[0002] Filing cabinets belong to the office furniture series, that is, cabinets used to store archival materials; they are relatively traditional equipment for storing archives, usually referring to boxes with lids and cabinets with doors, generally made of wood or metal. When making filing cabinets, the boards used need to be processed and cut, so a board cutting device is needed. The State Intellectual Property Office issued an authorization announcement on September 5, 2023, with the authorization announcement number CN115625372U: "A board cutting device for the production of electric control cabinets". The patent discloses a device for cutting boards by reciprocating movement of a cutting saw blade, but because the direction of the saw teeth on the cutting saw blade is fixed, the cutting saw blade can only cut when it moves in a specific direction, making it impossible for the cutting saw blade to cut back and forth, reducing practicality, and it takes time for the cutting saw blade to move back, which increases the processing time. Therefore, we designed a board cutting device for the production of filing cabinets. Summary of the Invention

[0018] A plate cutting device for processing filing cabinets, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6As shown, it includes a processing table 1, a cutting groove 2 is provided on the processing table 1, a cutting saw blade 3 is provided in the cutting groove 2, the cutting saw blade 3 is fixedly mounted on the rotating shaft 5, and the cutting saw blade 3 is coaxially arranged with the rotating shaft 5. The characteristics are: the processing table 1 is a hollow box body, a mounting plate 4 is provided in the processing table 1, the rotating shaft 5 is rotatably mounted on the mounting plate 4, a transmission mechanism is provided on the mounting plate 4, a driving mechanism is provided in the processing table 1, the driving mechanism can drive the mounting plate 4 to move back and forth, the transmission mechanism is connected to the driving mechanism, and the transmission mechanism is used to transmit the The drive mechanism is capable of driving the saw blade 3 to rotate. A T-shaped block 6 is fixedly mounted on one side of the mounting plate 4. A T-shaped slot 7 is formed on the inner wall of the processing table 1, corresponding to the T-shaped block 6. The two sides of the T-shaped slot 7 are semi-arc-shaped, and the height of the semi-arc-shaped portions is lower than the height of the middle portion of the T-shaped slot 7. The semi-arc-shaped portions of the T-shaped slot 7 are connected to the corresponding middle portion of the T-shaped slot 7 via an inclined portion. A steering mechanism is provided within the processing table 1. When the T-shaped block 6 slides into the semi-arc-shaped portion of the T-shaped slot 7, the mounting plate 4 is rotated 180 degrees under the action of the steering mechanism. The present invention has a simple structure and an ingenious design. By causing the saw blade 3 to move to both sides of the processing table 1, the saw blade 3 is moved into the processing table 1 to reverse direction, thereby achieving back-and-forth cutting of the saw blade 3, thereby increasing the practicality of the device. At the same time, the saw blade 3 is highly secure when it is moved into the processing table 1. In addition, the saw blade 3 can rotate and turn in a single drive mechanism, meeting practical needs and being suitable for promotion. When using the present invention, the plate to be cut is placed on the top side of the processing table 1, and then the mounting plate 4 is driven to move by the driving mechanism, and the cutting saw blade 3 is driven to rotate through the transmission of the transmission mechanism to cut the plate. When the driving mechanism drives the mounting plate 4 and the T-shaped block 6 to move to the inclined part of the T-shaped slot 7, the mounting plate 4 and the cutting saw blade 3 are guided downward by the inclined surface of the T-shaped slot 7 until the T-shaped block 6 moves into one end of the semi-arc part of the T-shaped slot 7. At the same time, the cutting saw blade 3 is completely moved into the workbench 1. At this time, the mounting plate 4 rotates one hundred and eighty degrees under the action of the steering mechanism, and the T-shaped block 6 slides to the other end of the semi-arc part corresponding to the T-shaped slot 7, while driving the cutting saw blade 3 to complete the steering. After the steering is completed, the T-shaped block 6 slides into the inclined part of the T-shaped slot 7 again, and drives the mounting plate 4 and the cutting saw blade 3 to rise, so that the cutting saw blade 3 is exposed in the cutting slot 2 so as to cut the plate.

