The working principle is as follows: when the aluminum profile needs to be washed, sufficient water is injected into the water storage device, then the aluminum profile needing to be washed is placed on the top of the screen plate, then the aluminum profiles on the top of the screen plate are washed by the water stored in the water storage device, the washed water flows into the lower part of the first frame body through the screen plate, the water pump is controlled to work, the water pump pumps the washed water back into the water storage device through the hose for recycling, when in washing, the left-right moving device pushes the first frame body to reciprocate left and right, thereby ensuring that the aluminum profiles placed on the top of the screen plate can be washed, when the aluminum profile is washed, the water pump is controlled to stop working, the first valve is opened, the water washed in the first frame body is discharged through the first water outlet pipe, when all the water after being washed in the first frame body is discharged, the first valve is closed, and finally the washed aluminum profile is taken down from the top of the screen plate.
Because the water storage device comprises a second frame body, a second water outlet pipe, a second valve, a water inlet pipe, a baffle, a plug and a first handle, the second frame body is arranged at the center of the top of the mounting frame, the second water outlet pipe is symmetrically arranged at the bottom of the second frame body in the left-right direction, the second valve is arranged on the second water outlet pipe, the water inlet pipe is arranged at the middle part of the left wall of the second frame body, the baffle is connected between the middle parts of the left wall and the right wall of the second frame body, the right part of the baffle is provided with a first through hole, the plug is plugged in the first through hole, the top of the plug is provided with the first handle, the top end of the hose is connected with the lower part of the right wall of the second frame body, when the aluminum profile needs to be washed, sufficient water is injected into the lower part of the second frame body through the water inlet pipe, meanwhile, when the aluminum profile needs to, and meanwhile, the water pump is controlled to work, and the water pump pumps the washed water back to the inner lower part of the second frame body through the hose for recycling. When the aluminium alloy washes the completion, control water pump stop work, the water that the lower part was used repeatedly in the second framework passes through the second outlet pipe and emits into in the first framework, and no longer flow back in the second framework, then open first valve, through the first outlet pipe water discharge first framework that will use repeatedly, after the water in the first framework is whole to be discharged, extract the stopper through first handle, the water at baffle top flows into the lower part in the second framework through first through-hole, then in the rethread second outlet pipe gets into first framework, wash the aluminium alloy in the first framework for the second time, the water that washes the completion directly discharges through first outlet pipe. When the water at the top of the baffle plate completely flows into the lower part of the second frame body through the first through hole, the plug is plugged into the first through hole through the first handle, when the water at the lower part of the second frame body is completely discharged into the first frame body through the second water outlet pipe, the second valve is closed, and when the water in the first frame body is completely discharged through the first water outlet pipe, the first valve is closed.
Because the left-right moving device comprises a second slide rail, a second slide block, a rack, a connecting rod, a first spring, a mounting plate, a motor and a sector gear, a second through hole is formed in the lower portion of the right wall of the mounting frame, the lower portion of the right side of the mounting frame below the second through hole is connected with the second slide rail, the top of the second slide rail is connected with the second slide block in a sliding mode, the left end of the second slide block is connected with the first spring, the left end of the first spring is connected with the lower portion of the right side of the mounting frame, the rack is arranged at the top end of the second slide block, the connecting rod penetrates through the second through hole, the left end of the connecting rod is connected with the lower portion of the right side of the first frame body, the mounting plate is arranged on the lower portion of the right side of the mounting frame above the second through hole, the motor, the motor drives the sector gear to rotate clockwise, the sector gear drives the rack to move leftwards, the rack drives the connecting rod and the second sliding block to move leftwards, the first frame body is driven to move leftwards, the first spring is compressed, when the sector gear rotates clockwise to a certain angle, the sector gear is separated from the rack, the first spring is restored to the original state, the second sliding block and the upper device of the second sliding block are pushed to move rightwards to reset, the first frame body moves rightwards to reset, when the sector gear rotates clockwise to be meshed with the rack again, the movement before the repetition. So relapse, through promoting first framework and lasting the side-to-side motion, guaranteed that the aluminium alloy that the otter board top was placed can all be washed, when the aluminium alloy washes the completion back, when treating sector gear and getting back to initial position, control motor stall.
Because the novel rubber ball drawing frame also comprises a second spring, a first fixed pulley, a second fixed pulley, a drawing wire and a rubber ball, the second spring is symmetrically connected at the left and right of the bottom in the first frame body, the top end of the second spring is connected with a screen plate, the screen plate is arranged in the first frame body, the first fixed pulley is arranged at the center of the bottom of the second frame body, the second fixed pulley is arranged at the middle part of the left side of the mounting frame, a third through hole is arranged at the middle part of the left wall of the mounting frame, the drawing wire is connected at the center of the top of the screen plate, the drawing wire bypasses the first fixed pulley, passes, when the aluminum profile is washed, the rubber ball is pulled downwards, the rubber ball pulls the screen plate to move upwards through the pull wire, the second spring is stretched, when the screen plate moves upwards to a proper height, the rubber ball is loosened, the second spring restores to the original state, the screen plate is pulled to move downwards to reset, and when the screen plate resets, the rubber ball is pulled downwards again. So relapse, shake repeatedly from top to bottom through the otter board for the aluminium alloy at otter board top can in time overturn, has guaranteed that washing of aluminium alloy is comprehensive.
Because still including hinge, apron and second handle, the left wall top of second framework is connected with the apron through the hinge rotary type, and apron top right side is equipped with the second handle, through the apron, prevents that external impurity from polluting the water at baffle top, has not only practiced thrift the water, has also improved the washing quality.
The control mode of the invention is automatically controlled by the controller, the control circuit of the controller can be realized by simple programming of a person skilled in the art, the invention belongs to the common knowledge in the field, and the invention is mainly used for protecting mechanical devices, so the control mode and the circuit connection are not explained in detail in the invention.
