Drying equipment is needed in the production process to dry the semi-finished wet impact-resistant gypsum board to complete the molding process.

[0003] The utility model with the existing patent application number: 202022117172.0 provides a drying device for the production of gypsum board, including a shell, and the inner walls on both sides of the shell are fixedly installed with heat insulation boards, and the bottom of the shell is fixed with a heat dissipation plate, and the surface of the heat dissipation plate is evenly spaced with heat dissipation holes. When in use, the controller starts the fan, and during the rotation of the fan, the wind begins to be transmitted upward, and after passing through the electric heating wire that is powered on and heated, it is blown out from the air outlet and becomes hot air to dry the gypsum board.

[0004] However, since the hot air can only act on one surface of the gypsum board, the gypsum board cannot be dried quickly, resulting in a reduced drying effect of the gypsum board. Summary of the invention

[0005] In order to improve the drying efficiency of gypsum boards, the present application provides a drying device for producing impact-resistant paper-faced gypsum boards.

[0006] The present application provides a drying device for producing impact-resistant gypsum board, which adopts the following technical solution: A drying device for producing impact-resistant gypsum board, comprising: A drying furnace has a feed port on the side wall; An installation component is arranged in the drying oven and is used to install the gypsum board; The drying component includes a heating element, a driving part and a heat transfer part. The heating element is fixed in the drying furnace and is used to heat the air in the furnace. The driving part and the heat transfer part are both arranged on the drying furnace.

[0007] By adopting the above technical solution, the gypsum board is placed into the drying furnace through the feed port, the gypsum board is installed and fixed by the installation assembly, and then the heating element heats the air in the furnace to provide the required heat energy for drying the gypsum board; After the gypsum board is installed, the driving part drives the heat transfer part to blow and stir the hot air flow in the drying furnace, so that the hot air can be evenly distributed and can evenly wrap the gypsum board, thereby ensuring that the gypsum board is dried more evenly and quickly, thereby improving the drying efficiency of the gypsum board; In addition, the efficient drying process also helps to reduce the moisture content inside the gypsum board, improving its impact resistance and durability.

[0008] Optionally, the driving unit includes: A motor, fixed on the top of the drying furnace; The connecting shaft is coaxially connected to the output shaft of the motor and is located in the drying furnace.

This flow helps to eliminate the temperature gradient in the drying furnace, so that the gypsum board is heated more evenly during the drying process; In addition, the rotation of the coordinated fan not only promotes the flow of hot air, but also enhances the heat exchange efficiency between the hot air and the gypsum board, allowing the hot air to penetrate into the interior of the gypsum board more effectively, thereby accelerating the evaporation of moisture and further improving the drying efficiency.

[0012] Optionally, the heat transfer parts are provided in a plurality of groups, and the plurality of groups of heat transfer parts are arranged around the axial direction of the connecting shaft.

[0013] By adopting the above technical solution, the simultaneous operation of multiple groups of heat transfer parts can produce stronger airflow disturbance and wider airflow coverage, which ensures that the hot air in the drying furnace is more evenly distributed, further reducing the temperature gradient, thereby providing a more stable drying environment for the gypsum board.

[0014] Optionally, the heating element is located at the bottom of the drying oven, and the drying assembly further includes a heat dissipation portion, which includes: An intermediate gear, coaxially connected to the connecting shaft and located at a side away from the motor; A plurality of driving gears, all meshing with the intermediate gear and all rotatably connected with the drying furnace; A plurality of driving fans correspond one to one with the plurality of driving gears, and the driving fans are coaxially fixedly connected with the driving gears.

[0015] By adopting the above technical solution, the heating element heats the air in the oven, the connecting shaft drives the intermediate gear to rotate, the intermediate gear drives multiple driving gears to rotate simultaneously, and each driving gear drives its own driving fan to rotate, so as to transport the hot air from the bottom to the top, thereby strengthening the heat convection at the bottom of the drying oven, thereby accelerating the flow of hot air in the drying oven, promoting the heat exchange between the heat and the gypsum board, and thus easily improving the drying efficiency.

[0016] Optionally, the installation component includes: A main shaft, coaxially connected to the connecting shaft and rotatably connected to the drying furnace; An upper clamping bar, one end of which is fixedly connected to the main shaft; A lower clamping bar, located below the upper clamping bar, and one end of which is fixedly connected to the main shaft, and the upper clamping bar is arranged parallel to the lower clamping bar; Wherein, a placement groove is provided on one side of the upper clamping strip and the lower clamping strip which are close to each other, and the two placement grooves are used to clamp the gypsum board.

[0017] By adopting the above technical solution, the gypsum board is inserted into the two placement grooves through the feed port to complete the clamping. Then, the connecting shaft drives the main shaft to rotate, the main shaft drives the upper clamping bar and the lower clamping bar to rotate, and the upper clamping bar and the lower clamping bar drive the gypsum board to rotate, thereby increasing the contact area between the gypsum board and the hot air flow, thereby improving the drying quality and efficiency, and then easily reducing production costs and labor intensity.

[0019] By adopting the above technical solution, when the gypsum board is placed in the placement groove, the extrusion block slides into the retreat groove under the pressure of the gypsum board, and at the same time the extrusion spring is compressed, and the extrusion spring accumulates elastic force. As the gypsum board completely enters the placement groove, the extrusion spring pushes the extrusion block to move toward the gypsum board until the ball is in close contact with both sides of the gypsum board, thereby facilitating automatic adaptation and stable clamping; In addition, due to the rolling friction between the ball and the gypsum board, compared with the sliding friction between the gypsum board and the extrusion block, the gypsum board is easier to enter the placement groove, and the damage to the gypsum board is also less; Furthermore, since the extrusion block has a certain elasticity under the action of the extrusion spring, it can adapt to gypsum boards of different thicknesses. No matter how the thickness of the gypsum board changes, the extrusion block can tightly clamp both sides of the gypsum board under the push of the spring to ensure the stability of the clamping, thereby improving the automatic adaptability of the device.

[0021] By adopting the above technical solution, when the main shaft drives the upper clamping bar and the lower clamping bar to rotate, and the upper clamping bar and the lower clamping bar drive the gypsum board to rotate, the hot air flow enters the drainage tube through the windward hole, and the hot air flow drives the guide fan to rotate, and the guide fan guides the hot air flow into the drainage hole. Since the drainage hole is connected with the ventilation hole, the hot air flow blows to the end of the gypsum board through the ventilation hole, forming a targeted wind flow, so that the two clamping ends of the gypsum board can be dried at the same time, so that the heat can be transferred to the inside of the gypsum board more quickly, thereby improving the drying efficiency.

[0022] Optionally, the installation components are provided in multiple groups, and the multiple groups of the installation components are arranged around the axial direction of the main shaft.
