Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a microwave heating device for particleboard production. Background Technology

[0002] Particleboard is a type of engineered wood product made from wood or other wood fibers through a process of shaving preparation, drying and sorting, application of urea-formaldehyde resin or other suitable adhesives, laying, pre-pressing, and hot-pressing. Currently, most existing particleboard hot-pressing devices use hot presses, which require a heating process, thus lengthening the overall production time and affecting production efficiency.

[0003] In the prior art, such as the microwave equipment for preheating particleboard disclosed in Chinese Publication No. CN213766301U, there is a conveyor belt mounted on a support for transporting particleboard and a microwave heating furnace located above the conveyor belt. The microwave heating furnace is composed of several microwave heating boxes connected in sequence and accessible to the conveyor belt. Each microwave heating box includes an inner heating box plate, a heating cavity enclosed by the heating box plate, and an outer shell to prevent microwave leakage. The lower part of the microwave heating box has an opening for the particleboard to pass through. Several sets of microwave generators are installed on the heating box plate above the heating cavity. A microwave power supply frame, a control console, and an electrical control cabinet are located on one side of the microwave heating furnace. The microwave power supply frame is equipped with a microwave power supply, and the control console has an operation panel. This equipment can microwave heat the pre-pressed particleboard before it enters the hot press, increasing the core layer temperature of the board, thereby reducing the heating time, improving production efficiency, and saving energy.

[0004] The above-mentioned technology has achieved the effect of allowing multiple people to use it simultaneously, but there are still some shortcomings, specifically: Traditional particleboard microwave heating equipment generally suffers from insufficient structural rigidity. The single-point support structure is prone to displacement deviation due to equipment vibration, affecting the accuracy of board transmission. Furthermore, the lack of a pressure roller structure makes it easy for material to shift during discharge. Moreover, when dealing with boards of different thicknesses, pressure adjustment relies on manual adjustment, lacking an elastic compensation mechanism and resulting in long downtime for adjustment.

It adopts a symmetrically distributed support column and reinforcing rod to form a stable frame, and works with a motor-driven double-end rotating roller and a synchronously running conveyor belt to ensure smooth material conveying and balanced force. The pressure block system with sliding block and spring linkage can automatically adjust the pressure according to the thickness of the board. With the help of the lever-type quick disassembly and assembly structure, the equipment debugging and maintenance time is greatly shortened, and the whole system realizes efficient and stable continuous production, thereby solving the problems mentioned in the background technology.

The modular design of the fixing ring and protective rod facilitates quick disassembly and maintenance, reducing equipment downtime caused by dust accumulation or wear, and improving the overall safety and reliability of the production process.

The cover 11 is connected by a limiting... The slot 12 is slidably connected to the fixed plate 8. The right side of the cover 11 has a feed inlet 14, and the left side of the cover 11 has a discharge outlet 15.

[0020] In this embodiment, the integrated support structure 1 and modular functional components are designed in a coordinated manner to significantly improve the equipment's operational efficiency and processing quality.

[0021] Example 2: Figure 1 , Figure 3 , Figure 4 As shown, a heat-conducting plate 33 is fixedly installed on the surface of the cover 11, and a heat sink 34 is provided on the surface of the heat-conducting plate 33. A fixing rod 35 is fixedly installed on the surface of the fixing plate 8, and a fixing ring 36 is fixedly installed on the surface of the fixing rod 35. A protective rod 37 is provided inside the fixing ring 36. The heat-conducting plate 33 is symmetrically distributed at the front and rear ends of the cover 11, the heat sink 34 is evenly distributed on the surface of the heat-conducting plate 33, the fixing rod 35 is evenly distributed at the four corners of the surface of the heat-conducting plate 33, and the protective rod 37 is evenly distributed inside the fixing ring 36.

[0022] In this embodiment, the thermal management efficiency and operational stability of the microwave heating equipment are enhanced. By adding a heat-conducting plate 33 and a heat sink 34 combination to the surface of the cover 11, an efficient heat conduction path is formed, which not only accelerates the transfer of heat to the board but also timely removes excess heat, effectively avoiding material deterioration caused by local overheating. The three-level linkage mechanism of fixing rod 35-fixing ring 36-protective rod 37 integrated in the fixing plate 8 not only improves the connection rigidity between the components but also forms a physical barrier for key parts through the protective rod 37, reducing the risk of failure caused by vibration or accidental contact during production. This makes the heat distribution more uniform and the equipment operation more stable, while also taking into account operational safety. Compared with the traditional structure, this significantly improves the particleboard processing quality and the service life of the equipment.

[0023] The working principle of this embodiment is as follows: First, place the bracket 1 in the desired position, ensuring the support column 2 and reinforcing rod 3 firmly support the bracket 1. Then, start the motor 4, causing the rotating roller 5 to drive the conveyor belt 6 to rotate in the middle of the bracket 1. Next, place the sheet material at the top of the conveyor belt 6, and transportation can begin. The sheet material enters the interior of the cover 11 through the feed inlet 14 and moves through the bottom end of the heating roller 10. The heating roller 10 rotates in the middle of the fixed plate 8 via the rotating rod 9 to heat the sheet material. The heating plate 13 inside the cover 11 can also heat the sheet material. After heating, the cover 11 can be moved out through the discharge port 15. During the movement, it moves along the bottom of the pressure roller 23. The pressure roller 23 rotates in the middle of the sliding block 20 via the rotating rod 22. When facing plates of different thicknesses, the spring force of the spring 24 allows the sliding block 20 to slide inside the support plate 16 through the sliding groove 17. The guide block 21 slides inside the support plate 16 through the guide groove 18 to accommodate plates of different thicknesses. During use, the heat-conducting plate 33 can conduct excess heat from inside the cover 11 and dissipate it through the heat sink 34. During the process, the protective rod 37, which is fixed to the surface of the cover 11 by the fixing rod 35 and the fixing ring 36, can protect the heat-conducting plate 33 and the heat sink 34 from damage caused by bumps. When the pressure roller 23 needs to be replaced after a long period of use, first pinch the locking block 31 and pull it upward, so that the locking block 31 slides upward inside the locking rod 28 through the mounting groove 32 and the fixing groove 30. When the locking block 31 has completely slid out of the inside of the locking rod 28, then pinch the stop block 29 and pull it outward, so that the locking rod 28 slides inside the pressure block 25 through the locking groove B27 and inside the support plate 16 through the locking groove A19. Slide the lever 28 until it is completely slid out of the support plate 16 and the pressure block 25 through the slots A19 and B27. Then, pinch the pressure block 25 and pull it upwards, so that the pressure block 25 drives the side block 26 to slide out of the support plate 16 through the sliding groove 17 and the guide groove 18. At this time, the sliding block 20 and the guide block 21 can be removed from the support plate 16 for replacement. When it is necessary to maintain the heating plate 13 and the heating roller 10, pinch the cover 11 and pull it upwards, so that the cover 11 slides upwards on the surface of the fixing plate 8 through the limiting groove 12. After the cover 11 is removed from the top of the side platform 7, maintenance can be performed.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
