Automatic tying equipment for woven bags

Abstract

An automatic tying device for woven bags comprises a long needle threading mechanism, a thread outlet mechanism, a thread shifting and opening and closing mechanism, a short needle threading mechanism, a transverse tightening mechanism and a bottom plate. A long needle threading device of the long needle threading mechanism is installed at one end of the bottom plate in a sliding mode, the thread outlet mechanism is movably installed at the other end of the bottom plate, the thread shifting and opening and closing mechanism is movably installed in the middle of the bottom plate, the short needle threading mechanisms are movably installed on the two sides of the bottom plate, and the transverse tightening mechanism is movably installed on a long plate of each short needle threading mechanism. The long needle threading mechanism is used for carrying out thread lapping and transverse needle threading tying on the short needle threading mechanism, the thread outlet mechanism is used for storing threads and carrying out thread lapping on the short needle threading mechanism, and the thread shifting and opening and closing mechanism is used for shifting the threads after the threads are lapped on the short needle threading mechanism, so that the threads between short needles have enough length; meanwhile, the thread shifting and opening and closing mechanism is further used for enabling the short needle threading mechanism to be integrally meshed, the short needle threading mechanism is used for longitudinally threading needles and tying openings, and the transverse tightening mechanism is used for shortening the distance between the short needles, so that the tying openings are tighter.

Description

technical field [0001] The invention relates to the field of packaging equipment, in particular to an automatic tying device for woven bags. Background technique [0002] Most of the commonly used banding machines are in the form of manual operation. People need to manually hold the mouth of the packaging bag into a bundle and place it on the muzzle of the banding machine. Obviously, it is not suitable for the needs of industrial automation production. Therefore, an automatic knitting device for woven bags is needed. This equipment does not need to manually arrange the bag mouth, and can automatically complete the knitting work throughout the process. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention provides an automatic tying device for woven bags, which greatly improves work efficiency and saves time. [0004] The technical scheme used in the present invention is: an automatic tying device for a woven bag, comprising a long needle t...

[0002] Most of the commonly used binding machines are manually operated, requiring people to manually hold the mouth of the packaging bag into a bundle and place it on the muzzle of the binding machine. It is obviously not suitable for the needs of industrial automatic production, so an automatic tying equipment for woven bags is needed. This equipment does not need to manually arrange the bag mouth, and can complete the tying work automatically in the whole process.
