Description

Technical Field

[0001] This invention relates to the technical field of special equipment for the production of energy-saving building materials, specifically to a color mixing device and method for concrete products. Background Technology

[0002] A concrete product color mixing device is a specialized piece of equipment used in the production of concrete products to mix multiple colors of concrete to meet the color requirements of the products. After the color mixing is completed, a mold is used for molding to manufacture precast building components. In the field of self-insulating concrete, by adding insulating aggregates or insulating materials to the concrete, the concrete structure itself has good thermal insulation performance, effectively reducing heat transfer from the building and lowering building energy consumption. It is used as an energy-saving building material in the high-efficiency energy-saving industry.

[0003] However, existing concrete product mixing devices and methods require the concrete to be removed after mixing and then fed back into the mold for molding to produce concrete products. This is inconvenient and slow, affecting molding efficiency. Furthermore, during molding, the concrete may not be tightly packed, leading to defects such as air bubbles and cracks, which affect the quality of the product. Moreover, after molding, it is not easy to remove the concrete product from the mold, thus affecting both molding efficiency and quality.

[0004] Therefore, we propose a color mixing device and method for concrete products. Summary of the Invention

[0089] Telescopic mechanism

[0090] A sliding groove 901 is provided in the mounting block 801. A sliding plate 902 is slidably connected in the sliding groove 901. A fourth spring 903 is fixedly connected between the sliding plate 902 and the sliding groove 901. A triangular block 802 is fixedly connected to the side wall of the sliding plate 902. A second push rod 904 is fixedly connected to the side wall of the sliding plate 902. The other end of the second push rod 904 passes through the side wall of the lower mold 1201.

[0091] A method for mixing colors in concrete products, applied to a concrete product color mixing device, includes the following steps:

[0092] S1: When the upper mold 1202 and the lower mold 1201 are closed, the second limiting block 808 and the sliding rod 807 can move downward through the strip opening 806. When the second limiting block 808 abuts against the third inclined surface 803, it can push the triangular block 802 to slide into the sliding groove 901. At the same time, the fourth spring 903 is compressed. When the second limiting block 808 passes the third inclined surface 803, the triangular block 802 can extend outward under the action of the fourth spring 903, and make the limiting surface 804 abut against the top of the second limiting block 808. Thus, after the mold is closed, the upper mold 1202 can be limited. Then, the mold is placed in the placement groove 11 and conveyed with the conveyor belt 1001.

[0093] S2: The concrete product undergoes color mixing within the cylinder 102. When the mold is transported to the feeding station, the second moving module 2401 drives the moving frame 2402 to move downwards. Simultaneously, the pressure control mechanism drives the transparent disc 2403 to move downwards. The angle indicator 201 indicated by the pointer 202 is observed through the vision sensor 207. Then, the motor 205 is started. The rotation of the motor 205 drives the rotation of the gear 206, which in turn drives the rotating column 2405 to rotate through the gear ring 203. The rotating column 2405 rotates at a certain angle so that the rectangular slot 2406 is aligned with the rectangular rod 18, allowing the rectangular rod 18 to be inserted into the rectangular slot 2406. Then, the motor 205 is started in reverse, which drives the rectangular rod 18 to rotate through the rotating column 2405, thereby driving the rotating disc 16 to rotate, aligning the second through hole 17 with the first through hole 15.

[0094] S3: Next, the first moving module 27 drives the first moving block 21 and the feeding valve 22 to move closer to the feeding pipe 19. When the feeding valve 22 moves closer to the feeding pipe 19, the pushing block 705 can slide along the top of the upper mold 1202. When the second inclined surface 706 abuts against the upper end of the first pushing rod 702, the lifting plate 26 can be driven to move downward through the connecting plate 703 and the second U-shaped plate 701. At the same time, the third spring 603 is compressed, causing the lifting plate 26 to abut against the top of the stop block 604. Meanwhile, when the lifting plate 26 moves downward, the first limiting block 805 can be driven to move downward synchronously through the second U-shaped plate 701. Similarly, after the lifting plate 26 moves into place, it can also be limited, making it more stable and reliable.

[0095] S4: When the feeding valve 22 abuts against the first inclined surface 502, it can push the sealing block 501 to move closer to the L-shaped block 503. At the same time, the second spring 506 is compressed, so that the feeding valve 22 is aligned with the feed pipe 19. Then, the feeding valve 22 is opened. At this time, the concrete in the cylinder 102 enters the fixed pipe 13 through the first moving block 21, the feeding valve 22 and the feed pipe 19 and enters the lower mold 1201 and the upper mold 1202 for molding. After a certain amount of concrete is supplied, there is also concrete in the feed pipe 19. At this time, the feeding valve 22 is closed. At the same time, the feeding valve 22 is moved and reset by the first moving module 27. At this time, the sealing block 501 can move and reset under the action of the second spring 506 and seal the feed pipe 19, which makes it easier to supply the mixed concrete into the mold. It is more convenient and faster to use and can improve the molding efficiency.

[0096] S5: Next, the second moving module 2401 drives the transparent disk 2403 to continue moving downward. When the transparent disk 2403 comes into contact with the concrete, it can squeeze the concrete in the mold. At the same time, the first spring 303 is gradually compressed. The distance sensor 305 detects the distance change of the sensing block 304, which can determine the compression amount of the first spring 303, thereby controlling the squeezing force on the concrete, making the aggregate inside the concrete more compact, reducing porosity, thereby improving the density of the concrete, reducing defects such as bubbles and cracks on the concrete surface, and improving the molding quality. After the squeezing is completed, the motor 205 is started, which can drive the rotating disk 16 to rotate, so that the second through hole 17 is misaligned with the first through hole 15, so that the fixed disk 14 is in a sealed state. Then, the second moving module 2401 drives the moving frame 2402 to move upward and reset, and the pressure control mechanism drives the transparent disk 2403 to move upward and reset.

[0097] S6: When the second moving module 2401 moves downward, it can drive the moving column 409 to slide downward along the fixed cylinder 402. At this time, it can squeeze the concrete temporarily stored in the fixed cylinder 402. At the same time, the first electric valve 404 is closed and the second electric valve 407 is opened, so that the concrete in the fixed cylinder 402 can be squeezed back into the cylinder 102. When the moving frame 2402 moves upward and resets, it can drive the moving column 409 to move upward and reset. At the same time, the first electric valve 404 is opened and the second electric valve 407 is closed. At this time, the excess concrete in the feed pipe 19 can be drawn into the fixed cylinder 402 through the second hose 405 and the U-shaped pipe 403 for temporary storage, so as to facilitate the recycling of excess concrete and avoid waste.

[0098] S7: After molding is completed, the second push rod 904 can be pushed to retract the triangular block 802 into the sliding groove 901. At the same time, the fourth spring 903 is compressed, causing the triangular block 802 to disengage from the first limiting block 805 and the second limiting block 808. At this time, the lifting plate 26 and the upper mold 1202 are no longer limited. The lifting plate 26 can move upward under the action of the third spring 603, which makes it easier to unload the molded product from the lower mold 1201 and improve the molding efficiency.
