Technical Field
[0001] This utility model relates to the field of spraying equipment technology, and in particular to a spraying device for medal making with a drying function. Background Technology
[0002] Spray painting is a crucial step in medal production, primarily aimed at beautifying the medals, enriching their colors, and enhancing their overall visual appeal. Spray painting allows for the addition of various colors, patterns, or textures to meet diverse design needs and aesthetic standards. Current medal painting equipment typically uses nozzles to apply paint or other materials to the medal's surface. Since the paints used in the spraying process usually contain solvents, these solvents need to evaporate after spraying to ensure the coating's drying and curing. Therefore, the sprayed medals need to be dried. However, existing medal spraying and drying equipment are separate systems, requiring the medals to be transported to the drying equipment after spraying. While this method effectively sprays and dries the medals, it is quite cumbersome. Utility Model Content
[0003] This invention provides a spraying device for medal making with a drying function, which solves the problems in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A spraying device for medal making with a drying function includes an operating table, on both sides of which are provided with placement plates for placing medals.
[0006] The top of the operating table is provided with a bracket, and the bottom of the bracket is symmetrically provided with cylinders. The bottom of the cylinders is connected to a connecting plate. The two sides of the connecting plate are respectively connected to mounting plates, and the bottom of the mounting plate is provided with a nozzle. The bottom of the connecting plate is connected to a connecting strip, and one side of the connecting strip is connected to a first rack.
[0007] The operating table is connected to two sides of a first L-shaped plate, and a screw is rotatably connected between the first L-shaped plates. A first gear connected to a first rack is connected to the center of the surface of the screw, and a horizontal plate is threaded to both sides of the surface of the screw. A heating device is installed inside the bottom end of the horizontal plate.
[0008] The above structure facilitates the downward movement of the connecting plate, mounting plate, and nozzle via the cylinder. Simultaneously, it moves the connecting strip and the first rack on the surface of the first gear, causing the first gear to rotate the screw. This allows the horizontal plates on both sides of the screw surface to move away from above the placement plate, moving the nozzle above the medal for spraying. After spraying, the cylinder resets, the connecting strip and the first rack move upward, and the first gear rotates in the opposite direction, resetting the horizontal plates on both sides of the screw surface. The heated plate at the bottom of the horizontal plate dries the sprayed medal. The bottom of the operating table has a through groove for the movement of the connecting strip and the first rack.
[0009] The threads on both sides of the screw surface are arranged in opposite directions.
[0010] The above structure allows the threaded plates on both sides of the screw to move in opposite directions or in opposite directions simultaneously when the screw is rotating.
[0011] The operating table has a first moving groove and a second moving groove on each side for moving the horizontal plate and the placement plate.
[0012] With the above structure, the first and second moving slots facilitate the movement of the horizontal plate and the placement plate inside the operating table.
[0013] The two sides of the operating table are connected to second L-shaped plates, and the two L-shaped plates are connected to each other by guide rods that are movably connected to the horizontal plate.
[0014] With the above structure, the guide rod facilitates the limiting movement of the horizontal plate.
[0015] Connecting pipes are installed on both sides of the operating table, and a partition is fixedly connected to the surface of the connecting pipe. An annular plate is movably connected to the surface of the connecting pipe. An exhaust fan and a filter element are also installed inside the connecting pipe.
[0016] With the above structure, the exhaust fan is used to remove the odors generated during the drying of medals, while the filter element filters out the harmful gases in the odors. The surfaces of the partition and the operating table are provided with threaded holes, and the threaded rod is connected to the inside of the threaded hole.
[0017] The inner wall of the annular plate is connected to a second rack, and the surface of the second rack is connected to a second gear, and the surface of the second gear is connected to a threaded rod.
[0018] The above structure facilitates the rotation of the annular plate, allowing the second rack on its inner wall to move on the surface of the second gear, thereby causing the second gear to drive the threaded rod to rotate.
[0019] The annular plate has a groove inside, and a slider that is rotatably connected to the bottom end of the threaded rod is slidably connected inside the groove. A positioning rod is provided at the top end of the threaded rod.
[0020] The above structure facilitates the movement of the annular plate at the top of the threaded rod via the slider and groove, and also allows the threaded rod to rotate on the surface of the slider. The positioning rod is used to position the plate by passing through the threaded hole on the surface of the operating table, thus preventing misalignment between the threaded hole on the operating table and the partition plate when the annular plate is rotated.
[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0022] 1. In this utility model, the operation of the cylinder can move the nozzle downwards and move the horizontal plate and heating equipment away from the top of the medal to both sides, so as to move the nozzle to the top of the medal for spraying. After the spraying is completed, the cylinder and nozzle are reset, and the horizontal plate and heating equipment can be moved to the top of the sprayed medal for drying. This equipment can not only spray the medal but also dry it, and the operation is simple.
