[0058] The automatic device for rust removal on the surface of the iron cylinder provided by the embodiment of the present invention adopts the method of driving the iron cylinder 4 to rotate by the rotation of the driving wheel 31 and cooperating with the linear motion scanning of the laser cleaning head 24, and adopts an approximate spiral trajectory to realize the removal of rust on the surface of the cylindrical workpiece. The whole process can be completed automatically, with high working efficiency. Compared with the prior art, a large amount of labor is saved.

[0059] In one embodiment, the automatic device for rust removal on the surface of the iron cylinder provided by the present invention further includes: a frame 1;

[0060] The cleaning head transmission assembly and the laser cleaning head assembly are arranged on the upper part of the frame 1, and the support wheel assembly is arranged on the lower part of the frame 1.

[0061] In one embodiment, referring to Figure 3 the top view of the automatic device for rust removal on the surface of the iron cylinder shown, the first reduction motor 11 is arranged at the leftmost side of the frame 1. From left to right is the axial placement direction of the iron cylinder 4. The first reduction motor 11 can be set with one-stage or multi-stage transmission according to the matching of the speed of the synchronous belt 17 and the rotation speed of the output shaft of the first reduction motor 11.

[0062] The synchronous belt 17 is arranged from the left side to the right side and realizes transmission by meshing with the first synchronous belt pulley 15 and the second synchronous belt pulley 16.

[0063] The first reduction motor 11 and the first synchronous belt pulley 15 are arranged at one end of the frame 1; the first synchronous belt pulley 15 is connected to the output end of the first reduction motor 11;

[0064] The second synchronous belt pulley 16 is arranged at the other end of the frame 1. The first synchronous belt pulley 15 and the second synchronous belt pulley 16 are arranged along the direction parallel to the axis of the iron cylinder 4;

[0065] The first synchronous belt pulley 15 and the second synchronous belt pulley 16 are meshed with the synchronous belt 17.

[0066] Figure 3Shown is an example where the first synchronous pulley 15 is not directly connected to the output end of the first reduction motor 11. The output end of the first reduction motor 11 is connected to the first synchronous pulley 15 through a smaller synchronous belt ( Figure 3 not shown in the figure); those skilled in the art can imagine that if the speed of the output end of the first reduction motor 11 matches the rotational speed required for the synchronous belt 17 between the first synchronous pulley 15 and the second synchronous pulley 16, the output end of the first reduction motor 11 can also be directly connected to the first synchronous pulley 15 to drive the synchronous belt 17 to move.

[0067] The specific structures of the first synchronous pulley 15, the second synchronous pulley 16, and the synchronous belt 17 can refer to the prior art.

[0068] In one embodiment, the synchronous belt 17 is connected to the first connecting plate 14 through a toothed plate 25. When the synchronous belt 17 is connected to the first connecting plate 14 through the toothed plate 25, the movement of the synchronous belt 17 can drive the first connecting plate 14 to move.

[0069] The first connecting plate 14 is connected to the laser cleaning head assembly. Therefore, the movement of the synchronous belt 17 will drive the first connecting plate 14 and the laser cleaning head assembly to move back and forth in a direction parallel to the axis of the iron cylinder 4 above the iron cylinder 4 to be derusted.

[0070] In one embodiment, referring to Figure 1 shown, the above-mentioned automatic device for derusting the surface of the iron cylinder may further include: a lifting cylinder 36 arranged beside the supporting wheel assembly; wherein:

[0071] The lifting cylinder 36 can be lifted and lowered to lift the iron cylinder 4 and place it on the driving wheel 31 and the driven wheel 32.

[0072] After the lifting cylinder 36 rises to lift the iron cylinder 4 and place it on the driving wheel 31 and the driven wheel 32, the lifting cylinder 36 descends without affecting the rotation of the iron cylinder 4.

[0073] Furthermore, the output end of the lifting cylinder 36 is also connected with a V-shaped block (not shown in the figure), and the V-shaped block is used to support the iron cylinder 4.

[0074] The V-shaped opening part of the V-shaped block is in direct contact with the outer wall of the iron cylinder 4, making the iron cylinder 4 more stable and not easy to fall during the lifting process.

