The output shaft of the motor passes through the shell and is provided with a rotating disk. A first stirring assembly is disposed on the lower surface of the rotating disk. The first stirring assembly includes a plurality of stirring rods disposed along a direction away from the axis of the rotating disk. The top end of the stirring rod is hinged to the rotating disk and the hinge axis is perpendicular to the axis of the rotating disk.

[0032] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0034] Example 1, such as Figure 1-8 As shown, the present invention provides an environmentally friendly plant-based semi-synthetic cutting fluid, including a tank 1 and an adjustment structure 6. A cover 2 is installed on the upper surface of the tank 1, an inlet pipe 3 is installed on the upper surface of the cover 2, a drive device 4 is installed on the upper surface of the cover 2, a stirring rod 5 is installed on the lower surface of the drive device 4, a plurality of bolts 9 are installed on the inner wall of the cover 2, the arc surface of the plurality of bolts 9 is provided with the adjustment structure 6, the arc surface of the stirring rod 5 is provided with the auxiliary structure 7, and the arc surface of the tank 1 is provided with the moving structure 8.

[0035] The following section will explain the specific settings and functions of its adjustment structure 6, auxiliary structure 7, and moving structure 8.

[0036] like Figure 3 and Figure 4As shown, the adjusting structure 6 includes several nuts 601, which are threadedly connected to bolts 9. Small toothed rings 602 are fixedly connected to the arc surfaces of each nut 601. The arc surfaces of the small toothed rings 602 mesh with the same large toothed ring 603. A connecting plate 604 is fixedly connected to the lower surface of the large toothed ring 603. Several auxiliary tubes 605 are rotatably connected to the inner wall of the connecting plate 604. The auxiliary tubes 605 are fixedly connected to the small toothed rings 602. A mounting base 606 is fixedly connected to the arc surface of the auxiliary tubes 605. A connecting rod 607 is rotatably connected to the inner wall of the mounting base 606. An auxiliary plate 608 is fixedly connected to the arc surface of the connecting rod 607. A protective plate 610 is fixedly connected to the upper surface of the auxiliary plate 608. Two coil springs 609 are sleeved on the arc surface of the connecting rod 607. The two ends of the coil springs 609 are fixedly connected to the mounting base 606 and the auxiliary plate 608, respectively. The adjusting structure 6 can be adjusted by setting... Section 6 allows the nuts 601 on bolts 9 to be rotated uniformly, avoiding the traditional method of rotating individual nuts 601 one by one, thereby improving the ease and efficiency of installing cover 2. A fixing plate 612 is fixedly connected to the inner wall of the protective plate 610. The fixing plate 612 is an acrylic plate. Since the fixing plate 612 is an acrylic plate and is transparent, it is easy for personnel to observe the internal condition of the auxiliary tube 605. A soft pad 611 is fixedly connected to one side of the protective plate 610. The soft pad 611 is a rubber pad. The soft pad 611 can prevent the protective plate 610 from directly contacting the auxiliary tube 605 and prevent the auxiliary tube 605 from being worn. An anti-slip sleeve 613 is fixedly connected to the arc surface of the large toothed ring 603. The anti-slip sleeve 613 has anti-slip texture. The anti-slip sleeve 613 can increase the friction of the large toothed ring 603 and prevent personnel from slipping their hands when rotating the large toothed ring 603.

[0037] The effect of the entire adjustment structure 6 is that the nuts 601 on multiple bolts 9 can be rotated easily, improving the installation efficiency of the cover 2 and the tank 1.

[0038] like Figure 5 and Figure 6As shown, the auxiliary structure 7 includes a welding plate 701, which is fixedly connected to the stirring rod 5. An electric actuator 702 is fixedly connected to the lower surface of the welding plate 701. A connecting rod 703 is fixedly connected to the output end of the electric actuator 702. A mounting plate 704 is fixedly connected to the lower surface of the connecting rod 703. An auxiliary block 705 is fixedly connected to the lower surface of the mounting plate 704. The auxiliary block 705 and the stirring rod 5 are slidably connected. Telescopic rods 706 are fixedly connected to the sides of the auxiliary block 705. A limit frame 707 is fixedly connected to the other end of the telescopic rod 706. A spring 708 is fitted onto the arc surface of the container 1. The two ends of the spring 708 are fixedly connected to the limiting frame 707 and the auxiliary block 705, respectively. A scraper 709 is fixedly connected to one side of the limiting frame 707. By setting the auxiliary structure 7, the material inside the container 1 can be scraped off to avoid material residue affecting the stirring concentration. A bellows 710 is fitted onto the arc surface of the spring 708. The two ends of the bellows 710 are fixedly connected to the auxiliary block 705 and the limiting frame 707, respectively. The bellows 710 can protect the spring 708 to prevent foreign objects from getting stuck in the spring 708 during use.

[0039] The effect of the entire auxiliary structure 7 is that it can easily scrape off the residual material inside the tank 1.

