In the description of the present invention, unless otherwise specified, "multiple" means more than two.

[0048] like Figure 1-8 , a powder material distributing machine for artificial stone slabs, comprising: a wide-grain filler device 1, a powder material storage device 2, a powder material distributing machine frame 3 and a wide-grain filler moving device 4;

[0049] The wide-grain filler device 1 and the powder storage device 2 are respectively installed on the powder distribution frame 3; the output end of the wide-grain filler moving device 4 is connected to the powder distribution frame 3, and is used to drive the powder distribution frame 3 to move at multiple angles;

[0050] The wide-grain filling device 1 comprises: a wide-grain fabric hopper 11, a wide-grain fabric frame 12 and a wide-grain rotating driver 13;

[0051] The wide-grain fabric hopper 11 is provided with a wide-grain material feeding channel 111; the wide-grain fabric frame 12 is provided with a long-width fabric opening 121, the input end of the long-width fabric opening 121 is connected to the output end below the wide-grain material feeding channel 111; the length-width ratio of the long-width fabric opening 121 is greater than 1;

[0052] The wide-grain rotation driver 13 is used to drive the wide-grain fabric frame 12 to rotate and adjust the length direction 1211 and the width direction 1212 of the long-width fabric opening 121 .

[0053] The powder material storage device 2 comprises: a material storage conveying device 22 and a weighing device 24;

[0054] The stock conveying device 22 is installed at the weighing end of the weighing device 24 ; the conveying end of the stock conveying device 22 outputs powder to the wide-grain cloth hopper 11 .

[0055] The present invention provides a powder feeding machine for artificial stone slabs, wherein the wide-grain filling device 1 is provided with a length-width feeding port 121 with a length-width ratio greater than 1, which can control the width of the filling texture, thereby improving the filling efficiency of the wide and narrow textures to reduce costs, and can make the slab form a three-dimensional, natural, unique and beautiful texture, thereby solving the problem that the texture of the existing artificial stone slabs lacks three-dimensionality and naturalness, as well as the problem of low filling efficiency.

[0056] Specifically, the weighing device 24 weighs and records the weights of the storage hopper 21, the storage conveying device 22, the storage breaking mechanism 23, etc. in advance, and can be de-tareed. After the powder is input into the storage hopper 21, the weighing device 24 can weigh the weight of the powder; when the powder is output from the storage conveying device 22 to the wide-weave cloth hopper 11, the total weight detected by the weighing device 24 decreases, and the reduced difference can be the weight of the powder actually output to the wide-weave cloth hopper 11. Based on the uniform speed feeding of the powder by the storage conveying device 22, this solution not only realizes the accurate measurement of the powder discharge amount, but also can prompt to replenish the powder when the total weight is the lowest to ensure sufficient powder. The wide-grain cloth hopper 11 is provided with a wide-grain feeding channel 111, which is equivalent to a funnel structure. The inner diameter of the wide-grain feeding channel 111 gradually narrows from top to bottom, that is, the wide-grain feeding channel 111 forms a large-diameter end at the upper end and a small-diameter end at the lower end; the large-diameter end is more convenient for receiving materials from above, and the small-diameter end can output the powder to the length-width cloth opening 121 of the wide-grain cloth frame 12; the length-width cloth opening 121 has a certain length-width ratio, and the length-width ratio is greater than 1, that is, the length will be larger than the width; after the length-width cloth opening 121 receives the powder, the powder will be distributed according to the inner diameter contour of the length-width cloth opening 121, thereby distributing the powder according to the length and width of the length-width cloth opening 121. The output end of the wide-grain rotation driver 13 is directly or indirectly connected to the wide-grain fabric frame 12, and is used to drive the wide-grain fabric frame 12 to rotate, drive the long-width fabric opening 121 to rotate, and can adjust the length direction 1211 and the width direction 1212 of the long-width fabric opening 121; when the wide-grain fabric frame 12 is spreading powder to a certain area, the side of the wide-grain fabric frame 12 in the length direction 1211 is perpendicular to the fabric direction, and the width of the fabric is large; when the side of the wide-grain fabric frame 12 in the width direction 1212 is perpendicular to the fabric direction, the width of the fabric is small. Furthermore, the length direction 1211 or the width direction 1212 can be tilted toward the fabric direction, so that the width of the fabric is smaller than the length or width of the long-width fabric opening 121. When the patterned fabric frame 12 is projected onto the fabric area in the length direction 1211 or the width direction 1212, the width of the filler texture can be controlled. The width can concentrate the fabric in a certain area to avoid powder waste, thereby improving the filling efficiency of wide and narrow textures.

