Technical Field

[0001] The utility model relates to the technical field of glaze spraying equipment, and in particular to a toilet glaze spraying system based on PID control. Background Art

[0002] During the production process of toilets, the steps of body molding, body glazing and transfer firing are sequentially carried out. The process of body glazing is commonly known as glazing. Common glazing methods are manual spraying and mechanical automatic spraying. The former is easier to control the quality of glazing and uses less glaze liquid, but the production efficiency is low and the working environment is not friendly to workers; the latter has a fast glazing speed and high production efficiency, but there is a problem of large glaze liquid consumption.

[0003] In the process of mechanical automatic glazing, especially for products of different specifications, if the flow rate of glaze liquid cannot be adjusted in time, the thickness of the glaze layer of the product will be either too small or too large, thus affecting the appearance of the product. Therefore, the problem of controlling the amount of glaze liquid is becoming more and more prominent.

[0004] Therefore, a new toilet glaze spraying system is urgently needed. Utility Model Content

[0020] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-2 As shown, this embodiment proposes a toilet glaze spraying system based on PID control, including:

[0022] The spraying assembly includes a driving member 1 and a nozzle 2, wherein the driving member 1 has a moving end, the moving end can move in space, and the nozzle 2 is arranged on the moving end;

[0023] The glaze supply assembly includes a glaze supply pump 3, a valve 4, a glaze supply tube 5 and a mass flow meter 6. One end of the glaze supply tube 5 is connected to the nozzle 2, and the other end is connected to the glaze supply pump 3. The valve 4 is arranged on the glaze supply tube 5, and the mass flow meter 6 is arranged between the valve 4 and the nozzle 2.

[0024] The controller is electrically connected to the driving member 1, the glaze supply pump 3 and the mass flow meter 6, and the controller can execute a PID control algorithm program.

[0025] In this embodiment, the PID-controlled toilet glaze spraying system includes a spraying component, a glaze supply component and a controller. Among them, the spraying component includes a driving component 1 and a nozzle 2. The driving component 1 has a driving end, and the driving end can move in space. This movement can be moved along the three-dimensional direction of the space. The nozzle 2 is arranged on the driving end. Therefore, the nozzle 2 can also move in space, which improves the convenience of glazing the toilet. The glaze supply component includes a glaze supply pump 3, a valve 4, a glaze supply tube 5 and a mass flowmeter 6. The output end of the glaze supply pump 3 is connected to the glaze supply tube 5. The valve 4 and the mass flowmeter 6 are both arranged on the glaze supply tube 5. The glaze outlet end of the glaze supply tube 5 is connected to the nozzle 2. The glaze supply pump 3 provides glaze liquid to the nozzle 2 through the glaze supply tube 5. The mass flowmeter 6 is connected to the controller. The controller can execute the PID control algorithm program. When the product model to be glazed is input into the controller, the corresponding control algorithm will be automatically called out in the controller, and then the amount of glaze liquid can be adjusted according to the real-time feedback of the mass flowmeter 6, thereby ensuring that the glaze liquid sprayed from the nozzle 2 is stable and controllable. This glazing method not only improves the glazing efficiency, but also ensures the glazing quality of the product and avoids the problem of uneven glaze thickness on the product surface.

[0026] Further, if Figure 1-2 As shown, this embodiment proposes that the driving member 1 is a robot arm.

[0027] In this embodiment, for more accurate and portable operation, the driving member 1 is selected as a robotic arm. The robotic arm is electrically connected to a controller, and under the operation of the controller, the end effector of the robotic arm can move freely in space. Among them, the robotic arm can be selected as a serial manipulator.

[0028] It should be specially noted that the driving member can also be selected in the form of a parallel manipulator, or even a three-degree-of-freedom or six-degree-of-freedom mechanism in space.

[0029] Further, if Figure 1-2 As shown, this embodiment proposes that the glaze supply tube 5 is divided into two sections, one section is a hard tube section, and the other section is a soft tube section. The hard tube section is provided with a glaze supply pump 3, a valve 4 and a mass flow meter 6, and the soft tube section is connected to the nozzle 2.

[0030] In this embodiment, since the nozzle 2 needs to move with the driving end of the driving member 1, and the nozzle 2 is connected to the glaze supply tube 5, the part connecting the glaze supply tube 5 and the nozzle 2 needs to be a flexible tube. The glaze supply tube 5 is divided into two sections, one section is a hard tube section, and the other section is a soft tube section, and the soft tube section is connected to the nozzle 2.

[0031] Further, if Figure 1-2 As shown, this embodiment proposes that the glaze supply assembly also includes a clamp 7, and the clamp 7 is connected to the hard pipe part.

[0032] In this embodiment, since the glaze supply tube 5 is divided into a hard tube part and a soft tube part, in order to avoid vibration of the hard tube part during use, the hard tube part is fixed to the wall or other external structures by a clip 7.

[0033] Further, if Figure 1-2 As shown, this embodiment proposes that the valve 4 is a solenoid valve and is electrically connected to the controller.

[0034] In this embodiment, when the valve 4 is selected as a solenoid valve, in order to improve the overall automation level of the device, the valve 4 is electrically connected to the controller so that the controller directly controls the valve 4 .

[0035] Further, if Figure 1-2 As shown, this embodiment further includes a cleaning pipe 8 , on which a cleaning valve 9 is provided, and one end of the cleaning pipe 8 is connected to the glaze inlet end of the glaze supply pipe 5 .

[0036] In this embodiment, since the glaze supply tube 5 will have residual glaze liquid after not being used, if it is not cleaned in time, it is easy to cause blockage. Therefore, the toilet glaze spraying system based on PID control also includes a cleaning tube 8, which is connected to the glaze supply pump 3 and is provided with a cleaning valve 9. When the valve 4 is closed and the cleaning valve 9 is opened, the glaze supply pump 3 draws clean water with the help of the cleaning tube 8, and the inside of the glaze supply pump 3 can be cleaned.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
