Description

TECHNICAL FIELD

[0001] The present application relates to the field of ecological stone production equipment, and in particular to a calendering forming device and a forming system for preparing ecological stone based on dry method. BACKGROUND

[0002] The existing ecological stone is mainly prepared by wet method. The wet method can keep the powder in a wet state to process surface texture, such as top texture processing and crack processing. In the wet preparation method, a single color or 2-3 color slurries are usually mixed and cast to form decorative texture. However, due to the difficulty in controlling the slurry, the mixing effect of the slurry may be affected, resulting in poor mixing degree of the slurry, and the pattern texture of the ecological stone prepared by the wet method has the problems of poor texture effect and hard texture. At the same time, the powder prepared by the wet method cannot be adjusted in time to form a continuous transition slope when further forming texture because the powder has a certain degree of adhesion between the powder and the powder, which also causes the problem of hard texture in subsequent texture forming.

[0060] As Figures 1-9 A calender molding device for preparing ecological stone based on dry method,

[0061] The calender molding device comprises a distributing mechanism 11, a block conveying mechanism 12 and a block compacting mechanism 13.

[0062] The conveying end of the block conveying mechanism 12 is used for receiving the powder material of the distributing mechanism 11; the distributing mechanism 11 comprises a distributor 111 and a block distributing roller 112.

[0063] The roller surface of the block distributing roller 112 is provided with a block distributing groove 1120; the block distributing roller 112 is rotatably arranged at the output end of the distributor 111, and the roller surface of the block distributing roller 112 abuts against other contact surfaces.

[0064] The block compacting mechanism 13 comprises a first block compacting roller 131 and a block guide plate 132.

[0065] The block guide plate 132 and the first block compacting roller 131 are sequentially arranged along the conveying direction of the block conveying mechanism 12; the first block compacting roller 131 forms an extrusion gap 1311 with the conveying end of the block conveying mechanism 12; the block guide plate 132 is located on both sides of the conveying direction of the block conveying mechanism 12, and the block guide plates 132 on both sides form a converging gap 130 therebetween; the caliber of the converging gap 130 gradually decreases along the conveying direction of the block conveying mechanism 12.

[0066] The scheme provides a calendering forming device for preparing ecological stone based on dry method, which utilizes the lumping roller groove 1120 of the cloth lumping roller 112 to output dry powder in lump, and transfers to the lumping conveying mechanism 12 to press the powder through the lumping guide plates 132 on both sides, so that the calendering effect of ecological stone obtained by dry process can be realized, and the problems of color fusion, unnatural transition and no calendering texture effect in the dry forming of ecological stone are solved.

