[0017] The nano stone slab production device provided in the embodiment has at least the following technical effects or advantages:
[0018] 1, compared with the production problems of the previous nano stone slab production device in the distribution, flattening and pressing process of fine powder;
[0019] 1) the distribution mechanism in the embodiment divides the distribution hopper into upper half and lower half, sets the first inclined part between the upper half and the lower half, sets the second inclined part on the lower half, uses the double inclined part design of the first inclined part and the second inclined part, overcomes the characteristics of fine powder, such as light weight, poor flowability and easy agglomeration, distributes and guides the fine powder on the inner wall of the distribution hopper, solves the problem of incomplete distribution and poor powder guiding effect caused by the overall structure of the previous distribution hopper being set as vertical surface or inclined surface;
[0020] Moreover, the embodiment of the present application arranges several cloth vibrators on the surface of the first and second inclined parts and along the length direction, so that the fine powder in the cloth hopper falls more completely and quickly onto the cloth roller under the vibration force of the cloth vibrator, solves the problem that the fine powder cannot be completely discharged due to the frequent residue of the fine powder on the inner wall of the cloth hopper and the uneven distribution of the cloth when only relying on the gravity of the fine powder for discharging, and makes the fine powder more evenly distributed on the conveying belt under the rotation of the cloth roller, provides the initial sliding speed for the fine powder, and improves the uniform distribution speed and efficiency of the fine powder.
[0021] 2) In the embodiment of the present application, the leveling mechanism is arranged on both sides of the frame one, the vibration frame is arranged on both sides of the frame one, the vibration steel wire is arranged transversely on the transmission direction of the powder belt, and then the leveling vibrator is arranged on the vibration frame. The vibration force of the leveling vibrator drives the vibration frame and the vibration steel wire to vibrate the green body obtained after the distribution of the powder belt. The leveling plate is replaced by the leveling vibrator. By using the vibration frequency and amplitude of the vibration steel wire, the problem of inconsistent flatness and uneven surface of the fine powder during leveling is overcome, and the flatness and density of the surface of the green body are further improved, and the defects of deformation and cracking of the green body are reduced.
[0022] 3) In the embodiment of the present application, the belt group of the pressing mechanism adopts a structure design without horizontal ribs, replacing the pressing belt three with horizontal ribs in the prior art. After the combination and assembly of the pressing belt three without horizontal ribs and the pressing belt four, the forming concave die arranged on the side surface of the pressing belt four leaves an exhaust port. When the powder belt is driven by the press from bottom to top, the upper pressing part of the pressing belt one corresponds to the lower pressing part of the powder belt, and the forming concave die presses the green body obtained after leveling on the powder belt, and the gas in the green body can be discharged from the exhaust port, overcoming the problem that the gas in the green body cannot be smoothly discharged due to the poor flowability of the green body obtained after leveling and the hollow powder characteristics.
[0023] This solves the problem that the pressing belt three of the belt group in the press mechanism in the prior art is provided with horizontal ribs, the forming concave die is formed into a fully enclosed frame-shaped concave die, and the gas in the green body cannot be smoothly discharged during pressing and processing. The green body has many bubbles in the interior, which affects the forming quality of the green body. Therefore, through the optimization design of the pressing mechanism, the processing complexity and cost of the pressing belt three are reduced, and the defects of low bending strength, deformation and cracking caused by low density of the green body are further reduced.
[0024] 2. In the past, the discharge port of the fabric hopper was usually closed or opened by manually operating a brake plate, which was both time-consuming and labor-intensive. In this embodiment, a cylinder and a baffle are set on the front side of the fabric hopper. The cylinder controls the baffle to close or open the discharge port. The automated control of the baffle saves time and labor and prevents the problem of incomplete closing or opening by human error.
[0025] 3. Compared to the previous leveling mechanism which used a horizontally fixed leveling plate and could only level blanks of a specific thickness on the powder conveyor belt, the vibration frame of the leveling mechanism in this embodiment is adjustablely connected to the leveling mounting frame via an adjustment component. This allows the vibration frame to be positioned below the leveling mounting frame and above the powder conveyor belt via the leveling adjustment rod of the adjustment component. By turning the first nut and the second nut, the leveling adjustment rod is rotated, thereby causing the vibration frame to rise and fall to a specified height before leveling. This satisfies the leveling requirements of the vibrating steel wire for blanks of different thicknesses on the powder conveyor belt, thereby improving the operability and application range of the leveling mechanism.
