Description

Technical Field

[0001] The present invention relates to the technical field of sound barriers installed on both sides of roads, and specifically relates to a fiber-reinforced sound barrier forming machine. Background Art

[0002] Sound barriers are installed on both sides of highways, high-speed railways, municipal bridges, and subway tracks. They are wall-like structures installed beside railways and roads to reduce the impact of traffic noise on nearby residents. Currently, there are many types of sound barriers, and the most common ones include ordinary metal sound barriers, aluminum alloy sound barriers, ordinary concrete sound barriers, GRC non-metal sound barriers, photovoltaic sound barriers, etc. Among them, the ordinary concrete sound barrier has an average surface density of 195 kg / m², is only used in subgrade sound barrier projects, does not generate static electricity, is relatively heavy and difficult to install, and has a service life of ≥25 years; the GRC non-metal sound barrier has an average surface density of 83 kg / m², can be used in both subgrade and bridge sound barrier projects, does not generate static electricity, is relatively light and easy to install with bolt connections, and has a service life of ≥25 years; the photovoltaic sound barrier has an average surface density of 35 kg / m², can be used in both subgrade and bridge sound barrier projects, is prone to generating static electricity, is relatively light and easy to install with bolt connections, and has a service life of ≥15 years. In recent years, a new type of ECP non-metal sound barrier, that is, a fiber-reinforced non-metal sound barrier, has emerged on the market. Its average surface density is 40 - 80 kg / m², can be used in both subgrade and bridge sound barrier projects, does not generate static electricity, is relatively light and easy to install, and has a service life of ≥30 years. This ECP non-metal sound barrier is a fiber cement board formed by high-pressure vacuum extrusion, abbreviated as ECP board. During the production process of ECP boards, the thickness of the initially shaped dry blank board, the dimensions of the top surface grooves, width, and its protruding and grooved parts do not meet the standards, and the product quality cannot be guaranteed, resulting in difficulties in smooth installation during later assembly.

[0003] In the prior art, the utility model patent with the patent number 201921580579.8 discloses a production line for producing ECP boards, belonging to the technical field of the entire production line of ECP boards. It includes the following systems arranged in sequence according to the ECP board production process: a pretreatment system for modifying solid waste residues to form modified slag materials; a mud preparation system for preparing mud using the modified slag materials as one of the raw materials; a board forming system for producing ECP dry blank boards from the mud; and a finishing system for finely processing the ECP dry blank boards into ECP finished boards. Using the production line for producing ECP boards of the present invention can achieve the purpose of producing ECP finished boards. The present invention uses solid waste residues (such as phosphogypsum) as the initial raw material, turning waste into treasure, and consuming a large amount of solid waste residues (such as phosphogypsum) that pollute the environment, thus improving the increasingly polluted natural environment. However, in the finishing system of this solution, a grinding machine is provided, but its structure is not described in detail, and there is no mention of how to grind the two side surfaces of the dry blank board to be flush.

[0004] The utility model patent with the patent number 202311683081.5 relates to a rolling integrated forming device for metal unit plates of a sound barrier, including a base and a blanking mechanism that can assist workers in transferring the rolled metal unit plates; a conveying module, a rolling module, a cutting component, and a shaping die are arranged on the base; the shaping die is fixedly installed on the top of the base and is used to assist the metal unit plate in rolling to form a shaped structure; the rolling module can roll and shape the metal unit plate; the conveying module can drive the metal unit plate to move on the shaping die; the cutting component can equally divide and cut the metal raw material. The present invention mainly drives the groove rod to swing through a reciprocating motor, pushes the push plate to the left, pushes the metal unit plate onto the hook post, and lowers the metal unit plate through the reset of the hook post, eliminating the need for workers to carry it down, which can reduce the physical consumption of workers. However, this solution also does not elaborate on which method is used to machine the green blank plate in the machining system.

