Description

Technical Field

[0001] This utility model relates to the field of metal door manufacturing technology, and in particular to a metal door surface treatment device. Background Technology

[0002] Surface treatment is crucial in the production and processing of metal doors. Traditional metal door surface treatment equipment suffers from numerous problems in actual operation. Firstly, different specifications of metal doors require different fixing and conveying structures, which traditional equipment often struggles to adjust flexibly, resulting in low processing efficiency for metal doors of diverse sizes. For example, when dealing with metal doors with significant width variations, conventional equipment cannot quickly and easily change the fixing spacing, leading to difficulties in feeding and potential misalignment during conveying, affecting subsequent surface treatment results. Secondly, if debris and dust generated during processing are not cleaned up promptly, they will not only interfere with subsequent processes (e.g., entering threaded connections and hindering the normal operation of threaded rods), but also pollute the working environment and endanger the health of operators.

[0003] Therefore, we propose a surface treatment device for metal doors. Utility Model Content

[0004] The main purpose of this utility model is to provide a metal door surface treatment device to prevent problems such as low processing efficiency, difficulty in feeding, and conveying deviation affecting the processing effect of metal doors of different specifications caused by the difficulty in flexibly adjusting the fixing and conveying structure of traditional devices, as well as process interference, equipment operation obstruction, and threats to the environment and personnel health caused by untimely cleaning of debris and dust. In order to improve the efficiency, quality, equipment operation stability and working environment safety of metal door surface treatment, it can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A surface treatment device for metal doors includes a treatment table. First threaded rods are rotatably connected to the inner walls of both ends of a groove at the front of the treatment table. A first motor is fixedly installed on the outer wall of one end of the treatment table. The output shaft of the first motor is fixedly connected to one end of the first threaded rod. Two sets of opposing output threaded grooves are provided on the outer side of the first threaded rod. A movable table is threadedly connected to the outer side of the threaded grooves. Annular sleeves are fixedly connected to both sides of the movable table and to the outside of the first threaded rods. An annular cleaning brush for cleaning the first threaded rods is fixedly installed on the inner side of the annular sleeves. Two symmetrical first sliding rods are fixedly connected to the inner walls of both ends of the groove at the front of the treatment table. Two first through holes are provided on the movable table. The first sliding rods pass through the first through holes and are slidably engaged with the first through holes. Multiple wheel frames are equidistantly arranged at the top of the movable table. Rotary wheels are rotatably connected to the inner side of each wheel frame. A side frame is fixedly connected to the top of the movable table. Rotary rollers are rotatably connected to the top and bottom of the side frame, and multiple rotating rollers are equidistantly arranged.

[0007] By adopting the above technical solution, the metal door is placed on the rotating wheels of two sets of moving platforms. The first motor is started, and the first motor drives the first threaded rod to rotate. Since the first threaded rod has two sets of opposite output threaded grooves on its outer side, the two moving platforms will move in opposite or opposite directions along the first sliding rod under the action of the thread, thereby adapting to metal doors of different widths. During the movement, the rotating wheels can rotate with the movement of the metal door, reducing the friction between the metal door and the moving platform and facilitating the transport of the metal door. At the same time, the rotating rollers on the side frame limit the metal door from both sides to prevent the metal door from shifting during the movement. The annular cleaning brush on the inner side of the annular sleeve will always be in contact with the first threaded rod when the moving platform moves, cleaning the debris and dust on the surface of the first threaded rod and avoiding impurities from affecting the smoothness of the threaded connection.

[0008] Furthermore, two symmetrical supports are fixedly connected to the top of the processing table, and a second threaded rod is rotatably connected between the two supports. A movable block is threadedly connected to the outer side of the second threaded rod. A second motor is fixedly installed on one side of the outer wall of one of the supports, and the output shaft of the second motor is fixedly connected to one end of the second threaded rod.

[0009] By adopting the above technical solution, when the grinding position needs to be adjusted, the second motor is started, and the second motor drives the second threaded rod to rotate between the two brackets. Under the action of the thread of the second threaded rod, the movable block will move along the length of the second threaded rod, thereby causing the relevant grinding components installed on the movable block to change position to adapt to the grinding needs of different parts of the metal door.

