Description

Bottle blank heating and spacing integrated structure of bottle blowing machine

Technical Field

The invention relates to a bottle blank heating and spacing integrated structure of a bottle blowing machine.

Background

In recent years, the beverage industry in China is rapidly developed, which drives the rapid development of beverage machines, and a bottle blowing machine is a common machine for producing beverage bottles in beverage machine factories. The heating energy consumption of the bottle blowing machine is the largest part of the whole production line, the traditional bottle blowing machine is not provided with a variable-pitch device, and the space between the bottle blank seats and the space between the bottle cavities of the mold are equidistant, so that the heat energy utilization rate of the heating lamp tube is greatly reduced. The variable-pitch mechanism for the bottle blanks of the bottle blowing machine can achieve the purpose that the distance between the bottle blanks and the bottle blank is smaller than the distance between the mold cavities of the mold when the bottle blanks are heated, in a lamp tube area with the same length, the heating quantity of the bottle blanks is increased by multiple times compared with the traditional variable-pitch mechanism for the bottle blanks without the bottle blowing machine, the utilization rate of heat energy of the lamp tubes is greatly improved, and the purpose of energy conservation is achieved.

The bottle blank variable-pitch mechanism of the existing bottle blowing machine is arranged behind a bottle blank heating mechanism, a position in front of a blow molding die is composed of a plurality of push rods with guide heads, adjacent push rods are connected through chains with set lengths, a push rod at the tail end of the downstream is connected with a cylinder piston rod, a cylinder drives a push rod at the tail end during pitch change, the chain is pulled by the push rod at the tail end, after the chain is straightened, the next push rod is pulled by the chain, the chain is pushed by the next push rod, after the chain is straightened, the next push rod is pulled by the chain, and the like. This kind of structure needs the very big cylinder of stroke just can accomplish above-mentioned action, and a plurality of bottle base variable pitch is asynchronous simultaneously, has the time difference each other, and first bottle base is the biggest with last bottle base time difference, can lead to the adhesion between the bottle base that has been heated, and the motion is not smooth, leads to the rejection rate to rise. The bottle blank slides, and the guide head at the lower end of the push rod needs to move downwards to be inserted into the bottle blank opening, so that the bottle blank can be driven to slide on the guide rail to change the pitch, and the bottle blank needs to move upwards to be separated from the bottle blank opening after the pitch is changed. The up-and-down movement of the push rod is realized by driving the whole bottle blank variable-pitch mechanism of the bottle blowing machine to move up and down through the air cylinder, the action response is slow, and the efficiency is low.

An existing bottle blank spacing mechanism is shown in application number 2016201857149 and is realized by matching positive and negative rotation of a screw with movable clamping jaws, as shown in fig. 1, the structure of the existing bottle blank spacing mechanism is complex, faults are easy to occur, and frequent maintenance is needed.
