[0019] Example 1

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a spraying device for guardrail processing, comprising a cart 1, a paint storage box 2 is fixed above the cart 1, the paint storage box 2 is used to store paint, and an extraction pump 3 is fixed on the paint storage box 2, a delivery pipe is installed between the paint storage box 2 and the extraction pump 3, with the help of the extraction pump 3, the paint in the paint storage box 2 is conveniently extracted, and then transported to the paint spraying part 11 for spraying operation, connecting plates 4 are fixed on both sides of the cart 1, and a cross plate 6 is provided at the upper end of the connecting plate 4, and a mounting plate 9 is provided at the lower end of the cross plate 6, and two groups of mounting plates 9 are provided, a paint brush roller 10 is rotatably connected to the mounting plate 9, and the paint brush roller 10 is provided with a plurality of paint brush rollers, and a paint spraying part 11 is provided on one side of the mounting plate 9, the guardrail is placed between the paint brush rollers 10, and the guardrail is driven to rotate at a uniform speed by controlling the rotation of the paint brush roller 10 Linear motion, during which the paint spraying part 11 sprays the guardrail. After the guardrail is sprayed with paint, the rolling paint roller 10 will uniformly roll and brush the guardrail to ensure that the paint on the guardrail can be evenly sprayed. A diversion pipe is fixed between the paint spraying part 11 and the extraction pump 3. An empty slot is opened in the mounting plate 9, and a gear 15 is arranged in the empty slot. The gear 15 is fixed to the rotating shaft of the paint roller 10, and a transmission belt 16 is meshed on the gear 15. A No. 2 motor 17 is fixed on the mounting plate 9, and the output shaft of the No. 2 motor 17 passes through the mounting plate 9 and is fixedly connected to one of the gears 15. The No. 2 motor 17 serves as a power source, which is convenient for controlling the rotational movement of the paint roller 10, and with the help of the gear 15 and the transmission belt 16, the single No. 2 motor 17 can control the simultaneous rotational movement of multiple paint rollers 10, thereby improving the utilization rate of the No. 2 motor 17.

[0021] Example 2

[0022] like Figure 1-4As shown, an electric telescopic rod 5 is embedded and fixed in the connecting plate 4, and one end of the electric telescopic rod 5 is fixedly connected to the cross plate 6. During normal spraying operation, the mounting plate 9 near the lower end is grounded. When the spraying is completed and the cart 1 needs to be pushed to move, the cross plate 6 is lifted as a whole by extending the electric telescopic rod 5, so that the mounting plate 9 at the lower end is separated from the ground to avoid wear during movement. A No. 1 motor 7 is fixed to one side of the cross plate 6, and a screw rod 8 is fixed to the output end of the No. 1 motor 7, and the screw rod 8 is rotatably connected to the cross plate 6.

With the help of the No. 1 motor 7 and the screw rod 8, one group of mounting plates 9 can be controlled to carry the paint roller 10 to move to change the two groups of paint rollers. The distance between 10 is convenient for adapting to guardrails of different widths and improving the practicability of the device. A fixing plate 12 is fixed on the surface of the mounting plate 9, and a slide rail column 13 is fixed on the surface of the fixing plate 12. The slide rail column 13 is slidably connected to the paint spraying part 11. In order to prevent the paint roller 10 from absorbing too much paint on its own surface when rolling the guardrail when it is dry, thereby reducing the adhesion of the guardrail paint, the paint roller 10 is generally wetted with paint in advance. With the help of the slide rail column 13, the paint spraying part 11 can be stably moved left and right to wet the paint roller 10. A plug-in 14 is fixedly connected to the surface of the fixing plate 12, and the plug-in 14 is engaged with the paint spraying part 11. The plug-in 14 is engaged and fixed to the paint spraying part 11, which improves the stability of the paint spraying part 11 when it is stationary and ensures the quality of subsequent painting.

[0023] Working principle:

[0024] like Figure 1-4 As shown, when the utility model is in use, the user first pushes the cart 1 to the specified position, then contracts the electric telescopic rod 5 in the connecting plate 4, so that the horizontal plate 6 drops as a whole, and the lower mounting plate 9 contacts the ground, and then starts the No. 2 motor 17 to drive the gear 15 and the transmission belt 16 to move, thereby driving the paint roller 10 to rotate, and then manually pushes the paint spraying part 11 to release the connection with the plug-in 14 and move along the slide rail column 13. During this period, the extraction pump 3 is turned on to extract the paint in the paint storage box 2 and spray it at the paint spraying part 11, and the rotating paint brush roller 10 is pre-moistened. After completion, the extraction pump 3 is turned off and the paint spraying part 11 is returned to its position, and the next step of spraying the guardrail is carried out.

[0025] Next, place one end of the guardrail between the two paint spraying parts 11 and contact it with the paint roller 10. Then, according to the width of the guardrail, start the No. 1 motor 7 to drive the screw 8 to rotate, and then control a group of mounting plates 9 to move, so as to change the distance between the two groups of paint rollers 10 to adapt the guardrail. After the adaptation is completed, restart the extraction pump 3 to allow the paint spraying part 11 to spray the guardrail. At the same time, the rotating paint roller 10 will drive the guardrail to move in a uniform straight line to ensure uniform spraying. After the guardrail is sprayed with paint, the rolling paint roller 10 will uniformly roll and brush the guardrail to further ensure the uniform distribution of paint on the guardrail.
