Coating referring to the metal products, plastics, wood and other materials by processing, surface coverage protective or decorative layer, with the development of industrial technology, the development of coating technology and equipment in China has experienced from manual to mechanical equipment to the development process, the automatic production line of coating process flow generally: pretreatment, grinding to paint, leveling and drying or curing, waste treatment. Painting equipment is complete mechanical equipment used these coating process.
 

Coating equipment industry in the 50's true origins of the introduction of technology in the Soviet union. From the beginning of the 60's, due to the development of light industry, first in the bicycle manufacturing industry appeared the automation production line, this period mainly task of China's coating industry is still in the main corrosion. But with the development of our national economy, and the development of foreign painting technology, through the introduction of technology and foreign exchange of technology, coating technology of our country began rapid development, in the automatic coating production, application, electrostatic spraying and electrophoretic coating technology of powder coating development and promotion of technology, especially in household electric appliances, daily hardware, steel furniture, the vigorous development of aluminum components, electrical appliances, automobile industry and other fields, so that the coating equipment has made obvious progress and development.
 

Characteristic

(1) coating equipment cannot do without solvent has many parts to be solvent.

(2) the paint is flammable and explosive substances, many parts of the device to make flame retardant explosion-proof treatment.

(3) coating process requires more sophisticated, high equipment precision requirement

(4) equipment load is low, there is little heavy equipment.

(5) coating equipment easier to plan the assembly line, saving manpower.

(6) the running speed is slow.
 

Rules of operation

(a) equipment operating personnel must be familiar with all kinds of mechanical structure, performance and operation and maintenance methods, shall be used, the person responsible for the.

(two) the operation of woodworking machinery, should wear working clothes, tie cuffs, female comrades must wear work hat, braided into the cap; don't wear gloves, scarves and other operations.

(three) machinery started must test each component before work, after normal operation can begin to work. Note: if the one or two ignition not; the best burning machine fan air while the gas furnace discharge is finished second times to test machine.

(four) shaft, chain, pulley, belt and other moving parts should be set on the device, a protective cover and a protective plate.

(five) the mechanical operation if not normal circumstances or other failure, should be immediately cut off the power supply, the parking overhaul.

(six) peripheral equipment for flammable materials shall be strictly prohibited fireworks.

(seven) the debugging and the maintenance of equipment, must cut off the total power.
 

Requirement

(1) where the use of toxic, irritating and flammable material process should be placed in a separate building, or arranged in the plant specializes in separate areas, and are equipped with personal protective equipment and fire equipment.

(2) in the workshop shall be provided to eliminate the draught passage facilities, prevent the spread of fire facilities such as automatic fire doors, fire smoke baffle, water curtain etc..

(3) the need to safely reach above equipment jobs, should be installed with protective railings and stairs bridge. Plant ground and bridge channel should be laying anti-skid floor.

(4) a pedestrian path should not be piled up equipment, object and wire crossing points, channel width not less than 1m.

(5) the pipeline in the work area over walking below must be laying protective net, to prevent falling objects.

(6) the excess paint and paint waste, should isolate the stacked in storehouse special coatings.

Environmental protection measures

(1) the work must be worn when the corresponding mask and mask, must have good ventilation measures.

(2) part of the solvent volatilization of relatively large, must be a gas collecting device, to prevent the poisonous gas diffusion.
 

Process design

In order to make the painting equipment utilization rate reached a high level, it needs to establish a reasonable coating production lines, one must first determine the production program, perfect process design, program planning, and then to manufacture equipment, design and installation. So the process design, project planning is the foundation to build a production line, correct, reasonable process has decisive influence on the production operation and product quality will be.

Process design content mainly includes: the surface of the workpiece before processing method, coating methods, coating, spraying performance environment, process planning.

Maintenance instructions
 

A painting line

The 1.1 painting the blast and exhaust pipe should be checked every day the seal, not leaking, leaking.

The 1.2 chamber body top filter cotton is subject to regular inspection, timely remove dust or replace. Clean up once every March, replaced once a year.

1.3 in the circulating water tank regularly adding coagulant for paint fog, filter, water tank, grid should be cleaned regularly (every week). Lacquer mist coagulant every two months on a.

1.4 fan belt every six months to replace a (also visible production situation).

1.5 polishing cleaning indoor filter bag every two weeks to clear a (also visible production situation).

Using the 1.6 painting fan motor lubricating way (Huang You) cup per month to a circle (cup to timely refueling), add lubrication oil every three months refueling time, beating Huang You lubrication gas once every two months.
 

Two, product chain

2.1 store chain guide roller and butter lubrication once every half a year (in batches of).

2.2 store chain trolley duckbill head with butter lubrication once every half a year.

The 2.3 store chain spray lubrication spray lubrication once every week, time shall not be less than four hours. (domestic demand timely replenishment of oil tank)

The 2.4 store chain tensioner driving devices are respectively fixed bolts monthly check
