Description

Technical Field

However, the existing timber cutting structure is complex, and the timber processing requires frequent loading and unloading. The process of each step of the board production cannot be coordinated, resulting in low timber processing efficiency and high processing costs. Utility Model Content

[0055] like Figure 1-5 A wood cutting and sorting line, which includes, in sequence along the conveying direction of the wood planks: a width fixing device 1, a sanding device 2, a sorting device 3, and a cutting device 4;

[0056] The width-fixing device 1 is equipped with a plurality of width-fixing cutters 11 with equal spacing; the plurality of width-fixing cutters 11 are perpendicularly distributed in the conveying direction of the wooden board and are used to cut the whole wooden board into several strips;

[0057] The sanding mechanism 23 is used to sand the surface of the wood board;

[0058] The sorting device 3 is used to output qualified wooden boards to the sorting and discharge area 33, and to output unqualified wooden boards to the cutting device 4;

[0059] The slicing device 4 includes: a slicing frame 41 and a clamping unit 42;

[0060] Multiple pressing units 42 are sequentially distributed on the cutting frame 41 along the conveying direction of the wooden board; each pressing unit 42 includes: an upper pressure roller 421, a lower pressure roller 422, and a segmenting cutter 423;

[0061] The upper pressure roller 421 and the lower pressure roller 422 move toward each other to jointly press the wooden board; the lower pressure roller 422 is used to transport the wooden board; the segmenting cutter 423 is vertically and vertically arranged between the two pressing units 42 to cut a single wooden board into multiple segments.

[0062] This solution provides a wood cutting and sorting line, which is equipped with a width-fixing device 1, a sanding device 2, a sorting device 3 and a segmenting device 4 arranged in sequence. It can perform width fixing, sanding, sorting and segmenting of wood boards, realize the assembly line processing of wood boards, and solve the problems of low processing efficiency and high processing cost caused by the complex structure of existing wood cutting.

[0063] Specifically, the width-fixing device 1, the grinding device 2, the sorting device 3, and the cutting device 4 are arranged sequentially. Each of them can be equipped with one or more conveying devices for conveying wooden boards as needed to ensure that the wooden boards are conveyed in sequence. The width-fixing device 1 is equipped with multiple width-fixing cutters 11, and the width-fixing cutters 11 are distributed perpendicular to the conveying direction of the wooden boards. Therefore, when a whole wooden board passes by the width-fixing cutters 11, the width-fixing cutters 11 can cut the wooden board. Since the width-fixing cutters 11 are evenly distributed, the whole conveyed wooden board can be cut into several wooden boards of equal width and conveyed to the grinding device 2. After receiving multiple wooden boards, the grinding device 2 will grind the multiple wooden boards to remove impurities on the surface of the wooden boards and improve the appearance of the wooden boards. The sorting device 3 can be used for manual sorting or automated mechanical sorting. For manual sorting, workers are required to visually inspect the surface of each plank and determine if there are any defects. If so, the plank is marked with a marker 32 and transferred to the cutting device 4; otherwise, each plank is manually removed from the sorting line and stacked in the sorting discharge area 33. For automated mechanical sorting, an industrial camera is used to identify the surface of the planks. By acquiring real-time images of the plank surface and comparing them with standard images, it is determined whether there are any defects. If so, the plank is marked with a marker 32 and transferred to the cutting device 4; otherwise, each plank is manually removed from the sorting line and stacked in the sorting discharge area 33. The segmentation device 4 receives each wooden board and uses clamping units 42 at different positions to cut the board into different segments. Specifically, the upper pressure roller 421 and the lower pressure roller 422 move relative to each other to clamp the wooden board, and the segmenting cutter 423 can move up and down. When the segmenting cutter 423 moves, it cuts the wooden board into different segments. Since there are multiple clamping units 42, only two of the segmenting cutters 423 need to be adjusted to cut the wooden board into any length. Furthermore, since each clamping unit 42 is independently adjustable, a single wooden board can be cut by different clamping units 42, thereby shortening the cutting time and improving processing efficiency. In this way, wooden boards can be fixed in width, sanded, sorted, and segmented, realizing automatic processing of wooden boards and solving the problems of low processing efficiency and high processing cost caused by the complex structure of existing wood cutting.

