The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In one embodiment, the composite scraper chip removal machine comprises a shell, a driving device, a first guiding device, a second guiding device and a conveying device; the conveying device comprises a first endless chain, a second endless chain and a scraper, and the first endless chain and the second endless chain are arranged on two sides in the shell in parallel; the driving device is rotatably connected to one end of the first endless chain and one end of the second endless chain, the first guide device is connected to the other end of the first endless chain and the other end of the second endless chain, and the second guide device is located between the driving device and the first guide device and is matched with the bottom layer chains of the first endless chain and the second endless chain; the driving device drives the first endless chain and the second endless chain to revolve along the first guide device and the second guide device in the shell; a partition plate is arranged in the shell and is positioned in the first endless chain and the second endless chain and close to the upper-layer chain; one end of the scraper is fixedly connected with the first endless chain, and the other end of the scraper is fixedly connected with the second endless chain; the working face extension of the scraper intersects the working face of the partition and/or the bottom of the housing.

Referring to fig. 1-2, the combined type scraper chip removal machine includes a housing 10 including a horizontal section and a lifting section. The highest part of the lifting section is provided with a driving device 20, one end of the horizontal section far away from the lifting section is provided with a first guiding device 30, and the intersection of the lifting section and the horizontal section is provided with a second guiding device 40. The conveyor 50 encloses the drive, the first guide and the second guide. Specifically, the driving device comprises a driving chain wheel and a driving motor, wherein the driving chain wheel is arranged on two sides in the shell through a shaft and is driven to rotate by the driving motor. This configuration is conventional in the art and the present embodiment will not be described in detail. Further, the conveyor includes a first endless chain 51, a second endless chain 52, and a scraper 53, which are disposed in parallel on both sides of the housing and one end of which is wrapped around the driving sprocket and the other end of which is wrapped around the first guide. The second guide means is located between the first endless chain and the second endless chain and cooperates with the bottom chain. Thus, the driving motor is started to drive the first endless chain and the second endless chain to rotate in the shell along the first guide device and the second guide device.

In order to realize the chip removal function of the scraper chip removal machine, a plurality of scrapers are fixedly arranged between the first endless chain and the second endless chain at intervals. Further, a partition plate 11 is arranged in the shell 10, is positioned in the first endless chain and the second endless chain, and has a working surface parallel to the running track of the upper endless chain. Most preferably, the baffles are welded to both sides of the housing and adjacent to the upper endless chain. One end of the chain wheel is close to the driving chain wheel, and the other end of the chain wheel is close to the first guiding device. It should be noted that the first guiding device may be a connecting shaft structure, and the annular chain rolls around the connecting shaft structure; it is also possible to have a sprocket combination that revolves by meshing with an endless chain. More specifically, the face extension of the scraper intersects the face of the partition and/or the floor of the housing such that a debris ejection passage is defined between the scraper and the partition and the floor of the housing. When the annular chain runs, the chips on the partition plate can be scraped out by the chip removal channels of the scraper and the partition plate, and the chips in the shell can be scraped out by the chip removal channels of the scraper and the bottom plate of the shell. When long scraps need to be discharged, the annular chain and the scraping plates are divided into two layers by the partition plates, so that the upper scraping plates and the lower scraping plates cannot be wound by the long scraps. When the wet processing needs to convey the light-weight chips, the cutting fluid leaks to the bottom through the partition plate, the chips are left on the partition plate and are discharged through the scraper, and the floating problem is avoided. The multipurpose of one machine is realized, and the universality is greatly improved. And the chip removal machine has two chip removal channels, can rotate clockwise or anticlockwise according to the operating condition, need not to change the structure, and the commonality is strong and application scope is big. The conventional chip cleaner only has one chip removal channel, and the chip cleaner can only run along one direction, so that the limitation is large.

Optimally, the scraper is attached to the working surface of the partition plate and the bottom plate of the shell, and the scraper is perpendicular to the partition plate and the bottom plate when in operation, so that the chip removal efficiency is highest and the chip removal is most thorough.

Furthermore, the second guide device can be rotatably connected with the first endless chain and the second endless chain, and the guide compression of the endless chains can be better realized by meshing with the endless chains.

