Description

TECHNICAL FIELD

[0001] The present application relates to the prefabricated component production field, and particularly relates to a small prefabricated component automatic production device. BACKGROUND

[0002] At present, the energy-saving building material special production line usually adopts a linear layout. After the concrete is formed in the mold box, it needs to pass through independent curing stations, turnover stations and demolding stations in sequence. This segmented layout realizes automatic production, but still has certain defects in the running process. The existing typical production line usually adopts a linear process: after the concrete is formed in the mold box, the mold box is transported to the curing area through the conveying line, and then is transported to the independent turnover station for 180-degree turnover, so that the opening of the mold box faces downward, and then is transported to the independent demolding station. In the demolding station, the whole lifting vibration table or the top pneumatic hammer knocking method is usually used to separate the component from the mold box.

[0003] However, this separated layout has inherent defects: first, the mold box needs to be repeatedly positioned and transferred between the turnover, conveying and demolding independent stations, so that the production process is long, thereby affecting the production efficiency; second, in the demolding process, the independent demolding vibration is usually a whole synchronous impact, which is easy to cause damage to the internal structure of the formed concrete component and to cause defective products. Therefore, the present application provides a small prefabricated component automatic production device to solve the existing problems. SUMMARY

[0018] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] like Figures 1 to 11 As shown in the figure, an embodiment of the present invention provides a small-scale automated production device for prefabricated components, comprising: The transport mechanism 1 has a partition and also includes a mounting frame 2 located at the partition. Specifically, the transport mechanism 1 is a roller conveyor line in the prior art. The roller conveyor line has a partition for placing the mounting frame 2. The flipping mechanism 3 includes a rotating frame 301 rotatably mounted on the mounting frame 2. A driving component 302 for rotating the rotating frame 301 is mounted on the mounting frame 2. Two vertically distributed conveying assemblies 303 are installed inside the rotating frame 301. Specifically, the mounting frame 2 has two symmetrically constructed annular frame plates 11, and the rotating frame 301 is cylindrical and rotatably inserted into the two annular frame plates 11. Figure 1 As shown, the cylindrical design of the rotating frame 301 can effectively solve the space problem and avoid the phenomenon of bumping and knocking due to too many sharp corners; This application does not impose any restrictions on the rotation of the rotating frame 301; it can be any drive structure capable of satisfying the rotation of the rotating frame 301. Preferably, a drive gear 8 is rotatably mounted on the mounting frame 2, and a motor for driving the drive gear 8 is mounted on the mounting frame 2. A gear ring 9 that meshes with the drive gear 8 is mounted on the rotating frame 301. Specifically, for example... Figure 3 As shown, the number of gears on the drive gear 8 is less than the number of gears on the gear ring 9. When the motor starts and drives the drive gear 8 to rotate, because the drive gear 8 meshes with the gear ring 9, when the drive gear 8 rotates quickly, the gear ring 9 will rotate slowly relative to the rotation speed of the drive gear 8, so as to ensure the accuracy and stability of the rotating frame 301 when it rotates. The pressing mechanism 4 is installed on the rotating frame 301. The pressing mechanism 4 lifts the mold box on the lower conveying component 303 and presses it onto the upper conveying component 303. That is, after the mold box is moved into the flipping mechanism 3 by the conveying mechanism 1 (at this time, the concrete in the mold box has been formed and is located in one of the conveying components 303), the pressing mechanism 4 will lift the mold box on the conveying component 303 so that the open end of the mold box abuts against the upper conveying component 303. Then the motor drives the drive gear 8 to rotate. Because the drive gear 8 meshes with the gear ring 9, the gear ring 9 will rotate to drive the rotating frame 301 to rotate, so that the pressed mold box rotates synchronously to complete the flipping of the mold box. After the flipping is completed, the mold box will be in an upside-down state on the conveying component 303 and on the same horizontal plane as the conveying mechanism 1. The subsequent conveying component 303 can be started to transport the upside-down mold box to the conveying mechanism 1, and then transport it to the next process. Vibration component 5, mounted on the holding mechanism 4, continuously and without intervals strikes the side of the mold box away from the opening end with a wave-like motion when the holding mechanism 4 holds the mold box and rotates it between 90 and 180 degrees via the drive component 302. As the mold box rotates synchronously with the rotating frame 301, when the mold box rotates to 90 degrees (i.e., the side of the mold box is facing down), the vibration component 5 starts striking the side of the mold box away from the opening end in a wave-like motion. Compared to the existing synchronous vibration method, the vibration component 5 can continuously strike the mold box without intervals, which not only avoids damage to the concrete inside the mold box due to excessive vibration area, but also, during the vibration process, the concrete near the mold box is... The vibrating surface completes demolding first, and vibration is initiated with the mold box side facing down. This guides the demolding process to begin from this side and peel off in an orderly manner, avoiding the resistance caused by the simultaneous resistance of the adhesive forces on each surface during overall synchronous demolding. This makes the demolding process smoother and requires less external force. After the flipping mechanism 3 rotates to 180 degrees, the mold box is in an inverted state. Then, the holding mechanism 4 moves and resets, causing the mold box and the internal concrete to fall onto another conveying component 303. Demolding is completed during the process of flipping the mold box, which effectively improves production efficiency. Furthermore, the demolding is completed by the vibration component 5 using a wave-like impact, which avoids damage to the concrete caused by excessive vibration area and reduces the production of defective products.

