Description

Technical Field

[0001] This application relates to the field of fireproof door and window processing technology, and in particular to a fixing device for fireproof door and window painting. Background Technology

[0002] In the production process of fireproof doors and windows, painting is a crucial step, aimed at improving the aesthetics and protective performance of the doors and windows. Existing fireproof door and window painting and fixing devices are mostly simple in structure, merely using simple clamps to secure the doors and windows. This method has many shortcomings, such as insecure fixing, causing the doors and windows to shake during painting, resulting in uneven painting and affecting product quality. Furthermore, the fixing method is limited and cannot adapt to fireproof doors and windows of different sizes and shapes, exhibiting poor versatility. Additionally, the existing devices are cumbersome to operate, requiring significant manpower and time, thus reducing production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a fixing device for spraying paint on fireproof doors and windows in order to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows:

[0005] This application provides a fixing device for spraying fireproof doors and windows, including a workbench, a fixing component, a lifting component, a clamping component, and a spraying machine. Fixing plates are provided on both sides above the workbench, and a top plate is fixedly connected between the two fixing plates. Two sets of clamping components are provided and are installed on the two sets of fixing plates. The fixing component, clamping component, and spraying machine are all located above the workbench. The fixing component and clamping component are arranged in an orthogonal direction, and the clamping component is located between the spraying machine and the workbench.

[0006] Two sets of lifting components are symmetrically distributed on the inner bottom of the worktable. The worktable has an opening located above the two sets of lifting components. The lower part of the top plate is provided with a moving groove. Through holes communicating with the moving groove are provided on both sides of the top plate. A partition block is provided in the middle of the moving groove. Limiting grooves are provided at both ends of the partition block. A screw bearing seat is provided in the limiting groove. The partition block forms two sets of spaced receiving grooves in the moving groove. Two sets of fixing components are provided and located in the two sets of receiving grooves respectively.

[0007] The fixed assembly includes a threaded adjusting shaft, a sliding block, and an L-shaped limiting block. Two sets of threaded adjusting shafts are rotatably installed in the receiving groove. One end of the threaded adjusting shaft is installed on the lead screw bearing seat, and the other end extends through the through hole to the outside of the top plate. The sliding block is movably connected to the threaded adjusting shaft and connected to the L-shaped limiting block. By rotating the threaded adjusting shaft, the sliding block can move relative to the receiving groove, thereby driving the synchronous movement of the L-shaped limiting block.

[0008] The clamping assembly includes a worm gear component, a lead screw, a mounting plate, and electric grippers. The electric grippers are movably mounted on the mounting plate, and the lead screw is rotatably mounted on the fixed plate and connected to the worm gear component. Through the cooperation of the worm gear component and the lead screw, the two sets of electric grippers can move closer or further apart.

[0009] In one embodiment, the lower end of the sliding block is provided with a fitting opening, and the L-shaped limiting block is provided with a connecting protrusion. Through the fastening connection between the connecting protrusion and the fitting opening, the L-shaped limiting block can be installed or removed from the sliding block.

[0010] In one embodiment, the clamping assembly further includes a rotary cylinder disposed between the mounting plate and the electric gripper. The bottom of the electric gripper is provided with a slot, and the rotary cylinder is provided with a mounting block. The electric gripper can be installed or removed from the rotary cylinder through the snap-fit ​​connection between the slot and the mounting block.

[0011] In one embodiment, the lifting assembly includes an electro-hydraulic rod and a lifting plate. There are two sets of symmetrically distributed support seats on the inner bottom of the worktable. The two sets of electro-hydraulic rods are located in the support seats respectively. The output end of the electro-hydraulic rod extends into the opening and is connected to the lifting plate. The lifting plate is driven to move vertically relative to the worktable by the lifting of the electro-hydraulic rod.

[0012] In one embodiment, threaded rods are rotatably mounted on the inner walls of both sides of the fixed plate, and fixed blocks are threaded onto the threaded rods. The paint sprayer is mounted at the bottom of the fixed blocks and above the worktable and clamping assembly. A servo motor is fixedly mounted on the outer wall of one side of the fixed plate. The output shaft of the servo motor extends into the interior of the fixed plate and is fixedly connected to the threaded rods. By controlling the servo motor to rotate the threaded adjustment shaft, the fixed blocks can move laterally within the two sets of fixed plates, thereby driving the paint sprayer to move synchronously.

