Description

Technical Field

[0001] The present application relates to the technical field of grinding equipment, and particularly relates to a surface grinding device for grid frame rods. Background Art

[0002] A grid frame is a space structure formed by connecting multiple rods in a certain form through nodes. During the construction process, multiple rods are required, and the rods are essential components for construction. Therefore, the quality of the rods is crucial for the quality of the entire grid frame. During the production process of the rods, they generally go through processes such as cutting, cone head assembly, welding, grinding, painting, and air drying. After welding, the grid frame rods need to be polished on the surface to remove rust by a shot blasting machine, so as to facilitate subsequent spraying on the surface of the grid frame rods.

[0003] For example, the Chinese patent document with the publication number CN219504526U discloses a pass-through type steel shot blasting cleaning machine, including a support mechanism. Inside the support mechanism, a shot blasting mechanism is fixedly connected, and a circulation mechanism is fixedly connected to the back of the support mechanism; the support mechanism includes a support frame and a cleaning chamber. The right side of the support frame is fixedly connected to one side of the cleaning chamber. Inside the support frame, steel is lapped. On both sides of the cleaning chamber, blocking tassels are fixedly connected; the shot blasting mechanism includes a shot storage bin and a shot blaster. The bottom of the shot storage bin is fixedly connected to the top of the shot blaster. A motor one is fixedly connected to the front of the cleaning chamber. By starting the motor one, the driving wheel rotates under the action of the rotation of the motor one shaft, and then the steel moves. At the same time, rubber particles are arranged on the surface of the driving wheel, making the friction between the driving wheel and the steel greater, and making it more convenient for the steel to move. Subsequently, the shot blaster is started, and under the action of the shot blaster, the steel shots in the shot storage bin are thrown out to remove the rust on the surface of the steel.

[0004] In the above related technology, through the operation of the shot blaster, the moving steel can be polished. However, the high-speed rotating impeller of the shot blasting machine throws abrasive materials such as steel shots onto the surface of the workpiece at a very high speed and a certain angle, generating impact and friction. This strong impact and friction will cause the rust to fall off and break from the surface of the steel, and then form powdery substances. Due to the violent collision between the steel shots and the surface of the workpiece, the rust powder and the surface of the workpiece will be charged. Due to the principle that like charges repel each other and opposite charges attract each other, a part of the powdery charged rust powder will be adsorbed onto the surface of the workpiece with the opposite charge, thus affecting the subsequent painting effect on the surface of the workpiece. Summary of the Invention

[0005] The present application provides a surface grinding device for grid frame rods, aiming to solve the problem of reducing the adhesion of rust powder to the surface of the workpiece in the related technology.

[0006] The surface grinding device for grid frame rods provided by the present application adopts the following technical solutions:

[0007] A surface grinding device for grid bars, comprising a main body of the grinding assembly and a cleaning chamber arranged on the grinding assembly. A plurality of conveying rollers for driving the grid bars to rotate and move are arranged in the cleaning chamber. A cleaning assembly for cleaning the rust powder adhering to the surface of the grid bars is arranged in the cleaning chamber. The cleaning assembly is arranged below the grid bars. The cleaning assembly includes a mounting frame arranged in the cleaning chamber, a first adjusting wheel, a second adjusting wheel and two rotating wheels rotatably connected to the mounting frame, and a cleaning belt. The cleaning belt is wound around the first adjusting wheel, the second adjusting wheel and the rotating wheels at the same time. The cleaning belt abuts against the surface of the grid bars, and a cleaning motor for driving the first adjusting wheel to rotate is arranged on the mounting frame.

[0008] By adopting the above technical solution, after the grinding assembly finishes grinding the grid bars, the grid bars enter the cleaning chamber. Under the action of the conveying rollers, the grid bars entering the cleaning chamber can move forward and rotate at the same time. Then, the cleaning motor drives the first adjusting wheel to rotate, and the first adjusting wheel drives the cleaning belt to rotate. Since the cleaning belt abuts against the surface of the grid bars, the rust powder adhering to the surface of the grid bars will be driven to fall off during the rotation of the cleaning belt. Since the grid bars can rotate, the rust powder adhering to the surface of the grid bars can be cleaned more thoroughly at this time, thereby making the spraying effect on the surface of the grid bars better in the later stage. Since the cleaning belt rotates, when the cleaning belt with rust powder rotates to the lower part, the rust powder will fall off from the cleaning belt under the action of gravity, and then when it contacts the surface of the grid bars subsequently, the rust powder on the cleaning belt adhering to the surface of the grid bars again can be reduced.

