1 Appearance of the equipment (for reference only, the actual product shall prevail)
2 Structural description of the equipment
(1) The cabinet is welded with square tubes and cold-rolled plates, and the surface is thermally sprayed after rust removal. The cabinet has good sealing and uses three layers of imported sound insulation materials for noise reduction.
(2) From left to right, there are two spray chambers, namely: A spray chamber with guns 1-2 on the front and B spray chamber with guns 3-4 on the back, forming a 2+2 spray mode. The spray gun scanning adopts a servo system, and the gun distance of each spray gun can be adjusted independently.
(3) The gold spray frame conveying system has been carefully designed. The conveying is carried out by a frequency converter. The conveying system runs smoothly and is durable.
(4) The spray gun scanning adopts a servo system. The gun distance of each spray gun can be adjusted independently. The moving 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 moving speed of the gold spray frame, etc.
(5) Upper exhaust dust removal system:
a. The upper exhaust dust removal efficiency is high. Through the U-shaped wind, the air volume inside the independent cabin is enhanced, which effectively removes excess dust and reduces the pollution of the core end face.
b. The wind force in the gold spray chamber is uniform, which saves energy significantly, reduces the dust removal capacity configuration, and reduces investment.
c. The equipment is beautiful, compact and reasonable.
3. Working principle of the equipment
This equipment uses two charged gold spray wires to collide during movement to generate a short-circuit current and form a high temperature to make the metal wire melt rapidly. The molten metal is sprayed onto the component by high-speed compressed air to form a gold spray layer. These four-gun, two-sided, independent spray chambers utilize a left-in, right-out conveyor system. The core-loading fixture is placed on the conveyor line and moves at a constant speed. Manual loading is performed in the loading area, and the fixture is then raised and pushed onto the conveyor belt. As the core passes through spray chamber A, the spray guns move up and down to spray the front surface with four guns. When the spray fixture reaches spray chamber B, the back surface is sprayed in the same manner, achieving the desired thickness. This completes the spraying process, and the core-loading frame is then automatically transported by the conveyor belt to the unloading area for 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 adopts a unique design of upper exhaust for dust removal;
a. It does not form vortexes, does not turn black or blue;
b. It removes dust quickly and causes little pollution;
c. The upper exhaust method is highly efficient, and the investment in the dust removal system is 20-30% less;
(5) The equipment is equipped with temperature and humidity detection functions.
(6) Equipped with Jisheng's unique dust removal system, the use effect is more significant
