[0002] Glass fiber cement is a high-quality cement used to make glass fiber reinforced cement products or concrete. It not only improves the alkali resistance of glass fiber, but also reduces the erosion of cement on glass fiber. It is a new type of cement in the 21st century that has multiple properties such as early strength, high strength, low alkali, impermeability, corrosion resistance, freeze-thaw resistance, carbonization resistance, micro-expansion and shrinkage compensation, negative temperature construction, coloring and durability, and can inhibit alkali-aggregate reaction.

[0003] In the prior art, when preparing cement precast components, the mixed concrete raw materials are poured into the precast component mold, and then the concrete raw materials in the precast component mold are compacted by a vibrator, and the solidified precast component is removed from the mold after it solidifies. In order to improve production efficiency, multiple slots are set on a single precast component mold, as shown in the attached manual. Figure 1 As shown, in order to mass-produce prefabricated components, in order to facilitate the separation of the solidified prefabricated components from the mold, a water-based release agent is applied in advance to the inner wall of the prefabricated component mold, and a vibration platform is used to drive the inverted prefabricated component mold to vibrate and separate the prefabricated components. In the actual operation process, due to the problem of uniformity in applying the water-based release agent and the problem of large-particle stone wearing the water-based release agent on the inner wall of the prefabricated component mold when pouring concrete raw materials, some prefabricated components cannot be smoothly separated from the prefabricated component mold. At this time, the power of the vibration platform is increased to drive the entire prefabricated component mold to vibrate, which will cause damage to some prefabricated components and affect the qualified rate of the produced prefabricated components. Application Contents

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 2-Figure 8 A glass fiber reinforced cement prefabricated component is shown, which is made of the following raw materials in parts by weight: 30-50 parts of cement, 30-40 parts of quartz sand, 2-3 parts of chopped alkali-resistant glass fibers, 1-3 parts of viscosity enhancer, 2-4 parts of auxiliary agent, and 10-15 parts of mixing water; The preparation method comprises the following steps: S1. Raw material mixing: prepare the raw materials in specified weight parts, add cement and quartz sand into the mixer and mix them evenly, then dissolve the auxiliary agent and viscosity enhancer into the mixing water, then disperse the short chopped alkali-resistant glass fiber into the mixing water, and add the mixing water into the mixer, stirring while adding until it is uniform; S2, pouring the raw materials into the mold: brushing the inner wall surface of the prefabricated component mold 1 with a water-based release agent, then pouring the mixed raw materials obtained in step S1 into the prefabricated component mold 1, and tamping the mixed raw materials in the prefabricated component mold 1 by a vibrator; S3, solidification demoulding: the prefabricated component mold 1 into which the mixed raw materials are poured is left to stand for 10 to 24 hours to solidify, then it is turned upside down and transferred to a low-damage demoulding device for vibration demoulding; S4, component discharging: separating the prefabricated component mold 1 from the prefabricated component, and transporting the prefabricated component to a designated location for storage; See also Figure 3-Figure 9 The low-damage demoulding equipment includes: a vibration conveying mechanism, a directional demoulding mechanism and an intelligent directional demoulding device 3; the vibration conveying mechanism includes a conveying table 2, a conveying roller installed on the conveying table 2 and a vibration platform. The prefabricated component mold 1 with the solidified prefabricated component is inverted on the conveying mechanism, and is moved to the vibration platform through the conveying roller on the conveying mechanism. The vibration of the vibration platform drives the prefabricated component mold 1 to shake and demould.