In an embodiment, the second guiding device can be used as a filtering device to filter the cutting fluid in the chip removal machine, so that the chip removal machine can realize the dual functions of chip removal and filtering under the condition of not changing the original structure. Specifically, referring to fig. 2, the second guide 40 includes a first fixing portion 41, a second fixing portion 42, a first rotating portion 43, a second rotating portion 44, and a filter screen 45. The first fixing part and the second fixing part are symmetrically fixed on two sides of the shell respectively, and coaxial through holes are formed in the middles of the side faces respectively and used for enabling filtered cutting fluid to flow out. One ends of the first rotating part and the second rotating part, which are deviated from each other, are respectively embedded into the through holes of the first fixing part and the second fixing part; the opposite ends of the first revolving part and the second revolving part are fixedly connected with the two sides of the filter screen through the hose clamp to form a whole. The first rotating part and the second rotating part are provided with connecting parts matched with the first annular chain and the second annular chain between the filter screen and each fixing part; when the first endless chain and the second endless chain run, the first revolving part, the second revolving part and the filter screen are driven to rotate. The cutting fluid in the shell is filtered by the filter screen and then discharged from the through hole of the fixing part through the shell for use by a machine tool, and the chips are discharged by the scraper.

In an embodiment, in order to simplify the filtering structure of the second guiding device, improve the sealing performance, and reduce the use of the sealing ring, referring to fig. 3, the first fixing portion 41 includes a circular end cover plate 411 and a fixing ring 412 coaxially disposed with the circular end cover plate. Specifically, a side surface of the fixing ring 412 is provided with a groove coaxial with the fixing ring, the fixing ring is mounted on the circular end cover plate 411 through a bolt, and the groove faces the circular end cover plate, so that an annular cavity is formed between the groove and the circular end cover plate. A through hole is arranged at the position of the circular end surface cover plate matched with the cavity and is externally connected with a water inlet pipe. Optimally, the water inlet pipe is externally connected with filtered clean liquid with certain pressure.

Further, the casing is opened at the crossing department of horizontal segment and promotion section has the solid fixed ring's of matching round hole, and solid fixed ring passes the round hole and arranges the casing in, and then the circular end cover plate passes through bolt fixed connection near solid fixed ring's one side and casing. It should be noted that the first fixing portion and the second fixing portion are the same and symmetrically installed on both sides of the housing. The first turning portion 43 includes a first ring 431, a second ring 432, and a sprocket 433. The first circular ring is sleeved on the outer circular surface of one end of the second circular ring. Preferably, the first ring is sleeved in the middle of the second ring and is connected with the second ring into a whole in the radial direction through a plurality of bolts. The chain wheel 433 is sleeved on one end of the first circular ring close to the second circular ring and welded on the first circular ring. One end of the first circular ring, which is far away from the second circular ring, penetrates through the fixing ring to be embedded into the rear circular end cover plate, and at the moment, the chain wheel is meshed with the first annular chain. The first circular ring and the second circular ring can be driven to rotate relative to the fixing ring and the circular end face cover plate through the operation of the annular chain.

It should be noted that the second rotating portion can be the same as the first rotating portion in structure and installation manner, and after the second rotating portion is matched with the second fixing portion, the chain wheel on the second rotating portion is meshed with the second endless chain. The filter screen can be made of polyurethane square filter screen and wraps the second circular rings at the two ends through the throat hoop, or can be made of metal cylindrical filter screen and is sleeved on the second circular rings at the two ends and is hooped tightly through the throat hoop. Thus, the filter screen, the first circular ring and the second circular ring form a sealed cavity.

In one embodiment, the sealing structure is more reliable in order to make the structure of the rotating part and the fixing part more compact. The one end that is close to circular terminal surface apron at first ring is equipped with protruding ring, and one side of protruding ring is close to solid fixed ring groove open-ended one side, and the one side parallel and level that the casing is close to with circular terminal surface apron to the another side. Preferably, the groove of the fixing ring has a square cross-section such that the side of the groove adjacent to the first ring is flush with the outer circumferential surface of the raised ring. The fixed part still is provided with sealing ring 413, and the sealing ring is located solid fixed ring square groove and the interior anchor ring is close to the outer disc of protruding ring. The two sides of the sealing ring are respectively close to the bottom surface of the direction groove and the circular end surface cover plate. Thus, a labyrinth structure is formed among the first circular ring, the fixed ring and the sealing ring. Debris outside the filter screen can be more effectively prevented from entering the filter screen. It should be noted that the outer ring of the sealing ring is located in the through hole of the end cover plate, that is, the sealing ring is located on the smallest ring of the annular cavity.

