Description

Technical Field

[0002] Mixing paint with surfactants is a key step in paint production and application. The main purpose is to improve the dispersion, fluidity and adhesion of the paint. Surfactants play a role in reducing surface tension, promoting the dispersion of pigments and fillers, and improving wettability and rheology in paints. However, there are still some problems in the actual mixing process of surfactants and paints.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

A bevel gear 14 is fixedly mounted on the outer surface of the stirring shaft 3 located above the top plate 2. The bevel gear 14 and the bevel gear 2 6 are meshed with each other. A buoyancy defoaming component 13 is arranged on the outer surface of the stirring shaft 3 located inside the mixing tank 1. A driving component 9 and an intermittent feeding component 11 are arranged above the mixing tank 1. An auxiliary defoaming component 10 is arranged on the outer surface of the mixing tank 1. A plurality of supporting legs 8 are fixedly mounted on the outer surface of the mixing tank 1. The supporting legs 8 can make the device as a whole more stable during actual use.

[0035] During operation, in the actual use process, the paint to be mixed is first added to the inside of the mixing tank 1, and then the surfactant to be added is added to the inside of the material box 7, and then the drive motor 5 is controlled to start. During the start-up process of the drive motor 5, the bevel gear 2 6 can be driven to rotate, thereby driving the stirring shaft 3 to rotate inside the mixing tank 1 through the bevel gear 1 4, and then the fixed disk 1 15, the fixed disk 2 16 and the stirring blade 17 on the outer surface of the stirring shaft 3 rotate at high speed inside the mixing tank 1, so as to achieve mixing and stirring of the paint inside the mixing tank 1, and in this process, the surfactant inside the material box 7 can be intermittently added to the inside of the mixing tank 1 through the driving component 9 and the intermittent feeding component 11, and fully mixed with the paint.

[0036] The buoyancy debubbling assembly 13 includes a sleeve frame 1301, and a plurality of limit slots 1309 are provided inside the sleeve frame 1301 and the fixed plate 15. A plurality of limit strips 14 are fixedly installed on the outer surface of the stirring shaft 3. The number of the limit slots 1309 corresponds to the number of the limit strips 14. The sleeve frame 1301 is movably connected to the outer surface of the stirring shaft 3 through the limit strips 14. The buoyancy debubbling assembly 13 is used to cut bubbles.

[0037] An outer ring frame 1303 is arranged on the outer side of the sleeve frame 1301, and a plurality of external connecting rods 1302 are fixedly connected between the sleeve frame 1301 and the outer ring frame 1303, a plurality of buoyancy plates 1305 are arranged on the outer side of the outer ring frame 1303, a plurality of external connecting rods 2 1304 are fixedly connected between the plurality of buoyancy plates 1305 and the outer ring frame 1303, a plurality of bubble removing blades 1306 are fixedly installed on the outer surface of the buoyancy plate 1305, a spiral blade 18 is fixedly connected between the fixed disk 1 15 and the fixed disk 2 16, and the spiral blade 18 is an elastic structure, buoyancy balls 1307 are fixedly installed on the bottom surfaces of the plurality of external connecting rods 2 1304, and a connecting rod 3 1308 is fixedly connected between the bottom surface of the sleeve frame 1301 and the top surface of the fixed disk 15.

[0038] During operation, after the paint is added to the interior of the mixing tank 1, as the paint level inside the mixing tank 1 rises, the buoyancy of the buoyancy plate 1305 and the buoyancy ball 1307 moves upward on the outer surface of the stirring shaft 3 until the buoyancy plate 1305 floats on the paint level surface, and when the stirring shaft 3 rotates, the buoyancy plate 1305 can be driven to rotate synchronously on the paint level surface under the limiting action of the limiting bar 14, and then drive the multiple bubble removal blades 1306 on the outer surface of the buoyancy plate 1305 to rotate, thereby achieving the cutting of bubbles generated during the paint mixing process, so that the bubbles floating on the paint level surface burst, and reduce bubbles in the mixing and stirring process.

[0039] Through the above, the buoyancy debubbling component 13 can always float on the liquid level of the coating according to the height of the liquid level inside the mixing tank 1, and the bubbles generated by mixing and stirring will be located on the surface of the liquid, so that the bubbles generated will be broken by the rotation of the debubbling blade 1306, so that the bubbles on the liquid surface can be effectively reduced during the stirring process, thereby improving the mixing effect between the coating and the surfactant.

