At this time, the worn side wall of the grinding wheel abuts against the rolling roller, and the grinding wheel is driven to rotate through the rotating member, which facilitates the grinding of the rolling roller surface, reduces the adverse effects on the service life of the grinding wheel, and improves resource utilization.

[0008] Optionally, the sliding member includes a sliding shaft at one end passing through the grinding wheel and fixedly connected to the grinding wheel, a sliding seat is inserted and slidably connected to the movable arm, the sliding shaft passes through the sliding seat and the movable arm and is rotatably connected to the sliding seat, the second contact is installed on the side of the sliding seat away from the rolling roller and close to the rolling roller, a sliding hole adapted for the sliding seat is provided on the movable arm, a lead screw adapted for the moving trajectory of the sliding seat is passed through and threadedly connected at the lower end of the sliding seat, the lead screw is rotatably connected to the movable arm, and a driving member for driving the lead screw to rotate is provided on the movable arm.

At this time, the sliding seat threadedly connected to the lead screw drives the grinding wheel to move along the sliding hole toward the roller through the sliding shaft until the worn side wall of the grinding wheel abuts against the roller. At this time, the control host receives the electrical signal sent by the second contact, which reduces the adverse effects on the service life of the grinding wheel and improves resource utilization.

[0010] Optionally, the moving assembly includes a moving rod corresponding to the moving arm one by one and fixedly connected to the end of the moving arm away from the roller, the end of the moving rod away from the roller passes through the side wall of the mounting frame and is slidably connected to the side wall of the mounting frame, a first spring is provided between the moving rod and the side wall of the mounting frame, a locking piece is provided on the moving rod, a rack is provided on the moving rod, one end of the rack can abut against the end of the moving arm, and a moving piece is provided on the mounting frame to drive the rack to drive the moving arm to move.

[0011] By adopting the above technical solution, the moving part drives the rack to move toward the direction close to the rolling roller and pushes the moving arm to drive the moving rod to move toward the direction close to the rolling roller. The first spring is deformed until the detection roller abuts against the side wall of the rolling roller. At this time, the locking part makes the moving rod and the mounting frame relatively fixed, thereby facilitating the fixing of the moving arm, and drives the grinding wheel to continue to move through the sliding part until it abuts against the side wall of the rolling roller, thereby reducing the adverse effects on the service life of the grinding wheel and improving resource utilization.

[0013] By adopting the above technical solution, when the movable arm moves in the direction close to the rolling roller, the locking block completely enters the movable rod under the squeezing of the side wall of the mounting frame. At this time, the second spring is compressed. When the movable arm moves until the locking block is separated from the side wall of the mounting frame, the second spring restores its deformation and pushes the locking block to move in the direction away from the movable rod, thereby cooperating with the first spring and fixing the movable rod on the side wall of the mounting frame. When unlocking, the driving rack drives the unlocking plate to move in the direction close to the locking block and squeezes the locking block until the locking block completely enters the movable rod. At this time, the first spring restores its shape and drives the movable rod to drive the movable arm to reset, which is convenient for replacing grinding wheels of different finenesses to grind the rolling roller and improves work efficiency.

[0014] Optionally, a cavity is defined inside the movable arm, and a mounting hole adapted for the cavity is defined at one end of the movable arm close to the movable rod, a blocking block for blocking the mounting hole is slidably connected to the side wall of the movable arm, the driving member comprises a first bevel gear sleeved on the end of the lead screw, a second bevel gear is meshed with one side of the first bevel gear, a first gear is provided on one side of the second bevel gear, an end of the rack close to the rolling roller can pass through the mounting hole and mesh with the first gear, a control member for controlling the rotation of the lead screw is provided between the first gear and the second bevel gear, and a blocking member for driving the blocking block to move is provided on the movable arm.

