Abstract

This invention relates to the field of laser engraving technology, specifically to a laser engraving device for processing the surface of decorative panels. The device includes a stage, comprising a platform, a square frame tube extending through the center of the platform, a movable translational plate below the square frame tube, a row of L-shaped suction flat tubes extending through one side of the square frame tube, a row of L-shaped blowing flat tubes extending through the other side of the square frame tube, and a power transmission component and an odor transfer component located below the translational plate. The upper surface of the translational plate in the square frame tube is the area for placing and fixing the decorative panel. A laser emitter emits laser light to engrave the decorative panel, generating an odor during the process.

This airflow directly carries away the odorous air within the square frame tube, preventing the odor generated during laser engraving from diffusing out of the square frame tube.

Description

Technical Field

[0001] This invention relates to the field of laser engraving technology, specifically to a laser engraving device for processing the surface of decorative panels. Background Technology

[0002] Laser engraving is based on CNC technology and uses laser as the processing medium. The material being processed undergoes instantaneous melting and vaporization under laser irradiation, resulting in physical deformation. This is how laser engraving achieves its processing purpose. Laser engraving uses laser technology to write text on objects. The text engraved by this technology leaves no scratches, the surface of the object remains smooth, and the text does not wear off. During the laser engraving process on the surface of decorative panels, the laser burns the surface of the decorative panel, generating and spreading an odor. If the decorative panel is made of plastic, the odor generated after laser burning will be pungent and obvious. Based on the research and development purpose of odor collection and treatment, this invention provides a laser engraving device for processing the surface of decorative panels.

The camshaft is connected to the external gear ring set on the adjusting cylinder through meshing transmission via a ring gear sleeved on it.

[0011] The air passage component includes a dispersing device, a one-way valve, an air supply concave bend pipe, a Z-shaped plate, an air section, and a return air concave bend pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The upper part of the horizontal plate in the square frame is the area for placing the fixed decorative panel. The laser emitter emits a laser to irradiate and engrave the decorative panel, which generates an odor during the process. At the same time, a row of L-shaped blowing flat tubes intermittently blow air into the square frame. During each blowing process, the corresponding L-shaped suction flat tubes simultaneously suck in air. This generates a directional airflow in the square frame, which directly carries away the odorous air in the square frame. The odor generated during the laser engraving process will not diffuse out of the square frame.

This invention uses a power component to collect and utilize the power generated during the translation of the translation plate, and then converts it into the power for airflow delivery in the air passage component. During the laser engraving process, airflow delivery is automatically synchronized to promptly collect and transfer any odors generated during laser engraving. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the technical solutions of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 11 The present invention provides a technical solution: a laser engraving device for processing the surface of decorative panels, comprising an engraving machine body 1, a laser emitter 2 for emitting laser light disposed in the engraving machine body 1, and a platform 3 for placing the panel. The platform 3 is distributed below the laser emitter 2.

[0031] refer to Figure 5Understandably, the power component 9 includes a horizontal plate 11, a horizontal plate 12, a concave folding frame 14, a moving unit 16, a vertical plate 17, and a vertical plate 18. The horizontal plate 11 and the vertical plate 18 are both fixedly attached to the translation plate 6. The vertical plate 18 is in contact with one end of the vertical plate 17 by setting a longitudinal wave surface, and the horizontal plate 11 is in contact with one end of the horizontal plate 12 by setting a transverse wave surface. The end of the concave folding frame 14 is fixed to the platform 4. The concave folding frame 14 supports two moving units 16, and the horizontal plate 12 and the vertical plate 17 are respectively fixed to the two moving units 16.

[0032] The power unit 9 also includes a drive disc 13 and an integrated shaft 15. The concave frame 14 supports the drive disc 13. The integrated shaft 15 is connected to the drive disc 13 in the middle by a helical tooth, and the two ends of the integrated shaft 15 are respectively connected to two collective driving units 16.

[0033] refer to Figure 6 It is understood that the moving unit 16 includes a unit frame 19, a driving square tube 24, a support plate 25, and a pull-back spring 26. One end of the support plate 25 is fixed to the driving square tube 24, and the other end of the support plate 25 is fixed to support the horizontal plate 12 or the vertical plate 17. One end of the unit frame 19 is fixed to the concave folding frame 14. The square plate on the unit frame 19 slides through the inner hole of the driving square tube 24. One end of the pull-back spring 26 is fixed to the driving square tube 24, and the other end is fixed to the square plate of the unit frame 19.

