[0036] like Figure 1-Figure 5As shown, a plastic parts painting equipment according to an embodiment of the present invention includes a base 8: a spray booth shell 11 fixedly connected to the top of the base 8; an observation window 5 fixedly connected to the middle of the rear side of the spray booth shell 11; a first connecting shaft 4 fixedly connected to the rear of the left side of the spray booth shell 11; a first door panel 6 rotatably connected to the rear side of the first connecting shaft 4, and the first door panel 6 passes through the spray booth shell 11; a threaded rod 36 passes through and is rotatably connected to the middle part of the inner part of the base 8, a first slider 34 passes through and is threadedly connected to the rear part of the outer ring of the threaded rod 36, and the first slider 34 passes through and is slidably connected to the base 8, a rotating rod 28 passes through and is rotatably connected to the middle part of the top of the first slider 34, a gear 32 passes through and is fixedly connected to the lower part of the outer ring of the rotating rod 28, a rack 30 is fixedly connected to the right side of the top of the base 8, and the rack 30 is meshed with the gear 32, a limit rod 29 passes through and is fixedly connected to the left and right sides of the inner part of the base 8, and a second slider 33 passes through and is slidably connected to the rear part of the outer ring of the limit rod 29 , and the second slider 33 passes through and is slidably connected to the base 8, a connecting plate 35 is fixedly connected between the tops of the second sliders 33, a turntable 26 is fixedly connected to the top of the rotating rod 28, and a uniformly distributed fixing fixture 25 is fixedly connected to the top of the turntable 26, and two rotating joints 22 are fixedly connected to the top rear of the spray booth shell 11, and the lower port of the rotating joint 22 passes through and is fixedly connected to the nozzle 23, and a second delivery pipe 3 is fixedly connected between the upper ports of the rotating joint 22, and the other end of the second delivery pipe 3 passes through and is fixedly connected to the liquid pump 19, and the liquid pump 19 is fixedly connected to the spray booth shell 11, the input end of the liquid pump 19 passes through and is fixedly connected to the first delivery pipe 1, and the other end of the first delivery pipe 1 passes through and is fixedly connected to the storage tank 2, and the storage tank 2 is fixedly connected to the spray booth shell 11, a deflection assembly is arranged on the rear side of the interior of the spray booth shell 11, an air intake mechanism is arranged on the left front of the spray booth shell 11, and an exhaust mechanism is arranged on the right front of the spray booth shell 11.

[0037] Under the prior art, the plastic parts fixing structure and the angle of the nozzle of the general spraying equipment are mostly fixed. For plastic parts with diverse appearances, the spraying process will cause uneven paint surface, affecting the subsequent processing flow, and ultimately affecting the quality of the product. As an embodiment of the present invention, when starting to spray the plastic parts, first open the first door panel 6, and fix the plastic parts on the turntable 26 through the fixing clamp 25. By turning on the liquid pump 19, the paint liquid in the storage tank 2 is transported to the nozzle 23 through the first delivery pipe 1, the second delivery pipe 3 and the rotary joint 22, and the plastic parts are started to be sprayed. At the same time, the drive motor 18 is turned on to drive the thread The rod 36 rotates, and then in cooperation with the first slider 34, the rotational motion is converted into linear motion, driving the first slider 34 to move forward, and the rotating rod 28 moves with the first slider 34, and in cooperation with the gear 32 and the rack 30, the rotating rod 28 starts to rotate, thereby driving the turntable 26 and the plastic parts fixed on the turntable 26 to rotate, and at the same time cooperates with the spray head 23 to spray the surface of the plastic parts, so that the surface of the plastic parts is sprayed evenly, wherein the limiting rod 29 limits the first slider 34 through the connection between the second slider 33 and the connecting plate 35 to prevent it from deflecting, and at the same time makes the movement process of the first slider 34 smoother.

[0038] like Figure 4 As shown, the deflection assembly includes a connecting rod 24, which is fixedly connected to the nozzle 23, and the connecting rod 24 passes through and is rotatably connected to the paint spray booth housing 11, a steering rod 31 passes through and is fixedly connected to the lower part of the outer ring of the connecting rod 24, a toggle ring 27 is provided on the upper side of the gear 32, and the toggle ring 27 passes through and is rotatably connected to the rotating rod 28, the toggle ring 27 is fixedly connected to the connecting plate 35, the steering rod 31 corresponds to the toggle ring 27, and blocking plates 45 are provided on the front and rear sides of the steering rod 31, and the blocking plates 45 are fixedly connected to the paint spray booth housing 11, and the blocking plates 45 correspond to the steering rod 31.

