An additional set of filter boxes needs to be added on one side of the chip removal device, and the metal chips in the chip removal device are manually fished into the filter boxes for filtration and recovery, which is time-consuming and laborious; 2. If the existing spiral chip removal machine is used, it needs to be installed on one side of the machine tool, which increases the overall floor area of the machine tool. It is not beautiful and is not conducive to the use of the client. Those skilled in the art urgently need to solve the above technical problems. Content of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0030] As Figure 1-2 shown, a chip removal structure of a numerically controlled engraving machine provided by the present utility model includes a chip removal machine 1, a chip collection trolley 2 and a cutting fluid filtration and recycling device 3;

[0031] The cutting fluid filtering and recycling device 3 is installed at the bottom on one side of the machine tool body 4, and it includes a cutting fluid collection tank 31, a cutting chip filter tank 32 arranged in the cutting fluid collection tank 31, and a cutting fluid recycling tank 33. The cutting chip filter tank 32 is detachably installed in the cutting fluid collection tank 31;

[0032] The chip conveyor 1, as Figure 3 shown, is installed in the cutting fluid collection tank 31, and it includes a chip guide groove 11, a chip discharge cylinder 12 connected to one end of the chip guide groove 11, and a screw rod 13. The chip guide groove 11 penetrates through the cutting chip filter tank 32 and is connected to it to form a collection cavity for cutting chips, which can store the cutting chips dropped during the machining of the engraving machine. The screw rod 13 is located on the chip guide groove 11, and the screw rod 13 is connected with a driving part 14. The driving part 14 is set as a motor, and the screw rod 13 is directly or indirectly connected to the output shaft of the motor through a coupling;

[0033] When the driving end of the driving part 14 drives the screw rod 13 to rotate, the screw rod 13 can send the cutting chips on the chip guide groove 11 to one end of the chip discharge cylinder 12;

[0034] Also as Figure 1 shown, since the machine tool body 4 is provided with an electrical cabinet on the same side of the cutting fluid collection tank 31, and the electrical cabinet needs to leave a certain maintenance space. To further reduce the floor area of the machine tool, the chip discharge cylinder 12 is deflected 90 degrees upward along the axial direction of the chip guide groove 11, so that the discharge port of the chip discharge cylinder 12 faces one side of the machine tool body 4 and is on the same side as the electrical cabinet, reducing the space at the rear of the machine tool.

[0035] On the basis of the above embodiment, as Figure 4 shown, the cutting chip filter tank 32 includes a left chip baffle 321 and a right chip baffle 322 which are symmetrically arranged. The left chip baffle 321 and the right chip baffle 322 are respectively placed on both sides of the chip guide groove 11 and are connected to the cutting fluid collection tank 31 through a plurality of screws or bolts. A number of coarse filter holes are provided on the left chip baffle 321 and the right chip baffle 322.

[0036] During the installation process, a bearing part for the cutting chip filter tank 32 is provided in the cutting fluid collection tank 31. Both the left chip baffle 321 and the right chip baffle 322 are connected to the bearing part of the cutting fluid collection tank 31 through a plurality of screws or bolts. At the same time, the left chip baffle 321 and the right chip baffle 322 are inclined towards the notch of the chip guide groove 11 to form a guide for the flow of the cutting fluid.

[0037] On the basis of the above embodiment, an arc surface is provided on the chip guide groove 11, and the radian of the arc surface is the same as that of the spiral part of the screw rod 13.

[0038] On the basis of the above embodiment, as Figure 5As shown in the figure, the cutting fluid recovery tank 33 is installed at the end of the cutting fluid collection tank 31 and has an L-shaped structure. The cutting fluid collection tank 31 is provided with a cutting fluid concentration chamber 311 and a cutting fluid transition chamber 312 at intervals. The cutting chip filter tank 32 is arranged in the cutting fluid concentration chamber 311, and directly above the cutting chip filter tank 32 is the liquid outlet of the machine tool body 4.

[0039] The cutting fluid recovery tank 33 is provided with a cutting fluid filtration chamber 331 and a cutting fluid recovery chamber 332 at intervals. Among them, the cutting fluid filtration chamber 331 is connected to the cutting fluid transition chamber 312, and a first filter screen is provided between them. A second filter screen is provided between the cutting fluid filtration chamber 331 and the cutting fluid recovery chamber 332.

[0040] On the basis of the above embodiment, the chip removal cylinder 12 is installed in the cutting fluid transition chamber 312, placed at the end of the cutting fluid collection tank 31, and is connected to the chip guide groove 11.

[0041] On the basis of the above embodiment, as Figure 6 shown, the chip collection trolley 2 is arranged at the discharge end of the chip removal machine 1. A filter plate is arranged in the chip collection trolley 2, and a liquid outlet is opened at the bottom on one side of the chip collection trolley 2.

[0042] During use, the cutting chips generated by the machine tool body 4 during cutting process flow into the cutting chip filter tank 32 together with the cutting fluid. After being filtered by the left chip baffle 321 and the right chip baffle 322 to remove a part of the cutting fluid, they enter the cutting fluid concentration chamber 311. The filtered cutting chips enter the chip guide groove 11 under the action of gravity. At the same time, when the cutting fluid in the chip guide groove 11 reaches a certain height, it can overflow to the outside of the left chip baffle 321 and the right chip baffle 322 on both sides and enter the cutting fluid concentration chamber 311. By driving the screw rod 13 to rotate through the motor, the screw rod 13 drives the cutting chips and the cutting fluid to move towards the chip removal cylinder 12. The cutting chips are pushed to the chip outlet above the chip removal cylinder 12 and discharged into the chip collection trolley 2.

[0043] The cutting fluid flows from the cutting fluid concentration chamber 311 to the cutting fluid transition chamber 312, and then enters the cutting fluid filtration chamber 331 through the first filter screen for secondary filtration; the cutting fluid entering the cutting fluid filtration chamber 331 enters the cutting fluid recovery chamber 332 again through the second filter screen for tertiary filtration before it can be recycled, which can help to further improve the machining accuracy of the machine tool.

[0044] To sum up:

[0045] A chip removal structure of a numerically controlled engraving machine according to the present utility model, the main structure of the cutting fluid filtering and recycling device is arranged in an L shape and placed at the bottom of the machine tool body. Due to the limited installation space at the bottom of the machine tool, the chip conveyor is installed in the cutting fluid filtering and recycling device, so that the structure of the entire chip removal structure is compact. The design of the discharge port of the chip conveyor further reduces the overall floor area of the machine tool and improves the utilization rate of the factory building land. At the same time, three-stage filtration is arranged in the cutting fluid filtering and recycling device to obtain cutting fluid with high purity through multi-stage filtration, improve the use efficiency and service life of the cutting fluid, and can assist in further improving the machining accuracy of the machine tool;

[0046] The chip removal structure of the present utility model performs multi-stage filtration and recycling of the coolant while concentrating and discharging the cutting chips. The cutting fluid circulation treatment speed is fast and the purification effect is good.