[0015] By adopting the above technical solution, when the rack pushes the movable arm to move in the direction close to the rolling roller, the end of the rack abuts against the blocking block. When the movable arm moves to the point where the detection roller abuts against the side wall of the rolling roller, the blocking block is driven to open the mounting hole through the blocking piece. At this time, the rack continues to be driven to move in the direction close to the rolling roller until the end of the rack enters the cavity and drives the first gear to rotate. At this time, the first gear drives the second bevel gear to rotate through the control piece and drives the first bevel gear and the lead screw to rotate, thereby driving the grinding wheel to continue to move in the direction close to the rolling roller until it abuts against the side wall of the rolling roller, thereby reducing the adverse effects on the service life of the grinding wheel and improving resource utilization.

[0016] Optionally, the control member includes a ratchet that is coaxial with and fixedly connected to the second bevel gear, the ratchet is inserted into the axis of the first gear, and a pawl that meshes with the ratchet is hinged on the inner side wall of the first gear. When the rack moves toward the direction close to the rolling roller, the first gear drives the second bevel gear to rotate through the ratchet and the pawl.

[0017] By adopting the above technical solution, when the rack moves toward the direction approaching the rolling roller, the ratchet and the pawl make the first gear and the second bevel gear relatively fixed, which is convenient for driving the screw to rotate; when the rack moves away from the rolling roller and drives the movable arm to reset, the ratchet and the pawl make the first gear and the second bevel gear rotate relative to each other, reducing the adverse effect of the rotation of the first gear on the relative position of the grinding wheel on the movable arm.

[0018] Optionally, the blocking member includes a blocking rod with one end inserted into the moving rod, a third spring is installed between the blocking rod and the moving rod, the side of the blocking rod close to the locking block is arranged as an inclined surface inclined toward the side away from the rolling roller and away from the locking block and abuts against the locking block, the other end of the blocking rod is inserted into the moving arm and is arranged as an inclined surface inclined downward toward the side close to the rolling roller, when the blocking block blocks the mounting hole, the inclined surface of one end of the blocking rod close to the rolling roller abuts against the lower side of the blocking block.

[0019] By adopting the above technical solution, when the locking block is fully inserted into the moving rod, the end of the blocking rod close to the blocking block is located at the lower side of the blocking block, the blocking block blocks the mounting hole, and the third spring is stretched. When the locking block pops out and fixes the moving rod, the third spring recovers its deformation and pulls the blocking rod to move in the direction away from the roller until it is separated from the blocking block. At this time, the blocking block slides downward and opens the mounting hole, which is convenient for driving the rack into the cavity and driving the lead screw to rotate. When the grinding wheel corresponding to this moving arm completes grinding, the driving rack moves in the direction away from the roller until the unlocking plate squeezes the locking block and completely enters the moving rod. At this time, the end of the locking block squeezes the inclined surface of the blocking rod away from one end of the roller and pushes the blocking rod to move in the direction close to the blocking block, until the inclined surface of the blocking rod close to one end of the roller pushes the blocking block to move upward and block the mounting hole again, which is convenient for driving the moving arm to move again, thereby improving work efficiency.

