[0022] 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.

[0023] Please see Figure 1-5 A quantitative stirring device for producing coolant includes a fixed frame 1, a stirring tank 2 fixedly installed inside the fixed frame 1, a quantitative structure 3 fixedly installed at the bottom of the stirring tank 2, and a stirring structure 5 fixedly installed at the top of the stirring tank 2. The quantitative structure 3 includes a discharge port 31, a sliding baffle 32 slidably installed inside the discharge port 31, a pull handle 33 fixedly installed at the bottom of the sliding baffle 32, a threaded port 34 fixedly installed on one side of the sliding baffle 32, first side blocks 35 fixedly installed on both sides of the outer surface of the discharge port 31, second side blocks 36 fixedly installed on both sides of the outer surface of the sliding baffle 32, limit rods 37 fixedly installed on one side of the two second side blocks 36, the two limit rods 37 being movably connected to the first side blocks 35, a liquid outlet tank 38 threadedly installed inside the threaded port 34, an inspection window 39 and a scale groove 310 opened on one side of the outer surface of the liquid outlet tank 38.

[0024] Please see Figure 1-3The mixing tank 2 has a feeding port 7 and a water inlet 8 at its top. A support frame 4 is fixedly installed on the outer surface of the fixing frame 1. The mixing structure 5 includes a fixing ring 51 and a pulley assembly 53. A servo motor 52 is fixedly installed inside the fixing ring 51. The pulley assembly 53 is rotatably connected to the mixing tank 2, and one end of the output shaft of the servo motor 52 is fixedly connected to the pulley assembly 53. A stirring rod 54 is fixedly installed at the bottom of the pulley assembly 53, and the stirring rod 54 is rotatably connected to the mixing tank 2.

[0025] Driven by the servo motor 52, its output shaft drives a pulley to rotate. Due to the belt connection, another pulley drives the stirring rod 54 to rotate, thereby enabling the stirring rod 54 to uniformly stir the raw materials inside the mixing tank 2.

[0026] Please see Figure 1 and Figure 5 A feeding structure 6 is fixedly installed on one side of the outer surface of the fixed frame 1. The feeding structure 6 includes a support block 61. A ladder 62 is fixedly installed on one side of the outer surface of the support block 61, and a fixing rod 63 is fixedly installed on the top of the support block 61. A rotating disk 64 is rotatably installed on the outer surface of the fixing rod 63, and four feeding tanks 65 are fixedly installed inside the rotating disk 64.

[0027] When preparing the coolant, the coolant raw materials are injected into the feeding tank 65 in advance. Then, the rotating disk 64 is rotated to make the different feeding tanks 65 align with the feeding port 7 for adding the medicine. After the medicine is added, water can be added into the mixing tank 2 through the water inlet 8. Then, the raw materials and water can be stirred and mixed by the stirring structure 5 to complete the preparation of the coolant.

[0028] Working principle: When a quantitative stirring device for coolant preparation is used, the coolant raw materials are first injected into the feeding tank 65 before preparation. Then, the rotating disc 64 is rotated to align the different feeding tanks 65 with the feeding port 7 for dosing. After dosing, water is added into the stirring tank 2 through the water inlet 8. Subsequently, the servo motor 52 drives its output shaft to rotate a pulley. Due to the belt connection, another pulley drives the stirring rod 54 to rotate, thereby allowing the stirring rod 54 to move against the inside of the stirring tank 2. The raw materials are uniformly stirred to complete the preparation of the coolant. After the coolant is prepared by the stirring structure 5, the outlet tank 38 is screwed into the threaded port 34. Then, the sliding baffle 32 is pulled backward by the pull handle 33 so that the threaded port 34 is aligned with the through hole of the outlet port 31. At this time, the coolant inside the stirring tank 2 flows into the outlet tank 38 through the sliding baffle 32. The amount of coolant inside the outlet tank 38 can be observed through the inspection window 39. After the amount of coolant is reached, the sliding baffle 32 is blocked by pushing the pull handle 33 in the opposite direction to block the through hole of the outlet port 31.
