Description

Technical Field

[0001] This utility model relates to the technical field of sintered brick production equipment, and in particular to an automatic anti-tipping net laying machine. Background Technology

[0002] A tunnel kiln is a modern, automated thermal kiln constructed from refractory, insulation, and building materials. It resembles a tunnel and contains kiln cars and other transport vehicles. Before producing red bricks (high-temperature sintered brick blanks) in a tunnel kiln, the brick blanks need to be stacked. To prevent the stacked brick blanks from tipping over due to shrinkage during drying, an anti-tipping net is laid on top of them to provide some tension and prevent tipping. For example, an anti-tipping net can be laid on the third layer of brick blanks from the top.

[0003] Traditionally, the installation of anti-tipping netting has been done manually, which is inefficient and prone to accidents such as accidental collisions with automatic stacking machinery. Although some semi-automatic netting machines exist, these machines still require manual cutting and reinstallation of the netting after installation, making the installation efficiency less than satisfactory and failing to achieve manual-free operation.

[0004] Therefore, how to provide an automatic anti-tilting net laying machine to improve the efficiency and safety of anti-tilting net laying has become an urgent technical problem to be solved. Utility Model Content

[0047] 1. The system comprises a net-laying mechanism, a net-cutting mechanism, a net-laying mechanism, a net-hooking mechanism, and a PLC. The net-cutting mechanism is mounted on the net-laying mechanism, while the net-laying and net-hooking mechanisms are located at the beginning and end of the net-laying mechanism's stroke, respectively. The PLC is connected to each of the net-laying, net-cutting, net-laying, and net-hooking mechanisms. The anti-tipping net to be laid is placed on the rollers of the net-laying mechanism, with the starting end of the anti-tipping net laid on the net-laying frame of the net-laying mechanism. When the anti-tipping net needs to be laid, the PLC controls the net-laying mechanism. The first cylinder presses the anti-tipping net tightly onto the pressing rod, then drives the crossbeam of the net laying mechanism to move horizontally, synchronously driving the roller to rotate to release the net, thereby pulling and laying the anti-tipping net. When the crossbeam moves into position, the anti-tipping net is hooked by the hooking mechanism and stretched, controlling the net laying mechanism to reset, and then the anti-tipping net is heated and cut by the heating wire of the cutting mechanism. This realizes the automatic laying and cutting of the anti-tipping net without manual intervention, thus greatly improving the efficiency and safety of the anti-tipping net laying.

[0048] 2. By setting up a remote control, which connects to the PLC through the second and first wireless communication modules, the net laying machine can be remotely controlled, greatly improving the convenience of operation and further enhancing the safety of anti-falling net laying.

[0049] 3. When the anti-tipping net is pulled by the net laying mechanism, the second servo motor synchronously drives the roller to rotate to perform the net laying operation, which avoids the anti-tipping net being deformed or damaged due to brute force pulled by the net laying mechanism, thereby greatly improving the quality of anti-tipping net laying.

[0050] 4. By setting up a cutting mechanism including a lifting mechanism, heating wire, transformer, and temperature sensor, the transformer adjusts the current flowing through the heating wire to control the heating wire's temperature rise. The temperature sensor monitors the temperature of the heating wire in real time. When the temperature of the heating wire reaches the required cutting temperature, the lifting mechanism lowers the heating wire to contact the anti-tipping net for heating and cutting. Compared with the traditional method of using a cutting blade, this method avoids the anti-tipping net collapsing due to resistance during the cutting process, further improving the quality of anti-tipping net laying in tunnel kilns.

[0101] Working principle of this utility model:

[0102] The starting end of the anti-tipping net 9 is laid on the net laying frame 16 of the net laying mechanism 1. Based on the trigger signal of the remote controller 7, the PLC 5 controls the first cylinder 17 of the net laying mechanism 1 to press the anti-tipping net 9 onto the pressing rod 15. Then, the first servo motor 14 drives the crossbeam 13 of the net laying mechanism 1 to make horizontal displacement, so as to move the pressing rod 15 in conjunction with it, thereby pulling the anti-tipping net 9.

[0104] The PLC5 controls the net laying mechanism 1 to reset, and then adjusts the current flowing through the heating wire 22 through the transformer 23 to control the heating wire 22 to heat up. The temperature sensor 24 monitors the temperature of the heating wire 22 in real time. 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-tipping net 9, so as to heat and cut the anti-tipping net 9, thereby completing the laying of the anti-tipping net 9.

[0105] In summary, the advantages of this utility model are as follows:

[0106] 1. The system comprises a net-laying mechanism, a net-cutting mechanism, a net-laying mechanism, a net-hooking mechanism, and a PLC.

The PLC is connected to each of the net-laying, net-cutting, net-laying, and net-hooking mechanisms. The anti-tipping net to be laid is placed on the rollers of the net-laying mechanism, with the starting end of the anti-tipping net laid on the net-laying frame of the net-laying mechanism.

This realizes the automatic laying and cutting of the anti-tipping net without manual intervention, thus greatly improving the efficiency and safety of the anti-tipping net laying.
