产品概述
产品功能
短线头机构（LBH-1790ANB）
底线线头更短，平均长度短于2.5mm
新型短线头机构切线更短，省却了人工剪线头作业。
利用物联网（IoT）管理缝制性能和缝纫机
可通过应用软件管理、浏览和编辑数据
根据缝制产品调整缝纫机数据，以无接触方式将数据传输到市场上销售的安卓系统平板电脑。这样便可以快速检查统一设定，确认缝制流水线的缝纫机状况，更改设定更方便。操作面板还标配了USB接口。可通过U盘轻松进行数据管理和软件更新。
缝制数据进行数字化管理，以确保“稳定的质量”并“缩短设定更改时间”。
可以使用安卓系统平板电脑或U盘从缝纫机中导出量化缝制数据。
* 推荐在Android OS 6.0版本上使用JUKI Smart应用程序。
（已确认5.0及以上版本可运行操作。)
有关如何使用应用软件的信息，请与您所在地区的JUKI分销商联系。
基本性能
更高生产率
最高缝制速度为4,200sti/min，空送速度为200mm/s。连续缝制的循环时间进一步缩短。
循环缝制和连续缝纫
循环缝制
可以记录20个不同的程序，每个程序最多可存储30个不同的花样。
连续缝制
可以在不提升压布压脚的情况下连续缝制两种或多种不同的花样。可以记录20个不同的程序，每个程序最多可存储6个不同的花样。（需要将相关配件更换为选购件。)
所有驱动机构均采用电子化控制
- 送布机构、针送布机构、上切线机构、下切线机构、切布机构、压脚提升机构等均实现电子化控制。
- 所有调整值均数字化，因而操作人员能够在操作面板上进行设定和存储。
舒适的操作环境
- 采用直驱马达，运行噪音小。
- LED灯位于机臂颚下侧，亮度可调。为LBH-1790AN系列所有机型的标准配置。
- 安装了辅助台板（标准附件），更便于放置缝制品。此外，落针位置位于机台中央，使缝制品定位更简便。
多种踏板功能
- 标配了新型步进马达式自动提升装置。有助于减轻操作人员的疲劳。可在一连踏板和两连踏板间切换，方便缝制品定位，也可以指定中途停止。
- 压布压脚提升量可根据需要设定。逆回转针功能使压布压脚的最大提升量可达17mm。
* 请按零件订购两连踏板。
JUKI独有的电子夹线器
（电子面线张力控制系统）- 根据各种缝制条件（线、面料、缝制速度等），可以通过操作面板分别为锁眼的平行部分和套结部分设定面线张力，设定数据可存储在存储器中。
- 可在平行部分和套结部分进行准确的面线张力切换，以实现精美的锁眼缝制形状。能有效防止断线。
- 起缝和缝制结束时可启用面线夹线器。从而防止面线松散及起缝时的脱线。
- 疏缝的面线张力可以单独设定。
粗缝机构有助于实现优美的锁眼缝制
粗缝是针织等弹性面料的有效缝制方法。粗缝：面线被准确卷入，因而不会从纽孔中伸出而造成松线。粗缝可以缝制9圈。
配备多次落刀功能
- 采用JUKI独有的多次落刀功能，即使锁眼尺寸发生变化，也无需更换切刀。小批量生产需要频繁变更纽孔尺寸或进行不同尺寸的锁眼循环缝制时，可根据纽孔尺寸自动设定切刀的落刀次数。
- 双动步进马达式切刀装置，能防止切刀出现落刀/回刀故障。
- 切刀最大可支持41mm的缝制长度。此外，还可以选购支持70mm和120mm的切刀装置。
缝制设定更改简便
缝制品免受油污影响
- 通过先进的干式机头技术，除旋梭部分外，无需供油。使缝制品免受油污影响。
- 通过将旋梭更换为选购的无供油旋梭，可以实现完全干式机头。（在这种情况下，最高缝制速度为3,300sti/min）
旋梭油量的调节
- 打开旋梭盖板即可看到新安装的“旋梭油量调节螺钉”。通过此螺钉，操作人员可以轻松调节旋梭油量。
- 旋梭油箱有油量指示器，加油更方便。
标配31个用于锁眼的缝制花样
最多存储99种不同的花样，可以根据需要通过操作面板进行选择。

*1 This is an optional guage that prevents cloth displacement that can oocur at a stepped part. A presser to be used is B1552781000A/B1552782000 .
*2 The width of the convex part of the needle plate is wider than any convex part of needle plates with other specifications. If this is used with a feed plate with other specifications together, the feed plate may interfere with this.

| Caution | Figure | |||||
|---|---|---|---|---|---|---|
| When replacing the throar plate between LBH-1790A* and LBH-1790A*B, changing the machine type setting in the memory is required since the distance between the needle entry and knife different than the standard type. [Size of needle entry knife groove] LBH-1790A*B,LBH-1796A*: 1mm LBH1790A*,LBH-1795A*,LBH-1790S: 2mm |
 |
|||||
| LBH-1790S, 1796A and 1796AN use the special frame, which if not compatible with LBH-1790S, 1790A, 1790AN, 1790AB, 1790ANB, 1795A and 1795AN. therefore, the presser type 1 to 3 cannot be assembled. | - | |||||
| There is a difference of timing gage in LBH-1790S, 1790A and 1790AN; LBH-1790AB and 1790AMB. Since the thickness of the throat plate is different, the length of the timing gage differs. The hook timing does not change since the total length is the same. |
- | |||||
| When the feed width is more than 5mm with LBH-1790S, 1790A, the presser arm and oil shield need to be replaced. (For details, refer to the parts book, specia specifications 2.) |
- | |||||
| When the feed direction is more than 41mm with LBH-1790S, 1790A, the presser arm needs to be replaced. (For details, refer to the parts book, special specifications 2.) |