[0057] The powder in this solution can be conventional artificial stone powder, colorant, or other powder for enhancing texture effect. That is, this solution can output artificial stone powder, colorant, or other powder for enhancing texture effect to the slab using the long and wide feeding port 121.

[0058] The wide-grip rotation driver 13 is a well-known mechanism with a driving rotation function, such as a motor, or a combination of a motor and a reducer.

[0059] In one embodiment, the wide-grain fabric frame 12 is rotatably mounted on the lower end of the wide-grain fabric hopper 11, and the output end of the wide-grain rotation driver 13 is connected to the wide-grain fabric frame 12, so as to drive the wide-grain fabric frame 12 to rotate relative to the wide-grain fabric hopper 11.

In this embodiment, the position of the wide-grain fabric hopper 11 can be rotated and adjusted, for example, it is rotatably installed on the wide-grain filling frame 14; the wide-grain fabric frame 12 is integrally connected to the wide-grain fabric hopper 11; it is only necessary to connect the output end of the wide-grain rotation driver 13 to the wide-grain fabric frame 12 or the wide-grain fabric hopper 11, so as to drive the wide-grain fabric hopper 11 to rotate relative to the wide-grain filling frame 14, thereby improving the mixing effect, and also rotating the length and width fabric opening 121, thereby adjusting the length direction 1211 and the width direction 1212 of the length and width fabric opening 121.

[0061] The wide-groove rotation driver 13 comprises: a wide-groove rotation motor 131, a wide-groove rotation driving wheel 132 and a wide-groove rotation driven wheel 133;

The wide-grain rotating driving wheel 132 directly drives the wide-grain rotating driven wheel 133 to rotate, driving the wide-grain fabric frame 12 to rotate. In one embodiment, the wide-grain rotating driving wheel 132 and the wide-grain rotating driven wheel 133 are respectively gears, and the two are meshed with the same toothed chain. The wide-grain rotating driving wheel 132 can drive the wide-grain rotating driven wheel 133 to rotate through the toothed chain, driving the wide-grain fabric frame 12 to rotate. In one embodiment, the wide-grain rotating driving wheel 132 and the wide-grain rotating driven wheel 133 are ordinary wheel structures, and a synchronous belt is used to connect the two to rotate synchronously. The wide-grain rotating driving wheel 132 can drive the wide-grain rotating driven wheel 133 to rotate through the toothed chain, driving the wide-grain fabric frame 12 to rotate.

[0064] Optimally, the wide-grain filler device 1 further comprises: a wide-grain filler frame 14 and a tamping device 15;

[0065] The wide-grain cloth hopper 11, the wide-grain rotation driver 13 and the pounding device 15 are respectively installed on the wide-grain filler frame 14;

[0066] The output end of the pounding device 15 extends into the wide-grain feed channel 111 .

[0067] The wide-grain filler frame 14 is a frame of the wide-grain cloth hopper 11, the wide-grain cloth frame 12, the wide-grain rotation driver 13 and the pounding device 15; the output end of the pounding device 15 can extend from top to bottom into the wide-grain feed channel 111, and can crush the powder in the wide-grain feed channel 111 and / or the powder in the long and wide cloth opening 121, thereby breaking the block material and preventing the block stone from blocking the wide-grain feed channel 111 and / or the long and wide cloth opening 121.

[0068] The tamping device 15 comprises: a tamping lifting driver 151 and a tamping device 152;

[0069] The output end of the pounding material lifting driver 151 is connected to the pounding device 152 for driving the pounding device 152 to move up and down, so that the pounding device 152 is lifted and lowered in the wide-grain feeding channel 111 and / or the long and wide material distributing port 121 .

[0070] The pounding lifting driver 151 can be used to drive the pounder 152 to lift and move, so that the pounder 152 is lifted and lowered in the wide-grain feed channel 111 and / or the long and wide material distribution port 121, and the powder in the wide-grain feed channel 111 and / or the long and wide material distribution port 121 can be crushed, mainly by crushing the block powder through the lifting action of the pounder 152.

[0071] The pounding lifting driver 151 is a well-known mechanism with a driving lifting function, such as a pneumatic cylinder, an oil cylinder, a combination of a motor and a screw rod, a mechanical arm, etc.