[0040] Among them, a connecting rod 3 1308 is fixedly connected between the sleeve frame 1301 and the fixed disk 15. Therefore, when the sleeve frame 1301 rises with the liquid level, it can synchronously drive the fixed disk 15 to rise synchronously on the outer surface of the stirring shaft 3. Because the spiral blade 18 is an elastic structure, the spiral blade 18 can be stretched, that is, when the fixed disk 15, the fixed disk 2 16 and the stirring blade 17 stir the paint inside the mixing tank 1, the spiral blade 18 can stir the material below the mixing tank 1 upward, thereby further improving the mixing effect between the paint and the surfactant, and in this process, the length of the spiral blade 18 can be adjusted according to the height of the fixed disk 15, that is, the length of the spiral blade 18 can be adjusted according to the amount of paint inside the mixing tank 1, so that the paint can be mixed more completely.

[0041] The auxiliary defoaming component 10 includes a movable clamping rod 1001 and a fixed box 1002, wherein the movable clamping rod 1001 is movably inserted into the interior of the top plate 2, and the bottom end of the movable clamping rod 1001 is attached to the top surface of the buoyancy plate 1305, and the fixed box 1002 is fixedly installed on the outer surface of the mixing tank 1, and a shaping cylinder 1003 is fixedly installed inside the fixed box 1002, and a liquid storage capsule 1004 is arranged inside the fixed box 1002, and a sleeve plate 1005 is sleeved on the outer surface of the shaping cylinder 1003, and the sleeve plate 1005 is movably clamped in the interior of the liquid storage capsule 1004, and a clamping groove 1006 is provided on the outer surface of the shaping cylinder 1003, and a clamping frame 1007 is movably clamped inside the clamping groove 1006, and the clamping frame 1007 is located in the sleeve Below the connecting plate 1005, a connecting rod 1008 is fixedly installed on the top surface of the clamping frame 1007, a connecting plate 1009 is fixedly installed on the top of the connecting rod 1008, the top of the movable clamping rod 1001 is fixedly connected to the bottom surface of the connecting plate 1009, a discharge pipe 1010 is fixedly connected to the surface of one side of the fixed box 1002, a solenoid valve 1012 is fixedly installed on the outer surface of the discharge pipe 1010, a liquid injection pipe 1013 is fixedly connected to the surface of one side of the fixed box 1002, a solenoid valve 1014 is fixedly installed on the outer surface of the liquid injection pipe 1013, one end of the solenoid valve 1014 is fixedly connected to a polymerization tube 1015, and the bottom surface of the polymerization tube 1015 located above the material box 7 is fixedly connected to a discharge pipe 1016.

[0042] During operation, when the buoyancy plate 1305 rises with the increase of the liquid level inside the mixing tank 1, it will synchronously drive the movable clamping rod 1001 to move upward. When the movable clamping rod 1001 moves upward, it can drive the sleeve plate 1005 to move upward inside the fixed box 1002 under the action of the connecting plate 1009 and the discharge pipe 1010. During the movement, the liquid storage capsule 1004 can be squeezed, and the defoaming agent inside the liquid storage capsule 1004 can be squeezed into the inside of the discharge pipe 1010, and finally sent to the inside of the material box 7. In this process, the defoaming agent is added. The amount can be controlled by the amount of paint inside the mixing tank 1, that is, the more paint is added to the mixing tank 1, the higher the buoyancy plate 1305 floats, and the higher the height of the movable clamping rod 1001 is driven to move, so that the amount of defoaming agent finally added to the material box 7 is also greater, thereby achieving the purpose of automatically adding a corresponding amount of defoaming agent according to the liquid level height inside the mixing tank 1. Finally, the defoaming agent can be added to the interior of the mixing tank 1 through the intermittent feeding component 11 inside the material box 7, so as to further reduce the bubbles generated when the paint inside the mixing tank 1 is stirred.

[0043] The driving assembly 9 includes a mounting plate 901, which is fixedly mounted on one side of the mixing tank 1. A rotating shaft 902 is rotatably mounted inside the mounting plate 901, and a bevel gear 3 903 is fixedly mounted on the outer surface of the rotating shaft 902. The bevel gear 3 903 and the bevel gear 1 4 are meshed with each other. The driving assembly 9 is used to drive the intermittent feeding assembly 11 and the mixing assembly 12.

[0044] A half gear 904 is fixedly sleeved on the outer surface of the rotating shaft 902, a rectangular frame 905 is arranged on the outer side of the half gear 904, tooth grooves 909 are opened on the inner walls of both sides of the rectangular frame 905, a positioning plate 906 is fixedly installed on the surface of one side of the top plate 2, a plug-in rod 907 is inserted into the interior of the positioning plate 906, one end of the plug-in rod 907 is fixedly connected to the surface of one side of the rectangular frame 905, and a return spring 908 is arranged on the outer surface of the plug-in rod 907.

