Description
Technical Field
[0001] This utility model relates to the technical field of CNC lathe waste chip treatment equipment, specifically to a CNC lathe waste chip screening and treatment device. Background Technology
[0002] During CNC lathe machining, a large amount of waste chips are generated. These chips vary in size and shape, and if not effectively treated, they will not only pollute the working environment but also affect subsequent machining operations and resource recycling. For example, accumulated chips may hinder the normal operation of the machine tool, and chips mixed in with the cutting fluid will affect the performance of the cutting fluid. At the same time, the mixing of chips of different particle sizes makes subsequent sorting and recycling extremely difficult.
[0003] Currently, several technical solutions exist for handling CNC lathe waste chips on the market. For example, patent application CN202322094781 discloses a multi-stage screening and processing device for CNC machine tool waste chips. This device, through its housing and internal filtration and screening devices, can filter out liquid waste such as cutting fluid and separate ferrous waste chips. However, this device is not fine enough in its screening of waste chip particle size, and cannot classify the waste chips according to different diameters. Another example is patent application CN201911314220, which, while able to separate metal fragments and powders, lacks an efficient vibration screening mechanism during the screening process, resulting in low screening efficiency and failing to meet the needs of rapid waste chip processing in large-scale production. Patent application CN202421485232, entitled "A CNC Lathe Waste Chip Separation Device," mainly focuses on dividing the waste chip loading area into multiple cavities to separate different types of waste chips and coolant; however, it is insufficient in its ability to screen the waste chips themselves according to particle size.
[0004] In summary, existing CNC lathe waste chip processing devices have certain shortcomings in terms of the fineness and efficiency of waste chip screening. There is an urgent need for a device that can efficiently and accurately screen CNC lathe waste chips, classify them according to different diameters and discharge them, and has a good collection function, in order to solve the problems existing in the current technology. Utility Model Content
[0005] The purpose of this utility model is to provide a CNC lathe waste chip screening and processing device to solve the problems mentioned in the background art regarding the deficiencies of existing CNC lathe waste chip processing devices in terms of the fineness and efficiency of waste chip screening.
[0006] To achieve the above objectives, this utility model provides a CNC lathe waste screening and processing device, including a screening chamber. The screening chamber is equipped with a vibrating frame for vibrating and screening materials. The vibrating frame is equipped with an upper screen, a slide, and a lower screen from top to bottom, which separates the materials into three different diameters and discharges them separately. The bottom of the vibrating frame is equipped with a fine material collection chamber for collecting fine materials. The vibrating frame is driven by a vibrating motor to vibrate, and a spring is installed at the bottom of the vibrating frame.
[0007] This setup features a vibrating frame inside the screening chamber, driven by a vibration motor. Springs at the bottom of the frame act as buffers and assist in vibration, ensuring continuous and stable vibration. Waste enters from above, passing sequentially through the upper screen, chute, and lower screen. Utilizing the differences in screen aperture sizes, the waste is graded and screened according to its diameter, with the finest material falling into the fine material collection bin.
[0008] Preferably, a handle is installed on the upper part of one side of the screening chamber, a support leg is installed at the bottom of the screening chamber, and a roller is installed at the bottom end of the support leg.
[0009] This device features a handle on the upper side of the screening chamber to provide a leverage point for the operator, and rollers at the bottom of the support feet reduce the friction between the device and the ground. The operator moves the device by pushing the handle and using the rolling of the rollers.
[0010] Preferably, the top of the screening chamber is provided with a funnel-shaped collection port, the upper screen is inclined and located below the collection port, and a coarse material channel is provided on the outer side of one end of the upper screen.
[0011] The funnel-shaped collection port at the top of the screening chamber guides the waste material smoothly into the screening chamber. The inclined upper screen causes the waste material to move along the screen to one end under its own weight and the vibration of the vibrating frame. Coarse material with a diameter larger than the screen holes of the upper screen cannot pass through the screen and is finally discharged from the coarse material channel on the outside of one end of the upper screen.
[0012] Preferably, the bottom of the coarse material channel is designed with a slope, and a discharge port is provided on one side of the slope, with a first sealing plug installed at the discharge port.
