Description

Technical Field

[0001] The invention relates to the technical field of metal cutting processing devices, and in particular to a chip conveyor. Background Art

[0002] At present, chip conveyors are indispensable auxiliary devices in metal processing equipment. Their main function is to collect and discharge metal chips, coolants and other waste generated during the processing. In modern metal cutting equipment such as CNC machine tools and machining centers, chip conveyors play a key role in ensuring the cleanliness of the processing area and preventing chips from interfering with or damaging the processing process and machine tools. They are of great significance for maintaining the normal operation of equipment, extending the life of machine tools, improving production efficiency and ensuring the safety and hygiene of the working environment. The working principle of chip conveyors is usually based on conveyor belts, scrapers, spirals, etc., and the chips are transported from the processing area to the designated collection area through mechanical force for subsequent processing. In modern workshops with increasing automation, chip conveyors are often integrated with machine tool control systems, which can automatically adjust the chip removal frequency and speed according to the processing status to achieve intelligent management.

[0003] However, the chip conveyors in the prior art still have certain limitations in terms of functional realization, especially in terms of cleaning function. Most chip conveyors only focus on the physical transportation of chips, while ignoring the removal of impurities such as tiny chips, oil stains, coolants, etc. that may remain during the transportation process. This causes the impurities accumulated inside the chip conveyor to gradually increase after long-term operation, which not only affects the chip removal effect, but may also cause equipment failures such as jamming and increased wear, thereby reducing the stability and production efficiency of the machine tool. In addition, the lack of an effective cleaning mechanism also means that the chip conveyor needs to be manually cleaned regularly, which increases maintenance costs and downtime. For modern manufacturing companies that pursue high efficiency and low maintenance, this is a technical problem that needs to be solved urgently. Therefore, the development of a chip conveyor that can not only efficiently remove chips but also has an automatic cleaning function is of great significance to improving the overall performance of metal processing equipment and the production management level of the workshop.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0024] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0025] like Figures 1 to 3As shown, an embodiment of the present invention provides a chip conveyor for separating metal chips from the cutting fluid of a numerically controlled machine tool. The chip conveyor comprises: a chip conveyor body 1, which is provided with a accommodating chamber 11, and has an inlet end 111 and an outlet end 112 connected to the accommodating chamber 11, wherein the inlet end 111 is used to connect with the chip removal port of the numerically controlled machine tool to allow coolant to flow in, and the outlet end 112 is used to discharge metal chips; a conveying component, which is arranged in the accommodating chamber 11 and is located between the inlet end 111 and the outlet end 112 to transport metal chips; a accommodating box 2, which is connected to the accommodating chamber 11 so that the cutting fluid in the accommodating chamber 11 flows into the accommodating box 2; a bubble generator 3, which comprises a liquid inlet pipe 31 and a liquid outlet pipe 32, wherein the liquid inlet pipe 31 is connected to the accommodating chamber 2, and the liquid outlet pipe 32 is connected to the accommodating chamber 11, and the bubble generator 3 is used to inject gas into the cutting fluid flowing therein to generate cutting fluid with bubbles, and inject the cutting fluid with bubbles into the accommodating chamber 11.

[0026] The chip conveyor provided by the embodiment of the present invention effectively solves the problem of poor chip removal effect of the chip conveyor in the prior art through innovative bubble cleaning technology and reasonable structural design.

[0027] In the above embodiment, the chip conveyor body 1 is the basis of the entire system, and its built-in accommodating chamber 11 serves as a temporary accommodation space for metal chips and cutting fluid. The two ends of the cavity are respectively provided with an inlet end 111 and an outlet end 112, which are convenient for the inflow of cutting fluid and the discharge of metal chips. The design of the chip conveyor body 1 needs to ensure the smooth flow of chips and cutting fluid, while providing installation and working space for other components. The design of the inlet end 111 enables it to closely dock with the chip discharge port of the CNC machine tool, so that the metal chips and cutting fluid mixture generated during the machining process of the machine tool can directly flow into the accommodating chamber 11 of the chip conveyor body 1, avoiding the accumulation of chips on the machine tool, and keeping the machine tool clean and operating normally. The outlet end 112 is used to discharge metal chips from the chip conveyor, and is usually connected to a chip collection car 6 or other chip processing device to facilitate the centralized collection and subsequent processing of chips. The use of the chip collection car 6 not only facilitates the transportation of chips, but also improves the cleanliness and work efficiency of the workshop. The conveying component is located in the accommodating chamber 11, and its main task is to transport metal chips from the inlet end 111 to the outlet end 112. According to the design of the chip conveyor body 1, the conveying component may adopt a chain plate chip conveyor, a spiral type or other forms to ensure the stable transportation of chips during the chip removal process and reduce the risk of chips being retained and blocked in the body. The bubble generator 3 is one of the key innovations of the present invention. It generates bubbles by injecting gas into the cutting fluid, and uses the buoyancy and high-frequency oscillation effect of the bubbles to improve the separation efficiency of metal chips and remove oil and impurities on the surface of the chip conveyor body 1. The bubble generator 3 is connected to the accommodating box 2, and the treated cutting fluid is re-injected into the accommodating chamber 11 through the liquid outlet pipe 32 for recycling and enhancing the chip removal capacity. This design significantly improves the cleanliness of the cutting fluid and the chip removal efficiency of the chip conveyor, reduces the adhesion of chips in the accommodating box 2, and makes it easier to clean the accommodating box 2. The accommodating box 2 provides cutting fluid to the bubble generator 3 through the liquid inlet pipe 31. A water pump 21 is provided inside the receiving box 2 for pumping the cutting fluid to the bubble generator 3.

