[0036] Please refer to Figure 1 , this application provides an automatic feeding control system for painting, including a liquid storage tank 10, a feeding mechanism 20, a discharging mechanism 30, a stirring mechanism 40, a replenishing mechanism 50, and a control mechanism 60. Among them, the liquid storage tank 10 is provided with a feeding port 11 and a discharging port 12. The feeding mechanism 20 is connected to the feeding port 11, and the discharging mechanism 30 is connected to the discharging port 12. The feeding mechanism 20 includes a feeding member 21, a liquid inlet member 22, and a power member 23. The feeding member 21 and the liquid inlet member 22 are connected to the feeding port 11 in communication, and the power member 23 is connected to the liquid inlet member 22. The discharging mechanism 30 is in communication with the liquid storage tank 10 and is used to convey the liquid in the liquid storage tank 10 to the painting production line. The stirring mechanism 40 includes a stirring member 41 and a driving member 42. The driving member 42 drives the stirring member 41 to rotate and is used to stir the materials in the liquid storage tank 10. The replenishing mechanism 50 is connected to the power member 23 and is used to replenish materials into the liquid inlet member 22. The control mechanism 60 is electrically connected to the power member 23 and the control switch of the painting production line respectively.

[0037] Understandably, the replenishing mechanism 50 can feed materials to the production line according to the results of the bath liquid parameters, eliminating the need for manual feeding. Not only is the feeding timely and the number of feeding times reduced, but also it is not easy to have situations such as mis-feeding, missed feeding, and inaccurate feeding, reducing the fluctuation of the bath liquid parameters and ensuring the stable quality of the body obtained by processing. There will also be no waste, saving manpower and material resources at the same time.

[0038] Specifically, the feeding member 21 is a hopper provided on the liquid storage tank 10. The inlet of the hopper protrudes from the liquid storage tank 10, and the powdery raw material can be added into the liquid storage tank 10 from the position of the hopper. The liquid inlet member 22 is a pipeline connected to the feed inlet 11, and the power member 23 is connected to the liquid adding pipeline. The power member 23 can be a metering pump, a diaphragm pump, etc. When the power member 23 is started, the raw material in the liquid inlet member 22 can be pumped into the liquid storage tank 10 to achieve feeding of the liquid storage tank 10.

[0039] Further, the power member 23 is provided at the top position of the liquid storage tank 10, and the replenishing mechanism 50 can be connected to the liquid inlet member 22 through the power member 23.

[0040] Specifically, the replenishing mechanism 50 includes a replenishing liquid pipe 51 and a valve 52. The replenishing liquid pipe 51 is connected to the power member 23. When the power member 23 is started, the supplementary material can be pumped into the liquid storage tank 10 through the replenishing liquid pipe 51 to achieve replenishment of the liquid storage tank 10. The valve 52 is provided on the replenishing liquid pipe 51, and the liquid inlet amount and liquid inlet speed of the replenishing liquid pipe 51 can be controlled by adjusting the opening size of the valve 52. It is convenient to stably input the chemicals required for the vehicle body and avoid waste caused by excessive feeding.

[0041] Preferably, a flow meter 53 is provided on the replenishing liquid pipe 51. The replenishing amount of the replenishing liquid pipe 51 can be accurately observed by observing the flow meter 53, and the measured replenishing amount is continuously input to ensure the stability of the bath liquid parameters. The flow meter 53 can be directly purchased, and the model is not limited.

[0042] Exemplarily, the stirring member 41 can adopt structures such as a stirring paddle and a stirring wheel. In this embodiment, the stirring paddle is preferably used, and the stirring is sufficient. The driving member 42 is provided at the top of the liquid storage tank 10, and the upper end of the stirring member 41 passes through the liquid storage tank 10 and is connected to the driving member 42. The driving member 42 can be a motor, a gearbox, etc., as long as it can drive the stirring member 41 to rotate.

[0043] Further, the discharging mechanism 30 is set as a discharging pipe 31. One end of the discharging pipe 31 is connected to the discharging port 12 at the bottom of the liquid storage tank 10, and the other end of the discharging pipe 31 is connected to the electrophoresis tank to supply liquid to the electrophoresis tank. Preferably, a pump is provided on the discharging pipe 31. When the pump is started, the liquid material in the liquid storage tank 10 can be pumped to the electrophoresis tank through the discharging pipe 31.

