Plastic bottle blowing machine

Abstract

The invention is a plastic bottle blower, including blank lift device, blank burying device, heating device, blank transmission device and blow molding device, where the blank lift device is set with a blank box and linked with the blank burying device through lift belt, the inlet of heating device is linked with the outlet of the blank burying device and the outlet of heating device linked with the blank transmission device, and the blow molding device is under the blank transmission device, its character: the heating device includes thermal insulating heating tank, heating pipe and blank supporting board, where the heating pipe is placed in the thermal insulating heating tank, the blank supporting board is on the top of the thermal insulating heating tank and set with heat insulating cover on the top and fixed with blank sleeve holding bottle blank at the bottom. It adopts the thermal insulating heating tank to heat the bottle blank, not only saving energy source but making the bottle blank uniformly heated and easier to blow molding; the mouth of the bottle blank is upward during transmission, heating and blow molding; the cylinder or servo mechanism drives mechanical hand to complete grasping and transferring the bottle blank, realizing automation.

Description

Technical field: [0001] The invention relates to a plastic processing machine, which is a special equipment for plastic bottle blow molding. Background technique: [0002] At present, there are the following situations in China about the plastic bottle blowing machine. One is to heat the preform with a wax pool, and then manually transfer the preform to a semi-automatic blow molding machine for blowing; the other is to use a far-infrared tube to heat the preform, and then manually transfer it to a semi-automatic blow molding machine for blowing ; There is also a far-infrared tube to heat the preform, but it is to transfer the preform to the blowing station with a manipulator for blowing. The first and second types of blow molding machines are easy to burn fingers because they need to be operated manually. Even wearing gloves, it is difficult to avoid contamination of the bottle. If it is to make PP bottles for medical infusion, this situation is not allowed. The second and...

Problems solved by technology

One is to heat the preform with a wax pool, and then manually transfer the preform to a semi-automatic blow molding machine for blowing; the other is to use a far-infrared tube to heat the preform, and then manually transfer it to a semi-automatic blow molding machine for blowing ; There is also a far-infrared tube to heat the preform, but it uses a robot to transfer the preform to the blowing station for blowing

The first and second types of blow molding machines are easy to burn your fingers because they need to be operated manually. Even if you wear gloves, it is difficult to avoid pollution to the bottle. If it is to make PP bottles for medical infusion, this situation is not allowed.

The second and third types of blow molding machines use electricity to heat the preforms, and the energy consumption is relatively large

At the same time, the bottle mouth of the third type of blow molding machine is upside down when blowing, so compared with the first two types, it is more likely to produce waste products due to uneven wall thickness caused by improper billet standing.