[0005] In the above-mentioned prior art, the problem of how to make the green blank plate reach the standard size has not been solved, and the product quality cannot be guaranteed. There is an urgent need for an automated continuous trimming device for non-metallic sound barriers that can simultaneously trim the convex part, concave part, and top surface of the sound barrier green blank plate without pausing. Through the smooth connection between processes, it changes the processing method of a single machine tool in the existing sound barrier machining process, reduces labor costs, improves production efficiency and product quality, and creates favorable conditions for subsequent assembly after forming the standard size. Summary of the Invention

Detailed implementation mode

[0047] In order to enable those skilled in the art to better understand the solution of this application, the following will combine the attached Figure 1 - 27 to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0048] [[ID=ID=10]]Now, an embodiment is adopted to elaborate on the above solution in detail. For the convenience of description, the Figure 3 from the right side to the left side is set as the direction of material conveyance, which is also called the horizontal direction, that is, the left side is set as the front, the right side is the rear, the up and down direction is set as the vertical direction, and the Figure 4 below is set as the left side and the above is set as the right side.

[0049] A fiber-reinforced sound barrier forming machine includes a chassis 1. On the chassis 1, there are a feeding mechanism 2 for conveying the dry blank board 6 of the sound barrier, a convex-side grinding mechanism 3 for trimming the convex part 601 of the dry blank board 6 of the sound barrier, a concave-side grinding mechanism 4 for trimming the groove part 602 of the dry blank board 6 of the sound barrier, a positioning mechanism 5 for limiting the dry blank board 6 of the sound barrier during grinding, a dust exhaust mechanism located at the convex-side grinding mechanism 3 and the concave-side grinding mechanism 4, a top trimming mechanism 7 for trimming the top surface and the groove of the top of the dry blank board 6 of the sound barrier, a pressing mechanism 8 for limiting the dry blank board 6 of the sound barrier during grinding, and a detection mechanism 9 for detecting the position of the dry blank board 6 of the sound barrier. When the dry blank board 6 is detected, the position information is transmitted to the control center, and the control center sends information to the control module at the pressing mechanism 8, and the pressing mechanism 8 makes a reaction to timely limit the dry blank board 6. At this time, the control module at the top trimming mechanism 7 makes a reaction, and the top trimming mechanism 7 trims the top surface and the groove of the top of the dry blank board 6. The setting of the positioning mechanism 5 and the pressing mechanism 8 avoids the occurrence of deviation during the grinding process and ensures the product quality. If the dry blank board 6 is not well limited, it is easy to be damaged or ground obliquely during grinding, affecting the product quality and work efficiency; multiple pressing mechanisms 8 are arranged at intervals along the length direction of the chassis 1, and each top trimming mechanism 7 is located between two adjacent pressing mechanisms 8 to ensure that during the trimming process, there is always a pressing mechanism 8 limiting the dry blank board 6 to avoid the occurrence of deviation during the grinding process and ensure the product quality.

