Description

Technical Field

[0001] This invention relates to the field of precast component molding technology, specifically to a precast component molding production line and its production method. Background Technology

[0002] Precast concrete components refer to assembled concrete components that have been manufactured before installation on the construction site. Their production lines typically employ a combination of human and machine methods for production operations.

[0003] For example, the announcement number CN113001741A is titled "A Precast Component Production Line." This production line includes a fixed mold table area, a transfer mold table area, and a curing area. The fixed mold table area is equipped with a work vehicle and at least two first work stations. The work vehicle performs at least one corresponding operation at each first work station and can move between different first work stations. The transfer mold table area is equipped with at least two second work stations. After processing at the first work stations, the work molds are transferred to the transfer mold table area and pass through several second work stations in sequence to form precast components to be formed. The curing area includes a curing kiln. After processing in the transfer mold table area, the work molds are transferred to the curing kiln to solidify the precast components to be formed into precast components. Finally, the work molds are transferred to the first work stations.

[0004] However, during production on the aforementioned production line, manual placement of the side molds on the side mold conveyor line at the workstation is required. Afterward, the molds are manually hoisted to the finished product buffer area. Once buffered, the molds are still manually disassembled, and the disassembled side molds are moved back to the side mold conveyor line. The entire process of mold placement, mold disassembly, and mold material transfer all require manual intervention, resulting in high labor costs and impacting production efficiency. Therefore, we propose a precast component molding production line and its production method to address the aforementioned problems. Summary of the Invention

[0022] Preferably, the demolding mechanism includes a third hydraulic cylinder, a reciprocating vibration mechanism, and a U-shaped support.

A connecting piece is installed at one end of the lifting rod, and the connecting piece is fixedly connected to the demolding mechanism. Four guide posts are arranged around the lifting rod.

[0024] Preferably, the production method of the precast component molding production line includes the following steps:

[0025] Step 1: When the production line is used for the first time, the integrated multi-position mold is transported from one end of the feeding conveyor to the bottom of the cloth feeding mechanism;

[0026] Step 2: The concrete pump truck pumps the material into the placing mechanism. The bottom of the placing mechanism is equipped with four feeding hoppers, which correspond to the four mold cavities in the integrated multi-position mold. During feeding, the electric valves below the four feeding hoppers release the material synchronously at timed intervals, quantitatively filling the four mold cavities with concrete raw materials. After completion, the first hydraulic cylinder drives the push plate to push the integrated multi-position mold to the vibrating roller table.

[0027] Step 3: After the integrated multi-position mold arrives at the vibrating roller table, it is sent to the scraper roller table by the first roller conveyor inside the roller table. During the process, the vibrating motor on the vibrating roller table runs, so that the material in the integrated multi-position mold is evenly distributed in the mold cavity under the action of vibration.

[0028] Step 4: After reaching the scraper roller table, the first electric guide rail on one side of the roller table drives the polytetrafluoroethylene scraper through the integrated multi-position mold in conjunction with the driven guide rail, scraping the excess material into the collection trough to achieve the leveling of the material in the mold. Then, the second roller conveyor in the scraper roller table sends the integrated multi-position mold into the drying chamber.

[0029] Step 5: After the batch of materials is dried in the drying room, it is transferred to the curing room for curing. After 24 hours, the curing room will gradually send out the integrated multi-position mold. When the integrated multi-position mold reaches the bottom of the demolding mechanism, the third hydraulic cylinder on the demolding mechanism will drive the U-shaped support to move down. The telescopic cylinders on both sides of the U-shaped support will extend, so that the flexible adsorption plate on the surface of the vacuum seat will adhere to the surface of the integrated multi-position mold. After being fixed by vacuum adsorption, the third hydraulic cylinder will retract. At the same time, the servo motor will drive the integrated multi-position mold to flip. After completion, the stepper motor will drive the reciprocating vibration mechanism to drive the integrated multi-position mold to vibrate up and down, and remove the preform from the mold cavity.

[0030] Step Six: After the precast components are removed, they are conveyed to the next step by the precast component conveyor. Meanwhile, the integrated multi-position mold moves laterally to the mold conveyor under the action of the guiding mechanism. It is then sequentially fed into the spray cleaning chamber and the drying pre-storage chamber by the mold conveyor. While the first batch of integrated multi-position molds is drying, the second batch of integrated multi-position molds is fed to the material feeding mechanism by the feeding conveyor. After the second batch of materials has finished drying, it is temporarily stored in the curing chamber. After the second batch of materials has finished curing, the integrated multi-position molds after the first batch of materials are removed are sent out from the drying pre-storage chamber and moved to the feeding conveyor for precast component production. The second batch of materials undergoes subsequent demolding. This process is repeated, and the two batches of integrated multi-position molds achieve a reciprocating production cycle.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. In operation, the production line of the present invention consists of a feeding conveyor, a vibrating roller table, a scraping roller table, a drying chamber, a curing chamber, a mold conveyor, a spray cleaning chamber, a drying pre-storage chamber, and a return material conveyor, all interconnected. During the production process, two batches of integrated multi-position molds can achieve reciprocating production cycles without the need for manual mold loading. Furthermore, the transfer process is completed by the conveying mechanism, which greatly reduces the manpower consumption of the production line. This solves the problem of existing production lines where manual placement of the side molds on the side mold conveyor line at the work station is required, followed by manual hoisting of the molds to the finished product buffer area, resulting in high manpower consumption.