[0028] like Figure 3 As shown, the bubble generator extracts air and mixes it with the cutting fluid to generate bubbles. The chips are adsorbed and adhered to the inner wall of the chip conveyor due to oil pollution. Now, after the bubbles are generated by the bubble cleaning machine, the bubbles burst when they hit the chips, and the micro-nano bubbles burst and become nano bubbles, which generate impact force and take away some of the oil pollution at the same time. The adsorption force of the chips on the inner wall of the chip conveyor will be reduced due to the reduction of oil pollution, and they will be more easily washed away by the cutting fluid and removed.

[0029] Specifically, the chip conveyor body 1 is provided with a plurality of nozzles 4 arranged at intervals, and the liquid outlet pipe 32 includes a plurality of liquid outlet branches 321, and the plurality of liquid outlet branches 321 are connected to the plurality of nozzles 4 in a one-to-one correspondence, and each nozzle 4 is connected to the accommodating chamber 11 to spray cutting fluid into the accommodating chamber 11. The chip conveyor body 1 is the main body of the entire chip removal system, and its structural design has a direct impact on the chip removal effect. In the present invention, the chip conveyor body 1 is provided with a plurality of nozzles 4, and these nozzles 4 are arranged at intervals, and can uniformly spray cutting fluid containing bubbles into the accommodating chamber 11. The design and layout of the nozzles 4 ensure the uniform distribution of cutting fluid and bubbles, increase the contact area between chips and cutting fluid, thereby improving the separation efficiency of chips and the cleaning effect of the chip conveyor body 1. The position of the nozzle 4 needs to take into account the movement trajectory of the chips to ensure that the bubbles can effectively act on the chips, especially the fine chips that are easy to adhere to the surface of the chip conveyor body 1 or difficult to separate. The cutting fluid containing bubbles generated by the bubble generator 3 is transported to the chip conveyor body 1 through the liquid outlet pipe 32. The liquid outlet pipe 32 is further divided into a plurality of liquid outlet branches 321, which are connected to the nozzles 4 on the chip conveyor body 1 in a one-to-one correspondence, ensuring that the bubbles generated by the bubble generator 3 can be accurately delivered to each nozzle 4. This one-to-one connection method ensures uniform distribution of bubbles, avoids differences in chip removal effects caused by uneven bubble distribution, and improves the cleaning effect and chip removal efficiency of the chip conveyor.

[0030] Specifically, the chip conveyor body 1 has an opening 12, which is arranged below the chip discharge port to form an inlet end 111, and the opening 12 is connected to the accommodating chamber 11. A plurality of nozzles 4 are arranged at intervals on both sides of the opening 12, and each nozzle 4 is arranged on the chip conveyor body 1 and close to the opening 12. The chip conveyor body 1 is the main structure of the chip conveyor, and the opening 12 is located on the chip conveyor body 1, and is particularly arranged below a position corresponding to the chip discharge port of the CNC machine tool to form the inlet end 111. This design ensures that the metal chips and cutting fluid mixture generated during the machining process of the machine tool can directly flow into the accommodating chamber 11 inside the chip conveyor body 1. The position of the opening 12 and its docking with the chip discharge port of the CNC machine tool can effectively collect the waste generated during the cutting process, avoid the accumulation of chips in the working area of ​​the machine tool, and maintain the cleanliness and machining efficiency of the machine tool. A plurality of nozzles 4 are arranged at intervals on both sides of the opening 12, and each nozzle 4 is arranged on the chip conveyor body 1 and close to the opening 12. These nozzles 4 are connected to the bubble generator 3 and are used to inject bubbles into the mixture of metal chips and cutting fluid, and utilize the buoyancy and high-frequency oscillation effect of the bubbles to reduce the adhesion of the chips and improve the separation efficiency of the chips. The position design of the nozzles 4 allows the bubbles to be evenly distributed in the cutting fluid, especially in the initial stage when the chips enter the chip conveyor body 1, the fluidity of the chips can be instantly improved by injecting bubbles, and the chips can be prevented from adhering or clogging near the opening 12.

