Side blocks that slide in the two ends of the inner groove are fixed on the two side walls of the inner end of the main section. A number of rollers are rotatably installed on the side walls of each side block close to the outer groove. The peripheral walls of these rollers roll and rub against the corresponding side walls of the inner groove. An elastic member is installed in the middle of the inner end of the main section. A number of rollers are also rotatably installed on the elastic member to make the inner end of the elastic member roll and rub against the inner side wall of the inner groove.

[0010] The elastic member includes a slide groove and a slider. The slide groove is arranged at the inner end of the main section and extends outward. The slider is slidably installed in the slide groove.

Since the reciprocating transmission part includes a transmission gear set and a gear ring, it can be changed. With the variable transmission ratio, the speed of the lever's circular motion around the axis of the stirring shaft is lower than the speed of the stirring paddles' circular motion around the axis of the stirring shaft. Without changing the direction of rotation of the motor, the stirring paddles will turn over once after rotating around the stirring shaft for several times, thereby generating turbulence in the raw materials. The turbulence can make the fluid flow more widely in the stirring area, breaking the conventional laminar flow state, and allowing fluids originally in different positions and with different properties to interweave and exchange positions more quickly, thereby improving the stirring efficiency and eliminating the need for the motor to frequently switch between forward and reverse rotations, thereby increasing the service life of the motor.

[0019] The real stone paint stirring kettle provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0020] Example: like Figures 1 to 6As shown, the embodiment of the present application provides a real stone paint stirring kettle, including a kettle body 1, an inlet 11, an outlet 12, a motor 13, a stirring shaft 14 and a stirring paddle 15, and also includes a sealing cover 21, a plurality of rotating shafts 22, a plurality of linkage parts 23 and a reciprocating transmission part 24. The sealing cover 21 is cylindrically sleeved on the outside of the stirring shaft 14, and a plurality of rotating rings 211 are rotatably installed on the peripheral wall. A plurality of rotating shafts 22 distributed at intervals are rotatably penetrated on the peripheral wall of each rotating ring 211, and the outer end of each rotating shaft 22 is fixedly connected to the stirring paddle 15, and the inner end is rotatably connected to the stirring shaft 14. The upper and lower adjacent rotating shafts 22 are mutually transmission-connected through the corresponding linkage parts 23, and each linkage part 23 is connected to the reciprocating transmission part 24. The reciprocating transmission part 24 is rotatably connected to the stirring shaft 14. When the rotating shaft 22 rotates, the reciprocating transmission part 24 drives each linkage part 23 to reciprocate, so that each rotating shaft 22 swings back and forth around its own axis. The linkage part 23 includes a plurality of racks 231 and a plurality of linkage gears 232. Each linkage gear 232 is fixed on each rotating shaft 22. A plurality of linkage gears 232 adjacent to each other are connected by the same rack 231. The top of each rack 231 is fixed to the reciprocating transmission part 24. The reciprocating transmission part 24 includes a floating sleeve 241, a transmission gear set 242, a gear ring 243, a transmission groove 244 and a lever 245, which is sleeved on the outside of the stirring shaft 14, and the top end is fixedly connected to the top of the inner cavity of the kettle body 1, the bottom end of the floating sleeve 241 is fixedly connected to the top of each rack 231, the lever 245 is fixed on the outer wall of the gear ring 243, and slides with the transmission groove 244, the transmission gear set 242 is used to make the gear ring 243 and the stirring shaft 14 transmission connection, the transmission groove 244 is two parts connected to each other, and the heights of the two parts are different.

[0021] Furthermore, the sealing cover 21 includes a plurality of fixed covers 212 and a plurality of rotating rings 211. The fixed covers 212 and the rotating rings 211 are arranged at intervals and are rotatably connected to each other. The topmost and bottommost covers are both fixed covers 212 and are fixedly connected to the inner cavity of the kettle body 1. The fixed covers 212 between adjacent rotating rings 211 are fixedly installed on the inner cavity peripheral wall of the kettle body 1 through a plurality of support rods 213.