[0033] 2. By setting up an automated demolding mechanism, the mold of this application adopts an integrated multi-position mold structure compared with conventional molds, which facilitates the demolding mechanism to grasp multiple molds at the same time. During demolding, the demolding mechanism drives the U-shaped support to move down under the driving action of the hydraulic mechanism, and uses the vacuum seat to generate negative pressure to adsorb the integrated multi-position mold. Then, under the flipping action of the servo motor, in conjunction with the reciprocating vibration mechanism, the preform can be removed from the mold cavity. After removal, the demolding mechanism can use the guiding mechanism to directly transfer the demolded mold to the mold conveyor, which solves the problem that the existing production line can only manually dismantle the mold one by one and manually move the demolded side mold to the side mold conveyor line, which is inefficient.

[0061] Please see Figure 1-7 A production method for a precast component molding production line includes the following steps:

[0062] Step 1: When the production line is used for the first time, the integrated multi-position mold 4 is transported from one end of the feeding conveyor 3 to the bottom of the cloth feeding mechanism 1;

[0063] Step 2: The concrete pump truck pumps the material into the placing mechanism 1. The bottom of the placing mechanism 1 is equipped with four feeding hoppers 22, which correspond to the four mold cavities 401 in the integrated multi-position mold 4. During feeding, the electric valves 23 below the four feeding hoppers 22 release the material synchronously at timed intervals, quantitatively filling the four mold cavities 401 with concrete raw materials. After completion, the first hydraulic cylinder 21 drives the push plate 26 to push the integrated multi-position mold 4 to the vibrating roller table 5.

[0064] Step 3: After the integrated multi-position mold 4 arrives at the vibrating roller table 5, it is sent to the scraper roller table 7 by the first roller conveyor 28 inside the roller table. During the process, the vibrating motor 40 on the vibrating roller table 5 runs, so that the material in the integrated multi-position mold 4 is evenly distributed in the mold cavity 401 under the action of vibration.

[0065] Step 4: After reaching the scraper roller table 7, the first electric guide rail 36 on one side of the roller table drives the polytetrafluoroethylene scraper 39 through the integrated multi-position mold 4 in conjunction with the driven guide rail 37, scraping the excess material into the collection trough 6 to achieve leveling of the material in the mold. Then, the second roller conveyor 35 in the scraper roller table 7 sends the integrated multi-position mold 4 into the drying chamber 8.

[0066] Step 5: After drying in drying chamber 8, the batch of materials is transferred to curing chamber 9 for curing. After 24 hours, curing chamber 9 gradually sends out the integrated multi-position mold 4. When the integrated multi-position mold 4 reaches below the demolding mechanism 12, the third hydraulic cylinder 43 on the demolding mechanism 12 is driven to move the U-shaped support 48 down. The telescopic cylinders 49 on both sides of the U-shaped support 48 extend, so that the flexible adsorption plate 52 on the surface of the vacuum seat 51 adheres to the surface of the integrated multi-position mold 4. After being fixed by vacuum adsorption, the third hydraulic cylinder 43 retracts. At the same time, the servo motor 50 is driven to rotate the integrated multi-position mold 4. After completion, the stepper motor 46 is driven to make the reciprocating vibration mechanism 45 drive the integrated multi-position mold 4 to vibrate up and down, and remove the preform from the mold cavity 401.

[0067] Step Six: After the precast parts are removed, they are conveyed to the next step by the precast part conveyor 10. Meanwhile, the integrated multi-position mold 4 moves laterally to the mold conveyor 13 under the action of the guide mechanism 11.

While the first batch of integrated multi-position molds 4 is drying, the feeding conveyor 3 feeds the second batch of integrated multi-position molds 4 to the material feeding mechanism 1. After the second batch of materials has finished drying, it is temporarily stored in the curing chamber 9. After the second batch of materials has finished curing, the integrated multi-position molds 4 after the first batch of materials is removed are sent out from the drying pre-storage chamber 15 and moved to the feeding conveyor 3 for precast part production.