[0040] like Figure 7 and Figure 8 As shown, the movable structure 8 includes a support plate 81, which is fixedly connected to the tank 1. A limit rod 82 is fixedly connected to the upper surface of the support plate 81. A positioning plate 83 is slidably connected to the arc surface of the limit rod 82. The positioning plate 83 is fixedly connected to the cover 2. A base plate 84 is fixedly connected to the arc surface of the tank 1. A servo motor 85 is fixedly connected to the upper surface of the base plate 84. A screw 86 is fixedly connected to the output end of the servo motor 85. A limit plate 87 is threadedly connected to the arc surface of the screw 86. The limit plate 87 is fixedly connected to the cover 2. The movable structure 8 is constructed by setting a limit plate 87. Structure 8 allows the cover 2 to open automatically, avoiding the need for manual opening and thus improving safety. The servo motor 85 is covered with a protective cover 88, which is fixedly connected to the base plate 84. The protective cover 88 protects the servo motor 85 from external impacts. The arc surface of the protective cover 88 has heat dissipation holes 89, which are evenly distributed on the protective cover 88. The heat dissipation holes 89 can improve the heat dissipation efficiency of the protective cover 88, making the servo motor 85 more stable during use.

[0041] The effect of the entire moving structure 8 is that it allows the lid 2 to open or close automatically.

[0042] The overall working principle is as follows: When it is necessary to install the cover 2 and the tank 1, first move the bolt 9 to insert it into the installation position of the cover 2 and the tank 1, then rotate the large toothed ring 603. The large toothed ring 603 engages synchronously, driving all the small toothed rings 602 to rotate together. The small toothed rings 602 are fixed to the nut 601 as a whole, thereby driving the nut 601 to rotate synchronously, so that the nut 601 is screwed in along the axial direction of the bolt 9, completing the threaded assembly of the nut 601 and the bolt 9. During the rotation of the large toothed ring 603, the connecting plate 604 at its bottom also rotates together. The connecting plate 604 supports multiple auxiliary tubes 605. The auxiliary tubes 605 are fixedly connected to the small toothed rings 602 and rotate with them. The mounting seat 606 on the outside of the auxiliary tube 605 rotates synchronously. The connecting rod 607 inside the mounting seat 606 will drive the auxiliary plate 608 and the protective plate 610 above to swing synchronously. The coil spring 609 fitted on the connecting rod 607 continuously generates elastic force, which can drive the connecting rod 607 to reset, so that the protective plate 608... The cover 2 is always attached to the outside of the assembly position of the nut 601 and bolt 9, forming a shield and protection for the installation area of ​​the nut 601 and bolt 9, preventing dust and debris from entering the threaded gap. As each set of nuts 601 is continuously tightened, the cover 2 is gradually pressed against the upper end face of the tank body 1, finally achieving a sealed fixation between the cover 2 and the tank body 1. The entire adjustment structure 6 relies on the linkage of each component to complete the synchronous tightening operation of the nuts 601, and through the protective plate 610 in conjunction with the coil spring 609, connecting rod 607 and other components, it provides long-term protection for the connection between the bolt 9 and the nut 601. Among them, since the fixing plate 612 is an acrylic plate that is transparent, it is convenient for personnel to observe the internal condition of the auxiliary tube 605. The soft pad 611 can prevent the protective plate 610 from directly contacting the auxiliary tube 605, preventing the auxiliary tube 605 from being worn. The anti-slip sleeve 613 can increase the friction of the large toothed ring 603, preventing the personnel's hands from slipping when rotating the large toothed ring 603.

[0043] When materials are added into tank 1 through feed pipe 3, drive device 4 is activated to rotate stirring rod 5. When stirring is in progress, welding plate 701 rotates synchronously with stirring rod 5. Electric actuator 702 installed on it is activated and drives connecting rod 703 to perform linear telescopic movement. Connecting rod 703 drives mounting plate 704 and auxiliary block 705 to slide along the axis of stirring rod 5. Telescopic rods 706 connected to both sides of auxiliary block 705 extend or retract accordingly. Limiting frame 707 adjusts its position based on telescopic rods 706. The spring 708, located on the outside of the telescopic rod 706, uses its own elasticity to constantly push the limiting frame 707 to maintain an outward tension. The components cooperate with each other to make the limiting frame 707 stably adhere to the inner wall of the tank 1, thereby completing the scraping operation of the material attached to the tank wall. The corrugated pipe 710 can protect the spring 708 to prevent foreign objects from getting stuck in the spring 708 during use. The scraper 709 can help the limiting frame 707 scrape the inside of the tank 1, thereby improving the scraping efficiency of the limiting frame 707.

[0044] When the operator needs to open or close the lid 2 on top of the tank 1, the support plate 81 and the base plate 84 fixed to the surface of the tank 1 provide overall support. The servo motor 85 is activated, and its output drives the screw 86 to rotate. The limiting plate 87, threaded onto the surface of the screw 86, moves vertically upwards and downwards due to the threaded transmission. Since the limiting plate 87 is fixedly connected to the lid 2, it causes the lid 2 to move synchronously upwards and downwards. A positioning plate 83 is fixed to one side of the lid 2, and the positioning plate 83 slides on the outer surface of the limiting rod 82. The limiting rod 82 is installed on the upper end of the support plate 81, enabling it to... The positioning plate 83 and the cover 2 serve as limit guides to prevent the cover 2 from shifting or shaking during lifting. The components work together to drive the screw 86 to rotate using the servo motor 85, which in turn guides and limits the movement of the limit rod 82. This enables the cover 2 to open and close automatically and smoothly, replacing manual opening and closing and improving the safety and automation of the equipment. The protective cover 88 protects the servo motor 85 from external impacts, and the heat dissipation holes 89 improve the heat dissipation efficiency of the protective cover 88, making the servo motor 85 more stable during use.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