[0023] 2. In this utility model, the exhaust fan and filter element installed inside the connecting pipe can discharge and filter the odor generated during medal drying, avoiding any impact on the surrounding environment. At the same time, the connecting pipe can be disassembled by rotating the annular plate, making it convenient to clean and maintain its interior. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figures 1-3 A spraying device for medal production with a drying function includes an operating table 1. Placement plates 2 for placing medals are installed on both sides of the operating table 1, and a bracket 3 for supporting a cylinder 4 is installed at the top of the operating table 1. The output end of the cylinder 4 is connected to a connecting plate 5, which facilitates the connection of mounting plates 6 on both sides, each equipped with a nozzle 7. This allows the cylinder 4 to drive the connecting plate 5, mounting plates 6, and nozzles 7 downwards. A connecting strip 8 is connected to the bottom of the connecting plate 5, and a first rack 9 is connected to the surface of the connecting strip 8. Simultaneously, first L-shaped plates 10 for supporting screws 11 are installed on both sides of the operating table 1, and a first gear 12 connected to the first rack 9 is connected to the center of the first L-shaped plate 10. Furthermore, the screw 11 has horizontal plates 13 for installing heating equipment threadedly connected to both sides of its surface. This allows the first rack 9 to move on the surface of the first gear 12 when the cylinder 4 drives the connecting plate 5, nozzle 7, connecting strip 8, and first rack 9 to move downwards. This allows the first gear 12 to drive the screw 11 to rotate, moving the horizontal plates 13 and heating equipment on both sides of the screw 11 away from the top of the medal. The nozzle 7 is then moved above the medal for spraying. After spraying, the cylinder 4 and nozzle 7 are reset, allowing the first gear 12 to rotate in the opposite direction. This moves the horizontal plates 13 and heating equipment above the medal for drying. One end of the nozzle 7 is connected to a pump and a paint tank, and the cylinder 4 and heating equipment are all connected to a controller.
[0031] Furthermore, in order to ensure that the horizontal plates 13 on both sides of the screw 11 can move in opposite directions or move in opposite directions at the same time, the threads on both sides of the screw 11 need to be reversed. At the same time, in order to ensure that the horizontal plates 13 can move in a limited position, the other end of the horizontal plates 13 needs to be connected to the guide rod 17. The guide rod 17 is connected to the second L-shaped plate 16 connected to the operating table 1. In addition, a first moving groove 14 and a second moving groove 15 need to be opened on the surface of the operating table 1. The first moving groove 14 is to facilitate the movement of the horizontal plates 13, and the second moving groove 15 is to facilitate the removal of the placement plate 2 and medals from the inside of the operating table 1.
[0032] Furthermore, to ensure the removal and filtration of odors generated during drying, connecting pipes 18 are installed on both sides of the operating table 1. The interior of each connecting pipe 18 contains an exhaust fan and a filter element. To facilitate the installation and removal of the connecting pipes 18, a partition plate 19 is connected to the surface of the connecting pipes 18. The partition plate 19 and the surface of the operating table 1 are annularly and equidistantly threaded grooves. For quick installation, a second rack 21 is installed on the inner wall of the annular plate 20, and a second gear 22 is connected to the surface of the second rack 21. A threaded rod 23 is connected to the surface of the second gear 22. To enable the annular plate 20 to move at the top of the threaded rod 23 and to rotate the threaded rod 23, a sliding groove 24 is opened at the bottom of the annular plate 20. A slider 25 slidably connected inside the sliding groove 24 needs to be positioned between the sliding groove 24 and the threaded rod 23. For rotational connection, the annular plate 20 can rotate at the bottom end of the threaded rod 23 via the slide groove 24 and the slider 25. At the same time, when the second rack 21 moves on the surface of the second gear 22, the second gear 22 can drive the threaded rod 23 to rotate on the surface of the slider 25. Since the threaded rod 23 and the threaded groove on the surface of the partition plate 19 are threadedly connected, it can rotate and move to facilitate the threaded rod 23 to be rotated into the threaded groove on the surface of the operating table 1 for installation, and vice versa for easy disassembly. In order to ensure that the threaded groove on the partition plate 19 and the threaded groove on the operating table 1 will not be misaligned when the annular plate 20 is rotated, a positioning rod 26 needs to be connected to the top end of the threaded rod 23. The positioning rod 26 can be inserted into the threaded groove of the partition plate 19 and the operating table 1 for positioning, thereby preventing the two threaded grooves from being misaligned.
[0033] The working principle is as follows: the operation of cylinder 4 drives the connecting plate 5, mounting plate 6, nozzle 7, connecting strip 8, and first rack 9 to move downwards. The first rack 9 can move on the surface of the first gear 12, thereby causing the first gear 12 to drive the screw 11 to rotate. This allows the horizontal plates 13 on both sides of the screw 11 to move in a limited position via guide rod 17, moving the horizontal plates 13 and the heating device at their bottom ends away from above the medal. At the same time, the nozzle 7 can move above the medal for spraying. After spraying, cylinder 4 resets, causing the connecting strip 8 to drive the first rack 9 to move upwards, thereby causing the first gear 12 to rotate in the opposite direction. This allows the horizontal plates 13 on both sides of the screw 11 and the heating device to move above the sprayed medal for heating and drying. Meanwhile, the exhaust fan inside the connecting pipe 18 filters out the odors generated during drying, preventing them from affecting the surrounding environment. After drying, the placement plate 2 can be removed through the second moving groove 15 to facilitate the removal of the sprayed and dried medal.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
