Abstract
Description
Technical Field
[0001] This utility model relates to the field of particleboard processing technology, and in particular to a fine processing equipment for particleboard production. Background Technology
[0002] Particleboard (also known as chipboard or wood chipboard) is a board made by pressing wood shavings, adhesives, and other additives under high temperature and pressure. As the raw material for particleboard, the particle size and purity of the wood shavings have a direct impact on the quality of the particleboard during the production process.
[0003] CN220836135U discloses a wood shaving sorting machine, relating to the field of wood shaving sorting technology. In the process of wood shaving sorting, coarse sorting often leads to disordered particle size and poor quality of the separated wood shavings. The wood shaving sorting machine includes a main body, a pretreatment box, a feeding port, an outlet for excessively heavy debris, a base, a first sorting hood, a second sorting hood, support feet, a dispersing component, a sorting component, a primary collection component, and a secondary collection component. This wood shaving sorting machine, by setting a dispersing component, facilitates the initial dispersing of clumps of wood shavings. It also uses a sorting component to swirl the falling wood shavings inside the main body, allowing for the stratification of wood shavings of different weights. Simultaneously, the primary and secondary collection components enable multi-stage independent collection of the sorted wood shavings, thus achieving a multi-stage sorting effect.
[0004] Although the device uses airflow to sieve wood shavings, shavings that are not completely broken up will be discharged directly because the airflow cannot carry them. Smaller shavings may be carried into the wrong collection box due to larger shavings being wrapped up, resulting in ineffective sorting and fine sieving of the wood shavings. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a device for refining particleboard chips in the production of homogeneous particleboard.
[0006] This utility model is achieved using the following technical solution: a particleboard refining equipment for homogeneous particleboard production, comprising a removal cylinder, a base frame fixedly connected to the surface of the removal cylinder, a feed channel fixedly connected to the top of the removal cylinder, a removal mechanism provided inside the removal cylinder, an impurity outlet fixedly connected to the bottom of the removal cylinder, a conveying pipe fixedly connected to the right end of the removal cylinder, a buffer plate fixedly connected to the right end of the conveying pipe, and a sorting mechanism provided at the right end of the conveying pipe;
[0007] The impurity removal mechanism includes a first motor, a dispersing shaft fixedly connected to the output end of the first motor, a dispersing rod fixedly connected to the surface of the dispersing shaft, a blowing pipe fixedly connected to the surface of the impurity removal cylinder, a blower fixedly connected to the end of the blowing pipe away from the impurity removal cylinder, and a filter plate fixedly connected to the inner wall of the impurity removal cylinder.
[0008] As a further improvement to the above solution, a support is provided on the surface of the feeding channel, the top of the support is fixedly connected to the bottom of the first motor, the surface of the dispersing shaft is rotatably connected to the inner wall of the feeding channel, and the bottom of the blower is fixedly connected to the top of the base frame.
[0009] As a further improvement to the above scheme, the number of dispersing rods is set to several, which are evenly arranged on the surface of the dispersing shaft.
[0010] The above technical solution uses a dispersing rod that is evenly distributed on the surface of the dispersing shaft to rotate under the drive of the first motor, which breaks up the input wood shavings, removes the impurities entangled inside the wood shavings, and ensures the purity of the wood shavings after screening.
[0011] As a further improvement to the above scheme, the direction of the blowing pipe is set obliquely upward with reference to the surface of the impurity removal cylinder.
[0012] Through the above technical solution, the airflow blown by the blower spirals and rises inside the impurity removal cylinder through the inclined blowing pipe, blowing the broken wood shavings toward the conveying pipe. Impurities that cannot be blown away are filtered through the filter plate and discharged from the impurity outlet. At the same time, the filter plate isolates the wood shavings inside the impurity removal cylinder and continues to blow them apart to remove impurities, ensuring the purity of the wood shavings. Meanwhile, the buffer plate blocks and slows down the wood shavings blown into the conveying pipe by the airflow, preventing the wood shavings driven by the high-speed airflow from flying directly out of the device.
[0013] As a further improvement to the above solution, the sorting mechanism includes a sorting box, a rolling shaft rotatably connected to the inner wall of the sorting box, a roller fixedly connected to the surface of the rolling shaft, a second motor fixedly connected to one end of the rolling shaft, a drum rotatably connected to the surface of the roller, screening holes opened on the surface of the drum, a connecting groove opened at the left end of the drum, a limit plate fixedly connected to the surface of the drum, a first discharge hopper fixedly connected to the right end of the sorting box, and a second discharge hopper fixedly connected to the rear end of the sorting box.
