Description

Technical Field

[0001] This invention relates to the field of eco-stone production equipment technology, and in particular to an eco-stone dry multi-color batching and distribution system. Background Technology

[0002] Eco-stone is a new type of decorative material that uses existing industrial solid waste or mine tailings as its main raw materials and employs a non-fired molding process to achieve patterns and textures similar to natural stone or other specific materials. Eco-stone retains the noble and elegant qualities of natural stone while overcoming common defects such as pores, cracks, color variations, and radioactivity. Given these advantages, eco-stone is widely favored and has a promising market prospect.

[0003] With the continuous development of society and the economy, people have increasingly higher requirements for the natural-looking effects and textures of eco-stone products. Currently, the preparation of eco-stone typically involves batching and spreading processes. Multiple single-color powders are combined in a certain proportion using a feeding device to form a mixed powder. Then, a spreading device distributes the powder into a mold as required, and finally, it is pressed and cured to form the eco-stone. To achieve richer and more natural textures and patterns, multiple mixed powders and multiple spreading processes are usually required. However, the existing feeding and spreading equipment are separate devices. Furthermore, after batching, the feeding device requires an additional mixer to further mix the single-color powders. Then, multiple mixed powders are transported to different spreading stations via conveyor belts for spreading, resulting in low production efficiency.

[0004] Furthermore, existing eco-stone material preparation and distribution systems typically employ a feeding device, a feeding assembly, a stirring rod, and a pushing rod. The feeding device dispenses powders of different colors into the feeding assembly, where they are mixed. Rotating the stirring rod creates different textures, and the pushing rod further agitates the mixture, allowing for variable and special textures in the eco-stone. Because existing material distribution equipment primarily controls the feeding speed of the feeding device and shapes patterns by rotating the stirring and pushing rods, the resulting eco-stone often only exhibits continuous linear textures such as diagonal or wavy lines, or granite-like patterns. This results in limited color variety, unnatural textures, and difficulty in creating natural-looking patchy patterns. The resulting eco-stone rarely replicates the textures of natural stone, exhibiting a relatively poor natural-looking effect. Summary of the Invention

[0005] The purpose of this invention is to propose a dry multi-color material distribution system for eco-stone, which can automatically distribute the material, improve production efficiency, and form an irregular patchy decorative effect with rich colors and textures throughout, thus solving the current problems of low production efficiency, limited color variety, and unnatural textures in eco-stone production.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An eco-friendly dry process multi-color batching and distribution system for stone includes, from top to bottom, a powder dispersing device, a feeding device, a distribution device, and a mold conveying device for conveying molds;

[0008] The material delivery equipment includes a mounting frame and several chain-driven transfer hoppers. The transfer hoppers are slidably mounted on the top of the mounting frame, and are arranged side by side along the width of the mounting frame. The mounting frame is equipped with several chain drive devices, one of which drives a transfer hopper to slide along the length of the mounting frame. The bottom of the mounting frame is equipped with several unloading stations, each unloading station having several receiving hoppers. The receiving hoppers at the same unloading station are located below the travel path of the transfer hoppers.

[0009] The powder dispersing device includes several powder dispersing components. The discharge end of the powder dispersing device is located above the loading station of the transfer hopper. The powder dispersing components are used to load the dispersed color material into the transfer hopper. The transfer hopper is used to transport the color material to the receiving hopper of the designated unloading station.

[0010] The fabric-laying equipment includes a frame and several fabric-laying units. The several fabric-laying units are installed side by side and spaced apart on the frame. The several fabric-laying units are respectively located above the mold conveying equipment and below the several unloading stations.

[0011] The fabric feeding unit includes several fabric feeding hoppers, several discharge belts, a collection belt, a collection hopper, a briquetting belt, a briquetting device, a rotary cutter, and a discharge toothed plate. Several fabric feeding hoppers are arranged side by side on the frame. Each fabric feeding hopper has a discharge belt below its discharge port, and several discharge belts are respectively arranged above the collection belts. One fabric feeding hopper is located below a receiving hopper, and the position of the discharge port of the receiving hopper corresponds to the position of the inlet of the fabric feeding hopper.

[0012] The collecting hopper is located below the collecting belt, and the feeding port of the collecting hopper corresponds to the end of the collecting belt in the conveying direction. The briquetting belt is located below the collecting hopper, and the briquetting device is installed above the briquetting belt. The briquetting device is used to pre-press the mixed powder on the briquetting belt into flakes.

[0013] A rotary cutter is provided above the end of the conveying direction of the briquetting belt. The rotary cutter is used to cut the sheet-like mixed powder into strips. The discharge toothed plate is provided at the end of the conveying direction of the briquetting belt. The cut strip-shaped powder falls into the mold through several teeth of the discharge toothed plate.

[0014] Furthermore, the pressing device includes a drive cylinder and a pressing plate, the drive cylinder is connected to the frame, and the telescopic end of the drive cylinder is connected to the pressing plate;

[0015] The rotary cutter includes a rotating shaft and several circular blades, with the circular blades spaced apart and fitted onto the rotating shaft.

[0016] Connectors are provided on the left and right sides of the rotating shaft, and support frames that cooperate with the connectors are provided on the left and right sides of the pressure block belt. The connectors can be installed on the support frames in an adjustable manner.

[0017] Furthermore, the discharge toothed plate has a number of teeth connected in sequence on the side near the pressing belt, and the number of teeth has different sizes and shapes;

[0018] A recess is provided between two adjacent teeth, and the teeth and the recess are smoothly transitioned. The distance between the tips of adjacent teeth in a plurality of teeth is different, and the teeth are arc-shaped or corner-shaped.

[0019] Furthermore, the material delivery equipment also includes several gate opening devices, several gate closing devices, and several opening and closing components;

[0020] The bottom of the transfer hopper is provided with a discharge port, and several opening and closing components are respectively installed at the bottom of several transfer hoppers. The opening and closing components are used to block and open the discharge port.

[0021] The opening and closing assembly includes a sliding frame and a gate. The gate is fixedly installed in the middle of the sliding frame, and a discharge space is formed between the end of the gate and the end of the sliding frame. Both ends of the sliding frame have the discharge space.

[0022] The sliding frame is slidably installed at the bottom of the transfer hopper, and the sliding frame slides so that the gate and the discharge hole correspond to the positions of the discharge port respectively; the receiving hopper is located below the travel trajectory of the sliding frame;

[0023] The gate opening device is vertically and can be installed on the mounting frame. The installation positions of several gate opening devices correspond to the installation positions of several receiving hoppers. When the gate opening device is raised, it blocks the sliding frame that is moving, so that the discharge port moves from the gate plate to the discharge space, and the color material in the transfer hopper is discharged into the receiving hopper.

[0024] Several gate-closing devices are mounted on the mounting frame in a liftable manner, and the positions of the gate-closing devices correspond one-to-one with the positions of the discharge ends of the powder dispersing components. When the gate-closing devices are raised, they block both sides of the sliding frame and drive the transfer hopper to move through the chain drive device, so that the discharge port moves from the discharge space to the gate plate for loading.

[0025] Furthermore, the gate opening device includes a first tilting seat, a first tilting arm, and a first lifting cylinder. The first tilting seat is connected to the mounting frame. One end of the first tilting arm is hinged to the first tilting seat, and a first blocking block is fixedly installed on the other end of the first tilting arm. The first lifting cylinder is located below the first tilting arm, and the telescopic end of the first lifting cylinder corresponds to the position of the first tilting arm.