[0023] By adopting the above technical solution, the second motor drives the rotating roller to rotate, thereby driving the grinding wheel to rotate along with the rotating roller through the elastic belt and the sliding shaft, and the elastic belt produces elastic deformation when the grinding wheel moves, so that the rotating roller and the grinding wheel can always be connected to each other, which is convenient for driving the grinding wheel to rotate and improving work efficiency.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: The moving component drives the moving arm to drive the grinding wheel and the detection roller to move in the direction close to the roller until the side wall of the detection roller abuts against the side wall of the roller, and the control host receives the electrical signal of the first contact point and stops driving the moving arm to move, and drives the grinding wheel to move in the direction close to the roller through the sliding member until the control host receives the electrical signal of the second contact point. At this time, the worn side wall of the grinding wheel abuts against the roller, and the grinding wheel is driven to rotate through the rotating member, which is convenient for grinding the surface of the roller, reducing the adverse effect on the service life of the grinding wheel and improving resource utilization; When the moving arm moves in the direction close to the rolling roller, the locking block completely enters the moving rod under the pressure of the side wall of the mounting frame, and the second spring is compressed at this time. When the moving arm moves until the locking block is separated from the side wall of the mounting frame, the second spring recovers its deformation and pushes the locking block to move in the direction away from the moving rod, thereby cooperating with the first spring and fixing the moving rod on the side wall of the mounting frame. When unlocking, the driving rack drives the unlocking plate to move in the direction close to the locking block and squeezes the locking block until the locking block completely enters the moving rod. At this time, the first spring recovers its shape and drives the moving rod to drive the moving arm to reset, which is convenient for replacing grinding wheels of different finenesses to grind the rolling roller and improves work efficiency. When the rack pushes the movable arm to move in the direction close to the rolling roller, the end of the rack abuts against the blocking block. When the movable arm moves to the point where the detection roller abuts against the side wall of the rolling roller, the blocking block is driven to open the mounting hole through the blocking piece. At this time, the rack continues to be driven to move in the direction close to the rolling roller until the end of the rack enters the cavity and drives the first gear to rotate. At this time, the first gear drives the second bevel gear to rotate through the control piece and drives the first bevel gear and the lead screw to rotate, thereby driving the grinding wheel to continue to move in the direction close to the rolling roller until it abuts against the side wall of the rolling roller, thereby reducing the adverse effects on the service life of the grinding wheel and improving resource utilization.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses a grinding machine. Figure 1 and Figure 2 A grinder includes a grinder body 1 and a mounting frame 2 slidably connected to the upper side of the grinder body 1 along the length direction of the grinder body 1. A roller is mounted on the grinder body 1 and driven to rotate by the grinder body 1. The mounting frame 2 opens toward the roller, and is provided with a plurality of vertical grinding wheels 21 arranged in sequence along the length direction of the roller and having different finenesses. In the embodiment of the present application, three grinding wheels are provided.

[0033] Reference Figure 2 and Figure 3The mounting frame 2 is provided with a horizontal movable arm 3 corresponding to the grinding wheel 21 and facing the roller. The grinding wheel 21 is located on the same side of the corresponding movable arm 3 and is slidably and rotatably connected with the corresponding movable arm 3. The movable arm 3 is provided with a sliding member 31 for driving the grinding wheel 21 to move in a direction close to the roller, and the mounting frame 2 is provided with a rotating member 22 located on the upper side of the movable arm 3 and driving the grinding wheel 21 to rotate. The end of the movable arm 3 close to the roller is rotatably connected with a detection roller 32, and the detection roller 32 is installed with a first contact (not shown in the figure), and the mounting frame 2 is provided with a movable assembly 4 for driving the movable arm 3 to move in a direction close to the roller. The grinding wheel 21 is provided with a second contact (not shown in the figure) that does not contact the roller. The first contact and the second contact are both wirelessly connected to a control host (not shown in the figure), and the movable assembly 4 and the sliding member 31 are both wirelessly connected to the control host.

[0034] The moving component 4 drives the moving arm 3 to drive the grinding wheel 21 and the detection roller 32 to move toward the rolling roller until the side wall of the detection roller 32 abuts against the side wall of the rolling roller. The control host receives the electrical signal of the first contact and stops driving the moving arm 3 to move, and drives the grinding wheel 21 to move toward the rolling roller through the sliding member 31 until the control host receives the electrical signal of the second contact. At this time, the side wall of the worn grinding wheel 21 abuts against the rolling roller, and the grinding wheel 21 is driven to rotate through the rotating member 22, so as to grind the surface of the rolling roller.

[0035] Reference Figure 3 The sliding member 31 includes a horizontal sliding shaft 311, one end of which passes through the corresponding grinding wheel 21 axis and is fixedly connected to the grinding wheel 21. The other end of the sliding shaft 311 passes through the corresponding moving arm 3 and moves along the length direction of the moving arm 3 toward the roller. The moving arm 3 is provided with a sliding hole 33 adapted to the movement trajectory of the sliding shaft 311, and the sliding hole 33 is provided with a sliding seat 312 inserted into the sliding hole 33. The sliding shaft 311 passes through the upper end of the sliding seat 312 and is rotatably connected to the sliding seat 312. The second contact is installed on the side of the sliding seat 312 away from the roller and close to the sliding shaft 311. The lower end of the sliding seat 312 is penetrated and threadedly connected with a lead screw 313 facing the roller and rotatably connected to the side wall of the moving arm 3, and the moving arm 3 is provided with a driving member 34 for driving the lead screw 313 to rotate.

