[0002] Metal products are one of the most commonly used products nowadays. During the manufacturing process of metal workpieces, in order to ensure the functionality of the metal products, the metal surface will be painted. After painting, the metal surface needs to be dried to keep the metal surface dry.

[0003] According to a metal surface high-efficiency spraying equipment disclosed in Chinese patent announcement No. CN218394366U, the patent can shield and protect the drying component by setting a shielding member to prevent the paint from adhering to the surface of the drying component when the paint is sprayed, thereby improving the overall use effect. The placement plate is arranged inside the box body. In order to enable it to rotate smoothly, it is usually arranged in a fit with the inner bottom wall of the box body. There must be a certain gap between the workpieces. The paint sprayed downward is easy to accumulate inside the gap. When the paint accumulates too much, it will affect the rotation smoothness of the placement plate, resulting in the metal workpiece being unable to be sprayed at a uniform number of revolutions, affecting the spraying effect. Moreover, since the gap is too small, it is extremely inconvenient to clean it later. In this regard, the present application provides a metal workpiece paint spraying box to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0030] See also Figure 1-4 The present application provides a technical solution: a metal workpiece paint spray box, comprising a spray box body 1, a workpiece placement tray 2 is slidably installed on the inner bottom wall of the spray box body 1, a transmission component 300 for driving the workpiece placement tray 2 to rotate is installed at the bottom of the spray box body 1, a spray component for spraying and drying is installed on the outer side of the spray box body 1, a gap protection component 500 located on the outer side of the workpiece placement tray 2 is installed on the inner side of the spray box body 1, and a box door body 6 is hinged on the front of the spray box body 1 through a hinge; through the coordinated use of the workpiece placement tray 2, the gap protection component 500, the spraying mechanism 401 and the drying fan 405 on the inner side of the spray box body 1, a certain protection can be provided for the gap between the structure for placing the workpiece and the spray box, so that the paint can be prevented from accumulating in the gap for a long time to affect the rotation spraying of the workpiece during the spraying work, and at the same time, it is convenient for the subsequent cleaning work to be carried out, so that the rotation of the workpiece can be kept in a stable and smooth state, thereby effectively improving the practicality of the paint spray box.

[0031] In this embodiment, the gap protection component 500 is a structure used to provide certain protection for the gap of the workpiece placement structure.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, the gap protection assembly 500 includes a square groove 501 opened on the top of the workpiece placement plate 2, a square frame 502 inserted into the inner side of the square groove 501, four connecting rods 503 fixed to the outside of the square frame 502 and evenly distributed, a circular frame 504 fixed between the four connecting rods 503 at one end away from the square frame 502, and a film 505 bonded between the outer side of the circular frame 504 and the top of the square frame 502.

[0033] It should be noted that the circular frame 504 is located on the outside of the workpiece placement plate 2, and the end of the connecting rod 503 away from the square frame 502 is tilted downward, and the bottom of the circular frame 504 does not fit the inner bottom wall of the spray box body 1, so that after the square frame 502 is inserted into the inner side of the square groove 501, the circular frame 504 can be driven to move together through the four connecting rods 503, wherein the distance between the bottom of the circular frame 504 and the inner bottom wall of the spray box body 1 is between three millimeters and five millimeters.

[0034] In addition, the film 505 can be adhered by setting adhesive stickers at multiple points, which is convenient for pasting and connection and also convenient for tearing off and replacement. The film 505 can be folded and stuffed into the bottom of the circular frame 504. By utilizing the tension of the film 505 itself, it can play an elastic protection role for the gap between the bottom of the circular frame 504 and the inner bottom wall of the spray box body 1, and at the same time it can also block the paint to a certain extent. Even if the paint passes through the bottom of the film 505 and enters the inner circle part of the circular frame 504, it is difficult to accumulate at the bottom of the workpiece placement tray 2, so that the workpiece placement tray 2 can rotate stably for a long time, and there is almost no need to clean the gap at the bottom of the workpiece placement tray 2, so that the workload of the staff is reduced.

[0035] In this embodiment, the transmission assembly 300 is a structure for driving the workpiece placement plate 2 to rotate smoothly and stably.

[0036] like Figure 1 and Figure 4 As shown, the transmission assembly 300 includes a fixed box 301 fixed to the bottom of the spray box body 1, a fixed block 302 fixed to the inner bottom wall of the fixed box 301, a driving mechanism 303 fixedly installed on the top of the fixed block 302, a transmission rod 304 rotatably connected between the bottom of the spray box body 1 and the inner bottom wall of the fixed box 301 through a bearing, a driven bevel gear 305 fixed to the outside of the transmission rod 304, and an active bevel gear 306 fixed to the output shaft of the driving mechanism 303.