[0064] Optimally, the clamping unit 42 includes: a wheel lifting driver 424, a rotary wheel driver 425, and a blade lifting driver 426;

[0065] The wheel lifting driver 424 is mounted on the cutting frame 41. The output end of the wheel lifting driver 424 is connected to the upper pressure wheel 421 and is used to drive the upper pressure wheel 421 to move up and down. The output end of the rotary wheel driver 425 is connected to the lower pressure wheel 422 and is used to drive the lower pressure wheel 422 to rotate and drive the wooden board to move. The output end of the knife lifting driver 426 is connected to the segmenting knife 423 and is used to drive the segmenting knife 423 to move up and down.

[0066] The wheel lifting driver 424 drives the upper pressure wheel 421 to move up and down, allowing it to move closer to or further away from the lower pressure wheel 422. When the upper pressure wheel 421 moves towards the lower pressure wheel 422, the two wheels work together to press the wooden board firmly. At this point, the knife lifting driver 426 can be activated, driving the segmenting cutter 423 to rise or fall, thus cutting the wooden board into different segments. Subsequently, the rotary wheel driver 425 can drive the lower pressure wheel 422 to rotate, thereby moving the wooden board on its upper surface. The wooden board passes through multiple pressing units 42 of the cutting frame 41. Alternatively, the upper pressure wheel 421 and the lower pressure wheel 422 can rotate. While both are pressing the wooden board, the rotary wheel driver 425 continuously drives the lower pressure wheel 422 to rotate, maintaining the movement of the wooden board. Then, the knife lifting driver 426 is activated, driving the segmenting cutter 423 to rise and cut the wooden board.

[0067] The wheel lifting driver 424 and the knife lifting driver 426 are known mechanisms with lifting functions, such as cylinders, hydraulic cylinders, motors and lead screws, etc., as long as the lifting function is achieved.

[0068] The rotary drive 425 is a known mechanism with a drive rotation function, such as a motor, or a combination of a motor and a reducer.

[0069] Alternatively, the cutting device 4 may include: a blade 43;

[0070] The blade 43 is horizontally mounted on the cutting frame 41 and located between the upper surfaces of two horizontally adjacent lower pressure rollers 422; the blade 43 is provided with a cutting outlet 431, and the segmenting cutter 423 is raised and lowered at the cutting outlet 431.

[0071] The blade plate 43 can be used to lift the wooden board upwards. When the wooden board is fed into the cutting frame 41, the bottom surface of the wooden board contacts the pressure roller 422. When the wooden board is cut, the length of each segment of the wooden board is shortened, so each segment of the wooden board may fall below the pressure roller 422. To address this, the blade plate 43 fills the space between the pressure rollers 422, which can prevent the shorter segments of the wooden board from leaving the conveying direction. The wooden board that remains on the blade plate 43 can be pushed out of the cutting frame 41 by the subsequent uncut wooden board along the conveying direction. The blade plate 43 of this solution has a cutting outlet 431, which is the cutting position of the segmenting cutter 423. On the one hand, it can provide a guiding function for the segmenting cutter 423 to ensure stable cutting, and on the other hand, it can not affect the normal conveying of the wooden board.

[0072] Alternatively, the cutting device 4 may include: an anti-detachment plate 44;

[0073] The upper end of the anti-detachment plate 44 is repositionably and swingably mounted on the cutting frame 41, and the anti-detachment plate 44 is tilted downwards; the anti-detachment plate 44 is located at the end of the arrangement of the plurality of pressing units 42, and part of the wooden board is tilted up to abut against the anti-detachment plate 44 at the last pressing wheel 422.

[0074] The anti-detachment plate 44 is located at the end of the pressing unit 42. When the wooden board passes the last two lower pressure rollers 422 at the end away from the conveying direction, the segmenting cutters 423 of the two lower pressure rollers 422 cut the wooden board. Since the wheel surface of the lower pressure rollers 422 has an arc structure and the wooden board is no longer pressed by the two upper pressure rollers 421 simultaneously, the wooden board swings around the lower pressure rollers 422, causing the end closer to the conveying direction to swing to abut against the anti-detachment plate 44. The anti-detachment plate 44 swings against the cutting frame 41, and then the anti-detachment plate 44 resets under the action of gravity, pressing the wooden board down again. This ensures that the wooden board remains within the conveying direction after it tilts up, improving stability. The upper end of the anti-detachment plate 44 can be reset and swung on the cutting frame 41, specifically through a spring connection, gas spring connection, etc., as long as it supports the anti-detachment plate 44 to tilt downwards.

