Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a metal product surface spraying equipment. Background Technology

[0002] Metal products are increasingly used in various fields of industry, agriculture and people's lives, and they are creating more and more value for society. In order to improve the appearance and rust prevention of metal products, the surface of metal products is painted. Therefore, a metal product surface painting equipment is needed to complete the painting of the surface of metal products.

[0003] According to a public notice (Announcement No.: CN222889976U) of a metal product surface spraying equipment, the above application includes a track frame, a placement frame fixedly connected to the track frame, a drive seat slidably connected to the track frame, an electric push rod fixedly connected to the drive seat, an adjustment frame fixedly connected to the output end of the electric push rod, a spraying plate slidably connected to the adjustment frame, and multiple nozzles arranged and fixedly on the bottom surface of the spraying plate, and a heating lamp fixedly on the bottom surface of the spraying plate.

[0004] However, in actual use, the nozzles of the above-mentioned spraying equipment are only set on the bottom surface of the spraying plate, and the spraying direction is only downward. This directly results in only covering the top plane, while the side and edge areas become blind spots for spraying. It is necessary to manually turn the metal products over and repeat the spraying multiple times. In view of this, we propose a metal product surface spraying equipment. Utility Model Content

[0005] The purpose of this invention is to provide a metal product surface spraying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal product surface spraying device, including a workbench, a rotating assembly on the top of the workbench, a spraying assembly directly above the workbench, the rotating assembly including a rotating rod rotatably connected to the top end face of the workbench, a support tray fixedly connected to the top end face of the rotating rod, a drive motor fixedly connected to the bottom end face of the workbench, a rotating shaft fixedly connected to the output end of the drive motor, a belt one and a belt two provided on the side wall of the rotating shaft, a rotating rod rotatably connected to the side wall of the workbench, and a half gear fixedly connected to the top end of the rotating rod.

[0007] Preferably, a pulley is fixedly connected to the side wall of the rotating shaft and the side wall of the rotating rod, and the pulley is driven by a belt. A second pulley is fixedly connected to the side wall of the rotating shaft and the side wall of the rotating rod, and the second pulley is driven by a belt. Through the first belt and the second belt, the rotation of the rotating shaft drives the rotating rod and the rotating rod to rotate.

[0008] Preferably, the inner bottom surface of the support tray has through holes, and the number of through holes is set in several groups. The several groups of through holes are evenly spaced on the inner bottom surface of the support tray, and the paint is discharged through the through holes to avoid the workpiece being immersed in the paint.

[0009] Preferably, the spraying assembly includes a fixed frame fixedly connected to the side wall of the workbench, the fixed frame being slidably connected to a sliding frame, a limit crossbar being fixedly connected to the side wall of the sliding frame, a guide frame being fixedly connected to the side wall of the fixed frame, a spray head being slidably connected to the top of the guide frame, a connecting rod being hinged to the top end face of the spray head, and the spray head sliding along the guide frame to change the spraying position of the spray head.

[0010] Preferably, the connecting rod is movably connected to the inner wall of the limiting crossbar, the guide frame is arc-shaped, and the connecting rod and the nozzle are moved laterally back and forth by the limiting crossbar. The arc-shaped guide frame allows the nozzle to spray onto the side wall of the workpiece when it moves to both sides of the guide frame.

[0011] Preferably, the inner wall of the sliding frame is fixedly connected with teeth, which mesh with the half gear. The rotation of the half gear drives the sliding frame and the limiting crossbar to perform lateral reciprocating motion.

[0012] Preferably, a cover is fixedly connected to the side wall of the workbench, and a heating plate is fixedly connected to the side wall of the cover.

[0013] Compared with the prior art, the present invention provides a metal product surface spraying device, which has the following beneficial effects:

[0014] 1. This metal product surface spraying equipment, through the setting of a rotating component and a spraying component, allows the spraying angle and position of the nozzle to change during the transverse reciprocating motion. This enables the nozzle to spray the sidewalls of the workpiece when it moves to the sides of the guide frame, avoiding spraying dead corners, improving the uniformity and integrity of the sidewall spraying, reducing the need for manual turning of the metal product, and improving spraying efficiency. The rotating workpiece and the transverse reciprocating spraying of the nozzle work together to allow the sidewalls of the workpiece to be sprayed from multiple angles and directions, thereby significantly improving the sufficiency and consistency of the sidewall spraying and enhancing the overall spraying quality.

[0015] 2. This metal product surface spraying equipment, through the setting of a heating plate, puts the workpiece in a state of being surrounded and heated by hot airflow, which improves the fluidity and evaporation conditions of the spray liquid when it comes into contact with the workpiece surface, thereby promoting better adhesion of the spray liquid to the workpiece surface and facilitating the uniform spread of the sprayed coating.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a metal product surface spraying device, including a workbench 1, a rotating component 2 is provided on the top of the workbench 1, and a spraying component 3 is provided directly above the workbench 1. The rotating component 2 includes a rotating rod 201 rotatably connected to the top end face of the workbench 1, a support tray 202 is fixedly connected to the top end face of the rotating rod 201, a drive motor 203 is fixedly connected to the bottom end face of the workbench 1, a rotating shaft 204 is fixedly connected to the output end of the drive motor 203, a belt 205 and a belt 207 are provided on the side wall of the rotating shaft 204, a rotating rod 206 is rotatably connected to the side wall of the workbench 1, and a half gear 208 is fixedly connected to the top end of the rotating rod 206.

