Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment manufacturing, and specifically to a power distribution equipment housing printing device. Background Technology

[0002] In the field of power equipment manufacturing, the markings on the casings of power distribution equipment are crucial. For example, hazard signs warn operators of potential dangers during the use, maintenance, and repair of power distribution equipment. In cases of electrical hazard, conspicuous colors and specific graphic symbols are typically used to draw attention and remind operators to take appropriate protective measures. Among these, screen printing, with its significant advantage of achieving clear and durable graphic printing effects, has become a key technology in the surface printing process for power distribution equipment casings. The screen printing machine, as the core equipment for performing screen printing operations, operates based on the special structural characteristics of the screen printing plate. Specifically, the mesh openings in the graphic areas of the screen printing plate allow ink to pass through, while the mesh openings in the non-graphic areas do not. During actual printing, ink is applied to one end of the screen printing plate, and then, with the help of a squeegee, the ink is forced from the mesh openings in the graphic areas onto the surface of the power distribution equipment casing, thus completing the printing process.

[0003] However, in current printing production practices for power distribution equipment housings, manual screen printing still dominates. This traditional method, however, exposes several significant drawbacks that urgently need to be addressed: High labor intensity: Operators must exert considerable physical strength continuously while manually pushing the screen printing machine, leading to fatigue and impacting work efficiency and employee health over extended periods; Low production efficiency: The relatively slow pace of manual operation makes it difficult to achieve continuous and efficient production. Compared to automated production, its output per unit time is lower, failing to meet the demands of large-scale production; Unstable printing quality: Numerous factors can negatively affect printing quality during manual screen printing. Firstly, the varying skill levels of operators, with differences in their control over squeegee pressure and speed, make it difficult to ensure consistency even when the same operator performs the operation at different times. This can result in blurry prints, uneven edges, and inconsistent colors, failing to meet the stringent printing quality requirements for power distribution equipment housings.

[0004] In view of the aforementioned prominent problems of manual screen printing, developing a printing device for power distribution equipment housings that can replace manual screen printing is of great practical significance for improving production efficiency and ensuring stable printing quality. Summary of the Invention

[0005] To address the problems of high labor intensity, low production efficiency, and unstable print quality in the current printing production of power distribution equipment housings, this utility model proposes a printing device for power distribution equipment housings. A belt conveyor can continuously transport the power distribution equipment housings, while the lifting mechanism and screen printing mechanism can accurately complete the printing operation. The actions between various components are closely coordinated, significantly increasing the output per unit time compared to manual operation, thus meeting the needs of large-scale production. Pneumatic components such as cylinders one, two, and three enable precise stroke control, ensuring stable and consistent movement of the ink return squeegee and ink scraper during the printing process. Simultaneously, auxiliary components such as guide rods and sensors ensure the accurate positioning of the power distribution equipment housings during transport and printing, resulting in clear printed patterns, neat edges, and uniform color, meeting the stringent requirements for print quality in power distribution equipment housings.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A printing device for power distribution equipment housings includes a frame, a worktable, and a belt conveyor. A lifting mechanism is mounted on the frame, and a screen printing mechanism is mounted on the lifting mechanism. The screen printing mechanism includes a first moving component that moves horizontally and a squeegee mechanism mounted on the first moving component. The squeegee mechanism includes a second moving component and a third moving component that move vertically. A return ink squeegee is connected to the bottom of the second moving component, and a squeegee is connected to the bottom of the third moving component. A screen printing stencil is mounted on the first moving component below the squeegee mechanism. This device transports the power distribution equipment housing via a belt conveyor mounted on the frame. The lifting mechanism drives the screen printing mechanism to move up and down. The first moving component in the screen printing mechanism enables the horizontal movement of the squeegee mechanism, while the second and third moving components control the vertical movement of the return ink squeegee and the squeegee, respectively, working in conjunction with the screen printing stencil to complete the printing operation on the power distribution equipment housing.

[0008] Furthermore, the lifting mechanism includes a cylinder fixed to the bottom of the frame. A frame is mounted on the top of the telescopic rod of the cylinder, and two sets of sliding rods are mounted on the top of the frame. A seat sleeve is provided on the worktable for the sliding rods to pass through. Each set of sliding rods consists of two rods symmetrically distributed on both sides of the belt conveyor. A support plate is mounted on the top of each set of two sliding rods, and the moving component is mounted on the support plate. The support plate provides a stable bearing platform for the moving component. The telescopic movement of the cylinder enables the entire frame to move up and down. Furthermore, during the lifting and lowering process driven by the cylinder, the sliding rods slide up and down along the seat sleeve on the worktable, preventing the screen printing mechanism from swaying or shifting during the lifting and lowering process.