[0019] Specifically, if Figure 2As shown, the transmission mechanism of this embodiment includes a pinion 20, which is fixedly mounted on the rotating shaft 5. The rotating shaft 5 and the cutting saw blade 3 are coaxially arranged. One side of the pinion 20 is meshed with a large gear 21, which is fixedly mounted on a transmission shaft 22. The two ends of the rotating shaft 5 are rotatably mounted on a support plate 23 via bearings. The support plate 23 is fixedly mounted on the mounting plate 4. The transmission shaft 22 is rotatably mounted on one side of the support plate 23. A first bevel gear 24 is fixedly mounted on the transmission shaft 22. The transmission shaft 22, the large gear 21, and the first bevel gear 24 are coaxially arranged. A second bevel gear 25 is meshed with one side of the first bevel gear 24, which is connected to the driving mechanism. When the driving mechanism is in operation, the second bevel gear 25 is driven to rotate. Then, through the transmission of the first bevel gear 24, the transmission shaft 22, and the large gear 21, the pinion 20 and the rotating shaft 5 are driven to rotate together, and finally, the cutting saw blade 3 is driven to rotate.

[0020] Specifically, such as Figure 1 、 Figure 2 、 Figure 3As shown, the driving mechanism described in this embodiment includes a motor 30, which is fixedly mounted on the processing table 1, and the output shaft of the motor 30 extends into the reserved hole on the processing table 1 and is fixedly connected to one end of the worm 31, and the output shaft of the motor 30 is rotatably connected to the inner wall of the reserved hole through a bearing, and the output shaft of the motor 30 is coaxially arranged with the worm 31, and the other end of the worm 31 is rotatably mounted in the processing table 1 through a bearing, and a first gear 32 is fixedly mounted on the worm 31, and a second gear 33 is meshed with one side of the first gear 32, and the second gear 33 is fixedly mounted on the reciprocating screw 34, and the reciprocating screw 34 is rotatably mounted in the processing table 1, and the two ends of the reciprocating screw 34 are rotatably mounted on the inner wall of the processing table 1 through bearings respectively. The first nut 35 is installed in cooperation with the thread on the lever 34, and the first nut 35 is coaxially arranged with the reciprocating screw 34. A circular ring 36 is installed on one side of the first nut 35, and a vertical shaft 37 is rotatably installed in the circular ring 36 through a bearing. A worm gear 38 is fixedly installed on the vertical shaft 37, and the worm gear 38 is engaged with the worm 31. One side of the worm gear 38 is fixedly connected to one end of the telescopic shaft 39, and the other end of the telescopic shaft 39 passes through the mounting plate 4 and is fixedly connected to the second bevel gear 25. The movable end of the telescopic shaft 39 is rotatably connected to the inner periphery of the through groove on the mounting plate 4 through a bearing, and the fixed end of the telescopic shaft 39 is fixedly connected to the worm gear 38. The circular ring 36, vertical shaft 37, worm gear 38, telescopic shaft 39, and second bevel gear 25 are coaxially arranged, and the axis passes through the center of the cutting saw blade 3. The operation of the motor 30 drives the worm 31 and the first gear 32 to rotate, which in turn drives the reciprocating screw 34 to rotate through the transmission of the second gear 33. The rotation of the worm 31 drives the worm wheel 38 to rotate, thereby driving the telescopic shaft 39 and the vertical shaft 37 to rotate along the ring 36. The rotation of the telescopic shaft 39 drives the second bevel gear 25 to rotate; the rotation of the reciprocating screw 34 causes the first nut 35 to move left or right along the reciprocating screw 24, thereby driving the ring 36, the vertical shaft 37, the worm wheel 38, and the telescopic shaft 39 to move left or right, and finally drives the mounting plate 4 to move left or right.