[0014] The above technical solution separates the wood shavings with smaller particle sizes into the internal cavity of the sorting box through the screening holes set on the surface of the drum, and discharges them from the second discharge hopper. The wood shavings with larger particle sizes are intercepted inside the drum and discharged from the first discharge hopper, thus separating wood shavings of different particle sizes and ensuring that the density and texture of the subsequent particleboard are uniform.
[0015] As a further improvement to the above solution, the inner wall of the connecting groove is rotatably connected to the surface of the conveying pipe, and a bracket is provided on the surface of the sorting box, with the top of the bracket fixedly connected to the bottom of the second motor.
[0016] As a further improvement to the above solution, there are two of each of the rolling shaft and the limiting plate, and the number of rollers is provided with a cleaning mechanism. The surface of the limiting plate is slidably connected to the surface of the sorting box.
[0017] The above technical solution uses a second motor to drive the rolling shaft to rotate, causing the rollers to rotate on the four roller surfaces due to friction. At the same time, the limiting plates at both ends hold the top of the sorting box to prevent the rollers from deviating from their position and ensure the stability of the device.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] This invention features a purification mechanism. Specifically, a dispersing rod, evenly distributed on the surface of a dispersing shaft, rotates under the drive of a first motor to break up the input wood shavings, allowing impurities entangled inside the shavings to be removed, ensuring the purity of the shavings after screening. An airflow blown by a blower spirals upwards inside the purification cylinder through a tilted blowing pipe, blowing the broken shavings toward the conveying pipe. Impurities that cannot be blown away are filtered through a filter plate and discharged from the impurity outlet. At the same time, the filter plate isolates the shavings inside the purification cylinder, continuing to disperse and remove impurities, ensuring the purity of the shavings.
[0020] This invention employs a sorting mechanism. Specifically, a second motor drives a rolling shaft to rotate, causing the rollers to rotate on four roller surfaces due to friction. Simultaneously, limit plates at both ends secure the top of the sorting box, preventing the rollers from deviating from their position and ensuring the stability of the device. Smaller wood shavings are sieved through screening holes on the roller surface into the internal cavity of the sorting box and discharged from the second discharge hopper. Larger wood shavings are intercepted inside the roller and discharged from the first discharge hopper, thus separating wood shavings of different sizes and ensuring that the subsequent particleboard has a uniform density and texture.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0029] Example:
[0030] Please combine Figure 1-5 This embodiment provides a particleboard refining equipment for homogeneous particleboard production, comprising a removal cylinder 1, a base frame 2 fixedly connected to the surface of the removal cylinder 1, a feeding channel 3 fixedly connected to the top of the removal cylinder 1, a removal mechanism 4 provided inside the removal cylinder 1, an impurity outlet 5 fixedly connected to the bottom of the removal cylinder 1, a conveying pipe 6 fixedly connected to the right end of the removal cylinder 1, and a buffer plate 7 fixedly connected to the right end of the conveying pipe 6. The buffer plate 7 blocks and slows down the particleboard blown into the conveying pipe 6 by the airflow, preventing the particleboard driven by the high-speed airflow from flying directly out of the device. A sorting mechanism 8 is provided at the right end of the conveying pipe 6.
[0031] The impurity removal mechanism 4 includes a first motor 401, a dispersing shaft 402 fixedly connected to the output end of the first motor 401, a dispersing rod 403 fixedly connected to the surface of the dispersing shaft 402, a blowing pipe 404 fixedly connected to the surface of the impurity removal cylinder 1, a blower 405 fixedly connected to the end of the blowing pipe 404 away from the impurity removal cylinder 1, and a filter plate 406 fixedly connected to the inner wall of the impurity removal cylinder 1.
[0032] A support is provided on the surface of the feed channel 3. The top of the support is fixedly connected to the bottom of the first motor 401. The surface of the dispersing shaft 402 is rotatably connected to the inner wall of the feed channel 3. The bottom of the blower 405 is fixedly connected to the top of the base frame 2.
[0033] Several dispersing rods 403 are evenly arranged on the surface of the dispersing shaft 402. The dispersing rods 403, which are evenly distributed on the surface of the dispersing shaft 402, rotate under the drive of the first motor 401, breaking up the input wood shavings and removing the impurities entangled inside the wood shavings, thus ensuring the purity of the wood shavings after screening.
[0034] The direction of the blowing pipe 404 is set to be obliquely upward with the surface of the impurity removal cylinder 1 as the reference. The airflow blown by the blower 405 spirals and rises inside the impurity removal cylinder 1 through the blowing pipe 404 installed at an inclined angle, blowing the broken wood shavings toward the conveying pipe 6. Impurities that cannot be blown away are filtered through the filter plate 406 and discharged from the impurity outlet 5. At the same time, the filter plate 406 isolates the wood shavings inside the impurity removal cylinder 1 and continues to blow away impurities to ensure the purity of the wood shavings.