[0072] The pounding device 15 further includes: a pounding rotation driver 153;

[0073] The pounding material rotating driver 153 is installed on the wide-grain filler frame 14 , and the output end of the pounding material rotating driver 153 is connected to the pounding material lifting driver 151 , so as to drive the pounding material lifting driver 151 to rotate, thereby driving the pounding device 152 to rotate.

[0074] The pounding rotating driver 153 can drive the pounding lifting driver 151 to rotate, thereby driving the pounder 152 of the pounding lifting driver 151 to rotate. In addition to crushing the powder by lifting, the pounder 152 can also crush the powder by rotating to prevent clogging of the material hopper and make material discharge smoother.

[0075] The tamping rotation driver 153 is a well-known mechanism with a driving rotation function, such as a motor, or a combination of a motor and a reducer.

[0076] The tamping device 152 includes a tamping fixing plate 1521 and a tamping column 1522;

[0077] The plurality of pounding columns 1522 are installed in a straight line on the same pounding fixed plate 1521, and a gap is formed between two adjacent pounding columns 1522; the output end of the pounding lifting driver 151 is connected to the pounding fixed plate 1521, and is used to drive the pounding fixed plate 1521 to move up and down, so that the plurality of pounding columns 1522 can be moved up and down.

The pounding lifting driver 151 drives the pounding fixed plate 1521 to rise and fall, and can drive a plurality of pounding columns 1522 to rise and fall simultaneously; the bottom surface area of ​​the lower end of the pounding column 1522 is small, and the contact area with the powder is small, so the pressure when the pounding column 1522 presses down is strong, and the powder can be crushed more easily. Combined with the rotation driving action of the pounding rotating driver 153 on the pounding lifting driver 151, the pounding column 1522 can also rotate after crushing the powder, and the powder is free in the gap between the pounding columns 1522 after being crushed, and the powder is crushed more evenly. At the same time, the pounding column 1522 can rotate synchronously with the wide-grain cloth hopper 11 while crushing the powder mass, and the powder is free in the gap between the pounding columns 1522 after being crushed and filled into the texture groove.

[0079] Optimally, the powder material storage device 2 further includes: a storage hopper 21 and a material storage scattering mechanism 23;

[0080] The material storage hopper 21 is installed on the material storage conveying device 22; the material storage breaking mechanism 23 is installed on the material storage conveying device 22 and is located at the end of the conveying end;

[0081] The material storage hopper 21 is provided with a material storage inner cavity 211, and one side of the material storage hopper 21 is provided with a material storage outlet 212 that exposes the material storage inner cavity 211, and the material storage outlet 212 is located above the conveying end of the material storage conveying device 22; the material storage hopper 21 is also provided with a material storage baffle 213 that blocks the material storage outlet 212, and the material storage baffle 213 is movably adjusted to the material storage outlet 212 to control the exposure size of the material storage outlet 212.

[0082] Specifically, the storage hopper 21 is used to store powder, and the powder is stored in the storage inner cavity 211; the powder in the storage inner cavity 211 can be output to the outside of the storage hopper 21 through the storage outlet 212 on the side; and the storage outlet 212 is located above the conveying end of the storage conveying device 22, so when the storage outlet 212 is exposed, the powder can be output to the conveying end of the storage conveying device 22 through the storage outlet 212; the conveying end of the storage conveying device 22 drives the powder to pass through the last position, and the powder is broken up by the storage breaking mechanism 23, so that the powder is dispersed and output to the outside. The material storage hopper 21 and material storage dispersing mechanism 23 of the present scheme are respectively installed on the material storage conveying device 22, and the material storage conveying device 22 is installed at the weighing end of the weighing device 24. Therefore, the weighing device 24 is equivalent to weighing the material storage hopper 21, the material storage conveying device 22 and the material storage dispersing mechanism 23 and the powder attached thereto. The weight of the powder will change only when it is completely separated from the powder storage device 2, and the powder remaining in the material storage hopper 21, the material storage conveying device 22 or the material storage dispersing mechanism 23 will not be calculated; in the initial state, the weighing device 24 weighs and records the weights of the material storage hopper 21, the material storage conveying device 22 and the material storage dispersing mechanism 23 in advance, and the weights can be peeled off. After the powder is input into the material storage hopper 21, the weighing device 24 can weigh the weight of the powder; when the powder is output from the material storage conveying device 22 to the outside, the total weight detected by the weighing device 24 decreases, and the difference in the decrease is the actual output weight of the powder. At the same time, the present solution can also control the amount of powder output to the output end of the material storage conveying device 22 by adjusting the material storage baffle 213 on one side of the material storage hopper 21. The material storage baffle 213 can be adjusted to completely block the material storage outlet 212, or completely expose the material storage outlet 212, or half-cover the material storage outlet 212.