[0026] 4. In this embodiment, a second frame is arranged at the discharge end of the first frame. A scraping mechanism is set between the first and second frames to replace the previous passive roller. A scraping assembly is set on the receiving hopper of the scraping mechanism. The scraping strip of the scraping assembly is used to scrape off the powder from the blank obtained after pressing. This solves the problem that the previous passive roller lacked measures to remove powder from the surface of the blank. The blank that has just been pressed by the press mechanism has too much powder on its surface, which affects the flatness of the blank. Therefore, after the powder is scraped off the surface of the blank by the scraping strip, the surface of the blank is flatter. It also prevents the blank on the subsequent blank conveyor belt from being covered with powder and affecting the surface flatness. This improves the processing quality of the blank, reduces defective products, and saves costs.
[0027] 5. In this embodiment, a third frame is arranged in the direction of the discharge end of the second frame. A chamfering mechanism is provided on the discharge end of the second frame, and a transition shaft is provided between the second and the third frame. The angle between the milling cutter of the chamfering mechanism and the horizontal plane of the blank is 30~50°. The milling cutter rotates under the control of the driver and uses the threaded chamfering part on the milling cutter to chamfer the edge of the blank. This solves the problem of excessive roughness and easy corner breakage when using a disc grinding wheel to chamfer the edge of the blank in the past, thereby achieving smooth and high-quality chamfering of the edge of the blank.
[0028] This application provides a method for producing nano-stone slabs, which has at least the following technical effects or advantages:
[0029] The method for producing the nano stone slab in the embodiment of the application is characterized in that: the method comprises the following steps: arranging the extremely fine powder material through the arrangement mechanism, the material leveling mechanism and the material pressing mechanism on the first rack in sequence along the conveying direction of the extremely fine powder material, and performing material leveling and material pressing processing on the nano stone slab blank obtained after the arrangement of the extremely fine powder material.
[0030] In the production and processing procedure of the nano stone slab, the extremely fine powder material is fully arranged and guided through the double-inclination design of the first inclined part and the second inclined part of the material hopper in the arrangement mechanism, and then the material roller is arranged directly below the lower half of the material hopper, so that the extremely fine powder material falling on the material roller in the material hopper is uniformly arranged on the powder material belt; therefore, the uniformity, flowability, material arrangement quality and efficiency of the extremely fine powder material are improved in the material arrangement procedure.
[0031] For the nano stone slab blank obtained after the arrangement, when the material leveling mechanism is used to perform the material leveling processing in the material leveling mechanism procedure, the vibration frame drives the vibration steel wire to vibrate and level the blank under the action of the vibration force of the material vibrator, so that the efficiency of the blank material leveling procedure is improved; moreover, the characteristics of the extremely fine powder material, such as light weight, poor flowability and easy agglomeration, are overcome, the flatness and density of the blank surface are improved, and the defects, such as low bending strength, deformation and cracking, caused by the low density of the blank body are reduced.
[0032] For the nano stone slab blank obtained after the material leveling, when the material pressing mechanism is used to perform the material pressing processing in the material pressing mechanism procedure, the material pressing belt three of the belt set in the material pressing mechanism is designed as a structure without horizontal protruding ribs, so that the forming concave die of the belt set is provided with an exhaust port, the gas in the blank can be discharged without obstruction when the blank is pressed, the forming quality of the blank in the material pressing procedure is improved, and the problems of repeated pressing processing of the blank or defective products are avoided; moreover, the problem of the gas existing in the blank due to the poor flowability of the blank obtained after the material leveling and the characteristics of the hollow powder material is further overcome, and the defects, such as low bending strength, deformation and cracking, caused by the low density of the blank body are further reduced.

[0054] Specifically, the fabric feeding mechanism 30 includes a fabric hopper 302, a fabric roller 303, and a fabric vibrator 304. The fabric hopper 302 is vertically positioned above the frame 10 and is divided into an upper half 3021 and a lower half 3023. The thickness of the upper half 3021 is greater than the thickness of the lower half 3023, forming a first inclined portion 3025 between them.

[0057] The leveling mechanism 40 has a vibrating frame 402, a vibrating steel wire 403, and a leveling vibrator 404. The vibrating frame 402 includes a connecting plate one 4021 and a connecting plate two 4022. The connecting plate one 4021 is an E-shaped plate arranged in a vertical direction, and the upper side of the connecting plate one 4021 is connected with the leveling frame. The connecting plate two 4022 is a strip-shaped plate, and is horizontally fixed on the lower side of the connecting plate one 4021, so as to form the vibrating frame 402 arranged in a vertical direction. Therefore, the vibrating frame 402 is arranged in a vertical direction on both sides of the rack one 10, the vibrating steel wire 403 is horizontally installed on the connecting plate two 4022 of the vibrating frame 402, and the vibrating steel wire 403 is arranged in the transmission direction of the powder belt 20, and the leveling vibrator 404 is installed on the connecting plate two 4022 of the vibrating frame 402.
