Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a device for softening and preserving wood for pencils. Background Technology

[0002] A pencil is a writing and drawing tool with a graphite or clay mixture as the lead, encased in a wooden, paper, or plastic barrel. Its core functions include writing, sketching, and marking. The hardness of the lead is adjusted by the ratio of graphite to clay. Wood softening treatment primarily involves heating in a steam oven and using chemical agents to alter the fiber structure, reducing the modulus of elasticity and increasing plastic deformation capacity. This process makes the wood easier to cut, grooving, and shaping, while ensuring it regains its rigidity and maintains its shape stability after drying. In pencil production, softened wood is easier to process into thin sheets to encase the lead and prevent cracking. Furthermore, after shaping, the expansion coefficient of the softened wood tends to match that of the graphite lead, preventing the lead from falling off due to temperature and humidity changes.

[0003] Traditional methods for softening pencil wood involve steam softening, natural drying, and soaking for preservation, which suffer from low efficiency and uneven penetration of preservatives. Therefore, it is particularly important to improve existing pencil wood softening and preservation treatment devices and design a new type of device to address these technical shortcomings and enhance the overall practicality of the device.

At the same time, it allows the wood to absorb the preservative evenly and quickly, improving the quality of wood preservation and enhancing the overall practicality of the wood softening and preservative treatment device, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wood softening and preservative treatment device for pencils includes a main body. One end of the main body has a treatment chamber.

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

[0021] Example:

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] A wood softening and preservative treatment device for pencils includes a main body 1. A treatment chamber 101 is located at one end of the main body 1. Multiple sets of equally spaced rotating rods 105 are rotatably connected inside the treatment chamber 101. A steam chamber 2 is located inside the main body 1 at the bottom of the treatment chamber 101. A water inlet 201 and a liquid inlet 202 are located on both sides of the steam chamber 2. A rotating shaft 204 is rotatably connected inside the steam chamber 2. A stirring rod 205 is fixedly connected to the outside of the rotating shaft 204 inside the steam chamber 2. A motor 203 is fixedly connected inside the main body 1 at the bottom of the treatment chamber 101. A motor 205 is located at the top of the steam chamber 2, near the stirring rod. A first jet pump 302 and a second jet pump 304 are fixedly connected to both sides of the processing chamber 101, respectively. A first air outlet 303 is provided at the bottom of the processing chamber 101, near the end of the first jet pump 302, and a second air outlet 306 is provided at the top of the processing chamber 101, away from the end of the first air outlet 303. The air outlet end of the second jet pump 304 is fixedly connected to the second air outlet 306 through a pipe 305. The drive end of the motor 203 is fixedly connected to the rotating shaft 204, and the air outlet end of the first jet pump 302 is fixedly connected to the first air outlet 303. The first air outlet 303 and the second air outlet 306 are designed diagonally. A heating device 3 is fixedly connected inside the main body 1 and at the bottom of the steam chamber 2. Multiple sets of equally spaced heating rods 301 are fixedly connected to the bottom of the steam chamber 2 and on both sides of the stirring rod 205. When the pencil wood softening and preservative treatment device is put into use, the wood is placed on the rotating rod 105 and pushed into the treatment chamber 101. The power is turned on, water enters the steam chamber 2 from the water inlet tank 201, and wood softener enters the steam chamber 2 from the liquid inlet tank 202 in an appropriate proportion. The drive end of the motor 203 rotates, thereby driving the rotating shaft 204 to rotate, which in turn drives the stirring rod 205 to rotate, thus mixing the water and wood softener. The heating device 3 boils the mixture of water and wood softener by heating the heating rod 301. The steam from the mixture is drawn away by the drive ends of the first jet pump 302 and the second jet pump 304. The first jet pump 302 sends the steam into the first vent 303 and then sprays it onto the bottom of the wood. The second jet pump 304 sends the steam into the pipe 305 and then sprays it onto the top of the wood from the second vent 306. Since the first vent 303 and the second vent 306 are diagonally designed, the steam circulates around the wood inside the treatment chamber 101, so that the wood and steam come into full and uniform contact, improving the quality and efficiency of softening.

[0024] Furthermore, a temperature and humidity sensor 4 is fixedly connected inside the processing chamber 101 and above the rotating rod 105. A second microwave generator 402 is fixedly connected inside the processing chamber 101 and above the temperature and humidity sensor 4. A first microwave generator 401 is fixedly connected inside the processing chamber 101 and below the rotating rod 105. The first microwave generator 401 and the second microwave generator 402 are diagonally designed. When the pencil wood softening and anti-corrosion treatment device is put into use, the power is turned on, and the temperature and humidity sensor 4 senses the temperature inside the processing chamber 101. Temperature and humidity control are crucial. When the wood is softened by steam, the first microwave generator 401 and the second microwave generator 402 emit microwaves to expand the wood fibers, increasing their contact efficiency with steam and further improving the quality and efficiency of softening. After softening is complete, the first microwave generator 401 and the second microwave generator 402 emit microwaves to accelerate the drying speed of the wood. When the wood is treated with preservatives, the first microwave generator 401 and the second microwave generator 402 emit microwaves to expand the wood fibers, increasing the efficiency of the wood in absorbing preservatives and improving work efficiency and quality.

