[0026] like Figure 1 to Figure 5As shown, a laser cleaning device for the inner wall of a ductile iron pipe mold comprises a roller mechanism 2 for supporting the pipe mold 1, and a track mechanism 3 arranged behind the pipe mold 1, wherein the track mechanism 3 is provided with a movable track trolley 4, and the moving direction of the track trolley 4 is parallel to the central axis of the pipe mold 1; the track trolley 4 is provided with a forward extending cross bar 6, and the total length of the cross bar 6 is not shorter than the axial length of the pipe mold 1, and the end of the cross bar 6 is connected to a laser generator 8 via an adjustable connecting frame 7.

[0027] The laser cleaning device for the inner wall of the ductile iron pipe mold can automatically clean the inner wall of the pipe mold, thereby reducing the labor intensity of workers and having high cleaning efficiency and good cleaning quality.

[0028] The laser cleaning device for the inner wall of the ductile iron pipe mold can enable the laser generator 8 to perform cleaning work by transforming points into lines and lines into surfaces through the arrangement of the roller mechanism 2 and the rail trolley 4, and the operation is precise without damaging the inner wall of the pipe mold.

[0029] Specifically, the roller mechanism 2 supports the tube mold 1 as a supporting mechanism on the one hand, and can drive the tube mold 1 to rotate on the other hand, so that the laser generator 8 can be kept in one position to complete the full circle cleaning of the tube mold 1 without controlling the circumferential movement of the laser generator, which is conducive to maintaining the stability of the laser generator, making the cleaning effect and quality better and more stable. The track trolley 4 can move horizontally along the track mechanism, so as to drive the laser generator 8 to extend into the inner cavity of the tube mold 1 and move along the length direction of the tube mold, so that the inner circumference of the tube mold can be cleaned circle by circle.

[0030] Connecting the laser generator 8 through the crossbar 6 and the connecting frame 7 allows the laser generator 8 to be closer to the inner wall of the tube mold, making it easier to clean it. It can also increase the flexibility of the laser generator, allowing it to adapt to tube molds of different types and sizes, thereby increasing the scope of application of the device.

[0031] The laser cleaning device for the inner wall of the ductile iron pipe mold can be used stably for a long time, has low operating costs, and only requires electricity per hour. It also reduces labor intensity and labor costs.

[0032] The laser generator 8 can output laser light, can accurately locate the surface of the cast iron part, quickly remove burrs, flash and oxide scale without damaging the surrounding main body material, and is very suitable for cleaning cast pipes; compared with traditional chemical or physical cleaning methods, laser cleaning is more environmentally friendly, does not require chemical agents, and the waste is powder and is easy to recycle.

[0033] Furthermore, the roller mechanism 2 includes a plurality of groups of rollers arranged at intervals, at least one group of rollers is an active roller, and the active rollers are connected to a driving motor. After the active rollers are started, they can drive other driven rollers and the tube mold to rotate.

[0034] Furthermore, the track mechanism 3 includes a pair of parallel guide rails, at least one of which is provided with a proximity switch 10 at both ends, and a limiter is also provided on the guide rail. The proximity switch 10 can monitor the moving position of the track trolley 4 in real time, and can limit the track trolley 4 in conjunction with the limiter.

[0035] Furthermore, the track trolley 4 is installed on the track mechanism 3 through a roller 401 or a slider, and the track trolley 4 can be driven by a stepper motor; a mounting seat 5 is provided above the track trolley 4, and the cross bar 6 is detachably connected to the mounting seat 5, for example, by bolt connection, to facilitate the replacement of the cross bar 6.

[0036] Furthermore, the rail trolley 4 drives the cross bar 6 to move in steps in the tube mold 1, and the amplitude of each stepping movement does not exceed the laser width of the laser generator 8, so as to ensure that the inner wall of the tube mold 1 can be cleaned circle by circle each time the laser is moved.

[0037] Furthermore, the connecting frame 7 is an angle adjustment bracket to adjust the direction and angle of the laser generator.

[0038] The angle adjustment bracket can be a mature product available on the market, or it can be designed and manufactured by itself. For example, the angle adjustment bracket includes a hinge seat connected to the cross bar, the hinge seat is connected to an ear plate through a hinge axis, the ear plate is connected to a clamping arm, and the laser generator is clamped and fixed by the clamping arm.

[0039] Furthermore, the laser cleaning device also includes a dust removal system arranged in front of the tube mold 1, and the dust removal system includes a dust hood 9 arranged opposite to the tube mouth of the tube mold 1, and the dust hood 9 is connected to a negative pressure pipeline, and the diameter of the dust hood 9 is larger than the diameter of the tube mouth. The dust hood 9 can absorb the dust and smoke generated during the cleaning process of the laser generator 8, avoiding dust on site and making the working environment on site better.

[0040] Furthermore, the laser cleaning device also includes a PLC controller, the PLC controller is connected to a touch screen, and the roller mechanism, the driving motor of the rail trolley, and the controller of the laser generator are all electrically connected or communicatively connected to the PLC controller. The PLC controller and the touch screen can control these moving parts to move according to instructions, and complete the corresponding cleaning work according to the cleaning process and time set for different pipe molds.

[0041] A cleaning method of the laser cleaning device for the inner wall of the ductile iron pipe mold is as follows:

[0042] Place the pipe mold 1 on the roller mechanism 2, input the pipe mold size on the touch screen and transmit it to the PLC controller, and the PLC controller transmits the parameters set for this model of pipe mold to each execution component;

[0043] The rail trolley 4 is started to deliver the laser generator 8 to the port of the tube mold 1; the connecting frame 7 is adjusted so that the laser generator 8 at the end of the cross bar acts on the inner wall of the tube mold 1;

[0044] The roller mechanism 2 is started, and the roller mechanism 2 drives the tube mold 1 to rotate in a circle, and the laser generator 8 starts the cleaning work; after the tube mold 1 rotates one circle, the rail trolley 4 performs stepping motion, and the stepping distance is equal to the laser width of the laser generator, so that the inner wall of the tube mold 1 is cleaned by the stepping motion; while the laser generator 8 starts the cleaning work, the PLC controller starts the dust removal system to collect dust according to the switch signal fed back by the touch screen;

[0045] After the cleaning is completed, the rail trolley 4 returns to the initial position, and the roller mechanism 2 stops rotating, and then the pipe mold 1 is grabbed to enter the next process, and the next pipe mold is grabbed onto the roller mechanism 2 at the same time.
