Description

Technical Field

[0001] The present invention relates to the technical field of cutting processing, and particularly relates to a cutting chip removal device and a cutting machine. Background Art

[0002] The process of denture processing mainly includes dry cutting and wet cutting processes. The dry cutting process mainly cuts the denture material by a specific tool without the participation of cutting fluid. In this process, dry chips mainly composed of denture material debris are generated. These dry chips are relatively small and dry, and are easy to fly around in the processing environment, which not only affects the processing accuracy, but also may pose a threat to the health of operators. Therefore, they need to be discharged in time. The wet cutting process uses cutting fluid to assist during cutting. The cutting fluid can effectively reduce the cutting temperature and improve the surface quality of processing. However, it will also generate wet chips containing a mixture of cutting fluid and denture material debris. These wet chips are in a paste or fluid state, with certain viscosity and fluidity, and also need to be discharged as soon as possible to avoid affecting the continuous progress of processing and the normal operation of the equipment.

[0003] At present, a dry-wet integrated cutting machine is commonly used in the prior art to simultaneously have dry cutting and wet cutting functions. However, in the chip removal system of a conventional dry-wet integrated cutting machine, its dry cutting and wet cutting pipelines are separately arranged, making the structure of the entire equipment complex, not only increasing the manufacturing cost of the equipment, but also improving the difficulty of later maintenance and repair of the equipment. In addition, due to the special properties of wet chips, the existing chip removal system is difficult to effectively separate the cutting fluid from the denture material debris, resulting in the equipment being extremely easy to be blocked by larger particles or viscous substances in the wet chips, thereby causing abnormal shutdown and alarm of the machine tool, seriously affecting the production efficiency of denture processing and the stability of the equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a cutting chip removal device and a cutting machine to solve the technical problems in the prior art that the chip removal system of the dry-wet integrated cutting machine is complex in structure and has a poor filtering effect on wet chips.

[0005] With the above concept, the technical solution adopted by the present invention is as follows:

[0006] On the one hand, the present invention provides a cutting chip removal device applied to a cutting machine. The cutting machine includes a main body, and the main body has a processing chamber inside. A cutting assembly is arranged in the processing chamber, and a chip removal port is opened on the processing chamber. The cutting chip removal device includes:

[0007] A guiding pipe communicating with the chip removal port. The guiding pipe has a first discharge end allowing dry chips to pass through and a second discharge end allowing wet chips to pass through;

[0008] An adsorption assembly communicating with the first discharge end for sucking out the dry chips through the first discharge end;

[0009] The filtering component includes a storage box and a filtering structure. The storage box and the second discharge end are communicated through the filtering structure. The wet chips flow out from the second discharge end and enter the storage box after being filtered by the filtering structure.

[0010] Preferably, the guiding pipe extends in the vertical direction. The second discharge end is arranged at the bottom of the guiding pipe, and the second discharge end is configured with a water-way one-way valve which communicates with the filtering structure; the first discharge end is arranged on the side wall of the guiding pipe, and the first discharge end is configured with a bridge-shaped elbow. The middle part of the bridge-shaped elbow bulges upward and bends and extends, and the bridge-shaped elbow communicates with the adsorption component.

[0011] Preferably, the filtering structure includes a collecting basket and a first filter screen. The collecting basket communicates with the second discharge end, the first filter screen is arranged on the collecting basket, and the collecting basket communicates with the storage box through the first filter screen.

[0012] Preferably, the storage box is horizontally divided into a precipitation box and a liquid collection box which are communicated with each other. The precipitation box and the liquid collection box are communicated with each other through a second filter screen. The collecting basket is detachably connected to the precipitation box and communicates with the precipitation box through the first filter screen.

[0013] Preferably, at least part of the collecting basket is embedded in the precipitation box from top to bottom in the vertical direction. The first filter screen is arranged at the bottom of the collecting basket, and the first filter screen is also arranged on the side wall of the collecting basket.

[0014] Preferably, the cutting chip discharging device further includes a power pump and a circulation pipeline. The input end of the power pump communicates with the storage box, the circulation pipeline communicates with the output end of the power pump and the cutting component, and the power pump is used for conveying the wet chips in the storage box to the cutting component through the circulation pipeline.

