Aluminium Powder Coating Line

Product Description
Customer-based Automatic Powder Coating Line Design
Coating production line components:● Pre-treatment equipment:      The pre-treatment equipment can be divided into spray type, swimming immersion type and manual dip tank type, all of which are made of corrosion-resistant materials. Different treatment forms can be selected according to the product size, the structure is reasonable, and the ideal use effect can be achieved.      Commonly used spray pre-treatment features: the syrup sprays the surface of the product through the nozzle. Because the spray will generate a certain pressure, the surface of the workpiece can be well washed and has the characteristics of large-scale continuous operation, but the one-time investment is relatively large. The dosage of the syrup is also large, which is suitable for long and simple surface treatment.      The pre-spray treatment equipment system uses a centrifugal water pump to form a high-pressure atomization effect from the nozzle through the pipeline to achieve the purpose of cleaning. The utility model has the advantages of high-pressure atomization effect, cleans the surface of the workpiece, and recycles the cleaning liquid, thereby achieving the purpose of energy saving and environmental protection, generally suitable for mass production of the production line, and has good effects, and is widely used in household appliances, hardware, lighting, toys, automobiles. Parts and other industries. ● Drying and curing equipment:      The drying and curing furnace mainly provides a baking and curing temperature environment for the coating, and the hot air is circulated and heated in the oven, the heat efficiency is high, the temperature in the furnace is balanced, and energy is saved. The heat source can be widely selected from electricity, coal, oil, gas, and biological particles.      The oven insulation layer is filled with aluminum silicate cotton or rock wool. After the mechanism is formed, it is assembled in a plate shape; the oven structure is compact, solid and durable, and the heat insulation and sealing property is good; the temperature rise is fast, the temperature difference is small, and the energy saving effect is remarkable; The range, holding time, heating rate and automatic protection can be set by any program; it has simple operation, stable operation, complete automatic control, no need for personnel to be guarded; widely used for drying and curing of various products.      Common heating methods and features:      1. Electric energy heating: The equipment cost is low, the use cost is high, and there is no pollution.      2, fuel heating: equipment cost is slightly higher, the cost of use is general, slightly polluted.      3. Coal-fired heating: Low equipment cost, low cost of use and serious pollution.      4, particle heating: high cost of equipment, low cost of use, pollution.      5, gas heating: equipment cost is generally low, the use of low cost, no pollution. ● Powder & paint recycling equipment (commonly known as dusting room):           It consists of a chamber body, a powder spray gun, an automatic reciprocating machine, a powder supply device, a recovery device, an air suction device and an electric control.In order to obtain higher recovery efficiency and color change speed, large cyclone primary recovery and secondary recovery of filter element can be used. The recovery wind is soft, and the powder sprayed by the spray gun is partially absorbed by the workpiece, and the excess powder passes under the action of the fan. The cyclone barrel is recycled and transported to the sieving machine for recycling. The ultra-fine powder is absorbed by the filter element twice, and the powder is dropped by the electromagnetic pulse valve backflushing, and falls into the recovery tank for full recycling. The recycling rate is about 95%. The recycling method has the advantages of convenient color change, simple cleaning, and small floor space.     2, paint recycling equipment (commonly known as spray booth):           It consists of chamber body, water curtain plate, water pump pipeline, air suction device, purification device and electronic control. The water curtain spray booth uses the functions of the water curtain plate, the bottom scroll plate and the baffle plate to complete the filtering paint mist to achieve the effect of purifying the exhaust gas. During work, the air containing the paint mist is under the action of the gravitational force of the ventilator, and the water flowing out of the overflow tank forms the water surface of the water curtain and the pool directly in front of the water flow. When the paint mist hits the water curtain or the pool surface, it will be adsorbed by the water. The secondary impact of the scroll falls into the water and accumulates in the water tank. The paint mist that does not touch the water curtain enters the back of the spray booth from the lower part of the water curtain, is washed by the spray mist, and collects the paint mist twice. The paint mist collides with the water mist in the dehydration chamber to form a water droplet containing the paint mist, and falls into the lower portion of the dehydration chamber to be stored in the water tank, and the separated air is discharged to the outside by the fan. This part of the air belongs to the exhaust gas emission. It can be equipped with a purification tank or exhaust gas treatment equipment to treat the harmful substances such as benzene, toluene and xylene in the exhaust gas to the national secondary discharge standard of GB 16297-1996. ● Suspended conveyor equipment:     The suspended conveyor chain system is an important part of the coating line and is responsible for conveying the product to different process points for surface treatment. The conveyor is generally of overhead type, which can freely choose the hoisting route and effectively utilize the space. It is mainly composed of chain rails, brackets, turning and lifting rails, driving devices, tensioning adjustment devices and lubrication devices.The specific instructions are as follows:      1. Chain: The hanging conveyor line is moved by the chain in the track, and is combined with the chain by the spreader to take charge of the load. The structure is: there are vertical and horizontal rollers at each pitch, and the ball bearings for the longitudinal rollers that carry the load are used to reduce the frictional resistance during the migration.      2. Track: A unit that guides the chain to move up, down, left, and right, and is formed by steel plate.      3. Brackets: Most of the track brackets are divided into two types: one is light load reuse, which is the method of hanging from the floor of the floor, and the other is heavy load reuse, that is, the pillar support method, both methods use angle steel and Made of channel steel.      4. Turning and lowering track: The hanging conveying line is also called the universal chain conveyor. Therefore, the turning and lifting of the direction must be coordinated by the horizontal elbow and the lifting elbow.      5. Drive device: It is a crawler drive type, which is composed of a three-phase AC motor, a worm gear reducer, a transmission chain tension adjuster, a drive sprocket, a shear pin and a drive track chain.      6. Tension adjustment device: The hammer is naturally hammered when the chain is under load, and the pitch is extended during the wear and tear. For continuous smooth operation, the tension adjustment device is required to absorb the elongation of the chain. The device generally has a heavy hammer type and a screw type. And the spring type three ways, the rails can be mounted on the movable frame by sliding the rails, and the hammers, the screws, the springs and the like are slipped to achieve the purpose of adjusting the chain tightness.      7. Lubrication device: The frictional force of the chain will increase for a long time. In order to avoid the chain jam caused by excessive resistance, it is necessary to set up the fueling mechanism. It can be equipped with automatic oil dispenser to spray high temperature chain oil to ensure the chain is in the chain. Working in a good lubrication state.
