[0002] Due to processing or assembly requirements, there are various grooves on metal plates. Some of these grooves are located at the edge of the plate, and some are located in the middle. Since these grooves are mostly post-processed, the anti-rust coating often no longer exists. Therefore, before actual application, the groove position needs to be polished and rust-removed.

[0003] There are many ways to grind and remove rust, but the best effect is to use a polishing belt that matches the cross-section of the groove to grind and remove rust on the groove longitudinally; however, different forms of grooves often require different polishing belts to be replaced, so how to quickly and conveniently remove and install the polishing belt is the main technical problem faced by this solution. Summary of the invention

[0046] like Figure 1 to Figure 13 As shown, the present invention proposes a device for removing rust from the groove of a metal plate, comprising a plate fixing mechanism 1, a frame adaptive lifting mechanism 2, a disassembly tightness control mechanism 3 and a rust removal and dust collection mechanism 4, the plate fixing mechanism 1 comprises a base 5 and a plate body 6, the plate body 6 is fixed to the base 5 by bolts, and a special-shaped groove 8 is provided on the plate body 6, the frame adaptive lifting mechanism 2 is slidably arranged on the plate fixing mechanism 1, the disassembly tightness control mechanism 3 is arranged on the frame adaptive lifting mechanism 2, and the rust removal and dust collection mechanism 4 is arranged on the disassembly tightness control mechanism 3.

[0047] Through the frame adaptive lifting mechanism 2, not only can the height of the hollow longitudinal beam 21 be actively adjusted, but also the height of the hollow longitudinal beam 21 can be automatically raised when the polishing belt 38 is disassembled and replaced to leave space for the replacement of the polishing belt 38, and after the polishing belt 38 is replaced, the hollow longitudinal beam 21 can be automatically controlled to descend and reset to the initial height during the tensioning process.

[0049] The tension quick adjustment component 22 includes a square slide 26, a cantilever rotating shaft 27, a tension control strut 28 and a lifting hinge seat 29. A transverse slide groove 24 is provided on the hollow longitudinal beam 21. The square slide 26 is slidably engaged in the transverse slide groove 24. The cantilever rotating shaft 27 is rotatably disposed in the square slide 26. A longitudinal slide groove 25 perpendicular to the transverse slide groove 24 is also provided on the hollow longitudinal beam 21.

One end of the tension control strut 28 is hinged to the cantilever rotating shaft 27, and the other end of the tension control strut 28 is hinged to the lifting hinge seat 29.

[0050] By lifting and sliding the lifting hinge seat 29, the approach and distance between the two cantilevered rotating shafts 27 and the two pulleys 37 can be controlled, thereby changing the tension of the polishing belt 38, creating basic conditions for disassembling and installing the polishing belt 38.

[0051] The tension control assembly 23 includes a hollow box body 30, a lifting top block 31 and a control screw 32. The control screw 32 is rotatably arranged on the top of the hollow longitudinal beam 21. A threaded hole 33 is provided on the lifting hinge seat 29. The control screw 32 and the threaded hole 33 are threadedly connected. The hollow box body 30 is fixedly connected to the top inner wall of the hollow longitudinal beam 21.

[0052] By lifting and lowering the lifting hinge seat 29 and driving the lifting top block 31 to slide, the liquid exchange between the hollow box body 30 and the lifting sleeve 15 can be controlled, so that the height of the hollow longitudinal beam 21 is automatically raised when the polishing belt 38 is loosened and removed, leaving space for replacing the polishing belt 38; when installing and tensioning the polishing belt 38, the height of the hollow longitudinal beam 21 can be automatically lowered to return it to its initial position.

The frame sliding component 9 is slidably arranged on the plate fixing mechanism 1, the lifting execution component 10 is arranged on the frame sliding component 9, and the lifting control component 11 is arranged in the lifting execution component 10.

[0054] Sliding guide rails 7 are symmetrically provided on both sides of the base 5. The frame sliding assembly 9 includes a sliding block 12 and a sliding plate 13. The sliding block 12 is slidably arranged on the sliding guide rail 7, and the sliding plate 13 is arranged on the sliding block 12. The lifting actuator assembly 10 includes a fixed seat 14, a lifting sleeve 15 and a lifting leg 16.

[0055] By overall controlling the extension range of the lifting legs 16 from the lifting sleeve 15, the height of the hollow longitudinal beam 21 relative to the sliding plate 13 can be changed, thereby achieving height adjustment of the entire disassembly tension control mechanism 3 and the rust removal and dust collection mechanism 4, which includes both manual adjustment and automatic adjustment.

