Description
技术领域technical field

背景技术Background technique
目前模板缝纫机一般包括机架及设置在机架上的机头、底线机构和模板传动机构，工作时模板传动机构在控制器的控制下驱动模板按照预设轨迹的运动，由于机头和底线机构的缝纫方向是固定的，模板的运动方向与缝纫方向相反时会造成线迹不美观。At present, the template sewing machine generally includes a frame, a machine head arranged on the frame, a bottom thread mechanism and a template transmission mechanism. The sewing direction of the template is fixed, and when the movement direction of the template is opposite to the sewing direction, it will cause unsightly stitches.
为此有人设计一款机头和底线机构可旋转的缝纫机，如公告号CN103981638B公开一种伸臂旋转式独立驱动自动缝纫设备，包括分别独立驱动的上机头和下机头，上机头包括机头升降组件、机头旋转组件以及机头组件，机头旋转组件固定在机头升降组件上，机头组件固定在机头旋转组件的下部，上机头可升降也能与下机头同步适应性旋转；下机头包括底线旋转组件以及底梭系统，底梭系统设置在底线旋转组件的上部，底线旋转组件带动底梭系统任意方向360 度旋转；上机头和下机头还分别设有伺服控制系统，伺服控制系统控制底线旋转轴的转向与机头旋转轴相互对应且转速相同；该技术下机头和上机头工作时由独立电机驱动，上、下机旋转又需要独立的旋转电机来控制，这样机头必要同时安装工作驱动电机和旋转电机及电机输出的减速机构，由于上机头内部狭小，要安装独立的驱动电机通常将电机外置，这样就会占用机头外侧空间，一方面不够美观，同时机头外部就无法安装其它如裁剪机构、划线、激光切割等装置；同时内部还需要安装减速机构和升降机构结构比较复杂，对加工和配装都提出更高的要求。For this reason, someone designs a sewing machine with rotatable head and bottom thread mechanism, as the announcement number CN103981638B discloses a kind of outrigger rotation type independent drive automatic sewing equipment, including the upper head and the lower head driven independently respectively, and the upper head includes The machine head lifting assembly, the machine head rotating assembly and the machine head assembly, the machine head rotating assembly is fixed on the machine head lifting assembly, the machine head assembly is fixed on the lower part of the machine head rotating assembly, the upper machine head can be lifted and synchronized with the lower machine head Adaptive rotation; the lower machine head includes the bottom thread rotating assembly and the bottom shuttle system. There is a servo control system. The servo control system controls the steering of the bottom line rotation axis and the rotation axis of the machine head. The rotating motor is used to control the machine head. In this way, the working drive motor, the rotating motor and the motor output deceleration mechanism must be installed at the same time on the machine head. Because the inside of the upper machine head is small, it is usually necessary to install an independent drive motor. The motor is usually placed outside the machine head, which will occupy the outside of the machine head. Space, on the one hand, is not beautiful enough, and at the same time, other devices such as cutting mechanism, scribing, laser cutting and other devices cannot be installed outside the machine head; at the same time, the deceleration mechanism and lifting mechanism need to be installed inside. requirements.

本发明考虑目前智能控制缝纫机的上机头和底线机构一般采用独立电机控制上机头和底线机构工作，在上机头和底线机构再配备独立的旋转电机，上机头的体积显示比较庞大，这样一来，上机头侧部无法安装其它辅助装备，因此采用一台旋转电机控制上机头和底线机构同步旋转，相对于现有独立电机驱动上机头和底线机构旋转的结构，本发明减少一台电机和两台减速机构，由于现有的智能缝纫机上机头和底线机构均由独立伺服电机驱动，机头组件的连接座和悬伸臂内部空间都是没有安装传动机构，因而本发明将旋转电机设置在内部空间较为宽余的机头组件连接座的内部，通过主动带轮和同步带轮齿比的变化实现减速效果，结构更加简单合理，减少旋转电机和减速机构可以节约成本，并充分利用缝纫机内部空间，使得装配更加方便；同时上转轴采用花键轴既实现上机头的和底线机构同步旋转，又能实现上机头的自由升降，克服现有传动带传动机构无法实现升降运动的问题，从而实现结构简单合理，造价更低、装配方便、可靠性好的特点。The present invention considers that the upper machine head and the lower thread mechanism of the current intelligent control sewing machine generally use independent motors to control the upper machine head and the lower thread mechanism, and the upper machine head and the lower thread mechanism are equipped with independent rotating motors, and the volume display of the upper machine head is relatively large. In this way, other auxiliary equipment cannot be installed on the side of the upper machine head, so a rotating motor is used to control the synchronous rotation of the upper machine head and the lower thread mechanism.
