Description

Technical Field

[0001] This utility model relates to the field of cutting fluid preparation technology, and in particular to an automatic cutting fluid preparation device. Background Technology

[0002] Cutting fluid is an industrial liquid used to cool and lubricate cutting tools during metal cutting and other machining processes. Cutting fluids are generally formulated from a variety of additives and possess excellent cooling, lubrication, rust prevention, degreasing and cleaning properties, corrosion protection, and easy dilution characteristics.

[0003] Currently, the cutting fluid is prepared by mixing a certain amount of high-concentration cutting fluid with a diluent to obtain a cutting fluid of a certain concentration. However, during the mixing process, a stirring device is needed to mix and stir the cutting fluid for a certain period of time to avoid poor cooling and lubrication effects due to uneven mixing, which would affect the quality of the cutting fluid. This results in low efficiency of cutting fluid preparation and makes it impossible to quickly replenish the cutting fluid. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic cutting fluid dispensing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic cutting fluid dispensing device includes a dispensing tank, with an output pipe and a diluent injection pipe respectively provided at both ends of the dispensing tank. A delivery pipe for conveying the original cutting fluid is provided inside the dispensing tank. A liquid expansion cover is provided on the outer side of the output end of the delivery pipe, facing the diluent injection pipe. A liquid dispersion hole is opened on the outer periphery of the liquid expansion cover. Multiple buffer plates are staggered between the liquid expansion cover and the output pipe.

[0007] Preferably, the liquid preparation tank is provided with a mounting frame, the liquid expansion hood is rotatably mounted on the mounting frame, and the liquid expansion hood is provided with rotating blades facing the output end of the infusion tube.

[0008] Preferably, a guide cone is provided at the middle of the inner side of the liquid expansion shroud, and the rotating blades are distributed at intervals on the outer periphery of the guide cone.

[0009] Preferably, the mounting bracket has an inclined surface facing the diluent injection pipe.

[0010] Preferably, the output end of the infusion tube is connected to a flared tube facing the inside of the expansion hood.

[0011] Preferably, a stock solution tank is provided on one side of the liquid preparation tank, and a delivery pump connected to an infusion pipe is installed on the stock solution tank. A suction pipe extending into the stock solution tank is connected to the delivery pump.

[0012] Preferably, a fixing frame is provided inside the liquid preparation tank, and the infusion tube is fixed on the fixing frame.

[0013] Preferably, a rotating shaft is rotatably mounted on the mounting bracket, and the liquid diffuser is fixed on the rotating shaft.

[0014] The beneficial effects of this utility model are:

[0015] High-concentration cutting fluid concentrate and diluent are supplied to the mixing tank via an infusion pipe and a diluent injection pipe, respectively. A diffusion shroud is installed on the outside of the output end of the infusion pipe. The cutting fluid concentrate supplied by the infusion pipe can diffuse relatively evenly to the outer periphery through the diffusion holes of the diffusion shroud and mix evenly with the diluent. This allows the cutting fluid to be mixed more fully and efficiently. The mixed cutting fluid is then buffered and slowed down by a buffer plate so that it can be directly delivered to the outside through the output pipe, thereby achieving the effect of quickly replenishing and using the cutting fluid.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1-4As shown, an automatic cutting fluid mixing device includes a mixing tank 1 for mixing cutting fluid. The mixing tank 1 has an output pipe 11 and a diluent injection pipe 3 at both ends. The mixing tank 1 is provided with a delivery pipe 21 for conveying the original cutting fluid. The delivery pipe 21 is located between the output pipe 11 and the diluent injection pipe 3. The mixing tank 1 is provided with a fixing frame 212, and the delivery pipe 21 is fixed on the fixing frame 212.

