[0002] Painting paint refers to special paint used on various painting media, including oil painting, acrylic painting, watercolor painting, etc. This type of paint not only has excellent color expression, but also provides good adhesion and durability. According to different usage media and effects, painting paint can be divided into many types, such as oil paint, acrylic paint, watercolor paint, pastel, marker paint, etc. Painting paint is widely used in traditional painting and modern art creation. Artists express their creativity and emotions by using different types of paint. During the production process of the paint, a stirring device is required to fully mix the liquid pigment and solvent to achieve a uniform and consistent effect.

[0003] A Chinese patent document with announcement number CN115301097B discloses a paint stirring device, comprising an outer stirring barrel with a feed port on the upper surface, a rotatable spiral power rod is arranged at the axis center inside the outer stirring barrel, and the outer circumference of the spiral power rod is covered with an inner stirring barrel, and the lower surface of the outer stirring barrel is provided with a power component for driving the spiral power rod and the inner stirring barrel to rotate, and a sealing cylinder connected to the interior of the inner stirring barrel is fixedly connected to the middle part of the outer circumference of the inner stirring barrel. By setting a blocking barrel, a fixing barrel and a shearing barrel, when the paint rises to the top of the inner stirring barrel, the paint will flow into the outer stirring barrel from the guide port, thereby prompting the paint in the outer stirring barrel to always maintain a flowing state, and when the shearing barrel rotates, it can shear the paint and destroy the lumps in the paint, thereby greatly increasing the effect of paint stirring.

[0004] However, the above patent still has the following shortcomings: when adding liquid pigment into the solvent by pouring, the liquid pigment needs to be stirred for a period of time before it can be dispersed to various parts of the solvent, which easily reduces the mixing efficiency of the liquid pigment and the solvent. Summary of the invention

[0005] The present invention provides a paint stirring device and a stirring method, aiming to solve the problem in the related art that when liquid pigment is added to a solvent by pouring, the liquid pigment needs to be stirred for a period of time before it can be dispersed to various parts of the solvent, which easily reduces the mixing efficiency of the liquid pigment and the solvent.

[0006] The paint stirring device of the present invention comprises a stirring rod, a stirring blade and a containing barrel, wherein the stirring blade is connected to the stirring rod, the stirring rod can extend into the containing barrel, and the stirring rod can also drive the stirring blade to stir the solvent in the containing barrel, and also comprises a dispersing mechanism, the dispersing mechanism comprises a lifting part, a dispersing part, a pushing part and a blocking part, the dispersing part is rotatably connected to the stirring rod, a plurality of liquid outlets are arranged on the dispersing part, and liquid pigment can be transported to different depths of the solvent, the dispersing part is plugged into the lifting part, the lifting part can limit the dispersing part so that the dispersing part does not rotate, a plurality of pushing parts are arranged, and the plurality of pushing parts are all slidably connected to the dispersing part and correspond to the plurality of liquid outlets one by one, the pushing part is connected to the lifting part, the lifting part can move down to the surface of the solvent, and drive the pushing part to push the pushing part one by one from top to bottom to block the liquid outlets leaking out of the surface of the solvent.

[0007] Beneficial effect: the lifting part drives the pushing part to move downward, and pushes the blocking part from top to bottom in sequence, thereby blocking the liquid outlet leaking out of the solvent surface, and the liquid pigment is evenly transported to different depths of the solvent through the liquid outlet extending into the solvent from the dispersing part, thereby improving the mixing efficiency of the solvent and the liquid pigment.

[0008] Preferably, an elastic part 1 is connected between the blocking part and the dispersing part for driving the blocking part to reset.

[0009] Preferably, the bottom of the pushing portion is provided with an inclined surface, which has the effect that the inclined surface on the pushing portion facilitates the blocking portion to move.

[0010] Preferably, the dispersion portion is connected to an infusion tube, which is connected to an external delivery device.

[0011] Preferably, the liquid outlet is connected to the second elastic part, and the second elastic part is connected to the sealing part, which can seal the liquid outlet. The effect is that the liquid outlet can be sealed by the sealing part, so that the liquid pigment can be filled in the dispersion part in advance, thereby preventing the air retained in the dispersion part from entering the solvent.

