[0022] The chip removal and recycling cleaning mechanism 6 further comprises a liquid discharge collecting device for primary filtering and recycling of metal chips in the chip removal device, the liquid discharge collecting device comprising a liquid discharge shaft 607, one side surface of the liquid discharge shaft 607 being rotatably connected with a liquid discharge plate 608, one end of the liquid discharge plate 608 away from the liquid discharge shaft 607 being fixedly connected with a filter plate 609, the liquid discharge plate 608 being provided with a liquid outlet hole 610 at the end away from the liquid discharge shaft 607, and the inner side of the liquid discharge plate 608 being provided with a water collecting groove 611, the liquid discharge collecting device being started to work in the deep cleaning and recycling stage, when the inclined starting device drives the base frame 2 to move upward, the liquid discharge plate 608 is in an inclined state through cooperation of the liquid discharge shaft 607 and the engagement block 618 and linkage of the connecting rack column 612, the specific process being as follows: since the liquid discharge shaft 607 is fixedly connected with the base frame 2, the engagement block 618 is fixedly connected with the protective shell 617, and one end of the liquid discharge plate 608 is connected with the liquid discharge shaft 607 and the other end is connected with the engagement block 618, when the driving motor 616 drives the base frame 2 to move as a whole through the connecting rack column 612, one end of the liquid discharge plate 608 is displaced while the other end is not, so that the liquid discharge plate 608 is inclined, the liquid discharge shaft 607 cooperates with the inclined structure to utilize gravity to assist the flow of the mixture, at this time, the mixture of metal chips and cutting fluid generated by the spray head 605 is flowed along the inclined liquid discharge plate 608, the mixture first contacts the filter plate 609 and then is discharged through the liquid outlet hole 610 to realize recycling, the combination of the filter plate 609 and the water collecting groove 611 realizes primary separation of solid and liquid, which facilitates chip recycling and reduces cutting fluid waste, and the metal chips are intercepted by the filter plate 609 and remain on the surface of the liquid discharge plate 608, which are manually collected after cleaning is completed.

[0023] The chip removal and recycling cleaning mechanism 6 further comprises an inclination starting device for preparing the liquid discharge collecting device before filtering and recycling, the inclination starting device comprises four groups of connecting rack columns 612 fixedly connected below the base frame 2, one side of the connecting rack column 612 is engaged with a driving gear 613, the other side surface of the driving gear 613 is engaged with a driven gear 614, one side surface of the driving gear 613 and the driven gear 614 is fixedly connected with a transmission rod 615, one side surface of the transmission rod 615 is fixedly connected with a driving motor 616, the outer side of the driving gear 613 and the driven gear 614 is provided with a protective shell 617, the upper surface of the protective shell 617 is fixedly connected with a clamping block 618, the inclination starting device starts working before deep cleaning and recycling, and prepares the liquid discharge collecting device: after starting the driving motor 616, the driving motor 616 drives the transmission rod 615 to rotate, and the transmission rod 615 synchronously drives the driving gear 613 and the driven gear 614 to rotate; because the driving gear 613 and the driven gear 614 are engaged with the connecting rack column 612, and the connecting rack column 612 is arranged at four corners below the base frame 2, the rotation of the gears drives the connecting rack column 612 to move upward, and the upper surface of the protective shell 617 is fixedly connected with the clamping block 618, the clamping block 618 is slidably connected with one end of the liquid discharge plate 608, so that one end of the liquid discharge plate 608 is displaced upward, and because the main shaft 601 is connected with the base frame 2, when the base frame 2 moves upward, the liquid discharge plate 608 of the liquid discharge collecting device rotates around the liquid discharge shaft 607, so that the liquid discharge plate 608 is finally in an inclined state, the size and the number of teeth of the driving gear 613 and the driven gear 614 are matched, and the four-corner connecting rack column 612 can stably lift the base frame 2, so as to ensure that the inclination angle of the liquid discharge plate 608 is uniform.

[0024] Further, the two groups of upper slots 602 can rotate around the main shaft 601 to align the side surfaces of the two groups of upper slots 602, the main shaft 601 enables flexible rotation of the upper slots 602, facilitates adjustment of the opening and closing state, and the two groups of upper slots 602 can be fixedly connected with each other after the side surfaces are aligned through the lock buckle 603, the lock buckle 603 ensures stable connection after alignment, provides a closed environment for the pushing and cleaning mechanism 5, avoids scattering of chips during cleaning, and improves operation safety and cleaning effect. When a closed cleaning space needs to be built, the worker rotates the slot 602 to make the two groups of upper slots 602 rotate around the main shaft 601 symmetrically installed on the base frame 2, until the side surfaces of the two groups of upper slots 602 are completely aligned and fitted, and then the lock buckle 603 is used to firmly fix the two groups of upper slots 602 after alignment.

