[0002] Coating engineering is a systematic project of forming a protective or decorative coating on the surface of an object through paint application, and is widely used in the fields of building, industry, ship, automobile, furniture, etc. The core value of coating engineering lies in corrosion protection, decoration and functional enhancement, etc. A complete coating engineering not only includes the spraying operation itself, but also covers multiple links such as pretreatment, coating, post-treatment and quality control. Before the coating engineering is carried out, suitable paint needs to be prepared, and the paint is the material basis and technical core of the coating engineering, and its performance directly determines the coating effect, engineering life and cost benefit.

[0003] In the coating engineering, the preparation process of part of the paint involves putting the powder raw material into the liquid for stirring and mixing, and then making the paint with excellent quality. This process needs to use a paint mixing device, which generally includes a container for containing liquid and a stirring shaft provided with blades. In use, the powder raw material is put into the container, and the stirring shaft is rotated to uniformly mix the powder raw material and the liquid.

[0004] For example, the patent with the authorized announcement number CN112452236B discloses a stirring device for producing powder paint, which includes a stirring barrel, a stirring shaft extending upward and downward and extending into the stirring barrel, stirring blades for stirring raw materials are fixed on the stirring shaft, and a sanding body connected with the stirring shaft and capable of rotating with the stirring shaft is also connected to the stirring shaft.

[0005] The existing stirring device generally sets an inlet for feeding powder at the top of the stirring barrel, and the inlet is generally staggered with the stirring shaft. In this way, part of the powder entering the stirring barrel is distributed in the area close to the inner wall of the stirring barrel, and this part of the powder is far away from the stirring shaft and receives less shear force, so it is difficult to disperse and is easy to form hard lumps. The undissolved lumps may also settle at the edge of the stirring barrel and cannot participate in dissolution and stirring, resulting in uneven mixing of the powder and the liquid and affecting the quality of the paint product. SUMMARY

[0006] The present application provides a paint mixing device to solve the technical problem of uneven mixing of the existing paint mixing and stirring device.

[0007] To solve the above problems, the paint mixing device provided by the present application adopts the following technical scheme:

[0058] As shown in the drawings, Figure 3 , Figure 4 , Figure 5 The side of the grid plate one 28 facing the center of the tank body 1 is connected with a rod member 19 extending along the radial direction of the tank body 1, and the side of the grid plate two 25 facing the center of the tank body 1 is connected with a sleeve 18 extending along the radial direction of the tank body 1, the sleeve 18 is slidably sleeved on the outer side of the rod member 19, and the end of the sleeve 18 away from the grid plate two 25 is closed.

[0059] The bottom of the stirring fork 23 is slidably sleeved on the outer side of the sleeve 18, the stirring fork 23 and the grid plate two 25 are connected with an elastic member three 26, and the stirring fork 23 is further connected with an arc-shaped baffle 27, the arc-shaped baffle 27 is located above the elastic member three 26 and is used for preventing the falling powder from being clamped into the elastic member three 26. The elastic member three 26 plays a buffering role to prevent the stirring fork 23 from colliding violently with the storage box 10 when moving to the end of the discharging channel 241.

[0060] As Figure 3 shown in the figure, the elastic member one 17 is connected between the sleeve 18 and the rod member 19, and the elastic member one 17 is a compression spring capable of extending radially along the tank body 1.

[0061] As Figure 5 , Figure 8 , Figure 9 , Figure 10 shown in the figure, the locking member includes a support body 30 and two movable clamping blocks 29, the support body 30 is fixedly connected to the side wall of the grid plate one 28 facing the center of the tank body 1, and the two movable clamping blocks 29 are arranged on both sides of the support body 30 and can slide on the support body 30, and a gap is provided between the two movable clamping blocks 29 and the grid plate one 28 in the radial direction of the tank body 1. The elastic member two 16 is connected between the movable clamping block 29 and the support body 30, the elastic member two 16 is a compression spring, and the movable clamping block 29 is kept in a state of extending to the outside of the support body 30 under the action of the elastic member two 16.

