Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a wood cutting device. Background Technology

[0002] Wood panels, as a basic material, are widely used in the manufacture of various types of furniture, including but not limited to wardrobes, cabinets, doors, tables, and chairs. However, precise cutting of the wood panels is a crucial step before these pieces of furniture can be made.

[0003] To ensure the accuracy of the dimensions of the cut wooden planks, a crucial step in traditional craftsmanship is the meticulous measurement and marking of the planks. This process not only ensures that the furniture's dimensions meet design requirements but also serves as a prerequisite and foundation for subsequent precise cutting. Unfortunately, this seemingly simple step faces numerous challenges in practice.

[0004] First, the measurement and marking process is quite time-consuming, especially when furniture production requires batch processing. The time cost of this step is particularly significant, greatly hindering production efficiency. Second, workers need to frequently change positions while measuring and marking, which undoubtedly increases their workload and makes the entire production process more cumbersome. More importantly, to ensure marking accuracy, workers must be fully focused and meticulous. While this high level of concentration may be maintained for a short time, it easily leads to mental fatigue over time, potentially affecting the accuracy of subsequent cutting and the overall quality of the furniture.

[0005] Therefore, it is necessary to develop a wood cutting device to address the aforementioned shortcomings. Utility Model Content

[0031] The core of this utility model is to provide a wood board cutting device that eliminates the need for measuring and marking the wood board during cutting, thereby improving production efficiency, reducing the labor intensity of workers, and avoiding mental fatigue caused by prolonged periods of high concentration.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In one specific embodiment of this utility model, a workbench 1 is included, on which a cutting assembly for cutting wooden boards 2 is installed. A distance-fixing assembly is also included, located on one side of the material output end of the cutting assembly. The distance-fixing assembly includes a positioning slider 3, a first telescopic rod 4, a positioning block 5, a gantry frame 6, a ruler 7, and a driving assembly. Two gantry frames 6 are fixed on the workbench 1, and the driving assembly is installed on the two gantry frames 6. The driving assembly is connected to the positioning slider 3 and can drive the positioning slider 3 to move closer to or away from the cutting assembly. The first telescopic rod 4 is vertically fixed to the bottom end of the positioning slider 3. The positioning block 5 is located between the first telescopic rod 4 and the workbench 1, and is fixedly connected to the telescopic end of the first telescopic rod 4. The ruler 7 is installed between the two gantry frames 6, and an indicator block 301 for indicating the scale lines of the ruler 7 is fixed on the positioning slider 3.

[0035] Specifically, the first telescopic rod 4 and the second telescopic rod 27 can be pneumatic cylinders, hydraulic cylinders, or electric cylinders. The top of the worktable 1 can be a flat plate or a hollow structure. A rotating roller 101 can be installed on the hollow structure. Compared with a flat plate, the rotating roller 101 can reduce the resistance when the wooden board 2 is fed.

[0036] In one specific embodiment of this utility model, the drive assembly includes a first reduction motor 8, a first screw 9, and a first guide rod 10. The first screw 9 is rotatably mounted on two gantry frames 6, and the first guide rod 10 is fixedly mounted on two gantry frames 6. The first reduction motor 8 is fixedly connected to any one of the gantry frames 6, and the output shaft of the first reduction motor 8 is fixedly connected to one end of the first screw 9. The first screw 9 rotatably passes through the positioning slider 3, and the first screw 9 is threadedly connected to the positioning slider 3. The first guide rod 10 slides through the positioning slider 3.

[0037] Specifically, the distance between the positioning block 5 and the saw blade 23 is the value indicated on the ruler 7 by the indicator block 301, which is the size of the wood board to be cut. The distance between the positioning block 5 and the saw blade 23 is adjusted by the first reduction motor 8. When the value indicated by the indicator block 301 is the required size, the first reduction motor 8 stops working. The first reduction motor 8 drives the first screw 9 to rotate, and the screw 9 drives the positioning slider 3 to slide on the first guide rod 10. The positioning slider 3 drives the first telescopic rod 4 and the positioning block 5 to move synchronously. When the first reduction motor 8 rotates forward, the positioning slider 3 moves away from the cutting component. When the first reduction motor 8 rotates in reverse, the positioning slider 3 moves towards the cutting component.

[0038] In one specific embodiment of this utility model, a horizontally arranged fixing rod is fixedly connected between the two gantry frames 6, and a ruler 7 is fixed on the upper surface of the fixing rod.

