Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, in particular to a mixing device for producing exterior wall real stone paint. Background Art

[0002] Real stone paint, also known as liquid stone, is a paint with a decorative effect similar to marble and granite, and has a certain viscosity. Real stone paint is mainly made of natural stone powder of various colors. According to the finishing effect, real stone paint can be divided into four categories: single-color real stone paint, multi-color real stone paint, rock flake real stone paint and imitation brick real stone paint. Real stone paint has the texture of natural stone, various grid designs, and can provide various three-dimensional pattern structures. It is an alternative to dry-hanging stone on exterior walls.

[0003] The mixing device is one of the key equipment in the production process of exterior wall real stone paint. The mixing device usually includes key components such as a base, a support plate, a mixing tank, and a driving device. Its working principle mainly relies on rotation and flipping motion. Driven by the driving device, the materials in the mixing tank continuously collide, rub and shear with each other during the rotation and flipping process, thereby achieving uniform mixing of the materials. Specifically: the base provides stable support for the entire device; the support plate is fixedly connected to the upper end face of the base to support the mixing tank; the mixing tank is used to hold and mix the raw materials of real stone paint, and its left and right ends are usually fixedly connected to support shafts, which are movably connected to the support plate through bearings, so that the mixing tank can rotate or flip within a certain range; the driving device includes motors, gears, racks, cylinders and other components for driving the rotation and flipping of the mixing tank, as well as realizing rapid material discharge, thereby saving time and manpower. The entire device has a compact and stable structure, which can ensure safety and reliability during the production process.

[0004] In the related art, solid raw materials and liquid raw materials for producing real stone paint are usually poured into a mixing tank, and the raw materials are stirred by a stirring device in the tank. However, the viscous liquid raw materials can easily wrap a mass of solid raw materials inside to form lumps, affecting the mixing effect, and thus easily affecting the uniformity and fineness of the real stone paint; therefore, it does not meet the existing needs.

Driven by the roller 140, a feed port 170 and a discharge port 180 are provided on the side of the conveying pipe 120. The feed port 170 is provided at the lower end of the conveying pipe 120, and the discharge port 180 is provided at the upper end of the conveying pipe 120. The discharge port 180 is located above the first grinding roller 140 and the second grinding roller 150. The mixed raw materials at the bottom of the tank body 100 are sent to the space between the first grinding roller 140 and the second grinding roller 150 by the screw conveyor 130 for grinding, and then continue to fall into the tank body 100.

[0043] The feed port 170 is opened at the lower end of the conveying pipe 120, and the discharge port 180 is opened at the upper end of the conveying pipe 120. The discharge port 180 is located above the first grinding roller 140 and the second grinding roller 150.

[0044] In this way, the raw materials are poured into the tank body 100, and the spiral agitator 110 is driven by the motor 133 to perform preliminary stirring of the raw materials. At the same time, the motor 133 also drives the screw conveyor 130 to rotate in the conveying pipe 120. Through the coordinated use of the screw conveyor 130 and the conveying pipe 120, the raw materials preliminarily stirred at the bottom of the tank body 100 are brought into the conveying pipe 120 through the feed port 170, and then sent to between the first grinding roller 140 and the second grinding roller 150 through the discharge port 180, and the first grinding roller 140 and the second grinding roller 150 are rotated relative to each other by the driving component 160 to squeeze and grind the raw materials to eliminate the lumps generated during the stirring of the raw materials. Subsequently, the ground raw materials fall into the tank body 100 again and are continuously stirred and ground, thereby improving the uniformity and fineness of the real stone paint.

[0045] In addition, the screw conveyor 130 includes a shaft 131 and a spiral belt 132 surrounding the outside of the shaft 131. The top of the conveying pipe 120 is fixedly connected to the inner wall of the tank body 100. The lower end of the shaft 131 passes through the bottom of the conveying pipe 120.

A reinforcement rod 136 is fixedly installed on the side of the spiral agitator 110. The end of the reinforcement rod 136 is fixedly connected to the outside of the reinforcement ring 135, thereby enhancing the stability of the spiral agitator 110.