[0034] The integrated unit 16 also includes a ring gear 20, a unit shaft 21, a one-way bearing 22, and an outer ring gear 23. One end of the unit shaft 21 is connected to a row of teeth on the drive square tube 24 through a fixed shaft gear. The other end of the unit shaft 21 is fixedly fitted with a one-way bearing 22. An outer ring gear 23 is fixedly fitted outside the one-way bearing 22. The ring gear 20 is connected to one side of the outer ring gear 23 through a meshing transmission. The ring gear 20 is fixedly fitted on the integrated shaft 15. The integrated shaft 15 and the unit shaft 21 are respectively movably fitted into two through holes opened on the unit frame 19.

[0035] refer to Figure 7 The drive plate 13 includes an arc plate 27, a central shaft 30, a spring 31, an adjusting cylinder 32, a cross 33, a C-shaped spring 34, and a lifting plate 35. The central shaft 30 is movably sleeved in a through hole on the lifting plate 35. The spring 31 is fixedly sleeved on the outside of the central shaft 30, and the adjusting cylinder 32 is fixedly sleeved on the outside of the spring 31. The cross 33 is fixed on the lifting plate 35, and one end of the lifting plate 35 is fixed on the concave frame 14. Two arc-shaped pillars are symmetrically fixed on the cross 33 to cooperate in clamping the annular groove on the outer wall of the adjusting cylinder 32. One end of the return spring 43 is fixed on the cross 33, and the other end of the C-shaped spring 34 is locked and intercepted by the arc plate 27 fixed on the bottom surface of the adjusting cylinder 32. One end of the central shaft 30 is connected to the spiral gear on the integrated shaft 15 through a fixed gear and a helical gear meshing transmission.

[0036] The drive plate 13 also includes a cam 28 and a camshaft 29. One end of the camshaft 29 is movably sleeved in a round hole opened on the lifting plate 35, and the other end of the camshaft 29 is fixed with the cam 28. The camshaft 29 is connected to the external gear ring provided on the adjusting cylinder 32 through meshing and transmission via a ring gear sleeved on it.

[0037] refer to Figure 2 The material to be engraved is fixed at the upper surface of the translational plate 6 in the square tube 5. The translational plate 6 is clamped and positioned by a fixture of the prior art. The edge of the translational plate 6 is connected to a displacement drive mechanism of the prior art, so that the translational plate 6 can be translated in any direction. The translational plate 6 moves the material. During the process, the laser emitter 2 emits a laser, which irradiates the translated material, thereby realizing laser engraving. During the translation, the translational plate 6 drives the horizontal plate 11 and the vertical plate 18, which in turn drives the horizontal plate 12 and the vertical plate 17. The wave surface moves the horizontal plate 12 or the vertical plate 17 to move back and forth, which in turn drives the support plate 25. Then, the square tube 24 moves back and forth, which drives the unit shaft 21. During the reciprocating rotation of the unit shaft 21, the outer ring gear 23 is driven through the one-way bearing 22. The outer ring gear 23 moves intermittently and directionally, which drives the ring plate gear 20. The rotation drives the integrated shaft 15, which in turn drives the central shaft 30 to rotate, causing the spring 31 to contract and store power. The spring 31 provides power to the external adjusting cylinder 32. The adjusting cylinder 32 is stationary because the C-shaped spring 34 elastically locks the arc plate 27. When the stored power is sufficient, it will break through the interception of the C-shaped spring 34, so the spring 31 releases its power to make the adjusting cylinder 32 rotate. Then, through the camshaft 29, it drives the cam 28 to rotate continuously for many revolutions. The integrated shaft 15 continues to rotate. After the spring 31 is fully charged, it releases its power and then continues to store power. This cycle is reflected in the motion state of the cam 28. After the cam 28 rotates continuously for many revolutions, it stops for a period of time, and then rotates continuously for many revolutions again. During the continuous rotation of the cam 28, the air passage 10 times generates directional airflow in the translation plate 6 to transfer and remove the odor generated during the laser engraving process.

[0038] The air passage component 10 includes a dispersing device 36, a one-way valve 37, an air supply concave pipe 38, a Z-shaped plate 39, an air section 40, and a return air concave pipe 41. An exhaust section 40 is connected between the return air concave pipe 41 and the air supply concave pipe 38. The return air concave pipe 41 is fixedly connected to the L-shaped air intake flat cylinder 7, and the air supply concave pipe 38 is fixedly connected to the L-shaped air blowing flat cylinder 8. The dispersing device 36 supports an exhaust section 40. One end of the Z-shaped plate 39 is connected to the dispersing device 36, and the other end is actuated by a rotating cam 28. Two one-way valves 37 are provided in both the return air concave pipe 41 and the air supply concave pipe 38, and the two one-way valves 37 are distributed at both ends of an exhaust section 40.

