DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a reciprocating coating machine includes a frame 20, a rotating motor 21 is fixedly connected to the side wall of the frame 20, a sliding rod 22 is fixedly connected to the top of the frame 20, a spray head 23 is slidably connected to the wall of the sliding rod 22, a servo motor 24 is fixedly connected to the front wall of the spray head 23, the rotating motor 21 and the servo motor 24 are both electrically connected to corresponding power sources, the spray head 23 can be connected to the coating machine, and the spray head 23 can spray the paint in the coating machine. This is an existing technology, so it will not be described here.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the wall of the frame 20 is provided with a clamping structure, the clamping structure includes a chuck 31 and a clamping block 36, the chuck 31 is rotatably connected to the wall of the frame 20, the clamping block 36 is elastically connected to the wall of the chuck 31, the clamping structure also includes a spring groove 32, a stop block 33 and a stop block 34, the spring groove 32 is opened on the wall of the chuck 31, the stop block 33 is fixedly connected in the spring groove 32, and the stop block 34 is also fixedly connected in the spring groove 32. Four spring grooves 32 are opened on the wall of the chuck 31, and the four spring grooves 32 are connected on the wall of the chuck 31 to form a cross shape. The cross-section of the spring groove 32 is an inverted T-shaped groove. The number of the stop blocks 33 is consistent with the spring grooves 32, each stop block 33 is fixedly connected to the end in the spring groove 32, and the stop block 34 is fixedly connected at the center position between all the spring grooves 32. The clamping structure can fix the workpiece on the wall of the frame 20.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the cross section of the clamping block 36 is an isosceles triangle, four clamping blocks 36 are arranged on the wall of the chuck 31, and the four clamping blocks 36 are distributed in a circular array on the wall of the chuck 31. The racks 20 and the rotating motor 21 are symmetrically arranged on both sides of the slide bar 22. The chuck 31 is arranged between the symmetrical racks 20. The cross section of the chuck 31 is circular. The clamping structure also includes a spring block 35 and a suction cup 37. The spring block 35 is elastically connected in the spring groove 32, and the suction cup 37 is fixedly connected to the top of the clamping block 36. The cross section of the spring block 35 is an inverted T-shape, and the bottom of the clamping block 36 is fixedly connected to the top of the spring block 35. The cavity of the spray head 23 is hollow, and the cavity of the spray head 23 is rotatably connected with a roller 25. The servo motor 24 can pass through the spray head 23 and connect with the roller 25. The wall of the roller 25 can contact the slide bar 22, and the spray head 23 slides on the wall of the slide bar 22.

[0027] When in use, the workpiece to be coated is manually placed between the symmetrical clamping plates 31. At this time, the retractable extension rod 30 is controlled to retract to adapt to the width of the workpiece. After the width is adapted, if there are protrusions that can be clamped on both sides of the workpiece, multiple clamping blocks 36 can clamp the protrusions that can be clamped, and the spring block 35 is connected by a spring stop block 33. The spring can push the spring block 35 to move toward the stop block 34 so that the protrusion that can be clamped is clamped between the multiple clamping blocks 36. If the wall surface of the workpiece is smooth, the suction cup 37 can absorb the wall surface to complete the fixation. After the workpiece is fixed, the power is turned on. At this time, the servo motor 24 can drive the roller 25 to rotate, thereby driving the spray head 23 to slide back and forth along the slide rod 22. When the spray head 23 slides, the paint will be sprayed from the bottom of the spray head 23 to the wall surface of the workpiece. At this time, the rotating motor 21 can drive the extension rod 30 to rotate, thereby driving the workpiece to rotate, so that the upper and lower front and rear walls of the workpiece are evenly sprayed with paint;

[0028] In summary, by setting up a clamping structure, workpieces of different sizes and shapes can be fixed between the frames 20 so that they can be evenly sprayed, because the clamping structure adapts to and fixes workpieces of different sizes through the movable clamping block 36 and the suction cup 37 that can adsorb, and the extension rod 30 can also adapt to the width of the workpiece by contraction, so compared with the prior art, the scope of application of this solution is wider.

[0029] like Figure 1 and Figure 2 As shown, the wall surface of the rotating motor 21 is also fixedly connected with an anti-spill shell 38, the cavity of the anti-spill shell 38 is hollow, and all the clamping structures are in the cavity of the anti-spill shell 38;

[0030] When in use, the front wall of the anti-spill shell 38 can be opened manually, and the front wall of the anti-spill shell 38 is in the shape of transparent glass;

[0031] In summary, by setting up the anti-spill shell 38, it is possible to prevent paint from splashing to the surroundings when the workpiece is painted, because the anti-spill shell 38 prevents paint from splashing by wrapping the workpiece in its cavity, and the staff can observe the spraying situation of the workpiece in the cavity of the anti-spill shell 38 through the front wall of the anti-spill shell 38, so the anti-spill shell 38 can increase the environmental friendliness of the device and prevent paint from polluting the environment during spraying.

[0032] Working principle: manually place the workpiece to be painted between the symmetrical chucks 31, and then control the retractable extension rod 30 to retract to adapt to the width of the workpiece. After the width is adapted, if the workpiece has protrusions that can be clamped on both sides, multiple clamping blocks 36 can clamp the protrusions that can be clamped, and the spring block 35 is connected by a spring stop block 33. The spring can push the spring block 35 to move toward the stop block 34, so that the protrusion that can be clamped is clamped between the multiple clamping blocks 36. If the wall surface of the workpiece is smooth, the suction cup 37 can adsorb the wall surface to complete the fixation. After the workpiece is fixed, the power is turned on. At this time, the servo motor 24 can drive the roller 25 to rotate, thereby driving the spray head 23 to slide back and forth along the slide bar 22. When the spray head 23 slides, the paint will be sprayed from the bottom of the spray head 23 to the wall surface of the workpiece. At this time, the rotating motor 21 can drive the extension rod 30 to rotate, thereby driving the workpiece to rotate, so that the upper and lower front and rear walls of the workpiece are evenly sprayed with paint.
