Description

Technical Field

[0001] This invention relates to the technical field of coating preparation, and more specifically, to an antibacterial and mildew-resistant interior wall coating and its processing apparatus. Background Technology

[0002] Antibacterial and mildew-resistant interior wall paint is a functional wall material that adds antibacterial and mildew-resistant agents to ordinary paint. It effectively inhibits the growth of bacteria and mold on walls, making it especially suitable for damp environments such as kitchens and bathrooms. Its core components include synthetic resin emulsions (such as vinyl acetate-acrylic emulsions), pigments and fillers, water, and trace amounts of antibacterial and mildew-resistant additives (usually accounting for 1%-3% of the total). This type of paint combines decorative appeal with environmental friendliness, making it an ideal choice for creating a healthy home.

[0003] If antibacterial and mildew-resistant interior wall paint is not thoroughly stirred before application, serious consequences can result from component sedimentation. When the paint is left to stand, the denser antibacterial and mildew-resistant agents and pigments will settle to the bottom, while the resin and water will float to the top. If used directly without stirring, the upper half of the paint will be too thin, resulting in poor hiding power and easy sagging; the lower half will have excessive accumulation of antibacterial agents and pigments, causing uneven wall color (blooming). More importantly, the antibacterial and mildew-resistant factors cannot be evenly dispersed, significantly weakening the core efficacy. In addition, unequally stirred paint will form an uneven film, resulting in a rough film with poor adhesion after drying, making it prone to peeling and reducing scrub resistance. The inconsistent consistency will also result in an unpleasant feel during application. Therefore, it is essential to thoroughly stir the paint with a mechanical mixer before application to ensure homogeneity of components, thus guaranteeing its antibacterial and mildew-resistant effects and decorative finish.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an antibacterial and mildew-proof interior wall coating and processing device, in order to achieve a more practical purpose. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an antibacterial and mildew-resistant interior wall coating and a processing device to solve these issues.

[0006] This invention provides an antibacterial and mildew-resistant interior wall coating and its processing device, achieved through the following specific technical means:

[0007] An antibacterial and mildew-resistant interior wall coating and processing device includes a mixing tank, a rotating shaft installed on the central axis of the mixing tank, a liquid circulation device installed at the middle position of the rotating shaft, a stirring device rotatably installed inside the mixing tank, and a drive assembly installed at the upper end of the mixing tank.

[0008] The liquid storage and circulation device includes a rotating cylinder fixedly connected to a rotating shaft. Multiple outlet pipes are evenly installed on the outer wall of the lower end of the rotating cylinder. A self-opening component is slidably installed through one end of each outlet pipe near the rotating cylinder. A first spring, used in conjunction with the outlet pipe, is sleeved on the outer wall of the self-opening component. Short rods and long rods are evenly distributed inside the rotating cylinder. A reset component is installed at the lower end of each long rod. A sealing plate is slidably installed inside the rotating cylinder. The short rods and long rods pass through the sealing plate. Multiple inlet pipes are evenly installed on the outer wall of the upper end of the rotating cylinder. Inlet holes are opened on the outer wall of each inlet pipe. A filter screen is attached to the outer wall of each inlet pipe at the position of the inlet hole. A liquid level sensor is installed inside the rotating cylinder.

[0009] In practical applications, the coating is stored inside the rotating drum through a liquid circulation device. Since the outlet of the liquid outlet pipe is located on the back, the back of the drum is under negative pressure when it rotates, so the coating will not return from the outlet to the inside of the liquid outlet pipe. Moreover, the outer wall of the front of the liquid inlet pipe of this device has an inlet hole, so during the rotation, coating will enter the inside of the liquid inlet pipe from the inlet hole, and then enter the upper end of the sealing plate from the inside of the liquid inlet pipe, thereby pushing the sealing plate downward. When the sealing plate reaches the bottom, the sealing plate disengages from the short rod, and a round hole will be opened to leak out. The coating at the top of the sealing plate enters the lower position of the sealing plate through the round hole, and finally exits from the outlet. The coating cleans the inside of the rotating drum, thereby avoiding coating waste.

