Description

Technical Field

[0001] This utility model relates to the technical field of particleboard edge strip recycling devices, and in particular to an automatic particleboard edge strip recycling mechanism. Background Technology

[0002] Particleboard, a type of engineered wood product made from wood chips or other lignocellulosic materials bonded together with adhesives under heat and pressure, is widely used in furniture manufacturing, building decoration, and packaging due to its uniform structure, good processing performance, and moderate price. With the continuous development of the furniture and construction industries, market demand for particleboard has been increasing year by year, driving the continuous expansion of particleboard production. In the production process, particleboard efficiently utilizes wood processing residues, achieving both secondary resource development and aligning with the development concept of a circular economy. It has become one of the products with high resource utilization rates in the wood processing industry, and its stable production and supply play a vital supporting role in the healthy development of related industries. Therefore, an automatic recycling mechanism for particleboard edge strips is particularly needed.

[0003] However, in the current particleboard production process, a large number of edge strips are generated during use. These edge strips are traditionally discarded or burned as waste, which not only causes a serious waste of wood resources, but also pollutes the environment due to the harmful gases produced by burning, and increases storage costs due to the space occupied by stacking. At the same time, the manual sorting and handling of edge strips is inefficient, labor-intensive, and makes it difficult to achieve accurate recycling and reuse of edge strips, resulting in an extremely low recycling rate. This is neither in line with the concept of green production, nor can it create additional value for enterprises, thus affecting the efficiency of particleboard edge strip recycling.

[0004] To address the aforementioned issues, a search revealed that patent CN221818956U discloses an environmentally friendly particleboard waste recycling device. The patent describes "an environmentally friendly particleboard waste recycling device, comprising a housing, an inlet located on one side of the top of the housing, a first guide plate located below the inlet, a micro vibrator located below the first guide plate, a water tank located inside the housing, a crushing chamber located below the water tank, a collection assembly located below the crushing chamber, and a [missing information - likely a device or component] located on one side of the collection assembly." The device includes a compression assembly with a recycling pool below it, a clamping assembly on the outer surface of the housing, and casters at the four corners of the lower surface. Uniform material feeding is achieved through inclined guide plates and micro-vibrators. A crushing roller crushes the waste material, and a spray nozzle atomizes and reduces dust to prevent dust dispersion. Waste collection, compression, and drainage are completed using a collection and compression assembly. Water is recycled through a water pump and storage tank. The clamping assembly can accommodate and fix water pipes of different sizes, and the casters enhance the device's mobility. However, this device lacks an automatic reprocessing mechanism for large, unqualified particles after screening, and it does not incorporate vibration displacement compensation design for the vibrating equipment and other components. Furthermore, it lacks a dedicated design for fine-grained grading, storage, and retrieval structures for screened particles.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution: an automatic recycling mechanism for particleboard edge strips, including a vibrating screen bed 1, a screen 2 fixedly connected to one end of the vibrating screen bed 1, a base plate 3 fixedly connected to the other end of the vibrating screen bed 1, a connecting plate 4 fixedly connected to one side of the screen 2, a guide chute 5 fixedly connected to one side of the connecting plate 4, a first elastic cloth sleeve 6 fixedly connected to one side of the guide chute 5, a first feed inlet 7 fixedly connected to one end of the first elastic cloth sleeve 6, a screw conveyor 8 fixedly connected to one end of the first feed inlet 7, a return port 9 provided on one side of the screw conveyor 8, and a return port 9 on one side of the return port 9. A second elastic cloth sleeve 10 is fixedly connected, and a second feed inlet 11 is fixedly connected to one end of the second elastic cloth sleeve 10. A hammer crusher 12 is fixedly connected to one end of the second feed inlet 11. A guide plate 13 is fixedly connected to one end of the lower surface of the hammer crusher 12. A fixed bracket 16 is fixedly connected to one side of the hammer crusher 12. During use, particleboard strips can be fed into the hammer crusher 12 through the inlet of the second feed inlet 11. At the same time, large particles conveyed by the screw conveyor 8 also enter the return channel of the second feed inlet 11 through the second elastic cloth sleeve 10 and the return inlet 9. Guided by the diversion baffle inside the second feed inlet 11, the material enters the crushing chamber. After being crushed by the hammer crusher 12, the material slides onto the vibrating screen bed 1 through the inclined guide plate 13. The vibrating screen bed 1 is not directly connected to the hammer crusher 12, but forms a material passage only through the guide plate 13. After the vibrating screen bed 1 is started, the chassis base of the vibrating screen bed 1 provides stable support, driving the screen 2 and the base plate 3 to vibrate synchronously. The screen 2 and the base plate 3 are both fixed to the vibrating screen bed 1 with bolts and can be disassembled independently. Qualified particles with a particle size smaller than the aperture of the screen 2 pass through the screen 2, while large particles with a particle size larger than the aperture of the screen 2 are vibrated. Under the action of dynamic thrust, it slides along the bottom plate 3, enters the inclined guide chute 5 through the connecting plate 4, and enters the independently fixed screw conveyor 8 through the first elastic cloth sleeve 6 and the first feed port 7. It is then transported to the return port 9, and then flows back to the hammer crusher 12 through the second elastic cloth sleeve 10 and the second feed port 11 for secondary crushing, forming a complete cycle. During the whole process, the screen 2 and the bottom plate 3 can be replaced and maintained by removing the bolts. The first elastic cloth sleeve 6, the second elastic cloth sleeve 10 and the third elastic cloth sleeve 14 serve as vibration displacement compensation components, effectively avoiding the problem of material spillage caused by equipment vibration.

