Description

Technical Field

[0001] The present invention relates to the technical field of paint mixing, and particularly to an automobile spray paint mixing and stirring device. Background Art

[0002] Automobile spray paint is a crucial part in the process of automobile manufacturing and maintenance. It not only provides an aesthetic appearance for the automobile, but also plays a protective role. Automobile spray paint includes ordinary paint, metallic paint, pearlescent paint and special types of paint.

[0003] During the processing of automobile spray paint, it is often necessary to mix liquid materials and powder materials. Among them, the stirring time should be sufficient. Generally, it is required that after adding each component and stirring for at least 15 minutes, then add another component for stirring, and so on until all components are fully stirred and mixed evenly. In the process of mixing paint by the existing automobile spray paint mixing and stirring device, most of them introduce different liquid materials into the mixing tank, and directly feed the powder materials above the liquid materials, and the stirring components in the device directly stir the liquid materials and powder materials;

[0004] However, since the powder materials are located above the liquid materials, the stirring components cannot directly stir the powder materials at the beginning. After the liquid materials are stirred for a period of time, the powder materials can enter the stirring range of the stirring components to achieve the mixing of the powder materials and the liquid materials. This stirring method is inconvenient for quickly mixing the powder materials, prolongs the stirring time of the paint, and moreover, when multiple powder materials need to be added, the stirring time of the paint needs to be increased correspondingly, seriously reducing the mixing speed of the paint, being inconvenient for quickly mixing the liquid materials and the powder materials, and reducing the working efficiency.

[0005] Therefore, it is necessary to provide an automobile spray paint mixing and stirring device, aiming to solve the above problems. Summary of the Invention

[0018] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0019] 1. In the present invention, when the switching component is in different states, correspondingly, when the switching component is in the first state, the stirring component stirs different liquid materials inside the mixing tank by cooperating with the rotating cylinder. When the switching component is in the second state, the stirring component efficiently mixes the liquid materials and powder materials inside the mixing tank by cooperating with the rotating cylinder, avoiding the drawback that the powder materials above the liquid materials cannot be quickly mixed, accelerating the mixing speed of the paint, and at the same time, the rotating cylinder turns up the paint located at the inner bottom of the mixing tank by driving the first scraper to rotate synchronously, avoiding the problem that the paint located at the inner bottom of the mixing tank cannot be well stirred. The first scraper scrapes the paint adhered to the inner wall of the mixing tank by driving the second scraper to rotate synchronously, facilitating the comprehensive and uniform mixing and stirring of the paint, avoiding the problems of color difference and unevenness of the paint, and improving the uniformity and comprehensiveness of the paint mixing;

[0020] 2. In the present invention, when the switching component is in the second state, the driven gear drives the transmission gear to rotate by meshing with the transmission gear and the transmission gear meshing with the second internal gear ring. The transmission gear drives the rotating disk to rotate synchronously by rotatably cooperating with the support ring and the second guide rod slidingly cooperating with the rotating disk. The rotating disk drives the powder materials thereon to rotate synchronously. The rotating disk reciprocates up and down in the vertical direction by the sliding cooperation of the sliding column and the guiding ring groove. The rotating disk drives the powder materials located in different feeding areas to vibrate by its own vibration. The powder materials fall through the through holes to the upper part of the liquid materials inside the mixing tank, realizing the comprehensive and uniform feeding of the powder materials, avoiding the powder materials being fed in a certain area inside the mixing tank, and facilitating the quick and uniform mixing of the powder materials and the liquid materials;

[0021] 3. In the present invention, during the process of the paint passing through the first through groove, the paint will move from the side with a larger cross-sectional size of the first through groove to the side with a smaller cross-sectional size of the first through groove, thereby accelerating the speed of the paint passing through the first through groove. During the process of the paint passing through the second through groove, the paint will move from the side with a smaller cross-sectional size of the second through groove to the side with a larger cross-sectional size of the second through groove, thereby decelerating the speed of the paint passing through the second through groove. By arranging the first through groove and the second through groove at intervals, different acceleration and deceleration treatments can be performed on the paint, improving the contact efficiency of different paints, accelerating the mixing efficiency, and facilitating the comprehensive and uniform mixing of the paint.