[0026] The first tilting seat, the first tilting arm, and the first lifting cylinder are respectively located below the travel path of the sliding frame. When the extension end of the first lifting cylinder is in the retracted state, the first tilting arm is tilted downward, causing the first blocking block to descend below the travel path of the sliding frame. When the extension end of the first lifting cylinder is in the extended state, the first lifting cylinder drives the first tilting arm to rise, causing the first blocking block to rise. The position of the first blocking block after it rises corresponds to the position of the sliding frame, so that the first blocking block after it rises blocks the sliding frame.

[0027] Furthermore, the gate opening device also includes a first angle limiting frame, which is in the shape of an inverted "U". The opening of the first angle limiting frame is fixedly installed on the first flipping seat with its opening facing downwards, and the end of the first flipping arm near the first flipping seat is accommodated in the first angle limiting frame.

[0028] The first angle limiting frame is located below the walking trajectory of the sliding frame.

[0029] Furthermore, the gate closing device includes two gate closing components arranged in a mirror-symmetrical manner. The two gate closing components are respectively connected to the mounting frame in a lifting manner, and the two gate closing components are respectively arranged on the left and right sides of the discharge end of the powder dispersing component. The two gate closing components are respectively used to block the two sides of the sliding frame, so that the position of the sliding frame is fixed. The transfer hopper is driven to move by the chain drive device, so that the discharge port moves from the discharge space to the gate.

[0030] The gate closing assembly includes a second tilting seat, a second tilting arm, a second lifting cylinder, a second blocking block, and a connecting plate. The second tilting seat is connected to the mounting frame. One end of the second tilting arm is hinged to the second tilting seat, and the other end of the second tilting arm is connected to the connecting plate. The second blocking block is mounted on the connecting plate. The second lifting cylinder is mounted on the mounting frame and is located below the second tilting arm.

[0031] The blocking end of the second blocking block faces the second flip base, and the blocking end of the second blocking block is equipped with a sensor;

[0032] The second tilting seat, the second tilting arm, and the second lifting cylinder are respectively located below the travel path of the sliding frame. When the extension end of the second lifting cylinder is in the retracted state, the second tilting arm is tilted downward, causing the second blocking block to descend below the travel path of the sliding frame. When the extension end of the second lifting cylinder is in the extended state, the second lifting cylinder drives the second tilting arm to rise, causing the second blocking block to rise. The position of the second blocking block after it rises corresponds to the position of the sliding frame, so that the second blocking block after it rises blocks one side of the sliding frame.

[0033] The distance between the two second blocking blocks located in the two gate assemblies after they rise corresponds to the length of the sliding frame, so that the two second blocking blocks after rising are used to block the two sides of the sliding frame respectively.

[0034] Furthermore, guide wheels are installed on both sides of the feed port, the rotation axis of the guide wheels is vertically arranged relative to the sliding frame, and the wheel surface of the guide wheels is provided with guide grooves;

[0035] Both sides of the sliding frame are fixedly provided with first guide bars, and the two first guide bars extend into the guide grooves of the guide wheel respectively;

[0036] Limiting strips are provided at both ends of the sliding frame.

[0037] Furthermore, the fabric unit also includes several first adjustment mechanisms and several second adjustment mechanisms, and the two sides of the discharge belt can be adjusted and installed on both sides of the frame through the first adjustment mechanisms;

[0038] The first adjustment mechanism includes a first adjustment screw and a first locking member. One end of the first adjustment screw is fixedly installed on the frame, and the other end of the first adjustment screw is connected to the discharge belt. The first adjustment screw is arranged vertically, and the first adjustment mechanism is used to adjust the installation height of the discharge belt.

[0039] The two sides of the collecting belt are adjustablely mounted on both sides of the frame via the second adjustment mechanism, and the collecting belt is located below the discharge belt. The second adjustment mechanism is used to adjust the installation height of the collecting belt.

[0040] The second adjustment mechanism includes a second adjusting screw and a second locking member. One end of the second adjusting screw is fixedly installed on the frame. Both sides of the material collection belt are respectively provided with connecting parts that cooperate with the second adjusting screw. The other end of the second adjusting screw is connected to the connecting part of the material collection belt. The material collection belt can move up and down along the height direction of the second adjusting screw. The second locking member is used to fix the connecting part.

[0041] Furthermore, the chain drive device includes a transmission chain assembly and a load-bearing wheel assembly; the transmission chain assembly includes a transmission chain bracket, a transmission motor, and a transmission chain, the transmission chain being mounted on the transmission chain bracket; the transmission motor is driven and connected to the transmission chain.

[0042] The transfer hopper is provided with a fixed base on its exterior, and the fixed base is fixedly installed with the transmission chain;

[0043] The bearing wheel assembly includes a plurality of bearing wheels and a bearing rail parallel to the transmission chain bracket; the plurality of bearing wheels are mounted on the side of the fixed base away from the transmission chain, and the bearing wheels roll along the bearing rail;

[0044] The transfer hopper also includes a guide assembly, which includes a longitudinal guide wheel and a transverse guide wheel. The longitudinal guide wheel is mounted on a fixed base by a bracket. The shaft of the longitudinal guide wheel is vertically arranged, and the wheel surface of the longitudinal guide wheel is in contact with the side wall of the transmission chain bracket.

[0045] The transverse guide wheel is mounted on the fixed base by a mounting component, and the transverse guide wheel is located below the bearing wheel. The shaft of the transverse guide wheel is arranged transversely. The bottom end of the bearing track is provided with a second guide bar, which is arranged along the extension direction of the bearing track. The wheel surface of the transverse guide wheel and the second guide bar cooperate with each other.

[0046] The above technical solution has the following beneficial effects: This ecological stone dry-process multi-color batching and distribution system, by sequentially arranging the powder dispersing equipment, feeding equipment, distribution equipment, and mold conveying equipment from top to bottom, effectively saves equipment floor space and shortens material transportation distance, thereby improving production efficiency. Furthermore, after batching through three transfer hoppers, this technical solution allows for direct mixing of individual color powders (i.e., colorants) and pre-processing of the mixed powders on the distribution equipment before final distribution. This eliminates the need for an additional mixer to mix individual color powders, further improving production efficiency. Furthermore, this technical solution incorporates a briquetting device, a rotary cutter, and a discharge toothed plate within the fabric feeding equipment. The briquetting device mixes powder and presses it into sheet form. The pressed sheet powder is in a basically shaped state. After being cut by the rotary cutter, it forms strip powder. The strip powder is then dispersed by the discharge toothed plate into small pieces of varying sizes and irregular shapes, which are irregularly distributed on the mold. After subsequent pressing and molding, a natural, irregular patchy pattern is formed on the surface of the eco-stone, making the surface pattern and texture of the resulting eco-stone more consistent with the pattern and texture of natural stone, resulting in a better natural imitation effect.

[0073] The following is combined Figures 1 to 17 This invention describes an embodiment of an eco-stone dry-process multi-color batching and distribution system.

