Description

Technical Field

[0001] The present invention relates to the technical field of granite preparation, and in particular to a system and process for preparing a weather-resistant liquid granite coating. Background Art

[0002] Liquid granite paint is a kind of imitation stone paint with an appearance and decorative effect that resembles natural granite stone. It is mainly based on synthetic resin emulsion as the base material, natural colored sand, composite rock flakes and a small amount of mica flakes as aggregates, and is added with additives and water. Among them, in the process of mixing the components of granite, fully mixing the aggregates, base materials and additives can further improve the quality of the prepared granite.

[0003] Chinese patent CN114058197B discloses an inorganic liquid granite coating and its preparation method. In terms of mass percentage, the coating comprises 20-30% inorganic nano-silica sol, 1-2% protective colloid, 0.3-1% titanium dioxide, 5-15% inorganic filler, 1-3% other additives, and the balance water.

[0004] However, this technical solution and the prior art have the following defects:

[0005] 1. In the stirring process of preparing liquid granite coating, this solution can only stir locally. Aggregates such as natural sand gathered at the corners cannot be fully mixed with the base material and additives at the stirring point, resulting in uneven stirring and mixing.

[0006] 2. During the stirring process of this solution and the existing technology, due to the strong adhesion of the granite coating, the granite coating in the dead corner of the stirring zone is not directly stirred, which easily causes the granite coating in the dead corner of the stirring zone to solidify into a lump, making it difficult to mix the materials. Summary of the Invention

[0007] The purpose of the present invention is to address the shortcomings of the existing technology and provide a weather-resistant liquid granite paint preparation system. The raw materials after feeding are first sent into the stirring zone for primary stirring, so that the raw materials near the stirring paddle are fully stirred and evenly mixed, ensuring that the raw materials can be stirred with the largest stirring range during the primary stirring. Then, the raw materials that are not stirred evenly in time due to the presence of stirring dead corners in the stirring zone are switched to the mixing zone. The raw materials that are not stirred evenly are squeezed and dispersed in the mixing zone, so that the raw materials that are solidified into clumps away from the stirring paddle can be dispersed after squeezing and dispersing, thereby preventing uneven stirring inside the prepared coating. In addition, after the mixing work, the present invention switches the raw materials in small pieces after mixing to the stirring zone again for secondary mixing, ensuring that the raw materials can be stirred evenly as a whole, avoiding the inhibitory effect of stirring dead corners on mixing.

[0049] As an improvement, the driving unit includes:

[0050] carrier;

[0051] a second driving mechanism, the second driving mechanism being disposed above the carrier;

[0052] The upper portion of the second driving mechanism is connected to a lifting arm;

[0053] One end of the lifting arm is connected to a lifting plate for controlling the lifting of the screening assembly;

[0054] A driving arm for controlling the stirring assembly to perform stirring is provided on the side of the second driving mechanism.

[0055] As an improvement, the feeding unit includes:

[0056] Pre-stored box;

[0057] A push plate, a side portion of which is connected to a third driving mechanism.

[0058] The present invention also provides a process for preparing a weather-resistant liquid granite coating using a system for preparing the weather-resistant liquid granite coating, comprising the following steps:

[0059] Step 1: Feeding process: put the raw materials into the pre-storage frame, and the third driving mechanism intermittently pushes the raw materials in the pre-storage frame into the mixing barrel filled with water through the pushing plate and is located between the screening plate and the upper pressure cover;

[0060] Step 2: Primary stirring process: the guide rod drives the raw materials upward along the inner wall of the mixing barrel through the screening plate to a position corresponding to the outside of the stirring paddle. The rotating shaft drives the stirring paddle to rotate, so that the stirring paddle swings out from the inside of the second holding tank and stirs the mixture of raw materials and water in the mixing barrel;

[0061] Step 3: Material transport process. The rotating shaft stops rotating, and the guide rod continues to drive the screening plate to move upward along the mixing barrel through the guide block. The guide block drives the slider upward through the adjustment spring, so that the slider hits the limit block. Then the screening plate moves upward relative to the upper cover, so that the lower end of the first crushing component contacts the upper end of the screening plate, and the crushing component is driven to move along the upper end of the screening plate to shovel and disperse the raw materials gathered in the original mixing dead corner;

[0062] Step 4: Secondary mixing process: the guide rod drives the screening plate to move downward to the position of the primary mixing process, and the shaft rotates again to perform secondary mixing on the dispersed raw materials;

[0063] Step 5, discharging process: After the secondary mixing process is completed, the guide rod drives the screening plate to move downward, so that the screening plate returns to the initial position, opens the discharge hopper, and puts the prepared raw materials in the mixing barrel into the aggregate frame.

