[0040] Among them, the cutting device 1 is used to cut the wood into small pieces of lumber and transfer them to the aggregate bin 2 for storage. The cutting device 1 includes a first conveyor belt 1-1, a cross-cutting mechanism 1-2 and a longitudinal cutting mechanism 1-3 arranged on the first conveyor belt 1-1. The cross-cutting mechanism 1-2 and the longitudinal cutting mechanism 1-3 are arranged in sequence along the conveying direction of the first conveyor belt 1-1. The cross-cutting mechanism 1-2 is used to cut the wood into long strips, and the longitudinal cutting mechanism 1-3 is used to cut the long-strip wood into small pieces of lumber.

[0041] In this embodiment, the cross-cutting mechanism 1-2 includes a number of horizontal cutting slices 1-21 arranged longitudinally, a number of longitudinal cutting slices 1-22 arranged horizontally and a connecting frame 1-23; a number of the longitudinal cutting slices 1-22 and a number of the horizontal cutting slices 1-21 are connected to form a grid shape. The size of the grid is the length and height of the lumber. The cross-cutting mechanism 1-2 with different grid sizes can be replaced according to requirements to facilitate obtaining lumbers of different sizes. And a blade is formed by shrinking at one end of a number of the longitudinal cutting slices 1-22 and a number of the horizontal cutting slices 1-21 opposite to the conveying direction of the first conveyor belt 1-1, which is more convenient for cutting wood; the lower parts of the longitudinal cutting slices 1-22 located on both sides are respectively connected with the connecting frame 1-23, and the two connecting frames 1-23 are respectively connected with the first fixing platforms 1-4 on both sides of the first conveyor belt 1-1 through bolts.

[0042] In this embodiment, the longitudinal cutting mechanism 1-3 includes a fixing frame 1-31, a driving member 1-32 and a cutting knife 1-33; the fixing frame 1-31 is in an inverted "U" shape, and the lower parts of its vertical parts are respectively connected with the first fixing platforms 1-4 on both sides of the first conveyor belt 1-1, specifically through bolts. The lower part of its horizontal part is connected with the driving member 1-32, and the lower part of the driving member 1-32 is connected with the cutting knife 1-33, which is used to drive the cutting knife 1-33 to move up and down to cut the long-strip wood. Further, the driving member 1-32 is a cylinder, and the telescopic movement of the cylinder drives the cutting knife 1-33 to move up and down to cut the wood; the cutting frequency of the cutting knife 1-33 can be controlled by controlling the time interval of the telescopic movement of the cylinder and the movement speed of the first conveyor belt 1-1, and lumbers of different widths can be obtained according to needs.

[0043] In this embodiment, to enable the wood to be cut by the cross-cutting mechanism 1-2 and the longitudinal cutting mechanism 1-3 and ensure the smooth progress of cutting, the cutting device 1 further includes a first guide and a second guide connected to the first fixing platforms 1-4 on both sides of the first conveyor belt 1-1; the first guide is located between the head end of the first conveyor belt 1-1 and the front end of the cross-cutting mechanism 1-2, and the second guide is located between the rear end of the cross-cutting mechanism 1-2 and the tail end of the first conveyor belt 1-1; as Figure 4 shown.

[0044] The first guide comprises two symmetrically arranged guide plates 1-5, the two guide plates 1-5 are respectively connected to the fixed platform 1-4, specifically, the side walls thereof are connected to the fixed platform 1-4 via a plurality of "L"-shaped brackets, one end of the bracket is bolted to the fixed platform 1-4, and the other end is welded to the guide plate 1-5; the front end of the guide plate 1-5 extends toward the center line direction of the conveyor belt 1-1 to form an inclined surface, until the guide plate 1-5 is adapted to the front end of the transverse cutting mechanism 1-2 and extends toward the transverse cutting mechanism 1-2;

[0045] The second guide includes two symmetrically arranged guide plates 1-6, and the two guide plates 1-6 are respectively connected to the fixed platform 1-4, and specifically, the side walls thereof are also connected to the fixed platform 1-4 through a plurality of "L"-shaped brackets, one end of the bracket is bolted to the fixed platform 1-4, and the other end is welded to the guide plate 1-6; the rear end of the guide plate 1-6 extends toward the center line direction of the conveyor belt 1-1 to form an inclined surface, until the guide plate 1-6 is adapted to the rear end of the transverse cutting mechanism 1-2 and extends toward the transverse cutting mechanism 1-2.