[0067] Specifically, the distributor 111 is internally provided with dry powder of ecological stone, which is a known inorganic raw material of ecological stone; when the distributor 111 outputs, the dry powder of the distributor 111 needs to pass through the block-distributing roller 112; the block-distributing roller 112 is rotatably arranged at the output end of the distributor 111, and the roller surface of the block-distributing roller 112 is in abutment with other contact surfaces, that is, the block-distributing roller 112 can be in abutment with the inner wall of the distributor 111, other plate structures or another block-distributing roller 112, and the inner wall of the distributor 111, other plate structures or another block-distributing roller 112 can all provide contact surfaces in abutment with the roller surface of the block-distributing roller 112; for example, in one embodiment, the number of block-distributing rollers 112 can be single, and the single block-distributing roller 112 mainly contacts the inner wall of the distributor 111; for example, in one embodiment, the roller surfaces of two adjacent block-distributing rollers 112 are in abutment, and the roller surfaces receive the dry powder under the action of rotation by means of the block-roller groove 1120, the dry powder is contained in the block-roller groove 1120, and the block-roller groove 1120 is further rotated to be in abutment with the roller surface of another block-distributing roller 112; in this way, the other contact surfaces provided by the inner wall of the distributor 111, other plate structures or another block-distributing roller 112 extrude the dry powder into the block-roller groove 1120, so that the dry powder is formed into block-shaped objects along the block-roller groove 1120; when the block-roller groove 1120 continues to rotate to the position where the groove opening is downward, the block-shaped powder in the block-roller groove 1120 falls under the action of gravity, thereby being separated from the block-distributing roller 112, and the dry powder is output from the distributor 111 in the form of block-shaped objects; wherein the block-shaped powder can be directly output to the conveying end of the block-conveying mechanism 12, or can be indirectly output to the conveying end of the block-conveying mechanism 12 after passing through other conveying mechanisms (such as the material-collecting conveying mechanism 113 or the block-receiving conveying belt device 115); in summary, the block-shaped powder output from the distributor 111 is finally output to the conveying end of the block-conveying mechanism 12; the block-conveying guide plate 132 and the first block-pressing roller 131 are sequentially arranged at the conveying end of the block-conveying mechanism 12; the first block-pressing roller 131 forms a pressing gap 1311 with the conveying end of the block-conveying mechanism 12, and the block-shaped powder first passes through the pressing gap 1311 of the first block-pressing roller 131; under the action of relative rotation of the first block-pressing roller 131, the block-shaped powder is further rolled into a block-shaped structure with a larger range and continuity; the block-shaped powder then enters the collecting opening 130 formed by the block-conveying guide plate 132, and the caliber of the collecting opening 130 gradually decreases in the conveying direction of the block-conveying mechanism 12, so that the block-shaped powder is extruded from the outside to the inside, thereby further extruding a calendered structure on the surface of the block-shaped powder, such as Figure 11; the second blocking roller 133 can further roll the blocky powder to form a second rolling structure, so as to form a rolling effect of the imitation natural stone texture, so as to obtain the rolling effect of the ecological stone by the dry process, and solve the problems of color fusion, transition, and no rolling texture effect in the dry forming of the ecological stone.

[0068] The cloth blocking roller 112, the first blocking roller 131 and the second blocking roller 133 can rotate by a known mechanism with a driving rotation function, such as a motor drive, or a combination of a motor and a speed reducer.

[0069] The blocking conveying mechanism 12 is a known mechanism with a conveying function, such as a conveyor belt device, a mobile trolley, or a combination of a conveying roller device and a mold frame receiving powder.

[0070] Optimally, the roller surfaces of two adjacent cloth blocking rollers 112 abut each other, and / or the roller surface of one of the cloth blocking rollers 112 contacts the inner wall of the distributor 111.

[0071] As Figure 4 , the present scheme preferably uses two cloth blocking rollers 112 to press the powder, and the cloth blocking rollers 112 can rotate in opposite directions to form blocky powder at the blocking roller groove 1120 between the two cloth blocking rollers 112; at the same time, as Figure 10 , the present scheme can also make the roller surface of the cloth blocking roller 112 contact the inner wall of the distributor 111, and the inner wall of the distributor 111 presses the powder into the blocking roller groove 1120, thereby forming blocky powder.

[0072] Optimally, the powder distribution mechanism 11 further comprises a material collecting conveying mechanism 113 and a material collecting hopper 114.

[0073] The conveying end of the material collecting conveying mechanism 113 moves below the output end of the distributor 111 and above the input end of the material collecting hopper 114; the conveying end of the blocking conveying mechanism 12 moves below the output end of the material collecting hopper 114.

[0074] After the powder is added to the distributor 111, it is output to the material collecting conveying mechanism 113 after being mixed in the distributor 111; after the material collecting conveying mechanism 113 receives the blocky powder from the distributor 111, it is conveyed to the input end of the material collecting hopper 114; after the material collecting hopper 114 receives the blocky powder, it is conveyed to the conveying end of the blocking conveying mechanism 12, and then the blocky powder is conveyed to the blocking and compacting mechanism 13.

[0075] Optimally, the number of distributors 111 is multiple, and they are arranged along the conveying direction of the material collecting conveying mechanism 113.

