Abstract

A weft breakage detection device with a function of simple setting comprises a sensing source, a sensing unit and a micro-processing unit. The sensing source is mounted on a yarn guide bar of a shuttle and capable of swinging along with the yarn guide rod. The sensing unit comprises at least two sensors disposed at intervals. The sensors are used for respectively sensing the sensing source to generate corresponding signal values. The micro-processing unit is electrically connected with the sensors and capable of receiving the signal values for processing and determination. Therefore, the sensors can be used for automatically sensing the sensing source on the yarn guide bar and transmitting the sensed signal values to the micro-processing unit for determination so as to control the shuttle to stop, the effect of quick and simple setting is achieved, and the time consumed by an operator to make settings is reduced.

Description

technical field

[0001] The invention relates to a weft yarn break detection device with simple setting function, which can control the shuttle to stop when the weft yarn breaks, so as to prevent defective products from being produced. Background technique

[0002] By the way, most of the lightweight and cheap packaging bags used by ordinary people in daily life are mainly made of PE and PP woven bags, and they are usually made of different sizes of packaging bags by mechanical weaving. Among the machines, the circular knitting machine has many advantages such as fast production, stable quality and convenient use, so it has become the main machine for the industry to make cloth for packaging bags.

[0003] However, the traditional circular knitting machine not only produces empty weft phenomenon due to thread breakage, but also produces empty weft phenomenon when the weft yarn is exhausted. Therefore, as long as the operator fails to detect in time and control the shuttle boa...

Embodiment Construction

[0022] First, see figure 1 and figure 2 Shown is the schematic diagram of the present invention in the unbroken state of the weft yarn and the schematic diagram of the broken state of the weft yarn; the present invention includes:

[0023] An induction source 10, in the embodiment of the present invention, the induction source 10 is a permanent magnet, and is installed on a yarn-drawing bar 101 of a shuttle boat 100, and can move with the deflection of the yarn-drawing bar 101, and In the present invention, the shuttle boat 100 is respectively provided with a weft yarn guide rod 102 and a weft yarn bobbin 103, and the weft yarn guide rod 101 can swing between the weft yarn guide rod 102 and the weft yarn bobbin 103, and generally has a first state And a second state, and the first state is the position where the yarn drawing rod 101 is close to the weft yarn guide rod 102 (that is, the yarn drawing rod 101 is pulled by the weft yarn 1031 on the weft yarn bobbin 103), the Th...
