Description

Technical Field

[0001] The invention relates to the technical field of sintered brick production equipment, in particular to an automatic net laying machine to prevent net collapse. Background Art

[0002] The tunnel kiln is a tunnel-like kiln built with refractory materials, thermal insulation materials and building materials. It is equipped with kiln cars and other vehicles. It is a modern thermal equipment for assembly line sintering. Before using the tunnel kiln to produce red bricks (high-temperature sintered bricks), the bricks need to be stacked and placed. In order to prevent the bricks stacked in several layers from falling due to shrinkage during the drying process, a layer of anti-falling net needs to be laid on the bricks to form a certain pulling effect on the bricks to prevent them from falling. For example, a layer of anti-falling net is laid on the third layer of bricks from the top.

[0003] Traditionally, the laying of anti-falling nets is done manually, which has the disadvantage of low efficiency. In addition, during the manual laying process, the nets may collide with the automatic blanking machine accidentally, which may cause casualties. Although there are some semi-automatic net laying machines on the market, these semi-automatic net laying machines still require manual cutting and reinstallation of the anti-falling nets after laying, which makes the laying efficiency unsatisfactory and cannot be done without manual operation.

[0004] Therefore, how to provide an automatic anti-falling net laying machine to improve the efficiency and safety of anti-falling net laying has become a technical problem that needs to be solved urgently. Summary of the invention

[0101] Working principle of the present invention:

[0102] The starting end of the anti-falling net 9 is laid on the net laying frame 16 of the net laying mechanism 1. The PLC5 controls the first cylinder 17 of the net laying mechanism 1 to press the anti-falling net 9 onto the net pressing rod 15 based on the trigger signal of the remote control 7. Then, the first servo motor 14 drives the crossbeam 13 of the net laying mechanism 1 to move horizontally to link the net pressing rod 15 to move, thereby pulling the anti-falling net 9.

When the temperature of the heating wire 22 reaches the temperature required for cutting, the lifting mechanism 21 is controlled to lower the heating wire 22 to contact the anti-falling net 9, so as to heat and cut the anti-falling net 9, thereby completing the laying of the anti-falling net 9.

[0105] In summary, the advantages of the present invention are:

When the crossbeam moves into place, the anti-falling net is hooked and stretched by the net hooking mechanism, and the net laying mechanism is controlled to reset, and then the anti-falling net is heated and cut by the heating wire of the net cutting mechanism, thereby realizing automatic laying and cutting of the anti-falling net without human intervention, thereby greatly improving the efficiency and safety of laying the anti-falling net.

[0107] 2. By setting up a remote control, the remote control is connected to the PLC through the second wireless communication module and the first wireless communication module, that is, the net laying machine can be remotely controlled to operate through the remote control, which greatly improves the convenience of operating the net laying machine and further improves the safety of anti-falling net laying.

[0108] 3. When the net laying mechanism is set to pull the anti-falling net, the second servo motor synchronously drives the drum to rotate to release the net, so as to avoid the net laying mechanism pulling the anti-falling net by brute force, which may cause deformation or damage of the anti-falling net, thereby greatly improving the quality of the anti-falling net laying.

[0109] 4. A mesh cutting mechanism including a lifting mechanism, a heating wire, a transformer and a temperature sensor is provided. The current flowing through the heating wire is adjusted by the transformer to control the heating wire to heat up.