[0036] Reference Figure 2The rotating member 22 includes a rotating roller 221 located at the upper end of the interior of the mounting frame 2 and arranged along the length direction of the grinding machine body 1. The rotating roller 221 is horizontal and rotatably connected to the side wall of the mounting frame 2. An elastic band 222 that corresponds to the grinding wheel 21 one by one and can undergo elastic deformation is sleeved on the rotating roller 221. The ends of the elastic bands 222 away from the rotating roller 221 are sleeved on the ends of the corresponding sliding shafts 311 away from the grinding wheel 21. A second motor 223 is fixedly connected to one side of the exterior of the mounting frame 2. The output shaft of the second motor 223 passes through the side wall of the mounting frame 2 and is fixedly connected to the end of the rotating roller 221.

[0037] The lead screw 313 is driven to rotate by the driving member 34. At this time, the sliding seat 312 threadedly connected to the lead screw 313 drives the grinding wheel 21 to move along the sliding hole 33 toward the roller through the sliding shaft 311, until the worn side wall of the grinding wheel 21 abuts against the roller. At this time, the control host receives the electrical signal sent by the second contact, and the second motor 223 drives the rotating roller 221 to rotate, thereby driving the grinding wheel 21 to rotate with the rotating roller 221 through the elastic belt 222 and the sliding shaft 311, and the elastic belt 222 generates elastic deformation when the grinding wheel 21 moves, so that the rotating roller 221 and the grinding wheel 21 can always be connected to each other, which is convenient for driving the grinding wheel 21 to rotate.

[0038] Reference Figure 2 and Figure 3 The moving assembly 4 includes a horizontal moving rod 41 fixedly connected to the end of the moving arm 3 away from the roller and facing the roller. The end of the moving rod 41 away from the moving arm 3 passes through the side wall of the mounting frame 2 and is slidably connected to the side wall of the mounting frame 2. The end of the moving rod 41 passing through the side wall of the mounting frame 2 is sleeved with a first spring 42. One end of the first spring 42 is fixedly connected to the outer side wall of the mounting frame 2, and the other end is fixedly connected to the end of the moving rod 41. Figure 3 , Figure 4 and Figure 5 A rack 43 parallel to the moving rod 41 is provided on the upper side of the end of the moving rod 41 close to the roller, and the end of the rack 43 close to the roller can abut against the end of the moving arm 3 away from the roller, and a moving member 44 for driving the rack 43 to move is provided in the mounting frame 2. A locking member 45 is provided on the moving rod 41, and when the moving arm 3 moves to the point where the detection roller 32 abuts against the side wall of the roller, the locking member 45 fixes the relative position of the moving rod 41 on the mounting frame 2.

[0039] Reference Figure 3 and Figure 5The moving member 44 includes a vertical second gear 441 located on the upper side of the rack 43, and the rack 43 can mesh with the second gear 441, and a first motor 442 is installed on one side of the second gear 441. A hydraulic cylinder 443 is provided horizontally and facing the first motor 442 on the side of the first motor 442 away from the second gear 441, and a telescopic rod of the hydraulic cylinder 443 is fixedly connected to the first motor 442, and an end of the hydraulic cylinder 443 away from the telescopic rod passes through the side wall of the mounting frame 2 and is fixedly connected to the mounting frame 2.

[0040] Reference Figure 3 , Figure 4 and Figure 5 The locking member 45 includes two locking blocks 451 located in the mounting frame 2 and symmetrically arranged on both sides of the moving rod 41. The moving rod 41 is provided with a connecting hole 411 adapted to the locking blocks 451. The sides of the locking blocks 451 close to each other are inserted into the connecting hole 411 and slidably connected to the moving rod 41. The locking blocks 451 can be completely located in the connecting hole 411. The area of ​​the end of the locking blocks 451 close to each other is larger than the cross-sectional area of ​​the connecting hole 411, and the end of the locking blocks 451 close to each other is fixedly connected with a second spring 452 connecting the two. When the detection roller 32 abuts against the side wall of the roller, the end of the locking blocks 451 away from each other is located outside the moving rod 41, and the side of the locking blocks 451 away from the roller abuts against the side of the mounting frame 2 away from the roller. At this time, the first spring 42 is compressed.

