Technical Field

[0001] The invention relates to the technical field of plate hot pressing, in particular to plate processing hot pressing equipment. Background Art

[0002] Sheet hot pressing is a process that compresses the sheet to a predetermined thickness under heating and pressure, and promotes the curing of the adhesive to form a sheet with certain mechanical strength and water resistance. During the hot pressing process, heating causes the temperature of the adhesive layer to rise to the curing temperature, while pressure causes the cells in the sheet to come into close contact to achieve the required thickness and density. This process is widely used in many fields such as artificial board manufacturing and plastic processing.

[0003] After searching, a Chinese patent (publication number: CN112792934B) discloses a multi-layer board hot pressing forming equipment, which includes a base, a mounting frame, a clamping and fixing mechanism, and a rolling pressing mechanism, which is used to solve the problem that the traditional hot pressing forming device fails to adjust the alignment when the blank is pressed during the hot pressing forming process, and is prone to deviation, resulting in the edge of the formed fiber board failing to be hot pressed and needs to be trimmed before it can be put on the market. The existing hot pressing device heats the blank on one side, resulting in poor hot pressing effect, resulting in serious quality problems in the produced fiber board, and when the blank is pressurized during the hot pressing process, there is a problem of uneven pressurization of the board.

[0004] In the prior art, when hot pressing a plate, it is necessary to conveniently place the plate to be hot pressed into the hot pressing equipment, and during processing, it is necessary to avoid the edge of the plate raw material from cracking due to uneven pressure or insufficient adhesion between the raw materials. Therefore, the present invention proposes a plate processing hot pressing equipment. Summary of the invention

[0005] The object of the present invention is to provide a hot pressing device for processing a plate.

[0006] The technical problem solved by the present invention is: how to facilitate and quickly place the plates into the hot pressing equipment, and how to improve the pressurization quality between the plates during processing.

[0007] The present invention can be implemented by the following technical scheme: a plate processing hot pressing device, comprising a frame and a plurality of pressurizing plates, a pressurizing assembly is installed on the top of the frame, and a plurality of stroke assemblies are installed on the top of the frame on one side of the pressurizing assembly, the stroke assembly comprises a cylinder mechanism, the output end of the cylinder mechanism is arranged downward, and an electromagnetic assembly is installed;

[0009] When the sheet to be hot-pressed is placed between the pressure plates, each travel assembly is connected to the topmost pressure plate and lifts it upward until each layer of pressure plates is unfolded through each connection assembly and cooperates with the bottommost pressure plate to keep each layer of pressure plates in a fixed state;

[0010] The front side of the frame is movably connected with a rotating plate, and the inside of the frame is provided with side support frames on the non-front side of each layer of the pressurizing plate through a driving track. After each driving track is started, a corresponding set of side support frames is moved to one side of each layer of the pressurizing plate, and each layer of the pressurizing plate is constrained from the side, so as to avoid the problem of deviation of the moving track of each layer of the pressurizing plate during subsequent hot pressing.

[0011] Each of the side support frames and the rotating plate is provided with a multi-layer glue repair component on the side facing the pressure plate, and the height of each layer of the glue repair component corresponds to the height of each layer of the pressure plate when it is unfolded, that is, each layer of the glue repair component of each side support frame and the rotating plate is respectively adapted to the height of the upper surface of the remaining pressure plates except the topmost pressure plate.

[0012] A further technical improvement of the present invention is that: a side heating assembly is installed on the front side of each of the pressure plates, a lifting assembly is installed on the inner bottom end of the frame, and the lifting assembly is arranged on the vertical lower side of each of the side heating assemblies;

[0022] An elastic frame is installed at the output end of the stroke unit, and a glue spraying unit is installed on one side of the elastic frame;

[0023] After the stroke unit is started, it drives the elastic frame and the glue spraying unit to move toward the side corresponding to the plate, and after the horizontal drive unit is started, it drives the glue spraying unit to move along the side corresponding to the pressure plate. When the side of the pressure plate is uneven, the glue spraying unit changes its path through the elastic frame.

[0025] The upper and lower ends of the connecting chain and the elastic rod are respectively connected to adjacent pressure plates;

[0026] When each layer of pressure plates is unfolded, the connecting chain is used to maintain the connection between adjacent pressure plates and bear the force;

[0027] The elastic rod is kept in an arched shape, and the arched direction of the elastic rod is toward the connecting chain;

[0028] After each layer of pressure plates descends, the elastic rod bends in the direction of the arch and supports the connecting chain to prevent the connecting chain from invading between the pressure plates and affecting the hot pressing.

[0032] The present invention can heat press a plurality of plates at the same time by setting a multi-layer press plate, and when placing the plates, the side heating assembly on the side of the press plate facing the staff does not block the press plate, which is convenient for the staff to place the plates on the press plate, and during the hot pressing, the side heating assembly can block the side of the press plate, thereby improving the efficiency of the hot pressing;

[0033] In addition, during hot pressing, each side support frame cooperates with the rotating plate to cover each layer of pressure plates from the side. While keeping the downward pressure of each layer of pressure plates stable, the side of the plate is glued to improve the quality of the plate during hot pressing. During hot pressing, the glue filling component can be rotated to the side facing away from the plate. While protecting the glue filling component, the plate can be heated from the side.
