Description

Technical Field

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

[0002] In the field of wood processing, from the perspective of processing needs, the shapes and connection methods of wood products are becoming increasingly diversified. For example, making specially shaped wooden furniture, such as picture frames with beveled joints or wooden tables with slanted edges, requires cutting the wood at different angles. However, early fixed-angle cutting equipment could not meet these diverse processing needs. From the perspective of technological development, the market demand for equipment that can flexibly adjust the cutting angle is becoming increasingly urgent. This has prompted the incorporation of angle-adjustable functions into the design of wood processing equipment to better adapt to various complex wood processing tasks.

[0003] From the perspective of technological development, traditional cutting devices focus on improving cutting efficiency and precision, but do not adequately consider the flexibility of cutting angles. This leads to certain limitations in wood processing tools. Furthermore, wood will wobble during cutting due to the cutting force, and current wood processing devices on the market have difficulty fixing wood of different sizes, affecting the cutting efficiency.

[0004] In response to the technical problems of insufficient flexibility in cutting angle and difficulty in fixing wood of different sizes, this application proposes a wood cutting device with adjustable cutting angle. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wood cutting device with an adjustable cutting angle. This device can flexibly adjust the angle of the cutting blade to cut wood from different angles and can clamp and fix wood of different sizes, facilitating subsequent cutting operations.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A wood cutting device with adjustable cutting angle includes support frames fixedly connected to the left and right sides of the top of a support plate. A first motor is fixedly connected to one end of each support frame. The drive end of the first motor passes through the outer wall of the support frame and is fixedly connected to a lead screw. The front end of each lead screw is connected to a moving plate through a rotating component. A fixed frame is fixedly connected to the front end of each support frame.

[0008] A fixing rod is fixedly connected to the rear side of the top of the support plate. A toothed ring frame is fixedly connected to the top of the fixing rod. A sliding plate is slidably connected to the inner wall of the toothed ring frame. A cutting tool is connected to the front end of the sliding plate through a connecting assembly.

[0009] Furthermore, the rotating assembly includes a slider threadedly connected to the outer wall of the lead screw, both ends of the slider being slidably connected to the outer wall of the fixed frame, and a connecting rod being fixedly connected to the front end of the slider, with the moving plate sleeved on the outer wall of the connecting rod.

[0010] Furthermore, a rectangular groove is formed on the outer wall of the movable plate, and the diameter of the rectangular groove is the same as the diameter of the connecting rod.

[0011] Furthermore, the outer wall of the movable plate is rotatably connected to the outer wall of the fixed frame, and a clamping plate is fixedly connected to the outer side of the movable plate.

[0012] Furthermore, a second motor is fixedly connected to the inner wall of the sliding plate, and a spur gear is fixedly connected to the drive end of the second motor. The outer diameter of the spur gear meshes with the outer diameter of the gear ring frame.

[0013] Furthermore, the connecting assembly includes an electric push rod fixedly connected to the front end of the sliding plate, and a cutting tool is fixedly connected to the telescopic end of the electric push rod.

[0014] Furthermore, a base frame is fixedly connected to the bottom end of the support plate, and the base frame is used to support the support plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the angle of the cutting tool can be flexibly adjusted by the cooperation of the spur gear and the gear ring frame. By adjusting the cutting angle, various beveled and inclined shapes can be obtained, so that the product meets diverse design requirements, improves the product's refinement and adaptability, and increases the overall production speed.

[0017] 2. In this utility model, the movement of the clamping plate is driven by the rotation of the slider on the lead screw, which can clamp and fix wood of different sizes. Stable clamping of wood of different sizes helps to ensure the accuracy of cutting operations, reduce time waste caused by frequent tool changes, and increase the versatility of the device.

[0028] Specifically, the upper and lower sides of the slider 6 slide on the fixed frame 5, which provides support for the sliding of the slider 6. The clamping plate 9 consists of a horizontal long plate and a vertical short plate. The clamping plate 9 is treated with anti-slip material, which can clamp the wood more stably.

[0029] Reference Figures 4-6A fixed rod 10 is fixedly connected to the rear side of the top of the support plate 1. A toothed ring frame 11 is fixedly connected to the top of the fixed rod 10. A sliding plate 12 is slidably connected to the inner wall of the toothed ring frame 11. An electric push rod 15 is fixedly connected to the front end of the sliding plate 12. A cutting tool 16 is fixedly connected to the telescopic end of the electric push rod 15. A second motor 13 is fixedly connected to the inner wall of the sliding plate 12. A spur gear 14 is fixedly connected to the drive end of the second motor 13. The outer diameter of the spur gear 14 meshes with the outer diameter of the toothed ring frame 11. A base frame 18 is fixedly connected to the bottom end of the support plate 1. The base frame 18 is used to support the support plate 1.

[0030] Specifically, the second motor 13 is installed on the inner wall of the sliding plate 12. The driving end of the second motor 13 is fixedly connected to a driving rod, which drives the spur gear 14 to rotate. The gear ring frame 11 is formed by connecting two upper and lower outer gear rings. The cutting tool 16 is controlled by a stepper motor inside the cutting tool 16.

[0031] Working principle: When cutting wood of different sizes, the first motor 3 is started to drive the lead screw 4 to rotate, causing the slider 6 to slide on the lead screw 4. The slider 6 drives the connecting rod 7 to move, and the connecting rod 7 drives the moving plate 8 sleeved on the connecting rod 7 to move. One end of the moving plate 8 rotates on the fixed frame 5, thereby causing the moving plate 8 to drive the clamping plate 9 to move, clamping and fixing wood of different diameters. After the wood is clamped and fixed, the second motor 13 inside the sliding plate 12 is started to drive the two spur gears 14 to rotate. Due to the action of the gear ring frame 11, the spur gears 14 will rotate along the gear ring frame 11, thereby driving the sliding plate 12 to rotate along the gear ring frame 11. The sliding plate 12 drives the electric push rod 15 and the cutting tool 16 to move. Starting the electric push rod 15 can adjust the distance between the cutting tool 16 and the wood, making it easier to cut the wood.
