When the zinc plating pretreatment device is used, the zinc plating pretreatment device is divided into two flow lines according to different galvanized products, namely pretreatment is carried out from a first treatment line and a second treatment line, and if pretreatment is carried out through the first treatment line, the flow lines are as follows: manual feeding → feeding of a magnetic feeding machine 1 → degreasing of a through type ultrasonic degreasing machine 2 → feeding of an automatic weighing feeding machine 3 → first skip type processor 64 → conveying of a rubber belt conveyor 7 → drying of a dryer 8 → lifting of an inclined lifter 9 → uniform feeding of a vibrating feeder 10 → quantitative feeding of a quantitative scale 11 → quantitative feeding of a hot galvanizing equipment hot dip zinc → air cooling of an air cooling conveyor 18 → water cooling of a water cooling conveyor 19 → manual inspection of a buffer inspection conveyor → drying of a conveyor 21 drying of a workpiece → packaging of an automatic weighing packaging conveyor finished product;

if the processing is carried out through the second processing line, the flow line is as follows: manual feeding → shot blasting of a shot blasting machine → manual transfer to a material lifter 5 for lifting → a second tipping bucket type processor → a rubber belt conveyor 7 for conveying, and then the equipment and the process are the same as the first processing line.

The working principle of each independent device in the pretreatment device on the production line is as follows:

the working principle of the magnetic feeding machine 1 is as follows: the manual work is with in the leading-in vibration hopper of work piece, vibration hopper bottom is equipped with vibrating motor, vibrating motor intermittent type vibration, carry the work piece on the stainless steel meshbelt, stainless steel meshbelt bottom is that drive chain drives the magnetic stripe that is equipped with magnet and moves together, the magnetic stripe drives the stainless steel meshbelt through frictional force and upwards carries together, magnet transmits the guipure surface adsorption work piece with magnetism simultaneously, thereby it promotes the transport feed together to drive the work piece, the benefit can be with accumulational work piece flat spread out, and even carry on the ultrasonic cleaner guipure, realize even cloth, and speed is adjustable, select suitable speed according to different work pieces.

Through type ultrasonic degreasing machine 2 theory of operation utilizes the strong mechanical vibration of ultrasonic cavitation osmotic force to strike the workpiece surface and combine cleaner decontamination to make workpiece surface clean, the course of operation is that front end magnetism material loading machine 1 will treat that abluent work piece is sent into the guipure on, pass through the guipure conveying and get into the cleaning machine host computer, through each washing station with the work piece, send the work piece into next process at last, the benefit is that the ultrasonic wave uses with removing the finish jointly, deoiling, it is more thorough to remove the dirt, help improving the zinc-plating quality of product.

The working principle of the automatic weighing and feeding machine 3 is as follows: automatic material loading machine 3 weighs fill front end and is carried the material loading by through type ultrasonic degreasing machine 2, the limit material is weighed fill limit and is weighed, when weight reachs the settlement weight value, front end ultrasonic degreasing machine stop operation, the cylinder action, promote the upset frame and upwards revolute the axle upset, it does the upset action together to drive the interior weighing fill of frame simultaneously, when the upset reaches certain angle, the work piece slides down and gets into next process from weighing the fill, the back is accomplished in the material pouring, the cylinder withdrawal, it will weigh the fill and place on the weighing platform to drive the whereabouts of fighting of weighing simultaneously, front end ultrasonic degreasing machine starts the operation material loading, reciprocal with this circulation, the benefit is automatic processing, automatic weighing, the stirring, do not need artifical the participation, degree of automation is high, high use efficiency.

The operating principle of the first skip handler 64 and the second skip handler: when the front-end feeding machine is ready to turn over for feeding, the feeding doors of the first skip bucket type processor 64 and the second skip bucket type processor are opened to wait for feeding, and after the feeding is finished, the feeding doors are closed; the feeding is firstly poured into a pretreatment pickling bucket 41 for soaking and pickling, when the set time is up, the pickling bucket 41 turns over a cylinder to act, a workpiece is turned over and guided into the pickling bucket 41, and so on, then the workpiece is turned over and guided into a water washing bucket 42 and an auxiliary bucket 43, when the auxiliary bucket 43 is soaked for the set time, a rear-end blanking door is opened, the auxiliary bucket 43 turns over the cylinder to act to convey the workpiece into a rubber belt conveyor 7 in the next process, and after the pouring is finished, the auxiliary bucket 43 is turned back, and the blanking door is closed. Pickling, washing, help and plate all adopt the tipping bucket mode to realize, and the benefit is that tipping bucket formula pretreatment can make the pickling more abundant, speed is piecemeal, simple structure, and equipment fault rate is low, links up well with front and back equipment, easily realizes the automation, does not need manual intervention to the tipping bucket adopts the PP material, acidproof, corrosion-resistant, more durable.

The difference between the first skip type processing machine 64 and the second skip type processing machine is that the number of the pickling buckets 41 of the first skip type processing machine 64 is large, for example, the number of the pickling buckets 41 of the first skip type processing machine 64 is 6, and the number of the pickling buckets 41 of the second skip type processing machine is two.

The working principle of the material hoister 5 is as follows: the manual work is transported the fill and is placed on 5 unpowered gyro wheels of material lifting machine with throwing ball back work piece, and the manual work will be transported the fill and push the upset basket in, and the manual work starts the upset button, and gear motor starts, through sprocket chain drive, drives the upset basket and upwards promotes, and simultaneously, the upset basket drives and transports the fill and promote together, and upset basket both sides are fixed with two leading wheels respectively, and two leading wheels walk along two guide rails respectively, through changing one of them guide rail route, realize the upset of upset basket and expect. After the material has been poured, gear motor reverses, and with turnover basket and transport fill conveying return to the original position, the manual work is taken out idle running fortune fill, waits for next fortune fill material loading.

The working principle of each device in the first conveying mechanism on the production line is as follows:

the gear motor in the rubber belt conveyor 7 drives the driving roller to rotate through chain wheel and chain transmission, the driving roller drives the rubber belt to run through friction force, so that a workpiece on the surface is driven to be conveyed forwards into the dryer 8, the driving roller is dragged to move in the dryer 8 through the transmission device, circulating hot air flows through the materials, water vapor is discharged from the moisture discharging hole, and the workpiece is dried and enters the inclined elevator 9 to be used for lifting the workpiece after the drying is finished.