[0074] An eco-friendly dry process multi-color batching and spreading system for stone includes, from top to bottom, a powder dispersing device C, a feeding device B, a spreading device A, and a mold conveying device A2 for conveying molds;

[0075] The material delivery equipment B includes a mounting frame B5 and several transfer hoppers B1. The transfer hoppers B1 are slidably mounted on the top of the mounting frame B5 and are arranged side by side along the width of the mounting frame B5. The mounting frame B5 is equipped with several chain drive devices B7, and each chain drive device B7 is used to drive a transfer hopper B1 to slide along the length of the mounting frame B5. The bottom of the mounting frame B5 is equipped with several unloading stations B51, and each unloading station B51 is equipped with several receiving hoppers B511. The receiving hoppers B511 located at the same unloading station B51 are located below the travel path of the transfer hoppers B1.

[0076] The material dispensing equipment C includes several powder dispersing components C1. The discharge end of the powder dispersing component C1 is located above the moving trajectory of the transfer hopper B1. Each transfer hopper B1 moves on a specific conveying channel. Each transfer hopper B1 has a loading station in its corresponding conveying channel. The discharge end of the powder dispersing component C1 is located above the loading station. The powder dispersing component C1 is used to load the dispersed color material into the transfer hopper. The transfer hopper is used to convey the color material to the receiving hopper B511 at the designated unloading station.

[0077] The fabric feeding device A includes a frame A1 and several fabric feeding units A3. The several fabric feeding units A3 are installed side by side and spaced apart on the frame A1. The several fabric feeding units are respectively located above the mold conveying device, and the several fabric feeding units A3 are respectively located below the several unloading stations B51.

[0078] The fabric feeding unit A3 includes several fabric feeding hoppers A31, several discharge belts A32, a collection belt A33, a collection hopper A34, a briquetting device A35, a briquetting belt A36, a rotary cutter A37, and a discharge toothed plate A38. The several fabric feeding hoppers A31 are installed side by side on the frame A1. Each fabric feeding hopper A31 has a discharge belt A32 below its discharge port. The several discharge belts are respectively located above the collection belts. One fabric feeding hopper A31 is located below a receiving hopper B511, and the position of the discharge port of the receiving hopper B511 corresponds to the position of the inlet of the fabric feeding hopper A31.

[0079] The collecting hopper A34 is located below the collecting belt A33, and the feeding port of the collecting hopper A34 corresponds to the end of the conveying direction of the collecting belt A33. The briquetting belt A36 is located below the collecting hopper A34, and the briquetting device A35 is installed above the briquetting belt A36. The briquetting device A35 is used to pre-press the mixed powder on the briquetting belt A36 into flakes.

[0080] A rotary cutter A37 is provided above the end of the conveying direction of the briquetting belt A36. The rotary cutter A37 is used to cut the pre-pressed mixed powder into strips. The end of the conveying direction of the briquetting belt A36 is connected to a discharge toothed plate A38. The cut strips of powder fall into the mold through several teeth of the discharge toothed plate A38.

[0081] It is worth noting that the ecological stone dry process multi-color batching and distribution system of this technical solution, by arranging the powder dispersing device C, the feeding device B, the distribution device A, and the mold conveying device A2 sequentially from top to bottom, can effectively save the equipment's floor space and shorten the material transportation distance, thereby improving production efficiency. This technical solution involves sliding several transfer hoppers B1 on the top of the mounting frame B5, and several unloading stations B51 at the bottom of the mounting frame B5. Below each unloading station B51 is a corresponding distribution unit A3. Simultaneously, several powder dispersing components C1 are located above the feeding device B, each transporting a single color powder. By selecting one or more of the single-color powders from the transfer hoppers B1 for combination and batching, various mixed powders can be obtained. Specifically, several transfer hoppers B1 each transport a selected color material (which can be the same color or different colors) to different receiving hoppers B511 at the unloading station B51 for batching. This completes the batching process. In this technical solution, each transfer hopper B1 has an independent conveying channel, allowing it to reach each unloading station B51, thus ensuring that the batching processes of several transfer hoppers B1 do not interfere with each other. Since the unloading station B51 is located above the material distribution unit A3, and the outlet of the receiving hopper B511 corresponds to the inlet of the material distribution hopper A31, the material in the transfer hoppers B1 can directly enter the material distribution hopper A31 through the receiving hopper B511. It is then mixed via the collecting belt A33 to obtain a mixed powder. After pre-pressing by the briquetting device A35, the mixed powder is cut by the rotary cutter A37 and finally falls from the discharge toothed plate A38 into the mold, completing the material distribution. This technical solution completes the batching process through multiple transfer hoppers B1, allowing for direct mixing of various colored materials and pre-processing of the mixed powder in the spreading equipment A before spreading. This eliminates the need for an additional mixer to mix single-color powders, thereby further improving production efficiency.

[0082] Furthermore, this technical solution involves setting up a briquetting device A35, a rotary cutter A37, and a discharge toothed plate A38 in the fabric feeding equipment A. The briquetting device A35 can mix powder and press it into a sheet shape. The pressed sheet powder is in a basically shaped state. After the rotary cutter A37 cuts the sheet powder into strips, the strips fall into the mold through several teeth of the discharge toothed plate A38. Because the distribution and shape of the teeth of the discharge toothed plate A38 are irregular, the strips of powder can be staggered and irregularly distributed on the mold. Furthermore, because the discharge toothed plate A38 has irregular teeth... The dry-toothed material has relatively sharp tips, and the strip-shaped powder is in a basically shaped state (i.e., the powder is not very firm). When the powder is fed through several teeth of the discharge plate A38, some of the strip-shaped powder will be dispersed when it touches the tips of the teeth, forming small pieces of irregular size and shape. After being pressed and shaped later, it forms a very natural, irregular patch pattern on the surface of the eco-stone, making the surface pattern and texture of the eco-stone more in line with the pattern and texture of natural stone, and the imitation of nature is better. This solves the problem that it is difficult to form imitation natural patch patterns on the surface of eco-stone using existing material feeding equipment.

[0083] Preferably, the material distribution equipment B of this technical solution is equipped with three transfer hoppers B1 and three chain drive devices B7, each unloading station B51 is equipped with three receiving hoppers B511, the material distribution unit A3 includes three material distribution hoppers A31 and three discharge belts A32, and the material distribution equipment C includes four powder dispersing components C1. In the process of preparing eco-stone, in order to enhance the natural-looking effect of the eco-stone, it is usually necessary to use a variety of different colorants. By mixing these different colorants, various mixed powders are obtained. These mixed powders are then distributed, and the desired color and texture patterns are formed on the mold after distribution. The material delivery equipment B in this technical solution is equipped with three transfer hoppers B1, and the material laying unit A3 of the material laying equipment A is equipped with three material laying hoppers A31. The three colored materials are transported separately to the three receiving hoppers B511 of the same unloading station B51 via the three transfer hoppers B511. From the receiving hoppers B511, the materials fall into the three material laying hoppers A31 of the same material laying unit A3. The three colored materials are then conveyed to the corresponding discharge belts A32 via different material laying hoppers A31. The discharge belts A32 then transport the three colored materials... The colorant spills into the collecting belt A33 located below the discharge belt A32. The three colorants are stacked on the collecting belt A33, and then conveyed to the collecting hopper A34 for further mixing. The mixture then falls through the discharge port of the collecting hopper A34 onto the briquetting belt A36. Since a briquetting device A35 is installed above the briquetting belt A36, the mixed powder continues to be conveyed to the briquetting device A35 via the briquetting belt A36. At the position corresponding to 5 below, the briquetting device A35 presses downwards to pre-press the mixed powder into flakes. After pressing, the briquetting belt A36 continues to convey the flakes of mixed powder to the end of the conveying direction of the briquetting belt A36. Since a rotary cutter A37 is provided at the end of the conveying direction of the briquetting belt A36, the rotary cutter A37 cuts the flakes of mixed powder into strips. The strips of powder fall onto the mold through the discharge toothed plate A38. It is irregular. Based on the pressure of the briquetting device A35, the pressed sheet powder is in a basically shaped state. When it passes through the discharge toothed plate A38, it will be dispersed by the ends of the teeth of the discharge toothed plate A38 into small sheet materials of different sizes and irregular shapes, which are irregularly distributed on the mold. After being pressed and shaped later, a very natural irregular patch pattern is formed on the surface of the ecological stone, making the surface pattern and texture of the ecological stone more in line with the pattern and texture of natural stone, and the imitation natural effect is better.

