Description

Technical Field

[0001] This application relates to the field of CNC machining, and in particular to an engraving machine with a dust collection function. Background Technology

[0002] Currently, CNC machining equipment generates material debris during the processing of materials. To promptly clean up this debris, related technologies involve installing a dust collection hood directly on the CNC engraving machine spindle, connected to an external vacuum cleaner via a suction pipe. The dust collection hood moves with the CNC engraving machine spindle, continuously sucking up the debris. However, this method increases the size of the CNC engraving machine spindle, obstructing the view of the engraving process and severely impacting the workspace in miniaturized CNC engraving machines. Furthermore, material debris scattered on the CNC engraving machine's work platform cannot be automatically cleaned up and must be manually removed by the user. Utility Model Content

[0003] This application provides an engraving machine with a dust collection function to at least solve one of the above-mentioned technical problems.

[0004] This application provides a carving machine with a dust collection function. The carving machine includes: a housing and a cover covering the housing. A dust collection base plate is installed at the bottom of the housing. The front end of the dust collection base plate is higher than the rear end of the dust collection base plate. A dust collection outlet is provided at the rear end of the housing. The dust collection outlet is connected to an external vacuum cleaner through a pipe. The front end of the dust collection base plate is the end away from the rear end of the housing, and the rear end of the dust collection base plate is the end close to the rear end of the housing.

[0005] In some embodiments, a dust collection and gathering component is provided at the rear end of the housing, which is used to collect material debris from the dust collection base plate to the dust collection outlet.

[0006] In some embodiments, a dust collection cover plate is further included to cover the rear end of the dust collection and gathering component, and the dust collection outlet is disposed on the dust collection cover plate; a guide hole is provided at a position opposite to the rear end of the dust collection base plate of the dust collection and gathering component; a guide channel is formed between the guide hole and the dust collection outlet.

[0007] In some embodiments, a frame structure is installed inside the housing, an engraving execution mechanism is installed on the crossbeam of the frame structure, and a worktable mechanism is provided on the base of the frame structure.

[0008] In some embodiments, the rear end of the dust collection base plate is provided with a U-shaped opening that avoids the base portion of the frame structure, and there are two flow guide holes, which are respectively connected and installed to the two ends of the U-shaped opening.

[0009] In some embodiments, the width of the bottom end of the frame structure is smaller than the width of the top end of the frame structure; the two ends of the U-shaped opening are installed from both sides of the bottom end of the frame structure by connecting with the two guide holes.

[0010] In some embodiments, the U-shaped opening is symmetrically provided with support members for mounting the workbench mechanism.

[0011] In some embodiments, the engraving execution mechanism includes a spindle housing, a fan disposed at the top of the spindle housing, and a tool changing structure disposed within the spindle housing; an air outlet is provided at the bottom of the spindle housing, and the air outlet faces the worktable mechanism.

[0012] In some embodiments, the air outlet includes air outlets with at least two air outlet directions.

[0013] In some embodiments, the lower end of the tool changing structure extends through the bottom wall of the spindle housing, and the air outlet is located on the side of the bottom wall of the spindle housing away from the rear end of the housing.

[0014] This application features a rearward-sloping dust collection base plate at the bottom of the engraving machine housing, and a dust collection outlet at the rear end of the housing for connecting to an external vacuum cleaner. This allows material debris generated during engraving machine operation to be collected at the dust collection outlet and then extracted by the external vacuum cleaner. This avoids the problems associated with installing dust collection hoods or other dust collection mechanisms on the engraving machine spindle, which would result in a large spindle size, reduced processing space, and obstructed view.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0018] It should also be noted that, in this document, the terms "comprising" or "including" include not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0019] like Figure 1 The diagram shows the structure of the engraving machine with dust collection function provided in this application. In this embodiment, the engraving machine includes a cover 100 and a housing 200, which together form the entire engraving machine housing. Inside the housing, a frame structure 300, an engraving execution mechanism 400, a depth track 500, and an engraving platform 600 are installed. The frame structure 300 is located at the bottom of the housing 200, and the engraving execution mechanism 400 is slidably mounted on the crossbeam of the frame structure 300 via a transverse track. The depth track 500 is located on the base of the frame structure 300, and the engraving platform 600 is slidably mounted on the depth track 500. The engraving platform 600 is used to support and mount the material to be engraved, and the cutting head carried by the engraving execution mechanism processes the material. Furthermore, a dust collection base plate 210 is also provided at the bottom of the housing 200, with the front end of the dust collection base plate 210 higher than its rear end, so that dust and material debris on the dust collection base plate can collect towards the rear end of the engraving machine. The rear end of the housing 200 is provided with a dust collection outlet, which is connected to an external vacuum cleaner through a pipe, so that the dust and material debris collected at the rear end of the engraving machine are sucked out by the suction of the vacuum cleaner.