[0009] Optionally, a pressing assembly for pressing the grid bars on the cleaning belt is arranged on the cleaning chamber. The pressing assembly includes a first mounting rod rotatably connected to the inner wall of the cleaning chamber, a second mounting rod fixed on the first mounting rod, a first pressing wheel rotatably connected to the first mounting rod, and a pressing wheel rotatably connected to the second mounting rod. A second pressing motor for driving the first mounting rod to rotate is arranged on the cleaning chamber.

[0010] By adopting the above technical solution, when the grid bar has not moved below the pressing assembly, the axes of the first pressing wheel and the second pressing wheel are on the same horizontal plane. Then, when the grid bar moves below the first pressing wheel and the second pressing wheel, the pressing motor drives the first mounting rod and the second mounting rod to rotate, so that the second pressing wheel on the second mounting rod moves towards the grid bar, and the first pressing wheel moves away from the grid bar. The grid bar is pressed against the cleaning belt by the second pressing wheel. Then, after the grid bar below the second pressing wheel is cleaned, there is no grid bar below the second pressing wheel, and the grid bar to be polished will move below the first pressing wheel. At this time, the first mounting rod drives the second mounting rod to move in the reverse direction, the first pressing wheel moves towards the grid bar, and the second pressing wheel moves away from the grid bar, so as to reduce the blockage caused by the first pressing wheel or the second pressing wheel to the movement of the grid bar when pressing the grid bar.

[0011] Optionally, a detection component for detecting the position of the grid bar is arranged in the cleaning chamber; the detection component includes a first distance sensor and a second distance sensor arranged in the cleaning chamber and a controller arranged in the cleaning chamber, and the controller is used to be connected to the first distance sensor, the second distance sensor and the pressing motor.

[0012] By adopting the above technical solution, when the first pressing wheel abuts against the grid bar, the first sensor works, and when the second pressing wheel abuts against the grid bar, the second sensor works. In the initial state, the second pressing wheel abuts against the surface of the grid bar. Then, after the previous grid bar is cleaned, the second pressing wheel no longer abuts against the surface of the grid bar. At this time, the second sensor detects a change in the distance, causing the pressing motor to work. The pressing motor drives the first mounting rod to rotate in the reverse direction, so that the first pressing wheel abuts against the grid bar conveyed later, and thus the first pressing wheel and the second pressing wheel can work alternately automatically.

[0013] Optionally, a support component for supporting the cleaning belt below the grid bar is arranged on the mounting frame; the support component includes two support rollers rotatably connected to the mounting frame, and the two support rollers are arranged below the cleaning belt and are spaced apart.

[0014] By adopting the above technical solution, under the action of the two support rollers, the cleaning belt below the grid bar is in an arc structure, and then the contact area between the cleaning belt and the grid bar can be increased, and the cleaning efficiency is faster.

[0015] Optionally, a jitter component for jittering the cleaning belt rotated to the lower side and a clamping component for clamping both ends of the jittered cleaning belt are provided on the mounting bracket. The jitter component includes a moving rod slidably connected to the mounting bracket and a jitter roller rotatably connected to the moving rod. The jitter roller abuts against the upper surface of the cleaning belt rotated to the lower side. A driving component for driving the moving rod to slide in the vertical direction is provided on the mounting bracket.

[0016] By adopting the above technical solution, when cleaning the rust powder on the cleaning belt rotated to the lower side, first, the clamping component clamps both ends of the cleaning belt to be cleaned. Then, the driving component drives the moving rod and the jitter roller to move downward. At this time, the clamped cleaning belt is stretched. Then, when the moving rod is released, the jitter roller is reset under the action of the elasticity of the cleaning belt itself, so as to make the cleaning belt jitter, which is convenient for cleaning the rust powder electrostatically attached to the cleaning belt. Then, when the cleaning belt rotates to the upper side to clean the grid frame rod, the rust powder on the cleaning belt can be reduced from adhering to the surface of the cleaned grid frame rod again.

[0017] Optionally, the driving component includes a driving cam rotatably connected to the mounting bracket, a driving rod fixed to the moving rod, a driving motor fixed to the mounting bracket, and a driving spring fixed to the mounting bracket. One end of the driving spring is fixed to the moving rod, and the side surface of the driving cam abuts against the driving rod.