[0025] Further, the lower slot 604 is rotationally connected with the base frame 2 around the main rotating shaft 601, and the two groups of upper slots 602 are rotationally connected and form a closed space with the lower slot 604, and the twenty-five groups of spray heads 605 are symmetrically arranged at equal intervals in the two groups of upper slots 602. In use, the twenty-five groups of spray heads 605 can fully flush the chip removal helical rotating knife 4 and the lower slot 604. Compared with manual cleaning of the device, manual cleaning cannot clean the dead angles due to the non-dismountable design of the traditional device. After the upper slot 602 and the lower slot 604 are opened and closed, the corresponding places are sprayed by the spray head 605, which effectively improves the cleaning intensity and efficiency.

[0026] Further, the liquid discharge plate 608 is symmetrically provided with a strip-shaped slot near the outer surface of the filter plate 609, and the water collecting tank 611 is provided with four groups inside the liquid discharge plate 608. In the residual self-cleaning stage, the two groups of upper slots 602 are rotated to align around the main rotating shaft 601 and are fixed by the lock buckle 603, and together with the lower slot 604 below, they form a closed space to provide a closed environment for the pushing and cleaning mechanism 5 to clean the residual chips. The closed space can prevent chips or cleaning liquid from splashing during cleaning, ensuring a clean working environment. In the deep cleaning stage, the twenty-five groups of spray heads 605 inside the two groups of upper slots 602 in the closed space are activated to spray cleaning liquid onto the inner wall of the lower chip removal helical rotating knife 4 and the lower slot 604. The arrangement of the twenty-five groups of spray heads 605 at equal intervals can achieve omnidirectional flushing.

[0027] The synchronous mechanism 7 is used to realize the linkage of the tilting starting device and the slot double-opening device. The synchronous mechanism 7 includes two groups of fixed blocks 701 installed inside the base frame 2, short rods 702 rotationally connected to the two sides of the fixed blocks 701, long rods 703 rotationally connected to the other ends of the two groups of short rods 702, the two groups of long rods 703 rotationally connected at one end, push rotating blocks 704 rotationally connected to the other ends of the two groups of long rods 703, and sliding rods 705 rotationally connected to the connecting ends of the two groups of long rods 703. In use, the base frame 2 rises due to the rotation of the driving motor 616, at which time the fixed blocks 701 rise synchronously, and the sliding rods 705 relatively descend. The long rods 703 will rotate around the connecting points of the sliding rods 705 and the long rods 703 by the upward pushing force of the short rods 702 on the long rods 703. Finally, the long rods 703 apply an outward pushing force to the lower slot 604 through the push rotating block 704, realizing the mutual linkage among the liquid discharge and collection device, the tilting starting device, and the slot double-opening device.

[0028] Further, the pushing and cleaning mechanism 5 comprises a latching device 501, model Takigen C-1414, which is installed on the base frame 2, one side of the latching device 501 is fixedly connected with a displacement block 502, one side surface of the displacement block 502 is slidably connected with two groups of spring L-shaped telescopic columns 503, one end of each of the two groups of spring L-shaped telescopic columns 503 is fixedly connected with a fixed push plate 504, the lower side of the fixed push plate 504 is rotatably connected with a rotating push plate 505, the fixed push plate 504 and the rotating push plate 505 are both arc-shaped structures matched with the inner walls of the upper slot 602 and the lower slot 604, the inside of the displacement block 502 is provided with a displacement motor 506, the outside of the displacement motor 506 is provided with a waterproof casing matched therewith, one side of the displacement motor 506 is connected with a gear set 507, one side of the gear set 507 is connected with a driving rotary drum 508, in use, the displacement motor 506 is started, the displacement motor 506 drives the driving rotary drum 508 to rotate through the gear set 507, since the outer side surface of the driving rotary drum 508 is slightly higher than the height of the outer side surface of the displacement block 502, and the outer side surface of the driving rotary drum 508 is an elastic anti-slip plastic, therefore, when the two upper slots 602 are closed, the driving rotary drum 508 will be tightly attached to one side surface of the upper slot 602, so that the driving rotary drum 508 has a large enough friction force to drive the pushing and cleaning mechanism 5 to displace, under the driving of the driving rotary drum 508, the displacement block 502 displaces towards one end of the chip removal pipe 3, the fixed push plate 504 and the rotating push plate 505 provided on the side surface of the displacement block 502 will extrude and remove the dead angle part of the chip removal groove, wherein the fixed push plate 504 and the rotating push plate 505 are rotatably connected with each other, the rotating push plate 505 can rotate around the fixed push plate 504, but since the spring L-shaped telescopic column 503 is provided, the rotating push plate 505 will be blocked when rotating towards the displacement block 502, which will make the displacement block 502 displace towards the chip removal pipe 3 with the fixed push plate 504 and the rotating push plate 505 in a fully open state, when the pushing and cleaning mechanism 5 completes a chip pushing work and returns to the original position, the rotating push plate 505 will rotate, thereby opening a channel for the space below, such a setting can prevent the pushing and cleaning mechanism 5 from pushing the chips back during the returning process, thereby improving the chip removal effect of the device.