[0058] When the leveling vibrator 404 is started, the leveling vibrator 404 transmits vibration force to the vibrating frame 402 and the vibrating steel wire 403, so that the vibrating steel wire 403 generates vibration frequency and amplitude, so as to vibrate and level the green body obtained after the powder on the powder belt 20 is distributed through the vibrating steel wire 403. The leveling vibrator 404 adopts a pneumatic vibrator, and the model of the pneumatic vibrator is GT-16 series of the brand of Shuo Zhou.
[0059] The pressing mechanism 50 has a belt set 502 and a press 503. The belt set 502 is movably arranged above the rack one 10 through a pressing mounting frame 501, the pressing mounting frame 501 is an annular hollow structure and is fixedly connected with the rack one 10, a plurality of rotating drums are arranged on the pressing mounting frame 501 in the annular direction, the belt set 502 is sleeved on the rotating drums of the pressing mounting frame 501 and can rotate in the annular direction. The belt set 502 is also located above the powder belt 20, when the belt set 502 and the powder belt 20 are close to each other, the position of the close is the pressing station.

The pressing belt one 5021 and the pressing belt two 5022 are located on the port of the forming concave die 5025, so the forming concave die 5025 will be separated by the pressing belt one 5021 and the pressing belt two 5022, and then cooperate with the powder belt 20 to press the blank. Therefore, the pressing belt one 5021 and the pressing belt two 5022 are made of materials with good elasticity to ensure that the pressing belt one 5021 and the pressing belt two 5022 can deform and fit in the inner wall of the forming concave die 5025 when the forming concave die 5025 cooperates with the powder belt 20 to press the blank.
[0062] The side of the powder belt 20 facing the rack one 10 is the inner surface, and the side of the powder belt 20 away from the rack one 10 is the outer surface. The inner surface of the powder belt 20 has a plurality of lower pressing portions 2011.

Moreover, the forming concave die 5025 cooperates with the powder belt 20 to press the blank obtained after flattening, and the exhaust port facilitates the blank to exhaust the gas in the blank, so as to prevent the blank from accumulating too much gas bubbles in the blank, which affects the forming quality of the blank.
[0063] The nano stone plate production device provided in the embodiment of the application has at least the following technical effects or advantages.
[0064] 1. Compared with the production problems of the previous nano stone plate production device in the processes of powder distribution, powder leveling and powder pressing;

The double inclined part design of the first inclined part 3025 and the second inclined part 3026 overcomes the characteristics of the fine powder, such as light weight, poor flowability and easy agglomeration, and performs distribution and guidance on the fine powder on the inner wall of the distribution hopper 302. The problem of incomplete distribution and poor powder guiding effect caused by the overall structure of the previous distribution hopper 302 being arranged as a vertical surface or an inclined surface is solved.
[0066] Moreover, in the embodiment of the application, a plurality of distribution vibrators 304 are arranged on the surface of the first inclined part 3025 and the second inclined part 3026 and along the length direction. Under the action of the vibration force of the distribution vibrator 304, the fine powder in the distribution hopper 302 falls more completely and quickly onto the distribution roller 303, and the problem of incomplete distribution and uneven distribution caused by the previous method of relying only on the gravity of the fine powder to discharge the fine powder from the distribution hopper 302 is solved. The lower half 3023 of the distribution hopper 302 is arranged below the distribution roller 303. Compared with the previous method of relying only on the gravity of the fine powder to discharge the fine powder from the distribution hopper 302, after the fine powder in the distribution hopper 302 falls onto the distribution roller 303, the fine powder is more uniformly arranged on the conveying belt under the rotation of the distribution roller 303, and the initial sliding speed of the fine powder is provided, and the uniform distribution speed and efficiency of the fine powder are improved.
[0067] 2) In the embodiment of the application, the leveling mechanism 40 is arranged on both sides of the rack 10, and a vibration steel wire 403 is arranged on the vibration frame 402 in the transmission direction of the powder belt 20. Then, a leveling vibrator 404 is arranged on the vibration frame 402, and the vibration frame 402 and the vibration steel wire 403 are driven by the vibration force of the leveling vibrator 404 to vibrate the blank obtained after the powder distribution on the powder belt 20. In this way, the previous leveling plate fixed horizontally on the powder belt 20 is replaced, and the vibration frequency and amplitude of the vibration steel wire 403 are utilized to overcome the characteristics of the fine powder, such as light weight, poor flowability and easy agglomeration, and the problem of inconsistent flatness and uneven surface of the fine powder during leveling. Therefore, the flatness and density of the surface of the blank are further improved, and the defects of the blank, such as low bending strength, deformation and cracking, caused by low density are reduced.
