Description

Technical Field

[0001] The utility model relates to a chip removal filter device and belongs to the technical field of chip removal machines. Background Art

[0002] In the process of machine tool processing, especially in wet machine tool processing, chip removal and cutting fluid treatment are the key links to ensure the efficient and stable operation of the machine tool. The scraper chip conveyor is a common chip removal device that uses a chain to drive the scraper to separate the chips from the cutting fluid and transport them to the designated chip removal location or chip collection box. The scraper chip conveyor is driven by a reducer. The chips first settle on the bottom plate of the chip conveyor. The chain drives the scraper plate to scrape the chips out of the chip conveyor along the bottom plate of the chip conveyor. Due to its high cleaning efficiency, simple operation, reliable operation, stable performance, quantitative chip removal, no overload, convenient disassembly and assembly, and easy maintenance, it is widely used in machine tool processing. The main task of the chip removal device is to discharge the chips generated during the cutting process from the machine tool to avoid interference or damage to the operation of the machine tool caused by the chips. At the same time, the cutting fluid plays a role in cooling, lubricating and cleaning during the processing process. Therefore, filtering the cutting fluid to remove the chips and other impurities in it is crucial to maintain the cleanliness of the cutting fluid and extend its service life. At present, the common scraper-type chip conveyors on the market not only remove chips, but also have a certain filtering function. A filter is installed inside the scraper-type chip conveyor to filter the liquid to meet the filtering accuracy of the chip flushing pump. However, in the existing machine tool processing and production, the chip conveyor is generally required to consider the flow rate and prevent mesh clogging during filtering, so the filter material mesh used is larger, resulting in a relatively low filtering accuracy of the scraper-type chip conveyor. The discharged chip liquid still contains a large amount of debris, resulting in a decrease in the cleanliness of the chip liquid and affecting the service life of the chip liquid.

[0003] Therefore, a chip removal and filtering device is needed to improve the filtering accuracy of the chip fluid, thereby improving the cleanliness of the chip fluid and ensuring the service life of the chip fluid. Utility Model Content

[0004] The utility model aims at solving the defects of the prior art and provides a chip removal and filtering device.

[0007] The beneficial effects of the utility model are:

[0008] The utility model discharges most of the chips in the chip liquid through a scraper-type chip conveyor. The chips first settle on the bottom plate of the scraper-type chip conveyor. The scraper conveying mechanism drives the scraper to scrape the chips out of the machine along the bottom of the chip conveyor. The dirty liquid containing a large amount of impurities in the scraper chip conveyor is coarsely filtered through a coarse filtering mechanism. The chip liquid after coarse filtration enters a vertical paper belt filter. The vertical paper belt filter further filters fine chips and impurities, so that a large amount of fine chips and impurities in the chip liquid are adsorbed by the paper belt. The chip liquid filtered by the vertical paper belt filter has high cleanliness, thereby improving the service life of the chip liquid.

[0016] The beneficial effect of adopting the above further technical solution is: the scraper is driven to rotate by the first chain and the second chain to discharge the chips, and the filter frame is arranged between the upper and lower scrapers to avoid the filter frame interfering with the work of the scraper.

[0017] Furthermore, the scraper type chip conveyor also includes a chain power mechanism, and the chain power mechanism drives the first chain and the second chain to rotate.

[0018] Furthermore, the vertical paper belt filter comprises a filter housing, the filter housing is provided with a filter liquid inlet, and the filter liquid inlet is connected to the filter frame liquid outlet through a pipeline.

[0019] The beneficial effect of adopting the above further technical solution is: the filter frame and the vertical paper belt filter are connected through a pipeline, and the vertical paper belt filter is arranged below the scraper type chip conveyor. The chip liquid can fall into the vertical paper belt filter in the pipeline by gravity, and the structure is simple.

[0020] Furthermore, the vertical paper belt filter includes filter paper, a mesh chain, a mesh chain driving mechanism, a paper pressing roller and a paper feeding signal transmission mechanism. A paper outlet and a paper inlet are respectively provided on both sides of the filter housing. A water tank is provided in the filter housing and is located below the mesh chain.

[0021] The beneficial effects of adopting the above further technical scheme are: the network chain is driven to rotate by the network chain driving mechanism, the filter paper is driven to feed by the network chain and the paper pressing roller, the liquid level in the vertical paper belt filter is detected by the paper feeding signal transmission mechanism, and the paper replacement is notified in time, thereby realizing automatic replacement of the paper belt, and the clean chip liquid filtered by the vertical paper belt filter is received by the water tank.

[0022] Furthermore, the network chain driving mechanism includes a speed reducer, a driving roller arranged between the paper pressing roller and the paper outlet, and a driven roller arranged between the paper pressing roller and the paper inlet, and the speed reducer is drivingly connected to the driving roller.

[0024] Furthermore, the network chain driving mechanism also includes a first limiting roller and a second limiting roller respectively arranged below the driving roller and the driven roller, and a third limiting roller arranged between the driving roller and the paper pressing roller, and the network chain sequentially passes around the driving roller, the first limiting roller, the second limiting roller, the paper pressing roller, the third limiting roller and the driven roller.

[0025] The beneficial effect of adopting the above-mentioned further technical solution is: the running trajectory of the mesh chain is limited by the first limiting roller, the second limiting roller, and the third limiting roller, thereby reducing the inclination of the vertical surface of the chip discharge side of the mesh chain, preventing loose chips from falling back into the vertical paper belt filter, and achieving stable discharge of chips.

[0026] Furthermore, the paper feeding signal transmitting mechanism includes a signal transmitter, a liquid level sensor and a detection float.

[0027] Furthermore, the vertical paper belt filter also includes a dirt collecting box, which is arranged outside the filter housing and below the paper outlet. A photoelectric switch is provided at the paper inlet of the vertical paper belt filter.

[0028] The beneficial effect of adopting the above further technical scheme is: when working, the chip liquid containing a large amount of chips and impurities flows into the vertical paper belt filter after preliminary filtration by the scraper chip conveyor and the coarse filtering mechanism. The paper belt in the vertical paper belt filter is sealed and evenly formed into a concave cavity. When the chip liquid passes through the paper belt, fine chips and impurities are adsorbed on the upper surface of the paper belt, and the chips and impurities gradually accumulate until the paper belt is blocked. At this time, the dirty liquid level in the vertical paper belt filter rises, and the liquid level lifts the detection float. When the detection float moves up to the liquid level sensor, the transmitter sends a signal, and the reducer drives the driving roller and the mesh chain to move, and the accumulated chips, impurities and dirty paper belt are discharged into the dirt collection box, thereby realizing the automatic replacement of the paper belt; after the paper belt is updated, the dirty liquid level drops accordingly, the reducer stops working, and the machine enters the next working cycle. A photoelectric switch is provided at the paper inlet of the vertical paper belt filter, which can give a timely warning when the filter paper is used up, reminding people to replenish the filter paper in time.