[0013] The inclined design at the bottom of the coarse material channel allows the coarse material to slide automatically towards the discharge port under gravity. The first sealing plug acts as a seal when no material is being discharged, preventing the leakage of waste and dust. When it is necessary to discharge the coarse material, the first sealing plug is opened, and the coarse material can be discharged from the discharge port.
[0014] Preferably, the slide is located at the bottom of the upper screen, and a notch is provided at one end of the slide. The notch is located at the top of the lower screen, and a material channel is provided on the outer side of one end of the lower screen.
[0015] In this setting, the material screened by the upper screen slides down through a chute. A notch at one end of the chute guides the material to the lower screen. Medium material with a diameter smaller than the screen opening of the upper screen but larger than the screen opening of the lower screen cannot pass through the lower screen and is eventually discharged from the medium material channel.
[0016] Preferably, the bottom of the material channel is designed with a slope, and a discharge port is provided on one side of the slope, with a second sealing plug installed at the discharge port.
[0017] This setup is similar to the coarse material channel. The slope at the bottom of the intermediate material channel causes the intermediate material to move towards the discharge port. The second sealing plug controls the opening and closing of the discharge port. When not discharging, the channel is sealed to prevent leakage of intermediate material and dust. When discharging, the second sealing plug is opened, and the intermediate material is discharged smoothly.
[0018] Preferably, the bottom of the screening chamber is provided with an opening, and the top of the fine material collection chamber is detachably installed at the bottom opening of the screening chamber by means of threads.
[0019] This design features an opening at the bottom of the compartment that matches the threaded structure at the top of the fine material collection compartment, allowing for detachable installation of the fine material collection compartment and the screening compartment via a threaded connection. When the fine material collection compartment is full, it can be unscrewed for cleaning or replacement.
[0020] Preferably, a dust collection module is connected to the upper side of the fine material collection chamber. The dust collection module includes an exhaust pipe, a filter chamber is installed in the middle of the exhaust pipe, a filter plate is detachably installed in the filter chamber, and an activated carbon adsorption block is installed in the middle of the filter plate. The air containing dust in the fine material collection chamber is discharged after being adsorbed by the activated carbon adsorption block in the exhaust pipe.
[0021] This system generates dusty air in the fine material collection chamber, which, under the influence of air pressure difference, enters the filter chamber through the exhaust pipe. The filter plate in the filter chamber first intercepts larger dust particles in the air, while the activated carbon adsorption block uses its own adsorption properties to further adsorb tiny particles and harmful gases in the air. The purified air is then discharged from the exhaust pipe.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0023] In this CNC lathe waste chip screening and processing device, a spring is installed at the bottom of the vibrating frame and driven by a vibrating motor, which can generate stable and efficient vibration, so that the waste chips move quickly on the screen and are fully screened. Compared with existing devices that lack efficient vibration screening mechanisms, the screening efficiency is greatly improved, which can meet the needs of rapid waste chip processing in large-scale production.
[0024] The vibrating frame is configured with an upper screen, a slide, and a lower screen from top to bottom, forming a three-stage screening structure. It can separate waste into three categories—coarse, medium, and fine—according to different diameters and discharge them separately. Compared with the problem of insufficient screening in existing devices, it can more accurately classify waste by particle size, which is convenient for subsequent targeted recycling and treatment.
[0025] A handle is installed on the upper side of one side of the screening chamber, and rollers are installed at the bottom of the support feet, which makes it easy for operators to move the screening device and adjust its position, thus improving the flexibility and convenience of the device.
[0026] The bottom of the coarse and medium material channels is designed with a slope and equipped with a discharge port and a sealing plug, so that waste can be discharged smoothly and easy to clean. The fine material collection bin is detachably installed at the bottom opening of the screening bin by a thread, which is convenient for disassembly and cleaning of fine materials. At the same time, this design also makes it easy to replace collection bins of different specifications to meet different collection needs. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] This utility model provides a waste chip screening and processing device for CNC lathes, such as... Figure 1 , Figure 2As shown, the device includes a screening chamber 1, inside which is a vibrating frame 2 for vibrating and screening materials. The vibrating frame 2 is equipped with an upper screen 21, a slide 22, and a lower screen 23 from top to bottom, which divides the materials into three different diameters and discharges them separately. At the bottom of the vibrating frame 2, there is a fine material collection chamber 3 for collecting fine materials. The vibrating frame 2 is driven to vibrate by a vibrating motor 25, and a spring 24 is installed at the bottom of the vibrating frame 2.
