[0004] The device of this patent can spray different surfaces of the sheet metal part, thereby improving the spraying efficiency of the sheet metal part. However, when the device of this patent performs double-sided painting on the sheet metal part, it requires two operations, which increases the production cycle and cost, and thus is inconvenient to meet the usage requirements of the staff. Content of the Utility Model

[0005] The purpose of the utility model is to provide a double-sided painting device for sheet metal.

[0006] The technical problem solved by the utility model is that the existing device requires two operations when performing double-sided painting on the sheet metal part, thereby increasing the production cycle and cost of the device.

[0007] The utility model can be realized through the following technical solutions: A double-sided painting device for sheet metal plates, including a painting box. A sheet metal plate fixing mechanism is arranged in the inner cavity of the painting box. The sheet metal plate fixing mechanism includes a filtrate plate fixed between the two inner side walls of the painting box. A plurality of evenly distributed filter holes are penetrated through the inner cavity of the filtrate plate. The arrangement of the plurality of filter holes facilitates guiding the redundant paint liquid generated during the painting process to the bottom end of the inner cavity of the painting box, thereby facilitating its subsequent recovery. A guiding groove is opened on the top wall of the filtrate plate. A fixing plate for centering the sheet metal plate in the inner cavity of the painting box is fixedly installed between the two inner side walls of the guiding groove. Two clamping plates for clamping the sheet metal plate are symmetrically and slidably connected to the top end of the inner cavity of the painting box. A double-sided painting mechanism is also arranged in the inner cavity of the painting box. The double-sided painting mechanism includes a rotating door rotatably connected to the front of the painting box. Painting trays for painting the sheet metal plate are arranged on the inner walls of the rotating door and the painting box. The size specifications of the painting trays are adapted to the sheet metal plate, thereby facilitating double-sided painting of it at one time.

[0008] A further technical improvement of the utility model lies in that: The double-sided painting mechanism further includes a paint pump fixedly installed on the rotating door or the painting box. The output end of the paint pump is communicated with the painting tray through a hose.

[0009] A further technical improvement of the utility model lies in that: Two electric telescopic rods are symmetrically and fixedly installed on the inner walls of the rotating door and the painting box. The output end of the electric telescopic rod is fixedly connected to the painting tray.

[0010] A further technical improvement of the utility model lies in that: Anti-slip pads are bonded to the opposite sides of the two clamping plates. The arrangement of the anti-slip pads facilitates the device to firmly fix the sheet metal plate.

[0011] A further technical improvement of the utility model lies in that: A driving component for enabling the two clamping plates to move relative to each other is arranged at the top end of the inner cavity of the painting box. The driving component includes a bidirectional screw rod rotatably connected to the top end of the inner cavity of the painting box. Threaded sleeves fixedly connected to the clamping plates are threadedly sleeved on the two sections of external threads with opposite rotation directions of the bidirectional screw rod. Rotating the bidirectional screw rod enables the two threaded sleeves to move relative to each other.

[0012] A further technical improvement of the utility model lies in that: A drain pipe for discharging the waste paint liquid in the painting box is fixedly installed at the bottom end of one side of the painting box.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. After the sheet metal is fixed between two spray paint trays, the present utility model can adaptively adjust the two spray paint trays according to the thickness of the sheet metal that needs to be spray painted. When adjusting, the electric telescopic rod is driven, and the distance between the spray paint tray and the sheet metal can be easily changed through the telescopic movement of the electric telescopic rod. After adjustment, the two paint pumps are driven simultaneously, and through the coordinated setting of the paint pumps, spray paint trays, and hoses, the double-sided spray painting work of the sheet metal can be completed at one time, which is beneficial to shortening the production period of the sheet metal and reducing the production cost of the sheet metal, and thus facilitating the satisfaction of the usage requirements of the staff.

[0015] 2. The present utility model enables the sheet metal to be double-sided spray painted to move along the guiding groove opened on the top wall of the filtrate plate by opening the rotating door until the back surface of the sheet metal abuts against the fixed plate in the guiding groove. At this time, the sheet metal is located in the middle of the inner cavity of the spray paint box, and thus the distance between the sheet metal and the two spray paint trays can be made consistent. Finally, the bidirectional screw is rotated. Since the threads on the outer surface of the bidirectional screw are two sections with opposite helix directions, the rotation of the bidirectional screw facilitates driving the two screw sleeves to move relatively, and the corresponding clamping plates are driven to move synchronously through the movement of the screw sleeves, thereby facilitating the fixation of the sheet metal, ensuring the consistency of the double-sided spray painting of the sheet metal, and thus being beneficial to improving the overall spray painting effect of the equipment and facilitating use.

