Description

Technical Field

[0001] The utility model relates to an automatic embryo loading machine, in particular to an automatic embryo loading machine with a buffer slideway for bottle embryos, and belongs to the technical field of automatic embryo loading machines. Background Art

[0002] The preform is the prototype of the PET bottle before it is formed. It has thick wall and high transparency. It can be sealed with ordinary plastic bottle caps. In addition, it is unbreakable and can stand on the table. It can be used to replace test tubes in many ways. The preform is generally formed with a hot runner mold. There are two types of preforms during injection molding, one is a long gate and the other is a short gate. Domestic preform manufacturers use short gate preforms more, while foreign manufacturers use long gates more. The preform with a long rubber mouth has the gate at the bottom cut off, so that the tension is evenly distributed during the bottle blowing process, so that the quality of the blown bottle will be better. Domestic manufacturers will prefer preforms with long gates. The control of the quality of the preforms during the production process depends on the degree of control to avoid scratches during the transportation of the preforms.