[0010] Furthermore, a second sliding rod is fixedly connected between the two brackets, and a second through hole is provided on the movable block. The second sliding rod passes through the second through hole, and the second sliding rod is slidably connected to the second through hole.

[0011] By adopting the above technical solution, when the movable block moves under the action of the second motor and the second threaded rod, the second slide rod passes through the second through hole on the movable block, which guides and limits the movement of the movable block, prevents the movable block from rotating or deviating during the movement, ensures that the movable block can move stably and accurately along the set direction, and guarantees the accuracy of the grinding work.

[0012] Furthermore, a cylinder is fixedly installed on the inner wall of the bottom end of the movable block, and the telescopic end of the cylinder passes through the movable block and is fixedly connected to a moving plate. A grinder is fixedly installed on the bottom end of the moving plate.

[0013] By adopting the above technical solution, when the movable block moves to the appropriate position, the cylinder is activated. The extension and retraction end of the cylinder drives the moving plate to move up and down, thereby adjusting the distance between the grinder and the surface of the metal door. When the grinder contacts the surface of the metal door, the grinder can be activated to grind the surface of the metal door. During the grinding process, the movable block can be moved by controlling the second motor to realize the lateral movement of the grinder on the surface of the metal door, thus completing the grinding of different areas of the metal door.

[0014] Furthermore, a fixed base is fixedly connected to the top of the processing table, a fan is fixedly installed on the upper surface of the fixed base, a dust collection hood is installed on the lower surface of the fixed base, the fan is connected to the dust collection hood, and an air outlet pipe is connected to the exhaust end of the fan.

[0015] By adopting the above technical solution, when the grinder produces debris and dust while grinding the surface of the metal door, the fan is started. The fan generates negative pressure through the dust collection hood, which sucks the debris and dust generated during the grinding process into the dust collection hood. Then, the debris and dust are discharged through the exhaust pipe from the exhaust end of the fan to the designated collection device, thus avoiding the pollution of the working environment by debris and dust. At the same time, it is also convenient to centrally process and recycle the debris.

[0016] Furthermore, a discharge chute is provided on the fixed base.

[0017] By adopting the above technical solution, after the metal door has completed the grinding and other processing procedures on the processing table, it needs to be removed from the processing table. The discharge slot opened on the fixed base provides a channel for the removal of the metal door. The staff can more easily carry the processed metal door off the processing table through the discharge slot, which improves work efficiency and also avoids damage to the surface of the metal door during the transportation process.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This utility model provides a surface treatment device for metal doors. Through a unique structural design, the metal door is placed on the rotating wheels of two sets of moving tables. The first motor is started, and the first motor drives the first threaded rod to rotate. Since the outer side of the first threaded rod is provided with two sets of opposite output threaded grooves, the two moving tables will move in opposite or opposite directions along the first sliding rod under the action of the thread. It can quickly and accurately adapt to metal doors of different widths. During the movement, the rotating wheels can rotate with the movement of the metal door, which greatly reduces the friction between the metal door and the moving table. This not only facilitates the transportation of the metal door, but also reduces the risk of scratches on the door surface caused by friction. At the same time, the rotating rollers on the side frame limit the metal door from both sides, effectively preventing the metal door from shifting during the movement. This ensures that the metal door maintains a stable position throughout the entire surface treatment process, laying a solid foundation for subsequent precise surface treatment operations and greatly improving the processing efficiency and quality of metal doors of different specifications.