[0046] Furthermore, the ends of the first grinding roller 140 and the second grinding roller 150 are rotatably arranged on the side of the tank body 100, the first grinding roller 140 is coaxially fixedly installed with a first gear 151, and the second grinding roller 150 is coaxially fixedly installed with a second gear 152. The first gear 151 and the second gear 152 are both located on the outside of the tank body 100, and the first gear 151 is meshed with the second gear 152.

[0047] Specifically, the upper end of the shaft 131 is rotatably inserted into the top of the tank body 100, and the driving assembly 160 includes a first rotating shaft 161 rotatably set on the top of the tank body 100, a second rotating shaft 162 rotatably set on the side of the tank body 100, and a transmission member 163 set between the shaft 131 and the first rotating shaft 161. The first rotating shaft 161 is set horizontally and the second rotating shaft 162 is set vertically. The shaft 131 drives the first rotating shaft 161 to rotate through the transmission member 163. A transmission member 163 is set between the first rotating shaft 161 and the second rotating shaft 162, and a transmission member 163 is also set between the second rotating shaft 162 and the first grinding roller 140.

[0048] The drive assembly 160 also includes a fixed pile 164 arranged on the outside of the tank body 100. The number of the fixed piles 164 is set to be several. The first rotating shaft 161 is rotatably inserted into one end of the fixed pile 164, and the other end of the fixed pile 164 is fixedly connected to the top of the tank body 100. Similarly, the second rotating shaft 162 is also rotatably inserted into one end of the fixed pile 164, and the other end of the fixed pile 164 is fixedly connected to the side wall of the tank body 100, thereby supporting the first rotating shaft 161 and the second rotating shaft 162.

[0049] In other embodiments, in an embodiment where a transmission member 163 is provided between the shaft 131 and the first rotating shaft 161, Figure 10 As shown, the transmission member 163 includes a first bevel gear 1631 installed at the end of the shaft 131, a second bevel gear 1632 installed at one end of the first rotating shaft 161 and meshing with the first bevel gear 1631, a first pulley 165 installed at the other end of the first rotating shaft 161, a second pulley 166 coaxially installed with the first gear 151, and a conveyor belt 167 jointly sleeved between the first pulley 165 and the second pulley 166. The shaft 131 drives the first rotating shaft 161 to rotate through the engagement of the first bevel gear 1631 and the second bevel gear 1632, and the first rotating shaft 161 drives the first pulley 165 to rotate. Then, through the transmission action of the conveyor belt 167, the second pulley 166 drives the first gear 151 and the first grinding roller 140 to rotate.

[0050] In addition, the second grinding roller 150 includes a roller core 200 arranged on the side of the first grinding roller 140, an insertion shaft 201 coaxially fixedly installed at both ends of the roller core 200, and a shell 202 sleeved on the outside of the insertion shaft 201, one of the shells 202 is coaxially fixedly connected to the second gear 152, and the other shell 202 is rotatably arranged on the side wall of the tank body 100 through a bearing.

[0051] An elastic ring 210 is fixedly installed on the inside of the shell 202, and the elastic ring 210 is set to a rubber ring. The plug-in shaft 201 is fixedly fitted with the inner ring of the elastic ring 210, and the inner wall of the shell 202 is fixedly fitted with the outer ring of the elastic ring 210. An elastic membrane 211 is provided at the joint between the plug-in shaft 201 and the shell 202, and the elastic membrane 211 is set to a rubber membrane. The middle part of the elastic membrane 211 surrounds the outside of the plug-in shaft 201, and the outside of the elastic membrane 211 is fixedly connected to the side wall of the shell 202, thereby sealing the joint between the plug-in shaft 201 and the shell 202 to prevent real stone paint from entering the shell 202.

