[0050] The present invention combines a conveying device, a material distribution system, a glue-applying device, a press, a glue-lifting device, a curing machine and a demoulding device to form an entire ecological stone production line, which can complete the production process from ecological stone slurry distribution, to ecological stone slurry surface glue board sticking, vacuum pressing, glue-lifting board, curing and demoulding. The production line has a high degree of automation, can effectively improve the production efficiency of ecological stone slabs, can meet production needs, and reduce labor costs. The prepared ecological stone slabs have rich and clear textures and good board texture.

[0051] like Figure 2 As shown, preferably, the material distribution system 2 includes a material discharging device a1 and a material feeding device a2, the material discharging device a1 is arranged directly above the material feeding device a2, the conveying device 1 is arranged below the material feeding device a2, and the mold frame 10 is placed on the conveying device 1, the material discharging device a1 is used to discharge material to the material feeding device a2, the material feeding device a2 is used to distribute material to the mold frame 10, and the conveying device 1 is used to convey the mold frame 10 to directly below the material feeding device a2;

[0052] The material discharge device a1 comprises a plurality of material discharge hoppers a11 and a V-shaped flow guide groove a12. The plurality of material discharge hoppers a11 are arranged in parallel. The V-shaped flow guide groove a12 is arranged below the material discharge hopper a11, and the feed port of the V-shaped flow guide groove a12 is located directly below the discharge port of the material discharge hopper a11.

[0053] The feeding device a2 includes a feeding hopper a21 and a feeding and replenishing rod a22, and the feeding and replenishing rod a22 is rotatably installed on the inner side of the feeding hopper a21, and the rotation of the feeding and replenishing rod a22 is used to realize forward feeding or backward replenishing; the feeding hopper a21 is arranged below the V-shaped flow guide groove a12, and the feed port of the feeding hopper a21 is located directly below the discharge port of the V-shaped flow guide groove a12.

[0054] In the prior art, the preparation process of ecological stone generally uses a mixing device to mix a basic slurry with the basic color tone of stone slabs and a color slurry with decorative effect to form a mixed slurry, and uses a material-pickling device to poke the slurry to form a certain natural-like texture pattern. However, since the ecological stone produced by this process or equipment mainly uses the material-pickling device to form a texture pattern, and the poke track of the material-pickling device is relatively single, it has great limitations.

[0055] In order to enhance the richness of texture patterns and improve the natural-like effect of ecological stones, the material distribution system 2 includes a feeding device a1, a feeding device a2 and a mold frame 10, and its working process is as follows: the feeding hopper a11 is filled with basic slurry or color slurry, and the above two slurries can be discharged from the feeding hopper a11 at different feeding speeds, different feeding amounts or different feeding times, and then fall onto the V-shaped flow guide groove a12, thereby producing different mixing effects; then, after being conducted by the V-shaped flow guide groove a12, it falls into the feeding hopper a21, and then through the rotation of the feeding and replenishing rod a22 on the feeding hopper a21, the mixed slurry can produce different mixed textures; finally, the material with mixed texture is gradually applied to the mold frame 10, and is transported by the conveying device 1 to the next step of gluing process.

[0056] By controlling the different feeding speeds, different feeding amounts or different feeding times of the base slurry or the color slurry in the feeding hopper a11, the discharge ratio of different slurries can be controlled, which is beneficial for the slurry to produce different mixing effects and improve the texture richness; secondly, the technical solution is also provided with a rotatable feeding and replenishing rod a22 in the feeding hopper a21. Specifically, the feeding and replenishing rod a22 can rotate forward, reverse, intermittently, continuously, slowly or quickly to stir the slurry, so that the mixed slurry can produce different mixed textures, further improving the richness of the texture. Whether it is by controlling the different feeding speeds, different feeding amounts or different feeding times of the base slurry or the color slurry in the feeding hopper a11 to make the slurry produce different mixing effects, or by setting the feeding and replenishing rod a22 to stir the slurry so that the mixed slurry produces different mixed textures, the present technical solution is to guide the flow of the slurry to make the slurry produce a texture pattern. Therefore, the formed texture pattern has a natural transition, which can make the formed ecological stone more in line with the texture of natural stone, which is beneficial to improving the natural imitation effect of the ecological stone.

[0057] Preferably, the feeding hopper 21 includes a material baffle along a211 and a feeding platform a212, the vertical cross-section of the material baffle along a211 is arc-shaped, and the arc direction of the material baffle along a211 is toward the discharge port of the feeding hopper a21; the feeding platform a212 is integrally formed at the end of the material baffle along a211, and the end of the feeding platform a212 is tilted downward.

