Description

Technical Field

[0001] This invention relates to the field of concrete precast component production equipment technology, specifically a fully automatic concrete precast component coating machine. Background Technology

[0002] Currently, a step in the production of precast concrete components involves covering the surface of the poured components with a thin film. This film isolates the components from air, reduces surface moisture evaporation, maintains stable internal moisture levels, promotes cement hydration, accelerates concrete strength development, and reduces the frequency of manual watering, thus lowering costs. Therefore, film covering after pouring precast concrete components has become an indispensable part of the process. Currently, this film covering relies on manual labor, requiring at least two people. Consequently, the film covering process in precast concrete component production has consistently suffered from high labor costs, high labor intensity, and low production efficiency. Furthermore, manual operation increases the probability of various risks.

[0003] Therefore, a fully automatic precast concrete component coating machine is needed. Summary of the Invention

[0028] In at least one embodiment, the slide rail fixing bracket 4-6 is fixedly connected to the pressure film assembly fixing beam 2-3 by fasteners.

[0029] The overall working principle of this invention is as follows: After the concrete component is poured, it is transported to the laminating machine via the production line's support wheel transportation system. Upon receiving the component's arrival signal from the sensor on the laminating machine, it sends a component arrival signal to the laminating machine's PLC. The PLC receives the signal and issues a command for the laminating machine trolley 2 to move to its initial position. Upon receiving the arrival signal of the laminating machine trolley 2, the PLC sends a signal, causing the cylinder 6-10 of the pressing assembly 6 to move downwards. The pressing roller 6-9 presses the film onto the surface of the precast component. After the cylinder 6-10 of the pressing assembly 6 reaches its position, it sends a signal. Upon receiving the arrival signal of the pressing assembly 6, the PLC sends a signal to the laminating machine trolley 2, causing the laminating machine trolley 2 to move forward, driving the film roll hanger 3 forward. The film roll 3-6 rotates, carrying the film. After the laminating machine trolley 2 reaches its position, it sends a signal to the PLC. Upon receiving the arrival signal from the laminating machine trolley 2, the cylinder 4-17 of the film clamping assembly 4 moves downward, and the pressure roller 4-1 presses the film onto the surface of the component. After the pressure roller 4-1 reaches its position, it sends a signal. Upon receiving the arrival signal from the pressure roller 4-1, the PLC sends a signal to the fusing system 5. The fusing system 5 moves downward through the cylinder 5-8. The heating wire 5-6 starts heating as soon as the equipment starts running. The heating wire 5-6 melts the film on the component through the high temperature. After the film melts, it sends a signal. Upon receiving the signal, the PLC sends a signal to the film clamping assembly 4, the fusing system 5, and the pressure assembly 6 to rise through their respective cylinder components. After the film clamping assembly 4, the fusing system 5, and the pressure assembly 6 reach their positions, they send a signal. Upon receiving the position signal, the PLC sends a signal, and the laminating machine trolley 2 moves backward to the initial position, thus completing one laminating operation of the precast component.

[0030] The embodiments described in this invention are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the scope of protection of this invention.
