技术领域technical field

本发明涉及机械领域,具体涉及一种通畅顺利的缝纫机的压布驱动机构、压布装置及缝纫机。The invention relates to the field of machinery, in particular to a cloth pressing driving mechanism, a cloth pressing device and a sewing machine of a smooth and smooth sewing machine.

背景技术Background technique

缝纫机的结构已为公知,传统的缝纫机的压脚和后拖轮大多由同一驱动机构进行同步升降驱动,这样的结构虽可保证二者升降的效率,但也在实际使用过程中带来不便,如当只想抬起压脚和后拖轮之一时,需将压脚和后拖轮同时都抬起,会造成布匹处于没被压住的状态,进而出现布匹窜动错位而影响缝纫的情况。The structure of the sewing machine is well known. Most of the presser foot and the rear tug of the traditional sewing machine are driven by the same driving mechanism for synchronous lifting and lowering. Although this structure can ensure the lifting and lowering efficiency of the two, it also brings inconvenience in the actual use process. When you only want to lift one of the presser foot and the rear tug, you need to lift both the presser foot and the rear tug at the same time, which will cause the cloth to be in a state that is not pressed, and then the cloth will move and dislocate, which will affect the sewing.

为了解决前述问题,中国发明专利CN 201510439614.4公开一种基于全自动模板分体同步轮装置的缝纫机,包括缝纫机主体,缝纫机主体上设置有拖轮抬压机构和抬压脚机构,所述缝纫机主体的机壳后盖板设置有抬压拖轮电磁铁,抬压拖轮电磁铁带动拖轮曲柄轴转动,拖轮曲柄轴一端伸入机壳内部,拖轮曲柄轴的拨杆部抵在拖轮提升右杠杆的右端,拖轮提升右杠杆的旋转支点安装在机壳上,拖轮提升右杠杆的左端通过拖轮提升拉杆连接至所述拖轮抬压机构;所述拖轮提升右杠杆的右端连接有膝控提升顶杆,膝控提升顶杆的下端伸出机壳并与油盘上的膝控提升装置连接,膝控顶杆的升降带动所述拖轮提升右杠杆,进而带动上述拖轮抬压机构。机壳内设置有抬压脚电磁铁,抬压脚电磁铁的输出杆抵在压脚提升右杠杆的右端上,压脚提升右杠杆的旋转支点安装在机壳上,压脚提升右杠杆的左端通过压脚提升拉杆连接至所述抬压脚机构。所述缝纫机主体的针板上设置有供机针穿过并勾线的下导套,下导套可嵌入适配的模板上的导向槽。所述针板上设置有橡胶送步牙和塑料高低压脚。所述缝纫机主体还包括一感应装置,感应装置用于检测机针上行穿出布料时发出控制信号至控制器,控制器根据该信号控制机壳后侧的步进电机启动;感应装置在机针下行刺入布料时发出控制信号至控制器,控制器根据该信号控制机壳后侧的步进电机暂停,步进电机的电机轴通过万向联轴器带动拖轮运转;所述步进电机、拖布机构、万向联轴器和拖轮抬压机构组成拖布机。所述拖轮的表面设置有硅胶轮。该发明具有拖布轮(后拖轮)单独抬起,压脚保持压布状态的效果,但是在实际使用过程中,经常是需要压脚进行独立升降操作,而需拖布轮压住布匹,所以该发明的实用性仍有待提高。In order to solve the aforementioned problems, Chinese invention patent CN 201510439614.4 discloses a sewing machine based on a fully automatic template split synchronizing wheel device, comprising a sewing machine body, and a tug-lifting mechanism and a foot-lifting mechanism are arranged on the sewing machine body. The rear cover plate of the casing is provided with an electromagnet for lifting and pressing the tug, which drives the crank shaft of the tug to rotate. The rotating fulcrum of the lifting right lever is installed on the casing, and the left end of the tug lifting right lever is connected to the tug lifting and pressing mechanism through the tug lifting rod; The lower end of the mandrel extends out of the casing and is connected to the knee-controlled lifting device on the oil pan. The lifting and lowering of the knee-controlled mandrel drives the tug to lift the right lever, which in turn drives the tug-lifting mechanism. A presser foot lifter electromagnet is arranged in the casing, the output rod of the presser foot lifter electromagnet is pressed against the right end of the presser foot lifter right lever, the rotation fulcrum of the presser foot lifter right lever is installed on the casing, and the presser foot lifts the right lever of the right lever. The left end is connected to the presser foot lifting mechanism through the presser foot lifting rod. The needle plate of the main body of the sewing machine is provided with a lower guide sleeve for the needle to pass through and hook the thread, and the lower guide sleeve can be inserted into the guide groove on the matching template. The needle board is provided with rubber step feeding teeth and plastic high and low pressure feet. The main body of the sewing machine also includes an induction device, which is used to detect when the needle goes up and out of the cloth and sends a control signal to the controller, and the controller controls the stepper motor on the rear side of the casing to start according to the signal; When going down into the cloth, a control signal is sent to the controller, and the controller controls the stepper motor on the rear side of the casing to suspend according to the signal, and the motor shaft of the stepper motor drives the tug to run through the universal coupling; the stepper motor, The mopping mechanism, universal coupling and tug lifting and pressing mechanism constitute the mopping machine. The surface of the tug wheel is provided with a silicone wheel. This invention has the effect that the cloth mopping wheel (rear tug wheel) is lifted independently, and the presser foot is kept in the state of pressing the cloth. However, in the actual use process, the presser foot is often required to be independently lifted and lowered, and the cloth mopping wheel is required to press the cloth, so this invention The practicality still needs to be improved.