[0015] Preferably, a third filter screen is arranged at the input end of the power pump.

[0016] Preferably, the cutting chip discharging device further includes a reflux pipeline. The reflux pipeline extends in a U shape. One end of the reflux pipeline communicates with the storage box, and the other end communicates with the circulation pipeline. The reflux pipeline is configured with a first solenoid valve, and the first solenoid valve is used for controlling the reflux pipeline to be communicated or disconnected.

[0017] Preferably, the cutting chip discharging device further includes a spraying component. The spraying component is arranged in the processing chamber, and the spraying component can spray liquid into the processing chamber.

[0019] Advantages of the present invention:

[0020] For the cutting and chip removal device proposed by the present invention, the guiding pipe is communicated with the processing chamber through the chip removal port. The first discharge end and the second discharge end of the guiding pipe respectively correspond to the discharge paths of dry chips and wet chips, so that dry chips and wet chips can flow out from different discharge ends respectively. There is no need to set up independent dry and wet chip removal pipelines, reducing the space occupation and the number of components inside the processing chamber, lowering the manufacturing cost and the maintenance complexity, and at the same time ensuring the coherence and reliability of the chip removal function during different process switches. In the dry cutting process, the adsorption component is directly communicated with the first discharge end, and by sucking the dry chips out of the processing chamber through the first discharge end, the dry chips in the processing chamber can be effectively removed. For the wet chips generated in the wet cutting process, the second discharge end forms a communication path with the storage box through the filtering structure. During the flow of the wet chips, through the screening action of the filtering structure, the granular debris and viscous substances therein are intercepted by the filtering structure, while the filtered cutting fluid enters the storage box. This design effectively intercepts the impurities that are likely to block the pipeline through the filtering structure on the one hand, preventing abnormal shutdown of the machine tool components due to poor chip removal; on the other hand, it realizes the preliminary separation of the cutting fluid and the debris, facilitating the subsequent recovery or treatment of the cutting fluid.

[0036] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific implementation manners.

[0037] Embodiment 1

[0038] See Figures 1 to 4, an embodiment of the present invention provides a cutting chip removal device, which is applied to a cutting machine. The cutting machine includes a main body 100. The inside of the main body 100 has a processing chamber 101. A cutting assembly 104 is arranged in the processing chamber 101. A chip removal port 102 is opened on the processing chamber 101. Dry chips or wet chips generated during the cutting process by the cutting assembly 104 will be discharged from the chip removal port 102. The cutting chip removal device is used to divert and discharge the dry chips or wet chips from the chip removal port 102.

[0039] Specifically, the cutting chip removal device includes a guiding pipe 1, an adsorption assembly 2, and a filtering assembly 3. The guiding pipe 1 is communicated with the chip removal port 102. The guiding pipe 1 has a first discharge end 11 that allows dry chips to pass through and a second discharge end 12 that allows wet chips to pass through; the adsorption assembly 2 is communicated with the first discharge end 11 and is used to suck out the dry chips through the first discharge end 11; the filtering assembly 3 includes a storage box 31 and a filtering structure 32. The storage box 31 and the second discharge end 12 are communicated through the filtering structure 32. The wet chips flow out from the second discharge end 12 and enter the storage box 31 after being filtered by the filtering structure 32.

[0040] In the cutting chip removal device proposed by the present invention, the guiding pipe 1 is communicated with the processing chamber 101 through the chip removal port 102. The first discharge end 11 and the second discharge end 12 of the guiding pipe 1 respectively correspond to the discharge paths of dry chips and wet chips, so that dry chips and wet chips can flow out from different discharge ends respectively. There is no need to set up independent dry and wet chip removal pipelines, reducing the space occupation and the number of components inside the processing chamber 101, lowering the manufacturing cost and the maintenance complexity, and at the same time ensuring the coherence and reliability of the chip removal function during different process switches. In the dry cutting process, the adsorption assembly 2 is directly communicated with the first discharge end 11, and the dry chips can be effectively sucked out of the processing chamber 101 through the first discharge end 11. In the wet cutting process, the second discharge end 12 forms a communication path with the storage box 31 through the filtering structure 32. During the flowing process of the wet chips, through the screening effect of the filtering structure 32, the granular debris and viscous substances therein are intercepted by the filtering structure 32, while the filtered cutting fluid enters the storage box 31. This design effectively intercepts the impurities that are easy to block the pipeline through the filtering structure 32 on the one hand, preventing abnormal shutdown of the machine tool components due to poor chip removal; on the other hand, it realizes the preliminary separation of the cutting fluid and the debris, facilitating the subsequent recovery or treatment of the cutting fluid.

