For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] As Figures 1-3 shown, the embodiment provides a plate double-sided adaptive cleaning device, which comprises a base 1, the base 1 is provided with a driving mechanism 2 and a polishing execution mechanism 3, the polishing execution mechanism 3 comprises an upper polishing wheel group 31 and a lower polishing wheel group 32 arranged below the upper polishing wheel group 31, the upper polishing wheel group 31 and the lower polishing wheel group 32 are connected with the driving mechanism 2; One side of the polishing execution mechanism 3 is provided with a dynamic pressure and gravity balance mechanism 4 for adjusting the polishing pressure and balancing the gravity of the upper polishing wheel group 31 and the lower polishing wheel group 32, both ends of the dynamic pressure and gravity balance mechanism 4 are connected with the upper polishing wheel group 31 and the lower polishing wheel group 32 respectively. The embodiment synchronously polishes the plate through the upper polishing wheel group 31 and the lower polishing wheel group 32, greatly improves the polishing efficiency, and balances the gravity of the upper polishing wheel group 31 and the lower polishing wheel group 32 through the dynamic pressure and gravity balance mechanism 4 and accurately adjusts the polishing pressure, avoids the problem that the polishing pressure of the upper polishing wheel group 31 and the lower polishing wheel group 32 is too different due to self weight, and the problems of over-polishing or incomplete polishing caused by insufficient pressure control and polishing wheel 33 wear of traditional equipment, improves the polishing quality, so as to realize efficient and high-quality removal of double-sided burrs, slag, rust marks and surface paint layer of steel plates of different thicknesses, which helps to improve the quality and efficiency of steel plate welding, especially suitable for efficient and automatic surface cleaning of burrs, slag, rust marks, oxide skin and the like on the end face of the steel plate to be spliced after processing.

[0030] In some embodiments, two polishing execution mechanisms 3 are symmetrically arranged on the base 1, and one side of each polishing execution mechanism 3 is provided with a dynamic pressure and gravity balance mechanism 4. As Figure 2 and Figure 3 shown, the base 1 is symmetrically provided with two polishing execution mechanisms 3 and two dynamic pressure and gravity balance mechanisms 4, each polishing execution mechanism 3 comprises an upper polishing wheel group 31 and a lower polishing wheel group 32, and both ends of each dynamic pressure and gravity balance mechanism 4 are connected with the upper polishing wheel group 31 and the lower polishing wheel group 32 of the corresponding polishing execution mechanism 3, so as to realize synchronous double-sided polishing of two steel plates to be spliced, which greatly improves the polishing efficiency.

[0031] Furthermore, the dynamic pressure and gravity balance mechanism 4 includes a sliding component 41, a pressure adjustment component 42 for adjusting the grinding pressure, and a gravity balance component 43 for balancing the gravity of the upper grinding wheel assembly 31 and the lower grinding wheel assembly 32. The sliding component 41 includes a fixing member 411 connected to the base 1, an upper sliding member 412 connected to the upper grinding wheel assembly 31, and a lower sliding member 413 connected to the lower grinding wheel assembly 32. The upper sliding member 412 and the lower sliding member 413 are both slidably mounted on the fixing member 411. The two ends of the pressure adjustment component 42 are respectively connected to the upper sliding member 412 and the lower sliding member 413. The two ends of the gravity balance component 43 are respectively connected to the upper sliding member 412 and the lower sliding member 413. By connecting the upper sliding member 412 and the lower sliding member 413 to the upper grinding wheel assembly 31 and the lower grinding wheel assembly 32 respectively, the linear movement of the upper grinding wheel assembly 31 and the lower grinding wheel assembly 32 is ensured. First, the gravity of the upper grinding wheel assembly 31 and the lower grinding wheel assembly 32 is balanced by the gravity balancing component 43, thereby avoiding excessive difference in grinding pressure between the upper grinding wheel assembly 31 and the lower grinding wheel assembly 32 due to their own weight. Then, the grinding pressure is precisely controlled by the pressure adjustment component 42, avoiding the problems of insufficient pressure control and wear of the grinding wheel 33 in traditional equipment. This effectively prevents over-grinding that damages the substrate or incomplete grinding, and improves the grinding quality.

[0032] like Figure 5 As shown, the fixing member 411 is arranged vertically, and the upper sliding member 412 and the lower sliding member 413 are slidably installed on the upper and lower parts of the fixing member 411, respectively, and can slide up and down. The bearing seats 34 of the upper grinding wheel assembly 31 and the lower grinding wheel assembly 32 are fixedly connected to the upper sliding member 412 and the lower sliding member 413, respectively, so that the upper grinding wheel assembly 31 and the lower grinding wheel assembly 32 always move in the vertical direction, ensuring that the pressure applied by the upper grinding wheel assembly 31 and the lower grinding wheel assembly 32 to the plate is collinear and opposite.