[0039] The dispersing device 36 includes a bridge plate 42, a return spring 43, and a T-shaped plate 44. One end of the bridge plate 42 is fixed to the return air concave pipe 41, and the other end is fixed to the supply air concave pipe 38. One end of the T-shaped plate 44 slides through a plate hole opened on the bridge plate 42. One end of the return spring 43 is fixed to the bridge plate 42, and the other end is fixed to the T-shaped plate 44. The Z-shaped plate 39 is fixed to the T-shaped plate 44.

[0040] The air section 40 includes waist columns 45, an integrated body 46, a support cylinder 47, and a straight flat tube 48. The integrated body 46 is fixed on the T-moving plate 44. A row of waist columns 45 is fixed on the integrated body 46. Each waist column 45 is provided with a support cylinder 47 at both ends. One end of the support cylinder 47 is slidably inserted into the cylindrical groove opened on the waist column 45. The other end of the support cylinder 47 is fixedly connected to the straight flat tube 48. One end of one straight flat tube 48 in the air section 40 is fixedly connected to the return air concave bend pipe 41. One end of another straight flat tube 48 in the air section 40 is fixedly connected to the supply air concave bend pipe 38.

[0041] Each rotation of cam 28 actuates Z-shaped plate 39 once, causing return spring 43 to move T-shaped plate 44, which in turn resets Z-shaped plate 39. This results in one reciprocating translational motion of Z-shaped plate 39. T-shaped plate 44 drives a row of integrated bodies 46, and each integrated body 46 drives a row of waist columns 45. All waist columns 45 move axially synchronously. The reciprocating movement of waist columns 45 causes airflow movement in the support cylinders 47 at both ends. (Reference) Figure 8 All the waist columns 45 shift to the left, causing multiple airflows to converge into the straight flat tube 48, and then into the air supply concave tube 38. Guided by the two existing one-way valves 37, the airflow in the air supply concave tube 38 flows in a directional manner, and the airflow diffuses into all the L-shaped blowing flat tubes 8. Figure 2 A row of L-shaped air-blowing flat tubes 8 blows airflow into the square frame tube 5. Figure 8 The airflow in the L-shaped suction flat tube 7 is drawn into another straight flat tube 48 in the air section 40, and then replenishes the other support tube 47 that is inserted into the waist column 45. Because a waist column 45 is distributed between the two support tubes 47, the directional movement of the waist column 45 will cause air to be squeezed out of one support tube 47, while air is replenished in the other support tube 47. Figure 8 The airflow inside the L-shaped suction flat tube 7 is drawn into a row of connected straight flat tubes 48, and at the same time, the airflow in the L-shaped suction flat tube 7 is drawn into the return air concave tube 41. Figure 2 The L-shaped suction flat tube 7 absorbs the odorous air in the square tube 5, thus generating a directional airflow in the square tube 5, which is the exhaust in the L-shaped blowing flat tube 8. Subsequently, the airflow is absorbed by the L-shaped suction flat tube 7, and the airflow carries away the odor in the square tube 5. In this way, the odor generated during laser engraving is effectively transferred and discharged.

[0042] The odor is eliminated because Figure 8Both the return air concave pipe 41 and the supply air concave pipe 38 have two one-way valves 37. When the air section 40 operates, the return air concave pipe 41 and the supply air concave pipe 38 continuously breathe. One end of the return air concave pipe 41 is connected to the L-shaped intake flat tube 7 that draws in odorous air, and the other end is externally connected to an existing odorous air purification mechanism. The return air concave pipe 41 draws in odorous air during intake and exhales odorous air through the exhaust pipe, thus venting the odorous air to the air purification mechanism. A row of straight flat tubes 48 is connected to the concave air tube 41, and a row of support tubes 47 is connected to each straight flat tube 48. The reciprocating movement of the waist column 45 causes air to be drawn in and then expelled from the support tube 47. Similarly, the airflow movement in the air supply concave air tube 38 is based on the same principle. However, when the air supply concave air tube 38 exhales, the airflow is discharged through the L-shaped blowing flat tube 8. When the air supply concave air tube 38 inhales, one end of the air supply concave air tube 38 is directly exposed to the air, and outside air is drawn into the air supply concave air tube 38.
