Abstract
The utility model belongs to the technical field of sewing machines and particularly relates to a lockstitch sewing machine with large winding quantity, wherein the inner diameter of a shuttle core and the height of the lockstitch sewing machine are increased. The lockstitch sewing machine with the large winding quantity comprises a rotation shuttle device on the lower side of a needle plate of the lockstitch sewing machine. The rotation shuttle device comprises an outer shuttle and an inner shuttle which supports the outer shuttle to rotate. A line cutting device is arranged above the rotation shuttle device. A shuttle core is installed in the inner shuttle of the rotation shuttle device. The outer diameter of the shuttle core is 25mm and the height of the shuttle core is 10mm. After the shuttle core is improved, the winding quantity of the shuttle core is improved, the shuttle core is not frequently replaced in an operation process and then winding is renewed. Production efficiency is improved.
Description
Technical field
The utility model belongs to the sewing machine technique field, refers in particular to a kind of shuttle internal diameter and the large flat seam machine of coiling amount of increase highly.
Background technology
At present, the rotating shuttle device technology comparative maturity of flat seam machine, the external diameter of shuttle is 21mm, be highly 9mm, but in operating process, the line on shuttle often easily uses, and needs coiling again, affects production efficiency.
The utility model content
The purpose of this utility model is to provide a kind of shuttle coiling amount and is the large flat seam machine of coiling amount of 2 times of existing shuttle coiling amounts.
The purpose of this utility model is achieved in that the flat seam machine that a kind of amount of coiling is large, comprise the rotating shuttle device that is arranged on the needle plate of flat sewing machine downside, the interior shuttle that described rotating shuttle device comprises outer shuttle and supporting outer shuttle rotation, cutting facility is configured in the top of rotating shuttle device, wherein, the Nei Suonei of described rotating shuttle device is equipped with shuttle, and the external diameter of shuttle is 25mm, is highly 10mm.
According to the large flat seam machine of a kind of amount of coiling of the above, wherein, the moving knife of described cutting facility is arranged on the top of outer shuttle, is provided with the gap between cutting facility and moving knife; Moving knife is fixedly connected on an end of trimming knife rest, an end and the trimming knife rest of connecting rod is hinged, the other end and the trimming crank hinged, the trimming knife rest is sleeved on the lower shaft of front shaft sleeve front side.
According to the large flat seam machine of a kind of amount of coiling of the above, wherein, described moving knife is spirally connected by two screwed holes and two screws and trimming knife rest, and the arc radius of moving knife is 21.1mm.
According to the large flat seam machine of the described a kind of amount of coiling of upper any one, wherein, described rotating shuttle device is socketed on lower shaft, drives its rotation by lower shaft, and front shaft sleeve is limited in rotating shuttle device and cutting facility and makes the outside, platform lower edge.
The utility model outstanding and useful technique effect compared to existing technology is: the integral body of rotating shuttle device increases to be improved, and improves the coiling amount of shuttle, has avoided the frequent shuttle changing heart in the operating process city, and coiling, improved production efficiency again.

The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-4: the flat seam machine that a kind of amount of coiling is large, comprise the rotating shuttle device 120 that is arranged on needle plate of flat sewing machine 110 downsides, the interior shuttle 122 that described rotating shuttle device comprises outer shuttle 121 and supporting outer shuttle 121 rotations, cutting facility 130 is configured in the top of rotating shuttle device 120, wherein, in the interior shuttle 122 of described rotating shuttle device 120, shuttle 160 is installed, the external diameter R of shuttle 160 is 25mm, and height H is 10mm.
According to the large flat seam machine of a kind of amount of coiling of the above, wherein, the moving knife 134 of described cutting facility 130 is arranged on the top of outer shuttle 121, is provided with the gap between cutting facility 130 and moving knife 134; Moving knife 134 is fixedly connected on an end of trimming knife rest 133, an end and the trimming knife rest 133 of connecting rod 132 is hinged, the other end and tangent line crank 131 hinged, trimming knife rest 133 is sleeved on the lower shaft 150 of front shaft sleeve 140 front sides.
According to the large flat seam machine of a kind of amount of coiling of the above, wherein, described moving knife 134 is spirally connected by two screwed holes and two screws and trimming knife rest 133, and the arc radius of moving knife 134 is 21.1mm.
According to the large flat seam machine of a kind of amount of coiling of the above, wherein, described rotating shuttle device 120 is socketed on lower shaft 150, drives its rotations by lower shaft 150, and front shaft sleeve 140 is limited in rotating shuttle device 120 and cutting facility 130 and makes platform 100 outsides, lower edges.
The internal diameter of shuttle and highly increase, corresponding rotating shuttle increases, and cutting facility is done corresponding adjustment, and improved like this purpose can allow the coiling amount of shuttle compared with prior art double, and avoids frequently changing shuttle, enhances productivity.
Above-described embodiment is only preferred embodiment of the present utility model, is not to limit according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