[0039] When the deflection assembly provided by the present invention is in use, when the rotating rod 28 continues to move forward, the toggle ring 27 moves forward with the rotating rod 28, and contacts and squeezes the steering rod 31, and by squeezing the steering rod 31, the connecting rod 24 is driven to deflect, thereby driving the spray head 23 to deflect, so that the spray head angle of the spray head 23 is always aligned with the plastic part. When the steering rod 31 deflects and contacts the front blocking plate 45, the steering rod 31 will be restricted from deflection, and the toggle ring 27 continues to move forward, squeezes and separates from the steering rod 31. In the initial state, there is a certain distance between the toggle ring 27 and the steering rod 31. In the early stage of the spraying process, the front of the plastic part is sprayed using this distance. When the toggle ring 27 contacts and opens When the toggle ring 27 starts to drive the steering rod 31 to deflect, the nozzle 23 starts to spray the middle part of the plastic part. When the toggle ring 27 is separated from the steering rod 31, the nozzle 23 starts to spray the rear part of the plastic part, and at the same time cooperates with the gear 32 and the rack 30 to drive the plastic part to rotate, thereby achieving uniform spraying of the plastic part. Among them, the front end of the steering rod 31 is made of a material with a certain elastic deformation. After the steering rod 31 contacts the blocking plate 45, the toggle ring 27 squeezes and causes the steering rod 31 to produce elastic deformation, thereby separating from the steering rod 31. The blocking plate 45 is a slope plate, so that when the steering rod 31 contacts the blocking plate 45, the deflection of the steering rod 31 is restricted while avoiding damage to the steering rod 31.

[0040] like Figure 6 and Figure 7 As shown, the air intake mechanism includes an air intake chamber shell 14, which is fixedly connected to the paint spray booth shell 11, a heating net 37 is penetrated and arranged on one side of the air intake chamber shell 14 adjacent to the base, and the heating net 37 penetrates and is fixedly connected to the paint spray booth shell 11, a first protective net 38 is penetrated and fixedly connected on the front side of the air intake chamber shell 14, a first bearing 44 is penetrated and fixedly connected on the middle part of the front side of the first protective net 38, an air intake fan blade 40 is penetrated and fixedly connected on the middle part of the front side of the first bearing 44, a first driven pulley 15 is penetrated and fixedly connected on the front end of the air intake fan blade 40, a first driving pulley 39 is fixedly connected on the front end of the threaded rod 36, and a first belt 16 is sleeved between the outer rings of the first driven pulley 15 and the first driving pulley 39.

[0041] When the air intake mechanism provided by the present invention is in use, while the driving motor 18 drives the threaded rod 36 to rotate, the threaded rod 36 drives the first active pulley 39 to start rotating, and through the conduction of the first belt 16, drives the first driven pulley 15 to start rotating, and then drives the air intake blades 40 to start rotating in cooperation with the first bearing 44. The rotation of the air intake blades 40 will draw external air into the interior of the air intake chamber shell 14, and the air passes through the heating net 37 and is heated. Then the hot air enters the interior of the paint spray room shell 11, and the hot air is used to dry the paint surface on the outer surface of the plastic part. The first protective net 38 can prevent external environmental factors from damaging the air intake blades 40, and the setting of the first bearing 44 can make the rotation of the air intake blades 40 smoother and more stable.

[0042] like Figure 6 and Figure 7 As shown, the exhaust mechanism includes an exhaust chamber shell 20, which is fixedly connected to the paint spray booth shell 11, a second protective net 46 penetrates and is fixedly connected to the middle of the front side of the exhaust chamber shell 20, a second bearing 47 penetrates and is fixedly connected to the middle of the front side of the second protective net 46, an exhaust fan blade 9 penetrates and is fixedly connected to the middle of the front side of the second bearing 47, a second driven pulley 41 penetrates and is fixedly connected to the front end of the exhaust fan blade 9, a second driving pulley 43 penetrates and is fixedly connected to the front end of the threaded rod 36, and a second belt 42 is sleeved between the outer rings of the second driving pulley 43 and the second driven pulley 41.

[0043] When the exhaust mechanism provided by the present invention is in use, while the driving motor 18 drives the threaded rod 36 to rotate, the threaded rod 36 drives the second active pulley 43 to rotate, and drives the second driven pulley 41 to rotate under the conduction with the second belt 42, and then drives the exhaust fan blades 9 to start rotating in cooperation with the second bearing 47. Under the action of the exhaust fan blades 9, the air inside the paint spray room shell 11 is first drawn into the exhaust chamber shell 20, and then discharged from the exhaust chamber shell 20 to the external environment, wherein the second protective net 46 can prevent external environmental factors from damaging the exhaust fan blades 9, and the setting of the second bearing 47 can make the exhaust fan blades 9 rotate more smoothly and stably.

[0044] like Figure 6 As shown, a first filter screen 12 penetrates and is slidably connected to the middle of the left side of the air inlet chamber housing 14 , and the first filter screen 12 corresponds to the air inlet fan blade 40 .

[0045] When the first filter screen 12 provided by the present invention is in use, when air enters the air inlet chamber housing 14 , the air first passes through the first filter screen 12 , and the dust and impurities therein are filtered out by the first filter screen 12 .

[0046] like Figure 6As shown, a second filter screen 21 penetrates and is slidably connected to the middle of the right side of the exhaust chamber housing 20 , and the second filter screen 21 corresponds to the exhaust fan blade 9 .

[0047] When the second filter 21 provided by the present invention is in use, when the air inside the paint spray booth shell 11 is extracted to the external environment, the paint liquid mixed air generated during the spraying process will pass through the second filter 21, and the paint liquid particles will be filtered out by the second filter 21, reducing the pollution of the paint liquid particles to the environment.