[0076] The distributors 111 can be multiple, and different ecological stone raw materials can be added to different distributors 111, and inorganic raw materials, pigments, additives, etc. can be added as needed; multiple distributors 111 output block-shaped powder to the conveying end of the material receiving conveying mechanism 113, and then to the material collecting hopper 114; the material collecting hopper 114 outputs the block-shaped powder to the conveying end of the block conveying mechanism 12. In this way, different distributors 111 can form different block-shaped powders, and the differences between different block-shaped powders can make the texture structure more complex, thereby improving the calendering effect.

[0077] Optimally, the distributing mechanism 11 further comprises a block receiving conveyor belt device 115.

[0078] The block receiving conveyor belt device 115 is arranged between the upper and lower positions of the distributing and blocking roller 112 and the material receiving conveying mechanism 113; the conveying end of the block receiving conveyor belt device 115 passes below the distributing and blocking roller 112, and the conveying end of the material receiving conveying mechanism 113 passes below the conveying end of the block receiving conveyor belt device 115.

[0079] The block receiving conveyor belt device 115 is a conveyor belt device arranged below the distributing and blocking roller 112 and above the material receiving conveying mechanism 113. The conveyor belt of the block receiving conveyor belt device 115 provides a larger receiving surface as the conveying end, which can receive the block-shaped powder output from the distributing and blocking roller 112, and output to the output end of the material receiving conveying mechanism 113 at the conveying end of the block receiving conveyor belt device 115 under the action of gravity, and then output to the material collecting hopper 114 by the conveying end of the material receiving conveying mechanism 113.

[0080] Optimally, the closing opening 130 is provided with multiple.

[0081] That is, the closing opening 130 is provided with multiple. Multiple block guiding plates 132 are arranged along the conveying direction of the block conveying mechanism 12, for example, multiple closing openings 130 are arranged between the first block pressing roller 131 and the second block roller 133. Multiple closing openings 130 can cause the block-shaped powder to be extruded from the outside to the inside multiple times on both sides in the conveying direction. After the block-shaped powder is extruded, the calendering effect is formed in the middle, and multiple closing openings 130 can make the texture more complex and further elongated, thereby improving the calendering effect.

[0082] Optimally, the block compacting mechanism 13 further comprises a calendering powder supplementing device 134.

[0083] The output end of the calendering powder supplementing device 134 is located at the conveying end of the block conveying mechanism, specifically between the closing opening 130 and the second block roller 133, and the calendering powder supplementing device 134 is used to output dry powder.

[0084] The calendering powder supplementing device 134 can supplement dry powder to the blocky powder between the closing opening 130 and the second block forming roller 133, and can output the dry powder to the surface of the blocky powder. Since the blocky powder has been formed with a pattern, the dry powder can be supplemented to the cracks formed after extrusion, or can be added along the pattern, so that the pattern is more three-dimensional and more obvious, and the thickness of the blocky powder can be controlled in the extrusion gap 1311. Thus, the blocky powder supplemented with powder passes through the extrusion gap 1311 of the second block forming roller 133 again, and the second block forming roller 133 rolls down the blocky powder supplemented with powder, so that the blocky powder is more solid and the calendering effect is not easy to collapse.

[0085] The block forming and compacting mechanism 13 further comprises a second block forming roller 133.

[0086] The first block forming roller 131, the block guide plate 132, and the second block forming roller 133 are sequentially distributed along the conveying direction of the block conveying mechanism 12. The second block forming roller 133 forms an extrusion gap 1311 with the conveying end of the block conveying mechanism 12. The second block forming roller 133 can further roll the blocky powder, so as to form a calendering structure again and further improve the calendering effect.

[0087] The block forming and compacting mechanism 13 further comprises a second block forming roller 133.

[0088] The turning-over mechanism 15 comprises a turning-over conveying device 151 and a turning-over pressing roller 152.

