Description

Technical Field

[0001] The present application relates to the technical field of wood cutting, and in particular to an anti-backward wood cutting device. Background Art

[0002] In the process of wooden furniture production, a flush saw is needed to cut the wood. A flush saw is a fast saw that can saw wood in multiple positions at the same time and batch-process wood of the same length. It is suitable for sawing, flush cutting and flush cutting of wood scraps of various square woods, wooden boards, slats, wooden floors, furniture woods, wooden pallets and other woods. The flush saw uses a chain to transport the wood. The staff only needs to put the wood to be cut on the conveying chain. The wood is transported to the bottom of the saw blade along the chain for cutting, and can be processed into wood of uniform length.

[0003] When the existing butt saw is in use, the wood is conveyed to the bottom of the saw blade through a chain, and then the wood is moved under the joint action of the clamping roller and the conveying roller. The saw blade cuts downward during the movement of the wood. Since the rotation direction of the saw blade is usually opposite to the transportation direction of the wood, when the high-speed rotating saw blade cuts the wood, it will generate a large driving force on the wood, which can easily cause the wood to slide in the opposite direction, resulting in reduced wood cutting efficiency. Therefore, during the sawing process, resistance needs to be applied to the wood to prevent the wood from moving backwards when the saw blade cuts the wood.

[0004] In the prior art, a bracket is arranged above the saw blade, and a metal plate is rotatably connected to the bracket. One end of the metal plate is rotatably connected to the bracket, and the other end rotates under the action of gravity to abut against the upper surface of the wood, so as to prevent the wood from moving backward by abutting against the wood by the metal plate. However, in actual use, it is found that due to the different sizes of the transported wood, it is difficult to ensure that the end of the metal plate can provide appropriate resistance to the wood by adopting the above structure. In particular, when the size of the wood is small, it is easy for the metal plate to be insufficient and unable to abut against the upper surface of the wood, and even more unable to form effective resistance to the wood, which is inconvenient to use. Utility Model Content

[0005] In order to achieve the purpose of compacting wood of different sizes without affecting the normal transportation of wood during the wood cutting process, thereby ensuring the wood cutting efficiency, the present application provides an anti-regression wood cutting device.

[0006] The present application provides an anti-regression wood cutting device, which adopts the following technical solution:

[0007] A wood cutting device for preventing back-up comprises a frame on which a saw blade, a conveying roller and a pressure roller are mounted, wherein a rotating shaft is arranged on the frame, a pressure plate is rotatably arranged on the rotating shaft, one end of the pressure plate is rotatably connected to the rotating shaft, and the other end of the pressure plate rotates under the action of gravity until it abuts against the upper surface of the wood, an adjusting component for adjusting the height of the rotating shaft is arranged on the frame, and a first limiting structure for limiting the rotation angle of the pressure plate is arranged on the frame.

[0008] By adopting the above technical scheme, the wood is transported by the conveying roller during use, and the wood is fixed by the pressing roller. When the wood is transported to the bottom of the saw blade, the end of the pressing plate rotates to abut against the upper surface of the wood under the action of gravity, and the pressing plate provides resistance to the wood, thereby preventing the wood from retreating when the saw blade cuts the wood. The angle of the pressing plate is limited by the first limiting structure to prevent the pressing plate from rotating too much, which causes the pressing plate to be unable to provide resistance to the wood when it retreats. At the same time, according to the different sizes of the wood, the staff adjusts the rotating shaft to a suitable position through the adjustment component, that is, the pressing plate is tilted above the wood, and the movable end of the pressing plate abuts against the upper surface of the wood, so as to provide resistance to the wood when cutting wood of different sizes while avoiding affecting the subsequent transportation of the wood. It is simple and convenient to use.

[0009] Preferably, the adjustment assembly includes a slider that slides on the frame and a screw that rotates on the frame, the slider is threadedly connected to the screw, the slider slides along the height direction of the frame, the rotating shaft is fixedly connected to the slider, and the end of the screw away from the frame is fixedly connected to a handwheel.

