Description

Technical Field

[0001] The present invention relates to the technical field of wood board cutting equipment, and in particular to a cutting machine for carbonized wood floors. Background Art

[0002] Carbonized wood floors are made by carbonizing wood boards. The sizes of wood floors are different, and the specifications for daily installation of wood floors need to be selected. In order to produce wood floors of different specifications, a whole wood board needs to be cut into multiple wood floors of the same specification, and then carbonized to obtain the required carbonized wood floors. For example, an automatic wood board cutting machine disclosed in the publication number CN118081907B can be used for cutting work.

[0003] During actual production, in order to prevent the accumulation of wood chips from affecting the normal cutting work of the equipment, it is necessary to clean them. And in order to ensure the production efficiency of the device, the circular saw in the equipment is still in working state when cleaning the wood chips. Generally, it is necessary to manually clean the wood chips and carry the wood boards up and down. The rapidly rotating circular saw will cause harm to the staff, resulting in production accidents, and the safety of the equipment during use is relatively low. Summary of the Invention

[0004] In view of the above-mentioned drawbacks of the prior art, the present invention provides a cutting machine for carbonized wood floors, which can effectively solve the problem that the circular saw will cause harm to workers when cleaning wood chips or carrying wood boards in the prior art.

[0005] To achieve the above object, the present invention is realized through the following technical solutions:

[0006] The present invention provides a cutting machine for carbonized wood floors, including a workbench main body;

[0007] A clamping mechanism provided on the workbench main body;

[0008] A cutting mechanism fixed inside the workbench main body. The cutting mechanism includes a fixed frame fixed to the top wall of the workbench main body. A cutting circular saw is rotatably connected inside the fixed frame. One end of the cutting circular saw close to the cylinder is fixed with a rectangular shell. A reciprocating lead screw is rotatably connected inside the rectangular shell. A reciprocating block is sleeved on the surface of the reciprocating lead screw. One end of the reciprocating lead screw far from the cutting circular saw is fixed with a friction wheel by a connecting rod. The friction wheel is indirectly driven by a component in the clamping mechanism. A motor fixed to the top wall of the workbench main body is provided between the rectangular shell and the friction wheel. A sleeve is fixed to the lower end of the reciprocating block. A cross hole is axially opened in the sleeve. A driving frame is fixed to the output end of the motor and one end of the cutting circular saw close to the motor.

[0009] Preferably, when the sleeve is simultaneously sleeved on the surfaces of the two driving frames, the motor drives the cutting circular saw to rotate.

[0010] Preferably, the driving frame includes two cross bars respectively fixed to the output end of the motor and one end of the cutting circular saw. At least two elastic telescopic rods are evenly embedded in the two cross bars, and a cross block is fixed to the telescopic end of the elastic telescopic rod.

[0011] Preferably, a separation mechanism is provided in the workbench main body. Two axial flow fans are embedded in one inner wall of the workbench main body, and a cylinder is fixed to the other inner wall of the workbench main body.

[0012] The separation mechanism includes two V-shaped plates symmetrically fixed to the inner wall of the workbench main body. The V-shaped plates divide the workbench main body into a broken wood board collection cavity and two sawdust collection cavities symmetric about the broken wood board collection cavity. Storage boxes are arranged in both the broken wood board collection cavity and the sawdust collection cavity. Rectangular grooves are symmetrically formed in the two V-shaped plates. Rotating door panels are symmetrically rotatably connected in the rectangular grooves. A support shell fixed to the inner wall of the workbench main body is arranged between the two V-shaped plates. A limiting plate is slidably connected to the bottom wall of the support shell. A plurality of limiting rods are symmetrically fixed to the upper end of the limiting plate. Two triangular plates are fixed to the upper end of the support shell. A hydraulic pipe is fixed to the inner wall of the V-shaped plate, and a pressure plate is fixed to the telescopic end of the hydraulic pipe.

[0013] Wherein, the output end of the cylinder is fixedly connected to the limiting plate. The limiting plate is of an isosceles trapezoid structure with two symmetrically distributed inclined surfaces.

