[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The composite ceramic coating preparation equipment of this utility model embodiment will be described below with reference to the accompanying drawings.

[0021] like Figures 1-4As shown, the composite ceramic coating preparation equipment of this utility model includes: a preparation tank 1, which is a hollow cavity used to hold composite ceramic coating raw materials such as ceramic powder, binder, solvent, etc.

[0022] A discharge port is provided at the bottom of the tank, which is connected to the spray gun 3 through the connecting pipe 4. A valve (not shown in the figure) can be installed at the discharge port to control the flow of raw materials.

[0023] Opening 2 can be installed on top of preparation tank 1 and can be detachably connected by a snap or thread (not shown in the figure).

[0024] Spray gun 3 is connected to preparation tank 1 via connecting pipe 4.

[0025] The stirring mechanism includes a stirring motor 8, a shaft 9, a spiral blade 11, and a blade assembly block 10. The shaft 9 rotates at the center of the cover 2. The stirring motor 8 is fixed on the top surface of the cover 2. The output end of the stirring motor 8 is connected to one end of the shaft 9. The spiral blade 11 is set on the outer wall of the shaft 9 through the blade assembly block 10.

[0026] Spiral blade 11: Spiral structure, distributed along the shaft 9, with a gap of 2-5mm between the blade edge and the inner wall of the mixing tank 1 to achieve vertical convection mixing of raw materials.

[0027] When using it.

[0028] Filling raw materials: Open the cover 2, add ceramic powder, binder, solvent, etc. into the preparation tank 1, close the cover 2 and lock it.

[0029] Start-up: The stirring motor 8 drives the shaft 9 to rotate, and the spiral blades 11 rotate synchronously with the shaft. Utilizing the spiral thrust, the material at the bottom is conveyed upwards, while the material at the top falls due to gravity, forming an upward and downward circulating convection flow as shown in the stirring direction in the diagram. Assuming the shaft rotates clockwise, the spiral blades push the material upwards, and the liquid near the tank wall naturally falls back down. The blade assembly block 10 enhances connection stability and ensures uniform transmission of stirring torque.

[0030] Uniform mixing: Stir for 5-10 minutes for low-viscosity solvent-based raw materials and 15-30 minutes for high-viscosity paste-like raw materials, and control the mixing effect by adjusting the motor speed from 500 to 1500 rpm to achieve uniform dispersion of raw materials, such as full fusion of ceramic particles and binder.

[0031] Raw material conveying: Open the outlet valve of the mixing tank 1 or control the spray gun trigger to allow the mixed raw materials to flow into the spray gun 3 along the connecting pipe 4. A micro-pressure device (not shown in the diagram) can be installed inside the tank to assist in conveying, such as pneumatic pressurization, to improve the flowability of high-viscosity raw materials.

[0032] Spraying operation: The operator holds a spray gun 3 and sprays the material onto the surface of the substrate, such as metal parts or ceramic substrates. According to the coating requirements, the spray gun parameters, nozzle diameter, spraying distance, and pressure are adjusted to achieve a coating thickness of 0.1-2mm in one or multiple sprays.

[0033] Real-time stirring optional: If the viscosity of the raw material changes during the spraying process (such as solvent evaporation), the stirring motor 8 can be started for a short time (such as stirring for 30 seconds every 10 minutes). Through the secondary mixing of the spiral blades 11, the uniformity of the raw material is ensured, and spraying defects such as particle settling and binder stratification are avoided.

[0034] This embodiment realizes the "ready-to-use" operation of the composite ceramic coating preparation equipment: operation process: filling → stirring (mobile) → spraying, the whole process does not require a fixed workstation and can be completed by a single person.

[0035] In one embodiment of this utility model, it also includes a gun holder 5 and a triangular locking block 6. The gun holder 5 is disposed on the preparation tank 1, and the triangular locking block 6 is located inside the gun holder 5.

[0036] Specifically, the triangular locking block 6 is an elastic rubber or plastic block inside the gun holder 5, arranged in a triangular shape, which fixes the spray gun 3 through elastic clamping force, ensuring the portability of the equipment that can be picked up and used at any time.

[0037] In one embodiment of the present invention, a handle 7 and a handle 12 are also included. The handle 7 is connected to the lid 2, and the handle 12 is disposed on the outside of the preparation tank 1.

