The specific examples described in the following embodiments of the present invention are merely illustrative of specific implementations of the present invention and do not constitute limitations on the scope of the invention.
The following description is provided to further illustrate the embodiments of the present invention with reference to the accompanying drawings and specific examples.
Referring to fig. 1, the present invention provides an automatic spraying system for a press, comprising: the water storage device comprises a rack 10, a water storage pipe 20 arranged on the rack 10, a pulse water valve 60 connected with the water storage pipe 20, a water pump 30 connected with the water storage pipe 20 and a PLC (programmable logic controller) 40 connected with the pulse water valve 60; wherein,
the frame 10 comprises a cross frame 11 arranged above the conveying device 50;

Specifically, the frame 10 of the present invention is a support structure that is independently installed on the production line or a structure that is fixed on the press for supporting the water storage tube 20; the transverse frame 11 is vertical to the moving direction of the pre-wetted substrate, a plurality of branch ports are arranged on a water storage pipe 20 fixed on the transverse frame 11, and a shunt valve is assembled at the branch ports and connected with a pulse water valve 60 through a water pipe section; the PLC 40 can control the pulse water valve 60 to humidify the surface of the sheet material, and the PLC 40 controls the electric mechanism of the water pump 30 to pump the water in the water tank into the water storage pipe 20, so that the water pressure in the water storage pipe 20 can be kept within a set water pressure range to ensure the consistency of the water output of the water spray valve.
Preferably, the automatic spraying system of the press according to the present invention further comprises a water tank and a filter, wherein the water tank is connected with the water inlet of the water pump 30 through the filter. Specifically, the filter is capable of removing particulates from the water to prevent the particulates from plugging the pulsed water valve 60.
Preferably, the automatic spraying system of the press according to the present invention further comprises an angular velocity sensor disposed at the rotating shaft of the conveyor 50, and the angular velocity sensor is connected to the PLC controller 40. Specifically, the angular velocity sensor measures the transmission speed of the transmission device 50 and transmits a transmission speed signal to the PLC controller 40, and further the PLC controller 40 adjusts the modulation pulse according to the transmission speed, wherein, as the transmission speed is faster, the frequency and duty ratio of the modulation pulse are higher, and further the frequency at which the pulse water valve 60 is opened is higher and the opening time per cycle is longer; on the contrary, when the conveying speed is reduced, the water yield of the pulse water valve 60 in unit time is correspondingly reduced, so that the surface of the plate is uniformly humidified.

Specifically, the pressure sensor 21 periodically collects pressure values and transmits the pressure values to the PLC controller 40, the PLC judges whether the water pressure in the water storage pipe is within a set pressure range according to the pressure values, and if the pressure values are lower than the set pressure range, the PLC controls the water pump 30 to start pumping water of the water tank or other water supply equipment so as to increase the water pressure of the water storage pipe 20; conversely, the water pump 30 is turned off to keep the water pressure in the reservoir 20 from exceeding the normal operating pressure.
Furthermore, in one embodiment of the present invention, the pulsed water valve 60 may be selected to enter a continuous operation period while the water pump 30 is adjusted to a determined flow value and continuously supplies water to the reservoir 20, thereby maintaining the water output of the pulsed water valve 60 at the same flow value as the water supplied by the water pump 30.
Preferably, the automatic spraying system of the press machine according to the present invention further comprises an industrial personal computer connected to the PLC controller 40 for monitoring and modifying the operation parameters of the PLC controller 40. Specifically, the display interface of the industrial personal computer can display the switching frequency and the single-cycle opening time of the pulsed water valve 60, the working state of the water pump 30, the water pump flow value, the pressure state of the water storage pipe 20, the transmission speed of the transmission device 50 and the like; furthermore, partial parameters can be modified and adjusted according to actual use requirements, so that the plate material can be sprayed according to requirements.
In conclusion, according to the automatic spraying system of the press, the high atomization effect and the spraying uniformity are ensured by the associated control of the pulse water valve and the water pump; the precise control of the spraying water yield is ensured through the cooperative work of the pulse water valve and the PLC controller; the working pressure and the production safety of the water storage pipe are ensured through the pressure sensor and the PLC; the data is transmitted to the PLC through the angular velocity sensor, so that the water spraying amount of the lower surface of the plate material is kept consistent in different conveying speed states; the industrial personal computer realizes the work monitoring of the spraying system and the timely adjustment of the operation parameters.
