Detailed Implementation

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] The nozzle device of this utility model, such as Figures 1 to 4 As shown, it includes an oil spray head 31 for spraying oil onto the rear side 991 of the sheet metal and an oil suction head 32 for abutting against the rear side 991 of the sheet metal. The oil spray head 31 is slidably arranged relative to the oil suction head 32. Specifically, the oil spray head 31 can be connected to a bracket via a linear guide rail, while the oil suction head 32 can be fixedly connected to the bracket. The oil spray head 31 is located to the right of the oil suction head 32. Since the sheet metal 99 moves from right to left, a right side surface 3201 is formed on the right side of the oil suction head 32. An oil return groove 321 is formed on the right side surface 3201, and a groove opening 3210 is formed at the right end of the oil return groove 321. In other words, the oil return groove 321 is set to open to the right, and the front end of the oil return groove 321 passes through the oil suction head 32. Figure 2 As shown, this forms the front opening 3211 of the groove. The rear end of the oil return groove 321 is connected to the first oil return channel 323. In other words, the first oil return channel 323 is formed inside the oil suction head 32. The oil injection head 31 has a left side surface 3101, which is a vertical plane. The left side surface 3101 is attached to the right side surface 3201 of the oil suction head. The front end of the oil injection head 31 has an oil injection port 311. Figure 2 and Figure 3 As shown, the top of the fuel injector 31 has a fuel inlet 312, and the lower part of the fuel inlet 312 connects to the fuel injector 311, through which fuel is input into the fuel injector 31. The fuel injector 31 has a front position and a rear position relative to the fuel suction head 32; as shown... Figure 2 and Figure 3As shown, in the above-mentioned front position, the left side surface 3101 of the oil injection head 31 closes the groove opening 3210, specifically, the front end surface of the oil injection head 31 is flush with the front end surface of the oil suction head 32; in the above-mentioned rear position, as shown in Figure 4 As shown, the left side surface 3101 of the oil injection head 31 opens the groove opening 3210, that is to say, the left side surface 3101 of the oil injection head 31 moves rearward to open the groove opening 3210. As shown in Figure 2 As shown, the rear end of the first oil return channel 323 is communicated with the oil return pipe 33, in other words, the front groove opening 3211 is communicated with the first oil return channel 323, and the rear end of the oil return pipe 33 is used to connect a vacuum pump.

[0020] As shown in Figure 5 As shown, the oil injection head 31 is moved forward to the above-mentioned front position, and the oil injection port 311 of the oil injection head 31 abuts against the rear side surface 991 of the plate, and the oil injection port 311 sprays oil to the rear side surface 991 of the plate, so that the oil injection head 31 starts to spray and form a spraying area on the rear side surface 991 of the plate, and as the plate 99 moves leftward, the oil just sprayed on the rear side surface 991 of the plate moves to the front groove opening 3211, and the front groove opening 3211 absorbs the excess oil through negative pressure; as shown in Figure 6 As shown, when a spraying area is sprayed, the oil injection head 31 is moved rearward to the above-mentioned rear position, during which the groove opening 3210 is gradually opened, and as the rear end of the oil return groove 321 is connected with the first oil return channel 323, the rear end of the oil return groove 321 forms negative pressure, and when the oil injection port 311 leaves the rear side surface 991 of the plate, the oil sprayed by the oil injection port 311 can be immediately absorbed by the front groove opening 3211 and the oil return groove 321, which is equivalent to that the oil injection head 31 is moved rearward while the oil suction opening range of the oil suction head 32 is increased, so as to avoid the accumulation of oil at the front right end of the oil suction head 32, thereby avoiding the obvious dragging of the excess oil at the end of the spraying area, which is beneficial to the neatness of the end of the spraying area, in other words, which is beneficial to the effective and rapid stop of the intermittent spraying; as the spraying range of the oil sprayed by the oil injection port 311 is short, when the oil injection port 311 is moved rearward to the above-mentioned rear position, the oil sprayed by the oil injection port 311 will not be splashed on the plate 99; and the oil return groove 321 can effectively recover the oil sprayed by the oil injection port 311 during the subsequent rearward movement of the oil injection port 311, which is beneficial to the rapid recovery of the oil (i.e. beneficial to the rapid oil return). When the oil injection port 311 is moved forward again to abut against the plate 99, the next spraying area can be sprayed. As can be seen from the above, by setting the oil injection head 31 to be movable forward and rearward relative to the oil suction head 32, the intermittent spraying of the same plate 99 can be effectively realized, the oil suction head 32 can be kept abutting against the rear side surface 991 of the plate, so that the function of absorbing excess oil is effectively and continuously maintained, and by setting the above-mentioned oil return groove 321 structure, the neatness of the end of the spraying area is improved, that is to say, the intermittent spraying effect is improved.

