Description

Technical Field

[0001] The present invention relates to the technical field of wood board cutting, and particularly relates to a wood cutting device for furniture manufacturing. Background Art

[0002] Furniture is composed of four factors: materials, structure, appearance form, and function. Among them, function is the leading factor and the driving force for the development of furniture; structure is the main body and the basis for realizing the function. Wooden furniture is a relatively common type in the current market. As the main material for manufacturing furniture, wood needs to be cut and processed during the furniture manufacturing process. The accuracy of wood cutting and processing plays a crucial role in the subsequent processes of manufacturing furniture from wood.

[0003] Currently, during the wood cutting and processing process, the wood is cut through the cooperation of a cutting tool and a pushing mechanism. During cutting, the thickness of the board cutting is manually controlled, and then the wood is pushed through the cutting tool to complete the cutting. During the wood cutting process, it is necessary to push the wood back and forth to complete a wood cutting process, which takes a long time. Moreover, during the return journey of the wood, the cutting tool is in an idle running state, resulting in energy consumption. During the process of cutting wood, the cut wood board is easily affected by factors such as tension and squeezes the cutting tool, affecting the service life of the cutting tool, and it is also easy to cause the situation where the wood gets stuck in the cutting tool and cannot work.

[0004] Based on this, in the existing situation of wood cutting, there is still room for improvement. Summary of the Invention

[0021] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings. However, the present utility model can be implemented in many different ways defined and covered by the claims.

[0022] As Figures 1 to 4 shown, a wood cutting device for furniture manufacturing includes a processing frame 1, a cutting frame 2 is arranged on the processing frame 1, a cutting knife for processing wood is arranged on the cutting frame 2, a pushing mechanism 3 is arranged on the processing frame 1 for adjusting and pushing the wood to be processed, the wood is processed by the cutting knife during movement, the number of auxiliary mechanisms 4 is two and they are symmetrically arranged on both sides of the cutting frame 2, and the auxiliary mechanisms 4 are connected to the processing frame 1, and the auxiliary mechanisms 4 are used for temporarily limiting and supporting the cut plates during operation.

[0023] By adopting the above technical solution, during operation, the wood to be cut is placed on the pushing mechanism 3, and the pushing mechanism 3 controls the movement of the wood towards the direction of the cutting knife. The pushing mechanism 3 automatically controls the width of the wood exceeding the cutting knife during operation, so as to accurately control the thickness of the wood cutting. Moreover, the pushing mechanism 3 can uniformly control the movement of the wood towards the working direction of the cutting knife, so that the cutting knife can smoothly cut the wood. The pushing mechanism 3 controls the reciprocating movement of the wood during operation. During this process, the pushing mechanism 3 and the cutting knife cooperate to cut the wood within the movement stroke of the wood, saving time and improving the cutting efficiency. The auxiliary mechanism 4 can be automatically adjusted during the wood cutting process. It can not only limit the wood during cutting operation to ensure the cutting thickness of the wood, but also support the wood during cutting operation, effectively preventing the situation that the cutting knife is stuck and unable to work due to factors such as tension during the cutting operation. In addition, the auxiliary mechanism 4 can automatically convey the cut wood during operation.

[0024] The pushing mechanism 3 includes a rectangular groove formed in the processing frame 1. A moving frame 31 is slidably arranged in the rectangular groove. Yielding grooves are formed at both ends of the moving frame 31. Push blocks 32 are arranged in the yielding grooves through torsion springs. Push grooves are symmetrically arranged on the upper end surface of the moving frame 31. Extrusion frames 33 are arranged in the push grooves through springs. A pushing chain is arranged on the processing frame 1. A control chain 34 is arranged at the inner wall of the lower end of the processing frame 1. The control chain 34 is connected to the moving frame 31. The control chain 34 controls the movement of the moving frame 31 in the rectangular groove during operation.

[0025] By adopting the above technical solution, the control chain 34 controls the position movement of the moving frame 31 during operation, so as to control the reciprocating movement of the wood on the moving frame 31. The pushing chain extrudes the wood placed on the moving frame 31 during operation, so as to control the thickness of the wood exceeding the cutting knife, and further control the cutting thickness of the wood.

