Description

Technical Field

[0001] The utility model relates to the technical field of cutting fluid production, in particular to an automatic liquid dispensing device for cutting fluid. Background Art

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. Cutting fluid is scientifically compounded with a variety of super-functional additives, and has good cooling performance, lubrication performance, rust prevention performance, oil removal and cleaning function, anti-corrosion function, and easy dilution. It overcomes the problems of traditional soap-based emulsions that are easy to stink in summer, difficult to dilute in winter, and have poor anti-rust effect. The existing cutting fluid needs to be diluted with water in the production process to make the high-concentration cutting fluid have the best lubrication and protection performance. In the process of water injection and liquid preparation, a special liquid preparation device is required.

[0003] In view of this, Chinese patent number CN217312830U proposes an automatic liquid dispensing device for cutting fluid. In the utility model, the structure of the automatic liquid dispensing device for cutting fluid has the characteristics of reasonable design, convenient operation, easy observation, automatic proportioning operation, and high accuracy, and is worthy of vigorous promotion and use. However, the existing cutting fluid dispensing device is only provided with a mixing and stirring device for liquid mixing when dispensing, and the cutting fluid itself has an oily mixture. After the liquid is mixed in the container for a long time, a large amount of oily liquid remains on the inner wall of the container. Long-term accumulation is likely to cause the transparent observation area to be blurred, and the inner wall of the container is oily and oxidized, which not only affects the staff's observation of the liquid when dispensing, but even the oily residue on the inner wall will be mixed in and reduce the use effect of the cutting fluid. In this regard, an automatic liquid dispensing device for cutting fluid is proposed in this design scheme. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0021] The examples are as follows:

[0022] The utility model provides Figure 1-4 The automatic liquid dispensing device for cutting fluid shown in the figure comprises a liquid dispensing box 1 and a mixing mechanism 2 installed inside the liquid dispensing box 1;

[0023] The mixing mechanism 2 includes a support frame 201 inserted and installed in the inner wall of the liquid distribution box 1, the inner wall of the support frame 201 is fixedly provided with a mounting bracket 202, the bottom of the mounting bracket 202 is rotatably provided with a stirring blade 203, a rubber scraper 204 is fixedly provided at the lower edge of the outer wall of the support frame 201, and the outer wall of the rubber scraper 204 is in contact with the inner wall of the liquid distribution box 1, a waterproof cover 205 is fixedly provided on the top of the mounting bracket 202, a motor 206 is installed inside the waterproof cover 205, and the stirring blade 203 is fixedly provided with a waterproof cover 205. One end passes through the inner wall of the waterproof cover 205 and is fixedly connected to the output end of the motor 206. A connecting shaft 207 is fixedly provided on the top of the waterproof cover 205. One end of the connecting shaft 207 passes through the outer wall of the top of the liquid distribution box 1 and is connected to a connecting plate 208. Installing the motor 206 through the waterproof cover 205 can effectively protect the motor 206 and prevent the motor 206 from being damaged by water. The rubber scraper 204 is made of rubber material, which improves the cleaning effect while reducing damage to the inner wall of the liquid distribution box 1 and the transparent panel 6.

[0024] An electric telescopic rod 209 is fixedly provided on one side of the top of the liquid distribution box 1, and the output end of the electric telescopic rod 209 is fixedly connected to one side of the bottom of the connecting plate 208. When the connecting shaft 207 is inserted into the top of the liquid distribution box 1, it always keeps in contact with the inner wall of the liquid distribution box 1, so that it is in a sealed state;

[0025] Furthermore, a liquid outlet hole 3 is opened on one side of the bottom of the inner wall of the liquid distribution box 1, and a drain pipe 4 is inserted on one side of the bottom of the liquid distribution box 1, and the inner wall of one end of the drain pipe 4 is connected to the inner wall of the liquid outlet hole 3, and the liquid outlet hole 3 is designed to be concave around, so as to facilitate the discharge of all the cutting fluid.

[0026] A first sealing valve 5 is rotatably provided on one side of the liquid dispensing tank 1, a through groove is provided on one side of the liquid dispensing tank 1, a transparent panel 6 is installed on the inner wall of the through groove, and a scale line is provided on the outer wall of the transparent panel 6. When the cutting fluid in the liquid dispensing tank 1 is stirred and mixed, the first sealing valve 5 is rotated to guide the cutting fluid from the liquid outlet 3 into the liquid dispensing tank 4 and discharged for collection;

[0027] Furthermore, liquid guide tubes 7 are inserted at the edges of both sides of the top of the liquid distribution box 1, and liquid storage barrels 8 are fixedly provided at the tops of the liquid guide tubes 7. Liquid inlet tubes 9 are inserted at the tops of the two liquid storage barrels 8. Second sealing valves 10 are installed at the lower edges of one side of the two liquid guide tubes 7, and sealing covers are threadedly installed on the two liquid inlet tubes 9. When no liquid is introduced, they can be tightened to prevent dust from entering. When guiding liquid, the second sealing valves 10 can be unscrewed one after another, and the liquid distribution amount can be controlled by the scale line indication on the transparent panel 6.

[0028] Working principle: When using the automatic liquid dispensing device for cutting fluid in this design, firstly, the cutting fluid with a high concentration and clean water are respectively injected into the two liquid storage barrels 8 through the liquid inlet pipe 9, and then the cutting fluid and clean water are quantitatively injected into the liquid dispensing box 1 by controlling the switch of the second sealing valve 10. The specific amount can be determined by the scale lines on the transparent panel 6. The cutting fluid and clean water need to be injected in sequence to control the injection amount. After the liquid injection is completed, the electric telescopic rod 209 and the motor 206 in the waterproof cover 205 are started to make the connecting shaft 207 descend under the pressure of the connecting plate 208. At the same time, the stirring blades 203 are driven to rotate by the motor 206, and after contacting the liquid, they are continuously stirred to make it fully mixed. During the mixing, the support frame 201 also descends along with the rise and fall of the connecting shaft 207, and the rubber scraper 204 is continuously scraped on the inner wall of the liquid distribution box 1 to scrape off the liquid and oily substances attached to the inner wall to make it fully mixed with the batch of cutting fluid. At the same time, the rubber scraper 204 on one side continuously scrapes the inner side of the transparent panel 6 to scrape its surface clean, so that the staff can observe the internal liquid more clearly, thereby improving the liquid distribution effect of the cutting fluid.