[0010] Furthermore, the self-opening component includes a first square strip slidably connected to the outlet pipe. An arc-shaped plate is fixedly provided at one end of the first square strip. The inner arc diameter of the arc-shaped plate is larger than the outer wall diameter of the outlet pipe. A second connecting rod is fixedly provided at the other end of the arc-shaped plate. The outer diameter of the second connecting rod is smaller than the thickness of the first square strip. A second square strip is fixedly provided at the other end of the second connecting rod. A limit block is fixedly provided at the other end of the second square strip. An inlet is provided at the inlet end of the outlet pipe. The first spring is located between the limit block and the outlet pipe. An installation rod is fixedly provided at one end of the arc-shaped plate. An anti-clogging needle for use with the outlet hole is fixedly provided on the outer wall of the installation rod.

[0011] The height of the inlet is equal to that of the first square bar. The two ends of the outlet pipe are respectively provided with square holes for use with the first and second square bars. The outlet pipe is provided with an outlet hole in the opposite direction of the rotation direction. The opening direction of the inlet hole of the inlet pipe is opposite to that of the outlet hole of the outlet pipe directly below it. The number and diameter of the outlet holes need to be adjusted in practice.

[0012] In practical applications, when the outlet pipe is rotating, the arc plate will pull the self-opening component to move under resistance, so that the second strip enters the position of the inlet, thereby connecting the outlet pipe with the inside of the rotating drum.

[0013] Furthermore, the stirring device includes an outer cylinder sleeved around both ends of the outer wall of the rotating shaft, with a first connecting rod fixedly installed at each end of the outer wall of the outer cylinder, and a connecting ring fixedly installed at the other end of the first connecting rod at the same end, and a turntable for use with the drive assembly fixedly installed at the upper end of the outer cylinder.

[0014] In practical applications, since the stirring device and the rotating drum rotate in opposite directions, the negative pressure on the back of the outlet pipe is increased, while the liquid inflow on the front of the outlet pipe is also increased.

[0015] Furthermore, the reset assembly includes a sealing slider that is slidably connected to the receiving hole. A fixing rod is fixedly installed on the upper end of the sealing slider, and a sealing cylinder is fixedly installed on the upper end of the fixing rod. The upper end of the sealing cylinder is slidably connected to the lower end of the long rod. A partition and a limiting ring are fixedly installed at the middle positions inside and outside the sealing cylinder, respectively. A water outlet is opened at the lower end of the sealing cylinder. A second spring is provided between the sealing slider and the receiving hole.

[0016] A connecting pipe is rotatably installed at the upper end of the rotating drum. A flow guiding cavity is opened inside the rotating drum. A receiving hole for use with the reset assembly is opened at the bottom of the rotating drum. A connecting cavity is provided between the receiving hole and the flow guiding cavity. A through hole is opened at the lower end of the receiving hole.

[0017] In practical applications, when new additives need to be injected into the rotating drum, the coating enters through the connecting pipe, then into the guide chamber, then into the connecting chamber, then into the upper end of the receiving hole, and finally into the sealing cylinder. The sealing cylinder rises under pressure, pushing the sealing plate upwards. The sealing plate then contacts the short rod, and the sealing cylinder continues to rise. The coating is sprayed out from the water outlet and finally enters the lower end of the rotating drum until the coating reaches the set height. The liquid level can be controlled by a liquid level sensor or a metering pump, thus completing the addition of the additive.

[0018] Furthermore, the drive assembly includes a motor mounted on the upper end of the mixing tank, a gear mounted on the outer wall of the output shaft of the motor, a first tooth for cooperating with the gear on the upper end of the turntable, and a second tooth for cooperating with the gear on the outer wall of the upper end of the rotating shaft.

[0019] Furthermore, an antibacterial and mildew-resistant interior wall coating comprises the following materials: 30%-50% vinyl acetate-acrylic emulsion, 30%-60% pigments and fillers, approximately 1%-3% total amount of antibacterial and mildew-resistant agents, 20%-30% deionized water / purified water, and 1% dispersant.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This device is equipped with a liquid circulation system. When the additive inside the rotating drum is used up, the inside of the rotating drum is cleaned with the coating, which effectively avoids the waste of coating residue inside the rotating drum and increases the stirring effect.