[0058] The feeding hopper a21 includes a material blocking edge a211 and a feeding platform a212. The arc-shaped material blocking edge a211 is beneficial to preventing the slurry from flowing to other places outside the feeding hopper a21, and at the same time preventing the slurry from splashing out of the feeding hopper a21 when it falls; the feeding platform a212 is integrally formed at the end of the material blocking edge a211, and the end of the feeding platform a212 is tilted downward, which is beneficial to the flow of the slurry along the feeding platform a212 under the action of gravity, thereby improving the fluidity of the slurry.

[0059] Preferably, the rod wall of the feeding and replenishing rod a22 is surrounded by a spiral blade a221, and two adjacent spiral blades a221 located in the same plane are trumpet-shaped structures;

[0060] A feeding hole is provided at the end of the material blocking edge a211, and the feeding feeding rod a22 passes through the feeding hole and is installed on the feeding hopper a21. The driving end of the feeding feeding rod a22 is connected to a feeding feeding driving device a222, and the feeding feeding driving device a222 is used to drive the rotation of the feeding feeding rod a22.

[0061] The rod wall of the feeding and replenishing rod a22 is surrounded by spiral blades a221, and the two adjacent spiral blades a221 located in the same plane are of a trumpet-shaped structure. When the feeding and replenishing driving device a222 controls the spiral blades a221 of the feeding and replenishing rod a22 to rotate toward the discharge port of the feeding hopper a21, the slurry will flow toward the discharge port of the feeding hopper a21 under the extrusion of the spiral blades a221 of the trumpet-shaped structure. At this time, the feeding and replenishing rod a22 plays a role of feeding; when the feeding and replenishing driving device a222 controls the spiral blades a221 of the feeding and replenishing rod a22 to rotate toward the feeding hole of the feeding hopper a21, the slurry will flow toward the feeding hole of the feeding hopper 21 under the extrusion of the spiral blades a221 of the trumpet-shaped structure. At this time, the feeding and replenishing rod a22 plays a role of replenishing.

[0062] The slurry discharged through the feeding hole will fall onto the advancing mold frame 10, which is helpful to ensure that the slurry fills the mold frame 10 and stabilizes the weight of the slurry.

[0063] Preferably, the material distribution system further comprises a feeding device a6, the feeding device a6 comprises a feeding box a61, a feeding hopper a62 and a fixed base a63, the feeding box a61 is installed between the material blocking edge a211 and the feeding feeding driving device a222, and a feeding port is provided at the bottom of the feeding box a61;

[0064] The feeding hopper a62 is disposed below the feeding box a61 through the fixed base a63, and the feeding port of the feeding box a61 is located directly above the feeding port of the feeding hopper a62.

[0065] The feeding device a6 includes a feeding box a61, a feeding hopper a62 and a fixed base a63. The feeding box a61 is installed between the material blocking edge a211 and the feeding feeding drive device a222. When the feeding feeding drive device a222 controls the spiral blade a221 of the feeding feeding rod a22 to rotate toward the feeding hole of the feeding hopper a21, it is beneficial to collect the slurry discharged through the feeding hole; the feeding hopper a62 is arranged below the feeding box a61 through the fixed base a63, and the feeding port of the feeding box a61 is located directly above the feeding port of the feeding hopper a62. The collected slurry enters the feeding hopper a62, which is beneficial to the feeding of the slurry in the mold frame 10 through the feeding hopper a62.

[0066] Preferably, the feeding device a2 also includes a cloth hopper a5, which is arranged below the discharge port of the feeding hopper a21, and the cloth hopper a5 can swing back and forth along the length direction of the discharge port of the feeding hopper a21; the lowest point of the discharge port of the cloth hopper a5 can be connected to the top of the mold frame 10.

[0067] The distribution hopper a5 can swing back and forth along the length direction of the discharge port of the feeding hopper a21, which can effectively increase the continuity of the slurry distribution and form continuous textures such as twill and wavy patterns, which is beneficial to increase the casting effect of slurries of different colors. The lowest point of the discharge port of the distribution hopper a5 can be connected to the top of the mold frame 10, which can effectively control the material level of the distribution hopper a5 and maintain the continuity and stability of the texture, and at the same time is beneficial to improve the pressing stability and pressing density of the slurry in the mold frame 10.

[0068] Preferably, the material distributing system 2 also includes a material dispensing device a7, which includes a mounting base a71, a material dispensing driving device a72 and a material dispensing rod a73. The material dispensing driving device a72 is installed above the mold frame 10 through the mounting base a71, and the output end of the material dispensing driving device a72 is connected to the material dispensing rod a73. The material dispensing driving device a72 drives the material dispensing rod a73 to be moved, and the material dispensing rod a73 is used to move the slurry in the feeding hopper a21.

[0069] The material distribution system 2 is provided with a material shifting device a7, and the material shifting driving device a72 drives the material shifting rod a73 to shift the slurry in the feeding hopper a21. The operator can control the material shifting driving device a72 through software, which is conducive to the realization of variable texture and special texture in the ecological stone.

