Description

Technical Field

[0001] This utility model relates to the field of multi-layer board processing technology, specifically a drying device for multi-layer board processing. Background Technology

[0002] Multi-layer board is a sheet material made of three or more layers of wood, either rotary-cut into veneers or sliced ​​from timber, and then glued together with adhesives. It typically uses an odd number of veneer layers, with the grain direction of adjacent layers perpendicular to each other. Multi-layer board, also called plywood, is a commonly used material in furniture making. Typically, the top and inner veneers of multi-layer board are symmetrically arranged on both sides of the core layer. Common types include three-ply and five-ply. Plywood improves wood utilization and is a major way to save wood. During processing, the interior of the multi-layer board needs to be dried to prevent moisture from remaining inside the board. The processing of multi-layer boards can lead to cracking, affecting the overall efficiency and aesthetics of the board processing. For example, a wood drying device for multi-layer board processing, application number CN214250396U, includes an outer cover, a spacer fixedly connected inside the outer cover, a slot inside the spacer, a heating plate fixedly connected inside the slot, a support rod fixedly connected inside the heating plate, a sliding groove inside the spacer, a first slider slidably connected inside the sliding groove, and a support plate fixedly connected to one end of the first slider. However, the above-mentioned common types of drying devices for multi-layer board processing still have the following shortcomings in practical applications:

[0003] The layers of plywood are glued together, and the glue produces a large amount of harmful gases during the drying process. These harmful gases can harm the health of workers during long-term work. At the same time, the existing drying method involves placing a large number of boards in a drying chamber. Due to the large number of boards piled up, the boards in the middle cannot be dried properly during the drying process, so a secondary drying is required, which reduces work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a drying device for processing multi-layer boards, in order to solve the problems mentioned in the background art, where there is glue between the layers of multi-layer boards, and the glue generates a large amount of harmful gases during the drying process. These harmful gases can harm the health of workers during long-term work. At the same time, the existing drying method involves placing a large number of boards in the drying chamber, resulting in a large number of boards piling up. During the drying process, the boards cannot be dried completely because of the piling up, so a secondary drying is required, which reduces the work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for processing multi-layer boards, comprising a drying chamber, a cabinet door hinged to one side of the drying chamber, a blower heater fixedly installed on one side of the top of the drying chamber, an exhaust structure fixedly installed on the other side of the drying chamber, a board placement cart placed inside the drying chamber, and a first guide pipe fixedly connected to one side of the blower heater. ， The bottom of the first guide tube is fixedly connected to a flow guiding mechanism for diverting hot airflow.

[0006] Preferably, the flow guiding mechanism includes a second guide tube, and a plurality of first diversion tubes are fixedly connected to the outer side of the second guide tube. One end of each of the plurality of first diversion tubes is fixedly connected to a second diversion tube, and one end of the second diversion tube is provided with an air outlet to facilitate the gas in the blower heater to enter the interior of the drying oven.

[0007] Preferably, the exhaust structure includes an exhaust port, an exhaust fan is provided at the bottom of the exhaust port, a filter screen is snapped into the inner cavity of the exhaust port, and an exhaust thread is provided on the outer ring of the exhaust port. An external exhaust pipe is connected through the exhaust thread on the outer ring of the exhaust port, and harmful gases are filtered through the filter screen.

[0008] Preferably, the board placement cart includes a base, four casters are fixedly installed on the bottom of the base, a handle is fixedly installed on one side of the base, and support rods are snapped into the four corners of the top of the base. The boards are placed on the board placement box and pushed into the drying box by the handle and the casters.

[0009] Preferably, the bottom of the four support rods is fixedly installed with a plug rod, the top of the support rod is provided with a plug hole, the inner cavity of the support rod is provided with a fixing hole, and a pin is snapped into the fixing hole. The support rods on both sides of the plate placement cart are fixedly connected with a fixing rod. The height of the plate placement cart can be increased by the plug rod and the plug hole.

[0010] Preferably, a snap-fit ​​groove is provided on one side of the fixing rod, and a placement rod is snap-fitted between the two fixing rods. The placement rod can be fixed through the snap-fit ​​groove, and then the board to be dried can be placed on the placement rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: hot air can be transferred into the drying chamber through the guide pipe and the diversion pipe; water vapor and harmful gases generated during the drying process can be discharged from the drying chamber through the exhaust port, which can effectively reduce the harm caused by harmful gases to the workers. At the same time, it can prevent water vapor from condensing into water droplets and dripping onto the dried board. The assembly of the plug rod and plug hole on the support rod can effectively prevent the board from piling up, which can effectively improve the drying efficiency. The fixing rods on both sides can effectively prevent the board from tipping over and falling. Attached Figure Description
