Description

Technical Field

[0001] This invention relates to the field of concrete block molding technology, specifically to a concrete block molding equipment and a concrete block preparation method. Background Technology

[0002] Concrete blocks, as a fundamental material in the construction industry, are widely used in wall construction, road paving, and other applications. With the acceleration of industrialization in the construction industry, the sector has placed increasingly stringent demands on the production efficiency and quality of concrete blocks. While the current market offers a wide variety of concrete block molding equipment, three major pain points are prevalent: firstly, low production efficiency, making it difficult to meet the needs of large-scale construction; secondly, high energy consumption, which contradicts the trend of green and low-carbon development; and thirdly, insufficient stability in finished product quality, easily leading to problems such as uneven strength and dimensional deviations. In recent years, the penetration of automation technology has driven equipment upgrades, with some new molding equipment incorporating hydraulic drive systems and intelligent control systems, improving precision and ease of operation. However, these improvements have not fundamentally solved the inherent defects of traditional equipment. For example, the energy loss problem of hydraulic systems has not been completely resolved, and the adaptability of intelligent control algorithms to complex raw material characteristics needs to be strengthened, thus limiting the potential for further improvements in production efficiency and quality. This situation reflects the urgency of technological upgrading in the industry and provides direction for further integrating technologies such as fluid transmission optimization and artificial intelligence adaptive control, aiming to achieve efficient, low-consumption, and high-quality stable output of concrete blocks.

[0003] In existing technologies, vibration compaction and extrusion molding are the mainstream methods for forming concrete blocks. Vibration compaction uses high-frequency vibration to achieve dense concrete forming. Its advantages lie in its simple equipment structure and low initial investment cost, but its shortcomings are also quite prominent: on the one hand, the noise pollution generated by high-frequency vibration is serious, which does not meet the environmental protection requirements of modern workshops; on the other hand, the energy consumption of the vibration process is relatively high, which conflicts with the concept of low-carbon production. Extrusion molding directly shapes the concrete blank through mechanical pressure. Although it has the significant advantage of high production efficiency, it places extremely high demands on the processing precision of the molds, and uneven stress distribution during the extrusion process can easily lead to edge damage of the products, increasing the defect rate and thus making the molding equipment less effective.

[0004] In addition, traditional molding equipment relies heavily on manual operation in the material conveying and demolding process, which is not only labor-intensive and has limited work efficiency, but also makes it difficult to ensure the quality consistency of each batch of products through manual control. This has become a major bottleneck restricting large-scale and standardized production, and consequently makes the molding equipment less convenient to use.

[0005] Furthermore, in the molding and unloading stage, current processes often require an additional independent air source, using specialized nozzles to spray gas and remove debris from the surface of the molded product. This design not only necessitates separate investment in air source equipment, such as air compressors, air tanks, and air circuit control systems, increasing the initial cost of the molding equipment; but also results in high long-term operating costs due to continuous power consumption during air source operation, replacement costs for worn nozzles, and manual labor for regular air circuit cleaning. Consequently, the cost of the molding equipment is high both in terms of initial construction and operating costs. Therefore, it is essential to invent a concrete block molding device and a concrete block preparation method to address these issues. Summary of the Invention

The extrusion frame 6 is fixed at the end of the drive rod of the cylinder 5, and the fixed block 7 is fixed at the middle of the drive rod of the cylinder 5. A connecting structure is provided at one end of the fixed block 7, connecting... The connecting structure includes a connecting frame 8, with a sliding frame 9 rotatably connected to the other end of the connecting frame 8.

A rotating frame 12 is provided on the outer surface of the sliding frame 9. Several connecting teeth 13 are fixed at intervals on both sides of the rotating frame 12. The connecting teeth 13 are meshed with gears 14. A stabilizing block 15 is rotatably connected to the outer surface of the gears 14. A driving frame 16 is fixed in the middle of the gears 14. A vibrating frame 17 is slidably connected to the outer surface of the driving frame 16. A through groove 18 is provided on the lower side of the vibrating frame 17.

[0038] Please refer to it again. Figure 1 - Figure 8As shown, a fixed block 7 is rotatably connected to one end of the upper part of the connecting frame 8, and the other end of the connecting frame 8 is rotatably connected to one end of the sliding frame 9. The outer surface of the sliding frame 9 is slidably connected to the inner wall of the slide groove 2. The vertical section of the sliding frame 9 is T-shaped, and the cross section of the slide groove 2 is T-shaped. A groove 10 is opened in the middle of the lower side of the sliding frame 9. The upper side of the rack 11 is fixed to the inner wall of the groove 10. The rack 11 is meshed with the connecting teeth 13. One side of the connecting teeth 13 is fixed at intervals to the side of the rotating frame 12. The outer surface of the rotating frame 12 is rotatably connected to the middle of one side of the frame body 1. The gear 13 meshes with the gear 14. The outer surface of the gear 14 is rotatably connected to the inner wall of the stabilizing block 15. The upper end of the stabilizing block 15 is fixed to one side of the frame 1. One end of the gear 14 is fixed with a drive frame 16. The vertical section of the drive frame 16 is L-shaped. The outer surface of the drive frame 16 is slidably connected to the inner wall of the through groove 18. The through groove 18 passes through the lower side of the vibration frame 17. The outer surface of the vibration frame 17 is slidably connected to the inner wall of the middle part of the frame 1. The middle part of the frame 1 is hollowed out. The upper surface of the vibration frame 17 is in contact with the lower surface of one of the molds 30.

