Technical Field

[0001] This utility model relates to the technical field of particleboard production equipment, specifically a multi-stage pressurization and temperature control system for the hot pressing section of particleboard. Background Technology

[0002] In the particleboard production process, the hot pressing stage is a crucial step that determines the quality of the board. Traditional hot presses typically use a single pressure and temperature mode, which is difficult to adapt to the process requirements of particleboard blanks with different thicknesses or densities, resulting in uneven internal structure, poor surface quality, or excessive energy consumption.

[0003] In addition, the pressure height adjustment accuracy of traditional equipment is insufficient, and dynamic adjustment cannot be achieved, which affects production efficiency and product qualification rate.

[0004] Therefore, there is an urgent need for a hot pressing system that can control pressure and temperature in stages to address the shortcomings mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage pressurization and temperature control system for the hot pressing section of particleboard, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-stage pressurization and temperature control system for a particleboard hot pressing section includes a particleboard hot press body. A steel belt drive device is installed through the particleboard hot press body to continuously carry the particleboard blank after the pre-pressing process through the hot pressing zone. The system is characterized by: a mounting body horizontally arranged at the top inner part of the particleboard hot press body; several sets of hot pressing mechanisms arranged sequentially on the bottom surface of the mounting body along the movement direction of the particleboard blank; different sets of hot pressing mechanisms are used for pressurization at different heights; the hot pressing mechanisms are connected to a main controller, which controls and adjusts the height and temperature of the hot pressing; each set of hot pressing mechanisms includes a heating plate at the bottom, and each heating plate is electrically connected to the main controller to control the temperature of the hot pressing.

[0010] Preferably, the height adjustment device includes a gearbox with through holes on the upper and lower end faces, a lifting drive gear rotatably connected in the middle of the gearbox, a motor mounted on the side of the gearbox via a gearbox, and the motor being driven to the lifting drive gear via the gearbox; the lifting drive gear has a threaded hole, and the surface of the telescopic rod of the hydraulic cylinder has a corresponding thread, which is threadedly connected to the lifting drive gear; the motor of each hot pressing mechanism is connected to the main controller, the left and right sides of the gearbox form semi-circular grooves, the bottom surface of the hydraulic cylinder forms a corresponding guide rod, and the guide rod and the semi-circular groove are slidably connected.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 As shown, this utility model is a multi-stage pressurization and temperature control system for the hot pressing section of particleboard. It is used to hot press the continuous particleboard blank after pre-pressing in the previous pre-pressing process. Different hot pressing sections require different hot pressing pressures and temperatures. Pressing the particleboard blank into place in one step with a single hot pressing pressure and temperature can easily damage the particleboard blank structure, resulting in poor final board quality. Therefore, continuous hot pressing with different hot pressing pressures and temperatures is required.

[0022] Specifically, such as Figure 1 As shown, the multi-stage pressurization and temperature control system of the particleboard hot pressing section includes a particleboard hot press body 1. A steel belt drive device 2 is installed inside the body 1 to carry the pre-pressed particleboard blanks continuously through the hot pressing zone. The hot pressing zone is as follows: Figure 1 The area covered by the steel belt drive device 2 of the main body 1 of the particleboard hot press shown is where the particleboard blank is as follows. Figure 1 The continuous particleboard blank 20 is shown. Further optimized, a preheating furnace 18 is provided at the front end of the steel belt drive device 2 to preheat the particleboard blank, thereby improving the subsequent hot pressing effect.

[0023] Specifically, a mounting body 3 is horizontally arranged at the top inner part of the particleboard hot press machine body 1. Five sets of hot pressing mechanisms 4 are sequentially installed on the bottom surface of the mounting body 3 along the movement direction of the particleboard blank. Each set of hot pressing mechanisms 4 includes a heating plate 6, the bottom edge of which is rounded to avoid scratching the surface of the board. Preferably, the heating plate 6 is fixed to the bottom of the fine-adjustment height device 9 through a connecting pipe 10. The fine-adjustment height device 9 is connected to the telescopic rod 8 of the hydraulic cylinder 7 through a threaded transmission to achieve precise height adjustment.

[0024] like Figure 2 and Figure 3 As shown, the fine-tuning height device 9 includes a gearbox 11, with a lifting drive gear 12 rotatably connected in the middle of the gearbox 11. A motor 14 is mounted on the side of the gearbox 11 via a gearbox 13. The motor 14 drives the lifting drive gear 12 to rotate via the gearbox 13, and the lifting drive gear 12 achieves fine-tuning of the height through threaded engagement with the telescopic rod 8. Further optimized, semi-circular grooves 15 are formed on the left and right sides of the gearbox 11, which are slidably connected to the guide rod 16 on the bottom surface of the hydraulic cylinder 7 to ensure the stability of the adjustment process. The motor 14 of each set of hot-pressing mechanisms 4 is connected to the main controller 5, which uniformly controls the pressurization height and temperature; more specifically, as... Figure 1 As shown, the hydraulic cylinder 7 is electrically connected to the main controller 5 via a regulating valve 19, and the extension and retraction of the hydraulic cylinder 7 are controlled by the main controller 5.

[0025] Specifically, such as Figure 1 As shown, an auxiliary heating plate 17 is also provided below the steel belt drive device 2 of the main body 1 of the particleboard hot press. The auxiliary heating plate 17 is electrically connected to the main controller 5 and is used to provide auxiliary heating to the particleboard blank from below, thereby further optimizing the hot pressing effect.

[0026] In use, the pre-pressed particleboard blank is preheated by the preheating furnace 18, and then continuously conveyed to the hot pressing zone by the steel belt drive device 2. Subsequently, the blank passes through five sets of hot pressing mechanisms 4 in sequence. Each set of hot pressing mechanisms 4 adjusts the pressing height and temperature according to the instructions of the main controller 5 to achieve segmented hot pressing. The continuously moving particleboard blank is compressed and its thickness is changed, ultimately obtaining particleboard of the desired thickness. The fine adjustment of the height adjustment device 9 ensures the uniformity and accuracy of each segment of pressing. The auxiliary heating plate 17 provides supplementary heating from below, making the board heated more evenly.

[0027] This invention significantly improves the quality and production efficiency of particleboard through multi-stage pressurization and temperature control, while reducing energy consumption, and has broad application prospects.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