[0018] By adopting the above technical solution, the driving motor rotates to drive the driving cam to rotate. Then, the driving cam pushes the driving rod to move downward. While the driving rod moves, it drives the jitter roller to move downward. At this time, the clamped cleaning belt is stretched. After the driving cam and the driving rod are separated, under the action of the driving spring, the jitter roller is reset, and then the clamped cleaning belt is also reset, thus achieving the purpose of facilitating the movement of the jitter roller.

[0019] Optionally, the clamping component includes a first clamping plate fixed to the mounting bracket, a second clamping plate slidably connected to the mounting bracket, and a clamping cylinder fixed to the mounting bracket. The piston rod of the clamping cylinder is fixed to the second clamping plate and is used to drive the second clamping plate to move away from or close to the first clamping plate. The cleaning belt rotated to the lower side is located between the first clamping plate and the second clamping plate.

[0020] By adopting the above technical solution, before the jitter roller moves downward, the second clamping plate moves toward the first clamping plate, and the cleaning belt is clamped by the first clamping plate and the second clamping plate. Finally, when the cleaning belt jitters, the jitter of the cleaning belt at other positions can be reduced.

[0021] Optionally, an adjusting component is provided on the mounting frame. The adjusting component is used to adjust the positions of the first adjusting wheel and the second adjusting wheel. The adjusting component includes a first adjusting block and a second adjusting block slidably connected to the mounting frame, and a bidirectional screw rotatably connected to the mounting frame. The bidirectional screw passes through the first adjusting block and the second adjusting block and is threadedly connected to the first adjusting block and the second adjusting block. The first adjusting wheel is rotatably connected to the first adjusting block, and the second adjusting wheel is rotatably connected to the second adjusting block.

[0022] By adopting the above technical solution, when it is necessary to shake the cleaning belt, the first adjusting wheel and the second adjusting wheel move in opposite directions, and then the entire cleaning belt can still be in an operating state. Thus, on the one hand, the cleaning belt rotating to the lower part can be shaken, and on the other hand, the cleaning belt above can clean the rust powder adhering to the grid frame rod, thereby improving the grinding and cleaning efficiency of the entire grid frame rod.

[0023] Optionally, two partition plates are provided on the mounting frame. The clamping component and the shaking component are arranged between the two partition plates, and a partition chamber is formed between the two partition plates and the mounting frame.

[0024] By adopting the above technical solution, after shaking the cleaning belt, the rust powder adhering to the cleaning belt will fall into the partition chamber, and then the floating rust powder removed can be reduced from floating into the cleaning chamber.

[0025] Optionally, an inclined surface for abutting against the side surface of the driving cam is provided on the driving rod.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. During the rotation of the cleaning belt, the rust powder adhering to the surface of the grid frame rod will be driven to break away. Since the grid frame rod can rotate, the rust powder adhering to the surface of the grid frame rod can be cleaned more thoroughly at this time, thereby making the spraying effect on the surface of the grid frame rod better in the later stage.

[0028] 2. The supporting roller makes the cleaning belt below the grid frame rod in an arc structure, and then the contact area between the cleaning belt and the grid frame rod can be increased, and the cleaning efficiency can be faster. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0036] The following is a further detailed description of the present application in conjunction with Figures 1-6 to further illustrate the present application in detail.

[0037] The embodiment of the present application discloses a surface grinding device for grid frame rods. Refer to Figure 1 and Figure 2 , a surface grinding device for grid frame rods includes a grinding machine body 01 and a cleaning chamber 02 provided on the grinding machine body 01. The grinding machine body 01 is set as a shot blasting machine. After welding, the grid frame rod is moved into the shot blasting machine, and the surface of the welded grid frame rod is ground by the shot blasting machine to remove the rust on the surface of the grid frame rod. Since the shot blasting machine belongs to the prior art, in this embodiment, the specific working principle of the shot blasting machine will not be described in detail. A cleaning component 1, a pressing component 2 and a detection component 3 are arranged in the cleaning chamber 02. The cleaning component 1 is used to further clean the rust powder attached to the surface of the grid frame rod. The pressing component 2 is used to make the grid frame rod better contact with the pressing component 2. The detection component 3 is used to detect the position of the grid frame rod, and then reduce the blocking of the moving grid frame rod by the pressing component 2; at the same time, a plurality of conveying rollers for driving the grid frame rod to rotate and move are arranged in the cleaning chamber 02.