[0064] The beneficial effects of the present invention are:

[0065] (1) The present invention prevents the raw materials from clogging the screening holes due to the inability of moisture to enter the raw materials when entering the mixing barrel, thereby reducing the fluidity of the raw materials in the mixing barrel during subsequent mixing.

[0066] (2) The present invention rotates the shaft at high speed, so that the stirring paddle originally located in the second holding tank rotates around the positioning shaft under the action of centrifugal force to the outside of the second holding tank and fully mixes the solidified raw materials close to the stirring paddle on the screening plate with water, and moves up and down through the screening holes, while the raw materials far away from the stirring paddle are accumulated on the upper part of the screening plate, thereby ensuring that the raw materials can be stirred within the largest stirring range during primary stirring, and the stirring efficiency is high.

[0067] (3) The present invention gathers and disperses the agglomerated raw materials through the extrusion action of the first extrusion teeth on the side of the first push block and the second extrusion teeth on the side of the second push block, thereby achieving the effect of extruding and dispersing the raw materials that are stirred evenly through the material mixing area, so that the raw materials that are solidified into agglomerates away from the stirring paddle can be dispersed after extrusion, thereby preventing uneven stirring inside the prepared coating.

[0068] (4) The present invention drives the stirring paddle out of the second holding tank under the action of centrifugal force by the rotating shaft, so that the dispersed raw materials are stirred for the second time, thereby switching the raw materials in small pieces after homogenization to the stirring zone for secondary stirring, ensuring that the raw materials can be stirred evenly and avoiding the inhibitory effect of stirring dead corners on stirring.

[0069] (5) The present invention provides a screening plate with screening holes at the bottom of the raw material, thereby ensuring that small particles after the raw material is completely dispersed can flow out of the area between the upper pressure cover and the screening plate along the screening holes, so that large particles that cannot pass through the screening holes after dispersion can be further stirred by the stirring paddle without being hindered by small particles, thereby accelerating the fluidity of the stirring process inside the mixing barrel.

[0070] (6) The present invention prepares granite coating by adopting the method of primary stirring process-material homogenization process-secondary stirring process, ensuring that the raw materials can be stirred within the maximum stirring range in the primary stirring process. For raw materials that are far away from the stirring paddle or are stuck together in a stirring dead angle, the present invention disperses the stuck raw materials through the material homogenization process and stirs them completely in the second stirring process, ensuring that the raw materials are stirred more fully.

[0071] In summary, the present invention has the advantages of good stirring effect, high preparation efficiency, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0122] a second pushing block 132 , which is disposed on a side opposite to the first pushing block 131 ;

[0123] The side of the first push block 131 is provided with a first extrusion tooth 1311 for extruding the screened raw materials;

[0124] The side of the second push block 132 is provided with a second extrusion tooth 1321 that matches the first extrusion tooth 1311;

[0128] The upper end of the first installation shaft 1312 is connected to a first rotating tooth 1313;

[0129] The first rotating teeth 1313 and the second rotating teeth 1323 are both engaged with the first driving mechanism 11423;

[0130] The first driving mechanism 11423 is preferably replaced by a motor.

[0131] As an improvement, Figure 9 As shown, the driving unit 2 includes:

[0132] Carrier 201;

[0133] A second driving mechanism 202, which is disposed above the carrier 201;

[0134] The second driving mechanism 202 is preferably replaced by a cylinder;

[0135] The upper portion of the second driving mechanism 202 is connected to a lifting arm 203;

[0136] One end of the lifting arm 203 is connected to a lifting plate 204 for controlling the lifting of the screening assembly 11;

[0137] The side of the second driving mechanism 202 is provided with a driving arm 205 for controlling the stirring assembly 12 to perform stirring work;

[0138] The driving arm 205 is provided with a servo motor for driving the rotating shaft 121 to rotate;

[0139] The lower part of the platform 201 is provided with a discharge hopper 206 connected to the interior of the mixing barrel 111;

[0140] An aggregate frame 207 for carrying the finished granite coating is provided below the discharge hopper 206 .

[0141] As an improvement, Figure 9 As shown, the feeding unit 3 includes:

[0142] Pre-stored box 301;

[0143] A push plate 302, a side of which is connected to a third driving mechanism 303;

[0144] The third driving mechanism 303 is preferably replaced by a cylinder;

[0145] It should be added that the push plate 302 of the present invention is located at one end of the mixing barrel 111 and is provided with an arc surface with the same arc as the mixing barrel 111, and a sealing gasket is provided between the push plate 302 and the mixing barrel 111 to prevent the raw materials in the mixing barrel 111 from flowing out along the gap between the mixing barrel 111 and the push plate 302 during the stirring process.

