Description
Technical Field
[0001] The present invention relates to the technical field of concrete specimen production, and particularly to a multifunctional integrated automatic fiber concrete forming machine and its usage method. Background Art
[0002] Concrete specimens are the key basis for evaluating the mechanical properties and durability of concrete. Their quality has an important impact on the safety and reliability of engineering structures. Especially in the field of fiber concrete, the uniformity of specimens and the degree of fiber dispersion play a crucial role in performance test results. Therefore, preparing concrete specimens that meet the specifications and have high consistency is of extremely important significance for material research, engineering quality control, and industry standard formulation. However, when laboratories currently prepare fiber concrete or ordinary concrete specimens, the following problems are mainly faced: 1. Traditional methods for preparing concrete specimens usually rely on manual operation, which is not only inefficient, but also lacks precision, and at the same time increases the labor intensity.
[0003] 2. Concrete raw materials in the laboratory are relatively dispersed. Due to differences in properties such as water content between different batches of materials, it is difficult to ensure the consistency of specimens when making a large number of specimens.
[0004] 3. When preparing concrete specimens in the laboratory, the weighing of raw materials is mainly completed manually, and the error in the weighing process is relatively large. Moreover, during the process of putting raw materials into the mixer, raw material loss is likely to occur, thus affecting the performance of concrete.
[0005] 4. During the preparation process of fiber concrete, the dispersion of fibers has a significant impact on the performance of concrete. If the fibers cannot be evenly dispersed, it is easy to form agglomerates, resulting in uneven internal structure of concrete, and thus reducing its crack resistance, toughness, and durability. Currently, the feeding and dispersion of fibers in the laboratory mostly adopt manual methods, which not only make it difficult to ensure the uniform distribution of fibers, but also increase the complexity of operation and time cost.
[0006] 5. The cleaning work of the concrete mixer takes a large amount of time and water resources. If the cleaning is not thorough, the concrete remaining on the mixing blades or the inner wall of the mixing barrel may solidify, resulting in a decline in the mixing performance of the mixer.

[0018] A method for using a multifunctional integrated fiber concrete automatic molding machine specifically includes the following steps: S1: Automatic feeding; solid materials and fibers are put in through a screw feeder and a fiber dispersion unit, liquid admixtures and water are put in through an admixture feeding unit and a cleaning and water supply unit, and the feeding operation is controlled in real time through an automation control system; S11: Feeding by the screw feeder; The automation control system controls the screw feeder shaft driving motor to rotate at a constant speed. The materials in the storage tank are transported through the hopper of the mixing tank and into the mixing tank, and the fibers are transported from the storage tank to the fiber dispersion unit; different types of materials are put in sequentially, and the weight sensor of the mixing tank electrically connected to the automation control system measures the weight in the mixing tank in real time. When the weight reaches the set parameters, the automation control system controls the screw feeder shaft driving motor to stop working, and the feeding is completed; S12: Fiber dispersion; The fibers are conveyed from the storage tank to the fiber dispersion unit by a spiral feeder, preliminarily separated through a separation grid, and then fall onto the dispersion comb teeth. The automatic control system controls the dispersion shaft drive motor to drive the dispersion shaft to rotate. The dispersion comb teeth on the dispersion shaft disperse the bundled fibers. The dispersed fibers enter the mixing tank through the mixing tank hopper. The mixing tank weight sensor electrically connected to the automatic control system measures the weight inside the mixing tank in real time. When the weight reaches the set parameter, the automatic control system controls the spiral feed shaft drive motor and the dispersion shaft drive motor to stop working, and the fiber feeding is completed; S13: Add liquid admixture and water; The automatic control system controls the liquid storage tank valve controller to open the liquid storage tank valve. The liquid admixture enters the mixing tank through the mixing tank hopper. The mixing tank weight sensor electrically connected to the automatic control system measures the weight inside the mixing tank in real time. When the weight reaches the set parameter, the automatic control system controls the liquid storage tank valve controller to close the liquid storage tank valve and stop adding the liquid admixture; The automatic control system controls the pressure pump to work at low power, and the water enters the mixing tank through the spray arm. The mixing tank weight sensor electrically connected to the automatic control system measures the weight inside the mixing tank in real time. When the weight reaches the set parameter, the automatic control system controls the pressure pump to stop working and stop adding water; S2: Automatic mixing. After all the materials are added, the automatic control system controls the mixing tank hopper control valve to close the mixing tank hopper. The automatic control system controls the mixing shaft drive motor to work, and the mixing blades agitate the materials inside the mixing tank for mixing. When the set time is reached, the automatic control system controls the mixing shaft drive motor to stop working and the mixing stops; S3: Mold leveling; S31: Automatic leveling detection by lidar. When the discharge door of the mixing tank is closed, the automatic control system controls the lidar to scan the four corner points of the lower forming mold; If the lidar scans the four corner points of the forming mold, step S32 is executed, otherwise the position of the forming mold is adjusted until the lidar scans the four corner points of the forming mold; S32: Leveling. The automatic control system calculates the horizontal inclination angle of the plane formed by the four corner points of the forming mold based on the distances scanned by the lidar to the four corner points of the forming mold, and calculates the height adjustment amounts of the four leveling screws according to the horizontal inclination angle; S4: Pouring; During pouring, each mold cavity of the forming mold is filled in sequence. The automatic control system controls the motor of the discharge door of the mixing tank to drive the discharge door of the mixing tank to open outward. The concrete in the mixing tank falls into the feeding trough through the discharge door of the mixing tank and then enters the forming mold through the feeding trough. During this process, the automatic control system controls the eccentric vibrator to work, and the lidar measures the height of the upper surface of the concrete in the forming mold in real time. When the upper surface of the filled concrete reaches the plane formed by the four corner points of the initially scanned forming mold, the automatic control system controls the motor of the discharge door of the mixing tank to drive the discharge door of the mixing tank to close, stops pouring, and the eccentric vibrator stops working. The automatic leveling forming system moves away through the guide rail of the leveling system bottom plate; S5: Self-cleaning; S51: Self-cleaning of the mixing device. The automatic control system controls the pressure pump to work at full power, and the high-pressure water drives the spray arm to rotate.