[0041] Two vertically and symmetrically arranged unlocking plates 46 are fixedly connected to the lower side of the end of the rack 43 away from the rolling roller. The side of the locking block 451 close to the rolling roller is arranged to be inclined in a direction away from each other and away from the rolling roller. The unlocking plates 46 correspond to the locking blocks 451 one by one, and the unlocking plates 46 can abut against the inclined surfaces on the locking blocks 451.

[0042] When driving the corresponding moving arm 3 to move, the telescopic rod of the hydraulic cylinder 443 extends and pushes the second gear 441 to mesh with the corresponding rack 43 through the first motor 442. At this time, the first motor 442 drives the second gear 441 to rotate and drives the corresponding rack 43 to move in the direction close to the rolling roller, and pushes the moving arm 3 to drive the moving rod 41 to move in the direction close to the rolling roller. The first spring 42 is deformed, and the locking block 451 completely enters the moving rod 41 under the squeezing of the side wall of the mounting frame 2. At this time, the second spring 452 is compressed until the detection roller 32 abuts against the side wall of the rolling roller. At this time, the second spring 452 recovers its deformation and pushes the locking block 451 to move in the direction away from the moving rod 41, thereby cooperating with the first spring 42 and fixing the moving rod 41 on the side wall of the mounting frame 2, and driving the sliding seat 312 and the sliding shaft 311 through the driving member 34 and the screw 313 to drive the grinding wheel 21 to continue to move until it abuts against the side wall of the rolling roller, so as to facilitate grinding the surface of the rolling roller.

[0043] When unlocking, the driving rack 43 drives the unlocking plate 46 to move toward the locking block 451 and squeeze the locking block 451 until the locking block 451 completely enters the moving rod 41. At this time, the first spring 42 recovers and drives the moving rod 41 to drive the moving arm 3 to reset, which is convenient for replacing the grinding wheel 21 with different fineness to grind the roller.

[0044] Reference Figure 3 and Figure 5 A cavity 35 is provided in the movable arm 3, and the end of the lead screw 313 away from the roller is inserted into the cavity 35. A mounting hole 36 adapted to the rack 43 and connected to the cavity 35 is provided at the end of the movable arm 3 away from the roller, and the end of the rack 43 close to the roller can enter the cavity 35. A blocking block 5 for blocking the mounting hole 36 is inserted and slidably connected at the end of the movable arm 3 close to the movable rod 41, a blocking groove 37 connected to the mounting hole 36 is provided on the side wall of the movable arm 3, and a blocking member 51 for driving the blocking block 5 to move is provided on the movable rod 41.

[0045] Reference Figure 3 , Figure 4 and Figure 5 The driving member 34 includes a first bevel gear 341 which is sleeved and fixedly connected to one end of the lead screw 313 inserted into the cavity 35. One side of the first bevel gear 341 is meshed with a second bevel gear 342 which is rotatably connected to the inner wall of the movable arm 3. A first gear 343 is provided on the side of the second bevel gear 342 away from the lead screw 313. When the end of the rack 43 close to the rolling roller enters the cavity 35, it can mesh with the first gear 343, and a control member 6 connecting the second bevel gear 342 and the first gear 343 is provided between the two.

[0046] Reference Figure 5 The control member 6 includes a ratchet 61 located on the side of the second bevel gear 342 close to the first gear 343 and coaxial with the second bevel gear 342 and fixedly connected. A fixing hole 3431 is provided at the axis of the first gear 343. The ratchet 61 is inserted into the fixing hole 3431 and coaxial with the first gear 343. Two ratchet pawls 62 arranged opposite to each other and meshing with the ratchet 61 are hinged on the inner side wall of the first gear 343. When the rack 43 moves in the direction close to the roller, the second bevel gear 342 is fixed relatively to the first gear 343 through the ratchet 61 and the ratchet pawl 62.