[0052] A fixing ring 212 is provided on the middle part of the plug shaft 201, and the fixing ring 212 is arranged on the outside of the shell 202. A protrusion 213 is fixedly installed on the outside of the fixing ring 212. A limiting ring 214 is provided on the outside of the fixing ring 212. The limiting ring 214 is fixedly arranged in the tank body 100. A support rod is fixedly installed on the outside of the limiting ring 214. The other end of the support rod is fixedly installed on the inner wall of the tank body 100. A limiting groove 215 for use with the protrusion 213 is provided on the inner ring of the limiting ring 214. The number of the limiting grooves 215 is set to several, and the several limiting grooves 215 are equidistantly arranged in the annular direction. The protrusion 213 is intermittently inserted into the limiting ring 214. The roller core 200 is fixed with a counterweight core 216, and the center of the counterweight core 216 is on a different straight line from the center of the roller core 200, and the counterweight core 216 is close to the side of the protrusion 213. The density of the counterweight core 216 is greater than the density of the roller core 200, so that the center of gravity of the second grinding roller 150 is biased toward the side where the counterweight core 216 is located. When the roller core 200 is stationary, the center of the insertion shaft 201 and the center of the limiting ring 214 are on the same horizontal line, and at this time the protrusion 213 is located in one of the limiting grooves 215.

[0053] Through the above technical solution, when the mixing device for producing exterior wall real stone paint provided by the present disclosure is in use, the motor 133 drives the shaft 131 to rotate, so that the shaft 131 drives the spiral stirrer 110 to rotate through the connecting rod 134, thereby preliminarily stirring the raw materials in the tank body 100. At the same time, the motor 133 also drives the screw conveyor 130 to rotate in the conveying pipe 120 through the shaft 131. Through the cooperation of the screw conveyor 130 and the conveying pipe 120, the raw materials preliminarily stirred at the bottom of the tank body 100 are brought into the conveying pipe 120 through the feed port 170, and then delivered to between the first grinding roller 140 and the second grinding roller 150 through the discharge port 180;

[0054] At the same time, the shaft 131 also drives the first bevel gear 1631 to rotate. Through the meshing of the first bevel gear 1631 and the second bevel gear 1632, the second bevel gear 1632 drives the first rotating shaft 161 to rotate. The first rotating shaft 161 drives the second rotating shaft 162 to rotate through the use of the transmission member 163. Similarly, the second rotating shaft 162 also drives the first grinding roller 140 to rotate through the use of the transmission member 163, and drives the first gear 151 to rotate. At this time, through the meshing of the first gear 151 and the second gear 152, the first grinding roller 140 and the second grinding roller 150 rotate relative to each other, thereby squeezing and grinding the raw materials and eliminating lumps generated during the mixing of the raw materials.

[0055] Moreover, when the second gear 152 drives the plug shaft 201 and the roller core 200 to rotate through the housing 202, the roller core 200 deviates in the direction of the counterweight core 216 due to the centrifugal force caused by the counterweight core 216, and the plug shaft 201 squeezes the elastic ring 210, causing the elastic ring 210 to deform but still support the plug shaft 201. The plug shaft 201 drives the fixed ring 212 to rotate, causing the protrusion 213 to intermittently conflict with the inner wall of the limit ring 214, or causing the protrusion 213 to slide into the limit groove 215. When the protrusion 213 conflicts with the inner wall of the limit ring 214, the protrusion 213 Under the action of the thrust of the limiting ring 214 by 213, the roller core 200 is offset to the side away from the counterweight core 216, and the elastic ring 210 is squeezed. When the protrusion 213 slides into the limiting groove 215, the centrifugal force of the counterweight core 216 and the rebound force of the elastic ring 210 cause the roller core 200 to reset to the side close to the counterweight core 216, so that the roller core 200 can achieve an oscillation effect while rotating, further breaking and grinding the lumps. Subsequently, the ground raw materials fall into the tank body 100 again, and are continuously stirred and ground, thereby improving the uniformity and fineness of the real stone paint.

[0056] It should be noted that the side of the tank body 100 is provided with a feed pipe for feeding raw materials and a discharge pipe for discharging the real stone paint product. This is a well-known and commonly used technical means and will not be described in detail here.

