Description

Technical Field

[0001] This invention relates to the field of intelligent processing equipment technology, and in particular to a pipe spraying device. Background Technology

[0002] Traditional workpiece spraying equipment requires a displacement transmission device to drive the spray head to move back and forth, laterally, up and down, and deflect the spray head in order to achieve uniform spraying on the surface of the workpiece with many uneven structures. Therefore, the displacement transmission device generally includes a combination of translation mechanism, lifting mechanism and rotation mechanism, which is very complex and expensive.

[0003] For the spraying of pipe fittings, although the surface of the pipe fittings has few uneven structures, there are still some uneven areas. Therefore, the spraying head needs to be adjusted during the spraying process to ensure that the surface of the pipe fittings is sprayed evenly. However, if traditional workpiece spraying equipment is used, the equipment cost is high, and it would be wasteful to use it only for spraying pipe fittings. Moreover, there is no good structure among the existing spraying equipment that can be used for spraying pipe fittings. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a pipe coating device, which has low manufacturing cost, can effectively coat the surface of pipes, and has a good coating effect.

[0006] A pipe coating apparatus according to an embodiment of the present invention has at least the following beneficial effects:

[0007] The pipe coating device of the present invention, due to the shallow depth of the uneven structure on the surface of the pipe, the first transmission pipe extends along the rotation axis of the turntable, and after the first transmission pipe swings in the first clockwise direction and the second clockwise direction respectively, the first transmission pipe will form different tilt angles, so that the upper and lower end faces of the uneven structure can be coated. Although the first end or the tail end of the first transmission pipe is relatively far apart when some positions are coated, the paint sprayed by the coating component can still cover the surface of the pipe without causing too much impact. With relatively low manufacturing cost, the coating on the surface of the pipe is relatively uniform, which is suitable for coating pipes and has a good coating effect.

[0008] According to some embodiments of the present invention, the pipe spraying device further includes a transmission module, and there are multiple station modules, which are arranged at intervals on the transmission module.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] like Figure 1-4As shown, a pipe fitting 500 spraying device according to a first aspect embodiment of the present invention includes a station module 100 and a spraying module 200. The station module 100 includes a base 110 and a turntable 120, the turntable 120 being rotatably mounted on the base 110, and having an installation station for placing the pipe fitting 500. The spraying module 200 includes a base frame 210 and at least one first transmission pipe 220, the first transmission pipe 220 having a first transmission channel 221 for communicating with a paint source, and the first transmission pipe 220 having a plurality of transmission channels along its length. The spraying component 222 is connected to the channel. The first transmission pipe 220 is rotatably mounted on the base frame 210 and extends along the rotation axis of the turntable component 120, such that when the first transmission pipe 220 swings in a first clockwise direction, the first end of the first transmission pipe 220 is close to the pipe component 500 and the tail end of the first transmission pipe 220 is away from the pipe component 500. When the first transmission pipe 220 swings in a second clockwise direction, the first end of the first transmission pipe 220 is away from the pipe component 500 and the tail end of the first transmission pipe 220 is close to the pipe component 500. The first clockwise direction and the second clockwise direction are opposite to each other.

[0030] The workstation module 100 and the spraying module 200 can be set separately or fixed by a frame.

[0031] A rotary drive is provided on the base 110. The rotary drive is connected to the turntable 120 to drive the turntable 120 to rotate. The pipe 500 to be sprayed is placed vertically on the turntable 120. The spraying module 200 is located on one side of the station module 100. The spraying component 222 can spray the outer wall of the pipe 500. The turntable 120 rotates the pipe 500, so that the spraying component 222 can spray the outer peripheral wall of the pipe 500.

[0032] The paint source can transmit paint through the first transmission channel 221 to each spraying component 222, which can be a spray gun or nozzle, etc. Generally speaking, the middle part of the first transmission pipe 220 is rotatably connected to the base frame 210 or other objects, so that when the first transmission pipe 220 swings in a first clockwise direction, the first end of the first transmission pipe 220 is close to the pipe fitting 500, and the tail end of the first transmission pipe 220 is away from the pipe fitting 500; when the first transmission pipe 220 swings in a second clockwise direction, the first end of the first transmission pipe 220 is away from the pipe fitting 500, and the tail end of the first transmission pipe 220 is close to the pipe fitting 500.

[0033] The pipe 500 spraying device of the present invention, since the depth of the concave and convex structure on the surface of the pipe 500 is relatively shallow, the first transmission pipe 220 extends along the rotation axis of the turntable 120, and after the first transmission pipe 220 swings in the first clockwise direction and the second clockwise direction respectively, the first transmission pipe 220 will form different tilt angles, so that the upper and lower end surfaces of the concave and convex structure can be sprayed.

[0034] It should be noted that although the beginning or end of the first transmission pipe 220 is relatively far away from the pipe 500 during some spraying operations, since the spraying part 222 sprays out the paint, adjusting the swing angle of the first transmission pipe 220 is equivalent to adjusting the orientation angle of the spraying part 222. As a result, the paint can cover the surface of the pipe 500 during the spraying process without causing too much impact. With relatively low manufacturing costs, the coating on the surface of the pipe 500 is relatively uniform, which is suitable for spraying the pipe 500 and has a good spraying effect.

[0035] In some embodiments of the present invention, the pipe fitting 500 spraying device further includes a transmission module 400, and there are multiple station modules 100. The multiple station modules 100 are arranged at intervals on the transmission module 400, and the transmission module 400 can drive each station module 100 to pass through the spraying module 200 in sequence.

