[0029] 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.

[0030] like Figures 1-5 As shown, this utility model provides an automatic cutting fluid mixing and supply machine, which is particularly suitable for automated production lines or machining, for accurately mixing and stably supplying cutting fluid to improve production efficiency and product quality.

[0031] The automatic cutting fluid mixing and supply machine is mainly supported by a frame 1, on which a container 2, an aeration mechanism 3, a mixing mechanism 4, a supply mechanism 5, and a control unit 6 are installed. The control unit 6 is used to control the operation of the aeration mechanism 3, the mixing mechanism 4, and the supply mechanism 5. These components work together to realize the automatic mixing and supply of cutting fluid.

[0032] The container body 2 is internally divided into four independent chambers: a pure water chamber 201, a stock solution chamber 202, a mixing chamber 203, and a storage chamber 204. The pure water chamber 201 stores pure water, and the stock solution chamber 202 stores the cutting fluid stock solution. The mixing chamber 203 is where pure water and the stock solution are mixed; the required cutting fluid is prepared by precisely controlling the ratio of the two liquids. The storage chamber 204 is used to temporarily store the mixed cutting fluid for immediate use by the fluid supply mechanism 5.

[0033] A transfer pump 205 is installed on the outside of the container body 2. This pump is connected to the mixing chamber 203 and the storage chamber 204 through a pipeline and is responsible for transferring the mixed cutting fluid from the mixing chamber 203 to the storage chamber 204. In addition, the container body 2 is also equipped with a stock solution injection pump 206 for replenishing the stock solution chamber 202 with the cutting fluid stock solution.

[0034] The aeration mechanism 3 includes an aerator 301 disposed at the bottom of the mixing chamber 203 and the storage chamber 204, and an aeration fan 302 that provides air to the aerator. The aerator 301 is connected to a power supply 303 installed on the top of the container body 2 via a pipe, ensuring that air can be blown evenly into the two chambers, which helps to achieve uniform mixing of the cutting fluid and increase dissolved oxygen, thereby improving the performance of the cutting fluid. When the aeration fan 302 is installed, several cover plates 207 are installed on the top of the container body 2 to cover the pure water chamber 201, the stock solution chamber 202, the mixing chamber 203, and the storage chamber 204, and the aeration fan 302 is installed on one of the cover plates 207.

[0035] The proportioning mechanism 4 is composed of a proportioner 401, a manual flow control valve 402, a proportioning pump 403, a proportioning meter 404 and a concentration detector 405. The proportioner 401 has two input ends, which are connected to the pure water chamber 201 (water is supplied by a water pump 406) and the stock solution chamber 202 (flow is adjusted by the manual flow control valve 402) respectively. When starting operation, the pure water and the stock solution are proportioned according to the flow adjusted by the proportioner 401 and the manual flow control valve 402, and then flow into the proportioning chamber 203. The concentration detector 405 detects the concentration of the mixed solution in the proportioning chamber 203 by using a concentration detection pump 407, and feeds back the detection result to the control unit 6. The control unit 6 automatically adjusts the rotating speed of the proportioning pump 403 according to the concentration information. At this time, the proportioning pump 403 is responsible for pumping the stock solution from the stock solution chamber 202 into the proportioning chamber 203, and the proportioning meter 404 is installed on the pipeline to monitor the delivery amount of the stock solution, so as to accurately control the delivery amount of the stock solution and ensure the proportioning accuracy of the cutting fluid.

[0036] The liquid supply mechanism 5 is composed of a plurality of liquid supply pumps 501, a liquid supply pipe 502 and a liquid supply meter 503. The input ends of the liquid supply pumps 501 are connected to the storage chambers 204 respectively, and the output ends are connected to the liquid supply pipe 502. The liquid supply pipe 502 is provided with the liquid supply meter 503 for recording the supply amount of the cutting fluid. In order to maintain the stability of the supply pressure, the input end of the liquid supply pipe 502 is also provided with a constant pressure tank 504. At the same time, the liquid supply pipe 502 is also provided with a return pipe 505 between the liquid supply pipe 502 and the storage chamber 204, so as to return part of the cutting fluid when needed, and adjust the pressure or temperature of the liquid supply system.

[0037] The control unit 6 serves as the command center of the whole system, receives signals from the liquid level sensor 7, the floating ball water level controller 8 and the concentration detector 405, and controls the actions of each execution mechanism according to the preset program or operation instruction. The liquid level sensor 7 and the floating ball water level controller 8 are installed in each chamber respectively, and monitor the water level change in real time, so as to ensure the continuity and safety of the liquid supply. The liquid level sensor 7 is used for detecting the water level of the liquid in real time, while the floating ball water level controller 8 is used for detecting the highest water level. In addition, the rack 1 is also provided with a warning lamp 9 connected to the control unit 6, which is used for issuing a warning signal in abnormal conditions, so as to remind the operator to handle in time.

[0038] In summary, the application provides a cutting fluid automatic proportioning and supplying machine which is compact in structure, simple in operation and accurate in proportioning, and effectively improves the utilization efficiency of cutting fluid and the automation level of production line.