[0068] 3) The belt set 502 of the pressing mechanism 50 in the embodiment of the present application, the pressing belt three 5023 adopts the structure design without horizontal convex ribs 50251, instead of the pressing belt three 5023 with horizontal convex ribs 50251 in the past, so that the pressing belt three 5023 without horizontal convex ribs 50251 and the pressing belt four 5024 are combined and assembled, and the forming concave die 5025 arranged on one side of the pressing belt one 5021 leaves the exhaust port 50252. When the powder belt 20 is driven by the press 503 from bottom to top to press and combine with the belt set 502, the upper pressing part 50211 of the pressing belt one 5021 corresponds to the lower pressing part 2011 of the powder belt 20, at the same time, the forming concave die 5025 presses the blank body obtained after the powder belt 20 is flattened, and the gas in the blank body can be discharged from the exhaust port 50252. Overcome the problem that the blank body obtained after flattening has poor flowability and the hollow powder has gas in its interior.
[0069] This solves the problem that the pressing belt three 5023 of the belt set 502 in the mechanism of the press 503 in the past is provided with horizontal convex ribs 50251, so that the forming concave die 5025 is formed into a fully enclosed frame-shaped die, and the gas in the blank body cannot be smoothly discharged during pressing processing; and the problem that the blank body has many bubbles in its interior, affecting the forming quality of the blank body. Therefore, through the optimization design of the pressing mechanism 50, the processing complexity and processing cost of the pressing belt three 5023 are reduced, and the defects such as low bending strength, deformation and cracking caused by low density of the blank body are further reduced.
[0070] As shown in Figures 1-3 The cloth hopper 302 is vertically installed on the rack one 10 through the square cloth mounting bracket 301, and at least two cloth hoppers 302 can be installed on each cloth mounting bracket 301. The upper half 3021 of the cloth hopper 302 is provided with an inlet 3022, and the lower half 3023 of the cloth hopper 302 is provided with an outlet 3024. The outlet 3024 is arranged on the front side of the cloth hopper 302, and the outlet 3024 is in the shape of a rectangle, so that the opening surface of the outlet 3024 is perpendicular to the horizontal plane, and the left and right ends of the opening surface of the outlet 3024 extend in the horizontal direction. Then, the cloth roller 303 is arranged horizontally below the outlet 3024. When the fine powder in the cloth hopper 302 comes out of the outlet 3024, it can directly fall on the cloth roller 303, and then, under the rotation of the cloth roller 303, the fine powder falling on the cloth roller 303 is uniformly arranged on the powder belt 20 under the centrifugal force generated by the rotation of the cloth roller 303.
[0071] The front side of the cloth hopper 302 is provided with a cylinder 306 and a baffle 307, wherein the cylinder 306 is vertically arranged in a square shape, so that one end (upper end) of the cylinder 306 is fixedly connected with the front side of the cloth hopper 302, and the other end (lower end or one end of the piston rod) of the cylinder 306 is movably connected with the baffle 307 through a curved arm.
[0072] The baffle 307 has a connecting block 3071 and a shielding block 3072, both of which are arranged in a horizontal direction, and both ends of one side (upper side) of the connecting block 3071 are movably connected with the hole seat provided on the front side of the cloth hopper 302 through a rotating shaft 7031, the other side (lower side) of the connecting block 3071 is connected with the upper side of the shielding block 3072, the lower side of the shielding block 3072 extends to the discharge port 3024, and after the connecting block 3071 and the shielding block 3072 are connected with each other, the baffle 307 is formed in an inclined manner. When the cylinder 306 is started, the surface of the shielding block 3072 is movably connected with the piston rod of the cylinder 306, so as to control the shielding block 3072 to flip to close or open the discharge port 3024.
[0073] In this way, the discharge port 3024 of the cloth hopper 302 in the prior art is usually closed or opened by manually operating a shutter, which is time-consuming and laborious. In the embodiment of the present application, the cylinder 306 and the baffle 307 are arranged on the front side of the cloth hopper 302, the baffle 307 is controlled to close or open the discharge port 3024 by the cylinder 306, and the automatic control of the baffle 307 saves time and labor, and prevents the problem of incomplete closing or opening caused by human factors.
[0074] As shown in Figure 1 , 4 In the embodiment of the present application, the vibration frame 402 is provided with at least two, and the two vibration frames 402 are vertically arranged on the two sides of the rack one 10 through the material leveling mounting frame 401. The material leveling mounting frame 401 is composed of a horizontal rectangular frame and support feet installed at both ends of the bottom of the rectangular frame, and the material leveling mounting frame 401 is fixedly connected with the two sides of the rack one 10 through the support feet, so as to be horizontally arranged on the rack one 10 and the powder belt 20.
