DETAILED DESCRIPTION

[0027] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a water injection device for coating production, including mobile base 1, water tank 2 is fixed on the top of mobile base 1, water adding cover 201 is screw-connected on the outer surface upper end of water tank 2, water outlet cylinder 3 is penetrated in the left end of water tank 2, water injection pipe 301 is penetrated in the bottom end of water outlet cylinder 3, servo motor 4 is fixed in the top end middle of water outlet cylinder 3, drive shaft 401 that is penetrated to the inside of water outlet cylinder 3 is fixed on the output end of servo motor 4, quantitative roller 5 is fixed on the bottom end of drive shaft 401, quantitative groove 6 is set in the front and rear ends of quantitative roller 5, after servo motor 4 operates, drive shaft 401 can drive quantitative roller 5 to rotate a week, so that quantitative groove 6 on quantitative roller 5 is turned over position, to allow quantitative groove 6 equal volume water output, and with drive shaft 401 every cycle rotation a week indicates uniform speed output water quantity, and the volume of quantitative groove 6 can be designed according to actual demand, for example: the volume of each quantitative groove 6 is 50mm, then drive shaft 401 every cycle rotation a week indicates that quantitative water injection 50mm, so that quantitative water injection is accurate, simultaneously, because the sealing gasket 501 of quantitative roller 5 left and right ends is tightly attached with symmetrically arranged sealing groove 7, so that when quantitative roller 5 rotates, it does not cause error by losing extra water, sealing groove 7 and quantitative groove 6 are all set as circular arc, and the radian of sealing groove 7 and quantitative groove 6 is one fourth of quantitative roller 5, so that when quantitative groove 6 rotates with quantitative roller 5, sealing groove 7 can be closed.

[0028] The side wall in the middle of the bottom end of the water outlet cylinder 3 is provided with symmetrically arranged sealing grooves 7, which are matched with the quantitative roller 5. The top end of the water tank 2 is fixedly provided with an electric push rod 8, the bottom end of the electric push rod 8 penetrates into the inside of the water tank 2 and is fixedly provided with a pressing plate 9. The lower end of the outer surface of the water tank 2 is hingedly provided with a sealing door. The lower end of the inside of the water tank 2 is slidingly connected with a mesh frame 10. The mesh frame 10 is placed with an activated carbon plate 11. When tap water, river water and other industrial water is poured into the water tank 2, the water needs to pass through the mesh frame 10 and the activated carbon plate 11 placed inside before being output. The mesh frame 10 is made of metal or plastic material and has a large pore size, mainly used for filtering large particle impurities in water, such as solid substances such as silt, leaves and branches. This step can prevent large particle impurities from entering the activated carbon plate 11 for secondary pollution, prolonging the service life of the activated carbon plate. The activated carbon in the activated carbon plate 11 is a very effective adsorbent material, which can adsorb organic matter, chlorine, odor and some harmful substances such as heavy metal ions in water. The activated carbon plate 11 is placed in the mesh frame 10, which can make the water contact the activated carbon through the action of water flow, thereby removing these substances. At the same time, when filtering water, the electric push rod 8 can also be used as a driving force to push the pressing plate 9 downward through its linear motion to extrude and pressurize, which helps to accelerate the speed of water flow through the filter medium, thereby improving the water filtration efficiency. After the pressure increases, the water flow can pass through the mesh frame 10 and the activated carbon plate 11 in a short time, reducing the residence time, thereby effectively removing the impurities in the water. In some cases, the filter medium may be gradually blocked by impurities, particles or precipitated substances in the water, reducing the filtering effect. The extrusion action of the electric push rod 8 pushing the pressing plate 9 helps to keep the filter medium with higher permeability, reduce the deposition of impurities, thereby effectively preventing the blocking phenomenon and prolonging the service life of the filter material.

[0029] The initial position of the pressing plate 9 is above the water filling cover 201. The pressing plate 9 is also located directly above the mesh frame 10, so that after the pressing plate 9 moves downward and passes through the water filling cover 201, the upper end of the inside of the water tank 2 can be completely blocked, so that the water can be pushed and extruded during the pressing process of the pressing plate 9, accelerating the water flow through the mesh frame 10 and the activated carbon plate 11.

[0030] The pressing plate 9 is rectangularly arranged to match the cross section of the water tank 2. The pressing plate 9 is fixedly provided with a sealing ring 901 which closely fits the inner wall of the water tank 2, so that the tightness between the pressing plate 9 and the water tank 2 can be maintained when the pressing plate 9 moves downward, thereby playing a role in extruding the water flow.

[0031] The control panel is installed at the upper right end of the water tank 2, and the PLC board electrically connected with the servo motor 4, electric push rod 8 and other electronic devices is arranged in the control panel. The PLC is a core control element in industrial automation, and is widely used in the operation control of various devices. The PLC can realize accurate control of these devices through electrical connection with servo motors, electric push rods and other devices. Servo motors are usually used in high-precision and high-dynamic performance occasions, while electric push rods are generally used in scenarios that require linear motion, such as mechanical arms and adjusting mechanisms. The control of these devices can be realized through logical control, speed regulation and position control functions of the PLC. The connection mode of the PLC with the servo motor and the electric push rod is usually through digital or analog output / input, relays, frequency converters, drivers and other control methods. Through electrical connection, the PLC can send signals to adjust the action of the servo motor and the push rod to complete tasks such as position control and speed regulation.

[0032] Symmetrical trapezoidal slide rails are fixed at the left and right ends of the water tank 2, and the trapezoidal slide rails are located at the four corners of the mesh frame 10. The design of the trapezoidal slide rails enables the mesh frame 10 to smoothly slide in the slide rails, thereby greatly simplifying the operation of taking out the mesh frame 10. When it is necessary to replace or clean the mesh frame 10, the mesh frame 10 can be easily taken out of the water tank 2 by sliding, without complicated disassembly steps. Moreover, the shape and structure of the trapezoidal slide rails can ensure that the mesh frame 10 is stably positioned in the water tank 2, preventing it from shifting or shaking. In this way, both the filtering effect when the water flows through the mesh frame 10 and the prevention of damage to the mesh frame 10 due to instability during operation can be achieved.