[0041] The following elaborates on the specific structure and working principle of the cutting chip removal device.

[0042] During the cutting process, the dry chips and wet chips generated are discharged from the chip discharge port 102 of the processing bin 101. A hopper 103 communicating with the guiding pipe 1 is provided at the chip discharge port 102, and the inner wall of the hopper 103 inclines inward from top to bottom to form a guiding inclined surface. When the dry chips or wet chips come out of the chip discharge port 102, they will slide down along the guiding inclined surface. The inclination angle of the guiding inclined surface enables the dry chips or wet chips to naturally concentrate towards the bottom of the hopper 103 under the action of gravity, and finally smoothly enter the guiding pipe 1, realizing a smooth transition from the chip discharge port 102 of the processing bin 101 to the guiding pipe 1. The setting of the hopper 103 increases the butt-joint area between the chip discharge port 102 and the guiding pipe 1, improves the chip discharge efficiency, and reduces the possibility of chips accumulating near the chip discharge port 102. The guiding inclined surface uses gravity to guide the flow of the chips, without the need for additional power devices, saving energy and having a simple and reliable structure.

[0043] The guiding pipe 1 is arranged at the bottom of the hopper 103 and communicates with the hopper 103. The guiding pipe 1 extends in the vertical direction, and a second discharge end 12 is provided at the bottom of the guiding pipe 1. The second discharge end 12 is configured with a waterway one-way valve 13, and the waterway one-way valve 13 is connected to a filtering structure 32; a first discharge end 11 is provided on the side wall of the guiding pipe 1, and the first discharge end 11 is configured with a bridge-shaped elbow 14. The middle part of the bridge-shaped elbow 14 bulges upward and bends and extends, and the bridge-shaped elbow 14 communicates with the adsorption assembly 2.

[0044] During the cutting operation, when wet cutting is performed, due to the relatively large self-weight of the wet chips, they can flow downward along the axial direction of the guiding pipe 1 under the action of gravity to the second discharge end 12 at the bottom of the guiding pipe 1, and flush open the waterway one-way valve 13, and thus flow along the second discharge end 12 at the bottom of the guiding pipe 1 to the filtering structure 32. When dry cutting is performed, since the dry chips are light in texture and small in weight, they cannot generate enough pressure to flush open the waterway one-way valve 13. At this time, the waterway one-way valve 13 remains in a closed state, and the dry chips are completely blocked inside the guiding pipe 1. The waterway one-way valve 13 can effectively achieve the gravity separation effect for dry chips and wet chips, without the need for additional control intervention, which can not only ensure the smooth passage of wet chips, but also effectively block dry chips, so as to ensure the diversion of dry chips and wet chips and avoid cross-contamination.

[0045] At the same time, the first discharge end 11 is arranged on the side wall of the guiding pipe 1 and communicates with the adsorption assembly 2 through the bridge-shaped elbow 14. Since when dry cutting is performed, the dry chips have a relatively small density and do not have enough force to push open the waterway one-way valve 13. And when the adsorption assembly 2 starts to adsorb, the suction force generated by it will act together with the valve spring force of the waterway one-way valve 13 to make the waterway one-way valve 13 close more tightly, and then make the second discharge end 12 in a closed state to prevent dry chips from entering. At this time, the suction force generated by the adsorption assembly 2 can suck away the dry chips through the first discharge end 11 and the bridge-shaped elbow 14.

[0046] The bent structure with an upward bulge in the middle of the bridge-shaped elbow 14 forms a physical barrier for air flow. Due to its own weight, the wet chips cannot enter the bridge-shaped elbow 14, thus completely isolating the dry and wet chip discharge paths spatially. This design not only realizes the automatic separation of dry and wet chips by utilizing the gravity and aerodynamic characteristics, but also avoids the mixing or cross-contamination of dry and wet chips during the chip discharge process through the coordinated action of the waterway one-way valve 13 and the bridge-shaped elbow 14, ensuring that the adsorption component 2 only processes dry chips and the filtering component 3 only separates wet chips.

