The spraying system of the device sprays the pigment evenly onto the surface of the copper mold through a spray gun or nozzle. At present, after the copper mold parts are processed, they usually need to be sprayed with protective paint or protective materials on their surface to achieve rust-proof, corrosion-proof and beautiful effects.

The patent arranges a light transmitter and a light receiver on the nozzle, and the light transmitter falls on the casting and is reflected by the light receiver, and the light reflected by the light receiver is fed back to the control panel, and then the control panel controls the third motor to drive the nozzle to rotate, so that the nozzle is always perpendicular to the position of the arc surface tangent, and the connecting block stretches or compresses the spring through the sliding rod sliding in the arc groove to drive the liquid storage cylinder and the nozzle to move up and down, so as to achieve the same distance between the nozzle and the arc surface of the casting, so that the spraying is uniform and the spraying quality is improved.

Through the setting of the above structure, the U-shaped bracket 7 drives the nozzle component 6 to adapt to the spacing between the arc surfaces of copper mold castings of different specifications, thereby ensuring that the distance between the nozzle component 6 and the arc surface of the arc copper mold casting remains consistent, avoiding the inconsistent distance between the nozzle component 6 and the arc surface of the casting, and the problem of uneven spraying of paint on the surface of the casting.

[0026] The U-shaped bracket 7 is provided with a sliding carriage 10 at the bottom outer wall of both sides, and a spring is provided between the carriage 10 and the outer wall of the U-shaped bracket 7. The two carriages 10 are rotatably provided with rubber dust-sticking rollers 11. The left and right sides of the rubber dust-sticking rollers 11 are fixed with a resistance wheel 12, and the resistance wheel 12 is in contact with the top of the base 1. A curved box 13 is fixedly installed between the rear sides of the two carriages 10 through a bracket, and the curved box 13 is in contact with the outer wall of the rubber dust-sticking roller 11. Through the arrangement of the above structure, the rubber dust-sticking roller 11 can adhere to the impurities on the surface of the copper mold casting, making the surface of the copper mold casting smoother and cleaner, so that the paint can be better adhered to the surface of the copper mold casting during spraying, avoiding problems such as uneven coating or falling off caused by the presence of impurities, and improving the quality and durability of the coating. At the same time, the curved box 13 scrapes the impurities adhered to the surface of the rubber dust-sticking roller 11 into the curved box 13, so as to facilitate the rubber dust-sticking roller 11 to continuously adhere to and clean the impurities on the surface of the copper mold casting.

[0027] A shielding device 8 is provided above the rubber dust sticking roller 11 to prevent dripping from the nozzle of the nozzle assembly 6. The shielding device 8 includes two fixed blocks 81, two elastic telescopic columns 82, four positioning rods 83, two L-shaped slides 84, two friction plates 85, two L-shaped plates 88, and a shielding plate 89. The two fixed blocks 81 are respectively fixed to the left and right sides of the U-shaped frame 3, the two L-shaped slides 84 are respectively slidably installed at the bottom of the two fixed blocks 81, the shielding plate 89 is fixed between the two L-shaped slides 84, and the shielding plate 89 is located directly below the nozzle assembly 6, one end of the two elastic telescopic columns 82 is respectively fixed to the rear side of the two fixed blocks 81, the other end of the two elastic telescopic columns 82 is respectively fixed to the top of the two L-shaped slides 84, the four positioning rods 83 They penetrate through and are slidably installed on the tops of the two L-shaped slides 84 respectively, and a spring is provided between the positioning rod 83 and the L-shaped slide 84. The two friction plates 85 are respectively fixed on the bottoms of the two adjacent positioning rods 83. The two L-shaped plates 88 are both fixed on the top front side of the base 1. The top rear side of the L-shaped plate 88 is provided with a chamfer, and the front side of the friction plate 85 is provided with a chamfer. The top surface of the L-shaped plate 88 contacts the bottom surface of the friction plate 85, and the friction plate 85 is located directly above the resistance wheel 12. Through the arrangement of the above-mentioned structure, the L-shaped slide 84 drives the shielding plate 89 to reset and form a shielding under the nozzle assembly 6. The shielding plate 89 can prevent paint from splashing onto the surrounding area or equipment under the nozzle, avoiding pollution or unnecessary cleaning work, while ensuring the cleanliness and safety of the working environment.

[0028] The shielding device 8 also includes two spring plates 86 and two ratchet gears 87. The two ratchet gears 87 are respectively fixed on the side of the two contact wheels 12 that are away from each other. The two spring plates 86 are respectively fixed on the left and right sides of the U-shaped bracket 7 through brackets. The end of the spring plate 86 away from the U-shaped bracket 7 is located on the sawtooth motion trajectory of the ratchet gear 87. Through the setting of the above structure, the ratchet gear 87 limits the rotation trajectory of the rubber dust sticking roller 11 through the contact wheel 12, so that the rubber dust sticking roller 11 will not rotate in the opposite direction, thereby avoiding the reverse rotation of the rubber dust sticking roller 11, which causes the impurities adhered to the surface of the rubber dust sticking roller 11 to cause secondary pollution to the surface of the copper mold casting.