Detailed implementation manners

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0034] In an embodiment of the present invention, referring to Figure 1 - Figure 2 , an automobile paint mixing and stirring device includes a mixing tank 1 and an upper cover 2 arranged above the mixing tank 1. The upper part of the mixing tank 1 is respectively provided with a first liquid inlet pipe 11 and a second liquid inlet pipe 12. The bottom of the mixing tank 1 is provided with a liquid outlet pipe 13, and a solenoid valve 131 is arranged at the liquid outlet pipe 13. A rotating drum 3 is rotatably arranged in the mixing tank 1. A stirring assembly 4 for correspondingly stirring the paint is arranged between the rotating drum 3 and the upper cover 2. A material distributing assembly 6 is movably arranged inside the upper cover 2. A powder feeding pipe 21 corresponding to the material distributing assembly 6 is arranged at the top of the upper cover 2. A switching assembly 5 connecting the stirring assembly 4 and the material distributing assembly 6 is arranged inside the upper cover 2.

[0035] In this embodiment, the liquid material can be introduced into the mixing tank 1 through the first liquid inlet pipe 11 and the second liquid inlet pipe 12, and the powder material can be introduced onto the material distribution assembly 6 through the powder feeding pipe 21. When the switching assembly 5 is in the first state, the stirring assembly 4 stirs different liquid materials inside the mixing tank 1 by cooperating with the rotating drum 3. When the switching assembly 5 is in the second state, the stirring assembly 4 uniformly feeds the powder material through the cooperation of the switching assembly 5 and the material distribution assembly 6, so that the powder material is uniformly dispersed above the liquid material inside the mixing tank 1. The stirring assembly 4 efficiently mixes the liquid material and the powder material inside the mixing tank 1 by cooperating with the rotating drum 3, avoiding the drawback that the powder material above the liquid material cannot be quickly mixed, accelerating the mixing speed of the paint, and at the same time, the paint located at the bottom of the mixing tank 1 and the paint adhering to the inner wall of the mixing tank 1 can be mixed, improving the uniformity and comprehensiveness of the paint mixing. After the paint is mixed, the solenoid valve 131 is opened, and the mixed paint is discharged through the liquid outlet pipe 13, having the effects of efficient and comprehensive mixing, multiple stirring, flexible switching, uniform powder feeding, reliable structure, convenient operation, and simple and practical use;

[0036] Wherein, a screw cap 22 is provided on the powder feeding pipe 21. Through the setting of the screw cap 22, it can prevent external dust or sundries from entering the internal spaces of the mixing tank 1 and the upper cover 2 during the paint mixing process, improving the cleanliness of the paint.

[0037] In an embodiment of the present invention, refer to Figure 1 - Figure 4 and Figure 8 , the stirring assembly 4 includes a plurality of first scraping plates 41 circumferentially distributed at the bottom of the rotating drum 3. The bottom of the first scraping plate 41 is movably attached to the bottom of the mixing tank 1. One end of the first scraping plate 41 away from the rotating drum 3 is connected to a second scraping plate 42 that is movably attached to the inner wall of the mixing tank 1. A plurality of groups of stirring groups are axially and uniformly distributed at one end of the rotating drum 3 close to the first scraping plate 41. Each stirring group includes a plurality of connecting rods 44 circumferentially distributed on the rotating drum 3. The connecting rod 44 is a Z-shaped rod, and the connecting rod 44 is rotatably connected to the rotating drum 3. The outer end of the connecting rod 44 is connected to a stirring paddle 43, and the other end of the connecting rod 44 penetrates through the rotating drum 3 and is connected to a first bevel gear 45 movably arranged on the inner wall of the rotating drum 3. An activity rod 46 located inside the rotating drum 3 is rotatably arranged between the mixing tank 1 and the upper cover 2. A plurality of second bevel gears 47 meshing with the corresponding first bevel gears 45 are axially distributed on the activity rod 46. A driven gear 48 is provided on the outer wall of one end of the rotating drum 3 away from the first scraping plate 41, and a driving gear 49 meshing with the driven gear 48 is movably arranged inside the upper cover 2. The driving gear 49 is connected to a motor 410 installed on the upper cover 2.