[0047] In other embodiments, the first discharge end 11 and the second discharge end 12 can achieve efficient separation of dry and wet chip discharge through different structural designs. For example, the first discharge end 11 can be arranged in the top area of the guiding tube 1 and configured with an inclined deflector plate, and an arc-shaped flow channel extending towards the adsorption component 2 is formed on the surface of the deflector plate. During dry cutting, the negative pressure air flow generated by the adsorption component 2 drives the dry chips to be conveyed upward along the arc-shaped path of the deflector plate, while the wet chips naturally sink to the second discharge end 12 at the bottom of the guiding tube 1 due to their own fluidity and gravity, thus achieving the preliminary separation of dry and wet materials. The second discharge end 12 can be further designed as a funnel-shaped contraction structure, and an elastic sealing diaphragm that can be opened and closed is arranged at the end. When the wet chips accumulate to a certain amount, their weight presses the diaphragm to open, and the wet chips flow into the filtering component 3; after emptying, the diaphragm automatically resets and closes to prevent the evaporation of cutting fluid or the backflow of external impurities.

[0048] Or, in another implementation, the first discharge end 11 can be integrated with a cyclone separation chamber, and spiral guide vanes are arranged inside the chamber. When the adsorption component 2 is started, the air flow containing dry chips forms a centrifugal force after entering the cyclone separation chamber under the action of the guide vanes. The dry chips are thrown towards the outer wall of the chamber and discharged along the tangential direction, while the wet chips cannot rotate with the air flow due to their larger density and directly settle axially to the second discharge end 12. A mesh interception grille can be added to the second discharge end 12, and the pore size of the grille is adapted to the interception requirements of impurities in the wet chips. It can not only allow the cutting fluid and fine particles to pass through, but also block large particles or agglomerated substances from entering the storage box 31 to avoid excessive load on the filtering structure 32.

[0049] Exemplarily, the adsorption component 2 includes a guiding tube 21, a vacuum cleaner 22, and a dust collection box. One end of the guiding tube 21 is connected to the bridge-shaped elbow 14, and the other end is connected to the vacuum cleaner 22. The vacuum cleaner 22 can form a negative pressure environment inside the guiding tube 21. A dust suction motor is provided inside the vacuum cleaner 22, and a strong suction force is generated by the high-speed rotation of the motor. The dry chips are sucked from the first discharge end 11 of the guiding tube 1, enter the guiding tube 21 through the bridge-shaped elbow 14, and are conveyed along the guiding tube 21 to the inside of the vacuum cleaner 22. When the dry chips are sucked into the vacuum cleaner 22, under the action of the filtering and separation mechanism inside the vacuum cleaner 22, the dry chips are collected in the dust collection box. The dust collection box adopts a detachable design, which is convenient for regularly cleaning the collected dry chips to ensure the continuous and stable operation of the adsorption component 2.

[0050] The filtering structure 32 is used to filter the wet chips from the second discharge end 12 and convey them into the storage box 31. Specifically, the filtering structure 32 includes a collection basket 321 and a first filter screen 322. The collection basket 321 is connected to the second discharge end 12, and the first filter screen 322 is arranged on the collection basket 321. The collection basket 321 is connected to the storage box 31 through the first filter screen 322.

[0051] After the wet chips enter the collection basket 321 from the second discharge end 12, they first come into contact with the first filter screen 322. The first filter screen 322 preliminarily intercepts large particle debris and viscous substances in the wet chips through the size of its mesh holes, while the cutting fluid and fine particles pass through the first filter screen 322 and flow into the storage box 31. The collection basket 321 serves as a temporary storage container for the wet chips, capable of centrally accommodating the intercepted solid impurities and preventing them from directly contacting the internal structure of the storage box 31. The operator can regularly take out the entire collection basket 321 for cleaning without disassembling the entire filtering assembly 3 or shutting down the machine, simplifying the maintenance process. The integrated design of the first filter screen 322 and the collection basket 321 not only ensures the continuity of wet chip filtering but also reduces the risk of filter screen blockage through physical isolation. After passing through the first filter screen 322, the purity of the wet chips entering the storage box 31 is initially guaranteed, which is beneficial for subsequent recycling or reuse.

