[0032] It should be noted that the utility model is a strip-shaped puffed food oil brushing device. When in use, first, the device is installed on a horizontal platform, then the lower oil cover 35 needs to be screwed, and then the oil to be brushed on the strip-shaped puffed food is added to the inside of the oil bottle 29, and then the oil cover 35 is reversely screwed on the oil bottle 29 to form a sealed space inside the oil bottle 29, and then the valve 30 is opened to allow the oil inside the oil bottle 29 to flow into the two steel wire hoses 31, and then the oil will enter the inside of the two oil pans 21 through the two oil filling pipes 28, and then the oil will enter the inside of the oil pans 21. Before the oil level inside the two oil pans 21 does not submerge the lower ends of the two oil filling pipes 28, outside air will enter the inside of the oil bottle 29 through the two oil filling pipes 28, the two steel hoses 31 and the valve 30, and at the same time, the oil inside the oil bottle 29 will flow into the inside of the two oil pans 21 respectively. When the oil level inside the two oil pans 21 submerges the lower ends of the two oil filling pipes 28, the oil will block outside air from entering the two oil filling pipes 28, and then the inside of the oil bottle 29 will not flow into the inside of the two oil pans 21 due to the atmospheric pressure when no external air enters.

[0033] Then the user can turn the lower fixing bolt 34, and then the user can turn the crank 18, so that the crank 18 drives the connecting shaft 13 to rotate, and the connecting shaft 13 can drive the swing rod 16 and the first plug-in shaft 14 movably connected at both ends of the swing rod 16 to rotate, and the two first plug-in shafts 14 can respectively push the two second plug-in shafts 15 to move through the two intermediate rods 17, because the two second plug-in shafts 15 are respectively movably plugged into the two movable plates 4 and the two movable plates 4 are fixedly installed on the two sliders 3, under the restriction of the two second plug-in shafts 15 and the two sliders 3 on the slide rail 2, the two movable plates 4 will move in two opposite directions with the connecting shaft 13 as the center, and at the same time, the two movable plates 4 drive the two sliders 3 to slide on the slide rail 2, and the two movable plates 4 will also drive the two roller shafts 5 and the connecting parts on the roller shafts 5 to separate as shown in FIG. Figure 3 Then the user can simultaneously control the control power supply to energize the two motors 11 in the forward and reverse directions respectively, so that the two motor shafts rotate in the forward and reverse directions respectively, and the two motor shafts drive the two roller shafts 5 to rotate in the forward and reverse directions respectively through the gear sets in the two reduction boxes 10, and the two roller shafts 5 that rotate in the forward and reverse directions respectively drive the eight oil brushes 8 on the two installation rollers 6 to rotate around the two roller shafts 5 in the forward and reverse directions respectively through the two driving installation rollers 6 and the eight installation plates 7 on the two installation rollers 6, and the eight oil brushes 8 that rotate in the forward and reverse directions respectively around the two roller shafts 5 on the two installation rollers 6 will be stained with oil when they rotate to the inside of the two oil pans 21, and then the excess oil is scraped off by the two scrapers 22 respectively, and then the user can introduce the strip-shaped puffed food from above the guide roller 32, pass between the two roller shafts 5, and then bypass from the bottom of the brush roller 33, and then The strip-shaped puffed food enters the next process, and then the user can pull the crank 18 in the reverse direction to make the connecting shaft 13 rotate in the reverse direction, and then the connecting shaft 13 drives the swing rod 16 and the two first plugging shafts 14 at both ends of the swing rod 16 to rotate, and the two first plugging shafts 14 respectively pull the two second plugging shafts 15 to move in the direction of the position of the connecting shaft 13 through the two intermediate rods 17, and the two second plugging shafts 15 can pull the two movable plates 4 to move, and the two movable plates 4 will also drive the two roller shafts 5 and the connecting parts on the roller shafts 5 to move in the direction of the position of the connecting shaft 13 until the crank 18 returns to the original position, and then the user needs to screw the fixing bolt 34 back to the original position, and at the same time apply oil and rotate around the two roller shafts 5 in the forward and reverse directions respectively. The eight oil brushes 8 can brush oil on both sides of the strip-shaped puffed food at the same time;

[0034] When the oil brush 8 is stained with the strip-shaped puffed food crumbs, since the eight oil brushes 8 on the two installation rollers 6 rotate around the two roller shafts 5 in the forward and reverse directions respectively, the eight oil brushes 8 on the two installation rollers 6 can comb out the strip-shaped puffed food crumbs on the oil brush 8 by passing through the combing teeth 27 on the two collecting boxes 24 respectively. In addition, the oil entering the two collecting boxes 24 can be leaked into the two oil pans 21 through the filter holes 26 provided on the two collecting boxes 24. If the oil in the two oil pans 21 is reduced, so that the oil surface in the two oil pans 21 does not submerge the lower ends of the two oil filling pipes 28, the outside air will enter the oil bottle 29 through the two oil filling pipes 28, the two steel wire hoses 31 and the valve 30, and the oil in the oil bottle 29 will also flow into the two oil pans 21 respectively, so as to complete the purpose of replenishing the oil in the two oil pans 21.

[0035] If the oil brush 8 needs to be replaced, the seven connecting bolts 9 on one side of the oil brush 8 to be replaced need to be screwed, and the user can remove the oil brush 8 to be replaced, and then install the new oil brush 8 and screw the seven connecting bolts 9.