[0023] Furthermore, a third elastic cloth cover 14 is fixedly connected to one end of the lower surface of the screen 2, and a storage compartment 15 is fixedly connected to one end of the third elastic cloth cover 14. During use, the material falls into the storage compartment 15 through the third elastic cloth cover 14, and the staff can retrieve the material by pulling out the drawer box on one side of the storage compartment 15.

[0024] Furthermore, the guide chute 5 is set at an inclination, and the vibrating screen bed 1 is fixedly connected to the fixed support 16. With the setting of the inclined guide chute 5, large particles can slide down naturally by gravity, reducing conveying resistance and avoiding material stagnation. The setting of the vibrating screen bed 1 and the fixed support 16 can enhance the overall stability of the vibrating screen bed 1 during operation and avoid displacement or shaking caused by vibration, which would affect the screening accuracy.

[0025] Furthermore, the screen 2 is fixedly connected to the vibrating screen bed 1 by bolts. The first elastic cloth sleeve 6 is made of nylon. The connection between the screen 2 and the vibrating screen bed 1 facilitates the quick disassembly and replacement of screens 2 with different apertures according to particle size requirements, improving the adaptability and ease of maintenance of the equipment. The first elastic cloth sleeve 6 made of nylon utilizes the elasticity and wear resistance of nylon to compensate for the displacement difference caused by vibration, extend the service life of the cloth sleeve, and effectively prevent material from falling at the connection point.

[0026] Furthermore, the vibrating screen bed 1 is fixedly connected to the storage bin 15, and the bottom plate 3 and the screen 2 are arranged in parallel. The arrangement of the vibrating screen bed 1 and the storage bin 15 ensures that the qualified particles below the screen 2 can fall accurately into the storage bin 15, avoiding particle scattering due to relative displacement between the two, thus improving collection efficiency. The arrangement of the bottom plate 3 and the screen 2 allows large particles to slide smoothly along the bottom plate 3 to the guide chute 5 under the action of vibration thrust, avoiding material accumulation or poor conveying due to angular deviation.

[0027] Furthermore, the guide plate 13 is set at an inclination. By setting the guide plate 13 at an inclination, the material crushed by the hammer crusher can be guided to slide naturally onto the vibrating screen bed 1 without additional power, saving energy and avoiding material accumulation at the outlet of the hammer crusher 12.