[0075] The vibration steel wire 403 has a plurality of, and the two ends of the plurality of vibration steel wires 403 are respectively connected with the vibration frames 402 arranged on the two sides of the rack one 10, and the plurality of vibration steel wires 403 are arranged in a horizontal equidistant manner above the powder belt 20, so as to perform material leveling processing on the powder on the surface of the blank on the powder belt 20.
[0076] According to the structural design and connection relationship between the connecting plate two 4022 of the vibration frame 402 and the plurality of vibrating steel wires 403, a plurality of vibrators are arranged on the connecting plate two 4022 and away from the side of the vibrating steel wires 403, and the plurality of vibrators are equidistantly arranged along the horizontal length direction of the connecting plate two 4022, and the vibrators 404 correspond to the two ends of the vibrating steel wires 403. When the material leveling vibrator 404 is started, the vibration force is transmitted to the plurality of vibrating steel wires 403 through the connecting plate two 4022 of the vibration frame 402, so that the plurality of vibrating steel wires 403 synchronously vibrate and level the green bodies on the powder material belt 20, thereby further improving the leveling efficiency and quality of the green bodies.
[0077] In order to solve the problem that the leveling plate of the previous material leveling mechanism 40 can only level the green bodies with a specific thickness on the powder material belt 20. In the embodiment of the present application, the connecting plate one 4021 of the vibration frame 402 is movably installed on the material leveling mounting frame 401 through the adjusting assembly 405, so that the vibration frame 402 is movably arranged between the material leveling mounting frame 401 and the rack one 10.
[0078] More specifically, the adjusting assembly 405 includes a material leveling adjusting rod 4051, a first nut 4052 and a second nut 4053. The material leveling adjusting rod 4051 is arranged in a vertical direction, the upper end of the material leveling adjusting rod 4051 has a threaded portion and movably penetrates the upper surface and the lower surface of the material leveling mounting frame 401, and the lower end of the material leveling adjusting rod 4051 is fixedly connected with the connecting plate one 4021 of the vibration frame 402. Then, the first nut 4052 is arranged on the upper surface of the material leveling mounting frame 401 and is threadedly connected with the material leveling adjusting rod 4051, and the second nut 4053 is arranged on the lower surface of the material leveling mounting frame 401 and is threadedly connected with the material leveling adjusting rod 4051. Therefore, the user only needs to rotate the first nut 4052 and the second nut 4053 to make the material leveling adjusting rod 4051 ascend and descend in the vertical direction, thereby driving the vibration frame 402 to ascend to a specified height.
[0079] In this way, compared with the previous material leveling mechanism 40 which adopts a horizontally fixedly installed leveling plate and can only level the green bodies with a specific thickness on the powder material belt 20. The vibration frame 402 of the material leveling mechanism 40 of the embodiment of the present application is adjustably connected with the material leveling mounting frame 401 through the adjusting assembly 405, so that the vibration frame 402 is arranged below the material leveling mounting frame 401 and above the powder material belt 20 through the material leveling adjusting rod 4051 of the adjusting assembly 405, and the material leveling adjusting rod 4051 is rotated by rotating the first nut 4052 and the second nut 4053, thereby driving the vibration frame 402 to ascend to a specified height before leveling. In this way, the leveling demand of the vibrating steel wires 403 for the green bodies with different thicknesses on the powder material belt 20 is met, thereby improving the operability and use range of the material leveling mechanism 40.
[0080] AsFigure 1 , 5 As shown, the forming die 5025 is formed by connecting at least two protruding ribs 50251 extending along the blank conveying direction to one side of the pressure belt four 5024 facing the pressure belt one 5021 (the side of the pressure belt four 5024 connected to the pressure belt three 5023). The two protruding ribs 50251 are arranged parallel to each other, and the distance between the two protruding ribs 50251 is the width of the pressed blank. A notch is provided at the end of the pressure belt along the blank conveying direction to determine the length of the blank. An exhaust port 50252 is formed between the ends of the two protruding ribs 50251 facing the fine powder conveying direction. The protruding portion of the protruding rib 50251 is arc-shaped. By making the protruding portion of the protruding rib 50251 arc-shaped, the edges of the blank formed by the die during the pressing of the nano-stone slab can be smoother, preventing chipping at the edges of the blank.
[0081] Further describing the powder conveyor belt 20, this powder conveyor belt mainly includes a pressing belt five 201 and a pressing belt six 202. The side of the pressing belt five 201 facing the frame one 10 is its inner surface, and the side away from the frame one 10 is its outer surface. Several lower pressing portions 2011 are disposed on the inner surface of the pressing belt five 201. The pressing belt six 202 is disposed on the lower pressing portions 2011 of the pressing belt five 201. Moreover, when the press 503 drives the powder conveyor belt 20 from bottom to top to press it against the belt assembly 502, the lower pressing portions 2011 of the pressing belt five 201 correspond to the upper pressing portions 50211 of the pressing belt one 5021. Through the pressing of the upper pressing portions 50211 and the lower pressing portions 2011, the pressing and forming of the blank is achieved. The powder conveyor belt 20 is protected by the pressing belt 6 202, which further enhances the durability of the powder conveyor belt 20 and ensures the normal operation of the press 503 mechanism.
