Description

Technical Field

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

[0002] Metal surface painting is a method to protect metals from oxidation and corrosion. Corrosion phenomena that occur around us refer to the damage, performance degradation, or deterioration of various materials under environmental influences. Metal surface painting is a very important means of metal corrosion protection. A good paint coating is continuous, intact, and well-bonded, and can act as a barrier to inhibit the intrusion of corrosive media. In the process of metal pipe processing, it is necessary to paint the surface of the pipe using a painting device.

[0003] The patent CN219024725U discloses a painting equipment for metal pipe surface processing, comprising a processing box. A storage bin and a feed pump are fixedly installed on the upper end of the processing box. The feed pump's inlet is connected to the inside of the storage bin via a pipe, and the feed pump's outlet extends into the processing box and is connected to a spray nozzle. This utility model utilizes the cooperation of a support plate, support block, second rotating rod, positioning block, first bevel gear, first rotating rod, second bevel gear, spur gear, and rack to allow the metal pipe to be flipped during movement, facilitating comprehensive painting. The first bevel gear, in conjunction with the second bevel gear, drives the metal pipe to rotate, resulting in more even painting. Subsequently, the spur gear, in conjunction with the rack, drives the first rotating rod, which in turn drives the second bevel gear.

[0004] However, this existing technology can only paint a single metal pipe, which is not convenient for holding multiple valves for painting. Painting only a single valve is inefficient and reduces work efficiency.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a painting device for metal product processing that can effectively solve the above-mentioned technical problems.

[0012] Furthermore, the surface of the clamp is fixedly connected with an anti-slip sleeve, and the anti-slip sleeve is conical.

[0013] Furthermore, a first guide rod is slidably mounted on the lower end of the movable plate, and both ends of the first guide rod are fixedly mounted on the housing.

[0014] Furthermore, the transmission assembly includes: a large gear fixedly mounted on the reciprocating lead screw; and a small gear fixedly mounted on the clamp, with adjacent small gears meshing with each other, and the surface of the large gear meshing with the surface of the adjacent small gear.

[0015] Furthermore, the baffle assembly includes: a baffle; a second guide rod for guiding the movement of the baffle, with both ends of the second guide rod fixedly mounted on the housing; a spring fitted on the second guide rod, with one end of the spring fixedly mounted on the baffle and the other end of the spring fixedly mounted on the housing; and a push plate fixedly mounted on the movable plate, with one end of the push plate resting on the surface of one side of the baffle.

[0025] like Figures 1 to 4 As shown, the present invention provides a painting device for metal product processing, comprising: a housing 1; a clamping assembly 2 disposed on the housing 1 for clamping a pair of metal tubes; a painting assembly 3 disposed on the housing 1 for spraying paint onto multiple metal tubes; and a blocking assembly 5 for blocking the sprayed paint.

[0026] The clamping assembly 2 includes: a fixed plate 201 fixedly mounted on the housing 1; a movable plate 202 slidably mounted on the housing 1, with the movable plate 202 and the fixed plate 201 being opposite to each other; an electric cylinder 203 that drives the movable plate 202 to move, with the electric cylinder 203 fixedly mounted on the housing 1; and a plurality of clamps 204 that are equidistantly rotatably mounted on the fixed plate 201 and the movable plate 202.

[0027] The painting assembly 3 includes: a motor 301 fixedly mounted on the housing 1, preferably a low-speed motor; a reciprocating lead screw 302 fixedly mounted on the output end of the motor 301, with both ends of the reciprocating lead screw 302 rotatably mounted on the housing 1 via bearings; a movable plate 303 threaded onto the surface of the reciprocating lead screw 302; a paint spraying pipe 304 fixedly mounted on the movable plate 303; a plurality of atomizing nozzles 305 communicating with the paint spraying pipe 304; and a transmission assembly 4 disposed on the reciprocating lead screw 302 to drive the plurality of metal pipes to rotate.

[0028] It should be added that a through groove is provided on the top of the box 1, and one end of the paint spraying pipe 304 extends to the outside of the box 1 through the same side. The paint spraying pipe 304 is connected to a liquid storage device at one end to deliver paint to the paint spraying pipe 304.

[0029] In the process of painting metal pipes, one end of multiple metal pipes is fitted onto the clamp 204. The output end of the electric cylinder 203 pushes the movable plate 202 to move closer to the fixed plate 201. After the movable plate 202 moves into place, the other end of the metal pipe is fitted onto the clamp 204 on the surface of the fixed plate 201, thus completing the clamping and positioning of multiple metal pipes. Then, the output end of the motor 301 rotates the reciprocating screw 302, causing the movable plate 303 threaded on the surface of the reciprocating screw 302 to move. This allows the atomizing nozzle 305 on the paint spraying pipe 304 fixed on the surface of the movable plate 303 to perform painting operations on the corresponding metal pipe surfaces.