[0146] It should be added that the raw materials of liquid granite paint have a high viscosity, and generally a shorter stirring paddle 124 is required to rotate the raw materials in the mixing barrel 111 at high speed in order to mix the raw materials at the stirring point. However, the stirring range of the shorter stirring paddle 124 is limited. The raw materials in the mixing barrel 111 far away from the stirring paddle 124 are difficult to be stirred by the stirring paddle 124 due to their own adhesion. Therefore, it is necessary to manually disperse and clean the raw materials far away from the stirring paddle 124.

[0147] It should be noted that when in use, the raw materials are placed in the pre-storage frame 301, the third driving mechanism 303 is started, and the third driving mechanism 303 drives the pushing plate 302 to reciprocate once to push the raw materials in the pre-storage frame 301 into the mixing barrel 111 and between the screening plate 112 and the upper pressure cover 114, and a proper amount of water is poured into the mixing barrel 111 so that the water level is higher than the height of the stirring paddle 124, and the second driving mechanism 202 is started. Figure 3-4 As shown, the second driving mechanism 202 drives the lifting plate 204 to move upward via the lifting arm 203, and the lifting plate 204 drives the guide block 1121 to move upward along the guide rail 1112 via the guide rod 1122. The guide block 1121 drives the raw material upward via the screening plate 112, so that the raw material is sent to the area of ​​the stirring paddle 124;

[0148] During this process, the pre-blocking column 1111 is completely inserted into the screening hole 1123 and then separated from the screening hole 1123, so as to prevent moisture from entering the raw material when entering the mixing barrel 111, causing the raw material to block the screening hole 1123, resulting in the fluidity of the raw material in the mixing barrel 111 during subsequent mixing;

[0149] After the raw materials are fed into the stirring zone outside the stirring blade 124, Figure 4 As shown, the driving motor located in the driving arm 205 is started, and the driving motor drives the rotating shaft 121 to rotate at a high speed, so that the stirring paddle 124 originally located in the second receiving tank 1212 rotates around the positioning shaft 123 to the outside of the second receiving tank 1212 under the action of centrifugal force, and fully mixes the solidified raw materials near the stirring paddle 124 on the screening plate 112 with water, and reciprocates up and down through the screening hole 1123, while the raw materials farther away from the stirring paddle 124 accumulate on the upper part of the screening plate 112, thereby ensuring that the raw materials can be stirred within the maximum stirring range during the primary stirring, and the stirring efficiency is high;

[0150] The raw materials that are far away from the stirring blade 124 or have a dead angle for stirring and are not stirred are accumulated at the upper edge of the screening plate 112. At this time, the driving motor in the driving arm 205 is stopped to drive the rotating shaft 121 to rotate. Figure 5As shown, the stirring paddle 124 rotates around the positioning shaft 123 under the action of its own gravity and returns to the second receiving groove 1212. The second driving mechanism 202 is started again. The second driving mechanism 202 drives the lifting plate 204 to move upward through the lifting arm 203. The lifting plate 204 drives the guide block 1121 to move upward through the guide rod 1122. The guide block 1121 drives the screening plate 112 to move upward. At the same time, the guide block 1121 drives the slider 1141 to move upward to the limit block 1113 through the adjustment spring 113. As the guide block 1121 continues to drive the screening plate 112 upward, the guide rod 1122 slides relative to the slider 1141, and the adjustment spring 113 is compressed, so that the upper cover 114 stops moving upward, and the screening plate 112 moves upward relative to the upper cover 114 until the upper end of the screening plate 112 synchronously contacts the lower ends of the first push block 131 and the second push block 132, and the driving work of the second driving mechanism 202 stops. At this time, the bottom of the screening plate 112 is out of the water level in the mixing barrel 111, as shown in FIG. Figure 6-9 As shown, the first driving mechanism 11423 is started, and the first driving mechanism 11423 synchronously drives the second rotating tooth 1323 and the first rotating tooth 1313 to rotate in the opposite direction. The second rotating tooth 1323 drives the second push block 132 to rotate along the second guide rail 11422 through the second mounting shaft 1322, and the first rotating tooth 1313 drives the first push block 131 to rotate along the first guide rail 11421 through the first mounting shaft. The first push block 131 and the second push block 132 rotate in opposite directions against the edge of the upper surface of the screening plate 112. The primary stirring process is to scoop up the dispersed raw materials, and when the first pushing block 131 and the second pushing block 132 are about to contact, the first squeezing teeth 1311 on the side of the first pushing block 131 and the second squeezing teeth 1321 on the side of the second pushing block 132 are squeezed to gather and disperse the accumulated raw materials, thereby squeezing and dispersing the raw materials for uniform mixing in the material mixing area, so that the raw materials solidified into clumps away from the stirring paddle 124 can be dispersed after squeezing, thereby preventing uneven mixing inside the prepared coating.