[0031] Specifically, a reflux port is provided on the chip conveyor body 1, and the containing chamber 11 is connected with the containing box 2 through the reflux port, and the reflux port is located on the side wall of the chip conveyor body 1 close to the containing box 2. The recycling of the cutting fluid is taken into consideration in the design of the chip conveyor body 1, and for this purpose, a reflux port is provided on the side wall of the body close to the containing box 2. The function of the reflux port is to return the cutting fluid that has been initially separated and cleaned to the containing box 2 for further processing or direct recycling. This design ensures the efficient use of the cutting fluid, reduces the waste of resources, and also reduces the frequency and cost of replacing the cutting fluid, which makes a significant contribution to improving production efficiency and economic benefits.

[0032] like Figure 2 As shown, specifically, the chip conveyor also includes a filtering structure 5, one end of the filtering structure 5 is connected to the reflux port, and the other end of the filtering structure 5 is connected to the containing box 2. One end of the filtering structure 5 is connected to the reflux port in the chip conveyor body 1. The reflux port is a channel for the cutting fluid to return from the containing chamber 11 of the chip conveyor body 1 to the containing box 2. The function of the filtering structure 5 is to filter the metal chips, impurities and oil stains in the cutting fluid before it flows back to the containing box 2 to prevent these solid substances from circulating into the CNC machine tool again, affecting the cooling effect and the normal operation of the machine tool. The filtering structure may include a filter screen, a filter medium, etc. The specific design needs to ensure that the chips and impurities can be effectively intercepted and separated, while ensuring the smooth flow of the cutting fluid. The other end of the filtering structure 5 is connected to the containing box 2. The containing box 2 is a storage and circulation base for the cutting fluid. By connecting with the filtering structure 5, the cutting fluid that has been preliminarily purified can be received. The cutting fluid that has passed through the filtering structure 5 has had most of the solid contaminants removed before being sent back to the containing box 2, which not only improves the cleanliness of the cutting fluid, but also reduces the cleaning workload of the containing box 2. The cutting fluid in the containing box 2 can be circulated to the CNC machine tool or the bubble generator 3 again through a pumping device such as a water pump to maintain the continuous supply and recycling of the cutting fluid.

[0033] Specifically, the filter structure 5 has a first side wall 51 and a second side wall 52 that are arranged opposite to each other, and a plurality of filter through holes 53 are arranged on the first side wall 51 and the second side wall 52, and the plurality of filter through holes 53 on the first side wall 51 are connected to the reflux port, and the plurality of filter through holes 53 on the second side wall 52 are connected to the receiving box 2. The filter structure 5 is designed to have a structure with a first side wall 51 and a second side wall 52 that are arranged opposite to each other, and a plurality of filter through holes 53 are arranged on both walls. This design can ensure that the cutting fluid can be evenly distributed in various parts of the filtering structure when passing through the filtering structure, and avoids local blockage or reduction of filtering efficiency due to uneven flow of the cutting fluid. The filter through holes 53 on the first side wall 51 are connected to the reflux port on the chip conveyor body 1, and such a layout ensures that the cutting fluid flowing back from the receiving chamber 11 of the chip conveyor body 1 can first be filtered by the first side wall 51 to remove the larger particles and impurities remaining therein. The filter holes 53 on the second side wall 52 are connected to the containing box 2, which ensures that the cutting fluid preliminarily filtered by the first side wall 51 can be further filtered by the second side wall 52 and then flow into the containing box 2. The design of the second side wall 52 may be more sophisticated, used to filter out smaller particles and oil stains in the cutting fluid to ensure the high cleanliness of the cutting fluid. The size and density of the filter holes on the two walls may be different to meet different filtering requirements. The filter holes on the first side wall 51 may be relatively large to remove large particles of impurities, while the filter holes on the second side wall 52 may be smaller to further purify the cutting fluid.

