Bottle blank seating device of bottle blowing machine and bottle blank seating method

Abstract

The invention discloses a bottle blank seating device of a bottle blowing machine and a bottle blank seating method. The bottle blank seating device comprises a track, multiple bottle blank seats arranged on the track at equal intervals, a clamping unit and a feeding unit. The clamping unit comprises a platform and first and second clamping arm units arranged on the platform. The first clamping arm unit at least comprises a first clamping arm and a second clamping arm which is arranged at one side of the first clamping arm and is isolated from the first clamping arm at a bottle blank seat interval, wherein the clamping arm number of the first clamping arm unit is equal to that of the second clamping arm unit. The second clamping arm unit at least comprises a third clamping arm which is arranged at the other side of the first clamping arm and is isolated from the first clamping arm at two bottle blank seat intervals, and a fourth clamping arm which is arranged at a side of the third clamping arm and is isolated from the third clamping arm at a bottle blank seat interval. The feeding unit comprises multiple bottle blanks. The clamping arms are arranged at intervals so that the clamping arms are not influenced mutually in transverse operation of clamping jaws of the clamping arms and thus the bottle blank seats can be arranged closely and the number of bottle blanks subjected to one-step heating is increased and bottle blowing efficiency is improved.

Description

technical field [0001] The invention relates to a bottle blowing machine, in particular to a bottle blank seating device and a bottle blank seating method of the bottle blowing machine. Background technique [0002] Blow molding machine is a kind of equipment used to form resin and other materials into containers such as plastic bottles after several processes. [0003] refer to figure 1 As shown, the existing bottle blowing machine generally has a circular plane track 11, and is provided with a plurality of continuous preform seats 12 on the track 11, and its working process is through a swing clamp arm 13 with multiple rotatable The preform 14 is clamped by the clamping unit, and the preform 14 is placed on the preform seat 12 step by step. The preform seat 12 carries the preform 14 through the heating device 15 (heating chamber) according to the loading direction, so that The preform 14 is evenly heated and softened so as to enter the mold (not shown in the figure) to b...

Problems solved by technology

[0004] However, when each clamping arm 13 clamps the preform 14 and places the preform 14 on each preform seat 12, the jaws 131 of each clamping arm 13 need to perform a lateral opening action, and in order to prevent each clamping arm 13 from The clamping jaws 131 collide with each other when they are opened laterally, so the configuration between the clamping arms 13 needs to have a specific distance. Relatively, the preform holders 12 on the track 11 also have the specific distance. This structural design will make The arrangement of the preform holders 12 on the track 11 is not tight enough, which limits the number of preforms 14 heated by the heating device 15 at one time, which in turn affects the speed of the entire process, resulting in a relatively reduced output and an impact on cost and time