[0014] Preferably, this cutting machine has a trimming working state and a cutting-off working state. When the device is in the trimming working state, the limiting rod is in contact with the rotating door panel closer to the cylinder, and the axial flow fan is in the starting state to separate the broken wood board and the sawdust. When the device is in the cutting-off working state, the limiting plate is in contact with the rotating door panel closer to the axial flow fan, and the axial flow fan is in the closed state and the sawdust falls freely.

[0015] Preferably, the clamping mechanism includes a clamping base indirectly driven by hydraulic oil. The clamping base is composed of a vertical clamping plate, a U-shaped connecting piece and a lateral clamping plate which are fixedly connected to each other in sequence. A threaded rod is rotatably connected in the vertical clamping plate. A fixed shell is threadedly connected to the surface of the threaded rod. A movable roller is arranged in the inner cavity of the fixed shell. A rectangular groove is formed in the vertical clamping plate close to the threaded rod. A pushing plate is arranged in the rectangular groove. A friction plate penetrating into the workbench main body is fixed to the lower end of the vertical clamping plate. At least one hydraulic rod is fixed to the side of the lateral clamping plate close to the axial flow fan, and a clamping plate is fixed to the telescopic end of the hydraulic rod.

[0016] Preferably, the lower end of the friction plate is in contact with the outer surface of the friction wheel.

[0017] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0018] First, only when the wooden board is about to contact the cutting circular saw, the sleeve will be sleeved on the surfaces of both driving frames at the same time, and the cutting circular saw will rotate to cut the wooden board. That is to say, when the worker is cleaning the sawdust and removing the cut wooden board, the cutting circular saw will be in a stationary state, ensuring the safety of the worker when using the equipment, reducing the danger level during the production process, and indirectly improving the production efficiency of the equipment.

[0019] Second, through the axial flow fan provided, the broken wooden boards and sawdust falling freely can be separated, and they are collected through different collection chambers and storage boxes. And the pressure plate among them can be hydraulically driven to compact the sawdust, turning the loose sawdust into sawdust blocks, facilitating the transportation work during subsequent processing, being able to make better use of the waste generated after cutting to make composite boards, and making the whole process more efficient.

[0020] Third, the equipment does not need to frequently start and stop the motor. Only by the frequent sleeving process of the two driving frames and the sleeve can the rotation of the cutting circular saw be controlled. Although there is wear between the sleeve and the driving frame, subsequent lubrication and maintenance are relatively convenient, and the overall replacement and use costs are reduced.

Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] Embodiment: Referring to Figures 1 to 9 , a cutting machine for carbonized wood floors, comprising a main body 1 of the workbench, a clamping mechanism 4 provided on the main body 1 of the workbench, a cutting mechanism 3 fixed in the main body 1 of the workbench, a separation mechanism 2 provided in the main body 1 of the workbench, two axial flow fans 11 fixed on the inner wall of the main body 1 of the workbench, and a cylinder 12 fixed on the inner wall on the other side of the main body 1 of the workbench;

[0035] It should be noted that after the wooden board is fixed by the clamping mechanism 4, through the cooperation between the clamping mechanism 4 and the components of the cutting mechanism 3, during the process of the clamping mechanism 4 driving the wooden board to move, the components in the cutting mechanism 3 can cut the wooden board. And when the wooden board does not contact the cutting components, the cutting components will remain stationary, ensuring the safety of workers when operating the equipment. During the edge-cutting process of the wooden board, broken wooden boards and wood chips will be generated, while when the wooden board is used for truncation, only wood chips will be generated. The processing techniques and requirements for broken wooden boards and wood chips are different in the production of composite boards. The axial flow fan 11 and the separation mechanism 2 can separate and collect the broken wooden boards and wood chips.