[0034] Specifically, the chip conveyor also includes an oil separator 54, which is arranged in the cavity of the filter structure 5, and is used to separate the oil on the surface of the cutting fluid in the filter structure 5. The oil separator 54 is a key component arranged in the cavity of the filter structure 5, and its function is to further purify the cutting fluid after preliminary filtration by the filter structure 5. In the metal processing process, the cutting fluid may mix with metal chips, additives in the cutting fluid and impurities in the air to produce oil and foam, which will affect the performance of the cutting fluid and the normal operation of the machine tool. The oil separator 54 removes the oil and foam on the surface of the cutting fluid from the liquid by physical separation, adsorption or condensation, thereby improving the cleanliness of the cutting fluid. Compared with other filter components, the oil separator 54 is more focused on separating light pollutants on the surface of the liquid, rather than larger solid particles, so its design and working principle need to match the filter structure 5 to ensure that the surface of the filtered cutting fluid is free of oil, thereby improving the recycling quality of the cutting fluid.

[0035] Specifically, the chip conveyor is provided with a horizontal section 13 and a lifting section 14, the lifting section 14 is inclined relative to the horizontal section 13, the inlet end 111 is provided at one end of the horizontal section 13 away from the lifting section 14, and the outlet end 112 is provided at one end of the lifting section 14 away from the horizontal section 13. The horizontal section 13 of the chip conveyor body 1 is mainly responsible for receiving the cutting fluid and metal chips discharged from the CNC machine tool, and starting the preliminary separation and transportation process. An inlet end 111 is provided at one end of the horizontal section 13, which is where the cutting fluid and chips first enter the chip conveyor. The length and width of the horizontal section 13 need to meet the chip removal requirements during the cutting process, and at the same time, its gentle conveying surface is conducive to the chips moving forward under the push of bubbles, reducing the accumulation and blockage of chips. The lifting section 14 is a part of the chip conveyor body 1 that is connected to the horizontal section 13 and is inclined relative to the horizontal section. Its function is to lift the chips and cutting fluid after preliminary treatment to a higher position for subsequent separation and treatment. The inclination angle of the lifting section 14 needs to be properly designed to ensure the fluidity of the chips and cutting fluid during the lifting process, and to prevent the chips from sliding back to the horizontal section 13 due to gravity. The outlet end 112 is set at the end of the lifting section 14 away from the horizontal section 13. This design allows the chips to be finally separated at the end of the lifting section 14, and the clean cutting fluid returns to the holding box 2 through the reflux port. The transition and connection between the horizontal section 13 and the lifting section 14 need to be smooth and continuous to ensure that the cutting fluid and chips transition smoothly from the horizontal section to the lifting section, and to avoid chip jamming or cutting fluid leakage at the connection. The introduction of bubbles improves the fluidity of the chips in the horizontal section 13, while in the lifting section 14, the buoyancy of the bubbles is more critical, which helps the light chips and impurities move upward with the cutting fluid, thereby achieving better separation at the outlet end 112. This design combines the physical properties of bubbles and realizes different processing requirements for chips and impurities in the cutting fluid at different stages.

[0036] Specifically, the chip conveyor also includes a chip collecting car 6, which is used to collect metal chips falling from the outlet end 112. A plurality of pulleys 7 are provided at the bottom of the chip conveyor and the chip collecting car 6. The chip conveyor and the chip collecting car 6 are movably arranged, and a locking member is provided on the pulley 7. The chip collecting car 6 is arranged below the outlet end 112 of the chip conveyor body 1, and its function is to collect metal chips falling from the outlet end of the chip conveyor body 1. During the cutting process, the metal chips are transported to the outlet end 112 by the chain plate chip conveyor and other components in the chip conveyor body 1, and fall into the chip collecting car 6 by gravity. The design of the chip collecting car 6 needs to consider the capacity, the chip collection efficiency, and the coordination with the outlet end 112 of the chip conveyor body 1. It needs to be able to effectively dock with the outlet end of the chip conveyor body to avoid the chips from being scattered, and the capacity should be large enough to reduce the frequency of cleaning and replacing the chip collecting car. The pulley 7 is arranged at the bottom of the chip conveyor body 1 and the chip collecting car 6, so that both can be easily moved. This design increases the flexibility of the chip conveyor body 1 and the chip collection cart 6 in the workshop, and can more conveniently adjust the position to adapt to different CNC machine layouts or production requirements. The setting of the pulley 7 needs to take into account the weight of the chip conveyor body 1 and the chip collection cart 6 and the flatness of the workshop floor to ensure stability and safety during movement. The locking member is used to fix the position of the chip conveyor body 1 and the chip collection cart 6 when it is not necessary to move them, to prevent the displacement of the equipment due to vibrations in the workshop environment, accidental collisions by workers or other factors, affecting the processing accuracy and workshop safety. The design of the locking member must ensure that the chip conveyor and the chip collection cart can be firmly positioned in the locked state, and can be easily moved in the unlocked state. The combined use of the locking member and the pulley 7 not only improves the flexibility of the chip conveyor body 1 and the chip collection cart 6, but also ensures their stability in the working state, which is crucial for the efficient operation and operational safety of the workshop.