[0013] In one embodiment, a first drive component is fixedly mounted on a threaded adjusting shaft located outside the top plate.

[0014] In one embodiment, a second driving member is installed on one outer wall of the two fixed plates, and the output end of the second driving member is fixedly connected to the worm gear component via a coupling.

[0015] In one embodiment, both the slot and the mounting block are configured as a cross-shaped structure.

[0016] In one embodiment, a control panel is also included. The control panel is mounted on the outer wall of the workbench and is electrically connected to the paint sprayer, servo motor, first drive component, and second drive component.

[0017] The advantages or beneficial effects of the above technical solutions include at least the following:

[0018] This application discloses a fixing device for spray painting fireproof doors and windows. Due to the structural arrangement of the fixing component, lifting component, and clamping component, the combined use of the fixing and clamping components allows for clamping and fixing of the fireproof doors and windows on all four sides, preventing shaking and detachment during spray painting and thus avoiding adverse effects on the painting effect. Furthermore, since the lower part of the top plate has two sets of receiving grooves, and the fixing component includes a threaded adjusting shaft, a sliding block, and an L-shaped limiting block, with the two sets of threaded adjusting shafts rotatably installed in the receiving grooves, rotating the threaded adjusting shafts causes the two sets of sliding blocks to move the L-shaped limiting block. The two sets of receiving slots can move relative to each other, allowing the spacing of the L-shaped limiting blocks to change synchronously. This adjustable function effectively fixes doors and windows of different sizes and shapes, greatly improving the applicability of the fixing device. Simultaneously, the lifting components provide support for the bottom of the fireproof doors and windows, reducing the labor intensity of operators and ensuring the stability of the fireproof doors and windows during painting operations. This facilitates the clamping of fireproof doors and windows, enhancing the overall use of the fixing device, improving its painting efficiency, and increasing the production efficiency of fireproof doors and windows.

[0040] Reference Figures 1-7 A fixing device for spraying fireproof doors and windows includes a workbench 1, a fixing component 2, a lifting component 3, a clamping component 4, and a spray gun 5. Fixing plates 11 are provided on both sides above the workbench 1, and a top plate 12 is fixedly connected between the two fixing plates 11. Two sets of clamping components 4 are provided and are installed on the two sets of fixing plates 11. The fixing component 2, the clamping component 4, and the spray gun 5 are all located above the workbench 1. The fixing component 2 and the clamping component 4 are arranged in an orthogonal direction, and the clamping component 4 is located between the spray gun 5 and the workbench 1.

[0041] Two sets of lifting components 3 are symmetrically distributed on the inner bottom of the workbench 1. The workbench 1 has an opening 13 located above the two sets of lifting components 3. The lower part of the top plate 12 is provided with a moving groove 121. The two sides of the top plate 12 are provided with through holes 122 communicating with the moving groove 121. A partition block 123 is provided in the middle of the moving groove 121. Both ends of the partition block 123 are provided with limiting grooves 1231. A screw bearing seat 12311 is provided in the limiting groove 1231. The partition block 123 forms two sets of spaced receiving grooves 124 in the moving groove 121. Two sets of fixing components 2 are provided and are located in the two sets of receiving grooves 124 respectively. By setting two sets of receiving grooves 124, the two sets of fixing components 2 can be fixed separately, which improves the practicality of this utility device.

[0042] The fixing component 2 includes a threaded adjusting shaft 21, a sliding block 22, and an L-shaped limiting block 23. Two sets of threaded adjusting shafts 21 are rotatably installed in the receiving groove 124. One end of the threaded adjusting shaft 21 is installed on the lead screw bearing seat 12311, and the other end extends through the through hole 122 to the outside of the top plate 12 and is equipped with a first driving member 211. The sliding block 22 is movably connected to the threaded adjusting shaft 21 and connected to the L-shaped limiting block 23. The first driving member 211 drives the threaded adjusting shaft 21 to rotate, so that the sliding block 22 can move relative to each other in the receiving groove 124, thereby driving the synchronous movement of the L-shaped limiting block 23 and realizing the adjustment of the distance between the L-shaped limiting blocks 23. It can effectively fix fire doors and windows of different sizes and shapes, and greatly improve the production efficiency of fire door and window painting.