[0020] It is worth mentioning that the directional demolding mechanism includes an adjustment plate 5 arranged above the vibration platform, a plurality of adsorption air pipes 10 vertically plugged with the adjustment plate 5, a suction cup 12 installed at the bottom of the adsorption air pipe 10, and a conduction rod 16. The adsorption air pipe 10 corresponds to the slot on the prefabricated component mold 1. The plurality of adsorption air pipes 10 are connected in series through a cluster air pipe 11. The input end of the cluster air pipe 11 is externally connected to a negative pressure air pump. Each adsorption air pipe 10 is connected to a conduction rod 16. A telescopic cylinder 6 connected to the adjustment plate 5 at the output end is installed on the conveying platform 2. The outer ring of the adsorption air pipe 10 is fixedly connected to the bottom The seat 18 is provided with a return spring 17 between the base 18 and the adjusting plate 5. The adjusting plate 5 is provided with a distance sensor 19 corresponding to the base 18. The adjusting plate 5 is controlled to move up and down by the extension and contraction of the telescopic cylinder 6, thereby driving the adsorption air pipe 10 and the suction cup 12 to move away from the back of the prefabricated component mold 1 or close to the back of the prefabricated component mold 1. When the adsorption air pipe 10 and the suction cup 12 are close to and fit the back of the slot of the prefabricated component mold 1, the negative pressure air pump can generate negative pressure on the cluster air pipe 11 so that the suction cup 12 is adsorbed on the back of the slot of the prefabricated component mold 1. At this time, the adsorption air pipe 10 can be driven upward by lifting the adjustment plate 5, and the prefabricated component mold 1 can be driven upward, because each slot of the prefabricated component mold 1 contains a prefabricated component; at this time, when the prefabricated component corresponding to the position adsorbed by the suction cup 12 is separated from the slot, the adjustment plate 5 can drive the corresponding adsorption air pipe 10 to move up a certain distance; when the prefabricated component corresponding to the position adsorbed by the suction cup 12 is not completely separated from the slot, due to the gravity of the prefabricated component, the adsorption air pipe 10 moves up a small distance or remains in place. At this time, the misalignment distance between the adsorption air pipe 10 and the adjustment plate 5 can be judged. It is possible to determine whether the prefabricated component in the slot of the prefabricated component mold 1 corresponding to the adsorption air pipe 10 is completely detached, and by individually controlling the vibration of the conduction rod 16 corresponding to the adsorption air pipe 10, the vibration is transmitted to the corresponding slot of the prefabricated component mold 1, and the corresponding prefabricated component is detached from the prefabricated component mold 1 by individual directional vibration, thereby improving the demoulding efficiency. In traditional operations, it is usually necessary to increase the vibration power of the vibration platform for normal demoulding, which can easily lead to damage to the prefabricated component due to excessive vibration power. Therefore, the technical solution of the present application can further increase the qualified rate of prefabricated components produced.

