Description

Technical Field

[0001] This application relates to the field of wooden furniture, and more particularly to a workbench for painting wooden furniture. Background Technology

[0002] Wooden furniture holds an important position in the furniture market due to its natural texture, environmental friendliness, durability, and aesthetic appeal. Wood itself is susceptible to deformation due to environmental humidity, making painting an essential process in wooden furniture manufacturing. After painting, the paint layer forms a protective film, isolating the wood from the external environment and reducing deformation caused by the absorption or release of moisture, thus extending the furniture's lifespan.

[0003] A typical workbench for painting wooden furniture consists of a spray booth, a workbench, and a positioning structure. The workbench is installed inside the spray booth to provide a platform for painting the furniture. The positioning structure is installed on the upper part of the workbench and supports the wooden furniture, reducing the contact area between the workbench and the furniture. When painting wooden furniture, it needs to be placed on the workbench inside the spray booth for the painting process.

[0004] In the existing technology, due to the diversity of wooden furniture types, the position of the positioning structure on the workbench needs to be adjusted according to the type of furniture during painting. This not only increases the workload of the workers, but also affects the painting efficiency of wooden furniture. Utility Model Content

[0005] In order to facilitate the painting process of different types of wooden furniture and improve the painting efficiency of wooden furniture, this application provides a workbench for painting wooden furniture.

[0006] The technical solution provided in this application for a workbench for spray painting wooden furniture is as follows: A workbench for painting wooden furniture includes a base, a transmission rod mounted on the base, and a positioning platform mounted on the upper end of the transmission rod. Positioning structures for limiting the position of the furniture are respectively installed at both ends of the positioning platform. Each positioning structure includes a support rod and a positioning rod. Connectors for connecting to the positioning platform are fixedly connected to both ends of the support rod. Slide grooves for sliding of the connectors are respectively opened on the lower sides of both ends of the positioning platform. The positioning rod is installed on the upper side of the support rod. The positioning platform is equipped with a drive mechanism for adjusting the positions of the two positioning structures.

[0007] By adopting the above technical solution, firstly, the positioning structure can limit the position of the furniture, keeping it stable during the painting process and avoiding uneven or missed painting due to shaking, thereby improving painting efficiency and quality; secondly, the drive mechanism can adjust the position of the two positioning structures, enabling the workbench to adapt to the painting needs of wooden furniture of different sizes, thus expanding the applicability of the workbench.

[0008] Optionally, the connector includes a connecting rod and a slider, the upper end of the connecting rod is fixedly connected to the support rod, the slider is fixedly connected to the lower end of the connecting rod, and the slider is slidably connected to the inner wall of the groove.

[0009] By adopting the above technical solution, the connection between the support rod and the positioning platform is made more stable through the connecting rod and slider structure of the connector, which can better bear the weight of the furniture and the external force during the painting process, and ensure the stability of the positioning structure; the slider and the slide groove enable the positioning structure to move smoothly when adjusting the position, reducing frictional resistance.

[0010] Optionally, each of the two inner walls of the opposite sides of the slide is rotatably connected with a bidirectional threaded rod, each of the bidirectional threaded rods is threadedly connected to the inner wall of the slider, and two limiting plates are provided between each pair of sliders and are fixedly connected to the outer wall of the bidirectional threaded rod.

[0011] By adopting the above technical solution, the threaded connection between the bidirectional threaded rod and the slider, as well as the fixed connection of the limiting plate, can accurately control the movement distance of the slider, thereby accurately adjusting the position of the positioning structure, ensuring that the furniture can be accurately fixed in the required position on the positioning table. The setting of the limiting plate can limit the movement range of the slider and prevent the sliders from colliding with each other during movement.

[0012] Optionally, the driving mechanism includes a drive motor, multiple transmission gears, and two toothed belts. The drive motor is fixedly installed on the inner wall of the positioning platform. Two of the transmission gears are fixedly connected to the output shaft of the drive motor, and the remaining transmission gears are respectively fixedly connected to the outer wall of the bidirectional threaded rod. The two toothed belts are respectively rotatably sleeved on the outer side of the two transmission gears. The inner wall of the positioning platform is provided with a through groove for installing the transmission gears and toothed belts, and the through groove communicates with two sliding grooves.

[0013] By adopting the above technical solution, the position of the positioning structure can be automatically adjusted, reducing the tediousness of manual operation and improving work efficiency. The through-slot design allows the transmission gears and toothed belts to be compactly installed in the positioning table without occupying extra space, while also facilitating maintenance and repair.

