[0021] The present invention will be further described below with reference to the accompanying drawings: The directional nouns involved in the paragraphs with detailed descriptions are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, terms such as "arranged", "installed", "connected", etc. should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] As Figures 1 to 12 shown, the mixing device for producing striped mixed-color blocks includes a mixing support assembly 4, and the mixing support assembly 4 serves as the support foundation and moving guiding frame for the entire mixing device. A moving material receiving frame 2 capable of moving along its length direction is provided on the mixing support assembly 4. A mixing conveying mechanism 3 is fixedly connected to the lower part of the moving material receiving frame 2. The conveying direction of the mixing conveying mechanism 3 is parallel to the length direction of the mixing support assembly 4. A plurality of storage mechanisms 1 capable of moving back and forth are provided on the upper part of the moving material receiving frame 2. The moving direction of the storage mechanism 1 is perpendicular to the conveying direction of the mixing conveying mechanism 3. Since the position of the feeding port 5 is fixed, the moving material receiving frame 2 can drive a plurality of storage mechanisms 1 to automatically receive materials of different colors respectively. Then, through the coordinated cooperation of the storage mechanism 1 and the mixing conveying mechanism 3, materials of different colors are stacked in sequence. In this process, the width and proportional relationship of the stacking of materials of different colors can be controlled, thereby providing a basis for the customization of striped mixed-color blocks.

[0023] Specifically, as Figure 1 and Figure 10 shown, the mixing support assembly 4 includes a bottom frame 401. The bottom frame 401 is welded by steel frames to ensure that the equipment can withstand various loads during operation and maintain overall stability. A ladder 403 is welded and fixed on the bottom frame 401. Operators can climb onto the bottom frame 401 through the ladder 403 and perform maintenance on the mixing device. On both sides of the upper end of the bottom frame 401, moving guide rails 402 for guiding the movement of the moving material receiving frame 2 are respectively fixedly connected. The surface of the moving guide rail 402 is hardened, reducing the friction coefficient and improving the smoothness and guiding accuracy of the movement of the moving material receiving frame 2. On the inner sides of the upper part of the bottom frame 401, moving racks 404 are respectively fixedly connected. The moving racks 404 cooperate with the moving gears 208 on the moving material receiving frame 2 to provide a guiding and power transmission path for the movement of the moving material receiving frame 2.

[0024] As Figure 8 and Figure 9As shown in the figure, the mobile material receiving rack 2 includes a mobile rack 201. At least two groups of mobile wheels 203 are rotatably connected to both sides of the bottom of the mobile rack 201. The mobile wheels 203 are rotatably matched with the mobile guide rails 402, thereby assisting the entire mobile material receiving rack 2 to move back and forth. One end of the mobile rack 201 is fixedly connected with a mobile motor 204. This mobile motor 204 is a double-shaft motor, preferably fixedly installed in the middle of the mobile rack 201. The two-way output of power is realized through the double-shaft motor, improving the power transmission efficiency. The output end of the mobile motor 204 is connected with a mobile gear 208. Specifically, the two output shafts of the double-shaft motor are respectively connected with speed reducers 206 through universal couplings 205. Among them, the universal coupling 205 can compensate for the angular deviation caused by installation errors and during the working process, ensuring stable power transmission; the speed reducer 206 can adjust the speed and torque according to actual needs. The mobile gear 208 is fixedly installed at the output end of the speed reducer 206. The mobile gear 208 meshes with the mobile rack 404, thereby realizing the precise movement of the mobile material receiving rack 2 along the length direction of the mixing support assembly 4.