[0052] Further, the storage box 31 is horizontally divided into a sedimentation box 311 and a liquid collection box 312 that are interconnected. The sedimentation box 311 and the liquid collection box 312 are interconnected through a second filter screen 313. The collection basket 321 is detachably connected to the sedimentation box 311 and is connected to the sedimentation box 311 through the first filter screen 322.

[0053] After the wet chips are preliminarily filtered by the first filter screen 322 of the collection basket 321, the cutting fluid carrying fine particles enters the sedimentation box 311. Since the sedimentation box 311 extends horizontally and is connected to the liquid collection box 312, the flow rate of the cutting fluid decreases when flowing in the sedimentation box 311, causing the remaining fine particles to naturally settle at the bottom of the sedimentation box 311 under the action of gravity, while the relatively clarified liquid enters the liquid collection box 312 through the second filter screen 313. The aperture of the second filter screen 313 is smaller than that of the first filter screen 322, which can secondarily intercept fine impurities in the cutting fluid, thereby further improving the cleanliness of the cutting fluid. The detachable connection design of the collection basket 321 and the sedimentation box 311 facilitates the operator to separately take out the collection basket 321 to clean the intercepted large particle impurities, improving the convenience of the device.

[0054] Optionally, at least a part of the collection basket 321 is vertically embedded in the sedimentation box 311 from top to bottom. The first filter screen 322 is arranged at the bottom of the collection basket 321, and the first filter screen 322 is arranged on the side wall of the collection basket 321.

[0055] When a large amount of wet chips are generated in the wet cutting process, the bottom of the collection basket 321 may be completely covered by the accumulated impurities. If only relying on the first filter screen 322 at the bottom, the wet chips will be difficult to discharge due to the blocked penetration path at the bottom, and may even overflow from the upper edge of the collection basket 321 due to the backlog of wet chips. By adding a first filter screen 322 to the side wall of the collection basket 321, after the wet chips enter the collection basket 321, they can seep out through multiple paths, namely the first filter screen 322 in the vertical direction at the bottom of the collection basket 321 and the first filter screen 322 in the horizontal direction on the side wall of the collection basket 321, increasing the effective filtration area. Even if the first filter screen 322 at the bottom of the collection basket 321 is covered by large particle impurities, the first filter screen 322 on the side wall of the collection basket 321 can still provide redundant seepage channels, avoiding liquid backflow or abnormal increase in liquid level, and ensuring that the cutting fluid continuously and stably flows to the sedimentation tank 311.

[0056] The chip and cutting fluid discharging device further includes a power pump 4 and a circulation pipeline 41. The input end of the power pump 4 is communicated with the storage tank 31, and the circulation pipeline 41 is communicated with the output end of the power pump 4 and the cutting assembly 104. The power pump 4 is used to transport the wet chips in the storage tank 31 to the cutting assembly 104 through the circulation pipeline 41.

[0057] Since the wet chips collected in the storage tank 31 have been gradually filtered through the collection basket 321, the sedimentation tank 311 and the liquid collection tank 312, most of the solid impurities have been removed, and their cleanliness and lubrication performance have been restored, forming a relatively clean cutting fluid. The power pump 4 transports the wet chips in the storage tank 31 to the cutting assembly 104 through the circulation pipeline 41. The recycled cutting fluid participates in the wet cutting process again at the cutting assembly 104, reducing the external discharge demand of the cutting fluid and the resource consumption and waste liquid treatment cost. The circulation pipeline 41 continuously supplies the purified cutting fluid, which can maintain the temperature and concentration stability of the cutting fluid during the processing, enhancing the economy and environmental friendliness of the chip and cutting fluid discharging device.