[0028] Furthermore, the base plate 3 is fixedly connected to the third elastic cloth sleeve 14. The arrangement of the base plate 3 and the third elastic cloth sleeve 14 ensures that the material on the base plate 3 that has not passed through the screen 2 can be smoothly conveyed through the third elastic cloth sleeve. At the same time, the elasticity of the cloth sleeve compensates for vibration displacement and prevents the material from falling off.

[0029] Working Principle: During the cutting process in particleboard production, a large amount of waste edge strips are generated. These strips are collected immediately by an edge strip recycling device, typically installed at the outlet of the particleboard cutting equipment. Through mechanical baffles or negative pressure adsorption, the strips are gathered and collected, preventing them from scattering, piling up, or being discarded as waste. This initial recycling provides the raw material basis for subsequent reuse. This step solves the resource waste problem caused by the direct discarding of edge strips in traditional production and is the starting point of the entire recycling process.

[0030] The edge strips collected by the edge trimming and recycling device are automatically conveyed via a belt conveyor. The input end of the belt conveyor connects to the discharge port of the edge trimming and recycling device, while the output end precisely connects to the second feed port of the hammer crusher. During belt conveying, the conveying speed is controlled by a speed-regulating motor to ensure that the edge strips enter the subsequent crushing stage evenly and continuously. This replaces the traditional manual handling method, reduces labor intensity, and prevents secondary scattering of edge strips during transportation, thereby improving the overall automation efficiency of the process.

[0031] The edge strips conveyed by the belt conveyor enter the hammer crusher 12 through the second feed inlet, initiating the recycling and crushing process. The hammer crusher 12 uses high-speed rotating hammers to impact and crush the edge strips, breaking the long strips into irregular particles. During this process, any "unqualified large particles" returned by the screw conveyor 8 will enter the crushing chamber together with the newly input edge strips under the guidance of the diversion baffle inside the second feed inlet 11, achieving mixed crushing and ensuring that all recycled edge strips are fully crushed, providing qualified pre-treated material for subsequent screening.

[0032] The crushed material slides down the inclined guide plate 13 onto the vibrating screen bed 1. After the vibrating screen bed 1 is started, the material is classified by high-frequency vibration: "qualified particles" with a particle size smaller than the aperture of the screen 2 pass through the screen 2 and enter the next stage; "unqualified large particles" with a particle size larger than the aperture of the screen 2 slide along the bottom plate 3 under the action of vibration thrust and enter the return channel.

[0033] Qualified particle storage: Qualified particles that pass through the screen 2 fall into the storage bin 15 through the third elastic cloth sleeve 14, completing the final recycling and storage of the edge strips, which can then be directly used for particleboard reprocessing.

[0034] Large particle circulation: Unqualified large particles enter the inclined guide chute 5 through the connecting plate 4, and then enter the screw conveyor 8 through the first elastic cloth sleeve 6 and the first feed port 7. They then flow back to the hammer crusher 12 through the return port 9 and the second elastic cloth sleeve 10 to participate in the "recycling and crushing" process again, forming a closed loop of "crushing-screening-returning-re-crushing" to ensure that all edge strips can be fully utilized without waste.

[0035] Through a complete process design of "edge trimming and recycling → belt conveyor → recycling and crushing → screening and sorting → storage and recycling", this mechanism realizes the automated recycling of particleboard edge strips from generation to secondary use: it solves the problem of low edge strip collection efficiency by combining edge trimming and recycling and belt conveyor, and ensures the full crushing and utilization of edge strips through recycling, crushing and recycling mechanism. Finally, the standardized storage of recycled materials is achieved through the storage stage, which completely solves the problems of resource waste, environmental pollution and low efficiency in traditional edge strip processing, and greatly improves the efficiency of particleboard edge strip recycling.

[0036] 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.
