[0018] Beneficial effects of the present invention:

[0019] 1. In the initial state, the flip plate is in a vertical state (perpendicular to the bottom plate), so that it can block one side of the electric guide rail located below, avoiding the metal debris generated during the processing of the workpiece from being ejected into the electric guide rail and the installation guide rail located below, thereby affecting the opening and closing of the main sliding door panel and the auxiliary sliding door panel. When the engraving machine has finished processing and cleaning the workpiece, the electric guide rail drives the main sliding door panel to move and open. In the process, the main sliding door panel drives the rotating shaft to rotate the installation sleeve and the flip plate (rotate in the direction away from the main sliding door panel) with the cooperation of the linkage assembly, thereby avoiding the flip plate affecting the picking of the workpiece.

[0020] 2. When the workpiece is processed and cleaned, the electric guide rail drives the main sliding door panel to move horizontally and open. During the movement of the main sliding door panel, the inclined convex strip is driven to move together. When the inclined convex strip contacts the interference wheel, the lifting plate will be prompted to move upward with the rack through the interference wheel. During the upward movement of the rack, the driving gear, rotating shaft, mounting sleeve and flip plate will rotate accordingly. At this time, the torsion springs at both ends of the mounting sleeve produce elastic deformation to store elastic potential energy. When the processed workpiece is taken away and the new workpiece to be processed is placed, the electric guide rail drives the main sliding door panel to move horizontally and close. During this process, the main sliding door panel moves away from the interference wheel with the inclined convex strip. At this time, the elastic potential energy stored in the torsion spring is gradually released, prompting the mounting sleeve and the flip plate to flip to a vertical state again, which is easy to use.

[0021] 3. When the debris and cutting fluid fall onto the filter through the lower slot under the action of airflow and gravity, the debris is intercepted by the filter, and the cutting fluid continues to drip downward through the filter, and drips into the waste liquid collection box through the inclined elastic plate. Since the air nozzle blows downward, when the airflow acts on the filter, it causes the filter to vibrate, avoiding local accumulation of metal debris on the filter. When the airflow acts on the inclined elastic plate, it causes the inclined elastic plate to shake, accelerating the sliding of the cutting fluid. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Reference Figure 6 and Figure 7 A mounting slider is slidably arranged in each mounting rail 4, and the auxiliary sliding door panel 5 is fixed between the two mounting sliders. An electric slider is slidably arranged in each electric rail 6, and the main sliding door panel 7 is fixed between the two electric sliders. This part of the structure is the existing technology.

[0034] Reference Figure 2 and Figure 3 In the initial state, the flip plate 11 is in a vertical state (perpendicular to the bottom plate 2), so that it can block one side of the electric guide rail 6 located below, avoiding the metal debris generated during the processing of the workpiece from being ejected into the electric guide rail 6 and the mounting guide rail 4 located below, thereby affecting the opening and closing of the main sliding door panel 7 and the auxiliary sliding door panel 5, and when the engraving machine has completed the processing and cleaning of the workpiece, the electric guide rail 6 drives the main sliding door panel 7 to move and open. In the process, the main sliding door panel 7, with the cooperation of the linkage assembly, drives the rotating shaft 9 to drive the mounting sleeve 10 and the flip plate 11 to rotate (rotate in the direction away from the main sliding door panel 7), thereby avoiding the flip plate 11 affecting the picking of the workpiece.

[0035] Reference Figure 4 One end of the rotating shaft 9 away from the main sliding door panel 7 rotates through the mounting seat 8 and is fixedly sleeved with a gear 13.

[0036] Reference Figure 3 , Figure 4 and Figure 5The linkage assembly includes a U-shaped limit seat 14 fixed to the upper end surface of the bottom plate 2, a lifting plate 15 is set in the U-shaped limit seat 14 for lifting and sliding, a rack 16 is fixed to one side of the lifting plate 15, the rack 16 is meshed and connected with the gear 13, and a contact wheel 17 is rotatably set on the other side of the lifting plate 15, and an inclined convex strip 18 used to cooperate with the contact wheel 17 is fixed on the side wall of the main sliding door panel 7.

[0037] Reference Figure 3 , Figure 4 and Figure 5 When the workpiece is processed and cleaned, the electric guide rail 6 drives the main sliding door panel 7 to move horizontally and open. During the movement of the main sliding door panel 7, the inclined convex strip 18 is driven to move together.

