Description

Technical Field

[0001] This utility model relates to the field of concentration regulator technology, and in particular to an automatic regulator for grinding fluid concentration. Background Technology

[0002] Polishing fluid is a functional liquid used in mechanical polishing processes. It is typically composed of base oil, lubricant, coolant, rust inhibitor, and stabilizer. It is suitable for polishing materials such as metal, wood, and stone. It can prevent workpiece overheating and deformation by cooling and reduce wear on the polishing tools by lubricating. An automatic polishing fluid concentration regulator is an intelligent control device adapted to the polishing system. It consists of a concentration sensor, a metering pump, a mixing tank, and a PLC control system. It can monitor the concentration of the polishing fluid in real time. When the concentration is lower or higher than the set value, it automatically starts the metering pump to add the original liquid or diluent. By stirring and mixing, it maintains a stable concentration, which can replace manual adjustment, avoid concentration fluctuations affecting polishing accuracy, and reduce material waste.

[0003] The original technology for concentration regulators utilizes a concentration sensor. A slurry concentration sensor is installed inside the slurry tank. When the concentration of the grinding fluid in the tank does not meet the set range, a signal is transmitted to the programmable logic controller (PLC). The PLC then controls the grinding media tank to add grinding media to the slurry tank until the concentration reaches the upper limit of the specified range, at which point the addition stops, thus ensuring the automatic stability of the grinding fluid concentration in the tank. However, the dilution amount is entirely calculated automatically by the system based on the sensor signal and a preset program, and workers cannot directly intervene in the specific amount added. Existing technology uses a metering pump in conjunction with controlling the pump's running time to control the total inflow. Because the output of the metering pump is fixed per second and per minute, it is only necessary to calculate how long the pump needs to run to accurately control the total inflow. However, with long-term use, wear on the pump's impeller and sealing components causes the actual flow rate to deviate from the set value. The system still operates according to the original set time, resulting in errors in the material supply. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic grinder concentration regulator, which aims to improve the problem in the prior art where the system continues to operate according to the original settings after long-term use and wear, resulting in feeding errors.

[0030] 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.

[0031] Reference Figure 3 and Figure 4This utility model provides an embodiment of an automatic grinding fluid concentration regulator, comprising a mixing tank 1, a liquid dispensing mechanism 2 fixedly connected to the right side of the mixing tank 1 for quantitatively dispensing the diluent, and a stirring mechanism 3 rotatably connected inside the mixing tank 1 for rapidly mixing the grinding fluid and the diluent; the liquid dispensing mechanism 2 includes guide strips 201, multiple guide strips 201 are installed on the right side of the mixing tank 1, and square bowls 202 are slidably connected to adjacent sides of the multiple guide strips 201; a fixing post 203 is installed at the bottom of the square bowl 202, a guide pipe 204 is connected to the left side of the fixing post 203, and a pushing assembly 205 is installed at the bottom of the fixing post 203; the pushing assembly 205 includes an electric push rod 2051, the electric push rod 2051 is a DT type electric push rod, and its working principle is that the DT type electric push rod uses an electric motor as a power source, and after reduction... The speed gear drives the lead screw and nut pair to convert the rotational motion of the motor into linear motion. It consists of a drive motor, a reduction gear mechanism, a lead screw and nut pair, a limit device, and a push rod housing and connecting parts. The electric push rod 2051 is installed on the right side of the fusion tank 1. The output end of the electric push rod 2051 is fixedly connected to a hollow motion rod 2052. The top of the hollow motion rod 2052 is connected to the bottom of the square bowl 202. The outer wall of the hollow motion rod 2052 is slidably connected to the inner wall of the fixing hole column 203. The bottom of the guide strip 201 is fixedly connected to a diluent tank 4. The bottom of the diluent tank 4 is fixedly connected to a table 5. The bottom of the table 5 is fixedly connected to the outer wall of the fixing hole column 203. The four corners of the bottom of the table 5 are fixedly connected to support columns 6 near the edge. The middle of the support column 6 is fixedly connected to a support plate 7. The top of the support plate 7 is fixedly connected to the bottom of the electric push rod 2051.

[0032] Specifically, when the square bowl 202 is filled with diluent in the diluent tank 4, the electric push rod 2051 is activated, causing the hollow moving rod 2052, which is fixedly connected to it, to slide inside the fixed hole post 203. This, in turn, pulls the square bowl 202, which is fixed to the hollow moving rod 2052, to slide synchronously along the guide strip 201. When the hole on the hollow moving rod 2052 corresponds to the position of the guide tube 204, the diluent in the square bowl 202 will flow into the hollow moving rod 2052 through its own hole, and then be guided... Pipe 204 delivers the liquid into the fusion tank 1. The entire liquid dispensing mechanism 2 is supported by the table 5 and the support column 6, forming a stable overall structure. The electric push rod 2051 is stably supported by the support plate 7. This mechanism precisely adjusts the dosage of the diluent by pushing the electric push rod 2051, replacing the traditional pump delivery method. This effectively avoids the material ratio error caused by the pump impeller being damaged without being detected, thus improving the accuracy of liquid metering and the reliability of system operation.