[0050] Refer to Figure 18 、 Figure 19 and Figure 20As shown in the figure, the above-mentioned feeding mechanism 2 includes two support frames 201 that are opposite to each other and spaced apart on the chassis 1. Between the two support frames 201, a conveying roller 202 driven by a power device to rotate is installed. The number of conveying rollers 202 is set to be multiple, and the multiple conveying rollers 202 are spaced apart along the conveying direction of the material. A conveyor belt for carrying the green blank board 6 is wound around the multiple conveying rollers 202. At the tops of the two support frames 201, a first material guiding seat 203 and a second material guiding seat 204 are respectively arranged. On the opposite side surfaces of the first material guiding seat 203 and the second material guiding seat 204, a first guiding wheel 2031 and a limiting plate 2041 are respectively installed to guide and limit the green blank board 6, so that it can run smoothly in the horizontal direction and avoid deviation during the conveying process. Further, on the opposite side surfaces of the first material guiding seat 203 and the second material guiding seat 204, a first wheel group and a limiting group are respectively installed. That is, the first wheel group includes multiple first mounting bases that are spaced apart and have aligned ends and are installed on the side surface of the first material guiding seat 203. The distances between adjacent two first mounting bases are all equal, that is, the multiple first mounting bases are arranged at equal distances. On both sides of each first mounting base, a first support plate is arranged. The two first support plates are inclined from the rear to the front to conform to the conveying direction of the green blank board 6, reduce the force, and ensure the structural stability. A first mounting hole is opened on each of the two first support plates, and the two first mounting holes are coaxially arranged. A first rotating shaft is inserted into the two first mounting holes, and the above-mentioned first guiding wheel 2031 is sleeved on the first rotating shaft. Thus, the multiple first guiding wheels 2031 are spaced apart along the material conveying direction, and the distance between every two adjacent first guiding wheels 2031 is equal, and they are all correspondingly arranged with the convex part 601 of the green blank board 6 to ensure the guiding effect on the green blank board 6 and help the conveying of the green blank board 6. The limiting group includes multiple limiting plates 2041 that are spaced apart and installed on the side surface of the second material guiding seat 204. The multiple limiting plates 2041 are spaced apart and aligned along the material conveying direction and are correspondingly arranged with the groove part 602 of the green blank board 6 to ensure the limiting effect on the green blank board 6 and avoid deviation during the conveying process, which may affect the subsequent trimming. The area of the limiting plate 2041 close to the top surface of the green blank board 6 is smaller than the area of the bottom surface far from the green blank board 6, reducing the contact area with the green blank board 6 to reduce the conveying resistance. The setting of the bottom surface being larger than the top surface makes the connection with the second material guiding seat 204 more stable. When feeding, the green blank board 6 is located between the first wheel group and the limiting group. The multiple first guiding wheels 2031 all abut against the convex part 601 of the green blank board 6, and the groove part 602 of the green blank board 6 abuts against the multiple limiting plates 2041. During the process of conveying the green blank board 6, the first guiding wheels 2031 and the limiting plates 2041 play the roles of guiding and limiting, so that the green blank board 6 always moves forward horizontally along with the conveyor belt, avoiding the deviation of the green blank board 6 during the conveying process, which may affect the subsequent trimming effect, ensuring smooth feeding, and ensuring that the green blank board 6 does not deviate during feeding.

[0051] Refer toFigure 18 , Figure 19 and Figure 20 As shown in Figure 18 , Figure 19 and Figure 20 , the feeding mechanism 2 further includes a plurality of columns 205 mounted on the chassis 1. A pressing plate 206 driven by a feeding driving mechanism to move vertically is mounted on each column 205. A plurality of pressing wheels 2061 pressing on the top surface of the green blank board 6 are mounted at the bottom of the pressing plate 206. The plurality of pressing wheels 2061 are spaced at equal distances along the length direction of the pressing plate 206 to ensure the stability of the pressing plate 206 during operation and can be evenly pressed on the green blank board 6, so that the green blank board 6 is uniformly stressed and the conveying is stable. Further, the number of columns 205 is set to four. The columns 205 on the same side are set as a group, namely the first column group and the second column group. The four columns 205 are respectively set as the first column and the second column on the same side, and the third column and the fourth column on the same side. The feeding driving mechanism is set to four, which are respectively the first feeding driving mechanism, the second feeding driving mechanism, the third feeding driving mechanism, and the fourth feeding driving mechanism mounted on the first column, the second column, the third column, and the fourth column. The first feeding driving mechanism, the second feeding driving mechanism, the third feeding driving mechanism, and the fourth feeding driving mechanism can all adopt motors. The pressing plate 206 is set as the first pressing plate and the second pressing plate. The above-mentioned first column group includes the first column and the second column, and the second column group includes the third column and the fourth column. The first column group and the second column group are respectively arranged on both sides of the corresponding green blank board 6. The output ends of the first feeding driving mechanism on the first column and the second feeding driving mechanism on the second column are both connected to the rear end and the front end of the first pressing plate and are symmetrically arranged with respect to the center of the first pressing plate, ensuring the stability of the first pressing plate. The output ends of the third feeding driving mechanism on the third column and the fourth feeding driving mechanism on the fourth column are both connected to the rear end and the front end of the second pressing plate and are symmetrically arranged with respect to the center of the second pressing plate, ensuring the stability of the second pressing plate. A plurality of the above-mentioned pressing wheels 2061 capable of pressing on the corresponding green blank board 6 are provided at the bottoms of the first pressing plate and the second pressing plate. The first pressing plate and the second pressing plate are symmetrically arranged, that is, symmetrically arranged with respect to the center line of the first guide seat 203 and the second guide seat 204, ensuring that they are pressed on both sides of the top of the green blank board 6 to make its conveying stable, combined with Figure 18 - 20 the structural schematic diagrams of steps a, b, and c of the feeding mechanism in Figure 18 - 20 and the first feeding driving mechanism, the second feeding driving mechanism, the third feeding driving mechanism, and the fourth feeding driving mechanism are simultaneously controlled by a control system to ensure that the moving distances in the vertical direction are equal, ensuring that the green blank board 6 remains horizontal and avoiding the situation of not being on the same horizontal line due to excessive force on one side, improving the subsequent trimming quality.

