Description

Technical Field

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

[0002] A color mixing device for concrete products is a device specifically used to achieve the mixing of multiple colors of concrete in the production of concrete products to meet the color requirements of the products. After color mixing is completed, a mold is also required for the forming operation to manufacture precast building components. In the aspect of self-insulating concrete, by adding thermal insulation aggregates or thermal insulation materials to the concrete, the concrete structure itself has good thermal insulation performance, effectively reducing the heat transfer of the building and reducing building energy consumption, and is used as an energy-saving building material in the high-efficiency energy-saving industry.

[0003] However, when the existing color mixing device and color mixing method for concrete products are in use, after color mixing is completed, the concrete needs to be taken out and then fed into the mold for the forming operation to make concrete products, which is not convenient and fast enough and affects the forming efficiency. At the same time, during forming, due to the concrete not being closely arranged, defects such as air bubbles and cracks are likely to occur, affecting the forming quality. Moreover, after forming is completed, it is not easy to unload the concrete products from the mold, thus affecting the forming efficiency and quality.

[0091] A method for mixing colors of concrete products, which is 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 limit block 808 and the sliding rod 807 can move downward through the strip-shaped opening 806. When the second limit 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 limit block 808 passes over the third inclined surface 803, the triangular block 802 can extend outward under the action of the fourth spring 903, and the limiting surface 804 abuts against the top of the second limit block 808, so that the upper mold 1202 can be limited after the mold closing is completed. Then, the mold is placed in the placement groove 11 and conveyed along with the conveyor belt 1001;

[0093] S2: The concrete product is subjected to color mixing treatment in the cylinder body 102. When the mold is conveyed to the feeding station, the second moving module 2401 drives the moving frame 2402 to move downward. At the same time, the pressure control mechanism drives the transparent disk 2403 to move downward. The angle mark 201 indicated by the pointer 202 is observed through the visual sensor 207. Then, the motor 205 is started, and the rotation of the motor 205 drives the rotation of the gear 206, so that the rotating column 2405 is driven to rotate through the gear ring 203, and rotates a certain angle so that the rectangular groove 2406 is aligned with the rectangular rod 18, so that the rectangular rod 18 can be inserted into the rectangular groove 2406. Then, the motor 205 is reversed, and the rectangular rod 18 can be driven to rotate through the rotating column 2405, so as to drive the rotating disk 16 to rotate, so that the second through hole 17 is aligned with the first through hole 15;

[0094] S3: Then, the first moving module 27 drives the first moving block 21 and the feeding valve 22 to move towards the feeding pipe 19. When the feeding valve 22 moves towards 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 push rod 702, it can drive the lifting plate 26 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, and the lifting plate 26 abuts against the top of the stop block 604. At the same time, when the lifting plate 26 moves downward, it can drive the first limit block 805 to move downward synchronously through the second U-shaped plate 701. Similarly, after the lifting plate 26 moves in place, the lifting plate 26 can also be limited, which is more stable and reliable.

[0095] S4: When the feeding valve 22 abuts against the first inclined surface 502, the sealing block 501 can be pushed to move in the direction close 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 feeding pipe 19. Then, the feeding valve 22 is opened. At this time, the concrete in the cylinder 102 passes through the first moving block 21, the feeding valve 22 and the feeding pipe 19 and enters the fixed pipe 13 and enters the lower mold 1201 and the upper mold 1202 for molding. After a certain amount of concrete is supplied, there is concrete in the feeding pipe 19. At this time, the feeding valve 22 is closed. At the same time, the feeding valve 22 is driven to move and reset by the first moving module 27. At this time, the sealing block 501 can be moved and reset under the action of the second spring 506 and seal the feeding pipe 19, so that the mixed concrete can be supplied into the mold. It is more convenient and quick to use and can improve the molding efficiency.

[0096] S5: Then, the transparent plate 2403 is driven to continue to move downward by the second moving module 2401. When the transparent plate 2403 contacts the concrete, the concrete in the mold can be squeezed. At the same time, the first spring 303 is gradually compressed, and the distance sensor 305 detects the distance change of the sensing block 304 to determine the compression amount of the first spring 303, thereby controlling the squeezing force on the concrete, so that the aggregate inside the concrete is arranged more tightly, the porosity is reduced, thereby improving the density of the concrete, reducing defects such as bubbles and cracks on the surface of the concrete, and improving the molding quality. After the extrusion is completed, the motor 205 is started to drive the rotating disk 16 to rotate, so that the second through hole 17 is staggered 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 movable frame 2402 to move upward and reset, and the pressure control mechanism drives the transparent plate 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, the concrete temporarily stored in the fixed cylinder 402 can be squeezed. 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 body 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 feeding pipe 19 can be drawn into the fixed cylinder 402 through the second hose 405 and the U-shaped tube 403 for temporary storage, thereby facilitating the recycling of the excess concrete and avoiding waste.

[0098] S7: After the forming is completed, the second push rod 904 can be pushed, so that the triangular block 802 retracts into the sliding groove 901. At the same time, the fourth spring 903 is compressed, so that the triangular block 802 disengages from the first limit block 805 and the second limit block 808. At this time, the lifting plate 26 and the upper mold 1202 are no longer limited, and the lifting plate 26 can move upward under the action of the third spring 603, so as to facilitate unloading the formed product from the lower mold 1201 and improve the forming efficiency.