[0047] When the rack 43 pushes the movable arm 3 to move in the direction close to the rolling roller, the end of the rack 43 abuts against the blocking block 5. When the movable arm 3 moves to the point where the detection roller 32 abuts against the side wall of the rolling roller, the blocking block 5 is driven to open the mounting hole 36 through the blocking piece 51. At this time, the rack 43 continues to be driven to move in the direction close to the rolling roller until the end of the rack 43 enters the cavity 35 and drives the first gear 343 to rotate. At this time, the ratchet 61 and the pawl 62 make the first gear 343 and the second bevel gear 342 relatively fixed. The first gear 343 drives the second bevel gear 342 to rotate and drives the first bevel gear 341 and the lead screw 313 to rotate, thereby driving the grinding wheel 21 to continue to move in the direction close to the rolling roller until it abuts against the side wall of the rolling roller.

[0048] When the rack 43 moves away from the roller and drives the movable arm 3 to reset, the ratchet 61 and the pawl 62 cause the first gear 343 and the second bevel gear 342 to rotate relative to each other, reducing the adverse effect of the rotation of the first gear 343 on the relative position of the grinding wheel 21 on the movable arm 3.

[0049] Reference Figure 4 and Figure 5 The blocking member 51 includes a blocking rod 511 with one end inserted into the moving rod 41 and located on the side where the locking block 451 is close to each other. The two sides of the blocking rod 511 close to the locking block 451 are set as inclined surfaces that are inclined away from the roller and close to each other. A third spring 512 is fixedly connected between the end of the blocking rod 511 close to the locking block 451 and the inner side wall of the moving rod 41 to connect the two. The other end of the blocking rod 511 is inserted into the blocking groove 37 and is set as an inclined surface that is inclined downwards towards the side close to the roller. The moving rod 41 and the moving arm 3 are both slidably connected to the blocking rod 511. When the blocking block 5 blocks the mounting hole 36, the end of the blocking rod 511 close to the roller is located at the lower side of the blocking block 5 and abuts against the lower side wall of the blocking block 5.

[0050] When the locking block 451 is fully inserted into the moving rod 41, the end of the blocking rod 511 close to the blocking block 5 is located at the lower side of the blocking block 5, the blocking block 5 blocks the mounting hole 36, and the third spring 512 is stretched. When the locking block 451 pops out and fixes the moving rod 41, the third spring 512 recovers its deformation and pulls the blocking rod 511 to move away from the roller until it is separated from the blocking block 5. At this time, the blocking block 5 slides downward and opens the mounting hole 36, which is convenient for driving the rack 43 to enter the cavity 35 and The driving screw 313 rotates, and when the grinding wheel 21 corresponding to this movable arm 3 completes grinding, the driving rack 43 moves in the direction away from the roller until the unlocking plate 46 squeezes the locking block 451 and completely enters the movable rod 41. At this time, the end of the locking block 451 squeezes the blocking rod 511 away from the inclined surface at one end of the roller and pushes the blocking rod 511 to move in the direction close to the blocking block 5, until the blocking rod 511 is close to the inclined surface at one end of the roller, pushing the blocking block 5 to move upward and block the mounting hole 36 again.

[0051] The implementation principle of a grinder in an embodiment of the present application is as follows: when the rack 43 pushes the movable arm 3 to move in a direction close to the rolling roller, the end of the rack 43 abuts against the blocking block 5. When the movable arm 3 moves to the detection roller 32 and abuts against the side wall of the rolling roller, the locking block 451 pops out and fixes the movable rod 41, and the third spring 512 recovers its deformation and pulls the blocking rod 511 to move in a direction away from the rolling roller until it is separated from the blocking block 5. At this time, the blocking block 5 slides downward and opens the mounting hole 36, and continues to drive the rack 43 to move in a direction close to the rolling roller until the end of the rack 43 enters the cavity 35 and drives the first gear 343 to rotate. At this time, the first gear 343 drives the second bevel gear 342 through the ratchet 61 and the pawl 62, which drives the first bevel gear 341 and the lead screw 313 to rotate, thereby driving the grinding wheel 21 to continue to move in a direction close to the rolling roller until it abuts against the side wall of the rolling roller.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
