A sewing thread automatic packaging machine

Abstract

The invention discloses a full-automatic sewing thread packaging machine. The full-automatic sewing thread packaging machine comprises a control system, a machine frame, a conveying device, a contracting device, a conveying belt, a labeling device and a bagging device, wherein the conveying device, the contracting device and the conveying belt are all arranged on the machine frame, and the labeling device and the bagging device are sequentially arranged on the conveying belt. The control system comprises a main control circuit board, a first isolating circuit and a second isolating circuit, wherein the main control circuit board is coupled to an external manipulator and an external sensor to receive an induction signal output by the sensor and send out a driving signal to the manipulator so as to drive the manipulator to act; the first isolating circuit is coupled between the main control circuit board and the external manipulator to electrically isolate the communication between the main control circuit board and the external manipulator; and the second isolating circuit is coupled between the main control circuit board and the external sensor to electrically isolate the communication between the main control circuit board and the external sensor. According to the full-automatic sewing thread packaging machine, through the arrangement of the first isolating circuit and the second isolating circuit, the connection between the manipulator and the main control circuit board as well as between the sensor and the main control circuit board can be effectively isolated.

Description

technical field [0001] The present invention relates to a packaging equipment, more particularly to a sewing thread automatic packaging machine. Background technique [0002] At present, the packaging of sewing thread in my country is mainly in the form of pure manual work. This traditional packaging method requires a lot of labor to complete, which restricts the development and transformation of the sewing thread industry that has been occupying the market with low prices and low profits for a long time. On the other hand, this inefficient manual packaging method is difficult to adapt to the requirements of mass production of modern commodities. At the same time, the packaging quality of manual packaging is unstable and the consistency is poor, which can no longer meet the quality requirements of consumers for packaging. It is very necessary to provide an automatic sewing thread packaging machine. Existing foreign automatic packaging machines are widely used. Computer desi...

At the same time, it has an automatic identification function for the packaging material and thickness, and then controls the mechanical action after calculation by the computer. It is a completely "adaptive" system to ensure that the system works in an optimal state. However, the main circuits of these existing electrical systems are integrated in the On a control board, the relationship between its various parts is very close. When a branch circuit in the main circuit fails, it will cause the entire main circuit to be paralyzed, which will seriously affect the operation of the packaging machine. In the process of fault detection, it is difficult to detect which branch of the main circuit is faulty, which brings trouble to maintenance