[0029] When in use, the copper mold casting is placed in the concave mold groove of the base 1, and the screw 2 is driven by the motor to rotate. The screw 2 drives the U-shaped frame 3 to move along the outside of the base 1 toward the rear side of the base 1. The base 1 drives the nozzle assembly 6 to move along through the lateral movement assembly 4. In this process, the nozzle assembly 6 is started, and the nozzle assembly 6 can spray protective paint or protective materials on the surface of the copper mold casting. When the U-shaped frame 3 moves, the U-shaped frame 3 drives the U-shaped bracket 7 to move along. When the semicircular shape of the U-shaped bracket 7 contacts the curved surface of the copper mold casting, the curved surface of the copper mold casting pushes the U-shaped bracket 7 to move upward, and the U-shaped bracket 7 drives the nozzle assembly 6 to move upward. The spring corresponding to the nozzle assembly 6 is compressed, so that the U-shaped bracket 7 drives the nozzle assembly 6 to adapt to the spacing between the curved surfaces of copper mold castings of different specifications, thereby ensuring that the distance between the nozzle assembly 6 and the curved surface of the curved copper mold casting is consistent, avoiding the inconsistent distance between the nozzle assembly 6 and the curved surface of the casting, and the problem of uneven spraying of paint on the casting surface; at the same time When the U-shaped bracket 7 moves, the U-shaped bracket 7 drives the slide 10 to move along with it, and the slide 10 drives the rubber dust sticking roller 11 and the abutting wheel 12 to move synchronously. When the rubber dust sticking roller 11 contacts the arc surface of the copper mold casting, the rubber dust sticking roller 11 drives the slide 10 to move upward along the outer wall of the U-shaped bracket 7, and the spring corresponding to the slide 10 is compressed. Under the action of the spring force corresponding to the slide 10, the slide 10 drives the rubber dust sticking roller 11 to be close to the surface of the copper mold casting. When moving, the rubber sticky roller 11 will adhere to the impurities on the surface of the copper mold casting, making the surface of the copper mold casting smoother and cleaner, so that the paint can better adhere to the surface of the copper mold casting during spraying, avoiding problems such as uneven coating or shedding due to the presence of impurities, thereby improving the quality and durability of the coating. At the same time, the arc box 13 scrapes the impurities adhered to the surface of the rubber sticky roller 11 into the arc box 13, thereby facilitating the rubber sticky roller 11 to continuously adhere to and clean the impurities on the surface of the copper mold casting.

[0030] When the U-shaped frame 3 does not move, the top surface of the L-shaped plate 88 contacts the bottom surface of the friction plate 85, and the friction plate 85 does not contact the outer wall of the abutting wheel 12. When the U-shaped frame 3 drives the U-shaped bracket 7 to move, the U-shaped bracket 7 drives the elastic telescopic column 82 to move through the fixed block 81, and the elastic telescopic column 82 drives the L-shaped slide plate 84 to move. The L-shaped slide plate 84 drives the friction plate 85 away from the L-shaped plate 88 through the positioning rod 83. At this time, the top surface of the L-shaped plate 88 is no longer in contact with the bottom surface of the friction plate 85. Under the action of the spring force corresponding to the positioning rod 83, the positioning rod 83 pushes the friction plate 85 to contact the outer wall of the abutting wheel 12. When the rubber dust sticking roller 11 contacts and moves with the surface of the copper mold casting, The copper mold casting drives the rubber dust sticking roller 11 to rotate, and the rubber dust sticking roller 11 drives the contact wheel 12 to rotate. Under the friction between the contact wheel 12 and the friction plate 85, the contact wheel 12 drives the friction plate 85 to move toward the rear side. The friction plate 85 drives the L-shaped slide plate 84 to slide along the bottom of the fixed block 81 through the positioning rod 83. The L-shaped slide plate 84 drives the elastic telescopic column 82 to stretch. The L-shaped slide plate 84 drives the shielding plate 89 to move toward the rear side. The shielding plate 89 moves out from under the nozzle assembly 6. The shielding plate 89 no longer forms a shield under the nozzle assembly 6. At this time, the nozzle assembly 6 can spray protective paint or protective materials on the surface of the copper mold casting. When a copper mold casting After the surface spraying operation is completed, when the nozzle assembly 6 is not in use, the U-shaped frame 3 drives the U-shaped bracket 7 to move to the front side of the base 1. At this time, the chamfer of the L-shaped plate 88 pushes the chamfered inclined surface of the friction plate 85 to drive the friction plate 85 to move upward. At this time, the friction plate 85 does not contact the outer wall of the resistance wheel 12. Under the elastic force of the elastic telescopic column 82, the L-shaped slide plate 84 drives the friction plate 85 to reset through the positioning rod 83. The L-shaped slide plate 84 drives the shielding plate 89 to reset and form a shield under the nozzle assembly 6. The shielding plate 89 can prevent the paint from splashing onto the surrounding area or equipment under the nozzle, avoiding pollution or unnecessary cleaning work, while ensuring the cleanliness and safety of the working environment. At the same time, When the U-shaped frame 3 drives the U-shaped bracket 7 to move to the front side of the base 1, the rubber dust-sticking roller 11 tends to rotate in the opposite direction. The rubber dust-sticking roller 11 drives the ratchet gear 87 to rotate in the opposite direction through the contact wheel 12. At this time, the serrated right-angled part of the ratchet gear 87 touches the spring plate 86. The spring plate 86 presses against the serrated right-angled part of the ratchet gear 87 to limit the rotation trajectory of the ratchet gear 87. The ratchet gear 87 limits the rotation trajectory of the rubber dust-sticking roller 11 through the contact wheel 12, so that the rubber dust-sticking roller 11 will not rotate in the opposite direction, thereby avoiding the reverse rotation of the rubber dust-sticking roller 11, resulting in the problem that impurities adhered to the surface of the rubber dust-sticking roller 11 will cause secondary pollution to the surface of the copper mold casting.