[0022] Furthermore, the sealing cover 21 also includes a plurality of sealing ring grooves 214, which are arranged on the end faces of each fixed cover 212 and the adjacent rotating ring 211, and a sealing ring is sleeved inside.

[0023] Furthermore, the linkage part 23 also includes a bottom plate 233, a plurality of T-shaped grooves 234 and a plurality of T-shaped rods 235. The bottom plate 233 is fixedly arranged at the bottom end of the rotating shaft 22, and the peripheral wall slides and rubs with the peripheral wall of the sealing cover 21. The top surface is fixedly connected to the lower end of each T-shaped rod 235. Each T-shaped groove 234 is vertically arranged on the side wall of each rack 231 away from the corresponding linkage gear 232, and slides with each T-shaped rod 235.

[0024] Furthermore, the transmission groove 244 is annularly arranged on the inner wall of the floating sleeve 241, including a lower retaining section 2441, an ascending section 2442, an upper retaining section 2443 and a descending section which are sequentially connected end to end, and the horizontal height of the lower retaining section 2441 is lower than that of the upper retaining section 2443.

[0025] In this embodiment of the present application, due to the adoption of the above-mentioned structure, various raw materials are put into the kettle body 1 through the feed port 11, and then the motor 13 is started to rotate the stirring shaft 14, a plurality of rotating shafts 22, a plurality of rotating rings 211, a bottom plate 233, a plurality of racks 231, a plurality of T-shaped rods 235 and a floating sleeve 241 with the axis of the stirring shaft 14, and at the same time, the transmission gear set 242 drives the ring gear 243 and the lever 245 to rotate in the same direction as the stirring shaft 14, but the rotation speed is lower than that of the stirring shaft 14, resulting in the higher part of the transmission groove 244 on the inner circumferential wall of the floating sleeve 241 that rotates faster chasing the slower rotating lever 245 to rotate, and the horizontal height of the ring gear 243 is fixed, so the upper retaining section 2443 / lower retaining section 2441 of the transmission groove 244 rotates to the same direction as the stirring shaft 14. When the lever 245 cooperates, the lever 245 moves the transmission slot 244 and the floating sleeve 241 to descend / rise together. Correspondingly, the racks 231 installed at the bottom of the floating sleeve 241 also descend / rise together with the floating sleeve 241, and cooperate with the corresponding linkage gear 232 to drive the corresponding rotating shaft 22 to rotate about its own axis to adjust the angle of the stirring paddle 15. Since the transmission gear set 242 changes the transmission ratio, the rotation speed of the ring gear 243 is lower than that of the floating sleeve 241. Therefore, after the floating sleeve 241 rotates around the axis of the stirring shaft 14 for many cycles, the lever 245 will enter the upper holding section 2443 / lower holding section 2441 from the lower holding section 2441 / upper holding section 2443 of the transmission slot 244 through the ascending section 2442 / descending section, thereby achieving the following effects: Each stirring paddle 15 is first rotated around the axis of the stirring shaft 14 for multiple cycles with the height of the side facing the fluid lower than the height of the other side in this manner, and the raw materials in the kettle body 1 are stirred upward. After each stirring paddle 15 rotates around the axis of the stirring shaft 14 for multiple cycles, the lever 245 enters the other part of the transmission groove 244 (enters the lower part from the higher part of the transmission groove 244). At this time, under the cooperation of each rack 231 and the linkage gear 232, the rotating shaft 22 and the stirring paddle 15 rotate around the axis of the rotating shaft 22, so that the height of each stirring paddle 15 facing the fluid side is gradually higher than the other side. The height of the side of the stirring paddle 15 is gradually lower than the height of the other side, and the raw materials in the inner cavity of the kettle body 1 are stirred downward. In this process, there is no need to frequently change the direction of the motor 13, thereby avoiding the following problems: 1. When the motor 13 changes direction, the internal mechanical parts such as bearings and gears will be subjected to greater impact and alternating stress, which will accelerate the wear of these parts and reduce the precision of the parts, thereby affecting the overall performance and service life of the motor 13; 2. Every time the motor 13 changes direction, it needs to overcome the inertia of the rotor and the back electromotive force in the winding, which will cause the motor 13 to consume a large current in a short time. Frequent switching of direction will cause the motor 13 to continue in this high current working state, thereby generating more heat. Long-term overheating will cause the insulation material performance of the motor 13 to deteriorate, accelerate insulation aging, and may even cause insulation breakdown, causing damage to the motor 13.