During the upward movement of the rack 16, the driving gear 13, the rotating shaft 9, the mounting sleeve 10 and the flip plate 11 rotate accordingly. At this time, the torsion springs at both ends of the mounting sleeve 10 produce elastic deformation to store elastic potential energy.

During this process, the main sliding door panel 7 moves away from the contact wheel 17 with the inclined convex strip 18. At this time, the elastic potential energy stored in the torsion spring is gradually released, prompting the mounting sleeve 10 and the flip plate 11 to flip to a vertical state again, which is convenient to use.

[0038] Reference Figure 2 A movable seat 35 is movably arranged in the protective cover 3, and a tool and a cutting fluid injection assembly are fixed on the lower end surface of the movable seat 35. This part of the structure is the existing technology.

A mounting plate 21 is movably arranged above the bottom plate 2, and a ventilation pipe 22 is fixed on the lower end surface of the mounting plate 21. A plurality of blowing nozzles 23 are connected to the lower end surface of the ventilation pipe 22, and a baffle 24 is fixed on the upper end surface of the bottom plate 2. An air supply component used in conjunction with the ventilation pipe 22 is arranged in the protective cover 3, and a translation component used in conjunction with the mounting plate 21 is arranged in the protective cover 3. The upper end surface of the base 1 is open, and a collecting component is arranged in the base 1.

[0040] Reference Figure 2 and Figure 3When in use, the workpiece to be processed is fixed on the placement tool 19, and the workpiece is processed by the cooperation of the tool and the cutting fluid injection assembly. When the workpiece is processed, the tool and the cutting fluid injection assembly return to the initial position (away from the workpiece), and then the translation assembly drives the mounting plate 21 and the vent pipe 22 to move. During the movement of the vent pipe 22, under the action of the air supply assembly, air is blown downward through each blowing nozzle 23, thereby blowing the processing debris and chip fluid on the workpiece, the placement tool 19 and the base plate 2 into the lower through groove 20, and the metal debris and the used cutting fluid are collected by the collecting assembly.

[0041] The air supply assembly includes an air supply pump fixed to the upper end surface of the bottom plate 2, a telescopic hose is provided between the air outlet of the air supply pump and the vent pipe 22, and a slot is provided on the protective cover 3 for use with the air inlet of the air supply pump.

[0042] When the air supply pump is working, an air flow is generated, which is guided into the vent pipe 22 through the telescopic hose and then discharged through each air blowing nozzle 23 to perform a debris cleaning operation.

[0043] Reference Figure 2 The translation assembly includes a connecting seat 25 fixed to one side of the mounting plate 21, a connecting seat 26 is fixed to the upper end surface of the connecting seat 25, two guide columns 27 are symmetrically fixed on the inner wall of the protective cover 3, each guide column 27 movably penetrates the connecting seat 26, a reciprocating screw 28 is rotatably arranged on the inner wall of the protective cover 3, the reciprocating screw 28 is threadedly penetrated through the connecting seat 25, and a motor used in conjunction with the reciprocating screw 28 is fixed on the outer wall of the protective cover 3.

[0044] Reference Figure 2 When the motor is working, the reciprocating screw rod 28 will drive the connecting seat 1 25 to move, and the connecting seat 1 25 will move with the connecting seat 2 26, the mounting plate 21 and the vent pipe 22 to cooperate in the debris cleaning operation. The guide column 27 is set to ensure the stability of the connecting seat 2 26 and the connecting seat 1 25 during the movement.

[0045] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 The collecting component includes an installation frame 29 slidably arranged in the base 1, a filter screen 30 is fixed on the inner wall of the installation frame 29, a pull-out groove 1 for cooperating with the installation frame 29 is opened on one side of the base 1, a handle 31 is fixed on one side of the installation frame 29, a waste liquid collection box 32 is fixed on the inner bottom of the base 1, the upper end surface of the waste liquid collection box 32 is open, and a pull-out groove 2 for cooperating with the waste liquid collection box 32 is opened on one side of the base 1.

[0046] Reference Figure 8Two inclined elastic plates 33 are symmetrically fixed to the lower end surface of the mounting frame 29 , and blocking bars 34 are fixed to both sides of the upper end surface of each inclined elastic plate 33 , and a second notch is opened on the side wall of the base 1 .