[0009] Furthermore, the first moving component includes guide rails respectively mounted on two support plates, each guide rail having a slider slidably mounted on it. The two sliders are connected by a mounting base plate, and one of the sliders is connected to a synchronous belt mechanism via a connecting plate. The cooperation between the slider and the guide rail provides a stable motion track for the first moving component; through the mounting base plate, the scraper mechanism can move horizontally synchronously with the movement of the slider on the guide rail. When the synchronous belt mechanism moves, it drives the connecting plate and the slider connected to it to move on the guide rail.

[0010] Furthermore, the synchronous belt mechanism includes a motor, a reducer, and pulleys rotatably mounted at both ends of the support plate. The two pulleys are connected by a synchronous belt body, which is fixedly connected to a connecting plate. The reducer is fixed on the support plate, and the output end of the motor is connected to the input end of the reducer. The output end of the reducer is connected to one of the pulleys.

[0011] Furthermore, the second moving component includes a second cylinder, and the ink return scraper is disposed at the bottom of the telescopic rod of the second cylinder. The third moving component includes a third cylinder, and the scraper is disposed at the bottom of the telescopic rod of the third cylinder. The cylinder bodies of the second and third cylinders are respectively fixed on both sides of the mounting base plate. The second and third cylinders are independent of each other, and the ink return scraper and the scraper can move independently in the vertical direction. Independent motion control allows the ink return and scraping operations to be adjusted according to actual printing needs.

[0012] Furthermore, both ends of the screen printing stencil are secured with fixing frames, and tightening bolts are threaded onto the fixing frames. A bracket is provided at the bottom of the support plate, and an adjusting rod is slidably mounted on the bracket. One end of the adjusting rod is connected to the fixing frame. The tightening bolts are bolts with handles. The fixing frames secure the two ends of the screen printing stencil, and the tightening bolts fix the screen printing stencil within the two fixing frames. This structural design makes disassembly and installation more convenient when it is necessary to replace screen printing stencils with different patterns or specifications.

[0013] Furthermore, the belt conveyor is equipped with guide rods, sensors, and cylinder four. Two guide rods are symmetrically distributed above the belt conveyor, and cylinder four is located on the same side of one of the guide rods. The sensors and cylinder four are both positioned above the guide rods. The guide rods ensure that the power distribution equipment housing moves stably in a predetermined direction; the sensors detect the position of the power distribution equipment housing; and the extended cylinder four effectively positions the power distribution equipment housing, stably fixing it at the printed position.

[0014] Furthermore, wheels and feet are provided at the four corners of the bottom of the frame. The wheels allow the entire device to move easily on the ground; the feet provide stable support for the device on the ground after it has been moved to the designated position.

[0015] The beneficial effects of this utility model through the above technical solution are as follows:

[0016] The power distribution equipment housing printing device provided by this utility model transports the power distribution equipment housing via a belt conveyor mounted on a frame. A lifting mechanism drives the screen printing mechanism to move up and down. Moving component one in the screen printing mechanism enables the horizontal movement of the squeegee mechanism, while moving components two and three control the vertical movement of the ink return squeegee and the ink scraper, respectively, working in conjunction with the screen printing stencil to complete the printing operation on the power distribution equipment housing. Simultaneously, the device is also equipped with guide rods and sensor auxiliary components to ensure the accuracy of the power distribution equipment housing transport and printing.

