Description

However, in actual production, the production line is affected by various factors, and there is often a problem of empty space entering the kiln. To solve this problem, a blank storage rack is usually set at the kiln head, and the blanks on the blank storage rack are used to make up for the empty space of the production line to ensure that the kiln is not empty. However, the conventional blank storage rack layout is embedded in the middle of the roller rod of the roller table, and is nested with the roller table. The blank storage rack cannot be moved out without removing the roller rod. If the green blanks on the blank storage rack are stored for a long time, they will become very fragile and easy to deform. In this way, it is easy to break when the storage rack is moved up and down and the roller table is transported forward and backward. Once broken, the green blank fragments are easily blocked in the gaps between the roller rod and the blank storage rack, which is difficult to handle. The roller rod needs to be removed to handle the broken blanks. The processing time is long, the workload is large, and the risk is high, which can easily cause the kiln to be empty.

[0060] Please refer to Figures 1 to 5 In the second embodiment of the present application, a kiln ceramic brick blank feeding control method is provided. The kiln ceramic brick blank feeding control method is implemented based on the ceramic brick firing production line provided in the second embodiment of the present application. The kiln ceramic brick blank feeding control method includes:

[0062] Step S12, start the brick storage lifting assembly, control the spare brick storage roller platform among the plurality of brick storage roller platforms to be flush with the front roller platform, wherein the spare brick storage roller platform is the brick storage roller platform among the plurality of brick storage roller platforms storing spare brick blanks;

[0063] Step S13, synchronously start the front roller table and the brick feeding transmission assembly, and transfer the spare brick blanks to the lower movable roller table through the brick feeding transmission assembly; the front roller table transfers the new brick blanks to the spare brick storage roller platform.

[0064] Specifically, the hydraulic station is controlled to control the lifting of the hydraulic support, and then a spare brick storage roller platform among several brick storage mechanisms is controlled to be flush with the front roller platform. The spare bricks carried on the spare brick storage roller platform are transported to the brick receiving mechanism through the brick feeding transmission assembly, so as to avoid empty kilns.
