Description

Technical Field

[0001] The utility model relates to the field of aluminum foil hot pressing equipment, in particular to a medicinal cold-formed composite aluminum foil hot pressing device. Background Art

[0002] An aluminum foil hot press is a machine that processes aluminum foil using heat pressing technology. It is primarily used to tightly bond aluminum foil with other materials (such as plastics and paper) through heat pressing to form the desired composite material. Aluminum foil hot presses are widely used in a variety of fields, including packaging, food, and medicine.

[0003] The lower die of existing hot presses for cold-formed medicinal aluminum foil is reusable. Repeated contact with the heated upper die causes the temperature to rise, causing deformation of the plastic substrate and hindering product quality control. Furthermore, manual removal of the pressed product from the lower die is required, resulting in low work efficiency. Therefore, those skilled in the art have developed a hot press device for cold-formed medicinal composite aluminum foil to address the issues raised in the background art. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In the utility model, the feeding stepper motor drives the feeding tray to rotate rhythmically by 90 degrees, and the four lower molds are circulated to the bottom of the aluminum foil feeder in turn. The downward electric push rod pushes the heated upper mold downward to slide with the upper mold embossing groove, and hot presses the aluminum foil at the aluminum foil channel position onto the plastic substrate installed on the lower mold to complete the packaging of the plastic substrate. The four lower molds work in turn, which is convenient for loading the lower mold and improving work efficiency. The working interval of the same lower mold is increased so that it can cool naturally to prevent affecting product quality.

[0014] 2. In the utility model, a unloading station is set on the workbench. When the lower mold after pressing is rotated to the unloading station, within the same working rhythm, the unloading stepping motor first performs a 180° flip, so that the working surface of the lower mold turns downward. Under the action of gravity, the unloading top plate inside the lower mold is slidably connected with the top plate slide groove. The unloading ejector pin extends from the bottom of the capsule sink to push the plastic substrate away from the lower mold. The plastic substrate is unloaded with its own weight. The processed plastic substrate falls into the collecting box. After that, the lower mold is flipped 180° again to make the working surface of the lower mold turn upward again. When the feeding tray rotates 90° again to leave the unloading station, the empty lower mold is loaded. The automatic unloading is convenient to use, reduces manual operation and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