[0010] By adopting the above technical solution, when in use, the staff drives the screw to rotate by turning the hand wheel, and the rotation of the screw drives the slider to slide, so as to adjust the distance between the rotating wheel and the upper surface of the wood, which is convenient for the staff to use.

[0011] Preferably, the first limiting structure includes a fixed rod installed on the slider and an abutment plate rotatably mounted on the fixed rod, one end of the abutment plate is rotatably connected to the fixed rod, and the other end abuts against the side wall of the pressure plate, the fixed rod and the abutment plate are both located below the pressure plate, and a lifting assembly for lifting the abutment plate is provided on the abutment plate.

[0012] By adopting the above technical solution, the lifting component is used to limit the rotation of the abutment plate during use. On the one hand, it ensures that the end of the abutment plate abuts against the side wall of the clamping plate, thereby limiting the position of the clamping plate and preventing the clamping plate from rotating too much. On the other hand, the lifting component is used to lift the abutment plate, and the lifting of the abutment plate drives the clamping plate to rotate upward, thereby making the clamping plate separate from the wood, making it convenient for the staff to use.

[0013] Preferably, the lifting assembly includes a connecting sleeve fixedly connected to the end of the abutment plate, a mounting plate fixedly connected to the connecting sleeve, and a handle fixedly connected to the mounting plate. A second limiting structure for limiting the rotating mounting plate is provided between the mounting plate and the slider.

[0014] By adopting the above technical solution, when in use, the staff drives the mounting plate to rotate by shaking the handle, and the rotation of the mounting plate drives the abutment plate to rotate synchronously, thereby lifting the abutment plate. After the abutment plate is lifted to a specified height, the mounting plate is limited by the second limiting structure, thereby fixing the lifting height of the abutment plate.

[0015] Preferably, the second limiting structure includes a folding plate fixedly connected to the sliding block, an insertion rod sliding on the folding plate, a limiting block fixed to the insertion rod, and a spring arranged between the limiting block and the folding plate. The mounting plate is provided with a plug hole for embedding the plug rod, one end of the plug rod passes through the folding plate and is inserted into the plug hole, the spring is sleeved on the plug rod, one end of the spring is fixedly connected to the folding plate, and the other end is fixedly connected to the limiting block.

[0016] By adopting the above technical solution, when in use, the insertion rod is pulled to make the end of the insertion rod disengage from the insertion hole, so that it is convenient for the staff to lift the clamping plate by turning the handle. At this time, the spring is stretched. When the abutment plate is lifted to the specified height, it is only necessary to loosen the insertion rod. Under the elastic force of the spring, the insertion rod is reset so that the side wall of the insertion rod abuts against the side wall of the mounting plate, thereby limiting the mounting plate through the insertion rod to prevent the movable end of the clamping plate from rotating downward under the action of gravity, thereby achieving lifting of the clamping plate, which is simple and convenient to use.

[0017] Preferably, a connecting block is provided at one end of the fixing rod away from the sliding block, one end of the connecting block is fixedly connected to the fixing rod, and the other end is rotatably connected to the rotating shaft.

[0018] By adopting the above technical solution, a connecting block is set during use to fix the rotating shaft and the fixed rod without affecting the rotation of the clamping plate, thereby improving the stability of the end of the fixed rod and also increasing the stability of the abutment plate abutting against the clamping plate.

[0019] Preferably, the clamping plate includes a plurality of rod bodies, which are arranged side by side along the axial direction of the rotating shaft, one end of the rod body is rotatably connected to the rotating shaft, and the other end is used to abut against the wood, and the rotating shaft is provided with a clamping structure for preventing the rod body from detaching from the rotating shaft.

[0020] By adopting the above technical solution, multiple rods are set during use. When the surface of the wood is uneven, after the rods hit the concave and convex parts of the wood, only the several rods that are in contact will rotate upward, and the entire pressing plate will not rotate upward, thereby increasing the resistance of the pressing plate to the wood. Through the pressing structure, the connection between the multiple rods and the rotating shaft is realized, which is simple and convenient to use.

