Description

TECHNICAL FIELD

[0001] The application relates to a feeding platform on a dustproof blow molding packaging production line for high-precision valve castings. BACKGROUND

[0002] Blow molding is a molding process mainly used for plastic products, which makes plastic materials expand and form through heating and blowing. In the manufacturing process of high-precision valves, blow molding technology is used to manufacture some plastic parts, which are then combined with metal castings to form a high-precision valve assembly of composite materials. After blow molding, the plastic parts need to be transported to the packaging production line by a feeding platform.

[0003] According to the announcement No. CN111347653B, a feeding platform on a dustproof blow molding packaging production line for high-precision valve castings is disclosed, which comprises a platform main body, a receiving table fixedly installed at the front right of the platform main body, a conversion mechanism fixedly installed at the rear left of the top plane of the platform main body, a dustproof mechanism fixedly installed vertically to the right of the upper end of the conversion mechanism, a driving mechanism horizontally installed on the platform main body in front of the conversion mechanism, a pushing mechanism fixedly installed at the right end of the driving mechanism, a belt adjusting mechanism longitudinally installed in the middle of the dustproof mechanism, and a flow guide table fixedly installed at the rear right corner of the top plane of the platform main body.

[0004] The above technical solution provides an inclined material guiding groove at the upper end bending part of the receiving disc, which can facilitate the timely downward delivery of high-precision valve castings after blow molding. However, when feeding high-precision valve castings, the high-precision castings will slide in contact with the surface of the feeding platform, which may cause collisions between high-precision castings and scratches on the feeding platform during feeding, resulting in damage or scratches on the high-precision valve castings. Moreover, the dustproof effect is poor because dustproof is only performed during feeding. SUMMARY

The power provided by the bidirectional motor can drive the fan blade to rotate, so that the fan blade can draw air from the limiting frame. The drawn air can blow on the surface of the high-precision valve casting, thereby preventing dust from adhering to the surface of the high-precision valve casting. After the fan blade draws air from the limiting frame, there is a certain pressure in the inside of the limiting frame, so that air can enter from the air suction cover, thereby the air suction cover can suck the blown dust into the three-way pipe. The dust is guided by the three-way pipe and directly delivered into the limiting frame. The filter plate can block the dust, thereby preventing the dust from scattering randomly. When feeding the high-precision valve casting, the high-precision valve casting can be prevented from colliding with each other and being scratched by the feeding platform, and dust can be continuously prevented from the high-precision casting, so that the dust prevention effect is strong.