[0020] like Figure 2 The image shown is a partial structural schematic diagram of the engraving machine with dust collection function described in this application. Figure 3 The diagram shown is a cross-sectional view of the engraving machine with dust collection function according to this application. In this embodiment, the engraving machine also has a dust collection and gathering component 220 at the rear end of the housing 200. The dust collection and gathering component 220 is used to collect material debris from the dust collection base plate 210 to the dust collection outlet 222. The front end of the dust collection and gathering component 220 is provided with a guide hole 221, which is connected to the rear end of the dust collection base plate 210. Material debris falling from the engraving platform 600 onto the dust collection base plate 210, due to the higher front end and lower rear end of the dust collection base plate 210, can collect at the guide hole 221 of the dust collection and gathering component and enter the dust collection and gathering component, and finally be sucked out by the vacuum cleaner through the dust collection outlet 222.

[0021] like Figure 4 The image shown is a top view of an embodiment of the dust collection and gathering component of this application. In this embodiment, the dust collection and gathering component 220 has a concave shape in the middle, two symmetrically arranged guide holes 221 at both ends, and a dust collection outlet 222 at the rear end. Material debris entering through the guide holes 221 passes through the channel in the dust collection and gathering component 220 and is sucked out by a vacuum cleaner from the dust collection outlet 222.

[0022] like Figure 5 The diagram shown is an assembly schematic of the frame structure and dust collection structure in this application. Figure 6 As shown Figure 5 An exploded structural diagram of the component. The dust collection structure in this embodiment includes an inclined dust collection base plate 210 and a dust collection and gathering component 220 disposed at the rear end of the dust collection base plate 210. A dust collection cover plate 230 is also fitted over the rear end of the dust collection and gathering component 220, and a dust collection outlet 222 is disposed on the dust collection cover plate 230. A guide hole 221 is provided at a position opposite to the rear end of the dust collection base plate 210 on the dust collection and gathering component 220; a guide channel is formed between the guide hole 221 and the dust collection outlet 222.

[0023] In some embodiments, a frame structure is installed inside the housing 200, an engraving execution mechanism is mounted on the crossbeam portion of the frame structure, and a worktable mechanism is provided on the base portion of the frame structure. Exemplarily, the frame structure includes a base portion 310, a crossbeam portion 320, and two symmetrically arranged support portions 330. The crossbeam portion 320 has a crossbeam groove 321 along its length for accommodating a transverse lead screw; a first transverse track mounting portion 322 is provided at the top of the crossbeam portion 320, and a second transverse track mounting portion 323 is provided at the front side of the crossbeam portion 320; a motor mounting position 324 is provided at one end of the crossbeam portion 320 for mounting a motor, which drives the transverse lead screw to rotate.

[0024] In some embodiments, a depth track mounting portion is provided on the base portion 310 for mounting a depth track, the depth track being perpendicular to the transverse track. The depth track mounting portion includes a first depth track mounting portion 311 and a second depth track mounting portion 312, with a recess 313 between the first depth track mounting portion 311 and the second depth track mounting portion 312 for accommodating a lead screw in the depth direction. The frame structure is mounted inside the engraving machine housing via the base portion 310, and the thickness of the base portion 310 along the depth direction is greater than the thickness of the two support portions 330 along the depth direction. In this embodiment, by making the thickness of the base portion along the depth direction greater than the thickness of the support portions along the depth direction, the overall thickness of the base is greater than that of the support portions located above it, improving the stability of the frame structure when mounted in the engraving machine. Furthermore, it facilitates the installation of the depth track in the depth direction.