[0033] In some embodiments, the pressure adjustment assembly 42 includes a cylinder 421, the movable end and the fixed end of which are connected to the upper sliding member 412 and the lower sliding member 413, respectively. As shown in Figure 3, the cylinder rod at the movable end of the cylinder 421 and the cylinder body at the fixed end are fixedly connected to the upper sliding member 412 and the lower sliding member 413, respectively. By driving the cylinder rod to extend and retract and controlling the air pressure of the cylinder 421, the distance and grinding force of the grinding wheels 33 between the upper grinding wheel assembly 31 and its corresponding lower grinding wheel assembly 32 can be adjusted, thereby achieving precise control of the grinding pressure. This avoids the problems of insufficient pressure control and wear of the grinding wheels 33 in traditional equipment, effectively preventing over-grinding that damages the board or incomplete grinding, and improving the grinding quality.

[0034] In some embodiments, the gravity balance assembly 43 comprises a fixed pulley set 431, a movable pulley 432, a steel wire rope 433, and a balancer 434. The top of the base 1 is provided with two fixed pulley sets 431. One end of the steel wire rope 433 is connected to the upper sliding member 412, and the other end of the steel wire rope 433 is connected to the lower sliding member 413 after winding through one of the fixed pulley sets 431, the movable pulley 432, and the other fixed pulley set 431. The movable pulley 432 is connected to the bottom of the base 1 through the balancer 434. As shown in Figure 6 by adjusting the tension of the balancer 434 to be approximately equal to the weight of the upper grinding wheel set 31 and the lower grinding wheel set 32, the gravity of the upper grinding wheel set 31 and the corresponding lower grinding wheel set 32 can be balanced, thereby avoiding the difference between the grinding pressures of the upper grinding wheel set 31 and the lower grinding wheel set 32 caused by the weight.

[0035] In this embodiment, the upper grinding wheel set 31 and the lower grinding wheel set 32 are connected by a pulley set and a steel wire rope 433, and the weight of the upper grinding wheel set 31 is less than that of the lower grinding wheel set 32. The upper grinding wheel set 31 and the lower grinding wheel set 32 can automatically be in an automatically opened state under the action of gravity, so as to facilitate the placement of the board between the upper grinding wheel set 31 and the lower grinding wheel set 32.

[0036] As shown in Figure 5 The base 1 is provided with a mounting plate 11 for mounting the dynamic pressure and gravity balance mechanism 4, and the mounting plate 11 is arranged in the vertical direction. Each fixed pulley set 431 comprises two fixed pulleys. One of the fixed pulleys has an axle that is perpendicular to the axles of the upper grinding wheel set 31 and the lower grinding wheel set 32 and is fixed to the top of the mounting plate 11. The other fixed pulley has an axle that is parallel to the axles of the upper grinding wheel set 31 and the lower grinding wheel set 32 and is fixed to one side of the mounting plate 11 together with the balancer 434. The fixing member 411 is fixed to the other side of the mounting plate 11. One end of the steel wire rope 433 is fixedly connected to the upper sliding member 412, and the other end of the steel wire rope 433 is fixedly connected to the lower sliding member 413 after reversing through one of the fixed pulley sets 431 and winding through the movable pulley 432 connected to the balancer 434 and the other fixed pulley set 431. Specifically, the two ends of the steel wire rope 433 can be fixedly connected to the upper sliding member 412 and the lower sliding member 413 through steel wire buckles 435, respectively.

[0037] Preferably, the balancer 434 is a tension spring, and the two ends of the tension spring are respectively connected to the bottom of the base 1 and the wheel frame of the movable pulley 432. Alternatively, the balancer 434 is a gas cylinder, and the fixed end and the movable end of the gas cylinder are respectively connected to the bottom of the base 1 and the wheel frame of the movable pulley 432. The gravity balance of the upper grinding wheel set 31 and the corresponding lower grinding wheel set 32 can be achieved by adjusting the tension of the tension spring or the gas pressure of the gas cylinder rod of the gas cylinder.

[0038] In some embodiments, the driving mechanism 2 comprises a power source 21 and two output shafts 23 connected with the power source 21, the two output shafts 23 are parallel and opposite in rotation direction, and the two output shafts 23 are connected with the upper polishing wheel set 31 and the lower polishing wheel set 32 respectively. Specifically, the power source 21 can evenly distribute power to the two output shafts 23 through a power distribution unit. The power source 21 evenly distributes power to the two output shafts 23, thereby driving the upper polishing wheel set 31 and the lower polishing wheel set 32 connected with the two output shafts 23 to rotate in opposite directions synchronously, which can throw the debris generated by polishing to the unpolished area, avoiding the subsequent increase of the cleaning process such as blowing.