[0084] It is worth noting that the material-laying equipment A in this technical solution includes several material-laying units 2. By using several material-laying units 2, multiple material-laying operations can be performed sequentially, which can enrich the texture and pattern of the resulting eco-stones to meet people's needs.

[0085] Preferably, the powder dispersing component C1 is a belt conveyor that drops the material into the transfer hopper B1 via the belt.

[0086] Further explanation: The pressing device A35 includes a drive cylinder A351 and a pressing plate A352. The drive cylinder A351 is connected to the frame A1, and the telescopic end of the drive cylinder A351 is connected to the pressing plate A352.

[0087] The rotary cutter A37 includes a rotating shaft A371 and several circular blades A372, with the several circular blades A372 spaced apart and fitted onto the rotating shaft A371;

[0088] Connectors A373 are provided on the left and right sides of the rotating shaft A371, and support frames A361 that cooperate with the connectors A373 are provided on the left and right sides of the pressure block belt A36. The connectors A373 can be installed on the support frames A361 in an adjustable manner.

[0089] Specifically, the briquetting device A35 of this technical solution includes a drive cylinder A351 and a pressure plate A352. The pressure plate A352 is horizontally positioned above the briquetting belt A36. One end of the drive cylinder A351 is fixedly mounted to the frame, and the telescopic end of the drive cylinder A351 is connected to the pressure plate A352. When the telescopic end of the drive cylinder extends outward, it drives the pressure plate A352 to press downward, pre-pressing the mixed powder into a sheet shape. After pressing, the telescopic end of the drive cylinder retracts inward, completing the pressing process, and the mixed powder is pressed into a sheet shape. This technical solution adjusts the pressure of the pressure plate on the mixed powder by changing the extension speed of the drive cylinder's telescopic end. The pressure can be adjusted to achieve the desired pattern effect. For example, when a smaller patchy pattern is desired, the extension speed of the drive cylinder's telescopic end can be reduced, resulting in less pressure from the pressure plate A352 on the mixed powder. This leads to a lower density of the pressed flakes, making them easier to disperse when discharged through the discharge toothed plate A38, forming smaller flakes. The resulting ecological stone product will have a smaller patchy pattern, or even just small spots. Similarly, increasing the extension speed of the drive cylinder's telescopic end increases the pressure of the pressure plate on the mixed powder. This results in a denser, more compact flake that is less easily dispersed. After being cut by the rotary cutter A37 and discharged through the discharge toothed plate A38, larger flakes will form, resulting in a larger patchy pattern on the surface of the final ecological stone product.

[0090] Furthermore, other conventional methods in the art can also be used to adjust the pressure of the pressure plate A352 when pressing the mixed powder.

[0091] Specifically, in this technical solution, the rotary cutter A37 is equipped with a rotating shaft A371 and circular blades A372. The circular blades A372 are spaced apart from the rotating shaft A371. By rotating the rotary cutter A37, the rotating circular blades A372 can cut the sheet-like mixed powder. Since there is a certain gap between two adjacent circular blades A372, the sheet-like mixed powder can be cut into strips. In this technical solution, by changing the distance between two adjacent circular blades A372, the size of the strip-shaped powder obtained after cutting can be further adjusted.

[0092] It is worth noting that, through the cooperation of connector A373 and support frame A361, this technical solution allows the rotary cutter A37 to be installed vertically and vertically above the briquetting belt A36 to reach the required cutting height, thereby enabling better cutting of flaky mixed powder.

[0093] It is worth noting that in this technical solution, a motor is used to drive the rotary cutter A37 to rotate, thereby cutting the sheet-like powder.

[0094] The upper part of the support frame A361 is provided with a guide groove A3611, and the left and right ends of the rotating shaft A371 pass through two connectors A373 respectively and are located inside the corresponding guide grooves A3611.

[0095] The top of the connector A373 is laterally provided with a mounting plate on the side closer to the support frame A361. The rotary cutter A37 also includes an adjusting bolt A374. The top of the adjusting bolt A374 is fixedly connected to the mounting plate, and the bottom of the adjusting bolt A374 is adjustablely mounted on the support frame A361.

[0096] It is worth noting that, based on the fixed connection between the top of the adjusting bolt A374 and the mounting plate in this technical solution, the bottom of the adjusting bolt A374 is adjustablely mounted on the top of the support frame A361. By rotating the bolt, the connecting piece A373 can be moved up and down. Based on the fixed connection between the rotating shaft A371 and the connecting piece A373, the rotating shaft A371 can be moved up and down, thereby adjusting the height of the rotary cutter A37. Simultaneously, a connecting bolt can be installed on the connecting piece A373. The connecting bolt is horizontally positioned, with one end fixedly connected to the connecting piece A373 and the other end horizontally passing through the support frame A361. After adjusting the height of the rotary cutter A37, a lock nut is used to fix the position of the connecting bolt, thereby more securely mounting the rotary cutter A37 above the pressure belt A36.

[0097] To further explain, the discharge toothed plate A38 has several teeth A381 connected in sequence on the side near the briquetting belt A36, and the size and shape of the teeth A381 are different.

[0098] There is a recess between two adjacent teeth A381, and the tooth A381 and the recess are smoothly transitioned. The distance between the tops of adjacent teeth A381 in a number of teeth A381 is different, and the teeth A381 are arc-shaped or corner-shaped.

[0099] It is worth noting that the size and shape of each tooth A381 on the discharge plate A38 of this technical solution are different. Some teeth are longer, some are shorter, some are wider, and some are narrower. This causes the strip-shaped powder to fall irregularly and disperse in the mold when it passes through the teeth A381. Furthermore, since the strip-shaped powder of this technical solution is in a basically shaped state (i.e., the strip structure is not very strong), when the strip-shaped powder touches the end of the tooth A381 during discharge, some of the strip-shaped powder is easily dispersed by the end of the tooth A381. Due to the weight of the powder itself, some of the strip-shaped powder will also be scattered due to impact when it falls into the mold, thus forming small pieces of varying sizes and irregular shapes, which are irregularly dispersed in the mold. This increases the randomness and irregularity of the pattern in the product, making the overall surface effect more natural.