[0082] like Figure 1 , 6 As shown in Figure 7, the nano-stone slab blank obtained after being pressed by the pressing mechanism 50 will enter the scraping mechanism 60 for surface powder removal processing. Therefore, a second frame 11 is set in the discharge end direction of the first frame 10. The second frame 11 has the same structure as the first frame 10 and is set in the same conveying direction. The scraping mechanism 60 is then installed between the first frame 10 and the second frame 11 to remove surface powder from the blank obtained by the pressing mechanism 50. A blank conveyor belt 21 is movably arranged on the second frame 11 to transport the blank obtained after the powder is scraped off by the scraping mechanism 60 to the next process.
[0083] Specifically, the material scraping mechanism 60 has a material collecting hopper 601 and a material scraping assembly 602, the material scraping assembly 602 is detachably mounted on the hopper mouth 6011 of the material collecting hopper 601, of course, it is not excluded that the material scraping assembly 602 is integrally formed with the material collecting hopper 601. The material scraping assembly 602 includes a material scraping strip 6021, a support strip 6022, and a mounting frame 6023. The material scraping strip 6021 is provided with at least two strips, and the two strips are arranged in parallel with each other. The support strip 6022 is arranged along the length of the material scraping strip 6021, and the support strip 6022 is fixedly connected to the two parallel material scraping strips 6021, and the two parallel material scraping strips 6021 are fixedly connected to form a stable trapezoidal structure. The trapezoidal structure of the material scraping strip 6021 and the support strip 6022 are fixedly connected in the square mounting frame 6023, and the mounting frame 6023 is mounted on the hopper mouth 6011 of the material collecting hopper 601.
[0084] After installation, the material scraping strip 6021, the support strip 6022, the powder belt and the body belt 21 are located in the same horizontal plane, and the material scraping strip 6021 has an arc-shaped protruding portion, and the height of the protruding portion on the surface of the material scraping strip 6021 is higher than the height of the powder belt 20 and the body belt 21, so that the protruding portion can be used to scrape the powder on the surface of the body. The two material scraping strips 6021 can more fully scrape the powder on the surface of the body, thereby further improving the scraping effect of the powder on the surface of the body.
[0085] The material collecting hopper 601 is arranged in a vertical direction, and the material collecting hopper 601 has a material guiding cavity 6012 and a containing cavity 6013. The material guiding cavity 6012 constitutes the upper part of the material collecting hopper 601, and the hopper mouth 6011 is arranged at the upper end of the material guiding cavity 6012. The hopper mouth 6011 is generally rectangular, and is used to receive the powder scraped by the material scraping strip 6021 from the surface of the body. The powder on the surface of the body falls into the material guiding cavity 6012 through the hopper mouth 6011. The width of the material guiding cavity 6012 gradually narrows from top to bottom, so the width of the hopper mouth 6011 at the upper end of the material guiding cavity 6012 is relatively wide. Thus, the gap between the two sides of the hopper mouth 6011 of the material guiding cavity 6012 and the powder belt 20 and the body belt 21 is reduced. When the material scraping assembly 602 is mounted on the hopper mouth 6011, the contact area between the material scraping assembly 602 and the body is large, and the force receiving area of the body is increased. Thus, the small force receiving area of the body on the driven roller shaft and the large gap between the driven roller shaft and the two conveying belts in the prior art can be avoided, so that the body can be smoothly transitioned and the risk of deformation is reduced. Moreover, according to the structure optimization of the material guiding cavity 6012, the inner wall of the material guiding cavity 6012 is inclined to the middle part to form an inclined surface for guiding the powder to slide downward. The lower end of the material guiding cavity 6012 is connected with the containing cavity 6013, so that the powder slides into the containing cavity 6013 along the inclined surface of the material guiding cavity 6012.
[0086] A scraper suction pipe 604 is connected to each of the two sides of the receiving cavity 6013, and the scraper suction pipe 604 is connected to an exhaust fan. When the exhaust fan is started, the powder of the blank in the receiving cavity 6013 is sucked out through the scraper suction pipe 604 to avoid excessive powder accumulation in the receiving cavity 6013, which would affect the normal operation of the scraper assembly 602.