[0021] In this embodiment, a demoulding detection module and a reminder module 4 are provided on the intelligent directional demoulding device 3. The demoulding detection module is electrically connected to the reminder module 4, the telescopic cylinder 6, the distance sensor 19 and the negative pressure air pump respectively. A proximity sensor 20 for detecting the position of the prefabricated component mold 1 is installed on one side of the conveying platform 2. The proximity sensor 20 is electrically connected to the demoulding detection module. When the inverted prefabricated component mold 1 moves to the vibration platform along with the conveying roller on the conveying platform 2, the vibration platform drives the prefabricated component mold 1 to vibrate for demoulding. The proximity sensor 20 detects that the prefabricated component mold 1 moves to the vibration platform and sends the detected position information to the demoulding detection module. After receiving the position information, the demoulding detection module controls the telescopic cylinder 6 to move to the vibration platform. The cylinder 6 contracts, and at this time the adjusting plate 5 drives the adsorption air pipe 10 and the suction cup 12 to gradually approach the prefabricated component mold 1. When the suction cup 12 is attached to the prefabricated component mold 1, the distance sensor 19 detects that the distance between it and the base 18 is shortened, and transmits the detected distance data to the demoulding detection module. At this time, the demoulding detection module determines that the suction cup 12 has contacted the back of the prefabricated component mold 1, and the demoulding detection module controls the negative pressure air pump to work. The negative pressure air pump generates negative pressure to make the suction cup 12 fit and adsorb on the back of the prefabricated component mold 1. At the same time, the demoulding detection module controls the telescopic cylinder 6 to extend, and the telescopic cylinder 6 controls the adjusting plate 5 and the adsorption air pipe 10 to move up; at this time, the distance sensor 19 corresponding to the base 18 on the adsorption air pipe 10 will detect The measured distance data is transmitted to the demoulding detection module in real time; the demoulding detection module compares the received distance data with the preset standard distance data (the demoulding detection module is preset with the standard distance data between the base 18 on the corresponding adsorption air pipe 10 and the reset spring 17 when the prefabricated component is separated from the corresponding prefabricated component mold 1 slot). When the distance data is less than or equal to the standard distance data, the demoulding detection module determines that the prefabricated component mold 1 slot corresponding to the reset spring 17 is separated from the prefabricated component; when the distance data is greater than the standard distance data, the demoulding detection module determines that the prefabricated component mold 1 slot corresponding to the reset spring 17 is not separated from the prefabricated component, and the demoulding detection module sends this reset spring 17 to the reminder module 4. The slot of the prefabricated component mold 1 corresponding to the spring 17 is not separated from the prefabricated component. The reminder module 4 sends a corresponding sound and light reminder. At this time, the slot of the prefabricated component mold 1 that has not been separated can be demoulded by separate directional vibration by separately vibrating the conduction rod 16 corresponding to the reset spring 17; when the prefabricated components on all slots on the prefabricated component mold 1 are separated, the distance data sent by all reset springs 17 received by the demoulding detection module are less than or equal to the standard distance data, then the demoulding detection module determines that the prefabricated component is completely demoulded from the prefabricated component mold 1. At this time, the demoulding detection module controls the negative pressure air pump to stop working, and at the same time sends a complete demoulding signal to the reminder module 4, and the reminder module 4 sends a complete demoulding sound and light reminder.

[0022] In addition, one or more adsorption air pipes 10 are correspondingly provided for the slots on each prefabricated component mold 1, which can improve the stability of the negative pressure adsorption of the suction cup 12 on the adsorption air pipe 10 on the back of each slot, and can drive the slots on each prefabricated component mold 1 to move upward stably during the upward movement of the adjustment plate 5. The reset spring 17 corresponds to the slot on the prefabricated component mold 1, and the adsorption air pipe 10 is vertically slidably plugged into the adjustment plate 5. The adsorption air pipe 10 and the adjustment plate 5 are movably connected, and the reset spring 17 is driven to move upward during the upward movement of the adjustment plate 5. The reset spring 17 will drive the base 18 and the adsorption air pipe 10 to move upward. The adsorption air pipe 10 is connected to the cluster air pipe 11 through a hose, which reduces the influence of the cluster air pipe 11 on the up and down displacement of the adsorption air pipe 10 and improves the detection accuracy of the distance sensor 19.