[0045] During operation, when the driving motor 5 drives the bevel gear 4 to rotate, it can also drive the bevel gear 3 903 to rotate. When the bevel gear 3 903 rotates, it drives the half gear 904 to rotate. As the half gear 904 engages and moves away from the tooth groove 909 opened on the inner wall of the rectangular frame 905, it can drive the rectangular frame 905 to move back and forth between the two positioning plates 906, and then drive the intermittent feeding component 11 and the mixing component 12, so that the intermittent feeding component 11 and the mixing component 12 can be driven to operate during the mixing process.

[0046] The intermittent feeding assembly 11 includes a C-shaped frame 1101, which is fixedly mounted on the top surface of the mounting plate 901. A material tank 1102 is fixedly mounted inside the C-shaped frame 1101. A cavity 2 1112 and a cavity 1 1111 are provided inside the material tank 1102. The interior of the cavity 1 1111 and the cavity 2 1112 are both sealed and connected with a sealing plug 1113. A fixing rod 1103 is fixedly connected between the two sealing plugs 1113. A connecting rod 1 910 is fixedly connected between one side surface of the fixing rod 1103 and the rectangular frame 905. A suction pipe is fixedly connected to the outer sides of the cavity 1 1111 and the cavity 2 1112. 1114, one end of the suction pipe 1114 extends to the interior of the material box 7, a one-way valve 1115 is fixedly installed on the outer surface of the suction pipe 1114, a discharge pipe 1104 is fixedly connected to the top surface of the material tank 1102, a one-way valve 1105 is fixedly connected to the outer surface of the discharge pipe 1104, a rectangular tube 1106 is fixedly connected to the top of the discharge pipe 1104, a storage cavity 1117 is opened inside the stirring shaft 3, a through hole 1118 is installed inside the storage cavity 1117, a conveying pipe 1107 is fixedly connected between the through hole 1118 and the rectangular tube 1106, and a plurality of through holes 1118 are opened inside the storage cavity 1117.

[0047] During operation, when the rectangular frame 905 moves back and forth, it can synchronously drive the connecting rod 1 910 to move, thereby causing the fixing rod 1103 to move back and forth between the cavity 1 1111 and the cavity 2 1112, thereby driving the sealing card plugs 1113 at both ends of the fixing rod 1103 to move back and forth inside the cavity 2 1112 and the cavity 1 1111 respectively. During the back and forth movement of the sealing card plug 1113, the surfactant inside the material box 7 and the defoaming agent that subsequently enters the material box 7 can be sucked into the cavity 1111 through the suction pipe 1114. 11 and the interior of cavity 1112, and finally squeezed by the sealing plug 1113 into the interior of the discharge pipe 1104, and then into the interior of the rectangular tube 1106, and finally entered into the storage cavity 1117 through the conveying pipe 1107 and the rotary joint 1108, and then discharged to the interior of the mixing tank 1 through the through hole 1118, thereby achieving the purpose of intermittently adding the surfactant in the material box 7 and the defoaming agent that enters subsequently into the mixing tank 1, so that the surfactant and the defoaming agent can be better mixed with the paint in the mixing tank 1.

[0048] Moreover, after the surfactant and the defoaming agent enter the storage chamber 1117, the centrifugal force generated by the rotation of the stirring shaft 3 can cause the surfactant and the defoaming agent that have entered the storage chamber 1117 to be scattered in a relatively dispersed state inside the mixing tank 1 through the through hole 1118, thereby further improving the mixing effect between the coating and the surfactant.

[0049] Among them, the interior of cavity one 1111 and the interior of cavity two 1112 are fixedly installed with spiral blades two 1116. Through the set spiral blades two 1116, when the surfactant and defoaming agent in the material box 7 enter the interior of cavity one 1111 and cavity two 1112, they will pass through spiral blades two 1116, so that the surfactant and defoaming agent entering the interior of cavity one 1111 and cavity two 1112 will generate vortex, thereby enabling the surfactant and the defoaming agent to be better mixed. That is, after the two are added to the interior of the mixing tank 1, the mixing effect with the mixing tank 1 is greatly improved, and the sealing card plug 1113 moves back and forth, that is, it can enable the surfactant and the defoaming agent entering the interior of cavity one 1111 and cavity two 1112 to generate vortexes in different directions, thereby further improving the mixing effect between the two.