[0052] The above-mentioned positioning mechanism 5 includes a plurality of positioning posts 501 installed on the chassis 1.

A plurality of trimming support seats 702 capable of moving in the vertical direction driven by a trimming driving mechanism are arranged between each pair of trimming brackets 701. A trimming roller 703 driven to rotate by a roller power mechanism is installed on each trimming support seat 702. A plurality of hob cutters 7031 are arranged at intervals on the trimming roller 703 for grinding the grooves on the top of the green blank board 6. Among them, each trimming support seat 702 is arranged at the center of each group of trimming brackets 701 to ensure that the trimming roller 703 thereon is located at the center, which is beneficial to the grinding of the green blank board 6 and avoids missing areas during grinding; two trimming support seats 702 are provided on each group of trimming brackets 701, and the two trimming support seats 702 are symmetrically arranged at the front end and the rear end of the trimming bracket 701 to ensure more stability during the grinding of the hob cutter 7031; the distance between two adjacent hob cutters 7031 matches the distance between two grooves on the top of the green blank board 6, so as to facilitate the trimming of the grooves by the hob cutter 7031; the distances between the hob cutters 7031 on the multiple trimming rollers 703 and the green blank board 6 are set to be unequal and decrease sequentially along the conveying direction to trim the grooves on the top of the green blank board 6 in stages; the distance between two adjacent hob cutters 7031 on the trimming roller 703 is set as a shoulder beam 7032, and a plurality of grinding cutters 7033 are wound around the shoulder beam 7032 to facilitate the grinding of the top surface of the green blank board 6, that is, to grind the part between two grooves. The grinding cutters 7033 and the hob cutters 7031 are staggered, that is, each grinding cutter 7033 is located between two hob cutters 7031. Similarly, each hob cutter 7031 is located between two grinding cutters 7033 to facilitate the smooth discharge of debris during grinding; further, the trimming roller 703 can also be provided with multiple groups of first grinding rollers and multiple groups of second grinding rollers arranged at intervals and alternately. The first grinding rollers match the top surface of the green blank board 6 for grinding, and the second grinding rollers match the grooves on the top surface of the green blank board 6 for grinding. It can be seen that the distance between the first grinding rollers and the green blank board 6 is less than the distance between the second grinding rollers and the green blank board 6. Among them, each group of first grinding rollers and each group of second grinding rollers are set in a ring shape, that is, if there is a groove on the top plate of several blank boards 6 and three groups of grinding rollers are required, they are arranged alternately in a group of first grinding rollers, a group of second grinding rollers, and a group of first grinding rollers. When the quantity is large, it can be deduced by analogy. Each group of trimming brackets 701 is located between two adjacent pressing mechanisms 8 to ensure that during the trimming process, there is always a pressing mechanism 8 to limit the green blank board 6 to avoid deviation during grinding, ensure product quality, and avoid deviation during grinding. If the green blank board 6 is not well limited, it is easy to be ground badly or ground obliquely, affecting product quality and work efficiency.Further, the trimming brackets 701 are provided in two groups, namely the first trimming bracket and the second trimming bracket which are symmetrically arranged, and the third trimming bracket and the fourth trimming bracket which are symmetrically arranged.

