Description

Technical Field

[0001] This utility model relates to the technical field of precast concrete component production equipment, and in particular to a precast component production line. Background Technology

[0002] Existing precast component production lines, when producing precast slope protection blocks, hollow or solid hexagonal blocks, and various cover plates—components with varying shapes and sizes—often use a method of fixing multiple plastic molds within a mold frame for easy stacking, curing, and on-line transfer. Demolding involves flipping the entire component. However, due to attenuation and insufficient transmission of vibration force from the mold frame to the plastic mold, some components often fail to detach. This necessitates extending the vibration time or halting the production line to remove the mold and frame as a whole. This process is cumbersome and delays production. Furthermore, components that have already been demolded are highly susceptible to breakage during prolonged vibration, leading to decreased demolding efficiency and increased component breakage rate. In addition, the need to fix the molds within the mold frame necessitates a mold fixing device, resulting in a complex mold frame structure, cumbersome mold assembly, long processing time, and the risk of components failing to detach if not properly assembled. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a precast component production line that is conducive to improving the demolding success rate, reducing the component damage rate, simplifying the mold frame structure, and making the production efficiency less affected.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A precast component production line includes a mold and frame separation conveyor line, a material feeding conveyor line, a component demolding conveyor line, and a curing kiln. One end of the mold and frame separation conveyor line is connected to the outlet of the curing kiln, and the other end is provided with a mold and frame separation station. The mold and frame separation station is connected to one end of the material feeding conveyor line and the component demolding conveyor line, respectively. The material feeding conveyor line is provided with a mold and frame assembly station. The other end of the component demolding conveyor line is connected to the mold and frame assembly station, and the other end of the material feeding conveyor line is connected to the inlet of the curing kiln.

[0006] As a further improvement to the above technical solution: the mold frame separation conveyor line is also provided with a destacking station and a first flipping station, and the destacking station, the first flipping station and the mold frame separation station are arranged in sequence.

[0007] As a further improvement to the above technical solution: the fabric conveying line is also provided with a second flipping station, a spraying station, a fabric conveying station and a stacking station in sequence, and the mold frame assembly station is located between the second flipping station and the spraying station.

[0008] As a further improvement to the above technical solution: the fabric placement station is equipped with a fabric placement machine, and the fabric placement machine is equipped with multiple fabric placement ports.

[0009] As a further improvement to the above technical solution: the component demolding conveyor line is provided with a demolding station, a component mold separation station and a slag removal station in sequence.

[0010] As a further improvement to the above technical solution: the demolding station is equipped with a vibrating conveyor demolding table.

[0011] As a further improvement to the above technical solution: a component stacking and packaging station is provided on one side of the component mold separation station.

[0012] As a further improvement to the above technical solution: the inlet of the curing kiln is provided with an inlet conveying track, and an inlet transfer trolley is provided on the inlet conveying track; the outlet of the curing kiln is provided with an outlet conveying track, and an outlet transfer trolley is provided on the outlet conveying track.

[0013] As a further improvement to the above technical solution: the mold frame separation conveyor line, the material conveyor line, and the component demolding conveyor line are all located between the kiln inlet conveyor track and the kiln outlet conveyor track.

