[0031] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0032] Embodiment 1: In order to solve the problem that in the prior art, the sprayer needs to be manually controlled during the spraying process, there is a time difference between the manual control and the actual spraying situation, resulting in paint waste, the following technical solution is disclosed, see Figure 1-Figure 3 As shown, a fine environmentally friendly automatic spraying machine includes a connecting pipe 12, which is fixed at the lower part of the spraying device 1, and a fixed pipe 7 is fixed at the left end of the inside of the spraying device 1;

[0033] The hose 3 is connected to the upper and lower sides of the right end of the fixed pipe 7, and the nozzle 2 is fixed to the right end of the upper hose 3, and the lower hose 3 is installed together with the upper end of the connecting pipe 12;

[0034] The electronic spray gun 11 is arranged inside the connecting pipe 12; the placing plate 9 is rotatably connected inside the spraying device 1, and a fine mechanism is arranged at the lower end of the placing plate 9. By changing the spacing to control the electronic spray gun 11, the waste of spraying paint can be reduced and the function of environmental protection can be achieved; the fine mechanism includes an electronic sensor 18, which is welded to the upper end of the fixing frame 19, and the electronic sensor 18 controls the normal operation of the electronic spray gun 11, and the lower end of the fixing frame 19 is welded to the upper right end of the fixing rod 4 below; the lower end of the shaft of the placing plate 9 is provided with a ratchet assembly 15, and the outer side of the ratchet assembly 15 is penetrated and fixed with a rotating frame 14, and a motor 10 is welded at the lower part of the spraying device 1, and the output end of the motor 10 is fixed to the lower end of the ratchet assembly 15;

[0035] The lower end of the placement plate 9 is adhered with a furry Velcro 13, and the lower end of the furry Velcro 13 contacts with a thorny Velcro 16, and the lower end of the thorny Velcro 16 is adhered with a bump 17;

[0036] Place the object to be sprayed on the placement plate 9, fix the object by the limiting structure on the placement plate 9, turn the rotating frame 14 clockwise by hand, the rotating frame 14 rotates clockwise to drive the ratchet assembly 15, the ratchet assembly 15 rotates clockwise to drive the placement plate 9 to rotate, avoid the place where the spraying is located directly above the electronic sensor 18, according to the required spraying position and spraying shape, place the corresponding shape of the protrusion 17 on the wool Velcro 13 through the thorn Velcro 16, so that the place where the object needs to be sprayed is aligned with the protrusion 17 up and down, the motor 10 runs to make the ratchet assembly 15 rotate clockwise, the rotation of the ratchet assembly 15 drives the placement plate 9 to rotate, the rotation of the placement plate 9 drives the protrusion 17 to rotate synchronously, when the protrusion 17 rotates to the electronic sensor 18, the electronic sensor 18 sends the received signal to the electronic spray gun 11, and the electronic sensor 18 makes the electronic spray gun 11 work. The electronic spray gun 11 works to make the spray material below the inside of the spraying equipment 1 be sprayed out through the connecting pipe 12, the fixed pipe 7, the hose 3 and the nozzle 2, and the nozzle 2 sprays the material above. When the protrusion 17 rotates to separate from the electronic sensor 18, the electronic sensor 18 sends a new signal to the electronic spray gun 11 again, and the electronic spray gun 11 stops running immediately. The electronic spray gun 11 can be accurately controlled by the electronic sensor 18 to avoid excessive spraying, so as to achieve the purpose of fine painting, reduce the waste of paint, and thus reduce the waste of resources.

[0039] The upper threaded rod 5 is rotated by hand. The upper threaded rod 5 drives the pulley assembly 6 to rotate during the rotation. The pulley assembly 6 drives the lower threaded rod 5 to rotate, so that the upper and lower threaded rods 5 rotate synchronously. The rotation of the threaded rod 5 causes the fixed rod 4 to move left and right. During the movement of the upper and lower fixed rods 4, the spray head 2 and the electronic sensor 18 are driven to move synchronously respectively, so that the spray head 2 and the electronic sensor 18 are always aligned, and the spray head 2 and the electronic sensor 18 are moved to the position of spraying the object;

[0040] Embodiment 3: This embodiment prevents the objects above the placement plate 9 from sliding during the rotation process.

[0042] When the object is placed in the middle above the placement plate 9, the cover plate 8 is then rotated by hand, and the placement plate 9 is supported and fixed by the other hand. The cover plate 8 moves up and down synchronously during the rotation. The cover plate 8 moves downward to push the knocking rod 20, so that the knocking rod 20 rotates to the middle position. The knocking rod 20 rotates to push the limit block 22, and the limit blocks 22 around move synchronously. When the cover plate 8 cannot rotate, it means that the knocking rod 20, the limit block 22 and the object are in contact in turn, and the limit block 22 fits the outer side of the object, thereby achieving the fixation of the object.

[0043] The spray machine has the function of automatically recording the ledger, which records the spraying amount and displays it on the display screen to achieve refined environmental management. A monitoring and alarm system is set inside the spray machine. The monitoring and alarm system monitors the paint spraying quality in real time and can compare the actual paint spraying quality with the target value range to determine whether the actual spraying amount exceeds the limit. If the spraying amount is within the target range, the spraying process meets the quality requirements and the casting spraying quality is qualified. If the spraying amount exceeds the limit, an alarm signal is output and the casting is scrapped. If the spraying amount continues to exceed the limit, consider overhauling the equipment.