[0026] The plurality of rotating shafts 22 distributed on the rotating ring are vertically opposite to the plurality of rotating shafts 22 on the adjacent rotating rings. When each rack 231 is lifted or lowered, each T-shaped rod 235 lifts or slides in the corresponding T-shaped groove 234 to keep each rack 231 lifted or lowered vertically.

[0027] Furthermore, the T-shaped groove 234 includes an inner groove 2341 and an outer groove 2342. The width of the inner groove 2341 is greater than the width of the outer groove 2342. The outer groove 2342 is arranged on the toothless side wall of the rack 231. The inner groove 2341 passes through the outer groove 2342 from top to bottom, and the middle part is connected to the inner end of the outer groove 2342. The T-shaped rod 235 includes a main section slidably installed in the middle section of the outer groove 2342 and the inner groove 2341, and side blocks are fixed on the two side walls of the inner end of the main section, which slide in the two ends of the inner groove 2341 respectively. A number of rollers 4 are rotatably installed on the side walls of each side block close to the outer groove 2342, and the peripheral walls of these rollers 4 roll and rub against the corresponding side walls of the inner groove 2341. An elastic member 3 is installed in the middle of the inner end of the main section, and a number of rollers 4 are also rollably installed on the elastic member 3, which is used to make the inner end of the elastic member 3 roll and rub against the inner side wall of the inner groove 2341.

[0028] Furthermore, the elastic member 3 includes a slide groove 31 and a slider 32. The slide groove 31 is arranged at the inner end of the main section and extends outward. The slider 32 is slidably installed in the slide groove 31. A plurality of rollers 4 are installed at one end, and a plurality of pressure springs 33 are arranged at intervals from top to bottom at the other end. The two ends of each pressure spring 33 are respectively fixed to the adjacent side walls of the slider 32 and the slide groove 31.

[0029] Furthermore, the transmission gear set 242 includes a central gear 2421 and a plurality of transmission gears 2422 . Each transmission gear 2422 is rotatably mounted on the outer side of the rotating shaft 22 via a same fixing sleeve 2423 , and meshes with the ring gear 243 and the central gear 2421 simultaneously.

[0030] Furthermore, the reciprocating transmission part 24 also includes an annular groove 25 and a plurality of buckle shells 26. The annular groove 25 is arranged on the inner side of the bottom surface of the gear ring 243. The buckle shells 26 are distributed at intervals along the circumferential direction and fixed at the bottom end of the fixed sleeve 2423. They all include a connecting portion 261 and a bending portion 262. The bending portion 262 extends into the annular groove 25 and slides with the annular groove 25.

[0031] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when each rack 231 is lifted and lowered together with the floating sleeve 241, each T-slot 234 slides along the corresponding T-rod 235, and each roller 4 rolls with the side wall corresponding to the inner groove 2341, thereby reducing the friction between each T-rod 235 and each slider 32 and the inner wall of the corresponding T-slot 234. At the same time, each pressure spring 33 applies pressure to the corresponding slider 32, so that the outer end of the slider 32 applies pressure to the corresponding rack 231, so that each rack 231 is tightly meshed with the corresponding linkage gear 232, thereby compensating for the friction loss between each linkage gear 232 and each rack 231.

[0032] The rotation of the rotating shaft 22 drives the central gear 2421 (that is, the sun gear in the planetary gear set) to rotate, and then drives the transmission gears 2422 (planetary gears) to rotate, and drives the outer ring gear 243 (planetary carrier) to rotate. The bent portion 262 slides with the annular groove 25 to make the ring gear 243 rotatably installed at the bottom end of the fixed sleeve 2423 to achieve reduction transmission. The rotation speed of the shifting rod 245 is lower than the rotation speed of the floating sleeve 241.

[0033] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0034] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