[0038] In this embodiment, when the switching component 5 is in the second state, the position of the movable rod 46 is fixed and cannot rotate. The motor 410 drives the driving gear 49 to rotate. The driving gear 49 drives the rotating cylinder 3 to rotate synchronously by meshing with the driven gear 48. The rotating cylinder 3 drives a plurality of connecting rods 44 to rotate circumferentially around the movable rod 46. The connecting rods 44 drive the stirring paddles 43 to rotate synchronously. At the same time, since the first bevel gear 45 connected to one end of the connecting rod 44 meshes with the fixed second bevel gear 47, when the connecting rod 44 rotates circumferentially around the movable rod 46, the first bevel gear 45 drives the connecting rod 44 to rotate around the axis of the first bevel gear 45 by meshing with the second bevel gear 47, realizing the self-rotation of the connecting rod 44 and the circumferential rotation around the movable rod 46. The connecting rod 44 drives the stirring paddle 43 to rotate synchronously around the axis of the first bevel gear 45 by being connected to the stirring paddle 43. The stirring paddle 43 stirs the powder located above the liquid material into the liquid material by rotating in the vertical direction, thereby realizing the rotation of the stirring paddle 43 in different directions, realizing the rapid and uniform mixing of the powder and the liquid material, and avoiding the problem that the powder floats above the liquid material for a long time after feeding;

[0039] When the switching component 5 is in the first state, the position of the movable rod 46 is adjusted to an active state and the movable rod 46 moves synchronously with the rotating cylinder 3. The motor 410 drives the driving gear 49 to rotate. The driving gear 49 drives the rotating cylinder 3 to rotate synchronously by meshing with the driven gear 48. The rotating cylinder 3 drives the movable rod 46 to rotate synchronously through the cooperation of the switching component 5 and the movable rod 46, so that the second bevel gear 47 provided on the movable rod 46 rotates synchronously with the rotating cylinder 3, and the position of the first bevel gear 45 can be relatively positioned. The rotating cylinder 3 fixes the angles of the connecting rod 44 and the stirring paddle 43 by relatively fixing the position of the first bevel gear 45, and can realize the circumferential rotation of the connecting rod 44 and the stirring paddle 43 around the rotating cylinder 3, thereby quickly mixing different liquid materials;

[0040] In addition, the rotating cylinder 3 turns up the paint located at the inner bottom of the mixing tank 1 by driving the first scraper 41 to rotate synchronously, avoiding the problem that the paint located at the inner bottom of the mixing tank 1 cannot be stirred well. The first scraper 41 scrapes the paint adhering to the inner wall of the mixing tank 1 by driving the second scraper 42 to rotate synchronously, facilitating the comprehensive and uniform mixing and stirring of the paint, and avoiding the problems of color difference and unevenness of the paint;

[0041] Among them, the first scraping plate 41 and the second scraping plate 42 are both inclined plates. A number of first through grooves 431 and second through grooves 432 are distributed at intervals on the stirring paddle 43. The top view of the first through groove 431 is an isosceles trapezoid, and the top view of the second through groove 432 is an inverted isosceles trapezoid. During the process of the paint passing through the first through groove 431, the paint will move from the side with a larger cross-sectional size of the first through groove 431 to the side with a smaller cross-sectional size of the first through groove 431, thereby accelerating the speed of the paint passing through the first through groove 431. During the process of the paint passing through the second through groove 432, the paint will move from the side with a smaller cross-sectional size of the second through groove 432 to the side with a larger cross-sectional size of the second through groove 432, thereby decelerating the speed of the paint passing through the second through groove 432. By arranging the first through grooves 431 and the second through grooves 432 at intervals, different acceleration and deceleration treatments can be performed on the paint, improving the contact efficiency of different paints, accelerating the mixing efficiency, and facilitating the comprehensive and uniform mixing of the paint.