[0083] The material storage baffle 213 is installed on the material storage hopper 21 through the material storage screw 214;

[0084] The material storage baffle 213 is provided with a material storage adjusting groove 2131 extending in a straight line, and the material storage screw 214 passes through the material storage adjusting groove 2131 and is installed in the material storage screw hole of the material storage hopper 21 . The material storage baffle 213 is movable and adjustable along the length direction 1211 of the material storage adjusting groove 2131 .

[0085] The material storage baffle 213 is fixed to the material storage screw hole of the material storage hopper 21 by means of the material storage screw 214, and the material storage screw 214 can be tightened and adjusted as needed; when the material storage screw 214 is not tightened, the material storage baffle 213 can be movably adjusted along the length direction 1211 of the material storage adjustment groove 2131, so that the material storage screw hole is relatively moved to the two ends of the material storage adjustment groove 2131, thereby adjusting the position of the material storage baffle 213; when the position adjustment of the material storage baffle 213 is completed, the material storage baffle 213 can be tightened, and the screw head of the material storage screw 214 presses the material storage baffle 213 against the side of the material storage hopper 21, thereby limiting the material storage baffle 213.

[0086] The stock adjustment slot 2131 extends vertically, and the stock baffle 213 can be adjusted vertically to contact or approach the conveying end of the stock conveying device 22. The stock baffle 213 of this solution is preferably adjusted up and down. When the stock baffle 213 contacts or approaches the conveying end of the stock conveying device 22, the exposed area of ​​the stock outlet 212 is the smallest, and the output of the powder is the smallest; at the same time, because the stock baffle 213 is adjusted vertically, when the powder passes horizontally through the stock baffle 213, the stock baffle 213 will scrape the powder flat, so that it can be output at a specific height at the conveying end of the stock conveying device 22, so that the powder is output in blocks, and the stable delivery of the powder is maintained.

[0087] The stock material breaking mechanism 23 comprises: a stock material roller brush 231 and a roller brush driver 232;

[0088] The stock roller brush 231 is installed horizontally on the stock conveying device 22 and is located at the end of the conveying end; the roller brush driver 232 is installed on the stock conveying device 22, and the output end of the roller brush driver 232 is connected to the stock roller brush 231, which is used to drive the stock roller brush 231 to rotate. In this solution, the stock roller brush 231 is used to break up the powder. The roller brush driver 232 can drive the stock roller brush 231 to rotate, and the stock roller brush 231 breaks up the powder through its own brush; the brush is a well-known structure, which is generally hard and can shear the internal structure of the powder when it contacts the powder, thereby breaking up larger agglomerates of color powder, increasing the looseness of the powder, and avoiding uneven discharge.

[0089] The roller brush driver 232 is a well-known mechanism with a driving rotation function, such as a motor, or a combination of a motor and a reducer.

[0090] The material storage outlet 212 is disposed adjacent to the material storage roller brush 231. The material storage outlet 212 can face and be close to the material storage roller brush 231; after the powder is output from the material storage outlet 212, it is directly broken up by the material storage roller brush 231; because the material storage roller brush 231 is disposed at the end of the conveying end of the material storage conveyor 22, the powder can be broken up immediately after being output, and then output to the outside of the powder storage device 2 through the conveying end of the material storage conveyor 22, which shortens the moving distance of the powder, and the output response of the powder is fast, which prevents the powder from scattering outside the conveying end.

[0091] The stock conveying device 22 is a conveyor belt device. The stock conveying device 22 of this solution can be replaced by a well-known mechanism with a conveying function, such as a mobile trolley, a conveying roller device, a mechanical arm, etc., which drives the pollination frame for receiving the powder to move, as long as the powder can be moved horizontally. And this solution preferably uses a conveyor belt device, and the conveyor belt of the conveyor belt device can be directly used as the conveying end, and the powder can be directly placed on the conveyor belt. According to common knowledge, the motor can drive the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the conveyor belt, thereby driving the powder on the conveyor belt to be transported. The advantage of this structure is that the powder does not need to be moved by the pollination frame, and the powder can be directly placed on the conveyor belt.