[0058] Optionally, a third filter screen is provided at the input end of the power pump 4. By adding the third filter screen, the operation safety of the power pump 4 and the quality of the recycled cutting fluid are further ensured. The third filter screen is arranged at the input end of the power pump 4 to perform fine filtration at the end of the cutting fluid suctioned from the storage tank 31. Even if there is a small amount of impurity escape in the pre-stage filtration of the collection basket 321 and the sedimentation tank 311, the third filter screen can still effectively intercept the remaining tiny particles or fibrous substances, preventing them from entering the interior of the power pump 4 and causing impeller wear, flow channel blockage or seal failure. The cutting fluid purified by the third filter screen has a higher purity, and can fully exert its lubrication and cooling effects when circulated to the cutting assembly 104, reducing the abnormal wear on the surfaces of the tool and the workpiece, and ensuring the long-term stability of the machining accuracy.

[0059] It should be noted that the above-mentioned first filter screen 322, second filter screen 313 and third filter screen all adopt a detachable connection structure, which is convenient for later maintenance and replacement. The specific implementation form of each filter screen can be flexibly designed. For example, through holes can be opened on the filter plate or other equivalent structures can be used. This embodiment does not limit this.

[0060] In particular, from the first filter screen 322 to the third filter screen, the aperture of the filter holes is designed to decrease step by step. The first filter screen 322 has a larger aperture and is mainly used to intercept large particle impurities in the wet chips; the second filter screen 313 has a moderate aperture and is responsible for intercepting the fine particles settled in the sedimentation tank 311; the third filter screen has the smallest aperture to form a further refined filtration to ensure that the cutting fluid entering the power pump 4 meets the high cleanliness requirements. Through the gradient configuration of the filter hole apertures, pollutants with different particle sizes can be intercepted step by step, which not only avoids excessive load on a single filter screen, but also improves the overall filtration accuracy through multi-level cascade filtration. At the same time, the detachable design enables maintenance personnel to quickly complete the disassembly, cleaning or replacement operations according to the actual blockage conditions of each filter screen without disassembling the main structure of the equipment.

[0061] In order to prevent the cutting fluid remaining in the circulation pipeline 41 from contaminating the zirconia disc during dry cutting, the chip removal device for cutting also includes a return pipeline 5. The return pipeline 5 extends in a U shape. One end of the return pipe is connected to the storage tank 31, and the other end is connected to the circulation pipeline 41. The return pipeline 5 is provided with a first solenoid valve 51, and the first solenoid valve 51 is used to control the connection or disconnection of the return pipeline 5.

[0062] When the wet cutting process ends and switches to the dry cutting process, the power pump 4 stops running, and the first solenoid valve 51 is synchronously opened. At this time, both ends of the U-shaped return pipeline 5 are connected to the storage tank 31 and the circulation pipeline 41 respectively. The cutting fluid remaining in the circulation pipeline 41 flows towards the storage tank 31 along the low point of the return pipeline 5 under the action of gravity. Since the high point of the return pipeline 5 is lower than the installation position of the cutting assembly 104, the cutting fluid quickly returns to the storage tank 31 under the assistance of the siphon effect, thereby completely emptying the residual liquid in the section of the circulation pipeline 41 from the first solenoid valve 51 to the cutting assembly 104 and preventing it from dripping into the processing chamber 101 to contaminate dry cutting process components such as the zirconia disc.

[0063] Furthermore, the chip removal device for cutting also includes an air supply source 6 and an auxiliary pipeline 61. The auxiliary pipeline 61 is used to connect the output end of the air supply source 6 and the circulation pipeline 41. The auxiliary pipeline 61 is provided with a second solenoid valve 62, and the first solenoid valve 51 is used to control the connection or disconnection of the auxiliary pipeline 61.

[0064] When the device switches from the wet cutting mode to the dry cutting mode, the power pump 4 stops running, and the first solenoid valve 51 opens to allow most of the cutting fluid in the circulation pipeline 41 to flow back to the storage tank 31 by gravity through the return pipeline 5. If there is liquid retention in the circulation pipeline 41 due to complex structure or local high points, the second solenoid valve 62 opens synchronously, and the compressed gas output by the gas supply source 6 is injected into the circulation pipeline 41 through the auxiliary pipeline 61. The high-pressure gas pushes the residual liquid to flow along the pipeline towards the direction of the return pipeline 5. Especially for the pipeline dead ends in the section from the second solenoid valve 62 to the cutting component 104, the residual liquid is completely discharged by the air flow scouring, avoiding scale formation or dripping pollution of the zirconia disk in the processing chamber 101 after drying. Through the coordinated action of the return pipeline 5 and the auxiliary pipeline 61, the operator can complete the pipeline purification without manual intervention. The auxiliary pipeline 61 serves as a backup evacuation path to provide additional guarantee and further improve the reliability of the wet-dry mode switch.

