Description

Technical Field

[0001] The utility model relates to the technical field of wood cutting, in particular to a wood cutting device for the production of desks and chairs. Background Art

[0002] When processing wooden desks and chairs, cutting equipment is needed to cut the wood. When cutting the wood, sawdust is easily generated. The sawdust is thrown outwards with the rotation of the cutting blade and suspended in the air, which not only easily pollutes the environment, but also the operator inhales the air with dust, which stimulates the respiratory tract and easily causes respiratory diseases. The traditional cutting equipment is provided with a protective cover outside the cutting blade. The protective cover can block the diffusion of a part of the sawdust, but some small particles of sawdust cannot be blocked and will still diffuse into the air.

[0003] CN 221136206 U discloses a cutting device for processing desks and chairs with a dust removal component, including a cutting table. An activity frame is movably arranged on the top of the cutting table. A cutting device is arranged in the inner cavity of the activity frame. A support plate is fixed on the top of the cutting device, etc. The cutting device of the above utility model is installed in the activity frame, and then the activity frame is used to cover the cutting environment. Then, baffles that can move up and down are arranged on both sides of the activity frame. By fitting the baffles with the wood, the two sides of the activity frame are prevented from communicating with the outside. At the same time, the movement of the cutting device drives the coil to move to block the through groove, preventing the generated debris from diffusing outwards through the through groove. Then, an induced draft fan is arranged in the cutting table to generate an air pressure difference in the funnel, and the dust debris on the top of the cutting table is sucked into the fixed box through the blanking hole, which can effectively prevent the diffusion of dust and ensure the cleanliness of the processing environment for desks and chairs.

[0004] However, the baffle of the above utility model only falls freely by gravity. During the operation of the equipment, vibrations will occur, which will cause gaps to be generated between the baffle and the cutting table or the board. Small particles of sawdust will still diffuse from the gaps to the outside of the activity frame and pollute the processing environment. And every time when cutting the board, the position of the activity frame needs to be fixed again, which affects the processing efficiency. Summary of the Utility Model

[0005] In order to overcome the above defects existing in the prior art, the utility model provides a wood cutting device for the production of desks and chairs.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A wood cutting device for the production of desks and chairs, including a workbench, on which a dust-proof cover is fixedly installed. On the front and rear sides of the dust-proof cover, a number of groups of dust-proof plates are installed in a liftable manner. On the top of the dust-proof cover, baffle driving mechanisms are symmetrically installed front and rear. The baffle driving mechanism includes a driving box, and the dust-proof plate is movably installed at the bottom of the driving box. An air duct is opened inside the driving box, and an electromagnet is fixedly installed above the air duct.

[0007] Furthermore, in the middle of the top end of the dust-proof cover, a number of groups of fixing frames are fixedly installed. At the front and rear ends of the fixing frames, driving boxes are fixedly installed. At the bottom of the driving box, a number of groups of working cavities are provided. The number of the working cavities is consistent with the number of the dust-proof plates. A piston ring is movably installed in the working cavity. At the center of the piston ring, a connecting rod is fixedly installed. The bottom end of the connecting rod is fixedly connected to the dust-proof plate.

[0008] Furthermore, a number of groups of the working cavities are respectively communicated with the air duct. At the left and right ends of the air duct, air pipe joints are fitted. An exhaust valve is fitted on any one of the left and right air pipe joints.

[0009] Furthermore, a number of groups of through holes are provided between the air duct and the electromagnet. The position of each through hole corresponds to each connecting rod.

[0010] Furthermore, a cutting groove is opened on the inner table surface of the workbench inside the dust-proof cover. The cutting groove is horizontally arranged left and right. A number of groups of blanking holes are provided on the front and rear sides of the cutting groove.

[0011] Furthermore, a measuring ruler is fixedly installed on the front side wall of the dust-proof cover. The measuring ruler is flush with the leftmost dust-proof plate.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. In the design scheme of the present utility model, through the design that baffle driving mechanisms are symmetrically installed front and rear on the top of the dust-proof cover, air is injected into the driving box by an air pump. Under the action of air pressure, the dust-proof plate is pushed downward, so as to avoid generating gaps between the dust-proof plate and the workbench or the plate, and further prevent small particle sawdust from diffusing to the outside of the dust-proof cover through the gaps to pollute the processing environment.