[0100] It is worth noting that this technical solution uses the teeth A381 and the recesses, and makes the spacing between the teeth A381 and the shape of the teeth A381 different, so that the powder can be distributed in the mold in an irregular state with different shapes and sizes, thus making the resulting ecological stone product present a more natural imitation natural patch pattern.

[0101] Further explanation: the material delivery equipment B also includes several gate opening devices B2, several gate closing devices B3, and several opening and closing components B4.

[0102] The bottom of the transfer hopper B1 is provided with a discharge port B11, and several opening and closing components B4 are respectively installed at the bottom of several transfer hoppers B1. The opening and closing components B4 are used to block and open the discharge port B11.

[0103] The opening and closing assembly B4 includes a sliding frame B41 and a gate B42. The gate B42 is fixedly installed in the middle of the sliding frame. A discharge space B43 is formed between the end of the gate B42 and the end of the sliding frame B41. Both ends of the sliding frame B41 have discharge spaces B43.

[0104] The sliding frame B41 is slidably installed at the bottom of the transfer hopper B1. The sliding frame B41 slides so that the gate B42 and the discharge hole B43 correspond to the positions of the discharge port B11 respectively; the receiving hopper B511 is located below the travel path of the sliding frame B41.

[0105] The gate opening device B2 is mounted on the mounting frame B5 in a height-adjustable manner, and the installation positions of several gate opening devices B2 correspond to the installation positions of several receiving hoppers B511 respectively, so that when the gate opening device B2 is raised, it blocks the moving sliding frame B41, and the discharge port B11 moves from the gate plate B42 to the discharge space B43.

[0106] Several gate-closing devices B3 are mounted on the mounting frame B5 in a height-adjustable manner, and the positions of the gate-closing devices B3 correspond one-to-one with the positions of the discharge ends of the powder dispersing components C1. When the gate-closing devices B3 are raised, they block both sides of the sliding frame B41. The chain drive device B7 drives the transfer hopper B1 to move, so that the discharge port B11 moves from the discharge space B43 to the gate plate B42.

[0107] It is worth noting that this technical solution does not include a power mechanism for opening and closing the discharge port B11 on the transfer hopper B1. Instead, it uses a non-powered opening and closing component B4, making the overall weight of the transfer hopper B1 lighter and reducing the requirements for the chain drive device. With the same drive power, the transfer hopper B1 achieves higher material dispensing efficiency. Furthermore, since this technical solution does not include a drive component on the transfer hopper B1 (i.e., it does not include a cylinder or servo motor to drive the discharge port B11 to open or close), the gate opening device B2 and gate closing device B3 are mounted on the mounting frame B5. This makes the movement of the transfer hopper B1 smoother, prevents electrical wires and air supply lines from interfering with the movement of the transfer hopper B1, and reduces the control difficulty of the entire material dispensing equipment.

[0108] Specifically, this solution has a sliding frame B41 installed at the bottom of the discharge port B11 of the transfer hopper B1. The sliding frame B41 has two discharge slots B43 and a gate B42 that blocks the discharge port B11. When loading, the gate B42 of the sliding frame B41 is located below the discharge port B11, blocking the discharge port B11. At the same time, since the opening and closing component B4 does not have a power mechanism, during the material transportation process, the transfer hopper B1 drives the opening and closing component B4 to move synchronously, so that the discharge port B11 is always blocked during the material transportation process to prevent the material from falling during the transportation process. When discharging, one of the discharge slots B43 of the sliding frame B41 corresponds to the position of the discharge port B11, that is, the discharge port B11 is opened, allowing the material in the transfer hopper B1 to flow out.

[0109] The principle of the opening and closing component B4 in this technical solution for blocking and opening the discharge port B11 is as follows: The opening and closing component B4 includes a sliding frame B41 and a gate B42. The gate B42 is fixedly installed in the middle of the sliding frame. A discharge space B43 is formed between the end of the gate B42 and the end of the sliding frame B41. Both ends of the sliding frame B41 have discharge spaces B43. Since the sliding frame B41 is slidably installed at the bottom of the transfer hopper B1, when the position of the discharge port B11 corresponds to the position of the gate B42, the discharge port B11 is blocked and can be used for receiving and transporting materials; when the position of the discharge port B11 corresponds to the discharge space B43, the discharge port B11 is opened, and the material in the transfer hopper B1 can be unloaded into the designated receiving hopper B511. After the transfer hopper B1 receives material, the position of the discharge port B11 corresponds to the position of the gate B42, thus blocking the discharge port B11. The chain drive device then transports the transfer hopper B1 to the designated unloading station B51, where the receiving hopper B511 is located. During the movement of the transfer hopper B1, the sliding frame B41 moves synchronously with the transfer hopper B1, ensuring that the discharge port B11 remains blocked. A gate opening device B2 is located on one side of the receiving hopper B511. When the sliding frame B41 approaches the receiving hopper B511, the gate opens... The gate device B2 rises upward, blocking the sliding frame B41 and stopping its movement. At this time, the transfer hopper B1 continues to move, driven by the chain drive device, causing displacement between the transfer hopper B1 and the sliding frame B41, making it impossible to maintain synchronous movement. Driven by the chain drive device, the discharge port B11 moves from the position of the gate plate B42 to the discharge empty position B43, opening the discharge port B11. The material in the transfer hopper B1 falls through the discharge port B11 to the designated receiving hopper B511, completing the discharge. After the material is unloaded, the chain drive device B7 drives the transfer hopper B1 to move below the powder dispersing component C1, preparing for the next material receiving. Since the gate device B3 is vertically mounted on the mounting frame B5, and its position corresponds to that of the powder dispersing component C1, when the transfer hopper B1 moves to the position corresponding to the powder dispersing component C1, the gate device B3 rises, blocking both sides of the sliding frame B41 and fixing its position. At this point, the chain drive device stops, and the transfer hopper B1 continues to move forward due to inertia. The transfer hopper B1 moves until it contacts the end of the sliding frame B41, at which point it stops moving. At this point, the position of the discharge port B11 corresponds to the discharge empty space B43. The chain drive device drives the transfer hopper B1 to move in the opposite direction, so that the discharge port B11 moves from the discharge empty space B43 to the gate plate B42. The discharge port B11 is blocked, and the gate closing device B3 descends, so that the material in the powder dispersing component C1 can be sprinkled into the transfer hopper B1. After the material is loaded, the chain drive device can continue to drive the transfer hopper B1 to move until it reaches the designated receiving hopper B511.

[0110] It is worth noting that several gate opening devices B2 located below the travel trajectory of the same transfer hopper B1 are respectively located on the side of the corresponding receiving hopper B511 away from its corresponding powder dispersing component C1. That is, when the receiving hopper B511 is on the left side of the powder dispersing component C1, the gate opening device B2 is set on the left side of the receiving hopper B511, and when the receiving hopper B511 is on the right side of the powder dispersing component C1, the gate opening device B2 is set on the right side of the receiving hopper B511, so that the raised gate opening device B2 can block the moving sliding frame B41.

[0111] Further explanation: The gate opening device B2 includes a first tilting seat B21, a first tilting arm B22, and a first lifting cylinder B23. The first tilting seat B21 is connected to the mounting bracket B5. One end of the first tilting arm B22 is hinged to the first tilting seat B21, and the other end of the first tilting arm B22 is fixedly mounted with a first blocking block B24. The first lifting cylinder B23 is located below the first tilting arm B22, and the telescopic end of the first lifting cylinder B23 corresponds to the position of the first tilting arm B22.

