Yarn breakage trigger device

Abstract

The invention belongs to the technical field of mechanical equipment for the production of rayon. A yarn breakage trigger device is arranged between a winding drum and a bobbin which are connected with a power supply, and yarn is stretched between the winding drum and the bobbin. The yarn breakage trigger device comprises a trigger box and a hanging ring, a magnetic member is arranged on the top of the inside of the trigger box, and a magnet is disposed at the bottom of the trigger box; the upper end of the hanging ring is fixed onto a connecting rod which is connected with a tension spring, and the tension spring is inserted into the trigger box to be connected with the magnet; the rod body of the connecting rod is provided with an L-shaped impacting rod which is connected with a knife switch of the power supply. According to the yarn breakage trigger device, the trigger device is arranged on the stretched yarn for detecting the yarn breakage. The yarn breakage trigger device is simple in structure and can cut off the power supply timely to prevent production loss.

Description

Technical field [0001] The invention belongs to the technical field of mechanical equipment for manufacturing rayon. Background technique [0002] A common problem in yarn manufacturing is that the yarn is easily broken after the reel and the bobbin are stretched. The yarn breakage causes the spinning process to stop and it is difficult to maintain process continuity. In order to overcome this problem, it has been found that all Both the reel and the thread reel are driven at the same speed. The disadvantage of the above solution is that although there are additional measures to prevent yarn breakage, there is no alarm trigger device when the yarn is actually broken. At present, workers monitor the yarn spinning situation with the naked eye. This is labor-intensive. If the yarn breaks and the workers are not aware of it, the power supply cannot be cut off in time, causing production losses. Summary of the invention [0003] The present invention intends to provide a yarn break t...

Problems solved by technology

[0002] A common problem in yarn manufacturing is that the yarn is easy to break after the reel and the bobbin are straightened, and the yarn breakage causes the stop of the spinning process and it is difficult to maintain the continuity of the process. In order to overcome this problem, it has been found that all Yes spool and spool are driven at the same speed

The disadvantage of the above scheme is that although the measures for preventing yarn breakage are added, there is no alarm trigger device when the yarn is actually broken. If the yarn is broken and the workers are not aware of it, it will not be possible to cut off the power in time, resulting in loss of production