[0014] Optionally, each of the support rods has a positioning groove at its upper end for the insertion of a positioning rod.

[0015] By adopting the above technical solution, the positioning rod can be easily inserted into the upper end of the support rod, which facilitates the installation and replacement of the positioning rod and improves the convenience of operation.

[0016] Optionally, a servo motor is fixedly connected to the inner wall of the base, and a bevel gear is fixedly connected to one end of the output shaft of the servo motor. A transmission gear ring, which is fixedly connected to the outer wall of the transmission rod, is meshed with one side of the bevel gear.

[0017] By adopting the above technical solution, the transmission rod can be driven to rotate through bevel gears and transmission ring gears, thus achieving stable rotation of the transmission rod, providing power support for the rotation function of the worktable, and precisely controlling the rotation speed and angle of the transmission rod. This can be adjusted according to different painting needs, making the painting operation more flexible.

[0018] Optionally, the upper and lower ends of the base are each equipped with bearings connected to the transmission rod.

[0019] By adopting the above technical solution, not only can the transmission rod be stably supported, making it more stable during rotation and preventing it from shaking or misaligning, but the friction between the transmission rod and the base can also be reduced, thereby improving the service life of the transmission rod and the stability of the worktable.

[0020] Optionally, a baffle plate is fixedly connected to the middle of the transmission rod.

[0021] By adopting the above technical solution, the baffle can block the paint mist generated during the painting process, prevent the paint mist from spreading into the base, prevent it from affecting the rotation of the transmission rod, and ensure the rotation efficiency of the transmission rod.

[0022] In summary, this application has the following beneficial effects: 1. The workbench in this application can adapt to the painting needs of wooden furniture of different sizes, expand the scope of application of the workbench, and does not require replacing the workbench or performing complicated fixing operations, thereby improving the efficiency and quality of furniture painting.

[0023] 2. This application enables a more stable connection between the support rod and the positioning table through the connecting parts. Through the design of the slider and the groove, as well as the cooperation of the bidirectional threaded rod, the limiting plate and other structures, the movement distance and range of the slider can be precisely controlled, reducing frictional resistance and ensuring smooth movement of the positioning structure when adjusting its position.

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] This application discloses a workbench for painting wooden furniture.

[0028] Reference Figure 1 The workbench for painting wooden furniture includes a base 1, a transmission rod 2 rotatably mounted in the middle of the base 1, and a positioning platform 3 fixedly mounted on the upper end of the transmission rod 2. The base 1 is installed inside the spray booth to ensure structural stability. The transmission rod 2 supports the positioning platform 3, allowing it to rotate on the upper side of the base 1 via the transmission rod 2. Positioning structures 4 are slidably mounted at both ends of the positioning platform 3 to restrict the position of the furniture. These positioning structures 4 limit the position of the wooden furniture and reduce the contact area between the wooden furniture and the positioning platform 3, thereby enabling multi-directional painting of the wooden furniture.

[0029] Reference Figure 1 , Figure 2 and Figure 3A servo motor 12 is fixedly connected to the inner wall of the base 1. A bevel gear 13 is fixedly connected to one end of the output shaft of the servo motor 12. A transmission gear ring 14, which is fixedly connected to the outer wall of the transmission rod 2, is meshed with one side of the bevel gear 13. When the servo motor 12 drives the bevel gear 13 to rotate the transmission gear ring 14, it can drive the transmission rod 2 to rotate, thereby driving the positioning table 3 to rotate. Bearings 11 connected to the transmission rod 2 are installed at both the upper and lower ends of the base 1. The bearings 11 are used to ensure the rotation efficiency of the transmission rod 2, reduce the friction between the transmission rod 2 and the base 1, and improve the service life of the structure. A baffle plate 10 is fixedly connected to the middle of the transmission rod 2. The baffle plate 10 can block the paint spraying and prevent the paint from being sprayed on the bearings 11, thus avoiding its impact on the rotation effect of the transmission rod 2.

