The limiting plate is provided with limiting posts 1081 corresponding to the limiting holes of the resin plate, and the limiting posts fix the resin plate.
[0059] In one embodiment of this utility model, the fixing plate and the limiting plate are provided with corresponding through holes (not shown in the figure), which ensure that wastewater can fall off.
[0060] In this embodiment, the circulating liquid dispensing assembly includes a storage tank 201, a water pump 202, a liquid dispensing pipe 203, a liquid dispensing nozzle 204, a recovery tank 205, a recovery pipe 206, a recovery box 207, a water pump 208, a liquid dispensing pipe 209, a liquid dispensing nozzle 210, and a recovery tank 211. The storage tank is located in the plate washing machine body and has a storage space for storing solvent. The water pump is located on one side of the storage tank and has an inlet valve. The water pump has an inlet and an outlet. The inlet is connected to the storage tank via a pipe, and one side of the outlet pipe is connected to the outlet of the pump. A branch pipe is located on the other side of the outlet pipe to transfer the solvent. A pair of outlet nozzles are provided, positioned on the top of the plate washing machine. One side of each nozzle is connected to the branch pipe of the outlet pipe, and a set of outlet ports is located at the bottom of each nozzle. These nozzles deliver the solution to the resin plate. A collection tank is located at the bottom of the liquid outlet nozzle. The bottom of the collection tank has a liquid outlet hole for solvent recovery. The top of the recovery pipe is connected to the collection tank for solvent transfer. A collection box is located at the bottom of the plate washing machine body. The top of the collection box is connected to the recovery pipe for solvent storage. A water pump is located on one side of the collection box. The inlet of the water pump is connected to the collection box through a pipe. One side of the liquid outlet pipe is connected to the outlet of the water pump. The other side of the liquid outlet pipe is provided with a diversion pipe. A pair of liquid outlet nozzles are provided. The liquid outlet nozzles are located at the top of the plate washing machine body. One side of the liquid outlet nozzles is connected to the diversion pipe of the liquid outlet pipe. The bottom of the liquid outlet nozzles is provided with a set of liquid outlets for delivering the solution to the resin plate. A collection tank is located at the bottom of the liquid outlet nozzles. The bottom of the collection tank is provided with a drain pipe 2111.
[0061] The working principle of this circulating liquid outlet component is as follows: The prepared solvent is placed in a storage tank, then a water pump extracts the solvent from the tank and delivers it through an outlet pipe to an outlet nozzle. The outlet nozzle then sprays the solvent onto the resin plate through its outlet, thus performing a fine wash on the resin plate. The wastewater generated during washing drips into a recovery tank, then flows through a recovery pipe to a recovery box. A water pump then extracts the wastewater from the recovery box and delivers it through an outlet pipe to an outlet nozzle. The outlet nozzle sprays the wastewater onto the resin plate through its outlet hole, thus performing a pre-wash on the resin plate. The secondary wastewater generated during washing is then... The wastewater from the first recycling tank is discharged. It is worth noting that this working principle is the working principle of the waste liquid circulation component, not the process of cleaning the resin board. The actual operation of the plate washing machine is to first pre-wash the resin board and then perform fine washing. During the first operation, the first water pump starts working first, but there is no wastewater in the recycling tank. Therefore, during the first cleaning, the solvent needs to be put into the recycling tank to ensure the normal operation of the plate washing machine. After subsequent operations, the recycling tank is no longer filled with water; only the storage tank needs to be filled with water. At the same time, the wastewater generated after fine washing has few impurities and can be used as pre-wash water.
[0062] In this embodiment, the roller brush assembly includes a rotary motor 301 and a cleaning roller 302. The rotary motor is disposed in the body of the plate washing machine, with the rotating end of the rotary motor facing the inner side of the plate washing machine body. One side of the cleaning roller is in contact with the rotary motor, and the cleaning roller can clean the resin plate under the drive of the rotary motor.
[0063] In this embodiment, the reciprocating cleaning assembly includes a rotary motor 401, a rotating disk 402, a guide sleeve 403, a cleaning brush 404, and a hinge rod 405. The rotary motor is located on one side of the plate washing machine body, with its rotating end facing upwards. The bottom of the rotating disk is connected to the rotating end of the rotary motor, and a connecting post is provided on the top of the rotating disk. The guide sleeve is located in the frame and has a guide hole. The two sides of the cleaning brush are slidably disposed in the guide sleeve, allowing the cleaning brush to move within the guide sleeve. One side of the hinge rod is hinged to the cleaning brush, and the other side of the hinge rod is hinged to the connecting post of the rotating disk. The hinge rod drives the cleaning brush to reciprocate.
[0064] In this embodiment, the washing machine body is provided with a moving groove 501, which provides space for the movement of the fixed plate and the limiting plate.
[0065] In this embodiment, the rotary motor is either a stepper motor or a servo motor.
[0066] Example 2
[0067] like Figures 1-7As shown, the difference between this embodiment and embodiment 1 is that, in this embodiment, a fixed bracket 601 and a fan 602 are provided on one side of the plate washing machine body. The fixed bracket is located at the top of the plate washing machine body, and an installation space is provided at the bottom of the fixed bracket. The fan is located at the bottom of the fixed bracket, and the air outlet of the fan is directed towards the plate washing machine body. After the resin plate is washed, there will be residual moisture on the resin plate. The fan is used to initially remove the moisture from the resin plate.
[0068] The working principle of this utility model:
[0069] During processing, the limiting holes on the resin plate are engaged with the limiting posts of the limiting plate. The conveyor motor drives the transmission shaft to rotate, which in turn drives the drive sprocket to rotate synchronously. Simultaneously, the drive sprocket drives the driven sprocket to rotate via the transmission chain. This movement of the transmission chain also moves the fixed plate and the limiting plate, thus moving the resin plate forward. When the resin plate reaches the bottom of the first liquid outlet nozzle, the first water pump extracts wastewater from the recovery tank and delivers it to the first liquid outlet nozzle through the first liquid outlet pipe. The first liquid outlet nozzle sprays the wastewater onto the resin plate through the outlet holes. Simultaneously, the rotary motor drives the cleaning roller to rotate, cleaning the resin plate on the limiting plate. When the roller moves below the cleaning brush... The rotary motor drives the rotating disk to rotate, and the rotating disk drives the hinge rod to move. The hinge rod simultaneously drives the cleaning brush to reciprocate in the guide sleeve, thereby cleaning the resin board. The secondary wastewater generated during cleaning is discharged through the discharge pipe. When the resin board moves to the bottom of the liquid outlet nozzle, the water pump starts, thereby drawing out the solvent in the liquid outlet tank and delivering it to the liquid outlet nozzle. Then, the resin board is finely cleaned by the roller brush assembly and the reciprocating cleaning assembly. The wastewater generated falls into the recovery tank and flows back to the recovery box through the recovery pipe. The limit plate carries the cleaned resin board out of the washing machine body, and then the staff removes the resin board. The limit plate is then reset, thus completing the cleaning of the resin board.
