[0042] As Figures 1-5 , a calendering and forming device for dry-method preparation of ecological stone, comprising: a fabric mechanism 11, a block transfer mechanism 12 and a block compaction mechanism 13;
[0043] The conveying end of the block transfer mechanism 12 is used to receive the powder of the fabric mechanism 11; the fabric mechanism 11 includes: a feeder 111 and a fabric block roller 112;
[0044] The roll surface of the cloth forming roll 112 is provided with a forming roll groove 1120; the cloth forming roll 112 is rotatably arranged at the output end of the cloth feeder 111, and the roll surface of the cloth forming roll 112 abuts against other contact surfaces;
[0045] The forming and compacting mechanism 13 includes: a first forming press roll 131 and a forming guide plate 132;
[0046] The forming guide plate 132 and the first forming press roll 131 are sequentially distributed along the conveying direction of the forming conveying mechanism 12; the first forming press roll 131 and the conveying end of the forming conveying mechanism 12 form a squeezing gap 1311; the forming guide plate 132 is located on both sides of the forming conveying mechanism 12 in the conveying direction, and a necking 130 is formed between the forming guide plates 132 on both sides; the caliber of the necking 130 gradually decreases along the conveying direction of the forming conveying mechanism 12.
[0047] This solution provides a calendering and forming device for dry-prepared ecological stone, which uses the forming roll groove 1120 of the cloth forming roll 112 to output the dry powder in blocks and transfers it to the forming conveying mechanism 12 to press the powder through the forming guide plates 132 on both sides, so as to achieve the calendering effect of ecological stone by dry process, and solve the problems of non-fusion of colors, unnatural transition, and no casting texture effect in the dry forming of ecological stone.
[0048] Specifically, the distributor 111 contains the dry powder of ecological stone, which is the inorganic raw material of the well-known ecological stone; when the distributor 111 outputs, the dry powder of the distributor 111 needs to pass through the block-forming roller 112; the block-forming roller 112 is rotatably arranged at the output end of the distributor 111, and the roller surface of the block-forming roller 112 abuts against other contact surfaces, that is, the block-forming roller 112 can be the inner wall of the distributor 111, other plate structures or another block-forming roller 112, etc., and the inner wall of the distributor 111, other plate structures or another block-forming roller 112, etc. can all provide contact surfaces to abut against the roller surface of the block-forming roller 112; for example, in one of the embodiments, the number of the block-forming rollers 112 can be single, and the single one mainly contacts the inner wall of the distributor 111; for example, in one of the embodiments, the roller surfaces of two adjacent block-forming rollers 112 are adjacent to each other, and the roller surfaces receive the dry powder by using the block-forming roller grooves 1120 under the rotation action, and the dry powder is accommodated in the block-forming roller grooves 1120, and then the block-forming roller grooves 1120 rotate and are adjacent to the roller surface of another block-forming roller 112; thus, other contact surfaces provided by the inner wall of the distributor 111, other plate structures or another block-forming roller 112, etc. squeeze the dry powder into the block-forming roller grooves 1120, so that the dry powder can be formed into blocks along the block-forming roller grooves 1120; when the block-forming roller grooves 1120 continue to rotate until the notch is downward, the block-shaped powder in the block-forming roller grooves 1120 will fall under the action of gravity, so as to separate from the block-forming roller 112, and the dry powder is output from the distributor 111 in a block form; among them, the block-shaped powder can be directly output to the conveying end of the block-forming conveying mechanism 12, or can be indirectly output to the conveying end of the block-forming conveying mechanism 12 after passing through other conveying mechanisms (such as the receiving conveying mechanism 113 or the block-receiving conveyor device 115) first. In short, the block-shaped powder output from the distributor 111 is finally output to the conveying end of the block-forming conveying mechanism 12; the block-forming guide plate 132 and the first block-forming pressing roller 131 are sequentially distributed at the conveying end of the block-forming conveying mechanism 12; the first block-forming pressing roller 131 and the conveying end of the block-forming conveying mechanism 12 form a pressing gap 1311, and the block-shaped powder first passes through the pressing gap 1311 of the first block-forming pressing roller 131. Under the relative rotation action of the first block-forming pressing roller 131, multiple block-shaped powders are further rolled into a larger and continuous block structure; the block-shaped powder then enters the constriction 130 formed by the block-forming guide plate 132, and the diameter of the constriction 130 gradually decreases in the conveying direction of the block-forming conveying mechanism 12, so that the block-shaped powder is subjected to the squeezing force from the outside to the inside, and thus a calendering structure is further extruded on the surface of the block-shaped powder, such as Figure 7; Subsequently, it can enter the extrusion gap 1311 of the second forming roller 133 as needed; the second forming roller 133 can re-roll the bulk powder material, thereby forming a calendering structure for the second time; the bulk powder material can form a natural stone texture with a calendering effect, so as to achieve the calendering effect of ecological stone by a dry process, and solve the problems of non-fusion of colors, unnatural transition, and no casting texture effect in the dry forming of ecological stone.
