Technical Field

The invention relates to the technical field of relevant equipment of circuit board grinding machines, in particular to a copper powder recovery device for a self-cleaning type board grinding machine.

Background

Can produce a large amount of copper powders at the circuit board scrubbing in-process, consequently often need be equipped with the shower and erode the built-in work subassembly of board grinding machine when scrubbing, the high temperature that produces when can reducing on the one hand to polish, on the other hand still can wash away the copper powder through high-pressure rivers.

In order to avoid waste caused by copper powder loss, in the prior art, copper powder is recycled by erecting a pipeline to guide the water flow containing the copper powder into a copper powder recycling machine, and the copper powder is mainly filtered out by a filter bag or a filter screen and other filter equipment. However, the copper powder is soaked in water for a long time and is very wet, so that the copper powder has high viscosity, the filtered copper powder is easy to be adhered to the filter bag in a large scale to cause the reduction of the filtering performance, the recovery efficiency of the copper powder is further influenced, and meanwhile, the filter bag or the filter screen is usually arranged inside the recovery machine and is difficult to clean. Accordingly, the application file provides a self-cleaning formula grinds trigger and uses copper powder recovery unit.

Disclosure of Invention

The invention aims to solve the defects in the prior art, and provides a copper powder recovery device for a self-cleaning type plate grinding machine.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a self-cleaning formula copper powder recovery unit for grinder, includes the base, the circular recess has been seted up to the lateral wall of base, it is connected with the pivot to rotate on the inner wall of circular recess, the welding has the frame of a plurality of irons system on the lateral wall of pivot, just the outer wall of frame closely laminates with the inner wall of circular recess, the embedded filter screen that is equipped with of frame, it is equipped with a plurality of permanent magnets that correspond with the frame to inlay on the circular recess inner wall, fixedly connected with arc on the lateral wall of frame, the aqua storage tank has been seted up to the lateral wall of base, just the intercommunication has the delivery port between aqua storage tank and the circular recess, outlet pipe, the inlet tube of fixedly connected with and circular recess, aqua storage tank intercommunication respectively on two relative lateral walls of base, the same discharge gate with the.

Preferably, the inner wall of the frame is provided with a sliding groove, a scraping plate is connected in the sliding groove in a sliding mode, and the scraping plate is elastically connected to the side wall of the rotating shaft through a spring.

Preferably, the inner top of the chute is fixedly connected with a telescopic airbag, a one-way air inlet pipe communicated with the telescopic airbag is embedded in the frame, a one-way air outlet channel communicated with the telescopic airbag is formed in the side wall of the scraping plate, and a plurality of air outlet holes communicated with the one-way air outlet channel are formed in the upper end of the scraping plate.

The invention has the following beneficial effects:

1. by arranging the iron frame, the permanent magnet and other components, when the copper powder filtered out of the filter screen reaches a certain mass, the gravity of the copper powder on the filter screen is greater than the magnetic force, the rotating shaft can be pushed to rotate clockwise by a certain angle, and the copper powder falls out of the discharge port under the action of the gravity, so that the copper powder is prevented from being accumulated on the filter screen to influence the filtering performance of the filter screen, and the recovery efficiency of the copper powder is greatly improved;

2. by arranging the scraper, the spring, the permanent magnet and other components, when the rotating shaft does not rotate, the scraper is attracted by the permanent magnet and is attached to the permanent magnet, when the rotating shaft rotates for a certain angle, the distance between the scraper and the permanent magnet is far and the magnetic force is small, and the spring can pull the scraper to move in the reverse direction of the rotating shaft, so that residual copper powder on the filter screen can be scraped, the adhesion amount of the copper powder on the filter screen is further reduced, and the filtering performance of the filter screen is improved again;

3. through setting up parts such as flexible gasbag, one-way intake pipe and one-way air outlet channel, can remove the in-process at the scraper blade, exhaust to the venthole to partly remain the copper powder on the filter screen and blow off, in order to keep the good filter effect of filter screen.