[0025] Continue to refer to Figure 6 The length of the base portion 310 along the length direction of the crossbeam portion is less than the length of the crossbeam portion 320. The support portion 330 includes a vertical support portion 331 and an inclined connecting portion 332. The upper end of the vertical support portion 331 is connected to one end of the crossbeam portion 320, the lower end of the vertical support portion 331 is connected to the upper end of the inclined connecting portion 332, and the lower end of the inclined connecting portion 332 is connected to one side of the base portion 310.

[0026] like Figure 2 As shown, the engraving actuator 400 is mounted to the crossbeam 320 of the frame structure via a longitudinal movable component 410 and a transverse movable component 420. The engraving actuator 400 is fixedly mounted on the first side of the longitudinal movable component 410. A slide rail structure (or slide path structure) is provided on the second side of the longitudinal movable component 410 (opposite to the first side). A slide rail structure (or slide path structure) is provided on the side of the transverse movable component 420 opposite to the longitudinal movable component 410. These components cooperate with the longitudinal movable component 410 to achieve the vertical movement of the engraving actuator 400. The transverse movable component 420 includes a first extension 421 and a second extension 422 that are perpendicular to each other. The first extension 421 extends along the depth direction of the engraving machine (i.e., from the front to the rear of the engraving machine), and the second extension 422 extends along the longitudinal direction of the engraving machine. The lower surface of the first extension 421 is provided with a slide structure for mounting with the first transverse guide rail installed on the crossbeam 320; the inner surface of the second extension 422 is provided with a slide structure for mounting with the second transverse guide rail installed on the crossbeam 320.

[0027] Continue to refer to Figure 6 The dust collection base plate 210 has a U-shaped opening at its rear end to avoid the base part 310 of the frame structure. There are two flow guide holes 221, and the two flow guide holes 221 are respectively connected and installed to the two ends 211 of the U-shaped opening.

[0028] The width of the bottom end of the frame structure 300 is smaller than the width of the top end of the frame structure 300; the two ends of the U-shaped opening are installed from both sides of the bottom end of the frame structure 300 by connecting with the two guide holes 221. Support members 212 for installing the workbench mechanism are symmetrically arranged in the U-shaped opening.

[0029] like Figure 7 The image shown is a cross-sectional view of one embodiment of the engraving actuator in this application. Figure 8 The figure shown is a cross-sectional view of another embodiment of the engraving machine actuator of this application. In this embodiment, the engraving actuator 400 includes a spindle housing, a fan 401 disposed at the top of the spindle housing, and a tool changing structure (not shown) disposed within the spindle housing; an air outlet is provided at the bottom of the spindle housing, and the air outlet faces the worktable mechanism. The worktable mechanism includes at least a depth track 500 and an engraving platform 600.

[0030] In this embodiment, during actual operation, the fan 401 can both blow air to cool the tool changing structure and blow air through the outlet to the engraving platform 600 in the worktable structure, thereby blowing material debris generated during the engraving process to the bottom of the worktable, where it can be further sucked out by the dust collection mechanism. For example, with the vibration of the engraving machine during operation and the suction at the guide hole 221, the debris gradually converges at the guide hole 221 and is then sucked out.

[0031] In some embodiments, the air outlet includes air outlets with at least two airflow directions. For example... Figure 7 The air outlet 402 shown (arrows in the diagram indicate airflow direction) is angled towards the interior of the engraving machine. For example... Figure 8 The air outlet shown has an airflow direction (arrows in the diagram indicate airflow direction) that is vertically downwards. In some embodiments, a third air outlet may be provided, and the airflow direction of the third air outlet may be the same as... Figure 7 The air outlet shown has the same air outlet direction as or is the same as the air outlet direction. Figure 8 The air outlets shown all point in the same direction as the air outlets, or the air outlet of the third outlet points in the same direction as the air outlet. Figure 7 and Figure 8 The numbers and directions of the air outlets are all different. It should be noted that the number and direction of the air outlets mentioned above are just examples, and this application does not limit them.

[0032] In some embodiments, the lower end of the tool changing structure protrudes through the bottom wall of the spindle housing, and the air outlet is located on the side of the bottom wall of the spindle housing away from the rear end of the housing. In this embodiment, by placing the air outlet on the outside of the bottom wall of the spindle housing, the material debris generated during the engraving process can be blown into the interior of the engraving machine housing to the greatest extent, making it easier for the dust collection mechanism to suck out the material debris.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