[0036] Workers can place each pipe 500 to be sprayed on the turntable 120. The transfer module 400 can sequentially transfer the station module 100 to the spraying module 200, and the spraying module 200 sprays each pipe 500 on the station module 100 one by one.

[0037] In some embodiments of the present invention, such as Figure 1 As shown, the transmission module 400 includes a ring-shaped transmission line assembly, and multiple station modules 100 are arranged at intervals on the transmission line assembly. The transmission line assembly can drive each station module 100 to pass through the spraying module 200 in a cyclic manner.

[0038] Each station module 100 can circulate through the spraying module 200 via the ring-shaped transmission line assembly. During the circulation of the station module 100, the operator can disassemble the already sprayed pipe fittings 500 and then place the pipe fittings 500 to be sprayed. The entire spraying process is carried out in an orderly manner, improving spraying efficiency.

[0039] The transmission line assembly includes a ring-shaped transmission track, roller units and rail grooves disposed at the bottom of each seat 110. The seat 110 is slidably disposed on the transmission track through the rail grooves. A rotary drive is disposed inside the seat 110. The rotary drive can drive the roller units to operate so as to move the workstation module 100 along the transmission track.

[0040] In some embodiments of the present invention, such as Figure 2 As shown, there are multiple first transmission tubes 220, and these multiple first transmission tubes 220 are spaced apart along the transmission direction of the transmission module 400.

[0041] The transmission module 400 can move the station module 100 to each of the first transmission pipes 220 in a corresponding manner, and each of the first transmission pipes 220 can spray each of the pipes 500 respectively, thereby improving the spraying efficiency.

[0042] In some embodiments of the present invention, such as Figure 2 As shown, the spraying module 200 also includes a second transmission pipe 240, which is mounted on the base frame 210. The second transmission pipe 240 has a second transmission channel 241 for communicating with the paint source. Multiple first transmission pipes 220 are arranged along the length of the second transmission pipe 240. The first transmission pipes 220 are rotatably mounted on the second transmission pipe 240, and the first transmission channel 221 communicates with the paint source through the second transmission channel 241.

[0043] The paint source transmits the paint into the second transmission channel 241, and then the paint is distributed from the second transmission channel 241 to each of the first transmission channels 221, and then sprayed out from the spraying parts 222 of each of the first transmission pipes 220. The structure is simple and the manufacturing cost is low.

[0044] In some embodiments of the present invention, such as Figure 3 As shown, the spraying module 200 also includes an arc-shaped second transmission pipe 240, which is mounted on the base frame 210. The second transmission pipe 240 has a second transmission channel 241 for communicating with the paint source. The second transmission pipe 240 is arranged around the rotation circumference of the turntable 120. There are multiple first transmission pipes 220, which are arranged along the length of the second transmission pipe 240. The first transmission pipes 220 are rotatably mounted on the second transmission pipe 240, and the first transmission channel 221 communicates with the paint source through the second transmission channel 241.

[0045] The transmission module 400 can also transmit a station module 100 to the vicinity of multiple first transmission pipes 220. The second transmission pipe 240 is arc-shaped and can partially surround the outer periphery of the turntable component 120 on the station module 100. The first transmission pipes 220 located at different positions can spray different positions around the same pipe component 500. With the rotation of the turntable component 120, the spraying efficiency can be higher, the spraying can be more uniform, and the spraying effect can be better.

[0046] In some embodiments of the present invention, such as Figure 4As shown, a collar mounting member 230 is provided on the first transmission pipe 220. The inner side wall of the collar mounting member 230 is provided with a first opening 231 that communicates with the first transmission channel 221. The second transmission pipe 240 is provided with a plurality of second openings 242 that communicate with the second transmission channel 241 at intervals. The collar mounting member 230 is rotatably sleeved on the second transmission pipe 240 so that the first opening 231 and the second opening 242 are connected in a one-to-one correspondence.

[0047] The cross-section of the second transmission pipe 240 is generally circular. The collar mounting piece 230 is rotatably sleeved on the second transmission pipe 240 and can rotate around the circumference of the second transmission pipe 240. The collar mounting piece 230 is connected to the outer wall of the middle part of the first transmission pipe 220. The paint can flow from the first opening 231 along the first transmission channel 221 to the spraying parts 222 at both ends of the first transmission pipe 220.

[0048] In some embodiments of the present invention, the spraying module 200 is further provided with a plurality of drive components 300 corresponding one-to-one with the first transmission pipe 220. The drive components 300 are disposed on the base frame 210, and each drive component 300 drives the corresponding first transmission pipe 220 to swing.

[0049] Each drive assembly 300 individually drives a first transmission tube 220 to swing, thereby adjusting the position of the first transmission tube 220, which can be used to spray the outer wall of the tube 500 at different positions in the circumferential direction.

[0050] In some embodiments of the present invention, the drive assembly 300 includes a motor 310, a drive gear 320, and a driven rack 330. The motor 310 is disposed on the base frame 210, and the driven rack 330 is disposed on the outer peripheral wall of the collar mounting member 230. The drive gear 320 and the driven rack 330 mesh, and the motor 310 is connected to the drive gear 320 to drive the collar mounting member 230 to rotate on the second transmission pipe 240.

[0051] In some embodiments of the present invention, an elastic sealing ring is provided between the inner sidewall of the collar mounting member 230 and the outer peripheral wall of the second transmission pipe 240. The elastic sealing ring can be made of rubber or resin material, has good sealing performance, prevents the coating from leaking from the inner sidewall of the collar mounting member 230 and the outer peripheral wall of the second transmission pipe 240, and can also effectively prevent external moisture or dust from entering the interior.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