[0065] The chip removal device further includes a spraying component 7. The spraying component 7 is arranged in the processing chamber 101. The spraying component 7 can spray liquid into the processing chamber 101. By spraying with the spraying component 7, each part such as the inner wall of the processing chamber 101 and the cutting component 104 is flushed, and the residual dry chips and wet chips are washed down, so that they flow out along the chip removal channel, keeping the processing chamber 101 clean and preparing for the next processing.

[0066] It can be understood that the spraying component 7 is a mechanical device related to this field. Regarding the working principle and specific structure, no further description will be given here.

[0067] In addition, inside the main body 100 of the cutting machine and the processing chamber 101, due to the complexity of the cutting operation, some fine dry chips or sticky wet chips may adhere to difficult-to-clean parts such as the gaps of the cutting component 104 and the corners of the processing chamber 101. Therefore, the chip removal device further includes a water gun and an air gun. The water gun adopts an adjustable design, and its nozzle can adjust the spraying angle and strength of the water flow by rotating or pressing a button. The water gun is connected to an independent cleaning water source, and the water source is transported to the nozzle of the water gun through a pipeline.

[0068] When cleaning is required, the operator can hold a water gun, aim the nozzle at the hard-to-clean corners, and by adjusting the water flow parameters, use the impact force of the high-pressure water flow to wash off the attached wet chips. The washed wet chips flow along the preset diversion structure in the processing chamber 101 towards the chip discharge port 102, and then enter the filtering assembly 3 through the second discharge end 12 of the guiding pipe 1. The air gun also adopts a handheld design for easy operation and is internally connected to a compressed air source. The nozzle of the air gun can eject compressed air to a specific position. When the operator operates the air gun, the compressed air sprays out at high speed from the nozzle, forming a strong air flow that blows off the dry chips attached to the hard-to-clean corners. Under the action of the air flow, the dry chips fall into the chip discharge port 102 at the bottom of the processing chamber 101 and are discharged, and then are adsorbed by the adsorption assembly 2 through the first discharge end 11. With the equipped water gun and air gun, the operator can perform manual minor treatment on the hard-to-clean corners in the chip cutting and discharging device, further improving the convenience and thoroughness of cleaning and ensuring that the inside of the processing chamber 101 remains clean.

[0069] It can be understood that electrical devices such as the power pump 4, the first solenoid valve 51, the second solenoid valve 62, and the adsorption assembly 2 in this application are centrally controlled through a programmable logic controller PLC. It should be noted that the control logic and implementation methods of the PLC for each electrical device belong to conventional technical means in this field. For example, specific control strategies such as adjusting the device operation timing through sensor signal feedback and setting fault protection thresholds are all implemented using existing mature solutions. The innovation point of this application lies in the physical structure design and functional coordination relationship of the chip cutting and discharging device, rather than the programming method of the control system itself. Therefore, for control details such as the hardware selection, program writing, and communication protocol of the PLC, those skilled in the art can adapt using well-known technologies according to actual needs and will not be elaborated here.

[0070] Embodiment 2

[0071] The embodiment of the present invention also provides a cutting machine, which includes a main body 100. The main body 100 of the cutting machine is configured with the chip cutting and discharging device provided in Embodiment 1. The main body 100 of the cutting machine and the discharging device form an integrated layout. Dry chips or wet chips generated in the processing chamber 101 can directly enter the diversion system of the guiding pipe 1 through the chip discharge port 102, without the need to additionally set up an external chip discharge channel, greatly improving the space utilization rate of the device. In the dry cutting mode, the adsorption assembly 2 and the first discharge end 11 cooperate to timely remove the flying dry chips in the processing chamber 101. In the wet cutting mode, the second discharge end 12 is used to effectively discharge the wet chips, and through the multi-stage separation design of the filtering assembly 3, the wet chips can always maintain a high cleanliness during the circulation process. The cooperation between the chip cutting and discharging device and the main body 100 simplifies the internal pipeline layout of the device and reduces the risk of failures caused by pipeline crossing or redundant connections.
