[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a paint spraying device for metal guardrail processing, comprising:

[0022] A paint spray box 1, wherein a switch door is installed on the paint spray box 1, which is not shown in the figure. In addition, a demisting device of the prior art is also installed on the paint spray box 1. The demisting device is a fan and a filter, which can remove the paint mist floating after the painting is completed, so that opening the switch door will not cause the paint mist to affect the staff;

[0023] A clamping assembly for adaptively clamping the guardrail; the clamping assembly includes two moving plates 9 that slide against the top of the spray box 1, and a conical block 10 is fixed on the opposite side of the two moving plates 9. A driving mechanism that makes the two moving plates 9 move synchronously is installed on the spray box 1. The driving mechanism includes a first screw rod 7 and a second screw rod 8 that are rotatably installed in the spray box 1. The first screw rod 7 and the second screw rod 8 are fixedly connected. A motor 2 is installed on the spray box 1, and the output end of the motor 2 is fixedly connected to the second screw rod 8. The first screw rod 7 and the second screw rod 8 respectively penetrate the same side. The movable plate 9 is threadedly connected with the movable plate 9, and the motor 2 drives the first screw 7 and the second screw 8 to rotate. Since the thread directions of the first screw 7 and the second screw 8 are set in opposite directions, and the movable plate 9 is limited by the paint spray box 1 and cannot rotate, the relative movement between the two movable plates 9 can be realized, and the distance between the two conical blocks 10 can be controlled, so that the conical blocks 10 are inserted into the steel pipes at both ends of the guardrail, so that the guardrail can be hung between the two conical blocks 10; due to the setting of the conical blocks 10, it can be applicable to the limit of various types of guardrail steel pipes, and the structure is simple and has good adaptability;

[0024] It also includes a paint spraying assembly that can move up and down; the paint spraying assembly includes a U-shaped tube 5 that moves up and down and is connected to the paint spraying equipment 3, an electric slide rail 4 is installed on the inner wall of the paint spraying box 1, an electric slider 12 slides on the electric slide rail 4, a connecting plate 11 is fixed on the electric slider 12, and the connecting plate 11 is fixedly connected to the U-shaped tube 5, and the electric slider 12 moves on the electric slide rail 4 to drive the connecting plate 11 and the U-shaped tube 5 to move up and down, thereby driving the spray head 13 to move up and down;

[0025] The upper end of the paint spray box 1 is equipped with a paint spraying device 3, the U-shaped tube 5 is connected to the paint spraying device 3 through a hose 6, the paint spraying device 3 includes a feed box and a feed pump, the hose 6 is connected to the feed pump, and the feed pump can transport the paint through the hose 6 to the U-shaped tube 5, and finally spray it out through the nozzle 13;

[0026] Among them, the U-shaped tube 5 can be sleeved on the outside of the movable plate 9 without contact, so the U-shaped tube 5 can be sleeved on the outside of the guardrail, the U-shaped tube 5 is inclined and a plurality of nozzles 13 are installed on the inner side of the U-shaped tube 5. Since the U-shaped tube 5 is inclined, the nozzles 13 on the U-shaped tube 5 will stagger the spraying of paint, so that the paint mist sprayed by the nozzles 13 will not affect each other; the U-shaped tube 5 is inclined and driven to move up and down, and the guardrail can be fully sprayed with paint through the nozzles 13 without rotating the guardrail, which can reduce the volume of the equipment;

[0027] Since the steel pipes at both ends of the lower side of the guardrail are not limited, they can be clamped and fixed by clamping into the steel pipes at both ends of the lower side, and then the motor 2 is reversed to make the conical block 10 detach from the guardrail. In this way, the painted guardrail can be removed without damaging the paint, and it can be transported to the drying equipment for drying; the shape of the guardrail can refer to the prior art CN217222035U.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