[0087] A sensor 603 is installed on the support bar 6022 of the scraper assembly 602. This sensor 603 is communicatively connected to the driver of the pressing mechanism 50. When the sensor 603 senses that the billet has been conveyed onto the scraper assembly 602, it sends a signal to the driver, causing the driver to control the pressing mechanism 50 to perform the next pressing action. This prevents the pressing mechanism 50 from experiencing irregular pressing actions, which could lead to damage to the pressing mechanism 50.
[0088] Thus, in this embodiment of the application, a scraping mechanism 60 is provided between frame 10 and frame 21, replacing the conventional passive roller. The scraping strip 6021 of the scraping assembly 602 is used to scrape off the powder from the blank obtained after pressing. This solves the problem that the conventional passive roller lacks measures to remove powder from the surface of the blank, and the blank pressed by the press 503 mechanism has excessive powder on its surface, affecting the flatness of the blank. Therefore, after the powder is scraped off the surface of the blank by the scraping strip 6021, the surface of the blank is flatter, and the problem of the blank on the subsequent blank conveyor belt 21 being covered with powder and affecting the surface flatness is prevented. This improves the processing quality of the blank, reduces defective products, and saves costs.
[0089] like Figure 1 , 8 As shown in Figure 9, the nano-stone slab blank obtained after the powder is scraped off by the scraping mechanism 60, and the relatively fragile blank before entering the kiln for baking, will undergo edge chamfering processing by the chamfering mechanism 70. Therefore, a frame three 12 is provided in the discharge end direction of the second frame 11. The second frame 11 and the third frame 12 have the same structure and are arranged in the same conveying direction. A transition shaft 80 is provided between the second frame 11 and the third frame 12, and the chamfering mechanism 70 is installed on the discharge end of the second frame 11. The chamfering mechanism 70 performs edge chamfering processing on the blank obtained after the powder is scraped off by the scraping mechanism 60. A blank conveyor belt two 22 is movably arranged on the third frame 12 for conveying the blank obtained after chamfering by the chamfering mechanism 70 to the next process.
[0090] Specifically, the chamfering mechanism 70 is movably installed on the discharging end of the rack three 12 through a chamfering mounting rack 701, the chamfering mechanism 70 has a milling cutter 702 and a chamfering driver 703, the chamfering driver 703 is an electric motor, the milling cutter 702 is in transmission connection with a rotating shaft 7031 of the chamfering driver 703, and the milling cutter 702 is synchronously driven to rotate when the rotating shaft 7031 is controlled to rotate. The milling cutter 702 further has a thread-shaped chamfering part 7021 arranged around the surface of the milling cutter 702.
[0091] The included angle between the milling cutter 702 and the blank horizontal plane is 30-50°, preferably, when the included angle between the milling cutter 702 and the blank horizontal plane is set to 45°, the thread-shaped chamfering part 7021 of the milling cutter 702 is used to chamfer the edge of the blank conveyed to the transition shaft 80, so that the best smooth chamfering effect of the edge of the blank is achieved, and the best prevention of the edge of the blank is achieved.
[0092] In this way, the milling cutter 702 rotates under the control of the chamfering driver 703, the included angle between the milling cutter 702 and the blank horizontal plane is in the range of 30-50°, and the thread-shaped chamfering part 7021 on the milling cutter 702 is used to chamfer the edge of the blank. In this way, the problem of rough chamfering of the edge of the blank by the disc-shaped grinding wheel and the problem of easy edge jumping are solved, and smooth and high-quality chamfering of the edge of the blank is achieved.
[0093] Further, the chamfering mounting rack 701 is provided with horizontally arranged mutually parallel slide rails 708 and an adjusting rod one 706 on one side of the conveying belt, and the adjusting rod one 706 is located above the slide rails 708. The chamfering driver 703 is movably installed on the slide rails 708 through a slide base one 704, and the slide base one 704 is movably connected with the adjusting rod one 706. Specifically, one end of the adjusting rod one 706 has a hand wheel, the adjusting rod one 706 is in threaded connection with two threaded hole seats on the side of the chamfering mounting rack 701, and the slide base one 704 is movably connected with the adjusting rod one 706 through threaded hole pieces between the two threaded hole seats of the mounting rack.
[0094] Therefore, the user rotates the hand wheel on the adjusting rod one 706 to control the slide base one 704 to reciprocally slide along the slide rails 708 in the direction of the slide rails 708, and then the milling cutter 702 chamfers the blank in the direction of the slide rails 708. In this way, the milling cutter 702 stably and accurately chamfers the blank in the direction of the slide rails 708.