[0022] In one embodiment of this utility model, a pulley is fixedly connected to the side wall of the rotating shaft 204 and the side wall of the rotating rod 201. The pulley is connected to the belt 205. A second pulley is fixedly connected to the side wall of the rotating shaft 204 and the side wall of the rotating rod 206. The second pulley is connected to the belt 207. Through the belt 205 and the belt 207, the rotation of the rotating shaft 204 drives the rotating rod 201 and the rotating rod 206 to rotate. The inner bottom surface of the support tray 202 is provided with through holes. Several sets of through holes are provided. The several sets of through holes are equally spaced on the inner bottom surface of the support tray 202. The paint is left through the through holes to avoid the workpiece being immersed in the paint.

[0023] The spraying assembly 3 includes a fixed frame 301 fixedly connected to the side wall of the workbench 1. The fixed frame 301 is slidably connected to a sliding frame 302. A limit crossbar 303 is fixedly connected to the side wall of the sliding frame 302. A guide frame 304 is fixedly connected to the side wall of the fixed frame 301. A spray head 305 is slidably connected to the top of the guide frame 304. A connecting rod 306 is hinged to the top end face of the spray head 305. The spray head 305 slides along the guide frame 304, changing the spraying position of the spray head 305. The connecting rod 306 and... The inner wall of the limiting crossbar 303 is movably connected, the guide frame 304 is arc-shaped, the connecting rod 306 and the nozzle 305 are driven by the limiting crossbar 303 to move laterally back and forth. The arc-shaped guide frame 304 allows the nozzle 305 to spray onto the side wall of the workpiece when it moves to both sides of the guide frame 304. The inner wall of the sliding frame 302 is fixedly connected with teeth, which mesh with the half gear 208. The rotation of the half gear 208 drives the sliding frame 302 and the limiting crossbar 303 to move laterally back and forth.

[0024] The metal product to be sprayed is placed on the support tray 202. The support tray 202 is rotatably connected to the top end face of the workbench 1 via the rotating rod 201. The metal product is supported and positioned by the support tray 202.

[0025] When the drive motor 203 is started, the output end of the drive motor 203 drives the rotating shaft 204 to rotate. The rotating shaft 204 has a pulley 1 and a pulley 2 fixedly connected to its side wall. The pulley 2 fixedly connected to the side wall of the rotating shaft 204 is connected to the pulley 2 fixedly connected to the side wall of the rotating rod 206 through the belt 207. This causes the rotating shaft 204 to rotate, which in turn drives the rotating rod 206 to rotate. The top of the rotating rod 206 is fixedly connected to a half gear 208. During the rotation, the half gear 208 meshes with the teeth fixedly connected to the inner wall of the sliding frame 302. The reciprocating meshing motion of the half gear 208 drives the sliding frame 302 to slide laterally back and forth on the fixed frame 301. The sliding frame 302 drives the limiting crossbar 303 fixedly connected to its side wall to move laterally back and forth synchronously.

[0026] The nozzle 305 is movably connected to the limiting crossbar 303 via the connecting rod 306. Driven by the limiting crossbar 303, the nozzle 305 slides along the guide frame 304. Since the guide frame 304 is arc-shaped, the spraying angle and position of the nozzle 305 change during the transverse reciprocating motion. This allows the nozzle 305 to spray the sidewalls of the workpiece when it moves to the sides of the guide frame 304, avoiding spraying dead corners, improving the uniformity and integrity of the sidewall spraying, reducing the need for manual turning of metal products, and improving spraying efficiency.

[0027] Meanwhile, the pulley is connected to the side wall of the rotating rod 201 via the belt 205, so that the rotation of the rotating shaft 204 synchronously drives the rotating rod 201 to rotate, thereby driving the support tray 202 to rotate, realizing the continuous rotation of the workpiece. The rotating workpiece cooperates with the transverse reciprocating spraying of the spray head 305, so that the side wall of the workpiece can be sprayed from multiple angles and directions, thereby significantly improving the fullness and consistency of the side wall spraying and improving the overall spraying quality.

[0028] In addition, a cover 4 is fixedly connected to the side wall of the workbench 1, and a heating plate 5 is fixedly connected to the side wall of the cover 4. The heating plate 5 heats the air inside the cover 4, thereby causing the hot air to rise through the through hole and heat the workpiece, improving the adhesion performance of the sprayed liquid.

[0029] When the heating plate 5 is powered on, it heats the air inside the cover 4, creating a hot air environment inside the cover 4. Due to the rising characteristic of hot air, the heated air flows from bottom to top inside the cover 4 and passes through several sets of through holes on the bottom surface of the support tray 202, thereby continuously heating the workpiece placed on the support tray 202. While the spray nozzle 305 is spraying the workpiece, the workpiece is surrounded and heated by the hot airflow, which improves the fluidity and evaporation conditions of the spray liquid when it comes into contact with the workpiece surface, thereby promoting better adhesion of the spray liquid to the workpiece surface and facilitating the uniform spread of the sprayed coating.

[0030] In this invention, the metal product to be sprayed is placed on the support tray 202. The support tray 202 is rotatably connected to the top of the workbench 1 via the rotating rod 201. After the drive motor 203 is started, its output end drives the rotating shaft 204 to rotate. The rotating shaft 204 drives the rotating rod 206 to rotate via the second belt 207, causing the sliding frame 302 and the limiting crossbar 303 to reciprocate laterally on the fixed frame 301. The limiting crossbar 303 drives the nozzle 305 to slide along the arc-shaped guide frame 304 via the connecting rod 306, realizing the change of the spraying position and angle of the nozzle 305. At the same time, the rotating shaft 204 drives the rotating rod 201 to rotate via the first belt 205, so that the support tray 202 drives the workpiece to rotate continuously. During the spraying process, the heating plate 5 heats the air inside the cover 4. The hot air heats the workpiece from bottom to top through the through hole of the support tray 202, realizing the coordinated work of rotation, reciprocating spraying and heating.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