Referring to fig. 1 again, when the chip removal machine works, chips and cutting fluid discharged from the machine tool enter the chip removal machine chip receiving port 60, and the chips are discharged out of the chip removal machine through the scraper and are uniformly processed. After the cutting fluid is filtered by the filter screen, the filtered cutting fluid flows out of the shell from the circular holes in the middle of the first circular ring, the fixing ring and the end cover and is reused by the machine tool; and a part of the filtered cutting fluid is pumped into the annular cavity through the water inlet pipe under high pressure. At the moment, the cutting fluid pressure in the annular cavity is higher than that in the outside, the filtered cutting fluid flows out from the inside to the outside from a gap at the position, close to the protruding circular ring structure on the outer side of the first circular ring, of the annular cavity, the filtered cutting fluid effectively prevents the cutting fluid before filtering from entering the circular ring from the gap, and further prevents the cutting fluid before filtering from entering a region of the filtered cutting fluid. Namely, a dirty liquid cavity is formed between the filter screen and the chip remover shell, a clean liquid cavity is formed inside the filter screen, and the filtered cutting liquid and the unfiltered cutting liquid are dynamically separated through the structures of the rotary part and the fixed part, so that the high-precision filtering of the cutting liquid is realized.

The whole process does not need a damageable sealing element, reliably solves the problems of sealing and filtering failure, improves the filtering precision of the cutting fluid, prolongs the service life of the filtering structure and reduces the maintenance cost.

In one embodiment, in order to further reduce the manufacturing accuracy and the fitting accuracy of the first ring and the second ring, and also in order to achieve the sealing performance of the first ring and the second ring in fitting, a rubber seal is embedded in a portion where the first ring and the second ring overlap. Specifically, a groove matched with the sealing ring is formed in the outer circle surface of the second circular ring, the sealing ring is sleeved on the groove, and the first circular ring is sleeved on the outer circle of the sealing ring. Preferably, the height of the sealing ring protruding out of the second circular ring is larger than the gap between the first circular ring and the second circular ring. Even if the manufacturing and matching precision of the first circular ring and the second circular ring is reduced, the sealing performance between the first circular ring and the second circular ring cannot be influenced by the elastic expansion of the sealing ring. The static seal has the advantages of simple structure, convenient use, reliable seal, long service life and no need of frequent maintenance.

In an embodiment, in order to ensure the universality, realize the standardized design and manufacture, further control the cost and simplify the structure, the second guiding device of the combined type scraper chip removal machine can adopt an end cover guide rail assembly which is symmetrically arranged at two sides of the shell. Referring to fig. 4, the end cap rail assembly includes a cover plate 46, an arcuate rail 47, and a rail support 48. Specifically, the guide rail supports have three, and the equipartition sets up. And one end of the connecting rod is welded with the cover plate, and the other end of the connecting rod is fixedly connected with the guide rail through a bolt. The cover plate is fixedly connected to the outer side of the shell through uniformly distributed bolts 49, and the guide rail extends into the shell, and the arc-shaped surfaces at the bottom of the guide rail are respectively compacted to the annular chains at two sides. At this point a conventional flight chip ejector is formed.

When the combined type scraper blade chip removal machine was used in the occasion that the filtration requirement is high, only needed to change the end cover guide rail set spare of casing both sides for taking the drum of filter screen, was about to loosen bolt 49 on the conventional scraper blade chip removal machine, took off end cover guide rail set spare, then changed for taking the drum of filter screen. The structure of the chip removal machine is not required to be changed, the machine is multifunctional, and the universality is greatly improved. It should be noted that the guide rail support may also be directly fixedly connected with the guide rail, and then connected with the cover plate through a bolt. The arc of the guide rail is matched with the running track of the annular chain.

Referring to FIG. 5, in one embodiment, the blade is made using a flat laser or die or machining operation to make a flat blade 531. Connecting seats are welded at the two ends of the connecting seat, and holes are formed in the connecting seats and connected with accessories of the annular chain. Optimally, the scraper is vertical to the bottom surface of the partition board or the shell, so that the scraper is steep, the adhesion of chips can be avoided in the chip removal process, and the chip removal is smoother.

