When the preset height is about to be reached, the height sensor transmits a signal to the controller, and the controller controls the slurry injection equipment to reduce the slurry injection amount; when the preset height is reached, the height sensor transmits a signal to the controller, and the controller controls the slurry injection equipment to stop slurry injection.
Example 3.3
The utility model provides a mould for preparing luminous brick, on the basis of embodiment 1 or 3.1 or 3.2's mould, the mould still sets up the worker that is used for arranging luminescent fiber and draws the frame, the worker draws the die block looks adaptation of frame and mould. The specific adaptation mode can be seen in the Chinese patent application with the publication number of CN 107915443A.
Example 3.4
On the basis of the embodiment, an upper cover which can just move up and down in a main structure of the die can be arranged, and the shape and the size of the upper cover are matched with the internal structure of the die. Thus, when the total thickness of the brick is less than the thickness of the mould, the surface of the brick can still be flat by moving the upper cover up and down.
When the height of the mould is exactly the same as the height of the brick, the upper cover can also be arranged to match with the edge of the top of the mould which protrudes to the periphery.
Example 3.5
A mold for manufacturing a light emitting brick, which is different from embodiment 1, as shown in fig. 3, the mold of this embodiment is provided with scale marks 2 on both sides of the main structure of the mold.
Example 3.6
A mold for manufacturing a light-emitting brick, which is different from embodiment 1 in that scale marks 2 are arranged on three sides of a main structure of the mold.
Example 3.7
A mold for manufacturing a light-emitting brick, which is different from embodiment 1 in that scale marks 2 are arranged on four sides of a main structure of the mold.
It should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
Claims (6)