[0026] When the wood needs to be retracted onto the moving frame 31, the control chain 34 drives the moving frame 31 to move towards the end where the wood is placed. During this process, the push block 32 is synchronously driven to move towards the boundary of the rectangular groove. When the push block 32 is squeezed by the boundary of the rectangular groove, it rotates towards the direction of the yielding groove, so that the push block 32 is in a hidden state. After the wood is pushed onto the moving frame 31, the pushing chain pushes the wood to the designated position. The control chain 34 starts to work and drives the wood to move towards the cutting knife. During this process, the push block 32 resets. When the wood contacts the cutting knife, the wood is blocked and squeezes the push block 32. The push block 32 will not rotate when being squeezed by the wood. By blocking the wood with the push block 32, the moving frame 31 can drive the wood to pass through the working cutting knife during movement, ensuring that the cutting knife can smoothly cut the wood.

[0027] The control chain 34 includes control shafts 341 symmetrically arranged between the inner walls of the processing frame 1. The control shafts 341 are arranged on the processing frame 1 through bearings. A control motor 342 is installed on the processing frame 1 through a motor seat. The output shaft of the control motor 342 is connected to the control shaft 341 through a coupling. Sprockets 343 are arranged on the control shafts 341. The two sprockets 343 are connected through a chain 344. The chain 344 is connected to the moving frame 31.

[0028] By adopting the above technical solution, the control motor 342 is started during operation. The control motor 342 drives the control shaft 341 to rotate during operation. During the rotation of the control shaft 341, the movement of the moving frame 31 is controlled through the cooperation between the chain 344 and the sprockets 343.

[0029] The pushing branch chain includes a pushing cylinder 331 installed on the processing frame 1. A pushing plate 332 is arranged on the pushing cylinder 331. Telescopic rods 333 are symmetrically arranged on the pushing plate 332, and the telescopic rods 333 are connected to the processing frame 1. The plane where the lower end of the pushing plate 332 is located is on the upper side of the pushing block 32.

[0030] By using the above technical solution, when it is necessary to adjust the cutting thickness of the wood during the operation, the pushing cylinder 331 is started to drive the pushing plate 332 to extrude the wood on the moving frame 31. The wood after being extruded moves towards the direction of the auxiliary mechanism 4. The cutting thickness of the wood is controlled through the mutual cooperation between the auxiliary mechanism 4 and the pushing branch chain.

[0031] The auxiliary mechanism 4 includes a mounting shaft 41 arranged between the processing frame 1 and the cutting frame 2 through bearings. A rotating motor 42 is installed on the processing frame 1 through a motor base. The output shaft of the rotating motor 42 is connected to the mounting shaft 41 through a coupling. An auxiliary frame 43 is installed on the mounting shaft 41, and an auxiliary branch chain is arranged inside the auxiliary frame 43.

[0032] The auxiliary branch chain includes an auxiliary support 44 slidably arranged inside the auxiliary frame 43. A cylinder is arranged between the auxiliary supports 44. Auxiliary rollers 45 are arranged on the auxiliary supports 44 at equal intervals through pins. The auxiliary rollers 45 are of cavity structure, and the auxiliary rollers 45 are connected to a vacuum pump through air pipes. Suction cups 46 are evenly arranged on the auxiliary rollers 45.

[0033] By adopting the above technical solution, during the operation, to ensure that the cutting thickness of the board meets the requirements, the rotating motor 42 is started to control the mounting shaft 41 to rotate so that the auxiliary frame 43 is adjusted to an angle parallel to the wood. Then the cylinder is started to drive the auxiliary support 44 to move towards the board, so that the auxiliary rollers 45 are attached to the wood. The auxiliary rollers 45 cooperate with the pushing branch chain during the wood cutting process to control the cutting thickness of the wood. The auxiliary rollers 45 limit and support the wood during the cutting movement. When the cut board is separated from the wood, the vacuum pump starts to work to suck and tighten the cut wood through the suction cups. Then the rotating motor 42 starts to rotate, and the rotating motor 42 moves the cut board away from the working position during the rotation.

[0034] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
