Description

Technical Field

[0001] This utility model relates to the field of fiberboard production equipment technology, and in particular to a wood chipping device for fiberboard production. Background Technology

[0002] Fiberboard, also known as medium-density fiberboard, is a type of engineered wood product made from wood fibers or other plant fibers bonded together with urea-formaldehyde resin or other suitable adhesives. Adhesives and / or additives may be applied during the manufacturing process. Fiberboard has advantages such as uniform texture, small difference in longitudinal and transverse strength, and resistance to cracking, making it widely used. Manufacturing 1 cubic meter of fiberboard requires approximately 2.5 to 3 cubic meters of timber, which can replace 3 cubic meters of sawn timber or 5 cubic meters of logs. Developing fiberboard production is an effective way to comprehensively utilize timber resources.

[0003] For example, patent document CN219768562U discloses a wood chipping device for fiberboard production. In use, wood is placed in the feed inlet, and the motor is started. The motor shaft rotates, driving a pulley and a rotating shaft, causing the blades to rotate at high speed and chip the wood. The wood chips fall onto the top of a filter screen under gravity. Simultaneously, the motor shaft rotates, driving a cam and a moving plate, causing a striking plate to beat the filter screen. The filter screen vibrates, separating the wood chips and sawdust; the wood chips move to the left and are discharged, while the sawdust falls into a collection box.

[0004] In current patents, most feed inlet designs lack anti-clogging mechanisms, which affects the continuity of operations. Furthermore, the relatively simple structure of the cutting disc results in lower cutting efficiency. Utility Model Content

The cutter 602 is installed on the steps of the layered cutter holder 601.

[0033] Working principle: First, the wood is placed on the first conveyor belt 305. The second motor 304 starts and drives the transmission shaft assembly, which includes a rotating shaft 301 and a second pulley 302. The rotation of the rotating shaft 301 drives the second pulley 302 to rotate. A second V-belt 303 is fitted onto the second pulley 302. When one of the second pulleys 302 rotates, the second V-belt 303 drives the other second pulley 302 to rotate. The rotation of the other second pulley 302 drives the other rotating shaft 301 to rotate. The first conveyor belt 305 is fitted onto the rotating shaft 301. When both rotating shafts 301 rotate, the first conveyor belt 305 also rotates synchronously, carrying the wood into the... Inside the crushing and feeding mechanism, motor 202 starts and drives the feeding component to rotate. The feeding component includes a crushing roller 203 and a first pulley 208. Motor 202 rotates first, driving the first pulley 208 to rotate. A first V-belt 206 is installed on the first pulley 208. Through the first V-belt 206, the two feeding components will rotate simultaneously. When the wood comes into contact with the crushing roller 203, it will trigger the pressure sensor on the crushing roller 203. Then, the hydraulic rod 205 will slide axially within the hydraulic cylinder 204 to adjust the angle of the extrusion shell 207. After adjusting the angle of the extrusion shell 207, the distance between the crushing roller 203 and the wood can be adjusted. If the wood is large, it can be crushed, thus completing the feeding process. The wood then enters the chipping mechanism. Motor 3 (502) starts, driving transmission rod 1 (503) to rotate. Transmission rod 1 (503) rotates, causing bevel gear 2 (504) and turntable 505 to rotate. Turntable 505 is equipped with an adjusting cutter head. When turntable 505 rotates, the adjusting cutter head begins to cut the wood. Bevel gear 2 (504) and bevel gear 3 (506) mesh with each other. When bevel gear 2 (504) rotates, it drives bevel gear 3 (506) to rotate. Bevel gear 3 (506) rotates, driving transmission rod 2 (508) to rotate. Transmission rod 2 (508) rotates, driving bevel gear 4 (507) to rotate. Bevel gear 4 (507) meshes with bevel gear 1 (406). When bevel gear 4 (507) rotates, bevel gear 1 (406) also rotates. Rotation of 406 drives rotation of shaft 3 405, which in turn drives rotation of third pulley 403. Rotation of third pulley 403 drives rotation of third V-belt 404, which in turn drives rotation of another third pulley 403. Rotation of another third pulley 403 drives rotation of shaft 2 401. Shaft 2 401 is fitted with a second conveyor belt 407. Rotation of shaft 2 401 drives rotation of second conveyor belt 407. When the adjusting cutter head starts cutting, the bottom cutter 602 starts cutting the wood first. When cutting hard wood, cutter 602 will retract under the action of spring 603, which plays a buffering role, protecting cutter 602 and extending its service life.