[0050] The mixing assembly 12 includes a mixing shaft 1201, which is rotatably installed inside the material box 7. A driven wheel 1202 is fixedly installed on the top of the mixing shaft 1201. A plurality of mixing plates 1203 are fixedly installed on the outer surface of the mixing shaft 1201 located inside the material box 7. An extension rod 1109 is fixedly connected to the surface of one side of the fixed rod 1103. A tooth plate 1110 is fixedly installed on one end of the extension rod 1109. The tooth plate 1110 and the driven wheel 1202 are meshed with each other.

[0051] During operation, when the fixed rod 1103 moves back and forth, it can drive the extension rod 1109 and the tooth plate 1110 to move synchronously. Since the tooth plate 1110 and the driven wheel 1202 are meshed with each other, when the tooth plate 1110 moves back and forth, it can drive the mixing shaft 1201 to rotate back and forth inside the material box 7 under the action of the driven wheel 1202, and then drive the mixing plate 1203 to move inside the material box 7, so as to preliminarily mix the surfactant and defoaming agent inside the material box 7, so that the subsequent addition to the mixing tank 1 can be better mixed with the paint inside the mixing tank 1.

[0052] Specifically, the working process or working principle of the surfactant mixing device for coating production is as follows: when in use, the coating to be mixed is first added to the inside of the mixing tank 1, and then the surfactant to be added is added to the inside of the material box 7, and then the driving motor 5 is controlled to start. During the starting process of the driving motor 5, the bevel gear 2 6 can be driven to rotate, thereby driving the stirring shaft 3 to rotate inside the mixing tank 1 through the bevel gear 1 4, and then the fixed disk 1 15, the fixed disk 2 16 and the stirring blade 17 on the outer surface of the stirring shaft 3 rotate at high speed inside the mixing tank 1, so as to achieve mixing and stirring of the coating inside the mixing tank 1.

[0053] After the paint is added to the mixing tank 1, as the paint level inside the mixing tank 1 rises, the paint moves upward on the outer surface of the stirring shaft 3 under the buoyancy of the buoyancy plate 1305 and the buoyancy ball 1307 until the buoyancy plate 1305 floats on the paint level surface. When the stirring shaft 3 rotates, the buoyancy plate 1305 can be driven to rotate synchronously on the paint level surface under the limiting action of the limiting bar 14, thereby driving the multiple bubble removal blades 1306 on the outer surface of the buoyancy plate 1305 to rotate, thereby cutting the bubbles generated during the paint mixing process.

[0054] When the buoyancy plate 1305 rises with the increase of the liquid level inside the mixing tank 1, it will synchronously drive the movable clamping rod 1001 to move upward. When the movable clamping rod 1001 moves upward, it can drive the sleeve plate 1005 to move upward inside the fixed box 1002 under the action of the connecting plate 1009 and the discharge pipe 1010, and squeeze the defoaming agent inside the liquid storage capsule 1004 into the inside of the discharge pipe 1010, and finally send it to the inside of the material box 7. Finally, the defoaming agent can be added to the inside of the mixing tank 1 through the intermittent feeding component 11 inside the material box 7, so as to further reduce the bubbles generated when the paint inside the mixing tank 1 is stirred.

[0055] When the driving motor 5 drives the bevel gear 1 4 to rotate, it can also drive the bevel gear 3 903 to rotate. When the bevel gear 3 903 rotates, it drives the half gear 904 to rotate. As the half gear 904 engages and moves away from the tooth groove 909 provided on the inner wall of the rectangular frame 905, it can drive the rectangular frame 905 to move back and forth between the two positioning plates 906, thereby driving the intermittent feeding component 11 and the mixing component 12, so that the intermittent feeding component 11 and the mixing component 12 can be driven to operate during the mixing process. When the rectangular frame 905 moves back and forth, it can synchronously drive the connecting rod 1 910 to move, thereby making the fixing rod 1103 move between the cavity 1 1111 and the cavity 2 1112. The sealing card plugs 1113 at both ends of the fixed rod 1103 move back and forth in the cavity 1112 and the cavity 1111 respectively. In the process of the back and forth movement of the sealing card plugs 1113, the surfactant in the material box 7 and the defoaming agent that subsequently enters the material box 7 can be sucked into the cavity 1 1111 and the cavity 2 1112 through the suction pipe 1114, and finally squeezed into the discharge pipe 1104 by the sealing card plug 1113, and then into the rectangular tube 1106, and finally entered into the storage cavity 1117 through the conveying pipe 1107 and the rotary joint 1108, and then discharged to the interior of the mixing tank 1 through the through hole 1118.