[0038] Refer to Figures 2-4, the cleaning component 1 includes a mounting bracket 11 fixedly installed in the cleaning chamber 02, a first adjusting wheel 12, a second adjusting wheel 13 and two rotating wheels 14 rotatably connected to the mounting bracket 11, and a cleaning belt 15. In this embodiment, the cleaning belt 15 is made of conductive silicone rubber material. The first adjusting wheel 12 and the second adjusting wheel 13 are arranged on the same horizontal plane, and the two rotating wheels 14 are arranged on the same horizontal plane. The cleaning belt 15 is wound around the first adjusting wheel 12, the second adjusting wheel 13 and the two rotating wheels 14 at the same time. The two rotating wheels 14 are arranged above the first adjusting wheel 12 and the second adjusting wheel 13. The cleaning belt 15 is arranged below the grid bar. At the same time, the pressing component 2 presses the grid bar to be cleaned against the cleaning belt 15 below. And a cleaning motor for driving the first adjusting wheel 12 to rotate is arranged on the mounting bracket 11, and the output shaft of the cleaning motor is fixed on the first adjusting wheel 12; under the action of the two rotating wheels 14 and the first adjusting wheel 12 and the second adjusting wheel 13, the annular cleaning belt 15 forms an upper cleaning belt 15 and a lower cleaning belt 15. The upper cleaning belt 15 is used to abut against the grid bar, and the rotating direction of the cleaning belt 15 is perpendicular to the moving direction of the grid bar.

[0039] Refer to Figures 2-4 , when the pressing component 2 presses the grid bar against the upper surface of the cleaning belt 15, the cleaning motor rotates to drive the first adjusting wheel 12 to rotate. The first adjusting wheel 12 drives the cleaning belt 15 to rotate. When the cleaning belt 15 rotates, it drives the rotating wheels 14 and the second adjusting wheel 13 to rotate. When the cleaning belt 15 rotates, the cleaning belt 15 grinds the surface of the grid bar, and then cleans the rust powder adhering to the surface of the grid bar, thereby reducing the rust powder on the surface of the grid bar, and then making the subsequent spraying effect better. In addition, since the cleaning belt 15 is made of conductive silicone rubber material, the generation of static electricity can be reduced, and then the rust powder on the grid bar can be cleaned better.

[0040] Refer to Figures 2-4 , a supporting component 4 is arranged on the mounting bracket 11. The supporting component 4 is used to support the cleaning belt 15 below the grid bar, and then increase the contact area between the grid bar and the cleaning belt 15, thereby improving the cleaning efficiency of the surface of the grid bar. The supporting component 4 includes two supporting rollers 41 rotatably connected to the mounting bracket 11. The axes of the two supporting rollers 41 are in the same plane. The supporting rollers 41 are arranged on both sides of the grid bar, and the cleaning belt 15 below the grid bar is in an arc structure, and then the contact area between the grid bar and the cleaning belt 15 can be increased.

[0041] Refer to Figure 2 and Figure 3, the pressing assembly 2 includes a first mounting rod 21, a second mounting rod 22, a first pressing wheel 23 and a second pressing wheel 24. The first mounting rod 21 is rotatably connected to the inner wall of the cleaning chamber 02. The second mounting rod 22 is fixed to the first mounting rod 21. The first pressing wheel 23 is rotatably connected to the first mounting rod 21. The second pressing wheel 24 is rotatably connected to the second pressing wheel 24. And the first mounting rod 21 and the second mounting rod 22 are arranged at an angle. The angle between the first mounting rod 21 and the second mounting rod 22 is greater than 90 degrees and less than 180 degrees. In the initial state, the first pressing wheel 23 and the second pressing wheel 24 are at the same height and are arranged above the grid bars. To facilitate the rotation of the first mounting rod 21 and the second mounting rod 22, a pressing motor is fixedly installed on the inner wall of the cleaning chamber 02. The output shaft of the pressing motor is fixed to the first mounting rod 21. By rotating the pressing motor forward or backward, the heights of the first pressing wheel 23 and the second pressing wheel 24 can be adjusted.