[0049] The cloth forming roller 112, the first forming press roller 131, and the second forming roller 133 can be rotated through a mechanism known to have driving rotation, such as being driven by a motor, or a combination of a motor and a speed reducer, etc.
[0050] The forming conveying mechanism 12 is a mechanism known to have a conveying function, such as a conveyor belt device, a moving trolley, or a combination formed by a conveying roller device and a die frame for receiving powder materials, etc.
[0051] Optimally, the roller surfaces of two adjacent cloth forming rollers 112 are adjacent to each other, and / or the roller surface of one of the cloth forming rollers 112 contacts the inner wall of the cloth feeder 111.
[0052] Such as Figure 3 , in this solution, it is preferably to use two cloth forming rollers 112 to press the powder material. The cloth forming rollers 112 can rotate in opposite directions to form bulk powder material at the forming roller groove 1120 between the two cloth forming rollers 112; at the same time, such as Figure 6 , in this solution, it is also possible to make the roller surface of the cloth forming roller 112 contact the inner wall of the cloth feeder 111, and the inner wall of the cloth feeder 111 presses the powder material onto the forming roller groove 1120, thereby forming bulk powder material.
[0053] Optimally, the cloth feeding mechanism 11 further includes: a material receiving conveying mechanism 113 and a collecting hopper 114;
[0054] The conveying end of the material receiving conveying mechanism 113 moves past the lower part of the output end of the cloth feeder 111 and also moves past the upper part of the input end of the collecting hopper 114; the conveying end of the forming conveying mechanism 12 passes by the lower part of the output end of the collecting hopper 114.
[0055] After adding powder materials from the cloth feeder 111, they are mixed in the cloth feeder 111 and then output to the material receiving conveying mechanism 113; after the material receiving conveying mechanism 113 receives the bulk powder material from the cloth feeder 111, it conveys it in the direction of the input end of the collecting hopper 114; after the collecting hopper 114 receives the bulk powder material, it conveys the bulk powder material to the forming and compacting mechanism 13 in the direction of the conveying end of the forming conveying mechanism 12.
[0056] Optimally, the number of the cloth feeders 111 is multiple and they are arranged along the conveying direction of the material receiving conveying mechanism 113.
[0057] There can be multiple distributors 111, and different ecological stone raw materials can be added to different distributors 111, and inorganic raw materials, colorants, additives, etc. can be added as needed; the multiple distributors 111 output bulk powder materials to the conveying end of the material receiving and conveying mechanism 113, and then output them to the aggregate hopper 114 in sequence; the aggregate hopper 114 then outputs the bulk powder materials to the conveying end of the forming conveying mechanism 12. Thus, different distributors 111 can form different bulk powder materials, and the differences formed after the combination of different bulk powder materials can make the texture structure more complex, thereby making the calendering effect better.
[0058] Optimally, the distributing mechanism 11 further includes: a block connecting conveyor device 115;
[0059] The block connecting conveyor device 115 is arranged between the upper and lower positions of the distributing and forming roller 112 and the material receiving and conveying mechanism 113; the conveying end of the block connecting conveyor device 115 passes below the distributing and forming roller 112, and the conveying end of the material receiving and conveying mechanism 113 horizontally passes below the conveying end of the block connecting conveyor device 115.
[0060] The block connecting conveyor device 115 is a conveyor device, which is arranged below the distributing and forming roller 112 and above the material receiving and conveying mechanism 113. The conveyor belt of the block connecting conveyor device 115 can provide a large receiving surface as the conveying end, can receive the bulk powder materials output from the distributing and forming roller 112, and outputs them to the output end of the material receiving and conveying mechanism 113 under the action of gravity at the conveying end of the block connecting conveyor device 115, and then is output to the aggregate hopper 114 by the conveying end of the material receiving and conveying mechanism 113.
[0061] Optimally, there are multiple closing openings 130.
[0062] That is, there are multiple closing openings 130. The multiple forming guide plates 132 are arranged along the conveying direction of the forming conveying mechanism 12. For example, there are multiple closing openings 130 between the first forming pressing roller 131 and the second forming roller 133. The multiple closing openings 130 can enable the bulk powder materials to be subjected to multiple squeezes from the outside to the inside on both sides in the conveying direction. After being squeezed, the bulk powder materials form a calendering effect in the middle, and the multiple closing openings 130 can make the texture more complex and can further extend it, improving the calendering effect.
[0063] Optimally, the forming and compacting mechanism 13 further includes: a calendering powder supplementing device 134;
[0064] The output end of the calendering powder supplementing device 134 is located at the conveying end of the forming conveying mechanism, specifically between the closing opening 130 and the second forming roller 133, and the calendering powder supplementing device 134 is used for outputting dry powder.
