[0067] The frame 1 has a cleaning tank 11 fixedly installed on it. In this embodiment, a spray head is installed at the top inner part of the cleaning tank 11. During cleaning, the spray head sprays cleaning oil onto the linear guide rail inside the cleaning tank 11 to assist in cleaning. The cleaning tank 11 is used to collect the sprayed cleaning oil for recycling. It should be noted that a demagnetizer 12 for eliminating the magnetism of impurities is also provided at the front end of the cleaning tank 11. The demagnetizer 12 is a conventional device in the prior art, so it will not be described in detail. A rust-preventive oil spraying device is also provided at the rear end of the cleaning tank 11. The rust-preventive oil spraying device also uses a spray head to spray rust-preventive oil onto the linear guide rail inside the cleaning tank 11. Its structure is relatively conventional, so it is not shown in the attached drawings. In this embodiment, both the cleaning oil and the rust-preventive oil are equipped with oil circulation and recovery devices for circulating spraying.

[0068] The conveying mechanism is arranged in the cleaning tank body 11 and is used for conveying the linear rail. In the embodiment, the conveying mechanism comprises conveying rollers 21, conveying frames 22, a transmission chain and a conveying motor. It should be noted that the conveying frame 22 comprises two parts, i.e., a first conveying frame and a second conveying frame. The first conveying frame and the second conveying frame are the same in structure. The first conveying frame and the second conveying frame are both fixedly installed on the two sides of the cleaning tank body 11 and are arranged along the length direction of the cleaning tank body 11. The two ends of the conveying roller 21 are rotatably connected with the first conveying frame and the second conveying frame respectively. After the linear rail is placed on the conveying roller 21, the conveying motor drives the plurality of conveying rollers 21 to rotate through the transmission chain, so as to convey the linear rail into the cleaning tank body 11. Since the transmission chain and the conveying motor are conventional devices in the prior art, they are omitted in the drawings.

[0071] The first mounting frame 4 is fixedly installed on the first conveying frame and the second conveying frame. In the embodiment, a plurality of rod bodies 41 are fixedly arranged between the two first mounting frames 4. A plurality of first through holes 311 are formed in the cross beam 31. The rod bodies 41 are inserted into the first through holes 311, so that the cross beam 31 is movably arranged between the two first mounting frames 4 along the width direction of the cleaning tank body 11.

[0072] The top of the first cleaning roller 32 is provided with a transmission head 321. The transmission heads 321 are tensioned with a transmission belt 322. The transmission belt 322 is used for transmissionally connecting the adjacent first cleaning rollers 32. The first driving assembly drives one of the five first cleaning rollers 32 to rotate, so as to drive the five first cleaning rollers 32 to synchronously rotate and clean the two sides of the linear rail. It should be noted that the first driving assembly is arranged at the middle position of the cleaning tank body 11, and thus the first driving assembly is transmissionally connected with the first cleaning roller 32 located at the middle position.

[0073] In the embodiment, the first transmission assembly is arranged between the two cross beams 31 and is used to drive the two cross beams 31 to move synchronously in opposite directions.

The two cross beams 31 are both provided with a connecting column 312. The two ends of the connecting piece 52 are respectively sleeved on the connecting columns 312 of the two cross beams 31 through the waist-shaped holes 521. When the push plate 63 drives one cross beam 31 to move, the cross beam 31 drives the other cross beam 31 to move synchronously in the opposite direction through the connecting piece 52, so as to realize the synchronous adjustment of the first cleaning rollers 32 on the left and right sides of the linear rail.

[0075] In the embodiment, the width adjustment assembly includes a mounting beam 61, a width motor 62 and a push plate 63. The two sides of the mounting beam 61 are fixedly connected with the first mounting frame 4 through fixing bolts. The width motor 62 is fixedly installed on the mounting beam 61 through fixing bolts. The push plate 63 is slidably connected with the mounting beam 61 and can move along the length direction of the mounting beam 61. The push plate 63 is fixedly connected with the side surface of the cross beam 31 through fixing bolts. The width motor 62 is drivingly connected with the push plate 63. Specifically, a column body 631 with a threaded hole is fixedly installed on the push plate 63. A screw rod 621 is fixedly connected with the output shaft of the width motor 62 and is screwed in the threaded hole, so as to realize the driving connection between the width motor 62 and the push plate 63. When the width motor 62 works, the push plate 63 is driven to move through the screw rod 621 and the column body 631. The push plate 63 drives the cross beam 31 to move, so as to realize the distance adjustment between the two groups of first cleaning assemblies.

