum pump 29. Under the action of vacuum pump 29, first vacuum suction cup 28 picks up glass 9 on first mounting frame 7, second vacuum suction cup 5 picks up first mounting frame 7, and third vacuum suction cup 6 picks up second mounting frame 8 for positioning. Turn on second motor 253. Second motor 253 drives third lead screw 252 to rotate. Third lead screw 252 drives sliding column 251 to move. Sliding column 251 drives second moving seat 22 and first moving seat 21 to move. Second moving seat 22 moves obliquely upward along inclined guide groove 262 and then moves parallel along straight guide groove 261. The movement of second moving seat 22 causes the bottom end of sliding column 251 to extend into second moving seat 22. Second moving seat 22 drives first moving seat 21 to move obliquely upward. First moving seat 21, through fixed rod 27 and first vacuum suction cup 28, drives glass 9 to move obliquely upward to straight guide groove 261. Turn off second motor 253.

[0060] Step 3:

[0061] The third motor 37 and the high-pressure pump 35 are turned on. The output shaft of the third motor 37 drives the fourth lead screw 33 to rotate. The fourth lead screw 33 drives the moving main pipe 31 to move downward. The end of the moving main pipe 31 slides downward along the slide bar 34. The high-pressure pump 35 sprays the fireproof coating in the liquid storage tank 36 onto the surface of the glass 9 through several nozzles 32. The moving main pipe 31 moves from the top frame 13 to the bottom frame 11, so that the several nozzles 32 coat the entire glass 9 from top to bottom.

[0062] Step Four:

[0063] The second motor 253 is restarted, and the third lead screw 252 drives the sliding column 251 to move. The sliding column 251 drives the second moving seat 22 and the first moving seat 21 to move. The glass 9 gradually moves closer to the second mounting frame 8 until the second moving seat 22 moves to the inclined guide groove 262 again. The second moving seat 22 moves diagonally downward. The movement of the second moving seat 22 causes the bottom end of the sliding column 251 to extend into the second moving seat 22. The second moving seat 22 drives the first moving seat 21 to move diagonally downward. The first moving seat 21 drives the glass 9 to move diagonally downward through the fixed rod 27 and the first vacuum suction cup 28. The bottom end of the glass 9 moves closer to the horizontal rod 71 of the second mounting frame 8.

[0064] When the lever 43 assembly is activated, the piston rod of the electric cylinder 42 pushes the lever 43 to rotate, and the cylinder body of the electric cylinder 42 rotates at the same time. When the lever 43 rotates to contact the glass 9, it moves the glass 9 closer to the vertical rod 72 of the second shelf 8. When the lever 43 contacts the top of the glass 9, the vacuum pump 29 is turned off, and the glass 9 is placed on the second shelf 8.

[0065] Step 5:

[0066] When the first motor 246 is turned on, the output shaft of the first motor 246 drives the active bevel gear 245 to rotate. The active bevel gear 245 drives the first passive bevel gear 243 and the second passive bevel gear 244 to rotate simultaneously and in opposite directions. The first passive bevel gear 243 and the second passive bevel gear 244 drive the first lead screw 241 and the second lead screw 242 to rotate respectively. The first lead screw 241 and the second lead screw 242 drive the two fixed rods 27 to move in opposite directions respectively. The two fixed rods 27 drive the two first vacuum suction cups 28 to move in opposite directions until the first vacuum suction cups 28 move to the outermost edge of the first moving seat 21. At this time, the second motor 253 is started again, so that the second motor 253 drives the third lead screw 252 to rotate in the opposite direction. The sliding column 251 moves towards the first mounting frame 7, thereby resetting the first vacuum suction cups 28.

[0067] At this point, one spraying operation is complete. Hold the handle 121 and move the frame 1 toward the first mounting frame 7 until the first vacuum suction cup 28 contacts the outermost glass 9 on the first mounting frame 7, then spraying can be performed again.