[0012] Preferably, a separation mechanism is also included, the separation mechanism includes a driving source 3, airbag 1 and airbag 2, a mounting groove 1 is arranged at the top of the lifting part, airway 1 and airway 2 are arranged in the lifting part, airway 1 and airway 2 are connected, airway 2 is connected to the mounting groove 1, the dispersion part and the pushing part are both arranged in the mounting groove 1, the driving source 3 is connected to the top of the lifting part, the airbag 1 is connected to the outer peripheral surface of the lifting part, and the airbag 2 is connected in the airway 2. The effect is that the lifting part, airbag 1 and airbag 2 can separate the liquid below the lifting part from the air above the lifting part, thereby reducing the bubbles generated when the solvent is stirred.

[0013] Preferably, the top of the lifting part is provided with a second mounting groove, and the separation mechanism further comprises a third airbag connected to the inner lower end of the second mounting groove. The effect is that when the dispersion part transports the liquid pigment into the solvent, the liquid below the lifting part pushes the third airbag upward, so that the third airbag bulges upward, thereby leaving enough space for the addition of the liquid pigment, so as to avoid the increase of the pressure in the solvent and the liquid pigment, which affects the mixing effect and mixing efficiency of the solvent and the liquid pigment.

[0014] The present invention also provides a stirring method of a paint stirring device, which comprises the following steps: S1: Start the stirring rod to move downward, and drive the stirring blade and the dispersion part to extend into the container; S2: Start the lifting part to move down to the upper surface of the solvent, and drive the pushing part to push the blocking part from top to bottom in sequence to block the liquid outlet leaking out of the solvent surface; S3: Start the stirring rod to drive the stirring blade to rotate to stir the solvent, and start the dispersing part to transport the liquid pigment to different depths of the solvent through the liquid outlet extending into the solvent.

[0015] Beneficial effect: The liquid pigment is uniformly transported to different depths of the solvent through the liquid outlet on the dispersing part extending into the solvent, thereby improving the mixing efficiency of the solvent and the liquid pigment.

[0016] The beneficial effects of the present invention are: 1. After the dispersing part extends into the solvent in the barrel, the lifting part drives the pushing part to move downward, and pushes the blocking part from top to bottom in sequence, thereby blocking the liquid outlet leaking out of the solvent surface. At this time, the liquid pigment is evenly transported to different depths of the solvent through the liquid outlet extending into the solvent from the dispersing part, thereby improving the mixing efficiency of the solvent and the liquid pigment.

[0017] 2. When the dispersion part is filled with liquid pigment in advance, the liquid outlet on the dispersion part can be blocked by the sealing member to avoid air remaining inside the dispersion part, thereby avoiding affecting the mixing effect of the solvent and the liquid pigment.

[0018] 3. Air is supplied to air passage one through driving source three to expand airbag one and airbag two. The outer peripheral surface of the expanded airbag one contacts the inner wall of the container, and the expanded airbag two is filled into mounting groove one to seal the mounting groove one. At this time, under the action of the lifting part, airbag one, airbag two and airbag three, the air above the lifting part and the solvent below the lifting part can be separated, thereby reducing bubbles generated when the stirring mechanism stirs the solvent, thereby enhancing the mixing effect of the solvent and the liquid pigment.

[0019] 4. When the liquid pigment is transported into the solvent, the liquid below the lifting part pushes the airbag three upward, so that the airbag three bulges upward, thereby leaving enough space for the addition of the liquid pigment to avoid the pressure increase in the solvent and the liquid pigment, which affects the mixing effect and mixing efficiency of the solvent and the liquid pigment.