[0039] The specific implementation process is as follows: The fixed block 7 is moved by the cylinder 5. The fixed block 7 is rotatably connected to the connecting frame 8 at one end, which drives the sliding frame 9 rotatably connected to the other end. The sliding operation is completed under the limitation of the sliding groove 2 opened on one side of the frame body 1. The sliding sliding frame 9 will drive the rack 11 fixed in the groove 10 in the middle of its lower side to move synchronously.

[0040] When the fixed block 7 initially moves downward, the surface of the sliding frame 9 contacts the outer surface of the rotating frame 12, which is rotatably connected to one side of the frame body 1, and remains stable under the squeezing action of the connecting teeth 13. After the fixed block 7 moves downward a certain distance, the rack 11 connected in the middle of the sliding frame 9 meshes with the connecting teeth 13 fixed at intervals on the side of the rotating frame 12, thereby driving the rotating frame 12 to rotate. The rotating frame 12, through the connected connecting teeth 13, drives the gear 14 meshing with it to rotate at high speed under the support of the support frame 21 fixed to one side of the frame body 1. The high-speed rotating gear 14 drives the drive frame 16, which is fixed at one end, to rotate synchronously. Since the vertical cross-section of the drive frame 16 is L-shaped, based on the principle of eccentric wheel motion, it works with the through groove 18 during rotation to drive the vibrating frame 17 to slide up and down rapidly under the limit of the inner wall of the frame body 1, producing a vibration effect, and vibrating the mold 30 containing the concrete mixture that has been moved onto the vibrating frame 17. Vibration can eliminate air bubbles in the concrete mixture and improve the density of the raw materials.

[0041] After the fixed block 7 continues to move down a certain distance, the surface of the sliding frame 9 contacts the outer surface of the rotating frame 12 again and remains stable under the pressure of the connecting teeth 13, at which point the vibration stops. In the stopped state, the upper surface of the vibrating frame 17 remains flush with the inner wall plane of the frame body 1. As the extrusion frame 6, which is fixed at the end of the cylinder 5 drive rod, moves, and the fixed block 7 is fixed in the middle of the cylinder 5 drive rod, the extrusion frame 6 can extrude the mold 30 containing the concrete mixture after vibration treatment, so that the concrete mixture in the mold 30 is compressed and formed, thereby achieving the effect of vibration and extrusion in one. The air bubbles are first discharged by vibration, which allows the raw materials to be more tightly combined during extrusion molding, avoiding subsequent breakage problems, thereby improving the performance of the molding equipment.

[0042] In addition, when the fixed block 7 moves upward, although the vibration frame 17 will also vibrate through the cooperation of the rack 11, connecting teeth 13 and gear 14, the vibration has no effect on the finished product.

[0043] Example 2

[0044] Please see Figure 1 - Figure 8 As shown, an automatic loading and unloading function has been added based on Embodiment 1;

[0045] Please refer to it again. Figure 1 - Figure 8 As shown, one end of the sliding frame 9 is rotatably connected to the connecting frame 19, and the other end of the connecting frame 19 is rotatably connected to the push frame 20. One end of the frame body 1 is fixed with a support frame 21. A first placement groove 22 is opened on one side of the support frame 21, and a second placement groove 23 is opened on the other side of the support frame 21. A limiting groove 24 is opened at one end of the frame body 1. The connecting frame 19 and the connecting frame 8 are staggered. One end of the connecting frame 19 is rotatably connected to one end of the push frame 20. The outer surface of the push frame 20 is slidably connected to the inner wall of the limiting groove 24. The cross-section of the push frame 20 is L-shaped. The outer surface of the push frame 20 is in contact with the outer surface of one of the molds 30.

[0046] The specific implementation process is as follows: The fixed block 7 is moved by the cylinder 5. The fixed block 7 drives the sliding frame 9, which is rotatably connected to the connecting frame 8 at one end, to complete the sliding operation under the limit of the sliding groove 2 opened on one side of the frame body 1. The sliding frame 9 drives the push frame 20 to slide under the limit of the limit groove 24 opened at one end of the frame body 1, through the connecting frame 19 rotatably connected to the connecting frame 8 at the same end.