The seventh sliding seat and the eighth sliding seat are symmetrically arranged horizontally, and the fourth trimming support seat is installed between the sixth sliding seat and the eighth sliding seat to ensure that the fourth trimming support seat is located in the middle, so that the trimming rollers 703 on the first trimming support seat, the second trimming support seat, the third trimming support seat and the fourth trimming support seat are all located directly above the green blank board 6, preventing offset and affecting the grinding efficiency and quality. During operation, the positions of the first trimming support seat, the second trimming support seat, the third trimming support seat and the fourth trimming support seat in the vertical direction are set in a graded manner, that is, the distances between their bottoms and the green blank board 6 gradually decrease in sequence starting from the right side, so as to perform graded trimming on the green blank board 6 to meet the requirements, improve the work efficiency and ensure the trimming quality.The above-mentioned detection mechanism 9 includes an induction rod 901 installed on the tops of two support frames 201 and capable of adjusting its position in the vertical direction through a screw rod. The induction rod 901 is located above the conveyor belt, that is, horizontally arranged above the green blank board 6. A plurality of sensors 902 are installed on the induction rod 901 at equal intervals along its length direction. The sensors 902 are connected to a controller to ensure that when the green blank board 6 runs to the position of the sensors 902, the controller can smoothly transmit the information to the control center, and then the control center transmits it to the control module in the subsequent process. Further, a first support and a second support are respectively arranged on the two support frames 201. Threaded holes are opened at the centers of the first supports. The above-mentioned screw rods are screwed into the threaded holes.

[0061] The fiber-reinforced non-metallic sound barrier in the present invention is formed by mixing materials such as cement, silica fume, fine aggregate, and organic fiber, exhausting air through a vacuum in an extruder, and extruding and forming a series of plates with different cross-sectional shapes at the die orifice under the action of high-pressure extrusion force. After one-time low-temperature steam curing, it is then cured by high-temperature and high-pressure steam. The ECP board has a high density and is suitable for the construction of non-metallic sound barrier projects for the subgrades and bridges of high-speed railways, ordinary railways, intercity light rails, and highways. The production of the ECP sound barrier is divided into five processes. The first process: mixing and stirring, mixing raw materials such as cement, fiber, and silica according to the ratio. The second process: vacuum extrusion, pressurizing the initial slurry in a vacuum state to extract the air in the materials to increase the density of the board, and extruding through a specific mold, with different molds producing different board types. The third process: curing in the kiln, sending the extruded and formed board to the curing kiln for the first curing. The fourth process: cutting and processing, processing after leaving the kiln, and performing cutting and grinding and polishing treatments according to the ordered dimensions. The fifth process: high-temperature curing, putting it into a high-temperature and high-pressure kiln for secondary curing to cause a chemical reaction of the cement and further increase the strength and toughness of the board. During the production of the fiber-reinforced non-metallic sound barrier, that is, the grinding and polishing according to the set dimensions in the above-mentioned fourth process.

