Full-mechanical-pressure bottle cap forming machine

Abstract

The invention provides a full-mechanical-pressure bottle cap forming machine which comprises a rack, a bottle cap forming die and a drive mechanism for driving the bottle cap forming die to be opened and closed. The bottle cap forming die comprises upper die bodies and lower die bodies. The drive mechanism comprises a forming rod, a turning cam mechanism and a stabilizing device, wherein the forming rod is arranged on the rack in a vertical movement mode, the turning cam mechanism drives the forming rod to conduct vertical reciprocating movement, and the stabilizing device makes the forming rod to move downwards to reset. The forming rod comprises an upper section, a lower section and an elastic element, wherein the upper section and the lower section are connected in a coaxial mode, and the elastic element is connected between the upper segment and the lower segment in a compressed mode and makes the upper segment and the lower segment have a vertical separation trend. The lower dies are fixed to the upper end of the upper section of the forming rod, and the upper dies are arranged on the upper portion of the rack and correspond to the upper portions of the lower dies. According to the full-mechanical-pressure bottle cap forming machine, a mechanical structure is adopted to provide stable forming pressure, a hydraulic system is replaced, the structure of the bottle cap forming machine is greatly simplified, the bottle cap forming die opening/closing process is smooth in movement, the bottle cap forming pressure is easy to adjust, and it is guaranteed that the forming pressure is stable.

Description

technical field [0001] The invention relates to a bottle cap forming equipment, in particular to a full-mechanical pressure bottle cap forming machine which relies on a mechanical structure to provide forming pressure. Background technique [0002] With the development of economy and society, there are more and more commodity categories such as bottled mineral water, fruit juice drinks, milk drinks and functional drinks, and the consumption has also risen sharply. At present, bottle caps such as mineral water bottles and beverage bottles are mainly molded by bottle cap forming machines. Therefore, the demand for such bottle cap forming machines is also increasing. In the market, bottle cap forming machines are basically monopolized by SACMI Group, and the current bottle cap forming machines on the market are all provided by hydraulic systems. In addition, the structure of the bottle cap molding machine becomes complicated due to the addition of many hydraulic devices such a...

Problems solved by technology

In the market, bottle cap molding machines are basically monopolized by SACMI Group, and the current bottle cap molding machines on the market are all provided by hydraulic systems. In addition, the structure of the bottle cap molding machine becomes complicated due to the addition of many hydraulic devices such as oil cylinders, reversing valves and hydraulic pumps, which makes it difficult to adjust the pressure of the bottle cap forming and difficult to operate.
