Description

Technical Field

[0001] This utility model relates to the field of cabinet processing, and in particular to a surface treatment device for steel plates. Background Technology

[0002] The surface grinding device for steel filing cabinets is a specialized piece of equipment designed specifically for treating the surface of steel plates, removing defects, and laying a smooth base for subsequent coating and other processes. It typically consists of a drive system, grinding execution components, a positioning and clamping mechanism, a dust removal system, and a control system. During operation, the steel plate to be processed is first fixed by the positioning mechanism to prevent displacement during grinding and thus accuracy deviations. Then, the drive system drives the grinding components to contact the steel plate surface at a set speed and pressure, specifically removing residual oxide scale, rust, burrs from stamping or cutting, scratches, and surface unevenness. Simultaneously, the dust removal system removes the metal dust generated during grinding, reducing dust pollution and ensuring a clean grinding surface. Some devices also have speed and direction adjustment functions, allowing adjustment of grinding parameters according to the steel plate thickness, the degree of surface defects, and subsequent processing requirements. This ensures the steel plate surface achieves a uniform roughness and is free of obvious defects, providing a good adhesion base for subsequent phosphating, spraying, and other surface treatment processes, thus improving the appearance quality and corrosion resistance of the steel filing cabinet.

[0003] In the prior art, compared with the Chinese utility model with announcement number CN218082018U, a cabinet surface finishing device is disclosed, which polishes the surface of the filing cabinet through multiple polishing methods. However, in the actual processing, it was found that some steel plates will undergo oxidation after the initial processing and some burrs will still exist during transportation. Under the same polishing environment, it is impossible to guarantee that areas with many burrs or rust spots can be effectively treated, so further processing is required, which affects the processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a surface treatment device for steel plates in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A surface treatment device for steel plates includes a conveying mechanism and a dust removal mechanism, and further includes a grinding mechanism for grinding the steel plates and a hardness adjustment mechanism for adjusting the grinding mechanism. The grinding mechanism is provided with a sealing shell on the outside, and the dust removal mechanism is provided on both sides of the grinding mechanism. The grinding mechanism includes a drive shaft and a driven shaft. The two ends of the driven shaft are connected to the hardness adjustment mechanism, and a grinding sand roll is provided on the outside between the drive shaft and the driven shaft.

[0007] The stiffness adjustment mechanism includes a connecting shaft, which is fixedly connected to the passive shaft. An inner frame is rotatably connected to the outside of the connecting shaft. An extrusion block is connected to the upper side of the inner frame via an elastic element. A sliding frame is provided around the inner frame and the extrusion block. The inner frame is slidably connected to the inner side of the sliding frame. A fixed frame is provided on the outer side of the sliding frame. The sliding frame is slidably connected to the inner side of the fixed frame. An extrusion assembly is provided between the top of the sliding frame and the fixed frame. A spring is provided on the sliding frame corresponding to the discharge end.

[0008] Preferably, the extrusion assembly includes a limiting groove and an extrusion strip. The extrusion strip is a wedge-shaped strip and is installed laterally on the top inner side of the fixed frame. The sliding frame is formed with a limiting groove that cooperates with the sliding of the extrusion strip. The top surface of the extrusion block corresponds to the limiting groove.

[0009] Preferably, the distance between the inner frame and the extrusion block is equal to the maximum height of the extrusion strip.

[0010] Preferably, the lateral sliding distance of the sliding frame is the radius of the passive shaft.

[0011] Preferably, the fixing frame is fixedly connected to the sealing shell by bolts.

[0012] Preferably, the upper and lower end faces of the inner side of the fixed frame are provided with slots, and the upper and lower end faces of the sliding frame are provided with blocks corresponding to the slots, and the blocks are slidably connected to the slots.

