Description

Technical Field

[0001] The utility model relates to an automated mechanical device, more specifically, to a double-head automatic rubber band connecting machine. Background Art

[0002] Clothing material manufacturing equipment refers to equipment that manufactures and cuts clothing materials through automated components. Highly automated clothing material manufacturing equipment can improve clothing material manufacturing efficiency. There are many types of clothing material manufacturing equipment on the market.

[0003] Currently, the automatic rubber band splicing machine on the market includes a frame, a cutter mounted on the frame, and a feeder mounted on the frame. Traditional automatic rubber band splicing machines convey and cut rubber bands, but the traditional method is relatively complicated to operate. Single-head automatic rubber band splicing machines can directly connect to the rubber band output end, but to increase efficiency, double-head automatic rubber band splicing machines are generally used. However, with a double-head rubber band splicing machine, the rubber band needs to switch back and forth between the left and right output signals. If the switching is not timely, the rubber band output will be chaotic, making operation difficult. At the same time, because the rubber band output part is one, when it is connected to the double-head rubber band splicing machine, it will cause unstable conveying and inconsistent cutting lengths, resulting in low production and processing efficiency.