鉴于此,本案发明人对上述问题进行深入研究,遂有本案产生。In view of this, the inventor of this case has conducted in-depth research on the above-mentioned problems, and this case came into being.

In the middle, the main drive mechanism can synchronously drive the presser foot and the rear tug, and the auxiliary drive mechanism can drive the presser foot or the rear tug separately when needed, so that the cloth is always pressed by the presser foot or the rear tug, and the cloth is not easy to move. Misalignment affects sewing. The specific operation is as follows: the main drive mechanism drives the presser foot through the first main drive mechanism, and drives the rear tug through the second main drive mechanism; the first main drive mechanism uses the first push-pull drive member to drive the first The elevating drive member performs push-pull drive. When the auxiliary drive mechanism independently drives the presser foot, regardless of the structure of the second main drive mechanism, the auxiliary drive mechanism replaces the first push-pull drive member with the auxiliary push-pull drive member. Push-pull drive is carried out, and then the first lift drive member is used to lift the presser foot. During the push-pull drive process of the auxiliary push-pull drive member to the first lift drive member, the first drive shaft utilizes the excess space of the first shaft hole to move freely. and will not be affected by the first shaft hole and the first push-pull drive member; or, the second main drive mechanism uses the second drive shaft to push and pull the second lift drive member through the second push-pull drive member. When the rear tug is driven independently, no matter what the structure of the first main drive mechanism is, the auxiliary drive mechanism uses the auxiliary push-pull drive member to replace the second push-pull drive member to push-pull the second lift drive member, thereby enabling the second lift drive member to push and pull the second lift drive member. The rear tug is driven up and down, and in the process of the auxiliary push-pull drive part pushing and pulling the second elevating drive part, the second drive shaft uses the excess space of the second shaft hole to move freely without being affected by the second shaft hole and the second push-pull. Of course, the first main drive mechanism can also use the first drive shaft to push and pull the first lift drive member through the first push-pull drive member, and the second main drive mechanism can use the second push-pull drive member to use the second drive. The shaft pushes and pulls the second lift drive member, but the auxiliary drive mechanism independently drives the presser foot or the rear tug. The main power device drives the main drive member, and the main drive member pushes and pulls the first push-pull drive member and the second push-pull drive member.
