Description

Technical Field

[0001] The utility model relates to the technical field of blanking devices, and more specifically, to a blanking device of a vacuum forming machine for producing blister trays. Background Art

[0002] Blister trays, also known as plastic inner trays, are plastic trays made by forming hard plastic sheets into specific grooves using a blister process. They offer numerous advantages and are widely used in numerous industries. They are commonly used for product packaging, transportation, and storage, helping to improve logistics efficiency and ensure product quality. With the continuous advancement of technology and changes in market demand, blister trays are also undergoing continuous development and innovation, with their performance and functionality constantly improving. Vacuum forming machines play a vital role in the production of blister trays. These machines soften the plastic sheet by heating it and then use vacuum suction to fit it into a mold. The continuous development and advancement of production technology has placed higher demands on the unloading device of vacuum forming machines. The existing unloading method typically requires an operator to directly remove the formed tray from the mold using a unloading device. This method is not only inefficient, making large-scale production more laborious, but also prone to misoperation and damage to the tray, affecting overall production efficiency and quality stability. To address the shortcomings of existing technologies, we have proposed a unloading device for vacuum forming machines used in blister tray production. Utility Model Content