[0014] As a further improvement to the above technical solution: the mold frame separation conveyor line is arranged in parallel with the fabric conveyor line.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] This utility model discloses a precast component production line. After the precast component is cured in the curing kiln, the mold is transferred to the mold-frame separation conveyor line. Upon reaching the mold-frame separation station, the mold, along with the precast component, separates from the mold frame and enters the component demolding conveyor line, while the mold frame is transferred to the material feeding conveyor line. After the precast component is demolded, the mold and mold frame reassemble at the mold-frame reassembly station, meaning the mold returns to the mold frame. After the mold completes the material feeding, it is transferred again to the curing kiln for curing via the material feeding conveyor line, and this cycle repeats. Because the mold frame and mold are transported separately during demolding, the demolding force can act directly on the mold, no longer affected by the mold frame, which significantly improves the demolding success rate. Furthermore, there is no need for a fixed connection structure between the mold and mold frame, simplifying the mold frame structure and assembly process, thereby reducing costs. Furthermore, each mold removed from the mold frame is demolded separately, and the precast components that have been demolded will not be damaged due to excessive vibration, thereby reducing the component breakage rate. If a single mold is damaged or a component is difficult to demold, it can be quickly replaced without causing the entire production line to stop, which helps to ensure the production efficiency of the entire line.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Figure 1 This invention illustrates an embodiment of the precast component production line. The precast component production line of this embodiment includes a mold and frame separation conveyor line 1, a material feeding conveyor line 2, a component demolding conveyor line 3, and a curing kiln 4. One end of the mold and frame separation conveyor line 1 is connected to the outlet of the curing kiln 4, and the other end is provided with a mold and frame separation station 11. The mold and frame separation station 11 is connected to one end of both the material feeding conveyor line 2 and the component demolding conveyor line 3. The material feeding conveyor line 2 is provided with a mold and frame assembly station 21. The other end of the component demolding conveyor line 3 is connected to the mold and frame assembly station 21, and the other end of the material feeding conveyor line 2 is connected to the inlet of the curing kiln 4.

[0026] In this embodiment of the precast component production line, after the precast components are cured in the curing kiln 4, the mold is transferred to the mold frame separation conveyor line 1. Upon reaching the mold frame separation station 11, the mold, along with the precast components, separates from the mold frame and enters the component demolding conveyor line 3 (e.g., by a robotic arm gripping it). The mold frame is then transferred to the material feeding conveyor line 2. After the precast components are demolded, the mold and mold frame are reassembled at the mold frame reassembly station 21 (e.g., by a robotic arm gripping it and placing it back into the mold frame), meaning the mold returns to the mold frame. After the mold completes the material feeding, it is transferred again to the curing kiln 4 via the material feeding conveyor line 2 for curing, and this cycle repeats. Because the mold frame and mold are transported separately during demolding, the demolding force can act directly on the mold without being affected by the mold frame, thus significantly improving the demolding success rate. Furthermore, there is no need for a fixed connection structure between the mold and mold frame, simplifying the structure and assembly process of the mold frame, thereby reducing production, assembly, and usage costs. Furthermore, each mold removed from the mold frame is demolded separately, and the precast components that have been demolded will not be damaged due to excessive vibration, thereby reducing the component breakage rate. If a single mold is damaged or a component is difficult to demold, it can be quickly replaced without causing the entire production line to stop, which helps to ensure the production efficiency of the entire line.

[0027] Furthermore, in this embodiment, the mold frame separation conveyor line 1 is also provided with a destacking station 12 and a first flipping station 13, which are arranged sequentially with the destacking station 12, the first flipping station 13, and the mold frame separation station 11. The destacking station 12 is used to disassemble the stacked mold frames sequentially and place them on the mold frame separation conveyor line 1, and the first flipping station 13 is used to make the mold opening face downwards, which is convenient for subsequent demolding.

[0028] Furthermore, in this embodiment, the material conveying line 2 is also provided with a second flipping station 22, a spraying station 23, a material laying station 24, and a stacking station 25 in sequence. The mold frame assembly station 21 is located between the second flipping station 22 and the spraying station 23. The second flipping station 22 is used to flip the mold frame again so that the mold frame faces upward, making it easier for the mold to be put back into the mold frame later. The mold and the mold frame are assembled again at the mold frame assembly station 21 and enter the next station together. The spraying station 23 is used to spray the release agent onto the surface of the mold cavity to facilitate demolding of the component. The material laying station 24 is used to fill the mold with concrete. After the material laying is completed, the stacking station 25 is used to stack the mold frames one by one to reduce the area occupied and save space in the curing kiln 4.

[0029] In a preferred embodiment, the fabric placement station 24 is equipped with a fabric placement machine, which has multiple fabric placement ports and can simultaneously place fabric onto multiple molds, thereby improving the efficiency of fabric placement.