[0033] Reference Figure 2 and Figure 5The stirring mechanism 3 includes a rotary motor 301, which is a miniature DC brushed geared motor. Its working principle is that the stator permanent magnet forms a magnetic field, and the current flows into the rotor coil through the brush and commutator. The electromagnetic force drives the rotor to rotate, and the commutator ensures continuous rotation. It consists of a DC brushed motor and a reduction mechanism. The rotary motor 301 is fixedly connected to the top of the fusion tank 1. The output end of the rotary motor 301 is fixedly connected to a bevel gear 302. The left side of the bevel gear 302 is meshed with a bevel gear 303. The bottom of the outer wall of the bevel gear 303 is fixedly connected to a fixing ring 304. The bottom of the bevel gear 303 is fixedly connected to a transmission column 305. The bottom of the transmission column 305 is fixedly connected to a paddle column 306. The outer wall of the paddle column 306 is fixedly connected with multiple paddle blades 307 at equal intervals.

[0034] Specifically, after both the polishing fluid and the diluent are injected into the fusion tank 1, the rotating motor 301 is started, which will drive the bevel gear 302, which is fixedly connected to it, to rotate synchronously. Since bevel gear 1 302 and bevel gear 2 303 mesh with each other, bevel gear 2 303 will rotate in the opposite direction as bevel gear 1 302 rotates. The fixing ring 304 fixed to bevel gear 2 303 is installed inside the top cover of the fusion tank 1. The stable connection between the fixing ring 304 and the top cover ensures that bevel gear 2 303 will not deviate during rotation, providing a stable support for subsequent transmission. At the same time, the transmission column 305 fixed to bevel gear 2 303 will rotate together with bevel gear 2 303, thereby driving the paddle column 306 fixed to it to rotate synchronously. When the paddle column 306 rotates, it will drive the paddle blade 307 on its outer side to stir at high speed inside the fusion tank 1, so that the grinding fluid and the diluent can fully contact and mix. Through the mechanical stirring action of the paddle blade 307, the fusion time of the two liquids is effectively shortened, and finally the grinding fluid and the diluent are quickly and uniformly fused, preparing a properly proportioned mixture for subsequent grinding operations.

[0035] Reference Figure 1 and Figure 2 The outer wall of the fusion tank 1 has an inflow hole 8 connected to the left side, and a grinding liquid tank 9 is slidably connected inside the inflow hole 8. The outer wall of the fusion tank 1 has a liquid outlet 10 connected to the left side, and a pump 11 is fixedly connected to the left side of the liquid outlet 10. The top of the fusion tank 1 has an exhaust hole 12, which is circular.

[0036] Specifically, the polishing fluid in the polishing fluid tank 9 is injected into the fusion tank 1 through the inlet hole 8. At the same time, the diluent in the liquid extraction mechanism 2 also flows into the fusion tank 1 through the guide pipe 204. After the two liquids are collected in the fusion tank 1, they are thoroughly stirred and mixed by the stirring mechanism 3 to form a uniform fusion liquid. After the mixing is completed, the exhaust hole 12 will balance the air pressure in the tank, and the pump 11 will smoothly extract the fusion liquid in the fusion tank 1 to provide the required mixed liquid for the subsequent polishing process. The whole process realizes the automatic proportioning, mixing and transportation of polishing fluid and diluent, ensuring the continuous and stable operation of polishing.

[0037] Working principle: When the square bowl 202 is filled with diluent, the electric push rod 2051 drives the fixed hollow moving rod 2052 to slide inside the fixed hole column 203, thereby pulling the square bowl 202, which is fixed to the hollow moving rod 2052, to slide inside the guide strip 201. When the hole in the hollow moving rod 2052 matches the guide pipe 204, the diluent flows from the hole in the square bowl 202 into the hollow moving rod 2052, and then flows into the fusion tank 1 through the guide pipe 204. The liquid taking mechanism 2 adjusts the amount of diluent by pushing the electric push rod 2051, thereby avoiding the problem of material error caused by the system continuing to run due to damage to the pump impeller.

[0038] When both the polishing fluid and the diluent are inside the fusion tank 1, as the rotating motor 301 is started, the rotating motor 301 drives the bevel gear 1 302 and bevel gear 2 303 fixed to it to mesh. As bevel gear 2 303 rotates, the fixing ring 304 fixed to bevel gear 2 303 is fixed inside the top cover of the fusion tank 1 to ensure rotational fixation. The transmission column 305 fixed to bevel gear 2 303 drives the paddle column 306 fixed to the transmission column 305 to rotate. Subsequently, the paddle column 306 drives the paddle blade 307 to stir the polishing fluid and diluent in the fusion tank 1, thereby achieving rapid fusion of the polishing fluid and the diluent.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