[0021] Preferably, the clamping structure includes a threaded rod fixedly connected to the end of the rotating shaft, a pressing plate sleeved on the rotating shaft, and an abutting nut abutting against the pressing plate, wherein the abutting nut is threadedly connected to the threaded rod.

[0022] By adopting the above technical solution, multiple rods are pressed onto the rotating shaft through the pressure plate during use, and the abutment nut is screwed so that the abutment nut abuts against the pressure plate, thereby fixing the pressure plate and preventing the rods from detaching from the rotating shaft.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When in use, the abutment plate is used to abut and limit the pressing plate, so that the pressing plate can only rotate in the direction of wood conveying, but cannot rotate in the opposite direction of wood conveying. Then, the lower end of the pressing plate is used to squeeze the wood to form resistance, so as to prevent the wood from moving back when being cut and affecting the cutting rate of the wood. At the same time, the staff can adjust the height of the rotating shaft through the adjustment component according to the different sizes of the conveyed wood, so that the end of the pressing plate can abut on the upper surface of wood of different sizes, thereby improving the application range of the overall device and making it simple and convenient to use;

[0025] 2. When in use, the rod, the limit block and the spring are used in coordination. On the one hand, under the elastic force of the spring, the end of the rod is inserted into the insertion hole, so as to fix the angle of the mounting plate, thereby fixing the inclination angle of the abutment plate. When the clamping plate needs to be lifted, the limit block is pulled, and the movement of the limit block drives the rod to move, so that the end of the rod is separated from the insertion hole, and then the movable end of the abutment plate can be lifted by turning the handle;

[0026] 3. When in use, by screwing the clamping bolt, the staff can install multiple rods on the rotating shaft to assemble the clamping plate. At the same time, since the multiple rods are not connected to each other, when there are bumps on the surface of the wood, several rods that hit the bumps rotate upward, and the other rods remain stable, avoiding the situation in the prior art where the entire clamping plate rotates upward after hitting the bumps, affecting the use of the clamping plate.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1 -Attached Figure 8 This application is described in further detail.

[0037] The embodiment of the present application discloses an anti-backward wood cutting device.

[0038] Reference Figure 1, an anti-backward wood cutting device, including a frame 1 placed horizontally on the ground, a saw blade 2, a conveying roller 3 and a pressing roller 4 are installed on the frame 1, the saw blade 2 and the pressing roller 4 are located above the wood 30, the conveying roller 3 is located below the wood 30, and an anti-backward structure 5 is arranged on the frame 1; when in use, the wood 30 is transported by the conveying roller 3, and the pressing roller 4 is used to press the wood 30 during transportation to ensure that the wood 30 remains stable when being cut by the saw blade 2, and the anti-backward structure 5 provides resistance for the wood 30, so as to avoid pushing the wood 30 backward when the saw blade 2 rotates at a high speed to cut the wood 30, thereby ensuring the cutting efficiency of the wood 30.

[0039] Reference Figure 1 and Figure 2 The anti-backward structure 5 includes a rotating shaft 51 and a pressing plate 52. The rotating shaft 51 is fixedly connected to the frame 1. One end of the pressing plate 52 is rotatably connected to the rotating shaft 51, and the other end is a movable end. The movable end of the rotating shaft 51 rotates under the action of gravity to abut against the upper surface of the wood 30. The pressing plate 52 is arranged above the wood 30 in an inclined manner as a whole, and the movable end of the pressing plate 52 faces the transportation direction of the wood 30. When the wood 30 is transported to pass through the pressing plate 52 during use, the movable end of the pressing plate 52 abuts against the upper surface of the wood 30. When the saw blade 2 cuts the wood 30, a large thrust will be generated when the saw blade 2 rotates at a high speed, and the direction of the thrust is opposite to the transportation direction of the wood 30. Therefore, when the saw blade 2 cuts the wood 30, the wood 30 will be pushed backward. At this time, under the abutment of the movable end of the pressing plate 52, a resistance to prevent backward movement is provided to the wood 30, thereby ensuring the efficiency of cutting when the wood 30 is transported.