[0025] As Figure 4 and Figure 5 As shown in the figure, the storage mechanism 1 includes a hopper support frame 104, a traveling power mechanism 106, and a feeding and conveying mechanism 107. A storage bin 101 is fixedly connected to the hopper support frame 104. The storage bin 101 adopts a conical hopper design, which is convenient for the smooth sliding of materials. Reinforcing angle irons 102 are respectively welded and fixed on both sides of the storage bin 101. Traveling wheels 103 are rotatably connected to the reinforcing angle irons 102 through fixed seats. A traveling guide rail 202 that is in rolling cooperation with the traveling wheels 103 is fixedly connected to the upper part of the mobile rack 201 of the mobile material receiving rack 2, enabling the traveling wheels 103 to freely roll along the traveling guide rail 202; a transmission shaft 105 is rotatably connected to the hopper support frame 104. The traveling power mechanism 106 drives the transmission shaft 105 to rotate. Traveling gears 1051 are respectively arranged at both ends of the transmission shaft 105. A traveling rack 207 that meshes with the traveling gears 1051 is fixedly connected to the mobile rack 201 of the mobile material receiving rack 2. The traveling gears 1051 mesh with the traveling rack 207, thereby realizing the back-and-forth movement of the storage mechanism 1 on the mobile material receiving rack 2, and the moving direction of the storage mechanism 1 is perpendicular to the moving direction of the mobile material receiving rack 2 on the mixing support assembly 4.

[0026] The feeding and conveying mechanism 107 is arranged at the bottom of the storage bin 101. The feeding and conveying mechanism 107 is used to achieve precise feeding of materials. As Figure 5 and Figure 6As shown in the figure, the blanking conveying mechanism 107 includes a blanking conveying motor 108, a first driving shaft 1072 and a first driven shaft 1071. The blanking conveying motor 108 is fixedly connected to the hopper support frame 104. The first driving shaft 1072 and the first driven shaft 1071 are respectively rotatably connected to the hopper support frame 104 through bearings. A first conveyor belt is commonly driven and connected by the first driving shaft 1072 and the first driven shaft 1071. The blanking conveying motor 108 drives the first driving shaft 1072 to rotate. Specifically, sprockets that match each other are fixedly installed at the output end of the blanking conveying motor 108 and one end of the first driving shaft 1072, and the two sprockets are connected by a chain drive. Starting the blanking conveying motor 108 can drive the first conveyor belt to operate, realizing the conveying and blanking of materials.

[0027] To ensure the stable operation of the first conveyor belt, a first idler support 1073 and a first conveyor belt retaining rod 1075 are fixedly connected to the hopper support frame 104. The quantities of the first idler support 1073 and the first conveyor belt retaining rod 1075 are determined according to the length of the first conveyor belt. A first conveyor belt idler 1074 for supporting and limiting the first conveyor belt is rotatably connected to the first idler support 1073. The first conveyor belt retaining rod 1075 is in limit fit with the side end of the first conveyor belt, effectively preventing the first conveyor belt from running off track.

[0028] As Figure 11 and Figure 12 As shown in the figure, the mixing and conveying mechanism 3 includes a conveying frame 301 and a conveying driving mechanism 307. Both the conveying frame 301 and the conveying driving mechanism 307 are fixedly connected to the movable material receiving frame 2. A second driven shaft 302 and a second driving shaft 306 are rotatably connected to the conveying frame 301. A second conveyor belt is commonly driven and connected by the second driven shaft 302 and the second driving shaft 306. Sprockets that match each other are fixedly connected to the output end of the conveying driving mechanism 307 and one end of the second driving shaft 306, and the two sprockets are connected by a chain drive. Starting the conveying driving mechanism 307, the conveying driving mechanism 307 can drive the second driving shaft 306 to rotate, thereby driving the second conveyor belt to convey, so as to stably convey materials.

[0029] Multiple groups of second idler supports 305 and second conveyor belt retaining rods 303 are fixedly connected to the conveying frame 301. A second conveyor belt idler 304 for supporting and limiting the second conveyor belt is rotatably connected to the second idler support 305. The second conveyor belt retaining rod 303 is in limit fit with the side end of the second conveyor belt, preventing the second conveyor belt from running off track. The mixing and conveying mechanism 3 realizes the unified conveying of the materials blanked by different storage mechanisms 1 to the next process (the cloth feeding system) for cloth feeding.

