Abstract
Description
Technical Field
[0001] This invention relates to the field of automatic processing equipment technology, and in particular to a waste removal device for a precision engraving machine. Background Technology
[0002] As a general-purpose automated machining equipment, the CNC engraving machine can cut metal workpieces according to a set program, and can process workpieces with high precision requirements and complex shapes. During workpiece processing, the CNC engraving machine generates chips that need to be removed. To improve processing efficiency, these chips need to be cleaned in real time during processing. Currently, the mainstream waste removal methods include using air nozzles to blow away the chips or using cutting fluid to remove chips from the workpiece during processing. However, using air nozzles can easily lead to uncontrollable chip flight, affecting the processed workpiece, and it's difficult to remove the chips from the machining table in a timely manner. While using cutting fluid can effectively prevent chips from flying around, the cutting fluid mixes with the chips and accumulates in the edges and crevices of the machining table, making chip removal inconvenient. Summary of the Invention
[0003] The purpose of this invention is to provide a waste removal device for a CNC engraving machine, specifically a waste removal device for a CNC engraving machine that can effectively clean up processing debris and remove the debris from the processing table in a timely manner.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a waste removal device for a precision engraving machine, comprising a processing platform, an inclined waste removal table surface arranged around the processing platform, a waste removal gap arranged around the inclined waste removal table surface, and a collection chamber arranged below the waste removal gap; a waste removal air nozzle is arranged above the processing platform, the waste removal air nozzle being used to blow debris from the workpiece on the processing platform toward the inclined waste removal table surface, a cleaning fluid nozzle is arranged above the inclined waste removal table surface, the cleaning fluid nozzle being used to flush debris on the inclined waste removal table surface toward the waste removal gap; a filtration and recovery device is arranged inside the collection chamber for filtering the cleaning fluid in the collection chamber and supplying it to the cleaning fluid nozzle.
[0005] Specifically, the inclined waste discharge platform is provided with several diversion waste discharge channels, which are formed by several diversion protrusions on the inclined waste discharge platform.
[0006] Specifically, several diversion protrusions are distributed in multiple rows, and the diversion protrusions in adjacent rows are staggered to form a diamond-shaped grid-like waste discharge channel on the inclined waste discharge platform.
[0007] Specifically, the diversion protrusions and the inclined waste discharge platform are connected by a smooth arc.
[0008] Specifically, the collection chamber is funnel-shaped, with the top opening aligned with the waste discharge gap around the inclined waste discharge platform, and the filtration and recycling device is located at the bottom of the collection chamber.
[0009] Specifically, the filtration recovery device is located at the bottom of the collection chamber. The filtration recovery device includes an annular baffle, which is sealed to the bottom of the collection chamber. An outlet is provided at the center of the annular baffle at the bottom of the collection chamber.
[0010] Specifically, the bottom of the collection chamber has an openable and closable chip discharge port on the outside of the annular baffle.
[0011] Specifically, the top of the annular baffle is provided with several drainage notches, and the outer edge of the drainage notches is also provided with material-blocking protrusions.
[0012] The beneficial effects of this invention are as follows: by sequentially setting an inclined waste discharge platform and a waste discharge gap on the outer edge of the processing platform, and cooperating with air nozzles and cleaning fluid nozzles, the processing debris is flushed from the processing platform through the inclined waste discharge platform to the waste discharge gap, where it is collected in the collection bin. The cleaning fluid can be filtered out and repeatedly supplied to the cleaning fluid nozzles, which can effectively clean the debris on the processing platform and remove it in a timely manner, avoiding the problem of debris remaining on the platform or requiring frequent manual cleaning, which affects the processing efficiency.

Detailed Implementation
[0015] Example 1, referring to Figure 1-5A waste removal device for a CNC engraving machine includes a processing platform 1, an inclined waste removal table 2 around the processing platform 1, a waste removal gap 3 around the inclined waste removal table 2, and a collection chamber 4 below the waste removal gap 3; a waste removal air nozzle 5 is installed above the processing platform 1 to blow debris from the workpiece on the processing platform 1 toward the inclined waste removal table 2; a cleaning fluid nozzle 6 is installed above the inclined waste removal table 2 to flush debris on the inclined waste removal table 2 toward the waste removal gap 3; and a filtration and recovery device is installed in the collection chamber 4 to filter the cleaning fluid in the collection chamber 4 and supply it to the cleaning fluid nozzle 5.