[0047] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 When the debris and cutting fluid fall onto the filter screen 30 through the lower through groove 20 under the action of airflow and gravity, the debris is intercepted by the filter screen 30, and the cutting fluid continues to drip downward through the filter screen 30, and drips into the waste liquid collection box 32 through the inclined elastic plate 33. Since the air blowing nozzle 23 blows downward, when the airflow acts on the filter screen 30, it causes the filter screen 30 to vibrate, thereby preventing metal debris from locally accumulating on the filter screen 30. When the airflow acts on the inclined elastic plate 33, it causes the inclined elastic plate 33 to shake, thereby accelerating the sliding of the cutting fluid.

[0048] Reference Figure 6 and Figure 7 Two linkage slide grooves 36 are symmetrically provided on the inner wall of the auxiliary sliding door panel 5 , and a linkage slider is slidably arranged in each linkage slide groove 36 , and the linkage slider is fixedly connected to the side wall of the main sliding door panel 7 .

[0049] By cooperating with the linkage slide groove 36 and the linkage slider, the main sliding door panel 7 can drive the auxiliary sliding door panel 5 to move, which is an existing conventional technical means.

[0050] When the present invention is used, refer to Figure 2 and Figure 3 In the initial state, the flip plate 11 is in a vertical state (perpendicular to the bottom plate 2), so that it can block one side of the electric guide rail 6 located below, to prevent the metal debris generated during the workpiece processing from being ejected into the electric guide rail 6 and the mounting guide rail 4 located below, thereby affecting the opening and closing of the main sliding door panel 7 and the auxiliary sliding door panel 5, and when the engraving machine has finished processing and cleaning the workpiece, the electric guide rail 6 drives the main sliding door panel 7 to move and open, and the main sliding door panel 7 drives the rotating shaft 9 to drive the mounting sleeve 10 and the flip plate 11 to rotate (rotate in the direction away from the main sliding door panel 7) under the cooperation of the linkage assembly, thereby preventing the flip plate 11 from affecting the picking up of the workpiece;

[0051] Reference Figure 2 and Figure 3The workpiece to be processed is fixed on the placement fixture 19, and the workpiece is processed by the cooperation of the tool and the cutting fluid injection assembly. When the workpiece is processed, the tool and the cutting fluid injection assembly return to the initial position (a position away from the workpiece), and then the translation assembly drives the mounting plate 21 and the vent pipe 22 to move. During the movement of the vent pipe 22, under the action of the air supply assembly, air is blown downward through each blowing nozzle 23, so that the processing debris and chip liquid on the workpiece, the placement fixture 19 and the bottom plate 2 are blown into the lower through groove 20, and the metal debris and the used cutting fluid are collected by the collecting assembly;

[0052] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 When the debris and cutting fluid fall onto the filter screen 30 through the lower through groove 20 under the action of airflow and gravity, the debris is intercepted by the filter screen 30, and the cutting fluid continues to drip downward through the filter screen 30, and drips into the waste liquid collection box 32 through the inclined elastic plate 33. Since the air blowing nozzle 23 blows air downward, when the airflow acts on the filter screen 30, it causes the filter screen 30 to vibrate, thereby preventing metal debris from being locally accumulated on the filter screen 30. When the airflow acts on the inclined elastic plate 33, it causes the inclined elastic plate 33 to shake, thereby accelerating the sliding of the cutting fluid.

[0053] Reference Figure 3 , Figure 4 and Figure 5 When the workpiece is processed and cleaned, the electric guide rail 6 drives the main sliding door panel 7 to move horizontally and open. During the movement of the main sliding door panel 7, the inclined convex strip 18 is driven to move together. When the inclined convex strip 18 contacts the contact wheel 17, the contact wheel 17 will prompt the lifting plate 15 to move upward with the rack 16. During the upward movement of the rack 16, the driving gear 13, the rotating shaft 9, the mounting sleeve 10 and the flip plate 11 rotate accordingly. At this time, the torsion springs at both ends of the mounting sleeve 10 produce elastic deformation to store elastic potential energy. When the processed workpiece is taken out and the new workpiece to be processed is placed, the electric guide rail 6 drives the main sliding door panel 7 to move horizontally and close. During this process, the main sliding door panel 7 moves away from the contact wheel 17 with the inclined convex strip 18. At this time, the elastic potential energy stored in the torsion spring is gradually released, prompting the mounting sleeve 10 and the flip plate 11 to flip to a vertical state again, which is convenient to use.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
