Description

Technical Field

[0001] The invention relates to the technical field of color paint production, and in particular to a solvent-based color paint mixing device and method. Background Art

[0002] Solvent-based paint is a kind of paint that uses organic solvents as diluents. It contains pigments, resins, solvents and other additives. Solvent-based paint will leave a strong and colorful paint film during the coating process. Solvent-based paint is widely used in architectural decoration, furniture manufacturing and automobile repair. Solvent-based paint is not a ready-made product. Generally, it needs to be mixed with multiple materials before use. After the mixing is completed, the various materials need to be evenly mixed by stirring.

[0003] The existing mixing methods are mostly to thoroughly mix various materials through high-speed dispersers or powerful stirrers. Although the above machines can effectively mix the solvent-based paint ratio materials, when discharging the mixed solvent-based paint, the solvent-based paint is basically discharged by opening the discharge valve, or the solvent-based paint is discharged by pouring. Solvent-based paint has a certain viscosity. The discharge efficiency is relatively slow if the solvent-based paint is discharged only by gravity and flow inertia, and the residual amount of solvent-based paint in the mixing machine will increase. This will not only affect the discharge and use of solvent-based paint and reduce the efficiency of solvent-based paint production, but also be difficult to clean the mixing machine and affect the subsequent production of solvent-based paint.

A screw rod 232 with a vertical axis is threadedly connected to one of the movable support plates 234.

[0044] See also Figure 2 and Figure 3 The center of the cross 2115 is provided with a through hole for the rack bar 2111 to pass through, and guide blocks 2116 are symmetrically fixedly connected in the through hole, and two guide blocks 2116 are respectively slidably connected to the two sides of the rack bar 2111. In specific operation, the through hole is used to avoid interference with the movement of the rack bar 2111. By setting the guide blocks 2116, the limit force points of the rack bar 2111 are increased to ensure the stable movement of the rack bar 2111 up and down.

[0045] See also Figure 2 , Figure 3 and Figure 4 The driving assembly 22 includes a gear ring 223 fixedly connected to the outside of the outer cylinder 212, and a gear 222 is meshedly connected to the outer periphery of the gear ring 223.

[0047] See also Figure 1 and Figure 6The discharge control assembly 28 includes a fixed sleeve 282 fixedly connected to the bottom center of the mixing tank 1, a rotating sleeve 283 is rotatably connected inside the fixed sleeve 282, the upper ends of the fixed sleeve 282 and the rotating sleeve 283 are both closed and are provided with a plurality of extrusion holes 281 equidistantly arranged around the circumference, a screen is installed in the extrusion hole 281 (the screen is not shown in the diagram), the lower ends of the fixed sleeve 282 and the rotating sleeve 283 are both open, and a rotating component 284 for controlling the rotation of the rotating sleeve 283 is provided outside.

[0048] See also Figure 1 , Figure 2 and Figure 6 The rotating component 284 includes a second gear ring 2843 fixedly connected to the outside of the lower side of the rotating sleeve 283. The second gear ring 2843 is located outside the fixed sleeve 282. The outer periphery of the second gear ring 2843 is meshed with a rack 2841.

When the rotating sleeve 283 rotates, the extrusion hole 281 on it will overlap with the extrusion hole 281 on the fixed sleeve 282. Under the extrusion of the complete circular plate structure assembled by the assembling leaves 26, the solvent-based paint is discharged from the extrusion hole 281 that is interconnected from top to bottom. When the extrusion holes 281 on the rotating sleeve 283 and the fixed sleeve 282 are not interconnected, the discharge of the solvent-based paint can be blocked; by setting a screen, the solvent-based paint can be filtered when the solvent-based paint is discharged, thereby improving the fineness of the solvent-based paint. While the complete circular plate structure assembled by the assembling leaves 26 moves downward to implement extrusion discharge, the circular plate structure also scrapes the inner wall of the mixing tank 1, which not only realizes the cleaning of the inner wall of the mixing tank 1, but also helps to increase the discharge amount of the solvent-based paint.

[0050] See also Figure 3 , Figure 4 and Figure 5 The assembling leaf 26 is fixedly connected with a mounting bar 27 , and the upper side of the mounting bar 27 is fixedly connected with a plurality of broken line stirring bars 25 extending in the vertical direction.