[0037] It should be noted that the driving mechanism 303 can be a servo motor, which has the advantages of smooth transmission and small vibration. The front of the fixed box 301 is open, and the front of the fixed box 301 is connected to a baffle by screws. The top of the transmission rod 304 passes through the bottom of the spray box body 1 and is fixedly connected to the bottom of the workpiece placement tray 2. The bottom of the workpiece placement tray 2 is a smooth surface and fits with the inner bottom wall of the spray box body 1, so that the workpiece placement tray 2 can be stably rotated through the transmission rod 304, and the left side of the active bevel gear 306 is meshed with the right side of the driven bevel gear 305, so that the active bevel gear 306 can drive the driven bevel gear 305 to rotate.

[0038] In this embodiment, the spraying assembly is a structure used for spraying metal workpieces.

[0039] like Figure 1 and Figure 4 As shown, the spray assembly includes a spray mechanism 401 fixedly mounted on the left side wall of the spray box body 1, a feed pipe 402 fixed on the left side of the spray mechanism 401 and passing through the left side of the spray box body 1, a mounting hole 403 opened on the top of the spray box body 1, a dust shield box 404 detachably mounted on the top of the spray box body 1, a drying fan 405 fixedly mounted on the inner side of the mounting hole 403, two electric heating lamps 406 fixedly mounted on the inner side of the mounting hole 403, an electric push rod 407 fixedly mounted on the inner top wall of the spray box body 1, two slide rails 408 fixedly mounted on the inner top wall of the spray box body 1, and a baffle 409 slidably connected between the opposite sides of the two slide rails 408.

[0040] It should be noted that the dust shield box 404 is located at the top of the mounting hole 403, so that the dust shield box 404 can filter dust from the air entering the mounting hole 403. The two electric heating lamps 406 are respectively located on both sides of the drying fan 405, which can effectively heat the airflow inside the mounting hole 403.

[0041] In addition, the electric push rod 407 is located on the back side of the mounting hole 403, the maximum stroke distance of the electric push rod 407 is greater than the width of the mounting hole 403, the baffle plate 409 is fitted against the top of the spray box body 1, and the baffle plate 409 is located at the bottom of the mounting hole 403, so that the baffle plate 409 can be pushed to the bottom of the mounting hole 403 by the electric push rod 407 and provide shielding and protection therefrom.

[0042] At the same time, the slide rail 408 is a straight structure with openings on the top and one side, and the two slide rails 408 are symmetrically distributed on the left and right, so that the baffle plate 409 can slide between the inner sides of the two slide rails 408, allowing the slide rail 408 to support the baffle plate 409.

[0043] It should also be noted that the spraying mechanism 401 is a mechanism composed of a small booster pump and an atomizing nozzle, which can pressurize the paint inside the feed pipe 402 and then spray it out. It is an existing public and commonly used spraying technology and structure.

[0044] The working principle of the above embodiment is:

[0045] When spraying the metal workpiece, the square frame 502 is inserted and placed inside the square groove 501, the film 505 is moved to the top of the square frame 502 and pressed downward, so that the film 505 is fitted on the top of the workpiece placement tray 2, and the film 505 is pasted on the top of the square frame 502 and the top of the circular frame 504, and the film 505 is folded to cover it and pasted on the bottom of the circular frame 504, so that the film 505 can provide a certain degree of protection for the top and outer side of the workpiece placement tray 2 and the gap between the bottom and the inner bottom wall of the spray box body 1, and the metal workpiece is placed on the top of the workpiece placement tray 2 covered by the film 505, the box door body 6 is closed, and the driving mechanism 303 is started, and the driven bevel gear 306 is driven to move the driven bevel gear 306. The gear 305 rotates, causing the transmission rod 304 to rotate and driving the workpiece placement plate 2 to rotate, so that the metal workpiece can rotate smoothly, and the spraying mechanism 401 is started, and the spray material entering through the feed pipe 402 can be sprayed on the surface of the metal workpiece for spraying. After the spraying is completed, the electric push rod 407 is started to drive the baffle plate 409 away from the bottom of the mounting hole 403, so that the electric heating lamp 406 and the drying fan 405 are not blocked by the baffle plate 409, and the drying fan 405 is started, so that the outside air is filtered by the dustproof mesh box 404 and enters the interior of the spray box body 1, and then blown on the surface of the metal workpiece after being heated by the electric heating lamp 406 to dry it, thereby completing the paint spraying and drying of the metal workpiece.

[0046] Compared with the prior art, the metal workpiece paint spray box can provide certain protection for the gap between the structure for placing the workpiece and the spray box through the coordinated use of the workpiece placement plate 2, the gap protection assembly 500, the spray mechanism 401 and the drying fan 405 on the inner side of the spray box body 1, thereby preventing the paint from accumulating in the gap for a long time during the spraying work and affecting the rotation spraying of the workpiece. At the same time, it is also convenient for the subsequent cleaning work, so that the rotation of the workpiece can maintain a stable and smooth state, thereby effectively improving the practicality of the paint spray box and solving the problem that the paint of the prior art spray equipment is easily accumulated between the structure for placing the workpiece and the inner wall of the spray box during spraying, thereby causing the rotation of the workpiece to be hindered to a certain extent.

[0047] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.