[0035] The sorting mechanism 8 includes a sorting box 801. A rolling shaft 802 is rotatably connected to the inner wall of the sorting box 801. A roller 803 is fixedly connected to the surface of the rolling shaft 802. A second motor 804 is fixedly connected to one end of the rolling shaft 802. A drum 805 is rotatably connected to the surface of the roller 803. A screening hole 806 is opened on the surface of the drum 805. A connecting groove 807 is opened at the left end of the drum 805. A limit plate 808 is fixedly connected to the surface of the drum 805. A first discharge hopper 809 is fixedly connected to the right end of the sorting box 801. A second discharge hopper 810 is fixedly connected to the rear end of the sorting box 801. The shavings with smaller particle size are screened into the internal cavity of the sorting box 801 through the screening hole 806 on the surface of the drum 805 and discharged from the second discharge hopper 810. The shavings with larger particle size are intercepted inside the drum 805 and discharged from the first discharge hopper 809. This separates shavings of different particle sizes to ensure that the density and texture of the subsequent particleboard are uniform.
[0036] The inner wall of the connecting groove 807 is rotatably connected to the surface of the conveying pipe 6, and a bracket is provided on the surface of the sorting box 801. The top of the bracket is fixedly connected to the bottom of the second motor 804.
[0037] There are two rolling shafts 802 and two limiting plates 808. There are four impurity removal mechanisms for the rollers 803. The surface of the limiting plate 808 is slidably connected to the surface of the sorting box 801. The second motor 804 drives the rolling shaft 802 to rotate, so that the surface of the rollers 803 drives the drum 805 to rotate on the surface of the four rollers 803 by friction. At the same time, the limiting plates 808 at both ends lock the top of the sorting box 801 to prevent the drum 805 from deviating from its position and ensure the stability of the device.
[0038] The implementation principle of the particleboard refining equipment for homogeneous particleboard production in this application embodiment is as follows: When using the device, particleboard is poured in from the top of the feed channel 3. The first motor 401 is started to drive the dispersing shaft 402 and the dispersing rod 403 to rotate. The dispersing rod 403, which is evenly distributed on the surface of the dispersing shaft 402, rotates under the drive of the first motor 401, breaking up the input particleboard and removing impurities entangled inside the particleboard, ensuring the purity of the particleboard after screening. It also breaks up clumps of particleboard, removing internal impurities such as stones and bark, and then feeds the particleboard into the feed channel. Inside the impurity removal cylinder 1, the blower 405 blows airflow through the blowing pipe 404 to disperse the wood shavings. Impurities pass through the holes in the filter plate 406 and are discharged from the device through the impurity outlet 5. The airflow blown by the blower 405 spirals and rises inside the impurity removal cylinder 1 through the inclined blowing pipe 404, blowing the dispersed wood shavings toward the conveying pipe 6. Impurities that cannot be blown away are filtered by the filter plate 406 and discharged from the impurity outlet 5. At the same time, the filter plate 406 isolates the wood shavings inside the impurity removal cylinder 1, continuing to disperse and remove impurities, ensuring that the wood shavings are properly dispersed. The purity of the shavings is ensured. The shavings, sent to the conveyor pipe 6 by the airflow, are intercepted by the buffer plate 7 and then drawn into the drum 805. The buffer plate 7 slows down the shavings blown into the conveyor pipe 6 by the airflow, preventing the high-speed airflow from pushing the shavings directly out of the device. Driven by the second motor 804, the roller 803 drives the drum 805 to rotate. Under the limiting protection of the limiting plate 808, the drum 805 sieves shavings of different particle sizes. The second motor 804 drives the rolling shaft 802 to rotate, causing the surface of the roller 803 to drive the drum 805 through friction. The four rollers 803 rotate, while the limiting plates 808 at both ends lock the top of the sorting box 801 to prevent the roller 805 from deviating from its position and ensure the stability of the device. At the same time, the shavings with smaller particle size are screened into the cavity inside the sorting box 801 through the screening holes 806 set on the surface of the roller 805, while the shavings with larger particle size are intercepted inside the roller 805. The shavings of different particle sizes are separated to ensure that the density and texture of the subsequent particleboard are uniform. After the sorting is completed, the shavings of different particle sizes are taken out from the first discharge hopper 809 and the second discharge hopper 810 respectively.
[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
