[0003] According to the search, the publication (announcement) No. CN216539137U discloses an anticorrosive paint brush coating device for anticorrosive pipeline production, which discloses the technical scheme of "driving the fixed component by manual operation of the driving component, so that the pipeline is installed on the fixed component and rotated under the operation of the fixed component, the paint on the rotating pipeline can be sprayed by the spraying component, and the paint on the rotating pipeline can be brushed by the scraping component, so as to brush the surface of the pipeline".

[0004] In the above-mentioned scheme, the paint generated in the process of spraying and brushing the pipeline falls into the collection box below for collection, but a part of the falling paint will directly splash on the driving component above the collection box, so that a large amount of paint adheres to the driving component, causing the threaded rod and the base to fail to cooperate, and affecting the normal driving use.

A spraying and brushing mechanism 5 is provided on the bracket 4 for spraying and brushing paint onto the pipeline. A fixing mechanism 6 is provided on the workbench 1 for fixing the pipeline. The spraying and brushing mechanism 5 includes:

[0026] The painting assembly 51 includes a frame 511 fixed on a bracket 4, a circular block 512 rotatably installed inside the frame 511, a connecting rod 514 installed at the bottom of the frame 511, a guide rod 515 installed at the output end of the connecting rod 514, and the guide rod 515 is slidably installed inside the circular block 512. A brush head 516 is fixed at the bottom of the circular block 512 and used to paint the pipe.

[0027] The painting assembly 52 includes a mounting bracket 521 fixed to the top of the frame 511, on which a spray nozzle 522 is mounted for spraying the pipes.

[0028] In this embodiment, the output end of 513 drives the connecting rod 514 to rotate. The connecting rod 514 drives the circular block 512 to rotate back and forth slightly through the guide rod 515. The guide rod 515 slides along the inside of the circular block 512, thereby driving the brush head 516 to swing back and forth to paint the pipe through the circular block 512 that rotates back and forth slightly. At the same time, the spray head 522 is connected to the spray painting machine to spray paint the pipe.

[0029] Specifically, the fixing mechanism 6 includes a positioning frame 61 that is longitudinally slidably mounted on the workbench 1. A first bushing 62 is rotatably mounted on the positioning frame 61. A lower positioning head 63 is inserted into the first bushing 62 and used to position the lower end of the pipe. The lower positioning head 63 is fixed to the first bushing 62 by bolts. A second bushing 64 is rotatably mounted on the upright frame 2. An upper positioning head 65 is inserted into the second bushing 64 and used to position the upper end of the pipe. The upper positioning head 65 is fixed to the second bushing 64 by bolts. A knob screw 66 is threadedly mounted on the front end of the workbench 1. The upper end of the upper positioning head 65 is rotatably mounted to the upper end of the positioning frame 61. A drive mechanism 7 is mounted on the upright frame 2 and used to rotate the fixed pipe.

[0030] In this embodiment, by placing the pipe on the lower positioning head 63, the lower positioning head 63 is inserted into the lower end of the pipe. Then, rotating the knob screw 66 drives the positioning frame 61 to rise. At the same time, the positioning frame 61 drives the pipe on the lower positioning head 63 to rise upward through the first bushing 62 until the upper positioning head 65 is inserted into the upper end of the pipe. Thus, the pipe can be fixed by the lower positioning head 63 cooperating with the upper positioning head 65.

[0031] Specifically, the drive mechanism 7 includes a second motor 71 installed at the bottom of the upper end of the upright 2, a drive pulley 72 installed at the output end of the drive mechanism 7, a driven pulley 73 installed on the upper outer wall of the second bushing 64, and a belt 74 installed between the driven pulley 73 and the drive pulley 72.

[0032] In this embodiment, the output end of the second motor 71 drives the active pulley 72 to cooperate with the belt 74 to drive the driven pulley 73 to rotate, so that the driven pulley 73 can drive the pipe fixed by the fixing mechanism 6 to rotate, thereby enabling the spraying mechanism 5 to spray the pipe at different angles.

[0033] Specifically, a collection tray 8 is fitted onto the lower positioning head 63 to collect paint that falls off during the brushing process;

[0034] In this embodiment, the paint generated during the spraying process is collected by the collection tray 8 to prevent it from falling into other locations and causing problems. Furthermore, the lower positioning head 63 can be disassembled and assembled together with the collection tray 8 for easy replacement.

[0035] Specifically, the linear guide rail 3 is installed on the rear end surface of the upright frame 2, the bracket 4 is installed on the slider of the linear guide rail 3, and the linear guide rail 3 is installed with the spray brush mechanism 5 through the bracket 4 and is used to control the spray brush mechanism 5 to lift and lower.

[0036] In this embodiment, the spray brush mechanism 5 is automatically controlled to lift and lower, so that the pipe can be sprayed at any height.

[0037] The working principle and usage process of this utility model are as follows: First, by placing the pipe on the lower positioning head 63, the lower positioning head 63 is inserted into the lower end of the pipe. Then, the knob screw 66 is rotated to drive the positioning frame 61 to rise. At the same time, the positioning frame 61 drives the pipe on the lower positioning head 63 to rise upward through the first bushing 62 until the upper positioning head 65 is inserted into the upper end of the pipe. Thus, the pipe can be fixed by the lower positioning head 63 and the upper positioning head 65.

[0038] Then, the output end of the second motor 71 drives the active pulley 72 to cooperate with the belt 74 to drive the driven pulley 73 to rotate, so that the driven pulley 73 can drive the pipe fixed by the fixing mechanism 6 to rotate; at the same time, the spray brush mechanism 5 on the bracket 4 is driven to rise and fall by the linear guide rail 3.

[0039] Finally, the spray gun is connected to the nozzle 522 to spray paint the pipe. At the same time, the output end of 513 drives the connecting rod 514 to rotate. The connecting rod 514 drives the circular block 512 to rotate back and forth slightly through the guide rod 515. The guide rod 515 slides along the inside of the circular block 512, thereby driving the brush head 516 to swing back and forth to paint the pipe through the small-amplitude rotation of the circular block 512.