[0089] The conveying end of the turning-over conveying device 151 passes below the conveying end of the block conveying mechanism 12. The turning-over pressing roller 152 is located above the conveying end of the turning-over conveying device 151 and forms a turning-over pressing gap. The conveying end of the discharging conveying mechanism 14 is provided with a receiving mold, and the discharging conveying mechanism 14 drives the receiving mold to move below the conveying end of the turning-over conveying device 151.

[0090] The blocky powder falls to the turning-over conveying device 151 from the conveying end of the block conveying mechanism 12 under the action of gravity after the calendering and forming of the blocky powder, and the blocky powder is turned over during the falling process. When the blocky powder is conveyed by the block conveying mechanism 12, the blocky powder is turned over by nearly 90° after being output from the conveying end of the block conveying mechanism 12. The blocky powder after turning over passes through the turning-over pressing roller 152 first, and the blocky powder passes through the turning-over pressing gap below the turning-over pressing roller 152. The turning-over pressing roller 152 and the conveying end of the turning-over conveying device 151 jointly press the blocky powder, and the turning-over pressing roller 152 rolls the blocky powder again, so that the different color powders can produce fusion, transition and extension texture, thereby further improving the calendering effect of the powder.

[0091] The discharging conveying mechanism 14 is further included.

[0092] The conveying end of the discharging conveying mechanism 14 is below the conveying end of the turnover conveying device 151.

[0093] The block forming and compacting mechanism 13 further includes a distributing tooth plate 135.

[0094] The distributing tooth plate 135 is arranged at the conveying end of the turnover conveying device 151.

[0095] The edge of the distributing tooth plate 135 is provided with a tooth structure. When the block-shaped powder passes through the conveying end of the turnover conveying device 151, the block-shaped powder will be transferred to the conveying end of the discharging conveying mechanism 14 under the action of gravity. The distributing tooth plate 135 arranged at the conveying end of the turnover conveying device 151 can cut the block-shaped powder when the block-shaped powder is about to fall, so that the block-shaped powder after turnover is divided into several small blocks and transferred to the receiving mold of the discharging conveying mechanism 14.

[0096] The discharging conveying mechanism 14 is further included. The conveying end of the discharging conveying mechanism 14 is below the conveying end of the turnover conveying device 151.

[0097] The block forming and compacting mechanism 13 further includes a hollow plate 136.

[0098] The hollow plate 136 is provided with a hollow opening. The hollow plate 136 is arranged at the conveying end of the turnover conveying device 151.

[0099] The hollow plate 136 is provided with a hollow opening. When the block-shaped powder passes through the conveying end of the turnover conveying device 151, the block-shaped powder will be output to the conveying end of the discharging conveying mechanism 14 under the action of gravity. The block-shaped powder is positioned to the conveying end of the discharging conveying mechanism 14 according to the distribution of the hollow opening.

[0100] The receiving conveying mechanism 113, the block conveying mechanism 12, the discharging conveying mechanism 14 and / or the turnover conveying device 151 are preferably conveyor belt devices.

[0101] The conveyor belt device generally synchronously connects the driving wheel and the driven wheel by using the conveyor belt, and drives the driving wheel to rotate by using the motor, so that the conveyor belt is driven to rotate under the synchronous action of the driven wheel, and the straight line segment of the conveyor belt moves horizontally to form the conveying end of the receiving conveying mechanism 113. The advantage of using the conveyor belt device is that the powder can be directly received on the conveyor belt.

[0102] The conveying belt device is generally used to connect the driving wheel and the driven wheel in synchronous rotation by the conveying belt, and uses the motor to drive the driving wheel to rotate, so that the conveying belt is driven to rotate under the synchronous action of the driven wheel, and the straight line segment of the conveying belt moves horizontally to form the conveying end of the block conveying mechanism 12. The advantage of using the conveying belt device is that the powder can be directly received on the conveying belt.

[0106] The top texture mechanism 32 comprises: a top texture block 321 and a top texture driver 322.