[0017] In this device, the housing of the power distribution equipment is placed on a belt conveyor and moves forward under the drive of the conveyor. At this time, two guide rods symmetrically distributed above the belt conveyor form a channel, allowing the housing to be transported within the channel. Cylinder 1 is fixed to the bottom of the frame, and its telescopic rod has a frame at the top. The telescopic movement of cylinder 1 drives the entire frame to move up and down. The screen printing mechanism is set on the frame of the lifting mechanism, and the moving component 1 is responsible for the horizontal movement of the scraper mechanism. Two support plates are respectively equipped with guide rails, and sliders are slidably mounted on the guide rails. The two sliders are connected by a mounting base plate. One of the sliders is connected to the timing belt mechanism via a connecting plate. The timing belt drives the slider to slide on the guide rail through the connecting plate, realizing the horizontal movement of the scraper mechanism. The scraper mechanism has moving components 2 and 3, and cylinders 2 and 3 are both adjustable-stroke cylinders, with the cylinder bodies fixed on both sides of the mounting base plate. The return ink scraper is located at the bottom of the extension rod of cylinder two, and the ink scraper is located at the bottom of the extension rod of cylinder three. Both can be independently controlled to move vertically. When the housing is transported to the designated printing position, the lifting mechanism has adjusted the screen printing mechanism to the appropriate height, and the moving component one moves the scraper mechanism to the starting position. First, cylinder two drives the return ink scraper to apply ink, and then drives it to move upward. Next, cylinder three drives the ink scraper to move downward, while the moving component one drives the scraper mechanism to move horizontally to complete the printing. The belt conveyor is equipped with a laser sensor and a threaded cylinder four. The sensor detects the housing position feedback signal, and the control system controls cylinder four to extend and position the housing. After printing, cylinder four retracts to release the positioning, and the operation is repeated to achieve efficient printing.

[0018] The device features a belt conveyor that continuously transports the power distribution equipment housing, while the lifting and screen printing mechanisms enable rapid and accurate printing operations. The seamless coordination between components significantly shortens the printing time for individual housings, achieving a continuous and efficient production mode. Compared to manual operation, the output per unit time is significantly increased, meeting the demands of large-scale production and effectively improving enterprise productivity. Simultaneously, pneumatic components such as cylinders one, two, and three achieve precise pressure and stroke control, ensuring stable and consistent movement of the ink return squeegee and ink scraper during the printing process. Furthermore, auxiliary components such as guide rods and sensors ensure the accurate positioning of the power distribution equipment housing during transport and printing, resulting in clear printed patterns, neat edges, and uniform color. This effectively solves the problem of inconsistent printing quality caused by varying operator skill levels during manual screen printing, meeting the stringent printing quality requirements of the power distribution equipment housing.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] like Figures 1-5 As shown, this embodiment provides a power distribution equipment housing printing device. The power distribution equipment housing printing device includes a frame 1, a workbench 2, and a belt conveyor 3. A lifting mechanism is provided on the frame 1, and a screen printing mechanism is provided on the lifting mechanism. The screen printing mechanism includes a moving component one that moves in the horizontal direction and a squeegee mechanism provided on the moving component one. The squeegee mechanism includes a moving component two and a moving component three that move in the vertical direction. A return ink squeegee 4 is connected to the bottom of the moving component two, and an ink scraper 5 is connected to the bottom of the moving component three. A screen printing stencil 6 is provided on the moving component one below the squeegee mechanism.

[0028] The power distribution equipment housing printing device provided by this utility model transports the power distribution equipment housing via a belt conveyor 3 mounted on a frame 1. A lifting mechanism drives the screen printing mechanism to move up and down. Moving component one in the screen printing mechanism enables the horizontal movement of the squeegee mechanism, while moving components two and three control the vertical movement of the ink return squeegee 4 and the ink scraper 5, respectively, working in conjunction with the screen printing stencil 6 to complete the printing operation on the power distribution equipment housing. Simultaneously, the device is also equipped with guide rods 25 and sensors 26 as auxiliary components to ensure the accuracy of the power distribution equipment housing transport and printing.

[0029] In this embodiment, the lifting mechanism includes a cylinder 7 fixed to the bottom of the frame 1. A frame 8 is mounted on the top of the telescopic rod of the cylinder 7. Two sets of sliding rods 9 are mounted on the top of the frame 8. A seat sleeve for the sliding rods 9 to pass through is provided on the worktable 2. Each set of two sliding rods 9 is symmetrically distributed on both sides of the belt conveyor 3. A support plate 10 is mounted on the top of each set of two sliding rods 9. The moving component is mounted on the support plate 10. The support plate 10 provides a stable bearing platform for the moving component. The support plate 10 moves synchronously with the screen printing mechanism, ensuring that the squeegee mechanism can accurately reach the designated printing position above the power distribution equipment housing.

[0030] In this invention, cylinder 7 is fixed to the bottom of the frame 1, and a frame 8 is mounted on the top of its telescopic rod. The telescopic movement of cylinder 7 drives the entire frame 8 to move up and down. This design provides a reliable lifting power source for the screen printing mechanism, allowing it to flexibly adjust its height according to the height of different power distribution equipment housings and printing process requirements. This ensures a suitable distance between the screen printing mechanism and the housing, creating a foundation for accurate printing. Furthermore, during the lifting and lowering process of the frame 8 driven by cylinder 7, the sliding rod 9 slides up and down along the seat sleeve on the worktable 2, preventing the screen printing mechanism from swaying or shifting during lifting, thus ensuring the stability and accuracy of the lifting process.

