[0002] With increasing environmental awareness and growing demand for resource recycling, the engineered wood products industry is placing greater emphasis on the recycling and reuse of wood waste such as wood strips. After being crushed and cut, waste wood strips can be used as raw materials to manufacture engineered wood products, biomass fuels, and other products, achieving sustainable resource utilization. With the rapid development of the engineered wood products industry, the market demand for waste wood strip crushing and cutting equipment is constantly increasing. Especially in industries such as furniture manufacturing, building decoration, and papermaking, the demand for recycling and reusing waste wood strips is significant, providing ample room for the market development of related equipment. To meet the needs of different users, the variety of waste wood strip crushing and cutting equipment is becoming increasingly diversified.

[0003] In traditional wood processing, manual processing of waste wood strips accounts for a significant portion of the work. However, this method is extremely inefficient and falls short of the demands of large-scale production.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figures 1 to 4This utility model provides a waste wood strip crushing and cutting device for artificial production, which includes a box body 1. A feeding plate 2 is fixedly connected to one side of the box body 1, and a receiving port 3 is fixedly connected to the bottom of the other side of the box body 1. A cutting component for cutting waste wood strips is installed inside the box body 1, and a crushing component for crushing waste wood strips is installed below the cutting component. A cooling component for cooling the cutting component and the crushing component is installed on the box body 1. A discharge port 12 is opened at the bottom of the box body 1, and a screening component is fixedly installed above the discharge port 12.

[0022] The housing 1 forms the main frame, with a feeding plate 2 fixedly connected to one side for feeding materials to be processed. After entering the housing 1 via the feeding plate 2, the material first reaches the area where the cutting component is located. The cutting component performs preliminary cutting, breaking larger pieces into smaller ones to prepare for subsequent crushing operations. A crushing component is fixedly connected below the cutting component. The cut material falls directly into the working range of the crushing component, which further crushes the smaller pieces to achieve a finer particle size to meet the particle size requirements of different processes. Since the cutting and crushing processes generate a large amount of heat, a cooling component is fixedly connected between the cutting and crushing components to prevent damage to the equipment due to high temperatures. The cooling component uses a specific internal structure to circulate cooling water, carrying away the heat generated by the cutting and crushing components during operation and ensuring stable operation of the equipment at a suitable temperature.

[0023] The cutting assembly includes a second rotating shaft 22, which is rotatably mounted on the housing 1. Two sets of rings 17 are sleeved on the outer wall of the second rotating shaft 22, and several cutting blades 16 are fixedly installed between the two sets of rings 17. A first transmission wheel 4 is sleeved on one end of the second rotating shaft 22.

[0024] In the cutting assembly, a ring 17 is installed on the outer wall of the second rotating shaft 22 by a sleeve connection. A cutting blade 16 is fixedly welded to the inner wall of the ring 17. When the second rotating shaft 22 rotates, the cutting blade 16 rotates synchronously with the ring 17 to form a cutting action. A first transmission wheel 4 is installed on one end of the second rotating shaft 22 by a sleeve connection. The first transmission wheel 4 rotates under the action of the transmission belt 5, thereby driving the second rotating shaft 22 and the cutting blade 16 to rotate synchronously to achieve the cutting function.

[0025] The crushing assembly includes two sets of first rotating shafts 21, which are rotatably mounted on the housing 1. Crushing discs 18 are sleeved on the outer wall of the first rotating shafts 21. Two sets of gears 14 are sleeved on one end of the first rotating shafts 21, and the two sets of gears 14 mesh with each other. A first motor 9 is fixedly connected to the end of the first rotating shafts 21. The first motor 9 is fixed to the housing 1. A second transmission wheel 6 is sleeved on the left side of the first motor 9. A transmission belt 5 is tensioned and sleeved between the second transmission wheel 6 and the first transmission wheel 4.

