Description

Technical Field

[0001] This utility model relates to the field of pretreatment equipment technology, specifically to a pretreatment equipment for wood fibers. Background Technology

[0002] Wood fiber is an organic, flocculent fibrous material obtained from natural, renewable wood through chemical treatment and mechanical processing. It is widely used in wood-plastic composites, which are made of wood fiber and waste plastics. The quality of wood fiber drying directly affects the mechanical properties of wood-plastic composites. Under high-temperature compounding conditions, if the moisture content of wood fiber is too high, the fiber surface will vaporize rapidly, forming weak boundary layers such as voids at the interface of the composite material. This can lead to micropores or internal stress defects in the composite material, affecting its performance. Therefore, wood fiberboard needs to be thoroughly dried before wood fiber is compounded with thermoplastic plastics.

[0003] For example, Chinese utility model patent application number 202221980188.7 discloses a pretreatment device for wood fiber, which includes: a base, a housing fixedly connected to the upper end face of the base, a top plate fixedly connected to the upper end face of the housing, a feed inlet on the front end face of the housing, a U-shaped feed plate fixedly connected to the housing within the feed inlet, a rectangular plate fixedly connected to the front end face of the housing, an electric telescopic rod fixedly connected to the lower end face of the rectangular plate, a U-shaped mounting plate fixedly connected to the telescopic end of the electric telescopic rod, and a pusher roller rotatably connected between the two vertical sections of the U-shaped mounting plate. Through this structure, the wood fiberboard is dried using two rows of evenly distributed drying conveyor rollers, preventing the wood fiberboard from having excessively high moisture content after processing into wood fibers. This prevents the formation of weak boundary layers such as voids at the composite material interface, which could lead to micropores or internal stress defects in the composite material, affecting its performance.

[0004] However, during the use of the aforementioned pretreatment equipment, the position of the material on the conveyor belt is not easily controlled, and the wood fibers may deviate or slip due to vibration or uneven accumulation, making it difficult to ensure uniform material distribution and affecting the drying effect. Therefore, those skilled in the art have provided a pretreatment device for wood fibers to solve the problems mentioned in the background art. Utility Model Content

[0034] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0035] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown. A pretreatment device for wood fiber includes a conveyor belt 1, mounting brackets 2 are installed on both sides of the conveyor belt 1, a support base 3 is fixed at the bottom of the mounting brackets 2, a pretreatment drying mechanism body 4 is provided on the top of the conveyor belt 1, a shielding curtain 5 is installed at the bottom of the pretreatment drying mechanism body 4, an adjustable limiting mechanism 6 is provided on the outside of the mounting brackets 2, and a fine-tuning mechanism 7 is connected to the outside of the adjustable limiting mechanism 6;

[0036] The adjustable limiting mechanism 6 includes a fixed housing 61, a support bracket 62 fixed to the bottom of the fixed housing 61, a servo motor 63 installed on the inner bottom wall of the fixed housing 61, an eccentric wheel 64 fixed to the outer side of the output shaft of the servo motor 63, a return spring 65 provided on one side inner wall of the fixed housing 61, a movable plate 66 connected to one end of the return spring 65, an anti-detachment slider 67 fixed to one side of the movable plate 66, and a movable rod 68 fixed to the outer side of the movable plate 66. The support bracket 62 and the mounting bracket 2 are fixedly connected. The servo motor 63 and the fixed housing 61 are fixed together by bolts to ensure the stability of the fixed housing 61 installation structure. A limiting hole is opened inside the fixed housing 61. The size of the limiting hole is adapted to the size of the movable rod 68 to ensure that the movable rod 68 can move normally in the horizontal direction. A sliding groove is opened on one side inner wall of the fixed housing 61. The anti-detachment slider 67 is slidably connected to the fixed housing 61 through the sliding groove. One end of the return spring 65 is fixedly connected to the movable plate 66, and one side of the movable plate 66 is in contact with the outer side of the eccentric wheel 64.

[0037] The fine-tuning mechanism 7 includes a mounting sleeve 71, a mounting bracket 72 fixed to the bottom of the mounting sleeve 71, a limit pad 73 installed at one end of the mounting bracket 72, a limit plate 74 fixed at one end of the movable rod 68, a first threaded sleeve 75 threadedly connected to the outer side of the movable rod 68, a second threaded sleeve 76 threadedly connected to the outer side of the movable rod 68, and the mounting sleeve 71 is movably sleeved on the outer side of the movable rod 68. The outer sides of the first threaded sleeve 75 and the second threaded sleeve 76 are both provided with anti-slip textures.

[0038] In this embodiment, when the wood fiber material requiring drying pretreatment is placed on the conveyor belt 1, it is transported to the pretreatment drying mechanism body 4 for drying pretreatment. During the conveying process, the servo motor 63 is activated, causing the output shaft of the servo motor 63 to drive the eccentric wheel 64 to rotate. This allows the eccentric wheel 64 to push the movable plate 66 and the movable rod 68 to move, thereby adjusting the position of the fine-tuning mechanism 7. During the adjustment process, the anti-detachment slider 67 provides guidance and limitation. By adjusting the width of the limitation, it can adapt to the size or processing volume of different batches of wood fiber, meeting the needs of multi-variety production. Moreover, it can effectively constrain the position of the material on the conveyor belt 1, preventing the wood fiber from slipping or deviating due to vibration or uneven accumulation. This ensures uniform material distribution and improves the drying pretreatment effect. The fine-tuning mechanism 7 allows for adjustments to the fixed position of the limiting pad 73. By rotating the second threaded sleeve 76 and the first threaded sleeve 75, the corresponding surfaces of the second threaded sleeve 76 and the first threaded sleeve 75 are moved away from the mounting sleeve 71. The mounting sleeve 71 is then moved to the outside of the movable rod 68, and the limiting pad 73 is moved simultaneously via the assembly bracket 72. After the limiting pad 73 reaches the appropriate position, the first threaded sleeve 75 and the second threaded sleeve 76 can be rotated again, ensuring their corresponding surfaces are tightly against the mounting sleeve 71. This facilitates the adjustment and locking of the mounting sleeve 71's position, ensuring uniform material distribution on the conveyor belt 1.

[0039] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