[0042] When the grid bars move below the first pressing wheel 23 and the second pressing wheel 24, the second pressing wheel 24 first abuts against the surface of the moving grid bars, and then makes the grid bars abut against the cleaning belt 15. After the grid bars abutted by the second pressing wheel 24 are cleaned, there are no grid bars below the second pressing wheel 24, and at the same time, the grid bars that have not been cleaned behind move below the first pressing wheel 23. At this time, by rotating the pressing motor, the pressing motor drives the first mounting rod 21 and the second mounting rod 22 to rotate, so that the second pressing wheel 24 rotates upward and the first pressing wheel 23 rotates downward. During the rotation process, the first pressing wheel 23 abuts against the surface of the grid bars that have not been cleaned, thereby pressing the grid bars that have not been cleaned. The pressed grid bars move below the second pressing wheel 24 and do not abut against the second pressing wheel 24 at this time. When the first pressing wheel 23 cannot abut against the grid bars, the pressing motor rotates, and then makes the second pressing wheel 24 abut against the surface of the grid bars. Thus, when pressing the grid bars, the first pressing wheel 23 and the second pressing wheel 24 are alternately arranged, and then it is convenient for the grid bars to move below the first pressing wheel 23 or the second pressing wheel 24.

[0043] Refer to Figures 2-4 , the detection assembly 3 includes a first distance sensor 31 and a second distance sensor 32 arranged on the mounting frame 11 and a controller arranged on the mounting frame 11. The first distance sensor 31 and the second distance sensor 32 are arranged below the grid bars and are used to detect the positions of the grid bars. The first distance sensor 31 is used to detect the position of the first pressing wheel 23, and the second distance sensor 32 is used to detect the position of the second pressing wheel 24. Then the first distance sensor 31 and the second distance sensor 32 are connected to the controller, and at the same time, the pressing motor is also connected to the controller.

[0044] In the initial state, the first distance sensor 31 is not working. Then the second distance sensor 32 works. Then the grid frame rod moves above the first distance sensor 31 and the second distance sensor 32, and the second pressing wheel 24 abuts against the surface of the grid frame rod. When there is no grid frame rod above the second distance sensor 32, the second distance sensor 32 detects an increase in distance. At this time, a signal is sent to the pressing motor, and then the pressing motor drives the first mounting rod 21 and the second mounting rod 22 to rotate in opposite directions. Finally, the first pressing wheel 23 abuts against the grid frame rod conveyed from the rear. At this time, the second distance sensor 32 stops working. In this embodiment, through the settings of the first distance sensor 31 and the second distance sensor 32, the first pressing wheel 23 and the second pressing wheel 24 can work alternately, and then it is convenient for the grid frame rod to move below the first pressing wheel 23 and the second pressing wheel 24.

[0045] Referring to Figures 2-5 , a shaking assembly 5 is provided on the mounting frame 11. The shaking assembly 5 is used to shake the cleaning belt 15 that rotates to the lower part, and then clean the rust powder on the cleaning belt 15. At the same time, a clamping assembly 6 is provided on the mounting frame 11. The clamping assembly 6 is used to clamp both ends of the cleaning belt 15 that needs to be shaken, and then reduce the influence on the cleaning belt 15 at other positions. In this embodiment, two sets of clamping assemblies 6 are provided, and the two sets of clamping assemblies 6 are arranged on opposite sides of the shaking assembly 5.

[0046] Referring to Figures 2-5 , the shaking assembly 5 includes a moving rod 51 slidably connected to the mounting frame 11 and a shaking roller 52 rotatably connected to the moving rod 51. The shaking roller 52 is arranged above the lower cleaning belt 15 and abuts against the upper surface of the lower cleaning belt 15. A driving assembly 7 is provided on the mounting frame 11. The driving assembly 7 is used to drive the moving rod 51 to slide on the mounting frame 11.

[0047] Referring to Figures 2-5, the driving assembly 7 includes a driving cam 71 rotatably connected to the mounting frame 11, a driving motor fixed to the mounting frame 11, a driving rod 73 fixed to the moving rod 51, and a driving spring 74 fixed to the moving rod 51. The driving rod 73 is perpendicular to the moving rod 51, and the side surface of the driving cam 71 abuts against the driving rod 73. One end of the driving spring 74 is fixed to the mounting frame 11. In the initial state, under the action of the driving spring 74, the position of the shaking roller 52 is supported, so as to facilitate the lower cleaning belt 15 to maintain a horizontal state. Then, when the shaking roller 52 moves downward, first, the cleaning belt 15 is fixed in position by the clamping assembly 6. By rotating the driving cam 71, the rotation of the driving cam 71 drives the driving rod 73 to move, and the driving rod 73 drives the moving rod 51 and the shaking roller 52 to move downward. At this time, the driving spring 74 is in a compressed state, and the clamped cleaning belt 15 is gradually stretched. Then, when the side surface of the convex part of the driving cam 71 no longer abuts against the driving rod 73, the driving spring 74 drives the shaking roller 52 to reset, and at the same time, the stretched cleaning belt 15 also returns to its initial length, so as to achieve the purpose of facilitating the cleaning of rust powder on the cleaning belt 15 during the shaking process. In addition, an inclined surface for abutting against the side surface of the driving cam 71 is provided on the driving rod 73. Since the inclined surface is provided on the driving rod 73, the contact area between the driving rod 73 and the driving cam 71 can be increased, so that the driving cam 71 can push the driving rod 73 to move more stably.