[0095] Furthermore, to further improve the machining flexibility of the end mill 702, a second slide 705 is mounted on the first slide 704. The second slide 705 consists of a slide groove and a slide cover that are slidably connected. The slide groove is fixedly connected to the first slide 704. Then, a chamfering driver 703 for controlling the drive of the end mill 702 is mounted on the slide cover, so that the chamfering driver 703 and the end mill 702 slide relative to the slide groove and the first slide 704 following the slide cover. Moreover, an adjusting rod 707 is connected to the slide groove of the second slide 705. One end of the adjusting rod 707 has a handwheel, and the other end is movably inserted into the slide groove and threadedly connected to it. The end of the adjusting rod 707 inserted into the slide groove is also fixedly connected to the slide cover.
[0096] Therefore, since the chamfering actuator 703 is fixedly connected to the sliding cover, the user can control the sliding cover, chamfering actuator 703, and milling cutter 702 to move up and down on the slide groove or slide 704 simply by turning the handwheel on the second adjusting rod 707. This enables the milling cutter 702 to chamfer the blank of the transition shaft 80 in the vertical direction, and makes the milling cutter 702 applicable to chamfering the edges of blanks of different thicknesses, thus improving the application range of the chamfering mechanism 70.
[0097] To further process the powder generated during the chamfering of the billet, chamfering suction pipes 709 are provided at both ends of the transition shaft 80, and these pipes are connected to exhaust fans. When the exhaust fans are started, the powder generated during the chamfering of the billet is sucked off the transition shaft 80 through the chamfering suction pipes 709, so as to avoid excessive powder accumulation on the transition shaft 80, which would affect the subsequent chamfering quality of the billet.
[0098] like Figures 1-9 As shown, taking the production of nano-stone slabs from fine powder using a nano-stone slab production device as an example, the nano-stone slab production method in this application embodiment includes at least the following production steps:
[0099] S1. Fabric: The fine powder in the fabric hopper 302 of the fabric mechanism 30 is dropped sequentially along the first inclined part 3025 and the second inclined part 3026 of the fabric hopper 302 by the vibration force of the fabric vibrator 304. The fine powder falls from the second inclined part 3026 onto the fabric roller 303 located directly below the lower half 3023, and is then distributed on the powder belt 20 by the rotation of the fabric roller 303.
[0100] S2, leveling: The vibrating frame 402 of the leveling mechanism 40 vibrates under the vibration force of the leveling vibrator 404 and drives the vibrating steel wire 403 so that the vibrating steel wire 403 vibrates and levels the blank obtained after the powder belt 20 has been laid.
[0101] S3, the pressing mechanism, the belt group 502 of the pressing mechanism 50 is sequentially combined from the outside to the inside of the pressing belt one 5021, the pressing belt two 5022, the pressing belt three 5023, and the pressing belt four 5024, the pressing belt two 5022, the pressing belt three 5023, and the pressing belt four 5024 are arranged on the upper pressing part 50211 of the inner surface of the pressing belt one 5021, and the side of the pressing belt four 5024 is provided with a forming concave die 5025 with an exhaust port 50252;
[0102] When the press 503 of the pressing mechanism 50 drives the powder belt 20 to be pressed and combined to the belt group 502 from bottom to top, the upper pressing part 50211 of the pressing belt one 5021 corresponds to the lower pressing part 2011 of the inner surface of the powder belt 20, so that the forming concave die 5025 presses the green body obtained after the powder belt 20 is flattened.
[0103] S4, the scraping mechanism, the two scraping strips 6021 of the scraping assembly 602 in the scraping mechanism 60 use the convex ribs 50251 protruding from the surface of the powder belt 20 to perform surface powder scraping processing on the green body obtained after the pressing.
[0104] S5, chamfering, the milling cutter 702 of the chamfering mechanism 70 is controlled by the chamfering driver 703, and the included angle between the milling cutter 702 and the green body is in the range of 30-50°, and the thread-shaped chamfering part 7021 of the milling cutter 702 is used to chamfer the edge of the green body conveyed to the transition shaft 80 after the scraping.
[0105] The embodiment of the application provides a method for producing nano stone rock plates, and at least has the following technical effects or advantages:
[0106] In the method for producing nano stone rock plates in the embodiment of the application, the powder distributing mechanism 30, the powder flattening mechanism 40, and the powder pressing mechanism 50 are sequentially arranged on the rack one 10 along the powder conveying direction, so that the fine powder is distributed, and the nano stone rock plate green body obtained after the distribution is flattened and pressed.
[0107] In the above production and processing process of the nano stone rock plate, the fine powder is fully distributed and guided through the double-inclination design of the first inclined part 3025 and the second inclined part 3026 of the powder hopper 302 in the powder distributing mechanism 30, and then the powder roller 303 is arranged directly below the lower half 3023 of the powder hopper 302, so that the fine powder falling on the powder roller 303 in the powder hopper 302 is uniformly distributed on the powder belt 20; therefore, the uniformity, flowability, distribution quality and efficiency of the fine powder distribution in the distribution process are improved.