[0038] Specifically, the handle 12 is designed for hand grip, allowing for one-handed lifting of the entire device and enhancing its portability, making it easy to use anytime.

[0039] In one embodiment of this utility model, the helical blade 11 has a helical structure and the blade assembly block 10 has a disc-shaped structure, and the two are distributed sequentially along the axial direction of the shaft 9.

[0040] Specifically, the spiral wound around the outer wall of the shaft 9 with a uniform pitch of 20-30mm. When rotating, the spiral thrust transports the raw material at the bottom of the tank upward, forming longitudinal convection and realizing the vertical circulation and mixing of the raw material.

[0041] Blade assembly block 10: It is a disc-shaped structure with a diameter slightly smaller than the inner wall of the mixing tank 1. It is fixed in the middle of the shaft 9 or above the spiral blade 11. When it rotates synchronously with the shaft, it disperses the aggregated raw materials to the tank wall through centrifugal force and shearing action. Together with the spiral blade 11, it forms a three-dimensional mixing effect of "longitudinal conveying + transverse dispersion" to improve the mixing uniformity.

[0042] Axial distribution: The two are arranged sequentially from top to bottom or from bottom to top along the shaft 9, such as the blade assembly block 10 located 5-10cm above the spiral blade 11. Through the synergistic effect of different structures, efficient stirring is achieved in a limited tank.

[0043] In one embodiment of this utility model, a cover buckle 13 is provided on the top surface of the cover 2, and the cover buckle 13 is provided with multiple sets of control keys, which are connected to the stirring motor 8.

[0044] Control buttons: Located on the surface of cover 13, such as a circular area, including: Power button: Short press to turn on / off, long press for 3 seconds to activate the child lock indicator light.

[0045] Speed ​​control key: Adjust the stirring motor speed by turning the knob to adapt to raw materials of different viscosities.

[0046] Timer button: Set the mixing time from 1 to 15 minutes, with a default of 5 minutes. The machine will automatically stop after the set time to avoid overmixing.

[0047] When using it.

[0048] Filling raw materials: Open the cover 2, add ceramic powder, binder, solvent, etc. into the preparation tank 1, close the cover 2 and lock it.

[0049] Start-up: The stirring motor 8 drives the shaft 9 to rotate, and the spiral blades 11 rotate synchronously with the shaft. Utilizing the spiral thrust, the material at the bottom is conveyed upwards, while the material at the top falls due to gravity, forming an upward and downward circulating convection flow as shown in the stirring direction in the diagram. Assuming the shaft rotates clockwise, the spiral blades push the material upwards, and the liquid near the tank wall naturally falls back down. The blade assembly block 10 enhances connection stability and ensures uniform transmission of stirring torque.

[0050] Uniform mixing: Stir for 5-10 minutes for low-viscosity solvent-based raw materials and 15-30 minutes for high-viscosity paste-like raw materials, and control the mixing effect by adjusting the motor speed from 500 to 1500 rpm to achieve uniform dispersion of raw materials, such as full fusion of ceramic particles and binder.

[0051] Raw material conveying: Open the outlet valve of the mixing tank 1 or control the spray gun trigger to allow the mixed raw materials to flow into the spray gun 3 along the connecting pipe 4. A micro-pressure device (not shown in the figure) can be installed inside the tank, such as pneumatic pressurization to assist conveying and improve the flowability of high-viscosity raw materials.

[0052] Spraying operation: The operator holds a spray gun 3 and sprays the material onto the surface of the substrate, such as metal parts or ceramic substrates. According to the coating requirements, the spray gun parameters, nozzle diameter, spraying distance, and pressure are adjusted to achieve a coating thickness of 0.1-2mm in one or multiple sprays.

[0053] Real-time stirring optional: If the viscosity of the raw material changes during the spraying process, such as solvent evaporation, the stirring motor 8 can be started for a short time, such as stirring for 30 seconds every 10 minutes. Through the secondary mixing of the spiral blades 11, the uniformity of the raw material is ensured, and spraying defects such as particle sedimentation and binder stratification are avoided.

[0054] In summary, the composite ceramic coating preparation equipment of this utility model embodiment realizes the "ready to use, mix and spray" instant operation mode, which significantly improves the coating preparation efficiency and quality in miniaturized scenarios, and is especially suitable for R&D, maintenance and small-batch production scenarios with high requirements for portability and flexibility.
