DETAILED DESCRIPTION

[0044] The application will be further described in detail below with specific examples and in conjunction with the drawings. EMBODIMENT

[0045] Referring to Figures 1 to 12 The embodiment of the application discloses a paint mixing machine, which comprises a rack 100, a weight sensor (not shown in the figure), a mixing container (not shown in the figure), a plurality of paint storage assemblies 300, a control assembly 400 and a blocking assembly 500. The weight sensor is installed at the lower end of the mixing container and is used for measuring and recording the weight of the mixing container in real time. The rotating seat 200 is installed on the rack 100 and is used for driving the plurality of paint storage assemblies 300 to pass through the mixing container in turn. The control assembly 400 is used for sending the paint in the paint storage assembly 300 into the mixing container, and the blocking assembly 500 is used for moving to the position between the paint storage assembly 300 and the mixing container in time when enough paint in the paint storage assembly 300 falls into the mixing container, so as to avoid the excess paint from falling into the mixing container.

[0046] The paint mixing machine disclosed by the embodiment can accurately measure the input amount of various paints through the weight sensor, and meanwhile, can effectively avoid the excess paint from falling into the mixing container through the blocking assembly 500, so that the proportion of the various paints obtained in the mixing container meets the regulation in the specification, and the adjustment mode is simpler and more accurate than manual adjustment.

[0047] Referring to Figures 1 to 3 The rack 100 is provided with the placing platform 110 and the supporting platform 120, the weight sensor is installed on the placing platform 110, and the blocking assembly 500 is installed on the supporting platform 120.

[0048] The mixing container is detachably installed on the placing platform 110, and when the mixing container is placed on the placing platform 110, the weight sensor can directly measure the weight of the mixing container.

[0049] Referring toFigure 4 The rotating seat 200 is rotationally connected with the frame 100, and a plurality of first installation stations 210 and a plurality of second installation stations 220 are arranged on the rotating seat 200, and the plurality of first installation stations 210 and the plurality of second installation stations 220 are alternately arranged along the circumference of the rotating seat 200.

[0050] A plurality of paint storage assemblies 300 are arranged along the circumference of the rotating seat 200, and each of the plurality of paint storage assemblies 300 comprises at least one first storage container 310 and one second storage container 320, the discharge port of the first storage container 310 is larger than that of the second storage container 320, the first storage container 310 and the second storage container 320 are arranged along the circumference of the rotating seat 200, and the first storage container 310 is located in front of the second storage container 320. The first storage container 310 is installed in the first installation station 210, and the second storage container 320 is installed in the second installation station 220. The first storage container 310 and the second storage container 320 can be arranged in the shape of a syringe, and the liquid in the container can be pushed out by a push rod.

[0051] Referring to Figure 5 The control assembly 400 comprises a mounting seat 410, a lead screw 420, a control tab 430 and a servo motor 440. The mounting seat 410 is installed on the frame 100, the lead screw 420 is rotationally connected with the mounting seat 410, and the lead screw 420 is arranged along the height direction of the frame 100. The control tab 430 is threadedly connected with the lead screw 420, and the control tab 430 is slidingly connected with the mounting seat 410. When the control tab 430 moves downward, it can cooperate with the push rod to send the paint in the paint storage assembly 300 into the mixing container. The servo motor 440 is installed on the mounting seat 410, and the servo motor 440 is drivingly connected with the lead screw 420.

[0052] When the paint is sent from the paint storage assembly 300 into the mixing container, the paint gradually drips from the paint storage assembly 300 into the mixing container. Although the dripping speed of the paint gradually decreases as more and more paint enters the mixing container, when the final paint reaches the preset quality, there may still be one or more drops of paint that have been discharged from the paint storage assembly 300 without entering the mixing container. At this time, if the paint in the air continues to enter the mixing container, it may cause the amount of paint in the mixing container to be too large. In order to avoid the above situation, the paint mixing machine disclosed in the embodiment is designed with a blocking assembly 500, and the blocking assembly 500 is installed on the frame 100. When the weight sensor reaches the preset value, the blocking assembly 500 moves to between the mixing container and the paint storage assembly 300 to prevent excess paint from entering the mixing container.