[0046] The wood is located on a conveyor belt 1-1 and is transported by the conveyor belt 1-1. The guide plate 1-5 is used to limit the left and right directions of the wood so that the position of the wood corresponds to the grid formed by the longitudinal slices 1-22 and the horizontal slices 1-21. During the transportation process, the slices cut the wood into strips. The cut strips are partially stacked, and the rear end distance of the two guide plates 1-6 becomes larger. The stacked strips are scattered on the conveyor belt 1-1. The cylinder drives the cutter 1-33 to move up and down to cut the strips into wood blocks. The cut wood blocks are transported to the collecting box 2 along the conveyor belt 1-1.

[0047] The conveying end of the conveyor belt 1-1 is connected to the feed inlet of the collection box 2, and is used to convey the cut wood into the collection box 2. In order to facilitate the smooth entry of the wood into the collection box 2, the collection box 2 is provided with an inclined guide plate 2-1 and baffles 2-2 are provided on both sides of the guide plate 2-1. The lower end of the guide plate 2-1 corresponds to the feed inlet of the collection box 2, and the high end corresponds to the end of the conveyor belt 1-1. The baffle 2-2 prevents the wood from falling from both sides of the guide plate 2-1. Since the guide plate 2-1 is inclined, under the action of gravity, the wood on the conveyor belt 1-1 can fall directly into the collection box 2 without additional power; the guide plate 2-1 can be connected to the contact position of the collection box 2 by bolts, or it can be welded. The collection box 2 is provided with a box cover to ensure that the wood inside is clean.

[0048] The wood in the collection box 2 enters the cooking device 3 for cooking. In this embodiment, the cooking device 3 includes a conveying mechanism 1 3-1 and a cooking box 3-2; one end of the conveying mechanism 1 3-1 is connected to the discharge port of the collection box 2, and the other end corresponds to the feed port of the cooking box 3-2, and is used to convey the wood into the cooking box 3-2; a liquid outlet pipe 3-3 is provided on the side wall of the cooking box 3-2, and a discharge pipe 3-4 is provided at the bottom; the liquid outlet pipe 3-3 is used to discharge the liquid in the cooking box 3-2, and the discharge pipe 3-4 is used to discharge the cooked wood, and valves are provided on the liquid outlet pipe 3-3 and the discharge pipe 3-4; the bottom of the discharge pipe 3-4 of the cooking box 3-2 corresponds to the conveyor belt 2 3-5, and is used to discharge the wood onto the conveyor belt 2 3-5; the end of the conveyor belt 2 3-5 is connected to the feed port of the buffer box 4. Furthermore, three cooking boxes 3-2 and conveying mechanism 1 3-1 are provided, the liquid outlet pipes 3-3 of the three cooking boxes 3-2 are connected, and the bottom of the outlet pipe 3-4 corresponds to the conveyor belt 2 3-5. The cooking box 3-2 can be a commercially available cooking box 3-2, and chemical agents are injected into the cooking box 3-2 during cooking as needed to facilitate the smooth cooking work.

[0049] Furthermore, the conveying mechanism 3-1 includes a conveying pipe 3-11, an auger 3-12, and a conveying motor 3-13; the conveying pipe 3-11 is tilted, the conveying motor 3-13 is arranged on the top, the discharge trough 3-14 corresponding to the feed port of the cooking box 3-2 is arranged on the upper part, the auger 3-12 is arranged inside, and the rotating shaft of the auger 3-12 is coaxially connected with the output shaft of the conveying motor 3-13, and the lower part of the conveying pipe 3-11 is connected with the discharge port of the collection box 2. When conveying wood to the cooking box 3-2, the conveying motor 3-13 is started to drive the auger 3-12 to rotate, so that the wood in the collection box 2 is conveyed from low to high, and when the wood reaches the discharge trough 3-14, it falls from the feed port of the cooking box 3-2 to the inside due to gravity.