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 9 As shown, the paint stirring device of the present invention comprises a stirring mechanism 1, a containing barrel 2, a clamping mechanism 3, a dispersing mechanism 4 and a separating mechanism 5. The containing barrel 2 is used for containing a solvent. The stirring mechanism 1 can stir the solvent in the containing barrel 2. The clamping mechanism 3 is connected to the stirring mechanism 1 and is used to clamp the containing barrel 2 to prevent the containing barrel 2 from tipping over when the solvent in the containing barrel 2 is stirred. The dispersing mechanism 4 is connected to the clamping mechanism 3 and is used to transport the liquid pigment to different depths of the solvent, thereby improving the mixing efficiency of the solvent and the liquid pigment. The separating mechanism 5 is connected to the dispersing mechanism 4 and is used to separate the solvent from the outside air, thereby reducing the generation of bubbles in the solvent during stirring, thereby enhancing the mixing effect of the solvent and the liquid pigment.

[0032] like Figure 1 and Figure 2 As shown, the stirring mechanism 1 includes a base 11, a lifting member 12, a driving member 13, a stirring rod 14 and a stirring blade 15. The lifting member 12 is connected to the top of the base 11, the driving member 13 is connected to the telescopic end of the lifting member 12, the stirring rod 14 is connected to the driving member 13, and the stirring blade 15 is connected to the stirring rod 14. The filling barrel 2 is placed on the top of the base 11, and the lifting member 12 can drive the driving member 13, the stirring rod 14 and the stirring blade 15 to move downward so that the stirring rod 14 and the stirring blade 15 extend into the filling barrel 2. The driving member 13 can drive the stirring rod 14 to rotate, so that the stirring rod 14 drives the stirring blade 15 to stir the solvent in the filling barrel 2 (the lifting member 12 and the driving member 13 are both prior art and will not be described in detail here).

[0033] like Figure 1 and Figure 2 As shown, the clamping mechanism 3 includes a driving source 31, a bidirectional screw 32 and a clamping portion 33. The driving source 31 is connected to the base 11, and the driving source 31 is a motor. One end of the bidirectional screw 32 is connected to the output shaft of the driving source 31, and the other end of the bidirectional screw 32 is rotatably connected to the base 11. The bidirectional screw 32 has two sections of threads with opposite spiral directions. The clamping portion 33 is set to two, and the two clamping portions 33 are respectively threadedly connected to the two sections of threads of the bidirectional screw 32, and the two clamping portions 33 are both slidably connected to the base 11.

[0034] The driving source 1 31 is started to drive the bidirectional screw rod 32 to rotate, and the bidirectional screw rod 32 drives the two clamping parts 33 to move closer to or farther away from each other on the base 11. When the two clamping parts 33 are close to each other, they can clamp the containing barrel 2 to prevent the containing barrel 2 from tipping over when the stirring mechanism 1 stirs the solvent in the containing barrel 2. When the two clamping parts 33 are farther away from each other, they can release the clamping of the containing barrel 2, so as to facilitate the removal of the containing barrel 2 from the base 11.

[0035] like Figures 1 to 6 As shown, the dispersion mechanism 4 includes a second driving source 41, a lifting part 42, a dispersion part 43, a pushing part 44, an infusion tube 45, a blocking member 46 and a sealing member 47. The second driving source 41 is connected to the driving member 13. The second driving source 41 is a cylinder. The lifting part 42 is connected to the telescopic end of the second driving source 41. The dispersion part 43 is rotatably connected to the stirring rod 14, and the dispersion part 43 is plugged into the lifting part 42. The lifting part 42 can limit the dispersion part 43 so that the dispersion part 43 cannot rotate with the stirring rod 14. The bottom of the dispersion part 43 and the bottom of the stirring rod 14 are located on the same horizontal plane. The portion 43 is provided with a liquid outlet 431, and a plurality of the liquid outlets 431 are provided, and the plurality of liquid outlets 431 are equidistantly arranged from bottom to top. A liquid infusion tube 45 is connected to the dispersing portion 43, and one end of the liquid infusion tube 45 is connected to an external conveying device (the external conveying device can convey liquid pigment, which is not shown in the figure. The external conveying device is a prior art and will not be described in detail here). The liquid infusion tube 45 can convey liquid pigment into the dispersing portion 43, and through the plurality of liquid outlets 431 on the dispersing portion 43, the liquid pigment is evenly conveyed to different depths of the solvent to accelerate the mixing efficiency of the liquid pigment and the solvent.

