Then, use an overhead crane to quickly remove the guide roller 2.1 along with the bearings at both ends from the cleaning machine bracket 1, disconnecting the transmission connection between the guide roller 2.1 and the guide roller drive shaft 3.2, thereby greatly improving the disassembly and installation efficiency of the guide roller 2.1. After disassembly, the guide roller 2.1 can be ground and repaired with the bearings at both ends and the water-spraying disc 2.3 (when grinding the guide roller 2.1, since there is no bearing seat interference at both ends, the bearing outer sleeves at both ends can be used as a support and positioning reference), saving the work of installing and removing the bearings and water-spraying disc 2.3, further improving the grinding and maintenance efficiency of the guide roller 2.1. See the instruction manual appendix Figure 1 , 2The motor 4 is fixedly mounted on the motor support seat 1.4 on the outside of the upper crossbeam 1.1 on the right side of the upper part of the cleaning machine bracket 1. The output shaft of the motor 4 is connected to the guide roller drive shaft 3.2 of one of the guide roller drive assemblies 3 through a coupling, driving the guide roller drive shaft 3.2 of the guide roller drive assembly 3 to rotate. The guide roller drive shaft 3.2 then transmits power to the guide roller drive shafts 3.2 of the other guide roller drive assemblies 3 through the synchronous toothed belt 5, thereby driving all guide rollers 2.1 to rotate synchronously. See the instruction manual appendix Figure 12 The upper housing 7 is a rectangular thin-walled housing structure. Guide roller clearance grooves 7.1 are provided on the lower part of the left and right side panels, and two negative pressure air ducts 7.2 are provided on the top of the housing; see the appendix of the instruction manual. Figure 3 When the upper box 7 is installed, the lower part of the box wall panel is set in the water collection tank 5.2 of the lower box 5 and fixedly connected to the cleaning machine bracket 1 (the fixed connection structure is not shown in the figure); the lower box 6 and the upper box 7 enclose the guide roller 2.1 in the closed space formed by the lower box 6 and the upper box 7; the guide roller clearance groove 7.1 of the upper box 7 is set in the gap between the adjacent water-spraying trays 2.3 at both ends of the guide roller 2.1, and the two ends of the guide roller 2.1 extend through the guide roller clearance groove 7.1 to the outside of the upper box 7; the negative pressure air duct 7.2 is connected to an exhaust fan (not shown in the figure), and when the exhaust fan is working, a negative pressure is formed in the closed space formed by the lower box 6 and the upper box 7; See the instruction manual appendix Figure 3 Spray pipes 8 are also installed in the lower box 6 and the upper box 7. The spray pipes 8 are equipped with nozzles, and the spray nozzles are directed towards the guide roller 2.1.

[0017] When the metal foil spray cleaning machine is working, the metal foil is wrapped around the adjacent guide rollers 2.1 in a wave-like pattern. The rotation of the guide rollers 2.1 drives the metal foil to move through the closed space formed by the lower box 6 and the upper box 7. The nozzle sprays cleaning liquid onto the metal foil wrapped around the guide rollers 2.1 to clean the residual oil and foreign matter on the surface of the metal foil. During the cleaning process, the water mist in the closed space between the lower box 6 and the upper box 7 is prevented from escaping from the guide roller clearance groove 7.1 of the upper box 7, as well as the inlet and outlet, by negative pressure. The water remaining on the guide rollers 2.1 is thrown into the water collection tank 6.2 of the lower box 6 through the water-spinning discs 2.3 at both ends of the guide rollers 2.1, and then flows back into the lower box 6 through the drainage tank 6.2.1. When the guide roller 2.1 needs to be disassembled for grinding and maintenance, first use an overhead crane to remove the upper housing 7, remove the upper bearing seat 2.2.2 of the guide bearing seat 2.2, adjust the connection direction of the guide roller flat head 2.1.1 and the guide roller drive shaft flat groove 3.2.1 to be perpendicular, and then use an overhead crane to quickly remove the guide roller 2.1 along with the bearings at both ends from the cleaning machine bracket 1. This greatly improves the disassembly and installation efficiency of the guide roller 2.1, reduces the workload during guide roller disassembly and maintenance, improves guide roller maintenance efficiency, and thus improves the operating rate of the metal foil spray cleaning machine.
