Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of plastic bottle processing equipment, and in particular relates to a plastic bottle injection nozzle waste material removal device. Background Technology
[0002] Injection molded bottles refer to plastic bottles manufactured using injection molding and blow molding processes. In this process, the raw material is first injection molded into a tubular preform by an injection molding machine, and then stretched and blow-molded into shape by a blow molding machine using a blow molding die. During the injection molding production process, the preforms generally contain sprue residue, i.e., gate residue. The gate is usually located at the center of the bottom of the preform, so the sprue residue is naturally located at the gate placement position. Generally, the sprue residue needs to be removed before blow molding.
[0003] However, existing plastic bottle injection nozzle scrap removal equipment does not have a grinding and polishing function. After the plastic bottle injection nozzle scrap is removed, there are often problems such as burrs and unevenness at the cut. In order to make the plastic bottle meet the qualified quality standards and meet the needs of subsequent packaging and use, it is necessary to use additional grinding equipment to grind the cut. This not only increases the production process and makes the production process more complicated, but also increases the production cost by investing in additional grinding equipment.
[0004] To address this issue, we provide a plastic bottle injection nozzle residue removal device to solve the problems mentioned above. Utility Model Content