[0047] As the fixed block 7 moves downward, the extrusion frame 6 extrudes the mold 30 containing the concrete mixture. At this time, the push frame 20, driven by the connecting frame 19, moves away from the cylinder 5 and slides to the side of the support frame 21 fixed to one end of the frame body 1. During this process, the push frame 20 supports the mold 30 in the first placement slot 22 on one side of the support frame 21. When the push frame 20 is completely away from the support frame 21, the mold 30 falls into the frame body 1 under gravity, and the push frame 20 continues to move away a certain distance.

[0048] Subsequently, as the fixed block 7 moves upward, the pusher 20, driven by the connecting frame 19, pushes the empty mold 30 that has fallen into the frame 1. The pusher 20 will only push the mold 30 when the initial plane of the sliding frame 9 contacts the surface of the rotating frame 12 and remains stable under the pressure of the connecting teeth 13. In this way, the molds 30 will squeeze the forming mold 30 to one side one by one, so that the unformed mold 30 moves to the vibrating frame 17 below the extrusion frame 6;

[0049] Simultaneously, the pushed empty mold 30 moves to the second placement groove 23 on the other side of the support frame 21, and the concrete mixture in the second placement groove 23 enters the mold 30 from the discharge port. In this way, the equipment completes the cycle and achieves automatic loading and unloading, eliminating the need for manual operation by the staff, thus improving the ease of use of the molding equipment.

[0050] Example 3

[0051] Please see Figure 1 - Figure 8 As shown, an automatic cleaning function has been added based on Embodiment 1;

[0052] Please refer to it again. Figure 1 - Figure 8 As shown, a connecting pipe 25 is fixed to one end of the fixing block 7, and a sliding plate 26 is fixed to the other end of the connecting pipe 25. A bellows 27 is slidably connected to the outer surface of the sliding plate 26. A box groove 28 is opened in the middle of the bellows 27. Several through holes 29 are opened at the lower end of the box groove 28. One end of the connecting pipe 25 is fixed to one end of the fixing block 7, and the other end of the connecting pipe 25 is fixed to the middle of the sliding plate 26. The vertical section of the connecting pipe 25 is U-shaped. The outer surface of the sliding plate 26 is slidably connected to the inner wall of the box groove 28. Several through holes 29 penetrate the middle of the lower end of the bellows 27. Both ends of the bellows 27 are fixed to one side of the frame 1.

[0053] The specific implementation process is as follows: The fixed block 7 is moved by the cylinder 5. When the fixed block 7 moves downward, the connecting pipe 25 fixed to it moves downward simultaneously. The sliding plate 26 fixed to the other end of the connecting pipe 25 slides down under the constraint of the groove 28 opened in the air box 27 on the frame 1. The sliding plate 26 slides down and compresses the air in the air box 27, causing the air to accelerate and be discharged from the through hole 29 opened on the lower side of the groove 28. The discharged air blows air onto the mold 30 below, which has been formed and contains the formed concrete blocks, blowing away the debris on the surface of the concrete blocks, achieving an automatic cleaning effect. No additional air source is needed for the blowing and cleaning operation, thereby reducing the cost of the forming equipment and its operation.

[0054] It is worth noting that the connecting pipe 25 passes through the top of the air box 27. When the slide plate 26 moves down, air enters the air box 27 through the through-hole; when it moves up, air is discharged through the through-hole, which does not affect the normal operation of the equipment.

[0055] A method for preparing concrete blocks includes the following steps:

[0056] S1. Automatic feeding: The fixed block 7 is driven to move upward by the cylinder 5. The moving fixed block 7 is connected to the connecting frame 8 and the sliding frame 9. The connecting frame 19 pushes the mold 30 falling in the support frame 21 through the push frame 20. When the moving mold 30 moves to the second placement slot 23 opened on one side of the support frame 21, the concrete mixture loaded in the second placement slot 23 automatically fills the empty mold 30.

[0057] S2, Vibration extrusion molding: The fixed block 7 is driven to move down by the cylinder 5. The moving fixed block 7 is connected to the sliding frame 9 through the connecting frame 8 and the gear 14 to drive the vibration frame 17 to slide up and down quickly. At the same time, the extrusion frame 6 is driven to move down by the cylinder 5. The moving extrusion frame 6 extrudes and molds the concrete mixture in the mold 30.

[0058] S3, Debris removal: The cylinder 5 drives the fixed block 7 to move down. The moving fixed block 7 drives the slide plate 26 to slide in the air box 27 through the connected pipe 25. The sliding slide plate 26 compresses the air, causing the air to be discharged from the through hole 29, thus removing the debris from the surface of the molded product that has been transported here.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
