Integral loading and unloading bottle cap molding machine

Abstract

The invention relates to an integral loading cap discharge type bottle cap mould pressing forming machine. The integral loading cap discharge type bottle cap mould pressing forming machine comprises a main machine assembly, an upper mold, a lower mold, an oil cylinder assembly, a transmission mechanism, a rotary support, a loading cap discharge assembly, a discharge hole head, a discharge hole reversing mechanism and an extruding mechanism, wherein the oil cylinder assembly is driven by a hydraulic system, the loading cap discharge assembly comprises a material separating main shaft, the material separating main shaft is provided with a material separating plate, a scraper is mounted under the material separating plate, and is matched with the discharge hole reversing mechanism, a water separating and material blowing plate is mounted on the material separating plate, a cap separating impeller and a cap discharge baffle ring are mounted outside the water separating and material blowing plate, a material separating and air blowing hole A, a binder blowing hole B and a material return air blowing hole C are formed in the water separating and material blowing plate, a plurality of material falling holes are formed in the material separating plate, and drive the material separating plate to correspond to the material separating and air blowing hole A, the binder blowing hole B and the material return air blowing hole C through the material separating main shaft by virtue of the transmission mechanism, and a material return pipe and a material return box are arranged below a material scraping knife rest.

Description

technical field [0001] The invention relates to a bottle cap molding machine of an integral feeding and cap discharging type, which belongs to plastic bottle cap processing equipment. Background technique [0002] At present, the production of mineral water bottle caps, beverage bottle caps and oil bottle caps, etc., is mainly molded by a bottle cap molding machine. The oil cylinder assembly, the transmission mechanism, the slewing support, the material loading and unloading cover assembly, the head of the material outlet, the reversing mechanism of the material outlet and the extrusion mechanism are composed. The oil cylinder assembly is driven by the hydraulic system. The prior art feeding and capping assembly is mainly composed of a material distribution pan, a sub-cover impeller and a water-distributing blowing pan. A scraping mechanism is installed under the pan. The raw material falls into the lower mold of the mold, and the hydraulic system drives the oil cylinder as...

AI Technical Summary

Problems solved by technology

However, in actual production, the raw material sticks to the scraping mechanism and cannot fall off. When scraping the next time, the scraper is easy to be damaged, and the raw material falls outside and is wasted.

Sometimes when there are other problems such as uneven heating of raw materials or reduction of extruded materials, the quality of the pressed bottle caps is unqualified, resulting in scrapping, which also wastes raw materials and increases production costs.

Especially when the distribution disc rotates and rubs against the water distribution blowing disc, the noise is loud, the distribution disc is easy to wear, affects the rotation accuracy, and the feeding is unstable

On the other hand, the oil tank of the existing hydraulic system is directly connected to the rotary oil seal through the oil circuit, which has poor sealing performance and is prone to oil leakage, resulting in hydraulic instability and affecting molding