[0030] The color mixing method for producing striped multi-color blocks, using the above-mentioned mixing device for producing striped multi-color blocks, includes the following steps: S1. Since the position of the blanking port 5 is fixed and the blanking port 5 is connected to the mixer, after the mixer has stirred the first coloring material well, start the moving motor 204. The moving motor 204 outputs power with a double shaft. Through the transmission of the universal coupling 205 and the speed reducer 206, it drives the moving gear 208 to mesh and rotate with the moving rack 404, thereby driving the moving material receiving frame 2 and the storage mechanism 1 to move towards the blanking port 5. After the blanking port 5 is aligned with the feeding end of one of the storage mechanisms 1, the blanking port 5 is opened, and the coloring material is injected into the corresponding storage bin 101. After the material injection is completed, the mixer starts self-cleaning, and then stirs the first coloring material. Working in such a cycle, the blanking port 5 injects materials of different colors into multiple storage mechanisms 1 respectively. Until all the storage mechanisms 1 have completed receiving materials, the moving motor 204 rotates in reverse, driving the moving material receiving frame 2 and the storage mechanism 1 to reset to the initial position, preparing for subsequent mixing.

[0031] S2. Multiple storage mechanisms 1 move for blanking in sequence, and the moving blanking process is as follows: The traveling power mechanism 106 and the blanking conveying motor 108 on the first storage mechanism 1 are started. The traveling power mechanism 106 drives the transmission shaft 105 to rotate, making the traveling gear 1051 mesh with the traveling rack 207, driving the first storage mechanism 1 to move back and forth above the mixing and conveying mechanism 3; at the same time, the blanking port of the storage bin 101 is opened, and the blanking conveying motor 108 drives the first driving shaft 1072 to rotate, driving the first conveyor belt to run. The coloring material evenly falls onto the first conveyor belt. The first conveyor belt drives and then evenly conveys the coloring material onto the second conveyor belt of the blanking conveying mechanism 3. The driving directions of the first conveyor belt and the second conveyor belt are perpendicular. By setting the first conveyor belt and the second conveyor belt, the uniform laying of the coloring material is realized. Until the first storage mechanism 1 has completed blanking, the corresponding traveling power mechanism 106 resets, and at the same time, the traveling power mechanism 106 and the blanking conveying motor 108 stop working.

[0032] S3. The conveying driving mechanism 307 on the mixing and conveying mechanism 3 is started. The conveying driving mechanism 307 drives the second driving shaft 306 to rotate, driving the second conveyor belt to move the coloring material after the first storage mechanism 1 has blanked to the lower part of the second storage mechanism 1. At this time, repeat the blanking process in step 2, so that the second storage mechanism 1 places the material on the upper part of the coloring material of the first blanking. By precisely controlling the moving speed and blanking time of each storage mechanism 1, the thickness of different coloring materials can be adjusted, thereby realizing the adjustment of the width of the block stripes and the color ratio, and ensuring the flat stacking between layers and the stripe mixing effect.

[0033] S4. Repeat step 3, and in accordance with the preset mixing sequence and parameters, control the remaining storage mechanisms 1 to carry out blanking in sequence until all the storage mechanisms 1 have completed blanking. At this time, multiple color materials are stacked layer by layer on the second conveyor belt.

[0034] S5. Start the conveying drive mechanism 307 again. The conveying drive mechanism 307 drives the second conveyor belt to rotate, and the second conveyor belt feeds the stacked materials into the cloth feeding system at a stable speed for cloth feeding, thereby realizing the precise color mixing of the striped color-mixed blocks.

[0035] In the cloth feeding system, through the cooperation of the cloth feeding vehicle and the main machine, the materials are further compacted and evenly distributed, and finally the striped color-mixed blocks meeting the design requirements are produced.

[0036] Finally, although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

The conveying driving mechanism (307) on the mixing and conveying mechanism (3) is started to drive the conveyor belt two to move the materials after the first storage mechanism (1) discharges them to the lower part of the second storage mechanism (1), and repeat the discharging process in step 2 to enable the second storage mechanism (1) to discharge the materials on the upper part of the previous discharging. S4. Repeat step 3 until all the storage mechanisms (1) have finished discharging materials. At this time, a variety of materials are stacked on the conveyor belt two. S5. Start the conveying driving mechanism (307) again. The conveying driving mechanism (307) drives the conveyor belt two to convey. The conveyor belt two sends the stacked materials into the cloth conveying system for cloth conveying, thus realizing the color mixing of the striped color - mixed blocks.