[0107] The output end of the top texture driver 322 is connected to the top texture block 321, for driving the top texture block 321 to move up and down to abut against the conveying end of the top texture conveying mechanism 31 or the soft pad 30, so that the top texture block 321 lifts the local area of the soft pad 30.

[0108] The present scheme sets the soft pad 30 on the conveying end of the top texture conveying mechanism 31, and sets a plurality of top texture mechanisms 32 below the soft pad 30, and the top texture block 321 of the top texture mechanism 32 lifts the soft pad 30 from bottom to top, so that the blocky powder of the soft pad 30 forms cracks on the surface under the lifting action, thereby forming the crack effect of the ecological stone, and solving the problems of color not blending, transition not natural, and no calender texture effect in the dry forming of the ecological stone.

[0109] Specifically, since the present scheme is for dry processing of ecological stone, it has formed a blocky powder at the front end, and the conveying end of the top grain conveying mechanism 31 receives the blocky powder; the conveying end of the top grain conveying mechanism 31 is connected to the output end of the calender forming device 01 (such as the conveying end of the block conveying mechanism 12, the conveying end of the turnover conveying device 151, and the conveying end of the discharge conveying mechanism 14); hereinafter, the block conveying mechanism 12 is taken as an example, the top grain conveying mechanism 31 and the block conveying mechanism 12 can be horizontally connected, or the conveying end of the top grain conveying mechanism 31 can fall to the block conveying mechanism 12 by gravity. The conveying end of the top grain conveying mechanism 31 is pre-laid with a soft pad 30, and when the blocky powder output by the block conveying mechanism 12 is received, the blocky powder is directly placed on the soft pad 30; a plurality of top grain mechanisms 32 are arranged below the conveying end of the top grain conveying mechanism 31, and the plurality of top grain mechanisms 32 are arrayed, with one top grain mechanism 32 corresponding to one area of the soft pad 30; the soft pad 30 can also correspond to one or several top grain mechanisms 32 before or after the conveying end of the top grain conveying mechanism 31 moves. The top grain driver 322 drives the top grain block 321 to move up and down, and drives the top grain block 321 to abut against a certain area of the conveying end of the top grain conveying mechanism 31 or a certain area of the soft pad 30, so that the local soft pad 30 is directly or indirectly lifted, thereby making the local blocky powder move upward, and then making the local blocky powder be lifted, while the remaining positions that are not lifted remain in contact with the conveying end of the top grain conveying mechanism 31 under gravity, and a crack is formed between the lifted area and the non-lifted area of the blocky powder; then the top grain driver 322 resets, so that the top grain block 321 is separated from the conveying end of the top grain conveying mechanism 31 or the soft pad 30, and the soft pad 30 resets under the action of gravity, and the local blocky powder that is lifted sinks; in this way, the blocky powder can form a crack in dry forming. Wet processing adds water or other organic solvents to the powder, so the viscosity is large, and when the powder is lifted from bottom to top, the difference between the lifted area and the non-lifted area of the powder is small, and no crack is formed; the present scheme uses the soft pad 30 for dry processing, which mainly loads the blocky powder and prevents the blocky powder from falling; at the same time, the soft pad 30 allows any area to deform, so that the blocky powder can have a height difference in any area, and since there is no bonding between the lifted area and the non-lifted area of the blocky powder, a crack is formed in the local area. Furthermore, the soft pad 30 is soft, and after being lifted, the blocky powder and the soft pad 30 fall to the conveying end of the top grain conveying mechanism 31 under the action of their own gravity, so the same area of the blocky powder in dry processing can be lifted multiple times to adjust the size and depth of the crack. Furthermore, the soft pad 30 is very suitable for dry processing of ecological stone, because the surface of the blocky powder has no adhesion, and the blocky powder will not be bonded to the surface of the soft pad 30, so it is easier to separate subsequently.

[0110] The top-texture driver 322 is a mechanism with a lifting function, such as a cylinder, an oil cylinder, a combination of a motor and a screw rod, a mechanical arm, etc.