[0044] Of course, in other embodiments, a pump may not be provided on the discharging pipe 31, and the discharging pipe 31 replenishes the liquid storage tank 10 through the liquid level drop. Or the pump is provided in the electrophoresis tank, so that the discharging pipe 31 replenishes the liquid storage tank 10.

[0045] Further, the control mechanism 60 can adopt a PLC controller, a single-chip microcomputer controller, etc. The control mechanism 60 is electrically connected to the power component 23 and the control switch of the painting production line respectively. Control the power component 23 and the control switch of the painting production line to turn on and off simultaneously. That is, when the production line is started, the feeding system is also started, and when the production line stops, the feeding system also stops accordingly. This avoids waste caused by continuous feeding. Regularly check whether the conveying equipment and the flow state are normal during production, and deal with it in time when it is abnormal.

[0046] In one embodiment, the automatic painting feeding control system further includes an early warning mechanism 70 for monitoring and warning the material height in the liquid storage tank 10. During daily production, the early warning mechanism 70 can detect according to the liquid level in the liquid storage tank 10, and remind or give an alarm when the liquid level is too low to avoid emptying. Personnel can supplement the required chemicals regularly according to the alarm, reducing the number of times of manual feeding.

[0047] Exemplarily, the early warning mechanism 70 includes a liquid level gauge 71 provided on the liquid storage tank 10, such as a liquid level sensor. Of course, in other embodiments, the early warning mechanism 70 may further include a warning light. The liquid level gauge 71 and the warning light are both electrically connected to the control system. When the liquid level gauge 71 detects that the liquid level is too low, it can feedback a signal to the control system, and the control system then controls the warning light to light up to remind the operator.

[0048] In one embodiment, the automatic painting feeding control system further includes a cleaning mechanism 80 for self-cleaning in the liquid storage tank 10. It is used when the chemicals in the tank need to be replaced or the liquid storage tank 10 needs to be cleaned.

[0049] Specifically, the cleaning mechanism 80 includes a liquid inlet pipe 81 and a liquid outlet 82. The liquid outlet 82 is provided at the bottom of the liquid storage tank 10. The liquid inlet pipe 81 is provided at the top of the liquid storage tank 10 and is connected to the liquid storage tank 10. In this embodiment, a valve 52 is provided on the liquid inlet pipe 81 to control the opening and closing of the liquid inlet pipe 81. A liquid outlet pipe 83 is connected to the liquid outlet 82, and a valve 52 is also provided on the liquid outlet pipe 83 to control the opening and closing of the liquid outlet pipe 83.

[0050] Understandably, when the chemicals in the tank need to be replaced or the liquid storage tank 10 needs to be cleaned, turn off the power component 23, and open the valve 52 on the liquid inlet pipe 81 to clean the inside of the liquid storage tank 10 through the liquid inlet pipe 81. If necessary, the driving part 42 can be started to drive the stirring part 41 to rotate. After cleaning, close the valve 52 on the liquid inlet pipe 81, and open the valve 52 on the liquid outlet pipe 83 until the sewage in the liquid storage tank 10 is drained out.

[0051] Preferably, the bottom of the liquid storage tank 10 is set as an inclined plane 13, and the liquid outlet 82 is provided at a position corresponding to the lower side of the inclined plane 13. It is more convenient for the sewage to be discharged from the side of the liquid outlet 82.

[0052] In this embodiment, the liquid storage tank 10 is made of acid- and alkali-resistant materials, such as 304 stainless steel, plastics, etc.

[0053] The working principle of the system is as follows: According to the daily production plan, the operator turns on the power component 23, uses the liquid inlet component 22 to transport chemicals into the liquid storage tank 10, and uses the feeding component 21 to supplement an appropriate amount of additives into the liquid storage tank 10. After the feeding is completed, the driving component 42 drives the stirring component 41 to rotate to stir and mix the chemicals in the tank. The mixed chemicals are continuously transported to the corresponding electrophoresis tank on the production line through the discharging mechanism 30.

[0054] When replenishing materials is needed, according to the test parameter results, turn on the power component 23 and open the valve 52 on the liquid replenishing pipe 51 to add materials to the liquid storage tank 10. Observe the flowmeter 53 synchronously to determine the amount of replenished materials.

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0056] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