[0043] The lower end of the sliding block 22 is provided with a fitting port 221, and the L-shaped limiting block 23 is provided with a connecting protrusion 231. Through the fastening connection between the connecting protrusion 231 and the fitting port 221, the L-shaped limiting block 23 can be installed or removed from the sliding block 22, realizing quick and convenient replacement of the L-shaped limiting block 23. This prevents the need to disassemble the entire fixing component 2 when the L-shaped limiting block 23 wears out after long-term use. It is convenient and quick to use, reduces the labor burden of operators, and further improves production efficiency.

[0044] The clamping assembly 4 includes a worm gear component 41, a lead screw 42, a mounting plate 43, and an electric gripper 44. The electric gripper 44 is movably mounted on the mounting plate 43. The lead screw 42 is rotatably mounted on the fixed plate 11 and connected to the worm gear component 41. A second drive component 112 is mounted on one outer wall of the two fixed plates 11. The output end of the second drive component 112 is fixedly connected to the worm gear component 41 through a coupling. The second drive component 112 controls the worm gear component 41 to drive the lead screw 42 to rotate, so that the two sets of electric grippers 44 can move closer or further apart, realizing the adjustment of the distance between the clamping assemblies 4. This can effectively fix fireproof doors and windows of different thicknesses and sizes, and improve the production efficiency of fireproof door and window painting.

[0045] Based on the above structure, due to the structural arrangement of the fixing component 2, lifting component 3, and clamping component 4, the fireproof door and window can be clamped and fixed simultaneously on all four sides through the combined use of the fixing component 2 and clamping component 4. This achieves stable fixation of the fireproof door and window, ensuring that it will not shake during the painting process, thus preventing uneven painting and affecting product quality. Furthermore, since the lower part of the top plate 12 is provided with a moving groove 121, and a partition block 123 is provided in the middle of the moving groove 121, the partition block 123 forms two sets of spaced receiving grooves 124 in the moving groove 121. The fixing component 2 includes a threaded adjusting shaft 21, a sliding block 22, and an L-shaped limiting block 23. The two sets of threaded adjusting shafts 21 are rotated and installed respectively. Installed in the receiving groove 124, the two sets of sliding blocks 22 drive the L-shaped limiting blocks 23 to move relative to each other in the two sets of receiving grooves 124 by rotating the threaded adjusting shaft 21, thereby adjusting the distance between the L-shaped limiting blocks 23. It has the function of adjustment and can effectively fix fire doors and windows of different sizes and shapes, improving the applicability of the fixing device. At the same time, with the cooperation of the lifting component 3, the bottom of the fire doors and windows can be supported, which can reduce the labor intensity of the operators and ensure the stability of the fire doors and windows during the painting operation, thereby facilitating the clamping of the fire doors and windows, improving the use of the entire fixing device, improving the painting efficiency of the fixing device, and improving the production efficiency of fire doors and windows.

[0046] Furthermore, since the sliding block 22 has a fitting opening 221 at its lower end and the L-shaped limiting block 23 has a connecting protrusion 231, the L-shaped limiting block 23 can be installed or removed from the sliding block 22 through the snap-fit ​​connection between the connecting protrusion 231 and the fitting opening 221. This allows for quick and convenient disassembly of the L-shaped limiting block 23, eliminating the need for operators to disassemble the L-shaped limiting block 23. Additionally, replacing different L-shaped limiting blocks 23 can accommodate fire doors and windows of different sizes and shapes, providing convenient and quick fixation for fire doors and windows of various shapes. This reduces the workload of operators and further improves production efficiency, solving the problems of unstable fixing, poor versatility, and cumbersome operation of existing fixing devices. It achieves stable fixing of fire doors and windows, adapts to various sizes and shapes of doors and windows, and is easy to operate, thus improving production efficiency.