[0070] like Figure 3 and Figure 4As shown, preferably, the glue lifting device 5 includes a frame b1, and the left and right beams b2 of the frame b1 are inclined upward, and the beam b2 is provided with a glue lifting and conveying device b21; the lower end of the glue lifting and conveying device b21 is connected to a glue clamping device b3; the glue lifting and conveying device b21 drives the glue clamping device b3 to slide up and down along the beam b2;

[0071] The clamping device b3 is located above the conveying device 1 , and includes a clamping hand b31 and a clamping hand column b32 . The clamping hand b31 is rotated to clamp or release the lower end surface of the clamping hand column b32 .

[0072] Before the ecological stone slab is pressed, a layer of rubber sheet will be pasted on the surface. Generally, a part of the rubber sheet will protrude from the top of the stone to facilitate the workers to lift the rubber sheet. When the conveying device 1 conveys the mold frame 10 to the rubber lifting device 5, the rubber clamping device b3 is started, and the clamping hand b31 on the rubber clamping device b3 clamps the protruding part of the rubber sheet. After the clamping hand b31 clamps the protruding part of the rubber sheet, the rubber lifting conveying device b21 is started, and the rubber lifting conveying device b21 drives the rubber clamping device b3 to move obliquely upward along the crossbeam b2 to lift the entire rubber sheet; the crossbeam b2 is tilted upward to form an angle between the lifting direction and the conveying device 1 when lifting the rubber sheet, so as to protect the rubber sheet from being broken due to excessive bending of the rubber sheet when lifting, because the rubber sheet has a certain hardness. If the rubber sheet is lifted in parallel, the connection between the unlifted rubber sheet and the lifted rubber sheet will be excessively bent. If the hardness of the rubber sheet is sufficient, the connection part will break, affecting the integrity of the rubber sheet.

[0073] Preferably, the glue clamping device b3 further includes a rotating rod b33 and a hand clamping frame;

[0074] A connecting piece b36 is installed at a spacing at the bottom of the lower frame bar b35 of the gripping frame, and the lower surface of the middle part of the connecting piece b36 is connected and fixed with the gripping column b32 through a stud; a fixing nut b37 is provided on the lower surface of the end of the connecting piece b36; and the rotating rod b33 is sleeved in the fixing nut b37;

[0075] The grippers b31 are installed on the lower surface of the rotating rod b33 at intervals through studs; the grippers b31 correspond to the gripper columns b32 one by one; the rotating rod b33 is connected to a rotating device b4; the rotating device b4 drives the rotating rod b33 to rotate.

[0076] The clamping hand b31 is a bent iron sheet, and the clamping hand b31 is on the outside of the clamping hand column b32. When the clamping device b3 is started, the rotating rod b33 rotates counterclockwise, thereby driving the clamping hand b31 to rotate; so that the top of the clamping hand b31 contacts the lower end surface of the clamping hand column b32. When working, the protruding part of the rubber sheet is just located between the clamping hand column b32 and the clamping hand b31. The clamping hand column b32 and the clamping hand b31 will cooperate to clamp the rubber sheet between the clamping hand column b32 and the clamping hand b31, completing the clamping work of the rubber sheet, and the clamping stability is strong.

[0077] Preferably, a plurality of rubber sheet recovery belts b7 are provided below the rack frame b1 , and the rubber sheet recovery belts b7 are arranged behind the conveying device 1 , and the rubber sheet recovery belts b7 are upwardly inclined moving conveyor belts.

[0078] A conveying device 1 and a rubber sheet recovery belt b7 are provided below the frame b1, and the rubber sheet recovery belt b7 is provided behind the conveying device 1. When the clamping device b3 clamps the rubber sheet and lifts it upward to the end, the end of the rubber sheet will fall on the rubber sheet recovery belt b7. Since the rubber sheet recovery belt b7 is inclined upward, and the inclination angle is greater than the inclination angle of the beam b2, when the clamping device b3 continues to transport upward, the rubber sheet will gradually approach the rubber sheet recovery belt b7, and release the clamping hand b31 at the top of the rubber sheet recovery belt b7, so that the entire rubber sheet can fall on the rubber sheet recovery belt b7, which facilitates the recycling of the rubber sheet.