The side of the movable clamping block 29 facing the center of the tank body 1 is provided with a pushing inclined surface 291, and the grid plate two 25 is provided with a through hole 254 extending in the radial direction of the tank body 1 corresponding to the support body 30. When the grid plate one 28 and the grid plate two 25 are close to each other, the grid plate two 25 can push the movable clamping block 29 into the inside of the support body 30 through the pushing inclined surface 291, so that the support body 30 is arranged in the through hole 254. After the grid plate two 25 moves to the gap between the movable clamping block 29 and the grid plate one 28, the movable clamping block 29 is reset to extend to the outside of the support body 30, thereby blocking the grid plate two 25 and locking the grid plate one 28 and the grid plate two 25.

[0062] As Figure 4 , Figure 5 shown in the figure, the unlocking member is installed at the bottom of the movable part 202, and the unlocking member is located on the moving path of the locking member. The unlocking member includes a connecting block 20 connected to the movable part 202 and two unlocking columns 21 arranged at intervals and connected to the bottom of the connecting block 20. The two unlocking columns 21 are provided with two arc unlocking surfaces on the side close to each other, and the two arc unlocking surfaces correspond to the two pushing inclined surfaces 291 respectively. When the locking member moves to contact the unlocking member, the two arc unlocking surfaces on the two unlocking columns 21 push the two movable clamping blocks 29 through the two pushing inclined surfaces 291 respectively, so that the movable clamping blocks 29 are inserted into the support body 30, thereby realizing the unlocking of the grid plate one 28 and the grid plate two 25. After the grid plate one 28 and the grid plate two 25 are unlocked, the grid plate one 28 is elastically reset towards the inside of the tank body 1 under the elastic action of the elastic member one 17.

[0063] The sleeve 18 is slidably arranged in the connecting block 20, and the connecting block 20 guides the sleeve 18 to make the sliding of the sleeve 18 more stable.

[0064] As Figures 1-4As shown, the rotating mechanism comprises a rotating motor 4 fixedly installed on the support plate 301 and a gear set comprising a driving gear 6 and a driven gear 7, the driving gear 6 being fixedly connected to the output shaft of the rotating motor 4, and the driven gear 7 being fixedly sleeved on the outer side of the sleeve 8, the rotating motor 4 drives the driving gear 6 to rotate, the driving gear 6 drives the driven gear 7 to rotate, and further drives the movable part 202 to rotate.

[0065] The driving mechanism comprises a driving motor 5, a main shaft 9, a rotating body and a guide rail 15. The driving motor 5 is fixedly installed on the support plate 301, the main shaft 9 is arranged in the sleeve 8, the main shaft 9 is fixedly connected to the output shaft of the driving motor 5, the bottom end of the main shaft 9 extends below the movable part 202, the rotating body comprises two rotating plates 13 and a connecting shaft 14, the rotating plates 13 are circular, the two rotating plates 13 are arranged in a coaxial manner, the connecting shaft 14 is connected between the two rotating plates 13 and is offset from the central axis of the rotating plates 13, and the upper rotating plate 13 is coaxially connected to the bottom end of the main shaft 9. The guide rail 15 is in a strip shape, and a strip-shaped sliding hole 151 is arranged in the guide rail 15, the guide rail 15 is vertically connected to one end of the sleeve 18 away from the second grid plate 25, and the connecting shaft 14 is arranged in the strip-shaped sliding hole 151.

[0066] When the driving motor 5 rotates, the rotating body rotates, the connecting shaft 14 revolves around the central axis of the rotating body, the guide rail 15 moves along the tank body 1 in a radial direction, and further the sleeve 18 moves along the tank body 1 in a radial direction.

[0067] The stirring shaft 11 is arranged in the tank body 1, coaxially connected to the bottom of the lower rotating plate 13, and the bottom end of the stirring shaft 11 is provided with stirring blades 12.

