Six-drop individual section bottle-making machine and pressing and blowing production technology thereof

Abstract

The invention discloses a six-drop individual section bottle-making machine and pressing and blowing production technology thereof, belongs to the field of bottle-making machines, in particular to a multi-drop bottle-making machine and bottle-making technology thereof. The bottle-making machine comprises a frame, a parison mold molding mechanism, a molding mold molding mechanism and a bottle poking mechanism, and is characterized in that: a molding device of the parison mold molding mechanism is an integral multi-cavity stamping device which comprises a driving cylinder, a combined cylinder, a punch, a piston push-pull plate and a piston, wherein the piston is connected with the piston push-pull plate; six punches are arranged at the upper end of the piston push-pull plate; mold switching devices of the parison mold molding mechanism and the molding mold molding mechanism adopt a parallel switching mode in a horizontal plane; the bottle poking mechanism is driven by two stepping motors; and the two stepping motors drive a rotating disc and bottle poking arms of the bottle poking mechanism through a synchronous belt. The technology comprises six steps of separating materials, producing parison, turning, molding, clamping bottles and poking the bottles. The bottle-making machine has the advantages of high bottle-making yield, good molding quality and capacity of manufacturing high-grade glass bottles in multiple specifications.

Description

technical field [0001] The invention belongs to the field of bottle making machines, and in particular relates to a multi-drop glass bottle making machine and a production process thereof. Background technique [0002] In the glass bottle production industry, the bottle making machine adopts multi-drop forming technology to increase the output of a single machine. After more than 40 years of development, the bottle-making industry has upgraded from single-drop bottle making to double-drop or triple-drop bottle making machines. It can produce bottles with two to three times the output on the premise of the same energy consumption of a single machine, so as to reduce Cost of production. However, the traditional bottle-making machine uses a simple molding mechanism, adopts vacuum suction bottle mouth, blows backwards to form the preform, and blows the old technology of the bottle body to form two or three drops of glass bottles at a time, but there are mechanical problems.

AI Technical Summary

Problems solved by technology

Both of these two molding methods have the following problems: relying solely on the blowing process to form the glass preform body, the glass frit in the mold due to unequal contact time and uneven force, resulting in the formation of "half waist" and "half waist" on the surface of the bottle body. The defect of "wavy stripes" seriously affects the appearance quality of the bottle, and it is impossible to produce high-grade glass bottles

The traditional bottle shifting mechanism is divided into two types: mechanical cam type and single motor plus horizontal cylinder, which can basically meet the bottle shifting requirements of single and double drop material bottle making machines. However, on multi-group multi-drop material bottle making machines, How to transfer a group of multiple bottles to the high-speed mesh belt smoothly and as a whole is a difficult problem

During the production process, bottles are often squeezed and inverted, which seriously affects the machine speed and qualification rate.

[0008] The double-motor bottle-pushing mechanism of the same kind in China adopts 220V AC, high-speed, small-torque imported stepping motor, plus two planetary reducers for transmission, and then drives the compound movement of the turntable and the bottle-pushing plate. This structure has the following defects : The first-level transmission is added, which makes the structure complex, the efficiency is reduced, there is no overload safety protection function, and the imported AC motor is used, the cost is high, and there are problems such as unsafe use.