[0022] 2. This device is equipped with a self-opening component. Only after the drum rotates will the additive inside the drum flow out from the outlet pipe, thus preventing the additive from being discharged from the outlet pipe when it is being added.

[0023] 3. Since the stirring device and the rotating drum rotate in opposite directions, the negative pressure on the back of the outlet pipe is increased, and the liquid inflow on the front of the outlet pipe is also increased.

[0024] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] Example:

[0040] As attached Figure 1 To be continued Figure 9 As shown:

[0041] The present invention provides an antibacterial and mildew-proof interior wall coating and a processing device, including a mixing tank 1, a rotating shaft 5 installed on the central axis of the mixing tank 1, a liquid circulation device 3 installed at the middle position of the rotating shaft 5, a stirring device 2 rotatably installed inside the mixing tank 1, and a drive assembly installed at the upper end of the mixing tank 1.

[0042] The liquid storage and circulation device 3 includes a rotating drum 301 fixedly connected to a rotating shaft 5. Multiple liquid outlet pipes 306 are evenly installed on the outer wall of the lower end of the rotating drum 301. A self-opening component 308 is slidably installed through one end of the liquid outlet pipe 306 near the rotating drum 301. A first spring 307 for use with the liquid outlet pipe 306 is sleeved on the outer wall of the self-opening component 308. Short rods 304 and long rods 305 are evenly distributed inside the rotating drum 301. A reset component 309 is installed at the lower end of the long rod 305. A sealing plate 302 is slidably installed inside the rotating drum 301. Short rods 304 and long rods 305 pass through the sealing plate 302 respectively. Multiple liquid inlet pipes 303 are evenly installed on the outer wall of the upper end of the rotating drum 301. A liquid inlet hole 3031 is opened on the outer wall of the liquid inlet pipe 303. A filter screen is attached to the outer wall of the liquid inlet pipe 303 at the position of the liquid inlet hole 3031. A liquid level sensor is installed inside the rotating drum 301.

[0043] In practical applications, the coating is stored inside the rotating drum 301 by the liquid circulation device 3. Since the liquid outlet 3062 of the liquid outlet pipe 306 is located on the back, the back of the rotating drum 301 is under negative pressure when it rotates. Therefore, the coating will not return from the liquid outlet 3062 to the inside of the liquid outlet pipe 306. Moreover, the outer wall of the front of the liquid inlet pipe 303 of this device has a liquid inlet 3031, so during rotation, coating will enter the inlet pipe 3031 from the liquid inlet 3031. The liquid enters the upper part of the sealing plate 302 from inside the liquid inlet pipe 303, thereby pushing the sealing plate 302 downward. When the sealing plate 302 reaches the bottom, the sealing plate 302 disengages from the short rod 304, resulting in leakage through the round hole. The coating material at the upper end of the sealing plate 302 enters the lower part of the sealing plate 302 through the round hole and is finally discharged from the liquid outlet 3062. The coating material cleans the inside of the rotating drum 301, thereby avoiding waste of coating material and increasing the stirring effect.

[0044] The self-opening component 308 includes a first square strip 3082 slidably connected to the outlet pipe 306. An arc plate 3081 is fixedly provided at one end of the first square strip 3082. The inner arc diameter of the arc plate 3081 is larger than the outer wall diameter of the outlet pipe 306. A second connecting rod 3083 is fixedly provided at the other end of the arc plate 3081. The outer diameter of the second connecting rod 3083 is smaller than the thickness of the first square strip 3082. A second square strip 3084 is fixedly provided at the other end of the second connecting rod 3083. A limit block 3085 is fixedly provided at the other end of the second square strip 3084. An inlet 3061 is provided at the inlet end of the outlet pipe 306. A first spring 307 is located between the limit block 3085 and the outlet pipe 306. An installation rod is fixedly provided at one end of the arc plate 3081. An anti-blocking needle for use with the outlet hole 3062 is fixedly provided on the outer wall of the installation rod.

