[0018] The present invention provides an auxiliary feeding device for an ABS plastic electroplating production line through improvement, which has the following improvements and advantages compared with the prior art:

[0019] First, the present invention can make the raw materials enter the dust removal box at a constant speed through the setting of the quantitative valve, so that the first flip plate can be flipped downward, and a storage mechanism is provided, which can drive the connecting rod and the piston block to move inside the piston seat, so that the air inside the piston seat can be transported to the inside of the nozzle through the connecting pipe, and the raw materials move downward in the dust removal box. When the raw materials fall to the position of the nozzle, the air transported to the inside of the nozzle will be ejected through the air jet port, and the raw materials will be blown onto the first filter screen by the air, and the dust on the raw materials will be blown away. Then the reset spring will drive the first flip plate, the connecting rod and the piston block to reset. At the same time, the outside world can be supplemented to the inside of the piston seat through the check valve. At this time, the dusted raw materials will fall into the inside of the discharge pipe for loading, and then the loading pipe will feed the inside of the dust removal box again, and this reciprocating process can achieve the effect of dust removal of the raw materials while loading.

[0020] Secondly, the present invention arranges the movable plate and the partition seat. When the raw material flips and falls from the first flip plate, it will first fall on the movable plate. Under the action of the impact force, the movable plate moves to the inside of the partition seat, and the raw material will be blocked by the partition seat first. At this time, the raw material will be evenly distributed on the movable plate. At the same time, the return spring is compressed and releases the elastic force, thereby driving the movable plate to move upward, so that the movable plate moves to the position where the raw material will not be blocked by the movable plate. The raw material will fall downward from the inclined surface of the movable plate to the position of the nozzle to be dusted, and the raw material falls evenly, thereby improving the dust removal effect.

[0021] Third: In the present invention, since the mesh number of the first filter is small, the first filter can block the raw material, and the air containing dust will push the second flip plate, and the second flip plate flips toward the inside of the filter box to allow air and dust to enter the inside of the filter box. Since the partition is inclined, the airflow will be guided upward by the partition. After the third flip plate is flipped, the raw material enters the upper part of the interior of the filter box. At this time, the second filter can filter the air containing dust, and the air is discharged from the inside of the filter box, and the dust will remain in the inside of the filter box and be collected, thereby achieving the effect of collecting dust.

[0022] Fourthly: In the present invention, the raw materials are stored on the partition plate, and the electric telescopic rod is started. The electric telescopic rod drives the sealing plate to move upward through the piston rod, and the sealing plate is moved out from the inside of the partition plate. At this time, the raw materials on the partition plate can fall to the lower part of the storage box, and then fall into the inside of the feeding pipe. At the same time, when the piston rod moves inside the movable groove, the air inside the movable groove will be sprayed out through the upper air groove and the lower air groove respectively, so that the raw materials will not be blocked inside the storage box, thereby improving the feeding effect.

When it falls to the position of the nozzle 36, the air transported to the inside of the nozzle 36 will be ejected through the air jet 361, and the raw material will be blown onto the first filter 38 by the air, and the dust on the raw material will be blown away. Then the reset spring 35 will drive the first flip plate 32, the connecting rod 341 and the piston block 342 to reset. At the same time, the outside can be replenished into the inside of the piston seat 34 through the check valve 371. At this time, the dust-removed raw material will fall into the inside of the discharge pipe 4 for loading, and then the loading pipe 2 will feed the inside of the dust removal box 3 again, and this reciprocating process will achieve the effect of removing dust from the raw material while loading.