[0036] Furthermore, to better collect the broken wooden boards and wood chips generated during cutting, as Figure 4 and Figure 5 shown, the separation mechanism 2 includes two V-shaped plates 21 fixed to the inner wall of the workbench main body 1. The V-shaped plates 21 divide the workbench main body 1 into a broken wooden board collection chamber and two wood chip collection chambers symmetric about the broken wooden board collection chamber. Storage boxes 29 are provided in both the broken wooden board collection chamber and the wood chip collection chambers. The two V-shaped plates 21 are symmetrically provided with rectangular slots, and a rotating door panel 22 is rotatably connected in the rectangular slots. A support shell 23 fixed to the inner wall of the workbench main body 1 is provided between the two V-shaped plates 21. A limiting plate 24 is slidably connected to the bottom wall of the support shell 23. The output end of the cylinder 12 is fixedly connected to the limiting plate 24. The limiting plate 24 is an isosceles trapezoidal structure with two symmetrically distributed inclined surfaces.

[0037] Then, a plurality of limiting rods 25 are symmetrically fixed to the upper end of the limiting plate 24, and two triangular plates 26 are fixed to the upper end of the support shell 23. The falling wood chips will slide down through the inclined surfaces of the triangular plates 26 and the inclined surfaces provided on the surface of the limiting plate 24 into the storage boxes 29 in the two wood chip collection chambers. A hydraulic pipe 27 is fixed to the inner wall of the V-shaped plate 21, and a pressure plate 28 is fixed to the telescopic end of the hydraulic pipe 27. When hydraulic oil enters the hydraulic pipe 27, it will push the pressure plate 28 to move downward, compacting the wood chips in the two wood chip collection chambers, facilitating cleaning and subsequent transportation work.

[0038] This cutting machine has an edge-cutting working state and a truncation working state. When the equipment is in the edge-cutting working state, the limiting rod 25 is in contact with the rotating door panel 22 on the side close to the cylinder 12, and the axial flow fan 11 is in the starting state to separate the broken wooden boards and wood chips. When the equipment is in the truncation working state, the limiting plate 24 is in contact with the rotating door panel 22 on the side close to the axial flow fan 11, and the axial flow fan 11 is in the closed state and the wood chips fall freely.

[0039] It should be noted that when separating the broken wood boards and wood chips, two axial fans 11 need to be started. When the broken wood boards and wood chips are in free fall within the main body 1 of the workbench, the axial fans 11 will blow to separate the wood chips from the broken wood boards. The wood chips will enter the storage box body 29 on the other side, while the broken wood boards heavier than the wood chips will directly fall into the storage box body 29 in the broken wood board collection cavity. When only wood chips are generated during cutting, the limiting plate 24 will contact the limiting plate 24 on the side close to the axial fan 11 to make it rotate. When both wood chips and broken wood boards are generated during cutting, the limiting plate 24 will contact the rotating door plate 22 on the side close to the cylinder 12 to make it rotate. When it is necessary to clean the wood chips, the limiting plate 24 needs to be located between the two rotating door plates 22 to prevent the rotating door plate 22 from affecting the compaction of the wood chips by the pressure plate 28.

[0040] Furthermore, to ensure the safety during the use of the equipment, as Figure 6 shown, the cutting mechanism 3 includes a fixing frame 31 fixed to the top wall of the main body 1 of the workbench. A cutting circular saw 32 is rotatably connected within the fixing frame 31. One end of the cutting circular saw 32 close to the cylinder 12 is fixed with a rectangular shell 33. A reciprocating lead screw 34 is rotatably connected within the rectangular shell 33. A reciprocating block 35 is sleeved on the surface of the reciprocating lead screw 34. One end of the reciprocating lead screw 34 away from the cutting circular saw 32 is fixed with a friction wheel 36 by means of a connecting rod. The friction wheel 36 is indirectly driven by a component in the clamping mechanism 4;

