Description

Technical Field

[0002] During the machining process of a numerical control machine tool, a large amount of metal waste chips will be generated. If these waste chips are not effectively processed, they will not only occupy a large amount of space but also cause environmental pollution.

[0003] Referring to a Chinese patent with the patent name: A Crushing-Type Waste Chip Treatment Device (Application No.: CN202323482905.0, Publication Date: October 1, 2024), which includes a fixed seat located at the bottom of the entire device. A crushing main body is fixedly installed at the upper end of the fixed seat. A panel is installed on the front of the crushing main body. Cylinders are installed on both side parts of the crushing main body. A pneumatic rod is installed at the output end of the cylinder. An extrusion member is fixedly installed on the pneumatic rod. A first crushing roller, a second crushing roller, and a third crushing roller are respectively installed at the upper end of the extrusion member. The waste chip treatment device provided by this device fully crushes the waste chips through the crushing of the three crushing rollers. The inside of the crushing roller is communicated with a hot air blower through a connecting pipe, and the waste chips can be dried during the crushing process to prevent the collection and treatment of wet waste chips from being inconvenient. The crushed waste chips are compacted by the extrusion member, which facilitates the collection of waste chips.

[0004] In the above patent, although the waste chips can be dried, there are still the following problems: When the prior art dries the waste chips, it does not consider the special properties of the cutting oil in the waste chips. Compared with moisture, the cutting oil is difficult to evaporate by heat and has a certain viscosity. This results in a large amount of cutting oil still being doped in the waste chips after drying, thus affecting the purity of the subsequent recycling of the waste chips.

[0005] Therefore, the present invention provides a comprehensive waste chip crushing and treatment system and control method for a numerical control machine tool. Summary of the Invention

[0026] Beneficial effects

[0027] The present invention provides a waste chip crushing comprehensive treatment system and control method for a numerical control machine tool. Compared with the prior art, it has the following beneficial effects:

[0028] 1. For the waste chip crushing comprehensive treatment system and control method of this numerical control machine tool, driven by the driving component, the entire solid-liquid separation component rotates at a high speed. After the waste chips enter the small cylindrical shell, they fall through the channel formed by the spiral guide plate between the conical mesh cover and the inner conical cover. Under the action of centrifugal force, the cutting oil is thrown towards the conical mesh cover and flows out through the mesh holes. At the same time, the waste chips in the channel move from the small end to the large end under the action of centrifugal force and spiral differential speed, so that the waste chips continue to move towards the compaction component below, thereby realizing the separation of cutting oil and waste chips, and improving the purity of subsequent recycling of waste chips.

[0029] 2. For the waste chip crushing comprehensive treatment system and control method of this numerical control machine tool, the cleaning component can introduce high-pressure gas through the air inlet pipe, distribute it to each branch pipe through the annular shell, and then eject the air flow from the air nozzles on the air outlet pipe to perform reverse purging on the conical mesh cover, ensuring that the mesh holes of the conical mesh cover are always unblocked, so that the cutting oil can flow out through the mesh holes smoothly, thereby ensuring the efficient progress of the oil-chip separation process.

[0030] 3. For the waste chip crushing comprehensive treatment system and control method of this numerical control machine tool, the fixed column and the three fixed brackets connect the inner conical cover, the small cylindrical shell and the large cylindrical shell into a whole.

Detailed implementation manners

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1-10 , the present invention provides a technical solution: a waste chip crushing comprehensive treatment system for a numerical control machine tool, including a frame 1, on which a waste chip treatment mechanism is installed. The waste chip treatment mechanism includes:

[0044] The crushing component 2 is installed on the top of the frame 1 and is used for crushing waste chips;

[0045] The solid-liquid separation component 3 is arranged below the crushing component 2 and is used for the oil-chip separation operation. The solid-liquid separation component 3 includes a small cylindrical shell 31. A conical mesh cover 32 is fixedly connected to the bottom of the small cylindrical shell 31. A large cylindrical shell 33 is fixedly connected to the bottom of the conical mesh cover 32. An inner conical cover 34 is arranged inside the conical mesh cover 32. A spiral guide plate 35 is fixedly connected between the conical mesh cover 32 and the inner conical cover 34. A channel capable of accommodating waste chips to pass through is formed between the conical mesh cover 32 and the inner conical cover 34;

[0046] The driving component 4 is arranged outside the solid-liquid separation component 3 and is used for driving the solid-liquid separation component 3 to perform a rotational motion;

[0047] The liquid receiving component 5 is arranged outside the solid-liquid separation component 3 and is used for receiving cutting oil;

[0048] The cleaning component 6 is arranged inside the solid-liquid separation component 3 and is used for removing debris on the conical mesh cover 32;

[0049] The compaction component 7 is arranged below the solid-liquid separation component 3 and is used for receiving and compacting debris.

