Problems solved by technology

[0002] The existing double-station bottle blowing machine is mainly composed of an extruder and two independent mold bases. The mold base is provided with a mold. Mold → cutting material → lowering the mold frame → air blowing needle tube → blowing air → deflation → mold opening → blowing air needle tube back → on the mold frame, and continuously cycle the above procedures. When the double mold frame works, there are the following defects: due to The working procedures of the two mold bases are carried out at the same time. During the operation, there will be inconsistencies in the actions, resulting in the different lengths of the material tubes when receiving materials and making waste products. What's more, the longer the working time, the more movement between the two mold bases. The greater the error is; especially the large-volume double-station blow molding machine, such as a 30-liter double-station blow molding machine, cannot overcome the 2000kg mold base, and the inertia when moving is nearly ten tons and the repeat positioning accuracy is difficult. Process requirements to ensure independent forming of each station

Embodiment Construction

[0010] As shown in Figure 1, a blow molding control method of a double-station automatic bottle blowing machine, the blow molding machine is mainly composed of an extruder and two independent mold frames, the mold frame is provided with a mold, and the bottle blowing machine The working procedure of mold base 1 is from upper mold base 101→mold closing 102→material cutting 103→under mold base 104→air blowing needle 105→air blowing 106→air release 107→mold opening 108→retracting blowing needle 109, The mold base 1 continuously circulates the above procedures; the working procedure of the mold base 2 of the bottle blowing machine is from 201 on the mold base → clamping mold 202 → material cutting 203 → under the mold base 204 → air blowing needle 205 → blowing air 206 → deflation 207 →Mould opening 208→Blow-back needle 209, the mold base 2 continuously circulates the above-mentioned program. After the above-mentioned cycle of each mold base is completed, it sends a signal to the c...

Abstract

A method for controlling the automatic bottle blower with dual working positions is disclosed. Said automatic bottle blower is composed of an extruder and two individual mould holders with moulds (one for one). Said two mould holders are working consistently according to such steps as lifting up mould holder, closing mould, cutting material, lowering down mould holder, inserting tube, blowing, releasing air, opening mould, and withdrawing tube up. Said steps are controlled by computer.
