Description

Technical Field

[0001] This utility model relates to the technical field of balsa wood drying equipment, and in particular to a drying device for controlling the moisture content of balsa wood. Background Technology

[0002] Balsa wood is the world's lowest density commercial timber and also the lightest wood. This tree is evergreen and has a tall trunk. Its leaves resemble those of a sycamore tree, its five yellowish-white petals resemble those of a hibiscus flower, and its fruit splits open like cotton. During the production and processing of balsa wood, drying equipment is used to dry the internal moisture of the wood and control its moisture content to meet the needs of different applications.

[0003] An existing quick-drying device for balsa wood plywood (publication number: CN218973046U) has at least the following drawbacks: the device uses a drying room to dry the balsa wood, but drying cannot be carried out during the loading and unloading of the balsa wood, making the drying process unsustainable. In the prior art, there is a microwave dryer equipped with a conveyor belt, which can achieve continuous and efficient drying of balsa wood and has high precision in controlling the moisture content. However, when loading the balsa wood, manual handling is required to place the balsa wood pieces one by one on the conveyor belt for feeding. Balsa wood with high moisture content is heavy and bulky, making manual handling laborious and affecting the drying efficiency of the balsa wood. Therefore, this utility model is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying device for controlling the moisture content of balsa wood.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drying device for controlling the moisture content of balsa wood includes a microwave dryer. A feeding assembly is provided on the front side of the microwave dryer. The feeding assembly includes a feeding rack fixed on the front side of the microwave dryer. A lifting plate is slidably arranged inside the feeding rack. Connecting plates are fixed inside the feeding rack near both the front and rear sides. A cross drive frame is rotatably connected inside the feeding rack near the rear side. A drive screw is rotatably connected inside the cross drive frame. A push plate is threadedly connected to the outer wall of the drive screw. A support roller is rotatably connected inside the rear side of the feeding rack. The support roller is parallel to the conveyor belt of the microwave dryer.

[0007] As a further embodiment of this utility model, hydraulic rods are fixed on both the left and right sides of the outer wall of the feeding rack. A drive plate is fixed to one end of the extension rod of the hydraulic rod. The bottom end of the drive plate is fixed to the top surface of the lifting plate. A first motor is fixed to one side of the feeding rack. The output shaft of the first motor is fixed to one side of the cross drive frame. A second motor is fixed to the front side of the cross drive frame. The output shaft of the second motor is fixed to the front end of the drive screw.

[0008] As a further embodiment of this utility model, the top surface of the lifting plate is provided with sliding grooves near the left and right sides, and a positioning plate is slidably arranged inside the sliding groove. An adjusting screw is threadedly connected to one side of the driving plate, and the adjusting screw is rotatably connected to one side of the positioning plate.

[0009] As a further embodiment of this utility model, two first limiting rods are fixed on one side of the positioning plate, the first limiting rods are slidably disposed with one side of the drive plate, two second limiting rods are fixed inside the sliding groove, and the positioning plate is slidably disposed with the outer wall of the second limiting rods.

[0010] As a further embodiment of this utility model, the front bottom end of the cross drive frame abuts against the front side of the corresponding connecting plate, and a positioning rod is fixed on the top surface of the cross drive frame.

[0011] As a further embodiment of this utility model, the top surface of the lifting plate is provided with two fork grooves.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting up a feeding rack and installing a rotatable cross drive frame above it to avoid forklifts and transport balsa wood into the feeding rack, the top layer of balsa wood is then lifted sequentially by a drive lifting plate to the same height as the microwave dryer conveyor belt. Subsequently, a drive push plate pushes the balsa wood into the microwave dryer conveyor belt, achieving automated and continuous feeding of balsa wood. This effectively increases the feeding efficiency of balsa wood and the drying and moisture control efficiency of balsa wood. Attached Figure Description

[0022] like Figures 1-4 As shown, a drying device for controlling the moisture content of balsa wood includes a microwave dryer 1. A feeding assembly is provided on the front side of the microwave dryer 1. The feeding assembly includes a feeding rack 2 fixed on the front side of the microwave dryer 1. A lifting plate 201 is slidably arranged inside the feeding rack 2. Connecting plates 202 are fixed inside the feeding rack 2 near both the front and rear sides. A cross drive frame 203 is rotatably connected inside the feeding rack 2 near the rear side. A drive screw 204 is rotatably connected inside the cross drive frame 203. A push plate 205 is threadedly connected to the outer wall of the drive screw 204. A support roller 206 is rotatably connected inside the rear side of the feeding rack 2. The support roller 206 is parallel to the conveyor belt of the microwave dryer 1.