If the distances to several points are all the same as the distances measured when the mixing tank is empty without adding materials, it means the cleaning is completed. If the distance to a certain point is less than the distance measured when the mixing tank is empty without adding materials, it means the cleaning is not thorough, and steps S51 - S52 are re-executed until the cleaning is completed; S6: Demolding; The automatic control system controls the motor of the rotating platform rotating shaft to work, rotates the rotating shaft of the rotating platform, horizontally flips the rotating platform plate, and the compressed air will push out the solidified test block through the mold check valve. Subsequently, the rotating platform plate resets to complete demolding.
[0019] Preferably, step S32 specifically includes the following steps: The distances measured by the lidar from the four corner points A, B, C, D of the forming mold are dA, dB, dC, dD respectively. The position of the lidar is the origin O, and the height is set as h. is the pitch angle from the lidar to the corner point, is the horizontal azimuth angle from the lidar to the corner point. Then the three-dimensional coordinates (xi, yi, zi) of each corner point, i = A, B, C, D, are expressed as: ; ; ; Select any three points, such as A, B, and C, to calculate the plane equation. First, calculate two vectors: ; ; Then, find the normal vector : ; ; ; The plane equation is expressed as: ; Judge whether the plane is horizontal. The necessary and sufficient condition for the plane to be horizontal is that the normal vector is in the vertical direction, that is and . Considering the existence of real errors, if and , is the preset tolerance, then the plane is horizontal. If it is not horizontal, correct the heights of the four corner points; The correction amount for each corner point is the difference between the current height and the target horizontal plane. Calculate the average height of the current plane as , the correction displacement , a positive value indicates that it needs to be raised, and a negative value indicates that it needs to be lowered. Obtain the height correction values , , , , and adjust the height of the leveling screw nut according to the height correction value; Finally, set that after the leveling screw rotates n circles, the moving distance of the leveling screw nut is unit 1. Thus, the automatic control system calculates the number of circles N that the leveling screw needs to rotate from the distances that the four leveling screw nuts need to move in the vertical direction, that is, controls the leveling motor to drive the leveling screw to rotate N circles.

The dispersed fibers enter the mixing tank 21 through the mixing tank hopper 214, and the mixing tank weight sensor 213 electrically connected to the automated control system 4 measures the weight in the mixing tank 21 in real time. When the weight reaches the set parameter, the automated control system 4 controls the screw feed shaft drive motor 1123 and the dispersion shaft drive motor 1135 to stop working, and the fiber feeding is completed.
[0055] S13: Adding liquid admixtures and water; The automated control system 4 controls the liquid storage tank valve controller 1241 to open the liquid storage tank valve 124. The liquid admixture enters the mixing tank 21 through the mixing tank hopper 214. The mixing tank weight sensor 213 electrically connected to the automated control system 4 measures the weight inside the mixing tank 21 in real time. When the weight reaches the set parameter, the automated control system 4 controls the liquid storage tank valve controller 1241 to close the liquid storage tank valve 124 and stop adding the liquid admixture. The automated control system 4 controls the pressure pump 132 to operate at low power. Water enters the mixing tank 21 through the spray arm 134. The mixing tank weight sensor 213 electrically connected to the automated control system 4 measures the weight inside the mixing tank 21 in real time. When the weight reaches the set parameter, the automated control system 4 controls the pressure pump 132 to stop working and stop adding water.
[0056] S2: Automatic mixing. After all the materials are added, the automated control system 4 controls the mixing tank hopper control valve 2141 to close the mixing tank hopper 214. The automated control system 4 controls the mixing shaft drive motor 224 to work. The mixing blades 222 agitate the materials inside the mixing tank 21 for mixing. When the set time is reached, the automated control system 4 controls the mixing shaft drive motor 224 to stop working and the mixing stops.