[0112] The first tilting seat B21, the first tilting arm B22, and the first lifting cylinder B23 are located below the travel path of the sliding frame B41. When the telescopic end of the first lifting cylinder B23 is in the retracted state, the first tilting arm B22 is tilted downward, causing the first blocking block B24 to descend below the travel path of the sliding frame B41. When the telescopic end of the first lifting cylinder B23 is in the extended state, the first lifting cylinder B23 drives the first tilting arm B22 to rise, causing the first blocking block B24 to rise. The position of the first blocking block B24 after rising corresponds to the position of the sliding frame B41, so that the first blocking block B24 blocks the sliding frame B41 after rising.

[0113] This technical solution uses a gate opening device B2 to cause relative displacement between the sliding frame B41 and the transfer hopper B1, thereby achieving the effect of opening the valve. The gate opening device B2 includes a first tilting seat B21, a first tilting arm B22, and a first lifting cylinder B23. When one end of the sliding frame B41 approaches the receiving hopper B511, the telescopic end of the first lifting cylinder B23 lifts upward, causing the first blocking block B24 to move upward. The upward-moving first blocking block B24 can prevent the sliding frame B41 from moving further. At this time, the transfer hopper B1 will continue to move towards the receiving hopper B511 under the drive of the chain drive device until the discharge port moves from the gate plate B42 to the discharge empty position B43, so that the discharge port B11 is opened, thereby allowing the material in the transfer hopper B1 to flow out and completing the discharge.

[0114] It is worth noting that in this technical solution, the first tilting seat B21, the first tilting arm B22, and the first lifting cylinder B23 are all located below the travel path of the sliding frame B41. At the same time, when the telescopic end of the first lifting cylinder B23 is in the retracted state, since the first tilting arm B22 is hinged to the first tilting seat B21, the first tilting arm B22 naturally tilts downward under the action of gravity, abutting against the telescopic end of the first lifting cylinder B23, causing the entire first blocking block B24 to descend below the travel path of the sliding frame B41. At this time, the entire gate opening device B2 is located below the travel path of the sliding frame B41. Therefore, when the telescopic end of the first lifting cylinder B23 is in the retracted state, the entire gate opening device B2 does not affect the movement of the transfer hopper B1. When the transfer hopper B1 reaches the designated receiving hopper B511, the telescopic end of the first lifting cylinder B23 corresponding to the designated receiving hopper B511 extends upward. Driven by the first lifting cylinder B23, the first tilting arm B22 rises upward, driving the first blocking block B24 to rise upward. Based on the position of the first blocking block B24 after it rises and the position of the sliding frame B41's travel trajectory, the first blocking block B24 after rising can block the moving sliding frame B41, causing the sliding frame B41 to stop moving. At this time, driven by the chain drive device, the transfer hopper B1 and the sliding frame B41 move relative to each other. The transfer hopper B1 moves on the sliding frame B41, causing the discharge port B11 to move from the gate plate B42 to the discharge empty position B43 for material discharge. Therefore, when the first blocking block B24 in the gate opening device B2 of this technical solution is in the descending state, the entire gate opening device B2 does not affect the movement of the transfer hopper B1. When the first blocking block B24 rises, it can block the sliding frame.

[0115] To further explain, after the gate opening device B2 rises, it blocks the sliding frame B41. At this time, when the moving sliding frame B41 comes into contact with the blocking block, it will impact the gate opening device B2. The use of the first tilting arm B22 combined with the first tilting seat B21, which has a strong load-bearing structure, improves the reliability and maintainability of the equipment.

[0116] Further explanation: the gate opening device B2 also includes a first angle limiting frame B25, which is in the shape of an inverted "U". The opening of the first angle limiting frame B25 is fixedly installed on the first flipping seat B21 with the opening facing downward. The end of the first flipping arm B22 near the first flipping seat B21 is accommodated in the first angle limiting frame B25.

[0117] The first angle limiting frame B25 is located below the travel trajectory of the sliding frame B41.

[0118] The first angle limiting frame B25 of this technical solution is used to constrain the flipping angle of the first flipping arm B22. By limiting the flipping angle of the first flipping arm B22, the position of the first blocking block B24 after it is raised corresponds to the position of the sliding frame B41's travel trajectory. This ensures that the first blocking block B24 can block the sliding frame B41 and prevents the first flipping arm B22 from failing to block the sliding frame B41 due to an excessively large flipping angle.

[0119] Further explanation: The gate closing device B33 includes two gate closing components B31 arranged in a mirror symmetrical manner, and the two gate closing components B31 are respectively connected to the mounting frame B5 in a lifting manner, and the two gate closing components B31 are respectively arranged on the left and right sides of the discharge end of the powder dispersing component C1; the two gate closing components B31 are respectively used to block the two sides of the sliding frame B41, so that the position of the sliding frame B41 is fixed, and the transfer hopper B1 is driven to move through the chain drive device, so that the discharge port B11 moves from the discharge hole B43 to the gate plate B42;

[0120] The gate closing assembly B31 includes a second tilting seat B311, a second tilting arm B312, a second lifting cylinder B313, a second blocking block B314, and a connecting plate B315. The second tilting seat B311 is connected to the mounting bracket B5. One end of the second tilting arm B312 is hinged to the second tilting seat B311, and the other end of the second tilting arm B312 is connected to the connecting plate B315. The second blocking block B314 is installed on the connecting plate B315. The second lifting cylinder B313 is installed on the mounting bracket B5 and is located below the second tilting arm B312.

[0121] The blocking end of the second blocking block B314 faces the second flip seat B311, and the blocking end of the second blocking block B314 is equipped with a sensor.

[0122] The second tilting seat B311, the second tilting arm B312, and the second lifting cylinder B313 are respectively located below the travel path of the sliding frame B41. When the extension end of the second lifting cylinder B313 is in the retracted state, the second tilting arm B312 is tilted downward, causing the second blocking block B314 to descend below the travel path of the sliding frame B41. When the extension end of the second lifting cylinder B313 is in the extended state, the second lifting cylinder B313 drives the second tilting arm B312 to rise, causing the second blocking block B314 to rise. The position of the second blocking block B314 after rising corresponds to the position of the sliding frame B41, so that the second blocking block B314 after rising blocks one side of the sliding frame B41.

[0123] The distance between the two second blocking blocks B314 located in the two gate assemblies B31 after they are raised corresponds to the length of the sliding frame B41, so that the two second blocking blocks B314 after being raised can block the two sides of the sliding frame B41 respectively.

