Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood waste recycling technology, and in particular to a wood waste recycling device. Background Technology
[0002] Timber is a widely used material in the decoration and construction industry. Plywood or panels in wood panel processing are mostly made from logs. Wood product manufacturers generate a lot of wood waste and scraps in their daily production process. Manufacturers usually recycle these scraps for other uses.
[0003] A search revealed Chinese Patent Publication No. CN220373485U, which discloses a wood processing waste recycling device. The device includes a recycling box with four fixed casters at the bottom corners and support frames fixed on the front and rear sides of the top. This technical solution involves crushing and screening wood waste during use. However, it lacks a separation structure for ferromagnetic impurities (such as iron nails and steel sheets). Since wood processing waste often contains ferromagnetic metal impurities, if these impurities are not effectively removed, they can cause wear, jamming, or even damage to the equipment during subsequent recycling processes (such as pelleting), severely affecting recycling efficiency and equipment safety, and failing to meet usage requirements. Therefore, this paper proposes a wood waste recycling device to address the aforementioned problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a wood waste recycling device to solve the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A wood waste recycling device includes a processing box, a crushing box communicating with the top of the processing box, a guide hopper on the top of the crushing box, a magnetic conveying mechanism inside the processing box, a scraping component attached to the bottom of the magnetic conveying mechanism inside the processing box, a screening component located below the scraping component inside the processing box, and a crushing mechanism extending to the outside of the crushing box inside the crushing box.
[0007] The magnetic conveying mechanism includes two drive rollers that are rotatably mounted inside the processing box. A drive motor is fixedly mounted on the rear side of the processing box. The output shaft of the drive motor is fixedly connected to the drive rollers. A conveyor belt is driven between the outer sides of the two drive rollers. Several magnetic blocks that are evenly distributed are fixedly mounted on the outer side of the conveyor belt.
[0008] Preferably, the scraping assembly includes a support frame, which is fixedly installed inside the processing box and located below the conveyor belt. A support block located at the top of the support frame is fixedly installed inside the processing box. A scraper extending to its front side and abutting the bottom of the magnetic block is movably installed inside the support block. A collection box extending through to the rear side of the processing box is movably installed inside the support frame. A guide plate located on the right side of the support frame and below the conveyor belt is fixedly installed inside the processing box.
[0009] Preferably, the screening assembly includes a screen plate, which is installed inside the processing box and below the guide plate and the support frame. An inclined plate located at the bottom of the screen plate is fixedly installed inside the processing box. A vibration motor is fixedly installed at the bottom of the screen plate. The left and right sides of the processing box have discharge ports located above the screen plate and the inclined plate, respectively.
[0010] Preferably, the crushing mechanism includes two drive shafts rotatably mounted between the inner walls of the crushing chamber and extending to its outer side. A crushing roller located inside the crushing chamber is fixedly mounted on the outer side of the drive shaft. A control motor is fixedly mounted on the rear side of the crushing chamber, and the output shaft of the control motor is fixedly connected to the drive shaft on the left side. Several interleaved grinding teeth are fixedly mounted on the outer side of each of the two crushing rollers. A gearbox located outside the drive shaft is fixedly mounted on the front side of the crushing chamber.

[0013] Preferably, the guide plate, screen plate and inclined plate are all designed with an inclined structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This wood waste recycling device uses a magnetic conveyor mechanism with magnetic blocks on the conveyor belt to simultaneously transport the scrap and adsorb ferromagnetic impurities during transport, avoiding the need for additional power to drive separation in traditional magnetic separation equipment. The scraper of the scraping component is designed to fit snugly against the bottom of the magnetic block, which can efficiently clean impurities attached to the surface of the magnetic block, preventing the accumulation of impurities from reducing the magnetic separation efficiency. This ensures that ferromagnetic impurities (such as iron nails and steel sheets) are continuously and thoroughly separated from the scrap, preventing them from entering subsequent processing stages, damaging the equipment, or affecting product quality.
[0016] This wood waste recycling device enhances the crushing effect of wood waste through the staggered crushing teeth design of the crushing mechanism. The independent drive of the drive motor and the control motor ensures crushing efficiency. The inclined screen plate of the screening component is combined with the vibrating motor, which not only accelerates the classification and screening of the crushed material, but also guides coarse and fine particles to be discharged from different outlets through the inclined plate. This realizes the integrated continuous operation of "crushing-magnetic separation-screening", which effectively improves the practicality and reliability of the device. Attached Figure Description

[0027] Example
[0028] like Figures 1 to 5 As shown, this utility model provides a technical solution: a wood waste recycling device, including a processing box 1, which serves as the core load-bearing structure of the device. A box door 11 is movably installed on the front side of the processing box 1, and an observation window 12 is opened inside the box door 11 to observe the flow of the crushed material inside the processing box 1 in real time. A crushing box 2, which communicates with the inside of the processing box 1, is fixedly installed on the top of the processing box 1. The crushing box 2 has a dedicated cavity for crushing structure, and a guide hopper 3 is fixedly installed on the top of the crushing box 2 to prevent waste from scattering or accumulating at the feed inlet and to improve the feeding efficiency.
