Problems solved by technology
This invention has the effect that the mop wheel (rear tug wheel) is lifted separately, and the presser foot maintains the effect of pressing the cloth. However, in the actual use process, it is often necessary to independently lift the presser foot, and the mop wheel is required to press the cloth, so this invention practicability still needs to be improved

Embodiment Construction
[0052] In order to further explain the technical solutions of the present invention, specific examples are given below to illustrate in detail.
[0053] The first embodiment of the cloth pressing driving mechanism of a sewing machine of the present invention, as figure 1 and 2 As shown, it includes a main drive mechanism that synchronously drives the presser foot 6 and the rear tug wheel (not shown); the main drive mechanism includes the first main drive mechanism 1 that drives the presser foot 6 and the rear tug wheel Driven by the second main drive mechanism 2.
[0054] The first main drive mechanism 1 comprises the first lifting drive part 11 that lifts the presser foot 6, and the first push-pull drive part 12 that pushes and pulls the first lift drive part 11; the first push-pull drive part 12 passes through the first The drive shaft 13 is pivotally connected with the first lift drive part 11, and the first push-pull drive part 12 is formed with a first shaft hole 14 mat...

The invention provides a cloth-pressing drive mechanism of a sewing machine.The structure form of a cloth-pressing drive mechanism of a traditional sewing machine is broken through, an auxiliary drive mechanism for separately driving a presser foot or a rear dragging wheel is arranged additionally, the presser foot and the rear dragging wheel can be synchronously driven through main drive mechanisms, the presser foot or the rear dragging wheel can be also separately driven through the auxiliary drive mechanism when required to enable cloth to be always pressed by the presser foot or the rear dragging wheel, the cloth does not easily move or offset and accordingly does not affect sewing, the sewing operation is smoother, the sewing efficiency is high, and the cloth-pressing drive mechanism is novel and reasonable in structure, flexible in operation and good in practicability.The invention further provides a cloth-pressing device manufactured by the cloth-pressing drive mechanism.The cloth-pressing device has the advantages as well.The invention further provides the sewing machine.The sewing machine has the advantages as well.
Description
technical field [0001] The invention relates to the field of machinery, in particular to a cloth pressing driving mechanism of a sewing machine, a cloth pressing device and a sewing machine. Background technique [0002] The structure of the sewing machine is known. The presser foot and the rear tug wheel of the traditional sewing machine are mostly driven by the same drive mechanism for synchronous lifting. Although such a structure can ensure the efficiency of both lifting, it also brings inconvenience in actual use. When you only want to lift one of the presser foot and the rear tug wheel, you need to lift both the presser foot and the rear tug wheel at the same time, which will cause the cloth to be in an unpressed state, and then the cloth will move and dislocate and affect sewing. [0003] In order to solve the aforementioned problems, the Chinese invention patent CN 201510439614.4 discloses a sewing machine based on a fully automatic template split synchronous wheel d...