[0021] Further, such as Figure 1 、 Figure 2 、 Figure 3As shown, the steering mechanism described in this embodiment includes a spring rod 40, which is fixedly mounted on the mounting plate 4. The axis of the spring rod 40, the center of the mounting plate 4, and the T-shaped block 6 are located on the same radius of the mounting plate 4. The semi-arc groove portions corresponding to the two sides of the T-slot 7 in the processing table 1 are fixedly mounted with arc-shaped inclined plates 41, respectively. The arc-shaped inclined plates 41 on both sides are symmetrically distributed around the center, and the two ends of the arc-shaped inclined plates 41 are fixedly mounted on the inner wall of the processing table 1 by several connecting rods. The higher end of the arc-shaped inclined plate 41 corresponds to the inclined portion of the T-slot 7 as a horizontal plate. When the driving mechanism drives the mounting plate 4 to move, causing the T-shaped block 6 to slide into the inclined part of the T-shaped slot 7, the spring rod 40 moves to the upper side of the higher end of the arc-shaped inclined plate 41, and the mounting plate 4 drives the T-shaped block 6 to move along the inclined part of the T-shaped slot 7, the mounting plate 4 and the spring rod 40 move downward at the same time, and the spring rod 40 is compressed. Subsequently, the driving mechanism drives the mounting plate 4 and the T-shaped block 6 to move to the semi-arc part of the T-shaped slot 7, and the spring rod 40 slides to the inclined part of the arc plate 41. At this time, under the action of the elastic force of the spring rod 40, the spring rod 40 gives the arc-shaped inclined plate 41 a thrust, so that the arc-shaped inclined plate 41 gives the spring rod 40 a reaction force, so that the spring rod 40 has a tendency to rotate along the center of the circle of the arc plate 41, so that the spring rod 40 drives the mounting plate 4 and the T-shaped block 6 to rotate one hundred and eighty degrees, thereby driving the cutting saw blade 3 to rotate one hundred and eighty degrees, completing the turning of the cutting saw blade 3.

[0022] Furthermore, Figure 2 、 Figure 3 As shown, in this embodiment, a plurality of rollers 50 are rotatably mounted on the T-block 6, with the rollers 50 being rotatably mounted on the upper side, lower side, and right side of the T-block 6. The rollers 50 can convert the sliding friction between the T-block 6 and the T-slot 7 into rolling friction, which is more conducive to the sliding of the T-block 6.

[0023] Furthermore, Figure 3As shown, the two sides of the processing table 1 described in this embodiment are respectively rotatably installed with screw rods 60, and the two ends of the screw rod 60 are respectively rotatably installed on the processing table 1 through the shaft seat. The screw threads on both sides of the screw rod 60 are in opposite directions, and the two sides of the screw rod 60 are respectively threaded and installed with the second nut 61, and the second nut 61 is respectively fixedly installed with a clamping plate 62. When the clamping plate 62 is located on the top side of the processing table 1, the clamping plate 62 is in sliding contact with the top side of the processing table 1, which can prevent the second nut 61 from rotating with the screw rod 60. Rotating the screw rod 60 causes the second nut 61 on the same screw rod 60 to move in a direction close to each other, so that the clamping plate 62 clamps the plate, making it more stable during cutting; when the plate does not need to be cut, the clamping plate 62 is moved to rotate to the vertical direction and stored. In this state, the clamping plate 62 fits with the side of the processing table 1, which can Prevent the second nut 61 from rotating with the screw rod 60. Rotate the screw rod 60 to move the second nut 61 on the same screw rod 60 away from each other, thereby increasing the distance between the splints 62 on the same screw rod 60. This will facilitate adjustment of the distance between the splints 62 on the same screw rod 60 when the wood board is cut next time so that the splints 62 can be re-fitted with the top side of the processing table 1. When the board is clamped and the splints 6 are stored vertically, the top side of the processing table 1 can be used as a workbench, thereby increasing the practicality of the device.

[0024] Furthermore, Figure 5 As shown, in this embodiment, a T-shaped slider 70 is fixedly mounted on the circular ring 36, and a T-shaped slot 71 is defined on the first nut 35 corresponding to the T-shaped slider 70. The T-shaped slider 70 is slidably mounted within the T-shaped slot 71. Two sides of the T-shaped slider 70 are respectively fixedly connected to one end of a spring 72, and the other ends of the spring 72 are respectively fixedly connected to the inner wall of the T-shaped slot 71. When the T-block 6 moves into the semi-arc portion of the T-slot 7, the arrangement of the T-shaped slider 70 and the T-slot 71 allows the first nut 35 to continue moving, thereby giving the mounting plate 4 and the T-block 6 time to turn, ensuring that when the first nut 35 moves to the end of the thread of the reciprocating screw 34, the mounting plate 4 and the cutting saw blade 3 can complete the turn.

[0025] Furthermore, Figure 6 As shown, in this embodiment, coaxial hand wheels 80 are fixedly mounted on the screw rods 60. Rotating the screw rods 60 by the hand wheels 80 is more convenient and labor-saving.

[0026] Finally, it should be noted that 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