[0053] Referring to Figures 6 to 12The blocking assembly 500 comprises a blocking plate 501, a scraping plate 502, a first control block 507, a second control block 508, a third control block 509, a fourth control block 510, a first guide rail 503, a second guide rail 504, a first sliding block 505 and a second sliding block 506.

[0054] The blocking plate 501 comprises a bottom wall 5011 and a peripheral wall 5012 arranged along the periphery of the bottom wall 5011. The bottom wall 5011 is slidably connected to the support platform 120, and the placement platform 110 is located on the sliding path of the bottom wall 5011. When the bottom wall 5011 moves, it can intervene between the placement platform 110 and the paint storage assembly 300 or leave the range between them. The scraping plate 502 is slidably connected to the rack 100, and the blocking plate 501 is located on the sliding path of the scraping plate 502. The scraping plate 502 is used to scrape the paint on the blocking plate 501, so as to avoid the paint from overflowing the peripheral wall 5012 and dripping into the mixing container due to excessive accumulation on the blocking plate 501.

[0055] Referring to Figures 8 to 12 The first control block 507, the second control block 508, the third control block 509 and the fourth control block 510 are used to control the position of the scraping plate 502, so that when the blocking plate 501 moves towards the placement platform 110, the scraping plate 502 can abut against the blocking plate 501 to scrape the paint away from one end of the blocking plate 501 away from the placement platform 110; and when the blocking plate 501 moves away from the placement platform 110, the scraping plate 502 can quickly lift up, thereby avoiding the paint on the blocking plate 501 from being scraped into the mixing container.

[0056] Specifically, the first control block 507 and the second control block 508 are respectively installed on the opposite sides of the peripheral wall 5012, and the scraping plate 502 is located between the first control block 507 and the second control block 508. The first control block 507 is located at one end of the bottom wall 5011 close to the placement platform 110. The third control block 509 and the fourth control block 510 are both installed on the scraping plate 502, and the third control block 509 and the fourth control block 510 are respectively located on the two sides of the scraping plate 502. When the blocking plate 501 moves towards the placement platform 110, the third control block 509 cooperates with the first control block 507 to make the scraping plate 502 move downward along the height direction of the rack 100 and contact the blocking plate 501; when the blocking plate 501 moves away from the placement platform 110, the fourth control block 510 cooperates with the second control block 508 to make the scraping plate 502 move upward along the height direction of the rack 100 and separate from the blocking plate 501.

[0057] The first guide rail 503, the second guide rail 504, the first sliding block 505 and the second sliding block 506 are used for supporting and limiting the scraper 502, so that the scraper 502 can be in contact with the baffle 501 at all times when the baffle 501 moves towards the placing platform 110, and the scraper 502 can be above the baffle 501 at all times when the baffle 501 moves away from the placing platform 110.

[0058] Specifically, the first guide rail 503 and the second guide rail 504 are both mounted on the peripheral wall 5012 of the baffle 501, and are arranged in the height direction of the baffle 501, and are arranged in parallel, and are parallel to the sliding direction of the baffle 501. The first sliding block 505 and the second sliding block 506 are both mounted on the side wall of the scraper 502, and are arranged in the height direction of the scraper 502. When the scraper 502 is in abutment with the bottom wall 5011, the first sliding block 505 can be in sliding cooperation with the first guide rail 503; when the scraper 502 is lifted upwards under the cooperation of the fourth control block 510 and the second control block 508, the second sliding block 506 can be in sliding cooperation with the second guide rail 504.

[0059] Referring to Figure 8 and Figures 10 to 12 In the embodiment, the lengths of the first guide rail 503 and the second guide rail 504 are limited, and the length of the first guide rail 503 is less than the distance between the first control block 507 and the second control block 508, and the length of the second guide rail 504 is equal to the length of the first guide rail 503.