[0020] (2) This utility model discloses a metal door surface treatment device. During the operation of the device, the annular cleaning brush inside the annular sleeve is always in contact with the first threaded rod as the moving platform moves, continuously cleaning the debris and dust on the surface of the first threaded rod. This design avoids impurities affecting the smoothness of the threaded connection, ensuring that the first threaded rod can work stably and efficiently, and reducing equipment failures and maintenance frequency caused by impurity accumulation. Compared with traditional devices, there is no need for frequent manual cleaning of the threaded rod, reducing labor intensity and improving the continuity and stability of equipment operation. Moreover, this automated cleaning function is carried out synchronously with the entire metal door processing flow of the device, without taking up extra time, further improving overall production efficiency and ensuring the efficient and stable implementation of metal door surface treatment work.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] To prevent problems caused by the inflexibility of adjusting the fixing and conveying structure in traditional equipment, such as low processing efficiency for metal doors of different specifications, difficulties in feeding, and conveyor deviation affecting processing results, as well as process interference, equipment operation obstruction, and threats to the environment and personnel health caused by untimely cleaning of debris and dust, and to improve the efficiency, quality, equipment operational stability, and safety of the working environment in metal door surface treatment, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a metal door surface treatment device includes a treatment table 1. A first threaded rod 2 is rotatably connected to the inner walls of both ends of a groove at the front of the treatment table 1. A first motor 3 is fixedly installed on the outer wall of one end of the treatment table 1. The output shaft of the first motor 3 is fixedly connected to one end of the first threaded rod 2. Two sets of opposing output threaded grooves are provided on the outer side of the first threaded rod 2. A movable table 4 is threadedly connected to the outer side of the threaded grooves. Annular sleeves 5 are fixedly connected to both sides of the movable table 4 and located outside the first threaded rod 2. A cleaning device for the first threaded rod 2 is fixedly installed on the inner side of the annular sleeves 5. A threaded rod 2 has an annular cleaning brush 6. Two symmetrical first sliding rods 11 are fixedly connected to the inner walls of the two ends of the groove at the front of the treatment table 1. The moving table 4 is provided with two first through holes 12. The first sliding rods 11 pass through the first through holes 12 and are slidably connected to the first through holes 12. Multiple wheel frames 7 are equidistantly arranged at the top of the moving table 4. Rotary wheels 8 are rotatably connected to the inner side of the wheel frames 7. A side frame 9 is fixedly connected to the top of the moving table 4. Rotary rollers 10 are rotatably connected to the top and bottom of the side frame 9, and multiple rotating rollers 10 are equidistantly arranged.

[0028] In use, the metal door is placed on the rotating wheels 8 of the two sets of moving platforms 4, and the first motor 3 is started. The first motor 3 drives the first threaded rod 2 to rotate. Since the first threaded rod 2 has two sets of opposite output threaded grooves on its outer side, the two moving platforms 4 will move in opposite or opposite directions along the first slide rod 11 under the action of the thread, thereby adapting to metal doors of different widths. During the movement, the rotating wheels 8 can rotate with the movement of the metal door, reducing the friction between the metal door and the moving platform 4 and facilitating the transport of the metal door. At the same time, the rotating rollers 10 on the side frame 9 limit the metal door from both sides to prevent the metal door from shifting during the movement. The annular cleaning brush 6 inside the annular sleeve 5 will always be in contact with the first threaded rod 2 when the moving platform 4 moves, cleaning the debris and dust on the surface of the first threaded rod 2 to avoid impurities affecting the smoothness of the threaded connection.

[0029] For example, such as Figure 3 , Figure 4 As shown, the present invention also includes two symmetrical supports 13 fixedly connected to the top of the processing table 1, a second threaded rod 14 rotatably connected between the two supports 13, a movable block 16 threadedly connected to the outer side of the second threaded rod 14, and a second motor 15 fixedly installed on one side of the outer wall of one of the supports 13, the output shaft of the second motor 15 being fixedly connected to one end of the second threaded rod 14.

[0030] When adjusting the grinding position during use, the second motor 15 is activated, which drives the second threaded rod 14 to rotate between the two supports 13. Under the action of the thread of the second threaded rod 14, the movable block 16 moves along the length of the second threaded rod 14, thereby causing the relevant grinding components installed on the movable block 16 to change position to adapt to the grinding needs of different parts of the metal door.

[0031] For example, such as Figure 3 , Figure 4 As shown, the present invention also includes a second sliding rod 17 fixedly connected between the two brackets 13, a second through hole 18 provided on the movable block 16, the second sliding rod 17 passing through the second through hole 18, and the second sliding rod 17 and the second through hole 18 being slidably connected.