[0031] Please refer to this again. Figure 3 The moving component includes guide rails 11 respectively disposed on two support plates 10, and a slider 12 is slidably disposed on each guide rail 11. The two sliders 12 are connected by a mounting base plate 13, and one of the sliders 12 is connected to a synchronous belt mechanism through a connecting plate 14.

[0032] The cooperation between slider 12 and guide rail 11 provides a stable motion track for the moving component, and the two sliders 12 are connected by mounting base 13, integrating the dispersed sliders 12 into a whole. Mounting base 13 not only connects the sliders 12 but also provides a stable mounting platform for the scraper mechanism. Through mounting base 13, the scraper mechanism can move horizontally synchronously with the movement of slider 12 on guide rail 11. When the timing belt mechanism moves, it drives connecting plate 14 and the connected slider 12 to move on guide rail 11.

[0033] Specifically, the synchronous belt mechanism includes a motor 15, a reducer 16, and pulleys 17 rotatably mounted at both ends of the support plate 10. The two pulleys 17 are connected by a synchronous belt body 18, which is fixedly connected to a connecting plate 14. The reducer 16 is fixed to the support plate 10. The output end of the motor 15 is connected to the input end of the reducer 16, and the output end of the reducer 16 is connected to one of the pulleys 17. When the synchronous belt body 18 moves under the drive of the pulleys 17, it drives the slider 12 to slide on the guide rail 11 through the connecting plate 14. The connecting plate 14 converts the linear motion of the synchronous belt body 18 into the horizontal motion of the slider 12.

[0034] Please refer to this again. Figure 4 The second moving component includes a second cylinder 19, and the ink return scraper 4 is disposed at the bottom of the telescopic rod of the second cylinder 19. The third moving component includes a third cylinder 20, and the ink scraper 5 is disposed at the bottom of the telescopic rod of the third cylinder 20. The cylinder bodies of the second cylinder 19 and the third cylinder 20 are respectively fixed on both sides of the mounting base plate 13.

[0035] It should be noted that both cylinder 19 and cylinder 20 are adjustable-stroke cylinders; cylinder 19 and cylinder 20 are independent of each other, and the ink return squeegee 4 and the squeegee 5 can move independently in the vertical direction. Independent motion control allows the ink return and squeegee operations to be adjusted according to actual printing needs, avoiding mutual interference between the two operations. During the printing process, ink return and squeegee are two different operation steps. The ink return squeegee 4 is mainly responsible for evenly applying ink to the screen printing plate 6, while the squeegee 5 is responsible for printing the ink through the screen printing plate 6 onto the electrical equipment housing.

[0036] In this embodiment, both ends of the screen printing plate 6 are fastened with a fixing frame 21, and a clamping bolt 22 is threaded onto the fixing frame 21. A bracket 23 is provided at the bottom of the support plate 10, and an adjusting rod 24 is slidably provided on the bracket 23. One end of the adjusting rod 24 is connected to the fixing frame 21.

[0037] The clamping bolt 22 is a bolt with a handle. It clamps the two ends of the screen printing stencil 6 through the fixing frame 21 and fixes the screen printing stencil 6 within the two fixing frames 21. When it is necessary to replace the screen printing stencil 6 with a different pattern or specification, this structural design makes the disassembly and installation process more convenient. The operator only needs to loosen the clamping bolt 22 to remove the screen printing stencil 6 from the fixing frame 21, then replace it with a new screen printing stencil 6 and re-clamp it, and then tighten the clamping bolt 22 to complete the installation. The sliding adjustment function of the adjusting rod 24 on the bracket 23 can accommodate screen printing stencils 6 of different sizes. By adjusting the position of the adjusting rod 24, it can be ensured that the fixing frame 21 can accurately fix screen printing stencils 6 of different sizes, improving the versatility and flexibility of the equipment.

[0038] Please refer to this again. Figure 5 The belt conveyor 3 is equipped with guide rods 25, sensors 26 and cylinders 27. There are two guide rods 25, which are symmetrically distributed above the belt conveyor 3. The cylinders 27 are located on the same side of one of the guide rods 25. The positions of the sensors 26 and cylinders 27 are both higher than the positions of the guide rods 25.