[0041] Then, a motor 37 fixed to the top wall of the main body 1 of the workbench is provided between the rectangular shell 33 and the friction wheel 36. The lower end of the reciprocating block 35 is fixed with a sleeve 38. A cross hole is axially opened in the sleeve 38. The output end of the motor 37 and one end of the cutting circular saw 32 close to the motor 37 are both fixed with a driving frame 39. When the sleeve 38 is simultaneously sleeved on the surfaces of the two driving frames 39, the motor 37 drives the cutting circular saw 32 to rotate. Only when the wood board is about to contact the cutting circular saw 32, the sleeve 38 will be simultaneously sleeved on the surfaces of the two driving frames 39, and there is no need to frequently start and stop the motor 37;

[0042] It should be noted that if the current and voltage fluctuations of the motor 37 are too frequent, it will affect the electrical components inside the motor 37 and also cause a great impact on the mechanical part, thereby reducing the mechanical life of the motor 37. During the use process, try to avoid frequently starting and stopping the motor 37. Instead, control the rotation of the cutting circular saw 32 through the frequent sleeving process of the two driving frames 39 and the sleeve 38. Although it will also cause wear between the sleeve 38 and the driving frame 39, subsequent lubrication and maintenance are more convenient, and the overall replacement and use costs are reduced.

[0043] Furthermore, to enable the sleeve 38 to be sleeved on the surfaces of the two driving frames 39, as Figure 7As shown in the figure, the driving frame 39 includes two cross bars 391 respectively fixed to the output end of the motor 37 and one end of the cutting circular saw 32. At least two elastic telescopic rods 392 are evenly embedded in the two cross bars 391. A cross block 393 is fixed to the telescopic end of the elastic telescopic rod 392. Two contacts are provided on the inner wall of the sleeve 38. The motor 37 always rotates slowly in the non-cutting state until when the sleeve 38 simultaneously sleevs on the surfaces of the two cross bars 391, the two contacts will be triggered to cause the controller (it should be noted that the opening and closing of the electrical components in the present invention are all controlled by the controller, which is a mature existing control technology and not shown in the figure) to control the motor 37 to change from the slow rotation state to the fast rotation state, so that the sleeve 38 can be better sleeved on the surface of the cross bar 391, and at the same time, it does not affect the function of the cutting circular saw 32 to cut the wooden board.

[0044] To further illustrate, for the clamping work of the wooden board, as Figure 8 and Figure 9 shown, the clamping mechanism 4 includes a clamping base 41 indirectly driven by hydraulic oil. The clamping base 41 is composed of a vertical clamping plate, a U-shaped connecting piece and a lateral clamping plate which are sequentially and fixedly connected to each other. A threaded rod 42 is rotatably connected inside the vertical clamping plate. A fixed housing 43 is threadedly connected to the surface of the threaded rod 42. A movable roller 44 is provided in the inner cavity of the fixed housing 43. By the movable roller 44 fitting against the wooden board to fix it, it can be ensured that the wooden board will not shift during cutting, and it is also convenient to adjust the position of the wooden board so that it can be cut into wooden floors;

[0045] Then, a rectangular groove is opened on one side of the vertical clamping plate close to the threaded rod 42. A pushing plate 45 is provided in the rectangular groove. A friction plate 46 penetrating through the workbench main body 1 is fixed to the lower end of the vertical clamping plate. The lower end of the friction plate 46 is in contact with the outer surface of the friction wheel 36. At least one hydraulic rod 47 is fixed to one side of the lateral clamping plate close to the axial flow fan 11. A clamping plate 48 is fixed to the telescopic end of the hydraulic rod 47;

[0046] Then, a tool is needed to turn the threaded rod 42. Under the action of the threaded connection, when the threaded rod 42 rotates, it will drive the fixed housing 43 and the movable roller 44 to move downward at the same time. When the movable roller 44 touches the surface of the wooden board and presses it, the turning of the threaded rod 42 can be stopped. Then, the two hydraulic rods 47 are started to shorten, driving the clamping plate 48 therein to contact the surface of the wooden board, and the clamping work of the wooden board before cutting is completed.

