Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood cutting technology, specifically to a cutting device for chair processing. Background Technology
[0002] In the process of manufacturing chairs, the chair materials need to be processed first. Most chairs are made of wood. In the process of making chairs, the wood needs to be cut into the required shape. The cutting device used in the cutting process is crucial, as it relates to the accuracy and efficiency of wood cutting.
[0003] Most existing wood cutting devices can only cut into relatively conventional shapes such as squares or circles, and cannot cut irregularly shaped chair parts with different curvatures, which limits their use. Wood chips and dust are generated during the chair cutting process, and many cutting devices do not have a dust cleaning structure. As a result, if they are not cleaned in time, they will accumulate on the workbench, which can affect the cutting efficiency. It is also not convenient to mark and measure the cutting dimensions of the chair, and the fixing and clamping of the wood during cutting is not convenient enough. Utility Model Content

The following will refer to the accompanying drawings. Figures 1-4 The present invention will be described in detail with reference to the embodiments.
[0023] A cutting device for chair processing includes a workbench 1. A cutting pad 20 is fixedly mounted on the tabletop of the workbench 1 to facilitate the cutting of wood by a vibrating blade 12. The cutting pad 20 is provided with scale markings 21, which allow for clear observation of the cutting dimensions of the wood. A set of vertical plates 2 are provided on the tabletop of the workbench 1. One vertical plate 2 has a fixing component 3 and a reciprocating lead screw 4 on its inner side, while the other vertical plate 2 has an elastic layer 5 and a guide groove 6 on its inner side. The fixing component 3, in conjunction with the opposite vertical plate 2, can clamp and hold the wood in place.
[0024] A set of support blocks 22 are fixedly installed on the inner wall of the vertical plate 2 above the fixed component 3. A motor 23 is installed on the outer wall of one of the support blocks 22 through a mounting bracket. A reciprocating screw 4 is rotatably installed between the support blocks 22 and is fixedly connected to the output shaft of the motor 23. When the motor 23 is started, the reciprocating screw 4 can be driven to rotate.
[0025] Since the reciprocating screw 4 is threaded and the top plate 7 is slidably provided on the guide groove 6, and the guide groove 6 is parallel to the reciprocating screw 4, one end of the top plate 7 is threaded and provided on the outer periphery of the thread of the reciprocating screw 4, and the other end is slidably provided on the guide groove 6, the rotation of the reciprocating screw 4 will drive the top plate 7 to move back and forth along the direction of the reciprocating screw 4 and the guide groove 6.
[0026] The top wall of the top plate 7 is equipped with a vacuum cleaner 8 and a control panel 9. The bottom wall of the top plate 7 is rotatably equipped with a reciprocating screw 10. The reciprocating screw 10 is threadedly connected to a telescopic rod 11. The bottom wall of the top plate 7 is fixedly equipped with another set of support blocks 22. One of the support blocks 22 has a motor 24 mounted on its outer wall via a mounting bracket. The reciprocating screw 10 is rotatably mounted between the support blocks 22 and is fixedly connected to the output shaft of the motor 24. The outer wall of the reciprocating screw 10 is threadedly connected to a movable seat 25. The bottom wall of the top plate 7 is also fixedly equipped with a guide groove 6. The top of the movable seat 25 can move within the guide groove 6. The telescopic rod 11 is fixedly mounted on the bottom wall of the movable seat 25.
[0027] Start motor 24 to drive reciprocating screw 20 to rotate, which in turn drives moving seat 25 to move left and right along reciprocating screw 20 under the guidance of guide groove 6. This in turn drives telescopic rod 11 to move left and right. Since the telescopic bottom end of telescopic rod 11 is fixedly provided with connecting plate 26, and the bottom wall of connecting plate 26 is fixedly provided with vibrating knife 12, the vibrating knife 12 can move freely according to the cutting scheme preset by control panel 9, with the cooperation of reciprocating screw 14 and reciprocating screw 20, and can cut wood into various required shapes.
[0028] A dust collection hood 13, which communicates with a vacuum cleaner 8, is fixedly installed on the side of the vibrating blade 12. The dust collection hood 13 is also fixedly installed on the side wall of the connecting plate 26 via a fixing ring 27. The dust collection hood 13 is connected to the vacuum cleaner 8 via a telescopic hose 28. During the cutting process, the vacuum cleaner 8 can be started simultaneously, allowing debris and dust to be sucked up by the dust collection hood 13, drawn into the telescopic hose 28, and transported to the vacuum cleaner 8 for centralized collection. This facilitates centralized processing and prevents dust and debris from accumulating on the table, which would affect cutting efficiency.
[0029] The number of fixing components 3 is three sets, including a telescopic rod 14 fixedly installed on the inner side wall of the vertical plate 2. A clamping plate 15 is fixedly installed at the telescopic end of the telescopic rod 14. A cavity 18 is provided inside the clamping plate 15. A reciprocating screw 16 is rotatably installed inside the cavity 18. A pressure plate 17 is threadedly connected to the outer wall of the reciprocating screw 16. An elastic layer 5 is also provided on the bottom wall of the pressure plate 17. The elastic layer 5 is a sponge layer or a rubber layer that will not damage the wood surface. A knob 19 is fixedly installed at the top of the reciprocating screw 16.
[0030] First, place the wood to be cut on the workbench 1, with one end close to the elastic layer 5 on the inner side of the vertical plate 2, and the other end fixed and clamped by the fixing component 3. Activate the telescopic rod 14, which will move the clamping plate 15 close to the side wall of the wood until it is in close contact with the side wall of the wood and then stop extending. At this time, rotate the knob 19, which will drive the reciprocating screw 16 to rotate, thereby allowing the pressure plate 17 to move downward until the elastic layer 5 is close to the top wall of the wood below, thus clamping and fixing the wood.
[0031] The control panel 9 is electrically connected to the vacuum cleaner 8, vibrating blade 12, telescopic rod 2 14, motor 1 23, motor 2 24, and telescopic rod 1 11. The desired chair shape can be preset on the control system within the control panel 9, and the wood will be automatically cut according to the cutting instructions, improving efficiency and saving manpower.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