[0050] Specifically, under the operation of the driving component 4, the entire solid-liquid separation component 3 is driven to rotate at a high speed. After the waste chips enter the small cylindrical shell 31, they fall through the channel formed by the spiral guide plate 35 between the conical mesh cover 32 and the inner conical cover 34. Under the action of centrifugal force, the cutting oil is thrown towards the conical mesh cover 32 and flows out through the mesh holes. At the same time, the waste chips in the channel move from the small end to the large end under the action of centrifugal force and spiral differential speed, so that the waste chips continue to move towards the compaction component 7 below, thereby realizing the separation of cutting oil and waste chips and improving the purity of the subsequent recycling of waste chips.

[0051] Please refer to Figure 2 , the crushing component 2 includes a crushing box 21. Two crushing rollers 22 are arranged inside the crushing box 21. A first motor 23 is installed on one outer wall of the crushing box 21, and the output end of the first motor 23 is axially connected to one of the crushing rollers 22. Two first gears 24 that mesh with each other are installed on the other outer wall of the crushing box 21. The two first gears 24 are respectively axially connected to the two crushing rollers 22. A connection cover 25 is communicated with the bottom of the crushing box 21. The connection cover 25 is movably sleeved on the outer wall of the small cylindrical shell 31. A fixing seat 26 is fixedly sleeved on the outer wall of the connection cover 25. The fixing seat 26 is fixedly installed on the top surface of the frame 1.

[0052] Specifically, after the first motor 23 is started, it drives a crushing rod 22 connected to its axis to rotate two first gears 24 that mesh with each other, which are respectively connected to the axes of the two crushing rods 22, so that the other crushing rod 22 rotates synchronously in the opposite direction. After the waste chips are put into the crushing box 21, they are squeezed, sheared, and rubbed into small particles by the two rotating crushing rods 22. The crushed waste chips enter the small cylindrical shell 31 through the connecting cover 25, and the fixing seat 26 outside the connecting cover 25 is fixed to the top surface of the frame 1 for subsequent processing, thereby playing a supporting and fixing role.

[0053] See also Figures 4-7 The outer wall of the small cylindrical shell 31 is fixedly sleeved with an upper shell 36, and the outer wall of the upper shell 36 near the bottom is fixedly sleeved with an upper contact plate 37, the outer wall of the large cylindrical shell 33 is fixedly sleeved with a lower shell 38, and the outer wall of the lower shell 38 near the top is fixedly sleeved with a lower contact plate 39, and the outer wall of the lower shell 38 near the bottom is penetrated by a plurality of drainage holes 310, and a plane bearing 313 is installed at the bottom of the lower shell 38.

[0054] Specifically, when the solid-liquid separation component 3 rotates driven by the driving component 4 to separate the waste chips from the oil chips, the cutting oil will be thrown from the conical mesh cover 32 into the lower shell 38 under the action of centrifugal force, and flow out through multiple drainage holes 310 to facilitate subsequent collection and processing. The plane bearing 313 can make the entire solid-liquid separation component 3 rotate more smoothly and stably, reduce friction and shaking during rotation, and ensure that the solid-liquid separation work can proceed normally.

[0055] See also Figures 4-6 A fixing column 311 is provided inside the inner conical cover 34, and the fixing column 311 is arranged along the height direction of the inner conical cover 34. The top of the fixing column 311 passes through the top of the inner conical cover 34 and extends upward. Three fixing frames 312 are fixedly connected to the outer wall of the fixing column 311, and the three fixing frames 312 are fixedly connected to the small cylindrical shell 31, the large cylindrical shell 33 and the inner wall of the inner conical cover 34 respectively.

[0056] Specifically, the inner conical cover 34, the small cylindrical shell 31 and the large cylindrical shell 33 are connected into a whole through the fixed column 311 and the three fixed frames 312. In this way, when the solid-liquid separation component 3 rotates under the drive of the driving component 4, the small cylindrical shell 31, the large cylindrical shell 33 and the inner conical cover 34 can maintain a relatively stable positional relationship, thereby improving the stability of the solid-liquid separation component 3.

[0057] See also Figure 3The driving component 4 includes a second motor 41 installed on the top surface of the fixed seat 26. The output shaft end of the second motor 41 movably passes through the top surface of the fixed seat 26 and extends downward. The output shaft end of the second motor 41 is installed with a second gear 42. The driving component 4 includes a ring gear 43 fixedly sleeved on the outer wall of the small cylindrical shell 31, and the ring gear 43 is meshed and connected with the second gear 42.

[0058] Specifically, the power output by the second motor 41 can drive the solid-liquid separation component 3 to rotate through the meshing transmission of the second gear 42 and the ring gear 43 .

[0059] See also Figure 4 The liquid receiving assembly 5 includes a liquid receiving box 51 movably mounted on the outer wall of the large cylindrical shell 33. The inner bottom of the liquid receiving box 51 is fixedly connected to the plane bearing 313. A plurality of legs 52 are fixedly installed at the bottom of the liquid receiving box 51. The bottom of the liquid receiving box 51 is also fixedly connected to a drain pipe 53.