[0045] The height of the inlet 3061 is equal to that of the first square bar 3082. The two ends of the outlet pipe 306 are respectively provided with square holes 3063 for use with the first square bar 3082 and the second square bar 3084. The outlet pipe 306 is provided with an outlet hole 3062 in the opposite direction of the rotation direction. The inlet pipe 303 has an inlet hole 3031, and the opening direction of the outlet hole 3062 of the outlet pipe 306 directly below it is opposite. The number and diameter of the outlet holes 3062 need to be adjusted in practice.

[0046] In practical applications, when the outlet pipe 306 is rotating, the arc plate 3081 will pull the self-opening component 308 to move as a whole under resistance, so that the second square bar 3084 enters the position of the inlet 3061, thereby connecting the outlet pipe 306 with the inside of the rotating drum 301.

[0047] The stirring device 2 includes an outer cylinder 202 that is sleeved on both ends of the outer wall of the rotating shaft 5. A first connecting rod 203 is fixedly installed at both ends of the outer wall of the outer cylinder 202. A connecting ring 204 is fixedly installed at the other end of the first connecting rod 203 at the same end. A turntable 201 for use with the drive assembly is fixedly installed at the upper end of the outer cylinder 202 located at the upper end of the outer cylinder 202.

[0048] In practical applications, since the stirring device 2 and the rotating drum 301 rotate in opposite directions, the negative pressure on the back of the liquid outlet pipe 306 is increased, and the liquid inlet volume on the front of the liquid outlet pipe 306 is also increased.

[0049] The reset assembly 309 includes a sealing slider 3091 that is slidably connected to the receiving hole 3012. A fixing rod 3092 is fixedly installed on the upper end of the sealing slider 3091. A sealing cylinder 3093 is fixedly installed on the upper end of the fixing rod 3092. The upper end of the sealing cylinder 3093 is slidably connected to the lower end of the long rod 305. A partition and a limiting ring are fixedly installed at the middle positions inside and outside the sealing cylinder 3093, respectively. A water outlet is opened at the lower end of the sealing cylinder 3093. A second spring is provided between the sealing slider 3091 and the receiving hole 3012.

[0050] A connecting pipe 10 is rotatably installed on the upper end of the rotating drum 301. A flow guiding cavity is opened inside the rotating drum 301. A receiving hole 3012 for use with the reset assembly 309 is opened at the bottom of the rotating drum 301. A connecting cavity 3011 is provided between the receiving hole 3012 and the flow guiding cavity. A through hole 3013 is opened at the lower end of the receiving hole 3012.

[0051] In practical applications, when new additives need to be injected into the rotating drum 301, the coating enters through the connecting pipe 10, then enters the guide cavity, then enters the connecting cavity 3011, and then enters the upper end of the receiving hole 3012. From the upper end of the receiving hole 3012, it enters the sealing cylinder 3093, which rises under pressure, thus pushing the sealing plate 302 upwards. The sealing plate 302 then contacts the short rod 304, and the sealing cylinder 3093 continues to rise. The coating is sprayed out from the water outlet and finally enters the lower end of the rotating drum 301 until the coating reaches the set height. Liquid level control can be achieved through a liquid level sensor or a metering pump, thus completing the addition of the additive.

[0052] The drive assembly includes a motor mounted on the upper end of the mixing tank 1, a gear 4 mounted on the outer wall of the motor's output shaft, a first tooth for cooperating with the gear 4 on the upper end of the turntable 201, and a second tooth for cooperating with the gear 4 on the upper outer wall of the rotating shaft 5.

[0053] One type of antibacterial and mildew-proof interior wall coating includes the following materials: 30%-50% vinyl acetate-acrylic emulsion, 30%-60% pigments and fillers, approximately 1%-3% total amount of antibacterial and mildew-proof agents, 20%-30% deionized water / purified water, and 1% dispersant.

[0054] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