[0079] Preferably, the output end of the rubber sheet recovery belt b7 is provided with a rubber sheet cleaning device 8, such as Figure 5 As shown, the rubber sheet cleaning device 8 includes a fixed bracket c1, a sewage pool c2 and a conveyor belt c3, the fixed bracket c1 is arranged above the sewage pool c2, and a driving shaft c11 and a plurality of rollers c15 are arranged on the fixed bracket c1, the driving shaft c11 is arranged at one end of the conveyor belt c3, and is used to drive the conveyor belt c3 to rotate, and the roller c15 is used to tension and support the conveyor belt c3, and rotate with the conveyor belt c3; the end of the rubber sheet recovery belt b7 is connected to the conveyor belt c3, and a plurality of conveyor belts c3 are arranged in parallel; and also includes a primary spray component c4, a brushing component c5, a water absorption component c7 and an air drying component c8 which are arranged on the fixed bracket c1 in sequence according to the conveying direction of the conveyor belt c3;

[0080] The primary spray component c4 is used to flush and clean the rubber plate;

[0081] The scrubbing component c5 is used to scrub the residue on the surface of the rubber plate;

[0082] The water absorbing component c7 is used to absorb the sewage attached to the rubber plate after scrubbing;

[0083] The air drying component c8 is used to dry the residual moisture on the rubber plate.

[0084] The viscosity of the eco-stone slurry is very high. After being pressed, the slurry easily adheres to the rubber sheet and is very difficult to clean. The rubber sheet cleaning device can quickly clean the rubber sheet with the slurry attached and can dry the rubber sheet for reuse.

[0085] After the pressing is completed, the rubber sheet is clamped and lifted from the surface of the slurry. The side of the rubber sheet with the slurry attached is placed upward and transported to the conveyor belt c3 of the rubber sheet cleaning device via the rubber sheet recovery belt b7; the conveyor belt c3 rotates following the driving shaft c11 and drives the rubber sheet to move on the rubber sheet cleaning device; the roller c15 plays the role of supporting and tensioning the conveyor belt c3 to prevent the conveyor belt c3 from bending downward under the gravity of the rubber sheet; the primary spray component c4 continuously sprays water to form a water curtain. When the rubber sheet passes by, the water curtain wets and flushes the rubber sheet attached to the conveyor belt c3. The water can dilute the slurry, reduce the viscosity of the slurry attached to the surface of the rubber sheet, facilitate subsequent scrubbing, and soften the dried slurry; then, the conveyor belt c3 drives the rubber sheet through the scrubbing component c5, and the scrubbing component c5 scrubs the side of the rubber sheet with the slurry attached to it, and brushes the slurry away from the surface of the rubber sheet; then, the conveyor belt c3 drives the rubber sheet through the water absorbing component c7, and the water absorbing component c7 absorbs the sewage attached to the rubber sheet after scrubbing; finally, the rubber sheet passes through the air-drying component c8, and the air-drying component c8 blows the moisture on its surface dry.

The sponge c72 is detachably mounted on the connecting frame c71. When the water absorption of the sponge c72 decreases or the sponge c72 is stained with residual sewage, the sponge c72 can be directly replaced to avoid affecting the drying effect or cleaning effect of the rubber sheet. The sponge can be extended backward to increase the volume to increase the water absorption amount, and at the same time, it can also increase the contact surface between the sponge and the rubber sheet to improve the water absorption effect; in addition, the sponge can also scrape the slurry remaining on the surface of the rubber sheet.

[0101] Preferably, after the mold frame moving driving assembly d2 moves the mold frame 10 horizontally to the corresponding designated demoulding position; the upper lifting frame d122 descends and drives the upper grabbing piece d5 to descend. When the bottom end surface of the upper grabbing piece d5 contacts the plate in the mold frame 10, the upper grabbing piece d5 absorbs the plate and rises, causing the plate to rise. At this time, since the mold frame and the plate are solidified together, the mold frame 10 will rise with the plate without the action of external force. However, since the upper fixed frame d121 is provided with a fixed upper demoulding device d6, the upper When the mold frame 10 follows the rise, the bottom end surface of the end demolding device d6 provides a resistance in the opposite direction of the movement of the mold frame 10, so that the upward movement of the mold frame 10 is prevented. At this time, the plate can be demolded from the mold frame 10. At the same time of demolding, the lower end supporter d3 located on the demolding lower frame will rise and protrude above the conveying surface. The top supporting surfaces of several lower end supports d3 are used to receive the mold frame 10 after demolding; the output end of the lower end supporter d3 contacts the mold frame 10 when extending out, and places the mold frame 10 on the mold frame moving drive assembly d2 when resetting.

After the mold frame is removed, the upper end lifting frame d122 is lowered, and the lower end support d3 located on the demolding lower frame will rise out of the conveying surface, and the top supporting surfaces of the several lower end supports d3 are used to receive the slab. After receiving the slab, the lower end support d3 is lowered, so that the slab can be smoothly lowered to the surface of the conveyor line. No workers are required to participate in the whole process, which improves the demolding efficiency and avoids the phenomenon that the slab is easily hit during manual placement, resulting in cracks or damage to the slab.