[0060] In the embodiment, the positions of the first guide rail 503, the second guide rail 504, the first sliding block 505 and the second sliding block 506 are also limited, and the interval distance between the first sliding block 505 and the second sliding block 506 is less than the interval distance between the first guide rail 503 and the second guide rail 504, and the difference between the interval distance between the first sliding block 505 and the second sliding block 506 and the interval distance between the first guide rail 503 and the second guide rail 504 is equal to the height of the first control block 507.

[0061] Based on the above settings, referring to Figures 10 to 12 When the baffle 501 is at the position farthest from the placing platform 110, the baffle 501 is in abutment with the baffle 501 under the limitation of the first control block 507 and the third control block 509, and at this time the first sliding block 505 is aligned with the first guide rail 503, but at this time the first sliding block 505 has not yet cooperated with the first guide rail 503. When the baffle 501 moves towards the placing platform 110, the baffle 501 will drive the first guide rail 503 to move to cooperate with the first sliding block 505, so as to ensure that the scraper 502 is always in abutment with the baffle 501.

[0062] Referring to Figure 12 When the baffle 501 moves to above the placing platform 110, the scraper 502 is lifted and separated from the baffle 501 by cooperation of the second control block 508 and the fourth control block 510, the second sliding block 506 is aligned with the second guide rail 504 at this time, and the second sliding block 506 and the second guide rail 504 have not yet cooperated at this time. In order to avoid that the scraper 502 directly falls due to gravity when the baffle 501 moves, a spring (not shown in the figure) can be additionally arranged between the scraper 502 and the rack 100, the spring enables the scraper 502 to have a tendency to move upward, and in turn can ensure that the scraper 502 will not fall when the baffle 501 moves to the right, so as to ensure that the second sliding block 506 can cooperate with the second guide rail 504.

[0063] Referring to Figure 10 When the baffle 501 moves to the right to enable the first control block 507 and the third control block 509 to cooperate, the scraper 502 will move downward to form abutment with the baffle 501 under cooperation of the first control block 507 and the third control block 509, and the first sliding block 505 is aligned with the first guide rail 503.

[0064] The embodiment of the application further discloses a paint mixing method based on the paint mixer.

[0065] Step one: wash and dry the mixing container and place it on the placing bottle body;

[0066] Step two: sequentially set parameters of the weight of various colors of paint, and then sequentially pour different colors of paint into the paint storage assembly 300;

[0067] Step three: extrude the paint storage assembly 300 by using the control assembly 400 to enable the paint in the paint storage assembly 300 to enter the mixing container, in the process, the pressure of the control assembly 400 on the paint storage assembly 300 changes in a stepped manner, when the weight of the paint in the mixing container increases by M1, the pressure of the control assembly 400 on the paint storage assembly 300 is adjusted from P1 to P2, when the weight of the paint in the mixing container increases by M2, the pressure of the control assembly 400 on the paint storage assembly 300 is adjusted from P2 to P3, until the weight sensor detects that the weight of the paint in the mixing container reaches a preset weight, the blocking assembly 500 immediately moves to between the paint storage assembly 300 and the mixing container;

[0068] Step four: rotate the seat 200 by a certain angle to enable the next paint storage assembly 300 to move above the mixing container, and then repeat step three;

[0069] Step five: repeat step four until all the paint is sent into the mixing container in a certain amount, and finally perform stirring.

[0070] The paint mixing method disclosed in the embodiment can accurately measure the input amount of various paints through the weight sensor, and meanwhile, the excess paint can be effectively avoided from falling into the mixing container by using the material blocking assembly 500, so that the proportion of the various paints obtained in the mixing container meets the specification in the specification book, and the mixing mode is simpler and more accurate than manual mixing.

[0071] The preferred embodiments of the present application have been described above, but the present application is not limited to the above. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
