Description

Technical Field

[0001] The invention belongs to the technical field of spraying equipment, and in particular relates to an anti-corrosion spraying device for the surface of a hardware die-casting product. Background Art

[0002] Hardware products are often used in daily life. In order to extend the service life of hardware products, preservatives are sprayed on the surface of some hardware products to increase the corrosion resistance of the hardware products. However, there are the following problems in actual spraying:

[0003] Sagging occurs:

[0004] 1. The spraying material is not stirred evenly or the stirring time is too long. When it is not stirred evenly, the viscosity of the local coating is low, and the coating is too thick during spraying, which affects the spraying quality. If the stirring time is too long, air will enter the coating and cannot be released well, which will cause the pinhole problem;

[0005] 2. Many workpieces are not always flat, and the existing spray gun is fixed at a fixed distance from the workpiece. When spraying at different positions on the workpiece surface, the distance between the spray gun and the workpiece surface keeps changing, which leads to uneven spraying of the preservative on the workpiece surface, affecting the overall spraying quality.

[0035] The operating principle of the present invention is described as follows: through the workbench 1, fixed tube 2, hollow placement plate 3, negative pressure suction hole 4, vacuum pump 5, suction tube 6, workpiece surface detection power supply adjustment mechanism 7 and self-adjusting spraying mechanism 8, the workpiece to be sprayed is placed on the hollow placement plate 3, and the vacuum pump 5 is started. The vacuum pump 5 cooperates with the suction tube 6 and the fixed tube 2 to form negative pressure suction into the hollow placement plate 3, and then acts on the bottom of the workpiece through the negative pressure suction hole 4, so that the workpiece is stably placed on the hollow placement plate 3, and spraying When the hollow placing plate 3 drives the workpiece to rotate, as the workpiece rotates, the detection rod 72 first contacts the outside of the workpiece, and the detection rod 72 moves back and forth with the change of the concave and convex surface of the workpiece in cooperation with the reset spring 74, thereby driving the anti-slip plate 73 to drive the sliding block 79 to move on the guide sliding rod 78, and the sliding block 79 drives the electric needle 710 to move on the resistance strip 76, thereby adjusting the power supply of the regulating electromagnetic block 87 in the self-regulating spraying mechanism 8, and the changed power supply is reflected by the delay controller after a certain delay. Feed to the adjusting electromagnetic block 87 to act, cooperate with the workpiece corresponding position after the detection position to move to the position of the spray head 82 for operation, when the workpiece surface is convex, the detection rod 72 moves backward, so that the resistance of the circuit connected to the resistor bar 76 is reduced, thereby increasing the power supply of the adjusting electromagnetic block 87, and the adjusting electromagnetic block 87 produces a larger magnetic attraction, cooperate with the adjusting permanent magnet block 86 to drive the spray head 82 to move back, when the workpiece surface is relatively concave, the detection rod 72 moves forward relatively, so that the resistance of the circuit connected to the resistor bar 76 is increased, the power supply obtained by the adjusting electromagnetic block 87 becomes smaller, the magnetic attraction is reduced, and the squeezing spring 85 pushes the spray head 82 forward, so that the spray head 82 maintains a stable distance from the workpiece surface, and the spray pump 11 cooperates with the elastic spray pipe 10 to draw the preservative from the storage box 9 and spray it on the surface of the workpiece, and can automatically adjust the spraying position of the workpiece surface according to the specific concave and convex pattern of the workpiece surface, so that the distance between the spray head 82 and the workpiece remains fixed, thereby ensuring the uniform spraying of the preservative on the entire workpiece surface, and improving the spraying quality;

[0036] Through the storage box 9, elastic spray pipe 10, spray pump 11, stirring mechanism 12, double-axis motor 13, first magnetic fixing mechanism 14 and intermittent power supply mechanism 15, the double-axis motor 13 drives the stirring rod 121 to rotate, and then drives the multiple stirring blades 122 to rotate, so as to realize the rapid mixing and stirring of the materials in the storage box 9. The first pulley assembly 18 realizes the synchronous rotation of the two stirring rods 121, improves the mixing and uniform stirring operation of the preservative in the storage box 9, and the output end of the double-axis motor 13 is connected to one end of the stirring rod 121 through the first magnetic fixing mechanism 14. With the power input of the double-axis motor 13, the output end of the other end of the double-axis motor 13 drives the small diameter gear 156 to rotate, and the reduction transmission of the pin shaft 154 is realized through the meshing action of the small diameter gear 156 and the large diameter gear 155, driving the conductive block on the outside of the large diameter gear 155 When the conductive block 157 moves and contacts the outside of the arc-shaped electrical connection block 152, power is supplied to the first magnetic attraction electromagnetic block 144, so that the first magnetic attraction electromagnetic block 144 generates magnetism and is magnetically connected to the first magnetic attraction permanent magnet block, so as to realize the power transmission between the output end of the dual-axis motor 13 and the stirring rod 121. When the conductive block 157 moves to a position where it does not contact the arc-shaped electrical connection block 152, power supply to the first magnetic attraction electromagnetic block 144 is cut off, so that the output end of the dual-axis motor 13 is not connected to the stirring rod 121, and the stirring of the preservative in the storage box 9 is stopped. The coating in the storage box 9 can be automatically stirred, and intermittent stirring and non-stirring work can be switched back and forth, which not only ensures the uniform stirring performance of the coating, but also avoids the problem that the stirring time is too long, which will cause air to enter the coating and cannot be released well, thereby causing the pinhole phenomenon. No manual direct control is required, and the operation is convenient.

[0037] Through the provided linkage rod 16, transmission shaft 17, first pulley assembly 18, second magnetic fixing mechanism 19 and reduction transmission mechanism 20, when the power of the dual-axis motor 13 is input, the transmission shaft 17 is driven to rotate synchronously through the second pulley assembly 123, and the transmission shaft 17 cooperates with the second magnetic fixing mechanism 19 to drive the linkage rod 16 to rotate synchronously, and one end of the linkage rod 16 drives the active bevel gear 205 to rotate, and the active bevel gear 205 and the driven bevel gear 204 are meshed to drive the rotating shaft 201 to rotate, and the upper end of the rotating shaft 201 drives the driving gear 202 to rotate, and the driving gear 20 2 and the meshing action of the synchronous gear 203 drives the fixed tube 2 to rotate, thereby realizing the stable and uniform rotation of the hollow placement plate 3, and when it is necessary to pick up and place the workpiece, the power supply to the second magnetic attraction electromagnetic block 194 is cut off, so that the transmission shaft 17 and the linkage rod 16 are disconnected, so that the hollow placement plate 3 stops rotating, and the power of the dual-axis motor 13 can be directly used to drive the hollow placement plate 3 to rotate by itself, thereby ensuring the spraying efficiency, and the power input can be automatically disconnected when rotating or stopping as needed, which is convenient for actual operation and use, and no additional power source is required. One motor can control the drive of multiple mechanisms, which is easy to control and saves costs.