[0030] It should be added that guide columns are symmetrically fixedly installed on the surface of the movable plate 202, and the guide columns penetrate one side of the box 1; the guide columns improve the stability of the movement of the movable plate 202.

[0031] It should be added that the surface of the clamp 204 is fixedly connected with an anti-slip sleeve 2041, and the anti-slip sleeve 2041 is conical; the anti-slip sleeve 2041 is preferably anti-slip rubber. When the fixed plate 201 and the movable plate 202 move relative to each other, the two ends of the metal tube are tightened and fixed by the conical anti-slip sleeve 2041, which further improves the stability of the metal tube clamping.

[0032] It should be added that a first guide rod 306 is slidably installed at the lower end of the movable plate 303, and both ends of the first guide rod 306 are fixedly installed on the housing 1; it guides the movement of the movable plate 303 and improves the stability of the movement of the movable plate 303.

[0033] To improve the uniformity of paint spraying on the surface of the metal pipe, the transmission assembly 4 includes: a large gear 401 fixedly mounted on the reciprocating lead screw 302; a small gear 402 fixedly mounted on the clamp 204, with adjacent small gears 402 meshing with each other, and the surface of the large gear 401 meshing with the surface of the adjacent small gear 402.

[0034] During the rotation of the reciprocating screw 302, the large gear 401 fixed on the surface of the reciprocating screw 302 meshes with the small gear 402 at one end of the adjacent clamp 204, causing the clamp 204 to drive the clamped metal tube to rotate. Since the two adjacent clamps 204 are meshed through the small gear 402, multiple clamped metal tubes rotate simultaneously. When the moving plate 303 threaded on the surface of the reciprocating screw 302 drives the atomizing nozzle 305 on the paint spraying tube 304 to spray paint, multiple metal tubes can be sprayed synchronously at the same time, improving the painting efficiency. In addition, since the diameter of the large gear 401 is larger than the diameter of the small gear 402, it is equivalent to a reduction gear set. When the moving plate 303 on the reciprocating screw 302 moves at low speed driven by the motor 301, the small gear 402 can drive the metal tube clamped on the clamp 204 to rotate quickly, which facilitates uniform painting of the metal tube surface.

[0035] To reduce paint spraying on the front door of the cabinet 1 and facilitate observation of the painting process on the metal pipes inside the cabinet 1 by staff, the baffle assembly 5 includes: a baffle 501; a second guide rod 502 that guides the movement of the baffle 501, with both ends of the second guide rod 502 fixedly installed on the cabinet 1; a spring 503 fitted onto the second guide rod 502, with one end of the spring 503 fixedly installed on the baffle 501 and the other end of the spring 503 fixedly installed on the cabinet 1; and a push plate 504 fixedly installed on the movable plate 303, with one end of the push plate 504 resting on the surface of one side of the baffle 501.

[0036] A baffle 501 is positioned on the opposite side of the atomizing nozzle 305. When the atomizing nozzle 305 moves to spray paint, the push plate 504 at the bottom of the moving plate 303 pushes the baffle 501 to move, so that the baffle 501 moves with the atomizing nozzle 305, thereby blocking the sprayed excess paint and reducing the amount of paint sprayed on the cabinet door on the front side of the cabinet 1, preventing it from affecting the staff's observation of the painting situation of the metal pipes inside the cabinet 1.

[0037] Working principle: When the power is turned on, during the painting process of metal tubes, one end of multiple metal tubes is fitted onto the clamp 204. The output end of the electric cylinder 203 pushes the movable plate 202 to move closer to the fixed plate 201. After the movable plate 202 moves into position, the other end of the metal tube is fitted onto the clamp 204 on the surface of the fixed plate 201, completing the clamping and positioning of multiple metal tubes. Then, the output end of the motor 301 rotates the reciprocating screw 302, causing the movable plate 303 threaded on the surface of the reciprocating screw 302 to move. This causes the atomizing nozzle 305 on the paint spray tube 304 fixed on the surface of the movable plate 303 to spray onto the corresponding metal tube. The surface is sprayed with paint. During the rotation of the reciprocating screw 302, the large gear 401 fixed on the surface of the reciprocating screw 302 meshes with the small gear 402 at one end of the adjacent clamp 204, causing the clamp 204 to drive the clamped metal tube to rotate. Since the two adjacent clamps 204 are meshed through the small gear 402, the clamped metal tubes rotate simultaneously, resulting in uniform spraying of paint on the surface of the metal tubes. Furthermore, the push plate 504 at the bottom of the moving plate 303 pushes the baffle 501 to move, causing the baffle 501 to move along with the atomizing nozzle 305, thereby blocking the sprayed excess paint and reducing the amount of paint sprayed on the cabinet door on the front side of the box 1.
