[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example: Reference Figure 1-Figure 3 The device for automatically spraying rust preventive agent shown in the figure includes a hanging rail 1, a chute 11 is provided at the bottom of the hanging rail 1, a driving screw 3 is rotatably connected in the chute 11, a motor 2 is fixed to one side of the hanging rail 1 to drive the driving screw 3 to rotate, and a slide seat adapted to the driving screw 3 is also slidably connected in the chute 11;

[0028] An electric push rod 4 is fixed under the slide, and a nozzle 7 is provided at the lower end of the electric push rod 4. The nozzle 7 is connected to the lower end of the electric push rod 4 through a fixed seat 5 and a movable seat 6 so that the angle can be deflected;

[0029] A deflection assembly 9 for driving the movable seat 6 to deflect is also installed on the upper end of the movable seat 6, and a follower mechanism 8 for driving the deflection assembly 9 to rotate is installed on one side of the slide.

[0030] Based on the above structure, when in use, the motor 2 is started and the slide is driven by the lead screw 3 to slide in the slide groove 11, thereby driving the electric push rod 4, the fixed seat 5, the movable seat 6 and the nozzle 7 to move synchronously, so that the nozzle 7 moves back and forth in a straight line to perform horizontal coverage spraying on the workpiece. At the same time, the follower mechanism 8 drives the deflection component 9 to rotate during the movement. When the deflection component 9 rotates, the movable seat 6 is deflected, thereby causing the nozzle 7 to deflect and form a circular deflection path. Combined with its own linear motion, a wider longitudinal coverage range is formed, so that a single nozzle 7 can meet the spraying needs of a larger area of ​​workpieces during one movement, achieve a better spraying effect, and improve the spraying efficiency.

[0031] Furthermore, the upper end of the fixed seat 5 is fixed to the lower end of the piston rod of the electric push rod 4, the lower end of the movable seat 6 is fixed to the upper end of the nozzle 7, and the upper end of the movable seat 6 is embedded with a ball 61, and the upper end of the ball 61 is fixed to the lower end of the fixed seat 5 through a connecting column 62;

[0032] By setting the rolling ball 61 and the connecting column 62, the movable seat 6 can be movably connected to the fixed seat 5, and the movable seat 6 can produce a deflection along the center of the rolling ball 61, and the deflection is carried out around the axis of the connecting column 62 and forms a circular motion trajectory, thereby meeting the deflection requirements of the nozzle 7.

[0033] Furthermore, the deflection assembly 9 includes:

[0034] The rotating ring 91 is rotatably connected to the fixed seat 5 through a connecting structure. The rotating ring 91 is arranged above the movable seat 6, and the inner diameter of the rotating ring 91 is larger than the diameter of the movable seat 6;

[0035] A connecting block 92, one end of which is fixed to the lower end of the rotating ring 91, and the other end of which extends above the movable seat 6;

[0036] The upper end of the column 93 is fixed to the connecting block 92 , and the lower end of the column 93 abuts against the upper end of the movable seat 6 , so that the movable seat 6 deflects along the center of the connecting column 62 .

[0037] A rack 12 is fixedly embedded in one side of the chute 11;

[0038] The follower mechanism 8 includes a driven gear 81, a transmission shaft 82 and a driving wheel 83. The driven gear 81 is rotatably connected to one side of the slide through a connecting rod. The driven gear 81 is engaged with the rack 12. The upper end of the transmission shaft 82 is fixed to the driven gear 81. The driving wheel 83 is fixedly sleeved on the lower end of the transmission shaft 82. One side of the driving wheel 83 is in transmission contact with the outer side of the rotating ring 91.

[0039] When the slide seat slides, it drives the driven gear 81 to slide synchronously. When the driven gear 81 slides, it engages with the rack 12 to rotate, and drives the driving wheel 83 to rotate through the transmission shaft 82. When the driving wheel 83 rotates, it drives the rotating ring 91 to rotate, thereby causing the support column 93 to rotate accordingly. Since the support column 93 presses down and tilts one side of the movable seat 6, the support column 93 drives the movable seat 6 to deflect during the rotation process, thereby achieving the purpose of driving the nozzle 7 to deflect.

[0040] Furthermore, wing plates 831 are formed at the upper and lower ends of the driving wheel 83, and the gap between the two wing plates 831 is clamped at the upper and lower ends of the rotating ring 91. The transmission shaft 82 is a retractable shaft, for example, a square rod and a sleeve rod structure with a square hole (not shown in the figure) are used. The square rod and the sleeve rod are connected to achieve a telescopic transmission effect. The setting of the wing plates 831 enables the driving wheel 83 to be raised and lowered synchronously when the rotating ring 91 is raised and lowered, maintaining good transmission between the two. In this way, when the nozzle 7 is driven by the electric push rod 4 to change the distance between it and the workpiece, the follow-up mechanism 8 can still stably drive the rotating ring 91 to rotate, thereby achieving a driving effect during the movement.

[0041] Furthermore, the connection structure includes a fixing rod 94 and a connecting ring 95. The connecting ring 95 is rotatably mounted on the fixing seat 5. The two ends of the fixing rod 94 are respectively fixed to the outer side of the connecting ring 95 and the inner side of the rotating ring 91, which can meet the rotation requirements of the rotating ring 91 and make its connection stable.

[0042] The working principle of the present invention is as follows: in daily use, after the motor 2 is started, the slide is driven by the lead screw 3 to slide in the slide groove 11, thereby driving the electric push rod 4, the fixed seat 5, the movable seat 6 and the nozzle 7 to move synchronously, so that the nozzle 7 moves back and forth in a straight line to spray the workpiece horizontally. When the slide slides, it drives the driven gear 81 to slide synchronously. When the driven gear 81 slides, it engages with the rack 12 to rotate, and drives the driving wheel 83 to rotate accordingly through the transmission shaft 82. When the driving wheel 83 rotates, it drives the rotating ring 91 to rotate, so that the support column 93 rotates accordingly. Because the support column 93 presses down and tilts one side of the movable seat 6, the support column 93 drives the movable seat 6 to deflect during the rotation process, thereby causing the nozzle 7 to deflect and form a circular deflection path. Combined with its own linear motion, a wider longitudinal coverage range is formed, so that a single nozzle 7 can meet the spraying needs of a larger area of ​​workpieces during one movement, achieve better spraying effects, and improve spraying efficiency.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