[0076] In the embodiment, the first driving assembly comprises a shaft body 71, a transmission member 72 and a driving motor 73. The shaft body 71 is rotatably installed on the mounting beam 61. The driving motor 73 is fixedly installed on the mounting beam 61 by fixing bolts. The output shaft of the driving motor 73 is fixedly connected with the shaft body 71. The push plate 63 is provided with a mounting hole. The transmission member 72 is rotatably installed in the mounting hole. The transmission member 72 is slidably installed on the shaft body 71. The transmission member 72 can move along the length direction of the shaft body 71, so that the push plate 63 is slidably connected with the mounting beam 61. The push plate 63 can move along the length direction of the mounting beam 61. The first cleaning roller 32 corresponding to the position of the transmission member 72 is drivingly connected with the transmission member 72. Specifically, the transmission head 321 corresponding to the position of the transmission member 72 is provided with a first transmission gear 3211. The transmission member 72 is provided with a second transmission gear 721. The first transmission gear 3211 is engaged with the second transmission gear 721. When the driving motor 73 works, the first cleaning roller 32 on the two cross beams 31 is synchronously driven to rotate, so as to clean the linear rail.

[0077] The drying mechanism is installed in the cleaning tank body 11 and is used for drying the cleaning oil on the surface of the linear rail. Specifically, the drying mechanism comprises an air duct assembly and a fan 86. The air duct assembly comprises a bottom plate 81 fixedly installed in the cleaning tank body 11, a top plate 82 slidably moving along the height direction of the cleaning tank body 11 and two side plates 83 slidably moving along the width direction of the cleaning tank body 11. The bottom plate 81 and the two side plates 83 and the top plate 82 and the two side plates 83 are connected with sealing folding pieces 84. The sealing folding pieces 84 are used for sealing the bottom plate 81 and the side plates 83 and the top plate 82 and the side plates 83. The bottom plate 81, the top plate 82, the side plates 83 and the sealing folding pieces 84 form an air duct 85 with adjustable size. The output end of the fan 86 is communicated with the air duct 85 through a pipeline. By changing the positions of the top plate 82 and the two side plates 83, the size of the air duct 85 can be adjusted, so that the size of the air duct 85 matches the size of the linear rail. The air blown by the fan 86 can pass through the surface of the linear rail along the air duct 85, so as to improve the drying efficiency. Multiple linearly arranged fans 86 are not needed to dry the linear rail, so as to reduce the energy consumption and save the production cost.

[0078] In the embodiment, the side plate 83 is provided with a plurality of sliding shafts. The conveying roller 21 corresponding to the positions of the sliding shafts is slidably connected with the sliding shafts. The conveying roller 21 is slidably connected with the side plate 83 through the sliding shafts, so that the side plate 83 can move along the width direction of the cleaning tank body 11.

The driving plate 87 is slidingly installed on the conveying frame 22 and can move along the length direction of the conveying frame 22. The driving plate 87 is in transmission connection with the side plate 83. One end of the first connecting rope 88 is fixedly connected with the driving plate 87, and the other end is in transmission connection with the cross beam 31 of the corresponding first cleaning assembly. When the cross beam 31 of the first cleaning assembly moves, the first connecting rope 88 drives the driving plate 87 to move. The driving plate 87 makes the two side plates 83 close to each other, reduces the distance between the two side plates 83, and thus reduces the width of the air duct 85.

[0080] In the embodiment, a plurality of first wedges 871 are arranged on the driving plate 87, and a plurality of second wedges 832 corresponding to the first wedges 871 are arranged on the side plate 83. A first inclined surface is arranged on the first wedge 871. The first inclined surface is arranged on the driving plate 87 side and inclines from the end away from the driving member to the end close to the driving member. A second inclined surface is arranged on the second wedge 832 and is in abutment with the first inclined surface. When the cross beam 31 drives the first wedge 871 to move to the end of the cross beam 31 through the first connecting rope 88, the first wedge 871 extrudes the second wedge 832 and drives the second wedge 832 to move along the width direction of the cleaning tank 11, so that the two side plates 83 close to each other.

[0081] In the embodiment, a connecting plate 89 is arranged between the driving plate 87 and the conveying frame 22. A sliding rail 891 is formed in the connecting plate 89. One side of the driving plate 87 is slidingly installed in the sliding rail 891, so as to achieve the sliding connection between the driving plate 87 and the conveying frame 22.

One end of the first extension spring 892 is fixedly connected with the connecting plate 89, and the other end is fixedly connected with the driving plate 87. A second reset member is arranged between the two side plates 83 and the conveying frame 22. The second reset member is a second extension spring 833. The second extension spring 833 is used to drive the second wedge 832 and the first wedge 871 to abut tightly. When the cross beam 31 of the first cleaning assembly moves reversely, the first connecting rope 88 relaxes. The first extension spring 892 and the second extension spring 833 reset the two side plates 83, so as to increase the width of the air duct 85.

[0082] In the embodiment, a guide assembly is arranged between the cross beam 31 and the driving plate 87, and the guide assembly comprises the first mounting plate 9 and a plurality of guide wheels 91.