[0026] The crushing assembly includes two sets of first rotating shafts 21. Each set of first rotating shafts 21 has a crushing disc 18 installed on its outer periphery via a sleeve connection. Two sets of gears 14 are installed at one end of the first rotating shaft 21 via a sleeve connection. These two sets of gears 14 mesh with each other to form a gear 14 transmission mechanism, enabling the two sets of first rotating shafts 21 to rotate synchronously and in opposite directions, thereby enhancing the crushing effect. A first motor 9 is fixedly connected to the end of the first rotating shaft 21. The first motor 9 serves as a power source, driving the first rotating shaft 21 and the crushing disc 18 to rotate. When the first rotating shaft 21 rotates, the crushing disc 18 rotates accordingly, crushing the material. A second transmission wheel 6 is installed on the left side of the first motor 9 via a sleeve connection. A transmission belt 5 is tensioned and sleeved between the second transmission wheel 6 and the first transmission wheel 4 in the external cutting assembly. Through the transmission action of the transmission belt 5, the first motor 9 indirectly drives the second rotating shaft 22 in the cutting assembly, forming a power transmission chain.

[0027] The cooling assembly includes an interconnecting pipe 13, which is connected to the first rotating shaft 21 and the second rotating shaft 22. Both the first rotating shaft 21 and the second rotating shaft 22 have cooling chambers 20 inside. The end of the second rotating shaft 22 near the first motor 9 is movably connected to a rotary joint 7, and the end of the rotary joint 7 is fixedly connected to a water outlet pipe 8. The end of the first rotating shaft 21 near the first motor 9 is fixedly connected to a water inlet pipe 10.

[0028] Interconnecting pipes 13 are connected to the first rotating shaft 21 and the second rotating shaft 22, respectively, forming a basic channel network for cooling water flow. Both the first and second rotating shafts 21 and 22 have cooling chambers 20 inside, providing space for cooling water to directly contact the shafts and remove heat. An external cooling circulation device is used; cooling water enters from the inlet pipe 10 fixedly connected to the side of the first rotating shaft 21 near the first motor 9, flows through the cooling chamber 20 inside the first rotating shaft 21, absorbing the heat generated by the first rotating shaft 21 during operation, and then flows through the interconnecting pipes 13 into the cooling chamber 20 inside the second rotating shaft 22, continuing to absorb heat from the second rotating shaft 22. On the side of the second rotating shaft 22 near the first motor 9, since the second rotating shaft 22 is movably connected to the rotary joint 7, the cooling water can smoothly pass through the rotary joint 7 and finally exit from the outlet pipe 8 fixedly connected to the end of the rotary joint 7, completing the entire cooling cycle. This cooling component, through the circulation of cooling water, effectively reduces the temperature of the first and second rotating shafts 21 and 22 during operation, ensuring stable operation of the equipment.

[0029] The sieving assembly includes a sieve disc 19, which is hinged to a housing 1. A rotating shaft is mounted on the housing 1. A vibration point is fixedly connected to the middle of the rotating shaft. Eccentric blocks 15 are sleeved and mounted at both ends of the rotating shaft. A second motor 11 is fixedly connected to the end of the rotating shaft.

[0030] A second motor 11 is fixedly connected to the end of the rotating shaft. The second motor 11 serves as a power source to drive the shaft to rotate. When the second motor 11 starts, it drives the shaft to rotate. The eccentric block 15 generates uneven centrifugal force due to rotation, causing the shaft to vibrate strongly, which in turn drives the screen plate 19 to vibrate. Under the action of vibration, particles smaller than the screen holes on the screen plate 19 fall through the screen holes, thus achieving the separation of materials through sieving.

[0031] The upper surface of the sieve plate 19 has multiple holes, and the inside of the box 1 is equipped with support columns to support the sieve plate 19.

[0032] The multiple holes on the sieve plate 19 can effectively screen wood chips of different sizes. Unqualified chips will fall into the receiving port 3. The support column can effectively support the sieving component.

