[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a roller cleaning apparatus. A roller cleaning machine is a device used to clean machined rollers to remove impurities from their surface. (Refer to...) Figure 1 The roller cleaning device includes an oil inlet device 1, an oil pipe 2, a nozzle 3, a fixing frame 4, and a cleaning table 5. The oil inlet device 1 provides cleaning oil and the power to transport the cleaning oil. The oil pipe 2 transports the cleaning oil and fixes the direction of the oil path into the nozzle 3. The nozzle 3 sprays cleaning oil onto the rollers. One end of the oil pipe 2 is connected to the oil inlet device 1, and the other end is connected to the nozzle 3. The fixing frame 4 is used to fix the nozzle 3. The fixing frame 4 is fixed to the housing on one side of the roller cleaning machine. The nozzle 3 passes through and is fixed relative to the fixing frame 4. The oil outlet of the nozzle 3 faces the cleaning table 5, which is the worktable for cleaning the rollers. The cleaning table 5 has a cleaning tank 51. During rinsing, the conveyor belt carries the rollers through the cleaning tank 51, and the nozzle 3 sprays cleaning oil to clean the rollers. The nozzle 3 can rotate relative to the fixing frame 4, so the rinsing direction and rinsing position can be adjusted by rotating the nozzle 3, but the nozzle 3 is always aligned with the cleaning tank 51 so that the cleaning oil always falls into the cleaning tank 51 to clean the rollers.

[0028] Reference Figure 2Several oil pipes 2 and nozzles 3 are provided, the specific number is not limited, and the oil pipes 2 and nozzles 3 are connected one-to-one. The mounting frame 4 has mounting holes 41 for the nozzles 3 to pass through and be fixed. The mounting holes 41 are opened along the length of the mounting frame 4 so that several nozzles 3 are arranged along the roller conveying direction. The nozzles 3 pass through the mounting holes 41 so that both ends of the nozzles 3 are located on both sides of the mounting frame 4. A fixing nut 31 is threaded onto the nozzle 3. The fixing nuts 31 are installed on both sides of the mounting frame 4. After tightening, the fixing nuts 31 press against the surface of the mounting frame 4, thus fixing the nozzles 3 to the mounting frame 4. To increase the contact area and distribute pressure, a shim 311 can be placed between the fixing nut 31 and the mounting frame 4. To ensure that the shim 311 abuts against the surface of the mounting frame 4, the outer diameter of the shim 311 must be larger than the diameter of the mounting hole 41. By adjusting the fixing nut 31, the nozzles 3 can rotate circumferentially around the central axis of the mounting hole 41. After circumferential rotation, the nozzles 3 remain aligned with the cleaning tank 51. The circumferential rotation of the nozzle 3 allows the rinsing position to be closer to the inlet of the roller feed, thereby increasing the rinsing time. Furthermore, the mounting hole 41 is preferably an oblong hole, the opening shape of which allows the mounting holes 41 of each nozzle 3 to be interconnected, so that the nozzle 3 can slide along the length of the mounting hole 41 to facilitate adjustment of the arrangement position of the nozzle 3.

[0029] The nozzle 3 includes a flat part 32 and a vertical part 33. The nozzle 3 is L-shaped. The flat part 32 is connected to the oil pipe 2. The flat part 32 is fixed to the fixed frame 4 by a mounting hole 41. The fixing nut 31 is threaded onto the flat part 32. The vertical part 33 is aligned with the cleaning tank 51 to rinse the roller. The flat part 32 rotates circumferentially relative to the fixed frame 4, so that the vertical part 33 rotates about the flat part 32 as the axis of rotation, thereby changing the rinsing position and direction of the nozzle 3.

[0030] Reference Figure 2 and Figure 3 The cleaning table 5 includes two retaining strips 52, and the cleaning tank 51 is formed by the two retaining strips 52 spaced apart. The retaining strips 52 serve to limit and position the rollers, and the two retaining strips 52 restrict the rollers relatively within the cleaning tank 51 so that the nozzles 3 can be relatively accurately aligned with the rollers for rinsing. Furthermore, the two ends of the retaining strips 52 are connected to fixing bolts 521, and connecting plates 6 are bolted to the housing on both sides of the roller cleaning machine. The connecting plates 6 have a first sliding groove 61, which is an oblong hole. The first sliding groove 61 is preferably set perpendicular to the cleaning tank 51. The fixing bolts 521 slide against the connecting plates 6 within the first sliding groove 61, so that the two retaining strips 52 move closer or further apart, thereby adjusting the width of the cleaning tank 51 to clean rollers of different sizes.

