Abstract

This utility model relates to the technical field of tank mixing devices and discloses a mixing device for an anti-settling coating tank. The device includes a housing with an inlet at the top and an outlet at the bottom. A motor is fixed to the top of the housing, and the bottom of the motor's output shaft passes through the housing and is rotatably connected to it. A rotating shaft is rotatably connected to the top of the inner wall of the housing, and the top of the rotating shaft is fixed to the bottom of the motor's output shaft. This anti-settling coating tank mixing device, through its mixing components, allows the motor to be started, causing the rotating plate to rotate. The inner wall of the arc-shaped groove continuously contacts the outer surface of the round rod, driving the round rod, fixed block, fixed rod, and movable plate towards the inner wall of the housing and compressing the spring. When the round rod leaves the highest point of the arc-shaped groove, the spring releases its elastic force, pulling the movable plate closer to the mixing rod, thus bringing the coating back to the central area, avoiding insufficient mixing, and improving mixing efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of tank stirring devices, specifically a stirring device for anti-settling coating tanks. Background Technology

[0002] Coatings are functional materials that are applied to the surface of objects to form a solid film, and are widely used in construction, industry, home furnishings, and automobiles. Coatings are typically composed of film-forming substances (such as resins and emulsions), pigments, solvents, and additives. During the production process, a stirring device is required to fully mix the components to ensure the uniformity and performance stability of the coating.

[0003] Currently, common paint mixing devices primarily use a rotating stirring shaft to drive stirring blades for mechanical mixing of paint. However, in actual use, the centrifugal force generated by the high-speed rotation of the stirring device can easily throw the paint against the inner wall of the tank, causing the paint to accumulate at the edge of the tank while the central area remains insufficiently mixed. This phenomenon not only reduces mixing efficiency and prolongs mixing time, but may also affect the final quality of the paint due to uneven local composition. Summary of the Invention

[0004] The purpose of this invention is to provide a stirring device for an anti-settling coating storage tank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stirring device for an anti-settling coating storage tank, comprising a box body, an inlet at the top of the box body, an outlet at the bottom of the box body, a motor fixed at the top of the box body, the bottom of the output shaft of the motor penetrating through the box body and rotatably connected to the box body, a rotating shaft rotatably connected to the top of the inner wall of the box body, the top of the rotating shaft fixed to the bottom of the output shaft of the motor, a stirring rod fixed to the outer surface of the rotating shaft, and a mixing component and a lifting component arranged inside the box body;

[0006] The hybrid component includes:

[0007] A round rod is used to drive the synchronous movement of various components.

[0008] Rotating plate, used to drive the movement of various components;

[0009] Movable plate, used to bring back the paint from the edges of the box.

[0010] Preferably, the round rod is slidably connected to the top of the inner wall of the box, a fixing block is fixed to the bottom of the round rod, a rotating plate is fixed through the rotating shaft, the outer surface of the rotating plate has an arc-shaped groove, the inner wall of the arc-shaped groove abuts against the outer surface of the round rod, a fixing rod is fixed to the outer surface of the fixing block, a movable plate is fixed to the end of the fixing rod away from the fixing block, a connecting plate is fixed to the outer surface of the fixing block, a fixing plate is fixed to the top of the inner wall of the box, a spring is fixed to the outer surface of the fixing plate, the end of the spring away from the fixing plate is fixed to the outer surface of the connecting plate, and the movable plate is slidably connected to the top of the inner wall of the box. When the rotating plate rotates, the inner wall of the arc-shaped groove continuously abuts against the outer surface of the round rod, causing the round rod, fixing block, fixing rod, and movable plate to move towards the inner wall of the box and compress the spring. When the round rod leaves the highest point of the arc-shaped groove, the spring releases its elastic force, the movable plate returns to its original position, and the paint accumulated at the edge of the tank due to centrifugal force is brought back to the central area.

[0011] Preferably, the lifting assembly includes a fixed cylinder rotatably connected to the outer surface of the rotating shaft. A connecting ring is slidably connected to the outer surface of the fixed cylinder, and a movable rod is hinged to the outer surface of the connecting ring. The end of the movable rod away from the connecting ring is hinged to the inner side of the movable plate. A circular plate is fixed to the outer surface of the connecting ring, and a through hole is provided on the outer surface of the circular plate. When the movable plate moves away from the rotating shaft, the movable rod flips and pulls the connecting ring upward, causing the circular plate to rise synchronously, thereby lifting the paint that has sunk to the bottom. The through hole allows the circular plate to move upward normally without affecting the normal movement of the circular plate.

[0012] Preferably, both the circular plate and the movable plate have perforations on their outer surfaces to prevent interference with the normal flow of the coating.

[0013] Preferably, the arc-shaped groove is inclined so that when the rotating plate rotates, the movable plate can reciprocate through the spring.

[0014] Preferably, a solenoid valve is installed on the surface of the discharge port to facilitate material discharge.

[0015] Compared with the prior art, the present invention provides a stirring device for an anti-settling coating storage tank, which has the following beneficial effects:

[0016] 1. The mixing device for the anti-settling coating storage tank, through the set mixing components, can rotate the rotating plate by starting the motor. The inner wall of the arc-shaped groove continuously contacts the outer surface of the round rod, driving the round rod, fixed block, fixed rod and movable plate to move towards the inner wall of the tank and compress the spring. When the round rod leaves the highest point of the arc-shaped groove, the spring releases its elastic force and pulls the movable plate closer to the mixing rod, so that the coating is brought back to the central area, avoiding insufficient mixing and improving mixing efficiency.

