It should be appreciated that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of these exemplary embodiments to those skilled in the art.
Referring to fig. 1, a paint spray control system 100 according to a preferred embodiment of the present invention includes a hydraulic pump 110, a pressure reducing valve 120, at least one pressure sensor 130, and a controller 140. The coating may be an aqueous or oily paint.
Wherein the hydraulic pump 110 is respectively communicated with the hydraulic line 170 and the paint line 180, and controls the pressure of the paint in the paint line 180 according to the pressure of the hydraulic oil that the hydraulic line 170 enters the hydraulic pump 110. The hydraulic pump 110 is preferably a piston hydraulic pump to ensure that it can stably discharge paint.
A relief valve 120 may be disposed on the hydraulic line 170 upstream of the hydraulic pump 110 in communication with the hydraulic pump 110, the relief valve 120 being configured to control the pressure of hydraulic oil entering the hydraulic pump 110. The pressure reducing valve 120 is preferably an electrically controlled piston type pressure reducing valve or an electrically controlled diaphragm pressure reducing valve, so as to ensure the stability of the pressure of the hydraulic oil.
The pressure sensor 130 is used to sense the pressure of hydraulic oil or paint. When the pressure sensor 130 senses the pressure of the hydraulic oil, it is disposed on the hydraulic line 170 between the relief valve 120 and the hydraulic pump 110; when the pressure sensor 130 senses the pressure of the paint, it is disposed on the paint line 180 downstream of the hydraulic pump 110.
The controller 140 is electrically connected to the hydraulic pump 110, the pressure reducing valve 120, and the pressure sensor 130, and is configured to control the opening degree of the pressure reducing valve 120 according to the pressure sensed by the pressure sensor 130. So that the value of the pressure sensor 130 is maintained at a preset value. The preset value is the pressure value of the paint with the optimal paint rate or the pressure value of the hydraulic oil when the paint with the optimal paint rate.
According to the paint spraying control system, the pressure of the paint is kept constant by controlling the pressure reducing valve, so that the paint can be kept under the pressure with the optimal paint coating rate, the paint can be saved, and the cost is saved.
Optionally, the paint spray control system 100 may also include a spray device (not shown), a hydraulic oil feed device (not shown), and a paint feed device (not shown). The spray device and the hydraulic pump 110 may be in fluid communication via a paint line 180, the spray device being configured to receive paint from the hydraulic pump 110 and to spray it. The hydraulic pump 110 may be in fluid communication with the hydraulic oil delivery device via a hydraulic line 170 and the paint delivery device may be in fluid communication with the hydraulic pump 110 via a paint line 180. To increase the efficiency of the use of hydraulic oil, the paint spray control system 100 also includes a hydraulic oil return device (not shown) in fluid communication with the hydraulic pump 110, such as through a hydraulic line 170, for draining hydraulic oil from the hydraulic pump 110.
Continuing with reference now to FIG. 1, the paint spray control system 100 may further include a flow meter 150 and a drive 160. A flow meter 150 is provided on the paint line 180 downstream of the hydraulic pump 110 to detect the flow rate and the flow velocity of the paint discharged from the hydraulic pump 110.
The driving device 160 is configured to drive the workpiece to be sprayed to move a predetermined distance. The spray control system according to the invention is preferably applied in the context of spraying containers, i.e. the workpiece to be sprayed may be a container. When spraying, the driving means 160 drives the container to move within the spraying range of the spray head of the spraying apparatus. Wherein the predetermined distance may be a distance that allows the container to pass entirely through a spraying range of the spraying apparatus. The drive 160 preferably comprises a frequency converter which can be used to adjust the speed of movement of the workpiece to be sprayed. Illustratively, the driving device 160 may further include a motor and a dragging device, the dragging device pulls the container to move under the action of the motor, and the frequency converter may control the power of the motor.
In order to minimize the amount of paint consumed during spraying, the controller 140 is also electrically connected to both the flow meter 150 and the drive 160 and is configured to control the speed at which the drive 160 drives the workpiece to be sprayed to adjust the time required for the workpiece to be sprayed to move a predetermined distance, i.e., the time required to complete one spray. And enabling the flow rate of the paint of the workpiece to be sprayed in the time of finishing one-time spraying to be a preset value. That is, the spraying time is changed so that the amount of paint consumed to spray one complete workpiece to be sprayed is unchanged.
For example, please refer to fig. 2. When the spray head is clogged, the flow rate of the paint is reduced while the value of the pressure sensor 130 is maintained. At this time, the controller 140 controls the frequency converter to reduce the moving speed of the container, i.e., to increase the spraying time. So that the thickness of the surface coating of the container is not changed and is maintained at the most paint-saving thickness. Therefore, the spraying time is controlled by adjusting the moving speed of the workpiece to be sprayed, so that the flow of the nozzle paint can be kept stable under the condition of changing, the thickness of the coating is uniform, and the minimum paint consumption is kept. The wear of the nozzle is opposite to the above-mentioned blocking, and will not be described here again.
Preferably, to prevent the flow meter 150 from being plugged, the flow meter 150 may be a coriolis mass flow meter, since paint is easily attached to the pipe wall, so as to avoid an increase in measurement error caused by long-term use of the flow meter 150.
In addition, the controller 140 may determine the operation of each device of the paint spray control system 100 according to the proportional relationship K1 between the pressure value P detected by the pressure sensor 130 and the flow rate V detected by the flow meter 150. For example, the wear condition of the nozzle of the spraying device and the smoothness condition of each pipeline of the paint spraying control system 100 can be judged, and whether each device has abnormal conditions in operation can be timely found.
In summary, according to the paint spraying control system of the present invention, the pressure of the paint is kept constant by controlling the pressure reducing valve, and the moving speed of the workpiece is driven by the driving device to change the spraying time period, so that the paint is kept at the pressure with the optimal paint application rate while the paint spraying amount is kept constant, thereby achieving the effects of saving the paint and saving the cost.
