Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete product polishing, in particular to a surface polishing and cleaning device for concrete products. BACKGROUND

[0002] After demolding, concrete products such as square piles, pipe piles, and prefabricated components often have burrs, floating slurry, or unevenness, etc. on the surface, which need to be polished and cleaned to ensure the appearance quality and dimensional accuracy, and facilitate subsequent construction and installation.

[0003] The existing surface treatment method relies on manual operation of an angle grinder, which is labor-intensive, inefficient, and unstable in polishing quality, and is prone to over-polishing or damage to the product surface. Although some automated equipment can achieve basic polishing of flat surfaces or regular curved surfaces, it has poor adaptability when facing products with different cross-sectional shapes (such as circular, rectangular) or complex structures with grooves or holes on the side. These devices usually cannot quickly and accurately center different sizes of products, and cannot adaptively fit the concave parts with the polishing tool, resulting in incomplete cleaning effect. In addition, if the dust and debris generated during polishing are not collected and treated in time, it will cause environmental pollution. Therefore, there is an urgent need for a device that can automatically adapt to different specifications and complex shapes of concrete products, and achieve efficient, accurate, and clean surface polishing and cleaning.

[0026] Working principle: Before polishing: first step, the corresponding first product 31 or second product 32 material is placed on the upper side of the conveying frame 12, and the first electric push rod 16 is pushed and pulled to move the matching frame 152 to the position, so that the movable wheel 151 is constrained to slide in the constraint frame 15, the first lifting frame 13 and the second lifting frame 14 are cross-cutting and cross-lifting, the conveying frame 12 can drive the first product 31 or the second product 32 to adjust the height position, so that the center position of the first product 31 or the second product 32 corresponds to the center position of the matching groove 221; Second step, after loosening the bolt 19, the first movable frame 182 can move in two directions inside the fixed rod 18, so that the constraint plate 17 can be constrained to the side of the first product 31 or the second product 32, then after tightening the bolt 19, the fixed rod 18 and the first movable frame 182 can be locked and fixed, and the constraint plate 17 can constrain the center position of the first product 31 or the second product 32 to completely correspond to the center position of the first motor 241; When polishing: first step, side polishing, the first product 31 or the second product 32 is conveyed by the conveying frame 12 to the inner side of the working cylinder 21 through the matching groove 221, the first motor 241 drives the gear 24 on the side of the first group of mounting plates 22 to engage with the drive plate 23, the guide block 232 is constrained to slide in the guide slot 231, the connecting frame 233 is connected to slide in the sliding groove 223, so that the movable plate 25 is close to the operation, at this time, the corresponding polishing belt 257 can be close to the side of the first product 31 or the second product 32, the roller frame 255 is pulled to make the second movable frame 252 slide in the third movable slot 251 supported by the elastic support cylinder 254, the polishing belt 257 is elastically close to the side of the first product 31 and the second product 32, and the second motor 256 drives the roller frame 255 to rotate to make the polishing belt 257 polish the side of the first product 31 or the second product 32; Similarly, the same operation is performed on each part on the side of the second group of mounting plates 22, so that the other side of the first product 31 or the second product 32 can be polished; Wherein the electric slide 261 drive makes the electric clamp jaw 27 center to the inside of the polishing belt 257, the electric clamp jaw 27 makes the clamping frame 28 away from the appropriate position, the second electric push rod 262 pushes the electric clamp jaw 27, that is, the support roller shaft 29 is adhered to the inside of the polishing belt 257; When the first product 31 is polished, the support roller shaft 29 can ensure that the inside of the polishing belt 257 is supported by multiple points, so that the polishing belt 257 can better deform and adhere to the side of the first product 31; When the second product 32 is polished, the support roller shaft 29 can ensure that the inside of the polishing belt 257 is supported, so that the polishing belt 257 adheres to the side of the second product 32, which ensures the polishing effect of the side of the first product 31 and the second product 32; In addition, when the support roller shaft 29 supports the inside of the polishing belt 257, the movable block 282 slides in the slot 281 and deforms the support spring 284, and the pressure generated by the support spring 284 is detected by the detection block 283, so that whether the support roller shaft 29 is in place can be determined; The second step is polishing and cleaning. When the first product 31 or the second product 32 is polished, the external water supply module is used for pressurized water supply. The water flow passes through the inside of the ring frame 211 and is sprayed in multiple directions by the spray head 212, so that the side of the first product 31 or the second product 32 can be washed and cleaned. The waste liquid after washing flows out of the discharge slot 213 through the working cylinder 21, and finally flows into the collection box 214 for centralized collection. The third step is shown in the figure Figure 14 The special-shaped matching polishing is used when the first product 31 or the second product 32 has a clamping groove 33. When the polishing belt 257 normally polishes, it reaches the position of the clamping groove 33. Through the input of data in advance, the external controller controls the electric slide 261 to drive the electric clamp jaw 27 to move to the center of the corresponding clamping groove 33. The electric clamp jaw 27 controls the clamping frame 28 to make the support roller shaft 29 correspond to the position of the two walls of the clamping groove 33. Then the second electric push rod 262 pushes the electric clamp jaw 27 to make the support roller shaft 29 actively extrude the inside of the polishing belt 257, so that the polishing belt 257 adheres to the wall surface of the clamping groove 33. The pressure change is detected by the detection block 283 to know that the polishing belt 257 is in place. The second motor 256 drives the roller frame 255 to drive the polishing belt 257 to rotate, so that the polishing operation of the clamping groove 33 can be completed.