[0014] 2. In the design scheme of the present utility model, through the design that an electromagnet is installed inside the dust-proof cover, when cutting the plate, the inside of the driving box is depressurized, and at the same time the electromagnet is powered on. The dust-proof plate is sucked upward by the electromagnet, so that the plate can enter the dust-proof cover from below the dust-proof plate for cutting, effectively improving the processing efficiency.

[0023] In order to more clearly illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the present utility model. For those of ordinary skill in the art, without creative efforts, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present utility model.

[0024] According to Figure 1-6 As shown, a wood cutting device for production of desks and chairs includes a workbench 1, on which a dust-proof cover 2 is fixedly installed. A plurality of groups of dust baffles 3 are installed on the front and rear sides of the dust-proof cover 2 in a liftable manner. Baffle driving mechanisms are symmetrically installed on the front and rear of the top of the dust-proof cover 2. The baffle driving mechanism includes a driving box 4. The dust baffle 3 is movably installed at the bottom of the driving box 4. An air duct 5 is opened inside the driving box 4, and an electromagnet 6 is fixedly installed above the air duct 5.

[0025] In this embodiment, several groups of fixing frames 7 are fixedly installed in the middle of the top end of the dust-proof cover 2. The front and rear ends of the fixing frames 7 are fixedly installed with driving boxes 4. Several working cavities 8 are provided at the bottom of the driving boxes 4. The number of the working cavities 8 is consistent with the number of the dust-proof plates 3. A piston ring 9 is movably installed in the working cavity 8. A connecting rod 10 is fixedly installed at the axis center of the piston ring 9. The bottom end of the connecting rod 10 is fixedly connected to the dust-proof plate 3.

[0026] In this embodiment, several working cavities 8 are respectively communicated with the air ducts 5. Air pipe connectors 11 are fitted and installed at the left and right ends of the air ducts 5. An exhaust valve 12 is fitted and installed on the air pipe connector 11 on the right side of the air duct 5. The air pipe connector 11 is connected to an air pump. Gas enters the driving box 4 from the end without the exhaust valve 12 installed, and the gas is discharged from the driving box 4 by opening the exhaust valve 12.

[0027] In this embodiment, several through holes 13 are provided between the air ducts 5 and the electromagnets 6. The position of each group of through holes 13 corresponds to each group of connecting rods 10 one by one. When the electromagnet 6 is electrified, the connecting rod 10 is adsorbed into the through hole 13 and contacts the electromagnet 6, so that the dust-proof plate 3 is lifted.

[0028] In this embodiment, a cutting groove 14 is provided on the inner side tabletop of the workbench 1 in the dust-proof cover 2. The cutting groove 14 is horizontally arranged left and right. Several material dropping holes 15 are provided on the front and rear sides of the cutting groove 14. A cutting device and a dust suction device are installed inside the workbench 1. The saw blade moves along the cutting groove 14 in the dust-proof cover 2 to cut the plate. The sawdust generated during cutting is sucked into the inside of the workbench 1 through the material dropping holes 15 for collection.

[0029] In this embodiment, a measuring rule 16 is fixedly installed on the front side wall of the dust-proof cover 2. The measuring rule 16 is flush with the leftmost dust-proof plate 3. The plate is positioned through the measuring rule 16, and the plate is conveyed into the dust-proof cover 2 along the measuring rule 16 under the push of the feeding mechanism for cutting.

[0030] When the present utility model is in use, first, the exhaust valve 12 is in an open state. The electromagnet 6 is electrified to suck up the dust-proof plate 3 through the connecting rod 10, so as to facilitate the plate to enter the dust-proof cover 2 from below the dust-proof plate 3 for cutting. When starting to cut the plate, the exhaust valve 12 is closed, and air is injected into the driving box 4 through an air pump. Under the action of air pressure, the piston ring 9 is pushed towards the bottom of the working cavity 8. Driven by the piston ring 9, the dust-proof plate 3 moves downward to closely adhere to the plate or the workbench 1, thereby preventing a gap from being generated between the dust-proof plate 3 and the workbench 1 or the plate, and further preventing small-particle sawdust from diffusing to the outside of the dust-proof cover 2 to pollute the processing environment.