[0020] like Figures 1 to 5As shown, in some embodiments, the holding mechanism 4 includes two drive frames 401 slidably mounted on the rotating frame 301, and two conveying components 303 located between the two drive frames 401. The vibration component 5 is two in number and is respectively mounted on the two drive frames 401. The drive frames 401 can pass through the adjacent conveying components 303 and lift the mold box opening. That is, after the mold box is conveyed to one of the conveying components 303 by the transport mechanism 1, the drive frame 401 located below can pass through the lower conveying component 303 to lift the mold box until the opening end of the mold box abuts against the upper conveying component 303. After the rotating frame 301 rotates 180 degrees to complete the flipping of the mold box, the drive frame 401 moves back to its original position, so that the mold box is in an inverted state, which is convenient for the next process to remove the mold box. Since there are two drive frames 401, the rotating frame 301 does not need to rotate back to its original position when performing the next flipping demolding, which further improves production efficiency.

[0021] like Figures 1 to 7 As shown, in some embodiments, the drive frame 401 includes multiple pressure plates 4011 slidably mounted on the rotating frame 301. Multiple sliding cylinders 4012 are constructed on the pressure plates 4011. Multiple guide rods 4013 for insertion into the sliding cylinders 4012 are fixedly mounted on the rotating frame 301. The frame also includes a connecting frame plate 4014 connected to the multiple sliding cylinders 4012. The conveying assembly 303 includes a roller conveyor mounted on the mounting frame 2. The multiple pressure plates 4011 pass through the gaps between the rollers of the roller conveyor. The multiple guide rods 4013 and the sliding cylinders 4012 serve as guides and limiters, making the multiple pressure plates 4011 more stable during movement. The roller conveyor is existing technology, using electric drive to rotate multiple rollers to transfer the mold box. Because there are gaps between the rollers, the pressure plates 4011 can pass through, without affecting the lifting of the mold box by the multiple pressure plates 4011.

[0022] like Figures 1 to 7As shown, in some embodiments, the vibration assembly 5 includes a plurality of vibration rods 501 vertically slidably inserted into the pressure plate 4011. The plurality of vibration rods 501 are linearly distributed along the length direction of the pressure plate 4011. It also includes a connecting plate 502 connecting the plurality of vibration rods 501 located on the pressure plate 4011. One end of the vibration rod 501 is normally located inside the pressure plate 4011. A connecting seat 503 is installed between the first and last pressure plates 4011. A transmission assembly 6 for driving the connecting plate 502 to reciprocate is installed on the connecting seat 503. That is, when the plurality of connecting seats 503 move toward the mold box, the plurality of pressure plates 4011 move synchronously, thereby causing the plurality of pressure plates 4011 to lift the mold box and abut against the transport assembly. When the rotating frame 301 flips... When the mold box needs to be vibrated for demolding during the process, the transmission component 6 causes multiple connecting plates 502 to move back and forth rapidly to vibrate and beat the mold box. The multiple connecting plates 502 vibrate continuously in a wave pattern when beating the mold box, thereby achieving vibration demolding. This application does not impose specific restrictions on the movement of the connecting seat 503. It can be any drive structure that can satisfy the movement of the connecting seat 503 along the axis of the sliding cylinder 4012. Specifically, two cylinders 12 are symmetrically installed on the rotating frame 301. The telescopic ends of the two cylinders 12 are respectively connected to the two connecting seats 503. It should be noted that the cylinders 12 need to be connected to external air pipes when in use. In order to avoid the air pipes getting tangled on the rotating frame 301, the rotating frame 301 rotates forward and backward within a range of 180 degrees during use to complete each flip.