[0028] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and their effects of the present utility model as follows

[0029] Please refer to Figures 1-5 As shown, this embodiment provides a technical solution, a double-sided painting device for sheet metal plates, including a painting box 1. A filtrate plate 2 is fixedly installed between the two inner side walls of the painting box 1. A waste liquid collection area 21 is formed below the filtrate plate 2 in the inner cavity of the painting box 1, and a working area 22 is formed above the filtrate plate 2 in the inner cavity of the painting box 1. A drain pipe 23 for discharging the waste liquid in the waste liquid collection area 21 is fixedly installed at the bottom end of one side of the painting box 1. A control valve is provided in the drain pipe 23. Through the setting of the control valve, it is convenient for the staff to control the flow rate of the discharged waste liquid according to the actual usage situation

[0030] Two clamping plates 3 are symmetrically and slidably connected in the inner cavity of the working area 22. Anti-slip pads 31 are bonded to the opposite sides of the two clamping plates 3. The anti-slip pads 31 are preferably rubber pads. Through the setting of the rubber pads, it is convenient for the clamping plates 3 to better fix the sheet metal plates

[0031] More specifically, the specifications of the clamping plates 3 and the anti-slip pads 31 can fully cover the inner wall of the painting box 1, so that when the device sprays paint on the sheet metal plates, the excess paint liquid will not splash onto the inner wall of the painting box 1, reducing the cleaning burden of the staff. And by bonding the anti-slip pads 31 to one side of the clamping plates 3, it is not only convenient to replace the anti-slip pads 31 regularly, but also further reduces the cleaning burden of the staff

[0032] A driving mechanism for making the two clamping plates 3 move relative to each other is provided in the inner cavity of the painting box 1. The driving mechanism includes an inner groove 32 opened in the inner cavity of the painting box 1. A bi-directional screw 33 is rotatably connected between the two inner side walls of the inner groove 32 through bearings. Two sections of external threads with opposite thread directions are provided on one side of the bi-directional screw 33 close to the end. Screw sleeves 34 slidably connected to the inner wall of the inner groove 32 are threadedly sleeved on the two sections of external threads of the bi-directional screw 33. The screw sleeves 34 are fixedly connected to the clamping plates 3

[0033] A servo motor 35 for driving the bi-directional screw 33 to rotate is fixedly installed at the top end of one side of the painting box 1

[0034] The inner cavity of the filter plate 2 is provided with a guiding mechanism for centering the sheet metal plate. The guiding mechanism includes a guiding groove 24 opened on the top wall of the filter plate 2. A fixing plate 25 is fixedly installed between the two inner side walls of the guiding groove 24. The fixing plate 25 is located in the middle of the inner cavity of the painting box 1. A plurality of uniformly distributed through holes are penetrated through the inner cavity of the fixing plate 25. The arrangement of the plurality of through holes avoids the influence of the fixing plate 25 on the painting work of the painting disc 52 during use.

[0035] A rotating door 4 is rotatably connected to the front of the painting box 1 through a hinge. Painting mechanisms for painting the sheet metal plate are arranged on the front of the rotating door 4 and the back of the painting box 1. The painting mechanism includes a paint pump 5 fixedly installed on the rotating door 4 or the painting box 1. The output end of the paint pump 5 is communicated with a hose 53. The input end of the paint pump 5 is externally connected to a paint supply tank. Two electric telescopic rods 51 are symmetrically and fixedly installed on the inner wall of the rotating door 4 or the painting box 1. The output end of the electric telescopic rod 51 is fixedly installed with a painting disc 52 adapted to the sheet metal plate. One end of the hose 53 far away from the paint pump 5 is communicated with the painting disc 52;

[0036] More specifically, by double-sided painting the sheet metal plate in the inner cavity of the painting box 1, the unpleasant smell during painting is avoided from overflowing, which is beneficial to improving the working environment of the staff. After painting is completed, opening the rotating door 4 not only facilitates the staff to take out the painted sheet metal plate, but also facilitates cleaning the painting box 1.

[0037] When the present utility model is in use, the rotating door 4 is opened to make the sheet metal plate to be double-sided painted move along the guiding groove 24 opened on the top wall of the filter plate 2 until the back surface of the sheet metal plate abuts against the fixing plate 25 in the guiding groove 24. At this time, the sheet metal plate is located in the middle of the inner cavity of the painting box 1, so that the distance between the sheet metal plate and the two painting discs 52 can be made consistent. Finally, the servo motor 35 is driven to rotate the bidirectional screw rod 33. Since the threads on the outer surface of the bidirectional screw rod 33 are two sections with opposite helix directions, the rotation of the bidirectional screw rod 33 facilitates driving the two screw sleeves 34 to move relatively. The movement of the screw sleeves 34 drives the corresponding clamping plates 3 to move synchronously, thereby facilitating the fixation of the sheet metal plate;

[0038] After the sheet metal plate is fixed, the rotating door 4 is closed. The two painting discs 52 are adaptively adjusted according to the thickness of the sheet metal plate to be painted. During adjustment, the electric telescopic rod 51 is driven. The telescopic movement of the electric telescopic rod 51 facilitates changing the distance between the painting disc 52 and the sheet metal plate. After adjustment, the two paint pumps 5 are driven simultaneously. Through the cooperative setting of the paint pump 5, the painting disc 52 and the hose 53, the double-sided painting work of the sheet metal plate can be completed at one time, which is beneficial to shortening the production period of the sheet metal plate, reducing the production cost of the sheet metal plate, and further facilitating meeting the use requirements of the staff.

[0039] During the spraying process, the excess waste paint liquid will enter the bottom end of the inner cavity of the spraying box 1 through the filter holes in the filter plate 2, and it is convenient to recycle it by opening the control valve in the drain pipe 23.

[0040] After double-sided spraying of the sheet metal plate, first open the rotating door 4. After the paint liquid is completely dry, then release the fixation of the sheet metal plate, and it can be taken out.

[0041] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