[0051] During specific operation, the stirring range of the assembled blades 26 is increased by the broken line stirring bar 25, the activity of each proportion of materials is improved, and then the overall rotation stirring effect is improved, thereby further improving the mixing and preparation efficiency of the solvent-based paint.

[0052] See also Figure 2 , Figure 5 , Figure 7 , Figure 8 and Fig. 9The mounting plate 24 is provided with a reinforcing component 261 for supporting the assembling leaves 26 after the assembling leaves 26 are assembled. The reinforcing component 261 includes a swivel 2611 rotatably connected to the outer side of the mounting plate 24. Connecting columns 2612 corresponding to the assembling leaves 26 are fixedly connected at equal intervals on the lower side of the swivel 2611. The lower end of the connecting column 2612 is fixedly connected to an arc bar 2613. The lower side of the arc bar 2613 is symmetrically fixedly connected to a leaf-stopping column 2614. The vertical central axis surface of the arc bar 2613 coincides with the vertical central axis surface of the assembling leaf 26. The top of the assembling leaf 26 is provided with an embedding hole corresponding to the connecting column 2612.

[0053] During specific operation, after the assembling leaves 26 are assembled, each connecting column 2612 cooperates with the corresponding embedding hole. When the assembling leaves 26 assembled into a complete circular plate structure move down to extrude the paint, the connecting column 2612 will press the outer arc edge of the assembling leaves 26, increase the force points of the assembling leaves 26, and effectively improve the side strength of the assembling leaves 26, thereby improving the stability and effect of the complete circular plate structure moving down to extrude the paint, as well as the overall service life of the device.

[0054] See also Figure 2 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 Each assembling leaf 26 is provided with a reinforcing component 262 for supporting the assembling leaf 26 when the assembling leaf 26 is unfolded. The reinforcing component 262 includes two limiting slide grooves 2624 arranged at the top of the assembling leaf 26 along the radial direction of the assembling leaf 26. The two limiting slide grooves 2624 are symmetrical about the vertical central axis of the assembling leaf 26. A mounting block 2622 is connected to the limiting slide groove 2624 for sliding and limiting. The mounting block 2622 is provided with a limiting groove on one side close to the center of the assembling leaf 26. A cylinder plate 2621 is hinged in the limiting groove through a pin shaft, and a torsion spring 2625 sleeved on the outside of the pin shaft is connected to the cylinder plate 2621 and the inner wall of the limiting groove. A spring 2623 is connected between the inner wall of the limiting slide groove 2624 on the side away from the central axis of the stirring main shaft 21 and the side end of the mounting block 2622, and an avoidance groove is provided on the top of the side of the assembling leaves 26 corresponding to the inner cylinder 214 and the middle cylinder 213 close to the central axis of the stirring main shaft 21; due to the limitation at the top of the limiting groove, the cylinder plate 2621 can only rotate downward.

[0055] When the assembling leaves 26 are unfolded for stirring, the assembling leaves 26 have a tendency to move up and down, and will be affected by the flow force of the paint. The cylinder plate 2621 is in an inclined state under the combined action of the torsion spring 2625 and the spring 2623, and the corresponding ends of the cylinder plate 2621 are respectively pressed against the sides of the outer cylinder 212, the inner cylinder 214 and the middle cylinder 213. The sides of the outer cylinder 212, the inner cylinder 214 and the middle cylinder 213 form a triangular structure with the corresponding assembling leaves 26 and the cylinder plate 2621, thereby effectively improving the structural strength of the assembling leaves 26, thereby helping to improve the stirring effect and the overall service life of the device.

[0056] When the assembling leaves 26 are assembled, the inner cylinder 214 is retracted first, and the assembling leaves 26 and the cylinder plates 2621 corresponding to the inner cylinder 214 move up synchronously. When the upward inclined end of the cylinder plates 2621 corresponding to the inner cylinder 214 is pressed down to abut against the bottom of the middle cylinder 213, the inner cylinder 214 is pressed down to continue to move upward, which will cause the corresponding cylinder plates 2621 to rotate downward. At the same time, the mounting block 2622 slides along the limiting slide groove 2624 and compresses the spring 2623. Finally, the inclination angle of the cylinder plates 2621 corresponding to the inner cylinder 214 and the middle cylinder 213 is reduced but not in a horizontal state. An avoidance groove is provided on the top of the side of the assembling leaves 26 corresponding to the inner cylinder 214 and the middle cylinder 213 close to the central axis of the stirring main shaft 21 to ensure that the cylinder plates 2621 can rotate under the downward pressing force to avoid affecting the assembly of the assembling leaves 26. Finally, the inclination angle of the cylinder plate 2621 is reduced but not in a horizontal state, in order to ensure that when the subsequent assembly leaves 26 are unfolded, the cylinder plate 2621 can rotate upward and reset under the dual resilience of the torsion spring 2625 and the spring 2623.