[0033] Working principle: The box body 1 is the main frame, with a feeding plate 2 fixedly connected to one side for feeding the material to be processed. After the material enters the box body 1 through the feeding plate 2, it first reaches the area where the cutting component is located. The cutting component performs preliminary cutting processing on the material. A ring 17 is installed on the outer wall of the second rotating shaft 22 in the cutting component through a sleeve connection. A cutting blade 16 is fixedly welded to the inner wall of the ring 17. When the second rotating shaft 22 rotates, the cutting blade 16 rotates synchronously with the ring 17, forming a cutting action. One end of the second rotating shaft 22 is installed through a sleeve connection. Equipped with a first drive wheel 4, which rotates under the action of a drive belt 5, thereby driving the second rotating shaft 22 and the cutting blade 16 to rotate synchronously, thus achieving the cutting function; a crushing component is fixedly connected below the cutting component, and the cut material falls directly into the working range of the crushing component, which further crushes the small pieces of material to achieve a finer degree, in order to meet the particle size requirements of different processes. The crushing component includes two sets of first rotating shafts 21, and each set of first rotating shafts 21 has a crushing disc blade 18 installed on its outer periphery through a sleeve connection. Two sets of gears 14 are installed at one end of the first rotating shaft 21 by a sleeve connection. These two sets of gears 14 mesh with each other to form a gear 14 transmission mechanism, which enables the two sets of first rotating shafts 21 to rotate synchronously and in opposite directions, thereby enhancing the crushing effect. The end of the first rotating shaft 21 is fixedly connected to the first motor 9, which serves as a power source to drive the first rotating shaft 21 and the crushing disc 18 to rotate. When the first rotating shaft 21 rotates, the crushing disc 18 rotates accordingly to crush the material. The left side of the first motor 9 is equipped with a second transmission wheel 6 by a sleeve connection. A transmission belt 5 is tensioned and sleeved between the second transmission wheel 6 and the first transmission wheel 4 in the external cutting assembly. Through the transmission action of the transmission belt 5, the first motor 9 indirectly drives the second rotating shaft 22 in the cutting assembly, forming a power transmission chain. Since the cutting and crushing process generates a lot of heat, a cooling assembly is fixedly connected between the cutting assembly and the crushing assembly to prevent the equipment from being damaged by high temperature. The interconnecting pipe 13 is connected to the first rotating shaft 21 and the second rotating shaft 22 respectively, forming a basic channel network for cooling water flow. Both the first rotating shaft 21 and the second rotating shaft 22 have cooling chambers 20 inside. These pipes provide space for cooling water to directly contact the rotating shafts and remove heat. An external cooling circulation device is connected. Cooling water enters from the inlet pipe 10 fixedly connected to the side of the first rotating shaft 21 near the first motor 9, flows through the cooling chamber 20 inside the first rotating shaft 21, and absorbs the heat generated by the operation of the first rotating shaft 21. Subsequently, the cooling water flows into the cooling chamber 20 inside the second rotating shaft 22 through the interconnecting pipe 13, continuing to absorb heat from the second rotating shaft 22. On the side of the second rotating shaft 22 near the first motor 9, because the second rotating shaft 22 is movably connected to the rotary joint 7, the cooling water can smoothly pass through the rotary joint 7 and finally be discharged from the outlet pipe 8 fixedly connected to the end of the rotary joint 7, completing the entire cooling cycle.This cooling component effectively reduces the temperature of the first rotating shaft 21 and the second rotating shaft 22 during operation through the circulation of cooling water, ensuring the stable operation of the equipment. The end of the shaft is fixedly connected to the second motor 11, which serves as the power source to drive the shaft to rotate. When the second motor 11 starts, it drives the shaft to rotate. The eccentric block 15 generates uneven centrifugal force due to rotation, causing the shaft to vibrate strongly, which in turn drives the screen plate 19 to vibrate. Under the action of vibration, particles smaller than the screen holes on the screen plate 19 fall through the screen holes, realizing the sieving and separation of materials.