[0016] In this embodiment, a fixed base can be provided on the processing platform 1. The fixed base is used to clamp and fix the workpiece. This component is not an innovation of the present invention, so it is not shown in the accompanying drawings. Cleaning air nozzles 5 are provided around the processing platform 1 to blow processing debris toward the inclined waste discharge table 2. The cleaning air nozzles 5 can adopt the conventional air jet cleaning structure (some engraving machines come with an air jet cleaning structure). It can blow away debris while the engraving machine is processing the workpiece. It can be set on the top of the engraving machine or directly set on the cutter head drive mechanism of the engraving machine to move with the cutter head. When the engraving machine itself has an air jet cleaning structure that cannot meet the air blowing cleaning needs, an air jet device can be added around the fixed base above the processing platform near the fixed base of the workpiece. The height of the air jet device generally does not exceed the height of the fixed base to avoid collision with the workpiece. The cleaning fluid nozzle 6 sprays cleaning fluid to flush debris out of the inclined waste discharge platform 2, allowing the debris and cleaning fluid to flow down through the waste discharge gap 3. This effectively removes the debris from the engraving machine's processing platform 1, ensuring the entire process can be completed without stopping the engraving machine and maximizing its processing efficiency. After flowing down through the waste discharge gap 3, the debris and cleaning fluid enter the collection chamber 4. The filtration and recovery device in the collection chamber 4 filters out the debris and reuses the filtered cleaning fluid by supplying it back to the cleaning fluid nozzle, preventing waste of the cleaning fluid.
[0017] Specifically, the inclined waste discharge platform 2 is provided with several diversion waste discharge channels 21, which are formed by several diversion protrusions 22 on the inclined waste discharge platform 2. These diversion protrusions 22 are arranged in multiple rows, with adjacent rows staggered to form a diamond-shaped grid of waste discharge channels 21 on the inclined waste discharge platform 2. The diversion protrusions 22 are smoothly connected to the inclined waste discharge platform 2 using an arc. By setting the diversion protrusions 22 on the inclined waste discharge platform 2 to form the diversion waste discharge channels 21, the flow rate of the cleaning fluid on the inclined waste discharge platform 2 can be increased, improving the cleaning effect on debris. Simultaneously, the smooth arc connection between the diversion protrusions 22 and the inclined waste discharge platform 2 prevents debris from getting stuck at the connection point. Specifically, the diversion protrusions 22 can be integrally connected to the inclined waste discharge platform 2 to ensure sufficient smoothness.
[0018] Specifically, the collection chamber 4 is funnel-shaped, with its top opening aligned with the waste discharge gap 3 around the inclined waste discharge platform 2. A filtration and recovery device is located at the bottom of the collection chamber 4. This device includes an annular baffle 7, which is sealed to the bottom of the collection chamber 4. An outlet 41 is located at the center of the annular baffle 7 at the bottom of the collection chamber 4. The mixture of debris and cleaning fluid flows into the collection chamber 4 through the waste discharge gap 3 and then flows through the side wall to the bottom. The annular baffle 7 at the bottom of the collection chamber 4 separates the debris, which settles at the bottom edge under gravity. When the cleaning fluid accumulates above the height of the annular baffle 7, it flows through the baffle 7 and out through the outlet 41 at the center of the bottom of the collection chamber 4. A liquid pump can then pump the cleaning fluid to the supply point of the cleaning fluid nozzle 6 for recycling. The entire filtration and recovery process does not require a filter screen. The filter components are integrated, eliminating the need for replacement. Furthermore, to control the flow rate of the cleaning fluid passing through the top of the annular baffle 7 and prevent the fluid from carrying away small amounts of debris due to excessive flow, the top of the annular baffle 7 is equipped with several drainage notches 71. The outer edges of the drainage notches 71 are also equipped with baffle protrusions 72. The drainage notches 71 effectively control the flow rate of the cleaning fluid, and the baffle protrusions 72 on the outer edges of the drainage notches 71 also act as debris shields, further preventing small amounts of fine particles from passing through and optimizing the filtration effect. The debris settled at the bottom of the collection chamber 4 only needs to be cleaned periodically. Furthermore, the bottom of the collection chamber 4 has an openable and closable debris discharge port 42 located on the outer side of the annular baffle 7, through which debris settled at the bottom of the collection chamber 4 can be discharged.
[0019] Of course, the above are only preferred embodiments of the present invention and are not intended to limit the scope of application of the present invention. Therefore, any equivalent changes made to the principle of the present invention should be included within the protection scope of the present invention.