[0047] The working principle of the present invention is as follows: Place the wooden board to be cut on the clamping base 41. If it is to be cut off, start the cylinder 12 to push the limit plate 24 to move towards the axial flow fan 11. When the limit plate 24 touches the rotating door plate 22, it will push the rotating door plate 22 to rotate, and at the same time, it will block one side port of the broken wood collection cavity. At this time, a tool needs to be used to turn the threaded rod 42. Under the action of threaded connection, when the threaded rod 42 rotates, it will drive the fixed housing 43 and the movable roller 44 to move downward at the same time. When the movable roller 44 touches the surface of the wooden board and presses it, stop turning the threaded rod 42. Then start the two hydraulic rods 47 to shorten, driving the clamping plate 48 among them to contact the surface of the wooden board, and the clamping work of the wooden board before cutting is completed. When cutting, the flatness of the cutting surface of the wooden board can be ensured, and at the same time, the specifications of the cut-off wooden boards can be ensured to be consistent;

[0048] Inject hydraulic oil into the device through the pumping device. The hydraulic oil will push the clamping base 41 to move towards the cutting circular saw 32. Start the motor 37 to drive the sleeve 38 to rotate. During the process of the clamping base 41 moving towards the cutting circular saw 32, the frictional force generated between the friction plate 46 and the friction wheel 36 will make the friction plate 46 drive the friction wheel 36 to rotate. The friction wheel 36 will drive the reciprocating screw rod 34 among them to rotate, so that the rotating reciprocating screw rod 34 drives the reciprocating block 35 sleeved on its surface to move. The sleeve 38 will move along with the reciprocating block 35. During the movement of the sleeve 38, it will be sleeved on the surfaces of the two driving frames 39 at the same time, so that the motor 37 can drive the cutting circular saw 32 to rotate through the two driving frames 39. And it is in this process that the wooden board fixed on the clamping base 41 will contact the cutting circular saw 32, and the wooden board will be cut off by the rapidly rotating cutting circular saw 32. The sandpaper attached to the surface of the cutting circular saw 32 can polish the cut surface of the wooden board;

[0049] At this time, the clamping base 41 will continue to move, so that the sleeve 38 will also continue to move until it is completely sleeved on the surface of the other driving frame 39, and the motor 37 will not be able to drive the cutting circular saw 32 to rotate. During this process, the cut-off wooden board can be manually removed, and at the same time, the sawdust can be pushed into the opening at the upper end of the workbench main body 1. At this time, the cutting circular saw 32 is in a static state and will not cause harm to the worker, ensuring the safety of the worker when operating the equipment. Then start the push plate 45 to push the wooden board to move, so that the subsequent cut-off wooden boards can be kept consistent. By pumping out the hydraulic oil through the pumping device, the clamping base 41 can be moved in the reverse direction to reset, and at the same time, the reciprocating block 35 will also drive the sleeve 38 to move in the reverse direction. During the reset process of the clamping base 41, the second wooden floor can be cut off. Then repeat the above actions in sequence, and a wooden board can be cut into multiple wooden floors with the same specifications;

[0050] The wood chips generated by cutting the wooden board will fall onto the inclined plane formed on the surface of the limit plate 24, and then slide into the storage box 29 in the wood chip collection cavity. When the device is used for trimming the wooden board, the cylinder 12 needs to be activated to pull the limit plate 24 to move away from the axial flow fan 11, so as to push the rotating door panel 22 on the other side to rotate. The process of cutting the wooden board is the same as the above, but the difference is that during the trimming process, two axial flow fans 11 need to be activated. When the broken wooden boards and wood chips fall freely in the workbench main body 1, the axial flow fans 11 will blow to separate the wood chips from the broken wooden boards. The wood chips will enter the storage box 29 on the other side, and the broken wooden boards heavier than the wood chips will directly fall into the storage box 29 in the broken wooden board collection cavity. When it is necessary to clean the wood chips, the cylinder 12 needs to be activated to push the limit plate 24 to move between the two rotating door panels 22. Then, the hydraulic oil is pumped again through the pumping device, and the hydraulic oil will enter the two hydraulic pipes 27, so that the hydraulic pipes 27 push the pressure plate 28 to move downward to compact the wood chips for subsequent transportation work.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