[0124] It is worth noting that this technical solution achieves the effect of closing the discharge port B11 through the cooperation of the gate closing device B3 and the chain drive device. The gate closing device B3 includes two gate closing components B31 arranged in a mirror-symmetrical manner. The gate closing components B31 are respectively installed on the mounting frame B5 and located on the left and right sides below the powder dispersing component C1. When the transfer hopper B1 needs to receive material, the transfer hopper B1 moves towards the powder dispersing component C1. When the transfer hopper B1 approaches the powder dispersing component C1, the gate closing component B31 on the side away from the transfer hopper B1 rises, blocking one side of the sliding frame B41. At this time, driven by the chain drive device B7, the transfer hopper B1 continues to move until the end of the transfer hopper B1 contacts the sliding frame B41. At this time, the other gate closing component B31 rises (because a sensor is provided at the blocking end of the second blocking block B314, when the sensor senses...). After being struck twice, another symmetrically positioned gate assembly B31 rises, blocking the other side of the sliding frame B41. Alternatively, the control program can be configured so that when the sliding frame B41 touches the gate assembly B31, the other symmetrically positioned gate assembly B31 rises, blocking the other side of the sliding frame B41. This blocks both ends of the sliding frame B41, fixing its position. Then, the chain drive device moves the transfer hopper B1, causing the discharge port B11 to move from the discharge empty position B43 to the gate plate B42, thus closing the discharge port B11, allowing it to be used for receiving and conveying materials.

[0125] This technical solution achieves the closing effect through the cooperation of two gate-closing components B31 and the driving action of a chain drive device. Since both gate-closing components B31 are mounted on the mounting frame B5, they do not need to be installed on the transfer hopper B1, effectively reducing the load on the transfer hopper B1 and simplifying its structure, resulting in faster and less disruptive transportation. Furthermore, the gate-opening device B2, the two gate-closing components B31, and the chain drive device are all electrically connected to the PLC automatic control system, enabling automatic opening and closing of the discharge port B11.

[0126] Specifically, the two gate-closing components B31 of this technical solution are installed on the mounting frame B5 and located on the left and right sides below the powder dispersing component C1. The mounting frame B5 is equipped with photoelectric sensors. When the photoelectric sensors detect that the sliding frame B41 has entered the position corresponding to the powder dispersing component C1, they transmit the information to the PLC automatic control system. The PLC automatic control system then transmits the information to the gate-closing component B31 located in front of the sliding frame B41's travel path. The extension end of the second lifting cylinder B313 of the gate-closing component B31 rises, driving the second tilting arm B312 to rise, thereby driving the second blocking block B314 to rise. When the sliding frame B41 moves to the position corresponding to the second blocking block B314, the second blocking block B314 blocks one end of the moving sliding frame B41. Furthermore, when one end of the sliding frame B41 touches the area in front of the sliding frame B41's travel path... After the gate assembly B31 is closed, the second lifting cylinder B313 of the gate assembly B31, located behind the sliding frame B41's travel trajectory, extends upward, lifting the second tilting arm B312 and causing the second blocking block B314 to rise and block the other end of the sliding frame B41. At this time, both ends of the sliding frame B41 are limited by the two gate assemblies B31, fixing the position of the sliding frame B41. When the chain drive device drives the transfer hopper B1 to travel on the sliding frame B41 and contacts the front end of the sliding frame B41, the transfer hopper B1 stops moving forward. At this time, the position of the discharge port B11 of the transfer hopper B1 corresponds to the discharge empty space B43. Then, the PLC automatic control system controls the chain drive device to drive the transfer hopper B1 to retreat until the position corresponding to the moving gate plate B42 of the discharge port B11 is reached, and the discharge port B11 is blocked by the gate plate B42, that is, the discharge port B11 is closed.

[0127] It is worth noting that, relative to the position of the powder dispersing component C1, some receiving hoppers B511 are located on the left side of the powder dispersing component C1, while others are located on the right side. Therefore, when the transfer hopper B1 discharges material and returns to the powder dispersing component C1 to receive material, it may move from the left side of the powder dispersing component C1 towards the powder dispersing component C1, or it may move from the right side of the powder dispersing component C1 towards the powder dispersing component C1. Since the two gate components B31 in this technical solution are arranged in a mirror symmetrical manner, the gate device B3 of this technical solution can adapt to the above two situations, and can block and limit the sliding frame B41, thereby moving the discharge port B11 to the discharge empty space B43 to the gate plate B42, achieving the purpose of closing the discharge port B11.

[0128] Further explanation: the gate assembly B31 also includes a second angle limiting frame B316, which is in the shape of an inverted "U". The opening of the second angle limiting frame B316 is fixedly installed on the second flip base B311 with the opening facing downward. The end of the second flip arm B312 near the second flip base B311 is accommodated in the second angle limiting frame B316.

[0129] The second angle limit frame B316 is located below the travel trajectory of the sliding frame B41.

[0130] It is worth noting that this technical solution sets a second angle limiting frame B316 on the gate assembly B31. The second angle limiting frame B316 can constrain the flipping angle of the second flipping arm B312 to ensure that the position of the second blocking block after it is raised corresponds to the position of the sliding frame B41's travel trajectory. This ensures that the second blocking block B314 can complete the blocking and limiting of the sliding frame B41, and prevents the second flipping arm B312 from failing to block and limit the sliding frame B41 due to an excessively large flipping angle.

[0131] To further explain, guide wheels B6 are installed on both sides of the discharge port B11. The rotating shaft of the guide wheel B6 is vertically arranged relative to the sliding frame B41, and the wheel surface of the guide wheel B6 is provided with a guide groove.

[0132] Both sides of the sliding frame B41 are fixedly provided with first guide bars B411, and the two first guide bars B411 extend into the guide grooves of the guide wheel B6 respectively.

[0133] Both ends of the sliding frame B41 are equipped with limit bars B412 (to prevent the guide wheel B6 from sliding out of the sliding frame B41).

[0134] It is worth noting that the guide wheel B6 is installed on both sides of the discharge port B11 via the mounting plate. Through the cooperation between the guide wheel B6 and the guide bar, the sliding frame B41 can be slidably installed at the bottom of the transfer hopper B1, thereby allowing the discharge port B11 to be opened and closed.

[0135] The sliding structure of the sliding frame B41 in this technical solution, in conjunction with the guide wheel B6, has less friction compared to the sliding groove structure, allowing the sliding frame B41 to be moved with less force.

[0136] Further explanation: the fabric unit A3 also includes several first adjustment mechanisms A391 and several second adjustment mechanisms A392. The two sides of the discharge belt A32 can be adjusted and installed on both sides of the frame A1 through the first adjustment mechanisms A391.

[0137] The first adjustment mechanism A391 includes a first adjustment screw and a first locking member. One end of the first adjustment screw is fixedly installed on the frame A1, and the other end of the first adjustment screw is connected to the discharge belt A32. The first adjustment screw is set vertically, and the first adjustment mechanism A391 is used to adjust the installation height of the discharge belt A32.

[0138] The two sides of the collecting belt A33 are adjustablely mounted on both sides of the frame A1 via the second adjusting mechanism A392, and the collecting belt A33 is located below the discharge belt A32. The second adjusting mechanism A392 is used to adjust the installation height of the collecting belt A33.

[0139] The second adjustment mechanism A392 includes a second adjustment screw and a second locking member. One end of the second adjustment screw is fixedly installed on the frame A1. The two sides of the collecting belt A33 are respectively provided with connecting parts that cooperate with the second adjustment screw. The other end of the second adjustment screw is connected to the connecting part of the collecting belt A33. The collecting belt A33 can move up and down along the height direction of the second adjustment screw. The second locking member is used to fix the connecting part.