[0047] In one embodiment, reference is made to Figures 1-6 The clamping assembly 4 also includes a rotary cylinder 45, which is located between the mounting plate 43 and the electric gripper 44. One side of the rotary cylinder 45 is connected to the mounting plate 43, and the electric gripper 44 is movably mounted on the other side of the rotary cylinder 45. The bottom of the electric gripper 44 is provided with a slot 441, and the rotary cylinder 45 is provided with a mounting block 451. Through the cooperation of the rotary cylinder 45 and the electric gripper 44, when one side is painted, the paint sprayer 5 is stopped, the fixing assembly 2 is opened, and the lifting assembly 3 is lowered. Through the cooperation of the rotary cylinder 45 and the electric gripper 44, the fireproof door and window on the clamping assembly 4 are flipped. After flipping to the other side, the fixing assembly 2 is fixed, and the lifting assembly 3 is raised to support and then the painting operation is carried out again. It can achieve the flipping of the fireproof door and window while ensuring stability. After flipping, it is firmly fixed. It has the function of flipping the fireproof door and window without disassembly, reducing the labor intensity of the operator, improving the painting efficiency of the device, and indirectly improving the practicality of the fixing device.

[0048] The electric gripper 44 can be installed or removed from the rotary cylinder 45 through the snap-fit ​​connection between the slot 441 and the mounting block 451, making it quick and convenient to replace the electric gripper 44. This eliminates the need for the operator to replace the electric gripper 44. At the same time, replacing the electric gripper 44 with different power and width can adapt to fire doors and windows of different sizes and shapes, and fix fire doors and windows of different thicknesses. It is convenient and quick to use, reduces the workload of operators, and further improves production efficiency.

[0049] In one embodiment, reference is made to Figures 1-4The lifting assembly 3 includes an electro-hydraulic rod 31 and a lifting plate 32. Two sets of symmetrically distributed support seats 14 are located on the inner bottom of the workbench 1. The two sets of electro-hydraulic rods 31 are located within the support seats 14. The output end of the electro-hydraulic rod 31 extends into the opening 13 and connects to the lifting plate 32. The lifting of the electro-hydraulic rod 31 drives the lifting plate 32 to move vertically relative to it, ensuring that fire doors and windows can be clamped. This improves the automation level of the device, reduces the workload of operators, and further improves the quality and efficiency of the painting process. In this technical solution, the electro-hydraulic rod 31 enhances the convenience of lifting fire doors and windows.

[0050] In one embodiment, reference is made to Figures 1-5 and Figure 7 Threaded rods 111 are rotatably mounted on the inner walls of both sides of the fixed plate 11. Fixed blocks 6 are threaded onto the threaded rods 111. The paint sprayer 5 is mounted at the bottom of the fixed blocks 6 and above the worktable 1 and the clamping assembly 4. A servo motor 7 is fixedly mounted on the outer wall of one side of the fixed plate 11. The output shaft of the servo motor 7 extends into the interior of the fixed plate 11 and is fixedly connected to the threaded rods 111. By controlling the servo motor 7 to rotate the threaded adjustment shaft 21, the fixed blocks 6 can move laterally within the two sets of fixed plates 11, thereby driving the paint sprayer 5 to move synchronously. This enables uniform and efficient painting of various parts of fire doors and windows, reducing manpower and time consumption and improving production efficiency.

[0051] In one embodiment, reference is made to Figures 1-6 Both the slot 441 and the mounting block 451 are designed with a cross-shaped structure. The cross-shaped structure is used for snap-fit ​​connection. After snapping in, it is not easy to shift, so it is not easy to fall off during the painting process, and it is easier to limit and stabilize.

[0052] In one embodiment, reference is made to Figures 1-3 It also includes a control panel 8, which is installed on the outer wall of the workbench 1. The control panel 8 is electrically connected to the paint sprayer 5, the servo motor 7, the first drive component 211 and the second drive component 112. The control panel 8 can be implemented by simple programming by those skilled in the art and is common knowledge in the art. It is only used and not modified, so the control method and circuit connection will not be described in detail.