[0111] Optimally, the top-texture forming device 03 further comprises a top-texture powder supplementing device 33.

[0112] The top-texture powder supplementing device 33 is located above the conveying end of the top-texture conveying mechanism 31. The top-texture powder supplementing device 33 is provided with a top-texture powder supplementing nozzle 331 for outputting dry powder, which moves above any area of the soft pad 30. The top-texture powder supplementing device 33 is internally provided with powder, which can be supplemented to any area of the block-shaped powder in the soft pad 30 as needed. The dry powder can be supplemented into the cracks to control the depth of the cracks, can be added along the outer edge of the cracks to make the texture more three-dimensional and more obvious, and can be filled in the obviously defective positions to temporarily repair the specific area of the block-shaped powder.

[0113] The movement of the top-texture powder supplementing nozzle 331 can be achieved by a mechanism with a linear movement function, such as a cylinder, an oil cylinder, a moving trolley, etc.

[0114] Optimally, when the top-texture block 321 lifts the soft pad 30 or after lifting, the top-texture powder supplementing nozzle 331 moves to the lifted area of the soft pad 30, and the output end of the top-texture powder supplementing nozzle 331 faces the lifted area.

[0115] When the top-texture block 321 lifts, the top-texture powder supplementing nozzle 331 can be moved to the lifted area of the soft pad 30 synchronously, and the powder can be supplemented directly in the lifted area when the block-shaped powder is lifted to generate cracks. This method can supplement the powder to the depth direction of the cracks during the crack lifting operation, and can mainly add the powder near the cracks. Thus, for the crack forming of the ecological stone dry method, the different powder supplementing methods of the top-texture powder supplementing nozzle 331 can further regulate the three-dimensional structure of the cracks of the ecological stone.

[0116] Optimally, the top-texture mechanism 32 further comprises a top-texture controller.

[0117] The top-texture controller is communicatively connected to a plurality of top-texture drivers 322.

[0118] The plurality of top-texture drivers 322 arranged in a line simultaneously drive the top-texture block 321 to rise, and a plurality of areas of the soft pad 30 are simultaneously lifted.

[0119] The top texture controller can directly control any one of the top texture drivers 322 to start, so that the scheme can use the top texture controller to control the driving of multiple top texture drivers 322 to start simultaneously according to needs, so as to simultaneously drive multiple top texture blocks 321 to rise; and since the top texture drivers 322 are distributed in an array, one of the top texture drivers 322 and the top texture drivers 322 in front, behind, left, right, left front, left rear, right front or right rear thereof form a linear arrangement structure, so that when multiple top texture drivers 322 arranged in a line simultaneously drive the top texture blocks 321 to rise, it is equivalent to multiple soft pads 30 being simultaneously lifted in a linear area, so that the blocky powder of the soft pad 30 can be lifted linearly, so as to form a crack of a specific length in the blocky powder, and the length of the crack can be controlled according to the number of top texture drivers 322 started, so as to realize the effect that the length of the crack of the ecological stone is controllable. The crack can be a straight line, a curved line, or an irregular multi-segment line. One set of linearly arranged top texture drivers 322 corresponds to one crack, and multiple sets of linearly arranged top texture drivers 322 can be simultaneously driven to start, so that the blocky powder is simultaneously formed with multiple sets of non-intersecting cracks.

[0120] The top texture controller can be a computer, a mobile phone, a control panel or the like.

[0121] Optimally, the soft pad 30 is a leather or rubber pad.

[0122] The soft pad 30 of the scheme can be made of a publicly known material that can be locally deformed according to needs, as long as it is a soft material, such as a leather, plastic film, paper or rubber pad. The scheme optimally uses leather and rubber, which have moderate weight and strength, are very suitable for long-term use, and can fall together with the blocky powder under the action of gravity to the conveying end of the top texture conveying mechanism 31 when being lifted, and have a certain buffering effect when falling.

[0123] The conveying end of the top texture conveying mechanism 31 is provided with a lifting hollow part 310; and the output end of the top texture driver 322 lifts through the lifting hollow part 310.