[0062] During operation, first, according to the requirements of different models, set the positions of the first positioning pressing plate and the third positioning pressing plate in the vertical direction in the positioning mechanism 5, and set the positions of the second positioning pressing plate and the fourth positioning pressing plate in the vertical direction. The power device operates, and the green blank plate 6 is located on the conveyor belt between the first wheel set and the limiting group, and runs forward along the conveying direction from the rear with the conveyor belt. The groove portion 602 of the green blank plate 6 abuts against a plurality of limiting plates 2041, and a plurality of first guide wheels 2031 all abut against the convex portion 601 of the green blank plate 6, limiting the green blank plate 6 in the left-right direction to prevent offset. During the process of conveying the green blank plate 6, the first guide wheels 2031 and the limiting plates 2041 play a role in guiding and limiting, so that the green blank plate 6 always advances horizontally with the conveyor belt, avoiding offset of the green blank plate 6 during the conveying process and affecting the subsequent trimming effect, ensuring smooth feeding, and ensuring that the green blank plate 6 does not deviate during feeding; at the same time, adjust the position of the trimming support base 702 in the vertical direction through the trimming drive mechanism as needed, so that the distance between the trimming roller 703 on the trimming support base 702 and the green blank plate 6 reaches the required value, so as to facilitate the subsequent hob 7031 and trimming cutter 7033 to grind the top surface and groove of the green blank plate 6 and ensure the trimming quality. Then, when the green blank plate 6 runs between the convex side grinding mechanism 3 and the concave side grinding mechanism 4, adjust the first convex side lead screw, the second convex side lead screw, the third convex side lead screw, and the fourth convex side lead screw to adjust the positions of the first convex side trimming cutter, the second convex side trimming cutter, the third convex side trimming cutter, and the fourth convex side trimming cutter and the convex portion 601 of the green blank plate 6, so as to facilitate the grinding of the outer end surface of the convex portion 601 of the green blank plate 6 to meet the use requirements; adjust the first concave side lead screw, the second concave side lead screw, the third concave side lead screw, and the fourth concave side lead screw to adjust the positions of the first concave side trimming cutter, the second concave side trimming cutter, the third concave side trimming cutter, and the fourth concave side trimming cutter and the groove portion 602 of the green blank plate 6, so as to facilitate the grinding of the outer end surface of the groove portion 602 of the green blank plate 6 to meet the use requirements. During the above process, the convex side grinding mechanism 3 and the concave side grinding mechanism 4 both work simultaneously, and both sides of the green blank plate 6 are trimmed simultaneously, which is conducive to the smooth conveyance of the green blank plate 6 along the conveying direction.Next, when the feeding mechanism 2 sends the front end of the green blank board 6 to the positioning mechanism 5, the pressing wheel 2061 on the pressing plate 206 of the feeding mechanism 2 still presses on the rear end of the green blank board 6; during this process, the convex side grinding mechanism 3 and the concave side grinding mechanism 4 simultaneously trim the convex portion 601 and the groove portion 602 of the green blank board 6; by adjusting the first convex side tilting lead screw, the first convex side tilting seat 305 is moved closer to or farther away from the green blank board 6, so that the first convex side tilting grinding tool 3051 driven by the fifth convex side driving mechanism is moved closer to or farther away from the green blank board 6. When the first convex side tilting grinding tool 3051 and the convex portion 601 of the green blank board 6 are in the set position, the lower edge of the end of the convex portion 601 of the green blank board 6 is ground to meet the requirements; by adjusting the second convex side tilting lead screw, the position of the convex side support frame 306 in the left-right direction is adjusted, and by adjusting the third convex side tilting lead screw, the position of the sixth convex side driving mechanism in the vertical direction is adjusted. After the second convex side tilting grinding tool 3061 and the convex portion 601 of the green blank board 6 reach the set position, the upper edge of the end of the convex portion 601 of the green blank board 6 is ground to meet the requirements; the first concave side tilting grinding tool 4051 grinds the lower edge of the groove portion 602 of the green blank board 6, and the second concave side tilting grinding tool 4061 grinds the upper edge of the groove portion 602 of the green blank board 6; the fifth concave side grinding tool 4071 grinds the upper groove surface of the groove portion 602 on the green blank board 6, and the sixth concave side grinding tool 4072 grinds the lower groove surface of the groove portion 602 on the green blank board 6; to ensure that the groove portion 602 of the green blank board 6 is comprehensively ground quickly to meet the required standards, ensuring product quality, improving production efficiency, and facilitating subsequent installation. Finally, when the green blank board 6 runs to the pressing mechanism 8, the pressing mechanism 8 limits the green blank board 6 to prevent it from running off track. Then, the green blank board 6 continues to run. When it runs to the trimming roller 703, the roller power mechanism drives the trimming roller 703 to rotate, and the hob 7031 and the grinding tool 7033 on it quickly grind the top surface and the groove of the green blank board 6.