[0032] When in use, when the movable block 16 moves under the action of the second motor 15 and the second threaded rod 14, the second slide rod 17 passes through the second through hole 18 on the movable block 16, which guides and limits the movement of the movable block 16, preventing the movable block 16 from rotating or deviating during the movement, ensuring that the movable block 16 can move stably and accurately along the set direction, and ensuring the accuracy of the grinding work.

[0033] For example, such as Figure 4As shown, the present invention also includes a cylinder 19 fixedly installed on the inner wall of the bottom end of the movable block 16, the telescopic end of the cylinder 19 passing through the movable block 16 and fixedly connected to a movable plate 20, and a grinder 21 fixedly installed on the bottom end of the movable plate 20.

[0034] When in use, after the movable block 16 moves to the appropriate position, the cylinder 19 is activated. The telescopic end of the cylinder 19 drives the moving plate 20 to move up and down, thereby adjusting the distance between the grinder 21 and the surface of the metal door. When the grinder 21 contacts the surface of the metal door, the grinder 21 can be activated to grind the surface of the metal door. During the grinding process, the movable block 16 can be moved by controlling the second motor 15 to realize the lateral movement of the grinder 21 on the surface of the metal door, thus completing the grinding of different areas of the metal door.

[0035] For example, such as Figure 1 As shown, the present invention also includes a fixed base 22 fixedly connected to the top of the processing table 1, a fan 23 fixedly installed on the upper surface of the fixed base 22, a dust collection hood 24 installed on the lower surface of the fixed base 22, the fan 23 communicating with the dust collection hood 24, and an air outlet pipe 25 connected to the exhaust end of the fan 23.

[0036] When the grinder 21 grinds the surface of the metal door and generates debris and dust, the fan 23 is started. The fan 23 generates negative pressure through the dust collection hood 24, which draws the debris and dust generated during the grinding process into the dust collection hood 24. Then, the debris and dust are discharged through the exhaust pipe 25 from the exhaust end of the fan 23 to the designated collection device, which avoids the debris and dust from polluting the working environment and also facilitates the centralized processing and recycling of the debris.

[0037] For example, such as Figure 3 As shown, the present invention also includes a discharge groove 26 provided on the fixed base 22.

[0038] When in use, after the metal door has completed the grinding and other processing procedures on the processing table, it needs to be removed from the processing table. The discharge slot 26 opened on the fixed base 22 provides a channel for the removal of the metal door. The staff can use the discharge slot 26 to more conveniently carry the processed metal door off the processing table, which improves work efficiency and also avoids damage to the surface of the metal door during the transportation process.

[0039] It should be noted that this utility model is a surface treatment device for metal doors. The metal door to be treated is placed on the rotating wheels 8 of two sets of moving platforms 4. The first motor 3 is started according to the width of the metal door. The first motor 3 drives the first threaded rod 2 to rotate, so that the two moving platforms 4 move in opposite directions along the first slide rod 11 under the action of the thread to adapt to the width of the metal door. At this time, the rotating rollers 10 on the side frame 9 limit the metal door from both sides. The annular cleaning brush 6 inside the annular sleeve 5 cleans the debris and dust on the surface of the first threaded rod 2 when the moving platforms 4 move. Then, the second motor 15 is started, which drives the second threaded rod 14 to rotate, so that the movable block 16 moves under the guide limit of the second slide rod 17. The metal door is positioned above the area to be polished. After the position of the movable block 16 is determined, the cylinder 19 is activated to move the moving plate 20 up and down to adjust the distance between the polisher 21 and the surface of the metal door. Once the polisher 21 contacts the surface of the metal door, the polisher 21 is activated. At the same time, the second motor 15 is controlled to move the movable block 16, so that the polisher 21 moves laterally on the surface of the metal door to complete the polishing of different areas. During the polishing process, the fan 23 on the fixed base 22 is activated, and the dust collection hood 24 generates negative pressure to suck in the debris and dust, which is then discharged through the air outlet 25 to the designated collection device. After the metal door is polished, it is removed from the processing table 1 through the discharge chute 26 on the fixed base 22.
