Description

Technical Field

[0001] The utility model relates to the field of fire door production, in particular to a hot press for producing fire doors. Background Art

[0002] The hot press is one of the main equipment in the production process of fire doors. It is used to hot-press and glue the slabs after the glue is applied. At present, the production process of fire doors usually involves laying a layer of fire-resistant plywood first - applying glue - laying the fireproof board - applying glue to another plywood - covering it on the fireproof board, and then pressing the semi-finished fire door with glue. At present, when the fire door is glued, when pressure is applied to the fire door, the force on the fire door is uneven, resulting in uneven gluing strength at various parts of the fire door, which affects the quality of the fire door.

[0003] After searching, a hot press machine for producing fire doors disclosed in announcement number CN220297370U includes a fixed box, the four corners of the top surface of the fixed box are fixedly connected with sliding rods, a fixing mechanism is arranged inside the fixed box, a hot pressing mechanism is arranged above the fixed box, and a conveying mechanism is symmetrically arranged on the left and right sides of the fixed box.

[0004] The above-mentioned technical solution has certain beneficial effects during use, but in actual use, since the thickness of the fire door has different sizes, if the thickness of the fire door is thin, and the fixed plate moves to the bottom of the hot pressing plate, it will hinder the downward pressing stroke of the hot pressing plate, resulting in the inability to stably hot press the fire door. For this reason, we propose a hot press machine for the production of fire doors. Utility Model Content