[0065] The calendering powder replenishing device 134 can replenish dry powder to the bulk powder between the necking 130 and the second forming roller 133, enabling the dry powder to be output to the surface of the bulk powder. Since the bulk powder has been formed with patterns, the dry powder can be replenished into the cracks formed after extrusion or added along the patterns, thereby making the patterns more three-dimensional and obvious. Also, the thickness of the bulk powder can be controlled at the extrusion gap 1311. Thus, the bulk powder after powder replenishment passes through the extrusion gap 1311 of the second forming roller 133, and the second forming roller 133 presses the bulk powder after powder replenishment downward, making the bulk powder firmer and the calendering effect not easily dispersed.
[0066] The forming and compressing mechanism 13 further includes: a second forming roller 133;
[0067] The first forming roller 131, the forming guide plate 132, and the second forming roller 133 are sequentially distributed along the conveying direction of the forming conveying mechanism 12; the second forming roller 133 forms an extrusion gap 1311 with the conveying end of the forming conveying mechanism 12. The second forming roller 133 can perform secondary rolling on the bulk powder, thereby forming a calendering structure twice and further enhancing the calendering effect.
[0068] Optimally, it further includes: a turning mechanism 15 and an unloading conveying mechanism 14;
[0069] The turning mechanism 15 includes: a turning conveying device 151 and a turning roller 152;
[0070] The conveying end of the turning conveying device 151 horizontally passes below the conveying end of the forming conveying mechanism 12; the turning roller 152 is located above the conveying end of the turning conveying device 151 and forms a turning pressing gap; the conveying end of the unloading conveying mechanism 14 is provided with a receiving mold, and the unloading conveying mechanism 14 drives the receiving mold to move past below the conveying end of the turning conveying device 151.
[0071] This solution can turn the bulk powder once after the calendering and forming of the bulk powder. Specifically, after the bulk powder passes through the forming and compressing mechanism, it will fall from the conveying end of the forming conveying mechanism 12 to the turning conveying device 151 under the action of gravity, and the bulk powder is turned during the falling process. Just like when the forming conveying mechanism 12 is a conveyor belt device, the bulk powder can be flipped by nearly 90° after being output from the conveying end of the forming conveying mechanism 12. The turned bulk powder will first pass through the turning roller 152. When the bulk powder passes through the turning pressing gap below the turning roller 152, the turning roller 152 and the conveying end of the turning conveying device 151 jointly press the bulk powder, and the turning roller 152 rolls the bulk powder once again, enabling the different-color powders to produce a fused and transitional extended texture, thereby further improving the calendering effect of the powder.
[0072] Optimally, it further includes: a discharging conveyor mechanism 14;
[0073] The conveying end of the discharging conveyor mechanism 14 passes below the conveying end of the turning conveyor device 151;
[0074] The block compaction mechanism 13 further includes: a cloth-tooth plate 135;
[0075] The cloth-tooth plate 135 is arranged at the conveying end of the turning conveyor device 151.
[0076] The edge of the cloth-tooth plate 135 is provided with a tooth-shaped structure. When the block-shaped powder passes through the conveying end of the turning conveyor device 151, the block-shaped powder will transfer to the conveying end of the discharging conveyor mechanism 14 under the action of gravity; and the cloth-tooth plate 135 arranged at the conveying end of the turning conveyor device 151, when the block-shaped powder is about to fall, the tooth-shaped structure of the cloth-tooth plate 135 can cut the block-shaped powder, so that the turned block-shaped powder is divided into several small pieces and transferred to the receiving mold of the discharging conveyor mechanism 14.
[0077] Optimally, it further includes: a discharging conveyor mechanism 14; the conveying end of the discharging conveyor mechanism 14 passes below the conveying end of the turning conveyor device 151;

[0079] The hollow plate 136 is provided with a hollow opening; the hollow plate 136 is arranged at the conveying end of the turning conveyor device 151.
[0080] The hollow plate 136 is provided with a hollow opening. When the block-shaped powder passes through the conveying end of the turning conveyor device 151, the block-shaped powder will output to the conveying end of the discharging conveyor mechanism 14 through the hollow opening under the action of gravity; the block-shaped powder is positioned at the conveying end of the discharging conveyor mechanism 14 according to the distribution of the hollow openings.
[0081] Optimally, the material receiving conveyor mechanism 113, the block conveying mechanism 12, the discharging conveyor mechanism 14 and / or the turning conveyor device 151 is a conveyor belt device.
[0082] Generally, a conveyor belt device uses a conveyor belt to synchronously connect a driving wheel and a driven wheel, and uses a motor to drive the driving wheel to rotate. Thus, under the synchronous action of the driven wheel, the conveyor belt is driven to rotate, and the linear segment of the conveyor belt moves horizontally to form the conveying end of the material receiving conveyor mechanism 113. The advantage of using a conveyor belt device is that powder can be directly received on the conveyor belt.
