[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a dust-proof cutting device for processing wooden bottom support accessories, including a raw material conveying structure and a dust-proof cutting structure. The raw material conveying structure can be a belt conveyor in the prior art. The raw material conveying structure includes a conveyor mesh belt 2. When the device is in use, the raw materials to be cut are conveyed by the conveyor mesh belt 2.

[0025] The dust-proof cutting structure includes a protective cover 1. A load-bearing mesh plate 18 is fixedly connected inside the cavity of the protective cover 1. The load-bearing mesh plate 18 divides the cavity of the protective cover 1 into a cutting cavity and a waste residue collection cavity from top to bottom. Raw material inlets and outlets are provided on both sides of the cutting cavity. The conveyor mesh belt 2 is movably connected to the inner cavity of the raw material inlets and outlets. The bottom of the straight part of the conveyor mesh belt 2 contacts the top of the load-bearing mesh plate 18. The lower straight part of the conveyor mesh belt 2 is located below the protective cover 1. Thus, when the raw material conveying structure works, the raw materials for producing wooden bottom support accessories can be conveyed by the conveyor mesh belt 2 into the cutting cavity. And the load-bearing mesh plate 18 includes a mesh plate body, and the gaps between adjacent two mesh plate bodies form cutting grooves; the conveyor mesh belt 2 includes a mesh belt body, and the gaps between adjacent two mesh belt bodies form cutting grooves.

[0026] A dense curtain 3 is hung outside the raw material inlets and outlets. The dense curtain 3 is evenly provided with air holes. The dense curtain 3 includes curtain belts. Adjacent two curtain belts contact each other. The bottom of the curtain belt contacts the top of the conveyor mesh belt 2. And the curtain belt is evenly provided with air holes. The curtain belt is in a net shape and can intercept cutting debris. A counterweight block is arranged at the bottom of the curtain belt. Through the setting of the dense curtain 3, the debris generated during the cutting process can be intercepted, and the outside air can enter the cutting cavity through the air holes.

[0027] At both ends on one side of the cutting chamber, there are raw material limiting structures. The raw material limiting structures include a first hydraulic telescopic rod 14 fixedly connected to the protective cover 1. The end of the output shaft of the first hydraulic telescopic rod 14 is fixedly connected with a connecting frame 16. The other end of the connecting frame 16 is connected with a limiting roller 17. Through the setting of the first hydraulic telescopic rod 14, the telescopic movement of the first hydraulic telescopic rod 14 can change the position of the limiting roller 17. The combined use of the two limiting rollers 17 can limit the position of the raw material in the cutting chamber and ensure the cutting accuracy of the raw material.

[0028] At the top of the cutting chamber, there is a cutting structure. The cutting structure is connected to the protective cover 1 through a translation structure. In some embodiments of the present application, the translation structure includes a ball screw 8 movably connected to the top of the inner cavity of the protective cover 1 and a servo motor 9 fixedly connected to the protective cover 1. The outer ring of the ball screw 8 is threadedly connected with a ball nut 10. The bottom of the ball nut 10 is connected with a second hydraulic telescopic rod 11. The end of the output shaft of the servo motor 9 is fixedly connected with one end of the ball screw 8 through a speed reducer. Through the setting of the servo motor 9, the rotation of the servo motor 9 can drive the ball screw 8 fixedly connected thereto to rotate. The rotation of the ball screw 8 enables the ball nut 10 to move in the direction where the ball screw 8 is located. When the ball nut 10 moves, it can drive the second hydraulic telescopic rod 11 fixedly connected thereto to move.

[0029] The end of the output shaft of the second hydraulic telescopic rod 11 is fixedly connected with a tool holder 13. On the side of the tool holder 13 close to the raw material limiting structure, a cutting saw blade 12 is fixedly connected. The telescopic movement of the second hydraulic telescopic rod 11 can change the position of the cutting saw blade 12. When the cutting saw blade 12 moves repeatedly, the cutting of the wood raw material can be realized.

[0030] On the other side of the cutting chamber, there is a cleaning structure. The cleaning structure includes a third hydraulic telescopic rod 6 connected to the protective cover 1 and a cleaning brush 7 fixedly connected to the end of the output shaft of the third hydraulic telescopic rod 6. Through the setting of the third hydraulic telescopic rod 6, the telescopic movement of the third hydraulic telescopic rod 6 can change the position of the cleaning brush 7 fixedly connected thereto. When the equipment is in use, the cleaning brush 7 contacts the top of the raw material. When the third hydraulic telescopic rod 6 drives the cleaning brush 7 to move, the cleaning brush 7 can sweep away the cutting debris falling on the top of the raw material, which is convenient for the subsequent processing of the raw material.