[0092] Optimally, the powder material storage device 2 further includes: a material storage and guide shell 25;

[0093] The material storage guide housing 25 is installed on the material storage conveying device 22; the material storage guide housing 25 is provided with a material storage guide groove 251, and the material storage guide groove 251 is inclined downward to below the conveying end of the material storage conveying device 22;

[0094] The material storage hopper 21, material storage conveying device 22, material storage breaking mechanism 23, weighing device 24 and material storage guiding shell 25 form a material distribution unit 20; there are multiple material distribution units 20, and the material storage guiding shells 25 of multiple material distribution units 20 are oriented toward or extend into the wide-grain material hopper 11.

[0095] The material storage guide shell 25 is also installed on the material storage conveying device 22. For the powder that has not fallen out of the material storage guide shell 25, the weighing device 24 will not calculate the weight of the powder remaining in the material storage guide shell 25; and the material storage guide groove 251 is downwardly inclined below the conveying end of the material storage conveying device 22, and the powder output from the material storage conveying device 22 can fall into the material storage guide groove 251 and be output to the outside under the guidance of the material storage guide groove 251.

[0096] The wide-grain cloth hopper 11 is used to receive powders from multiple cloth units 20. Different cloth units 20 are used to output the same or different powders, and the powders will be mixed in the wide-grain cloth hopper 11. Based on the fact that each cloth unit 20 can achieve accurate measurement of the powder output, this solution can achieve quantitative output of the same or different powders, thereby meeting the accurate measurement of the output of multiple powders.

[0097] It can be optimized to further include: a stone conveying mechanism;

[0098] The conveying end of the stone conveying mechanism is used to receive and convey artificial stone. The stone conveying mechanism is communicatively connected to the wide-grain filler device 1 and the powder storage device 2. The wide-grain filler device 1 is used to distribute powder to the artificial stone conveyed by the stone conveying mechanism.

[0099] The stone conveying mechanism is used for conveying, receiving and conveying artificial stone, and its conveying speed can cooperate with the powder spreading speed of the wide-grain filler device 1 and the discharging speed of the powder storage device 2, so as to form a three-dimensional, natural, unique and beautiful texture of the slab.

[0100] A method for distributing powder of an artificial stone plate, using a powder distributing machine for an artificial stone plate according to any of the above embodiments, comprises the following steps:

[0101] (1) The system presets the texture pattern of the artificial stone, and each texture pattern corresponds to at least one texture path 102;

[0102] The texture path 102 is a shape of a texture pattern from one end to the other end, and the length and width fabric opening 121 moves along the extension direction of the texture path 102;

[0103] (2) The wide-grain fabric frame 12 moves along the grain path 102, and the material storage conveyor 22 outputs the powder to the wide-grain fabric hopper 11, and the wide-grain fabric hopper 11 outputs the powder to the artificial stone through the long and wide fabric opening 121;

[0104] The wide-grained material frame 12 can move along the grain path 102, and the long and wide material openings 121 of the wide-grained material frame 12 output the powder from the material storage conveying device 22, so that the powder fills the artificial stone along the grain path 102;

[0105] The powder in this solution may be powder of conventional artificial stone, or may be colorant, or other powder for enhancing texture effect.

[0106] (3) The weighing device 24 detects the change in the total weight of the powder in the powder storage device, and the storage conveying device 22 conveys the powder at a uniform speed; the wide-grain rotation driver 13 drives the wide-grain cloth frame 12 to rotate around the center according to the grain width and grain path 102 of the grain pattern, and adjusts the length and width cloth opening 121 in the length direction 1211 and the width direction 1212 during the cloth process.

[0107] Since the material storage conveying device 22 is installed at the weighing end of the weighing device 24, when the powder is output to the wide-grain cloth hopper 11 through the material storage conveying device 22, the weight detected by the weighing device 24 decreases. The weight change is the weight of the powder output, which can prompt the replenishment of the powder when the weight is low. Every time the long and wide cloth port 121 passes a certain position on the texture path 102, based on the fact that the feeding speed of the material conveying device 22 is uniform, the residence time of the long and wide cloth port 121 on the texture path 102 can be set to control the output weight of the powder. At the same time, since the wide-grain fabric frame 12 can rotate around its own center, the length and width fabric opening 121 can be adjusted according to the size of the grain width. For example, when the length and width fabric opening 121 moves to the minimum grain width, the width direction 1212 can be directed toward the grain path 102, and the length direction 1211 can be directed toward both sides of the grain path 102. The width direction 1212 can just meet the filling of the texture pattern, and the width of the length and width fabric opening 121 overlaps with the projection of the texture path 102. The length direction 1211 can extend the filling amount of the length and width fabric opening 121 in one moving unit.