[0040] Reference Figure 2 and Figure 3 The pressing plate 52 includes a plurality of rod bodies 521, and the plurality of rod bodies 521 are arranged side by side along the axial direction of the rotating shaft 51. One end of the rod body 521 is rotatably connected to the rotating shaft 51, and the other end is a movable end. A pressing structure 20 is provided on the rotating shaft 51, and the pressing structure 20 is used to prevent the rod body 521 from being separated from the rotating shaft 51. When in use, after the plurality of rod bodies 521 are installed on the rotating shaft 51, the plurality of rod bodies 521 can be pressed by the pressing structure 20, thereby realizing the assembly of the pressing plate 52. At the same time, since the plurality of rod bodies 521 are not connected to each other, when there is a concave-convex structure on the upper surface of the transported wood 30, only the rod body 521 in contact with the concave-convex structure rotates upward, so as to avoid affecting the transportation of the wood 30. At the same time, the other rod bodies 521 remain stable, thereby ensuring the abutment against the wood 30.

[0041] Reference Figure 2 and Figure 4The clamping structure 20 includes a threaded rod 201, a pressing plate 202 and abutment nut 203. The threaded rod 201 is fixedly connected to the end of the rotating shaft 51 away from the frame 1, the pressing plate 202 is sleeved on the rotating shaft 51, and the abutment nut 203 is threadedly connected to the threaded rod 201; when in use, after a plurality of rod bodies 521 are installed on the rotating shaft 51, the pressing plate 202 is sleeved on the rotating shaft 51, the rod body 521 is abutted by the pressing plate 202, and then the abutment nut 203 is screwed so that the abutment nut 203 is rotated to abut the pressing plate 202, thereby realizing the assembly of the clamping plate 52, which is simple and convenient to use.

[0042] Reference Figure 1 and Figure 5 , an adjusting assembly 6 is installed on the frame 1, and the adjusting assembly 6 is used to adjust the distance between the rotating shaft 51 and the upper surface of the wood 30. The adjusting assembly 6 includes a slider 61 and a screw 62. The slider 61 is slidably connected to the frame 1, and the bottom end of the screw 62 rotates on the frame 1. The top of the screw 62 passes through the slider 61 and the frame 1 and is located above the frame 1. The slider 61 and the screw 62 are threadedly connected, and a hand wheel 63 is fixedly connected to the top of the screw 62, and the rotating shaft 51 is fixedly connected to the slider 61; when in use, the staff drives the screw 62 to rotate by turning the hand wheel 63 according to the size of the transported wood 30. The rotation of the screw 62 drives the slider 61 to slide along the height direction of the frame 1, and the sliding of the slider 61 drives the lifting and lowering of the rotating shaft 51, thereby adjusting the height of the abutment plate 72, thereby ensuring that the movable end of the abutment plate 72 is always in contact with the upper surface of the wood 30, and the abutment plate 72 is tilted as a whole.

[0043] Reference Figure 2 and Figure 6 In order to prevent the pressing plate 52 from rotating too much, a first limiting structure 7 is installed on the slider 61. The first limiting structure 7 is used to limit the rotation angle of the pressing plate 52. The first limiting structure 7 includes a fixing rod 71 and an abutting plate 72. The fixing rod 71 is fixedly connected to the slider 61, and one end of the abutting plate 72 is rotatably connected to the fixing rod 71. The other end of the abutting plate 72 abuts against the side wall of the pressing plate 52, and the fixing rod 71 and the abutting plate 72 are both located below the pressing plate 52. A connecting block 10 is provided at one end of the block 61, one end of the connecting block 10 is fixedly connected to the fixing rod 71, and the other end of the connecting block 10 is rotatably connected to the end of the rotating shaft 51; when in use, the clamping plate 52 is limited by the first limiting structure 7, so as to prevent the clamping plate 52 from rotating counterclockwise to a vertical angle, thereby ensuring that the abutment plate 72 does not affect the transportation of the wood 30, and at the same time, the ends of the rotating shaft 51 and the fixing rod 71 are connected by the connecting block 10, thereby improving the stability of the rotating shaft 51 and the fixing rod 71.