[0030] Reference Figure 4 , Figure 5 and Figure 6 The positioning structure 4 has two parts, including a support rod 41 mounted on the upper side of the positioning platform 3 and a positioning rod 42 mounted on the upper side of the support rod 41. The support rod 41 is used to hold the wooden furniture higher than the upper side of the positioning platform 3, and the positioning rod 42 is used to reduce the contact area between the wooden furniture and the support rod 41. Each support rod 41 has a positioning groove 411 at its upper end for the positioning rod 42 to be inserted. The positioning groove 411 allows for quick installation or removal of the positioning rod 42 and also reduces the possibility of misalignment during use. The two ends of the two support rods 41 are respectively fixedly connected to the connecting parts 43 connected to the positioning platform 3. The lower sides of both ends of the positioning platform 3 are respectively provided with sliding grooves 5 for the connecting parts 43 to slide. The connection between the connecting parts 43 and the inner wall of the sliding grooves 5 can ensure the stability of the support rods 41 while facilitating the adjustment of the position of the support rods 41. The positioning platform 3 is equipped with a drive mechanism 6 for adjusting the positions of the two positioning structures 4. The drive mechanism is used to quickly adjust the position of the positioning structure 4 on the positioning platform 3 so that it can meet the placement requirements of wooden furniture of different sizes.

[0031] Reference Figure 5 and Figure 6The connecting member 43 includes a connecting rod 431 fixedly connected to the support rod 41 and a slider 432 fixedly connected to the lower end of the connecting rod 431. The slider 432 is slidably connected to the inner wall of the slide groove 5. The slider 432 is used to ensure the stability of the connection between the connecting rod 431 and the positioning table 3, and to allow the connecting rod 431 to move along the positioning table 3 with the slider 432. The connecting rod 431 is used to support the support rod 41 and ensure that it is stably installed on the upper side of the positioning table 3. Each slide groove 5 has a bidirectional threaded rod 7 rotatably connected to the inner wall of the opposite sides. The two ends of each bidirectional threaded rod 7 are respectively threaded to the inner wall of the slider 432. When the bidirectional threaded rod 7 rotates, it can simultaneously drive the two sliders 432 to move towards each other or away from each other in the slide groove 5. Two limiting plates 8 are provided between each pair of sliders 432 and fixedly connected to the outer wall of the bidirectional threaded rod 7. The limiting plates 8 are used to limit the sliding range of the sliders 432 and prevent the two positioning structures 4 from colliding with each other when moving.

[0032] Reference Figure 5 and Figure 6 The drive mechanism 6 includes a drive motor 61 fixedly installed inside the positioning platform 3, multiple transmission gears 62 respectively installed on the output shaft of the drive motor 61 and the outer walls of the two bidirectional threaded rods 7, and two toothed belts 63 rotatably sleeved on the outside of the two transmission gears 62. Two transmission gears 62 are fixedly connected to the output shaft of the drive motor 61, and the remaining transmission gears 62 are fixedly connected to the outer walls of the bidirectional threaded rods 7. When the drive motor 61 operates, the two bidirectional threaded rods 7 can be driven to rotate simultaneously through the cooperation of the transmission gears 62 and the toothed belts 63. The inner wall of the positioning platform 3 has through grooves 9 for mounting the transmission gears 62 and the toothed belts 63, and the through grooves 9 communicate with the two sliding grooves 5, providing a stable operating space for the transmission gears 62 and the toothed belts 63, ensuring the stable operation of the drive mechanism 6.

[0033] The implementation principle of the wooden furniture spray painting workbench in this application embodiment is as follows: In use, the first step is to start the drive motor 61 according to the type of wooden furniture. The output shaft of the drive motor 61 drives two transmission gears 62 to rotate, and two toothed belts 63 drive two other transmission gears 62 to rotate, thereby driving two bidirectional threaded rods 7 to rotate synchronously. This, in turn, drives the sliders 432 at both ends to slide in the slide groove 5, and drives the support rods 41 to move on the positioning platform 3 through the connecting rod 431 until the two support rods 41 move to the appropriate position, at which point the drive motor 61 stops. Then, place the wooden furniture on the positioning platform 3 until it contacts the positioning rods 42 on the upper side of the support rods 41, thus completing the placement of the wooden furniture. Step 2: Start the servo motor 12 to drive the bevel gear 13 to rotate. With the meshing of the bevel gear 13 and the transmission gear ring 14, the transmission rod 2 is driven to rotate in the two bearings 11 inside the base 1, thereby driving the positioning table 3 to rotate and causing the wooden furniture to rotate with the positioning table 3. At this time, the wooden furniture can be painted in all directions by the painting equipment. Step 3: After the painting is completed, remove the wooden furniture and use the painting equipment again to touch up the paint on the contact parts between the wooden furniture and the positioning rod 42, thus completing the painting work of the wooden furniture.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