[0039] Specifically, the fixing rod is used to support the ruler 7 and prevent the ruler 7 from bending; the ruler 7 can be bolted or glued to the fixing rod for easy replacement.

[0040] In one specific embodiment of this utility model, a feeding assembly is also included, located on one side of the feed end of the cutting assembly and used for conveying the wooden board 2. The feeding assembly includes a feeding shaft 12, a feeding motor 13, and a rubber sleeve 14. Two fixed plates are fixed on the worktable 1. The feeding shaft 12 is rotatably mounted on the two fixed plates. The rubber sleeve 14 is fixedly sleeved on the feeding shaft 12, and the circumferential surface of the rubber sleeve 14 abuts against the upper surface of the wooden board 2. The bottom surface of the wooden board 2 rests on the worktable 1. The feeding motor 13 is fixedly connected to either of the fixed plates, and the output shaft of the feeding motor 13 is fixedly connected to one end of the feeding shaft 12. Specifically, the rubber sleeve 14 can be glued or bolted to the feeding shaft 12. By conveying the wooden board 2 through the feeding assembly, the workers do not need to push the wooden board 2, reducing the labor intensity of the workers.

[0041] In one specific embodiment of this utility model, the distance fixing component also includes a sensor 11 for sensing the wooden board 2. A through hole is provided on the positioning block 5, and the sensor 11 is fixedly connected to the through hole. The sensing end of the sensor 11 faces the wooden board 2.

[0042] Specifically, sensor 11 can be a distance sensor, a contact switch, a vision camera, etc., as long as it can send a signal to an externally set controller when the wooden board 2 contacts the positioning block 5. The feed motor 13 drives the feed shaft 12 to rotate, and the feed shaft 12 drives the rubber sleeve 14 to rotate synchronously. The rubber sleeve 14 drives the wooden board 2 to feed through friction. When the wooden board 2 contacts the positioning block 5, sensor 11 sends a signal to the controller that the wooden board 2 has reached its position. After receiving the signal, the controller controls the feed motor 13 to stop working.

[0043] In addition, in order to facilitate the feeding of the wooden board 2 and reduce the feeding resistance, multiple rotating rollers 101 are provided on the worktable 1, and the rotating rollers 101 are distributed on both sides of the cutting assembly, with the wooden board 2 supported on the rotating rollers 101.

[0044] In one specific embodiment of this utility model, a guide assembly for guiding the wooden board 2 is also included. The guide assembly includes a U-shaped frame 15 and guide wheels 16. The U-shaped frame 15 is located on the side of the feed assembly away from the cutting assembly and is fixedly connected to the worktable 1. The guide wheels 16 are fixed inside the U-shaped frame 15, and two guide wheels 16 are provided, each contacting one side of the wooden board 2. The guide wheels 16 guide the wooden board 2, ensuring that the wooden board 2 maintains a straight line during feeding and avoiding skewing or shaking.

[0045] Obviously, the guide wheel 16 can be bolted to the U-shaped frame 15, which facilitates disassembly and assembly, and allows adjustment of the distance between the two guide wheels 16, thus guiding wooden boards 2 of different widths.

[0046] In one specific embodiment of this utility model, a clamping assembly is further included, located between the feeding assembly and the cutting assembly, for pressing the wooden board 2. The clamping assembly includes a second telescopic rod 27, an upper pressure bar 26, and a lower pressure bar 24. The lower pressure bar 24 is fixedly mounted on the worktable 1, and the distance between the bottom surface of the wooden board 2 and the top surface of the lower pressure bar 24 is zero. The upper pressure bar 26 is located directly above the lower pressure bar 24. A support assembly is fixedly connected to both the lower pressure bar 24 and the worktable 1. The second telescopic rod 27 is vertically fixed on the support assembly. There are two second telescopic rods 27, and the telescopic ends of the two second telescopic rods 27 are respectively fixedly connected to the two ends of the upper pressure bar 26. Specifically, by extending and retracting the second telescopic rod 27, the upper pressure bar 26 and the lower pressure bar 24 press the wooden board 2, ensuring that the wooden board 2 remains stable during the cutting process and improving the cutting accuracy.