[0023] like Figures 9 to 11 As shown, in some embodiments, the transmission assembly 6 includes a pivot rod 601 rotatably mounted on the connecting seat 503. One end of the pivot rod 601 is configured with a first connecting plate 602, and an eccentrically mounted column rod 603 is mounted on the first connecting plate 602. One end of the column rod 603 is configured with a second connecting plate 605 coaxial with the first connecting plate 602. A horizontally opening movable groove 604 is provided on the connecting plate 502. Multiple columns 603 are slidably tangentially positioned within the movable groove 604. A forcing member 7 acting on a nearby second connecting plate 605 is mounted on the free end of the pivot rod 601. When the pivot rod 601 rotates to a fixed angle, the forcing member 7 causes the corresponding second connecting plate 605 to rotate. A motor for driving one of the pivot rods 601 to rotate is mounted on the connecting seat 503. Preferably, the motor is mounted on one side of the connecting seat 503 and connected to the outermost second connecting plate 605 (e.g., ...). Figure 10As shown in the diagram, when the motor starts and drives the outermost second connecting plate 605 to rotate, the rotation of the second connecting plate 605 causes the column rod 603 to rotate eccentrically. Because the column rod 603 slides tangentially within the movable groove 604, as the column rod 603 rotates eccentrically, the outermost connecting plate 502 will move back and forth rapidly first. During this process, the first connecting plate 602 connected to the column rod 603 will also rotate, thereby driving the corresponding pivot rod 601 to rotate. After the pivot rod 601 rotates a certain angle, it will drive the adjacent second connecting plate 605 through the forcing member 7. The rotation causes the next second connecting plate 605 to rotate, resulting in the rapid reciprocating movement of the adjacent connecting plate 502. Because the pivot rod 601 rotates at a certain angle, it forces the adjacent second connecting plate 605 to rotate through the forcing member 7, so the vibration rhythm of the connecting plate 502 is different. This is repeated, resulting in multiple connecting plates 502 moving back and forth in a wave-like manner. This allows multiple sets of vibrating rods 501 to beat the mold box in a wave-like manner as a whole. A single driving force can effectively improve the demolding of the mold box, effectively save energy, and improve the demolding effect of the mold box.

[0024] like Figures 9 to 11 As shown, in some embodiments, the forcing member 7 includes an actuating block 701 constructed on the outer side of the pivot rod 601 near the free end. A forcing block 702 for contacting the actuating block 701 is constructed on the second connecting plate 605. A return spring 703 is installed between the vibrating rod 501 and the pressure plate 4011 to form a gap between the actuating block 701 and the adjacent forcing block 702 under normal conditions. When the outermost second connecting plate 605 rotates under the electric motor, the corresponding pivot rod 601 rotates, causing the actuating block 701 to rotate. After rotating a certain angle, the actuating block 701... This will contact the forcing block 702 on the adjacent second connecting plate 605, thereby causing the forcing block 702 to rotate synchronously. The return spring 703 has a certain preload under normal conditions to ensure that the contact block 701 and the forcing block 702 remain in contact during the continuous rotation of the pivot rod 601. After the motor is turned off, the return spring 703 will cause the second connecting plate 605 to rotate and reset under the action of the spring, so that a certain gap is maintained between the adjacent contact block 701 and the forcing block 702, so as to ensure that when the motor is started again, the multiple sets of vibration rods 501 can continuously beat the mold box in a wave-like form.

[0025] like Figures 9 to 11As shown, in some embodiments, one end of the second connecting plate 605 is constructed with a protective cylinder 10, one end of the pivot rod 601 is rotatably inserted into the protective cylinder 10, and the actuating block 701 is located inside the protective cylinder 10. When the mold box is in an inverted state and when the mold box is vibrated and tapped, some concrete debris will fall. In order to prevent concrete debris from falling between the forcing block 702 and the actuating block 701, the protective cylinder 10 is designed so that the forcing block 702 and the actuating block 701 are located inside the protective cylinder 10, which effectively prevents external concrete debris from falling onto the forcing block 702 and the actuating block 701, and ensures the stability of the subsequent multiple sets of vibrating rods 501 when continuously tapping the concrete in a wave-like manner.

[0026] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
