Description

TECHNICAL FIELD

[0001] The application relates to the technical field of temperature reduction, in particular to a temperature reduction mechanism of an electric heating wire foam board cutting machine. BACKGROUND

[0002] The temperature reduction mechanism of the electric heating wire foam board cutting machine is a device for reducing the temperature of the electric heating wire for cutting the foam board, which can prevent the electric heating wire from affecting the cutting effect and shortening the service life due to the excessively high temperature.

[0003] However, the current means for reducing the temperature of the electric heating wire is very limited and inefficient, and mostly relies on natural cooling or wind blowing. It takes a long time for the electric heating wire to reduce from a high temperature to a cool state that can be operated, and the subsequent process can only be forced to stop for a long time to wait, which greatly slows down the overall production rhythm and causes a waste of a large amount of time and labor cost. Meanwhile, the long cooling process can also cause thermal damage to the surrounding equipment due to heat accumulation, shorten the service life of the equipment and increase the maintenance cost.

[0004] In view of this, the application provides the temperature reduction mechanism of the electric heating wire foam board cutting machine. CONTENT OF THE INVENTION

[0007] Optionally, a clamping plate is arranged above the metal plate, clamping grooves are formed in the end surfaces of the clamping plate and the metal plate that are close to each other, and a hand holding block is fixedly connected to the upper end surface of the clamping plate.

[0008] Optionally, the outer wall of the mounting frame is symmetrically fixedly connected with a fixed plate, a first sliding groove is formed in the inside of the fixed plate on one side, and a second sliding groove is formed in the upper end surface of the fixed plate on the other side.

[0010] Optionally, both ends of the limiting rod are fixedly connected with the first sliding groove, and a spring is sleeved below the outer wall of the limiting rod.

[0011] Optionally, an extension block is arranged in the second sliding groove and fixedly connected with the clamping plate, and a rotating knob is threadedly connected in the extension block.

[0012] One or more technical solutions provided in the technical scheme have at least the following technical effects or advantages:

[0013] 1. The application accurately and stably clamps the heating wire through the clamping groove between the metal plate and the clamping plate, and realizes efficient conduction of cold energy by the combination of the semiconductor refrigerating sheet and the metal plate. The refrigerating surface of the semiconductor refrigerating sheet rapidly cools, and the cold energy can be quickly transferred to the metal plate, thereby providing strong cooling capacity for the heating wire, greatly shortening the time interval of the heating wire from high temperature to cooling, ensuring that the subsequent process can be carried out in time, reducing the time waste caused by waiting for cooling, and improving the overall production rhythm.