[0075] Optimally, the width-fixing device 1 includes: a width-fixing frame 12, a width-fixing conveying mechanism 13, a width-fixing driver 14, and the width-fixing cutter 11;

[0076] The width-fixing frame 12 is mounted on the width-fixing conveying mechanism 13; the conveying end of the width-fixing conveying mechanism 13 is used to output the wooden board to the sanding device 2; the width-fixing cutter 11 is a saw blade, and the width-fixing cutter 11 is close to the conveying end of the width-fixing conveying mechanism 13; the width-fixing driver 14 is mounted on the width-fixing frame 12; the output end of the width-fixing driver 14 is connected to the width-fixing cutter 11 and is used to drive the width-fixing cutter 11 to rotate.

[0077] The width-fixed conveying mechanism 13 is a known device with a conveying function, which only needs to convey the wooden boards. The width-fixed conveying mechanism 13 conveys the wooden boards to the sanding device 2. The output end of the width-fixed driver 14 is directly or indirectly connected to the width-fixed cutter 11. Multiple width-fixed cutters 11 can be synchronously connected to a single shaft, and then the width-fixed driver 14 drives the shaft to rotate, thereby simultaneously driving multiple width-fixed cutters 11 to rotate; alternatively, a single width-fixed cutter 11 can be connected to a single width-fixed driver 14. The width-fixed cutter 11 is close to the conveying end of the width-fixed conveying mechanism 13 and cuts the wooden boards at the conveying end of the width-fixed conveying mechanism 13, thereby fixing the width of each wooden board according to the gap of the width-fixed cutter 11.

[0078] The fixed-width driver 14 is a known mechanism with a drive rotation function, such as a motor, or a combination of a motor and a reducer, as long as it can drive the fixed-width cutter 11 to rotate.

[0079] Optimally, the fixed-width conveying mechanism 13 includes: a fixed-width conveying frame 131, a fixed-width conveying shaft 132, a fixed-width conveying wheel 133, a fixed-width conveying belt 134, and a fixed-width conveying motor 135;

[0080] Multiple fixed-width conveyor shafts 132 are rotatably mounted on the fixed-width conveyor frame 131; multiple fixed-width conveyor wheels 133 are mounted on the same fixed-width conveyor shaft 132; each fixed-width conveyor belt 134 connects multiple fixed-width conveyor wheels 133 aligned in a straight line with the fixed-width conveyor shafts 132, and there are multiple fixed-width conveyor belts 134, with adjacent fixed-width conveyor belts 134 spaced apart; the output end of the fixed-width conveyor motor 135 is connected to one of the fixed-width conveyor shafts 132, and is used to drive the fixed-width conveyor shaft 132 to rotate, thereby driving multiple fixed-width conveyor shafts 132 and their fixed-width conveyor wheels 133 to rotate, causing the wooden boards on the fixed-width conveyor belts 134 to move.

[0081] This solution preferably uses a conveyor belt structure to transport wooden boards. Multiple fixed-width conveyor shafts 132 are mounted on a fixed-width conveyor frame 131. Each fixed-width conveyor shaft 132 is equipped with a fixed-width conveyor wheel 133, and at least one fixed-width conveyor wheel 133 of the multiple fixed-width conveyor shafts 132 is aligned in a straight line. A fixed-width conveyor belt 134 connects the aligned fixed-width conveyor wheels 133 of the multiple fixed-width conveyor shafts 132. When a fixed-width conveyor motor 135 drives one of the fixed-width conveyor shafts 132 to rotate, the fixed-width conveyor shaft 132 drives the fixed-width conveyor belt 134 to rotate through its fixed-width conveyor wheel 133, thereby driving the multiple fixed-width shafts 132 and their fixed-width conveyor wheels 133 to rotate. In this way, the upper surface of the fixed-width conveyor belt 134 can transport wooden boards, and after the wooden boards are cut, they can be transported separately by different fixed-width conveyor belts 134.

[0082] Optimally, the fixed-width cutter 11 is vertically distributed in the gap formed between the fixed-width conveyor belt 134 and the fixed-width conveyor belt 134;

[0083] The fixed-width conveying mechanism 13 further includes: a cutting and limiting pressure member 136;

[0084] The cutting limiting pressure member 136 is installed on the front and rear sides of the fixed width conveyor frame 131, with the bottom surface of the cutting limiting pressure member 136 facing the fixed width conveyor belt 134 and the bottom surface of the cutting limiting pressure member 136 contacting the wooden board.