[0031] See also Figure 1-7 On the basis of the above embodiment, in another embodiment of the present invention, an anti-adhesion device 9 is provided at the arc box 13 for preventing impurities from adhering between the arc box 13 and the rubber dust-sticking roller 11.

[0032] The anti-adhesion device 9 includes two elastic telescopic rods 91, a long rod 92, a connecting rod 93, and a plurality of L-shaped knocking rods 94. The long rod 92 is fixed to the rear side of the curved box 13, and the two elastic telescopic rods 91 are respectively fixed to the front left side and the front rear side of the long rod 92. The connecting rod 93 is fixed between the tops of the telescopic ends of the two elastic telescopic rods 91. A plurality of L-shaped knocking rods 94 are evenly and equidistantly fixed to the bottom of the connecting rod 93. The front side of the elastic telescopic rod 91 is circularly arranged. 1 is located on the sawtooth motion trajectory of the ratchet gear 87, and one end of the L-shaped knocking rod 94 away from the connecting rod 93 contacts the inner wall of the cambered box 13. Through the arrangement of the above structure, the connecting rod 93 drives the L-shaped knocking rod 94 to impact the inner wall of the cambered box 13, and the inner wall of the cambered box 13 vibrates and drives the scraped impurities to vibrate, thereby avoiding the impurities adhering between the cambered box 13 and the rubber dust-sticking roller 11, resulting in the problem that the impurities will cause secondary pollution to the rubber dust-sticking roller 11.

[0033] The anti-adhesion device 9 also includes a plurality of U-shaped rods 95 and a plurality of thorn rods 96. The plurality of U-shaped rods 95 are evenly and equidistantly fixed on the top of the connecting rod 93, and the plurality of thorn rods 96 are respectively fixed on the rear side of one end of the plurality of U-shaped rods 95 away from the connecting rod 93, and the thorn rods 96 are located on the front side of the rubber dust-sticking roller 11. Through the arrangement of the above-mentioned structure, the thorn rods 96 pierce holes in the rubber dust-sticking roller 11. The holes on the surface of the rubber dust-sticking roller 11 can increase the contact area between the impurities and the rubber dust-sticking roller 11, thereby increasing the adhesion force, which helps to more effectively adsorb and fix impurities and improves the efficiency of removing impurities from the copper mold surface.

[0034] When in use, while the U-shaped frame 3 drives the U-shaped bracket 7 to move to the rear side of the base 1, the rubber dust-sticking roller 11 drives the ratchet gear 87 to rotate forwardly through the abutment wheel 12, and the serrations of the ratchet gear 87 push the circular shape of the elastic telescopic rod 91 to drive the telescopic end of the elastic telescopic rod 91 to move toward the rear side, and the telescopic end of the elastic telescopic rod 91 drives the connecting rod 93 to move toward the rear side, and the connecting rod 93 drives the L-shaped knocking rod 94 away from the inner wall of the arc box 13. When the serrations of the ratchet gear 87 no longer push the circular shape of the elastic telescopic rod 91, under the elastic force of the elastic telescopic rod 91, the telescopic end of the elastic telescopic rod 91 is reset and drives the connecting rod 93 to reset, and the connecting rod 93 drives the L-shaped knocking rod 94 to the arc box 13 The inner wall of the cambered box 13 is impacted, and the inner wall of the cambered box 13 vibrates and drives the scraped impurities to vibrate, thereby avoiding the impurities adhering between the cambered box 13 and the rubber dust-sticking roller 11, causing the impurities to cause secondary pollution to the rubber dust-sticking roller 11; at the same time, when the connecting rod 93 moves to the rear side, the connecting rod 93 drives the U-shaped rod 95 to lean against the rubber dust-sticking roller 11, and the connecting rod 93 drives the thorn rod 96 to lean against the rubber dust-sticking roller 11, so that the thorn rod 96 pierces the rubber dust-sticking roller 11, and the holes on the surface of the rubber dust-sticking roller 11 can increase the contact area between the impurities and the rubber dust-sticking roller 11, thereby increasing the adhesion, which helps to more effectively adsorb and fix the impurities, and improves the efficiency of removing impurities from the surface of the copper mold.