[0030] Furthermore, in this embodiment, the component demolding conveyor line 3 is sequentially provided with a demolding station 31, a component mold separation station 32, and a flipping and cleaning station 33. The mold after being separated from the mold frame is transferred to the demolding station 31, which is used to remove the component from the mold. The component mold separation station 32 is used to separate the precast component from the mold. The mold is transferred to the flipping and cleaning station 33 to clean the debris in the mold cavity. Then, the mold is flipped to restore the mold to the opening facing upwards so that the material can be laid. Of course, the flipping process also helps to discharge the debris from the mold cavity.

[0031] In a preferred embodiment, the demolding station 31 is equipped with a vibrating conveyor demolding table. While the mold is being conveyed to the next station, the precast component is ejected from the mold through vibration, achieving continuous mold transfer and demolding, and shortening the demolding cycle. Of course, other demolding methods can also be used in other embodiments.

[0032] In a preferred embodiment, a component stacking and packaging station 5 is provided on one side of the component mold separation station 32. Preferably, a robot equipped with a vacuum suction cup can be used to grab various prefabricated components after demolding and stack and package the prefabricated components for batch transportation.

[0033] Furthermore, in this embodiment, the entrance of the curing kiln 4 is provided with an inlet conveying track 41, and an inlet transfer trolley 42 is provided on the inlet conveying track 41. The inlet transfer trolley 42 can be used to transfer the stacked mold frames, molds and components from the stacking station 25 into the curing kiln 4 as a whole. The exit of the curing kiln 4 is provided with an outlet conveying track 43, and an outlet transfer trolley 44 is provided on the outlet conveying track 43. The outlet transfer trolley 44 can be used to transfer the cured mold frames, molds and components out of the curing kiln 4 as a whole and transfer them to the destacking station 12. The structure is reasonable and effective.

[0034] As a preferred embodiment, the mold frame separation conveyor line 1, the material conveyor line 2, and the component demolding conveyor line 3 are all located between the kiln inlet conveyor track 41 and the kiln outlet conveyor track 43. This can make full use of the space along the length of the curing kiln 4, making the entire production line layout compact and helping to save the factory floor space.

[0035] In a preferred embodiment, the mold frame separation conveyor line 1 and the fabric conveyor line 2 are arranged in parallel to facilitate the transfer of the mold frame from the mold frame separation conveyor line 1 to the fabric conveyor line 2.

[0036] The working principle of this precast component production line is as follows:

[0037] After the precast components are cured in the curing kiln 4, the mold frame stacks are transferred to the unstacking station 12 via the kiln exit transfer trolley 44. At the unstacking station 12, the mold frames, along with the molds, are placed one by one on the mold frame separation conveyor line 1, and then conveyed to the first flipping station 13 for flipping, so that the mold opening faces downwards. Then, they are conveyed to the mold frame separation station 11, where the mold frames are picked up and placed on the material conveying line 2. After being separated from the mold frame, the molds enter the component demolding conveyor line 3. Through the demolding station 31, the molds are demolded while flowing. Then, the component mold separation station 32 allows the components to leave the mold cavity and enter the component stacking and packaging station 5 for stacking and packaging. The molds are diverted to the flipping and slag cleaning station 33 for internal cavity cleaning and flipping. After cleaning, the mold cavity is flipped upwards. The mold frames that have been diverted from the molds and entered the material conveying line 2 are flipped again at the second flipping station 22 to achieve reset. At the mold frame reassembly station 21, they are reassembled with the cleaned molds, and the molds return to the mold frame. The assembled mold is transported by the mold frame to the spraying station 23, where an automatic spraying device sprays release agent onto the inner cavity of the mold to facilitate demolding of the precast components produced later. After spraying, it is transported to the material placement station 24, where an automatic material placement machine performs the material placement operation. After material placement, the mold is transported to the stacking station 25, where the mold frames are stacked layer by layer. Then, the mold is transferred to the curing kiln 4 by the kiln transfer trolley 42 for curing until curing is complete. If pretreatment is required, the mold can also be transferred to the pretreatment station by the kiln transfer trolley 42. After pretreatment, it is transferred to the curing kiln 4 for curing before entering the next production cycle.

[0038] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