[0036] Continue to refer Figures 1 to 6 As shown, the pushing part 44 is connected to the lifting part 42, and the blocking piece 46 is connected to the dispersing part 43. The blocking piece 46 is provided in plurality, and the plurality of blocking pieces 46 correspond one to one to the plurality of liquid outlets 431. The driving source 41 can drive the lifting part 42 to move downward. When the lifting part 42 moves downward, it can drive the pushing part 44 to push the blocking pieces 46 of corresponding heights one by one from top to bottom, so that the blocking pieces 46 block the liquid outlets 431 of corresponding heights until the bottom of the lifting part 42 contacts the upper surface of the solvent, thereby blocking the liquid outlets 431 leaking out of the solvent surface, thereby realizing the selection of the number of liquid outlets 431 to be opened from bottom to top according to the height of the solvent, and further accelerating the mixing efficiency of the liquid pigment and the solvent.

[0037] Continue to refer Figures 1 to 6As shown, a slope 441 is provided at the bottom of the pushing portion 44, and the blocking member 46 includes a blocking portion 461 and an elastic portion 462. A limiting slide groove is provided on the dispersing portion 43, and the blocking portion 461 is slidingly connected in the limiting slide groove on the dispersing portion 43. The elastic portion 462 is a spring, and the elastic portion 462 is located in the limiting slide groove, and the two ends of the elastic portion 462 are respectively connected to the blocking portion 461 and the inner wall of the limiting slide groove, and the length of the blocking portion 461 is greater than the length of the limiting slide groove, so that the blocking portion 461 can still block the limiting slide groove when moving, so as to prevent solvent or liquid pigment from entering the limiting slide groove.

[0038] In other embodiments, the limiting slide groove can also be set at an angle, so that when the pushing part 44 moves downward, it pushes the blocking part 461 to move upward and block the liquid outlet 431. After the pushing part 44 is separated from the blocking part 461, the blocking part 461 can be reset by its own gravity, and there is no need for the elastic part 462 to pull and reset.

[0039] Continue to refer Figures 1 to 6 As shown, a plurality of seals 47 are provided, and the plurality of seals 47 are respectively connected to the plurality of liquid outlets 431. The seals 47 can seal the liquid outlets 431. Before use, the dispersion part 43 is filled with liquid pigment in advance so that no air is retained in the dispersion part 43 extending into the solvent, so as to avoid that when the dispersion part 43 disperses the liquid pigment, the air in the dispersion part 43 enters the solvent, thereby affecting the mixing effect of the solvent and the liquid pigment. The seal 47 includes a sealing part 471 and an elastic part 472. The elastic part 472 is a built-in The telescopic rod of the spring, the second elastic part 472 is connected to the liquid outlet 431, and the sealing part 471 is connected to the telescopic end of the second elastic part 472. The liquid outlet 431 can be sealed by the sealing part 471. When the dispersion part 43 disperses the liquid pigment, the external conveying equipment conveys the liquid pigment into the dispersion part 43 through the infusion tube 45, so that the pressure of the liquid pigment inside the dispersion part 43 is increased, thereby pushing the sealing part 471 away from the liquid outlet 431 and stretching the second elastic part 472, thereby evenly conveying the liquid pigment to different depths of the solvent.

[0040] In other embodiments, the number of the dispersing parts 43 may be multiple, so as to respectively deliver different liquid pigments into the solvent in the container 2 .

[0041] like Figures 1 to 4 , Figures 7 to 9As shown, the lifting part 42 is circular, and the top of the lifting part 42 is provided with a mounting groove 1 421 and a mounting groove 2 424, and the lifting part 42 is provided with an airway 1 422 and an airway 2 423, the airway 1 422 and the airway 2 423 are connected, and the airway 2 423 is connected with the mounting groove 1 421, the dispersion part 43 is inserted in the mounting groove 1 421, and the pushing part 44 is connected in the mounting groove 1 421, and the separation mechanism 5 includes a driving source 3 51, an airbag 1 52, and an airbag Two 53 and airbag three 54, driving source three 51 is connected to the top of the lifting part 42, driving source three 51 is an air pump, driving source three 51 can supply gas to airway one 422 or extract the gas in airway one 422, airbag one 52 is ring-shaped, airbag one 52 is connected to the outer peripheral surface of the lifting part 42, airbag two 53 is connected in airway two 423, airbag three 54 is connected to the inner lower end of the mounting groove two 424, and airbag three 54 can seal the mounting groove two 424.