[0029] A magnetic conveying mechanism 4 is movably installed inside the processing box 1. The magnetic conveying mechanism 4 includes two drive rollers 41, which are rotatably installed inside the processing box 1. A drive motor 42 is fixedly installed on the rear side of the processing box 1. The output shaft of the drive motor 42 is fixedly connected to the drive rollers 41. A conveyor belt 43 is installed between the outer sides of the two drive rollers 41. Several magnetic blocks 44 are fixedly installed on the outer side of the conveyor belt 43 and are evenly distributed. The magnetic blocks 44 are used to adsorb ferromagnetic impurities, preventing them from entering the subsequent screening or processing stages and damaging the equipment. This wood waste recycling device, by setting the magnetic blocks 44 on the conveyor belt 43 in the magnetic conveying mechanism 4, simultaneously completes the transportation of broken materials and the adsorption of ferromagnetic impurities during the conveying process, avoiding the problem of traditional magnetic separation equipment requiring additional power to drive separation.
[0030] Inside the processing box 1, a scraping assembly 5 is fixedly installed and attached to the bottom of the magnetic conveying mechanism 4. The scraping assembly 5 includes a support frame 51, which is fixedly installed inside the processing box 1 and located below the conveyor belt 43. A support bracket 511, which is sleeved on the outside of the support frame 51, is fixedly installed on the rear side of the inner wall of the processing box 1. Inside the processing box 1, a support block 52 is fixedly installed at the top of the support frame 51. Inside the support block 52, a scraper 53 is movably installed, extending to its front side and attached to the bottom of the magnetic block 44. The support block 52 and the scraper 53 are connected by bolt threads, which facilitates the quick installation of the scraper 53. For disassembly and maintenance, a collection box 54 is movably installed inside the support frame 51, extending to the rear side of the processing box 1, to temporarily store the scraped ferromagnetic impurities for centralized cleaning and recycling. Inside the processing box 1, a guide plate 55 is fixedly installed on the right side of the support frame 51 and below the conveyor belt 43. Through the design of the scraper 53 of the scraping component 5 fitting against the bottom of the magnetic block 44, impurities attached to the surface of the magnetic block can be efficiently cleaned, preventing the accumulation of impurities from causing a decrease in magnetic separation efficiency. This ensures that ferromagnetic impurities (such as iron nails and steel sheets) are continuously and thoroughly separated from the scrap, preventing them from entering subsequent processing stages, damaging equipment, or affecting product quality.
[0031] The processing box 1 is equipped with a screening component 6 located below the scraping component 5. The screening component 6 includes a screen plate 61, which is installed inside the processing box 1 and below the guide plate 55 and the support frame 51. The processing box 1 is also equipped with an inclined plate 62 located at the bottom of the screen plate 61. The guide plate 55, screen plate 61 and inclined plate 62 are all designed with an inclined structure. A vibration motor 63 is fixedly installed at the bottom of the screen plate 61. The processing box 1 has discharge ports 64 located above the screen plate 61 and the inclined plate 62 on the left and right sides, respectively. By combining the inclined screen plate 61 of the screening component 6 with the vibration motor 63, the grading and screening of the crushed material is accelerated. The inclined plate 62 guides coarse and fine particles to be discharged from different discharge ports, realizing the integrated continuous operation of "crushing-magnetic separation-screening", which effectively improves the practicality and reliability of the device.
[0032] The crushing chamber 2 is internally equipped with a crushing mechanism 7 extending to its outer side. The crushing mechanism 7 includes two drive shafts 71, which are rotatably mounted between the inner walls of the crushing chamber 2 and extend to its outer side. Crushing rollers 72 located inside the crushing chamber 2 are fixedly installed on the outer side of the drive shafts 71. A control motor 73 is fixedly installed on the rear side of the crushing chamber 2. The output shaft of the control motor 73 is fixedly connected to the drive shaft 71 on the left side. Several interleaved crushing teeth 74 are fixedly installed on the outer side of each of the two crushing rollers 72 to increase the contact area with the waste and the squeezing and shearing force. A gearbox 75 located on the outer side of the drive shafts 71 is fixedly installed on the front side of the crushing chamber 2. This wood waste recycling device enhances the crushing effect on wood waste by setting the interleaved crushing teeth 74 of the crushing mechanism 7. Combined with the independent drive of the drive motor 42 and the control motor 73, the crushing efficiency is guaranteed.
[0033] The working process of this utility model:
[0034] Step 1: After the wood waste is fed into the crushing box 2 from the feed hopper 3, the control motor 73 is started and the left drive shaft 71 is driven to rotate through the gear box 75. The right drive shaft 71 is driven to rotate synchronously through the gear transmission. The crushing teeth 74 on the outer side of the two crushing rollers 72 squeeze and shear the waste, crushing the wood waste into smaller particles.
[0035] Step two: The crushed particles fall into the magnetic conveying mechanism 4 inside the processing box 1. The drive motor 42 drives the transmission roller 41 to rotate, which in turn drives the conveyor belt 43 to circulate. The magnetic blocks 44, which are evenly distributed on the outer side of the conveyor belt 43, adsorb ferromagnetic impurities (such as iron nails and steel sheets) in the crushed material during the movement, thus separating the ferromagnetic impurities from the non-magnetic crushed material. When the magnetic blocks 44 that adsorb impurities move to the bottom of the conveyor belt 43, the scraper 53 on the support block 52 comes into contact with the bottom of the magnetic blocks 44, scraping the impurities into the collection box 54 below for temporary storage. The non-magnetic crushed material that is not adsorbed is guided down to the screening component 6 by the guide plate 55.
[0036] Step 3: Non-magnetic fragments fall onto the inclined screen plate 61. The vibrating motor 63 drives the screen plate 61 to vibrate at high frequency, causing the fragments to be classified according to particle size. Fine particles fall through the screen holes and are guided by the inclined plate 62 before being discharged from one side outlet 64. Coarse particles slide down the inclined surface of the screen plate 61 to the other side outlet 64 and are discharged, thus completing the classification and collection of fragments of different particle sizes.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