[0151] After the extrusion and dispersion work is completed, the second driving mechanism 202 is started again. The second driving mechanism 202 drives the lifting plate 204 to move downward through the lifting arm 203. The lifting plate 204 drives the guide rod 1122 to move downward. The guide rod 1122 drives the screening plate 112 to move downward to the primary stirring area through the guide block 1121. Figure 4At this time, the driving motor in the driving arm 205 is started again, so that the driving motor drives the stirring paddle 124 through the rotating shaft 121 to rotate out of the second receiving tank 1212 under the action of centrifugal force, so that the dispersed raw materials are stirred for the second time, thereby achieving the goal of switching the raw materials in small pieces after homogenization to the stirring zone for secondary stirring, ensuring that the raw materials can be stirred evenly and avoiding the inhibitory effect of stirring dead corners on stirring.

[0152] It should be noted that, by providing a screening plate 112 with screening holes 1123 at the bottom of the raw material, the present invention can ensure that small particles of the raw material after being completely dispersed can flow out of the area between the upper pressure cover 114 and the screening plate 112 along the screening holes 1123. This allows large particles that cannot pass through the screening holes 1123 after dispersion to be further stirred by the stirring paddle 124 without being hindered by small particles, thereby accelerating the fluidity of the stirring process inside the mixing barrel 111.

[0153] It should be added that the various driving mechanisms of the present invention preferably use electrical signals to perform orderly control according to the preparation steps of the granite. After the secondary stirring is completed, the various components are reset to return to the initial position, the valve of the discharge hopper 206 is opened, and the raw materials enter the collection frame 207 along the discharge hopper 206 for collection.

[0154] Example 2

[0155] like Figure 10 As shown, the same or corresponding components as those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that the present invention further provides a system for preparing a weather-resistant liquid granite coating, which includes the following steps:

[0156] Step 1: Feeding process: put the raw materials into the pre-storage frame 301. The third driving mechanism 303 intermittently pushes the raw materials in the pre-storage frame 301 into the mixing barrel 111 filled with water through the pushing plate 302 and is located between the screening plate 112 and the upper pressure cover 114;

[0157] In step 2, during the primary mixing process, the guide rod 1122 drives the raw materials upward along the inner wall of the mixing barrel 111 through the screening plate 112 to a position corresponding to the outer portion of the stirring paddle 124. The rotating shaft 121 drives the stirring paddle 124 to rotate, causing the stirring paddle 124 to swing out from the inside of the second receiving tank 1212 and stir the mixture of raw materials and water in the mixing barrel 111.

[0158] Step 3: Material transport process: the rotating shaft 121 stops rotating, and the guide rod 1122 continues to drive the screening plate 112 to move upward along the mixing barrel 111 through the guide block 1121. The guide block 1121 drives the slider 1141 to move upward through the adjustment spring 113, so that the slider 1141 hits the limit block 1113. Then, the screening plate 112 moves upward relative to the upper cover 114, so that the lower end of the first crushing assembly 13 contacts the upper end of the screening plate 112, and the crushing assembly 13 is driven to move along the upper end of the screening plate 112 to shovel and disperse the raw materials gathered in the original mixing dead corner;

[0159] Step 4: Secondary stirring process: the guide rod 1122 drives the screening plate 112 to move downward to the position of the primary stirring process, and the rotating shaft 121 rotates again to perform secondary stirring on the dispersed raw materials;

[0160] Step 5, discharging process. After the secondary mixing process is completed, the guide rod 112 drives the screening plate 112 to move downward, so that the screening plate 112 returns to the initial position, opens the discharge hopper 206, and puts the prepared raw materials in the mixing barrel 111 into the aggregate frame 207.

[0161] It should be noted that the present invention prepares the granite coating by adopting a primary stirring process-a material homogenization process-a secondary stirring process, ensuring that the raw materials can be stirred within the maximum stirring range in the primary stirring process. For raw materials that are far away from the stirring paddle 124 or are stuck together in a stirring dead angle, the present invention disperses the stuck raw materials through the material homogenization process and completely stirs them in the secondary stirring process, ensuring that the raw materials are stirred more fully.

[0162] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