[0021] Further, as shown in Figure 2As shown, the oil suction head 32 forms a second oil return channel 322, and an oil suction port 3221 is formed at the front end of the second oil return channel 322. The second oil return channel 322 is located on the left side of the oil return groove 321. Thus, the oil suction port 3221 enhances the absorption of excess oil. That is to say, most of the excess oil on the rear side 991 of the board is absorbed by the front opening 3211 of the groove. The excess oil on the rear side 991 of the board then moves to the left to the oil suction port 3221. The oil suction port 3221 further absorbs the excess oil, which helps to form a uniform paint layer after the oil on the rear side 991 of the board dries and also helps to save oil.

[0022] Furthermore, such as Figure 2 As shown, the second oil return channel 322 is arranged from back to front, gradually approaching the right side 3201 of the oil suction head. In other words, the second oil return channel 322 forms an acute angle with the right side 3201 of the oil suction head. Figure 5 As shown, because the oil on the rear side 991 of the plate moves to the left, when the excess oil is absorbed by the oil suction port 3221 and leaves the rear side 991 of the plate, due to inertia, the excess oil will still tend to move to the left. With the above setting, the second return oil channel 322 is tilted to meet the excess oil, so that the excess oil can enter the second return oil channel 322 faster and more smoothly.

[0023] Furthermore, such as Figure 5 As shown, the second oil return channel 322 can be parallel to the first oil return channel 323. Since the oil return groove 321 is formed on the right side 3201 of the oil suction head, the front end of the first oil return channel 323 needs to be arranged close to the right side 3201 of the oil suction head. Since the first oil return channel 323 is parallel to the second oil return channel 322, the first oil return channel 323 gradually moves away from the right side 3201 of the oil suction head from front to back, which can avoid damage to the right side 3201 of the oil suction head when the first oil return channel 323 is formed.

[0024] Furthermore, such as Figures 1 to 3 As shown, the nozzle device of this utility model also includes an oil suction head support 35. The rear end of the oil suction head 32 is mounted and connected to the oil suction head support 35. Specifically, the rear end of the oil suction head 32 has mounting ears formed at the top and bottom, respectively. The mounting ears are mounted and connected to the oil suction head support 35 by corresponding screws. Figure 2 As shown, the fuel injector 31 is located on the front side of the fuel suction head support 35; as Figure 6 As shown, in the aforementioned rear position, the rear end of the fuel injector 31 is attached to the fuel suction head support 35. In other words, the fuel suction head support 35 limits the fuel injector 31. At this time, the fuel injector 311 does not extend backward beyond the groove 3210, so the oil sprayed from the fuel injector 311 can be effectively recovered by the groove 3210.

[0025] like Figure 2As shown, the front end of the oil return pipe 33 is provided with a flange structure, which is mounted and connected to the rear side of the oil suction head support 35. The oil suction head support 35 is formed with an oil passage hole 351, which connects the rear end of the second oil return channel 322 and the rear end of the first oil return channel 323 to the oil return pipe 33. Figure 1 and Figure 3 As shown, the spray head device further comprises an oil injection head support 34. The upper end of the oil injection head support 34 is mounted with a cantilever beam 341. The upper end of the oil injection head 31 is mounted and connected to the left end of the cantilever beam 341. The oil injection head support 34 is arranged at the right side of the oil suction head support 35. For example, the oil injection head support 34 can be slidably connected to the above-mentioned support through a linear guide rail. A servo motor can be used to drive the oil injection head support 34 to move forward and backward through a ball screw pair. Alternatively, a cylinder can be used to drive the oil injection head support 34 to move forward and backward.