[0050] The cooked material falls from the discharge pipe 3-4 onto the conveyor belt 2 3-5 and is conveyed to the direction of the buffer box 4. The buffer box 4 is provided with an inclined guide plate 2 4-1, and baffles 2 4-2 are provided on both sides of the guide plate 2 4-1; the lower end of the guide plate 2 4-1 corresponds to the feed port of the buffer box 4, and the upper end corresponds to the end of the cooking device 3, that is, the upper end corresponds to the end of the conveyor belt 2 3-5. Baffles 2 4-2 prevent wood from falling from both sides of the guide plate 2 4-1. Since the guide plate 2 4-1 is inclined, under the action of gravity, the wood on the conveyor belt 2 3-5 can fall directly into the buffer box 4 without additional power; the guide plate 2 4-1 can be connected to the contact position of the buffer box 4 by bolts, or it can be welded. The buffer box 4 is provided with a box cover to ensure that the wood inside is clean.

[0051] The wood in the buffer box 4 is conveyed to the hot mill 5 for grinding to form wood fibers. A conveying mechanism 2 4-3 is provided between the buffer box 4 and the hot mill 5. One end of the conveying mechanism 2 4-3 is connected to the discharge port of the buffer box 4, and the other end corresponds to the feed port of the hot mill 5. The conveying mechanism 2 4-3 adopts the same structure as the conveying mechanism 1 3-1, that is, it also includes a conveying pipe, an auger, and a conveying motor; the conveying pipe is inclined, the top of which is provided with the conveying motor, the upper part is provided with a discharge trough corresponding to the feed port of the hot mill 5, the inside is provided with the auger, and the rotating shaft of the auger is coaxially connected with the output shaft of the conveying motor, and the lower part of the conveying pipe is connected to the discharge port of the buffer box 4. The hot mill 5 in this embodiment can be a hot mill 5 that can be purchased on the market.

[0052] Through the above structure, the cutting, cooking and grinding processes of wood are completed to obtain wood fibers for papermaking. The whole structure is more centralized and there is no need to carry wood or wood materials during use. It is convenient and fast, which improves production efficiency and saves costs.

[0053] In addition, the system also includes a conveyor belt 3 6 and a dehumidification mechanism 7 arranged on the conveyor belt 3 6. The head end of the conveyor belt 3 6 corresponds to the discharge port of the hot mill 5, and is used to receive the wood fibers discharged from the hot mill 5. The dehumidification mechanism 7 is used to remove moisture from the wood fibers on the conveyor belt 3 6. The dehumidification mechanism 7 includes a plurality of fans 7-1, and sliders 7-2 are provided on both sides of the bottom of the base of the fan 7-1; a slide 6-2 matching the slider 7-2 is provided on the fixed platform 3 6-1 of the conveyor belt 3 6, and the fan 7-1 is slidably connected to the fixed platform. Since the humidity of the wood fibers after grinding is relatively high, the dehumidification mechanism 7 is set to perform preliminary dehumidification on them, and the air blown out by the fan 7-1 increases the air circulation on the wood fibers on the conveyor belt 3 6, increases convection, and thus removes the moisture on the wood fibers.

[0054] In this embodiment, the conveyor belt 1-1, the conveyor belt 2-3-5 and the conveyor belt 3-6 can all use existing conveyor belts, including driving wheels, driven wheels, support frames and conveyor belts, which are not described in detail here. For the convenience of control, the conveyor belt, cylinder, conveying motor 3-13, valve, cooking box 3-2, hot mill 5, fan 7-1 and other components can be electrically connected to the control system, which is an existing technical means and is not described in detail here.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