[0029] Further, the outer surface of the driving drum 508 is made of elastic anti-skid plastic, and is slightly higher than the outer surface of the displacement block 502. A circular hole is formed in the middle of the two groups of fixed push plates 504 and rotating push plates 505, and the size of the circular hole is consistent with the cross-sectional size of the chip removal spiral rotating knife 4. When in use, the elastic anti-skid plastic material of the driving drum 508 can effectively adhere to the surface of the upper slot 602 and the protective shell 617 after they are closed, and the elastic anti-skid plastic can provide excellent friction to provide excellent frictional driving force for the pushing and cleaning mechanism 5 and the protective shell 617. The circular hole formed in the middle of the fixed push plate 504 and the rotating push plate 505 has a size consistent with the cross-sectional size of the chip removal spiral rotating knife 4, which can prevent interference between the chip removal spiral rotating knife 4 and the fixed push plate 504 and the rotating push plate 505 when the device pushes the iron chips, thereby preventing damage to the device caused by abrasion.

[0030] Working principle, the overall working process of the machining center spiral chip removal device is divided into three stages of conventional chip removal, residual self-cleaning and deep cleaning and recovery. The first stage is conventional chip removal: the workers rotate the two groups of upper slots 602 around the main shaft 601 to open them, so that the two groups of upper slots 602 are away from each other. At this time, the lower slots 604 are in the initial state of mutual closure under the action of the synchronous mechanism 7, and form a chip removal channel with the base frame 2 for conveying chips. The chips generated by metal processing enter the collection from the opening of the upper slot 602, and the chips are concentrated on the spiral blade position connected with the spiral rotating knife 4 as the initial starting point. After the collection of the chips is completed, the two groups of upper slots 602 are rotated to close around the main shaft 601, and the lock catch 603 fixes the two groups of upper slots 602 to each other to form a closed conveying space. The transmission motor 1 is started to drive the chip removal spiral rotating knife 4 to rotate, and the chip removal spiral rotating knife 4 continuously conveys the chips to the chip removal pipeline 3 through the spiral blade.

[0031] The second stage, residual self-cleaning: after the output of the batch of debris by the debris discharge pipeline 3, the locking device 501 is unlocked, the displacement motor 506 drives the driving cylinder 508 to rotate through the gear set 507, the driving cylinder 508 is made of elastic anti-skid plastic, and when the driving cylinder 508 rotates, a friction force can be generated between the driving cylinder 508 and the inner wall of the upper slot 602 in the closed space, the displacement block 502 moves axially along the debris discharge helical rotary knife 4, when the displacement block 502 moves, the two groups of spring L-shaped telescopic columns 503 on one side of the displacement block 502 drive the fixed push plate 504 to move synchronously, the rotating push plate 505 below the fixed push plate 504 remains unfolded and cannot rotate excessively due to the support of the spring L-shaped telescopic columns 503; the central hole between the fixed push plate 504 and the rotating push plate 505 is consistent in size with the cross section of the debris discharge helical rotary knife 4, and in the moving process, the fixed push plate 504 and the rotating push plate 505 can tightly adhere to the blade helix of the debris discharge helical rotary knife 4 and the inner wall of the slot, so that the residual debris adhered to the inner walls of the upper slot 602 and the lower slot 604 and the helical blades can be scraped off, and finally the residual debris is pushed out through the debris discharge pipeline 3; after the cleaning is completed, the displacement motor 506 reverses to drive the displacement block 502 to return to the original position, if there are still residual debris that has not been cleaned when the displacement block 502 returns to the original position, the rotating push plate 505 cannot be supported by the spring L-shaped telescopic columns 503, so the rotating push plate 505 can rotate around the fixed push plate 504 to avoid bringing the residual debris back.

[0032] The third stage, deep cleaning: after the fixed push plate 504 is reset, the water pipe interface 606 is connected to the water pump to supply water to the twenty-five groups of nozzles 605, the nozzles 605 cross the surface of the debris discharge helical rotary knife 4, the inner walls of the upper slot 602 and the lower slot 604 to spray water containing cleaning agent, and the oil stains and residual debris are washed away; at the same time, the driving motor 616 is started to drive the driving gear 613 and the driven gear 614 to rotate through the transmission rod 615, and the connecting rack column 612 is driven to move upward to push the entire basic frame 2 to move upward; during the upward movement of the basic frame 2, the sliding rod 705 of the synchronous mechanism 7 is fixed with the protective shell 617, so the position of the sliding rod 705 does not change, the short rod 702 moves upward with the basic frame 2 and pushes the long rod 703 to be unfolded and pushes the rotating block 704, so that the lower slot 604 rotates around the main rotating shaft 601 to be opened synchronously, thereby exposing the lower part of the basic frame 2, and the transmission motor 1 and the displacement motor 506 are started again to make the debris discharge helical rotary knife 4 rotate to further uniformly wash the blades, and the displacement motor 506 drives the driving cylinder 508 to continue reciprocating along the inner wall of the upper slot 602, so that the residual debris and stains on the fixed push plate 504 and the rotating push plate 505 are further washed.
