Description

Technical Field

[0001] The utility model relates to the technical field of blister box production, in particular to a blister box punching device. Background Technique

[0002] Broadly speaking, blister boxes refer to all blisters. Narrowly speaking, they are just a type of blister: made by thermoforming a sheet into a plastic box shape, with the lid connected to the container. They are mostly made of PS, and there are also those with the lid and bottom separated, and different materials can be selected. For example, Japanese fast food boxes have a black PS bottom and a transparent PET lid. Thermoforming is a common plastic processing technology that heats and softens a flat plastic sheet and forms it by vacuum adsorption on the surface of a mold and then cools. The thermoforming process is widely used in industries such as plastic packaging, lighting, and decoration. Blister boxes are box-shaped products made by thermoforming plastic sheets, and a punching device is required during the production process.

[0003] The current blister box punching devices usually punch holes manually, making it difficult to ensure the punching position and having the defect of low punching accuracy. And the punching devices with fixed positions often have the phenomenon of punching deviation, and they do not have the function of collecting dust and debris, which is easy to pollute the working environment. Therefore, we propose a blister box punching device. Content of the Utility Model