[0075] In one embodiment, referring to Figure 4 shown, the laser cleaning head assembly specifically includes: a trapezoidal screw adjusting assembly 21, a guide rod 22, a second connecting plate 23, and a laser cleaning head 24; wherein:

[0076] The trapezoidal screw rod adjusting assembly 21 and the guide rod 22 are arranged in parallel. The screw rod 214 of the trapezoidal screw rod adjusting assembly 21 passes through the first connecting plate 14, and the upper end of the guide rod 22 is fixedly connected to the first connecting plate 14;

[0077] A screw rod nut 215 is arranged on the screw rod 214 of the trapezoidal screw rod adjusting assembly 21, and a linear bearing 216 is arranged on the guide rod 22. One end of each of the two ends of the second connecting plate 23 is sleeved on the screw rod 214 of the trapezoidal screw rod adjusting assembly 21 through the screw rod nut 214, and the other end is sleeved on the guide rod 22 through the linear bearing 216. The second connecting plate 23 is fixedly connected to the laser cleaning head 24, so that the height of the laser cleaning head 24 can be adjusted up and down through the trapezoidal screw rod adjusting assembly 21 and the guide rod 22.

[0078] For the specific structure of the trapezoidal screw rod adjusting assembly 21, reference can be made to Figure 4 as shown, which includes components such as a handwheel 211, a position display 212, an anti-rotation fixing member 213, and a screw rod 214, etc. The trapezoidal screw rod adjusting assembly 21 of the screw rod 214 can conveniently adjust the height of the laser cleaning head, and can better adapt to iron cylinders 4 with different diameters. For iron cylinders 4 with different diameters, only the laser cleaning head needs to be moved up and down for focusing, which is convenient to operate and has a wider application range.

[0079] In one embodiment, with reference to Figure 1 as shown, the above-mentioned support wheel assembly further includes: a third synchronous belt pulley 34, a fourth synchronous belt pulley 35, and a coupling (not shown in the figure);

[0080] The third synchronous belt pulley 34 is rotatably arranged on the long shaft 37;

[0081] The output shaft of the second reduction motor 33 is connected to the fourth synchronous belt pulley 35 through a coupling;

[0082] The third synchronous belt pulley 34 and the fourth synchronous belt pulley 35 are connected by a synchronous belt (not shown in the figure).

[0083] The driving wheel 31 is used to support and drive the iron cylinder 4 to rotate. The driven wheel 32 serves a similar role as the driving wheel 31 in supporting the iron cylinder 4 on the one hand, and on the other hand rotates passively during the rotation of the iron cylinder 4, making the rotation of the iron cylinder 4 smoother.

[0084] Both the driving wheel 31 and the driven wheel 32 can adopt polyurethane structural wheels.

[0085] Since during the process of laser scanning and rust removal on the surface of the iron cylinder 4, sparks and splashed slag may be generated, for operation safety and environmental cleanliness, the automatic device for iron cylinder surface rust removal provided by the present invention may further include: a movable door 2 that can move up and down; wherein:

[0086] The moving door 2 is used to open when the iron cylinder 4 enters the automatic device for rust removal on the surface of the iron cylinder, and to close during the process of the iron cylinder 4 rotating on the support wheel assembly for rust removal.

[0087] Since the moving door 2 can move up and down, for the convenience of labor-saving upward movement, preferably, referring to Figure 3 as shown, the above-mentioned automatic device for rust removal on the surface of the iron cylinder further includes: a counterweight chain 3; wherein: the counterweight chain 3 is connected to the upper end of the moving door 2.

[0088] The working process of the automatic device for rust removal on the surface of the iron cylinder provided by the present utility model is briefly described as follows:

[0089] The moving door 2 moves upward to open. After the iron cylinder 4 is moved to the upper part of the support wheel assembly through an external support frame, the lifting cylinder 36 lifts the iron cylinder 4. The lifting cylinder 36 descends, places the iron cylinder 4 on the support wheel assembly, and then the moving door 2 falls to close, and the rust removal operation starts.

[0090] The laser cleaning head assembly is driven by the synchronous belt 17 to perform uniform linear scanning, gradually scanning from one end of the iron cylinder 4 to the other end. At the same time, it rotates at a preset speed. The linear movement speed of the laser cleaning head assembly matches the rotation speed of the iron cylinder 4, so that for every movement of one scanning width by the laser cleaning head 24, the iron cylinder 4 rotates one week, and the laser cleaning head 24 scans the entire surface of the iron cylinder 4 in an approximately spiral trajectory, achieving the purpose of overall rust removal on the outer surface of the iron cylinder 4.

[0091] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these changes and modifications.
