Dual-purpose portable closing machine of single-needle single-line and double-needles double-lines

Abstract

The invention discloses a dual-purpose portable closing machine of single-needle single-line and double-needles double-lines, which comprises a bearded needle mechanism, a feeding mechanism, a needle rod mechanism and a line passing mechanism, wherein a bearded needle frame, a left bearded needle, a right bearded needle, feeding teeth and a tooth frame are respectively and directly connected for transmission by a main shaft. According to the characteristics of the dual needles, the right bearded needle, the left bearded needle and drawing lines, the invention uses a method of the bearded needles travelling left and right to reach the stitches of single-needle single-line and double-needles double-lines, and keeps the function of single needle single line not affected. The invention can realize the single line stitch when a line is threaded, and realize the double line stitch when two lines are threaded. Two functions can be freely chosen to realize the function of one machine two purposes. The invention has the advantages of simple structure, reasonable distribution, stable performance and convenient operation, and can be widely used for closing pocket openings of gunnysacks, woven bags, paper-plastic compound bags contained goods in factories, wharfs, warehouses and the like.

Description

Technical field: [0001] The present invention relates to a single-needle, single-thread, double-needle, and double-thread function integrated sealing machine. The traditional sealing machine can only sew one row of single-thread stitches. The present invention can not only sew a row of single-thread stitches, but also can sew two rows of double-thread threads. It not only maintains the traditional single-needle and single-thread stitch, but also realizes double-needle and double-thread, double-layer protection new technology, one machine and two-purpose sealing machine. Background technique: [0002] The sewing stitches of the traditional sealing machine are single-thread chain, which is prone to jumping stitches and jumping threads to open the package and run away items. Because the single-needle and single-thread pitch is relatively large and small, powdery products are easy to leak out, especially the loss of valuables and export products is more serious. Users are not ha...

Problems solved by technology

[0003] In order to overcome the defect that the traditional single-needle and single-thread are easy to skip the thread and cause the goods to be opened and run, the single-needle and single-thread has a large needle pitch, and it is easy to leak out small particles and powdery products.

Adding thread slots on the panel, adding a group of crimping groups, adding a crimping group to cross the bridge, successfully integrating the mechanical structure of single needle single thread and double needle double thread into one body, realizing single needle single thread on the same body, Double-needle and double-thread function, as long as one thread is threaded for single-thread stitching, and two threads are threaded for double-thread stitching, which solves the defects that single-needle and single-thread are easy to skip threads, and single-needle and single-thread stitches are too large to easily leak items. It also improves the product grade and realizes one machine with two functions