[0060] Specifically, the cutting oil flowing out of the drainage hole 310 will directly fall into the liquid receiving box 51, thereby achieving the receiving of the cutting oil. The cutting oil is discharged through the drainage pipe 53 for subsequent treatment or recycling.

[0061] See also Figure 8 The cleaning component 6 includes an annular shell 61 movably arranged between the upper contact plate 37 and the lower contact plate 39. The interior of the annular shell 61 is a cavity structure. The outer wall of the annular shell 61 is fixedly connected with an air inlet pipe 62. The inner wall of the annular shell 61 is equidistantly fixedly connected with a plurality of branch pipes 63. One end of the branch pipe 63 is fixedly connected with an air outlet pipe 64. The outer wall of the air outlet pipe 64 is provided with a plurality of air nozzles. The plurality of air outlet pipes 64 surround the outer side of the conical mesh cover 32. The outer wall of the annular shell 61 is fixedly installed with a plurality of brackets 65. The brackets 65 are fixedly connected to the inner wall of the liquid receiving box 51.

[0062] Specifically, the cleaning component 6 can introduce high-pressure gas through the air inlet pipe 62, which is distributed to each branch pipe 63 through the annular shell 61, and then the air nozzle on the air outlet pipe 64 sprays the air flow to back-purge the conical mesh cover 32, ensuring that the mesh holes of the conical mesh cover 32 always remain unobstructed, allowing the cutting oil to flow out smoothly through the mesh holes, thereby ensuring the efficient implementation of the oil-chip separation process.

[0063] Furthermore, the top and bottom surfaces of the annular shell 61 are sealedly connected to the upper contact plate 37 and the lower contact plate 39 respectively, which will not affect the normal rotation of the solid-liquid separation component 3.

[0064] See also Figures 9-10, the compaction component 7 includes a compaction box 71. A chip receiving hopper 73 is fixedly communicated with the top of the compaction box 71. The chip receiving hopper 73 surrounds the outer side of the large cylindrical shell 33. A hydraulic rod 72 is fixedly installed on one outer wall of the compaction box 71. The telescopic end of the hydraulic rod 72 slidably penetrates through the outer wall of the compaction box 71 and extends into the interior. A pressing block 74 is installed at the telescopic end of the hydraulic rod 72. The pressing block 74 can slide closely along the inner wall of the compaction box 71. On the other outer wall of the compaction box 71, a fixing plate 75 is installed. A gate plate 76 is slidably arranged inside the fixing plate 75. An electric push rod 77 is installed on the top of the fixing plate 75. The telescopic end of the electric push rod 77 is fixedly connected to the top surface of the gate plate 76.

[0065] Specifically, after being processed by the solid-liquid separation component 3, the chips separated from the cutting oil will fall from the large cylindrical shell 33 and fall into the compaction box 71 along the chip receiving hopper 73, completing the collection process of the chips. When it is necessary to compact the chips falling into the compaction box 71, the hydraulic rod 72 is started, and the pressing block 74 is pushed to move towards the other side inside the compaction box 71. During this process, the pressing block 74 will apply pressure to the chips in the box, compacting the loose chips and reducing their volume. When the chips are compacted, when it is necessary to discharge the compacted block-shaped chips from the compaction box 71, the electric push rod 77 is started, and its telescopic end contracts, driving the gate plate 76 to slide upward inside the fixing plate 75, thereby opening the outlet of the compaction box 71. At this time, the hydraulic rod 72 continues to push the pressing block 74 forward, pushing the compacted block-shaped chips out of the opened outlet from the compaction box 71, completing the entire compaction and discharging process.

[0066] Please refer to Figures 1-10 , the present invention also discloses a control method for a waste chip crushing comprehensive treatment system of a numerical control machine tool, specifically including the following steps:

[0067] S1. The waste chips containing cutting oil first enter the crushing box 21 in the crushing component 2, and then a crushing rod 22 is driven to rotate by a first motor 23. Two mutually meshing first gears 24 drive another crushing rod 22 to rotate synchronously and in the opposite direction to crush the waste chips. The crushed waste chips enter the solid-liquid separation component 3;

[0068] S2. Under the operation of the driving component 4, the entire solid-liquid separation component 3 is driven to rotate at a high speed. After the waste chips enter the small cylindrical shell 31, they fall through the channel formed by the spiral guide plate 35 between the conical mesh cover 32 and the inner conical cover 34. Under the action of centrifugal force, the cutting oil is thrown towards the conical mesh cover 32 and flows out through the mesh holes. At the same time, the waste chips in the channel move from the small end to the large end under the action of centrifugal force and spiral differential speed, so that the waste chips continue to move downward to the compaction component 7;

[0069] S3. The waste chips separated from solid and liquid fall into the chip receiving hopper 73 of the compaction assembly 7, enter the compaction box 71, and the hydraulic rod 72 pushes the pressing block 74 to compact the waste chips. When it is necessary to discharge the compacted waste chips, the electric push rod 77 pulls the gate plate 76 to open and discharge the compacted waste chips.