[0039] In other embodiments, the base 1 is rotatably installed with two parallel main shafts 5, the two main shafts 5 are connected with the upper polishing wheel set 31 and the lower polishing wheel set 32 respectively, and the two output shafts 23 are connected with the two main shafts 5 through two transmission assemblies 24 respectively. Specifically, the power source 21 can evenly distribute power to the two output shafts 23 through a power distribution unit. The power output by the power source 21 is first evenly distributed to the two output shafts 23, and then each output shaft 23 transmits power to the corresponding main shaft 5 through an independent transmission assembly 24, thereby driving the upper polishing wheel set 31 and the lower polishing wheel set 32 to rotate in opposite directions synchronously, which can throw the debris generated by polishing to the unpolished area, avoiding the subsequent increase of the cleaning process such as blowing, and facilitating the placement of the power source 21 outside the dust cover 9, avoiding the occupation of the polishing area, to adapt to the polishing demand of smaller distance between two plates.

[0040] In this embodiment, the power source 21 is used to provide the power required for polishing, which can be a motor, a gas motor, etc.; the power distribution unit is used to evenly distribute the power provided by the power source 21 to the two output shafts 23, which can be a gear box 22; the transmission assembly 24 is used to drive the main shaft 5 to rotate synchronously with the corresponding output shaft 23, which can be a gear, a synchronous belt or a chain wheel, etc. Figures 2-3 As shown in the figure, the two main shafts 5 are parallel to the two output shafts 23, and the two output shafts 23 are drivingly connected with the two main shafts 5 through the two transmission assemblies 24 respectively; each transmission assembly 24 comprises two synchronous wheels and a tension wheel, the two synchronous wheels are installed on the main shaft 5 and the output shaft 23 respectively, and the tension wheel is rotatably installed on the base 1, and the two synchronous wheels and the tension wheel are drivingly connected through a belt.

[0041] Preferably, the upper polishing wheel set 31 and the lower polishing wheel set 32 are coaxially provided with universal joints 36, which are slidingly connected with the corresponding output shaft 23 or main shaft 5 through sliding keys 51. Specifically, the end of the rotating shaft 35 of the upper polishing wheel set 31 and the lower polishing wheel set 32 is coaxially connected with a universal joint 36, one end of the sliding key 51 is embedded and fixed in the end of the output shaft 23 or main shaft 5, and the other end of the sliding key 51 is slidingly connected with the corresponding universal joint 36. In this embodiment, the rotating shaft 35 of the upper polishing wheel set 31 and the lower polishing wheel set 32 is slidingly connected with the output shaft 23 or main shaft 5 through the universal joint 36 at the end and the sliding key 51 at the end of the output shaft 23 or main shaft 5, and the position of the upper sliding member 412 and the lower sliding member 413 is adjusted by the pressure adjusting assembly 42, so that the position of the polishing wheel 33 is accurately adjusted and continuously connected with the driving, which can adapt to different plate thicknesses and compensate for the wear of the polishing wheel 33, thereby improving the compatibility and application range of the equipment.

[0042] In some embodiments, the upper polishing wheel set 31 and the lower polishing wheel set 32 have the same structure, and each includes a polishing wheel 33, a bearing seat 34, and a rotating shaft 35. The bearing seat 34 is connected with the dynamic pressure and gravity balance mechanism 4, the rotating shaft 35 is rotatably installed in the bearing seat 34, the polishing wheel 33 is connected with one end of the rotating shaft 35, and the other end of the rotating shaft 35 is connected with the driving mechanism 2.

The bearing seat 34 in the middle of the rotating shaft 35 of the lower polishing wheel set 32 is fixedly connected with the lower sliding key 51, the other end of the rotating shaft 35 of the lower polishing wheel set 32 is coaxially connected with a universal joint 36, and the universal joint 36 is slidingly connected with the lower output shaft 23 or main shaft 5 of the driving mechanism 2 through the sliding key 51, so that the driving mechanism 2 provides power for the polishing wheel 33 of the lower polishing wheel set 32, and the lower polishing wheel set 32 can axially slide relative to the output shaft 23 or main shaft 5. By replacing the polishing wheel 33 adapted to the plate, the upper and lower surfaces of the plate can be polished synchronously, and the polishing efficiency is greatly improved.

[0043] As shown in Figure 1 and Figure 2As shown, the base 1 is used for fixing and carrying the driving mechanism 2, the polishing execution mechanism 3 and the dynamic pressure and gravity balance mechanism 4, and a dust cover 9 is fixed on the base 1 to cover the driving mechanism 2 except the power source 21, the polishing execution mechanism 3 except the polishing wheel 33 and the dynamic pressure and gravity balance mechanism 4, so that the internal complex mechanism can be long-term and reliable in the clean and safe environment.
