An automatic cleaning system for detonating cord cutting thermal knives

Abstract

The invention relates to an automatic cleaning system for detonating cord cutting heat tools. The cleaning system comprises a main controller, an attachment gasification removing module, a black spotdetecting device and an air extraction device. The attachment gasification removing module comprises a temperature controller, a thermal resistor, a hot melting blade and a temperature sensor; the black spot detecting device connected with the main controller detects the area of black spots formed by attachments on the hot melting blade, and transmits detected black spot area signals to the main controller; a set value is set in the main controller; when the black spot area signals received by the main controller reach the set value, the main controller defines constraints to the temperature controller, and controls the thermal resistor to heat the hot melting blade, so that the attachments are gasified to be cleaned in a short time; after the area of the black spots is zero, the main controller controls the air extraction device to be opened, and accordingly, rapid, safe and automatic cleaning is realized. The automatic cleaning system has the advantages of high cleaning speed, good effect, high efficiency, and safety and reliability in operation.

Description

[0001] The invention belongs to the field of aerospace pyrotechnics production, in particular to an automatic cleaning system for detonating cord cutting thermal knives. Background technique [0002] The detonating cord is a kind of linear pyrotechnic product with certain flexibility, which plays an irreplaceable role in national defense and military construction projects. The processing of the detonating cord mainly includes steps such as cutting, separating the cladding layer, and crimping. Directly cutting the detonating cord by mechanical means will cause the braided layer of the cut surface of the detonating cord to be scattered, which will affect the subsequent process of removing the cladding layer at the end. , so the method of first heating to fuse the detonating cord coating layer, and then mechanically cutting along the detonating cord cutting part. But when heating and fusing the cladding layer of detonating cord, the cladding layer material will be attached to the...

AI Technical Summary

Problems solved by technology

[0003] (1) The method of workers using razors to remove attachments on hot melt knives is a waste of manpower and material resources, a waste of time, and reduces the production efficiency of the entire processing link. At the same time, there are certain safety hazards

[0004] (2) Workers use a razor to remove the attachments on the hot-melt knife, which is easy to cause damage to the surface of the hot-melt knife, affecting its life, and will also affect the temperature control, thereby affecting normal production and processing