[0042] In an embodiment of the present invention, referring to Figure 1 - Figure 7 , the switching assembly 5 includes a first internal gear ring 51 fixedly arranged at the inner top of the rotating cylinder 3. A guide cylinder 54 is fixedly installed at the inner top of the upper cover 2 and is arranged outside the movable rod 46. A lifting plate 56 is movably arranged inside the upper cover 2. One end of the lifting plate 56 is connected with a connecting ring 55. A sliding cylinder 53 located between the movable rod 46 and the guide cylinder 54 is rotatably arranged inside the connecting ring 55. The outer wall of the sliding cylinder 53 is slidably matched with the inner wall of the guide cylinder 54, and the inner wall of the sliding cylinder 53 is slidably matched with the movable rod 46. One end of the sliding cylinder 53 close to the rotating cylinder 3 is connected with an external gear ring 52 sleeved outside the movable rod 46. The external gear ring 52 is movably engaged with the first internal gear ring 51. A first guide rod 57 slidably matched with the upper cover 2 is installed on the lifting plate 56. An electric cylinder 58 connected with the lifting plate 56 is installed on the upper cover 2. One end of the lifting plate 56 far from the connecting ring 55 is rotatably connected with a transmission gear 59. The transmission gear 59 is movably engaged with the driven gear 48;

[0043] The material distribution assembly 6 includes a second internal gear ring 61 movably arranged inside the upper cover 2. The second internal gear ring 61 is movably engaged with the transmission gear 59. The second internal gear ring 61 is rotatably matched with a support ring 68 arranged on the inner wall of the upper cover 2. A rotating disk 63 sleeved outside the rotating cylinder 3 is movably arranged inside the upper cover 2. A number of partition plates 64 are circumferentially distributed on the inner side of the rotating disk 63. A number of through holes 65 are distributed at the bottom of the rotating disk 63. A number of second guide rods 62 connected with the second internal gear ring 61 are slidably arranged on the rotating disk 63. A guide ring groove 67 is arranged on the inner wall of the upper cover 2. A number of sliding columns 66 are slidably arranged in the guide ring groove 67. The sliding columns 66 are connected with the outer wall of the rotating disk 63.

[0044] In this embodiment, when the switching component 5 is in the second state, the sliding cylinder 53 is engaged with the guiding cylinder 54, the outer gear ring 52 is away from the first inner gear ring 51, the lifting plate 56 is at the highest point, the transmission gear 59 is engaged with the second inner gear ring 61, and the transmission gear 59 is engaged with the driven gear 48. At this time, the position of the movable rod 46 is fixed, the motor 410 drives the driving gear 49 to rotate, and the driving gear 49 drives the rotating cylinder 3 to rotate by engaging with the driven gear 48. Since the position of the movable rod 46 is fixed, the first bevel gear 45 drives the connecting rod 44 to rotate around the axis of the first bevel gear 45 by engaging with the second bevel gear 47, so that the self-rotation of the connecting rod 44 and the circumferential rotation around the movable rod 46 can be realized, thereby realizing the rotation of the stirring paddle 43 in different directions;

