A precise carving machine with dust suction mechanism

Abstract

This utility model relates to the field of engraving machine technology, specifically to an engraving machine equipped with a dust collection mechanism. It includes an engraving machine body, which comprises a hanger and an engraving head. A corrugated hose is fixedly connected to one side of the engraving head, and a dust collection box is fixedly connected to one end of the hanger. A connecting pipe is fixedly connected to the top of the dust collection box. After the machine finishes engraving a batch of materials, the end cap can be unscrewed, and air can be blown by a second fan. When the second fan rotates, it drives the abutment rod to rotate. Through the setting of the fixing ring, the fixing ring is pushed up and reset, simultaneously driving the spring to compress and rebound, causing one end of the push rod to strike the filter screen. Combined with the air blowing from the second fan, this vibrates and blows back the debris on the filter screen surface. The inclined setting of the filter screen guides some of the debris to be collected in the collection trough for temporary storage, preventing filter screen blockage and reducing the frequency of opening the dust collection box to clean the filter screen.

Description

Technical Field

[0001] This utility model relates to the field of engraving machine technology, specifically to an engraving machine equipped with a dust collection mechanism. Background Technology

[0002] In the field of precision machining, CNC engraving machines are widely used as core equipment for engraving high-precision parts such as jewelry, molds, and electronic components. However, the high-speed friction between the cutting tool and the workpiece during the processing generates a large amount of debris. If it cannot be effectively collected, it will have multiple negative impacts on the production environment and equipment operation. Dust diffusion will pollute the air in the workshop, and long-term inhalation can easily cause respiratory diseases in operators. Usually, a fixed dust collection hood is set up near the engraving head of the CNC engraving machine, and a fan is used to draw the dust-laden gas to the dust collection box. After being filtered by the filter screen, clean gas is discharged.

[0003] During the processing, existing CNC engraving machines use filters for dust removal. These filters are usually fixed inside the dust collection box with bolts or clips. Cleaning requires completely disassembling the dust collection box and opening multiple locks, which is cumbersome. In continuous production scenarios, frequent machine shutdowns for maintenance can seriously affect production efficiency.

[0004] Therefore, a precision engraving machine with a dust collection mechanism is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a CNC engraving machine equipped with a dust collection mechanism. This solves the problem that existing CNC engraving machines rely on filters for dust removal. These filters are often fixed inside the dust collection box with bolts or clips, requiring complete disassembly of the dust collection box and opening multiple locks for cleaning. This cumbersome operation, especially in continuous production scenarios, leads to frequent downtime for maintenance, which severely impacts production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a CNC engraving machine body, which comprises a hanger and an engraving head. A corrugated hose is fixedly connected to one side of the engraving head. A dust collection box is fixedly connected to one end of the hanger. A connecting pipe is fixedly connected to the top of the dust collection box. A first fixed pipe is fixedly connected to one side of the dust collection box. A first fan is fixedly connected to the inner side of the first fixed pipe. A bracket is fixedly connected to the inner side of the dust collection box. A mesh frame is inserted into the top of the bracket. A filter screen is welded to the inner side of the mesh frame. Two filters are provided, and collection grooves are welded to the ends of the two filters. A door panel is fixedly connected to the front of the dust collection box, and a limit groove is provided on one side of the door panel.

[0007] Preferably, the filter screen is inclined, and one end of the corrugated hose is fixedly connected to the end of the connecting pipe.

[0008] Preferably, the bottom of the space frame is integrally formed with an L-shaped plate, one end of which is inserted into the inner side of the limiting groove.

[0009] Preferably, the bottom of the dust collection box is fixedly connected to a second fixed pipe, one end of the second fixed pipe is threadedly connected to an end cap, a second fan is fixedly connected to the inner side of the second fixed pipe, an abutment rod is fixedly connected to the outer side of one end of the output shaft of the second fan, a ball is rotatably connected to one end of the abutment rod, a guide block is integrally formed on the inner cavity sidewall of the dust collection box, a top rod is slidably connected to the top of the guide block, a spring is sleeved on the outer side of the top rod, a fixing ring is fixedly connected to the bottom of the top rod, and a corrugated groove is formed at the bottom of the fixing ring.

[0010] Preferably, there are two abutment rods, and the ball bearings are fitted into the corrugated groove at the bottom of the retaining ring.

[0011] Preferably, one end of the top rod is glued and fixed with a rubber pad, and two top rods are provided.

[0012] Preferably, one end of the spring abuts against the bottom of the guide block, and the other end of the spring abuts against the outside of the top rod.

[0013] Compared with the prior art, this utility model provides a precision engraving machine with a dust collection mechanism, which has the following beneficial effects: The first fan extracts the air from inside the dust collection box, and then the debris generated during the grinding of the engraving machine head is drawn into the dust collection box through the corrugated hose. The debris is then filtered through the filter screen, thus achieving the dust collection effect. The mesh frame is positioned by a plug-in bracket. When the door panel is installed on the dust collection box with screws, the L-shaped plate at the bottom of the mesh frame is inserted into the inner side of the limiting groove. The mesh frame is indirectly fixed by the installation and fixation of the door panel, which facilitates the subsequent assembly and disassembly of the mesh frame without the need to disassemble the mesh frame separately, making the operation more convenient.

