1.Appearance of the device (for reference only, the actual product shall prevail)
2 Equipment structure description
(1) The equipment cabinet is welded with square tubes and cold-rolled plates, and the surface is thermally sprayed after rust removal. The cabinet has good sealing performance and uses three layers of imported sound insulation materials for noise reduction.
(2) From left to right, there are two spraying rooms, namely: A spraying room with guns 1-4 on the front and B spraying room with guns 5-8 on the back, forming a 4+4 spraying mode. The spray gun scanning adopts a servo system, and the gun distance of each spray gun can be adjusted independently.
(3) The spray frame conveying system has been carefully designed, and the conveying is carried out by the frequency converter. The conveying system runs smoothly and is durable.
(4) The spray gun scanning adopts a servo system, and the gun distance of each spray gun can be adjusted independently. The movement speed of the spray gun can be automatically adjusted through the digital input of the touch screen. The spray gun is equipped with an automatic dust blowing function. The movement speed of the spray frame, etc.;
(5) Top-Exhaust Dust Collection System:
A. Top-exhaust dust removal is highly efficient. The U-shaped airflow enhances the airflow within the independent chamber, effectively removing excess dust and reducing contamination on the core end surfaces.
B The airflow in the spray chamber is uniform, significantly saving energy, reducing dust removal capacity, and lowering investment.
C. The equipment is aesthetically pleasing, compact, and reasonably priced.
3. Operating Principle of the Equipment
This equipment utilizes the collision of two charged spray wires during movement, generating a short-circuit current and high temperatures that rapidly melt the wires. The molten metal is then sprayed onto the component by high-velocity compressed air, forming a spray coating. This eight-gun, two-sided independent spray chamber utilizes a left-in, right-out conveyor system. The core loading fixture is placed on a conveyor line and advances at a constant speed. Manual loading is performed in the loading area by raising the fixture and pushing it onto the conveyor belt. When the core passes through the A spraying chamber, the spray gun moves up and down to complete the first 4 spraying shots on the front side. When the spraying fixture moves to the B spraying chamber, the back side spraying is completed in one go in the same way according to the required thickness. At this point, all the spraying is completed, and then the core frame is automatically sent out by the conveyor belt to the unloading area to complete the unloading.
4. Features of the equipment
(1) The equipment has good stability and is easy to operate;
(2) The spray gun uses dynamic power supply, which does not block or explode the wire;
(3) The equipment has good sealing performance;
(4) It uses a unique design of upper exhaust to remove dust;
a. It does not form vortexes, does not turn black or blue;
b. It removes dust quickly and has low pollution;
c. The upper exhaust method is highly efficient, and the investment in dust removal is 20-30% less;
(5) The equipment is equipped with temperature and humidity detection functions.
(6) It is equipped with Jisheng's unique dust removal system, which makes the use effect more significant.