[0034] The vibrating frame 2 inside the screening chamber 1 is driven by a vibrating motor 25. The spring 24 at the bottom of the vibrating frame 2 acts as a buffer and assists in vibration, enabling the vibrating frame 2 to generate continuous and stable vibration. Waste enters from above and passes through the upper screen 21, the slide 22, and the lower screen 23 in sequence. By utilizing the difference in screen hole size of different screens, the waste is classified and screened according to its diameter. The finest material falls into the fine material collection chamber 3.
[0035] In this embodiment, as Figure 1 As shown, a handle 12 is installed on the upper part of one side of the screening chamber 1, and a support leg 13 is installed at the bottom of the screening chamber 1, with a roller installed at the bottom of the support leg 13.
[0036] The handle 12 on the upper side of the screening chamber 1 provides a point of leverage for the operator. The rollers at the bottom of the support legs 13 reduce the friction between the device and the ground. The operator moves the device by pushing the handle 12 and using the rolling of the rollers.
[0037] Specifically, such as Figure 1 , Figure 2 As shown, the top of the screening chamber 1 is provided with a funnel-shaped collection port 11, the upper screen 21 is inclined and located below the collection port 11, and a coarse material channel 14 is provided on the outer side of one end of the upper screen 21.
[0038] The funnel-shaped collection port 11 at the top of the screening chamber 1 can guide the waste material into the screening chamber 1 smoothly. The inclined upper screen 21 causes the waste material to move along the screen to one end under its own weight and the vibration of the vibrating frame 2. Coarse material with a diameter larger than the screen hole of the upper screen 21 cannot pass through the screen and is finally discharged from the coarse material channel 14 on the outer side of one end of the upper screen 21.
[0039] Furthermore, such as Figure 2 As shown, the bottom of the coarse material channel 14 is designed with a slope, and a discharge port is provided on one side of the slope. A first sealing plug 141 is installed at the discharge port.
[0040] The inclined design at the bottom of the coarse material channel 14 allows the coarse material to slide automatically toward the discharge port under the action of gravity. The first sealing plug 141 acts as a seal when no material is being discharged, preventing the leakage of waste and dust. When it is necessary to discharge the coarse material, the first sealing plug 141 is opened, and the coarse material can be discharged from the discharge port.
[0041] Furthermore, such as Figure 2 As shown, the slide 22 is located at the bottom of the upper screen 21. One end of the slide 22 is provided with a notch, which is located at the top of the lower screen 23. A material channel 15 is provided on the outer side of one end of the lower screen 23.
[0042] The material screened by the upper screen 21 slides down through the slide 22. The notch at one end of the slide 22 guides the material to the lower screen 23. The medium material with a diameter smaller than the screen hole of the upper screen 21 but larger than the screen hole of the lower screen 23 cannot pass through the lower screen 23 and is eventually discharged from the medium material channel 15.
[0043] Furthermore, such as Figure 2 As shown, the bottom of the material channel 15 is designed with a slope, and a discharge port is provided on one side of the slope. A second sealing plug 151 is installed at the discharge port.
[0044] Similar to the coarse material channel 14, the slope at the bottom of the intermediate material channel 15 causes the intermediate material to move toward the discharge port. The second sealing plug 151 controls the opening and closing of the discharge port. When not discharging, the channel is sealed to prevent leakage of intermediate material and dust. When discharging, the second sealing plug 151 is opened, and the intermediate material is discharged smoothly.
[0045] Furthermore, such as Figure 2 As shown, the bottom of the screening chamber 1 is provided with an opening, and the top of the fine material collection chamber 3 is detachably installed at the bottom opening of the screening chamber 1 by means of threads.
[0046] The opening at the bottom of the screening chamber 1 matches the threaded structure at the top of the fine material collection chamber 3, allowing for detachable installation of the fine material collection chamber 3 and the screening chamber 1 via a threaded connection. When the fine material collection chamber 3 is full, it can be unscrewed for cleaning or replacement.