[0057] See also Figures 1 to 9 The present invention also provides a solvent-based paint mixing method, which is implemented in conjunction with the above-mentioned solvent-based paint mixing device, and specifically includes the following steps: Step 1: Place the raw materials of the solvent-based paint into the mixing tank 1, and then expand and extend the stirring main shaft 21 through the length adjustment component 211.

[0058] Step 2: Start the lifting component 23 to control the stirring main shaft 21 to move up and down, and start the driving component 22 to drive the assembling blades 26 to rotate to mix and stir the solvent-based paint.

[0059] Step 3: After the mixing is completed, the driving component 22 is turned off, the stirring main shaft 21 is raised, and then the length adjustment component 211 is reversely operated to control the stirring main shaft 21 to shorten, so that all the assembled leaves 26 are combined and assembled into a complete circular plate structure.

[0060] Step 4: Open the discharge control assembly 28 and lower the stirring main shaft 21 so that the complete circular plate structure presses down the solvent-based paint and discharges the solvent-based paint from the extrusion hole 281 .

[0061] See also Figures 1 to 9 Specific working principle: S1: Put the raw materials of solvent-based paint into the mixing tank 1 through the opening of the mixing tank 1, then control the gear 2113 to rotate through the motor 2112, and the gear 2113 drives the rack bar 2111 to move downward, and the downward movement of the rack bar 2111 drives the inner cylinder 214 to move downward in the middle cylinder 213, and when the guide block 2 on the inner cylinder 214 moves down to the lower end of the guide groove 2131, the guide block 2 drives the middle cylinder 213 to move downward synchronously until the guide block 1 contacts the lower end of the guide groove 1 2121, completing the expansion and extension of the entire stirring main shaft 21.

[0062] S2: Motor 221 controls gear 222 to rotate, gear 222 drives gear ring 1 223 to rotate, gear ring 1 223 drives outer cylinder 212 to rotate, so that stirring main shaft 21 rotates as a whole, performs rotation stirring and mixing, and in the mixing stage, at the same time, motor 3 231 controls screw rod 232 to rotate, screw rod 232 drives movable support plate 234 to rise and fall, movable support plate 234 and vertical plate 2341 drive mounting plate 24 to rise and fall as a whole, mounting plate 24 drives stirring main shaft 21 to rise and fall as a whole, and at this time stirring main shaft 21 is unfolded, and assembled leaves 26 on inner cylinder 214, middle cylinder 213 and outer cylinder 212 are dispersed, so that in the mixing stage, a plurality of assembled leaves 26 which are dispersed up and down and staggered in the circumferential direction are used to synchronously implement circumferential stirring and mixing and upper and lower multi-depth stirring and mixing.

[0063] S3: After the stirring and mixing is completed, the stirring main shaft 21 is raised as a whole so that the uppermost assembling leaves 26 are above the upper surface of the solvent-based paint, and then the motor 2112 is reversed, and the gear 2113 drives the rack bar 2111 to move upward, and the upward movement of the rack bar 2111 drives the inner cylinder 214 to move upward in the middle cylinder 213. After the assembling leaves 26 on the inner cylinder 214 and the middle cylinder 213 are in the same plane, the inner cylinder 214 and the middle cylinder 213 will move up synchronously until all the assembling leaves 26 are in the same plane, so that all the assembling leaves 26 are combined and assembled into a whole circle.

[0064] S4: After the assembly is completed, the electric push rod 2842 controls the movement of the rack 2841, and the rack 2841 drives the gear ring 2843 to control the rotation of the rotating sleeve 283. During the rotation stage of the rotating sleeve 283, the extrusion hole 281 thereon will coincide with the extrusion hole 281 on the fixed sleeve 282. Under the extrusion of the complete circular plate structure assembled by the assembling leaves 26, the solvent-based paint is discharged from the extrusion holes 281 that are interconnected from top to bottom. While the complete circular plate structure assembled by the assembling leaves 26 moves downward to extrude and discharge, the circular plate structure also scrapes the inner wall of the mixing tank 1.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