[0031] The fixing bolt 521 can be directly inserted and fixed to the clip 52. Alternatively, as another embodiment, the two ends of the clip 52 are bolted to a first adjusting block 522. The first adjusting block 522 includes an integrally formed fixing plate 523 and a moving plate 524. The fixing plate 523 is fixed to the side wall of the clip 52, and the moving plate 524 abuts against the connecting plate 6. The fixing bolt 521 passes through the moving plate 524 and slides in the first sliding groove 61.

[0032] Reference Figure 4 and Figure 5 The mounting bracket 4 includes an integrally formed connecting part 42 and a mounting part 43. The connecting part 42 is used to connect and fix to the housing of the roller washing machine, and the mounting part 43 is used to install and fix the nozzle 3. The mounting hole 41 is located in the mounting part 43. A second adjusting block 7 is fixed on the housing on one side of the roller washing machine, and the connecting part 42 is connected to the second adjusting block 7. A slider 421 is fixedly connected to the connecting part 42, and the second adjusting block 7 has a cavity 71 for the slider 421 to slide.

[0033] Reference Figure 3 and Figure 5 Specifically, a fastening bolt 422 passes through the connecting part 42 and the slider 421. The nut of the fastening bolt 422 abuts against the inner wall of the slider 421 to fix the slider 421 and the connecting part 42 relative to each other. A second sliding groove 72 is provided on the second adjusting block 7, which connects the cavity 71 to the outside. Correspondingly, a sliding groove is also provided on the connecting part 42 for the fastening bolt 422 to slide. The fixing frame 4 slides in the cavity 71 via the slider 421. The opening direction of the second sliding groove 72 is the same as the lifting direction of the fixing frame 4. When the slider 421 slides upward, the fixing frame 4 rises; when the slider 421 slides downward, the fixing frame 4 falls. Therefore, the height of the fixing frame 4 can be adjusted to suit different usage scenarios.

[0034] Reference Figure 4 and Figure 5 In a preferred embodiment, the second adjusting block 7 includes an integrally connected horizontal plate 73 and vertical plate 74. The two vertical plates 74 are connected to both ends of the horizontal plate 73. The horizontal plate 73 abuts against the top of the housing of the roller washer, and the vertical plates 74 are located on both sides of the housing of the roller washer. The vertical plate 74 near the nozzle 3 is connected to the connecting part 42, and the slider 421 is located inside the vertical plate 74 near the nozzle 3. A fastening screw 741 is provided on the vertical plate 74 near the nozzle 3, and the fastening screw 741 abuts against the side wall of the housing of the roller washer, so that the second adjusting block 7 is fixed to the housing of the roller washer.

[0035] Reference Figure 1The oil inlet device 1 includes a fixed base 11 and a liquid pump connected to each other. The fixed base 11 fixes one end of the oil pipe 2, and the liquid pump is used to pump out the cleaning oil. The fixed base 11 has several oil inlets 111, which are connected to a storage tank containing cleaning oil. One end of the oil pipe 2 is connected to and communicates with the oil inlets 111.

[0036] The implementation principle of the roller cleaning device in this embodiment is as follows: one end of the oil pipe 2 is connected to the oil inlet 111 and fixed on the fixed base 11, and the other end of the oil pipe 2 is connected to and communicates with the flat part 32. The nozzle 3 passes through the mounting hole 41 and is fixed on the mounting part 43 by the fixing nut 31. By adjusting the fixing nut 31, the vertical part 33 rotates circumferentially around the flat part 32 as the rotation axis, thereby adjusting the spray direction and position of the nozzle 3. The mounting hole 41 is an oblong hole, which allows the nozzle 3 to slide within the mounting hole 41 to adjust the arrangement position of the nozzle 3. By sliding the fixing bolt 521 in the first slide groove 61 to adjust the position of the adjusting strip 52, the width of the cleaning groove 51 is changed. By sliding the slider 421 in the second slide groove 72, the fixed frame 4 can be raised and lowered to adjust the spray height of the nozzle 3. Therefore, the roller cleaning device in this embodiment can be adjusted in multiple dimensions to adapt to different usage scenarios and rinsing requirements.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