[0017] 2. The stirring device for the anti-settling coating storage tank, through the lifting component, allows the moving rod to flip and pull the connecting ring upward when the movable plate moves away from the rotating shaft, so that the circular plate rises synchronously, lifting the coating that has settled to the bottom, and then stirring and mixing it again through the stirring rod to prevent sedimentation from affecting the uniformity of mixing.

Detailed Implementation

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a stirring device for an anti-settling coating storage tank, including a box body 1, an inlet 2 at the top of the box body 1, an outlet 3 at the bottom of the box body 1, a motor 4 fixed at the top of the box body 1, the bottom of the output shaft of the motor 4 passing through the box body 1 and rotatably connected to the box body 1, a rotating shaft 5 rotatably connected to the top of the inner wall of the box body 1, the top of the rotating shaft 5 fixed to the bottom of the output shaft of the motor 4, a stirring rod 6 fixed on the outer surface of the rotating shaft 5, and a mixing component 7 and a lifting component 8 arranged inside the box body 1; the mixing component 7 includes: a round rod 70, a fixing block 71, a fixing rod 72, a movable plate 73, a rotating plate 74, an arc groove 75, a fixing plate 76, a connecting plate 77, and a spring 78.

[0024] A round rod 70 is slidably connected to the top of the inner wall of the housing 1. A fixing block 71 is fixed to the bottom of the round rod 70. A rotating plate 74 is fixed through the rotating shaft 5. The outer surface of the rotating plate 74 has an arc-shaped groove 75. The inner wall of the arc-shaped groove 75 abuts against the outer surface of the round rod 70. A fixing rod 72 is fixed to the outer surface of the fixing block 71. A movable plate 73 is fixed to the end of the fixing rod 72 away from the fixing block 71. A connecting plate 77 is fixed to the outer surface of the fixing block 71. A fixing plate 76 is fixed to the top of the inner wall of the housing 1. A spring 7 is fixed to the outer surface of the fixing plate 76. 8. The end of spring 78 away from fixed plate 76 is fixed to the outer surface of connecting plate 77. Movable plate 73 is slidably connected to the top of the inner wall of box 1. Arc groove 75 is set in an inclined shape. When rotating plate 74 rotates synchronously, the inner wall of arc groove 75 continuously abuts against the outer surface of round rod 70, driving round rod 70, fixed block 71, fixed rod 72 and movable plate 73 to move towards the inner wall of box 1 and compress spring 78. When round rod 70 leaves the highest point of arc groove 75, spring 78 releases its elastic force, pulling the entire mechanism to reset, causing movable plate 73 to move closer to stirring rod 6. This reciprocating motion can bring the paint accumulated at the edge of the tank due to centrifugal force back to the central area, avoiding insufficient mixing. At the same time, the periodic reciprocating motion of movable plate 73 significantly improves the stirring efficiency when rotating shaft 5 continues to rotate.

[0025] The lifting assembly 8 includes a fixed cylinder 80, which is rotatably connected to the outer surface of the rotating shaft 5. A connecting ring 84 is slidably connected to the outer surface of the fixed cylinder 80. A movable rod 82 is hinged to the outer surface of the connecting ring 84. The end of the movable rod 82 away from the connecting ring 84 is hinged to the inner side of the movable plate 73. A circular plate 81 is fixed to the outer surface of the connecting ring 84. A through hole 83 is opened on the outer surface of the circular plate 81. Both the outer surfaces of the circular plate 81 and the movable plate 73 have drainage holes. A solenoid valve is installed on the surface of the discharge port 3. When the movable plate 73 moves away from the rotating shaft 5, the movable rod 82 flips and pulls the connecting ring 84 upward, causing the circular plate 81 to rise synchronously, thereby lifting the settled coating material, preventing sedimentation from affecting the mixing uniformity, and further improving the mixing efficiency. After mixing is completed, the discharge port 3 can be controlled by the solenoid valve to discharge the material.

[0026] When the paint needs to be mixed, the paint to be mixed is added through the feed inlet 2. At this time, the motor 4 is turned on, causing the stirring rod 6 to rotate and mix the paint. Simultaneously, as the rotating shaft 5 rotates, the rotating plate 74 rotates synchronously. The inner wall of the arc-shaped groove 75 continuously contacts the outer surface of the round rod 70, thus moving the round rod 70, the fixed block 71, the fixed rod 72, and the movable plate 73 closer to the inner wall of the housing 1. The spring 78 is compressed. When the round rod 70 disengages from the highest point of the arc-shaped groove 75, the spring 78 is released as the rotating plate 74 continues to rotate, thus pulling the fixed block 71, the round rod 70, and the fixed rod 72. When the movable plate 73 is reset, it moves closer to the stirring rod 6, bringing back the coating affected by centrifugal force. This prevents the coating from accumulating at the edge of the tank, which would result in insufficient mixing in the central area. As the rotating shaft 5 continues to rotate, the movable plate 73 reciprocates, improving the mixing efficiency. Simultaneously, when the movable plate 73 moves away from the rotating shaft 5, the movable rod 82 flips, pulling the connecting ring 84 upward, which in turn moves the circular plate 81 upward. This lifts the coating that has settled to the bottom, preventing it from settling and affecting the uniformity of mixing, thus improving mixing efficiency. Once mixing is complete, the coating can be discharged through the solenoid valve and the discharge port 3.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