[0048] like Figure 2 and Figure 3 As shown, a second handle 13 is fixedly connected to the middle of the left side of the first filter screen 12 and the middle of the right side of the second filter screen 21 .

[0049] When the second handle 13 provided by the present invention is in use, when the first filter 12 and the second filter 21 need to be cleaned or replaced, the first filter 12 and the second filter 21 are pulled out from the air inlet chamber shell 14 and the exhaust chamber shell 20 through the second handle 13 .

[0050] like Figure 2 As shown, a second connecting shaft 10 is fixedly connected to the front side of the top of the spray booth shell 11 , a second door panel 48 is fixedly connected to the lower front part of the second connecting shaft 10 , and a third handle 49 is fixedly connected to the lower front part of the second door panel 48 .

[0051] When the second door panel 48 provided by the present invention is in use, after the plastic parts are sprayed and dried, the second door panel 48 is opened by pulling the third handle 49 to take out the processed plastic parts.

[0052] like Figure 2 As shown, a protective cover 17 is fixedly connected to the middle of the front side of the base 8, and the first belt 16 and the second belt 42 both pass through the protective cover 17. A driving motor 18 is fixedly connected to the front side of the protective cover 17, and the output end of the driving motor 18 passes through and is fixedly connected to the threaded rod 36.

[0053] When the protective cover 17 provided by the present invention is in use, the first driving pulley 39 and the second driving pulley 43 are protected by the protective cover 17 to prevent interference from the external environment, and the threaded rod 36 is driven to rotate by the driving motor 18 .

[0054] like Figure 1 As shown, a first handle 7 is fixedly connected to the left rear portion of the first door panel 6 .

[0055] When the first handle 7 provided by the present invention is in use, the first door panel 6 is opened by pulling the first handle 7 .

[0056] Working principle: When it is necessary to spray paint on the plastic part, first open the first door panel 6 by pulling the first handle 7, then fix the plastic part on the turntable 26 by the fixing clamp 25, and then close the first door panel 6 to start the liquid pump 19 and the drive motor 18. Under the action of the liquid pump 19, the liquid paint stored in the storage tank 2 is pumped out, passes through the first delivery pipe 1 and the second delivery pipe 3 into the interior of the rotary joint 22, and finally reaches the nozzle 23 and is sprayed out through the nozzle 23 to spray paint on the surface of the plastic part. At the same time, under the action of the drive motor 18, the threaded rod 36 is driven to rotate, and the first slider 34 is driven to move forward in cooperation with the first slider 34. During the movement, the gear 32 and the rack 30 are relative. Under the cooperation, the rotating rod 28 starts to rotate, and then the turntable 26 and the plastic parts fixed on the turntable 26 start to rotate, and the plastic parts are sprayed while being rotated. When the toggle ring 27 moves to contact and begin to squeeze the steering rod 31, it starts to drive the steering rod 31 to deviate in angle, and then the connecting rod 24 is driven to rotate through the steering rod 31, thereby driving the nozzle 23 to change its angle. The angle of the nozzle 23 changes continuously with the continuous movement of the toggle ring 27, so that the nozzle position of the nozzle 23 is always aligned with the plastic parts. When the toggle ring 27 drives the steering rod 31 to deflect to a certain angle, the steering rod 31 will be stuck in the extreme position by the blocking plate 45 and will no longer rotate. At this time, the toggle ring 27 continues to move forward and disengages from the steering rod. 31, when the threaded rod 36 drives the first slider 34 to move, it also drives the first driving pulley 39 and the second driving pulley 43 to rotate, and then drives the first belt 16 and the second driven pulley 41 to rotate through the conduction of the first belt 16 and the second belt 42, and then drives the intake fan blades 40 and the exhaust fan blades 9 to start rotating. When the intake fan blades 40 rotate, the external air is sucked into the air inlet chamber shell 14. The external air enters the air inlet chamber shell 14, first passes through the first filter screen 12 to filter out impurities and dust, and then is heated by the heating net 37 and blown to the inside of the paint spraying room shell 11 to dry the paint on the surface of the plastic parts. At the same time, the rotation of the exhaust fan blades 9 will extract the air in the exhaust chamber shell 20 to the external environment, and then The moisture-mixed air and paint-liquid-mixed air generated during the drying process and the painting process are sucked into the exhaust chamber shell 20, and the paint-liquid-mixed air is filtered out by the second filter screen 21, and the moisture-mixed air is extracted to the outside of the paint spray room shell 11 to ensure a dry drying environment for the paint spray room shell 11. When the first slider 34 moves to the front end of the threaded rod 36, the second protective net 46 is opened through the second bearing 47, and then the dried plastic parts are taken out. After the second protective net 46 is closed, the drive motor 18 is started again to reverse, driving the first slider 34 to move to the initial position. During this process, the toggle ring 27 will contact and squeeze the steering rod 31 again, driving the connecting rod 24 to rotate, and then driving the nozzle 23 to return to its initial position.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