[0108] It can be optimized that in the step (1), the system also presets the cloth rectangle 101 according to the length and width of the length and width cloth opening 121, distributes the multiple cloth rectangles 101 at any angle on the texture path 102 according to the principle of continuous arrangement, and records the angle and position of each cloth rectangle 101 as the cloth opening position parameter;

[0109] In the step (3), the length and width cloth opening 121 is moved in sequence according to the cloth opening position parameters and projected onto each cloth rectangle 101 .

[0110] The cloth rectangle 101 is designed according to the length and width of the length and width cloth opening 121, and multiple cloth rectangles 101 will be distributed sequentially and continuously on the texture path 102, so that the texture path 102 is divided into several cloth rectangles 101. Since the texture path 102 may be a curved shape, the angle of each cloth rectangle 101 may be different. The cloth opening position parameter records the angle and position of each cloth rectangle 101. The wide-grain rotation driver 13 can control the length and width cloth opening 121 to rotate to the corresponding angle according to the cloth opening position parameter, and the wide-grain filler moving device 4 can control the length and width cloth opening 121 to move to the corresponding position according to the cloth opening position parameter.

[0111] The powder material of the present solution can be output to the surface of the artificial stone body or the powder material on the surface of the artificial stone as needed, and the specific spatial position can be a concave texture groove or a flat horizontal surface.

[0112] For the embodiment of the texture groove, before performing step (2), a texture groove is pre-opened on the surface of the artificial stone body or on the powder on the surface of the artificial stone body; the system calculates the volume V1 of the artificial stone according to the length a, width b and thickness c of the artificial stone, and then calculates the weight m of the artificial stone according to the density ρ1 of the artificial stone; and then calculates the texture height d required for the powder filling of the texture pattern according to the known density ρ2 of the powder;

[0113]

[0114] In the step (3), after the powder in a certain distribution rectangle 101 is filled to the texture height, the length and width distribution port 121 moves to the next distribution rectangle 101 .

[0115] The outline of the texture groove can be the outer outline of the texture pattern. When the length and width cloth opening 121 fills the powder into the texture groove, the optimal texture height needs to be calculated; since the length and width cloth opening 121 can be adaptively rotated to overlap the projection with the cloth rectangle 101, it is only necessary to ensure that the texture height of the powder filled in each cloth rectangle 101 is consistent or similar, thereby forming a continuous texture pattern. At the same time, after determining the texture height, the height position of the length and width cloth opening 121 can be determined, and the length and width cloth opening 121 can be infinitely close to the surface of the artificial stone. The filled powder can enter the texture groove in a shorter time, and the filling efficiency is improved.

[0116] Optimally, in step (2), the system associates the moving speed of the length and width cloth opening 121 along the texture path 102 with the speed of the stock conveying device 22, and reaches the texture height required for filling according to the residence time of the length and width cloth opening 121 in the cloth rectangle 101.

[0117] After calculating the required texture height d, the system controls the speed of the stock conveying device 22 according to the weight of the material required to be filled in each cloth rectangle 101. Therefore, the system can control the time the long and wide cloth port 121 stays at this position (i.e., the time the cloth is laid at this position) according to the speed of the stock conveying device 22 and the moving speed of the long and wide cloth port 121 along the texture path 102 (i.e., the moving speed on the X-axis and Y-axis of the long and wide cloth port 121), thereby controlling the actual discharge amount of the long and wide cloth port 121 in the cloth rectangle 101, so as to achieve the texture height at this position.

[0118] For example, when the material discharging rate of the storage conveyor 22 is constant, the material discharging demand can be met immediately by only coordinating the length and width discharging port 121 to move at a specific speed, and there is no need to increase the discharging speed of the conveyor belt. When the amount of powder to be filled is large, the material discharging rate of the storage conveyor 22 needs to be increased to increase the feeding amount.