[0140] It is worth noting that this technical solution uses a discharge belt A32 to transport the color material to a collection belt A33. The collection belt A33, through its cyclical rotation, stacks and mixes several color materials, then conveys the preliminarily mixed powder to a collection hopper A34 for further mixing. To ensure that the color material in the discharge belt A32 falls completely into the collection belt A33, the alignment height between the discharge belt A32 and the collection belt A33 needs to be controlled. If the gap between the discharge belt A32 and the collection belt A33 is too large, the color material in the discharge belt A32 may splash to other places during the fall, resulting in waste and affecting equipment operation. If the gap between the discharge belt A32 and the collection belt A33 is too small, it will hinder the powder from falling from the discharge belt A32 to the collection belt A33, potentially causing operational difficulties for both belts. Therefore, controlling the alignment height between the discharge belt A32 and the collection belt A33 is crucial. This technical solution sets up a first adjustment mechanism A391, which includes a first adjustment screw and a first locking member. The discharge belt A32 can move along the height direction of the first adjustment screw, thereby adjusting the installation height of the discharge belt A32. After the height of the discharge belt A32 is adjusted, the position of the discharge belt A32 is fixed by the first locking member, thereby fixing the discharge belt A32 on the frame A1.

[0141] Preferably, the first locking element is a locking nut.

[0142] In this technical solution, the installation height of the collecting belt A33 is adjustable through the second adjustment mechanism A392, which allows for better adjustment of the matching position between the discharge belt A32 and the collecting belt A33, as well as the matching position between the collecting belt A33 and the collecting hopper A34, thereby ensuring that all the mixed powder from the collecting belt A33 falls into the collecting hopper A34.

[0143] Specifically, in this technical solution, the collecting belt A33 can move up and down along the height direction of the second adjusting screw. After the height of the collecting belt A33 is adjusted, the position of the collecting belt A33 is fixed by the second locking component, thereby fixing the collecting belt A33 onto the frame A1. In this technical solution, the second locking component is a locking nut.

[0144] This technical solution also includes a third adjusting mechanism A393, through which the feeding hopper A31 is installed vertically and adjustablely above the discharge belt A32. The installation scheme and adjustment principle of the third adjusting mechanism A393 are the same as those of the first adjusting mechanism A391.

[0145] This technical solution allows for the adjustment of the installation height of the discharge belt A32 via the first adjustment mechanism A391, the adjustment of the installation height of the collecting belt A33 via the second adjustment mechanism A392, and the adjustment of the installation height of the cloth hopper A31 via the third adjustment mechanism A393. This allows for the adjustment of the coordination interval between the cloth hopper A31, the discharge belt A32, and the collecting belt A33, ensuring that the colored material can be properly conveyed to the next stage.

[0146] Preferably, each fabric unit A3 is provided with three fabric hoppers A31 and three discharge belts A32. The discharge ports of the three fabric hoppers A31 are respectively located above the three discharge belts A32, and the positions of the discharge ports of the three fabric hoppers A31 and the three discharge belts A32 are respectively corresponding.

[0147] The receiving hoppers B511 of the three discharge belts A32 correspond to the receiving positions of the collecting belt A33, so that the three colors of material are stacked on the collecting belt A33.

[0148] When fabric unit A3 is in operation, viewed from the left, the collecting belt A33 rotates counterclockwise from right to left. At this time, the discharge belt A32, located at the front end of the conveying direction of the collecting belt A33, rotates counterclockwise from right to left, causing color material a in the discharge belt A32 to fall onto the collecting belt A33. Then, the discharge belt A32 in the middle rotates clockwise from left to right, causing color material b in the middle discharge belt A32 to fall onto the collecting belt A33, and color material b is stacked on top of color material a. Then, the discharge belt A32 at the end of the conveying direction of the collecting belt A33 rotates clockwise from left to right, causing color material c in the discharge belt A32 to fall onto the collecting belt A33, and color material c is stacked on top of single color material b. This causes the three single color powders to be stacked and mixed together, forming a more colorful mixed powder.

[0149] To further clarify, the discharge belt A32, the collection belt A33, and the briquetting belt A36 are all belt conveyors.

[0150] It is worth noting that in this technical solution, the discharge belt A32, the collection belt A33, and the briquetting belt A36 are all driven by motors.

[0151] Further explanation: The chain drive device B7 includes a transmission chain assembly B71 and a load-bearing wheel assembly B72; the transmission chain assembly B71 includes a transmission chain bracket B711, a transmission motor B713 and a transmission chain B712, with the transmission chain B712 mounted on the transmission chain bracket B711; the transmission motor B713 is drivenly connected to the transmission chain B712.

[0152] The transfer hopper B1 is provided with a fixed seat B12 on the outside, and the fixed seat B12 is fixedly installed with the transmission chain B712;

[0153] The bearing wheel assembly B72 includes a plurality of bearing wheels B721 and a bearing track B722 parallel to the transmission chain bracket B711; the plurality of bearing wheels B721 are mounted on the side of the fixed base B12 away from the transmission chain B712, and the bearing wheels B721 roll along the bearing track B722.

[0154] The transfer hopper B1 also includes a guide assembly B13, which includes a longitudinal guide wheel B131 and a transverse guide wheel B132. The longitudinal guide wheel B131 is mounted on the fixed base B12 by a bracket. The shaft of the longitudinal guide wheel B131 is vertically arranged, and the wheel surface of the longitudinal guide wheel B131 is in contact with the side wall of the transmission chain bracket B711.

[0155] The transverse guide wheel B132 is mounted on the fixed base B12 by a mounting component, and the transverse guide wheel B132 is located below the bearing wheel B721. The shaft of the transverse guide wheel B132 is arranged transversely. The bottom end of the bearing rail B722 is provided with a second guide bar B7221, which is arranged along the extension direction of the bearing rail B722. The wheel surface of the transverse guide wheel B132 and the second guide bar B7221 cooperate with each other.

[0156] Specifically, the transmission chain assembly B71 and the bearing wheel assembly B72 constitute the chain drive device B7, which drives the transfer hopper B1 to move. Since the transfer hopper B1 in this technical solution needs to reciprocate, this technical solution uses a mature and reliable chain drive, which makes it easy to control the distance the device moves and the position where it stops.

[0157] Specifically, in this technical solution, the drive motor B713 is an electric motor, which is connected to the drive chain B712. The motor drives the drive chain B712 to move, thereby moving the transfer hopper B1.

[0158] The guide component B13 of this technical solution is equipped with longitudinal guide wheel B131 and transverse guide wheel B132, which constrain the degrees of freedom of the transfer hopper B1 in the transverse and longitudinal directions, ensuring the reliability of the travel position of the hopper 1. At the same time, through the cooperation of longitudinal guide wheel B131, transverse guide wheel B132, bearing wheel assembly B72 and transmission chain B712, the transfer hopper B1 is slidably installed on the mounting frame B5.

[0159] Preferably, the feeding device B also includes a track brush B8, which is mounted on the mounting base of the bearing wheel B721 and is attached to the upper surface of the bearing track B722.

[0160] In this technical solution, the mounting base of the track brush B8 and the bearing wheel B721 are fixedly connected. When the bearing wheel B721 moves, it can drive the track brush B8 to move, so that the track brush B8 can clean the upper surface of the bearing track B722, sweep away the material that has spilled onto the bearing track B722, and prevent the material spilled onto the bearing track B722 from affecting the movement of the bearing wheel B721. This makes the movement of the transfer hopper B1 smoother and more efficient.