[0014] After the equipment finishes engraving a batch of materials, the end cap can be unscrewed, and air can be blown through the second fan. When the second fan rotates, it drives the abutment rod to rotate. Through the setting of the fixing ring, the fixing ring is pushed up and reset, and the spring is compressed and rebounded at the same time, so that one end of the top rod strikes the filter screen. With the air blown by the second fan, the debris on the surface of the filter screen is vibrated and blown back. Through the inclined setting of the filter screen, some debris is collected in the collection trough for temporary storage, preventing the filter screen from clogging and reducing the frequency of opening the dust collection box to clean the filter screen.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Please see Figures 1-5 This embodiment of a precision engraving machine with a dust collection mechanism includes a precision engraving machine body 1, which includes a hanger 2 and a carving head 3. A corrugated hose 4 is fixedly connected to one side of the carving head 3. A dust collection box 5 is fixedly connected to one end of the hanger 2. A connecting pipe 6 is fixedly connected to the top of the dust collection box 5. A first fixed pipe 7 is fixedly connected to one side of the dust collection box 5. A first fan 8 is fixedly connected to the inner side of the first fixed pipe 7. A bracket 9 is fixedly connected to the inner side of the dust collection box 5. A mesh frame 10 is inserted into the top of the bracket 9. A filter screen 11 is welded to the inner side of the mesh frame 10. There are two filters 11. A collection groove 12 is welded to the ends of the two filters 11. A door panel 13 is fixedly connected to the front of the dust collection box 5. A limit groove 14 is opened on one side of the door panel 13. A sealing gasket is provided at the connection between the door panel 13 and the dust collection box 5.

[0019] The first fan 8 extracts the gas from inside the dust collection box 5, thereby drawing the debris generated during the grinding of the engraving machine head 3 into the dust collection box 5 through the corrugated hose 4. The debris is then filtered through the filter screen 11, thus achieving the dust collection effect. The mesh frame 10 is positioned by the plug-in bracket 9. When the door panel 13 is installed on the dust collection box 5 with screws, the L-shaped plate at the bottom of the mesh frame 10 is inserted into the inner side of the limiting groove 14. The mesh frame 10 is indirectly fixed by the installation and fixation of the door panel 13, which facilitates the subsequent disassembly and assembly of the mesh frame 10 without the need to disassemble the mesh frame 10 separately, making the operation more convenient.

[0020] Furthermore, the filter screen 11 is inclined, and one end of the corrugated hose 4 is fixedly connected to the end of the connecting pipe 6.

[0021] Furthermore, the bottom of the space frame 10 is integrally formed with an L-shaped plate, one end of which is inserted into the inner side of the limiting groove 14.

[0022] Furthermore, a second fixed pipe 15 is fixedly connected to the bottom of the dust collection box 5. One end of the second fixed pipe 15 is threadedly connected to an end cap 16. A second fan 17 is fixedly connected to the inner side of the second fixed pipe 15. An abutment rod 18 is fixedly connected to the outer side of one end of the output shaft of the second fan 17. A ball bearing 19 is rotatably connected to one end of the abutment rod 18. A guide block 20 is integrally formed on the inner cavity side wall of the dust collection box 5. A top rod 21 is slidably connected to the top of the guide block 20. A spring 22 is sleeved on the outer side of the top rod 21. A fixing ring 23 is fixedly connected to the bottom of the top rod 21. A corrugated groove 24 is opened at the bottom of the fixing ring 23.

[0023] After the equipment finishes engraving a batch of materials, the end cap 16 can be unscrewed, and air can be blown by the second fan 17. When the second fan 17 rotates, it drives the abutment rod 18 to rotate. Through the setting of the fixing ring 23, the fixing ring 23 is pushed up and reset, and the spring 22 is compressed and rebounded at the same time, so that one end of the top rod 21 strikes the filter screen 11. With the air blown by the second fan 17, the debris on the surface of the filter screen 11 is vibrated and blown back. Through the inclined setting of the filter screen 11, some debris is collected in the collection groove 12 for temporary storage, preventing the filter screen 11 from clogging and reducing the frequency of opening the dust collection box 5 to clean the filter screen 11.

[0024] Furthermore, there are two abutment rods 18, and the ball bearing 19 fits into the corrugated groove 24 at the bottom of the retaining ring 23.

[0025] Furthermore, a rubber pad is glued to one end of the top rod 21, and there are two top rods 21.

[0026] Furthermore, one end of the spring 22 abuts against the bottom of the guide block 20, and the other end of the spring 22 abuts against the outside of the push rod 21.

[0027] The working principle of the above embodiment is as follows: the first fan 8 extracts the gas inside the dust collection box 5, thereby drawing the debris generated during the grinding of the engraving machine head 3 into the dust collection box 5 through the corrugated hose 4, and filtering it through the filter screen 11, thus achieving the dust collection effect. The mesh frame 10 is positioned by the plug-in bracket 9. When the door panel 13 is installed on the dust collection box 5 with screws, the L-shaped plate at the bottom of the mesh frame 10 is inserted into the inner side of the limiting groove 14. The mesh frame 10 is indirectly fixed by the installation and fixation of the door panel 13, which facilitates the subsequent disassembly and assembly of the mesh frame 10 without the need to disassemble the mesh frame 10 separately, making the operation more convenient. When the equipment is... After a batch of materials is engraved, the end cap 16 can be unscrewed, and air can be blown through the second fan 17. When the second fan 17 rotates, it drives the abutment rod 18 to rotate. Through the setting of the fixing ring 23, the fixing ring 23 is pushed up and reset, which simultaneously drives the spring 22 to compress and rebound, causing one end of the top rod 21 to strike the filter screen 11. Combined with the air blowing from the second fan 17, this vibrates and blows back the debris on the surface of the filter screen 11. Through the inclined setting of the filter screen 11, some debris is collected in the collection groove 12 for temporary storage, preventing the filter screen 11 from clogging and reducing the frequency of opening the dust collection box 5 to clean the filter screen 11. The main body 1 of the engraving machine can be an FMDK-2030 engraving machine. The structure and principle of this model are existing technologies and will not be described in detail here.
