When the preform is out of the injection molding machine, the temperature is between 45 ° C and 55 ° C. Dropping directly onto the belt can cause a bruise between the preforms.

 
PET (polyester) beverage bottles have only been developed in China for more than ten years, and the history of hot-filled PET beverage bottles in China is shorter, only about 6 years, but the development momentum is fierce, more than most other Packaging container. As we all know, tea drinks, juice drinks, etc. are the focus of beverage development, most of which are made of PET hot-filled bottles, and the proportion has a growing trend. So what problems should pet bottle embryos pay attention to during the production process? Let's take a look at the Xin Nan pet bottle.

Initially, consumers were only concerned about the quality of the beverage itself, but now they are beginning to pay attention to the packaging of the beverage. The quality of the PET bottle depends on the quality of the Pet Bottle Preform supplied. The preform is divided into two types, one is a long rubber mouth and the other is a short rubber mouth. Domestic bottle embryo manufacturers use more short-mouthed preforms, while foreign countries use more long-term glue. The preform of the long rubber mouth is cut off by the glue mouth at the bottom, and the tension is evenly distributed during the blowing process, so that the quality of the bottle which is blown out is better, and the cut portion can be recycled, which is beneficial to save the raw material cost. In today's increasingly scarce petroleum resources, domestic manufacturers will be more inclined to the preforms of long rubber. The quality of the preform during production is controlled by the degree to which the preform is prevented from being scratched during transport. At present, most domestic manufacturers use belt conveyor for the delivery of preforms, which is an old method of conveying technology. The disadvantages of this delivery are as follows:

When the preform is out of the injection molding machine, the temperature is between 45 ° C and 55 ° C. Dropping directly onto the belt can cause a bruise between the preforms.

When the preform comes out of the injection molding machine, there may be a problem in the quality of the embryo injected into the cavity. It is difficult to determine which cavity of the cavity has a problem.

When the injection molding machine is injecting the preform, a cavity may form a cavity, which is arranged in a disorderly manner. If it is counted according to the number of injection molding chambers, the counting will be inaccurate.

Belt conveyor, the quality control of the preform is to be done manually. First, the quality is difficult to control, and secondly, too much contact with the person is likely to cause pollution.

Nowadays, in Japan, South Korea, and Taiwan, it is common to use a chain plate to transport preforms in a certain order. The production process is as follows:

The preform forming machine removes all the glue machine from the front end of the product. The front part conveys a bottle of mouth knot product machine. The final stage conveys a test machine and counts the packing device;

The advantages of this type of transport are as follows:

1. The robot removes the preform from the injection molding machine, and the position of each preform is numbered. The preform is taken out by the robot and is not directly dropped to avoid scratching. Since the position of each preform is numbered, when there is a problem with the injection molding machine, it is possible to accurately find out which cavity has a problem.

2. The preform is transported by clamping the neck of the bottle through the plate chain, so that the preforms are delivered in an orderly order. In this way, the preforms are evenly cooled and easy to count, and the counting error per 10,000 preforms is within ±5.

3. The entire production line is automated and equipped with fewer personnel.