[0056] The lifting control assembly 11 includes a piston plate 17, a screw hole bracket 18 and a manual adjustment stud 19. The piston plate 17 is slidably engaged in the lifting sleeve 15. A branch conduit 20 is provided on the piston plate 17. The screw hole bracket 18 is fixedly connected to the top of the lifting sleeve 15. The manual adjustment stud 19 is rotatably arranged on the piston plate 17, and the manual adjustment stud 19 and the screw hole bracket 18 are threadedly connected.

[0057] By rotating the manual adjustment stud 19, the extension range of the lifting leg 16 from the lifting sleeve 15 can be manually adjusted without changing the distance between the piston plate 17 and the lifting leg 16, so as to adapt to the working height required for plates of different thicknesses.

[0058] The rust removal and dust collection mechanism 4 includes a rust removal component 35 , and the rust removal component 35 includes a pulley 37 and a polishing belt 38 . The pulley 37 is fixedly connected to the frame adaptive lifting mechanism 2 , and the polishing belt 38 is arranged on the pulley 37 .

[0059] The rust removal and dust collection mechanism 4 also includes a dust collecting component 36, which includes a dust collecting impeller 39, a dust hood 40 and a fine brush 41. The dust collecting impeller 39 is fixedly connected to the pulley 37 at one end of the hollow longitudinal beam 21. A rust removal motor is provided at the other end of the hollow longitudinal beam 21. The outer casing of the rust removal motor is provided on the square slide seat 26. The output shaft of the rust removal motor is connected to the cantilever rotating shaft 27. The dust hood 40 is fixedly connected to the hollow longitudinal beam 21, and the fine brush 41 is provided below the dust hood 40.

[0060] A filter screen and a dust box are provided inside the dust hood 40, and the impurities in the dust box need to be cleaned regularly.

[0061] A dust collecting duct is provided at the rear of the dust collecting hood 40, through which impurities appearing at the grinding and rust removal location can be continuously transported to an external filtering device.

[0062] The dust collecting impeller 39 can generate a directional airflow to collect the dust generated by rust removal into the dust collecting hood 40, and the fine brush 41 can block one end of the grinding area, thereby significantly reducing the possibility of small particles overflowing.

[0063] When in use, the user first needs to select a polishing belt 38 with a suitable cross-section according to the bevel form on the plate body 6, wherein the special-shaped bevel 8 mainly includes an edge bevel, a right-angle bevel, a V-shaped bevel, an arc bevel, and the like.

[0064] The steps for replacing the polishing belt 38 are as follows:

[0065] First, by rotating the control screw 32, the lifting articulated seat 29 is raised. At this time, through the linkage of the tension control strut 28, the cantilevered rotating shaft 27 and the square slide 26 at both ends will slide close to each other. At this time, due to the reduction in the spacing between the pulleys 37, the original polishing belt 38 will become loose and easy to remove; in this process, since the lifting top block 31 invades the hollow box body 30, the liquid in the hollow box body 30 will enter the piston plate 17 through the main conduit 34 and the branch conduit 20. At this time, although the position of the manual adjustment stud 19 does not move, when the liquid between the lifting leg 16 and the piston plate 17 increases, the lifting leg 16 will continue to extend from the lifting sleeve 15, thereby achieving the technical effect of automatically lifting the hollow longitudinal beam 21.

[0066] After removing the original polishing belt 38, replace it with a new one, and then rotate the control screw 32 in the opposite direction. The two pulleys 37 can be moved away from each other by lowering the lifting hinge seat 29, thereby achieving the tensioning of the polishing belt 38; at the same time, the liquid flowing out of the hollow box body 30 will also flow back, so that the hollow longitudinal beam 21 will be lowered and reset.

[0067] When facing plates of different thicknesses, it is necessary to actively change the height of the hollow longitudinal beam 21. At this time, by rotating the manual adjustment stud 19, the extension range of the lifting legs 16 can be changed while the amount of liquid in the lifting sleeve 15 remains unchanged, thereby achieving active adjustment of the height of the hollow longitudinal beam 21.

[0068] When removing rust, the housing of the rust removal motor is arranged on the square slide 26, and the output shaft of the rust removal motor is connected to the cantilevered rotating shaft 27, so when the rust removal motor is started, the polishing belt 38 will polish and remove rust from the target part by its own movement;

[0069] The overall sliding direction of the frame adaptive lifting mechanism 2 is opposite to the movement direction of the lower part of the polishing belt 38. Therefore, the fine particles polished off will enter the dust collecting hood 40 under the action of the airflow generated by the dust collecting impeller 39. The fine brush 41 can automatically adapt to the grooves of different sizes and can significantly reduce the possibility of small particles overflowing.

[0070] After dust enters the dust collecting cover 40, it is isolated and filtered by the filter and can be cleaned regularly.

[0071] As another new embodiment of the present invention, by providing a dust collecting pipe at the rear of the dust collecting hood 40, impurities appearing at the grinding and rust removal position can be continuously transported to an external filtering device through the dust collecting pipe.

[0072] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0073] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