[0068] The rotating speed of the rotating body is higher than that of the movable part 202, and the rotating body and the movable part 202 have a rotating speed difference, so that the rotating body can rotate relative to the movable part 202, thereby ensuring that the guide rail 15 can be pulled by the connecting shaft 14 to move along the tank body 1 in a radial direction.

[0069] In use, a set amount of water is injected into the tank 1 through the observation window 203, and an appropriate amount of powder is loaded into the storage box 10. The rotating motor 4 and the driving motor 5 are started. The rotating motor 4 drives the movable part 202 and the storage box 10 and the push plate group connected to the movable part 202 to revolve around the center of the tank 1. The driving motor 5 drives the rotating body to rotate, which in turn drives the stirring shaft 11 to rotate and drives the sleeve 18 to move back and forth along the radial direction of the tank 1, and further drives the push plate group to move back and forth along the radial direction of the tank 1. The rotating body rotates one revolution, and the push plate group moves back and forth along the radial direction of the tank 1 once. When the sleeve 18 moves, it drives the prong 23 to move back and forth along the radial direction of the tank 1. The prong teeth push the powder in the storage box 10, promoting the powder to fall from the discharge channel 241 into the tank 1. During the movement of the prong teeth, the caked powder in the storage box 10 can also be screened out. When the prong teeth move to the end of the discharge channel 241, the prong teeth cooperate with the inner wall of the storage box 10 to crush the caked powder. After the caked powder is crushed, it can fall smoothly through the discharge channel 241.

[0070] During the movement of the sleeve 18 along the radial direction of the tank 1, the push plate group is also driven to move back and forth along the radial direction of the tank 1. During the movement of the push plate group from the side wall of the tank 1 towards the stirring shaft 11, the arc-shaped solid plate formed by the first grid plate 28 and the second grid plate 25 can push the powder falling into the tank 1 from the inlet towards the stirring shaft 11, making the powder closer to the rotation center, enhancing the shearing effect on the powder, and making the mixing of the powder and liquid more uniform. When the push plate group moves to the contact between the locking member and the unlocking member, the unlocking column 21 pushes the movable clamping block 29 into the support body 30 through the pushing slope 291. At this time, the first grid plate 28 moves towards the inner wall of the tank 1 under the action of the first elastic member 17. During the movement of the first grid plate 28, the caked powder in the tank 1 is collected. When the first grid plate 28 contacts the inner wall of the tank 1, it cooperates with the inner wall of the tank 1 to crush the collected caked powder. After the first grid plate 28 is attached to the inner wall of the tank 1, it rotates against the inner wall of the tank 1, scraping off the powder attached to the inner wall of the tank 1, so that this part of the powder participates in the mixing.

[0071] After the first grid plate 28 is reset, the second grid plate 25 is reset towards the inner wall of the tank 1 under the drive of the sleeve 18. During this process, the second grid plate 25 continues to collect the caked powder in the tank 1, and when it moves to contact the inner wall of the tank 1, it cooperates with the inner wall of the tank 1 and the first grid plate 28 to crush the caked powder. Since the second grid plate 25 can cooperate with the first grid plate 28 to shear the caked powder at this time, the caked powder is more easily broken. Subsequently, the second grid plate 25 pushes the movable clamping block 29 into the support body 30 through the pushing slope 291, so that the movable clamping block 29 is clamped between the movable clamping block 29 and the first grid plate 28, and the first grid plate 28 and the second grid plate 25 are again in the locked state.

[0072] The subsequent continues to repeat the above steps, and the reciprocating movement of the push plate group pushes the powder to the rotating center, and the caked powder is broken by extrusion, so that the powder fully participates in the mixing.

[0073] The application can crush the caked powder in the storage box 10, and also can break the caked powder entering the tank 1, so that the powder can more fully participate in the mixing with the liquid. The push plate group in the application can also push the powder to the rotating center, enhance the shear effect of the stirring process on the powder, and make the powder and the liquid mix more uniformly. The driving mechanism can drive the stirring shaft 11 to rotate and drive the push plate group to move at the same time, which can save power elements and simplify the equipment structure.