[0124] The top hollow part 310 is a hollow area of the top pattern conveying mechanism 31, which can expose the lower top pattern block 321, so as to directly lift the soft pad 30 at multiple local positions under the soft pad 30 by the top pattern block 321. For example, in one embodiment, the top pattern conveying mechanism 31 is a conveying belt structure, multiple rotating wheels are respectively installed on rotating shafts, the rotating wheels of two rotating shafts are synchronously connected by a conveying belt, each conveying belt is spaced apart, and the top hollow part 310 is formed at the spaced apart position. For example, in one embodiment, the top pattern conveying mechanism 31 is a conveying belt structure, a driving wheel and a driven wheel are synchronously connected by a conveying belt, and the top hollow part 310 is arranged on the conveying belt.

[0125] Optimally, the top pattern conveying mechanism 31 comprises a top pattern conveying frame 311, a top pattern conveying driving wheel 312, a top pattern conveying driven wheel 313, a top pattern conveying belt 314, a top pattern conveying bottom plate 315 and a top pattern conveying driver 316.

[0126] The top pattern conveying driving wheel 312 and the top pattern conveying driven wheel 313 are rotatably installed on the top pattern conveying frame 311; the top pattern conveying belt 314 synchronously connects the top pattern conveying driving wheel 312 and the top pattern conveying driven wheel 313; the soft pad 30 is transversely arranged on the top pattern conveying belt 314; the upper surface of the top pattern conveying bottom plate 315 upwardly supports the soft pad 30; and the output end of the top pattern conveying driver 316 is connected to the top pattern conveying driving wheel 312, so as to drive the top pattern conveying driving wheel 312 to rotate and drive the soft pad 30 on the top pattern conveying belt 314 to move.

[0127] The top pattern conveying bottom plate 315 and the top pattern conveying belt 314 are respectively provided with the top hollow part 310; and the top pattern block 321 is arranged on the soft pad 30 after moving through the top hollow part 310.

[0128] The top grain conveying driving wheel 312 and the top grain conveying driven wheel 313 are rotatably installed on the top grain conveying frame 311 to expand the top grain conveying belt 314; when the top grain conveying driver 316 is started, the output end of the top grain conveying driver 316 drives the top grain conveying driving wheel 312 to rotate, and the top grain conveying driven wheel 313 is driven to rotate under the synchronous action of the top grain conveying belt 314, the top grain conveying belt 314 rotates, and the straight section above the top grain conveying belt 314 moves, thereby forming the conveying end of the top grain conveying mechanism 31. The straight section above the top grain conveying belt 314 can be parallel to and close to the upper surface of the top grain conveying bottom plate 315; when the soft pad 30 and the blocky powder are heavy, the top grain conveying belt 314 can be downwardly abutted on the upper surface of the top grain conveying bottom plate 315, the upper surface of the top grain conveying bottom plate 315 can upwardly support the soft pad 30, and the vibration of the top grain conveying belt 314 caused by the rebound of the top grain conveying belt 314 when the blocky powder sinks after being lifted can be avoided, thereby avoiding the damage of the grain caused by the blocky powder of the soft pad 30.

[0129] Optimally, the top grain texture device 03 further comprises a top grain blanking mechanism 34.

[0130] The top grain blanking mechanism 34 comprises a blanking guide plate 341, a top grain blanking mold frame 342, and a blanking horizontal driver 343.

[0131] The conveying end of the top grain conveying mechanism 31 gradually inclines downward to be close to the top of the top grain blanking mold frame 342; the blanking guide plate 341 is obliquely arranged; the conveying end of the top grain conveying mechanism 31 is butted at the upper end of the blanking guide plate 341, the lower end of the blanking guide plate 341 extends into the blanking mold cavity 3421 of the top grain blanking mold frame 342; the blanking horizontal driver 343 is used to drive the top grain blanking mold frame 342 to move horizontally relative to the top grain conveying mechanism 31, so that the blanking guide plate 341 moves relative to the blanking mold cavity 3421.

