Description

Technical Field

[0001] The utility model relates to the technical field of toothpaste tube production, in particular to an air blowing device for toothpaste tube production. Background Art

[0002] A toothpaste tube is a tubular container for holding toothpaste, usually made of plastic. The design of the toothpaste tube is mainly to facilitate users to use toothpaste so that the toothpaste can be squeezed out evenly. The toothpaste tube usually has a rotatable lid. Users can open the lid to squeeze out the toothpaste, and then put the lid back on to keep the toothpaste fresh and hygienic. In the production process of toothpaste tubes, the most commonly used processing methods are extrusion, injection, blow molding, foaming and thermoforming, and blow molding is an important process for processing and forming toothpaste tubes, so a toothpaste tube production blowing device is required.

[0003] In the process of blow molding, the traditional toothpaste tube production blowing device needs to connect the air inlet pipe with its matching toothpaste tube head. When connecting, the air inlet pipe and the toothpaste can are usually fixed with a clamp to ensure that their positions are fixed and will not move due to the force during the blowing process. However, the clamp is usually fixed with bolts and nuts. This operation method is relatively cumbersome, which reduces the practicality of the device. In addition, the valve must be opened and closed manually every time the blow molding is performed, which is troublesome, time-consuming, and reduces work efficiency. Utility Model Content
