Rotary blank-feeding linear automatic bottle blowing machine

Abstract

The invention discloses a rotary blank-feeding linear automatic bottle blowing machine, which comprises a heater and a pull blowing machine, wherein the heater is provided with a blank-feeding mechanism; the blank-feeding mechanism is provided with a blank introducing frame, a single slipway discharger and a conveyer; a blank taking mechanism, a relay station and a blank conveying mechanism are arranged between the heater and the pull blowing machine; the heater comprises a follower fixture, a revolution transmission, an autorotation transmission, a heating lamp box, a conveying guide rail and an air extracting device; and the pull blowing machine comprises a die closing mechanism, a seal stretcher and a bottle taking mechanism. The bottle blowing machine is characterized in that: the blank taking mechanism comprises a servo motor, a blank taking electric cylinder, a lifting cylinder, a blank taking manipulator, a blank taking linear guide rail and an advancing and retreating cylinder; the relay station comprises a strut head, a chain, a switching cylinder, an upgrade cylinder and a relay station linear guide rail; and the seal stretcher comprises a seal support seat, a sliding seat, a pedestal, a synchronous belt, a stretching rod, sliding angle iron, a synchronous belt pulley, a seal motor, a seal lifting cylinder and a seal linear guide rail.

Description

technical field [0001] The invention relates to a bottle blowing machine, in particular to a rotary type preform-feeding linear automatic bottle blowing machine, which belongs to the field of plastic machinery. Background technique [0002] The plastic blow molding machine is used to produce plastic hollow containers, such as mineral water bottles, oil bottles, etc. First, the plastic raw materials are injected into preforms, and then the preforms are sent to the heater for heating, and then the heated preforms are sent to the stretch blow molding machine. In-machine stretch blow molding. Existing equipment heaters and stretch-blow machines share the same chain running track, which is called (full) automatic linear blow molding machine, mainly including preform feeding mechanism, preform heating and conveying mechanism, stretch blowing mechanism and bottle fetching mechanism, etc. Its disadvantages are as follows: 1. The embryo loading mechanism generally adopts the grippin...

AI Technical Summary

Problems solved by technology

Its disadvantages are as follows: 1. The embryo loading mechanism generally adopts the gripping structure of the manipulator. The manipulator needs to complete movements such as forward and backward displacement, up and down lifting, and rotation. First, the speed is slow and the production efficiency is low; Second, when the preform is heated, it is directly added to the stretch blowing mechanism for stretch blow molding. Arranged at intervals, the overall volume of the heater is large, the heat utilization rate is low, and the energy loss is large; 3. When the preform enters the stretch-blow mechanism for stretch blow molding, each preform must correspond to a sealing cylinder, which requires a large cost investment. And the sealing cylinder cannot move, and sometimes it cannot be closely matched with the preform mouth, causing air leakage and affecting the quality of the formed bottle