[0132] The present scheme is applied to the top crack texture step in the ecological stone dry processing. Since the viscosity between the blocky powder is very low, when the blocky powder is transferred between the conveying mechanisms, the blocky powder may collapse in the gap between the conveying mechanisms, thereby causing the texture formed by the ecological stone dry forming to be damaged. In view of this, the present scheme uses a top texture blanking mechanism 34 for ecological stone dry processing. The top texture conveying mechanism 31 is downwardly inclined at the conveying end, and the conveying end is the main position where the soft pad 30 is output by the top texture conveying mechanism 31. Therefore, the soft pad 30 is integrally downwardly inclined at the conveying end, so that the blocky powder can be kept downwardly inclined to enter the blanking die cavity 3421 of the top texture blanking die frame 342. At the same time, the conveying end of the top texture conveying mechanism 31 is connected to the inclined upper end of the blanking guide plate 341, and the blocky powder can fall downwardly along the blanking guide plate 341 under the action of gravity and be guided into the blanking die cavity 3421 of the top texture blanking die frame 342. At the same time, the blanking horizontal drive 343 is started, the output end of the blanking horizontal drive 343 is connected to the top texture blanking die frame 342 and / or the top texture conveying mechanism 31, the top texture blanking die frame 342 and / or the top texture conveying mechanism 31 are driven to move, so that the relative horizontal movement between the top texture blanking die frame 342 and the top texture conveying mechanism 31 occurs, thereby driving the blanking guide plate 341 to move relatively to the blanking die cavity 3421, and then the blanking guide plate 341 gradually fills the blocky powder in the blanking die cavity 3421 in the process of relative movement, so that the texture formed by the ecological stone dry process can be kept after being loaded into the top texture blanking die frame 342.

[0133] The blanking horizontal drive 343 is a mechanism with a horizontal movement function, such as a cylinder, an oil cylinder, a combination of a motor and a screw rod, a mechanical arm, etc.

[0134] Optimally, the upper end and the lower end of the blanking guide plate 341 are connected by an arc surface 3411, the lower end of the blanking guide plate 341 abuts against the bottom wall of the blanking die cavity 3421, and the included angle between the arc surface 3411 and the bottom wall of the blanking die cavity 3421 is 0-45°.

[0135] The upper end and the lower end of the blanking guide plate 341 are connected by an arc surface 3411, the arc surface 3411 makes the blocky powder fall along the inner wall of the arc surface 3411, the angle of the blocky powder gradually changes, the direction of the speed of the blocky powder changes from 45° to 0° with the angle a of the bottom wall of the blanking die cavity 3421, and the angle of the blocky powder when entering the blanking die cavity 3421 is parallel to the bottom wall of the blanking die cavity 3421, so that the position between the top layer and the bottom layer of the blocky powder when the blocky powder enters the blanking die cavity 3421 at an inclined angle is prevented from changing, and then the texture formed by the ecological stone dry forming is prevented from changing.

[0136] Optimally, the lower end of the blanking guide plate 341 and the inner side wall of the blanking die cavity 3421 form a gap.

[0137] The blanking guide plate 341 can preferably form a gap between the lower end of the blanking guide plate 341 and the inner side wall of the blanking die cavity 3421, and the blocky powder still forms a gap with the inner side wall of the blanking die cavity 3421 after reaching the blanking die cavity 3421, which can facilitate subsequent filling of the powder in the gap, can also press the two sides of the blocky powder from the outside to the inside in the gap to adjust the texture, and can also prevent the blocky powder from leaking out of the blanking die cavity 3421 due to excessive amount, so that the relative position between the lower end of the blanking guide plate 341 and the inner side wall of the blanking die cavity 3421 can make the subsequent processing of the blocky powder more flexible.

[0138] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and purposes of the present application, and the scope of the present application is defined by the claims and their equivalents.
