Working mode and structure of thread shearing machine

Abstract

The invention discloses a working mode and a structure of a thread shearing machine which is easy to install and maintain and reduces cost and manpower. The working mode comprises the following steps of: turning on a travel switch to switch on a power supply of a controller to start electric shears to work, controlling an electromagnetic pump and an electromagnetic valve 2 to spray oil for 0.01 to 0.03 second through the controller, then delaying the time for 0.1 second, and circularly starting the electromagnetic pump and the electromagnetic valve to spray oil for at least 2 times; delaying the time for 1 to 3 seconds through the controller after oil spraying is finished, and starting a dust collecting motor to collect garbage; turning off the travel switch to stop the electric shears and the dust collecting motor; and pressing a refueling switch in the working process, stopping the work of the dust collecting motor through the controller, starting the electromagnetic pump and the electromagnetic valve to spray oil, loosening the refueling switch, then closing the electromagnetic pump and the electromagnetic valve to stop spraying oil through the controller, delaying the time for 0.5 to 1 second, and starting the dust collecting motor to collect garbage. The working mode is mainly applied to dress processing machinery.

Description

technical field [0001] The invention relates to a garment processing device, in particular to a working mode and structure of a thread trimmer. Background technique [0002] In the garment processing industry, various thread ends are usually left on the processed clothes, and at this time, workers are required to use scissors to cut off the thread ends. With the increasingly intensified economic competition, cutting off the thread ends manually not only wastes time but also greatly reduces efficiency and reduces the competitiveness of enterprises. Some factories use thread trimmers, which can quickly and conveniently cut off the remaining thread ends on clothes, and collect the cut thread ends in containers, reducing the trouble of cleaning. However, the existing thread trimmers usually have a short service life. After a long time of use, the thread trimmer head will be dry-grinded due to lack of lubricating oil, which further shortens the life of the cutter head, and its c...

However, the existing thread trimmers usually have a short service life. After a long time of use, the thread trimmer head will be dry-grinded due to lack of lubricating oil, which further shortens the life of the cutter head, and its cost is expensive, and the wiring is complicated. Adjusting the fuel injection time and fuel injection volume, the control method is cumbersome, low precision and easy to waste, the fuel injection volume is difficult to control, and the large oil output is easy to pollute the product. If the oil output is small, the cutter head will wear more