[0057] S3: Mold leveling; S31: Automatic leveling detection by the lidar 2151. When the mixing tank discharge door 2152 is closed, the automated control system 4 controls the lidar 2151 to scan the four corner points of the lower forming mold 321. If the lidar 2151 scans the four corner points of the forming mold 321, then step S32 is executed. Otherwise, the position of the forming mold 321 is adjusted until the lidar 2151 scans the four corner points of the forming mold 321.
[0058] S32: Leveling. The automated control system 4 calculates the horizontal inclination angle of the plane formed by the four corner points of the four forming molds 321 based on the distances scanned by the lidar 2151 to the four corner points of the forming mold 321, and calculates the height adjustment amounts of the four leveling screws 3132 based on the horizontal inclination angle.
[0059] Step S32 specifically includes the following steps: The distances measured by the lidar 2151 to the four corner points A, B, C, D of the forming mold 321 are dA, dB, dC, dD respectively. The position of the lidar 2151 is the origin O, and the height is set as h. is the pitch angle from the lidar 2151 to the corner point. is the horizontal azimuth angle from the lidar 2151 to the corner point. Then the three-dimensional coordinates (xi, yi, zi) of each corner point, i = A, B, C, D, can be calculated by the following formula: ; ; ; Calculate the plane equation for any three points such as A, B, and C. First, calculate two vectors: ; ; Then find the normal vector : ; ; ; The plane equation is expressed as: ; Then determine whether the plane is horizontal. The necessary and sufficient condition for the plane to be horizontal is that the normal vector is in the vertical direction, that is and . Considering the existence of real errors, if and , is the tolerance, such as 0.001, then the plane is horizontal. If it is not horizontal, correct the heights of the four corner points.
[0060] The correction amount for each corner point is the difference between the current height and the target horizontal plane. Calculate the average height of the current plane as , the correction displacement , a positive value indicates that it needs to be raised, and a negative value indicates that it needs to be lowered, to obtain the height correction values of the four corner points, that is, the height correction values of the leveling screw nuts 3131 , , , .
[0061] Finally, set that after the leveling screw 3132 rotates n circles, the moving distance of the leveling screw nut 3131 is unit 1. Thus, the automated control system 4 calculates the number of circles N that the leveling screw 3132 needs to rotate from the distances that the four leveling screw nuts 3131 need to move in the vertical direction, that is, controls the leveling motor 3133 to drive the leveling screw 3132 to rotate N circles.
[0062] S4: Pouring; During pouring, each mold cavity of the forming mold 321 is filled in sequence. The automatic control system 4 controls the stirring tank discharge door control motor 2153 to drive the stirring tank discharge door 2152 to open outward. The concrete in the stirring tank falls through the stirring tank discharge door 2152 into the feeding trough 25 and then enters the forming mold 321 through the feeding trough 25. During this process, the automatic control system 4 controls the eccentric vibrator 322 to work, and the lidar 2151 measures the height of the upper surface of the concrete in the forming mold 321 in real time. When the upper surface of the filled concrete reaches the plane formed by the four corner points of the initially scanned forming mold 321, the automatic control system 4 controls the stirring tank discharge door control motor 2153 to drive the stirring tank discharge door 2152 to close, stops pouring, the eccentric vibrator 322 stops working, and the automatic leveling forming system 3 moves away through the leveling system bottom plate guide rail 3111.
[0063] S5: Self-cleaning; S51: Self-cleaning of the mixing device. The automatic control system 4 controls the pressure pump 132 to work at full power. The high-pressure water drives the spray arm 134 to rotate, and the water flow sprayed by the spray arm 134 flushes the stirring tank 21, the stirring blades 222, and the stirring scraper 223. The automatic control system 4 controls the stirring shaft drive motor 224 to work, and the stirring blades 222 rotate around the stirring shaft 221.
[0064] S52: Detect the cleanliness by the lidar 2151. The automatic control system 4 controls the pressure pump 132 and the stirring shaft drive motor 224 to stop working, controls the stirring tank discharge door control motor 2153 to drive the stirring tank discharge door 2152 to open outward, discharges the sewage, controls the stirring tank discharge door control motor 2153 to drive the stirring tank discharge door 2152 to rotate into the stirring tank 21, and the lidar 2151 scans several points inside the stirring tank housing 212. If the distances to several points are all the same as the distances measured when it is empty without adding materials, it means the cleaning is completed. If the distance to a certain point is less than the distance measured when it is empty without adding materials, it means the cleaning is not thorough, and steps S51 - S52 are executed again until the cleaning is completed.
[0065] S6: Demoulding; The automatic control system 4 controls the rotating platform rotating shaft drive motor 3123 to work, rotates the rotating platform rotating shaft 3122, and the rotating platform plate 3121 is horizontally flipped.