[0023] The second implementation method: Figure 7-Figure 8 and Figure 10-12 As shown, unlike the first embodiment, the low-damage demoulding equipment also includes a directional vibration mechanism, which includes a vibration plate 8 installed above the adjustment plate 5, and a vibration motor 9 installed on the vibration plate 8. The upper end of the conduction rod 16 passes through the vibration plate 8, and the outer ring of each conduction rod 16 is sleeved with a conduction tube 15 fixed to the vibration plate 8. The top of the conduction rod 16 is fixed with a conduction head 14 matching the conduction tube 15. The vibration motor 9 drives the vibration plate 8 to vibrate when it is working. When the slot on the prefabricated component mold 1 is not separated from the prefabricated component, the adsorption air pipe 10 corresponding to the slot of the prefabricated component mold 1 moves downward relative to the position of the adjustment plate 5, and the adsorption air pipe 10 will synchronously drive the conduction rod 16 to move downward. At this time, the conduction rod 16 is located at the top The conduction head 14 is inserted into the conduction tube 15 and contacts the inner wall, so the vibration on the vibration plate 8 will be transmitted to the conduction rod 16 and then to the slot on the prefabricated component mold 1 that has not been separated from the prefabricated component, and the slot will be demoulded by directional vibration; on the contrary, when the slot on the prefabricated component mold 1 has been separated from the prefabricated component, the adjustment plate 5 will drive the adsorption air pipe 10 to move upward. At this time, the conduction head 14 located at the top of the conduction rod 16 has not entered the middle of the conduction tube 15, and the vibration generated by the vibration plate 8 will not be transmitted to the conduction rod 16; when the vibration motor 9 drives the vibration plate 8 to vibrate, the vibration is accurately and directionally transmitted to the slot that has not been separated from the prefabricated component, so as to achieve the purpose of automatic detection and automatic directional demoulding, which not only improves the demoulding efficiency but also reduces the damage of the prefabricated component.

[0024] Preferably, the diameter of the conduction head 14 is the same as the inner diameter of the conduction tube 15, so that the outer wall of the conduction head 14 is in better contact with the inner wall of the conduction tube 15. The conduction head 14 is a cylindrical structure, and the top inner ring of the conduction tube 15 is provided with an arc chamfer, so that the conduction head 14 can be better inserted into the inner cavity of the conduction tube 15. The lower end of the conduction rod 16 is placed in the middle of the adsorption air pipe 10, so that the adsorption air pipe 10 can synchronously drive the conduction rod 16 to move, and the bottom of the conduction rod 16 is level with the bottom of the suction cup 12. When the bottom suction cup 12 of the adsorption air pipe 10 contacts the back of the groove on the prefabricated component mold 1, the bottom of the conduction rod 16 and the suction cup 12 are synchronously in contact with the prefabricated component mold 1, and the vibration is transmitted to the prefabricated component mold 1 through the conduction rod 16. The adjustment plate 5 and the vibration plate 8 are connected by a connecting rod 13. The connecting rod 13 is made of elastic material to reduce the influence of the vibration of the vibration plate 8 on the adjustment plate 5, and the vibration is better transmitted to the designated part through the conduction rod 16.

[0025] It is worth mentioning that the intelligent directional demoulding device 3 is also provided with a vibration conduction module, which is electrically connected to the demoulding detection module and the vibration motor 9 respectively. When the demoulding detection module controls the extension of the telescopic cylinder 6, and the telescopic cylinder 6 controls the adjustment plate 5 and the adsorption air pipe 10 to move upward, the demoulding detection module sends a vibration signal to the vibration conduction module. After receiving the vibration signal, the vibration conduction module controls the vibration motor 9 to work, and the vibration motor 9 drives the vibration plate 8 and the conduction tube 15 to vibrate. A proximity sensor 2 7 corresponding to the adjustment plate 5 is installed on the conveying platform 2, and the proximity sensor 2 7 is electrically connected to the vibration conduction module. When the telescopic cylinder 6 controls the adjustment plate 5 When it moves up to the proximity sensor 2 7, after the directional vibration demoulding operation, the adsorption air pipe 10 and the suction cup 12 will drive the prefabricated component mold 1 to completely separate from the prefabricated component, and the proximity sensor 2 7 will detect the position information of the adjustment plate 5 and transmit it to the vibration conduction module. After receiving the position information, the vibration conduction module controls the vibration motor 9 to stop working and sends a demoulding completion signal to the demoulding detection module; after receiving the demoulding completion signal, the demoulding detection module controls the telescopic cylinder 6 to reset and the negative pressure air pump to stop working. At the same time, the demoulding detection module sends a demoulding completion alarm signal to the reminder module 4. The reminder module 4 receives the alarm signal and sends an audio-visual reminder of demoulding completion.

[0026] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