[0044] Reference Figure 2 and Figure 7The lifting assembly 8 is used to lift the movable end of the pressing plate 52 so that the movable end of the pressing plate 52 can be rotated and separated from the upper surface of the wood 30. The lifting assembly 8 includes a connecting sleeve 81, a mounting plate 82 and a handle 83. The connecting sleeve 81 is cylindrical as a whole. The connecting sleeve 81 is fixedly connected to the end of the abutment plate 72 close to the slider 61. The connecting sleeve 81 is coaxially rotatably connected to the fixing rod 71, the mounting plate 82 is clamped and fixed on the connecting sleeve 81, and the handle 83 is fixedly connected to the mounting plate 82. When in use, the staff drives the mounting plate 82 to rotate by turning the handle 83, and the rotation of the mounting plate 82 drives the connecting sleeve 81 to rotate synchronously, thereby driving the abutment plate 72 to rotate to a specified angle, thereby lifting the pressing plate 52 so that the movable end of the pressing plate 52 rotates clockwise to separate from the upper surface of the wood 30.

[0045] Reference Figure 2 and Figure 8 In order to realize the positioning of the abutment plate 72 after the rotation, a second limiting structure 9 is provided between the slider 61 and the mounting plate 82. The second limiting structure 9 includes a folding plate 91, an insert rod 92, a limiting block 93 and a spring 94. The folding plate 91 is fixedly connected to the slider 61. The limiting block 93 is integrally formed at the end of the insert rod 92. A plug hole 95 is provided on the mounting plate 82. The end of the insert rod 92 away from the limiting block 93 passes through the folding plate 91 and is inserted into the plug hole 95. The spring 94 is provided between the folding plate 91 and the limiting block 93. The spring 94 is sleeved on the insert rod 92, and the spring 94 is provided between the folding plate 91 and the limiting block 93. One end is fixedly connected to the folding plate 91, and the other end is fixedly connected to the stopper 93; when in use, the staff pulls the stopper 93 to drive the end of the plug rod 92 to disengage from the insertion hole 95, and then the pressing plate 52 can be driven to rotate by turning the handle 83. When the mounting plate 82 rotates to a specified angle, it is only necessary to loosen the stopper 93. Under the elastic force of the spring 94, the plug rod 92 is reset, and the end side wall of the plug rod 92 abuts against the side wall of the mounting plate 82, thereby preventing the movable end of the pressing plate 52 from rotating downward under the action of gravity, thereby lifting the movable end of the pressing plate 52.

[0046] The implementation principle of the embodiment of the present application is as follows: when in use, the wood 30 is transported by the conveying roller 3, the wood 30 is pressed by the pressing roller 4 to prevent the wood 30 from shaking, and the wood 30 is cut by the saw blade 2. When the high-speed rotating saw blade 2 cuts the wood 30, the movable end of the pressing plate 52 arranged in an inclined manner abuts against the upper surface of the wood 30, thereby providing resistance for the wood 30 to prevent the wood 30 from moving backward when being cut, thereby ensuring the efficiency of cutting the wood 30; when the size of the transported wood 30 changes, the staff can drive the screw 62 to rotate by turning the hand wheel 63, thereby driving the slider 61 to rise and fall, and the slider 61 rises and falls to drive the rotating shaft 5 1 is lifted and lowered, thereby adjusting the height of the pressing plate 52, ensuring that when transporting wood 30 of different sizes, the movable end of the pressing plate 52 can abut against the upper surface of the wood 30, thereby providing an anti-backward resistance for the wood 30; when the staff needs to back the wood 30, they only need to rotate the handle 83 to drive the mounting plate 82 to rotate, and the rotation of the mounting plate 82 drives the movable end of the abutting plate 72 to rotate upward, thereby lifting the pressing plate 52, so that the end of the pressing plate 52 rotates to be separated from the upper surface of the wood 30, thereby realizing the backing of the wood 30 to the initial position, without removing the anti-backward structure 5, which is simple and convenient to use.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