[0057] In some embodiments, a transmission member 163 is provided between the shaft 131 and the first rotating shaft 161. Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown in , the transmission member 163 includes a first bevel gear 1631 and a second bevel gear 1632, and the first bevel gear 1631 and the second bevel gear 1632 are meshed with each other. In the first pair of transmission members 163: the first bevel gear 1631 is interference mounted on the top of the shaft 131, and the second bevel gear 1632 is interference mounted on one end of the first rotating shaft 161; in the second pair of transmission members 163: the first bevel gear 1631 is interference mounted on the top of the second rotating shaft 162, and the second bevel gear 1632 is interference mounted on the other end of the first rotating shaft 161; in the third pair of transmission members 163: the first bevel gear 1631 is interference mounted on the bottom of the second rotating shaft 162, and the second bevel gear 1632 is coaxially fixedly mounted with the first grinding roller 140.

[0058] In some embodiments of the present disclosure, reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown in the figure, a movable piece 190 is movably provided inside the tank body 100, and the movable piece 190 is located above the first grinding roller 140 and the second grinding roller 150. A straight rod 191 is fixedly installed on the upper side of the movable piece 190, and a slide rod 192 is installed on the upper end of the straight rod 191. The middle part of the slide rod 192 is slidably inserted into the upper side of the tank body 100, and a disc 193 is fixedly installed in the middle of the first rotating shaft 161. A track groove 194 is opened on the side of the disc 193, and a limiting slider 195 is fixedly installed on the top of the slide rod 192. The limiting slider 195 is slidably inserted in the track groove 194, and the limiting slider 195 is set to a sphere to prevent the limiting slider 195 from falling out of the track groove 194.

[0059] The track groove 194 includes a first groove 1941 and a second groove 1942 connected to the first groove 1941 . The first groove 1941 and the second groove 1942 together form an annular groove, and the center of the annular groove does not coincide with the center of the first rotating shaft 161 .

[0060] The movable piece 190 has different position states.

[0061] For example, in some embodiments, reference Figure 5 、 Figure 6 and Figure 9 As shown, the movable sheet 190 can have a first state, which is the state when the movable sheet 190 is not in use. In the first state, the movable sheet 190 is located above the first grinding roller 140 and the second grinding roller 150, and maintains a certain distance from the first grinding roller 140 and the second grinding roller 150.

[0062] For example, in some embodiments, reference Figure 7 and Figure 8 As shown, the movable sheet 190 can have a second state, which is the state when the movable sheet 190 is in use. In the second state, the movable sheet 190 drops between the first grinding roller 140 and the second grinding roller 150, and is close to the junction of the first grinding roller 140 and the second grinding roller 150.

[0063] Next, the present disclosure will provide a detailed introduction to the movable sheet 190 in combination with the above specific embodiments. Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown in , when the first grinding roller 140 and the second grinding roller 150 rotate relative to each other, the first rotating shaft 161 drives the disc 193 to rotate half a circle, so that the limiting slider 195 slides in the first groove 1941. Through the cooperation between the limiting slider 195 and the first groove 1941, the slide bar 192 drives the movable plate 190 to descend between the first grinding roller 140 and the second grinding roller 150 through the straight rod 191, so as to facilitate downward squeezing of the raw material agglomerates accumulated between the first grinding roller 140 and the second grinding roller 150;

[0064] Then, the disc 193 continues to rotate half a circle, so that the limiting slider 195 slides in the second groove 1942, and the movable piece 190 is driven to move up and reset through the slide rod 192. In summary, through the up and down reciprocating movement of the movable piece 190, the raw material agglomerates accumulated between the first grinding roller 140 and the second grinding roller 150 are continuously squeezed downward, so that the first grinding roller 140 and the second grinding roller 150 crush and grind the raw material agglomerates, improve the grinding effect, thereby improving the mixing efficiency of the real stone paint and improving the fineness of the real stone paint.