[0039] Two guide rods 25 are spaced apart to form a channel for the power distribution equipment housing to pass through. It is worth noting that the spacing between the two guide rods 25 is adjustable to accommodate different models of power distribution equipment housings. Specifically, the guide rods 25 provide a clear guiding path for the power distribution equipment housing on the belt conveyor 3, effectively preventing deviation during transport and ensuring stable forward movement along a predetermined direction, laying the foundation for accurate subsequent printing operations. Sensor 26 is a laser sensor capable of detecting the position of the power distribution equipment housing. Cylinder 27 is a threaded cylinder; when extended, it effectively positions the power distribution equipment housing, stably fixing it in the printing position and preventing movement during printing, thus effectively improving printing accuracy and stability.

[0040] In addition, wheels 28 and feet 29 are provided at the four corners of the bottom of the frame 1. The wheels 28 at the bottom of the frame 1 allow the entire device to move easily on the ground; the feet 29 are used to stably support the device on the ground after it has been moved to the designated position.

[0041] The working principle of this utility model is as follows:

[0042] The power distribution equipment housing is placed on the belt conveyor 3 and moves forward under the drive of the belt conveyor 3; during this process, a channel is formed between two guide rods 25 symmetrically distributed above the belt conveyor 3, and the power distribution equipment housing is conveyed forward in the channel.

[0043] The lifting mechanism's cylinder 7 is fixed to the bottom of the frame 1, and a frame 8 is mounted on the top of its telescopic rod. The telescopic movement of cylinder 7 drives the entire frame 8 to move up and down. Two sets of sliding rods 9 are mounted on the top of the frame 8, and a seat sleeve is provided on the worktable 2 for the sliding rods 9 to pass through. During the lifting and lowering process of the frame 8, the sliding rods 9 slide up and down along the seat sleeve on the worktable 2.

[0044] The screen printing mechanism is mounted on the frame 8 of the lifting mechanism, with the first moving component responsible for the horizontal movement of the scraper mechanism. Guide rails 11 are respectively mounted on the two support plates 10 of the first moving component, and a slider 12 is slidably mounted on each guide rail 11. The two sliders 12 are connected by a mounting base plate 13. One of the sliders 12 is connected to a synchronous belt mechanism via a connecting plate 14. The motor 15 of the synchronous belt mechanism outputs power, which, after being reduced in speed and torque by a reducer 16, drives the pulley 17 to rotate, thereby moving the synchronous belt body 18. The synchronous belt body 18, through the connecting plate 14, drives the slider 12 to slide on the guide rail 11, thus realizing the horizontal movement of the scraper mechanism.

[0045] When the power distribution equipment housing is transported to the designated printing position, the lifting mechanism adjusts the screen printing mechanism to the appropriate height. Moving component one moves the squeegee mechanism to the starting position. First, cylinder two 19 drives the ink return squeegee 4 downwards, evenly applying ink to the screen printing stencil 6. After completing the ink return operation, cylinder two 19 drives the ink return squeegee 4 upwards. Next, cylinder three 20 drives the squeegee 5 downwards, while moving component one moves the squeegee mechanism horizontally. The squeegee 5 then prints ink through the screen printing stencil 6 onto the power distribution equipment housing, completing one printing operation.

[0046] A sensor 26 and a cylinder 27 are installed on the belt conveyor 3. The sensor 26 is a laser sensor, and the cylinder 27 is a threaded cylinder. Both the sensor 26 and the cylinder 27 are positioned above the guide rod 25. When the power distribution equipment housing is conveyed to the position of the sensor 26, the sensor 26 detects the position information of the power distribution equipment housing and feeds the signal back to the control system. Based on the signal fed back by the sensor 26, the control system controls the cylinder 27 to extend. After the cylinder 27 extends, it effectively positions the power distribution equipment housing and stably fixes the power distribution equipment housing at the printing position.

[0047] After a printing operation is completed, cylinder 3 20 drives the squeegee 5 to move upward, and cylinder 4 27 retracts, releasing the positioning of the power distribution equipment housing; belt conveyor 3 continues to operate, transporting the printed power distribution equipment housing away, and at the same time transporting the next power distribution equipment housing to be printed to the designated position.

[0048] By repeating the above steps, the printing work for the next power distribution equipment casing can be carried out, which is highly efficient.

[0049] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
