[0002] Cartons are the most widely used packaging products. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer are less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper. Cartons are generally used for packaging and transporting items.
[0003] During the production of cartons, a hot press is used to press the pulp raw materials into cardboard, which is convenient for the subsequent assembly of cartons. The existing hot press uses a hot pressing block to press the raw materials. Only one side of the raw materials is heated, which is prone to uneven temperature and increases the time of hot pressing.

[0011] Preferably, the positions of the feed trough and the hot pressing block correspond to each other, and the hot pressing block is pressed downwardly to fit inside the feed trough.
[0012] Preferably, sliding holes are provided on both sides of the top of the support block, and the two sliding holes pass through the bottom end of the support block. Sliding rods are slidably fitted in the two sliding holes, and the bottom ends of the two sliding rods extend out of the bottom end of the support block, and the protruding ends are connected to the top of the hot pressing block.
[0013] The beneficial technical effect of the utility model is that after the raw materials are input into the feed trough, they will accumulate on the lifting plate. The raw materials and the lifting plate can be squeezed down by the downward pressure of the hot pressing block. At the same time, the hot pressing block and the electric heating plate inside the lifting plate are started to heat the upper and lower surfaces of the raw materials at the same time, making the cardboard forming faster, and at the same time making the hot pressing temperature more uniform and consistent, thereby accelerating the hot pressing rate.