[0037] Specifically, a plurality of water pumps 21 are provided on the holding box 2, and the water pumps 21 are used to transport the cutting fluid in the holding box 2 to the bubble generator 3, and / or a liquid level sensor is provided inside the holding box 2, and / or a pressure sensor is provided on the liquid outlet pipe 32. The holding box 2 is the storage area of ​​the cutting fluid in the whole system, and the cutting fluid stored inside it needs to be regularly circulated to ensure the cleanliness and performance of the cutting fluid. The water pump 21 is located on the holding box 2, and its function is to extract the cutting fluid in the holding box 2 and send it to the bubble generator 3 for further processing, or directly send it back to the machine tool for cooling and lubrication. The continuous operation of the water pump ensures the circulation of the cutting fluid. At the same time, the storage capacity of the holding box 2 must be sufficient to meet the needs of the circulation and standby of the cutting fluid, so as to avoid the shortage of the cutting fluid during the circulation process and affect the normal operation of the system. The liquid level sensor is a key device for monitoring the cutting fluid level in the holding box 2. By real-time monitoring of the storage amount of the cutting fluid, the shortage of the cutting fluid due to excessive use can be avoided. The information of the liquid level sensor is fed back to the control system. When the cutting fluid level is lower than the preset safety value, the control system will sound an alarm to prompt the operator to replenish the cutting fluid in time, or automatically stop the operation of related components to prevent equipment damage or production accidents caused by insufficient cutting fluid. The pressure sensor is installed on the outlet pipe 32 of the bubble generator 3 to monitor the pressure changes of the cutting fluid during the circulation process. The pressure of the cutting fluid is a key factor affecting its cooling and lubrication effects. Too high or too low pressure may affect the normal circulation of the cutting fluid and the working efficiency of the CNC machine tool. Through the monitoring of the pressure sensor, the working state of the water pump 21 can be adjusted in time, or the pipeline can be inspected and maintained to ensure that the pressure of the cutting fluid is stable during the circulation process, thereby ensuring the stable operation of the entire system and the efficient progress of the processing process.

[0038] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0039] Improve chip separation efficiency: By introducing the bubble generator 3 into the accommodating chamber 11 of the chip conveyor body 1, the cutting fluid forms a mixed liquid containing bubbles after being injected with gas. The bubbles in the mixed liquid can generate buoyancy, pushing light metal chips and impurities to the outlet end 112 of the chip conveyor body 1, thereby significantly improving the chip separation efficiency. Compared with the traditional chip conveyor, the chip conveyor designed by the present invention can remove metal chips from the cutting fluid more thoroughly and quickly, reduce the pollution of the cutting fluid, and extend the service life of the cutting fluid.

[0040] Optimize the recycling of cutting fluid: The connection design between the chip conveyor body 1 and the container 2 ensures that the cutting fluid after preliminary separation can smoothly flow back to the container 2 for secondary purification. The bubble generator 3 injects gas into the cutting fluid, and the generated bubbles further clean the cutting fluid during the circulation of the cutting fluid, removing oil stains and tiny impurities. This dual purification mechanism not only improves the recycling rate of the cutting fluid, reduces the consumption and processing cost of the cutting fluid, but also avoids the potential damage to the machine tool by pollutants in the cutting fluid, and improves the stability and processing accuracy of the machine tool.

[0041] Enhanced system stability and safety: The precise coordination between the chip conveyor body 1, the receiving box 2, and the bubble generator 3, as well as the real-time monitoring of the liquid level sensor and the pressure sensor, ensure the stable operation of the cutting fluid circulation system. The liquid level sensor monitors the amount of cutting fluid in the receiving box 2 to prevent cutting fluid shortage, while the pressure sensor monitors the pressure change of the cutting fluid during the circulation process to ensure that the bubble generator 3 works under appropriate pressure conditions. These designs significantly improve the stability and safety of the system and reduce production interruptions and equipment failures caused by insufficient cutting fluid supply or abnormal pressure.
