Description

Technical Field

[0001] This utility model relates to the technical field of yarn breakage early warning devices for textile machines, and in particular to a yarn breakage early warning device for textile machines. Background Technology

[0002] Existing textile machines occasionally experience yarn breakage during the weaving process. If workers cannot detect and adjust the breakage in time, it can lead to defects in the woven products and economic losses. Existing yarn breakage devices consume a lot of energy and have limited sensitivity.

[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0004] A yarn breakage early warning device for a textile machine includes a pulley frame, within which a yarn guide wheel is rotatably mounted. The yarn passes around the yarn guide wheel. A power supply battery and an early warning buzzer are fixedly mounted on the pulley frame. The power supply battery supplies power to the early warning buzzer to trigger an alarm. A sliding groove is provided within the pulley frame, and a sliding bearing seat is slidably mounted within the groove. The shaft of the yarn guide wheel is inserted into the inner ring of a bearing within the sliding bearing seat. The sliding bearing seat moves up and down, changing the height of the rotation axis of the yarn guide wheel. The bottom of the sliding bearing seat... A counter-pull rod is fixedly provided in the part, and a limit circuit breaker is also fixedly provided in the pulley frame. The counter-pull rod passes through the limit circuit breaker. A spring is arranged between the sliding bearing seat and the limit circuit breaker. The power supply battery pack, the warning buzzer, the limit circuit breaker and the wires form a power supply circuit, and the limit circuit breaker has a break point in the power supply circuit. A conductive component is fixedly provided at the lower end of the counter-pull rod. When the yarn wound on the yarn guide wheel breaks, the downward pressure applied to the spring disappears, and the conductive component at the lower end of the counter-pull rod connects the break point at the limit circuit breaker, causing the warning buzzer to sound an alarm.

[0005] Preferably, the conductive plate is fixedly provided with two protruding conductive contacts, which respectively contact the conductive parts on both sides of the break point on the limit circuit breaker.

[0006] Preferably, the conductive contact is a copper contact and is zinc-plated on its outer surface.

[0007] Preferably, an arc-shaped fastening groove is provided at the bottom of the pulley frame, and at least one fastening bolt is provided in cooperation with the arc-shaped fastening groove. The fastening bolt passes through the arc-shaped fastening groove to fix the pulley frame in a designated position, and the inclination of the pulley frame can be adjusted to accommodate different working positions.

[0008] Preferably, the anti-pull rod does not contact the limit circuit breaker, and the opening in the limit circuit breaker through which the anti-pull rod passes is larger than the diameter of the anti-pull rod.

[0009] Preferably, the power supply battery pack is a rechargeable lithium battery.

[0010] The advantages and positive effects of this utility model are:

[0011] 1. The reverse trigger design does not consume power during normal operation. When the textile yarn breaks, the power supply to the warning buzzer is closed through the conductive component, thereby triggering the alarm. This allows workers to discover the problem in time, effectively assisting production. The structure is also compact and easy to use. Attached Figure Description