[0048] Refer to Figures 2-6 , the clamping assembly 6 includes a first clamping plate 61 fixed to the mounting frame 11, a second clamping plate 62 slidably connected to the mounting frame 11, and a clamping cylinder 63 fixed to the mounting frame 11. The output shaft of the clamping cylinder 63 is fixedly connected to the second clamping plate 62. The first clamping plate 61 is arranged above the lower cleaning belt 15 and abuts against the upper surface of the lower cleaning belt 15. When it is necessary to shake the rust powder on the cleaning belt 15, the clamping cylinder 63 drives the second clamping plate 62 to move towards the first clamping plate 61, and then the cleaning belt 15 is clamped and fixed, so as to facilitate the shaking roller 52 to pull the cleaning belt 15 between the two clamping assemblies 6.

[0049] Refer to Figures 2-5 , two partition plates 03 are arranged on the mounting frame 11. The two partition plates 03 are arranged in parallel at intervals, and a partition chamber 04 is formed between the two partition plates 03 and the mounting frame 11. The two clamping assemblies 6 and the shaking assembly 5 are both arranged in the partition chamber 04. Then, when the shaking assembly 5 works, the rust powder separated from the cleaning belt 15 can be reduced from floating out.

[0050] Refer to Figures 2-6, an adjusting assembly 8 for adjusting the positions of the first adjusting wheel 12 and the second adjusting wheel 13 is provided on the mounting frame 11. The adjusting assembly 8 includes a first adjusting block 81 and a second adjusting block 82 slidably connected to the mounting frame 11 and a bidirectional screw 83 rotatably connected to the mounting frame 11. The first adjusting wheel 12 is rotatably connected to the first adjusting block 81, and the second adjusting wheel 13 is rotatably connected to the second adjusting block 82. Both the first adjusting block 81 and the second adjusting block 82 are sleeved on the bidirectional screw 83 and are threadedly connected to the bidirectional screw 83. At the same time, a buffer motor is fixedly installed on the mounting frame 11, and the output shaft of the buffer motor is fixedly connected to the bidirectional screw 83. By rotating the buffer motor, the bidirectional screw 83 is driven to rotate. When the bidirectional screw 83 rotates, the first adjusting block 81 and the second adjusting block 82 will be driven to move in opposite directions.

[0051] When cleaning the cleaning belt 15 below the shaking grid bar, the clamping assembly 6 needs to fix the cleaning belt 15 to be shaken. The cleaning motor stops working. Then, the first adjusting block 81 on the left side of the shaking assembly 5 drives the first adjusting wheel 12 to move to the left, and the second adjusting block 82 drives the second adjusting wheel 13 to move to the right. At this time, the cleaning belt 15 pressed on the right side is released, and at the same time, the loosened cleaning belt 15 on the left side is tightened. Therefore, when shaking the cleaning belt 15, the first adjusting block 81 and the second adjusting block 82 will drive the cleaning belt 15 that is not clamped to move, so as to ensure that the cleaning belts 15 at other positions are not affected and can continue to move. After the cleaning is completed, the first adjusting block 81 and the second adjusting block 82 are reset, and then the cleaning motor works to continue driving the cleaning belt 15 to rotate.

[0052] The implementation principle of a grid bar surface grinding device according to an embodiment of the present application is as follows: After the grid bar is polished by a shot blasting machine, it enters the cleaning chamber 02. At this time, the grid bar is pressed against the cleaning belt 15 by the pressing assembly 2. The cleaning motor drives the first adjusting wheel 12 to rotate, and then the cleaning belt 15 is driven to rotate in a direction perpendicular to the movement direction of the grid bar. During the rotation process, the rust powder attached to the surface of the grid bar is cleaned. The cleaned rust powder will adhere to the cleaning belt 15. When the cleaning belt 15 with rust powder rotates to the lower part, the shaking assembly 5 works to clean the rust powder that is difficult to clean on the cleaning belt 15. On the one hand, it can reduce the adhesion of rust powder to the cleaning belt 15, and on the other hand, it is convenient to clean the rust powder on the surface of the grid bar.

[0053] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
