Description

Technical Field

[0001] This utility model relates to the technical field of particleboard production equipment, specifically to a particleboard raw material impurity removal device. Background Technology

[0002] Particleboard, a common type of wood-based engineered wood product, is made by processing raw wood into shavings through cutting, debarking, and chipping, followed by gluing, laying, and hot pressing. However, during the harvesting, transportation, and storage of raw wood, impurities such as soil, sand, and bark debris often adhere to the surface of the wood.

[0003] In existing production processes, although most of the bark can be removed during the debarking process, the following problems still exist: 1. Fine dirt and gravel remain on the surface of the debarked wood segments, especially in humid environments, where dirt easily adheres to the wood surface. In traditional processes, such impurities need to be treated a second time after chipping by vibrating sieves or air classifiers. However, the shavings after chipping have a complex shape and increased surface area, resulting in a tight mixture of impurities and wood fibers, leading to low separation efficiency (usually only 60%-70% of impurities can be removed), and the screen is prone to clogging, requiring frequent cleaning; 2. Impurities that are not removed (such as dirt) will be mixed into the gluing process, reducing the effective adhesion area of ​​the adhesive, resulting in a decline in board quality, and even requiring rework, increasing production costs.

[0004] Therefore, this application provides a particleboard raw material impurity removal device to solve the above-mentioned problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a particleboard raw material impurity removal device. It can support the cut and peeled wood segments and drive the wood segments to rotate. It can also use high-pressure airflow to directionally peel off impurities on the surface of the wood segments during the rotation process, so as to avoid impurities from being mixed into the chipping process, thereby reducing the subsequent screening pressure, improving the cleanliness of wood shavings and the quality of finished board products, while reducing overall energy consumption and production costs. It can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a particleboard raw material impurity removal device, comprising two symmetrically arranged connecting plates, which are connected by two rotatably arranged shafts, and the shafts are provided with evenly distributed drive wheels.

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.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a particleboard raw material impurity removal device, including two symmetrically arranged connecting plates 1, which are connected by two rotatably arranged shafts 2. The shafts 2 are equipped with evenly distributed drive wheels 21. One of the connecting plates 1 is equipped with a drive component to drive the shaft 2 to rotate. Support frames 4 are installed at both ends of one shaft 2. The upper surface of the support frame 4 corresponding to the other shaft 2 is equipped with a flipping component. The flipping component drives one shaft 2 to rotate, so that the shaft 2 rotates around the central axis of the other shaft 2, thereby performing the wood segment cutting operation. A collection hopper 6 is arranged between the two support frames 4. The collection hopper 6 is equipped with two symmetrically arranged air knives 7. The air knives 7 are equipped with air pipes 71 connected to an external air pump. The external air pump delivers high-pressure air to the air knives 7 through the air pipes 71. Under the action of the two air knives 7, the high-pressure air removes surface impurities from the wood segments.

[0019] Furthermore, the flipping component includes a cylinder 5 rotatably mounted on the support frame 4. A connecting seat 51 is rotatably mounted on the top of the cylinder 5, and the connecting seat 51 is rotatably connected to the rotating shaft 2. After cleaning, the cylinder 5 is controlled to extend, and the cylinder 5 drives the corresponding rotating shaft 2 to rotate around the central axis of another rotating shaft 2 through the connecting seat 51, thereby pushing the wood segment onto the conveying equipment for conveying, in preparation for subsequent wood shavings.

[0020] Furthermore, the bottom of the collecting hopper 6 is provided with a negative pressure pipe 61 connected to an external negative pressure device. The external negative pressure device generates negative pressure inside the collecting hopper 6 through the negative pressure pipe 61. After the air knife 7 removes impurities from the wood section, the impurities are affected by the negative pressure and enter the front part of the collecting hopper 6, and are extracted and collected through the external negative pressure pipe 61.

[0021] Furthermore, the rotating shaft 2 is provided with two symmetrically arranged baffles 22, and the drive wheel 21 is located between the two baffles 22.

[0022] Furthermore, the driving component includes a motor 3 mounted on the connecting plate 1. The output shaft of the motor 3 is provided with a main pulley 31, and the shaft 2 is provided with a secondary pulley 23 at the corresponding position of the main pulley 31. The main pulley 31 and the secondary pulley 23 are connected by a belt 32. The motor 3 drives the main pulley 31 to rotate, and the main pulley 31 drives the secondary pulley 23 to rotate through the belt 32. The secondary pulley 23 drives the shaft 2 and the drive wheel 21 to rotate. During the rotation of the drive wheel 21, the wooden segment rotates on the two shafts 2.

[0023] The motor 3 used in this utility model is a common electrical device in the prior art. Its working method and circuit structure are well known technologies and will not be described in detail here. The motor 3 is electrically connected to an external switch.

[0024] When using:

[0025] The equipment is arranged between the wood cutting and peeling conveyor equipment. The wood cutting and peeling equipment conveys the wood to the two rotating shafts 2 via the external conveyor equipment.

[0026] Motor 3 drives the main pulley 31 to rotate, and the main pulley 31 drives the auxiliary pulley 23 to rotate via belt 32. The auxiliary pulley 23 drives the rotating shaft 2 and the drive wheel 21 to rotate. During the rotation of the drive wheel 21, the wooden segment rotates on the two rotating shafts 2.

[0027] An external air pump delivers high-pressure air to the air knife 7 through the air pipe 71. Under the action of the two air knives 7, the high-pressure air removes impurities from the surface of the wood segment.

[0028] The external negative pressure device generates negative pressure inside the collection hopper 6 through the negative pressure pipe 61. After the air knife 7 removes impurities from the wood section, the impurities are affected by the negative pressure and enter the middle part of the collection hopper 6, and are extracted and collected through the external negative pressure pipe 61.

[0029] After cleaning, the control cylinder 5 extends, and the cylinder 5 drives the corresponding rotating shaft 2 to rotate around the central axis of another rotating shaft 2 through the connecting seat 51, thereby pushing the wood segment onto the conveying equipment for conveying, in preparation for subsequent wood shavings.

[0030] This invention can support and rotate the cut and peeled wood segments. It can also use high-pressure airflow to directionally peel off impurities from the surface of the wood segments during rotation, preventing impurities from entering the chipping process. This reduces the pressure of subsequent screening, improves the cleanliness of wood shavings and the quality of finished boards, and reduces overall energy consumption and production costs.