[0025] The processing chamber 101 contains a first atomizing nozzle 501 fixedly connected inside and between the first microwave generator 401 and the first air outlet 303. A second atomizing nozzle 502 is fixedly connected inside the processing chamber 101 between the second microwave generator 402 and the second air outlet 306. A sliding groove 102 is provided inside the processing chamber 101. Liquid inlet pipes 5 are fixedly connected to the sides of both the first and second atomizing nozzles 501 and 502 away from the sliding groove 102. An insulation board 6 is provided inside the main body 1 and outside the processing chamber 101. When the pencil is softened with wood... When the anti-corrosion treatment device is put into use, the power is turned on. After the wood is softened and dried, the preservative liquid enters the first atomizing nozzle 501 and the second atomizing nozzle 502 from the inlet pipe 5. The first atomizing nozzle 501 and the second atomizing nozzle 502 atomize the preservative liquid and spray it onto the bottom and top of the wood respectively, which facilitates uniform absorption. The first microwave generator 401 and the second microwave generator 402 emit microwaves to expand the wood fibers, which improves the efficiency of wood absorption of preservative. This allows the wood to absorb the preservative evenly and quickly, thus improving the quality of wood preservation. The insulation board 6 reduces heat loss and saves energy.

[0026] Secondly, a lifting door 103 is slidably connected inside the slide 102, and an electric lifting rod 104 is fixedly connected inside the main body 1 and at the bottom of the lifting door 103. The drive end of the electric lifting rod 104 is fixedly connected to the lifting door 103. The slide 102 and the lifting door 103 are designed to be compatible. When the pencil wood softening and anti-corrosion treatment device is put into use, the power is turned on, the drive end of the electric lifting rod 104 rises, thereby driving the lifting door 103 to rise along the slide 102, thereby closing the main body 1. It can be opened and closed automatically, which is convenient to use and improves work efficiency. A pressure relief valve is provided on the top of the treatment chamber 101. When the air pressure inside the treatment chamber 101 is too high, it will automatically release air.

[0027] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0028] In this embodiment, the specific implementation scenario is as follows: In actual use, when the wood softening and preservative treatment device for pencils is put into use, the power is turned on, the drive end of the electric lifting rod 104 descends, thereby driving the lifting door 103 to descend along the slide 102, thus opening the main body 1. The wood is placed on the rotating rod 105 and pushed into the interior of the treatment chamber 101. The power is turned on, water enters the steam chamber 2 from the water inlet tank 201, and wood softener enters the steam chamber 2 from the liquid inlet tank 202 in an appropriate proportion. The drive end of the electric lifting rod 104 rises, thereby driving the lifting door 103 to rise along the slide 102. This shuts off the main body 1. The drive end of the motor 203 rotates, causing the rotating shaft 204 to rotate, which in turn causes the stirring rod 205 to rotate, thus mixing the water and wood softener evenly. The heating device 3 boils the water and wood softener mixture by heating the heating rod 301. The steam from the mixture is drawn away by the drive ends of the first jet pump 302 and the second jet pump 304. The first jet pump 302 sends the steam into the first vent 303 and then sprays it onto the bottom of the wood. The second jet pump 304 sends the steam into the pipe 305 and then sprays it onto the top of the wood from the second vent 306. Because the first vent 306... The design of 303 and the second air outlet 306 is diagonal, allowing steam to circulate around the wood within the processing chamber 101, ensuring comprehensive and uniform contact between the wood and steam, thus improving the quality and efficiency of softening. The first microwave generator 401 and the second microwave generator 402 emit microwaves that expand the wood fibers, increasing their contact efficiency with steam and further enhancing the quality and efficiency of softening. The insulation board 6 reduces heat loss, saving energy. After softening is complete, the microwaves emitted by the first microwave generator 401 and the second microwave generator 402 accelerate the drying process of the wood. The preservative solution enters from the inlet pipe 5. The preservative solution enters the first atomizing nozzle 501 and the second atomizing nozzle 502. The first atomizing nozzle 501 and the second atomizing nozzle 502 atomize the preservative solution and spray it onto the bottom and top of the wood respectively, which facilitates uniform absorption. The first microwave generator 401 and the second microwave generator 402 emit microwaves to expand the wood fibers, which improves the efficiency of wood absorption of preservative. This allows the wood to absorb the preservative evenly and quickly, thus improving the quality of wood preservation. Compared with existing wood softening and preservative treatment devices for pencils, this utility model improves the overall practicality of wood softening and preservative treatment devices for pencils through its design.