[0031] A collection mesh frame 19 is placed inside the inner cavity of the waste residue collection chamber. And on both sides of the bottom of the inner cavity of the waste residue collection chamber, there are limiting blocks 20 fixedly connected. The bottom of the collection mesh frame 19 contacts the top of the limiting blocks 20. The limiting blocks 20 can support the collection mesh frame 19, so that there is an air circulation gap between the bottom of the collection mesh frame 19 and the bottom of the waste residue collection chamber. A positioning block is fixedly connected to one side wall of the waste residue collection chamber. The collection mesh frame 19 contacts the positioning block. The positioning block limits the collection mesh frame 19, so that the collection mesh frame 19 is separated from one side wall of the waste residue collection chamber.

[0032] On the side of the waste residue collection cavity far from the positioning block, there is a slag discharge port adapted to the collection mesh frame 19. The slag discharge port is sealed by a sealing plate 15. Through the setting of the slag discharge port, it is convenient for the user to clean the collection mesh frame 19, and the bottom of the slag discharge port is at the same height as the top of the limiting block 20.

[0033] On one side of the waste residue collection cavity, there is a negative pressure structure. The negative pressure structure includes a vacuum pump 4 and a vacuum tube 5. One end of the vacuum tube 5 is connected to the air inlet end of the vacuum pump 4, and the other end of the vacuum tube 5 extends into the inner cavity of the waste residue collection cavity, and the other end of the vacuum tube 5 is located on the side of the waste residue collection cavity far from the slag discharge port. Through the setting of the negative pressure structure, the work of the vacuum pump 4 can make the protective cover 1 in a negative pressure state. The outside air enters the cutting cavity through the ventilation holes, and the dusty air in the cutting cavity enters the waste residue collection cavity, avoiding the leakage of the dusty air. And the collection mesh frame 19 can filter the dusty air, and the filtered air is discharged through the air outlet end of the vacuum pump 4.

[0034] It can be seen from the above description that when the dust-proof cutting structure is in use, its internal is in a negative pressure state, avoiding the leakage of dusty air. The waste chips generated during the cutting process pass through the mesh holes on both the conveying mesh belt 2 and the bearing mesh plate 18 and can fall into the collection mesh frame 19, and the waste chips falling on the cutting raw material can be swept away by the cleaning brush 7, which is convenient for the subsequent processing of the cutting raw material.

[0035] The electrical components involved in this application are all prior arts. Those skilled in the art understand their connection methods. Through those skilled in the art, all the electrical components in this application are connected to their adapted power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. For the specific connection and control sequence, refer to the following description. The electrical components are electrically connected in the order of their sequential operations. Their detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and no further description of the electrical control will be made.

[0036] In summary, when the dust-proof cutting equipment for processing wooden base accessories is in use, the raw materials for producing wooden base accessories are placed on the conveyor belt 2. The conveyor belt 2 conveys the raw materials until they are conveyed into the cutting cavity. The first hydraulic telescopic rod 14 drives the limiting roller 17 connected thereto to move until both limiting rollers 17 are in contact with the raw materials. The combined use of the two limiting rollers 17 can adjust the position of the raw materials. After the raw materials are adjusted, the first hydraulic telescopic rod 14 stops extending. At this time, the two limiting rollers 17 clamp the raw materials to fix the position of the raw materials. The second hydraulic telescopic rod 11 retracts and extends repeatedly. The second hydraulic telescopic rod 11 drives the cutting saw blade 12 to move. The cutting saw blade 12 can cut the raw materials. During the cutting of the raw materials, the translation structure drives the cutting saw blade 12 to move, and the negative pressure structure works, making the inner cavity of the protective cover 1 in a negative pressure state to prevent dust from leaking. Moreover, the debris generated during the cutting process passes through the mesh holes on both the conveyor belt 2 and the bearing mesh plate 18 and can fall into the collection mesh frame 19 to realize the collection of waste chips, which is convenient for the unified treatment of waste chips. After the raw materials are cut, the cutting saw blade 12 resets. After the restriction of the limiting roller 17 on the raw materials is released, the conveyor belt 2 drives the raw materials to continue to move. During the movement of the raw materials, the third hydraulic telescopic rod 6 drives the cleaning brush 7 to brush the top of the raw materials to sweep away the waste residue falling on the top of the raw materials, which is convenient for the subsequent processing of the raw materials.