[0013] Preferably, the dust removal mechanism includes a smoke exhaust port and a dust collection pipe, the dust collection pipe having a conical structure and being disposed on both sides of the sanding roll.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By adding an extrusion assembly between the inner frame and the extrusion block, when encountering numerous burrs and rust spots on the surface of the sheet metal, the counterforce of the burrs and rust spots causes the sliding frame to slide. After the sliding frame, inner frame, and extrusion block slide, the extrusion assembly increases the extrusion force of the extrusion block on the inner frame. With the height of the passive shaft remaining unchanged, this increases the grinding force of the passive shaft on the sheet metal. At the same time, due to the lateral displacement of the passive shaft, the relative distance between the passive shaft and the active shaft increases, and the grinding sand roll is straightened, improving the treatment effect on burrs and rust spots. After treating this area, the elastic element is used to reset the area to avoid affecting the processing of subsequent areas. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-7 As shown, a surface treatment device for steel plates includes a conveying mechanism 3 and a dust removal mechanism 2, as well as a grinding mechanism 1 for grinding the steel plate and a soft-hardness adjustment mechanism 4 for adjusting the grinding mechanism 1. The grinding mechanism 1 is provided with a sealing shell on the outside, and the dust removal mechanism 2 is provided on both sides of the grinding mechanism 1. The grinding mechanism 1 includes a drive shaft 12 and a passive shaft 13. The soft-hardness adjustment mechanism 4 is connected to both ends of the passive shaft 13. A grinding sand roll 14 is provided on the outside between the drive shaft 12 and the passive shaft 13.

[0030] The soft / hard adjustment mechanism 4 includes a connecting shaft 45, which is fixedly connected to a passive shaft 13. An inner frame 43 is rotatably connected to the outside of the connecting shaft 45. An extrusion block 44 is connected to the upper side of the inner frame 43 through an elastic element 46. A sliding frame 42 is provided to wrap around the inner frame 43 and the extrusion block 44. The inner frame 43 is slidably connected to the inside of the sliding frame 42. A fixed frame 41 is provided on the outside of the sliding frame 42. The sliding frame 42 is slidably connected to the inside of the fixed frame 41. An extrusion assembly is provided between the top of the sliding frame 42 and the fixed frame 41. A spring is provided on the sliding frame 42 corresponding to the discharge end.

[0031] Preferably, the extrusion assembly includes a limiting groove 47 and an extrusion strip 48. The extrusion strip 48 is a wedge-shaped strip and is horizontally installed on the top inner side of the fixed frame 41. The sliding frame 42 is formed with a limiting groove 47 that slides with the extrusion strip 48. The top surface of the extrusion block 44 corresponds to the limiting groove 47.

[0032] Preferably, the distance between the inner frame 43 and the extrusion block 44 is equal to the maximum height of the extrusion strip 48, to avoid excessive extrusion and limit the movement.

[0033] Preferably, the lateral sliding distance of the sliding frame 42 is the radius of the passive shaft 13.

[0034] Preferably, the fixing frame 41 is fixedly connected to the sealing shell by bolts to ensure the fixing effect of the fixing frame 41.

[0035] Preferably, the upper and lower end faces of the inner side of the fixed frame 41 are provided with slots, and the upper and lower end faces of the sliding frame 42 are provided with corresponding slots with blocks. The blocks slide to connect with the slots to prevent the sliding frame 42 from dislodging.

[0036] Preferably, the dust removal mechanism 2 includes a smoke outlet 21 and a dust collection pipe 22. The dust collection pipe 22 has a conical structure and is arranged on both sides of the sanding roll 14.

[0037] Working principle: The starting motor drives the drive shaft 12 to rotate, which in turn drives the passive shaft 13 to rotate through the grinding sand roll 14. The plate is conveyed through the piercing mechanism 5 for grinding. Under normal grinding conditions, when the passive shaft 13 encounters the plate, the downward pressure provided by the elastic element 46 tends to stabilize, thereby ensuring the downward pressure of the passive shaft 13 on the grinding sand roll 14, thus grinding the plate.

[0038] When there are large areas of burrs or rust spots on the plate, the friction between the rust spots and the sanding roll 14 increases, and the relative compression on the passive shaft 13 also increases. After the compression increases, some of the force will push the sliding frame 42 to slide inside the fixed frame 41. When the sliding frame 42 slides, the inclined surface of the extrusion strip 48 on the top of the extrusion block 44 presses against the extrusion block 44, and the extrusion block 44 will be pressed down. After the extrusion block 44 is pressed down, the elastic element 46 is compressed, and the downward pressure toughness of the connecting shaft 45 fixed inside the inner frame 43 becomes harder, so the downward pressure toughness of the passive shaft 13 also becomes harder. At the same time, due to the lateral displacement of the passive shaft 13, the relative distance between the passive shaft 13 and the active shaft 12 increases, and the sanding roll 14 is straightened, which improves the treatment effect of burrs and rust spots. After this area is treated, it is reset by the elastic element to avoid affecting the processing of subsequent areas.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