[0085] The width-fixed cutter 11 is located in the gap between the width-fixed conveyor belts 134 and 135. When the wooden board passes through the width-fixed cutter 11, it is pressed by the cutting limiting pressure member 136. The width-fixed cutter 11 directly cuts the wooden board between the width-fixed conveyor belts 134. Under the pressure or limiting action of the cutting limiting pressure member 136, the wooden board can be kept horizontally conveyed, thereby ensuring the angular stability of the wooden board before and after cutting. The cutting limiting pressure member 136 can be a plate-like structure that directly contacts the surface of the wooden board to prevent the wooden board from warping; the cutting limiting pressure member 136 can also be a wheel or roller structure that can rotate relative to the surface of the wooden board and can cooperate with the width-fixed conveyor belt 134 for conveying, thereby stabilizing the position of the wooden board during cutting.

[0086] Alternatively, the polishing device 2 may include: a polishing base 21, a polishing conveying mechanism 22, and a polishing mechanism 23;

[0087] The grinding conveying mechanism 22 is installed on the grinding machine base 21; the grinding mechanism 23 is installed on the grinding machine base 21 and is located above the grinding conveying mechanism 22.

[0088] The grinding conveying mechanism 22 includes: a grinding conveying base 221, a grinding conveying drive wheel 222, a grinding conveying driven wheel 223, a grinding conveying belt 224, and a grinding conveying motor 225;

[0089] The sanding conveyor seat 221 is mounted on the sanding machine base 21; the sanding conveyor drive wheel 222 and the sanding conveyor driven wheel 223 are respectively mounted on the sanding conveyor seat 221, and the sanding conveyor belt 224 connects the sanding conveyor drive wheel 222 and the sanding conveyor driven wheel 223 to rotate synchronously; the output end of the sanding conveyor motor 225 is connected to the sanding conveyor drive wheel 222 to drive the sanding conveyor drive wheel 222 to rotate, and drives the sanding conveyor belt 224 to rotate through the sanding conveyor driven wheel 223, so that the sanding conveyor belt 224 drives the wood board to be conveyed;

[0090] The sanding mechanism 23 is equipped with sandpaper 235, which moves relative to the wooden board of the sanding conveyor belt 224.

[0091] The grinding conveyor motor 225 drives the grinding conveyor drive wheel 222 to rotate, which in turn drives the grinding conveyor driven wheel 223 to rotate under the action of the grinding conveyor belt 224, thereby driving the straight section of the grinding conveyor belt 224 to move and convey the wooden board to the sorting device 3. The wooden board moves past the bottom of the grinding mechanism 23, and the sandpaper 235 of the grinding mechanism 23 grinds the wooden board to remove impurities from the surface of the wooden board.

[0092] The sandpaper 235 only needs to move relative to the wooden board, for example, by fixing the position of the sandpaper 235 or by wrapping the sandpaper 235 around a roller structure. In the preferred embodiment, the sanding mechanism 23 uses a conveyor belt structure.

[0093] Optimally, the polishing mechanism 23 includes: a polishing base 231, a polishing drive wheel 232, a polishing driven wheel 233, a polishing motor 234, and sandpaper 235;

[0094] The sanding base 231 is mounted on the sanding machine base 21; the sanding drive wheel 232 and the sanding driven wheel 233 are respectively mounted on the sanding base 231; the sandpaper 235 is connected end to end to form a ring structure, which connects the sanding drive wheel 232 and the sanding driven wheel 233 to rotate synchronously; the output end of the sanding motor 234 is connected to the sanding drive wheel 232 to drive the sanding drive wheel 232 to rotate, and the sandpaper 235 is driven to rotate through the sanding driven wheel 233, so that the sandpaper 235 moves relative to the surface of the wood board.

[0095] The sanding motor 234 drives the sanding drive wheel 232 to rotate, which in turn drives the sanding driven wheel 233 to rotate under the action of the sandpaper 235. This causes the sandpaper 235 to move in a straight line, and the sandpaper 235 moves relative to the surface of the wood board. The sandpaper 235 sands the surface of the wood board, increasing the sanding area and improving sanding efficiency.

[0096] Alternatively, the sorting device 3 may include: a sorting conveyor 31, a marker 32, and the sorting discharge area 33;

[0097] The input end of the sorting and conveying device 31 is used to receive the wooden boards from the sanding device 2; the output end of the sorting and conveying device 31 is connected to the cutting device 4 and is used to output the unqualified wooden boards to the cutting device 4.