[0047] Furthermore, such as Figure 1 , Figure 3 As shown, a dust collection module is connected to the upper side of the fine material collection chamber 3. The dust collection module includes an exhaust pipe 31, a filter chamber 32 is installed in the middle of the exhaust pipe 31, a filter plate 33 is detachably installed in the filter chamber 32, and an activated carbon adsorption block 34 is installed in the middle of the filter plate 33. The air containing dust in the fine material collection chamber 3 is discharged after being adsorbed by the activated carbon adsorption block 34 in the exhaust pipe 31.
[0048] The dust-laden air generated in the fine material collection chamber 3 enters the filter chamber 32 through the exhaust pipe 31 under the action of air pressure difference. The filter plate 33 in the filter chamber 32 first intercepts the larger dust particles in the air, and the activated carbon adsorption block 34 uses its own adsorption characteristics to further adsorb the small particles and harmful gases in the air. The purified air is discharged from the exhaust pipe 31.
[0049] In use, the CNC lathe waste chip screening and processing device of this utility model first introduces waste chips generated during CNC lathe machining, which enter the device through the funnel-shaped collection port 11 at the top of the screening chamber 1. The funnel shape of the collection port 11 guides the waste chips to fall smoothly, preventing them from accumulating or spilling at the inlet and improving collection efficiency. After falling, the waste chips reach the inclined upper screen 21. At this time, the vibration motor 25 starts, driving the vibration frame 2 to generate continuous and stable vibration. The spring 24 at the bottom of the vibration frame 2 acts as a buffer and assists the vibration, making the vibration more stable. Under the combined action of its own gravity and vibration, the waste chips move along the upper screen 21 to one end. Due to the limitation of the screen hole size of the upper screen 21, coarse materials with a diameter larger than the screen hole cannot pass through the screen, but slide along the inclined surface of the screen and are finally discharged from the coarse material channel 14 on the outer side of one end of the upper screen 21, completing the preliminary screening and separation of coarse materials.
[0050] After being screened by the upper screen 21, waste particles with a diameter smaller than the screen openings of the upper screen 21 pass through the screen and fall into the slide 22 located at the bottom of the upper screen 21. The slide 22 serves to receive and guide the waste particles to the upper screen 23. The waste particles continue to slide within the slide 22, reaching the lower screen 23 through a notch at one end of the slide 22. Under the same vibration, the waste particles move on the lower screen 23. At this time, medium-sized materials with a diameter smaller than the screen openings of the upper screen 21 but larger than the screen openings of the lower screen 23 cannot pass through the lower screen 23, but slide along the inclined surface of the lower screen 23 and are finally discharged from the medium-sized material channel 15, thus achieving the screening and separation of medium-sized materials.
[0051] After being screened by both the upper screen 21 and the lower screen 23, the smallest diameter fine material passes through the lower screen 23 and falls into the fine material collection bin 3 at the bottom of the vibrating frame 2. The fine material collection bin 3 is detachably installed at the bottom opening of the screening bin 1 by means of threads, which facilitates disassembly, cleaning or replacement after it is full of fine material, so as to ensure the continuity of fine material collection.
[0052] During the fine material collection process, dust-laden air is generated. Under the influence of air pressure difference, this air enters the dust collection module through the exhaust pipe 31 connected to the upper side of the fine material collection chamber 3. First, the air enters the filter chamber 32, where the filter plate 33 intercepts larger dust particles. Next, the air continues to flow, passing through the activated carbon adsorption block 34 in the middle of the filter plate 33. The activated carbon adsorption block 34, utilizing its strong adsorption properties, further adsorbs fine particles and harmful gases from the air. The purified air is finally discharged from the exhaust pipe 31, effectively reducing dust pollution and improving the working environment.
[0053] When the device position needs to be adjusted, the operator can easily move the device to the desired position by holding the handle 12 on the upper side of the screening chamber 1 and using the rollers at the bottom of the support feet 13, thus improving the flexibility of the device. After the coarse and medium materials are collected, the operator can open the first sealing plug 141 at the discharge port of the coarse material channel 14 and the second sealing plug 151 at the discharge port of the medium material channel 15, respectively. Due to the inclined design at the bottom of the coarse material channel 14 and the medium material channel 15, the coarse and medium materials are automatically discharged from the discharge ports, facilitating subsequent cleaning and processing.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
