Description

Technical Field

[0001] The utility model relates to the technical field of plastic-dipped pipe production, in particular to a coating machine. Background Art

[0002] During the production of plastic-dipped pipes, in order to reduce the erosion of the external environment on the plastic-dipped pipes, it is necessary to apply paint on the surface of the plastic-dipped pipes. In the process of coating the plastic-dipped pipes, a coating machine is needed. The coating machine is a device that applies paint on the surface of the plastic-dipped pipes during the production of the plastic-dipped pipes. The coating machine mainly consists of a shell component, a connection component, a transmission component and a coating component. The coating machine has the advantages of fast coating speed, convenient coating and simple operation.

[0003] Common coating machines generally have the following defects during use:

[0004] First, before using a common coating machine, in order to fully coat the plastic-dipped tube, the plastic-dipped tube needs to be fixed on the device and rotated. The common way to fix the plastic-dipped tube is to insert a rotating disk that is consistent with the inner diameter of the plastic-dipped tube into the two ends of the plastic-dipped tube, and rotate the rotating disk to achieve the purpose of rotating the plastic-dipped tube. However, since the rotating disk and the plastic-dipped tube are both cylindrical, the plastic-dipped tube will slip during the rotation process, which is not conducive to coating the plastic-dipped tube;

[0005] Second: Common coating machines are used to apply paint directly through the nozzle. Most of the sprayed paint will fall directly on the surface of the plastic-dip tube, but some of the paint will still be sprayed outside the plastic-dip tube, thus affecting other places and hindering the spraying process.

[0006] Third: During the use of common coating machines, the positions of the two rotating disks for fixing the plastic-dipped tubes are fixed, resulting in the coating machine being able to process only plastic-dipped tubes of the same length. When processing plastic-dipped tubes of different lengths, the coating machine cannot meet the needs, and the coating machine has poor applicability;

[0007] In summary, common coating machines generally have defects during use, such as the plastic-dip tube slipping during rotation, some of the sprayed paint being sprayed outside the plastic-dip tube, and only plastic-dip tubes of the same length can be processed, resulting in poor applicability of the coating machine.

The distance between the two support rods 2 can be changed, which is convenient for processing and producing plastic-dip tubes of different lengths;

[0032] The fixing mechanism 4 includes a moving groove 403 provided on the upper side of each rotating block 3, and the interior of the moving groove 403 is slidably connected to two moving blocks 402, and one end of each moving block 402 extends to the outside of the moving groove 403. A fixing plate 401 is fixedly connected to the side of the moving block 402, and a connecting plate 404 is fixedly connected to the interior of the moving groove 403. A double-headed threaded rod 405 is rotatably connected to the upper surface of the connecting plate 404, and the lower end of the double-headed threaded rod 405 passes through the connecting plate 404. The two ends of the double-headed threaded rod 405 are respectively threadedly connected to the two moving blocks 402, and the upper end of the double-headed threaded rod 405 is fixedly connected to the knob 406. The fixing mechanism 4 is provided, which is beneficial for rotating the rotating rod first when the plastic dipping tube needs to be installed and fixed. Button 406, knob 406 drives the double-headed threaded rod 405 to rotate. Since the double-headed threaded rod 405 is threadedly connected to the two moving blocks 402, the double-headed threaded rod 405 rotates to realize that the moving block 402 moves out from the inside of the moving groove 403, so that the moving block 402 drives the fixed plate 401 away from the rotating block 3, and the plastic-dipped tube is placed between the two rotating blocks 3. The electric telescopic rod 608 is started, and the electric telescopic rod 608 drives the two support rods 2 to approach each other, so that the support rod 2 drives the rotating block 3 to move and the two rotating blocks 3 enter the two ends of the plastic-dipped tube, and then the knob 406 is rotated in the opposite direction to realize that the fixed plate 401 clamps and fixes the plastic-dipped tube, so that the plastic-dipped tube will not slip during the processing, which facilitates the processing of the plastic-dipped tube.

By providing the coating mechanism 5, it is beneficial to start the motor 603 when it is necessary to spray the plastic-dipped tube, and the motor 603 drives the power rod 604 to rotate Rotation, since one end of the limiting rod 605 is located inside the limiting groove 607 and the longitudinal sections of both are rectangular, the power rod 604 will drive the transmission rod 606 and the rotating block 3 to rotate, thereby realizing the rotation of the dipping tube, and injecting paint through the feed pipe 505. The paint will enter the nozzle 503 through the connecting pipe 504, and the paint inside the nozzle 503 will be sprayed out. As the dipping tube rotates, the paint will be sprayed onto the surface of the dipping tube, and the paint that has not been sprayed onto the dipping tube will be blocked by the baffle 501, which facilitates spraying.

[0036] In a preferred embodiment, the connecting pipe 504 and the feed pipe 505 are both arranged on the side of the support plate 502 away from the baffle 501. A nozzle is provided at one end of the nozzle 503.

[0039] The working principle of this embodiment is: when the plastic-immersed tube needs to be installed and fixed, first rotate the knob 406, and the knob 406 drives the double-headed threaded rod 405 to rotate. Since the double-headed threaded rod 405 is threadedly connected to the two moving blocks 402, the double-headed threaded rod 405 rotates to realize that the moving block 402 moves out from the inside of the moving groove 403, so that the moving block 402 drives the fixed plate 401 away from the rotating block 3, and the plastic-immersed tube is placed between the two rotating blocks 3, and the electric telescopic rod 608 is started. The electric telescopic rod 608 drives the two support rods 2 to move closer to each other, so that the support rod 2 drives the rotating block 3 to move and realizes that the two rotating blocks 3 enter the two ends of the plastic-immersed tube, and then rotates the knob 406 in the opposite direction to realize that the fixed plate 401 clamps and fixes the plastic-immersed tube, so that the plastic-immersed tube will not slip during the processing, which is convenient for processing the plastic-immersed tube;

[0040] When the plastic-dipped tube needs to be sprayed, the motor 603 is started, and the motor 603 drives the power rod 604 to rotate. Since one end of the limiting rod 605 is located inside the limiting groove 607 and the longitudinal sections of both are rectangular, the power rod 604 will drive the transmission rod 606 and the rotating block 3 to rotate, thereby realizing the rotation of the plastic-dipped tube. The paint is injected through the feed pipe 505, and the paint enters the nozzle 503 through the connecting pipe 504. The paint inside the nozzle 503 will be sprayed out. As the plastic-dipped tube rotates, the paint will be sprayed onto the surface of the plastic-dipped tube, and the paint that is not sprayed onto the plastic-dipped tube will be blocked by the baffle 501 to facilitate spraying.