[0045] Meanwhile, the driven gear 48 drives the transmission gear 59 to rotate by engaging with the transmission gear 59 and the transmission gear 59 being engaged with the second inner gear ring 61. The transmission gear 59 drives the rotating disk 63 to rotate synchronously by rotatably cooperating with the support ring 68 and the second guide rod 62 slidingly cooperating with the rotating disk 63. The rotating disk 63 drives the powder thereon to rotate synchronously. The rotating disk 63 reciprocates up and down in the vertical direction by slidingly cooperating the sliding column 66 with the guide ring groove 67. Among them, the ascending stage of the rotating disk 63 is gradually inclined upward, and the descending stage of the rotating disk 63 is vertically downward, so that the shaking of the rotating disk 63 during rotation can be realized. The plurality of partition plates 64 divide the inner space of the rotating disk 63 into several blanking areas. The rotating disk 63 drives the powder located in different blanking areas to shake by its own shaking manner. The powder falls through the through hole 65 to the upper part of the liquid material inside the mixing tank 1, realizing the comprehensive and uniform blanking of the powder, avoiding the powder feeding in a certain area inside the mixing tank 1, and facilitating the rapid and uniform mixing of the powder and the liquid material;

[0046] When the switching component 5 is in the first state, the electric cylinder 58 extends downward and pushes the lifting plate 56 to move downward by connecting with the lifting plate 56 and the first guide rod 57 slidingly cooperating with the upper cover 2. The lifting plate 56 drives the connecting ring 55 and the transmission gear 59 to move downward synchronously, releasing the engagement between the transmission gear 59 and the driven gear 48 and between the transmission gear 59 and the second inner gear ring 61, so that the rotating disk 63 stops rotating;

[0047] Meanwhile, the connecting ring 55 drives the sliding cylinder 53 to move downward by means of rotational connection with the sliding cylinder 53, releases the engagement between the sliding cylinder 53 and the guiding cylinder 54, and enables the outer gear ring 52 to engage with the first inner gear ring 51. The synchronous rotation between the rotating cylinder 3 and the movable rod 46 is achieved by the engagement between the first inner gear ring 51 and the outer gear ring 52 and the sliding fit between the sliding cylinder 53 and the movable rod 46. The motor 410 drives the driving gear 49 to rotate, and the driving gear 49 drives the rotating cylinder 3 to rotate synchronously by engaging with the driven gear 48. The rotating cylinder 3 drives the movable rod 46 to rotate synchronously through the cooperation of the switching assembly 5 and the movable rod 46, so that the second bevel gear 47 provided on the movable rod 46 rotates synchronously with the rotating cylinder 3, and the position of the first bevel gear 45 can be relatively positioned. The rotating cylinder 3 fixes the angles of the connecting rod 44 and the stirring paddle 43 by relatively fixing the position of the first bevel gear 45, and the connecting rod 44 and the stirring paddle 43 can rotate circumferentially around the rotating cylinder 3, so as to quickly mix different liquid materials;

[0048] Wherein, the height of the second inner gear ring 61 is the same as that of the driven gear 48, the guiding ring groove 67 is provided as an annular wavy groove, the guiding ring groove 67 includes a plurality of rising segments and corresponding falling segments, and the number of the rising segments is the same as the number of the sliding columns 66. Through the sliding fit between the sliding columns 66 and the guiding ring groove 67, the rotating disk 63 can be stably supported. A clamping strip is provided inside the guiding cylinder 54, a clamping groove matched with the clamping strip is provided on the outer side wall of the sliding cylinder 53, a sliding groove is provided on the outer wall of the movable rod 46, and a sliding strip slidably matched with the sliding groove is provided inside the sliding cylinder 53. Through the cooperation of the clamping strip and the clamping groove, the engagement between the sliding cylinder 53 and the guiding cylinder 54 can be achieved. Through the cooperation of the sliding groove and the sliding strip and the connection between the sliding cylinder 53 and the outer gear ring 52, the synchronous rotation between the movable rod 46 and the outer gear ring 52 can be achieved, so as to achieve the synchronous rotation between the movable rod 46 and the rotating cylinder 3.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