[0024] The diluent injection pipe 3 is used to deliver the diluent of cutting fluid into the mixing tank 1. A stock solution tank 2 is provided on one side of the mixing tank 1. The stock solution tank 2 contains a high concentration of cutting fluid stock solution. A delivery pump 22 connected to a delivery pipe 21 is installed on the stock solution tank 2. A suction pipe 23 extending into the stock solution tank 2 is connected to the delivery pump 22 so as to deliver the high concentration of cutting fluid stock solution into the mixing tank 1 through the delivery pipe 21.

[0025] The infusion pipe 21 and the diluent injection pipe 3 are arranged opposite to each other so that the high-concentration cutting fluid concentrate and the cutting fluid dilution can be mixed by mutual flushing, and then the mixed cutting fluid is output to the outside through the output pipe 11.

[0026] To improve the mixing efficiency and effect of the cutting fluid, the outer side of the output end of the infusion pipe 21 is provided with a dilution shroud 12 facing the diluent injection pipe 3. The dilution shroud 12 is bowl-shaped and its opening faces the output end of the infusion pipe 21, so that the high-concentration cutting fluid concentrate delivered by the infusion pipe 21 can flow to the inside of the dilution shroud 12. The bottom of the dilution shroud 12 is set towards the diluent injection pipe 3, so that the cutting fluid dilution can flow to the dilution shroud 12 and flow to the outside of the dilution shroud 12.

[0027] The outer periphery of the liquid expansion cover 12 is provided with a liquid dispersing hole 122, so that the cutting fluid stock can diffuse to the outer periphery relatively evenly through the liquid dispersing hole 122 of the liquid expansion cover 12. At this time, the cutting fluid stock divided into small streams through the liquid dispersing hole 122 is evenly mixed with the diluent, so that the cutting fluid can be mixed more fully and efficiently.

[0028] Furthermore, the output end of the infusion tube 21 is connected to a flared tube 211 facing the inside of the expansion shroud 12. The flared tube 211 is configured to allow the cutting fluid concentrate to flow more slowly into the expansion shroud 12. A guide cone 121 is provided in the middle of the inside of the expansion shroud 12. The guide cone 121 guides the cutting fluid concentrate delivered by the infusion tube 21 so that the cutting fluid concentrate can flow more smoothly to the dispersing hole 122 and mix with the diluent.

[0029] The liquid preparation tank 1 is provided with a mounting frame 13, and the liquid expansion cover 12 is rotatably mounted on the mounting frame 13. Specifically, a rotating shaft 132 is rotatably mounted on the mounting frame 13, and the liquid expansion cover 12 is fixed on the rotating shaft 132. The mounting frame 13 is provided with an inclined surface 131 facing the diluent injection pipe 3, so as to reduce the obstruction of the mounting frame 13 to the flow of diluent.

[0030] The liquid expansion shroud 12 is provided with rotating blades 123 facing the output end of the infusion pipe 21. The rotating blades 123 are spaced apart on the outer periphery of the guide cone 121. When the cutting fluid concentrate flows out of the infusion pipe 21, the cutting fluid concentrate pushes the liquid expansion shroud 12 to rotate through the rotating blades 123, so that the cutting fluid concentrate flowing outward can be further dispersed through the rotating liquid expansion shroud 12 and the liquid dispersing hole 122, so that the cutting fluid concentrate can be mixed with the diluent more quickly and efficiently.

[0031] This eliminates the need for external stirring devices to mix the cutting fluid, ensuring the mixing effect while saving time and equipment costs. Furthermore, the rapid mixing design of the cutting fluid in this embodiment enables quick mixing and replenishment, greatly improving the convenience of using the cutting fluid.

[0032] Multiple buffer plates 14 are staggered between the liquid expansion shroud 12 and the output pipe 11. The buffer plates 14 buffer and slow down the mixed cutting fluid to avoid the cutting fluid flow rate being too fast and causing local inconsistencies in its concentration. This allows the cutting fluid with a stable concentration to be directly delivered to the outside through the output pipe 11, so as to achieve the effect of quickly replenishing and using the cutting fluid.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