[0047] In one specific embodiment of this utility model, the support assembly includes a vertical plate 25, a vertical plate 28, and a horizontal plate 29. The vertical plate 28 is integrally formed at the bottom end of the lower pressure strip 24, and its bottom end is fixedly connected to the horizontal plate 29. Vertical plates 25 are fixed to both ends of the horizontal plate 29. The vertical plates 25 are located outside the workbench 1, and a connecting column 102 is fixedly connected between the vertical plate 25 and the workbench 1. A second telescopic rod 27 is fixedly connected to the vertical plate 25. Specifically, the connecting column 102 is mainly used to enhance the stability of the vertical plate 25.

[0048] In one specific embodiment of this utility model, the cutting assembly includes a second reduction motor 17, a second screw 18, a second guide rod 19, a drive block 20, a connecting plate 21, a cutting motor 22, and a saw blade 23. The second screw 18 is rotatably mounted on the top of two upright plates 25, and the second guide rod 19 is fixedly mounted on the top of two upright plates 25. The second reduction motor 17 is fixedly connected to either upright plate 25, and the output shaft of the second reduction motor 17 is fixedly connected to one end of the second screw 18. The second guide rod 19 slides through the drive block 20, and the second screw 18 rotates through the drive block 20, and the second screw 18 is threadedly connected to the drive block 20. The connecting plate 21 is fixed to the bottom of the drive block 20, and the cutting motor 22 is fixed to one side of the connecting plate 21. The output shaft of the cutting motor 22 rotates through the connecting plate 21 and is fixedly connected to the saw blade 23. The upper pressure bar 26 and the lower pressure bar 24 are located on the side of the saw blade 23 away from the cutting motor 22.

[0049] The working principle of the wood cutting device of this utility model is as follows: the first reduction motor 8 drives the positioning slider 3 to move closer to or away from the cutting component by rotating forward and reverse, thereby driving the positioning block 5 to move to adjust its distance from the saw blade 23. This distance value is determined by the scale line of the ruler 7 indicated by the indicator block 301, which is the size of the wood board to be cut.

[0050] In use, first adjust the position of the positioning block 5: the first reduction motor 8 drives the first screw 9 to rotate, the first screw 9 drives the positioning slider 3 to slide on the first guide rod 10, the positioning slider 3 drives the first telescopic rod 4 and the positioning block 5 to move synchronously. When the value indicated by the indicator block 301 is the required size, the first reduction motor 8 stops working. The distance between the positioning block 5 and the saw blade 23 is the value indicated by the ruler 7 indicated by the indicator block 301, which is the size of the wooden board to be cut.

[0051] After adjusting the position of the positioning block 5, the telescopic end of the first telescopic rod 4 drives the positioning block 5 to descend, placing the wooden board 2 on the rotating roller 101, and positioning one end of the wooden board 2 between the rubber sleeve 14 and the rotating roller 101. The feed motor 13 is started, and the feed motor 13 drives the feed shaft 12 to rotate. The feed shaft 12 drives the rubber sleeve 14 to rotate synchronously. The rubber sleeve 14 drives the wooden board 2 to be fed through friction. When the wooden board 2 contacts the positioning block 5, the sensor 11 sends a signal that the wooden board 2 has reached its position to the externally set controller. After receiving the signal, the controller controls the feed motor 13 to stop working.

[0052] After the wooden board 2 is in place, the telescopic end of the second telescopic rod 27 drives the upper pressure bar 26 to descend, thereby causing the upper pressure bar 26 and the lower pressure bar 24 to cooperate with each other to clamp the wooden board 2.

[0053] At this time, the second reduction motor 17 and the cutting motor 22 are started. The cutting motor 22 drives the saw blade 23 to rotate, and the second reduction motor 17 drives the second screw 18 to rotate. The second screw 18 drives the drive block 20 to slide from one end of the second guide rod 19 to the other end. The cutting motor 22 and the saw blade 23 move synchronously with the drive block 20, and the saw blade 23 cuts the wooden board 2.

[0054] After the cutting is completed, the telescopic end of the first telescopic rod 4 drives the positioning block 5 to rise, and removes the cut wooden board from the workbench 1.

[0055] After the cut wooden board is removed, the telescopic end of the first telescopic rod 4 causes the positioning block 5 to descend again. At the same time, the telescopic end of the second telescopic rod 27 causes the upper pressure strip 26 to rise, and the feed motor 13 is started again. The rubber sleeve 14 drives the wooden board 2 to feed through friction. This cycle is repeated to cut the entire wooden board 2 multiple times.

[0056] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other.