[0023] like Figures 2-4As shown, in this embodiment, hydraulic rods are fixed to both the left and right sides of the outer wall of the loading rack 2. A drive plate 207 is fixed to one end of the hydraulic rod's telescopic rod. The bottom end of the drive plate 207 is fixed to the top surface of the lifting plate 201. A first motor is fixed to one side of the loading rack 2. The output shaft of the first motor is fixed to one side of the cross drive frame 203. A second motor is fixed to the front side of the cross drive frame 203. The output shaft of the second motor is fixed to the front end of the drive screw 204. By starting the first motor, the cross drive frame 203 is rotated, making it perpendicular to the top surface of the loading rack 2. At this time, a forklift is used to transport the stacked balsa wood to the top of the loading rack 2, place it inside the loading rack 2, and stack it on the lifting plate 201. The top surface is then driven, and the cross drive frame 203 is reset and its front bottom end abuts against the front side of the corresponding connecting plate 202. At this time, the hydraulic rod is activated to drive the drive plate 207 to rise, thereby moving the top layer of balsa wood to the same height as the support roller 206 and the microwave dryer 1. Then, the second motor is activated to drive the drive screw 204 to rotate, so that the push plate 205 slides towards the microwave dryer 1 and pushes the top layer of balsa wood along the top surface of the support roller 206 into the transmission belt of the microwave dryer 1. Then, the lifting plate 201 is driven to move the lower layer of balsa wood to the push plate 205 for continued feeding, realizing automated continuous feeding of balsa wood, effectively increasing the feeding efficiency of balsa wood and increasing the drying and moisture control efficiency of balsa wood.

[0024] like Figures 2-4 As shown in this embodiment, the top surface of the lifting plate 201 is provided with sliding grooves 3 near the left and right sides. A positioning plate 301 is slidably arranged inside the sliding groove 3. An adjusting screw 302 is threadedly connected to one side of the driving plate 207. The adjusting screw 302 is rotatably connected to one side of the positioning plate 301. By rotating the adjusting screw 302 according to the required width of the balsa wood to be dried, the two positioning plates 301 are driven to move closer to each other, so that the distance between the two positioning plates 301 is slightly larger than the width of the balsa wood, which plays a limiting role on the left and right sides of the balsa wood and prevents the balsa wood from tilting when the push plate 205 pushes the balsa wood.

[0025] like Figures 2-4 As shown, in this embodiment, two first limiting rods 4 are fixed on one side of the positioning plate 301. The first limiting rods 4 are slidably disposed with one side of the drive plate 207. Two second limiting rods 401 are fixed inside the sliding groove 3. The positioning plate 301 is slidably disposed with the outer wall of the second limiting rods 401. The first limiting rods 4 and the second limiting rods 401 can limit and support the movement of the positioning plate 301.

[0026] like Figures 2-4As shown, in this embodiment, the front bottom end of the cross drive frame 203 abuts against the front side of the corresponding connecting plate 202. A positioning rod 5 is fixed on the top surface of the cross drive frame 203. When the first motor is started, the cross drive frame 203 is rotated via the positioning rod 5, causing the positioning rod 5 to abut against the top surface of the loading rack 2, making the cross drive frame 203 perpendicular to the top surface of the loading rack 2, thereby achieving the positioning function of the cross drive frame 203.

[0027] like Figures 2-4 As shown in this embodiment, the top surface of the lifting plate 201 has two fork slots 6. By setting the fork slots 6, the fork of the forklift can exit through the fork slots 6 after the forklift puts the balsa wood into the loading rack 2.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, when it is necessary to control the moisture content of balsa wood during drying, the adjusting screw 302 is rotated according to the required width of the balsa wood to be dried, driving the two positioning plates 301 to move closer to each other, so that the distance between the two positioning plates 301 is slightly larger than the width of the balsa wood, thus limiting the left and right sides of the balsa wood. The first motor is started to drive the cross drive frame 203 to rotate, so that the positioning rod 5 abuts against the top surface of the loading rack 2, making the cross drive frame 203 perpendicular to the top surface of the loading rack 2. At this time, a forklift is used to transport the stacked balsa wood to the top of the loading rack 2, and place it inside the loading rack 2 and stack it on the top surface of the lifting plate 201. The frame can be withdrawn through the fork slot 6, and then the cross drive frame 203 is driven to reset and its front bottom end abuts against the front side of the corresponding connecting plate 202. At this time, the hydraulic rod is activated to drive the drive plate 207 to rise, thereby moving the uppermost balsa wood to the same height as the support roller 206 and the microwave dryer 1. Then, the second motor is activated to drive the drive screw 204 to rotate, so that the push plate 205 slides towards the microwave dryer 1 and pushes the uppermost balsa wood along the top surface of the support roller 206 into the transmission belt of the microwave dryer 1. Then, the lifting plate 201 is driven to move the lower balsa wood to the push plate 205 for continued feeding, realizing automated continuous feeding of balsa wood, effectively increasing the feeding efficiency of balsa wood and increasing the drying and moisture control efficiency of balsa wood.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