[0042] After the bottom of the lifting part 42 contacts the upper surface of the solvent, the airbag three 54 contacts the solvent and generates wrinkles, and the driving source three 51 is started to supply air to the airway one 422 to expand the airbag one 52 and the airbag two 53. The outer peripheral surface of the expanded airbag one 52 contacts the inner wall of the container 2, and the expanded airbag two 53 is filled into the installation groove one 421 to seal the installation groove one 421. At this time, under the action of the lifting part 42, the airbag one 52, the airbag two 53 and the airbag three 54, the air above the lifting part 42 can be mixed with the solvent. The solvent below the lifting part 42 is separated, thereby reducing the bubbles generated when the stirring mechanism 1 stirs the solvent, thereby enhancing the mixing effect of the solvent and the liquid pigment. When the dispersion part 43 transports the liquid pigment into the solvent, the amount of liquid below the lifting part 42 increases. At this time, the liquid below the lifting part 42 pushes the airbag three 54 upward to make the airbag three 54 bulge upward, thereby leaving enough space for the addition of liquid pigment, so as to avoid the increase of pressure in the solvent and the liquid pigment, which affects the mixing effect and mixing efficiency of the solvent and the liquid pigment.

[0043] The present invention also provides a stirring method of a paint stirring device, which comprises the following steps: S1: Start the stirring rod 14 to move downward, and drive the stirring blade 15 and the dispersion part 43 to extend into the container 2; Specifically, the dispersion part 43 is filled with liquid pigment in advance so that no air is left in the dispersion part 43 extending into the solvent, and the plurality of liquid outlets 431 are sealed by a plurality of sealing members 47 respectively, and the lifting member 12 is started to drive the driving member 13, the stirring rod 14 and the stirring blade 15 to move downward, so that the stirring rod 14, the stirring blade 15 and the dispersion part 43 extend into the containing barrel 2; The driving source 1 31 is started to drive the bidirectional screw 32 to rotate, and the bidirectional screw 32 drives the two clamping parts 33 to approach each other on the base 11 and clamp the container 2; S2: Start the lifting part 42 to move down to the upper surface of the solvent, and drive the pushing part 44 to push the blocking part 461 from top to bottom in sequence to block the liquid outlet 431 leaking out of the solvent surface; Specifically, the second driving source 41 is started to drive the lifting part 42 to move down to the upper surface of the solvent. When the lifting part 42 moves down, it drives the pushing part 44 to push the blocking part 461 from top to bottom in sequence, thereby blocking the liquid outlet 431 leaking out of the solvent surface; The driving source 3 51 is started to supply air into the air passage 1 422 to expand the airbag 1 52 and the airbag 2 53. The outer peripheral surface of the expanded airbag 1 52 contacts the inner wall of the container 2. The expanded airbag 2 53 fills the mounting groove 1 421 to seal the mounting groove 1 421. At this time, under the action of the lifting part 42, the airbag 1 52, the airbag 2 53 and the airbag 3 54, the air above the lifting part 42 can be separated from the solvent below the lifting part 42. S3: Start the stirring rod 14 to drive the stirring blade 15 to rotate to stir the solvent, and start the dispersing part 43 to transport the liquid pigment to different depths of the solvent through the liquid outlet 431 extending into the solvent.

[0044] Specifically, the driving member 13 is started to drive the stirring rod 14 to rotate, so that the stirring rod 14 drives the stirring blade 15 to stir the solvent, and the external conveying equipment is started to convey the liquid pigment into the dispersion part 43 through the infusion tube 45, and the liquid pigment is evenly conveyed to different depths of the solvent through the liquid outlet 431 on the dispersion part 43 extending into the solvent, and the liquid under the lifting part 42 pushes the airbag three 54 upward, so that the airbag three 54 bulges upward, thereby leaving enough space for the addition of liquid pigment.