Referring to fig. 6, in one embodiment, in order to avoid carrying cutting fluid during chip removal by the scraper, a plurality of through holes are formed at intervals in the width direction of the casing in the scraper, and a scraper 532 with holes is formed for backflow of the cutting fluid. Optimally, the through hole is a rectangular hole with a large length-width ratio, the chips are blocked in a chip removal channel formed by the scraper and the partition plate or the bottom plate and are discharged in the chip removal process, and the chip liquid leaks in the shell through the hole, so that the cutting liquid is prevented from being carried in the chip removal process, and the waste can be reduced. On the other hand, the discharged cuttings are drier and convenient for subsequent recovery.

Referring to fig. 7, in an embodiment, in order to improve the strength and the chip removal amount of the scraper of the chip removal machine, the scraper may be an arc-shaped scraper 533 with an arc-shaped cross section, and specifically, one end of the scraper may be bent along the running direction of the endless chain to form an arc-shaped scraper. The middle positions of the two sides of the arc-shaped scraper can also be provided with a connecting seat to be fixedly connected with the annular chain.

In order to meet different working conditions or use requirements, the scraper of the chip removal machine can be a flat plate, and the scraper with a water return hole and the arc-shaped scraper can be combined randomly for use. For example: when the chip removal machine needs to process chips which have larger specific gravity and are not easy to float, the chips and cutting fluid generated by machine tool processing enter from the chip receiving port 60, firstly fall onto the partition plate 11, the annular chain runs clockwise, the chips enter below the partition plate through the rear shaft, and the chips can be discharged from the chip removal port from a chip removal channel formed by the chips and the bottom of the shell by adopting the flat scraper 531 or the scraper 532 with holes.

When the chip removal machine needs to process chips which are small in specific gravity and easy to float, chips and cutting fluid generated by machining of a machine tool enter from the chip receiving port 60, firstly fall onto the partition plate 11, the annular chain runs anticlockwise, and the chips can be scraped out from a chip removal channel formed by the chips and the partition plate along the upper surface of the partition plate by adopting the straight flat plate 531 or the scraper 532 with the water return hole or the arc-shaped scraper 533 and then are discharged from the chip removal port. A small amount of chips are brought under the partition plate along the flow of cutting fluid, and the flat plate 531 or the scraper 532 with return holes or the arc-shaped scraper 533 can still bring the part of chips back to the upper side of the partition plate through the rear shaft to be discharged from the lower side of the partition plate along with the counterclockwise running of the endless chain. Therefore, the cutting scraps between the upper layer scraper and the lower layer scraper can be reduced, the working environment is improved, the service life of equipment is prolonged, and the device is particularly suitable for a structure with filtering.

It should be noted that, when the chip removing machine needs to process smaller chip particles, preferentially, the chip removing machine selects the flat plate 531, so that the conveying efficiency and the conveying effect can be improved to the greatest extent. The chip size that needs to handle when the chip removal machine is great, preferential, the chip removal machine chooses for use to take the straight scraper 532 in return water hole, can effectively reduce the cutting fluid and take out and can avoid the smear metal to reveal from the return water hole again. When the chip removing machine needs to treat a large amount of chips, preferably, the chip removing machine selects the arc-shaped scraper 533. Because the arc-shaped scraper has higher strength, the arc-shaped scraper is not easy to deform. And when the arc-shaped scraper is selected, the annular chain needs to rotate anticlockwise, so that the cuttings are discharged through a channel formed by the partition plate and the scraper. The problem that a large amount of cuttings are blocked at the bottom of the shell through the rear shaft is avoided. The arc scraper blade can adopt the sheet metal component to carry out the multichannel and bend, and on the one hand the increase strength, on the other hand the sheet metal component can design wantonly according to the operating mode, and it is all comparatively convenient to draw materials and make.

Because the scraper blade both can form the chip removal passageway with the baffle in this application, can form the chip removal passageway with the casing bottom again, it both can clockwise operation and can anticlockwise operation. Therefore, a user can select a proper running direction according to different working conditions, only different buttons are needed to be operated, the structure of the chip cleaner is not needed to be changed, and the universality is high. And the second guider can set up to the pivoted structure and also can set up to fixed knot structure, and the corresponding chip cleaner that becomes to have filtering chip removal function and the chip cleaner of ordinary chip removal need not to change the structure, only need to dismantle the bolt can. The interchangeability is high, the function is strong, the standardization degree in the aspects of design, production, manufacture, use and model selection is high, and the universality is strong; and the space is selected for transmission, and the application range is wider.
